Definitions

  • the invention relates to a composite frame for a window or a door with an outer attachment frame made of metal profiles connected to one another in the miter area and a base frame made of plastic profiles welded to one another in the miter area.
  • Plastic has established itself as a material for frame profiles for the manufacture of windows and doors due to the efficient processing and durability of the products in many markets.
  • Plastic profiles are always mitred and welded together in the miter area to form a frame.
  • the manufacture of window frames and casement frames from plastic profiles is usually carried out on complex production lines in which the individual work steps take place one after the other. In order to enable efficient production, none of the individual work steps may take significantly longer than other work steps, since otherwise the entire production line would have to be operated correspondingly more slowly.
  • facing shells or frames made from metal profiles and in particular from aluminum profiles is generally known for both wooden and plastic windows.
  • the cladding of plastic profiles with aluminum shells or frames is primarily done for aesthetic reasons, whereby the aluminum shells or frames can be anodized, painted or otherwise coated in different colors.
  • attachment shells which - without being connected to one another in the corner or miter area - are individually placed on the legs of a base frame and connected to it.
  • attachment frames prefabricated frames made of attachment profiles are referred to as attachment frames, which are connected to one another to form a fixed attachment frame in the corner or miter area before being connected to or placed on a base frame.
  • the corner connection can, for example, by means of special corner angles, as they are from the DE 100 08 037 B4 , of the DE 88 08 313 U1 or the EP 1 914 375 B1 are known, or, in the case of particularly high-quality designs, are made by welding in the miter area.
  • Plastic frames for a window or door with external, individual facing shells not interconnected before being placed on the base frame are, for example, from the EP 1 877 640 B1 or the DE 100 02 658 A1 known. Placing and connecting individual facing shells on a prefabricated plastic base frame, however, generally requires a relatively large amount of time, especially if the connection is made by gluing, screwing or with the aid of additional connecting means. Such constructions can therefore not be processed efficiently on conventional production lines.
  • the object of the present invention is therefore to provide a generic composite frame for a window or a door, in which different thermal expansions of the attachment frame made of metal and the base frame made of plastic as well as any tolerances in the manufacture of the respective frame can be compensated and in addition an efficient connection between the base frame and attachment frame is also made possible on correspondingly clocked production lines.
  • the invention achieves this object by a composite frame according to claim 1, preferably in connection with one or more of the features of the subclaims.
  • the composite frame according to the invention for a window or a door thus initially comprises an outer attachment frame made of metal profiles connected to one another in the corner area and a base frame made of plastic profiles welded together in the miter area.
  • the metal profiles are preferably mitred in the corner area, but can in principle also butt against one another. They are firmly connected to one another in the corner area, preferably by means of commercially available corner connectors, which are connected to the metal profiles via clamping screws, eccentric elements, beads, gluing or the like. According to a particularly preferred embodiment of the invention, the individual metal profiles are welded to one another in the corner area in order to form particularly high-quality attachment frames.
  • the metal profiles or the attachment frames formed from them are preferably refined on the visible outside by anodizing, painting or other coating.
  • the base frame according to the invention consists of plastic profiles welded to one another in the miter area, in particular hollow chamber profiles extruded from hard PVC (PVC-U).
  • the base frame and the attachment frame used according to the invention each have means which together form a latching function, so that the attachment frame and the base frame can be connected to one another during assembly by the latching function thus formed. It is essential to the invention that this locking function is designed in such a way that, before the filling is inserted, the attachment frame is arranged displaceably relative to the base frame in a plane parallel to the filling plane, the degree of displacement preferably being between a few 1/10 mm and a few mm.
  • the metal profiles forming the attachment frame have a relatively stiff, but at least to a certain extent elastic web with a locking lug, while the plastic profiles forming the base frame have an undercut or the like and so together with the webs and locking lugs of the attachment frame form the locking function according to the invention.
