Description

Treadmill {Vehicle apparatus}

The present invention relates to a walking type vehicle device, and more particularly, to a walking type vehicle device in which an arc-shaped gear plate having the same centrifugal as the connecting pin is mounted inside the rear body and the turning part.

Conventional walking exercise equipment or walking vehicle apparatus moves forward while the user pushes back and pushes the ground with one foot. Although these walking machines are light and fast, they are supported only by the front and rear wheels. Therefore, there is a risk of losing the center of gravity and falling easily. And since most users habitually step on the ground with their right or left foot, they lose both balance in leg movement.

In addition, another conventional walking vehicle apparatus shown in FIG. 7 adjusts the direction by mounting one handle 35 at the front end of the turning unit 30, and on both rear sides of the turning unit 30. One rear body 31 is mounted on each of the two rear bodies 31, and one wheel support 32 is mounted on the rear of the two rear bodies 31, respectively. In addition, one rear wheel 33 is installed at the bottom of the wheel support 32, and one footrest 34 is installed at the appropriate position on the upper surface of the rear body so that the user can put his feet.

The walking vehicle device is moved forward by the biasing force generated from the two rear wheels 33 when the user unfolds both rear bodies 31 outward using the feet 36 and 36 '. Thus, foot and leg movement effects are obtained.

However, the conventional walking type vehicle apparatus as described above has a footrest 34 mounted directly on the rear body 31 when the rear body 31 is unfolded because the footrest 34 is directly coupled to the rear body 31. As the angle changes, the tip of the user's toe is inward, so the ankle may be damaged. In addition, to unfold the rear body 31, it is necessary to apply force to the foot, but it is not easy to apply force.

Thus, the present inventors have come to devise a walking vehicle device according to the present invention by reducing the fact that there is still a part to supplement in using the existing walking exercise device or walking vehicle device.

An object of the present invention is to provide a walking type vehicle device which further improves the balance performance in use.

Another object of the present invention is to provide a walking vehicle apparatus that can move forward effectively with less power.

Another object of the present invention is to provide a walking vehicle apparatus that can effectively avoid the foot damage of the user.

Hereinafter, a walking vehicle apparatus according to the present invention will be described in more detail with reference to the accompanying drawings.

First, as shown in FIGS. 1 and 2, the present invention relates to a walking vehicle apparatus, and includes one front wheel holder 1, one turning unit 13, two rear bodies 2, and two rear wheels ( 22).

Here, the direction change unit 13 is made of a hollow case shape and the front end of the direction change unit 13 is coupled to the front wheel support (1). One front wheel support (1) is equipped with one T-shaped handle (11) and one direction moving along the handle (11) at a position below the portion where the handle (11) and the front wheel support (1) are coupled to each other The adjusting front wheel 12 is installed. The rear body 2 is connected to both rear sides of the redirection unit 13, respectively. One side of each rear body 2 is mounted inside the turning unit 13 and connected to the turning unit 13 by one connecting pin 214 so that the rear body 2 can move on a plane. do.

Meanwhile, as shown in FIG. 2, one arc-shaped gear plate 212 centered on the connecting pin 214 is mounted inside each of the rear bodies 2 connected to the direction change unit 13 to provide two. Arc-shaped gear plate 212 is meshed with each other. In addition, the two footrests 24 on which the user's feet are placed are located at appropriate positions on the upper surface of the rear body 2, respectively. In addition, one spring fixing groove is symmetrically installed at an appropriate position inside the rear body 2 located between the two footrests 24 and the turning part 13. Each end of the spring 23 is inserted into the two spring fixing groove is fixed by the position fixing screw 232.

