Description

The present invention relates to a frame of a protective device, such as an insect protection device or light well cover, for use with a building opening such as a window or door.

EP 3 138 990 B1 discloses a frame of a protective device for use with a building opening, comprising at least two vertical 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, at least two horizontal frame struts, each having at least one outer profile strip and at least one telescopic with an insertion depth into the outer profile strip, and profile connector, each having at least one first connection leg and a second connection leg, the first connection leg being at least partially inserted into a profile strip of a vertical frame strut and the second connection leg at least partially in a profile strip of a horizontal frame strut is plugged in. 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.

The components of such a frame are usually made available to the end user as a kit, so that the end user the components must first be assembled before an insect screen can be attached to the frame. For this purpose, the end user must, in particular, insert the profile connector 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 pre-assembled profile strips into profile strips of other pre-assembled profile strip pairs.

EP 2 682 558 A2 discloses a securing means for use with a barrier, the disclosed barrier being a frame of a protective device for use with a building opening, which comprises at least two vertical frame struts, two horizontal frame struts and in each case a first connecting leg and a second connecting leg having profile connectors, the horizontal frame struts each have an outer profile strip and an inner profile strip inserted telescopically with an insertion depth into the outer profile strip, each profile connector having a first connecting leg and a second connecting leg, and having a pivot joint having at least one axis of rotation such that in an initial position the vertical frame struts and the horizontal frame struts are parallel are aligned with each other and that the frame by pivoting the frame struts to each other about the axis of rotation of the swivel joints of the two frames treben interconnecting profile connector can be transferred into an assembly position in which the horizontal frame struts and the vertical frame struts are arranged in a frame plane at a right angle to one another. The assembly of such a barrier is complex.

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 frame of a protective device which is more user-friendly and can be assembled with less effort.

The object is achieved by a framework with the features of the independent claim. Advantageous further developments of the frame are specified in the dependent claims and in the description, individual features of the advantageous further developments being able to be combined with one another in a technically meaningful manner.

The object is achieved in particular by a frame with the features mentioned at the beginning, in which each profile connector has a swivel joint with at least one axis of rotation between the connecting legs, which are designed in such a way that the vertical frame struts and the horizontal frame struts in an initial position of the frame are aligned parallel to one another and that the frame can be moved into an assembly position by pivoting the frame struts to one another about the axis of rotation of the swivel joints of the profile connectors connecting two frame struts, in which the horizontal frame struts and the vertical frame struts are arranged in a frame plane at right angles to one another .

The basic idea of the invention provides that the profile connectors are designed in a hinge-like manner, so that the frame struts pre-assembled 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 starting 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. 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 an 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. In the case of using the frame with a light well cover, all frame struts are arranged in a substantially 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 horizontal frame struts designated frame struts. At least two opposite and thus parallel frame struts in the assembly position each have at least one outer profile strip and an inner profile strip telescopic to the outer profile strip. The frame struts can, for example, also have two outer profile strips and one inner profile strip that can be telescoped into both outer profile strips or two inner profile strips each and outer profile strip 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 telescopic ability, the inner contour of the outer profile strip is in particular complementary to the outer contour of the inner profile strip.

The connecting legs of the profile connectors each have, in particular, an insertion section located in the profile strip, which is fixed in the profile strip in a non-positive and / or positive manner. In addition, each connecting leg has in particular a corner section protruding over 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. Each profile connector is thus made in several parts and comprises at least the first connecting leg, the second connecting leg and, if necessary, elements designed as separate components for forming the axis of rotation.

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 on the second connecting leg, so that the connecting legs latch with one another in the assembled 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. To this A first securing device can be provided by means of which the connecting legs are secured against unintentional pivoting back in the assembly position.

So that the profile connectors give the frame a high level of stability in the assembly position, it can be provided that the first connecting 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 be provided here in particular 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, one of which 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 of profile connectors which are diagonally opposite in the assembly position are aligned orthogonally to the frame plane. 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 in particular aligned 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 Angle to each other are arranged, wherein in the following the frame struts from the intermediate position can be transferred into 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 unfolded further by pivoting the frame struts about 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 , on the diagonally opposite sides of the unfolded frame can be moved. One of the profile connectors already arranged at right angles to one another in the intermediate position thus describes a type of circular arc movement from the intermediate position into the assembly position.

In order to fix the profile connector in its assembly position and 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 connected to both connecting legs of the profile connector. For this purpose, the cover caps can be fixable to the profile connector in a form-fitting manner, for example by means of a latching connection. The cover cap can also be fastened to the profile connector with a force fit. The respective profile connector is statically fixed by the cover cap and thus forms a stable unit.

So that the insect protection device can easily be attached to a window frame, the profile connectors each have a receptacle for a suspension element that can be fixed in particular by means of a latching connection. The suspension elements can be fixed to the profile connector in a force-fitting and / or form-fitting manner, in particular without the use of an additional tool. In particular, an L-shaped suspension element is provided, which has regular depressions on its leg that can be pushed into the receptacle, which can be fixed in the receptacle with an elastically deflectable hook element in a non-positive and / or positive manner in positions pushed in at different distances. Such an L-shaped suspension element can thus be easily adapted to different deep window frames.

