Expandable rack assembly with telescoping tube sections adapted to facilitate connection to side supports

1. A rack assembly comprising:

a. a plurality of side supports each having edge surfaces, interior front surfaces, unblemished exterior rear surfaces having no holes therein and a longitudinal hole extending partially into said interior front surfaces, said interior front surfaces being oriented in a plane substantially parallel relative to said exterior rear surfaces and also substantially perpendicular to the edge surfaces; and

b. a plurality of substantially horizontally oriented telescoping tubes extending between the interior front surfaces of said side supports, said telescoping tubes including:

(i.) a first telescoping tube portion, said first telescoping tube portion having a front end of a first diameter and a rear end which flares radially outward to an intermediate diameter, said intermediate diameter being larger than said first diameter of said front end; and

(ii.) a second telescoping tube portion sized to receive said first telescoping tube portion, said second telescoping tube portion having a rear end of a second diameter and a front end which tapers radially inward to said intermediate diameter to prevent said first telescoping tube section from longitudinally passing out of said second telescoping tube portion;

c. means for releasably attaching said first and second telescoping tube portions at distal ends of said front end of said first telescoping tube portion and said rear end of said second telescoping tube portion to said side supports at only said interior front surfaces, said attaching means also facilitating the adjustment of said telescoping tubes relative to said side supports through a rotation of said first telescoping tube portion and a simultaneous counter-rotation of said second tube portion relative to said rotation of said first telescoping tube portion, said attaching means including:

(i.) a first plug member sized for receipt by said front end of said first telescoping tube portion, said first plug member having at a front end thereof an externally threaded rod sized for receipt by said longitudinal hole of said interior front surfaces of said side supports, and at a rear end thereof a first insert member sized for receipt in an opening of said front end of said first telescoping tube portion to facilitate the retention of said first plug member and said externally threaded rod on said front end of said first telescoping tube portion; and

(ii.) a second plug member sized for receipt by said rear end of said second telescoping tube portion, said second plug member having at a rear end thereof an externally threaded rod sized for receipt by said longitudinal hole of said interior front surfaces of said side supports, and at a front end thereof a second insert member sized for receipt in an opening of said rear end of said second telescoping tube portion to facilitate the retention of said second plug member and said externally threaded rod on said rear end of said second telescoping tube portion.

2. The rack assembly of claim 1 , wherein each one of said side supports has a base portion including a pair of outwardly extending axles.

3. The rack assembly of claim 2 , wherein each one of said axles is provided with a transport mechanism for facilitating the transport of said rack assembly on an underlying surface area.

4. The rack assembly of claim 3 , wherein said transport mechanism comprises a wheel.

5. The rack assembly of claim 1 , further comprising a longitudinal cross member for connecting each of said plurality of side supports.

6. The rack assembly of claim 1 , wherein said telescoping tubes are adapted for attachment to said side supports in a staggered arrangement.
