DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. As shown in Figs. 1 and 2, a substantially rectangular body frame 1 having a predetermined length and width is provided with a substantially U shape on both front left and right sides.
A handrail part 2 made of a V-shaped pipe is erected, and a substantially U-shaped leg stand part 3 is similarly connected to the left and right sides of the rear part so that the main body frame 1 can be horizontally held at a predetermined height from a floor surface F. A drive unit 4 is provided in front of the handrail unit 2, and an endless running belt 5 that is rotated by the drive unit 4 is rotatably supported by the drum 6 at the front and rear ends of the main body frame 1.
(Refer to FIG. 3), it is wound around 7.

As shown in FIG. 3, the drive portion 4 is a U-shaped engagement which is fitted to both ends of a shaft 8 on which the drum 6 is rotatably supported, on both left and right sides of the front end surface of the main body frame 1. The part 9 (see FIG. 5) is mounted on the front frame 10 having a predetermined width and length on both left and right sides of one end, and is covered with a cover 11. As shown in FIGS. 3 and 4, a first drive source 12 composed of an electric motor is fixed inside the cover 11, and an endless belt 15 is wound around a pulley 14 attached to an output shaft 13 thereof. A pulley 16 is wound around the belt 15 together. The pulley 16 is mounted on the shaft 8.

A substantially triangular base plate 17 is rotatably supported on both ends of the front frame 10 so as to rotatably support rollers 18, and a shaft 19 is connected to the base plate 17. (See Figure 6). As shown in FIGS. 5 and 6, a sprocket 20 is rotatably attached to one end of a shaft 19, and an endless chain 21 is wound around the sprocket 20. The endless chain 21 is a second gear from a geared motor fixed to a base plate 17. It is wound around the output vehicle 22 of the drive source 23.
The other end of the shaft 19 is screwed into a nut 24 as a screw shaft, and the nut 24 is fixed to a tube 25. As shown in FIGS.
Is connected swingably, and the rod 26 extends in the rear end of the body frame 1 and is connected in a T-shape to a rod 28 rotatably supported between the leg bases 3 so as to extend and retract. I am configuring.

Further, as shown in FIG. 3, the front frame 10 has an operation panel 29 (see FIG. 2) in which drive control of the drive source 12 and the second drive source 23 is mounted on the handrail portion 2.
A controller 28 for controlling with the operation buttons 30 is mounted. As shown in FIG. 1, the operation panel 29 is fixed to the uppermost part of the handrail part 2 with a slight inclination, and as shown in FIG. 2, a large number of operation buttons 30 are arranged on the board surface. The operation buttons 30 are "angle up", "angle down", "start speed is faster", and "speed is maintained" in order from the top.
There are 6 buttons, "slow speed" and "stop speed", and an electric display section 3 for confirming these.
1 is provided.

Therefore, when the running practitioner wants to adjust the tilt angle of the frame 1 in advance during practice, he or she pushes the operation button 30 of "angle up" or "angle down", and the second drive source 23 is turned on. When the sprocket 22 is driven to rotate the endless chain 21, the sprocket 20 is rotated to rotate the shaft 19 in either forward or reverse directions. It undulates around the shaft 8 with which the joints 9, 9 engage. Therefore, as shown in FIG. 7, since the main body frame 1 and the front frame 10 move up and down from the floor surface F around the shaft 8, the inclination angle of the main body frame 1 can be changed to an angle suitable for itself. That is, the operation button 3 for "angle up"
When 0 is pressed, the tilt angle of the body frame 1 rises,
When the operation button 30 for "decrease the angle" is pressed, the inclination angle of the main body frame 1 decreases.

After the setting of the inclination angle of the main body frame 1 is completed, the running practitioner rides on the running belt 5, holds the handrail part 2, and pushes the "start speed fast" operation button 30 with one hand, Drive source 12 drives shaft 1
3 rotates, the endless belt 15 rotates via the pulley 14, and the shaft 8 rotates via the pulley 16 to rotate the drum 6, which in turn rotates the running belt 5. Can run on the running belt 5.

When it is desired to increase the traveling speed,
By further pressing the operation button 30 that was pressed first, the rotation speed of the drive source 12 gradually increases. Therefore, when the operation button 30 of "Keep speed" is pressed when the desired speed is reached, that speed is maintained. It This speed increase is done in stages, from a speed of 4 km per hour to a speed of 16 km per hour.
It is set to rise step by step.

Further, when the speed started by the operation button 30 initially pressed is suitable for the user in the middle, the speed is maintained by pressing the "keep speed" operation button 30. If you want to slow down the speed, press the "Slow" operation button 30 to gradually reduce the speed.
When the "keep" operation button 30 is pressed, the speed is maintained. And when you stop the practice, "Stop"
By pressing the operation button 30 of 1, the driving of the drive source 12 is stopped and the rotation of the traveling belt 5 is stopped.

An optical sensor 32 is provided as shown in FIG. 2 in order to prevent the practitioner from being unable to keep up with the rotational speed of the running belt 5 and gradually coming out of the running belt 5 with a delay. This optical sensor 32 is the operation panel 2
As shown in FIG. 8, it has a light emitting element 34 which emits a predetermined light beam through a lens 33 and a light receiving element 36 which receives a reflected light ray reflected from a trainee through a lens 35 as shown in FIG. When the practitioner M is at the position of the detection distance L, the reflected light beam is arranged to be substantially at the center of the light receiving element 36, and the practitioner M is far (L
It is possible to judge whether it is in + ΔL) or in the vicinity (L-ΔL). As long as the practitioner M is in the running range 37, the lamp lights up. A warning sound is emitted, the lamp is extinguished, and the driving of the traveling belt 5 is stopped unless the traveling range 37 is returned within the predetermined traveling time. The proper traveling range 37 is indicated by a mark 38 (see FIG. 2) on the body frame 1.

When the traveling belt 5 is stopped, an error display is displayed on the operation display plate 28, and this error display is automatically canceled after a certain period of time. Alternatively, it is free to release it by pressing the reset switch. With respect to the electrical / electronic configuration for realizing these, it is possible to easily perform it without requiring any particular devising power in the present technical field, so the details of the configuration will be omitted.
