Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a traction treatment device that is most suitable for being incorporated into a roller treatment machine that administers a desired treatment to a human body while lying down.

This type of device has never existed before, and the following may be the reason for this.

That is, the roller therapy machine itself does not have a space for installing other equipment, and the conventionally known traction therapy device is too large, making it impossible to integrate the two.

Furthermore, the human body must be towed while lying on the roller treatment machine, but in this case, the position of the human body on the treatment machine is almost fixed.

Since a predetermined traction must be performed from a predetermined position, it is difficult to set the length of the wire that transmits the traction force, for example.

For the above-mentioned reasons, no roller therapy machine has ever been equipped with a traction device.

This invention reduces the size of the traction treatment device, and
The purpose is to provide a device that allows the length of the wire to be easily set.

Embodiments of the present invention will be described below with reference to the drawings.

The roller treatment machine a shown in FIGS. 1 and 2 has a movable frame 2 mounted on a main body 1 so as to be able to reciprocate in its longitudinal direction.

As is clear from FIG. 2, the main body 1 is provided with a plurality of rollers 3 to 7 of different types.

Among them, the roller 3 always projects upwardly from the window hole 8, and the other rollers 4 to 7 can be projected from or retracted from the window hole 9 by a hydraulic drive mechanism.

The movable frame 2 is covered with canvas or the like, on which a person lies.

If a desired roller is made to protrude from the window hole 9 while moving the movable frame 2, the human body is pressed by the roller and the desired therapeutic effect is exerted.

The traction treatment device of the present invention is incorporated into this roller treatment machine as follows.

That is, on one side of the moving frame 2, a pair of shoulder bands 10,
11, and the shoulders are fixed with these bands 10 and 11 as shown in FIG.

Then, a connecting fitting 13 is attached to another band 12 that is directly fixed to the waist of the human body, and the traction wire 1 is attached to this connecting fitting 13.
Hook 4.

The wire 14 hooked on the connecting fitting 13 as described above is guided into the main body 1 through the guide member 15, but the guide member 15 is removable from the plate 16.

That is, the guide member 15 has the support member 1 at its lower end.
7 is fixed.

This support member 17 maintains a length that crosses the plate 16, and, as is clear from FIG. 3, has U-shaped portions 18 at both ends.

By fitting the U-shaped portions 18 onto both sides of the plate 16 and sliding the support member 17 until it comes into contact with the stopper 19, the guide member 15 is stopped at the position shown in FIG.

Furthermore, when moving the movable frame 2 to perform roller treatment, the guide member 15 can be removed by pulling out the support member 17 from the plate 16, so that movement of the movable frame 2 is not hindered.

On the other hand, a support member 20 is provided inside the main body 1, and a pair of guide rods 21 and 22 are provided behind the support member 20.

Brackets 2 are placed on both sides of the cylinder 23 at required locations.
A guide rod 2L22 is configured to penetrate through these rackets, so that the cylinder 23 can move along the guide rod.

Also, between the front and rear brackets, stoppers 28 and 29 fixed to the support member 20 are provided, and springs 30 and 31 that generate a traction force between these stoppers 28 and 29 and the rear flakets 25 and 27 are provided. is interposed.

The piston rod 32 of the cylinder 23 as described above is provided with a pulley 33 at its tip.

Then, the pulling wire 14 guided into the main body 1 is routed around the pulley 33, and one end of the wire is connected to the winding wheel 33.
I've stopped it at 4.

A spring force is always applied to the winding ring 34 in the direction of winding the traction wire 14.

A ratchet gear 35 is provided on this winding ring 34,
The ratchet gear 35 and the rotation preventing means 36 allow the winding ring 34 to be stopped at a desired rotational position.The structure of the rotation preventing means 36 is as follows.

That is, as is clear from FIG. 5, the rotation prevention stage 36 is composed of a solenoid 37 and a pawl member 38, and when the solenoid 37 is energized, the pawl member 38 hits the ratchet gear 35, and the winding ring 34 The relationship is such that it inhibits the rotation of

The solenoid 36 is configured to be energized when a drive switch (not shown) of the traction device is turned on.

Under the above configuration, if the solenoid 36 is in a de-energized state, the pawl member 38 retreats from the ratchet gear 35, the winding ring 34 rotates in the direction to wind up the wire 14, and the wire This will eliminate the slack in 14.

If one end of the wire 14 is pulled from the above state, the winding ring 34 rotates against the spring force, so that the wire can be pulled out.

If the end of the wire pulled out in this way is hooked on the connecting fitting 13 fixed to the human body, the wire will always be in a tense state at the hooked position.

In other words, the wire can always be maintained at an optimal length, regardless of the height of the person lying on the roller treatment machine.

When using the traction treatment device, the guide member 15 is first set on the plate 16.

Then, the traction wire 14 wound around the winding ring 34 is pulled out and hooked onto the connecting fitting 13 fixed to the human body.

When the drive switch is turned on after doing this, the winding wheel 34 is stopped at a predetermined position by the pawl member 38, and at the same time, each control valve shown in FIG. 7 is switched as follows.

That is, the pair of control valves 39 and 40 are switched to the right position, and at the same time, the safety valve 41 is set to the upper position.

When the directional control valve 42 is switched to the right position in this state, the cylinder 23 contracts and moves against the springs 30 and 31.

In other words, the repulsive force of the springs 30 and 310 acts as a force that pulls the human body.

Therefore, the traction force is determined by the amount of deflection of the springs 30 and 31, but the traction force can also be adjusted using a magnetic proximity switch (not shown) that detects this amount of deflection.

In this case, you can choose the traction force in advance depending on your lover.

Furthermore, as described above, the traction wire 14 is passed through the pulley 33 and fixed to the take-up ring 34, so the cylinder 23
The amount of tension is doubled for the moving stroke of .

In other words, the movement stroke of the cylinder can be made smaller and the size can be reduced accordingly.

Furthermore, for the same reason, half of the combined force of the two springs 30, 310 acts as a traction force, so in principle it is only necessary to consider the amount of deflection of one spring.

Traction treatment is performed as described above, but if electricity is interrupted for some reason such as a power outage during the treatment, the sonoid 37 becomes de-energized and the pawl member 38 disengages from the ratchet gear 35, and at the same time the safety valve 41 returns to the illustrated state to short-circuit the respective ports of the cylinder 23.

In other words, the patient is freed from traction forces.

Note that the reference numeral 43 in the figure is a relief valve.

Further, when finishing the traction treatment, if the directional control valve 42 is switched to the left position, the cylinder 23 is extended and returned to its original position, and the traction force becomes O.

Note that the reference numeral 44 in the figure is a cylinder for vertically moving any one of the rollers 4 to 7 described above.

As is clear from the above description, according to the traction treatment device of the present invention, the cylinder is mounted on the guide rod installed on the support member, and the guide rod is mounted on the guide rod by moving relative to the cylinder. Since a spring is provided that bends and generates a predetermined traction force, the traction force generation mechanism can be downsized.

In other words, since the cylinder and spring can be integrated into the support member, the installation space can be extremely reduced, and this traction mechanism can therefore be incorporated into a roller treatment machine.

In addition, the wire is passed around the pulley installed in the above cylinder,
One end of the wire is wound around a winding ring, and the other end is connected to a traction part of the human body, and a force is applied to the winding ring in the direction of constantly winding the traction wire, and when the cylinder is being driven. By providing rotation blocking means to prevent its rotation, the wire is always maintained at its optimum length when its end is connected to the human body.

Therefore, even if the height of the person lying on the roller treatment machine is different, the wire will not become slack or the wire will not be long enough.
