Description

Usual window grilles consist of several tubes or solid bars, which are welded together. These are bolted in or in front of a window reveal with welded tabs or glued with welded wall anchors (dowels or rods). Furthermore, there are window grates to pull apart to cover different soffit widths. These lattices are complex and are mainly made by hand. The assembly takes place at the manufacturer in the workshop by means of welding, grinding and / or drilling, since the customer can not be expected to do this work for safety reasons. Consequently, the grids usually have to be shipped by freight carrier at a high cost because they are assembled and thus bulky. The use of a cheaper parcel service is therefore often not possible. The window grille is bolted after delivery by a specialist company, which requires high expertise. This delays and increases the cost of attaching the grid to self-labor.

It is also known to introduce into an in or in front of the window reveal permanently mounted tube an internal roll-steel rod, which rotates when sawing, so that a severing of the tube by means of a normal saw is not possible or at least difficult. However, this solution is expensive and therefore expensive. On the other hand, permanently welded bars enable a faster sawing, which is why grids of this type usually do not pass an anti-burglary test with proof.

The invention is therefore based on the object to avoid the above disadvantages in the prior art. It is a system for burglary protection for a window and a window grille are provided with the system, which is simple in each case with high burglary protection and thus can be manufactured industrially and can be assembled with low expertise at the customer by a fitter or the customer himself and assembled , Furthermore, the system for burglary protection for a window and the window grid with the system should be able to be sent by parcel service to the customer.

The object is solved by the subject matter of claim 1. Advantageous embodiments of the invention can be found in the subclaims.

According to the invention, a system for burglary protection is provided for a window, wherein the system comprises at least two system pipes and at least one rod, wherein the two system pipes are designed to be fixable respectively to a soffit of the window or a facade surrounding the window and between the two System rod arranged rod in a movement of the rod along and perpendicular to a longitudinal axis of the rod limited and rotatable to store the longitudinal axis. The longitudinal axis of the rod is substantially perpendicular to a first tube axis of the first system tube and to a second tube axis of the second system tube when a first end of the rod is received in the first system tube and abuts the first system tube and a second end of the rod in the second system pipe is received and rests against the second system pipe to rotatably support the rod.

By the first and second ends of the rod is meant an end portion of the rod, in particular the end portion of the rod which is inserted into the first and / or second system pipe when the rod is arranged between both system pipes. The two system tubes can have an elongated shape and, for example, cylindrical or square, in particular rectangular or square, be formed. Both system tubes can in particular have the same shape, dimensions and the same material, that is to say be formed similar to one another. The rod can also be elongated, in particular straight, be formed and made of a solid material. Both the system pipes and the rod can be industrially manufactured due to the simplicity of their construction and arrive in parts by parcel service to the customer.

For example, a plurality of bars may be arranged as bars between two system tubes and this window grid may be mounted in a window reveal, for example, a basement window. For this purpose, each of the two system pipes can be fastened with, for example, three wall anchors by means of a core hole in masonry of the soffit with 2-component injection mortar or another adhesive, so that the tubes are parallel to each other and perpendicular to the mutually parallel rods and wall anchors. The rods can thus be stored by the system pipes, which in turn are fixed by the wall anchors on the soffit. The wall anchors and rods are separated from each other at the ends by a system tube and indirectly connected to each other.

Since the wall anchor and the bars are fixed to each other by the system tubes or at least in their mobility, for example laterally, are severely limited, the window bars would come out without screws. However, this would be a weak point, since you could fix the grid bars relative to the system pipes rigidly, for example by means of conventional M8 screws, so that they are not rotatable, which would facilitate a sawing of the bars against an existing rotation of the rods.

