Definitions
- the invention relates to a method, in which in and out passage to or from a certain room or area, preferably a building or enclosure, is controlled via an automatic door system, in which automatic door system a locking system is provided, which comprises at least three main components including at least an operating panel, a control unit and a motor-lock.
- the invention also relates to a locking system comprising at least three main components including at least an operating panel, a control unit and a motor-lock.
- the invention relates to an electromechanical motor-lock for use in a method or in a motor-locking system according to claims 1 or 2, which motor-lock is intended to be fitted to a device closing an opening, preferably a door, which motor-lock comprises a rotary lock mechanism and a motor-lock mechanism.
- a typical feature of such locking systems is that they comprise three main components, to be precise an operating panel, which comprises a receiver for registration via transmission, reading or entry of an authorization code, for example a card reader or key set, a control unit with a microprocessor, which receives the signal from the operating panel for verifying that an approved authorization code has been entered, and one or more electromechanical motor-locks, which are fitted to at least a door, outer door or the like at said room or enclosure.
- an operating panel which comprises a receiver for registration via transmission, reading or entry of an authorization code, for example a card reader or key set, a control unit with a microprocessor, which receives the signal from the operating panel for verifying that an approved authorization code has been entered, and one or more electromechanical motor-locks, which are fitted to at least a door, outer door or the like at said room or enclosure.
- Motor-locks are distinguished from normal locks in that they have an electric motor for retracting and extending a latch bolt, usually in the form of a catch bolt. Motor- locks can also have a further catch bolt, the open and locking position of which is controlled via a key-operable cylinder mechanism, a handle and/or a turning door handle, and in addition more often than not a normal spring bolt.
- Catch bolt means a bolt with a generally rectangular cross-section and a level end face, which bolt has at least two fixed end positions, which consist of a position barring and a position releasing the door, while a spring bolt is understood to mean a bolt, likewise with a usually rectangular cross-section but with a bevel-cut end face, which bolt is adjusted by means of the door handle between two end positions, which consist of a retracted and a projected spring end position.
- the function of the control unit's microprocessor is to emit a signal following checking and possible approval of the authorization code received to put the latch bolt of the motor-lock into its open or locking position.
- lock compartment of which the outer dimensions have an upper limit in accordance with the prefabricated and thus standardized recesses of the type- approved door or outer door for the lock compartment, in order thereby to always fit into these recesses.
- the lock compartment thus has a set, limited inner space, which cannot be filled completely without reservations as to what can or must be included.
- the contents of the lock compartment must therefore be optimized according to the intended use of the lock, where a compromise has to be made between the desired requirements for the strength of the lock compartment and for example the number of latch bolts included, etc.
- the inner space in a motor-lock compared with a normal mechanical lock, is also filled by components required for the function, such as an electric motor and other necessary components for this, such as cabling, which is why there is no motor-lock on the market up to now which meets all the requirements set for Swedish standards and for approval by the insurance companies for mounting in a conventional lock compartment for a type-approved door.
- a further problem is that in all previously known and comparable motor-locks, the user has had to wait a relatively long time for the latch bolt to reach the appropriate end position before the door can be opened, or is locked.
- the required locking time i.e. the bolt movement from the unlocked to the locked position and vice versa, takes up to several seconds in many known motor-locks.
- the electric motor for these locks has been optimized for extending and retracting the latch bolt even when the door panel is not in the fully closed position, i.e. the door panel continues to stand slightly ajar so that the recess for the latch bolt in the door frame is not exactly in line with the latch bolt, for which reason the friction forces which occur in this case have to be overcome by the electric motor.
- a lock of this kind requires a larger and slower electric motor, on the one hand to overcome said friction forces and on the other to prevent the lock from jamming fast if pushed in too quickly.
- opening and locking it is desirable for opening and locking to be able to be executed much more quickly, even up to 10 times faster. Even a wait of just 2-3 seconds can be found to be highly irritating by certain users, especially if passage in and out takes place often.
- the latch bolt is therefore often set to the open (unlocked) position during the daytime, as doors of this kind otherwise tend to be set in the open position by means of an obstruction in the door spring by certain users, resulting in the lock not only being unlawfully disabled but also in the risk of the lock being forgotten altogether in the open position, or of the alarm being triggered unnecessarily if one is installed.
