Description

[Detailed Description of the Invention] [Prior Art Field] This invention relates to an acupressure device that applies acupressure to a user using a pine surge roller that is driven to travel.

[Technical background of the invention and its problems]

Generally, the above-mentioned acupressure device has a pair of guide rails laid along the longitudinal direction on the upper surface of the base, and a holder to which a pine surge roller is attached is movably provided along the guide rails. Further, a driving source is disposed at one end in the longitudinal direction of the base, and the holding body is driven to travel by this driving source.

By the way, in the acupressure device having such a structure, in order to enable the pine surgery roller to perform pine surgery on the user's entire body, the base body must be made longer than the user's height. That is, the substrate must be approximately 2 meters long or more. As a result, the pine surge device is quite large, which is a nuisance when not in use, and it is difficult to find a place to store it when it is stored.

In order to eliminate these drawbacks, the present applicant proposed an acupressure device as shown in Japanese Patent Application No. 185132/1982. That is, in this prior art, the base and the guide rail can be bent, and the length can be reduced by folding the base and the guide rail when not in use.
However, in such acupressure devices, the base body may be bent more than necessary, or the base body may be folded because the user forgets to stop the drive source after use. In this case, the holding body is forced to run, which may cause problems such as damage to the holding body or damage to the drive source due to overload.

[Purpose of invention]

This invention provides an acupressure device in which the power supply to the drive source for driving the holder is cut off when the base body is bent beyond a predetermined level, thereby preventing the holder from being forced to travel. It's about doing.

[Summary of the idea]

This idea involves installing a wire on the top side of the base that is pulled when the base is bent, and a switch that cuts off the power supply to the drive source that drives the holder when the wire is pulled. This is an acupressure device in which the holding body is not forcibly driven in a state where the base body is bent more than a predetermined amount.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings. The acupressure device 1 shown in FIGS. 1 and 2 includes a base body 2 in the shape of a rectangular plate. This base body 2 is molded from synthetic resin such as nylon, polypropylene, polyvinyl, or urethane. Further, a large number of cavities 4 having a rectangular cross section are formed in the base body 2 at regular intervals along the longitudinal direction, passing through the base body 2 in the width direction. The plurality of cavities 4 located in the longitudinal center of the base body 2 are communicated with the other ends of slits 6, each of which has one end open to the lower surface of the base body 2, as shown in FIG. This slit 6 is provided over the entire length of the base body 2 in the width direction. Therefore, the base body 2 can be bent into two from the center in the longitudinal direction by the cavity 4 and the slit 6, as shown in FIG.

This pine surge roller 118 is molded from a relatively hard elastic material such as rubber or synthetic resin, and has a large number of substantially hemispherical protrusions 120 protruding from its outer peripheral surface at predetermined intervals in the circumferential direction. .
A stopper 122 is provided on the outer peripheral surface of each collar 116 to prevent the pine surge roller 118 from shifting in the axial direction of the collar 116. Further, a hollow portion 121 is formed along the axial direction in a portion corresponding to each protrusion 120, so that the protrusion 120 is easily elastically deformed inward in the radial direction.

Also, as shown in FIGS. 3 and 13, there is a relatively hard material between two of the three joint surfaces formed by the four collars 116 provided on the hollow shaft 92, except for the center. First pushings 126 made of an elastic material such as rubber are rotatably fitted onto the outside. One end of an arm 129 made of a pair of plate-shaped members 128 is fitted onto each bushing 126, and this arm 129 is attached to the first bushing 1.
It is designed to be able to rotate together with 26. Furthermore, a second bushing 127 made of an elastic material is attached to one end of the arm 129. A receiving member 130 is fixed to the other end of the arm 129. The receiving member 130 is slightly longer than the distance between the pair of arms 129 and has a semicircular arc shape in cross section. A first elastic material 132 such as rubber is adhered to the inner surface of the receiving member 130, and a vibrating device 134 is attached thereon. This vibrating device 134 has a cylindrical case 1 having a smaller radius than the receiving member 130.
It is equipped with 36. This case 136 is the 19th
As shown in the figure, it is held on the receiving member 130 by a screw 140 as a connector via a second elastic material 138 such as rubber. That is, the screw 140 is protruded from the receiving member 130 into the case 136, and the cylindrical second elastic material 1 is attached to the protruding portion.
38 is fitted and prevented from being pulled out by a nut 142. In other words, the case 136 is held on the receiving member 130 by the first and second elastic members 132 and 138 so as to be elastically displaceable in the radial direction.

