Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a pine surge device that allows a user to receive pine surgery over the entire body.

(Prior Art) Generally, a pine tress type pine surgery device, which allows a user to receive pine surgery over the entire body, has a flat base. A guide rail is laid on the upper surface of the base body along its longitudinal direction, and a holder holding a pine surge roller is movably provided on the guide rail. A drive device is disposed at one end in the longitudinal direction of the base,
The pine surge roller is driven to travel by this drive device. The upper surface side of the base is covered with an exterior material. When the user receives a pine surge, a pillow is placed on the upper surface of the exterior material on the other longitudinal end side of the base, and the user rests his or her head on this pillow and lies face up on the exterior surface. and,
By driving the above pine surge roller,
The entire back area receives pine surge.

By the way, in the pine surge device having such a structure, the above-mentioned exterior fabric is stretched in a slack state in order to properly transmit the pressing force from the pine surge roller to the user's body. Therefore, if a pillow is simply placed on the top surface of the exterior material, the tension of the exterior material will fluctuate as the pine surge roller runs, and the exterior material will become wavy. As a result, the pillow placed on the exterior ground also displaces in the vertical direction, making it impossible to support the user's head at a constant height.
There were cases where the user was unable to receive the pine surge for pleasure.

(Problem to be solved by the invention) In this way, conventionally, when a user received a pine surge, the pillow on which the user rested was simply placed on the exterior ground, and as the pine surge roller traveled, the pillow was simply placed on the exterior ground. When the tension of the exterior material fluctuates, the pillow also moves up and down accordingly, making the state of support for the head unstable.

This idea was made based on the above circumstances, and its purpose is to prevent the pillows provided on the exterior ground from moving up and down even if the exterior ground is undulated by the pine surge roller. The goal is to provide equipment.

[Structure of the device] (Means and effects for solving the problem) In order to solve the above problem, this device includes a flat base and a pine surge provided movably along the longitudinal direction of the upper surface of the base. a roller, a drive device for driving the pine surge roller provided on one longitudinal end of the base, a pillow base formed of a rigid material and provided on the upper surface of the other longitudinal end of the base; The device includes an exterior fabric covering the upper surface of the base, and a pillow provided on the upper surface of the exterior fabric at a position facing the pillow base.

With this configuration, the pillow is supported by the pillow base via the exterior material, so it does not move up and down due to fluctuations in the tension of the exterior material.

The engaging shafts 212 provided at both ends thereof face each other.
Therefore, by rotating the handle member 210 and engaging it with the engagement shaft 212, the base body 2 can be held in a folded state, and the handle member 2
The base body 2 can be carried by holding the handle 10.

Next, a case where the pine surgery device 1 having the above structure is used will be explained. First, when the user lies face up on the massage device 1, the user operates a switch box (not shown) to activate the drive source 64 of the drive device 56. When 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 The second driving pulley 76 and the third driving pulley 80 rotate in opposite directions. Therefore, the pair of belts 86
are wound around the first driving pulley 70 and the fourth driving pulley 84, respectively, and are sent out from the second driving pulley 76 and the third driving pulley 80 in accordance with the winding. , the portion of the belt 86 inserted into the upper passage 21 of the guide rail 10 runs in the direction shown by arrow Z in FIG.

5 will perform pine surgery on the back of the user.

On the other hand, when the output shaft 66 rotates in the direction of arrow X,
The first mounting shaft 72 rotates in the direction of arrow Y, and the plate-shaped body 136 of the control device 134 is interlocked with the rotation. When the plate-like body 136 rotates in the direction of arrow Y, the shaft-like body 156 that is engaged with the first and second guide grooves 140 and 142 of the plate-like body 136 moves relatively along the guide grooves. , the frame 152 rotates in the direction indicated by arrow T in FIG. Then, as the disc-shaped body 136 rotates, one shaft-shaped body 156 engaged with the first guide groove 140 is moved to the first stepped portion 144.
When the shaft member 156 is displaced in the direction of protruding from the first guide groove 140, one leaf spring 154 to which the shaft member 156 is attached is elastically deformed as shown by the chain line in FIG. 160
Activate. Then, the rotation direction of the output shaft 66 of the drive source 64 is changed by the signal from the first limit switch 160, so that the belt 86
The traveling direction of the portion inserted into the upper passage 20 is opposite to the direction of arrow Z. Therefore, since the pair of holders 90 are linked to the running of the belt 86, the direction in which the user receives the pine surge is also reversed. Also, at this time, the plate-shaped body 136 rotates in the opposite direction to that previously, that is, in the opposite direction to the arrow Y, so the frame 152 rotates in the opposite direction to the arrow T. Then, when the other shaft-like body 156 engaged with the second guide groove 142 is displaced by the second step portion 146, the other leaf spring 154 to which this shaft-like body 156 is attached is moved to the 28th position. As shown by the chain line in the figure, it is elastically deformed to operate the second limit switch 162. Then, the second limit switch 162
Since the rotation direction of the output shaft 66 of the drive source 64 is changed by the signal from the drive source 64, the running direction of the pair of holders 90 becomes the Z direction again.

By the way, the first pine surge roller 122
The pair of first collars 116 to which are attached have a tongue piece 130 and an engaging part 131 formed at one end of each other.
Rotates integrally by engagement with. In other words, the pair of first pine surge rollers 122 rotate without shifting the positions of the protrusions 124 formed on their outer peripheral surfaces in the circumferential direction. Therefore, the projections 124 of the pair of first pine surgery rollers 122 press pressure points on both sides of the user's spine at the same time, allowing the user to receive comfortable and highly effective pine surgery.

