ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a stroller having a brake device which can be conveniently operated to stop rotation of two spaced-apart rear wheels thereof simultaneously so as to stop movement of the stroller.
2. Description of the Related Art
A conventional stroller is generally equipped with brake members mounted respectively on rear wheels thereof. The brake members are operated separately to stop rotation of the rear wheels, respectively. This may cause inconvenience during operation of the brake members. Moreover, this might result in overturning of the stroller when the stroller moves along a bumpy path or along a downward slope since the stroller cannot be stopped instantly.
A brake device that can be operated to simultaneously stop rotation of two rear wheels of a stroller has been suggested in the art. However, this type of brake device cannot be used with a stroller that is foldable by moving its lateral parts toward each other.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a stroller having a brake device which is operable to stop rotation of two spaced-apart rear wheels of the stroller simultaneously so as to stop movement of the stroller.
Accordingly, the stroller of the present invention includes apair of upright rear rods, a connecting frame, and a brake device. The rear rods are opposite to each other in a first direction. Each of the rear rods has a lower end provided with a rear wheel. The connecting frame extends between and interconnects the rear rods. The brake device includes a mounting seat, an operating member, an elongate linking member and a pair of braking members. The mounting seat is mounted on the connecting frame between the rear rods, and has a lower end portion provided with a retaining rod that extends in the first direction. The operating member has a slidable mounting portion which has a rear end disposed rearwardly of the mounting seat, and a front end extending from the rear end through the mounting seat. The slidable mounting portion is formed with an elongate slot which extends from the rear end to the front end of the slidable mounting portion in a second direction transverse to the first direction and which has the retaining rod extending therethrough such that the slidable mounting portion is movable in the second direction relative to the mounting seat. An operating portion extends rearwardly from the rear end of the slidable mounting portion. A downward extension extends downwardly from the slidable mounting portion. The linking member extends in the first direction, and has opposite first and second ends and an intermediate portion that is mounted on the downward extension of the operating member. Each of the brake members has an upper end connected to a respective one of the first and second ends of the linking member, a lower end, and an intermediate portion pivoted to a respective one of the rear rods about a pivot axis along the first direction. The brake members are pivotable about the pivot axis in a third direction for moving to a braking position, in which the lower ends of the brake members engage the rear wheels, respectively, to stop rotation of the rear wheels. The brake members are further pivotable about the pivot axis in a fourth direction opposite to the third direction for moving to a releasing position, in which the brake members are disengaged from the rear wheels to permit rotation of the rear wheels. The operating portion of the operating member is operable for turning rearward so as to cause the slidable mounting portion to slide rearwardly and to cause the downward extension and the linking member to move rearwardly relative to the mounting seat so as to enable the brake members to pivot about the pivot axis in the third direction for moving to the braking position. The operating portion of the operating member is further operable for turning forward so as to cause the slidable mounting portion to slide forwardly and to cause the downward extension and the linking member to move forwardly relative to the mounting seat so as to enable the brake members to pivot about the pivot axis in the fourth direction for moving to the releasing direction.
