Disclosed are a foldable joint having an unfolded position and a folded position, and a stroller having the foldable joint. The foldable joint comprises a base rod (1), a first rotary rod (2) and a second rotary rod (3), wherein one end portion of the base rod (1), one end portion of the first rotary rod (2) and one end portion of the second rotary rod (3) are rotationally connected to one another, a slider (4) is slidably arranged on the base rod (1), a driving part (41) is connected to the slider (4), a first guide portion (21) is arranged on the first rotary rod (2), a second guide portion (31) is arranged on the second rotary rod (3), and the driving part (41) is slidably fitted with the first guide portion (21) and the second guide portion (31) respectively. In the process of unfolding or folding the foldable joint, the driving part (41) moves relative to the first guide portion (21) and the second guide portion (31) simultaneously, and the driving part (41) moves along with the slider (4) relative to the base rod (1) such that the three components, i.e. the first rotary rod (2), the second rotary rod (3) and the base rod (1) are rotated relative to one another.

A foldable stroller frame and a foldable stroller are provided. The foldable stroller frame may include, a front wheel bracket, and a rear wheel bracket rotatably connected to the front wheel bracket. An upper end of the rear wheel bracket is rotatably connected to a side handrail, and a rear end thereof is rotatably connected to a rear supporting bar. The side handrail and the rear supporting bar are rotatably connected to a push bar from different shafts. The rear wheel bracket is provided with a slidable sleeve to which a front wheel bracket link and a side handrail link are rotatably connected, respectively. An end of the front wheel bracket link that is not connected to the slidable sleeve is rotatably connected to the front wheel bracket, and an end of the side handrail link that is not connected to the slidable sleeve is rotatably connected to the side handrail.

Provided herein is a baby stroller, which has an expanded mode and a folded mode, and includes a lower arm set, a connection part, a front wheel frame, a slide block, a rear wheel set, an upper frame, a first link rod set, a handling tube, a supporting rod set, two seat supports, and two second link rods. Due to the couplings between the slide block, the handling tube and the upper frame and the coupling between the slide block and the rear wheel rocker arms, the baby stroller may easily be folded so that it occupies considerably less space, and thereby improve its portability and facilitate its stowage and transportation.

A rugged suitcase and child carrier combination. The shell comprises a top half and bottom half each defining a hollow cavity. A foldable seat assembly is suspended in an opening defined by open halves of the shell, and various paraphernalia such as toys, bottles, entertainment devices, blankets, clothing, and food stuffs, among others, may be stowed in the hollow cavity defined by either of the top and bottom halves of the hinged shell. A plurality of wheels may be disposed on the bottom half of the device, and a telescoping handle may be disposed on an upper end of the top half of the shell to enable steering the device. The entire combination may be securably collapsed so that the seat assembly, as well as any stowed paraphernalia, is fully and securely encapsulated within the shell which may optionally be conveyed as a rolling suitcase.

A child transport carrier includes an upper frame member having a forward end and a rear end and a rear frame coupled to the upper frame member. The rear frame includes a lower rear frame member, an upper rear frame member having an upper end fixedly coupled to the rear end of the upper frame member, and a first joint assembly coupling the lower rear frame member and the upper rear frame member. The rear frame is configured to fold between an unfolded in-use position and a folded storage position. The upper frame member and the upper rear frame member are fixed relative to each other. The first joint assembly is disposed longitudinally rearward of the forward end of the upper frame member and longitudinally forward of the rear end of the upper frame member in the unfolded in-use position.
