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.

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.

The present disclosure relates to a double stroller, with a frame thereof including three side supports and two transverse supports. Each two adjacent side supports are connected to each other via one transverse support. Each transverse support includes at least one connecting rod assembly, and each connecting rod assembly includes an outer connecting rod fixedly connected with the side support on a left or right side and an inner connecting rod fixedly connected with the side support in the middle. The outer connecting rod is connected to the inner connecting rod in a horizontally rotatable manner. The outer connecting rods and inner connecting rods connected in a horizontally rotatable manner to enable the side supports on two sides to close together as the outer connecting, rods are turned transversely and folded, and thus, after being folded, the space occupied by the double stroller in the left-right direction is lessened.

A moving carrier is disclosed. A lower-frame assembly includes a first moving member disposed on the guiding member, a second moving member disposed on the guiding member, an elastic member disposed corresponding to the guiding member, and a third moving member disposed on the second moving member. A transmitting member of a front-wheel assembly has a guiding groove. One end of the third moving member is disposed in the guiding groove. When the first moving member moves along the guiding member, the first moving member enables the elastic member to store a first energy. When the elastic member releases the first energy, the second moving member drives the third moving member to move and the third moving member pushes the guiding groove to move, so that the transmitting member can drive the front-wheel frame to move toward the lower-frame assembly.

There is provided a leg folding mechanism, such as a leg folding mechanism for a push chair, the leg folding mechanism comprising a core member having a longitudinal axis and, preferably, first and second axially spaced core guides; a first leg member rotatably mounted on the core member, preferably at the first core guide; a second leg member rotatably mounted on the core member, preferably at the second core guide a shuttle disposed within the core member and moveable within the core member to cause movement of the legs as the shuttle moves within the core.

The invention relates to a children's vehicle having a vehicle body (10) on which are mounted a front wheel (31) and at least one rear wheel (32), a steering sub-assembly (20) having a steering column (21) linked to the front wheel (31) and a handlebar (22), a seat (41) configured to accommodate a child, a safety element (50) configured to surround at least a first area of the child's body when it is installed on the seat (41), the handlebar (22) being removable between: a first configuration in which the handlebar (22) is remote from the safety element (50), and a second configuration in which the handlebar (22) is close to the safety element (50) and surrounds a second area of the child's body.

A collapsible chassis for strollers includes a base frame supporting at least one front post and at least one rear post with wheel assemblies. The base frame further supports at least one handle tube. An actuation element is supported by the base frame and is actuated by the user to move the chassis from the open condition to the closed condition. The actuation element is movable with respect to both the handle tube and the movable post and is connected by way of a first kinematic connection element to the movable post and by way of a second kinematic connection element to the handle tube. Actuating the actuation element causes the rotation of the movable post and handle tube. A third kinematic connection element is provided which includes an articulation element adapted to cause a motion of mutual approach in a transverse direction of the two rear posts.

A compact multifunction collapsible stroller and cart which provides increased convenience with its small factor when collapsed. It is able to be reversibly converted from a stroller to a shopping or utility cart. The seat and receptacle of the invention have no rigid connections to the wheeled frame, instead they are suspended in place by non-rigid connections such as cables or wires connecting them to the wheeled frame. The wheeled frame may be telescopic and collapsible, and can be wrapped in the flexible material of the seat or cart receptacle thereby allowing the seat or cart receptacle to act as a carrying bag.

A moving carrier is disclosed. A lower-frame assembly includes a first moving member disposed on the guiding member, a second moving member disposed on the guiding member, an elastic member disposed corresponding to the guiding member, and a third moving member disposed on the second moving member. A transmitting member of a front-wheel assembly has a guiding groove. One end of the third moving member is disposed in the guiding groove. When the first moving member moves along the guiding member, the first moving member enables the elastic member to store a first energy. When the elastic member releases the first energy, the second moving member drives the third moving member to move and the third moving member pushes the guiding groove to move, so that the transmitting member can drive the front-wheel frame to move toward the lower-frame assembly.

The present disclosure relates to a double stroller, with a frame thereof including three side supports and two transverse supports. Each two adjacent side supports are connected to each other via one transverse support. Each transverse support includes at least one connecting rod assembly, and each connecting rod assembly includes an outer connecting rod fixedly connected with the side support on a left or right side and an inner connecting rod fixedly connected with the side support in the middle. The outer connecting rod is connected to the inner connecting rod in a horizontally rotatable manner. The outer connecting rods and inner connecting rods connected in a horizontally rotatable manner to enable the side supports on two sides to close together as the outer connecting, rods are turned transversely and folded, and thus, after being folded, the space occupied by the double stroller in the left-right direction is lessened.
