A positive and/or non-positive connection between the plug-in region and the frame connector is achieved by plugging-in the frame connector. The plug-in region is designed as an elongated strip, which is rectangular-inserted in a plug-in direction into the frame connector to a longitudinal direction of a lath. A clip lath is connected in a plane of a plug-in region at a proximal end of the plug-in region. The connecting part is made of plastic material.

Description

Technical area

The invention relates to a connecting part for connecting a frame connection part with a frame. Furthermore, the invention relates to a connecting part for connecting a first frame connection part with a second frame connection part.

State of the art

It is known to form the frame of a window, a door or similar Gebäudeöffnungsabschlusses with much smaller outer peripheral masses than the light mass of the building opening (also called Mauerlichtöffnung, window or Türaussparung), in which the frame is to be used. In the space between the frame and the inner edge sides of the building opening then plate-shaped frame connection parts are arranged. These frame attachment parts (frame widenings, window frame duplications) can be arranged on only one frame side (eg above), on several sides of the frame or also on all frame sides, so that they form a frame surround as a whole. Further, several frames, which are arranged both side by side as well as above each other (for example in a winter garden) can be connected via such frame connection parts. The frame connection parts have the function of fastening elements, which fasten the frame in the building opening, on the one hand, and the function of closing elements, which tightly close the building opening between the frame and the building opening edge, on the other hand.

Window and door frames are often made of hollow profiles made of plastic or metal (eg aluminum). For a good thermal insulation can be achieved, the hollow sections between their outer state in the installed state and their inner boundary in the installed state more partition walls parallel to the frame plane, so that in the hollow profile a plurality of mutually closed chambers are formed. Hollow profiles are known, for example, with a main chamber which is surrounded by two prechambers. In the case of plastic profiles, a metal frame reinforcement extending parallel to the frame plane is often arranged to improve the mechanical stability in the main chamber.

For the connection of the frame connection part with the hollow profile frame, various possibilities are known. Conventionally, a hole from the, the frame connector facing away from the frame inside through the frame (and thus possibly through the frame reinforcement) through to a core plate of the Frame connection part drilled. Thereafter, a screw is screwed into this hole until the screw head rests on the inside of the frame and a tensile connection between the frame and the frame connection part is created. Often the screw head is covered by a cap for aesthetic reasons, and to avoid injury from sharp edges. A connection can also be made via an H-profile, whereby a better lateral stability is achieved. For this purpose, the H-profile with the frame or the frame connector is screwed as described above.

For the screw to be held in the frame connector, the core plate must have a certain mechanical strength. To ensure this, it is made for example of a polyurethane foam (Puren) or a waterproof chipboard, while they are made of lighter polystyrene foam (EPS) surrounding insulating panels, which have no attachment function. Thus, the created by the hole through the frame through the cold bridge does not lead to a significant impairment of the thermal insulation capacity of the frame assembly, also between the frame and the core plate insulation is introduced, for. B. by means of a Kompribands surrounding the bore. The attachment of the frame connection part to the building opening is effected, for example, by a wall anchor, which is likewise secured in the core plate of the frame connection part by means of a second screw.

1. 1. Die im Rahmenanschlussteil zu Befestigungszwecken benötigte Kernplatte führt zu einem hohen Gewicht des Rahmenanschlussteils und beeinträchtigt die erzielten Isolationswerte.
2. 2. Die Montage der Rahmenverbreiterung ist aufwändig und teuer, besonders dann, wenn eine in der Hauptkammer befindliche Rahmenverstärkung aus Metall zu durchbohren ist.
3. 3. Bei vormontierten Rahmen mit Rahmenverbreiterungen ist der Transport durch das grosse Volumen aufwändig.
4. 4. Die Isolation des Rahmens wird trotz der zusätzlichen Isolation zwischen Rahmen und Anschlussteil vermindert.
5. 5. Der an der Rahmeninnenseite sichtbare Schraubenkopf (oder die entsprechende Abdeckung) beeinträchtigt die Ästhetik der Rahmenanordnung.
6. 6. Die Verschraubung ist gegenüber Zugkräften nicht solide. Die Schrauben können ausreissen, womit die Rahmenanordnung einknicken kann. Sie müssen daher häufig auf der Baustelle nachgezogen werden.

However, the known attachment of the frame connection part to the frame has a number of disadvantages:

1. 1. The core plate required for fastening purposes in the frame connection part leads to a high weight of the frame connection part and impairs the achieved isolation values.
2. 2. The mounting of the frame widening is complicated and expensive, especially if a located in the main chamber frame reinforcement made of metal is to be pierced.
3. 3. In the case of preassembled frames with frame extensions, transport is complicated due to the large volume.
4. 4. The insulation of the frame is reduced despite the additional insulation between frame and connector.
5. 5. The visible on the inside frame screw head (or the corresponding cover) affects the aesthetics of the frame assembly.
6. 6. The screw connection is not solid against tensile forces. The screws can tear out, causing the frame assembly to buckle. They must therefore often be tightened on site.

