Description

The present invention relates to a door, in particular a front door, wherein the door has a door frame formed from a plurality of profile sections, wherein at least one of the profile sections has a main hollow chamber with a frame reinforcement element received therein; a door leaf which comprises a leaf frame formed from a plurality of profile sections and a filling element received in the leaf frame; and at least two door hinge elements by means of which the door leaf is pivotably mounted in the door frame, wherein each door hinge element comprises a leaf hinge connected to the door leaf and a frame hinge connected to the door frame, wherein the leaf hinge is each fastened to the door leaf with at least one frame hinge fastening means and the frame hinge is each fastened to the door frame with at least one frame hinge fastening means, wherein the at least one frame hinge fastening means is guided through at least one profile wall of the door frame. In addition, the present invention relates to a reinforcement element for such a door.

Such doors and suitable frame reinforcement elements are widely known in the art. For example, DE 201 02 813 U1 a door of this type in which a door hinge fastening means is guided through at least one profile wall of the door frame and one leg of the frame reinforcing element. The frame reinforcing element is only designed as a single wall on its side facing the door hinge elements. A disadvantage of the DE 201 02 813 U1 The door described above shows that, particularly under high mechanical and thermal stress, an unwanted twisting of the door leaf can occur, which prevents the closing of the DE 201 02 813 U1 door is made more difficult or even completely prevented.

Against this background, the object of the present invention is to provide a door that at least partially overcomes the disadvantages of the prior art. In particular, the door according to the invention should be able to withstand higher mechanical and thermal loads. In addition, the present invention is to provide a reinforcing element for such a door.

According to the present invention, these and other objects are achieved by a door having the features of claim 1 or by a reinforcing element having the features of claim 9. Preferred embodiments of the door according to the invention and of the reinforcing element according to the invention are described in the respective dependent claims.

The present invention is based on the finding that the transfer of the load of the door leaf via the frame hinge elements into the door frame only takes place at the position at which the respective frame hinge fastening means penetrates the frame reinforcement element. The resulting torque can result in the door leaf twisting as an unwanted consequence. The formation of such a torque can be counteracted by the load transfer for each frame hinge element into the door frame taking place at several positions. According to the invention, this is achieved by the frame hinge fastening means penetrating the frame reinforcement element in several positions for load transfer. In order to further reduce the torque generated by the load of the door leaf, the positions in which the respective frame hinge fastening means penetrates the frame reinforcement element are spaced apart from one another. In order to reduce the risk of deformation of the frame reinforcement element, the present invention provides that these positions are introduced into two sections of the frame reinforcement element that are spaced apart from one another and run essentially parallel to one another. These sections are located in the main hollow chamber of the door frame on the side facing the door hinge elements.

Accordingly, the present invention lies in the provision of a door, in particular a front door, wherein the door has a door frame formed from a plurality of profile sections, wherein at least one of the profile sections has a main hollow chamber with a frame reinforcing element received therein; a door leaf which comprises a leaf frame formed from a plurality of profile sections and a filling element received in the leaf frame; and at least two door hinge elements by means of which the door leaf is pivotably mounted in the door frame, wherein each door hinge element comprises a leaf hinge connected to the door leaf and a frame hinge connected to the door frame, wherein the leaf hinge is each fastened to the door leaf with at least one door hinge fastening means and the frame hinge is each fastened to the door frame with at least one frame hinge fastening means, wherein the at least one frame hinge fastening means is guided through at least one profile wall of the door frame, wherein the door is characterized according to the invention in that the frame reinforcing element has at least two substantially parallel to one another on its side facing the door hinge elements. has mutually spaced-apart sections through which the at least one frame band fastening element is guided. Furthermore, the present invention lies in the provision of a frame reinforcement element for such a door.

With regard to the door according to the invention, it is preferred if the distance between the sections of the frame reinforcement element that run essentially parallel to one another is in the range from 3 mm to 3.0 cm. A distance in this range allows the frame reinforcement element to be kept sufficiently compact for inclusion in the main hollow chamber of the corresponding frame profile section, while the distance ensures sufficient load transfer so that the smooth running of the door according to the invention is guaranteed even under high mechanical and/or thermal loads. In this context, it is particularly preferred if the distance between the sections of the frame reinforcement element that run essentially parallel to one another is in the range from 5 mm to 2.0 cm.

