摘要： A foldable car seat carriage includes a frame unit and an engagement unit. The frame unit includes two leg frames. Each of the leg frames includes two legs pivotable relative to each other, and a driving mechanism. The driving mechanism has opposite ends connected pivotally to the legs at first and second intersections. The engagement unit includes two bayonets. Each of the bayonets has a linking portion connected pivotally to the driving mechanism of a respective one of the leg frames. For each of the leg frames, change of a distance between the first and second intersections of the driving mechanism and the legs during pivot action of the legs converts a position of the engagement unit relative to the legs.

摘要： A child stroller frame includes a first and a second frame portion, a pivoting part connected fixedly with a wheel support member and pivotally connected with the second frame portion, and a linkage. The first frame portion includes a handle frame segment, a front leg segment, and a coupling part that pivotally connects the handle frame segment with the front leg segment, and the second frame portion is pivotally connected with any of the handle frame segment, the front leg segment and the coupling part. The linkage has a first end pivotally connected with any of the handle frame segment, the front leg segment and the coupling part, a second end pivotally connected with the pivoting part, and an intermediate portion pivotally connected with the second frame portion, whereby the first frame portion and the wheel support member are movably linked for folding concurrently toward the second frame portion.

摘要： In one example, a child carriage has a frame with wheels. The frame has a coupler that removably couples the child carriage to a child carrier, such as a seat or bassinet. The frame has first and second leg assemblies, each having a front leg and a rear leg that are pivotably coupled about a first axis. The first crosspiece extends between the front legs of the first and second leg assemblies, and the second crosspiece extends between the rear legs of the first and second leg assemblies. The carriage is devoid of any push handle that extends above the child carrier. The frame folds about (i) the first axis from an expanded configuration to a first folded configuration so as to align hinges of the first and second crosspieces along a second axis, and (ii) the second axis from the first folded configuration to a second folded configuration.

摘要： A baby stroller is provided and includes a stroller frame and a child carrier. The stroller frame includes two supports, a first fixing component, a second fixing component and a locking component. The first fixing component and the second fixing component are fixed on one and the other one of the two supports, respectively, and pivotally connected to each other. The locking component is movably disposed on the first fixing component and configured to engage with the second fixing component for restraining a folding action of the stroller frame. The child carrier is disposed on the stroller frame and pivotable relative to the stroller frame. The child carrier is for providing a releasing force to the locking component for disengaging the locking component from the second fixing component to allow the folding action of the stroller frame during a pivotal movement of the child carrier relative to the stroller frame.

摘要： The disclosure provides a baby stroller frame switchable between a stretched position and a retracted position, comprising a retracting-stretching device, a front leg, a rear leg, a front carrying stand, and a rear carrying stand. The front leg is pivotally connected to the retracting-stretching device. The rear leg is pivotally connected to the retracting-stretching device. The rear leg and the front leg perform a stretching or retracting movement in respect to each other by assistance of the retracting-stretching device. The front carrying stand is pivotally connected to the retracting-stretching device. The rear carrying stand is pivotally connected to the retracting-stretching device. The rear carrying stand and front carrying stand perform a stretching or retracting movement in respect to each other by assistance of the retracting-stretching device.

摘要： A foldable child carrier includes a seat portion pivotally connected to a stroller frame and a back-resting portion in a folded configuration relative to the seat portion; a lock mechanism between the seat portion and the stroller frame to lock up the position of the seat portion relative to the stroller frame; a movable actuator member between the seat portion and the back-resting portion; the actuator member being unable to release the lock mechanism when the back-resting portion is in a reclined position; and the movement of the actuator member allowing the lock mechanism to release the seat portion and the stroller frame when the back-resting portion is in a folded position, so that the seat portion can rotate relative to the stroller frame. The foldable child carrier of the present disclosure has at least such features as novel structure, user-friendliness, safety and liability, and easy portability and storage.
