A foldable cart frame has a folding mechanism, a connecting seat, two rear legs, and a handle unit. The folding mechanism has a base seat, at least one guiding rod connected to the base seat, a sliding seat slidably disposed on the at least one guiding rod, and a linkage assembly moveably connected to the sliding seat. The connecting seat is movably disposed on the folding mechanism. The two rear legs are disposed on the base seat. The handle unit is moveably inserted through the base seat, is fixedly connected to the sliding seat, and can drive the sliding seat and the connecting seat to move. The two rear legs are driven by the linkage assembly. The foldable cart frame can be folded and expanded conveniently and quickly. The connecting seat and its connecting components can form a stable supporting structure after expanding.

The present invention provides a foldable baby carriage frame comprising a handle assembly, a front leg assembly, a front leg support assembly, a rear leg assembly, a rear foot connecting assembly, a horizontal support rod and a torsion spring. The torsion spring is provided at the connection between the front leg support assembly and the rear leg connection assembly, and the torsion spring controls the opening and closing of the front leg support assembly and the rear leg connection assembly by the rotation. When downward force is applied to the rear leg assembly, the rear leg assembly pivots downward with the torsion spring as the pivot point, so that the front leg support assembly and the rear leg connecting assembly realizes the effect of automatic folding. After the downward force is released, the front leg support assembly and the rear leg connecting assembly return to the state when the baby carriage is in use.

A transport dolly includes a base and a tongue rotatably mounted to the base. At least one support is mounted to the base. A first cable guide is coupled to the at least one support. A lever is rotatable between a first orientation and a second orientation. A cable has a first portion attached to the tongue. The cable extends from the tongue to the first cable guide, then to the lever. The lever pulls on the cable when the lever is rotated from the first orientation to the second orientation, so as to decrease a distance between the cable first portion and the first cable guide, thereby rotating the tongue from a lowered orientation to a raised orientation. A spring mechanism exerts a force on the lever to prevent rotation of the lever from the second orientation to the first orientation when the tongue is raised.

A foldable cart includes a handle portion, a foldable frame movably connected to the handle, and one or more wheels for rolling on a surface. In an unfolded (in-use or open) condition, the foldable frame constructs a holding-space defining a receiving cavity therein for carrying items, and the action of unfolding the frame automatically deploys wheels to enable immediate use of the cart by the end-user or customer. In a folded (storage or closed) condition, the carts' frame folds to occupy a smaller space in one or more spatial dimensions, and the automatically deployed wheels turn to occupy smaller total space in one or more spatial dimensions. In the folded condition, the cart is easy to store in a small space (e.g. in a small closet, under a bed, etc.) or transport (e.g. in the trunk of an automobile, vehicle, airplane, train, ship with a courier, etc.).

A child stroller apparatus includes a rear and a front leg frame respectively having a first and a second side segment, a handle frame having a grip portion and a third side segment respectively connected fixedly with a first and a second joining part that are pivotally connected with each other, a latching mechanism for locking the rear and front leg frames and the handle frame in an unfolded state, and a latch carried with the third side segment. The latch can engage and disengage the first joining part to lock and unlock the grip portion relative to the third side segment. Moreover, a linking part couples the latch to the rear leg frame or the front leg frame so that a folding rotation of the handle frame relative to the rear leg frame causes the latch to disengage from the first joining part.

A baby carriage having lateral articulated joints, each lateral articulated joint having a connection for a leg of a push bar, a front wheel strut and/or a rear wheel strut, of which at least two elements of the baby carriage are pivotable relative to one another about an articulated axis extending transversely with respect to the travel direction of the baby carriage. The at least two elements of the baby carriage being connected at an articulated joint, so as to be pivotable relative to one another, coupled together in a rotatably fixed manner so as to not be pivotable to one another. The lateral articulated joints being configured to be selectively released and selectively fixed, whereby to permit selective pivoting of some elements of the baby carriage relative to other elements of the baby carriage.

The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted V-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.

The disclosure claims a multi-functional frame for an oven. The multi-functional frame for the oven mainly comprises a base frame, a platform, a pedal, a handle and a protective cover, wherein the pedal is arranged at the lower end of the base frame, the platform is arranged at the upper end of the base frame, the handle is installed on the side wall plate of the platform, and the protective cover is installed at the upper end of the platform. The multi-functional frame for the oven is reasonable and simple in structure. The multi-functional frame for the oven has characteristics of low packaging and transportation costs, convenient and easy use and assembly for a user, and time saving, labor saving and worry saving when use.

The stair-climbing stroller is a baby stroller with retractable front and rear wheels for use on flat travel surfaces and a pair of tracks for use on inclined travel surfaces including, but not limited to, staircases. The front wheels are coupled to a pivoting front wheel support shaft and the rear wheels are coupled to a pivoting rear wheel support shaft. A wheel retract motor located on the underside of the stroller may cause a retraction drive shaft to pivot the front and rear wheel support shafts, retracting the wheels. When the front and rear wheels retract, the stroller may be lowered such that the left and right track rest on the ground. Left and right track motors may then be used to drive the stroller up an inclined travel surface using the tracks.
