BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an infrared therapeutic device used for treating stiff shoulders and the like.

[0002]

2. Description of the Related Art Conventionally, infrared rays (including far-infrared rays) emitted from an infrared irradiator such as an infrared lamp or ceramic are applied to an affected area, and the deep area is appropriately warmed without excessively heating the skin of the affected area for treatment. Infrared therapeutic devices are known that are effective. In addition, in this type of infrared treatment device, a heat unit with a built-in infrared irradiator is installed on the support column to support the infrared irradiator so that the height and direction of the infrared irradiator can be changed as desired. It is rotatably provided and the posture of the heat unit is held by tightening a screw with a pair of knobs, or the column portion is rotatably provided on the base to maintain the posture of the column portion. It has been proposed to perform screwing by using a pair of knobs (see Japanese Utility Model Laid-Open No. 61-148351 and Japanese Utility Model Laid-Open No. 3-104359, IP.
C: A61N5 / 06).

[0003]

However, in the above-mentioned conventional infrared therapy device, it is necessary to turn both the pair of knobs to perform screw tightening, so that the operation of adjusting the angle of the heat unit is troublesome. In addition, since the heat unit becomes hot during use, it is necessary to provide a handle on the heat unit in order to adjust the angle of the heat unit during use, but this has the disadvantage of increasing the number of parts. is there.

In view of the above circumstances, the present invention provides an infrared therapeutic device which can easily adjust the tilt of a heat unit or a column, and can adjust the tilt of the heat unit without providing a handle. To aim.

[0005]

An infrared therapeutic device according to the present invention comprises a heat unit containing an infrared irradiator, a support for supporting the heat unit, and a side of the heat unit connected to the support. Then, in an infrared therapeutic device provided with a pair of coupling devices with knobs for rotatably supporting the heat unit about a horizontal axis, one coupling device with knob rotates the heat unit by rotating the knob. In addition to being movable, it is possible to prevent rotation of the heat unit due to its own weight and to allow rotation by turning the knob by pressing force of an elastic body interposed between the support unit and the column. The other coupling device with a knob is configured such that the heat unit can be fixed by turning the knob.

Here, when adjusting the direction of the heat unit, the knob of the coupling device with the other knob is loosened to form a state in which the rotation of the heating unit is allowed, and the knob of the coupling device with one knob is turned. As a result, the heat unit is rotated to adjust the infrared irradiation direction. Then, after this direction adjustment, the knob in the other coupling device is tightened. That is, the direction of the heating unit can be adjusted without touching the heating unit by operating the knob of one coupling device, and the heating unit can be fixed by operating the knob of the other coupling device.

Further, in adjusting the direction of the heat unit, even when the knob of the other connecting device is loosened, the pressing force of the elastic body in the one connecting device does not cause the heat unit to rotate under its own weight. At that time, the heat unit does not rotate unexpectedly and touch the user's hand.

Further, the infrared treatment device of the present invention comprises a heat unit containing an infrared irradiator, a support portion for supporting the heat unit, and a rotation joint for rotatably supporting the support portion. In the infrared treatment device, knobs are provided on both sides of the rotary joint, and the knob is provided in a screwed-in completed state on the side of the rotary joint where the one knob is provided, and the pivot portion rotates. It is characterized in that it is configured so as to impart a resistance force to the column, and on the side where the other knob is provided, the pillar portion can be fixed by turning the knob.

As described above, on the side where the one knob is provided, since the knob is completely screwed in, there is no involvement in the rotation and fixing of the column, and the rotation and fixing of the column is not performed. Since the operation is performed only by operating the other knob, the operation becomes easy. In addition, since the one knob is configured to give a resistance force to the rotation of the support column, the support column is rotated by its own weight even when the other knob is loosened. It is possible to maintain the posture of the support column without causing any trouble. Further, even when a spring is used to maintain the posture of the support column, the rotation resistance force on the side on which the one knob is provided functions to supplement the elastic force of the spring, so that the spring is comparatively used. It becomes possible to use one having a weak elastic force.

