Description

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, insect protection window or light well cover. To form an insect protection device, an insect protection net or grid 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 the 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 them to the window/door size. This makes it easier to adjust the length of the frame struts to the window/door size can be adjusted, it is also known to form the frame struts from at least one inner profile bar and at least one outer profile bar, which are mutually telescopic.

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 must plug into a profile strip. In this case, there is only a 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 little stability. In addition, after assembly, a corner area of the corner connector is visible between the plug-in sections.

In order to provide a more aesthetically pleasing and also more stable frame, proposes DE 10 2015 116 588 B4 proposes to pre-assemble the inner and outer profile strips in pairs using a corner connector and to provide the pre-assembled pairs of profile strips as a kit. Since the corner connectors are also secured with the profile strips by a form fit in the direction of insertion, there is greater stability. In addition, the profile strips have a miter cut at the end of the corner connector, so that the profile strips of a pair of profile strips lie against one another with their miter cuts. However, the packaging of such a kit has a comparatively large volume due to the right-angled arrangement of the pre-assembled pairs of profile strips.

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

Out of U.S. 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 frame consists of three frame assemblies with a hinge and two separately mountable moldings. Out of DE 10 2015 117 643 A1 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 specify a kit for a frame which can be assembled more easily by the end user and whose packaging has the smallest possible volume.

The object is achieved by a kit with the features of the respective independent claims 1 and 5. Advantageous developments of the kit are given in the dependent claims and in the description, with individual features of the advantageous developments being able to be combined with one another in a technically sensible 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 having 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 a corner connector part arranged on each profile strip, wherein the profile strips and the corner connector parts of the frame assembly are designed in such a way that the profile strips of all frame assemblies are arranged or can be arranged parallel to one another in a starting position and the frame assemblies can be plugged together to form a rectangular frame, in which two profile strips each are arranged telescopically to one another.

In its basic idea, the invention therefore provides that the kit comprises in particular an even number of (pre-assembled) frame assemblies, with each frame assembly in particular having exactly 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 slats) or exactly four inner and/or outer slats (namely: each frame assembly has two inner slats and two outer slats). On each profile bar A corner connector part is also arranged in the frame assembly, for which purpose the corner connector part is either designed in one piece with the profile strip or is preferably non-positively and/or positively connected as a preassembled part to the profile strip.

Provision is therefore made for the corner connector, which connects the profile strips arranged at right angles to one another in the final assembled state, to consist of at least two parts (corner connector parts). As also explained below, the two corner connector parts are designed in such a way that they can be plugged into one another or are connected to one another so that they can pivot relative to one another, forming a type of hinge.

The profile strips of all frame assemblies can therefore initially be arranged parallel (aligned or offset) to one another, so that the pre-assembled frame assemblies can be arranged in a package to save space.

For the (final) assembly of the frame, the frame assemblies are plugged together, with the corner connector parts of different frame assemblies being plugged into one another or inner profile strips and outer profile strips of different frame assemblies being telescopically aligned with one another, with an inner profile strip of a first frame assembly being telescopically inserted/slide into the outer profile strip of a second frame assembly. In the second case, it is also necessary for the profile strips of a frame assembly, which are connected via two corner connector parts arranged pivotably relative to one another, to first be pivoted into a right angle.

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 different frame assemblies can be telescopically connected to one another during assembly.

After the kit has been put together to form a frame, the size of the frame can be easily changed by sliding the inner and outer profile strips of the frame struts telescopically towards one another. If the frame has the desired size, it can be fixed in size with suitable means (screws, insect screens, fixing strips).

The assembly kit according to the invention for a frame therefore has not only 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, which are arranged pivotably to one another, so that the two profile strips of the frame assembly are arranged parallel (aligned or offset) to one another in the initial 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, about 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 initial 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.

According to a further aspect of the invention, the kit has exactly four frame assemblies, the two profile strips of which can be pivoted relative to one another, the profile strips being designed as an inner profile strip and/or outer profile strip and with the inner profile strip of a first frame assembly in the right-angled position the outer profile strip of a second frame assembly can be inserted. The inner profile strip and the outer profile strip are matched to one another in terms of their outer contour or inner contour in such a way that they can be inserted into one another and telescopically moved/displaced relative to one another.

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

The two profile strips are preferably secured in the right-angled position by a fixation. In particular, this fixation acts on the corner connector parts of the frame assemblies, which are designed to be pivotable relative to one another. The corner connector parts can be fixed in their mutually perpendicular position, 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 or snap-in connection. For this purpose, a corner connector part has, for example, a resiliently deflectable element that is deflected when the corner connector parts are pivoted and, in the right-angled position, engages in a corresponding snap-in receptacle on the other corner connector part.

According to one aspect of 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 match one another in such a way that the first corner connector part can be inserted into the second corner connector part. Points to this the second corner connector part, for example, has a receptacle whose inner contour is designed in such a way that the first corner connector part can be inserted into the second corner connector part. The corner connector, which connects the two profile strips arranged at right angles to one another in a corner when assembled, 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-in connection between the first corner connector part of the first frame assembly and the second corner connector part of the second frame assembly is secured by a fixation. In particular, an external fixing element such as a screw, pin or cover cap can be designed for this purpose. 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 elastically (resiliently) deflected when mated and latches into a corresponding latching receptacle on the other corner connector part in the mated position.

