Description

The invention relates to a frame element, in particular safety frame, for attachment in a wall opening of a wall, with at least one spacer element, which is arranged in a formed between the frame member and the wall or the wall opening gap.

From the DE 100 28 439 A1 is an arrangement of a frame in a recess of a wall, such as a wall recess, known, in which the frame is connected via a mechanical attachment to the wall. A joint extending between the frame and the wall is filled with a grout material filling it, such as, for example, a foam hardened after insertion. In order to ensure a simple positioning of the frame with good insulation between the frame and the wall, the frame is floatingly supported in the recess of the wall via the mechanical attachment or supported. In this case, the mechanical fastening comprises sliding elements, such as sliding pins or sliding pins, which are fixed in the wall and slidably extend into the openings arranged in the frame, such as bores. However, the mechanical attachment can also be fixed to the frame and slidably extending in the wall arranged in the recesses, such as holes.

Furthermore, it is known in frame elements, which are mounted in a wall opening for the formation of safety frames, insert between these and the wall plate-shaped spacer elements for bridging the gap. Although in many cases a pressure-resistant training of the spacer element created, however, the adaptation of the plates was connected to different gap widths with a lot of work and therefore expensive.

The present invention has for its object to provide a frame member, which provides over the prior art increased burglar resistance, and a method for assembling such a frame member to create.

This object of the invention is solved by the features of claim 1.

The resulting from the features of claim 1 surprising advantage is that by selecting the mass to form the spacer element has these mutually different state forms. In this case, the introduction or attachment of the mass at the predeterminable support points of the frame element in the gap between the wall or the wall opening and the frame element is substantially simplified. After solidification or the transition to the second solid state form thus a hard or pressure-resistant spacer element has been created, which is as far as dimensionally stable in the possible subsequent attachment of the fastener that subsequent deformation and associated relative displacement of the frame member with respect to Wall or wall opening secured prevented. Furthermore, it is advantageous that a wide variety of gap widths can be bridged and even on uneven surfaces a good surface contact between the frame member and the wall or wall opening can be achieved. Due to the dimensional stability and the associated hardness or compressive strength of the spacer element, a solid connection, in particular an additional screw connection, and thus a secure mounting of the frame on the wall or in the wall opening can be achieved. In addition, an even more stable and tear-resistant mounting of the frame member on the wall can be achieved and a central force introduction of the fastener on the spacer element and on the wall can be achieved and thus torsion-free mounting of the frame element on the wall achievable.

It is also advantageous that the mass for forming the spacer element at predeterminable locations or positions on the wall and / or the frame element can be applied and when moving a simple deformation of the mass and associated adaptation to the masonry can be achieved and so different gap widths can be easily and permanently bridged.

A further advantage is an embodiment according to claim 2, since the mass for adapting the spacer element can be adapted to a wide variety of gap widths and, in addition, simple shaping during the displacement process is possible.

It is also conceivable to achieve a massive bridging of the gap, in which the attachment of the fastening element to form a tear-resistant mounting of the frame member, in particular the door frame, is ensured in the wall opening. As a result, even higher compressive forces, starting from the fastening element, can be applied to the frame when fastening the same to the wall and can thus be transferred without warping or distortion-free.

According to another embodiment variant according to claim 3 or 4, a spacer element is provided which bridges the gap distance between the frame member and the wall or the wall opening constant and so always the gap is completely bridged in the region of the spacer element after the displacement and setting of the frame member.

Through the development according to claim 5 it is achieved that the frame element is already held with a predeterminable adhesive or adhesive force in the wall opening on the wall or connected thereto.

Also advantageous is a development according to claim 6, as this can be taken into account economic issues and at predeterminable positions or positions, the support of the frame member is ensured via the spacer element on the wall or wall opening.

In the embodiments according to claims 7 to 9 is advantageous that thereby the support and distance bridging of the gap exactly to pre-definable Positions or positions can be performed and thereby the structural arrangement of arranged on the door leaf components can be taken into account.

Through the development according to claim 10 ensures that an even more stable and pressure-resistant support of the frame on the wall or wall opening can be achieved.

As a result of the construction according to claim 11, a more stable support can be achieved with additional fastening elements aligned obliquely to the wall flight and furthermore a support of both parts of the frame element in its corner region.

Finally, however, an embodiment as described in claims 12 to 14 is possible because it can be used on commercial means, which can be used for bridging the gap of the invention and have sufficient dimensional stability when applying a compressive force by the fasteners, without doing to be deformed yourself.

A method for mounting a frame element with the features of claim 15 is also proposed.

In this method, the fastening system may be a screw.

In an advantageous embodiment of the method, the regions of the gap that are not filled by the spacer element are filled with a mounting foam.

