A slider includes a slider body, a tab, and a cover member that is elastically deformable, the slider body has a front attachment post and a rear attachment post standing up from an upper blade, the front attachment post and the rear attachment post have a pair of first side wall portions and a pair of second side wall portions arranged on an outside of the first side wall portions in a length direction, outer wall surfaces of the second side wall portions are arranged on an inside of the first side wall portions via step portions in a width direction, at least a part of the outer wall surfaces of the second side wall portions faces inner wall surface of the cover member. This enables the cover member to be made more difficult to tilt in the width direction even if the cover member receives force.

Slider for slide fastener

A slider includes: a slider body including an upper vane, a lower vane, and a guide post connecting the upper vane and the lower vane; and a pull tab connected to the slider body. The upper vane is provided with a pair of lateral walls projecting from an upper surface of the upper vane in a thickness direction of the slider body. A connection bearing for a connecting pin supported by the pair of lateral walls to be inserted is provided to the pull tab. The upper vane is provided with a recess dented toward the lower vane in the thickness direction with respect to the upper surface. The connection bearing is located in the recess between the pair of lateral walls.

A slider includes a resin-made slider body, a pull tab, and a metallic connecting pin. Lateral walls of the slider body and the pull tab are provided with shaft holes in which the connecting pin is inserted. The shaft holes of the lateral walls are opened on outer side surfaces of the lateral walls to define openings, a bottom edge point of each of the openings being located at a position outer in a Y-axis direction than a top edge point above the bottom edge point.

Provided is a polyamide resin composition that is suitable as a material for slide fastener parts having good strength after being dyed. A polyamide resin composition for a slide fastener, comprising a polyamide resin and reinforcing fibers, wherein a total mass of the polyamide resin and the reinforcing fibers is 90% by mass or more of the composition; wherein a proportion of an aromatic polyamide having a melting point of from 200 to 250&#xb0; C. in the polyamide resin is more than 70% by mass; and wherein a content of the reinforcing fibers in the total mass of the polyamide resin and the reinforcing fibers is from 45 to 70% by mass.

There is provided a slider for a slide fastener. The slider includes a slider body, an elastic body and a pull tab. The pull tab includes a shaft, a pull tab main body and a cam. The cam is configured to elastically deform the elastic body when the pull tab is laid down. The slider body includes an upper blade and a pair of pull tab attaching posts. The upper blade includes a recess portion and a crimping portion. The recess portion includes a pair of lateral recess portions and a center recess portion. The crimping portion protrudes from at least one of the lateral recess portions at a protruding location located at a center side relative to both front and rear ends of the center recess portion.

A slider for slide fastener has a slider body in which an upper wing and a lower wing are coupled via a coupling pillar at the front side. At the front part of the upper wing, provided is a downward slope descending toward the lower wing as extending away from a front mouth toward a back mouth of the slider body. At the front part of the lower wing, provided is an upward slope ascending toward the upper wing as extending away from the front mouth toward the back mouth of the slider body. The downward slope of the upper wing is steeper than the upward slope of the lower wing.

Engaged portions formed on a tab holder are elastically engaged and attached to engaging portions formed on a first column portion and the rear side of a second column portion on an upper blade, and a pair of protrusions formed on the inner side of the tab holder are fitted in a recession formed on an inclined surface of the first column portion and a recession formed on an inclined surface of the second column portion. Further, stepped portions formed at both edge portions of both front and rear ends of the tab holder are brought in contact with end surfaces and inner sides of support walls installed at both edge portions of inclined surfaces. The slide fastener can improve attachment strength of the tab holder, implement excellent durability for a long period of time, excellent external appearance, and excellent assembly performance.

A slider for slide fasteners having a slider body with the leading end of the upper and lower plates connected by a connecting bar and a y-shaped element guiding path disposed between the upper and lower plates, a pull with one end rotatably held on the upper plate, and a stopping hook disposed on the upper plate and having a hook at one end; the upper plate having an insertion groove for inserting the stopping hook, a locking part for locking the other end of the stopping hook, and a hook eyelet drilled so that the hook can be inserted; and the stopping hook is disposed so that by tilting/erecting manipulations of the pull, the hook can be inserted/withdrawn from the element guiding path through the hook eyelet; wherein the corners of the stopping hook that contact the locking part, at least during locking operation, form beveled parts.

A slide fastener according to the invention includes a left-and-right pair of first and second fastener stringers, a box pin provided on the first fastener stringer, an insert pin provided on the second fastener stringer, and a pair of first and second sliders. The box pin has a box pin body, a stopper portion, and a ridge portion formed on the box pin body. Further, a chamfered portion is formed on an inner surface of at least one of the upper and lower wing plates of the first slider. The ridge portion is arranged at a position in close contact with the chamfered portion of the first slider when the first slider is stopped at the stopper portion. With this arrangement, it becomes possible to cause the user to be accustomed to securely slide the first slider to the normal insert-pin inserting position.

Slide fastener

A slider has an upper blade of a slider body having an insert groove of a locking pawl, a temporary engagement portion for which temporary engages and fixes the locking pawl, and a claw hole. The temporary engagement portion is adapted so that, with the locking pawl fixed in position, the position in height of the upper end of the temporary engagement portion is the same as or lower than that of the upper surface of the upper blade. This prevents the temporary engagement portion from being pressed and crushed when the temporary engagement portion is in contact with the tab and so on. As a result, an automatic stop mechanism of the slider can stably function.

A slide fastener includes a pair of first and second fastener stringers, a box pin, an insert pin, and a pair of first and second sliders. The box pin has a box pin body, a stopper portion arranged at a front end side of the box pin body, and suppressing portions projected on at least one of upper and lower surfaces of the box pin body to suppress sliding of the second slider. Further, the box pin body has a body region, and a notched region arranged at an element-row-side base end portion and having excluded a side surface portion at a side facing the insert pin. The suppressing portions are projected in only the notched region. With this arrangement, the second slider can be stably held at an insert-pin inserting position, and a subsequent insert operation or extract operation of the insert pin can be smoothly performed.
