Band arrangement for fastening doors or windows

The invention relates to a hinge arrangement, in particular a concealed hinge arrangement, for fastening doors or windows that can be rotated about a hinge axis, having a cassette and a hinge bracket arranged partially in a receiving area of the cassette, the hinge axis being arranged parallel to a vertical direction, the Hinge bracket is inserted into the receiving area along a horizontal direction orthogonal to the vertical direction. Furthermore, the invention relates to a method for assembling a belt arrangement. Such band arrangements are known from the prior art and are used for the rotatable mounting of a wing of the door or window on a frame of the door or window. Hinge arrangements typically have a sash-side hinge strap and the frame-side hinge bracket, which is mounted in a frame-side receptacle such that it can pivot about the hinge axis. In order to increase the aesthetic effect and for optimal utilization of the available space, parts of the hinge arrangement, in particular the hinge strap and the receptacle, can be arranged in recesses in the sash and the frame. When the door or window is closed, the entire hinge arrangement is arranged within the recesses of the wing or the frame, so that the hinge arrangement is not visible from the outside. When the door or window is open, only part of the hinged bracket is gels arranged outside the recesses. Here, the expert speaks of concealed hinge arrangements. Concealed hinge arrangements are known from the prior art, in which the hinge bracket is inserted and fastened in a cassette arranged in the recess of the wing. This ensures that the sash is securely fastened to the frame and that the force is transmitted over a large area from the sash to the frame.

The problem with the assembly of tape assemblies is usually to organize the hinge bracket in the cartridge. Difficulties in inserting the hinge leaf into the cassette with pinpoint accuracy arise due to the sometimes not low weight of the sash, the necessary accuracy and the typically suboptimal installation conditions on construction sites.

The invention is therefore based on the object of further developing a hinge arrangement, in particular a concealed hinge arrangement, in such a way that the assembly of the leaf on the frame and in particular the arrangement of the hinge bracket in the cassette is facilitated.

This object is solved by the tape arrangement reproduced in claim 1 ge.

According to the invention, the cassette has a lug in the receiving area for engaging in a recess in the hinge bracket and for holding the hinge bracket. In this way, it is possible in an advantageous manner that the wing with the hinge bracket is initially hung on the lug of the cassette when the tape arrangement with the cutout is installed. The hinged leaf can then be aligned in such a way that the hinge bracket is positioned exactly in the receiving area of the cassette. Advantageously, little force has to be used here, since the weight of the sash is already absorbed by hanging it on the hinge bracket and the cassette on the frame. Furthermore, this makes it possible in an advantageous manner for the hinge bracket to be forced into its intended position in the receiving area of the cassette by the engagement of the lug in the recess. He inventive band arrangement simplifies the assembly so that the Bandan arrangement can be mounted easily and without difficulty with just one person can. Provision is preferably made for the nose to be arranged on an upper inner side of the receiving area of the cassette.

Advantageous refinements and developments of the invention can be found in the dependent claims and in the description with reference to the drawings.

According to a preferred embodiment of the invention, it is provided that the lug has a first flank along the horizontal direction and a second flank arranged following the first flank, the first flank having a smaller incline than the second flank. In terms of the present invention, the lug is a lug protruding into the receiving area of the cassette. It is therefore clear to the person skilled in the art that the first flank has a directional component into the recording area and the second flank has a directional component out of the recording area. In particular, it is provided that the first flank has a slope in the vertical direction and that the second flank has a slope counter to the vertical direction. This ensures in an advantageous manner that the hinge bracket can easily be inserted into the receiving area of the cassette via the lower gradient of the first flank, but that the hinge bracket is nevertheless securely secured in the suspended position by the greater gradient of the second flank. In the context of the present invention, the fact that the hinge bracket is pushed into the cassette merely means that the hinge bracket and the cassette are pushed into one another relative to one another. On the one hand, it is conceivable that the cassette is moved in order to insert the hinge bracket into the receiving area of the cassette. However, it is also conceivable that the hinge bracket is moved to slide it into the cassette. A flank within the meaning of the present invention can be straight, concave or convex. In particular, it is provided that both the first flank and the second flank are straight. However, it is also conceivable that the first flank is straight, concave or convex and the second flank is straight, concave or convex.

An embodiment of the present invention is particularly preferred, in which it is provided that a section plane is spanned by the vertical direction and the horizontal direction, with the nose relative to the section has a triangular shape, the recess preferably having a shape complementary to the nose in relation to the cutting plane. This makes it possible in an advantageous manner that the hinge bracket is securely hung with the nose of the recess. Due to the weight acting on the sash and thus on the cassette and the hinge bracket, the cassette is secured with the lug in the suspended state on the hinge bracket. The triangular shape of the nose prevents the hinge bracket from slipping off. Alternatively, it is conceivable for the nose to have the shape of a semicircle, a semiellipse or a semioval in relation to the cutting plane. For this purpose, it is also preferably provided that the recess has a shape that is complementary to the nose in relation to the cutting plane. Due to the shape of the recess, which is complementary to the nose, the hinge bracket is secured by a positive fit between the nose and recess. It is preferably provided that the length of the nose in the horizontal direction corresponds to approximately two thirds of the length of the receiving area in the horizontal direction. It is particularly preferable that the apex of the triangular shape is provided at half the length of the receiving area in the horizontal direction.

