BACKGROUND OF THE INVENTION 1. Field of the Invention
This invention relates to the field of securing items and more specifically to a magnetic spring clip and system for securing items to clothing.
2. Background of the Invention
Items such as writing instruments and flashlights have been secured to clothing by clips. For instance, a conventional writing instrument with a clip includes the writing instrument being retractable into an opening of a barrel and having an operating means including an activation button and an operating cam. Drawbacks to conventional clips used with writing instruments include the writing instrument being operated by a single operating means with the clip only functioning when the writing cartridge is retracted.
Consequently, there is a need for an improved clip and system for securing items such as writing instruments and flashlights to clothing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSFIG. 1 illustratesmagnetic spring clip10 and magneticspring clip system100 for securing instruments to a person's clothing or other objects or devices.FIG. 1 shows an embodiment ofmagnetic spring clip10 implemented oninstrument12. As shown,magnetic spring clip10 is attached toinstrument12. The attachment ofmagnetic spring clip10 toinstrument12 produces opening14 between a portion ofmagnetic spring clip10 andinstrument12.
FIG. 2 shows an exploded view of magneticspring clip system100.Magnetic spring clip10 includesclip base20.Clip base20 may have a semi-circle design such that an opening exists on one side. This opening enablesclip base20 to receive and attach toinstrument22.Clip base20 further includespivot point24 that attachesclip base20 to cliparm26 and enablesclip arm26 to rotate a certain degrees from and towardinstrument22. In some embodiments,clip arm26 is a shaft. The shaft may have any suitable design for use with magneticspring clip system100 such as without limitation a generally linear shape. In some embodiments,clip arm26 may further have a threaded end away from the pivot point end ofclip arm26. Such a threaded end may provide a means to attachclip magnet28 to cliparm26. In other embodiments,clip magnet28 may be a slide on magnet (e.g., slideably engaged with clip arm26). In this embodiment,end cap30 may attach to cliparm26 via such threads to serve as a magnet stop.Second stop32 is also positioned onclip arm26 aboveclip magnet28.End cap30 andsecond stop32 help secure and prevent movement ofclip magnet28. It is to be understood that there may be various types ofinstruments22 to whichmagnetic spring clip10 may be attached such as without limitation generally linearly shaped instruments. One such instrument may be a writing instrument with a magnetic clip as described in U.S. patent application Ser. No. 10/907,734 and another instrument may include a magnetic flashlight such as the flashlight disclosed in U.S. patent application Ser. No. 10/908,108, which are both incorporated by reference herein in their entirety.
It is to be understood that magneticspring clip system100 as shown inFIG. 2 does not reveal the magnet internal toinstrument22. In one embodiment,clip arm26 may be of a magnetic material. Further,surface105 ofinstrument22 may also be of a metal or magnetic material. In such embodiment, the magnetic force ofclip arm26 may causeclip arm26 to be attracted to surface105 ofinstrument22. As shown inFIG. 3, in some embodiments,instrument12 may containinternal magnet34 that is aligned such that the magnetic field ofinternal magnet34 forms an attraction to the magnetic field ofclip magnet28 onclip arm26.
FIGS. 3 and 4 conceptually show the different positions of magneticspring clip system100.FIG. 3 shows magneticspring clip system100 in the closed position. This position is the normal or default position ofmagnetic spring clip10. In this position,clip magnet28 attracts tointernal magnet34. The attraction force (e.g., magnetic attraction) drawsclip magnet28 towardsinternal magnet34 andsurface105. In some instances,clip magnet28 may actually contactsurface105 to provide the clamping action that holds objects inserted into magneticspring clip system100 to secureinstrument12 to the desired object.
FIG. 4 shows the position of magneticspring clip system100 in the open position. In this position,clip arm26 is positioned at a distance frominstrument12. However, because of the magnetic attraction betweenmagnetic spring clip10 andinternal magnet34, a force may be applied to cliparm26 to overcome the magnetic attraction ofclip magnet28 andinternal magnet34 in order to positionclip magnet28 in the open position. In the open position, material to which it is desired to attachinstrument12 is inserted betweeninstrument surface105 andclip arm26. At the release ofclip arm26, the magnetic force may causeclip arm26 to rotate toward and moveclip magnet28 towardinternal magnet34, thereby clamping the inserted material and securinginstrument12 viamagnetic spring clip10 to the material.
FIG. 5ashows a side view of magneticspring clip system100 in the closed position. Magneticspring clip system100 shows an embodiment ofpivot point24. Also shown is an illustration of taperedtop switch40.Switch40 is used to turn on and turn off the light source for a lighting instrument. For a writing instrument, switch40 may advance and retract the writing element of a writing instrument.
FIG. 5bis a side cross-sectional view of magneticspring clip system100. This embodiment is one in whichmagnetic spring clip10 is attached toinstrument12, which is in this embodiment a lighting instrument. In addition to the elements of magneticspring clip system100, contained withininstrument12 is a pair ofbatteries42 and44.Internal magnet34 is positioned betweenbatteries42,44. At the lower end ofinstrument12 islight bulb46.Switch40 may be a rotating switch as shown or a push switch. In the implementation of magneticspring clip system100 as illustrated inFIG. 5b,internal magnet34 may not interfere with operation ofbatteries42,44 or electrical functions ofinstrument12.
FIG. 6ais a side view of the pivot mechanism ofmagnetic spring clip10. In the pivot point mechanism,pivot rod48 extends throughclip arm26 and attaches towalls300 ofclip base20.Clip arm26 may be positioned inclip base20 to provide greater flexibility and degrees forpositioning clip arm26 in the open position. Extension of portions ofclip arm26 towardswitch40 may restrict the degrees of the opening position. InFIG. 6b,the amount ofspace50 betweenclip base20 andclip arm26 also allows for the limited movement ofclip arm26. Thecloser clip arm26 is to the top ofclip base20, the smaller the movement ofclip arm26. As shown inFIG. 6b,clip base20 has walls300 (e.g., a wall on each side),upper side305, andopening310 suitable for receiving clip arm26 (e.g., shaft).
