Description

CROSS REFERENCE TO RELATED APPLICATION
• This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/460,700, filed Jan. 5, 2011, which application is hereby incorporated by reference in its entirety.
TECHNICAL FIELD
• The present disclosure relates to a holder or a stand for use with electronic devices including but not limited to tablet personal computers (e.g., an iPad® or an iPad2®), e-book readers (e.g., a Nook™), smart phones (e.g., an iPhone®), cellular phones, GPS units, touch screen devices, digital display devices, electronic notebooks, and the like.
BACKGROUND
• When using an electronic device such as a tablet personal computer (also referred to herein simply as a “tablet”, a user is normally required to hold the tablet in his or her hands which can pose problems if the user is engaging in another contemporaneous activity, such as playing a musical instrument, where his or her hands are required or if the user does not wish to hold the tablet the entire time that he or she is working on the tablet. The user may then be required to place the tablet on a table, countertop, or another location which may not be suitable for the activity for which he or she is using the tablet. Thus, there is a need in the art for a hands-free holder or stand for an electronic device such as a tablet that includes rapid and easy engagement and removal.
• Furthermore, what might be desired in the art is a hands-free stand/holder for electronic devices such as tablets that allow for full 360-degree rotation of the electronic devices for not only landscape and portrait viewing but also for a wide range of swivel and tilt in all directions (e.g., positioning at least about 3-axes such as yaw, pitch, and roll) to a preferred inclination and orientation.
• Most modern electronic devices now alter their displayed image orientation by the rapid change from physical landscape to portrait orientation simply by rotating the electronic device 90 degrees to the new preferred orientation. These newer electronic devices sense their attitude using an internal sensor such as an accelerometer. These accelerometers can have as many as 3-axes and can be electronically monitored by the computer and converted to data for use with their software. The software can then determine finger gestures or rotational accelerations which the user creates to change the orientation of the image on the electronic device. For example, the display can quickly change from portrait to landscape left with a 90-degree counterclockwise rotation of the device.
• Because of this rapid and frequent need to change the orientation from landscape to portrait, or, vice versa, it might also be desirable, in addition to providing a wide-range of swivel and tilt in all directions (e.g., positioning at least about 3-axes such as yaw, pitch, and roll), to allow ease and speed of motion in only the roll axis without disturbing already set preferred yaw and pitch axes.
SUMMARY
• According to one example embodiment, the present disclosure relates to a hands-free holder/stand for use with an electronic device such as a tablet, the holder including a base, a neck, a ball and socket connector, and a head.
• According to another example embodiment, the neck portion of the holder may include a rigid portion, a crimp portion, a flexible portion, and a threaded stud portion that is configured to be fastened to the ball and socket connector.
• According to another example embodiment, the head of the holder is mechanically coupled to the electronic device. According to one embodiment, the head of the holder is directly coupled to the electronic device such as with flexible portions that elastically deform to snap-fit the head to the electronic device. According to another embodiment, the head is coupled to a converter structure that is separately coupled to the electronic device. As such, according to certain example embodiments, the converter structure may be coupled to the electronic device via adhesives and the head of the holder may be coupled to the converter structure with latches, cams, threads, or magnets.
• According to another example embodiment, the holder for an electronic device includes a head with elastically flexible portions configured to removably receive the electronic device with a snap-fit interlock, a neck for supporting the head relative to a surface, and an attitude adjustment mechanism such as a hinge, a pivot, a swivel, or a ball and socket connector coupling the neck to the head, the attitude adjustment mechanism configured to allow adjustment of the yaw, the pitch, and the roll of the electronic device with respect to the neck when the electronic device is coupled to the head.
• According to another example embodiment, the holder for an electronic device includes a head configured to removably receive the electronic device, a neck for supporting the head relative to a surface, a ball and socket connector coupling the neck to the head, the ball and socket connector configured to allow adjustment of the yaw, the pitch, and the roll of the electronic device relative to the neck when the electronic device is coupled to the head, and a rotary joint that allows further independent adjustment of the roll of the electronic device without disturbing the yaw and the pitch of the electronic device after the yaw, the pitch, and the roll of the electronic device have been initially adjusted and locked using the ball and socket connector.
• According to another example embodiment, the present disclosure relates to a holder system for an electronic device that includes a converter that is configured to be attached to the electronic device and a head that is configured to be attached to the converter with mechanical couplings such as for example with cams, latches, threads, or magnets, wherein the head includes at least one movable portion that is configured for detaching the head from the converter.

DETAILED DESCRIPTION
• Referring now toFIGS. 1-9, a first embodiment of aholder10 having features that are examples of inventive aspects in accordance with the present disclosure is illustrated. Theholder10 is configured for use with a variety of electronic devices including but not limited to tablet personal computers (e.g., an iPad® or an iPad2®), e-book readers (e.g., a Nook™), smart phones (e.g., an iPhone®), cellular phones, GPS units, touch screen devices, digital display devices, electronic notebooks, and the like. The different embodiments of the holders of the present disclosure will be described and shown as being used with an electronic device in the form of a tablet personal computer12 (also referred to herein simply as a “tablet”). It will be understood that atablet12 is simply one example of an electronic device for which the holders of the present disclosure can be configured for and on which the holders of the present disclosure can be used. Atablet12 will be used as a non-limiting example device for the purpose of illustrating the inventive features of the different embodiments of the holders of the present disclosure, without affecting the scope of the inventive features, unless specified otherwise.
