Abstract

A closure is made up of a strap (110, 210, 310, 410, 510, 610) and a holder (130, 230, 330, 430, 530, 630) that engages with the strap while it tightens and loosens, and a retainer (170, 270, 370, 470, 570, 670), which retains the holder in one of the two positions relative to the strap. For items opening lengthwise (e.g., sneakers), the closure includes a lace (795). To unlock the closure, the user moves the holder to the unlocked position. To lock the closure, the user pulls the strap, which automatically moves the closure back to the locked position. The strap has two sets of teeth (112, 114, 212, 214, 312, 314, 412, 414, 512, 514, 612, 614). One set (112, 212, 312, 412, 512, 612), the switching teeth, automatically moves the holder from the unlocked position to the locked position.

Description

BACKGROUND OF THE INVENTION
• 1. Field of the Invention[0001]
• The present invention relates to closures such as ties, fasteners, laces, straps, belts or ropes. More specifically, the present invention relates to a closure which can be used to tie items such as, footwear, garments, packages, cables, orthopedic devices, bandages, sports equipment, seat belts, luggage, plants, etc.[0002]
• 2. Description of the Related Art[0003]
• Current art closures commonly consist of ties made of plastic, VELCRO™, or cord. Closures made of VELCRO™ do not have a strong gripping capability and tend to further lose their gripping strength after repeated usage and laundering. Closures made of cord (such as laces, string or rope) tend to come undone, wear out easily, and the knots and bows are difficult to tie or untie. Current art plastic closures, (such as cable ties) don't have the extensive features and benefits of the present invention. The closures of the present invention overcome the above disadvantages of current art plastic, VELCRO™, and cord closures, and have additional advantages, benefits, and features that no known closures currently have.[0004]
SUMMARY OF THE INVENTION
• The closures of the present invention have benefits that don't exist in any other closures and additionally are extremely simple to use and manufacture, for example by molding. Two basic embodiments are disclosed. A swivel closure and a slide closure. Both the swivel and slide closures may be comprised of as few as two parts and as many as four parts (of course, the closure may be comprised of more than four parts). The four parts are: a strap, holder, retainer, and a lace. The closure, when closing a lengthwise opening (such as a sneaker or corset), includes the lace which is attached to the strap. When the closure totally surrounds an item, the strap could be integral with the retainer and the lace may not be necessary, thus, the closure may have only two parts, (i.e., a strap/retainer and a holder). The closure has uses in many applications and industries. For example, the closure can be used to tie many items. In the footwear field alone, there are many different kinds of articles such as, for example, sneakers, sandals, boots, shoes, slippers, etc. The closure can be used to advantage with simple modifications by someone knowledgeable in the art in almost all instances where VELCRO™, cord, or plastic ties are being used. The closure is released by ratcheting (i.e., expands automatically in discrete increments with pressure from the inside). The closure unlocks with a simple swivel (or slide) of the holder by the user. The closure locks automatically (swivels or slides back to the locked position) when the user pulls on the strap. The strap has a set of locking teeth and a set of switching teeth. The locking teeth engage with a locking member disposed in the holder to lock the closure or tie in discrete ratcheted increments. The locking member may flex vertically (e.g., in the direction indicated by arrow Y in the drawing Figures) to insure a firm hold. The switching teeth engage with a switching member in the holder in two ways, (depending on which end of the strap is being pulled), to perform the following two functions: 1) They permit a loose hold and thus allow discrete ratcheted controlled loosening of the tie (i.e., a ratcheted release). 2) They move the holder from the unlocked position to the locked position when the user pulls on the strap to tighten. The switching member may flex when the tie loosens. When the user pulls on the strap in the direction of arrow C, to tighten, the switching member does not move and engages the holder thereby causing the holder to move (e.g., by swiveling or sliding) within the retainer, thereby automatically moving the holder back to the locked position. Continued pulling on the strap tightens the tie further. Thus, when the user pulls the strap, the tie automatically moves from the unlocked position to the locked position and continues to ratchet tighter and tighter.[0005]
