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 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 shopping trolley (10) comprising a basket (12) having first and second side walls (22, 23), first and second end walls (20, 21) and a base wall (18). The basket 12 includes first and second front legs (26, 27) and first and second rear legs (28, 29). The first and second front legs (26, 27) are rotatable from an extended position, in which they extend downwardly from adjacent a front of the basket 12, to a collapsed position, in which they are located adjacent outer sides of the first and second side walls (22, 23). The rear legs (28, 29) are rotatable from an extended position, in which they extend downwardly from adjacent a rear of the basket, to a collapsed position, in they are located adjacent and above upper edges of the first and second side walls (22, 23) of the basket (12).

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 foldable baby carriage frame which includes a handle assembly, a front leg assembly, a front leg support assembly, a rear leg assembly, a rear leg connecting assembly, a horizontal support rod and a torsion spring. The torsion spring is provided at the connection between the front leg support assembly and the rear leg connecting assembly, and the torsion spring controls the opening and closing of the front leg support assembly and the rear leg connecting assembly by the rotation. When downward force is applied to the rear leg assembly, the rear leg assembly pivots downward with the torsion spring as the pivot point, so that the front leg support assembly and the rear leg connecting assembly realizes the effect of automatic folding. After the downward force is released, the front leg support assembly and the rear leg connecting assembly return to the state when the baby carriage is in use.

Foldable stroller, foldable bassinet, foldable seat, stroller luggage and stroller wheel arrangement The present application discloses a foldable stroller, foldable bassinet, foldable seat, stroller luggage and stroller wheel design.

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 stroller includes a front leg, a rear leg, a handle assembly, a locking component and a linking component. The rear leg is rotatably connected to the front leg. The handle assembly is rotatably connected to the front leg. The locking component is movably disposed on the handle assembly. The locking component is configured to engage with the front leg for restraining a rotating movement of the handle assembly relative to the front leg and further to be driven to disengage from the front leg for allowing the rotating movement of the handle assembly relative to the front leg. The linking component is rotatably connected to the handle assembly and the rear leg. The handle assembly drives the rear leg to rotate relative to the front leg forwardly when the handle assembly rotates relative to the front leg forwardly. Therefore, the stroller can be folded easily and compactly.
