Definitions

  • the invention relates to a door closer according to the preamble of claim 1.
  • Such a closer is known from DE-OS 33 45 004.
  • predetermined strokes adapted to the opening and closing characteristics are assigned by the design of the cam tracks, the spring support member and also the damping piston depending on the door opening angle or angle of rotation.
  • the cam track assigned to the fader support member permits a stroke assigned to the angle of rotation of the closer shaft.
  • DE-OS 20 41 099 shows a floor door closer in which the sliding member of a second damping device is secured against rotation. This protection against rotation is realized by a stop protruding into a groove. As a result, the sliding member cannot twist during an axial movement.
  • the object of the invention is to provide a door closer of the type mentioned, in which a rotation of the damping piston and the force transmission member about the longitudinal axis with respect to the cam disc is avoided, ie they must be able to move independently of one another in the axial movement. Likewise, the anti-rotation device must not have any influence on the cam disc used.
  • securing means are present which prevent the damping piston and the spring support member from rotating against one another.
  • the function of the door closer is in no way impaired by the attachment of the securing means.
  • Two rods are used as securing means, which are advantageous on the one hand e.g. are firmly anchored in the spring support member and, on the other hand, can smoothly plunge into blind bores on the opposite side within the damping piston.
  • the securing rods are arranged on each side of the closer shaft in the axial direction of the housing. This makes it possible that the locking rods are supported either on one or the other side of the closer shaft when the damping piston or the spring support member is rotated.
  • a round bar can be positively and positively e.g. anchor within the spring support member or the damping piston. On the opposite side there are free bores in which these round bars can dip without friction when the door closer is actuated.
  • the locking pins thus represent a rotation lock of the pistons with respect to the cam disc. This always ensures that the piston or the spring support member remain in their original position. If the spring support member or the damping piston are brought out of their original position, the rollers can no longer come into engagement with the cam disc properly. There is a pushing and rubbing, which results in increased wear of the door closer. Also, the degree of damping of the door closer is no longer correct when the damping piston or the spring support member is turned, because other forces are used within the door closer. When the spring support member is rotated, the force curve from the spring via the roller to the cam disc is significantly worse, and the required closing torques are no longer provided, which may not ensure that the door is closed securely.
  • the section (1) of the door closer shown in FIG. 1 has been shown in section.
  • the closer shaft (2) is located inside the housing (1).
  • the cam disc (3) is non-positively and positively connected to the closer shaft.
  • Both the roller (13) and the force transmission roller (14) are in contact with the cam disc (3) via spring forces that lie behind the damping piston (10) and the spring support member (20).
  • the roller (13) is located within the damping piston (10) and is rotatably supported in the damping piston (10) by an axle bolt (11).
  • the power transmission roller (14) is also rotatably mounted within the spring support member (20) by means of an axle bolt (12).
  • a force is transmitted against the spring support member (20) via the pressure spring (15) via the force transmission roller (14) to the cam disc (3).
  • a spring (21) is also located behind the damping piston (10).
  • two securing rods (8) are located within the spring support member (20). These locking bars run in the longitudinal axis of the closer housing and transverse to the closer shaft (2). They are firmly connected to the spring support member (20) via a non-positive and positive connection (18). This can happen, for example, in that heavy-duty locking pins are provided as securing rods (8), which sit with a press fit in the spring support member (20). It would also be possible to press them into the damping piston (10). It is crucial for the function of the safety rods (8) that they close to the closer shaft (2) To have position. They therefore run with appropriate play directly above the cam disc curve (3) and directly past the two sides of the longitudinal axis of the closer shaft (2).
  • the closer shaft extension (9) is required to support the deep groove ball bearing located in the sealing plug (6), but not shown. In the area of the security rods (8), this shaft extension is interrupted by a groove to make room for the security rods (8). This measure ensures that the spring support member (20) cannot rotate with respect to the cam disc (3). The spring support member (20) would not change its position in relation to the cam disc (3) by either a right or a left turn.
  • the locking rods (8) are made long enough so that they can be immersed smoothly with a clearance fit within the damping piston (10) in two blind holes (16).
  • the depth and length of the blind bores (16) are dimensioned such that a sufficiently large free space (17) remains between the inserted safety rod end (19) and the end of the blind bore (16).
  • This free space (17) must be dimensioned so deep that during the longitudinal movements of the damping piston (10) and the spring support member (20) the safety rods (8) do not stop (10) within the damping piston.
  • the aforementioned blind bore (16) can also be present within the spring support member (20). It is important that at least two rods are used, because if only one rod were used, the damping piston (10) and the spring support member (20) might only be secured against one direction of rotation.
  • round materials have been used as securing rods (8). These round bars or pins represent an inexpensive fuse and are also easy to handle when manufacturing the door closer. Square materials or other materials can of course also be used just as well.
