Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention relates to a pine surge device that pine-surges a user by means of a pine-surge roller that is reciprocated on a base.

(Prior Art) In general, a pine surge device has a base body which is provided with a movable holder holding a pine surge roller, and by reciprocating this holder, a user lying on the upper surface of the base is It is now possible to perform pine surge with a pine surge roller.

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, 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 this structure in which the vibration device is fixedly provided on the holding body, the vibration plate is strongly pressed by the weight of the user, and the pushing body no longer vibrates well, causing vibrations. There were cases where the pine surge effect of the device was reduced.

(Problem to be solved by the invention) As described above, in the conventional pine surge device having a vibration device, when the vibration device is strongly pressed by the user's weight, it becomes difficult to vibrate and the pine surge effect decreases. Something happened.

This idea was made based on the above circumstances, and its purpose was to prevent the pine surge effect caused by vibration from decreasing even when the vibration device is pressed by the user's weight. The purpose of the present invention is to provide a pine surge device.

[Structure of the idea]

(Means and effects for solving the problem) In order to solve the above problem, this invention includes a base body, a pair of guide rails provided parallel to and spaced apart from each other on the upper surface of the base body, and a movable member that can run freely on the guide rails. a holder provided on the holder, a pine surge roller attached to a shaft provided on the holder, an arm rotatably connected at one end to the shaft and provided with a vibration device at the other end, and the guide rail. a power transmission strip that is movably inserted into a passage formed in the passageway; a drive source that drives the power transmission strip to run;
Provided at a portion of the power transmission strip connected to the holding body and elastically contacts the inner surface of the passage of the guide rail to prevent the power transmission strip from vibrating due to vibrations transmitted from the vibration device. A spring body having one end connected to the other end of the arm, and a balancer provided at the other end of the spring body.

According to such a configuration, when the user lies supine on the base and the balancer is pressed to elastically deform the spring body, the vibration device is strongly pressed against the user's body by the reaction force of the spring body. Therefore, the vibration of the vibrating device is strongly transmitted to the user, and the vibration of the vibrating device is also transmitted to the balancer via the spring body, so the user also receives vibration from the balancer, and the vibration of the vibrating device is transmitted to the power transmission strip. Even if the power transmission strip is transmitted to the power source, the elastic presser prevents the power transmission strip from vibrating, so that it does not collide with the guide rail and generate noise.

4 includes a case 136 having a semi-cylindrical portion with a smaller radius than the receiving member 130. As shown in FIG. 20, the case 136 is held on the receiving member 130 by a screw 140 serving as a connector via a second elastic material 138 such as rubber. That is, the screw 140 is projected from the receiving member 130 into the case 136, and the cylindrical second elastic member 138 is fitted into the projection, and is prevented from being pulled out by the nut 142. In other words, the case 136 includes the first and second elastic members 132,
138 on the receiving member 130 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 a cover plate 150 is fixed to the opening on the upper surface side of the case 136 with screws. The inner surface of this cover plate 150 and the two-axis motor 1
An elastic material 152 is interposed between the two-axis motor 144 and the two-axis motor 144 .

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, when the user lies down on the exterior material 162 covering the upper surface side of the base 2, the spring body 158 is elastically deformed as shown in FIG. Displaced to approximately the same height as. In other words, the middle part of the spring body 158 comes into contact with the second bushing 127 and is bent into a substantially U-shape. The vibrating device 134 is biased 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 screwed onto the lower surface of the other end of the pair of spring bodies 158 to which the balancer 160 is attached. One end side of a first wire 173 serving as a cord forming a regulating means is fixed to the set screw 172a.
Also, set screws 17 are provided on both end surfaces of the balancer 160.
One end of a second wire 174, which also serves as a regulating means, is fixed by 2b. The first wire 173 has a loop shape, and the loop is engaged with one of the support shafts 110 that rotatably supports the wheels 108 of the support 94. The other end of the second wire 174 is fixed to the support 94 of the other holder 90 on which the vibration device 134 is not provided, 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 173 and the second wire 174 to form the wires 173, which are in the state shown in FIG. 174 is restricted from being displaced upwards beyond the taut state.

