Issues that the device is trying to solve

  As described in the related art, the treadmill is used exclusively in a stationary state and includes a caster for moving an installation place, but none is used as a traveling means for passing.

  The present invention has been made in view of the above-mentioned problems of the prior art, and aims at equipping the treadmill with steering wheels and driving wheels at the front and rear of the frame and endlessly. A belt is driven by a maneuvering operation, a driving force is transmitted to a driving wheel via a transmission means, and a driving means for obtaining a propulsion force and a treadmill-type traveling vehicle used for both of a normal stationary treadmill and a vehicle are provided. Is what you do.

Means for solving the problem

  In order to achieve the above object, in the treadmill type traveling vehicle of the present invention, a steering wheel is attached to a lower part of a handle supported on a front position of a rectangular frame body, and an axle is mounted on a rear position and both sides are mounted. The drive wheel is stopped at the shaft end of the axle, and a toothed pulley equipped with a one-way clutch is fitted in the middle of the axle. A wide endless belt is wound between the two rolls in the frame of the vehicle body, and the center of the outer peripheral surface of the belt is attached in advance with the tooth profile of the toothed belt facing outward, and the back surface is attached. The toothed pulley is meshed with the tooth profile on the lower side of the toothed belt in a pressing manner, and the one-way clutch includes a cam clutch or a free wheel.

  In the above structure, the steered wheels are operated in the steering direction by the handle, and the upper side of the endless belt is driven rearward by a passenger's forcible operation to transmit the belt from the toothed belt to the toothed pulley. In this way, the one-way clutch in the pulley is set to an automatic wedge state to drive the axle and the driving wheel, and the vehicle travels with the propulsion force as a ground reaction force of the driving wheel tread surface, and stops the ascending operation to stop the vehicle body and the passenger. When the vehicle coasts due to the inertia of the total weight including the axle, the one-way clutch is released from the wedge state by the rotational force on the axle side, and the axle or the drive wheel idles.

  A substantially horizontal support rod is cantilevered at the base end of the vehicle body below the handle, and a horizontally long pad is supported at its free end in a T-shape. A reaction force toward the front of the passenger with respect to the driving force of the belt due to the row operation is received by buffering the pad.

  A stand is supported at a lower end of the rear end of the vehicle body at a base end position. When the vehicle body is moved, the stand is rotated above the ground and held, and when the stationary body is put into service, the stand is used. Is turned on the ground and supported in an upright manner.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the invention will be described with reference to the drawings based on an embodiment. Referring to FIGS. 1 to 5, a steering wheel 2 is attached to a lower portion of a handle 2a which is supported at a front position of a rectangular frame-shaped vehicle body 1, and Axle 3a is mounted on the shaft, drive wheels 3 and 3 are fixed to the shaft ends on both sides, and a toothed pulley 5 having a one-way clutch 4 is fitted in the middle of the axle. A front end roll 6 and a rear end roll 7 are mounted on the rear side of the axle, respectively, and a wide endless belt 8 is wound between the two rolls in the frame of the vehicle body. Is attached to the back surface 9b with the tooth profile 9a of the toothed belt 9 facing outward in advance, and the toothed pulley 5 is pressed and meshed with the tooth profile 9a on the lower side of the winding of the toothed belt. , The steering wheel is operated in the steering direction by the steering wheel, so that the passenger m Then, the upper side of the belt is driven backward to transmit the power from the toothed belt to the toothed pulley to drive the axle and the drive wheel with the one-way clutch in an automatic wedge state, thereby obtaining a propulsive force as a ground reaction force of the drive wheel tread surface. When the absent operation is interrupted and the vehicle is coasted by the inertia of the total weight including the vehicle body and the passenger, the one-way clutch is released from the wedge state and the axle or the drive wheel idles.

  The reaction force of the passenger m on the endless belt 8 against the belt driving force due to the ascending motion of the passenger m is large enough to be easily supported by the upper limb of the passenger m holding the handle 2a on a flat ground. However, when going uphill and performing rapid acceleration, a strong belt drive force is required due to a strong ascending operation, and the reaction force exceeds the supporting force of the passenger's upper limb, and the lower limb Since the total muscular force acts between the hip joint and the sole of the foot and receives a reaction force around the hip bone supporting the hip joint, the substantially horizontal support rod 10a is attached to the vehicle body 1 below the handle 2a. A cantilevered support is provided at the base end, and a horizontally long pad 10 is supported at the free end in a T-shape, and the pad is formed so as to abut on the hip or near the lumbar girdle.

  As shown in FIG. 1, a stand 11 is supported at a lower end of the rear end of the vehicle body 1 at a base position. When the vehicle body is moved, the stand is rotated above the ground and held. When the stand is used, the stand is turned on the ground to support the drive wheel tread while maintaining the ground clearance k.