FIG. 7 is a side view of an embodiment of magneticspring clip system100 withinstrument12, which as illustrated is an illuminated writing instrument. In this embodiment, magneticspring clip system100 is implemented in an improvedilluminated writing instrument12, which includes writingelement60,lighting element62 and attachingelement64.Lighting element62 containsinternal magnet66.Clip magnet28 magnetically attracts toinstrument12. Writingelement60 andlighting element62 are secured to each other via attachingelement64. A suitable attaching element is disclosed in U.S. patent application Ser. No. 11/112,260, which is incorporated by reference herein in its entirety. Writingelement60 andlighting element62 are secured to each other through openings in attachingelement64. Attachingelement64 has an exterior surface formed of elastic grippers that provide increased stability between the user and the writing instrument. Attachingelement64 also has the capability to alter its shape in response to pressure from a user's fingers. The capability to alter the shape of attachingelement64 enables the user to easily and comfortably holdinstrument12.
FIG. 8 is a side view of an alternate embodiment of magneticspring clip system100 implemented withinstrument12, which in this embodiment is an illuminated writing instrument. In this embodiment, magnetspring clip system100 is implemented ininstrument12 that includes writingelement80,lighting element82, and attachingelement84. Writingelement80 andlighting element82 are secured to each other via attachingelement84, which is disclosed in U.S. Pat. No. 7,101,103. U.S. Pat. No. 7,101,103 is incorporated by reference herein in its entirety. Attachingelement84 is a combination dual clip that attaches writingelement80 andlighting element82 such that the twoelements80,82 form oneilluminated writing instrument12. Magneticspring clip system100 further includesmagnetic spring clip10 to secureinstrument12 as desired by the user. In operation, the force from the magnetic field ofclip magnet28 attracts to the internal magnet (not illustrated) inlighting element82. This attraction may drawclip magnet28 to the internal magnet. The attachment ofclip magnet28 and the internal magnet may secureclip arm26 to the internal magnet thereby creating the mechanism that may provide the securing capabilities ofmagnetic spring clip10.Magnetic spring clip10 may have the capability of securinginstrument12 as desired by the user. In alternative embodiments (not illustrated), attachingelement84 is a rubber grummet.
FIG. 9 is a side view of an alternate embodiment of magneticspring clip system100 attached to attachingelement84, which is a dual clip.Clip base20 attaches to attachingelement84. In operation, the force from the magnetic field ofclip magnet28 attracts to the internal magnet (not illustrated) ininstrument12. Such attraction may drawclip magnet28 to the internal magnet. In this embodiment,clip arm26 extends over attachingelement84.
FIG. 10 illustratesclip magnet28 andinternal magnet34, which are each magnetized to have north and south poles. In an embodiment,internal magnet34 hasnorth pole200 andsouth pole205, andclip magnet28 has clipmagnet north pole210 and clipmagnet south pole215.Internal magnet34 is rotatable about its longitudinal axis withininstrument12 but is substantially fixed about the longitudinal axis ofinstrument12. In such an embodiment,clip magnet28 is not rotatable about its longitudinal axis but has instead been attached tomagnetic spring clip10 with clipmagnet north pole210 distal toinstrument12 and clipmagnet south pole215 proximate toinstrument12. In such an embodiment, whenmagnetic spring clip10 is in the closed position as shown inFIG. 10, the magnetic attraction of clipmagnet south pole215 attractsnorth pole200, andinternal magnet34 rotates about its longitudinal axis untilnorth pole200 is proximate to clipmagnet south pole215. Therefore,north pole200 is distal to the body of the individual, for instance wheninstrument12 is placed in a pocket of the individual and secured to the pocket bymagnetic spring clip10. Without being limited by theory, placingnorth pole200 distal to the individual's body may prevent detrimental health issues to the individual that may be related to magnetic fields. For example, without being limited by theory, placingnorth pole200 proximate to the individual's body may restrict blood flow in vessels exposed to the magnetic field exerted bynorth pole200, which may be a detrimental health effect. Such restriction may not occur withsouth pole205 proximate to the body. In alternative embodiments,internal magnet34 is not longitudinally rotatable but is instead fixed in position withininstrument12, withnorth pole200 proximate to clipmagnet south pole215. In alternative embodiments (not illustrated),magnetic spring clip10 further includes a shield. The shield may be composed of any material suitable for shielding a magnetic field. Without limitation, an example of such material is ferrous metal. The shield is disposed about a portion of the outside ofclip magnet28. In an embodiment, the shield is disposed about a portion of the outside ofclip magnet28 that does not include the portion ofclip magnet28 that is in contact withinstrument12 whenclip magnet28 is in the closed position. The shield may be disposed about the outside ofclip magnet28 by any suitable method. For instance, the shield may be applied as a coating, manufactured to be disposed about the outside ofclip magnet28, and the like. In such embodiments, the shield may provide a shield against at least a portion of the magnetic field of bothclip magnet28 andinternal magnet34. In some embodiments,instrument12 may also include such a shield about a portion ofsurface105. In such embodiments, the shield may leave exposed at least a portion or substantially all of the portion ofsurface105 that is a contact point withclip magnet28. In embodiments, the shield may provide a shield against at least a portion of the magnetic field of bothclip magnet28 andinternal magnet34.
Although the present invention and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations may be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
