A camp system has: a plurality of sleds spaced from one another about a ground surface; and a tarpaulin secured in a deployed position between the plurality of sleds and defining an enclosed interior camping area. A method of use includes: arranging a plurality of sleds at a camp site; and deploying a tarpaulin to or over the plurality of sleds to form an enclosed interior camping area between the plurality of sleds. A passive sled has: a hollow tub base; a camper housing with side walls and a roof mounted over the hollow tub base and defining an enclosed interior sleeping area with a bed within the interior sleeping area; and a tow mount at a front end of the passive sled.

A suspension system for skateboards that provides a low profile, high strength suspension system to support a typical roller skate which incorporates one independent and/or offset style suspension and one offset style suspension which includes a flat plate next to a cover with apertures; two support posts secured and configured perpendicularly to the flat plate, where each post has either a drive stud at one end and an aperture and bearing at an opposite end to the flat plate and drive stud; a torsion arm with a socket to connect to the drive stud; and a hub base that encircles the torsion arm opposite the socket which secures the hub base to the torsion arm while the hub base is removably secured to a stub shaft; a way to attach the flat plate and a second way for removably connecting the cover to the skate base plate.

One or more devices are provided that are configured to detachably engage within a modular system. The one or more devices are expandable to provide a surface to perform work.

A packaging supporting frame for a spring mattress includes two transverse frames, two longitudinal frames, and rollers. Each of one or more bottom supporting frames is configured to be rotated to form an angle between 0and 90with a corresponding one of the two transverse frames. When the one or more bottom supporting frames are rotated perpendicular to the two transverse frames, two ends of each of the one or more bottom supporting frames are respectively connected to the two longitudinal frames. A length of each of the two transverse frames in a transverse direction is greater than or equal to twice a length of each of the two longitudinal frames in a longitudinal direction, and the rollers are arranged at the bottoms of the two transverse frames or bottoms of the two longitudinal frames.

A stationary platform for supporting a supply transport device is provided. The stationary platform includes a frame having at least two longitudinal sides, a first end and a second opposing end, and a top surface and a bottom surface, and a plurality of legs extending from the bottom surface of the frame to support the supply transport device on the frame. The supply transport device is slidably received on the top surface of the frame. A wheel base assembly having a cleaning device for contacting a bottom surface of the supply transport device, to remove dirt and debris from or to disinfect the supply transport device, is also provided.

A transportation cart configured to transport video projection screen cases comprises a base frame for supporting a video projection screen case; a plurality of ground engaging units for supporting the base frame from a ground surface; a containment frame located a distance above the base frame and connected thereto; and a first and second strap configured to secure cargo. The transportation cart is also configured to transport a plurality of multipurpose tables and comprises a base; a plurality of ground engaging units for supporting the base from a ground surface; a first and second vertical support extending up from the base.

A lifting assembly for lifting a metal cabinet that has parallel sheet metal walls along its base. The lifting system has a floor jack with wheels and a lift arm. The lift arm supports a lifting saddle. The lifting saddle contacts and lifts the metal cabinet. The lifting saddle has a base plate that is coupled to the lift arm. Adjustable crossbars are mounted to the base plate. The crossbars terminate with slotted heads. The slots are sized to receive sheet metal walls. The slots prevent the sheet metal walls from buckling in the area of contact. The crossbars are adjusted in length to set the slotted heads at a distance apart equal to that of the parallel sheet metal walls. The lifting saddle is maneuvered under the sheet metal walls, wherein the sheet metal walls are received within the slotted heads on the crossbars.
