DE8701005U1 - Window or door with seal - Google Patents

Description

The invention relates to a window or a door with a frame and a sash that accommodates glazing, as well as with a seal that is attached to the frame or sash and that, when closed, has a sealing surface that seals against the corresponding contact surface of the other element.

Seals for windows and doors are designed to seal against excessively high ventilation heat losses and against driving rain. In previous developments, an ever greater resistance to driving rain and a correspondingly high level of airtightness has been achieved through the arrangement and design of seals as well as through the multiple arrangement of seals. This means that even very simple window or door constructions today have a level of driving rain resistance that is only required for high-rise windows, whereby these constructions are resistant to normal external wind pressures of wind force 2 to 3, which are average values for the whole year.

have become almost airtight.

The complete air permeability of today's windows means that in many cases the desired air permeability of the window constructions is not guaranteed. This is particularly problematic in houses that are not thermally insulated/whose rooms are not sufficiently ventilated.

The innovation is based on the task of designing a window or door of the type mentioned at the beginning in such a way that the driving rain resistance is maintained up to a test pressure of 600 Pa, while at the same time the air permeability is increased to a total of 0.9 to 1.0 m^/h x m at 10 Pa, whereby a local air passage of no more than 0.1 m^/h x cm may occur.

To achieve this object, the invention proposes that the sealing surface has channels running transversely to its longitudinal direction, which are dimensioned and arranged in such a way that they allow a desired amount of air to pass through at a predetermined pressure, but prevent the passage of air.

The idea underlying the invention is unusual. By providing channels, the sealing effect of a sealing element is partially and specifically canceled. This solution makes it possible to retain the known designs and to create the desired conditions in accordance with the prevailing environmental conditions and the requirements.

The channels are comparatively small. Their relatively small cross-section holds back driving rain* but at the same time allows air to be exchanged*

Further features of the invention emerge from the further subclaims.

A preferred embodiment of the invention is described in detail below with reference to the drawing. The drawings show:

Figure 1 - a cross section through a frame and

adjacent window sash area of a known construction,

Figure 2 - a perspective view of a part of the seal,

Figure 3 - a very strong enlargement of the seal in the area of its sealing surface and the opposite contact surface.

The window sash 7 is constructed in a known manner, just like the frame 6, and therefore requires no explanation. A seal 4 is attached to the frame and its sealing surface 3 rests against a counter surface 5 of the sash 7.

The seal is shown in more detail in Figure 2.

The seal 3 has channels 1 running transversely to its longitudinal extension, which are arranged parallel to one another. The seal 4 rests against the counter surface 5 with the sealing surface 3 or partial area of this sealing surface. The formation of the adjacent areas can be seen in more detail in Figure 3:

A channel 1 has a width c and two ribs 2 on its edges. The seal 4 rests on the opposite contact surface with the ribs 2. The ribs protrude by the amount a from the adjacent area 3a, or the area 3a is pushed back by the amount a due to the projection of the ribs 2.

The ribs are inevitable during certain manufacturing processes of the channels.
