Description

[0001] The present invention relates to a kit for a frame, and in particular to a kit for a frame of an (insect) screen. Typically, an (insect, pollen, and / or sun) screen is attached to such a screen frame, spanning the opening defined by the frame. The screen can then be mounted on a frame (in particular a window or door frame) of a building opening (in particular a window or door).

[0002] EP 3 835 539 A1, for example, discloses a kit for a frame of an insect screen, the kit comprising four frame assemblies, each frame assembly having an inner profile strip and an outer profile strip that are connected to one another via a corner connector comprising a rotation axis. In the delivered state, the inner profile strips and the outer profile strips of the four frame assemblies are each aligned parallel to one another. The end user must unfold the frame assemblies delivered in this way around the rotation axis of the corner connector so that the inner profile strip and the outer profile strip are arranged at a 90° angle to one another. The end user must then align the profile strips of the frame groups with one another and push them together to form the frame, the inner profile strip of one frame assembly being telescopic relative to the outer profile strip of an adjacent frame assembly.This allows the frame to be easily adapted to windows of different sizes. A frame consisting of four frame assemblies is also known from US Pat. No. 4,279,288 A. Although such kits significantly simplify assembly for the end user, the presence of four frame assemblies requires the assembly of a large number of frame assemblies. US Pat. No. 498,868 discloses a preassembled and foldable frame.

[0003] Furthermore, EP 3 835 539 A1 also discloses a kit consisting of exactly two frame assemblies, each of which can be brought into a right-angled position for assembly. However, these frame assemblies feature a plug-in connection at the free ends in the area of ​​the corner connectors. Therefore, different corner connector components are required at the free ends of these frame assemblies than those required to form a pivot joint within a frame assembly. Therefore, providing such a kit with exactly two frame assemblies requires a larger number of different components.

[0004] EP 3 690 177 A1 and EP 3 910 155 A1 each disclose a solution for protecting a hinged corner connector in its unfolded position against accidental folding back. Thus, EP 3 690 177 A1 provides a separate fixing element that can be inserted into both connecting legs of a corner connector in the unfolded assembly position. EP 3 910 155 A1 proposes that the corner connector have a clamping design onto which an attachment device can be clipped. There is also a desire for the frame to be secured even more reliably against folding back. Furthermore, it is desirable for the frame to be highly stable.

[0005] 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 an insect screen door which is even easier for an end user to assemble.

[0006] A solution to the problem is provided by a kit having the features of claim 1. Further solutions and advantageous developments of the kit are specified in the dependent claims and in the preceding and following description, wherein individual features of the description and the dependent claims can be combined with one another in a technically expedient manner.

[0007] The problem is solved in particular by a kit for a frame, and in particular by a kit for a frame of an insect screen, and preferably for a frame of an insect screen door. The kit comprises a first pre-assembled frame assembly and a second pre-assembled frame assembly. Furthermore, the kit comprises at least one first connecting profile strip and at least one second connecting profile strip.

[0008] Each of the two frame assemblies comprises a first free profile strip, a second free profile strip, and a connecting device which has at least one further profile strip. The first free profile strip is connected to the connecting device at a first end of the connecting device via a first pivot joint having a pivot axis. The second free profile strip is connected to the connecting device at a second end of the connecting device via a second pivot joint having a pivot axis. The two pivot joints of each frame assembly are designed such that, in an initial position, the two free profile strips and the connecting device are aligned parallel to one another, and that the free profile strips can be moved into an assembly position by pivoting relative to the connecting device about the respective pivot axis, in which the frame assembly is U-shaped.

[0009] In the assembled position, in which the two frame assemblies are U-shaped, the first free profile strip of the first frame assembly, on the one hand, and the first free profile strip of the second frame assembly, on the other hand, can be telescopically connected to the at least one first connecting profile strip. Furthermore, the second free profile strip of the first frame assembly, on the one hand, and the second free profile strip of the second frame assembly, on the other hand, can be telescopically connected to the at least one second connecting profile strip. The frame, which can be assembled in this way, is thus delimited on its outer circumference by the elements (free profile strips and connecting device) of the frame assemblies and by the connecting profile strips.

[0010] In other words: The basic idea of ​​the invention is that the end user is provided with two modules with the pre-assembled frame assemblies, which the end user can bring into a U-shaped position by unfolding the free profile strips, wherein the two U-shaped unfolded modules are connected to one another by the connecting profile strips, for which purpose the first free profile strips of the frame assemblies are inserted in a telescopic manner into or onto the at least one first connecting profile strip, while the second free profile strips of the frame assemblies are inserted in a telescopic manner into or onto the at least one second connecting profile strip. It is thus possible for the frame to have a greater height than the sum of the corresponding free profile strips of different frame assemblies, wherein the height can also be adapted to a building opening due to the telescopic nature.

