Definitions

  • the present invention relates to an actuating device with a reversible nut and screw for operating a movable element in translation, such as a sliding door leaf, the displacement of which can be obtained either automatically by means of a motor connected to the screw, either manually, especially in an emergency, thanks to the reversible nature of the screw-nut connection.
  • the invention relates more particularly to the locking of such a movable element in translation and applies in particular to the locking in the closed position of a sliding door or of a pair of such conjugate doors, such as doors of transport vehicles. in common, with automatic opening and / or closing, railway vehicles in particular.
  • FR-2 417 620 discloses a device for locking a sliding door, the leaf of which is connected in translation to a nut mounted on a reversible driving screw, rotated by a motor to open and / or closing the door, this nut being guided in a slide which prevents its rotation.
  • means are provided for interrupting, at the end of the travel, the translational guidance of the nut and allowing its angular rotation with the screw so that a locking finger linked to the nut engages in a formed keeper. on one side of the slide, as a result of which the finger engaged in the strike obstructs any translational movement of the nut and therefore of the leaf. Such locking is necessary because of the reversible nature of the screw-nut connection.
  • This device therefore provides the automatic locking and unlocking functions.
  • Means other than the motor are also provided which make it possible, from the locked position, to pivot the nut to unlock it, after which the leaf can be manually pushed into the open position by rotation of the opinion. This allows emergency opening, for example in the event of an engine failure. It is to allow emergency opening that the screw-nut connection is chosen of the reversible type.
  • provisional unlocking which consists in allowing users to unlock, while maintaining the doors closed by motor supply in the closing direction. This allows, in a semi-emergency situation, to invite passengers to unlock before the vehicle has reached the planned evacuation location, or when a breakdown is feared without knowing whether this breakdown will occur before l arrived at the quay. It is therefore a question of releasing the passengers as quickly as possible, but only when the time is right.
  • the mechanic can draw the attention of passengers, for example by loudspeaker, to such and such a precaution to be taken to minimize the risk of accident.
  • the object of the present invention is an actuation device with a reversible nut and screw inexpensive to produce, which does not have the above drawback, and which allows, in addition to the immediate unlocking of the door, its provisional unlocking.
  • the subject of the present invention is an actuating device with a reversible nut and screw for operating an element such as a sliding door leaf, the device comprising a screw connected to a motor, a carriage movable along the screw and connected to the less indirectly to said element, the carriage comprising a nut mounted on the screw and a latch for automatically locking the carriage when the nut reaches one end of its travel and for automatically unlocking the carriage when the screw is moved in the direction tending to move the nut away from said end of its travel, the device comprising means limiting the rotation of the nut about the axis of the screw, characterized in that the lock is movable relative to the nut and urged towards a locked position by a spring, and in that the device comprises a force transmission member connected to the nut with a clearance, and means sensitive to the relative position of the nut and of the force transmission member to allow the spring to bring the lock into the locked position when the screw turns in the direction urging the nut towards said end of its travel and to bring back positively the latch
  • the present invention also relates to a sliding leaf door, in particular for a railway vehicle, comprising a leaf associated with a device as described above and means for returning the lock to the inactive position against the action of the spring and independently of the means sensitive to the relative position of the nut and of the force transmission member .
  • the lock When the carriage reaches its end of travel, the lock automatically switches to the locking position under the action of the spring because the screw turns in the direction urging the nut towards said end. It is therefore the spring, and not the force of the screw, which caused the locking, and therefore, to operate a "manual" unlocking, it is enough to overcome the force of the spring even if the screw is stressed in the direction of the closure. For automatic unlocking, it suffices to rotate the screw in the opposite direction, the means sensitive to the relative position of the screw and of the force transmission member then bring the lock positively back to the inactive position.
  • a device is therefore produced in which, on the one hand, the driving screw can automatically drive the latch in the locking or unlocking position, and with which, on the other hand, that the engine is stopped, it is turned in the direction of closing, the door can be unlocked manually by only overcoming the force of the return spring of the lock, this latter force being able to be predetermined to allow easy manual operation.
  • the lock is partially dissociated from the kinematic chain and the additional function of the provisional unlocking can be fulfilled with simple and economical means.
  • a device according to the invention has been shown in Figures 1, 2, 3 and 4 in the case of a door having a single leaf 1, which can move between an extreme closed position indicated in solid lines and an extreme position opening shown in dotted lines.
  • the leaf 1 is suspended from a fixed rail 5 by two suspension plates 7, fixed on the upper edge of the leaf 1 and respectively articulated on two movable supports 8, moving along the rail 5 by means of wheels 8a.
  • the displacement of the leaf 1 is produced by an electric motor 2 driving in rotation a screw 3 of axis HH ′ parallel to the rail 5 and on which is mounted a carriage 11.
  • the latter is generally prevented from turning around the axis HH ′ and moves in one direction or the other along the screw 3 according to the direction of rotation of the latter.
  • the screw 3 is rotatably mounted on two fixed bearings 4 made integral with the rail 5, itself fixed to the frame of the door not shown.
  • the carriage 11 drives the leaf 1 by means of a coupling 13 fixed to the leaf 1 and linked in translation to the carriage 11.
  • the carriage 11 comprises a nut 14 itself composed of a tubular member 17 surrounding a ball cage 18 to which it is fixed by screws 20.
  • the balls 18a of the cage 18 roll in the helical grooves 19 of the screw 3.
