  The string 140 provided in the traveling tool Y is a direction in which the traveling tool Y is advanced by the rotational force of the drive shaft 21a when the string 140 is pulled out from the wheel 150 constituting the rotating body B. In the illustrated example, the string-like body 140 is pulled out from the lower side of the wheel 150 toward the rear upper portion of the traveling tool Y in the traveling direction.

  In addition, the spring 160 such as a mainspring spring mounted on the drive shaft 21a is tightened by the rotation of the drive shaft 21a rotated by the pulling-out operation from the wheel 150 of the wound string-like body 140. The urging force toward the loosening direction is stored.

  In the traveling tool Y, the string-like body 140 is always pulled in the direction of being caught in the wheel 150 by the urging force of the spring 160 such as a mainspring spring, and functions in a direction in which the pulley 74 and the pulley 125 are brought closer to each other. To do. As a result, the string-like body 140 functions to lift the pulley 125 of the support rod 120 in the telescopic support tool 100 so as to move upward so as to approach the pulley 74, and accordingly, the support The rod 120 is moved upward while sliding the circular hole 113a, the main support 40 is rotated upward with the shaft 43 as a fulcrum, and the guide rod 60 provided in the connecting piece 50 is gradually raised. Each guide means A, such as setting the state, moves the tread plate body 90 away from the traveling frame body 10 in a substantially parallel state while being associated with each other.

  The pulling up of the tread plate 90 by the string-like body 140 is applied to the main support 40, the telescopic support 100, the guide rod 60 and the receiving portion 113 of the lower support 110 connected by the connecting piece 50. Stopped at the end of 120 shaft base portion 122, etc., and as shown in FIGS. 4 and 5, the tread plate body 90 is raised above the traveling frame body 10 so as to be substantially parallel to the traveling frame body 10. Hold it in a state.

  In this state, a load is applied to the tread plate body 90 in the one running tool Y attached to the foot portion substantially in the middle of the tread plate body 90 against the urging by the spring 160 such as the mainspring spring. In addition, the tread plate body 90 is gradually pushed down toward the traveling frame body 10 by the guide means A while maintaining substantially parallel by being pushed slightly diagonally forward, and the lower support tool of the telescopic support tool 100 110, the pulley 125 of the support rod 120 inserted through the circular hole 113a is moved downward, and a space between the pulley 125 and the pulley 74 and the pulley 114 is opened, and the string that has been wound around the wheel 150 is formed. The body 140 is pulled out against the bias of the spring 160 such as a mainspring spring, and the wheel 150 and the drive shaft 21a are forcibly rotated.

  The rotation of the drive shaft 21a against the bias of the spring 160 such as a mainspring spring is transmitted to the front wheel 20a via the one-way rotational force transmitting means 130 such as a one-way clutch, and the traveling tool Y is advanced.

  After the tread board 90 is brought close to the traveling frame body 10 by the pushing operation of the tread board 90, the load is moved to the running tool Y mounted on the other foot side, and the tread board 90 is pushed. Pull up to release the pushing load on the side running tool Y.

  In this way, when the biped walking is lifted so as to release the pushing load applied to the loaded running tool Y, the raised running tool Y has the string-like body 140 associated with the pushing against the tread board 90. The drive shaft 21 a is rotated so that the spring 160 such as the mainspring spring accumulated by the pulling is repelled in the loosening direction and the string 140 is wound around the wheel 150.

  As a result, the string-like body 140 is drawn into the wheel 150 in a direction in which the pulley 74, the pulley 114, and the pulley 125 are brought closer to each other, thereby raising the tread plate 90 upward and returning to the state before the push-in.

  Such a traveling tool Y is provided with a mounting belt 94 inserted and prepared in a slit 93 provided in each tread plate body 90 so that the length can be adjusted so that the traveling tool Y can be conveniently mounted on the foot of the user. A belt 94 can be used on each foot.

The running fastener Y can be attached to the foot portion without loosening by hooking surface fasteners between the winding belts.