To prevent this, according to the invention, for example, stainless steel countersunk screws, possibly with stainless steel countersunk discs, in particular with screw locking compound, used in existing at the ends of the bars drill holes and screwed with a small torque of only 1 Nm +/- 0.2 Nm. The low torque of the screwed connection causes the stainless steel washer washers to lie only lightly and the bars can be turned by hand. The ends of the bars are thus received in the system tubes and applied only to the system tubes instead of being rigidly fixed to the system tubes to allow rotation of the bars by an external torque. The inclusion of an inner tube in an outer tube is unnecessary. Also, a latching and / or snap connection between the end of the rod and the respective system pipe for rotatable contact of the rod on the system pipe is possible. Due to the inclusion and conditioning of each end of the two system tubes vertically aligned rod in the system tubes results in a simple and rotatable mounting of the rod such that it does not require any internal rolling steel rod. Instead, the outer tube itself is rotatable and can also be present as a rod / rod in solid material.

The system of the recorded in the system pipes ends on the system pipes can be done by loose placement of the rod, for example, in openings of the system pipes. The system can also be carried out under a contact pressure or pull of the rod to the respective system pipe. If, for example, the ends of the rod pull the system tubes towards each other, thus generating a pressure pull on the tubes, this is possible as long as the pressure pull does not lead to a rigid fixation of the rod on and relative to one or both system tubes, but rather to a bearing of the rod Bar through the two system tubes, in which the rod about the rod longitudinal axis and relative to the two system tubes from an outer torque acting on the rod can be rotated. The same applies to a contact pressure, in which the rod ends generate a force that would move the system tubes away from each other.

In an advantageous embodiment, it is provided that a first inner wall of the first system tube form a first stop for the first end of the rod and a second inner wall of the second system tube form a second stop for the second end of the rod. A common contact pressure of the first end of the rod on the first stop and the second end of the rod on the second stop is positively and / or frictionally set so low that instead of a rigid fixation of the rod and relative to at least one of the two system tubes storage the rod is formed by the two system tubes such that the rod about the longitudinal axis of the rod and relative to the two system tubes from an external, acting on the rod torque, in particular of 20 Nm, preferably at most 10 Nm, more preferably at most 4 Nm , and more preferably at most 2 Nm, ideally substantially 2 Nm, can be rotated. At essentially 2 Nm, the rod can be turned by hand. A rotation of the rod by such a torque makes it difficult to saw the rod significantly against a rigid fixation of the rod and relative to the two system tubes. It can be dispensed with a complicated solution with a tube and internal roll steel rod due to the simple rotatable mounting of the rod. Instead, the rod can be made of a solid material, without sacrificing a high burglary protection.

To generate the common contact pressure of the first end of the rod on the first stop of the first system tube and the second end of the rod to the second stop of the second system tube need not be welded. Rather, it is sufficient to store the rod rotatably only in two system tubes and simply apply the ends of the rod to the attacks. This can be done by a contact pressure generating spacing of the two system tubes to each other at a distance of substantially the rod length and against the soffit.

Alternatively or additionally, the required for a rotatable mounting of the rod common contact pressure can be effected by a releasable and / or adjustable connection of the first end of the rod relative to the first stop and / or the second end of the rod relative to the second stop of the second system tube, for example by a screw connection. A combination of loose rotatable mounting of one end of the rod and at the other end existing screw with defined contact pressure is possible. A latching and / or snap connection between the end of the rod and the stop to achieve the contact pressure of the end of the rod to the stop is also possible. The contact pressure can also be zero N / cm ² at one end or both ends, ie the rod can be guided loosely with respect to one or both stops.

Advantageously, the common contact pressure of the first end of the rod on the first stop and the second end of the rod on the second stop form and or force fit so is set low, that the bearing of the rod is formed by the two system tubes such that the rod can be rotated about the longitudinal axis of the rod and relative to the two system tubes from the outer, acting on the rod torque, by a movement of a saw on a surface of the rod, in particular in an attempt to saw through the rod produced. The rod can thus rotate about its longitudinal axis so that a sawing of the rod is difficult in comparison to a rigid fixation of the rod relative to one of the two or two system tubes. In this way, a high burglary protection is ensured, in particular according to burglary protection test according to DIN EN 1627 RC 2 or RC 3 ,

According to one embodiment of the invention, the first system pipe has a first opening on at least one side opposite the first inner wall and the second system pipe has a second opening on at least one side opposite the second inner wall, and the two system pipes are arranged relative to one another such that the first and second Openings facing each other, wherein the first end of the rod through the first opening and the second end of the rod are guided through the second opening. The mutually facing openings allow a guide or storage of the rod.

