The invention relates generally to the field of safes, and more particularly, is directed to a small, lightweight, sturdy safe suitable for home or office use.

The need to protect property and to provide for safe stor¬ age of valuables has been and continues to be an activity of considerable importance to civilized segments of society in an endeavor to develop reasonable safety measures for items of value, such as money, jewels, commercial papers and the like. In view of the great interest in the subject matter, it will be appreciated that literally hundreds of prior art devices have been developed by workers in this field in an effort to design storage facilities of adequate safety for the required purpose. Such prior, facilities have varied in size and complexity through an extremely wide range, of design parameters, depending upon the end result desired. For example, the United States government has designed, developed and constructed an enormous storage vault at Fort Knox within which to store and protect the nation's gold storage supply. At the other end of the scale, a school child can find adequate safety and peace of mind by storing his coins within a small, inexpensive, locked facility, for example a common piggy bank.

Between these two extremes, of course, prior workers have developed numerous more or less extensive, expensive and compli¬ cated constructions, for example the built-in vaults with massive vault doors which are. common in many banks. Wall safes and heavy steel floor safes are commonly employed in places of business, hotels and the like and numerous types of locked boxes and safes have been developed for home use. As is apparent from the fore¬ going, depending upon the value and the size of the items to be stored, more or less expensive and complicated safe and vault con¬ structions can be provided by utilizing known techniques. Des¬ pite the myriad of prior safe constructions which have in the past been produced, the need remains for an inexpensive, sturdy,

SUMMARY OF THE INVENTION

The present invention relates generally to the field of protective safes, and more particularly, is directed to a tamper resistant safe of relatively modest cost and size and which can be readily adapted for permanent use 'within a home, office or a small commercial establishment.

The present invention contemplates the use of a tamper resistant safe or strong box that is relatively inexpensive in ^" cost, which can be easily transported to the place of installa¬ tion and which can be readily secured in place in a short period of time by utilizing standard hand tools and without requiring skilled or trained mechanics for installation purposes.

The safe of the present invention includes a hollow, gener¬ ally rectangular enclosure or body which is fabricated of strong, tough, tamper resistant material of a type which can be bent, cut, welded or otherwise worked to a final desired configuration at reasonable cost. In a preferred embodiment, the safe body is fabricated of eleven U.S. gauge steel sheet which is cut, bent, welded and otherwise worked as necessary to provide a small, relatively inexpensive, extremely tough, tamper resistant safe body. The steel sheet is cut, bent ^*" _ulS Oth-e'rWise worked with conventional metal working machinery as necessary to provide a body of generally rectangular cross sectional configuration in¬ cluding an enlarged top opening for access purposes. Preferably, the top opening is defined both by a portion of the enclosure top and by a portion of one of the enclosure side walls immediate¬ ly adjacent to the top whereby an enlarged opening to provide easy access within the container is provided.

The enclosure or body is formed and designed about the opening in such a manner to provide grooves, flanges or other reinforcing constructions which, when taken in cooperation with the closure cover, provide reinforcement at every junction be¬ tween the cover and the container to thereby discourage tampering.

OMPI f _j , WIPO «_

_' A top cover or closure, which is generally L-shaped in cross sectional configuration, preferably is fabricated of a strong, decorative material such as stainless steel and, in cooperation with the grooves and flanges of the container, includes bent lips to provide a secure closure for the safe.

In the preferred embodiment, the top is L-shaped in con¬ figuration and includes a sliding leg and a locking leg in right angle orientation for safe closure and locking purposes. The locking leg slides horizontally within a pair of opposing tracks or grooves defined between the container top flanges and track strips and includes a locking leading edge or tongue to discour¬ age prying between the leading edge of the sliding leg and the rear marginal edge which defines the container opening. One or -ore key or other operated locks are mounted within the locking leg in position to secure the cover to a permanent construction component of the container when it is desired to lock the device.

By utilizing modern tooling processes and assembly line techniques, the elements comprising the novel tamper resistant safe can be rather inexpensively manufactured and assembled to thereby provide an extremely strong, workable, lightweight, tampe resistant safe at -a modest cost.

It is therefore an object of this present invention to provide an improved tamper resistant safe of the type set forth.

It is another object of the present invention to provide a novel tamper resistant safe that can be readily affixed to existing building construction members.

It is another object of the present invention to provide a novel tamper resistant safe that incorporated a heavy gauge steel body which is bent to the desired configuration to define a top opening and an enclosure cover that is a sliding fit within the body to lockably close the opening. _f

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

Although specific terms are used in the following des¬ cription for the sake of clarity, these terms -are intended to refer only to the particular structure of the invention select¬ ed for illustration in the drawings, and are not intended to define or limit the scope of the invention.

