A child stroller apparatus includes a rear leg frame having a first side segment fixedly connected with a first coupling part, a front leg frame having a second side segment fixedly connected with a second coupling part, a handle frame having a third side segment fixedly connected with a third coupling part, the second and third coupling parts being respectively connected pivotally with the first coupling part, a front guard pivotally connected with the first coupling part, a first linking assembly rotationally coupling the second side segment with the third side segment, and a second linking assembly rotationally coupling the front guard with the second side segment. The front leg frame, the handle frame and the front guard are linked and rotatable relative to the rear leg frame during folding and unfolding of the child stroller apparatus.

A wheeled carrying apparatus includes a frame structure including a standing frame, a wheel mount carrying a wheel and pivotally connected with the standing frame, the wheel being rotatable relative to the first wheel mount about a wheel axis, a locking assembly including a wheel mount latch movably connected with the standing frame, the wheel mount latch being engaged with the wheel mount to rotationally lock the first wheel mount with respect to the standing frame, and disengaged from the wheel mount to unlock the wheel mount for rotation of the wheel mount to change an orientation of the wheel axis, an actuating assembly coupled to the wheel mount latch and including one or more linking part, and a release mechanism including an operating part provided on the frame structure that is operable to cause the actuating assembly to pull the wheel mount latch to disengage from the wheel mount.

In an aspect, a pivot joint for a collapsing foot-deck-based vehicle is described, comprising a foot deck, at least two wheels coupled to the foot deck, and a handlebar assembly coupled to the foot deck via a locking pivot joint, also referred to as a locking swivel joint, the handlebar assembly comprising at least one handle, the locking pivot joint having a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels, the handlebar assembly being selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck and a collapsed configuration in which the handle is generally proximal to the foot deck.

A frame adjustable all-terrain stroller apparatus for use along hiking and wilderness trails includes rear wheels attachable at lowermost ends of independently positionable swing arms. Each swing arm is securable independently and each rear wheel is thereby positionable at a different elevation enabling stable operation of the stroller apparatus along sloped surfaces. Each rear wheel includes a stub axle devised to engage interior to an aperture disposed at the lowermost end of each of the pair of swing arms. The rear wheels are securable in each of a first position, exteriorly mounted to the swing arms, and a second position, interiorly mounted to the swing arms, whereby the rear wheel track of the stroller apparatus is variable. No rear axle connecting between the rear wheels is required, so clearance of the stroller apparatus is maintained.

A compact multifunction collapsible stroller and cart which provides increased convenience with its small factor when collapsed. It is able to be reversibly converted from a stroller to a shopping or utility cart. The seat and receptacle of the invention have no rigid connections to the wheeled frame, instead they are suspended in place by non-rigid connections such as cables or wires connecting them to the wheeled frame. The wheeled frame may be telescopic and collapsible, and can be wrapped in the flexible material of the seat or cart receptacle thereby allowing the seat or cart receptacle to act as a carrying bag.

A tricycle operable in a swivel state and a steering state, having a tricycle frame; two rear wheels rotatably connected to the tricycle frame; a front wheel; a handlebar; a wheel fork rotatably connected on one end thereof to the front wheel and connected on a second end thereof to the handlebar via a swivel mechanism; the swivel mechanism comprises: a push button configured to: be pushed down and towards the tricycle frame thereby coupling the handlebar to the wheel fork and allowing a rider of the tricycle to steer; and be pushed down and away from the tricycle frame thereby detaching the handlebar from the wheel fork and allowing the front wheel to swivel; wherein the front wheel swivel rotation axis is different than the handlebar rotation axis.

A folding tricycle, having a first rear frame rotatably connected on a first end thereof with a first end of a first bottom frame; a second rear frame rotatably connected on a first end thereof with a first end of a second bottom frame; the first rear frame rotatably connected on a second end thereof with a first rear wheel; the second rear frame rotatably connected on a second end thereof with a second rear wheel; the first and second bottom frames rotatably connected on second ends thereof with a first end of a front frame; a seat frame rotatably connected on a front end thereof with one of a second end of the front frame and a front bearing member; a front wheel connected with a handlebar through one of the front frame and the front bearing member; first and second support frames connected respectively on first end thereof with the first and second rear frames and configured to stabilize the tricycle in an unfolded position; and a locking mechanism configured to lock the tricycle in an unfolded position; the tricycle is configured to be folded into a position where the front wheel is positioned in between the first and second rear wheels.

The equipment (1) includes: a median front pillar (2a), provided with at least one front wheel (4) at its lower end; a seat (7) located at the upper end of the front median pillar (2a); two pivotable legs (5), pivotally connected, by a front end, to a lower part of the median front pillar (2a), and each including a wheel (6) at a rear end; a slider (18) slidably movable along the front median pillar (2a), and two connecting rods (24) connected to the slider (18), on two opposite sides thereof, and connected to the legs (5); the slider (18) is movable between a lower position, in which the connecting rods (24) bring the legs (5) into the unfolding position and an upper position, in which the connecting rods (24) bring the legs (5) into the folding position; and releasable device (30) for holding the slider (18) in the lower position.

A stroller assembly may be configurable as an assembled stroller having selected components defining one of a plurality of potential stroller configurations. The stroller assembly may include a plurality of constituent assemblies. Each of the constituent assemblies may include a plurality of selectable components that, when selected and combined into the assembled stroller, define a corresponding expression of the stroller assembly.

A moving carrier is disclosed. A lower-frame assembly includes a first moving member disposed on the guiding member, a second moving member disposed on the guiding member, an elastic member disposed corresponding to the guiding member, and a third moving member disposed on the second moving member. A transmitting member of a front-wheel assembly has a guiding groove. One end of the third moving member is disposed in the guiding groove. When the first moving member moves along the guiding member, the first moving member enables the elastic member to store a first energy. When the elastic member releases the first energy, the second moving member drives the third moving member to move and the third moving member pushes the guiding groove to move, so that the transmitting member can drive the front-wheel frame to move toward the lower-frame assembly.
