Abstract
A ladder includes a foot having a plastic body with a recess which receives the end of a first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The foot has a metal rail fastener which extends through the body and the rail to attach the body and the rail together. The foot has a pad and a metal pad fastener that extends entirely through the pad and entirely through the base to attach the pad to the base.
Claims18
A ladder foot comprising:
- a foot body comprising a base with a first planar surface, a first flange extending upwardly from the first planar surface of the base adjacent a first end of the first planar surface, a second flange extending upwardly from the first planar surface of the base adjacent a second end of the first planar surface substantially parallel to the first flange, and a first web portion extending upwardly from the first planar surface between the first flange and the second flange, wherein the base, the first flange, the first web portion, and the second flange define a single integral component such that the first flange and the second flange are fixed with respect to the first planar surface of the base;
- and
- a shield coupled around the foot body to form a c-shaped recess between the shield and the first web portion, the first flange, and the second flange, the c-shaped recess shaped to receive a bottom region of a rail of a ladder to sandwich the bottom region of the rail between the shield and the foot body,
- wherein the shield is defined in part by a first c-shaped wall comprising a second web portion, a third flange extending from a first end of the second web portion and a fourth flange extending from a second end of the second web portion, and wherein the first flange, the second flange, and the first web portion of the foot body define a second c-shaped wall of the foot body, wherein the second c-shaped wall of the foot body and the first c-shaped wall of the shield are nested such that the first flange and the second flange extend from the first web portion in a first direction and the third flange and the fourth flange extend from the second web portion in the first direction, and the c-shaped recess is defined between the first c-shaped wall and the second c-shaped wall and corresponds to a c-shaped cross-section of the bottom region of the rail.
A ladder comprising:
- a first rail having a bottom region that extends a partial distance along the first rail from a distal end thereof;
- a second rail;
- rungs attached to the first rail and second rail;
- a foot body having a base, the base having a first planar surface and a first flange extending upwardly from the first planar surface of the base adjacent a first end of the first planar surface and a second flange extending upwardly from the first planar surface of the base adjacent a second end of the first planar surface substantially parallel to the first flange, wherein the base, the first planar surface, the first flange, and the second flange define a single integral component such that the first flange and the second flange are fixed with respect to the first planar surface of the base;
- a shield coupled to the foot body around the bottom region to sandwich the bottom region between the shield and the first and second flanges, the shield having a bottom that in its entirety overlays the first planar surface;
- a pad coupled to an underside of the base, the pad having an uppermost planar surface coupled flush with a lowermost planar surface of the base when the pad is secured to the base, and wherein the pad includes a plate and an outer layer completely surrounding the plate, the outer layer including the uppermost planar surface;
- and
- a pad fastener that extends entirely through the pad by way of one of a plurality of holes in the plate and entirely through the base to attach the pad to the base.
A ladder comprising:
- a first rail having a bottom region that extends a partial distance along the first rail from a distal end thereof;
- a second rail;
- rungs attached to the first rail and second rail;
- a foot body having a base, the base having a first planar surface and a first flange extending upwardly from the first planar surface of the base adjacent a first end of the first planar surface and a second flange extending upwardly from the first planar surface of the base adjacent a second end of the first planar surface substantially parallel to the first flange, and a first web portion extending upwardly from the first planar surface between the first flange and the second flange, wherein the base, the first flange, the first web portion, and the second flange define a single integral component such that the first flange and the second flange are fixed with respect to the first planar surface of the base;
- and
- a shield coupled to the foot body to form a c-shaped recess between the shield and the first web portion, the first flange, and the second flange of the foot body, the c-shaped recess shaped to receive the bottom region to sandwich the bottom region between the shield and the foot body,
- wherein the shield is defined in part by a first c-shaped wall comprising a second web portion, a second flange extending from a first end of the second web portion, and a third flange extending from a second end of the second web portion, and the first flange, the second flange, and the first web portion define a second c-shaped wall of the foot body, and the c-shaped recess is defined between the first c-shaped wall and the second c-shaped wall and corresponds to a c-shaped cross-section of the bottom region of the first rail,
- wherein the first web portion of the foot body has an inner surface facing an interior of the ladder and an opposing outer surface, and the first rail, the c-shaped recess, and the second web portion are disposed outwardly from the outer surface.
