Description

The present invention relates to a door leaf according to the preamble of claim 1, a door with such a door leaf according to claim 19 and a method for producing such a door leaf according to claim 20.

Doors with a door leaf, made of a sandwich plate, that is to say a plate with two fixed shells between which an insulating material is located, are known from the prior art, e.g. known as house doors for low energy houses.

Usually, a closing profile or wing profile must be attached to the sandwich panel of the door leaf at the edges so that the sandwich panel becomes a functionally usable door panel. By the wing profiles, e.g. created a way to attach seals, locking devices or door hinges on the door, so that in conjunction with a corresponding frame of window frame profiles a door with desired functions is formed.

According to the prior art, the attachment of such closure or wing profiles on the sandwich panel of the door leaf is often realized by a cohesive adhesive bond.

So will in the EP 1 568 842 A2 describe a door leaf, a door provided therewith and a manufacturing method therefor. The door leaf has a profile designed as a hollow profile airfoil extruded light metal, in particular an aluminum alloy, which is adhesively bonded by adhesive, such as a PU adhesive with a sandwich panel of the door leaf.

As a disadvantage of the solution according to the EP 1 568 842 A2 the curing time of the adhesive has an effect as it prevents the joined door from being installed immediately after the joining process has taken place. Furthermore, the quite massive wing profile gives a negative visual impression of such a door leaf.

In the DE 203 14 017 U1 For example, a filling plate is described which comprises a core of a thermally insulating material and two outer cover layers of lesser thickness than the core. This core and the cover layers form a sandwich panel, which is firmly inserted into a frame of hollow profiles.

According to the technical teaching of DE 203 14 017 U1 It is envisaged that the wing profiles each have two profiles which are interconnected by two insulating webs made of plastic. As a result, the wing profiles are complex in their design and therefore expensive. Another disadvantage is the proposed joining method between wing profiles and filling plate by gluing, since the adhesive must first harden and thus the door can not be installed immediately after the successful joining process.

In order to avoid the curing times of the adhesive, through which such a joined door leaf also causes considerable costs, other joining methods have been developed for joining sash profiles and sandwich panels.

In the DE 20 2014 101 376 U1 a window or door leaf is presented with a holding device for receiving a wing-covering surface element. According to this solution, it is provided that the surface element, which is constructed according to the principle of a sandwich plate, has a holding element to which the respective wing profiles are fastened by screws to the surface element.

A disadvantage of the solution after the DE 20 2014 101 376 U1 is the required provision of the surface element with the holding element. Due to the additional holding element, the surface element is expensive and its production consuming and thus costly.

an enlarged detail of the embodiment of the Fig. 12 ,

In the Fig. 1 is a partial section of the locking side of a door 1 with a door 2 and a window frame 3 shown. The frame 3 is assembled from sections of a frame profile 4. The door 2 has a sash 5, which is assembled from sections of a sash profile 6. The sash profile 6 is preferably designed as a composite profile.

The door 2 also has a filling 7, which is enclosed by the sash 5. The filling 7 is formed as a sandwich panel or plate, which identifies an inner shell / plate 8a and an outer shell / plate 8b, each preferably made of a solid material, more preferably of a metallic material or plastic or of a plastic / metal Composite are made.

The filling 7 also comprises a lying between the inner shell 8a and the outer shell 8b, heat-insulating core 9, which is designed as a plate, and which is preferably made of a plastic material, for example a polymer foam.

The filling 7 is referred to in the context of the present invention as the first insulating layer.

However, the filling 7 may also be made in one piece only from a thermally insulating material, e.g. a material plate, be formed. In this case, the filling 7 may be, for example, a dimensionally stable plastic plate made of a heat-insulating plastic material, which forms sufficient resistance for anchoring a screw or a rivet.

Furthermore, alternatively, only an inner shell 8a or an outer shell 8b with the heat-insulating material form the filling. The filling may be formed integrally as a composite material.

With an outer shell and an inner shell, this heat-insulating material forms the core 9.

The filling 7 here also has an optional compensating layer 10, which is arranged between the outer shell 8a and the core 9. Overall, the filling 7 thus forms a multilayer plate in this preferred variant.

The material of the compensating layer 10 is preferably designed to be more elastic than the material of the outer and / or inner shell and particularly preferably designed to be more elastic than the material of the core 9. It serves for dilatation compensation.

For example, the terms "inside" and "outside" refer to an interior of a building that the door 1 separates from the environment or an outdoor area. Here, the inner shell 8a is the shell of the filling 7, which in the direction of positive x-coordinates with respect to the coordinate system in Fig. 1 is arranged. Accordingly, the outer shell 8b is the shell of the filling 7, which in the direction of negative x-coordinates with respect to the coordinate system in Fig. 1 is arranged.

