Definitions

  • the present invention relates to the technical field of zip fasteners, and more particularly to those members known as sliders which close and open a zip fastener by respectively connecting and releasing from each other two rows of teeth which face each other and lie parallel to each other.
  • the invention relates to sliders of the type provided with two tabs, with connecting rings located on opposite sides of the zip fastener plane, one of these rings being pulled to move the slider in the desired direction by disengaging from the teeth a locking member which, when inserted between the teeth, prevents undesired movements of the slider.
  • the hollow body of the slider houses two interfering levers which are in contact with each other and are connected to the aforementioned rings of the said two tabs. These levers are positioned in such a way that, when either one of the two tabs is operated as stated, a locking pawl with which one of the two levers is provided is disengaged from the teeth.
  • the slider houses elastic means which reinsert the said pawl between the teeth when the action of one of the tabs on the said lever ceases.
  • these elastic means consist of an elastically flexible body mounted within the hollow body of the slider which is in contact with the lever carrying the previously described pawl in such a way that it opposes the movements of the said lever which cause the said pawl to be extracted from the teeth of the fastener.
  • the inventor of the slider to which the present application relates sought a simple, economical and reliable solution, and has devised a slider of the type described above, in which the previously described elastic means which cause the pawl to return to its locking position consist of an elastically flexible strip forming part of the said lever which terminates in the aforesaid pawl.
  • This strip has one end integral with the lever in question, and faces an internal wall of the hollow body of the slider, in such a way that it is interposed between this body and the said lever and its elastic resistance opposes movements of the lever which cause the aforesaid pawl to be extracted from the teeth of the fastener.
  • the object of the present invention is therefore a slider for zip fasteners with two tabs as described in the attached claim 1 .
  • FIG. 1 shows how the slider 1 with two tabs 2 and 3 according to the invention is similar to those of the known type in respect of the arrangement of its parts: two L-shaped levers 5 and 6 are positioned in a hollow body 4 , these levers interfering with each other and being in contact at one end, and housed on opposite sides of the area occupied by the teeth Di (shown only schematically in the drawing).
  • Each of the two levers 5 , 6 is connected to a ring 2 r , 3 r of the tabs 2 , 3 in such a way that pulling on either of the tabs (see FIGS. 2 and 3 ) causes, directly or indirectly, a rotation (arrow R) of one of the levers, indicated by the number 5 in the figures, which causes the extraction of a pawl 7 , in which it terminates, from the teeth Di between which it is interposed to lock the slider 1 as stated previously, thus preventing movements of the slider which may cause an undesired opening or closing of the fastener (which is not shown in full).
  • the lever 5 and strip 8 can advantageously be combined in one piece, as in the illustrated example, so that the lever and strip assembly can be produced in a single operation.
  • the inventor suggests that the levers 5 and 6 and the strip 8 be made from a metallic material, for example steel, with good characteristics of bending and fatigue resistance, or from a plastic material.
  • the strip 8 can be positioned as in the drawings, or can have one end integral with the free end 51 of the lever 5 carrying the pawl 7 (this embodiment is not illustrated).
