Description

The invention relates to a mounting device for inserting frame elements such as a frame of windows, doors or the like in wall openings of buildings, according to the preamble of claim 1.

In a known mounting device of this type ( DE 7408306 ) for holding and aligning the frame of windows, doorframes or the like in masonry, the mounting device comprises a long screw clamp as a clamping device for connection to the masonry and a short screw clamp as a holding device for connection to a window sash or door sill. The short screw clamp is slidably mounted on the guide rail of the long screw clamp, so that the window or door frame attached thereto can be positioned with respect to the opening in the masonry. To fix the window or door frame within the wall opening four such mounting devices are needed.

Furthermore, a special mounting clamp for the installation of windows and doors in shell openings is known ( DE 19923814 C1 ), which has a screw clamp with an elongated guide rail for clamping with the edge of the shell opening. On the guide rail two clamp legs are arranged displaceably and lockable, between which the window or door frame with respect. The wall opening can be fixed. There are four mounting clamps required for each installation, two for fixing the vertical frame parts, two more for fixing the frame on the window sill or a door in the lower edge.

Finally is off DE 29721077 U1 a mounting device with two oppositely acting clamping elements for their attachment to the wall and with a fastened to the frame holding member known which is adjustable parallel to a base rail by means of a threaded spindle.

It requires considerable skill and great patience until all four mounting clamps are clamped correctly within the shell opening, so that the correct connection of the window or door frame succeeds to the edge of the shell opening. In addition to a worker for attaching the mounting clamps still another worker for holding the window or door frame is required during installation.

In contrast, the present invention seeks to simplify the setting of frame members by means of a mounting device of the type mentioned, to accelerate, with only a mechanic to allow and the device as such as simple as possible, for. B. using substantially known tool elements such as clamps or the like; Furthermore, the insertion and securing of the frame elements in a wall opening of buildings, z. B. the window frame of a window in a wall opening, with restriction to only two mounting devices on opposite frame parts easily possible.

According to the invention this object is achieved by means of mounting devices of the type mentioned according to the characterizing part of claim 1, wherein two spaced mounted on a long guide rail clamp legs, seen perpendicular to the frame opening, with their free ends from a starting position within the frame or the frame opening in a End position outside the frame movable and there are detectable against the edge of the wall opening on opposite sides of the wall.

The long guide rail is pivoted about a short guide rail of a first screw clamp, which is attached to the frame. Thus, it is possible to move the frame into the wall opening free from obstruction, wherein the clamp legs of the long guide rail are pivoted inwards, ie in the direction of movement, into the frame opening. In this way, it is ensured that the clamp legs fit without abutting through the frame opening. After positioning of the frame within the wall opening then arranged on a second screw clamp leg of the long guide rail are pivoted outwardly so that they are positioned with their ends outside the wall opening in the edge region to the opposite wall surfaces indicative and there moved together against the wall surfaces and can be locked. Already with reaching the outwardly pivoted end position of the Zwingenschenkel the second screw clamp, the frame to be mounted can not fall out of the wall opening. The assembly can be carried out by only one fitter who operates after the insertion of the frame into the wall opening into only two fixed to opposite frame parts clamp tools in such a way that the ferrule each leg of the second screw from its initial position in its end position, based on the edge region of the wall opening to be pivoted. Only when reaching their final position will the fitter collapse the ends of the clamp legs of the second screw clamps in the respective edge region of the wall opening and fix the two clamp tools at the same height by turning the respective screw handle of the second screw clamps.

According to the invention, the hinge legs are provided for pivoting that a hinge axis of a hinge fastened to the short guide rail of the first screw clamp runs parallel to the short guide rail, so that the long guide rail of the second screw clamp describes a circular path about the short guide rail when pivoting about the hinge axis.

It is expedient that a bearing part of the hinge adjacent to a provided at the free end of the short guide rail fixed clamp legs of the first screw clamp is attached to the guide rail, so that so that the adjustment of the displaceable on the first guide rail clamp leg of the first screw is as large as possible.

Advantageously, the pivot bearing of the hinge on a bearing plate with stop surfaces to the frame, which are preferably adapted to the frame profile.

Particularly advantageously, the stop surfaces form a right angle to the frame profile open, so that the contact position of the fixed clamp leg at the end of the guide rail of the first screw clamp can be easily found during assembly before the first screw clamp is screwed to the frame.

To the frame indicative stop surfaces can protect the frame surface with a protective layer, for. B. cork, be provided.

According to a further embodiment of the invention it is provided that the hinge has a pivotable hinge part has, in which the long guide rail is guided longitudinally displaceable. The long guide rail is thus in a simple manner with the attached at its free end clamp legs in the direction of movement behind the distal edge of the wall opening displaced, so that the ferrule of the second screw clamp there is free to pivot into its final position and against the wall lockable.