  At the lower surface of the belt between the front roll 6 around which the endless belt 8 is wound and the rear roll 7, idle rollers 12, 12 are arranged at several places on the vehicle body 1 with a gap c from the lower surface of the belt. When the tread pressure moves due to the abutment operation on the belt without contact with the belt at all times, the idler roll and the belt come into contact only with the part where the tread pressure is received, and idle, and the driving resistance of the belt is reduced. To a minimum.

であって、走行速度Ｖは、数２により、

となり、徒行速度Ｌ／Ｓの２．５倍に相当する。Further, in the above configuration, as an example of setting the traveling speed, the stride length of the maneuvering operation on the endless belt, that is, the drive length L is 0.5 m, and the time required for one step S is 0.5 s, ie, Assuming that the pitching radius r of the toothed pulley 5 is 0.04 m and the driving wheel radius R is 0.1 m, the running speed L / S is 1 m / s, and the rotation speed n of the driving wheels is

And the traveling speed V is given by

Which is equivalent to 2.5 times the ascending speed L / S.

となり、走行速度Ｖは、数４により、

となり、徒行速度Ｌ／Ｓの３．３３倍に相当する。Further, in the above embodiment, in order to increase the running speed, for example, when the pitch circle radius r of the toothed pulley 5 is 0.03 m and the driving wheel radius R is 0.1 m, the rotation speed n of the driving wheel is set to n. According to Equation 3, the traveling speed V is

And the traveling speed V is

, Which is equivalent to 3.33 times the flight speed L / S.

When the total weight including the vehicle body and the passenger is 80 kg, the rolling resistance on a normal flat paved road is 1.6 to 2 kg, and on a paved road with an inclination angle of 5 degrees, the gradient resistance is In contrast, when the driving force of the endless belt by the apostle motion is 30 kg and the traveling speed is 2.5 to 3.33 m / s, the driving wheel propulsion force is approximately 2.5 to 3.3 kg / 30 kg. 3.33, that is, 12 to 9 kg, so that it is possible to travel on a paved road with an inclination angle of about 5 degrees, and the traveling speed V is low for elderly people and welfare equipment depending on the use conditions of the passenger. High-speed type specifications shall be set for type specifications, road traffic or sports use.

  Further, in order to use the treadmill type traveling vehicle having the above configuration for road traffic, it is necessary to complete the brake 2b, the saddle, and the headlight (not shown).

The effect of the invention

  Since the present invention is configured as described above, it has the following effects.

Power is transmitted to the one-way clutch, the clutch is in the automatic wedge locking state, the driving force is transmitted to the drive wheels, and the vehicle is running with the propulsive force as the ground reaction force of the drive wheel tread, and even if the absent operation is interrupted, Due to the inertia of the total weight including the vehicle body and the passenger, the coasting is continued for a while. At this time, the clutch is released from the wedge state by the rotational force on the axle side, the drive wheels freely rotate, and the coasting speed gradually decreases. In this case, the running state can be continuously maintained by repeating the apostle operation.

  According to a second aspect of the present invention, there is provided a treadmill-type traveling vehicle according to the first aspect, in which a pad supported on a vehicle body below the steering wheel buffers and receives a reaction force against a strong belt driving force, thereby rapidly accelerating. In addition, since the belt driving force and its reaction force can be small on a flat ground, the vehicle can be easily supported by the support force of the upper limb of the passenger and can travel without depending on the pad.

  The treadmill-type traveling vehicle according to claim 3, while the vehicle is moving or traveling, holds the stand by rotating above the ground, transports the stand to an arbitrary location on a road surface or a floor surface, and sets a timer and a distance. The stand is pivoted on the ground and supported in an upright position, and the steered wheels are braked and used in a stationary state. , And can be used for both stationary and stationary applications.

  Treadmill-type traveling vehicles are suitable for both traveling and stationary use.The endless belt does not have a rotating projection like a rotary pedal such as a bicycle or a bicycle-type ergometer, and can safely drive. And can be used on roads, indoors and premises.

  In addition, the maneuvering operation on the endless belt is almost the same as the walking or running operation on a flat ground, and the upper surface of the belt is continuously driven rearward, and is used in a rotary pedal such as a bicycle or a bicycle ergometer. The inefficient return operation due to the pulling is not complicated, and the present invention can be used for an abduction training aiming at a normal abduction operation and a walking function recovery training in the field of welfare equipment.

  This endless belt, belt transmission or chain transmission, and a transmission system using a one-way clutch have a simple structure, and can be applied to a lightweight, small, and inexpensive treadmill-type traveling vehicle. Alternative mechanisms can be used.