• Still referring toFIGS. 1-9, theholder10 generally includes abase14, aneck16, a ball andsocket connector18, and ahead20. In the depicted example embodiment, theneck16 includes arigid portion22, acrimp portion24, aflexible portion26, and a threadedstud portion28. Therigid portion22 is configured to be attached to thebase14 of theholder10. Thecrimp portion24 is configured to couple theflexible portion26 of theneck16 to therigid portion22 of theneck16. The threadedstud portion28 is attached to an end of theflexible portion26.
• As will be described in further detail below, thebase14 of the depicted embodiment includes an essentially flat platform that includeslateral extensions30 that create a V-shapedstructure32. According to certain embodiments, thebase14 may be manufactured of metal and may include surface texturing, giving the base14 a rough feel.
• As will be described in further detail below, therigid portion22 of theneck16 includes adistal end34 and aproximal end36. At itsproximal end36, therigid portion22 is configured to be attached to the base14 at the apex38 of the V-shapedplatform32. Therigid portion22 may be manufactured of a metal pipe having, according to certain embodiments, a diameter of about 19 millimeters and a length of about 300 millimeters.
• Theflexible portion26 of theneck16 also includes adistal end40 and aproximal end42. Theflexible portion26 is attached at itsproximal end42 to therigid portion22 via thecrimp portion24 of theneck14. According to certain embodiments, theflexible portion26 may be made out of metal gooseneck tubing having a diameter of about 18 millimeters and a length of about 600 millimeters. Thedistal end40 of theflexible portion26 may be configured to receive the threadedstud28 having a proximal threadedend44 and a distal threadedend46. As depicted, thebody48 of the threadedstud28 may be provided with a 45-degree bend.
• As will described in further detail below, the ball andsocket connector18, which provides for pivotal adjustment of thehead20 with respect to thebase14 and theneck16, includes aball50 that is configured to receive thedistal end46 of the threadedstud28.
• Thehead20 of theholder10, in the depicted embodiment, includes a three-point clamp structure52 having afirst arm54 on afirst side56 and second andthird arms58,60 on asecond side62 of thehead20. The second andthird arms58,60 are positioned on the two corners of thesecond side62 of thehead20. In the depicted embodiment, thehead20 of theholder10 is configured to be mechanically coupled to thetablet12. According to one embodiment, thehead20 of theholder10 is directly coupled to theelectronic device12 via the first, second andthird arms54,58,60 that elastically flex to receive thetablet12. In one embodiment, thehead20 or portions thereof may be formed out of a polymeric material to provide the desired flexibility.
• The present disclosure and the embodiments described herein enable a user to use his or hertablet12 hands-free and to adjust thetablet12 in approximately a 360-degree of freedom to preferred vertical and horizontal positions, in a preferred inclination and orientation, including for landscape and portrait viewing. According to one example embodiment, thetablet12 can be adjustable360 degrees along a roll spherical axis and about 45 degrees along the yaw and pitch spherical axes (seeFIG. 10).
• Referring now specifically toFIG. 2, thebase14 of theholder10 is illustrated. According to the depicted embodiment, thebase14 includes the flat platform structure that includeslateral extensions30 that create a V-shape. As noted above, thebase14 may be manufactured of metal and may include surface texturing, giving the base a rough feel. Thelateral extensions30 forming the V-shape structure32 of the base14 may provide great stability to cantilever thetablet12 toward a person seated or reclined.
• According to one embodiment, thebase14 has a total length of about of 22.702 inches and a total width of about 10.50 inches, eachlateral extension30 having a width of about 3.125 inches. As shown inFIG. 2, the V-shape of thestructure32 results in the apex38 being at a desired distance of about 11.351 inches from the outer edge of eachlateral extension30 and at a desired angle of about 82 degrees. The V-shaped, essentiallyflat base14 allows for greater stability and the rough texture of the base14 combined with the essentially flat V-shapedstructure32 form allows for placement on the floor as well as placement between soft surfaces such as a mattress and box springs for use in a bed.
• Now referring toFIGS. 1 and 3, therigid portion22 of theneck16 of theholder10 is configured to attach to the base14 at the apex38 of the V-shapedplatform32. As depicted, theproximal end36 of therigid portion22 may include a threadedbore64 for receiving a fastener for the purpose of attaching to thebase14. Therigid portion22 may allow for greater strength and stability of theholder10.
• As shown inFIGS. 1,3, and6-8, theflexible portion26 of theneck14, as noted above, may include metal gooseneck tubing having distal and proximal ends40,42. Theflexible portion26 is attached to therigid portion22 of theneck14 via thecrimp portion24 of theneck14 as shown inFIG. 3. Theflexible portion26 is capable of maintaining adjustment of thedistal end40 thereof to a preferred vertical and horizontal position. Theflexible portion26 of theneck14 is configured to allow for theholder10 to hold atablet12 of approximately 900 grams at any angle when thebase14 is placed on a flat surface.
