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.

A child stroller apparatus includes a rear and a front leg frame respectively having a first and a second side segment, a handle frame having a grip portion and a third side segment respectively connected fixedly with a first and a second joining part that are pivotally connected with each other, a latching mechanism for locking the rear and front leg frames and the handle frame in an unfolded state, and a latch carried with the third side segment. The latch can engage and disengage the first joining part to lock and unlock the grip portion relative to the third side segment. Moreover, a linking part couples the latch to the rear leg frame or the front leg frame so that a folding rotation of the handle frame relative to the rear leg frame causes the latch to disengage from the first joining part.

A child seat is detachably mounted on a foldable stroller comprising a stroller handle and front and rear leg portions. The stroller handle is foldably connected to the rear leg portion. The front leg portion is foldably connected to the rear leg portion and has a first adaptor. The child seat includes a first pivot and a seat frame having a lower seat portion and an upper seat portion foldably connected to the lower seat portion. The first pivot is pivotably connected to the lower seat portion and detachably mounted on the first adaptor. When the front leg portion and the stroller handle are folded relative to the rear leg portion, the upper seat portion is folded on the lower seat portion, and the lower seat portion is folded on the front leg portion via the first pivot together with the upper seat portion.

Proposed is a baby carriage having improved convenience of use, the baby carriage including a main frame, a seat frame, a storage basket, and a wheel unit, wherein the baby carriage is generally used as a single baby carriage and a seat is detachably coupled to the rear of the single baby carriage such that the single baby carriage is utilized as a twin baby carriage when a second baby is born, and wherein it is possible to carry a pet in the baby carriage irrespective of carrying a baby or an infant in the baby carriage, whereby the baby carriage is used in various forms depending on circumstances of a user or a home.

A baby carriage having lateral articulated joints, each lateral articulated joint having a connection for a leg of a push bar, a front wheel strut and/or a rear wheel strut, of which at least two elements of the baby carriage are pivotable relative to one another about an articulated axis extending transversely with respect to the travel direction of the baby carriage. The at least two elements of the baby carriage being connected at an articulated joint, so as to be pivotable relative to one another, coupled together in a rotatably fixed manner so as to not be pivotable to one another. The lateral articulated joints being configured to be selectively released and selectively fixed, whereby to permit selective pivoting of some elements of the baby carriage relative to other elements of the baby carriage.

Disclosed is a stroller chassis with a hub. The stroller chassis comprises a first frame assembly and a second frame assembly. The hub is configured to couple the first frame assembly to the second frame assembly pivotably about a pivot axis and releasably lockably with respect to each other. The hub is configured to detachably and lockably support a carrying structure on the chassis. The hub is configured to support the carrying structure relative to the chassis pivotably about the pivot axis and lockably in a rotational position. Also disclosed is a stroller chassis with a hub. The hub is configured to detachably and lockably support a carrying structure on the chassis. The hub is configured such that fully unlocking the carrying structure from said hub to allow detachment may be caused by operation of only one release member.

Disclosed is a cart of a telescopic structure, comprising: a telescopic rod; a telescopic tube, where at least one of the telescopic tube and the telescopic rod have a hollow structure acting as an accommodation space that is required when the telescopic tube and the telescopic rod collapse into each other; a linkage mechanism connected to one end of the telescopic tube that is away from the hollow structure, and connected to one end of the telescopic rod that is close to the hollow structure; and a frame connected to the linkage mechanism. When the frame is rotated with respect to the linkage mechanism and collapses, the telescopic tube is also rotated with respect to the linkage mechanism, and one of the telescopic tube and the telescopic rod is retracted into the other thereof by means of the linkage mechanism.

A stroller assembly may include a stroller frame, a plurality of wheels, and a support. The stroller frame may include a front horizontal bar and a rear horizontal bar. The stroller frame may be configured to operate between an open position and a collapsed position. The plurality of wheels may be connected to the stroller frame. The plurality of wheels may include one or more front wheels and one or more rear wheels. The support may be connected to the stroller frame. The support may include a first arm, a second arm, and a support wheel. The support and the one or more rear wheels may be configured to support the stroller assembly in a substantially vertical position when the stroller frame is in the collapsed position.

A vehicle frame applied to a baby stroller includes a first tube, a second tube, a third tube and a foldable unit. The second tube is pivoted to the first tube. The third tube is pivoted to the second tube. The foldable unit includes a fourth tube. An end of the fourth tube is pivoted to the first tube, and the other end of the fourth tube is pivoted to the third tube. A linkage mechanism is formed by the first tube, the second tube, the third tube and the fourth tube. Rotation of the first tube moves the second tube and the third tube close to each other or away from each other via the fourth tube for folding or unfolding the vehicle frame. The present invention can simultaneously fold all tubes of the vehicle frame, and have advantages the simple structure, easy operation and low production cost.

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.
