Definitions

  • a lock comprising a rotor and a stator, the rotor being rotatable in the stator by means of a key from a first position to a second position
  • the improvement comprising means defining a first abutment associated with the rotor for rotation therewith, means defining a second abutment mounted in the lock nonrotationally relative to the axis of the rotor, the second abutment being in such engagement with the first abutment as to block rotation of the rotor from the first position to the second position when the rotor is in the first position, the manually operable means for shifting the second abutment out of the blocking engagement with the first abutment to permit rotation of the rotor from the first position to the second position.
  • these apparatuses are operated by the rotation of a lock cylinder operated by a key having a toothing combination unique to the lock cylinder of the vehicle in question. It is particularly for this type of antitheft device that the invention is intended.
  • the lock cylinder employed to lock one of the aforementioned elements is the one which also serves to operate and lock the ignition switch.
  • the present invention preferably provides a device which completely prevents the withdrawal of the key when the ignition is switched off until the driver has carried out a supplementary operation which requires, apart from the grasping of the key with two fingers, an effort exerted perhaps by another finger of the hand. Moreover, this effort preferably takes place in a direction contrary to that of the pull which tends to withdraw the key; this effort, because unaccustomed, is very effective as a safety measure.
  • the effort in question preferably is a thrust upon a mechanism provided for this purpose and which responds only to a thrust.
  • FIG. 1 is a side elevation of an antitheft device with the bolt engaged in a striking plate in the form of a ring fixed to the essential element, for example the steering column, the striking plate being shown in a section taken on a vertical plane passing through the axis of stator 1, the key being in the withdrawal position
  • FIG. 2 is a front elevation of the same antitheft device with the key in the same position but with the striking plate not i]- lustrated;
  • FIGS. 3 and 4 correspond to FIGS. 1 and 2, respectively, but with the key in the position (I) corresponding to the garage" or parking" position;
  • FIG. 5 is on a larger scale in partial vertical axial section the antitheft device according to FIGS. 1 to 4 illustrating in detail one of the embodiments of the mechanism according to the invention, the key being in position (I) optionally permitting withdrawal of the key;
  • FIG. 6 is a partial section taken on section line CC of FIG.
  • FIGS. 7 and 8 correspond to FIGS. 5 and 6, respectively, but with cylinder 2 in position (0) and the key withdrawn, D- D being a section line corresponding to C-C;
  • FIGS. 9 to 12 are another embodiment of the invention in views and key positions corresponding to FIGS. 5 to 8, respectively, E-E and F --F being section lines corresponding to C-C.
  • FIG. 1 key is seen in the position (0), for which position and each of the other positions markings are provided on the front face 1a of stator 1, ready to be withdrawn from rotor or cylinder 2 which together with the stator 1 comprises a lock mounted in a sleeve 3.
  • a lock mounted in a sleeve 3.
  • the mechanism seen in section in FIGS. 5 to 8 is composed of a base I2 attached to the cylinder 2 of the antitheft device, the cylinder 2 bearing at the surface 13 on the base 12 and consequently rotating the base 12 with the cylinder 2, when the latter is rotated by means of the key 10 and the movement of the base 12 and consequently the cylinder 2 is not stopped by the device which will be described.
  • the base 12 is provided with a raised portion 14 having a flange 15 below which is defined a recess 16 in the periphery of the base 12.
  • a hook 24 formed on the lower end of the noncylindrical stud 17, the stud 17 being biased upward by the action of a spring 21 the lower end of which bears upon a shoulder 25 of the stator and the upper end of which bears upon a stop provided in any manner at 20 on the body of the stud 17.
  • a cotter 11 is fixed in the stator in engagement with a slot 18 in the stud.
  • the hook 24 has a notch 23, dimensioned to permit the passage therethrough of the flange l5, and a tenon 22 of sufficient width at the bottom of the notch 23 to provide mechanical strength and wear-resistance for the engagement with the flange 15.
  • lock construction is such as to permit withdrawal of the key in position (I) or by known mechanism to prevent withdrawal of the key in that position, though the former is the more common arrangement.
  • actuation of the safety device according to the invention is necessary to rotate the cylinder to the (0) position, the only position effecting locking by at least partial withdrawal of the key.
  • FIGS. 9 to 12 illustrate another mechanical embodiment of the invention, in which:
  • the stud 7 is of simpler construction; it acts upon a leaf spring 5 the end 26 of which, when the cylinder is in the (I) position, abuts against a shoulder 27 protruding from the base 6. A thrust exerted upon the exposed end of the stud 7 effects lateral moving aside of the spring 5 by the other end of the stud 7 which moving aside permits the shoulder 27 to pass in order to effect rotation of the cylinder to the (0) position by means of the key, whereupon there may be effected the withdrawal of the latter and, consequently, the locking of the antitheft device.
  • the dimensions of the raised portion of the rotor base are always determined by the phases or the kinematic program imposed for the antitheft device in its mechanical and electrical functions for operating the various main and auxiliary, running and starting circuits. Furthermore, neither the introduction of the key nor the rotation of the cylinder in the active direction, i.e., from the (0) to the (I) to the (II) to the (III) position, is prevented by the devices as described. Conventionally, the (III) position of the cylinder closes the starter circuit and when the key is released by the driver once the engine is firing regularly, the cylinder rotates to the (ll) position in which the running circuits are closed.
  • a lock of the type having an elongated rotor and a stator, both being substantially coextensive axially and the rotor extending in the stator from an exposed end to an inner end of the rotor, for rotation by a key insertable and removable through the exposed end, by the user's engaging the key head with his fingers
  • the improvement which comprises: a spring in the stator for selectively permitting and preventing said rotation of the rotor; an abutment mounted on the inner end of the rotor for rotation therewith, subject to engagement with said spring and for consequent blocking of further rotation of the rotor; and rod means axially displaceable in the stator, adjacent the periphery of the key head engaged by the user, and having one end protruding from the exposed end; the other end of the rod means and the spring being so constructed and arranged that, when the protruding end of the rod means is manually depressed the other end of the rod means urges the spring out of the normal position thereof, which blocks said further rotation, whereby user
  • said spring is a leaf spring extending through the stator from adjacent the exposed end to the inner end of the rotor.
  • a lock according to claim I for locking a control element, said lock further including a bolt, and means for engaging the bolt with the control element when the rotor is in one of the rotary positions thereof, and for disengaging the bolt from the control element in at least one other rotary position of the rotor.
  • a lock according to claim 5 in which the means for engaging and disengaging the bolt with the control element is so constructed and arranged as to effect such engaging only upon partial withdrawal of the key from the lock.
