A slide fastener of the present invention includes: a first fastener stringer; a second fastener stringer; and a slider which couples or separates the first and second fastener stringers, in which the second fastener stringer separated from the slider is inserted into the slider wherein the first fastener stringer and the second fastener stringer are coupled in a vertical direction. Accordingly, a row of fastener elements of the second fastener stringer separated from the slider is inserted into the slider by first and second fastening members when a fixing pin and an insertion pin are coupled in a vertical direction, and as a result, the coupling operation is convenient.

The prevent invention provides a zipper head assembly structure and a slidable element thereof. The sliding element has a base portion, two lateral wall portions, and a seat portion. The base portion has a front side and a back side. The two lateral wall portions are respectively upwardly extended from two opposite lateral sides of the base portion, and the two lateral wall portions correspond to each other and are connected to the front side of the base portion. The seat portion is disposed on the base portion and connected to the back side of the base portion. The seat portion has a main body disposed on the base portion and connected to the back side of the base portion, two strip convex ribs respectively disposed on two opposite sides of the main body, and two concave spaces respectively connected to the two strip convex ribs.

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.

A bungee bead apparatus includes a bead and elastic cord with first and second ends fixedly secured in proximity to, or in contact with, each other at one end of the bead to form a loop. A circumferential recess formed between first and second sides of the bead extends from the bead's first end to its second end, having a cross-sectional height and width to receive the loop of the elastic cord therethrough. The orifice extends at an acute angle, positioned midway between the bead's first and second sides, and begins at the bead's first end in proximity to the first side, and transects the circumferential recess at its second end. The circumferential recess is annular with a depth of about one-half the diameter of the cylindrical elastic cord to receive only a portion therein. The recess and orifice permit two (or more) such apparatus to be linked together.

The invention involves a securable slider assembly for a zipper. The securable slider assembly is formed in a single die cast operation to include the securable slider and the pull being formed simultaneously. At least one side shifting slide is incorporated into the die, which allows the bridge and pull loop to be formed with their full geometric shape and without the converging flat surfaces required in the prior art. The slide assembly includes a puller that includes geometry to allow two slides to be secured together after the closing operation of the zipper teeth and restricts the ability to separate the pullers for opening of the zipper teeth to provide security to the user.

A slider for a slide fastener in which the slider is attached to fastener chains is provided. The slider includes a first member and a second member. The first member includes an upper blade, a lower blade, a guide post connected between the upper blade and the lower blade, and a connecting post protruding from the upper blade. The second member includes a first arm and a second arm separated from each other, is attached to the first member by the first arm and the second arm, and is configured to rotate along an upper-lower direction relative to the first member and around a fulcrum provided on the upper blade or the lower blade. The first member or the second member is provided with a flange. Three or more fit sections are formed between the first member and the second member.

The circumferential recess is annular with a depth of about one-half the diameter of the cylindrical elastic cord to receive only a portion therein. The recess and orifice permit two (or more) such apparatus to be linked together.

Pull tab (90) includes a pull tab main portion (92). First base (61) is sandwiched between a second base (62) and the pull tab main portion (92) to form a stack (105) in which the second base (62), the first base (61) and the pull tab main portion (92) are stacked in this order. The pull tab main portion (92) and the first base (61) are configured such that the pull tab main portion (92) moves rearward to cause rearward movement of the slider body (40) as the stack (105) is sandwiched by human fingers in its stack direction while the first insert (71) has been not fully inserted inside the slider body (40).

“A slide (100) for a zip fastener has a hasp (115) and a pull tab (120). This assembly is being moulded into a single block. The pull tab (120) has an eyelet (121) for connecting to the hasp of the slider. The pull tab (120) has a locking eyelet (122) the opening plane of which is parallel to the opening plane of the connection eyelet (121). The pull tab (120) has a portion (125) for connection between the two eyelets (121, 122), called the pull tab body, the width of the cross-section of the pull tab body in a direction perpendicular to the opening planes of the eyelets is greater than or equal to the height of the cross-section in the plane parallel to the opening planes of said eyelets.”

A plastic product disposed on a strap is provided. The strap is a soft string type textile. The plastic product includes a first injection molding portion and a second injection molding portion. The second injection molding portion is combined with the first injection molding portion to form the plastic product. An end portion of the strap protrudes out of the first injection molding portion and is completely covered by the second injection molding portion. A length of the first injection molding portion along a longitudinal direction of the strap is less than a length of the plastic product along the longitudinal direction of the strap. A protruding length of the end portion of the strap protruding out of the first injection molding portion along the longitudinal direction of the strap is less than half of a thickness of the second injection molding portion along a radial direction of the strap.
