A rib, formed on the upper section of the rotating brush holding chamber, extends along the length of the rotating brush, near the rotation path of the rotating brush. An air current path is formed to take dust drawn up by the rotating brush and stopped by the rib and suck it into the suction opening leading to the main cleaning device unit. The air current path is shaped so that its cross section is smaller at an end of the air current path remote from the suction opening than it is near the suction opening to increase flow speed at the remote end.Type: GrantFiled: March 29, 2000Date of Patent: April 1, 2003Assignee: Sanyo Electric Co., Ltd.Inventors: Atsushi Okuda, Atuo Hamada, Souji Sakata, Kazuyoshi Yoshimi, Kazumasa Kamatani, Nobuaki Takahashi, Syuzo Ueyama, Naoki Suetugu

Patent number: 6539582Abstract: A hinge device including: a bracket having a shaft hole; a shaft inserted through the shaft hole; a longitudinal insert home diametrically formed on one or both sides of the shaft and a pair of shoulder members formed centrally on the shaft with a fixed distance from one another. A first shoulder member is larger than the second shoulder member. A torsion spring is placed between the bracket and the shaft. A plurality of space washers having holes placed on one or both sides of the bracket. A plurality of disc springs have through holes which have protrusion members that insert into the insert home of the shaft when the shaft is inserted into the bracket. A guide washer having a through hole which has protrusion member that inserts into the insert home of the shaft when the shaft is inserted into the bracket. A nut screw onto the shaft to stabilize a horizontal position of the attached elements.Type: GrantFiled: July 12, 2001Date of Patent: April 1, 2003Assignee: P.K.

Patent number: 6539583Abstract: In a frictional hinge device, a metallic shaft has a rotational axis as a rotational center. A support block is made of a synthetic resin so that the support block rotatably supports the metallic shaft relatively. The support block is relatively rotatable in relation with the metallic shaft by a surface friction resistance between the support block and the metallic shaft. A surface treatment imparts Vickers number (Hv) of 800 or more with an outer surface of the metallic shaft. As an alternative, a hardened layer is provided around the outer surface of the metallic shaft and the hardened layer has Vickers number (Hv) of 800 or more with its thickness at least in 5.0 &mgr;m.Type: GrantFiled: May 10, 2000Date of Patent: April 1, 2003Assignee: Chuo Hatsujo Kabushiki KaishaInventors: Masato Uneme, Takaaki Hayashida

Patent number: 6539584Abstract: A self-locking hinge is comprised of a housing with spaced side walls, and a cogged wheel positioned between the side walls. A pair of slots are respectively positioned on the interior surfaces of the side walls. A stop is connected between the side walls in alignment with the slots. An axle positioned through a center of the cogged wheel has opposite ends positioned in the slots. The cogged wheel is secured in position when it is biased against the stop by springs positioned in the slots and engaged against the ends of the axle. The cogged wheel is pivotable when it is pushed away from the stop against the springs, and is automatically biased against the stop and secured in position when it is released.Type: GrantFiled: November 1, 2001Date of Patent: April 1, 2003Inventor: Michael Gillotti
