US Patent 7171723 Floor suction tool for electric vacuum cleaners

A floor suction tool for electric vacuum cleaners includes a suction opening formed on a bottom face of a main body casing, a cover defining a front wall of the main body casing, and an abutting member projecting from a front face of the cover and functioning as a bumper between a front face of the main body casing and a wall. The cover is rotatably supported on a rotation axis formed horizontally in a direction of width of the front wall of the main body casing, the cover rotates upward to open the front face of the main body casing when a front-to-back force acts on the abutting member, and the cover rotates downward to close the front face of the main body casing when the front-to-back force ceases.
