Definitions

  • the invention relates to a door operator for opening and / or closing a door leaf.
  • Door actuators can be designed as door closers, servo door closers or door drives, for example.
  • the door operator can be arranged above the door leaf or as a floor spring. It is also possible to arrange a door operator in a hinge of the door.
  • the type of door operator considered here has a cam disk.
  • the cam disk is located on the output shaft.
  • the output shaft is connected to the door leaf directly or via a linkage.
  • Moving elements are arranged in the door operator on both sides of the cam disk, for example designed as damping pistons and opening pistons.
  • the movement elements can be moved linearly in the door operator.
  • the rotary movement of the output shaft is converted to the linear movement of the movement elements and vice versa via the cam disk
  • the object is thus achieved by a door operator for opening and / or closing a door leaf.
  • the door operator comprises a housing and an output shaft rotatably mounted in the housing with a cam disk.
  • the cam disk can be an integral part of the output shaft or, for example, it can be attached to the shaft.
  • the output shaft is designed to transmit torque to the door leaf.
  • the output shaft can be connected directly to the door leaf or to a linkage, for example via a polygon. The linkage then leads in turn to the door leaf.
  • first movement element and a second movement element are guided in a linearly movable manner in the housing.
  • the first movement element has a first contact surface.
  • the second movement element has a second contact surface.
  • the two contact surfaces are preferably each formed by a roller that is rotatably arranged in the moving element.
  • the two contact surfaces are arranged on the cam disk for rolling.
  • the cam disk is located between the two movement elements and thus between the two contact surfaces.
  • the two contact surfaces roll on two opposite sides of the cam disk on the cam disk.
  • the door operator can be designed, for example, as a door closer, servo door closer or door drive.
  • the two movement elements in the housing of the door operator can basically be moved passively, for example by applying spring force, or actively, for example by hydraulic pressure.
  • the movement of the movement elements is converted into a rotary movement of the output shaft via the cam disk.
  • the force applied to the door leaf is transferred into a rotary movement of the output shaft.
  • This rotational movement of the output shaft in turn leads over the Cam disc to a linear movement of the two movement elements.
  • the first movement element is designed in particular as an opening piston.
  • This opening piston is preferably spring-loaded with a first spring (closing spring) in such a way that the first spring presses the first movement element in the direction of the cam disk.
  • the spring is tensioned.
  • the energy stored in the spring can be used to move the first movement element in the direction of the cam disk and thus to close the door.
  • the first spring is also provided. The spring is not only tensioned by manual actuation of the door, but an opening of the door leaf is recognized and actuators in the door operator are activated, which in turn apply the full or partial force to tension the spring.
  • the first spring can then be relaxed in order to move the first movement element in the direction of the cam disk.
  • the second movement element is designed in particular as a damping piston.
  • a damping piston In particular, there is a hydraulic chamber in the housing. By moving the damping piston, fluid is displaced from the hydraulic chamber through a throttle, which results in damping of the movement of the damping piston and thus also damping of the rotary movement of the output shaft.
  • the two movement elements can basically be linearly moved independently of one another, so that the distance between the two movement elements can basically change.
  • both contact surfaces are always in contact with the cam disk.
  • This has the advantage that the geometry of the cam disk can be selected relatively freely and the cam disk accordingly does not have to have the same diameter between the contact points and the contact surfaces for every rotational angle position.
  • the cam disk can have a pointed area. This pointed area is usually present at a rotation angle position of 0 ° (closed door leaf) on the second contact surface, for example the damping piston.
  • the radius of the cam disk at this pointed area is relatively small, so that there is a relatively high surface load on the cam disk.
  • the door operator comprises a spacer arrangement arranged in the housing.
  • the spacer arrangement is designed in such a way that it limits the minimum distance between the movement elements in at least one restriction angle of rotation range of the output shaft. With the restriction of the minimum distance, it is described here that with this restriction the two movement elements cannot move any further towards one another. An increase in the distance between the two moving elements, that is to say moving the two moving elements away from one another, is not restricted by the spacing arrangement.