In particular, when the rod has an elongate, in particular straight, cylindrical shape, is made of a solid material, such as stainless steel and has a rod diameter which is not greater than a first opening diameter of the first opening and not larger than a second opening diameter of the second opening , the first and second openings together with the first and second stops may form the storage of the rod arranged between the two system pipes. The contact pressure of both ends of the rod on the stops can be zero and between the stops and the ends may each have an air gap. In this embodiment, only the sliding friction between the rod and the supports of the two openings, on which the ends lie in each case, must be overcome in order to rotate the rod. Both system tubes can be designed identically and manufactured industrially. The system can therefore be prefabricated and does not even need to be bolted to the customer. Instead, a required for the arrangement of the rod between the two system tubes for its rotatable mounting fixation of the two system tubes is sufficient relative to the soffit or facade of the window.

It is also possible that, when the rod has an elongate, in particular straight, cylindrical shape is made of a solid material, such as stainless steel, the rod at the first end of the rod has a first threaded bore and at the second end of the rod a second Has a threaded bore, wherein a first bore axis of the first threaded bore and a second bore axis of the second threaded bore aligned with the longitudinal axis of the rod, and serving as the first stop first inner wall has a first passage to the outside with a first diameter and serving as a second stop second inner wall a second passage to the outside with a second diameter. The first diameter is at least as large as a first screw diameter of a first screw guided through the first passage, for example a stainless steel countersunk screw and / or M8 screw, and the second diameter is at least as large as a second screw diameter from the outside through the second Passage passed through the second screw, such as a stainless steel countersunk and / or M8 screw, wherein the first and second screws are each designed to cooperate with the first and second threaded holes frictionally. The contact pressure can be set individually for the first end and / or the second end of the rod due to the degree of screwing. The first and second screws may be similarly formed and / or the first and second diameters may be substantially equal, which facilitates industrial manufacturing, especially at high volumes. The system can therefore be prefabricated and only needs to be screwed. The system can be shipped in parts by parcel service cost-favorable.

When the first screw in the first threaded hole and the second screw in the second threaded hole, in particular with screw locking compound, are used, advantageously the first screw or second screw with a torque of 10 Nm, preferably at most 5 Nm, more preferably at most 2 Nm , and more preferably at most 1 Nm, ideally substantially 1 Nm, in particular both screws substantially the same of these torques, screwed. A rotatability of the rod by hand and / or by an attached to the rod and moving saw, such as a saw or motorized saw, such as a circular or chain saw is ensured. The rod can rotate, making it difficult to saw the rod, with the common contact pressure being generated in a simple and individually adjustable manner at each end of the rod. The torque can be adjusted by hand and / or by means of a torque wrench.

The burglary protection can be further increased if, according to a further embodiment of the invention, a first perforated plate having a first sheet length substantially corresponding to a first system tube length along the first tube axis, into a first cavity of the first system tube and a second perforated plate having a second plate length, which essentially corresponds to a second system tube length along the second tube axis, are loosely inserted into a second cavity of the second system tube such that the first perforated plate is prevented from being removed in any direction along the first tube axis and the second perforated plate is prevented from being removed in any direction are secured to the second tube axis, when the first end of the rod supported by the two system pipes are guided through a first hole in the first perforated plate and the second end of the rod supported by the two system tubes through a second hole in the second perforated plate. Through the perforated plate, a further protection against sawing the system pipe can be achieved. Since the first perforated plate is loosely inserted into the cavity of the first tube, it hooks and / or wedged in a Aufsägeversuch for sawing the first system tube with a saw blade or a saw chain. Accordingly hooked and / or wedged the second perforated plate in a Aufsägeversuch for sawing the second system tube with the saw blade or the saw chain. The first and / or second perforated plate may serve as a template for marking boreholes in the soffit or facade of the window prior to installation of the system or window grid, when a plurality of bars are arranged between both system tubes.

