Slider for zip fastener with two tabs and a single fork for releasing the slider

摘要

A slider (1) for zip fasteners with two tabs (2, 3), comprising a hollow body (4) in which are positioned structure (10, 5, 6) designed in such a way that, when either one of the two tabs (2, 3) is pulled, this causes the disengagement of a pawl (7) from the teeth (Zi) of a fastener, overcoming the resistance of elastic structure (8, 9) which keep the pawl inserted between the teeth (Zi). In the slider (1) a fork (10) is provided with two prongs (5, 6) positioned on opposite sides of the plane (β) of the teeth (Zi) and pivoted at a point (P, Q) of the slider (1) in such a way that it can rotate in a plane (α) perpendicular to the plane (β) of the teeth (Zi) when a force is exerted on at least one (6) of its prongs (5, 6) by the tab (3) connected to it by its ring (3a).
