The ornamental frame is mounted by an anchoring member (6), inaccessible from the outside, which is undetachably attached to the panel. Preferably the ornamental frame is moulded in one piece with the panel. The panel, at least on the outside (8), may comprise a thin plate (9) of deep-drawable material with the ornamental frame formed by a deep-drawn edge region of the plate, the concavity of this region being filled with a cast resin.

Description

The present invention relates to a frame with filling lung according to the preamble of claim 1.

Such frames with filling find Ver use on front doors or balustrades.

For this purpose, the individual frame legs are opened Miter cut and a filler plate before assembling weld the frame legs into corresponding internal ones Longitudinal grooves of the frame legs installed.

Here, optical and / or functional For reasons cutouts provided in the filling, the z. B. as Light opening equipped with glass or for receiving a Mirror or the like. So the clippings are provided with a component that certain An claims z. B. the light permeability.

For visual reasons, then at least on the outside an all-round ornamental frame is provided on the side of the filling, that jumps over the edge of the cutout so far, that the edge of the section is covered.  

Such fillings occur in the area of the outside lying ornament frame a burglar-easing Vulnerability about which a burglar is relatively easy Can provide access.

So z. B. in a known manufacturing process the ornamental frames to the ones that have not yet been cut out Filling cast on. This is done by an intimate bond between the resin and the filling, which however is a violent clear opening by means of the corresponding rear gripping lever cannot prevent.

Once the burglar has the interface between the section of the filling and the z. B. introduced there Glass pane reached, he usually has easy play around to create a passage opening there.

It is therefore an object of the present invention, the be known frame with filling so that under Ver Avoiding additional effort with the usual today Manufacturing process the break-in weakness avoided on the outside ornamental frame and the burglary security is increased.

The invention solves this problem with the features of Claim 1.

The advantage of the invention is that the au external ornament frames together with the filling one practically insoluble unit that forms exclusively under extreme violence can be separated. Only after Separation of the structural unit between the external orna ment frame and filling is the parting line between the filling and the assembly element in the cutout of the filling Lich. Until then, however, a burglar will have to suffer a great deal do exercise work. The effort required for this exceeds by far the usual burglary effort to date. The Ab frightening effect of such frames combined with filling with the anchoring of the external ornamental frame on the  Filling therefore serves an exponential increase in Security against burglary.

Various embodiments are available for the invention games into consideration, in particular the invention in Com combination with cast-on external ornament frame Be attention is to be paid. Essential for this training is an interaction between the adhesive forces of the outside ornamental frame lying on the outside of the filling and the holding forces given by the anchoring. On the In order to successfully break in, any shear force must be used te to overcome the adhesive forces between the outside Ornamental frames and fillings can be increased exponentially as before the destruction of the glued joint first of all the usual significantly more resistant anchoring can be overcome got to.

The ornamental frame is made from one piece and attached the filling is cast on, so it can be added overall resist increased torsion whatever promotes stability.

Another embodiment of the invention provides that the filling, at least on the outside, a thin plat te of deep-drawn material and that the outside ornamental frame through a deep-drawn edge area the plate is formed. For this, the concavity of the Edge area then filled with a casting resin, on which the anchorage is also in place. It arises in this way external ornament frame consisting of a composite material whose strength properties are characterized by a Superposition of the mutual strengths of the be add divided materials.

On the other hand, the practically continuous au external thin plate an additional parting line for the external ornament frames avoided, so that another Opportunity to pry off the ornamental frame falls.  

The formation of the anchor can, for. B. by tie rods take place, the min corresponding anchor abutments in the Orna frame should be cast in.

For this purpose, several individual anchors can be attached to the um Arrange the beginning of the outer ornamental frame and either an independent anchor abutment for each provide for individual anchoring or individual anchor abutments each for groups from neighboring anchorages or continuous anchor abutment for all anchorages.

Individual exemplary embodiments are given for this.

The type of anchoring of the external ornament frame mens can either be done by individual tie rods be provided, which the filling up to the inside break through and there by means of an enlarged contact surface are supported. Another form of anchoring is available especially with fillings that are at least on the outside side have a thin plate, which faces inwards an insulation layer connects. In this case it is suggested gene, the insulation layer in the edge area of the cutout in porridge ten- or in the circumferential direction at least partially and the thin Cut out the plate underneath. Then the is off saved area used for the anchoring of the outside to attach the ornamental frame there. For this, will given examples of leadership.

