A surface walker for human beings consisting of a chassis holding four articulated, movable limbs for walking. Each limb rests on foot, ski or float. Chassis is topped with cushioned seat whereon user lies prone on chest and belly with access to limbs, which are activated with arms and legs. Chassis height and limb length are adjustable. User regulates walking gait, limb stride and motion frequency of limbs. Walker advances on land and water and diverse landscapes. Design incorporates optional computer-controlled power assistance for walker motion and use of mechanical hand for enhanced traction and anchoring effects.

An object of the present invention is to provide an innovative opening-closing tool with extremely high product value. A first half-body 1 having a first operating part 1a on the distal end and a first handle part 1b on the proximal end and a second half-body 2 having a second operating part 2a on the distal end and a second handle part 2b on the proximal end have a cross-over pivot, and a biasing body 3 that abuts the second half-body 2 and provides an open bias on the two handle parts 1b, 2b is provided on the first half-body 1.

A hauler device is disclosed for transporting multiple items across the floor or upstairs with ease. The device is a hard plastic sled equipped with a long, rope-type or flexible handle to pull the sled across the ground or upstairs. The hauler device comprises a body component that is configured in a rectangular (i.e., rectilinear) shape as a sled. The body component is capable of holding multiple items to be transported across the floor or upstairs, such as groceries, retail items, etc. Attached to the body component is a long, cord-type or flexible handle used to pull the sled. Thus, once the body component of the device is loaded with items, a user can transport the items by pulling the handle of the sled in a convenient and less physically taxing manner.
