Abstract

PROBLEM TO BE SOLVED: To propose a device fitted with a shoe converting potential energy into spring energy and utilizing the force of a spring as the force for raising and putting forward a foot in an auxiliary way, as the potential energy at the time when a self-weight is applied by putting down the raised foot on the ground has been consumed wastefully without being utilized in conventional walking raising both feet alternately and putting the raised foot forward to move a body. SOLUTION: A plate spring 3 is installed at a tip part between an upper plate 1 and a lower plate 2. The central part in the vicinity of the end of the upper plate 1 and the center part in the vicinity of the end of the lower plate 2 are connected by a stopper 4 like a string and the like in such a manner that an angle formed between the upper plate 1 and the lower plate 2 shifts within an acute angle. The upside of the upper plate 1 is bonded with the front of a shoe 5. A self-weight is put on the shoe 5 to bend the plate spring 3, and spring energy accumulates. The accumulated spring energy is utilized as the force raising and putting forward the foot in an auxiliary way, so that footwork is lightened.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device that is worn on shoes that utilizes the potential energy during walking, which has been wasted, as an assisting force for walking, and reduces the carrying of the foot to increase the walking speed. Things.

[0002]

2. Description of the Related Art Hitherto, walking has been carried out with the right and left feet alternately put forward, and the potential energy when the foot is lifted and lowered on the ground and the weight is applied is wasted.

[0003]

When walking, the foot that goes forward moves away from the ground and reaches the ground again, temporarily storing the potential energy when applying its own weight as spring energy,
It is an object of the present invention to provide a walking device that can be effectively used as a propulsion force when the same foot is stepped forward again.

[0004]

A spring that opens and closes in an arc shape, such as a leaf spring or a torsion spring, is attached to the distal ends of the upper plate 1 and the lower plate 2. The upper plate 1 and the lower plate 2 are connected by a stopper 4 such as a string so that the angle formed by the upper plate 1 and the lower plate 2 changes within an acute angle. The front bottom of the shoe 5 is mounted on the upper surface of the upper plate 1. When walking, the springs that have been closed on the feet that move forward can open the feet lightly and quickly step forward.

[0005]

With the above construction, the stepping on the foot during walking becomes lighter, and the walking speed increases.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a leaf spring 3 or a spring which opens and closes in an arc shape, such as a torsion spring, is mounted between the upper plate 1 and the lower plate 2 at the end. Around the center of the upper plate 1 and the lower plate 2 is provided a stopper 4 such as a string for limiting an operation range so that the opening and closing operation is performed within an acute angle between the upper plate 1 and the lower plate 2. The angle formed by the lower plate 2 should not be more than 60 °. On the lower surface of the upper plate 1 and the lower plate 2, and on the portion in contact with the ground,
Attach non-slip rubber. The bottom of the shoe 5 is joined to the upper surface of the upper plate 1. Further, as a method for canceling the force of the spring, that is, a state similar to that of normal walking, a connecting rod guide 7 having a hole inside is provided on the lower surface of the upper plate 1 as shown in FIG. Also, on the upper surface of the lower plate 2, a lower connecting rod guide 8 having a hole inside is provided. The hole positions of the upper connecting rod guide 7 and the lower hole of the connecting rod guide 8 are set to positions where the connecting rod 6 can pass through both holes when the upper plate 1 and the lower plate 2 are close to contact. is there. The weight is put on the shoe 5, and the connecting rod 6 is slid while the upper plate 1 and the lower plate 2 are in close contact with each other, and the connecting rod 6 is connected to the hole of the upper connecting rod guide 7 and the lower connecting rod guide 8 as shown in FIG.
And fix it through the hole. This cancels the spring force. As a method of attaching the upper plate 1 to the bottom of the shoe 5,
The upper plate 1 is positioned in front of the bottom of the shoe 5 as shown in FIG. 6, and the front fixing device 9 such as a string is attached so as to be wound around the toe of the shoe 5. Then, the rear fixing device 10 such as a string on the left and right is attached so as to be hooked on the left and right near the upper of the shoe 5. Alternatively, the user connects the left and right sides and steps on the line of the fixing device 10 on the sole of the foot after the length is long enough to be stomped on the sole of the foot, and is attached.

[0007]

According to the present invention, when walking, the carrying of the foot is lightened, and the walking speed is increased.

Claims (1)

[Claims] As shown in FIG. 1, between the upper plate 1 and the lower plate 2, a distal end portion is opened and closed in an arc shape like a leaf spring 3 or a torsion spring, and a strong spring is mounted in the opening direction. The opening angle of the stopper 4 such as a string is limited so that the angle between the upper plate 1 and the lower plate 2 can be opened and closed within 0 ° to 60 °. The upper plate 1 of the elastic opening / closing plate having such a configuration, and the upper surface
Mounted on the bottom, front. When stationary, the upper plate 1 and the lower plate 2 are in a state close to contact, and the shoe sole maintains a state substantially parallel to the ground, and can maintain stability. Converts the potential energy during walking to spring energy and uses it as a force to raise the foot as an auxiliary and a force to put the foot forward, lightening the carrying of the foot and increasing the walking speed. A device that attaches to possible shoes.
