Title: Hose winding apparatus and method
Inventor: SCOTT BLAYNEY S
IPC: B65H75/40
Filed: 1992-02-06
Abstract: HOSE WINDING APPARATUS AND METHOD            ABSTRACT OF THE DISCLOSURE           Hose winding apparatus comprises a first portion having a body and a first handle extending therefrom, and a second portion having a reel portion and a second handle cooperating with the reel portion.  Each portion has reel journalling structure for journalling the first and second portions  for relative rotation about a reel  axis.   A latching structure releasably latches together the first and second portions to permit the said relative rotation without unintentional separation of the first and second portions.    A wound-up  hose  coil  is  retained  tightly wound-up after the removal from the reel portion by fitting a resilient band to extend across opposite locations of the reel portion, and winding the hose onto the reel portion with a first face of the wound-up hose being adjacent a first length of the band.  This is followed by drawing and stretching a second length of the band from the reel, and positioning the second length closely adjacent a second face of the coil.   This permits the wound-up coil to be drawn from the reel portion along an axis of rotation thereof,  without  unwinding,  for  ease  of  storage  and transportation, and to permit re-use of the apparatus.
