Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a pressure therapy device that can strongly press an indenter against a 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 indenter is applied to stiff areas or acupuncture points to press, or by applying pressure using your body weight. Its main use was as a substitute for acupressure by applying pressure.

(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 protrusion 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 press hard, which can cause fatigue in the arms and shoulders. The problem was that it could not be used for a long time.

The purpose of the present invention is to provide a pressure therapy device that can obtain strong pressing force with a light force in order to overcome the drawbacks of the conventional products as described above.

(Means for solving the problem) In order to achieve the above object, the present invention has an indenter shaft having an indenter at the lower end, which is passed through a plate-shaped frame so that the indenter is located on the back side of the frame. This pressure therapy device is provided with a lever on the top surface of the frame that is biased upward by a spring to push down the indenter shaft, and a handle that can be held with one hand to apply the indenter to the human body.

(Operation) Hold the handle of the pressure therapy device with one hand and press the indenter protruding from the back against the human body to apply initial pressure. Next, when the lever is pressed down with the other hand, the pressing force is amplified by the force of the lever, pushing down the indenter shaft, and the indenter at the lower end of the indenter shaft presses against the human body with a strong force. In this way, by repeatedly pushing down the indenter shaft by moving the lever up and down two or three times, a pressing effect similar to that of pressing strongly at the end of finger pressure can be obtained with a small amount of force.

(Example) An embodiment will be described below based on the drawings.

Reference numeral 1 denotes a frame made of plate-shaped plastic or metal, and has a hole 2 approximately in the center thereof through which the indenter shaft is inserted. Reference numeral 3 denotes an indenter, which is made of an elastic body such as a spherical hard rubber, and has a core metal 4 inside, and an indenter shaft 5 is screwed onto this core metal. Adjust position.
Reference numeral 6 denotes a restriction plate, which is screwed onto the upper side of the indenter of the indenter shaft 5 and serves as a restriction to prevent the indenter 3 from entering excessively when used in a soft place such as the abdomen of the human body, and to prevent the indenter from rotating. He plays Natsuto's role.

7 is a screw holder, bend both sides of the metal plate,
Further, only a portion of the upper side is folded back parallel to the lower side, and this folded portion has a rectangular cross section, and the bottom side is fixed to the frame 1. Through-holes 8, 8a through which the indenter shaft 5 is inserted are provided at the bottom and top sides of the rectangular section, and the through-holes 8, 8a are aligned on the same axis as the hole 2 of the frame 1.

Further, elongated holes 9, 9a are bored on both sides of the screw receiving fitting 7 corresponding to the axes of the through holes 8, 8a.

Reference numeral 10 denotes a screw lever, which is made by bending a metal plate into a rectangular groove shape, with the open part facing downward, and both side plates covering the outside of the screw receiving fitting 7.
is rotatably supported at the tip of the screw holder 7 by a fulcrum pin 11 that passes through the side plate.

12 is a spring that connects the through hole 8 of the screw holder 7;
An indenter shaft 5, which is inserted between the bottom side and the top side between 8a and the through holes 8 and 8a from the hole 2 of the frame 1, passes through the center of the coiled spring 12.

Reference numeral 13 denotes a screw pin, which is inserted through both side plates of the screw lever 10 and at the same time into the elongated holes 9, 9a of the screw receiver 7, receives the upper end of the spring 12, and is provided so as to pass through the indenter shaft 5. The spring 12 pushes up this screw pin 13, and the screw pin 13 pushes the screw lever 10 connected to the indenter shaft 5, with the rear end of the screw lever 10 connected to the indenter shaft 5 as a reference point, as shown by the solid line in FIG. It's in an upright position.

Reference numeral 14 denotes a handle, which is attached to the frame 1 and formed in a substantially circular arc shape upward relative to the frame 1 in front of the lever 10 so that the longitudinal direction of the lever coincides with the axial direction.

In the present pressure therapy device having the above configuration, when the indenter 3 is pressed in the direction where force is applied by holding the handle 14 with one hand and applying the indenter 3 to an acupuncture point or a stiff place on the human body, the indenter 3 is to achieve the first light pressure in acupressure, and then use the other hand to push the lever 10 in the direction of the arrow P. Starting from the fulcrum pin 11 at the tip, the rear end will push down as shown by the two-dot chain line. Screw lever 10
The lever pin 13 passing through the body is lowered, and the indenter 3 is pushed down as shown by the two-dot chain line, strongly pressing the human body.

When the presser of the screw lever 10 is loosened, the spring 1
The repulsive force of step 2 pushes up the screw pin 13 and returns the indenter 3 and screw lever 10 to their original positions as shown by the solid line, so repeat this push-down operation of the screw lever 10 several times to touch the same location on the human body several times. If you apply strong pressure across the body, you will get the same excellent pressure therapy effect as pressing firmly in acupressure, and you will receive a pleasant stimulation that will make you feel refreshed.

The force pushing the rear end of the screw lever 10 in the direction of the arrow P is proportional to the distance L between the fulcrum pin 11 and the rear end of the screw lever 10 relative to the distance l between the fulcrum pin 11 and the screw pin 13. 5 is amplified, so even if the pressing force of the P arrow is small, the force with which the indenter 3 presses against the human body increases, which can enhance the pressure therapy effect, and the pressing force in the direction of the P arrow increases. Because it is small, fatigue is reduced.

In addition, the reaction force of the force of the indenter 3 pressing against the human body acts in a direction to lift the frame 1, and this is caused by one hand holding the handle 14 and the other hand holding the handle 14
It can be easily caught because it is supported by both hands, including the other hand that pushes down the 0.

In order to see how the indenter 3 hits the human body, part or all of the frame 1 may be made transparent or a peephole may be provided.

Furthermore, in this embodiment, one indenter is illustrated and explained, but there may be two or more indenters, and two or more indenters may be placed in parallel and two or more indenters It is also possible for the indenters to act simultaneously.

(Effects of the device) As explained above, this device uses a simple structure that applies the principle of a lever to obtain a large pressing force with a small force, reduces fatigue, increases medical effects, and provides comfortable pressure therapy for the general public. Not only can anyone perform this at home, but it is also useful in specialized acupressure clinics to reduce labor, and provides a pressure therapy device with excellent practical effects.
