Description

The invention relates to a device for supporting and securing window or door frames on a delimitation of a wall opening in a wall with the features of the preamble of claim 1.

Such a device is from EP 2 514 899 A2 known. Specifically, a fastening device is described on a masonry, which consists of a profile rail and a support bracket adjustably attached to this. The profile rail is fastened to a horizontal wall section of the wall opening by means of fastening openings. An elongated hole in the profile rail is used for horizontally adjustable fastening of the support bracket.

Furthermore, the EP 1 500 767 A2 discloses a device for supporting and securing window or door frames to a boundary of a wall opening in a wall. The device disclosed there has an angular profile with a horizontal and a vertical leg. The device is attached to the inside of the wall with the vertical leg. The horizontal leg of the device is pushed into a U-shaped profile rail. At the end of the profile rail there is a vertically adjustable adjustment element. The adjusting element is designed as a threaded bolt which is passed through a tubular guide of the profile rail and is supported vertically on a nut. A profile piece connected to the adjusting element serves to support a window or door frame.

After all, that is EP 2 599 944 A1 a window frame support can be found, which is also used for a front attachment of a window frame to a window reveal of a wall. The window frame support has a cantilever strut which can be attached to the window reveal in a cantilevered manner. Furthermore, there is an inclined support which can be fixed on an outside of the wall and which supports the cantilevered cantilever strut obliquely on the wall. In addition, there is a distance adjustment device for the inclined support that runs perpendicular to the cantilever strut and with which a distance between an end of the inclined support facing the wall and the cantilever strut can be adjusted.

The devices mentioned here have in common that they have a complicated structure, which makes it difficult to handle them during assembly and increases the risk of assembly errors.

The present invention is therefore based on the object of providing a device for supporting and securing window or door frames on a delimitation of a wall opening in a wall, which device is easy to handle.

The present object is achieved by a device with the features of patent claim 1. Advantageous designs or developments of the invention can be found in the dependent claims.

The present invention is therefore based on a device for supporting and securing window or door frames to a boundary of a wall opening in a wall. The device has at least one horizontal leg, which in a mounting position of the device runs horizontally along the wall or the wall opening. A support bracket of the device has at least one contact surface with which the support bracket rests on the wall. The support bracket thus serves to support the forces on the wall on the horizontal leg.

The invention now proposes that the support bracket is designed as a molded part on the horizontal leg.

A device for supporting and fastening window or door frames to a delimitation of a wall opening in a wall is thus provided, which device is extremely simple. The risk of assembly errors is thereby reduced to a minimum and the assembly of the device and the subsequent assembly of a window or door frame can be carried out extremely quickly. Due to the one-piece design, i.e. the material connection between the horizontal leg and the support bracket, a high level of stability can also be achieved in all areas of the device.

In a further development of the invention, it is proposed that the projection has the shape of a right-angled triangle in outline, with an edge region which adjoins the horizontal limb and an edge region which protrudes from the horizontal limb. The edge areas enclose a right angle with one another. Furthermore, there is an edge area which forms a hypotenuse and which connects the two other edge areas to one another. The contact surface is arranged in the area of a lower end of the edge area protruding from the horizontal leg.

In this way, the prerequisite is created for a very good transmission of a weight acting on the support surface to the wall.

But it is also conceivable that the contour has a different shape, for example a square shape or the shape of a section of a circle.

It is useful if the contact surface protrudes from the edge area. In other words, the contact surface is somewhat offset from the edge area in the direction of the longitudinal extension of the horizontal leg. In this way, a defined introduction of force into the wall can be promoted.

According to a very advantageous embodiment of the concept of the invention, it is proposed that the surface extension of the contact surface is several times greater than a thickness of the projection. The molding is plate-like and only has a small thickness of a few millimeters, preferably about 3 mm to 6 mm.

Such an enlargement of the contact surface allows the compressive force to be better distributed over the subsurface formed by the wall. This prevents a strong, local load on the subsurface and prevents damage to the wall or the brick. In the worst case, damage to the brick can lead to the brick breaking. The aforementioned training therefore also has a positive effect on the longevity of the construction. The longevity of the construction is particularly influenced by the “working” of the device on the masonry or thermal effects (expansion / shrinkage).

It is conceivable, for example, that the contact surface is designed to be rectangular in outline. Such a shape is easy to manufacture and promotes good transmission of the force. However, other contours of the contact surface are also conceivable, for example round or oval.

According to another development, the projection has a cylindrical thickening running parallel to the edge region (which protrudes from the horizontal limb). The cylindrical thickening runs through the entire molding, a through-hole being made in the molding. The drilling provides the prerequisite for an easily manageable height adjustment of a window or door frame to be supported. For example, it is conceivable to insert a height-adjustable threaded rod or screw into the bore. Since the bore runs through the entire projection and is therefore comparatively long, a significantly better guidance of a threaded rod or screw used for height adjustment can be achieved, whereby possible tilting can be minimized.

