load generating apparatus for weight training device

摘要

The present invention relates to a case; A base which is positionally changeable on the floor in the case and is provided with a guide rail; A first connecting member having one end connected to the operating portion and the other end received into the case; A lifting / lowering part connected to the other end of the first linking member and movable up and down along a guide rail on an upper surface of the base; A load cell unit for measuring a load due to the movement of the lifting / lowering unit; A second connecting member having one end vertically connected to the load cell unit and the other end connected to the lifting / lowering unit; A fixed side pulley through which the second connecting member passes; A winch drum rotatably installed on the other side of the upper surface of the base and wound around the other end of the second linking member via the fixed side pulley on a circumferential surface; And a load motor for rotating the winch drum so that a load predetermined by the user is applied to the lifting and moving unit when the load measurement of the lifting and moving unit by the load cell unit is performed. This makes it possible to use all of the various types of muscle training equipment in common, as well as to enable miniaturization of the product by attaining modularization. In addition, the direction of the force to which the load cell is provided is always in the vertical direction So that accurate load measurement can always be performed regardless of the user's exercise habit or behavior.;
