Description

Field of the invention

The invention relates to a composite profile of at least one composite unit, which consists of at least two metal connection profiles, which are connected to each other via at least one intermediate, made of plastic connection profile for isolation, wherein the respective mutually facing sides of the at least two connection profiles and the at least one connection profile can be positively connected to each other at connection points.

Background of the invention

Such composite profiles are usually used for door or window systems and facade elements and usually consist of two metallic profile elements, which are connected via an intermediate plastic profile with each other. The intermediate plastic profile has a low thermal conductivity and thus serves as a thermal insulation element for insulation.

State of the art

In the DE 198 12 190 Cl Such a composite profile is disclosed, which consists of two metal connection profiles, which are connected via a connection profile. A connection is in this case achieved in that the connection profiles each have two extending in the profile longitudinal direction U-shaped grooves, into which corresponding anchoring webs of the connection profile are set. The positive connection is achieved in that the free edges of the anchoring grooves of the connection profiles are cold formed after inserting the anchoring webs of the connection profile. In addition, the anchoring grooves, as well as the corresponding anchoring webs of the connecting profile along the longitudinal direction in each case have a toothing in order to prevent an axial displacement of the elements to one another.

A disadvantage of a composite profile of this type is that an additional post-processing step in the form of cold forming is necessary to positively connect the connection profiles with the connection profile. By this additional deformation of the connection profiles stresses are also introduced into the system, deteriorates the Verbundprofilgeradheit and causes a twisting and a Endenaufsprung.

In the DE 195 31 345 C1 discloses a composite profile for windows or doors, in which a metallic outer and inner profile are connected via an existing plastic intermediate profile. Here, the intermediate profile is attached to two pin-like formations of the metallic outer profile, while the metallic inner profile is inserted into the intermediate profile. Only by attaching with a screw in a wooden frame or masonry is the individual parts of a composite profile. A disadvantage of this embodiment is that the use of an additional connecting element in the form of a screw is necessary to hold together the two metallic profile elements and the existing plastic intermediate profile. Thus, such a composite profile without the use of an additional fastener can not be produced. The use of screw elements thus increases the effort during assembly of the composite profile on site.

task

The invention is therefore based on the object to provide a composite profile which is held together form-fitting without further post-processing step during assembly or additional fasteners.

Summary of the invention

The object is achieved in that a connection profile at its, the connection elements facing connection points each have at least one bow-shaped design and an elastic deformation of at least one bow-shaped training in at least one Hinterhakungsmöglichkeit a respectively associated, corresponding to the bow-shaped training recess of the respective connection profile einclippbar is to achieve fastener elementless connection. By this measure, a simple assembly can be done by clipping the bow-shaped training in the respective corresponding recesses, while at the same time can be dispensed with additional fasteners. It can thus be created with low assembly costs a positive, permanent connection.

The term "bow-shaped" here means a cross-section, which is composed of a shaft and at least one subsequent leg. Thus, the formation of the connection points when using a leg has a hook shape and when using two legs on an anchor or hammerhead-shaped contour. The respective legs may extend from the shaft to form a tip or form a rounding in this area.

According to an advantageous embodiment of the invention takes place for clipping the elastic deformation on the shaft of the bow-shaped training. This makes it possible to make the remaining part of the bow-shaped training robust.

In a further development of the invention takes place for clipping the elastic deformation on at least one leg of the bow-shaped training. This has the advantage that the shaft of the bow-shaped design can be formed as a rigid part and thus is resistant to stress.

According to a further advantageous embodiment of the invention, the at least one Hinterhakungsmöglichkeit in the recess is mutually arranged to at least one connection profile. The advantage here is that by such an arrangement a wandering of the bow-shaped training is prevented from the Hinterhakung.

Advantageously, further, the space in the recess are designed such that after clipping the shaft of the respective bow-shaped training depending on the contact with the Hinterhakungsmöglichkeit at the respective location in a certain elastic deflection and thus along the axial extent of the at least one connecting profile overall results in a wave-shaped deflection of the shaft. This reduces the risk of axial displacement between the connection profile and the connection profiles. Because for one Such relative movement between the parts of the shaft of the respective bow-shaped training would constantly subjected to a changing elastic deflection in order to follow the Hinterhakungsmöglichkeit. This counteracts an axial relative movement corresponding resistance.

In a development of the invention, the respective corresponding recess of the respective connection profile has a rib-like profiling pointing in the direction of the at least one connection profile. By this profiling, the risk of axial displacement of the connection profiles and the connection profile is prevented from each other. Because by the ribbing, which corresponds to the contour of the connection profile, a positive and non-positive connection is made and thus oppose a shift resistance.

In a further embodiment of the invention, the connection profile on a, in the mounted state of the profiling of the respective connection profile opposite surface knurling or cross-stamping. By this measure, a positive and non-positive connection with the profiling of the connection profiles is further improved by impressing this structure in the plastic of the connection profile and thus further reduces the risk of displacement of the connection profiles and the connection profile to each other.

In a further development of the invention, the at least two connecting profiles each have at least one contact line spaced apart from the connection points with the at least one connecting profile via a trained toothing. Impressing the teeth of these teeth in the plastic of the connection profile represents a further improvement to prevent axial movement between the connection profiles and the connection profile.

