The present disclosure provides a baby stroller frame, comprising: a front leg rod, a front wheel connected to a lower end of the front leg rod; a rear leg rod, a rear wheel connected to a lower end of the rear leg rod, an upper end of the front leg rod being rotatably connected with an upper end of the rear leg rod; a handle set comprising a rear link rod, the rear link rod is rotatably connected to the rear leg rod at a position that is on the rear link rod and is close to an lower end of the rear link rod; a front support rod comprising a first link rod and a second rod slidably connected to the first link rod, the first link rod being rotatably connected to the upper end of the rear leg rod or to the upper end of the front leg rod, the second link rod being rotatably connected to the rear link rod; a seat rod having one end rotatably connected to the rear link rod and one other end rotatably connected to a middle portion of the front leg rod; the stroller frame according to the present disclosure is provided with an easy folding mechanism that allows for a quick folding configured to realize one-click quick folding and automatically standing, thereby enabling convenient operations of taking away and putting down, meanwhile reducing the production cost and improving the user experience.

A child seat is detachably mounted on a foldable stroller comprising a stroller handle and front and rear leg portions. The stroller handle is foldably connected to the rear leg portion. The front leg portion is foldably connected to the rear leg portion and has a first adaptor. The child seat includes a first pivot and a seat frame having a lower seat portion and an upper seat portion foldably connected to the lower seat portion. The first pivot is pivotably connected to the lower seat portion and detachably mounted on the first adaptor. When the front leg portion and the stroller handle are folded relative to the rear leg portion, the upper seat portion is folded on the lower seat portion, and the lower seat portion is folded on the front leg portion via the first pivot together with the upper seat portion.

A collapsible cart frame includes four vertical bars defining four corners of the cart frame, four scissor linkages extending between different pairs of the vertical bars to define four sides of the cart frame and four wheels mounted at the bottom ends of the vertical bars. The scissor linkages are configured to expand and collapse independently from one another. Each of the lower scissor ends are attached to a pair of vertical bars at a fixed height and each of the upper scissor ends are slidably attached to the pair vertical bars. Height defining elements selectively define heights of at least one of the upper scissor ends of each of the scissor linkages.

A folding dolly system, a base unit of a folding dolly system, and methods of forming and using a folding dolly system are presented. A folding dolly system comprises a plurality of interconnectable base units connected to form a substantially planar holding surface, each base unit comprising a first edge with a number of knuckles configured to form a joint, a second edge with a number of knuckles configured to form a joint, and a surface forming a portion of the holding surface.

A stroller includes a front leg, a rear leg rotatably connected to the front leg, a handle assembly and a locking component. The handle assembly is rotatably connected to one of the front leg and the rear leg. The locking component is movably disposed on the handle assembly. The locking component can be driven to disengage from the one of the front leg and the rear leg for allowing the rotating movement of the handle assembly during a rotating movement of an upper handle portion of the handle assembly. Furthermore, the rotating movement of the handle assembly can drive the other one of the front leg and the rear leg to rotate. Therefore, the entire stroller is allowed to be folded easily and compactly by disengaging the locking component and then rotating the handle assembly, which brings convenience 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.

Embodiments disclosed herein are generally related to children's stroller systems and more particularly to systems, methods, and apparatus for providing a compact folding wagon-style stroller. In at least one embodiment, a compact folding wagon-style stroller can be provided. The stroller can include a stroller frame including a handle that can be folded into a collapsed position and a group of one or more tubes coupled to one another via a floating hub, wherein the floating hub includes a slidable release grip. When the slidable release grip is actuated by a user, the group of one or more tubes are permitted to rotate from an operable configuration to a closed or folded position.

The present invention discloses a folding cart, which comprises a left frame, a right frame, plurality of platforms, a left connecting rod, a right connecting rod, a guide rod, a sliding sleeve, a pressing member, a moving block and an elastic member. The sliding sleeve, disposed on the guide rod and slidable up and down relative to the guide rod, has a limiting hole opposite to the second opening of the guide rod. The pressing member has a first slope. The moving block has a second slope and a limiting protrusion. By the slope sliding between the pressing member and the moving block and the sliding of the sliding sleeve along the guide rod, the sliding is smooth, with low friction. Therefore, not too much force is required and the operation is thus easier.

A collapsible cart frame includes four vertical bars defining four corners of the cart frame, four scissor linkages extending between different pairs of the vertical bars to define four sides of the cart frame and four wheels mounted at the bottom ends of the vertical bars. The scissor linkages are configured to expand and collapse independently from one another. Each of the lower scissor ends are attached to a pair of vertical bars at a fixed height and each of the upper scissor ends are slidably attached to the pair vertical bars. Height defining elements selectively define heights of at least one of the upper scissor ends of each of the scissor linkages.

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.
