Description

The invention relates to a door or window casement made of wood, with a casement spar, which is provided in a closure area adjacent to a frame spar outside and inside with a locking reinforcement plate, which are screwed together.

Such wooden frames are widely used. Since the material wood is comparatively flexible and can also be destroyed or splintered and removed with comparatively simple tools due to its fibrous structure, a break-in in wooden door or window frames due to violent destruction is relatively easy compared to frames made of metal or plastic . Locking and locking points are made accessible and actable so that the window or door can be opened.

From US-A-4 763 499 a wing frame with the features mentioned is known, the wing frame spar is clasped in a U-shape in the closure area. The locking reinforcement plates formed by this clasp are each secured above and below the lock cylinder by L-shaped reinforcing bars and screwed together and with these bars. The screw connection is accessible from the outside.

The invention has for its object to improve a wooden door or window frame so that their security against burglary is significantly increased.

The above-mentioned object is achieved in that a wing overlap projects from a face of the wing frame spar, which covers a gap to the frame spar, which is covered by the locking reinforcement plate almost to the wing face, and in that the two locking reinforcement plates are screwed together from the inside of the door.

The locking reinforcement plate prevents the sash from being effectively splintered, particularly in its frame rollover area, so that the locking means usually present there are not accessible. In particular, the metal locking reinforcement plate prevents violent penetration of a burglary tool in connection with a metal stiffening profile. As a result, the locking area of the wing is effectively secured.

In order not to be able to forcibly spread a wooden door or window wing in the fishing area, a wooden door or window frame is designed in such a way that a spar of a wooden door or window wing in the fishing area is provided on both sides with a reinforcement plate, which is joined together from the inside of the wing are screwed here, the frame being designed in particular so that a frame overlap projecting from a face of the casement spar covers a gap to the frame spar, which is covered by the one armoring plate up to the face of the casement spar such that the second armoring plate extends to the face of the sash frame spar and that the screw connection of the rebar plates on the outside of the sash is inoperable.

Conventional burglary tools are therefore not able to act on the wing in such a way that it splinters in the area of the hinges and can thus be forced apart from the frame. The cover by the fishing rebar plates takes place flush with the wooden edges of the adjacent end face of the frame, so that even the violent penetration of a burglary tool into a gap between the sash and frame is made considerably more difficult.

The frame can advantageously be developed so that one of the fishing rebar plates is provided with a one-piece bearing eye for a fishing bolt.

Another particularly advantageous embodiment is when two screw-in rods are connected to the fishing reinforcement plate, each of which engages at one end of a fishing bolt. As a result of the mechanically firm connection of the fishing bolt to a fishing reinforcement plate, which in turn can be connected to the wing with sufficient security in any way, it is impossible to separate a wing-side fishing bolt without considerable effort. In addition, two screw-in rods attack the fishing bolt, which in turn can be securely anchored accordingly. As a result, the fishing area of a wooden frame can practically not be destroyed by force.

In order to significantly increase the security against burglary of a door or window frame made of wood, the frame is designed in such a way that a metal stiffening profile is arranged over the entire length of the spar on the front face of the frame spar, which is flush with an edge with the spar area adjacent to the frame flap and has all the necessary fitting engagement recesses.

Of importance for the invention is a metal stiffening profile which extends over the entire length of the spar and which covers the end face of the frame facing the casement. In the wood area covered by the reinforcement profile, burglary tools matched to the material wood cannot be used successfully. The screwdrivers and crowbars conventionally used as burglary tools are not able to deform a correctly designed metal stiffening profile in such a way that locking or locking points are accessible and become actable. In addition, the stiffening profile present over the entire length of the spar ensures that all the necessary fitting engagement recesses are present in this stiffening profile. In the case of a large number of such locking or bolting points, breaking into it would be particularly tedious and not very promising. Burglary security is increased accordingly. In addition, the stiffening profile is flush with the spar surface adjacent to the rollover, so that manipulations on the wooden edge adjacent to the rollover are not possible. As a result, a simple splintering of the wood or a simple pressing of a side cover strip of a frame frame of a door is impossible. Another advantage of the door or window frame design described above is that the metal stiffening profile can also be retrofitted to existing frames. The necessary changes to the wooden frame are easily possible with conventional tools and the stiffening profile can be easily adapted to the given dimensions.

Of particular advantage is an embodiment of the frame such that the metal stiffening profile engages with a flat mounting strip in a slot of the frame spar and is fastened there. The mounting strip of the stiffening profile enables improved attachment to the frame spar. In particular, concealed fastening is possible, which is also a safety aspect. The slot of the frame spar can be made to the extent necessary on existing frame spars, so that retrofitting even older door or window frames is possible.

