Abstract
A step stool includes a frame including a front leg and a rear leg coupled to the front leg for movement relative to the front leg, a handle supported for pivotable movement on the front leg about a pivot axis, and a retainer coupled to the handle to move therewith about the pivot axis and arranged to trap a portion of the rear leg between the handle and the retainer upon movement of the handle to a predetermined position relative to the rear leg to lock the front leg to the rear leg.
Claims31
A step stool comprising
- a frame including a front leg and a rear leg coupled to the front leg for movement relative to the front leg,
- a handle supported for pivotable movement on the front leg about a pivot rod, and
- a retainer coupled to the handle to move therewith about the pivot rod and arranged to clampingly trap a portion of the rear leg between the rod and the retainer upon movement of the handle to a predetermined position relative to the rear leg to lock the front leg to the rear leg.
A step stool comprising
- a frame including a front leg and a rear leg coupled to the front leg for movement relative to the front leg,
- a handle,
- a handle mount coupled to the front leg and arranged to support the handle for pivotable movement about a pivot rod,
- a handle anchor coupled to the rear leg and arranged to mate with the handle upon movement of the rear leg to lie alongside the front leg, and
- a retainer coupled to the handle to move therewith about the pivot rod and arranged to clampingly trap a portion of the handle anchor between the rod and the retainer upon movement of the handle about the pivot axis to assume a stool-carrying position when the handle anchor is mated to the handle.
A step stool comprising
- a frame including a front leg and a rear leg coupled to the front leg for movement relative to the front leg, the front leg including a longitudinal leg coupled to the rear leg and adapted for engagement with a foundation,
- a handle coupled to the front leg for pivotable movement about a pivot axis that is parallel to a longitudinal axis of the longitudinal leg, and
- a portion of the handle including locking means for locking the rear leg to the handle when the rear leg is positioned to lie alongside the front leg in response to movement of the handle relative to the front leg to retain the rear leg in a fixed position alongside the front leg.
A step stool comprising a frame including a front leg and a rear leg movable relative to the front leg between an opened, use position and a closed, storage position, the front leg extending longitudinally and coupled to the rear leg, a handle supported for pivotable movement on one of the legs about a pivot axis that is parallel to a longitudinal axis of the front leg and a retainer carried by the handle to move with the handle about the pivot axis to lock the front leg to the rear leg in the collapsed, storage position so that the step stool can be carried using the handle.