• It is an object of the present invention to provide a closure that will lock and unlock quickly and easily, even when used by the elderly and young children.[0006]
• It is another object of the present invention to provide a closure that will lock automatically when the user pulls on the strap to tighten the closure.[0007]
• It is yet another object of this invention to provide a closure that can be made and assembled easily.[0008]
• It is still yet another object of this invention to provide a closure that can be easily individualized for logos, cartoon characters, sports themes, etc. for use, for example, on sneakers or clothes.[0009]
• It is another object of the present invention to provide a closure that is useful in multiple applications and industries.[0010]
• It is another object of the present invention to provide a closure that can be readily manufactured to attach as an after market accessory. For example, the string can be made to attach into the lace holes, loops or other lace redirection structure of a sneaker or other footwear article.[0011]
• It is another object of the present invention to provide a closure that can be configured to be replaceable and adjustable.[0012]
• It is another object of this invention to provide a closure having a strong and reliable hold so that it can be used where reliability and strength are important, such as, for example, on performance footwear, medical devices, seat belts, sail boats, etc.[0013]
• It is yet another object of the present invention to provide an improved closure whose lace segments constrict a portion of an opening simultaneously and with substantially equal tension, when the user pulls on the strap.[0014]
• It is another object of the present invention to provide a closure whose operation is intuitive to the user.[0015]
• Other objects, features and characteristics of the present invention, as well as methods of operation and functions of the related elements of structure and the combination of parts and the economies of manufacture will become more apparent upon consideration of the following detailed description and the appended claims with reference to the accompanying drawings all of which form a part of the specification, wherein like reference numerals designate corresponding parts in the various figures.[0016]

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EXEMPLARY EMBODIMENTS
• Referring now to FIGS.[0075]1A-5E, a first embodiment of the tie orclosure100 in accordance with the present invention is illustrated.Swivel tie closure100 is comprised of three parts, astrap110, aholder130 and aretainer170.Strap110 has anend116 that is attached (e.g., riveted, sewn, glued, hooked, snapped, etc.) to the item that is to be bound by the closure or to a lace that is to be attached to the bound item. Aholder130, havinglegs134, engages with thestrap110 in one of two positions. Aretainer170 is attached atbore172 to the other side of the item being bound. FIG. 1A shows the tie in the locked position.
• If the user pulls the[0076]strap end118 in the direction of arrow C, the tie will tighten by ratcheted increments. In this orientation, the tie is locked and cannot loosen. To unlock thetie100, the user simply swivels thehandle132 of theholder130 counter-clockwise, in the direction of arrow A, until it stops (approx. ¼ turn). The user unlocks the tie in the conventional counter-clockwise direction (like opening ajar). During this moving or switching of the tie, shown in FIG. 1C, from the locked to the unlocked position, thestrap110 is automatically released from its stowed position underhandle132, throughgap150, due to the force or push from the inside ofhandle180. Handle132 is now parallel to the strap110 (indicating that the tie is unlocked) as shown in FIG. 1B.Strap110, is now free to ratchet open, in the direction of arrow D, when, for example, pressure is applied to the inside of the tie (e.g., when the user steps out of the sneaker). If desired, a more secure lock could be achieved by closing the free end ofclosed gap150. Thus, the holder can not swivel to the unlocked position, until the user removes the strap. Since the strap, which is within theclosed gap150, would block the pivoting movement of the holder.
• FIG. 2 is an exploded view of[0077]holder130 andstrap110 in the locked position as shown in FIG. 1A.Strap110 has lockingteeth114 that engage with aflexible locking member144 onholder130, thereby preventing the tie from opening while permitting the tie to tighten in ratcheted increments.
