Description

Insulation insert for a profile formed frame

The present invention relates to an insulation insert for a frame, in particular sheet frame, formed by a first frame profile and a second frame profile.

In similar frames formed by frame profiles, in particular for windows, doors and the like, the frame profiles are usually connected by insulating bridges. Since the frame profiles are usually made of metal, in particular aluminum, the insulating bridges used for the connection are made of a material of low thermal conductivity, in particular of certain plastics, in order to improve the thermal insulation behavior of Frame construction Due to the low thermal conductivity of plastics used in insulating bridges, an undesired heat transmission can be effectively minimized by a similar arrangement - in winter the profile directed to the inner side of the building in the direction of the profile directed to the outside air cold and in summer correspondingly in reverse - at least as far as heat conduction is concerned. An unwanted heat exchange can be partially offset due to thermal radiation, while, for example, other bridges are fixed in the insulating bridges that extend essentially parallel to the direction of development of the frame profiles and are provided of a layer that reflects thermal radiation. Furthermore, it is known to fill the intermediate space formed by the frame profiles and the insulating bridges with a foamy mass or the like for the reduction of an unwanted heat transmission by convection.

However, the current solutions are unsatisfactory, particularly later, if a multiplicity of possible profile variants, profile wings, as well as profile widths should be used. When very long profiles must be used, that is, profiles with a great distance from the insulating bridges to each other, there is for example the problem that the additional bridges, provided each time on the insulating bridges and also provided with a reflective layer are they must extend in case of increasing profile, in order to be able to effectively counteract heat transmission by convection and / or thermal radiation. Since in particular the insulating bridges that are used for the connection of the frame profiles are prefabricated on a large scale and should be used for different profile wingspan, in case of a variation in the profile span the need to manufacture or store a multiplicity of different insulating bridges.

If foam is additionally used to prevent convection, then the need for material of this filler foam with increasing wingspan increases considerably.

Furthermore, in a similar solution in which the intermediate space is filled with foam, it is not possible to provide the frame profiles subsequently with a colored coating, since the foam used for filling the intermediate space would deteriorate due to the high temperatures necessary during a coating process of similar color.

On the basis of the problem statement described, the present invention aimed at perfecting the means used for suppressing unwanted heat transmission by convection, but also by thermal radiation, so that in particular in case of variable wingspan of the profile With at least constant thermal properties, universal insulating bridges can be used to connect the frame profiles. Furthermore, an objective of the invention is to use the smallest thermal insulating material both in the case of a variation in the size of the profile as well as in the width of the profile, without essentially worsening the thermal properties. In addition, simple shortening of the profile width or frame width is desired.

The objective is solved according to the invention by means of an isolation insert according to claim 1.

The objective is solved in particular by means of an isolation insert according to the invention for the frame formed by a first frame profile and a second frame profile connected to the first frame profile by means of two insulating bridges, because the isolation insert according to the invention it is composed of at least a first wall and a second wall that runs essentially perpendicular to the at least one first wall, a locking means being configured in at least one of the at least one first walls in a first final region, the design being designed blocking means for, during insertion of the isolation insert according to the invention into an intermediate space formed by the first frame profile, the second frame profile and the insulating bridges, be fixed in an antagonistic blocking means configured in the first profile of frame, and extending in the inserted state the at least one first wall of the insulation insert according to the invention is particularly perpendicular to the profile development of the first frame profile in the region of the antagonist blocking medium.

The solution according to the invention has a whole series of advantages over the previous conventional solution. This considerably reduces, on the one hand, the need for material and also the amount of work and therefore the costs incurred with respect to a foam filling process. In addition, it is possible to configure the insulation insert according to the invention in a single size for different profile wings and variable profile widths, that is, to configure it unitarily for different profile wings and profile widths. Since the insulation insert according to the

The invention is only fixed in a frame profile, great variability occurs and the isolation insert according to the invention can be used equally and with a similarly good effect for different profile wings and profile widths. Another advantage is that the insulation insert according to the invention can also be used for difficult profile shapes, such as corner profiles.

