ZIPPER PULL TAB LOCK

Abstract

Various embodiments include a zipper pull tab lock for releasably securing a zipper pull tab to prevent movement of a zipper relative to rows of zipper teeth. A protrusion or paw within the zipper pull tab lock engages the hole defined in the zipper pull tab to prevent removal of the zipper pull tab from the zipper pull tab lock. To release the zipper pull tab from the zipper pull tab lock, a user depresses an release tab (or button) disposed adjacent the upper surface of the zipper pull tab lock, which causes the protrusion or paw within the zipper pull tab lock to move downwardly and disengage from the hole of the zipper pull tab, allowing the pull tab to be slidably disengaged from the zipper pull tab lock.

Description

BACKGROUND OF THE INVENTION

A play yard, which is sometimes referred to as a play pen, is a containment device that typically includes a rigid enclosure having four side walls, a floor, and an upper opening through which a child may be moved in and out of the play yard. The rigid enclosure includes upper and lower horizontal frame members that are joined by vertical frame members, and a solid fabric material is positioned over the frame members. The side walls typically include a mesh portion that extends between the solid fabric material covering the frame members to allow for visibility of the child within the play yard and provide adequate air flow to the child. In addition, the frame members may be collapsible with respect to each other to allow for easier portability and storage of the play yard.

Many play yards further include a bassinet that can be hung from the upper horizontal frame members of the play yard. In particular, the bassinets, such as the bassinet for attachment in a child's play yard described in U.S. Pat. No. 5,778,465, typically include four side walls, a floor, and a plurality of U-shaped plastic hooks that extend from the upper perimeter of two or more of the four side walls. The plastic hooks are configured for engaging the upper horizontal frame members of the play yard such that the floor of the bassinet is suspended above the floor of the play yard. In some products, the bassinet includes a fabric loop along the upper perimeter of two or more of the four side walls, and each fabric loop receives a metal rod. The ends of each metal rod extend outside of the fabric loop and are received into molded U-shaped hooks disposed adjacent the upper horizontal frame members. Some other products, such as the bassinet for suspension in a play yard play described in U.S. Pat. No. 6,434,767, include a combination of the U-shaped plastic hooks and the fabric loop and metal rod engagement means to support the bassinet floor above the play yard floor.

In addition, many play yards are collapsed by pulling up on a strap or handle disposed on the floor of the play yard and attached to the horizontal frame members and then, by releasing hinges along the upper horizontal frame members. By pulling up on the strap or handle, the horizontal frame members and the vertical frame members are drawn toward a central vertical axis extending through the floor of the play yard. However, this strap or handle is inaccessible when the bassinet is installed within the play yard, resulting in the additional, often difficult step of having to remove the bassinet to access the strap or handle when the play yard is to be transported or stored.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION

Various embodiments of the invention are described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown in the figures. These inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements.

Brief Summary

Various embodiments of the invention provide an improved play yard and bassinet combination. For example, FIG. 1 illustrates a play yard and bassinet combination 50 according to various embodiments of the invention in which the bassinet assembly 100 is secured adjacent the inner walls of the play yard 200 with a zipper. In particular, the play yard 200 includes four walls 206 and a floor 207, and an inner portion 204 of the walls 206 adjacent the upper perimeter of the walls 206 includes a row of zipper teeth 205 (shown in FIGS. 3-5). The bassinet assembly 100 includes a floor 102 and side walls 108 that extend upwardly from the floor 102. The upper edge of the side walls 108 includes a row of teeth 130 (shown in FIGS. 3-5), and one or more zippers engage the teeth 130 of the bassinet assembly 100 with the corresponding row of teeth 205 on the play yard 200 to attach the bassinet assembly 100 to the inner portion 204 of the side walls 206 of the play yard 200.

To provide an added layer of support should a primary means (e.g., zipper, U-shaped hooks, metal rod/hook arrangement) for securing the bassinet assembly 100 within the play yard 200 fail, the bassinet assembly 100, according to various embodiments, further includes a plurality of male or female buckles 140 spaced around the outer perimeter of the bassinet floor 102, and the buckles 140 mate with corresponding female or male buckles 215 (shown in FIGS. 4-5), respectively, attached to portions of side walls 206 of the play yard 200. If the primary means for securing the bassinet assembly 100 were to fail, the engaged buckles 140, 215 would prevent the bassinet floor 102 from dropping towards the floor 207 of the play yard 200.

In addition, as shown in FIG. 6, according to various embodiments, the bassinet assembly 100 defines an opening 160 in a medial portion of the floor 102 through which a user can access a release mechanism 250 on the floor 207 of the play yard 200 to collapse the play yard 200 without removing the bassinet assembly 100 from the play yard 200. In the embodiment described above in relation to FIG. 1 in which the bassinet assembly 100 is secured to the play yard 200 using a zipper or other flexible fastener, the play yard 200 can be collapsed without removing the bassinet assembly 100 from the upper opening of the play yard 200.

The bassinet assembly 100 is further configured to provide an inclined surface for a baby. According to various embodiments, as shown in FIGS. 1 and 10-12, the floor 102 of the bassinet assembly 100 includes an inclinable flap 104, and the inclinable flap 104 includes a row of zipper teeth 106 along a portion of the perimeter of the inclinable flap 104. Three adjacent side walls 108 of the bassinet assembly 100 include a corresponding row of zipper teeth 109 between an upper and lower perimeter of the side walls 108. In particular, on two opposing side walls 108a, 108b, the row of zipper teeth 109 is disposed along an inclined path relative to the floor 102, and on a side wall 108c intermediate the two opposing side walls 108a, 108b, the row of zipper teeth 109 is disposed along a path parallel to the floor 102. The rows of teeth 106, 109 are engaged with one or more zippers to secure the inclinable flap 104 at an angle with respect to the floor 102. For example, in one embodiment, the angle of incline is about 10°.

In other various embodiments, the bassinet assembly 100 may further include at least one rod 120 that is disposed below at least a portion of an upper surface of the bassinet floor 102 to support a mattress pad 300 to be disposed on the upper surface of the bassinet floor 102. In one embodiment, each rod 120 includes a static portion 121 and an inclined portion 122, and the longitudinal axes 123, 124 of each portion 121, 122, respectively, are disposed at an angle to each other (e.g., about 10°). Each rod 120 is at least partially disposed in one or more pockets 125 that are attached below the upper surfaces of the floor 102 and the inclinable flap 104 of the bassinet assembly 100 such that the static portion 121 is below a first half 102a of the floor 102 and the inclined portion 122 is below the inclinable flap 104. When the inclinable flap 104 is pulled upwardly, each rod 120 rotates from a flat position, which is shown in FIGS. 15 and 16, to an inclined position, which is shown in FIGS. 13 and 14. Similarly, when the inclinable flap 104 of the floor 102 is lowered to the flat position, each rod 120 rotates from the inclined position to the flat position.

According to various embodiments, the bassinet assembly 100 and the play yard 200 may utilize zipper pull tab locks for releasably securing zipper pull tabs to prevent the zippers from movement relative to rows of zipper teeth. Exemplary zipper pull tab locks that may be utilized are described in relation to FIGS. 17-27.

Various features of a bassinet assembly and a play yard and bassinet assembly combination according to various embodiments are described below.