• The switching[0078]teeth112 simply pass unimpeded through agroove142 formed between oneleg134 and blockingportion136. Thus, switchingteeth112 have no effect onholder130 when the strap is in this locked position. The entire assembly of thestrap110,holder130, andretainer170 is shown in the unlocked position in FIG. 3. In this position, the tie will open or loosen as the switchingteeth112 on top of the strap cause aflexible switching member138 onholder130 to flex. Theflexible switching member138 onholder130 is attached toholder130 atarea139 and has aspace140 underneath, which enables it to flex and is easily molded.
• Locking[0079]teeth114 simply slide over theflexible locking member144 and have no effect, because they are at an angle to each other and cannot engage. Acylinder145 depends downwardly from under theholder130 and snaps into ahole178 in theretainer170 and permits relative rotation betweenholder130 andretainer170. A ridge orflange146 oncylinder145 ensures that theholder130 can not readily be removed from the retainer once placed therein. Aspacer174 is located under theretainer170 to permit the holder to easily swivel.Retainer170 hasopenings182 so that the arms of the retainer can be easily molded from underneath (see FIG. 3). The retainer and strap may be attached at172 and116 to the item to be tied, by rivets, snaps, hooks, glue, or by being sewn. Alternatively, the two ends172 and116 may be integral with each other and thus the retainer and strap can be molded as one piece.
• FIGS.[0080]4A-4D show the detail of thestrap110 and theholder130 in the locked position. When the tie moves through theholder130 in the direction indicated by arrow C, the bottom of the strap controls its' movement and the lockingteeth114 cause theflexible locking member144 to flex vertically, in the direction indicated by arrow Y.
• FIG. 4C shows the bottom of the[0081]strap110 and the bottom of theholder130 which engage in the locked position. If strap10 is moved in the direction of arrow C, one of the lockingteeth114 engages with theflexible locking member144 for ratcheted movement in this direction.
• FIG. 4D shows that the switching[0082]teeth112 simply move through thegroove142 and thus have no effect on the holder in this position.
• FIGS.[0083]5A-5D show the detail of thestrap110 andholder130 in the unlocked position. In the unlocked position, thestrap110 moves in the direction of arrow D, which is opposite to that of arrow C. In this position, the top of the strap controls the movement. FIG. 5C shows switchingteeth112 as they move past theflexible switching member138, causing it to flex horizontally, in the direction of arrow Z, as the strap moves through the holder. The lockingteeth114 simply move past theflexible locking member144, as shown in FIG. 5D. Becauseteeth114 andflexible locking member144 are at an angle with respect to each other they cannot engage in this position. Thus, they have no effect on the movement of the holder.
• The[0084]flexible switching member138 flexes only when in the unlocked position (i.e., when the direction of the pull of the strap is in the direction of arrow D). When the user wants to tighten the tie again FIG. 5E, he simply pulls on the end of thestrap118, in the direction of arrow C (see FIG. 5E). When the pull on thestrap118 is in the direction of arrow C, theflexible switching member138 does not flex, and the next one of the switchingteeth112, engages with thesurface141 of theflexible switching member138. The user's continued pulling on the strap in the direction of arrow C causes theentire holder130 to swivel back to the locked position, clockwise, in the direction of arrow B. This structure simulates a gear, transferring motion from straight to circular. Theflexible switching member138 does not flex because blockingportion136 ofholder130 limits or stops its movement. Therefore, continued pulling on the end of the strap, in the direction of arrow C, causes theentire holder130 to swivel within theretainer170, and thus the holder moves the tie back to the locked position. As the user continues to pull on thestrap118, the tie continues to tighten in ratcheted increments.
• A second embodiment of the closure in the form of a[0085]slide tie200, in accordance with the present invention is illustrated in FIGS.6A-10B.Slide tie200 is analogous to the swivel tie, however the movement required to move the holder from the locked position to the unlocked position (and visa versa) is a sliding movement rather than a swiveling movement.Slide tie200 is comprised of three pieces,strap210, aholder230, and aretainer270.Strap210 has anend216 that is fixedly attached (e.g., riveted, sewn, glued, hooked, snapped, etc.) to the item being bound or attached to a lace or string attached to the bound item.
