A stilt comprises a floor platform, a shoe platform, parallel supports extending between the platforms, a leg support extending above the shoe platform, and a yoke connecting the leg support to the shoe platform. The pair of parallel supports is substantially vertically mounted supports pivotally connecting the floor platform and the shoe platform. The vertical supports are spring-biased so as to maintain the vertical supports and the platforms in a parallelogram configuration. The leg support is mounted to one of the vertically mounted supports and to the shoe platform. The mounting includes a capturing bracket for engaging the lower end of the leg support. The yoke engages the leg support at the attachment to the shoe platform. A key closely engages depressions in the yoke and the leg support to resist twisting of the leg support.

A leg attachment assembly for a stilt device of the type used to support a user above a base surface. The stilt device has a shoe plate supportable above a floor plate via front and rear struts and a leg attachment assembly configured to attach a leg of the user to the stilt via a leg attachment mechanism and a leg pole. A leg pole attachment assembly includes an exterior clamp bracket that forms an open-box with a c-shaped channel into which is disposed an interior swivel clamp. The interior swivel clamp has a base portion that swivels over a limited range of motion within the c-shaped channel and is affixed to a side portion of the exterior clamp bracket using a horizontally extending fastener. Opposing flanges of the swivel clamp extend around the leg pole and are interconnected using a second fastener that extends orthogonally to the first fastener.

A height-adjustable apparatus using a spring to urge forward and rearward undulating whippy locomotion is disclosed. A hand-crawling embodiment having a hand-glove assembly affixed to a base assembly enables users to engage in all-fours crawling locomotion while the body is conventionally situated in a two-legged orientation. One embodiment includes a forearm support bracket mounted at either a permanent or adjustable wrist angle. An internal stabilizer cylinder retainer is also provided to reduce inward pivoting of the internal stabilizer cylinder retainer in the direction of the opposite hand while permitting outward pivoting toward the outside of the device, and front-to-back pivoting toward the front side or backside of the device. A similar foot-bounding embodiment enables walkers, joggers, runners and jumpers to engage in forward and backward whippy locomotion. A crutch embodiment having a similar base assembly enables crippled or injured users to likewise engage in whippy locomotion.

A pneumatic synchronous lifting stilt device includes a pneumatic driving assembly, a left stilt assembly and a right stilt assembly. The stilt assembly includes a fixed frame, a lifting platform assembly, and a cylinder body, the lifting platform assembly is mounted on the cylinder body, the fixed frame is provided with an inner rod, the cylinder body is sleeved over the inner rod, and the pneumatic driving assembly is configured outside the cylinder body. The fixed frame includes a connecting platform and a supporting platform, the connecting platform is located on one side of the supporting platform, a lower end of the inner rod is connected to the connecting platform; and the supporting platform is located directly below the lifting platform assembly. The stilt device achieves synchronous adjustment, has a simple structure, and is balanced in force, comfortable and safe to use.