Frames for insect protection devices generally have a sealing element, such as brush seals, on the side facing the building and on a section facing the outside of the frame. 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 at its end face to the outside of the frame in the assembly position and the receiving groove of the second connecting leg is closed at the end by the first connecting leg in the assembly position . Thus, the sealing element can only be inserted into the frame strut from one side 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.

• Es kann beispielsweise ein sich über die gesamte Länge einer Rahmenstrebe erstreckender Klebestreifen vorgesehen sein, an dessen der Klebeseite abgewandten Oberseite eine Vielzahl (mehr als 10 oder mehr als 100) T-förmiger Rasthaken zum Festlegen eines Insektenschutznetzes ausgebildet sind. Der Klebestreifen hat also eine Doppelfunktion. Er dient zur gegenseitigen Festlegung der Innenprofilleiste und der Außenprofilleiste in einer Einschubtiefe und zum Anbringen des Insektenschutznetzes. Die T-förmigen Rasthaken sind mit ihrem orthogonal zu der Oberseite des Klebestreifens ausgerichteten Stamm insbesondere in mehreren parallel zueinander ausgerichteten Reihen angeordnet. An dem insbesondere parallel zu der Erstreckungsrichtung der Rahmenstrebe ausgebildeten horizontalen Balken des "T" sind an den Enden Häkchen ausgebildet. Insofern kann das Insektenschutznetz klettverschlussartig an dem Klebestreifen befestigt werden.
• Die Einschubtiefe kann auch mittels eines sich über die gesamte Länge der Rahmenstrebe erstreckenden doppelseitigen Klebestreifens festgelegt werden, wobei mit dem doppelseitigen Klebestreifen eine Befestigungsprofilleiste an der Rahmenstrebe befestigt ist. Die Befestigungsprofilleiste weist insbesondere zwei sich entlang der Rahmenstrebe erstreckende und zueinander um eine parallel zur Rahmenstrebe verlaufende Schwenkachse bewegliche Abschnitte auf, die aufeinander geklappt werden können. Die beiden Abschnitte sind insbesondere einteilig ausgebildet, wobei die Schwenkachse durch eine relativ dünne Materialdicke zwischen den Abschnitten realisiert ist. Zum Festlegen im zusammengeklappten Zustand weisen beide Elemente sich insbesondere entlang der Rahmenstrebe erstreckende Formschlusselemente auf, zwischen denen im zusammengeklappten Zustand ein Insektenschutznetz fixiert wird. Hierbei kann insbesondere vorgesehen sein, dass innerhalb der Befestigungsprofilleiste ein weiteres doppelseitiges Klebeband vorgesehen ist, mit welchem das Insektenschutznetz zunächst vorpositionierbar ist, wobei die wesentliche Fixierung des Insektenschutznetzes durch die Formschlusselemente erfolgt.
• Es kann zudem eine an der Innenprofilleiste anbringbare Adapterprofilleiste vorgesehen sein, die auf einen sich entlang der Innenprofilleiste erstreckenden Vorsprung oder in eine sich entlang der Innenprofilleiste erstreckende Nut auf- beziehungsweise eingesteckt wird, wobei ein Außenprofil beziehungsweise ein Innenprofil der Adapterprofilleiste mit einem entsprechenden Profil eines Vorsprungs beziehungsweise einer Nut der Außenprofilleiste fluchtet. Somit kann eine sich über die gesamte Rahmenstrebe erstreckende Klemmleiste auf die Adapterprofilleiste (im Bereich der Innenprofilleiste) und auf den Vorsprung (im Bereich der Außenprofilleiste) aufgestecktt werden. Alternativ wird eine kederförmige Klemmleiste im Bereich der Außenprofilleiste in die Nut der Außenprofilleiste und im Bereich der Innenprofilleiste in eine durch die Adapterprofilleiste vorgegebene Nut eingebracht. Zwischen der Klemmleiste und dem Vorsprung/Nut der Außenprofilleiste und der Adapterprofilleiste im Bereich der Innenprofilleiste kann ein Insektenschutznetz festgeklemmt werden.
• Es kann zudem ein auf einen Abschnitt der der Innenprofilleiste aufgeklebter Streifen (z. B. doppelseitiges Klebeband, Blech- oder Kunststoffstreifen) vorgesehen sein, der zum einen die Einschubtiefe in die benachbarte Außenprofilleiste begrenzt und zum anderen mit seiner Oberseite mit einer angrenzenden Oberfläche der Außenprofilleiste fluchtet, so dass ein weiteres Element (z. B. die oben genannte Befestigungsprofilleiste in einer Ebene über die gesamte Länge der Rahmenstrebe anbringbar ist. Der Streifen hat also eine Dicke, die im Wesentlichen der Wandstärke der Außenprofilleiste entspricht.

