Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hydraulic muscular strength strengthening device capable of training the muscular strength by a simple operation when taking a bath.

[0002]

[Prior art]

 Conventionally, when taking a bath, the most common method for strengthening a person's strength in a bathtub is to fold the elbows of both hands into a cruciform shape and push the hot water in the hands out of the gaps between the parents' fingers while pushing the two hands together. There was a method of using such pressure and a method of making it easy, although not always taking a bath, by bending the four fingers excluding the thumbs of both hands while bending them into a U-shape, and then pulling. Although these methods can be easily performed by children and adults, it took a considerable amount of time to be effective because the exercise was performed in a small area of the palm. In addition, since a spring is used as a device for training the strength of the arm, there is some danger and only the pulling force can be strengthened, but the expander was generally known.

[0003]

[Problems to be solved by the device]

 When using a method of strengthening the strength of the body that uses only the hands when bathing without using any equipment, the exercise range is narrow, and it is not possible to achieve a sufficient effect. The present invention solves these drawbacks, and in order to achieve a sufficient effect with the same exercise action as using the palm, generally, as a basis for strengthening physical strength, it is necessary to accumulate daily practice every day. Considering that it is important, considering the conditions for taking a bath, we needed a device that was easy and safe, had a simple structure and operation, and was unadjusted. The present invention has the above-mentioned conditions, and can be used by children and adults regardless of gender regardless of the practice of daily life such as bathing without changing to training wear. It is a device with the characteristics of, and aims to easily strengthen the arm strength.

[0004]

[Means for Solving the Problems]

 According to the hydraulic force strengthening device of the present invention, the grip portion is attached to the outside of one cylinder of the hollow tube, and the head portion is formed inward of the hollow tube and the other grip portion is formed outward from the opening of the other end. A characteristic feature is that a suction / drainage rod that can freely move inside the hollow pipe is inserted, and a flow hole that communicates from the inside to the outside is provided at the end of the hollow pipe.

[0005]

[Action]

 Since the present invention has the structure as described above, when taking a bath, in the bathtub, the grips formed on the hollow pipe and the suction and drainage rod are firmly held by the left and right hands to push out the air inside the hollow pipe. Sink in a bathtub in a standing state, and draw left and right. Then, the hot water enters the hollow tube through the flow holes, so once the water is filled to some extent, the hot water is pushed out through the flow holes while pressing each other. Since the flow hole is narrower than that of the hollow pipe, a resistance against running water, so-called water pressure, is naturally generated, and a considerable amount of physical force is required during the intake and drainage exercises, and this exercise operation is performed for a certain period of time. By repeating this a certain number of times, you can strengthen your strength. This exercise is not only for physical strength, but also for the pectoralis major muscles. At the same time, it is an optimal physical strength enhancement tool for business people who are busy with work every day and cannot afford to spend time again for sports. Moreover, since there is no need for adjustment, it is sufficient to set the exercise amount according to the physical strength of the individual to be used. Therefore, a single hydraulic force strengthening device can be used by children and adults. Also, because it is exercised in a bathtub, it also exerts buoyancy on the equipment, and since the exercise movement is simple, it is also suitable for function recovery training.

【Example】

 An embodiment will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of the present invention,

FIG. 2 is a sectional view of the finished product. The invention is

[Fig. 2] As shown in the cross-sectional view of the finished product, the hollow tube (1) and the gripping part (2) attached to the outside of one cylinder of the hollow tube (1), and freely moving inside the hollow tube. It is formed from a possible suction and drainage rod (5). And by molding each of these parts with a hollow structure, they can be easily submerged in a bathtub, are lightweight, and are low in cost. When the present invention is used, the grips (2) and (2a) are grasped by the left and right hands, and the movements of pushing and pulling are repeatedly performed to train the strength of the hand. In (2) and (2a), since a considerable gripping force is applied, it is advisable to have a partition reinforcing structure inside. The material is plastic, for example. The quality does not have to be deformed by general hot water temperature. The circulation hole (6) plays the most important role in the present invention. The flow holes (6) temporarily block the flow of hot water when the hot water flows in and out of the holes, thereby causing resistance. In other words, water pressure is generated here. Therefore,

As shown in FIG. 2, the flow hole (6) must have a structure smaller than the size of the hollow tube (1). The flow hole (6) is generally provided at the end of the hollow tube (1) from the top of the structure. Since the end of the hollow tube (1) corresponds to the so-called gripping part (2),

As shown in FIG. 3, a flow hole (6) may be provided in the grip portion (2). The flow hole (6) has the same function regardless of whether it is provided on the hollow tube side or the grip portion side. However, the number of circulation holes is not limited to one, and it is also possible to provide two or more circulation holes.Because it is possible to obtain a movement change called force adjustment depending on the number and size of circulation holes, it is possible to remove it by screwing. By arranging the grips with a wide variety of flow holes, it is possible to have a wide range of motion and to use them according to your physical condition. If a connection hole between the hollow tube and the grip portion is provided with a flow hole, the basic operation and effect of the present invention are the same even if they are integrally molded. In addition, in adjusting the force, in addition to the number and size of the flow holes, a gap is created at the connection between the hollow pipe (1) and the gripping part (2), and a flow hole control valve is provided. May be. In that case, by opening and closing the control valve, it is possible to bring about a change in the action of the through hole, and to strengthen either the pulling force or the pushing force. Even if the hollow pipe (1) and the gripping part (2) have a closed connection structure and the through hole is provided in the head part of the suction / drainage rod (5), the same effect can be obtained by the same action. it can. In the suction / drainage rod (5) that can move freely inside the hollow pipe, the head portion (4) formed in front of the suction and drainage rod (5) pulls and holds the gripping portions (2) and (2a) held by both hands to the left and right. The movement is to move inside the hollow tube, but its role is to push out and inhale the hot water in the hollow tube through the flow hole (6) and at the same time prevent the hot water from leaking backward. Its structure is There shall be no gap between the inner surface of the hollow tube (1). However, if hard materials are used together, slippage may be poor,

As shown in FIG. 3, a doughnut-shaped elastic member (7) having water resistance is provided at the rear of the head portion (4) so that a gap is not formed on the inner surface of the hollow tube (1). The hot water does not leak to the back when it is fitted with a special structure. In this case, there may be a gap between the head portion (4) and the inner surface of the hollow pipe (1). As another morphological example,

As shown in FIG. 4, by making the gripping parts (2) and (2a) into a T shape, one of them can be held by both feet, and the other can be held with the opposite hand, and by repeating up and down movements such as pulling up and down. You can also strengthen your wrist. or,

As another embodiment shown in FIG. 5, a hollow tube (1) and a suction / drainage rod (5) are provided in two, so that the gripping portions (2) and (2a) that connect them are held. You can train different muscle strengths. Furthermore, if a connecting rod for connecting the two hollow tubes is provided near the open part, the gripping part can be pushed by holding the fingertip on the connecting rod and grasping the palm of the hand. You can also strengthen your grip.

[0007]

[Effect of device]

 By using the present invention at the time of bathing, no extra time is required, and the basic physical strength such as grip strength, pectoralis major muscles, back muscles, and abdominal muscles is strengthened mainly by the strength of the arms, and the competition is strengthened even in games and as a man. You can make a fine upper body.
