Definitions

  • the invention relates to a door closer with the features of the preamble of Claim 1.
  • a door closer device shown in SE-A-469 342 consists of a housing in which two pistons are movably arranged.
  • the first piston interacts with a closer shaft, the drive axis of which a linkage is connected to a door.
  • the diameter the two pistons are different.
  • the first piston is included connected to a piston rod, the rear end in a central bore of the second piston is sealingly received. About the pistons Fluid flow of the damping medium through different channels in connection controlled with valves.
  • a method and arrangement for controlling the force of a locking device can be found in DE 35 35 506 A1.
  • the door is opened using a Locking device in the form of a door closer and articulated to one another connected linkage arms connected to the door frame.
  • the control of the different forces to open and then automatic closing the door is relocated compared to the door locking device distal end of the linkage to the from the locking device on the Door exerted moment in separate phases of opening and closing the Door, changed accordingly.
  • This arrangement is concerned is a device that works with external energy, i.e. it is an electric motor provided that shifts a slide and at the same time its position in one Leader determined.
  • the engine control system is designed accordingly desired opening angle.
  • US 4,979,261 discloses a door closer with a variable articulation position. Due to a gear wheel attached to the closer shaft, which the door rolls, the linkage's point of attack and thus the entire moment consideration changed. This mechanical way achieved a reduction in the opening force, while increasing the Closing force.
  • a device that opens a door with a linear force shows the US 4,231,192.
  • a corresponding lever system in connection with an external energy in the form of a voltage supply is almost linear Course of the force at the door depending on the opening angle achieved.
  • DE-OS 32 34 319 was a solution to reduce the opening moment known in which the higher clamping force required by external energy for a spring preload is applied. With this solution, the additional Spring preload via both an electric motor and a piston be generated with a pressure medium circuit generated by external energy.
  • the object of the invention is to improve a door closer in that that for a high closing torque when opening the door, however, a low one Opening torque is required. No external energy should be used for this as some prior art solutions use it, and at the same time such a door closer should be inexpensive to manufacture and also be easy to assemble.
  • the object of the invention is achieved in that the normally existing fixed coupling between the opening and the closing force is released, by providing that the door closer at least depending on the path and direction two different translations and therefore different moments has and thus in this way the fixed coupling between Opening force and closing force is canceled.
  • Removing the fixed coupling is achieved in that in addition to the existing door piston spring piston acted upon by the closing spring is present.
  • the opposite a normal door closer creates additional pressure rooms are on the one hand through fixed channels, but on the other hand through controlled channels or throttles and valves connected to the damping medium.
  • By creating and connecting at least one hydraulic The second transmission can control the power transmission.
  • both the spring piston as well as the door piston in an L-shaped design.
  • a hydraulic damping and switching means can thus be used targeted and conscious damped movement of the door piston and the spring piston realize. This is done according to a procedure to be determined a control performed.
  • Such a method can, for example, in run out of shape that when opening the door, what manually or by a power-operated drive can happen, and the subsequent Closing process, which is solely due to the stored in the spring memory Energy becomes possible up to a certain and thus individually selectable door opening angle.
  • the spring piston and the door piston through a pressure equalization between all with the hydraulic fluid move the filled piston chambers at the same speed.
  • a control can only be activated from a certain opening angle of the door be activated, which separates the door piston from the spring piston causes.
  • FIG. 1 shows the schematic separation of the spring piston 2 from the door piston 3 reproduced. This separation creates an additional one Room 25th between the spring piston 2 and the door piston 3 lies, and is also filled with hydraulic fluid. So there are three Pressure medium chambers, namely a spring chamber 21, a door piston chamber 24 and the room 25.
  • the door piston chamber 24 is via a channel 53 constantly connected to the spring chamber 21.
  • another piston which is formed, for example, by a pinion cage can be. creates the inner piston 10, which in turn two further pressure medium spaces, namely an inner piston space 26 and one Inner piston chamber 27. creates.
  • the inner piston space 26 is through a channel connected to room 25.
  • the inner piston chamber is also 27 pressure medium connected by a channel to the door piston chamber 24.
  • the inner piston chamber 26 with a channel the door piston chamber 24 are connected. and the inner piston space 27 with room 25.
  • FIG. 5 shows a basic structure of the above-described approach played.
  • a housing 5 inside a housing 5 are the door piston 3 and the spring piston 2 arranged.
  • the spring piston 2 will from the spring 1. which acts as an energy accumulator. applied.
  • the spring 1 is supported on the other hand on the side wall 117 of the housing 5.
  • a toothing 4, which with a pinion cage, the one with a drive shaft protruding outside the housing 5 is connected for the active.
  • the linkage is attached to this drive axle on the one hand. with the other free end of the linkage for actuation the door, either hinged to the door or to the door frame.
  • the prior art is the fixed coupling between the spring 1 and the door piston 3 not available. Rather, here is through the intermediary of a hydraulic transmission. namely by the spring piston 2, the door piston 3, the housing 5 and through this with the Damping medium filled hydraulic rooms. namely the spring chamber 21, the piston chamber 22, the piston chamber 23 and the door piston chamber 24. formed.
  • a channel 42 in the spring piston 2 connects the piston chamber 22 to the spring chamber 21 via a pocket 61 in the door closer housing 5.
  • a channel 41 also bridges the piston chamber 23 with the door piston chamber 24 via a pocket 63 be said that the length of a pocket is above it. when a pressure medium room is connected to another or closed.
  • the connection described above makes it clear. that the door piston 3 and the spring piston 2 are hydraulically ineffective. so that there is a direct coupling between the spring 1 and the door piston 3 by contact of the surfaces 11 with the surface 101 and the surface 12 with the surface 13.
  • the overpressure which arises inside the housing, namely in the piston chamber 24, is thereby compensated for by underpressure in the spring chamber 21. that a channel 44 is always open between the two rooms.
  • the door (not shown) is still in the area c of the closing angle.
  • FIG. 10 The last part of the closing process is shown in FIG. 10.
  • the door is closed and the door piston is in its closed position Z, which is in the housing before the stop, arrived.
  • the contact between the spring piston 2 and the door piston 3 is not yet made.
  • Check valve 71 of the spring piston 3 a pocket 64, the channel 45 and a channel 48 switched through so that a connection between the piston chambers 22 and 23 comes about.
  • This is it possible that the contact between the spring piston 2 and the door piston 3 is restored.
  • Due to the strong throttling via a throttle 65 which is preferably located in the door piston 3, however at the same time prevents the high pressure in the piston chamber 23 from dropping.