• [0086]Holder230, hassides234, and engages withstrap210 in one of two positions.Retainer270 is preferably fixedly attached (snapped, glued, hooked, sewn, riveted, etc.) atbore272 to the other side of the item being bound. FIG. 6A shows the tie in the locked position. If the user pulls thestrap end218 in the direction of arrow C, the tie will tighten by ratcheted increments. In this orientation, the tie is locked and cannot loosen. For the user to unlock thetie200, he simply slides theholder230 to the other end of the retainer, in the direction of arrow A, until it stops. In this positions, handle232 is not aligned with the retainer legs280 (indicating that the tie is unlocked) as shown in FIG. 6B. During this switch of the tie, shown in FIG. 6C, thestrap210 is automatically released from under thehandle232, through thegap250, by the push of theretainer legs280.Strap210, will then be free to ratchet open, in the direction of arrow D, when, for example, pressure is applied to the inside of the tie (e.g., when the user steps out of the sneaker). If desired, a more secure lock could be achieved if thegap250 were closed, because the holder could not slide to the unlocked position, until the user first removes the strap fromgap250.
• FIG. 7 is an exploded view of the[0087]holder230 andstrap210 with thestrap210 in the locked position, as shown in FIG. 6A.Strap210 has lockingteeth214 located on the underneath side of the strap. Lockingteeth214 engage with aflexible locking member244 onholder230 and prevent the tie from opening while permitting the tie to tighten in ratcheted increments. Switchingteeth212 simply pass unimpeded through thegroove242 and thus have no effect onholder230 when the strap is in this locked position. The entire assembly of thestrap210,holder230, andretainer270 is shown in FIG. 8 with the tie in the unlocked position.
• In this unlocked position, the tie will loosen as the switching[0088]teeth212 on the strap cause theflexible switching member238 to flex. The flexible switching member is attached toholder230 at thebottom area239 and is easily molded from thebottom space240. Lockingteeth214 slide over theflexible switching member238 and have no effect. Arectangular member245 disposed under the holder snaps into agroove278 in the retainer and permits relative sliding there between. Abeveled ridge246 on therectangular member245 insures that the holder can not readily come out.Spacers274 under theretainer270, permits the holder to slide unimpeded.
• FIGS.[0089]9B-9C show the detail of thestrap210 and theholder230 as it moves from the locked position to the unlocked position. FIG. 9B shows thestrap210 as it is pulled through theholder230 in the direction of arrow C. The lockingteeth214 cause theflexible locking member244 to flex vertically, in the direction indicated by arrow Y. The bottom of thestrap210 and the bottom of theholder230 engage in the locked position. It can also be seen in FIG. 9B that the switchingteeth212 simply move through thegroove242 and thus have no effect in this position. FIG. 9C shows the position of thestrap210 within theholder230 as the user slides theholder230 to the unlocked position, in the direction of arrow A.
• FIGS.[0090]10A-10B show the detail of thestrap210 andholder230 in the unlocked position. In the unlocked position, thestrap210 moves in the direction of arrow D. In this position the switchingteeth212 on the strap control the movement. FIG. 10A shows switchingteeth212 as they move past theflexible switching member238, causing it to flex horizontally, in the direction indicated by arrow Z, as the strap ratchets through the holder to loosen the tie. The lockingteeth214 slide over theflexible switching member238, and have no stopping effect. When the user wants to then tighten the strap again, he pulls on it, as shown in FIG. 10B, in the direction of arrow C, and one of the switchingteeth212, glides along theedge241 of the flexible switching member which is held rigid by theside wall234, causing the holder to slide within the retainer and the strap is automatically switched into the locked position, in the direction of arrow B, where continued pulling on the strap causes it to tighten in discrete increments. This structure simulates a gear, transferring motion from one direction to another. Theedge243 of theflexible locking member244 can be angled for smooth sliding from the unlocked to the locked position (see FIG. 9A).
