A personal mobility device includes a control system including a manually operated actuator, a first forward control valve having an inlet in fluid connection with a source of pressurized gas and an outlet in fluid connection with a first forward port of at least a first pneumatic motor, and a first rearward control valve having an inlet in fluid connection with the source of pressurized gas and an outlet in fluid connection with a first rearward port of the first pneumatic motor. Movement of the manually operated actuator controls actuation of the first forward control valve and the first rearward control valve and thereby flow of gas from the source of pressurized gas to the first forward port and the first rearward port.

Pneumatic powered mobility control systems

A personal mobility device includes a frame, a plurality of wheels attached to the frame and one or more pneumatic motors. Each of the one or more pneumatic motors has a drive shaft in operative connection with at least one of the plurality of wheels. The personal mobility device further includes at least one tank (that is, a storage container) for storage of a pressurized gas in operative connection with the one or more pneumatic motors to supply pressurized gas to the one or more pneumatic motors and a control system in operative connection with the at least one tank and with the one or more pneumatic motors.

Pneumatic powered mobility devices

A wheelchair includes a frame, a seat attached to the frame, a first forward wheel on a first side of the frame and a second forward wheel on a second side of the frame, a first rearward wheel on the first side of the frame and a second rearward wheel on the second side of the frame, a first drive wheel on the first side of the frame positioned intermediate between the first forward wheel and the first rearward wheel and a second drive wheel on the second side of the frame positioned intermediate between the second forward wheel and the second rearward wheel, and actuators to independently control the vertical position of the first forward wheel relative to the frame, the vertical position of the second forward wheel relative to the frame, the vertical position of the first rearward wheel relative to the frame, the vertical position of the second rearward wheel relative to the frame, the vertical position of the first drive wheel relative to the frame and the vertical position of the second drive wheel relative to the frame.
