DETAIL DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(19) With reference now to the drawings, and in particular to FIGS. 1 through 18D, embodiments of a fastener pull apparatus 10 embodying the principles and concepts of the present invention will be described.

(20) FIGS. 1-4 show various views of a housing 12 in which the fastener pull apparatus 10 is arranged. The housing 12 is incorporated as part of a decorative element. It is noted that although, shown in the figures, the housing 12 is incorporated into a male figurine, the housing 12 should not be limited to being part of said figurine and can be part of a female figurine, an object, an animal, a character, a shape, etc.

(21) In general, the fastener pull apparatus 10 is a spring-loaded, ratcheting, winding mechanism that allows for the extension and retraction of a cord 14. In an embodiment, a clasp 15 can be fixed to the cord 14 external of the housing 12. The cord 14 can be freely pulled out of the housing 12 and retracted therein by partially depressing a button 34 (i.e., up to about of a possible travel distance of the button 34). If the button 34 is depressed fully, the cord 14 can be precluded from extending from retracting within the housing 12. It is noted that the cord 14 can extend through a tube 13 (see FIG. 2) that can be fixable to the housing 12.

(22) As will be described in detail below and can be seen, for example, in FIGS. 5-8, the fastener pull apparatus 10 includes a plurality of elements that work together to allow for the releasable extension and retraction of a cord 14 through an opening 13 in the housing 12. These elements include a front housing 16, a shaft 18 that extends from an inner surface 20 of the front housing member 16, a flat coil or clock spring 22, a first coil spring 24, a spool 26, a retractable button 28, a spool plate 30, a second coil spring 32, a cap 34 and a rear housing member 36 that includes an opening 41 to allow the cap 34 to extend therethrough.

(23) As illustrated, for example, in FIGS. 9 and 10, the front housing 16 includes a sidewall 40 that extends from the rear side 42 thereof and is configured to substantially retain many elements of the fastener pull apparatus 10 therein in an assembled state. The shaft 18, which is centrally located within the sidewall 40, extends directly from the rear of the front housing 16. The shaft 18 includes a base 44, a first projection 46 that extends from the base 44 and a second projection 48 that is spaced from the first projection 46 such that a gap 50 exists between the first and second projections 46, 48 and extends from the base 44. The first projection 46 and the second projection 48 each include a groove 52, 54, respectively. As can be seen in FIG. 9, a channel 56 extends along the base 44 between the first and second projections 46, 48 to aid in securing a first end 58 of the flat coil or clock spring 22 within the housing 12. As shown in FIGS. 9 and 10, the shaft 18, the sidewall 40 and the front housing member 16 are a one-piece molded element. However, it is contemplated that at least some of these elements of the fastening pull apparatus 10 can be independent elements of each other.

(24) FIGS. 11-13 depict the rear housing 36. The rear housing 36 includes an opening 41 that extends therethrough and a sidewall 43 that extends from a rear side 45 thereof. The sidewall 43 is substantially cylindrical and includes a plurality of channels 47 that are spaced from each other. The channels 47 are configured to interact with tabs 120 that protrude from the cap 34 to aid in positioning the cap 34 in relation to the other elements of the fastener pull apparatus 10 and to preclude the cap 34 from rotating. If the cap 34 was permitted to rotate within the rear housing 36, the cap 34 together with the spool plate 30 would not be capable of preventing the cord 14 from retracting, if desired. As shown in FIGS. 11 and 12, the rear housing 36 and the sidewall 43 are a one-piece molded element. However, it is contemplated that these elements can be independent elements of each other.

(25) FIGS. 14A-14D depict various views of the spool 26. The spool 26 includes a cylindrical body 60 that has an outer surface 62 around which the cord 14 can be wound, an inner surface 64 opposing the outer surface 62, a first rim 66 extending in a first direction from and delimiting a first end of the spool 26, a second rim 68 extending in the first direction from and delimiting a second end of the spool 26 and a wall 70 that has a hole 72 through which the shaft 18 projects, extending at approximately a midpoint of the inner surface 64 of the spool 26 and that separates the space within the spool 26 into a first cavity 74 and a second cavity 76. The spool 26 further includes a plurality of slits 78 to aid in securing a second end 59 of the flat coil or clock spring 22 and a plurality of recesses 80 that, as will be discussed below, are configured to interact with and secure the spool plate 30 to the spool 26. As shown in FIG. 5, the flat coil or clock spring 22 is arranged or nested within the first cavity 74 of the spool 26 and the retracting button 28 is arranged within the second cavity 76 of the spool 26.

