Definitions

  • This invention relates to flexible protective cladding and is particularly concerned with flexible protective cladding which may be used as body armour to afford protection against gun shot and knife or needle like piercing implements or weapons.
  • U.S Patent 4 559 251 discloses an arrangement where hexagonal hard nylon plates are connected together by means of various different shaped connectors.
  • the nylon has its own degree of resilience and flexibility and therefore measures are not required to increase this flexibility.
  • the device does in fact exhibit risk of penetration through having a number of chinks.
  • the present invention is concerned with providing protective cladding making use of more rigid plates, for example of pressed metal which is more resistant to the offensive implements, while solving the problem of maintaining flexibility.
  • the present invention provides flexible protective cladding comprising a plurality of overlapping plate like members in which a plurality of the plate like members are of a first kind which each comprise a central body portion and a peripheral flange provided with an array of apertures and that a plurality of the plate like members are of a second kind in the form of discs carrying pin like projections, a plurality of plate like members of the second kind lying peripherally round each plate like member of the first kind so as to overlap the flange characterised in that the plate like members of the second kind are flexibly linked to those of the first kind through at least one of the pin like projections being loosely located in a respective aperture in the flange, and that the plate like members of the second kind are each retained by a disc shaped retaining member located on the obverse side of the flange of each respective plate like member of the first kind.
  • each plate like member of the first kind is trapped between the plate like members of the second kind and the disc shaped retaining members on the obverse side.
  • the various plates are flexibly liked together and can conform to a body shape and yet can be proof against attack through enabling any potential chinks to be covered either by the plate like members of the second kind or the disc shaped retaining members on the obverse side of the flange.
  • each aperture of the peripheral flange within which a pin like projection is located is sufficiently greater in diameter than that of the pin like projection to enable adequate flexibility to be achieved.
  • careful selection of the dimensions of the pin like projection in relation to the aperture can ensure that the plate like members hold together under various different forms of impact load and of flexural bending.
  • each adjacent plate like member of the second kind around the periphery of a plate like member of the first kind are all the same, i.e of a similar shape. This has advantages in manufacture as well as making adequate cover of any potential chinks easier.
  • each plate like member of the first kind has a dished convex shape and this has the advantage of permitting flexible movement of the linked plate like members when they are curved in a body covering shape.
  • the retaining member is retained in relation to its respective plate like member of the second kind by virtue of a centrally located pin like projection extending from the said plate like member and the retaining member is mounted on the said centrally located pin like member.
  • This may be achieved by a spring clip washer.
  • each plate like member of the first kind is that of a hexagon
  • each plate like member of the second kind may also be in the shape of a similar hexagon so that the hexagons nest together to provide a substantially continuous external surface. This not only has a pleasing external appearance but helps to ensure adequate cover of the protective area with the minimum risk of chinks existing.
  • the peripheral flange of each plate like member of the first kind is preferably duodecahedral in shape to provide a central opening between adjacent plate like members of the first kind.
  • the duodecahedral shape is derived from the fact that the hexagon if it has its vertices clipped off becomes a duodecahedron.
  • each retaining member is disc like in shape and this has the advantage that it can provide additional cover to eliminate any potential chinks in the armour.
  • each retaining member can extend to cover the line between adjacent plate like members of the first and second kind.

Abstract

Revêtement de protection souple destiné en particulier aux gilets de protection à l'épreuve des balles de pistolet et des couteaux ou des outils pointus perforants, comprenant des plaques hexagonales forgées, par exemple, à partir d'aluminium. Un premier type (59) desdites plaques possède une zone centrale hexagonale (60) et une bordure dodécagonale (61) recouverte d'un deuxième type de plaques hexagonales (63) incorporant des goupilles de positionnement (65, 66) dont quelques-unes se fixent de façon souple dans des ouvertures (62) pratiquées dans les bordures (61) tandis que d'autres portent un élément de fixation en forme de disque (67) sur le côté opposé de la bordure. Ce système permet une couverture complète et souple de la zone à protéger. On décrit également divers formats non hexagonaux.
