DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage device which receives a massage while lying upward on a moving massage roller.

[0002]

2. Description of the Related Art A massage device of this kind has a real
There is a mattress type shown in JP-A-20434. This massage device has a long flat base body, a pair of guide rails is laid on both sides in the width direction of the base body, and a driving device using a motor as a driving source and a pillow base are arranged on both longitudinal sides. Have been. The above-mentioned guide rail is provided with a transmission belt reciprocated by a driving device and a moving body having a rotatable massage roller, and the moving body is connected to the transmission belt. Then, when the transmission belt is reciprocated by the driving device,
Accordingly, the moving body also reciprocates, so that the user lying on his or her back can receive a massage by the massage roller of the reciprocating moving body.

In this case, the connecting structure of the moving body to the power transmission belt is such that two mounting plates are attached to the power transmission belt, and an intermediate portion of one connecting wire is connected to the two mounting plates. ,
Both ends of the connecting wire are extended upward at an acute angle and connected to a moving body.

[0004]

The massage device can be folded in two when not in use. However, at this time, if the moving body is located in a portion folded for folding in two, The guide rail, which had been straight before, bends in a semicircle and tends to move away from the moving body. However, since the connecting wire connecting the guide rail and the moving body is one and has no margin, if the transmission belt is bent in a semicircular shape to move away from the moving body, the connecting wire is attached. As a result of pulling the transmission belt through the plate, the transmission belt may come off the guide rail.

When the transmission belt moves, the connecting wire moves the moving body by pulling it. In order to effectively transmit this pulling force to the moving body, both ends of the connecting wire are bent upward at an acute angle from the mounting plate and connected to the moving body, but since the transmission belt reciprocates, Both end portions extended upward from the mounting plate and connected to the moving body are pulled or loosened due to a change in the moving direction of the transmission belt. Then, the portion connected to the mounting plate and bent at an acute angle is repeatedly bent and stretched in the opposite direction, and may be broken by fatigue in due course.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a power transmission strip even when the base is folded in two even if the moving body is located at the portion bent for the folding. It is an object of the present invention to provide a massage device capable of preventing a member from coming off a base body and preventing a connecting wire connecting a moving body to a transmission strip member from being broken for a long time.

[0007]

In order to achieve the above object, a massage device according to the present invention supports a transmission strip member reciprocated by a driving device and a massage roller on a guide rail which can be bent at an intermediate portion. A movable body rotatably supported by the power transmission member, and connecting the movable body to the transmission strip member to reciprocate the moving body by reciprocating the transmission strip member. Two mounting plates are attached to the strip member at intervals in the direction of movement, and the two connecting wires are connected to the intermediate portions of the two connecting wires, respectively, and both ends of the two connecting wires are connected. Of the portion, one end on the inner side led out between the two mounting plates is extended obliquely upward so as to intersect substantially in an X-shape, and the distal end is connected to the support, and the two mounting plates are connected. Is derived outside By connecting to the support by extending the other end upward, it is characterized in that it has connected the mobile to the transmission ridge member.

In this case, the support has a pair of guide portions bridging the other end sides of the two connection wires outside of a portion of the two connection wires connected to two mounting plates. It is preferable that the lower end of a portion of the guide portion that bridges the other end of the two connecting wires is formed into a curved surface.

Further, in order to reduce the number of parts, it is preferable that the guide portion is formed integrally with the support. Further, it is preferable that the transmission strip member is constituted by a metal belt, and that the two mounting plates are attached to the transmission strip member by welding at positions deviated toward the mating mounting plate side.

[0010]

According to the above means, a member for connecting the support of the moving body to the transmission strip member is constituted by two connecting wires,
Of the two ends of the two connecting wires, one end is extended obliquely upward so as to intersect substantially in an X-shape, and the leading ends are connected to the support. Therefore, when the guide rail is folded in two, even if the moving body is located at the bent portion and the transmission strip member is pulled through the connecting wire, there is a possibility that the transmission strip member is pulled with such a large force. As a result, the transmission belt does not come off the guide rail.

