Abstract:
A wire-winding device for reversibly actuating the reconfiguration of an umbrella between open and closed configurations comprising:(a) a casing having an opening formed therethrough, said casing having formed therein a bore opposing said opening, said bore being defined by a base surface portion and a sidewall surface portion of predetermined length extending axially therefrom;(b) a nut member disposed in axially displaceable manner within said bore of said casing;(c) a crank arm coupled to said casing, said crank arm including an axle portion extending axially into said opening of said casing in angularly displaceable manner; and,(d) a reel shaft extending coaxially from said crank arm axle portion for angular displacement therewith, said reel shaft having an end portion threadedly engaging said nut member, said nut member being thereby axially displaceable toward said base surface portion of said casing bore responsive to angular displacement of said reel shaft in a predetermined angular direction, said nut member being limited in axial displacement by said casing bore base surface portion;whereby an actuation wire of the umbrella may be selectively wound and unwound about said reel shaft to reconfigure the umbrella between the open and closed configurations thereof.
