[0001]    This is a Utility Patent Application filed for the invention by Johnny Edward Walker for a “Theft Deterrent Enclosure” that claims priority from co-pending U.S. Provisional Patent Application Ser. No. 61/180,148 filed May 21, 2009. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention relates generally to a new and improved tamper resistant enclosure. More particularly, this invention provides an enclosure for a cable service box that is easy for to service personnel to open and service but resistant to unauthorized access. 
         [0004]    2. Description of the Prior Art 
         [0005]    Prior art enclosures for protecting cable boxes and telephone lines have proven deficient in a number of respects. Cable television providers currently face many problems with the theft of components and other cable equipment that are mounted in open areas. In some areas, the theft of these types of components such as power supply boxes is a multi-million dollar industry. Cable providers face even more substantial losses of revenue through increased trouble calls, theft of services, theft of splitters, amplifiers, and signal leakage from cable boxes mounted to the exterior of residences. An unauthorized user may access the cable box of an authorized user and engage in signal splitting or other undesirable tampering. Components such as filters, taps, splitters, fittings and coaxial wire may also be stolen from these cable boxes and result in further losses to the cable provider. Such use not only results in lost revenue for the cable provider, but in addition may alienate the authorized user who endures reduced signal quality or service outages. 
         [0006]    Signal leakage also results in adverse safety considerations. The Federal Communications Commission (FCC) and other regulatory agencies have mandated for example that signal leakage be reduced due to the negative effects on emergency communications such as those involving police, fire, aircraft, ham radio, security agencies, television and radio. Signal leakage could possibly disable the communications of safety services or aeronautical navigation systems. Such signal leakage is especially pronounced where not only has cable theft occurred, but the unauthorized users have cut some wires, loosely replaced others, or used cheap after-market splitters. 
         [0007]    Enforcement after the fact is difficult for cable providers even though cable theft is a criminal offense in the United States under federal and state law. In theory, the federal Digital Millennium Copyright Act provides particularly stringent regulations against such behavior. However, in many cases, the only evidence left behind of such activities is in the possession of the valid users, and efforts to cut service to those utilizing splitters has an adverse effect on the valid user whose cable box has been accessed. Monitors have been utilized to detect theft and quickly address problems that occur, but these are expensive relative to their benefits. 
         [0008]    As a result of the above discussed problems, it is desirable to provide cable housing boxes that prevent entry without detriment to the existing services. Cable providers across the country generally use either pad locks or a round inset lock that can be drilled through or knocked out, such that the lock is merely spinning around in the box and never locking the box itself. The locks also typically use a relatively expensive standardized key that has long since been duplicated to gain entrance to the enclosures. Due to the large number of enclosures and the costs of the locks, providers are reluctant to change the keys often. In addition, the enclosures typically have a housing that is easy to pry open or drill into and, thus, generally easy to break into. This leads to a situation where the enclosures are repeatedly vandalized and their contents accessed. The insecure nature of the prior art enclosures results in increased labor, material, repair and maintenance expenses and a culture of illegal access. 
         [0009]    Prior art publications and patents have not addressed the above problems in a satisfactory manner. Many of the existing enclosures require substantial bending of cables entering or exiting the cable box, are difficult for authorized users such as technicians to access, or are prohibitively expensive to manufacture. 
         [0010]    Therefore, what is needed is a theft deterrent cable housing box that provides easy access for an authorized user to the inside of the box while minimizing the likelihood of unauthorized access. It would further be desirable for such a device to be of relatively low cost and have easy access for cables passing to and from the box. 
       BRIEF SUMMARY OF THE INVENTION 
       [0011]    The present invention provides a cable housing device for preventing cable box theft, minimizing signal leakage, reducing trouble calls, and providing an increase in customers. The device includes a double-locking mechanism that is relatively simple for authorized users having the proper tools to access. The device opens such that authorized users can easily work within the device once it is opened. In contrast, unauthorized users are substantially prevented from accessing the interior of the device. The device is of relatively low cost and requires minimal bending of cables entering into the interior of the box. The device is also easily mounted in any location in which such cable housing boxes are usually located. 
