  • the lock 1 comprises a stator 3 within which a rotor 4 can rotate, such rotor being provided with a longitudinal slot 5 within which respective pins 6, 7 are substantially mutually opposite.
  • the slot 5 is adapted to accommodate the key 2, following the insertion thereof at a front of the lock 1.
  • the key 2 is provided with a hand-grip 2a and with an encoded shank 2b which is intended to be inserted into the slot 5 of the lock 1.
  • the key 2 comprises a seat 8 for accommodating a respective freely orientable lever 9: the lever 9 is pivoted within the seat 8 by way of a transverse peg 2c.
  • the orientable lever 9 is designed to actuate the pins 6 and 7 of the lock 1.
  • the freely orientable lever 9 of the key 2 conveniently comprises a substantially flattened free end 10 the thickness of which is less than that of the key 2. It can be seen from Figures 2 and 15 that such flattened free end 10 can be defined between two flat surfaces 11 and 12 which delimit an acute angle; such surfaces 11 and 12 are defined by straight generatrices parallel to the axis of the peg 2c for pivoting in the seat 8.
  • the free end 10 will advantageously be provided with at least one contoured protruding band 13 at one of the side edges of at least one of its faces, i.e. of one of the two flat surfaces 11 and 12.
  • the longitudinal slot 5 of the rotor 4 profitably will comprise, at its end portion, a pit 14 for the temporary accommodation of a respective contoured protruding band 13 of the key 2.
  • stator 2 and the rotor 3 will positively comprise radial holes 15 and 16 which define, in a configuration of mutual alignment, a conduit that faces the side surface of the longitudinal slot 5.
  • the conduit (which is constituted by the aligned holes 15 and 16) will conveniently accommodate elastic means 17, a respective counterpin 18 and a pin 19 which is adapted to abut against a side edge 20 of the key 2.
  • the pit 14 adapted for the temporary accommodation of a respective contoured protruding band 13 of the lever 9 can advantageously have an overall length that is less than the length of the lever 9 and a depth that is less than the height of the protruding band 13.
  • the dimensional parameters of the pit 14 can be better identified when the key 2 is completely inserted into the longitudinal slot 5, in relation to the specific parts thereof.
  • the pit 14 in fact, with respect to the key 2 when completely accommodated in the slot 5, presents an initial front 21 proximate to the pivoting axis of the lever 9 and a terminal front 22 facing toward the surface of the key 2 that is arranged upstream of the seat 8.
  • a central portion 23 of the pit 14 has constant depth, while the two mutually opposite end portions 24 and 25 are conveniently blended by way of curved surfaces to the longitudinal slot 5.
  • Such curved blending surfaces allow the lever 9 to slide on continuous surfaces, free from steps or sudden variations in dimensions or shape, thus ensuring that the access and extraction of the key 2 in the slot 5 take place without unwanted jamming or sticking.
  • the radial holes 15 and 16, which define the conduit which is adapted to accommodate the elastic means 17, the counterpin 18 and the pin 19, have a diameter of an extent proximate to the depth of the pit 14.
  • the radial hole 16 of the rotor 4 can conveniently comprise at least two segments 26, 26a of different diameter.
  • the presence of segments 26 and 26a and of zones 27 and 28 with differentiated diameters will cause the sticking of the pin 19 if forcing is attempted using a key 2 with the wrong coding on its side surface 20, thus preventing the lock 1 from being opened.
  • the pins 6 and 7 can conveniently present contoured fronts which are adapted for encoded abutment against respective complementary contoured portions that are present on at least one part of the lever 9 chosen from either the at least one contoured protruding band 13 and the flat face constituted by one of the flat surfaces 11 and 12 which delimit an acute angle.
  • This coding of the flat surfaces 11 and 12 or of the protruding bands 13 and of the fronts of the pins 6 and 7 will make it possible to further increase the security of the lock 1 against forcing.
  • the side edge 20 of the encoded shank 2b of the key 2 can conveniently comprise an encoded profile which is provided with at least one encoded recess 29 for the temporary accommodation of the head 30 of the pin 19, which will advantageously have a shape and dimensions that are complementary to those of the recess 29.
  • This encoded coupling of the head 30 with the respective recess 29 will also contribute to increasing the security of the lock 1 and of the key 2 with respect to the performance levels that can be obtained with locks A according to the prior art.
  • the lock 1 according to the invention is an innovative component by virtue of its implementation structure, even independently of its pairing with the key 2.
  • the key 2 is a highly innovative component and extremely versatile in that it can also be used in conventional locks A.
  • the key 2 advantageously has many parts that are similar to those of conventional keys B: such characteristics render the new key 2 very versatile in that it will work on conventional locks A as well. This versatility is particularly useful in cases where only some of the locks are replaced in a building administered using coordinated encodings: in this case, only a few authorized persons will need to have a passkey 2 that can open all the locks 1 and A that are present.
  • the protruding band 13 is contoured to at least partially enter the slot for accommodating the pin 6, thus making it possible to minimize the dimensions of the recess 14.
  • the present invention solves the drawbacks mentioned above, by providing a lock 1 and related key 2 that offer high security against forcing.
  • the lock 1 and the related key 2 according to the invention allow the adoption of a high number of encoding pins.
  • lock 1 and the related key 2 according to the invention allow the use of any surface of the key 2 as an encoded surface.
  • the key 2 according to the invention is compatible with locks A according to the prior art and therefore it can be integrated in buildings where there are conventional locks A and locks 1 according to the invention, including as a passkey 2.
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.

L'encoche (5) est conçue pour l'insertion d'une clé (2) pourvue d'un siège (8) destiné à la réception d'un levier respectif (9) librement orientable et conçu pour actionner les broches (6, 7). Le levier (9) librement orientable de la clé (2) comprend une extrémité libre (10) sensiblement aplatie dont l'épaisseur est inférieure à celle de la clé (2) : l'extrémité libre (10) est pourvue d'au moins une bande (13) saillante profilée au niveau de l'un des bords latéraux d'au moins l'une de ses faces. L'encoche longitudinale (5) du rotor (4) comprend, au niveau de sa partie d'extrémité, un creux (14) pour le logement temporaire d'une bande (13) saillante profilée respective de la clé (2). Le stator (2) et le rotor (3) comprennent des trous radiaux (15, 16) qui définissent, dans une configuration d'alignement mutuel, un conduit qui fait face à la surface latérale de la fente longitudinale (5) : le conduit loge des moyens élastiques (17), une contre-broche (18) respective, et une broche (19) qui est conçue pour venir en butée contre un bord (20) latéral de la clé (2).
