Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exercise training apparatus in which a user walks or runs on an endless track surface rotated by a driving means, and more particularly to a rehabilitation (hereinafter, referred to as rehabilitation).
Abbreviated as rehabilitation. The present invention relates to an exercise training device suitable for walking training for the purpose of (1), running training of first-rate athletes who participate in marathon competitions from jogging of general runners, and walking for the purpose of dieting and the like.

[0002]

2. Description of the Related Art An exercise training device that detects the position of a user (runner or pedestrian) and changes the traveling speed of a movable surface in an endless track is disclosed in Japanese Patent Publication No. 2-47231 and Japanese Patent Application Laid-Open No. 63-309280. It is disclosed in gazettes and the like.

[0003] The exercise training device disclosed in Japanese Patent Publication No. 2-47231 performs constant-speed driving of a movable surface when the user is located within a predetermined range on the movable surface, and the position of the user is movable. When the value deviates from a predetermined range on the surface, an on / off operation of positive or negative acceleration is executed. More specifically, when the position of the runner on the movable surface gradually advances and exceeds the advance limit line, acceleration control is performed so that the movable surface accelerates by one step, and the position of the runner gradually retreats and retreats. When exceeding the limit line, deceleration control is performed so that the movable surface decelerates by one step.

The exercise training device disclosed in Japanese Patent Application Laid-Open No. 63-309280 also performs acceleration and deceleration when the runner deviates from a predetermined range on the movable surface, and based on the distance between the runner and the distance measuring device. The change rate (acceleration) of the speed of the movable surface is given.

[0005] That is, in the above-mentioned conventional apparatus, the user does not perform aggressive control during constant-speed running while staying within the set range, and accelerates (decreases) acceleration and deceleration when the position of the runner is out of the set range due to speed change. Speed) control is adopted, and constant speed running is the default state. The speed of the movable surface is determined as a result of the acceleration control.

[0006]

When a user accelerates on a movable surface, the position of the user moves forward of the movable surface. In the above prior art, the movable surface is accelerated / decelerated according to the position of the user on the movable surface. When the distance measuring device is arranged in front of the user, the distance measuring device increases the rotation speed of the movable surface when detecting that the distance to the user has become short. For example, if the instructor places a hand between the distance measuring device and the user while the user is traveling, if a shield enters between the user and the distance detector, the distance measuring device Is regarded as accelerated, and the rotational speed of the movable surface is increased. Therefore, there is a danger that the movable surface is accelerated against the intention of the user, and the user falls down without being able to cope with the acceleration or falls from the rear of the device.

[0007] In order to solve this problem, there is an arrangement in which a distance measuring device is provided behind a user. When detecting that the distance to the user has increased, the rotational speed of the movable surface is increased. The movable surface is decelerated against the intention of the user when the instructor blocks the distance measuring device and the user, but when the user is traveling normally, the deceleration is faster than unexpected acceleration. Is easier to respond to. For this reason, it is more secure to provide the distance measuring device behind the user.

However, when the distance measuring device is provided behind the user, troubles may occur in the device, such as the distance measuring device erroneously detecting the position of the user due to an abnormality of the device or an abnormal control signal. If the movable surface stops decelerating or stopping, or if the user suddenly stops traveling and cannot follow the deceleration of the movable surface, the user is transported backward with the movement of the movable surface and a distance measuring device is used. And the distance measuring device is damaged. Further, when the user falls from behind, the collision with the distance measuring device causes a problem that the degree of damage to the user increases.

An object of the present invention is to provide an exercise training apparatus that allows a user to exercise safely without damaging a distance measuring device even when the user is carried backward by movement of a movable surface. Is to do.

[0010]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention is characterized in that an endless track mechanism having a movable surface on which a user walks or runs and a control signal input from the outside. Driving means for driving the endless track mechanism so that the movable surface moves at a predetermined speed, and a position deviation for detecting a position deviation from a reference position set on the movable surface to a user position on the movable surface. Detecting means, input the position deviation detected by the position deviation detecting means,
An exercise training device having control means for transmitting the control signal to the driving means, wherein the movable surface is located near an end of the movable surface in a direction in which the movable means moves by the driving means and at a position where a user does not directly contact the movable surface. There is provided a position deviation detecting means support device for holding the position deviation detecting means.