         [0012]    More particularly, an embodiment of the present invention is directed toward a theft deterrent enclosure that has a two-piece housing. A first lock mechanism is mounted in a lock opening on the housing such that the first lock mechanism blocks the lock opening. The first lock mechanism can be removed from the lock opening using a key which mates with the first lock mechanism. A second lock mechanism is positioned in an interior of the enclosure such that the second lock mechanism is aligned with the lock opening and can be engaged with an elongated security keyed tool inserted through the lock opening. 
         [0013]    The enclosure is preferably constructed from a door assembly having a door housing and a wrapper assembly having a wrapper housing that mates with the door assembly to form the enclosure. The first lock mechanism includes a key lock cylinder that is mounted in a lock opening in the door housing such that a tumbler in the key lock cylinder blocks the lock opening when the tumbler is locked in the key lock cylinder. The second lock mechanism includes a keyed interface that is mounted on the door housing such that the keyed interface engages a fastener, such as an offset nut, lock plate or compression latch, which secures the door assembly and the wrapper assembly in a closed position when the keyed interface is engaged with the security key tool. The keyed interface is positioned on an interior side of the enclosure opposite and aligned with the lock opening. A sleeve guide is positioned inside the enclosure, and in alignment with the lock opening and keyed interface, that guides the security keyed tool toward the keyed screw when the keyed tool is inserted through the lock opening. 
         [0014]    The theft deterrent enclosure can be opened from a locked position by engaging the key lock cylinder with a key, removing the key lock cylinder from the lock opening, inserting a security keyed tool adapted to engage the keyed interface through the lock opening and disengaging the fastener. 
         [0015]    Another embodiment of the invention is directed toward a device that includes a body having three sides and a lid having three sides. A pair of hinge blocks having set screws are mounted on the lid so that they can engage a hinge pin mounted on the body to removably and pivotally mount the lid on the body. When the lid pivots to engage the body in a closed position, the body and lid together form a box having a generally cubed or rectangular shape and six sides. 
         [0016]    A first locking assembly is positioned on the lid that has a tumbler that can be unlocked and removed to expose an aperture in the lid. The locking assembly preferably has an anti-spin design and is made of stainless steel. As a result, an undesired entrant would require a long period of time and multiple drill bits to drill through the tumbler. The locking assembly is constructed so that even when the tumbler is removed in an unauthorized manner, steel fingers inside the lock obstruct the opening such that access to a second locking assembly is restricted. 
         [0017]    The second locking assembly includes a guide bracket attached to the lid that has an aperture, a threaded fastener located in the guide bracket aperture, and a subassembly attached to the body that has a recessed portion that is threaded to receive the threaded fastener. The aperture and the recessed portion are aligned when the lid is in the closed position so that they define a channel aligned with the aperture in the lid. Thus, once the tumbler of the first locking mechanism is removed, a tool that is shaped and sized to fit through the channel and engage the fastener can be inserted through the lid aperture and channel to engage the fastener and unlock or lock the box. The fastener can use a lock plate, compression latch or threaded nut to securely hold the lid and wrapper together. 
         [0018]    First and second locking tabs are preferably located on opposing ends of one side of the lid and first and second members are attached to opposing sides of the body. The members are shaped to receive the locking tabs when the lid is closed. These tabs and members secure the box housing from being bent or pried open from the outside. In addition, in conjunction with a hidden internal hinge connection, the tabs and member make the box very difficult to pry open or drill into.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0040]      FIGS. 1(   a - d ) are top ( a ), isometric ( b ), side ( c ) and front views ( d ) of a preferred embodiment  1  of the present invention. The unique locking mechanisms and robust housing of the enclosure  1  shown reduce the risk of authorized access to the contents of the enclosure  1 . The preferred embodiment shown in the figures consists of a wrapper assembly  2  and a door assembly  4 . The wrapper assembly  2  includes a wrapper housing  6  and the door assembly  4  includes a door housing  20  which serve to mount the components of the assemblies  2  and  4  and protect the contents of the enclosure  1 . The wrapper housing  6  and the door housing  20  are preferably constructed from stainless steel. 
