Abstract:
1. A retractable reel for flexible tubing comprising: a housing defining an interior cavity and first and second apertures; a first tubing wheel rotatably supported within said housing; a first spring coupled to said first wheel imparting a rotational force upon said first wheel toward a first winding direction of rotation; a first ratchet pawl mechanism coupled to said first wheel for releasably latching said wheel against rotation in said first winding direction of rotation; a first flexible hollow collapsible tube wound upon said first wheel having a first internal end and a first external end, said first external end and a portion of said first flexible tube passing outwardly through said first aperture; a second tubing wheel rotatably supported within said housing; a second spring coupled to said second wheel imparting a rotational force upon said second wheel toward a second winding direction of rotation; a second ratchet pawl mechanism coupled to said second wheel for releasably latching said wheel against rotation in said second winding direction of rotation; a second flexible hollow collapsible tube wound upon said second wheel having a second internal end and a second external end, said second external end and a portion of said second flexible tube passing outwardly through said second aperture; and a rotatable coupler connected between said first and second internal ends said rotatable coupler being constructed to provide independent rotational coupling between said first and second internal ends, whereby said first and second flexible tubes are independently wound upon or withdraw from said first and second tubing wheels respectively without imparting any twist to said first and second tubes.