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 third wire 175 loop is connected to the support 94 of the holder 90.
is engaged with the other support shaft 110 of. Thereby, the arm 129 is restricted from displacing upward beyond the state in which the third wire 175 shown in FIG. 11 is stretched. Note that a belt may be used instead of a wire as the cable member.

As shown in FIG. 13, the spring body 158 has a structure in which a strip-shaped plate spring 158a and a strip-shaped protection plate 158b made of nylon or polypropylene are superposed vertically, and these are covered with an outer skin 158c made of synthetic resin. , the upper band-shaped protection plate 158b prevents damage to the exterior material 162.

The DC two-axis motor 144 of the vibration device 134 has a pair of first lead wires 1 as shown in FIG.
One ends of 64 are electrically connected to each other.
The other ends of these lead wires 164 are connected to the holder 9.
The guide member 1 is led out to the outer surface side of the pair of supports 94 and is fixed to the conductive belt 86.
It is electrically connected to 12. The portions of the pair of belts 86 wound around the first driving pulley 70 and the fourth driving pulley 84 each have a fifth
The brushes 166 shown in the figure and FIG. 21 are in contact. Each brush 166 has a second brush as shown in FIG.
One end of a lead wire 168 is connected. The other end of these second lead wires 168 is connected to the drive device 5.
Converter 170 disposed within case 58 of 6
It is connected to the. This converter 170
Converts 100V AC voltage to approximately 10V DC voltage.
Therefore, the DC voltage output from the converter 170 is inputted from one of the second lead wires 168 to the two-axis motor 144 through one of the belts 86 and one of the first lead wires 164. 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,
The two-axis motor 144 of the vibrating device 134 can be powered using a pair of belts 86.

Further, as shown in FIG. 22, a switch mechanism 190 is provided on the upper surface of the base body 2 at one end in the width direction. 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 more than a predetermined amount. That is,
A spring portion 192 as a flexible portion is formed in the middle of one end of the base 2 in the width direction, and a wire 194 having one end fixed to the midway of the base 2 is disposed along the longitudinal direction of the base. 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 194 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, 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 opposite to the lever 196.

A midway portion of the wire 194 is slidably held by a holder 200 shown in FIG. 25. This holder 200 has a thickness of, for example, 0.3 mm.
One flange 30 of the rail slider 28 that slidably supports the guide rail 10 is formed by bending a synthetic resin film in two and making a notch 202 at one end in the width direction of the overlapping part. It is provided to be engaged with. The wire rod 194 is inserted between the overlapping 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 above wire rod 194
is the lever 1 when the base body 2 is unfolded.
96 is pulled by a wire 194, thereby causing the actuator 198 of the shutoff switch 198 to
a is pressed, this switch 198 is turned on, and power can be supplied to the drive source 64. When the base body 2 is bent from the first flexible portion 8 as shown by the chain line in FIG.
The spring portion 192 located at a position corresponding to the base body 2
Since it floats up from the upper surface and is bent, the other end of the wire 194 is at the 22nd position with respect to the base 2 by that length.
It slides in the direction of the drive device 56 shown by the arrow in the figure. As a result, the lever 196 connected to the other end of the wire 194 is moved to the actuator 1 of the cutoff switch 198.
Since it rotates in the direction away from 98a, the cutoff switch 198 is turned off and the power supply to the drive source 64 is cut off. That is, even if the base body 2 is folded while the drive device 56 is activated,
This drive device 56 can be stopped automatically.

In addition, in FIG. 4, a control device 203 is provided inside the case 58. This control device 203
This makes it possible to 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.

