Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a brachial muscle strength training device, and more particularly to a specialized training device that can strengthen arm muscle strength 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 muscles in each part of the body.For example, barbells and iron bells have been used since ancient times to train arm muscles, but in recent years, mechanical training has become more popular. Devices are known, especially from foreign imports or domestic analogues. These systems train muscles in specific areas by suspending adjustable weights in a portal frame so that they can be raised and lowered, and by pulling the load of these weights through weight connecting cables such as wires, chains, or ropes. It has been made possible.

[Problem that the invention attempts to solve]

However, according to the above-mentioned mechanized training equipment, when using it, the user lies down or lies down on a stand, connects weight connecting ropes to the hands, legs, torso, etc., and moves them for training. Since training is mainly done in the form of a formal training position, the preparation for taking such a training position is complicated and troublesome, and it is inconvenient that it cannot be used easily or conveniently.
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 combination of cams, weights, etc. in its appearance makes it difficult for general users such as women to feel familiar with it, and it is only used by a few people who specialize in exercise. Furthermore,
According to conventional training equipment, it was installed in large rooms such as gymnasiums, and there was no way to install it in small rooms, so recently we have rented a room in a building to hold various training classes. In some cases, it was difficult to adopt this type of training 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-mentioned problems. An arm extending horizontally from the vicinity of the shoulder of the stand plate to both the left and right sides, an elbow rest plate fixed to each arm in a horizontal position, and an arm each pivotally supported by the arm near the elbow rest plate. a rotatable rotary wheel; a lever projecting upward from the rotary wheel and having a rotatable grip at an end; an eccentric wheel rotatably supported in conjunction with the rotary wheel; A cable of a certain length whose end is fixed to the cable, an adjustable weight that is loaded onto the cable via a movable pulley, and a cover body that covers the rotating wheel, the eccentric wheel, and the weight. This is an upper arm strength training device.

[Effect]

According to the present invention, the user sits on the seat, fixes the body with the backrest plate and the headrest plate, puts both elbows on the elbowrest plate, and grasps the grip of the lever with both hands. It involves repeating the action of tilting or pulling the lever forward, and when the lever is tilted, the weight is being applied to the arm, so the weight is applied to the arm.
Arm muscle strength, especially the triceps or biceps, is increased.

One end of the cable 4e is fixed to the cable 4e, and the cable 4e is passed through the hojo 5a and wound around the rotating wheel 4c, and the other end is fixed to the rotating wheel 4c. The rotary wheel 4c is pivoted in a direction different from that of the embodiment described above, and the eccentric wheel 4d is also pivoted in a direction different from that of the embodiment described above. Furthermore, a cable 4h, one end of which is fixed to this eccentric wheel 4d, is attached to a sheave 4k.
On the other hand, the way of multiplying is different. The other configurations are basically the same as those of the previous embodiment. In this second embodiment, by lifting and rotating the lever 6 rearward,
It is used to train the biceps.

Next, the operation of the above embodiment will be explained. In FIG. 1, a person is seated on the seating portion 3, and when the person is seated, the height of the seat plate 3e can be adjusted to best suit the person. To adjust the height of the seat plate 3e, pull the seat plate 3e toward you as shown by the imaginary line in FIG. 3h, move the seat plate 3e up and down in the pulled out state, and rotate the seat lever 3d counterclockwise to insert the pin 3g into the through hole 3h that matches the desired height. The pin 3g is inserted into the through hole 3h to fix the seat lever 3d. In this way, when a person is seated on the seat 3, puts their feet on the footrest 7, and is ready for training, the next step is to grasp the left and right grips 6d, 6d with both hands, and press the levers 6, 6 at the same time. Or push forward alternately. When the lever 6 is tilted forward, the cable 4e moves the rotary wheel 4c to the shaft 4.
The eccentric wheel 4d is rotated counterclockwise around b as the center, and at the same time, the eccentric wheel 4d is rotated counterclockwise. The eccentric wheel 4d pulls the cable 4h, and the cable 4h has a constant length, so
The movable pulley 2g descends, and the weight 2b of a predetermined weight selected by the strip 2e rises. In other words,
Since the weight of the weight 2b is applied as a load to the lever 6, extending the arm requires a force to resist this load, and the muscles of the arm, particularly the triceps brachii, work.

On the other hand, for training the biceps brachii, the lever 6 is configured in a state in which it is tilted forward of the arm 5 as shown in FIG.
6c with both hands, and rotate the levers 6, 6 left and right simultaneously or alternately backward. In other words, the exercise is the opposite of that for training the triceps. In this way, by repeatedly pushing both arms backward or pulling them from front to back at the same time or alternately, the triceps or biceps can be trained.

[Effect of idea]

According to the present invention described above, a person sits on the height-adjustable seating part, fixes the body, grasps the grip part, puts the elbow on the elbow rest plate, and pushes the lever forward or lever By repeating the movement of pulling from front to back with both arms simultaneously or alternately, you can effectively train the muscle strength of your triceps or biceps, so you can prepare to get into a training position. This simplifies the process, allows the body to be held stable, makes training easier, and allows the entire device to be made more compact. Furthermore, since the load of the weight is applied to the cable via a movable pulley and eccentric wheels are connected to both ends of the cable, only one weight is required to apply the load to the left and right levers.
Since only one adjustment is required, the configuration is simplified compared to the case where a load is applied to the left and right levers individually, and the trouble of adjustment can be omitted.
In addition, since the mechanical components are covered with a cover body, safety is provided by preventing injuries caused by accidental contact with parts of the body, and also eliminates the impression of exposed training equipment. This, combined with the fact that the cover body can be colored and patterned, gives a soft image.
Since it makes the general public, such as women, feel familiar, the desire to use it is increased, and it is suitable for indoor athletics.
