Priority is claimed of German Patent Application No. DE202020101070U1, filed Feb. 27, 2020, and entitled “Protective Shield”, the disclosure of which is incorporated by reference herein in its entirety as if set forth at length.
The invention relates to a protective shield.
A protective shield of the type mentioned at the beginning is known from the document DE 20 2011 051 144 U1. This protective shield (called protective cover there) consists of an at least approximately rectangular base body, wherein a first connecting element is arranged at a first edge of the base body and a second connecting element is arranged at a second edge of the base body opposite the first edge. In this solution, said connecting elements are designed as suction cups. The above-mentioned requirement “at least approximately rectangular” means in this case, and also for the invention explained below, that the base body has four edges, two of which run parallel to one another in each case, although the transition from one edge to the other can, for example, be designed to be more or less rounded.
The invention is based on the task of improving a protective shield of the type mentioned above. In particular, the aim is to create a protective shield that can be used even more flexibly.
This task is solved with a protective shield comprising the features of claim 1.
Thus, according to the invention, it is provided that the first and second connecting elements are each formed as part of a positive connection system.
In other words, the protective shield according to the invention is thus characterized by the fact that an option has been created for connecting the base body to at least one further base body also provided with the connection system, which brings with it the advantage that, according to the invention, a rescue stretcher formed from a plurality of base bodies, for example, or also a particularly large and stable protective shield can be formed. The suction cups provided in the aforementioned prior art are unsuitable for this purpose.
Other advantageous further embodiments of the protective shield according to the invention are apparent from the dependent claims for protection.
The protective shield according to the invention, including its advantageous further embodiments according to the dependent patent claims, is explained in more detail below with reference to the graphic representation of a preferred embodiment.
It shows
The protective shield shown in
As mentioned above, the base body 1, which is preferably formed from a flexible material, in particular fabric, has a body side and an attack side. By body side is meant here that side of the protective shield which faces the body of the wearer of the protective shield when in use. The attack side faces away from the body of the wearer of the protective shield, but faces a possible attacker. As an option the flexible material on the attack side and/or on the body side can comprise a punch and/or bullet-resistant material, e.g., a textile or fabric, in particular comprising aramid fibers.
It is now essential for the protective shield according to the invention that the first and the second connecting elements 2.1, 2.2 are each formed as part of a positively acting connecting system 2.
It is further particularly preferred—initially considered in general terms—that the connecting system 2 is formed from at least one of a zipper fastener, a plug-in connector (for example in the form of a belt or strap buckle), a hook and loop fastener (e.g., the two complementary parts (moieties)), toggles, ribbons, and a snap fastener. The at least one of a zipper, a plug-in connector, a hook and loop fastener, toggles, ribbons, and snap fastener can be arranged on the body side and/or at least one of a zipper, a plug-in connector, a hook and loop fastener, toggles, ribbons, and snap fastener can be arranged on the attack side of the base body 1.
In the figures themselves, the “and” variant of the two aforementioned options is shown in each case, i.e. an embodiment example in which the connection system 2 exists twice, namely once as a zipper arranged on the body side and once as a connector arranged on the attack side. Thus, in the illustrated example, the first connecting elements 2.1 are a first zipper moiety 2.11 (e.g., tooth tape without slide) and a first pair of buckle moieties 2.12 (e.g., female) while the complementary second connecting elements 2.2 are a second zipper moiety 2.21 (e.g., tooth tape with slide) and a second pair of buckle moieties 2.22 (e.g., male).
Considered still somewhat more closely, it is particularly preferably provided in this connection for realizing an overlap of two basic bodies 1 that, when the connection system 2 is designed as a zipper, the first connection element 2.1 is arranged exactly at the first edge 1.1 and the second connection element 2.2 is arranged at a distance from the second edge 1.2, wherein the distance is preferably in the range of 1 cm to 20 cm, in particular in the range of 5 cm to 15 cm.
Furthermore, when the connection system 2 is designed as a connector, two connectors are arranged both on the first edge 1.1 and on the second edge 1.2, in each case in the region of the corners of the protective shield.
As can be readily seen from the figures, it is possible in this way to connect two or more protective shields (e.g., identical shields) to one another, on the one hand, via body-side zippers and, on the other hand, via attack-side connectors, in order to form in this way, for example, a particularly large protective surface or a rescue stretcher.
