First Claim
1. An apparatus for extending and retracting a vacuum cleaner hose comprising:
- a) first and second spaced hose guides, said guides having axially aligned hose receiving orifices;
b) first and second opposed hose drive rollers, said rollers having concave faces together defining a hose receiving nip axially aligned with the orifices of said guides;
c) drive means for reversibly rotating said rollers in opposite directions; and
(d) a pivotable mount supporting said first drive roller, and a mount release, whereby said roller is pivotable between an engaged position and a release position.

Abstract
A central vacuum hose storage unit to be positioned between the studs of a wall having upper and lower storage chambers and a reversible hose drive assembly positioned to deploy a vacuum hose from a stored position in the lower chamber outwardly through the upper chamber. The drive assembly includes a pair of spaced drive rollers each including a toothed gear with a central shaft opening, and a hose engaging member secured to the gear, the periphery of the roller members having opposed concave faces together defining a hose receiving nip, and radially extending, equally spaced, flexible hose engaging segments extending transversely across the concave faces, and a reversible drive means operatively connected to both roller gears.
