I971 SHEET 8 OF 8 ATENTEU JUL 21 1911 SHEET 7 [IF 8 PATENTEU JUL2 71971 SHEET 8 OF 8 SAFETY MECHANISM FOR ANTIITI-IEFT ARRANGEMENTS APPLICABLE TO AUTOMOBILES My invention has for its object a safety mechanism for antitheft arrangements applicable to automobiles.
  • This mechanism is of the type including a safety lock of which the stator or stationary section is secured within a body or casing while the rotor or rotary central section is actuable by a key.
  • the rotor is rigid with or carries the safety lock in a manner such as to control the movements of a bolt which after the removal of the key prevents the operation of one of the main parts of a vehicle such as the steering column.
  • the rotor is furthermore generally designed so as to control in synchronism with the lock the operation of a switch controlling one or more electric circuits chiefly the ignition circuit and the starter controlling circuit.
  • the mechanism according to my invention includes chiefly a driving member angularly and axially rigid with the key actuated lock rotor, said driving member being rigid with a rod aligned with the rotor axis coinciding with the axis of the whole arrangement and extending freely through a bolt adapted to slide transversely within the body of the arrangement the free end of said rod cooperating in any suitable manner with a rotary switch of any known type; said driving member carries furthermore two suitably outlined projecting tenons adapted to cooperate with corresponding slopes and shaped surfaces on the bolt during the different operative stages while elastic means exert a pressure on the bolt so as to urge during predetermined operative stages its bolting end outwardly of the body of the lock.
  • the key extends beyond the driving member so as to cooperate with a pivoting block subjected to the thrust of elastic returning means, said block forming with the key a stop holding the bolt against progression for one predetermined pivotal direction while it is adapted to collapse through a pivotal movement in the opposite direction.
  • a spring acting against torsion is fitted in the driving member and is tensioned annularly during the last stage of the angular shifting of the rotor and of the driving member controlling the operation of the starter this being provided through abutment between the outer radial end of said spring and a stud or the like stationary stop rigid with the stator.
  • the thrust exerted by said spring against the bolt is compensated during said angular motion by a shaped tenon or projection engaging a slope on the bolt.
  • Two main elastic systems arranged independently ensure in fact respectively an elastic thrust urging the bolt into a locking position for one of said systems and an elastic thrust returning the key back into its circuit-closing position for the other system.
  • a still further feature of my invention consists in safety means preventing the actuation twice in sequence of the starter, this being obtained by a cam-shaped washer fitted just beyond the driving member between the latter and the bolt, said cam-shaped member allowing the tenons on the driving member to pass through it, as also the end of the key.
  • Said washer is partly free during a fraction of its angular movements with reference to said driving member, the peripheral outline of the cam-shaped washer being such that it prevents during the first actuation of the starter an elastic push-rod fitted inside the body of the arrangement from entering a notch forming a stop at the periphery of the driving member said push rod dropping then inside the said notch while an operation in a direction opposed to that providing said actuation remains necessary before the actuation of the starter can be repeated.
  • the execution of the arrangement may be simplified and the assembling and operation of some parts of the mechanism may be improved while certain advantages may be underlined.
  • FIG. 1 illustrates diagrammatically a steering column for an automobile provided with my improved antitheft arrangement.
  • FIG. 2 to 4 are respectively elevational, plan partly sectional and end views of my improved arrangement.
  • FIG. 5 is an axial cross-sectional view through line 5-5 of FIG. 3
  • FIG. 6 is a partly sectional plan view, the section line being shown at 6-6 in FIG. 5
  • FIG. 7 is a cross section through line 7-7 of FIG. 5
  • FIGS. 8 and 9 are cross sections through lines 8-8 of FIG. 6 and 9-9 of FIG. 5 respectively.
  • FIGS. 10 and 11 illustrate the assembly of the torsion spring ensuring the return of the key into the position corresponding to normal running conditions of the automobile after actuation of the starter.
  • FIG. 12 is an exploded perspective view showing the different parts of the mechanism accordling to the invention.
  • FIGS. 13 to 21 illustrate successive operative stages of the mechanism
  • FIG. 22 is an exploded perspective view of the different parts of the safety means controlling the starter.
