A stroller includes a rear leg, a restraining member, a front leg, a wheel base and a wheel. The restraining member is disposed on the rear leg. The front leg is capable of being folded with respect to the rear leg. The wheel base is pivotally connected to the front leg. The wheel is pivotally connected to the wheel base. When the front leg is folded with respect to the rear leg, the restraining member restrains the wheel from rotating, so as to prevent the wheel from deflection. Accordingly, the folded stroller can stand stably and will not topple.

A storage assembly is installed on a frame of a child carrier. The storage assembly includes a storage component, a fixing base and a connecting component rotatably connected to the fixing base. One of the fixing base and the connecting component is fixedly connected to a handle of the frame, and the other of the fixing base and the connecting component is fixedly to the storage component. The storage component can be assembled on or disassembled from the handle through the fixing base and the connecting component. The storage component can rotate relative to the frame by relative rotation between the connecting component and the fixing base, so as to avoid interference with folding operation of the frame due to the storage component when folding the frame, and further facilitate folding operation of the child carrier, so that the child carrier can be folded to ideal volume for easy carrying.

A seat height adjustment mechanism includes a locking bar and a locking element. The locking bar is disposed in a stroller frame and has locking holes spaced apart. Each of the locking holes has a stop portion protruding therein. The locking element is mounted on a seat and has an engaging end. The engaging end is separably engaged in any one of the locking holes and has an engaging hook protruding in a direction, and the direction is crossed with another direction in which the engaging end moves when the engaging end is separating from the locking hole. The engaging hook separably presses against the stop portion. Therefore, the engaging end cannot separate from the locking hole. Even when wrongly operated, the locking element cannot be rotated and unlocked and thereby prevents the seat from unnecessarily sliding downward, so as to ensure safety of a baby at the seat.

A child stroller includes a stroller frame and a first seat. The stroller frame has two sections capable of being folded and unfolded relative to each other. The first seat is disposed on one of the two sections in a detachable manner. The first seat includes a supporting unit and a first seat frame. The first seat frame is adapted to hold the supporting unit. The first seat frame includes a seat hub, an upper seat tube and a lower seat tube. The seat hub is disposed on the stroller frame. The upper seat tube is disposed on the seat hub, and the supporting unit is slidably disposed on the upper seat tube. The lower seat tube is disposed on the seat hub and detachably connected to the supporting unit.

The tracked stroller frame device may allow a user to take a stroller with them when camping, hiking, or otherwise travelling over rough terrain. The device implements a continuous track system for providing additional tractive area and reducing or eliminating getting stuck on uneven surfaces, and may include a motorized mechanism for providing driving force. The tracked stroller device allows a user to take a baby or young child with them without carrying the baby or young child. The device may be collapsible for ease of storage and transporting and may incorporate a storage area to allow for transporting of other items. A braking system may also be implemented to slow down the device or keep it parked.

Disclosed are a rotational joint and a product for children having the rotational joint. The rotational joint comprises a first connecting base (1), a second connecting base (2) and a base (3) rotationally connected about a same rotation center line, the rotational joint further comprises a linkage member (4), and the linkage member (4) is arranged in such a manner that the linkage member is capable of only linearly moving relative to the base (3); one of the linkage member (4) and the first connecting base (1) is provided with a first guide slot (41), and the other one is provided with a first guide pillar (11), and the first guide pillar (11) is capable of being relatively slidably inserted in the first guide slot (41); one of the linkage member (4) and the second connecting base (2) is provided with a second guide slot (42), and the other one is provided with a second guide pillar (21), and the second guide pillar (21) is capable of being relatively slidably inserted in the second guide slot (42). When one rod member is driven to rotate, the other rod members can be linked to rotate relatively. The rotational joint can be used for products for children, such as strollers and child sitting saddles, to realize linked unfolding and folding of the respective rod members.

A pivotal joint structure is connected to a front leg and a bottom pipe of a stroller. The pivotal joint structure includes a connecting component disposed in the bottom pipe. A first end of the connecting component is fixedly connected to the front leg. The pivotal joint structure further includes an inner fixing component and an outer fixing component, which are disposed in the bottom pipe and connected to the bottom pipe. The connecting component is disposed between the inner fixing component and the outer fixing component, and the inner fixing component and the outer fixing component are rotatable around the connecting component. The front leg can be further folded relative to the bottom pipe by the pivotal joint structure. Therefore, the occupied space of the folded stroller can be further reduced, so as to facilitate carrying and storage when not in use.

A swivel seat stroller apparatus for providing varied seating for a child includes a frame including a plurality of wheel arms, a frame back, and a frame front. A plurality of wheels is coupled to the plurality of wheel arms. A seat back is coupled to the frame back. A seat bottom is coupled to the frame and has a seat aperture extending therethrough. A swivel seat has a rim coupled to the seat bottom and a harness rotatably coupled to the rim. A pad back is coupled to the seat back. A pad bottom is coupled to the pad back and moves between an open position covering the seat bottom and a closed position parallel with the pad back. A plurality of engagement members is coupled to the pad back and the pad bottom to selectively secure the pad bottom in the closed position.

A baby stroller for transporting an infant at speeds faster than normal walking is disclosed. This baby stroller can be folded to make it easier to stow and transport. The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.

A child stroller frame includes a first and a second frame portion, a pivoting part and a linkage. The second frame portion has a front end and a rear end, the front end of the second frame portion being pivotally connected with the first frame portion. The pivoting part has one end fixedly connected with a rear wheel support member and another end pivotally connected with the rear end of the second frame portion. The linkage movably couples the first frame portion to the pivoting part, and has an intermediate portion pivotally connected with the second frame portion, whereby the first frame portion and the rear wheel support member are movably linked for folding in a concurrent manner toward the second frame portion.
