Definitions

  • the present invention relates to a covering plate for locks, such as for example a plaque or a washer, suitable for being associated to a lock for partly- covering the same .
  • the object of the present invention is to solve the disadvantages mentioned with reference to the prior art.
  • figure 1 shows a perspective view of a plate according to an embodiment of the present invention, said plate comprising an associable key;
  • figure 2 shows a perspective view of the plate of figure 1 wherein the key has been omitted;
  • figure 3 shows a perspective view of a plate according to a further embodiment of the present invention
  • figures 4-7 show perspective views of plates according to further embodiments of the present invention.
  • reference numeral 4 globally denotes a covering plate for locks, such as for example a plaque 8 or a washer 12, suitable for being associated to a lock for partly covering the same.
  • Plate 4 comprises an inlet hole 16 for the passage of a key 20 suitable for inserting into the lock; key 20 for example is of the type comprising a rod 24 and a blade 28.
  • the inlet hole 16 of plate 4 in an assembly configuration, is aligned relative to a keyhole of the lock suitable for receiving said key 20.
  • plate 4 comprises guiding means 32 for inserting key 20, arranged between plate 4 and the lock keyhole, and suitable for guiding the insertion of key 20 so as to centre blade 28 of key 20 relative to the keyhole of the associable lock.
  • the guiding means 32 are arranged externally relative to the inlet hole 16 so as to allow the insertion of key 20 through hole 16 itself and prevent the rotation of blade 28 relative to rod 24 until blade 28 is not at least partly inserted into the keyhole .
  • the guiding means 32 comprise at least a pin 36 that projects from plate 4 towards the associable lock so as to interfere with the rotation of blade 28 of key 20 relative to rod 24 until said blade 28 is not at least partly inserted into the keyhole.
  • the guiding means comprise at least a pair of pins 36 arranged symmetrically relative to the inlet hole 16, so as to prevent rotations of blade 28 in both directions of rotation.
  • the guiding means 32 are at least partly counter-shaped relative to key 20 so that during the insertion of key 20 in the inlet hole 16 of plate 4, the rotation of blade 28 of key 20 is prevented until said blade 28 is not at least partly inserted into the keyhole .
  • the guiding means 32 comprise at least one partition 40 suitable for guiding the insertion thereof into the keyhole, partition 40 interfering with the rotation of blade 28 relative to rod 24, at least until blade 28 is not partly inserted into the keyhole.
  • the guiding means 32 comprise at least a pair of partitions 40 (figure 5) arranged symmetrically relative to the inlet hole 16, so as to prevent rotations of blade 28 in both directions of rotation.

  • the hollow body 44 comprises a cylindrical portion 48 substantially counter-shaped relative to rod 24 of key 20 and a notch 52 suitable for allowing the passage of blade 28 of key 20 substantially preventing the rotation thereof.
  • the hollow body 44 is truncated-cone towards the associable keyhole, so as to form a seat for the insertion of key 20.
  • the guiding means 32 are integrally associated to plate 4 at an inner wall 56 of plate 4, directly facing the keyhole of the associable lock.
  • the guiding means 32 are associated to plate 4 by gluing and/or welding or even by threaded connecting means .
  • plate 4 comprises a plaque 60, associable to the lock, and provided with the guiding means 32, plaque 60 being interposed between the lock keyhole and the covering plate 4.
  • the guiding means 32 are made integral with plaque 60, or they may be associated to plaque 60 by gluing and/or welding, or by threaded connecting means.
  • Plaque 60 may be provided with fixing holes 64 for anchoring plague 60 itself, for example to the lock.
  • Plate 4 may be associated to cover plaque 60 by forced and/or snap-wise coupling.
  • plate 4 comprises a plaque 8 that turnably seats an actuating handle for opening and/or closing the shutter or door the lock is associated to.
  • the key insertion is very quick and easy, even in poor visibility conditions .
  • the plate according to the present invention does not change the overall external appearance of the lock and is very inexpensive to make.
  • a man skilled in the art may make several changes and adjustments to the plates described above in order to meet specific and incidental needs, all falling within the scope of protection defined in the following claims.

Abstract

L'invention porte sur une plaque de recouvrement (4) pour serrures, telle que, par exemple, une plaque (8) ou une rondelle (12), appropriée pour être associée à une serrure afin de recouvrir partiellement celle-ci. La plaque (4) comprend un trou d'entrée (16) pour le passage d'une clé (20) qui est alignée par rapport à un logement de clé de la serrure. Avantageusement, la plaque (4) comprend des moyens de guidage (32) pour l'introduction de la clé (20), agencés entre la plaque (4) et le logement de clé de serrure, et appropriés pour guider l'introduction de la clé (20) de façon à centrer le corps (28) de la clé (20) par rapport au logement de clé de la serrure associée.
