Claims7
A sewing head navigator, comprising:
- a) a navigator body disposed between a pair of hand grippable ends, said navigator body having a top side and a bottom side defining a perimeter edge, said bottom side configured to slidely engage a stitchable material;
- and
- b) a pivot element coupled to said navigator body at a location between said pair of grippable ends, said pivot element comprising an aperture element and a slot element extending inwardly from said perimeter edge to communicate with said aperture element, said slot element configured to allow location of a hopping foot in said aperture element, said aperture element configured to pivotally couple to an external surface of said hopping foot of a stitching device to allow coupled rotation of said pair of hand grippable ends of said navigator body about said hopping foot.
A method of using a sewing head navigator, comprising:
- a) engaging a pivot element of a navigator body to a hopping foot of a stitching device, said navigator body disposed between a pair of hand grippable ends, said navigator body having a top side and a bottom side defining a perimeter edge, said bottom side configured to slidely engage a stitchable material, said pivot element comprising an aperture element and a slot element extending inwardly from said perimeter edge to communicate with said aperture element, said slot element configured to allow location of a hopping foot in said aperture element, said aperture element configured to pivotally couple to an external surface of a said hopping foot of a stitching device to allow coupled rotation of said pair of hand grippable ends of said navigator body about said hopping foot;
- b) gripping said navigator body by said pair of hand grippable ends;
- c) sufficiently forcibly urging said pair of grippable ends of said navigator body to generate movement in said hopping foot in relation to said stitchable material.
