Various embodiments of a collapsible stroller configured to form at least a compact collapsed configuration are described. In some embodiments, the collapsible stroller includes a foldable frame assembly including a top frame pivotably coupled to a bottom frame such that the top frame is allowed to pivot along a longitudinal plane of the foldable frame assembly. The foldable frame assembly can include first strut assemblies pivotably coupled to the bottom frame at respective angled joints. The angled joints can each include a first axis of rotation that is angled relative to the longitudinal plane such that the strut assemblies pivot towards the longitudinal plane as the top frame pivots towards the bottom frame for forming the collapsed configuration. In some embodiments, the foldable frame assembly further includes a suspension system that also can pivot towards the longitudinal plane when the foldable frame assembly forms the collapsed configuration.

A cart handle and a baby cart in which cart handle includes a fixed member; a handle body rotatable relative to the fixed member; an engagement part having a first portion that non-rotatably engages the handle body and slidably engages the handle body, and having a second portion that non-rotatably engages the fixed member; and an operation part that is actuated to alternately displace the engagement part to an unlocked position, wherein the second portion is not in engagement with the fixed member, thereby permitting rotation of the handle body relative to the fixed member, and displace the engagement part to a locked position, wherein the second portion engages the fixed member, thereby preventing rotation of the handle body relative to the fixed member.

A stroller and foldable frame assembly for a stroller includes a locking mechanism adjustable between a locked position and an unlocked position. The locking mechanism is configured to releasably lock the foldable frame assembly in its use configuration and/or storage configuration by releasably and internally locking at least one of a respective swivel joint assembly of the frame assembly. The locking mechanism includes an actuation element configured to adjust the locking mechanism between the unlocked and the locked position that is arranged spaced apart transversely to a swivel axis of the respective at least one internally lockable swivel joint.

The present disclosure relates to a stroller comprising: a sheet portion including a sheet; a support frame including an upper support frame supporting the sheet, a lower support frame rotatably connected to the upper support frame by a hinge portion, and a frame support that maintains a fixed state between the upper support frame and the lower support frame; and a moving structure to which the support frame is detachably connected, the moving structure including a guide frame that allows the lower support layer to fold and support and is extended in the length direction, a drive frame including a rear wheel coupling portion having a front wheel coupling portion connected in a ‘¬’ shape to the front part of the guide frame and a rear wheel coupling portion having coupling shaft portions formed on both sides of the rear end of the guide frame, a front wheel supported by a support fork to be installed on the front wheel coupling portion, and a rear wheel installed on the rear wheel coupling portion through a rear wheel connecting shaft.

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.

A foldable personal such as a tricycle which can be convertible into a stroller, is configured for accommodating a child therein and for preventing, when desired, the child from being able to steer the vehicle, vehicle having an operational state and a storage state, in which it can take an extremely compact form. The vehicle has a longitudinal axis lying in its vertical plane of symmetry and having a horizontal reference plane perpendicular to the plane of symmetry, and it takes its compact form in the storage state both in the direction along its longitudinal axis and in the directions perpendicular to this axis both along the plane of symmetry and perpendicular to the plane of symmetry.

An animal mobility device to be used with an animal who lacks full functional use of its rear legs, providing the animal with two modes of operation, with the first mode of operation being active, whereby the animal propels itself by its front legs while having its rear portion supported by the device, and with the second mode of operation being passive, whereby a human operator propels the device while the entirety of the animal is supported by the device.
