Definitions

  • the present invention relates to a reversible electric lock particularly of the type suitable for installation in fire doors.
  • a fire door which meets the requirements of the standard must be subjected to a series of tests, at the end of which it receives a type approval (homologation) which ensures its compliance with the prescribed requirements.
  • type approval homologation
  • any change made to the door entails loss of type approval.
  • fire doors have respective versions which correspond to either opening direction, each of which has its own type approval.
  • the aim of the present invention is to provide a reversible electric lock which allows complete reversibility of the door in which it is installed without any structural modification and without any external intervention for selection.
  • an object of the present invention is to provide a reversible electric lock which has a low cost, is relatively simple to provide in practice and safe in application.
  • This aim and this object, as well as others which will become better apparent hereinafter, are achieved by the present reversible electric lock, of the type comprising at least one pair of electromechanical actuators, which are connected to a respective power supply circuit and are interposed between at least one element for locking the door in the closed configuration and at least one handle passage which can rotate by actuation of said handle, and at least one seat for a cylinder which is functionally associated with means for retracting the at least one element for locking the door in the closed configuration, characterized in that it comprises at least one sensor which is meant to detect, even indirectly, the presence of said cylinder in at least one respective seat of said lock, said sensor being controlled by an electric switch for connecting alternatively to an external power source one of the two power supply circuits of said electromechanical actuators.

  • Figure 7 is a perspective view of a lock according to the invention in a possible fitting configuration
  • Figure 8 is an enlarged-scale view of the detail VIII of Figure 7. Ways of carrying out the invention
  • a reversible electric lock is generally designated by the reference numeral 1.
  • the lock 1 comprises at least one pair of electromechanical actuators 2, which are connected to a respective power supply circuit 3.
  • the actuators 2 can be constituted by small electromagnets, in which the moving element is movable from a retracted configuration, in which it does not interfere with other parts of the lock 1, to an extracted configuration, in which it interferes to lock at least one element
  • the element 4 is the latch of the lock 1, which, by protruding with respect to the front surface 5 thereof, interferes with a corresponding selvage provided on the jamb, ensuring that the door is retained in the closed configuration.
  • the elements 4 comprise a plurality of latches and/or bolts in order to maximize the safety of said door against break-in attempts.
  • the actuators 2 are interposed between the element 4 and at least one handle passage 6, which can rotate by way of the action of said handle (the shank of which is accommodated within a central slot 7 of the passage 6): in this manner, the handle is correctly coupled to the element 4 only when the respective actuator 2 releases said element 4, allowing its retraction. In all other cases, the rotation of the handle does not entail the retraction of the element 4, since said element is kept in the extracted configuration by way of the action of the actuator 2.
  • the lock 1 further comprises at least one seat 8 for a cylinder 9, which is functionally associated with means 10 for retracting the element 4.
  • the cylinder acts on the retraction means 10 by means of a bit 11 of its own, moving said means from an inactive configuration (element 4 which protrudes with interference with the selvage of the door jamb) to an active configuration (by forcing suitable elastic means 12), in which the element 4 is retracted into the lock 1.
  • the lock 1 comprises at least one sensor designed to detect the presence of the cylinder 9 in at least one respective seat 8.
  • the sensor is controlled by an electric switch for connecting alternatively to an external power source 13 one of the two power supply circuits 3 of the electromechanical actuators 2.
  • the sensor is a microswitch 14, which has an actuation lamina 15 which faces and is proximate to a seat 8 for the insertion of the cylinder 9.
  • the lamina 15 is free and flexed outward when the seat 8 which it faces is empty (it accommodates no cylinder 9); the lamina 15 is instead compressed, resting against the surface of the outer body of the microswitch 14, when the reference seat accommodates the cylinder 9. This occurs due to the forcing of said lamina 15 into said configuration by the cylinder 9 or by apparatuses connected thereto or associated therewith.
  • the microswitch 14 maintains the electrical connection between the source 13 and a second circuit 3b, which is associated with an actuator 2b when the cylinder is not inserted in the seat 8 which the microswitch 14 faces, and does not supply a first circuit 3 a; when instead the cylinder 9 is inserted in the seat 8, the microswitch 14 diverts the connection of the source 13 on the first circuit 3 a, interrupting the power supply of the second circuit 3b.