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 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 second Pulley 76 and third driving pulley 80
and rotate in the opposite direction. Therefore, the pair of belts 86 are connected to the first drive pulley 70 and the fourth drive pulley, respectively.
Because it is wound up on the driving pulley 84 and sent out from the second driving pulley 76 and the third driving pulley 80 according to the amount of winding,
Upper passage 2 of the guide rail 10 of the belt 86
0 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 pine surge rollers 118 provided on these holders 90 Users can receive pine surgery. Also, at this time, if the switch box is operated to activate the vibration device 134,
As this vibration device 134 vibrates, the vibration is also transmitted to the balancer 160 via the spring body 158, so the user receives pine surge over a wide range of the body due to the vibration of the vibration device 134 and the balancer 160. be able to.

By the way, in the acupressure device having the above configuration, when the user lies supine on the base 162, the vibration device 13
The other end of the spring body 158 to which the balancer 160 is attached, which is located above the spring 4, is elastically deformed downward from the state shown in FIG. 11 as shown in FIG. 12.
In other words, the spring body 58 is elastically deformed into a curved shape.
Then, the restoring force of the spring body 158 urges the other end of the arm 129 to which the vibration device 134 is attached in the upward direction, so that the vibration device 134
is strongly pressed against the user's body via the exterior fabric 162. Therefore, the vibration device 134
The vibrations are strongly transmitted to the user's body, increasing the pine surge effect.

Further, the other end of the spring body 158 to which the balancer 160 is attached is prevented from being displaced too much upwards than the state shown in FIG. 11 by the first wire 173 and the second wire 174. has been done. In other words, even if the body 158 is elastically deformed due to the user lying supine on the exterior material 162 moving his or her body, the raised position of the balancer 160 remains the same as that of the first wire 173, the second wire 173,
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 is pulled against a part of the user's body. It may take some time. Then, the spring body 158 to which the balancer 160 is attached may be bent or broken. However, the balancer 160 of the spring body 158
The end portion to which is attached is restricted from being displaced above a predetermined height by a first wire 173 and a 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 158 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 reaction force causes the arm 129 to
The other end side rises too much, which causes the arm 12
This also prevents the vibration device 134 attached to the other end of the device 9 from protruding too far upward and getting caught on the user's body.

Furthermore, when the vibration device 134 operates, the vibrations are transmitted to the support 94 of the holding body 90, the wire 115 connecting the holding body 90 and the belt 86, and the wire 1.
15 is transmitted to the belt 86 via a mounting plate 119 that connects the belt 86 to the belt 86. In particular, of the pair of mounting plates 119, the mounting plate 119 located on the vibration device 134 side vibrates more strongly. As a result, the belt 86 may vibrate within the upper passage 20 of the rail 10 and may hit the pair of L-shaped pieces 18 forming the upper passage 20, producing noise.

However, the wire 115 is
An elastic presser body 109 is provided on one mounting plate 119 located on the vibrating device 134 side, which is a portion connected to are in contact. This prevents the belt 86 from vibrating even if the vibrations of the vibrator 134 are transmitted to the wire 115, thereby preventing the belt 86 and the L-shaped piece 18 from colliding and generating noise. be done.

In addition, in the above embodiment, in order to prevent the other end side of the spring body from rising too much, the first wire and the second wire are connected to each other.
However, even if only one of the wires is used, it is possible to prevent the other end of the spring body from rising too much.

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

[Effect of idea]

As described above, according to this 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 this arm, and one end of the spring body is connected. A balancer is provided at the other end of this spring body, and an elastic presser is provided on the power transmission strip that drives the holding body, and the elastic presser is attached to the passage of the guide rail through which the power transmission strip is inserted. I tried to make it come into contact with the target.

Therefore, when the spring body is elastically deformed by the user's weight, its restoring force biases the arm in a direction in which the other end to which the vibrating device is attached rises. The vibration device is pressed against the user's body, which can enhance the pine surge effect. Further, since the vibrations of the vibrating device are also transmitted to the balancer via the spring body, the user can also be massaged by this balancer. Furthermore, the power transmission strip is prevented from vibrating due to the vibration transmitted from the vibrating device by the elastic presser that is in elastic contact with the passage of the guide rail. There will be no collision or noise.
