Description

Roll-out security system

The invention relates to a roll-out safety system according to the preamble of claim 1.

In a generic portable barrier system according to the document US-2007/0176158 a cylindrical housing is provided, in which a roll-up receiving hollow shaft is rotatably mounted, said hollow shaft can be rotated by a hand-operated crank in one or the other direction. In addition, the hollow shaft for the purpose of locking a ratchet wheel associated with a

externally adjustable pawl cooperates. This barrier system is suitable for shutting off places that are dangerous for children.

The present invention was the object of the present invention to provide a system by means of which a mobile or stationary barrier over shorter or longer distances with a high stability and easy and quick assembly or disassembly is possible.

The object is inventively achieved in that the network is designed as a braid articulated and thus zusammenrollbar, wherein it is generated from a plurality of helically bent wires, ropes and / or strands of preferably high-strength steel, wherein the helically bent wires, ropes and / or strands are aligned perpendicular to the withdrawal direction of the network, so that the net can be rolled up on the vertically standing wave.

With this inventive design of the retractable and rollable security system on the one hand a high stability of the same ensured so that it withstands vandalism, acts of violence and external environmental influences (eg wind, rain, snow, sandstorm, etc.) safely and also that does not solve the protection system, where a large number of people have to be carried through in a large density. Moreover, even such a network can not or only with difficulty be overcome or crawled through because the net can be pretensioned accordingly.

In addition, it can be easily and quickly assembled or disassembled without much prior knowledge, so that it can be quickly set up, for example, for a temporary barrier, for example at a stadium and then removed during the sports event again, so that the spectators can leave the stadium unhindered after the end of the game to avoid backwater.

Embodiments of the invention and further advantages and applications thereof are explained in more detail below with reference to the drawing. It shows:

1 shows a view of an inventive rolled-up network system,

2 is an enlarged partial view of a support of the network system of Figure 1,

3 is an enlarged partial view of the upper part of a box with rolled net and longitudinal element of the system according to Fig.1, and

4 is an enlarged partial view of an end support of a network system.

Fig. 1 shows a rolled-up network system 10 in the mounted state, which is suitable for various applications. For example, it can be set up at a football stadium, marking off various sectors in front of the entrance to the stadium, thus making it easier for spectators to enter, and also to ensure safety precautions to keep fans separated from each other in front of the stadium. Before the spectators leave the stadium again, these nets 11 can be rolled back into the box 15 within a few minutes without much effort and the system 10 can be dismantled, so that the spectators in the sequence can leave the stadium without backwater and comfortably.

Such systems are suitable for various applications, such as for large events in the sports as well as in other areas, but also on construction sites or roads could such Netz- Systems can be used as mobile or just as stationary barriers or guides.

Such a network system 10 comprises a box 15, in which a device not shown in detail is included with a rotatable shaft on which the network 11 is switched on or rolled out. In the unrolled state - as illustrated - the net 11 is conveniently held on the one hand in the box 15 in this shaft and on the other hand on an end support (see Figure 4) and in between a plurality of spaced-apart supports 12.

In addition, at least one longitudinal member 16 is guided on the top of the network, starting from the box 15 to the end support. Both this longitudinal element 16 and the net 11 are tensioned after fixing to the end support by means of a clamping device not shown in detail, so that the suspended from this longitudinal element network is additionally stabilized.

According to the invention, the net 11 is designed as a braid articulated and thus rollable, wherein it is generated from a plurality of helically bent wires 13, ropes and / or strands. The helically bent wires 13, ropes and / or strands are aligned perpendicular to the pull-out of the network, so that the network 11 can be rolled up on the vertical shaft. The wires, ropes and / or strands are made of a high-strength steel with a minimum tensile strength of 1 ¹ 000 N / mm ² .