(26) The shaft spring 24, as depicted, for example, in FIGS. 5 and 7-9 is sized and configured to be arranged within the gap 50 located between the first projection 46 and second projection 48 of the shaft 18, positionable within the gap 50 by the grooves 52, 54 of the first and second projection, respectively, and contactable with the flat coil or clock spring 22, contactable at a first end with the base 44 of the shaft 18 and contactable at a second end with the wall 70 of the spool 26 that divides the inner area of the spool 26 into the first cavity 74 and the second cavity 76.

(27) FIGS. 15A-15F show various views of the retracting button 28, which is configured to be arranged in an assembled state in the second cavity 76 of the spool 26 (see FIG. 5). The retracting button 28 generally includes a hub 82 and a flange 84 that extends about the outer periphery of the hub 82. The hub 82 includes a first slotted opening 86 and a second slotted opening 88 that is spaced from the first slotted opening 86 extending through a first surface 90 of the hub 82 and a substantially square shaped opening 92 extending through a second surface 93 of the hub 82. The shape of the substantially square shaped opening 92 can vary such that the corners of the opening 92 are rounded. The substantially square shaped opening 92 and the first and second slotted openings 86, 88 are configured to interact with the shaft 18 and the first and second projection 46, 48 such that the shaft 18 and projections 46, 48 can extend through the opening 92 and the first projection 46 can extend through one of the first slotted opening 86 or the second slotted opening 88 and the second projection 48 can extend through the other of the first slotted opening 86 or the second slotted opening 88. In an assembled state, the shaft 18 and in turn projections 46, 48 cannot rotate within the square shaped opening 92, the first slotted opening 86 or the second slotted opening 88.

(28) The flange 84 includes a plurality of ramps or teeth 94 that extend about a first surface 96 of the flange 84. As will be described in more detail below, the ramps or teeth 94 of the retracting button 28 are configured to releasably engage mating ramps or teeth 98 of the spool plate 30.

(29) As depicted in FIGS. 16A-16F, the spool plate 30 includes a disk-shaped housing 100 that has a first surface 102 and a second surface 104 and an opening 106 through which the shaft 18 can extend in an assembled state. A plurality of tabs 108, which are spaced from each other, extend from the first surface 102 at an outer periphery thereof. The tabs 108 are configured to interact with the plurality of recesses 80 formed in the first rim 66 of the spool 26 to fix the spool plate spool plate 30 to the spool 26 and secure the retracting button 28 between the spool 26 and the spool plate 30. As show in FIG. 16B, a plurality of tabs or stops 112 extend from the second surface 104.

(30) FIGS. 17A-17E illustrate various views of the cap 34. The cap 34 includes a pot-shaped housing 114 forming a cavity 116 therein, a flange 118 that extends from the open end of the housing 114, a plurality of tabs 120 that extend from the an outer periphery of the flange 118 and at least one projection or stop 122 that extends from the flange 118 and is configured to interact with the tabs 112 of the spool plate 30 when the cap 34 is depressed more than of the total possible travel of the cap 34 toward the front housing 16 to preclude retraction or extension of the cord 14. The at least one projection 122 is arranged to be located between two of the tabs 112 of the spool plate 30 when the cap 34 contacts the spool plate 30. Because the spool plate 30 is fixed to the spool 26, when the at least one stop 122 contacts one of the tabs 112 of the spool plate 30, the stop 112 indirectly precludes rotation of the spool 26 and in turn prevents the cord 14 from extending or retracting from the figurine 12. Although one stop 122 is shown, the cap 34 can include a plurality of stops 122 that can be interspersed between the tabs 112. The cap 34 further includes a post 124 about which the shaft spring 24 can be arranged in an assembled state.

