WRISTBAND CLASP ASSEMBLY

Abstract

A wristband assembly is provided having a strap assembly with a first strap and a second strap. Each strap has a plurality of apertures arranged thereon such that the apertures on each strap align, allowing for prongs of a clasp member to pass through and connect each strap. The clasp member has an upper lateral bar disposed at an offset position above a lower lateral bar, whereby the upper lateral bar acts as a snag-guard. Each prong has a first lip and a second lip, both of which are slightly larger than the corresponding apertures through which the prongs pass through, allowing each lip to hold a strap in place when engaged with the clasp member. When the two straps are connected via the clasp member, the clasp member acts as a snag-guard to the first strap and simultaneously as the sole means of connection between the two straps forming a wristband.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Referring now to the drawings, and particularly FIGS. 1A-B, there is shown a wristband assembly 10 having a first strap 12 and a second strap 14, connected by a clasp member 20. The first strap 12 and the second strap 14 have a plurality of apertures 16 that align with each strap 12, 14, allowing the wearer to adjust the size of the wristband assembly 10.

[0030] With reference to FIGS. 1A-B and FIGS. 2A-2F, the clasp member 20 has an upper lateral bar 22 that is disposed above the straps 12, 14 and a lower lateral bar 24 that is disposed below the straps 12, 14, when worn. The upper lateral bar 22 and the lower lateral bar 24 are substantially flat, in order to be flush with the straps 12, 14 when engaged. The upper lateral bar 22 and the lower lateral bar 24 are connected by two sidewalls 23. The upper lateral bar 22 is positioned such that when the last set of apertures 40 of the second strap 14 are engaged with the prongs 26. As such, the strap 14 is disengaged from the clasp member 20 by lifting the first strap 12 from an intermediate portion of the strap 14.

[0031] A plurality of prongs 26 extend out from the lower lateral bar 24, designed to pass through corresponding apertures 16 defined on both the first 12 and second 14 straps. The prongs 26 are disposed proximate to the front edge of the lower lateral bar 24, such that the remaining portion of the lower lateral bar 24 can sufficiently support the straps 12, 14 when engaged. The upper lateral bar 22 is offset from the lower lateral bar 24 in order to inhibit the first strap 12 from disengaging from the prongs 26 if the end of the first strap 12 is snagged on an object.

[0032] In an exemplary embodiment, the prongs 26 and corresponding apertures 16 on the straps 12, 14, are triangular. As best seen in FIGS. 2E-F, each prong 26 extends from the lower lateral bar 24, having an intermediate lip 28 at an intermediate portion, and an upper lip 30 spaced distally therefrom. In the exemplary embodiment, the upper lip is disposed atop the prong. The intermediate lip 28 and the upper lip 30 are sized sufficiently larger than the shaft 29 of the prong 26, and the corresponding size of the apertures 16 to require a small amount of force when pressing the prongs 26 through each aperture 16. The straps 12, 14 are made of an elastic material so that each aperture 16 can expand when the lip 28, 30 of the prongs 26 pass through the apertures 16. The upper lip 30 is disposed below the upper lateral bar 22, allowing sufficient space to sandwich the second strap 14 between the intermediate lip 28 and the lower lateral bar 24. The distance between the intermediate lip 28 and the upper lip 30 is sufficient to sandwich the first strap 12 therebetween.

[0033] As shown in FIGS. 1A-B, when the clasp member 20 is engaged with the second strap 14, the prongs 26 push all the way through the desired set of apertures 16 on the second strap 14, such that the second strap 14 is secured by being sandwiched between lower lateral bar 24 and the intermediate lip 28 of the prongs. Once the clasp member 20 is secured to the second strap 14 at the desired location, the first strap 12 is then connected. The first strap 12 is pulled around the user's wrist, and then pushed down on the clasp member 20 such that the prongs 16, extending up through the second strap 14, engage with the desired set of apertures 16 on the first strap 12. As discussed below, the overlap of the first strap 12 with the clasp member 20 can be changed.

[0034] The arrangement and shape of the prongs 26 and corresponding apertures 16 of the straps 12, 14 can vary. In the depicted embodiment, the prongs 26 are triangular, and arranged in straight line. Alternative embodiments could have more, or less, prongs or different shapes, e.g. circular, rectangular, etc. as exemplified in FIG. 4. Additionally, the prongs 26 could be arranged in an offset alignment, or be arranged in multiple columns and/or rows. The arrangement and shape of the prongs 26 should substantially match those of the apertures 16 along each strap 12, 14. In variations, the shape of each prong and corresponding aperture could be arranged with different geometric shapes and alignments. For example, each row of apertures could have a circular prong and a rectangular prong, where the corresponding row of apertures has a circular aperture and a rectangular aperture. Any variation in shape, size, or arrangement of the prongs and apertures can be used, so long as the apertures of both straps align with each other and correspond with the arrangement of the prongs.

[0035] In an alternative embodiment, the prongs 26 could be arranged in a rectangular orientation, where the first row is only tall enough to engage the second strap 14 and the second row is tall enough to engage both straps 12, 14. In this configuration, the clasp member 20 is engaged with the second strap 14 through both rows of prongs 26, where the first strap 12 is only engaged by the second, taller row.

