摘要： A slide fastener includes first and second stringers, an intermediate body, a first slider, and a second slider. The first and second stringers are separated by a first lateral distance in a first longitudinal portion, the first and second stringers are separated by a second lateral distance in a second longitudinal portion. A transition portion extending along at least a portion of a longitudinal extent of the intermediate body interposes the first and second longitudinal portions, and the second lateral distance is greater than the first lateral distance.

摘要： The molded surface fastener has a base portion, right and left resin-intrusion-preventing wall portions standing on the base portion, and a plurality of engaging elements disposed between the right and left resin-intrusion-preventing wall portions. The resin-intrusion-preventing wall portions contain magnetic particles, and at least a part of a region formed of the resin-intrusion-preventing wall portions and the base portion has a concentration gradient portion in which a concentration of the contained magnetic particles is decreased toward at least one direction. This makes it possible to enhance the adhesion property between the part containing the magnetic particles and the part substantially containing no magnetic particles, and to suppress occurrence of cracks or the like between the containing part and the non-containing part of the magnetic particles at the time of manufacturing the molded surface fastener and at other times.

摘要： Provided is an injection-molded resin button, which does not crack or is unlikely to crack at attaching the button to a fabric. This invention relates to a button including a button body having a through-hole at the center thereof. The button body of the button includes a left half part and a right half part, which are segmented left and right by a virtual straight line passing through a gate position, on the button body, corresponding to a gate of a mold for molding the button and the center of the button body. The button body includes one or more concave portions or one or more convex portions on an outer surface of the button body. The button is characterized in that the concave portions or the convex portions are provided asymmetrically in the left and right half parts. The button body includes a nonlinear weld line at least on the outer surface.

摘要： A method for sewing a slide fastener includes forming end edge portion needle drop points in at least two positions, within an overlapped portion in which the work piece is folded, within a range more toward a tip side of an end edge portion of the work piece than half of an overlapped width, and within a range on an inner side of a width of a leg portion of an interlocking element. Sewing is performed with sewing thread passing from a head portion needle drop point to the end edge portion needle drop point of one end portion and sewing thread passing from the end edge portion needle drop point of another end portion to the head portion needle drop point of an adjacent interlocking element each passing either side of the leg portion.

摘要： A buckle with a string adjustment portion includes a plug and a socket. The plug includes: a tightening string member attachment portion configured to slidably lock a string member and adjust a length of the string member; and leg portions which are inserted into and engaged with the socket. The socket includes a fitting portion including an insertion opening. An insertion hole through which the string member is inserted is formed to penetrate the tightening string member attachment portion, and a portion connecting the leg portions side of the insertion hole serves as a second bar. The second bar is located on an insertion direction side of the leg portions with respect to a position where an end portion of the plug and the insertion opening of the socket are abutted against each other, in a state where the leg portions are engaged with the socket.

摘要： Stop member includes: a first member including a first insert to be inserted into a slider via a rear mouth of the slider, and a first base positioned rearward of the first insert; and a second member including a second insert to be inserted into the slider via a slit extending between the rear mouth and a front mouth of the slider, and a second base to be overlaid onto the first base. The first and second bases are configured to effect magnetic attraction and/or repulsion between the first and second bases when the first and second bases are overlaid. The second base rotates relative to the first base in accordance with the magnetic attraction and/or repulsion to allow the second insert to pivot toward the slit.
