Shock-resistant rolling shutter

The invention relates to a bullet-resistant roller shutter with a door leaf articulated by hinges interconnected door leaf element cn, such as slats or sections, which defines a Torblattebene in the closed state of the roller shutter, the door leaf by means of a drive between an open and a closed position movable back and forth is, wherein the Torblattelemente in cross-section each have cavities, in which an antiballistic insert is inserted. that the deposits of adjacent Torblattelcmente in the closed state of the rolling door in the Torblattebene overlap, so that the door leaf in the closed state over the entire Torblattebene anti-ballistic properties, wherein the insert is plate-shaped, wherein the insert is aligned in the cavity of the Torblattelements obliquely to Torblattebene , and wherein the Torblattelcmente each overlap stepwise in the region of the joints of the door leaf, so that each trailing in the Torblattebene in the closed position insert toraußenseitig the adjacent in the closed position insert overlaps to form a gap.

Roller shutters are used to separate different spatial areas. They often separate an interior from the environment and thereby protect the interior from external influences, such as temperatures, solar radiation or weather, such as wind or rain. However, external influences can also arise from violent effects on the rolling shutter, such as ballistic actions. In order to provide protection in dangerous situations, it is also necessary that the door leaf can be moved quickly between the open and closed state.

However, materials and structures that could provide adequate protection against ballistic impacts generally oppose the high-speed property of a roll-up door, as they significantly increase the weight of the door panel. In particular, the design of the connection points between individual slats of the door leaf involves difficulties. At these points, the individual slats must be designed to be movable relative to one another, since the door leaf can only be deflected or rolled up by an articulated connection of the slats in the open state. So far, the connections between the slats are often designed using elastic rubber profiles. However, with regard to ballistic effects on the roller door, such rubber profiles can offer no protection. An example of a storm and safety roller door reveals the

US 2007/0193701 AI. The roller door described herein includes a plurality of interconnected laminations. To provide a corresponding resistance, the slats are made for example of steel and overlap each other. A sufficient strength of the slats is ensured by the fact that additional Halteelcmente are provided on both sides of a blade.

In order to further increase the resilience of the roll-up door, US 2007/0193701 A1 discloses inserts which can be inserted into the cavities of the slats. These inserts have a solid profile and are held by the Halteelcmente in the slats.

A disadvantage of the disclosed in US 2007/01 3701 AI roller door, however, is the weight of the roller door. To produce the Besehusshemmung here an insert is provided, which fills the entire volume of the lamella. As a result, the total weight of Rolltorcs increases significantly, so that a high-speed property of the roll-up door can be achieved only with great effort. Even with a sufficiently large-sized drive, the high dynamic load due to the high dead weight adversely affects the entire construction of the rolling door, so that the life of the roller shutter decreases sharply. Especially with wide door constructions of eg 8 m or more, the problem also arises that the door leaf sags in the open state of the roller shutter due to the considerable weight. Further, DE 34 02 532 AI discloses a hollow profile roller shutter bar for Sicherheitsrolllädcn. This hollow profile roller shutter bar is at least partially verschen with a filling of a textile composite of fibers of high tensile strength and designed so that overlap the filling areas of adjacent roller shutter bars in the roll.

Similarly, DE 37 43 628 AI discloses a door or a roller shutter from each other partially overlapping hollow profiles. This door or roller shutter is provided for protection against projectiles, explosions or the like with an insert of several layers of a fabric or a knitted fabric of particular aramid. The longitudinal edges of the deposits of adjacent hollow profiles of a roller shutter overlap each other and are stabilized against fraying.

Although the cited references offer a solution to minimize the weight of blinds or the like through the use of liners made of fabric layers, these designs do not provide sufficient protection against ballistic impacts. In particular, the over-the-counter applications of the individual deposits are weak points which can be overcome in the case of a targeted attack and thus can not ensure adequate protection of the interior.

