Abstract
An adjustable curvature cleaning structure adapted to clean both flat and curved surfaces. The cleaning structure includes a frame having a base operatively engaging an elongated handle structure and at least one arm projecting away from the base. The arm includes multiple link elements with hinges disposed between the link elements such that the arms are bendable in curved relation to adjust elevation relative to the base. At least one adjustable length cable extends along the arm and is operatively connected to a length adjustment mechanism.
Claims9
An adjustable curvature cleaning structure adapted to clean both flat and curved surfaces, the cleaning structure comprising:
- a frame comprising a base operatively engaging an elongated handle structure and at least one arm projecting away from the base, said at least one arm comprising a plurality of link elements of polymer or metal with hinges disposed between said link elements such that said at least one arm is bendable upwardly and downwardly in curved relation relative to said base;
- at least one adjustable length cable extending along said at least one arm, wherein at least a portion of said hinges are polymer living hinges and wherein said living hinges comprise segments of polymer ribbons extending in the major length dimension of said at least one arm.
An adjustable curvature cleaning structure adapted to clean both flat and curved surfaces, the cleaning structure comprising:
- a frame comprising a base operatively engaging an elongated handle structure and at least one arm projecting away from the base, said at least one arm comprising a plurality of link elements of polymer or metal with hinges disposed between said link elements such that said at least one arm is bendable upwardly and downwardly in curved relation relative to said base;
- at least one adjustable length cable extending along said at least one arm and further comprising a length adjustment mechanism, wherein the length adjustment mechanism comprises a worm gear operatively connected to a rotatably adjustable spool adapted to take up and release portions of said at least one adjustable length cable in response to adjustment of said worm gear.
An adjustable curvature cleaning structure adapted to clean both flat and curved surfaces, the cleaning structure comprising:
- a frame comprising a base operatively engaging an elongated handle structure and a pair of arms projecting laterally away from opposing sides of the base, the arms comprising a plurality of link elements of polymer or metal with living hinges disposed between said link elements such that said arms are bendable upwardly and downwardly in curved relation relative to said base;
- adjustable length cables extending along said arms, wherein proximal ends of said cables are operatively connected to a length adjustment mechanism disposed at said base, wherein the length adjustment mechanism comprises a worm gear operatively connected to a ring gear surrounding a rotatably adjustable spool engaging said cables and adapted to take up and release portions of said adjustable length cables in response to adjustment of said worm gear.