For the version of the anchorage via individual tie rods it is also proposed the enlarged contact area of individual thrust washers, which are directly on should rest on the inside of the filling and through there each an associated tie rod against the inside of the Filling are kept.

Continuing education provides for groups summarized tie rods by jointly connecting pressure to hold panes against the inside of the door panel. in the in the extreme case, all individual tie rods can be passed through a cohesive print frame together on the inside  Connect the side of the filling to each other around the outside In this way, ornamental frames are fixed all around the filling clog.

For this purpose, the train is also proposed anchor on the inside of the filling with a rear grip bracket to equip that with corresponding rear gripping partners of the pressure plates / the pressure frame supported are. This can be pairings of bolts with end Ver thickened and made of slices with holes that are in a slot that can be gripped by the thickenings Zen.

The combination of pressure washers / pressure frame in connection dung with an inner ornamental frame offers the additional Advantage that the inner ornamental frame has a double function Fulfills. In this case, it serves on the one hand to cover the Partition between filling and z. B. a glass pane in the out cut the filling and at the same time the practically insurmountable anchoring of the external ornamental frame. That knows tere basic principle of the invention, according to which the anchoring of external ornament frame in the area of the insulation layer Filling and the thin outer panel of the filling around is envisaged, also allows a one-piece Ver binding between anchoring and external ornamental frame men to.

The Vari is particularly advantageous in terms of production technology ante, with which external ornamental frame and anchoring are cast together as a unit. Usually a casting resin used here, e.g. B. polyurethane.

If this training is an additional reinforcement cast-in sheet metal, which is through the outside ornamental frame to anchor and from there into the Anchoring extends into it, this offers the additional Advantage that the otherwise considerable shrinkage of the Gießhar zes is kept low during curing. So it was surprising schenderenden found that by pouring reinforcement kungsblechen in the outer ornamental frame of the un  desired shrinkage is practically avoided. It is therefore a particular advantage of this training that when curing of the cast resin, the internal stresses in the adhesive joint between fill and external ornament frame minimized will. For this reason comes the further education endings of the invention with practically completely continuous Anchor abutments in the outer ornamental frame are cast in, special importance. The practical Stress-free production of the external ornament frame mens and the resulting practically tension-free Adhesive joint between the outside ornamental frame and the filling creates additional security against possible break-in attempts che.

Another advantage of the invention is that also Cutouts with rungs can be crossed without the advantage of anchoring arising from the anchoring security would be diminished.

For this purpose it is additionally proposed that To connect the rungs in one piece to the ornamental frame. This can be particularly easy in the case of casting production by Ver appropriate forms.

In addition, this technology allows internal Integrate reinforcement elements into the rungs. Through the intimate connection between reinforcing elements and rungs there is an additional stabilization, so that in particular Cutouts, the clear opening widths of 40 cm x 40 cm or have greater security against creating too provide accessible openings.

It can be taken into account that in the case crossing rungs the reinforcing elements on their cross are mutually released. This is done an additional wedging and stabilization of the intersecting sprouts at their crossing points and thus a white further reduction of the risk of departure. The reinforcement elements te are preferably made of tough metal, e.g. B. V2A.  

Another essential aspect of the invention is based on the fact that in the case of the use of casting resins for the external ornament frame internal reinforcement element elements can be poured. In this way shrinkage in addition to improved safety against prying the profile cross-sections of the outer ornamental frame significantly lessen what additional benefits regarding that offers a perfect fit.

In the following the invention based on execution examples explained in more detail. Show it:

Unless otherwise stated below, the following description always for all figures.

The figures show a frame 1 with filling 2 from which a section 3 has been removed. Usually, such a frame is built together from individual frame spars, which are angularly adapted to one another at the corners via miter cuts and then welded together there to who. On the inside of the individual frame spars a umlau fende groove is formed, in which the filling 2 is inserted. In this way, the filling is kept within the assembled frame spars.

