Definitions

  • the present invention relates to a vehicle door lock ⁇ ing arrangement which comprises a lock mechanism which includes a locking arm and which can be switched between a locking position in which the door opening mechanism is latched or blocked and a mechanism re ⁇ lease position in which the door can be opened.
  • the object of the present invention is to provide a solution to this problem by preventing a locked door of a motor vehicle from being forced by unauthorized persons, or to render such forcing extremely difficult to achieve.
  • the vehicle door cannot be opened by manipulat ⁇ ing the actual locking arm itself or by manipulating the pull-rod of a conventional lock mechanism connect ⁇ ed to said locking arm. Furthermore, the fact that the latching device is manoeuvered in response to an electric signal enables the device to be placed in the most possible inaccessible place within the vehicle door.
  • the control means preferably includes a reader which is intended to read an electric, optical or acoustic signal or a radio signal, and according to a preferred embodiment of the invention the latching device in ⁇ cludes a connecting element which is made of hard material, preferably case-hardened steel, which is connected to the locking arm of the lock mechanism, and a latching pin which is movable between a with- drawn and an outwardly projected position, said pin preventing movement of the connecting element of the latching device in the locking state of the locking arrangement and therewith prevent movement of the locking arm from said locking position.
  • a connecting element which is made of a hard material will prevent the connecting element from being severed from above through the gap defined by the window pane and the door plate.
  • the control device is constructed advantageously so that the manoeuvering signal will not be delivered to the latching device until a conventional lock cylinder has been turned by a key.
  • the latching pin of the latching device is spring-biassed towards its outwardly projected position and the connecting ele ⁇ ment includes a telescopic bottom end-part which is also spring-biassed towards an .outwardly extending position and which is so dimensioned and guided that in the locking position of the locking arm said bottom end-part will extend in its outwardly projected position beyond the latching pin whereas the bottom end-part is located outside the movement path of the latching pin when said end-part is in its withdrawn position.
  • the bottom end-part of the connecting element When the locking arm is in its locking position, the bottom end-part of the connecting element will press against the latching pin when said pin is in its outwardly projected position, and the latching pin is construct ⁇ ed so that it can only move to its withdrawn or re ⁇ tracted position when no load acts on the pin, so as to prevent blocking of the locking arm of a vehicle door that has been locked from within.
  • Figure 1 illustrates very schematically a vehicle door fitted with a locking arrangement constructed in accordance with a preferred embodiment of the inven ⁇ tion;
  • FIG 2 illustrates schematically the most essential components of the locking arrangement shown in Figure 1;
  • Figures 3-5 illustrate schematically a latching device included in the locking arrangement according to Figure 1, and show the latching device in various functional positions of the lock arrangement.
  • the illustrated lock arrangement includes a conven ⁇ tional lock mechanism comprising a locking arm 1 which can be moved between a locking position in which the opening mechanism of a vehicle door 2 is latched, and a release position in which the door can be opened.
  • the locking arm is typically connected to a lock cylinder 3 through the medium of a lever arm, so that the locking arm can be moved to and from its locking position by turning a key inserted in the lock in one or the other direction.
  • the locking arm 1 is also connected to an internally mounted locking button (not shown) through the medium of a pressure rod 4, so as to enable the locking arm to be moved to its locking and release positions from within the vehicle.
  • the conventional lock mechanism of the illustrated embodi ⁇ ment also includes a central lock 5 which is connected by means of a lever to the locking arm for movement of said arm.
  • the lock arrangement in ⁇ cludes a latching device 6 which is mounted within the vehicle door and attached to the bottom thereof.
  • the latching device 6 is comprised mainly of a latching element 7 and a pull-rod 8, one end of which is con- nected to the locking arm 1 and the other end of which can be held firmly by the latching element in a manner described in more detail herebelow.
  • the latching element is manoeuvered electrically and is connected to a control means 10 by an electric conductor 9.
  • This control means 10 includes a reader which in the preferred embodiment of the invention is intended to receive a coded radio signal transmitted by a trans ⁇ mitter fitted to the standard key of the vehicle door.
  • coded signals can be used as an alternative to radio signals, for instance electrical, acoustic or optical signals with the aid of a corresponding transmitter and receiver.
  • the lock arrangement also includes an electric contact element 11 which is intended to coact with an electric contact element in the lock cylinder, such that the control means is unable to deliver a manoeuvering signal to the latching element until the key is turned.
