Conventionally, in this type of acupressure device, the one shown in Japanese Utility Model Publication No. 59-46183 has been proposed in order to enhance the pine surge effect. In other words, this prior art is designed to improve the pine surge effect by installing a vibrating device on the holder that holds the pine surge roller, and not only pressing the user with the pine surge roller, but also pine surge by the vibration action of the vibration device. I have to.

By the way, the above-mentioned vibrating device is fixedly provided on a holder that is driven to travel, and massages the user with a pushing body provided on the vibrating diaphragm. However, with a structure in which such a vibrating device is fixedly provided on a holder, the pushing body does not vibrate well because the diaphragm is strongly pressed by the weight of the user.
The pine surge effect caused by the vibration device was sometimes reduced.

(Problems to be Solved by the Invention) As described above, in the conventional pine surge device having a vibrating device, when the vibrating device is strongly pressed by the user's weight,
There were cases where it became difficult to vibrate and the pine surge effect decreased.

This invention was made based on the above circumstances, and its purpose is to provide a pine surge device in which the pine surge effect caused by vibration does not deteriorate even when the vibration device is pressed by the user's weight. There is a particular thing.

A base portion 109b formed on one end side shown in FIG. 16 is fixedly provided on the upper surface of one of the mounting plates 119. The spring portion 109a is connected to the upper passage 20 of the guide rail 10.
The inner surfaces of the pair of L-shaped pieces 18 forming the L-shaped pieces are loosely in contact with each other or are opposed to each other with a slight gap between them. As a result, the portion of the belt 86 to which the one mounting body 119 is fixed is prevented from vibrating like waves due to the elastic contact of the spring portion 109a with the C-shaped piece 18. ing.

Further, as shown in FIG. 3, four collars 116 are provided on the hollow shaft 92 of the holder 90 in a state that the collars 116 are rotatable and do not shift in the axial direction. A pine surge roller 118 is attached to each collar 116. 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.

Moreover, as shown in FIGS. 3 and 12, 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 each having an inner circumferential surface made of an elastic material such as rubber and having an uneven shape along the circumferential direction are rotatably fitted. One end of an arm 129 made of a pair of plate-shaped members 128 (only one shown) is fitted onto each bushing 126, and this arm 129 can rotate together with the first bushing 126. Further, a second bushing 127 made of an elastic material is attached to one end of the arm 129. A member 130 is fixed to the other end of the arm 129, and is slightly longer than the distance between the pair of arms 129 and has a semicircular cross section. In this receiver, a first elastic material 132 such as rubber is adhered to the inner surface of a member 130, and a vibrating device 1
34 is attached. This vibrating device 134 includes a case 136 having a semi-cylindrical portion having a radius smaller than that of the member 130. In this case 136, as shown in FIG. 20, the receiver is held on the member 130 by a screw 140 as a connecting member via a second elastic material 138 such as rubber. In other words, the screw 140 is connected to the member 130.
The cylindrical second elastic member 138 is fitted into the protrusion into the case 136, and is prevented from being pulled out by a nut 142. In other words, case 136
is the first. The receiver is held on the member 130 by second elastic members 132, 138 so as to be elastically displaceable in the radial direction.

A DC two-axis motor 144 is held and fixed within the case 136. As shown in FIG. 18, weights 146 are eccentrically attached to the shafts of the two-shaft motor 144. Therefore, when the two-axis motor 144 operates, the dust 146 rotates eccentrically, causing the case 13 to rotate.
6 is designed to vibrate. Note that a cover plate 150 is fixed to the opening on the upper surface side of the case 136 with screws. An elastic material 152 is interposed between the inner surface of the cover plate 150 and the two-shaft motor 144 to hold the two-shaft motor 144. Further, at the other end of the am 129, a twelfth
As shown in the figure and FIG. 13, one end of a spring body 158 made of a band-shaped leaf spring is fixed. The other end of the spring body 158 extends diagonally upward away from the vibrating device 134, and a balancer 160 is fixed to the upper surface of the other end located above the vibrating device 134 with a screw 161. Therefore, the exterior fabric 1 covering the upper surface side of the base 2
When the user lies down on 62, the spring body 158
As shown in FIG. 2, the vibrator 134 and the receiver body 160 are elastically deformed and are displaced to approximately the same height as the pine surge roller 118. In other words, the middle part of the spring body 158 hits the second bushing 127 and is bent into a substantially U-shape.

