   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to security and locking mechanism for the double door type security safe, vault or bunker wherein the door is constructed by conventional means or by modular panels, the security and locking mechanism utilizing a plurality of horizontal throw bolts and bolt channels to effectuate the sealing and locking of the double door. 
   2. Description of the Prior Art 
   Security safes and vaults are used for a wide variety of protection. Security safes and vaults can be room size as in the case with many bank safes or vaults and can vary in size down to a wall safe utilized in homes and offices. The sizes and scales of such safes and vaults can vary widely between these two extremes. Applicant is the holder of a series of patents, U.S. Pat. No. 6,044,776 and a divisional and continuation-in-part applications which have matured into patents set forth above there from for modular safes which would typically be utilized for all sizes of the safe-vault continuum. Applicant&#39;s module safes allow the safes or vaults of any size to be assembled in situ and still provide superior security and integrity and weight to the typical smaller safes utilized heretofore which could be easily breached or in many instances completely removed from the premises for being breached. 
   In order to increase the security of safes and vaults, 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. 
   Applicant has further developed the modular concept of safe or vault to include the ability to expand the safe or vault to a larger size utilizing the modular concept which would allow for an individual or entity having a safe or vault already installed of one particular size to be able to expand that safe or vault in situ, by utilizing additional modular panels and security devices such that the size of the safe or vault could be expanded in a geometric progression. 
   With Applicant&#39;s module and expandability characteristics, the time, expense and labor of moving and installing a safe or vault are obviated. Applicant&#39;s panels are limited to a weight of 200 pounds per panel and can allow for the installation and construction of a safe or vault without a third parties knowledge that a safe or vault has been installed. Still further, the modularity and expandability characteristics allow for the expansion of an existing safe or vault constructed of Applicant&#39;s modular panels to be accomplished without third parties knowledge of such expansion or existence of such safe or vault. This concept alone further heightens the security of the safe or vault. Since if no one knows of its existence except for the owner and the installer, no temptation exists to burglarize the safe or vault. 
   The present invention relates to a security and locking mechanism for a double door, double hinged, security safe vault or bunker wherein the double doors are constructed of either conventional construction or of modular construction as described in Applicant&#39;s prior applications and patents. If a security safe, vault or bunker is to be assembled in situ, the locking and security mechanism must be of a size and weight which is easily transportable yet will provide the necessary security. 
   The security and locking mechanism of Applicant&#39;s invention is comprised of a mechanism having a plurality of horizontal throw bolts which provide at least four contact points with vertically disposed bolt channels between the double doors and eliminate the need for vertical throw bolts necessitated by the prior art in which one of the double doors was secured to the second door by a plurality of horizontal interior throw bolts with the second door being secured to the frame of the safe vault or bunker body by a plurality of vertical throw bolts which were releasable only after the horizontal throw bolts of the first door were released and the door opened. Therefore, the opening of a double door, double hinged entry way required a two step process. 
   Applicant by incorporating modular elements as here after set forth in Applicant&#39;s prior applications can construct a double security door of desired height, and width, for varying sized security safes, vaults or bunkers. The security and locking mechanism can be dimensioned for such size door and the components installed in situ in a modular fashion using threaded fasteners. 
   While the securing or locking mechanism is particularly designed for Applicant&#39;s modular elements, it can also have application to a conventional double door, double hinged security safe, vault or bunker door which conventional security safe, vault or bunker and doors would suffer from the concomitant weight prohibitions, transportation and installation assembly difficulties, whereas Applicant&#39;s modular security safe, vault and bunker with modular door and security and locking mechanism can be transported to the site as separate elements and be assembled in situ. 
   Some of the numerous prior art efforts to provide modular safes can be found in the following references which are discussed in detail in Applicant&#39;s prior applications which are incorporated herein: Ouellette, U.S. Pat. No. 5,488,914; Nikoden, Jr., U.S. Pat. No. 4,426,935; Sands, et al., U.S. Pat. No. 4,389,948; Sands, et al, G.B. Patent No. 2,081,335; Stone, U.S. Pat. No. 4,388,874; Dippold, et al., U.S. Pat.