To address some of these disadvantages, other solutions have been proposed. The EP 1 191 180 A1 (Kurt Steineberg GmbH) shows a connecting device comprising projection-like connecting means, which are attached to the frame or the connecting part and which cooperate with grooves on the opposite part. The corresponding connecting means is screwed in the previously known manner in the connection part. But it can be avoided that the frame must be pierced. However, this device requires certain structural features (in particular suitable grooves) on the frame and / or on the connecting part. The connector must also absorb or transmit tensile forces for attachment of the frame in the building opening so that its construction can not be optimized for optimum thermal insulation out of consideration for mechanical requirements.

The EP 1 457 635 A1 (Kurt Steineberg GmbH) discloses a frame arrangement in which the frame connection part is held on the frame by means of an anchoring device which can be inserted into a groove, a threaded rod which can be attached thereto and a counterpart which can in turn be fastened thereto. The connecting device thus formed extends from the frame peripheral side to the building opening edge side and thus provides a high-tensile connection between the frame and the building opening edge. The connection part therefore no longer has to absorb or transmit tensile forces, so that its design can be aligned with optimum thermal insulation.

However, even with this frame assembly, the mounting of the connection part on the frame is quite complex, and here are certain design features on the frame provided. Furthermore, the transport of the assembled Frame arrangement consuming and cumbersome. In addition, because the frame assembly can warp due to the glands, these are not satisfactory from an aesthetic point of view.

In the CH 699 766 A2 (Kurt Steineberg GmbH), another frame assembly is disclosed in which a frame connector is attached via a clip attachment to a frame. For this purpose, a first clip device part is glued to the frame.

This frame arrangement also has the disadvantage that the bonding entails a waiting time until the adhesive has cured sufficiently. If the frame connection part is provided with the clip device part before delivery to the construction site, then the arrangement on the construction site can be adjusted only with difficulty if an error has occurred during the order or at the time of delivery.

The frame extensions are now ordered by the window manufacturers as custom-made pieces from the manufacturer and then mounted on the frame and delivered to the construction site. If the frame arrangement delivered at the construction site has errors, it takes a long time for the required replacement product to be delivered.

Presentation of the invention

The object of the invention is to provide a connection part belonging to the technical field mentioned above for connecting a frame connection part to a further frame connection part, respectively to a frame which is simply constructed, inexpensive to manufacture and can be used simply and variably.

The solution of the problem is defined by the features of claims 1 and 8. According to a first embodiment of the invention, the connecting part comprises a clip area, for pre-fixing the connecting part to the frame and a plug-in area for insertion into the frame connecting part, wherein by plugging a shape and / or non-positive connection between the plug-in area and the frame connection part is reached.

Due to the positive and / or non-positive connection, a particularly efficient assembly of a frame connection part is achieved on a frame, in particular because it no adhesives must be used. Furthermore, so that a reversible mounting can be achieved, in which at a faulty assembly of the frame separated from the frame connection part and also the connection part can be removed from the frame connection part. In particular, the assembly can be done in the simplest way on the site, bringing a space-saving and thus cost-effective transport of the frame assembly is achieved. The connecting part can be produced particularly inexpensively, for example in an injection molding process.

For receiving the plug-in area, a slot can be provided in the frame connection part, which slot can be arranged in particular in the isolation region of the frame connection part. This simplifies the exact positioning of the connection part in the frame connection part. The slot can be achieved by means of a milling process. In particular, the frame connection parts can already be prefabricated with such slots. In this case, for example, in the installed state of the frame and the frame connection parts vertical and horizontal slots may be arranged with respect to a main surface in different planes, so that in T-shaped connection regions, the connecting parts do not abut each other. For this purpose, the connecting parts can be present in two different variants, which differ correspondingly at the spacing of the plug-in region from the clip region.

Preferably, the frame connection part is designed essentially as a sandwich element. The sandwich element preferably comprises at least two layers, wherein the layers may have different properties, for. For example, they can be force-absorbing, heat-insulating or acoustically insulating. The sandwich construction thus has the advantage that several different desired properties can be formed in the same element. Furthermore, sandwich panels can be manufactured in lightweight construction, which can be advantageous in terms of transportation and handling, in particular on the construction site. The usable Materials are selectable from a large variety. Not suitable as insulating materials depending on the field of application are organic foams (for example Puren, polyethylene, polystyrene, polystyrene extruder foam (XPS), Neopor, polyurethane or similar), mineral foams (for example cellular concrete, pumice, perlite, expanded clay, expanded mica, calcium silicate plates, Foam glass or the like), with traces being preferred for its strength and good insulating properties. The insulating material is preferably held between two plastic plates. On the other hand, the frame connection part can also be formed in one piece.

