Abstract

The present invention relates to a braking device for a quick board riding while pushing on one foot as a children's play equipment.

Existing quick boards use the aluminum plate cover used as the fender of the rear wheel as a braking device, and there is a danger of sudden stop due to lack of friction with the wheels.

In order to solve this problem, the urethane resin is equipped with a brake rubber that increases the friction force to enable quick braking of the quick board. By using the eccentric crank, the brake rubber is pressed onto the wheels to effectively apply braking. , Or by attaching a brake rubber to the inside of the existing mudguard aluminum to improve the frictional force to prevent the risk of accidents, characterized in that children can enjoy the quick board safely.

Description

Braking Device for Quick Boards {The Braking Device for Quick Board}

The present invention relates to a braking device for a quick board riding while pushing on one foot as a children's play equipment.

Recently, Quick Board, which is very popular worldwide, is finally booming in Korea. However, even if there is no braking device, even if the aluminum cover used as a fender on the wheel is pressed against the wheels and braked, the braking device using such metal aluminum causes friction by applying pressure to the wheel made of urethane, so that the friction is weak and easily. When you slip and go down a slope more than 15 °, you can't stop suddenly, which leads to an urgent situation. At this time, the children are embarrassed.

As the occurrence of accidents due to the failure of the braking device for the quick board is frequently reported through the mescom, the conventional quick board has a problem that the risk of an accident is always lost because the braking device cannot be in the control room.

The present invention aims to solve this problem, and the purpose of the quick board can be stopped suddenly to prevent children from accidents on the slopes.

To achieve this purpose, brake rubber is mounted on the rear wheel made of urethane resin and the brake rubber is pressed on the rear wheel by using an eccentric crank to enable quick braking of the quick board, or the brake rubber inside the aluminum fender cover. It is characterized by making it possible to apply rapid braking.

Referring to the present invention in detail by the drawings as follows.

Braking device that allows the rear wheel (1) of the quick board to be crimped with rubber. When the braking pressure is transmitted, the brake wheel (2) with excellent friction force and the rubber support (3) can be braked by the rear wheel immediately. Crankcase while connecting the crankcase (4) and the eccentric shaft rotational movement, which is connected to the rubber support and surrounds the crank (5) and smoothly transmits the pressure received according to the crank movement to the rubber support (3). An eccentric crank 5 for applying pressure to the crankcase 4 to push the rubber support 3 and a crankshaft 6 for transmitting rotational force to the crank and a crankshaft for fixing the crankshaft to the vehicle body 7. After the bracket (8) and the braking pressure, the spring (9) and the lever (10) for rotating the crankshaft (6) by the force of the lever and the spring (9) to return the foot plate (11) and the crankshaft (6) to their original positions are rotated. city Consists of a foot stool (11) applies pressure to tread group.

Referring to the operation of the present invention.

When the quickboard occupant is running down the slope and stops, when the brake foot 11 is pressed down, the pressure rotates the crankshaft 6 with a greater force by the lever 10 by the lever 10, and the crankshaft 6 When rotating, the eccentric crank 5 rotates left and right and up and down to reciprocate to transmit a force to the crankcase 4, and the crankcase 4 is connected to the rubber support 3 so that the rubber support 3 is connected to the rear wheel ( 1) When pushed toward the side, as shown in FIG. 5A, the brake rubber (2) coupled to the rubber support (3) elastically wraps the rear wheel (1) of the quick board made of urethane and compresses, causing perfect friction to rotate the rear wheel (1). Stopped.

In addition, in order to use the fender aluminum plate cover (12) installed on the rear wheel (1) of the conventional quick board as a braking device to rotate a certain angle without fixing one side of the aluminum plate, as shown in Figure 5B A) and attach the brake rubber (2 ') having a large friction force to the fender aluminum plate cover (12) by pressing down on the fender aluminum plate cover (12) to apply pressure to the fender aluminum plate cover (12). After the brake rubber 2 'compresses the rear wheel 1 to stop the rotation, the brake rubber 2' always returns to its original position to serve as a brake and a fender.

Conventionally, by simply pressing the aluminum plate for the fender, the friction with the rear wheel is weak and slipping and sudden stop are not possible. However, in the present invention, the elastic rubber and the large friction rubber brake the rear wheel of the quick board effectively by the lever and the crank. It is possible to prevent the danger by stopping suddenly, so that children can enjoy the quick board safely, and the brake rubber can be attached inside the fender aluminum plate cover used as a conventional quick board braking device to increase the braking effect.

Claims (2)