- the object of the present invention is to eliminate or at least reduce the aforementioned problems.
- the method according to the present invention is characterized in that a random code is sent from one main component to another after a user has entered an authorization code at a registration device, which code is converted in an activation circuit card to a first random code, which varies randomly between each such main component and also each time an authorization code is entered, which random code is received and checked by the control unit, following which yet another random code is sent to the motor-lock, which transmits its current status back to the control unit, following which a third random code is transmitted to the motor-lock to open its latch bolt by means of an electric motor.
- each main component comprises at least an activation circuit card for receiving authorization codes and/or random codes, for conversion between these authorization codes and random codes and for transmitting random code from one main component to another, which motor-lock includes reinforcement plates for reinforcing the lock compartment of the motor-lock
- the motor-lock accordmg to the present invention is characterized m that the motor-lock furthermore comp ⁇ ses reinforcement plates, a blocking arm for blocking of a latch bolt, which is disposed via an operatmg device to be guided m a linear movement between a projected position latching the device and a retracted position releasmg the device by means of an electric motor, which movement is controlled by the control unit, which is disposed to transmit a random code based on an autho ⁇ zation code from one main component to another, and that each such main component comp ⁇ ses at least one activation circuit card for conversion between authorization codes and said random codes
- a locking system is achieved due to the present invention in which the motor-lock cannot be tampered with only by repeating a read signal in one of the cables between the main components forming part of the locking system, l e the operating panel, control unit and motor-lock, to achieve unauthorized lock opening
- the locking system always senses that the device which closes the opening to the lock-protected room or area, for example a door, is really in the correct position before the electric motor is started, the motor latch bolt does not need to align the door panel in relation to the door frame, for which reason no greater strength of the elect ⁇ c motor is required
- the elect ⁇ c motor is therefore a considerably smaller model than that of the motor-locks otherwise obtainable on the market, and it is also specially adapted to guide the latch bolt forwards and backwards between its end positions considerably more quickly than in comparable motor-locks It has been possible surprisingly to reduce the locking time to approx 10 % of the corresponding locking time for comparable motor-lock designs, l e it has virtually been eliminated Thanks to the use of the much smaller and also considerably cheaper electric motor, the invention solves not only the problem of the extremely long locking time of up to several seconds at present, but also the problem of the minimal space inside the lock compartment is solved, as the smaller motor automatically gives extra space for greater reinforcement of the lock housing to make breaking in more difficult, which is achieved
- the advantage is also gained that predetermined geometrical spaces, tracks, surfaces or ducts can be created with optional extension in all directions for laying cables or for accurate three-dimensional mounting of defined components or sliding surfaces.
- the stationary or moving parts arranged in the lock compartment can thus be formed to be considerably thinner than previously, as they do not need to have the same thickness as the lock compartment to obtain the required supporting and /or sliding surfaces, at the same time as all the previously unutilized empty space is now filled with reinforcement material.
- the present motor-lock therefore copes with considerably greater loads in all directions than the corresponding conventional lock compartments, in spite of the external dimensions being essentially identical to one another to fit in the same recess.