• As noted above, thedistal end40 of theflexible portion26 is configured to receive the threadedstud28 having a proximal threadedend44 and a distal threadedend46. As depicted, thedistal end40 of theflexible portion26 may include a threadedinternal bore66 for receiving the threadedproximal end44 of thestud28. The 45-degree bend provided to thebody48 of the threadedstud28 may allow for additional range of motion of theholder10.
• Referring now toFIGS. 1,6,8, and9, the ball andsock connector18 of theholder10 includes asocket68 that is configured to engage thehead20 of theholder10 and theball50 that is configured to be captured within thesocket68 with a threadednut70 that is fastened on thesocket68. The ball andsocket connector18 allows for pivotal adjustment of thehead20.
• Theball50, which has a diameter of about ¾″ in one embodiment, includes an internally threaded bore72 that receives thedistal end46 of the threadedstud28. Once theball50 is firmly engaged with the threadedstud28, the slidable, rotatable interaction of theball50 within thesocket68 allows thehead20 of theholder10 to have approximately 360-degree adjustability along at least one axis. According to one example embodiment, thetablet12 can be adjustable360 degrees along a roll spherical axis and about 45 degrees along the yaw and pitch spherical axes (seeFIG. 10). This allows for not only landscape and portrait viewing of an attachedtablet12 but also allowing for a wide rage of swivel and tilt in all directions to a preferred inclination and orientation.
• Thesocket68, in the depicted example embodiment, aportion74 that receives theball50. Theportion74 can be clamped against theball50 via the threadednut70 once a desired position for thetablet12 is established and theball50 is ready to be locked in place.
• Referring now toFIGS. 1,4-6,8, and9, the ball andsocket connector18 is configured to be attached to a rear76 of thehead20 of theholder10 as shown. Thehead20 may be removably attached to the ball andsocket connector18. Thesocket portion68 may include an engagement mechanism at the end opposite from the clamping end for removable attachment to thehead20, wherein thehead20 may include acomplementary engagement mechanism78 for removably receiving thesocket68.
• As noted above, thehead20 or portions thereof may be made of polymeric material, which provides the flexibility needed to receive and cradle thetablet12 in a three-point clamp.
• In the depicted embodiment, thehead20 includes thefirst arm54 on thefirst side56 and second andthird arms58,60 on thesecond side62 of thehead20. The second andthird arms58,60 are positioned on the two corners of thesecond side62 of thehead20. Each of thearms54,58,60 may include forwardly extendingportions80 at the outer ends thereof for receiving and cradling thetablet12. The forwardly extendingportions80 may includetabs82 that extend in a direction toward a center of thetablet12. Thetabs82 are configured to provide a snap-fit engagement between thehead20 and thetablet12 and limit removal of thetablet12 from thehead20. The polymeric make-up of thehead20 allows for a lightweight design and easy insertion and removal of thetablet12.
• With the features of the above-described embodiment, atablet12 may be positioned in nearly any convenient orientation for operation and viewing. When thehead20 of theholder10 is in the desired position, the ball andsocket connector18 can be tightened by rotating thenut70, resulting in a locked secure fixed orientation.
• Although in the foregoing embodiment, theholder10 is described and illustrated as having a base14 that is configured to stand on a surface, in other embodiments, thebase14 can be configured for mounting to an appliance surface, a dashboard, a table top, a desk top, a wall surface, a floor surface, or to any desired surface.
• The above describedholder10 includes features for adjusting orientation, attitude, and position of the electronic device such as atablet12. Theholder10 provides direct secure fixed engagement of thetablet12 regardless of its orientation, attitude, and position. Thehead20 of theholder10 provides for rapid and easy engagement and removal such as in a quick-connect and quick-disconnect mechanism for thetablet12. Although in the depicted example embodiment, theholder10 is described and illustrated as using a ball andsocket connector18, the 360-degree adjustability may be provided using a variety of other mechanical methods including swivels, bearings, flexible members, magnets, detents, pivots, hinges, and combinations therebetween.
• Referring now toFIGS. 10-12, a second embodiment of aholder100 having features that are examples of inventive aspects in accordance with the present disclosure is shown. Although theholder100 is shown without a base, it should be noted that any of the features related to the base14 described above for the first embodiment of theholder10 are fully applicable to the second embodiment of theholder100.
• As noted previously, many modern electronic devices such astablets12 now alter their displayed image orientation by the rapid change from physical landscape to portrait orientation simply by rotating the device 90 degrees to the new preferred orientation. These newer electronic devices such astablets12 sense their attitude using an internal sensor such as an accelerometer. These accelerometers can have as many as 3-axes and can be electronically monitored by the computer and converted to data for use with their software. The software can then determine finger gestures or rotational accelerations which the user creates to change the orientation of the image on the electronic device. For example, the display can quickly change from portrait to landscape left with a 90-degree counterclockwise rotation of thetablet12.