According to a further preferred embodiment of the invention, it is provided that the cassette has a further lug in the receiving area and the hinge bracket has a further recess, the further lug being arranged opposite the lug, the further recess being arranged opposite the recess, the another lug along the horizontal direction preferably has a first flank and a second flank arranged after the first flank, the first flank having a smaller gradient than the second flank, the further lug particularly preferably having a triangular shape in relation to the section plane has, wherein the further recess based on the cutting plane preferably has a shape complementary to the further nose. Due to the lug, the further lug and the recess and the further recess, the hinge arrangement can be used for doors or windows hinged on the left as well as for doors or windows hinged on the right. The nose is preferably provided on the upper inside of the receiving area of the cassette and the further nose is provided on a lower inside of the receiving area of the cassette. Opposite within the meaning of the present invention refers here to an opposite in the vertical Direction. In terms of the present invention, the additional lug is an additional lug protruding into the receiving area of the cassette. It is therefore clear to the person skilled in the art that the further first flank has a directional component into the receiving area and the further second flank has a directional component out of the receiving area. In particular, it is provided that the further first flank has a slope counter to the vertical direction and that the further second flank has a slope in the vertical direction. Another flank within the meaning of the present invention can be straight, concave or convex. In particular, it is provided that both the further first flank and the further second flank are straight. However, it is also conceivable that the further first flank is straight, concave or convex and the further second flank is straight, concave or convex. It is also conceivable that the further lug has the shape of a semicircle, a semi-ellipse or a semi-oval in relation to the sectional plane, it also being preferably provided that the further recess has a shape complementary to the further lug in relation to the sectional plane.

For this purpose, it is preferably provided that the further nose and the further recess are spaced apart from one another in the vertical direction. In particular, it is provided that the further lug and the further recess are spaced apart by a distance which corresponds at least to the height of the further lug in the horizontal direction and is preferably greater.

It is conceivable that the nose and preferably the further nose have a surface made of a plastic. This ensures in an advantageous manner that when the hinge bracket is pushed into the receiving area of the cassette, the hinge bracket is easily routed over the nose and therefore little effort is required to mount the belt arrangement. The nose can be made of a plastic. Furthermore, the additional nose can be made of a plastic.

For secure attachment of the hinge bracket in the receiving area of the cassette, it is preferably provided that the hinge bracket has a threaded bore, the cassette having a through-hole, the band arrangement having a through-hole inserted into the threaded bore. Screwed screw for attaching the hinge bracket to the cassette has. In this way, it is advantageously possible for the hinge bracket to first be pushed into the receiving area of the cassette and for the cassette to be secured by hooking the lug of the cassette onto the recess in the hinge bracket. The wing can then be easily positioned so that the cassette is in its intended position relative to the hinge bracket. If the cassette is arranged in its intended position, the wing can be secured in its correct position by screwing the screw through the through-bore of the cassette into the threaded bore of the hinge bracket.

For this purpose, it is preferably provided that the further nose and the further recess are spaced apart in the vertical direction by a distance, the hinge bracket having a further threaded bore, the white direct threaded bore being offset from the threaded bore counter to the vertical direction by the distance. This ensures in an advantageous manner that the hinge bracket can be secured in the cassette by screwing in the screw both in the case of a hinge arrangement hinged on the left and in the case of a hinge arrangement hinged on the right.

According to a further preferred embodiment of the present invention, it is provided that the tape arrangement has an upper housing part and a lower housing part, the cassette being arranged in an interior space formed by the upper housing part and the lower housing part. Provision is preferably made for the upper housing part and the lower housing part to be screwed together. Provision is particularly preferably made for the upper housing part and/or the lower housing part to be fastened, preferably screwed, to a wing or a frame. This makes it possible in an advantageous manner that the cassette and the cassette with the hinge bracket can be moved independently of the attachment of the hinge assembly to the wing or the frame be.

Another object to solve the problem is a Ver drive for mounting a tape assembly according to the invention, wherein the crowd nierbügel is partially arranged in the receiving area of the cassette, wherein the Hinge bracket is arranged in the receiving area of the cassette that the nose engages in the recess. As a result, a simple and safe mounting of the band arrangement is ensured in an advantageous manner.

For this purpose, it is preferably provided that the screw is screwed through the through hole into the threaded hole in order to fasten the hinge bracket.

Fig. 3: an illustration of the belt arrangement shown in Fig. 2 in montier ter form.

FIG. 1 shows a sectional view of a hinge arrangement 100 according to an exemplary embodiment of the present invention for fastening a door or a window so as to be pivotable about a hinge axis. The Bandan arrangement 100 comprises an upper housing part 1 which is screwed to a lower housing part 2 . In one formed by the upper housing part 1 and the lower housing part 2 formed interior is a cartridge 3 of the tape assembly 100 is arranged.

