Abstract: In a waterproof slide fastener, fastener elements are formed using a synthetic resin which contains a silicone resin or a fluorine-based resin, and a water repellant agent is applied to waterproof tapes and the fastener elements and hence, the waterproof slide fastener can exhibit a water-repellent effect brought about by the waterproof tapes and a water-repellent effect brought about by the fastener elements. Accordingly, it is possible to properly prevent the intrusion of a liquid through a gap formed between the left and right fastener elements and a gap formed between the fastener element and the waterproof tape.

Abstract: A fastener element 3 is attached to a first edge part 12 of a fastener tape 2 and the fastener tape 2 is sewn in the vicinity of the installation part 5 of the fastener element 3 with a sewing thread 6 continuously extending in the longitudinal direction of the fastener tape 2. The fastener tape 2 is easily subjected to plating to form a shield coating 7 or to coating of a fire-resistant additive and thus the fastener tape 2 can obtain electromagnetic wave shield performance and further fire-resistant performance.

Abstract: A slide fastener with a separable bottom end stop enabling a reinforcement portion of the separable bottom end stop to be sewed securely and ribs at a sewing position not to be damaged by a sewing needle. The reinforcement portion formed integrally on a lower half portion of each of a box pin and an insert pin of the separable bottom end stop using synthetic resin is exposed on the fastener tape and constituted of an auxiliary member and ribs formed at a sewing position to be sewed to a sewing object. The rib is formed like its height is 0.5 to 0.85 mm and width 0.6 to 0.9 mm, expanded gradually from a vertex to a base portion. A gap portion, wider than the base portion of the rib, is formed between adjoining ribs, therefore the rib avoids strike of a sewing needle not to be damaged thereby and the gap portion ensures sewing of the fastener tape onto the sewing object.

Abstract: This invention relates to a slide fastener with a separable bottom end stop which scatters an external force applied to a reinforcement portion upon the opening/closing operation to reduce an applied load thereby preventing damages to the flexible reinforcement portion. Reinforcement portions are formed on a lower half of a box pin and an insert pin of a separable bottom end stop with synthetic resin symmetrically on front and rear surfaces of a fastener tape such that the reinforcement portions are extended on the fastener tape. Each reinforcement portion has an inside portion adjacent to the box or insert pin and an outside portion connected thereto. In the inside portion, plural ribs are disposed obliquely and a concave portion is formed among the ribs to supply flexibility. The outside portion is formed of thick ribs and connects with the inside portion.

Abstract: A slide fastener having a separable bottom end stop is provided, which comprises a high quality reinforcement piece in which flexibility thereof is improved and there is no stripping or breakage of the reinforcement piece. Reinforcement pieces overhanging on front surfaces of fastener tapes are provided on side faces of the box pin and insert pin. Each reinforcement piece comprises an inclined portion which is formed in a substantially triangular shape overall toward an outer side edge close to a lower end of each fastener tape. An edge portion of the inclined portion is formed as a slope portion, which slopes gently toward a front surface of the fastener tape.

Abstract: In a fastening device with tape, a synthetic resin first member is integrally molded on front and back surfaces of a tape having at least one attachment hole in such a manner as to hold an entire peripheral edge portion of the attachment hole of the tape and has an opening portion at a center thereof, and then a synthetic resin second member is attached, by molding or the like, to the first member along an inner peripheral surface of at least the opening portion of the first member and has an engaging portion to be engaged with an opposing fastener.

Abstract: In a fastening device with tape, made of synthetic resin, the tape is composed of a warp knitting structure including an attachment area composed of one or more wales disposed at the right and left edge portions in a width direction of the tape, and a fastener-molding area composed of plural wales in a center portion in the width direction of the tape. The warp knitted tape is entirely composed of a knitting structure by tangling of two needle stitch yarns and weft in-laid yarns. A chain stitch yarn is further knitted into the attachment area so as to suppress the stretching property an stabilize dimensional form in the warp direction of the attachment area. In the fastener-molding area, a predetermined stretching property in the warp direction and some extent of stability in dimensional form are secured. The fastening device can be adapted well to an attachment object such as clothes having a stretching property and may be engaged or disengaged securely and accurately.

Abstract: A tape of the fastening device made of synthetic resin is composed of an attachment area formed of one or more wales disposed at right and left edge portions of the tape in the width direction thereof and a fastener-molding area formed of plural wales in a center portion in the width direction. The warp knitted tape is entirely composed of a knitting structure formed by tangling of tricot stitch yarns and single cord stitch yarns, and chain stitch yarns are further knitted in the fastener-molding area so as to suppress stretching property in a warp direction of the area to a maximum extent and ensure a dimensional stability. The attachment area is composed of a knitting structure having required stretching property in its warp direction and some extent of stability in the dimensional form. Therefore, the fastening device with tape can be sewed to and along a curved line easily and can be adapted to an attachment object having stretching property well.

Abstract: A fastener with tape has fastening members of synthetic resin molded integrally and firmly on front and rear surfaces of the tape so as to enclose an entire peripheral portion of a mounting hole of the tape having at least a mounting hole. The fastening members are made of synthetic resin material to which fine inorganic filler is added. The stiffness and the elasticity of the fastening members change depending on the kind and the addition amount of the inorganic filler.

Abstract: The present invention provides a slide fastener in which a normal engaging state of engaging elements can be maintained, even if right and left tensile loads are applied to the engaged elements having an engaging male portion and an engaging female portion which can be engaged with and disengaged from each other in upward and downward directions.