In a further embodiment of the invention, such a toothing is also formed on the side of the connection profile and engages with the respective corresponding toothing of the respective connection profile. By intermeshing teeth on both sides, a reliable and optimal connection for preventing axial movement between the parts is easily achieved.

In a further development of the invention, an adhesive can be introduced before or after the assembly of the composite profile in the region of the bow-shaped formation. By this measure, a return movement of the barb-like approach of the bow-shaped training is reliably prevented and thus prevents the connection from rising even at very high loads.

In a further embodiment of the invention, the connection profiles consist of a cold-rolled steel material. By means of this manufacturing method, the profiles can be produced very precisely, while at the same time the higher strength and the high modulus of elasticity of the steel provide a load-bearing profile element.

In a further development of the invention, the connection profiles have a defined cavity in the area of the connection points. In this way, the connection profiles can expand when clipping the connection profile in the context of the cavity, which facilitates the insertion of the bow-shaped design in the corresponding recess and also causes the side walls of the recess press after assembly to the connection profile.

Preferably, the connection profile is made of polyamide with glass fiber reinforcement. By using this material, the necessary strength and flexibility for clipping into the recess of the connection points of the connection profiles is possible without that the connection profile breaks at these locations. Most preferably it is a conditioned plastic. The advantage here is that the elasticity is increased by the use of such a plastic.

In a further embodiment of the invention, the at least one connecting profile has in each case two bow-shaped projections directed counter to the at least two connecting profiles, each having an elastically deformable leg, wherein the legs are arranged facing each other, and the connection profiles have connection points facing the at least one connecting profile in each case via two recesses corresponding to the bow-shaped formations. By the opposite legs of the connection profile on the respective opposite sides of the connection profiles these stabilize each other in the mounted state, so that a release of the connection profile from the respective connection profile without destruction is impossible. Thus, this represents a very high loadable connection.

In a further development of the invention, the connection profiles are connected to one another via two individual connecting profiles, each having a bow-shaped design per connection point. This way, the single connection profile can be made very compact and the connection profiles between the connection profiles are arranged individually.

Further measures improving the invention will be described in more detail below together with the description of preferred embodiments of the invention with reference to FIGS.

Detailed description of the drawings

In Fig. 1 is a sectional view of the composite profile according to the invention according to a first embodiment to see. This consists of the two metallic connection profiles 1a and 1b, which are connected to the intermediate connection profile 2. For this purpose, the connection profile 2 has four bow-shaped formations 3a-3d, each with an elastically resilient leg 4a-4d, which are clipped into corresponding recesses 5a-5d of the connection profiles 1a and 1b. When clipping the legs 4a-4d perform under elastic deformation a movement in the direction of the respective shaft 6a-6d of the bow-shaped training 3a-3d and finally hook in the assembled state in Hinterhakungsmöglichkeiten 7a-7d of the recesses 5a-5d, so that a form-fitting Connection between the connection profile 1a and the connection profile 2, as well as between the connection profile 1b and the connection profile 2 is made. In order to prevent migration of the connection profile 2 in addition, it is possible to introduce an adhesive or similar curing material in the interior of the bow-shaped formations 3a-3d. In addition, the connection profiles 1a and 1b in the region of the recesses 5a-5d each have cavities 8a-8d, which ensure that the material at this point during insertion of the bow-shaped formations 3a-3d gives something and triggers a spring effect, whereby in the mounted state the connection profile 2 constantly presses to form a positive connection for preventing axial movement between the connection profiles 1 a and 1 b and the connection profile 2. In addition, the connection profiles 1a and 1b in this area, as in Figure 4 shown, a rib-like profiling 9, to further improve the adhesion. In order to prevent axial movements even in the high force range between the connection bars 1a and 1b and the connection profile 2, as shown in detail in FIG Figure 3 shown, both the respective connection profile 1a or 1b and the connection profile 2 along a contact line via corresponding toothings 7 and 8.

In Fig.2 a second embodiment of the composite profile according to the invention is shown. In contrast to the previously described embodiment, in this case the connection profiles 1a and 1b are connected to each other via two individual connection profiles 2a and 2b connected. In this case, the connection profiles 2a and 2b respectively have a bow-shaped formation 3a-3d which faces the respective connection profile 1a and 1b and which, as already described above, are clipped into corresponding recesses 5a-5d with an elastically resilient leg 4a-4d.

In Figure 5 is a perspective sectional view of the composite profile according to the invention according to a third embodiment in the region of a connection point between a connection profile 1 'and a connection profile 2' to see. In contrast to the previously described embodiments, when clipping in this case, the shaft 6 'of the bow-shaped formation 3' undergoes an elastic deformation by a tilting movement and subsequently hooks with the corresponding leg 4a 'or 4b' into the hooking possibility 7 'of the recess 5'. one. Due to the space in the recess 5 'and according to the placement of Hinterhakungsmöglichkeit 7', which, as from Figure 6 can be seen, is mutually arranged, the shaft 6 'remains in an elastically deflected form. In the axial direction of the connection profile 2 ', this deflection corresponds to the shape of the placement of the hooking possibility 7' and in this case has a wave-shaped course. Out Figure 7 is the shaft 6 'of the connection profile 2' in the uninstalled state, that is not shown elastically deflected.

The embodiments described above are preferably intended for facade systems with windows and doors, but not limited to these. Rather, the systems described can also be used in metal construction systems where thermal insulation has to be accomplished in any way.
