An upper end of the rear wheel bracket is rotatably connected to a side handrail, and a rear end thereof is rotatably connected to a rear supporting bar. The side handrail and the rear supporting bar are rotatably connected to a push bar from different shafts. The rear wheel bracket is provided with a slidable sleeve to which a front wheel bracket link and a side handrail link are rotatably connected, respectively. An end of the front wheel bracket link that is not connected to the slidable sleeve is rotatably connected to the front wheel bracket, and an end of the side handrail link that is not connected to the slidable sleeve is rotatably connected to the side handrail.

Provided herein is a baby stroller, which has an expanded mode and a folded mode, and includes a lower arm set, a connection part, a front wheel frame, a slide block, a rear wheel set, an upper frame, a first link rod set, a handling tube, a supporting rod set, two seat supports, and two second link rods. Due to the couplings between the slide block, the handling tube and the upper frame and the coupling between the slide block and the rear wheel rocker arms, the baby stroller may easily be folded so that it occupies considerably less space, and thereby improve its portability and facilitate its stowage and transportation.

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.

A foldable stroller (1, 41) is provided with at least one pushrod (2, 3) being pivotable about a first pivot axis (9, 10). The folding mechanism is further provided with a number of rods, comprising a first rod (19, 20) being pivotable about a second pivot axis (17, 18). The first rod and the pushrod are provided with cooperating connecting elements (52, 56) being connectable to each other by pivoting the pushrod about the first pivot axis to an erect position of the pushrod, in which position the connecting elements are lockable to each other by locking means (57). When the locking means are unlocked and the connecting elements are still connected to each other, the connecting means prevent the first rod to pivot about the second pivot axis. After unlocking the locking means as well as after disconnecting the connecting elements by pivoting the pushrod about the first pivot axis towards a collapsed position of the pushrod, the first rod is pivotable about the second axis to achieve the collapsed position of the stroller.

A foldable stroller, movable between an unfolded state and a folded state, comprising: a central frame element (101) extending in a lateral direction of said stroller; a front wheel frame element (102) which is at one outer end pivotably connected to said central frame element (101) around a first axis, which first axis extends in said lateral direction, and comprising at least one front wheel (121) at its other outer end; a push bar connector frame element (103) which at one outer end is pivotably connected to said central frame element (101) around a second axis, which second axis extends in said lateral direction, and which at its other outer end comprises a push bar frame element (105) with a push bar (151); a first and second rear wheel frame element (104) each connected to said central frame element (101) at one outer end, and each comprising a rear wheel (141) at their other outer end; wherein said first and second rear wheel frame element (104) is each pivotably connected to respective opposite outer lateral ends of said central frame element (101) around respective third and fourth axes, which third and fourth axes extend mutually substantially parallel and substantially perpendicular to said first and second axes; such that a pivoting movement of said front wheel frame (102) element and said push bar connector frame element (103) from the unfolded state towards each other in the folded state results in said first and second rear wheel frame elements (104) being pivoted from the unfolded state towards each other in the folded state, and vice versa.

Known vehicles, e.g. used for the sport of golf, which are configured combined for riding along and to be pushed with motorized support, exclusively comprise a steerable, rigid frame, causing the vehicle when positioned on the side of a slope to tilt parallel to the slope plane, consequently resulting in a disadvantageous, safety-relevant tilting moment. For improved driving safety, it should be possible to tilt the vehicle sideways. The vehicle according to the invention can be used in at least two operating modes. In the ride-along mode, at least a second and/or third vehicle component can be moved by the operator or an automatic, thus causing the vehicle to tilt sideways. This enables a carving effect and the tilt compensation as well as a straight-ahead drive at least in side slopes and inclines. In the push mode, the male/female user walks behind or beside the vehicle, and at least two vehicle components and/or parts thereof are located in a position, relative to each other, different as compared to the position in the ride-along mode. The versatile embodiment variations make it possible to use it as a golf vehicle, as well as a recreational-/, shopping-/, transport-/, industrial-/, construction site vehicle, and as a vehicle for the transport of senior and handicapped persons, for exploration and military purposes, for mowing, as an agricultural vehicle, as gardening appliance and as a child carrier.
