Abstract

The insulating insert (100) has a wall (101a), where another wall (102) extends perpendicular to the former wall. A locking unit (120) is formed at an end portion (110) of the former wall. The locking unit is designed to be attached to a counter interlock system (20) formed in one of two profiles (11,12), or in insulating bars (13a,13b) formed by an intermediate space (15). The former wall extends substantially perpendicular to the course profile of the former frame profile in the region of the counter interlock system.

Description

The present invention relates to an insulating insert for a frame formed from a first frame profile and a second frame profile, in particular sash frames.

In such frames formed from frame profiles, in particular for windows, doors and the like, the frame profiles are usually connected by means of insulating webs. Since the frame profiles are usually made of metal, in particular of aluminum, the insulating webs used for connection to improve the thermal insulation behavior of the frame construction are formed of a poorly heat-conductive material, in particular of certain plastics. Due to the poor thermal conductivity of the plastics used in the insulating bars can be effectively minimized by such an arrangement an undesirable heat transfer - in winter from the inside of the building facing profile in the direction of the cold outside air facing profile and the summer vice versa - at least as far as the heat conduction , An undesired heat exchange by thermal radiation can be partially counteracted, for example by further, substantially parallel to the direction of the frame profiles extending webs are attached to the insulating webs, which are provided with a heat radiation reflecting layer. Furthermore, it is known by the frame profiles and the insulating bars formed gap to reduce unwanted heat transfer by convection with a foam or the like to fill.

In particular, when a variety of possible profile variants, profile widths and profile widths should be used, the previous solutions are unsatisfactory. When very wide profiles, i. Profiles with a large distance of the insulators used to each other, to be used, for example, the problem arises that each provided on the insulating webs optionally provided with a reflective layer additional webs must be extended with increasing profile width to a heat transfer by convection and / or Thermal radiation continues to be able to effectively counteract. In particular, since the insulating bars, which are used for connecting the frame profiles are prefabricated in larger quantities and should be used for different profile widths, results in a variation of the profile width, the need to make a variety of different insulating bars or store.

If foam is additionally used to prevent convection, the material requirement for this filling foam increases considerably with increasing profile width.

Furthermore, in such a solution, in which the gap is foam-filled, it is not possible to subsequently provide the frame profiles with a color coating, as would be damaged by the required high temperatures during such a color coating process, the foam used for filling the gap.

On the basis of the described problem, the present invention, the object of developing the means used to prevent the unwanted heat transfer by convection, but also by heat radiation in such a way that, especially for variable profile widths at least constant thermal properties universal insulating bars for connecting the frame profiles can be used. Further, it is an object of the invention, both in a variation of the profile width and the profile width as little as possible thermal insulation material without significantly deteriorating the thermal properties. Furthermore, the simple shortening of the profile width or frame width is desired.

The object is achieved by an insulating insert according to claim 1.

In particular, the object is achieved by an insulating insert according to the invention for the frame formed from a first frame profile and a second frame profile connected by at least two insulating strips second frame that the insulating insert according to the invention from at least a first wall and a substantially perpendicular to the at least one a first wall extending second wall, wherein at least one of the at least one first walls in a first end portion, a locking means is formed, wherein the locking means is designed, when inserting the insulating insert according to the invention in one of the first frame profile, the second frame profile and the insulating webs Intermediate space to be attached to a formed on the first frame profile Gegenarretierungsmittel, wherein in the inserted state, the at least one first wall of the insulating means according to the invention in essence extends perpendicular to the profile profile of the first frame profile in the region of Gegenarretierungsmittels.

The solution according to the invention has a whole series of advantages over the previous conventional solution. Thus, on the one hand the material requirement and also the workload and thus the resulting costs compared to a Schaumverfüll process is considerably reduced. In addition, it is possible for various variable profile widths and profile widths to form the insulating insert according to the invention in a unit size, ie to design it uniformly for different profile widths and profile widths. The fact that the insulation insert according to the invention is attached only to a frame profile, a large variability is given and the insulation insert according to the invention can be used for different profile widths and profile widths alike and with similarly good effect. Another advantage is that the insulation insert according to the invention is also suitable for difficult profile shapes such as corner profiles.

