DETAILED DESCRIPTION
(19) The present disclosure relates to a zipper locking device 10 having an anchor 12 and a releasable lock 21. The device 10 is adapted to secure a zippered closure 4, for example, a bag having a zippered compartment with a cavity C.
(20) The anchor 12 is configured to be releasably mounted onto a portion of the zipper track and zipper tape of the zippered closure 4. In some embodiments, the anchor 12 includes a clamp 14. The clamp 14 may be a U-shaped clamp, as seen in
(21) In one embodiment, the clamp may include contact surfaces so as to increase the frictional engagement of a portion of the zipper track 6 of the zippered closure 4 by the clamp 14. For example, the clamp may include an upper contact surface 18a and a lower contact surface 16a, both surfaces adjacent to the portion of the zipper track 6 being engaged. The upper 18a and lower 16a contact surfaces may be interlocking, as seen in
(22) The upper and lower portions, 18, 16 of the clamp 14 may be compressed towards each other by mechanisms as are known to a person skilled in the art, including but not limited to worm or screw drives, springs, spring clips and rotating cam levers. In some embodiments, the upper and lower portions 18, 16 of the clamp 14 are compressed together with a clip 20, as shown for example in
(23) Clip 20 compresses clamp 14 so as to increase the engagement between the clamp 14 and a portion of at least the zipper track 6. In one embodiment, the clip 20 may be a rigid, U-shaped clip. Clip 20 may be slidably mounted onto clamp 14 and is slideable between a locked position and an unlocked position. In the unlocked position, the clamp 14 is not compressed by clip 20, so as to widen gap G for ease of installing the clamp 14 onto the zipper track 6 or removing the clamp 14 from zipper track 6. In the locked position, clip 20 is compressing the clamp 14, so as to urge contact surface 16a towards contact surface 18a, thereby narrowing the gap G, and increasing the frictional engagement between contact surfaces 16a, 18a and the portion of the zipper track 6 that is gripped therebetween. In some embodiments, clip 20 may slide between the unlocked and locked positions along a track 28, in directions A and B respectively. Without intending to be limiting, as seen in
(24) In some embodiments, clip 20 may be a spring loaded clip adapted to exert a downward force on clamp 14 when in the locked position. In other embodiments, the clip 20 may be a rigid, U-shaped clip, sized so as to snugly receive the lower and upper portions 16, 18 of clamp 14.
(25) As best viewed in
(26) The device 10 may further include at least one resilient retaining arm 26, the retaining arm 26 extending cantilevered from the upper portion 18 of the clamp and in opposed facing relation to the slider guide 22. The retaining arm 26 extends along the exterior surface X of the zippered track 6, so as to abut at least the zipper tape 7a and/or 7b. In some cases, the retaining arm 26 may abut portions of the zippered compartment 11 adjacent the zipper tape 7a and/or 7b. The retaining arm 26 exerts a downward pressure on the body of the slider head. When slider head 2 is engaged by releasable lock 21, the downward pressure exerted by the retaining arm 26 assists in maintaining engagement between the device 10 and the slider head 2. In some embodiments, the retaining arm 26 is advantageously resilient so as to be capable of flexing or deflecting in direction B, which enables the retaining arm 26 of device 10 to accommodate different sizes and shapes of slider heads 2.
(27) In use, the zipper locking device 10 may be installed on a zippered compartment by, firstly, anchoring the device 10 to the zippered closure 4, and then engaging the slider 1 of the zippered closure with the releasable lock 21. To install the anchor 12 of the device 10 illustrated in
(28) To lock the zippered closure, the releasable lock 21 releasably engages with slider head 2 of the slider 1 of the zippered closure 4. In use, the slider 1 is moved along the zipper tape 7a and 7b in direction D towards the slider guide 22 of the zipper locking device 10. As the slider 1 approaches the releasable lock 21, the front edge 3 of the slider 1 encounters the smooth ramp portion 24a of latch 24, allowing the slider head 2 to travel over the latch 24. As slider 1 continues to travel in direction D along the resiliently flexible slider guide 22, the head 2 of the slider is fully engaged when the rear edge 5 of the slider 1 passes over latch 24 of slider guide 22. Once the slider head 2 has passed over latch 24, the resilient slider guide 22 urges the latch 24 upwardly behind the slider head 2 so as to form a stop. In some embodiments of the present disclosure, the distal end 22a of the releasable lock 21 may include a wide surface so as to abut the interior surface I of the zipper tape 7 and prevent the slider guide 22 from flicking upwards upon making contact with slider head 2.