Another feature of the present invention is that
Instead of the position deviation detecting means supporting device, a position deviation detecting means supporting device that holds the position deviation detecting means and retracts in the direction in which the collision force acts when a user collides is provided.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an exercise training device according to an embodiment of the present invention will be described.

FIG. 1 shows a partial schematic front view and a block diagram of a control system of an exercise training apparatus according to an embodiment of the present invention, and FIG. 2 shows a top view of the exercise training apparatus shown in FIG. In FIG. 2, a solid line indicates a state where the gate 11 is closed, and a dotted line indicates a state where the gate 11 is opened.

As shown in FIG. 1, two rollers 4 are mounted on a frame 3 and an endless track belt 1 is stretched between the two rollers 4. The user 10 runs on the upper surface (movable surface) of the endless track belt 1. The movable surface moves in a direction (rightward in the figure) opposite to a direction in which the user travels (leftward in the figure). Below the movable surface of the endless track belt 1, a support plate 2 that supports the weight of the user 10 over the entire range of the travel path length L is disposed. Further, a fixed base 18 that does not contact the movable surface is disposed at the rear end of the movable surface.

On both sides of the user 10, handrails 12 attached to the frame 3 are arranged. The rear part of the handrail 12 is fixed to a support 13 fixed to the frame 3. A gate 11 is attached to the support 13. The gate 11 is attached to one of the columns 13 in a door shape, and the open side of the gate 11 is connected to the other column 13 by a gate lock lever 14. A gate lock sensor 15 is provided on the column 13 side, and a gate lock sensor 16 is provided on the gate 11 side.
In the case where the gate 11 is closed by 4, the gate lock signal is supplied by the gate lock sensor 15 and the gate lock sensor 16. When the gate 11 is open, the gate lock sensor 15 and the gate lock sensor 16 are separated, and no gate closing signal is supplied. As shown in FIG.
Gate information from the gate lock sensors 15 and 16 is sent to the switch 8a.

As shown in FIG. 2, a buffer 21 is provided inside a gate 11 provided behind the user 10, and an ultrasonic sensor or an optical sensor is provided outside (back) of the buffer 21. The configured distance measuring device 8 is arranged.
The distance measuring device 8 uses the movable surface side (endless orbit belt 1 side) as a measurement area through an opening 21a formed through the cushioning material 21. The measuring beam emitted by the distance measuring device 8 is directed to the user 10 through the opening 21a of the cushioning material 21,
The light is reflected on the back of the user 10 and returns to the distance measuring device 8. As shown in FIG. 1, the distance measuring device 8 measures the positional deviation ΔX of the user 10 from the reference position 0 and sends it to the user intention reading device 7 as positional deviation information.

Gate information from the gate lock sensors 15 and 16 and positional deviation information from the distance measuring device 8 (position deviation △
X), the switch 8a sends a motor control signal to the motor drive 6 and the control information display 9
The control information and the gate information corresponding to the motor control signal are transmitted to the controller.

The user 10 performs muscular exercise according to his / her intention, and as a result, reaches a certain speed Vh at a certain time.
The movable surface of the endless track belt 1 moves at a speed Vm in a direction opposite to the traveling direction of the user 10. The distance measuring device 8 calculates the distance from the reference position 0 to the position of the user 10, that is, the position deviation ΔX.
Is measured. That is, the distance measured by the distance measuring device 8 fixed to the gate 11 is the speed Vh and the speed Vm.
Is the distance L2 between the user 10 moving at the speed ΔV, which is the difference from By calculating the difference between the distance L3 between the distance measuring device 8 and the reference position 0 and the distance L2 measured as the distance from the distance measuring device 8 to the user 10, the position deviation ΔX (ΔX = distance L2−distance L3) ) Is obtained.

On the endless orbit belt 1, an area in which the user 10 can safely exercise is predetermined, and the rear distance L4 is set as the rear limit position with reference to the reference position 0, and the front distance L is set.
5 is the front limit position.

The position deviation ΔX when the user 10 is located ahead of the reference position 0 is positive, and the position deviation ΔX when the user 10 is located behind the reference position 0 is negative. When the user 10 moves forward from the reference position 0, the position deviation ΔX becomes positive.

