Description
Technical field
The utility model relates to a kind of coaster with bidirectional safe brake gear.
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 central authorities 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, cause the generation of accident thereby can not stop.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.
