Description

The present invention relates to a profile connector, comprising at least one first connection leg that can be inserted into a profile strip and one second connection leg that can be inserted into a profile strip. The invention also relates to a frame of a protective device, such as insect protection device or light shaft 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 strip, as well as at least two horizontal frame struts, each having at least one outer profile strip and at least one telescopic inner profile strip pushed into the outer profile strip with an insertion depth, the first connecting leg being at least partially inserted into a profile strip of a vertical frame strut and the second connecting leg being at least partially inserted into a profile strip 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 ability of the inner profile strips and outer profile strips of the frame struts.

A frame with the aforementioned features is made, for example EP 3 138 990 B1 known. The components of such a frame are usually made available to the end user as a kit, so that the end user must first assemble the components before an insect screen 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 with the aid of a tool, if necessary. In order to reduce the associated assembly effort, is off, for example 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 profile strip pairs, which are arranged at right angles to one another and connected to one another via a corner connector, span a large area. In addition, with this solution, the end user still has to insert the preassembled profile strips into profile strips of other preassembled profile strip pairs BE 763 611 A and GB 2 329 930 A disclose further profile connectors.

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

The object is achieved 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, with individual features of the advantageous further developments being able to be combined with one another in a technically meaningful way.

The object is achieved in particular by a profile connector with the features mentioned at the outset, 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 rotary joint into an assembly position in which the first connecting leg and the second connecting leg in a plane at a right angle to each other are arranged, and the first connecting leg has a first receiving channel and the second connecting leg has a second receiving channel, wherein the first receiving channel and the second receiving channel are aligned in the assembly position, and in which a separate fixing element is provided, the fixing element in the assembly 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 hinge-like indirectly or directly connected to one another 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 right angles to each other, wherein at least the two connecting legs are secured by inserting the fixing element into the two receiving channels in the assembly position, so that pivoting the connection legs back out of the assembly 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 can be fixed in the profile strip in a non-positive and / or form-fitting manner. For this purpose, the outer circumferential design of the insertion section can match the inner cross-sectional profile of a profile strip, so that the insertion section can be inserted into the corresponding profile strip. In addition, each connecting leg can in particular have a corner section protruding beyond the profile strip and thus arranged outside the profile strip, in particular formed 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 profile 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 necessary, elements formed as separate components for forming the axis of rotation (s).

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

In each of the two connecting legs, a receiving channel with an identical cross-sectional configuration, in particular, is formed, the receiving channels being designed and arranged in such a way that they are arranged in relation to one another in the assembly position so that the separate fixing element can be introduced into both receiving channels by a straight movement. The profile connector is fixed in its assembly 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 resting against one or all of the walls of the receiving channels without a gap, so that the fixing element is held in the receiving channels by a non-positive connection.

It can in particular 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 recess is formed in the edge of the first connecting leg which guides the fixing element into the first receiving channel during introduction.

The receiving channels are preferably each formed in a section of the respective connecting leg which 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 mounted 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 design of the receiving channels.

The fixing element is preferably designed as a one-piece suspension element, which has a fixing section that can be introduced into the receiving channels, a connecting section protruding approximately at right angles to the plane spanned by the connecting legs, and an end section oriented 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 frame of the window.

In particular, it is provided that a latching element is formed in one piece 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 with one another 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 safeguard can be provided, by means of which the connecting legs are secured against inadvertent pivoting back in the assembly position.

In order for the profile connector to give the frame a high level of stability in the assembly position, it can be provided that the first connection leg of a profile connector has a stability element which protrudes from its corner section in the starting position in the direction of the second connection leg and which in the assembly position with the second connection leg of the profile connector overlaps. The stability element protruding in particular in one piece from the profile connector is received in particular in a corresponding recess in the second connecting leg. It can in particular be provided here that at least one latching element is formed on the stability element.

The swivel joint 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, which are 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 oriented orthogonally to the plane.