Due to the fact that the insulating insert according to the invention is formed from at least one first wall and one second wall, which extends substantially perpendicularly to the at least one first wall, it is possible, in particular, to use identical insulating webs (ie in particular with additional webs of equal length) and one use similar insulation insert according to the invention for different profile widths. The fact that the second wall of the insulating insert according to the invention extends in the same way substantially parallel to the direction of the first frame profile as the additional, projecting into the gap webs of the insulating bars, results in an overlap area between this second wall and the additional webs, even with different profile widths, so that an undesirable heat transfer between the frame profiles can be effectively reduced by convection.

Advantageous developments of the invention are specified in the subclaims.

For example, it is provided that the insulation insert according to the invention has at least two first walls, the at least two first walls and the second wall of the insulating insert defining at least one cavity together with the first frame profile in the inserted state of the insulation insert. By such at least one cavity embedded in the gap, it is possible to further reduce the undesirable convection.

Furthermore, it may be provided in such an embedded at least one cavity that on the first frame profile a stop means is formed, on which at least one of the at least two first walls of the insulating insert partially rest. This is particularly advantageous if only one of the at least two first walls, a locking means is formed, which is in engagement with a corresponding Gegenarretierungsmittel on the first frame profile. By providing a stop means formed on the first frame profile and in that the further wall of the at least two first walls, which is generally not provided with a locking means, at least partially bears against this stop means, a substantially tight seal of the at least one formed and into the intermediate space given embedded cavity, so that an effective Reduction of heat transfer by convection is ensured. Such a stop means, instead of, for example, a further Gegenarretierungselementes in addition to those provided for the other of the at least two first walls Gegenarretierungsmitteln, has the further advantage that low manufacturing tolerances, in particular for the insulation insert according to the invention the accuracy of fit of the insulating insert does not adversely affect that the heat transfer by convection is no longer sufficiently reduced.

Taking advantage of this effect, it may also be provided that the insulating insert form such a flexible, that in the inserted state, a substantially tight closure of the at least one formed cavity is given. This is particularly advantageous when at least one of the at least two first walls of the insulating insert rests against a stop means. By suitable dimensioning such a flexible trained insulating insert can be used due to the restoring forces clamping into the Gegenarretierungselement and the stop means, so that in addition to the desired largely tight completion of at least one cavity formed a secure fit, i. a secure position holding the insulation insert is guaranteed in the inserted state. Of course, it is also possible in this context, in such a clamping principle, the Gegenarretierungsmittel and the abutment means substantially similar, for example, each form a curved projection in the first frame profile, so that the locking means and the abutment means in such a clamping solution together the position holding the insulation insert ensure in the space.

Furthermore, it is provided that the second wall of the insulating insert is arranged in a second end region, remote from the first end region, of the at least one first wall. This ensures, in particular, that with a variation of the profile width, ie with a variation of the expansion length of the insulating webs any interfering projections of the at least one first wall beyond the second wall are also present, which are disadvantageous in a possibly required shortening of the profile width or frame width could.

In a particularly preferred manner, it is provided that the insulating insert is formed symmetrically along an axis of symmetry running parallel to the at least one first wall. Such a symmetrical shaping ensures, in particular, that insertion of the insulating insert into the intermediate space can not be accidentally reversed. In this context, it is particularly advantageous to design the locking element such that it can be in contact both with a suitable counter-locking element and with a suitable stop means. For this purpose, in general, a symmetrical in cross-section shape of the locking element offers.