  • the attachment frame has exactly one circumferential latching nose which, with a corresponding circumferential undercut of the base frame, forms the only latching function between the attachment frame and the base frame. This ensures in a particularly advantageous manner that the necessary displaceability of the attachment frame with respect to the base frame is ensured before the filling or glazing is inserted and fixed.
  • the function of the undercut in the area of the corners can be impaired by the welding beads.
  • the so-called plastering of the miter areas of the base frame which is customary anyway, causes the weld beads in the area of the undercut usually removed anyway.
  • the circumferential elastic web with the locking lug of the attachment frame can be notched in the corner area in order to ensure that the attachment frame is locked to the base frame even under unfavorable circumstances.
  • the base frame has on its outside and at a distance from the undercut a - viewed in cross section - recess, which together with a - viewed in cross section - protruding into the recess support cam of the attachment frame a limitation of the displaceability of the attachment frame relative to the Basic frame causes. This facilitates the locking of the attachment frame and base frame and prevents the attachment frame from disengaging before the filling is inserted.
  • the composite frame according to the invention is designed as a casement frame.
  • the attachment frame also forms the external stop for the filling or glazing.
  • a conventional glass retaining strip is preferably used on the inside to hold the filling or glazing.
  • a corresponding glass retaining bead receiving groove on the inside of the rebate area of the plastic profiles from which the base frame is formed is used.
  • filling in particular triple glazing, is used as the filling.
  • another filling for example a highly insulating foam board, is used as the filling.
  • filling plane or “glazing plane” are used in the context of this application, this refers to the plane that is centered between the outer surface and the inner one Surface of the filling or glazing and runs parallel to these surfaces.
  • the composite frame according to the invention has a rebate area which is formed in a partial area by the attachment frame and in a partial area by the base frame.
  • the block bridges or glazing blocks used each rest at least 10% of their width both on the rebate area of the attachment frame and on the rebate area of the base frame.
  • a plurality of block bridges and / or glazing blocks are used to fix the filling or multiple glazing in the rebate area of the composite frame.
  • Block bridges are used in particular when the rebate area is not flat and / or does not run exactly horizontally. Block bridges can be dispensed with if the rebate area is largely flat and horizontal, i.e. perpendicular to the glazing plane. The block bridges thus serve to form a horizontal and flat surface for supporting the actual glazing blocks.
  • the glazing blocks are usually used at different heights in the circumferential gap between the circumferential face of the filling or glazing and the top of the block bridges or the rebate area in order to be able to compensate for tolerances of the frame in the rebate area and / or the external dimensions of the glazing or filling .
  • the filling or multiple glazing in the rebate area of the base frame can be glued in a manner known per se. Additionally or independently of the gluing in the rebate area of the base frame, the filling or multiple glazing can also be glued to the additional frame in the area of the attachment frame, for example by a double-sided adhesive tape that is used instead of or in addition to a glazing seal.
  • the attachment frame is centered relative to the base frame and at least largely fixed.
  • largely fixed it is meant that the extent to which the attachment frame can be moved relative to the base frame is restricted to such an extent that the latching function is ensured even when typical temperature fluctuations and forces and moments transmitted through the glazing are affected.
  • the rebate area runs both in the partial area formed by the attachment frame and in the partial area formed by the base frame, essentially flat and at the same height level running perpendicular to the glazing plane, so that if necessary a block bridge can be dispensed with.
  • the window 1 shown has, in addition to the composite frame 2 designed as a casement frame 14 according to the invention a conventional frame 28 equipped with a center seal 32.
  • the window frame 28 can also be provided with a facing shell or a facing frame made of metal, in particular made of aluminum.
  • the in Fig. 1 The sash frame 14 shown in cross-section consists essentially of the base frame 13, the attachment frame 3, the filling 23 designed as multiple glazing 25 and the glass retaining bead 27.
  • the base frame 13 is made of four plastic profiles 15 made of rigid PVC (PVC-U) welded together in the miter area. educated.
