Frame system for attaching a shield, in particular an insect screen, in a building opening in a confined space

Field of the invention

The invention relates to a frame system for attaching a shield, in particular an insect screen, in a building opening, such as in a building. a door or a window. The frame system according to the invention can also be fastened in a confined space in a building opening and is characterized by a simple assembly and by easy manufacture due to relatively few individual parts. According to a further aspect of the invention, this relates to a method for attaching a shield, in particular an insect screen, in a building opening.

State of the art

Various types of frame systems for attaching a shield in or on a building opening, such as a window or a door, are known in the prior art. Such a shield may be any type of shield. Examples of shields are, for example, insect screens, particle guards and sun and privacy systems. These shields usually have a protective fabric in the form of an insect or particle protection grid or a protective fabric. In the present case, correspondingly suitable knitted fabrics, knitted fabrics, metal meshes, etc. are also referred to as protective fabrics. The shield with the respective protective fabric is usually clamped in a frame, which in turn is arranged in or on a building opening, such as a window or a door. Usually, such a frame is at a building opening screwed tight, glued or clamped. However, the assembly process is often not very user-friendly and, moreover, does not necessarily permit installation in the smallest of spaces, ie even in very small and less profiled building openings.

Description of the invention

It is the object of the present invention to overcome the above-mentioned disadvantages of the prior art and in particular to provide a frame system for attaching a shield in a building opening, which can be fastened in or on such a building opening in a confined space, by a simple assembly and an easy manufacturability distinguishes. In addition, the frame system should be inexpensive to produce.

The object is solved by the subject matter of independent claims 1 and 21. Dependent claims are directed to particularly advantageous embodiments of the invention.

According to a first aspect of the invention, this relates to a frame system for fixing a shield in or on a building opening. The shield may be any type of shield. In particular, it may be an insect screen, a particle guard, a sun or screen, etc. In the following, a building opening is understood to mean any type of building opening, typically a window or a door. The frame system according to the invention has at least three frame elements for stable shaping of the frame in the installed state. Alternatively, however, it is also possible that the frame has four frame elements and forms a full frame instead of a three-element subframe. The at least three frame elements are two opposing side elements and a connecting element connecting the two side elements. Preferably, the connecting element is an upper connecting element, wherein the term "above" refers to the orientation within the building opening in the assembled state of the frame. Preferably, the two side elements in the installed state of the frame are vertical and thus oriented laterally in a building opening. In principle, however, it is also possible that the three frame elements with respect to the just described Scenarios rotated, especially rotated by 90 ° or even 180 ° in a building opening. The two side elements and / or the connecting element may be formed in one or more parts. You can for better stability of the frame directly or indirectly connected to each other, for example, inserted into each other, connected by connectors, glued, bolted, etc., be formed. Alternatively, the two side elements and the connecting element can also only loosely adjoin one another, and it is advantageous if there are no gaps or gaps between them in order not to restrict the function of the shielding effect. In the latter case, the frame can then obtain its stability by fastening the frame elements in the building opening.

The frame system according to the invention further comprises a shield which is clamped or clamped in the frame. The shield is - as already stated in the general part - an insect screen, a particle screen, a sunscreen or privacy system. Its protective fabric may have the properties already described in the general part relating to the prior art. Preferably, the shield is rectangular; but it can also have other shapes. It may be completely or partially fringed or unhemmed.

According to the invention, the two side elements each have two mutually substantially parallel guides, in which the shield is feasible or guided with their sides. The guides can be any kind of leadership. It is crucial that the provision of the guides a correct placement of the shield is achieved on the side elements.

According to a preferred embodiment of the invention, the guide elements are guide rails, in particular double guide rails. These can be realized, for example, in the side elements so that the guidance takes place within the side elements. Alternatively, the guide members may also protrude from the side members toward a center of the shield. If the guide rails are double guide rails, then a guide rail has two guides running parallel to one another. It is preferred that the guides in the two side elements each extend continuously. Alternatively, it is also conceivable that the guides are provided only in sections or selectively. In the latter case, it could, for example to act various locking positions in which a shield connected to the side elements undergoes guidance. The two guides are substantially parallel to each other. This means that the direction in which it is guided is parallel for both guides. However, in the case of punctually provided guides this does not necessarily mean that the guide points are always close to each other, they may well have a certain offset from one another along the longitudinal axis of the side elements.

