Definitions

  • ABSTRACT -A bulletproof baffle member for use within the opening 521 vs. Cl 109/215, 109/585, 89/36 of bulletproof window or enclosure comprising a! [51] Int. Cl E06b 7/30 least one p of baffle elements j n d t n an th r 58 Field of Search.... 109/10-215, 49.5, 58.5, as; to form a symmetrical obliquely shaped arrangement 39/36 R, 36 A with respect to the plane of the window and including a core material intermediate to the elements to retain [56] R ferences Cit d and trap a deflected bullet or projectile.
  • baffles in this arrangement along with the use of metal as a material for the baffles has resulted in the possibility of a bullet fired into the baffles being caused to ricochet, with the result that the bullet passes through the speech channel into the enclosure.
  • the person within the enclosure is endangered by the glancing projectile.
  • the material used in the baffle construction is of sufficient hardness to provide bulletproof characteristics which results in the increased tendency for the bullet to richochet.
  • the main object of this invention is to provide a security baffle arrangement for the safety of personnel which prevents or reduces the possibility of a bullet fired at the baffle from richocheting.
  • Another object is to provide a design for a baffle arrangement where the bullet is caused to deflect into an absorbing material for the purpose of holding or trapping the projectile.
  • a further object is to provide a baffle arrangement for the security of personnel which is both reliable and yet economical to fabricate and install.
  • This invention is directed to a bulletproof baffle arrangement for use in the communication opening within a bullet-proof window or enclosure.
  • An enclosure such as this is usually provided in banks or cashier areas to protect the cashier or clerk from the danger of robbery.
  • the baffle arrangement includes at least one pair of baffle elements joined to one another by an intermediate member or section and arranged in the communication opening in such a way that the baffle elements extend obliquely and symmetrically within the opening relative to the plane of the window. It is understood that the intermediate member is to be generally located within the plane of the window.
  • a core or absorbing section is provided in conjunction with the intermediate member or the intersecting area between the baffle elements whereby a bullet or projectile deflected or shot into the core material will be retained and absorbed so as to prevent ricocheting.
  • Each baffle element is designed of sufficient thickness and material to be considered bulletproof.
  • baffle elements will absorb the impact of the fired bullet and deform the bullet to dissipate its stored energy with a minimum possibility of ricocheting.
  • FIG. I is a diagrammatic cross-section view of a baffle member according to the present invention.
  • FIGS. 2, 3 and 4 are diagrammatic cross-sectional views of further embodiments of the present invention.
  • a bulletproof barrier which includes a bulletproof glass or the like forming a window 1 or enclosure around a pro tected area.
  • a metal baffle member assembly shown generally at 3 is positioned within an opening 2 in the window I for the purpose of verbal communication and/or the passing of objects, such as money.
  • the assembly 3 is composed of baffle elements 4, S and 4a, 5a, wherein each pair is arranged so that the elements 4, 5 and 4a, 50 extend obliquely from the plane of the window 1.
  • Each pair of baffle elements is arranged symmetrically relative to the plane of the window, and the connecting element or intersection of baffle pair lies within the plane of the window.
  • the two pairs of baffle elements 4, 5 and 4a, 5a are arranged in a cross or cruciform shape.
  • a longitudinally extending intermediate section 6, 7 interconnects the two baffle elements on each side of the plane of the window 1, making it possible to form the two elements 4, 4a or 5, So as one single unit.
  • a core member 8 Between the bafile units 4, 4a and 5, 5a is arranged a core member 8.
  • the balfle elements and intermediate sections can be formed from any material which exhibits a bulletproof characteristic, such as metal, hardened glass, or the like.
  • the core member 8 is also formed from bulletproof material, but this material must in addition have the ability of being able to absorb or trap a bullet which is not deflected.
  • the core 8 can be rigidly connected to the intermediate sections 6, 7 of the baffle members in any suitable manner such as by the use of screws, rivets, or the like, or by various joining processes such as welding, pressing, adhesive bonding, etc.
