Description

[Detailed Description of the Invention] This invention relates to a pressurized gas distributor operating device for a pine surger that uses pressurized gas.

As a pine surge device using pressurized gas, for example, a pressurized gas generator that supplies pressurized gas,
Some devices include a compression pine surge bag having a plurality of air sacs, and a pressurized gas distributor that appropriately switches and supplies the pressurized gas to the plurality of air sacs via an air supply pipe. In this case, the pressurized gas generator and the pressurized gas distributor are connected by one air supply pipe, and the air supply pipe is connected between the pressurized gas distributor and the compression pine surge bag according to the number of the plurality of air sacs. A plurality of corresponding air supply pipes are connected to supply pressurized gas to the plurality of air sacs in an appropriate manner. Conventionally, the pressurized gas distributor used here has a rotary valve structure, for example. In this method, a valve body having a radial groove is rotatably arranged in the valve casing, and the other end of the air supply pipe connected to the pressurized gas generator is connected to the center of rotation, and the valve body is connected to the groove at all times. At the same time, the other ends of the plurality of air supply pipes connected to each of the air sacs are connected to the groove at a plurality of locations concentric with the rotation center and corresponding to the number of the plurality of air sacs. It has a structure in which the air supply pipe connected to the pressurized gas generator and each air supply pipe connected to the plurality of air sacs can be communicated in a switchable manner by intermittently communicating with each other and rotating the valve body. It is something. At this time, it was common to use an electric motor such as a synchro motor as an actuating device for rotating the rotary valve body of the pressurized gas distribution device.

However, in such a conventional pressurized gas distributor operating device for a pine surger, it is necessary to provide an expensive electric motor to switch the supply of pressurized gas to multiple air sacs, and also to adjust the supply switching speed of pressurized gas. In order to do this, it is necessary to change the voltage or frequency of the power supply, which has the problem of increasing the number of parts and increasing the price.

This idea was made in view of the above-mentioned problems, and allows smooth distribution of pressurized gas without using a drive motor to switch the supply of pressurized gas to a compression pine surge bag having multiple air sacs. conduct,
The purpose of this is to obtain a good pine surge effect.

This invention provides an impeller that is rotated by the flow of pressurized gas supplied from the pressurized gas generator in the middle of an air supply path connecting the pressurized gas generator and the pressurized gas distributor, The present invention is characterized in that the impeller and the rotary valve body of the pressurized gas distributor are connected via a suitable transmission mechanism.

Hereinafter, embodiments of this invention will be described in more detail based on the drawings.

Figures 1 to 4 show one embodiment of this invention, and the illustrated pressurized gas distributor operating device for a pine surger includes a pressurized gas generator 1 that supplies pressurized gas, and a plurality of gas generators that supply pressurized gas. It serves as a driving source for a pressurized gas distributor 5 installed in the middle of an air supply pipe 4 connecting a compressive pine surge bag 2 having a compressor. The distributor 5 and the distributor 5 are housed in the same container 6.

Among these, the pressurized gas generator 1 includes:
Conventionally known belt-type rotary compressors, direct-coupled rotary compressors, diaphragm-type compressors, etc. can be used, but in addition, electromagnetic reciprocating compressors generate pressurized gas by reciprocating a piston by turning on and off an electromagnet. The use of a dynamic type compressor is also preferred in various respects.

Further, as the compression pine surge bag 2 having a plurality of air sacs, for example, the one shown in FIG. 2 is used. That is, a plurality of air sacs 22, 23, 24 and 25 are formed by airtightly joining both materials at the joining line 21 with the stretchable material on the inside and the less stretchable material on the outside; When an air supply pipe 4 is connected to each air supply pipe 4 and pressurized gas is supplied through one of these air supply pipes 4, the inside of the corresponding air sac expands and pine surge pressure is applied. It has a structure. In the case of the illustrated example, the air sacs 22, 23, and 24 are formed into a boot shape as a whole to form the slide fastener 2.
By fixing with the velvet fasteners 27, the air sac 25 is made suitable for applying musculosurge pressure to the lower leg, and by forming the air sac 25 alone and fixing it with a velvet fastener 27, it is suitable for applying musculosurge pressure to the thigh. A plug 28 is attached to the end of each air supply pipe 4 so that a plurality of air supply pipes 4 can be connected instantly. In addition to the illustrated example for feet,
Naturally, there are also pine surge bags for compression of the waist, back, arms, head, etc., but their explanation will be omitted here.

