Definitions

  • This invention relates to a central locking system according to the preamble of claim 1.
  • the aim of the invention is to achieve a new, constructionally uncomplicated central locking system, advantageous as to its costs and simple to assemble and which is particularly suited to an office environment, in order to provide central locking and unlocking of different items such as the doors and locks of cupboards, chests of drawers and other storage units and also the locks of furniture, data processing and storage means etc.
  • the aim of the system that it should be easy to install even afterwards.
  • each drive means is an electric motor
  • the control unit not only switches the current to the motors on and off but also chooses the direction of current flow to the motors depending on whether movement is to be into a locking or an open position
  • the system includes an accumulator unit for connecting the system to a power source, for instance to the mains, and for increasing the current strength to the motors momentarily when current is connected by said selecting member.
  • the control unit includes a locking mechanism, it is not necessary to limit entry to the place where the system is installed.
  • the bolt members of the locking units do not require much power and so quite small electric motors can be used.
  • the system includes a rather large number of locking units, use of the accumulator will provide the momentary power required to effect locking or unlocking. It is not necessary to have the system continuously connected to the mains and because the voltages used are low, the system does not need special attention paid to insulation. This makes the system economical and easy to assemble.
  • the locking mechanism used is a key-operated rotatable locking disk cylinder lock.
  • said selecting member is installed on a force transmission member connected to the locking mechanism so that turning of the selecting member into a position allowing power to be switched on to open the locking units is not possible until the cylinder mechanism is turned by its key to the open position.
  • the disk cylinder lock could be used a conventional bi-directionally operable rotatable locking disk mechanism such as is described in Patent FI-74320.
  • the disk cylinder lock comprises a rotatable locking disk mechanism operable in one direction in a way known as such, in which is a lock housing containing a rotatable inner cylinder and locking bar, which is in part located in a groove in the inner surface of the lock housing when the mechanism is in the locked state.
  • the selecting member can move in the opposite direction to the operating direction of the lock mechanism the groove is extended in that opposite direction.
  • a switch member can be connected to the selecting member, having a neutral position, when current is not connected and, on each side of this neutral position, extreme positions when power is connected to the locking units. It is an advantage to choose a switch member in which turning the switch member from one extreme position to the other changes the direction of the current flow at the same time. In this way the electric motors can simply be operated by the same switch member for providing both locking and unlocking.
  • This switch member can with advantage, be fastened to the lock housing of the locking mechanism.
  • the switch member is loaded to return from either of the extreme positions to the neutral position. If in addition the said selecting member is spring loaded in the neutral position, in which it does not affect the switch member it will ensure that the locking units circuit is only closed when one actually wants to either open or close the locks. In this way, in practice, the accumulator unit will always have plenty of time to become charged so as to accomplish said operations.
  • Each locking unit can include a lock body enclosing a rotary electric motor, and is provided with limiting members to limit, in either turning direction, the turning movement of the spindle of the electric motor and the guiding member attached thereto and acting on the bolt member. In this way all movements of the bolt member can be simply achieved by the electric motor.
  • the accumulator unit can with advantage include a number of capacitors connected in parallel.
  • the electric motors for use in such locking units should be in the nominal power range 1 to 15 volts, and preferably 3 to 12 volts.
  • reference numeral 1 indicates a control lock for a central locking system.
  • the control lock can be a cylinder lock of ordinary construction, preferably provided with rotatable locking discs, the locking mechanism of which being turnable on either side of the insertion position of the key (not shown in the drawings) at least for some distance. Opening of the locking units takes place by turning the key in the control lock in the direction A and locking thereof by turning the key in the direction B respectively.
  • Control of the operation of the locking units is provided electrically, and for this purpose the system includes an accumulator unit 4 and a transformer 5, through which the system is connected to the mains network.
  • the control lock includes three light diodes to indicate the state of operation of the control lock and of the system.
  • Light diode 7 burns when the switch members (cf. figure 2) of the control lock are switched so as to be connected to the voltage.
  • Light diode 8 burns when the locking units 2a-2n are moved into the opening position, and light diode 9 burns when the locking units 2a-2n are moved into the locking position.
  • FIG 2 An electric circuit diagram for the central locking system is disclosed in figure 2.
