Abstract

Disclosed is a weight-training machine having an independent power generating function, which may improve the exercising effect, control the weight caused by a solenoid without external power together with keeping a conventional button manner and eliminate a space limitation for installation of the machine. The weight-training machine has an independent power generating function so as to minutely adjust an exercising load without supply of external power. An operation distance between a fixing plate and a push button of a fixing device is minimized to allow one-touch manipulation. The solenoid may be operated with a lower electric energy. Thus, stacks are not shaken in right/left or front/rear direction on the basis of the fixing plate and the insert groove when a stack selected by the fixing plate and stacks upon the stack are moved up and down at the same time.

Claims

1. A weight-training machine having an independent power generating function, which includes a plurality of stacks moving up and down by means of a pair of guides mounted vertically, a button unit disposed at a front center of the stacks and having the number of solenoid buttons corresponding to the number of the stacks and buttons inserted into insert holes of the stacks, and a wire guided by pulleys mounted to a frame,

wherein a solenoid unit having the solenoid buttons is separated from the button unit so that the solenoid buttons are installed to a position adjacent to heads of the buttons, wherein the buttons are moved forward and backward electrically or manually, wherein a pair of generators having a rod shape are installed at both rear sides of the stacks so as to be parallel to each other vertically with a predetermined distance, and wherein a power supply is installed below the generators so that the power supply is electrically connected to the generators and the solenoid unit.

2. The weight-training machine according to claim 1, wherein the generator includes a pipe having a coil wound in contact with an inner side thereof, and a magnetic rod combined to be movable in a length direction along inside of the coil and composed of a plurality of permanent magnets so that positive and negative poles are alternately laminated, whereby the generator generates power by means of movement of the permanent magnets when reciprocating in the coil in a length direction along a selected stack.

3. The weight-training machine according to claim 1, wherein the power supply includes a converting switch provided with electric power selectively from the generators and an external power source, an inverter for converting AC supplied from the converting switch into DC, and a charger for charging the supplied DC.

4. The weight-training machine according to claim 3,

wherein a sensor for sensing operation of the solenoid button is mounted to the solenoid unit, wherein a sensor is installed to a controller to operate a selected solenoid button so that the button is inserted into an insert groove of the stack, wherein the sensor senses manual operation of the solenoid button to make the controller display a current exercising weight, wherein the sensor senses a user to be in an exercising position so that the controller is operated when the user is in the exercising position and the power is automatically isolated when the user takes off from the exercising position.

5. The weight-training machine according to claim 1, wherein a generator is further installed to one of the pulleys.

6. The weight-training machine according to claim 1, wherein a sensor for sensing operation of the solenoid button is mounted to the solenoid unit, wherein a sensor is installed to a controller to operate a selected solenoid button so that the button is inserted into an insert groove of the stack, wherein the sensor senses manual operation of the solenoid button to make the controller display a current exercising weight, wherein the sensor senses a user to be in an exercising position so that the controller is operated when the user is in the exercising position and the power is automatically isolated when the user takes off from the exercising position.