Preferably, the frame connection part comprises at least two side walls and a core. Typically, the two side walls are formed identically and lie in the frame connection part parallel to one another, wherein a gap formed is substantially filled by the core. Two different side walls are also conceivable, for. For example, in the case of an external window, a first side wall exposed to weathering could be formed, for example, from weather-resistant plastic, and a second side wall made of wood, for example adjoining a living area, or suitable for an interior of the room. If the building wall is made of wood, exposed to the weather side wall of the same wood is also conceivable. Preferably, however, both side walls made of the same building material. In particular, made of plastic (for example, XPS) trained side walls for cost reasons and because of the low weight to be preferred. Depending on the field of application, aluminum is also a preferred building material for the production of the side walls due to its good weather resistance. Also, any other materials that can be designed as thin plates are conceivable.

Alternatively, the frame connection part may also be formed without a core, in particular if no sound-insulating property is required. This is a cheaper, good heat insulation exhibiting and up to 75% lighter frame connection part is achieved. In this case, for example, transverse struts between the two walls may be provided for their stabilization. On the other hand, instead of the transverse struts, a jacket frame may be provided for attaching the side walls. The jacket frame can be substantially formed as a cuboid, wherein the bottom and the top surface are represented by the side walls of the frame connection part. The jacket frame does not necessarily have a flat filled coat, but can z. B. also be designed as a frame profile, wherein the edges defining the cuboid are formed, for example, as angle strips, which in turn define bearing surfaces for the side walls as well as for the connecting part. Finally, it is also conceivable that the frame connection part is formed integrally and solidly from a single material, which is to be chosen with advantage such that it is at the same time easy, allows good insulation and is weather-resistant. Furthermore, documents can be glued on the inside of the frame connection part, for example, so that increased stability can be achieved for screwing a device to the frame connection part. This is particularly advantageous if, for example, bolted to the frame connection part a connecting rod or a radiator is mounted.

Preferably, the core of the frame connection part consists of insulating material. In particular, in a mounted in an outdoor frame connector part, it is advantageous if the core of the same is insulating, since it can be dispensed with further insulation and thus costs and labor can be saved. The core preferably comprises traces, respectively styrofoam, due to the good insulation properties and the relatively high compressive strength. By a high compressive strength of the core, the same can take over to a certain extent bearing properties of the frame connection part. For example, the side walls may be connected over the core by means of gluing, screwing or the like.

The frame is preferably formed as a window frame or door frame. The frame can be made of plastic as well as of a metal such as aluminum or wood. The frame can be formed both of solid material as well as a hollow profile. Preferably, a wooden frame made of solid material and a plastic or metal frame is designed as a hollow profile. Plastics are also understood as composites. Wooden frames may be made of solid wood or wooden products such as chipboard, chipboard or the like.

Preferably, the plug-in portion is formed as an elongated strip which is perpendicular to a longitudinal direction of the bar in the insertion direction in the frame connector part inserted. Thus, the connection part can extend over the entire length of the frame connection part, whereby no deformations during assembly, which are known, for example, in screw, occur.

In variants of the plug-in area, respectively, the connecting part may also be provided only in sections. The plug-in area can therefore basically also be designed as a screw, possibly with a suitable plug, pin or the like. The attachment can also be done by gluing.

Preferably, in a plane of the plug-in area at the proximal end of the plug-in area a clip strip adjoins, wherein the clip strip comprises a locking strip standing at right angles to the plane and wherein the clip strip and the locking strip form the clip device. Particularly preferably, the clip strip is resilient with respect to the mating region. This design of the clip area is characterized by the particularly simple construction and the resulting low production costs. This clip device can now be clipped into an opening, in particular in a longitudinal slot of a frame, wherein the locking strip engages behind a longitudinal slot edge in the locked state. The locking strips may have a cross-sectional profile which is substantially rectangular. Further, the locking bar may also be formed ramp-shaped in a proximal region, so that the assembly is facilitated.

The locking strips can also be undercut with respect to the clip strip in the distal direction and be formed ramp-shaped in the proximal direction. Thus, the clip device may be guided during insertion into a slot on the ramp and then be compressed by the slot of the distal portion of the locking bar in the region of the undercut. After complete insertion of the clip device into the slot, the distal region of the locking strip engages behind the slot and simultaneously acts as a kind of barb, so that the clip device is held inseparably in the slot of a frame. The person skilled in the art also knows other suitable clip devices.

In variants, a clip area can also be formed directly on the plug-in area, so that it is possible to dispense with the clip strip. Instead of a continuous locking strip, the locking strip may also be provided in sections or individual locking lugs.

Preferably, the clip strip comprises two locking strips. The locking strips can be spaced with respect to the proximal direction and arranged on the same side of the clip strip. Thus, the clip device can be locked in an opening such that the proximal rear locking strip engages behind a bar of a frame and counteracts the proximal front locking bar on the opposite side of the bar. Thus, the bar of the frame can be optimally fixed.

However, the two locking strips can also be arranged on opposite sides of the clip strip, so that the locking strips can engage behind two strips of a frame. In this case, preferably the locking strips or the strips of the frame are at least partially elastic. Finally, the clip strip can also comprise two latching strips on both sides, with which the clip device can be fixed in a frame with respect to the distal as well as the proximal direction.

In variants, the second clip strip can also be dispensed with. In particular, the function of the second clip strip can also be taken over by a proximal end of the plug-in region (lowermost "branches of the Christmas tree").

