The pivot shaft 2 penetrates the tube receiver 11 and is inserted into the pivot hole 412 of the pivot base 41, and the fixing bolt 22 is screwed to the thread 21 of the pivot shaft 2, and the control end 31 and the fixing portion 32. Are locked to the caster base 4 and the brake plate 1, and the brake plate 1 is arranged so as to form a certain distance from the rear wheel, and the rear wheel is stopped when the brake plate 1 is pressed downward. Therefore, the wheels are stopped immediately after braking.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a roller-through brake.

[0002]

[Prior art]

 In the conventional roller through, casters are installed before and after the caster table, and pedals are installed at appropriate places on the caster table. The user puts one foot on the pedal and operates the roller through by stepping on the ground with the other foot. When the roller through has a moving inertial force, the foot separates from the ground and the operation is repeated again before the speed is reduced and stopped. Through the above operations, the purpose of sport and leisure by roller-through has been achieved.

[0003] However, the conventional roller-thru is designed so that it can only move forward in a substantially straight line, and cannot change direction like a bicycle, so it lacks interest and a vertical pipe is provided in front of the caster base to pivotally attach a handle. Roller-thru was devised to change the direction of the front wheels using the steering wheel. However, many of the roller-throughs described above have a handle brake structure that pulls the brake body with a wire and stops the casters of the roller-through as in a general bicycle.

[0004]

[Problems to be solved by the invention]

 However, due to the flexibility of the wire, the braking effect of the steering wheel brake is reduced, and there is a problem that the roller-thru cannot be stopped quickly and moves a certain distance. An object of the present invention is to provide a roller-through brake that stops wheels quickly after braking.

[0005]

The roller-through brake according to the first aspect of the present invention includes a brake plate, a pivot shaft, and a spring, is provided on a caster table, is mounted on a rear wheel, and is provided at a distal end. A perforation for pivotally attaching the rear wheel is provided, and a pivot base having two opposed pivot holes at a front end is provided. The brake plate has a tube receiver formed at one end, the pivot shaft has a thread formed at one end of the shaft tube, a fixing bolt is screwed and connected, and the spring has two control ends and a fixing portion. The pivot shaft extends through the spring and brake plate receivers and is inserted into opposing pivot holes provided in the pivot platform. The fixing bolt is threadedly connected to the thread of the pivot shaft, the control end and the fixed part of the spring are respectively engaged with the caster base and the brake plate, and the brake plate is formed so as to have a fixed distance from the rear wheel. The rear wheels are stopped when the brake plate is pressed downward. Therefore, the wheels can be stopped immediately after the braking.

[0006]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an embodiment of the present invention. A hole 411 for mounting the rear wheel 5 on the caster table 4 provided with a brake plate 1, a pivot shaft 2, and a spring 3 is provided at the end, and two holes are provided at the front end. A pivot mount 41 provided with opposing pivot holes 412 is provided.

[0007] The brake plate 1 is formed with a tube receiver 11 at an end and both sides of the brake plate 1 are formed in a U shape inclined outward. The pivot shaft 2 is provided with a thread 21 at one end of a shaft tube, and a fixed bolt 22 is screwed and connected. The spring 3 forms two control ends 31 and a U-shaped fixing part 32. The caster table 4 has a pivot mount 41 at the rear end, a rear wheel 5 is pivotally mounted on a perforation 411 at the end of the pivot table 41, and a pivot hole 412 is formed at the front end of the pivot mount 41, and the caster table 4 is A step board 6 is installed.

FIG. 2 and FIG. 3 show an embodiment of the present invention. The pivot shaft 2 penetrates the spring 3 and the brake plate 1 tube receiver 11, is inserted into the pivot hole 412 of the caster table 4 pivot mount 41, and the fixing bolt 22 is screwed into one end of the pivot shaft 2 shaft tube. It is screwed and connected to the mountain 21. The control end 31 and the fixed portion 32 of the spring 3 are locked to the caster base 4 and the brake plate 1, and the brake plate 1 is subjected to the action of the spring 3. Accordingly, the rear end of the tread plate 6 on the caster table 4 is pressed at a certain distance from the rear wheel 5 when the end of the brake plate 1 receives no force. FIG. 4 shows an embodiment of the present invention. When the brake plate 1 is directly pushed downward, the bottom surface of the brake plate 1 comes into direct contact with the rear wheel 5 and is stopped.

[0009]

[Effect of the invention]

 As described above, the roller-through brake of the present invention has a simple and practical brake structure in terms of implementation, and can surely quickly stop the wheels.