The frame can be designed such that the mounting strip is arranged at an angle to the stiffening profile and engages on the hinge and / or closure side in the frame spar of a window frame. The angular arrangement of the mounting bar to the stiffening profile enables the mounting bar to be installed parallel to the frame level or the associated deep engagement in the wooden frame. There is one Particularly good fastening option for the mounting strip that is integral with the stiffening profile. A violent removal of the stiffening profile with simple means is impossible. The reinforcement described above is particularly suitable for the hinge and / or for the closure side of a window frame, in which the required engagement depths are readily available even for longer or wider installation strips.

A mounting strip arranged at an angle to the stiffening profile can also be used to fasten other components. So it is useful to design the frame so that a threaded rod for a window is screwed into the mounting bar of the stiffening profile. This results in a problem-free and secure attachment of the threaded rods, which protects the window sash against the violent pulling out of the hinges holding it.

In order to make the metal stiffening profile with the mounting strip attached to it particularly suitable for wooden door frames, the frame is designed so that the mounting strip forms a one-piece reinforcement strip with a reinforcement profile designed as a flat strip and into a lining board of the hinge and / or closure-side frame spar intervenes. The mounting strip and the stiffening profile are thus arranged in one plane, namely across the frame plane. In the lining board of the frame spar, the slot required for the mounting bar can be easily produced, in which the mounting bar is fastened, for example by concealed screwing.

The frame is developed in such a way that a support strip is attached at an angle to the stiffening profile and is connected on the hinge and / or closure side to the back of a side cover strip of the frame spar. The support strip arranged at an angle to the stiffening profile forms an integral unit with the stiffening profile. The support strip stiffens the wooden frame, particularly in the area of the side cover strip, and is able to support it. The side cover strip and the lining board of the frame spar of a door frame is thus joined together in a particularly stable manner. The support strip also covers or protects the joint between the lining board and the masonry.

The support bar can be used to attach other components to it. It is particularly advantageous if a threaded rod for a door is screwed into the support strip of the stiffening profile. As a result of the metal design of the support bar, which is integral with the reinforcement profile, there are high pull-out forces for the threaded rods and thus a correspondingly high level of security against the door leaf being forced apart by force from the frame.

The violent spreading of a door leaf is a frequently encountered break-in method, so that it is advantageous to design the frame in such a way that a threaded rod for a door is screwed into a securing angle of the masonry and / or into a reinforcement block arranged between it and the lining board. With these means it can be achieved that the violent spreading of the door leaf is practically impossible.

If a stiffening profile is equipped with a support strip, it is advantageous to design the frame so that a fitting engagement recess for a lock bolt, for a lock latch, for fitting locking bolts or for release locking bolts from the frame overlap are arranged in front of the support strip of the stiffening profile. This then results in comparatively narrow stiffening profiles in the area of the side cover strip, which nevertheless guarantee the required safety.

In the area of a wing's hinges, care must be taken to ensure that the wing cannot be unhooked. As a result, the frame is expediently designed in such a way that a safety catch bolt is attached to a roller tape sleeve of the window or door leaf, or to a reinforcement strip parallel to the stiffening profile of the end face of the window or door leaf. One in terms of components simple design is the roll band sleeve designed as a structural unit with safety catch bolts. However, it requires a correspondingly precise adjustment or a comparatively precise stop of the roller band sleeve on the wing, as well as of the metal stiffening profile on the frame spar, which has an engagement opening for a safety catch bolt. It can therefore be advantageous, particularly when retrofitting a wooden frame, that the safety catch bolt is attached to a reinforcement bar parallel to the stiffening profile on the end face of the window or door leaf.

In order to be able to subsequently attach the side cover strips to the support strips of the stiffening profile of a door leaf in a simple manner, the frame is designed in such a way that the support strip of the stiffening profile is provided with undercut recesses for hooks on side cover strips or with press-fit recesses from fastening projections of the side cover strips. As a result, there are concealed fastenings that firmly connect the side cover strips to the support strip of the stiffening profile without the need for a screw connection. The assembly is accordingly made easier, the safety aspects not being neglected.

The representations of Figures 1 to 3 relate to a section of a vertical wooden frame for a door. The frame spar is designated 11 and serves to clad the masonry 27. The frame spar 11 essentially consists of a lining board 20 and two side cover strips 23 to be assembled therewith, which cover the joint 41 between the lining board 20 and the masonry 27.

A window frame spar 10 is adjacent to the frame spar 11, a portion of which is shown in FIG. 3 of a fishing area. All details of the profile design for the mounting of a door leaf or a window pane are omitted. However, it can be seen that the sash frame spar 10 has a face 12 facing the frame spar 11, from which projects a frame flap 13 which covers the gap 64 between the face 10 'and the adjacent face 12 of the frame spar 11.

The fastening of the lining board 20 to the masonry 27 takes place in a conventional manner by means of stable fastening, e.g. with a screw-in anchor. Corresponding to the distance between two facing feed boards 20 of a door trim, a slot 41 remains between the back of a feed board 20 and the masonry 27, which is bridged with a spacer block, not shown, for aligning the feed board 20.

