Kit for a frame

The present invention relates to a kit for a frame, in particular for a frame of an insect protection device, such as an insect protection door, an insect protection window or a light well cover. To form an insect protection device, an insect protection net or grille is attached to the frame, with which the opening spanned by the frame is or can be spanned.

Such frames for insect screens generally have two parallel vertical frame struts and two horizontal frame struts connecting the parallel vertical frame struts, the frame struts being connected at their ends by means of corner connectors. The components (corner connectors, frame struts) are usually provided to the end user as individual parts in a package, so that the end user has to assemble all components himself. If, for example, the frame struts are designed as one-piece profile strips, the end user must shorten the profile strips himself to adapt to the window / door size. So that the length of the frame struts can be more easily attached to the window / Door size can be adjusted, it is also known to form the frame struts from at least one inner profile strip and at least one outer profile strip, which are telescopic to one another.

The corner connector parts of such kits have plug-in sections which are arranged at right angles to one another and which the end user has to insert into a profile strip. In this case, there is only one non-positive connection between the plug-in section of the corner connector and the profile strip in the plug-in direction, so that the mounted frame can have a low level of stability. In addition, after assembly, a corner area of the corner connector is visible between the plug-in sections.

In order to provide an aesthetically more appealing and also more stable frame, DE 10 2015 1 16 588 B4 suggests pre-assembling the inner and outer profile strips in pairs via a corner connector and providing the pre-assembled profile strip pairs as a kit. Since the corner connectors with the profile strips are also secured by a form fit in the insertion direction, greater stability is provided. In addition, the profile strips at the end of the corner connector have a miter cut so that the profile strips of a profile strip pair lie against one another with their miter cuts. The packaging of such a kit has a comparatively large volume due to the rectangular arrangement of the pre-assembled profile strip pairs.

The kits for frames known from the prior art thus either have a large number of parts to be assembled by the end user or a relatively large package.

From US 4,279,288 a frame is known in which two profile strips of a frame assembly are connected to one another via a hinge. The profile strips of adjacent frame assemblies can be telescopically inserted into one another, so that a kit with the features of the preamble of claim 1 is known from US Pat. No. 4,279,288. From DE 10 2015 1 17 643 Al is a frame that can be assembled from many individual parts is known.

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 kit for a frame which is easier to assemble by the end user and whose packaging has the smallest possible volume.

The problem is solved by a kit with the features of the independent claim. Advantageous further developments of the kit are given 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 manner.

The object is achieved in particular by a kit for a frame, preferably for a frame of an insect protection device, with at least two frame assemblies, each frame assembly at least one, preferably at least two or exactly two profile strip (s) (such as inner profile strip and / or outer profile strip) and at least comprises a corner connector part arranged on each profile strip, the profile strips and the corner connector parts of the frame assembly being designed in such a way that the profile strips of all frame assemblies are or can be arranged parallel to one another in an initial position and the frame assemblies can be plugged together to form a rectangular frame, in which two profile strips each Are arranged telescopically to each other.

The basic idea of the invention therefore provides that the kit comprises in particular an even number of (pre-assembled) frame assemblies, with each frame assembly in particular precisely two inner and / or outer profile strips (namely: each frame assembly has either an inner profile strip and an outer profile strip, two inner profile strips or two outer profile strips) or exactly four inner and / or outer profile strips (namely: each frame assembly has two Inner profile strips and two outer profile strips). A corner connector part is also arranged on each profile strip of the frame assembly, for which purpose the corner connector part is either formed in one piece with the profile strip or is preferably connected to the profile strip as a preassembled part with a non-positive and / or positive fit.

It is therefore provided that the corner connector connecting the profile strips arranged at right angles to one another in the final assembled state consists of at least two parts (corner connector parts). As also explained further below, the two corner connector parts can be designed in such a way that, according to the invention, they can be plugged into one another or are connected to one another such that they can pivot, forming a type of hinge.

The profile strips of all frame assemblies can therefore initially be arranged parallel (in alignment or offset) to one another, so that the preassembled frame assemblies can be arranged in a packaging to save space.

For the (final) assembly of the frame, the frame assemblies are plugged together, the corner connector parts of different frame assemblies being plugged into one another.

In addition to the pre-assembled frame assemblies, the kit can include further inner and / or outer profile strips, via which the profile strips of various frame assemblies are telescopically connected to one another during assembly.

After the kit has been put together to form a frame, the size of the frame can easily be changed, for which purpose the inner and outer profile strips of the frame struts are telescoped towards one another. If the frame has the desired size, it can be determined in its size with suitable means (screws, insect screens, fixing strips). The kit according to the invention for a frame therefore not only has a very small number of frame assemblies to be assembled by the end user, but also a very small volume in the starting position.