According to a further embodiment, the first system pipe, in particular by means of a first screw with screwing from an outer side of the first system pipe, with at least two first wall anchors, in particular first wall bars, and the second system pipe, in particular by means of a second screw with screwing from an outer side of the second System tube, with at least two second wall anchors, in particular second wall bars, are fixed to the soffit of the window or the facade surrounding the window such that first Wandankerachsen the first wall anchor and second Wandankerachsen the second wall anchor to each other and to the longitudinal axis of the rod substantially parallel and are aligned to the first and second tube axes substantially perpendicular and on the first system tube, the longitudinal axis of the rod between the first wall anchor axes of the first wall anchor and on the second system tube, the longitudinal axis of the rod between the two ten Wandankerachsen the second wall anchors, in particular each substantially centered to the second Wandankerachsen arranged. If the wall anchors each have a length such that the total length of the system with first wall anchors, the first system tubes, the rod, the second system tube and the second wall anchors in the direction of the longitudinal axis of the rod is greater than a soffit width of the soffit of the window in horizontal Direction, reveal width differences, in particular of about 100 mm, can be compensated by means of the first and second wall anchors. Three or more first wall anchors for fixing the first system tube and / or three more second wall anchors for fixing the second system tube may be used to increase the height compared to a fixation with two first and second wall anchors, which is usually the case in the prior art To achieve burglary protection.

In another embodiment, the first and second wall bars each have an elongated, in particular straight, cylindrical shape, are made of a solid material, such as stainless steel, and have at first the first system pipe facing Wandstabenden the first wall bars respectively first Wandstabgewindbohrungen and second to the second System wand facing wall bar ends of the second wall bars respectively second wall bar threaded holes, wherein first Wandstabbohrachsen the first wall bar threaded holes and second Wandstabbohrachsen the second wall bar threaded holes aligned with longitudinal axes of the first and second wall bars. One of the first inner wall opposite side of the first system tube has first Wandstabauslässe outward, each with a first wall bar diameter and a second inner wall opposite side of the second system tube has second Wandstabauslässe outward, each with a second wall bar diameter. The first wall bar diameter is at least as large as a first wall bar screw diameter of first wall bar screws passed externally through the first wall bar passages, for example, stainless steel countersunk screws and / or M8 screws, and the second wall bar diameter is at least as large as a second wall bar diameter from the outside through the second Wandstabdurchlässe passed through second wall bar screws, such as stainless steel countersunk screws and / or M8 screws, wherein the first and second wall bar screws are each designed to frictionally cooperate with the first and second wall bar threaded holes. The first wall bar passages, the second wall bar passages, the first passages, and the second passages may have substantially equal diameters, which simplifies manufacture and, with equal tapped holes in the first and second wall bars and the bar, gives similar parts to the bar support rods and the bar Wandstabschrauben leads.

Also included in the invention is a window screen with the burglary protection system according to the invention for a window as described above. In the window grid are between the first and second system tubes more rods, in particular a total of four identically formed rods arranged. At least three first wall anchors and at least three second wall anchors, in particular three first wall anchors and three second wall anchors, wherein the first and second wall anchors are particularly similar, are present and the first tube axis of the first system tube and the second tube axis of the second system tube are substantially parallel aligned with each other and in the scope of a substantially same rod length of all rods spaced from each other, wherein the longitudinal axis of each rod in a plane spanned by the first and second tube axes system pipe plane or parallel to this plane and aligned the system pipe plane in particular substantially parallel to a window surface of the window is.

The window grille can be mounted in the window reveal especially as a basement window. For this purpose, the three wall anchors per side, so per system pipe, be secured by means of a core hole in the masonry of the soffit or facade with 2-component injection mortar or other adhesive. Since in the fastened state, the wall anchors and the rods can not be moved by the system tubes in the direction of the longitudinal axis of each rod, would come from the window grille without screws. This would be a weak point, since one could fix the rods to the system pipes by means of commercially available screws, for example M8 screws, so that they are no longer rotatable, which makes it possible to saw the rods. To prevent this, screws, in particular stainless steel countersunk screws, in particular with countersunk washers, ideally stainless steel countersunk discs, can be inserted with screw securing mass and can only be screwed in slightly, in particular with a torque of essentially 1 Nm. This allows the Senkunterlegscheibe easily abut the system tube and the rods can be rotated by hand. As a result, the bars or bars can rotate freely. This complicates the burglary protection compared to a rigid fixation of the bars on the system pipes.

