Description

Door sill arrangement

Technical field

The invention relates to a door sill arrangement, in particular to a door sill consisting of a sill body and sealing means arranged on a door leaf, wherein the sill body consists of two profile sections, the first profile section being located on the inner side of the door separating the inner and outer space while the second profile part is located on the outside, a connecting profile of thermally non-conductive material is inserted between the two profile parts.

BACKGROUND OF THE INVENTION

Door sills are well known. These thresholds are usually made of metal, especially aluminum. The main disadvantage of these door sills is their insufficient tightness against heavy rain, drafts and their low thermal and acoustic insulation.

DE 295 03 698 U1 discloses a one-piece door sill, which

2ϋ is connected to the door frame on both sides by means of fasteners. DE 43 10 013 C2 discloses a door sill profile with a fastening chamber and a cover strip. DE 198 14 968 A1 discloses a door sill consisting of a lower and upper part, including a seal located on the outside of the door sill, whereby the possible air flow between the lower and upper part of the door sill is effectively removed so that in this area chambers are provided which serve as insulating air spaces. DE 198 19 366 A1 discloses a door sill provided with a sheet for draining water. Another door sill with insulating properties is described in DE 198 43 736 A1. This wheelchair-accessible door sill is suitable for disabled people and consists of a thermal insulation and water drainage profile made of different materials.

DE 195 04 924 A1 discloses a door sill profile consisting of two parts, of which the first part is located on the inside of the door, while the second part is located on the outside of the door, the two door sections of the door sill being thermally connected to each other. insulating connecting element,

It is apparent from the prior art that the known door sills do not guarantee sufficient sealing against heavy rain and air flow.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to overcome the disadvantages of known door sills and to provide such a door sill arrangement which achieves a perfect seal against moisture, particularly heavy rain, and which also exhibits good thermal insulation between interior and exterior.

The advantages achieved by the present invention are that the proposed door sill arrangement simply guarantees thermal separation of the interior space from the outside space and tightness, even under heavy rain.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be further elucidated on the basis of exemplary embodiments shown in the accompanying drawings.

Here means:

Giant. 1 shows a three-dimensional configuration of a door sill according to the invention;

Giant. 2 is a cross-sectional view of the door sill and door leaf of FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to a door sill arrangement with a sill body and sealing means located on the door leaf and door frame.

1 and 2 show a three-part door sill arrangement. As is apparent from FIG. 1, the door sill arrangement consists essentially of two, for example aluminum-shaped profile sections I and 2, of which profile section I is located on the inside of the door separating the interior and exterior spaces, while profile section 2 is located. on the outside of the door. A connecting profile 3 made of a thermally non-conductive material, for example plastic, is inserted between the two profile parts 1 and 2. Above the connecting profile 3 there is also a sealing strip 4 with a sealing lip 4a. This sealing lip acts together with the sealing lip 5a formed on the sealing strip 5 located on the underside of the door leaf 6. The door sill is slightly inclined from the sealing lip 4a to the outside of the door. The two door sill sections 1 and 2 are thus thermally separated.

On the right and left side of the door leaf 6 is further provided a corner seal 7 with a sealing lip 7a, which extends on both sides to the sealing strip 5. The corner seal 7 with a sealing lip 7a acts together with a seal 8 provided with a sealing profile 8a provided on the door frame 9.

Further details of the door sill arrangement are shown in Fig. 2, which shows that the connecting profile 3 thermally separates the two profile parts I and 2, with good thermal insulation and water tightness properties achieved by the joint action of the sealing tape 4 with the sealing lip. 4a, located above the connecting profile 3, with a sealing lip 5a formed on the sealing strip 5 provided on the door leaf 6,

The door sill arrangement thus formed satisfactorily prevents the ingress of water due to heavy rain inside the building and also exhibits good thermal and sound insulation effects.