  • the ends of the baffle members and core are firmly secured to the opposite edges of the window 1 around the opening 2 or, if desired, can be secured to the frame or support for the window. Other methods are possible depending upon the particular design and use of the baffle assembly.
  • baffle elements 4, 5 and 4a, 54 extend sufficiently beyond the edges of the opening 2 in the bulletproof window I such that there is no possibility of a bullet passing directly through the opening without being diverted.
  • the baffle elements are formed in a thickness which will provide the bulletproof characteristics desired, and the end portions of each of the baffle elements may be tapered or reduced in cross-section from a point beyond the furthest calculable impact point for a bullet, as indicated by the dotted lines in FIG. 1, to the outer edge 10, as shown with respect to baffles 4a and 5a. This modification tends to improve the appearance of the baffle assembly.
  • baffle arrangement 3 By the addition of the core 8 between or at the junction of the baffle elements 4, 5 and 4a, 5a, a bullet striking the inner surfaces of a baffle pair deforms the elements and is deflected into the core portion.
  • the bullet in deforming the element material is flattened or distorted, thus removing the bullets ballistic flatness and thus its striking power.
  • the bullet is then deflected into the core material 8 where the remaining energy is absorbed and the bullet is essentially trapped. If ricocheting from the elements 4, 5 or 4a, 5a does occur, the bullet will be essentially spent and reduced in velocity so that it is no longer dangerous. In most cases, the bullet will not have a penetrating effect but will more or less drop downwards as its energy is spent.
  • the baffle arrangement 3 will serve as a reliable shield and bullet trap.
  • the baffle arrangement member 11 includes a core 8a design which is not exposed to the communication opening 2.
  • the inner edges of the intermediate sections 6, 7 are provided with side facing edges 12, 13.
  • the edges or legs l2, 13 are intentionally kept thin and are separated from the core material 8a by void or hollow spaces I4, 15.
  • a bullet striking the thin side members l2, 13 deforms both itself and the members l2, 13. These members bend inwardly in the direction of the hollow spaces 14, so that a bullet entering the area between the baffle elements 4, 5 or 40, 5a is trapped in the hollow space 14 or 15 and the core material 80.
  • FIG. 3 another embodiment of the present invention is shown wherein the intermediate sections 6, 7 of the baffle portions 4, 4a and 5, 5a directly contact or engage their inner surfaces.
  • the baffle elements abut each other and form an acute angle between elements.
  • angular flexible strips l7, l8, fabricated from the same material as core element 8 or 8a, are located and shaped in substantially a triangular cross-section so as to complement the acute intersecting angle.
  • the strips l7, 18 are connected to the baffles in any suitable manner such as by a retaining or fastener means 19.
  • the embodiment shown in FIG. 4 is similar to the previous embodiment except that the intermediate sections 6, 7 are designed with a base surface extending transversely to the plane of the window 1 and having an additional cross-sectional width.
  • the base surfaces lie parallel to the edge of the opening in window I.
  • the strips 21 fabricated from flexible material such as that used in core 8 or 8a serves as a bullet trap and is attached to the base sides 60, 7a and 6b, 7b. Retainer or fastener means 22, 23 are used to secure the strips to the base surfaces. It is to be understood that the trap strips 21, l7, l8 and the core members 8 or 8a are intended to run the full length of the baffle arrangement.
  • the surfaces located within the plane of the window 1 and lying between the baffle elements 4, 5 or 40, 5a and forming the edges of the communication openings 2 can be provided with roughened surfaces, ribs or surface protuberances, or the like, in order to better trap and retain the bullet or projectile. If desired, these surfaces when viewed in cross-section can be curved in a concave or convex manner to improve their functional capability.
  • the baffle elements can be disposed in any arrangement so long as a general cruciform or X shape is obtained when used in a double pair arrangement.
  • the intermediate sections 6 and 7 can be completely omitted if desired.
  • the pair are arranged in a V-shape with or without the intermediate section.
  • the apex or intersecting portion between the baffle ele ments would be connected directly to the bulletproof glass of the window or its frame.
