Definitions

• the technical sector of the present invention is that of mechanical and electromechanical systems, and more particularly the application of these systems on armored combat and security vehicles.
• the present invention relates to a ballistic protection device applied to combat and security vehicles. Indeed, to cope with certain threats (hollow charge bombs, core-generating charges, kinetic projectiles) capable of penetrating large armor thicknesses, the only thickness of material
• this shielding can be of a different nature: passive composite shielding or reactive shielding. It can be in the form of plates or bricks which are fixed to the roof of the vehicle. However, the roof of a combat vehicle, and in particular the roof of its turret, accommodates a certain number of equipment the mere presence of which prevents or complicates the integration of these armorings.
• a first drawback in the protection technique currently used remains in the fact that the hatches allowing the crew access to the interior of the vehicle, are handled at the sole force of the crews. The increase in mass due to a shielding can prevent handling and lead to the adoption of costly and complex assistance devices for the opening and closing of said hatch.
• the object of the present invention is to provide a protection device making it possible to obviate the above-mentioned drawbacks.
• the subject of the invention is therefore a device for protecting the roof of an armored combat or security vehicle using at least one protective means, characterized in that it comprises a structure for receiving the means of protection, said structure being mounted articulated by rotation on a support integral with the roof to occupy an active protective position and a passive position in which it is separated.
• the receiving structure is articulated relative to the roof by means of a bracket fixed to said roof.
• the height of the bracket is provided so as to avoid any interference with the operational devices fixed to the roof of the vehicle.
• the rotation of the receiving structure is ensured manually and / or using a motorization means.
• the device comprises a means such as a spring, a counterweight, a gas under pressure, a battery, a capacity or an equivalent system for storing part of the energy necessary for the passage from the passive position to the position active.
• a means such as a spring, a counterweight, a gas under pressure, a battery, a capacity or an equivalent system for storing part of the energy necessary for the passage from the passive position to the position active.
• the transition from the active position to the passive position is carried out without any external energy supply to the system, and is obtained by the stored energy.
• the protection means is of the ballistic type and constituted, by at least one armor plate and may be in the form of shielding elements fixed to the receiving structure.
• the protection means consists of elements reducing the electromagnetic signature of the vehicle.
• the device is removably attached to said roof to be separated therefrom.
• the invention also relates to the application of the device to the protection of the openings of the vehicle, such as the access hatches, the GMP hoods or the maintenance hatches.
• FIG. 1 represents a front view of the protection device
• FIGS 2a and 2b show the protection device, in its version with a single plate, mounted on a tank turret
• Figure 3a shows a top view of the protection device, in the released position
• Figure 3b shows a view from above the protection device, in position above the areas to be protected
• FIGs 4a and 4b show front and side views of the protection device, in position above the areas to be protected.
• a first embodiment of the protection device 1 of the roof 20 of a vehicle not shown in a double plate version there is shown a first embodiment of the protection device 1 of the roof 20 of a vehicle not shown in a double plate version.
• the device consists of an articulated plate 7, constituting a receiving structure, on which are fixed shielding elements 2.
• the plate 7 is kept at a distance from the roof 20 to be protected by means of a bracket 3 fixed on this roof.
• a support 4 can be arranged between the plate and the roof to reinforce the maintenance in place the plate and neutralize any overhang.
• the movement of the plate carrying the shields is done by a rotation mechanism 5 which can be manual or motorized (for example by means of an electric motor).
• the tray is positioned above the crew access hatches (not visible in this figure), it is provided, for safety reasons, that the energy required by the release movement of the tray allowing access and possible opening of the hatches, either stored in a means provided for this purpose: spring, counterweight, gas under pressure, batteries, capacity, or any equivalent system.
• This energy storage means 6 is linked to the motorization system 5 actuating the plate on simple command from the crew.
• the plate can occupy an active protective position and a passive position in which it is spaced from the roof.
• the height of the bracket 3 is provided in such a way that it avoids any interference with the operational devices fixed on the roof of the vehicle, such as the sighting, observation, detection, electromagnetic protection, communication devices.
• the device 1 is fixed to the turret 10 of an armored combat or security vehicle by the bracket 3.
• the plate 7 In the protective position, the plate 7 is positioned above the hatch 11 in order to protect the occupants of the vehicle against an attack using a weapon with high piercing power.
• FIG. 3a is a top view of the roof 20 of a vehicle and illustrates the invention in a double tray version in the released position. In this position, the hatches 11 and 12 allowing access to the interior of the vehicle are accessible and maneuverable by the members of the crew.
• the system comprises two plates 8 and 9 joined by a connection structure 21. On these plates are fixed either by shielding elements or by plates of special materials reducing the radar or infrared signatures.
• Figures 3b, 4a and 4b show the device according to the previous Figure 3a, the plates being brought into the protective position by rotation as explained above. It is arranged so that the surface and the shape of the plates 8 and 9 are such that they make it possible to effectively cover the areas to be protected. The distance separating the trays from the roof must be sufficient for the crew to be able to actuate the aiming devices and the observation means, located at the level of the hatch 12, without being hampered by the trays.
• the device according to the invention can be produced according to several variants.
• the plate can be removably mounted on the stem.
• This embodiment makes it possible to remove the plate in order to intervene more effectively if necessary at the level of the roof.
• the stem can then be permanently fixed to the roof of the vehicle.
• Another variant would consist in providing as many protection devices as there are surface elements to be protected. This would make it possible to minimize the size of the trays as well as possible and provide additional protection where it is desired.
