Abstract: A support structure including a turntable, support platform, and a set of ramps. The ramps and support platform provide support for a vehicle such as a motorcycle, snowmobile, or the like. The entire apparatus swivels by means of the turntable at 360°, and the apparatus also has a set of retractable wheels which enable the apparatus to be rolled across a horizontal surface.

Abstract: A device and method for shutting off the flow of gas to a structure, such as a residence, when a fire is detected in the structure. The device has a fire detector for providing a status signal to indicate the presence of fire in a structure, an actuator in communication with the fire detector, and a shut-off valve located on a gas line and connected to the actuator. When the status signal is received by the actuator, the actuator causes the valve to close, thereby shutting off the flow of gas to the structure. The device also includes one or more of the following: a secondary electric power source, disturbance prevention circuitry, a shut-off valve position indicator, a manually operated means of closing the shut-off valve, and an alarm indicator for indicating the presence of fire in the structure. The method involves detecting a fire and providing a status signal to an actuator. Then the actuator moves the shut-off valve from an open position to a closed position.

Abstract: A support structure including a turntable, support platform, and a set of ramps. The ramps and support platform provide support for a two-wheeled vehicle. The entire apparatus swivels using a turntable at 360.degree., and the apparatus also has a set of retractable wheels which enable the apparatus to be rolled across a horizontal surface. Also the ramps fold up around the support frame for ease of storage.