Next, the operation of the motor driving device 6 and the user intention reading device 7 will be described with reference to FIG. In addition,
Hereinafter, it is assumed that the user 10 travels.

It is assumed that the motor driving device 6 shown in FIG. 3 outputs a signal for rotating the motor 5 in only one direction, and the motor is stopped even when a reverse rotation command value is input. in this case,
The motor 5 rotates only in a direction for carrying the user backward.

When the user 10 closes the gate 11 and starts running on the endless track belt 1, the difference ΔV between the speed Vh of the user 10 with respect to the endless track belt 1 and the speed Vm of the endless track belt 1 with respect to the frame 3 is calculated. The user 10 moves with respect to the frame 3 at a speed. By integrating the speed difference ΔV, a position deviation ΔX with respect to the reference position 0 of the user 10 is generated.

The user 10 advances on the endless track belt 1,
When moving past the rear limit position and ahead of the reference position 0, the distance measuring device 8 detects that the positional deviation ΔX has become positive. The user intention reading device 7 determines the moving speed for driving the endless track belt 1 backward based on the position deviation ΔX, and sends a control signal Mc1 (hereinafter referred to as a signal Mc1) to the switch 8a.
Is sent. The user intention reading device 7 includes amplifiers 7a, 7
b, an integrator 7c and an adder 7d.

The amplifier 7a generates the acceleration command value Pa by adding the gain Ka to the position deviation ΔX given from the distance measuring device 8. The integrator 7c integrates the acceleration command value Pa over time to generate a speed command value Ps. Simultaneously with this processing, the amplifier 7b adds the gain Kv to the position deviation ΔX given from the distance measuring device 8 to generate the speed command value Pv. In the adder 7d, the speed command value Ps and the speed command value P
v is added to generate a signal Mc1.

When the gate 11 is closed, the switch 8a outputs the signal Mc1 output from the user intention reading device 7 as a motor control signal Mc. When the gate 11 opens, 0 is supplied as the signal Mc1.

The user intention reading device 7 controls the position by a control amount,
The control operation in which the proportional operation and the integration operation are combined in parallel is performed with ΔX = 0 as the target value. When the user 10 starts traveling, first, the speed command value Pv due to the proportional operation increases, and later, the speed command value Ps due to the integration operation increases. At the beginning of traveling, the proportional operation control system including the amplifier 7b of the user intention reading device 7 mainly works, and after a lapse of time, the speed command value Pv gradually decreases and the acceleration command value Ps becomes larger. .

In a steady state in which the user 10 is traveling at a substantially constant speed, an integration operation control system including an amplifier 7a and an integrator 7c mainly works. In the steady state, the position deviation ΔX becomes 0, and is maintained at the steady speed. In this way, control following the traveling speed Vh is performed.

With the control being performed as described above,
It is assumed that the user 10 has reduced the speed of the previous exercise due to sudden muscle abnormalities, loss of running intention, stumbling, or the like. Due to the movement of the endless track belt 1, the user 10 starts to fall backward on the movable surface, and the positional deviation ΔX becomes negative.
The speed of the motor 5 is reduced by the distance measuring device 8 that has detected the position of the user 10. If the speed of the motor 5 is smaller than the speed of the user 10, the user 10 moves backward. Is washed away. When the user 10 falls below the rear limit position, the motor 5 stops, but the user 10 may fall backward and hit the gate 11 due to inertia. However, the user 1
Since 0 is accepted, the damage to the user is small. Further, since the user 10 is received by the cushioning material 21 of the gate 11 and does not directly collide with the distance measuring device 8, it is possible to prevent the distance measuring device 8 from being damaged.

When the user 10 falls down on the endless track belt 1, no measurement target exists within the detection range of the distance measuring device 8, and the positional deviation ΔX becomes larger than the distance L. Therefore, the motor 5 is stopped. Even when the drive of the motor 5 cannot follow the sudden acceleration performed by the user 10 during the training and the user 10 exceeds the front limit line, that is, when the position deviation ΔX becomes larger than the distance L3 + the distance L5, the safety is maintained. Therefore, the motor 5 may be stopped.

