Description

[Detailed Description of the Invention] The present invention relates to an improvement of an acupressure device that massages the human body by reciprocating an acupressure roller.

In general, this type of acupressure device has a support body that is movable inside a book with an open top surface and a cloth stretched over the open surface, and a roller shaft that is installed on this support body. The acupressure roller is rotatably fitted.

By causing the support body to reciprocate by a drive source provided within the main body, the user lying on the cloth is pressed by the acupressure roller and massaged.

By the way, in the conventional acupressure device, the acupressure roller has a simple cylindrical shape, as described above.

Therefore, the acupressure roller running inside the main body together with the support does not press strongly against the user, so that a sufficient pine surge effect cannot be obtained.

Therefore, it has recently been considered to improve the pine surge effect of the acupressure roller by providing a protrusion on the outer peripheral surface of the acupressure roller.

However, when a protrusion is provided on the outer circumferential surface of the acupressure roller, the pressing action of the protrusion is too strong compared to a conventional acupressure roller with a flat outer circumferential surface, so a problem arises in that a suitable pine surge effect cannot be obtained.

The present invention was developed based on the above circumstances, and its purpose is to provide a protrusion on the outer circumferential surface of the acupressure roller, and to make the protrusion easy to elastically displace.
To provide an acupressure device capable of obtaining a good pine surge effect.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a bottomed box-shaped main body having an open top surface and a frame body 1b having a cloth 1a stretched over the open surface.

Inside this main body 1, a pair of rails 2 and 3 are laid in parallel along the longitudinal direction of the main body 1, and a support frame 3 is provided on these rails 2 and 2 so as to be freely movable.

This support frame 3 consists of a pair of supports 4 spaced apart in parallel.

... rotatably supports the roller shafts 7, 7 fitted therein.

Furthermore, wheels 9 are provided on both sides of the supports 4, 4 to be in contact with the rails 2, 2.

Furthermore, a drive source 12 in which a motor 10 and a transmission 11 are integrated is disposed at one end in the longitudinal direction within the main body 1, and an output shaft 14 on which a drive pulley 13 is fitted is connected from the drive source 12.
is projected horizontally.

Further, a driven pulley 15 is provided at the other end of the main body 1 with its axis perpendicular, and a wire 16 is stretched between the driven pulley sleeve and the drive boob 1113.

That is, this wire 16 connects the middle part to the drive pulley 1.
3 and a driven pulley 15, and both ends thereof are located within the support frame 3.

Pins 18.18 each having a collar 17.17 are fixed to both ends of this wire 16, and these pins 18.1
8 are connected via springs 19.

A first interlocking bar 20 and a second interlocking bar 21 made of hard steel wire are fitted with winding portions 20a and 21b formed at one end of each of the pins 18, 18, respectively.

Each of these interlocking bars 20,21 is guided in a direction opposite to the spring 19, and the other end is connected to the support frame 3.
The supports 4, 4 protruding from the lower surfaces are slidably supported by the parts 22, 22, and the supports 4, 4 are slidably supported by the parts 22, 22.
, 22 are bent into an L-shape to prevent the interlocking bar 20.21 from coming off the receiving portion 22.22.

Further, the contact length of the wire 16 with the drive pulley 13 is increased by an auxiliary pulley 23 disposed near the drive pulley 13.

Therefore, the drive source 12 operates and the drive pulley 13
When the wire 16 runs in the direction shown by the arrow in FIG. The support frame 3 is pulled and runs.

At this time, the elongation of the wire 16 is absorbed by the restoring force of the bower 19 interposed in the wire 16, and the wire 16 is
Since the contact state between the drive pulley 6 and the drive pulley 13 is maintained constant, the support frame 3 can run smoothly.

On the other hand, the rails 2, 2 have a plurality of convex portions 2a...
・ is provided at the corresponding position, and this convex portion 2a...
・Support frame 3 running on rails 2, 2 by
In other words, the acupressure rollers 6 are moved upward.

As shown in FIG. 5, when the user M lies down on the cloth 1a stretched over the opening surface of the main body 1, the convex portions 2a... The acupressure rollers 6 are provided at portions corresponding to the neck and feet of the human body so as to press with uniform force.

Further, a control bar 24 is supported on one inner surface of the main body 1 along the longitudinal direction of the main body 1 by support portions 25 and 25 so as to be slidable at both ends thereof.

The control bar 24 is made of hard steel wire, and has first to third engaging portions 26a at its longitudinal midpoint and at both ends.

26 b and 26 C are bent so as to protrude in the horizontal direction.

These engaging portions 26 a , 26 b , 26 C are attached to the lower surface of one of the supports 4 of the support frame 3 , that is, the support 4 located on the drive source 12 side, as the support frame 3 travels. As shown in FIG. 4, it engages with a protruding drive pin 27 and slides.

One end of the control bar 24 located on the driving source 12 side forms an actuating part 28 bent into a hairpin shape, and a micro switch 29 is disposed opposite to this actuating part 28.

Therefore, when the control bar 24 slides, its operating portion 28 turns the microswitch 29 to 0N.
It is set to turn off.

This microswitch 29 is electrically connected to the drive source 12, and this ON-OFF operation causes the motor 10 of the drive source 12 to rotate in forward and reverse directions.

On the other hand, an operation box 30 is provided on one outer surface of the main body 1, and this operation box 30 is provided with a switching mechanism 31.

The switching mechanism 31 includes a switching arm 32 pivotally supported on the operation box 30 and an operating rod 33 having one end fixed to the switching arm 32 and the other end connected to the control bar 24. When the control bar 24 is rotated in the clockwise direction indicated by the arrow in FIG. 2, the control bar 24 is curved and deformed as indicated by the chain line in the figure.