  • the plastic profiles 15 have a large central reinforcement chamber 30 for receiving a steel reinforcement 29 as well as a large number of additional chambers, which in particular bring about a higher thermal insulation of the base frame 13.
  • the folding area 19 of the base frame 13 is, as in particular in the Figures 3 and 4 shown, largely flat, in the illustrated embodiment including the inner area with the glass retaining strip receiving groove 22. This largely flat design of the rebate area 19 of the base frame 13 facilitates in particular an optional gluing of the filling 23 or multiple glazing 25 in the rebate area 19 (in Figs. not shown).
  • the plastic profiles 15 and the base frame 13 have - in cross section according to Fig. 1 , 3 and 4 viewed - on the outside in the upper area facing the rebate area 19 an undercut 16 which, if one looks at the base frame 13, forms a circumferential undercut edge which is used to hook the locking lug 6 of the attachment frame 3.
  • the plastic profiles 15 or the base frame 13 also have a recess 17 on the outside and spaced apart from the undercut 16, also viewed in cross section. This recess 17 serves, as will be explained in more detail below, as a contact surface for the support cam 8 of the attachment frame 3.
  • attachment frame 3 consists of four mitered and firmly connected to each other in the corner by corner connectors 31 metal profiles 4, which were made of aluminum in the illustrated embodiment.
  • corner connectors 31 used are commercially available and similar to the connectors in FIG EP 1 914 375 B1 built up.
  • the metal profiles 4 are in Fig. 2 shown separately in cross-section: They have a flat, in the installed state running parallel to the glazing plane 24 outer visible surface 5, an upper, slightly inclined in the direction of the multiple glazing 25, a receiving groove 11 for a glazing seal 12 and a receptacle 10 for receiving the Corner connector 31.
  • the attachment frame 3 is designed in such a way that the top of the web 7 runs at the same level as the rebate area 19 of the base frame 13 extending leg 9, which in the finished composite frame 2 completely covers the outside of the base frame 13 and ends in the support cam 8.
  • the attachment frame 3 is pressed onto the base frame 13 with a movement perpendicular to the glazing plane 24, the web 7 with its latching lug 6 being slightly - in cross section according to Figures 3 and 4 viewed - is bent upwards and springs back behind the undercut 16.
  • the support cam 8 rests against the recess 17 on the base frame 13 and at the same time transmits the data from the multiple glazing 25 via the glazing seal 12 Forces and moments acting on the attachment frame 3 on the base frame 13.
  • the locking function formed by the web 7 and locking lug 6 on the one hand and the undercut 16 on the other hand is designed with a certain amount of play, so that the attachment frame 3 relative to the base frame 13 is displaced up and down by a certain amount - viewed in cross section can, that is, the attachment frame 3 can be displaced to a certain extent in all directions in a plane which is parallel to the glazing plane 24.
  • This displaceability is limited by the extent to which the locking lug 6 meets the web 7 - in cross section according to FIG Fig. 4 viewed - protrudes downwards and through the distance between the support cams 8 of the attachment frame 3 of the edge 35 of the recess 17.
  • the composite frame 2 is glazed in a conventional manner by means of block bridges and / or glazing blocks 26.
  • the multiple glazing 25 is first inserted into the rebate area 18 of the composite frame 2 and blocked in the composite frame 2 by means of a corresponding number of block bridges and / or glazing blocks 26.
  • the circumferential end face 33 of the multiple glazing 25 is thus supported on the rebate area 18 via the block bridges and / or glazing blocks 26.
  • the block bridges or glazing blocks 26 are both on the - in cross section according to Fig. 4 viewed - top of the web 7 of the attachment frame 3 as well as in the rebate area 19 of the base frame 13.
  • the upper side of the web 7 thus forms the rebate area 20 of the attachment frame 3.
  • the rebate base seal 21 shown divides the rebate area 18 into an outside and an inside rebate area and thereby increases the thermal insulation of the window 1. In the area of the blockings, the rebate base seal 21 is pressed down into the rebate area which is set back here and therefore does not adversely affect the blocking.