- Fig 1 shows a door in diagrammatic form with parts of a locking system according to the present invention, which locking system comp ⁇ ses a motor-lock, an operating panel and a central control unit with cables laid between the integral components

- Fig 1 shows a locking system 1 accordmg to the present invention, which is intended to control in and out passage through an openmg to or from a certain closed room or defined area, for example a building or an enclosure
- the locking system 1 comprises three separate mam components, to be precise an operatmg panel 2, a control unit 3 and an electromechanical motor-lock 4, between which mam components 2, 3, 4 suitable cables 5, 6, 7 are laid for transmitting signals and a power supply
- the mam components 2, 3, 4, which can be more than one of each type, together constitute a complete system 1 in which all mam components 2, 3, 4 are integrated with one another
- Each main component 2, 3, 4 is unique in such a way that it is prepared so that if one or more of them need to be exchanged, the new component 2, 3 or 4, plus those remaining, can be adapted easily and without the aid of an external computer to function together directly following connection to the system 1 by means of "button pressing", desc ⁇ bed m greater detail below
- the room or area has a device 8 for closing said opening, such as a door, outer door, wmdow or gate, preferably a type-approved door 8
- Type-approved door 8 means a prefabricated door, which comprises a door panel 9, which is fitted m a door frame 10, and in which door panel 9 and door frame 10 predetermined recesses 11, 12 are included for the motor-lock 4, which is standardized with regard to its outer dimensions
- the motor-lock 4 comprises a lock compartment 13 and at least one latch bolt 14, for which said recesses 11, 12 of set dimensions are thus provided with a good fit with regard to the height, depth and thickness of the lock compartment 13 and the latch bolt 14 respectively
- the operating panel 2 is arranged outside and at best closely adjacent to the openmg through which in and out passage to or from the lock-protected room or area is to take place

- the information earner 17 can consist for example of an electromechanical key of a known type, which has been personalized m some suitable manner, or, in the case of a registration device 16 consisting of a card reader, of a card with a magnetic st ⁇ p 19, a bar code, microcircuit or the like, which card is inserted in a known manner into a slit 20 for registe ⁇ ng the autho ⁇ zation code Bl,
- a transmitter 23 is provided m the form of an activation circuit card in the enclosure 15 of the operatmg panel 2 in a manner which is safeguarded against outer damage and against external reading of said first signal SI generated
- the activation circuit card 23 comprises a signal converter 24, for example a microprocessor or a circuit card of the type KEELOQ, for converting the first signal SI generated in the registration device 16 into a va ⁇ able, "random" code HI
- Random code HI means a code which is always changed on each new registration of an authorization code Bl, B2, B3 etc in the registration device 16, regardless of whether the authorization code Bl, B2, B3 etc is incorrect, correct, the same or new
- the random code HI which m the embodiment described consists of a 66-bit code, thus vanes between each new passage m or out through the openmg, mcludmg between each attempt to register an authorization code Bl, B2, B3 etc , thereby eliminating the ⁇ sk of unlawful openmg of the door 8 by repeating
- the signal converter 24 comp ⁇ ses a built-in random number generator 25 for generating a binary number of a certain length, which number vanes randomly each time the activation circuit card 23 is activated by said first signal SI from the registration device 16
- the signal converter 24 of the activation circuit card 23 is set to utilize the bmary number and the first signal SI for a predetermined numencal calculation, a new, second signal S2, based on the read or entered authorization code Bl, B2, B3 etc and the binary random number provided by the random number generator 25, being set to be generated, which thus forms the both coded and constantly changed "random" code HI for each activation occurrence
- the activation circuit card 23 can generate at least a million possible random codes HI in separate combinations for each activation occu ⁇ ence Each activation is disposed to last for approx 3 seconds
- An external cable 5 is a ⁇ anged from the activation circuit card 23 for transmitting the random code HI to the control unit 3, disposed at a distance from the operatmg panel 2 inside the lock-
- the control unit 3 comprises a receiver m the form of a second activation circuit card 26, which is set to receive the random code HI from the activation circuit card 23 of the operating panel 2 for "decoding" to the factual authorization code Bl presently entered or read via the registration device 16, a mam processor 27 for processing incoming and outgoing signals, for example checking the decoded authorization code Bl against approved authorization codes Bl, B2, B3 etc stored previously in a memory 28 of the mam processor 27, and a transmitter m the form of a third activation circuit card 29 for converting a first and a second opening signal S3, S5 from the main processor 27 to a second or third random code H2, H3 (which are changed on each new openmg signal S3, S5, and consequently also the code between the control unit 3 and the motor-lock 4 is protected against readmg and repetition to achieve unlawful openmg of the motor-lock 4 in the manner desc ⁇ bed in greater detail below), for forwarding via the cable 6 to the motor- lock 4 following completed and approved ve ⁇ fic
- the motor-lock 4 comprises a receiver in the form of an activation circuit card 32 for the random codes H2, H3 from the control unit 3.
- the motor-lock 4 is connected via a connector 33 by means of electric cable 6 to the control unit 3 and to an external power source, which can consist of both an alternating current and a direct current source, the motor-lock 4 being disposed to set itself automatically to different voltages in the voltage ranges normal for motor-locks 4.

