Description

[Detailed Description of the Invention] The present invention relates to an acupressure device having a pine surge function.

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. That is, the acupressure roller has hemispherical protrusions protruding from its outer peripheral surface, and these protrusions press pressure points on the human body.

By the way, according to the acupressure device having the above configuration, the pair of acupressure rollers press pressure points on both sides of the back vertebrae of the human body with the protrusions provided on the outer peripheral surface of the pair of acupressure rollers.
Although the acupressure roller can provide a so-called acupressure effect to the user, the acupressure roller only presses a small portion on both sides of the human body's dorsal vertebrae with its protrusions. Therefore, there is no need to press pressure points on the outer parts of both sides of the back vertebrae or to massage the muscles of the back of the human body over a wide range.

This idea was made based on the above circumstances,
The purpose is to provide an acupressure device that can effectively massage a wide range of the back of the human body.

Also, inside the main body 1, a band-shaped actuating plate 25 is connected at one end to one longitudinal end surface of the main body 1 by a connecting rod 23 and at the other end to the other end surface of the main body 1 via a spring 24.
is installed over almost the entire length of the main body 1 in the longitudinal direction. The actuation plate 25 is inserted between the first and second supports 4a, 4b of the support frame 3 and the roller shafts 6, 6, and is inserted between the first support 4a and the roller shaft 6. The positioned portion is a pair of first sleeves 10, 10 fitted onto the roller shaft 6.
It is held in place by flanges 26, 26 formed on the sides. Further, as shown in FIG. 5, the first support body 4a is provided with the pair of first sleeves 10, 10.
A holder 27 is provided to maintain the state in which the actuating plate 25 is held between the flanges 26, 26. The width of the actuating plate 25 changes along its longitudinal direction. That is, when the user holds the first support 4
When the user lies down on the main body 1 with the head positioned on the a side, the part corresponding to the user's neck is the narrowest, and the width gradually increases from the neck to the waist. Therefore, when the support frame 3 runs inside the main body 1, the first support body 4
A pair of first acupressure rollers 11, 11 are disposed along with the first sleeves 10, 10 against the restoring force of springs 16, 16 in accordance with the width dimension of the actuating plate 25. 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 a drive pulley 34 is connected to the drive source 30 from this drive source 30.
The output shaft 35 fitted with the output shaft 35 projects horizontally.
Further, a driven pulley 36 is provided at the other end of the main body 1 with its axis being vertical.
A wire 37 is stretched between the drive pulley 34 and the drive pulley 34 . That is, the wire 37 has a middle portion wound around the drive pulley 34 and the driven pulley 36, and both end portions are located within the support frame 3. Pins 39, 39 having flanges 38, 38 are fixed to both ends of this wire 37,
These pins 39, 39 are connected via a spring 40. A first interlocking bar 41 and a second interlocking bar 42 made of hard steel wire are slidably fitted into each of the pins 39, 39 with winding portions 41a, 42a formed at one end thereof. These interlocking bars 41 and 42 are each guided in a direction facing the spring 40, and the other ends thereof are provided at receiving portions 43 and 43 protruding from the lower surfaces of the first and second supports 4a and 4b of the support frame 3, respectively. The ends protruding from the receiving parts 43, 43 are bent into an L-shape to prevent the interlocking bars 41, 42 from coming off the receiving parts 43, 43. ing. 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, when the drive source 33 is activated and the drive pulley 34 causes the wire 37 to travel in the direction indicated by the arrow in FIG. 6, the support frame 3 is pulled and travels by the first interlocking bar 41. Further, when the wire 37 runs in the opposite direction, the support frame 3 is pulled by the second interlocking bar 42 and runs. Therefore, the tension of the wire 37 is not applied directly to the spring 40. Also,
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 contact state between the wire 37 and the drive pulley 34 is maintained constant, so that the support frame 3 can run smoothly. becomes.