• Thus, in addition to providing a wide-range of swivel and tilt in all directions (e.g., positioning in at least 3-axes such as yaw, pitch, and roll), as featured in the first embodiment of theholder10 ofFIGS. 1-9, the second embodiment of theholder100 additionally includes features for allowing ease of motion in the roll axis without disturbing the preferred yaw and pitch axes, which accommodates for rapid and frequent need to change from landscape orientation to portrait orientation of thetablet12. The yaw, pitch, and roll axes have been diagrammatically illustrated inFIG. 10.
• In the second embodiment of theholder100 illustrated specifically inFIGS. 11 and 12, a swiveling or rotary joint102 has been added to a ball andsocket connector104 so that theholder100 can be easily rotated from landscape orientation to portrait orientation without disturbing the already set and locked desired yaw and pitch axes.
• As will be described in further detail below, the rotary swiveling joint102 can include additional features to provide stable positions at 90-degree intervals. These stable positions can be provided by features such as detents or locks, or even magnetic structures creating magnetic nodes.
• For example, the rotary joint102 may be provided by a spring engaged pawl that can be used to nest into suitable notch at each 90-degree interval. When a pawl is nestled into a notch, rotation would be suspended until a predetermined break-away torque is imparted. As such, theholder100 can provide easy rotation between quadrants such as 9 o'clock, 12 o'clock, and 3 o'clock on a clock dial, but relative stability at each quadrant point. If magnets are used, magnets can be used to provide tactile feedback at each of the quadrants or provide the holding torque with stable resting nodes.
• In addition, the rotary joint102 can provide end stops106 in each rotational direction to limit the degrees of freedom to any desired angle such as 180 degrees. The benefit of limiting the rotation to 180 degrees may be that once the rotation is stopped by anend stop106, theholder100 itself can be used as a torque arm to tighten or loosen a threadednut108 of the ball andsocket connector104. Without any rotation limits, thenut108 could be difficult to tighten as the joint102 might allow ahead110 of theholder100 to free wheel.
• As will be described in further detail below, the end stops106 can be provided bytabs112 that engage opposingsurfaces114. When a user wants to tighten or loosen a ball116 of the ball andsocket connector104, the end stops106 can be engaged to provide the needed torque.
• Alternately, instead of providing end stops106, any features that are opposing the rotational direction of the threadednut108 can be grasped by the other hand of the user as counter torque for loosening and tightening thenut108.
• As will be described in further detail below, the rotary joint102 that provides rapid change between landscape and portrait orientations about the roll axis without disturbing the yaw and pitch axes can be configured to be easily and effortlessly turned from end to end or have pre-defined nodes of stability.
• Referring now toFIG. 10, a diagram of the degrees of flexibility provided by the ball andsocket connector104 is shown. When using the second embodiment of theholder100, the pitch, yaw, and initial roll axes may be chosen by allowing the ball116 to pivot in any axis until the desired position is selected. Theball nut108 can then be tightened securely to prevent any relative pitch, yaw, or roll motion. However, the additional rotary joint102 of the second embodiment of theholder100 allows controlled rapid motion in the roll axis without disturbing the yaw and pitch axes.
• Referring now specifically toFIGS. 11 and 12, the second embodiment of theholder100 is shown as cradling atablet12. Aside from the additional rotary joint102 between the ball andsocket connector104 and thehead110 of theholder100, the second embodiment of theholder100 can include any of the features of the first embodiment of theholder10, and, thus, those features will not be discussed in great detail herein. For example, theholder100 is shown inFIG. 11 with aneck118 having aflexible gooseneck portion120. Only the differences between the different embodiments of the holders will be described in detail herein.
• FIG. 12 illustrates an exploded view of the ball andsocket connector104 and therotary joint102 of theholder100. Thehead portion110 of theholder100 is similar to thehead portion20 of the first embodiment of theholder10 in that thehead110 is directly snap-fit to an electronic device such as atablet12 via elastically flexible portions.
• The rotary joint102 is formed between asocket member122 of the ball andsocket connector104 and thehead110 of theholder100. The rotary joint102 is formed by acircular protrusion124 on thehead portion110 that receives thesocket member122 with a snap fit. Thecircular protrusion124 defines atrack126 around the outer perimeter thereof for allowing thesocket member122 to rotate about theprotrusion124 to allow quick orientation change about the roll axis.
• In the illustrated example of the rotary joint102,magnets128 are used to provide the holding force and the tactile feedback at each of the quadrants. Both thehead110 and thesocket member122 are populated withmagnets128 that are configured to be aligned in an axial configuration to provide discrete temporary locking positions for the rotary joint102. In the depicted embodiment, asuitable slip disk130 is used to provide a controlled friction-reducing gap betweenmagnets128 of approximately 0.005″ to 0.030″.
• Thesocket member122 is secured to the ball116 of the ball andsocket connector104 with the threadednut108, similar to the first embodiment of theholder10. The ball andsocket connector104, as discussed, provides full adjustability, and, once set and tightened in place, allows the rotary joint102 to be used for quick orientation changes about the roll axis.
