Abstract

The present invention relates to a profile connector (5.1, 5.2, 6.1, 6.2) comprising at least one first connection leg (7) that can be inserted into a profile strip (3, 4) and a second connection leg (8) that can be inserted into a profile strip (3, 4).

Description

The present invention relates to a profile connector, comprising at least a first connecting leg that can be inserted into a profile bar and a second connecting leg that can be inserted into a profile bar. The invention also relates to a frame of a protective device, such as an insect screen or light well cover, for use with a building opening, such as a window or door, comprising such a profile connector and at least two vertical frame struts, each of which has at least one outer profile strip and at least one telescopic with an insertion depth into the outer profile strip have inserted inner profile bar, as well as at least two horizontal frame struts, each having at least one outer profile bar and at least one telescopically inserted inner profile bar with an insertion depth, the first connecting leg being inserted at least in sections into a profile bar of a vertical frame strut and the second connecting leg at least in sections a profile bar of a horizontal frame strut is inserted. Such a frame can be easily adapted to the size of a building opening due to the telescopic nature of the inner profile strips and outer profile strips of the frame struts.

A frame with the aforementioned features is, for example, from EP 3 138 990 B1 known. The components of such a frame are generally made available to the end user as a kit, so that the end user must first assemble the components before an insect protection net can be attached to the frame. For this purpose, the end user must in particular insert the profile connectors into the respective profile strips of the frame struts, if necessary with the aid of a tool. To reduce the assembly effort in this regard, for example, is off DE 10 2015 116 588 A1 known to pre-assemble profile strip pairs of two frame struts over the corner connector. In this case, however, a relatively large packaging is required, since the pairs of profile strips arranged at right angles to one another and connected to one another via a corner connector span a large area. With this solution, the end user also has to insert the pre-assembled profile strips into profile strips of other pre-assembled profile strip pairs.

The object of the present invention is therefore to eliminate the disadvantages described with reference to the prior art and, in particular, to provide a profile connector with which the frame can be assembled more easily and with less effort.

The task is solved by a profile connector with the features of the independent claim. Advantageous further developments of the profile connector are specified in the dependent claims and in the description, wherein individual features of the advantageous further developments can be combined with one another in a technically meaningful manner.

The object is achieved in particular by a profile connector with the features mentioned at the beginning, in which a swivel joint having at least one axis of rotation between the first connecting leg and the second connecting leg is formed so that the first connecting leg and the second connecting leg can be transferred from an initial position by a relative pivoting movement about the at least one axis of rotation of the swivel joint into an assembly position in which the first connecting leg and the second connecting leg are at a right angle to one another in one plane are arranged, and the first connecting leg has a first receiving channel and the second connecting leg has a second receiving channel, the first receiving channel and the second receiving channel being arranged in alignment with one another in the mounting position, and in which a separate fixing element is provided, the fixing element in the mounting position can be introduced into the first receiving channel and into the second receiving channel, so that the first connecting leg and the second connecting leg are secured against relative movement.

The basic idea of the invention therefore provides that the at least two connecting legs of the profile connector are connected to one another in a hinge-like manner indirectly or directly via the swivel joint, so that the connecting legs can be transferred from a compact starting position into an assembly position in which the two connecting legs are in one plane are arranged at a right angle to one another, at least the two connecting legs being secured in the mounting position by inserting the fixing element into the two receiving channels, so that pivoting back of the connecting legs out of the mounting position is prevented.

The connecting legs of the profile connectors each have, in particular, an insertion section which can be inserted into the profile strip and which is fixed or fixable in the profile strip in a non-positive and / or positive manner. For this purpose, the outer circumferential design of the insert section can match the inner cross-sectional profile of a profile strip, so that the insert section can be inserted into the corresponding profile strip. In addition, each connecting leg can in particular have a corner section which projects beyond the profiled strip and is therefore arranged outside the profiled strip, in particular in one piece with the insertion section, on or in which the at least one axis of rotation of the swivel joint is formed. The corner section can have a stop surface against which the profiled strip comes to rest when the plug-in section is inserted. Each profile connector is thus formed in several parts and comprises at least the first connecting leg, the second connecting leg and, if appropriate, elements designed as separate components for forming the axis of rotation (s).

The mounting position is predetermined by the arrangement of the connecting legs at a 90 ° angle to one another, the connecting legs being arranged in the mounting position in a plane that is spanned by the connecting legs arranged at right angles to one another.

