Abstract
The disclosure relates to a brake system for a baby or child vehicle, and more particularly, to a brake system for a baby or child vehicle, in which the movement of the vehicle is controlled by locking a brake while an occupant is getting off the vehicle, and automatically releasing the brake in only a case where it is checked that the occupant is getting on the vehicle, thereby preventing a falling accident caused by the movement of the vehicle when the occupant gets on or off the vehicle or while a toddler stands up on the vehicle.
Claims5
A brake system for a baby or child vehicle, comprising
- a brake formed in a wheel;
- a brake line connected between the brake and a brake operation controller;
- and
- the brake operation controller connected to the brake line and configured to control tension of the brake line to lock and release the brake,
- wherein the brake is ordinarily locked and the brake operation controller interworking with a pair of safety bars operate the brake so that the brake is switched over from a locked state to a released state when an occupant gets on the baby or child vehicle and fastens the pair of safety bars, and
- wherein the pair of safety bars respectively comprise coupling units to couple with each other when positioned at a rear side of the baby or child vehicle, the coupling units being internally provided with magnets arranged to have opposite poles and coupled and held by the magnets accommodated therein when the pair of safety bar are rotated toward the rear side of the baby or child vehicle and unfastened.