         [0041]    The door assembly  4  is pivotally connected to the wrapper assembly  2  with the pivotal attachment consisting of a pin  18  having two ends  8  affixed to the wrapper assembly  2  and a pair of hinge blocks  15  attached to the top and bottom of the door assembly. The hinge blocks  15  have slots that are dimensioned to receive the pin  18 . Once the pin  18  is inserted into the slots of the hinge blocks  15 , set screws  19  are inserted into threaded openings in the hinge blocks  15  to enclose the pin  18  within the hinge blocks  15  and pivotally and firmly secure the wrapper assembly  2  to the door assembly  4 . The pin  18  is preferably welded to the wrapper assembly  2 . To mount the door assembly  4  on the wrapper assembly  2 , the pin  18  is inserted in the slits of the hinge blocks  15  and the set screws  19  screwed into enclose the pin  18  in the slits. 
         [0042]    The enclosure  1  shown in the illustration is adapted to receive a cable from a cable service provider and provide a customer cable access at a customer location. Thus, the wrapper housing  6  has a lower opening  50  that is sized to receive the incoming cable from the cable service provider. The wrapper housing  6  also has an upper opening  52  that is adapted to provide access to the customer side cable. In the embodiment shown, the lower opening  50  is 1.375 in diameter and the upper opening  52  is 2.438 in diameter. The wrapper housing  6  also has attachment openings  54  that are adapted to receive screws used to mount the wrapper assembly  2  on a surface such as a wall or pole. 
         [0043]    The door housing  20  of the enclosure  1  is preferably a U-shaped stainless steel metal member. The door housing  20  is used to mount the components of the door assembly  4  and protect the contents of the enclosure. The door housing  20  has a lock opening  56  that is dimensioned and positioned to receive a key lock cylinder  30  which is held in place against the door housing  20  with a lock cylinder nut  46 . The key lock cylinder  30  can be a single unit that mates directly with the housing or a removable key cylinder in a separate lock sleeve that couples with the housing. 
         [0044]    A small offset bar  10  and large offset bar  12  are attached to the wrapper housing  6 . The small angles  22  of the door assembly  4  function in connection with the large  12  and small offset  10  bars of the wrapper assembly  2  to properly position the door assembly  4  with respect to the wrapper assembly  2  when the enclosure  1  is closed. The angles  22  and offsets  10  and  12  also function to brace the door assembly  4  and prevent it from moving with respect to the wrapper assembly  2 , or being pried apart, when the enclosure  1  is closed and locked. The angles  22  and offsets  10  and  12  are preferably constructed from bent stainless steel. 
         [0045]    A pair of flat bars  16  is also welded to the wrapper housing  6 . The flat bars  16  serve to brace the wrapper assembly  2  and door assembly  4  when the enclosure is locked. The wrapper assembly  2  flat bars  16  have been positioned between the wrapper housing  6  and the hinge pin  18 . Positioning the flat bars  16  in this manner further reinforces the hinge pin  18  and enclosure  1 . 
         [0046]    A U-bracket  36  has two legs  40  and  42  and is mounted on the door housing  20 . The U-bracket  36  is preferably welded to the door housing  20  but may be attached in any suitable manner. A compression latch is formed from a pair of locking arms  21  coupled to a spring biased pin  23  that has a security keyed shaft head  28 . The security keyed shaft head  28  is engaged through the lock opening with a security keyed tool once the key lock cylinder  30  has been removed. When the spring biased pin  23  is pressed with the security keyed tool and rotated with the door assembly  4  in a closed position with respect to the wrapper assembly  2 , the locking arms  21  engage or disengage a pair of mating projections  27  mounted on the wrapper housing  6 , preferably by welding. The mating projections  27  and locking arms  21  of the compression latch securely hold the door assembly  4  and wrapper assembly  2  in the closed position when engaged. 
