Definitions

  • a device of the above type is, for example, illustrated in the document No. FR 2707322 .
  • a typical technique of effraction in the case of locks of this type consists in forcing the cylinder lock out of the device. Fixing of the cylinder lock within the device is determined only by a pin that is inserted in the body of the cylinder lock. The resistance of the pin is limited both on account of the dimensions of the pin, which are difficult to increase substantially because cylinder locks have standardized dimensions and above all because the pin is subject principally to shear stress.
  • the problem that arises from this arrangement of the radial control member, in the resting condition of the lock either completely open or closed, consists in the fact that, when the cylinder lock is mounted within the casing, the radial control member can project laterally from the body of the cylinder lock either on one side or on the other indifferently, drawing along with it the ring gear with which it engages.
  • the mechanical transmission which follows the ring gear and actuates the lock-bolt element, will be in a position of advance or of delay in the travel of actuation.
  • the lock is devoid then of a precise and unique adjustment, and operation thereof becomes less fluid and more inconvenient for the user, who according to his own sensitivity must evaluate whether the lock device is completely open or completely closed.
  • the present invention proposes to overcome the drawbacks of the devices of the known art.
  • the subject of the invention is a safety-lock device according to Claim 1.
  • the movement of said driving member is designed to be transmitted to said driven member only after said members have reached a relative position of end-of-travel.
  • number 1 designates the safety-lock device.
  • This comprises a casing 2, within which a lock-bolt element 3 slides between a position of opening and a position of closing.
  • the lock-bolt element 3 is formed by locking elements, such as cylindrical bars 3a fixed to a plate 3b.
  • the plate 3b has guide slits 5 and a slit shaped so as to define a toothing 6.
  • the movement of the plate 3b is controlled by a mechanical transmission 7.
  • Said mechanical transmission 7 is constituted by a disk 8 and by a gear 9 ( Figures 4a, 4b).
  • the disk 8 Fixed on a face of the disk 8 are two axial pins 8a (not visible in Figures 4a, 4b and illustrated in Figure 3), designed to mesh with the toothing 6 of the plate 3b ( Figure 3).
  • the disk 8 moreover has a projecting portion 8b, designed to couple with the central hole 9b of the gear 9 ( Figure 4a).
  • the portion 8b has a substantially circular shape with a plane side 8b'.
  • the hole 9b has a corresponding circular shape, interrupted by two plane sides 9b', which are set at angles with respect to one another and define contrast surfaces co-operating with the surface 8b' to define two end positions in the relative rotation between the disk 8 and the gear 9.
  • the arrangement is in fact such that the circular portion of the hole 9b has an angular extension greater than that of the portion 8b of the disk 8. This creates a play (in the sense of possibility of relative rotation) between the disk 8 and the gear 9, the value of which is equal to the difference between said angular extensions.
  • the gear 9 meshes with a ring gear 10, the seat of which is made on a block 11 fixed to the casing 2 of the safety-lock device 1.
  • the ring gear 10 has a radial slit 10a having a width equal to the thickness of the bottom part of the body of the cylinder lock (not visible in the drawings).
  • the ring gear 10 surrounds the cylinder lock, which comprises, according to the conventional technique, a stator (not illustrated) fixed to the casing 2, and a rotor (not illustrated either), which can be actuated by means of a key (not illustrated) for driving a member 12 in rotation, from which a radial control element or ???"penna" 13 projects.
  • the radial control element 13 is set within the slit l0a of the ring gear 10 and, as may be seen in Figure 2, between the radial control member 13 and the side walls of the slit 10a there is present a play equal to the difference of width between the slit 10a and the radial member 13.
  • the stator of the cylinder lock is fixed within the casing 2 via a pin 14 that is inserted transversely in the bottom part of the body of the cylinder lock.
  • This pin 14 is carried by a plate 15, which can slide within the casing 2 between a position of engagement and a position of disengagement of the pin 14 within the body of the cylinder lock.
  • the plate 15 is controlled by a bar 16 accessible from outside. Since said blocking of the cylinder lock within the lock device is not considered sufficient for the purpose of safety, in the conditions of rest of the device, in a position of complete opening or closing, the radial control element 13 is set in such a way as to project laterally from the body of the cylinder lock.
  • the radial control element 13 is kept temporarily centred by keeping the key rotated with respect to its neutral position, after which the key is brought back into said neutral position, so that the element 13 projects laterally from the body of the cylinder lock.
  • Said projection can indifferently be situated on one side or on the other of the body, according to whether the body itself is inserted in the device starting from one of its ends or from the other.
  • the element 13 will not draw the ring gear 10 in rotation until it has come into contact with the right-hand side of the slit 10a.
  • the element 13 will draw in rotation the ring gear 10, which in turn will cause a corresponding rotation of the gear 9.
  • the rotation of the gear 9 will not be transmitted immediately to the disk 8, which carries the pins 8a meshing with the toothing 6 of the lock bolt, until the contrast surfaces 8b' and 9b' come into contact with one another.
  • the cylinder lock is mounted in such a way that, in the resting condition, the element 13 projects to the right (as viewed in the drawings), as illustrated for example in Figure 6, the small oscillation that the element 13 performs upon installation will cause a first initial rotation of the ring gear 10 in a counterclockwise direction. Said rotation brings about a corresponding rotation of the gear 9 such as to bring already into contact the contrast surfaces 8b', 9b'. Starting from said condition, a rotation of the key will immediately cause displacement of the lock bolt. As may be seen then, whether the element 13 is mounted projecting to the left ( Figure 8) or to the right ( Figure 6), the active movement of the lock bolt is brought about always starting from one and the same position of the actuation key.
  • the lock device is, at rest, in conditions of safety when the pins 8a of the disk 8 reside within the notches constituting the teeth of the toothing 6 of the plate 3b, i.e., when they are aligned in the direction of movement of the lock-bolt element 3. But the presence of the play enables the disk 8 to be rotated into a position in which one of the pins 8a is out of this position, in this way rendering reversible the travel of closing of the safety-lock device in the case where any thrust were to be exerted on the cylindrical bars 3a.
  • the radial element 13 At the end of the second idle travel, the radial element 13 reaches the position illustrated in Figure 8. As has been mentioned above, if the cylinder lock 12 is mounted in such a way that, at rest, the radial element 13 is located already in the position illustrated in Figure 6, the actuation of the key will immediately cause closing of the device, without any initial idle travel.
  • Illustrated in Figure 9 is the safety-lock device in which the chain of gears is in an intermediate position of the travel of actuation. It may be noted that the radial control member 13 acts as a tooth of the ring gear 10, and the transmission in the chain of gears continues fluidly in the travel of actuation.
  • the lock according to the invention is characterized in that it presents precise, reliable and convenient operation for the user, without on the other hand leading to a particularly complex structure.
  • the lock according to the invention can make use of gears all having their teeth with conformations and dimensions identical to one another.
  • a further advantageous characteristic of the preferred embodiment illustrated herein lies in the fact that the mechanical transmission that converts the rotation of the ring gear 10 into the movement of the lock bolt comprises a single gear 9 and the pair of pins 8a co-operating with the toothing 6.