• In the depicted embodiment, an end-stop106 is provided for the rotary joint102, wherein thehead portion110 of theholder100 includes anengagement surface114 that is contacted by a pair of oppositely positioned tabs/protrusions112 provided on thesocket member122 to define the end-stops106 (please seeFIG. 29 for a similar feature). Theengagement surface114 is shown at the 3 o-clock position on thehead110 and interacts with the two opposingprotrusions112 on therotary socket122 to limit the rotation from −90, to +90 degrees. As depicted, ascrew132 holds the rotaryjoint assembly102 together and an adhesive graphic134 may be used to hide thescrew132 and decorate theholder100.
• The magnetic force between themagnets128 of thesocket member122 and themagnets128 of thehead110 may be broken by rotating thesocket122 with respect to thehead110 in either direction. Eachmagnet128 around the circular periphery of both thehead110 and thesocket122 provides a discrete locking position about the roll axis.
• FIGS. 13-15 illustrate a third embodiment of aholder200 having features that are examples of inventive aspects in accordance with the present disclosure. The third embodiment of theholder200 is similar in concept and operation to the second embodiment of theholder100 except that the third embodiment of theholder200 includes a rotary joint202 with radially alignedmagnets128, as shown in the exploded view inFIG. 13.
• FIG. 15 illustrates a cross-sectional view taken along line15-15 ofFIG. 14 illustrating the alignment of themagnets128 of asocket204 of theholder200 with those of thehead206 of theholder200 for providing discrete locking positions. Such a radial alignment arrangement may have the benefit of reduced axial thrust.
• In either of the second and third embodiments of theholders100,200, eighttotal magnets128 may be used, an aligned pair in each quadrant. However, to reduce costs, sixmagnets128 can be used, with the understanding that the holding force provided by themagnets128 will vary from the landscape orientation to the portrait orientation. For example, two pairs would be in alignment at either landscape right or landscape left orientation and three pairs would be in alignment in the portrait orientation, as in the illustrated example ofFIG. 13. In other embodiments, at least one magnet and one steel target may be used to establish the magnetic connection.
• FIGS. 16-33 illustrate aholder system300 including a fourth embodiment of aholder302 having features that are examples of inventive aspects in accordance with the present disclosure and aconverter structure304 for coupling to theholder302 to an electronic device such as atablet12.FIG. 17 specifically illustrates theholder system300 ofFIG. 16 coupled to atablet12.
• In the illustrated example, aneck306 of theholder302 is depicted as including only a threadedstud308, wherein ahead316 of theholder302 is directly attached to abase310 via the threadedstud308. In the depicted example, thebase310 includesopenings312 for mounting the base310 to a variety of different surfaces with fasteners as described above. It should be noted that theneck306 andbase310 illustrated with the fourth embodiment of theholder302 is simply one example configuration and any other configuration such as those described and illustrated for the first, second, and third embodiments of theholder10,100,200 can be used with theholder system300 ofFIGS. 16-33.
• FIG. 18 diagrammatic illustrates the ability of theholder system300 ofFIG. 16 to allow a user to rapidly change the displayed image orientation of thetablet12 between portrait and landscape by rotating the holder 90 degrees. In theholder302 of theholder system300 ofFIGS. 16-33, as in the second and third embodiments of theholder100,200 of the present disclosure,magnets128 can be used to provide tactile feedback at each of the quadrants or provide holding torque with stable nesting nodes.
• As discussed previously, in other embodiments of the holder, instead of usingmagnets128, a rotary joint326 may be provided by a spring engaged pawl that can be used to nest into suitable notch at each 90-degree interval. When a pawl is nestled into a notch, rotation would be suspended until a predetermined break-away torque is imparted. As such, theholder system300 can provide easy rotation between quadrants such as 9 o'clock, 12 o'clock, and 3 o'clock on a clock dial, but relative stability at each quadrant point.
• As will be described in detail below, theholder system300 ofFIGS. 16-33 also provides a quick connect/disconnect feature that enables the user to rapidly remove thetablet12 from theholder system300 and also provides a universal type attachment that allows thesame holder302 to be able to be used on a variety of different devices.
• In the depicted examples ofholders10,100,200 shown inFIGS. 1-15, for example, the head portion of the holder is configured specifically for the electronic device (e.g., a tablet such as an iPad® or an iPad2®) upon which it is attached. Although the head portion of the holders ofFIG. 1-15 may be modified or configured for a variety of different devices such as e-book readers, GPS units, cellular phones, etc., the same holder may not be able to be used with two different types of devices.
• The fourth embodiment of theholder302 forms a part of aholder system300 that provides a universal type docking arrangement, wherein the same arrangement can be used with a variety of devices without having to modify thehead316 of theholder300.