  • a lock 1 which comprises two microswitches 14, each of which is installed proximate to a respective seat 8 for the insertion of the cylinder 9 to detect the presence of the respective cylinder in said seat.
  • both the first circuit 3 a and the second circuit 3 b are normally open (not connected to the source 13); the insertion of the cylinder 9 in either seat 8 ensures the closure of the respective circuit (3 a or 3b), consequently supplying power to the respective actuator (2a or 2b).
  • the senor is a gravity contactor, which is constituted by an assembly provided with an internal cavity for accommodating a conducting body.
  • the cavity is provided with a pair of circuits, an upper one at a lower one, each of which is associated with a respective actuator (2a and 2b, and therefore the circuits correspond to the circuits designated by the reference numerals 3a and 3b in the previously described embodiment), which are interrupted at said cavity.
  • the electrical continuity of either circuit is determined by the presence of the conducting body on one of the upper and lower faces of the cavity as a consequence of the fitting of the lock in one of the possible opening directions of the installation door.
  • the electric circuit which corresponds to a specific actuator 2a (or 2b) closes across the conducting body which, depending on the orientation of the lock, rests against the upper or lower face of the cavity.
  • a mercury switch in which the conducting body is constituted by a preset quantity of mercury, which by being free to move within the cavity according to the force of gravity, constitutes an electrical bridge for the terminals of the circuit that it affects when it is on the upper face or on the lower face.
  • the senor comprises, at least one seat 8 for accommodating the cylinder 9, two electrical contact terminals of a power supply circuit 3a (or 3b) of an actuator 2a (or 2b), which face the edge and protrude toward the inside of said seat 8.
  • the cylinder 9, when it is inserted in the seat 8, constitutes an electrical bridge between the two terminals, with consequent electrical continuity of the circuit 3 a (or 3b) associated therewith, consequently supplying power to the actuator 2a (or 2b).
  • the activation of the sensors is achieved by means of at least one of the elements for fixing the cylinder 9 in the lock 1 : in particular, it should be noted that the lock 1 comprises a front hole 16, which is aligned with the fixing hole provided in the cylinder 9; therefore, it is possible to insert within said hole 16 a screw 17 for fixing the cylinder 9, the tip of which can act on the sensor, causing its activation.
  • the sensor and the respective electric switch must be connected upstream to the external power source 13 and downstream to both circuits 3a and 3b for supplying power to the actuators 2a and 2b.
  • the switch When the sensor detects the presence of the cylinder 9 in the respective seat 8, the switch provides electrical continuity between the power source 13 and the first circuit 3 a; when the sensor does not detect the presence of the cylinder 9 in the respective seat 8, the switch provides electrical continuity between the power source 13 and the second circuit 3b. If instead the sensors (and the respective switches) are at least two, each one at a respective seat 8a and/or 8b for a cylinder 9, the sensors must be provided with a respective electric switch and must be connected upstream to the external power source 13 and downstream to the respective power supply circuit 3 a of the actuator 2a.
  • the first switch When the first sensor detects the presence of the cylinder 9 in the first seat 8a, the first switch provides electrical continuity between the power source 13 and the first circuit 3 a.
  • the second switch When the second sensor detects the presence of the cylinder 9 in the second seat 8b, the second switch provides electrical continuity between the power source 13 and the second circuit 3b.
  • the insertion of the cylinder 9 in one of the seats 8 provided in the lock 1 and its fixing entail the activation of only one of the two actuators 2a and 2b, the one that corresponds to the seat 8a or 8b in which the cylinder 9 is located.
  • each sensor is preset for the electrical connection of the corresponding circuit 3 a (or 3b) to the source 13.
  • the constructive choice which provides for the presence of a gravity contactor does not require direct detection of the presence of the cylinder 9 in the seat 8a or in the other seat 8b; this information is derived directly from the fact that a particular fitting configuration of the lock 1 is necessarily associated with the insertion of the cylinder 8 in only one of the seats 8a or 8b. It has thus been shown that the invention achieves the intended aim and objects.
