  • the invention relates to a device for braking and Determine a swing wing or a swing wing, with two, having an intermediate brake Telescopic members, with a telescopic member on a fixed Frame and the other telescopic member is attached to the wing, and the telescopic members of one telescopic arm and one Telescopic tube are formed, the telescopic arm over the Brake is slidably guided in the telescopic tube, and that Telescopic tube with a thickened area has a slightly larger cross section in which the Brake is inactive or less active.
  • EP-A2-723 058 is a brake for one Skylight wings become known, which the opening of the Skylight wing allowed in a ventilation position, with a further pivoting of the skylight wing over the Release position also applies the braking effect.
  • the vent position is only around pivoted an angle of about 30 °.
  • the Cleaning position that is, when fully open Fanlight wing, this has an opening angle of 70 ° - 90 ° on.
  • the brake is active in the cleaning position. With bottom-hung wings must apply the brake relatively early, otherwise that the tilting moment occurring on the tilted sash becomes too large.
  • the invention has for its object a device for braking and locking a wing or one To provide swing or reversible wing, which opened easily and without additional force and can be closed, however, the wing in the area braked and held to its maximum open position becomes.
  • This task is the beginning of a device mentioned type solved according to the invention in that the Telescopic arm and the telescopic tube in this way on the frame and sash are attached and the thorned area selected in this way is that the braking effect is no more than 30 ° before the maximum open position of the wing.
  • a rotary wing can or a swing wing as before and with the same force opened and up to the area of its maximum Open position can be pivoted. Only when the wing Reached its maximum open position, the Brake active and the swinging movement is braked. An in this opening area is located on the wing Brake also held in its current position, so that the brake also serves as a locking device and the For example, wings are not swiveled by drafts. Inadvertently inclined wings are also in this Open position held.
  • the preferred braking range is at 15 ° to 20 ° before the maximum open position.
  • the braking effect starts at an opening angle of 80 °.
  • the angle between its closed position and one Opening angle of 80 ° moved without additional effort so that the brake for one in this angular range User is imperceptible.
  • a preferred embodiment provides that the Telescopic tube over at least 30% and especially over 50% its entire length is thorned. In this thorned out The brake is moved over the telescopic arm, however, it does not apply braking forces to the telescopic tube. By changing the thorned area, in particular by extending it, the opening angle range, in which the brake is not active, changed, in particular be enlarged.
  • the articulation point is preferably the one articulated on the frame Selectable telescopic link on the frame.
  • the location of the articulation point on the frame is also the Opening angle range in which the brake is not active is changeable. In this way, the onset of Brake should be chosen so that the momentum is one opening wing is definitely slowed down before this reaches its maximum open position and on the frame or another component. Choosing the correct one The articulation point can be carried out on site during assembly be, the articulation point then fixed or can be changed later.
  • articulation points are preferably provided on the frame, so that via these articulation points the Opening angle at which the braking effect should start can be selected. This is especially so required if there are structural changes or if the permissible opening angle range of the wing changed.
  • One embodiment provides that the frame side Bearing the articulation point displaceable with respect to the frame is. By moving the pivot point on the frame is one stepless or continuous change of the braking range possible so that the setting can be optimized.
  • the bearing is preferably in two parts and has one with the Telescopic link connected slide or a plug element on. With such a bearing, the braking angle can even changed and discontinued by laypeople. The involvement is no longer required by specialist personnel.
  • the device according to the invention with a rotary wing on the upper frame spar and on an upper wing section is attached.
  • a swing wing that is Device according to the invention preferably above the Swing axis attached to the frame and sash.
  • Figure 1 is a frame 1 in section Rotary casement window 2 reproduced, with a casement 2 via a bearing 3 with a vertical bearing axis 4 in the direction of Arrow 5 is pivotally mounted.
  • the in Figure 1 shown position of the rotary wing 2 is the closed position.
  • FIG. 2 is the maximum open position of the rotary wing 2 shown.
  • the maximum opening angle is this Embodiment about 90 °, it can with others However, embodiments may also be larger or smaller.
  • a handle is indicated by reference number 6, with which the rotary wing 2 can be locked and unlocked.
  • FIGS. 1 and 2 is on the rotary wing a first telescopic bearing 7 fastened by means of screws 8, a first telescopic member 9, namely at the telescopic bearing 7 a telescopic tube 10 is pivotable about a pivot axis 11 is attached.
  • a sliding second telescopic member 12 namely a rod-shaped Telescopic arm 13 out.
  • a brake which is shown in Figures 3 to 5 in more detail is shown.
  • the telescopic arm 13 is a second Telescopic bearing 14 attached to the frame 1.
  • This telescopic bearing For example, 14 is at the top, not shown Frame spar screwed on with appropriate screws.
  • This second telescopic bearing 14 is preferably in two parts The first part with the frame 1 is connected and the second part at the end of the telescopic arm 13 is set. By moving the two bearing parts against each other, the pivot axis 15 for the telescopic arm 13 relocated with respect to the frame 1 and thereby the location the telescopic members 9 and 12 relative to the frame 1 and the Rotary wing 2 can be changed.
  • the telescopic tube 10 has a thorned area 16, compared to a braking section 17 slightly has a larger cross section.
  • the in the telescopic tube 10 over the telescopic arm 13 guided brake is thorned Area 16 is inactive and only exerts its braking effect in the braking section 17.
  • By changing the Aspect ratio between the flared portion 16 to Brake section 17 can be selected to start braking, which means that the opening angle can be determined at which the effect of the brake begins. Between the Closed position, which is shown in Figure 1, and this Brake angle is not active, whereas between this opening angle and that in FIG. 2 shown maximum open position, the brake 18 acts.
  • FIG. 3 From Figure 3 it can be clearly seen that one end of the Telescopic arm 13 on a bearing piece 19 of the telescopic arm 14 is pivotally fixed.
  • the bearing connection is in against accidental axial loosening secured.