Since the insulation insert according to the invention is configured by at least a first wall and a second wall, which extends essentially perpendicularly to the at least a first wall, in particular it is possible to use similar insulating bridges (i.e., in particular with additional bridges configured of the same length) and an insulating insert according to the similar invention for different profile wings. Since the second wall of the insulation insert according to the invention runs in the same way essentially parallel to the direction of development of the first frame profile, such as the additional bridges of the insulating bridges protruding in the intermediate space, in case of different wingspan In profile, an overlap zone is also produced between this second wall and the additional bridges, so that an unwanted heat transport between the frame profiles can be effectively reduced by convection.

Advantageous extensions of the invention are specified in the dependent claims.

It is then provided, for example, that the insulation insert according to the invention has at least two first walls, where the at least two first walls and the second wall of the insulation insert, together with the first frame profile delimit at least one cavity in the inserted state of the isolation insert. By means of the at least one similar cavity embedded in the intermediate space it is possible to further reduce unwanted convection.

Furthermore, in the case of at least one such embedded cavity it can be provided that a stop means is configured in the first frame profile, with which at least one of the at least two first walls of the insulation insert is partially in contact. . This is particularly advantageous then when only on one of the at least first walls a blocking means is configured, which meshes with a corresponding antagonistic blocking means in the first frame profile. By providing a stop means configured in the first frame profile and since the other wall, not generally provided with a locking means, of the at least two first walls is at least partially in contact with this stop means , a widely sealed closure of the at least one cavity formed and embedded in the intermediate space is produced, so that an effective decrease in heat transmission by convection is guaranteed. A similar stop means, instead of for example another antagonist blocking element in addition to the antagonist blocking means provided for the other of the at least two first walls, also has the advantage that the low manufacturing tolerances, in particular for The insulation insert according to the invention does not negatively impair the accuracy of adjustment of the insulation insert in the sense that the heat transfer by convention is no longer sufficiently diminished.

With the use of this effect, it is also possible to configure the insulation insert flexibly, so that in the inserted state there is a tightly sealed closure of the at least one configured cavity. This is particularly advantageous then when at least one of the at least two first walls of the insulation insert is in contact with a stop means. By appropriate sizing, a flexible configured insulation insert can then be used by holding onto the antagonist locking element and the stop means conditioned by the return forces, so that in addition to the widely desired tight seal of the at least one configured cavity is guaranteed a secure seat, that is, a safe maintenance of the position of the insulation insert in the inserted state. Of course in this context it is also possible to essentially configure similar, in the case of a similar clamping principle, the antagonist blocking means and the stop means, for example, by respectively a curved projection in the first frame profile, so that the blocking means and the stop means together ensure, in the case of a similar clamping solution, the maintenance of the position of the insulation insert in the intermediate space.

Furthermore, it is provided that the second wall of the insulation insert is disposed in a second final region of the at least one first wall opposite the first final region. In this way it is ensured in particular that in case of a variation of the profile width, that is, in case of a variation in the length of the insulating bridges, projections that are not harmful to the at least one first wall are not present. beyond the second wall, which could be disadvantageous in case of a possible necessary shortening of the profile width or width of the foot.

Especially advantageously, it is provided that the insulation insert is symmetrically configured along an axis of symmetry that runs parallel to the at least one first wall. By means of a similar symmetrical form, it is guaranteed in particular that an insertion of the isolation insert cannot be carried out the other way around by mistake in the intermediate space. In particular in this regard it is advantageous to configure the blocking element so that it can be in contact with both an antagonist blocking element and also with an appropriate stop means. Therefore, in general, an equally symmetrical cross-sectional shape of the blocking element is offered.