• In certain embodiments, a universal type of a docking arrangement may be provided with movable or adjustable features of thehead portion316 such as arms, fingers, latches, straps, hook-and-loop fasteners (e.g., Velcro™), or adhesive. However, when providing the docking arrangement, it is normally desired that the installation and removal of the electronic device be easy and fast. In the broadest sense, the quick connect/disconnect desire can be accomplished by adapting each electronic device to a given standard docking geometry. In other words, the quick connect/disconnect feature may be provided by converting each electronic device to a given standard holder.
• As such, the depicted embodiment of theholder system300 includes theconverter structure304 that can be adapted to a variety of different electronic devices, wherein theconverter structure304 enables the same “universal” holder (e.g., holder302) to be used with a variety of different electronic devices.
• In certain embodiments, theconverter304 can be permanently or semi-permanently attached to the electronic device using, for example, adhesives. These adhesives can be tailored for long-term permanence using products such as 3M VHB™ foam tapes, or semi-permanence using products such as 3M Command™ adhesive systems.
• As will be described in further detail, theconverter structure304 can include a mechanical interlock with thehead316 of theholder302. In certain embodiments, these mechanical interlock features can be engaged by simple bringing theconverter304 in proximity to thehead316 of theholder302. Once theconverter304 andhead316 are quickly mated, they remain firmly attached to each other. In this way, theelectronic device12 remains fixedly connected to thehead unit316 and can benefit from the configurable positioning of a ball andsocket joint318 of theholder302. Further, theelectronic device12 can benefit from easy and speedy clockwise or counterclockwise rotation about the roll axis, stopping at each quadrant as desired.
• In the depicted embodiment, thehead unit316 also allows for rapid and easy removal from theconverter304. Removal can be provided by disengaging the mechanical feature by pushing a button, sliding or rotating a lever, a screw, or a cam, twisting, prying or the like. Another method of docking theconverter304 with thehead316 may be provided by using magnets. Neodymium magnets can provide considerable forces in small sizes. These magnets can be separated by simple lateral sliding, or shearing motion.
• One example embodiment of aholder system300 that provides for a quick connect/disconnect arrangement between thehead316 of theholder302 and aconverter structure304 of thesystem300 is described below.
• FIG. 16 illustrates the major components of theholder system300, which may include thebase310, the neck306 (in this example, the threaded stud308), the ball and socket connector318 (which includes aball320, a threadednut322, and a socket member324), thehead316, and theconverter structure304.
• InFIG. 17, theholder system300 is shown as being mounted to a planar surface using thebase310. Alternatively, instead of utilizing abase310, theball320 can be attached using the threadedstud308, to any structure such as a post, a rod, a flexible metal gooseneck, an appliance unit, a wall ceiling, a fuselage, a dashboard, etc.
• Theelectronic device12 is adapted or converted by attaching the converter structure304 (shown in detail inFIGS. 30-33) to itsback panel13. Theconverter304 can be attached using any mechanical means including pressure sensitive adhesives such as 3M VHB™ or 3M Command™ adhesive.
• Referring back toFIG. 16, thehead316 can be readily attached to the adaptedelectronic device12 by interfacing with theconverter304.FIGS. 16 and 20 depict theconverter304 being attached with pressuresensitive adhesive352 and thehead316 being releasably attached toconverter304 usingneodymium magnets328. Thehead316 can have its yaw, pitch, and roll altered by adjustments to the ball andsocket connector318 which can be locked by tightening the threadednut322. Additionally, once thehead316 is attached to theconverter304 and theball320 locked in place, the displayed image orientation of theelectronic device12 can be rapidly changed between portrait and landscape by using arotary joint326 of theholder302.
• FIG. 18 shows the rear view of theholder system300 attached to atablet12 showing the relative orientations of the tablet12: landscape left, portrait, and landscape right.
• Referring specifically now toFIGS. 21-29, thehead316 includes a pair of slidingdetachment members330. Thedetachment members330 are configured to slide side-to-side from a mounting position to a release position. Thedetachment members330 include features for allowing an operator's thumb and fingers to squeeze the members to a release position. As shown inFIGS. 24 and 26, compression springs332 bias thedetachment members330 to a mounting position. Analignment indicator334 that associates or keys thehead316 of theholder302 with theconverter structure304 on theelectronic device12 can be used to keep theelectronic device12 in the preferred orientation when re-connecting.
• Eachdetachment member330 includes anarcuate magnet328 attached thereto withadhesive tape336.FIG. 26 illustrates thehead316 from the front. The arcuate-shapedmagnets328 extend past the dovetail wedgedgrooves338 and slide on atrack340 laterally. The compression springs332 provide a biased force to keep thedetachment members330 mildly biased in the mounting position. It is also anticipated that as thehead unit316 is brought within magnetic proximity tosteel targets342 within theconverter structure304, thedetachment members330 will be magnetically biased outwardly. Themain body344 of thehead316 includes a conical frustum type centering face which serves to align theconverter structure304 axially into thehead unit316 and keep it aligned during the sliding of thedetachment members330 for release.
