ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a braking device of a three wheel baby car, by which, the baby car may be braked steadily and easily.
2. Background of the Invention
In general, in order to brake a baby car so that it can stand still in the original place, a braking device is mounted on each wheel frame. If the baby car is necessarily to be braked, the user treads the braking devices on the two wheel frames. Another, if the baby car is required to be pushed, user needs to push upwards the braking device to release the baby cars. But this device is inconvenient, the user must brake two braking devices on the two rear wheels. If there is a device, by which the user only need one action to brake the two wheels simultaneously, then the user will feel convenient and easily.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to provide a braking device of a three wheel baby car, wherein a moving baby car is desired to be braked, the user only needs to move the protrusion of the braking device between the two rear wheel so as to drive the ejecting notches on the edge of long axis of a rotary portion within the braking device to engage with the inner ends of braking ejecting rods on the two sides. Thus, the original long axis contact with the inner end of the braking ejecting rod is changed as short axis contact. As a result, the braking rods on the two sides will be pushed outwards so that the two ends of the braking ejecting rod directly runs across the respect groove formed on the rear wheels. Accordingly, by this braking device, the baby car will be braked steadily.
The present invention will be better understood and its numerous objects and advantages will become apparent to those skilled in the art by referencing to the following drawings in which:
Another object of the present invention is to provide a braking device assembled at a three wheel baby car. Thereby, if the baby car is required to be braked, the user is only necessary to move a rotary portion, then the baby car will be braked easily.
