Description

The invention relates to a frame profile and a frame according to the preambles of the independent claims.

Frame profiles made of metal or plastic form in many areas of technology essential building components, such as in building construction, especially in facade construction. Here prefabricated or standardized frame profiles are manufactured in the industry and then delivered directly on site, where they are installed by the fitter on site individually in the building. In addition, the frame profiles are already combined in industry to form building components, such as window frames or door frames, and then delivered on site and assembled on site by the fitter on the building or on the façade.

Due to the high price requirements in the construction industry, the manufacturer of frame profiles must take care that the material costs of the frame profile are kept low. Although savings in the material lead to a significant reduction in manufacturing costs, care must be taken at the same time that there are no unnecessary delays in the construction of the building or during assembly of the building components on the building.

The EP 1 441 096 B1 shows an attachment of a fitting part to a profile bar as a frame profile of a window or a door. The profile bar has a profile groove in which a clamping part can be inserted. The clamping part consists of four components, namely two identical pressure parts and two identical pressure pieces. Using the clamping part and the four components, the fitting part is clamped to the profile bar with screws.

A disadvantage of this known solution is that the attachment of the fitting part comprises several components and therefore the attachment of the fitting for the mechanic is very complicated, whereby the assembly costs are more expensive.

The EP 0 087 504 A1 discloses a U-shaped metal profile as a frame profile consisting of two legs which are connected to a base, wherein the metal profile has a continuous material thickness. In the U-shaped metal profile, a plate is arranged, which is fixed with screw bodies and nuts in the U-shaped metal profile. In this case, one of the legs has a projecting into the U-shaped metal profile mounting bead, in which a nut is fixed, on which a fitting can be arranged with a screw body.

A disadvantage of this known solution is that the mounting bead is used only for countersinking the nut and for fastening a fitting in addition to the screw body and a nut is needed.

It is the object of the present invention to overcome one or more disadvantages of the prior art. In particular, a frame profile is to be created, to which components, in particular fittings, can be easily fixed by the installer, the components are time-saving mountable in a few steps.

The object is solved by the features of the independent claims. Advantageous developments are set forth in the figures and in the dependent claims.

The inventive frame profile consisting of a band and a band at least partially limited cavity, with at least one mounting bead for attaching a component to the frame profile, wherein the frame profile in at least a first portion of the band has a first material thickness and the at least one mounting bead a Befestigungsmittelsicke for receiving a fastening means, wherein the fastener centering protrudes at least partially into the cavity. The band has a further portion with a further material thickness, wherein this further material thickness is reduced compared to the first material thickness and the fastener center bead is arranged in this further portion of the band.

The fastening means bead described here is designed to receive a fastening means, typically a screw, and to engage with the fastening means in a frictional or positive connection. In this case, the fastening means with the band in the fastener center bead can be screwed directly, without the fastener is excessively deformed or such a high force must be applied, that this is not possible without expensive equipment. Such configured fastener bead allows precise positioning of a component on the frame profile, without the frame profile must be pre-drilled. Typically, a thread-forming or thread-forming screw, for example a self-drilling screw, is used, which can be inserted into an opening provided in the component for the fastening means and the component is fastened or clamped to the fastener center bead on the frame profile. In this case, the thread-forming or thread-forming screw cuts in sections through the fastener center, whereby a positive connection with the frame profile is generated. A described as described arrangement of the fastener bead with a reduced material thickness in the frame profile or in a window frame profile or in a door frame profile surprisingly allows the assembly of the component, in particular the mounting of a fitting on the frame profile in a single step, the fastener penetrates the fastener center and simultaneously the component or the fitting fixed to the frame profile.

A belt described herein is a sheet material, typically a sheet of sheet, having a width of material which is wider than its material thickness and shorter than the length of its material.

Under a mounting bead is understood in the present case, a groove-like depression in a flat or a curved surface of a component, wherein the depth of the recess with respect to the length of the recess is small. Typically, mounting beads serve for countersinking fasteners or for positively connecting the frame profile to a component.

Advantageously, the frame profile in the vicinity of the mounting bead on a first material thickness, whereby in this section a basic stability is ensured in the frame profile.

Preferably, the further material thickness is 0.07 times to 0.55 times the first material thickness, whereby a material-saving production of the fastener center bead is made possible.

Preferably, the further material thickness is 0.33 times the first material thickness. Thus, depending on the material of the band and the further material thickness in the further section, a cost-effective fastening means can be selected which can be screwed directly into the fastening medium bead without the fastener being subjected to extraordinarily high loads.

Preferably, the further portion of the band is arranged between the at least one first portion of the band and a further first portion of the band, wherein the first portion and the further first portion each have the first material thickness. This ensures high stability in the frame profile and at the same time allows easy attachment of the component to the frame profile.

Preferably, the fastener bead has a closed bead bottom, whereby the creation of the fastener bead in a single step can be done in a time-saving manner.

Preferably, the closed bead bottom is formed by a bead bottom rounding for guiding the fastening means, whereby the component or the fitting can be positioned precisely on the frame profile.