[0011] The essentially parallel alignment of the free profile strip in the initial position to the connecting device also ensures that the kit can be provided to the end customer in a compact form in a container (packaging). While the free profile strips in the assembly position are essentially arranged in a plane defined jointly with the connecting device, it is entirely possible that in the initial position the free profile strips are offset orthogonally to the plane and arranged directly next to each other, which is still considered parallel.

[0012] The at least one first connecting profile strip and the at least one second connecting profile strip can each comprise at least one inner profile strip and at least one outer profile strip, so that the at least one first inner profile strip and the at least one first outer profile strip can be arranged telescopically relative to one another. This allows for an even greater frame height, if necessary, while the connecting profile strips have a comparatively short length in the state provided to the end customer.

[0013] However, it is preferred that the kit has exactly one first connecting profile strip and exactly one second connecting profile strip, wherein in the assembled position both the first free profile strip of the first frame assembly and the first free profile strip of the second frame assembly can be telescopically inserted into or onto the first connecting profile strip from opposite sides, wherein the second free profile strip of the first frame assembly and the second free profile strip of the second frame assembly can be inserted into or onto the second connecting profile strip from opposite sides. The number of components provided to the end customer is therefore low, which also reduces the assembly effort. In this context, it is particularly preferred if the free profile strips of the frame assemblies are designed as inner profile strips and the connecting profile strips as outer profile strips.This configuration makes it easier for the end customer to attach additional components to the connecting profile strips of the frame produced by the kit.

[0014] If the frame can have a greater height due to the provision of connecting profile strips, it is desirable in some applications to give the frame additional stability. For this purpose, it is proposed that the kit can comprise a central connecting device with which two connecting profile strips arranged parallel to one another in the assembled state can be connected. Such a central connecting device can be implemented, for example, by at least one profile strip that is attached on the one hand to a connecting profile strip of the at least one first connecting profile strip and on the other hand to a profile strip of the at least one second connecting profile strip. For example, the central connecting device can be screwed to the two connecting profile strips.However, it is also possible that the central connecting device is attached to the connecting profile strips by other positive and / or non-positive connections.

[0015] If the frame is adjustable in width, the central connecting device can comprise at least one inner profile strip and at least one outer profile strip, which can be telescopically moved into one another. By telescopically moving them relative to one another, the length of the central connecting device and thus the width of the frame can be adjusted. Preferably, the central connecting device comprises exactly two inner profile strips, each of which can be attached to a connecting profile strip, and exactly one outer profile strip, into which the two inner profile strips can be inserted from opposite sides.

[0016] In principle, it would be conceivable for at least one axis of rotation of the pivot joint to be aligned in the plane spanned by the frame and approximately at a 45° angle to the direction of extension of the free profile strip. However, it is preferred that the axes of rotation of the pivot joints of both frame assemblies are aligned parallel to one another (when the frame is assembled) and orthogonal to a plane spanned by the frame. In this embodiment, the free profile strips are arranged in the plane defined by the free profile strips and the connecting device in the assembly position, even during transfer from the starting position to the assembly position. In the latter embodiment, a particularly stable connection of the free profile strips to the connecting device in the assembly position is possible.

[0017] In a preferred embodiment, the (free) profile strips are designed as inner profile strips or as outer profile strips. For example, it would be possible for all free profile strips of the frame assemblies to be designed as inner profile strips that can be inserted into outer profile strips of the connecting profile strips. However, it can also be provided that the two frame assemblies have outer profile strips as free profile strips that can be pushed onto inner profile strips of the connecting profile strips.

[0018] In the simplest case, the (mutually assigned) profile strips can be designed as nestable tubes (with a circular or rectangular cross-section). However, it is preferred that the profile strips have at least one contour extending along their longitudinal extent, which, for example, enables the attachment of a seal and / or a protective grille. In particular, a groove extending in the direction of the longitudinal extent of the profile strip can be provided for receiving a (brush) seal. Alternatively or additionally, a contour projection or contour recess can be provided, which extends along the longitudinal extent of the profile strip, to which an (insect) protective grille can be secured, if necessary by means of additional components (such as a fixing strip).

[0019] The outer contour of an inner profile strip is matched to the inner contour of the associated outer profile strip so that they can be telescopically pushed into one another.

[0020] Preferably, the free profile strips of the frame assembly are arranged substantially parallel but offset from one another and from the connecting device in the initial position. Thus, the free profile strips of a frame assembly can be offset from one another orthogonally to the plane and arranged on the same side of the connecting device. Although the free profile strips are arranged in one plane in the assembly position, they can be arranged directly next to one another (orthogonal to the plane) in the initial position by means of slight bracing.