The section 3 serves z. For example, the inclusion of a glass plate, a mirror, od. The like., Referred to as a mounting member 27. For optical reasons, the cut-out 3 is at least surrounded on the outside of the filling 2 by a circumferential ornamental frame 5 , which jumps over the edge 4 of the cut-out in the direction toward the inner region of the cut-out 3 . In this way, the parting line between the cutout 3 and the glass / mirror inserted therein is covered by the external ornamental frame 5 .

It is now essential that the outer ornament frame 5 is attached to the filling 2 by means of an inaccessible covered anchoring 6, which is inaccessible from the outside 8 behind a covered area 7 .

For this purpose, there is a practically unsolvable in nige connection between the outer Or namentrahmen 5 and the filling 2 , so that the circumferential parting line between the edge 4 of the cut and the glass / by violent penetration into the skipping area of the outer ornament frame mens 5 Mirror remains inaccessible.

The anchoring therefore creates a practically indissoluble connection between the outer ornamental frame 5 and filling 2 . This intimate connection can only be overcome by destroying the anchor.

Of particular advantage is an embodiment in which the outer ornamental frame 5 is cast on the outside 8 of the filling 2 , preferably cast in one piece.

In this way, in addition to an adhesive connection between the ornamental frame 5 and the filling 2 , the anchoring 6 is additionally effective, so that the tamper resistance of the ornamental frame 5 is achieved by the need to overcome both the adhesive forces and the forces required to break the anchoring 6 .

In addition, Fig. 2 shows a further development, in which the filling 2 at least on the outside 8 has a thin plate 9 made of thermoformable material. The thin plate is deep-drawn in an edge region of the cutout 3 . In the concavity thus formed, a casting resin 26 can now be introduced, on which the anchor 6 is also to be provided. In the exemplary embodiment shown, the filling 2 is made up of several layers. In addition to the thin outer plate 9 , an insulation layer 17 is provided which is delimited on the inside by a likewise thin plate.

The insulation layer 17 is partially removed in the peripheral area of the cutout 3 . The removed areas are filled with casting resin 26 so that the thin plate 9 is engaged behind. One can now easily imagine that the outer ornamental frame 5 is formed in this way from multilayer composite material, the overall strength of which consists of a combination of the individual strengths of the casting resin 26 and the material of the thin plate 9 .

In addition, FIGS. 3, 7 and 8 show a training in which 5 anchors abutment 11 is / are cast in the outer ornamental frame.

Anchor abutment 11 of this type is formed by material of high strength running at least partially in the circumferential direction (e.g. metal, carbon fiber construction, high-strength plastics), which is enclosed on all sides by the surrounding material of the outer ornament frame 5 . Tie rods 12 , for example, are firmly connected to the anchor abutment 11 and are firmly anchored in the filling 2 .

For this purpose, several individual anchoring stanchions 6 can be arranged on the circumference of the outer ornamental frame 5 and an independent anchor abutment 11 can be provided for each individual anchoring 6 .

This state of affairs is shown schematically in FIG. 4. For this purpose, FIGS . 4 to 6 show top views of the external ornamental frame 5 , which is attached to the filling 2 via individual anchors 6 .

A further development is shown in FIG. 5. Here, several individual anchors 6 are arranged on the circumference of the outer ornament frame 5 and an independent anchor abutment 11 is provided for a group of adjacent anchors 6 .

In a further development of the invention can be provided with the ornamental frame 5 practically completely encircling anchorage 6 (see FIG. 8), in which case either anchor abutments 11 connected in sections are seen before, which are cast into the ornamental frame 5 or their anchor abutments 11 are practical is also completely encircled in the ornamental frame 5 , see Fig. 6. It is easy to imagine that, as shown in dashed lines, the anchor abutment 11 are only provided in sections, while at the same time the anchor 6 Ver almost completely with the ornamental frame running.

In addition, FIGS . 3 and 7 show that the anchoring tion 6 has individual tie rods 12 , which break through the filling 2 to the inside thereof and which are supported there by means of an enlarged contact surface.

For this purpose, the enlarged contact surface according to FIG. 3 can be formed by individual pressure disks 13 . The thrust washers can lie on the inside of the filling 2 directly or with the interposition of sta bilizing flanges and can be held by one or more tie rods 12 against the inside of the filling 2 .

