Definitions

  • This invention relates to a locking system, and in the preferred embodiment provides a locking system particularly but not exclusively for locking the doors of a motor vehicle. It is to be understood, however, that the invention is not limited to such applications and may be generally applicable to other systems in which automatic locking is required.
  • the remote central locking system provides the user of a motor vehicle with an alternative to the conventional key in the form of a small portable transmitter. On activating the transmitter by means of a small button, the user may lock or unlock all of the doors of a particular motor vehicle. The user thereby saves the time required to insert a key into a keyhole in order to operate the locking mechanism. Whilst such systems are a considerable improvement they still require positive action on the part of the user of the vehicle in order to effect locking of the doors.
  • the first situation arises where, as a result of forgetfulness or deliberate omission, the user of the motor vehicle does not activate the central locking system upon leaving the vehicle.
  • This situation is particularly common in cases where vehicles are frequently left for short periods - e.g. in the case of delivery vehicles where many drops are made. With such vehicles a driver may accidentally forget to lock the vehicle on occasions or may deliberately omit the locking (and subsequent unlocking) of the vehicle because of the inconvenience involved.
  • one aspect of the present invention provides a door locking system comprising a lock mechanism for securing a door in a locked position and operating means for operating the lock mechanism so as to lock and unlock the door, wherein the operating means comprises the key and sensing means responsive to the position of the key, the sensing means adapted to move the lock mechanism into the locked position when the key is located beyond a pre-determined distance from the sensing means.
  • key is not limited to a conventional mechanical key for a lock, but rather refers to a device which is effective to trigger operation of the locking mechanism when it is located beyond the pre-determined distance from the sensing means.
  • the door locking system comprises sensing means adapted to move the lock mechanism into an unlocked position when the key is located at or within the pre-determined distance from the sensing means.
  • control means may be provided for varying the magnitude of the pre-determined distance.
  • the door locking system may be provided with overriding means which allows the lock mechanism to be moved into, and to remain in, the locked position whilst the key is located at or within the pre-determined distance from the sensing means.
  • the present invention has the advantage over the prior art of providing means for automatically locking a door as required by the user without the need of any conscious input from the user.
  • the invention allows the user to continue about his business without any regard to the locking of doors, but nevertheless, ensures that appropriate doors are locked as required.
  • Figure 1 is a side view of a motor vehicle incorporating a door locking system according to the present invention.
  • Figure 2 is a plan view of the motor vehicle of Figure 1.
  • a motor vehicle 2 incorporating an embodiment of the present invention is shown in Figures 1 and 2.
  • the motor vehicle 2 includes two side doors 3,5, and two rear doors 7,9.
  • the two side doors 3,5 are provided with lock mechanisms 4,6 respectively and the two rear doors 7,9 are provided with a single lock mechanism 8.
  • the lock mechanisms 4,6,8 are arranged so as to be capable of retaining the respective doors 3,5,7,9 in a closed and locked position.
  • the door locking system shown in Figures 1 and 2 includes the lock mechanisms 4,6,8 and operating means for the operation thereof.
  • the operating means includes an electronic key 10 which transmits a signal through the air, and sensing means 12 for sensing the signal.
  • the electronic key signal when received by the sensing means 12, causes the sensing means 12 to send a second electronic signal through wires 14 to the lock mechanisms 4,6,8 and thereby ensure that the lock mechanisms 4,6,8 are in an unlocked position.
  • the technology used by the sensing means 12 to communicate with the lock mechanisms 4,6,8 will be known to the reader skilled in the art and is used in conventional central locking systems.
  • the sensing means 12 and lock mechanisms 4,6,8 are arranged so that the lock mechanisms 4,6,8 move into a locked position as soon as the sensing means 12 stops sensing the signal from the electronic key 10.
  • the sensing means 12 is capable of sensing the signal from the electronic key 10 when the key 10 is located no more than a pre-determined distance X from the sensing means 12.
  • a control means (not shown) is provided on the sensing means 12 which allows the magnitude of the distance X to be varied to satisfy the requirements of the user.
  • Arrow A shown in Figure 2 indicates movement of the electronic key 10 from a first position, in which the key 10 is located less than the distance X from the sensing means 12, to a second position, in which the key 10 is located more than the distance X from the sensing means 12.
  • the sensing means 12 senses the signal transmitted by the key 10 and communicates with the lock mechanisms 4,6,8 so as to ensure that the lock mechanisms 4,6,8 are in the unlocked position.
  • the sensing means 12 is unable to sense the signal from the key 10 and so the lock mechanisms 4,6,8 are in the locked position.
  • the doors 3,5,7,9 are automatically locked by the respective lock mechanisms 4,6,8 as the user moves beyond the pre-determined distance X from the sensing means 12.
  • the doors 3,5,7,9 automatically unlock as the user moves within the pre-determined distance X from the sensing means 12.
  • Overriding means (not shown) is provided which allows the user of the motor vehicle 2 to lock the doors 3,5,7,9 even when the key 10 is located at or within the pre-determined distance X from the sensing means 12. The user may thereby lock himself and the key 10 inside the motor vehicle 2.
  • the "key" may comprise a badge worn by or attached to a person operating the vehicle.
  • the badge may be in the form of an ID badge carried by the driver.
  • the transmitter incorporated in the badge can be powered by single or multiple primary cells or by one or more secondary cells if a battery charging system is provided for the badge. If primary cells are used these should have an acceptable life expectancy - for example one year minimum.
  • Each "badge” has a unique ID code which can conveniently be programmed in at the time of manufacture.
  • the badge is designed at suitable intervals, e.g. between 10 and 20 seconds, to transmit its ID code using either a VHF or UHF signal via an integral antenna. It may be desirable for each transmission to comprise several continuous repetitions of the ID code so as to enable the sensing means on the vehicle to detect at least one full ID code.
  • the ID code is transmitted only at intervals in order to minimise power usage and minimise interference with other similar systems.
  • the ID code is transmitted at random or pseudo-random intervals.
  • the sensing means on the vehicle is programmed with the ID numbers of each of the badges which are valid to lock and unlock the vehicle in question.
  • the sensing means may incorporate recording means for recording the ID associated with each opening of the vehicle so that in the event of unauthorised opening of the vehicle the ID used to effect that unauthorised opening can be detected.
  • the sensing means will be effective to detect the ID signal up to approximately 10 metre range. If this range is considered to be excessively long given use of the vehicle in crowded conditions the sensitivity of the system can preferably be reduced by means of appropriate control within the vehicle. Whilst the invention is believed to be primarily of use in controlling the automatic locking and unlocking of the doors of a vehicle, it will be appreciated that it can be of much wider application. For example, the system can be used to control doors other than those of a motor vehicle. Further, it is envisaged that the system may be of use in controlling other devices. For example the operating controls of a machine may be enabled only when the authorised user of the machine is within a specified range of the machine. It should be appreciated in the circumstances that the term "locking" as used herein should be construed broadly as covering not only the physical locking of, for example, a door but also the disabling of control systems.
  • the invention is not limited to the specific embodiment described above. Alternative embodiments may comprise a different number of locking mechanisms and may be used in respect of doors other than those on motor vehicles.
