Abstract:
An adjustable length shelf system adapted to be mounted between two vertical supports, the system comprising:(a) a main shelf section (22) having a predetermined length and cross-sectional shape, the main shelf section having a lower portion attached around a bottom side of a first hollow tube (10) and a top portion thereof extending above the tube thereby forming a shelf surface (20), whereby the first hollow tube has a first end adapted to be biased against one of the vertical supports and a second end, and (b) a telescopic shelf section (16) comprising a first piece (26) and an inner shelf piece (28) whereby the telescopic shelf section has a predetermined cross-sectional shape substantially identical to the main shelf section (22) whereby a lower portion of the first piece (26) is slidable around the first hollow tube (10) and a second hollow tube (12), and a top portion of the first piece forms a shelf surface and extends above and slidably overlays the second tube, the inner shelf piece (28) defining a shelf surface slidably overlaying the first and second hollow tubes (10 and 12) and the shelf surface (20) of the main shelf section (22), whereby a first end of the second hollow tube is inserted into the second end of the first hollow tube and a second end of the second hollow tube is adapted to be biased against the other one of the vertical supports; wherein the system can be assembled to span the distance between the vertical supports by biasing the first end of the first hollow tube and the second end of the second hollow tube against respective vertical supports and slidably moving the first piece (26) of the telescopic shelf section (16) over the second hollow tube (12) towards the main shelf section (22) and lifting and sliding the inner shelf piece (28) over the second tube towards the second end of the second tube so that the top portions of the main shelf section and telescopic shelf section form a substantially horizontal shelf that substantially spans the distance between the vertical supports.