The invention is therefore based on the object to design a roller door such that this not only meets high-speed properties and this has as little weight, but at the same time offers protection against ballistic effects.

This object is achieved by a roller door with the features of claim 1. In particular, this object is achieved in that in the cavity of the Torblattelements also at least one standing at an angle to the insert antiballistic defense strip is arranged, which covers the gap between the deposits of adjacent Torblattelemente in the closed state of Rolltorcs. The anti-ballistic property of the roll-up door is achieved by inserting a plate-shaped insert and at least one defense strip. Due to the special design of the Torblattelemente the anti-ballistic property of the entire roll-up door can be achieved by a very easy to produce additive, the insert and the defense strip. The manufacture of this insert and the at least one Abwehrstrei fens in plate form requires no complicated adaptation processes to the shape of the Torblattelemcnts or other forming steps, such as bending or deep drawing of the material. Thus, the original property of the material can be completely retained and the anti-ballistic property can be ensured.

By using a plate-shaped insert also a very light construction of the door leaf element is achieved. Since a solid profile, that is, a complete filling of the door leaf element is not provided, as in the prior art, each individual door leaf element with a small additional external wall can be designed to be anti-ballistic and thus the entire door leaf structurally light. By this construction, a combination of the anti-ballistic property of the door leaf with the high-speed property of the roll-up door is possible.

The additional formation of at least one angled to insert a Torblattelements defense strip security of the rolling door, that is, the defense against anti-ballistic attacks is increased. The indicated in the prior art vulnerability between the deposits is eliminated by the defense strip. Slanting incident to the Torblatteben projectiles and especially occurring at a small angle to Torblattebene slivers are prevented by the defense strip from penetrating into the protected by the roller shutter interior.

In particular, the gap between two inserts can be covered by the protective strips. This gap is formed between the inserts in the overlapping region of two adjacent door leaf elements. It defines a distance between the inserts perpendicular to the door leaf plane, which extends over the entire width of the door leaf. The gap is in the closed state of Rolltores between an upper end of an insert and a lower end of an insert of the subsequent deposit available. The shape of this gap also changes during the opening and closing operation when the position of the individual Torblattelemente change each other. Due to the at least one defense strip according to the invention, no projectile or splinter can enter the interior through this gap.

Since further overlap the gate leaf elements in each case in the range of joints of the door leaf stepwise, each trailing in the Torblattebene in the closing direction of the insert toraussenseitig may overlap the adjacent in the closing direction insert. This ensures that the door leaf can be easily deflected when opening. An arrangement of the overlap as close as possible to the center of rotation minimizes the space required when deflecting around the respective joint, since thus the ausscherende when deflecting part of the door leaf element is kept low. The space, which must be kept ready for the deflection of the door leaf, can thus be low, making it easy to install the roller shutter in various areas. By overlapping adjacent deposits, the door leaf also provides protection against weather-related influences. Rain, hailstones and the like are rejected on the outside of the door leaf, without being able to flow into the door leaf.

In addition, the plate-shaped design allows easy insertion of the insert in the Torblattelement. As a result, the insert can be easily replaced and thus changed the anti-ballistic property of the roll-up door as needed. In this case, it is conceivable, for example, to replace an insert of the bullet resistance class FB2 according to DIN EN 1522 with the class FB4 according to DIN EN 1522. Thus, the roll-up door could become safer during restless periods, i. after a higher bullet-resistant class, while in normal times an anti-ballistic insert of a lower safety class can be used. The plate-shaped design of the antiballistic insert offers especially in

Connection with the oblique arrangement of the same advantages. In the prior art, lateral inserts are provided to achieve the stability of a Torblattelements. Consequently Here are next to the deposits to achieve the anti-ballistic property further design measures necessary to ensure sufficient stability of the door leaf.

On the other hand, by virtue of the oblique position of the plate-shaped insert according to the invention, both properties are achieved simultaneously. The oblique orientation of the insert, which at the same time has the anti-ballistic property, stiffens the door leaf element, which increases the bending strength of the door leaf element.

