experiment example 1

[0056] Using the slide fastener 1 to which the slider 110 of which the depth Dx of the recessed part 131B of the lower flap 130 was changed was applied, the bite performance was measured as follows. In addition, the following Comparative Example 1 and Comparative Example 2 (Sample S1 and Sample S6) deviate from the slide fastener 1 and its slider 110 of the present invention. The reference numerals of the slider 110 will be described (this is also the same for the experimental example 2 to be described later.).

[0057] The length TL of the front-back direction is 14.0 mm, and the sample S1 - the sample S6 of the slider 110 which differs in the depth Dx were prepared.

[0058] Sample S1 (Comparative Example 1): Depth Dx=0 mm

[0059] Sample S2 (Example 1): depth Dx=0.5mm

[0060] Sample S3 (Example 2): depth Dx=1.0mm

[0061] Sample S4 (Example 3): depth Dx=1.5mm

[0062] Sample S5 (Example 4): depth Dx=2.8mm

[0063] Sample S6 (Comparative Example 2): depth Dx=2.9 mm

experiment example 2

[0071] Next, will figure 1 The slide fastener 1 of the zipper was used in reverse, and the bite performance was measured as follows using the slide fastener 1 in which the depth Dx of the recessed portion 131B of the lower flap 130 was changed. Although not shown in the figure, the reverse slide fastener 1 used in Experimental Example 2 is a spiral slide fastener in which the spiral fastener element row 4 is attached to the back surface of the front and back surfaces of the fastener tape 3 . When the slide fastener 1 is reversed, the upper flap 120 and the handle 50 of the slider 110 are also arranged on the front side of the fastener tape 3 (the side without the element row 4 ), and the upper flap 120 and the handle 50 of the slider 110 are arranged on the back side of the fastener tape 3 (the fastener element The side on which row 4 is located) is provided with a lower flap 130 . In other words, the reverse use of the slide fastener 1 can be said to make figure 1 The sli...

Abstract

Provided is a slide fastener capable of reducing the seizure of a fabric by means of a slider itself without requiring the expansion of the slider. A slide fastener (1) is provided with: a pair of left and right fastener element tapes (2) having element rows (4) at opposing edges of left and right fastener tapes (3); and a slider (10, 110) that engages the element rows (4) by moving forward and releases the engagement between the element rows (4) by moving backward. A slider (10, 110) is provided with an upper wing plate (20, 120), a lower wing plate (30, 30A, 130), a guide post (11, 111), a Y-shaped element path (40), left and right shoulder openings (41), and a rear opening (42). The upper wing plates (20, 120) and the lower wing plates (30, 130) respectively have left and right front end sides (21a, 31a, 131a) that constitute the opening ends of the left and right shoulder openings (41). At least one of the upper wing plates (20, 120) and the lower wing plates (30, 30A, 130) has one or more recesses (31B, 31C, 131B) recessed rearward from the left and right front end sides (21a, 31a, 131a). The depths (D, Dx) of the recesses (31B, 31C, 131B) recessed rearward from the left and right tip edges (21a, 31a, 131a) are greater than 0 and are equal to or less than the distance to the end points (P, P1) of the arc lines of the guide columns (11, 111).

Description

technical field [0001] The present invention relates to a slide fastener, in particular to a slide fastener with a slider. Background technique [0002] Zipper is widely used in clothes, bags, tents, sleeping bags, etc. A slide fastener opens and closes between the element rows provided in each opposing edge part of a pair of left and right fastener element tapes by moving a slider to one side or the other side. That is, when the slider is moved to both shoulder openings (front openings), the left and right element rows are meshed to close the space between the left and right fastener element tapes, and when the slider is moved to the rear opening side, the left and right fastener elements The engagement of the row is released and the left and right zipper element belts are opened. In such a slide fastener, during the movement of the slider, for example, fabrics such as clothing may be bitten between the element row and the slider that have entered the slider from the left...
