Both the running machine and the video walking machine control the advancing speed of the image according to the speed of the running floor or the walking belt, that is, the stepping speed. The speed is adjusted and regulated to a constant level, and then the pedal speed is made to follow the speed.

``Problems that the invention aims to solve'' In this invention, we have focused on the important arm swinging exercise, which is performed together with the stepping exercise and has the effect of encouraging and promoting the stepping exercise, and can be expected to have even more exercise effects. , the product of the velocity and amplitude of the arm swing motion,
Its momentum is stimulated through a pulley around which a traction rope is wound and rotated, and its rotation angle detector, thereby obtaining a pulse signal corresponding to the product of the speed and amplitude of the arm swing movement, which is used to control the projection device. It is a stepping exercise machine equipped with a projection device that controls and drives the recording tape placed on the screen and synchronously reproduces the recorded scenery on the projection screen.The machine is made to consciously move the arms as well as the legs. It is an object of the present invention to provide an exercise machine that allows the user to exercise the whole body with interest by training the whole body and gaining a practical sensation of movement, thereby further enhancing the effect of the exercise.

``Means for solving the problem'' As a means to solve the above problem, the step stool is used as a belt conveyor type platform, and by stepping on the running belt, Bernat is kicked backwards while swinging both arms back and forth. In order to be able to grasp both ends of the tow rope with both hands and pull the rope back and forth alternately, the pulleys are mounted horizontally on both sides of the drive device, which is installed along with the projection device at the rear of the footstool. The rope is continuously wound and stretched, and a rotation angle detector is connected to one of the pulleys to obtain a pulse signal corresponding to the product of the speed and amplitude of the arm swing motion, and a pulse signal of the reverse rotation of the signal is obtained. The speed of the drive motor for the recording tape is controlled by passing it through an inverting circuit and adding it to the counter, thereby making it possible to synchronously reproduce the recorded scenery on the projection screen. Road scenes taken continuously at a constant speed are recorded magnetically, and this is attached to the video deck of the projection device, and the road scenery is projected onto the projection surface in response to the arm swing movements made with foot stepping. This is an exercise machine that allows you to experience a realistic feeling of walking or running.

``Function'' By grasping both ends of the towing rope continuously wound around both left and right pulleys with both hands and pulling it alternately from left to right, both pulleys repeat alternating rotations in the forward and reverse directions. Therefore, a forward/reverse rotation signal can also be obtained from the rotation angle detector coaxially connected to one of the pulleys, but by inverting the rotation signal from one side using an inverting circuit and applying it to the next counter circuit, recording can be performed. This signal is used as a control signal for the tape drive motor, thereby driving the recording tape and synchronously reproducing the recorded scene on the projection screen.

``Embodiment'' The structure of an embodiment of the present invention will be explained along with its operation with reference to the attached drawings.

FIG. 1 is a perspective view showing the overall appearance of the exercise machine of this embodiment. A footrest 1 serving as an exercise base includes free rollers 2 at both front and rear ends installed in parallel between left and right frames 1a, 1a. It is a belt conveyor type stand in which an endless running belt 4 is wrapped around the upper and lower surfaces of 2 and auxiliary rollers 3 arranged in an appropriate number in the middle part, and a CRT display 5 and a video deck 6 are installed as projection devices at the rear of this stand. and a machine room 7 in which a drive device is housed in the lower part thereof, and both ends of the traction rope 8 wound around the drive device in the machine room protrude forward from both left and right sides of the machine room. A gripping rod 8a is attached to the front end of the rope, and by gripping both gripping rods with both hands and pulling them alternately to the left and right according to the arm swing motion performed in conjunction with the stepping motion, the rope is operated by the mechanism of the drive device described later. It is designed to operate the projection device.

Further, in the video deck of the projection device, a recording tape recording road scenes continuously photographed outdoors is inserted in advance into the insertion slot 6a, and the recording tape is moved to the arm swinging motion via a drive device. It is designed to be driven accordingly and project moving scenery on a CRT display. In addition, 9 in the figure is the altitude adjustment handle of the drive device and projection device, and 10
11 is a power switch, 12 is a pilot lamp flashing button, 13 is a start/stop button, 14 is a support shaft, 15 is a support leg, 16 is a support bearing, 17 and 18 are It is an anti-vibration table.

Next, the mechanism of the drive device will be explained. FIG. 2 is a plan view of the drive device, and FIG. 3 is a front view thereof.
2 are installed opposite each other, and husband pulleys 23 and 2 are installed above both shafts.
3 is pivotally attached by keys 21a and 22a. A rotation angle detector 26 is connected to the lower end of the vertical shaft 22 via a coupling 24 and is fixed to the bottom surface of the substrate 20 by a fixing metal fitting 25. Further, both ends of the towing rope 8 continuously wound around both the left and right pulleys 23, 23 extend forward through the husband rope guides 27, 27, and the front end is connected to a grip bar 8a. By alternately pulling the pulley 23 on the left and right sides, the rotation angle detector 26 rotates alternately in the left and right directions together with the pulley 23 on one side (the right side) to emit control pulses, and the recording tape is driven by the control pulses.

The electric circuit from the rotation angle detector 26 to the recording tape drive motor 37 will be explained with reference to the block diagram shown in FIG.

Both forward and reverse rotation signals, a right rotation signal r and a left rotation signal l, are obtained from the rotation angle detector 26, and among both signals, the left rotation signal l is inverted by an inverting circuit 31 and applied to the next stage counter 32. This is used as a control signal for the counter. On the other hand, the counter circuit 32
A clock pulse is inputted from the oscillator 33, and is controlled and counted by the control signal of the counter. The counted pulses are converted into analog quantities by the D/A converter 34 at the next stage. This outputs a DC voltage that controls and drives a recording tape drive motor 37 through a driver circuit 36 via a CR time constant circuit 35 for preventing flickering of images.

