In carrying out the manufacturing method according to the EP 2 612 979 A2 as well as the EP 2 455 575 A2 It has been found that with previous methods of providing lock pockets it is difficult to ensure the desired planarity in all cases. One possible source of error is the entry of heat during welding. On the other hand, it has been found that a firm connection between lock pocket and reinforcing plate during the manufacturing process and in particular during pressing and gluing can likewise lead to the outer jacket surface on the broad side and / or the front side deviating from the desired planarity.
Accordingly, in the case of the previous door production method with lock pockets, the problem was that the previous solution of welding the lock pocket to a reinforcing flat steel could not achieve the required flatness of the reinforcement.

According to a particularly preferred embodiment, a clip technique is provided which joins the lock pocket to itself. Especially Preferably then the lock pocket is clamped by means of a screw-on or the like with the fastening screw of the castle. The mounting tab is preferably bent during assembly.

One of the main advantages is that there is no heat input into the module and thus no heat distortion is recorded.

Another advantage is the floating storage of the lock pocket, which thus allows a possibility of tolerance compensation in the production of the door leaf. Only with screwing in the lock the lock pocket is clamped.

In the FIGS. 1 to 8 different views of a door leaf 10 are shown, which are formed from outer jacket plates 12, a filling 14 therein and a lock assembly 16 for receiving a mortise lock.

As casing sheets 12, a box plate 18 and a cover plate 20 are provided in the illustrated embodiment.

The box plate 18 encloses a cavity 22 which is filled with the filling 14. The cover plate 20 is profiled at the edge region in such a way that it encompasses an edge region of the box plate 18 and forms a thick fold 24.

The filling 14 is glued to the box plate 18 and the cover plate 20 and provided in the region of a lock with a recess 26 in which the lock assembly 16 is housed.

The shrouds 12 and the filling 14 form a door leaf body 28 which is constructed and manufactured as described in more detail in the EP 2 455 575 A2 or the EP 2 612 979 A2 described and shown.

In the area of the door hinges 30, a reinforcing angle 31 made of thicker steel is provided on the door leaf body 28.

In the area of the lock a lock reinforcement 32 is provided on the box plate 18, which is formed of a reinforcing flat steel 34 and in the FIGS. 27 and 28 is shown individually.

Optionally, a reinforcement angle 36 for a door closer on the hinge opposite side and / or a reinforcement angle 38 for a door closer on the hinge side are provided on the upper hinge-side corner region.

The filling 14 is formed for example of a one-piece (or multi-part) mineral fiber plate 40, which is designed according to a desired door function - for example, fire protection.

To form a part of the respective door hinges 30, a screwable wing part 42 is fastened with a thread-forming screw 44 with a countersunk head.

Further, a securing bolt 46 is attached to a fixed to the box plate 18 reinforcing flat steel 50 for the securing bolt with the interposition of a toothed disc 48.

The in the FIGS. 9 to 12 Lock assembly 16 shown in more detail has the lock reinforcement 32 formed by the reinforcing flat steel 34, a lock pocket 52, and insulating panels 54. The insulating plates 54 are attached to the lock pocket 52, for example by means of adhesive bonds.

The lock pocket 52 serves to receive a mortise lock 56, which is in particular in Fig. 7 is shown. As a mortise lock 56 in particular a lock according to DIN 18250 is provided. The mortise 56 engages with mounting plates in the FIGS. 27 and 28 lock recess 60 shown in detail in the reinforcing flat steel 34 and is fastened there by means of Schraubbefestigern 58. The screw fasteners 58 also serve to fasten the lock pocket 52 to the reinforcing flat steel 34 and thus the lock reinforcement 32nd

The lock reinforcement 32 is fixed to the box panel 18, for example by welding, forming part of the door panel body 28.

On the other hand, the lock pocket 52 is free of sweat and free of heat input, in particular fastened only to the lock reinforcement 32 via the screw fasteners 58. As a screw fastener 58 serve, for example, countersunk sheet metal screws.

The following is based on the representation of the FIGS. 9 to 12 the lock assembly 16 explained in more detail.

As already explained above, the lock assembly 16 has the lock reinforcement 32, the lock pocket 52 and insulating plates 54.

