Slide fastener with separable bottom end stop

摘要

This invention relates to a slide fastener with a separable bottom end stop which scatters an external force applied to a reinforcement portion upon the opening/closing operation so as to reduce an applied load thereby preventing the reinforcement portion having flexibility from being damaged. Reinforcement portions (10) are formed on a lower half of a box pin (8) and an insert pin (9) of a separable bottom end stop (5) with synthetic resin symmetrically on both front and rear surfaces of a fastener tape (3) such that the reinforcement portions are extended on the fastener tape (3). Each of the reinforcement portions (10) is constituted of an inside portion (11) adjacent to the box pin (8) or the insert pin (9) and an outside portion (12) connected thereto. In the inside portion (11), plural ribs (13a) are disposed obliquely and a concave portion is formed among the ribs (13a) so as to supply with flexibility. The outside portion (12) is formed of thick ribs (13b) such that it is connected to the inside portion (11). Consequently, an external force applied to the reinforcement portion is scatted by the oblique ribs (13a) in the thin inside portion (11), thereby reducing the applied load.