It is therefore also possible to form thrust washers 13 which hold grouped and adjacent tie rods against the inside of the filling. In a further development of this invention, the pressure disks can also be designed as a continuous circumferential pressure frame and then be held together as the only component on the inside of the filling 2 .

Fig. 3 shows an embodiment in which 11 are firmly connected to the anchor abutment screw-in sleeves, which are inserted into corresponding recesses of the filling 2 . In continuation of these recesses, screw holes are provided which end on the inside of the filling 2 . From this side, clamping screws are screwed into the open screw-in ends of the screw sleeves with the interposition of the pressure disks 13 . In this way, the external ornamental frame 5 is held firmly against the filling 2 and anchored there.

A further development of the invention results from the fact that the tie rods 12 are supported on the inside of the filling 2 by means of rear grip holder 14 for corresponding rear grip partners 15 of the pressure plates 13 or the pressure frame. In this context, it should be noted that the pressure frame is only a further development of the pressure washers in that all tie rods are simultaneously comprised of a single component and are pulled to the inside of the filling 2 .

A further advantage is a further training in which according to Fig. 7, the printing frame is part of the inner frame 16 Orna ment. In this inner ornamental frame 16 , with corresponding covering of the ornamental frame material, entry pockets are provided which end in a slot that can be gripped behind. The thickened ends of the tie rods 12 are brought into the area behind the thrust washers through the enlarged entry openings. Then, by moving the inner ornamental frame in the direction of the entry slots, the thickened ends 14 of the tie rods 12 are securely gripped behind in the pocket areas of the entry slots.

Furthermore, FIGS. 1 and 8 show a development in which the filling 2 has a thin plate 9 at least on the outside 8 . An insulating layer 17 adjoins the thin plate 9 on the inside. The insulation layer 17 is at least partially recessed in the edge region 4 of the cutout 3 in the width or circumferential direction in such a way that the thin plate 9 is undercut by the recess. The anchoring 6 is now introduced into the spared zones. The anchoring 6 encompasses the thin plate 9 on the one hand, while on the other hand it is firmly connected to the outer ornament frame 5 . The recess extends to the bottom of the plate 9 . The anchor 6 is glued to the water point with the underside of the thin plate.

For a firm connection, a one-piece design of the anchoring 6 with the external ornament frame 5 is recommended. This can easily be achieved by means of a casting resin for the production of the frame 5 .

Furthermore, Fig. 1 shows an embodiment in which chem the outer ornamental frame 5 and the anchor 6 are cast as a unit together and completely encircled in an annular manner.

In order to further reinforce such a construction, it is additionally proposed according to FIG. 8 to cast an angled reinforcement plate 18 with it. The reinforcing plate 18 extends on the one hand in the circumferential direction of the outside of the ornamental frame 5 and transversely thereto and is initially angled in the direction of the anchoring 6 . Up to the level of the Ver anchor 6 runs the angled area to reverse from there again in the direction of the anchor 6 .

This creates a thin plate 9 U-shaped structure made of cast resin-metal insert Ver composite material, which can only be cracked with simultaneous destruction of both the cast resin component and the reinforcement unit 18 .

It can now be easily imagined that the cutout 3 can be crossed by rungs 19 , 20 from a corresponding size, generally larger than 40 cm × 40 cm (see FIG. 9). For this purpose it is advantageous to form the rungs 19 , 20 in one piece with the external ornament frame 5 . If you want to further increase the security against burglary, elements 19 , 20 inside reinforcing elements 21 , 22 can be integrated into the rungs 19 , 20 . In this way, a break-proof composite material is also created for the rungs. In particular, when the reinforcing elements 21 , 22 are upright in the rungs, and when the reinforcing elements in the crossover region of two rungs 19 , 20 also interlock (see FIG. 9), an additional bond is created in the common area of the notched zones 23 , 24 , which has extremely high resistance to lateral sliding attempts.

In addition to the angled reinforcing plate 18 and any anchor abutments 11 , provision can be made for at least partially integrating internal reinforcing elements 25 into the outer ornamental frame 5 in the longitudinal direction. Such reinforcement elements, in addition to their desired reinforcement property, produce the additional effect of reduced shrinkage. If the outer ornamental frame 5 is made of a casting resin, the shrinkage of the casting resin during curing can be reduced even further by inserting appropriate reinforcing elements 25 .