Inside the case 136 is a DC two-axis motor 144.

6 is attached eccentrically. Therefore, when the two-axis motor 144 operates, the weight 146 rotates eccentrically, causing the case 136 to vibrate. Note that an opening 148 is formed in the case 136, and this opening 148 is connected to the cover plate 1.
50. An elastic material 15 is provided between the inner surface of the cover plate 150 and the two-axis motor 144.
2 is interposed and holds a two-axis motor 144.

On the other hand, one end of a first spring body 154 made of a leaf spring is coupled to the other end of the arm 129, as shown in FIG. This first spring body 15
4 is bent to surround the hollow shaft 92 of the holder 90, and the other end is connected to the support shaft 11 of the holder 90.
Connected to 0. Further, a first auxiliary spring body 156 made of a leaf spring is provided at the other end of the arm 129 and the support shaft 110. Therefore, the arm 129 is rotated in the direction shown by the arrow in FIG. 13 by the urging force of the first spring body 154 to straighten, and the angle of rotation is the same as that of the first auxiliary member. When the spring body 156 is in a straight line, it is held so as not to rotate any further in the direction of the arrow. In this state, the vibrating device 134 is located above the pine surge roller 118, as shown in FIG. moreover,
At the other end of the arm 129 is a second plate spring made of a leaf spring.

There is a receiver 1 on the top surface of the other end located above the
60 is attached. Therefore, when the user lies down on the exterior material 162 covering the upper surface side of the base 2, the first spring body 154, the first auxiliary spring body 156, and the second spring body 158 move as shown in FIG. As shown, the vibration device 134 and the receiving body 160 are elastically deformed and are displaced to a position lower than the pine surge roller 118. In other words, the first spring body 154 is bent so that its middle part is joined to the outer peripheral surface of the second bushing 127, and the first auxiliary spring body 156
bends as if buckling. Furthermore, the middle part of the second spring body 158 comes into contact with the second bushing 127 and is bent into a substantially U-shape. Then, the vibrating device 134 moves the exterior base 16 due to the restoring force of the first spring body 154 and the first auxiliary spring body 156.

Since it is strongly pressed against the user's body, the vibration is well transmitted to the user's body.

As shown in FIG. 18, one end of a pair of first lead wires 164 is electrically connected to the DC two-axis motor 144, respectively. These lead wires 1
The other ends of the support members 64 are respectively led out to the outer surfaces of the pair of supports 94 of the holder 90 and electrically connected to guide members 112 fixed to the conductive belt 86 . The portions of the pair of belts 86 wound around the first drive pulley 70 and the fourth drive pulley 84 are in contact with brushes 166 shown in FIGS. 5 and 20, respectively. Each brush 16
6 has a second lead wire 168 as shown in FIG.
one end is connected. The other ends of these second lead wires 168 are connected to a converter 170 disposed within the case 58 of the drive device 56. This converter 170 converts an AC voltage of 100V to a DC voltage of approximately 10V. Therefore, the DC voltage output from converter 170 is
The two-axis motor 1 is connected from the lead wire 168 through one belt 86 and one first lead wire 164.
44, and flows from the two-axis motor 144 to the converter 170 through the other first lead wire 164, the other belt 86, and the other second lead wire 168. In other words, power can be supplied to the vibrating device 134 and the two-axis motor 144 using the pair of belts 86 that transmit the power of the drive device 56 to the holder 90.

