Abstract

An adjustable shelving assembly includes at least two support rails, at least one geared rack provided in each of the at least two support rails, and an actuating mechanism placed adjacent to the at least one geared rack. The actuating mechanism is configured to support at least one shelf and facilitates movement of the at least one shelf along the at least two support rails. The actuating mechanism includes a pinion mating with the at least one geared rack, a plurality of permanent magnets mounted coaxially inside the pinion, ferromagnetic disks provided on either ends of the pinion, and a shaft placed axially in the pinion, connecting the permanent magnets. The permanent magnets magnetize or demagnetize the ferromagnetic disks when the shaft is rotated for locking or unlocking the at least one shelf.

First claim

What is claimed is:

1. A method for adjusting shelf height, the method comprising:
providing an actuating mechanism configured to support at least one shelf, the actuating mechanism comprising a plurality of permanent magnets mounted coaxially inside a pinion that has ferromagnetic disks provided on either end and a shaft placed axially in the pinion, the pinion mates with at least one geared rack in each of at least two support rails;
demagnetizing the ferromagnetic disks to unlock and facilitate movement of the shelf along the support rails by rotating the shaft in one direction; and
magnetizing the ferromagnetic disks to lock the shelf and arrest movement by rotating the shaft along the support rails in another direction.

2. The method of claim 1 wherein the shelf further comprises a frame, a link assembly and a handle mounted at a fore end of the frame, a plurality of links connected to the handle and the method further comprises actuating the handle of the link assembly to rotate the shaft.

3. The method of claim 1 , wherein the ferromagnetic disks provided on either end of the pinion are in contact with the support rails.

4. The method of claim 1 , wherein the support rails are spaced apart from each other in a least a substantially vertical orientation.

5. The method of claim 1 , wherein the shelf is placed at least substantially horizontal to the support rails.