  • FIGS. 23 to 27 are all similar views showing in association with the cam-shaped washer and in cross section through line 23-23 of FIG. 22 the different stages of the operation of the safety means controlling the starter
  • FIG. 28 is a general elevational, partly sectional view of the safety means incorporated with a modification of the antitheft arrangement, the switch associated with which being of any known type is consequently not sectionalized in said figure.
  • FIG. 29 is a corresponding plan view, partly sectional through line 29-29 of FIG. 28.
  • FIG. 30 is an also exploded perspective view showing in their relative axially aligned position, the driving member and cam-shaped washer.
  • FIG. 31 is also a perspective view showing on the one hand the body of the lock partly sectionalized and on the other hand the bolt and surface of the driving member cooperating with said bolt.
  • FIGS. 32 to 35 are all similar views constituted by cross sections through line 32-32 of FIG. 28 and illustrating the different operative stages of the safety means controlling the starter.
  • FIG. 36 is a cross section through line 36-36 of FIG. 28 showing the key returned into an angular safety position with the rotor, the driving member and the bolt, after the key has been brought into its locking position and released without being removed.
  • the body or casing l of the lock is fitted as illustrated in FIG. 1 in a casing or the like support S drawn in dot and dash lines so as to cooperate with the steering column of an automobile.
  • a switch C of any suitable type is located beyond the body 1 so as to open and close in synchronism with the operation of the bolt one or more essential electric circuits carried by the vehicle. It is not necessary to describe said switch, which is in- I dependent of the arrangement forming, the object of my invention.
  • the body 1 is provided with an axial bore la and a transverse housing lb which latter opens at both ends into the periphery of the body I.
  • the bore 1a encloses a safety lock of a well-known type including a stator 2 forming an outer cage and secured to the body 1 by a pin 3 or the like preventing any dismantling.
  • the rotor 2a or central rotary section of the lock cooperates with a key 4. The latter may be removed from the rotor only for two positions assumed by it, to wit a first steering-locking position and an intermediate parking position for which the steering means are not locked, but for which the ignition circuit cannot be closed.
  • the end of the rotor inside the body I is angularly and axially rigid with a driving member 5.
  • the latter is rigid with an axial rod 5a and two lateral tenons 5b and 5c.
  • the tenon 5c extends laterally so as to form a boss or nose-shaped sector 50' the thickness of which is smaller than the length of said tenon 5c.
  • the axial rod 5a extends in alignment with the rotor axis which coincides with the axis of the whole arrangement.
  • the free end of the rod 5a is designed in any suitable manner so as to cooperate with the rotary movable section of a rotary switch. Such a cooperation is an easy matte and may be executed without any further technical information. It should be remarked that the axial location of the rod controlling the switch allows resorting to a switch C the diameter of which may be equal to that of the body, which leads to the possibility of increasing the number of switch contact-pieces.
  • a bolt unit 6 Inside the transverse housing lb there may slide freely a bolt unit 6 of which the total length is no greater than the diameter of the body 1.
  • the bolt and its housing are provided with cooperating slideways.
  • the locking end 6a of the bolt is narrower than the remainder of the bolt and may project completely outside the body 1 so as to engage the recess 8 formed in the ring B secured to the steering column.
  • a slot 6b is formed in the bolt so as to allow the rod 5a to always pass freely through the latter whatever its transverse location may be.
  • a spring 7 operating against torsion is fitted for instance round a bearing formed by a projection inside the transverse housing b (FIG.
  • the bolt 6 carries on its surface facing the driving member 5 two projecting sections adapted to cooperate for certain operative stages with the tenons 5b and 5c5d.
  • One of these projecting sections 6d is provided with a slope 6e adapted to cooperate with the tenon 5b and a relieved surface 6' preventing any contact of said projecting section with the sector 5d forming an extension of the tenon 5c.
  • the other projecting section 6 ⁇ is adapted to be engaged along its surface 6g by the tenon 5c and the nose on the sector 5d.
  • Said tenon 5c may be brought into a position facing the recessed surface 6h an extension of which forms the shaped surface 6i said projection 6f.
