ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a modular security safe and more particularly to a high security modular security safe which includes a plurality of panels interconnected together with bolts which are offset from the edges of the panels by use of security bolt boxes attached to interior rabbeted faces of top and bottom panels. The present invention also relates to a method of manufacturing the panels comprising the safe, and to a method of making the panels to form a safe.
2. Related Art
Security safes for the household protection of valuables, currency storage at convenient stores, and other small security applications are in wide scale use. Typically, safes employed for such applications are much smaller and lighter than those used in banks and other high security situations. The need for the smaller and lighter design is to facilitate the delivery and placement of these safes in houses and buildings typically not designed to withstand the weight of a large safe (4000-6000 pounds) or the prohibitive size of the safe.
As a result, these lighter safes typically serve only as a deterrent to burglary attempts rather than a sophisticated defense against professional burglary.
In order to increase the security of small application security safes, efforts have been made to design modular safes which can be moved piece by piece to a location where it will be used and then assembled. The modular style safe allows for ease of transportation, but prevents such transportation once assembled. It also provides a higher degree of security than other small application safes which, in some instances, can be carried away from the location.
However, despite the increased weight of modular safes currently known, the very nature of the modular design reduces the security of such a safe in comparison to a one-piece cast safe. Up until now, modular security safes, by the very nature of being modular in design, have been ineffective in preventing attacks by professional burglars. While modular safes are an improvement upon previous minimum security safes which can be carried away or easily attacked, modular safes, while immobile, still are vulnerable at the points of connection between the plurality of components that make up the safe.
Accordingly, what is desirable and has not heretofore been developed, is a modular safe which has the desired benefits of immobility and strength, with the added advantages of being impervious to attack at the critical joints of the modular pieces.
Some of the numerous efforts to provide modular safes are as follows:
Ouellette, U.S. Pat. No. 5,488,914, discloses a security device for boxes. The security device includes a cabinet device which has an open top section into which a bottom portion of the box which is to be secured is inserted into the upper inner portion of the cabinet device. The bottom base includes a locking device for securing the cabinet onto a supporting surface such as a floor.
Nikoden Jr., U.S. Pat. No. 4,426,935, discloses a case for securing valuables which includes a plurality of interconnected panels defining an interior space. The individual panels are readily transportable for convenient location and assembly; however, the case, once assembled, cannot be so readily moved from its location. Some of the panels employed include inside-facing surfaces and connectors such as threaded studs, while 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 device further discloses top and bottom panels which are interconnected to the side walls of the enclosure. The bottom panel is fitted with filler plates to eliminate any gaps along the bottom side edges of the case. It is further disclosed that said panels may be made of sheet metal, having 90degree bends for forming the respective panel side edges. A double bend is then utilized for forming the respective lips which prevent access to the interconnecting bolts from the exterior of the security space.
Sands, et al., U.S. Pat. No. 4,389,948, discloses a vault constructed by assembling together a plurality of separate, pre-fabricated panels. Each perpendicular comer of the assembled vault is provided in a panel which extends integrally from the respective comer to define significant portions of both of the adjacent sides of the vault, thereby avoiding the security weakness of separate orthogonally-jointed panes at these comers. Each panel additionally comprises a steel plate upon which is cast a barrier material of high penetration resistance, but relatively low weight, fiber-reinforced concrete.
In one arrangement, there are four comer panels with two of said panels being interconnected by a uni-planar panel to define a first side of the assembled vault, and a space between the free edges of the other two said comer panels to define a door opening for the assembled vault on a second side thereof opposite to said first side. Said uni-planar panels also serve to provide as the top and bottom of the enclosed structure. These uni-planar panels can be inserted in multiple groups in order to form an increasingly large vault space. Except for the edges of the panels which define the door opening, each panel is formed around its edges to provide half lap joints which interfit with the corresponding formations on the neighboring panels. The overlapping joints, so-formed, insure accurate relative location of the panels and preclude the possibility of direct access being gained to the interior of the vault through the joints. All panel-to-panel connections are made internally, and none of the fixing is visible from the exterior of the vault. Each joint between adjacent corner and uni-planar panels is secured by means of a steel flitch plate which is welded along the vertical edge of one of the abutting panels and has a series of drillings which align with tapped holes along the vertical edge of the uni-planar panel, the screws being passed through the flitch plate and into the holes. Joints between the corner and rear panels and the floor and roof panels are similarly secured by steel angles which have a series of joints in each leg, which align with tapped holes along the adjacent horizontal edges of the panels, the screws being similarly passed through the angles and into the holes. In order for this joint angles to function as one structure, they must be welded together. The reinforced concrete layer of the panels is evenly distributed with randomly oriented masses of steel fibers providing a density in the range of 14,000 pounds per square inch.
Sands et al., G.B. Patent No. 2,081,335, is the British counterpart to the above-described patent issued to Sands, et al., U.S. Pat. No. 4,389,948.
Stone, U.S. Pat. No. 4,388,874, discloses a prefabricated concrete vault with a plurality of concrete members having jointed overlapping connections with adjacent members with peripheral edges thereof having offset surfaces for each other across the seam of the joint to provide non-continuous burglar-proof seams. In other words, in each of such joints, edge surfaces formed by the groove or rabbet-type overlap provide surfaces or edges which are offset from each other so that there is no straight-through seam or direct path of entry. A plurality of metal plates are anchored along the edges of the panels and are welded together to join the panels together.
While a minimum of exterior seams are visible, giving the appearance of a permanent-type installation, the weld plates, which are welded into position in order to hold the separate portions together can easily be released from each other merely by burning out the welds and the component parts can then be transported away from the site. The result is a security safe which is highly secure in nature, but at the same time highly transportable, if necessary.
