Abstract:
A valuables safe incorporates a money slot that is both inaccessible and out of sight during periods when it is not desired to use the money slot, for example during off-hours in a business. The money slot is quickly made both accessible and visible by opening the safe and repositioning one element.

Description:
BACKGROUND OF THE INVENTION 
     It is often desired by the owners of businesses, etc., to insert money into a safe without going to the trouble of opening that safe. The problem, however, is that safes having money slots therein are relatively accessible by burglars. Furthermore, such safes typically will not be approved by underwriters. 
     SUMMARY OF THE INVENTION 
     It has now been discovered that an existing safe may be modified in a low-cost manner such as to provide a money slot therein. Then, the business person can easily insert money into the safe at various times during a working day. After the working day, the safe is opened and a simple procedure is followed whereby the money slot is rendered inaccessible and not visible to a burglar. The safe is then closed while the money slot is inaccessible and not visible. 
     The result is that a safe is provided which has the convenience of a money slot, but the safety of a safe not having a money slot. This result is achieved with an extremely small percentage increase in the manufacturing cost of the safe.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention may be incorporated in different types of safes, for example sliding-door safes and hinged-door safes, and any liftout-door safes. In the safe shown in the present application, the door is of the sliding type. 
     Reference is made to my prior U.S. Pat. No. 4,850,287 for Safe with Double Sliding Door, and U. S. Pat. No. 4,712,490, for Safe Said patents are hereby incorporated by reference herein. 
     The invention may be incorporated in safes in which the main bodies of two doors, one such door being either hinged or sliding, are in the same plane when the safe is in closed condition. In the present preferred embodiment, however, the main bodies of the two doors are in different planes when the safe is in closed condition. 
     Referring to FIGS. 1 and 2, the upper end portion of a safe body is indicated at 10. This is a strong rectangular or square frame having four strong sides 11,12,13 and 14, from which extend downwardly the sidewalls 15 of the safe. 
     Provided in parallel relationship within the access . opening of the safe, just below opposed frame sides 11 and 13, are strong support bars 17.- These are strongly welded or otherwise secured to the sidewalls 15, being mirror images of each other about a vertical central plane that is parallel to frame sides 11 and 13. Support bars 17 have upper horizontal supporting surfaces 18 for sliding support of first and second safe-door portions 21 and 22, respectively. The regions of such door portions that ride on supporting surfaces 18 are preferably provided with friction-reducing synthetic resin channels 24 and 25. 
     Stated more specifically, the first door portion 21 is a large and strong steel door plate having an edge 26 that, when the safe is closed, is maintained beneath an overhanging ledge 27 (FIG. 2). Ledge 27 is formed on a bar that is fixedly provided on a sidewall 15. To open and remove the door portion 21, it is slid to the right as viewed in FIG. 2 until edge 26 is no longer beneath ledge 27, following which a handle 28 is lifted to remove such door portion from the access opening. 
     A lock mechanism 30 (FIG. 2) is mounted beneath door portion 21, and a dial means 31 is mounted above such door portion, so as to selectively prevent sliding of the door portion 21 and thus maintain it in closed condition. The lock 30 has a bolt adapted to extend until it is adjacent the left end (FIG. 1) of a rigidly-mounted bar 32, the result being that when the bolt is in extended condition the door portion 21 may not be shifted to the right from beneath the ledge 27. When, however, the lock is operated to retract the bolt, such sliding may occur. The illustrated bar 32 has a bore 33 therein which forms part of a relocking mechanism preferably associated with the locking mechanism. Reference is made to my co-pending patent application Ser. No. 839,834, filed on even date herewith, for a Burglar-Resistant Lock-Operating Construction for Safes. Said application, which describes elements 30,31 and the relockers, is hereby incorporated by reference herein. 
     Proceeding next to the description of the second door portion 22, this also comprises a strong steel plate, numbered 36. Plate 36 has slide and hold-down plates 37 welded to the undersides of opposite portions thereof. As shown at the upper right in FIG. 1, the plates 37 extend outwardly from edges of plate 36 and (as previously stated) have synthetic resin channels 25 thereon for a minimization of friction. 
