Abstract
Description
- The invention refers to an improved flexible protection structure incorporating substantial innovations and advantages.
- In other terms, the invention provides the development of a flexible protection structure which may be used for the manufacture of any type of protection panel for terrestrial, naval and, aerial vehicles or for protection clothes for personal use against impacts of bullet, fragments of explosions, blade arms, etc. bringing a higher flexibility degree and keeping the same protection characteristics for the user as those known in the state of the art.
- Nowadays the structures permitting protection against impacts of projectiles from long barrel arms, short barrel arms, as possibly bullets, fragments of explosions, blade arms, etc. are already well known.
- However, the protection structures in use at present are rigid structures or structures with low flexibility, having besides a relatively high weight which difficults the transport of the structure and the adaptation of the user to the environment in case of personal protections. These kinds of protections are not capable to support various impacts on a reduced surface, specially at low temperatures.
- The applicant is the owner of a utility model describing a protection structure to solve the above stated problems, which characteristics are defined in the preamble of
claim 1. - The present invention has been developed with the object to provide a very flexible protection structure to solve the above mentioned drawbacks, moreover contributing at the same time other additional advantages which will be evident from the annexed description.
- Therefore, it is an object of the invention to provide an improved, very flexible protection structure, particularly for the manufacture of protection panels for terrestrial, naval and aerial vehicles or protection clothes for personal use against impacts from bullets, fragments of explosions, blade arms or similar of the type comprising: a first block having a first external layer to receive an impact on the structure, a second layer arranged in the interior part of the external layer and formed by a plurality of ceramic parts united together and a third more internal layer made of a ballistic material which serves as support for the second layer and that together with the first layer permits a lower fragmentation of said plurality of ceramic parts, and a second block appropriate to retain the impact element and to prevent the penetration of the same, embodying a plurality of ballistic material laminates. Particularly, the structure is characterised in that each of the laminates of the second block is coated on its front and rear surfaces with a layer of flexible plastic, gliding material.
- Said laminates may be made out as well from a ballistic material which has received in both of its surfaces a flexible water proof and gliding material by means of an immersion bath or by an application by pistol painting, atomization or similar.
- Thanks to these characteristics, a smooth gliding is possible between the laminates forming part of the second block, so that it contributes a higher degree of flexibility in respect to the structures known in the state of the art. In this way, the protection structure is adapted to the form of the body in the case of a personal protection device, this latter being arranged to improves the manoeuvrability of the user wearing such structure, being only necessary to apply a slight pressure between the two opposed borders of the structure, of an approximated amount of 2-3 kilograms to provoke the bending until the opposed borders come together.
- Preferably, the flexible, plastic and gliding material which has been mentioned is formed by a film of polyethylene in a first case or by a synthetic resin in a second case, also flexible and gliding.
- In a specially preferred embodiment of the invention it is foreseen to arrange a layer of an elastic adhesive material between the first external layer and the second layer forming part of the first block and another layer of elastic adhesive material located between the second layer and the third layer forming part of the first block.
- This described structure has as well the advantage that when receiving an impact in the front surface of the same, it turns rigid and hinders that the structure may bend towards the interior, so that it contributes a higher resistance in the sense of the impact and the direction of the projectile.
- With the characteristics and assembly of this structure, it permits to receive multiple impacts, such as 5 or 6 impacts on a surface of 700 cm2, at an ambient temperature comprised between -25ºC and 60ºC.
- Other characteristics and advantages of the protection structure which is the object of the present invention will be evident from the description of a preferred, but non limitative embodiment which will be shown as a non limitative example in the annexed drawings, in which:
-
-
Figure 1 . - It shows a diagrammatic view of a cross section of a portion of the protection structure according to the present invention; and -
Figure 2 . - It shows a diagrammatic front view of the layer for deformation, fragmentation and deviation of the path of the projectile or menace, provided on the ceramic parts. - According to the annexed figures of drawings, an embodiment is shown of an improved flexible protection structure aimed at the manufacture of protection panels for terrestrial, naval and aerial vehicles or protection clothes for personal use against impacts of bullets, fragments of explosions, blade weapons or similar which adopts the configuration of multiple layers as to be derived from the next description.
- Said structure comprises a first block (A) having a first external layer (1) to receive the impacts directed to the structure, a second layer (2) arranged in the interior in respect to the first external layer, formed by a plurality of ceramic parts bound together and a third more internally arranged layer (3) of a ballistic material which serves as support for the second layer and together with the external layer (1) results in a lower fragmentation of said plurality of ceramic parts and a second block (B) which is adequate to permit the retention of the impact element preventing the penetration of the same, having said block a plurality of sheets (4) superimposed one to the other and made out of a ballistic material of a known type.
- Each of the sheets (4) of the second block (B) is coated by its front and back surfaces with a layer of a gliding flexible and plastic material, so that in a bending action of the protection structure, each of the sheets (4) glides smoothly in respect to an adjacent sheet. Preferably, the above mentioned gliding flexible material consists in a polyethylene film.
- Also, in an alternative embodiment, said sheets may be made out from a ballistic material to which a water proof flexible product has been applied in both of its surfaces by means of an immersion bath or by application by means of a painting pistol, atomization or similar.
- As may be appreciated more clearly from
figure 2 , the ceramic parts may consist in flat bodies (5) of reduced thickness which have a hexagonal outline, so that this layer acquires a degree of flexibility in one sense due to the above described configuration of the structure. - In a particularly preferred embodiment of the invention, a first layer of an elastic adhesive material (6) is located between the first external layer (1) and the second layer (2) forming part of the first block and an additional layer of elastic adhesive material (7) which is located between the second layer (2) and the third layer (3) forming part of the first block (A).
- The details, size, dimension and other accessory elements, as well as the materials employed in the manufacture of the protection structure of the invention will have the possibility to be substituted by other technically equivalent not departing from the essentiality of the invention nor from the scope of the same as defined by the following claims.
