Description

FIELD OF THE INVENTION

The present invention generally relates to zip fasteners, and more particularly to zipper sliders and closures for one handed operation of zip fasteners.

BACKGROUND OF THE INVENTION

Zip fasteners are commonly used to fasten portions of fabric or other flexible material. A typical use for zippers is to fasten two adjacent fabric portions along their edges where both ends of either portion are unconnected to the other's, as in the case of the front of a garment such as a coat or jacket. When closing a garment using known zipper fasteners on the front of a garment, the wearer must locate a zipper closure at the bottom of the garment and couple a small insertion pin on one side of the zipper to a retaining box on the opposite side of the zipper. The size of the pin and retaining box and the direction of the insertion process often makes it difficult to quickly couple the two parts. This is especially true when the garment is bulky, such as a winter coat, or when the wearer is wearing gloves. More importantly, this is also problematic for people who suffer from disabilities in their upper limbs, for children, and the elderly. It is also difficult for someone to help the wearer as the natural position of the hands when trying to close the zipper is reversed. Moreover, the need to position the pin and retaining box to be accessible to both hands and, again, the direction of insertion impose significant limits on the design potential of products that incorporate zippers.

In view of the foregoing, it would be advantageous to provide a zipper fastener that is more easily opened and closed by the wearer, even if the zipper is provided on a bulky object of manufacture or in less accessible positions than in current designs. It would also be advantageous to provide a method of manufacturing a zipper fastener that provides the aforementioned advantages.

SUMMARY OF THE INVENTION

There is an object of the invention to provide a zipper fastener suitable for one-handed operation.

A zipper fastener is configured to fasten a first fabric portion to a second fabric portion. The zipper fastener comprises a plurality of first zipper elements positioned along the first fabric portion and a plurality of second zipper elements positioned along the second fabric portion. The zipper fastener further includes a split slider comprising a first slider member releasably coupleable to a second slider member. The first slider member and the second slider member engage the plurality of the first zipper elements and the plurality of second zipper elements, respectively. The zipper fastener further includes a zipper closure comprising a first closure member releasably coupleable to a second closure member. The first closure member and the second closure member are positioned on the first fabric portion and the second fabric portion, respectively, such that the two closure members may be coupled by applying a force to them perpendicular to the surface of the fabric portions.

The zipper fastener may be configured in numerous different embodiments and for numerous different applications. For example, in at least one embodiment, the first closure member and the second closure member are configured to be mechanically coupled using a snap lock mechanism. Furthermore, in at least one embodiment, the first slider member and the second slider member are configured to be mechanically coupled using a quick release pin.

DETAILED DESCRIPTION

With reference to FIG. 1A, a prior art zipper 01 is shown to have a first and second tapes 011, a slider 012, a plurality of teeth 014 on each of the tapes 011, a box 016 on the first tape, and a pin 015 on the second tape. The slider 012, shown in detail in FIG. 1B, comprises a puller 013, a body 017, and a crown 019. The zipper 01 and its method of operation, the way it closes or opens in order to fasten or separate the two tapes are well known to those of ordinary skill in the art, as are the difficulty that its structure and method of operation present to many people.

We found that a novel split slider design, splitting the slider into a male and a female members, and providing a parallelly configured male and female closure members to replace the pin 015 and box 016 of the prior art, eliminates the difficulty of inserting the pin into the box. FIG. 2 shows a male slider member 211 that is releasably coupleable to a female slider member 212 to form a split slider 21, shown later in assembled form in FIG. 5B. The male slider member 211 shown in FIG. 2, also shown in FIGS. 3A and 3B from different perspectives, comprises a body 2171, a crown 219, and a quick release mechanism 220. In this embodiment, the said mechanism is a quick release pin having two spring loaded balls 221, a shaft 223, and a spring loaded button 225. The male slider member 211 slideably couples with the female slider member 212 of FIGS. 2, 4A and 4B. The female member comprises a tapered cavity 222 that matches the shaft 223, such that when the shaft 223 is seated into the cavity 222 of the female member 212, the balls 221 may be seated into the holes 224 and the male and female slider members are coupled. The balls 221 are configured to have an initial deployed position wherein they project out of the shaft. The tapering of the shaft 223 and cavity 222 facilitates the insertion of the shaft 223 into cavity 222 and allows the coupling of the male and female slider members using a simple push-to-close operation of the quick release mechanism 220, wherein the balls 221 are forced inside the shaft 223 gradually, until they are in a position to lock into corresponding holes 224 of the female member 212 when the spring action pushes them back to their deployed position, locking the two members together.

