Description

The present invention relates to a frame profile for a window or a door and a blend profile for the formation of such a frame profile.

Frame profiles for windows or doors are basically known and are used for example in the EP 2 476 854 A2 or the DE 10 2007 047 604 described. Thus, it is known that basic profiles for the mechanical stability of such a frame profile are provided in which z. B. door leaves or windows are used. In order to achieve sufficient thermal insulation for the frame profile, heat insulating materials or hollow chambers are used in known solutions between the inside and the outside of this base profile. It is also known that for improving the thermal insulation on the outside of a thermal insulation material is placed, which can be covered by a blend profile.

A disadvantage of known frame profiles and in particular in the known blind profiles is that over the fixed connection of the individual components with each other thermal stresses can arise. Thus, when exposed to the sun on the outside of the base profile, this outside will heat up more than the inside. The better the thermal insulation works and, accordingly, the higher the quality of the frame profile, the greater will be the temperature difference between outside and inside. Since, however, the materials of the base profile usually do not differ between the outside and the inside, this different tempering results in different ones real thermal expansions. In extreme cases, this can lead to a delay of the entire frame profile. This can also lead to consequential problems such as the reduction of the tightness of the frame profile. The known blend profiles are in the solutions described in the EP 2 476 854 A2 or the DE 10 2007 047 604 unable to prevent a corresponding distortion of the frame profile. In case of doubt, they even amplify the problem since there can also be an additional heat distortion due to the firm connection between the base profile and the corresponding glare profile.

It is an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention, in a cost effective and easy way to achieve a good insulation while avoiding deformation of the frame profile as possible.

The above object is achieved by a frame profile with the features of claim 1 and by a blend profile with the features of claim 10. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that are described in connection with the frame profile according to the invention apply, of course, also in connection with the blend profile according to the invention and in each case vice versa, so that with respect to the disclosure of the individual invention aspects always reciprocal reference is or can be.

In a frame profile according to the invention this is designed for a window or a door. For this purpose, the frame profile on a base profile with an inside and an outside, wherein between the inside and the outside at least sectionally a heat insulation is arranged. An inventive frame profile is characterized in that on at least one of the two sides of a blend profile is movably mounted in its main extension direction and covers the base profile on the corresponding side at least in sections.

An inventive frame profile thus serves to provide a corresponding profiling of a window or a door available. In this case, the base profile preferably has corresponding accommodation options in order to hold a window pane or a door leaf.

The inside and the outside of the base profile are to be distinguished from each other in particular on the basis of the corresponding installation situation. Thus, the outer side of the base profile in the installation is preferably directed from a building to the outside, while the corresponding inner side is directed into the interior of the building. The thermal insulation can be made available in a variety of ways. So it is possible that individual air chambers between the inside and the outside provide the thermal insulation. Also insulating materials which fill such chambers completely or partially are used for thermal insulation.

The blend profile covers the base profile on the corresponding side at least in sections. Thus, the blend profile has different extension directions. According to the invention, the blend profile is made relatively thin so that it is also possible to speak of a blend profile sheet. In addition, the blend profile extends along the respective extent of the base profile. Such profiles usually have an elongated main extension direction, so that the corresponding width of the base profile and thus also the blend profile clearly smaller compared to its length fails. In this way, the main extension direction of the blend profile can also be referred to as the longest extension direction of the blend profile in the three dimensions.

The inventive provision of the blend profile is now a cover of the base profile. This cover is equal to a shadow, so that z. B. in strong sunlight on the frame profile, this shading protects the base profile in excess of the extent of strong or faster heating by the sunlight. Rather, the blend profile heats up strongly and / or quickly instead of the base profile, so that a compensation possibility is created here by the movable attachment of the blend profile. In strong sunlight, therefore, the blend profile heats up by the shading and thus the cooling of the base profile. When heating the blend profile, this will expand on the basis of its material and as a function of the thermal expansion coefficient. However, this expansion is taken into account by the movable attachment to the base profile, so that no mechanical stresses with respect to the main extension direction are passed on from the blend profile to the base profile with a corresponding thermal expansion in this direction.

Of course, a movable attachment may be preferred in other directions of extension of the blend profile. For example, in the minor extension direction, z. B. the width of the blend profile, an additional mobility in the attachment may be provided. The attachment is thus carried out by a simple or even by a double floating bearing between Blendprofil and base profile.

It is preferable if the blend profile covers most of the base profile or even achieves complete coverage of the base profile. The greater the shadowing of the base profile is made possible, the stronger the inventive effect of the deformation protection of the base profile. In addition, it should be noted that for the mechanical stability of the window or the door substantially exclusively the base profile brings with it the corresponding mechanical rigidity. Although the blend profile is based on the base profile, it adds little or nothing to the mechanical stabilization.