  • at least one free rotation angle range of the output shaft is defined. In this at least one free angle of rotation range, the linear mobility of the two movement elements is not restricted by the spacer arrangement.
  • the two movement elements can be moved so far towards one another, without being restricted by the spacing arrangement, that both contact surfaces on the cam disk issue.
  • the spacer arrangement is designed in such a way that only one of the two contact surfaces rests against the cam disk and the other contact surface is spaced apart from the cam disk. This spacing of one contact surface from the cam disk avoids the surface pressure described above.
  • the spacer arrangement is designed in particular in such a way that both contact surfaces rest on the cam disk in each free rotation angle range.
  • the two movement elements for example designed as opening pistons and damping pistons, can be moved in different ways in the housing.
  • both movement elements can each be moved in the direction of the cam disk with a spring.
  • the design and arrangement of the springs is chosen so that the first contact surface (of the first movement element) rests against the cam disk and the second contact surface (of the second movement element) is spaced apart from the cam disk in the rotational angle restriction range.
  • the spring force acting on the first movement element is greater than the spring force acting on the second movement element.
  • the cam disk is heart-shaped.
  • This heart shape is characterized by a pointed area of the cam disk and a recess area of the cam disk opposite the pointed area.
  • the pointed area of the cam disk is in particular at a rotational angle position of 0 °. With the angle of rotation position of 0 °, the closed state of the door leaf is described in particular.
  • the indentation area of the heart-shaped cam disk does not have to lie exactly opposite the pointed area, but is located approximately in the area of 180 °, starting from a pointed area at 0 °. In particular, the center of the depression area lies between 120 and 240 °.
  • the angle of rotation position of 0 ° of the cam disk or the output shaft thus relates in particular to a closed state of the door leaf.
  • the pointed area of the heart-shaped cam disk defines the angle of rotation position of 0 °, so that, based on this pointed area, corresponding angular areas of the cam disk can be defined.
  • the rotational angle positions and rotational angle ranges defined here thus also correspond to angular positions and angular ranges on the cam disk.
  • the cam disk is heart-shaped and has a pointed area, the pointed area being directed towards the second contact surface at a rotational angle position of 0 °.
  • a first restriction angle of rotation range is in particular between -10 ° and + 10 °, preferably between -5 ° and + 5 °. These values indicate upper limits for the described restriction angle of rotation range, which can also be smaller.
  • the first restriction angle of rotation range extends essentially over the tip area of the cam disk.
  • the corresponding configuration of the spacer arrangement ensures that the second contact surface is spaced apart from the cam disk in the first restriction angle of rotation range and the surface pressure is accordingly reduced here. This is particularly advantageous if the door operator is designed for an oscillating movement of the door leaf.
  • the door leaf With the swinging movement of the door leaf, the door leaf can swing back and forth or be moved beyond its closed position.
  • the cam disk moves through the 0 ° position in an oscillating movement, which would always result in a very stressful contact with the second contact surface without the spacer arrangement according to the invention.
  • the cam disk is heart-shaped and has the recess area, the center of the recess area being directed towards the second contact surface at a rotational angle position of V.
  • V lies between 120 ° and 240 °.
  • the spacer arrangement is preferably designed for a second restriction angle of rotation range which lies between V -45 ° and V + 45 °, preferably between V -30 ° and V + 30 °.
  • upper limits are again given for the second restriction angle of rotation range, it also being possible for the second restriction angle of rotation range to be smaller.
  • the spacer arrangement comprises at least one spacer element, the spacer element being linearly guided in one of the two movement elements.
  • the spacer element is designed in such a way that it strikes this movement element, in which it is guided in a linearly movable manner, in the restriction angle of rotation range.
  • the spacer element can also be guided so as to be linearly movable on both movement elements and then correspondingly strike both movement elements in the restriction angle of rotation range.
  • the spacer element is guided in a linearly movable manner on only one movement element and is firmly connected to the other movement element.
  • At least two of the spacer elements are provided. These two spacer elements then simultaneously also serve to prevent the two movement elements from rotating relative to one another. However, such a security against rotation can also be achieved with only one spacer element; for example if the spacer element does not have a round cross-section in its linearly guided area.