   DETAILED DESCRIPTION OF THE INVENTION 
   For purposes of continuity, Applicant sets forth a detailed description of Applicant&#39;s modular panels and safes as described in Applicant&#39;s prior applications. The improved modular security safe with offset security bolt box of the present invention is shown in  FIGS. 1   a ,  1   b , and  1   c . The safe is generally indicates at  20 . The safe  20  comprises a door  21  attached by a hinge  22 . The door  21  further includes a handle  23  for opening and closing the door. Combination lock means  24  is also provided in connection with the door  21  of safe  20 . 
   As can be seen in  FIG. 1   a  and in more detail in  FIGS. 1   b  and  1   c , the modular safe  20  includes a top panel  30 , a bottom panel  40 , a back panel  60  and side panels  70 . These panels,  30 ,  40 ,  60 , and  70 , the structure of which will be further discussed hereinafter, are interconnected by means of security bolt boxes  50  which attach the panels together to form the safe  20 . 
   Top panel  30  includes an outer portion  32  with an outer surface  33  and an inner portion  34  with an inner surface  35 . The inner portion  34  is generally smaller than the outer portion  32  in terms of length l and width w. A rabbet face  36  is created on the outer portion  32 . The rabbet face  36 , in connection with the perimeter  37  of the inner portion  34 , forms a step between the inner portion  34  and the outer portion  32 . 
   Similarly, the bottom panel  40  includes an outer portion  42  with an outer surface  43  and an inner portion  44  with an inner surface  45 . The inner portion  44  is generally smaller than the outer portion  42  in terms of length l and width w. A rabbet face  46  is created on the outer portion  42 . The rabbet face  46 , in connection with the perimeter  47  of the inner portion  44 , forms a step between the inner portion  44  and the outer portion  42 . 
   Attached to the inner surface  35  of the inner portion  34  of the top panel  30  is a security bolt box generally indicated at  50 . Likewise, a security bolt box  50  is attached to the inner surface  45  of the inner portion  44  of the bottom panel  40 . The security bolt box  50  includes a bottom face  52  and upstanding walls  54  to form a tray-like configuration. The upstanding walls  54  can be interconnected with the bottom face  52  or can be formed through a bending and folding operation that will be hereinafter described. The security bolt box  50  is attached to the inner portion  34  of top panel  30  and inner portion  44  of bottom panel  40  by means of anchor bolts (not shown) which extend through anchor bolt apertures  56  in the security bolt box  50 . The security bolt box  50  is also provided with attachment bolt apertures  58  extending about the upstanding walls  54  for receiving attachment bolts (not shown) to attach side panels  70  and back panel  60  with the top and bottom panels  30  and  40  to form the safe. 
   The back panel  60  is a generally rectangular wall formed with a plurality of bolt apertures along upper and lower edges for interconnecting with the security bolt box  50  by attachment bolts. 
   Side panels  70  include outer portions  72  and inner portions  74 . The outer portion  72  includes an outer surface or facia plate  73 , and the inner portion  74  includes an inner surface  75 . Like the top panel and bottom panel, the inner portion  74  is stepped in relation to the outer portion  72  creating a rabbet face  76 , which extends the length of the side panels, in a direction orthogonal to width W of the top panel  30  and bottom panel  40 . However, unlike the top panel  30  and the bottom panel  40  which are stepped down on all four sides, the top and bottom surfaces of the inner portion  74  remain flush with the outer portion  72 . Again, upper and lower edges of the inner surfaces  75  of the side panels  70  include apertures for receiving attachment bolts (not shown) that extend through the security bolt boxes  50  to join the side walls  70 , back wall  60  and top and bottom panels  30  and  40 . 
   Referring now to  FIG. 2 , a perspective view of the security bolt box  50  is shown. Again the security bolt box includes a bottom face  52  and upstanding side walls  54 . The box can be formed from a single sheet of metal with cut out corners and edges bent up to form the flat piece into a tray. Anchor bolt apertures  56  are punched through the bottom face  52  for attachment of the security box  50  to the inner surfaces  35  and  45  of the inner portions  34  and  44  of top and bottom panels  30  and  40 . Attachment bolt apertures  58  are punched through the upstanding walls for attachment of the security box to top panel  30 , back panel  60  and side panels  70 . 
