Description

The invention relates to an expansion profile for fastening anchor according to the independent claim 1. In particular, the invention relates to an expansion profile for known fastening anchor for securing a window or a door to a masonry opening.

It is known from the prior art, for fixing and fastening of building windows or building doors to use fastening anchors, which consist essentially of an anchor plate made of sheet steel, by punching and bending, and are manufactured at one end in one piece with a tab. These fastening anchors are used outside in the frame profile of building windows or building doors and pivoted so that they protrude at right angles to the interior of the gap between soffit and window out. In this state, the fastening anchors can be screwed to the masonry, whereby the building windows or building doors are attached to the latter. Depending on the size and weight of the building window to be fastened, it is customary to fasten one or more fastening anchors on each side of the frame profile. Such attachment takes place in predetermined intervals, that is, the positions of the fastening anchor are already determined by the dimensions of the building window or the building door.

The disadvantage here is that it is often found only after the onset of the frame profile in the masonry opening, that the fastening anchor in a position, such as. On a mortar, are in a secure attachment is not possible. As a result, is often completely dispensed with the attachment of the fastening anchor on the masonry, so that the frame profile of the building windows or building doors is anchored only insufficient.

Based on the above-mentioned problem, it is the object of the present invention to provide an expansion profile for fastening anchor, by which the above-mentioned disadvantages can be avoided. It is a further object of the invention to provide an expansion profile for fastening anchors, which is easy to manufacture and can also be attached overnight to known fastening anchors without further ado.

According to the invention, the abovementioned object is achieved by an expansion profile according to independent claim 1.

Accordingly, the invention relates to an extension profile for fastening anchors for fixing a window or a door to a masonry opening. The extension profile has a first attachment portion extending along a first axis and including at least one attachment member for securing the extension profile to a mounting anchor. Further, a second attachment portion is provided for attaching the extension profile to a masonry opening which extends along a second axis. The second axis is in particular aligned substantially perpendicular to the first axis.

It is expressed by the phrase "substantially perpendicular" that the two axes are preferably aligned at right angles to each other, and it is fundamentally also conceivable to align the two axes obliquely to each other. Thus, there is also an oblique alignment of the two attachment areas to one another within the scope of the invention, as long as the second attachment area can be used to create additional attachment points which are spaced from the first attachment area to a sufficient extent.

The present invention has the advantage that the installation of known fastening anchors is substantially simplified. In particular, it is no longer necessary to put the known fastening anchor after insertion of the frame profile, for example, to bypass a mortar joint of the masonry. Rather, additional fastening points are created by the special design of the expansion profile according to the invention, which are spaced from the longitudinal axis (first axis) of the fastening anchor. Furthermore, it is considered to be advantageous that the erfindungemäße extension profile can be mounted at any time on a known fastening anchor. Accordingly, an assembly of the extension profile is also possible if it is determined after the onset of the frame profile in the masonry opening, that the fastening anchors are in a position in which no secure attachment is possible. Furthermore, it follows that the building window or the building door preferably only once must be inserted into the masonry opening, whereby the risk of damaging the window or the door is significantly reduced. Of course, the expansion profile according to the invention allows immense time savings due to the ease of assembly.

Advantageous developments of the expansion profile according to the invention are specified in the dependent claims.

Thus, in a first realization of the expansion profile according to the invention, it is provided that it is flat and has a first surface for contacting the masonry and a second surface for contacting the fastening anchor along the first fastening region. The meaning of the term "flat" in this context is interpreted to mean that the extension profile has a very small thickness and thus affects the distance between the masonry and the frame of the window or the door only insignificantly. In other words, the extension profile changes the dimensions of the known fastening anchor only minimally, so retrofitting is possible at any time easily.

The at least one fastening element can be designed in particular as a projection on the second surface such that the at least one fastening element is aligned substantially perpendicular to the second surface. Due to the design of the at least one fastening element as a projection, the expansion profile according to the invention can be particularly advantageous Be connected without additional components with known mounting anchors. In detail, the at least one fastening element designed as a projection may be metal platelets which are formed integrally with the expansion profile according to the invention and can be bent by cold deformation (for example hammer blows). It is not essential that the at least one formed as a projection fastener is formed exactly perpendicular to the second surface; Rather, the projection should be designed such that it can be easily passed through openings of the existing mounting anchor. Thus, the expansion profile according to the invention can, if necessary, particularly quickly and easily used to create new attachment points for known fastening anchor.

