A sliding method on ice-surface aims at solve the problems of power output and poor durability and the difficulty in large-scale promotion. An ice-surface sliding tool includes a seat board, a U-shaped rod, sliding plates, H-shaped connecting frames, a pushing device, a hand-operated chain wheel and a reversing gear. One end of the upper end surface of the seat board is provided with a backrest. The U-shaped rod is provided on the side wall of the other end of the seat board. The lower end of the seat board is symmetrically provided with two sliding plates in parallel to each other. The sliding plates are connected with the lower end surface of the seat board through the H-shaped connecting frames. The pushing device is rotationally provided between the two H-shaped connecting frames. The hand-operated chain wheel is on the upper end of the U-shaped rod through a support bar.

An assembly and inspection cart for precision equipment includes a frame that has three support portions to support the precision equipment at three points, air float devices attached to the frame at three positions, a rubber roller and a motor that are provided so as to be freely lifted and lowered with respect to the frame, and an air cylinder that lifts and lowers the rubber roller. The air float device floats the frame together with the precision equipment and forms an air layer between the frame and a floor surface. The rubber roller is arranged at a center of the three air float devices and is configured so as to press against the floor with a predetermined force when lowered by the air cylinder in a state where the frame is floated.

An insulated container configured to store cold consumables is disclosed. The container has a body having a curved track wrapping around the body and upon which the body is able to be rolled. The body has an insulated wall encompassing a cavity configured to hold at least ice and consumables.

A lift unit docking system includes a docking rail, a docking rail adapter, and a locking mechanism. The docking rail is configured to provide ingress and egress of a lift unit to and from an overhead rail, and includes a body defining a channel and an adapter receiving opening within the body. The docking rail adapter is repositionable relative to the adapter receiving opening of the docking rail and is configured to transport the lift unit into and out of the channel of the docking rail. The locking mechanism is repositionable between a locked position and an unlocked position, wherein the locking mechanism extends into the channel to block movement of a mounted lift unit toward the adapter receiving opening of the docking rail when in the locked position.

A combination tool that at one end has a knife and at the other end has a three pronged fork. The two sides are separated by a bridge with a loop attached thereto. One side of the tool has a thin hollow sheath that covers the side when not in use whereas the opposing side has a removable, locking handle that covers it when not in use. Both the sheath and the removable, locking handle are wrapped in paracord for use when deploying the tool and for having paracord at hand. A specialized, removable cleat is attachable and removable from the tool that provides notches that are also found on the top edge of the knife end and the top and bottom prongs of the fork end and also to provide a blunt surface that prevents the paracord from being cut when wrapped around the knife blade.

A mechanical steering system for a wheelchair to permit a user's foot to pivotably adjust a pair of caster wheels of the wheelchair is provided. The system includes a platform coupled to a frame of the wheelchair, a foot controller assembly pivotably mounted to the platform and having a foot plate to receive the user's foot and a rod coupled to the foot plate, a drag linkage member coupled to the rod of the foot controller assembly, and a pair of lever arm assemblies pivotably mounted to the drag linkage member, each lever arm assembly having a lever rod coupled to a fork member, the fork member being coupled to one of the caster wheels. Pivotable movement of the foot plate is transferred through the drag linkage member to permit both lever rods of the lever arm assemblies to pivot, thereby enabling simultaneous pivotal adjustments of the caster wheels.