In the present embodiment, the net 11 is braided from wires 13 of high-strength steel having a diameter of 2 mm and a tensile strength of 1700 N / mm ² . As a result, these networks can on the one hand be made very lightweight and on the other hand, they meet the stability requirements due to the high strengths in ideal Wise. This lightweight construction of the net allows for a long extendability of up to 50 m, without it being prone to sagging.

The box 15 is designed such that it is preferably transportable with a lift truck. Therefore, corresponding openings 17 are present on its underside, in which the forks of the lift truck can enter. The box 15 also has a door 16, through which access to the shaft and the Verspanneinrichtungen is ensured, and it is dimensioned so that in it the entire necessary utensils are enclosed, in particular the supports 12th

This results in a further advantage within the scope of the invention, namely, in this system, in the disassembled state, only this box 15 put down or be driven away and therefore very little space is needed with it.

Laterally adjacent to the door 16, a passage slot 18 extends approximately over the entire height of the box 15, through which the network 11 is passed. In addition, an opening 19 is provided above this passage slot 18, from which the longitudinal element 16 protrudes. Further, at the bottom of the box 15 a heavy material, preferably concrete, included, so this box also has a sufficient stability in the unrolled state of the network 11.

According to FIGS. 1 and 2, the supports 12 are each provided at the upper end with a protective hook 12 'and a centering means 16' for holding the longitudinal element 16. In addition, 32 are attached to these claws, which serve as additional support of the network 11. For this purpose, the net 11 can be hung with the threaded through this edge 32 and the ends of the wires 13 at these claws 32. The ends of the wires 13 are otherwise connected by formed loops 13 'with the adjacent wires. According to Figures 1 and Figure 3 are at the upper end of the network 11 at certain intervals fixed carriages advantageously present with brackets 21, which are each U-shaped and with a leg 21 'attached to the network 11. In addition, these brackets 21 are assigned as guide rollers 22 provided sliding elements which roll on the extended longitudinal member 16 when the net is pulled out. These brackets 21 are advantageously fastened to the net at such intervals that, when the net is rolled out, as can be seen in FIG. 1, they are located approximately at half the distance between the supports 12.

These brackets 21 on the net and the upstanding at the upper end of the supports 12 hooks 12 'with the centering means 16' are arranged so that a respective bracket 21 with the guide roller 22 on the longitudinal member through these hooks 12 'contactlessly and thus freely moved therethrough can, so that the network 11 is easy and without stopping ausrollbar.

4 illustrates the upper part of an end support 25 to which the end of the longitudinal element 16 and the end of the net 11 are fixed. This end support 25 may further comprise, in a mobile embodiment, a pedestal provided with a heavy weight, for example a concrete slab. The end of the net 11 is in this case equipped with a terminal strip 26, which has connecting elements 27 which are latched into corresponding slots 28 on the net facing side of the end support 25. At the upper end of this end strip 26, a bracket 29 is also provided with a guide roller. This bracket 29 is performed for the rolling of the network to the end support on the longitudinal element and thus the end bar can be moved to the net on it. Thereafter, this bracket 29 but taken away again from the longitudinal member 16. When assembling the system, first the box 15 is advantageously brought to the desired position with a lift truck or with any available means of transport. First, then the end support 25 and possibly the supports 12 are set up at predetermined intervals to each other, either they are inserted into holes in the ground or simply set up. Afterwards, the longitudinal element 16 can be pulled out of the box 15 through the opening 19, fixed to the end support and clamped in the box 15 by means of a bracing device. Once this longitudinal element is mounted, next the net 11 can be rolled out of the box 15 and pulled by hanging his brackets 21, 26 at the longitudinal member 16 to the end support 25 like a curtain and attached thereto. In addition, the network is stretched back by a bracing and advantageously hooked at the bottom and top of these claws 32 on the supports 12, so that sufficient rigidity is achieved that, for example, when a person hangs on the net or falls into this, the network only slightly and rather remains stable.

The invention is sufficiently demonstrated with the embodiments explained above. However, they still present themselves in other variants. So the box could be provided instead of a rectangular with a round or similar cross-section. Depending on the need, two or more boxes could be placed side by side. The end support could also be attached to a wall or the like.