According to the invention, the connecting element has a deflection device, around which the shield is deflectable or deflected. Such a deflection device causes a change of direction of the direction of the shield. The deflection device may be any type of deflection device. In this case, the deflection can be formed in one or more parts; it can be firmly integrated in the connecting element or be provided separately. Further preferred embodiments of the deflection devices are described below.

The frame system according to the invention allows that in the assembled state of the frame by shifting the shield in the guides, wherein the connecting element parallel edges of the shield toward the connecting element or be moved away from it, creates a variable in its surface shielding. According to the invention, a part of the shield is thus guided in a first guide or can be guided in a first guide, is subsequently deflected by a deflecting device or can be deflected by the latter, and is guided in the second guide after leaving the deflecting device Leadership be led. The two substantially parallel guides preferably extend in each case along the entire longitudinal direction of the respective side element, either continuously or in an interrupted manner. The shielding region is understood to be that region of the frame system which ensures the shielding effect in the assembled state of the frame system. Due to the displaceability of the connecting element parallel to the edges of the shield may be in the shielding area is an area in which the shield is wholly or partially double-layered. It is also possible that the shielding area is formed by a shield arranged only in one layer. Preferably, in the assembled state by a user, the position of the parallel edges of the shield to the upper ren connecting element is adjusted so that the shield is taut, that is guided without bumps and corrugations, from the first parallel edge over the deflection and the second edge parallel to the connecting element.

According to a preferred embodiment of the invention, the area of the variable shielding area is at most at least as large as the entire frame area, and the area of the variable shielding area is minimally at least as large as half the frame area. The entire frame surface is understood to be the entire region spanned by the frame elements, regardless of which part of the frame surface is covered by the shielding. It is preferable that the area of the variable shielding area is at most equal to the entire frame area, and the area of the variable shielding area is at least as large as half the frame area. Illustratively, this means that in the frame system according to the invention between a perfect shield and a shield, which makes up only half the frame area can be selected. The transitions between these two extreme positions can be adjusted steplessly or in steps.

According to a preferred embodiment of the invention, the shield is arranged in the frame at least partially double-layered in the case of the provision of a non-maximum shielding area in the frame. In this case, if the area of the variable shielding region varies between the entire frame surface on the one hand and the half frame surface on the other hand, then the shielding surface, which corresponds to half the entire frame surface, completely has a double-layered arrangement of the shielding. Conversely, in the case of maximum shielding, the shield is preferably arranged or formed completely in one layer. In principle, it is also possible that the shield has an excess length with respect to the open side of the frame; However, it is preferred that also on the open side of the frame, the shield with the building opening, in which the frame is inserted or can be inserted, completes.

According to a preferred embodiment of the invention, the guide elements are guide rails, in particular double guide rails. In each case two guide rails, each substantially parallel to each other, are arranged per guide rail. de guides provided, these may extend into the side elements in or protrude from this. However, in order to provide a particularly space-saving frame system, it is preferred that the double guide rails are designed as hollow guides, ie according to the first described variant, in the side elements.

According to a particularly preferred embodiment of the invention, a guide depth of the guide rails is substantially greater than an opening width of the guide rails for receiving the sides of the shield. Preferably, the guide depth of the guide rails is identical and substantially constant; but the depth of leadership can also vary. The depth of an overlap area between the side element with the guide rail and the shield guided in the guide is understood as the depth of the guide. The opening width of the guide rails is understood to mean the distance between the two sides of a respective guide rail which guide the shielding. It is preferable that the guide depth is at least a factor of 15, preferably at least a factor of 20 or at least a factor of 25 greater than the previously defined opening width of the guide rails.