The fastening of the side cover strips 23 not adjacent to the casement frame, the upper right one in FIGS in a conventional manner, wherein it has been shown that a tongue and groove like positive assembly is provided between this side cover strip 23 and a narrow edge of the lining board 20.

The frame spar 11 or its end face 12, which is essentially formed by the lining board 20, is provided with a metal stiffening profile 14 that extends over the entire length of the spar. According to FIG. 2, this profile 14 covers both the end face 12 in the area of the lining board 20 and the edge area 12 'of the side cover strip 23. The cover is such that an edge 15 of this stiffening profile 14 according to FIG. 2 lies flush with the spar surface 16 adjacent to the frame flap 13, that is to say with the outer surface of the side cover strip 23.

It is also important that the stiffening profile 14 has all the necessary fitting engagement recesses 17. In FIG. 1, such a recess 17 shows a hole for a safety catch bolt 30, which is part of a wing fitting part.

With the metal stiffening profile 14, a flat mounting strip 18 arranged in the same plane is integrally connected, which engages in a slot 19 of the frame spar 11. The mounting strip 18 is fastened in the slot 19, specifically with the aid of fastening screws 42 which are screwed into a lining board 20 through bores 43 in the mounting strip 18. The installation of such a one-piece reinforcement bar consisting of a mounting bar and stiffening profile can take place both on the hinge side, as was shown in FIGS. 1 to 3, and on the locking side, see e.g. Fig. 4.

Furthermore, a support strip 21 is connected to the stiffening profile 14, which is attached at a right angle. This support strip 21 has holes 44 through which fastening screws 45 are inserted, with which a side cover strip 23 of the frame spar 11 is fastened.

From Figures 1 to 3 it can still be seen that a threaded rod 25 is fixed to the frame member 11, which has a pin 25 'for receiving a roller band sleeve 31. The parts 25, 31 form a swivel joint for the casement. The threaded rod 25 is fixed by screwing a threaded pin 25 ″ into a reinforcing block 28, which is arranged in the gap 41 between the lining board 20 and the masonry 27 and is fastened to the rear of the lining board 20 with screws 28 ′.

1 shows a securing bracket 26 which is fixed to the masonry with fastening screws 46. In the illustration in FIG. 1, the securing bracket 26 is used to fasten the structural unit consisting of the stiffening profile 14 and mounting strip 18 to the masonry 27 by means of a fastening screw 47 which is screwed into a bore 48 in the securing bracket 26. In this way, the window frame spar 11 is also firmly connected to the masonry 27 by means of a metal screw connection, it being understood that a plurality of securing angles can be present over the length of the spar (not shown overall).

4 shows the cross-section of the fastening of the stiffening profile 14 or the mounting strip 18 with the aid of the securing angle 26. The attachment of the side cover strip 23 to the support strip 21 with screw connections 52 can also be seen.

3 shows that the roller band sleeve 31 is fastened to the end face 10 'of the casement frame spar 10 with fastening screws 49, a stabilizing tab 50 penetrating the material of the spar 10. The tab of the roll-band sleeve 31 resting on the end face 10 'carries the projecting safety catch bolt 30, which cooperates with the fitting engagement recess 17 already mentioned. Since the bolt 30 is cylindrical or frustoconical, the recess 17 is designed as a correspondingly dimensioned hole.

The wing spar 10 in FIG. 4 schematically shows a lock case 53 in which, for example, a latch bolt lock is installed. The lock bolt 29 of this lock is shown in dashed lines and engages through an unspecified fitting engagement recess in a recess of the side cover strip 23, not shown.

The lock housed in the lock case 53 can be actuated, for example, with a lock cylinder, the actuation axis of which has been designated 54. This lock cylinder, not shown, is covered on one side of the door leaf by a rosette 55 and on the other side of the door leaf by a locking reinforcement plate 40. Both reinforcement parts are screwed together, from the inside of the door. The locking reinforcement plate 40 protrudes with a cover arm 40 'up to the frame flap 13 and covers it at the height of the lock. The distance between the closure reinforcement plate 40 and the stiffening profile 14 or its edge 15 is almost completely filled by the width of the flap 13, so that a break-in at this point is significantly hindered. According to FIG. 13, actuation fittings can be attached to the cover arm 40 ', for example a push button or a pawl, for the fastening of which fastening holes 57 or a square opening 58 are provided.

5 shows the hinge side of the door frame, the stiffening profile 14 of which is designed and fixed in the same way as in FIG. 5 shows a reinforcing block 28 which fills the slot 41 between the lining board 20 and the masonry 27 and serves to fix a screw-in rod 25. According to the length of the reinforcing block 28 shown in FIG. 5, the screw engagement of the threaded rod 25 is long and the pull-out force is disproportionately greater than if the rod were merely screwed into the support bar 21.

