Abstract

A rack assembly has two support frames, each support frame having at least one connecting member comprising a short tube welded on the support frame and an insertion tube inserted in the short tube. At least one shelf is positioned between the two support frames, each end of each shelf having at least one hook that is received in a corresponding short tube to detachably connect the shelf with the support frame. The shelves can be conveniently attached and detached from the support frames.

First claim

What is claimed is:

1. A rack assembly, comprising:
two support frames, each support frame having at least one connecting member comprising a first tube secured to the support frame, the first tube having an inner space with an opening that opens upwardly, and a separate insertion tube having an internal space with an opening that opens upwardly, wherein the insertion tube is inserted through the opening of the first tube and fits completely inside the inner space of the first tube; and
at least one shelf positioned between the two support frames, each end of each shelf having at least one hook that is inserted through the opening of a corresponding insertion tube and received in the corresponding insertion tube to detachably connect the shelf with the support frame.

2. The assembly of claim 1 , wherein each support frame comprises two identical vertical tubes and at least one horizontal tube for connecting the two vertical tubes, wherein each vertical tube has a medial surface, and the at least one connecting member is disposed on the medial surface of each vertical tube, with the connecting members disposed on the two vertical tubes positioned at the same vertical heights.

3. The assembly of claim 2 , wherein each vertical tube, has a medial surface, and the first tube is secured to the medial surface of each vertical tube of the support frames, and the first tube has a four-sided cross-section.

4. The assembly of claim 2 , wherein an insertion hole is provided at the upper end of each vertical tube, and a threaded hole is provided at the lower end each vertical tube, and wherein a connector is coupled to the upper end of each vertical tube.

5. The assembly of claim 4 , wherein the connector comprises a screw rod and a connection peg.

6. The assembly of claim 1 , wherein the insertion tube is snuggly fitted inside the first tube.

7. The assembly of claim 1 , wherein a portion of the hook rests on an edge of the insertion tube at the opening of the insertion tube.

8. A rack assembly, comprising:
two support frames, each support frame comprising two identical vertical tubes and at least one horizontal tube for connecting the two vertical tubes, each vertical tube having two connecting members provided thereon, and with each of the connecting members on each vertical tube aligned at the same vertical height as a corresponding connecting member on the other vertical tube, each connecting member including a first tube that is secured to the vertical tube in a manner such that the first tubes of a vertical tube are facing the first tubes of the other vertical tube of the same support frame, each first tube having an inner space with an opening that opens upwardly, each connecting member also including a separate insertion tube having an internal space with an opening that opens upwardly, wherein the insertion tube is inserted through the opening of a corresponding first tube and into the inner space of that first tube; and
at least one shelf positioned between the two support frames, each shelf having an end wall, each end wall of each shelf having two hooks, with each hook secured to the corresponding end wall of the shelf at a location slightly offset from the corresponding corner of the shelf, and each hook is inserted through the opening of a corresponding insertion tube and received in the corresponding insertion tube to detachably connect the shelf with the support frame.

9. The assembly of claim 8 , wherein the end wall of the shelf at a corner of the shelf exerts a first engagement force on a first wall of the vertical tube, and a side of the hook exerts a second engagement force on an adjacent second wall of the vertical tube that is perpendicular to the first wall, with the first and second engagement forces being transverse to each other.

10. The assembly of claim 9 , wherein each insertion tube is configured with two opposing straight segments that are adapted to contact the opposite sides of one of the hooks.

11. The assembly of claim 8 , wherein each insertion tube is configured with two opposing straight segments that are adapted to contact the opposite sides of one of the hooks.

12. The assembly of claim 8 , wherein the insertion tube is snuggly fitted inside the first tube.

13. The assembly of claim 8 , wherein a portion of the hook rests on an edge of the insertion tube at the opening of the insertion tube.