     As shown in FIG. 2, the left and right ends of each plate 37 are spaced or indented inwardly from the ends (left and right edges as shown in FIG. 2) of plate 36. The amount of this indenting is sufficient that, regardless of which way the second door portion 22 is turned, the right edge (FIG. 2) of the first door portion 21 may slide beneath an edge of the plate 36. Regardless of what edge of steel plate 36 the first door portion 21 slides beneath, that edge cooperates with ledge 27 to prevent opening of the entire door means until the lock mechanism 30,31 is operated and the bolt retracted. 
     Horizontal bars 38 are welded to frame sides 11 and 13 immediately beneath frame side 14, projecting outwardly therefrom as shown in FIG. 1. These bars 38 act as hold-down bars, and also fill in the gaps between opposed portions of plate 36 and the vertical inner surfaces of frame sides 11 and 13. It is emphasized that there are two such bars 38, one on the inner surface of each frame side 11 or 13, the bars being mirror images of each other about the above-specified plane. The plates 37 are likewise mirror images of each other about such plane. 
     A money-insertion opening, which is preferably a slot 42 that extends perpendicularly to the direction of sliding of door portions 21,22, is provided in plate 36 as shown in all figures. An anti-fishing sheet 43 is welded beneath slot 42 as shown at the right in FIG. 2, the lower edge of such sheet 43 being provided with large angular teeth. The ends of sheet 43 are welded to ears 44 that extend downwardly from plate 36. Sheet 43 substantially prevents persons from fishing anything out of the slot 42 even when the safe is in the money-insertion condition of FIGS. 1-3, inclusive. 
     The slot 42 (or other money-insertion opening) is disposed in such position on plate 36 that it will be accessible to the user for insertion of money therethrough when the second door portion 22 (including plate 36) is in the position of FIGS. 1-3, inclusive. The slot position is also such that 180-degree rotation of the door portion 22 about a vertical axis will cause slot 42 to be beneath frame side 14 when the safe is closed, reference being made to FIG. 4. Thus, when the parts are in the FIG. 4 positions, the slot 42 is not only inaccessible but is concealed so that the burglar does not even know it is there. 
     The frame side 14 is wide in comparison to the other frame sides, so as to overhang in close-fitting relationship a major portion of the plate 36. 
     In the preferred embodiment, money slot 42 is on one side of the center line of plate 36, thus achieving the relationship illustrated in FIGS. 3 and 4, the money slot either being exposed, or hidden and inaccessible, depending upon which way the second door portion 22 is oriented. 
     DESCRIPTION OF THE METHOD 
     When the owner of (for example) a small business wishes to have the money slot 42 in exposed and usable condition, he or she orients the door elements 21,22 in the positions of FIGS. 1-3, inclusive. Firstly, the second door portion 22 is slid to the right along upper support surfaces 18 until it is inserted far beneath the overhanging frame side 14. At this time, the outer edges of plates 37 are beneath bars 38. Then, such owner grasps the handle 28 and inserts the right edge (FIGS. 1 and 2) of first door portion 21 beneath the left edge of second door portion 22. At the same time, the door portion 21 is pivoted downwardly until it rests on surfaces 18. 
     As the next step, first door portion 21 is slid to the left until edge 26 thereof is beneath ledge 27 (FIG. 2). Thereafter, the lock means 30,31 is operated to cause the lockbolt to extend, thus preventing door portion 21 from shifting to the right. 
     The second door portion 22 can then shift somewhat toward and away from first door portion 21, but not sufficiently far that the second door portion 22 gets out from beneath overhanging frame side 14, and not sufficiently far that the first door portion 21 does not have its right edge (FIG. 2) beneath the outer edge (left in FIG. 2) of second door portion 22. The bars 38 cooperate in the locking action, because they hold down plates 37 which in turn hold down plate 36. 
     Thus, in accordance with the principles stated in the issued patents cited at the first part of this specification, both doors are effectively maintained closed. Nevertheless, the money slot 42 remains accessible to the user. 
     When business is done for the day, and it is time to cover the money slot 42 and prevent any access thereto, the business person opens the safe by operating lock means 30,31 to retract the lockbolt, then sliding door portion 21 to the right, then lifting on handle 28 to remove door portion 21, and then sliding second door portion 22 to the left and removing it. The operator then turns the second door portion 22 180-degrees about a vertical axis and repeats the locking procedure described above. This achieves the no-slot-access, and no-slot-visibility, condition shown in FIG. 4. 
     The foregoing detailed description is to be clearly understood as given by way of illustration and example only, the spirit and scope of this invention being limited solely by the appended claims.