When a person other than the user 10 has opened the gate 11 during the training of the user 10 or when the user 1
0 The gate lock lever 1
When the lock by 4 is released and the gate 11 is opened, since the distance measuring device 8 detects a user other than the user 10, the obtained positional deviation information is inaccurate and uses the incorrect positional deviation information. Thus, the user intention reading device 7 outputs the signal Mc1. However, in such a case, since the gate closing signals are not sent from the gate lock sensors 15 and 16, the switch 8a outputs 0 as the motor control signal Mc. Therefore, the motor driving device 6 can stop driving the motor 5.

As described above, according to the exercise training apparatus shown in FIGS. 1 to 3, the user 10 is stopped by the gate 11 even if the user 10 stops suddenly during use and the rotation of the motor 5 is delayed. The distance measuring device 8 can be protected and the distance measuring device 8 is not damaged because the user 10 does not directly contact the distance measuring device 8. When the gate 11 is not completely closed, the motor 5 does not rotate and the exercise training device cannot be used. The user 10 can use the vehicle only in a safe state by closing the gate 11.

In the exercise training apparatus shown in FIGS. 1 to 3, the control information display device 9 is provided with the acceleration of the movable surface determined by the user intention reading device 7 and the user's information obtained from the distance measuring device 8. The positional deviation △ X, information as to whether or not the distance measuring device 8 is at a regular position, information as to whether or not the gate has been closed, and the like may be displayed in, for example, a bar graph on a CRT, characters, a warning button display, or the like. . The user can visually confirm that the acceleration / deceleration of travel has been accurately detected and that the control system is working properly and that the user has not moved in a manner different from the user's intention. Can be adjusted, and it is possible to exercise safely and comfortably.

Other examples of the gate in the exercise training apparatus shown in FIGS. 1 to 3 as described above are shown in FIGS. 4 to 7, and will be described in order below.

In FIG. 4, instead of the gate 11 in the exercise training apparatus shown in FIGS. 1 to 3, a rotating column 22 is rotatably provided on the column 13, and a sensor support 23 connected to the rotating column 22 is a distance measuring device. 8 is supported.

As shown by the dotted line in FIG. 4, when the user 10 enters and exits the endless track belt 1, the sensor support 23 can be opened and closed, and when the user 10 is trained, the sensor support 23 is located at the position shown by the solid line. ing.

FIG. 5 is a schematic enlarged side view of a contact portion between the column 13 and the rotating column 22. FIG. 5A shows a state in which the distance measuring device 8 is located at the position shown by the solid line in FIG.
FIG. 5B shows a state in which it is located at the position shown by the dotted line.

First, a mechanism for determining that the distance measuring device 8 is at a regular position will be described. As shown in FIG. 5A, a member 24 is provided on the rotating column 22, and the member 24 projects into the column 13. A sensor 25 composed of a light emitting element 25a and a light receiving element 25b is provided on the support 13 above and below the member 24 protruding into the support 13,
When the light from the light emitting element 25a is blocked by the member 24, the sensor 25 is turned off, and the endless track belt 1 is driven. On the other hand, as shown in FIG.
Is rotated and is not at the proper position, the rotating support 22 rotates and the member 24 also rotates and moves out of the optical path. Since the light from the light emitting element 25a impinges on the light receiving element 25b and the sensor 25 is turned on, it is determined that the distance measuring device 8 is not at the proper position, and the endless track belt 1 is not driven.

That is, when the user 10 suddenly stops during the training, the speed of the endless track belt 1 cannot follow the movement of the user 10 or the rotation of the endless track belt 1 stops due to the malfunction of the distance measuring device 8. Instead, even if the user 10 is carried backward by the endless track belt 1 and collides with the distance measuring device 8 when it falls down, the rotating support 22 rotates and the distance measuring device 8 retreats in the direction in which the collision force acts. Therefore, it is possible to prevent the user 10 from colliding with the distance measuring device 8 and damaging the distance measuring device 8, and it is possible to reduce injuries when the user 10 collides with the distance measuring device 8.

When the distance measuring device 8 is not at the proper position during training or at the start of training, the endless track belt 1 is not driven. Therefore, the user 10 can safely operate only when the distance measuring device 8 is at the proper position. Training can be performed.