Advantageously, the male slider member 211 of FIG. 3B and female slider member 212 of FIG. 4B can be coupled by inserting the male member using a force perpendicular to the surface of the tapes 011 of the zipper, the advantage becoming evident when describing the male and female zipper assemblies of FIG. 7A and FIG. 7B. FIGS. 5A and 5B show a front view and a perspective view, respectively, of a split slider assembly 21 comprising the male slider member 211 of FIG. 3B coupled to the female slider member 212 of FIG. 4B.

In addition, the male slider member 211 comprises a puller 213 that is configured to rotate around the axis of a cylindrical cavity 2191 of the crown 219. The puller 213 further features a finger 2131 that, when the puller is rotated more towards the quick release mechanism 220 from its position shown in FIGS. 3A and 3B, it causes its finger 2131 to depress the button 225, in turn causing the spring loaded balls 221 to be retracted to release the male slider member 211. Rotating the puller 213 away from the button 225 causes the spring loaded balls to return to their initial deployed position.

FIG. 6 shows a perspective view of a male closure member 511 that is releasably coupleable to a female closure member 512 of a zipper closure 51 in accordance with one embodiment of the present invention. In this embodiment, the male closure member 511 comprises a male snap lock feature 513 that couples with a female snap lock feature 514 of the female closure member 512.

Now referring to FIG. 7A, a male zipper assembly 1215 comprises a zipper tape 011, the male closure member 511 securely attached to the zipper tape 011, and the male slider member 211 that engages the zipper elements of the tape 011. Analogously, referring to FIG. 7B, a female zipper assembly 1216 comprises a zipper tape 011, the female closure member 512 securely attached to the zipper tape 011, and the female slider member 212 that engages the zipper elements of the tape 011. A user may use a force perpendicular to the zipper tapes 011 to couple the male slider member 211 to the female slider member 212 and the male closure member 511 to the female closure member 512, and thus couple the said male and female zipper assemblies.

FIG. 8A shows a side view of a zipper 02 in accordance with the present invention. The same zipper assemblies of FIG. 7A and FIG. 7B are shown, with the male zipper assembly 1215 in position over but separate from the female zipper assembly 1216. The two assemblies are configured such that when the male slider member 211 is above the female slider member 212, the male closure member 511 is above the female closure member 512. The puller 213 is shown in a flat position but it could be held by a user in a different position to handle the male zipper assembly 1215 and align the male slider and male closure members over their male counterparts of the female zipper assembly 1216. The user may then push the said male members into the said female members, coupling the said assemblies together to yield the zipper 02 in a coupled state, as shown in FIG. 8B.

FIG. 9 shows a perspective view of a partially closed zipper 02 in accordance with the present invention. In this figure, the puller 213 is rotated to a position that allows a user to slide the split slider 21, causing the teeth of the slider tapes 011 to engage in the same manner known in the prior art. In order to keep the said slider from separating into its male and female members, the puller 213 is not rotated by more than 90 degrees from its flat position shown in FIGS. 8A and 8B, and the user can slide it farther in the direction indicated by the dashed arrow to close the zipper 02 over its entire length. To open the closed zipper 02, a user may use the puller 213 to slide the slider 21 in the direction of the zipper closure 51, causing the zipper teeth on the tapes 011 to disengage in the same manner known in the prior art.

FIG. 10 shows a perspective view of a separated zipper 02 in accordance with the present invention. The dashed curved arrow in FIG. 10 depicts the user applied force to rotate the puller 213 past a 90 degrees angle from its flat position which causes the finger 2131 to depress the quick release button 225 and the male slider member 211 to separate from the female slider member 212. With the said slider members separated, the last engaged zipper teeth on the tapes 011 disengage easily by pulling the said tapes apart, and the disengagement proceeds progressively over the length of the closed segment of the zipper. The user may then pull apart the snap lock of the male closure member 511 and female closure member 512 to open the zipper completely.

In accordance with one embodiment of the present invention, FIG. 11 shows a split slider 21a comprising a male slider member 211a that is releasably coupleable to a female slider member 212a. The male slider member 211a comprises a body 2171a, a crown 219a, and a snap joint 227 comprising an arm 2273 and a hook component 2271. The snap joint 227 further comprises a cavity with an undercut feature 2272 which mates with the hook component 2271, and is integral to the female slider member 212a. The female slider member 212a comprises a body 2172a wherein the cavity 2272 is made. A user may align and slide the male slider member 211a against the female slider member 212a to cause the hook 2271 to catch in the undercut of the cavity 2272 and couple the male and female slider members. The snap joint 227 may be implemented as a torsion snap joint, known to those with ordinary skill in the art, with a torsion bar (not shown) whose axis is indicated by the dashed line and made integral to the crown 219a of the male slider member 211a. During the joining of the male and female slider members, the hook component 2271 is configured to deflect briefly as it slides into the cavity 2272 and catches in the undercut of the said cavity. To separate the male and female slider members, a user may apply a force P to the top of the hook component 2271 (shown with a straight arrow) to rotate the torsion bar and allow the end of the hook component 2271 to move out of the undercut of the cavity 2272, thus separating the male and female slider members 211a and 212a. FIG. 12 illustrates the position of the snap joint 227 during a joining or separating operation, just before it catches or clears the undercut in the cavity 2272.