   Referring now to  FIGS. 3 through 5 , the sequence steps in forming the panels is shown. A typical side panel is formed from a flat metal sheet which can be bent along edges thereof to form side walls  82  of side panel sheet  80 . Alternatively, the side walls  82  can be separately formed and attached by welding  85  or other means to bottom plate  86 . The side panel shell  80  comprises a shell bottom plate  86 , and two side walls  82 . Also, two shell end walls  84 , also typically made of a sheet metal material, and are attached by welding or other means to the bottom shell plate  86  to form the basic side panel shell  80 . Prior to forming or attaching the walls to the bottom plate, the shell bottom plate  86  has attachment bolt apertures  58  punched out at both the top and bottom edges thereof. If the side wall will receive lock bolts from the door of the safe, the shell bottom plate  86  is further punched with locking bolt apertures  88  along an edge thereof. These locking bolt apertures are then covered with covers  89  which comprise cylindrical bodies and caps and which define the bolt receiving space during the remaining fabrication steps. 
     FIGS. 4   a  and  4   b  show the next steps involved in the construction of the side panel. First, attachment bolts  57  are fitted through the attachment bolt apertures  58 . The attachment bolts  57  are then fitted with attachment plate spaced  63 . Thereafter a layer of expanded metal  90  is placed within the shell and covers the entire shell bottom plate  86  with the exception of the space occupied by the locking bolt aperture covers  89 . Next, the attachment bolts  57  are fitted through an attachment bolt plate  62  and locked into place by attachment nuts  61 . Then, a second layer of expanded metal  90  is positioned with the shell over the first layer. 
     FIGS. 5   a  and  5   b  detail the final steps of construction. The second layer of expanded metal  90  is secured in place by support brackets  94  which are held in place by support bolts  97 . Then, a single pour of high density concrete  100  is poured into the shell. Then the shell is vibrated to permit the concrete to settle, and the concrete is allowed to set. Importantly, the panel is constructed with the smaller, inner portion down so that only one pour is necessary. At this point all that is required is the attachment of a cover or fascia plate of any desired material which can be glued or otherwise attached to the exterior of the panel to provide any desired appearance. This step can be performed before or after the construction of the safe. 
   Construction of the top and bottom panes  30  and  40  follow generally the same method of construction. Likewise, the door  21  is a panel and does not require any special top and bottom filler panels. 
   It should be noted that the concrete can be formulated in accordance with the requirements of the application. For example, high density concrete can be used for high security application, while ready mix or other more economic concrete mixtures can be used in connection with lower security applications. Further, the other components of the panels, i.e. the expanded metal or reinforcement plates or aluminum or stone can be varied as desired. 
   After the panels set, the attachment bolts  57  and anchor bolts are removed from the panels. Security bolt boxes  50  are then placed on both the top and bottom panels  30  and  40 , and are fixed in place with the anchor bolts which pass through the anchor bolt apertures  56  of the security bolt box  50  and into security anchor bolt apertures at the top and bottom panel  30  and  40  where they are locked into place by anchor nuts  61  which remain within the panels from the panel fabrication process. The back and side panels  60  and  70  can then be attached to both the top and bottom security bolt boxes  50  and are fixed into place by the attachment bolts which pass through the attachment bolt apertures of the security bolt boxes fixed into place by the attachment nut to form the basic enclosure of the safe. Finally a hinged door can be affixed to the open wall to provide a complete security enclosure. Importantly, the on-site assembly process can be conducted on a ground-up basis. In other words, the bottom panel is positioned in a desired location and then the back and side panels placed thereon and attached thereto. The bottom thereby provides a flat, even work base or foundation. Also, with reference back to  FIGS. 1   a  and  1   b , it can be seen that the top and bottom panels  30  and  40  extends past the side walls  70  and rear wall  60  to optically hide the abutting seams of the vertical panels. 
