Definitions

  • the invention relates to a roller door drive device with a distance adjustment of the axis of rotation of the winding door accommodating the door leaf (the armor, the rolling grille or the like) from the fall of the door opening to be closed or the like as a function of the closed or opened position of the door leaf for its inlet-outlet outlet Alignment to the guides for the door leaf provided to the side of the door opening, the distance adjustment being at least approximately synchronized with the closing and opening movement of the door leaf, and the distance adjustment of the axis of rotation of the winding shaft by guiding along an at least approximately linear displacement path of the bearing blocks of the winding shaft relative to the associated side consoles to be arranged in the lintel area.
  • Roller shutters of the type in question have been known for a long time; they are used in particular for closing door openings or the like in which there is sufficient space in the interior area behind the lintel which delimits the door opening upwards, for arranging a winding shaft on which the door leaf is located in the form of rods articulated in the winding direction, also lattice members or the like is wound up in the course of the opening movement and unwound in the course of the closing movement.
  • the elements that are connected in this way in an articulated manner to form the door leaf have a thickness which, depending on the design, is not to be undercut - in particular in the case of a temperature-insulating and / or burglar-resistant type, which is why the winding which forms around the winding shaft in the course of the opening process causes correspondingly large changes in diameter .
  • the door leaf - often called a tank here - is on the train the closing movement has to be initiated in lateral guides, the door leaf elements can only be inserted into the guides with as little friction and gently as possible if they are fed in the same direction in the insertion area of the vertical guides.
  • the invention has for its object to provide a displacement guide between the bearing blocks of the winding shaft and the associated brackets for the distance adjustment movement of the type described, which is reliable, low-noise and low-maintenance and can be operated with low friction losses.
  • this object is achieved in that the essentially straight-line guidance of the bearings relative to the brackets is formed by at least one four-link chain for each mounting and associated bracket.
  • Four-link chains are generally known as transmission means and can be designed in a variety of ways.
  • the peculiarity of the use of such four-link chains for the adjustment movement of the winding shaft axis in relation to the lintel of the door opening to be closed lies in the fact that, due to the pivoting movement of the adjusting device, which takes place primarily, only in a structurally simple manner low friction losses are achieved, in contrast to the previous solutions, which are also much more susceptible to contamination.
  • the four-link chains formed by lever arrangements are designed in such a way that each lever arrangement has a one-armed articulated lever and an approximately twice as long two-armed lever, in the central region of which one end of the one-armed articulated lever is articulated, the other end of which is connected to the associated bracket or the associated storage via a swivel bearing is connected so that the two-armed lever is either slidably guided at its end facing away from the swivel bearing of the one-armed shaft or approximately pivotably connected to the console by means of a further one-armed lever and is pivotally connected to the console and in the same way as the swivel bearing of the one-armed arm Lever is articulated to the console or the bearing and that the other, the pivot bearing of the one-armed lever in the direction of adjustment of the winding shaft axis adjacent end of the two-armed lever on the other of the i
  • the Lever arrangement or the lever arrangements are provided at least on one side of the door opening between the console or between the console and this or associated aprons, which are formed on the trestle of the associated storage and are approximately in a vertical plane parallel to the correspondingly aligned sides extend the console and which in particular serves to hold an electric gear motor driving the winding shaft via a traction mechanism gear.
  • an angle of less than 90 °, in particular about 25 °, is preferably included in the end positions of the adjustment movement.
  • the one-armed lever is subjected to tensile load and the arm section of the two-armed lever, which extends between the articulation of the one-armed lever and the two-armed lever and its articulation on the other part in each case - console / apron.
  • the one-armed lever can be subjected to pressure and the arm section of the two-armed lever extending between the articulation of the one-armed lever on the two-armed lever and its articulation on the other part - console / apron.
  • At least one of the lever arrangements which follow one another in the adjustment direction is assigned a further lever arrangement of the same design which is spaced apart in the axial direction of the articulations and which are operatively connected to one another in rotation about the same respective axes.
  • the axial connection between the pivot points of the one-armed lever and the two-armed lever of the same-axis parallel lever arrangements can advantageously be made via recesses running in a circular arc around the other ends of the one-armed lever.
  • the direction of the distance adjustment from the horizontal to the lintel of the door opening to be closed is designed to fall off, namely from small drop angles up to 45 °.
  • the four-link chains provided according to the invention enable a strictly linear movement path of the winding shaft axis in the course of the Distance adjustment, depending on the lever dimensions and / or guidance, however, a slightly curved course of the movement path can also be achieved, this course preferably being arched towards the bottom, so that the distance to be applied to the winding shaft in the course of winding up the door leaf for the distance adjustment Force equalized.
  • a movement path directed towards the ground can be given, so that the force required for the distance adjustment is correspondingly smaller when the door leaf is still predominantly unwound.
  • a locking device is provided for assembly purposes, in particular one for the assembly of the bearings or aprons in the vicinity of the lintel and / or one substantially removed from the lintel for the assembly of the fully wound winding shaft.
  • at least some of the anchoring points of the four-bar chains can be designed to be damped by means of a rubber-metal element or the like.
  • the distance adjustment in question between the winding shaft axis and the lintel for the purpose of unimpeded insertion of the roller shutter door into the sliding guides attached to the side of the door opening is preferably effected by an adjusting device in the manner of a differential block and tackle, such that the drive of the adjustment movement is derived from the winding shaft drive. so that the synchronization between the winding and unwinding movement of the roller shutter curtain, grille or curtain on the one hand and the adjustment movement of the winding shaft axis with respect to the fall of the door opening to be closed is inevitable.
  • the use of a differential block and tackle in this context is characterized by the fact that the classic "load block" is the driving element here.
  • this adjusting device comprises two fixedly rotatably mounted, torsionally interconnected winding bodies, one of which has a larger winding and unwinding diameter than the other, and that a continuous traction means that can be wound up and unwound both on the one and on the other winding body, is driven by a gearwheel arranged on the driven winding shaft axis in a rotationally fixed manner as a function of the gearshaft drive movement.
  • the winding bodies are preferably circular cylindrical Shell surfaces equipped, each of which has a helically propagating receiving groove for the traction means in the axial direction.
  • such an adjusting device can be designed to be frictionally engaged, but slip phenomena lead to increasing errors, which is why, in a particularly preferred embodiment, the engagement between the traction means, the drive wheel and the winding body is designed to be form-fitting in the direction of tension.
  • the traction means can be designed as a flexible strand with bulges that are successively equally spaced apart in the manner of a toothing, to which the drive wheel and the winding bodies are adapted.
  • the distance between the winding bodies and the drive wheel on the winding shaft axis can be relatively small in the case of the wound door leaf. Due to the traction mechanism between the drive wheel and the two winding bodies, either lateral displacements or rotations by 90 ° when viewed in the direction of the strand are required - see exemplary embodiment - which, in a preferred embodiment, lead to the traction mechanism being designed as a very narrow belt or as a rope, to which preferred Bulges made of plastic are injection molded, in particular in such a way that the plastic of the tooth-shaped bulges positively engages through the strand or the rope.