Referring now to the drawings, the tamper resistant safe 10 of the present invention is illustrated in Fig. 1 installed in a room, for example adjacent the corner formed by the room wall 40 and the room floor 42. T e safe 10 comprises generally an enclosure or container 12 formed with a front wall 14, a rear wall 16, a right side wall 18, a left side wall 20, a bot¬ tom 22 and a top 24 which components are formed to define an interior space 44 therewithin for valuable storage purposes. The top of the front wall 14 and the enclosure top wall 24 are cut or otherwise treated to define a top opening 46 to facili¬ tate the placement of valuables into the safe interior 44 and the easy extraction of the valuables from the safe interior when so desired. By forming the top opening in both the top wall 24 and front wall 14, an opening of greater size can be conveniently provided to improve access.

A top cover 26 is a sliding fit within a pair of hori¬ zontally spaced upper tracks 48, 50 which are provided imme¬ diately below flanges 62, 64 of the top 24 for safe closure purposes. As best seen in Figs. 2 and 3, the cover 26 is gener¬ ally L-shaped in configuration and comprises a sliding leg 28 which is integral with and oriented at ninety degrees from the locking leg 30. The cover sliding leg 28 is configured to selec¬ tively close that portion of the top opening 46 defined at the top of the container front wall 14 when it is desired to lock the safe to protect any valuables placed within the safe interior 44.

One or more locks 32, 34 may be conventionally mounted in the locking leg 30 in usual manner to extend interiorly sufficiently to allow the locking projections 52, 54 rotatively to engage in interior flage 72 of the enclosure 12 when it is desired to lock the safe.

It is contemplated that the safe 10 will be fabricated of generally modest dimensions so that the device will be light enough to be readily moved to any desired location for permanen installation.. For example, when it is desired to utilize the safe 10 -within a structure, such as a room of a house, an offic or a commercial establishment, the safe will first be placed in the desired permanent location, for example at the corner 56 of the room with the container bottom 22 adjacent to the room floo 42 and container back or rear wall 16 adjacent the room side wall 40. The safe can then be permanently secured in position by employing suitable fasteners through the bottom wall mountin openings 36 or any.desired combination thereof. When the room floor construction 42 is of concrete, it will be necessary firs to provide suitable openings in the concrete alignment with the bottom mounting openings 38. Then conventional expansion shields or similar devices can be employed to securely affix the safe 10 to the floor 42.

In cases where the floor 42 or the wall 40 is fabricated of the wooden construction members, then sturdy threaded mem¬ bers such as lag screws or other fastening devices can be em¬ ployed through the mounting openings 36 or 38 or combination thereof as may be required by the individual installation cir¬ cumstances. In plaster constructions, suitable expansion type bolts (not shown) should be employed. It is noteworthy that the fastening members (not illustrated) utilized through the mounting openings 36, 38 will be driven into the wall 40 or floor 42 construction from within the interior space 44 defined within the safe enclosure or container 12. Accordingly, after

the safe 10 has been secured in the desired position, and the cover 26 has been locked in position by utilizing the locks 32, 34 (Fig. 1) , then a would-be thief would be unable to re¬ move the fasteners (not illustrated) inasmuch as the heads of such fasteners will be fully protected within the locked en¬ closure and will not be subjec to access.

As best seen in Figs. 1 and 2, in a preferred enbodiment, the container top 24 can be punched, bent or otherwise treated to define an elongated slot 58 with a depending protective tongue 60 to thereby provide an opening for the insertion of planar members, such as money, securities, etc. (not illus¬ trated) into the safe interior 44 without the need to remove the cover 26. The top construction also includes a second de¬ pending tongue 66 for cover interlock as hereinafter more fully set forth.

Referring now to Figs. 4, 5, 6 and 7, the additional protective construction features about the safe closure will new be described. The container top 24 is bent to provide a pair of spaced, parallel flages 62, 64 which act to retain the cover 26 in a sliding fit and further serve to define the top marginal extent of the top opening 46. The left and right top flanges 62, 64 terminate rearwardly at the depending tongue 66, which tongue interacts with the depending leading edge 68 of the cover sliding leg 28 to prevent tampering. As best seen in Fig. 4, the cover leading edge 68 projects downwardly and under the depending second tongue 66 of the container top 24 to form a first tool resistant interlock 70 when the cover 26 is fully seated on the enclosure 12 in the closed and locked position.

