Definitions

  • the present invention relates to a selvage for an electric or mechanical lock with a pivot for a pawl engagement system.
  • the casing contains the electric elements that are designed to actuate other mechanical elements that close and open the lock.
  • a hook-shaped retention element surrounds the pivot, rigidly coupling the casing to it.
  • the selvage is constituted by a rear plate for fixing to the fixed structure, to which two links are pivoted, said links having, at their other end, respective aligned through holes that rotatably accommodate the ends of the pivot.
  • the pivot can rotate about its own axis and can oscillate over a short arc of a circle traced by the freedom of rotation of the two links with respect to the rear fixing plate.
  • the leaves on which this type of lock is normally installed are heavy, since they are in fact gates, main doors and the like; often the weight of these leaves, over time, deforms the hinges or more simply displaces them slightly.
  • the leaf tilts as an immediate consequence.
  • the tilt of the leaf causes the less than perfect mechanical coupling between the pivot (the selvage is installed so that the axis of said pivot is vertical) and the hook-shaped retention element, which has the same inclination as the leaf, since it is rigidly coupled thereto.
  • the aim of the present invention is to obviate the above-cited drawbacks and to meet the above-mentioned requirements, by providing a selvage for an electric or mechanical lock with a pivot for a pawl engagement system with which it is possible to close the lock even when the leaf is slightly tilted.
  • an object of the present invention is to provide a selvage that is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost.
  • the reference numeral 1 generally designates a selvage for an electric or mechanical lock with a pivot for a pawl engagement system.
  • the selvage 1 is fixed to the wall or frame by means of the rear plate 2, which has holes 3 for anchoring by means of screws, screw anchors or the like.
  • Two links 4 are pivoted to the plate 2, respectively in an upper region and in a lower region along a same pivoting axis; said links are provided respectively with a through hole 5 in their free end, i.e., the one that lies furthest from the pivoting axis.
  • the rear plate 2 has rotation stroke limits 6 that limit the movements of the links 4.
  • the pivot 7 is substantially cylindrical and has regions with a smaller diameter at its two ends 8; said narrower ends 8 engage in the holes 5 of the links 4, providing a play 9 by way of this coupling.
  • the pivot 7 is firmly retained inside the holes 5 as a consequence of the forcing of respective heads 10 that have a larger diameter than the holes 5, or by means of elastic rings, the heads 10 therefore constituting a shoulder.
  • the pivot 7 can move parallel to itself and to the pivoting axis of the links 4 and can rotate about its own axis by way of the shape of the couplings of the links 4 with the plate 2 and of the pivot 7 with the links 4.
  • the play 9 provided in the coupling of the pivot 7 to the links 4 further allows the pivot 7 to tilt its own axis with respect to the pivoting axis of the links 4.
  • the inclination of the pivot 7 allows the coupling of the pivot 7 to the electric or mechanical lock with pawl engagement system even when said lock is fitted on a tilted inclined leaf: the pivot 7, too, can in fact tilt in order to cope with the different angle of insertion in the lock produced by the tilt of the leaf.
  • the pivot 7 can be cambered, said shape being suitable to constitute a guide for the engagement of the lock if said lock is tilted.

Claims (4)

  1. Gâche pour serrure électrique ou mécanique avec un pivot (7) pour un système d'encliquetage, comprenant une plaque arrière de fixation (2) dans laquelle deux articulations (4) à trous traversants (5) sont amenées à pivoter de manière coaxiale et indépendante, lesdits trous recevant à rotation les extrémités (8) dudit pivot (7), caractérisée en ce que le diamètre desdites extrémités du pivot (7) est plus petit que le diamètre desdits trous (5), produisant un jeu mécanique (9) qui permet audit pivot (7) d'incliner son propre axe par rapport à l'axe de pivotement desdites articulations (4)
  2. Gâche selon la revendication 1, caractérisée en ce que ledit pivot (7) est sensiblement cylindrique, ses extrémités (8) ayant un diamètre plus petit et se prêtant à être reçues dans lesdits trous (5) des articulations (4).
  3. Gâche selon une ou plusieurs des revendications précédentes, caractérisée en ce que des têtes respectives (10) s'ajustent sur lesdites extrémités (8), ont un plus grand diamètre que lesdits trous (5) et servent à empêcher le pivot (7) de sortir desdits trous (5).
  4. Gâche selon une ou plusieurs des revendications précédentes, caractérisée en ce que ledit pivot (7) a, en son centre, une zone cambrée afin d'assurer un meilleur accouplement avec ledit système d'encliquetage de la serrure quand ladite serrure est inclinée.