Alternatively, the at least one axis of rotation of the profile connector can be aligned parallel to the plane or 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 connector in its assembly position and to secure it against unintentional pivoting back, it can be provided that a cover cap can be inserted into the profile connector in the assembly position, which cap secures the connecting legs of the respective profile connector against pivoting. These cover caps are therefore particularly flat and are connected to both connecting legs of the profile connector. For this purpose, the cover caps can be fixed in a form-fitting manner on the profile connector, for example by means of a latching connection. The cover cap can also be fastened to the profile connector in a non-positive manner. The respective profile connector is also 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 the following:

• at least four profile connectors according to the invention,
• at least two vertical frame struts, each of which has at least one outer profile strip and at least one inner profile strip inserted telescopically with an insertion depth into the outer profile strip (s),
• at least two horizontal frame struts, each of which has at least one outer profile strip and at least one telescopic have inner profile strips pushed into the outer profile strip (s) with an insertion depth,

wherein the first connecting leg is at least partially inserted into a profile strip of a vertical frame strut and the second connecting leg is inserted at least partially into a profile strip of a horizontal frame strut, and the profile connectors are arranged in such a way that in an initial position the vertical frame struts and the horizontal frame struts are parallel to one another are aligned and that the frame can be transferred into an assembly position by pivoting the frame struts to each other about the axes of rotation of the swivel joints of the two frame struts connecting profile connectors in which the horizontal frame struts and the vertical frame struts are arranged in a frame plane at a right angle to each other.

It is therefore provided that the frame struts preassembled via the profile connector 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 starting position into the assembly position, the frame being easily adaptable to different sizes of the building opening in the assembly position by telescoping the inner profile strips and outer profile strips with respect 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 screen to the frame.

It should be noted that the terms "horizontal" and "vertical" refer to orienting the frame in a vertical plane for use with a door or window. If the frame is used with a light well cover, all frame struts are in one arranged essentially horizontal plane, so that the frame struts referred to in the application as vertical frame struts are also 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, which are therefore parallel in the assembly position, each have at least one outer profile strip and an inner profile strip that can be telescoped to the outer profile strip. The frame struts can, for example, also have two outer profile strips and an inner profile strip that can be telescoped into both outer profile strips or two inner profile strips and outer profile strips that can be telescoped to both inner profile strips. The inner profile strip is pushed into the outer profile strip over a length called the insertion depth, whereby the insertion depth can be changed by the end user until the insertion depth has been finally determined. For the telescopability, 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 connector, i.e. the profile connector 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 spanned frame plane are aligned. In this context, it is provided that the other two profile connectors, also each diagonally opposite, have axes of rotation which, in the assembly position, are aligned parallel to the frame plane 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, which are arranged parallel to one another in the starting position, can initially be transferred into an intermediate position by pivoting around the axes of rotation of two profile connectors, which are aligned orthogonally to the frame plane, in which the two pairs of parallel frame struts in a right one Angle to each other are arranged, wherein in the following the frame struts can be transferred from the intermediate position to the assembly position by pivoting two pairs of frame struts arranged at right angles to each other in the intermediate position about the axes of rotation of two profile connectors arranged parallel to or in the frame plane.

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 to one another by a pivoting movement, in that the frame struts are pivoted about the axes of rotation arranged orthogonally to the frame plane. In the following, the frame is then further unfolded by pivoting the frame struts around the axes of rotation arranged in the frame plane, the profile connectors already arranged at right angles to one another (and having the axes of rotation oriented orthogonally to the frame plane), which were still arranged adjacent to one another in the intermediate position , to be 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 assembly position.

Frames for insect protection devices usually have on the side facing the building and on a section directed towards the outside of the frame 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, 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 assembly position, it is provided that the receiving groove of the first connecting leg is open on its end face to the outside of the frame in the assembly position and the receiving groove of the second connecting leg is closed on the front side by the first connecting leg in the assembly position . Thus, the sealing element can only be inserted 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 an 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 which is continuous along their direction of extension and faces a frame interior. Thus, an edge of the pleated blind can 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 a lower and an upper horizontal frame strut, the profile connectors being designed as corner connectors with exactly two connecting legs that can be pivoted to one another are. Such a frame can be attached to a window frame by means of the suspension elements already described above.

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

An insect protection device is also proposed which comprises a frame according to the invention and an insect protection net 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, which has an axis of rotation 9, is formed between the corner sections 19. The axis of rotation 9 is aligned orthogonally to a plane spanned by the connecting legs 7 and 8.

In the first connecting leg 7, a first receiving channel 21 is formed, which is aligned with a recess on 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 The 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 assembly position shown, the first connection channel 21 of the first connection leg 7 and the second connection channel 22 of the second connection leg 8 are aligned 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 Thus, the fixing element 23 fixes the connecting legs 7 and 8 in their assembly 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 The assembly position shown, the connecting legs 7, 8 span a plane, the connecting legs 7, 8 being arranged in this plane.

