Description

The present invention relates to an insect protection device for insertion into a building opening, for example in a door frame or window frame, comprising a clamping frame, the interconnected via horizontal and vertical frame struts each have at least one outer profile strip and a telescopically inserted into the outer profile strip (s) inner profile strip , And a fixed by means of terminal strips on the tenter mesh.

An insect protection device with the aforementioned features is made EP 2 878 757 A2 known. By forming the frame struts with at least one telescoping in at least one outer profile strip inner profile strip, it is possible to adjust the size of the clamping frame prior to insertion into the building opening to the size of the building opening, so that a kit of insect protection device for different sized building openings can be used. The further the inner profile strip is inserted into the at least one outer profile strip, whereby the insertion depth increases, the smaller the overall length of the corresponding frame strut. It is desirable that the clamping frame can be assembled with as little tool and in a few assembly steps with the desired size for the corresponding building opening.

In order to fix the inner profile strip in a desired insertion depth in the outer profile strip and so to set a total length of the respective frame strut is according to EP 2 878 757 A2 Screw a tapping screw with an Allen key into the outer profile strip. To set the network on a frame strut, two as Kederleiste or cover strip designated terminal strips are also required, one of which is clamped in the secondary profile of the outer profile and the other in the secondary profile of the inner profile, whereby the network is set in the secondary profile strips. At each frame strut so at least two terminal strips must be attached to the determination of the network of this frame strut.

The object of the present invention is therefore to at least partially solve the problems described with reference to the prior art and, in particular, to simplify assembly by avoiding tools and by reducing the components or assembly steps.

This object is achieved by an insect protection device having the features of the independent claim. Advantageous developments of the insect protection device are specified in the dependent claims and in the description, wherein features of advantageous developments in a technologically meaningful manner are combined with each other.

The problem is solved in particular by an insect protection device with the features mentioned, in which the at least one outer profile strip of a frame strut forms along its longitudinal extent, forming on the inside a guide channel and outside having a cross-sectional shape having main projection and in which the associated inner profile strip along its Forming a longitudinal extension extending auxiliary projection which engages in the guide channel of the main projection of the outer profile strip, wherein an adapter profile strip with one of the outer cross-sectional shape of the main projection at least partially corresponding cross-sectional contour is plugged for mounting the insect protection device on a protruding from the guide channel of the main projection portion of the auxiliary projection, wherein by a Length of the adapter profile bar the insertion depth of the inner profile strip is limited in the outer profile strip and thereby an overall length of this frame strut is fixed in the mounted state and wherein the network of this frame strut defining terminal strip extends integrally over the entire length of the frame strut and for fixing the network in a portion of the main projection of the outer profile strip and in another portion of the auxiliary projection the inner profile strip plugged adapter profile strip overlaps.

The invention thus provides in its basic idea that the plugged onto the auxiliary projection adapter profile takes two functions. On the one hand is achieved by the adapter profile strip that with the main projection on the outer profile strip and plugged onto the auxiliary projection adapter profile strip a fastening device is formed with a uniform along the entire frame strut cross-sectional shape at which a one-piece terminal strip determines the network on the one frame strut. On the other hand, the adapter profile strip ensures that in an assembled state in which in particular the frame struts are connected to each other via corner joints, the respective frame strut can not be further reduced than the predetermined by the length of the adapter profile strip minimum overall length. When pushing together the assembled clamping frame comes namely, for example, the adapter profile strip on the one hand with its one end face on the corner connector to plant and on the other hand with its other end face on an end face of the outer profile strip. It is thus achieved that the net on each frame strut with only one terminal strip can be fixed, with no additional tool is required for the specification of a minimum total length of the mounted clamping frame.

The clamping frame consists in particular of two lateral vertical frame struts and an upper and a lower horizontal frame strut, which are interconnected via corner connectors. It can also be provided that in the clamping frame further, reinforcement forming frame struts are arranged, which extend from the upper to the lower frame strut or from the left to the right frame strut. At least two opposite frame struts each have at least one outer profile strip and an inner profile strip which can be telescoped to the outer profile strip. However, the frame struts can also each have two outer profile strips and a telescopic inner profile strip in both outer profile strips. The inner profile strip is inserted in each case over a designated insertion depth in the outer profile strip. For the telescoping, the inner contour of the outer profile strip is in particular complementary to the outer contour of the inner profile strip.

The inner profile strip has a particular solid auxiliary projection which extends along the entire length of the inner profile strip. The projection protrudes laterally to the longitudinal extent of the inner profile strip. A width of the auxiliary projection transversely to the longitudinal extent of the inner profiled strip is greater in particular at its outer end than at its base. The width of the auxiliary projection thus increases transversely to the length of the inner profile strip steadily or suddenly.

The outer profile strip has a main projection extending along the length of the outer profile strip, which is hollow on the inside and thus forms a guide channel in which the auxiliary projection engages. In particular, a width of the guide channel is lower at its base than at its outside end. With appropriate design of the auxiliary projection of the inner profile strip as an optimal power transmission from outer profile bar is achieved on the inner profile strip. The main projection has an outer cross-sectional shape in cross-section, which is constant along the outer profile strip.

The adapter profile strip in turn has an outer cross-sectional contour in cross-section, which is adapted over at least one (circumferential) portion of the cross-sectional shape of the main projection. For example, if the main projection at its outer end has a C-shaped outer cross-sectional shape, the outer cross-sectional contour of the adapter profile strip in particular C-shaped or Ω-shaped. On the inside, the cross-sectional contour of the adapter profile strip is adapted in particular to the outer cross-sectional shape of the auxiliary projection. By the adapter profile strip thus the area of the frame strut in cross-section along the longitudinal extent is constant in the assembled state, to which the terminal block is clamped to fix the network. The network is thus defined between the terminal block and the main projection in the region of the outer profile strip and between the terminal block and the adapter profile strip in the remaining area of the frame strut. When forming the adapter profile strip with a Ω-shape is also an end face of the adapter profile strip with an end face of the outer profile strip so in Appendix that a formed on the end face of the outer profile edge cutting edge of the outer profile bar is not accessible.

For mounting the insect protection device, in particular, first the inner profile strip and the outer profile strip of each frame strut are inserted into one another and connected to one another by means of corner connectors. In the following, the still variable in size clamping frame can be held to the building opening, with the lengths of the adapter profile strips is to be determined. Namely, the length of an adapter profile strip corresponds exactly to the length of the section of the inner profile strip between corner connector and outer profile strip, which is not inserted into the outer profile strip. In the following, therefore, the adapter profile strips can be shortened to the desired lengths and attached to the auxiliary projections of the respective inner profile strips, for which purpose the clamping frame can be aligned horizontally. The clamping frame is then pushed together so far that the end faces of the adapter profile strips are in each case on the one hand with an end face of the outer profile strip and on the other hand with a corner connector or an end face of another outer profile strip in abutment. In this condition, the size of the tenter should correspond to the size of the building opening. The clamping frame can not be pushed together, since the minimum total length of each frame strut is determined by the length of the respective adapter profile strip. The adapter profile strips of opposite frame struts are thus usually the same length.

In the following, the terminal strip can then be shortened to the length of the total length of the respective frame strut. The network formed via the clamping frame is then fixed in its position by attaching the terminal strips on the respective frame struts, wherein the terminal block is clamped in a partial area on the outer profile strip and in another portion of the adapter profile strip with the same outer profile. In the following, the edge of the net projecting beyond the clamping frame can still be cut off. Thus, the Insect protection device can be mounted without the use of tools. Even the use of a cutting tool to shorten the adapter profile strip and the terminal strip may be unnecessary if the terminal strips or the adapter profile strips are made of a material that can be canceled relatively accurately at a desired location.

It can be provided that a handle is attached to at least one frame strut, which is fixed with a foot-side portion of the terminal block to the auxiliary projection of the inner profile strip and which is in contact with an end face on the auxiliary projection of the inner profile strip adapter profile strip. In particular, the handle with its opposite end face in contact with the outer profile strip. Since thus the handle is also fixed by means of the terminal strip on the frame strut, no tool for mounting the handle is required. When using the handle whose length is considered in the longitudinal extent of the frame strut in the design of the length of the adapter profile strip. The handle replaced namely in this case over its length the function of the length of the foot-side portion of the handle shorter adapter profile strip.