Still referring to Fig. 4, it will be seen that the con- tainer front wall 14 terminates upwardly in an inwardly bent flange 72, which flange defines the lower extent of the top opening 46. By extending the top opening 46 downwardly into i

the; front wall 14, access to the container interior 44 is en¬ larged to facilitate insertion of valuables into or removal of valuables from the interior of the safe 10. The bent front flange 72 additionally serves as a strike plate or keeper upon which the locking projections 52, 54 can be turned to bear thereagainst in order to prevent unwanted removal of the cover 26 when a key 74 is inserted into a lock 32 or 34 and turned to lock the device.

To form the pair of upper tracks 48, 50 to receive the sliding leg 28 of the cover 26 in sliding engagement therein, a pair of spaced, bent, steel strips 76, 78 are spot welded or otherwise securely affixed respectively to a container side 18, 20 near the respective tops thereof. The tops of the strips 76 78 terminate below the bottoms of the flanges 62, 64. Each of the strips 76, 78 is medially horizontally bent to inwardly space the respective upper track sections 80, 82 from the adja¬ cent container side walls 18, 20 sufficiently to receive in sliding engagement the depending portions or lips 98, 100 of the sliding leg 28 therewithin when the cover is attached to the container. The respective base or lower track sections 84, 86 of the track strips 76, 78 respectively permanently affi directly to the interior sides of the container side walls 18, 20 in permanent, known manner such as by spot welding.

The front strips 88, 90 are affixed respectively to the container side walls 18, 20 forwardly of the track strips 76, 7 and may be arranged at right angles thereto through respective miter joints 92. The front strips 88, 90 are suitably medially bent to space their respective forward portions inwardly from the right and left side walls 18, 20 to form forwardly open re¬ cesses 94, 96 with the right and left side walls 18, 20. The recesses 94, 96 receive therein the side lip portions 106, 108 of the cover locking leg 30 when the cover 26 is fully seated on the enclosure 12 in the locked position.

Referring now to Fig, 3, it will be observed that the transverse marginal edges of the cover sliding leg 28 are in¬ wardly or downwardly bent to provide a pair of spaced, depending lips 98, 100. As illustrated in Fig. 5, the sliding leg lips 98, 100 fit within and slide within the recesses 102, 104 formed by spacing the respective upper track sections 80, 82 from the container side walls 18, 20. Thus it is .seen that a complete, interlocked, strong, sliding, top engagement is formed between the sliding leg 28 of the cover 26 and the top 24 of the enclosure or container 12. The spaced edge portions of the sliding leg 28 insert within and slide within the respec¬ tive right and left upper tracks 48, 50. Simultaneously, the depending lips 98, 100 insert within and slide within the re¬ cesses 102, 104 defined between the track strips 76, 78 and the container side walls 18, 20.

Thus it is seen that the container top construction over- fits and shields the transverse marginal edges and the rearward edge of the sliding leg 28 of the cover 26 at all locations wherein a would-be thief might attempt to insert a tool in an effort to pry the cover 26 loose from the enclosure 12. More specifically, the leading edge 68 of the slidng leg 26 is fully protected beneath the top depending tongue 66 at the first interlock 70. The right side of the cover 26 is fully protected by the positioning and strength of the right top flange 64. Similarly, the left marginal extent of the sliding leg 28 is fully protected by the positioning and strength of the top left flange 62 which overfits and acts to prevent un¬ authorized entry. The right and left track strips 76, 78 de¬ fine a sliding arrangement with the container top and sides to facilitate sliding engagement of the sliding leg 28 of the cover 26 therewithin in a manner to prevent tampering.

As illustrated best in Figs. 3 and 7, the side marginal edges of the cover locking leg 30 are inwardly bent at right

angles to form the respective rearwardly facing side lips 106, 108. The side lips 106, 108 slide respectively into the for¬ wardly open recesses 94, 96 defined by the fron strips 88, 90 to provide completely protected, enclosed, side closures when the cover 26 is fully seated and locked to cover the top opening 46.

The bottom edge of the locking leg 30 is similarly in¬ wardly bent at ninety degrees to form a strengthening and tam¬ per resisting flange 110 to furthe prevent unauthorized entry when the cover 26 is locked in position on the enclosure 12. As illustrated in Fig. 4, the bottom strengthening flange 110 stops against the front flange 72 which had been bent into the front wall 14. Preferably, the length of the offset 112 be¬ tween the front wall.14 and the front flange 72 equals approxi¬ mately the length of the cover strengthening flange 110 so that the strengthening flange 110 abuts tightly against the front flange 72 to form the second interlock 112 in a manner to pre¬ vent tampering or unauthorized entry at the bottom of the cover 26.

Although the invention has been described with a certain degree of particularity, it is understood that the present dis¬ closure has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the scope of the invention.