In each of the two connecting legs, a receiving channel, in particular with an identical cross-sectional configuration, is formed, the receiving channels being designed and arranged in such a way that they are arranged relative to one another in the mounting position such that the separate fixing element can be inserted into both receiving channels by a linear movement. The profile connector is fixed in its mounting position by the fixing element.

The receiving channels are in particular designed such that they completely surround the fixing element in the inserted state in the circumferential direction of the fixing element, the fixing element preferably abutting one or all walls of the receiving channels without a gap, so that the fixing element is held in the receiving channels by a non-positive connection.

In particular, it can be provided that the fixing element can be introduced into the first receiving channel via an edge of the first connecting leg. In this case, a cutout is formed in the edge of the first connecting leg, which guides the fixing element during insertion into the first receiving channel.

The receiving channels are preferably each formed in a section of the respective connecting leg that cannot be inserted into a profile strip, for example in the corner section. However, it can very well be provided that, in order to increase the stability, the fixing element in the assembled position extends beyond at least one receiving channel into an insertion section of the connecting leg.

The fixing element is formed in particular from a rod-shaped, preferably flat element, the outer cross-sectional configuration of the fixing element pushed into the receiving channels corresponding to the inner cross-sectional configuration of the receiving channels.

The fixing element is preferably designed as a one-piece suspension element which has a fixing section which can be introduced into the receiving channels, a connecting section which projects approximately at right angles to the plane spanned by the connecting legs, and an end section which is aligned approximately parallel to the plane. When using the profile connector with a frame for a window insect protection device, the end section engages behind a window frame.

In particular, it is provided that a latching element is formed on the first connecting leg and a latching element complementary to the first latching element is formed in one piece on the second connecting leg, so that the connecting legs latch together in the assembly position. The latching element can, for example, have a particularly hook-shaped projection, which in the assembly position engages behind a corresponding complementary undercut on the second connecting leg. In this way, a further securing can be provided, by means of which the connecting legs are secured in the assembly position against unintentional pivoting back.

So that the profile connectors in the assembly position give the frame a high degree of stability, it can be provided that the first connecting leg of a profile connector has a stability element that projects in particular from its corner section in the starting position in the direction of the second connecting leg, which in the mounting position with the second connecting leg of the profile connector overlaps. The stability element, which projects in particular in one piece on the profile connector, is received in particular in a corresponding recess in the second connecting leg. In particular, it can be provided that at least one locking element is formed on the stability element.

The hinge between two connecting legs of each profile connector has in particular exactly two axes of rotation, of which one axis of rotation is formed in or on the first connecting leg and the second axis of rotation is formed in or on the second connecting leg. The axes of rotation of each swivel joint aligned parallel to one another are connected to one another via at least one connecting element.

In one embodiment, the axes of rotation of the swivel joints are aligned orthogonally to the plane.

Alternatively, the at least one axis of rotation of the profile connector can be aligned parallel to the plane or can be arranged in the plane. The axes of rotation of these swivel joints are aligned in particular at an angle of 45 degrees to the direction of extension of the connecting legs.

In order to additionally fix the profile connectors in their mounting position and to prevent them from swiveling back unintentionally, it can be provided that in the mounting position a cover cap can be inserted into the profile connectors, which secure the connecting legs of the respective profile connector against pivoting. These cover caps are in particular flat and connected to both connecting legs of the profile connector. For this purpose, the cover caps can be positively attached to the profile connector, for example by means of a snap-in connection. The cover cap can also be non-positively attached to the profile connector. The respective profile connector is additionally statically fixed by the cover cap, thus forming a stable unit.

• mindestens vier erfindungsgemäße Profilverbinder,
• mindestens zwei vertikale Rahmenstreben, die jeweils mindestens eine Außenprofilleiste und mindestens eine teleskopierbar mit einer Einschubtiefe in die Außenprofilleiste(n) eingeschobene Innenprofilleiste aufweisen,
• mindestens zwei horizontale Rahmenstreben, die jeweils mindestens eine Außenprofilleiste und mindestens eine teleskopierbar mit einer Einschubtiefe in die Außenprofilleiste(n) eingeschobene Innenprofilleiste aufweisen,

wobei der erste Verbindungsschenkel zumindest abschnittsweise in eine Profilleiste einer vertikalen Rahmenstrebe eingesteckt ist und der zweite Verbindungsschenkel zumindest abschnittsweise in eine Profilleiste einer horizontalen Rahmenstrebe eingesteckt ist, und wobei die Profilverbinder derart angeordnet sind, dass in einer Ausgangsstellung die vertikalen Rahmenstreben und die horizontalen Rahmenstreben parallel zueinander ausgerichtet sind und dass der Rahmen durch Verschwenken der Rahmenstreben zueinander um die Drehachsen der Drehgelenke der jeweils zwei Rahmenstreben miteinander verbindenden Profilverbinder in eine Montagestellung überführbar ist, in der die horizontalen Rahmenstreben und die vertikalen Rahmenstreben in einer Rahmenebene in einem rechten Winkel zueinander angeordnet sind.The profile connector is provided in particular for a frame, preferably for a protective device for use with a building opening, the frame comprising:

• at least four profile connectors according to the invention,
• at least two vertical frame struts, each having at least one outer profile strip and at least one telescopic insert with an insertion depth into the outer profile strip (s),
• at least two horizontal frame struts, each with at least one outer profile strip and at least one telescopic have an inner profile bar inserted into the outer profile bar (s) with a insertion depth,

wherein the first connecting leg is at least partially inserted into a profile bar of a vertical frame strut and the second connecting leg is at least partially inserted into a profile bar of a horizontal frame strut, and wherein the profile connectors are arranged such that in a starting position the vertical frame struts and the horizontal frame struts are parallel to one another are aligned and that the frame can be transferred to a mounting position by pivoting the frame struts relative to one another about the axes of rotation of the swivel joints of the respective profile connectors connecting two frame struts, in which the horizontal frame struts and the vertical frame struts are arranged at right angles to one another in a frame plane.

It is therefore provided that the frame struts preassembled via the profile connectors can be made available to the end user in a compact starting position. The end user then only has to fold the frame from its initial position into the assembly position, the frame in the assembly position being easily adaptable to different sizes of the building opening by telescoping the inner profile strips and outer profile strips to one another. In the following, the end user then only has to fix the frame adapted to the building opening with the corresponding insertion depth of the inner profile strip and outer profile strip and attach the insect protection net to the frame.

It should be noted that the terms "horizontal" and "vertical" refer to an orientation of the frame in a vertical plane for use with a door or a window. If the frame is used with a light well cover, all frame struts are in one arranged substantially horizontal plane, so that the frame struts referred to in the application as vertical frame struts are arranged in the horizontal plane, but still at a right angle to the frame struts referred to as horizontal frame struts.

At least two opposite frame struts and thus parallel in the assembly position each have at least one outer profile strip and one inner profile strip that can be telescoped to the outer profile strip. However, the frame struts can also have, for example, two outer profile strips and one inner profile strip that can be telescoped into both outer profile strips or two inner profile strips and telescopic outer profile strip that can be telescoped to both inner profile strips. The inner profile strip is inserted into the outer profile strip over a length referred to as insertion depth, the insertion depth being able to be changed by the end user until the insertion depth is finally determined. In order to be able to be telescoped, the inner contour of the outer profile strip is in particular complementary to the outer contour of the inner profile strip.

Such a rectangular frame (section) thus has four frame struts, two of which are each connected to a profile connector, the diagonally opposite profile connectors, i.e. the profile connectors not connected to the same frame strut, having an axis of rotation that is orthogonal to that of the frame struts in the assembly position stretched frame level are aligned. In this context, it is provided that the other two, also diagonally opposite, profile connectors have axes of rotation which are aligned parallel to the frame plane in the assembly position or are arranged in the frame plane. The axes of rotation of these swivel joints are aligned in particular at an angle of 45 degrees to the direction of extension of the frame struts connected to the profile connector.

With such an arrangement, it is possible that two pairs of frame struts arranged parallel to one another in the starting position can first be converted into an intermediate position by pivoting about the axes of rotation of two profile connectors oriented orthogonally to the frame plane, in which the two pairs of parallel frame struts are in a right one At an angle to each other, the frame struts can be transferred from the intermediate position into the assembly position by pivoting two pairs of frame struts, which are arranged at right angles to one another in the intermediate position, about the axes of rotation of two profile connectors arranged parallel to or in the plane of the frame.

In other words, the frame struts, which are arranged parallel to one another in the starting position, are first brought into a right-angled arrangement by a pivoting movement, in that the frame struts are pivoted about the axes of rotation arranged orthogonally to the frame plane. The frame is then unfolded further in that the frame struts are pivoted about the axes of rotation arranged in the plane of the frame, the profile connectors already arranged at right angles to one another (and the axes of rotation oriented orthogonally to the plane of the frame), which in the intermediate position were still arranged adjacent to one another , are moved to the diagonally opposite sides of the unfolded frame. One of the profile connectors already arranged at right angles to one another in the intermediate position thus describes a kind of circular arc movement from the intermediate position into the mounting position.