Preferably, the connecting part comprises two mutually parallel and spaced Clipleisten, both Clipleisten comprise a locking bar on a side facing away from the other clip strip side. In other words, the clip device comprises a clip strip with opposing locking strips, wherein the clip strip is slotted in strip longitudinal direction. By this design, the clip device can be made more stable, since the resilient property is now formed instead of the locking bar on the larger clip strip.

In variants, the slotted clip strip can also be dispensed with.

Preferably, a mounting strip extends at right angles to a proximal end of the plug-in region, wherein the clip region extends on the side opposite the plug-in region a clip device comprises. The formation of a mounting strip a support area is created for both the frame connector and the frame. This simplifies a precise connection of the frame connection part to the frame.

In variants, the mounting bar can also be dispensed with. In this case, the clip area and the plug-in area would lie in the same plane, respectively be aligned with each other.

Preferably, a proximal end of the mating portion opposite end of the mounting bar is T-shaped, so that in the assembled state, a gap between the frame connection part and frame is covered outside. Thus, a particularly aesthetic transition between the frame connection part and the frame is created, in particular if the color of the frame and the frame connection part do not match exactly. For this purpose, a cover plate is preferably mounted on the main surfaces of the frame and the frame connection part, which is provided in the transition region between the frame and the frame connection part with a shoulder, in which the T-shaped area comes to rest. It may also include the main surfaces of the frame and the frame connector itself such a paragraph. Finally, the heel can also be dispensed with, in which case the T-shaped region would protrude from the main surfaces of the frame and the frame attachment part. Next so that also the connecting part on the frame, respectively held on the frame connector in addition in position. In particular, when prefixing the connecting part to the frame can be created with the formation of the T-shaped portion of the mounting rail a solid connection, since thus the connecting part can also be fixed transversely to the frame.

In variants, instead of the T-shaped region, an L-shaped region can also be provided, with which only a shoulder corresponding to the L-shaped region can be provided either on the cover plate of the frame or on the cover plate of the frame connection part. On the other hand, can be completely dispensed with the T-shaped portion of the mounting rail.

Preferably, the plug-in area comprises barbs. This can be created in a particularly simple manner a positive and non-positive connection with a frame connection part. Particularly preferably, the barbs of the plug-in area are formed as undercut ramps, which run in the longitudinal direction of the bar and taper in the distal direction. Thus, the plug-in area can be pushed with relatively little force in the frame connection part, while the connector is sufficiently tensile strength. For this purpose, preferably a frame connection part is used with an insulating material which has at least slightly elastic properties.

In variants, it may also be sufficient to provide the plug-in area with other structures, such as grooves or jaws protruding perpendicularly from the plug-in area. A suitable design of the plug-in area also depends on the insulating material of the frame connection part. The person skilled in the art is also familiar with further suitable structures.

Preferably, the connecting part is made of plastic. For a simple and inexpensive to produce connecting part is created. Particularly preferably, the connecting part consists of polystyrene extruder foam (XPS). Preferably, the connecting part is also formed in one piece.

In variants, the connecting part may also be formed from metal, such as aluminum or the like.

According to a second embodiment of the invention, the connecting part is designed for connecting a first frame connection part to a second frame connection part or frame, wherein the connection part comprises a first insertion region for insertion into the first frame attachment part and a second insertion region for insertion into the second frame attachment part or frame, with which first frame connection part and the second frame connection part or frame via the connection part positively and / or non-positively connectable. In this case, the connecting part may be formed substantially in accordance with the first embodiment described above, wherein only a second plug-in area is provided instead of a clip area. This embodiment is particularly advantageous in the Connection of two frame connection parts or else for connecting frames such as window frames or door frames made of solid material with a frame connection part. In order to accommodate the second mating region of the connecting part, the frame is preferably slotted, respectively milled a groove which has at least the depth of the mating region. The width of the slot is dimensioned such that when plugged into the groove plug-in area a positive and / or non-positive connection can be achieved. Particularly preferably, this connecting part is used for window or door frames made of wood, as can be milled or sawed or otherwise incorporated in wooden frame particularly simple slot for receiving the mating portion of the connecting part. Of course, a wooden frame can already be made such that there is such a slot on the circumference, or at least on one side.

By means of this second embodiment, the frame connection parts or frame connection part and frame can be combined in situ in a simple manner, in particular on the construction site.

Typically, the frame fittings are manufactured in unitary sizes so that the transport of the frame fittings can be simplified. On the construction site, however, one is often confronted with the situation that frame connection parts are required, which are larger than the standard size. Next typically also frame arrangements can be created, which surround a window frame, whereby the frame connection parts under each other, but also frame connection parts with window frames must be connected. For both cases, this second embodiment provides a particularly simple and inexpensive connection technique, which can be used in particular without the use of tools. In addition, the same connection part can be used both for connecting two frame connection parts as well as for connecting a frame connection part to a frame.