According to a preferred embodiment, the guides in the double guide rails are each formed as a narrow, relatively deep gap. The above-described dimensions of leadership depth to the opening width allow for a particularly secure guidance of the shield. On the other hand, the shield lies well in the guide at the edge regions, so that already by this guide alone a good seal of the shield takes place towards the side member. This is particularly important in the case of an insect screen or particle protection grid as a shield of great importance or advantage. This also allows a very space-saving design of the frame system according to the invention. The described design of the frame system therefore makes it possible to provide no additional sealing elements on the sides of the shield. In particular, can be dispensed with the typical brush projections in known insect screens or particle guards. In this way, the frame system according to the invention is also less fragmented or multi-part and therefore can be manufactured and assembled easier.

According to a further preferred embodiment of the invention, the deflection device is a deflection roller. This pulley can be designed as a hollow body or compact. It can be formed in one piece or in several parts. loading Preferably, the guide roller is cylindrical. The deflection roller may be provided separately or fixed or inseparable in or on the connecting element. For example, it could be hung on or near the upper connecting element, coming from below.

According to a preferred embodiment of the invention, the deflection roller is laterally inserted into an opening of the connecting element. The deflection roller can be inserted or pushed completely into the connecting element in this way. Side means in this context in the direction of the longitudinal direction of the connecting element. Alternatively, it would also be conceivable that the deflection roller is pushed from above or below into an opening of the connecting element, i. is introduced from a direction orthogonal to the longitudinal direction of the connecting element in the connecting element. For example, the connecting element could have a slot in the longitudinal direction, which can be bent so that the deflection roller could be pushed or pushed into an opening adapted to the shape of the deflection roller, in particular a cylindrical opening within the connecting element. For reasons of stability, however, it is advantageous to insert the deflection roller into an opening of the connecting element from the side along the longitudinal direction of the connecting element.

According to a further preferred embodiment of the invention, the connecting element has a substantially cylindrical cavity and a substantially parallelepiped-shaped cavity, each extending in the longitudinal direction of the connecting element and adjacent to each other, wherein the two cavities in a border region to each other have a passage. The cylindrical cavity serves to receive the preferably cylindrical deflection roller. In order for the shielding to be able to be guided around the inserted deflecting roller at all, it is necessary for the connecting element to have in its longitudinal direction an opening region through which the shielding can be guided. The provision of a cylindrical cavity and the provision of an adjoining substantially cuboidal cavity allow a particularly stable formation of the connecting element and a particularly good guidance of the guided shield in the region of the connecting element. According to a further preferred embodiment of the invention, the shield is connected or connectable at its upper and / or lower edge to an associated grip element. The gripping element is preferably a grip rail, which preferably extends substantially along the entire upper and / or lower edge of the shield. However, this is not mandatory. The grip member or grip rail allows easy gripping of the top and bottom edges of the shield, respectively, to easily adjust the size of the variable shielding area or area thereof by a user. The handle rail is preferably rigid, but may have some flexibility. The handle rail preferably has a bar extending in the assembled state perpendicular to the surface in which the shield is mounted. In particular, it can also be curved and transition from a protruding region as described above into a region which is planar with respect to the shield in the assembled state. The projection allows for a simple gripping the handle rail. Furthermore, the handle rail can be brought into abutment with the connecting element or the deflection device integrated therein and serves as a stopper so as not to accidentally move the shield too far towards the deflection device or even to pull it completely out of the connecting element. The region projecting perpendicularly to the surface, which is clamped by the shield in the assembled state, does not extend into the guides of the side elements. Preferably, it closes off laterally with the beginning of the guides.

According to a particularly preferred embodiment of the invention, the handle rail has a cavity into which a clamping element at least partially wrapped with the edge of the shield is inserted or inserted, so that the edge of the shield is connected or connectable to the handle rail. The connection between the handle rail and shield so done by clamping. Preferably, the handle rail has a passage opening to the cavity, through which the shield is guided or passed. Preferably, the clamping element is locked in the mounted state in the handle rail or can lock in the handle rail. For this purpose, for example, clamping element and handle rail with mutually corresponding projections or notches may be formed as locking means.