It is arranged around this so as not to interfere with, and reaches the inside of the cover 12 (inside the heat unit 5) through the holes of the guide portions 44a and 45a.

A coil spring 46 is provided on the outer side of the spacer 41 between the back knob base 45 and the tip of the arc of the upper column 3a. One end of the spiral spring 46 is locked and fixed to the tip of the arc portion.

Here, the knob 42 is turned to turn the screw 4
When 2a is tightened into the nut 43, the screw portion 42
The screw portion 42a and the nut 43 are fixed at a position where the head portion of a and the nut 43 hit the end surface of the spacer 41 (note that the nut 43 and the screw portion 4 are made by using Loctite).
2a may be strengthened), and in this fixed state, the knob 42, the screw portion 42a, the nut 43, the front knob base 44, the back knob base 45, and the cover 12 (heat unit 5) are integrated, and the whole of them. It can be rotated around the hole 31 at the tip of the arc portion.

That is, if the knob 42 of the one connecting device 4 is turned, the heating unit 5 is turned. In addition, the rotation of the heat unit 5 is performed by the winding spring 46 that is compacted between the tip of the circular arc portion of the upper column portion 3b that is a non-rotating portion and the back knob base 45 that is a rotating portion. Resistance is given to. This resistance force is set so as to prevent the heat unit 5 from rotating due to its own weight, but to allow the user to rotate due to the operating force.

On the other hand, the other connecting device 4 shown in FIG. 2 (b) also has substantially the same structure as described above, but has a structure for passing the power cord 15 inside the cover 12. They are different in that they are not provided and that the spacer 41 and the winding spring 46 are not provided. Due to this latter difference, when the screw portion 42a is tightened into the nut 43, the knob 42, the screw portion 42a, the nut 43, the front knob base 44,
Not only the back knob base 45 and the cover 12 (heat unit 5) but also these and the upper support portion 3b are integrated, so that the rotation of the heat unit 5 is prevented.
That is, by rotating the knob 42 and tightening the screw 42a in the other coupling device 4, it is possible to prevent the heat unit 5 from rotating even when the operating force of the user is applied.

FIG. 3 is a sectional view showing the internal structure of the rotary joint 6 in detail. The rotation joint 6 includes a fixed support portion 61 fixed to the lower support column 3a, a rotation support portion 62 that rotatably supports the upper support column 3b, and a cover portion 63.

A pair of fitting portions 61a, 61a are formed under the fixed support portion 61, and these fitting portions 61a, 61a are formed.
a is fitted to the upper ends of the two pipe members forming the lower strut portion 3a, and is fixed to the lower strut portion 3a. A first standing portion 61c that rises upward outside the pipe members is provided on the fitting portions 61a, 61a.
And the second standing portion 6 that rises upward inside the pipe member.
1d is formed. The pipe support portion 62, which is a part of the rotation support portion 62, is formed by the upright portions 61c and 61d.
An accommodating portion 61e for accommodating a is formed.

Further, a stopper portion 61f is formed in the accommodating portion 61e so as to regulate the turning range of the turning support portion 62. Further, a through hole 61g penetrating in the lateral direction is formed in the first standing portion 61c.

The rotation support part 62 is a pair of pipe support parts 6.
2a and 62a, and a shaft portion 62b that connects and fixes these pipe support portions 62a and 62a. Pipe support 62
The reference character “a” is composed of a flat cylindrical rotating portion housed in the housing portion 61e, and a fitting portion projecting upward from the housing portion 61e and into which the pipe member of the upper support portion 3b is fitted.

