Patent number: 8793847Abstract: A double-layer nylon zipper includes two zipper tapes each having two series of teeth respectively disposed at opposing top and bottom sides of the fabric strip thereof, and a zipper slider coupled between the interlocking series of teeth of the two zipper tapes and having opposing top guard frame wall and bottom guard frame wall, a division wall between the top and bottom guard frame walls, a nose located on the top guard frame wall and a pull tap coupled to the nose. The top guard frame wall and bottom guard frame wall have respective first ends kept in flush and respective second ends in different lengths so that an accommodation space is defined right below the second end of the top guard frame wall outside the second end of the bottom guard frame wall to facilitate smooth interlocking of the interlocking series of teeth.Type: GrantFiled: July 24, 2012Date of Patent: August 5, 2014Inventor: Roger C. Y. Chung

Patent number: 8499422Abstract: A safety device for a piece of luggage includes a first outside zipper (1) and a second inside zipper (2). The two zippers (1, 2) are superposed in the immediate proximity of one another, such that the teeth (1a, 2a) of the zippers (1, 2) touch under the action of external pressure on the outside zipper (1) by a tip (P) or a pointed tool, by keeping the teeth of the outside zipper (1) from dislocating downward under the pressure of the tip or the pointed tool (P).Type: GrantFiled: March 18, 2010Date of Patent: August 6, 2013Assignee: DelseyInventor: Ebbe Jacobsen

Patent number: 8365367Abstract: The slide fastener includes elements, and a slider, the slide fastener including a horizontal functional section and a vertical functional section. The horizontal functional section includes element heads which are meshed with and unmeshed from each other, and horizontal fastener tapes which are opened and closed in a horizontal direction. The vertical functional section and includes upper element legs which are formed by extending the elements upwards and bending the extended upper portions into a hook-like shape, upper holding portions formed by distal ends of the upper element legs, an upper vertical fastener tape which is engageable in the upper holding portions, lower element legs which are formed by extending the elements downwards and bending the extended lower portions into a hook-like shape, lower holding portions formed by distal ends of the lower element legs, and a lower vertical fastener tape which is engageable in the lower holding portions.Type: GrantFiled: January 3, 2012Date of Patent: February 5, 2013Inventor: Masaki Matsumoto

Publication number: 20120042433Abstract: A zipper arrangement is configured to fasten a first fabric portion to a second fabric portion. The zipper arrangement includes a plurality of first zipper elements positioned along the first fabric portion and a plurality of second zipper elements positioned along the second fabric portion. A zipper closure includes a first closure member releasably coupled to a second closure member. The first closure member is positioned on a mid-portion of the first fabric portion and the second closure member is positioned on a mid-portion of the second fabric portion. A first slider is positioned on one side of the zipper closure and a second slider positioned on an opposite side of the zipper closure. When provided on a garment, the zipper arrangement may be used in association with a method for fastening a first garment portion to a second garment portion by moving the sliders in opposing directions.Type: ApplicationFiled: November 16, 2010Publication date: February 23, 2012Applicant: UNDER ARMOUR, INC.Inventors: Jonas K. Damon, Daniel A. Sanchez, Gregory Daniel Louis Germe, Kajsa Cornelia Anna Maria Westman, Jinseok Hwang, Allison S. Conner

Patent number: 6427294Abstract: The present invention intends to provide a waterproof slide fastener in which a synthetic resin film is fused to a fastener tape in order to prevent a perforation phenomenon that the synthetic resin film does not exist locally. A laminated synthetic resin film composed of low melting point resin layer having melting point of, for example, 100° C.-140° C. and high melting point resin layer having melting point of, for example, 150° C.-230° C. is fused to a surface or both surfaces of a pair of the fastener tapes with the low melting point resin layer being in contact with and opposing the fastener tape by heating with pressure. Fastener elements are mounted onto a side edge of the fastener tape and the laminated synthetic resin film is formed so as to protrude outward from the side edge of the fastener tape and a center point of coupling of the fastener elements.Type: GrantFiled: April 11, 2000Date of Patent: August 6, 2002Assignee: YKK CorporationInventors: Masatoshi Shibaike, Masahiro Kusayama, Sakae Aimono

Patent number: 6292986Abstract: An assembly of sliders for zippers for plastic bags and the like and the accumulation of the sliders for use in form, fill and seal machines is disclosed. The sliders are oriented and mechanically or adhesively joined into chains. Mechanical assembly of sliders may be accomplished by snapping sliders together or slideably mounting sliders on a strip. Sliders may be adhesively assembled together by taping, welding, gluing, or melting the sliders. Sliders and chains of sliders are accumulated in cartridges, carriers, coreless rolls, spools or trays which are then connected to form, fill and seal machines for attachment of the sliders to a zipper and attachment of the zipper with a slider to bags.Type: GrantFiled: May 10, 1999Date of Patent: September 25, 2001Inventors: Alexander R. Provan, Toby R. Thomas, Eric A. St. Phillips

Patent number: 4528731Abstract: A slide fastener chain has a plurality of spaced separating regions along which the slide fastener chain can be separated or torn to slide fastener lengths one after another by hand without a cutting device. Each separating region extends transversely across the fastener chain and is at least partially thinned or recessed by fusing the thermoplastic synthetic materials of the fastener stringers at the prospective separating region.Type: GrantFiled: September 30, 1982Date of Patent: July 16, 1985Assignee: Yoshida Kogyo K.

Patent number: 4485533Abstract: A slide fastener chain comprises a pair of inter-engaged stringers including a pair of stringer tapes one longer than the other which have longitudinally staggered ends spaced from each other by a distance greater than the length of a slider which is to be mounted on the slide fastener chain. The coupling heads of a predetermined number of coupling elements on the longer stringer tape adjacent to the end of the shorter stringer tape and remote from the end of the longer stringer tape are cut off so that the coupling elements thus severed are kept uncoupled from opposite companion coupling elements on the shorter stringer tape. The slide fastener chain thus constructed can smoothly be threaded through the slider.Type: GrantFiled: December 22, 1982Date of Patent: December 4, 1984Assignee: Yoshida Kogyo K.K.Inventors: Kiyoshi Takeshima, Yoshinori Nakada
