A handle folding mechanism, a three-fold handle employing the folding mechanism, and a stroller having the same are provided. The folding mechanism includes an intermediate component and a pair of connecting components. The intermediate component includes a tubular casing, a press block, and an unlocking piece. A rear part of the press block passes through a front surface of the casing to extend into the casing, and is movable back and forth. The connecting component includes a tubular housing and an engaging piece. The engaging piece is slidably mounted in the housing. In a locked state, a front end of the engaging piece penetrates into the casing. The unlocking piece has a fixing part, and the fixing part is disposed with a free end extending between a rear end of the press block and the front end of the engaging piece.

The disclosure provides a baby carriage brake mechanism and a baby carriage. The baby carriage brake mechanism includes a frame, a brake drive assembly, linkage assemblies, brake locks and wheels. The brake drive assembly is disposed on the frame. The linkage assemblies are respectively slidably disposed on the frame on both of left and right sides. Both ends of the brake drive assembly are respectively in abutting connection with the two linkage assemblies. The linkage assemblies are coupled to the brake locks. Two wheels are respectively pivotally disposed at both sides of the frame. By driving the brake drive assembly to push the linkage assemblies to act with the brake locks, the brake locks on both sides are engaged with the wheels, thereby locking the wheels on both sides. Therefore, the baby carriage brake mechanism of the disclosure may brake wheels on both sides simultaneously with simple operation.

A swiveling caster wheel system for use on rolling devices such as children's accessories, furniture or equipment, and including a locking system having a locking actuator that is fixed in position regardless of the swivel position of the caster wheel. The system allows a user to access and actuate the caster locking system from a consistent position of the rolling device regardless of the swivel position of the caster wheel, and allows the caster wheel to be covered without blocking access to the locking actuator.

A stroller accessory connects to a stroller to form a double stroller together and is unusable to transport a child when the accessory is disconnected from the stroller. It includes a frame, a connection mechanism reversibly connecting the accessory to the stroller while defining a tilting axis around which the front part of the accessory frame and the rear of the stroller frame tilt freely relative to one another, two pivoting wheels on a rear part of the frame, a pushing member on the frame rear, a control mechanism controlling a rolling blocking of the double stroller, on the frame front that cooperates mechanically with a rolling blocking system, in the stroller, controlling the blocking system, and an actuating member, on the frame rear to be activated by a user standing behind the double stroller, and which is coupled to the control mechanism so as to actuate the latter.

Wheel assembly (200) a self-propelling trolley (100), comprising a wheel (111,112); an electric motor (151,152) arranged to perform a rocking drive pattern; an electric connector (220), arranged to connect the motor (151,152) to a battery (156); and a mechanical brake (230) activatable so that a rotational movement of the wheel (111,112) is limited, The invention is characterised in that the mechanical brake (230) is arranged so that, in an engaged state, the wheel (111,112) can turn freely in relation to the trolley (100) across a ground distance of between 5 and 20 cm between a first rotary limit position and a second rotary limit position. The movement limitation is provided by several elongated concentric tracks interacting with a pin.

A transportation apparatus reconfigurable between at least two modes of operation. Each mode of operation comprises a mode of transport. A first mode of operation comprises a stroller, push-chair or perambulation (pram) mode. A second mode comprises a velocipede mode, such as a tricycle, bicycle and/or quadricycle mode.

A convertible stroller assembly may be convertible between a single-occupant configuration and a dual-occupant configuration. The convertible stroller assembly includes a stroller frame being convertible between a laterally contracted configuration and a laterally expanded configuration. The assembly further includes a plurality of rear wheels coupled to the stroller frame. The assembly further includes a front wheel coupled to the stroller frame. The convertible stroller assembly is convertible between (i) a single-occupant configuration in which the stroller frame is in the laterally contracted configuration with the rear wheels being separated by a first spacing, and (ii) a dual-occupant configuration in which the stroller frame is in the laterally expanded configuration with the rear wheels being separated by a second spacing greater than the first spacing.

A convertible stroller assembly may be convertible between a stroller configuration and a trailer configuration. The assembly includes a stroller frame including a pair of laterally opposed hubs. The assembly further includes a plurality of wheels coupled to the stroller frame and including at least one removable front wheel. The assembly further includes a seat frame adjustably coupled to the stroller frame. The seat frame is adjustable relative to the pair of laterally opposed hubs between a first position and a second position lower than the first position. The assembly is convertible between (i) a stroller configuration in which the front wheel is coupled to the stroller frame and the seat frame is in the first position, and (ii) a trailer configuration in which the front wheel is absent and the seat frame is in the second position having a lower center of gravity than the first position.
