Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an acupressure device that performs massage on the body by reciprocating a massage roller.

[Technical background of the invention and its problems]

In general, this type of acupressure device has a movable holder holding a pine surge roller inside a base with an open top and an exterior covering stretched over the opening, and the holder is moved back and forth by a drive source. By running the vehicle, the user lying supine on the exterior ground is pine-surged by the pine-surge roller.

By the way, the pine surge effect produced by the pine surge roller loosens stiffness in the muscles of the human body, improves blood circulation, and relieves fatigue. Therefore, if the pine surge is performed using the pine surge roller while warming the human body, the pine surge effect can be further enhanced.

Therefore, the applicant proposed the acupressure device shown in the specification and drawings of Utility Model Application No. 174086/1986. In other words, in this prior art, a heat dissipation plate made of a plate material with relatively high thermal conductivity such as aluminum is provided in the base of the acupressure device, a heating element made of a positive temperature coefficient thermistor is attached to this heat dissipation plate, and the heating element is The heat is used to warm the user. however,
In an acupressure device that pine-surges a user by running a pine-surge roller, a space for the pine-surge roller to run must be secured on the lower surface of the exterior area where the user lies on his or her back. Therefore, most of the heat radiated from the heating element consisting of a positive temperature coefficient thermistor ends up heating the air layer in the space and the main body, and does not work effectively to warm the user lying supine on the exterior surface. There was a case of leprosy. In addition, when a user lies on the exterior ground, the body is warmed by the heat transmitted from the exterior fabric when the heating element warms the exterior fabric, so it is easy to warm only the surface of the body and it is difficult to warm the core. Therefore, it is not possible to effectively receive pine surgery while the body is sufficiently warmed.

[Purpose of the invention]

An object of the present invention is to provide an acupressure device that enables a user lying supine on the exterior ground to receive pine surge efficiently and well while warming the user from the core of the body.

[Summary of the invention]

This invention provides a far-infrared heater in a portion of a base body provided with a holder that holds a pine surge roller and is reciprocally driven and corresponds to the range in which the holder travels, and also provides a far-infrared heater on a surface of the base body where the holder is provided. This is an acupressure device formed by covering the above-mentioned holder with an exterior material.

It consists of 0,152. And the belt 86
When the plate-shaped body 12 travels a predetermined distance in one direction,
6, the first limit switch 150 is activated to switch the running direction to the opposite direction, and when the vehicle has traveled a predetermined distance in that direction, the second limit switch 152 is activated and the running direction is switched. This is happening repeatedly.

In addition, as will be described later, a portion of the upper surface of the base body 2 corresponding to the range in which the pair of holding bodies 90 travel, a portion corresponding to the waist of the user when the user lies supine on the base body 2, in this embodiment. As shown in FIG. 1, a far-infrared heater 154 is provided at one of the first flexible portions 8. As shown in FIG. As shown in FIGS. 14 and 15, this far-infrared heater 154 is provided with a similarly flexible electric heater 156 between a pair of flexible synthetic resin sheets 155 joined together, and an upper synthetic resin sheet. Ceramics 157 are provided in a layered manner on the upper surface of 155 by appropriate means, such as adhesion or plating with metal foil.
Therefore, when the electric heater 155 is electrically heated, far infrared rays having a wavelength of 4 to 50 μm are output.

Furthermore, as shown in FIG. 1, a wall member 160 is provided on the upper surface of the base 2 on the outside of the pair of guide rails 10 and at one longitudinal end of the base 2. This wall member 160 is made of a bendable elastic material, such as urethane foam. Furthermore, the base body 2 is made of an exterior fabric 162 made of a material that has relatively excellent abrasion resistance and is difficult to absorb the far infrared rays outputted from the far infrared heater 154, such as nylon, and is sewn into a bag shape. covered. By lying down on this exterior fabric 160, the user can receive pine surge from the pine surge roller 118 provided on the holder 90.

Next, a case where the pine surgery device 1 having the above structure is used will be explained. First, when the user lies face up on the massage device 1, the user operates a switch box (not shown) to activate the drive source 64 of the drive device 56 and energize the far-infrared heater 154. If the drive source 64 operates,
Since the pair of belts 86 are driven to run, the holder 90 is interlocked with this running, and the pine surge roller 118 provided on the hollow shaft 92 of the holder 90 is rotated by contact resistance with the inner surface of the exterior material 162. The user runs while moving, and the protrusion 120 hits the back of the user.

On the other hand, the energized far-infrared heater 154 outputs far-infrared rays with a wavelength of 4 to 50 μm. This far-infrared rays have a straight propagation property and can easily pass through the exterior material 162 where the user is lying on his/her back, so the user is irradiated without much loss. Far infrared rays are easily absorbed by the human body, and 40%
It can penetrate up to ~50mm, so it warms the human body from the inside. In other words, the user can receive the pine surge while keeping his or her body well warmed from within, which can improve the pine surge effect.

Further, since the far-infrared heater 154 is made of a flexible synthetic resin sheet 155, it can be bent. Therefore, the far-infrared heater 155 provided at the first flexible portion 8 of the base body 2 is
When the base body 2 is folded as shown in FIG. 16 for storage when not in use, it is freely bent together with the base body 2, so there is no resistance or damage during folding.

Note that this invention is not limited to the above embodiment,
For example, if the base is made of a material that easily transmits the far-infrared heater, the far-infrared heater may be provided on the bottom surface of the base instead of on the top surface.

Furthermore, the exterior covering may be provided in a state that only covers the upper surface side of the base.

Furthermore, shiatsu devices are not limited to bed type devices.
It may be of a chair type.

〔Effect of the invention〕

As described above, the present invention has a far infrared heater disposed on a base body provided with a holder that holds a pine surge roller and is driven back and forth, and a user who is lying on his back on the exterior ground covering the holder, It is now possible to receive pine surge while warming the body with far infrared rays output from the heater. Therefore, even if there is a space for the above-mentioned holder to run between the user who is lying on the exterior surface and the far-infrared heater, the far-infrared rays can efficiently warm the user without heating the above-mentioned space. Moreover, since the user's body is warmed from the core, not only can the pine surge effect by the pine surge roller described above be sufficiently enhanced, but even a far-infrared heater with a small capacity can warm the user well. Also, the base is folded from the flexible part when not in use.
At that time, the infrared heater made of flexible material can be folded together with the base.
There is no possibility that the far-infrared heater provided on the upper surface of the base body becomes an obstacle that prevents the base body from being folded.
