Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a deltoid muscle training machine.

BACKGROUND TECHNOLOGY In general, business activities that provide instruction in various physical training programs under the name of so-called sports classes or clubs are becoming more and more popular, but these types of organizations require various types of training equipment. In general, strength training has traditionally been carried out by lifting and lowering heavy objects such as barbells and iron bells, but this type of strength training is generally practiced by sports experts. It is something that only amateurs can use, and it is dangerous, so it cannot be used easily by amateurs.

Therefore, recently, muscle training has become mainstream by configuring a frame that raises and lowers a weight that can be arbitrarily selected, and pulling a rope connected to the weight.This method is low risk and easy for anyone to train. Since it is possible to easily perform desired muscle strength training, it has become popular to equip sports clubs and the like.

Problems that the invention aims to solve However, it is natural that various variations can be constructed as a means of raising and lowering weights within the frame and applying the weight to the muscles of desired parts of the body to be trained. However, conventional training machines of this type generally cannot achieve effective strength training. I mean,
Since many training machines are designed for sports professionals and assume that the professional knows how to use the machine, amateurs will not be satisfied unless they are familiar with or are instructed how to use the machine. The problem lies in not being able to do strength training. For example, when training upper body muscles such as the pectoralis major, deltoid muscles, and biceps brachii, the lower body should be immobilized so that it hardly moves, but unless there is a way to sufficiently immobilize the lower body, amateurs However, there are problems such as the inability to effectively use off-the-shelf training machines.

Furthermore, since this type of training machine is designed for sports professionals, most of the machines are used without any kind of cover, with the moving parts such as the mechanism for raising and lowering weights and the rotating mechanism exposed. Therefore, amateurs may be at risk of injury by touching the moving parts, and women in particular may find it difficult to understand the structure and movement of the exposed mechanical parts, making them difficult to access even when they want to train with the machine. There was a certain aspect that had to arise.

In view of the above circumstances, the present invention aims to provide a machine that allows even amateurs to comfortably, easily, appropriately, and effectively perform muscle training.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a gate-shaped frame erected on a base, a counterweight that is movable up and down on the gate-shaped frame, and covered with a cover body. , a height-adjustable seating section is provided on one side thereof, a footrest is provided on the base at the left and right lower portions of the seating section, and one end is pivotally supported by the portal frame near the shoulder section so as to move forward and backward. A pair of rotatable left and right arms is provided, a grip portion is provided at the other end of each arm, and a stopper for regulating the rotation stroke and the load of the counterweight are applied to the rotation shaft portion of the arm. A deltoid muscle training machine was constructed in which levers were provided, the levers and the counterweight were connected by cables via eccentric sheaves, and the cables and eccentric sheaves were covered with cover bodies.

Effects According to the above configuration of the present invention, when a person who wants to train sits on the seat with his or her back against the backrest, grips the grip with both hands and rotates the arm from above to below, the arm moves. The weight from the weight is applied to the shaft, allowing you to train your muscular strength.

In this case, levers 12, 12 (only one side is shown in the figure, however, see FIG. 7) protrude inside the cover body 8 on both left and right sides, sandwiching the gate-shaped frame 2. , 12 are provided with stoppers 13, 13 (same as above), and stoppers 14, 1 with which the stoppers 13, 13 abut are provided.
4 (same as above) is provided to protrude from the portal frame 2. Further, a pair of left and right second levers 15, 15 (same as above) are provided on the rotation shaft 9 and protrude into the cover body 8, sandwiching the portal frame 2 below the lever 12.
One end of the cables 16, 16 (same as above) is fixed to the ends of the cables 5, 15, respectively. Each arm 10 has counterweights 17, 17 suspended below the rotating shaft 9 to reduce its own weight. Said cable 1
6, 16 are pulleys 18, 1 pivotally supported on the base 1
8, 18a, and 18a (same as above) to the front of the base 1, and is pivotally supported on the front of the base 1.
19, and is fixed via rope ends 20, 20. As shown in FIGS. 5 and 6, the pair of left and right sheaves 19 are independently supported by shafts 22, 22 supported by bearings 21, 21, respectively, and eccentrically supported by the shafts 22, 22. It is connected integrally with the eccentric sheaves 23, 23 by bolts 24 and nuts 25. The ends of the other cables 26 are connected to the peripheral edges of the eccentric sheaves 23, 23 by rope ends 27, 27, respectively.
The cable 26 extends into the portal frame 2 via pulleys 28, 28 (see FIG. 7), which are coaxial with the pulley 18 and are also provided with a shaft support.

In addition, 33 is a footrest provided on both sides of the base 1, 34 is a cover body that covers the eccentric sheaves 23, 23 and pulleys 18, 18, and 35 is a seat belt that hangs on the front part of the base 1. It is fixed to a U-shaped frame 36 provided therein.

Next, the operation of the above embodiment will be explained. 1st
As shown by the imaginary lines in FIG. 3, a person 37 adjusts the height of the seating portion 4 as appropriate, sits down facing the gate-shaped frame 2, and places his or her feet on the footrests 33, 33.
The thighs are fixed with the seat belt 35. Then, extend both arms upward and grasp the gripping parts 11, 11 of the arms 10, 10 with both hands, respectively.
Push 0 forward. When the arm 10 tilts forward, the load of the weight 5 is applied to both arms until the pivot shaft 9 rotates and the lever 12 hits the stopper 14 of the portal frame 2 and the arm 10 stops. That is, as shown in FIG. 7, the arms 10, 10 and levers 12, 12 are rotated simultaneously,
is pulled upward, the sheaves 19, 19 rotate counterclockwise, and the eccentric sheaves 23, 23 rotate counterclockwise together. The cable 2 is attached to the eccentric sheaves 23, 23.
6 is fixed, the cable 26 is pulled loosely at the beginning and becomes stronger in the middle, thereby lowering the movable pulley 29. Since the load of the weight 5 is applied to the movable pulley 29 via the cable 30, the load is applied to both arms. Furthermore, when the arms 10, 10 are tilted forward as much as possible and then both arms are raised upward, the force of the weight 5 acts, causing the levers 15, 15 to rotate downward, and the arms 10, 10 to move upward. Rotate and return to the original state. In this way, by repeatedly raising and lowering both arms so as to rotate them around the shoulders, it is possible to effectively strengthen the muscle strength of the deltoid muscles.

In addition to the aforementioned training in which both arms are raised and lowered at the same time, training in which both arms are raised and lowered alternately can also be performed.

Effects of the invention According to the invention explained above, a person who uses the deltoid muscle training machine places his or her feet on the footrest,
By sitting down on the seat and grasping the grips with both hands, you can assume a posture or position that stabilizes your lower body and provides the most effective training, and from which you can rotate both arms at the same time or alternately. Since the load of the weight is applied during the rotation, not only experts but also amateurs can easily and mechanically strengthen the deltoid muscle effectively. Furthermore, since the counterweight and the movable parts for raising and lowering it are covered with a cover body, the person doing the training or those in the vicinity will not be injured by touching them unnecessarily, and the movable part will be hidden and the body will not be injured. It stains easily and allows you to train comfortably. It is also clear that it is effective as a strength training machine for not only the deltoid muscles but also the latissimus dorsi and teres major muscles.
