Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an upper body strength training device, and in particular to a specialized training device (vertical press machine) that can strengthen the muscles of the chest and arms while sitting in a seated position. .

[Conventional technology]

In general, it is essential to exercise to maintain health and increase physical strength, and physical training outdoors or indoors is frequently performed. To perform this type of training indoors, machines and equipment are often used, and various equipment is provided for this purpose. These devices are designed to specifically train the muscles in each part of the body.For example, barbells and iron bells have been used since ancient times to train the muscles of the chest and arms, but in recent years, mechanical devices have been used to train the muscles of the chest and arms. BACKGROUND OF THE INVENTION Training equipment of various types are known, particularly from foreign imports or domestic equivalents. These devices suspend adjustable weights in a gate-shaped frame so that they can be raised and lowered, and the load of the weights is pulled by a weight connecting rope such as a wire, chain, or rope, so that muscles in specific areas can be trained. This is what I did.

[Problem that the invention attempts to solve]

However, according to the above-mentioned mechanized training equipment, when using it, the body must be laid down on a pedestal, face down, or in a standing position, and the hands and feet must be used.
Most training methods involve connecting weight ropes to the legs, torso, etc., and moving them for training.The preparation for such training positions is complicated and troublesome, and it is inconvenient that it cannot be used easily and conveniently. There is. Moreover, at present, almost all of this type of training equipment is used with its mechanical components exposed, so the feeling that the user receives from the mechanical structure lacks familiarity, making it difficult to use. In particular, it cannot be denied that it gives rise to a kind of fear, and is only used by extremely skilled people. In order to eliminate these drawbacks, metal parts are chrome-plated or mats are colored to make them as easy to get used to as possible, but the mechanical structure is exposed and the chain, wire, gears, etc. The appearance of the product, which includes cams and weights, makes it difficult for ordinary users, such as women, to get familiar with it.
It was only used by a few people who specialized in exercise. Furthermore, since conventional training equipment was installed in large rooms such as gymnasiums, there was no way to install it in small rooms, so this type of training equipment has become increasingly popular in indoor athletics. It was difficult to adopt the equipment.

Therefore, there is a need to provide training equipment that is familiar, compact, and easy to use for the general public, including women.

[Means for solving problems]

The present invention aims to provide a training device that solves the above problems, and includes a footrest provided at one end of a substantially straight frame.
A gate-shaped frame is erected at the other end, and a pair of left and right levers are rotatably supported at a predetermined length on both sides of the footrest, respectively, in a direction parallel to the frame, and near the lower end of the levers. One end of each cable is connected, and a grip is provided at the upper end, and a pair of left and right rotating wheels are rotatably supported on the frame between the footrest and the portal frame, and the rotating wheels are connected to each other. The other end of the cable is wound and fixed, a pair of left and right eccentric wheels rotatable coaxially with the rotary wheel are respectively supported on the frame, and both ends are fixed to the pair of eccentric wheels. In addition, a wound cable is provided, and an adjustable weight, which is loaded on the cable via a movable pulley, is suspended from the gate-shaped frame so as to be movable up and down. This upper body muscle strength training device is characterized in that a height-adjustable seat is provided, and each part of the rotary wheel, eccentric wheel, and weight is covered with a cover body.

[Effect]

According to the present invention, when a person sits on the seat, grasps the left and right levers with both hands, and pushes the left and right arms forward alternately, the weight of the weight loaded on the levers is initially reduced. In the final stage, 100% of the weight is applied, and by repeating this exercise repeatedly, the pectoralis major muscles are trained and strengthened. Moreover, since the device is configured to be trained in a seated position, it is compact and can reduce the installation area.
By covering the eccentric wheels and weights with a cover body, the sensation given by the mechanical structure can be removed, creating familiarity, and the general public such as women can easily and conveniently use the system.