On the other hand, power is supplied to the drive source 64 of the drive device 134 by a switch 172 provided inside the case 58.
It can be shut off by activating the . As shown in FIG. 21, the switch 172 is opposed to a lever 174 whose one end is pivotally attached to the inner surface of one support piece 60 of the mounting plate 62. One end of a wire 176 is connected to the other end of this lever 174. This wire 176 is attached to one guide rail 10 along the longitudinal direction of the holder 17.
It is slidably inserted into a flexible tube 180 held at 8. The other end of the wire 176 protruding from the tube 180 is connected to the coil spring 18.
It is connected to the guide rail 10 via 2. The other end of the wire 176 is connected to the guide rail 10 at a position beyond the first flexible portion 8 formed in the longitudinal center of the base body 2 . Therefore, when the base body 2 is folded together with the guide rail 10 at the first flexible portion 8, the guide rail 10 slides with respect to the base body 2, thereby causing the wire 176 to move in the direction indicated by the arrow in FIG. It is pulled in the direction shown by . Then, this wire 17
A lever 174 connected to one end of the drive source 6 rotates, and this lever 174 operates the switch 172, so that the power supply to the drive source 64 is cut off.

In addition, in FIG. 4, a control device 184 is provided inside the case 58. This control device 184
This makes it possible to control the travel range of the pair of holders 90 along the guide rails 10. Further, on the upper surface of the base 2, a wall member 18 is provided on the outside of the pair of guide rails 10, as shown in FIG.
6 is provided. This wall member 186 is made of a bendable elastic material, such as urethane foam.

The driving device 56 and the vibrating device 134 can be remotely operated by a switch box (not shown).

According to the acupressure device 1 having such a structure, when the user lies face up on the acupressure device 1, the user operates a switch box (not shown) to activate the drive source 64 of the drive device 56. This driving source 6
4 operates and the output shaft 66 rotates in the clockwise direction indicated by the arrow X in FIG.
and the fourth driving pulley 84 rotate in the same direction,
Second driving pulley 76 and third driving pulley 8
0 rotates in the opposite direction. Therefore, the pair of belts 86 are wound around the first drive pulley 70 and the fourth drive pulley 84, respectively, and
Since the belt is fed out from the second driving pulley 76 and the third driving pulley 80 according to the amount of winding, the portion of the belt 86 inserted into the upper passage 20 of the guide rail 10 is shown by the arrow in FIG. Travel in the direction indicated by Z. Then, the wire 115 is pulled by the belt 86 via the mounting plate 119, and the pair of holders 90 are linked to the movement of the belt 86, so that the pine surge rollers 118 provided on these holders 90 Users can receive pine surgery. In addition, if the vibration device 134 is operated by operating the switch box at this time, the vibration device 134 vibrates while elastically deforming the first spring body 154 and the first auxiliary spring body 156. Users can also receive pine surgery.

By the way, in such acupressure device 1,
If you forget to stop the drive source 64 after use, the base 2
If the base body 2 is folded or greatly curved during use, the running resistance of the holder 90 will increase significantly, and the driving source 64, the holder 90, etc. may be damaged. However, in this invention,
When the base body 2 is folded or greatly curved together with the guide rail 10 from the respective flexible parts 8 and 40, the guide rail 10 with only one end fixed to the base body 2 and the other end slidably held is formed. It slides against the base body 2. Then, the wire 176 shown in FIGS. 21 and 22 is pulled in the direction of the arrow, and this wire 176
74 is rotated and the switch 172 is actuated by the lever 174, so that the switch 172 cuts off the power supply to the drive source 64 and stops the movement of the holder 90. In other words, the holding body 90 is not driven in a state where the running resistance is significantly increased compared to the normal operating state.

[Effect of idea]

As described above, this invention provides an acupressure device in which a guide rail is provided on the base, and a holder having a pine surge roller that is movable along the guide rail is driven to travel by a drive source. A wire is provided that is pulled when it is bent, and when the wire is pulled, a switch is activated to cut off the power supply to the drive source. Therefore, the holding body is not driven to travel while the base body is largely bent. In other words, if the running resistance of the holding body increases significantly compared to normal operation, it will stop running, which will prevent the holding body from being forced to run and being damaged, or the drive source from being overloaded and damaged. It can be prevented.