Particularly because of the latter option, lifting handles 3.1, 3.2 are thereby preferably arranged on the base body 1, wherein, viewed more closely, it is particularly preferably provided that a lifting handle 3.1 is arranged on a third edge 1.3 of the base body 1 and a further lifting handle 3.2 is arranged on a fourth edge 1.4 of the base body 1, which is opposite the third edge.
As can be seen from
Considered still somewhat more closely, it is particularly preferably provided in this connection that the carrying handles 4.1, 4.2 and the carrying straps 5.1, 5.2 are arranged on edges of an imaginary rectangle on the base body 1, which rectangle is preferably twisted between 30° and 60°, particularly preferably by 45°, with respect to the base body 1. Or in other words: the carrying handles 4.1, 4.2 and/or the carrying straps 5.1, 5.2 are preferably arranged at right angles to one another. In this regard, as can be seen from
Furthermore, it is particularly preferred that the support straps 5.1, 5.2—in the event that an attacker should pull or turn the protective shield with a great deal of force—are provided with preferably concealed predetermined breaking points. This provision has the advantage that the user of the protective shield can let go of it if necessary, which would not be the case if his arm were “trapped” behind a support band 5.1, 5.2.
As with the prior art mentioned at the beginning, it is also preferably provided in the case of the protective shield according to the invention that the base body 1 is provided with an inflatable stiffening device 6 for its stiffening as required, i.e. depending on the situation at the point of use, the user can decide, whether—without using the stiffening device 6—he would preferably like to use a relatively flexible protective shield with which, for example, he can also easily pass through narrow places, or whether he would preferably use a protective shield which, thanks to the stiffening device 6, is designed to be rigid like a board. More precisely, the protective shield, which can also serve as a splinter protection, is provided with an inflatable air chamber system, which, similar to an air mattress, stiffens the bullet-resistant blanket. The stiffening element or the air chamber system is preferably inflated by means of a compressed air cartridge or the like. Furthermore, it is ensured that the at least one stiffening element or the air chamber system is also designed to be puncture-resistant or bullet-resistant so that it does not lose its tensioning effect in the event of a hit.
For this purpose, it is furthermore particularly preferably provided that the stiffening device 6, which in particular also comprises (with respect to the base surface of the protective shield) gas channels on the edge side (not shown separately), has a gas cartridge 6.1, preferably a carbon dioxide cartridge, with a pulling element 6.2, preferably a rope or a chain, for triggering the stiffening (i.e. filling the gas channels). The gas cartridge 6.1 can be in fluid connection with the air chamber system for inflating the air chamber system as required. The air chamber system can be located between the attack side and the body side of the base body 1 in order to protect the air chamber system against puncture by means of the puncture and bullet-resistant material of the base body 1.
As again can be seen from
As can also be seen from
In addition to the aforementioned stiffening device 6, with reference to
To ensure that no gap remains between the two plate elements when the protective shield is in use, it is further particularly preferably provided that, in order to form an overlap region 7.3, each pocket 7.1, 7.2 is designed to be more than half as large as the base body 1 or its base area; that is to say, an overlapping insertion of the plate elements is provided, whereby the protective shield, provided that the stiffening device 6 has not been triggered, can still be used quite flexibly despite the plate elements, because it can be bent approximately centrally. Moreover, it is particularly preferred that the overlapping area 7.3 is designed to extend from the first edge 1.1 to the second edge 1.2 (i.e. from top to bottom when used as intended).
Furthermore, again with reference to
In addition, rubber bands 10 are preferably arranged at all four corner regions of the base body 1, under which the said eyelets 9, if they are not required in use, can be (at least partially) concealed.
With reference to
In order to be able to easily pack the protective shield again, for example after use, the stiffening element 6 can be provided with at least one drain valve 6.6. More than one gas channel 6.5 or more than one stiffening element 6 can also be provided. The stiffening element 6 can preferably have a chamber system (optionally with several chambers) distributed over the base body 1. In this way (after inflation) an overall stiff, wall-like protective shield results, which can be used in particular as a protective wall, but also, for example, as a rescue stretcher for transporting the injured, a swimming aid or even a life raft.
The protective shield can have one or more pockets 7.1, 7.2, preferably on the attack side of the base body 1, wherein each pocket 7.1 is designed for receiving plate (panel) elements 11. These plate elements 11 are preferably bullet-resistant and/or punch resistant. Each of the one or more pockets 7.1 can be closable, e.g. by means of a zipper, in order to keep the plate elements 11 in place.