The clamping element itself is preferably in one piece and preferably compact. It is at least partially wrappable or wrapped with the shield, ie the Shielding may be at least partially formed circumferentially around the clamping element. Preferably, more than half of the outer surface of the clamping element is wrapped with the shield. This can be ensured for example by a corresponding shaping of the clamping element. In the case of a cross-sectionally approximately rod-shaped clamping element can be achieved by a corresponding herumumeln or wrapping around the shielding and pinching by inserting the clamping element together with shielding in a cavity of the handle rail a particularly good clamping effect, as within the cavity, the orientation of the shield changes or the shield is folded directionally. This complicates in particular an unwanted pulling out of the shield from the handle rail with a strong pull on the handle rail. This effect can be further enhanced by the provision of a pointed area in the area of the directional distribution.

The grip element or the grip rail itself can, in addition to the structural properties already described above, be substantially rigid and at least partially flexible and / or hinged. If the gripping element is rigid, the insertion or insertion of the clamping element into the cavity can best be done laterally, i. take place along the longitudinal axis of the handle element. If the gripping element in the region of an opening for carrying out the shielding is flexible, then it can be bent up to insert the clamping element there. If the grip element can be opened, then the clamping element can be very easily inserted into the grip element. Preferably then there are also on the handle member securing means for a secure closure after refolding the handle member, e.g. a click or click mechanism.

According to a further preferred embodiment, the clamping element is glued to the shield in the region of the edge of the shield or festklebbar. For this purpose, for example, adhesive strips may be attached to the clamping element, which are preferably provided with a peelable protective cover. In the case of a clamping element with a substantially rod-shaped cross-section, the adhesive strips can be present on both sides of the clamping element or else only on one side of the clamping element. The sticking of the shield to the clamping element allows a simpler and more accurate installation of the frame system according to the invention. According to a further embodiment of the invention, the shield has both at its upper and at its lower edge, thus both parallel to the connecting element edges in the mounted state, each a handle element, wherein the two handle elements based on the shield when they are completely flat is spread or would be spread, are oriented differently with respect to the front or back of the shield or would be. For example, if the handle member has a handle bar protruding from the plane of the shield, the bar of one handle member would protrude toward the front of the shield while the other bar protrudes toward the back of the shield. If the shield is guided over the deflection device, the described orientation of the grip elements causes both grip elements to be gripped by a user in the same way, ie from the same direction. Furthermore, the orientation described allows an overall space-saving design of the frame system, since the depth of the frame system is thereby lower overall. Also, the handle elements can be particularly easily passed to the shield, without getting caught for example with this.

According to a further preferred embodiment of the invention, the side elements and / or the connecting element are double-walled. The side elements and / or the connecting element preferably have cavities for this purpose. In this way, it is possible to produce the side elements and / or the connecting element particularly dimensionally stable and yet light and overall in small dimensions. Preferably, the side elements and / or the connecting element made of plastic are wholly or partly made.

In accordance with a further preferred embodiment of the invention, the side elements and / or the connecting element have notches for fixing means for fastening the frame system in a building opening. Preferably, these indentations are substantially continuous, ie they essentially have the form of rails or bars. The indentations make it easier to position the fixation means in the desired target position for fixation purposes. If the indentations are substantially continuous, the exact positioning of the fixing means within the indentations can be freely selected by a user of the frame system according to the invention. This is particularly advantageous if, prior to mounting the frame system according to the invention, the dimensions tions of the side elements and / or the connecting element to the respective dimensions of the building opening must first be adapted, so that it would be difficult to set the final position of fixing means such as screws final factory already in advance of a montage.

According to a further preferred embodiment of the invention, the frame system has fixing means for fastening the frame system in a building opening. The fixatives may be any type of fixative; it is preferably screws.

According to a further aspect of the invention, this relates to a method for mounting a frame system for attaching a shield, in particular an insect screen, in a building opening. The frame system to be mounted may be, for example, the frame system which has been described in more detail above and is also defined in more detail in claims 1 to 20. All the characteristics of the frame system and its components may be the same as those of the frame system described above; however, this is not necessarily the case.

According to the method according to the invention for mounting a frame system, first a shield, two side elements, a connecting element with an associated deflection device and two grip elements are provided. The shield may in particular be an insect screen; but it can also be other types of shields, such as a particle guard, a sunscreen system or a blind system. The shield is clamped in a frame. The two side elements each have two substantially mutually parallel guides, in which sides of the shield are feasible. The guides can be, for example, guide rails, in particular double guide rails. The guides extend in the longitudinal direction of the side elements, preferably along the entire side elements, and are then aligned parallel to each other. In a direction of penetration through a building opening, the two parallel guides are, for example, behind one another. The connecting element, together with the two side elements, clamps a frame or at least one subframe and has an associated deflecting device which can be mounted in the connecting element and around which the shield is deflectable. In particular, the connecting element for this purpose may have an opening adapted to the deflection for receiving the deflection device. The deflection device is, for example, a deflection roller. The two grip elements serve to better grip the shield.

After providing the elements of the frame system described above, the actual assembly steps are carried out: The two grip elements are attached to two opposite edges of the shield. This can be done, for example, with the aid of the above-described clamping element. In a further method step, the shielding is simply folded around the deflection device. The shield is thus placed around the deflection around; If the covering of the shielding takes place in a central region of the shielding, then the shielding is at least partially double-layered after the shielding has been folded over the deflecting device. In a further method step, the deflection device, including the surrounding shielding, is inserted into the connecting element, so that on both sides of the deflection device part of the shielding with the grip elements attached thereto hangs down. The meaning of the term "hanging down" is not to be taken literally. Of course, the insertion process can also be lying on a flat surface, such as a table or floor. In this case, parts of the shield would come to lie on one another in two layers. In a further method step, the fastening of the connecting element takes place in a building opening such as a door or a window. The attachment can be done for example by tightening the connecting element, other types of fastening are conceivable. In a further optional method step, the shielding is pulled out on one side so that a grip element comes into abutment with the connecting element or the deflecting device. Further removal of the shield is then no longer possible. This process step facilitates the process step described below. In a further method step, the side elements are placed in the building opening and there is a fitting of the side elements facing edges of the shield in each case in one of the two guides. Which of the two guides is involved inevitably results from whether and, in case of doubt, to what extent the shield has been pulled out in the optional method step described above. In a further method step, the side elements are fastened in the building opening, for example screwed tight. If the two gripping elements in the assembled state are in front of the clamped surface of the shield, it is again advisable to fix the two gripping elements in the orientation described in claim 16 on the shield. Furthermore, it is then recommended that a fitter grasps the rear handle rail from the operator side of the frame system according to the invention and pulls out the shield on one side. In this case, then a problem-free adjustment of the surface to be shielded is ensured by simply gripping the second, in front of the operator side handle element.

The fastening of the grip elements, in particular a grip rail to edges of the shield can - as already described above - see. also claims 12 and 13 - done by gluing and clamping.

The present invention will be better understood with the aid of the attached drawings. Showing:

1 shows a frontal view of a mounted frame system 1 according to the invention. The frame of the frame system 1 has three frame elements: a first side element 3, a second side element 4 and an upper connection element 5 Frame elements together span the frame or a subframe and are fastened with fastening means, screws 23 in the case shown, in or on a building opening (not shown). Only indicated in Fig. 1, the shield 2. The shield 2 is deflected in the connecting element 5 and is laterally fitted in the side members 3 and 4. The free edges of the shield 2, which extend substantially parallel to the longitudinal axis of the upper connecting element 5, are provided with grip rails 14 and 15. The shielding region, which is shown in FIG. 1 or the associated FIG. 2, is not identical to the entire surface which is spanned by the frame as a whole: the entire frame surface HF results in FIG. 1 as product of the frame width HB with the frame height HR. The area F of the shielding area, on the other hand, is the product of the height H of the shielding area with the width B of the shielding area. The height H of the shielding area is composed of the height h1 and the height h2, wherein along the height h1 the shield 2 has a single layer, but along the height h2 is double-layered. By gripping the grip rails 14 and 15, which are connected to the edges 36 and 35 of the shield and a corresponding movement of the handle rails 14 and 15 on the upper connecting element 5 to or away in the (not in the figures 1 and 2) recognizable) double guide rails of the side members 3 and 4, the area F of the shielding region can be varied. In the example shown, the area of the variable shielding area F is at most as large as the entire frame area HF, and the area F of the variable shielding area is minimally as large as half the frame area HF. In addition, the equation HR = 2 h2 + h1 applies exactly or approximately.

Fig. 2 shows the frame system shown in Fig. 1 in a slightly perspective view. In this perspective view, it can be seen in particular that the grip rails 14 and 15 have a grip strip, which assigns in the example shown to the viewer of FIG. It should again be noted that the shield 2 is shown in Figures 1 and 2 only schematically or only indicated. The oblique lines in the figures do not indicate the edges of the shield 2, but merely indicate the perspective view in the figures. The lateral edges of the shield 2 are guided as mentioned in the double guide rails of the side elements 3 and 4, there is thus no gap between the side members 3 and 4 and the shield second Fig. 3 shows a perspective view of a side member 4 with a double guide rail. Fig. 4 shows a cross section through the side member shown in Fig. 3. The side member 4 is formed in the embodiment shown in angled shape. It has two parallel guides 6, which extend along the longitudinal axis of the side member 4 over the entire length of the side member 4. In these guides 6, the shield 2 is received and guided. The area of the side element 4, which does not include guides 6, has a plurality of cavities 19. The side member 4 is therefore designed double-walled, which allows to obtain a dimensionally stable side member 4, even if it is made of inexpensive plastic.

The guides 6 are designed as very deep and at the same time narrow guides 6: The guide depth T is substantially greater than the opening width S or S 'of the guides 6. Preferably, the guide depth T moves numerically in the range 20 to 40 mm, preferably in the range of 28mm to 32mm, most preferably at about 30mm. The opening width S preferably moves in the numerical range 1, 5 mm to 2, 5 mm, most preferably at about 2.0 mm. The total width G is preferably in the range of 7 mm to 15 mm, preferably in the range of 9 mm to 11 mm. The opening widths S and S 'are preferably the same size, but they can also be configured differently sized. Both guide depth T and opening widths S are preferably the same along the entire guide 6, but they can also vary. The formation of the guides 6 as a very deep and at the same time very narrow gap makes it possible to achieve a good seal or a good seal when guiding a shield 2. In particular, it is not necessary for sealing purposes (especially if the screen is designed as an insect screen or particle screen) to attach additional sealing elements such as small brushes to edges of the screen. The frame system according to the invention is therefore less fragmented, simpler and easier to manufacture and is also less susceptible to wear. Also, it can be carried out very space-saving and is also suitable for mounting in the narrowest space.

For fastening the side element 4 in or at a building opening, notches 22 can be seen in FIGS. 3 and 4, which extend continuously along the entire length of the side element 4. The notches 22 define attachment positions and allow for easier attachment of the side members 3 or 4 in building openings. It is up to the installer, at exactly which position along the extended notches 22 he wants to make a fixture; this increases the flexibility in the assembly process and takes into account the fact that side elements 3 and 4 and / or an upper connecting element 5 must first be shortened to an appropriate length of the building opening before actual assembly in a building opening.