Further, the base body 2 is elastically supported by an elastic sheet 9 bonded to the lower surface side of the base body 2. Therefore, not only does the user feel good when lying on the base 2, but also the holder 9
Since the vibrations generated in the base body 2 by the running of the 0 are absorbed by the elastic sheet 9, the user can receive the pine surge in a good condition with less vibration.

Further, holders 90 are provided on both sides of the base 2 in the width direction.
The first and second pine surge rollers 12 held in
A side elastic member 170 having a height dimension higher than the support height of 2,123 is provided. Therefore, the upper sheet 1
If a user lying on 80 shifts his or her body too much in the width direction of the base 2 in order to adjust the position where the user hits the back surface of the first and second pine surge rollers 122, 123, the user's body will be moved by the side elastic member. Since it corresponds to 170, it prevents the body from shifting too far. In other words, the side elastic members 170 prevent the user from shifting his or her body too much and falling off the base 2.

Further, a pillow base 166 is provided at one end in the longitudinal direction of the base body 2, and a pillow 184 is detachably provided on the upper surface of the upper sheet 180 corresponding to the pillow base 166. Therefore, the pillow 184 is reliably held by the pillow base 166 without vertical movement, so the pillow 184 can firmly support the user's head. In other words, if the pillow 184 is simply placed on the upper sheet 180, when the tension of the upper sheet 180 changes due to the movement of the pine surge rollers 122 and 123, the pillow 184 will move in the vertical direction accordingly. However, since the pillow 184 is supported by the pillow base 166 via the upper sheet 184, it will not move up and down due to fluctuations in the tension of the upper sheet 184. Furthermore, since the upper surface of the pillow base 166 is formed into a curved surface 168 that is most concave at the center in the width direction, the user's head can be supported stably by this curved surface 168 as well.

By the way, when the pine surge device 1 is not in use, it can be folded into two from the longitudinal center portion of the base body 2, as shown in FIG.
That is, since the bendable first flexible portion 8 and second flexible portion 40 are formed in the longitudinal center portions of the base body 2 and the guide rail 10, respectively,
The base body 2 and the guide rail 10 can be folded into two together with the side elastic members 170 provided on the upper surface of the base body 2. Therefore, the length of the pine surge device 1 can be reduced to about half when not in use, making it convenient for storage. Also,
When the pine surge device 1 is folded, the handle member 210 provided on the first band 204 on one longitudinal end side of the base body 2 is connected to the engagement shaft 212 provided on the second band 206 provided on the other end side. When engaged, not only can the pine surge device 1 be held in a folded state, but also it can be easily carried by placing a hand on the handle member 210.

In this way, when folding the pine surge device 1, the holder 9 is placed at the first and second flexible parts 8, 40, which are the bent parts of the base 2 and the guide rail 10.
0 may be stuck. When the base body 2 and the guide rail 10 are bent in this state, the distance W 1 between the pair of mounting plates 119 fixed to the belt 86 becomes the distance W ₁ before bending as shown in FIG. 18, as shown in FIG. It is smaller than ₂ .
Therefore, the bottom portion of the wire 115, which was bent into a substantially triangular shape, is bent in accordance with the dimensional difference W ₂ −W ₁ , so that the wire 115 of the holder 90 is bent as shown in FIG. minutes 1st, 2nd
from the bent portions 8 and 40 in the direction of the arrow. Therefore, there is no possibility that the first and second flexible parts 8, 40 cannot be bent by the holder 90.

When bending the pine surge device 1, the drive device 56 may not be stopped and the pine surge device 1 may be bent while the holder 90 is running. In that case, the wire rod 194 of the switch mechanism 190 is deformed from the state shown by the 29th solid line at the spring portion 192 as shown by the chain line, and the end connected to the lever 196 slides in the direction of the arrow. As a result, the lever 196 rotates away from the actuator 198a of the cutoff switch 198 and turns off the cutoff switch 198, so that the drive device 56
The power supply to the holding body 90 is cut off, and the movement of the holding body 90 is stopped. Further, the switch mechanism 190 operates not only when the pine surge device 1 is folded, but also when the pine surge device 1 is installed in a curved state beyond a predetermined degree, and cuts off the power supply to the drive device 56. Therefore, when the guide rail 10 is curved and the running resistance of the holder 90 is greater than in a normal state, the holder 90 is not allowed to run, so the holder 90 is not forced to run and is damaged. This prevents the drive device 56 from being damaged due to overload.

In addition, by repeating the bending and unfolding of the base body 2 when in use and when not in use, the first flexible portion 8
These areas are prone to early damage. However, since the upper surface of the base body 2 at the location of the first flexible portion 8 is reinforced by bonding and fixing a reinforcing sheet 11, the location of the first flexible portion 8 is quickly strengthened by this reinforcing sheet 11. It can prevent damage.

[Effects of the invention] As described above, in this invention, a pillow base is provided on the upper surface of the longitudinal end portion of the base, and a pillow is provided on the upper surface of the exterior material facing the pillow base. Therefore, since the pillow is supported by the pillow base, even if the tension of the exterior material fluctuates as the pine surge roller runs, the pillow moves up and down to support the user's head. The situation never becomes unstable.