As a result of such an increase in the bending stiffness of the individual door leaf elements, the door leaf can thus be made wider overall, that is to say larger in size. A bending of the door leaf in the lintel area due to its own weight can be minimized. This allows the Torblattelement not only easy, but also constructively surprisingly easy to hold. Thus, not only the bending stiffness can be increased by this embodiment of the door leaf element, but also a lightweight door leaf with anti-ballistic properties and thus a bullet-resistant high-speed roller shutter door can be achieved at the same time.

Although DE 202 15 261 U l discloses a bullet-resistant double-armor roller door, in which the door leaf consists of lamellas into which an inclined steel flat can additionally be inserted. In this construction, the anti-ballistic property over the entire door leaf level of the roller shutter is, however, achieved by two successively arranged door leaves, whereby the weak point at the interface between the individual slats can be countered. By a staggered arrangement of the slats of the two door leaves relative to each other, a slat covers each of the interface between two slats of the other door leaf.

However, this arrangement of two door leaves brings significant disadvantages of the entire system roller door with it. On the one hand increases the space requirement for the roller door, since instead of a door leaf two door leaves must be installed one behind the other. On the other hand, the entire energy requirement of the system increases, as it moves not only more a door leaf, but two door leaves for an Öfmungs- or closing operation Need to become. Thus, this document could give no suggestion for finding the solution according to the invention.

Advantageous developments of the invention Rolltors are the subject of dependent claims 2 to 8.

In an advantageous development of the invention, the insert in the door leaf element at an angle of 2 ° to 30 ° degrees, preferably 5 ° to 15 ° degrees, be aligned obliquely to the door leaf level. As a result, a considerable stiffening of the door leaf element is achieved against deflection, which is particularly advantageous in the open position. In addition, the overlap of the deposits in the door leaf level can be produced with simple means.

Furthermore, two defensive strips can be arranged, which cover the gap between the deposits of adjacent Torblattelcmente on both sides in the closed state of the roller shutter. By a double-sided attachment of defense strips, that is an attachment of the defense strips, so that they are opposite each other over the gap between the deposits, the security of the roll-up door can be further increased. As a result, on the one hand prevented by the relative to the insert außcnliegende defense strips that a projectile or splinter can get into the gap. At the same time is prevented by the relative to the insert internal defense strips that even when overcoming the outer defense strip by a splinter, the splinter is stopped after passing the gap of the inner defense strip. Moreover, the bullet-resistant roll-up door can be operated at a speed of at least 0.5 m / s, preferably 1.5 m / s. This high-speed property means that the bullet-resistant door leaf can not only be used in safety-critical areas, but can also be used in industrial areas. In these areas, it is often desired that the door leaf can be opened and closed within a few seconds, since the operational processes should not be hindered. A fast opening and closing process is also safety-relevant in dangerous situations. Threatens an attack from the outside, the roller door must be closed after just a few seconds to resist ballistic attacks.

In addition, there may be a labyrinthine conclusion in the inventive roller shutter gate between facing end faces of two adjacent Torbelelcmente. Thus, the security of the door leaf can be increased at the interface between two adjacent Torblattelementen. For example, if projectiles are not perpendicular to the door leaf plane, but at an angle in which they can pass between two door leaf elements, they will be stopped by the labyrinthine termination. Similarly, it can be prevented that splinters or the like penetrate the door leaf, as these are deflected by the labyrinth-like conclusion and thus stopped before penetrating the Torblattebene. According to a further advantageous embodiment, the inventive

Rolling door to meet a Besehusshemmung according to DIN EN 1522: 1998 of at least the class FB3. The standard DIN EN 1522 classifies the bullet resistance of windows, doors and shutters. By adhering to a certain class, a desired debris can be achieved. The parameters that can be used to achieve the desired class include, among other things, the material used and the thickness of the insert used. A roll-up door class FB3 provides reliable protection against fire.

