Description

BACKGROUND

1. Field of the Invention

The present invention generally concerns a rack shelf system. More particularly, the present invention relates to a rack shelf with collapsible side walls.

2. Description of the Related Art

Traditionally, rack shelves are rectangular and have a flat, thin sheet of a durable material as a base. On both sides of the base along the width of the shelf, a side wall is attached to the base. The side wall may be integrated into the base such that the entire rack shelf is continuous material. Alternatively, the side walls may be welded to the base. Each side wall generally has a number of holes or slots. The rack into which the shelf is placed has protrusions on the inside of its walls. Thus, when the shelf is inserted into the rack, the shelf will engage with the inside walls of the rack when the rack protrusions interlock with the holes or slots on the shelf side walls. This simple design is sturdy because the side walls are firmly connected to the base of the shelf. Therefore, it can bear weight when placed inside the rack. However, this type of shelf can be costly and inefficient to ship, because the bulk of the base and the side shelves require a large box.

An improved design uses only one wall plate that consists of two vertical rails affixed to two horizontal rails to form a rectangular frame. The frame is hinged at the mid-point of each of the two horizontal rails, which allows the frame to fold lengthwise. This fold-over frame design utilizes a solid rectangular frame, with four rails as opposed to three rails, and therefore offers more stability for mounting appliances to walls.

Designs that are pre-assembled (e.g., a fold-over design) are less complicated for users because they do not require assembly and they offer more stability. However, the pre-assembled design is more difficult and expensive to ship due to its size, which is typically larger than the traditional disassembled mounting frame design.

There is a need for a mounting frame apparatus and mounting system that is stable, user-friendly, and compact.

SUMMARY OF THE CLAIMED INVENTION

A flexible rack shelf is also disclosed. The rack shelf has two sides and a base. Both the sides and the base have a number of perforations or holes in them through which a screw or other hanger can fit. The base and the sides are connected by a hinge (or hinges). The hinged sides allow the sides to lay flat against the base when the rack is not in use, which makes shipping the rack shelf more efficient and less expensive.

A flexible rack shelving system is also disclosed. The system utilizes a rack shelf that has two sides and a base. Both the sides and the base have a number of perforations or holes in them through which a screw or other hanger can fit. The base and the sides are connected by a hinge (or hinges). The rack shelving system also includes a rack. The rack shelf is placed inside the rack. To attach the rack shelf to the rack, screws or other hangers on the insides of the rack are placed through the holes of the rack shelf.

BRIEF DESCRIPTION OF THE FIGURES

FIG. 1A illustrates an exemplary flexible rack shelf.

FIG. 1B illustrates an exemplary side wall of a flexible rack shelf.

DETAILED DESCRIPTION

Embodiments of the present invention provide a flexible rack shelf that may be mounted to a rack. Persons of ordinary skill in the art will realize that the following description of the presently invention is illustrative only and not in any way limiting. Other embodiments of the invention will readily suggest themselves to such skilled persons.

Referring now to FIG. 1A, illustrating an exemplary embodiment of a flexible rack shelf, a shelf base 105 is coupled to vertical side shelves, one of which is labeled 110. Each side shelf 110 has a plurality of apertures, one of which is labeled 115. The vertical side shelves are collapsible in a fold-over fashion, such that the insides of vertical side shelves 110 lay flat against the top of shelf base 105. Each of the vertical side walls 110 is pivotally mounted along the width of shelf base 105. Each vertical side shelf is hinged at its midpoint by a connector, one of which is labeled 120. The connector 120 may include any type of hinge, including by way of example and not limitation, a laptop hinge, a butterfly hinge, a barrel hinge, or a flush hinge.

When the flexible rack shelf is fully assembled, it attaches to a rack (not shown) by outwardly extending L-shaped wings, one of which is labeled 125, that run along the length of each vertical side wall 110. Each wing has at least one aperture, one of which is labeled 130, that may be used to connect to a protruding object on a rack. Additionally, each L-shaped wing 125 has an aperture 135 on the end of the horizontal portion of the L-shape. The aperture 135 may line up with an aperture of the base 105 and be secured to the base 105 by using, for example, a nail or a screw.

In one embodiment of the present invention, a support mechanism comprises a horizontal bar 140 that has two downward-facing arms, one of which is labeled 145. Each arm 145 has a knob, one of which is labeled 150, that may be placed through one of the apertures 115 in vertical side wall 110. Once a knob 150 is placed through an aperture 115 of each of the side walls 110, the side walls 110 are reinforced, making the entire assembly more rigid and, thus, less likely to collapse when objects are placed on the shelf.

Referring now to FIG. 1B, illustrating an exemplary side wall of a flexible rack shelf, vertical side wall 110 of FIG. 1A may additionally contain one or more cut-out tabs, one of which is labeled 155. A user may push the cut-out tab 155 inward from side wall 110 horizontally until the broad side of the tab interfaces with base 105. Thus, the cut-out tab 155 can be used as an additional hinge between side wall 110 and base 105.

The above description is illustrative and not restrictive. Many variations of the invention will become apparent to those of skill in the art upon review of this disclosure. While the present invention has been described in connection with a variety of embodiments, these descriptions are not intended to limit the scope of the invention to the particular forms set forth herein. To the contrary, the present descriptions are intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claim and otherwise appreciated by one of ordinary skill in the art.
