Description

Technical area

The invention relates to an arrangement comprising a hinge for concealed mounting for a door or a window, wherein the hinge has a hinge flap which is connected to the door frame in an articulated manner via two bearing elements and which can be received in a corresponding receptacle in a wing part on the door leaf or door profile, and wherein the arrangement additionally has a separate mounting aid.

State of the art

With door hinges, a frame part and a sash part are connected to one another in a hinged manner. With visible door hinges, the frame part usually has a pivot pin onto which a corresponding counterpart on the sash part is placed. The hinge is therefore only formed when the door is hung. It has long been known that hanging door or window leaves entails some difficulties, as the often heavy and bulky sash must be maneuvered very precisely to the appropriate places on the frame so that the door hinge can connect accordingly. With the visible door hinges described above, there are a number of auxiliary devices in the state of the art for this, which are usually attached to the frame part as a type of guide device near the pivot pin and which use corresponding guide sections to force the sash part into the correct position when inserted.

Concealed hinges have the additional problem that the hinge's pivoting joint is already formed in the frame part by a hinge tab that is pivotally mounted in it. When the sash is hung, this hinge tab must be maneuvered into the corresponding recesses in the sash part and secured there. When hanging the sash, there is therefore the additional difficulty that the hinge tabs often do not move in the same direction when there are several hinges. or move during the hanging process, which makes the work even more difficult. EP3034734A1 reveals such a bond.

The FR 2962777 A1 shows a complicated multi-part gripper that can be used in the hinge area of a door and with which an axle pin can be inserted or removed. The device is very complex and is not used to insert a hinge tab but rather an axle pin, where the specific angular position is irrelevant, unlike the position of a hinge tab.

The EN 102013108085 B3 shows an assembly aid for fixing a hinge flap to prevent it from pivoting when the door leaf is inserted. The assembly aid is sleeve-shaped with corresponding recesses and is placed on the hinge's axis of rotation from above. It is only possible to fix the hinge flap in a single position and not at any angle. Furthermore, this device cannot be used on concealed door hinges because it is placed on the hinge axis.

Brief description of the invention

The invention now aims to eliminate this problem and to create a hinge with an assembly aid that also makes it much easier to hang door or window sashes on concealed door hinges and fixes the corresponding hinge flaps in predefined positions. The assembly aid should be usable with a large number of different door hinges. It should be inexpensive to manufacture and uncomplicated to use.

This object is achieved by the present invention in that the assembly aid comprises a substantially U-shaped monolithic clamp, wherein the two legs are designed as clamping sections that can be inserted into the space between the hinge tab and the respective bearing elements in order to fix the hinge tab in its position relative to the bearing elements, and wherein the section connecting the two legs has a handle section. The The curvature of the hinges 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 hinges and the gap between the hinges and the bearing elements are constant across many models, which is why the device according to the invention can be used universally. By using the assembly aid, all door hinges on a door or window sash can be fixed in the same position, which then remains the same throughout the entire hanging process.

According to an advantageous embodiment of the invention, the two legs of the assembly aid are tapered in a wedge shape at their free ends to facilitate insertion into the gap between the hinge tabs and the respective bearing elements. Since the gap width between the bearing elements and hinge tabs can have different tolerances, it is advantageous to design the free ends of the legs of the assembly aid to be tapered in a wedge shape. This makes insertion easier in any case and the assembly aid can be securely wedged.

An additional advantageous feature is that the clamping sections of the assembly aid have ribs or grooves on their opposite side surfaces that run transversely to the longitudinal extension of the legs, which increase the clamping effect. The friction on the clamping section can be effectively increased by increasing the surface area.

It is also a preferred feature that, in addition to the U-shaped bracket, an angle bar with a central section and angled edge sections is provided as an assembly aid, wherein the edge sections are angled from the central section to different sides and at different angles within the same plane. An angled edge section of the angle bar can be held against the door frame before inserting the U-shaped bracket, whereby the hinge flap can be adjusted particularly easily to the central section of the angle bar. An angled For example, one edge section can be arranged at an angle of 90° and the other edge section at an angle of 45°. This means that all hinge tabs on the sash can be set very precisely to the same angle and then fixed in place by inserting the U-shaped bracket.

Finally, it is an additional preferred feature that the free ends of the angle bar are designed as a tool tip, for example as a screwdriver, tool bit, clamp or the like. The angle bar can have additional functions. For example, one end can be shaped to engage in a corresponding recess in the sash part in order to release a locking element for the hinge flap or to bring it into the locking position. A corresponding end section can also be shaped at the other end of the angle bar, which engages in recesses of an insertable securing element, whereby this securing element can be maneuvered to its intended position after the door or window sash has been hung.

The Fig.1 The frame part of a concealed door hinge shown has two bearing elements 1, between which a hinge flap 3 is held in an articulated manner.

In order to fix the hinge plate 3 in its relative position to the bearing elements 1, the U-shaped clamp 5 of the assembly aid according to the invention is used in accordance with the Fig.2 To do this, the U-shaped clamp 5 is taken at the handle section 9 on the connecting section 8 and the two legs 6 are inserted into the respective gaps between the bearing elements 1 and the hinge flap 3.

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

Fig.4 shows the U-shaped clamp 5 in detail. It comprises two legs 6, which are connected to one another by means of a connecting section 8. A handle section 9 is formed on the connecting section 8. Clamping sections 7 are located on each of the two legs 6. The free ends of the legs 6 have wedge-shaped tapers 10 for easier insertion. The clamping sections 7 also have ribs 11 or corresponding grooves on their side surfaces facing away from one another, which increase the clamping effect when inserted.

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

The free ends 16,17 of the edge sections 14,15 are shaped as tool tips in the example shown. The first free end 16 of the first edge section has a geometry of a tool bit, which is used to loosen or tighten a locking element on the wing part. Consequently, no additional tool is required to finally fix the door or window wing. The second free end 17 of the second edge section 15 is shaped to fit into a corresponding recess of a securing element, which is then held by means of a clamping effect at the free end 15. This securing element can then be easily inserted into the intended position in the sash part by means of the angle rod 12.

To adjust the hinge flaps of a door or window, the respective desired edge section on the door frame can be held accordingly in order to align the hinge flap 3 at the correct angle to the middle section 13 of the angle bar 12. In Fig.6 It is shown how the angle bar 12 is held with the second edge section 15 on the door frame 2 and the hinge flap 3 is aligned parallel to the middle section 13 at a 45° angle. The hinge flap 3 is then fixed in this position by inserting the U-shaped bracket 5.