Furthermore, the insert and / or the at least one defense strip can be press-fitted into the door leaf element. By using a press fit additional holding and fastening elements for the deposit are obsolete. Since there are no additional elements to be provided, the weight of each door leaf element can be kept even lower. In addition, the insertion of the insert is kept so simple by the interference fit, that when changing the deposit, for example, to a higher protection class, no further tools are necessary. In a further development of the invention, the density of the material, preferably aluminum, of the Torblattelements may be less than the density of the material, preferably steel, the insert and / or the at least one Wehrstrei fens. By this combination of materials, the weight can be kept low despite the anti-ballistic property of the door leaf. Since the entire Torblattebene is covered by the overlap of the deposits with each other, it is sufficient if the insert has the anti-ballistic property. The remainder of the door leaf element does not have to meet this requirement and can therefore be configured as easily as possible, ie with a low density. Therefore, for example, the material of the door leaf member may be selected to have other properties such as high corrosion resistance.

According to another aspect of the invention according to claim 9, a door leaf element is provided for a bullet-resistant roller shutter. The door leaf element has a cavity in cross-section, in which an antiballistic insert is inserted, wherein the insert is plate-shaped and aligned in the cavity of the door leaf element obliquely to the vertical orientation of the door leaf element. The door leaf dement is characterized in that in the cavity of the door leaf element also at least one standing at an angle to the insert anti ballistic anti-Abregelstreifen is arranged.

Since the anti-ballistic property of the individual door leaf element is independent of constructive configurations of the entire roller door, the door leaf elements can also be retrofitted to existing roller doors. Such a door leaf element according to the invention represents a self-negotiable good.

In addition, with the door panel element according to the invention, the advantages explained above with reference to the roller shutter are equally achieved.

Advantageous developments of the door panel element according to the invention are the subject of the dependent claims 10 to 14. With the features shown herein, the already explained effects are equally achieved. The invention will be explained in more detail with reference to the figures of the drawings. It shows:

Fig. 8 is an illustration of a cavity of a Torblattelements according to a first

Execution form; and

9 is an illustration of a cavity of a Torblattelements according to a second embodiment.

In Fig. 1 is a perspective view of a roll-up door 1 is shown. The roller door 1 has a door leaf 2, which is guided vertically on both sides in the region of a frame 3 in guides 4. The door leaf 2 is driven by a drive 5 motor. Each guide 4 has a spiral section 41 and a vertical section 42. In the open position, the door leaf 2 in the region of a lintel in the spiral portion 41 is added as a winding, wherein the winding layers are present without contact to each other. In the closed position, the door leaf 2 closes the free passage space, that is, the area of the door opening, between the lateral guides 4 completely down to the ground and forms in this state, the Torblattebene.

The door leaf 2 is made of, serving as door leaf elements, lamellae 21, which are connected according to FIG. 2 against each other via hinge joints 22 bendable over lateral hinge bands 23. As a bottom-side conclusion of the door leaf 2 connects to the bottom lamella 21 of the door leaf 2, a graduation plate 24 which rests with a leading edge formed thereon in the closed position on the bottom side. in Fig. 2, a side section of the door leaf 2 is shown with blades 21. In a cavity 25 of the blade 21 an antiballistic insert 26 is inserted obliquely. The insert 26 is formed as a steel plate with a density of the steel of about 7.86 g / cm ³ , the steel plate having a thickness of 4 mm. The width and height of the steel plate depend on the size of the door leaf. The width in the exemplary embodiment is 3 m, wherein the height of the insert 26 is directly dependent on the height of the lamella 21 and here is 15 cm. The leading in the closing direction slat 21 is thereby overlapped by the trailing in the closing direction of the fin 21. As a result of this overlapping of adjacent lamellae 21, a labyrinthine overlap 27 forms as termination between the lamellae 21.