   Finally, the inside of the safe can be finished off with a plate  55  that sits on top of upstanding walls  54  of the security bolt box  50 . Preferably, such a cover has a depending side wall at one side for covering the forward base seam between the security bolt box and the inner portion  34  or  44  of the top or bottom panel  30  or  40 . This cover plate can be screwed down on a bolt box and/or can be hingedly attached to provide for a “secret compartment.” Referring now to  FIGS. 6   a ,  6   b , and  6   c , another embodiment of the modular security safe of the present invention is shown. The modular security safe is generally indicated at  120  and includes a top panel  130 , a bottom panel  140 , and back and side panels  170 . These panels,  130 ,  140 , and  170 , the structure of which will be further discussed hereinafter, are interconnected by means of security bolt boxes  150  which attach the panels together to form a safe. Top panel  130  includes an outer portion  132  with an outer surface  133  and an inner portion  134  with an inner face  135 . The inner portion  134  is generally smaller than the outer portion  132  in terms of length l and width w. A rabbet face  136  created on the outer portion  132  which, in connection with the perimeter  137  of the inner portion  134 , forms a step between the inner portion  134  and the outer portion  132 . 
   Similarly, the bottom panel  140  includes an outer portion  142  with an outer surface  143  and an inner portion  144  with an inner surface  145 . The inner portion  144  is generally smaller than the outer portion  142  in terms of length l and width w. A rabbet face  146  is created on the outer portion  142 , which in connection with the perimeter  147  of the inner portion  144 , forms a step between the inner portion  144  and the outer portion  142 . 
   Attached to the inner surface  135  of the inner portion  134  of the top panel  130  is a security bolt box generally indicated at  150 . Likewise, a security bolt box  150  is attached to the inner surface  145  of the inner portion  144  of the bottom panel  140 . The security bolt box  150  includes a bottom face  152  and upstanding walls  154  to form a tray like configuration. The upstanding walls  154  can be interconnected with the bottom face  152  or can be formed through a bending and folding operation as previously described. The security bolt box  150  is attached to the inner portion  134  of top panel  130  and inner portion  144  of bottom panel  140  by means of anchor bolts (not shown) which extend through the anchor bolt box apertures  156  in the security bolt box  150 . The security bolt box  150  is also provided with attachment bolt apertures  158  extending about the upstanding walls  154  for receiving attachment bolts not shown to attach side and back panels  170  with the top and bottom panels  130  and  140  to form a safe. Importantly, the upstanding side walls  154  of the security bolt box  150  are recessed from the edges of inner portion  144  to provide an exposed portion of the inner surface  145  of inner portion  144  for facilitating interconnection of the top and bottom panels with the side and back panels  170 . 
   The side and back panels  170  include outer portions  172  and inner portions  174 . The outer portions  172  include an outer surface  173  and the inner portions  174  includes an inner surface  175 . Like the top panel and bottom panel, the inner portions  174  are stepped in relation to the outer portion  172  creating a rabbet face  176  which extends about all four sides of the side and back panels  170 . Upper and lower surfaces of inner surfaces  175  of the side and back panels  170  include apertures for receiving attachment bolts (not shown) that extend through the security bolt boxes  150  to join the side walls  170 , back wall  170  and top and bottom panels  130  and  140 . 
   Front panel  121  is constructed similarly to side and pack panels  170  with an outer portion and a stepped down inner portion along all edges of the outer portion. The front panel  121  can be hingedly attached to one side wall  170 . 
   The panels shown in  FIGS. 6   a – 6   c  can be constructed in the same manner as previously disclosed herein. 
