Description

"Blasting Technical Stewardship"

The invention is directed to a device for generating an explosive-technical DämämmungsSysteme kit, in particular for use on and / or in buildings, for the production of door, wall or ceiling openings.

A generic kit shows the DE 197 04 193 A or DE 20 2005 010 354 U of the Applicant.

Show the known solutions already a number of advantages, in particular they are expandable and relatively flexible and especially easy to transport, if they are not filled with an insulating material, such as water. Thus, the variations are limited in part due to the special design.

The present invention has set itself the goal of providing a very light, in particular a stackable system that can be adapted to any purpose, both in size and in the basic form.

With a device of the type described above, this object is achieved according to the invention by at least one blank of a fabric which is collapsible by means of Velcro to a hollow body, wherein at least a portion of the wall surfaces of the hollow body forming textile areas with receiving pockets for reinforcing sheets of plastic or Cardboard are provided, wherein a plurality of hollow bodies on a plate-shaped support member by means of Velcro fasteners next to each other and / or stacked, solved.

BESTÄTIGUNGSKOPte Due to the fact that the kit elements forming the hollow bodies can be folded from textile blanks, the system is very flexible, the provision of hook-and-loop fasteners for the connections of individual elements with one another or with the carrier element also has the advantage that practically any desired size can be assembled on site , If such systems are used, for example, in a police operation, they are extremely quiet even in their handling.

In the case of other systems not owned by the applicant, the hollow bodies generally consist of narrow plastic profiles, which entail a number of disadvantages which are avoided by the present invention:

Rigid, inflexible forms and frames are not conspiratorial, meaning that task forces in urban areas can disguise these resources only to a limited extent. When overcoming larger distances in the open area, especially if they have to be covered on foot, these frames can usually only ever be transported by one person and thus not particularly comfortable. In the case of air pollution, eg in helicopters, these bulky frames require appropriate space and must be specially secured / lashed. In the detonation caused by the plastic jacket such frame a significant fragmentation flight, which may endanger the emergency services at close range and cause various property damage. The non-stackable systems require an explosive amount "X" due to their mediocre damming weight (30 to 45 kg). This amount "X" limits the use in buildings, because depending on wall thicknesses explosive quantities would have to be used, which endanger the stability of the entire building. In addition to the above disadvantages, a further disadvantage is that the systems can not destroy floor slabs, which were produced, for example, in Central European construction due to their design and their lack of magnification or can blast into these holes.

Advantageous embodiments of the invention will become apparent from the dependent claims. It can be provided in particular that the hollow body with a film tube for receiving liquids, sand, plastic granules or the like. are equipped.

A further embodiment of the invention consists in that at least one side of the hollow body facing the surface to be blasted and / or of the carrier element is equipped or can be equipped with film explosive and / or detonating cords.

Depending on the purpose, it may be useful, e.g. the explosive elsewhere, e.g. to be positioned inside the digestion system. For this purpose, the invention provides that wall pockets of the individual hollow body can be equipped with foil explosives and / or detonating cords.

In a particular embodiment, it is provided according to the invention that the edge regions of the carrier element are provided with carrying handles and / or straps and / or Velcro straps. Thus, the device according to the invention can be designed as a backpack and thus can be easily carried by the people who want to perform a blast. Due to its shape and size it is very conspiratorial and therefore easy to camouflage. An additional transport protection is for example at a Air pollution not mandatory.

It is also advantageous that in the detonation no sharp-edged or hard splinters that could lead to injuries of the emergency forces occur.

Since the system is designed to be stackable, the weight of the detonation can be extended as required and enables, among other things. a reduction in the amount of explosives needed for the particular application. It is also a simple use inside buildings possible to perform a targeted, localized demolition can.

A further embodiment may consist in that at least two further Velcro straps are provided on the carrier element and / or in the respective hollow bodies in the position of use in the lower region.

If, for example, six individual elements are provided as hollow bodies, they can be positioned next to one another with support element or carrier cloth folded together, wherein the individual elements can be tensioned with the Velcro belt. By the two located in the lower area at least two other Velcro straps can be achieved that the load when lifting the system in a vertical position are evenly distributed over the rotating straps and are picked up on the handles. On the other hand, a positioning of the kit in the direction of tilting on a wall to ensure safe.

In order to change the position of the force applied to the insertion plates explosive in its distance relative to the surface to be sprung within the hollow body, the invention also provides that the film tube is formed as a tube in the hose, wherein at U-shaped Positioning of the double film tube in the hollow body in a U-leg between the film tubes a pair of stiffening plates can be inserted.

If, for example, the inner tube is filled with water, then it can only expand as far as the width of the stiffening plate pair permits, due to the stiffening plate pair inserted on the outside. If comparatively narrow plates are inserted, the inner tube can widen further than when relatively comparatively wide stiffening plates are inserted, so that in the latter part the explosive introduced between the U-legs is pressed closer to a wall of the hollow body than in the other case.

Further features, details and advantages of the invention will become apparent from the following description and from the drawing. This shows in

8 is a simplified representation of a simplified spatial assembly drawing of filled with explosives hollow bodies and hollow supporting bodies and in the

9 and 10 is a plan view of an open

Hollow body with internal liquid-filled double tube in two different positions.

The generally designated 1 kit for generating a technical Verdämmungssystemes is formed from a plurality of designated 2 in their use position rod-shaped hollow bodies, which are connected via a textile sheet-like support member 3, which is equipped with Velcro strips 4, together. The hollow bodies 2 are in turn made of a textile material, wherein double-walled inner surfaces are formed by sewing pockets 5 into the strips of plastic or cardboard, e.g. are insertable, e.g. Hollow web plates 6 to give the system a certain grip.

