Publication number: 20140151514Abstract: A corrugated tube clamp may includes a fixed portion capable of being connected to an attaching object, a movable portion hinged to the fixed portion, ribs respectively formed in the fixed portion and the movable portion, and at least one biasing member formed in at least one of the fixed portion and the movable portion. The fixed portion and the movable portion are shaped to clamp and hold each of corrugated tubes having different diameters therebetween. The ribs are respectively shaped to engage grooves formed in an outer circumferential surface of each of the corrugated tubes of different diameters. The at least one biasing member is shaped to be pressed back by an outer circumferential surface of at least the corrugated tube with the smallest diameter when it is clamped between the fixed portion and the movable portion.Type: ApplicationFiled: November 27, 2013Publication date: June 5, 2014Applicant: DAIWA KASEI KOGYO KABUSHIKI KAISHAInventor: Osamu ASAI

Patent number: 8695177Abstract: A clip may include a main body and a pin member. In the clip, an engagement condition of the anchor to an attaching hole formed in a plate member can be maintained by inserting an elastic shank portion of the pin member into the anchor of the main body. The elastic shank portion inserted into the anchor is received by a stopper of the anchor, so that the pin member can be locked in a temporary insertion position. An interfering portion of the elastic shank portion is exposed to an exterior portion the anchor. When the anchor is inserted into the attaching hole, the interfering portion of the elastic shank portion interferes with a periphery of the attaching hole, so that a condition in which the pin member is locked in the temporary insertion position can be released.Type: GrantFiled: January 28, 2011Date of Patent: April 15, 2014Assignee: Daiwa Kasei Kogyo Kabushiki KaishaInventors: Makoto Kato, Haruhisa Kamiya, Toshio Iwahara, Hideyuki Kawaguchi
