The disclosure provides a baby carriage brake mechanism and a baby carriage. The baby carriage brake mechanism includes a frame, a brake drive assembly, linkage assemblies, brake locks and wheels. The brake drive assembly is disposed on the frame. The linkage assemblies are respectively slidably disposed on the frame on both of left and right sides. Both ends of the brake drive assembly are respectively in abutting connection with the two linkage assemblies. The linkage assemblies are coupled to the brake locks. Two wheels are respectively pivotally disposed at both sides of the frame. By driving the brake drive assembly to push the linkage assemblies to act with the brake locks, the brake locks on both sides are engaged with the wheels, thereby locking the wheels on both sides. Therefore, the baby carriage brake mechanism of the disclosure may brake wheels on both sides simultaneously with simple operation.

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.

Disclosed are a rotational joint and a product for children having the rotational joint. The rotational joint includes a first connecting base, a second connecting base and a base rotationally connected about a same rotation center line, the rotational joint further includes a linkage member, and the linkage member is arranged in such a manner that the linkage member is capable of only linearly moving relative to the base; the linkage member and the first connecting base is provided with a first guide slot and a first guide pillar the linkage member and the second connecting base is provided with a second guide slot and a second guide pillar 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 foldable baby stroller that can comprise collapsible telescoping support shafts connected by a hinged handle. Pivot assemblies support the support shafts and two pairs of legs including at least one pair of rotating legs and one pair of fixed legs, each leg including an attached wheel. The pair of rotating legs when in a closed configuration fit below, adjacent, and parallel to the fixed pair of legs with the attached respective wheels of each pair arranged in tandem. A hinged support brace links the pair of pivot assemblies and locks in an extended configuration. Two seat supports attaching a seat to the stroller and fold upward 90° to facilitate configuring between the extended configuration and folded configuration by folding upward. The pivot assemblies facilitate folding the support shafts when in the retracted configuration, and the two pairs of legs when in the retracted configuration, together into the folded configuration.

A stroller frame (100) includes a front leg (10), a bottom tube (30), a rear leg (20), an upper support member (40) and a lower support member (50). The front leg (10), the bottom tube (30), the lower support member (50) and the upper support member (40) are pivotally connected to each other to form a four-bar linkage structure. The rear leg (20) is connected to an end of the bottom tube (30). A lock mechanism (60) is disposed at a pivot joint between the upper support member (40) and the lower support member (50). The lock mechanism (60) is able to lock the upper support member (40) and the lower support member (50) at an expanded angle, such that the front leg (10) is able to be expanded with respect to the bottom tube (30). The lock mechanism (60) is unlocked to release the upper support member (40) and the lower support member (50), such that the front leg (10) is able to be folded with respect to the bottom tube (30).

A collapsible baby carriage includes a pair of middle pushing rod, a pair of upper pushing rod, a pair of T-rod, a pair of front wheel rod, a pair of bending-extension rod, a pair of side sliding rod, a pair of handle and a pair of seat side bending rod at two sides thereof. A top pushing rod, a seat bottom rod, a bottom connecting rod, a front wheel bottom rod and a rear wheel bottom rod are also between two sides of the baby carriage. The baby carriage includes a folding mechanism. The folding mechanism turns the upper pushing rod upward and the middle pushing rod and the front wheel rod downward. The flipping mechanism flips the seat side bending rods, the bending-extension rods, the front wheel rods, the front wheels, the handles, the T-rods and the rear wheels inward, forming a flat and rectangular body.

A collapsible stroller comprising a handle assembly, a front leg assembly and a rear leg assembly pivotably connected to one another such that the stroller is able to be moved between a folded configuration, where the front leg and handle assemblies are folded to positions substantially adjacent to the rear leg assembly, and an unfolded configuration, where the front leg and handle assemblies are unfolded to positions away from the rear leg assembly, and a link assembly comprising a front member and a rear member pivotally connected to one another, wherein the front member is pivotally connected to an intermediate portion of the front leg assembly and the rear member is pivotally connected to an intermediate portion of the rear leg assembly, such that when the stroller is moved to its folded configuration the front and rear members are folded toward each other to lie substantially adjacent to one another and the front and rear leg assemblies, and when the stroller is moved to its unfolded configuration the front and rear members are folded away from each other and the front and rear leg assemblies such that they are substantially coplanar with one another, and wherein the link assembly further comprises a biasing means for biasing the front and rear link members toward their unfolded positions.

A child carrier is provided and includes a frame, a seat and a folding device. The frame includes a handle, a first leg and a second leg. The first leg is pivotally connected to the handle. The second leg is pivoted to the handle. The folding device is installed between the frame and the seat. The folding device includes a sliding structure and a linking component. The sliding structure is fixedly disposed on the handle. The seat is slidably coupled to the sliding structure. The linking component includes a first end and a second end. The first end is pivotally coupled to the seat. The second end is pivotally connected to the second leg.

A foldable pushchair chassis, particularly a sport-model pushchair chassis, buggy chassis or similar vehicle chassis for children, comprising wheels and a push element for pushing the pushchair chassis, wherein said pushchair chassis can be brought at least into a lockable usage state and into a folded, lockable storage state, and a, particularly manual, actuation device is provided and configured such that during transfer from the locked usage state into the locked storage state, at least two locking procedures can occur, in particular both release of the locking in the usage state and adjustment of locking in the storage state, by means of a single first actuation of said actuation device.

The present disclosure provides a stroller capable of being folded twice, comprising: side support assemblies located at two sides and at least one transverse brace connected between the side support assemblies of the two sides, the side support assembly at each side comprises a push rod, a front wheel support and a rear wheel support which are rotatably connected to each other, and in a first folded state, the push rod, the front wheel support and the rear wheel support are rotated to be in a closed state; each transverse brace has a first transverse folding rotation point and a second transverse folding rotation point. The stroller is capable of achieving not only a first folding, but also a second folding of the two side support assemblies, so as to reduce the volume occupied by the entire stroller in these states.
