A slider operable in a simple operation manner and capable of reducing an overall volume is provided. The slider includes: a slider body; a claw member positioned on the slider body and having a lock pin portion extending to an interior of the slider body to establish a locked state; an operation piece positioned on the slider body and connected to the claw member. The operation piece has first and second shaft portions that are separately positioned. The operation piece is rotatably positioned on the slider through the first shaft portion and connected to the claw member through the second shaft portion. Upon pressing the operation piece and enabling one side of the operation piece to rotate toward the slider with the first shaft portion as an axis center, the second shaft portion lifts the claw member to release the locked state in the interior of the slider body.

Slider

A slider includes a slider body part that includes an upper wing plate and a lower wing plate, a stop tab body, a tab elastic member that biases the stop tab body, a base part integrally formed with the upper wing plate, and an operation cover part rotatably attached to the base part. The operation cover part includes a pressing projecting part that projects from an inner surface of a top plate part, and the pressing projecting part has a configuration in which by rotating the operation cover part, a locked state and an unlocked state can be switched therebetween. Accordingly, since a stop mechanism by the rotation of the operation cover part can be provided in the slider with a relatively simple configuration, the manufacturing cost can be reduced and the productivity can be improved.

Slider for slide fastener

A slider for a slide fastener includes a body, a pull-tab, a control claw, and a cover. The control claw is placed on a shaft portion between a front attachment column and a rear attachment column. A protrusion length of a claw portion that enters an element path from a claw hole changes depending on an up-down position of the shaft portion so as to control movement of the body. The cover is attached to the front attachment column and the rear attachment column so as to be swingable in an up-down direction. The upper plate portion pushes the control claw downward due to a restoring force of a plate spring portion extending from a front end of the upper plate portion along a front surface of the front attachment column. The body, the pull-tab, the control claw, and the cover are separate components.

There is provided a slide fastener slider. A pull tab has a rotatable region including laid-down positions and a stood-up position. Within the rotatable region of the pull tab, a locking pawl is elastically deformed to move a cover portion, and a pawl portion is arranged to be inserted into and removed from an element guide passage in accordance with movement of the cover portion. When the pull tab is completely laid down toward the shoulder mouths and rear mouth relative to the slider body, the pull tab has respective regions in which the pull tab is rotatable over a predetermined angle without exerting any load on the locking pawl.

Slide fastener slider

A slider for a slide fastener is provided which is capable of quickly fastening and unfastening the slide fastener in a remote operation manner. A string having pull tabs on longitudinally opposite sides is fixed to a body of the slider for a slide fastener such that the string is not moved in the longitudinal direction.

Provided is a slider for slide fastener. A pull-tab has a cam portion, and when the pull-tab is rotated from a laid-down state where the pull-tab is laid down toward one side of a slider main body to an erected state, the pull-tab is urged with using the cam portion in a direction in which the pull-tab reruns to the laid-down state by an elastic force of a spring part. The slider has a restraining part configured to prevent the pull-tab from rotating further from the erected state and prevent the pull-tab from being laid down toward the other side of the slider main body.

Slider for slider fasteners

There is provided a slider for slide fastener. A pull tab holder body includes flanges extending in a width direction and a longitudinal direction. A slider body includes slide groove portions formed in a front end portion of an upper blade to receive the flanges. One of the pull tab holder body and the slider body has a protrusion portion protruding toward the other. The other of the pull tab holder body and the slider body has a recess portion. The flanges are inserted into the slide groove portions and upper surface portions of the upper blade located above the slide groove portions are crimped toward the flanges, so that the protrusion portion is engaged with the recess portion and the pull tab holder body is fixed to the slider body.

A slider for a slide fastener includes a stopper mechanism formed for 'forward use,' in which the surface where coiled fastener elements are attached on a fastener tape is the front surface, can be used for 'reverse use,' in which the surface where the coiled fastener elements are attached on the fastener tape is the back surface. The inner surface of the lower blade of the slider body of a slider has a protrusion that extends in the forward-reverse direction from a guiding bar towards a posterior opening. The protrusion has a first horizontal upper surface on the guide bar end of the protrusion that is highest and a second upper surface on the posterior opening end that is lower than the first upper surface.

Slide fastener and slider for slide fastener

A slider of the invention has a slider body and a tab, and first and second tab attachment posts of the slider body rotatably retain an attachment shaft portion of the tab. Further, a cover body covering at least the first and second tab attachment posts is fixed to an upper blade of the slider body. In accordance with this, since the slider has a good touch feeling and an improved outer appearance, it is possible to construct a slide fastener which is excellent in quality. Further, in the case that the slider has a stop mechanism, the stop mechanism can be protected by the cover body, and it is accordingly possible to prevent a trouble in the stop mechanism.
