Weight training machine having a selector device that is operated easily and conveniently

Abstract

A weight training machine includes a support frame, and a selector. The support frame includes two parallel guide rods, a plurality of weights, and a drive shaft. The selector device includes a selector that is inserted into a gap between any two adjacent weights and connected to the drive shaft, and a reel mounted on the selector and having a retractable pull wire having a distal end secured to the support frame. Thus, the pull wire of the reel is kept at a straight state constantly during movement of the selector, so that the pull wire will not interfere with operation of the selector and will not tangle with the weights, thereby facilitating the user operating the selector, and thereby protecting the user's safety.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention The present invention relates to a weight training machine and, more particularly, to a weight training machine having a selector device. [0002] 2. Description of the Related Art [0003] A conventional weight training machine in accordance with the prior art shown in FIGS. 8 and 9 comprises a support frame, and a selector 86 mounted on the support frame. The support frame includes two parallel guide rods 81, a plurality of weights 84 movably mounted on the two guide rods 81, a drive shaft 89 movable between the two guide rods 81 and extended through each of the weights 84 to move the weights 84 upward and downward, and a drive belt 83 mounted on the drive shaft 89 to move the drive shaft 89. The drive shaft 89 has a plurality of through holes (not shown), and each of the weights 84 has a through hole 85 aligning with a respective one of the through holes of the drive shaft 89. The selector 86 is attached to the drive shaft ...

AI Technical Summary

Benefits of technology

[0007] The primary objective of the present invention is to provide a weight training machine having a selector device that is operated easily and conveniently.

[0008] Another objective of the present invention is to provide a weight training machine, wherein the pull wire of the reel is kept at a straight state constantly during movement of the selector, so that the pull wire of the reel will not interfere with operation of the selector and will not tangle with the weights, thereby facilitating the user operating the selector, and thereby protecting the user's safety.

[0009] A further objective of the present invention is to provide a weight training machine, wherein the two retaining plugs of the selector are retained in the respective retaining groove of the drive shaft, and the clamping opening of the selector is clamped on the drive shaft, so that the selector is combined with the drive shaft rigidly and stably, thereby facilitating the user operating the selector to move the weights smoothly.

Problems solved by technology

In addition, the connecting cord 87 is easily tangled with the weights 84, thereby interfering with operation of the weights 84, and thereby causing danger to the user's safety.