[0021] In principle, it is possible for the connecting device to be fixed in length. In this case, the frame could only be adjustable in size (height) along the longitudinal extension of the connecting profile strip. However, it is preferred that the connecting device of a frame assembly comprises at least one inner profile strip and at least one outer profile strip arranged telescopically relative to the at least one inner profile strip. Thus, the frame is adjustable in size in its plane in two mutually orthogonal directions.

[0022] In principle, it is possible for the swivel joint having the rotation axis to be formed integrally with a profile strip. However, it is preferred for the swivel joint to be formed by an independent component, namely a profile connector. In this case, the first free profile strip and the second free profile strip are each connected to the connecting device via a profile connector forming the swivel joint. In this context, it can be provided that a first connecting leg of a profile connector is inserted into a free profile strip and a second connecting leg of the profile connector, which can be pivoted about the rotation axis relative to the first connecting leg, is inserted into a profile strip of the connecting device. The design of specific profile connectors, which are also provided as corner connectors for connecting exactly two profile strips, is described further below.

[0023] It can also be provided that the two frame assemblies are each secured in their assembled position by a fixing device. For example, the frame assemblies can have locking mechanisms in the area of ​​the swivel joint that interlock in the assembled position, thus preventing accidental pivoting back. Alternatively or additionally, the fixing can be implemented by a separate fixing element that secures the swivel joint in its unfolded position against unintentional pivoting back.

[0024] Since the present invention is aimed at providing a compact kit while simultaneously simplifying assembly, the kit is proposed to include a package (e.g., a box) in which the two frame assemblies are arranged in their initial position and the connecting profile strips. Of course, other components of the kit, such as fixing elements, suspension elements, the central connecting device, and / or insect screens, can be arranged in the package.

[0025] A profile connector for a frame and in particular for a frame assembly of the previously described kit is also described. The profile connector comprises at least one first connecting leg, which can be inserted into a profile strip, and a second connecting leg, which can be inserted into a profile strip. The profile connector also comprises a pivot joint having at least one pivot axis between the first connecting leg and the second connecting leg, which pivot joint is designed such that the first connecting leg and the second connecting leg consist of a

[0026] The starting position can be transferred by a relative pivoting movement about the at least one axis of rotation into an assembly position in which the first connecting leg and the second connecting leg are arranged in a plane at a right angle to one another.

[0027] It is now further proposed that the profile connector comprise a screw and that the first connecting leg has a receptacle (for example a simple hole or a threaded bore) for the screw, wherein the receptacle is arranged such that the screw can be screwed through the second connecting leg into the receptacle in the assembled position. For this purpose, the second connecting leg has a type of hole through which the screw projects and against the edge of which the screw head comes to rest. The screw can thus be used to clamp the first connecting leg to the second connecting leg, so that due to the relative pivoting mobility, any play existing between the connecting legs can be minimized or completely eliminated even in the assembled position, which in turn gives the frame greater stability.

[0028] If the profile connectors are made of plastic, it is sufficient for the screw receptacle to be designed as a simple hole into which the screw can be screwed. However, if the connecting legs are made of metal, it would be advisable to design the receptacle as a threaded hole.

[0029] The profile connector comprises, in particular, a connecting leg that can be at least partially inserted into a previously described profile strip, in particular with a force fit. The outer profile of the section of the connecting leg that can be inserted into the profile strip is thus adapted to the inner profile of the corresponding profile strip.

[0030] In particular, in the part protruding beyond the profile strip, the profile connector has at least one axis of rotation for forming the pivot joint. If the movement of the connecting legs from the initial position to the assembly position occurs in the plane defined by the assembly position, preferably exactly one axis of rotation is formed.

[0031] If the profile connector has exactly two connecting legs that can be brought into a right angle to each other, it is also referred to as a corner connector. However, it can also be provided that the profile connector has three connecting legs, in which case each connecting leg is arranged at a right angle to at least one other connecting leg in the assembled position. Such a profile connector can be used, for example, to form a frame for an insect screen door. In this case, a receptacle for a screw can be formed in each of the two connecting legs, whereby the screw can be screwed through the other (third) connecting leg into the receptacle.

[0032] The swivel joint and the connecting legs are designed in particular such that the connecting legs are arranged parallel to each other in the starting position.

[0033] The invention and the technical environment are explained below using the figures as examples. They show schematically Figure 1: a kit for a frame of an insect screen, Figure 2: the frame during assembly, Figure 3: the assembled frame, Figure 4: a profile connector and Figure 5: a sectional view through the profile connector.

