Abstract

A storage rack a base frame rod structure formed by bending one single metal wire rod into a predetermined shape and a top frame rod structure formed by bending one single metal wire rod into a predetermined shape and welded to the base frame rod structure such that multiple storage racks can be received together by inserting one storage rack of another storage rack to save storage space, or multiple storage racks can be stacked together, constituting a multi-deck combination storage rack.

Claims

1. A storage rack comprising a base frame rod structure, said base frame rod structure comprising two symmetrical pairs of foot rod portions, two horizontal top rod portions transversely arranged in parallel at two first opposite sides and respectively connected between top ends of said foot rod portions, and two stretcher rod portions longitudinally arranged in parallel at two second opposite sides perpendicular to said first opposite sides and respectively connected between bottom ends of said foot rod portions, the two foot rod portions of one same pair being kept in a sloping status such that the distance between the two ends of the two foot rod portions is smaller than the distance between the bottom ends thereof;

and a top frame rod structure, said top frame rod structure comprising two longitudinal rod portions respectively spaced above said stretcher rod portions in a parallel member, two transverse rod portions respectively connected between and formed integral with two opposite ends of said two longitudinal rod portions and respectively welded to the foot rod portions of said base frame rod structure at an elevation below said horizontal top rod portions, said longitudinal rod portions being disposed at an elevation above said transverse rod portions so that a gap is defined between said top frame rod structure and each said foot rod portion in each of four corners of the storage rack.

2. The storage rack as claimed in claim 1, further comprising two supplementary bearing rods fixedly connected between said two horizontal top rod portions and arranged in parallel, each said supplementary bearing rod having a longitudinal series of wave-like portions.

3. The storage rack as claimed in claim 1, as claimed in claim 1, wherein said stretcher rod portions being disposed at an elevation above the bottom ends of said foot rod portions so that each stretcher rod portion has each end thereof terminating in a downwardly curved protruding portion that connects to the bottom end of one said foot rod portion