         [0047]    Referring to  FIGS. 2(   a - d ), mechanical drawings of a top ( a ), bottom ( b ), right side isometric ( c ) and left side isometric ( d ) views of a tamper resistant enclosure  101  constructed in accordance with another embodiment of the present invention are shown. The individual parts of the preferred enclosure  101  of  FIGS. 2(   a - d ) are shown in  FIGS. 3-10  and the same reference numbers refer to the same parts throughout  FIGS. 3-10 . 
         [0048]    Like the embodiment of  FIG. 1 , the embodiment shown in  FIG. 2  consists of a wrapper assembly  102 ,  FIG. 3 , and a door assembly  104 ,  FIG. 4 . The wrapper assembly  102  includes a wrapper housing  106 ,  FIG. 5 , and the door assembly  104  includes a door housing  120 ,  FIG. 7 , which serve to mount the components of the assemblies  102  and  104  and protect the contents of the enclosure  101 . The wrapper housing  106  and the door housing  120  are again preferably constructed from stainless steel. 
         [0049]    In contrast to the embodiment of  FIG. 1 , the door assembly  104  of  FIG. 2  is pivotally connected to the wrapper assembly  102  with a hinge pin  108  and a hinge tube  118 ,  FIG. 9 . The hinge tube  118  is preferably welded to the door assembly  104  housing  120 . To mount the door assembly  104  on the wrapper assembly  102 , the hinge pin  108  is inserted in the hinge tube  118 , the wrapper assembly  102  moved into position with respect to the door assembly  104 , and the ends of the hinge pin  108  welded to the wrapper assembly  104  housing  106  to permanently mount the door assembly  104  on the wrapper assembly  102 . The hinge pin  108  and tube  118  are preferably constructed from stainless steel. The hinge tube  118  has an inner diameter slightly greater than the diameter of the pin  108  so as to engage the pin  108  but freely accommodate rotation of the pin  108  to open and close the door assembly  104 . The hinge pin  108  and tube  118  are preferably attached by welding to the interior surfaces of the wrapper  106  and door housing  120  so that their attachment points are hidden from view to an observer on the outside of the enclosure  101  when the door assembly  104  is closed, thereby rendering the hinge mechanism substantially impossible to drill through or pry open. 
         [0050]    The enclosure  101  shown in the illustration is adapted to receive a cable from a cable service provider and provide a customer cable access at a customer location. Thus, the wrapper housing  106  has a lower opening  150  that is sized to receive the incoming cable from the cable service provider. The wrapper housing  106  also has an upper opening  152  that is adapted to provide access to the customer side cable. The wrapper housing  106  also has attachment openings  154  that are adapted to receive screws used to mount the wrapper assembly  102  on a surface such as a wall or pole. 
         [0051]    An alternative wrapper housing  188  is shown in  FIG. 16  that has a square shaped access opening  190  that can be used to mount the wrapper housing  188 . The enclosure  101  shown is designed and dimensioned to contain the standard components required for providing cable service. However, the dimensions of the openings  150  and  152  and the enclosure housing  106  and  120  can easily be altered to the requirements of any particular application as desired while still retaining the beneficial aspects of the design. 
         [0052]    Yet another alternative wrapper housing  200  is shown in  FIG. 17 . The wrapper housing has a series of access holes  202  formed in the bottom of the wrapper housing  200  that allow cable providers to provide access to the box to other service providers such as telephone companies. Barrel connectors connected to the appropriate lines are placed inside the access holes  202  so other providers can gain access to the needed services, but not the inside of the enclosure. This prevents the regrettable, but not uncommon, practice of competitive service providers tearing up competitors services so that customers will consider the new providers service. The present invention keeps third party service providers out of the enclosure while providing access to the service. The wrapper housing  200  of  FIG. 17  also differs from the previously discussed embodiments in that it has an enlarged opening  204  in the back and bottom of the housing. This allows a cable tap to be inserted through the back of the enclosure box which minimizes the need for splicing and resplicing. 
         [0053]    The door housing  120  of the enclosure  101  is preferably a U-shaped stainless steel metal member,  FIG. 7 . The door housing  120  is used to mount the components of the door assembly  104  and protect the contents of the enclosure. The door housing  120  has a lock opening  156  that is dimensioned and positioned to receive a key lock cylinder  130  which is held in place against the door housing  120  with a lock cylinder nut  146 ,  FIG. 10 . The key lock cylinder  130  can be a single unit that mates directly with the housing or a removable key cylinder in a separate lock sleeve that couples with the housing. 
