Description

The invention relates to a method for connecting two hollow profiles made of plastic in the miter area, wherein the two hollow chamber profiles have the same depth, but different view widths.

Technical area

Hollow-chamber profiles made of plastic are widely used for the production of windows and doors. One of the main advantages of this material is the weldability in the miter area. Usually hollow plastic profiles are therefore cut to length in the miter area at 45 ° and welded together, the individual hollow chambers, especially the steel chambers, are sealed together.

For aesthetic reasons, profiles with as narrow a view width as possible are often preferred for window sashes. For lockable doors for doors, in particular for so-called side entrance doors, e.g. used for basements, terraces and balconies, the use of profiles with a larger face width is necessary because of the lock box to be used. Especially with wooden sculptures, profiles with a narrow face width can be combined on three sides with a profile with a larger face width for the lock box side.

State of the art

From the DE 197 43 489 C1 a connector for wooden sash is known, which connects two dull cut profiles in the corner. Basically, such corner connectors for wood profiles are also such conceivable that in the corner narrow and wider wing profiles can be connected together. So could also be made doors that are connected to three Side wooden profiles with narrow view width and on the lock side have a profile with wider view width.

A corner connector according to the DE 197 43 489 C1 would interfere with plastic profiles, however, because of visible even with the wing closed areas of the corner connector.

task

The object of the present invention is therefore to provide a method for connecting two hollow chamber profiles, in particular sash profiles, made of plastic in the miter area, wherein the hollow chamber profiles to be joined have the same construction depths but different face widths and wherein the two hollow chamber profiles each on one side , usually on the inside, have a rollover and a wall forming the visible surface of this side and covering the rollover.

Presentation of the invention

The invention solves this object by a method according to claim 1, preferably in conjunction with one or more of the features of claims 2 to 8. claim 9 relates to a preferred use of this method.

The core of the present invention lies in initially cutting off or trimming the hollow-chamber profiles with different view widths, as usual, in the miter area, and to weld them together and to weld them together in the miter area. Subsequently, with machining, in particular by milling, a portion of the welded corner removed, wherein the rollover overlapping wall remains as so-called overlap. The milled miter area is then covered by an end cap.

According to a first embodiment of the invention, a part of the miter surface of the hollow chamber profile with the larger view width is after the welding of the hollow chamber profiles. This in the view triangular projection can be removed during the machining of the miter profiles welded together in the miter area. In principle, however, it is also possible to remove this triangular region, for example, by a saw cut perpendicular to the longitudinal extension of the wider hollow chamber profile, even before welding the hollow chamber profiles. Furthermore, it is possible to first cut the wider hollow chamber profile by a running perpendicular to the longitudinal extent of the hollow chamber section section to the required length and to produce the miter surface by a second performed at 45 ° section.

According to a preferred embodiment of the invention, the end cap is designed so that the outer contours of the two hollow chamber profiles including the flashovers are continued. Preferably, the end cap on a Dichtungsaufnahmenut, which continue the Dichtungsaufnahmenuten the flashovers of the hollow chamber profiles each. In this embodiment of the invention is not - as usual - a cohesively connected in the PCE method with the hollow chamber profiles inner stop seal used, but following the manufacture of the invention, a seal having a sealing foot, is rolled into the circumferential seal receiving groove. In principle, it is also possible to work in partial areas with an extruded or PCE seal and in the area of the end cap with a rolled-up seal.

According to a particularly preferred embodiment of the invention, the machining of the hollow chamber profiles welded together in the miter area takes place in such a way that the outer walls of both hollow chamber profiles form a narrow outer overlap, which projects beyond the profile area projecting behind it.

As far as the terms "inside" and "outside" or "inner" and "outer" are used in this description and in the claims, this refers to the usual case of an inward one opening wing. Of course, the method according to the invention can also be used with outwardly opening wings, it is then in the rollover not the inner, but the outer rollover, etc. The rollover serves in both cases as a stop of the wing to the frame.

The machining of the hollow chamber profiles welded together in the miter area preferably takes place by means of a milling cutter, the milling cutter being guided parallel to the longitudinal extent of the narrower hollow chamber profile. In this embodiment of the invention, the end cap on a circular segment-shaped portion corresponding to the milling.

In a preferred embodiment of the invention, the two side surfaces of the end cap jump back by a few 1/10 mm. In these areas, additional adhesive is advantageously applied prior to assembly, so that after assembly, the side surfaces of the end cap are glued to the overlays. As a result, an additional seal and a higher corner strength are achieved. The end cap can alternatively or advantageously be additionally connected by screws with the hollow chamber profiles.

The inventive method is particularly suitable for the production of doors with lock case, in particular so-called side entrance doors, as they are used for basements, terraces or balconies. In particular, the invention is advantageously used for sculptures, and in particular for the so-called. Walking wing, so the first opening wing.

Best way to carry out the invention

In the embodiment shown below, an inwardly opening side entrance door of three narrow hollow sections 1 with a depth 4 of 76 mm and a face width 6 on the inside of 39 mm and - seen from the room inside - right arranged wider hollow section 2, which also has a depth 5 of 76 mm, but having a face width 7 on the inside of 79 mm. All profiles were PVC-u. The illustrated system is a center seal system.

In Fig. 1 is a side entrance door according to the invention including frame 40 (frame) in the view from inside and in Fig. 2 in the outside view as well as in Fig. 3 shown as horizontal section AA. The narrower hollow chamber profile 1 is stiffened with a steel reinforcement 25 and the wider hollow chamber profile 2 with a steel reinforcement 26. The flashovers 10, 11 cover - as usual - the frame 40 and are on the inner stop seal on this.

For producing the secondary entrance door according to the invention, the hollow chamber profiles 1, 2 are first cut to length at an angle of 45 ° and, as in FIG Fig. 4 and 5 to recognize, welded together in the miter 3. The weld 20 accordingly also runs at an angle of 45 ° to the longitudinal extent. The wider hollow chamber profile 2 forms a triangular projection 16 in the corner region, which is removed during the subsequent milling process.

In Fig. 4 the lower right corner area is already milled out, while the upper right corner area still needs to be milled. The milling takes place by means of a three-segment circular milling cutter whose axis of rotation is perpendicular to the glazing plane and thus perpendicular to the inner visible surface 12, 13.

The cutter is guided parallel to the longitudinal extent of the upper or lower horizontally extending narrow hollow chamber profile 1, so that a recessed profile region 34 is formed with a circular arc expiring Fräsbild. The router has room inside a deep and space outside a small gradation, so that while milling the supernatant 16 removed, but the walls 14, 15 of the hollow chamber profiles 1 and 2 remain. These walls 14, 15 form the overlay 17 (FIG. Fig. 8 ). On the outside, after milling, the outer walls 31, 32 are also opposite the recessed profile area 34 by a few mm and thereby form the narrow outer overlay 33 (FIG. Fig. 7 ).

In Fig. 5 the wing after welding, but before milling in the plan view of the insides 8, 9 is shown. The face width 6 of the narrower hollow chamber profile 1 and the face width 7 of the wider hollow chamber profile 2, as in Fig. 3 and 5 are shown, each refer to the interior without glazing bead. In Fig. 5 the grip plate 37 is drawn in to indicate the position of the lock case in the wider hollow chamber profile 2.

In Fig. 6 is the miter 3 of the welded, but not yet milled hollow chamber profiles 1, 2 shown in a perspective view. In Fig. 6 In particular, the flashovers 10 of the hollow chamber profiles 1 and 2 and the outer wall 32 of the hollow chamber profile 2 can be seen.

In the Fig. 9 to 11 the end cap 18 used according to the invention with the sealing pad 23 is shown in various perspective views. The end cap 18 was made by injection molding of thermoplastic material. The sealing pad 23 made of sponge rubber is placed on the arcuate expiring bottom of the end cap 18, but can also be glued to this if necessary. The sealing pad 23 serves to seal the open ends of the hollow chambers 22 and in particular of the steel chambers 27, 28. The contour of the underside of the end cap 18 corresponds exactly to the milling contour in the miter area 3 of the hollow chamber profiles 1, 2 (FIG. Fig. 8 ).

The mounting of the end cap 18 in the miter 3 is in the 15 to 17 shown the end cap 18 is first inserted after attaching the sealing pad 23 with the two front pin 39 in the open hollow chambers 22 of the narrow hollow section 1 and then pivoted with a slight rotational movement on the milled face of the wider hollow chamber profile 2, wherein the pins 21, 21st ', 21 "and 21'" in the open ends of the hollow chambers 22 of the hollow chamber profile 2 dive. Finally, two screws 24 are screwed. The pin 21 " serves at the same time the leadership and support of the screw 24th

In the illustrated embodiment, the two side surfaces 41, 41 'of the end cap 18 jump back by a few 1/10 mm. In these areas, additional adhesive is applied prior to assembly, so that after assembly, the side surfaces 41, 41 'of the end cap 18 are glued to the overlays 17 and 33. As a result, an additional seal and a higher corner strength are achieved.

In Fig. 12 to 14 is the corner area from the outside ( FIGS. 12 and 14 ) or from the side ( Fig. 13 ) after milling, wherein in particular the outer wall 31 of the narrower hollow chamber profile 1, which forms the outer visible surface 29, and the outer wall 32 of the wider hollow chamber profile 2, which forms the outer visible surface 30, can be seen. The outer walls 31 and 32 are opposite to the recessed milling (recessed profile portion 34) by a few millimeters above and thus form the outer Überblattung 33. The width of the end cap 18 corresponds to the width of the recessed profile portion 34 and thus the distance of the outer Überblattung 33 to the inner Overlapping 17.

In the FIGS. 15-17 It is shown that the outer Überblattung 33 and the inner Überblattung 17 cover the end cap 18 so that the end cap 18 in the view from the inside and - with the wing closed - can not be seen from the outside. In the FIGS. 15-17 are also the Dichtungsaufnahmenuten 36, 36 'in the area of the flashovers 10, 11 of the hollow chamber profiles 1, 2 and the Dichtungsaufnahmenut 35 of the end cap shown.