Another protection against sawing the system tube is the first or second perforated plate when it is loosely inserted into the cavity of the first system tube or the second system tube. The perforated plate wedged or verhakelt in a Aufsägeversuch with a saw blade or a saw chain. Due to small individual part dimensions of the wall bars, system pipes and bars, the window grille can be sent by parcel without costly costs and shipping. The window grille can be designed and suitable for basement windows from a soffit dimension of 500 mm to 600 mm height and a maximum width of 1050 mm. Longer system pipes and longer bars would also bar higher and wider windows. For the described soffit of max. 600 mm high and 1050 mm wide, a burglary test according to DIN EN 1627 RC2 or RC3 can be made. The entire grid can be made of stainless steel with material number 1.4301, as this material is tougher and rust-free compared to normal steel. The window grill can be made of stainless steel. In addition, a powder coating of the window grid in any RAL color can be done.

A method of constructing the system for burglary protection of a window according to the invention comprises the steps of providing at least two system tubes and at least one rod, fixing the two system tubes respectively to a soffit of the window or a facade surrounding the window, placing the rod between the two System tubes such that the rod is limited in a movement of the rod along and perpendicular to a longitudinal axis of the rod, providing a first inner wall of the first system tube as a first stop for a first end of the rod and a second inner wall of the second system tube as a second stop for a second end of the rod, such that the longitudinal axis of the rod disposed between the two system tubes is substantially perpendicular to a first tube axis of the first system tube and to a second tube axis of the second system tube, setting a common contact pressure of the first end of the rod to d The first stop and the second end of the rod to the second stop is so small that, instead of a rigid fixation of the rod and relative to at least one of the two system tubes, a bearing of the rod through the two system tubes is formed such that the rod around the Longitudinal axis of the rod and relative to the two system tubes from an external, acting on the rod torque, in particular of 20 Nm, preferably at most 10 Nm, more preferably at most 4 Nm, and more preferably at most 2 Nm, ideally substantially 2 Nm, rotated becomes.

The invention also includes the use of the burglary protection system of the present invention for a window grille window comprising the steps of arranging further rods, in particular a total of four similarly shaped rods, between the first and second system tubes, providing at least three first wall anchors and at least three second wall anchors, in particular three first wall anchors and three second wall anchors, wherein the first and second wall anchors are particularly similar aligning the first tube axis of the first system tube and the second tube axis of the second system tube substantially parallel to each other and circumferentially spaced from one another by substantially equal rod length of all the rods, placing the longitudinal axis of each rod in a system tube plane spanned by the first and second tube axes parallel to this plane and align the system pipe plane substantially parallel to a window surface of the window.

A system axis 7 of the first system pipe 5 is parallel to another system axis 17 of the second system pipe 15 aligned, with longitudinal axes of the bars 26 - 29, such as the longitudinal axis 28a of the lattice bar 28 , parallel to each other and perpendicular to both system tube axes 7 . 17 are aligned. Wall anchor axles, such as the wall anchor axles 36a of the wall anchor 36 and 37a of the wall anchor 37 , the wall anchor 33 - 38 are parallel to each other and parallel to the longitudinal axes of the bars 26 - 29 and perpendicular to both system tube axes 7 . 17 the system pipes 5 . 15 aligned.

