Description

The invention relates to a profile arrangement preferably of wing profiles of a rotary sliding window, a rotating window, a sliding window or corresponding doors, which has a first profile and a second profile, wherein the profiles can be brought into a closed position.

Usually, the profiles of such profile arrangements, ie the first and the second profile, each formed from an outer profile and an inner profile, wherein the respective outer and inner profiles are connected to each other by means of at least one insulating web. In particular, in rotary sliding profile arrangements, the profiles are partially opposite each other in a closed position along a termination area.

In general, conventional profiles are approximately U-shaped, d. H. the mutually parallel legs of the opposite in a closed position substantially U-shaped profiles are approximated, while the respective at least one insulating web, which connects the outer with the inner profiles, respectively forms the transverse leg of the U.

In a closed position then define the first and the second profile, which are each U-shaped and in the closed position relative to the respective U-shape facing the parallel legs, a cavity.

Even if, at the respective opposite parallel legs of the opposing U-shaped profiles a plant seal or the like is provided, conventional profiles have the disadvantage that an undesirable heat transfer between the outside and the inside, ie between the respective outer and the respective inner profiles is favored by this cavity.

Patent Application EP 0 143 745 A2 discloses a Profilandordnung with all features of the preamble of claim 1.

It is therefore an object of the present invention to develop such conventional profile arrangements in such a way that the thermal properties of the profile arrangement are improved.

According to the invention this object is achieved by a profile arrangement according to claim 1.

By the at least partial intrusion of the at least one insert into the cavity, there is the particular advantage that an undesired heat transfer between the outside and the inside, d. H. in the installed state of the profile arrangement according to the invention between the outer and the inner profiles when the profiles are in a closed position, is effectively reduced.

Advantageous developments of the solution according to the invention are specified in the subclaims.

For example, it is provided that the first profile and the second profile are mutually displaceable. Furthermore or additionally, it is possible that the first profile and the second profile are formed pivotable relative to each other. Due to the fact that, according to the invention, the at least one insert only projects at least partially into the cavity, such shifting or pivoting of the profiles is not hindered by the insert, so that a clear reduction of the profile is also possible when used on profiles which are displaceable relative to one another and / or against one another gives unwanted heat transfer between the respective outer and the respective inner profiles.

According to the invention, the at least one insert has a wall region and this wall region extends at least partially into the cavity. Preferably, the edge region is formed relatively thin, resulting in an advantageous compared to, for example, a central center seal low weight. Furthermore, such a wall region is comparatively inconspicuous and thus affects the optics only insignificantly in the opened state of the profile arrangement, that is to say, for example, when the sliding window is open or the sliding door is open or the wings are pivoted in a corresponding manner.

Furthermore, it can be provided that the insert is formed from a material which conducts the heat poorly, preferably from polyvinyl chloride (PVC) or polyamide (PA). As a result, the unwanted heat transfer can be further reduced.

so kann durch einen Einsatz aus Polyamid die Wärmeleitfähigkeit dieser Profilanordnung auf ca. $1,8\frac{W}{m^2*K}$

gesenkt werden. Entsprechend kann durch einen Einsatz aus Polyvinylchlorid die Wärmeleitfähigkeit auf etwa $1,83\frac{W}{m^2*K}$

gesenkt werden.For example, in a typical profile arrangement, the thermal conductivity is without use $2.23\frac{W}{m^2*K}.$

Thus, by using polyamide, the thermal conductivity of this profile arrangement to approx. $1.\mathrm{8th}\frac{W}{m^2*K}$

be lowered. Accordingly, by using polyvinyl chloride, the thermal conductivity to about $1.83\frac{W}{m^2*K}$

be lowered.

Of course, the numerical values mentioned are only to be understood as examples and are intended to illustrate the general effect of a profile arrangement according to the invention, in which use is made of a material which conducts the heat poorly.

Furthermore, it can be provided that the insert has a substantially perpendicular to the wall region extending fastening web. This results in a substantially T-shaped or, in the case of an extended wall area, a cross-shaped insert. By providing such a fastening web, the arrangement of the insert can be further optimized, so that the wall region can advantageously extend partially into the cavity.

In this case, it can also be provided that the fastening web of the at least one insert is fastened to the at least one insulating web. By attachment to the at least one insulating bar results in a particularly simple construction. Furthermore, by providing appropriate mounting options on the insulating web, for example by providing a recess receiving the mounting web or the like, the positioning and arrangement of the insert can be further optimized, so that the wall portion at least partially extends into the cavity such that a effective reduction of heat transfer is achieved.

gesenkt werden.According to the invention, it is provided that the wall region of the at least one insert is provided at least in regions with a heat-reflecting layer. Preferably, such a heat-reflecting layer in the form of a heat-reflecting film is at least partially applied to the wall region of the at least one insert. As a result, the unwanted heat transfer along the cavity is further reduced. With reference to the profile arrangement listed above by way of example, it can be achieved by at least partially applying a profile arrangement such heat-reflecting film, the thermal conductivity further to about $1.60\frac{W}{m^2*K}$

be lowered.

Furthermore, it can be provided that the wall area extends into the cavity substantially perpendicular to the at least one insulating bar. This takes into account the fact that an undesirable heat transfer can be reduced most effectively if the wall region is arranged perpendicular to the thermal gradient along the cavity. As a result, an even more effective reduction of the unwanted heat transfer is possible.

Furthermore, it can be provided that the wall region extends substantially centrally between the first outer profile and the first inner profile or the second outer profile and the second inner profile into the cavity. By means of such a central arrangement, a possible undesired thermal interaction between the profile parts and the insert or the wall region is largely minimized, which in turn results in an improvement in the heat transfer properties of the profile arrangement.

Furthermore, provision can be made for a first insert and a second insert to be provided, whose wall regions each extend from a connection region of the first inner profile to the first outer profile or from a connection region of the second inner profile to the second outer profile extends into the cavity.

In a closed position of the profiles then complement the beneficial thermal effects of the two inserts or their wall areas. If the profiles are brought by pivoting, pushing or the like from the closed position to an open position, then each of the profiles, ie provided on the first profile and the second profile each have their own use, resulting in consistently good thermal properties on the one hand the load to be carried, ie distributed the weight of the respective inserts on two profiles and on the other hand, the visual impression is improved.

In this context, it may be provided that the wall area of the first insert and / or the wall area of the second insert in the closed position of the profiles each extend approximately to a center line. This center line is substantially perpendicular to the wall portion and extends substantially centrally between the first profile and the second profile when the profiles are in the closed position. Ideally, the ends of the two wall portions of the inserts are in the closed position opposite, so that there is a nearly continuous wall, which perpendicular to the direction of connection of the profiles, d. H. runs perpendicular to the insulating webs within the cavity. This substantially symmetrical structure results in optimal weight and load distribution and an attractive visual impression optimum reduction of unwanted heat transfer.
