Definitions

  • the present invention relates to a door operator for opening and / or closing a door leaf.
  • the prior art knows various types of door operators, in particular door closers, power door closers or door drives.
  • the door operator is attached either directly to the door leaf or to the wall or frame. If the door operator is on the wall or frame, an output shaft of the door operator is connected to the door leaf via a linkage. If the door operator is located directly on the door leaf, the linkage connects the output shaft with a slide rail on the wall or frame.
  • the rotational movement of the output shaft is converted by means of pistons into a linear movement for tensioning a closing spring.
  • the linearly guided pistons are integral rotary milled parts.
  • a door operator comprising a housing and a rotatably mounted in the housing output shaft.
  • the door leaf is actuated via the output shaft.
  • the door operator For example, on the door leaf, the force is transmitted to the frame or a wall via the output shaft and a linkage. If the door operator is on the wall or the frame, the force is transmitted to the door leaf via the output shaft and a corresponding linkage.
  • the output shaft can be arranged coaxially to the axis of rotation of the door. It requires no linkage for power transmission.
  • the door operator according to the invention further comprises at least one piston guided linearly in the housing.
  • the piston cooperates with the output shaft, so that a rotational movement of the output shaft can be converted into a linear movement of the piston, and vice versa.
  • the piston is constructed in two parts and thus comprises a first component and a second component.
  • the first component has a cylindrical receiving surface.
  • the second component is tubular and attached to the cylindrical receiving surface.
  • the firm connection between the two components is preferably carried out by a press fit and / or by shrinkage of the second component. Additionally or alternatively, a bonding, soldering or welding of the two components is possible.
  • an outer surface of the first component and / or the second component is guided on an inner surface of the housing.
  • a pressure roller is preferably rotatably mounted.
  • a bolt is rotatably received in the first component.
  • the pressure roller is rotatably mounted on the bolt.
  • a cam disc On the output shaft of the door operator, a cam disc is preferably arranged.
  • the arranged in the piston pressure roller rolls on the Cam disc off. Due to the contour of the cam disk, the piston is moved linearly during a rotation of the output shaft.
  • the first component of the piston is preferably a turned and / or milled part. It is in the first component to a very stable and precisely manufactured component in which in particular the pressure roller can be accommodated.
  • the tubular second components is designed in particular thin-walled.
  • the wall thickness of the second component is preferably between 1 mm and 10 mm, particularly preferably between 2 mm and 8 mm.
  • the second component is formed as a deep-drawn part.
  • the second component has a "pot shape”.
  • the lateral surface of this pot shape forms the "tubular" section, which is guided on the inner surface of the housing.
  • With the open side of the deep-drawn part is attached to the receiving surface of the first component.
  • the second component has an internal cavity.
  • a volume body also: volume compensation body
  • the solid is in particular cylindrical.
  • the cavity is preferably used as a hydraulic tank and / or hydraulic compensation chamber.
  • This use of the cavity is independent of the volume used, since despite the volume body a corresponding cavity can remain.
  • the cavity is preferably used as a tank or compensation chamber for hydraulic oil. This increases the system security, since due to sufficient tank or compensating volume, for example, with different oil fillings and temperature differences, a burst in the door operator is avoided.
  • at least one hydraulic line leads into the cavity.
  • the door operator has two pistons guided linearly in the housing.
  • only one of the two pistons or both pistons can consist of two components according to the present invention.
  • the one piston is used as a "damping piston” and displaces an oil volume to dampen the movement of the door leaf.
  • the second piston is used as a "closing piston” and cooperates with an energy store, in particular a spring.
  • Both pistons have a pressure roller that rolls on the cam.
  • the cam disk is located between the two pistons and thus between the two pressure rollers.
  • the two pistons are connected to each other via at least one connecting element.
  • This connecting element is preferably designed as one or more rods.
  • the rods extend beside or below or above the cam disc between the two pistons.