The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and

should be transferred to the new situation in the event of a change of position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

In the Fig. 1 is a door assembly 1 in a wall opening 2 of a wall 3 shown schematically simplified. The door assembly 1 essentially comprises a door frame 4 and a, on door hinges 5 on the door frame 4 pivotally mounted door leaf 6. Furthermore, the door frame 4 comprises at least one chuck board 7 and both sides adjoining trim elements, in the present embodiment, a trim panel 8 and a folding panel. 9 which together enclose or overlap the wall 3 or the masonry approximately in a U-shaped arrangement. In the presentation, a simplified version for the door frame 4 was selected, but this does not limit to this, but all Holzzargenarten and / or wooden sticks, such as block, frame, board, studs, post frames and / or poles , are included in one or more parts in cross section. Instead of the door frame 4 but other frame or frame elements, such as window frames or the like., Are mounted in the wall opening 2, wherein the following description, however, refers only to the support and fixation of the door frame 4 and it is analogous to this embodiment of the invention to transfer to these frames and / or frame parts or elements. These frames and / or frame parts or elements can be used for a wide variety of door types, such as single and / or multi-leaf doors, sliding doors, etc., application.

Furthermore, the door leaf 6 has a simplified illustrated pusher assembly 10 not shown closure means, which cooperates with a arranged in the door frame 4 strike plate 11.

In the door assembly 1 shown here is a so-called security door, the minimum requirements for burglary protection in the ÖNORM B 5338 are regulated. However, doors which are designed to be fire-retardant are also regarded as security doors, the requirements of which being defined as fire-resistant doors in ÖNORM B 3850. Within the scope of this standard with the criteria defined therein, the entire door arrangement 1 can also be referred to as a so-called "tested safety door". Due to the increasing number of burglaries, especially in business premises and apartments, the need for security measures in the door area is increasing. Very often there is no point to install on the existing door leaf 6 additional locks, better locks or security fittings, as this or even the floor or the door frame 4 are too weak. Likewise, it makes no sense to install a new security door leaf in a too weak frame or in a wooden stick. Regardless of the aforementioned ÖNORM - which does not mandatorily require multiple locking, each safety door should have briefly mentioned characteristics below. The door leaf 6 should be resistant to bending or kinking and torsion, in the region of the handle assembly, ie the lock side, has several locks that engage in the door frame 4 and have a stable lock or handle assembly 10. Furthermore, bolts are to be provided which engage in the door frame 4 on the hinge side or in the region of the door hinges 5. Likewise stable fishing or door hinges 5 are to be selected, which are dimensioned according to the door weight. But it is also a security fitting, which is optionally provided with a drilling protection, particularly advantageous. Furthermore, the door frame 4 itself is stable according to form and in addition this is still well anchored to the masonry or the wall 3 or the substructure.

In the FIGS. 2 and 3 is simplified, the door frame 4 is shown, again with the same parts the same reference numerals or component names, as in the previous Fig. 1 , be used.

The door frame 4 shown here in simplified form is designed as a so-called safety frame and has, in addition to the usual Türbändem 5 and the strike plate 11 more known Safety fittings 12, which are indicated in the right vertical part of the door frame 4 simplified by rectangles. These safety fittings 12 cooperate with fixed and / or changeable in their length formed domes, cones or cones, which in turn are arranged in the region of the door leaf 6, but not shown here. These safety fittings 12 have, inter alia, multiple locks and are well known in the art. The door hinges 5 have been shown only schematically simplified and can be freely selected according to the known prior art in terms of security issues.

Furthermore, in the area of the door hinges 5, the additional safety fittings 12 and the striker plate 11 are simplified, in each case a spacer element 13 is shown, which will be shown and described in more detail in the following figures. The one or more spacers 13 are selectively over the longitudinal extent of the door frame in a, in the Fig. 3 arranged schematically, between the door frame 4 and the wall opening 2 and the wall 3 formed gap 14 is arranged. In addition, it would also be possible to arrange the spacer element 13 continuously over the longitudinal extent of the door frame 4 in the gap 14. For reasons of economy, however, the regional or punctual arrangement is preferred.

The here in the FIGS. 2 and 3 The selected division or arrangement of the door hinges 5 and the additional safety fittings 12 has been chosen only as an example for a variety of possible design variants, this being freely selectable depending on the commercially available fittings.