To improve the operability of the pivoting of the guided in the pivotable hinge part long guide rail is provided in a further embodiment of the invention that the pivot bearing has stops for limiting the pivotal movement of the pivotable hinge part in the starting position and in the end position of the long guide rail.

Finally, a further simplification of the assembly can be achieved in that the pivotable hinge part has a clamping screw, with which the long guide rail can be locked in each case in a predetermined longitudinal position. As a result of this configuration, the longitudinal position of the long guide rail can be fixedly adjusted in adaptation to the wall thickness in the edge region of the wall opening. For several wall openings of a building so that only a single adjustment of the longitudinal position is required.

In the following an embodiment of the invention will be explained with reference to the drawing. Show it

• FIG. 1 a view of a frame to be set with two attached clamp tools, in perspective view;
• FIG. 2 a perspective view of the left clamp tool according to FIG. 1 in its starting position;
• FIG. 3 a perspective view of the right-hand clamping tool according to FIG. 1 in its final position;
• FIG. 4 a schematic side view of the frame with the ferrule tool in the final position.

FIG. 1 shows a frame 1 to be placed in a wall opening in the form of a window frame or window frame. At the opposite vertical frame parts of the frame 1, a ferrule tool (2, 4) is attached to the frame 1 respectively. In the frame assembly of the frame 1 is moved together with the two attached thereto Zwingenwerkzeugen in the wall opening of a building and there in an approximate end position initially placed on auxiliary support parts, such as wooden wedges or the like. The parked frame is then located approximately centrally within the wall opening, so that its outer contour extends circumferentially at a distance from the inner contour of the wall opening.

The two ferrules 2, 4 are similar and mutually mirrored. The left ferrule tool 2 has a first screw clamp 3, with which it is attached to the left vertical part of the frame 1. The right-hand clamp tool 4 has a first screw clamp 5, with which it is attached to the right vertical part of the frame 1.

In a further agreement, both forceps tools 2, 4 each have a second screw clamp 6, 7, each with a long guide rail 8, 9, which in each case is attached to a pivot bearing 10, 11 attached to the first screw clamp from an initial position, as shown by the example of the left clamp tool 2 , in an end position, as shown to the right-hand clamping tool 4, is pivotable. The clamp legs 12, 13 of the second screw clamps 6, 7 are thereby pivoted from a position within the opening of the frame 1 in a position outside the frame 1. Accordingly, the clamp legs 12 of the left clamp tool 2 in the counterclockwise direction, the clamp legs 13 of the right clamp tool 4 in the clockwise direction about the pivot bearing 10, 11 are pivotable.

Both the first 3, 5 and the second screw clamps 6, 7 of the clamp tools 2, 4 may advantageously be formed in the manner of conventional commercially available screw clamps, ie they each include a guide rail with a fixed clamp leg at one end and along the guide rail adjustable second clamp leg. The adjustable second ferrule has a threaded bore for a threaded spindle, at one end of a rotary handle is attached and at the other end, which is located on the opposite side of the rotary knob threaded bore, a stop member, preferably rotatably mounted pivotally about a ball joint.

Thus, the structural complexity of each of the forceps tools 2, 4 is limited essentially to two clamps, one with a short, the other with a long guide rail, the screw clamps 6, 7 with long guide rail 8, 9 each have a pivot bearing 10, 11 with the short guide rail of a first screw clamp 3, 5 are pivotally connected.

The respective pivot bearing 10, 11 has for this purpose a hinge with a pivotable hinge part 25, in which the long guide rail 8, 9 is guided longitudinally displaceable.

FIG. 2 Its first screw 3 engages with its short guide rail 14 and its two clamp legs 15, 16, the vertical part of the frame 1, wherein the displaceably arranged on the window inner side leg 16 by means of the rotary handle 17 against the clamp leg 15 at the end of the short guide rail 14 is clamped. On the short guide rail 14, immediately adjacent to the end-side ferrule 15, the pivot bearing 10 is fixed, the lateral transverse web 18 on the short guide rail 14 z. B. is fixed by welding or by means of a screw connection. The pivot bearing 10 has a hinge with a hinge axis 19 about which the pivotable hinge part 25 is pivotable. The pivotable hinge part 25 forms a longitudinal guide for the long guide rail 8, which is adapted to the profile of the long guide rail 8 and this includes in whole or in part. The displacement position of the long guide rail 8 can be fixed with respect to the longitudinal guide by means of a clamping screw 22.

The hinge axis 19 is mounted in a fixed hinge part 20 which is fixed to a bearing plate 21 of the pivot bearing 10.

So that one can easily find the contact position of the first screw clamp 3 on the vertical part of the frame 1, the frame 1 facing side of the bearing plate 21 is formed as a stop surface to the frame 1, that is adapted to the frame profile. Particularly advantageous is the in FIG. 2 shown right angle shape of the bearing plate 21, which rests on the frame 1 on two sides.

