Description

Detailed Description of the Invention

[0001]

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 this type of infrared treatment device, two infrared irradiators are provided. For example, when the site that irradiates infrared rays is both shoulders and feet, the two infrared irradiators are used apart from each other. When the region to be irradiated with is the waist, it is conceivable to use two infrared irradiating bodies close to each other (see Japanese Utility Model Laid-Open No. 2-45760).

[0003]

However, since the infrared irradiation amount per unit area changes depending on whether the two infrared irradiation bodies are used apart from each other or used close to each other, whichever infrared irradiation amount is used. It is difficult to secure the form. Also, even if the user adjusts the infrared irradiation amount by adjusting the knob by himself, it is troublesome for the user to adjust the infrared therapy device for each usage mode, so the adjustment is eventually made. It is thought that it is often used without being processed.

In view of the above circumstances, the present invention provides an infrared therapeutic device capable of automatically obtaining an appropriate infrared irradiation amount both when two infrared irradiating bodies are used apart from each other and when they are used close to each other. The purpose is to do.

[0005]

The infrared therapeutic device of the present invention is an infrared therapeutic device in which the arrangement intervals of the two infrared irradiating bodies can be adjusted, and detection is performed to detect the arrangement intervals of the infrared irradiating bodies. Means and an energization amount control means for increasing the energization amount to the infrared irradiating body when the arrangement interval is widened and decreasing the energization amount to the infrared irradiating body when the arrangement interval is narrowed. Characterize.

Here, the term "adjustment of the arrangement interval of the infrared irradiators" means that, for example, two infrared irradiators are rotatably provided, and the arrangement interval is adjusted by the amount of rotation, or the two infrared irradiators are parallel. It is provided so as to be movable, and the arrangement interval is adjusted by the parallel movement amount. Further, as the detecting means for detecting the arrangement interval of the infrared irradiators, a volume or the like provided so that the resistance value changes depending on the rotation amount or the parallel movement amount can be used.

An infrared therapeutic device equipped with such means is
When the arrangement interval of the infrared irradiating body is widened, the energization amount to the infrared irradiating body is large, and when the arranging interval is narrow, the energizing amount to the infrared irradiating body is small. It is possible to secure a sufficient infrared irradiation amount. In addition, the user does not need to make adjustments for each type of use, which is convenient.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of an infrared therapeutic device of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the appearance of a stand-type infrared therapeutic device 1. A switch / timer 18 is provided on the base 2 of the infrared treatment device 1. The timer 18 can be used to adjust the power ON and power ON time.

A column 3 is erected on the base 2.
A flexible pipe 4 is provided on the column 3. A heat unit 5 is attached to the upper end of the flexible pipe 4.

As shown in FIGS. 2 and 3, the heat unit 5 comprises a first unit portion 5a and a second unit portion 5b. First unit portion 5a and second unit portion 5b
Are fitted to the support shaft 8 and are provided so as to be rotatable around the support shaft 8. The support shaft 8 is connected and fixed to the flexible pipe 4. An infrared lamp 6 as an infrared irradiator is attached to each unit 5a, 5b.

FIG. 4 is a vertical sectional side view of the heat unit 5. A first gear 9 is fitted to a portion of the support shaft 8 located inside the second unit portion 5b. A volume (variable resistor) 10 is fixed at a position near the support shaft 8 in the second unit portion 5b. A second gear 12 is fitted on the rotary shaft 10 a of the volume 10. And, this second gear 12
It is meshed with the first gear 9. In addition, the volume 10 includes a control circuit (energization amount control means) 15 described later.
It is connected to the.

FIG. 5 is a circuit diagram showing the control circuit 15. The control circuit 15 inputs the alternating current supplied from the alternating current power source 16 and performs phase control based on the resistance value of the volume 10, and the infrared lamps 6, 6 of the first unit section 5a and the second unit section 5b, respectively. The energization amount of 6 is controlled. More specifically, when the distance between the first unit portion 5a and the second unit portion 5b becomes wide, the energization amount to the infrared lamps 6 and 6 is increased so that the first unit portion 5a and the second unit portion 5b are separated from each other. When the interval becomes narrow, control is performed so that the amount of electricity supplied to the infrared lamps 6 and 6 is reduced. The control method in the control circuit 15 is not limited to the above phase control.

Next, the operation of this infrared therapeutic device will be described. When the first unit 5a or the second unit 5b is rotated, the second gear 12 meshed with the first gear 9 rotates, and the rotation of the second gear 12 causes the volume 1 to rotate.
The rotation axis of 0 rotates, and the resistance value of the volume 10 changes. Then, phase control is performed in the control circuit 15 based on the change in the resistance value of the volume 10, and as shown in FIG. 3, the first unit portion 5a and the second unit portion 5b.
When the distance between the infrared lamps 6 and 6 is widened, the amount of electricity to the infrared lamps 6 is increased, and as shown in FIG. 2, when the distance between the first unit portion 5a and the second unit portion 5b is narrowed, the infrared lamps The amount of electricity supplied to 6, 6 is reduced. Therefore, it is possible to secure an appropriate amount of infrared radiation in either usage pattern. Moreover, it is not necessary for the user to make adjustments for each type of use, which improves usability.

In the above embodiment, as an example in which the arrangement interval of the two heat lamps 6 and 6 can be adjusted, the first
Although the example in which the second unit portion 5b is rotatably supported by the support shaft 8 around the horizontal axis has been shown in the unit portion 5a, the present invention is not limited to this, and the second unit portion 5b may be rotatably supported around the vertical axis. Good. In addition to the rotation, the first unit portion 5a
And the second unit portion 5b may be provided so as to be movable in parallel. In this case, instead of the volume 10, a slide resistance may be provided, or a pinion may be fitted to the rotary shaft of the volume 10 and a rack that moves by the parallel movement may be provided.

Considering that the use form in which the two heat lamps 6 and 6 are separated from each other is the use form for the treatment of irradiating both shoulders with infrared rays, the first use suitable for the treatment of both shoulders. An infrared therapeutic device that considers only two modes, that is, a form and a second use form (for example, for lumbar treatment) in which the heat lamps 6 and 6 are brought close to each other, is also conceivable. In such an infrared treatment device, two-step energization amount control according to the amount of rotation of the second unit portion 5b is performed instead of analog-type energization amount control according to the amount of rotation of the second unit portion 5b. It is possible.

When performing the two-step energization amount control, for example, instead of the volume 10, a switch for performing a switching operation with a certain amount of rotation is provided. By selecting one of the two resistors having different resistance values by the selection operation of the switch, the amount of electricity to the heat lamps 6, 6 is increased in the first usage pattern, In the second usage mode, it is possible to control the heat lamps 6 and 6 so as to reduce the amount of electricity supplied to them.

Further, the turning range of the turning shaft of the volume 10 is narrower than the turning range of the unit portions 5a and 5b, and the second gear 12 mounted on the turning shaft slips at a certain torque or more. If configured so as to occur, energization control according to the amount of rotation of the rotation shaft 10a of the volume 10 is performed from the state where the two unit parts 5a and 5b are in contact with the state where they are separated to some extent, while Unit 5a,
It is also possible to perform control such that the slip occurs and the amount of electricity to the heat lamp 6 does not change when 5b is further apart (for example, in a range suitable for treating both shoulders).

[0019]

As described above, according to the present invention, an appropriate amount of infrared irradiation is obtained in both the use mode in which the arrangement interval of the infrared irradiating body is widened and the use mode in which the arrangement interval is narrowed. Can be secured. In addition, since it is not necessary for the user to make adjustments for each usage mode, the user-friendliness is also achieved.