Frames for insect protection devices generally have on the side facing the building and on a section facing the frame exterior a sealing element, such as brush seals. So that such a seal also takes place in the area of the corners and thus in the area of the profile connector, in particular the corner areas of the connecting legs of a profile connector can each have a receiving groove extending along the connecting leg for receiving sealing elements. So that the sealing element can also be easily inserted into the receiving groove in the mounting position, it is provided that the receiving groove of the first connecting leg in the mounting position is open on its end face to a frame exterior and the receiving groove of the second connecting leg is closed on the face side by the first connecting leg in the mounting position . Thus, the sealing element can only be inserted into the frame strut from one side into the respective frame strut via the receiving groove open to the outside of the frame, while on the opposite side the introduction of a sealing element is limited by the receiving groove closed by means of the second connecting leg.

Various means can be provided with which the inner profile strip and the outer profile strip of a frame strut can be fixed to one another at a insertion depth predetermined by the size of the building opening.

The frame can not only be used to stretch a flat insect protection net, but also as a frame for a pleated insect protection net. For this purpose, at least the inner profile strip and the outer profile strip of the vertical frame struts for receiving a pleated blind have an opening that runs along their direction of extension and faces an interior of the frame. An edge of the pleated blind can thus be arranged within the vertical frame struts, the pleated blind extending up to and into the opposite vertical frame strut. In one embodiment, the frame is intended for use as an insect protection device for a window, in which case the frame consists in particular of two lateral vertical frame struts and of a lower and an upper horizontal frame strut, the profile connectors being designed as corner connectors, each with exactly two connecting legs which can be pivoted relative to one another are. Such a frame can be attached to a window frame by means of the hanging elements already described above.

The proposed frame can also be provided for a door opening, in which case the frame can be attached to a door frame, for example by means of hinges. In this case, the frame consists in particular of four lateral frame struts and of a lower, a middle and an upper horizontal frame strut, the middle frame strut being connected at both ends by means of a profile connector designed as a middle connector to two vertical frame struts, the middle connector each having three has pivotable connecting legs.

An insect protection device is also proposed which comprises a frame according to the invention and an insect protection net which is movably attached to or in the frame in the case of a pleated blind.

In the Figures 1 to 3 a first profile connector is shown. The profile connector comprises a first connecting leg 7 and a second connecting leg 8. The connecting legs 7, 8 each have an insertion section 18 and a corner section 19. The connecting legs 7, 8 can each be inserted with the insertion section 18 into a profile strip.

A swivel joint 11 is formed between the corner sections 19 and has an axis of rotation 9. The axis of rotation 9 is oriented orthogonally to a plane spanned by the connecting legs 7 and 8.

A first receiving channel 21 is formed in the first connecting leg 7 and is aligned with a recess at the lower edge of the first connecting leg 7.

The second connecting leg 8 has a second receiving channel 22.

In the Figures 1 to 3 a fixing element 23 is also shown, which forms a suspension element.

From the in Figure 1 Starting position shown, the connecting legs 7 and 8 can be pivoted to each other about the axis of rotation 11 and into the in Figure 2 shown assembly position are transferred. In the in the Figure 2 In the mounting position shown, the first connecting channel 21 of the first connecting leg 7 and the second connecting channel 22 of the second connecting leg 8 are arranged in alignment with one another, so that the fixing element 23 can be introduced into both receiving channels 21, 22 by a linear movement. In the in Figure 3 In the position shown, the fixing element 23 fixes the connecting legs 7 and 8 in their mounting position, since a relative movement of the connecting legs 7, 8 is no longer possible due to the fixing element 23 introduced into the receiving channels 21, 22. In the in Figure 3 shown mounting position, the connecting legs 7, 8 on one level, the connecting legs 7, 8 being arranged in this level.

In the Figures 4 to 6 A further profile connector is shown, the axis of rotation 10 of the swivel joint 11 being aligned within or parallel to the plane spanned by the connecting legs 7 and 8 in the assembly position. The relative pivoting movement of the connecting legs 7, 8 from the in Figure 4 shown starting position in the in Figures 5 and 6 The assembly position shown does not take place within the plane in which the connecting legs 7 and 8 are arranged in the assembly position. Rather, there is a pivoting movement about an axis which is arranged parallel or in the plane.

