Patent number: 5778734Abstract: An upper cover (12) and a lower cover (14) are fastened to each other on their front faces by a hexagon socket head cap screw (40). While a cover supporting column (34) is received on a column seat (38) of each fixation tongue (30) projected from the upper cover (12), the end face of the cover supporting column (34) is brought into contact with a column contact surface (36) of the fixation tongue (30). The hexagon socket head cap screw (40) is inserted through a spot facing slot (60) and a through slot (58) of the lower cover (14) and a through hole (48) of the upper cover (12) and eventually screwed into a tapped hole (42) of the cover supporting column (34). The cover supporting column (34) and the fixation tongue (30) of the upper cover (12) are positioned and fixed to each other via the hexagon socket head cap screw (40), which goes through the positioning through hole (48) of the fixation tongue (30) and is screwed into the tapped hole (42).Type: GrantFiled: March 4, 1996Date of Patent: July 14, 1998Assignee: Toyota Jidosha Kabushiki KaishaInventor: Terumune Uchida

Patent number: 5687529Abstract: A fastening device (10) for securing panels (252) to each other, foundations (258) and other surfaces is disclosed including cam elements (50) which are rotated to fasten with locking plates (29). Specifically, elongated hollow channels (11) are provided of an identical construction including slots (24) formed in the free edges of lips (21, 23) defining a slit opening (19). Grooves (22) are formed in the abutting, outside surfaces of the lips (21, 23) for receipt of seals (214). The heads (216) of the seals (214) in an uncompressed condition are of a height substantially greater than and of a width substantially less than the depth and width of a trough (208) of the groove (22) and are compressible to fit completely within the trough (208). The cam elements (50) are rotatably mounted between the support walls (202) of a U-shaped carrier (200). The upper ends of the support walls (202) integrally terminate in shelves (206) having edges which are slideably mounted in the slots (24) of the channels (11).Type: GrantFiled: June 7, 1996Date of Patent: November 18, 1997Assignee: WorldTec Systems, Inc.Inventor: Richard Pickering

Patent number: 5651631Abstract: A tool handle assembly includes a molded adapter bonded to the end of a handle shaft, which adapter includes a generally cylindrical cap portion and a generally tapered frustoconical portion that surrounds the handle shaft adjacent to the cap portion. The handle assembly is inserted into a lower entrance of a tapered eyehole of a tool head such that the frustoconical portion of the adapter engages a portion of the eyehole. In one preferred form, the cap portion of the adapter includes external barbs. A pair of arcuate wedges having interior teeth are inserted between the cap portion of the adapter and the tool head and bear on the major axis of the tool head. The teeth of the wedge cooperate with the barbs of the adapter to secure the wedges in place. In another preferred form, the adapter includes a pair of slots into which wedge inserts are driven to expand the cap portion of the adapter and thus secure the tool head to the handle assembly.Type: GrantFiled: July 10, 1996Date of Patent: July 29, 1997Inventor: Joseph Allen Carmien