  • the tubular member 17 carries a ring 41 immobilized axially on the nut 14 between a shoulder 42 and an elastic ring 43.
  • the ring 41 has an outer bearing spherical 44 on which a spherical bore complementary to a collar 12 constitutes the upper end of the coupling 13.
  • two adjacent rings are mounted along a contact plane PP ′ transverse to the axis HH ′, a guide or anti-rotation ring 15 and a locking-unlocking ring 16.
  • the rings 15 and 16 are mounted free to pivot on the nut 14 around the axis HH ′ but are prevented from moving axially thereon by an elastic ring 48 and a spacer 49 supported on the ring 41.
  • the amplitude of the pivoting of the rings 15 and 16 relative to the tubular member 17 is limited by a boss 31 welded to the tubular member 17.
  • the boss 31 is crossed by the contact plane PP ′ of the rings 15 , 16. It cooperates with two respective notches 33, 34, of the same dimensions, formed on the edge of each ring adjacent to the plane PP ′ (see FIG. 3).
  • the extreme angular positions of the locking ring 16 correspond to the positions of the notch 34 in which one or the other of the circumferential ends 34a, 34b, forming a stop, is supported circumferentially on the boss 31 It is the same for the extreme angular positions of the guide ring 15, which correspond to the positions of the notch 33 in which one or the other of the circumferential ends 33a, 33b of this notch is supported on the boss 31. In FIG. 3, these circumferential ends are not visible because the notch 33 is partially concealed.
  • the angular travel of each ring 15 or 16 has the same maximum value A of approximately one eighth of a turn relative to the nut 14.
  • the rings 15, 16 respectively carry a guide finger 21 and a locking finger 22 each carrying a roller 28 held by a screw 26 screwed into a thread formed in the finger 21 or 22.
  • the screws 26 are blocked by pins 25 force-fitted into the fingers, each pin comprising a curved part 27, at its end opposite the penetration end.
  • the ends 29a and 29b of the spring are hooked to the fingers 21 and 22 and retained radially by the parts curved 27, which thus avoid unwanted deformations of the spring.
  • the guide finger 21 constitutes a slide permanently engaged, by its roller 28, in a slide 23 ( Figures 1 and 3) fixed to the door frame and parallel to the screw 3.
  • the guide finger 21 thus transmits between the boss 31 linked to the nut 14 and the slide 23 the reaction force necessary to prevent the nut from turning with the screw except on the angular travel A allowed by the notch 33.
  • the slide 23 comprises two opposite and parallel bearing walls 23a and 23b, spaced a distance slightly greater than the diameter of the rollers 28.
  • the slide 23 therefore permanently prevents the guide ring 15 from rotating around the axis HH ′ .
  • the roller 28 of the locking finger 22 is also located in the slide 23.
  • the spring 29 rotates the ring 16 relative to the ring 15 in the direction pressing the locking finger 22 against the wall 23b, against which the guide finger 21 rests when the screw turns in the closing direction of the leaf.
  • the slide is connected, at one of its ends, and on the side of the wall 23b, to a strike 24.
  • the keeper 24 has two parallel walls 24a and 24b, transverse to the axis HH ′ and the mutual distance of which is slightly greater than the diameter of the roller 28.
  • the wall 24a is linked to the wall 23a and therefore closes the slide 23.
  • the wall 24b is linked to the wall 23b.
  • the walls 24a and 24b are connected by a wall 24c which closes the keeper 24 at its circumferential end distant from the slide 23.
  • manual unlocking means comprising a plate 37 which can pivot about a fixed axis 40 oriented parallel to the axis HH ′ so as to be able to sweep the keeper 24.
  • the plate 37 is controlled by a rod 39 provided a movable articulation 41.
  • the plate 37 When the finger 22 is in the locking position under the action of the spring 29, if there is manual action on the rod 39 according to F (FIG. 4), the plate 37, initially interposed between the roller 28 of the finger 22 and the wall 24c, pivots about the axis 40 and drives in its movement the finger 22 until it is brought into alignment with the slide 23, which causes the unlocking of the door.
  • Manual unlocking is obtained by operating the rod 39 in the direction F (see FIGS. 3 and 4), which makes it possible to exert an action tending to pivot the finger 22 against the action of the spring 29 to replace the finger 22 in alignment with the finger 21 and with the slide 23.
  • the possibility of manually opening the door should be checked. This is possible by supplying motor 2 in the direction of the closure. In this case, the passengers 5 can unlock the leaf manually by not encountering any resistance other than that of the spring 29, since the rotation of the ring 16 between the locking and unlocking positions is made relative to the nut 14 therefore without requiring rotation of the screw. On the other hand, the user who has unlocked manually cannot open the leaf as long as the motor is supplied in the closing direction. Thus, the desired function, namely to allow prior manual unlocking while leaving the machinist the control of the effective opening is perfectly ensured.
  • automatic provisional unlocking can be achieved by a simple means such as the closing of an electrical circuit caused by the operation of the door unlocking handle, the unlocking becoming effective only if the machinist cuts this electrical circuit by means of a switch.
  • the door can be automatically unlocked by starting the motor 2 driving the screw 3, by rotating the screw in the opening direction indicated by the circular arrow of Figure 8.
  • the force transmission means are rotatable relative to the nut.
  • it could also be translation means, for example a play in translation between the nut and the leaf drive part.
