The belt 37 is always held in a state of being stretched in the longitudinal direction by the interposition of the spring 38.
As shown in (1), the protrusion preventing ribs 5a and the receiving ribs 5b protrude, so that the belt 37 moves following the reciprocation of the traveling body 3 and always covers almost the entire long groove 5 reliably. As shown in FIG. 3, the feed screw 9 and the long groove 5 are arranged in parallel, but are separated from each other by an appropriate distance δ when viewed from above. This prevents foreign matter from attaching to the drive mechanism even when foreign matter enters the inside of the base 2 from the long groove 5.

Next, an operation device 70 for remotely operating the stretching device 1 of the present embodiment will be described. The operating device 70 is a so-called infrared remote controller. The infrared light transmitted from the operating device 70 is received by a light receiving circuit 80 provided in the base 2 by being connected to the base circuit 18. A signal for controlling the normal rotation or the reversal of the motor 6 with a desired reciprocating width or method is supplied to a control unit of a microcomputer mounted in the circuit 18. As shown in FIG. 7, a plurality of various buttons are provided on the operating device 70. Among them, an on / off button 71 provided on an upper end portion of the operating device 70 starts or ends the operation of the traveling body 3. Stop button 72
Is the traveling body 3 when an emergency occurs during operation.
This is to stop the exercise immediately on the spot. However, the control unit controls the traveling body 3 to wait for a certain period of time between receiving the instruction to start the reciprocating motion by pressing the ON / OFF button 71 and starting the reciprocating motion of the traveling body 3. Things. The weak button 73, the middle button 74, and the strong button 75, which are arranged at the lower end of the operating device 70 as a traveling width selection unit, are provided with three types of reciprocating movements provided by the control unit when each of them is pressed. The user 90 can freely select from the width.
When the button is pressed, the control unit that has received the signal via the light receiving circuit 80 causes the traveling body 3 to reciprocate repeatedly over the entire stroke from one end of the long groove 5 to the other. When the weak button 73 is pressed with 2/3 of the full stroke, 1/1 of the full stroke
With the stroke of 3, the traveling body 3 is caused to reciprocate repeatedly.

There are a total of four types of travel modes that define the method of reciprocation of the traveling body 3 provided in the control unit. These modes are a double-ended stop button 76, a continuous operation button 77, a left end Stop button 78, right end stop button 7
9 can be freely selected by operating the buttons of the traveling mode selection section. Among these traveling modes, the both-ends stop mode selected by pressing the both-ends stop button 76 is one in which the traveling body 3 stops for a predetermined period of time, for example, 4 seconds in the reversing section at both ends in the reciprocating motion. Yes, it is used to perform static stretching, which is generally called in stretching. The continuous operation mode selected by pressing the continuous operation button 77 is as follows.
The traveling body 3 is immediately reversed without stopping at the reversing portions at both ends, and reciprocating motion is repeated. Left end stop button 78
Is the leftmost stop mode selected by pressing
Reference numeral 0 denotes a reversing portion in which the traveling body 3 stops for a predetermined time and reciprocates at a reversing portion at the left end when viewed from the front 2b side.
The right end stop mode selected by pressing the button 9 is a mode in which the traveling body 3 stops and moves reciprocally for a predetermined time at the right end reversing section when the user 90 is viewed from the front 2b side. However, the front surface 2b as used herein refers to the surface of the base 2 on which the user 90 is located when performing the below-described shoulder stretching and waist stretching.

In order for the control unit mounted in the microcomputer to perform the control in each of the reciprocating widths and the running modes described above, the control unit needs to process the detection information of the position of the traveling body 3.
For this purpose, a position sensor 81 is provided on the bottom plate 11 of the base 2 as shown in FIG. The position sensor 81 is installed via a gear press-fitted at a position outside the bearing 20 of the feed screw 9 and on the side opposite to the side to which the second pulley 21 is connected. Detect and feed plate 23
, That is, the position of the traveling body 3 is detected.

FIG. 18 shows a more detailed configuration of the position sensor 81. The position sensor 81 includes a first reduction gear 83 and a second reduction gear 8 in a position sensor housing 82.
4. The disk surfaces of the photointerrupter 86 and the light-receiving element (not shown) of the photointerrupter 86 are arranged side by side with the disc surfaces facing each other in the same direction so as to mesh with the position detecting rotary plate 85 in order. )). With the above configuration, the rotation of the motor 6 causes the feed screw 9 to rotate via the first pulley 19, the connection belt 22, and the second pulley 21.
The first pressurized gear 83, the second reducer gear 84, and the position detecting rotary plate 85 rotate in the position sensor housing 82 while being meshed in this order. The position detection rotary plate 85 is provided with a 3-bit slit 86. By inputting the presence or absence of detection by the light receiving element of the photointerrupter 86 according to the position of the slit 86 to the control unit of the microcomputer, the control unit performs the 3-bit control. Knows the position of the traveling body 3 based on the input signal of
The rotation of the motor 6 can be controlled in accordance with the set reciprocating width and running mode.

