Abstract
A self-retracting air compressor assembly includes a motorized pump device that drives in opposing directions. A reservoir tank is in fluid communication with the pump device and stores air pumped by the pump device. The air compressor includes a cord assembly that supplies air and electrical power from the pump device. The air compressor assembly pumps air when the motor is driving in a pumping direction, and self-retracts the cord assembly when the motor is driving in a winding direction.
Claims22
A self-retracting air compressor comprising:
- a pump device having a motor, the motor configured to drive in a pumping direction and in a winding direction;
- a reservoir tank in fluid communication with the pump device;
- and
- a cord assembly configured to supply air and electrical power from the pump device, the cord assembly having a first end attached to the pump device, the cord assembly comprising a fluid hose in fluid communication with the pump device, a power cord in electrical communication with the pump device, and a jacket that surrounds at least a portion of the fluid hose and the power cord;
- wherein the pump device is configured to pump air during operation of the motor in the pumping direction, and the cord assembly is configured to self-retract by winding around an outer periphery of the reservoir tank during operation of the motor in the winding direction.
An air compressor assembly comprising:
- an air compressor having a central axis, the air compressor comprising:
- a pump having a motor, the pump positioned about the central axis of the air compressor, the motor configured to drive in a pumping direction to effect the pump to pump air and in a winding direction;
- and
- a reservoir tank in fluid communication with the pump, the reservoir tank having a torus shape that circumscribes the pump;
- a cord assembly having a first end attached to the air compressor and a second end, the cord assembly a configured to supply at least one of air or electrical power from the air compressor;
- a spool surface surrounding at least a portion of the air compressor, the spool surface configured to receive a wound portion of the cord assembly;
- a drive system configured to control winding of the cord assembly about the spool surface;
- and
- a frame positioned about the air compressor, the frame having a contact surface in proximity to the drive system;
- wherein the drive system is configured to engage with the contact surface of the frame in response to the motor operating in the winding direction,
- wherein operating the motor in the winding direction effects rotation of the spool surface about the central axis, thereby winding the cord assembly about the spool cover, and
- wherein the drive system is configured to disengage from the frame in response to the motor operating the pumping direction.
