Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to skate shoes.

[0002]

2. Description of the Related Art Conventional skate shoes have bearings on all wheels that freely rotate in both forward and backward directions. (Fig. 6).

[0003] Since the sole portion of the shoe is hard and hardly deformed, it is impossible to flex and extend the metatarsophalangeal joint while wearing skating shoes.

[0004] Further, since the frame supporting the wheels is hard and does not deform, each wheel is always arranged in a straight line.

[0005]

A conventional skate obtains propulsion by a skating operation, that is, a sliding method of kicking diagonally backward and proceeding diagonally forward (FIG. 6).

[0006] In this method, there is a problem that the running distance is long because of the zigzag movement, and the distance is not efficient as compared with the linear moving method.

Further, there is a problem that a certain width is required for a runway for zigzag running.

Further, since this operation is a rare operation in daily life, it takes a considerable amount of time to learn the technique,
In addition, there is a problem that the load on the muscles and the respiratory circulatory system is large due to the recruitment of the undeveloped muscle group, and it is easy to be tired.

The present invention has various problems as described above in the conventional skating gliding method.
The purpose is to provide a skating shoe structure that can obtain a propulsion force by moving in a straight line (Fig. 7), similar to walking or running motion, that is, by protruding straight behind.

In the present invention, in order to further increase the propulsion,
The purpose of the present invention is to provide a structure of a skate that can obtain propulsion by using the tension of an elastic body.

[0011]

In order to achieve the above object, a skating shoe according to the present invention has a structure in which a frame supporting wheels is divided into a plurality of frames, and the plurality of frames are flexibly connected to each other. Among the plurality of frames, at least one of the front wheels supported by the frame including the leading edge includes at least the leading wheel, and is characterized by preventing reverse rotation.

Further, the skating shoe of the present invention is provided with a one-way clutch for preventing reverse running rotation.

Alternatively, when the frame supporting at least the leading wheel is bent, the brake mechanism acts on at least one including the leading wheel.

Adjacent frames are connected to each other by an elastic body, and the frames are arranged in a straight line in a normal state. When the frames are bent, a force is generated in a direction in which the frames return to the normal state due to a restoring force of the elastic body. The elastic body can be replaced according to the purpose.

The skating shoe is flexible or connected by an elastic body so that the skating shoe can bend at the metatarsophalangeal joint so that the frame can be bent.

A skating shoe characterized in that a bending prevention stopper is attached to a bent portion of the frame so that the frame is fixed in a normal state without bending depending on the purpose of running.

[0017] The skating shoe is characterized in that the mechanism for preventing the reverse running rotation is released for the purpose of running.

According to the above structure, the rear wheel can be lifted while the front wheel is in contact with the ground by bending the metatarsophalangeal joint. The posture can be controlled without difficulty.

Further, when the vehicle leans backward from this position, the rotation of the wheels is locked due to the operation of the reverse running prevention mechanism, and as a result, the driving force acts directly on the ground, which becomes the driving force for forward movement.

Further, by attaching a bending prevention stopper to the bent portion of the frame, the front and rear frames can be fixed in a normal state so as not to be bent. You can glide by skating action to get propulsion by.

The one-way clutch can be replaced according to the purpose, and can be provided with the same function as a conventional skate that can be retracted by installing bearings that freely rotate in both directions.

Japanese Patent Application Laid-Open No. 9-173525 discloses a skating shoe provided with an in-line type wheel in which a frame portion and a shoe portion can be bent and extended. In other words, it presupposes a zigzag-type sliding method. In this case, by allowing the frame to bend, it is possible to transmit force to the user in an optimal manner during thrusting, and correct movement that does not force the foot. The purpose of the present invention is to provide a skate shoe that can be used for running.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to FIGS. (First Embodiment) FIG. 1 is a side view of a skating shoe according to the present invention. Note that this figure shows the frame in a bent state. Figure 2 is a back view of the skates. The soles of the front bodies 2 and 16 and the rear bodies 3 and 17 are connected by a body connecting member 15, and the front bodies 2 and 16 bend and extend with respect to the rear bodies 3 and 17 about the rotation center.

The front frame 5 and the rear frame 6 are connected by a frame connecting elastic body 7. The front frame 5 and the rear frame 6 bend and extend in accordance with the movement of the front bodies 2 and 16 and the rear bodies 3 and 17 around the elastic body as a center of rotation.

FIG. 3 shows a connecting portion of the frame. When the frame connecting elastic body 21 does not exhibit a restoring force, or when it is desired to increase the restoring force, the front frame 19 and the rear frame 22 are connected by the reinforcing elastic body 20, and when the frame is bent, it is moved in the extension direction. The tension of the reinforced elastic body 20 works. The reinforced elastic body 20 is removable.
The user can be replaced according to the purpose.

