Definitions

  • the invention concerns a mechanical locking device and electronic circuits that control and unlock this locking device and where they are functioning together, as one, they actually form a locking system that secures every kind of door panel or lid, on its closed position which means that, this locking system is a high security lock which consists of the locking crook mechanism with the locking tap, of the central electronic unit of control and unlocking and of the access system with codified commands,using a kind of electronic key or a key-pad or a magnetic data card or even a combination of them. Additionally the invention concerns a method by which the mechanical strength of the door panel can be reinforced at the same time that the door is locked and this method is based on the characteristic operational way and also on the fitting arrangement of the crook mechanism and the locking tap, which are presented in this invention.
  • the security against burglary that the conventional locks provide is mainly based a) on the private lock barrel with an enclosed exclusive, unique, combination of small pins or plates and b) on the strong structure of the lock mechanism itself and on the strength of the locking point, in the frame, as well. Also it should be noticed that because of the size of the conventional lock and for a convenient use, only one lock is normally fitted in each door, which consequently provides only one locking point, unless the type of lock with toggle levers is fitted which provides additional locking points, but such type of lock is not being in wide use, especially to the existing doors, because it should be fitted on the door panel externally and having large dimensions is particularly antiaesthetic.
  • a main disadvantage of existing locking system is the location where the barrel of the pin combination is fitted , which although is the most important part of the lock and it is in direct relation with the security provided by the lock, however, this part is easily reached by everyone and as it might becomes useless or can be damaged easily by many ways, it is the burglar's favourite point of breaking in.
  • Some other weak points of the locks known today are that they can not be fitted to the sliding doors, but only to the hinged doors, because of their operating way, that when a key is lost, expensive and time wasting problems will be risen because in most cases, a lock specialist should be called to open the door and precautionary the private lock barrel or even more the lock mechanism may to be replaced, if the lock barrel is not replaceable.
  • Another weak point concerning the existing locks is that when the door unlocks from a remote location, this can be done only by wires, it depends al ways on mains supply and provides less safety. Furthermore when we have many doors, we must carry the correspondent keys, with consequent problems.
  • This invention concerns a self-locking device which can be controlled by either, electronic or mechanical way and whenever the device is used to lock a door, is functioning as a lock, by the meaning that there is for the existing locking systems with conventional locks, but also this device can be used for other applications, with small modifications of its form.
  • the whole locking system of the present invention e.g. both the mechanical and the electronic parts, is a self-locking lock and from now on, this will be called “the present lock” due to the main purpose which is made for.
  • this invention concerns a method by which the mechanical strength of the door panel can be reinforced at the same time that the door is locked and this method is used in combination with the present lock.
  • the installation of the present lock can be done easily on the existing doors and the disadvantages of the conventional locks are eliminated.
  • the already fitted conventional lock can be stay in place, at the same door, together with the present lock, or it can be removed as it is desirable.
  • the many advantages and the electronic features of the present lock enable it to has a high operative flexibility and so that the field of the use of the locks is wider, ensuring at the same time high security to all applications and even more they could revise today's consideration and practice for the security of the rooms by the means of doors and locks.
  • the mechanism can be fixed either, in the movable or the immovable part of the door and in the most proper place that can be selected, regardless if this place is easy to be reached by hand or not and also the mechanism is functioning on any inclination. Further, every time the door closes, all fitted mechanisms is locked simultaneously, and they unlock all together, as well.
  • the mechanisms unlock by a combination of numbers which is set by the user and also the electronic-like key can be used to unlock any door where the present lock is fitted by changing the code number only, the present lock may to be a part of a central alarm or computer system, it can be controlled remotely by wires or wireless ensuring the same high level of security and many other advantages which will be mentioned later on.
  • the self locking lock as it is mentioned in the title of this invention is an assembly of independent mechanisms and electronic circuits which as they cooperating together, they give the characteristic function of the present lock as well.
  • every single part of the assembly has its own particular characteristics, but all characteristics, of every part, as a total, are defining rightfully the characteristics of the present lock as a system.
  • the present lock consists of the locking crook mechanism (20) with the locking tap (21), of the central electronic unit for control and unlocking (22), of the access system with codified commands (23), of the electronic-like key (24) or a key-pad and of the secondary circuits (alarm, power supply e.t.c) and the necessary wirings, as it is shown in Fig. 1.

