Patent number: 8806722Abstract: A clip may include an anchor portion that is configured to be inserted into an insertion hole formed in a subject member. The anchor portion has at least a pair of pillars that are positioned across an axis of the anchor portion, and flexible strips that are respectively connected to the pillars so as to be projected outward therefrom. The pillars are configured to be flexed about proximal ends thereof in a direction in which the pillars can intersect with each other. The flexible strips are configured to engage a periphery of the insertion hole formed in the subject member when the anchor portion is inserted into the insertion hole, so as to hold the anchor portion on the subject member with a retention force. The pillars can be applied with a flexing force when an extraction force greater than the retention force of the anchor portion is applied to the anchor portion, so as to be flexed in the direction in which the pillars can intersect with each other.Type: GrantFiled: November 22, 2011Date of Patent: August 19, 2014Assignee: Daiwa Kasei Kogyo Kabushiki KaishaInventors: Toshio Iwahara, Junya Ukai

Publication number: 20140196261Abstract: A cushion clip may include an engagement leg that is capable of being attached to either one of a fixed member or a movable member moving toward and away from the fixed member; and a cushion that is capable of being elastically deformed by a load applied from the movable member moving toward the fixed member, thereby absorbing impact caused by movement of the movable member. The cushion has a hollow barrel shape such that an intermediate portion positioned between a bottom portion connected to the engagement leg and a top portion positioned opposite to the bottom portion is circumferentially expanded to a maximum circumference.Type: ApplicationFiled: January 10, 2014Publication date: July 17, 2014Applicant: DAIWA KASEI KOGYO KABUSHIKI KAISHAInventors: Haruhisa KAMIYA, Toshio IWAHARA, Keiji OKAICHI, Takeo HORIUCHI

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

Patent number: 8572806Abstract: A grommet configured to seal an insertion hole formed in a panel into which a pipe is inserted may include a base that is configured to be connected to the insertion hole, a boot that is integrally formed in the base and has a thinned wall thickness, and at least one rib that is formed in the boot. The boot has a truncated cone-shaped main portion having an insertion bore into which the pipe can be inserted, and a connecting portion that is folded back from a circumferential periphery of the main portion via a folded back portion and is connected to the base. The at least one rib is formed in the main portion and the connecting portion while straddling the folded back portion, so as to restrict the main portion from being axially displaced relative to the base.Type: GrantFiled: May 25, 2012Date of Patent: November 5, 2013Assignee: Daiwa Kasei Kabushiki KaishaInventors: Toshio Iwahara, Takahiro Sugiyama, Keiji Okaichi, Hayato Kamigashima

Patent number: 8555469Abstract: A clip may include an anchor portion having a plurality of flexible strips and at least one support strip. Each of the flexible strips is integrally connected to the at least one support strip only via a connecting portion corresponding to a distal end portion of the anchor portion and a connecting portion corresponding to a proximal end portion of the anchor portion. When the anchor portion is pushed into an insertion hole formed in a subject member, the anchor portion is inserted into the insertion hole while each of the flexible strips are flexed toward a longitudinal axis of the anchor portion. Each of the flexible strips is formed such that the difference between a second moment of area of the anchor distal end side connecting portion and a second moment of area of the anchor proximal end side connecting portion is 0-15%.Type: GrantFiled: September 29, 2010Date of Patent: October 15, 2013Assignee: Daiwa Kasei Kogyo Kabushiki KaishaInventors: Toshio Iwahara, Kazuki Fujii