Further, the air supply pipe 4 between the pressurized gas generator 1 and the pressurized gas distributor 5 is provided with an impeller 31 that is rotated by the pressurized gas flow flowing through the air supply pipe 4. A reduction gear train 33 consisting of a large number of gears is connected to the rotating shaft 32 of the impeller 31.
1, the rotation of the rotary shaft 34 is finally rotated at a slow speed and with a large rotational force, and the rotation of the rotary shaft 34 causes the locking member 35 of the pressurized gas distributor 5 and the rotary valve to rotate. The structure is such that the body 53 can be rotated. The locking member 35 and the rotary valve body 5
3 is rotatably disposed within the valve casing 51, and the locking member 35 has a locking protrusion 35a as also shown in FIG. Further, the valve body 53 has a fourth
As shown in the figure, the locking protrusion 53a and the radial groove 5
2. It has an axial exhaust hole 59, etc., and has a structure in which the locking protrusion 35a and the locking protrusion 53a are locked in the rotational direction with some play. moreover,
A compression coil spring 58 is disposed between the locking member 35 and the valve body 53 to constantly press the valve body 53 toward the valve seat 54 to improve airtightness between the valve body 53 and the valve seat 54. There is. A gas passage hole 55 is formed in the valve seat 54 at a position coaxial with the rotation center of the valve body 53 to constantly communicate with the groove 52, and gas passage holes 56 are formed at a plurality of positions concentric with the rotation center. However, a socket 57 is provided so that the tip of the plug 28 can be fitted into the gas passage hole 56. Furthermore, an impeller 31 and a pressurized gas distributor 5
A pressure regulating valve 41 is provided in the air supply pipe 4 between the two. This pressure regulating valve 41 is operated by a compression coil spring 42.
As a result, the valve 43 is pressed against the valve seat 44, and when the pressure inside the air supply pipe 4 exceeds a predetermined pressure, pressurized gas is discharged from the exhaust hole 45 to maintain the predetermined pressure.

Therefore, when using a pine surge device equipped with a pressurized gas distributor operating device having such a structure, the compression pine surge bag 2 is attached to the pine surge site as shown in FIG. 2, and the plug 28 is inserted in the direction of the arrow in FIG. and fit into the socket 57, and then the pressurized gas generator 1 is operated. Then, the pressurized gas is supplied through the air supply pipe 4 into, for example, the air sac 22 of the pine surge bag 2, gradually increasing the pine surge pressure. During this time, the impeller 31 rotates to rotate the valve body 53 at a low speed. Next, when the pine surge pressure reaches a predetermined value, the pressure regulating valve 41 opens and the impeller 31 continues to rotate, so that the groove 52 of the valve body 53 moves away from the gas passage hole 56 shown in the figure and reaches another concentric position (not shown) for gas passage. The air sac 2 communicates with the hole 56.
At the same time as starting the supply of pressurized gas to 3,
The gas passage hole 56 is communicated with the axial exhaust hole 59 provided in the valve body 53, and the pressurized gas inside the air sac 22 is discharged. , 23, 24 and 25, pressurized gas is sequentially supplied and discharged. At this time, by adjusting the flow rate of the pressurized gas supplied from the pressurized gas generator 1, each air pouch 22, 23, 2
4 and 25 can be changed, and by adjusting the operating pressure of the pressure regulating valve 41, the maximum pine surge pressure can be changed.

As described above, in this invention, the rotary valve body of the pressurized gas distributor is rotated using the rotational force of the impeller rotated by the flow of pressurized gas as a driving source, and pressurized gas is distributed to multiple air sacs. This eliminates the need to use an expensive drive motor to operate the pressurized gas distributor as in conventional systems, and the flow of pressurized gas can be directly used to switch the pressurized gas supply. By using it as a driving source,
This has an extremely excellent effect in that the supply of pressurized gas to the compression pine surge bag can be smoothly switched, thereby obtaining a good pine surge effect.