   Referring now to  FIGS. 7   a – 7   c , another embodiment of the modular security safe of the present invention is shown. The modular security safe generally indicated at  220  and includes a top panel  230 , a bottom panel  240 , back panel  280  and side panels  270 . These panels  230 ,  240 ,  270 , and  280 , the structure of which will be further discussed hereinafter, are interconnected by a means of security bolt boxes  250  which attach the panels together to form a safe. Each of the panels  230 ,  240 ,  270 , and  280  include an outer face and an inner face. Opposing side panels  270  have security bolt boxes  250  attached thereto. The security bolt boxes  250  include bottom faces  252  and upstanding walls  254  to form a tray-like configuration. The upstanding panels  254  can be interconnected with the bottom face  252  or can be formed by a bending and forming operation as previously described. The opposing side panels  270  by means of anchor bolts (not shown) which extend through anchor bolt box apertures  256  provide with attachment bolt apertures  258  extending through the upstanding walls  254  for receiving attachment bolts (not shown) to attach opposing side panels  270  with top and bottom panels  230 ,  240  and back panel  280  to form a safe. Importantly, the upstanding side panels  254  of the security bolt box  250  are recessed from the forward and rearward edges of opposing side panels  270  to allow for positioning of rear panel  280  and front panel  121 . The security bolt boxes  250  are flush with the upper and lower edges of the opposing side panels  270 . The opposing side panels  270  as well as back panel  280  sit on bottom panel  240 . Likewise, top panel  230  sits on top of opposing side panels  270  and back panel  280 . The front panel  221  can be hingedly attached to one side panel  270 . 
   The panels shown in  FIGS. 6   a – 6   c  can be constructed in the same manner as previously disclosed herein. 
     FIG. 8  is a side view of two panels  300  positioned adjacent each other, each panel includes an outer surface  333  and an inner surface  334 , the inner surface  334  having a rabbet face  336 . These panels are identical to those illustrated in  FIG. 6   c . In the embodiments heretofore discussed, one panel  300  would be used to form the bottom of a safe, and one panel each would be used to form the side panels of a safe with another identical panel  300  being used to form the upper wall of the safe. The remaining open wall would accept a mounted pivotal door allowing access to the safe. In this further embodiment, such a safe as that illustrated in  FIG. 6   c  may be expanded using identical panels in addition to a reconfigured security bolt box and a filler block. 
   In  FIG. 8 , the two panels  300  are positioned adjacent each other, each having an identical interior rabbetted face  336 . A filler block  338  is dimensioned to snugly fit between the slotted gap  339  between the two rabbetted faces  336 . Filler block  338  is constructed in the same manner as panels  300  as heretofore previously discussed. A security bolt box  350  would then be secured to the two adjacent panels  300 , the security bolt box spanning the rabbetted faces  336  and the filler block  338  maintaining the filler block in position. In this configuration it can be seen that the seam  341  between adjacent panels  300  is not continuous from the exterior surface  333  of adjacent panels  300  to the interior of the safe. The filler block  338  serves to block the seam and prevents a would be safe cracker or robber from using such seam  341  as a means of ingress into the safe. 
     FIG. 9  is a cross sectional view of the safe  120  as illustrated in  FIG. 6   c  wherein Applicant&#39;s expandability capability has increased the volume of the safe by a factor of 4.  FIG. 9  presents a cross sectional view for better understanding. In  FIG. 9 , a series of identical panels  300  have been juxtaposed adjacent each other such that two panels  300  form the base  340  of the safe, two juxtaposed panels  300  form one side  370  of the safe, two juxtaposed panels  300  form the opposing side  370  of the safe and two juxtaposed panels  300  form the upper surface of the safe. In each instance, a filler block  338  is fit within the slot  339  formed by adjacent rabbetted surfaces  336  of adjacent panels  300  thereby interrupting and blocking the seam  341  formed between such adjacent panels  300 . A security bolt box  350  is then secured to the bottom, sides and top walls of the interior surface of the panels formed by the rabbetted face and the filler block and secured in place. In this manner, the security bolt box  350  secures the panels  300  and the filler block  338 . 
   In the cross section illustrated in  FIG. 9 , the depth of the safe, similar to that illustrated in  FIG. 6   c  has not been increased, rather the width and the height have been doubled to increase the volume of the safe by a factor of four. The rear wall would be assembled in the same manner as that described with respect to the bottom, top and side walls with the understanding that four panels  300  and associated filler blocks  338  would be required to provide a continuous rear wall with the side, top and bottom walls illustrated. The same would hold true for the front wall (not shown) and the incorporation in the front wall of a door means, hinge, handle and combination lock as illustrated in  FIG. 6   c.    