[0034] The one in the Figure 1 The kit 3 shown for a frame comprises a first frame assembly 1, a second frame assembly 2, a first connecting profile strip 7.1, a second connecting profile strip 7.2 and a central connecting device 10.

[0035] The first frame assembly 1 comprises a first free profile strip 1.1, a second free profile strip 1.2 and a connecting device 1.3 formed from two profile strips 1.3a and 1.3b (see in particular also Figure 2 and 3 ).

[0036] The second frame assembly 2 comprises a first free profile strip 2.1, a second free profile strip 2.2 and a connecting device 2.3 formed from two profile strips 2.3a and 2.3b (see also Figure 2 and 3 ). The free profile strips 1.1, 1.2, 2.1 and 2.2 of the frame assemblies 1 and 2 are each connected via a profile connector 5 to the associated connecting device 1.3 or 2.3. Such a profile connector is described with reference to the Figures 4 and 5 explained below.

[0037] The first free profile strips 1.1 and 2.1 are each connected to the connecting device 1.3, 2.3 via a first pivot joint 4.1 having a pivot axis 4.1a (see also Figure 4 with respect to the rotation axis 4.1a). The second free profile strips 1.2 and 2.2 are each connected to the connecting device 1.3, 2.3 via a second pivot joint 4.2 having a rotation axis 4.2a.

[0038] In the Figure 1The frame assemblies 1 and 2 are shown in their respective starting positions. In this starting position, the free profile strips 1.1, 1.2, and 2.1 and 2.2 are aligned parallel to the respective connecting devices 1.3, 2.3 and to each other.

[0039] The first connecting profile strip 7.1 and the second connecting profile strip 7.2 are each designed as an external profile strip.

[0040] The central connecting device 10 comprises two outer profile strips 10.1 and 10.2 and an inner profile strip 10.3, which can be telescopically inserted into the two outer profile strips 10.1 and 10.2.

[0041] In the Figure 1 In the initial state shown, the individual assemblies and components of the kit can be easily stored in packaging and made available to an end customer.

[0042] In the Figure 2 is kit 3 of the Figure 1shown, wherein the frame assembly 1 is in an assembly position and the frame assembly 2 is in an intermediate position between the initial position and the assembly position.

[0043] The free profile strips 2.1 and 2.2 of the second frame assembly 2 are thus already pivoted by a few degrees from their initial position. In the assembly position, as shown with reference to the frame assembly 1, the free profile strips 1.1 and 1.2 are each arranged at a right angle to the connecting device 1.3. Figure 2 It is also clear that the connecting device 1.3 consists of two profile strips 1.3a and 1.3b, which can be telescoped towards each other to adjust the width of the subsequent frame.

[0044] In the Figure 3In the state of the frame shown, the first free profile strip 1.1 of the first frame assembly 1 and the first free profile strip 2.1 of the second frame assembly 2 are inserted from opposite sides into the first connecting profile strip 7.1, while the second free profile strip 1.2 of the first frame assembly 1 and the second free profile strip 2.2 of the second frame assembly 2 are inserted from opposite sides into the second connecting profile strip 7.2. The height of the frame can thus be adjusted by moving the frame assemblies 1 and 2 along the longitudinal extent of the connecting profile strips 7.1 and 7.2. In addition, the two connecting profile strips 7.1 and 7.2 are connected to one another via the central connecting device 10, so that the frame has a high level of stability.

[0045] In the Figures 4 and 5 A profile connector 5 designed as a corner connector is shown, which is also used in the frame assemblies of the Figures 1 to 3can be used. The profile connector 5 has a first connecting leg 5.1 and a second connecting leg 5.2, each of which can be inserted in sections into a profile strip. A pivot axis 4.1a is formed between the first connecting leg 5.1 and the second connecting leg 5.2, so that the connecting legs 5.1, 5.2 can be pivoted from an initial position, in which the connecting legs 5.1, 5.2 or the profile strips are aligned approximately parallel to one another, into an assembly position in which the connecting legs 5.1, 5.2 or the profile strips are arranged at a right angle to one another. Figure 4 the connecting legs 5.1 and 5.2 are in the assembly position.

[0046] As can be seen particularly from the sectional view of the Figure 5As can be seen, a receptacle 8 is formed in the first connecting leg 5.1, while a through hole 9 is formed in the second connecting leg 5.2.

[0047] The mount 8 and the through-hole 9 are designed on the connecting legs 5.1 and 5.2 so that a screw 6 can be screwed through the through-hole 9 into the mount 8 when the profile connector is in the assembled position. The screw 6 clamps the first connecting leg 5.1 against the second connecting leg 5.2 and thus holds it in the assembled position. The screw 6 also eliminates any play between the connecting legs 5.1 and 5.2, further increasing the stability of the frame. List of reference symbols
