Definitions

  • the present invention relates to electrically controlled closing devices of the type of roller shutters and the like.
  • the means associated with the two freewheel members comprise on the one hand a cylindrical part in the form of a support integral with the drum and provided with lateral toothing, on the other hand a disc made angularly integral with the member of the freewheel which is permanently linked to the output shaft of the gear motor.
  • This disc itself has a toothing conjugated to the aforementioned toothing, the two toothing being kept applied against one another by elastic means so that said disc moves axially against the elastic means for actuating the electrical contactor when its toothing is pushed axially by the opposite toothing under the effect of the angular immobilization of the drum which occurs when the apron strikes an obstacle.
  • Fig. 1 is a schematic axial section of a roller shutter device equipped with a safety mechanism established in accordance with the invention.
  • Fig. 2 is a cross section on a larger scale along the plane indicated in II-II in FIG. 1.
  • Fig. 3 shows in perspective the main elements of the safety mechanism.
  • Fig. 4 is an axial section of this mechanism assumed to be in the operating position.
  • Fig. 5 is a very simplified diagram of the electrical installation of the device according to FIG. 1.
  • the roller shutter device shown in FIG. 1 comprises a movable deck 1, the upper edge of which is made integral with a rotating operating drum 2, which is rotatably supported, at its ends, by two brackets 3 fixed in the doorway 4 closed by the device in question. Inside this drum 2 is housed an electrically controlled geared motor 5, the carcass or stator of which is carried by one of the brackets 3, while its output shaft at low speed is angularly linked to said drum 2 by a free wheel 6.
  • this freewheel 6 comprises two concentric members 7 and 8.
  • this ring or member 8 are formed four cavities each of which contains an oblique finger 11 associated with a spring 12 which, when the shaft 10 drives the member 8 in the direction indicated by the arrow F, tends to engage said finger in one of a series of imprints 7 a made in the opening of the external member 7.
  • a drive sleeve 13 which is made integral, by means of screws such as 14, with the internal member or ring 8 of the freewheel 6.
  • a spacer 15 with a square section which extends axially in the drum 2 beyond said free wheel 6.
  • the end piece 16 a (fig. 3 and 4) d a shaft 16 which passes axially through a cylindrical support 17 mounted inside the corresponding end of the drum 2 with which it is made integral by means of radial screws 18.
  • the support 17 is integral with a cylindrical axial extension 17 a which is engaged in a bearing 19 carried by the bracket 3, as shown in fig. 4.
  • the axial retention of the shaft 16 is effected with the aid of an annular flange 16b adapted to bear against the inner face of the support 17.
  • the free transverse face of the support 17 which is located beyond the bearing 18 is machined to have a toothing 17 b which is intended to cooperate with a conjugate toothing 20 a formed on a tubular boss 20 b forming a hub for a disc 20.
  • the latter is carried by the shaft 16 to which it is angularly linked by a transverse pin 21 inserted into an axial lumen 20 c formed in an extension 20 d of the disc 20.
  • this geared motor 5 in the two directions of rotation corresponding to the raising and lowering of the deck 1 is ensured by a switch 26 which, for the convenience of the explanations, has been assumed to be actuated using two opposite windings 26 a and 26 b , the first operator for the ascent of said deck, the second for the descent.
  • the operation of the switch 26 by the user is carried out using a selector 27 which can be either of the manual type or of the remote control type.
  • This movable selector 27 is coupled to the movable member of a relay 28 which, when it is excited while the deck 1 descends, brings said selector 27 back to the position for which the winding 26 a is supplied.
  • the above-mentioned contactor 24 is connected to the supply of this relay 28.
  • the relay 28 is energized and consequently ensures the return of the selector 27 to the position corresponding to the supply of the coil 26 a , so that immediately after being immobilized during its downward movement, the apron 1 rises while releasing the obstacle. The security thus obtained is total.

  1. Sicherheitsvorrichtung für elektrisch gesteuerte Schließeinrichtungen, die mit einem zwischen der Abtriebswelle (10) eines elektrischen Antriebsmotors mit Getriebe (5) und der Betätigungstrommel (2) eines Rolladens (1) angeordneten Freilauf (6) versehen sind, wobei der Freilauf zwei konzentrische Teile (7, 8) umfaßt, denen Mittel zugeordnet sind, welche derart angeordnet sind, daß die Relativbewegung, die zwischen den vorgenannten Teilen auftritt, wenn die freie Kante des Rolladens (1) beim Ausfahren gegen ein Hindernis im Verlauf ihrer Abwärtsbewegung die Trommel (2) bezüglich ihres Drehwinkels anhält, durch die Betätigung eines zweckdienlicherweise an der elektrischen Versorgungsschaltung des Getriebemotors (5) angeschlossenen Schalters (24) die automatische Umkehrung der Drehrichtung der Trommel (2) sowie das unmittelbare Wiederanheben des Rolladens (1) bewirkt,
    dadurch gekennzeichnet, daß
    die den Teilen (7, 8) des Freilaufs (6) zugeordneten Mittel einerseits eine fest mit der Trommel (2) verbundene und mit einer seitlichen Verzahnung (17b) versehene Stützeinrichtung (17) und andererseits eine drehfest mit dem Teil (8) des Freilaufs (6) verbundene, mit der Abtriebswelle (10) des Getriebemotors (5) ständig fest verbundene Scheibe (20) mit einer seitlichen Gegenverzahnung (20a) haben, daß elastische Mittel (22) die Verzahnung (17b) ständig beaufschlagen, wobei sich die Scheibe axial gegen die elastischen Mittel (22) verschiebt, um den elektrischen Schalter (24) zu betätigen, wenn ihre verzahnung (20b) infolge des Anhaltens der Trommel (2) bezüglich ihres Drehwinkels, das beim Aufprall der freien Kante des Rolladens (1) auf ein Hindernis auftritt, von der gegenüberliegenden Verzahnung (17b) axial zurückgedrängt wird.
  2. Vorrichtung nach Anspruch 1,
    dadurch gekennzeichnet, daß
    die Winkelbeziehung zwischen der Scheibe (20) und dem Teil (8) des Freilaufs mittels eines Zwischenstücks (15) hergestellt wird, welches sich axial im Inneren der Trommel (2) entgegengesetzt zum Freilauf (6) erstreckt, und dessen eines Ende in einer fest mit dem Teil (8) verbundenen Mitnahmehülse (13) aufgenommen ist, während das entgegengesetzte Ende eine Welle (16) aufnimmt, die die fest mit der Trommel (2) verbundene Stützeinrichtung (17) frei durchdringt, um die Scheibe (20) zu tragen, welche drehfest mit der Welle verbunden ist und dem Einfluß der elastischen Mittel (22) folgend oder gegen diesen axial auf der Welle verschiebbar ist, um die Betätigung des Schalters (24) sicherzustellen.