  • the latter is provided also with a relieved section 6) so as to provide room for the projecting end 4a of the key during the angular shifting of the latter, without any contact with the bolt.
  • a recess 6k is also formed in the bolt 6 and inside said recess, a block 9 is pivotally carried by a spindle 8 while a spring urges said block 9 into a position for which the latter acts as an abutment; inside the driving member 5 on the side facing the lock, there is formed an annular recess for a spring ll (FIGS. 10 and 11).
  • the latter operates against torsion and its ends 11a and Ilb are bent radially and outwardly so as to engage the radial ends of a sector-shaped opening 5g formed at the periphery of the driving member 5.
  • One end of the spring for instance the end 11a, may be shifted for a predetermined angular position of the driving member 5 by a suitably positioned stationary stud 2b carried by the cooperating surface of the lock stator 2.
  • the end of the key 4 includes an extension 4a adapted to extend through the driving member 5 and to cooperate with the block 9 on the bolt during predetermined operative stages.
  • the switch is controlled by the axial rod 5a in a manner entirely independent of the means controlling the bolt through the tenons'Sb and 5c5d and the end 40 of the key. This eliminates any objectional reactions, wedging, complex structures and the like difficulties.
  • FIGS. 13 to 21 The different operative stages are illustrated in FIGS. 13 to 21.
  • FIGS. 13 and 14 show the key, the rotor and the driving member in their locking position.
  • the bolt is not actually set in its operative position since the key 4 remains engaged in the keyhole and consequently its end 4a prevents the block 9 on the bolt from moving.
  • the tenons 5b and 5c are in a position for which they cannot prevent or disturb the shifting of the bolt towards the recess I3 provided for it in the ring B and the sector 5d may freely move over the relieved portion 6 of the front surface of the projecting section 6d of the bolt.
  • FIGS. 15 and 16 show the actual locking position obtained through engagement of the bolt end 60 inside the recess B when the key 4 has been taken out of the lock.
  • the bolt is urged automatically into its locking position by the spring 7. If the recess B does not actually register with the bolt the engagement of the latter ensuring the locking is obtained as soon as the steering wheel is slightly moved.
  • the tenon 5b is then in contacting relationship with the slope 6e on the projection 6d.
  • FIG. 17 illustrates the mechanism when the key is reinserted inside the lock.
  • the end 4a of the key is then located substantially underneath the block 9.
  • the bolt is caused to slide in the direction F under the action of the tenon 5b on the slope 6e.
  • the end 40 of the key enters a position in contacting relationship with the block 9 in the direction for which the pivotal movement of the block remains possible. Said block retracts and allows the movement of the key as illustrated.
  • FIG. 19 illustrates the parking position for which the steering gear is released while the electric circuits cannot be established so that the engine cannot be started.
  • the tenon 5b registers with the end of the slope 6e while the tenon 50 enter its operative position with reference to the slope 6g.
  • the bolt is always controlled by either of the tenons.
  • the end 4a of the key is not in contact with the bolt by reason of the relieved surface 6 formed in the projecting section 6f of the bolt.
  • FIG. illustrates the contact-closing position allowing the vehicle engine to run.
  • the angular movement of the key continuing in the direction of the arrow F the bolt has receded out of its housing and the ignition-controlling circuit is closed.
  • the tenon 5c reaches the recess 6h so that its position is clearly determined and this is readily perceived by the driver.
  • the spring 11 is subjected to an annular tensioning under the impact of its end 11a against the stud 2b (FIG. 11). As soon as the key is released, the spring 11 is alone operative and returns elastically the different parts into the contact-closing position illustrated in FIG. 20 and corresponding to normal running conditions for the engine. It is also possible, in accordance with my invention, for the elastic return from the starter-controlling position to the contact closing position to be obtained by resorting to the action of a spring associated with the switch C, which latter spring may replace the spring 11 fitted in the driving member 5 or else be associated with said spring 11.
  • My invention provides also simple arrangements adapted to prevent any undesired actuation of the starter during operation of the engine.
  • Such arrangements provide the advantage, in addition to their simplicity of being possibly associated intimately with the above-described antitheft arrangement since they are grouped within a small block with the mechanical section of said antitheft arrangement.