Then, the vibrating device 134 is urged upward, toward the exterior base 162, by the restoring force of the 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. 12, a set screw 172a is provided on the lower surface of the other end of the pair of spring bodies 158 to which the balancer 160 is attached.
Or screwed on. One end side of a first wire 173, which is a blank body forming a regulating means, is fixed to this set screw 172a. Further, a second set screw 172b is provided on both end faces of the balancer 160 to serve as a regulating means.
One end of the wire 174 is fixed. The first wire 173 has a loop shape, and the loop is connected to one support shaft 11 that rotatably supports the wheel 108 of the support 94.
0 is engaged. The other end of the second wire 174 is fixed to the support 94 of the other holder 90, which is not provided with the vibration device 134, as shown in FIGS. 19 and 2. Therefore, the other end of the spring body 158 to which the balancer 160 is attached is connected to the first wire 17.
3 and the second wire 174, the wires 173, 174 are prevented from being displaced upward from the state shown in FIG. 11, in which they are stretched.

Further, one end of a third wire 175 having a loop shape is fixed to the other end of the arm 129 by a set screw 176. This loop of the third wire 175 is engaged with the other support shaft 110 of the support 94 of the holder 90. Thereby, the arm 129
The third wire 175 is restricted from being displaced upward from the tensioned state shown in the figure. Note that a belt may be used instead of the wire as the element body.

The spring body 158 is a strip-shaped leaf spring 1 as shown in FIG.
58a and a band-shaped protective plate 15 made of nylon or polypropylene
8b in the vertical direction, and these are covered with a synthetic resin outer cover 158C, and the upper band-shaped protective plate 158b prevents damage to the outer cover N162.

The DC two-axis motor 144 of the vibration device 134 has an 18th
As shown in the figure, one end of a pair of first lead wires 164 is electrically connected to each other. These lead wires 164
The other ends 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 21, respectively. Each brush 1
66 is connected to one end of a second lead wire 168, as shown in FIG. 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 the converter 170 passes from one second lead wire 168 to one belt 86 and one first lead wire 164 to the two-axis motor 1.
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.

Further, a switch mechanism 190 is provided on the upper surface of the base body 2 at one end in the width direction, as shown in FIG. This switch mechanism 190 is for forcibly cutting off the power to the drive source 64 of the drive device 56 to stop the movement of the holder 90 when the base body 2 is bent beyond a predetermined degree. That is, a spring part 192 as a flexible part is formed in the middle of one end of the base 2 in the width direction, and a wire 194 with one end fixed to the middle of the base 2 is arranged along the longitudinal direction of the base. There is. The spring portion 192 is located at a position corresponding to the first flexible portion 8 of the base body 2. Although the wire rod 1-94 can be bent, it is made of a material such as a steel wire that has a certain degree of rigidity. The other end of the wire 194 is connected to the other end of a lever 196, one end of which is rotatably attached to one support side 60 of the mounting plate 62 of the drive device 56.

A cutoff switch 198 is provided on the support side 60 at a position facing the lever 196.

)) The wire rod 194 is slidably held by a holder 200 shown in FIG. 25.

This holder 200 is made by, for example, bending a 0.3 mm thick synthetic resin film in two and drilling a notch 202 at one end in the width direction of the overlapping part.The guide rail 10 is slid through the notch 202. It is provided so as to be engaged with one flange 30 of the freely supported rail slider 28. The wire rod 194 is inserted between the polymerized films of the holder 200.

The cutoff switch 198 is actuated by the lever 196 to cut off power supply to the drive source 64. The wire rod 194 is such that when the base body 2 is unfolded, the lever] 96 is pulled by the wire rod 194, which presses the actuator 198a of the cutoff switch 198, turning on the switch 198 and turning on the drive source. It is possible to supply power to 64. When the base body 2 is bent from the first flexible portion 8 as shown by the chain line in FIG. Since the wire rod 194 is raised and bent, the other end of the wire rod 194 slides by that length with respect to the base body 2 in the direction of the drive device 56 shown by the arrow in FIG. 2ij. As a result, the lever 196 connected to the other end of the wire 194 rotates in a direction away from the actuator 198a of the cutoff switch 198, so the cutoff switch 198 is turned off and the power supply to the drive source 64 is cut off. state. That is, even if the base body 2 is folded while the drive device 56 is in operation, the drive device 56 can be automatically stopped.

In addition, in FIG. 4, a restraining device 203 is installed inside the case 58.
is provided. This control device 203 can control the travel range of the pair of holders 90 along the guide rails 10. Furthermore, a wall member 204 is provided on the upper surface of the base body 2 on the outside of the pair of guide rails 10, as shown in FIG. 1 or 3. This wall member 204 is made of a bendable elastic material, such as urethane foam.

According to the acupressure device 1 having such a structure, the acupressure device 1
When the user lies face up, the user operates a switch box (not shown) to activate the drive source 64 of the drive device 56. When this drive source 64 operates and the output shaft 66 rotates in the clockwise direction indicated by arrow X in FIG. 5, the first drive pulley 70 and the fourth drive pulley 84 rotate in the same direction, and the The second driving pulley 76 and the third driving pulley 80 rotate in opposite directions. Therefore, the pair of belts 86 are wound around the first driving pulley 70 and the fourth driving pulley 84, respectively, and are wound around the second driving pulley 76 and the third driving pulley 84 depending on the amount of winding. The guide rail 10 of the belt 86 is fed out from the pulley 80.
The portion inserted into the upper passage 20 runs in the direction shown by arrow Z in FIG. 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 user can perform the pine surge using the pine surge rollers 118 provided on the holders 90. can receive. Also,
At this time, if the user operates the switch box to activate the vibration device 134, the vibration device 134 vibrates and the vibration is also transmitted to the balancer 160 via the spring body 158. and balancer 16
By vibrating with 0, you can receive a wide range of body + massage.