Preferably, the bead bottom rounding has a radius of curvature between 0.1 mm and 1.2 mm, whereby fastening means are guided with various embodiments of the fastening means during fixing. The common fasteners used here have curves on the body, which simply fit into the Sickbodenrundung.

In particular, the bead bottom rounding has a radius of curvature between 0.25 mm and 0.8 mm, whereby a mispositioning of the fastening means on the frame profile can be minimized and a renewed positioning of the component or of the fitting is avoided.

Preferably, the bead bottom rounding has a radius of curvature of 0.5 mm, whereby an exact positioning of the component or the fitting on the frame profile is made possible and thus a costly repositioning of the component or the fitting is excluded.

Preferably, the fastener center has an opening angle, wherein the opening angle is 20 ° to 150 °. This improves the guiding properties of the fastener bead when attaching the component to the frame profile with the fastening means, whereby the fastening means or the fitting is easy to assemble.

In particular, the opening angle of the fastener center bead is 40 ° to 100 °. As a result, tilting of the fastening means when fastening the component or the fitting to the frame profile is minimized.

The opening angle of the fastener center bead is preferably 60 °, as a result of which the fastening means can be applied easily and precisely, engages in the frame profile and is thus optimally placeable.

Preferably, at least one groove is provided, wherein the fastener center bead is disposed within the at least one groove. The groove has a first groove leg and a second groove leg which are connected by a groove base, wherein the fastener groove is preferably arranged on the groove base. The component or the fitting is typically partially applied to the groove or is placed in the groove and is guided or held in it or even stable.

In particular, the at least one groove is a EURO groove, wherein the fastener center bead is arranged within the at least one EURO groove. A EURO-groove is an industry-standard groove for fitting fittings to frame profiles. Thus, components with standard masses can be fastened to the frame profile and fixed to the fastening medium bead by means of fastening means.

Preferably, the groove has a first connecting leg and a second connecting leg, wherein the first connecting leg and the second connecting leg connects the fastener center bead with the groove base. In this case, the component or the fitting in the groove is stably positionable and the fastening means in the first connecting leg and in the second connecting leg additionally fixable, whereby an improved attachment of the component or the fitting takes place.

Preferably, the groove is arranged at least at a fold of the band. Thus, the stability of the frame profile is improved despite the arranged groove, so that an undesirable deformation of the frame profile is avoided during component mounting.

In particular, the fold is applied to an area of the band, whereby the groove is arranged stably in the frame profile.

Preferably, the band is made of metal, whereby the frame profile has an increased stability to softer materials, such as typically plastic, and is versatile.

Preferably, the band is made of steel, whereby the frame profile has a particularly high stability and can be easily machined.

Another aspect of the invention relates to a frame, in particular a window frame or a door frame with a plurality of frame profiles, wherein at least one of these frame profiles is designed as a frame profile as described herein. As a result, a component or a fitting can be screwed directly to at least one frame profile, whereby the fitter can easily assemble the frame on site.

• - Reduzieren der ersten Materialdicke in einem Abschnitt entlang des Bandes;
• - Formen der Befestigungsmittelsicke in diesem Abschnitt mit der reduzierten weiteren Materialdicke.

A further aspect relates to a method for producing a frame profile as described herein, wherein a fastener center bead is produced at least by the following steps:

• - Providing a band with a first material thickness;
• Reducing the first material thickness in a section along the belt;
• - Forming the fastener grove in this section with the reduced further material thickness.

With this method, the frame profile described herein with a fastener center can be easily and inexpensively manufactured, wherein the reduction in thickness in the section along the belt leads to low internal stresses and strong distortions of the belt. As a result, the fastener center bead can subsequently be formed without substantial material hardening occurring in the section with reduced material thickness, so that a direct screwing of a fastener into the fastener center bead is made possible in a simple manner.

Preferably, the further material thickness is reduced in the section along the belt by a rolling process. With a rolling process, the reduction of the further material thickness in the section along the belt can be carried out inexpensively, whereby the internal stresses in the section with reduced material thickness can be minimized. In addition, a rolling process allows the economical production of large quantities. The rolling process on the belt is carried out in a typical rolling device with at least two rotatable rollers, which are arranged opposite one another. Reducing the first material thickness in the section along the strip in the rolling process typically displaces the excess material portion. Preferably, a rollshaping method is used for this purpose.

Preferably, reducing the first material thickness in a section along the belt takes place simultaneously with the formation of a preform of the frame profile, which enables a particularly economical production.

Advantageously, the forming of the fastener bead is accomplished by means of a counter-mold and profiled rollers which are guided in the section of reduced further material thickness and press the reduced-thickness section into the counter-mold, thereby forming the fastener-center bead. As a result, the fastener bead can be formed particularly easily and cost-effectively along the entire section with reduced material thickness.

Alternatively, reducing the first material thickness in a section along the belt is done by a drawing process. This is typically used a deep drawing process, wherein the reduction of the further material thickness can be easily adjusted.

Advantageously, the forming of the fastener bead in the section with the reduced further material thickness takes place simultaneously in the drawing process. This can be done in one step, the reduction of the further material thickness and the forming of the fastener grove, resulting in a considerable time savings in the production of the frame profile.