Furthermore, it is preferably provided that the second wall extends beyond a connection region with the at least one first wall. In other words, it is provided that the second wall extends beyond an area in which it is connected to the at least one first wall, in each case in the direction of the insulating webs. In particular, if exactly two first walls and a second wall are provided, then results in an insulating insert whose shape in cross section resembles the shape of a small Greek π. In addition to the convection reduced by the at least one formed embedded cavity, an overlap with optionally further webs attached to the insulating webs is then additionally provided so that the undesired heat transfer by convection is again reduced.

Furthermore, it is provided in a particularly preferred manner that the at least one first wall or the second wall or both the at least one first wall and the second wall is or are provided on at least one of their respective sides with a highly reflective layer. Such a highly reflective layer may in particular consist of a silver foil coating. Such an insulating insert then has the advantage, in addition to the reduced convection, that the unwanted heat transfer between the first frame profile and the second frame profile is also reduced by thermal radiation.

Furthermore, it can be advantageously provided that the insulation insert is integrally formed. By one-piece training is a special high stability combined with a simple and therefore cost-effective production possible.

In an advantageous development, the insulating insert consists of a high-performance heat insulation material. Such a thermal insulation material has the advantage that it does not additionally reduce the spacing of components at different temperature levels due to its low thermal conductivity in the intermediate space and thereby reduces the thermal advantages of the insulation insert according to the invention again. Such a high-performance thermal insulation material is, for example, polyvinyl chloride (PVC).

Equally, however, it may also be provided to form the insulation insert from a high-temperature-resistant heat insulation material, preferably made of polyamide. Such, optionally thermally unfavorable compared to a high-performance heat insulation material high temperature resistant thermal insulation material can be used in particular when the insulation insert according to the invention is to be used before a possible color coating of the frame profiles, so if an assembly of the frame from the first frame profile, the second frame profile, the Insulating webs and the insulation insert according to the invention before such an application of paint, in particular a color coating to take place. Due to the high-temperature resistance of such a thermal insulation material, such a color coating can also be done subsequently, ie after assembly of the frame, without the insulation insert being damaged or its thermal properties subsequently being significantly impaired by the color coating process.

In the following, the solution according to the invention is explained in more detail with reference to a drawing.

Fig. 1 shows a sectional view of a frame formed from a first frame 11 and a second frame profile 12. The first frame profile 11 and the second frame profile 12 are connected to one another in an upper region by an insulating web 13a and in a lower region by an insulating web 13b spaced from each other. The two insulating webs 13a, 13b each have an additional web 14a, 14b, with the additional webs 14a, 14b respectively extending into a space 15 formed by the first frame profile 11, the second frame profile 12 and the two insulating webs 13a, 13b. The expansion length I of the insulating webs 13a, 13b simultaneously determines the width of the entire profile frame and thus at the same time the width b of the formed intermediate space 15. The width w of the intermediate space 15 is determined by the profile width and therefore determines the distance between the insulating webs 13a, 13b to each other.

It should be noted at this point that, regardless of the manner of representation shown in the figures, it is equally 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 the outside of the building, ie Facing the weather side.

In the region of the intermediate space 15, a counter-locking means 20 and a stop means 21 are respectively provided at a distance from the first frame profile 11. With the Gegenarretierungsmittel 20 engaged is a locking means 120 of a first wall 101a of an insulating insert 100 according to the invention according to an embodiment of Invention. The first wall 101a and a further first wall 101b running substantially parallel thereto extend from the first frame profile 11 into the intermediate space 15, where in each case a second end region 111 of the respective first wall 101a, 101b in each case a connecting region 112 formed there Have connection to a second wall 102. The second wall 102 extends in the sectional view according to Fig. 1 substantially perpendicular to the first wall 101a and the first wall 101b, ie substantially parallel to the direction of the first frame profile 11 and also the second frame profile 12. According to the embodiment of Fig. 1 This second wall 102 extends beyond the connecting region 112 with the first walls 101a, 101b and further in the direction of the respective insulating web 13a, 13b. As a result, the additional web 14a or 14b and the second wall 102 partially overlap.