         [0054]    A small offset bar  110  and large offset bar  112 ,  FIG. 6 , are attached to the wrapper housing  106 . The small angles  122 ,  FIG. 6 , of the door assembly  104  function in connection with the large  112  and small offset  110  bars of the wrapper assembly  102  to properly position the door assembly  104  with respect to the wrapper assembly  102  when the enclosure  101  is closed. The angles  122  and offsets  110  and  112  also function to brace the door assembly  104  and prevent it from moving with respect to the wrapper assembly  102 , or being pried apart, when the enclosure  101  is closed and locked. 
         [0055]    A pair of flat bars  116 ,  FIG. 6 , is also welded to the wrapper housing  106 . The flat bars  116  also serve to further brace the wrapper assembly  102  and door assembly  104  when the enclosure is locked. An alternative embodiment of the wrapper assembly is shown in  FIG. 18 . The wrapper assembly  310  differs from the wrapper assembly  102  of  FIG. 2  in that the flat bars  312  have been positioned between the wrapper body  314  and the hinge  316 . Positioning the flat bars  312  in this manner further reinforces the hinge  316  and enclosure. 
         [0056]    The U-bracket  136 ,  FIG. 8 , has two legs  140  and  142  and is mounted on the door housing  120 . One leg  142  of the U-bracket  136  has an opening or aperture that is used to mount the lock guide sleeve  126  to the door housing  120 . The other leg  140  of the U-bracket  136  has an opening that receives a special keyed lock screw  128 ,  FIG. 8 , which has a head that is designed to mate with a similarly keyed screw driver  127 . A screw retainer washer  132  holds the keyed lock screw  128  on the bracket leg  140 . The keyed lock screw  128  mates with an offset nut  114  which serves to firmly couple the door assembly  104  to the wrapper assembly  102  when the enclosure is locked as described in more detail herein. While a U-bracket  136  is used in the embodiment shown to mount the lock screw  128  and guide sleeve  126 , alternative means such as individual mounts can be used. 
         [0057]    To open the enclosure  101 , a user must first remove the key lock cylinder  130  from the lock opening  156  using a corresponding key. Once the lock in the key lock cylinder  130  is released, the key lock cylinder  130  is removed from the opening in the door housing  120 . However, once the key lock cylinder  130  is removed, the door assembly is still firmly held against the wrapper assembly by the keyed lock screws  28  engagement with the offset nut  114  which is mounted on the wrapper assembly  102 . To open the enclosure, the user must remove the keyed lock screw  128  after opening the key lock cylinder  130 . Thus, if the key lock cylinder  130  is removed by an unauthorized user, the enclosure  101  will still be locked and the second locking means will not be visible. 
         [0058]    The lock guide sleeve  126 ,  FIG. 8 , is used to guide a keyed screw driver to a special lock screw  128  so that the keyed screw driver can be inserted through the lock opening and the lock sleeve guide  126  to engage the special keyed lock screw  128  which has a head that is designed to mate with a similarly keyed screw driver. The keyed screw  128  can be easily altered and replaced to foil dedicated violators that obtain any particular keyed tool. 
         [0059]      FIGS. 11(   a - d ) illustrate the opening and closing of a cable housing device constructed in accordance with an embodiment of the present invention. The enclosure  160  consists of a body  162  and a lid  164  which are pivotally attached by a hinge  166 .  FIG. 11(   a ) shows a top view of the enclosure  160  in a closed position with the lid  164  coupled to the body  162  by the first  168  and second  170  locking mechanisms.  FIG. 11(   b ) shows a top view of the enclosure  160  in a ⅓rd open position with the lid  164  pivoting with respect to the body  162  on the hinge  166  and the first  168  and second  170  locking mechanisms unlocked.  FIG. 11(   c ) shows the enclosure  160  in a ⅔rds open position.  FIG. 11(   d ) shows the enclosure  160  in the fully open position which allows complete access to the components in the body  162  and positions the locking mechanisms  168  and  170  out of the way. 
