Abstract

The invention relates to a device for aligning window or door frames (3) in wall openings (2) by means of clamping wedges (4a, 4b) which are clamped between the frame (3) and the wall opening (2) to a greater or lesser depth parallel to the frame plane in order to hold the frame (3) in desired, in particular vertical, alignment in the wall opening (2), wherein the clamping wedges (4a, 4b) are each combined in pairs to form clamping wedge pairs (4) in that two clamping wedges (4a, 4b) with the same wedge angle bear against one another so as to be displaceable in opposite directions along their oblique wedge surfaces, whereas their outer base surfaces (4a', 4b') are intended to bear against a reveal of the wall opening (2) or against the opposite outer side of the frame (3), wherein the clamping wedges (4a, 4b) of a clamping wedge pair (4) are guided so as to be displaceable relative to one another in the displacement direction by means of guide strips and are secured against deflection in the transverse direction, and wherein the clamping wedges (4a, 4b) have projections (14a, 14b) protruding approximately transversely to their displacement direction and intended for introducing the displacement forces, and, with the clamping wedge pair (4) inserted between the frame (3) and wall opening (2), these projections (14a, 14b) can come to bear against an outer side of the frame (3). It is essential here that the projections (14a, 14b) have a stop (15a) which is dimensioned such that, when bearing against the outer side (3a) of the frame (3), it positions the clamping wedges (4a, 4b) without lateral overhang with respect to the frame outer side (3a) and that the projections (14a, 14b) are connected to their clamping wedges (4a, 4b) via predetermined breaking points (14a', 14b').

Description

Method and device for aligning window or door frames

description

The invention primarily relates to a device for aligning window or Door frame in wall openings by means of clamping wedges, which are clamped between the frame and the wall opening more or less deep parallel to the frame plane to the frame in desired, especially vertical, alignment in the To hold wall opening, wherein the clamping wedges are combined in pairs to wedge pairs by two clamping wedges with the same wedge angle along their sloping wedge surfaces in opposite directions against each other lie, while their outer ßere base surfaces to bear against a leasing of the wall opening or at the opposite Outside the frame are determined, wherein the clamping wedges of a clamping wedge pair are guided by guide rails in the displacement relative to each other displaceable and secured against dipping in the transverse direction, and wherein the clamping wedges approximately transversely to their direction protruding projections for introducing the Ver have sliding forces and these protrusions at between the frame and wall opening plugged clamping wedge pair on a Au ßenseite the frame can come into abutment.

Such a device has become known from WO 2005/068762 A1. The lateral overhangs have the task to move the two clamping wedges against each other.

Furthermore, the aforementioned prior publication shows that the two clamping wedges can be connected to each other by a flexible band. This band serves to pull out the clamping wedges after the window or door frame has been stably mounted in its wall opening.

On this basis, the present invention based on the object to improve the alignment process by means of clamping wedges in that a precise adjustment of the frame is ensured. It should also be possible to dispense with pulling out the clamping wedges after installation of the frame.

This object is achieved in that the projections have a stop which is dimensioned so that it positioned at clamping on the outside of the frame, the clamping wedges without lateral projection relative to the frame outside, and that the projections connected via predetermined breaking points with their clamping wedges are .

This initially results in the advantage that the clamping wedges can be inserted accurately due to the stop having projections in the gap between soffit and frame, because when the abutment of the stop on the frame outer side ensures that the clamping wedges relative to the frame outside - In contrast to the WO 2005/068762 A1 - no longer project laterally, but disappear completely in the gap. As a result, the clamping wedges do not need to be removed after assembly of the frame to who, and it eliminates the filling of the resulting when pulling out of the clamping wedges gaps with mounting foam oa. The wedges remain so after installation in the gap and thus serve not only as an assembly aid but also as lasting blockage of the window frame in the soffit and thus give the frame additional stability.

Furthermore, the invention has the advantage that the lateral projections, which are necessary for oppositely moving the clamping wedges, can be removed quickly and easily after mounting the frame over their predetermined breaking points. So there are no protruding parts left and the gap between soffit and frame can be easily closed by cover strips.

In a further development of the invention, it is recommended that the lower edge of the collars from at least approximately aligned with the voltage applied to the soffit base of the wedge. This achieves a support of the wedge in the transverse direction, in particular against a tilting of the wedge about his Longitudinal axis. This is especially relevant if the window frame does not provide a broad contact surface for the wedge, especially if it has circumferential grooves or if the soffit is not flat and even.

As a result, the lateral projections thus ensure not only the exact insertion depth of the clamping wedges relative to the window or door frame, but also their horizontal orientation in the transverse direction.

Since the projections are exposed to considerable forces for wedging the clamping wedges, it is recommended that they have an approximately extending in the direction of extension and are supported on this extension in the direction of displacement on the wedge. Preferably, this extension is at least predominantly distanced with respect to its associated clamping wedge with minimal play, so that the desired breaking point between projection and clamping wedge is not affected.

