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

Slider (1, 11) for zip fasteners with two tabs (2, 3), comprising a hollow body (4) in which hollow body are positioned means (10, 20, 5, 6, 15, 16) designed in such a way that, when either one of said two tabs (2, 3) is pulled, this causes the disengagement of a pawl (7, 17) from the teeth (Zi) of a fastener, overcoming the resistance of elastic means (8, 9) which keep the pawl inserted between said teeth (Zi), characterized in that said means consist of a fork (10, 20) provided with two prongs (5, 6, 15, 16) positioned on opposite sides of the plane (β) of the aforesaid teeth (Zi) and pivoted at a point (P, Q) of the slider (1, 11) in such a way that it can rotate in a plane (α) perpendicular to said plane (β) of the teeth (Zi) when a force is exerted on at least one (6, 16) of its prongs (5, 15, 6, 16) by means of the tab (3) connected to it by its ring (3a), and wherein one (2) of the two tabs (2, 3) is connected to an elastic strip (8) terminating in said pawl (7) in such a way that it can disengage the pawl from the teeth (Zi), and the other tab (3) is connected to a prong (6) of the fork (10), the other prong (5) facing said elastic strip (8) in such a way that a rotation (R) of the fork (10) caused by the aforesaid other tab (3) also causes the said disengagement from the teeth (Zi) as a result of the movement of said other prong (5).