On the side of the box plate 18 (Gegenbandseite) an insulating plate 54, for example, a thickness of 15 mm provided, a same insulating plate 54 is provided on the side of the cover plate 20, also with a thickness of 15 mm, it is between the cover plate 20 and the one Insulating plate 54 is still a thinner insulating, for example, 9.5 mm thick, used.

For attachment of the insulating plates 54 with the lock pocket and each other bonding surfaces 62 are provided, as shown in the Fig. 11 are shown in more detail. At these bonding surfaces 62, the insulating plates 54 are bonded together and with the lock pocket 52. The insulating plate 54 serves to isolate the Lock area for the purpose of the desired door leaf function, in particular fire protection function.

In the illustrations, a door leaf 10 is drawn to the right according to DIN, a door leaf according to DIN left results from a corresponding mirror image.

The lock pocket 52 will be described below with reference to FIGS. 15 to 26 , which illustrate the lock pocket 52 individually, explained in more detail.

The lock pocket 52 is formed from a sheet material 64 in the form of a steel sheet 66, which in Fig. 25 is shown completed.

The steel sheet 66 is in the in Fig. 25 shown shape with two openings 68 for door handle, two openings 70 for lock cylinder, two Anschraublaschen 72, two Klippsverbindungsöffnungen 74 and notches 76 and then made to the with the dotted lines in Fig. 25 indicated fold lines 78 bent to the sheet material 64 in the in Fig. 16 to 24 to bring illustrated shape. As a result, corresponding edge regions 80 of the steel sheet 66, which form overlapping wall regions 82 of the lock pocket 52, overlap at the lock pocket 52.

In addition, in the region of the clip connection opening 74, the respective other edge region 80 is notched in order to form a clip tab 84, which is clipped into the clip connection opening 74 in order to form a clip connection 86.

As can be seen from the detailed representations in Fig. 21 . 23 and 24 this clip connection 86 results, the clip connection 86 braces a bending apart of the larger lock pocket wall regions 88 provided with the openings 68, 70 for the door handle and the lock cylinder. However, these lock pocket wall portions 88 can be moved toward each other due to the clip connection 86. The lock pocket wall portions 88 are further with a recess 90 ins Interior of the lock pocket 52 provided out, which receive the mortise 56 between them.

The Anschraublaschen 72 are provided with through holes 92 which are formed as in the thickness direction of the lock pocket 52 extending slots 94. The elongated holes 94 and the passage openings 92 are dimensioned such that they are larger than screw-in openings 96 for the screw fasteners 58 on the lock reinforcement 32.

In the manufacture of the door leaf 10, the procedure is as follows.

First, the box plate 18 is provided and provided with the reinforcements 32 to 38 and 50. The filling 14 is inserted into the cavity 22 of the box plate 18, providing a bond between the box plate 18 and the filling 14.

The lock pocket 52 is in the from the 15 to 26 resulting manner, wherein one of the Anschraublaschen 72 is not yet bent, as shown in Fig. 13 is shown in more detail. On the lock pocket wall portions 88, the insulating plates 54 are adhered to the bonding surfaces 62. This combination of lock pocket 52 and insulating plates 54 is inserted into the lock reinforcement 32 and into the recess 26 of the filling 14. The lock pocket 52 is stored floating; It is not yet connected to the lock reinforcement 32. The insulating plates 54 are glued to the box plate 18.

Subsequently, the adhesive is applied to the remaining free surface of the filling 14 and the cover plate-side insulating 54. Then the cover plate 20 is pushed onto the box plate 18, as shown in more detail in the EP 24 55 575 A2 and / or the EP 2 612 979 A2 is shown and shown.

The curing of the adhesive takes place under extensive pressing of printing plates on the outer sides of the jacket plates 12th

Due to the floating mounting of the lock pocket 52 and the clip connection 86, tolerances in the area of the lock can be compensated, so that a large degree of flatness can be achieved even in the area of the lock.

The remaining Anschraublasche 72 is only after inserting the lock pocket 52 in the insertion through hole 98 of the reinforcing flat steel 34 folded so that the Einschraublaschen 72 engage in separate Anschraublaschen-wells 100 on the outside of the reinforcing flat steel 34. The final attachment of the lock pocket 52 to the reinforcing flat steel 34 takes place only when inserting the mortise 56 and screwing the mortise 56 by means of Schraubbefestigern 58, which engage through the through holes 92 of the Anschraublaschen 72 into the screw-in 96 of the reinforcing flat steel 34 into it.
