Description

Technical area

The invention relates to an assembly aid for a door or a window with concealed bands, each band has a hingedly connected via two bearing elements with the door frame hinge tab, which is receivable in a corresponding receptacle in a wing part on the door leaf or door profile.

State of the art

In door hinges or door hinges, respectively, a frame part and a wing part are hinged together. In the case of visible door hinges, the frame part usually has a pivot pin on which a corresponding counterpart is placed on the wing part. The joint is thus formed only when hanging the door. It has long been known that the hanging of door or window sash brings some difficulties, since the often heavy and bulky wing must be very precisely maneuvered to the appropriate locations on the frame so that the door hinge can connect accordingly. In the case of the above-described visible door hinges, there are in the prior art some auxiliary devices which are usually plugged as a kind of guide device near the pivot pin on the frame part and force the wing part into position by inserting appropriate guide sections.

For concealed door hinges, there is now the additional problem that the rotatable hinge of the door hinge is already formed in the frame part by a hinge tab is rotatably mounted therein. This hinge flap must be maneuvered when mounting the wing in corresponding recesses in the wing part and secured therein. There is thus added the additional difficulty when hanging the wing, that the hingedly movable hinge tabs often do not point in the same direction with multiple hinges or move during hooking, which complicates the work additional.

Brief description of the invention

The invention now aims to eliminate this problem and a To provide mounting aid, which also significantly simplifies the hanging of door or window sash with concealed door hinges and fixes the corresponding hinge tabs in predefined positions. The mounting aid should be used in a variety of different hinges. The production should be cost-effective and the application should be straightforward.

This object is achieved by the present invention in that the mounting aid comprises a substantially U-shaped bracket, wherein the two legs are formed as clamping portions which are inserted into the space between hinge tabs and the respective bearing elements to the hinge tab in its position to fix to the bearing elements, and wherein the two legs connecting portion has a handle portion. The curvatures of the hinge tabs and their thickness can vary greatly between the different door hinges depending on the size and weight of the door or window sash and the desired opening angle. However, the height of the individual hinge tabs and the gap between hinge tabs and bearing elements are constant over many models, which is why the inventive device is universally applicable. By inserting the mounting aid all door hinges of a door or window sash can be fixed in the same position, which then remains the same during the entire Einhängvorgangs.

According to an advantageous embodiment of the invention, it is provided that the two legs are tapered wedge-shaped at their free ends for ease of insertion into the space between hinge tabs and the respective bearing elements. Since the gap width between bearing elements and hinge tabs can have different tolerances, it is advantageous to form the free ends of the legs of the mounting aid tapered wedge-shaped. As a result, the insertion is simplified in any case and the mounting aid can be securely wedged.

It is an additional advantageous feature that the clamping portions at their side faces facing away from each other transversely to the longitudinal extent of the legs extending ribs or grooves have, which increase the clamping action. Due to the surface enlargement, the friction on the clamping portion can be effectively increased.

It is also a feature of the present invention that in addition to the U-shaped bracket, an angle bar is provided with a central portion and angled edge portions, wherein the edge portions are angled within the same plane to different sides and at different angles from the central portion. An angled edge portion of the angle bar can be stopped before inserting the U-shaped bracket on the door frame, whereby the hinge flap can be particularly easily adjusted to the central portion of the angle bar. An angled edge portion can be arranged for example at an angle of 90 ° and the other edge portion at an angle of 45 °. As a result, all hinge flaps of the wing can be very precisely adjusted to the same angle and then fixed by inserting the U-shaped bracket.

Finally, it is an additional feature of the invention that the free ends of the angle bar as a tool tip, for example as a screwdriver, tool bit, clamp or the like, are formed. The angle bar can have additional functions. Thus, for example, one end may be shaped to engage in a corresponding recess in the wing part, for example, to release a blocking element for the hinge plate or to bring in the locked position. Furthermore, at the other end of the angle bar, a corresponding end section may be formed, which engages in recesses of an insertable securing element, whereby this securing element can be maneuvered to its intended position after hanging the door or window sash.

Description of the embodiments

The in Fig. 1 shown frame part of a concealed door hinge according to the prior art has two bearing elements 1, between which a hinge plate 3 is hinged.

In order to fix the hinge tabs 3 in its relative position to the bearing elements 1, the U-shaped bracket 5 of the assembly aid according to the invention according to the Fig. 2 used. For this purpose, the U-shaped bracket 5 is taken on the handle portion 9 at the connecting portion 8 and the two legs 6 inserted into the respective gaps between the bearing elements 1 and the hinge plate 3.

In Fig. 3 the concealed belt with arranged U-shaped bracket 5 is shown mounted on a door frame 2. The hinge tab 3 is in the assembled state while in a corresponding recess in a wing part (not shown), which is mounted on the door leaf or door profile 4.

Fig. 4 shows the U-shaped bracket 5 in detail. It comprises two legs 6, which are connected to each other by means of a connecting portion 8. At the connecting portion 8, a handle portion 9 is formed. At the two legs 6 are each clamping portions 7. The free ends of the legs 6 have wedge-shaped tapers 10 for easier insertion. The clamping portions 7 also have on their side faces facing away from each other ribs 11 and corresponding grooves, which increase the clamping action in the inserted state.

In Fig. 5 an angle bar 12 is shown in a possible embodiment. The rod has a central portion 13, on which edge portions 14,15 are arranged at both ends angled. The first edge portion 14 is angled at a 90 ° angle from the central portion 13. The second edge portion 15 is angled at an angle of 45 °.

The free ends 16,17 of the edge portions 14,15 are formed in the example shown as tool tips. The first free end 16 of the first edge portion has a geometry of a tool bit, which serves for releasing or tightening a locking element on the wing part. The final fixing of the door or window sash therefore requires no additional tools. The second free end 17 of the second edge portion 15 is formed to engage in a corresponding recess of a securing element, which is then held by means of clamping action at the free end 15. By means of the angle bar 12 then this fuse element can be easily inserted into the intended position in the wing part.

To adjust the hinge tabs of a door or a window of the respective desired edge portion of the door frame can be stopped accordingly to align the hinge tab 3 at the correct angle to the central portion 13 of the angle bar 12. In Fig. 6 is shown how the angle bar 12 is stopped with the second edge portion 15 on the door frame 2 and the hinge plate 3 is aligned parallel to the middle portion 13 at a 45 ° angle accordingly. Subsequently, the hinge tab 3 is fixed by inserting the U-shaped bracket 5 in this position.