Since the hollow bodies 2 essentially consist of a textile material al are formed and also the hollow chamber web plates have a low weight, the kit 1 is easy to transport. For this purpose, the textile composite part or the carrier element 3 also has sewn-on straps 7 in order to be able to transport the entire package as a kind of backpack, in particular if the hollow bodies 2 are folded together with the unfilled tubes 14 into packets, so that several packets are added The entire package summarized by the support element can be wrapped.

If a different transport is desired, additional support loops 8 are provided, which may also be provided on the textile assembly surface, or else directly on some hollow bodies 2.

The assembly of the elements is indicated in Fig. 1 by arrows 9 and 10, the arrow 9 is to symbolize that the textile composition 3 via Velcro fasteners and Velcro 4, the hollow body 2 can assemble, while the arrow 10 indicates that after filling and accordingly Equipping the hollow body, these can be closed via an upper lid 11, which in turn is provided with Velcro closures.

Since all surfaces of the hollow body 2 have pockets 5, they can be equipped with web plates 6 or even, if this should be useful, with web plates 6 a, which are provided with, for example, film explosive 12. Instead of the foil explosive 12, explosive cords 13 can also be applied to corresponding plates 6b, as indicated in FIG. 4.

In Fig. 3a, a modified embodiment is shown. For example, three of the reinforcing elements which can be inserted in the wall pockets are missing there, where an im Substantially flexible hose forms, with a filled with eg water hose 14 is retracted. By extending a wall, it is possible to make the hose 14 longer to provide expansion spaces in the event that the elements can be folded into a package according to the arrows 20. The water in the hose 14 then has opportunities for evasion within this hose 14. After folding, for example, via Velcro fasteners 21, the package can be secured in the folded state.

If such a hollow body 2 is used, the excess length of this lid-like element IIa can be folded back into the position according to FIG. 3a. If it is then wound, whereby the water is pressed into the remaining hose 14, the hollow body 2 stiffens to the desired shape in the application.

For example, a chamber dividing wall 6a can be sewn so that it remains in place to ensure the defined hollow chambers.

In FIG. 4, it is further indicated that hoses 14 communicating with the hollow bodies 14, possibly double hoses, can be introduced, which can be filled, for example, with water or sand to produce damming elements, which is not shown in greater detail in the figures. The corresponding plates 6b with Sprengstofffschnüren or explosive films can, as indicated in Fig. 4, be positioned between the legs of the U-shaped introduced in the hollow body 2 tube 14, but in the same way this can also be done in an outer pocket, as shown in FIG 3 is indicated.

To form stiffening or support elements can the hollow body 2 also be equipped exclusively with hollow chamber web plates 6 both in their edge pockets as well as the formation of diagonal or transverse webs, as Fig. 5 shows, where there the hollow chamber web plates are partially cut off and shown in the not fully tightened state.

Fig. 6 shows a hollow chamber blank, e.g. consisting of a front side 15 forming wall portion, the two side walls forming the wall portions 16 with intermediate rear wall portion 17, in which also the upper and lower lid 11 is formed respectively. The textile bags are indicated by dash-dotted lines.

FIG. 7 shows, in a simplified representation, the textile component part 3 with its Velcro strips 4, which serve for looping and fixing the hollow bodies, where the straps 7 and carrying straps 8 and also Velcro straps 4 a are indicated.

Fig. 7a shows the folded-up to a backpack surface 3 after several packets of the hollow chamber blanks 2a are placed on the surface 3, which is indicated by dashed lines in Fig. 7.

Fig. 8 shows an application example of a kit according to the invention 1 in front of an indicated wall 18, which is to be blown up to allow access, for example, behind the wall of a person, for example by a cause of fire is included. In order to achieve a certain height of the kit, this kit is on the bottom of a package Ia of an assembled only with web plates assembly of hollow bodies 2a. The package 1a may also include a slide-in sleeve 20 for a rod or the like to position the package in a higher position in front of the wall. tioning.

In Figs. 9 and 10 it is still shown how the position of the explosive, e.g. a foil explosive 12, on a hollow chamber web plate 6 relative to a side wall of the hollow body 2 can change. For this purpose, the hose 14 is formed as a double hose or hose-in-hose system with an outer hose 14a and an inner hose 14b, wherein the partition wall between the two communicating pipes is formed by the hollow chamber web plate 6 with explosive 12, which is between the two U Leg of the double tube was positioned.

In order to position the explosive closer to the corresponding wall or further away from this, a pair of stiffening plates 19 a and 19 b of different width is positioned in the one U-leg between the two tubes 14 a and 14 b, such that the expansion of the Water to be filled inner tube 14b is limited accordingly. In the width "X" of the stiffening plates 19 shown in FIG. 9, a center position of the explosive within the hollow body 2 results approximately. This center position is designated "Y" in FIG. 9.

In Fig. 10, the stiffening plates 19b are significantly wider, which is represented by "X ¹ ", such that here in a U-leg of the double tube can not stretch so far, so that a much closer position of the explosive 12 (distance "Y '") results to the corresponding wall, which is then closest to the object to be blasted, for example.

It should be noted here that the expansion of the tubes and also the tube shape in plan view is only symbolically reproduced, whereby here a corresponding shape and content balance, since the double tube is positioned as a communicating tube within the hollow body 2.

Of course, the invention is not limited to the illustrated embodiments. Further embodiments are possible without departing from the basic idea. Thus, in particular, the hollow chamber web plate can be fixed fixed by sewing or the appealing bag, which is indicated by crosses in Fig. 9 and designated 22. In such a case, then, the hollow chamber / web plate is mounted in an element which is then sewn at the time.