It can be provided that the frame assemblies each have two profile strips that are pivotably arranged with respect to one another, so that the two profile strips of the frame assembly are arranged parallel (aligned or offset) to one another in the starting position and can be pivoted into a position at right angles to one another before they are plugged together. In this case, it is provided in particular that a corner connector part is arranged on each profile strip, via which the profile strips can be pivoted relative to one another. For this purpose, in particular a pivot axis is formed between the two corner connector parts, around which the profile strips can be pivoted relative to one another. The at least one pivot axis can be arranged in such a way that the profile strips are arranged next to one another in the starting position. Alternatively, the pivot axis can be arranged in such a way that the profile strips are arranged in alignment with one another, in which case the frame assembly has a greater length in the starting position.

In one embodiment it can be provided that the kit has exactly four frame assemblies, the respective two profile strips of which are pivotable relative to one another, the profile strips being designed as inner profile strips and / or outer profile strips. The inner profile strip and the outer profile strip are therefore matched to one another in their outer contour or inner contour in such a way that they can be moved / displaced telescopically with respect to one another.

It is also preferred that the two profile strips of a frame assembly, which are pivotably arranged relative to one another, can be pivoted relative to one another about at least one pivot axis, the pivot axes all being one Frame assemblies having pivot axis are aligned in the final assembly position parallel and in particular orthogonally to the plane spanned by the right-angled frame. The profile strips of the frame assemblies are therefore all pivotable in a plane spanned by the later frame.

The two profile strips are preferably secured in the right-angled position by a fixation. In particular, this fixing acts on the corner connector parts of the frame assemblies which are designed to be pivotable with respect to one another. The corner connector parts can be fixed in their position arranged at right angles to one another, for example, by an external fixing element such as a screw, pin or cover cap.

However, it is preferred that the corner connector parts themselves are designed in such a way that they are fixed in the right-angled position. For this purpose, the corner connector parts can be designed to form a snap-in or latching connection. For this purpose, a corner connector part has, for example, a resiliently deflectable element which is deflected when the corner connector parts are pivoted and, in the right-angled position, engages in a corresponding latching receptacle on the other corner connector parts.

According to the invention, a first corner connector part of a first frame assembly and a second corner connector part of a second frame assembly are designed to be coordinated with one another such that the first corner connector part can be inserted into the second corner connector part. For this purpose, the second corner connector part has, for example, a receptacle, the inner contour of which is designed such that the first corner connector part can be inserted into the second corner connector part. The corner connector that connects the two profile strips that are arranged at right angles to one another in a corner in the assembled state therefore consists of two components (corner connector parts) that are only plugged into one another during assembly by the end user.

In this context it can be provided that the plug connection is secured between the first corner connector part of the first frame assembly and the second corner connector part of the second frame assembly by a fixation. For this purpose, in particular an external fixing element, such as a screw, pin or cover cap, can be formed. However, it is preferred that the fixation is formed by a snap or latching connection formed on the first corner connector part and the second corner connector part. For this purpose, the first corner connector part or the second corner connector part has a latching element which is deflected elastically (resiliently) when plugged together and, in the mated position, latches into a corresponding latching receptacle on the other corner connector part.

In a preferred embodiment, the kit in this context has exactly four frame assemblies which each have a corner connector part at their two ends, which are designed to produce a plug connection. Each frame assembly has, in particular, an inner profile strip and an outer profile strip, which are already telescopically inserted into one another in the starting position (and thus parallel to one another).

In order to further reduce the number of frame assemblies, it can be provided that the profile strips or a pair of profile strips each are arranged pivotably with respect to one another and at their in the starting position

free ends each have a corner connector part, which are designed to produce a plug connection with the corner connector parts of the other frame assembly. In this case, a pair of profile strips formed from an inner profile strip and an outer profile strip is pivotably connected via a corner connector part to a further profile strip pair formed from an inner profile strip and an outer profile strip, with corner connector parts being formed at the free ends (facing away from the pivotably formed corner connector parts) to form a plug connection are. This kit therefore includes exactly two frame assemblies to form a right-angled frame.

If the preassembled frame assembly comprises a corner connector part inserted into a profile strip, it is preferred that the corner connector part is inserted into the profile strip with an insertion section. In this context, the corner connector part is designed in particular so that the section of the corner connector part protruding beyond the end of the profile strip does not protrude more than a few millimeters beyond the outer contour of the profile strip. A particularly compact arrangement of the frame assemblies is thus possible in the starting position.

The kit is offered in particular in a package in which the frame assemblies are arranged, the profile strips of all frame assemblies being arranged parallel to one another when the kit is arranged in the package.

A frame is also proposed which is assembled from a kit described above. The frame is provided in particular for the formation of an insect protection device, for which purpose an insect protection net / grille (possibly also pleated) comprised by the kit can be attached to the frame. For example, the insect screen may be for a window where the assembled frame has four frame struts (two vertical and two horizontally aligned). The frame can, however, also be designed for an insect protection device for a door, for which purpose the assembled frame has a central strut in addition to the outer frame struts, which is particularly horizontally aligned in the assembled state and connects the side frame struts of the insect protection door with one another, with a central connector with the outer frame struts the middle frame strut connects. In this case, the middle frame strut can be connected to the further frame struts via corresponding corner connector parts. To form the center strut, a center connector can consist of three corner connector parts, which are optionally designed to be pivotable with respect to one another, so that a frame assembly comprising the profile strips of the center strut has three profile strips (two profile strips for the outer frame strut and one profile strip for the middle frame strut). Alternatively, the corner connector parts for forming the center connector can be designed in such a way that three corner connector parts of different frame assemblies, each arranged on a profile strip, can be plugged together.

