Abstract
An improved vehicle hose retraction system is disclosed having a dual roller configuration which permits the hose to follow a smooth S-shaped path during extension and retraction, thereby maximizing the hose storage capacity of the system and avoiding kinds and abrasion to the hose. The axis of each roller is oriented so as to be generally perpendicular to the plane of the housing of the retraction system to minimize hose friction and wear. The housing is also provided with an angled hood which presents the free end of the hose in a position that facilitates connection. In addition, a locking mechanism is disclosed which prevents rotation of its members under vibrational conditions.
Claims8
A hose retraction system comprising:
- a housing for the storage and protection of a plurality of hoses, said housing having front and rear ends, said housing having minimized dimensions in order to minimize its weight, whereby said hoses are compactly stored therein, each of said hoses comprising a first loop, a second loop, and a distal end terminating at a connector positioned outside of said housing at an end of said housing opposite from said second loop;
- a plurality of first storage rollers mounted within said housing in a fixed relationship thereto, each of said first storage rollers receiving a first portion of one of said plurality of hoses so as to define said first loop of said hoses when said hoses are retracted within said housing;
- a plurality of second storage rollers mounted to said housing by way of a retraction spring, said second storage rollers providing a means for selectively allowing said distal end of said hoses to be drawn out of said housing while taking up any slack in said hoses so as to compactly store said hoses within said housing, each of said second storage rollers receiving a second portion of one of said plurality of hoses so as to define said second loop of said hoses when said hoses are retracted within said housing;
- a first change of direction roller extending substantially across said housing, said first change of direction roller being positioned substantially parallel with said front and rear ends of said housing and being slidably engageable with a third portion of each of said plurality of hoses when said hoses are retracted within said housing;
- and
- a plurality of second change of direction rollers, each of said second change of direction rollers being engageable with a fourth portion of one of said plurality of hoses proximate to said distal end of said hoses when said hoses are retracted within said housing.
A hose retraction system, comprising:
- a housing for the storage and protection of a plurality of hoses, each of said hoses having a first loop, a second loop and a distal end terminating at a connector;
- a plurality of first and second storage rollers mounted within said housing for receiving said first and second loops of said hoses, said plurality of first and second storage rollers selectively allowing said hoses to be drawn out of said housing while taking up any slack in said hoses so that said hoses are compactly stored within said housing;
- a first change of direction roller engaging a segment of each hose, said first change of direction roller allowing said segment of said hoses to change direction at an angle with respect to said second loop;
- and
- a plurality of second change of direction rollers for allowing said distal end of said hoses to change direction at a second angle with respect to said first angle, whereby frictional forces on said hoses proximate to said distal end of said hoses are distributed over both of said first change of direction roller and said plurality of said second change of direction rollers in order to minimize friction and wear on said hoses, thereby prolonging the life of said hose.
