[0038] FIG. 7: shows the profile connector according to FIG. 6 in the assembly position,

[0039] FIG. 8: shows a profile connector with axes of rotation oriented parallel to the frame plane in the initial position,

[0040] FIG. 9: shows the profile connector according to FIG. 8 when transferred from the intermediate position into the assembly position and

[0041] FIG. 10: shows the profile connector according to FIG. 8 in the assembly position.

[0042] The frame shown in FIGS. 1 to 5 comprises a first vertical frame strut 1.1 and a second vertical frame strut 1.2 as well as a first horizontal frame strut 2.1 and a second horizontal frame strut 2.2 The frame shown in perspective in FIGS. 1 and 5 in its assembly position spans a frame plane.

[0043] The frame struts 1.1, 1.2, 2.1 and 2.2 in each case consist of an outer profile strip 3 and an inner profile strip 4. The inner profile strips 4 and the outer profile strips 3 in each case are telescopable relative to one another so that the size of the frame (length of the frame struts) may be adapted in a simple manner to various sizes of window, wherein an insect protection net, not shown, may be fastened to the frame which is fixed to a size.

[0044] 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 oriented parallel to the frame plane, wherein a first connecting arm 7 of the profile connector 6.1 is inserted into the outer profile strip 3 of the first vertical frame strut 1.1 and a second connecting arm 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 oriented 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.

[0045] A first profile connector 5.1 with a rotational joint 11 having two axes of rotation 9 arranged at right angles to the frame plane connects 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, by means of its first connecting arm 7 and its second connecting arm 8. A second profile connector 5.2, with a rotational joint 11 also having two axes of rotation 9 arranged at right angles to the frame plane, additionally 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.

[0046] A profile connector with axes of rotation 9 arranged at right angles to the frame plane, is shown in FIGS. 6 and 7 in detail as inserted as a first profile connector 5.1 and a second profile connector 5.2. The profile connector comprises a first connecting arm 7 and a second connecting arm 8. The connecting arms 7 and 8 in each case have an insertion portion 18 which is inserted into a profile strip of the frame strut. The connecting arms 7 and 8 additionally have in each case a corner portion 19 which protrudes over the profile strips. An axis of rotation 9 is configured in each case on the corner portions 19, said axes of rotation being oriented at right angles to the frame plane and being connected together via a connecting element 20.

[0047] Additionally a hook-shaped latching element 12 and a stabilising element 14 are configured on the first connecting arm 7 of the profile connector shown in FIG. 6, whilst a complementary latching element 13 in the form of an undercut and a complementary stabilising element 15 in the form of a recess are configured on the second connecting arm 8.

[0048] In the initial position shown in FIG. 6 the insertion portions 18 of the first connecting arm 7 and of the second connecting arm 8 are oriented parallel to one another. By pivoting the first connecting arm 7 and the second connecting arm 8 about the joint 11 which is configured with the two axes of rotation 9 at right angles, the profile connector may be transferred into the position shown in FIG. 7 in which the insertion portions 18 and thus the connecting arms 7 and 8 are arranged at a right angle to one another. In this position, the hook-shaped latching element 12 engages in the complementary latching element 13 configured by an undercut, whilst the stabilising element 14 of the first connecting arm 7 which is configured as a projection engages in the complementary stabilising element 15 which is configured as a recess. Thus the profile connector firstly is secured against being inadvertently pivoted back by means of the latching element 12 and the complementary latching element 13, and secondly is oriented in a stable manner by means of the stabilising element 14 and the complementary stabilising element 15.

[0049] The profile connector shown in FIGS. 8 to 10 also has a first connecting arm 7 and a second connecting arm 8 with in each case an insertion portion 18 and a corner portion 19. The first connecting arm 7 and the second connecting arm 8 are connected together via a rotational joint 11, wherein an axis of rotation 10 oriented parallel to the frame plane is configured in the first connecting arm 7 and a second axis of rotation 10 oriented parallel to the frame plane is configured in the second connecting arm 8.

[0050] The axes of rotation 10 are connected together via a connecting element 20. Additionally a stabilising element 14 with a hook-shaped latching element 12 configured thereon is configured on the first connecting arm 7, whilst a complementary stabilising element in the form of a recess and a complementary latching element 13 in the form of an undercut are configured on the second connecting arm 8.

[0051] In the initial position shown in FIG. 8 the insertion portions 18 of the connecting arms 7 and 8 are oriented parallel to one another. The connecting arms 7 and 8 may be moved by pivoting about the two axes of rotation 10 (see FIG. 9) into the position shown in FIG. 10, in which the insertion portions 18 and thus also the connecting arms 7 and 8 are arranged at a right angle to one another. In the position shown in FIG. 10 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 being inadvertently pivoted back. Additionally the stabilising element 14 of the first connecting arm 7 overlaps the complementary stabilising element 15 of the second connecting arm 8, so that a high degree of stability is provided in the position shown in FIG. 10.

[0052] From FIGS. 6 to 10, it may also be identified that the respective first connecting arm 7 has a receiver 16, a suspension element (not shown) being able to be inserted therein, wherein, due to the resilient configurations of a latching hook, the suspension element may be fixed in a simple manner on the profile connector at different insertion positions so that a simple adaptation is possible of the suspension element to the depth of a window frame to which the frame is intended to be fastened.

[0053] It is thus possible to arrange the frame struts 1.1, 1.2, 2.1 and 2.2 parallel to one another in the initial position shown in FIG. 2, whilst each profile connector 5.1, 5.2, 6.1 and 6.2 with its two connecting arms 7, 8 in each case is already inserted into a profile strip of two frame struts. Thus, the frame may be shipped preassembled in a very compact state.

[0054] In order to unfold the frame from the initial position into an assembly position, therefore, firstly the first vertical frame strut 1.1 and the first horizontal frame strut 2.1 are pivoted together with 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 5.1 and 5.2 oriented at right angles to the frame plane, into the intermediate position shown in FIG. 3. In the intermediate position shown in FIG. 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, wherein the profile connectors 5.1 and 5.2 are in the state shown in FIG. 7.

[0055] Subsequently (see FIG. 4), therefore, the second vertical frame strut 1.2 together with the first horizontal frame strut 2.1 are then pivoted relative 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 of the frame struts 1.1, 1.2, 2.1 and 2.2 are arranged in one plane in which the vertical frame struts 1.1 and 1.2 are arranged parallel to one another and at a right angle to the horizontal frame struts 2.1 and 2.2. This position, which is also denoted as the assembly position, is shown in FIG. 5.

[0056] From the assembly position shown in FIG. 5, the frame may be adapted to the size of a window frame by simply being pulled apart, wherein the outer profile strips 3 and the inner profile strips 4 are telescoped relative to one another.

[0057] It is possible by means of the present invention to provide the end user with a preassembled frame in a compact manner, wherein the end user subsequently only has to unfold the frame. An adaptation of the size may thus be carried out in a simple manner due to the telescopable profile strips.

[0058] From FIG. 2 it may further be identified that the corner portions 19 of the connecting arms 7 and 8 in each case have a receiving groove 17.1 and/or 17.2, wherein the first receiving groove 17.1 is accessible from a frame exterior even in the assembly position, so that sealing elements are able to be directly inserted into the first receiving groove 17.1 and subsequently may be inserted into corresponding grooves in the profile strips. The second receiving grooves 17.2, however, are closed on the front face by the other connecting arm in the assembly position, so that during an insertion process a definitive end stop is predetermined.