Additionally or alternatively, it can be helpful if the sections that run essentially parallel to one another are arranged in a region of the frame reinforcement element that has a height that is reduced compared to the maximum reinforcement element height. This also contributes to the torque generated by the load of the door leaf being able to be better transmitted to the door frame. For this purpose, it can be helpful if the main hollow chamber of the profile section of the door frame has a region that has a chamber height that is reduced compared to the maximum height of the main hollow chamber. In particularly preferred embodiments of the door according to the invention, the sections of the frame reinforcement element that run essentially parallel to one another are arranged at least partially in the region of the main hollow chamber with a reduced chamber height.

It can also prove useful if the section of the sections running essentially parallel to one another that is directed towards the inside of the profile of the frame reinforcement element comprises a deflection section whose section to an outer section is at least partially less than 4 mm, in particular less than 2 mm. Such a deflection section ensures that the frame band according to the invention minus the reinforcement element wedges itself against the door frame when the frame band fastening element is tightened.

Preferably, the profiles for both the door leaf frame and the door frame are each a hollow chamber profile comprising several hollow chambers, in particular a plastic hollow profile chamber profile comprising several hollow chambers or an aluminum hollow chamber profile comprising several hollow chambers, with plastic hollow profile chamber profiles being particularly preferred in each case. The design of the door according to the invention as a plastic door is therefore particularly preferred.

The features and their effects described with respect to the door according to the invention apply accordingly with respect to the reinforcing element according to the invention.

The door according to the invention, the frame reinforcement element according to the invention and individual parts thereof can also be manufactured line by line or layer by layer using a line-building or layer-building manufacturing process (e.g. 3D printing). However, the profiles of the door frame and the door leaf are preferably manufactured by extrusion or extrusion and cut to length to form beams that are mitred and welded or connected to one another. The respective reinforcement elements are preferably manufactured from corresponding sheets by roll forming processes known per se.

In the following, the invention will be explained in detail with reference to the embodiment shown in the figures. The present invention is explained using a plastic door with a plastic hollow profile frame. However, it is understood that the present invention can also be applied to other doors with hollow profiles, for example aluminum hollow profiles. The embodiment shown in the figures is, however, only to be understood as an example and is not intended to have a restrictive effect.

In 1 the basic structure of a door 1 according to an embodiment of the present invention is shown in a schematic representation. The door 1 according to the invention is designed as a plastic door. In the 1 In the embodiment shown, the door 1 according to the invention comprises a door frame 2 and a door leaf 4 which is rotatably attached to the door frame 2 via three door hinge elements 31, 32, 33. The door frame 2 is constructed from three profile sections 21, 22, 23 of a plastic profile which are welded together in the corner area and a threshold 5 which is connected to the two adjacent plastic profile beams 21, 23 via threshold holders.

The door leaf 4 comprises a leaf frame 6 made of four plastic profile beams 61, 62, 63, 64 welded together in the corner area, which in the embodiment shown have an identical cross-section, as well as a filling element 7 accommodated in the leaf frame 6, in particular a door filling or glazing. A lock case (not shown) is accommodated in the plastic profile beam 63, which in 1 can be identified by a keyhole 8 and can be operated with a door handle 9. In 2 is a section of the hinge side edge area of the 1 The door 1 according to the invention shown in cross section is shown. The cutout is around the 1 The profile section 61 has an outer overlap 611 which, together with the upper web 612 and a retaining strip 613 locked into a retaining strip groove, forms a fold which, in the embodiment shown, has a substantially U-shaped cross section. The filling element 7, for example a double glazing or a plastic insert, is received in the fold so that the sash frame 6 runs around the filling element 7 on the front side.

The profile section 61 of the sash frame 6 is made up of several hollow chambers which are surrounded by webs of the profile section 61. A sash reinforcement element 614 is accommodated in a main hollow chamber of the profile section 61, which is also referred to as a reinforcement chamber, which serves to improve the mechanical stability of the sash frame 6.