By the way, in the acupressure device having the above configuration, the exterior material 162
When the user lies down, the other end of the spring body 158 to which the balancer 160 is attached, which is located above the vibration device 134, is elastically deformed downward from the state shown in FIG. 11 as shown in FIG. 12. do. In other words, the spring body 58 is elastically deformed in a square shape. Then, the restoring force of the spring body 158 urges the other end of the arm 129 to which the vibrating device 134 is attached in the upward direction, so that the vibrating device 134 strongly hits the user's body via the exterior fabric 162. You will be forced to do so. Therefore, the vibration of the vibrating device 134 is strongly transmitted to the user's body, and the pincer effect can be enhanced.

Further, the other end of the spring body 158 to which the balancer 160 is attached is prevented from being displaced too much upwardly than the state shown in FIG. 11 by the first wire 173 and the second wire 174. There is. That is, even if the spring body 158 is elastically deformed due to the user lying down on the exterior material 162 moving his or her body, the raised position of the balancer 160 is regulated by the first and second wires 173 and 174. Therefore, the balancer 160 attached to the other end of the spring body 158 does not protrude too far upward.

When the holding body 90 is driven to run in the direction shown by arrow A in FIG. 11 with the balancer 160 protruding upward while pressing the exterior material 162, the balancer 160 may be caught on a part of the user's body. There is. Then, balancer 16
The spring body 158 to which 0 is attached may be bent or broken. However, the end of the spring body 158 to which the balancer 160 is attached is prevented from being displaced above a predetermined height by the first wire 173 and the second wire 174. Therefore, it is reliably prevented that the balancer 160 protrudes too far upward and gets caught on a part of the user's body, causing the spring body 58 to bend or break.

Further, the other end of the arm 129 is prevented from rising too high by a third wire 175.

As a result, when the other end of the spring body 158 is strongly pressed down, the other end of the arm 129 rises too much due to the reaction force, which causes the vibration device 134 attached to the other end of the arm 129 to move upward. It is also prevented from protruding too much and getting caught on the user's body.

When the vibration device 134 is activated, the vibration is transmitted to the belt 86 through the support 94 of the holder 90, the wire 115 that connects the holder 90 and the belt 86, and the mounting plate 119 that connects the wire 115 to the belt 86. Conveyed.

In particular, of the pair of mounting plates 119, the mounting plate 119 located on the vibration device 134 side vibrates more strongly. Thereby, the belt 86 vibrates within the upper passage 20 of the rail 10, and the pair of L-shaped pieces 18 forming the upper passage 20
There is a risk that it will hit and make noise.

However, one mounting plate 119 located on the vibrating device 134 side where the wire 115 is connected to the belt 86 is provided with an elastic presser body 109, and a pair of spring portions 109a of the attachment plate 119 are attached to the L of the upper passage 20. It is in elastic contact with the letter-shaped piece 18.

This prevents the belt 86 from vibrating even if the vibrations of the vibrating device 134 are transmitted to the wire 115, thereby preventing the belt 86 and the L-shaped piece 18 from colliding and generating noise. Ru. In addition, in the above embodiment, in order to prevent the other end side of the spring body from rising too much, the first
Although the above wire and the second wire are provided, even if only one of the wires is used, it is possible to prevent the other end of the spring body from rising too high.

Furthermore, elastic pressers for preventing vibration of the belt may be provided at two locations where the wire is connected to the belt.

[Effects of the Invention] As described above, according to the present invention, one end of the arm is rotatably attached to the shaft of the holder to which the pine surge roller is attached, a vibration device is provided at the other end of the arm, and the spring body One end of the spring body is connected to the other end of the spring body, and a balancer is provided at the other end of the spring body, and the displacement of the other end of the spring body above a predetermined height is restricted by a regulating means. Therefore, when the spring body is elastically deformed by the user's weight, its restoring force urges the arm toward the other end to which the vibrating device is attached in the upward direction, so that the vibrating device can be used. It can be pressed against the person's body and enhance the pine surge effect. Further, since the vibration of the vibrating device is also transmitted to the balancer via the spring body, the user can be massaged by the balancer. Furthermore, since the raising position of the other end of the spring body, where the balancer is provided, is restricted by a regulating means, the balancer may protrude too far upwards when the holding body is traveling, and may catch on the user's body or the like, causing the spring This can prevent the body from breaking.