Further, since the other end of the two connecting wires is hung over the guide portion provided on the support, the two connecting wires are not bent and extended from the mounting plate at an acute angle, and are broken even if they are repeatedly bent and stretched. There is no fear of reaching.

Further, the power transmission strip member is formed of a metal belt, and the two mounting plates are attached to the power transmission strip member by welding at a position deviated toward the mating mounting plate side, thereby reducing the strength by welding. Can prevent the damage to the part.

The moving body 44 reciprocates on the guide rail 1 between both ends. A detecting device 61 is provided in the casing 17 of the driving device 16 to detect that the moving body 44 has traveled to the end on the pillow base 7 side and the end on the base member 8 side. This detection device 61
As shown in FIG. 18, a feed screw 62 fitted so as to rotate integrally with the rotating shaft 19, an operating member 63 having a screw hole 63 a screwed to the feed screw 62, and a casing 1.
7 and two switches 65 and 66 mounted on the mounting plate 64 at a predetermined distance from each other in the axial direction of the rotating shaft 19.
It is composed of

The upper part of the mounting plate 64 is shown in FIGS.
A hook 64a is formed, and a boss 64b is formed below the hook 64a. In contrast, the casing 17
At the top, a horizontally elongated hook hole 67 is formed, and at the bottom, a horizontally elongated through hole 68 is formed. The mounting plate 64 is fixed to the casing 17 by engaging the hooks 64 a with the hook holes 67 and screwing the mounting screws 69 passed through the through holes 68 to the boss portions 64 b. A flat guide 64c is projected from the mounting plate 64 between the switches 65 and 66. The guide 61c has a groove 6 formed at the distal end of the operating member 63.
3b is fitted. Thus, the operating member 63 is configured to move linearly in the axial direction of the rotary shaft 19, that is, in the left-right direction with the rotation of the feed screw 62 without rotating together with the feed screw 62. In this case, the feed screw 62 and the female screw of the screw hole 63a are multi-threaded screws, for example, double-threaded screws, thereby increasing the screw pitch and moving the operating member 63 per rotation of the rotary shaft 19. Is to be larger.

In the detection device 61, when the rotating shaft 19 is driven to rotate in the direction of arrow A and in the direction opposite to arrow A by the motor 18, the operating member 63 moves in the direction of arrow C and in the direction opposite to arrow C. The pressing portions 63c and 63d protruding from both sides of the operating member 63 press the leaf springs 65a and 66a of the switches 65 and 66, and press the switches 65 and 66.

The ON operation signals of the switches 65 and 66 are input to a control device 70 provided in the casing 17, and the control device 70 recognizes the input ON operation signal as a reverse rotation command signal and rotates the motor 18 up to that point. Control to rotate in the opposite direction.

Here, the number of rotations of the rotating shaft 19 required to move the operating member 63 between the position where the switch 65 is turned on and the position where the switch 66 is turned on is determined by setting the transmission belt 2 to the moving body 44. And the number of rotations required to wind the first and second driving pulleys 22, 23 and 24, 25 by a length corresponding to the movement distance between the two end point positions. Accordingly, from the above, the moving body 44 moves in one direction from the end point position on the pillow base 7 side and travels in the other direction when traveling to the end point position on the pedestal member 8 side, and moves in the other direction. When the vehicle travels to each end point position, the vehicle reverses and moves in the opposite direction to the previous moving direction.

In this case, when the moving body 44 has traveled to the end point near the pillow base 7 and the end point near the base member 8, the switches 65 and 66 are fixed to the mounting plate 64 so that the operating members 63 turn on. The position needs to be adjusted. For this adjustment, the hook hole 67 and the through hole 68 are made horizontally long so that the mounting plate 64 can be moved in the horizontal direction by an amount corresponding to the length of the hook hole 67 and the through hole 68. An adjustment mechanism 71 for finely adjusting the position of the plate 64 is provided. The adjusting mechanism 71 mainly includes an adjusting screw 72 as shown in FIG. 21, and the adjusting screw 72 is screwed into a nut 73 attached to the casing 17. A groove 72a is formed at the tip of the adjusting screw 72, and a holding piece 64d formed on the mounting plate 64 is formed in the groove 72a.
Are fitted. Therefore, when the adjusting screw 72 is rotated forward and backward, the adjusting screw 72 advances and retreats with respect to the nut 73,
Due to the screw advance / retreat movement, the mounting plate 64 moves in the left-right direction (the rotation shaft 1).