In order to further simplify the application, the frame connection parts in the area of the insulation material, that is to say parallel to the outer skin, can have cutouts for guiding the plug-in area. For a precise connector is achieved, whereby the exact alignment of the outer surfaces of the frame connection parts can be ensured. The slot can be achieved by means of a milling process or be prefabricated accordingly. In this case, for example, in the installed state of the frame and the frame connection parts vertical and horizontal slots may be arranged with respect to a main surface in different planes, so that in T-shaped connection regions, the connecting parts do not abut each other. For this purpose, the connecting parts can be present in two different variants, which differ in the distance of the mating region to the clip region according to the position of the incisions in the frame connection part. Similarly, slots can be placed in frames, such as window or door frames, especially in wooden frames.

Preferably, the first plug-in area and the second plug-in area are strip-shaped and, in particular, lying in the same plane. For a structurally particularly simple constructed connecting part is created, which is also easy and inexpensive to produce. Preferably, the plug-in areas are formed as elongated strips which can be inserted at right angles to a longitudinal direction of the strip in the insertion direction into the frame connection part or frame. Thus, the connecting part can extend over the entire length of the Rahmenanschlussteils or frame, which occurs no deformation during assembly. The fact that the two plug-in areas lie in the same plane further simplifies the connection of two frame connection parts or of a frame connection part with a frame, since in this way the forces occurring during assembly lie in the same plane. Thus, damage to the connecting part during assembly can be largely prevented.

In variants, the plug-in areas can also be provided only in sections. The two plug-in areas do not necessarily have to lie in the same plane; in principle, they can also be offset from one another, arranged essentially in a Z-shape, but the two plug-in areas preferably run parallel.

The first plug-in area and the second plug-in area preferably include barbs. This can be created in a particularly simple manner a positive and non-positive connection with the frame connection parts. Particularly preferably, the barbs are formed as undercut ramps, which extend in the longitudinal direction of the bar and taper in the distal direction. This allows the plug-in area with relatively little force be pushed into the frame connection part or frame, while the connector is sufficiently tensile strength. For this purpose, preferably a frame connection part is used with an insulating material which has at least slightly elastic properties. Alternatively (in particular in the case of non-elastic frames) or in addition, the plug-in region can also have elastic properties.

In variants, it may also be sufficient to provide the plug-in area with other structures, such as grooves or jaws protruding perpendicularly from the plug-in area. The person skilled in the art is also familiar with further suitable structures.

Preferably, the first plug-in area and the second plug-in area are arranged on opposite sides of a mounting strip, wherein a distal end of the mounting bar is in particular T-shaped, so that in the assembled state, a gap between the frame connection parts or the frame connection part and the frame is covered outside. This creates a particularly aesthetic transition between the frame connection parts or the frame connection part and the frame, in particular if the color of the frame and the frame connection parts to be connected do not coincide exactly. The mounting strip is in each case perpendicular to the plug-in areas, whereby in the assembled state, the mounting strip comes to rest in the connection plane of the two frame connection parts or the frame connection part and the frame. The mounting strip thus forms during assembly also a stop, so that it is ensured that the plug-in areas are inserted in each case in a defined depth in the frame connection parts. Without the mounting rail, there would be a risk that during installation, the two plug-in areas are inserted unevenly into the frame connection parts or frames, whereby the stability of the connection of the frame connection parts or the frame connection part and the frame can be impaired.

In variants, the T-shape of the mounting strip can also be dispensed with. Instead of the mounting strip can also be provided in sections, a right-angled oriented to the plug-in areas stop. This can be formed for example as a tongue or the like. Furthermore, only a material thickening can be provided between the plug-in areas. Finally, on the mounting bar too be completely dispensed with, especially if in the frame connection parts, for example, by an incision of defined depth, a sufficiently solid stop for the plug-in areas is formed.

In a further embodiment, the plug-in area can also be firmly connected to the frame, in particular a window frame. Preferably, the plug-in area is formed integrally with the frame in this embodiment. For a particularly simple and inexpensive frame system is created, which works with two parts, namely with the frame and the frame widening. In variants, however, the plug-in area can also be manufactured separately and subsequently connected to the frame, for example by gluing or welding. The frame can be formed in this case, largely without inner braces, since according to the invention, the stability is created by the connection with a frame widening. This achieves a frame system with optimized thermal insulation. In variants but the plug-in area can also be formed on a frame with braces. Commercial frames include an area with inserts for receiving mounting screws for bolting the frames to the frame widening. In this area can be dispensed with by the inventive compound, which in principle the frame, in particular windows and door frames can be easily constructed. The connecting part can be used for most known PVC window profile systems, for example at profile thicknesses between 50 and 100 mm.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Ways to carry out the invention

The FIG. 1 shows a schematic oblique view of a connecting part 100 with a clip area 120 and a plug-in area 110. The connecting part 100 comprises a mounting strip 101, which is formed as an elongated strip. At the one longitudinal side 102 of the mounting strip 101 is connected at right angles to the first main surface 101a, a plug-in portion 110, which is also formed as an elongated strip which extends over the entire length of the mounting strip 101 and in the longitudinal direction on both sides ramps 111. The ramps 111 are oriented transversely to the longitudinal direction and at right angles to the mounting strip 101 such that the direction of inclination in the proximal direction, that is to say from the mounting strip 101, is inclined at right angles in the direction of the plug-in region 110. The individual ramps 111, except for the one which is arranged distally, in each case undercut the following ramp 111. A single ramp 111 has the shape of an obtuse-angled triangle in cross-section. In the cross section of the plug-in area 110 thus results in a shape that is reminiscent of a lance tip with barbs or a Christmas tree. The plug-in area 110 is designed in such a way that it has an anti-hacking effect in the inserted state, and thus can withstand a tensile load.