Alternatively, according to another development, it is also conceivable that the through hole is designed as a threaded hole. This provides the prerequisite that the height adjustment can take place directly by turning the threaded rod or screw. A height adjustment of a supported window or door frame is then possible even when the threaded rod or screw is loaded, without having to lift the window or door frame.

According to a very advantageous embodiment of the inventive concept, the molding is arranged on a free end of the horizontal leg. This is done in such a way that the edge area forming the hypotenuse extends obliquely downward from the free end of the horizontal leg. In other words, the horizontal leg is supported on the wall precisely in the area where the horizontal leg protrudes over the wall. As a result, kinking of the horizontal leg can be effectively prevented.

In a further embodiment of the invention, it is proposed that the horizontal leg have a flat cross section, with a thickness that continuously decreases in the direction of the lateral edges of the cross section. The thickness of the cross-section is therefore maximal in the middle of the cross-section and then decreases continuously towards the two edge regions of the cross-section.

Such a shape promotes inexpensive and easy producibility of the device.

In another embodiment of the inventive concept, it is proposed that a second vertical limb protruding from the horizontal limb is molded onto the horizontal limb (the horizontal limb and the vertical limb thereby preferably form an angle profile with a 90 ° angle or an approximately 90 ° angle) . The formation protrudes from the horizontal limb in the same direction as the vertical limb and has at least one contact surface running parallel to the vertical limb. Furthermore, there is a clear distance between the contact surface and the vertical limb and is dimensioned in such a way that a commercially available brick for erecting the wall can be received between the contact surface and the vertical limb.

This development results in increased flexibility in the assembly of the device.

A particularly inexpensive production of the device is possible if it is produced by a casting process or by an additive manufacturing process.

For example, sand casting, permanent mold casting or die casting can be used as manufacturing processes. However, it is also entirely conceivable to manufacture the device from a powdered starting material by sintering with a laser. Such a process (also called 3D printing) can be used to produce any three-dimensional geometries, even with undercuts.

The preferred materials for the device are aluminum, steel, cast iron, zinc and copper alloys (bronze, gunmetal, brass).

Preferred exemplary embodiments of the invention are shown in the figures and are explained in more detail in the following description with reference to the figures. This also makes further advantages of the invention clear. The same reference symbols, even in different figures, relate to the same, comparable or functionally identical components. Corresponding or comparable properties and advantages are achieved, even if a repeated description or reference is not made. The figures are not, or at least not always, to scale. In some figures, proportions or distances can be exaggerated in order to be able to emphasize features of an exemplary embodiment more clearly.

First of all, the 1 Referenced. In this figure is a device according to the invention 1 shown for supporting and securing window or door frames. The device 1 is formed by an angle profile, with one in the assembly position of the device 1 (compare also 5 ) vertically extending vertical legs 10 and a second horizontal leg running horizontally in such an assembly position 20th .

The vertical leg 10 and the horizontal leg 20th take an angle together α of 90 degrees or about 90 degrees.

The horizontal leg 20th has on its underside, which is in the assembly position, on the side of the vertical leg 10 , a downwardly protruding, roughly triangular shape in outline 30th on. The molding 30th so stands in the same direction from the horizontal leg 20th off like the vertical leg 10 .

The shape of a right triangle of the molding 30th is through a first, horizontally running edge area in the assembly position 31 and a second edge region that runs vertically in the assembly position 32 the molding 30th educated. The edge areas 31 , 32 close a right angle β or at about such an angle with each other.

The ends of the border areas 31 and 32 are through a border area 33 connected to each other, through which a hypotenuse of the formation 30th is trained.

It can also be seen from the figure that the device 1 or the thighs 10 and 20th one in the longitudinal direction of the legs 10 , 20th extending central area M. exhibit. The molding 30th is in the mid-range M. on the horizontal leg 20th molded. This is done in such a way that the mentioned edge area 33 from a free end 21 of the horizontal leg 20th goes obliquely downwards.

Furthermore, the formation 30th a cylindrical thickening 34 on. The cylindrical thickening 34 is with its longitudinal extent parallel to the longitudinal extent of the vertical leg 10 or parallel to the longitudinal extent of the edge area 32 aligned. In the cylindrical thickening 34 is a through hole 35 brought in. It can be seen that the cylindrical thickening 34 in their length including the through hole 35 at this point over the entire molding 30th extends. The molding 30th is plate-like and preferably only about 3 mm to 5 mm thick.

Notwithstanding the exemplary embodiment, it is conceivable that in the formation 30th between the edge areas 31 to 33 one or more recesses are made. In this way, cost and weight savings can be achieved without any significant loss of stability.