For the structural design of said predetermined breaking points, it is recommended that the projections are connected only by small spacers with their clamping wedges, but otherwise distanced from their clamping wedge, so that these spacers act as predetermined breaking points.

It is particularly expedient in this context if the clamping wedges have local depressions and the predetermined breaking points are arranged in these depressions. This will ensure that no material stubs remain on the wedge after breaking off the projections, which protrude from the frame.

A particularly useful design of the predetermined breaking points is that they are designed for torsional fracture. This offers the advantage that when breaking the predetermined breaking points only torsional forces acting on the clamping wedges, so no horizontal forces through which the clamping wedges could possibly be pushed out of its desired position. With regard to the guidance of the two clamping wedges of a clamping wedge pair, it is recommended that a clamping wedge on its wedge surface has at least one projection, whereas the other clamping wedge of the same Klemmkeil- pair has on its wedge surface a projection corresponding to this, running in the longitudinal direction recess. It is particularly useful in this context, if the projection and the recess have a rear handle, in particular as a dovetail guide are formed because the two clamping wedges then can not fall apart in the transverse direction. This effect can also be enhanced by the fact that the rear grip, in particular the dovetail guide is realized with a tight fit, so the two clamping wedges so quasi frictionally related and also do not fall apart in the longitudinal direction.

Preferably, the guide on both clamping wedges open on both sides, that is formed without an end stop, so that the wedges can be pushed together beyond their actual length. Thus, the upper wedge over the length of the lower wedge addition to be pushed past this. This allows a much greater height compensation than if the wedges were pushed together only to their simple length.

Suitably, several different levels of clamping wedge pairs are combined in a set, since the thickness of the gap between the frame and wall opening can vary greatly.

Finally, there is the possibility that the clamping wedges have on their wedge surface at least local roughening, in particular transverse ribs. You can thereby have a steeper wedge angle, without any mutual slippage of the clamping wedges is to be feared due to high lateral forces.

It is also advantageous if the clamping wedges have a width of not more than 2 cm, preferably 1 cm or less. Secondarily, the invention also relates to the use of the described clamping wedge pair for aligning glass sheets within the window frame. The Applicant reserves the right to formulate protection claims directed thereto, in which case essentially only the term "wall opening" is to be replaced by "door or window frame" and the term "frame" is to be replaced by the term "glass pane".

Further features and advantages of the invention will become apparent from the following description of exemplary embodiments and from the drawing; showing:

Presentation of its breaking point.

1 shows a wall 1 with a wall opening 2. In this wall opening 2, a window frame 3 is inserted with the usual gap. The Fens terrahmen 3 is formed at right angles in the embodiment. Of course, the wedge-clamping invention also comes in frames with a round or oblique contour used. Figure 1 shows the horizontal orientation on the underside of the window frame 3, wherein only one clamping wedge pair 4 is shown here. An equal

Clamping wedge pair is also located under the right, not shown end portion of the window frame. 3

The clamping wedge pair 4 consists of two clamping wedges 4a and 4b, both of which have the same wedge angle and lie along their oblique wedge surfaces together, while their outer base surfaces 4a 'and 4b' are horizontal and at the wall opening 2, more precisely at the reveal on the one hand and on the outside of the frame 3 on the other. The clamping wedges 4a and 4b extend in the plane of the frame and are displaceable along this plane.

For leveling the frame, the clamping wedges 4 a and 4 b and / or the clamping wedges, not shown under the right end of the window frame are moved in opposite directions so that the frame 3 is aligned exactly horizontal on its underside. Then, in a corresponding manner, the alignment on the other sides of the frame and the fixation in the masonry by adjusting screws. 5

It can be seen in FIG. 1 that the two clamping wedges 4a and 4b each have at their thicker end a projection 14a or 14b projecting laterally outwards. These two projections are outside the gap between the wall and window frame and are therefore easy to reach from the outside. They allow the clamping wedges 4a and 4b inserted in the gap to be handled comfortably and the two clamping wedges to be pushed together so far that the clamping wedge pair supports the frame 3 at the desired height.

Further details of the clamping wedges emerge from FIGS. 2 to 4. It can be seen in particular that the one clamping wedge - in the exemplary embodiment the lower clamping wedge 4 a - on its wedge surface has a projection 24 a running in the direction of displacement, ie in the longitudinal direction, compare in particular FIGS 3b, has. This projection has a dovetail-shaped cross section and corresponds to a corresponding groove-shaped recess 24b in the wedge surface of the upper clamping wedge 4b, see in particular Figure 4a and b. Said groove-shaped recess 24b extends in the longitudinal direction through the clamping wedge 4b and also has a dovetail-shaped cross-section, corresponding to the projection 24a. This means that the projection 24a engages behind the recess 24b when the clamping wedges 4a and 4b are pushed together. The clamping wedges 4a and 4b are therefore in positive engagement and can only be moved in the longitudinal direction relative to each other. So that they do not slip apart during transport and assembly, a relatively tight fit between the projection 24a and the recess 24b can be selected, so that slight frictional forces must be overcome in order to move the clamping wedges relative to each other.

