Description

  The present invention relates to a strength training machine for strengthening muscles such as a chest, a shoulder, an upper limb, and a lower limb in a strength training machine for powering up muscle strength.

  As a conventional apparatus, a muscular strength training apparatus including components such as a grip, a frame, a lever, a weight suspension frame, a weight, a counter arm, and an assist bar is disclosed.

  In the conventional apparatus, when the grip is pushed, the assist bar can be kicked with the foot, so that it is possible to handle a larger amount than the amount of weight that is usually lifted only by the force of the arm, and more effective muscle training.

However, the conventional apparatus is an apparatus that only performs a chest press even if an assist bar is provided, and cannot perform two types of training, a leg press and a chest press, with a single apparatus.

When the operation arm 4 or the footrest portion 5 is pushed and moved in the advanced state in which the pin 53 is fitted into the hole 55 of the hole piece 52, both of them move in synchronization. Even if the trainee loses the pressing force to one member (for example, the operation arm 4) in the operation arm 4 or the footrest portion 5, if the other member (for example, the footrest portion 5) moves, the movement is one side. Transmission to the member while the member continues to move.
When trying to move one member of the operation arm 4 or the footrest portion 5, since the beginning of movement is heavy, the other member is moved to assist the initial movement of one member, and the initial movement of one member is lightened.

  A load latch 7 for coupling / releasing the load device 6 and the operation arm 4 and coupling / releasing the load device 6 and the footrest 5 is provided, and the load latch 7 is appropriately coupled / released. It can be applied to muscle strength training in which leg press and chest press training can be performed simultaneously or separately.

  The frame 1 is provided with an operation arm shaft 12 to which the lower portion 4a of the operation arm 4 is attached and a footrest portion shaft 13 to which the foot frame 19 of the footrest portion 5 is attached. The operation arm side arm 23 is erected, the foot plate side arm 27 is erected on the footrest shaft 13, and the upper end 23a of the operation arm side arm 23 and the upper end 27a of the foot plate side arm 27 are connected to the operation side cord. The body 44 is connected, the middle of the operation side cable body 44 is hung around the moving pulley 43, and the central shaft 45 of the moving pulley 43 is connected to the load device 6, so that the upper limb training is performed by one muscular strength training machine 26. Can be applied to a convenient strength training machine that is space-saving, inexpensive, and convenient.