The window screen 50 Clamps a window grid plane in the X / Y plane that is substantially parallel to the window surface 2c is aligned. The wall anchors 33 - 38 are like the bars 26 - 29 made of solid material in V2A stainless steel and designed as a cylinder with a diameter of 16 mm, for example. Because the wall anchor 33 - 38 are each made of identical parts, the bars 26 - 29 are also made of identical parts and also the system pipes 5 . 15 each made of identical parts, these parts can be industrially manufactured and shipped in unassembled condition by parcel service. The soffit 3 opposite ends of the wall anchor 33 - 35 are connected via screw connections with the first system pipe as well as the soffit 3 opposite ends of the wall anchor 36 - 38 in each case by means of screw connections with the second system pipe 15 are connected. For example, there is a second end 28c of the lattice bar 28 in an opening 19 on an outer side of the second system pipe 15 with a normal vector outwards into the negative X -Direction guided and by means of a screw 28f as a stainless steel countersunk screw M8 is executed, and by means of a Senkunterlegscheibe 28h used as a stainless steel sink washer M8 is executed, on an outer side of the second system pipe 15 with a normal vector in X Direction attached. This is in the area of the second end 28c of the lattice bar 28 a threaded hole, for example, the format M8 for a frictional interaction with the stainless steel countersunk screw 28f with a threaded axis along the longitudinal axis of the grid bar 28 introduced, wherein by the screwing of the rod 28 by means of the stainless steel countersunk screw 28f and the stainless steel sink washer 28h the second end 28c of the lattice bar 28 on a second inner wall 16 of the second grid bar 15 is applied. The second inner wall 16 forms a second stop for the second end 28c of the lattice bar 28 so that the longitudinal axis 28a between the two system pipes 5 . 15 arranged grid bar 28 substantially perpendicular to the second tube axis 17 of the second system pipe 15 stands.

Caused by the screw connection of the second end 28c with the second system pipe 15 by means of the stainless steel countersunk screw 28f and the stainless steel sink washer 28h will be a contact pressure P2 the second end 28c of the lattice bar 28 generated on the second stop, the contact pressure P2 is set so low that, instead of a rigid fixation of the second end 28c of the lattice bar 28 at and relative to the second system pipe 15 a storage of the rod 28 through the second system pipe 15 is formed such that the rod 28 around the longitudinal axis 28a of the staff 28 and relative to the second system pipe 15 from an outer, to the rod 28 acting torque can be rotated. The screw 28f is in the second threaded hole at the second end 28c of the lattice bar 28 used and with a torque of essentially 1 Nm screwed in. Therefore, the grid can be 28 opposite the second system pipe 15 Turn by hand such that by moving a saw on a surface of the rod 28 for example, in an attempt, the staff 28 to cut through, the staff 28 around its longitudinal axis 28a and relative to the system pipe 15 is turned. This makes it difficult to saw the grid bar 28 and thus increases the burglary protection of the window grille 50 opposite a rigidly fixed connection of the grid bar 28 with the second system pipe 15 , The screw connections of the ends of the other grid bars 26 . 27 and 29 with the second system pipe 15 are formed in the same way as the screw of the second end 28c of the lattice bar 28 with the system pipe 15 ,

The burglary protection is at the window grid 50 further increased by having a second perforated plate 22 with a sheet length substantially the length of a system tube along the second tube axis 17 of the second system pipe, into the cavity within the second system pipe 15 is loosely inserted in such a way that the second perforated plate 22 against removal in any direction along the second tube axis 17 is secured, if the second end 28c of the staff 28 through a hole in the second perforated plate 22 is guided. For ease of illustration, the sheet metal hole in the second perforated plate 22 not at the location of the second end 28c in 1 shown, but as a metal hole 22a through which one end of the lattice bar 29 passed through.

A passage 20 in the inner wall 16 is present, which allows a screw through the passage 20 through into a threaded hole (not shown) of the grid bar 29 screwed. On one of the inner wall 16 opposite side 18 of the second system pipe 15 is the grid bar 29 through an opening (not shown) in the cavity of the second system tube 15 guided, with this opening of the opening 19 for the introduction of the second end 28c of the lattice bar 28 in the cavity of the second system tube 15 equivalent. In an attempt, the second system pipe 15 Saw or wedged into the second system pipe 15 loosely inserted perforated plate 22 with a manually or motor-operated saw, such as a circular or chain saw, such that compared to an embodiment of the second system tube 15 without loosely inserted perforated plate 22 the burglary protection is increased. The screw connections of the wall bars 33 - 38 to the respective system pipe 5 . 15 correspond respectively to the screw connection of each end of each grid bar 26 - 29 with the respective system pipe 5 . 15 with the difference that in contrast to the defined contact pressure P2 the ends of the bars 26 - 29 to every system pipe 5 . 15 , which allows upon application of an external torque rotation of the respective rod about its longitudinal axis, the screw connections of the wall anchors 33 - 38 to the respective system pipe 5 . 15 are rigidly fixed executed.