• Referring now toFIGS. 30-33, theconverter304 is shown in detail. The main body346 of theconverter structure304 may be formed from a suitable molding process such as rim molding, injection molding or the like. Suitable resins may include polyethylene (PE) for its low-cost, lubricity and durability. Additionally, PE can be molded in very thin sections which may shield the steel targets342 of theconverter304. Thermosets such as urethanes and polyurethanes can also be used. They offer great durability and toughness but with increased surface friction. In still another embodiment, the converter main body346 can have a plastic film applied over the steel targets342 such as vinyl or polycarbonate with silk screening as desired. When thedetachment members330 of thehead316 are in their outermost orientation, they are in line with the corresponding steel targets342. These steel targets342 are of such thickness so as to yield the majority of magnetic attraction force without being excessively thick. Thetargets342 can be plated steel to reduce corrosion with electroless nickel, yellow zinc or similar treatments. Thebottom350 of theconverter304 may be used to provide room for anadhesive strip352. 3M Command™ can be used to provide for a semi-permanent attachment and can be released by pulling on a tab to release the adhesive with shear forces. 3M VHB™ can be used for a more permanent attachment.
• FIG. 31 illustrates an exploded view showing theconverter304 with itsalignment sides354 and centeringcircle356,steel targets342, andadhesive pad352.FIG. 30 shows theconverter304 being adhesively secured to theback13 of anelectronic device12. Theconverter304 is aligned with the center of thedevice12, wherein itsalignment indicator334 would be positioned at the right-hand side of thedevice12 when thedevice12 is viewed in the portrait orientation.
• Regarding the operation of theholder system300,FIG. 20 illustrates the attachment between theconverter structure304 and thehead316 of theholder302, wherein theconverter304 is shown as being adhesively attached to theback13 of theelectronic device12. In the illustrated example, thehead316 is magnetically attached to theconverter structure304. The cross-section illustrated inFIG. 20 is taken along line20-20 ofFIG. 19, wherein one of thedetachment members330 is shown in an engaged position and one is shown in a release position. As such, inFIG. 20, one of thedetachment members330 is shown with itsmagnet328 directly in line with acorresponding steel target342 within theconverter304. Theother detachment member330 is shown in a release position wherein the majority of the magnetic flux has been weakened such that the attraction forces holding thehead316 to theconverter304 are greatly reduced.
• In the depicted embodiment, as shown inFIG. 24, thedetachment members330 include strong neodymiumiron boron magnets328 that are permanently attached to themembers330. And, as illustrated inFIG. 31, the steel targets342 may be permanently integrated into theconverter structure304 by adhesive, mechanical means, or insert molding.
• The magnetic contact force between thehead316 and theconverter304 is greatest when themagnet328 is in direct contact with itssteel target342, but a thin-film of polymer can reduce the sliding friction and may be desired to cosmetically decorate the converter. The thicker the film of polymer, the lower the magnetic coupling force will be.
• In one example embodiment, if each arcuate-shapedmagnet328 has a surface area of about 1.308 square inches at about 0.125″ thickness and is magnetized to an N42 strength, themagnet328 can have a maximum pull force of about 16.94 lbs. against a suitablythick steel target342. When themagnet328 is spaced a distance from thesteel target342 with about a 0.020″ gap, the magnetic force is reduced to about 71% strength, resulting in about 11.95 lbs. Thesteel target342 is also desired to be very thin to have the least impact on the thickness of theconverter304. Asteel target342 of at least about 0.078″ provides the maximum magnetic coupling force. Reducing this target thickness to about 0.060″ for 16 gauge steel nets only 92% of full force. The total resulting force is then calculated to be 11.95×92%=10.99 lbs. Twomagnets328 therefore can provide almost about 22 lbs. of holding force.
• FIG. 22 illustrates a side view of thehead316 and shows the large surface area of thedetachment members330 to allow the operators thumb and fingers to squeeze thedetachment members330.FIG. 23 illustrates the top view of thehead316 and shows the generous spacing available to the user for access for tightening and loosening the threadedball nut322. Theball nut322 is shown with suitable features323 to allow traction or grip to tighten and loosen the nut.FIG. 25 illustrates the rear view of thehead316 and shows thealignment indicator334 so that theelectronic device12 may be repeatedly re-attached to thehead unit316.
• InFIG. 25, it can also be seen that thedetachment members330 are wedge shaped and fit into thedovetail grooves338 in the headmain body344. When themagnets328 are permanently installed using an adhesive336 such as 3M VHB™, thedetachment members330 are configured such that they cannot be removed, but can only move laterally from an outer mounting position to an inner release position. When thedetachment members330 are moved inwardly with a squeezing motion, the residual magnetic forces allow easy but controlled release of theelectronic device12 from theholder302.
• As noted previously, both of thedetachment members330 are biased outwardly to thesteel target plates342, the biasing forces being provided by theinternal springs332 shown inFIGS. 24 and 26. Thedetachment members330 are constrained to lateral sliding motion due to a dovetail type joint between themain body344 of thehead316 and thedetachment members330, as shown inFIG. 25.
• Although thetargets342 provided in theconverter structure304 that are used to attract themagnets328 provided in thedetachment members330 of thehead316 have been described as being steel, it should be noted that steel is only one example material and other suitable metals may be used.
