Publication number: 20170057714Abstract: A cable tie may include a belt and a buckle to which a proximal end of the belt is connected. When the belt wrapped around a clamped article is inserted into an insertion hole of the buckle through an inlet end and is then tightened, the belt can be locked to the buckle while the belt is fastened around the clamped article. After the belt is locked to the buckle, an excess portion of the belt drawn from an outlet end of the insertion hole of the buckle is cut off while leaving a remaining portion. The buckle has a protecting portion that is configured to cover both sides of the remaining portion of the belt. The protecting portion is configured to cover all of four corners of a cut surface of the remaining portion of the belt.Type: ApplicationFiled: August 18, 2016Publication date: March 2, 2017Inventors: Haruhisa KAMIYA, Toshio IWAHARA, Makoto KATO, Katsuya HIRAKAWA

Patent number: 9488202Abstract: A clip having a main clip body that is made of resin and has a shape in front view that is closed at one end and open at the other end. The main clip body has engaging arms and holding members positioned to the inside of the engaging arms. The engaging arms are configured so as to be elastically deformed when the main clip body passes through an installing hole of a partner panel and to engage with a rim of the hole when the engaging arms have been inserted. The holding members are configured so as to keep the main clip body fitted onto the clip seat of the mounted member. The engaging arms and the holding members are connected to assume a substantially diamond-shaped loop in front view, and are configured so that the positions thereof differ in side view, and overlap in front view, when elastically deformed.Type: GrantFiled: August 8, 2012Date of Patent: November 8, 2016Assignee: DAIWA KASEI KOGYO KABUSHIKI KAISHAInventors: Jun Komeno, Takahiro Sugiyama, Toshio Iwahara

Patent number: 9284974Abstract: In a clip that copes with pitches of a plurality of types of screw grooves, force to support the engaged screw members is increased at low cost. The clip includes opposite elastic locking pieces. Each elastic locking piece extends from a first side to a second side opposite to the first side, in the direction of the axis of the screw member such that its leading end approaches the screw member within the insertion hole of a tubular body part. Each elastic locking piece is elastically deformable such that its leading end is separated from the screw member. Each locking piece has at its leading end a locking claw that engages with the screw groove of the screw member. The first side of the locking claw has a straight section extending straight, and the second side opposite to the first side has a helical section extending helically along the groove.Type: GrantFiled: April 23, 2014Date of Patent: March 15, 2016Assignee: DAIWA KASEI INDUSTRY CO., LTD.Inventors: Toshio Iwahara, Makoto Kato, Atsutoshi Kaji

Publication number: 20150337882Abstract: A clip attachment structure with a clip and a mounting member attached to a panel by the clip is provided. The clip has an anchor that attaches the mounting member to the panel by insertion into a clip hole in the panel. A pair of elastic claws extends from the anchor. The pair of elastic claws may engage with the clip hole and may disengage from the clip hole upon rotation of the clip relative to the clip hole from an attached position. The mounting member has a pair of ribs configured to guide the clip relative to the mounting member to orient the pair of elastic claws to engage with the edges of the clip hole.Type: ApplicationFiled: January 15, 2014Publication date: November 26, 2015Inventors: Toshio IWAHARA, Makoto KATO, Tetsuya OGINO

Publication number: 20150113773Abstract: Embodiments of the present invention may include a clip mounting seat having a clip attachment surface, a peripheral wall and an opening. The peripheral wall extends from the clip attachment surface. The opening opens a part of an outer peripheral edge of the clip attachment surface. The clip attachment surface has an attachment hole, a guide groove and a tongue. The guide groove guides an insertion of a neck portion of the clip from the opening into the attachment hole. The tongue protrudes from an edge of the guide groove towards the attachment hole. The tongue is deflected to permit the neck portion to enter from the opening into the attachment hole. When the neck portion moves from the attachment hole toward the opening, the tongue is deflected by the neck portion in a closing direction.Type: ApplicationFiled: October 29, 2014Publication date: April 30, 2015Inventors: Toshio IWAHARA, Makoto KATO, Junya UKAI, Kazuki FUJII
