Definitions

  • the present invention relates to a lock for a double leaf door, which is also adapted to function on double-leaf doors provided with emergency opening devices (handles or emergency door bars).
  • the secondary leaf can be locked manually (with adapted locking couplings that are generally mounted on the ceiling and floor) or it can be, like the main leaf, opened by way of a respective handle (in such case the handle will be designed to retract the locking couplings, if present). Obviously the handle of the secondary leaf will not be operational when the main leaf is closed (in particular if it is locked) in order to prevent forced entry.
  • the spring latch and the sliding latch (even when the latter is completely extracted for secure closure) must be completely retracted with a single movement of the handle (or of the panic bar): a person fleeing (from a fire or other risk situations) must be able to exit from the spaces delimited by the door simply by pushing the handle (or the panic bar).
  • the safety lock is provided with a pusher that acts on a protruding pin of the lock, freeing the reentry of the sliding latch and of the spring latch: at this point the action of a pusher (in general the same one) on the sliding latch causes its retraction and, thanks to adapted internal lever mechanisms, also causes the consequent retraction of the spring latch, and thus the opening of the main leaf as well.
  • Such pin according to a particularly efficient embodiment devised by the applicant and disclosed in Italian patent ITO 1263073, is installed at the end front wall of the sliding latch: this embodiment ensures that it is not accessible (for the purposes of forcing entry) and thus makes it possible to maintain a high level of security for the lock that comprises it.
  • an object of the invention is to provide a lock for leaf doors which does not necessarily require the presence of delicate components, such as springs and elastic means.
  • FIG. 1 is an exploded perspective view of a lock for leaf doors according to the invention
  • FIG. 1 is a cross-sectional side view, taken along a central vertical plane, of the lock in Figure 1.
  • the spring latch 6 and the sliding latch 7 are functionally associated with the handle and with the cylinder 3.
  • the lock 1 further comprises a tab 9 that protrudes from the sliding latch 7.
  • the at least one sliding latch 7 is locked in the extracted configuration when the tab 9 is protruding; the sliding latch 7 on the other hand is free to retract, when it is subjected to an external force that forces its retraction, only when the tab 9 is retracted inside the sliding latch 7 following a respective external action.
  • the sliding latch 7 comprises an internal cavity 7a for the slideable accommodation of a lever 10 that is constituted, at a first end thereof, by the tab 9, and, at a second end thereof, by a tooth 1 1.
  • a second arm 14 of the cam 13 is resting against a protrusion 15 of a movement element 16 intended for the translation of the sliding latch 7 (and also of the spring latch 6).
  • the translation of the movement element 16 causes the egress of the projection 18 from the offset recess 20 of the groove 19.
  • Such egress causes the movement of the projection 18 in the inclined portion 20, with consequent free retraction of the sliding latch 7, and of the spring latch 6 which is mechanically coupled thereto, following an external force applied to the sliding latch.
  • the force applied to the tab 9 (and thus to all of the lever 10) and the force applied to the sliding latch 7 can thus be constituted by the action of the panic bar installed on the secondary leaf onto which the main leaf, on which the lock 1 is installed, is closed.
  • the lever 10 is flattened and substantially rectangular.
  • the first end of the lever 10, which comprises the tab 9, is not as high as the remaining part of the lever 10 and the second end comprises the tooth 1 1 that protrudes along an inclined direction with respect to the longitudinal direction of the lever 10.
  • the tooth 11 has a rounded end shape for continuous abutment on the arm 12 of the cam 13.
  • the cam 13 can effectively have two walls that are mutually opposite and mutually inclined so as to define an angle.
  • the cam can thus have a substantially triangular shape, even though the possibility is not excluded of having different shapes that in any case allow the two walls to be mutually opposite and incident.
  • Such walls are constituted by the outer sides of the first arm 12 and of the second arm 14.
  • the movement element 16 comprises a first laminar band 22 that is provided, proximate to its end face 23, with the protrusion 15, and, at a central portion thereof, with a first toothing 24 that is functionally associated with a gear 25 for controlling the spring latch 6.
  • the gear 25 can preferably be constituted by a circular sector that is toothed at one of its ends and pivoted to the boxlike body at an intermediate portion thereof, and having the opposite end with respect to the toothed end associated with the rotating bushing 4 (which is intended to accommodate the handle): a rotation of the gear 25 thus causes a rotation of the bushing 4 (similar to the rotation that occurs by rotating the handle) with consequent retraction of the spring latch 6.
  • the movement element 16 can further positively comprise a second laminar band 26, facing toward the first band 22, provided with a second toothing 27 that is functionally associated with a toothed wheel 28 that is coupled to a toothed bar 29 for controlling the spring latch 6.
  • the toothed bar 29 is associated with the rotating bushing 4 (which is designed to accommodate the handle): a rotation of the toothed wheel 28 causes a translation of the bar 29 which is followed by a rotation of the bushing 4 (similar to the rotation that occurs by rotating the handle) with consequent retraction of the spring latch 6.
  • the toothed wheel 28 also comprises, as a consequence, a cavity 31 of shape and dimensions that are complementary to those of the bump 30 for the stable accommodation thereof in the closed configuration of the leaf, i.e. when the sliding latch 7 and the spring latch 6 are protruding from the boxlike body 2 and the tab 9 is protruding from the sliding latch 7.
  • the projection 18 is arranged on a portion of one of the bands 22 and 26 which faces and is proximate to the groove 19 of the sliding latch 7.
  • the projection 18 is arranged on the inner face of the second laminar band 26, with reference to the embodiment shown by way of example in the accompanying figures.
  • the offset recess 21 of the groove 19 is preferably constituted by an indentation having a direction perpendicular to the direction of translation of the sliding latch 7.
  • the locks fitted to main leaves and to secondary leaves comprise door bolts that are intended to engage respective seats of the jamb (or of the masonry doorway) which are arranged above and below the leaf proper (when this is in the closed configuration).
  • the movement element 16 will be coupled, with one of its ends 32, to a first door bolt that selectively protrudes from the lower end of the installation leaf.
  • the toothed bar 29, for controlling the spring latch 6, can be coupled, with an end 33 thereof, to a second door bolt that selectively protrudes from the upper end of the installation leaf.
  • the present invention solves the above mentioned problems, by providing a lock 1 for leaf doors which is mechanically simple and easy to actuate.
  • the lock 1 does not necessarily require the presence of delicate components, such as springs and elastic means: in fact it takes advantage of the weight of the various components (and of the influence of the force of gravity) in order to ensure the appropriate certainty of closure (in conditions of standard use) and the certain and immediate opening in the event of actuation of the panic bar in order to allow a rapid and easy flight.
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.