As will be understood from the above description, the fixing position of the mounting plate 64 is determined when the moving body 44 reaches the end point position on the pillow base 7 side and the end point position on the base member 8 side. Must be adjusted so that the switches 65 and 66 are turned on. For this position adjustment, as shown in FIG. 4, the guide rail 1 and the pillow base 7 are provided with marks 74a and 74b for indicating at least one of both end positions in this embodiment. .

The position adjustment of the mounting plate 64 using the marks 74a and 74b is performed as follows. That is, first, the moving body 44 is moved to the end point position on the pillow base 7 side or the end point position on the base member 8 side, and the predetermined position of the moving body 44, for example, the moving direction end of the moving body 44 is marked 74a or 74.
Stop at the position that matches b. Next, in a state where the mounting screw 69 is loosened, the adjusting screw 72 is advanced and retracted to mount the mounting plate 6.
4 is moved left and right. Then, when the moving body 44 is stopped at the end point position (mark 74a) on the pillow base 7 side, the switch 65 is moved to a position where it is turned on by the pressing portion 63c of the operating member 63, and When stopping at the end point position (mark 74b), the switch 6
6 moves to a position where the pressing portion 63c of the operating member 63 is turned on. Thereafter, the mounting plate 69 is fixed to the casing 17 by tightening the mounting screw 69, and the adjusting screw 7
The adjustment screw 72 is fixed so as not to be loosened by tightening the lock nut 75 screwed into the nut 2. At this time, the interval between the two switches 65 and 66 is determined in advance to be equivalent to the distance (moving stroke) in which the moving body 44 moves between both end point positions. If the operation member 63 is turned on, the position of the mounting plate 64 has been adjusted, and the positions of the switches 65 and 66 do not need to be adjusted again.

As shown in FIGS. 4, 6, 7, and 17,
A flat heater 76 is disposed between the pair of guide rails 1 below the massage roller 42, and a support plate 77 is disposed below the flat heater 76. The flat heater 76 is unitized in a mat shape by sandwiching a heater wire 80 between the cushion member 78 made of foamed plastic and a cover member 79 made of felt, for example, and bonding the heater wire 80 therebetween. Thus, it is placed on the support plate 77. The support plate 77 is made of a hard plastic such as polypropylene, and has a so-called rigid shape.

The left and right sides of the flat heater 76 and the support plate 77 are placed on a hollow portion 1g one step lower than the main plate portion 1b located inside the guide rail 1 as shown in FIG. Accordingly, the guide rail 1 is pressed from above by a pressing plate 82 fixed to the main plate portion 1b of the guide rail 1. Therefore, the left and right sides of the flat heater 76 and the support plate 77 are sandwiched between the hollow portion 1g of the guide rail 1 and the holding plate 82. The ends of the flat heater 76 and the support plate 77 on the driving device 16 side are mounted on the base member 8, and the ends on the pillow base 7 side are arranged on the pillow base 7 as shown in FIG. It is inserted and held between 7h.

The heater wire 80 of the flat heater 76
6 and 7 are arranged in a meandering shape except for an intermediate portion corresponding to the flexible portion 6 of the guide rail 1 as shown in FIGS.
Are arranged linearly. In this case, the heater wire 80 is located in an area within a predetermined distance from the pillow base 7 on the pillow base 7 side of the flat heater 76.
Are not provided, so that the user's head placed on the pillow base 7 is not heated.

As shown in FIG. 6, both ends of the heater wire 80 are connected to a lead wire 83 by soldering at a relay terminal block 84. This relay terminal block 84
Is resin-molded including the end of the heater wire 80 and the end of the lead wire 83, and is brought into a state of a waterproof connection structure by the resin mold. Then, as shown in FIG. 22, the female connector 8 connected to the distal end of the lead wire 83 is formed.
5 is a plastic case 8 for storing the control device 70
6 and connected to a male connector 87 serving as a power supply unit.