While the first wall 101a has in its first end region 110 a locking means 120 which engages with the counter-locking means 20 of the first frame profile 11, in the first end region 110 of the first wall 101b, a locking means 120 is formed, which on a stop means 21 of the first frame profile 11 is tight. As a result, a cavity 115, which is embedded in the intermediate space 15, is formed by the first wall 101a, the first wall 101b and the second wall 102 in conjunction with the region of the first frame profile 11 located between the locking means 120. Through this embedded cavity 115, an undesirable convection-induced heat transfer between the first frame profile 11 and the second frame profile 12 can be effectively minimized.

The insulation insert 100 of the embodiment according to FIG Fig. 1 has essentially the shape of a small Greek π. Of course, other shapes are possible, as long as the essential features of the insulating insert 100 according to the invention are maintained.

In the embodiment according to Fig. 1 In addition, a highly reflective layer 130 is provided on both sides of the second wall 102, which can effectively reduce the unwanted heat transfer between the first frame profile 11 and the second frame profile 12 by thermal radiation. In addition and in Fig. 1 not shown, it can also be provided to provide the additional webs 14a, 14b of the insulating webs 13a, 13b with a similar highly reflective coating to this effect beyond the overlap region between the additional webs 14a, 14b and the second wall 102 of the insulating insert according to the invention 100 to be able to use.

Fig. 2 shows a sectional view similar Fig. 1 However, here, the first frame section 11 and the second frame section 12 are further spaced from each other, so that a larger width b of the gap 15 results.

Due to the universal shaping of the insulating insert 100 according to the invention, such a variation of the frame width is possible without a specially adapted, i. would have to be used in its size in any way modified insulation insert 100. Rather, all the positive effects of the solution according to the invention are also transferable to such an enlarged frame width b without the need for a costly and complicated adaptation of the dimensions of the insulating insert 100 according to the invention.

In the sectional view according to Fig. 3 is a similar, also composed of a first frame section 11 and a second frame section 12 frame to see in which the insulation insert 100 according to the invention is used. By reducing the profile width, however, the insulating webs 13a, 13b now substantially far from each other, ie, the width w of the gap 15 is opposite to the arrangement Fig. 1 significantly reduced. With the exception that there is a larger overlap area between the second wall 102 of the insulating insert 100 and the additional webs 14a, 14b of the insulating bars 13a, 13b, the same insulating insert 100 according to the exemplary embodiment continues to be used, as in the case of the arrangements Fig. 1 such as Fig. 2 for use. With the same advantages as in connection of the arrangement Fig. 2 described, can be dispensed with a reduction of the profile width on an adjustment of the insulating insert 100 according to the invention without the thermal advantages of the inventive solution deteriorate in any way.

In Fig. 4 is a Eckprofilanordnung, ie a profile arrangement shown with a comparatively difficult shape. In the arrangement according to Fig. 4 Insulation inserts 100 according to the exemplary embodiment are also used, as already described for the arrangements according to FIGS FIGS. 1 to 3 Have found use. In that the two according to the arrangement Fig. 4 Insulating inserts 100 each having a second wall 102, which are spaced very little from one another in the corner region, will also be used in a comparatively complicated arrangement like that according to FIG Fig. 4 a significant reduction of the unwanted heat transfer between the first frame section 11 and the second frame profile 12 by convective operations effectively reduced.

In the arrangement in Fig. 5 come frame profiles 11, 12 with a very large width used. Accordingly, also the gap 15 of the arrangement Fig. 5 a large width w. In this case, two Isolationseinszeze 100 of the embodiment are used, as they already in the arrangements according to the FIGS. 1 to 4 Have found use. Even for such a very wide profile width, it is not necessary with the solution according to the invention to adapt the shape and / or the dimensions of the insulating insert 100 according to the invention to the individual case.