• FIGS.[0091]11A-11I show an alternate embodiment of the swivel tie in accordance with the present invention. The flexible locking member has twoteeth344 and is integral with theflexible switching member338. Theteeth344 and flexible switching member are one piece.Holder330 has oneleg334, and the strap is not centered within the holder. This embodiment is an example of the large variability inherent in the present invention and the analogous parts. FIG. 11C shows a side view of thestrap310 and theholder330 in the locked position. The flexible locking/switchingmember344 flexes up and down, in the direction indicated by arrow Y, as the strap tightens. FIGS.11D-E are the top views corresponding to FIGS.11B-C. FIGS.11F-G shows the holder and strap in the unlocked position. As the strap moves in the direction of arrow D, the ties is loosened as the switchingteeth312 cause the flexible locking/switching member to flex back and forth, in the directions indicated by double arrow Z, as they move through the holder (i.e., the strap is released by ratcheting). The flexible locking/switchingmember338 is attached to the holder at mountingportion339. When the user wants to lock the tie again, he pulls the strap in the direction of arrow C, and thenext switching tooth312, pushes against thesurface341 of the flexible switching member338 (see FIG. 11I). Sinceflexible switching member338 is prevented from flexing bymember336, the holder automatically swivels or rotates to the locked position, in the direction of arrow B. After which, continued pulling on the strap will tighten the tie even further as shown in FIGS.11D-E. In this embodiment of the swivel tie, theflexible switching member338 extends to the edge of the holder providing increased leverage for the cam gear to turn.
• Referring now to FIGS.[0092]12A-E, another embodiment of theswivel tie400, in accordance with the present invention, is illustrated.Swivel tie400 includes a lockingmember444 that is rigid and a switchingmember438 that flexes vertically (in the direction indicated by double arrow Y).
• FIGS.[0093]12A-12C shows this tie in the locked position. Thehandle432 has a space or groove450 underneath wherestrap410 can be stowed when the tie is in the locked position.
• FIG. 12C shows the strap being tightened by moving in the direction indicated by arrow C. The switching member the[0094]438, may be beveled atsurface443 to smooth the transition from the locked position to the unlocked position (See FIG. 12B). The lockingteeth414 engage with the lockingmember444 to prevent the tie from opening. A part ofholder486 above the lockingtooth444 is widened (see FIGS.12B-C). This widening ofholder430 at486 narrows the entry way of thestrap410, to ensure that the lockingtooth414 and lockingmember444 have a strong grip and the strap cannot pull out. This narrowing could also be accomplished by narrowing the height of the retainer opening. The switchingteeth412 pass unimpeded through achannel442 formed in the holder. FIG. 12D is a cross-sectional view of the holder and strap in the unlocked position showing the switchingteeth412 sliding over theflexible switching member438 as the tie is loosened (i.e., moving in the direction of arrow D). When the user pulls thestrap end418 to tighten it (i.e., in the direction of arrow C) the switchingtooth412 abuts theflexible switching member438 at surface441 (See FIG. 12E). Continued pulling onstrap end418 will result in the tie swiveling back to the locked position.
• FIG. 12F shows an alternate embodiment of the bottom of the holder of FIG. 12B. In FIG. 12F, the switching[0095]member438 is shown as being a part of the bottom of the holder and does not flex. A bottom portion of the holder is cut away to form achannel442 through which the switchingteeth412 move when the tie is being tightened.
• Referring now to FIGS.[0096]13A-13F yet another embodiment of theswivel tie500 in accordance with the present invention is illustrated. Theholder530, in this embodiment has only a top and it is held in theretainer570, by a ridge orprotrusion546 which fits into avertical groove547 during assembly. Thereafter,protrusion546 swivels within an internalhorizontal groove548 inretainer570. The switchingteeth512 on the strap, may be beveled on the inside513, to smooth the transition from the locked position to the unlocked position (see FIG. 13A). The height of the retainer is preferably narrowed, by widening the base ofretainer570 atlocation586 to provide a strong hold when the tie is locked and good contact when the tie automatically swivels from the unlocked to the locked position.