FIG. 13 shows a perspective view of the split slider 21a using a cantilever snap joint instead of a torsion snap joint. In this configuration, a user may slide the male slider member 211a against the female slider member 212a using the puller 213a to join or separate the two members. As the hook component 2271 (not shown) enters the cavity 2272, the arm 2273 deflects to allow the hook to catch or clear the undercut in the said cavity. The hook 2271 and undercut of the cavity 2272 are configured differently in this cantilever snap joint from the torsion snap joint configuration described earlier, and both of these configurations are known to those of ordinary skill in the art.

FIG. 14 shows a perspective view of the split slider 21a of FIG. 11 with the female slider member 212a coupled to male slider member 211a.

FIG. 15 through FIG. 20 show different views of an alternative embodiment of a split slider in accordance with the present invention. In these figures, the different features of the male slider member 211a and the female slider member 212a have the same labels of similar features shown in earlier figures, namely the crown 219a, the body 2171a of the male slider member, the body 2172a of the female slider member, the cavity 2272 of the female slider member, and the hook 2271 and the arm 2273 of the male slider member.

In this embodiment, The male slider member 211a in FIG. 15 through FIG. 20 comprises an additional arm 2371 that may be inserted into a matching cavity 2372 of the female slider member 212a of the same figures. In mirror fashion, the female slider member 212a in FIG. 15 through FIG. 20 comprises an additional arm 2472 that inserts into a matching cavity 2471 of the male slider member 211a.

While the foregoing provides a few embodiments of the zipper slider 21 and zipper closure 51 for the zipper fastener 02, it will be recognized that numerous other alternative embodiments for the zipper fastener are possible, including additional alternative embodiments that relate to the zipper slider 21 and 21a and zipper closure 51 and other portions of the zipper fastener. For example, in one alternative embodiment, the zipper closure 51 may be configured using a snap button, a snap joint, or a quick release fastener instead of the snap lock of the male closure member 511 and female closure member 512 used in this description. In another alternative embodiment, the split slider 21 may be configured using a quarter-turn fastener instead of the quick release pin or snap joint mechanisms described above, providing a push-to-close, turn-to-open operation of coupling and decoupling the male and female slider members. In such an alternative embodiment, the male slider member comprises a fastener stud connected to a puller that a user can push to engage and turn to disengage the fastener stud from a corresponding receptacle on the female slider member. In yet other embodiments, the male and female slider members may be configured to have additional jointing features in order to provide rigidity to the split slider assembly.

Other examples of alternative embodiments of the zipper fastener relate to the orientation of the coupling of the slider members and the closure members. While the puller remains perpendicular to the surface of the tape, the coupling mechanism of the split slider members may be configured to have a transverse orientation across the width of the zipper tape, and correspondingly, the coupling mechanism of the closure members may then have a transverse orientation. In such embodiments, the force that a user applies to couple different members may be parallel to the surface of the fabric portions and perpendicular to the orientation of the zipper chain.

Other examples of alternative embodiments of the zipper fastener 02 relate to the configuration of the zipper tapes 011. For example, teeth connected to the tapes may be individual teeth, a zipper coil may be provided, as will be recognized by those of skill in the art. Moreover, the teeth may be configured differently to provide different features. For example, the zipper tapes may be configured to add a tactile feel or other sensory feedback such as a unique sound as the split slider moves along the tape. In addition, the teeth may have a unique shape or configuration to provide a unique look and feel to the zipper fastener. Furthermore, while teeth may have a particular shape to provide the quick release feature, different shaped teeth are possible, including different shaped teeth for the quick release feature or teeth that do not provide for the quick release feature, thus forcing the user to un-zip the zipper fastener in order to open the garment.

In yet other embodiments of the zipper fastener, the split slider may be configured to provide anti-jamming or anti-snag features that prevent fabric from getting caught in the sliders. The split slider members and zipper closure members may include additional features that assist the user in aligning the slider members and the closure members. For example, the slider members and the closure members may be configured with magnets of such polarities that facilitate their alignment as described herein, thus assisting the user in joining the male and female zipper assemblies and starting the zipping process. Additionally, the puller on the male slider member may be a locking or non-locking puller.
