text: More particularly, the slide fastener of these Japanese patent applications exhibits stabilized function with proper and smooth sliding resistance of the slider as the slide fastener is opened and closed.
text: The teeth are now ‘just’ visible when the zipper is open
text: On the other hand, the presence of the spacer means 9 adjacent to the free ends of the legs 7 causes the spacer means 9 to deviate from the neutral axis P of the fastener element row 2 and as a result, when the slide fastener is opened and closed, the degree of expansion and contraction of the spacer means 9 increases whereby the sliding resistance of the slider increases and the spacer means are easily subjected to fatigue fracture.
text: 2 through 7) so that the spacer means 9 can bend easily as the slide fastener is opened and closed and the sliding resistance of the slider is reduced.
text: Furthermore, since similar spacer means and connecting threads are present in the upper and lower positions between the legs of the adjacent fastener elements and each of the upper and lower spacer means has a minimum cross sectional area in the central portion thereof and increases the cross sectional area towards the opposing walls of the adjacent fastener elements, the central portion of the spacer means having the minimum cross sectional area bends easily as the slide fastener is opened and closed whereby the sliding resistance of the slider can be reduced.
text: The slide fastener is opened and closed by the movement of a slider.
text: An additional problem is that since the slider has no positive stop, the slider on the closed slide fastener is likely to slip off the top stop under a relatively strong force imposed on the slider, frequently allowing the slide fastener to be opened undesirably.
text: The top stop 19 is made of an elastomeric material such as rubber and has a substantially horseshoe-shaped body 23 extending around a peripheral edge 24 (FIGS. 4 and 5) of a terminal opening 25 which communicates with the opening 12 when the slide fastener 10 is opened, as shown in FIG.
text: For this reason, when a slide fastener is opened by sliding a slider downward, the slider flanges come into contact with the bottom stopper portion, so that the slider cannot slide any more.
text: The slide fastener 10 is opened/closed by sliding the slider 14 forward and backward.
text: When the slide fastener is opened or closed by operating a slider (not shown), the existence of this protrusion 9 increases a striking area of the stopper portion thereby contributing to providing the stopper portion with a secure stop function.
text: In practice, a pair of these identical stringers 10 are used to constitute a slide fastener which is opened and closed by a slider S (FIG. 3) movable along the rows of coupling elements 11 to take the latter into and out of interengagement in a manner well known in the art.
