Publication number: 20110305864Abstract: A fastening member according to the invention includes right and left sewn areas which are sewn to one member out of a cushion member and a cover material, a hook-and-loop fastener area which is disposed between the right and left sewn areas and which has a plurality of female engagement elements formed on one face thereof, and a connection area which connects between the hook-and-loop fastener area and the respective sewn areas. Here, the connection area is configured to have a lower yarn density than that of the sewn areas and allows the hook-and-loop fastener area to be displaced relatively to the sewn areas. According to the fastening member of the invention, since the fastened cover material can be easily displaced against the cushion member, wrinkling occurrence at the cover material can be prevented when the cover material is assembled to the cushion member.Type: ApplicationFiled: April 30, 2009Publication date: December 15, 2011Applicant: YKK CorporationInventors: Yuichi Masuda, Ryuichi Murasaki

Patent number: 7493676Abstract: Hook structures for use in hook and loop or hook and engagement material fastening applications. Structures according to embodiments of the invention include hooks which extend from bases which in turn extend from a foundation and also extend laterally across the structures. The bases are separated by valleys which also extend laterally across the structures, whose height can be uniform laterally in the structures or varied. The bases provide suitable strength and support to allow the hooks to be robust and strong for permanent or semi-permanent fastening applications, while the valleys interposed between bases allow the hooks to penetrate sufficiently deeply into the engagement material for effective fastening to occur. Such structures may be formed according to processes which physically or conceptually employ various layers to support hooks, retention barrier members such as fingers interposed laterally between hooks, and/or for spacing such hooks and barriers as desired.Type: GrantFiled: April 13, 2006Date of Patent: February 24, 2009Assignee: YKK CorporationInventors: Ryuichi Murasaki, Tsuyoshi Minato

Patent number: 7022394Abstract: The present invention provides a fastener strip having magnetically attractable particles which are not located across the entire volume of the strip, but rather are incorporated in a discrete, distinct area of the strip. The fastener strip has a base and many hook pieces which rise from a fastening surface of the base. One embodiment has a magnetically attractable body in a row which rises from the surface of the base and is located along a substantially center line of the fastener strip. The magnetically attractable particles are incorporated in the magnetically attractable body and a part of the base located below the magnetically attractable body, and the magnetically attractable particles are not dispersed across the whole area of the base. A method of manufacturing such a strip is also described here.Type: GrantFiled: October 5, 2001Date of Patent: April 4, 2006Assignee: YKK CorporationInventors: Nobuo Fujisawa, Craig Jay Graham, Tsuyoshi Minato, Ryuichi Murasaki, Mitsuru Akeno

Patent number: 6720059Abstract: This invention provides a fastener strip in which fastening elements form a fastener layer on a front face of the fastener strip. Rows of vertical members are disposed along each of the side edges of the fastener layer and each row comprises vertical members formed with an appropriate interval between them for controlling the degree of foam penetration during the molding process. The vertical members anchor the fastener strip to an object during molding of the object and form an effective seal against fouling of the fastening elements.Type: GrantFiled: October 5, 2001Date of Patent: April 13, 2004Assignee: YKK CorporationInventors: Nobuo Fujisawa, Craig Jay Graham, Tsuyoshi Minato, Ryuichi Murasaki, Mitsuru Akeno

Patent number: 6659851Abstract: A fastening device for a polishing paper cloth of a portable polishing machine. The device comprises an attaching portion which can be detachably attached to a base plate of the polishing machine and a fastening device main body for winding the polishing paper cloth thereon to engage therewith. Multiple concave grooves, which are continuous in the winding direction of the polishing paper cloth in parallel, and a cavity portion formed inside are provided. Therefore, by giving flexibility to the main body to allow it to be deformed in many directions, it is possible to prevent a reaction to the operator due to oscillation of the polishing machine generated during the polishing and to improve a discharging function for the polishing waste to the outside by allowing the polishing waste generated during the polishing to easily intrude in the concave grooves.Type: GrantFiled: April 12, 2002Date of Patent: December 9, 2003Assignee: YKK CorporationInventors: Yoshinobu Takahashi, Toshiaki Takizawa, Ryuichi Murasaki

Patent number: 6647750Abstract: In a buckle, in which a housing of a female body and an inserting plate of a male body are engaged with each other and which is provided with a simple locking mechanism by using a key, the housing of the female body is provided with an engaging portion, while the inserting plate of the male body is provided with an engaged portion. Alternatively, the housing is provided with an engaged portion while the inserting plate is provided with an engaging portion. Therefore, the female body and the male body can be engaged with each other to be locked. When they are locked, a belt adjusting portion of the male body is concealed in the housing of the female body, so that a belt is difficult to be adjusted. Specifically, the belt can be never loosened but only adjustable in a direction of fastening. Thus, the buckle is provided with a convenient belt adjusting portion, which can not adjust a length of the belt when the female body and the male body are locked with each other.Type: GrantFiled: July 16, 2001Date of Patent: November 18, 2003Assignee: YKK CorporationInventors: Hitoshi Kaneko, Ryuichi Murasaki, Yoshinobu Takahashi

Patent number: 6610231Abstract: The molding method for molded surface fastener for molding a flat substrate and a plurality of first engaging elements integrally and continously using the same molding material. According to the method, a cooling/transportation means for cooling and transporting a molded surface fastener at the same time when it is molded is driven and rotated in one direction and molten resin material is extruded continuously onto a cooling/transportation face through a resin extrusion path which extends in a width direction of an extrusion nozzle and which is open to said cooling/transportation face of said cooling/transportation means and opens in a transportation direction thereof. At this time, a plurality of the first engaging-element-molding openings spaced in the width direction of said resin extrusion path are opened and closed by means of at least a vertically vibrating member disposed on a front face of said extrusion nozzle in a resin transportation direction thereof.Type: GrantFiled: September 24, 2001Date of Patent: August 26, 2003Assignee: YKK CorporationInventors: Toshiaki Takizawa, Ryuichi Murasaki
