Description

FLOOR PLATE SYSTEM FOR ARMOURED VEHICLES

TECHNICAL FIELD

The invention relates to a floor plate system that enables a reduction in weight, that is made up of perforated aluminium plates, that can be adjusted in accordance with the seating configuration of the passengers, that provides protection against mines and improvised explosive devices for armoured vehicles.

STATE OF THE ART

In this day and age mines and improvised explosive devices and mines are the primary threats to armoured vehicles and the passengers within. It has become necessary for an efficient protection to be developed for armoured vehicles against these threats. To this end, several designs for stepping surfaces have been developed that provide protection for armoured vehicles from mines and improvised explosive devices. These stepping surfaces can be categorised in three groups according to the design approaches they embody: systems that are directly connected to the bottom floor of the body, floating floors, systems with an established protection level and floating floors that provide increased protection to certain areas.

In the state of the art, in systems that are directly connected to the bottom floor of the body, protection from explosions is achieved by way of the geometry of the brackets that attach the stepping surface to the body. As the stepping surfaces are directly connected to the floor of the body, the protection this provides is less than other systems. In systems that have an established protection level with a floating floor, which is another system that is used in the state of the art, as the stepping surface is not directly connected to the floor of the body, this provides better protection than systems that are directly connected to the floor of the body, but as these systems do not have modular structures, for an improvement to be made to the level of protection, the whole system needs to be changed.

In the state of the art, one of the most effective approaches to providing protection to the surfaces on which the passengers step, is the use of a floating floor system. In floating floor systems, the stepping surfaces are designed to not be in contact with the bottom plate of the body. This causes difficulties in designing light, durable and practical stepping surfaces.

In addition, in floating floor systems, dampening pads are used to mitigate the damage caused to the passengers by the high pressure at the moment of explosion. However, the use of these products has a high cost. For this reason, the use of dampening pads is not preferred in all stepping surfaces, instead, dampening pads are used in the areas in which the passengers extend their legs in a sitting position. The inner placement within the vehicle may be changed according to requirements; in some vehicles the passengers may be placed with their backs towards the side plates, with their feet placed towards the interior of the vehicle, towards the corridor, and in some vehicles the passengers may be placed at the front of the vehicle facing forwards, with their feet close to the body side plates. This situation has created the need for a design for a stepping surface that can easily be adapted to the placement of the dampening pads in the vehicle.

The utility model/patent application number TR2016/18050, with the heading "FLOATING FLOOR SYSTEM IN ARMOURED VEHICLES THAT ENABLES THE DAMPENING OF THE ENERGY CREATED BY A MINE" that was encountered during the course of technical research, is a floating floor system, that is comprised of floating floors, that provides armoured vehicles protection from mines, that concerns a dampening plate, that dampens the energy created by a mine in the vehicle, and a dampening component that dampens the energy created by a mine in the vehicle. As one can see, there is no development relating to the configuration of dampening components in accordance with changes in location within the vehicle.

As a result, a development has been made in floor plate systems in armoured vehicles and a need as arisen that requires new structures that will eliminate the problems mentioned above and that will provide solutions to the existing problems.

PURPOSE OF THE INVENTION

The present invention relates to a floor plate system for armoured vehicles that meets the requirements mentioned above, that eliminates all disadvantages and that provides additional advantages.

The main purpose of the invention is to provide the facility to adjust the position of the dampening pads in accordance with the different seating configurations of the passengers by way of the perforated holes on the floor plate, as well as significantly reducing the weight of the plate by way of the aforementioned perforated holes and creating an advantage regarding the total weight of the vehicle.

An additional purpose of the invention is to make the installation and maintenance of the floor plate practical by way of the design that brings together the components that form the surface floor plate protection system in a compact fashion, and to provide the required protection throughout the floor of the vehicle by conjoining the dampening pads in accordance with requirements. An additional purpose of the invention is to reduce the cost of the protection system in the floor of the vehicle with regard to the changeable nature of the placement within the vehicle, as well as providing an adjustable perforated floor plate that allows flexible placement.

The structural and characteristic properties of the invention, as well as all the advantages it provides may be fully comprehended by way of the figures given below and the detailed description that makes references to these figures. Therefore, assessment should be made by taking these figures and the detailed description into consideration.