  • the crook mechanism is fixed in the door frame or in the door panel while the locking tap is always fixed on the corresponding opposite part of the door, than this one where the crook mechanism is placed and they are fixed in such a way so that a short portion of the projected length of the locking tap can be inserted into the crook mechanism.
  • the crook mechanism consists of the shell (25) which is the stationary part of the mechanism and it can be fixed in either, door panel or the door frame and itself is a strong closed case, formed in a proper shape so that to surround the locking crook (27) with small clearance and also has an opening in a specific place, named the passage (26) of the locking tap which ensures the rectilinear incoming and outgoing movement of the locking tap to the crook mechanism, of the locking crook (27) which is enclosed in the shell and is able to be rotated partially around of two possible centres of turn, alternatively, and it is a disc plate which has a cut that gives to the crook a hooked shape and into this cut, the locking tap can be slid in, when the open end of the cut is aligned with the passage in the shell, of the crook pivot (28) which rests freely across the sides of the shell and it can be moved, by a horizontal and parallel to its own axis motion, from the point (A) which is considered as the
  • the crook catch (30) which is a kind of ratchet and it is hinged on the shell in such a way in order to engage or not, selectively, with a proper point of the crook, and which point is the auxiliary possible centre of turn (B) of the crook, while the engagement or disengagement of the crook catch is caused by the electromagnet (31), (or electric motor, or conventional system with lock barrel and key) which is included in the crook mechanism although it is an electric component of the present lock and finally, of the locking tap (21) which is a mechanical part of the crook mechanism but it is not included in to the shell.

  • the locking tap (21) which is a mechanical part of the crook mechanism but it is not included in to the shell.
  • the locking tap is a strong rod from which a little straight portion of one end can to slide into the cut of the crook through the passage of the shell, in such a way and position, so the axis of the incoming portion being vertical on the crook plane and parallel to the axis of the main (A) and auxiliary (B) centre of turn, while each centre, independently, can to become the instant active center of the crook rotation and also can to be the centre of a moment that produced by the force which is applied by the locking tap on the contact points with the sides of the crook cut due to the motion of the locking tap when it is going in and out of the mechanism.
  • the rotation of the crook inside the shell is according to the direction of the locking tap motion and also to the instant active centre of turn of the crook, so that the open end of the crook cut either is aligned with the passage or not, opening or closing the open end of the passage.
  • the crook mechanism is characterized in that the way of operation of the crook which can to turn round of two, or more points, but only one of these points can be selected every time so to be the instant active centre for the crook rotation and the selection of each of the points, to be the instant active center, is according to the desirable direction of the crook motion inside the shell, so that, the crook is to realise or to trap the locking tap into the mechanism, is characterized in that the characteristic movement of the crook is caused by a moment with a proper direction and magnitude and which moment is created when the locking tap applies a force to its instant contact point with the one of the sides of the crook cut, during the incoming or outgoing motion of the locking tap into the cut, while the centre of this moment is the instant active centre of the crook turn, is characterized in that any breaking force of the door panel is not handled by none internal element of the mechanism, but the force is handled totally by the shell of the mechanism, indirect and through the locking tap and the wall of the crook which is pressed against the
  • the function of the crook mechanism of the present lock is easily understandable.
  • the locking tap is been inserted into the mechanism by a rectilinear movement through the open end of the passage of the shell and enters into the crook cut, of which the open end is already aligned with the passage which in this case acts as a guide of the locking tap movement.
  • a force is applied by the locking tap. This force produces a moment which having centre of application the main center of turn (A), which now is also the instant active center, forces the crook to turn according to the direction of the force.
  • the rotation of the crook continues as far as the locking tap is going in the mechanism and until the crook catch engages the crook in the point (B) which is the auxiliary center of turn of the crook and in that position the crook is held still, e.g. in the locking position, trapping the locking tap inside the mechanism as well.
  • the locking tap is to exit the mechanism and if the crook catch is disengaged, by an electromagnet or a mechanical system, then the centre of the moment is the main center of turn (A), which is active again and as the direction of the moment is the opposite of the incoming one, the open end of the crook cut can be aligned with the passage of the shell so that the locking tap can be moved out of the mechanism.
  • A main center of turn
  • the central electronic unit for control and unlocking from now on called with the acronym CEUCU is the main electronic part of the present lock which ensures the security provided by the lock as the CEUCU is controlling the electromagnets or the electric motors to unlock the crook mechanisms only when the codified incoming data comply absolutely to the data stored in the CEUCU memory and also if at the same time there are the conditions which satisfy some additional parameters which are set selectively.

  • the CEUCU of the present lock which has been described above, is the basic unit and includes all the basic functions of the lock, as it is already made and tested. However, the abilities of the modern electronics are grown fast and possibly they will provide to this basic unit, a higher flexibility in the way of function and the design of CEUCU concerning the way of unlocking.
  • the CEUCU is functioning in such a way so that the combination number loaded in the data memory can not be detected, theoretically and practically, because the input data do not effect in the memory directly, but indirectly, through other verifying circuits which control and lock the input data and furthermore it should taken into consideration that every unlocking process starts always from the beginning and for all of the individual digits of the combination number at the same time, and for the unlocking of the mechanisms the input data have to coincide with the data loaded in the data memory.
