Definitions

  • the present invention relates to a door operator, in particular a door closer, for operating a door.
  • Door actuators are to be understood in particular as door closers, servo door closers and door drives.
  • door closers an energy store is usually preloaded by manually operating the door leaf. By unloading the energy store, the door can be closed again without manual operation.
  • the door closers are either attached directly to the door leaf, on a door frame or on the wall. When attached to the door leaf, a linkage is attached to the output shaft of the door closer. The force is transferred to the wall or frame via this linkage. When the door closer is installed on the frame or on the wall, the force is transferred to the door leaf via the linkage.
  • the problem with previously known door actuators with a cam drive is often the mounting of the cam with the output shaft in the limited space between the opening piston and the damping piston or closing piston.
  • a door operator according to the preamble of claim 1 is known from the US 5,901,412 A and from the DE 298 25 208 U1 known.
  • a door actuator for opening and / or closing a door, comprising a housing, an output shaft with a cam disk and a piston guided in the housing, which abuts the cam disk.
  • the output shaft comprises a first axle shaft mounted in the housing.

  • the cam disk and the first piston are designed in particular for converting a rotary movement of the output shaft into a linear movement of the piston.
  • the force of a closer spring acts on the first piston, for example.
  • the piston can also be moved hydraulically and the output shaft can thus be set in rotation via the cam disk.
  • the assembly of the door actuator is facilitated in that complementary parts of the first plug connection are formed on the axle shaft and on the cam disk. This means that the cam disc can be inserted first and then the axle shaft can be inserted.
  • the output shaft comprises a second axle shaft mounted in the housing and rotationally fixedly connected to the cam disk, the first and the second axle shaft being arranged on opposite sides of the cam disk.
  • the cam disk is supported on two opposite sides in the housing.
  • At least one of the two axle shafts protrudes outwards through the housing, so that, for example, a linkage for transmitting power to the door leaf or to the frame can be mounted on this axle shaft.
  • Both axle shafts preferably protrude outwards, so that, depending on the opening direction of the door, the linkage can be mounted either on the first axle shaft or on the second axle shaft.
  • the second axle shaft is connected to the cam disk in a rotationally fixed manner by means of a second plug connection.
  • the output shaft thus consists of three separate components, namely the cam disk, the first axle shaft and the second axle shaft.
  • the first and / or second plug connection preferably represents a positive connection between the cam disk and the first or second axle shaft.
  • the axle shafts can also be connected to the cam disk in a non-positive and / or positive manner.
  • welding preferably resistance welding, gluing or pressing of the components, is provided in particular.
  • the first plug-in connection comprises a first extension on the first axle shaft and a recess in the cam disk which is complementary to the first extension.
  • the first plug connection can have a first extension on the cam disk and a first recess complementary to the first extension in the first axle shaft.
  • the second plug connection can preferably comprise a second extension on the second axle shaft and a second recess in the cam disk that is complementary to the second extension.
  • the second plug connection comprises a second extension on the cam disk and a second recess complementary to the second extension in the second axle shaft.
  • An extension complementary to the recess is to be understood to mean that the extension can be inserted into the recess and thus enables a form fit between the axle shaft and cam disk in the direction of rotation of the output shaft.
  • each of the two plug connections can preferably comprise a plurality of extensions and, accordingly, a plurality of recesses.
  • the extensions and recesses can be arranged on the axle shafts as well as in the cam disc.
  • first extension and / or the second extension is designed as a polygon or with an oval cross section.
  • individual extensions can also be designed as pins with a round cross section.
  • the recesses are each designed so that the extensions can be inserted and a positive connection is created.
  • the door actuator comprises a second piston guided in the housing.
  • the first piston and the second piston are arranged on opposite sides of the cam disk and the first piston is fixedly connected to the second piston.

  • the cam disk has to be mounted between the first and the second piston, it is particularly advantageous that the first axle shaft and / or the second axle shaft only after the cam disk has been positioned in the cam disc are inserted.
  • the cam disk can thus be inserted laterally between the first and second pistons and the axle shafts are then inserted into the cam disk from above and below.
  • a damping piston is preferably provided, which is guided in a cylindrical cavity in the second piston, the damping piston resting on the cam disk. This damping piston dampens in particular a closing movement of the door leaf.
  • the first and the second axle shaft are preferably designed as identical components.
  • the outer side of the first axle shaft and / or the outer side of the second axle shaft particularly preferably has a polygon.
  • This polygonal connection is used to assemble the boom. The force is transmitted from the door closer to the door leaf or frame via the linkage.
  • the polygonal connection is designed as a square.
  • the geometry of the first plug connection and / or the second plug connection is such that when the first axle shaft and / or the second axle shaft is inserted, a defined position of the lateral edges of the polygon with respect to the position of the cam disk is created.

  • an outer surface of the damping piston bears against an inner surface of the cylindrical cavity, so that the damping piston is guided in a linearly movable manner in the second piston (cylinder element).
  • the fixed connection between the second piston (cylinder element) and the first piston (opening piston) means in particular that the second piston (cylinder element) has no degree of freedom compared to the first piston (opening piston).
  • the energy store comprises at least one closer spring.
  • the closer spring is designed in particular as a compression spring.
  • one end of the closer spring is supported directly against the end of the first piston (opening piston) facing away from the cam disk.

  • an outer surface of the second piston (cylinder element) is guided in the housing.
  • the outer surface of the second piston (cylinder element) is cylindrical.
  • the second piston (cylinder element) is thus supported inwards relative to the damping piston.
  • the second piston (cylinder element) is guided in a linearly movable manner in the housing and is therefore also supported in relation to the housing. Because the second piston (cylinder element) is fixed is connected to the first piston (opening piston), this double support of the second piston (cylinder element) also stabilizes the first piston (opening piston) and thus prevents tilting of the first piston (opening piston), which improves the efficiency of the door closer.
  • the output shaft with the cam disk is arranged between the first piston (opening piston) and the second piston (cylinder element). Since the first piston (opening piston) is firmly connected to the second piston (cylinder element) and the cam disk is located between the two components, the first piston (opening piston) is supported on both sides of the cam disk.