In addition, the connecting limbs 7 and 8 also have a first receiving channel 21 and a second receiving channel 22, respectively, which are shown in FIG Figures 5 and 6 shown assembly position are aligned with each other.

The one in the following Figures 7 to 11 shown frame has profile connectors, which differ in detail from the profile connectors of the Figures 1 to 6 differentiate. However, the profile connectors of the in the Figures 7 to 11 shown frame on axes of rotation, which are either arranged orthogonally to the plane spanned by the profile connectors in the assembly position or are arranged in or parallel to this plane. In this respect, the in the Figures 1 to 6 Profile connector shown in the Figures 7 to 11 Replace the shown profile connector without further ado.

The one in the Figures 7 to 11 The frame shown comprises a first vertical frame strut 1.1 and a second vertical frame strut 1.2 and a first horizontal frame strut 2.1 and a second horizontal frame strut 2.2. The one in the Figures 7 and 11 in its assembled position, the frame shown in perspective spans a frame plane.

The frame struts 1.1, 1.2, 2.1 and 2.2 each consist of an outer profile strip 3 and an inner profile strip 4. The inner profile strips 4 and the outer profile strips 3 are each telescopic to one another, so that the size of the frame (length of the frame struts) can be easily adapted to windows of different sizes can, an insect protection net, not shown, can be attached to the frame fixed in size.

The outer profile strip 3 of the first vertical frame strut 1.1 is connected to the inner profile strip 4 of the first horizontal frame strut 2.1 via a first profile connector 6.1 with axes of rotation 10 aligned parallel to the frame plane, a first connecting leg 7 of the profile connector 6.1 being inserted into the outer profile strip 3 of the first vertical frame strut 1.1 is inserted and a second connecting leg 8 of the first profile connector 6.1 in the inner profile bar 4 of the first horizontal frame strut 2.1 is inserted. A second profile connector 6.2 with a joint 11 having two axes of rotation 10 aligned parallel to the frame plane connects the inner profile strip 4 of the second horizontal frame strut 2.2 to the outer profile strip 3 of the second vertical frame strut 1.2.

A first profile connector 5.1 with a swivel joint 11 which has two axes of rotation 9 arranged orthogonally to the frame plane connects with its first connecting leg 7 and its second connecting leg 8 the inner profile strip 4 of the first vertical frame strut 1.1 to the outer profile strip 3 of the second horizontal frame strut 2.2. A second profile connector 5.2 with a swivel joint 11, which also has two axes of rotation 9 arranged orthogonally to the frame plane, also connects the outer profile strip 3 of the first horizontal frame strut 2.1 to the inner profile strip 4 of the second vertical frame strut 1.2.

A profile connector with axes of rotation 9 arranged orthogonally to the frame plane, as used as first profile connector 5.1 and second profile connector 5.2, is shown in FIGS Figures 12 and 13 presented in detail. The profile connector comprises a first connecting leg 7 and a second connecting leg 8. The connecting legs 7 and 8 each have an insertion section 18 which is inserted into a profile strip of the frame strut. The connecting legs 7 and 8 also each have a corner section 19 which protrudes beyond the profile strips. An axis of rotation 9 is formed on each of the corner sections 19, which are oriented orthogonally to the frame plane and which are connected to one another via a connecting element 20. On the first connecting leg 7 of the profile connector shown in Figure 12, a hook-shaped locking element 12 and a stability element 14 is also formed, while on the second connecting leg 8 a complementary locking element 13 in the form of a Undercut and a complementary stability element 15 are formed in the form of a recess.

At the in Figure 12 Starting position shown, the insertion portions 18 of the first connecting leg 7 and the second connecting leg 8 are aligned parallel to each other. The profile connector can be swiveled by pivoting the first connecting leg 7 and the second connecting leg 8 about the joint 11 formed with the two orthogonal axes of rotation 9 into FIG Figure 13 shown position are transferred, in which the insertion portions 18 and thus the connecting legs 7 and 8 are arranged at a right angle to each other. In this position, the hook-shaped locking element 12 engages in the complementary locking element 13 formed by an undercut, while the stability element 14, formed as a projection, of the first connecting leg 7 engages in the complementary stability element 15, which is designed as a recess. Thus, the profile connector is secured on the one hand against unintentional pivoting back by means of the locking element 12 and the complementary locking element 13 and on the other hand stably aligned by means of the stability element 14 and the complementary stability element 15.