On the plug-in area 110 opposite side of the mounting strip 101, along the second longitudinal side 103, the mounting strip 101 has a T-shape 104. Thus, in the assembled state, an aesthetic transition between the frame connection part 200 and the frame 300 is made possible (see below). FIG. 2b ). Next, this area serves to support the clip connection, as well as positioning aid during assembly.

On the second main surface 101b of the mounting bar 101, an L-shaped bar 120 is arranged approximately in the middle, which forms the clip area 120. The first edge 121 of the bar 120 is connected at right angles in the longitudinal direction of the mounting strip 101 and extends over the entire length of the mounting strip 101. At the distal longitudinal edge of the edge 121, which is opposite to the mounting strip 101, the second edge 122 is arranged at right angles to the edge 121. This is oriented in the direction of the T-shaped portion of the mounting strip 101. The second flank 122 has a chamfer in the distal edge region which runs in the distal direction and toward the mounting strip 101.

The connecting part 100 is preferably formed in one piece and consists of plastic, for example, polystyrene extruder foam (XPS).

The FIG. 2a shows a schematic view of a cross section of a frame assembly perpendicular to a longitudinal direction of the frame assembly, comprising two connecting parts 100 each having a clip portion 120 and a plug-in portion 110 according to FIG. 1 , and a frame connector 200 and a frame 300 prior to assembly.

The Indian FIG. 2 shown frame 300 is in this form z. B. by the company Veka AG, Sendenhorst, Germany. In the following, only the contact region of the frame 300 to the frame connection part 200 will be discussed, since the exact design of the inner frame life is not of interest here. For the present invention, any type of frame may be used which has grooves and / or profiles in a region of a connection to a frame connection part, it being possible for the clip region 120 of the connection part 100 to be adapted as appropriate.

The present frame 300 comprises two parallel side walls 301 a, 301 b and has a clip device 303, which is incorporated in the frame 300. The clip device 303 has a base surface 304, which is in the assembled state parallel to the mounting strip 101 of the connecting part 100 (see FIG. 2b ). At right angles to the base surface 304 are marginal with respect to a width of the clip device 303 two L-shaped profiles 305a, 305d, the short legs are aligned inwardly arranged. Furthermore, two T-shaped profiles 305b, 305c are connected to the base surface 304 between the two L-shaped profiles 305a, 305d. All profiles 305a, 305b, 305c, 305d extend parallel in a longitudinal direction of the frame 300. The clip region 120 of the connection part is designed such that it matches the L-shaped profile 305a, respectively 305d of the frame 300 can make a positive and non-positive connection. For this purpose, the connecting part 100 is pressed at right angles to the base surface 304 of the frame, so that the clip region 120 is pivoted by pressurization over the chamfer of the second flank 122 to the L-shaped profile 305a, respectively 305d, wherein subsequently the second flank 122 of the clip region the L- shaped profile. shaped profile 305a engages behind and locked it.

The T-shaped profile 305b acts in the present embodiment as a support for the one connecting part 100, but with an additional corresponding, connected to the first clip device part 100 profile (not shown) quite another clip connection could be created. Depending on the configuration of the connecting part 100, the T-shaped profile 305c may also support the connecting part 100.

The frame 300 further comprises on the outside on the side walls 301 a, 301 b each have a cover plate 302 a, 302 b, which allow an aligned transition with the T-shaped portion 104 of the connecting part 100. For this purpose, these cover plates 302a, 302b each set back slightly with respect to the side walls 301a, 301b.

The frame connection part 200 comprises two parallel side walls 201 a, 201 b which enclose a cuboid core 204. Furthermore, the frame connection part 200 also comprises two cover plates 202a, 202b, which substantially correspond to the cover plates 302a, 302b of the frame and, when mounted, allow a smooth transition between the frame 300 and the frame attachment part 200. Parallel to the side walls 201a, 201b, the frame connection part has two notches 203a, 203b for receiving the plug-in regions 110 of the connection parts 100. These cuts 203a, 203b can be incorporated into the frame connection part 200 in a simple manner known to the person skilled in the art, in particular, for example, with a bench milling machine on the construction site. On the other hand, the incisions 203a, 203b can already be incorporated when the frame connection parts 200 are delivered.

The FIG. 2b shows a schematic view according to FIG. 2a after assembly. For assembly, the two connecting parts 100, the frame 300 and the

Frame connector 200 positioned and pushed together. The second flank 122 of the two connecting parts 100 engage behind the L-shaped profile 305a, respectively 305d, so that a tension-proof, positive and non-positive connection between the connecting parts 100 and the frame 300 is created. The plug-in areas 110 of the connection parts 100 are respectively inserted into the notches 203 a, 203 b of the frame connection part 200. The barbs (ramps 111) of the plug-in regions 110 thus also result in a tensile, positive and non-positive connection between the connection parts 100 and the frame connection part 200. Thus, the frame 300 and the frame connection part 200 are easily tension-resistant via the two connection parts 100 the connecting parts 100 connected.

The FIG. 3 shows a schematic oblique view of a second embodiment of a connecting part 400, which in contrast to the connecting part 100 comprises two plug-in areas 410, 420.

The connecting part 400 comprises a mounting strip 401, which is designed as an elongated strip. At the one longitudinal side 402 of the mounting strip 401 is connected at right angles to the first main surface 401a, a plug-in portion 410, which is also formed as an elongated strip which extends over the entire length of the mounting strip 401 and in the longitudinal direction on both sides ramps 411. On the side of the mounting strip 401 opposite the plug-in region 410, a second plug-in region 420, which corresponds to the plug-in region 410, closes at right angles on the second main surface 401b. The two plug-in areas 410, 420 lie in one plane and are arranged in mirror image with respect to a plane of the mounting strip 401. The ramps 411 and 421 of the two plug-in areas 410, 420 are formed in accordance with the plug-in area 110 of the connection part 100.

On the plug-in areas 410, 420 opposite side of the mounting strip 401, along the second longitudinal side 403, the mounting strip 401 also has a T-shape 404. Thus, in the assembled state, an aesthetic transition between the frame connection parts 200 is made possible (see below). FIG. 4b ). Next, this area also serves to support the clip connection, as well as positioning aid during assembly.

The connecting part 400 is also preferably formed in one piece and is made of plastic, for example, polystyrene extruder foam (XPS).

The FIG. 4a shows a schematic view of a cross section of a frame assembly perpendicular to a longitudinal direction of the frame assembly, comprising two connecting parts 400, each with two plug-in areas 410, 420 according to FIG. 3 , as well as two frame connection parts 200 to be connected, which correspond to those of FIGS. 2a and 2b correspond (see above).

The FIG. 4b shows a schematic view according to FIG. 4a after assembly. For assembly, the two connecting parts 400 are inserted via the plug-in regions 410 into the notches 203a, 203b of the one frame connection part 200. Subsequently, the two frame connection parts 200 are pressed together, so that the plug-in areas 420 of the connection parts 400 are inserted in the notches 203a, 203b of the other frame connection part 200. The barbs (ramps 411, 421) of the plug-in areas 410, 420 thus result in a tensile, positive and non-positive connection between the connecting parts 400 and the frame connection parts 200. The frame connection parts 200 can thus be easily connected via the two connection parts 400, in particular without Use of tools, tensile strength over the connecting parts 400 are connected.

In the following FIGS. 5 to 7 Variants of the connecting part are each shown in a cross section. However, in the present embodiments, the connecting parts each have a longitudinal extent which corresponds to a length of a frame side to be connected. Of course, the use of shorter connecting parts is also conceivable, in which case several, either in the assembled state contacting or spaced-apart connecting parts would be used.

The FIG. 5 shows a schematic view of a cross section of a frame assembly perpendicular to a longitudinal direction of the frame assembly comprising connecting parts 100.1 according to a second embodiment. The frame 300 and the frame connector 200 are the same as those of FIGS FIGS. 2a, 2b described. The connecting part 100.1 comprises a plug-in area 110, which corresponds to the plug-in area 110 of the connecting part 100, and a clip area 120.1 extending proximally to the plug-in area 110. In the present exemplary embodiment, the clip region 120.1, in particular the clip strip, is aligned parallel to a plug region plane, but not exactly lying in the same plane, but slightly offset from a plane central to the plug region 110. In the present case, the locking strip has a triangular cross-section and faces away from the central plane. Although in the present case a regular triangle is selected as the cross-sectional area, a rectangular shape of the cross-sectional area can also be provided, but the clip connection can be loosened after latching less well or no longer destructive. The locking strip of a connecting part 100.1 engages behind in the present FIG. 5 in the assembled state, the L-shaped profile 305a - the other engages behind the L-shaped profile 305d.

In the following FIGS. 5 and 7 For example, the frame connectors 200 are not shown for clarity. For the following embodiments 100.2 and 100.3 of the connecting parts, in each case the frame 300 is slotted along the base surface 304, so that the clip regions 120.2 and 120.3 respectively can engage in these slots. Thus, the respective clip area 120.2 or 120.3 longer is formed.

The FIG. 6 shows a schematic view of a cross section of a frame 300 at right angles to a longitudinal direction of the frame, comprising connecting parts 100.2 according to a third embodiment.

The FIG. 7 shows a schematic view according to FIG. 6 with connecting parts according to a fourth embodiment,

In both embodiments, it is common that they each comprise two locking strips on both opposite sides of the clip region 120.2 and 120.3, respectively. In the mounted state, an edge of the slotted base 304 can be received between two locking strips on one side of the clip region 120.2 or 120.3 and can thus create a stable connection between the connecting part 100.2 or 100.3 and the frame 300. As a result of that two locking strips are provided, and the proximal front connecting part can engage behind the slotted base 304. This variant is in the FIG. 5 shown at L-shaped profile 305d. In particular, it can be seen that the connecting part 100.2 is designed such that in this state, the proximally lowest ramp of the plug-in portion 110 engages behind the L-shaped profile 305d, whereby the stability of the clip connection can be increased (but this is of course not necessarily provided). This provides two positioning options and allows variable deployment.

The two connecting parts 100.2 and 100.3 essentially have two differences. The connecting part 100.2 slotted in the longitudinal direction of the clip area 120.2. This achieves an improved spring effect with increased stability of the clip areas 120.2. Since this allows the locking strips to be made more stable, they are formed ramp-shaped. Thus, the insertion of the clip area can be facilitated in the slot.

The connecting part 100.3 is not slotted here. Thus, when inserting the clip portion 12.3 in the slot of the base 304 of the frame 300 either the locking bars or the base 304 is deformed so that the clip connection can engage.

A fourth embodiment of the connecting part shows the FIG. 8 , This figure shows a schematic view of a cross-section of a frame assembly perpendicular to a longitudinal direction of the frame assembly, wherein the mating portion is directly connected to the frame. In this case, the clip area is dispensed with, so that only one plug-in area 110 is used. In contrast to the preceding embodiments, the frame 300.1 is narrower, in the illustration the clip connection region of the frame 300.1 is "cut away", for which the plug region 110 is firmly connected directly to the frame 300.1. Preferably, the plug-in portion 110 is formed integrally with the frame 300.1, but it can also be fixed to the frame 300.1 by means known to those skilled in the art, for example by gluing. The frame 300.1 can certainly be unstable to a certain extent, because the final stability of the frame 300.1 is achieved only by inserting the plug-in regions 110 into the frame connection parts 200. Opposite the frame 300 according to the above FIGS. 2a, 2b is thus achieved a better insulation effect, since the frame 300 of the embodiments according to the FIGS. 2a, 2b typically represents a weak point of isolation. The frame 300.1 can thus be constructed much simpler, since largely can be dispensed struts in the frame 300.1. In addition, no separate connecting parts have to be produced, cut to length and mounted, since these are already covered by the frame 300.1.

Finally, instead of the clip area, a further plug-in area can also be provided, whereby a connection to the frame 300 can likewise be provided. Preferably, in turn, the frame 300 is slotted for this mounting method.

It is clear to the person skilled in the art that the plug-in region 110 can also be configured differently. For example, the ramps 111 do not necessarily have to be undercut, but can also have the shape of right-angled triangles in cross-section. On the T-shaped portion of the mounting strip 101 can also be dispensed with. Also, the cover plates 202a, 202b, 302a, 302b need not necessarily be provided. It is also possible to dispense with the cuts 203a, 203b if the plug-in region 110 of the connecting part 100 can also be driven directly into the core 204.

In general, the scope of the invention is not limited to end elements for building openings such as doors or windows. Frame arrangements according to the invention can be used wherever a frame is to be provided with a frame connection element (a frame widening), that is to say, for example. As in conservatories or pavilions in which entire walls or roof elements are constructed of several interconnected frame.

The FIG. 9 shows a schematic view of a cross section of a frame assembly perpendicular to a longitudinal direction of the frame assembly comprising two strip or plate-shaped connecting parts 400.1, each with two mating areas 410, 420 substantially according to FIG. 3 , and a frame connector 200 and a frame 300.2. The entire frame arrangement corresponds largely to that of FIG. 4b , with the difference that instead of two frame connection parts 200, a frame connection part 200 with a frame 300.2 with two connection parts 400.1 connected is. In contrast to the above exemplary embodiments, the frame 300. 2 consists essentially of wood, ie it is designed as a conventional wooden frame, or wooden door frame or wooden window frame, and comprises two slots 303.a, 303.b for receiving a plug-in region of a respective connecting part 400.1. The connecting parts 400.1 are not T-shaped in the present case. They comprise two opposite plug-in areas 410, 420, which lie in one plane. In other words, the present connection parts 400.1 are a strip-shaped connection part 400.1, wherein the two opposite longitudinal edges are each formed as plug-in regions 410, 420. The plug-in region 410, 420 can each extend to the middle between the two longitudinal edges. However, it is clear to the person skilled in the art that a connection part 400 according to FIG FIG. 4b , That is, in cross-section to the longitudinal direction T-shaped connecting part 400 may be provided.

In summary, it should be noted that by the inventive method in a simple and inexpensive way, a frame broadening can be achieved, with essentially no tools needed for assembly and the broadening can be carried out in particular on the site, so that transport volume and thus transport costs can be reduced.
