Definitions

  • the present invention relates to a lock primarily intend for motor vehicles but which may be used for oth purposes.
  • Motor vehicle locks commonly comprise a barrel type lock which the key when inserted is turned to switch on vehic services then to actuate the starter motor. It is comm to include a steering column lock to prevent the steeri wheel from being turned when the key has been removed fr the lock.
  • Many of these locks have, however, only limit security in that they can be picked, forced, shimme drilled or extracted without great expertis Consequently, there has been a tendency to fit alarms t vehicles. These, however, are increasingly ignored and ca themselves be circumvented.
  • a lock according to the invention comprises a housing, key receiving barrel mounted in the housing, the barre capable of axial movement relative to the housing, means t constrain the axial movement of the barrel, sai constraining ' means comprising an electrically operabl solenoid arranged to be actuated by an initiating signal.
  • the lock is arranged to actuate an electrical switch to provide electrical supplies to a vehicle and may also actuate a starter motor.
  • the lock may also be adapted to move a bolt into and out of a steering column.
  • the initiating signal is derived from an infrared receiver within the housing
  • a sensor is mounted to a front face of the lock housing.
  • the receiver circuitry is housed within the housing. If a correct infrared signal is received by the receiver the solenoid will be actuated to prevent axial movement of the lock barrel. This enables a correct key to be inserted in the lock barrel without upsetting the lock. The key can then be turned to remove a steering wheel lock where this is fitted. The key can be then further turned to actuate an electrical switch and to start a vehicle engine.

  • the lock shown is adapted to be fitted to a steering ' column (not shown) of a motor vehicle.
  • the lock comprises mainly cylindrical housing 1 in which a key slot 51 (see Fig. 1) is axially provided on axis X.
  • the cylindrical part of the housing contains a lock barrel 2 with an axially extending round portion 2a terminating with a double D section 2b (the double D section being shown at 52 in Fig. 2) .
  • Below the cylindrical part of housing 1 is a radially extending portion 53 housing a steering shaft lock bolt 21 and a parallel radially extending portion 54 housing a solenoid 14 for locking barrel 2.
  • the portion 53 extends to a bracket portion 55 arranged to receive bolts (not shown) in bolt holes 56 (see Fig. la) .
  • the bolts secure the lock to the steering column tube (not shown) .
  • the lock barrel 2 also has at its outer key entry end a key stop portion 2c at the key entry which houses a plate 3 which is enabled to slide in a direction B (shown in Fig. 2a and 7a) . Details of the portion 2c and plate 3 are shown in Fig.s 7 to 8a.
  • the barrel 2 is rotatably mounted in a sleeve 4 and secured axially thereto by a circlip 4a (see Fig. 2a) .
  • a hardened steel liner 5 Surrounding the outer part of the barrel 2 is a hardened steel liner 5 to protect the barrel.
  • the sleeve 4 with barrel 2 is shown in Fig. 2 in the lock operative position but is movable axially in chamber 57 to the rear to an upset position, cavity 6 in block 7 allowing key 12 extending from sleeve 4 to rotate in the upset position.
  • Behind block 7 is a fixed block 8 to provide support to plunger 9.
  • Plunger 9 is normally pressed by compression spring 10 onto sleeve 4, spring 10 acting between the plunger 9 and solenoid armature 15.
  • Armature 15 is normally pressed outwards away from sleeve 4 by means of compression spring 11.
  • Sufficient pressure is provided by spring 10 to ensure plunger 9 provides a slight drag on sleeve 4.
  • spring 11 resets armature 15.
  • a keyway 13 (see Fig. 5) is provided in block 7 which guides key 12 extending from sleeve 4. Key 12 is released from keyway 13 as indicated above on key 12 moving rearwardly to coincide with cavity 6.
  • Block 16 has a groove way 17 into which plunger 18 can be pressed by spring 19. Plunger 18 acting in way 17 prevents barrel 2 and sleeve 4 from being pulled forward. That is plunger 18 retains the barrel in the rearward or upset condition.
  • FIG.s 2, 6c-e To the rear of block 16 is a spacer 58 beyond which is an operating block 20 (see Fig.s 2, 6c-e) which can move radially under pressure of spring 23.
  • Block 20 is arranged to act on bolt 21 and to retract bolt 21.
  • a further spring 22 acts between bolt 21 and block 20.
  • Figures 6a and 6b show a cam assembly 24 held in position by circlip 26 to plate 25 mounted to the rear of block 20.
  • a track 24a designed to give a positive lift to block 20 engages with a lug 24b extending from assembly 24.