• FIG. 13B shows a top view of[0097]holder530. The relative position of thehandle532, theleg534, theprotrusion546, the lockingmember544, and switchingmember538 are seen (by dotted lines) through the top. FIG. 13C shows the strap being tightened (i.e., by moving in the direction of arrow C) as it moves through the holder.Holder530 has ahandle532, but does not have a space under the handle to stow the strap. Of the various embodiments of the swivel tie disclosed, this is the simplest holder. The holder and strap are shown in the locked position in FIG. 13C.
• FIGS.[0098]13D-E show theholder530 andstrap510 in the unlocked position.Leg534 isopposite protrusion546, and helps maintains the holder in alignment as it swivels from the locked position to the unlocked position within theretainer570.Retainer570 may be attached to an item (e.g., a sneaker, a ski boot, etc.) by a rivet, at, for example,location581.
• FIG. 13F shows an embodiment of the strap whose locking and switching teeth flex, since they have[0099]grooves599.
• Referring now to FIGS.[0100]14A-H still yet another alternate embodiment of theslide tie600 in accordance with the present invention is illustrated.Holder630 has only a top and sides and no handle. The user can slideholder630 from the locked position to the unlocked position by simply pushing on aside wall634 ofholder630. Tworidges646 onretainer670 and the legs of theholder634, as well as thestrap610, maintain the holders assembly as it slides from the locked position to the unlocked position withinretainer670. In this embodiment,strap610 andretainer670 are integral with each other. An example of this tie is shown as a wrist bandage shown in FIG. 16.
• FIGS. 14C shows a top view of the strap and holder in the locked position and FIG. 14D shows the corresponding side view.[0101]
• FIG. 14E shows a top view of the strap and holder in the unlocked position and FIG. 14F shows the corresponding side view. FIG. 14G shows a top view of the strap and holder in the unlocked position about to automatically slide back to the locked position (in the direction indicated by arrow A), when the user pulls[0102]strap end618 in the direction of arrow C.
• FIG. 14H shows the corresponding side view.[0103]
• Referring now to FIGS.[0104]15-15A, the closure includes alace795 which is attached to thestrap710. The lace could be threaded though a hole or holes716 in the strap, hooked into the strap at716, or molded and integral with the strap. This configuration is used for items whose opening is relatively long (such as a sneaker, corset, orthopedic device, etc.).
• Ordinarily, when a user ties his laces, he must pull at each pair of eyelets (holes, loops, hooks, etc.) in succession, for a snug fit. If the sneaker has 4 pairs of eyelets, the user must pull successively at each of the 4 pairs of eyelets to tighten. If he doesn't do this, the top may be tight, while the laces towards the bottom may be loose (i.e., the tension is not evenly distributed). Also, when stepping out of the sneaker, the user must often individually loosen the laces toward the middle and bottom of the sneaker to create room for his foot to be removed.[0105]
• Using the current invention however, a single pull on the strap by the user causes a portion (FIG. 15) or the entire length (FIG. 15A) of the sneaker opening to tighten simultaneously and with equal tension. This provides many benefits for the user, such as, 1) It provides for a better performance sneaker because the tension is equally distributed along the inside of the arch and outside of the foot. 2) It is easier to tie i.e., requires just one pull on the strap, and the sneaker closure is tightened and locked. 3) It is easier to open. . i.e., when the user turns the holder to unlock the closure, the entire length (or a portion) of the sneaker opening loosens simultaneously creating a large opening for the user to step out. 4) The lace will not wear due to the abrasion from tying one's sneakers by knots and bows. 5) It is faster.[0106]
• Specifically, FIG. 15 shows a three piece swivel tie closure attached to the outside of a sneaker. This closure is excellent for runners or triathletes, because it holds as strong as nylon cable ties (which are often used as hand-cuffs because they are so strong), the user can get in and out quickly and easily (important for triathletes), there are no bows or lace ends to loosen or trip over (important for runners), and the tension is distributed evenly along[0107]lace segments791, so the sneaker hugs the foot securely under the length of the arch. Thus, the swivel tie closure when used on a sneaker provides better support, comfort and ease of user for athletes. Alace795 preferably goes through ahole716 in the strap. For example, the lace may form a loop and can be attached to the strap and sneaker in a variety of ways to be both adjustable and replaceable. For example, the two lace ends can form a loop by hooking together, by a hook and eye, or be sewn to each other atlocation793. The lace ends can alternatively be hooked to the sneaker at792, or they can hook into thestrap hole716. The lace in FIG. 15 consists of a single lace loop and is threaded through a single hole in the strap. Twolace segments791 tighten the top portion of the sneaker opening simultaneously, when the strap is pulled.