According to a further aspect, the second fastening region has at least one opening for guiding a fastening element. Accordingly, the expansion profile according to the invention can be attached to the masonry immediately after connection to the fastening anchor, whereby time and cost can be saved. Of course, it is also conceivable that the second attachment region provides multiple openings to provide a variety of alternative attachment sites available and to ensure a strong fixation.

According to an alternative embodiment, the extension profile also has a third attachment area in addition to the first and second attachment areas. Preferably, the third attachment region, as well as the second attachment region, extends along the second axis and is arranged on a portion of the first attachment region opposite the second attachment region. In other words, the third attachment region of the expansion profile according to the invention, according to this embodiment, is point-symmetrical to the second attachment region. In this way, a particularly high stability of the expansion profile according to the invention is achieved, whereby the hold of the fastening anchor is made even safer. It should be understood, however, that the third attachment region may, of course, be axially symmetric or arbitrarily aligned with the second attachment region as long as it serves to provide additional attachment points spaced from the longitudinal axis (first axis) of the attachment anchor.

In particular, it is advantageous in this connection to equip the third fastening region with at least one opening for guiding a fastening element. Of course, the third attachment region may also have a plurality of openings for guiding fasteners in order to improve the attachment properties.

The expansion profile according to the invention is preferably made of metal. This is particularly advantageous if the at least one fastening element of the first fastening region is designed as a projection, since the at least one fastening element in this case can be formed in one piece with the rest of the expansion profile.

• Ausrichten des ersten Befestigungsbereichs entlang einer Längsachse des Befestigungsankers;
• Einführen des mindestens einen Befestigungselements in mindestens eine Öffnung des Befestigungsankers;
• Kaltumformen des mindestens einen Befestigungselements derart, dass das mindestens eine Befestigungselement in Kontakt mit dem Befestigungsanker tritt.

The present invention also relates to a method for attaching an expansion profile according to the invention to a known fastening anchor. The method comprises in particular the following steps:

• Aligning the first attachment region along a longitudinal axis of the attachment anchor;
• Inserting the at least one fastening element into at least one opening of the fastening anchor;
• Cold forming the at least one fastening element such that the at least one fastening element comes into contact with the fastening anchor.

In the following, the expansion profile according to the invention is explained in more detail by the embodiments shown in the drawings.

In the following, the same or equivalent components are provided with the same reference numerals for reasons of clarity.

In Fig. 1 a fastening anchor 1 known from the prior art is shown. These conventional fastening anchors 1 are usually used to connect the frame profile of a building window or a building door with a masonry opening. In this case, a first end of the fastening anchor (in Fig. 1 left) connected to the frame profile, while a second end ( Fig. 1 right) via one or more openings 4a, 4b, 4c, 4d, 4e attached to the inside of a masonry opening. A schematic representation of such a masonry opening is the Fig. 2 refer to. In this exemplary embodiment, the brickwork is bricks 2, which are connected to each other via mortar joints 3.

Since the fastening anchors 1 known from the prior art are usually preassembled on the frame profile of the building window or the building door (not shown), it is often found only after the insertion of the frame profile into the masonry opening that the fastening anchor is in a position in which a secure attachment is not possible. In particular, such a case is in Fig. 2 represented, in which the mounting holes 4a, 4b, 4c, 4d, 4e unfavorably come to lie exactly at the level of the mortar joint 3. In this case, with conventional mounting anchors 1 so far no sufficient support for the frame profile can be achieved without having to remove this again and move the fastening anchor.

To the known from the prior art fastening anchor 1 also for in Fig. 2 To be able to use the illustrated case, the invention proposes that in the Fig. 3a to 5 shown extension profile. A first embodiment of the expansion profile 10 according to the invention is, for example, from the FIGS. 3a and 3b seen. This has a first fastening region 11 which extends along a first axis A and has at least one fastening element 15a, 15b, 15c for fastening the expansion profile to a fastening anchor 1. In addition, the expansion profile 10 according to the invention has a second fastening region 12 which extends along a second axis B in order to fasten the expansion profile to a masonry opening. As can be seen immediately from the illustrations, the second axis B is aligned substantially perpendicular to the first axis A. Of course, it is also conceivable that in the FIG. 3a Angle α does not measure exactly 90 °. Rather, it is also conceivable that the angle α assumes a value between about 10 ° and about 170 °. It should also be noted, however, that particularly advantageous stability properties result for a substantially vertical alignment of the two axes A, B to one another.

