Definitions

• the invention relates to a protective shield for police forces according to the preamble of claim 1.
• the three main components of the known Protective shield namely the actual shield, an in approximately shamrock-shaped shield stiffening element as well as the form-fitting support and holding elements are all made of polycarbonate and in pairs connected by rivets.
• the actual shield itself is deformed on all sides and towards the central zone of the shield convex.
• the shamrock-shaped shield stiffening element lies on the inside of the shield, i.e. the side, which faces the user, one rivet each connects the sign to one of the leaves of the shamrock.
• the form-fitting support and holding elements are like the sign, one-piece made of polycarbonate, vacuum-drawn, the inside of the support and holding elements itself intersecting half-shell-shaped depressions for the user and its outside is one of the inside of the shield has the corresponding contour.
• the attachment of the Adapted support and holding elements take place outside of the shield stiffening element, namely on the one hand on the lateral edge deformations, on the other hand on several dots distributed over the sign.
• For arm rings and handles have the half-shell-shaped curvatures on their recesses adapted to maximum surveys.
• a protective shield for police forces are in the technical guidelines for protective shields fixed. This includes a maximum weight of 3.5 kg, a holder for the forearm, when overloaded the arm releases, the dimensions of the protective shield, a portion 65% of the shield surface made of transparent material etc. Also the requirements for puncture resistance, temperature and Chemical behavior, elasticity and the type of Puncture resistance tests are in the technical guidelines fixed.
• the known protective shields have many of the specified ones Requirements met, but it turned out that local weaknesses in puncture resistance occur. Because of the inherent rigidity of the protective shield namely almost the full impact force of the stabbing weapons or Endure plug gauges.
• the invention is based on the aforementioned state of the Technology based the task, with a protective shield, under Compliance with those specified in the technical guidelines Requirements, especially without increasing the weight, improve the puncture resistance.
• the inventors have recognized that it is important a secure "arm attachment” with high edge flexibility of the to combine the actual shield and in the central Zone the rigidity with a puncture-resistant surface to increase significantly.
• Under secure "arm attachment” is protection on the one hand, on the other hand one as rigid as possible attachment for the support and holding elements to understand.
• the solution according to the invention exists at its core, therefore, in the central zone of the protective shield to protect by an outer puncture-resistant layer, this Position at the same time for fastening the holding parts and if necessary the support elements is also used.
• the Invention provides for an additional sign on the outside of the sign, especially made of metal.
• a stab weapon the in an attack against the user of the Protective shield, either meets the additional shield on and becomes blunt on it, or it slides on the more flexible edge zones.
• the shape-matched support element a hard foam or rubber layer, one of which Page the elevations for a form-fitting support of the forearm and the other side, so to speak Mounting side with the sign, almost flat or even is executed.
• the flat side of the support is preferred with a thin, cruciform plate, connected directly, for example by gluing. This plate then forms the shield stiffening element and the mounting surface for the support elements.
• the condition becomes a protective shield in sandwich construction created that corresponds to the technical guidelines and, because of the additional sign on the outside of the sign, the puncture resistance increases.
• shield shield, shield stiffening element and additional shield
• additional shield Since the main components (shield, shield stiffening element and additional shield) are essentially flat, can the more expensive vacuum deep drawing can be dispensed with.
• the height of the mounted protective shield is lower than at the known protective shields, so that transport and Storage of the protective shields according to the invention protective shields mentioned above is improved.
• the additional shield as well as the shield stiffening element are preferably made of metal, in particular Made of aluminum.
• Fig. 1A shows a section through a generally designated 10 Protective shield.
• the actual shield 1 preferably has a rectangular basic form with the police / technical Dimensions of 950 x 550 in accordance with guidelines mm.
• additional shield 2 shield 1 and in the shield stiffening element 3 to each other in the assembled state aligned holes 5, 6, 7 are provided.
• the additional shield extends 2 and the shield stiffening element 3 does not have the entire area of the shield 1; rather the additional sign takes 2, as can also be seen from FIG. 2, essentially the area of the central zone of the protective shield 10.
• the Shield stiffening element 3 is in the embodiment shown (see Fig. 3) one cut as a right-angled cross Light metal plate, especially aluminum.
• the inside 3 'of the shield stiffening element is on suitable way, for example by gluing, with the support element 8 connected for the forearm.
• This is the support element on its outside 8 '' flat or even while the inside 8 'of the support element a concave half-shell-shaped curvature 9 to support the Has forearm.
• the curvature is from a bangle 11 attacked.
• One end of the bangle has an angled one Fastening bridge 21. This is with further blind rivets 22, the holes 23 and 24 pass through, force and positively connected to the additional shield 2 and the shield 1; the other end of the bangle is free so that the inserted arm is released in the event of an overload.
• FIG. 1B shows a section through the protective shield 10 in a plane parallel to the sectional view of FIG. 1A, however, here is not the bangle but the handle 13 to see.
• the sandwich construction of additional plate 2, actual shield 1 and shield stiffener 3 corresponds that of FIG. 1A.
• the handle 13, preferably made of plastic or light metal, has an approximately C-shaped Contour and, like the armlet, overlaps the half-shell Curvature of the support element 8.
• the end faces of the handle 13 are on the inside of the shield and are non-positive and positive by means of connecting screws 15 on the additional shield 2 through the actual shield 1 attached.
• the form fit can be done by brass sleeves 16, which in the associated, then correspondingly larger trained bores 17, 18 of additional shield 2 or Shield 1 are used, are increased. Prevent at the same time the brass sleeves 16 damage the inner surfaces the holes 17, 18, so that in particular the shield 1 selectively by the holding forces acting on the handle 13 is not so heavily loaded.
• Additional sign 2 is located (in this illustration) from below against plate 1.
• the Shield stiffening element 3 is made of a right-angled cross plate-shaped material shaped, e.g. B as cutting or Stamped part, and lies flat on the inside of the shield.
• the Contour of the additional shield 2 is selected such that the Connecting screws for the handles 13 and the arm clips 11 reach through the shield 1 and the additional shield 2.
• the exemplary embodiment shown has the support element 8 roughly the same layout as the shield stiffener 3 and there are two bracelets 11 and handles 13 provided, as detailed in DE 31 42 635 is known.
• brackets 19A and 19B are also Shot of a truncheon can be seen, the optional on both sides using connecting screws on plate 1 near the angled lateral edge surfaces 20 of the shield 1 attached could be.
• the angle W between the angled lateral edge surfaces 20 and the protective shield 1 is under Taking into account the technical guidelines mentioned above selectable and here 30 °.
• the protective shield can, for example, consist of a shield 1 clear, 3 mm thick polycarbonate, an additional label made of 1.2 mm thick aluminum and a shield stiffening element 3 made of 1.0 mm aluminum.
• the blind rivets should also be used to reduce weight and the handle are made of aluminum, the latter how the bangle can also be made of plastic.
• the Armrest is preferably a PU foam or cellular rubber used, the minimum thickness is about 20 mm and which increases in the edge areas up to about 40 mm.
• Protective shield an adaptation to changed Requirements in the simplest possible way.
• the additional sign can optionally be strengthened in order to Increase puncture resistance in the central zone.
• the diagonal extension of the shield stiffening element can be extended to the rigidity of the protective shield in to increase the edge areas, or it can be the thickness of the actual shield can be increased or decreased.