In a similar way, the profile section 21 of the door frame 2 is constructed as a section of a hollow chamber profile made up of several hollow chambers, which are surrounded by webs of the profile section 21. A frame reinforcing element 10 is accommodated in the main hollow chamber 211 of the profile of the door frame 2. This frame reinforcing element 10 is in 3 shown in an enlarged cross-sectional view. In the 3 In the embodiment shown, the frame reinforcement element 10 is designed as a steel reinforcement and has a key-like cross-section. The frame reinforcement element 10 has an area 101 with a higher profile height, which corresponds to the handle of the key, and an area 102 with a lower profile height, which corresponds to the bit of the key. The area 101 with the higher profile height has a substantially rectangular cross-section, in which the corners are rounded and one side is essentially open. The area 102 with a lower profile height is integrally formed on the area 101 and is designed as a web, which is deflected several times on its side facing away from the area 102. Due to this deflection, the frame reinforcement element 10 has two sections 103, 104 in the area 102, which run essentially parallel to one another and in the 3 In the embodiment shown, they have a distance of approximately 8 mm from each other.

The section 103 of the two sections 103, 104, which are essentially parallel to one another and which is directed towards the profile interior of the frame reinforcement element 10, comprises a deflection section 105. This deflection section 105 is only a small distance from an outer section 106. In the 2 and 3 In the embodiment shown, this distance is approximately 1.5 mm.

The main hollow chamber 211 of the frame reinforcing element 10 has a flatter section to match the area 102 with a lower profile height. The frame reinforcing element 10 is then inserted into the main hollow chamber 211 of the frame reinforcing element 10 such that the area 102 with a lower profile height is located in this flatter section. As a result, the two essentially parallel 103, 104 of the frame reinforcing element 10 face the door hinge element 31.

The door hinge element 31 is made up of a leaf hinge 311 and a frame hinge 312, which are connected to one another via a door hinge roller 313. For fastening to the door leaf 4, the leaf hinge 311 is fastened to the leaf frame 6 by a leaf hinge fastening means 314, which in the embodiment shown is designed as a fastening screw. The leaf hinge fastening means 314 penetrates a migration of the profile section 61 and a wall thickness of the leaf reinforcement element 614. The frame hinge 312 is fastened to the door frame 2 by a. The frame band fastening means 315 penetrates several profile walls of the profile section 21 of the door frame 2. In addition, the frame band fastening means 315 also penetrates the two sections 103, 104 of the frame reinforcing element 10, which run essentially parallel to one another and are spaced apart from one another. This transfers the load of the door leaf gels 2 via the frame band elements 312 in the door frame 2, in particular in the frame reinforcement element 10 of the door frame 2, in two separate positions, namely in those in which the frame band fastening means 315, the sections 103, 104. In this way, the torque generated by the load of the door leaf 2 can be absorbed in the frame reinforcement element 10 of the door frame 2. This significantly reduces the risk of unwanted twisting of the door leaf 2 even under high mechanical and/or thermal loads.

It can also prove useful if the section of the sections running essentially parallel to one another directed towards the profile interior of the frame reinforcement element comprises a deflection section whose section to an outer section is at least partially less than 4 mm, in particular less than 2 mm. Such a deflection section ensures that when the frame band fastening element 315 is tightened, the deflection section 105 is pressed against the outer section 106 of the frame band reinforcement element 10. As a result, the frame band reinforcement element 10 is wedged against the profile section 21 of the door frame 2, which provides additional stability in the door frame 2.

The invention was previously explained in detail with reference to the embodiment of the door according to the invention shown in the figures. Sections of plastic hollow profiles are described as profile sections for the door frame and the door leaf. The statements also apply accordingly to other types of hollow profile frames, for example aluminum profiles, aluminum-plastic composite profiles, aluminum-wood composite profiles, wood-plastic composite profiles and the like. It is therefore understood that the present invention is not limited to this embodiment, but that the scope of the present invention arises from the claims.