The upper housing part 1 is screwed to a wing of a door or window, not shown. The hinge arrangement 100 shown here is what is known as a concealed hinge arrangement 100. The person skilled in the art understands a concealed hinge arrangement 100 to mean a hinge arrangement 100 in which the hinge axis is arranged in a recess in the frame. Preferably, the upper housing part 1 and the lower housing part 2 are arranged in a recess of the wing. For the sake of clarity, the part of the hinge bracket 4 that is arranged in the recess of the frame is not shown.

In a receiving area 9 (see Figure 2), a hinge bracket 4 of Bandan order 100 along a horizontal direction H is inserted. The crowd nierbügel 4 is intended to be connected by a pin or pin with a wide ren not shown part for fastening the door or window, example, a receptacle which is arranged in a recess of the frame to the hinge axis to be pivotally connected . In the illustration shown here, the hinge axis is perpendicular to the plane of the paper. The crowd nierbügel 4 is secured with a screw 11 in the cassette 3. For this purpose, the screw 11 is screwed through a through hole 7 of the cassette 3 with the crowd 4 nierbügel.

The horizontal direction H and the hinge axis, which is orthogonal to the horizontal direction H, span a sectional plane S.

FIG. 2 shows a schematic view of the belt arrangement 100 shown in FIG. 1 according to an exemplary embodiment of the present invention in a perspective representation.

The upper housing part 1, the lower housing part 2, the cassette 3 inserted into the interior space formed by the upper housing part 1 and the lower housing part 2, and the hinge bracket 4 pushed into the receiving area 9 of the cassette 3 along the horizontal direction H are shown. Taking area 9, the upper housing part 1 and the lower housing part 2 were drawn in two places A transparent.

A nose 5 of the cassette 3 formed in a triangular shape can be seen through the transparently drawn points A. The lug 5 engages in a recess 6 of the hinge bracket 4 which is formed complementarily to the lug 5 . This makes it possible in an advantageous manner, the hinge bracket 4 first in the receiving area 9 to insert and this after arranging in the receiving area 9 by screwing the screw 11 through the threaded hole 8 in the receiving area 9 to secure. Due to the fact that the cassette 3 is already hooked in by the engagement of the lug 5 in the recess 6 on the hinge bracket 4, the mounting of the tape arrangement 100 is significantly simpler and can be done by just one person without any difficulties.

The length of the nose 5 in the horizontal direction H is approximately two-thirds of the length of the recording area 9 of the cassette 3.

The nose 5 is shaped asymmetrically. Along the horizontal direction H, the nose 5 initially has a first flank 5.2 up to the tip 5.1 of the triangular shape with a slope along the vertical direction V parallel to the hinge axis. In the horizontal direction H after the tip 5.1 of the triangular shape, the nose 5 has a second flank 5.3 with a gradient opposite to the vertical direction V. The slope of the first flank 5.2 is less than the slope of the second flank 5.3. This means that the nose 5 along the horizontal direction H initially rises less steeply in the vertical direction V and after reaching the tip 5.1 of the triangular shape counter to the vertical direction V rapidly falls. This advantageously allows easy insertion of the hinge bracket 4, while at the same time holding the cassette 3 securely on the hinge bracket 4. To further simplify the insertion of the hinge bracket 4, it is conceivable that the surface of the nose 5, preferably the entire nose 5 is made of a plastic. In order to be able to use the hinge arrangement 100 both with doors or windows hinged on the left and with doors or windows hinged on the right, the cassette 3 has a further nose 5′ lying opposite the nose 5 in the vertical direction V. If the stop of the tape arrangement 100 is exchanged, then instead of the nose 5, the further nose 5' can engage in a further recess 6' lying opposite the recess 6 in the vertical direction V and hold the hinge bracket 4 in the recording area 9 of the cassette 3. In order to make it easier to slide the hinge bracket 4 into the receiving area 9, the receiving area 9 is dimensioned in the vertical direction V in such a way that the additional nose 5' and the additional recess 6' are spaced apart by a distance. When changing the stop, another threaded hole 8' in the hinge bracket 4 enables the hinge bracket 4 to be screwed to the cassette 3. The other threaded hole 8' is spaced in the vertical direction V by the distance from the threaded hole 8 with which the other Nose 5' is spaced apart from the further recess 6'.

The further lug 5' is also asymmetrically shaped and along the horizontal direction H initially up to the further tip 5.1' of the triangular shape has a further first flank 5.2' with a gradient opposite to the vertical direction V parallel to the hinge axis. In the horizontal direction H after the further tip 5.1', the further nose 5' has a further second flank 5.3' with a slope along the vertical V direction. The slope of the further first flank 5.2' is less than the slope of the further second flank 5.3'.

FIG. 3 shows the belt arrangement 100 shown in FIG. 2 in assembled form. The hinge bracket 4 is pushed into the receiving area 9 . Through the upper transparent point A it is easy to see how the lug 5 engages in the recess 6 . To fix the hinge bracket 4 to the cassette 3, the screw 11 is screwed through the through hole 7 into the threaded hole 8. reference list:
