Description

The present invention relates to a frame part for a frame, which is intended for installation in an opening of a wall, wherein the frame part has a hollow profile and at least one reinforcement, wherein the hollow profile has at least one continuous main hollow chamber extending in the longitudinal direction of the hollow profile, wherein the Arming is included in the main hollow chamber. The present invention further relates to a method for producing a frame part comprising a hollow profile and a reinforcement for a frame, which is intended for installation in an opening of a wall.

Frames, which are intended for installation in an opening of a wall, in particular window frames of plastic windows or plastic window systems, are subject to the increased requirements for improved thermal insulation or for improved or optimized thermal insulation. To provide the required statics and strength of the window frame, the individual frame parts of the frame reinforcements, which are preferably made of steel and are accommodated in a main hollow chamber of the hollow profile.

Due to the high thermal conductivity of the existing usually steel or other metallic material reinforcements, however, these are disadvantageous for the thermal insulation or thermal insulation, but still required for the provision of the required statics or strength. In the prior art known frame parts for frames, in particular for window frames, therefore, in addition to a main hollow chamber, a plurality of further hollow chambers, which are to reduce heat transfer. By providing the further hollow chambers, compensation for the deterioration of the thermal insulation properties caused by the reinforcement can be provided to some extent. It is also known to provide thermally separated reinforcements in a frame part. However, the provision of the further hollow chambers has the consequence that the frame part is not reinforced by a reinforcement at least in regions of the further hollow chambers, so that while acceptable thermal insulation properties are present, the rigidity or strength of the frame parts and thus of the frame is formed much smaller than in known solutions with a comparatively wide main hollow chamber and a comparatively wide reinforcement, which is accommodated in this main hollow chamber.

Underlying task

The present invention has for its object to provide a frame part for a frame and a method for its production, which in contrast to known solutions has a sufficiently high stability or strength, also in conjunction with good thermal insulation properties.

Inventive solution

This object is achieved with a frame part for a frame with the features of claim 1 and a method with the features of claim 6.

In contrast to known solutions, the invention provides that in the main hollow chamber at least one provided on the reinforcement thermal insulation element is disposed of thermal insulation material.

By providing the insulation element of thermal insulation material on the reinforcement, if the frame and thus also the frame part of the frame is installed in the opening of the wall, in particular a heat transfer caused by heat conduction or a heat transfer caused by heat conduction through the frame part, in particular in a thickness direction the wall can be significantly reduced.

In contrast to known solutions, by providing the insulating element, it is advantageously possible to dispense with further hollow chambers for improving the thermal insulation properties, so that the frame part is e.g. can be provided with a wide main hollow chamber and a wide armor received in this main hollow chamber, along with a high strength or stability of the frame part. The insulation element provided according to the invention enables effective compensation for the impairment of the thermal insulation properties possibly caused by the reinforcement. Due to the possible omission of further hollow chambers, the production costs for the frame part can be significantly reduced, in particular, in comparison to known solutions.

In a preferred embodiment, the insulating element is held by clamping on the reinforcement, which may preferably consist of a metallic material or steel. In this way, the insulating element can advantageously be arranged or provided in a stationary or immovable manner on the reinforcement or in the main hollow chamber.

In a particularly preferred embodiment, the insulation element is integrally connected to the reinforcement, in particular adhesively bonded to the reinforcement. In this way, a heat transfer can be very effectively reduced by the frame part, in particular due to a conduction of heat through the reinforcement. In this embodiment, the insulating element is a materially bonded to the reinforcement element with a high thermal resistance or a high specific thermal resistance or with a low thermal conductivity or a low specific thermal conductivity, which severely restricts further heat conduction, so that in particular in the thickness direction the wall of the heat transfer is very effectively reduced when the frame and thus the frame part of the frame is installed in the opening of the wall.

The thermal insulation material is particularly preferably a polymeric foam material which, owing to its high thermal resistance or its low thermal conductivity, can very effectively contribute to reducing the heat transfer or to improving the thermal insulation properties.

In a practical embodiment, the insulating element extends over at least 0.2 times, preferably at least 0.3 times and more preferably at least 0.4 times the dimension of the main hollow chamber in a thickness direction of the wall when the frame is installed in the opening. Such an extension of the insulating member in the thickness direction of the wall very effectively reduces in the thickness direction, in particular, a heat transfer by heat conduction, accompanied by a marked improvement in heat insulating properties.

The hollow profile is preferably an extruded hollow profile. Furthermore, the hollow profile preferably consists at least partially or completely of a polymer material. The polymeric material may e.g. in particular polyvinyl chloride (PVC).

• (A) providing a hollow profile with at least one contiguous main hollow chamber extending in the longitudinal direction of the hollow profile and providing a reinforcement,
• (B) providing an insulating element of thermal insulation material, and
• (C) insertion of the reinforcement and the insulation element in the main hollow chamber.

In this way, a solid, preferably planar connection or a planar contact of the reinforcement to the hollow profile can be created, which is associated with a good force transferability of the hollow profile on the reinforcement and substantially increases the strength or rigidity of the frame member. From a proposed in known solutions consuming attaching the reinforcement to the hollow profile by means of screws or rivets, as provided in particular for window frames for plastic windows, can be dispensed with according to the invention.

In particular, of punctiform connections of the reinforcement with the hollow profile, which are present in the known solutions by means of screws or rivets, can be dispensed with according to the invention. In the known solutions, these punctiform connections are associated with poor force transferability from the hollow profile to the reinforcement, resulting in adverse power transmission losses, along with a deterioration in strength or rigidity.

The polymeric foam material may preferably be a polyurethane foam or a polyurethane foam material, which is advantageously distinguished by a high thermal resistance or a low thermal conductivity.

Alternatively, the foaming process may be activated after joining the insulating member to the armor prior to step (C), wherein the insertion of the armor and the insulating member into the main hollow chamber is e.g. during the foaming process or during the ongoing foaming process can be made. However, the insertion of the reinforcement and the insulation element into the main hollow chamber can also be carried out only after the foaming process or after completion of the foaming process.