- the box 37 and cover of the lock compartment 13 include openings 42, 43, for cabling purposes and for a cylinder or handle follower 44, 45, which forms part of each lock mechanism.
- the motor-lock 4 shown in Figures 3 to 5 comprises two locking mechanisms, which consist of a motor-lock mechanism 46, which has an electric motor 47 for retraction and extension of the linearly movable latch bolt 14, and a conventional rotary lock mechanism 48.

- One or more springs 53, 54 are arranged inside the lock compartment 13, which springs 53, 54 lie close to the spring bolt 41 and the carrier arm 50 under tension, the springs 53, 54 being provided to hold the spring bolt 41 normally in a position partly projected outside the lock compartment 13, until the handle or knob 49 is used.
- the spring bolt 41 ensures that the door panel 9 and thereby the latch bolt 14 end up in the right position before the electric motor 47 is started.
- a door closer not shown, can also be provided suitably on the door 8 for closing it, following which also said magnets 31 and magnetic sensors 30 detect that the correct position has been assumed.
- At least one further magnetic sensor 31 and magnet 30 are fitted in the lock compartment 13 and on the spring bolt 41 for detecting the position of the spring bolt 41, i.e. whether it is in its projected or retracted position, which positions provide two of the sub-signals SSI, SS2 etc., which the microprocessor 36 is set to collect and transmit to the control unit 3.
- the motor-lock mechanism 46 comprises an operating device 55 for interaction with the electric motor 47 for said retraction and extension of the latch bolt 14.
- the operating device 55 comprises an oblong, linearly movable earner 56, which has an essentially rectangular cross-section.
- the carrier 56 has a rectilinear cog rail in the form of a rack 57 disposed at its one end and an oblong, continuous recess 58 disposed at its opposite, other end.
- a cogwheel 59 is mounted on the revolving axle 60 of the electric motor 47 for bearing on the cog rail 57 for said retraction and extension of the linearly movable latch bolt 14.
- the carrier 56 also comprises a cog segment 61 and two hooks 62, 63 arranged on opposing sides of the recess end 58 of the earner 56, where the two hooks 62, 63, which are ananged at a set distance from one another, are turned towards the cylinder follower 44 to engage with a peg 64 raised from the follower 44, turning of the cylinder follower 44, via its knob or via a traditional lockmg cylmder by means of a mam key, offering an opportunity for manual openmg of the motor- lock 4, for example in an emergency situation or if the power supply is interrupted
- the earner 56 also has two level sliding surfaces 65, which are at ⁇ ght angles to the two sides which comp ⁇ se said cog segment 61 and hooks 62, 63, one of which sliding surfaces 65 extends from the cog rail 57 to the end of the recess end 58 and the other, not shown, extends the whole of the carrier's 56 longitudinal extension on the opposite side in relation to the co
- An oblong blocking arm 66 is ananged rotatably at one of its ends by a semicircular cog segment 67 on a pivot 68
- the cog segment 61 of the earner 56 extends m the longitudinal direction of the earner 56 and has a length which corresponds to at least the peripheral length of the essentially semicircular cog segment 67 of the blockmg arm 66
- the pivot 68 is arranged to the side of the carrier 56 and at such a distance from it that on activation of the electric motor 47, the two cog segments 61, 67 interact with one another m a movement which is linear for the earner 56 and rotational for the blocking arm 66
- the blocking arm 66 has a earner pin 69, which is inserted mto an essentially tnangular recess 70 m the rear part of the latch bolt 14, termed the operating part 71 below, while the front part of the latch bolt 14 is termed the engagement part 72
- the engagement part 72 On the turning movement forwards and backwards
- the blocking arm 66 is provided to block the projected latch bolt 14, which blocking arm 66 withstands the pressure of 500 kg (applied to the latch bolt 14) required for approval by the insurance companies. A further "night lock", i.e. a manual locking mechanism with a manually operated latch bolt, is thus not needed.
- the blocking arm 66 comp ⁇ ses a locking surface 75 ananged at the front end of the blocking arm 66 of the latch bolt 14, which locking surface 75 is provided to bear on and interact with a stop ledge 76 in the projected position of the latch bolt 14, see Figure 3.
