Abstract

A collapsible and extendable storage rack is provided. The rack includes a first end support, a second end support, a top shelf hingedly attached to the first end support and selectively connectable to the second end support, a bottom shelf hingedly attached to the second end support and selectively connectable to the first end support, and a middle shelf. The middle shelf includes a first portion and a second portion hingedly connected to the first portion. The first portion is hingedly connected to the first end support. The second portion is hingedly connected to the second end support. The rack is movable between a collapsed position and an extended position.

First claim

What is claimed is:

1. A collapsible and extendable storage rack comprising:
a first end support;
a second end support;
a top shelf hingedly attached to the first end support and selectively connectable to the second end support;
a bottom shelf hingedly attached to the second end support and selectively connectable to the first end support; and
a middle shelf comprising a first portion and a second portion hingedly connected to the first portion, the first portion being hingedly connected to the first end support, the second portion being hingedly connected to the second end support;
whereby the rack is movable between a collapsed position in which the middle shelf is folded between the first and second end supports, the top shelf extends along an outside of the first end support generally parallel thereto, and the bottom shelf extends along an outside of the second end support generally parallel thereto, and an extended position in which the first and second end supports are spaced from one another, and the top, middle and bottom shelves extend generally perpendicular to the first and second end supports between the first and second end supports.

2. The rack according to claim 1 , further comprising a first secondary support and a second secondary support, wherein the first secondary support is connected to the first end support and the first portion of the middle shelf, and wherein the second secondary support is connected to the second end support and the second portion of the middle shelf.

3. The rack according to claim 2 , wherein the first secondary support and the second secondary support are each configured as scissor arms having first and second arm portions which are hingedly connected to one another.

4. The rack according to claim 3 , wherein the top shelf, the bottom shelf, and the middle shelf each comprise a wire mesh panel.

5. The rack according to claim 3 , wherein the top shelf, the bottom shelf, and the middle shelf each comprise closed panels.

6. The rack according to claim 1 , further comprising a first bracket and a second bracket each associated with a corresponding one of the first end support and the second end support, wherein, when the rack is in the extended position, the first bracket limits downward movement of the top shelf toward the middle shelf, and the second bracket engages the bottom shelf.

7. The rack according to claim 6 , wherein, when the rack moves from the collapsed position toward the extended position, the second end support is tilted outwards and then back inwards, with respect to the first end support, in order to allow the bottom shelf to engage the second bracket.

8. The rack according to claim 7 , wherein, when the rack moves from the collapsed position toward the extended position, the top shelf rotates in a clockwise direction with respect to the first end support, and the bottom shelf rotates in a clockwise direction with respect to the second end support.

9. The rack according to claim 8 , wherein the first end support and the second end support each comprise a first end and a second end disposed opposite the first end, wherein, when the rack is in the collapsed position:
the first end of the first end support is disposed proximate the first end of the second end support,
the second end of the first end support is disposed proximate the second end of the second end support,
the top shelf extends from the first end of the first end support toward the second end of the first end support, and
the bottom shelf extends from the second end of the second end support toward the first end of the second end support.

10. The rack according to claim 1 , further comprising a first cap and a second cap, wherein the first end support and the second end support each comprise first and second uprights, and wherein the first cap and the second cap each comprise an elongate member with a first opening and a second opening for accepting the first and second uprights of the first and second end supports.

11. The rack according to claim 10 , wherein the first cap and the second cap are each detachably connected to a corresponding one of the first and second end supports in order to allow the top shelf to move from the collapsed position to the extended position.