Then, when the control bar 24 is curved and deformed, the central engaging part 26 b of the three retaining parts is largely displaced toward the inner surface of one side of the main body 1. The drive pin 27 protruding from the lower surface of one of the supports 4 of 3 does not engage with the drive pin 27.

Further, the operation box 30 is provided with a timer 33 for setting the operating time of the drive source 12.

Further, stoppers 34 for preventing the support frame 3 from coming off from the rails 2, 2 are provided in the main body 1 so as to be located at both ends of the rails 2, 2. An elastic material 35 is attached to the inner bottom surface of the cloth 1, and this elastic material 35 prevents the user's body from directly hitting the wire 16 etc. when the cloth 1a is bent.

On the other hand, the acupressure roller 6 is constructed as shown in FIGS. 6 and 7.

That is, the hemispherical protrusion 3 is formed on the outer peripheral surface of the base 36, which is formed into a substantially cylindrical shape from an elastic material such as rubber or synthetic resin.
7 are provided protrudingly, and the base 36 corresponding to these protrusions 37 has a space 38 that penetrates in the axial direction.
... is drilled.

Therefore, when a load is applied to the protrusion 37, the space 38 corresponding to the protrusion 37 is compressed and deformed, so that the protrusion 37 is elastically displaced in the axial direction of the base 36. .

Further, a mounting hole 40 having key grooves 39 and 39 is bored in the center of the base 36, and the above-mentioned roller shaft 7 is fitted into this mounting hole 40, and the acupressure roller 6 is always attached to the roller by a key (not shown). It is fixed to the shaft 7.

Next, the effect will be explained.

First, with the control bar 24 in a curved state, the timer 33
is activated, the drive source 12 is driven, and the support frame 3 is made to travel.

Now, if the drive pulley 13 of the drive source 12 rotates clockwise and the support frame 3 runs in the direction of the drive source 12, the support body 4 on the drive source 12 side of the support frame 3 24, the driving pin 27 protruding from the lower surface of the support 4 engages with the first retaining part 26b. Slide the control bar 24 in the running direction of the support frame 3.

Then, the actuating part 2 formed at one end of this control bar 24
8 turns on the micro switch 29 to change the rotation direction of the motor 10 of the drive source 12, so the drive pulley 13
rotates counterclockwise, causing the support frame 3 to travel in the opposite direction.

One support body 4 provided with the drive pin 27 of this support frame 3 is connected to the third engagement portion 26C of the control bar 24.
When the drive pin 27 comes to a position corresponding to
Slide it in the direction of travel.

Therefore, the actuating portion 28 of the control bar 24 moves away from the microswitch 29 and turns this microswitch 29 OFF.
Since the rotation direction of the motor 10 is changed again, the support frame 3 runs in the opposite direction.

In this way, the support frame 3 is configured such that the driving pin 27 protruding from the lower surface of one of the supports 4 engages with the first retaining portion 26 a and the third retaining portion 26 C of the control bar 24 . Since the main body 1 reciprocates over almost the entire length in the longitudinal direction, the entire body of the user lying on the fabric 1a is supported by the roller shafts 7, 4 held by the supports 4, 4. Pine surge is performed by the acupressure roller 6 of 7.

In addition, if the travel range of the support frame 3 is to be narrowed, that is, if the user wants to receive the pine surge in only one part of the body, the switching arm 32 of the switching mechanism 31 is rotated counterclockwise, and the operating rod 33 is rotated counterclockwise. When the control bar '24 is slid in the direction of the arrow, the control bar '24 connected to the operating rod 33 is elastically deformed from its curved state to a substantially straight line.

Then, the drive pin 27 protruding from the lower surface of one of the supports 4 of the support frame 3 engages the second retaining portion 2 of the control bar 24.
5b, the support frame 3 is positioned within the range where the drive pin 27 engages with the first retaining portion 26a and the second retaining portion 26b or the second retaining portion 26b. Joint part 2
6b and the third engaging portion 26C.

Therefore, the user only applies the acupressure roller 6 to one part of the body.
You can receive Pine Surge caused by...

Moreover, when the support frame 3 is reciprocated along almost the entire length of the main body 1 in the longitudinal direction, the support frame 3 is Displaced to.

That is, as shown in FIG. 5, the acupressure rollers 6 are displaced in the vertical direction in accordance with the uneven shape of the back surface of the user lying on the cloth 1a.

Therefore, since the acupressure rollers 6 move while pressing against the user's entire face with a substantially uniform force, the user's entire body can be massaged well.

By the way, as shown in FIGS. 6 and 7, the acupressure roller 6 has a hemispherical protrusion 37 protruding from its outer peripheral surface and a base 36 corresponding to the protrusion 37.
A space 38 is bored through the shaft in the axial direction.

Therefore, when the acupressure roller 6 that rotates together with the roller shaft 7 presses the user with its protrusion 37, the space 38 at the position corresponding to the protrusion 37 is compressed by the pressing force.

Therefore, since the protrusion 37 is elastically displaced toward the center of the acupressure roller 6, the protrusion 37 massages the user with an appropriate pressing force that is neither too strong nor too weak.

Note that the present invention is not limited to the above-mentioned embodiment, and for example, the acupressure device according to the present invention may be of a chair type in addition to the bed-type one mentioned in the above-mentioned embodiment.

As described above, the present invention provides an acupressure roller that is freely movable within the main body, has a protrusion formed on the outer circumferential surface, and a space that corresponds to the protrusion and is bored through it in the axial direction. Since the protrusion is made of an elastic material, when the protrusion presses the user, the space corresponding to the protrusion is compressed and deformed, so that the protrusion is elastically displaced.

Therefore, since the elastically displacing protrusion presses the user with a moderate pressing force, there is a great practical advantage in that the masturbation effect can be improved.
