Definitions

  • the present invention relates to an extremely light container with a capability to entrap splinters and damp the effect of shock waves on the immediate surroundings on detonation or deflagration within the container of explosive charges of limited size, for example of the nature of hand grenades or small-scale terrorist explosive devices.
  • the container, or "mini detonation chamber” according to the present invention is intended to deal with one sole detonation and is, thereafter, to be considered as used. Hence, it is primarily intended to be used in the disarming of explosive charges in such places where protection for the immediate surroundings is given high priority.
  • This prior-art disclosure relates to a mini detonation chamber based on two powerful mutually interposed steel cylinders with open ends, of which the one is, first, fixedly retained in a frame with its longitudinal axis horizontal and, secondly, is bevelled towards the outer corners such that the second steel cylinder, which is of greater diameter than the first, may be passed over the first with its longitudinal axis in the vertical direction.
  • the second steel cylinder will, in this instance, seal off the open ends of the first cylinder.
  • the prior-art arrangement includes buffer material which is disposed interiorally in the inner cylinder and which may be said to consist of foamed plastic, vermiculite or the like.
  • the mini detonation chamber according to the present invention has now been designed in such a manner that only light-weight materials such as aluminium sheet and hard mineral wool have been required. Consequently, it will be extremely light as compared with prior-art apparatuses of similar type. Moreover, it is designed in a manner which could well be described as following the box drawer principle, which makes it very simple to use.
  • the mini detonation chamber according to the present invention consists, like the detonation chamber according to the above-mentioned U.S. patent, of two mutually movably interposable tubular or cylindrical parts, but the problem solution itself is completely different.
  • both of the cylindrical parts according to the present invention are disposed in one another with coincidental longitudinal axes, so that the outer portion which consists of an open-ended tube of reinforced jacket surface, concentrically surrounds the inner portion which is wholly enclosed apart from an aperture along one portion of its jacket surface and is provided with powerfully reinforced ends designed with deformation zones.
  • the inner portion is designed to absorb longitudinal stresses and further to be supported in the radial direction by the outer portion which, in its turn, is designed to absorb radial loadings but be preserved completely from longitudinal stresses.
  • the inner portion In order to "load" the chamber, i.e. place the explosive charge under consideration therein, the inner portion is quite simply partly withdrawn from the outer in exactly the same manner as a drawer, whereafter the explosive charge is passed down through the aperture in the jacket surface of the inner portion.
  • a suitable accommodation seat which centers the charge is disposed in the inner portion immediately beneath the aperture.
  • the accommodation seat may, for example, consist of a mesh basket possibly reinforced with buffer material, for example in the form of a water sack.
  • the inner portion may be retracted and locked in its retracted position. The lock will never be influenced in the event of detonation, so it need not be of particularly powerful design.
  • smooth and corrugated, preferably trapezoidal aluminium sheet and hard mineral wool mats as our point of departure.
  • the jacket surface of the outer portion consists, according to the present invention, of a plurality of layers of smooth and corrugated aluminium sheet, in which the corrugation creases extend in the longitudinal direction of the portion, together with hard mineral wool mats, while the inner portion is constructed of smooth aluminium sheet with its ends reinforced by a plurality of layers of crosswise laid strata of corrugated sheet and hard mineral wool mats.
  • the apparatus shown thereon consists of a first outer portion 1 in the form of an open-ended cylinder or tube consisting of an outer aluminium sheet 2, a hard mineral wool mat 3, a trapezoidal profile aluminium sheet 4 and an inner smooth aluminium sheet 5.
  • a first outer portion 1 in the form of an open-ended cylinder or tube consisting of an outer aluminium sheet 2, a hard mineral wool mat 3, a trapezoidal profile aluminium sheet 4 and an inner smooth aluminium sheet 5.
  • annular sealing ends 6 and 7 to prevent moisture and the like from entering in between the layers.
  • the end plate 7 is slightly larger than the thickness of the jacket wall and functions in this way as an arrest against excessively long displacement of the inner portion 9 which is displaceably disposed within the portion 1.
  • Two vents 8 in the form of through conduits of limited diameter are also disposed in the jacket wall of the portion 1.
  • the sedond, inner portion 9 is wholly enclosed apart from an aperture 10 in its jacket wall 11.
  • the jacket wall is manufactured of smooth aluminium sheet and displays no particular reinforcements, since it is not intended to absorb any actual radial stresses. In that direction, this portion will be supported by the outer portion 1. In the longitudinal direction, the natural mechanical strength of the sheet will be sufficient.
  • the ends of the inner portion are greatly reinforced and provided with deformation zones. The ends are, thus, constructed from a smooth inner aluminium plate 12, four layers of crosswise disposed trapezoidal profile sheet 13-16, one layer of hard mineral wool 17, an outer smooth aluminium sheet 18 and, finally, a number of outer reinforcement profiles 19 disposed transversely of the end.
  • a handle 20 for manoeuvring the inner portion.
  • guide bars 21 and guide rails 22, as well as locking means 23 for retaining the portion 9 within the portion 1.
  • the locking means may be of relatively simple design, since they will not be exposed to major stresses but are simply provided to retain the inner portion in place. This should, namely, lightly run along slide rails and guide bars within the outer portion so that a suspected explosive charge is not subjected to any unnecessary stresses.
  • the vents 8 in the outer portion are in register with the aperture 10 when the inner portion is fully retracted in the outer portion. It will further be apparent from Fig. 3 that the aperture 10 is completely free when the inner portion 9 is wholly withdrawn from the outer portion 1.
  • the inner portion 9 is also provided with a seat for the charge.
  • this is in the form of a mesh basket 24 in which, in the illustrated embodiment, a buffer or damming in the form of a water sack 25 has been placed, thereon the charge 26, and finally a second water sack 27.
  • the portion 9 may be moved into place and the locking means 23 closed. Thereafter, the charge consisting, for example, of a terrorist explosive device which could without difficulty have been detonated on site, may be removed under acceptable protection for the immediate surroundings or, if deemed more favourable, be detonated immediately within the detonation chamber.
