Abstract
The utility model relates to a scooter, comprising a body 9; wherein, trolleys 8 are arranged beneath the body 9; the lower end of an operating rod 1 is hinged on the body 9; the upper end of the operating rod 1 is arranged in the front of the body 9; the lower end of the operating rod 1 is connected with a braking apparatus with a braking skin 7; the operating rod 1 has three operating positions, that is, a front braking position, a central sliding position and a back braking position. Compared with the prior art, the utility model is safe and reliable to completely prevent the accidents caused by braking by mistake.
Description
Technical field
The utility model relates to a kind of coaster with bidirectional brake device.
Background technology
Coaster is a kind of unpowered manned dolly with brake gear, can be that sloping type is layered on or frame on the ground chute or track on rely on gravity from slide.The visitor controls sliding and braking of coaster by the control stick that is positioned at coaster middle part or both sides.Existing coaster is seen accompanying drawing 1.
The coaster that the coaster that present domestic each slideway operator is using and domestic and international each slideway device fabrication producer are produced, the characteristics of its brake gear all be the visitor be sitting in pull back on the coaster control stick for the brake, pushing away control stick forward is releasing of brake, and promptly coaster is slided downwards along sloping type chute or track by the gravity effect of visitor and coaster itself.In sliding the way, visitor's both hands are held control stick all the time and are kept preceding push mode, and when as the front emergency taking place, the visitor pulls back control stick and brakes.For example the Chinese utility model patent specification of the CN2267078Y that announced on November 12nd, 1997 discloses the coaster with unidirectional like this brake gear.But when the visitor so that approximately per hour 40 kilometers speed slides, achievement in research according to the safety ergonomics, the visitor is easy to occur the brake operation error, promptly when wanting to brake, do not pull back control stick, continue to push away control stick forward but produce maloperation, the generation of accident can not be stopped and cause to its result.The coaster brake gear operating reliability of existing single direction is poor, has potential safety hazard.In the actual operation of slideway a lot of such accidents taking place really also, threatens for numerous visitors' personal safety.
The content of utility model
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of safe and reliable, the coaster that can avoid brake misoperation is provided.
Coaster of the present utility model comprises car body 9, control stick 1 and is installed in roller 8 below the car body 9, the lower end of control stick 1 is hinged on the car body 9, the upper end is positioned at the top of described car body 9, the lower end of described control stick 1 is connected with a cover brake gear and has brake rubber block 7, control stick 1 has three operating positions, be front brake position, middle sliding position and back normal danger, described control stick 1 so is connected with described brake gear, be control stick 1 at middle sliding position, described brake gear with brake rubber block 7 be in towards the collapsed state of car body 9; Control stick 1 is in forward and backward normal danger, described brake gear with brake rubber block 7 be in the state that stretches out away from car body 9.
Coaster of the present utility model in use, the visitor is sitting in and pulls back control stick on the coaster for brake, pushes away control stick forward in the centre position, coaster slides, and continues to push away control stick forward and can brake again.When in sliding, running into emergency and need brake, both can pull back control stick, can also push away control stick forward, thereby overcome the disadvantage that existing coaster brake gear is prone to maloperation, the possibility of having got rid of brake misoperation, improve the operating reliability of coaster, thoroughly eliminated potential safety hazard.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
