An expandable car jack includes a vehicle lifting assembly with an upper lifting member, a lower lifting member mechanically coupled to the upper lifting member, and a lifting mechanism capable of moving the upper lifting member to a plurality of raised height positions. A base is coupled to the vehicle lifting assembly and includes a first base support member, a second base support member, and a base support coupler that is operable to selectively couple the first base support member to the second base support member in at least a first coupling position and a second coupling position. The base support coupler selectively mechanically maintains a parallel alignment and a perpendicular alignment of the first base support member and the second base support member when the base support coupler is in the first coupling position, allows the first base support member and the second base support member to freely move between the parallel alignment and the perpendicular alignment when the base support coupler is in the second coupling position, and remains mechanically coupled to at least the first base support member in the first and second coupling positions so that the first base support member cannot move with respect to the second base support member without a mechanical alteration to the base support coupler prior to moving either the first base support member or the second base support member.

An articulating wagon frame has an open position and a closed position. The frame has eight corner joints, namely four upper corner joints and four lower corner joints. The four upper corner joints include a right front upper joint, a left front upper joint, a right rear upper joint, and a left rear upper joint. The four lower corner joints include a right front lower joint, a left front lower joint, the right rear lower joint, and a left rear lower joint. Four linear joints include a right middle upper joint, a left middle upper joint, a left middle lower joint, and a right middle lower joint. Six vertical supports include a right front vertical support, a left front vertical support, a right middle vertical support, a left middle vertical support, a right rear vertical support, and a left rear vertical support.

A collapsible dolly assembly includes a pair of frames that are each selectively urged between a deployed position and a collapsed position. A pair of rear wheels is rotatably coupled to the frame to roll along a support surface. A pair of front wheels is rotatably coupled to the frame to roll along the support surface. A dolly is hingedly coupled to the frame to support an object thereby facilitating the object to be transported along the support surface. A pair of skid units is movably coupled to an associated one of the frames. Each of the skid units is selectively positioned in a deployed position. In this way each of the skid units frictionally engages a staircase thereby facilitating the object to be urged upwardly and downwardly along the staircase. A braking unit is movably coupled to the frame to selectively engage the staircase when the skid unit is positioned in the deployed position. Thus, the braking unit retains the object at a selected point along the staircase.

A collapsible cart assembly having a framework with two brackets. The two brackets have first arms, second arms and third arms. A rear leg frame section is rigidly affixed to the first arms. A front leg frame section that is pivotably connected to the second arms. A handle frame section is pivotably connected to the third arms of the brackets. Slides are disposed on the rear leg frame section. A first set of linkages connect the slides to the front leg frame section. A second set of linkages connect the slides to the handle frame section. The slides and linkages move the front leg frame the handle frame between an open configuration and a closed configuration.

A wagon is adjustable between a collapsed configuration, an intermediate configuration, and an expanded configuration. The frame has a vertical pole assembly arranged at each of the four corners of the frame. Each of the vertical pole assemblies comprises an extension member telescopically arranged with a fixed member and a slider operatively slidingly connected with the fixed member. When the frame is altered from the expanded configuration to the intermediate configuration, the slider of each vertical pole assembly moves away from the distal end of the fixed member toward the proximal end of the fixed member and the extension member moves from the raised position to the lowered position. When the frame is altered from the intermediate configuration to the collapsed configuration, the extension member moves from the lowered position to the raised position with the slider at or adjacent to the proximal end of the fixed member.

A collapsible cart may include a handle, a first supporting frame, and a second supporting frame. In one embodiment, the handle is movably secured at the first supporting frame, and the first supporting frame and the second supporting frame are connected with a connecting member. The connecting member may include a plurality of connecting units. In one embodiment, the collapsible cart further includes a fabric secured at a receiving space created by the supporting frames and the connecting members on both sides. It is important to note that when the cart is fully unfolded, the first and second connecting units are substantially perpendicular to the second supporting frame and the first supporting frame respectively to strengthen the connecting member.

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.

A portable folding wagon includes a wagon frame with a folding frame and wheels. The folding frame has four scissor mechanisms, each mechanism has at least a scissor unit. The top portions of two adjacent scissor mechanisms are rotatably connected by a top connecting base, the bottom portions are rotatably connected by a bottom connecting base; the bottom connecting base is rotatably connected to a support rod, the bottom connecting base is disposed with a through hole, the top periphery of the through hole of the bottom connecting base extends upwardly to form a surrounding wall for the support rod to pass through, the bottom end of the support rod passes through the surrounding wall and the through hole and connects to the wheel, the top end of the support rod is rotatably connected to a sliding connecting piece, the sliding connecting piece is slidably connected to the scissor unit.
