The pull tab has a base portion, a gripper and a claw portion protruding from the base portion. The shaft member is configured to rotatably support the pull tab relative to the body. The coil spring is attached around the shaft member to urge the gripper to be laid down toward the body. A claw guide portion allows a tip end of the claw portion to protrude into the guide groove. A restricting portion of the body restricts rotation of the pull tab when the pull tab is raised by a predetermined angle from the body. A restricted portion of the pull tab comes in contact with the restricting portion when the pull tab is raised by the predetermined angle from the body.

Abstract: Open-ended slide fastener assemblies with improved operability. In some examples, the slide fastener assemblies are watertight and/or airtight. The slide fastener assemblies include one or more sliders and box and pin mechanisms integrated with the slide fastener. The pin mechanism need not be inserted into the box at the same time it is inserted into the slider, permitting the slide fastener to be operated even when it is not visible or easily accessible.

Abstract: A slide fastener includes a first tape with a plurality of first elements, a second tape with a plurality of second elements, and a slider element configured to interface with the first tape and the second tape. The slider element includes a body portion and a removable portion that are configured to selectively mechanically engage/disengage with one another.

Abstract: There is provided a buckle including a plug and a socket. The plug includes a plug-side base part, a pair of leg parts, and a pair of engagement protrusions. The socket includes a socket-side base part, an upper plate, a lower plate, upper side wall parts, lower side wall parts, engagement stepped portions, slits, and guide surfaces. A dimension of the pair of engagement protrusions in the upward and downward direction is set to be greater than a dimension of each of the slits in the width direction.

Abstract: A slider includes lower flanges placed on left and right side edges of a lower wing plate. Each of the lower flanges includes a downwardly inclined surface portion which is placed on the shoulder-opening-side tip portion on a side of its upper surface and on an outer side in a width direction of the slider, and which downwardly inclines toward a shoulder and downwardly inclines toward the outer side in the width direction of the slider. According to this, in a slide fastener having the slider, even if a sliding operation of the slider is repeated in the slide fastener, it is possible to avoid defects that the lower flange of the slider comes into sliding contact with the fastener tape and the fastener tape is broken, and it is possible to extend the life of the fastener tape.

Abstract: A fastening device includes a base including a top surface; a first fastening field extending from the top surface of the base and including a plurality of first fastening elements, each of the first fastening elements including a fastening feature, the fastening feature of at least some of the first fastening elements extending in a first direction; and a second fastening field extending from the top surface of the base and comprising a plurality of second fastening elements, each of the second fastening elements including a fastening feature, the fastening features of all of the second fastening elements extending in a second direction that is angled with respect to the first direction, the second fastening field divided from the first fastening field by a dividing line.

Abstract: This surface fastener has a substrate portion and a plurality of engaging elements, each of the engaging elements being provided with a stem portion standing from the substrate portion and a hook portion extending in the fastener width direction from the stem portion. The engaging element has a narrow width tip end portion provided with at least a hook portion and an enlarged width portion provided with only the stem portion, separated by a reference surface along the fastener length and height directions as a boundary. This makes an undercut hardly formable in the molding of the engaging element, and deficiencies such as deformation and the like of the engaging element can be prevented. Further, the strength of the stem portion can be increased, and a damage which a loop-shaped engaging element and the engaging element receive when the loop-shaped engaging element is attached or pulled out can be reduced.
