Abstract
A step stool includes a step frame and a handrail movable relative to the step frame between lowered and raised positions. The handrail includes a handle and left and right handle support arms coupled to the handle to allow sliding movement of the handle relative to the left and right handle support arms as the handrail is moved relative to the step frame between raised and lowered positions. A tray is mounted for pivotable movement on a handle located between the left and right handle support arms about a pivot axis established by the handle.
Claims20
A step stool comprising
- a frame including a left leg and a right leg arranged to lie in nonparallel relation to the left leg,
- steps coupled to the frame, and
- a movable handrail including a left handle support arm mounted for movement in upward and downward directions along the left leg, a right handle support arm mounted for movement in upward and downward directions along the right leg, a handle, and means for slidably coupling the handle to the left and right handle support arms to cause a left end of the handle to extend into a left-end opening formed in the left handle support arm and a right end of the handle to extend into a right-end opening formed in the right handle support arm to produce an exposed portion of the handle in a position between the left and right handle support arms and to support the handle for sliding movement relative to at least one of the left and right handle support arms so that an effective length of the exposed portion is maximized upon downward movement of the left and right handle support arms relative to the non-parallel left and right legs of the frame to establish a lowered position of the movable handrail on the frame and is minimized upon upward movement of the left and right handle support arms relative to the left and right legs of the frame to establish a raised position of the movable handrail on the frame.
A step stool comprising
- a frame including a left leg and a right leg arranged to lie in nonparallel relation to the left leg,
- steps coupled to the frame, and
- a movable handrail including a handle having a left end and a right end, a left handle support mounted for movement in upward and downward directions on the left leg and formed to include a handle receiver arranged to receive the left end of the handle for slidable movement therein, and a right handle support mounted for movement in upward and downward directions to the right leg and formed to include a handle receiver arranged to receive the right end of the handle for slidable movement therein.
A step stool comprising
- a frame,
- steps coupled to the frame, and
- a movable handrail including a handle having a left end and a right end, a left handle support arm formed to include a handle receiver arranged to receive the left end of the handle for slidable movement therein, and a right handle support arm formed to include a handle receiver arranged to receive the right end of the handle for slidable movement therein, the left and right handle support arms being oriented to lie in splayed relation to one another and mounted on the frame for downward movement to establish a lowered position relative to the frame and for upward movement to establish a raised position relative to the frame.
