Description

[Detailed Description of the Invention] [Technical Field of the Invention] 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 is provided with a movable holding body on which a pine surge roller is held on the base body, and by driving this holder back and forth, the pine surge roller can pine-surge a user lying on the upper surface of the base body. I'm starting to do that.

Conventionally, in this type of acupressure device, the one shown in Japanese Utility Model Publication No. 46183/1983 has been proposed in order to enhance the pine surge effect. In other words, in this prior art, a vibration device is provided on the holder that holds the pine surge roller, and the user is not only pressed by the pine surge roller but also pine surged by the vibration action of the vibration device, thereby improving the pine surge effect. I try to measure it.

By the way, since the above-mentioned vibrating device is usually electric, it cannot be operated unless a lead wire is connected and power is supplied. However, since the vibrating device is attached to a holder that is driven back and forth, the lead wire connected to the vibrating device also moves in conjunction with the movement of the holder. Then, a problem arises in that a dedicated running path for the running lead wire must be secured so that the running lead wire does not get entangled with other parts, leading to a complicated structure.

[Purpose of invention]

This idea makes it possible to supply power to the vibrating device installed on the holding body without using a lead wire that is linked to the movement of the holding body, so that the vibrating device can be installed without complicating the structure. An object of the present invention is to provide an acupressure device that does the following.

[Summary of the idea]

In this invention, a holder equipped with a pine surge roller and a vibrating device is driven by a belt made of an electrically conductive material, and power is supplied to the vibrating device through the belt, and a lead wire is used to supply power to the vibrating device. This is an acupressure device that can operate the above-mentioned vibrating device without having to do so.

[Embodiment of the invention] An embodiment of the 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. That is, a first flexible portion 8 is formed in the longitudinally central portion of the base body 2 to allow the base body 2 to be folded.

Further, a portion between the locking portion 14 on the upper surface side of the base portion 12 and one L-shaped piece 18 serves as a guide surface 24 on which wheels 108, which will be described later, run.

Although the details of the guide rail 10 are not shown, only one end in the longitudinal direction is screwed and fixed to the base body 2, and the other part is slidably held by a support 28 shown in FIG. 3. Therefore, the other end of the guide rail 10 is expandable and retractable with respect to the base body 2. Further, as shown in FIGS. 9 and 10, the portion of the guide rail 10 corresponding to the first flexible portion 8 of the base body 2, that is, the central portion in the longitudinal direction, is connected to the locking portion 14 of the guide rail 10 and the support portion 14 of the guide rail 10, as shown in FIGS. Part 1

A drive source 64 in which a speed reducer and a motor are integrated is attached to this mounting plate 62. An output shaft 66 of this drive source 64 projects toward the outer surface of one of the support pieces 60 . A first gear 68 and a first driving pulley 70 are fitted onto the output shaft 66 . Further, the mounting plate 62 is provided with a first mounting shaft 72 whose both ends are rotatably supported by the support piece 60. Both ends of the mounting shaft 72 protrude toward the outer surface of the support piece 60, and a second gear 74 and a second driving pulley 76 paired with the first driving pulley 70 are attached to one end of the mounting shaft 72.

A fourth gear 82 meshing with the third gear 78 and a fourth driving pulley 84 paired with the third driving pulley 80 are fitted onto the second mounting shaft 81. ing. Therefore, when the output shaft 66 is rotationally driven, the first gear 6
8 and the second gear 74 rotate in opposite directions, and the third gear 78 and the fourth gear 82 rotate in opposite directions. Note that the first to fourth gears rotate at the same number of rotations.

