Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an acupressure device that applies acupressure to a human body by reciprocating and driving an acupressure roller.

In general, this type of acupressure device has a main body with an open top surface and a cloth stretched over the opening surface, and a support frame that is movably disposed inside the main body, and a roller shaft on which an acupressure roller is installed on this support frame. It becomes.

By moving the support frame back and forth using a drive source, the human body lying on the cloth is pressed by the acupressure roller.

Recently, in order to enhance the acupressure effect of the acupressure roller, it has been considered to provide a protrusion on the outer peripheral surface of the acupressure roller so that the protrusion strongly presses the part of the human body called the hip.

Since the acupuncture points of the human body are located on both sides of the spine on the back of the human body, a pair of acupressure rollers provided on a roller shaft may be made to run convexly on both sides of the spine.

However, since the human spine gradually becomes thicker from the cervical vertebrae to the lumbar vertebrae, the distance between the pressure points on both sides of the spine also increases as the thickness changes.

Therefore, even if a pair of acupressure rollers are simply installed on the roller shaft at a predetermined interval and run inside the main body, there will be a portion where the acupressure rollers will come off from the pressure points on both sides of the spine on the back of the human body, resulting in insufficient acupressure effects. The problem arises that it cannot be obtained.

The present invention has been made based on the above circumstances, and its purpose is to allow a pair of acupressure rollers provided on a roller shaft to travel inside the main body while changing the interval according to changes in the thickness of the human spine. To provide an acupressure device that can reliably press acupuncture points located on both sides of the spine.

The protrusions 12 of the second pine surge rollers 20, 20 are provided at a wider interval than the protrusions 12 of the second pine surge roller 20, and the protrusions 22 of the second pine surge roller 20, 20 are provided with a narrower interval.

Further, inside the main body 1, there is a band-shaped actuating plate 25 whose one end is connected to one longitudinal end surface of the main body 1 by a connecting rod 23 and the other end is connected to the other end surface of the main body 1 via a spring 24. The direction is the tail, which is constructed over almost the entire length.

This actuating plate 25 is inserted between the eleventh second supports 4a, 4b of the support frame 3 and the roller shafts 6, 6, and
The portion inserted between the support body 4a and the roller shaft 6 is held between flanges 26.26 formed on a pair of first sleeves 10.10 fitted over the roller shaft 6. .

Further, on the first support body 4a, as shown in FIG.
is provided.

The width of the actuation plate 25 changes along its longitudinal direction.

That is, when a user lies down on the main body 1 with his head positioned on the side of the first support 4a, the part corresponding to the user's neck is the narrowest, and the width gradually increases from the neck to the waist. It is designed to be wide.

Note that the portion of the actuating plate 25 corresponding to the user's head gradually becomes thicker from the portion corresponding to the neck.

Further, a drive source 30 in which a motor 28 and a transmission 29 are integrated is disposed at one end in the longitudinal direction within the main body 1, and an output shaft 35 on which a drive pulley 34 is fitted is connected from the drive source 30.
is projected horizontally.

A driven pulley 36 is provided at the other end of the main body 1 with its axis perpendicular, and a wire 37 is stretched between the driven pulley 36 and the driving pulley 34.

That is, this wire 37 connects the middle part to the drive pulley 3.
4 and a driven pulley 36, and both ends thereof are located within the support frame 3.

Pins 39.39 having flanges 38.38 are fixed to both ends of this wire 37, and these pins 39.3

Each of these interlocking bars 41, 42 is guided in a direction opposite to the spring 40, and the other end is connected to the support frame 3.
The receivers protruding from the lower surfaces of the eleventh second supports 4a and 4b are slidably supported by the portions 43.43, and the ends of the receivers protruding from the portions 43.43 are L-shaped. The interlocking bars 41 and 42 are bent to prevent them from coming off the receivers 43 and 43.

Furthermore, the contact length of the wire 37 with the drive pulley 34 is increased by an auxiliary pulley 44 disposed near the drive pulley 34.

Therefore, the drive source 33 operates and the drive pulley 34
When the wire 37 runs in the direction shown by the arrow in FIG. The support frame 3 is pulled and runs.

Therefore, the tension of the wire 37 is not applied directly to the spring 40.