         [0060]    Referring now to  FIGS. 12-15 , another embodiment of the present invention is shown. The device  210  includes a body  212  having first, second and third sides  214 ,  216 ,  218 . In the embodiment shown, the first and third sides  214 ,  218  extend perpendicular from opposing ends  220 ,  222  of the second side  216 . The three sides may be integrally formed from a single material and bent into shape, or may be formed separately and attached by welding for example. 
         [0061]    The device further includes a lid  224  having first, second and third sides  226 ,  228 ,  230 . The first and third sides  226 ,  230  extend perpendicular from opposing ends  232 ,  234  of the second side  228 . The lid  224  in various embodiments generally has smaller dimensions than the body  212  but may be substantially similar in shape and size such that together they form a box having six sides, the second side  228  of the lid  224  opposing the second side  216  of the base  212  when the box is in a closed position. 
         [0062]    The lid  224  is pivotally attached to the base  212 , with the pivotal attachment consisting of a pin  236  having two ends  238  affixed to the first and third sides  214 ,  218  of the body  212 , and a pair of hinge blocks  215  attached to the top and bottom of the first side  226  of the lid  224 . The hinge blocks  215  have slots  217  that are dimensioned to receive the pin  236 . Once the pin is inserted into the slots  217  of the hinge blocks  215 , set screws  219  are inserted into the threaded openings  221  in the hinge blocks  215  to enclose the pin  213  within the hinge blocks and pivotally and firmly secure the lid  224  to the base  212 . The use of hinge blocks  215  to mount the lid  224  on the base  212  may be preferred over the welded construction of  FIG. 2  in that it allows the lid  224  to be easily removed from the base  212  for maintenance or replacement in the field without the need for welding equipment. 
         [0063]    In the embodiment of  FIGS. 12-15 , the second side  228  of the lid  224  may also be referred to as the front  228 , or face  228 , of the device  210 . The first and third sides  214 ,  218  of the body  212  may also be referred to as the top  214  and bottom  218  of the device  210  respectively. In alternative embodiments, the front, top and bottom of the device  210  may be configured differently and the references herein with respect to these terms is not intended as limiting but merely as locational references to assist the reader. 
         [0064]    In manner similar to the embodiment of  FIG. 2 , a first locking mechanism  244  is positioned on the second side  228  of the lid  224 . The first locking mechanism  244  has an anti-spin design and includes a first locking mechanism  244  with a removable tumbler centrally located to the locking mechanism  244 . The tumbler is removable from the lock  244  when it is turned with a tumbler key provided to a user as discussed above. The tumbler key is preferably a specially made key that is intended for use only with the lock  244  or others of similar design. Upon removal of the tumbler from the locking mechanism  244 , an aperture is formed in the second side  228  of the lid  224  that permits access by a user to the inside of the closed box  210 . In an alternative embodiment, the first locking assembly  244  further can include steel fingers positioned inside the first locking mechanism that engage when the tumbler of the locking mechanism  244  has been improperly removed to make unauthorized access to the box much more difficult. 
         [0065]    A second locking mechanism  252  provides additional protection to improper opening of the box. The second locking mechanism  252  includes a guide bracket  254  attached to the third side  230  of the lid  224 . The guide bracket  254  may be integrally formed with the third side  230  of the lid  224 , but otherwise is attached to the lid  224  by means such as welding or equivalents well known in the art. The guide bracket  254  has a base  253  attached to the lid  224  and two arms  255  extending from the third side  230  of the lid  224 , each arm  255  has an aperture substantially aligned with the aperture in the second side  228  of the lid  224  when the lid  224  is in a closed position. 
