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 an acupressure roller movably disposed inside the main body, which has an open top surface and a sheet stretched over the opening surface, and the acupressure roller is driven back and forth by a drive source. , the human body lying on the sheet is subjected to pine surgery.

By the way, in the acupressure device having such a configuration, a good acupressure effect cannot be obtained unless the acupressure roller running inside the main body strongly presses the body of the user lying on the seat. Therefore, a stretchable fabric or the like is used as a sheet stretched over the opening surface of the main body, and when the user lies down on the seat, the user's body deforms the sheet and falls sufficiently into the main body. In this way, the pressure applied to the human body by the acupressure roller is increased.

However, if the pressing force of the acupressure roller is increased in this way, a large load may be applied to the seat when the user lies down on the seat, or the user's body may move up and down along with the seat as the acupressure roller runs. If the device sways in any direction, the user's body may hit the hard inner bottom surface of the main body or the wire that is driven by the drive source for running the acupressure roller stretched inside the main body through the seat. Therefore, there were problems such as causing discomfort to the user and causing the seat to be damaged early due to rubbing against the wire.

This idea was made based on the above circumstances,
The purpose of this is to provide a protective material on the inner bottom surface of the main body so that even if the user's body hits the inner bottom surface of the main body through the seat, it will not cause discomfort to the user or the seat will To provide an acupressure device which is prevented from being damaged early.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, 1 is a frame 1 whose top surface is open and a sheet 1a made of stretchable fabric or the like is stretched over this open surface.
It is a box-shaped main body with a bottom made by joining b. A pair of rails 2, 2 are laid in parallel in the main body 1 along the longitudinal direction of the main body 1, and a support frame 3 is provided on the rails 2, 2 so as to be freely movable. This support frame 3 connects both ends of a pair of supports 4, 4 spaced apart in parallel with band-shaped elastic plates 5, 5, and a plurality of acupressure rollers 6 are rotatably attached to the supports 4, 4. The provided roller shafts 7, 7 are rotatably supported. Furthermore, wheels 9 that are in contact with the rails 2, 2 are provided on both sides of the supports 4, 4.

Further, 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 a drive pulley 13 is connected to the drive source 12.
The output shaft 14 fitted with the output shaft 14 projects horizontally.
Further, a driven pulley 15 is provided at the other end of the main body 1 with its axis being vertical.
A wire 16 is stretched between the drive pulley 13 and the drive pulley 13. That is, the wire 16 has a middle portion wound around the drive pulley 13 and the driven pulley 15, and both end portions are located within the support frame 3. Pins 18 and 18 having flanges 17 and 17 are fixed to both ends of this wire 16, respectively, and these pins 18 and 18 are connected via a spring 19. Each of the pins 18, 18 has a first interlocking bar 20 and a second interlocking bar 2 made of hard steel wire.
1 is formed at one end of the winding portions 20a, 21.
A is fitted. These interlocking bars 20, 21
are each guided in a direction opposite to the spring 19, and the other end portions are slidably supported by receiving portions 22, 22 protruding from the lower surfaces of the supports 4, 4 of the support frame 3. Receiving part 2
The ends protruding from 2 and 22 are bent into an L shape,
The interlocking bars 20, 21 are designed not to come off from the receiving parts 22, 22. Furthermore, 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, when the drive source 12 is actuated and the drive pulley 13 causes the wire 16 to run in the direction indicated by the arrow in FIG.
is pulled and runs, and when the wire 16 runs in the opposite direction, the support frame 3 is pulled and runs by the second interlocking bar 21. Further, at this time, the elongation of the wire 16 is absorbed by the restoring force of the spring 19 interposed in the wire 16, and the contact state between the wire 16 and the drive pulley 13 is maintained constant, so that the support frame 3 can move. becomes smooth.

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, that is, the acupressure rollers 6, which run on the rails 2, 2, are displaced upward by the convex portions 2a. 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... are adapted to the acupressure rollers 6... according to the uneven shape of the back surface of the human body. It is provided at a portion corresponding to the neck and foot of the human body so that it can be pressed with uniform force.

Further, a control bar 24 is slidably supported at both ends by receiving portions 25, 25 along the longitudinal direction of the main body 1 on one inner surface of the main body 1.
The control bar 24 is made of hard steel wire, and has first to third engaging portions 26a, 26b, and 26c bent in the longitudinal direction and at both ends so as to protrude in the horizontal direction. These engaging parts 26a, 2
6b and 26c are 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 moves.
It is adapted to slide by engaging with a driving pin 27 protruding from the lower surface of the holder as shown in FIG.
One end of the control bar 24 located on the driving source 12 side forms an actuating portion 28 bent into a hairpin shape.
Opposite this operating section 28 is a micro switch 29.
is installed. Therefore, the control bar 2
4 slides, the operating portion 28 turns on and off the micro switch 29. This micro switch 29 is electrically connected to the drive source 12, and is turned ON.
-The motor 10 of the drive source 12 is turned off by the OFF operation.
It is designed to rotate forward and backward.

