Abstract

The present invention is a weight stacking plate structure for a weight training device comprises of a hoisting plate disposed at the direct upper aspect of an top plate of the device, a fixing section is perpendicularly mounted at the central area of the hoisting plate for suspending a steel rope, thread teeth with a fitting nut are disposed at the proper area at the upper end of a selector rod; the first position aligning hole of the said selector rod is an oval design provided for an alloy steel screw to penetrate through the frontage of the top plate for locking in thereby to fasten the selector rod not to rotate transversely so as to avoid the transverse deviation of the position aligning hole on the rod and to avoid the occurrence of causing the selector rod to fall due to the neglected and loosened nut during operation.

Claims

1. A weight stacking plate structure utilizes a steel rope mounted on a pulley set of a body and two guide rods fitted with the two sides of a body to conduct the up-and-down operation of several weight stacking plates for people to do weight lifting training;

the said guide rods on two sides are inserted inside two guide tubes disposed on two sides of an top plate, the said top plate is situated at the top end of several weight stacking plates;

a selector rod disposed with several position aligning holes penetrates through the top plate and several weight stacking plates to enable several position aligning holes on the selector rod to just align with the holes disposed on several weight stacking plates for the optional insertion of an insert pin;

the features of the present invention are;

a hoisting plate is disposed at the direct upper aspect of the top plate, a fixing section is perpendicularly mounted at the central area of the said hoisting plate for the suspending of a steel rope;

thread teeth are disposed at the proper area at the upper end of the selector rod and are fitted with a nut to be used for adjusting the ascending and descending of the selector rod penetrating through the top plate and several weight stacking plates so as to correct the problem of incapable insertion of the insert pin caused by the misalignment between the holes disposed on the weight stacking plates and the position aligning holes disposed on the selector rod due to the thickness difference of the weight stacking plates;

the first position aligning hole is designed as an oval shape for locking in an alloy steel screw penetrated through the frontage of the top plate thereby to fasten the selector rod not to rotate transversely to avoid the transverse deviation of the position aligning holes on the selector rod and the occurrence of causing the selector rod to fall due to the neglected and loosened nut during operation.

2. The weight stacking plate structure of a weight training device according to claim 1, wherein two movable nylon tubes are mounted inside the guide tubes on the two sides of the said top plate and fastened in position by means of two C-shaped retainers to correct the deviation of the guide rods and to avoid the damage caused by the serious friction between the guide tube and the guide rod.

3. The weight stacking plate structure of a weight training device according to claim 1, wherein, when the selector rod is adjusted, several selected weight stacking plates can be bundled up into one unit to avoid generating a lot of noise and to reduce the breaking situation both caused by the impact among the weight stacking plates during the operating of the machine.