3 to 5, a first hole 201 and a second hole 202 are formed at appropriate positions of each rear body 2, and the first hole is formed on the bottom of the rear body 2; One arc slot 203 having the same shaft center as 201 is provided (see Fig. 5). The first hole 201 is formed for connection with the scaffold 24 (see FIGS. 3 and 4) and the second hole 202 is formed for engagement with the rear wheel 22 (FIG. 3). Reference). One bushing 26 is symmetrically installed on the top and bottom surfaces of the first hole 201, and the shape of each bushing 26 is the upper body 2 when the upper portion of the first hole 201 is covered. It has a projection 261 in contact with the upper surface of the upper surface of the first body 201 to be in contact with the lower surface of the rear body (2). In addition, one bottom shaft 241 is attached to the bottom of each footrest 24, and the middle shaft 241 penetrates the bushing 26, respectively. A bearing 27 is inserted between the intermediate shaft 241 and the bushing 26, and a flat plate 28 is installed in the bushing 26 positioned at the bottom of the first hole 201. A through hole is formed at an appropriate position of the flat plate 28 to fix the intermediate shaft 241 installed on the scaffold 24 by a fixing screw 29. One side of the flat plate 28 has a curved portion 281 which is bent upward, the curved portion 281 is inserted into the arc-shaped slot 203 of the secondary body (2). On one side of the other side of the plate 28, one connecting member 282 is rotatably mounted, respectively, and one end of each connecting member 282 has a bent portion 283 bent downward. The rear wheels 22 are also rotatably connected.

On the other hand, the shock absorbing portion 213 is mounted at an appropriate position on the inner side where the respective rear bodies 2 face each other, thereby absorbing the shock generated when the two rear bodies 2 come in contact with each other. (See Figure 2).

In addition, in the case of using the walking type vehicle apparatus of the present invention as shown in Figure 6, the user can adjust the direction using the handle. The two feet stand on the footrest 24 of the rear body 2, respectively, and push the rear body 2 at the same time by spreading outwardly by applying force to the two feet, the rear body 2 by the spring 23 in the next motion. Is closed inward. In the process of opening the rear body 2 to the outside and closing again, the driving force is generated by the rear wheel 22, so that the entire vehicle apparatus is moved forward. That is, in the present invention, the rear wheel 22 is formed by a kind of power to move the walking vehicle apparatus forward.

Here, due to the interlocking arc-shaped gear plate 212 provided in the rear body 2, when the rear body 2 is spread outwards, the same amount of force is simultaneously applied to the rear body 2 on both the left and right sides. Therefore, the angle at which the rear body 2 unfolds outward is the same. Therefore, a more balanced foot movement effect can be obtained.

In addition, since the two rear bodies 2 are connected to one spring 23 at an intermediate position, the rear bodies 2 are more easily closed by the elasticity of the springs when the user unfolds the rear bodies 2 outward and then closes them again. Therefore, it is easy to move the walking vehicle device with little force.

However, as shown in FIGS. 6 and 7, when the user uses the walking type vehicle apparatus of the present invention, the rear wheels rolled together in the direction in which the rear body is unfolded due to the repeated opening and closing of the rear body 2. The direction of 22 is changed by closing the rear body instantaneously, and a biasing force is generated in the rear wheel 22, so that the pedestrian vehicle apparatus moves relatively forward. In addition, according to the present invention, since the rear body 2 and the footrest 24 are coupled to rotate relative to each other by the middle axis (241 in FIG. 3), even when the user spreads the rear body 2 outward with both feet open, Since the scaffold 24 can rotate at the engaging portion of the rear body 2, the scaffold 24 can maintain a state that is always forward. Therefore, the user can prevent ankle damage that is commonly caused when a force is applied while the ankle is twisted conventionally.

In addition, since the footrest 24 is pinched by the arc-shaped slot 203 formed in the rear body 2 by the curved portion 281 formed in the flat plate 28 mounted on the bottom of the rear body 2, the rotation of the rear wheel 22 is performed. The angle can be limited, so that the footrest 24 can be prevented from rotating at an excessive angle, thereby ensuring the safety of the user and reducing the damage caused by the movement.

According to the present invention, unlike the conventional walking-type vehicle device, since the rear body 2 on both sides is opened at the same angle by the arc-shaped gear 212, it can give a uniform movement effect on both feet, the rear body (2) Since the footrest 24 is always in a straight line even in the state of being separated from each other, it is possible to reduce the problem that the user's ankle is twisted, and the footrest 24 by the arc slot 203 that regulates the rotation angle of the footrest 24. Rotation at an excessive angle can be prevented.