  • the control means is also constructed in a manner which makes it necessary for a manoeuvering signal to be delivered to the latching device within thirty seconds after the reader of the control means has received a correct code signal .
  • the bottom part of the pull-rod 8 is comprised of two parts 12, 13 which are mutually connected by means of a bolt 14 which extends through holes whose axial extensions and widths exceed the diameter of the bolt, such that the two parts 12, 13 can be moved in an axial direction relative to one another.
  • the lowermost part 13 of the pull-rod 8 is terminated downwardly by a generally cylindrical head 15 which has a sharp upper edge and a rounded bottom edge.
  • the lower end of the pull-rod 13 extends in an axial bore 16 in a cylinder piece 17.
  • the latching element 7 also includes a locking pin 18 which extends in a radial opening 19 in the cylinder piece and which is urged by a spring 20 to a position in which the pin projects outwardly into the bore 16.
  • the locking pin 18 is withdrawn from the bore 16 with the aid of a solenoid valve 21. That part of the locking pin which extends out into the bore has a semi-circular recess whose diameter corresponds to the diameter of the portion of the pull-rod part 13 locat ⁇ ed above the head 15.
  • the latching element also in ⁇ cludes a spring 22 which endeavours to press the head 15 of said part 13 downwards in the bore 16.
  • the latching device 6 is in its latching position and the pull-rod 8, whose upper end is connected to the locking arm in this state of the lock, is prevented from moving upwards by the locking pin 8 which projects outwardly above the he'ad 15. Neither can the locking arm 1 be moved out of its locking position, unless the pull-rod is de- stroyed.
  • the rod is preferably manufactured from hardened steel.
  • the key holder When wishing to unlock the car, the key holder acti- vates the transmitter which then transmits a coded signal which is read by the reader of the control means.
  • the control means is therewith activated to deliver electric current to the solenoid of the latch ⁇ ing element. No current is delivered to the solenoid, however, as the solenoid circuit is not complete.
  • the control means is activated for thirty seconds and is deactivated if current is not delivered to the sole ⁇ noid valve within this time period.
  • the sole- noid valve circuit is completed and the solenoid valve 21 withdraws the locking pin 18 from the bore and the pull-rod is moved upwards at the same time as a result of the locking arm being moved from its locking posi ⁇ tion to its release position.
  • the control means is also constructed to deliver current to the solenoid valve over a short period of time, and consequently the locking pin will be returned to its outwardly projected position in the bore 16 immediately after the pull-rod has been pull upwards by turning the key.
  • the latching element has now taken the release posi ⁇ tion illustrated in Figure 4.
  • the conventional lock mechanism can be manip ⁇ ulated in a conventional manner from the unlocked state of the lock arrangement shown in Figure 4 , independently of the latching device.
  • the latching element will take the position illustrat ⁇ ed in Figure 5.
  • the parts 12 and 13 of the pull-rod are connected together in a manner which enables these parts to be moved axially in relation to one another, the locking arm can be moved to its locking position without the part 13 being able to move to its bottom end-position shown in Figure 3.
  • Such an embodiment is desirable in order to enable cars to be driven through areas of high criminal activity with the doors locked from within.
  • the latching-pin movement mechanism is constructed so that the pin can only be withdrawn from the bore 16 by the solenoid valve 21 when no load acts on the pin.
  • the pin 18 is loaded by the head 15 and by the force exerted by the spring 22.
  • the pin will therewith be pressed down into abut ⁇ ment with the bottom surface of the opening 19.
  • the solenoid valve is dimensioned so that the force gener ⁇ ated thereby will be smaller than the sum of the force exerted by the spring 20 and the frictional force acting between the pin and the bottom surface of the opening 19.
  • the underside of the head on the bottom part of the pull-rod and the upper side of the latching pin include mutually coacting projections and recesses which function to prevent the latching pin from being drawn out of the bore when the door has been locked from within the vehicle. It is also conceivable to provide the underside of the pin with a projection which is pressed against an abutment surface in the radial opening of the cylinder piece if the pin is pressed downwards by the pull-rod head.
  • the spring which endeavours to move the two pull-rod parts away from one another may be configured in some other way and may advanta ⁇ geously be placed at the connecting join between these parts, so as not to load the locking arm in its re ⁇ lease position.
  • the upper pull-rod part 12 may be replaced with a steel wire, therewith sim- plifying the connection between the two parts of the connecting element. The invention is therefore re ⁇ stricted solely by the contents of the following Claims.