As a power transmission condition, one end of a pair of belts 86 formed in a band shape from a conductive material such as a steel plate is fixed to the first drive pulley 70 and the fourth drive pulley 84, respectively. It is wrapped around. This belt 86 is passed from the first and fourth driving pulleys 70, 84 to the upper passage 20 of the guide rail 10, as shown in FIG. The midway portion led out from the upper passage 20 is hung on a support pulley 48 provided on the pedestal 42. The belt 86 is attached to the support pulley 4

This wheel 108 runs on the guide surface 24 of the guide rail 10. Further, rubber 109 is provided on the outer peripheral surface of the wheel 108 over the entire circumference.
As shown in FIGS. 11 and 15, a substantially T-shaped guide member 11 is provided at the lower end of the lower surface of the support 94.
One horizontal side of 2 is attached and fixed. The other vertical side of the guide member 112 protrudes from the lower end of the support 94, and a winding portion 113 is bent at this protruding portion. A midway portion of a bendable wire 115 serving as a connecting member is slidably inserted into this winding portion 113. Mounting fittings 117 shown in FIG. 16 are attached to both ends of this wire 115, and these fittings 117 are fixed to the upper outer surface of the support 94 with screws. Furthermore, the intermediate portions of the wire 115 located on both sides of the winding portion 113 are connected to a pair of mounting plates 11 fixed to the upper surface of the portion of the belt 86 that is inserted into the upper passage 14, respectively.
It is connected to 9. That is, the mounting plate 119 is formed with an insertion portion 121 as shown in FIG.
The wire 115 is inserted through this insertion portion 121 . Therefore, the wire 115 is bent into a substantially triangular shape with the base between the pair of mounting plates 119, so that the holder 90 is linked to the running of the belt 86 via the mounting plate 119. It's summery.

Furthermore, four collars 116 are provided on the hollow shaft 92 of the holder 90 so as to be rotatable and not to shift in the axial direction. 116 colors each
A pine surge roller 118 is attached to the pine surge roller 118. 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 bushings 126 made of an elastic material such as rubber are rotatably fitted onto the outside of each bushing. One end of an arm 129 made of a pair of plate-like 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. That is, 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.
is retained and fixed. As shown in FIG.
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 plate 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
One end of the spring body 158 is fixed. The other end side of the second spring body 158 extends in an obliquely upward direction away from the vibrating device 134.
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 such that its midway portion is joined to the outer circumferential surface of the second bushing 127, and the first auxiliary spring body 156 is bent so as to buckle. 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 162 due to the restoring force of the first spring body 154 and the first auxiliary spring body 156.
It is pressed against the user's body through the
It is also urged in that direction by the restoring force of the second spring body 158. Therefore, since the vibration device 134 is strongly pressed against the user's body, the vibrations are 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 surface 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.
is connected at one end. 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 two-axis motor 144 of the vibrating device 134 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.
2 to the guide rail 10. 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 drive 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 driving pulley 70 and the fourth driving 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 interlocked with the running of the belt 86, so that the pine surge rollers 118 provided on these holders 90 Users can receive pine surgery. Further, at this time, if the vibration device 134 is operated by operating the switch box, this vibration device 134 is activated by the first spring body 154.
Since the first auxiliary spring body 156 and the first auxiliary spring body 156 vibrate while being elastically deformed, the user can also receive a pine surge due to this vibration.

Incidentally, the DC voltage converted by the converter 170 is supplied to the vibration device 134 via the conductive belt 86. That is, the vibration device 134 and the belt 86 are electrically connected via the first lead wire 164 and the guide member 112,
Since the belt 86 and the converter 170 are electrically connected via the second lead wire 168 and the brush 166, the DC voltage output from the converter 170 can be supplied to the vibration device 134. According to such a power feeding structure, the vibration device 134 and the converter 170 are linked to the movement of the holding bodies 90 in order to feed power using the belt 86 which is naturally necessary to drive the pair of holding bodies 90. There is no need to connect using lead wires.

[Effect of idea]

As described above, in this invention, a pine surge roller and a vibrating device are provided on a holding body that is driven to run by a belt, the belt is made of a conductive material, and the power to the vibrating device is connected to the belt. I decided to do this using . Therefore, since it is not necessary to connect the lead wire that is linked to the movement of the holder to the vibration device, there is no need to secure a running path for the lead wire, and the structure can be simplified. Furthermore, since a belt, which is naturally necessary to drive the holding body, is used, the structure can also be simplified.