FIGS. 6, 7 each show a schematic configuration of the stiffening profile 14 with an associated mounting strip 18 and an associated support strip 21 Installation of the threaded rod 25 is to be understood in such a way that it is fixed according to FIG. 6 through an opening in the masonry 27, for example in a dowel attached there. The hinge 25 can also be screwed into the securing bracket 26. In contrast, Figure 7 shows that the threaded rod 25 is screwed vertically to the support bar 21 in this and its protruding end protrudes into the gap 41 between the lining board 20 and the masonry 27.

Furthermore, it is shown in FIGS. 6, 7 that a safety catch bolt 30 is attached to a reinforcement bar 32, which in turn is fixed on the end face 10 'of the sash frame spar 10 with a fastening screw 59.

The fishing area of the wing shown in FIGS. 6, 7 is provided on both sides with a fishing reinforcement plate 33, 34. The angled armoring plate 34 protrudes over the flap 13 or up to the end face 10 'of the wing and protects accordingly. The opposite armoring plate 33 also protrudes from the edge of the spar 10 or up to the end face 10 '. Both protect these edges accordingly. For this purpose, they are connected to one another by fastening screws 60. The mounting screws 60 are arranged so that they can not be operated from the outside of the door. If the hinge side of the door wing were the outside of the door, the screwing would have to be done the other way round, that is to say the heads of the screws 60 would have to be arranged in the hinge reinforcement plate 33. The same applies to the embodiments of Fig. 4,5.

Fig. 14, 15 show the fishing rebar plate 34 with further details. It can be seen in particular that the fishing rebar plate 34 has a bearing eye 34 'for a fishing pin 35 which projects on both sides of the bearing eye 34'. Accordingly, two screw-in rods 25 are attached, each of which can be attached according to FIGS. 6 and / or 7. 7 shows, in contrast, that the fishing rebar plate 34 does not necessarily have to serve to support the wing, but that a fishing pin 35 also in a conventional manner the frame spar 10 of the wing can be screwed in order to serve the mounting of a threaded rod 25 with a bolt.

1 to 5 indicate that the support strip 21 is screwed to the associated side cover strip 23 of the frame spar 14. This requires a corresponding pre-assembly of this side cover strip 23, the associated stiffening profile 14 and the lining board 20. After the fastening of the lining board 20 to the masonry 27, the screwing points in question are no longer accessible. FIGS. 8 to 10 therefore show configurations with which the side cover strip 23 can also be attached to the masonry 27 even after the lining board 20 has been fastened. According to FIG. 8, a hook 27 is firmly connected to the side cover strip 23 and can engage in an undercut recess 36 in the side cover strip 23. The undercut recess 36 is formed for example by a vertical groove which is covered in its lower part by a cover plate 36 '. This cover plate 36 'is engaged behind by the hook 37 so that the side cover strip 23 is fixed. According to FIG. 9, the side cover strip 23 is provided with an impact piece 61, which is arranged completely in the side cover strip 23 for jamming, but has two fastening projections 39 which protrude in the direction of the support strip 21. The support bar 21 in turn has corresponding press-fit recesses 38 into which the fastening projections 39 can be driven so that they are stuck therein and thus hold the side cover strips 23. The same also applies to the embodiment of FIG. 10, in which the side cover strips 23 are held with a fastening projection 39 designed as a simple cylindrical dowel, each of which forms a press-fit connection with the two parts to be connected to one another. The sectional representation of FIG. 9a that is valid for FIGS. 9, 10 shows the peg-like configuration of all fastening projections 39.

A window frame is shown in FIGS. The frame spars 11 form a closed frame together with cross bars, not shown, just as the wing frame spars 10 with cross bars, not shown, form one form closed casement. According to the hinge side shown in FIG. 12, this sash frame is connected to the frame via at least two swivel joints 62, a screw-in hinge 24 forming the part of a swivel joint 62 on the frame side and a roller band sleeve 31 forming the part of the sash frame side. The roller band sleeve 31 is otherwise designed in the same way as that formed in FIG. Its safety catch bolt 30 engages in a not-specified recess in a stiffening profile 14. Its edge 15 lies flush with the adjacent spar surface 16. A mounting bar 18 is attached to the stiffening profile 14 at a right angle and engages in a corresponding slot in the frame spar 11, which is not shown in detail. With this mounting strip 18, the stiffening profile 14 is fastened on the hinge side in accordance with FIG. 12, as was indicated in FIG. 11 by specifying a screwing point 63. It can also be seen from FIG. 12 that the threaded rod 24 is screwed into the mounting strip 18. Fig. 11 shows that a lock bolt 29 of the wing lock 53 engages in the stiffening profile 14.
