Description

The invention relates to a method for producing a door leaf according to the preamble of the appended claim 1 and a producible with this method door leaf according to the preamble of the appended claim 14. Such a method and such a door leaf are the FR 25 81 122 A3 removable.

Door leaves of the form explained in more detail below have been manufactured and distributed by Hörmann KG Freisen and Hörmann KG Brandis for a long time. In the known door leaves of the type in question, a filling made of styrofoam, mineral wool, honeycomb-shaped cardboard layers or the like insulating material formed on the outside of the filling with coated or uncoated metal sheets is glued. The thus composed of composite door leaf receives its rigid structure without inner frame, namely mainly on the sheet metal outer shell or its outer skin of sheet metal, while the filler material for thermal and / or sound insulation is used. Such door leaves are due to their relatively light weight quite easy to handle and inexpensive to manufacture. They are therefore particularly well suited as interior doors. However, the previously known doors have been able to oppose a burglary attempt only little resistance. This is due in particular to the fact that the filling material used hitherto can offer little support to a lock exposed to a burglary attempt. In addition, it was due to the soft consistency of the filling materials with the previously known production method for such doors only possible to use simple locks with a simple latch.

An example of such a door leaf with a simple lock, which is provided only with a simple latch and the usual case, is also from the DE 19 86 750 U1 removable. To produce this known door leaf, two sheet metal plates are joined in a box-like manner in the door leaf form and completely foamed up inside with a foam-like, porous solid plastic. This is to form a Lock pocket a prefabricated or subsequently prepared insert made of wood or other material firmly foamed.

From the above-mentioned FR 25 81 122 A3 On the other hand, a door leaf of a completely different kind is known, namely one with a supporting metal frame, two cross struts and metal covers. To provide a multiple locking device, the lock-side vertical spar of the metal frame in the lock area is U-shaped and accommodates the multiple locking device in this U-shaped profile.

It is therefore an object of the invention to provide a method of the type mentioned for producing a door leaf in such a way that a light and therefore easy to handle, and yet burglaries a high resistance opposing door leaf is inexpensive to produce.

This object is achieved by a method of manufacturing a door leaf having the steps of appended claim 1. A door leaf producible by such a method is the subject of the appended claim 14.

According to the invention, for the first time, a frameless door leaf with a hard supporting outer jacket and soft filling material can be provided with a multiple locking device. For this purpose, the invention proposes to provide a receiving device for the multiple locking device as a filling insert within the outer shell in addition to the filling material in the lock side end face.

The invention is based on the recognition that it is almost impossible to preform the outer sheath as usual and provided with preformed filling materials so that a suitable receptacle for offered on the market or otherwise prefabricated multiple locking devices can be formed. The invention therefore takes a different, surprisingly simple way of first producing a door leaf blank having a reinforced lock-side end area without punched holes or prefabricated openings, and only then cutting and grooving the openings and grooves into the door leaf blank by multi-stage milling.

In this case, the door leaf blank is produced by full-surface gluing in a sandwich structure, then milled in several stages: In the manufacture of the door leaf blank on the lock side a receiving block is provided in the form of a continuous bar, then receiving grooves and / or receiving pockets for the multiple locking device are introduced. This strip or this at least one receiving block are introduced in addition to the filling material as a filling insert.

Advantageous embodiments of the invention are the subject of the dependent claims.

When manufacturing the door leaf blank is preferably used as a bar or receiving block in which the recording is introduced, preferably a block or a block bar on the basis of wood materials, in particular or with solid, barrier or Fumierschichtholz, and more especially from or with Abachi. Wood is inexpensive, easy to handle and has sufficient strength to provide a strong support for the multiple locking device. A particularly high stability is achieved in a further preferred embodiment characterized in that the receiving block or the receiving bar is dimensioned such that it fills as a filling insert the entire closing side end portion of the stimulus area. For solid bonding of the individual materials forming the door leaf blank, it is further preferred that the filling material and the filling insert - ie the receiving block formed, for example, as a strip-shaped lock wood - be included the outer jacket glued over the entire surface. In particular, the receiving block without intermediate layer of filling material is glued directly to the outer jacket, ie, in particular to a metal sheet, on both sides and in the closing-side end area of the stimulus. Preferably, a polyurethane-based adhesive specially designed for bonding wood and metal is used.