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

In order to further reduce the number of frame assemblies, provision can be made for the profile strips or a pair of profile strips to be arranged pivotably relative to one another and at their 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 another pair of profile strips formed from an inner profile strip and an outer profile strip, with corner connector parts being formed on the free ends (facing away from the pivotably designed corner connector parts) to form a plug connection are. This kit therefore includes exactly two frame assemblies to form a rectangular frame.

If the preassembled frame assembly comprises a corner connector part inserted into a profile strip, one aspect of the invention provides 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 in such a way that the section of the corner connector part that protrudes 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 in the starting position is thus possible.

In particular, the kit is presented in a package in which the frame assemblies are placed, with the moldings of all the frame assemblies being parallel to each other when the kit is placed in the package.

A frame is also proposed which is assembled from a kit described above. The frame is intended in particular for forming an insect protection device, for which purpose an insect protection net/grid (possibly also pleated) that is included in the kit can be attached to the frame. For example, the insect screen may be provided for a window where the assembled frame has four frame braces (two vertical and two vertical). aligned horizontally). However, the frame can also be designed for an insect protection device for a door, for which purpose the assembled frame has, in addition to the outer frame struts, a center strut which, in the assembled state, is aligned in particular horizontally and connects the side frame struts of the insect protection door to one another, with a center connector connecting the outer frame struts with the center frame brace. In this case, the middle frame strut can be connected to the other frame struts via corresponding corner connector parts. To form the center strut, a center connector can consist of three corner connector parts that can be pivoted to one another, so that a frame assembly that has 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 central 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 1a with four identical, each pre-assembled 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 is inserted with an insertion section (not visible in the figures). The first corner connector part 5.1 is connected via a pivot axis 6 to a second corner connector part 5.2, the second corner connector part 5.2 being inserted with an insertion section (not visible in the figures) into an inner profile strip 4.2. 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 is shown how the outer profile bar 4.1 is pivoted to the inner profile bar 4.2 about the pivot axis 6 until the outer profile bar 4.1 and the inner profile bar 4.2 are arranged at a right angle to one another. In this right-angled orientation, a locking 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.

How from the Figures 3 and 4 shows, the frame assemblies 3.1 to 3.4 of the first kit la can be arranged in their respective pivoted position to each other that the inner profile bar 4.2 of the first frame assembly 3.1 can be inserted into the outer profile bar 4.1 of the second frame assembly 3.2. The correspondingly assembled first frame 2a is in figure 4 shown. The size of the frame 2a can be easily changed due to the telescoping ability of the outer profile strips 4.1 and inner profile strips 4.2.

In figure 5 a second kit 1b is shown, which has four identical, each pre-assembled frame assemblies 3.1, 3.2, 3.3 and 3.4. Each frame assembly 3.1 to 3.4 includes an outer profile bar 4.1 and an inner profile bar 4.2 (see also figure 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 coordinated in their geometric design so that the first corner connector part 5.3 can be inserted 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 a corresponding arrangement of the frame assemblies 3.1 to 3.4 of the second kit 1b is shown. As in synopsis with figure 7 can be seen, the over the corner connector parts 5.3 and 5.4 assembled second frame 2b easily changed in size due to the telescoping of the outer profile strips 4.1 and inner profile strips 4.2.

In figure 8 a third kit 1c is shown for a third frame 2c. The third kit 1c includes two identical, each pre-assembled frame assemblies 3.1 and 3.2. How in particular from together with figure 11 shows, each frame assembly 3.1 and 3.2 has a first corner connector 5.3, which is inserted into an inner profile bar 4.4, the inner profile bar 4.4 itself being pushed into a first outer profile bar 4.1. A corner connector part 5.1 is inserted into the first outer profile strip 4.1 and is pivotably connected via a pivot axis 6 to a corner connector part 5.2. The corner connector part 5.2 is in turn inserted into an inner profile strip 4.2. A second outer profile strip 4.3 is in turn pushed onto the inner profile strip 4.2, into which in turn a second corner connector part 5.4 is inserted.

Like in particular figure 9 shows, the moldings of the frame assemblies can be taken from the in figure 8 shown initial position, in which the profile strips are arranged parallel to one another, are pivoted about the pivot axis 6 until the figure 9 shown perpendicular position is reached. In this right-angled position, a locking connection 7 is formed between the corner connector part 5.1 and the corner connector part 5.2, so that 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 is shown in figure 10 is shown. From this position, the first corner connector part 5.3 of the second frame assembly 3.2 can be 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 secured against unintentional loosening by means of a locking connection 7 .

Due to the telescoping ability of the outer profile strips 4.1 and 4.3 to the inner profile strips 4.2 and 4.4, the in figure 11 illustrated third frame 2c can be easily changed in size.