The compensating layer 10 is an optional component of the filling 7 and is used when due to temperature differences on both sides of the door leaf 2 with greatly different thermal expansions of the two shells 8a, 8b is to be expected. Due to its properties, the compensation layer 10 compensates for the thermal expansion of the outer shell 8b on the outside of the door leaf 2. For a detailed description of the properties and the function of the compensation layer 10, reference is made to FIGS DE 203 14 017 U1 directed. This compensating layer 10 serves for dilatation compensation.

The frame profile 4 has a first metallic outer profile 11, in which here at least one hollow chamber is formed, and a metallic center profile 12, in which also preferably at least one hollow chamber is formed. The first metallic outer profile 11 is connected to the metallic center profile 12 via at least one or more first insulating webs 13, 14. These insulating webs 13, 14 between the first metallic outer profile 11 and the metallic center profile 12 form a first insulating land zone I or plane. The first metallic outer profile 11 also has, outside the first insulating land zone I, a web which has a groove 15 at its free end.

The metallic center profile 12 has in each case on its sides, each in the y-direction (see coordinate system in Fig. 1 ) are aligned, in each case a groove 16a, 16b with an undercut on. In the groove 16b, whose opening in the direction of negative y-coordinates with respect to the coordinate system in Fig. 1 is directed, a cover strip 25 is clipped.

The metallic center profile 12 is connected to a second metallic outer profile 17, in which preferably at least one hollow chamber is formed, via at least one or more second insulating webs (aligned parallel here) 18, 19 connected. These insulating webs 18, 19 between the metallic center profile 12 and the second metallic outer profile 17 form a second insulating land zone II or plane.

The insulating webs 13, 14, 18, 19 here-exemplarily- no hollow chambers. Alternatively, the insulating webs 13, 14, 18, 19 but also one or more Have hollow chambers or the insulating webs 13, 14, 18, 19 may be summarized by transverse webs to a kind of superior insulating profile.

The insulating webs 13, 14, 18, 19 are here -rein exemplary arranged in a plane. Alternatively, it is also possible that the insulating webs 13, 14, 18, 19 are each offset horizontally from each other or vertically offset from one another. Likewise, a diagonal orientation of the insulating webs 13, 14, 18, 19 is possible.

The first insulating land zone I, which is formed between the first metallic outer profile 11 and the metallic center profile 12 by the insulating webs 13, 14, has a hollow chamber. The second insulating land zone II, which is formed between the metallic center profile 12 and the second metallic outer profile 17 by the insulating webs 18, 19, also has a hollow chamber.

Preferably, the insulating webs 13, 14, 18, 19 are web-shaped in cross-section.

The insulating webs 13, 14 of the first insulating land zone I and the insulating webs 18, 19 of the second insulating land zone II have here in each case two thickened end sections. The respective end portion preferably has a trapezoidal or triangular or wedge-shaped or L-shaped or rectangular cross-section. The respective groove accordingly has a cross section with a corresponding cross section.

Preferably, each of the end sections engages in a corresponding groove. The respective groove is limited on its one, the respective hollow chamber, the respective metal profile 11, 12, 17 side facing each by an anvil-shaped projection 20 which is made together with the respective metal profile 11, 12, 17 by a forming process, such as extrusion , The groove is bounded on its other, the respective hollow chamber of the respective metal profile 11, 12 side facing away in each case by a web 21 with a free end. The fin 21 with a free end is placed by a forming process on the respective end portion, whereby the respective end portion of the insulating webs 13, 14, 18, 19 in the x and y directions with respect to the coordinate system in Fig. 1 is fixed positively.

In each case the insulating web 14, 19 in the direction of negative y-coordinates with respect to the coordinate system in Fig. 1 the first insulating land zone I and the second insulating land zone II has a groove 22 with an undercut, wherein the groove 22 is designed here as a groove with T-shaped cross-section.

In the groove 22 of the insulating web 14 of the first insulating land zone I, a sealing profile 23 is positioned and fixed, which has a foot 22 integrally formed with the groove 22, integrally formed on the sealing profile, which engages in the groove 22 and snapped into the groove 22 is. The geometric design of the undercut of the groove 22 may also be performed differently than T-shaped.

In the groove 22 of the insulating web 19 of the first insulating land zone II, a cover strip 24 is positioned and fixed, which has a foot 22 integrally formed with the groove 22, integrally formed on the cover strip, which engages in the groove 22 and snapped into the groove 22 is. The geometric design of the undercut of the groove 22 may also be performed differently than T-shaped.