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 starting position shown in Figures 5 and 6 The assembly position shown is therefore not 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 legs 7 and 8 also have a first receiving channel 21 and a second receiving channel 22, which in the FIG Figures 5 and 6 mounting position shown are arranged in alignment with one another.

The one in the following Figures 7 to 11 The frame shown has profile connectors that differ in detail from the profile connectors of the Figures 1 to 6 distinguish. However, the profile connectors 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, those in the Figures 1 to 6 Profile connector shown in the Figures 7 to 11 Replace the profile connector shown 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 Frame shown in perspective in its assembled position 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 so that the size of the frame (length of the frame struts) can be easily adapted to different sized windows can, wherein an insect screen (not shown) can be attached to the frame fixed in one 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, with a first connecting leg 7 of the profile connector 6.1 in 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 strip 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 with the outer profile strip 3 of the second vertical frame strut 1.2.

A first profile connector 5.1 with a swivel joint 11 having 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 with the outer profile strip 3 of the second horizontal frame strut 2.2. A second profile connector 5.2 with a swivel joint 11 also having 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 with 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 the first profile connector 5.1 and second profile connector 5.2, is in the Figures 12 and 13 shown in detail. The profile connector comprises a first connection leg 7 and a second connection leg 8. The connection 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 over the profile strips. A rotation axis 9 is formed on each of the corner sections 19, which axes 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 are 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 The initial position shown, the plug-in sections 18 of the first connecting leg 7 and the second connecting leg 8 are aligned parallel to one another. 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, the profile connector can be moved into the position shown in FIG Figure 13 are transferred to the position shown, in which the plug-in sections 18 and thus the connecting legs 7 and 8 are arranged at a right angle to each other. In this position, the hook-shaped latching element 12 engages the complementary latching element 13 formed by an undercut, while the stability element 14 of the first connecting leg 7 formed as a projection engages in the complementary stability element 15 formed as a recess. Thus, on the one hand, the profile connector is secured against unintentional pivoting back by means of the locking element 12 and the complementary locking element 13 and, on the other hand, it is stably aligned by means of the stability element 14 and the complementary stability element 15.

The one in the Figures 14 to 16 The profile connector shown 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, a pivot axis 10 aligned parallel to the frame plane being formed in the first connecting leg 7 and a second pivot axis 10 aligned 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 The starting position shown, the plug-in sections 18 of the connecting legs 7 and 8 are aligned parallel to one another. The connecting legs 7 and 8 can be pivoted about the two axes of rotation 10 (see Figure 9 ) into the in Figure 16 are brought to the position shown, in which the plug-in sections 18 and thus also the connecting legs 7 and 8 are arranged at a right angle to each other. In the in Figure 16 The position shown, 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 the FIG Figure 16 position shown is given a high level of stability.

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 (not shown) suspension element can be inserted, the suspension element being easy to fix on the profile connector in different insertion positions due to the resilient design of a latching hook, so that a simple adaptation of the suspension element to the depth of a window frame is possible to which the frame is to be attached. Since the profile connectors shown in Figures 12 to 16 have no receiving channels, these do not fall under this aspect of the invention. However, the profile connectors have features that can be easily 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 in Figure 8 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 each inserted into a profile strip of two frame struts. The frame can thus be delivered pre-assembled in a very compact state.

In order to then unfold the frame from the starting position into an assembly position, first the first vertical frame strut 1.1 and the first horizontal frame strut 2.1 together to the second vertical frame strut 1.2 and the second horizontal frame strut 2.2 around the axes of rotation 9 aligned orthogonally to the frame plane of the profile connector 5.1 and 5.2 in the in Figure 9 pivoted intermediate position shown. In the intermediate position shown in Figure 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, whereby the profile connectors 5.1 and 5.2 are in the in Figure 13 are in the state shown.

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 form 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, which are 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 known as the assembly position, is in Figure 11 shown. From the in Figure 11 The assembly position shown 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 towards 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. A size adjustment can then be carried out in a simple manner due to the telescopic profile strips.

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, the first receiving groove 17.1 being accessible from the outside of the frame even in the assembly position, so that sealing elements can be introduced directly into the first receiving groove 17.1 and in the The following can be introduced into corresponding grooves in the profile strips. The second receiving grooves 17.2, on the other hand, are closed on the front side by the other connecting leg in the assembly position, so that a definitive end stop is specified when it is pushed in.
