Definitions

  • the present invention relates to windows and doors, hereinafter collectively referred to as window element.
  • window element When subsequently speaking of a window element, so should always be meant either a window or a door.
  • the hollow box has an intermediate ceiling dividing the hollow box into a lower chamber and an upper chamber.
  • the intermediate ceiling ensures that air flowing in via the lower recess into the hollow box is deflected in a zigzag shape before it can flow out of the hollow box via the upper recess.
  • the articulation point of the flap is located in the region of that horizontally extending edge of the hollow box, which is diametrically opposite the already mentioned horizontal edge.
  • a respective length of the respective flap is greater than a respective upper distance of the respective pivot point from the edge of the respective upper recess farthest from the respective pivot point. However, the length is smaller than a respective lower distance of the respective articulation point from the edge of the respective lower recess furthest from the respective articulation point.
  • the articulation point is located outside the region between the respective lower and the respective upper recess, which contains the horizontally extending edge.
  • a ventilation element for installation in a window element wherein the ventilation element is designed as a hollow box which has a lower recess on a lower side near a horizontally extending edge and has an upper recess adjacent to an edge extending horizontally to this edge.
  • the ventilation element has no flap. The air flow passing through the ventilation element of the DE 297 21 460 U1 flows, is therefore unregulated.
  • a ventilation element for installation in a window element which is placed on a window frame of the window element.
  • the venting element has a substantially U-shaped cross-section which is open at the bottom.
  • a flap is pivotally mounted at a point of articulation, so that the flap between an open position and a closed position is movable.
  • the pivot point is located in the horizontal portion of the U-shaped cross section near the transition to the nearest leg of the U.
  • In the horizontal portion of the U can be arranged on the bottom part and the ceiling part webs, which force a meandering course of the air flow.
  • the solution according to the DE 102 40 290 B4 is relatively complicated.
  • the solution according to the DE 297 21 460 U1 is unregulated.
  • the solution according to the DE 297 17 061 U1 Especially with already installed window elements can be realized only with considerable construction effort.
  • the object of the present invention is to provide a ventilation element for installation in a window element and a window element with such a ventilation element, which avoid these disadvantages.
  • the ventilation element should be simple and reliable and can be used with window elements made of wood.
  • a window element of the type mentioned above is configured in that the ventilation element is designed as a ventilation element according to the invention.
  • the respective flap is acted upon by an air flow, which flows through the respective lower or upper recess in the respective hollow box and flows out through the respective upper or lower recess from the respective hollow box, with a pressure force which - based on the respective flap - is directed from the respective open position in the respective closed position.
  • the transfer to the respective closed position takes place when this pressure force is large enough.
  • the respective flap is in the respective open position when it is pivoted as far as possible to the respective lower recess, and in the respective closed position, when it is pivoted as far as possible to the respective upper recess. In some cases, however, the reverse procedure is realized.
  • the flap is mounted on the hollow box via respective bearing elements or a respective film hinge, which or a pivoting of the respective flap relative to the respective hollow box does not oppose the respective flap in a predetermined rest position restoring force.
  • This embodiment is particularly easy to realize. If necessary, a restoring force can be realized, for example by an additionally installed respective spring element.
  • the respective flap when it is pivoted as far as possible to the respective lower and / or upper recess, with the side wall forms a different angle from 0 °, so that the respective flap in the absence of an air flow moving away from the sidewall due to its gravity.
  • the ventilation element is arranged in this case on an upper side or a lower side of the window element.
  • the respective flap is connected to the respective hollow box via a respective connecting element, so that a pivoting of the respective flap relative to the respective hollow box causes an elastic deformation of the respective connecting element.
  • the respective connection element may be an independent element of the ventilation element.
  • the respective connecting element can be integrally connected to the respective flap.
  • the respective flap then, when it is pivoted as far as possible to the respective lower recess, viewed from the respective pivot point to the underside inclined to. This ensures that condensate, which can form due to temperature differences, runs off the respective flap and drips (within the respective hollow box) on the bottom.
  • the ventilation element also has an upper side.
  • a respective inner height of the respective hollow box - ie a distance of the underside from the top - in the region of the horizontally extending edge maximum and further decreases the respective inner height with increasing distance from the side wall strictly monotonous.
  • This configuration ensures that condensate, which forms within the respective hollow box on the bottom or dripping on the underside, runs on the bottom to the respective lower recess, so that they can escape from the respective hollow box there. In the installed state in the window element, this corresponds to the fact that the underside is inclined relative to the horizontal, so that the underside has its lowest point in the region of the respective lower recess.
  • the respective pivot point is located on the side wall and is spaced from the horizontally extending edge.
  • a particularly efficient deflection of the air flow can be effected.
  • the overall flow resistance of the respective hollow box can be minimized.
  • the respective flap is formed elastically at least in the region of their respective abutment point remote from the respective abutment edge.
  • a respective stop region of the respective hollow box, in which the respective flap bears in the closed position on the respective hollow box is designed to be elastic. This causes on the one hand a solid seal of the respective flow channel in the closed position and prevents the other a rattling or the like.
  • the respective flap is elastic as a whole.
  • the respective flap is elastic only in the region of the respective stop edge.
  • tolerances can be compensated by the respective flap when the ventilation element and thus the respective hollow box should forgive, for example due to temperature influences.
  • respective spacers are provided, by means of which a pivoting of the respective flap is limited to the underside before the respective flap rests on the underside. This can be achieved in a simple manner that the respective flow channel remains open even at low pressure differences between the inside and outside of the window element.
  • the respective spacers and / or the respective flap are elastically formed in a respective contact area in which they touch. As a result, rattling noises can be avoided.

  • the window element 2 can be opened.
  • the following statements always refer to the closed state of the window element 2.

In this case, the ventilation element 8 is identical to the hollow box. This embodiment will be explained below. In an embodiment in which the ventilation element 8 has a plurality of hollow boxes, will be discussed later.
  • the ventilation element 8 has an edge 9. As a rule, the edge 9 runs horizontally. The edge 9 is not adjacent to the frame 3, 4 in the installed state of the ventilation element 8, which has the stepped fold 5.

Due to the fact that the upper side 16 generally runs horizontally, an inner height h (ie the distance of the underside 10 from the upper side 16) in the region of the edge 9 is thus maximal. With increasing distance x from the side wall 11, the inner height h decreases strictly monotonously. It is possible that a wall thickness of the bottom 10 is uniform.