The metallic outer profiles 11, 12 and the metallic center profile 17 are preferably made as extruded aluminum profiles. Alternatively, the production is also possible from a different material such as steel and / or another manufacturing method. The insulating webs 13, 14, 18, 19 are made of a plastic material, such as e.g. Polyamides (PA66, PA6, PPA), polyester (PET, PBT), polyolefins (PP) or polyvinyl chloride (PVC) produced, so that in each case a substantial thermal separation between the metal profiles 11, 12, 17 is achieved.

The sash profile 6 has a substantially rectangular cross section (see also Fig. 6 ). The one leg of the sash profile 6 is essentially formed by a metallic profile 26, which engages in a first partial recess 27 of the filling 7. The first partial recess 27 comprises the inner shell 8a and a part of the core 9 of the filling 7. In the metallic profile 26 at least one hollow chamber is formed, in which case the metallic profile 26 is formed by way of example with two hollow chambers. The metallic profile 26 also has a positive direction on its side which is arranged in the direction of positive x-coordinates Y coordinates aligned web, which forms a groove 28 into which a sealing profile 29 is inserted.

The metallic profile 26 has, on its side arranged in the direction of positive x-coordinates, a single fastening web 30 which is oriented in the direction of negative y-coordinates and forms a groove 31 at its free end. The groove has a cross-section with an undercut. The attachment web 30 rests on the inner shell 8a and overlaps it on a portion of the inner shell 8a.

The metallic profile 26 is arranged on the inside of the door leaf 2. Due to the fact that the metallic profile 26 engages in the first partial recess 27 of the filling 7, it is in the direction of the positive x-direction with respect to the coordinate system in FIG Fig. 1 narrow trained. This results in an advantageously appealing visual impression of the metallic profile 26 of the sash frame profile 6 and thus of the sash frame 5 on the inside of the door leaf.

The sash profile 6 also has an insulating web 32. The insulating web 32 forms the other leg of the substantially rectangular sash frame profile 6 and is thus arranged at right angles to the shells 8 a, 8 b of the filling 7 of the door leaf 2. The insulating web 32 engages in a second partial recess 33 of the filling 7. The second partial recess 33 comprises the core 9 of the filling 7 and the optional compensation layer 10 present here. The second partial recess 33 is moved in the direction of negative x-coordinates with respect to the coordinate system in FIG Fig. 1 bounded by the outer shell 8b of the filling 7. The second partial recess 33 and the first partial recess 27 form an overall recess 27, 33, engage in the essential parts of the sash profile 6. Due to the insulating web 32, a heat bridge formation between the outer shell 8b and the inner shell 8a of the filling 7 of the door leaf 2 is advantageously effectively prevented, so that the thermal insulation properties of the door leaf 2 are not impaired by the casement profile 6.

The metallic profile 26 of the sash profile 6 has on its side facing away from the fastening web 30 a with respect to the coordinate system in Fig. 1 in the negative x-direction opening groove 34 with an undercut on. The insulating web 32 engages with a geometrically corresponding end portion in the groove 34 a.

The groove will move in the direction of negative y-coordinates with respect to the coordinate system Fig. 1 delimited, inter alia, by a web 35, which is preferably converted to a wall of the groove 34 by a forming process, and thereby the end portion of the insulating web 32 in the x and y directions with respect to the coordinate system in Fig. 1 is determined in the groove 34.

The web 35 is advantageously arranged in one piece on the metallic profile 26 of the sash profile 6 so that it is easily accessible for the forming process. Aligned by its position to the core 9 of the filling 7, it is virtually in relation to the sash profile 6 on the inside of the sash profile 6 and is there in the installed state of the sash profile 6 for a user of the door 1 advantageously not visible.

The insulating web 32 has here two hollow chambers. Alternatively, the insulating web 32 may also have less than two or more than two hollow chambers. The insulating web 32 has an opening 36 which opens into one of the two hollow chambers. As a result, a groove is virtually formed with an undercut. In the groove engages a geometrically corresponding foot of a seal bearing 37 a. The seal bearing 37 is disposed terminally on the outer shell 8b and is preferably arranged as a projection perpendicular to a plane of the plate-shaped outer shell 8b, such that the seal bearing 37 is disposed above the core 9 of the filling 7 and the foot of the seal bearing 37 in the direction of the core 9 from the seal bearing 37 protrudes.

The metallic profile 26 is preferably made as an extruded aluminum profile. Alternatively, the production is also possible from a different material such as steel and / or another manufacturing method. The insulating ridge 32 is made of a plastic material, such as plastic. Polyamides (PA66, PA6, PPA), polyester (PET, PBT), polyolefins (PP) or polyvinyl chloride (PVC) produced, so that each one reaches a substantial thermal separation between the metal section 26 and the shell 8b of the filling 7 of the door leaf 2 becomes.
