Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a pressure therapy device mainly for the back surface, which is capable of strongly pressing an indenter against the human body.

(Conventional technology) Pressure therapy machines are used to relieve muscle stiffness, relieve muscle pain and fatigue, treat various diseases by applying pressure to so-called pressure points, promote blood circulation by rubbing the skin, etc. It is commonly used for the purpose of Various types are commercially available, including those that vibrate.

Among these pressure therapy devices, those that simply press have one or several indenters protruding from a plate-like frame, and the indenters are pressed by applying pressure to stiff areas or acupuncture points, or by placing them on the back. The main method of use was to place one's weight on it and use it as a substitute for acupressure.

(Problem that the invention aims to solve) The secret of acupressure treatment is to press gently with the thumb placed on the human body, and then press firmly two or three times at the end, and this final strong pressure is the most effective treatment. Although it is effective and makes the patient feel refreshed, continued strong pressure causes pain in the fingers and puts pressure on the shoulders, resulting in severe fatigue.

When using a conventional pressure therapy device, the indenter presses against the human body instead of the thumb, so the thumb does not hurt, but it also requires a lot of arm strength to apply strong pressure, which causes damage to the arms and shoulders. The problem was that I was tired and could not use it for a long time.

Furthermore, if you are trying to apply pressure to your back or lower back by yourself, it is almost impossible to do it with your own hands, so you can place a pressure therapy device on your back, lie on your back, and put your weight on the indenter. Because it was used, the pressing force was determined by the body weight, and it was not possible to press any harder.

The purpose of this invention is to provide a pressure therapy device that can obtain a strong pressing force with a light force, and in particular can press strongly on the back side by oneself, in order to solve the problems of the conventional products as described above. be.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides one or more pairs of bilaterally symmetrical indenters protruding from the upper surface of the hollow body, and protruding from the center of the indenters. The indenter is fitted so that it can protrude from the tip of the indenter, and the protruding indenter is positioned so that the tip of the indenter and the tip of the protruding indenter match under normal conditions, and the protruding indenter is further urged downward by a spring. At the same time, a pair of left and right screw levers for protruding the protruding indenter are supported by providing a fulcrum within the main body, and the point of action of the screw levers is provided at or near the lower end of the protruding indenter, Furthermore, this screw lever is connected directly or removably at an appropriate position and protrudes long from the outside of the main body, and is bent or curved upward to serve as an operating rod, so that the normal position of this screw lever can be adjusted. This pressure therapy device is equipped with a lever spring that acts on the lever for holding the device.

In addition, there are two cases in which the fulcrum of this screw lever is set at a position close to the point of action between the point of action and the operating section, and another where the tip of the screw lever is set as the fulcrum and the point of action is set as the fulcrum between the fulcrum and the operating section. In some cases, it may be located close to the
In the former, when the operating part is pushed outward, the point of action rises and the protruding indenter is ejected; in the latter, when the operating part is pulled inward, the point of action rises and the protruding indenter is ejected, and the direction of operation is different. The purpose of the action is the same.

(Function) When you place this pressure therapy device on the floor or tatami surface with the indenter facing upward and lie on your back so that the indenter hits the pressure points on your back or waist, the indenter will absorb your weight in the same way as with conventional pressure therapy devices. It will press pressure points once. Next, you can either hold the control stick that extends upward to the left and right with both hands, or place your arm on the control stick and push it outward, or hold the control stick with both hands or hold it in your arm and pull it inward. , by extending the tip of the control stick configured in a rear-addition type while lying on your back, extending it above your body, holding the tip with the opposite hand and pushing outward, etc. The point of action of the lever pushes up the lower end of the protruding indenter, and the protruding indenter protrudes from the tip of the indenter to strongly press the acupuncture point. By repeating this operation of the lever two or three times, it is possible to achieve the same pressing effect as the last strong push in the case of acupressure without having to bother others.

(Embodiment) First Embodiment An embodiment will be described below with reference to the drawings.In FIGS. 1 to 3, 1 is a main body, and the upper and lower bodies together have a hollow interior.

Reference numeral 2 denotes an indenter, which is provided in two pairs protruding symmetrically from the upper surface of the main body 1.The tip is rounded into a spherical shape, the inside is hollowed out from the back to form a cavity 2a, and a through hole 2b with a small inner diameter is formed at the center of the tip. is provided.