• The lace in FIG. 15A consists of a single lace loop, and is threaded through two holes in the[0108]strap716. Fourlace segments791 tighten substantially the entire length of the sneaker opening simultaneously, with equal tension, and with one pull. The sneaker opens very wide when the user unlocks the closure so that the user can easily step out. This closure could alternatively have been configured with two (or more) lace loops. After reading the present disclosure as a whole, one skilled in the art can readily contrive of other methods of attaching the lace. The strap and lace of the closure can thus be, adjustable and replaceable. The end of thestrap718 may have a stopper798 (e.g., an enlarged head), to prevent the strap from being pulled out of the holder. The strap may be tucked into a sleeve794 (attached to the sneaker) to keep it close to the sneaker. Alternatively, thestrap end718, could be held to the shoe by Velcro™.
• FIG. 15B shows the three piece swivel tie sewn into a child's sneaker. The ends of the strap and retainer are widened so that there is uniform pull along the entire length of the opening. The handle consists of a tennis ratchet, which the child swivels to unlock the tie, at which time, the strap automatically releases from under the tennis racket. The holders can contain cartoon characters, logos, sports themes, etc. depending upon the desires of the child. The holders can be made to be replaceable with different characters when the child desires (e.g., the holder can snap in and out of the retainer).[0109]
• FIG. 16 shows the two piece slide tie, with no handle, used as an orthopedic device surrounding a wrist. If this closure were to surround a leg, rather than a wrist, it would include a lace, to provide constant tension along the length of the leg.[0110]
• Although this invention has been described generally and in terms of the presently preferred exemplary embodiments, these should not be construed as limiting the scope of the invention. For example, the inside of the holders may be reversed, the locking and unlocking movements may be reversed. The teeth on the straps and within the holder may have different shapes. The locking and switching members in the holder may flex in the same direction, in different directions, or may not flex at all. The locking and switching members disposed in the holder may have multiple teeth. The spacing, shape, height, and angle of the teeth on the strap may be different. There may be only one switching tooth on the strap, in which case, the loosening would be accomplished by friction, or the strap could just loosen freely, without friction. The holders, retainers, handles and teeth etc. may have a different shapes etc. The swivel may be more or less than 90, etc. The laces could form two (or more) lace loops, rather than one, as shown.[0111]
• The switch from a locked position to an unlocked position may be accomplished by other movements, such as push, pull, pinch, lift, etc. The method used to operate the tie is very simple and similar. A) To unlock and loosen the tie. . . the user switches the holder to the unlocked position. B) The lock and tighten the tie . . . . the user pulls on the strap. Thus, the scope of this invention should be determined by the appended claims and their legal equivalents, rather than the examples given.[0112]
• Thus, while there have been shown, described, and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions, substitutions, and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit and scope of the invention. For example, it is expressly intended that all combinations of those elements and/or steps which perform substantially the same function, in substantially the same way, to achieve the same results are within the scope of the invention. Substitutions of elements from one described embodiment to another are also fully intended and contemplated. It is also to be understood that the drawings are not necessarily drawn to scale, but that they are merely conceptual in nature. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.[0113]