In addition, the arrangement of defense strips 30, 31 is shown in Fig. 2. As can be seen here, two defensive strips 30, 31 are inserted into each cavity 25 of a lamella 21. These abut the liner 26 such that a first backing strip 31 extends from the liner 26 to an interior, while the second backing strip 30 extends from the liner 26 to the exterior of the roll-up door 1. The defense strips 30, 31 thus extend angled to the Torblattebene. In this case, the defense strips 30, 31 as shown in Fig. 2 can be vertical, in a 90 ° Angle to the Torblattcbene extend or, as shown in Fig. 3, at an angle other than 90 °, that is inclined to the door leaf extend.

The each forming between two deposits 26 in the overlap region gap is, for example, so covered by two defense strips 30, 31, that no space between the insert 26 and the Abwelirstreifen 30, 31 through which a straight line from the outside of the roller shutter 1 inside of the roller shutter 1 can be pulled. There is thus no direct penetration of a projectile or a splitter through the roller door 1 possible.

In addition, the antiballistic insert 26 is designed in one piece. This ensures a bullet-resistant property even safer. By this design, no interfaces bridged or mounting points on the insert 26 must be additionally secured. The one-piece design thus not only increases safety; Simultaneously, the H first simplifies! ment process and the insertion of the insert 26 in the lamella 21st

The individual defense strips 30, 31 are integrally formed. These are formed approximately plate-shaped and have a length corresponding to the width of the door leaf 2, or corresponding to the insert 26. The thickness of the respective defense strips 30, 31 may differ from one another and from that of the insert 26. Alternatively, the insert 26 and the at least one Abwelirstreifen 30, 31 elements of the same material and the same thickness may be. Thus, the protective strips 30, 31 may be a steel plate with a density of the steel of about 7.86 g / cm ³ . In addition, the defense strips 30, 31 may have, for example, a thickness of 4 mm. The Abwelirstreifen 30, 31 have similar to the insert 26 anti-ballistic properties. The material of insert 26 and protective strips 30, 31 may be, for example, rolled steel. FIG. 7 shows a detailed view of a lamella 21 ^" according to the invention.

For ease of illustration, the defense strips 30, 31 are not shown in this illustration. In the slat 2 Γ 'from the side of the antiballistic insert 26 is inserted. Similarly, the backing strips 30, 31 can be slid laterally into a sipe 21 ^" , whereby the at least one defensive strip 30, 31 can be inserted individually or together with the insert 26. For instance, insert 26 and backing strips 30, 31 can be inserted into the sipe 21 "welded, glued or similar connected.

The insert 26 and the defense strips 30, 31 are integrally formed and are formed by forming, such as bending, deep drawing or pressing. Thus, between the insert 26 and the defense strips 30, 31 no edges must be formed, but may have a smooth transition. This can be made possible by a correspondingly flexible and bullet-resistant material of the insert 26 and protective strips 30, 31. For example, a metal with high bendability and / or high deformability can be used here. Depending on the application, the material of the insert 26 and defense strips 30, 31 can be varied. Conceivable here is an exchange of about only the at least one defense stripe 30, 31, or only the insert 26 while the insert 26 and the at least one defense stripe 30, 31 remains in the cavity 2. Furthermore, the insert 26 can be press-fitted into the slat 21 "at an upper position 28a and a lower position 28b, for which purpose a receiving pocket is formed in the slat 21" at an upper sixth in the closing direction and a sixth lower in the closing direction. In the upper and lower receiving pockets, the insert 26 extends substantially over the entire width of the lamella 21 ", that is, the lamella 21" is secured in an upper and lower region over 3 m in the receiving pocket. In addition, the insert 26 extends in height corresponding to the height of the lamella 21 ", so that the insert 26 extends substantially between the highest and lowest point in the closing direction of the cavity 25 of the lamella 21". Between the insert 26 and the side walls of the lamella 21 "parallel to the door leaf plane, an angle α is formed, which in the present exemplary embodiment amounts to 7 ° (a = 7 °) As can be seen here, the lamella 21, 2 Γ has a contour in which respective insertion areas for an inlay 26 or defense strips 30, 3 1 are formed are. By forming these insertion areas, the insert 26 and the defense strips 30, 31 can be easily accommodated in the cavity 25 in the respective position, so that tilting, shaking or slipping prevented and thus the safety of the roller door 1 is guaranteed.