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, whereby in these means independent of the solution described above and in particular independent of the profile connectors having the swivel joints standalone solution in combination with a framework described at the beginning:

• For example, an adhesive strip extending over the entire length of a frame strut can be provided, on whose upper side facing away from the adhesive side a large number (more than 10 or more than 100) T-shaped locking hooks are designed to fix an insect protection net. The adhesive strip thus has a double function. It is used to mutually fix the inner profile strip and the outer profile strip at an insertion depth and to attach the insect protection net. The T-shaped latching hooks are arranged with their trunk aligned orthogonally to the upper side of the adhesive strip, in particular in a plurality of rows aligned parallel to one another. On the horizontal bar of the "T", which is in particular parallel to the direction of extent of the frame strut, hooks are formed at the ends. In this respect, the insect protection net can be attached to the adhesive strip like a Velcro fastener.
• The insertion depth can also be determined by means of a double-sided adhesive strip extending over the entire length of the frame strut, a fastening profile strip being attached to the frame strut with the double-sided adhesive strip. The fastening profile strip has in particular two sections which extend along the frame strut and are movable relative to one another about a pivot axis running parallel to the frame strut and which can be folded onto one another. The two sections are in particular formed in one piece, the pivot axis being implemented by a relatively thin material thickness between the sections. For fixing in the folded state, both elements have form-locking elements that extend in particular along the frame strut, between which an insect protection net is fixed in the folded state. In this case, it can be provided in particular that a further double-sided adhesive tape is provided within the fastening profile strip, with which the Insect protection net can first be pre-positioned, the essential fixation of the insect protection net being carried out by the form-fitting elements.
• An adapter profile strip that can be attached to the inner profile strip can also be provided, which is fitted or inserted onto a projection extending along the inner profile strip or into a groove extending along the inner profile strip, an outer profile or an inner profile of the adapter profile strip with a corresponding profile of a projection or a groove in the outer profile strip is aligned. Thus, a terminal strip extending over the entire frame strut can be plugged onto the adapter profile strip (in the area of the inner profile strip) and on the projection (in the area of the outer profile strip). Alternatively, a keder-shaped terminal strip is introduced into the groove of the outer profile strip in the area of the outer profile strip and in the area of the inner profile strip in a groove predetermined by the adapter profile strip. An insect protection net can be clamped between the clamping strip and the projection / groove of the outer profile strip and the adapter profile strip in the area of the inner profile strip.
• In addition, a strip (e.g. double-sided adhesive tape, sheet metal or plastic strip) that is glued to a section of the inner profile strip can be provided which, on the one hand, limits the insertion depth into the adjacent outer profile strip and, on the other hand, with its upper side with an adjacent surface of the outer profile strip is aligned so that a further element (for example the above-mentioned fastening profile strip can be attached in a plane over the entire length of the frame strut. The strip therefore has a thickness which essentially corresponds to the wall thickness of the outer profile strip.

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 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 fastened on or in the frame in the case of a pleated blind.

The one in the Figures 1 to 5 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 1 and 5 The 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 can each be telescoped to one another, 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 is inserted into the inner profile strip 4 of the first horizontal frame strut 2.1. 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 to its first connecting leg 7 and its second connecting leg 8 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 6 and 7 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. A hook-shaped locking element 12 and a stability element 14 are also formed on the first connecting leg 7 of the profile connector shown in FIG. 6, while a complementary locking element 13 in the form of an undercut and a complementary stability element 15 in the form of a recess are formed on the second connecting leg 8.

At the in Figure 6 The initial position shown, the insertion 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 around 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 7 position shown are transferred, in which the Insertion sections 18 and thus the connecting legs 7 and 8 are arranged at right angles to one another. 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 8 to 10 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. A stability element 14 with a hook-shaped locking element 12 formed thereon is also formed on the first connecting leg 7, while a complementary stability element in the form of a recess and a complementary locking element 13 in the form of an undercut are formed on the second connecting leg 8.

In the in Figure 8 The starting position shown, the insertion 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 Rotary axes 10 (see Figure 9 ) into the in Figure 10 are brought 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 the in Figure 10 The position shown, the hook-shaped latching element 12 engages behind the undercut as a complementary latching 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 10 position shown is given a high level of stability.

From the Figures 6 to 10 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.

It is now possible to use the frame struts 1.1, 1.2, 2.1 and 2.2 in the in Figure 2 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 are orthogonal to the second vertical frame strut 1.2 and the second horizontal frame strut 2.2 to the frame plane aligned axes of rotation 9 of the profile connector 5.1 and 5.2 into the in Figure 3 pivoted intermediate position shown. In the intermediate position shown in Figure 3, 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 7 state shown.

In the following (see Figure 4 ) then the second vertical frame strut 1.2 is 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, which are arranged parallel to the frame plane, until all the 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 one another 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 5 shown. From the in Figure 5 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 only having to unfold the frame. A size adjustment can then be done in a simple manner due to the telescopic profile strips.

From the Figure 2 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 have, wherein the first receiving groove 17.1 are accessible from the outside of the frame in the assembly position, so that sealing elements can be introduced directly into the first receiving groove 17.1 and can then 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.
