Abstract: According to the application, a handrail mechanism for a baby carriage includes: a shell having an accommodating space; a handrail connecting part having a free end and a pivotal end, the pivotal end being pivotally connected to the shell; and an elastic member arranged in the accommodating space of the shell, the elastic member having one end connected to the shell, and the other end connected to the handrail connecting part. Among them, the handrail connecting part is able to be pivoted between a bounced up position and a pressed down position, the free end of the handrail connecting part is away from the shell in the bounced up position and is close the shell in the pressed down position, the elastic member is arranged to bias the handrail connecting part toward the bounced up position, and when an external force is applied to overcome an action of the elastic member, the handrail connecting part is able to be pivoted from the bounced up position to the pressed down position.

Abstract: A stroller includes a rear leg, a restraining member, a front leg, a wheel base and a wheel. The restraining member is disposed on the rear leg. The front leg is capable of being folded with respect to the rear leg. The wheel base is pivotally connected to the front leg. The wheel is pivotally connected to the wheel base. When the front leg is folded with respect to the rear leg, the restraining member restrains the wheel from rotating, so as to prevent the wheel from deflection. Accordingly, the folded stroller can stand stably and will not topple.

Abstract: This disclosure provides a basket avoidance mechanism including a first tubing, a second tubing, a fixing member arranged on first tubing and a locking member arranged on the second tubing. The fixing member extends towards the locking member towards the locking member to form an abutting part, and the locking member extends corresponding to the abutting part to form an abutted part. When the first tubing is unfolded, the second tubing is in an unfolded position under a support of the first tubing by abutment of the abutting part against the abutted part; and when the first tubing is folded, the second tubing is folded to a folded position by avoiding abutment of the abutting part against the abutted part. The basket avoidance mechanism enables the basket tube to be unfolded or folded smoothly, and its structure is simple. A baby stroller frame is also provided.

Abstract: A foldable backrest returning mechanism including a backrest plate and an elastic returning device is disclosed. The backrest plate has a foldable portion. The foldable portion divides the backrest plate at least into a first plate and a second plate. The first plate and the second plate are foldable relative to the foldable portion. The elastic returning device is assembled between the first plate and the second plate, the elastic returning device provides an elastic force to drive the first plate and the second plate to approach each other relative to the foldable portion for making front surfaces of the first plate and the second plate have a returning tendency to approach toward each other. Accordingly, the present invention can prevent arching of the backrest plate at the foldable portion. Furthermore, the present invention provides an infant carrier.
