A foldable stroller frame includes a connection unit interconnecting two opposite foldable side frame units, each of which includes a front leg and a handle rod connected pivotally to each other, and a rear leg connected pivotally to the handle rod. The connection unit includes four bottom rods each having a first end connected pivotally to a connecting seat, and a second end connected pivotally to a respective one of the front and rear legs of the side frame units. When the connecting seat is pulled upwardly from a lower used position, the second ends of the bottom rods move radially toward each other, whereby the side frame units are folded and move toward each other.

A child push chair frame, such as a child push chair sports frame, buggy frame or similar vehicle frame for children, includes two rear wheels, at least one front wheel, and a pusher for pushing the child push chair frame. The child push chair frame may also include stabilizing struts that are foldable from a spread-apart travelling position into a fully folded-together transportation position and vice versa, and are latchable between these two positions and at least one further position, such as a parking position.

The invention is directed to a baby carriage, comprising lateral articulated joints, each 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 are pivotable relative to one another about an articulated axis extending transversely with respect to the travel direction, the connection for a first of at least two elements of an articulated joint which are pivotable relative to one another being connected in a rotatably fixed manner to an inner disk-shaped part of the articulated joint, and the connection for a second of the at least two elements of the articulated joint in question which are pivotable relative to one another being connected or coupled in a rotatably fixed manner to at least two housing end-face plates in parallel to the disk-shaped part, and/or to articulated plates of the articulated joint in question situated in between, the plates gripping the inner disk-shaped part at its two flat sides, wherein at least two housing end-face plates and/or articulated plates on both sides of the inner disk-shaped part may be pulled toward one another by means of a connecting part and thus frictionally and/or interlockingly pressed from both sides against the inner disk-shaped part of the articulated joint in order to lock the articulated joint, but by loosening the connecting part are releasable from the inner disk-shaped part to such an extent that the frictional and interlocking connection is released for relative adjustment of the articulated joint.

A carriage having a frame, where the frame is foldable between a use position and a storage position. The frame includes an attachment point for a plurality of frame components and a pivot lock for retaining the frame in the use position. The pivot lock is operated by rotating a portion of the frame of the carriage to unlock the pivot lock, permitting the carriage to be folded to the storage position.

A carrier device and a stowing method are disclosed. The rear wheel frame is disposed on the front wheel frame. The front wheel is disposed on a first end of the front wheel frame. The rear wheels are disposed on two ends of the rear wheel frame. The upper frame is disposed on a second end of the front wheel frame. The upper stoppers are disposed on the handle frame linkage, the upper frame or the handle frame. The carrier device has a stowing state including a stowing position, in the stowing position, a plane formed by the front wheel and a plane formed by one of the rear wheels are substantially perpendicular to each other, and the upper stoppers are disposed on two sides of the plane formed by the front wheel respectively. This disclosure has the advantages of easy folding and stowing.

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 baby stroller includes a frame having front and rear wheel supports, a seat rod, a push rod and a support rod. The front and rear wheel supports form a first rotating joint. The push rod includes upper and lower push rods, the lower push rod is connected to the first rotating joint. The lower push rod and the upper push rod form a second rotating joint. The support rod is rotatably connected with the upper push rod. The support rod is rotatably connected with the rear wheel support. The seat rod is rotatably connected with the front wheel support. The seat rod is rotatably connected with the support rod. Rotating the upper push rod around the second rotating joint drives the lower push rod, the support rod, the front wheel support, the rear wheel support and the seat rod to fold the stroller.

A carrier adjusting mechanism is applied to a stroller including a stroller frame and a carrier and includes a base, a locking structure, a locking device, and a release actuator. The base is connected to the stroller frame. The locking structure is connected to the carrier and pivoted to the base. The locking device is disposed between the base and the locking structure. The locking device includes a first engaging structure, a second engaging structure, and a locking member. The locking member is engaged with the first engaging structure at a first position or the second engaging structure at the second position. The release actuator is disposed on the stroller and connected to the locking device for disengaging the locking member from the first engaging structure or the second engaging structure, to allow the locking structure to move between the first position and the second position together with the carrier.
