Definitions

  • the present invention generally relates to electrically operated locking systems for doors and the like.
  • Electrically operated locking systems for doors for example, safety or security room doors, generally comprise a bolt locking unit installed on the inside of the door which is electrically coupled to a control unit which may be installed on the outside of the door or elsewhere, for example, at a central control room.
  • the control unit may be any of a variety of types, including those types using magnetic cards or keyed-in pass codes.
  • the function of the control unit is to ensure that only authorized persons may operate the locking unit.
  • an electrical pulse or current activates the bolt unit which withdraws the bolt from the door frame to unlock the door or inserts the bolt unit into the door frame to lock the door.
  • Such electrically operated systems tend to have sensitive internal mechanisms which are easily damaged if attempts are made to operate the bolt unit when the door is open or when it is closed for locking or unlocking thereof, but is not properly seated.
  • these devices are used to automatically operate the locking system upon the slamming of the door.
  • an object of the present invention to provide an electrically operated door locking system with an activating sensing device which overcomes some of the above-listed and other deficiencies of the conventional systems.
  • an electrically operated locking system for doors and the like comprising an electrically operated locking device installed inside the door, a control device installed outside the door operatively connected with the locking device, and sensing means for detecting the position of the door with respect to the door mounting.
  • the sensing means includes a light activated means electrically coupled to the locking device such that on sensing darkness, the locking device may be activated to operate the locking unit, and on sensing light, the locking device may not be activated.
  • the light activated means may comprise an optical sensor, such as a photocell.
  • the optical sensor may be installed on the inside, the jamb side or incorporated in the housing of the locking device.
  • FIG. 1a is an internal three-dimensional view of a vault or safe door fitted with a locking device and optical sensor according to a first embodiment of the present invention.
  • FIG. 1b is an exploded view of the locking device and optical sensor as shown in FIG. 1a.
  • FIG. 2 is a schematic diagram illustrating the operation of the locking system of the present invention.
  • FIG. 3 is a three-dimensional view of a further embodiment of the present invention.
  • FIGS. 1a and 1b there is partly shown a safe or like enclosed space denoted at 10 having a door 12 shown in an open position.
  • the door 12 may be of any known type.
  • the door 12 may be fitted with a locking device 14 installed inside thereof.
  • a control unit 16 (shown in phantom lines), may be externally fitted to the door 12 and electrically coupled by line L4 to the locking device 14 in any conventional manner (see FIG. 2).
  • a light sensitive element which may be in the form of an optical sensor 18 is located within the housing of the locking device 14 (or at any other location on the inner surface of the door 12) which faces the inside of the safe 10.
  • the optical sensor 18 is responsive to light, it can serve as a direct indicator of the door position. When the door 12 is properly closed, there is absence of light, and when door 12 is open, light is present.
  • the optical sensor 18, therefore, functions as a bi-stable activator element responsive to a closed/not closed position of the door 12.
  • the control unit 116 as shown in FIG. 3 may comprise a visual display to indicate the status of the system, for example, whether the door is open or closed or capable of being locked.
  • the optical sensor 18 is operatively connected to a processor P by way of a coupling represented by a line L1.
  • the processor P is further connected to the control unit 16 and the locking unit 14 by way of couplings represented by lines L2 and L3, respectively.
  • the control unit 16 and the locking unit 14 may be operatively interconnected by the line L4 in the usual manner. It is be readily understood from the following operational description of the system that line L2 is, in fact, optional.
  • optical sensor 18 senses the presence of ambient light energy which it converts into an electrical pulse.
  • This electrical pulse is transmitted by line L1 and interpreted by the processor P.
  • the processor P constantly receives information from an indicator normally associated with the locking device 14 (an internal micro-switch or the like) about the status thereof, namely being locked or unlocked.
  • a signal is sent by the processor P, via line L3, disabling the locking unit 14 and preventing it from being activated. If the door is "NOT READY FOR LOCKING", this position may be indicated on a visual display associated with the control unit 16.
  • the line L3 also serves to transmit information from the control unit 16 to the processor P.
  • the optical sensor 18 senses darkness (that is, the absence of light energy) and switches into its second operative state and informs the processor P accordingly.
  • the processor P having received an "OPEN" signal from the locking device 14 may then send a signal via line L3 enabling the control unit 16 and allowing for it to be operated according to its specific requirements (key, password input, etc). If the door is "READY FOR LOCKING/UNLOCKING", this position may be shown on the visual display mentioned above.
  • an electrical current is transmitted to the locking unit 14 via line L4 activating the lock bolt of the device 14 to lock or unlock the safe as required.
  • the locking unit 114 may be fitted within a door 112 of a security room or even a residential apartment.
  • the door 112 is fitted within a door frame 120.
  • the optical sensor 118 is installed at the jamb side of the door 112 since a "darkness" state prevails only when the door 112 is seated against its door frame 120.
  • the operation of the system is the same as described in connection with the embodiment discussed in FIGS. 1a, 1b and 2.
  • the present invention provides a locking system that is more simple and more reliable than that which has conventionally been used previously.
