Description

The present invention relates to a frame or a T-joint, in particular a window frame or a door frame, with a sealing profile which is fixed with a foot part to a frame profile, wherein the sealing profile is arranged in a central region of the frame profile, as well as a Method for mounting a frame or T-joint.

The EP 1 712 723 discloses a frame for a window or a door, is provided in the middle region in sealing profile of a solid material, ie without hollow chambers. The sealing profile is guided in the corner region of the frame via a corner element, which has an arcuate portion in order to avoid a strong buckling of the sealing profile. Although this guidance of the sealing profile allows an arcuate course that interferes with the closing of a window or door leaf and can be easily damaged. In addition, the height of the sealing profile is limited, since the window sash must be movable within the bent portion of the sealing profile.

Also at the EP 1 972 749 a frame profile is shown, in which a sealing profile is arranged in a central region of the frame and bent in the corner region. The bent portion is comparatively strong in the interior of the corner and therefore requires large gaps to the wing.

It is therefore an object of the present invention to provide a frame or a T-joint and a method for mounting a frame or a T-joint, which allow an improved installation of the sealing profile in the corner and provide high thermal insulation.

This object is achieved with a frame or a T-connection with the features of claim 1 and a method for mounting a frame or a T-connection with the features of claim 12.

According to the invention, the sealing profile is cut in a corner region of the frame or the T-connection on the outside and aligned at an angle. Thereby, the sealing profile can be bent in a much smaller radius, so that in the corner region protruding of the sealing profile is avoided by a weakly rounded portion. In addition, the sealing profile can be aligned in exact position over the incision in the corner area and strong material stresses in the bending area can be avoided.

According to a preferred embodiment of the invention, a corner element is arranged on the incision of the sealing profile. The corner member may serve to align the angularly oriented sealing profile and allow prefixing of the sealing profile in the aligned position.

The sealing profile is preferably formed as a hollow chamber profile, in particular of an elastic material. The hollow chambers can occupy at least 40%, in particular at least 50% of the volume of the sealing profile. The sealing profile preferably has an outer wall with the foot part and an inner wall, on which a sealing projection is formed, wherein the outer wall and the inner wall are connected to each other via a plurality of intermediate walls. The inner wall and the outer wall as well as the intermediate walls are each gulled on their surfaces, so that a cutting over a part of the intermediate walls is possible without further damaging the sealing profile. In this case, an incision can be made, which extends through an outer wall and at least partially through a region of the intermediate walls, preferably the intermediate walls are completely severed, so that a simple bending of the sealing profile in the corner area is made possible.

Preferably, the corner element has at least one channel for distributing sealing compound. The channel may then have one or more distribution sections to seal the areas where two frame profiles abut each other, such as the miter surface of two frame profiles or the abutment surface.

For ease of assembly, the corner element is at least partially made of an elastic material and can be latched to webs of the frame profile. The corner element can be latched to two adjacent frame profiles in the corner area, so that it is held exactly in the corner area.

For a good prefixing of the sealing profile in the corner region, the corner element may have projections which can be inserted into hollow chambers of the sealing profile. As a result, the sealing profile can also be preassembled outside the frame profiles on the corner element and then fixed together with the corner element in the corner region. Of course, it is also possible to first fix the corner element in the corner region of a frame or a T-joint, and then fix the sealing profile to the corner element, wherein the projections allow easy checking whether the sealing profile has been correctly mounted on the corner element.

The corner element may in this case essentially have a cuboid web on which the projections for fixing the sealing profile are formed, wherein in the cuboid web at least one channel for distributing sealing compound is formed, which is perpendicular to the plane of a filling element in the frame or the T. Connection extends.

For easy installation, the sealing profile is provided circumferentially on a frame. In this case, the two front ends of the sealing profile abut each other in abutment, which still leads to sufficient sealing properties. In this case, four corner elements may be provided on a frame, by means of which an integral sealing profile is aligned.

For mounting a corresponding frame or T-joint, first a sealing profile is cut on an outer wall and then bent at the cut portion to align it at an angle. A corner member is then inserted into the cut portion to mount the seal profile to a frame profile of the frame or a T-joint. Thereby, the sealing profile can be formed continuously in the corner without the sealing profile protruding too far into the interior.

For a simple installation of the corner element this can be locked to one or two frame profiles in the corner. After assembly of the corner element, a sealant can then be injected into a channel in the corner element in order to seal the corner area in an optimized manner.
