Definitions

  • the present invention relates to control systems for emergency unlocking devices for landing hoist landing doors.
  • an emergency unlocking device In order to allow emergency opening of an elevator landing door, it is known to place an emergency unlocking device on the opening or the frame of this landing door.
  • This emergency unlocking device is generally actuated by means of a key such as a triangle that all the emergency services have.
  • the accommodation receiving this key is located in a location accessible both to the emergency services and to any user and therefore to malicious users.
  • the present invention therefore aims to remedy the aforementioned drawbacks by providing means which make it possible to avoid the malicious use of an emergency unlocking device.
  • the emergency services or authorized persons can actuate the means for controlling the movement of the selection means in order to be able to engage, by means of their operating key, the rotary finger with the member. drive which activates the emergency unlocking device to unlock the door.
  • the rotary finger Even if an unauthorized person has an operating key, the rotary finger being mounted idly when the selection means are in their first position, the emergency unlocking device cannot be actuated.
  • the rotary finger since the rotary finger is mounted idly, it does not offer mechanical resistance and therefore cannot be forced by vandalism. Likewise, since the selection means are inaccessible, they cannot be forced.
  • the drive member and the rotary finger form a dog device.
  • the rotary finger and the control member are movable in rotation about the same axis and are aligned along this axis, the rotary finger also being displaceable in translation along said axis.
  • the selection means comprise a fork movable transversely with respect to the clutch device between the first position in which it is interposed between the rotary finger and the drive member and the second position in which it is released from the device to dog.
  • the selection means further comprises locking means which cooperate, in the first position of the selection means, with the drive member to block the rotation of the drive member.
  • the emergency unlocking device is thus locked in the locked position.
  • the rotary finger comprises a pinion with external teeth and the drive member comprises a crown with internal teeth situated opposite the pinion.
  • the fork delimits a housing in which the pinion of the rotary finger penetrates when the fork is in its first position, the dimension of the fork along said axis being at least equal to that of the pinion.
  • the system further comprises a compression spring which extends along the axis of the dog clutch and which is interposed between the rotary finger and the drive member to separate the pinion and the crown from a space at the less equal to the size of the fork.
  • control means of the fork comprise an electromagnet whose supply of electric current is remotely controlled and causes the displacement of the fork towards its second position.
  • the blocking means comprise a notch formed in the fork and which is intended to cooperate with a lug carried by the drive member.
  • the system further comprises a bearing, a first end of which axially immobilizes the drive member and a second end of which houses the rotary finger sliding and rotating, the bearing further comprising a slot in which the fork is movable transversely to the bearing.
  • the drive member is mounted for rotation with a control rod for a bolt for a swing door of the elevator shaft.
  • the drive member is connected to a control cable for a linkage for an elevator shaft sliding door.
  • FIG. 1 is a perspective view of the whole of the emergency unlocking device and of the control system, this device being installed on the frame of a swinging landing door of the elevator shaft, the operating key being ready for be inserted into the control system.
  • Figures 2 and 3 are respectively perspective and plan views of the unlocking device equipped with the control system according to the present invention, the metal covers having been removed.
  • FIGS. 4 to 7 are respectively exploded perspective views, rear and front perspective, and in longitudinal section of the control system of FIG. 2.
  • Figure 8 is an exploded perspective view of a first variant of the control system.
  • Figures 9 and 10 show a second variant of the control system according to the present invention.
  • the unlocking device 1 shown in Figures 1 to 3 is intended to allow emergency unlocking of a swing landing door for an elevator shaft.
  • this device is mounted in the frame 2 of the swing door (not shown). It is understood of course that, as a variant, this device could be mounted on the opening of the landing door.
  • the emergency unlocking device 1 comprises, in a manner known per se, a lifter 7 which comprises a head 8 and at least one upper branch 9.
  • the head 8 has a shape complementary to that of a key button 10 used by the emergency services or any other person authorized to unlock the door in the event of an emergency.
  • the upper branch 9 of the emergency unlocking device 1 is rotated parallel to the plane of the door, between a locking position of this door in which the bolt 5 is projecting ( as shown in Figures 1 to 3) to enter the keeper of the door, and an unlocking position of this door in which the bolt 5 is recessed inside the frame of the door to release the door from this door.
  • a control system 12 is interposed between the operating key 10 and the emergency unlocking device 1.
  • This control system 12 is more particularly shown in Figures 4 to 7.
  • the system 12 has a drive member 13 which is intended to be connected to the emergency unlocking device 1, and which is movable between a rest position and an active position to drive this device 1 between respectively door locking and unlocking positions.
  • the control system 12 also has a rotary finger 14 which is intended to be driven in rotation by the operating key 10, as well as selection means 15 to selectively allow the engagement of the rotary finger 14 and the member.