On the other hand, the rails 2, 2 have a plurality of convex portions 2a...
are provided at corresponding positions, and the support frame 3 runs on the rails 2, 2 by the convex portions 2a...
In other words, the first and second supports 4a and 4b are moved upward. The above-mentioned convex portions 2a... are
As shown in FIG. 8, 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 apply uniform pressure according to the uneven shape of the back of the human body. It is located in areas corresponding to the neck and feet of the human body.

Further, a control bar 45 is slidably supported at both ends by receiving portions 46, 46 along the longitudinal direction of the main body 1 on one inner surface of the main body 1.
The control bar 45 is made of hard steel wire, and has first to third engaging portions 47a, 47b, and 47c bent in the longitudinal direction and at both ends so as to protrude in the horizontal direction. These engaging portions 47a,
47b, 47c are attached to the lower surface of the second support body 4b of the support frame 3, that is, the support body 4b located on the drive source 33 side, as shown in FIG. It is adapted to slide by engaging with a protruding drive pin 48. One end of the control bar 45 located on the driving source 33 side forms an actuating part 49 bent into a hairpin shape, and a micro switch 50 is disposed opposite to this actuating part 49. Therefore, when the control bar 45 slides, its actuating portion 49 turns the micro switch 50 on and off. This micro switch 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 this operation box 51 is provided with a switching mechanism 52. This switching mechanism 52
is a switching arm 5 pivotally supported on an operation box 51.
3 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 switching arm 53 is rotated clockwise as shown by the arrow in FIG. The bar 45 is curved and deformed as shown by the chain line in the figure. Then, when the control bar 45 is curved and deformed,
Among the three engaging parts, the central engaging part 47b is connected to the main body 1.
Since the engagement portion 47b is largely displaced toward the inner surface of one side, the second support 4 of the support frame 3 is attached to the engaging portion 47b.
b The drive pin 48 protruding from the lower surface does not engage. Furthermore, operation box 5
1 is provided with a timer 55 for setting the operating time of the drive source 12.

In addition, stoppers 56 for preventing the support frame 3 from coming off from the rails 2, 2 are provided inside the main body 1 so as to be located at both ends of the rails 2, 2, and on the inner bottom surface of the main body 1. is elastic material 5
7 is pasted, and this elastic material 57 makes the fabric 1a
This prevents the user's body from directly hitting the wire 37 etc. when it bends.

Next, the effect will be explained. First, the control bar 35 is bent, the timer 55 is activated, and the drive source 33 is driven to cause the support frame 3 to travel. Now, the drive pulley 34 of the drive source 33
When the support frame 3 rotates clockwise and moves in the direction of the drive source 33, the second support body 4b of the support frame 3 on the drive source 33 side engages with the first engagement portion of the control bar 45. When traveling to a position corresponding to 47a, the first support 4b
A drive pin 48 protruding from the lower surface of the control bar 45 engages with the first engaging portion 47b to slide the control bar 45 in the running direction of the support frame 3. Then, the actuator 49 formed at one end of the control bar 45 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 and supports the drive pulley 34. Move frame 3 in the opposite direction. When the second support body 4b of the support frame 3, on which the drive pin 48 is provided, comes to a position corresponding to the third engagement portion 47c of the control bar 45, the drive pin 48 is moved to the third position.
The control bar 45 is slid in the running direction of the support frame 3 by engaging with the engaging portion 47c of the control bar 45 . Therefore, the actuating portion 49 of the control bar 45 is separated from the micro switch 50, and the micro switch 50
is turned off, the rotational direction of the motor 31 is changed again and the support frame 3 runs in the opposite direction.

In this way, in the support frame 3, the drive pin 48 protruding from the lower surface of the second support body 4b is connected to the first engagement portion 47a of the control bar 45 and the third engagement portion 4 of the control bar 45.
7c, that is, almost the entire length in the longitudinal direction of the main body 1, the entire body of the user lying on the fabric 1a is supported by the roller shafts 4, 4. The acupressure rollers 11, 19 and pine surge rollers 14, 20 of 7 and 7 perform acupressure and pine surge.