Further, at this time, the elongation of the wire 37 is absorbed by the restoring force of the spring 40 interposed in the wire 37, and the wire 37 is
Since the contact state between the drive pulley 7 and the drive pulley 34 is maintained constant, the support frame 3 can run smoothly.

On the other hand, the rails 2, 2 are provided with a plurality of protrusions 2a... at corresponding positions, and the support frame 3, which runs on the rails 2, 2, is supported by the protrusions 2a...
, to displace the second supports 4a, 4b upward.

As shown in FIG. 8, the convex portions 2a... are formed when the user M lies down on the cloth 1a stretched over the opening surface of the main body 1.
The acupressure and pine surge rollers are provided at portions corresponding to the neck and feet of the human body so as to press against them with uniform force depending on the uneven shape of the back surface of the human body.

Further, a control bar 45 is supported on one inner surface of the main body 1 along the longitudinal direction of the main body 1 by support portions 46 and 46 so as to be slidable at both ends thereof.

This control bar 45 is made of hard steel wire, and has first to third engaging portions 47a, 47 at its longitudinal midway point and at both ends.
b and 47c are bent so as to protrude in the horizontal direction.

These engaging portions 47a. 47b and 47c are provided to protrude from the lower surface of the second support 4b of the support frame 3, that is, the support 4b located on the drive source 33 side, as shown in FIG. 7, as the support frame 3 travels. It engages with the driven pin 48 and slides.

One end of the control bar 45 located on the drive source 33 side forms an actuating part 49 bent into a hairpin shape.
A microswitch 50 is disposed facing the switch 9.

Therefore, when the control bar 45 slides, its operating portion 49 turns the microswitch 50 to 0N.
-It is designed to be turned off.

This microswitch 50 is electrically connected to the drive source 33, and this ON-OFF operation causes the motor 31 of the drive source 33 to rotate in forward and reverse directions.

On the other hand, an operation box 51 is provided on the outer surface of one side of the main body 1, and a switching mechanism 52 is provided on this operation box 51.

The switching mechanism 52 includes a switching arm 53 pivotally supported on the operation box 51 and an operating rod 54 having one end fixed to the switching arm 53 and the other end connected to the control bar 45. When the control bar 45 is rotated in the clockwise direction indicated by the arrow in FIG. 2, the control bar 45 is curved and deformed as indicated by the chain line in the figure.

Then, when the control bar 45 is curved and deformed, the central engaging part 47b of the three engaging parts is largely displaced toward the inner surface of one side of the main body 1. The drive pin 48 protruding from the lower surface of the second support body 4b is no longer engaged.

Further, the operation box 51 is provided with a timer 55 for setting the operating time of the drive source 12.

Further, stoppers 56 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 57 is attached to the inner bottom surface of the fabric 1a, and this elastic material 57 prevents the user's body from directly hitting the wire 37 etc. when the fabric 1a is bent.

Next, the effect will be explained.

First, with the control bar 35 in a curved state, the timer 55
is activated, the drive source 33 is driven, and the support frame 3 is made to travel.

Now, if the drive pulley 34 of the drive source 33 rotates clockwise and the support frame 3 travels in the direction of the drive source 33, then the second support 4b of the support frame 3 on the drive source 33 side is the first engaging portion 47a of the control bar 45
When the drive pin 48 protruding from the lower surface of the first support body 4b engages with the first engagement portion 47b, the control bar 45 is moved to a position corresponding to the support frame 3.
Slide it in the direction of travel.

Then, the actuating portion 4 formed at one end of this control bar 45
9 turns on the micro switch 50 to change the rotation direction of the motor 31 of the drive source 33, so the drive pulley 34
rotates counterclockwise, causing the support frame 3 to travel in the opposite direction.

The second support body 4b provided with the drive pin 48 of the support frame 3 is connected to the third engagement portion 47 of the control bar 45.
When the drive pin 48 reaches the position corresponding to c, the drive pin 48 engages with the third engagement 147c to move the control bar 45 to the support frame 3.
Slide it in the direction of travel.

Therefore, the actuating portion 49 of the control bar 45 moves away from the microswitch 50 and turns this microswitch 50 OFF.
Therefore, the rotational direction of the motor 31 is changed again and the support frame 3 runs in the opposite direction.