In the event of a ballistic attack from the outside of the door leaf 2, it is to be expected that a projectile will penetrate the outwardly directed first surface of the lamella 21, 21 ^' , 21 "After penetrating this surface, the projectile will strike the insert 26. Since this insert 26 has an anti-ballistic property, the projectile can not penetrate this insert 26 and is deflected at this or remains stuck in the insert 26.

As a result of the simple design of the lamella 21, 2 Γ, 21 ", the damaged lamella 21, 2Γ, 21" can be released from the lateral hinge bands 23, to which the lamellas 21, 2Γ, 21 "are screwed in. Subsequently, a new lamella 21 , 2 Γ, 21 "can be inserted between two old lamellas 21, 2 Γ, 21".

Likewise, the antiballistic inserts 26 can be exchanged in all lamellas 21, 21 ", 21. Since the insert 26 has a plate-like shape, it is easy to manufacture and only has to be cut to the dimensions of the cavity 25 of the lamella 21, 2 Γ, 21" , By means of the press-fitting of the inserts 26 into the lamellae 21, 2Γ, 21 ", they can be taken out quickly and new inserts 26 inserted.Thus, the entire door leaf 2 can have different properties and be adapted to changing environments.

Does a projectile not perpendicular to the door leaf 2 or caused by the impact of Proj ectils on the lamella 21, 2 Γ, 21 "or the insert 26 splinters, so can by the labyrinthine overlap 27 and by the defense strips 30, 31 prevented be that they can get further to the inside of the door leaf 2. Thus, the overlap 27 of the lamellae 21, 2Γ, 21 "ensures that the door leaf 2 as a whole is ballistically resistant. In addition, deflected parts can be trapped by the labyrinthine overlap 27. The invention allows, in addition to the illustrated embodiment, further design approaches. The angle α between the lamella 21, 2 Γ, 21 "and the insert 26 can be between

2 ° and 30 ° degrees, more preferably between 5 ° and 15 ° degrees. Depending on the angle, the stiffening of the lamella 21, 2Γ, 21 "and thus its stability can be adjusted, while the weight of the individual lamella 21, 2Γ, 21" also changes depending on the angle. The angle is to be selected taking into account the dimension of a lamella 21, 2Γ, 21 ^" , the material used, the width of the door leaf 2 and the desired bullet-proofing effect, in the case where the door leaf 2 is deflected to the open state in a horizontal position is a bending moment acts on di e longitudinal sides of the lamella 21, 2Γ, 21 ^" . Due to the oblique arrangement of the insert 26, the moment of resistance of the entire lamella arrangement can be increased with respect to this bending moment. The moment of resistance of the lamellar arrangement increases with the angle a.

In addition, more defensive strips can be arranged in the cavity 25 of a lamella 21 so as to further increase the protection of the roll-up door 1. Also, instead of several defense strips 30, 31, only one defense strip 30, 31 may be arranged in a cavity 25. For example, only the backing strip 30 may be formed which extends relatively outwardly relative to the liner 26 and is disposed in an upper region of a liner 26. Here, the defense strip 30 is arranged so that the forming between the deposits 26 gap from below, that is seen in the direction of the opening direction of the roll-up door 1, is covered by the defense strip 30.

Also, instead of or in addition to the protective strip 30, the further protective strip 31 may be formed which is formed on the opposite side of the first protective strip 30 of the insert 26, that is, extending inwards. This defense strip 31 may be formed approximately in a lower region of the insert 26 be. Thus, this defense strip 31 covers the gap between the inserts 26 as viewed from above, that is, in the direction of the closing direction.