As will be explained in more detail later, alternative fastening positions for the known fastening anchor 1 can be achieved by the second fastening region 12. Accordingly, it is no longer necessary in particular, the fastening anchor in the case of Fig. 2 subsequently postponed situation.

Like for example the Fig. 3b can be removed, the expansion profile 10 is formed flat and has a first surface 16 for contacting the masonry and a second surface 17 for contacting the attachment anchor 1, along the first attachment portion 11 on. In this case, the at least one fastening element 15a, 15b, 15c is designed as a projection on the second surface 17 such that the at least one fastening element 15a, 15b, 15c is aligned perpendicular to the second surface. As shown, it is particularly advantageous to provide the fastening region 11 with three fastening elements 15a, 15b, 15c, which are each in the form of metal platelets different shape and size are configured. The fastening elements 15a, 15b, 15c designed as a projection are designed according to the invention such that they can be easily deformed (bent over) in order to connect the expansion profile 10 according to the invention with a known fastening anchor 1. It should be expressly mentioned at this point that the fastening elements 15a, 15b, 15c can, however, also be any other conventional connecting elements (bolts, rivets, screws) which serve to fasten the expansion profile 10 according to the invention to the fastening anchor 1.

From the FIG. 3a It can also be seen that the second fastening region 12 has at least one opening 14a for guiding a fastening element (not shown). The opening 14a is of course not limited to the round hole shown, but may also be otherwise (eg. As a slot) formed. Furthermore, it is of course conceivable to provide the second fastening region 12 with a multiplicity of openings 14a.

The in the FIGS. 3a and 4a illustrated embodiments are substantially identical. For this reason, the reference numerals of respective components are each increased by "100". The only difference is that the in Fig. 4a illustrated second embodiment of the expansion profile 100 of the invention has an additional, third mounting portion 113 which extends along the second axis B. The third attachment region 113 is formed substantially identically to the second attachment region 112 and arranged on a portion of the first attachment region 111 opposite the second attachment region 112. In other words, that is in Fig. 4a illustrated second embodiment of the expansion profile 10 according to the invention, in contrast to the in Fig. 3a illustrated embodiment, mirror-symmetrically formed with respect to the first axis A. However, it is quite conceivable that the third attachment portion 113 is not aligned along the second axis B, but along a third axis (not shown), which has any angle with respect to the second axis. In this connection, it should be mentioned again that the alignment of the attachment regions 112 and 113 with respect to the first attachment region 111 need only be such as to provide additional attachment points (eg, openings 114a, 114b) spaced from the first axis A of the attachment anchor 111.

Also in the Fig. 4a illustrated third mounting portion 113 advantageously has at least one opening 114b for guiding a fastener (not shown). As mentioned above in connection with the opening 14a, the openings 114a and 114b may also be a slot or a multiplicity of openings.

The expansion profile 10 or 100 according to the invention is preferably made of metal in order to give it the necessary stability and to allow rapid assembly by cold forming of the at least one fastening element 15a, 15b, 15c, 115a, 115b, 115c.

The Fig. 5 shows a schematic view of the in Fig. 2 shown use case, wherein the in Fig. 1 illustrated known fastening anchor 1 with the from the Fig. 4a known embodiment of the expansion profile 100 according to the invention has been equipped. As can be seen, the three fastening elements 115a, 115b, 115c of the expansion profile 100 according to the invention pass through the openings 4c and 4d, respectively, of the conventional fastening anchor 1 and fasten the latter to the expansion profile 10 according to the invention. This is achieved by initially perpendicular to the second surface 117 ( Fig. 4b ) formed projections 115a, 115b, 115c after passing through the openings 4c and 4d are bent by cold forming and thus in positive / non-positive contact with the mounting anchor 1 occur.

As a result of the expansion profile 10, 100 according to the invention, it is no longer necessary to connect the openings 4a, 4b, 4c, 4d or 4e to the mortar joint 3. Rather, the second and third attachment areas 112, 113 can be used to connect the attachment anchor 1 stable with the bricks 2 of the masonry. The connection of the expansion profile 10, 100 according to the invention with the fastening anchor 1 can in particular also take place when the frame profile and thus the fastening anchor 1 is already positioned at the masonry opening.
