Description

Braking Wheel

The present invention relates to a wheel mounted on a board or the like, and in particular, the braking is released when the boarding is configured so that the braking is applied when getting off.

The bottom of the board is equipped with wheels to travel by the movement of the occupants. The wheels mounted on the board are rotated by the movement of the occupant. Even when the passenger gets off the board, the board continues to rotate by inertia.

That is, even if the occupant gets off the board, as the board continues to run by inertia, the board moves away from the point where the occupant gets off, and thus, the board has to be moved away to have a board that is stopped far from the getting off point. .

In addition, since the board is moved by inertia in the state where the occupant gets off, there is a problem in that it can not be controlled and bumps into a pedestrian or hits a vehicle or a building, causing injury to others or breaking the board.

The present invention has been invented to solve the problems of the prior art as described above, when the occupant gets off the board, the brake is applied by the elastic force, the board does not move far away by inertia, the passenger can stop at the point of getting off The purpose is to provide a braking wheel that has been configured.

The braking wheel of the present invention for achieving the above object is a yoke for supporting the mounted wheel to rotate freely, the cast plate is fixed to the wheel and the brake pad is mounted on the moving body, and by a load applied from the top A hinge shaft hinged to the cast plate and the yoke so that the yoke pivots up and down; and the yoke rotates when the load is applied so that the wheel and the brake pad are spaced apart, and the yoke rotates when the load is released. And an elastic body connecting the yoke and the cast plate so that the brake pad provides an elastic force for pressing the wheel.

In addition, according to a preferred embodiment of the present invention, the yoke bolt is fixed to the yoke in an oblique direction, the fastening bolt is rotatably fixed to the movable body through the cast plate, the yoke is rotated relative to the fastening bolt do.

In addition, according to a preferred embodiment of the present invention, the elastic body is a torsion spring, the hinge shaft passes through the circular ring of the torsion spring, one end of the torsion spring is fixed to the yoke, the other end of the torsion spring It is fixed to the cast plate.

In addition, according to a preferred embodiment of the present invention, the movable body is a board, a fixing bracket is fixed to the bottom of the board and the cast plate is mounted on the fixing bracket.

In addition, according to a preferred embodiment of the present invention, the cast plate is mounted with a bearing so that the plate relative to the fixed bracket.

As described above, the brake wheel of the present invention, when the passenger gets off the board, the brake pad presses the wheel by the elasticity of the torsion spring to brake the board, so that the board does not move far away by inertia and stops at the point of getting off. By doing so, there is an advantage that the occupant does not have to move far to have the board as in the prior art.

In addition, the braking wheel of the present invention has the advantage that it is possible to solve the problem that the board hits the pedestrian and the problem that the board hits the vehicle or building as in the prior art stops at the stop point.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the brake wheel according to the present invention will be described in detail.

And Figure 4 is an exploded perspective view of the wheel shown in Figure 2, Figure 5 is a conceptual diagram showing a state when driving the wheel shown in Figure 3, Figure 6 is a conceptual diagram showing a state when braking the wheel shown in FIG. .

As shown in FIG. 1, a fixing bracket 3 is mounted on a bottom surface of the board 1, and a braking wheel 100 is mounted on the fixing bracket 3.

2 and 3, the brake wheel 100 is rotatably mounted to the yoke 103, the wheel 101, the fastening bolt 105 of the yoke 103 is cast plate 110 Through and fixed to the fixing bracket 3, the cast plate 110 is mounted with a bearing 111. Here, the fastening bolt 105 has a direction while rotating the yoke 103 relative to the fastening bolt 105 inclined diagonally as the fastening bolt 105 is fastened and fixed to the fixing bracket (3).

Hereinafter, the braking wheel configured as described above will be described in detail.

As shown in FIG. 3, the braking wheel 100 supports the wheel 101 and the yoke 103 coupled to the wheel 101 to rotate, and the fastening bolt 105 formed on the yoke 103 pass through. And a cast plate 110 hinged to the yoke 103, a brake pad 113 fixed to the cast plate 110 to correspond to the wheel 101, and the cast plate 110 hinged. Both ends are fixed to the yoke 103 and the torsion spring 117 through which the hinge shaft 115 penetrates the circular ring, and the cast plate 110 rotates while the cast plate 110 is mounted on the fixing bracket 3. It includes a bearing 111 mounted on the upper surface of the, the fastening bolt 105 is rotatably fixed to the fixing bracket (3) in the state passing through the cast plate (110).

Accordingly, the cast plate 110 rotates around the fastening bolt 105 by the bearing 111, and the yoke 103 hinged to the cast plate 110 is also fastened to the fastening bolt 105 based on the fastening bolt 105. Rotate around).

On the other hand, the cast plate 110 and the yoke 103 is hinged so that the yoke 103 can be pivoted up and down about the hinge axis 115.

As the yoke 103 pivots about the hinge shaft 115 in the vertical direction, the torsion spring 117 is elastically deformed in the direction in which both ends thereof are narrowed or opened by the yoke 103. The hinge shaft 115 penetrates through the circular ring of the torsion spring 117, one end of the torsion spring 117 is fixed to the yoke 103, and the other end of the torsion spring 117 is fixed to the cast plate 110.

Therefore, when the occupant boards the board 1, the force is applied downward in the vertical direction as shown in FIG. 5, and the wheels 101 are moved to the rear with respect to the hinge shaft 115 and the fixed bracket 3 is moved. And the cast plate 110 is lowered downward and the yoke 103 is inclined at a more inclined inclination, that is, a small inclination angle, so that the wheel 101 is moved to the rear.

At this time, the torsion spring 117 is forced in the direction in which both ends are opened, and the brake pad 113 fixed to the cast plate 110 is inclined with the yoke 103 lying further down so as to be spaced apart from the wheel 101. do.

In this way, when the occupant rides on the board 1 and a force is applied in the vertical downward direction, the yoke 103 lies down at a smaller inclination angle about the hinge axis 115, and as a result, the wheel 101 moves backwards. The brake pad 113 and the wheel 101 are separated so that the wheel 101 can freely rotate. In this state, the occupant rides on the board 1 while the braking is released.

On the other hand, when the occupant gets off the board (1), while the force applied to the vertical down at the time of boarding is released, both ends of the torsion spring 117 on the brake wheel 100 is generated in the resilient direction in the mutual folding.

The yoke 103 is pivoted in a direction erected around the hinge axis 115 by the elastic force while elastically restoring in the direction in which both ends of the torsion spring 117 are narrowed. That is, as the inclination of the yoke 103 increases, the wheel 101 pivots toward the brake pad 113 to come into contact with the brake pad 113. Therefore, the elastic force and the braking force of the torsion spring 117 are in proportion.

As such, the brake pad 113 presses the wheel 101 by the elastic force of the torsion spring 117 to apply braking, and the braking wheel 100 is automatically applied to the brake wheel 100 at the moment the passenger gets off the board 1. The rotation of the wheel 101 is stopped, so that the board 1 stops at the point where the occupant gets off.

Although the above-described braking wheel is described as an example of a direction caster having a directionality, it can be applied to general wheels other than the direction caster, and it is described that the brake wheel is mounted on a board, but not only the board but also various wheels Applies to moving objects For example, it can be applied to a chair equipped with a wheel.
