摘要： A stroller which is foldable to a flat rectangular configuration has an occupant seating structure, seat supporting structure, seat supporting members extending downwardly from the seat to ground engaging wheels, and a handle connected to one of the structures for transmitting motive and steering forces. Bearing structure transmits load forces from the seat to the seat supporting members and rotatably supports each seat supporting member for pivotal folding movement so that the wheel supporting structure is foldable to an orientation generally parallel with and closely adjacent the occupant seat. The handle is pivotally foldable about an axis vertically adjacent the seat so that the folded handle is orientated substantially parallel with and closely adjacent the seat.

摘要： A carriage, chair, or similar structure is described having two cross frames which are interpivotally connected by means of a two axis pivot joint and which are held in their unfolded position at a fixed angle with respect to each other by rigid brace members pivotally connected to the sides of the frames and characterized in that the said brace members each comprise three sections, the middle sections provide horizontal rests for arms. The carriage, chair, or similar structure also incorporates a two piece toggle bar, and three piece knuckle strut disposed in front to serve both as a support member for the carriage structure and as a rest or support member for the object, e.g., a passenger, to be placed in the structure.

摘要： A folding structure in one embodiment including ground wheels and handles to form a child's stroller, the structure having a pair of elongated frame tubes that are laterally foldable and held together at two spaced points on each of the tubes by pivotally connected front and rear X braces, the structure also including a pair of elongated seat tubes pivotally attached to main frame tube-supported folding mechanisms that allow the seat tubes to move upwardly and in closer angular alignment with the main frame tubes when the latter move closer together as the structure is changed from its unfolded to folded configuration, resulting in a folded cross-sectional area not much greater than the sum of the cross-sectional areas of the individual members.

摘要： The stroller with a linkage-foldable backrest having a stroller frame convertible between an unfolded state and a folded state is provided. The folding of the stroller frame of the provided stroller drives the backrest portion to fold, so as to prevent the edge of the end portion of the backrest portion from touching the ground. The folding operation of the backrest portion according to the present invention is simple and convenient.

摘要： A baby stroller and a lateral seat cover portion thereof are provided. The lateral seat cover portion of a baby stroller includes a fabric bag including an inner side fabric and an outer side fabric opposite to each other, a foldable plate wrapped in the fabric bag and located between the inner side fabric and the outer side fabric, and an auxiliary device. The foldable plate includes a first plate and a second plate pivotally connected, when a frame of the baby stroller in an unfolded state, the foldable plate is in an unfolded state. When the frame of the baby stroller is folded, the auxiliary device enables an outer side of the first plate and an outer side of the second plate to approach each other, thereby switching the foldable plate from the unfolded state to a folded state.

摘要： A collapsible stroller includes a stroller frame, at least one hinge mechanism, and a hinge lock mechanism. The stroller frame is movable between a deployed position and a collapsed position. The at least one hinge mechanism is on the stroller frame and allows for movement of the stroller frame between the collapsed position and the deployed position. The hinge lock mechanism is capable of a locked state and an unlocked state. In the locked state, the hinge lock mechanism locks the at least one hinge mechanism to maintain the stroller frame in the deployed position. In the unlocked state, the hinge lock mechanism allows the stroller frame to move from the deployed position toward the collapsed position. The hinge lock mechanism includes a manually actuated first linkage and a manually actuated second linkage.

摘要： The present invention relates to a buggy or collapsible perambulator. It is comprised of a sliding frame which, in the unfolded state, runs in an inclined plane and has a division, in the region of which joints are located, and therefore, upon collapsing, an upper portion of the sliding frame is pivotable in relation to a lower portion of the sliding frame about the approximately horizontal axis of said joints. It is further comprised of an underframe with wheels, wherein, in the collapsed state, the lower portion and upper portion of the sliding frame and at least parts of the underframe are virtually parallel or are at a flat angle to each other and the buggy assumes a flat, compact state. The two sliding-frame portions which are pivotable in relation to each other each have approximately the shape of a U bar.
