A support anti-breaking structure includes a first plate member (1), a second plate member (2) and a first fixing member (3). An end of the first plate member (1) is pivotally connected to an end of the second plate member (2) at a first pivotal connection (51). The first fixing member (3) is formed by a flexible structure and fixed to a side of the first pivotal connection (51). The first plate member (1) and the second plate member (2) can press the first fixing member (3), so that the first plate member (1) and the second plate member (2) can be rotatably folded. When the first plate member (1) rotates relative to the second plate member (2) in a direction of pulling the first fixing member (3), the first fixing member (3) will exert reaction force to the first plate member (1) and the second plate member (2) by structural strength itself, thereby restraining the rotation of the first plate member (1) relative to the second plate member (2), so as to effectively reduce the probability of breaking the first pivotal connection (51) due to incorrect operation of the rotation and folding.

Disclosed are a child seat frame and a compact foldable stroller. The child seat frame comprises a seat mounting part, a lower frame body, and an upper frame body, wherein the upper frame body is provided with an upper frame body lock which can be actuated to lock and disengage from a second latch part, and the upper frame body is pivotable relative to a lower seat frame hub when the upper frame body lock is disengaged from the lower seat frame hub; and when the lower frame body pivots relative to the seat mounting part, the upper frame body lock locks over the second latch part. The child seat frame can be folded in a main suitable for the folding boundary dimensions of a main stroller frame, thereby maintaining the folding dimensions of a stroller unit to a minimum.

The invention relates to a foldable device (3000) for transporting loads, the foldable device comprising: a first platform (3200); a running gear (3100), the running gear comprising a plurality of arms (3110) and a plurality of wheels (3130), each of the plurality of arms being rotatably coupled to the first platform and at least one of the plurality of wheels; and a device for aligning the plurality of arms and the plurality of wheels, which is configured to rotate each of the plurality of arms and each of the plurality of wheels by a rotary angle between at least one open and one folded state, wherein the plurality of arms and the plurality of wheels are arranged under the first platform when in the folded state.

A stroller includes a frame, a sliding member and a seat fixing base. The frame includes a front linkage rod and a transverse rod. The transverse rod is disposed with respect to the front linkage rod. The sliding member is rotatably connected between the transverse rod and the front linkage rod. The seat fixing base is rotatably connected to the transverse rod or the front linkage rod and slidably connected to the sliding member. When the frame is folded, the front linkage rod and the transverse rod move away from each other, such that the seat fixing base slides with respect to the sliding member.

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 child stroller apparatus includes a handle frame having a first side segment fixedly connected with a first coupling part, a front leg frame having a second side segment fixedly connected with a second coupling part, a rear leg frame having a third side segment fixedly connected with a shell, the third side segment being respectively connected pivotally with the first and second coupling parts, a linking member received at least partially inside the shell and respectively connected pivotally with the first and second coupling parts about two different pivot axes, the handle frame and the front leg frame being thereby rotationally linked to each other, and a latch disposed adjacent to the first coupling part, the latch being operable to rotationally lock the handle frame with respect to the rear leg frame so as to lock the infant stroller apparatus in an unfolded state.

A convertible car seat to stroller device includes a car seat that has a frame, which is rigid. A handle, which is extendable, is coupled to the frame. One of pair of cross supports, each comprising a front member and back member, is pivotally coupled to a bottom of the frame proximate to a left side of the frame. The other of the pair of cross supports is pivotally coupled to the bottom proximate to a right side of the frame. A front axle is rotationally couple to the front members. The front axle is coupled to a pair of front wheels. A back axle is rotationally coupled to the back members. The back axle is coupled to a pair of back wheels. The car seat is couplable to a base, which is couplable to the interior of a vehicle.

A stroller includes: a first stroller component and a second stroller component. At least one of the first and second stroller components is movable from a first position to a second position. The stroller also includes: a drive mechanism operatively engaged with the at least one of the first and second stroller components to move the at least one of the first and second stroller components from its first position to its second position; and a disengaging mechanism for disengaging the operative engagement between the drive mechanism and the at least one of the first and second stroller components to facilitate manual movement of the at least one of the first and second stroller components.

Foldable strollers and related methods are disclosed herein. An example frame for use with a stroller includes a first leg, a second leg, a first joint to couple the first leg and the second leg, a handle arm, and a second joint to couple the handle arm and the first leg. The second joint includes a first portion having a pocket and a second portion including a lock slidably disposed in the second portion. The lock is to be removably coupled to the pocket. The handle arm is to rotate relative to the first leg via the second joint when the lock is removed from the pocket. The rotation of the handle via the second joint is to enable the second leg to rotate relative to the first leg via the first joint to fold the frame.

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.
