Definitions

  • the invention relates to a door closer according to the features of claim 1.
  • a door closer which is provided with a slide rail linkage.
  • One end of an arm of the slide rail linkage is articulated on the door closer arranged on the door leaf and the other end of the arm is slidably mounted in a rail on the door frame.
  • the end of the arm on the door closer side is connected to an output shaft of a transmission which is coupled to a spring arrangement.
  • the gearbox consists of specially shaped toothed cam disks with a rolling curve profile that results from various radii of the toothed cam disks that are constant in sections.
  • One toothed cam is connected via the output shaft of the door closer to the end of the arm and the further toothed cam is connected to a pinion of the door closer which engages in a toothed rack and which moves the toothed rack against or with the pretension of a spring of the spring arrangement.
  • the changing rolling curve of the two toothed cam disks is intended to counteract the lever arm of the arm which changes with the opening angle of the door leaf, so that the torque of the door leaf required for opening and closing has a predetermined characteristic of the opening angle, in particular a decreasing opening moment is aimed for .
  • EP 0 856 628 A1 discloses a door closer, the drive axis of which is connected to an eccentrically mounted gear. This toothed wheel meshes with its teeth within a tooth region which extends in a straight line at an angle and which is arranged within a piston which interacts with a spring. When the drive axle is rotated, lever arms with different lengths result. This changes the force and torque curve.
  • the invention is based on the object of developing a door closer according to the type specified in such a way that, while avoiding the disadvantages mentioned, a simple, space-saving construction is specified which can easily be designed for desired torque profiles over the opening angle of the door leaf.
  • the invention is based on the knowledge that the force curve - torque curve - which changes over the opening angle of the door - both during opening and closing can be influenced by a device with a transmission ratio which changes via the opening angle and which is arranged by eccentrically arranged and one circular ring gear has gears that are easy to manufacture.
  • the transmission which changes in its transmission ratio over the opening angle of the door, has a first and a second meshing gear, each formed by a circular ring gear, which, while maintaining their center distance which are mounted eccentrically to their center points and of which the first gearwheel is connected to an output shaft and the second gearwheel is connected coaxially to the pivot point to the gearwheel engaging in a toothed rack coupled to the spring arrangement, the axis of rotation of the output shaft running through the pivot point of the first gearwheel, all in such an arrangement that the eccentricity of the gearwheels, which results from the center point of a gearwheel and the new pivot point, is point-symmetrical to its pitch point.
  • the torque curves can now be determined and easily determined by choosing the eccentricity, the pitch circle diameter and the resulting distance between the axes of rotation of the two gear wheels. This results in a variety of gear ratios and thus possibilities for adaptation to the desired torque characteristics over the opening angle, without the need for special designs of toothed cam disks. Rather, commercially available gears can be used, which significantly reduces manufacturing costs. In addition, the gears can in particular have normal teeth.
  • the size of the eccentricity is described by the ratio of the amount of the same to the base circle diameter. In particular, this ratio should not exceed a value of 0.137 for gears according to DIN 867.
  • the door closer is designed as an overhead door closer with an effective lever arm which changes between the articulation point of the moveable door leaf of the associated door and a further articulation point outside the door leaf and which acts on the output shaft.
  • the effective lever arm is preferably formed by a slide rail linkage or a toggle linkage linkage.
  • the door closer can also be designed as a floor door closer, in which the output shaft interacts with the bearing of the door leaf.
  • Figure 1 a schematic view (section) of the transmission of the door closer
  • Figure 2 the two gears of the transmission of Fig. 1 with respect to the position of the center of rotation and.
  • FIG. 1 shows a schematic view of a door closer 10 with gear 12 and spring arrangement 14, which are arranged in a housing 16 of the door closer 10.
  • the spring 14 is coupled to a rack 20 in a known manner via a piston 18 guided in the housing 16.
  • a toothed wheel 22 engages in the toothed rack 20 and is firmly connected to a toothed wheel 24, the axis of rotation 26 of the toothed wheel 22 and the axis of rotation of the toothed wheel 24 being identical.
  • the gear 24 meshes with a further gear 28 which is connected to an output shaft 30 protruding from the housing 16.
  • the output shaft 30 is arranged coaxially to the axis of rotation 32 of the gear 28.
  • the two gear wheels 24 and 28 are provided with normal toothing and are rotatably mounted eccentrically with respect to their central axis 34 and 36 by a predetermined amount e.
  • the axis of rotation 26 of the gear wheel 24 is thus spaced from its central axis 34 and the axis of rotation 32 of the gear wheel 28 from its central axis 36 by the amount e.
  • a toggle lever or a slide rail linkage can act on the output shaft 30 in a known manner.
  • the door closer 10 can also be designed as a floor door closer, the output shaft 30 then interacting with a bearing of a door, not shown here.
  • the meshing gears 24 and 28 are shown in connection with an XY coordinate system, the X axis connecting the two pivot points 38 and 40 formed by the axes of rotation 26 and 32.
  • the center points 42 formed by the central axes 34 and 36 and 44 each have the assigned pivot point 38 or 40 the distance e which determines the eccentricity.
  • the center points 42 and 44 relate to a circular ring gear of the respective gear wheel 24 or 28 with a circular root circle, head circle, rolling circle and others
  • the eccentricity e formed by the center point 42 and the pivot point 38 or by the center point 44 and the pivot point 40 is point-symmetrical to the rolling point 46 of the two meshing gear wheels 24 and 28 in which the two rolling circles 48 and 50 of the gears 24 and 28 touch
  • the gears 24 and 28 have a corresponding design to each other. This enables the distance from the pivot point 38 to the rolling point 46 to increase or decrease as the distance between the pivot point 40 and the rolling point 46 increases as the gears 24 and 28 rotate Reduced or enlarged The distance between the pivot points 38 and 40 of the two gear wheels 24 and 28 to one another remains constant during the rotation of the gear wheels 24 and 28

Abstract

L'invention concerne un ferme-porte automatique (10) comportant un ensemble à ressort (14) à tendre lors de l'ouverture de la porte, qui fournit le couple de fermeture nécessaire pour la fermeture de la porte, ainsi qu'un engrenage (20 à 28) monté entre l'ensemble à ressort (14) et la porte pour influer sur la courbe de la force qui se modifie sur l'angle d'ouverture de la porte. L'engrenage (20 à 28), dont le rapport de transmission se modifie sur l'angle d'ouverture de la porte, présente une première roue dentée (24) et une seconde roue dentée (28) qui s'engrènent et sont formées chacune par une couronne dentée circulaire. Ces roues dentées sont montées, avec maintien de leur écart axial, de façon excentrée par rapport à leur point central (42, 44) respectif, la première roue dentée (28) étant reliée à un arbre de sortie (30) et la seconde roue dentée (24) étant reliée, coaxialement par rapport à son centre de rotation (38), à une roue dentée (22) s'engrénant avec une crémaillère (20) accouplée avec l'ensemble à ressort (14). L'axe de rotation (32) de l'arbre de sortie (30) passe par le centre de rotation (40) de la première roue dentée (28), cela selon un agencement tel que l'excentricité (e) des roues dentées (24, 28) respectivement entre le point central (42, 44) d'une roue dentée (24, 28) et le centre de rotation (38, 40) et les roues dentées (24, 28) est d'une symétrie ponctuelle par rapport à son point primitif (46).
