Definitions

  • the invention relates to a swing door with a spring-operated door closer.
  • the pivot axis of the door closer coincides with the pivot axis of the swing door. Due to the spring characteristics of the spring-of the door closer, the closing force of the door closer increases with conventional swing doors as the opening angle of the swing door increases. However, this is undesirable because the person or the object (trolley or the like) with which the swing door is opened must exert an increasing force to open the swing door in the course of the opening movement. On the other hand, it is desirable if the closing force of the door closer is greatest in the closed position of the swing door, namely in order to prevent the swing door from being opened unintentionally in this position, for example by the wind pressure.
  • Another disadvantage of known swing doors is that their opening angle is limited to approximately 100 °. However, this is not sufficient for many applications, especially if transport routes lead laterally behind the swing door.
  • the invention avoids these disadvantages. It is based on the task of proposing a swing door with a spring-operated door closer, which is characterized by a large opening angle and a closing force which at least does not increase, preferably decreases, with an increasing opening angle.
  • the invention is characterized in that the pivot axis of the door closer is offset inwards relative to the pivot axis of the swing door, that a pair of spring tension levers of the door closer rests on a roller such that the swing door is acted upon in the closing direction, and that either the roller on the lintel and the door closer on the swing door or the roller on the swing door and the door closer are attached to the lintel.
  • the lever arm between the momentary contact point between the roller and the relevant spring tension lever of the spring tension lever pair and the pivot axis of the door closer increases with increasing opening angle of the swing door. This effect would not be achieved if the pivot axis of the door closer coincided with that of the swing door, as is the case with the prior art.
  • the spring of the door closer can be dimensioned for each size of a swing door so that the desired closing pressure is achieved in each case. There is therefore also a significant economic advantage such that only one closer is required for a swing door. In the prior art, however, two or more door closers had to be used for larger swing doors in order to apply the necessary closing pressure. Due to the distance between the two pivot axes, a significantly larger opening angle of the swing door is also achieved. Depending on the embodiment, this is 135 to 150 °, calculated from the closed position of the swing door.
  • Swing doors with a swivel range of up to 180 ° are already known, which is achieved by a combined spring hinge with two swivel axes per door leaf, but these swivel doors do not have the novel spring characteristics and are also structurally complex.
  • the spring tension levers forming the pair of spring tension levers have recesses into which the roller engages in the rest position of the swing door.
  • the measures according to claim 5 and 6 make it possible in a structurally simple manner to lock the door wing or doors in question in the open state if necessary.
  • the opening angle of the swing door, at which it is locked, depends on the point at which the stop is locked along the spring tension lever.
  • a swing door 1 is pivotally attached to a frame 3 via hinges, of which only the upper hinge 2 is shown in FIG. 1.
  • the pivot axis of the swing door is labeled position 4.
  • a spring-operated door closer 5 has a pivot axis 6. Its spring is indicated at position 7. The spring force can be adjusted in a known manner via a threaded nut 8 with which a locking nut 9 cooperates.
  • the spring 7 acts on two spring tension levers 10, 11, which form a pair of spring tension levers. Both spring tensioning levers are compressed by means of the spring 7, so that they are in the rest position of the swing door shown in the drawing on one Roll 12 are present. This is rotatably attached to the upper horizontal part of the frame 3 or to the upper lintel. In the rest position shown, the roller 12 lies in recesses 13 of the spring tensioning lever.
  • an extension 14 is also attached, in which two threaded screws 15 are screwed one above the other, of which only one is shown in the drawing.
  • the spreading of the spring tensioning levers 10, 11 and thus also the position of the swing door relative to the frame are adjusted by a corresponding adjustment of the threaded screws.
  • the roller 12 migrates out of the recess 13 of the spring tension lever 10 or 11 in question in the direction of the arrow 17. This increases the lever arm between the current contact point between roller 12 and spring tension lever 10 or 11 - in FIG. 2, this contact point is the center of the recess 13 - and the pivot axis 6 of the door; Closer 5. Due to this increasing spring arm, the closing force exerted by the spring 7 remains at least the same when the swing door opens. It preferably decreases as the opening angle increases.
  • roller can also be rotatably fastened on the upper edge of the door leaf of the swing door 1, in which case the door closer is then fastened to the lower edge of the lintel with its spring tension levers.
  • the swing doors described are usually arranged in pairs.
  • the distance between the pivot axes 4 and 6 depends on the particular circumstances. The greater this distance, the greater the effect that can be achieved with the invention, i.e. the restoring force exerted by the door closer on the swing door is influenced more depending on the opening angle of the swing door.
  • Fig. 3 the swing door is attached to an angle profile 18.
  • the opening angle of 150 ° is also shown there.
  • a stop 19 serving as a arrester is pushed onto each of the spring tensioning levers 10, 11 and locked at the desired point along the spring tensioning lever, for example by means of a screw.
  • the door leaf can be locked in the open state if necessary.
  • the stops 19 are infinitely adjustable on the spring tension levers. On their side facing the pivot axis 6 of the door closer they have a flat overrun profile 20 and on the opposite side a steeper overrun profile 21.