   Applicant&#39;s development of a manner in which to secure a double door safe, vault or bunker constructed of Applicant&#39;s modular panels or for conventional double door assemblies for safes, vaults or bunkers is first illustrated in  FIG. 10  which is a front view of a double door  400  for a safe, vault or bunker. Double door  400  comprises a first door  402  and a second door  404 , the doors being mounted adjacent each other in the wall  405  of a safe, vault or bunker. In the double door  400  illustrated in  FIG. 10 , the double doors  402  and  404  are formed by a plurality of panels  300  as described heretofore which allows for the construction of a safe, vault or bunker and concomitant doors thereof in situ. The doors are mounted at their outer edges  406  and  408  by hinge means  410  and  412  which would preferably be in the form of a piano hinge which extended the height of the double door  400 . Secured into one of the double doors would be a combination lock or keypad  24  of conventional construction which would engage or disengage a lock engaging member on the interior of said door, a handle means  23  as provided on the modular safes previously discussed, and a throw bolt wheel  414  which secures the first door  402  and the second door  404  in a locked and secured position and which allows for the unlocking of the first door and second door  402  and  404  respectively. 
     FIG. 11  is a rear view of the double door  400  as viewed from the interior of the safe, vault or bunker. First door  402  and second door  404  are defined by an outer edge  406  and  408  where the doors are hingeably mounted to the wall  405  of the safe, vault or bunker. The inner edges of the door  416  and  418  meet at seam  420  which bisects double door  400  from the upper edge  422  to the lower edge  424 . 
   Mounted on the rear surface  426  of first door  402  is a first longitudinal bolt channel  428  and a second longitudinal bolt channel  430 . First and second longitudinal bolt channels  428  and  430  are C-shaped sections as illustrated in  FIG. 14 . The C-shaped sections comprise an elongated planar base web  432  with two perpendicular side walls  434  and  436  depending from the same side of the elongated planar base web  432 . One of the perpendicular side walls,  434 , has a planar horizontal lip  438  parallel with the elongate planar base web  432  and oriented towards the opposing side wall  436 . 
   First longitudinal bolt channel  428  is positioned proximate to the vertical outer edge  406  of first door  402  with lip member  438  oriented so that it is extending towards the seam  420  formed between first door  402  and second door  404 . 
   Second longitudinal member  430  is positioned along the inner edge  416  of first door  402  which is the seam  420  formed between first door  402  and second door  404  with its lip member oriented towards the outer edge  406  of first door  402 . First and second longitudinal bolt channels  428  and  430  are secured to the inner surface  426  of first door  402  by a plurality of threaded fasteners or bolts  440  which are secured through elongated planar base web  432  into the panels  300  forming first door  402 . 
   First longitudinal bolt channel  428  has a plurality of fixed rods  442  or deadbolts secured to perpendicular side wall  436  and extending through apertures  444  in opposing perpendicular side wall  434 , the rods  442  or deadbolts extending beyond the outer edge  406  of first door  402 . 
   Second door  404  has a similar C-shaped first longitudinal bolt channel  450  positioned along its outer edge  408  with identical fixed rods  442  or dead bolts exending beyond the outer edge  408  of second door  404 . First longitudinal bolt channel  450  of second door  404  also has a plurality of apertures in perpendicular side wall  436  for receipt of movable throw bolts described hereafter when the door is in an unlocked and open position. First longitudinal bolt channel  450  of second door  404  is secured to second door  404  in a manner similar to that described with the longitudinal bolt channels of door  402 . 
   Second door  404  has a second C-shaped longitudinal bolt channel  454  ( FIG. 15 ) having a planar base web member  456 , two perpendicular side walls  458  and  460  extending to the same side of elongated planar base web  456 , however, second C-shaped bolt channel  454  of door  404  has a wider base web than longitudinal C-shaped bolt channels  428 ,  430 , and  450 . Second C-shaped bolt channel  454  of door  404  is secured to the rear face  462  of door  404  in a manner similar to the other C-shaped bolt channels  423 ,  430 , and  450 , however, second C-shaped bolt channel  454  of door  404  overlaps the seam  420  between doors  402  and  404 . 
   Perpendicular side walls  458  and  460  of second C-shaped bolt channel  454  of door  404  has at least one aligned aperture guide  464  formed therein for the passage of movable throw bolts as described hereafter. 