As described above, the guide rail 1 has the flexible portion 6
And can be folded in half. A bend detecting device 88 is provided to prevent the motor 18 and the heater wire 80 from being energized when the guide rail 1 is bent. As shown in FIGS. 22 to 24, the bending detecting device 88 includes a case 86 of the control device 70.
A slide member 90 housed slidably in the longitudinal direction of the guide rail 1 in a box-shaped guide portion 89 as a holding portion integrally formed on the lower side, and a seat portion 89a formed in the guide portion 89 and a slide. Arrow D, which is disposed between the flexible member 6 and the member 90,
When the slide member 90 slides in the direction opposite to the arrow D, the compression coil spring 91 acting as an elastic body and the plate spring 92a pressed by the protrusion 90a of the slide member 90 are turned on. The switch 92 has one end connected to the slide member 90 and the other end connected to the guide rail 1 on the pillow base 7 side of the flexible portion 6 with a screw 9.
3 is constituted by a wire 94 made of one metal wire as a bending detection member fixed by 3. Here, the connection configuration of the wire 94 to the slide member 90 is shown in FIG.
As shown in FIG. 7, one end of the wire 94 is bent into a loop portion 94a as a long hole-shaped connecting portion, and a screw 95 passed through the loop portion 94a is screwed to the slide member 90.

The portion of the wire 94 facing the flexible portion 6 is formed in a coil portion 94b as a bendable portion for absorbing the bending of the flexible portion 6. When the guide rail 1 is extended, the wire 94 is pulled in the direction opposite to the arrow D as shown by a solid line in FIG. 22 to move the slide member 90 in the same direction against the elastic force of the compression coil spring 91. Then, the switch 92 is turned on. Conversely, when the guide rail 1 is bent by the flexible part 6, the coil part 94b is bent and the wire 9 is bent as shown by a two-dot chain line in FIG.
4 is moved in the direction of arrow D,
0 moves in the direction of arrow D to turn off the switch 92. When the switch 92 is off, the control device 70 determines that the guide rail 1 is bent, and prevents the motor 18 and the heater wire 80 from being energized.

A power switch 96 is mounted on the rear surface of the casing 17 as shown in FIG. 4, and a power cord 97 and a remote control box 98 connected to the control device 70 are connected from the rear surface of the casing 17. Code 99 is derived. As shown in FIGS. 4 to 6 and FIG. 22, a cover 100 for covering the casing 17, the first and second drive rollers 22 to 25, the tension mechanism 35, and the like is provided on the casing 17 with screws 101 (FIG. 19). , See FIG. 21).

Here, the control device 70 includes a microcomputer (not shown). The controller 70 energizes the motor 18 when the massage operation is selected by operating the remote control box 98, and energizes the heater wire 80 when the warming operation is selected. Then, when the warming operation is started, the timer function of the microcomputer or the timer operation of a separately provided timer is started, and even after a lapse of a predetermined time, for example, 8 hours from the start of the warming operation, the warming operation is not stopped. If not, the heater wire 80 is turned off. In this warming-up operation, the control device 70 controls the power supply through the heater wire 80 based on a detection signal of a temperature sensor (not shown) provided at a predetermined portion of the flat heater 76 to control the flat heater 76 to a predetermined temperature. Maintain temperature.

By the way, the moving body 44 is driven at a speed of moving between both end positions in, for example, 43 seconds. During the massage operation, the control device 70 turns on either one of the switches 65 and 66 of the detection device 61 and then turns on the moving body 44 for a longer time than the required moving time between the two end positions. For a certain time, for example, 1 minute 43
If another switch is not turned on even after the elapse of seconds, the motor 18 is turned off and the massage operation is automatically stopped. As the motor 18, a high-quality motor that does not burn out even when energized for about one hour while the rotation is locked is used. Further, when the operation of stopping the massage operation is performed by the remote control box 98, the control device 70 switches 6 to detect that the moving body 44 has reached the end point position on the base member 8 side.
The motor 18 is turned on until the switch 6 is turned on, and when it is detected that the switch 66 is turned on, the motor 1 is turned on.
The power supply 8 is turned off to stop the moving body at the end point on the base member 8 side.