  • drive 13 and which are movable between a first position in which the rotary finger 14 is free to rotate relative to the drive member 13 and a second position in which the rotary finger 14 and the drive member are integral in rotation.
  • the system 12 also has control means 16 for moving the selection means 15 between the first and second positions.
  • the drive member 13 is integral in rotation with the head 8 of the lifter 7 and the rotary finger 14 has a front face 11 turned towards the outside of the frame 2 of the door which is of shape complementary to that of the operating key 10.
  • This shape can be triangular, or even polygonal.
  • the drive member 13 and the rotary finger 14 form a dog clutch device of axis Y-Y perpendicular to the axis X-X.
  • the member 13 and the finger 14 are thus movable in rotation about the same axis and are aligned along this axis.
  • the finger 14 In the rest position, that is to say when the emergency unlocking device is not actuated, the finger 14 is mounted idly so that the rotation of the finger 14 does not cause the member 13 to rotate.
  • the selection means 15 are interposed between the finger 14 and the drive member 13 to prohibit the cooperation by gear of the finger 14 and the member 13.
  • the rear face 17 (facing away from the front face 11) of the finger 14 is provided with a pinion with external toothing 18 while the drive member 13 has an internal toothed crown 19 situated opposite the pinion 18 being complementary to this pinion to cooperate selectively.
  • the pinion 18 and the crown 19 are of the same axis and are centered on the axis Y-Y.
  • the finger 14 and the member 13 are biased against each other by a compression spring 20 interposed between the two opposite faces of the finger 14 and the member 13 which respectively carry the pinion 18 and the crown 19.
  • the compression spring 20 is housed in a bore 21 which opens on the rear face 17 of the finger 14 and is in abutment against a lug 22 which protrudes inside the crown 19, from of the member 13.
  • the compression spring can be replaced by a magnet which repels the finger and the drive member one against the other by magnetic repulsion.
  • the finger 14 is thus not only movable in rotation about the axis YY, but also is mounted displaceable in translation along this axis inside a bearing 25.
  • a first end 26 or front end of this bearing is supported against the frame 2 of the door and a second end 27 or rear end of this bearing axially immobilizes the drive member 13 while allowing the rotation of this member around the axis YY.
  • the compression spring 20 makes it possible to separate the finger 14 and the drive member 13 by freeing up a space in which the selection means 15 penetrate, when the unlocking system 1 must not be actuated, to be interposed between the finger 14 and organ 13.
  • the selection means 15 comprise a fork 30 movable in translation along the axis XX, parallel to the direction of the double arrow F (FIG. 7), and which defines a housing 31 in which the pinion 18 penetrates when the fork 30 is interposed between the finger 14 and the drive member 13.
  • the fork 30 extends transversely to the bearing 25, being external to the latter, and penetrates inside this bearing through a opening 32 to reach the pinion 18.
  • the selection means 15 further comprises means for locking in rotation 37 of the drive member 13 which cooperate with this member 37 when the selection means are in the first position.
  • the locking means comprise a notch 37 located in the bottom of the fork 31 and the drive member 13 has a lug 38 which projects along the axis YY from the crown 19. This lug penetrates into the notch 37 when the fork 30 is in the first position in which the finger 14 is mounted mad. The emergency unlocking device is then locked in the locked position.
  • the locking means 37 can also take the form of two flats carried by the member 13 intended to cooperate with complementary shapes of the fork 30.
  • control means 16 which may for example be an electromagnet.
  • the fork 30 is movable between a first position in which it is interposed between the finger 14 and the member 13 as shown in FIGS. 5 to 7, and a second position in which the electromagnet has driven the fork 30 towards the bottom to release it from finger 14 and thus allow finger 14 to be pushed back towards the member 13, against the force of the compression spring 20.
  • the fork 30 is biased by another compression spring 35 towards its first position.
  • the supply of electric current to the electromagnet 16 causes the fork 30 to move from its first position to its second position, against the force of the spring 35.
  • the supply of electric current to the electromagnet 16 is controlled remotely from the system 1, at a location separate from the operating key 10. This location is preferably not apparent to an untrained user. It is for example located in the room where the drive motor of the elevator car is located.
  • the operating key 10 can on the one hand drive the finger 14 in translation along the axis YY to come cooperate with the member 13, but also in rotation to drive in rotation of the member 13 between its locking position of the landing door and its unlocking position of this door.
  • control system 12 comprises the same parts constitutive, the drive member is however no longer integral in rotation with the head 8 of the lifter 7, a cable 40 housed in an envelope 41 is slidably driven by the rotation of the member 13.
  • This cable 40 is intended to be connected to a linkage (not shown) for a sliding elevator shaft door.
  • the operation of the control system 12 is identical to that described above.
