Patent number: 8033582Abstract: A side rock device attaches a first member to a second member to be openable. The side rock device includes a pair of lock arms, a housing which holds the lock arms movably, a slider defining inclining holes which engage with the lock arms and urge the lock arms to protrude and retract, the slider disposed in the housing, and an elastic member which elastically urges the slider toward a predetermined direction. When the slider is operated against an elastic urging force of the elastic member, the lock arms are retracted.Type: GrantFiled: May 29, 2003Date of Patent: October 11, 2011Assignee: Piolax, Inc.Inventors: Seiji Sawatani, Hiroaki Ichioka

Patent number: 7243401Abstract: A clip includes an insertion member whose cross-sectional shape is in a T-shape, having a head portion and a shaft portion connected downwardly from the head portion; a latch member in a V-shape disposed on an outer side of the shaft portion; and a hinge member connecting the shaft portion and the latch member. Split flanges, mated in a flange-shape by surrounding the shaft portion when both side leg portions are closed, are provided to be continued from upper end portions of the both side leg portions. One side of an abutting surface of each split flange protrudes to form an L-shape in a plan view and abuts against a corresponding side portion of the shaft portion. A retaining protruding piece extending from a side portion opposite to a protruding portion and engaging with corresponding side portion of the shaft portion is formed on each both side leg portions.Type: GrantFiled: March 18, 2004Date of Patent: July 17, 2007Assignee: Piolax, Inc.Inventor: Seiji Sawatani

Patent number: 6598925Abstract: A fixing structure is constituted by a housing (1) fixed to a mounting hole H on the side of a vehicle member, and a storage member 2 supported in the housing (1) so that the storage member (2) can be opened and closed. A frame member 3 made of resin material having greater toughness than the housing (1) is mounted to an outer periphery of the housing (1). The frame member (3) is integrally provided with resilient leg pieces (4A), (4B) and (4C) which are retained to hole edges of the mounting hole (H). With this, the resilient leg pieces (4A), (4B) and (4C) to be retained to the hole edges of the mounting hole (H) on the side of the vehicle member are not provided on the housing (1), but are integrally provided on the frame member (3) made of resin material having greater toughness than the housing (1).Type: GrantFiled: June 26, 2002Date of Patent: July 29, 2003Assignee: Piolax Inc.Inventors: Seiji Sawatani, Toshiko Watanabe, Toshihiko Ookawara

Patent number: 6367785Abstract: A tubular cylinder has a first end and a second end. A piston is movable in the cylinder. A compressed coil spring resiliently biases the piston toward the first end of the cylinder. A string transmits a damper function, caused by a movement of the piston, to a body to be moved. The string slideably wraps over the piston, and extends the length of the cylinder.Type: GrantFiled: October 6, 2000Date of Patent: April 9, 2002Assignee: Piolax, Inc.Inventors: Isao Nakabayashi, Seiji Sawatani

Patent number: 5263346Abstract: A locking device for a lid on a box includes a frame adapted to be fixed on the side of the lid and provided with a cylinder lock having an eccentric shaft and a cylindrical retaining part for retaining the cylinder lock therein. An opening-shutting knob is pivotally supported on the frame and has a depressing claw part, and a locking member is provided on the side of the frame for locking a striker disposed on the side of the box. An operating lever has one end portion thereof connected to the eccentric shaft of the cylinder lock and the other end portion thereof serving to release a locked state of the locking member by interfering with the depressed claw part of the opening-shutting knob during unlocking of the locking device. The operating lever is formed of a synthetic resin material and has an elastic engaging piece integrally formed to the one end portion. The elastic engaging piece has a projecting part formed thereon.Type: GrantFiled: September 28, 1992Date of Patent: November 23, 1993Assignee: Kato Hatsujo Kaisha, Ltd.Inventors: Seiichi Sato, Seiji Sawatani