The spacer element 13 is formed from a mass which has a first deformable state form and a second, different, respectively fixed, state form. In the first deformable state form, the mass to form the spacer element 13 is still pasty or doughy and can additionally build up an adhesive force or adhesion force to within the gap 14 on the one hand to the wall opening 2 or wall 3 facing surface of the door frame 4 and on the other hand to stick to the wall 3 or the masonry or the like fixed. When mounting the door frame 4, the mass can be applied partially and / or continuously on the surface of the door frame 4 facing the wall 3 and / or on the wall 3 or wall opening 2 and subsequently at least a portion of the door frame 4 - for example, the feedboard 7 with the folding panel 9 - inserted into the wall opening 2, positioned and aligned accordingly. This process is also referred to as displacement of the door frame 4. The mass automatically bridges the remaining or formed gap 14 between the door frame 4 and the wall opening 2 or the wall 3 due to their limited flow properties. Then it would also be independent of this possible, if previously no mass up to the formation of the spacer element 13 has been introduced or to introduce the mass in the gap 14 and to bridge the gap 14 at least partially over the longitudinal extent of the entire door frame 4. A filling of the entire gap 14 over its cross section is also possible in special applications.

Subsequently, it is waited for a dependent of the mass used solidification or curing time until the mass has passed into its second, solid state form and bridged gap in this 14 distance. It is advantageous if, starting from the first state form, the mass passes into the second state form forming the spacer element 13 without shrinkage or else with low shrinkage. This ensures a safe bridging of different distances or clearances of the gap 14. In addition, it is advantageous if the mass or the material for forming the spacer element 13 also builds up a sufficient adhesive force and thus adhesion between the frame element to be supported and the wall opening 2 or wall 3. If this is sufficient, the additional mechanical fastening means can be dispensed with.

During the transition of the mass starting from the first state form into the second state form, in which the spacer element 13 is formed, this mass is allowed to swell only slightly or not at all, in order to leave the frame element already pre-positioned in the wall opening 2 unchanged in its position.

Furthermore, it is essential that the spacer element 13 in its second state form sufficient dimensional stability, such as sufficient hardness or compressive strength, which is so high that in the later described in more detail possible fastening operation no relative displacement of the frame member with respect to the wall 3 and Wall opening 2 takes place. This is because at least one additional attachment between the door frame 4 or in it or arranged thereon in the case designed as a safety door frames 4 Reinforcement or holding elements and the wall 3 can be attached. This is usually done by retrofitting a hole in the wall 3 and by screwing with various means. In this case, the distance-maintaining property of the spacer element 13 is important in order not to cause distortion of the door frame 4, as was the case with otherwise conventionally used mounting foams. The detailed description of the solution according to the invention is given in the following figures.

As a material or mass for forming the spacer 13 may e.g. a reaction adhesive find use. This may be formed from a two component adhesive, e.g. may be formed on an epoxy resin with a hardener or on an acrylate resin basis with a hardener. Various manufacturers distribute such reaction adhesives for fastening connecting elements, such as Anchor rods, internally threaded sleeves, reinforcing bars, profiles, etc. in concrete, masonry of solid and natural stone. In this case, the reaction adhesive can be stored spatially separated from each other in a cartridge and be brought together for the intended use by a mixing element, whereby the reaction is started.

In the 4 and 5 is a possible, possibly independent training or arrangement of the spacer element 13 in the gap 14 between the door frame 4 and the wall 3 and the wall opening 2 shown. In this case, the same reference numerals or component designations for the same parts as in the preceding Fig. 1 to 3 used. Likewise, to avoid unnecessary repetition, the description in the previous Fig. 1 to 3 referred or referred.

In this embodiment shown here, an installation situation of the door frame 4 is selected, in which this surrounds a already arranged in the wall opening 2 and connected to the wall 3 steel frame 15 or overlaps. The door frame 4 is shown simplified and includes the feedboard 7 and the trim and folding panel 8, 9. Furthermore, the strike plate 11 by means of an additional mounting plate 16 to form the security frame with the door frame 4, in particular the feedboard 7, respectively. That in the Fig. 2 indicated schematically and here in the Fig. 4 Spacer element 13 shown in detail fills or bridges the gap 14 between the door frame 4, in particular the corner region between the rebate cover 9 and the feed board 7.

The assembly of the frame member may be such that a frame part in the wall opening 2 of the wall 3 prepositioned and then introduced at the pre-definable points the mass to form the spacer element 13 in the gap 14. After the curing process described above or the transition to the second state form, the completion of the frame element takes place. It is also possible to fill the remaining gap 14 with a conventionally used and known mounting foam.

Another possibility of mounting the door frame 4 would be that the mass to form the spacer element 13 before the displacement of the door frame 4 at least partially mounted on the door frame 4 and / or partially applied to the wall opening 2 at predeterminable positions, it then the door frame 4 is displaced and in this aligned position of the door frame 4, the mass solidifies or hardens to form the spacer element 13.

It would also be possible, however, to completely set the entire frame element, in particular the door frame 4, and to align or position it accordingly in the wall opening 2 and through specially provided openings in the frame element, the mass for forming the spacer element 13 through it into the gap 24 contribute. This can be done for example by means of a tube which is inserted through the opening into the gap 14 and then introduced thereto by this the mass.

