Definitions

  • the present invention relates to a device for actuating a security lock with a movable bolt operated by two handles intended to be arranged on either side of a door and rotating around separate axes substantially parallel between a closed position and an open position, this device comprising a declutching mechanism intended to be mounted between these handles and an electrical system making it possible to bring this mechanism either in a disengaged state or in a engaged state, the first handle being able to cooperate directly with the bolt , the second handle being able to cooperate with the latter via the declutching mechanism.
  • One of the essential aims of the present invention is to present a device of the aforementioned type of an extremely simple and reliable construction which can, if necessary, be mounted on any type of traditional lock with movable bolt, in particular barely half-turn able to move against a spring under the action of one of the handles, between a closed position, in which the bolt is engaged in a keeper provided in a frame, and an open position, in which the bolt is withdrawn in the strike against this spring.
  • movable bolt in fact any bolt which can move without a key in the lock, that is to say by the action of a handle or a spring, unlike d '' a deadbolt which generally requires the use of a key to bring it from one position to another.
  • handle capable of cooperating directly with the bolt it is understood to mean a handle which makes it possible to control the bolt independently of the declutching mechanism, possibly by means of a system of transmission, such as for example a lever acting directly from the handle on the bolt.
  • a system of transmission such as for example a lever acting directly from the handle on the bolt.
  • the present invention therefore relates to a device which can actuate both a security lock with a bolt and several movable bolts distant.
  • the aforementioned disengaging mechanism comprises a first transmission member which can be actuated by the first handle in a rotational movement around its aforementioned axis, a second transmission member rotating around the aforementioned axis of this second handle, a connecting rod connecting the two transmissioin members in places located outside the axes of rotation of the latter, and means, controlled by the electrical system, on the one hand, to create with the connecting rod, in the above-mentioned engaged state, a rigid link between the two transmission members during an angular displacement of said second transmission member in at least one determined direction around the axis of rotation of the latter, so as to subject the first transmission member also to an angular displacement, and, on the other hand, to break, in the above disengaged state, this rigid link, so as to at least partially release the second member of tr ansmission relative to the first and thus allow an angular displacement of the second organ substantially independently of the first organ.
  • the connecting rod is formed from two separate coaxial parts which can cooperate with each other, one of the parts being articulated on the first transmission member, the other part on the second transmission member, the aforementioned means comprising a movable blocking member controlled by the electrical system, and cooperating with the connecting rod, this blocking member being arranged so as to allow, on the one hand, a relative displacement of these two parts in the aforementioned disengaged state during an angular displacement of the second member transmission around the axis of rotation of the latter, and, on the other hand, to prevent this relative displacement in the engaged state at least during an angular displacement of this second member in the aforementioned determined direction around this axis.
  • one of the two parts is constituted by a piston, the other by a cylinder in which this piston can slide, the blocking member being formed by a retractable stopper which, at the 'engaged state, is engaged through the cylinder, on the sliding path of the piston, so as to form a support for the latter during an angular displacement of the second member in the direction determined above, and which, in the state disengaged, is released relative to this sliding path.
  • the invention also relates to a security lock provided with such a device.
  • This lock is more particularly characterized by the fact that it comprises a first handle cooperating directly with the movable bolt and a second handle cooperating with this penalty by means of the declutching mechanism, the latter being arranged on the same side as the first handle relative to the bolt, a first transmission member being wedged on a first shaft on which the first handle is fixed and extending along the axis of rotation of the latter, a second transmission member being wedged on a second shaft on which the second handle is fixed, the aforementioned declutching mechanism being mounted between these two transmission members, so as to make it possible to rotate, when the declutching mechanism is in the engaged state, the first shaft around its axis of rotation and bring the bolt in its open position during an angular displacement of the second handle, and activate the bolt by means of the first handle, independently nt the state in which the declutching mechanism is located.
  • the invention also relates to a door provided with such a security lock.
  • the particular embodiment of the security lock according to the invention as shown in the various aforementioned figures comprises a housing 1 in which is arranged a movable bolt, in particular a latch bolt 2, which can be operated by two handles 3 and 4 , located on either side of a door 5, against a leaf spring 30.
  • the first handle 3 cooperates directly with the bolt 2, while the second handle 4 cooperates with the latter via a declutching mechanism 6.
  • This clutch release mechanism 6 comprises a first transmission member 7, formed by an eccentric wedged on a first square shaft 8 by means of a screw 9, a second transmission member 10, also formed by an eccentric wedged on a square shaft 11 by means of a screw 12, a connecting rod 13 connecting the two transmission members 7 and 10 at points, respectively 14 and 15, located outside the axes of the shafts 8 and 11 and means 16, controlled by an electrical system 17, on the one hand, to create with the connecting rod 13, in the engaged state of the mechanism 6, a rigid link between the members 7 and 10 during an angular displacement of the member 10, according to the direction indicated by the arrow 18, around the axis of the shaft 11, so as to subject the member 7 also to an angular displacement in the same direction, as indicated by the arrow 18 ⁇ , and, on the other hand, to break, in the disengaged state of mechanism 6, this link rigid, so as to release the second transmission member 10 relative to the first and thus allow an angular displacement of the latter substantially independently of the first member 7.
  • the connecting rod 13 is formed of two separate coaxial parts 19 and 20 which can cooperate with each other.
  • the part 19 is articulated at point 14 on the eccentric 7, while the part 20 is articulated at point 15 on the eccentric 10.