In the area of a pointed end of the molding 30th , so where the edge areas 32 and 33 converge is yet another, plate-like projection 40 available. The plate-like molding 40 is rectangular in outline. In a departure from the exemplary embodiment, it is conceivable that the plate-like projection 40 also has other outlines, for example a round or oval outline.

The plate-like molding 40 points on her the vertical leg 10 facing side a contact surface 41 on, which is accordingly also rectangular. The contact surface 41 points out of the formation 30th facing inside of the vertical leg 10 a clear distance a. The clear distance a is dimensioned such that in the assembly position of the device 1 a commercially available brick due to the distance a S. can be included (compare also 5 ).

For fastening the device 1 in the area of the vertical leg 10 and / or the horizontal leg 20th are used for fastening openings 50 . The mounting holes 50 can be circular. In a departure from the exemplary embodiment, the device can also have more or fewer fastening openings 50 exhibit. It is also conceivable that the fastening openings 50 or part of the fastening openings 50 are designed as elongated holes.

Based on 2 it should be made clear that the device 1 , so both the vertical leg 10 as well as the horizontal leg 20th are flat and have a thickness d exhibit. The fat d is preferably only about 3 mm to 6 mm. The fat d is in the middle range already mentioned M. maximum and takes to edges 22nd continuously from. This creates an angle γ to an imaginary horizontal in the figure.

Such a shape makes the device suitable 1 particularly good for production in a casting process and can therefore be produced very easily and inexpensively.

Based on 3 is now the device 1 visible in their mounting position. Here it is on a standard brick S. in the area of an opening Ö one through several bricks S. formed wall W. hung up. It can also be seen that the device 1 in the area of the fastening openings 50 was attached by unspecified fasteners.

The commercially available brick S. can for example be a commercially available perforated brick, a commercially available aerated concrete block, a commercially available sand-lime brick and the like. An adaptation of the device 1 Different, commercially available stone sizes can be achieved through different versions of the device according to the invention 1 , so primarily through a correspondingly adapted length of the horizontal leg 20th and thus the clear distance a.

In the 3 is the assembled device 1 from an outside of the wall W. can be seen from while the device 1 in the 4th from an inside of the wall W. is shown from.

From the 5 it is particularly clear that the device 1 in their mounting position so on the brick S. rests that they this with the clear distance a between the contact surface 41 and the inside of the vertical leg 10 can accommodate.

In particular, the contact surface are in the assembly position 41 and the inside of the vertical leg 10 on the brick S. at.

There is also an insulation area in this figure D. can be seen, which is indicated by an insulation material indicated by dashed lines 80 is formed. The insulation area D. is located in front of the through the bricks S. formed wall W. .

It can be seen that the length of the horizontal leg 20th the device 1 is chosen in such a way that one of the brick S. or from the wall W. cantilevered part 23 results (compare 3 ).

Exactly under this protruding part 23 is also the molding already described 30th arranged. This can result in kinking of the horizontal leg 20th can be effectively prevented in this area even under heavy loads.

It is also clear from the figure that the contact surface 41 in the direction of the vertical leg 10 from the edge area 32 is separated, so from the edge area 32 in the direction of the vertical leg 10 protrudes. This is on the underside of the horizontal leg 20th a gap Z between the edge area 32 and the wall W. educated. In this way there is a well-defined transmission of force from on the cantilevered part 23 (see. 3 ) weight forces on the contact surface 41 into the wall W. favored.

Through the top of the horizontal leg 20th in the area of the cantilevered part 23 (see. 3 ) thus a support surface 24 is formed on which a window or door frame can be well supported.

However, in the 5 also shown that an additional adjustment device 60 can be used. The adjustment device 60 includes a threaded bolt 61 , which at the upper end has a rotatable connection 63 movable, in particular rotatable with an elbow 62 connected is. The contra-angle 62 serves to directly support a window frame 70 .

Furthermore is on the threaded bolt 61 A mother 64 attached, preferably welded to this.

In this way, by twisting the threaded bolt 61 around an axis of rotation 65 by means of the mother 64 a very simple vertical adjustment movement V of the window frame 70 realized. A vertical adjustment of the window frame 70 is also possible in a simplified manner under load, ie the window frame 70 does not have to be raised separately when adjusting. However, this assumes that the through hole 35 is designed as a threaded hole. Should be the through hole 35 not be designed as a threaded hole, are the elbow 62 and the threaded bolt 61 firmly connected to each other. About the then opposite the threaded bolt 61 twistable nut 64 can then the threaded bolt 61 including contra-angle 62 in height relative to the through hole 35 adjusted.

Finally, in the 6th yet another embodiment is shown. The only difference to the previous exemplary embodiment is a device in the figure 1' can be seen which only has a horizontal leg 20th , so has no vertical leg. This device is also very easy to handle and assemble.