In the exercise training apparatus shown in FIG. 1, a fixed table, a mat, and the like provided in the exercise training apparatus are provided, and even if the user 10 falls down from the endless track belt 1, the user 10 gets on the fixed table or falls down on the mat. Can also reduce injuries caused by falls.

As shown in FIGS. 5A and 5B,
A mechanism will be described in which the rotating column 22 does not rotate due to the vibration generated by the movement of the user 10 but rotates only when it collides with the distance measuring device 8. The rotating column 22 is provided with a plurality of arc-shaped depressions, and the column 13 is provided with a fixing member 26.

FIG. 6 is a sectional view taken along the line AA of FIG. 5A, which will be described in detail below. Adjustment screw 27 on fixing member 26
A spring fixing plate 28 is provided at the tip of the adjusting screw 27.
Is provided. The spring fixing plate 28 holds one end of an expansion spring 29, and a ball 30 is provided at the other end of the expansion spring 29. The ball 30 can move in the left-right direction in the drawing against or according to the elastic force of the spring 29. The ball 30 is pressed into the hollow of the rotating column 22.

The ball 30 is also held by a support shaft 31. The support shaft 31 includes a spring fixing plate 28 and a fixing member 26.
6 is held by the fixing member 32 to such an extent that it can be slightly moved in the vertical direction in FIG. When the sensor support 23 that holds the distance measuring device 8 (not shown) is pushed and tries to rotate in the direction of the arrow of the rotating column 22, the ball 30 that is in contact with one of the depressions of the rotating column 22 is rotated by the rotating column 22.
Moves slightly downward in the drawing. At this time, since the contact surface is a slope descending right, the ball 30 receives a leftward force.

The compression of the expansion spring 29 causes the ball 30 to move leftward in the drawing. Since the movement of the ball 30 in the vertical direction in the drawing is restricted by the support shaft 31, the ball 30 gets over the depression of the rotary support 22 by the movement in the horizontal direction. The contact point of the ball 30 changes to the upper part of the arc of the depression of the rotary support 22 (on the drawing), and moves against the outer periphery of the rotary support 22 while moving only in the left direction on the drawing against the pressing force of the expansion spring 29. Touch Further, when the rotation support 22 rotates and reaches another depression, the ball 30 falls into another depression of the rotation support 22 by the operation of the expansion spring 29. This state is shown in FIG.
It becomes the position shown in.

The rotating column 22, ie, the sensor support 23
Adjustment of the magnitude of the external force (= door closing force) until the start of rotation of the sensor support 23, in other words, the magnitude of the collision force with which the sensor support 23 retreats, is determined by the distance between the fixing member 26 and the spring support plate 28 by the adjustment screw 27. Can be adjusted or by changing the spring 29 itself.

That is, in FIG. 6, when the rotating column 22 rotates due to vibration or the like generated during training of the user 10, the adjusting screw 27 is tightened to compress the spring 29 to shorten its length. By performing such adjustment, the spring constant K increases, and the force F = Kx required for the ball 30 to move from the depression of the rotary support 22a to the outer periphery increases. Here, x indicates the amount of contraction of the spring 29 required for the ball 30 to come out of the outer periphery of the rotating support 22a. Further, the spring 29 itself may be changed to one having a large spring constant K.

When a collision force equal to or more than the door closing force given in advance is applied, the rotating column 22 starts rotating. For example, the closing force is determined by the user's age, weight, gender, etc., so that the length of the spring 29 can be adjusted or the type of the spring can be changed according to the use situation.

The mechanism shown in FIG. 6 may be replaced with the mechanism shown in FIG. 7 as a mechanism for stopping the rotation of the rotating column 22 so that the rotating column 22 is not rotated by the vibration generated when the user 10 moves.

In FIG. 7, a sensor support 23 for holding a distance measuring device 8 (not shown) is held on a rotating column 22a. The fixed part 40 provided inside the column 13 has a spring 4
1 is fixed, and the other end of the spring 41 is
Is fixed to one end of an L-shaped portion of an L-shaped movable portion 42 provided in the inside. The movable portion 42 is held on the support 13 with the L-shaped corner as the center of rotation, and the other end of the L-shaped portion of the movable portion 42 is in contact with a projection 43 provided on the rotary support 22a.