- the stop ledge 14 is disposed by the engagement part 72 of the latch bolt 14, more precisely by its rear part 74, the stop ledge 76 and locking surface 75 being arranged parallel to one another in said projected position of the latch bolt 14.
- the lock 4 By providing the lock construction with sensors, for example magnetic sensors 30, and a control unit 3 which verifies that the motor-lock 4 is in the correct position before the electric motor 47 is activated, in which case the latch bolt 14 does not have to align the door panel 9 in relation to the recess for the latch bolt 14, which calls for a strong motor 47 which presses the bolt 14 into the recess 12 even if the door panel 9 is in any open position, the lock 4 according to the invention can have an electric motor 47 model which is smaller, creating extra space inside the lock compartment 13.
- reinforcement plates 77 Disposed inside the lock compartment 13 are a number of reinforcement plates 77 in the form of thin metal plates, which reinforcement plates 77 have each been cut very precisely with regard to cross-section and with varying extension in the plane to fit according to the construction elements to be found inside the lock compartment 13.
- the reinforcement plates 77 are placed on top of and at a set distance adjacent to one another to form channels and spaces 78 for components of the motor-lock 4 and cables 6 and to fill up essentially the rest of all the empty space inside the lock compartment 13, or to fill one or more defined parts of the lock compartment 13 to thereby increase the resistance capacity over essentially the entire lock compartment 13, or here and there in specially selected places, against external damage by means for example of breaking, drilling or striking tools.
- a number of pins 79 extend between the box 37 of the lock compartment 13 and its cover, for which pins 79 a number of holes 80 have been made through the reinforcement plates 77.
- the main processor 27 is preprogrammed together with said activation circuit cards 23, 26, 29, 32, which preprogramming is carried out initially by the necessary data being transmitted between the activation circuit cards 23, 26, 29, 32 forming part of the locking system 1 and the main processor 27.
- Fig. 6 shows diagrammatically by means of a flow chart a method according to the present invention for opening of the motor-lock 4 belonging to the locking system 1 described above for controlling in and out passage to or from a certain room or area, preferably a building or an enclosure, via an automatic door system.
- the procedure is initiated by a user, via the registration device 16 on the operating panel 2 outside said room or area, registering his defined and unique authorization code Bl, which consists of one of several approved authorization codes Bl, B2, B3 etc. stored previously in the memory 28 of the control unit 3. If the registration device 16 consists of a card reader, registration is effected for example by an information ca ier 17 being guided through the card slot 20 of the card reader 16 to read said code Bl, or the cunent authorization code Bl is entered manually via the key set 18 of the operating panel 2.
- a first signal SI containing the read or entered authorization code Bl is generated, which first signal SI is transmitted to the activation circuit card 23, where a random number generator 25 is activated, so that a binary number of a set length is generated, which number varies randomly each time the activation card 23 is activated by said first signal SI .
- the signal converter 24 of the activation circuit card 23, for example a microprocessor, converts by means of a predetermined numerical calculation the first signal SI and the binary random number to a new and second signal S2, namely the above so-called "random" code HI, which code HI is thus changed randomly for each activation event, thanks to the effect of the random number generator 25 on the calculation.
- the random code HI is then transmitted via cable 5 to the control unit 3 situated at a distance from the operating panel 2, which unit consists of a personal computer, an advanced microprocessor or similar.
- the electric cable 5 does not need to be protected against reading, since the random code HI is always both coded and changed between each attempt to open the door, regardless of whether an inconect or co ⁇ ect authorization code Bl was originally used.
- the random code HI is received by the receiver 26 of the control unit 3, i.e. the second activation circuit, where it is decoded and then transmitted to the main processor 27.
- the thus recreated authorization code Bl is compared with the database stored in the memory 28 to verify whether the random code HI received is a calculation result which is based on and agrees with one of the authorization codes Bl, B2, B3 etc. stored in the memory 28 and, if such a one is found, that it has approved the authorization for the current motor-lock 4.
- a first opening signal S3 which either consists of the originally received authorization code Bl or a new such code B2, is sent to the transmitter of the control unit 3, i.e. its third activation circuit card 29, which performs a new numerical calculation based on the opening signal S3 and a new binary random number, so that a new, second random code H2 is generated, which is transmitted via cable 6 to the motor-lock 4.