         [0066]    A threaded fastener  258  is positioned in one the arms  255  of the guide bracket  254 . In the embodiment shown, the fastener  258  consists of a stainless steel specialty screw  258  having a head  260  facing the aperture in the second side  228  of the lid  224 , but various equivalent fasteners  258  may be substituted. The head  260  of the fastener  258  is shaped and sized to receive a special tool provided to the user as discussed above. The user may insert the special tool through the aperture in the second side  228  of the lid  224  after properly removing the tumbler from the locking mechanism  244  and engage the screw  258  to lock or unlock the second locking assembly in place on a subassembly  262  attached to the second side  216  of the body  212  and having a recessed portion threaded to receive the threaded fastener  258  or specialty screw  258 . The recessed portion in embodiments as shown is generally aligned with the aperture of the guide bracket  254 . 
         [0067]    A pair of locking tabs  266  is located on opposing ends of the second side  228  of the lid  224 . A pair of mating grove members  274  is attached to the first and third sides  214 ,  218  of the body  212  that define grooves  278 . The mating groove members  274  are shaped so as to receive the locking tabs  266  within the defined grooves  278  when the lid  224  is in a closed position with respect to the body  212 . This combination further secures the device  210  from being flexed, bent or otherwise pried open from the top or from the bottom of the outside of the device  210 , as such activities merely reinforce the positioning of the tabs  266  within the grooves  278 . 
         [0068]      FIGS. 19(   a - d ) are illustrations of a top ( a ), front ( b ), isometric ( c ) and side ( d ) views of an embodiment of the present invention adapted to be mounted on a pedestal  320  secured to the ground. The pedestal  320  is attached to the enclosure body  322  with protrusions  324  on the body that mate with shaped openings  325  on the pedestal. To attach the body  322  to the pedestal  324 , the protrusions  324  are inserted into the openings  325  and the body  322  moved right with respect to the pedestal  324  so that the protrusions  324  engage the openings  325  thereby holding the enclosure together. The pedestal  320  is secured to the ground with augers  326  having retaining washers  328  that grasp the ground. 
         [0069]    The embodiment of  FIGS. 19(   a - d ) uses a two lock system modified to accommodate the lid on a pedestal mounted enclosure body. To open the enclosure, the lock cylinder  330  is removed from the lock opening  332  in the same manner as described above. Once the lock cylinder  330  is removed, the keyed head  334  of the threaded shaft  336  of the second lock mechanism can be accessed through the lock opening  332  as before. However, in this embodiment, the second lock mechanism uses a lock plate  338  as shown in  FIGS. 20(   a ) and ( b ). The keyed threaded shaft  336  is mounted on two guide plates  342  connected to the enclosure body  322 . Rotation of the keyed threaded shaft  336  causes a lock plate  338  mounted on the shaft  336  between the guide plates  342  to move forward and backward and engage and disengage a locking slot  340  formed in the front of the pedestal  320 . Once the lock plate  338  is disengaged from the lock slot  340 , the protrusions  324  can be disengaged from the openings  325  and the body  322  removed from the pedestal  320 . Since the embodiment of  FIGS. 19 and 20  is operated in the substantially the same manner as the previously discussed embodiments, it can be operated by personnel in the same manner, with the same tool, without much regard to the particular construction of the lock assembly. 
         [0070]    It is to be understood that the present invention is not explicitly limited to the embodiment illustrated in the detailed description given above. Various changes and modifications may be made to Theft Deterrent Enclosure without departing from the spirit and scope of the invention as defined in the following claim.

Summary:
A theft deterrent enclosure that eliminates unauthorized access is disclosed. The enclosure includes a door assembly having three sides and a wrapper assembly having three sides that mate to form a lockable enclosure. A key lock cylinder is mounted in a lock opening of the door assembly such that it blocks the lock opening in a locked position. A keyed interface operates a fastener, such as a compression latch, threaded coupling or lock plate, which is mounted on the door assembly such that the fastener secures the door assembly and the wrapper assembly in a closed position. The keyed interface is positioned on an interior side of the enclosure that is opposite and aligned with the lock opening. A guide sleeve is positioned inside the enclosure that guides a security keyed tool inserted through the lock opening toward the keyed interface. The theft deterrent enclosure can only be opened from a locked position by engaging the key lock cylinder with a key, removing the key lock cylinder tumbler, inserting the security keyed tool adapted to engage the keyed interface through the lock opening and disengaging the fastener.
