Definitions

  • the invention relates to a laterally opening roller door with two sheets of flexible material forming the door leaves, one end of which is attached to a vertical closing profile designed as a closing edge and the other ends of which are attached to two vertical winding shafts which are arranged in the region of a vertical frame spar of the door frame and with a guided in a guide of the upper frame profile of the goal frame, the end profile carrying slider or carriage.
  • roller door of this type known from EP-PS 149 138, rapid door movements are to be achieved without guiding means arranged on the floor, which impedes passage, in that the door is driven only by means arranged above the door opening and the trolley carrying the end profile is followed by one is provided at the bottom projecting arm, which initiates the opening and closing forces about halfway into the end profile connected to the webs.
  • the known roller door has a relatively complex construction of the drive means and for coupling the end profile to the trolley, wherein despite the downwardly projecting arm serving for stabilization, considerable acceleration forces act on the end profile when opening and closing, which strain the arm and significantly affect the arm Trolley causing torques.
  • the object of the invention is to provide a roller door of the type specified that can be opened and closed quickly with a simpler and lighter design without the final profile acting on its guidance as a result of acceleration forces in a manner that requires special stabilization measures .
  • this object is achieved in a roller door of the generic type in that the winding shafts are acted upon in the winding rotational direction by a torsion spring or a device generating a winding torque, that at least one extension member is arranged between the vertical frame spar and the end profile, which has the end profile in the closing direction a force exerted on the door leaves and that at least one winding shaft is provided with a brake gear motor driving it.
  • the end profile is acted upon in the closing direction by the extension member, so that the door leaves are under tension in every position of the end profile and are thereby kept taut.
  • This tension results on the one hand from the force exerted by the stretching member on the end profile and on the other hand from the winding torque exerted on the winding shafts or the additional holding force of the brake geared motor or motors.
  • the force exerted in the closing direction on the end profile via the stretching element can be approximately in equilibrium with the winding torques acting on the winding shafts.
  • a brake geared motor or two brake geared motors which act only on one winding shaft or both winding shafts, in the winding or closing direction, this being done by the extension member the closing profile, which is kept under tension, closes the unwound web parts for closing and is drawn in by the wound web parts when opening.
  • the tensioning force of the extension member and the winding torques constantly acting on the winding shafts can also be coordinated with one another in such a way that the forces exerted on the door leaves by the winding torques are greater than the force of the extension member, so that when the motor brake is released, the end profile moves in the opening direction or in is held in its open position. To close the door, it is therefore only necessary that the winding shafts are driven by the or the brake geared motors in the closing direction and the respective closed position of the door is held by the motor brake.
  • the stretching member applies a closing force to the closing profile in the closing direction, which overcomes the winding moments and the frictional forces counteracting the closing.
  • all that is required to close the gate is to drive one or both winding shafts in the unwinding direction or only to release the motor brake.
  • To close the gate on the other hand, it is necessary to drive the winding shafts in the winding direction and to block them in the open position.
  • the closing force of the extension member is expediently chosen so that the gate can also be pushed open by hand, if necessary, for example in the event of a power failure.
  • roller shutter according to the invention is that once the door leaves are held taut by the extension member between the end profile and the winding shafts and that the end profile only has to be provided with a guide, but not also with a drive, because the opening and Closing movements of the gate can be effected solely by driving the winding shafts. Since the opening profile is only acted upon by the stretching member or members, we ken on this no acceleration forces that try to turn it out of its position parallel to itself, so that only the stretching force of the stretching member or members can be overcome.
  • the extension member expediently consists of two toggle levers connected to one another and to the end profile and the vertical frame spar, which are acted upon by springs in the direction of their extended position.
  • Such a toggle-like extension member can be produced in a relatively simple manner with the desired extension force.
  • a swivel member is mounted on the axis connecting the handlebars, to which two springs forming points in all swivel positions in the stretching direction are attached tension springs, the other ends of which in the area of the outer Handlebar ends are attached.