[0036] Referring now to FIGS. 3A-B, the second strap 14 of the wristband assembly 10 is depicted. As shown, the clasp member 20 is engaged with the second strap 14. The prongs 26 of the clasp member 20 are pushed through the desired set of apertures 16 on the second strap 14. The length of the prongs 26 is sufficient to extend above the second strap 14 to securely engage the apertures 16 of the first strap 12 when engaged therewith, as shown in FIG. 1.

[0037] Referring back to FIGS. 1A-B, positioning of the clasp member 20 on the second strap 14, the size of the strap assembly can be adjusted by engaging the prongs 26 with the apertures 16 of the second strap 14 at the desired position. The upper lateral bar 22 of the clasp member 20 is arranged such that it prevents the edge of the first strap 12 from being snagged and disconnecting from the clasp member 20. When the first strap 12 is engaged with the clasp member 20, the end of the first strap 12 is guarded by the upper lateral bar 22 of the clasp member 20. Alternatively, the first strap 12 can also be engaged with the prongs 26 of the clasp member 20 at an intermediate location, with the end of the first strap 12 guided below the upper lateral bar 22. In either configuration, the upper lateral bar 22 acts as a snag guard to prevent the first strap 12 from inadvertent disengagement from the clasp member 20. When the end of the first strap 12 is engaged with the prongs 26 of the clasp member 20, the upper lateral bar 22 guards the first strap 12 from being lifted from the end. When the apertures 16 in the intermediate portion of the first strap 12 are engaged with the clasp member 20, the end of the first strap 12 is threaded between the upper 22 and lower lateral bars 24. In this configuration, if the end of the first strap 12 gets snagged on something that lifts the end of the first strap 12 upward, the upper lateral bar 22 will absorb the force and keep the intermediate portion of the first strap 12 engaged with the prongs 26 of the clasp member 20.

[0038] The clasp member 20 is not permanently connected to either strap 12, 14 of the wristband assembly 10. The clasp member 20 can engage any of set of apertures 26 on either strap 12, 14. This allows the clasp member 20 to be positioned such that the upper lateral bar 22 acts as an anti-snag barrier covering the end of the first strap 12. It also allows the user to attach the clasp member 20 to the second strap 14 at the location that best fits the user's wrist when the first strap 12 is connected. Even when the first strap 12 extends through the clasp member 20, the upper lateral bar 22 prevents the first strap 12 from disengaging the clasp member 20. If the tip edge of the first strap 12 catches on something and bends backward, the upper lateral bar 22 prevents the strap 12 from detaching from the prongs 26.

[0039] Additionally, since the clasp member 20 is not permanently connected to either strap 12, 14, it allows the wristband assembly 10 to be easily modified to cater to left-handed users.

[0040] In use, the user of the wristband assembly 10 wraps the straps 12, 14 around his or her wrist to determine which aperture set 26 and alignment fits the user's wrist. Then the user slides the second strap 14 through the clasp member 20, that is, between the upper 22 and lower lateral bars 24 to the desired set of apertures 16 and presses the strap 14 down, snap-fitting the prongs 26 through said apertures 16. The prongs 26 are pressed through the second strap 14, passing over the second lip 30, and over the intermediate lip 28 until the intermediate lip 28 of the prongs 26 has secured the second strap 14. The remaining length of the prongs 26 and the upper lip 30, stick out above the second strap 14. After connecting the clasp member 20 to the second strap 14, the user connects the first strap 12 to the clasp member 20. The user will arrange the fit of the wristband assembly 10 such that the last set of apertures 40 on the first strap 12 engages the remaining length of the prongs 26. After pressing the first strap 12 down over the prongs 26, the wristband assembly 10 is secure. As shown in FIGS. 1A & 1B, the back edge of the upper lateral bar 22 is positioned ahead of the end of the first strap 12. This prevents the tip of the first strap 12 from inadvertent snagging and disengagement from the clasp member 20.

[0041] In an alternative embodiment, as depicted in FIG. 5, the prongs 26 are located on the upper lateral bar 22, extending downward therefrom. In this embodiment, the clasp member 20 is connected to the first strap 12 (outer strap) at the end portion, and then the second strap 14 (inner strap) is threaded through the clasp member 20 to the desired position and then engaged with the prongs 26 in the corresponding apertures 16.

[0042] In yet another alternative embodiment, depicted in FIG. 6, both lateral bars 22, 24 have prongs 26 extending therefrom. The upper lateral bar 22 has prongs 52 facing downward, and the lower lateral bar 24 has prongs 54 facing upwards. The prongs 26 on each bar 22, 24 are sized to engage with only one strap. The upper prongs 52 on the upper lateral bar 22 engage with the first strap 12 and the lower prongs 54 on the lower lateral bar 24 engage with the second strap 14.

[0043] It should be appreciated from the foregoing that the present invention provides a wristband assembly having a clasp member that acts as the connector of the two straps, and simultaneously acts as a snag-guard.

[0044] The present invention has been described above in terms of presently preferred embodiments so that an understanding of the present invention can be conveyed. However, there are other embodiments not specifically described herein for which the present invention is applicable. Therefore, the present invention should not to be seen as limited to the forms shown, which is to be considered illustrative rather than restrictive.