(31) FIGS. 18A-18D are directed to an embodiment of the clasp 15. As shown, the claps 15 includes a first arm 17, a second arm 19 that is rotatable with respect to the first arm 17 and a third arm 21 that is rotatable with respect to the first arm 17 and the second arm 19. The first arm 17 includes a first surface 23 and the second arm 19 includes a second surface 25 that opposes the first surface 23. In use, an object, such as a pull-tab of a zipper, is placed between the first surface 23 and the second surface 25 and the third arm 21 is configured to releasably secure the first arm 17 and second arm 19 to each other and the object (e.g., pull-tab) between the surfaces 23, 25. A hook 27 is attached to the clasp 15 and is contactable to the cord 14. The apparatus 10 can be pulled user in the direction desired. For a dress that includes a zipper, the pull-tab is grasped by the clasp 15 and pulled such that the zipper slider moves in a direction to join the teeth that extend from each side of a zipper tape, sealing the zipper. The pull-tab can then be released from the clasp 15.

(32) In operation, an individual can grasp the housing 12 in one hand and the cord 14 and/or the clasp 15 in the other and pull on the cord 14 and/or clasp 15 to extend the cord 14 out of the housing 12. This in turn simultaneously causes the spool 26 to rotate and the flat coil or clock spring 22 to wind and contract, and increase tension on the fastener pull apparatus 10. The tensioning of the system 10 precludes the cord 14 from being freely retracted after being extended from the housing 12. The cord 14 is only permitted to extend from the housing 12 if the cap 34 is not depressed because the shaft spring 24, which is arranged within the cavity 50 of the shaft 18, is configured to abut the second surface 93 of the retracting button 28, applying pressure thereto which keeps the ramps or teeth 110 of the button 28 engaged with the ramps or teeth 94 of the spool plate 30. Because the spool plate 30 is fixed to the spool 26, by keeping the ramps or teeth 94, 110 engaged with each other, the spool 26 is prevented from rotating and as such, the clock spring 22 is precluded from expanding to a rest state and rewinding the cord 14 about the spool 26. Additionally, it is noted that the retraction button 28 is precluded from rotation by the shaft 16 due to geometry of the features of the retraction button 28 and the shaft 16. As noted above, the retraction button 28 first slotted opening 86 and a second slotted opening 88 and a substantially square shaped opening 92 extending through a second surface 93. When the shaft 16 is arranged within the openings 86, 88, 92, due to the rectangular shape of the openings 86, 88 in the hub 82 and the square shaped opening 92, the retraction button 28 is precluded from rotation about the shaft 16.

(33) To retract the cord 14, the cap 34 must be depressed. The cord 14 will retract as the cap 34 is depressed and travels up to about of its total possible travel distance along an axis of the apparatus 10. The cord 14 is able to retract upon partial depression of the cap 34 because the second spring 32 has a higher spring rate that the first spring 24 and as such, is able to overcome the spring force of the first spring 24, compressing the first spring 24 and in turn permitting the ramps or teeth 94 of retraction plate 28 to become disengaged from the ramps or teeth 110 of the spool plate 30 (i.e., the retraction plate 28 can move about the second cavity 76 of the spool 26). By disengaging the connection between the ramps or teeth 94, 110, the spool plate 30 no longer restricts rotation of the spool 26 to which the spool plate 30 is fixed, allowing the tension placed on the flat coil or clock spring 22 to be released and the spool 26 to rotate and wind the cord 14 about the sidewall 60 thereof.

(34) If the cap 34 is depressed beyond of the total possible travel distance along the axis of the apparatus 10, the retraction button 28 stops traveling away from the spool plate 28 (i.e., it bottoms out against the wall 70 of the spool) and the second spring 32 begins to compress. The cap 34 continues to travel toward the front housing member 16. The stop 122 of the cap 34 contacts the spool plate 30, between two of the projections 112 of the spool plate 30 and contacts one of the projections 122 which prevents rotation of the spool 26 in either direction and in turn the cord 14 will be prevented from being extended from the housing 12 or being retracted therein.

(35) Although the description above and accompanying drawings contains much specificity, the details provided should not be construed as limiting the scope of the embodiments, but merely as describing some of the features of the embodiments. The description and figures should not to be taken as restrictive and are understood as broad and general teachings in accordance with the present invention.