As shown in FIG. 6 and FIG.
A pair of prism-shaped cushion members 102 is fixed to the outer half of the main plate portion 1b. This cushion member 10
2 is set to be considerably thicker than the flat heater 76, whereby the pair of cushion members 102 is configured to be depressed, and when the user lays upward on the flat heater 76, The cushion member 102 is supported from both sides and held so as not to roll out.

The main body 103 of the massage device is constituted as described above, and the main body 103 is formed of a cloth-shaped interior body 1 having a bag shape.
04 and the exterior body 105. Of these, the inner body 104 includes a cushion material 106 such as urethane foam except for a portion covering a region where the massage rollers 42 and 43 move, and the outer body 105 has a cushion material 107 such as cotton except for the lower half. Is included.

Then, two bands 108 and 109 shown in FIG. 25 are attached to the exterior body 105 by a magic tape (trade name) 110, and the flexible portion 6 of the guide rail 1 is bent to massage the device. 25 is folded in two as shown in FIG. 25, the tip portions of the two bands 108 and 109 are connected by a magic tape 111 so that the massage device can be held in a folded state.

In order to receive a massage by the massage device configured as described above, the guide rail 1 and thus the massage device are extended as shown in FIG.
After the power switch 96 is turned on, the head is placed on the pillow base 7 and the body is laid on the flat heater 76.

After lying on the plane heater 76, the massage operation is started by operating the remote control box 98. Then, the motor 18 is started, whereby the transmission belt 2 is taken up by the first driving rollers 22 and 23 (rewinded from the second driving rollers 24 and 25) or the second driving roller The moving body 44 reciprocates by being taken up by the rollers 24 and 25 (rewinded from the first driving rollers 22 and 23). The reciprocating movement of the moving body 44 causes the massage rollers 42, 4 to move.
3 moves while rotating against the back and feet via the inner body 104 and the outer body 105, thereby receiving a massage action.

On the other hand, especially when the temperature is low such as in winter,
The warming operation is started at the same time as the start of the massage operation.
Then, the heater wire 80 generates heat, which warms the body and improves blood circulation.
A more favorable massage effect can be obtained by a synergistic effect with the massage by No. 3. At this time, the heater wire 80 is controlled by the control device 70 to maintain a constant temperature to warm the body to an appropriate temperature, but the heater wire 80 is not provided in an area within a predetermined distance from the pillow base 7. Therefore, it is possible to prevent a problem that the head is heated up. In the flat heater 76, a portion corresponding to the flexible portion 6 of the guide rail 1 has a low calorific value because the heater wire 80 is straight, but this portion is a portion of the body where the buttocks hit. There is no particular problem.

When the massage rollers 42 and 43 roll while massaging the body during the massage operation, the moving body 44 receives a resistance force.
Portions of the connection wires 56 and 57 that are led out from the connection plates 51 and 52 (hereinafter, outer portions) are pulled or loosened with the reciprocating movement of the moving body 44. At this time, the outer portions of the connecting wires 56 and 57 are
Since it is hung on the curved surfaces 55aa and 55bb of the a and 55b, it is maintained in a curved state and does not bend at an acute angle. Therefore, due to the reciprocating movement of the moving body 44,
Even if the outer portions of the connecting wires 56 and 57 are repeatedly pulled or loosened, there is no risk of cutting due to fatigue.

When the massage rollers 42 and 43 roll from the concave portion to the convex portion of the body, a large resistance force is applied thereto, and the distal end of the support 46 in the moving direction is guided by the guide rail 1.
It comes to emerge from. Then, the connecting wires 56,
Since the outer portion of the connecting plate 57 pulls up the outer end of the connecting plate 51, 52, the inner end of the connecting plate 51, 52 remains in contact with the guide rail 1, but the outer end of the connecting plate 51, 52 has the guide rail. It starts to rise from 1. As a result, as shown in FIG. 3A, the transmission belt 2 also comes up from the guide rail 1 and pushes the outer end of the auxiliary plate 53 downward.