Therefore, it is possible to synchronously reproduce scenes recorded on a recording tape that have been photographed and recorded in advance at a progressing speed corresponding to the speed and amplitude of the arm swinging motion.

In addition, a CR time constant circuit is installed in the middle of the video to ensure smooth progression of the video so that the video does not flicker even when the arm swing motion changes rapidly.

Next, the height adjustment device for the drive device and the projection device, and the inclination angle adjustment device for the footstool, the drive device, and the projection device will be explained.

FIG. 5 is a longitudinal cross-sectional view of the device, and FIG. 6 is a cross-sectional view of the device.
0, 40, and front and rear lower links 42, 42 loosely connected thereto by pins 41, 41, and the other ends of both links are connected via husband connecting rods 43, 43 to husband upper links 42', 42'. connected to the upper link 42',
The other end of 42' is connected to the connecting plate 44 by playing with the husband pins 41', 41'. These members constitute a set of pantograph mechanisms. Furthermore, all of the driving devices and projection devices to be adjusted are connected to a housing (not shown) that is connected to a worm wheel 45 that is engaged with a connecting plate 44.

Further, the front end support parts of the height adjustment shaft 46 and the inclination angle adjustment shaft 47 respectively pass through the connecting rod 43 and constitute shaft bearing parts 43a and 43b that can rotate freely, and a height adjustment handle 9 is provided on the front end surface of both shafts. and the inclination angle adjustment handle 10 are press-fitted, and the rear end of both shafts is provided with a thread 46a in the former, and a threaded portion 43c of the connecting rod 43 is inserted.
In the latter case, a round shaft with a keyway 47a cut therethrough is loosely inserted into the insertion hole 43d of the connecting rod 43.

When adjusting the height of the drive device and projection device, turning the height adjustment handle 9 left and right moves the connecting rod 43 screwed into the height adjustment shaft 46 back and forth, and moves the pantograph mechanism up and down. A driving device and a projection device connected to the casing coupled to the worm wheel 45 engaged with the upper portion thereof move up and down.

Also, when adjusting the inclination angle of the footstool, drive device, and projection device, it is necessary to change the inclination of the footstool so that it is easier to kick the belt on the footstool backwards, and to adjust the inclination angle of the footstool and the drive device on the step. This is to ensure proper posture of the device and the projection device. In that case, when the tilt angle adjustment handle 10 is turned, the tilt angle adjustment shaft 47 rotates, and the worm 4 is attached to the shaft.
8 is fitted through a key 48a, and a worm wheel 49 meshed with the worm and a support shaft 14 fitted onto its shaft through a key 14a rotate. Therefore, the threaded portion 1 carved in the lower part of the support shaft 14
4b and the nut 50 screwed thereon and installed between the left and right frames 1a, 1a, the distance between the nut 50 and the support bearing 16 changes, and the angle between the footrest and the vibration isolator 17 is tilted. I will do it. or,
When the support shaft 14 rotates, the worm 51 fitted above it through the key 51a also rotates, and the worm wheel 45 meshed with it also rotates, and the worm wheel 45, which is connected to the casing connected to the worm wheel 45, also rotates. Since the projection device also tilts in conjunction with the step, the projection device tilts in the opposite direction at the same time as the footstool tilts, ensuring an appropriate posture.

``Effect of the invention'' In the foot exercise machine of the present invention, by swinging both arms back and forth while stepping, the pulley is rotated via the rope, and the rotation angle detector is used to prompt the degree of rotation of the pulley. We obtained a pulse signal corresponding to the product of the speed and amplitude of the movement, used that signal to drive the recording tape, and synchronously played it back on the recording screen, so the scenery changed according to the state of the arm swing movement. Because of this, even though you are exercising at a fixed position on a footstool, you can feel as if you are running outdoors, giving you the feeling of outdoor exercise in monotonous indoor exercise, and increasing interest and encouragement in your exercise activities. It can increase the effect of exercise.

In addition, by consciously performing arm-swinging exercises along with foot-stepping exercises, the exercise is performed as a whole-body exercise, which promotes blood circulation throughout the body and contributes to improved health.

Furthermore, since the recording tape is driven by a pulse signal that corresponds to the product of the speed and amplitude of the arm swinging motion, the progress speed of the image changes in accordance with the slowness and strength of the arm swinging motion, so the exerciser can By watching the progress of the video, I became more interested in the arm swinging exercise, and started waving my arms vigorously, which in turn encouraged me to do the stepping exercise, burning up my energy for whole-body exercise, and increasing the effectiveness of the exercise. It becomes even more exciting and you can train your whole body.

Moreover, compared to the system in which the recording tape is controlled and driven by rotating a roller by running a belt by stepping on it and converting the rotation into a pulse signal, it provides a much more practical feeling and a strong sense of interest.

In addition, at the connection between the footrest and the drive device, a height adjustment device for the drive device and projection device and a tilt angle adjustment device for the footstool, drive device, and projection device are provided, making it easy to kick the belt when stepping. The inclination angle of the platform can be adjusted, and the posture of the projection device etc. can also be adjusted automatically, and the height between the rope and the projection surface can be adjusted according to the height of the athlete. To provide an exercise machine that can be freely adjusted so that the exercise machine can be adjusted to a state suitable for use, and is easy for anyone to use regardless of the size of their physique.