  • the at least one movement element in which the spacer element is guided in a linearly movable manner preferably has a recess.
  • the spacer element is inserted in this recess and is accordingly guided in a linearly movable manner in the recess.
  • the spacer element has a shoulder. This paragraph serves as a stop and strikes the moving element in order to limit the minimum distance.
  • the at least one spacer element is designed here in particular as a rod.
  • the rod can be firmly connected in one of the two fastening elements, for example by means of a thread or a press fit.
  • the rod is linearly moveable in a hole in the movement element.
  • the two spacer elements are arranged on two different sides of the output shaft.
  • the imaginary output axis around which the output shaft rotates thus runs between the two spacer elements.
  • the spacer arrangement comprises a spacer cam disk on the output shaft and a spacer element.
  • the spacer cam disk has a different contour than the cam disk described above.
  • the spacer cam disk can directly adjoin the cam disk or be spaced from the cam disk.
  • the spacer element is located on the second movement element.
  • the spacer element is firmly connected to the second movement element or is formed integrally with the second movement element.
  • the spacer element according to this second variant does not extend as far as the other movement element, but only as far as the spacer cam disk.
  • the spacer cam rests against the spacer element.
  • the contour of the spacer cam disk is designed in such a way that it has no contact with the spacer element in the free angle of rotation range, but only comes into contact with the spacer element in the at least one restricted angle of rotation range.
  • the spacer element and the spacer cam disk are arranged and designed in such a way that the cam disk and the second contact surface are spaced apart from one another in the restriction angle of rotation range.
  • the door operator includes an additional anti-rotation device between the two movement elements.
  • This anti-rotation device can be formed, for example, by at least two rods.
  • the rods are guided to be linearly movable in at least one movement element and have no stops, so that the rods only ensure anti-rotation protection, but no distance restriction between the two movement elements.
  • the rods of the anti-rotation device can run in a constriction of the output shaft between the cam disk and the spacer cam disk.
  • the radius at the pointed area of the spacer cam disk is larger than the radius at the pointed area of the cam disk. Due to this relatively large radius at the tip area of the Spacer cam disk, an excessive surface load between the spacer cam disk and the associated spacer element is avoided.
  • the radius at the pointed area of the spacer cam disk is at least 20% larger than the radius at the pointed area of the cam disk.

In this position, the door leaf is in particular in its closed position. Accordingly, this angle of rotation position of the door leaf and the output shaft 4 and the cam disk 5 is described as 0 °.
  • a first restriction angle of rotation range 33 is defined. This first restriction angle of rotation range 33 extends in particular over the pointed area 30 of the cam disk 5.

  • the spacer element 21 and the spacer cam disk 38 are designed and arranged here in such a way that they touch in the first and second restricting rotational angle range 33, 34 and thereby restrict the distance 32. In the two free rotation angle regions 35, there is no contact between the spacer element 21 and the spacer cam disk 38.
  • the spacer element 21 simultaneously fulfills the function of the bolt 17, since the spacer element 21 is arranged in such a way that it secures the roller shaft 18 of the second roller 13 from falling out.
  • Figures 9 to 11 show representations in a plane perpendicular to the output shaft 3 for the second exemplary embodiment.
  • Fig. 9 shows the first restriction angle of rotation range 33.
  • the spacer cam 38 and the spacer element 21 are in contact and limit the distance 32 so that the distance 36 between the second contact surface 12 and the cam disk 5 occurs.
  • Fig. 10 shows one of the two free rotation angle ranges 35.
  • both contact surfaces 7, 12 are in contact with the cam disk 5.
  • the spacer cam disk 38 and the spacer element 21 do not move.
  • Fig. 11 shows the second restriction angle of rotation range 34, in which the distance 36 is again set by a contact between spacer element 21 and spacer cam disk 38.
  • the spacer cam disk 38 is also designed in the shape of a heart and accordingly has a pointed area and an opposite indentation area.
  • a radius 39 at the pointed area of the spacer cam disk 38 is preferably designed larger than a radius 40 at the pointed area 30 of the cam disk 5.