  • the aforementioned means 16 comprise a blocking member 21 controlled by the electrical system 17 and cooperating with the connecting rod 13.
  • This blocking member 21 is arranged, so as to allow, on the one hand, to move these two parts 19 and 20, one with respect to the other during the angular displacement of the eccentric 10 around its axis of rotation with the mechanism 6 in the disengaged state, and, on the other hand, to prevent the relative displacement of these two parts 19 and 20 in the engaged state of the mechanism 6, at least during the angular displacement of the eccentric 10 in the direction of the arrow 18.
  • the part 19 is constituted by a cylinder and the other part 20 by a piston sliding in this cylinder, while the locking member 21 is formed by a retractable stopper which, at the the engaged state of the mechanism 6, is engaged through an orifice 31 provided in the side wall of the cylinder, as shown in FIG. 5, on the sliding path 32 of the piston 20, so as to thus form a support for the latter during an angular displacement of the eccentric 10 in the direction of the arrow 18, and which, in the disengaged state of the mechanism 6, is released relative to this sliding path, as shown in FIGS. 2 to 4.
  • the stopper 21 is fixed on a core 33 of an induction coil 22 which can move axially in this coil, when the latter is excited via the electrical system 17, so as to bring the stopper 21, by the orifice 31 of the cylinder 19 through the sliding path 32 of the piston 20.
  • the induction coil 22 is mounted on a support 34 which is itself fixed on the part 19 forming the cylinder, so as to be able to move with the latter during a rotation of the eccentric 7 around the axis of the shaft 8.
  • the eccentric 10 cooperates with a return spring 24 which makes it possible to return or maintain this eccentric in a rest position against a first end-of-travel stop 25, corresponding to the closed position of the bolt. From this position, the eccentric 10 can undergo an angular displacement in the direction of the arrow 18 and, when the mechanism 6 is in the engaged state, as shown in FIG. 5, act through the connecting rod 13 on the eccentric 7 to subject the latter to a corresponding angular displacement around the axis of the shaft 8.
  • a second end-of-travel stop 26 is provided to limit this angular displacement of the eccentric 10 in the direction of the arrow 18, as shown in FIG. 4, and above all to, as also the stop 25, prevent the piston 20 to come out of the cylinder 19. This could in fact occur during an excessive angular displacement of the eccentric 10.
  • a control 28 of the electrical system 17 can be mounted on this plate 27 which makes it possible to activate the induction coil 22 and thus bring the mechanism 6 into the engaged state.
  • This command comprises a keyboard 29 formed for example of nine keys each corresponding to a number from 1 to 9.
  • a timer is incorporated in the electrical system which makes it possible to maintain the mechanism 6 in the engaged state only for a limited period from the moment when the code has been entered.
  • the protective plate 27 as well as the keyboard 29 are arranged in a lining 35 which can also wrap a part of the components of the electrical system, the essential elements of the latter however preferably being mounted on the opposite side of the case 1 of the lock.
  • FIG. 2 shows the lock with the bolt 2 in the extended position, that is to say in the closed position under the action of the leaf spring 30, and the mechanism 6 in the disengaged position, that is to say with the stopper 21 in the withdrawn position relative to the sliding path 32 of the piston 20 in the cylinder 19.
  • the handle 3 can bring the bolt 2, against the spring 30, into an open position, as shown in FIG. 3, by rotating the latter in the direction of the arrow 18 ⁇ around the axis of the shaft 8 on which it is fixed since the piston 20 slides freely in the cylinder 19, the handle 4 is therefore not applied when the handle 3 is actuated.
  • the two angular displacements of the handles 3 and 4 are, for the embodiment shown in the figures, identical, since the distances which separate the articulation points 14 and 15 from the axis of rotation of the shaft 8, respectively 11, are also identical.
  • the bolt 2 can be brought into its open position by rotating the handle 4 around the axis of its shaft 11.
  • the handle 3 and the declutching mechanism 6 are located on the side of the enclosure to be protected.
  • the declutching mechanism 6 is preferably mounted as a surface against the door, on the side of this enclosure, while the protective plate 27, which is therefore on the opposite side of the door, is held in place by screws or bolts, not shown, which are accessible only from the side of the handle, that is to say from the enclosure to be protected when the door is closed.
  • This last variant of the electrical system could for example be envisaged in a counter room of a bank or a post office which would allow an employee to engage the mechanism 6 when he wishes to give access to a customer appearing before a glass door separating the offices from the room for the public.
  • the electrical system could be designed to engage the mechanism 6 by cutting off the excitation current from the coil 22.
  • transmission members 7 and 10 could also be very different. These members could, for example, be formed by simple levers rotating around the axis of the corresponding handle, which also could be of any design.
  • the device according to the invention allows the production of a lock which is at the same time "anti-panic” and inviolable.
  • the lock can be actuated exactly like a normal lock and always allows the door to be opened, regardless of the position of the disengaging mechanism, even if it is on the other side, on the opposite side of the door, the lock automatically returns to a safe or inviolable state after the door has been closed and this without any particular intervention being necessary.
  • At least one of the handles 3 or 4 fixed on the lock could be replaced by a removable key which can engage in a hole in the lock and which makes it possible to actuate the corresponding transmission member 7 or 10.
  • the handles 3 or 4 are in fact constituted by these keys. It would mainly be the handle 4 located on the outside of the room to be protected. This would in a way form a double protection.