Due to the fact that the mass for forming the spacer element 13 is pasty or doughy in its first state form, an automatic bridging or filling of the gap 14 takes place between the door frame 4 and the wall 3 or the steel frame 15. After hardening or solidification the mass and formation of the spacer element 13, bridged this gap in its second state form the gap 14 distance. Subsequent to solidification or curing, the additional arrangement of a fastener 17 shown in simplified form, which in the present embodiment, the mounting plate 16 passes through for secure and tear-resistant mounting of the strike plate 11 and projects in a known manner in the wall 3 and there over a variety, not closer shown holding means, such as dowels, gluing, etc., is held. It is possible that the solidified or hardened spacer element 13 is penetrated by the fastening element 17. This can be done for example by simple drilling, due to the through the fastener 17 on the mounting plate 16 and subsequently applied to the door frame 4 compressive force and the pressure-resistant or stable formation of the spacer element 13 a deformation or displacement of the door frame 4 relative to the wall 3 and the wall opening 2 is prevented.

In the Fig. 5 an identical installation situation of the door frame 4 in the wall opening 2 at the opposite of the strike plate 11 portion of the door frame 4 is shown. Again, in turn, the steel frame 15 is arranged in the wall opening 2 in a simplified manner, the spacer element 13 being arranged in the region of the door hinge 5 in the gap 14 arranged between the wall opening 2 and the steel frame 15. Likewise, the door hinge 5, in particular its hinge axis, in turn, the fastening element 17 associated with the formation of the safety frame. On the detailed representation of fitting parts, such as door hinges 5, additional security fittings 12, etc., was omitted for the sake of clarity.

For additional, mutual alignment of the door frame 4, in particular of the chuck board 7, with respect to the wall opening 2 and the wall 3, it is possible to introduce an additional mounting means, such as a mounting adhesive or mounting foam in the gap not specified here, wherein the mounting means has been shown simplified with a wavy line.

In the 6 and 7 is a similar door frame, as in the 4 and 5 represented, in contrast, the wall opening 2 in the wall 3 is formed irregularly, for example by a wall opening or the like. Likewise, the same reference numerals or component names are used here for the same parts, as in the preceding Fig. 1 to 5 used. In order to avoid unnecessary repetition, the detailed description in the preceding is preceded Fig. 1 to 5 referred or referred.

At the in Fig. 6 illustrated installation situation of the door frame 4, which is shown in the region of the striking plate 11, in turn, the spacer element 13 is shown in its gap-bridging, cured position in the gap 14. As a result of the previously described pressure-resistant design of the spacer element 13 in its second, fixed state shape in combination with the first deformable state shape, the complete, permanent bridging becomes the gap 14 between the door frame 4 and the wall opening 2 and the wall 3 guaranteed. Likewise, the additional fastening element 17 in the region of the mounting plate 16 in conjunction with the strike plate 11 is shown again to form the safety frame. This fastener 17 is preferably attached later after reaching the second state form in a known manner. An additional stabilization of the door frame 4 relative to the wall 3 can in turn be achieved by the previously described assembly adhesive or mounting foam.

In the Fig. 7 a larger gap 14 between the door frame 4 and the wall opening 2 and the wall 3 bridged by the spacer 13 distance distancing and achieved by the additional fastener 17, the tear-resistant mounting of the door frame 4 on the wall 3.

In all the embodiments described above in detail, the spacer element 13 is arranged in the corner region of the door frame 4, namely the folding panel 9 and the chopping board 7. This is because the fastening element 17 is mounted in an oblique position to the wall 3 in the end face of the wall opening 2. Finally, it should be pointed out that the door frame 4 described here does not necessarily have to be, but that spacer elements 13 can also act in the case of window frames or other frame or frame elements that can be arranged in a wall opening 2 and should also be covered by the teaching according to the invention ,

The embodiments show possible embodiments of the door assembly 1, in particular the door frame 4, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but also various combinations of the individual embodiments are possible with each other and this variation possibility due to Teaching for technical action by objective invention in the skill of those working in this technical field is the expert. There are therefore also all possible embodiments, which are possible by combinations of individual details of the illustrated and described embodiment, the scope of protection.

For the sake of order, it should finally be pointed out that for a better understanding of the construction of the door arrangement 1, in particular the door frame 4, these or their components partially displayed off-scale and / or enlarged and / or reduced.

The problem underlying the independent inventive solutions can be taken from the description.

Above all, the individual in the Fig. 1 . 2 . 3 . 4 . 5 ; 6, 7 shown embodiments form the subject of independent solutions according to the invention. The relevant objects and solutions according to the invention can be found in the detailed descriptions of these figures.
