Description

Frames for windows, doors or facade units

The invention relates to a frame for a window, door or facade unit according to the preamble of claim 1 .

In addition to window frames and casements with a common appearance, so-called panel windows are also known, which are included in the present invention.

In a window, door or facade unit made as a panel window, the frame has an external casement stop which completely or almost completely covers the casement frame on the outside of the window so that it is ideally no longer visible from the outside .

Figure 3 shows an example of a panel window of this type, the internal state of the art of the patent applicant. Indicates an insulating profile consisting of a metal profile shell, which forms the frame and sash and is connected by spacer strips. The spacer strips form an insulating plane between the profile shells, and they limit the heat flow from one profile shell to the other to a minimum. The material of the spacer is therefore a poor conductor of heat and usually consists of plastic.

Profiles joined by spacers are referred to hereafter as composite profiles. The advantage of such a composite profile with a shear-resistant connection is a higher strength compared to the individual elements—thereby a better static behavior. When calculating the static properties of the composite profile, the different materials or strengths of the composite individual elements are taken into account by reduction factors in the calculation formula.

The frame of the window, door or façade unit is either formed as an external closing device for a wall or other element or is equipped with a second stop for the external sloping front ribs (Laibungssteg). Alternatively, the frame can also be provided with a plug-in cam which engages with a corresponding plug-in recess of an adjacent component. The panel window of FIG. 3 according to the prior art has a frame of this type.

The frame of the panel window in FIG. 3 is designed as a pluggable element connection (also called plug-in profile), wherein it can compensate for thermal expansion and is often used in house facades. Pluggable frame profiles or associated plug-in profiles are usually not connected with screws.

In order to obtain a smooth transition from one profile to another in a frame of plug-in profiles, it is proposed that the inner and outer profiles of the frame each have outer arms, which are, for example, stepped (see planes A and B), wherein the profile arms At the junction with the steps, there are sections facing away from the door frame and pointing outwards, they are close to each other, and constitute the inner wall of the plug-in boss in the plane of the glass or the front of the house. Although the closely adjacent profile arms are connected to each other by spacer strips, the thermal insulation effect of the frame is reduced in this region due to the greater heat transfer between the closely adjacent profile arms.

Secondly, in order to ensure sufficient compensation of expansions caused by temperature changes and to ensure good guidance requirements, the profile arms of the frame are made relatively long in the area of the bosses compared to the remaining dimensions of the frame. However, in order to ensure a sufficiently good static behavior of the frame in the area of the bosses, the profile arms have a greater wall thickness.

It is therefore the object of the present invention to improve a window, door or facade unit of this type in such a way that the material requirements for the metal used to manufacture the frame as the insert profile are reduced and improved with respect to the prior art. Thermal insulation in the boss area of the frame.

The invention achieves this object by the subject matter of claim 1 . Therefore according to the present invention it is envisaged that at least one fastening region and root region of the spacer strip of the frame plug-in boss are arranged on the frame inner and outer profiles offset from each other in the plane of the door, window or house facade. This measure allows the arms of the inner and outer profiles of the frame to be significantly shortened or completely omitted in the region of the plug-in cams. The spacer strip thus assumes almost the task of the upper profile arm of the inner profile. The metal material required to make the frame is reduced and thermal insulation is improved, as metal, which conducts heat well, is replaced by plastic, which is a poor conductor of heat for the spacers.

The profile according to the invention achieves particularly good static properties if the spacer strips forming the outer walls of the plug-in bosses have cavities, in particular cavities provided with reinforcement crosspieces.

According to another idea of the present invention, at least one spacer strip arranged between the inner profile and the outer profile gradually tapers from the inner profile to the outer profile, preferably in such a way that the tapered spacer strip of the leaf frame is inside The profile has a wider root region than the outer profile. This structurally simple solution makes it surprisingly possible to use profiles with narrow frontal widths even with relatively large window sizes.

Further advantageous developments of the invention can be obtained from the remaining subclaims.

