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.

A stroller, comprises two side supports (100) respectively disposed on the left and right sides, and the side support (100) on each side comprises a front support (1), a rear support (2), a push rod (3), an upper support rod (4), an upper connecting rod (5), a rear connecting rod (6), a lower connecting rod (7), and a sliding member (8) disposed on the rear support (2) and capable of sliding up and down along the length extension direction of the rear support (2), wherein the rear connecting rod (6) is pivotally connected to the upper support rod (4), one end portion of the rear connecting rod (6) is pivotally connected with the sliding member (8), the other end portion of the rear connecting rod (6) is pivotally connected with a lower portion of the upper connecting rod (5), an upper portion of the upper connecting rod (5) is pivotally connected to the push rod (3), one end portion of the lower connecting rod (7) is pivotally connected to the front support (1), and the other end portion of the lower connecting rod (7) is pivotally connected with the sliding member (8). When a stroller frame is folded, the sliding member (8) slides downwardly along the rear support (2), and the upper support rod (4) rotates backward and folds up on a rear side of the rear support (2). The stroller frame can be unfolded or folded by pressing or pulling the push rod (3) with one single hand, and the folded frame is flat and neat, and has a volume small enough for transportation and carrying.

Disclosed is a cart of a telescopic structure, comprising: a telescopic rod; a telescopic tube, where at least one of the telescopic tube and the telescopic rod have a hollow structure acting as an accommodation space that is required when the telescopic tube and the telescopic rod collapse into each other; a linkage mechanism connected to one end of the telescopic tube that is away from the hollow structure, and connected to one end of the telescopic rod that is close to the hollow structure; and a frame connected to the linkage mechanism. When the frame is rotated with respect to the linkage mechanism and collapses, the telescopic tube is also rotated with respect to the linkage mechanism, and one of the telescopic tube and the telescopic rod is retracted into the other thereof by means of the linkage mechanism.

A child stroller apparatus includes a standing frame, a push handle frame having a side segment, the side segment being pivotally connected with the standing frame via a pivot connection, an adapter having a coupling portion configured to receive the installation of a detachable part, the adapter being fixedly connected with a handle, the handle having a cavity through which is slidably disposed the side segment so that the handle and the adapter are slidable in unison along the side segment for adjustment, and a locking mechanism for locking the adapter in position on the side segment, the locking mechanism including a release actuator exposed on the handle for operation, the release actuator being operable to cause the locking mechanism to unlock for sliding adjustment of the handle and the adapter along the side segment.

Foldable strollers with removable seats and related methods are disclosed herein. An example stroller disclosed herein a wheeled frame, a receiver coupled to the frame, and a seat. The seat includes a mount, a lock disposed in the mount; and a handle having an extended positon and a retracted position relative to the seat. The lock is to move from a first position to a second position when the mount is disposed in the receiver to removably couple the seat to the frame, and the lock to move from the second position to the first position to release the seat from the receiver when the handle moves from the retracted position to the extended position.

A cross-over stroller kit is provided. The kit has a main frame assembly to receive at least one child seat assembly. The main frame assembly has a rear wheelbase and an upper attachment feature adapted to receive a lower attachment feature provided on first and second front-end frame assemblies. The first front-end frame assembly has two front wheels and the lower attachment feature adapted to mate with the upper attachment feature to define a city-mode stroller having four wheels. The second front-end frame assembly has a single front wheel and a second lower attachment feature adapted to mate with the upper attachment feature to define a sport-mode stroller having three wheels.