On the other hand, an operation box 30 is provided on the outer surface of one side of the main body 1, and this operation box 30 is provided with a switching mechanism 31. This switching mechanism 31
is the switching arm 3 pivotally supported on the operation box 30.
2 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 switching arm 32 is rotated clockwise as shown by the arrow in FIG. The bar 24 is curved and deformed as shown by the chain line in the figure. Then, when the control bar 24 is curved and deformed,
Among the three engaging parts, the central engaging part 26b is connected to the main body 1.
Since the engagement portion 26b is largely displaced toward the inner surface of one side, one support member 4 of the support frame 3 is attached to the engaging portion 26b.
The drive pin 27 protruding from the lower surface is no longer engaged. Furthermore, the operation box 30
A timer 33 is provided 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 within the main body 1 so as to be located at both ends of the rails 2, 2. Further, on the inner bottom surface of the main body 1, an elastic protective material 35 made of a semi-hard foamed elastic material is stuck to the inner bottom surface of the main body 1, sandwiching the wire 16 stretched so as to extend along the inner bottom surface, and which is thicker than the height of the wire 16. has been done. Therefore, when the sheet 1a is bent, the sheet 1a comes into contact with the elastic protective material 35.

Next, the effect will be explained. First, the control bar 24 is bent, the timer 33 is activated, and the drive source 12 is driven to cause the support frame 3 to travel. Now, the drive pulley 13 of the drive source 12
When the support frame 3 rotates clockwise and the support frame 3 moves in the direction of the drive source 12, the support body 4 on the drive source 12 side of the support frame 3 engages with the first engaging portion 26a of the control bar 24. When the vehicle travels to the corresponding position, the drive pin 27 protruding from the lower surface of the support body 4 engages with the first engagement portion 26a, and slides the control bar 24 in the running direction of the support frame 3. let Then, the actuating part 28 formed at one end of the control bar 24 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 and supports it. Move frame 3 in the opposite direction. When one of the supports 4 on which the drive pin 27 of the support frame 3 is provided comes to a position corresponding to the third engagement part 26c of the control bar 24, the drive pin 27 is moved to the third engagement part 26c. 26c to slide the control bar 24 in the running direction of the support frame 3. Therefore, the above control bar 2
Since the actuating part 28 of No. 4 moves away from the micro switch 29 and turns this micro switch 29 OFF,
The rotation direction of the motor 10 is changed again, and the support frame 3 runs in the opposite direction.

In this manner, the support frame 3 has a drive pin 27 protruding from the lower surface of one of the supports 4 that connects the first engagement portion 26a of the control bar 24 and the third engagement portion 26 of the control bar 24.
Since it travels back and forth over the distance that it engages with c, that is, almost the entire length in the longitudinal direction of the main body 1,
The entire body of the user lying on the seat 1a is massaged by the acupressure rollers 6 of the roller shafts 7, 7 held by the supports 4, 4.

In addition, when it is desired to narrow the traveling range of the support frame 3, that is, when the user wants to receive the pine surge on only one part of the body, the switching arm 32 of the switching mechanism 31 is rotated counterclockwise, and the operating rod 3 is rotated counterclockwise.
3 in the direction of the arrow, this operating rod 3
The control bar 24 connected to the control bar 3 is elastically deformed from the curved state to a substantially linear shape. Then, the drive pin 27 protruding from the lower surface of one of the supports 4 of the support frame 3 also comes to engage with the second engaging portion 25b of the control bar 24, so that the support frame 3
The driving pin 27 reciprocates in the range where it engages with the first engaging part 26a and the second engaging part 26b or the range where it engages with the second engaging part 26b and the third engaging part 26c. Run. Therefore, the user can receive the pine surge by the acupressure rollers 6 only on one part of the body.

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 convex portions 2a provided protrudingly from the seats 2, 2. 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, the acupressure rollers 6 move while pressing against the entire back surface of the user with a substantially uniform force, so that the user's whole body can be massaged well.

On the other hand, when the user M lies down on the seat 1a, the seat 1a may be affected by applying a large load to the seat 1a or by the support frame 3 moving back and forth.
When the user M who is lying on his side shakes in the vertical direction, the seat 1a is greatly deformed and the user M falls into the main body 1. At this time, the user M falls into the main body 1 through the seat 1a. Elastic protective material 3 made of semi-hard foamed elastic material provided on the inner bottom surface
It falls under 5. Therefore, the user M uses the elastic protective material 3
5. The soft feel means you won't feel any discomfort. Moreover, since the elastic protective material 35 has a thickness such that its upper surface is higher than the height of the wire 16, the bent sheet 1a inside the main body 1 is
There is no chance that it will be damaged by being rubbed by 6.

As described above, the present invention provides an acupressure device in which an acupressure roller is movably provided in a main body having an open top surface and a sheet stretched over the opening surface, and the acupressure roller is reciprocated by a drive source. Since an elastic protective material is provided on the inner bottom surface of the main body, the user lying on the seat may sway vertically due to the user's load or the movement of the acupressure roller, causing the seat to slide into the main body. When deflected to a large extent, this sheet hits the elastic protection material. Therefore, the user who lies down on the seat will not feel discomfort due to the softness of the elastic protective material, and the seat will not rub against wires etc. that are run by a drive source provided within the main body. This has the practical effect of preventing premature damage due to