Now it can happen that in a break-in attempt not (only) on the lock itself, but (also) is manipulated on the door hinges. Therefore, not only the lock, but also the door hinges should be resilient. In an advantageous embodiment of the invention, it is therefore proposed that, when the door leaf blank is produced as an additional filling insert in the band-side end face region, at least one strip-side block strip in which the door hinges can be anchored is inserted into the outer jacket, d. H. arranged, for example, between two metal sheets forming the outer jacket, and firmly connected to the outer jacket. In order to use a same door leaf blank for both right- and left-pivoting doors, it is proposed according to a further advantageous embodiment of the invention that the door leaf blank is formed mirror-symmetrically to the vertical longitudinal center line, in particular the castle-side reinforcing filling insert - the receiving block or the bar for the multiple locking device - and the band-side reinforcing filling insert - the block strip for the door bands - are designed and arranged according to each other.

The door leaf blank can be produced provided with a fold, in which case the receiving block and possibly the band-side block strip are executed rebated, so that each provided in the end face areas fold is reinforced. In concrete embodiment, a sheet metal forming or covering the first door leaf broadside, which can also be referred to as a door leaf sight side, can be guided around the horizontal end face areas - which can also be labeled as horizontal door leaf narrow sides. It is then preferably provided in the folding area with a step-like final training for covering the fold and glued to the lock-side receiving block and possibly with the block bar. The second, the fold having door leaf broadside is then formed or covered by a second metal sheet, which is glued on the second broad side with the receiving block and possibly with the block bar. In the respective fold regions, the second metal sheet is bent over the fold and the step-like end formation of the first metal sheet engaging thereon and firmly connected to the first metal sheet. This can be z. B. done by gluing or embossing or any other known metal compound. In such a trained on the vertical end face areas with fold door leaf blank then the receptacles for the multi-locking device in the unrebated area, d. H. introduced the remaining adjacent to the fold area of the lock side end face.

The introduction of the recording in the receiving block is carried out according to the invention by multi-stage milling. This includes according to the invention in a first Frührufe an exposure of the at least one receiving block and in that portion or those portions of the lock-side end face in which the at least one receptacle is to be introduced. For this purpose, the outer jacket is milled. In this first, only the milling of the substantially metal outer sheath comprehensive Frasstufe can then be used simply a metal cutter. The first milling stage is preferably computer- or CNC-controlled such that in fact only that portion or those portions are exposed, which are then actually filled by a corresponding cover strip, a cuff or the like of the multiple locking device, so that in the finished state of the door leaf the inside recording block is not visible from the outside.

For other door leaf types are already standardized multi-locking devices on the market. These usually include a main lock, which is provided with an upper and a lower spaced from the main lock engagement means in the form of one or more bars, bolts or hooks with housing. The bolt, bolt or hook of these engagement means is then actuated by a push rod or the like driving element by means of the main lock. In the later visible area these multiple locking devices are usually provided with a covering metal strip with circular cuffs, with which the bolt, latch or hook housing is attached to the main lock housing. From this bar then stand the individual housing in one direction, whereby the push rod or the other driving element is guided on this side along the covering metal strip. In order to accommodate such standard available multiple locking devices in a safe and cost-effective manner in the door panel according to the invention is proposed according to a further advantageous embodiment of the invention that during or for making the receptacle at least one receiving groove for the push rod or other driving element and / or for the cover strip or the same connection element is milled for connecting a lock-spaced engagement with the lock in the receiving block, which is then preferably a second cutting stage of the multi-stage milling. It is further preferred that during or for making the receptacle each have a receiving pocket for the lock and for each spaced from the castle engagement -. B. for the bolt, bolt or hook housing - is milled into the receiving block, which is preferably carried out in a third milling stage of multi-stage milling. Of course you can but also first in a second Frasstufe the receiving pockets and then in a third Frasstufe the receiving groove or grooves are milled.

In order that the lock, which is usually encompassed by the multiple locking device and thus arranged depending on the arrangement of the receptacle in the door leaf, via appropriate openings with a door handle and a lock cylinder or the like locking actuator can be actuated, it is proposed according to a further advantageous embodiment of the invention In addition to the discharge of the recording openings in the broad or visible side of the door leaf blank for a door handle and / or for a lock actuator, such as lock cylinder, code button or the like, are machined. This is preferably also done by milling and more preferably in a fourth milling stage of the multi-stage milling process.

In this case, B _T denotes the width of the receiving pockets 42 to 44.