Furthermore, it is advantageously provided that the second wall extends beyond a connection area with the at least one first wall. In other words, the second wall is expected to extend beyond a region in the

which is connected to the at least one first wall, each time in the direction of the insulating bridges. In particular when exactly two first walls and a second wall are provided, then an insulation insert is produced whose cross-sectional shape is similar to the shape of a small Greek π. In addition to the reduced convection by the at least one configured and embedded cavity, an overlap with other bridges eventually fixed to the insulating bridges is further produced, so that the transmission of unwanted heat by convection is decreased again.

In addition, it is especially preferred that the at least one first wall or the second wall or both the at least one first wall and the second wall is also provided with a very reflective layer in respectively at least one of its corresponding sides. Such a very reflective layer may be made in particular of a silver foil lining. A similar insulation insert then has, in addition to the diminished convention, the advantage that unwanted heat transmission between the first frame profile and the second frame profile is also decreased by thermal radiation.

In addition, it can be advantageously provided that the insulation insert is configured in one piece. Through a one-piece configuration, particularly high stability is possible, together with a simple and therefore economical manufacturing.

In an advantageous extension the insulation insert is made of a high power thermal insulation material. Such a thermal insulation material has the advantage that due to its low thermal conductivity the distance of the components at a different temperature level in the intermediate space is not further reduced and thus the thermal advantages of the insulation insert are again reduced. according to the invention. A similar high power thermal insulation material is, for example, polyvinyl chloride (PVC).

But it can also be provided to configure the insulation insert of a high temperature resistant thermal insulation material, preferably polyamide. In particular, a similar thermal insulation material, resistant to high temperatures and possibly more thermally disadvantageous with respect to a high power thermal insulation material, can be used, if the insulation insert according to the invention must be inserted before an eventual colored coating of the frame profiles, that is, if an assembly of the frame is to be made from the first frame profile, the second frame profile, the insulating bridges and the insulation insert according to the invention before a similar color application, in particular a color coating. Due to the high temperature resistance of such a thermal insulation material, a coating of similar color can also be made subsequently, that is, after the assembly of the frame, without the insulation insert being damaged or its thermal properties are essentially worsened subsequently due to the color coating process.

The solution according to the invention is explained in more detail below by means of a drawing.

Fig. 1 shows a sectional view of a frame formed by a first frame profile 11 and a second frame profile

12. The first frame profile 11 and the second frame profile 12 are thus spaced apart from each other in an upper region by an insulating bridge 13a and in a lower region by an insulating bridge 13b. The two insulating bridges 13a, 13b respectively have an additional bridge 14a, 14b, the additional bridges 14a, 14b being introduced each time in an intermediate space 15 configured by the first frame profile 11, the second frame profile 12, as well as the two insulating bridges 13a, 13b. The extension length l of the insulating bridges 13a, 13b determines at the same time the width of the entire profile frame and therefore also at the same time the width b of the configured intermediate space 15. The wingspan w of the intermediate space 15 is determined by the wingspan of the profile and thereby determines the distance between the insulating bridges 13a, 13b.

At this point it is mentioned that, regardless of the mode of representation shown in the figures, it is also possible to provide the first frame profile 11 or the second frame profile 12 as that of the two frame profiles 11, 12 which is directed towards the exterior side of the building, thus the outdoor side.

In the region of the intermediate space 15, an antagonist blocking means 20, as well as an antagonist blocking means 21 are provided respectively spaced from each other in the first frame profile 11. A blocking means 120 of a first wall 101a of an insert of isolation 100 according to the invention meshes with the antagonist blocking means 20 according to an embodiment of the invention. The first wall 101a as well as another first wall that runs broadly parallel to it extend from the first frame profile 11 in the intermediate space 15, where they have a connection to a second wall 102 in respectively a second end region 11 of the first wall 101a, 101b corresponding in respectively a connection zone 112 configured there. The second wall 102 runs in the sectional view according to fig. 1 widely perpendicular to the first wall 101a and the first wall 101b, that is, essentially parallel to the direction of development of the first frame profile 11 and also of the second frame profile

12. According to the embodiment example of fig. 1, this second wall 102 extends respectively beyond the connection zone 112 with the first walls 101a, 101b and even more in the direction of the corresponding insulating bridge 13a, 13b. In this way the additional bridge 14a or 14b and the second wall 102 overlap partially.