FIG. 19 is an explanatory diagram of an input signal of the position sensor 81, and FIG. 20 is a control block diagram. As described above, the position of the traveling body 3 by the position sensor 81 is input in 3 bits, the first sensor input is located at both end positions, the second sensor input is located at the center position, and the third sensor input is operated in the operating area. By assigning each detection as a position, more strict operation control becomes possible. The advantage of using the above allocation is that, for example, 00
When an area is assigned as 0, 001, 010, 011 or the like, a different signal indicating an area that does not exist is detected due to a shift between the position detection rotary plate 85 and the photo interrupter 86, and the position of the traveling body 3 is not known. There is a danger of malfunctioning, but such a malfunction is prevented. However, in this example as well, it is conceivable that, for example, a different signal of 001 or 010 is input when a signal of 001 is required at both ends and the center, so that the control unit has a function of canceling the different signal. When a different signal is generated, a malfunction is prevented by detecting signals at both ends and only the center and performing a cancel reset correction of the different signal.

In the case of the operation system using the motor 6 as in the present embodiment, when the motor 6 stops and slips due to inertia, the motor 6 goes beyond the authorized stop area and enters the next area. There is. If the operation is repeated without correcting this, the operation range will change little by little, and it is conceivable that the operation will be shifted or a failure will occur due to overrun. In view of this, the control unit of this embodiment is provided with an area correction function so that the slip amount is counted during the operation, and the next time the operation is reversed, the slip correction is performed. As a result, stable operation can be maintained at all times, and there is no need for a circuit such as a brake.

In the case of the operation system using the motor 6 as in the present embodiment, the rotation speed of the motor 6 is substantially constant, and the input signal from the position sensor 81 continues for a substantially constant period of time. It changes to the signal of. Therefore, when the duration of the input signal changes, it can be determined that some abnormal state has occurred. Therefore, the control unit of the present embodiment detects an abnormality by performing time management of the input signal as a protection function. In addition, it has a function of stopping the operation in the event of an abnormality to protect the user 90 and the device. Furthermore, for example, if it is judged that an overrun has occurred, it is reversed immediately after entering the area and returned to the center position. To prevent destruction in the equipment. This eliminates the need for a circuit or the like for overcurrent protection, thereby enabling cost reduction and circuit miniaturization.

Hereinafter, a method of stretching and massage which can be performed by using the stretching device 1 of this embodiment will be described. First, the stretching of the shoulder shown in FIG. 8 will be described. However, the front surface 2b described below is a surface facing the orthogonal direction of the base 2 and a surface on which the handgrip portion 36 is provided. As shown in FIG. 8 (a), the user 90 first turns his / her head to the center of the front surface 2b of the base 2 and lays down on his / her back so that the whole body faces in the orthogonal direction, and holds the handgrip 36 with both hands. Grab and prepare.
Then, the button 7 provided in the traveling width selection unit of the operating device 70
A desired travel width, that is, exercise intensity is selected by pressing any of the buttons 3 to 75, and a desired travel mode is selected by pressing any of the buttons 76 to 79 provided in the travel mode selection unit. After that, when the on / off button 71 is pressed, the traveling body 3 starts to move after the user 90 waits for a predetermined time for preparing the preparation posture, and the traveling body 3 reciprocates in the set traveling width and traveling mode. Things. After a predetermined number of reciprocating motions, the traveling body 3 returns to the center position and stops. In this example, the waiting time before the traveling body 3 starts to move is set to 4 seconds, and the predetermined number of reciprocations of the traveling body 3 is set to 10 times. Therefore 10
If the number of times is not enough, the on / off button 71 may be pressed again to repeat the one-set reciprocating motion. To stop the operation halfway, the stop button 72 may be pressed.

According to the above method, the arm of the user 90 is forcibly swung right and left and the shoulder is stretched. However, since the flexibility of the shoulder varies among individuals, the running width and the The strength of the stretch can be freely changed by changing the running mode. Further, changing the posture of the user 90 can also freely change the strength of the stretch. For example, the arms are bent from the weakest strength performed by bending the arms and gripping the handgrip portion 36, and the arms are moved from the weakest stretch. Stretching stronger than gripping the handgrip 36 in the stretched state, stretching with the arms crossed over the head and gripping the handgrip 36, or head position on the front 2b Stretches of various strengths can be freely performed, such as stretching by positioning the body to the left or right instead of the center. Also, if a person whose body is initially rigid and low in flexibility improves the flexibility by continuously using the stretching device 1 of the present example, it is only necessary to perform stretching with higher strength. It can be used for a long time stretching just by preparing one.

In this example, in order to facilitate the above-mentioned shoulder massage, the hand of the user 90 only enters between the base 2 and the handgrip 36 when the handgrip 36 is grasped from below. And an upper portion of the front surface 2b located below the handgrip portion 36 so that the arm of the user 90 does not contact the base 2 when the handgrip portion 36 is grasped from below. And an inclined surface 88 having an inclination such that the skirt becomes wider as approaching from the upper surface 2a side to the bottom surface side.