Abstract

La présente invention concerne une serrure (1) pour portes à battant qui comprend un corps en forme de boîte (2) destiné à contenir un cylindre de mouvement (3) associé à une clé d'actionnement respective, une douille tournante (4) associée à une poignée, des mécanismes de levier adaptés (5) destinés à la translation d'au moins un loquet à ressort (6) et d'au moins un loquet coulissant (7), qui sont associés fonctionnellement à la poignée et au cylindre (3), et une languette (9) faisant saillie à partir du loquet coulissant (7). Ledit loquet coulissant (7) est bloqué dans la configuration d'extraction lorsque la languette (9) est en saillie, et il est libre de se rétracter s'il est soumis à une force externe, lorsque la languette (9) est rétractée à l'intérieur du loquet coulissant (7) à la suite d'une action externe respective. Le loquet coulissant (7) comprend une cavité interne pour le logement coulissant d'un levier (10) qui est constitué, au niveau d'une première extrémité de celui-ci, de la languette (9), et, au niveau d'une seconde extrémité de celui-ci, d'une dent (11) ; la dent (11) est orientée vers un bras (12) d'une came (13) qui pivote vers le corps en forme de boîte (2). Un second bras (14) de la came (13) repose contre une saillie (15) d'un élément (16) pour le déplacement du loquet coulissant (7). L'élément de mouvement (16) comprend une protubérance (18) qui peut coulisser à l'intérieur d'une rainure (19) du loquet coulissant (7). La rainure (19) est pourvue d'une partie inclinée (20) et d'un évidement décalé (21) destiné au logement de la protubérance (18) dans la configuration verrouillée du loquet coulissant (7). La rétraction de la languette (9) provoque l'enfoncement de la dent (11) sur le bras (12), avec, en conséquence, la rotation de la came (13) et le soulèvement du bras (14) : ceci provoque la translation de l'élément de mouvement (16) au moyen de la saillie (15). Ladite translation provoque la sortie de la protubérance (18) à partir de l'évidement décalé (20) de la rainure (19) avec, en conséquence, la rétraction libre du loquet coulissant (7), et du loquet à ressort (6) qui est accouplé mécaniquement à celui-ci, à la suite de l'application à celui-ci d'une force externe.