The present invention will be described in more detail below by means of an embodiment with reference to the accompanying drawings. They mean:

Fig. 1 is by the section of the frame of panel window of the present invention;

Figure 2 The frame in Figure 1;

FIG. 3 is a cross-section through a frame of a panel window according to the prior art.

According to FIG. 1, the composite frame 1 of the panel window has an aluminum inner profile 3 and an aluminum outer profile 5, which are passed through two heat-insulating strips or insulating strips, which are arranged parallel to each other and consist of poor heat-conducting materials, especially plastics. 7, 9 are fixedly connected to each other. A stop rib 11 is formed on the outer profile 5 perpendicular to the main direction of extension of the frame 1 (or parallel to the glass plane), which completely or almost completely covers the door frame 13 on the outside of the window so that the door frame cannot be seen from the outside.

The composite door frame 13 itself has an aluminum inner profile 15 and an aluminum outer profile 17 smaller than the inner profile (note: the inner and outer profiles of the frame and the door frame are also called the inner shell and the outer shell), wherein the inner profile 15 is fixedly connected to outer profile 17 via a single spacer strip 19, which likewise consists of a plastic with poor thermal conductivity. An inner seal 21 , an outer seal 23 and a strip 25 complete the glazing rebate for the glass pane 27 .

Because the spacer strip 19 arranged between the inner and outer profiles 15, 17 of the door frame 13 tapers from the inner profile to the outer profile, it is possible to achieve a width that is particularly narrow in appearance but allows relatively large elements due to good static properties (Window) Dimensions of the outer profile. Good static values are obtained in particular through the possibility of designing the root region of the spacer strip, which engages groove-like in the groove 31 on the inner shell, relatively large. Due to the tapering of the spacer strips 19 the root region 29 at the inner profile 15 is made wider than the root region 33 embedded in a corresponding groove 35 on the outer profile 17 . The tapered structure of the spacer strips 19 results from rolling on different levels. Furthermore, the tapered structure of the spacer strip 19 facilitates the distribution of forces when counteracting the force of gravity and the resulting moments.

Next, generate a rib 36 that stretches into the groove between the frame and the door frame 1,13 in the root region 33 of the spacer 19 or its top wall near the shell 17, and it extends beyond the boundary of the door frame outer profile 17. In the groove between the frame and the door frame. Together with the intermediate seal 37 , this rib 36 delimits the front chamber 39 from the fitting chamber 41 . Next, as can be seen from FIG. 1 , the spacer strip 19 of the door frame 13 extends beyond the boundary of the profile 15 in the door frame into the groove or fitting cavity 41 . This advantageously additionally protects possible locking elements in the fitting chamber 41 from being destroyed from the outside or from excessive force.

Next, as can be seen in Figure 2, the frame is equipped with a plug-in boss 43, wherein the spacer strip 9 constitutes a statically important part of the frame plug-in boss, and is only covered by an arm 45 of the outer profile of the frame 1 on the outside of the frame 1 , so it cannot be seen from the outside. However, the spacer strip 9 towards the inside takes over the static tasks that would otherwise be performed by the protruding arms of the inner profile. For this reason, the fixing regions and the root regions 47, 49 of the spacer strips 9 of the plug-in bosses of the frame 1 on the inner and outer profiles 3, 5 of the frame 1 and the root regions 47, 49 are arranged staggered relative to each other along the direction of extension E of the window.

To increase the strength, the spacer has a plurality of cavities 51 through which additional reinforcement crosspieces 53 are distributed. Secondly, the spacer 9 of the insertion boss has a first basic rib 55, integrally formed on it towards the root region 47 of the inner profile 3, and also has a second basic rib 57 parallel to the first basic rib 65, on which A root region 49 facing the outer profile 5 is integrally formed on the upper side and has at least two transverse ribs 59 running substantially perpendicular to the base ribs, which connect the first and second base ribs 55 , 57 to one another. The spacer strip 9 is additionally supported on the outer profile 5 by means of a supporting lug 61 integrally formed on the first basic rib 55 , so that a static triangle is formed by the further walls 53 and 55 as well as the rib 45 and the supporting lug 61 .