5 shows a sectional view through a connecting element 5 with a deflection roller 7. The deflection roller 7 is located in a cylindrical cavity 1 1 in the connecting element 5. At this cylindrical cavity 11 is adjacent to a substantially parallelepiped cavity 12, both cavities 1 1 and 12 are interconnected by a passage 13. Around the guide roller 11, the shield 2 (not shown) is guided around, this leaves the cylindrical cavity 1 1 through the passage 13 and the parallelepiped cavity 12. The guide roller 7 can in a connecting element 5, which is shown in Fig. 5, laterally be inserted; Alternatively, it would also be conceivable to form the passage 13 so that the walls of the passage 13 are temporarily deformable by a press-fit, so that the guide roller 7 can be inserted through a corresponding passage from below into a corresponding cavity 11. In the upper region of the connecting element 5 in turn a plurality of cavities 20 are provided which increase the dimensional stability of the connecting element 5, in particular if this is made of inexpensive plastic. In addition, notches 22, which preferably extend along the entire longitudinal axis of the connecting element 5, can be seen in FIG. 5, so that fastening positions in the notches 22 can be freely selected by a fitter.

Fig. 6 shows a section through a handle rail 14 with an opening 21 for a clamping element (see Fig .. 7). The handle rail 14 has a slightly pre-bent handle portion 30 on which a user of the frame system according to the invention engages this and adjusts the variable shielding area. The cavity 21 is intended to receive the clamping element 24 and has a corresponding shape. The clamping element 24 is of rod-shaped design in cross-section and has a notch 18 which can latch on the associated locking lug 17 in the cavity 21 of the handle rail 14. Furthermore, the cavity 21 and the clamping rail 24 are provided with a tip 26 and 25, respectively. To secure the shield 2 to the handle rail 14, an edge of the shield 2 is wound around the clamping element 24. Of the Winding area is limited in the example shown by a projection 27 on the clamping element 24. For better attachment of the shield 2 to the clamping element 24, an adhesive zone 32 is provided, so that the shield 2 can be glued to the clamping rail 24. Of course, such an adhesive zone may also be provided on the other side (with respect to the tip 25) of the clamping element 24.

After the shield 2 has been fastened to the clamping rail 24 as described above, the composition shown in Fig. 8 is pushed into the handle rail 14 through the passage opening 16. Preferably, this insertion is lateral, i. along the longitudinal axis of the clamping rail 24. In this case, the clamping rail 24 may be rigid or slightly flexible, e.g. made of cheap plastic, be formed. The clamping rail 24 is inserted into the cavity 21 so that the tip 25 of the clamping rail comes to lie in the tip 26 of the cavity 21 of the handle rail 14. In this case, the projection 17 of the handle rail 14 locks with the notch 18 of the clamping rail 24. The shield 2 winds through the passage opening 16 addition (the serrated shape 31, which can be seen in Fig. 8, receives the shield 2 only when inserting Clamping element 24 together with shield 2 in the handle rail 14). Due to the fact that the shield 2 is deflected relative to the clamping element 24, an unwanted slipping out of the shield 2 is prevented even with strong train on the handle rail 14. The tip configuration of the lower region of the clamping rail 24 with the tip 25 also contributes to this.

Alternatively, the handle rail 14 may be configured to be hinged to receive the clamping rail 24 therein. In this case, unfolding is preferably carried out so that the already existing opening 16, through which the shield 2 is to be passed, is enlarged by the unfolding. For safe closing of the handle rail 14, for example, a locking or clicking mechanism may be provided, other security mechanisms are conceivable. Another alternative is to manufacture the handle rail 14 at least in partial areas of a sufficiently elastic material, so that the handle rail 14 can be bent in the region of the opening 16 for insertion of the clamping rail 24. Due to the elasticity, this opening 16 closes after insertion at least partially automatically again. But it is also possible to provide further securing elements such as a latching or click mechanism for a secure closure. With the aid of the frame system according to the invention, a shield can be fastened in a confined space in a building opening. In addition, the installation is relatively simple, since relatively few items must be assembled into a frame. Furthermore, the manufacturability of the frame system according to the invention is facilitated due to the reduced small parts, which also leads to a cost reduction.