  • the handlebars mounted in the region of the vertical frame spar are additionally mounted such that they can be bent out about a vertical axis. This configuration ensures that the extension member or the toggle link connected to one another are not bent or damaged when the closed gate is forced open.
  • the buckling can take place against a predetermined or adjustable cogging torque.
  • the guide is inclined in the direction of the closed position of the end profile and the winding shafts form right angles with the inclined guide rails. This configuration ensures that the closing profiles only touch the floor in the closed position and are raised immediately when the gates are opened, which rules out undesirable floor friction.
  • the lower edges of the door leaves are cut obliquely in accordance with the oblique course of the lower end of the end profile, so that they do not touch the floor or nearly create it until the closed position.
  • the door leaves are provided in their central regions with wedge-shaped transparent regions widening towards the end profile. These transparent areas allow a view of any obstacles that may be behind the closed gate. Furthermore, the stretching elements can be arranged in the non-transparent areas.
  • the wedge-shaped design of the transparent area causes the connecting seams between the transparent and opaque parts to run obliquely, so that they wind up helically on the winding shafts and do not form beads.
  • two gate leaves arranged in mirror image to one another are provided. Each of these gates can be opened or closed individually. Of course, it is also possible to drive the two gate leaves so that they open and close symmetrically.
  • roller door leaves consists of a door frame 2 fastened in front of a door opening 1, which is formed by side door spars 3, 4, which are connected to one another by an upper frame part 5.
  • lateral spars 3, 4 vertical winding shafts 6, 7 and 8, 9 are rotatably mounted in the usual way, onto which the double sheets 10, 11 and 12, 13 forming the door leaves can be wound.
  • the roller door leaves carry end profiles 14, 15 which are attached to carriages running in the upper door frame 5 arranged guide rails 17.
  • the vertical winding shafts 6, 7 and 8, 9 can be driven in the usual manner by brake gear motors 18, 19 in the opening and / or closing direction.
  • the sheets forming the door leaves 10, 11 and 12, 13 consist of upper and lower impervious visible web parts, which are connected by obliquely running seams 22, 23 and 24.25 to transparent web pieces 26, 27 widening in a wedge shape towards the closing profiles 14, 15.
  • the end profiles 14, 15 are stretched in the direction of the closed position with a closing or the door leaves by stretching members 28, 29 and 30, 31 which are articulated on the one hand on the side door bars 3, 4 and on the other hand on the end profiles 14, 15 Force applied.
  • the stretching members consist of articulated links which are arranged in the manner shown in FIG. 1 between the opaque web parts of the door leaves.
  • the stretching members are described below with reference to FIGS. 5-8.
  • Each extension link consists of two links 35, 36 with a box-shaped or channel-shaped profile. At their mutually facing ends, the links are provided with intermeshing fork-shaped bearing parts 37, 38 and 39, 40 which have an aligned bore.
  • a bearing axis 41 is held in the bores of the inner fork-shaped legs 37, 38, on the ends of which the outer legs 39, 40 of the link 35 are supported via ball bearings 42, 43.
  • a pivot member 46 is mounted on the axis 41 between spacer sleeves 44, 45, which carries a crosspiece above the pivot axis 41, the ends of which are provided with bores 47, 48. These bores 47, 48 are located in the manner shown in FIG.
  • the outer ends of the handlebars are articulated on the one hand with an end profile 14 and on the other hand with one of the frame bars 3, 4.
  • the frame spar ends of the handlebars are articulated to a vertical pin 60 which is rotatably mounted against a predetermined disengagement force in a housing 61 connected to the side spars.
  • the pin 60 locked in the housing 61 has, in the manner shown in FIG. 8, a forked end on which a bearing pin 63 is mounted. On the ends of the bearing pin 63, the lateral legs of an end bearing piece of the link 36 are supported by ball bearings.
  • the outer forked bearing piece 65 is mounted on a pin 66 which is held in the manner shown in FIG. 8 in receptacles 67, 68 of the end profile 15.
