Abstract
A slider for zip fasteners with two tabs, includes a hollow body in which are positioned members designed in such a way that, when either one of the two tabs is pulled, this causes the disengagement of a pawl from the teeth of a fastener, overcoming the resistance of elastic elements which keep the pawl inserted between the teeth. In the slider, the members include a fork provided with two prongs positioned on opposite sides of the plane of the teeth and pivoted at a point of the slider in such a way that it can rotate in a plane perpendicular to the plane of the teeth when a force is exerted on at least one of its prongs by the tab connected to it by its ring.
Claims1
Slider for zip fasteners with two tabs, comprising a hollow body in which hollow body are positioned means designed in such a way that, when either one of said two tabs is pulled, this causes the disengagement of a pawl from the teeth of a fastener, overcoming the resistance of elastic means which keep the pawl inserted between said teeth, wherein said means comprise a fork provided with two prongs positioned on opposite sides of a first plane of said teeth and pivoted at a point of the slider in such a way that said fork can rotate in a second plane perpendicular to said first plane of the teeth when a force is exerted on at least one of its prongs by the tab connected thereto by its ring, and said pawl being formed on the free end of one of the prongs, an elastically compressible spring being inserted between said fork and the hollow body of the slider, said spring keeping the pawl inserted between the teeth of the fastener when no force is applied to the fork, each of said prongs being connected to one of the two tabs by the corresponding ring in such a way that, when either one of the two tabs is pulled, the fork is made to rotate in such a way so as to cause the disengagement of the pawl from the teeth of the fastener.