FIG. 3 shows, based on FIG. 1 , a perspective view of the right-hand ferrule tool 4. As in FIG. 1 the wall opening itself is not shown, but only a corresponding section of the frame 1, seen from the inside to the outside. On the short guide rail 14 of the first screw 3, the pivot bearing 10 is fixed by means of the transverse web 18. The fixed to the guide rail 14 of the first screw 3 at the end of the clamp leg 15 is located with its covered end from the outside of the frame 1, either directly or on the pivot bearing 11, if the bearing plate 21 as in Fig. 3 represented forms a right angle.

On the adjoining the bearing plate 21 free portion of the short guide rail 14 of the movable clamp leg 16 of the first screw 5 is shown, which can be clamped by pressing the rotary handle 17 of the screw 5 with the inner surface of the frame 1. For clamping serves an actuatable by means of the rotary handle 17 threaded spindle 23, which in one at the inner end of the displaceable Zwingenschenkels 16 of the first screw 5 engages provided threaded hole and at the front end of a contact disk 24 is attached.

Above the first screw 5 is the pivoted to its end position guide rail 9 of the second screw clamp 7. On the long guide rail 9 of the second screw clamp 7 two clamp legs 13 are arranged; one of which is fixed at the end and located on the outside of the wall opening; the second is slidably mounted on the long guide rail 9 within the frame 1. Both clamp legs 13 of the long guide rail 9 are clamped in their final position against the outer or inner surface f1, f2 of the wall and thus define the installation position of the frame inserted into the wall opening 1. In this installation position, the frame 1 at its outer periphery to the inner Edge of the wall opening connected, z. B. by foaming or filling the cavities with mortar.

In FIG. 3 are opposite wall surfaces f1, f2, which describe the edge around the wall opening outside the frame 1, shown schematically. Against the outer wall surface f1, the free end of the associated clamp leg 13 of the second screw clamp 7 is supported; against the wall surface f2 of the wall inside the bearing plate 26 is supported at the end of a threaded spindle 27 which is rotatable in a threaded bore in the free end of the displaceable clamp leg 13 of the second screw clamp 7 by means of a (not shown) rotary handle. In this way, the frame 1 to be inserted into the wall opening is fixed to the opposite wall surfaces f1, f2.

FIG. 4 shows to further illustrate the mounting device according to the invention a schematic side view of the ferrule tool 4 in the installed position of the frame 1 according to FIG. 3 , where the total wall thickness of the wall of a building is shown. It can be seen the arrangement of the first screw 5 with rotary handle 17 below the second screw 7 with truncated rotary handle 28. Furthermore, the two clamp legs 15, 16 of the short guide rail 14 are shown for the first screw 5. The first screw 5 is clamped to the frame 1 between the fixed clamp leg 15 and the adjustable clamp leg 16, wherein at this an investment disc 24 is rotatably mounted.

On the short guide rail 14 of the first screw 5, the pivot bearing 11 is attached. A bearing plate 21 is fastened by means of a transverse web 18 on the short guide rail 14 by means of screws 27. A hinge with hinge axis 19, a pivotable hinge part 25 and a fixed hinge part 20 is also attached to the bearing plate 21, wherein the pivotable hinge part 25 is pivotable about the axis of rotation 19 between two end positions. In the Fig. 4 shown end position corresponds to the end position of the clamp legs 13 according to Fig. 3 ,

In the (not shown) other end position are each the Zwingenschenkel 12, 13 of the long guide rails 8, 9 within the frame opening, so that the frame 1 can be pushed into the wall opening obstacle-free with attached clamp tools 2, 4. For pushing in there are thus the Zwingenschenkel 12, 13 both forceps tools 2, 4 in their starting position, as in Fig. 2 shown.

As soon as the full insertion depth is reached when inserting the frame 2 equipped with both clamp tools 2, 4 into the wall opening, the long guide rail 8, 9 of both clamp tools 2, 4 is pivoted from its initial position into the end position, as in FIG FIG. 1 is shown on the right side of the frame. In this end position, both forceps tools 2, 4 are clamped on both sides with the wall surface in the edge region of the wall opening, so that the frame 1 is fixed within the wall opening. Here are the in FIG. 4 shown in the side view of clamp legs 13 of the long guide rail 9 against the outer surfaces f1, f2 clamped together on both sides of the wall. By means of the clamping screw 22, the long guide rail 9 is clamped to the pivot bearing 11, so that the distance between the pivot bearing 11 and the outer surface f1 is fixed. Thus, with a given wall thickness, the engagement and clamping of the second screw clamp 7 with respect to the wall surfaces f1, f2 can be simplified.

The handling of the mounting device according to the invention can be further facilitated by the fact that the pivot bearing 10, 11 stops for limiting the pivotal movement of the pivotable hinge part 25 in the starting position and in the end position of the long guide rail 8, 9. Such stops can be advantageously achieved by a suitable shaping of the pivotable hinge part 25 by the outer contour of the pivotable hinge part 25 cooperates with the surface of the bearing plate 21 in each case in the manner of a stop.