  • An essential component for the control of electric motors 12 in the locking units 2a-2n is a switch 6, to be operated by the control lock 1 and having a neutral position, into which it is mechanically urged to move and in which there is no current connected to the locking units.
  • the switch 6 In the position shown in figure 2 the switch 6 is in its neutral position.
  • the switch 6 has an operating position on either side of the neutral position for controlling the operation of the locking units 2a-2n.
  • the switch 6 When the switch 6 is turned by means of the control lock 1 from its neutral position to the operation position corresponding to opening of the locking units, in other words in accordance with figure 1 in the clockwise direction A, the switch 6 connects the poles 28/29 and 31/32. Then the electric motors 12 rotate in a direction, in which they are arranged to allow movement of the bolt members 3 into the position in which the locking is released. Correspondingly, when the switch 6 is turned into a position, in which it connects the poles 29/30 and 32/33, the direction of the current is changed and, due to the electric motors 12, the bolt members 3 move into the locking position thereof.
  • the accumulator unit 4 comprises a number of capacitors 10 connected in parallel and the capacitance of which can be for instance in the order of 0,04 F.
  • the system can without difficulties include over 20 locking units, for the accumulator unit provides a momentarily high current peak for operating the electric motors of the locking units.
  • Due to the accumulator unit it is also possible to use high overvoltages in the system, whereby increased power can be obtained from the electric motors in comparison with when their nominal voltage would be used.
  • undisturbed operation of the bolt members of the locking units can be secured.
  • the overvoltage is only momentary, the electric motors cannot get damaged irrespective of the fact that the rotational movement thereof is limited by stationary limiting members (cf. limiting members 26 in figure 6).
  • FIG. 3 shows the control lock 1 viewed from the back side thereof.
  • a force transmission member 13 attached to the locking mechanism of the control lock is arranged to turn a selecting member 14, which includes guiding members 15 and 16 acting on the switch 6.
  • the selecting member 14 is turned by the key of the control lock, either one of the guiding members 15 or 16 presses the switch 6 into a position in which the current of the locking units closes thereby starting the electric motors 12.
  • the bolt members 3 of the locking units move either into the looking or into the opening position thereof.
  • the selecting member 14 turns under the influence of a spring 17 back towards its initial position away from the reach of the switch 6. Thereby, also the switch 6 is free to move back into its neutral position, into which it is urged to move, whereby current is switched off.
  • the control lock 1 can be a conventional bi-directionally operable cylinder lock provided with rotatable looking discs.
  • a corresponding cylinder lock operating only in one turning direction can with advantage be applied for the purpose as well, for instance when modified in a way as disclosed in figure 4.
  • the look of figure 4 corresponds to that shown in figure 3, but the selecting member 14 and the switch 6 have been removed.
  • a groove 21 in the lock housing 18, provided for locking bar 20 included in a conventional looking mechanism based on rotatable locking discs, has been enlarged into the direction opposite to the normal operation direction of the locking mechanism so that an inner cylinder 19 and the force transmission member 13 attached thereto can be turned from the initial position of the key, or from the insertion position thereof, into said direction a distance so as to enable the switch 6, due to the selecting member 14 attached to the force transmission member 13, to connect current into the electric motors 12 in the locking units so as to provide locking. Otherwise the operation of the locking mechanism is fully conventional.
  • the arrows A and B in figure 4 correspond to those shown in figure 1.
  • Figure 4 also shows a slot 22 provided with stop surfaces 23 arranged in the lock body for a return spring 17 arranged to urge the selecting member 14 into a position corresponding to the neutral position of the switch 6.
  • Figure 5 shows an embodiment of the locking unit 2, which is provided with two steel balls serving as bolt members 3 arranged to be pressed into a protruding position for providing locking by a guiding member 24, which is fixed to the spindle of the electric motor 12 by means of a screw 25.
  • a guiding member 24 is turned in the other turning direction, whereby the electric motor 12 rotates in the opposite direction, the guiding member 24 allows the bolt members 3 to move inside the lock body into the releasing position.
  • Figure 6 shows the cross-sectional form of the guiding member 24 as well as the limiting members 26 made in the lock body and determining the freedom of rotation allowed for the guiding member 24 and, thus, for the electric motor 12.
  • FIG. 7 shows an alternative embodiment for the locking unit 2, in which a conventional turnable cam member 27 serves as the bolt member.
