## Abstract

An improved construction pillar insertion combination rack made of metal wire material in a rectangular or polygonal form and in a single layer or multiple layers includes multiple side frames, multiple pillars, multiple clamping members, and a top; each limitation corner of the rack comprised of two rings concentrically arranged with the diameter of the upper ring smaller than that of the lower ring; each side frame including an upper and a lower support rods; a connection rod usually made in a waveform being disposed at where between and soldered to both of the upper and the lower support rods; each pillar containing multiple sections with a circumferential slot being defined by any two abutted sections; the pillar being secured with the clamping member at where it to be inserted into the limitation corner; and the top usually related to a mesh being placed on the frame of the rack; alternatively, an upper frame with multiple upper rings of the limitation corner and a lower frame with multiple lower rings of the limitation corner may be separately made in continuous form to be spot soldered at where both ends meet.

## Claims

### Claim 1

A pillar insertion combination rack made in a rectangular or polygonal and a single layer or multiple layers includes multiple limitation corners, a top usually made in a mesh form, multiple side frames, multiple pillars, and multiple sets of clamping members; each limitation corner being comprised of an upper ring and a lower ring made of a metal wire material concentrically arranged with the diameter of the upper ring smaller than that of the lower ring; each side frame made of the same metal wire material being comprised of an upper support rod and a lower support rod, each shorter side frame and each longer side frame being disposed at a right angle to each other in case of a rectangular rack; a connection rod usually made in a waveform being disposed at where between and soldered to both of the upper and the lower support rods; each pillar containing multiple sections with a circumferential slot defined between any two abutted section; the clamping member comprised of two identical halves facing each other secure the pillar at where the pillar to be inserted into the limitation corner by biting two circumferential slots of the pillar; both ends of the upper support rod being soldered to the upper ring of the limitation corner, and both ends of the lower support rod being soldered to the lower ring of the limitation corner; each pillar with its clamped portion being inserted into the lower ring and the upper ring in sequence of its respective limitation corner; and the top being placed in the rack.

### Claim 2

A pillar insertion combination rack made in a rectangular or polygonal and a single layer or multiple layers includes an upper frame, a lower frame, a top, multiple pillars, multiple clamping members, and multiple connection rods; wherein the upper frame being made of a metal wire material in continuous form coiled at each corner to define an upper ring and running straight between any two corners to be performed a spot soldering at where both ends of the wire meet; the lower frame being made of a metal wire material in continuous form coiled at each corner to define an upper ring and running straight between any two corners to be performed a spot soldering at where both ends of the wire meet; the diameter of the upper ring being smaller than that of the lower ring; each pillar containing multiple sections with a circumferential slot defined between any two abutted section; the clamping member comprised of two identical halves facing each other secure the pillar at where the pillar to be inserted into the limitation corner by biting two circumferential slots of the pillar; the connection rod made of the same metal wire material in a waveform being disposed between and soldered to both of the upper frame and the lower frame with both of the upper ring and the lower ring at each corner being concentrically arranged; each pillar with its clamped portion being inserted into the lower ring and the upper ring in sequence of its respective limitation corner; and the top being placed in the upper frame of the rack.
