Abstract: A cord lock for adjusting the length of a cord includes a main body with a through hole, in which a cord can be inserted. A friction member is blocked in the main body in such a manner that a portion of a tooth thereof narrows the gap of the through-hole in order to limit the sliding of the cord.

Abstract: A snap button includes a male component and a female component which couple and uncouple as a result of effort in a main axial direction. The male component has a base from which there protrudes a rounded head, which is provided with a neck which is narrower than the head. The female component has a hollow body with an opening within which the head of the male component is introduced. Two flexible bars of a plastics material are mounted in the hollow body, the flexible bars having the ends thereof blocked. The distance between the central zones of the two flexible bars is lower than the dimension of the head of the male component so that they can be flexibly forced away from each other by a force exerted by the head of the male component and to resiliently move back towards each other when the force stops.

Abstract: A press stud comprises a male element and a female element. The male element comprises a coupling portion which is insertable into a housing seat of the female element in a coupling direction. The coupling portion of the male element has an anti-uncoupling appendage which interferes with the female element and prevents the uncoupling of the male element from the female element when they are subjected to tension acting in a substantially transverse direction with respect to the direction of coupling.

Abstract: A press stud comprises a male element and a female element, which show, when coupled, a capacity for mutual transverse displacement with respect to the coupling direction to move, when subjected to tension acting in a substantially transverse direction with respect to the coupling direction, from an uncouplable position to a locked position. An elastic centring member exerts an elastic force on the male element and/or on the female element to keep them in the uncouplable position in the absence of tension acting in a substantially transverse direction with respect to the coupling direction.

Abstract: A female component of a press stud including a monolithic body made by hot forming and defining a housing seat for a retaining member housed in the housing seat and intended to lock a corresponding male component in position selectively during use. A locking lip, integral with the monolithic body, extends from the housing seat and is deformed so as to partially close the housing seat in order to secure the retaining member therein. In order to produce the female component, the monolithic body is hot formed, and the locking lip is deformed after the introduction of the retaining member into the housing seat, by hot or cold crimping, upsetting or deformation in general.

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.

Abstract: A slider for a zip fastener with two tabs, includes a hollow body in which are housed two levers positioned on opposite sides of the teeth of the fastener, one of the two levers, provided with a pawl for insertion between the teeth to lock the slider, being operable by acting on either one of the tabs to overcome the resistance of an elastic element positioned within the hollow body which keeps the pawl inserted between the teeth. The elastic element includes an elastically flexible strip, having one end fixed to the lever provided with the pawl, the strip facing an internal wall of the hollow body in such a way that it is interposed between the body and this lever and its elastic resistance opposes a movement of the lever which causes the extraction of the pawl from the teeth.
