Zipper slider and zipper

Abstract

A slider is provided in which the amount by which the upper portion of the slider main body of the slide fastener protrudes upward relative to the pair of fastener tapes is reduced as much as possible. A slider for a zipper, characterized in that the slider for the zipper includes: a slider main body that is opposite to the lower surface of the left and right side edge portions of a pair of zipper tapes (21, 21) extending forward and backward. A pair of fixed element rows (22, 22) moves back and forth; a pair of support shafts (5, 5) protrude laterally from the left and right sides of the upper part of the slider body located above the pair of zipper tapes ; and a pull piece (6), which is supported on a pair of support shafts; the slider main body (4) has a chain element passage (45) on its front and rear surfaces for a pair of chain element rows to pass through, and the chain element passage (45) The front end of the slider is set as a pair of front openings (45a, 45a), and the rear end is set as a rear opening (45b). It has a pair of zipper tape grooves (46, 46) for a pair of zipper tapes to pass through, and the diameter (5d) of the support shaft<the maximum thickness dimension (t) of the upper part of the slider main body in the vertical direction<2.5mm.

Description

technical field [0001] The invention relates to a slider of a slide fastener and a slide fastener. Background technique [0002] The pair of element tapes of the slide fastener includes a pair of fastener tapes arranged in parallel on the left and right, and a pair of element rows along the left and right side edge portions of the pair of fastener tapes facing each other. Moreover, since the slider of a slide fastener is arrange|positioned so that it may cover mutually opposing left and right side edge parts of a pair of fastener tape, and a pair of element rows from both upper and lower sides, the slider has the part which protrudes upward rather than a pair of fastener tape. More specifically, the part of the slider that protrudes upward from the pair of fastener tapes includes a handle for operation, an upper part of the slider main body that engages with a pair of element rows, and a slider for moving the slider. The handle attachment part where the main body and the ha...

Problems solved by technology

However, Patent Document 1 does not disclose a specific numerical value indicating how far the upper portion of the slider body protrudes upward from the pair of fastener tapes, and of course does not disclose a value as a reference for estimating the specific numerical value.

In addition, in the slider disclosed in Patent Document 1, as described above, the upper surface of the slider main body is formed higher than the upper surface of the ring of the pair of arms held horizontally, which gives a thicker impression.