A cylindrical portion 62d and a through hole 62c having a center on the central axis of the cylindrical portion 62d are formed in the rotating portion of the pipe supporting portion 62a. The through hole 62c
Is located on the same axis as the through hole 61g of the first standing portion 61c. In addition, in the cylindrical portion 62d, as shown in FIG.
As shown in (b), the winding spring 9 is fitted on the outside.
One end side 9a of the spiral spring 9 is provided so as to enter into each pipe member forming the upper strut portion 3b through a hole formed in the bottom portion of the pipe support portion 62a, and the other end side 9b.
Is fixed.

Since the winding spring 9 is provided, as shown in FIG. 4 (a), when the upper strut 3b is rotated, the load of the heat unit 5 is opposed by an elastic force, and the heat is not applied. It is possible to prevent the unit 5 from freely rotating due to its own weight and maintain the tilted posture, and the user can change the tilted posture by operating the upper support column 3b against the elastic force of the coil spring 9. .

Knobs 8 (hereinafter, the left knob is referred to as one knob and the right knob is referred to as the other knob) are provided on both sides of the rotary joint 6, respectively. Each knob 8
Is provided with a screw portion 8a, and this screw portion 8a is
It is inserted into a cylindrical spacer 64 provided through the through hole 61g and the through hole 62c. The tip portion of the screw portion 8a reaches the inside of the shaft portion 62b and is screwed into a nut 8b provided in the shaft portion 62b.

Here, as can be seen from FIG. 3, a spacer 64 is provided between the left side constituent portion (the side on which the one knob 8 is provided) and the right side constituent portion (the side on which the other knob 8 is provided) of the rotary joint 6. There is a difference in length.

In the left component of the rotary joint 6, the spacer 64 has a length flush with the inner end surface of the through hole 62c (the surface with which the nut 8b abuts). Therefore, when the screw portion 8a is tightened into the nut 8b, the knob 8 does not rotate any more at the position where the head of the screw portion 8a and the nut 8b hit the spacer 64 (screwed completed state). become. Then, in this screwed-in completed state, between the side surface of the rotating portion of the pipe support portion 62a of the rotating support portion 62 and the side surface of the first upright portion 61c of the fixed support portion 61 from the lateral direction. An appropriate surface pressure is generated by the pressing, and an appropriate resistance force is applied to the rotation of the upper support column 3b.

On the other hand, in the right side constituent portion of the rotary joint 6, the spacer 64 does not reach the inner end surface of the through hole 62c. Therefore, when the knob 8 is turned to screw the screw portion 8a into the nut 8b, the side surface of the rotating portion of the pipe supporting portion 62a in the rotating supporting portion 62 and the first upright position of the fixed supporting portion 61. The side surface of the portion 61c is strongly pressed by the amount of the screwed-in portion, so that the rotation support portion 62 can be prevented from rotating. Of course, if the knob 8 is turned in the opposite direction, the rotation support portion 62
Can be allowed to rotate.

As described above, on the side where the one knob 8 is provided (the left side constituent portion), since the knob 8 is completely screwed, it does not participate in the rotation and fixing of the upper support column 3b. The rotation and fixing of the upper support column 3b can be performed only by operating the other knob 8, which simplifies the operation. Also,
Since the one knob 8 is configured to give a resistance force to the rotation of the upper strut portion 3b, even when the other knob 8 is loosened, the upper strut portion 3b is automatically operated by its own weight of the heat unit 5. It does not rotate to the upper column 3b
It is possible to maintain the posture. Further, even when the winding springs 9 and 9 are used to hold the posture of the upper support column 3b, the rotation resistance force on the side where the one knob 8 is provided (the right component) is the winding springs 9 and 9. Since it functions so as to supplement the elastic force of, the coil springs 9, 9 having relatively weak elastic force can be used.