While the first wall 101a has in its first final region 110 a blocking means 120 that meshes with the antagonist blocking means 20 of the first frame profile 11, a blocking means is configured in the first final region of the first wall 101b 120 which is in close contact with a stop means 21 of the first frame profile 11. Thus by the first wall 101a, the first wall 101b, as well as the second wall 102 in connection with the region of the first frame profile 11 located between the blocking means 120 a cavity 115 is configured which is embedded in the intermediate space 15. By means of this embedded cavity 115 an unwanted heat transmission by convection between the first frame profile 11 and the second profile can be effectively minimized of frame 12.

The isolation insert 100 according to the invention of the embodiment according to fig. 1 essentially presents the shape of a small Greek π. Naturally, other forms are also possible as long as the essential characteristics of the insulation insert 100 according to the invention are preserved in this case.

In the exemplary embodiment according to fig. 1, a very reflective layer 130 is also provided on both sides of the second wall 102, which can effectively reduce the transmission of unwanted heat between the first frame profile 11 and the second frame profile 12 by thermal radiation. Additionally and not shown in fig. 1 may also be provided to provide the additional bridges 14a, 14b of the insulating bridges 13a, 13b with a similarly very reflective coating, in order to be able to use this effect beyond the area of overlap between the additional bridges 14a, 14b and the second wall 102 of the insulation insert 100 according to the invention.

Fig. 2 shows a sectional view similar to fig. 1, however, the first frame profile 11 and the second frame profile 12 being further spaced from one another, so that a wider width b of the intermediate space 15 is produced.

Thanks to the universal shape of the insulation insert 100 according to the invention, a similar variation in the frame width is possible, without having to use an insulation insert 100 specially adapted thereto, that is, modified in some way in size . Rather, all the positive effects of the solution according to the invention can also be transferred to an increased frame width b, without this requiring an expensive and complicated adaptation of the dimensions of the insulation insert 100 according to the invention.

In sectional view according to fig. 3 a similar profile can be seen, also assembled from a first frame profile 11 and a second frame profile 12, into which the insulation insert 100 according to the invention is inserted. However, due to a decrease in the wingspan of the profile the insulating bridges 13a, 13b are now spaced essentially far from each other, that is, the wingspan w of the intermediate space 15 is essentially reduced with respect to the arrangement of fig. 1. Except that a larger overlapping region occurs between the second wall 102 of the insulation insert 100 and the additional bridges 14a, 14b of the insulating bridges 13a, 13b, the same insulation insert 100 according to the example is also used of embodiment that already in the dispositions of fig. 1 as well as fig. 2. With the same advantages, as described in connection with the arrangement of fig. 2, in the case of a decrease in the wingspan of the profile, an adaptation of the insulation insert 100 according to the invention can also be dispensed with, without the thermal advantages of the solution according to the invention being somewhat worsened.

In fig. 4 a corner profile arrangement is represented, that is, a profile layout with a comparatively difficult shape. In the arrangement according to fig. 4 the insulation inserts 100 are also used according to the exemplary embodiment, as they have already found use for the arrangements according to figures 1 to 3. Since the two insulation inserts 100 used according to the arrangement of fig. 4 respectively have a second wall 102 that is spaced very little in the corner region, in a comparatively complicated arrangement as shown in fig. 4, a clear decrease in unwanted heat transmission between the first frame profile 11 and the second frame profile 12 also occurs effectively due to convective processes.

In the arrangement in fig. 5 frame profiles 11, 12 with a very large wingspan are used. The intermediate space 15 of the arrangement of fig. 5 also correspondingly has a large wingspan w. In this case, two insulation inserts 100 of the exemplary embodiment are used, as they have also found use in the arrangements according to Figures 1 to 4. Also for a very large similar profile, with the solution according to the invention it is not necessary adapt the shape and / or dimension of the insulation insert 100 according to the invention to the individual case.