Due to the equal screw connections of the bars and wall anchors to the system pipes, stainless steel countersunk screws and stainless steel countersunk washers can be screwed into the wall anchors 33 - 38 and in the bars 26 - 29 industrially manufactured common parts can be used. Also the openings of the ends of the bars 26 - 29 in the inner wall 16 opposite side 18 for example the opening 19 for the second end 28c of the lattice bar 28 , and the passages through the inner wall 16 , for example, the passage 20 for the end of the lattice bar 29 , are for all bars 26 - 29 executed in the same way, which simplifies the production. Accordingly, the openings through the inner wall 16 and passages for the screw in the inner wall 16 opposite side 18 for the soffit 3 opposite ends of the wall anchor 36 - 38 in the same way in the system pipe 15 designed to simplify manufacturing.

On the second system pipe 15 is the longitudinal axis 28a of the staff 28 between the second wall anchor axes 36a . 37a , the second wall anchor 36 . 37 essentially centered on the second wall anchor axes 36a . 37a arranged. In this way, a weakening of the rigidity of the system pipe 15 through the openings, for example the opening 19 , and the passages, for example the passage 20 , each in the inner wall 16 and the inner wall 16 opposite side 18 of the second system pipe 15 are introduced, optimized or minimally weakened. In addition, due to the same distances, for example, the passage results 20 to the passage 20 adjacent opening for the wall anchor 36 over all bars and wall anchors a simplified production of the system pipe 15 with regard to the Insertion of openings and holes. The system pipe 15 is not directly with the soffit 3 over the wall anchors 36 - 38 connected, but the outside of the system pipe 15 with the inner wall 16 is from the side facing the outer side of the soffit 3 spaced such that a wall anchor length can be chosen so that soffit width differences of about 100 mm by means of the first wall anchor 33 - 35 and the second wall anchor 36 - 38 can be compensated.

The window screen 50 is suitable for basement windows with a reveal size of approx. 500 mm to approx. 600 mm height and a maximum width of approx. 1050 mm. Other soffit dimensions are possible, so longer system tubes 5 . 15 as well as longer bars 26 - 29 higher and / or wider windows without loss of burglar protection can barred. For the described soffit dimension of a maximum of 600 mm height and a maximum width of 1050 mm lies for the window grid 50 a successfully passed burglary protection test according to DIN EN 1627 RC2 or RC3. All elements, including the system tubes, wall anchors and bars, as well as the screws and washers, can be made of stainless steel of material number 1.4301, which is tougher and rust-proof than a normal steel. The window screen 50 is made of stainless steel and can be provided with a powder coating in any RAL color.

With an anchoring of the first system pipe 5 and the second system pipe 15 at the soffit 3 each with three wall anchors results in a higher burglary protection effect than in an anchoring of the first and second system pipes 5 . 15 at the soffit 3 each with only two wall anchors. However, the advantageous effects of the present invention already arise in a system 1 for burglary protection for the window 2 with only one grid bar, for example the grid bar 28 that is between the two system pipes 5 . 15 is arranged. The two system pipes 15 . 25 are executed, each at the soffit 3 or facade 4 of the window 2 be fixable and the between the two system pipes 5 . 15 arranged rod 28 in a movement of the staff 28 along and perpendicular to the longitudinal axis 28a the rod is limited and around this axis 28a rotatably store. The longitudinal axis 28a of the staff 28 is substantially perpendicular to the first tube axis 7 and to the second tube axis 17 if a first end 28b of the staff 28 in the first system pipe 5 is received and on the first system pipe 5 abuts and the second end 28c of the staff 28 into the second system pipe 15 is received and on the second system pipe 5 abuts the rod 28 rotatably store.
