Description

TECHNICAL FIELD [0001] The present invention relates to a weight control apparatus for a weight exercise apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weight load adjusting device for a weight lifting device used in a health club, a rehabilitation clinic, and the like, and more particularly, to a weight load adjusting device for a weight lifting device.

As the living standards of modern people improve their interest in health, life sports that protect their health through various exercises are becoming common.

Among them, there is a weight exercise device which improves the muscle strength through the exerciser, which is to perform a muscle exercise with respect to the upper body or the lower body by using a hand or a foot.

Such a weight exercise apparatus mainly adjusts the degree of exercise by adjusting a weight load of a weight according to an ability of an athlete.

That is, a weight rod interlocking with the movement handle is inserted and stacked in a multi-stage manner, and a pin engagement portion and a pin hole are formed in the weight rod so that the exercise person can select a weight weight load according to his / The support pin is inserted and held by the pin engagement portion of the weight of the weight at the weight load position and the pin hole of the weight rod among the stacked weights, and the weight load of the whole weight,

However, in the conventional weight lifting mechanism, the exerciser moves continuously while increasing or decreasing the weight load while moving the weight. At this time, the weight holding portion of the weight and the support pin inserted and held in the pin hole of the weight rod are separated, There is a problem that it is very inconvenient to adjust the weight because it is necessary to move while being inserted and supported while changing to the position of the load.

In addition, since the weight adjusting mechanism is located away from the bench on which the exerciser moves, the weight adjusting mechanism of the related art has a problem that it is more inconvenient for the exerciser to adjust the weight.

In addition, the conventional weight exercising apparatus has to adjust the weight exercise load step as much as the weight demand. For example, using four 10 kg weights, only a four-step weight exercise load of 10-20-30-40 kg can be combined, resulting in limited exercise efficiency.