  • the at least one connecting element is preferably fastened directly to the first component of the respective piston.
  • Fig. 1 shows the structure of a door operator 1 for both embodiments. Based on Fig. 2 to 4 the first embodiment will be explained. Fig. 5 shows the second embodiment.
  • the door operator 1 has a housing 2.
  • an output shaft 3 is rotatably mounted in the housing 2.
  • the output shaft 3 is connected, for example via a linkage, with the door leaf.
  • a cam disk 4th On the output shaft 3 is a cam disk 4th
  • a first piston 5 On one side of the cam disk 4, a first piston 5 is arranged, on the other side of the cam disk 4, a second piston 6 is arranged.
  • the two pistons 5, 6 are guided in the housing 2 linearly movable.
  • each piston 5, 6 each have a pressure roller 7 is arranged.
  • the pressure rollers 7 are rotatably mounted on bolts 13.
  • the bolts 13 are rotatably received in the piston 5, 6.
  • damping chamber 8 Between a front side of the housing 2 and the first piston 5 is a damping chamber 8.
  • This damping chamber 8 is filled with hydraulic oil filled.
  • the hydraulic oil is displaced in the damping chamber 8, so that a damping of the movement of the door leaf is achieved.
  • the second piston 6 is operatively connected via a freewheel assembly 9 with a closing spring 10.
  • the closing spring 10 could also rest directly on the second piston 6.
  • Present door operator 1 is designed as a door closer.
  • the output shaft 3 and thus the cam plate 4 is set in rotation.
  • the two pressure rollers 7 rest on the cam disk 4, so that the two pistons 5, 6 are moved by a rotation of the cam disk 4.
  • the two pistons 5, 6 are moved to the right, so that the closing spring 10 is tensioned.
  • the closing spring 10 relaxes and moves the pistons 5, 6 to the left. This leads to an opposite rotation of the cam disc 4 and output shaft 3 and consequently to a closing movement of the door leaf.
  • the second piston 6 can be constructed analogously to the first piston 5.
  • Fig. 2 shows an isometric view of the first piston.
  • Fig. 3 shows a section through the first piston.
  • 5 Fig. 4 shows only individual components of the first piston. 5
  • the first piston 5 is composed of a first component 11 and a second component 12.
  • first component 11 In the first component 11 are connecting elements 15, formed as rods, attached. By means of these connecting elements 15, the two pistons 5, 6 are interconnected. Furthermore, the first component 11 has two aligned bores 22. In these holes 22 of the bolt 13 is received. On the bolt 13, the pressure roller 7 is mounted. For this purpose, 13 needle-shaped rolling elements 17 are located between the pressure roller 7 and the bolt.
  • the first component 11 is formed as a rotary milled part.
  • the first component 11 has a cylindrical receiving surface 19.
  • the cylindrical receiving surface 19 is adjacent to a stop 21 to a cylindrical collar 20.
  • the stopper 21 is formed between the receiving surface 19 and the collar 20.
  • the second component 12 is designed tubular.
  • the second component 12 is a deep-drawn part.
  • the second component 12 is attached to the receiving surface 19 with a press fit.
  • the outer surface of the second component 12 forms the guide surface, which is guided on the inner surface of the housing 2. Additionally or alternatively, it is also possible to use the outer surface of the collar 20 for guidance.
  • the holes 22 for the bolt 13 are at least partially set by the receiving surface 19. As a result, the bolt 13 is secured by attaching the second component 12.
  • Fig. 3 and 4 show that in the bottom of the deep-drawn second component 12, a closure element 14 is inserted.
  • This closure element 14 can also be used to guide a further component.
  • the second component 12 has a relatively small wall thickness 18.
  • the wall thickness 18 is between 1 mm and 10 mm.
  • a volume body 16 is inserted into the cavity of the second component 12.
  • the volume body 16 has a cylindrical recess.
  • the bulk body 16 is preferably made of an elastic material, e.g. from a soft closed-cell kautchuk.