• FIG. 24 illustrates an exploded view showing the components of thehead unit316, especially those features that relate to the rotary joint326 between thesocket324 and thehead316.
• As shown, theball nut322 is internally threaded to engage withexternal threads360 of therotary socket324. Similar to the second and third embodiments of theholder100,200, four button ordisc magnets128 are bonded into four rotary socket magnet pockets362. Aslip disk364 separates therotary socket324 from the headmain body344 and reduces friction and provides a controllable gap between themagnets128. Fourmagnets128 are bonded into the headmain body344. A Plastite® or othersuitable screw366 may be used to couple the headmain body344 to therotary socket324. A graphic368 can be applied to the centering face of the headmain body344.
• As discussed previously, the ball and socket joint318 provide for spherical adjustments and rigid connection when theball nut322 is tightened. Thecenter screw366 may be provided to keep thesocket324 axially retained to the headmain body344 while allowing rotational motion therebetween. Thescrew366 can be adjusted to provide the desired pre-load for a friction-free yet stable rotary operation.
• FIG. 28 illustrates a cross section of thehead316 showing the axially arrangedmagnets128. The lower set ofmagnets128 are arranged at each of the four quadrants of a circle. Eachmagnet128 may be bonded into thehead body344 using epoxy or CA adhesive. Epoxy adhesive is generally preferred and can build a thickness so that a waffle type depressions are provided into the magnet pocket362. The depressions serve to provide room for the adhesive to fill and also add greater surface area for the epoxy to bond to thehead unit316.
• Thehead316 of theholder302 can be molded from ABS plastic, polycarbonate, nylon, or similar non-magnetic materials Industrial versions can be formed from aluminum as desired. Therotary socket324 can also be formed from similar materials and is configured to include opposing fourmagnets128, one at each quadrant. Themagnets128 strongly attract each other. N42 strength button magnets Ø8 mm×3 mm may have an attracting force of about 2.28 lbs. when spaced about 0.010″ apart. Four of these magnet pairs may provide about 9.12 lbs. of force total. The sliding force of these magnet pairs are approximately ½ of the axial force. Therefore, the resulting magnetic holding force against rotary motion is approximately 4.56 lbs. If themagnets128 are arrayed along a 1.5″ circle, their resulting moment arm is 0.75″. A typical electronic device can be as wide as about 9.5″, or a torque arm of 4.75″. Dividing 4.75 into 0.75 yields a mechanical advantage of about 6.33:1. The resulting force necessary to break away thehead unit316 from its normal position is about 0.72 lbs. or 11.5 ounces when gripping the outside edge of theelectronic device12. The holding strength at the quadrants can be adjusted by magnet size and gap choice. A magnet to magnet attracting force has a self-aligning behavior which may eliminate sloppy positioning when compared to a magnet simply being attracted to a metal target. Since there is about a 9.12 lb. axial force inside the rotary joint326, it might be preferred to have a Teflon™ slip disc364 to eliminate the slip-stick friction between the magnet faces and head and socket surfaces.
• These features noted above may also be applicable to the second and third embodiments of theholder100,200 illustrated inFIGS. 11-15.
• As will be discussed in further detail below, the rotary joint326 between the socket and the heat unit may also include 180-degree end stops106 as provided in previous embodiments (please seeFIG. 29).
• FIG. 27 illustrates a side view of thehead316 of theholder302 with a cut-line to show the rotation limit stop106 for 180 degrees, which is illustrated inFIG. 29.
• As in the second and third embodiments of theholder100,200, the rotary joint326 may be provided with end stops106 for the purpose of using theholder302 itself as the torque arm to tighten or loosen the threadednut322 of the ball andsocket connector318. Without any rotation limits, thenut322 could be difficult to tighten as the rotary joint326 might allow thehead316 of theholder302 to free wheel. The end stops106 can be provided bytabs112 that engage opposingsurfaces114. When a user wants to tighten or loosen theball320 of the ball andsocket connector318, the end stop106 can be engaged to provide the needed torque.FIG. 29 illustrates a cross-sectional view of thehead316, depicting how the end stops106 may be arranged. Therotary socket324 is shown with the cross hatch pattern and shows the fourmagnets128 and fourmagnet pockets162 aligned fully counter clockwise against astop structure115 molded into the headmain body344 at the 9 o'clock position that provides the contact surfaces114. Rotation of thesocket324 clockwise as indicated by the rotation arrow allows therotary socket324 to rotate 180 degrees until theopposite tab112 hits thestop structure115.
• Although in the foregoing description, terms such as “top”, “bottom”, “front”, “back”, “right”, “left”, “upper”, and “lower” may have been used for ease of description and illustration, no restriction is intended by such use of the terms. As discussed previously, the holders/stands and/or the holder systems described herein can be used in any orientation, depending upon the desired application.
• Having described the preferred aspects and embodiments of the present disclosure, modifications and equivalents of the disclosed concepts may readily occur to one skilled in the art. However, it is intended that such modifications and equivalents be included within the scope of the claims which are appended hereto.
