Definitions

  • the present invention essentially relates to a device for protecting against perforating tools, for example in the form of diamond crowns.
  • the balls used were of a relatively small diameter.
  • they were distributed in the wall in a somewhat random manner and they had a certain degree of freedom in the horizontal plane, so that they could not play the role of an effective barrier to the punching tools having large diameters.
  • the object of the present invention is in particular to remedy the above problems by proposing an improved device for protection against attack with piercing tools, this device being remarkably effective, in particular by the fact that the balls are incorporated and distributed in the wall in a very particular way so as to ideally resist attacks by large diameter perforating tools.
  • the subject of the invention is a device for protecting against perforating tools, such as for example coring tools, and of the type comprising a support provided with balls incorporated and mounted for free rotation in this support, characterized in that that said balls are each housed in a closed box integral with said support, all of the ball boxes forming a regular checkerboard configuration in this support.
  • the aforementioned support consists of at least one grid or the like, the openings of which ensure the positioning and / or fixing of the aforementioned cases.
  • the aforementioned support or grid is integral with a base plate by means of fixed spacers, for example welded, both on the grid and on said plate.
  • a second grid is fixed on these spacers and cooperates with the aforementioned base plate to position the ball housings between this second grid and said plate.
  • the boxes containing the balls have tabs, projections or the like ensuring their attachment to the grid cited first and constituting the support.
  • the closed boxes containing the balls have a circular or polygonal section and can form a single piece or else each comprise a body and a cover.
  • the spacers are constituted by sheets welded by their edges on the base plate and on the grids.
  • the diameter of these balls is preferably close to 30 millimeters, while the distance between the axes of two adjacent balls along a diagonal is between approximately 40 and 60 millimeters.
  • the invention also relates to a composite wall provided with a device meeting one or the other of the above-mentioned characteristics and to which is added a flowable material, such as for example concrete, synthetic rubber or the like.
  • FIG. 1 is a partial view in elevation and in section along the line I-I of FIG. 2, of a composite wall comprising a device according to the principle of the invention, and
  • Figure 2 is a top view of this wall and according to the section made substantially along the line II-II of Figure 1.
  • a wall 1 equipped with a protection device essentially comprises balls 2 mounted for free rotation in this wall while being firmly held in the horizontal plane.
  • each ball 2 is housed in a closed housing 3 which is made of a suitable material, such as for example a plastic material.
  • the balls 2 can rotate freely in their respective housings 3.
  • the housings 3 are embedded and positioned in the openings 4 of a grid G which, according to the example of embodiment shown, is constituted by metallic wires 5 interlaced perpendicularly to one another. 'other.
  • the side wall of the boxes 3 has lugs, projections or the like 6 which are clearly visible in FIG. 1 and which allow the boxes 3 to be hooked onto the metal wires 5 of the grid G.
  • the set of closed boxes 3 forms a regular checkerboard configuration in the grid, as shown in A, B, C, D, E and F.
  • the grid G is secured to a base plate 7 by means of spacers 8 fixed both on the grid G and on the base plate 7. More specifically, the spacers 8 are constituted by metal sheets welded by their edges to the plate base 7 and on the grid G as shown respectively in 9 and 10 in FIGS. 1 and 2.
  • the housings 3 can be made in one piece, forming a cage for the balls 3, or can be made in two parts, as shown in the figures, and namely a body 3a and a cover 3b.
  • the boxes 3 may have in cross section a circular shape, or else a polygonal shape, such as square for example, if the openings 4 of the grid G are square.
  • a housing 3 which has a square shape, while the housing 3 which is on the same line and to the left of the housing square, has a circular shape. But, in both cases, the housing 3 remains firmly positioned in the plane through the openings of the rrille G as well as the ball 2 which is contained therein and which rotates freely in said housing.
  • the diameter of the balls 2 is preferably close to 30 millimeters. As for the distance d between the axes of two adjacent balls 2 along a diagonal, as can be seen in FIG. 2, it is preferably between approximately 40 and 60 millimeters.
  • a flowable material 14 such as for example concrete or synthetic rubber is added to the assembly described above.
  • the whole assembly is embedded in this material with the exception of the balls 2 enclosed in their housings 3 so that they are always free to rotate in said housings.
  • a composite wall 1 has therefore been produced according to the invention which can, for example, be fitted to a safe and which comprises balls positioned in a checkerboard configuration and firmly held in the horizontal plane by means of the housings 3 which contain them and which are hung in the openings of grille G.
  • a wall has therefore been produced according to the invention internally provided with an arrangement of very specific means and combined in a very special configuration, so that said wall constitutes an extremely effective barrier to the penetration of perforating tools, and in particular diamond crowns. having a large diameter.