- this cable 6 does not need to be shielded or protected either against reading of this, now second, random code H2.
- the second random code H2 is received by the receiver 32 of the motor-lock 4, i.e. the fourth activation circuit card of the locking system 1, which activation circuit card 32 verifies that the incoming random code H2 has the correct authorization, which is earned out in the same way as at the receiving activation circuit card 26 of the control unit 3.
- the motor-lock 4 sends back a fourth signal S4 to the main processor 27 of the control unit 3, which signal S4 is first combined with several of the sub-signals SSI, SS2, SS3 etc., which together describe the current status of the motor-lock 4 with regard to desired and/or necessary information about the current settings and state of the motor-lock 4.
- the magnetic sensors 30 and the magnets 31 it is detected by means of the magnetic sensors 30 and the magnets 31 whether the spring bolt 41 or the latch bolt 14 are projected or retracted, whether the latch bolt 14 has been locked by means of the blockmg arm 66 or not (detected by a sensor not shown), whether the movement of the latch bolt 14 is blocked m any direction, so that the electric motor 47 after three closing attempts contmues to be prevented from pushing the latch bolt 14 mto the recess 12, following which an alarm is tnggered, whether the door panel 9 is in the open or closed position, which is simply registered by means of magnets 31 and magnetic sensors 30 arranged on the door panel 9 and on the door frame 10, etc
- the combined signal S4 is uncoded in the embodiment described, but can if necessary easily be converted to a random signal by means of a further activation circuit card disposed inside the motor-lock 4
- the combmed signal S4 is received by the main processor 27 of the control unit 3, processed by this and if all sub-signals SSI, SS2 etc are conectfor door openmg, a second opening signal S5 is sent anew to the transmitter 29 of the control unit 3, coded to give a new random code H3, which is transmitted to the motor-lock 4 via cable 6 This time the electric motor 47 of the motor-lock 4 is activated in a direction of rotation which retracts the latch bolt 14
- the function for instead placing the motor-lock 4 m the lockmg position is executed in a similar manner by means of an authonzation code Bl, by means of a timer, which triggers locking, via a circuit-breaker inside the protected area or room, for example at the control unit 3, or by means of mechanical projection of the latch bolt 4 by means of a key or knob
- the latch bolt 14 should be braked softly pnor to its two end positions, l e bolt out/bolt in Braking is effected preferably by short-circuiting the motor winding and thereby giving the motor 47 the same function as a generator, which means that the desired effect, efficient deceleration, is achieved Damage of the type described above can likewise occur in connection with openmg/ closing the lock 4 via key or knob 49 This applies both before and after the lock 4 has been connected to a power source In new buildings under construction, electric locks 4 are often used as a mechanical lock until elect ⁇ cal cables 6 are laid This means that even before the lock 4 is connected to the power, the electric motor 47 should be short-circuited to thereby keep its braking function
- the invention is not restricted to the embodiment shown, but can be vaned in different ways within the framework of the claims It is perceived for example that the measures taken and arrangements made to obtain considerably improved protection against break-m, namely the reinforcement plates 77, blocking arm 66 and the fact that the authorization code Bl and all other essential signals S2, S3, S5 in the system outside the protective envelope of the main components always consist of a random code HI, H2, H3, are applicable m a locking system essentially compnsmg an unlimited number of motor-locks, and that these motor-locks can be formed in different ways with regard to the requirements for standardized dimensions, the number of lockmg mechanisms and which closmg device they are arranged on
- braking mechanisms other than the motor winding can be used to avoid any damage to the motor axle/power transmission, such as mechanical braking devices which take effect close to the respective end position.
- means other than magnetism e.g. optical sensors, can be used to detect that the door is in the correct position to be able to be locked.
- many of the new functions described in the lock can be utilized in themselves without necessarily being combined with all the other functions described, e.g. it is not necessary to use random codes to exploit the advantages of the new combination of having a fast, smaller motor/ transmission and a mechanism which detects that the door panel is in the conect position, so that the latch bolt can move into the recess quickly and without difficulty.
