Definitions

  • the present invention relates to a precision key for locks, of the type which are blade-shaped and which at their end comprise a longitudinal beam which is installed in a window of the key and which, in this window, has the ability to perform two combined and limited rotational movements, one of transverse rotation in a plane perpendicular to the blade, the other of lateral rotation in the plane of the blade.
  • the function of this longitudinal pendulum is to intervene in the establishment of a condition of opening key prior and additional to that of the conventional games of combination pins, by imposing a concrete position of the pendulum for one or more Auxiliary combination pins may act.
  • a double stop is established for the transverse rotation: in the rear end with respect to the tip of the key, a central frontal projection is formed between the lateral planes and which plays with each of the flanges which are the extension of the largest faces of the flat blade and which penetrate into the rear edge of the window relative to the tip of the key in which the pendulum acts; and in the front end with respect to the end of the key, it forms two transverse cuts made in the material of the flat blade, housing between them a fine transverse cylindrical key which is of a diameter much smaller than that of the axis of articulation of the balance.
  • this type of balance acts on a window which has a shape of circular sector which in its narrow front end begins to widen behind the axis around which the pendulum turns.
  • the stop of the lateral rotation is arranged between the flat lateral flanks of the balance and the radial walls, also flat, of the sectorial window; so that this form of abutment can be achieved in this way, great precision is also necessary if the force of the abutment will be exerted on its own axis of articulation as well as on the cylindrical key mentioned above.
  • this invention recommends a precision key for locks, with a blade which, at its tip, comprises a longitudinal balance capable of two combined and limited rotational movements, one of transverse rotation, in a plane perpendicular to the blade, the other, lateral rotation, in the plane of the blade.
  • the invention consists in that this longitudinal balance, in its front end, or foot of a pendulum, forms a deep doubly arched cavity which is parallel to the axis of equilibrium of the longitudinal balance and which is concave in profile in the longitudinal direction of the blade and of convex profile in the direction perpendicular to that prior, the cavity doubly arcuate being capable of receiving within it a transverse rotation stop which is integrated in one piece or added to the blade and whose operational section is of the order of that of this equilibrium axis; in that, in its rear end, or balance head, the longitudinal beam forms a bulge similar to a sphere; in that, in its bulge starting section, this rocker head is connected with the rocker foot by means of flat and parallel flanks between them which are located between two convergent walls of a window which is formed in the blade to the rotating play of the longitudinal balance, these convergent walls being extended to the front end of the window
  • the almost spherical balance head is rounded at its upper and lower faces which are oriented towards the largest faces of the blade and, in its flanks oriented towards the smallest faces of the blade, this rocker head has flat faces which, with respect to the lateral rotation of the longitudinal beam, are remote from the respective facets of the blade.
  • the window with an amplitude greater than that existing between the flat and parallel flanks and the converging walls, and less than that existing between the doubly-arcuate cavity and the transverse rotation stop.
  • the balance head is released from other functions that are not its main mission, that of allowing in the widest and most effective way possible to establish an auxiliary and preliminary key that allows the opening with the key to the main game of conventional pins.
  • An alternative embodiment of the invention consists in that the transverse rotation stop is added and consists of a pin of the same operating diameter as the axis of equilibrium of the longitudinal balance; that is, the equilibrium axis and the transverse rotation stop may be the same piece, which allows economy.
  • transverse rotation abutment is entire and consists of a rib of operational cross-section equivalent to that of the equilibrium axis and cut into the blade itself. such that it has a convex profile in the longitudinal direction of the blade and a concave profile in the direction perpendicular thereto.
  • a blade (1) which in its tip comprises a longitudinal beam (2) capable of two combined and limited rotational movements, one of transverse rotation in a plane perpendicular to the blade (1), the other of lateral rotation in the plane of the blade (1).
  • the object of the invention is that said longitudinal beam (2), in its front end, or rocker foot (2a), forms a deep doubly arched cavity (2b) which is parallel to the axis of balanced (3) of the longitudinal beam (2) and which is of concave profile in the longitudinal direction of the blade (1) and of convex profile in the direction perpendicular thereto, the doubly-arcuate cavity (2b) being capable of receiving a transverse rotation abutment (4) which is integrated or added to the blade (1) and whose operating section is of the order of that of said equilibrium axis (3); in that said longitudinal beam (2), in its rear end, or rocker head (2c), forms a bulge in a manner similar to a sphere, and this rocker head (2c), in its section of the beginning of the bulge, is connected with the rocker foot (2a) by means of flat and parallel flanks (2d) between them which
  • the almost spherical balance head (2c) is rounded at its upper and lower faces which are oriented towards the largest faces of the blade (1) and, on its flanks oriented towards the smallest faces of the blade (1), this rocker head (2c) has two flat faces (2e) which, with respect to the lateral rotation of the longitudinal beam (2), are spaced apart from the respective facets (5b) of the window (5) in such a way that both greater than that existing between the flat and parallel flanks (2d) and the converging walls (5a), and less than that existing between the doubly arcuate cavity (2b) and the transverse rotation stop (4).
  • the couples of Figures 10-11 and 12-13 represent the abutment positions of the lateral and transverse rotations for a variant embodiment of the invention; and the pairs of Figures16-17 and 18-19 represent another variant embodiment.
  • the functional advantages of the bulge of the balance head (2c) can be assessed by observing the figure 8 , where the longitudinal balance (2) of the blade (1) is placed between a fixed lug (6) and a first auxiliary auxiliary lug (7) which is almost diametrically opposite to the latter; at the same time a second auxiliary auxiliary lug (8) abuts on a point of the large surface area which remains in said balance head (2c), which provides a greater margin of tolerance in the position of this last and even the possibility of using more auxiliary pins than those shown on this figure 8 .
  • the Figures 9 to 14 represent an alternative embodiment of the invention, consisting in that the transverse rotation stop (4) consists of a pin (4a) which is of the same operating diameter as that of the equilibrium axis (3) of the longitudinal balance (2).
  • the figure 14 represents the assembly of the rocker arm (2) by means of two parts identical to each other and mounted on each side of the edge of the blade (1); one of the pieces is the equilibrium axis (3) and the other is the pin (4a) which serves as a transverse rotation stop function (4).
  • the Figures 10 and 11 show the stop positions of the balance in their lateral rotation.
  • the Figures 12 and 13 relate to the transverse rotation.
  • FIG. 15 to 20 Another variant embodiment is that represented on the Figures 15 to 20 , and also used for the figure 1 . It consists in that the transverse rotation stop (4) is integral and consists of a rib (4b) of operational cross section equivalent to that of the equilibrium axis (3) and that it is cut in the blade itself (1) so that it has a convex profile in the longitudinal direction of the blade (1) and a concave profile in the direction perpendicular thereto.
  • the figure 20 represents the assembly of the balance (2) by means of a single piece, the equilibrium axis (3), since the transverse rotation stop (4) is materialized by the rib (4b) which is machined integrally in the blade (1).
  • the Figures 16 and 17 show the stop positions of the balance in their lateral rotation.
  • the Figures 18 and 19 relate to the transverse rotation.
  • the blade (1) of the key is a type of flat blade.
  • the blade (1) is a type of blade with a combination toothing at its edge.
