In at least a part of a movable range of a slider, a slider upper portion is positioned adjacent to a wall upper portion, and a slider lower portion is positioned adjacent to a wall lower portion. This prevents jamming of a cloth in the slider at both sides of the tape upper and lower surfaces.

A switch assembly for engaging a switch of an electronic device includes a rotatable knob having an axis of rotation, a pin mechanism engaged with the rotatable knob, and a slider body. The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob. The slider body is shaped to include a slot in which the pin of the pin mechanism is positioned and a switch recess shaped to receive and selectively contact the switch of the electronic device. Rotation of the rotatable knob in a first direction causes the slider body toward contact with a first portion of the switch to urge the switch into a first position, and rotation of the rotatable knob in a second direction causes the slider body toward contact with a second portion of the switch to urge the switch into a second position.

An anti-pinch zipper includes two zipper tapes and a zipper slider. The inner side of the chain cloth of each zipper tape is folded back to the front to form a chain belt portion and a sliding space. The zipper slider has a top plate that holds the pull tab and is provided with a structure to guide the two rows of teeth of the zipper tapes to be interlocked with each other. The rows of teeth and the chain belt portions are passed through the zipper slider, so that the top plate and the pull tab are located on the front of the zipper, and the two chain cloths cover the back of the zipper slider.

Provided is a slide fastener that can reduce the biting of a fabric by the slider itself without unnecessarily expanding the size of the slider. A slide fastener (1) comprises: a pair of left and right fastener stringers (2) each having an element row (4) at each of opposing edge portions of left and right fastener tapes (3); and a slider (10, 110), the slider (10, 110) being configured to engage the element rows (4) by moving forward between the pair of left and right fastener stringers (2) and to disengage the element rows (4) by moving backward. The slider (10, 110) comprises: an upper wing plate (20, 120); a lower wing plate (30, 30A, 130); a guide pillar (11, 111) for connecting the upper wing plate (20, 120) to the lower wing plate (30, 30A, 130); a Y-shaped element path (40) defined between the upper wing plate (20, 120) and the lower wing plate (30, 30A, 130); left and right shoulder openings (41) that are open forward the element path (40); and a rear opening (42) that is open backward the element path (40). Each of the upper wing plate (20, 120) and the lower wing plate (30, 30A, 130) has left and right front end sides (21a, 31a, 131a) that form opening ends of the left and right shoulder openings (41). At least one of the upper wing plate (20, 120) and the lower wing plate (30, 30A, 130) has one or more concave portions (31B, 31C, 131B) recessed backward from the left and right front end sides (21a, 31a, 131a). A depth (D, Dx) of each of the concave portions (31B, 31C, 131B) recessed backward from the left and right front end sides (21a, 31a, 131a) is larger than zero, and less than or equal to a distance to each of end points (P, P1) of R of the guide pillar (11, 111).

There is provided a slide cover for a slide fastener. A pair of second guide element passages are formed in a space among an upper plate, a lower plate, a pair of outer wall portions and a pair of inner wall portions to guide a pair of separated element rows into a first element guide passage of a slider. The upper plate, the lower plate and a connection post have a concave surface, which is recessed in a disengaging direction of the slider, in a surface facing toward an engaging direction of the slider. The pair of second guide element passages are configured so that tip ends of the pair of inner wall portions in the engaging direction are located at the same positions as or at a side of the engaging direction relative to tip ends of the pair of outer wall portions in the engaging direction.

A child resistant zipper closure for a plastic bag includes a double slider, including a first slider and second slider. The first and second sliders are oriented on the zipper closure such that when at least one of the first slider and second slider is moving in a direction toward the other of the first slider and second slider, the zipper is interlocking; and when at least one of the first slider and second slider is moving in a direction away from the other of the first slider and second slider, the zipper is unlocking. The first and second sliders can be realeasably connected together.

There is provided a slider cover for a slide fastener. An upper member and a lower member are spaced apart from each other in an upward and downward direction and arranged in parallel to each other. A connecting post connects the upper member with the lower member. The upper member includes a receiving portion configured to receive at least a part of an upper blade of a slider.

A slider for a zipper closure includes a separator plow that is positionable between interlocking tracks of the zipper closure to open the zipper closure by pivoting an opening end of the slider in a direction toward a notch to position the plow between the interlocking closures. The slider can be disengaged by pivoting the slider so that the plow is outside of the interlocking tracks.

A slider for a waterproof slide fastener includes an upper blade and a lower blade opposing each other in an up-down direction, and a connecting post connecting the upper blade with the lower blade. Each of opposing surfaces includes a close-contact surface for sandwiching and close-contacting with a first stop in the up-down direction. At least one of the opposing surfaces includes right and left inclined surfaces provided respectively on right and left sides at a front sides of the close-contact surface and inclined in a direction widening a gap between the upper blade and the lower blade as the right and left inclined surfaces go forward. The at least one of the opposing surfaces includes an extended close-contact surface provided between the right and left inclined surfaces and extending forward from the close-contact surface.

A switch assembly for engaging a switch of an electronic device includes a rotatable knob having an axis of rotation, a pin mechanism engaged with the rotatable knob, and a slider body. The pin mechanism includes a pin, the pin being offset from the axis of rotation of the rotatable knob. The slider body is shaped to include a slot in which the pin of the pin mechanism is positioned and a switch recess shaped to receive and selectively contact the switch of the electronic device. Rotation of the rotatable knob in a first direction causes the slider body toward contact with a first portion of the switch to urge the switch into a first position, and rotation of the rotatable knob in a second direction causes the slider body toward contact with a second portion of the switch to urge the switch into a second position.