  • Lug 24b engages with and 20a in block 20 (see Fig. 6c) when the key '' is turned towards the engine start position.
  • Spring 23 acts on the block to rotate spindle portion 2a to the engine running position.
  • a further circlip 27 secures plate 25 in the housing to the rear of assembly 24 a dog member 28 engages assembly 24 and is movable rearwardly by face 60 at the rear end of extension 2a.
  • a compression spring 29 maintains dog 28 and assembly 24 in contact through plate 25 and also serves to maintain movable contact plate 30 and fixed contacts 31 in operable association.
  • An insulating sleeve 32 which carries spring 29 prevents spring 29 from obstructing movement of dog 28.
  • An electrically insulating block 33 held between ridge 61 of contact housing 36 and circlip 35 provides a mounting for fixed contacts 31.
  • Block 33 (see Fig.s 2 and 3) has a membrane 34 which maintains the working pressure needed for the contacts and also prevents upset of the lock in the engine running condition.
  • membrane 34 is also designed to shatter at a predetermined loading occasioned by impact on barrel 2 and extension 2a and 2b. This shattering of the membrane can be used to disable the switch in the event of highjack or else can be used in a crash to disable the switch.
  • Contact housing 36 is held to main housing 1 by circlip 37.
  • An insulated block 38 providing an abutment for spring 29 is held to extension 2b by circlip 39.
  • a lever 40 in the forward part of housing 1 acts to obstruct operating block 20 from locking the steering.until the key is removed from barrel 2.
  • the outer end 40' of lever 40 rides on plate 3 and lies between 2c and 2d depending on whether the barrel 2 is in the forward operative position shown in Fig. 2a or in the. rearward upset position.
  • a trip pawl 41 is in operating block 29 under influence of spring 42 (see Fig. 2a) .
  • a spring 43 ensures lever 40 remains clear of pawl 41 in locked condition.
  • a microswitch 44 below lever 40 indicates that the key is left in barrel 2 if vehicle door is opened.
  • a cavity 46 in the main housing 1 is provided for an amplifier and decoder for infrared sensor 45.
  • the amplifier applies an initiating signal received by sensor 45 to operate solenoid 14.
  • cavity 46 contains a magnetic strip readout receiver, the strip being inserted through a slot shown in broken line at 45' in Fig. 1 replacing sensor 45.
  • the circuit for the magnetic strip readout is inserted as shown in Fig. 11 at 64.
  • the circuit for switch 62' operates as switch 62 below.
  • a coded infrared signal from a customised fob unit comprising a conventional infrared signal transmitter 60 shown in Fig. 9 but which is not described in detail because it is a well known proprietary item.
  • the infrared signal is received by sensor 45 mounted in the front face of the lock housing 1 and is amplified and decoded by an integrated receiver unit 61 (see Fig. 10) all housed within cavity 46. If the signal is correct the solenoid 14 within the housing will actuate and prevent axial movement of the lock barrel 2 and allow insertion of the correct key whereby release of steering and start up of the engine can be achieved in a normal manner.
  • switch 62 which is part of the ignition switch opens and disables the receiver.
  • a predetermined time delay in the enabling circuit of the receiver unit ensures that if the key is not operated within the predetermined time, the solenoid will release the constraint on the key barrel.
  • microswitch 44 It can also be arranged that an alarm can be activated should the device be put into the upset condition.
  • This arrangement of the apparatus is such that an incongruous or undesirable situation cannot arise in that it should be impossible to have the steering locked and the engine on or the key withdrawn unless the steering is locked.
  • any two barrel levers should have the external widths made small to prevent the picking of the lock by holding against the housing.
  • any two levers should have the internal apertures made slightly larger than normal to make it impossible to hold the levers with a central probe.
  • This device is such that a combination of electronic control within a sealed unit having a minimum of wires together a robust mechanical lock contributes much to auto security.
  • the strip is fully inserted into the lock housing at which stage nothing happens other than to operate an initiating switch.
  • the strip must be then withdrawn when readout occurs. This method of operation ensures that the strip cannot be left in the lock whereby security is compromised. From when the strip is fully inserted to the turning ON is completed there is a time feature.
  • the magnetic strip embodiment may be more expensive than infrared embodiment type, and care with strip alignment must be exercised.
  • the strip is liable to become damaged with use although it would be no problem to carry a spare in a secure environment.
  • a damaged strip or circuit failure would not render the vehicle unusable because of the reset facility with the correct key. For vehicle servicing, only the key needs to be handed over, the magnetic security number remaining with the user.