In one embodiment, it is provided that on the outer profile strip in addition to the main projection extending along its longitudinal main guide is formed, which has laterally projecting end webs in the Außenprofilleisteninnere, being formed on the inner profile strip next to the auxiliary projection to the end webs complementary groove channels in the in the outer profile strip inserted portion of the inner profile strip record the end webs. The main guide conveys the essential stability between the outer profile strip and the inner profile strip. By projecting laterally is meant in particular that the end webs are aligned on the one hand orthogonal to the longitudinal extent and on the other in the direction of the lateral walls of the outer profile strip. Thus, on the one hand, the projection of the outer profile strip protrudes outward and on the other hand protrude the end webs into the interior of the outer profile strip, a particularly play-free telescopic connection of the outer profile strip and inner profile strip is given in the combination.

It is particularly envisaged that the terminal block is integrally formed of two different plastics, of which the harder plastic forming the main projection and the adapter profile cross override part of the terminal block and of which the softer plastic laterally projecting from the overlap part, arranged between the frame strut and the building opening Seal member of the terminal block for sealing the tenter frame opposite the building opening forms. To adapt the length of the adapter profile strip, for example, the sealing part can then be torn at the desired location and from there, the complete terminal strip can be shortened. By the hard plastic thus a firm connection with the frame strut and given by the soft plastic a good seal.

The frame struts are in particular connected to one another via corner connectors which can be inserted into the inner profile strips and / or outer profile strips.

In particular, the inner and outer profile strips have an outer wall which is flat toward the outside of the building opening and form the main projection or the auxiliary projection on their sides which are opposite the flat outer walls.

1 shows an insect repellent device 1 with frame struts 3 , each consisting of an outer profile strip 4 and an interior profiled strip 5 consist. The one revolving clamping frame 2 forming frame struts 3 are over in the outer profile strip 4 or inner profile strip 5 inserted corner connectors 25 connected with each other.

The interior profile strips 5 are each telescopic in the outer profile strips 4 with a insertion depth 6 inserted. Opposite frame struts 3 each have an equal overall length 16 on.

For telescopic connection have the outer profile strips 4 one main tour each 20 and a main lead 11 which will be discussed in detail with reference to the other figures. The interior profile strips 5 each have a corresponding main guide 20 and an auxiliary projection 12 on, on the one a length 15 having adapter profile strip 13 is attached, which is also described with reference to the other figures.

A net 8th the insect repellent device 1 is by means of a terminal strip 7 per frame strut 3 on the clamping frame 2 established. The terminal block 7 overlaps in the field of exterior profiles 4 each the main lead 11 and in the field of interior profiling 5 the on the auxiliary projection 12 plugged adapter profile strip 13 ,

In 2 is a view of the outer profile strip 4 shown. The outer profile strip 4 is a hollow bar with a main guide 20 on the left. The main tour 20 has flange-like side walls, which lead into the strip inside and at the ends in the longitudinal direction of the outer profile strip 4 extending end webs 21 are formed. The end webs 21 run in the plane shown parallel to the outer wall 26 , On the right side of the outer profile strip 4 is a major lead 11 formed, in its interior a guide channel 9 has and on its outer side an outer oval cross-sectional shape 10 ,

In 3 is the inner profile strip 5 shown. The inner profile strip 5 also has a flat outer wall 26 on. On the left is a main tour 20 formed in the longitudinal extent of the inner profile strip 5 running groove channels 22 formed. On the in 3 right side has the inner profile strip 5 a massive auxiliary projection 12 on that one width 17 has at its base less than at its outer end with an oval head.