The defense strips 30, 31 may be perpendicular to the insert 26 in a further Ausiührungsform. In this case, the Abwehrstreif en 30, 31 form an angle deviating from 90 ° with the Torblattcbene. In addition, the defense strips 30, 31 may have a cutting edge, which lies in the installed state on the insert 26, which is formed obliquely to the plate plane of a defense strip 30, 31. Thus, the defense strips 30, 31 can complete the area with the insert 26, even if an angle deviating from 90 ° between insert 26 and defense strips 30, 31 is formed, that is, the defense strips 30, 31 are not perpendicular to the insert 26.

The lamellae 21, 2Γ, 21 "according to the invention are designed step-like, with at least one step, at the end leading in the closing direction Preferably the front surfaces of the lamellae 21, 2Γ, 21" extend stepwise in the closing direction from the inside to the outside in the closing direction ascending. However, it is also conceivable for these surfaces of the lamellae 21, 2 ", 21" to descend from the inner to the outer side in the closing direction A step is formed by two surfaces which are substantially parallel to one another and connected by a surface which is substantially perpendicular to them The lamella 21, 2Γ, 21 "may also be formed at the leading end in the closing direction with a plurality of stages. If two lamellas 21, 2 ", 21" are aligned adjacent to one another, the surface of the lamellae 21, 2 ", 21" leading in the closing direction runs along the negative step profile of the opposite surface of the lamella 21, 2Γ, 21 "following in the closing direction Step-like design can also be dispensed with.

It is also conceivable that the lamellae 21, 2Γ, 21 "do not overlap in an area of the joints 22 but also in an overlapping manner, and also the area of the overlap, that is to say the length in the closing direction of the area in which a lamella in the Torblattebene is above the other lamella, is arbitrary and can be between several millimeters to several centimeters. In a preferred embodiment, the roller shutter 1 is designed as a high-speed rolling shutter 1, which is operable at speeds of more than 0.5 m / s, preferably 1.5 m / s. Alternatively, the roller shutter 1 may also be formed as a slower-running roller shutter 1, which is movable at speeds of less than 0.5 m / s. For smaller sized roller doors 1, however, the achievable speed of movement can also be higher than 1.5 m / s and reach without about 2.5 m / s or more. In addition, the roller shutter 1 can be designed such that it closes in a dangerous situation with a higher speed than the operating speed reached in the normal case. For example, the closing speed is often set lower than the speed of the roller shutter door 1 for an opening operation for safety reasons. But if a dangerous situation, such as sensors, detected, the roller door 1 can also reach the opening speed or even taking advantage of the weight of the roller shutter 1 even higher speed.

As an alternative to labyrinth-like closures between the individual lamellae 21, 2Γ, 21 ", which are formed by one or more steps, further non-contacting terminations are possible, for example, the terminations between the lamellae 21, 2Γ, 2Γ can be shaped as having acute angles of Also, semi-circular cross-sectional shapes are possible at the opposite ends of the blades 21, 21 \ 2 'formed on one face of each blade as a protruding dome-like shape and correspondingly on the opposite face of the adjacent blade a half-round Recess forms.

In order to produce an antiballistic property of the roller shutter 1, the insert 26 and the at least one protective strip 30, 31 have antiballistic properties. In this case, the insert 26 and the at least one defense strip 30, 31 in addition to the class FB3 also all other classes of DIN EN 1522: 1998, such as the class FB2 or FB4 meet. In addition to the insert 26, however, the lamella 21, 2Γ, 21 "may also have their own antiballistic properties, for example if it is made of a steel.Therefore, the anti-ballistic properties of the lamella 21, 21, 21" themselves and the insert arranged therein 26 supplement. To one It can thus be sufficient if the insert fulfills a degree of fire protection according to FB2, if, in addition to the insert 26, the lamella 21, 2Γ, 21 "has such an antiballistic property that the roller door 1 as a whole has an anti-ballistic property Bullet resistance complied with FB3.

