Definitions

  • the present invention relates to a device for actuating a movable bolt security lock operated by two handles, the latter being arranged on either side of a door and rotating around separate axes which are substantially parallel, between a position of closing and an open position, a disengagement and clutch mechanism being mounted between these handles, control means comprising an electromagnet being provided making it possible to bring this mechanism either in a disengaged state, or in its engaged state , the first handle being able to cooperate directly with the bolt, the second handle being able to cooperate with the latter by means of the declutching and clutching mechanism, the declutching and clutching mechanism comprising a gear made up of at least three wheels gears, a first gear wheel cooperating with said first handle, a second gear wheel cooperating with said second handle ée and a third transmission toothed wheel mounted between these first and second toothed wheels, at least one of these toothed wheels being movable, substantially along its axis between a position engaged with the other two toothed wheels and a position disengaged from
  • a device of this kind is known from document DE-A-3310822.
  • These are in particular half-turn bolt locks which can move against a spring when one of the handles is pivoted, 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position, in which the bolt is engaged in a keeper provided in a frame, and an open position, in which the bolt is withdrawn from the strike against this spring.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 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 mobile bolts spaced apart and one of its essential aims is to present a device of the above type of an extremely simple and reliable construction which can especially be mounted on a lock of relatively reduced height and whose movement of the bolt requires a rotation of the handles around a relatively large angle of the order of 90 °.
  • the invention provides a device of the aforementioned type which is characterized in that the electromagnet is mounted substantially coaxially with the third toothed wheel so that when the latter is excited by the passage of a current electric in its winding, this third gear can be subjected to a displacement along its axis, against a spring, from one of the two aforementioned positions to the other position, this spring being arranged so as to allow move and maintain the third gear in its initial position when the electromagnet is not energized.
  • the electromagnet when the electromagnet is energized, it mounted so as to attract the third toothed wheel, which has at least one ferromagnetic part, in its position engaged to the against the aforementioned spring, which is a helical spring mounted coaxially with the electromagnet and the third toothed wheel, this spring making it possible to push the third toothed wheel back into its disengaged position when the electromagnet is not excited.
  • the aforementioned spring which is a helical spring mounted coaxially with the electromagnet and the third toothed wheel, this spring making it possible to push the third toothed wheel back into its disengaged position when the electromagnet is not excited.
  • the invention relates to a door provided with such a security lock.
  • Figure 1 is a front view, in elevation, with partial breaks, of a door part on which is mounted a security lock comprising a device with clutch and release mechanism according to a first particular embodiment of the 'invention.
  • Figure 2 is a side view, partially broken, of this lock with its clutch mechanism and disengagement mechanism, according to this first particular embodiment.
  • Figure 3 is a side view of a second embodiment of the device with clutch and release mechanism according to the invention, in the disengaged position.
  • Figure 4 is a profile view similar to that of Figure 3 in which the device with clutch and release mechanism according to this second embodiment is in the engaged position.
  • a declutching and clutching mechanism is mounted between these handles 2 and 3 and cooperates with control means 7 making it possible to bring this mechanism either into a disengaged state, or into a engaged state.
  • the first handle 2 can cooperate directly with the bolt 1, that is to say by acting directly on the drive mechanism thereof arranged in the housing of the lock itself, while the second handle 3 cooperates with the bolt 1 via the clutch and disengage mechanism 6.
  • the declutching and clutching mechanism 6 comprises a gear made up of three toothed wheels 8, 9 and 10.
  • the first gear 8 cooperates with the first handle 2
  • the second gear 3 cooperates with the second handle 3 and the third transmission gear 10 being mounted between these two gear 8 and 9.
  • the transmission toothed wheel 10 is movable along its axis 5c, between a disengaged position, as shown in solid lines in FIG. 2, and a position engaged with the two cogwheels 8 and 9, as shown in phantom in Figure 2.
  • the control means 7 are arranged so as to allow this third wheel 10 to be moved between its engaged position and its disengaged position.
  • the toothed wheel 8 is wedged on a follower 11 receiving the square rod 12, on which is wedged the handle 2 and which rotates around the axis 5a.
  • the toothed wheel 9 is wedged on a follower 13 receiving a square rod 14 on which the handle 3 is rigidly fixed and which rotates around the axis 5b.
  • the transmission wheel 10 for its part, has a hub 15 which rotates freely around the axis 5c.
  • the aforementioned control means 7 are formed essentially by an electromagnet 16 mounted coaxially with the wheel 10 and allowing, when the latter is excited by the passage of an electric current in its winding, to subject this wheel to a displacement according to its axis, as shown by arrow 17, against a helical spring 18, from its disengaged position to its engaged position.
  • the spring 18 is mounted coaxially with the electromagnet 16 and the toothed wheel 10, so as to allow the latter to be pushed back into its disengaged position when the electromagnet is not excited.
  • At least the hub 15 is made of a ferromagnetic material, more particularly of soft iron.
  • the projecting part 15 of the hub of the toothed wheel 10 which can move in sliding manner in the central part of the winding of the electromagnet 7, has a cylindrical recess 19 in which can lodge the end of the spring 18 oriented towards the toothed wheel 10.
  • the toothed wheel 10 is preferably mounted so as to remain constantly meshed with one of the other two toothed wheels 8 and 9 during its movement between its engaged position and its disengaged position.
  • the toothed wheel 10 is mounted so as to remain constantly meshed with the toothed wheel 8.
  • the plane of symmetry of the toothed wheel 8 perpendicular to the axis 5a of the latter is offset towards the handle 2 relative to the corresponding plane of symmetry of the toothed wheel 9.
  • the teeth (21) of the gear wheels advantageously have a pointed appearance.
  • FIGS. 3 and 4 differs essentially from that shown in FIGS. 1 and 2, by the fact that it comprises two transmission toothed wheels 10 ′ and 10 ⁇ in replacement of the transmission toothed wheel unique 10.
  • These two transmission toothed wheels 10 ′ and 10 ⁇ are coaxial and rotate around a common axis (5c).
  • the toothed wheel 10 ′ remains constantly engaged with the toothed wheel 8, while always remaining free relative to the toothed wheel 9, while the toothed wheel 10 ⁇ remains constantly meshed with the toothed wheel 9 while always remaining free relative to the gear 8.
  • the wheel 10 ′ is movable along its axis 5c between a free position relative to the wheel 10 ⁇ and an immobilized position relative to the latter so as to be able to rotate together with the latter.
  • the wheels 10 ′ and 10 ⁇ have, on their lateral faces opposite, a toothed crown 22 and 23 respectively, the teeth of which mesh, as shown in FIG. FIG. 4, these crowns being in the disengaged position in FIG. 3.
  • the clutch that is to say the axial approximation of the wheels 10 ′ and 10 ⁇ can be done by the excitation of an electromagnet, not shown in Figures 3 and 4, mounted on one of these 10 ′ and 10 ⁇ wheels.
  • a toothed wheel different from the transmission toothed wheel could form one which is movable along its axis to pass from the engaged position to the disengaged position and vice versa.
  • the electromagnet can be excited, for example, using a code via a keyboard, not shown, located on the side of the handle 3.
  • the electromagnet 7 attracts the axially movable toothed wheel, so that the door can be opened by turning the handle 3, provided that the lock is not closed by a key 20. In the latter case, the lock will remain blocked.