3 is a protruding indenter, and a flange 3a that fits into the cavity of the indenter is attached to the lower end of the cylindrical main body that fits into the through hole 2b of the indenter.
The spring 4 is inserted into the gap between the inner diameter of the cavity of the indenter 2 and the outer diameter of the main body of the protruding indenter 3, and presses the collar 3a of the protruding indenter 3 to form a protruding indenter. 3 to give a pressing tendency, and the protruding indenter 3
The position is determined when the lower end of the indenter comes into contact with a retaining ring 5 fitted into the cavity 2a of the indenter, and at this time, the tip of the indenter 2 and the tip of the protruding indenter 3 are configured to substantially coincide with each other.

Reference numeral 6 denotes a lever lever, which is provided as a pair symmetrically, with a vertical rod 6a spanning the center of the back surface of the two indenters 2, 2 on one side within the main body 1, and a vertical rod 6a extending from the center of the length of this vertical rod to the outside of the main body 1. A horizontal rod 6b extending in a T-shape toward the end and a fulcrum shaft 6c perpendicular to the horizontal rod 6b are welded to a position close to the outer end of the main body 1 of the horizontal rod 6b and integrated, and both ends of the vertical rod 6a are integrated. This vertical rod 6a is bent up so that its tip is in contact with or near the center of the lower end of the protruding terminal 3.
The tip of the bent end is the point of action 6d, and both ends of the fulcrum shaft 6c are rotatably supported by bearings 7, 7 provided on the main body 1, and a torsion coil type is attached to the fulcrum shaft 6c. The lever lever spring 8 is applied to the horizontal rod 6b and the bearings 7, 7, and the point of action 6 is
d is at the lowest position, that is, the protruding indenter 3 is not pushed up, and the tip of the horizontal rod 6b is located near the outer end of the main body 1.

Reference numeral 9 designates an operating rod, which is made by bending a tube or rod into a C-shape and providing a grip 9a at the tip and a socket 9b at the base end, and this socket 9b is attached to the tip of the horizontal rod 6b of the screw lever 6. It is fitted so that the operating rod 9 is bent upward and inward.

The pressure therapy device having the above configuration is placed on the floor or on a tatami mat with the indenter 2 facing upward, and as shown in FIG. When you place your body between them and place the indenter 2 on the pressure points on your back or lumbar region and lie on your back as shown in Figure 2, the symmetrically placed indenters 2 will apply your weight to the pressure points on both sides of your spine. An initial light pressure treatment is performed by applying pressure, and then holding the grips 9a of the control sticks 9, 9 with both hands, or pushing the control sticks 9, 9 with the outside of your arm to spread them outward in the direction of the arrow. Then, as shown in FIG. 3, the screw lever 6 lifts the vertical rod 6a at the tip using the fulcrum shaft 6c as a fulcrum, and
The point of action 6d pushes up the lower end of the protruding indenter 3, and the protruding indenter 3 protrudes from the center of the indenter 2 against the spring 4 to strongly press the acupuncture points of the human body.

The pressing force of this protruding indenter 3 is determined by the distance from the fulcrum shaft 6c to the point of action 6d and the distance from the fulcrum shaft 6c to the operating rod 9.
The force applied to the force point is amplified by the ratio of the distance to the force point (the point where force is applied), and a powerful pressing force of the protruding indenter 3 can be obtained.

When the pressure on the operating rod 9 is released, the protruding indenter 3 descends due to the body weight and the repulsive force of the spring 4 and returns to its original position, and the lever lever 6 and the operating rod 9 are moved to the lever spring 8. Therefore, it will be returned to its former position.

By repeating strong pressure with the protruding indenter 3 several times in this manner, the pressure therapy effect is dramatically increased, and a pleasant sensation due to strong stimulation can be obtained.

Further, by removing the left and right operating rods 9, 9 from the socket 9b, pressure therapy can be performed anywhere on the body in the same manner as with conventional pressure therapy devices commonly used.

Second Embodiment FIGS. 4 and 5 show another embodiment, in which an operation rod 9c is added to the tip of the operation rod 9 shown in the first embodiment and is configured to extend above the body. Then, lie on your back without the refilling operation stick, add the refilling operation stick later, hold the left side refilling operation stick with your right hand, and push or pull it.
Similarly, the right operation stick is held in the left hand and pushed or pulled, and the operation is performed one at a time with the opposite hand to make it easier to operate, and other aspects are the same as in the first embodiment.

(Effects of the invention) As explained above, this invention has a simple structure that applies the principle of a screw, and a large pressing force can be obtained with a small force, reducing labor. Since it can perform strong pressure therapy, it is possible to perform pressure therapy that is highly effective and provides a pleasant sensation without bothering others, and if the operating stick is detachable, it can be used as a pressure therapy device similar to conventional products. It is possible to provide a pressure therapy device that is convenient and has excellent practical effects, such as being able to have a compact form for storage and transportation.