     FIG. 13  is a front planar view of the locking mechanism  430  which comprises a plurality of rod-shaped, horizontal throw bolts  472 , each of the rod-shaped, horizontal throw bolts  472  having a first end  474  being secured to a vertical throw bolt support bar  476 . At least one of the throw bolts  472  extends beyond support bar  476  and is engageable within an aperture of C-shaped channel. On the underside of at least one of the throw bolts  472  would be mounted a linear toothed gear  478  cooperative with a rotatable round toothed gear  480  mounted on door  404  between second C-shaped bolt channel  454  of door  404  and first C-shaped bolt channel  450  of door  404 . Round toothed gear  480  is mounted on a shaft  482  of the interior of door  404  which shaft extends through door  404  to the exterior of door  404  and on which is mounted the throw bolt wheel  414 . A lock engaging member actuable from said keypad  24  allows for the rotation or non-rotation of gear  480 . 
   In operation, with the double door  400  closed and in a locked position, one seeking entry into the safe, vault or bunker, would enter in the appropriate combination or code on the keypad  24 . The entering of the proper code or combination would cause a releasing mechanism to become unlocked on the interior surface of the double door opposite the throw bolt wheel  414 . The user would then rotate the throw bolt wheel  414  which in turn would engage linear toothed gear  478  on one of the throw bolts  472  by means of rounded tooth gear  480  such that all of the horizontal throw bolts  472  and support bar  476  would move away from seam  420  of double door  400  and become disengaged from second longitudinal bolt channel  430  on first door  402  and be withdrawn such that second end  475  of horizontal throw bolts  472  are positioned within second longitudinal C-shaped bolt channel  454  of second door  404 . The user would then engage the handle means  23  on first door  402  to open first door  402  and subsequently open second door  404  allowing access to the safe, vault or bunker through the opened double doors. In closing and securing the safe, vault or bunker, the aforementioned steps would be taken in reverse. First, door  404  would be closed and then door  402  would then be closed. The user would then engage the throw bolt wheel  414  and rotate it so that the horizontal throw bolts  472  would again extend through second C-shaped longitudinal bolt channel  454  of door  404 , across seam  420  formed between door  404  and door  402  and into second longitudinal C-shaped channel  430  on door  402 . The user would then enter an appropriate code on the keypad  24  which would again engage the locking device on the interior of door  404 . The horizontal throw bolts  472  are now in a locked engaging position and access to the safe, vault or bunker cannot be had without proceeding with the opening process as heretofore described. 
   This assembly illustrated allows for a minimum of four contact points for securing the double doors in a locked and secure position. Four contact points eliminate rattle in the doors by allowing more contact point pressure. The number of contact points can be increased by increasing the number of bolt channels on door  402 . The concomitant increase in number of bolt channels would require an increase in the length of the throw bolts and this would only be limited by the width of the door which would dictate the amount of room available for the throw bolt mechanism when the door was in the unlocked or unsecure position. It eliminates the need as required by the prior art for their to be vertical throw bolts on the interior of the double doors such that one of the doors could be opened, but the second door could not be opened until the user had reached inside and released the vertical throw bolts from their locked and secured position. The current assembly provides for security of the safe, vault of bunker with less mechanical operation. Still further, the securing means disclosed herein, allows for a safe, vault or bunker having a double door, to be erected or fabricated in situ because of the use of modular panels and the modularity of the locking mechanism. Still further, the locking and securing mechanism as disclosed herein can have application to a double door utilized in a safe vault or bunker of conventional construction, e.g. not of modular panels, without departing from the spirit and scope of the invention. 
     FIG. 16  is an inside view of a double door of conventional construction and not fabricated from the Applicant&#39;s proprietary panels. The locking mechanism would be installed in the same manner and operate in the same fashion as heretofore described. 
   While the present invention has been described with respect to the exemplary embodiments thereof, it will be recognized by those of ordinary skill in the art that many modifications or changes can be achieved without departing from the spirit and scope of the invention. Therefore it is manifestly intended that the invention be limited only by the scope of the claims and the equivalence thereof.