DETAILED DESCRIPTION OF THE INVENTION

This detailed description provides descriptions of the preferred embodiments of the inventive floor plate system (B) to facilitate comprehension of the subject and is in no way limiting.

As seen in Figure 1, the mounting of the floor plate system (B) within the vehicle is carried out by way of mounting it on the body of the vehicle (A). Figure 3 illustrates the detailed frontal view of the floor plate system (B).

The floor plate system (B) essentially comprises;

• at least one perforated plate (1) that can be described as the main platform, that enables it to be mounted to the body of the vehicle (A), that allows for the positions of the components that are attached to the upper surface to be changed,

• at least one knurled floor plate (2) that as far as possible prevents feet from slipping, that is placed on the upper surface of the perforated plate (1),

• at least one connection component (4) that enables the mounting of components, that is placed on the upper and lower surface of the perforated plate (1), • at least one dampening pad (3) that as far as possible, mitigates the pressure effect that can result in injuries to the legs of the personnel, that is connected to the upper surface of the perforated plate (1),

• at least one connection piece (5) that is placed between the knurled floor plate (2) and the perforated plate (1),

• at least one tape (6) that is located between the dampening pad (3) and the floor of the body of the vehicle (A).

In one preferred embodiment of the invention, the floor plate system (B) also comprises a passage hole (7), that is located on the perforated plate (1), that enables the passage of equipment such as pipes and cables that need to pass under the vehicle floor. The width of the passage hole (7) is determined in accordance with the pipe or cable with the largest diameter that is to pass under the floor of the vehicle. Therefore, there is no need for additional procedures to be applied to the plates.

In order to achieve the main purpose of the invention, a perforated plate (1) has been used. The perforated plate (1) has multiple holes at equal distance to each other and of equal size, and the plate is mounted on the body of the vehicle (A), on the upper surface of the floor of the vehicle.

The double sided tape (6) that is placed on the upper surface of the perforated plate (1) ensures that the dampening pad (3) is adhered to both the perforated plate (1) and the body of the vehicle (A). Dampening pads are placed on the perforated plate (1), in areas where the feet of the passenger will be placed when in a sitting position, and due to the tape, they can be repeatedly removed and reattached. The stepping surfaces of the dampening pads (3) prevent slipping. The mounting of the knurled floor plate (2) to the perforated plate (1) on the floor of the vehicle is carried out initially by passing and fastening the connection components (4) and connection pieces (5) through the holes on the perforated plate (1), and then by connecting the knurled floor plate to the connection components (4) and the connection pieces (5). The connection piece (5), ensures that the knurled floor plate (2) and the dampening pad (3), that are placed on the floor of the body of the vehicle (A) and the perforated plate (1), are at the same height, and therefore, ensures that the floor of the body of the vehicle (A) is level. The area and the hole on the perforated plate (1) on which the connection piece (5) is to placed can be selected, and the knurled floor plate (2) can be mounted in the desired area by way of the connection piece (5) that is placed in different holes. As a result of the change in the location of the knurled floor plate (2), dampening pads (3) can be mounted to the area that is created by way of the tape (6).

In one preferred embodiment of the invention, the dampening pads (3) and the knurled floor plates (2) have been sized to cover the same surface area. Therefore, any dampening pad (3) and knurled floor plate (2) can be relocated by attaching them to different holes on the perforated plate (1) in accordance with requirements. As long as the width of the body of the vehicle (A) does not change, even if the sizes of the dampening pads (3) and the knurled floor plates (2) change, due to the holes that are distributed at equal distances all over the perforated plate (1), the platform can continue to serve its purpose.

In one preferred embodiment of the invention, the perforated plate (1) has a hollowed structure that is similar to a tray. The depth of the hollow is adjusted in accordance with the height of the dampening pads (3). The need has arisen for the knurled floor plates (2) to be mounted on areas of the hollow of the perforated plate (1) where there are no dampening pads (3). In one preferred embodiment of the invention, the aforementioned perforated plate (1) has been manufactured out of aluminium. The fact the perforated plate (1) is manufactured out of aluminium significantly reduced the weight of the plate (1) and creates an advantage with regard to the total weight of the vehicle.

Finally, in one preferred embodiment of the invention, the aforementioned connection pieces (5) are bolts, washers, distance rings or rubber gaskets.
