Weight adjustment by means of a ramp

Abstract

A weight adjuster on a weight station which has a support frame on which a rotatably mounted guide frame is attached which has rails on which the weight can be moved in the longitudinal direction by means of pulleys or sliding elements, and the angle of the guide frame is continuously adjustable by means of an actuator means and therefore effects a change in the load on the rope. The rope can supply electrical power, and a training program can be optimized by means of buttons, a force sensor, a rotational-speed sensor, a vibration generator and the controller.

1 . A weight adjuster, wherein the weight adjuster is connected to a weight station and comprises a support frame on which the guide frame with the rotary bearing and the guide pulley is fastened, and attached to the guide frame are rails on which the weight is movable, and also guided and supported, in the longitudinal direction according to the lift by means of pulleys or sliding elements, and an actuator means is fastened to the guide frame, which actuator means makes the guide frame continuously adjustable through the angle, and the weight is fastened to the rope which is fed past or deflected at the guide pulley and is fastened at the other end to the training means and has an angle measurement means. 
     
     
         2 . The weight adjuster according to  claim 1 , wherein the guide pulley is attached such that the rope pulls parallel to the rail and centric between the rails independent of the angular position of the guide frame. 
     
     
         3 . The weight adjuster according to  claim 1 , wherein the rail forms the guide frame and acts as a ramp which can be swiveled from a vertical position up to an almost horizontal position. 
     
     
         4 . The weight adjuster according to  claim 1 , wherein the rope comprises an integrated electric power and data cable which can be connected to the button, the force sensor, the display and the controller. 
     
     
         5 . The weight adjuster according to  claim 1 , wherein the guide frame can be adjusted during training with regard to the angle by means of the buttons or automatically by means of an algorithm in the controller, and the button can be a piezo button having a radio module. 
     
     
         6 . The weight adjuster according to  claim 1 , wherein the can be detected by a rotary-speed sensor and values are transmitted to the controller. 
     
     
         7 . The weight adjuster according to  claim 1 , wherein the rope absorbs the frequency generated by the vibration generator at the deflection pulley and transmits it specifically to the training means. 
     
     
         8 . The weight adjuster according to  claim 1 , wherein the training means comprises one of the following elements, which are a grip bar, a pull or push rod, a padded bar, a padded plate, a foot plate, a strap, a barbell and the like. 
     
     
         9 . The weight adjuster according to  claim 1 , wherein the guide frame can be swiveled hydraulically, electrically or manually by means of the actuator means and can be locked in any position, and the actuator means is fastened in a rotatably mounted manner to the support frame on the one side and to the guide frame on the other side. 
     
     
         10 . The weight adjuster according to  claim 9 ,
 wherein the actuator means is a cylinder or a rack with a pinion or a rotary motor with worm gear, and attached thereto or therein is an angle measuring means or length measuring means which acts electronically or mechanically.   
     
     
         11 . The weight adjuster according to  claim 1 , wherein a hoist serves for elongating the lift by means of the hoist pulley which is attached to the weight and effects the lift. 
     
     
         12 . The weight adjuster according to  claim 1 , wherein the rope is guided at the deflection roller and is optionally attached to a cam disc or an eccentric. 
     
     
         13 . The weight adjuster according to  claim 1 , wherein the guide frame is supported by a gas spring which can be blocked, or a ratchet lock or a worm gear provides for the locking. 
     
     
         14 . The weight adjuster according to  claim 1 , wherein the weight adjuster has a damper, and the weight can consist of lead and can be segmented for assembly and can have a cover. 
     
     
         15 . The weight adjuster according to  claim 1 , wherein a curved measuring rail or a mark is located at the guide frame and curved measuring rail or a mark is located at the support frame.
