The expansion segments roll on rollers removably affixed to the upright members. The portable structure includes three positions, a transport position wherein large wheels or skids are suppled for easy manipulation of the device, an expansion segment wherein the expansion segments are extended or collapsed using smaller wheels.

Abstract: A folding tent frame for collapsible tents includes upright pole sets, fixed couplers, stoppers, movable couplers and traverse frame members. Specifically, each stopper is provided on the uppermost pole of the upright pole set at a position lower than the fixed coupler so as to prevent the lower pole of the upright pole set from moving up beyond the stopper and so that the movable coupler is slidable over the stopper and the lowest pole of the upright pole set, and is kept from moving up beyond the stopper. The lower pole is larger than the upper pole in cross section. The structure of this folding tent frame provides improved strength and stability.

Abstract: A mobile canopy system providing shelter from the sun, rain, and wind. The canopy system contains at least two canopy system sections, each containing one centrally located support structure. A truss system is attached to the support structure, perpendicularly extending the length of the canopy system section. Canopy framing systems are perpendicularly connected to, and intervally spaced along, the truss system. Cross bars are perpendicularly connected to the ends of the canopy framing systems, extending the length of the canopy system section. The canopy lies in an inclined plane, suspended from the cross bars, providing adequate clearance for underlying activities including golf. The inclined canopy, suspended below the truss system and canopy framing systems, provides absorbing and deflective protection to the user from errantly hit objects, whereby the canopy absorbs the force of the errant object and deflects the object out and away from the participant under the canopy system.

Abstract: A controller for wheeled vehicles includes a mechanism which selectively shifts the vehicle between a mobile and a stable state. The vehicle may be a walker for easing an operator's efforts in walking and includes a selectively actuable stabilizer which fixes the position of the walker or releases it for rolling motion, thus providing a stable state or a mobile state, respectively. An actuator such as a button, pressure sensor, or lever, electrically and/or mechanically actuates a stabilizer brake mechanism to engage or release the brake and thereby allow the walker's mobility to be controlled when the actuator operates the brake to stabilize or to slow the motion of the walker. Preferably, lift applied to the vehicle itself releases the brake and allows mobility. The actuator may control an electrically actuated braking mechanism, in response to a sensor such as a strain gauge that may be adjusted to the needs of the patient; alternatively, lifters may be provided to act in response to the lifting force.
