Abstract

Ladders, ladder components and related methods are provided including various embodiments of a combination ladder. In some embodiments, a platform is provided that is fixedly coupled with a rail assembly of a combination ladder. The platform may pivot between a useable position or state and a stowed or stored position or state. The platform may maintain a position relative to certain rungs of the rail assembly while being displaceable relative to other rungs of the rail assembly. A hand rail may be coupled to the rail assembly and a tray may be coupled with the hand rail. The tray and the platform may be configured to maintain a constant distance between one another while the rail assembly is adjusted for height.

Claims (10)

1. A ladder comprising:

at least one rail assembly including a pair of rails and at least one rung coupled between the pair of rails;

a first foot removably coupled with an end of an associated rail of the pair of rails, the foot including a body portion configured to cover an end of the associated rail, the body portion including a first wall having a flexible locking tab formed therein and extending in the same plane as the first wall, the locking tab having a feature formed at a free end of the locking tab including a protrusion that extends into a through hole formed in the associated rail, wherein a surface of the flexible locking tab is exposed to a user on a first side of the associated rail and wherein the protrusion extends through the through hole and is exposed on second side of the associated rail.

2. The ladder of claim 1 , wherein the feature formed in the free end of the locking tab is selectively displaceable from the through hole, and wherein the body portion of the foot further defines at least one channel to receive a portion of the associated rail, the body being configured to slide along a length of the associated rail when the feature formed in the free end of the lacking tab is disengaged from the through hole.

3. The ladder of claim 1 , further comprising a wheel rotatably coupled with body portion of the first foot.

4. The ladder of claim 3 , wherein, when the ladder is placed on a supporting surface in an intended operating orientation, the wheel does not contact the supporting surface.

5. The ladder of claim 1 , further comprising a second foot coupled with an end of the other rail of the pair of rails, the second foot including a body portion configured to cover an end of the other ladder rail, the body portion including a first wall having a flexible locking tab formed therein and extending in the same plane as the first wall, and a feature formed at a free end of the locking tab extending into a through hole formed in the other rail.

6. The ladder of claim 1 , wherein the protrusion is formed adjacent the free end of the locking tab.

7. The ladder of claim 1 , wherein the foot comprises plastic.

8. The ladder of claim 1 , wherein the body, including the first wall and its locking tab, is a molded structure.