The safety system is preferably provided with a fence-like braid, with a receiving box or a box-like device in which a device is provided with a rotatable shaft on which this Zaungeflecht, roll or rollable that none, one or more supports spaced from the box at certain intervals can be set up, and that at least one retractable from the box and durable in the established supports longitudinal element, preferably a rope is provided, on which the net is rolled out and held on support elements like a curtain.

These roll-out security elements can be used upright or lying or hanging. There are also oblique or other types of inserts possible. In addition, the shape of the rolled-up security element can vary in itself and be constructed differently over the rolled-up length.

In addition, these roll-up security elements can also be multi-layered and / or formed as a so-called sandwich structure, without the Roilbarkeit is restricted.

Other applications include mobile fence barriers at trade shows or similar occasions where it is necessary to flexibly access or even shut off different areas for different occasions.

In addition to the actual Absperrzweck but the present Rollzaunsystem can also serve other uses. For example, various other rollable materials can be rolled up in the box and rolled off and rolled up analogously to the fence weave. These uses can be used in the advertising sector. Accordingly, advertising posters can be set up and dismantled again. Due to its high stability against, for example, wind loads, the present application is also suitable for large events, sports events, trade fair services and personal control applications.

When using especially strong nets or braids, dynamic protection applications are also possible. For example, mobile protective devices can be used as temporary drive-through barriers. the. Similar uses are also possible for rockfall protection nets or to protect against other natural hazards.

When using, for example, high-strength fencing systems, the advantage that these special nets and nets can hardly be severed or severely severed with normal tools is still further exploitable. This provides increased breakthrough protection, which is often required for police and military applications. In addition, such protective applications may also be used in the area of sensitive objects (for example messages, transport devices, energy supply systems, etc.) or in the field of personal protection.

If these boxes are equipped with a rollable protective fence against shaped charge weapons, then a mobile protection against corresponding threats can be ensured by, for example, RPG 7 and similar missiles. This use can be used in the area of military camps, facilities as well as in crisis and war zones. It has the advantage that efficient protection against such shaped charge projectiles can be achieved in a relatively simple and quickly installable manner. Ballistic protection can also be achieved by means of rollable elements in the case of canopies and overvoltage of installations worthy of protection.

Likewise, rollable splinter protection walls for temporary applications can be easily transported, assembled and disassembled. Instead of the braid for this purpose a splinter protection system is mounted in the box, which can also be rolled out and built analog. Also possible are combinations of network systems with splinter protection elements, which can be rolled together or assembled one after the other. Such splinter protection applications against improvised explosive charges are used in particular in crisis areas, where in addition to military especially civilian facilities and persons (eg VIP persons) must be protected. Thanks to the rapid installation, temporary protection functions can be performed efficiently and cost-effectively.

The rolling box system described can also be combined with heat-resistant protective elements, which are used especially in military installations and equipment against infrared images and films. These often textile or textile-like elements can also be rolled up and stowed in the manner described.

In addition to the upright, ie vertical embodiment variant, horizontal, suspended or oblique uses of the aforementioned applications are also possible. For this purpose, the boxes are designed so that the roll-out elements and / or fencing systems can be pulled out horizontally. This is used for cover purposes and roofing of protected facilities and infrastructures. Here too, the strong design and the possibility of biasing the rollable elements is also a great advantage in practical application because wind, rain and snow loads, as well as other external influences (e.g., sandstorms) can have significant load bearing on the support system. Preferably, such recumbent or hanging applications with double-sided longitudinal members (e.g., tethers) are used to unwind and unwind. This also simplifies assembly and disassembly.

With the mentioned boxes is basically meant a closed, substantially cylindrical body, wherein the net system can be rolled up. Depending on the intended use, however, these boxes can also be designed to be open, in a dissolved structure or at least partially closed; of course, combinations of these embodiments of the boxes are also possible.
