Abstract: A retractable skate and method using armatures that extend for skating and retract for walking. It is preferred that the armatures may be locked into position. It is also preferred that the armatures fasten to a pair of wheels, a frame holding a configuration of wheels, or an ice blade.

Abstract: A vehicle chassis having substantially all of the mechanical, electrical, and structural componentry necessary for a fully functional vehicle includes at least an energy conversion system, a steering system, and a braking system. The chassis is configured for matability with a variety of different types or styles of vehicle bodies. Various prior art mechanical control linkages between a driver and controlled systems are replaced with non-mechanical control signal transmission components. Fuel cell technology is also implemented. The chassis may also include an electrical connector operably connected to the fuel cell and configured to transmit electrical energy from the fuel cell to an offboard system that consumes electrical energy. Chassis may be stacked and/or have interconnected fuel cells to increase electrical energy output.

Abstract: A transport device for hauling a load having a front axle with a pair of wheels and a rear axle with a pair of wheels. Four vertical hydraulic cylinders are provided, each cylinder having a bottom end supported on one of the axles adjacent a wheel, respectively. A pair of yokes are provided. Each yoke has one end supported by the ram extending from the top of one cylinder mounted on the front axle and the other end supported by the ram extending from the top end of a cylinder on the rear axle so that the yokes are parallel to one another and extend from front to rear of the device. A container containing the load is suspended from the pair of yokes. In one version, the device is coupled for transport to a truck. In another version, an engine is mounted on a cantilever frame extending from the rear of the truck controlled by operators in a cab mounted on the front end of the device. In another version, the device has a tongue extending from the front axle and attachable to a truck tractor.

Abstract: A tack cart for transporting and storing tack. The cart includes a conveying member and a storage member mounted thereto. The storage member may be detached from the conveying member and may be mounted onto an independent support located remote from the tack cart. The storage member includes at least one saddle support member which may be detachably mounted on one of the conveying member and the storage member. The cart may further include a detachable bridle support that is receivable on one of the conveying member, the storage member and the independent support.

Abstract: A shock-absorbing apparatus disposed between a binding and a board has a bottom plate for coupling to the board, a top plate or binding platform to receive the binding, and bearing-biasing assemblies coupled between the bottom plate and the top plate. Each bearing-biasing assembly includes a bearing assembly and a biasing assembly where the bearing assembly is disposed coaxially with the biasing assembly. The bearing-biasing assembly is responsive to mechanical energy encountered by the binding platform or the board during use by enabling the binding platform to swivel or pivot from or move along an axis intersecting a top surface of the board.

Abstract: An axle suspension for air-suspended utility vehicles and the like with which the vehicle chassis is supported by a pneumatic spring. The spring is configured as a plunger piston assembly, is preferably cylindrical, and has a plunger piston (6) that is provided for supporting and guiding a pneumatic spring bellows (5). The pneumatic spring bellows is connected via an upper mounting plate (7) to the vehicle chassis resting thereupon and is connected, e.g. via a lower base plate to the top of the plunger piston which is supported, for example, on a leaf spring assembly (1).

Abstract: A creeper (10) includes a main frame (11) which is rendered mobile by caster assemblies (14, 15, 16). A pivot frame (22) is pivotally attached to the main frame (11) and carries a pad section (19). Another pivot frame (28) is pivotally attached to the main frame (11) and carries another pad section (20). A floating frame holding mechanism (50) is provided to maintain a selected pivotal position of the pivot frame (22) relative to the main frame (11), and a frame holding mechanism (34) is provided to maintain a selected pivotal position of the other pivot frame (28) relative to the main frame (11).