By means of the insert 26 and the at least one protective strip 30, 31, the roller shutter door 1 can be tested for different types of projectiles according to DIN EN 1523: 1998, according to DIN EN 1522: 1998, class FB3 or higher Reach class. In particular, this test will test various bullet points and bullet points at different distances. In this case, the bullet resistance with regard to the overlapping areas at different angles of impacting projectiles is checked.

The inserts 26 may be secured in the receiving pockets by means of a press fit in the lamellae 21, 2Γ, 21 ". In order to facilitate the replacement of the inserts 26, the inserts 26 may also be provided with a clearance fit in the lamellae 21, 2Γ , 2Γ "be arranged. Also, other support systems of the insert 26 are possible in the lamella 21, 2, 21 ", so that the inserts 26 can be fastened with screws or rivets in the lamella 21, 2Γ, 21". If no replacement of the inserts 26 is provided, the inserts 26 can also be fastened with the aid of non-releasable connections in the lamellae 21, 2Γ, 21 ", where a pressure forming at predetermined locations of the lamella 21, 2Γ, 21" is conceivable Gluing or welding the insert 26 into the lamella 21, 2 Γ, 21 ". In one embodiment of the invention, the lamella 21, 2Γ, 21" may be made

Be made of aluminum. But the lamella 21, 2 Γ, 21 "can also be made of any other, preferably corrosion-resistant and lightweight material.The lamellae 21, 2Γ, 21" extend from one side guide 4 to the other lateral guide 4, so that they Cover entire width of the door leaf 2, or the door opening. In one embodiment, the lamella 21, 2 Γ, 21 "is made of different materials The side of the lamella 21, 2 Γ, 21" facing the outside of the door leaf 2 is made of a corrosion-resistant material, such as stainless steel, while the inside of the door leaf 2 facing side of the blade 21, 2Γ, 21 "made of a lightweight material, such as aluminum.

Examples of materials of the antiballistic insert 26 are safety steels, such as the material SECURE 500 ®, or composite materials, such as carbon fiber reinforced plastics, Kevlar or CFK, such as the material Duroprotect 5000 ®. The material of the insert 26 may also be any other material with an antiballistic property. In addition, the materials of the inserts 26 need not be of the same material. For example, inserts 26 in the middle region of the door leaf 2 can be made of a material of a higher bullet-resistant class according to DIN EN 1522 and deposits 26 in the lower and upper region of the door leaf 2 belong to a lower class.

In addition, not all slats 21, 21 "inserts 26 must be inserted, for example, inserts 26 can be inserted only in the lower slats 21, 2", 21 ", which open in the closing direction, while the upper slats 21, 2 ', 21 "without inserts 26 are formed.

Further, the insert 26 as a whole need not be made of the same material. For example, the insert 26 may be formed in multiple layers of interconnected different materials, or divided into different areas and depending on the area of a different material and have other physical properties. For example, the roller door 1 can be installed in an area in which ballistic attacks are possible only from one direction. Thus, the material in the middle region of the insert 26 could have physical properties which are particularly resistant to perpendicular loads, whereas the lateral regions of the insert 26 are made of a material which is particularly resistant to stresses acting obliquely to the surface. In addition, a rubber profile may be provided in the labyrinthine overlap 27 between adjacent lamellae 21, 2Γ, 2Γ 'in order to make the overlap 27 dense in terms of moisture and temperatures.

In order to ensure a comprehensive protective effect of the bullet-resistant roller shutter 1, a frame 3 can be made to the door leaf 2 also of an antiballistic material, such as steel.

The gate shown in Fig. 1 is designed as a roller shutter 1. However, the door panel elements according to the invention are also applicable to other door arrangements and other orientations of Torblattebene, as well as door assemblies. Alternatively, the Torblattelemente can also be integrated individually in existing Torblattanordnungen or replaced with existing Torblattelementen.