Next, the waist stretching shown in FIG. 9 will be described, but the description of the same contents as those of the shoulder stretching will be omitted. As shown in FIG. 9 (a), in the case of this stretching, the central part of the upper surface of the limb rest 4 is used as the foot rest 4a, and both feet are placed on the foot rest 4a and the whole body is oriented in the orthogonal direction. When the button operation of the operating device 70 is performed while lying on the back as described above, the waist can be stretched by forcibly shaking both feet left and right by the reciprocating motion of the traveling body 3. Since the upper surface of the limb rest 4, that is, the foot rest 4 a is formed on an inverted arch projecting downward, even when the limb rest 4 moves to the left and right, the user 90 can comfortably place his or her feet and keep their feet. Is prevented from falling. Further, the width of the limb rest 4 in the orthogonal direction is set to a width that can be easily placed from the heel of the user 90 to the vicinity of the knee joint in stretching the waist.

In this waist stretching, the user 9
The stretching strength can be changed by changing the posture to 0, and when performing with the upper body raised as shown in FIG. 9C, the stretching is weaker than when lying on the back. In addition, regarding the part of the foot to be placed, when the ankle is placed, when the calf is placed, and when the knee joint is placed, the stretch becomes strong in order. Further, regarding the positioning of the body, the stretching strength can be changed by moving the body 2 not to the center but to the left or right with respect to the front surface 2b of the base 2. The stretching device 1 of the present example is capable of performing stretching according to the flexibility of the user 90 by combining these methods.

Next, the stretching of the upper body and feet shown in FIG. 10 will be described, but the description of the same contents as in the case of the stretching of the shoulder will be omitted. However, the side surface 2c described below is a surface of the base 2 that faces in the reciprocating direction. As shown in FIG. 10B, in the case of this stretching, the multipurpose projection 33 formed on the upper surface of the limb rest 4 is used as a hand grip. The user 90 is positioned so as to face the side surface 2c, raises his / her upper body, extends his / her legs, grasps the multipurpose protrusion 33 with both hands while holding the base 2 with both legs, and presses the button of the operation device 70. The so-called forward bending is forcibly performed by reciprocating the running body 3 by the operation, and the upper body and the legs are stretched. However, the user 90 may be positioned on either the right or left side of the front surface 2b.

Also in the stretching of the upper body and the legs, the stretching strength can be changed by changing the posture of the user 90. The stretching is performed by bending the knees and sitting as shown in FIG. 10C. This is a stretch that is weaker than when performing the stretching. In addition, since the multipurpose projections 33 are provided at both ends of the upper surface of the hand-held table 4, a stretch that is stronger when gripping a person farther from the body than when gripping a closer one is achieved. Further, as for the traveling mode to be selected, when the user 90 is positioned on the right side when viewed from the front 2b side, by selecting the left end stop mode, the most forwardly bent posture is maintained for a certain period of time. As a result, the stretching effect increases. Similarly, when the user 90 is positioned on the left side when viewed from the front 2b side, the stretching effect is increased by selecting the right end stop mode.

Next, the stretching of the ankle shown in FIG. 11 will be described, but the description of the same contents as in the case of the stretching of the shoulder will be omitted. As shown in FIG.
In the case of this stretching, the multipurpose projection 33 is used as a sole mounting portion. The user 90 is positioned so as to face the side surface 2c and places the soles of both feet on the multipurpose protruding portion 33 closer to the body with the upper body lying down on the back. By reciprocating, the so-called bending and stretching movement of the foot is forcibly performed to stretch the ankle and the entire foot. However, the user 90 may be positioned on either the right or left side of the front surface 2b.
In addition, it is not necessary to place both feet on the multipurpose projection 33 and stretch them.

Also in the stretching of the ankle, the stretching strength can be changed by changing the posture of the user 90. As shown in FIG. 11 (c), the stretching is performed with the upper body raised and supported by both hands. It becomes a strong stretch. Also, the closer the distance between the base 2 and the buttocks of the user 90 is, the stronger the stretch becomes. Further, as for the traveling mode to be selected, when the user 90 is positioned on the right side when viewed from the front 2b side, by selecting the right end stop mode, the state in which the foot is bent most is maintained for a certain time. As a result, the stretching effect is increased. Similarly, when the user 90 is positioned on the left side when viewed from the front 2b side, selecting the left end stop mode increases the stretching effect.

Next, the calf massage shown in FIG. 12 will be described, but the description of the same contents as in the case of the shoulder stretching will be omitted. As shown in FIG. 12B, in the case of this stretching, the multipurpose projection 33 is used as a calf mounting portion. The user 90 is positioned so as to face the side surface 2c and put his / her calf on the multipurpose projection 33 while lying on his / her back,
By reciprocating the running body 3 by operating the button of the operating device 70, a calf massage is performed. However, the user 90 may be positioned on either the right or left side of the front surface 2b.