The door panel 80 according to the third embodiment is shown in FIG Fig. 10 version shown instead of the safety pin 36, a third central door hinge element 82. As in Fig. 14 indicated, is a door leaf blank (not explicitly shown), in which the milling provided for the receptacle 35 and the door hinge elements 37, 38, 82 are not yet introduced, executed symmetrically to the longitudinal center plane or longitudinal center line 83. The Fig. 16 illustrates the formation of Hauptschlossausfräsung, which forms the second receiving pocket 43, the Fig. 17 illustrates the cutout in the region of the push rods 56, 57, which forms the second receiving groove 41, and the Fig. 18 illustrates the cutout of the upper and lower lock case, which forms the first and third receiving pocket 42, 44.

The production of the door leaves 10, 70, 80 is effected in that first of the door leaf blank by gluing the steel sheets 19, 21 with the inner filling, d. H. with the tube chipboard 22, the mineral wool mat 81 or optionally a Styrofoam plate or cardboard honeycomb (not shown) and the two wooden strips 25, 26 in the vertical end face regions 23, 24 is produced. The bonding takes place over the entire surface, wherein in particular in the region of the wooden strips 25, 26, a metal-wood adhesive is used based on PU. Together with the upper and lower metal shutters 31, 32, a door leaf blank is formed completely without punching or milling, but the fold 14 is already provided as shown. Following the production of the door leaf blank, the actual finishing is done by milling.

This milling is done in a CNC-controlled milling device such as in the FIGS. 21-23 is shown.

The milling device 85 comprises a conveyor system 86 for the delivery of the door leaf blank and the delivery of the finished door leaf 10, 70, 80, a via a guide device 87 on a machine bed 88 in three axes - horizontally along, horizontally across, vertically - computer-controlled movable three-axis NC - Processing unit 89, a milling unit 90 for the door handle opening 66 and the lock cylinder opening 67, a retaining means 91 for holding the door panel 10, 70, 80 during the milling operation, a side alignment device 92 for aligning the door leaf 10, 70, 80 for the milling operation and a guide ruler 93 for the lock-side end face 12.

The NC processing unit 89 has a first milling unit 94 for sheet metal milling, a second milling aggregate 95 for milling out the receiving pockets 42-44, a third milling aggregate 96 for milling out the first receiving groove 40 and a fourth milling aggregate 97 for milling out the second receiving groove 41, as well as a measuring probe 98 on.

The manufacturing process for finishing the door leaf blank is as follows:

1. 1. inlet of the door leaf blank in the multi-axis milling device 85;
2. 2. Aligning and centering the door leaf blank;
3. 3. Horizontal milling of the metal sheet 19 with the first milling unit 94;
4. 4. Multi-stage horizontal milling for the production of the receptacle 35 in the lock-side wooden strip 25, wherein the receiving pockets 42 to 44 are milled by means of the second milling unit 95 in one of the milling stages, in another of the milling stages by means of the third milling unit 96, the first receiving groove 40 milled and in the remaining milling stage by means of the fourth milling unit 97, the second receiving groove 41 is milled - these Horizontalfräsungsstufen are monitored by the probe 98;
5. 5. Vertical milling of sheet metal and wood combined for the pusher hole / Schlosslochfräsung means of Fräsaggregats 90;
6. 6. Spout of the finished door leaf 10, 70 or 80 from the milling device 85 or milling station 85 and cleaning the door and finally
7. 7. Final assembly, wherein the respective multi-locking device 58,59, 63 is mounted in the receptacle 35.

In the course of the milling process, therefore, a distinction is made between a pure sheet metal milling and a wood milling. This is particularly important in the horizontal milling, in which a particularly large amount of sheet metal must be milled. Due to the different consistency of sheet metal and wood, other milling tools are also needed here. In addition, with the extent of the necessary milling in the horizontal milling, the wood of the lock-side wooden strip 25 could be damaged or catch fire due to overheating. The usual with metal milling liquid cooling could not be used because of a possible damage to the wood in a combined sheet metal / wood milling.
In the case of vertical milling, only a small sheet thickness and only a small amount of sheet metal is to be milled. Therefore, a combined sheet metal / wood milling is possible here.

All features and steps of the door panels described here and the manufacturing method described here can be arbitrarily combined with each other and interchanged, unless this can obviously be excluded.

Door leaves 10,70,80 of the type described have already been classified with the filling with tube chipboard 22 or mineral wool 81 according to the new ENV standard 1627 (classification ET 1 / WK 2) as a security door.