In this case, since the position of the spot weld W is biased toward the inner end of the connecting plates 51 and 52, the auxiliary plate 53
Is relatively long from the spot welding W to the outer end, and is curved when pushed down by the transmission belt 2. For this reason, the transmission belt 2 also bends in a curved state in the same manner. Therefore, even if the outer ends of the connecting plates 51 and 52 are repeatedly lifted off the guide rail 1, the transmission belt 2 becomes fatigued. There is no danger of cutting.

When the outer ends of the connecting plates 51 and 52 rise from the guide rail 1, the connecting plates 51 and 52 receive a tensile force from the guide rail 1 at the spot weld W portions. On the other hand, when the connection plates 51 and 52 are welded, the periphery of the welded portion becomes brittle, but the position of the spot weld W is biased toward the inner end, so that the brittle portion extends to the outer end. Disappears. If the spot welding is near the outer ends of the mounting plates 51 and 52, the outer ends become brittle, and if the spot welded portion is repeatedly subjected to a tensile force from the guide rail 1, the outer side may be repeatedly pressed. Although there is a possibility that the end portion may be fatigued and break, there is no such a possibility in the present embodiment.

Now, after receiving the massage for a desired time, the operation of stopping the massage operation by the remote control box 98 is performed.
When the motor reaches the end point on the side of the base member 8, the motor 18 is turned off. Thereafter, the massage device is folded and stored.

At this time, if the massage operation is stopped by turning off the power switch 96, the moving body 44 may stop when the movable body 44 is located at the flexible portion 6 of the guide rail 1. When the massage device is folded in two in this state, as shown in FIG.
Is trying to bend outward in an arc shape with both ends of the support 46 sandwiched therebetween, so that the connecting wires 56 and 57 pull the transmission belt 2. In this case, if the connecting wire is formed of a single wire, there is not enough room for the length, so that the transmission belt may be pulled more strongly and come off from the guide rail 1. However, in the present embodiment, there are two connecting wires 56 and 57, and a portion (hereinafter referred to as an inner portion) led inward from each of the connecting plates 51 and 52 crosses in a substantially X-shape and is a farther tube. Part 54a,
Since the connecting wires 54b are connected, the inner portions of the connecting wires 56 and 57 also have a sufficient margin in length. For this reason, since the connecting wires 56 and 57 do not pull the transmission belt 2 so strongly, there is no possibility that the transmission belt 2 comes off the guide rail 1.

FIG. 26 shows another embodiment of the present invention. The difference from the above-described embodiment is that the guide portions 55a, 55
5b is formed integrally with the support 46. This eliminates the need for a separate protective plate 55,
The number of parts can be reduced.

The present invention may be applied to a massage device having a configuration in which a guide rail, a pillow base, a driving device, a moving body, and the like are arranged on a flat substrate. The number of guide rails and transmission belts may be one, and a plurality of moving bodies 44 may be provided.

[0067]

As described above, according to the present invention, the following effects can be obtained. In the massage device according to the first aspect, the member for connecting the support of the moving body to the transmission strip member is constituted by two connecting wires, and one end of the two connecting wires is substantially X-shaped. Since it is configured to extend diagonally upward so as to intersect with and connect to the support, the connecting wire has a margin of length, so when the guide rail is folded in two, the moving body is positioned at the bent portion. Therefore, even if the transmission strip member is pulled via the connecting wire, there is no possibility that the transmission strip member is pulled with a very strong force, and the transmission-shaped member does not come off the guide rail.

In the massage device according to the second aspect, the support is provided with a pair of guide portions for bridging the other ends of the two connecting wires, and the lower end of the guide portion is formed into a curved surface. There is no fear that the connecting wire is broken due to fatigue. In the massage device according to the third aspect, since the guide portion is formed integrally with the support, the number of components can be reduced.

In the massage device according to the fourth aspect, the transmission strip member is constituted by a metal belt, and the two mounting plates are attached to the transmission strip member by welding at a position biased toward the mating mounting plate side. With this configuration, damage to the mounting plate can be prevented.
