Abstract
The invention relates to a device (1) comprising at least one welding cam (2-2") for attaching ballistic protection elements (10) and additional add-on parts (11) to an object (5). In order to be able to attach a ballistic protection element (10) and an add-on part (11) to the same welding cam (2-2") with different torques, a welding cam (2-2") having a threaded bore (3) and an external thread (4) is proposed. In this case, the ballistic protection element (10) is screwed on with a first predefinable torque by means of a clamping nut (7; 7') which can be screwed onto the external thread (4) of the welding cam (2-2"). For this purpose, the clamping nut (7; 7') has a through-bore with an internal thread (8). Through this through-bore, the corresponding add-on part (11) can be connected to the threaded bore (3) of the welding cam (2-2"). Since the add-on part (11) bears against the clamping nut (7; 7') and not against the ballistic protection element (10), the add-on part (11) can be attached to the welding cam (2-2") with a second torque conforming to standards, without damaging the ballistic protection element (10).
Description
DESCRIPTION
Device for attaching ballistic protection elements The invention relates to a device for fastening ballistic protective elements and additional add-on parts to an object which is to be protected in particular from the effects of weapons or mines, said device comprising a welded stub which is fastenable to the object and the base region of which, facing the object, is connectable to the object via a welded connection, said welded stub also having a threaded bore into which a bolt is able to be screwed from the outside.
A fastening device of this type is known for example from the documents DE 20 2005 000 198 Ul and DE 10 2010 018 486 Al. A disadvantage in the use of these known devices has proved to be that when both a ballistic protective element and an add-on part are fastened to the same welded stub, these parts cannot be mounted independently of one another in time. Furthermore, when the known welded stub is used, it is not generally possible to screw the ballistic protective element and the additional add-on part to the welded stub - and thus to the object to be protected - with different torques.
Since, however, the protective elements have to be fastened with less torque than is prescribed for the add-on parts by corresponding standards, a standard screw-connection of the add-on parts to the welded stub is frequently not possible.
The invention is based on the object of specifying a device of the type mentioned at the beginning, in which a ballistic protective element and an add-on part are able to be fastened to the same welded stub with different torques.
Device for attaching ballistic protection elements The invention relates to a device for fastening ballistic protective elements and additional add-on parts to an object which is to be protected in particular from the effects of weapons or mines, said device comprising a welded stub which is fastenable to the object and the base region of which, facing the object, is connectable to the object via a welded connection, said welded stub also having a threaded bore into which a bolt is able to be screwed from the outside.
A fastening device of this type is known for example from the documents DE 20 2005 000 198 Ul and DE 10 2010 018 486 Al. A disadvantage in the use of these known devices has proved to be that when both a ballistic protective element and an add-on part are fastened to the same welded stub, these parts cannot be mounted independently of one another in time. Furthermore, when the known welded stub is used, it is not generally possible to screw the ballistic protective element and the additional add-on part to the welded stub - and thus to the object to be protected - with different torques.
Since, however, the protective elements have to be fastened with less torque than is prescribed for the add-on parts by corresponding standards, a standard screw-connection of the add-on parts to the welded stub is frequently not possible.
The invention is based on the object of specifying a device of the type mentioned at the beginning, in which a ballistic protective element and an add-on part are able to be fastened to the same welded stub with different torques.
- 2 -In some embodiments of the invention, there is provided a device for fastening ballistic protective elements and additional add-on parts to an object which is to be protected from the effects of weapons or mines, said device comprising a welding stub which is fastenable to the object to be protected and a base region of which, facing the object, is connectable to the object via a welded connection, said welding stub also having a threaded bore into which a bolt is able to be screwed from the outside, wherein the welding stub is provided with an external thread, in that the device comprises a clamping nut having a through-bore with an internal thread, said clamping nut being able to be screwed onto the welding stub, and wherein the clamping nut has, on its side facing away from the object to be protected, a flange, the size of which is selected such that, in the mounted state of the device, the respective ballistic protective element is fastenable in a force-fitting manner between the flange of the clamping nut and the object to be protected and the corresponding add-on part is fastenable in a force-fitting manner between the bolt head of the bolt and the flange of the clamping nut.
The invention is based essentially on the idea of using a welded stub having an internal and an external thread. In this case, the respective ballistic protective element is screwed on by means of a clamping nut that is able to be screwed onto the external thread of the welded stub with a first predefinable torque. To this end, the clamping nut has a through-bore with an internal thread. Through this through-bore, the respective add-on part can be connected to the internal thread of the welded stub. Since the add-on part rests on the clamping nut and not on the ballistic protective element, it can be fastened to the welded stub with a second, standard torque, without damaging the ballistic protective element.
A further advantage of the device according to the invention is that the ballistic protective elements and the add-on parts can be fastened to the object to be - 2a -protected independently of one another in time.
In order to fasten the welded stub to the object to be protected, the welded stub can have a circumferential chamfer on its base side, said chamfer being able to be welded to the object via a fillet weld. However, it is also possible to use a welded stub having a flange that protrudes on the base side, which is then able to be welded to the object either peripherally via a fillet weld or via a plug weld.
Furthermore, it has proven advantageous for a centering pin to be present on the underside of the welded stub,

- 3 - PCT/EP2015/057545 said centering pin fitting into a bore present on the object to be protected and thus predefining the exact position of the stub.
In order to transfer the tightening torque when the ballistic protective element is fastened, bores can be provided in the flange of the clamping nut (resulting for example in a two-hole nut or in a capstan nut), it being possible for an appropriate special tool to engage in said bores in order to turn the clamping nut.
However, provision can also be made, in order to transfer the tightening torques, for the flange of the clamping nut to be provided circumferentially with two opposite wrench flats.
Further details and advantages of the invention can be gathered from the following exemplary embodiments that are explained with reference to figures, in which:
Figure 1 shows the longitudinal section through a device according to the invention, which is arranged on the object to be protected and contains a welded stub and a clamping nut, having a ballistic protective element fastened to the object to be protected;