  • two four-link chain devices 12 and 13 are provided per console or axial side region of the door leaf in the direction of adjustment of the axis 6 with respect to the lintel 2, which — according to the exemplary embodiment shown — are arranged on both sides of a console wall 10 and are connected to each other in the same way.
  • the four-link chain comprises a one-armed lever 14 or 14 'and a two-armed lever 15 or 15', the one-armed lever being articulated at 17 on the console and articulated at 16 approximately in the central region of the two-armed lever 15 Connection is established.

  • the two bobbins are rotatably rotatably mounted on one another on a fixedly mounted axle, so that when the bobbin 34 of larger diameter is wound up while simultaneously winding off the bobbin of smaller diameter, there is a reduction in the distance between the stationary mounting of the bobbin and the winding shaft, so in this way that the distance of the winding shaft axis 6 from the lintel 2 is increased, as is required by increasing bale formation when the gate is opened.
  • the gear train 33 is unwound from the larger diameter winding body 34 and wound onto the smaller diameter winding body by a corresponding drive direction of the gear wheel.
  • the gear train 33 is subjected to an entanglement by 90 °. If the winding bodies 34 and 35 were rotated by 90 ° with respect to their axis of rotation 36, the run-up of the gear train 33 would take place without entanglement, but there would be a different course of the train from the radial plane of the gear wheel 32. For this reason, there is a need for a gear train 33 which is as insensitive as possible to possible deviations from the up and down direction and / or entanglements. Thus, only a relatively narrow belt or, better still, a rope can be considered, in which the tooth-shaped bulges required for the non-slip transmission of motion are designed to encompass all around.
  • FIGS. 9 to 11 show the guidance relationships for the gear train using the exemplary embodiment shown in FIG. 8, the winding bodies 34 and 35 having different diameters are formed with a cylindrical outer surface, on each of which helically reproducing receiving grooves for the gear train 33 are provided in the axial direction.

Abstract

L'invention concerne un dispositif d'entraînement pour porte roulante, dans lequel se produit un décalage entre l'axe de rotation (6) du cylindre d'enroulement (5) recevant le panneau de la porte et le linteau (2) de l'ouverture (1) à fermer. Ce décalage se produit en fonction de la position de fermeture ou d'ouverture atteinte par le panneau en vue de son alignement, à l'entrée et à la sortie, avec les éléments de guidage (3) dudit panneau, disposés de chaque côté de ladite ouverture. Il se produit de manière au moins sensiblement synchronisée avec le mouvement de fermeture et d'ouverture du panneau de la porte. Le décalage de l'axe de rotation 86) du cylindre d'enroulement (5) se prduit par le fait que les paliers (7) de ce dernier sont guidés de façon à effectuer un mouvement de décalage, au moins sensiblement rectiligne, par rapport aux consoles (10) disposées de chaque côté de l'ouverture (1) dans la zone du linteau. Ledit guidage se produit d'une manière sûre, peu bruyante et ne nécessitant que peu d'entretien, ainsi qu'avec des pertes par frottement minimes, entre les supports de paliers du cylindre et les consoles associées. De cette manière, le guidage sensiblement linéaire des paliers (7) par rapport aux consoles (10) est constitué, pour chaque palier (7) et chaque console associée (10), d'au moins une chaîne cinématique à quatre joints articulés (1 à 4; leviers 14, 15).
