Abstract: An armrest assembly is provided for adjusting an armrest of a seating unit in three degrees of motion. The armrest assembly includes an angle-adjustment mechanism that allows the armrest to pivot and to translate forward, and a lift mechanism that enables vertical articulation of the armrest. The angle-adjustment assembly includes a pivot bracket with a downwardly disposed pin and a shuttle with an arcuate slot to receive the pin. The arcuate slot includes contoured walls that form detents for restricting movement of the pin, thereby restraining rotation of the shuttle, with respect to the pivot bracket, to predefined angular positions. The lift mechanism includes a rack with ride element(s) extending therefrom and locking teeth, and a control bar with track(s). An upward manual actuation of the control bar causes the track to shift laterally and retract the locking teeth, via interaction between the track(s) and ride element(s), respectively.

Abstract: A floor sweeper for recovering material from a surface to be cleaned comprises a handle assembly pivotably attached to a foot assembly. The foot assembly comprises a housing forming a brush chamber having a bottom opening. The foot assembly comprises a pair of driving gears and a split brush assembly rotatably mounted within the brush chamber and adapted to contact the surface through the opening. The brush assembly comprises two separately-rotatable halves each corresponding to one of the driving gears, with each half comprising a brush core, brush paddles or bristles affixed to an exterior of the brush core, and a brush gear adapted for rotation with the brush core. Each brush gear is driven by a corresponding driving gear to the corresponding brush core as the floor assembly is moved across the surface in order to drive the brushes to cleaning of the surface.