The inner profile strip 5 is shaped so that it telescopes into the outer profile strip 4 can be inserted. The end webs 21 in the outer profile groove inside therefore correspond to the groove channels 22 on the inner profile strip 5 , In addition, the inner cross section of the guide channel corresponds 9 with the outer contour of the auxiliary projection 12 , On the one hand, the auxiliary projection 12 the inner profile strip 5 in the guide channel 9 the outer profile strip 4 engages and on the other hand, the end webs 21 the outer profile strip 4 in the groove channels 22 the inner profile strip 5 engage, is given a particularly stable telescopic connection due to this double positive engagement with a mutual engagement of a projection in a groove.

In 4 is the adapter profile bar 13 shown in a view. The adapter profile bar 13 has an outer oval cross-sectional contour 14 on, the oval cross-sectional shape 10 of the main projection 11 the outer profile strip 4 equivalent.

In 5 is a view of the terminal block 7 shown. The terminal block 7 comprises an overlapping part formed from a relatively hard plastic 23 and a sealing member formed of a softer plastic 24 , The inner cross-sectional shape 10 of the grip part 23 essentially corresponds to the outer cross-sectional shape 10 of the main projection 11 and the outer circumferential contour 14 the adapter profile strip 13 ,

In 6 is a cross-sectional view through an inner profile strip 5 a frame strut 3 shown. The cut is in a plane in which the hatched inner profile strip 5 not in the outside profile bar shown without hatching 4 intervenes. It also shows a state in which the adapter profile strip 13 on the auxiliary projection 12 the inner profile strip 5 is plugged. It can be seen that the cross-sectional contour 14 the adapter profile strip 13 essentially the cross-sectional shape 10 of the main projection 11 equivalent. Also on the left side is the 6 to recognize how the end webs 21 in the groove channels 22 should intervene.

In 7 is in the same section plane as in 6 shown as the terminal block 7 on the adapter profile strip 13 is attached, the net 8th between terminal strip 7 and adapter profile bar 13 is fixed.

In 8th is a sectional view through the same frame strut 3 shown, however, in an area where the inner profile strip 5 in the outer profile strip 4 is inserted. It can be seen that in this area the terminal block 7 directly on the main projection 11 the outer profile strip 4 for fixing the net 8th is plugged. The terminal block 7 is therefore about the complete extension of the frame strut 3 formed in one piece.

In 9 is also another sectional view through the frame strut 3 shown, in an area where the inner profile strip 5 not in the outer profile strip 4 is inserted. It can be seen here that the terminal block 7 directly on the main projection 11 for fixing the net 8th is plugged.

The adapter profile bar 13 now ensures, on the one hand, that the terminal strip 7 as a part of the overall length 16 a frame strut 3 can be plugged. In addition, the adapter profile strip causes 13 that with mounted corner connectors 25 the frame strut 3 not by further insertion of the inner profile strip 5 in the outer profile strip 4 can be reduced because the front sides of the adapter profile strip 13 on the one hand with the corner connector 25 comes into contact and on the other hand in abutment with the front of the main projection 11 the outer profile strip 4 comes. The minimum size of the tenter 2 is thus by the lengths 15 the adapter profile strips 13 specified while enlarging the tenter 2 by defining the network 8th on the frame struts 3 is prevented.

In 10 is a detail view of a frame strut 3 represented by a handle 18 is appropriate. The frame strut 3 is shown in a state in which the terminal block 7 not yet appropriate. The handle 18 is with a foot-side section 19 over the auxiliary projection 12 the inner profile strip 5 placed. At a front end is the foot-side section 19 of the handle 18 on one end face of the outer profile strip 4 at and at an opposite end face is the foot-side section 19 of the handle 18 on one end face of the adapter profile strip 13 at. The width of the foot-side section 19 of the handle 18 in the direction of the longitudinal extension of the frame strut 3 Thus, together with the length of the adapter profile strip 13 the maximum insertion depth of the inner profile strip 5 in the outer profile strip 4 in front. For further assembly of the clamping frame, the in 10 not shown terminal strip 7 with a section over the main projection 11 the outer profile strip, with another section on the foot-side section 19 of the handle 18 and with another subsection about the on the auxiliary projection 12 attached adapter profile strip 13 establishing the network 8th clamped. The terminal block 7 thus fixes the handle 18 on the frame strut 3 , so for the assembly of the handle 18 no additional tool is needed.
