Abstract
The present invention relates to portable hose carts for handling and storage of flexible hoses, such as garden or air hoses. The cart is primarily constructed of plastic components having a centrally rotatable spool for winding of the flexible hose, an enclosure for supporting the spool, wheels at one end of the base of the enclosure, and a handle assembly for tilting the frame onto the wheels to facilitate moving the device. The handle assembly is telescoping mounted and includes a handle mounted near the top of the handle assembly. The spool is rotatable by either a direct current powered motor or a folding manual crank. Power from the electrical motor is transferred to the spool via an infinitely adjustable torque transfer assembly. When the cover is in the open position, the direct current motor is operationally locked out, and when the cover is rotated into the closed position, the direct current motor is operable. The device may further include a reciprocating guide assembly that operates during rotation of the spool to rewind the hose into a compact configuration.