(29) Advantageously, the zipper locking device disclosed herein releasably engages a portion of the body of the slider head 2, which enables use of the zipper locking device with a range of different zippered closures 4, as the design of the slider head 2 is relatively standardized across different zippered closures 4. The standardization of the design of a slider head 2 is in contrast to the non-standardization of the design of a pull tab (not shown), which is typically coupled to the slider head 2 by a pull tab coupling 2a. The applicant observes that pull tabs, which serve the function of enabling a user to pull the slider head 2 along the zipper track 6, may be made of a range of materials including but not limited to metal, cords, plastic and/or leather, may adopt a wide variety of shapes and designs, and the design of pull tabs is often informed by aesthetic considerations.
(30) In contrast to the variation in the design of pull tabs, the body of a standard slider head 2, as known in the art, comprises an upper plate 2b coupled to a lower plate 2c by a vertical member (not shown). The lower plate 2c has a rearward edge 5 and a front edge 3. A pull tab coupling 2a is typically mounted to the upper plate 2b of the slider head 2, for coupling a pull tab to the slider head 2. The applicant notes that while the examples of embodiments of a zipper locking device disclosed herein feature locks and/or latches that releasably engage, for example, a rearward edge 5 of the lower plate 2c of the slider head 2, the present application is not intended to be limited to such embodiments. For example, the zipper locking devices disclosed herein may be configured to engage any portion of the body of a standard slider head 2, such as any portion of the upper and lower plates 2b, 2c, the pull tab coupling 2a and/or the vertical member, and any such embodiments are intended to be included in the scope of the present disclosure.
(31) Referring to the embodiment illustrated in
(32) Advantageously, this slider release operation requires some level of dexterity, for example by typically requiring depression of the resiliently flexible slider guide 22 with one hand while using the other hand to slide the slider 1 in direction E. While such an operation may be easily performed by a person with sufficient dexterity and coordination, such as a typical adult, most small children would not have sufficient strength in their hands or the coordination and dexterity required to perform this operation. As such, this device may prevent a small child from accessing the zippered compartment, while not hindering an adult from doing so. As well, the device 10 may sufficiently deter a thief from accessing a zippered compartment secured with the zipper locking device of the present disclosure, for example when the user of the zipper locking device is travelling in a crowded public space, due to the dexterity required to perform the unlocking operation and release the zipper slider from the lock.
(33) It will further be appreciated that different configurations of the zipper locking device may be used so as to effectively lock zippered compartments having different configurations of zippered closures. For example, it may be the case that a zippered compartment includes a zippered closure having two sliders which are brought so as to be adjacent to one another when the zippered closure is in a closed position. For such a zipper configuration, the zipper locking device disclosed herein may be modified so as to include an anchor, such as anchor 12, in the middle of the device flanked by releasable locks 21 on each side of the anchor. In such a configuration, use of the device may include anchoring the device to a portion of the zippered closure which is somewhere in-between the two ends of the zippered closure 4, and then engaging each of the two zipper sliders 1 with each of the two respective releasable locks 21 on the device. Other possible variations of the zipper locking device are intended to be included in the scope of the present disclosure.
(34) A further embodiment of the zipper locking device 100 is illustrated in
(35) The clamp 114 may optionally include a clip track 128 for receiving the clip 120. The clip track 128 may assist with retaining the clip 120 in place when installed on the clamp 114 of the anchor 112, as the ridges 128c defining the track 128 may prevent the clip 120 from sliding out of place in direction Y, such as shown in
(36) Zipper locking device 100 may also include a resilient retaining arm 126, which serves a similar function to the resilient retaining arm 26 in device 10 in that the resilient retaining arm 126 receives and engages a portion of the slider head 2 when slider head 2 is engaged with the device 100.
(37) As with the device 10, the zipper locking device 100 includes a lock 121 extending cantilevered from the lower portion 116 of clamp 114. The lock 121 includes a resiliently flexible slider guide 122, the slider guide 122 having a distal end 122a distal from the anchor 112. The slider guide 122 also includes a latch feature 124 for engaging the body of the slider head 2. The latch 124 includes a hook 124a, the hook 124a angled towards the anchor 112 of the device. Unlike the device 10 illustrated in
(38) As best viewed in
(39) It will be appreciated by a person skilled in the art that other variations of the anchor and releasable locking mechanisms of the device disclosed herein, which have the respective functions of anchoring the device to the zippered closure 4 of the zippered compartment and releasably engaging the body of a standard slider head 2 of a standard zippered closure 4, are intended to be included within the scope of the present disclosure and that the invention disclosed herein is not intended to be limited to the specific embodiments disclosed.
