Definitions

  • the present invention refers to improvements in a rack and pinion system for activating lock cylinder units.
  • This invention enables the lock cylinder unit to be retained against rotating movement by a plurality of discs oscillating about its shaft and provided with a toothed section, a segmented area of each of them being housed in openings at corresponding points of a fixed sleeve of the cylinder unit.
  • the said discs are disposed in plates radial to the cylinder unit shaft, secured at their axial ends to circular supports.
  • the release position of the lock cylinder unit, so that it can rotate freely, is obtained by inserting, axially to the cylinder unit, the corresponding key provided with a plurality of racks disposed longitudinally at at least one of the faces of its polygonal profile, which racks are capable of meshing with the corresponding teeth of the discs; causing them to rotate to a maximim penetration position of the key at which segmented offsets of the discs coincide with the open- in6s of the fixed sleeve. At this position there are no means for retaining the cylinder unit against rotation.
  • Each of the discs is impelled by a spring which maintains it in an angular position fixed by a butt, in order to enable insertion of the key and so that the initial tooth of each of its racks impinges correctly on the first tooth of the disc, without causing any obstruction or blocking between teeth.
  • the wide range of loch cylinder units and corresponding keys is achieved by varying the number of teeth of at least one of the key racks, since this has a bearing on the final position adopted by the corresponding disc, and therefore its segmented offset, enabling the cylinder unit to rotate freely, should be placed at a different position.
  • the pitch of at least one of the rack and pinion gears must differ from that of the rest.
  • the teeth of at least one of the key racks can be disposed in a lineally offset position from those of the rest.
  • the discs provided with a toothed area are preferably placed at both sides of the radial plates, oscillating about a common shaft which passes through them, the said discs being angularly positioned so that the first tooth, on which the key impinges, is firmly positioned by the said butt, close to the shaft of the lock cylinder unit and coinciding therefore with that of the operating key.
  • the racks of the key will be positioned in pairs, their teeth ha v-ing the same or a different pitch, as well as also slightly offset, as already indicated.
  • the disc support plates are preferably arranged eccording to two perpendicular planes, so that their inner edges are close to the shaft, emerging from the discs, wherefore the key will adopt a general square section and will be provided with four longitudinal notches constituting the guiding means for the insertion thereof, since the longitudinal edges of the said support plates slide therealong.
  • the rack and pinion system for activating lock cylinder units is comprised of'a plurality of discs 1 provided at a partial area of their periphery with teeth 2, each one of which has a segmented offset defining a straight line 3 at a relative position with respect to the teeth 2, some discs differing fron others.
  • the discs 1 are preferably disposed in pairs and are rotatably supported at both sides of a plurality of support plates 4 disposed radially to the shaft of the lock cylinder unit, which plates are fixed at their ends 5 to axially-holed circular supports 6.
  • the support plates 4 are fixed to the circular supports 6 provided with the exial hole 7, the assembly being secured by screws 8 passing through holes 9 of a member 10 placed in a backed relation with the outer face of the inner circular support 6, and through corresponding holes 11 of said circular supports 6, the end of said screws 8 en- engaging in threaded holes of another end member 12 placed in a backed relation with the outermost circular support 6 and provided with the axial hole 13 for inserting the key 14.
  • each support plate 4 includes two discs 1 backed to their faces and oscillating about a common shaft 15 which passes through the support plate 4.
  • the shaft 15 is retained against axial movement since its ends are provided with annular slots 16 into which the end lugs 17 and 18 of one of the ends of abutting members 19 are introduced, the opposite end of which is secured to the support plate 4 by means of a pin 20.
  • Each abutting member 19 therefore has the dual purpose of, on the one hand, preventing the common shaft 15, for turning two discs 1, from emerging and, on the other hand, fixing the angular position of the teeth 2 of the disc 1,, when the pivot 21 emerging from the outer face of the disc 1, since it is aided by a spring 22, contacts its edge radially furthermost from the shaft of the cylinder unit.
  • each disc 1 has an area in the form of a circular segment 23 which emerges from the radially furthermost longitudinal edge 24 of the support plate 4.
  • the discs 1 present a circular segment 23, emerging from its support plate 4, this circular segment 23 being housed in the corresponding housing 28 made in the direction of the generators of a sleeve 29 of the cylinder unit frame, which remains fixed and therefore stationary with respect to the cylinder unit, thereby constituting the blocking means for the lock.
  • the housings 28 of the fixed sleeve 29 are formed of rectangular windows uniformly arranged on the circular periphery of the sleeve. In the embodiment shown in the figures, they are arranged in pairs, therefore forming, between each two consecutive pairs, a small stiffening partition 30 which insures the entire stable position and a maximum resistance against a possible fraudulent action due to the rotation of the cylinder unit.
  • Figure 4 also illustrates that the free edge 24 of the support plate 4 is positioned close to the inner surface of the sleeve 29, whereas its innermost edge is very close to the lock cylinder unit.
  • the profile has a polygonal shape, adapted to the number of support plates 4 of the cylinder unit shaft, said profile having a like number of notches 31 defining guiding means for the insertion of the key, since the innermost edge of the support plates 4 is housed in said notches 31 (see figures 1 and 4).
  • Each of the racks 26 disposed in the key 14 has a different number of teeth 25, so that, until the maximum insertion position of the key is reached, a different angular displacement will be produced in each one of the discs, or at least in some of them, wherefore the segmented offset 3 of each of the discs 1 is made at a relative position in accordance with the angular magnitude of the rotation.
  • the pitch of the rack and pinion gear of some of the discs 1 and their respective rack 26 can also vary, end further, although all the racks have the same pitch, the teeth of some of them can be offset from the teeth of others, enabling the number of possible combinations in the formation of the range of locks to be highly increased and preventing the same manufactured unit from being repeated.
  • the teeth of the racks 26 intervening in the rotation of the respective discs 1 are those positioned close to the end 32 for the insertion of the key, the said racks can depart from the same front surface 33 close to the widening 34 for securing the key, since this arrangement is not related to the functioning.
  • the fixed sleeve 29 of the lock cylinder unit is, in turn, covered with another steel sleeve 35 which conceals the housings 25 of the former, to prevent access to the discs 1 as Well as a fraudulent action.