A frame profile is in the context of the present invention, in particular a rope-shaped profile. Of course, a round profile, a triangular profile or a typical rectangular profile for a window or a door can be made available from individual strand-like profiles over corner areas. Accordingly, the blend profiles also extend into such corner sections between individual sections of the frame profile, so that there likewise the advantage according to the invention can be achieved.

It may be advantageous if, in a frame profile according to the invention, the blend profile completely or substantially completely covers the corresponding side of the base profile, the blend profile having at least one expansion gap in its main extension direction. As has already been explained, the protection effect and thus the inventive advantages of the draft protection for the base profile are enhanced by increasing the coverage possibility by means of the blend profile. Because the blend profile has at least one expansion gap in its main extension direction, jamming or wedging of the blend profile upon intense heating can be avoided. The expansion gap relates in particular to the normal temperature or room temperature without a necessary heat balance situation. Now if an expansion of the blend profile increases the length along the main extension direction of the blend profile. The intended expansion gap is reduced in this way. The size of the expansion gap is thus preferably adapted to the respective site of use and / or the expected temperature fluctuations. Of course, the blend profile completely or at least partially rest completely flat on the corresponding side of the base profile. However, it is also possible that an additional air chamber is defined by a distance between blend profile and base profile. Thus, a heat transfer between blend profile and base profile is reduced by contacting heat conduction or even completely avoided. This is done in particular in connection with fasteners used, as will be explained later.

A further advantage may be if, in a frame profile according to the invention, at least two fastening means fasten the blend profile to the base profile, the mobility along the main extension direction being formed between the fastening means and the blend profile and / or the fastening means and the base profile. The use of fasteners makes it possible to reduce the contacting portions between blend profile and base profile with respect to the contact surface. Contacting heat conduction is reduced in this way or even partially avoided. The fastening means are designed in particular for reversible attachment, so that in case of a defect or optical damage of the blend profile this can be replaced without any problems and effort. A frame profile, which for holding a window z. B. is firmly installed in an opening of the building, can remain there in such a case. The relative movement, which is necessary for the mobility of the blend profile according to the invention, can be achieved both by the relative movement between blend profile and fastening means, as well as by the relative movement be provided between base profile and fastener. Of course, a combination of these two relative movement possibilities is conceivable. In this case, the surfaces of the base profile and / or the blend profile as well as the surface of the fastener may be adapted to a corresponding reduction in friction for the movement. The use of fasteners also makes it possible to provide preferred material pairings between blend profile and fastener or between base profile and fastener for friction reduction.

• Kunststoffclip
• Edelstahlclip
• Kunststoffprofil

In the frame profile according to the preceding paragraph, it may be advantageous if at least one of the following is used as the fastening means:

• Plastic clip
• stainless steel clip
• Plastic profile

A distinction between a fastening means in the form of a clip and in the form of a profile can be made such that a clip is preferably designed for elastic mounting. Thus, attachment portions of the plastic clip or stainless steel clip can be elastically deformed to allow attachment to the base profile and / or the blend profile. The formation of a profile made of plastic or even metal or stainless steel allows a lateral sliding, which equals the corresponding main extension direction of the blend profile. The list is, of course, a non-exhaustive list.

It is also advantageous if in a frame profile according to the invention, the blend profile at least one attachment portion for attachment has on the base profile, wherein the at least one attachment portion has a friction-optimized surface. A friction optimization takes place in particular with reference to a reduction of the static friction. For severe heating situations, eg. B. by sunlight, with concomitant rapid expansion of the blend profile, accordingly, the release between the blend profile on the mounting portion and the base profile or the corresponding fastener by reduced static friction faster and easier. In particular, a noisy release of this contact during the relative movement between the blend profile and base profile is reduced in this way or even completely avoided. The attachment portion may, for. B. generated by surface treatment. Thus, grinding and / or polishing is possible to minimize the roughness of the attachment portion for reduction of stiction. Of course, an adaptation to a corresponding material of the base profile and / or the fastening means for a friction reduction can be made possible. A coating of the attachment portion is conceivable within the meaning of the present invention.

A further advantage is when, in a frame profile according to the invention, the blend profile at least in sections has a reflection surface on the outer surface for a reflection of heat radiation. The reflection surface can, for. B. be produced by polishing, so einstrahlendes sunlight is reflected more easily or to a greater degree. A reduction in the heating of the blend profile accordingly also leads to a further heat protection of the base profile and thus improves the protection against distortion of the base profile. The inside of the blend profile with respect to the base profile is in particular made matt or substantially matt in order to reduce the transmission of a heated blend profile to the base profile by thermal radiation. In particular, the blend profile also has an insulation or a partial insulation against heat conduction to the base profile in order to achieve an improved protective effect for the base profile also for this heat transfer phenomenon.

