Abstract

A kit for converting a standard sit-down desk to a stand-up desk. The kit includes a frame having a plurality of leg extensions secured with end rails and a plurality of side supports of selected length. Selected of the leg extensions are pivotally carried between retracted and extended positions. The kit also includes a foot rail, a shelf, a plurality of spacers and a plurality of collars. For shipping, the pivotable leg extensions, shelf and foot rail are placed parallel with the end rail. In use, the pivotable leg extensions are moved into an extended position and secured by the foot rail and shelf. The desk legs are interconnected with the leg extensions by the collars.

Claims

1. A conversion kit for adjusting the length of the legs of a desk comprising:

a support frame including a forward pair, a rear pair, and an intermediate pair of leg extensions of selected length fixedly interconnected with side supports, said leg extensions being arranged to be aligned with said legs of said desk;

a plurality of collars adapted to fit over ends of said leg extensions and said legs of said desk for uniting said leg extensions of said support frame with said legs of said desk, said intermediate pair of leg extensions comprising two elongated members pivotally interconnected with a hinge;

a plurality of spacers of selected size which are adapted to be positioned inside said collars between opposed ends of said legs and leg extensions;

whereby,

the height of said desk is adjusted vertically from a standard height to a variable stand-up height as determined by the length of said leg extensions and said spacers.

2. The kit of claim 1 wherein said kit includes a foot rail adapted to be secured over opposed of said side supports and adjacent said forward pair of said leg extensions.

3. The kit of claim 1 wherein said kit includes a shelf positionable adjacent said intermediate and rear pairs of leg extensions of said support frame.

4. The kit of claim 1 wherein said collars are formed of one of metal, wood, plastic and paper and are colored to match said legs of said desk.

5. A conversion kit for converting a sit-down desk having a plurality of legs into a stand-up desk, said kit comprising:

a frame having a pair of forward, intermediate and rear leg extensions, said frame being convertible between a first retracted position and a second extended position, said intermediate pair of leg extensions comprising two elongated members interconnected with a pivot;

a plurality of collars, said collars being stored within said kit when said frame is in said first retracted position and being engaged with upper ends of said leg extensions when said frame is in said second extended position;

a foot rail contained within said kit when in said first retracted position and connected with said side supports stabilizing said frame with said kit in said second extended position;

wherein,

said frame is folded into said first contained position for storage/shipping in said retracted position and is opened into said second extended position in which it is operative to engage with and elevate said desk.

6. The kit of claim 5 wherein the pivots of said intermediate leg extensions allow said frame to pivot between said first retracted and second extended positions.

7. The kit of claim 6 further including a shelf, said shelf being engaged between said rear and intermediate of said leg extensions when said frame is in said extended second position.