In this way, the support frame 3 has its second support 4b
A drive pin 48 protruding from the lower surface of the control bar 45
Since the body 1 travels reciprocatingly over the length of the engaging portion 47a and the third engaging portion 47c, that is, the longitudinal direction of the main body 1, the whole body of the user lying on the fabric 1a. Acupressure and pine surge are performed using the shiatsu roller IL19 of the roller shafts 7, 7 held by the supports 4, 4 and the pine surge rollers 14, 20.

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 53 of the switching mechanism 52 is rotated counterclockwise, and the operating rod 54 is rotated counterclockwise. When the control bar 45 is slid in the direction of the arrow, the control bar 45 connected to the operating rod 54 is elastically deformed from a curved state to a substantially linear shape.

Then, the drive pin 48 protruding from the lower surface of the second support body 4b of the support frame 3 also comes to engage with the second engagement portion 46b of the control bar 45, so that the support frame 3 , the range where the drive pin 48 engages with the first retaining portion 47a and the second engaging portion 47b or the second engaging portion 47
b and the third engaging portion 47c.

Therefore, the user only applies the acupressure roller to one part of the body.
1, 19 and pine surge rollers 14, 20.

Further, when the support frame 3 is reciprocated over almost the entire length of the main body 1 in the longitudinal direction, the support frame 3 is displaced in the vertical direction by the convex portions 2a .

That is, as shown in FIG. 8, 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, the acupressure rollers 11, 19 and the pine surge rollers 14, 20 move while pressing against the entire back surface of the user with a substantially uniform force, so that the user receives good acupressure and pine surge massage over the entire body.

By the way, when the support frame 3 runs inside the main body 1, the pair of first acupressure rollers 1 provided on the first support body 4a
1 and 11 are roller shafts 6 according to the width dimension of the actuating plate 25 which is installed on the main body 1 together with the first sleeve 10° 10.
slide in the axial direction.

That is, since the actuating plate 25 is thinnest at the part corresponding to the user's neck and gradually becomes wider from the neck to the waist, the pair of first acupressures can be adjusted according to the change in the width of the actuating plate 25. The support frame 3 travels while the opposing distance between the rollers 11, 11 changes.

Therefore, since the facing distance between the first acupressure rollers 11 and 11 changes in response to changes in the thickness of the spine of the human body,
A projection 12 protruding from a pair of acupressure rollers 11, 11...
・Reliably presses the pressure points on both sides of the spine from the neck to the lower back of the human body, resulting in a good acupressure effect.

Further, when the pair of first acupressure rollers 11, 11 slide together with the first sleeve 10.10 in a direction away from each other against the restoring force of the spring 16.16, the pair of first finger pressure rollers 10. 10°10 are these engaging parts 9, 9
are in an engaged state.

Therefore, the pair of first acupressure rollers 11.degree. 11 rotate together with these protrusions 12 in correspondence with each other and simultaneously press the tails on both sides of the spine, which also improves the acupressure effect.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and it is strongly believed that the acupressure device according to the present invention can be applied not only to the bed-type device mentioned in the above-mentioned embodiment but also to the chair-type device. be.

In addition, the means for driving the support frame may be a chain, a screw shaft, or the like instead of a wire, and this point is not limited in any way.

Furthermore, the present invention provides a support frame 3 as shown in FIG.
A pair of first supports 4a+4a and a pair of second supports 4b, 4b may be provided in each of the support frames 3 and 4b.With such a configuration, the number of acupressure rollers increases. The acupressure and pine surge effect due to reciprocation can be enhanced compared to the above embodiment.

As described above, in the present invention, a roller shaft is installed on a support frame that is reciprocated within the main body, a pair of acupressure rollers are rotatably and slidably held on this roller shaft, and the pair of acupressure rollers are held by a spring. A band-shaped actuating plate was provided on the main body along the running direction of the support frame so as to be partially held in the width direction by a pair of finger pressure rollers.

Therefore, if the width of the actuating plate is made to correspond to changes in the thickness of the human spine, the pair of acupressure rollers can be moved around the roller shaft in response to changes in the width of the actuating plate as the support frame moves. Since it slides in the axial direction, the pair of acupressure rollers can reliably press the acupuncture points on both sides of the spine, which has a great practical effect of increasing the acupressure effect.
