A cart for connecting or attaching to a wheelchair is provided to assist a wheelchair user to more easily collect and move items, such as groceries. In certain embodiments the cart is further defined as a shopping cart.

The invention relates to a new manual cash cassette trolley (1), which is driven manually by the employee/security guard, said manual trolley (1) having a formal structure that greatly facilitates the displacement of the cash cassette, overcoming obstacles that usually cause inconvenience and demand physical strength and attention from the user who handles the cassette container boxes; said manual cash cassette trolley (1) having stoppers (7), spindles (4) on the internal faces of the extensions (6) and a smaller caster (5a) on each of its external faces; among the larger casters (5) positioned inferiorly and the smaller casters (5a) positioned centrally or intermediately, the other portion (2a) of said structure is positioned horizontally and orthogonal to the main vertical portion (2), which is “U” shaped and receives bilateral plates (8); the horizontal portion (2a) of the structure also receives bilateral tubular elements (9) in the form of right triangles; and the external and shorter section (10) of said horizontal portion (2a) of said structure of said cash manual trolley (1) features a handle element (11).

An inclination-adjustable cart includes a loading plate on which an object is loaded and a frame supported and fixed to one side of the loading plate, having a handle on the top side thereof to allow gripping by a hand. Wheels are installed at the front and rear of the lower part of the loading plate to guide the movement thereof. The wheels are divided into a front wheel part and a rear wheel part that may be simultaneously lifted/lowered using a wheel shaft or a support plate coupled to the bottom end of a lifting/lowering means. The top end part of the lifting/lowering means is coupled to the bottom surface of the loading plate. The lifting/lowering means is driven by a control part having a gyro sensor. Objects may thereby be stably or conveniently transported without being separated from the cart loading plate, i.e., a cargo box.

A composite structure having a solid-phase concrete base-substrate component; a mesh component having non-woven solid-phase polymeric strands that are fused together to form a three-dimensional structure having a thickness of at least three millimeters, the thickness being defined as the greatest normal distance between the mesh-component first side and second opposing side, at least a portion of the polymeric strands that make up the mesh-component first side are embedded into and thereby attached to the solid-phase concrete base-substrate component; a substantially planar component having first and second sides, wherein the substantially planar-component first side is attached to the mesh-component second side; and an adhesive-layer component having a first and second surface, wherein the adhesive-layer component first surface is in contact with and attached to the second side of the substantially planar component, and wherein the adhesive-layer second surface is in contact with and attached to a first surface of a polyvinylchloride or polyvinylchloride-containing exterior sheet.

A utility cart including a rectangular base is provided. The utility cart includes at least one handle extending outward and upwards from a short side of the rectangular base and a leg extending down from the short side of the rectangular base on the short side of the handles. The utility cart also includes a first wheel assembly joined to the rectangular base on end opposite to the handles, wherein two wheels and the leg are positioned such that the rectangular base is horizontal with a floor, two holes centered along each long side of the rectangular base, and a first adjustable guard that fits into the two holes.

The present invention discloses a load-carrying device such as a suitcase, a carry-bag and a hand truck, which can ascend and descend stairs without changing the position of the person relative to the device. The load-carrying device is constructed with a main frame which defines a main plane of the device, at least two main wheels, and a support frame which can swing out of the main plane. The support frame is equipped with a caterpillar mechanism and optional bottom wheels. When ascending stairs, the support frame is pushed against the main frame by the edge of the stairs and the caterpillar with a ratchet mechanism helps slide the load-carrying device upward. When descending stairs, the support frame swings down toward the lower step before the main wheels go off the upper step so that the support frame enables soft-landing of the main wheels.

A stair traversing device comprising a payload body for transporting a payload, a step frame, and a mechanism between the step frame and the payload body to move the step frame relative to the payload body along a cyclical path. The mechanism drives a movement of one of the payload body and the step frame along a first segment of the cyclical path from a retracted configuration to an extended configuration, and drives a movement of the other one of the payload body and the step frame along a second segment of the cyclical path back into the retracted configuration. The payload body and the step frame are configured to remain fixedly in position on a stair when the other one of the payload body and the step frame is moved. The mechanism is configured to maintain the relative orientation between the payload body and the stair.

A patient support apparatus for traversing objects supported on ground surfaces. The patient support apparatus comprises a patient support deck, and a base to support the patient support deck from the ground surface. At pair of caster wheel assemblies spaced from each other are coupled to the base for pivoting movement about respective pivot axes cooperating to define a reference plane. A frame guard coupled to the base defines first and second ramp surfaces each disposed at an angle relative to the reference plane. The first ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in a first direction. The second ramp surface is arranged to engage objects before they contact one or more of the caster wheels when the patient support apparatus moves in an opposite, second direction.

A system may include a vehicle having a storage area and a guide rail configured to extend from the storage area. The system may further include a robot having a support portion comprising a placement surface and a base. The robot may also include a plurality of descendible wheels. The robot may also further include a plurality of legs, each connecting the support portion to one of the plurality of descendible wheels.