A spring washer or the like may be provided on the pressing surface side of the nut 8b on the side where the one knob 8 is provided (the left side constituent portion) in order to impart a resistance force to the rotation of the upper support column 3b. It is conceivable that, however, it is impossible to simultaneously satisfy the condition that the knob 8 does not rotate any more (screw-in completed condition) and the application of the appropriate resistance force. Further, on the side where the other knob 8 is provided (on the right side), the spacer 64 may not be necessary, but the rotation support portion 62 can be smoothly rotated.
Further, it can be said that it is desirable to provide the spacer 64 from the viewpoint of preventing the settling of the shaft portion and the bearing portion due to the repeated rotation.

When the rotary joint 6 is made of resin, when the screw portion 8a is tightened by the nut 8b, the through hole 62c is likely to be deformed. Therefore, in this embodiment, the nut 8b
A washer 50 is provided between the and the portion where the through hole 62c is formed to prevent the above deformation. Further, when the cover portion 63 of the rotary joint 6 is attached, the cover portion 6 located above the first standing portion 61c is attached.
3 and the pipe support 6 in the rotary joint 6
Although there may be a gap between the rotary portion of 2a and the rotating portion, the portion of the cover portion 63 located above the first upright portion 61c can be pressed by the knob 8. A gap is prevented from occurring.

By the way, the rotary joint 6 shown in FIG.
In addition, although the fixed support portion 61 is provided with a stopper 61f, the stopper 61f is useful in restricting the rotation of the upper support column 3b when the infrared therapeutic device 1 is used.
When the infrared therapeutic device 1 is to be stored, it is impossible to fold the upper support portion 3b by largely rotating it because of the stopper 61f.

FIGS. 5 (a) and 5 (b) are views showing a rotary joint 60 and a knob 80 that can be folded by greatly rotating the upper support portion 3b during storage. In this drawing, the same functional parts as those of the rotary joint 6 are designated by the same reference numerals. The knob 80 shown in FIG. 5 has a stopper 80a for restricting the rotation of the upper support column 3b. The stopper 80a is formed in a rod shape, and has a length such that when the knob 80 is attached to the side of the rotary joint 60, the stopper 80a passes through the accommodation portion 61e of the fixed support portion 61 and reaches the second standing portion 61d. It is set. The first upright portion 61c is formed with a hole 83 into which the rod-shaped stopper 80a is inserted.

Further, since the stopper 80a is provided, a threaded portion is formed on the knob 80, and the rotary joint 6 is provided.
Since the knob 80 cannot be mounted by screwing it in, the knob 80 is formed with a shaft portion 80a and a male side engaging portion 80b instead of the screw portion, and the first standing portion 61c is provided with a female side engaging portion 61h. Is formed, and the knob 80 can be mounted by pushing the knob 80 toward the rotary joint 6.

In the structure of FIG. 5, the stopper 80a is provided when the knob 80 is attached to the rotary joint 60.
As a result, the rotation range of the upper support column 3b can be regulated as shown in FIG. 7A, while the knob 80 is disengaged from the rotation joint 60 as shown in FIGS. 6A and 6B. Then, since the stopper 80a is detached from the storage portion 61e, as shown in FIG. 7 (b), the upper support portion 3b can be largely rotated, and the storage can be made compact.

[0041]

According to the invention described in claim 1, the direction of the heat unit can be adjusted by operating the knob of one of the coupling devices without touching the heat unit, and the posture of the heat unit can be maintained. Since it can be performed only by operating the knob of the other coupling device, the usability is improved. Furthermore,
Even when the knob of the other coupling device is loosened, the heating unit does not rotate under its own weight due to the pressing force of the elastic body in the one coupling device, so that the heating unit unexpectedly rotates and falls into the user's hand. No more touching.

According to the invention described in claim 2,
Since the rotation and the fixing of the column can be performed only by operating the other knob, the usability is improved. Further, even when the other knob is loosened, it is possible to prevent the column part from freely rotating due to its own weight, and even when a spring is used to maintain the posture of the column part, Since the dynamic resistance force functions to supplement the elastic force of the spring, it is possible to use a spring having a relatively weak elastic force as the spring.