Further, the frame can be fixed by the bending prevention stopper 24 so that the frame does not bend in a normal state so that the frame can be slid by conventional skating. Figure 4 shows this state.

FIG. 5 is a cross-sectional view of a wheel portion of the front wheel in which a one-way clutch 25 is provided. The axle 26 is firmly attached to the frame 28 so as not to rotate. A one-way clutch 25 having the same diameter is passed through the axle 26, so that the axle 26 rotates in the forward direction but does not function to reverse. The one-way clutch 25 can be replaced according to the purpose, and it is also possible to mount bearings that freely rotate in both directions.

FIG. 6 is a schematic diagram of a conventional skating method using skating. In order to prevent the wheel from rotating in the reverse direction and the baring force not being transmitted to the ground, the baring operation needs to be performed in a direction perpendicular to the wheel. Therefore, the toe of the baring foot is directed outward, and the baring direction is diagonally backward. As a result, the running direction becomes diagonally forward and its trajectory draws a zigzag to the target direction.

FIG. 7 is a schematic view of a straight run proposed by the present invention. The projection is in the same direction as the row of wheels, and the sliding direction is linear toward the target.

FIG. 8 shows the sliding operation of the linear sliding. The skating shoes are bent and the frame is bent when approaching the phase where the hind legs protrude. When propelled backward, the front wheels that are in contact with the ground generate a rotational force in the reverse rotation direction, but at least one of these wheels, including the first wheel, does not rotate due to the action of the anti-reverse mechanism and protrudes. The force acts on the ground and becomes propulsion.

Since this linear sliding motion has the same motion form as walking and running motion, it is characterized by less fatigue and easy acquisition of the motion as compared with the above-mentioned conventional sliding motion.

(Second Embodiment) In the first embodiment, the frame is cut off at the front side and the rear side and can be bent by using a connecting member. However, the frame is integrated and an elastic body is used at the bent portion. Is also good. Fig. 9 shows an example.

At least one of the front wheels 31 including the head is a one-way clutch.

The frame elastic body 30 in the intermediate portion between the front wheel 31 and the rear wheel 34 is a bendable elastic body, and when it bends, a restoring force acts in the extension direction.

When it is desired to increase the restoring force of the frame elastic body 30, a reinforced elastic body 33 can be mounted.

(Third Embodiment) In the first and second embodiments, the bent portion of the frame is the connecting portion 1 between the front wheel and the rear wheel.
It is provided at two places, but multiple bends may be used. FIG.
Figures 0 and 11 show examples where the frame is bent for each wheel.

FIG. 10 shows an embodiment in which the frame 30 is separated and connected by a frame connecting member 35, and FIG. 11 shows an embodiment in which the frame 39 is integrated and a frame elastic body 41 having a bent portion made of an elastic body is used.

(Fourth Embodiment) In the first embodiment, the shoe main body is divided into two parts so that the metatarsophalangeal joint can be bent.
You may be able to bend using a soft material like general sports shoes. An example is shown in FIG. Since the shoe body 42 is made of artificial leather or a similar material and is soft, it does not hinder the bending and extension of the frame.

(Fifth Embodiment) FIG. 13 shows an example in which a shoe 44 is fixed to a shoe body 43. When the skate shoes are not used, the shoes 44 can be separated from the shoe body 43 and used as ordinary shoes.

(Sixth Embodiment) In the first embodiment, the reverse running rotation is prevented by providing the one-way clutch. However, this is merely an example. May be used.

FIGS. 14 and 15 show an example in which a brake mechanism is provided to prevent reverse running rotation. When the front frames 47, 56 supporting the leading wheels bend, the brake cables 49, 54 are pulled, and the brakes 4 provided on at least one of the axles 52, 55 including the leading wheels.
5 and 53 work to prevent the wheel from turning.

(Seventh Embodiment) In the above-described embodiment, the elastic force is provided in the direction for urging the connection of a plurality of frames in the direction of extending, but the elastic force for maintaining the bent state is provided. It can also be

[0043]

[Effect of the Invention] Since it slides linearly with respect to the target, it is more efficient than conventional skating, and can run even if the width of the runway is narrow.

Since the sliding operation is similar to walking or running, it is easy to learn the technique, and since the developed muscle groups are mobilized, a large propulsion force can be obtained and further less fatigue.

Since the tension of the elastic body can be used when kicking out, a larger propulsive force can be obtained.