A further advantage is when, in a frame profile according to the invention, the blend profile has at least two blend profile components which adjoin one another in the main extension direction of the blend profile. As can be seen here, the blend profile can of course have any number of individual blend profile components. This not only makes it impossible to provide complex geometries of frame profiles for a wide variety of window shapes available, but also to cover any size of the frame profile by modular construction of individual Blendprofilbauteilen. Thus, a high number of Blendprofilbauteilen can be generated by identical parts, so that a price reduction for the creation of the blend profile is possible.

In a frame profile according to the preceding paragraph, it may be advantageous if the at least two Blendprofilbauteile overlap with each other in sections. The overlapping ensures that z. B. the described expansion gap is not visible from the outside. Rather, the expansion gap is also located in this overlapping area, so that the expansion gap is not visible despite the extent and thus independent of the actual temperature situation. The shading of the base module of the base profile is also improved over this section overlap. Of course, such an overlap can also be provided in a corner region of the frame profile.

Another advantage can be achieved if, in a frame profile according to the invention, the blend profile is fastened in a form-fitting manner to the base profile. A positive connection can z. B. can be achieved by elastic mounting as clipping or by the lateral sliding as a profile solution. In this case, the positive connection is provided in particular with a degree of freedom in the direction of the main extension direction for the corresponding mobility.

Likewise provided by the present invention is a blend profile for the fastening, which is movable in its main extension direction, to a base profile for the at least partial covering of the base profile to form a frame profile according to the invention. Accordingly, to form a frame profile according to the invention, the blend profile according to the invention brings about the same advantages as have been explained in detail with reference to a frame profile according to the invention.

Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawings, embodiments of the invention are described in detail. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination. They show schematically:

a further embodiment of a frame profile according to the invention.

The Figures 1 and 2 show a first embodiment of a frame profile according to the invention 10. This has a two-part base profile 20, wherein between the outside 24 left and the inside 22 right heat insulation 26 is provided in the form of a hollow chamber. In FIG. 1 an exploded view is shown as with the aid of a fastener 40 to a corresponding mounting portion 36 a positive fastening between the base profile 20 and blend profile 30 is possible.

FIG. 2 shows the assembled situation, wherein in this frame profile 10, both on the inside 22, and on the outside 24, a corresponding blend profile 30 is attached. It is also easy to see how between the respective side 22 and 24 and the respective blend profile 30, an air chamber for additional insulation is formed. In this way, shading is made available to substantially the entire base profile 20, so that in the case of heating by strong sunlight, this is essentially completely limited to the blend profile 30. It is also easy to see that contacting surfaces between the blend profile 30 and the base profile 20 are reduced or avoided, so that a transfer of the heated heat from the blend profile 30 is made to the base profile 20 only to a small extent by heat conduction.

The FIGS. 3 and 4 show a further embodiment of a frame profile according to the invention 10. In a schematic, lateral sectional view, the base profile 20 between the inside 22 and outside 24 here with a material for thermal insulation 26 is provided. On the outside 24 was fastened by means of fastening means 40, a blend profile 30, which is designed to be movable along the main extension direction 32. The mobility is particularly in the correlation of FIGS. 3 and 4 to recognize.

FIG. 4 shows the embodiment according to FIG. 3 but at a higher temperature. Thus, a heat balance could take place here, which takes place by heating the blend profile 30. The blend profile 30 here consists of two or even more blend profile components 30a and 30b. These overlap at the front end S of the left diaphragm 30a, so that over a bending edge B of the diaphragm 30a, a corresponding expansion gap 34 is covered. When heating, z. B. by sunlight, the length of the two Blendprofilbauteile 30a and 30b increases along the main extension direction 33, so that correspondingly reduces the expansion gap 34.

FIG. 5 schematically shows a corresponding solution in the corner region of a frame profile 10. Again, the blend profile 30 again has two Blendprofilbauteile 30a and 30b, which overlap each other. Behind the overlap region, the blend profile component 30a of the expansion gap 34 is provided between the corresponding front end S of the blend profile 30b and the bending edge B. The functionality the draft protection for the base profile 20 takes place in the same manner as with respect to FIGS. 1 to 4 has been explained.

The above explanation of the embodiments describes the present invention solely by way of example. Of course, individual features of the embodiments, if technically feasible freely combined with each other, without departing from the scope of the present invention.
