Abstract: A transportable, reusable rapidly assembled and disassembled, resizable modular, security enclosure utilizes a stepped panel construction. Each panel has an inner portion and an outer portion which form joints. A plurality of channels can be affixed to selected joints of the panels. Panels can be affixed to a base member and then affixed to one another by the use of elongated pins extending through the channel joints. Alternatively, the base member can be omitted and the panels themselves can be used as the floor of the enclosure. The pins will extend generally parallel to the joint in which they are located. These elongated pins are readily inserted into and removable from the channels in a predetermined sequence to allow assembly and disassembly of the enclosure. A door constructed from panels is used to close the opening to the enclosure.

Abstract: A cover for use with a container (1) comprises one or more layers (11, 12, 15) of high tensile strength, high stretch resistance flexible material which are capable of resisting penetration by bomb blast and fragmentation and which are adapted so that the cover can expand and absorb and/or channel the blast from within the container (1). For this purpose, the layers of flexible material are interconnected by hook-and-eye type fabric fasteners, which can give or release under load to allow controlled expansion of the cover in the event of an explosion. The container may be the type used to carry cargo or luggage on an aircraft and placing the cover (11, 12, 15) about the container a bomb secreted in the luggage or cargo will be prevented from destroying the aircraft.

Abstract: A shield member is disclosed for protecting a cylinder barrel. In one embodiment, the shield member is received upon the tie rods that secure the head and end plate of the cylinder assembly. This shield member protects the surface of the cylinder barrel from any accidental impact. A channel portion at an inner periphery of the shield member will bow inwardly to absorb the force of any impact that is received on the shield member. The shield member is preferably extruded from urethane and may be cut to the appropriate lengths for a particular cylinder assembly. The shield member may be utilized on any one of the four quadrants of a standard cylinder barrel. That is, if one of the quadrants of the cylinder barrel is not in danger of impact, it is not necessary to have a shield member disposed on that particular quadrant. A second embodiment is disclosed to protect cylinder assemblies that do not use tie rods.

Abstract: A building panel module incorporating spaced inner and outer wall surfaces of metallic sheet construction to provide both longitudinal and transverse load carrying capabilities. The module includes interior baffles that are positioned between the inner and outer wall surfaces and that overlap each other to prevent direct pathways between the inner and outer wall surfaces so that ballistic projectiles that penetrate one wall surface must also pass through the baffles before impacting the other wall surfaces, thereby reducing their energy level to such an extent that they do not penetrate the innermost wall surface. Additionally, the module incorporates one or more integral I-beam elements that provide substantial longitudinal load carrying capacity, as well as providing resistance to transversely applied loads, such as wind loads, blast loads, and the like.

Abstract: A reactive armour construction comprises a rigidly fixed outer layer and a relatively loosely fixed inner layer mounted on a structure to be protected in such a way that when a projectile penetrates at an oblique angle the outer layer and is incident upon the inner layer, the inner layer is allowed to move laterally relative to the outer layer thereby disrupting the line of attach of the projectile.

Abstract: For framing plate type panels a composite section is used which is fitted together from a center part (3) and two lateral parts (4,5). The stay type center part (3) has two stay segments (6,7 ) which are spaced from each other and connected together through a pair of insulating strips 8. On the side away from the respective panels (1,2) the two lateral parts (4,5) are provided with reinforcement sections (10). Threaded studs (12) distributed at intervals over the length of the composite section connect the reinforcement sections (10) and hence the section parts disposed therebetween with one another. This results in a stable union of the composite section, which not only is given a bombardment-inhibiting effect by the reinforcement sections (10), but also is able to withstand high tensile stresses of the center part (3) and to prevent deformations of the lateral parts (4,5).

Abstract: An improved safe is provided which offers the security of currently known more complex safes at substantially less cost. The safe preferably includes a cabinet having apertured door frame structure, with a door having inner, outer and sidewalls. Locking apparatus located within the door includes a series of selectively operable toggle mechanisms, each having a pair of pivotal links coupled to a locking bolt. The locking bolts are designed to extend through the aligned frame and door apertures to lock the door. The frame structure is formed of interconnected, seamless webs integral with the cabinet walls and presenting a recess to receive the door lip. Additional security is achieved by reinforcing the door lip with flange structure forming a part of the marginal door frame and by attaching the handle to the actuator for the toggle mechanisms so that excess force renders the handle inoperative.

Abstract: Vandalism resistant building modules suitable for detention and secured storage facilities provide good architectural properties and significant resistance to noise, fire and impact. Thus, steel shell modules are welded together to produce steel inner and outer walls. The modules contain strengthening and bullet deflecting internally directed steel baffles and various types of insulating materials. Construction is facilitated by providing modules that are welded together along only two lines coinciding with mating end positions on the steel plate inner and outer walls. Three steel panel pieces are formed into a module, each being partly triangular in cross section so that only one weld seam between two of the panels is required in assembling the three pieces which thereby form the internal baffles at angles for deflecting bullets.

The face panel is in a specific spaced relationship to the inner structural panel such that the energy of an impacting projectile is distributed over a large area and the face panel is allowed to flex inwardly in the absorption of such energy.

Abstract: A case for securing valuables which includes a plurality of interconnected panels defining an interior space for location of the valuables. A door provides access to the space and a lock normally maintains the door in the closed position to prevent such access. Some of the panels employed for forming the space include inside facing surfaces and connectors such as threaded studs are positioned on these surfaces. Cooperating connectors such as openings for receiving the studs are defined by other panels so that upon assembly of the respective panels, access to the connectors is available only from within the interior of the case. The individual panels are readily transportable for convenient location and assembly; however, the case, once assembled, cannot be so readily moved from its location.

Abstract: A safe having an outer shell mainly of plastic material, an inner liner of metal, and a filling of heat-resistive material between the shell and the liner. The safe body has a separate cover or door across the top of the body, and when the door is removed, it allows unhampered access to the complete area of the liner, which constitutes the storage space for the articles to be protected. Both in the safe body and the separate door, the filling material is put in while in a flowable condition, and filling is stopped when the space is not quite full. The panel members which are then put in place to close the filling openings have projections which make contact with the filling material to give stability and firmness to the panel members even though large areas of the panel members may not be in contact with the filling material. A simple latch and key mechanism is also disclosed.

Abstract: A walled structure forms an inner protected area and is made up of prefabricated roof, floor, side and end wall members. These members have jointed overlapping connection with adjacent members with peripheral edges thereof having offset surfaces from each other across the seam of the joint to provide non-continuous burglar-proof seams which lead from the exterior of said vault to the inner protected area. The joints are arranged to provide a minimum of exterior seams. The members of the vault are secured together by disconnectable weld plates for the purpose of disassembling the structure in temporary installations.

Abstract: A safe deposit box nest includes an outer housing into which are assembled a number of sheet metal partitions and shelves to form compartments. In order to eliminate the need for individually fitting each compartment door, each such door is hinged to and strikes against posts formed by extruded members such as aluminum attached to the front of the partitions. To the same end the forward edges of the shelves are disposed between the posts and doors and are folded rearwardly upon themselves and compressd to form shelf edge portions of uniform thickness. Finally, the nest is constructed in a manner which reduces welding to a minimum and helps insure accurate and uniform compartment openings to which the doors are applied.