FIG. 7A shows a state in which the distance measuring device 8 is arranged at a regular position, and FIG. 7B shows a state in which the rotary support 22a rotates in the direction of the arrow.

That is, as shown in FIG. 7 (a), the projection 43 fixedly provided on the rotary support 22a does not contact the L-shaped movable portion 42 at a regular position, or contacts the L-shaped movable portion 42 very lightly. When the rotating column 22a rotates, the other end of the L-shaped portion of the movable portion 42 is pushed downward as shown in FIG. 7B.
That is, the lower support point of the spring 41 shifts to the right from the position where the upper and lower support points of the spring 41 and the rotation center of the movable section 42 are on a straight line, so that the spring 41 generates a force for rotating the movable section 42 to the left. When the rotational force of the rotating column 22a is smaller than a predetermined value, the spring 41 expands, and the force for rotating the movable portion 42 counterclockwise increases, and the rotation is balanced at a certain rotation angle. In this state, the projection 43 is in contact with the movable part 42. When the rotational force of the rotating column 22a increases beyond a certain value, the projection 43 moves beyond the tip of the movable portion 42, and the rotating column 22a loses its binding force and rotates.

In order to return the rotary support 22a to the original state, the rotary support 22a may be manually rotated in the direction opposite to the arrow. The movable portion 42 has returned to the state shown in FIG. 7A.
3 make contact. Further, when the rotating support 22a is rotated in the direction opposite to the arrow, the projection 43 pushes the outside of the lower side of the L-shape of the movable part 42, and the lower fulcrum of the spring 41 shifts to the left. It can enter the inside of the lower side of the character (the position shown in FIG. 7A) and return to the original state. Note that a mechanism for rotating the rotating column 22a in the direction opposite to the arrow may be provided, and the user may automatically return to the original state by pressing a switch.

As described with reference to FIG. 4 to FIG.
0 drives the endless track belt 1 when the distance measuring device 8 is disposed at a regular position and the output from the photoelectric sensor 25 is detected. The operation in the normal state and the control of the endless track belt in the abnormal state are the same as those in the embodiment shown in FIGS. Even if the user 10 collides with the distance measuring device 8, the rotating struts 22 and 22 a rotate, and the collision force transmitted directly to the distance measuring device 8 can be dispersed to some extent, so that the distance measuring device 8 is damaged. In addition, the impact force received by the user 10 due to the collision can be minimized. Further, by changing the spring constants of the springs 29 and 41 according to the age, gender, weight, etc. of the user, the vibrations generated when the user 10 exercises do not open and the collision of the user 10 or the endless orbital belt 1 does not open. It can be opened with the force of opening and closing when ascending and descending.

As a means for judging that the distance measuring device 8 is located at a regular position, the photoelectric sensor 25 is not used, and the recess of the rotary support 22 shown in FIG. 6 or the rotary support 22a shown in FIG. A pressure sensor or the like is provided on the projection 43,
While detecting the output from the pressure sensor, the distance measuring device 8
May be determined to be located at the regular position.

Also, in the exercise training apparatus shown in FIGS. 1 to 3, the gate 11 is not fixed by the gate lock lever 14 (in place of the gate lock sensors 15 and 16). The gate 11 is opened when the user 10 collides with the cushioning material 21 and the impact received by the user 10 at the time of the collision can be reduced by substituting the same structure as the rotation column 22 or the rotation column 22a or the rotation column 22a.

[0057]

As described above, according to the present invention, the position deviation detecting means is held at a position near the end of the movable surface in the direction in which the movable surface moves by the driving means and at which the user does not directly touch. By providing the position deviation detecting means support device, it is possible to obtain an exercise training device which does not damage the position deviation detecting means even if the user collides with the position deviation detecting means supporting device.

Further, according to the present invention, when the user collides with the position deviation detecting means supporting device, the position deviation detecting means supporting device is provided with a retracting means in a direction in which the collision force acts. Even if the user collides with the position deviation detecting means support device, the impact force transmitted to the position deviation detecting means can be reduced, and the position deviation detecting means is not damaged,
It is possible to obtain an exercise training device that can reduce the impact force received from the position deviation detecting means when the user collides, and can reduce the injury to the user.