  The mounting of the traveling tool Y on the foot may be in any form as long as the mounting tool can be mounted on the foot. For example, the tread plate 90 is replaced with the mounting belt. Even if it is made into shoes or sandals for wearing itself, and this is worn directly on the foot, the worn shoes are attached to the tread plate 90 with belts, strings, metal fittings, etc. There may be.

  Further, the traveling tool Y is so-called by sequentially repeating the lifting of the foot with respect to the other traveling tool Y when the traveling tool Y is pushed into one of the traveling tools Y similar to the roller skate while being mounted on both feet. It can be used for easy and smooth running by a bipedal running operation.

  Further, in the traveling tool Y according to this illustrated example, the load is moved to the rear side in the traveling direction of the tread plate 90, for example, from the shaft 36 of the base frame 30 by moving the load as shown in FIGS. By rotating the rear side in the running direction downward with the shaft 36 as a fulcrum, the sliding contact control piece 35 on the rear side in the running direction of the base frame 30 is appropriately slid on the peripheral surface of the rear wheel 20b with a required pressure. The necessary amount of braking can be applied. Such a braking operation is performed by appropriately changing the load position on the traveling tool Y in the front-rear direction in the traveling direction at an arbitrary pushing position with respect to the traveling tool Y, so that the base located on the rear side in the traveling direction from the shaft 36. The amount of pushing of the frame 30 on the rear end side in the traveling direction can be increased or decreased, and the vehicle can travel while freely adjusting the traveling speed.

  When an emergency stop is required, as shown in FIGS. 11 and 12, the braking plate portion 14a of the braking plate 14 on the rear side in the traveling direction of the traveling tool Y is grounded. By pushing the tread plate 90 so that the traveling tool Y stands up in an inclined state, the braking plate portion 14a hits the lower surface of the lower inner collar 13b of the rear frame plate 13 with the shaft 14c as a fulcrum and the rear side in the traveling direction. In this state, the running tool Y can be urgently stopped by being grounded.

  Further, as the shaft 14c of the brake plate 14 is turned as a fulcrum, the elastic stopper piece 15b of the leaf spring 15 is brought into its upright state by the upright plate portion 14b of the brake plate 14 as shown in FIG. Then, it is tilted forward in the traveling direction against the urging of the leaf spring 15, is brought into contact with a hooking portion 95 provided in the footplate body 90, and the rear end side in the traveling direction of the braking plate 14 is grounded. In this state, the tread plate 90 can be returned slightly upward in the running direction with the shaft 36 as a fulcrum, and the elastic stopper piece 15b can be hooked on the hook portion 95 as shown in FIG. As shown in FIG. 13, the traveling tool Y is stored by hooking the elastic stopper piece 15b of the traveling frame body 10 to the hooking portion 95 of the traveling frame body 90 in a state where the footboard body 90 is close to the traveling frame body 10. And can be kept in a convenient state for carrying.

  The traveling tool Y in the state of FIG. 13 is grounded on each traveling wheel 20 and stepped on the tread plate body 90 and pushed downward as needed, so that the hooking portion 95 is made of the elastic stopper piece 15b. The elastic stopper piece 15b is released from its hooked state and is elastically restored so as to come into contact with the upright plate portion 14b. The tread plate 90 is attached to the spring 160 such as the mainspring spring. It is moved to move away from the traveling frame body 10 and can be subjected to the above-described method, that is, the traveling operation of pushing and pulling up sequentially in the form of a roller skate with respect to each traveling tool Y attached to the foot.

  The elastic stopper piece 15b used here travels by an upright plate portion 14b that is rotated toward the front side in the traveling direction with the shaft 14c as a fulcrum accompanying the grounding of the braking plate 14 on the rear end side in the traveling direction. When the tread plate body 90 is moved upward with the rear end side in the traveling direction of the brake plate 14 in the grounded state while being bent forward in the direction, the hooking portion 95 of the tread plate body 90 is As shown in FIG. 13, the state where each traveling wheel 20 is grounded and the movement toward the lower portion of the hook portion 95 due to the pressing toward the lower portion of the tread plate body 90 causes the hook portion 95 to be hooked.