In addition, when the travel range of the support frame 3 is desired to be narrowed, that is, when the user wants to receive the pine surge on only one part of the body, the switching arm 53 of the switching mechanism 52 is rotated counterclockwise, and the operating rod 5 is rotated counterclockwise.
4 in the direction of the arrow, this operating rod 5
4 is elastically deformed from a curved state to a substantially straight line. Then, the drive pin 48 protruding from the lower surface of the second support body 4b of the support frame 3 engages with the second engagement portion 46b of the control bar 45.
Since it also engages with the support frame 3
is the range in which the drive pin 48 engages with the first engaging portion 47a and the second engaging portion 47b or the second engaging portion
It travels back and forth within the range where it engages with the engaging portion 47b and the third engaging portion 47c. Therefore, the user
Only one part of the body can receive acupressure and pine surge from the shiatsu rollers 11, 19 and pine surge rollers 14, 20.

Further, when the support frame 3 is reciprocated over almost the entire length in the longitudinal direction of the main body 1, the support frame 3 is displaced in the vertical direction by the protrusions 2a provided on the rails 2, 2. 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
Since the pine surge rollers 14 and 20 move while pressing against the user's entire back surface with a substantially uniform force, the user receives good acupressure and pine surge motion over the entire body.

By the way, according to the above configuration, the support frame 3
When the user moves into the main body 1, the first support body 4a reciprocates from the user's neck to the waist,
A pair of first acupressure rollers 11, 11 provided at the center of the roller shaft 6 slide in the axial direction of the roller shaft 6 according to changes in the width dimension of the actuating plate 25, and the protrusions 12... At the same time as pressing the pressure points on both sides of the spine, the first acupressure roller 11,
Band-shaped protrusions 15 of a pair of first pine surge rollers 14, 14 located outside the body massage the muscles and ligaments of the human body from the shoulders to the waist. In addition, the second support body 4b reciprocates in a portion extending from the user's waist to the legs, and a pair of second acupressure rollers 1 provided on the roller shaft 6 are connected to the second support body 4b.
9 and 19 press pressure points on both legs, and at the same time, a pair of second pine surge rollers 20 and 20 massage the entire muscles of both legs. That is, the user presses the first and second acupressure rollers 11 and 19 and the protrusions 12 and 21 of the first and second pine surge rollers 14 and 20.
The whole body is massaged by 15 and 22. Moreover, the protrusions 15 of the pine surge rollers 14, 20,
Since the width dimension of 20 is larger than that of the protrusions 12 and 21 of the acupressure rollers 11 and 19, the area that contacts the user's body is equal to that of the protrusions 1 of the acupressure rollers 11 and 19.
It becomes larger than 2.21. Therefore, the user's body is closer to the projections 14, 20 of the pine surge rollers 14, 20 than to the projections 12, 21 of the acupressure rollers 11, 19.
Shiatsu roller 1
The small protrusions 12 and 21 of 1 and 19 press strongly and massage the entire body without feeling any pain.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and it goes without saying 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.

Further, the means for driving the support frame may be other wire chains, screw shafts, or the like, and is not limited in any way.

Furthermore, as shown in FIG.
and second supports 4b, 4b may be provided. With such a configuration, the number of acupressure rollers and pine surge rollers increases. Therefore, the acupressure and pine surge effects caused by one reciprocation of the support frame 3 can be combined with the above-mentioned one. It can be increased compared to the example.

As described above, according to the present invention, a pair of acupressure rollers each having a substantially hemispherical first protrusion formed on the outer peripheral surface are provided on the roller shaft, and the width dimension is larger than that of the acupressure roller on the outside of the acupressure roller. A pair of pine surge rollers each having a plurality of band-shaped second protrusions formed along the axial direction on the outer circumferential surface thereof were provided. Therefore, not only is the user's entire body massaged by the first and second protrusions, but the user's body is also massaged by the band-shaped second protrusion rather than by the roughly hemispherical first protrusion. Since the contact area is larger, the entire body is effectively massaged without feeling any pain due to strong pressure from the small first protrusion.