As shown in FIGS. 3a and 3b, the projection 24a flattens towards the thicker end of the clamping wedge. This flattening 24a 'is used for Min imation of the height of the clamping wedge pair when the clamping wedges are moved apart.

Finally, Figures 3b and 4b show that the wedge surfaces of the clamping wedges have a corrugation 34a and 34b transversely to the direction of displacement of the clamping wedges. This corrugation prevents inadvertent slippage of the clamping wedges during alignment and assembly of the frame, especially when the fastening screw 5 is drilled through the clamping wedge pair.

After assembly of the frame, the lateral projections 14a and 14b are no longer needed and can be removed from their respective clamping wedge. Expediently, predetermined breaking points 14a 'are provided for this purpose, which have sufficient rigidity in the direction of displacement, but yield slightly in other directions, in particular in the case of torsion. In particular, a twisting off of the projections 14a and 14b is possible.

As FIGS. 3 a and 3 b show, the projections 14 a are connected to their clamping wedge 14 via narrow intermediate pieces 14 a '. These spacers cause a distancing of the projection 14a relative to its clamping wedge. As a result, the projections can serve as a stop when the Klemmkeil- pair is inserted perpendicular to the frame in the gap between the frame and wall opening. In addition, the intermediate pieces 14a 'act as a predetermined breaking point.

In addition, it can be seen in FIGS. 3 b and 4 a that the lateral projections 14 a and 14 b each have an extension 1 7 a or 1 7 b extending in the direction of displacement. This extension is expediently not directly connected to its associated clamping wedge 4 a and 4 b, but only with its projection. In this way, the extensions allow 1 7a and 1 7b, the introduction of the required forces for moving the clamping wedges, without complicating the subsequent cancel, in particular twisting, the projections of their clamping wedges.

After breaking off the projections 14a and 14b are both clamping wedges 4a and 4b completely within the gap between the frame and soffit and impede in any way the subsequent foaming, grouting and attaching a cover strip

Figure 5 shows a vertical section through the lower clamping wedge 4a to illustrate the arranged between it and its projection 14a predetermined breaking point 14a '.

It can be seen that the predetermined breaking point 14a 'has been emaciated to a small neck piece compared with Figures 2 and 3 and that the clamping wedge 4a has a recess, ie a recess 4a "in the area of the predetermined breaking point There is no laterally protruding parts on the pair of clamping bodies after breaking off the lateral projections 14a or 14b, and the gap between the masonry and the window or door frame can be clean with it a cover strip to be closed. It is also essential that the neck piece 14a 'has an approximately dumb-shaped cross-section. As a result, the predetermined breaking point can be released by torsion of the projection 14a about a rotational axis passing horizontally through the neck piece 14a '. This formation of the predetermined breaking point as a torsion break point has the advantage that no forces are exerted in the direction of displacement on the clamping wedges when breaking off the lateral projections. This is further facilitated by the fact that the neck piece 14a 'is the only cohesive connection between clamping wedge and projection and that otherwise the projection is slightly distanced relative to the clamping wedge.

Furthermore, it can be seen in FIG. 5 that the projection 14a has a stop 1a on its side facing the clamping wedge. This is positioned so that it comes into contact with the door or window frame when inserting the wedge system in the gap between the window or door frame on the one hand and the soffit on the other. Due to the fact that this stop 1 5a is aligned approximately with the outside of its associated clamping wedge, preferably even slightly offset outwards, the stop ensures that the clamping wedges are completely inserted into the said gap, ie no lateral projection with respect to the outside of the frame form . The stop 1 5a is thus an essential positioning aid when installing the wedge system.

Finally, Figure 5 illustrates that the projection at its lower edge 1 6a with the base 4a 'of its associated clamping wedge 4a is approximately aligned, at least not projecting downwards. This allows the lower edge 16a also contribute to the stabilization of the wedge system during installation.

As a result, the invention thus leads to a significant ease of alignment with high accuracy. In addition, the clamping wedges can be built very narrow due to their non-tilting support on the lateral projections; They are therefore particularly well suited for installation with Kompribändern. For assembly with seals from Kompriband it is also expedient that the clamping wedges have a maximum width of 2 cm, preferably of a maximum of 1 cm. Thus, the clamping wedges come into contact only in the front region of the window frame and are thus in front of the Kompriband- seal, which is laid between the window frame and reveal.
