Abstract
Certain exemplary embodiments provide a device comprising a unitary toroidal hose retractor for use with a pull-out hose, said hose retractor defining a passage there-through having a passage width greater than an outer width of the pull-out hose, an inner portion of a radial cross-section of said hose retractor defining a conic segment having a focal point and a conic segment radius measured from said focal point.
Claims39
A device comprising:
- a unitary toroidal hose retractor for use with a pull-out hose, said hose retractor defining a passage there-through having a passage width greater than an outer width of the pull-out hose, an inner portion of a radial cross-section of said hose retractor defining a conic segment having a focal point and a conic segment radius measured from said focal point, wherein a static coefficient of friction between a surface of said inner portion of the radial cross-section of said hose retractor and a surface of the pull-out hose is less than about 0.20.
A system comprising:
- a pull-out hose;
- and
- a unitary toroidal hose retractor for use with said pull-out hose, said hose retractor defining a passage there-through having a passage width greater than an outer width of said pull-out hose, an inner portion of a radial cross-section of said hose retractor defining a conic segment.
A method of providing a pull-out hose and a hose retraction device comprising the activities of:
- providing a pull-out hose;
- and
- providing a unitary toroidal hose retractor for use with the pull-out hose, the hose retractor defining a passage there-through having a passage width greater than an outer width of the pull-out hose, an inner portion of a radial cross-section of the hose retractor defining a conic segment.
A method of retracting a pull-out hose comprising the activities of:
- inserting a pull-out hose through a passage defined by a unitary toroidal hose retractor for use with the pull-out hose, defining a passage there-through having a passage width greater than an outer width of the pull-out hose, an inner portion of a radial cross-section of the hose retractor defining a conic segment;
- attaching a first terminal end of the pull-out hose to a fluid flow regulation device;
- attaching a second terminal end of the pull-out hose to a fixed fluid dispensing device;
- positioning the pull-out hose in a manner that allows the hose retractor to freely slide to a position between the first terminal end of the pull-out hose and the second fixed terminal end of the pull-out hose.