The one in the Figures 14 to 16 The illustrated profile connector also has a first connecting leg 7 and a second connecting leg 8, each with an insertion section 18 and a corner section 19. The first connecting leg 7 and the second connecting leg 8 are connected to one another via a swivel joint 11, an axis of rotation 10 oriented parallel to the frame plane being formed in the first connecting leg 7 and a second axis of rotation 10 oriented parallel to the frame plane being formed in the second connecting leg 8. The axes of rotation 10 are connected to one another via a connecting element 20. On the first connecting leg 7, a stability element 14 is also formed with a hook-shaped latching element 12 formed thereon, while a complementary stability element in the form of a recess and a complementary latching element 13 in the form of an undercut are formed on the second connecting leg 8.

In the in Figure 14 Starting position shown, the insertion portions 18 of the connecting legs 7 and 8 are aligned parallel to each other. The connecting legs 7 and 8 can be pivoted about the two axes of rotation 10 (see Figure 9 ) in the in Figure 16 shown position are brought in which the insertion portions 18 and thus the connecting legs 7 and 8 are arranged at a right angle to each other. In the in Figure 16 shown position, the hook-shaped locking element 12 engages behind the undercut as a complementary locking element 13, so that this profile connector is also secured against unintentional pivoting back. In addition, the stability element 14 of the first connecting leg 7 overlaps the complementary stability element 15 of the second connecting leg 8, so that in FIG Figure 16 position shown high stability is given.

From the Figures 12 to 16 It can also be seen that the respective first connecting leg 7 has a receptacle 16 into which a hanging element (not shown) can be inserted, the hanging element being easily fixable to the profile connector in different insertion positions due to the resilient design of a latching hook, so that a simple adjustment of the hanging element to the depth of a window frame to which the frame is to be attached is possible. Since the profile connectors shown in FIGS. 12 to 16 have no receiving channels, In this aspect, they do not fall under the invention. However, the profile connectors have features that can be readily transferred to a profile connector according to the invention.

It is now possible to use the frame struts 1.1, 1.2, 2.1 and 2.2 in the Figure 8 shown starting position to be arranged parallel to each other, while each profile connector 5.1, 5.2, 6.1 and 6.2 with its two connecting legs 7, 8 is inserted into a profile strip of two frame struts. The frame can thus be delivered pre-assembled in a very compact condition.

In order to then unfold the frame from the initial position into an assembly position, first the first vertical frame strut 1.1 and the first horizontal frame strut 2.1 together become the second vertical frame strut 1.2 and the second horizontal frame strut 2.2 about the axes of rotation 9 of the profile connectors oriented orthogonally to the frame plane 5.1 and 5.2 in the in Figure 9 shown intermediate position pivoted. In the intermediate position shown in FIG. 9, the pair of frame struts consisting of the first vertical frame strut 1.1 and the first horizontal frame strut 2.1 is arranged at a right angle to the pair of frame struts consisting of the second vertical frame strut 1.2 and the second horizontal frame strut 2.2, wherein the profile connectors 5.1 and 5.2 in the in Figure 13 shown state.

In the following (see Figure 10 ) the second vertical frame strut 1.2 is then pivoted together with the first horizontal frame strut 2.1 to the first vertical frame strut 1.1 and the second horizontal frame strut 2.2 about the axes of rotation 10 of the profile connectors 6.1 and 6.2 arranged parallel to the frame plane until all frame struts 1.1, 1.2, 2.1 and 2.2 are arranged in a plane in which the vertical frame struts 1.1 and 1.2 are arranged parallel to each other and at right angles to the horizontal frame struts 2.1 and 2.2. This position, also referred to as the mounting position, is shown in Figure 11 shown. From the in Figure 11 In the assembly position shown, the frame can be adapted to the size of a window frame by simply pulling it apart, the outer profile strips 3 and inner profile strips 4 being telescoped to one another.

With the present invention, it is possible to provide the end user with a pre-assembled frame in a compact manner, the end user then only having to unfold the frame. The telescopic profile strips can then be easily resized.

From the Figure 8 it can also be seen that the corner sections 19 of the connecting legs 7 and 8 each have a receiving groove 17.1 and 17.2, respectively, the first receiving groove 17.1 also being accessible from a frame exterior in the mounting position, so that sealing elements can be inserted directly into the first receiving groove 17.1 and in The following can be inserted in corresponding grooves in the profile strips. The second receiving grooves 17.2, on the other hand, are closed on the front side in the assembly position by the other connecting leg, so that a definite end stop is specified when inserted.