Figure 1 shows a first kit la with four identical, each preassembled frame assemblies 3.1, 3.2, 3.3 and 3.4. Each frame assembly 3.1 to 3.4 has an outer profile strip 4.1 into which a first corner connector part 5.1 with an insertion section (not visible in the figures) is inserted. The first corner connector part 5.1 is connected to a second corner connector part 5.2 via a pivot axis 6, the second corner connector part 5.2 being inserted into an inner profile strip 4.2 with an insertion section (not visible in the figures). In Figure 1, the frame assemblies 3.1 to 3.4 are shown in their starting position, in which the outer profile strip 4.1 and the inner profile strip 4.2 are arranged parallel to one another and offset from one another. In Figure 2 it is shown how the outer profile strip 4.1 is pivoted to the inner profile strip 4.2 about the pivot axis 6 until the outer profile strip 4.1 and the inner profile strip 4.2 are arranged at a right angle to each other. In this right-angled alignment, a latching connection 7 is formed between the first corner connector part 5.1 and the second corner connector part 5.2, so that accidental pivoting back is prevented.

As can be seen from Figures 3 and 4, the frame assemblies 3.1 to 3.4 of the first kit la can be arranged in their respective swiveled-out position relative to one another so that the inner profile strip 4.2 of the first frame assembly 3.1 can be inserted into the outer profile strip 4.1 of the second frame assembly 3.2. The correspondingly plugged together first frame 2a is shown in FIG. The frame 2a can easily be changed in size due to the telescopic ability of the outer profile strips 4.1 and inner profile strips 4.2.

In Figure 5, a second kit l b is shown, which has four identical, each preassembled frame assemblies 3.1, 3.2, 3.3 and 3.4. Each frame assembly 3.1 to 3.4 comprises an outer profile strip 4.1 and an inner profile strip 4.2 (see also FIG. 7). A first corner connector part 5.3 is inserted into the outer profile strip 4.1, while a second corner connector part 5.4 is inserted into the inner profile strip 4.2. The first corner connector part

5.3 and the second corner connector part 5.4 are matched in their geometrical design so that the first corner connector part 5.3 can be plugged into the second corner connector part 5.4 so that the profile strips 4.1 and 4.2 of the different frame assemblies are arranged at right angles to one another.

In Figure 6 is a corresponding arrangement of the frame assemblies 3.1 to

3.4 of the second kit lb shown. As can be seen in conjunction with Figure 7, the corner connector parts 5.3 and 5.4 plugged together second frame 2b can easily be changed in size due to the telescopic ability of the outer profile strips 4.1 and inner profile strips 4.2.

In Figure 8, a third kit l c is shown for a third frame 2c. The third kit lc comprises two identical, each preassembled frame assemblies 3.1 and 3.2. As can be seen in particular from a synopsis of FIG. 11, each frame assembly 3.1 and 3.2 has a first corner connector 5.3 which is inserted into an inner profile strip 4.4, the inner profile strip 4.4 itself being pushed into a first outer profile strip 4.1. In the first outer profile strip 4.1 is a corner connector part

5.1 inserted, which is pivotably connected to a corner connector part 5.2 via a pivot axis 6. The corner connector part 5.2 is in turn inserted into an inner profile strip 4.2. On the inner profile strip

4.2, in turn, a second outer profile strip 4.3 is pushed into which a second corner connector part 5.4 is inserted.

As can be seen in particular from FIG. 9, the profile strips of the frame assemblies can be pivoted about the pivot axis 6 from the starting position shown in FIG. 8, in which the profile strips are arranged parallel to one another, until the right-angled position shown in FIG. 9 is reached. In this right-angled position, a latching connection 7 is formed between the corner connector part 5.1 and the corner connector part 5.2, so that an unintentional pivoting back is prevented.

After both frame assemblies 3.1 and 3.2 have been pivoted into the right-angled position, they can be aligned with one another, as shown in FIG. From this position, the first corner connector part

5.3 of the second frame assembly 3.2 are inserted into the second corner connector part 5.4 of the first frame assembly 3.1, while the first corner connector part 5.3 of the first frame assembly 3.1 into the second Corner connector part 5.4 of the second frame assembly 3.2 can be inserted. The connection between the first corner connector part 5.3 and the second corner connector part 5.4 is also secured against unintentional loosening by means of a latching connection 7.

Because the outer profile strips 4.1 and 4.3 can be telescoped relative to the inner profile strips 4.2 and 4.4, the size of the third frame 2c shown in FIG. 11 can easily be changed.
