In the past, it has been customary to locate a rack for holding a plurality of mail bags in many office building lobbies and other public places. Such arrangement had the advantage over conventional mailboxes in that the mail bags were filled directly by the user rather than requiring the transfer of the mail by the postman from the conventional mailbox to the mail bag for transportation.
However, the open ma'il bags exposed the mail to the danger of unauthorized removal or tampering which has been of concern to many people for a number of years, but so far as is known, no one has heretoforesolved such problem.
SUMMARY OF THE INVENTION The present invention relates to a postal drop-box which has the advantages of removable mail bags or containers, but also overcomes the problem of unauthorized removal or tampering with the mail. The dropbox of this invention supports a plurality of mail bags or containers in a locked housing which has slots for dropping the mail into the mail bags or containers, such slots being positioned and constructed to prevent unauthorized removal of the mail from the mail bags or containers.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is an isometric view of the postal drop-box of this invention mounted on a wall of a building;
FIG. 2 is a side view of the postal drop-box of this invention shown in the mounted position on the wall of the building; y I
FIG. 3 is an isometricview of the framework and mounting means of the postal drop-box of this-invention. with the housing and cover removed;
FIG. 4 is a partial sectional view of the upper portion of the postal drop-box of this invention, particularly showing the cover mounted with the housing and the mounting means on the wall of a building; and
FIG. 5 is a partial sectional view illustrating one type of lock means which may be used for locking the cover of the postal drop-box of this invention to the housing thereof.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Considering the invention more in detail, the postal drop-box P of this invention includes a framework S (FIG. 3) which is preferably constructed of structural steel members of a square tubular construction or of any other suitable material. As illustrated in FIG. 3, the preferred framework S is formed with a back or inner longitudinal frame member 10, and a substantially parallel front frame member 11, which are joined together by laterally extending connecting members 12 which are spaced apart so as to define a plurality of compartments C, each of which is adapted to. receive one of the mail bags M. The back portion of the framework S also has vertically extending support members 14 which are welded or are otherwise connected to the longitudinal rear frame member and also to a lower rear frame member 15. Braces 17 extend upwardly from each of the vertical frame members 14 to the horizontal frame members 12 to provide support for the frame members 12 and the'front frame member 11. It will be appreciated that. the framed members 10, ll, l2, l4, l5 and 17 may be joined together by any suitable connecting .means such as welding, bolts or other known attaching devices.
I which is attached to the framework S by rivets, adhesive or any other permanent securing means. The rear of the framework S does not have to be covered or enclosed by the housing H because the postal'drop-box P is preferably mounted against the wall such as the wall W which provides the closure for the back portion of the framework 5. However, it will be understood that the housing H could have a back portion which would also enclose theback portion of the framework S if desired under some circumstances of'installation or use.
The housing H is open at the top so that the compartments C are accessible forthe insertion and removal of the mail bags M. A pivoted cover K is pivotally mounted at a longitudinal hinge 30 to the longitudinal frame member 10 (FIG. 4) so thatthe cover K may pivot from the closed position (FIGS. 1 and 2) to an open position (FIG. 4) and also to an even further opened position so as to provide full access to the com- In the drawings, the postal drop-box of this invention I is designated generally with the letter P. Such drop-box P is preferably mounted on a wall W of a building and normally is disposed so that its lower part is spaced -the postal department or other authorized personnel unlock the postal drop-box P, the mail bags M are accessible for ready removal with the mail already in the mail bags M in the normal manner.
vpartments C and the mail bags M which are disposed therein.
The cover K is providedwith overhanging sides 31 and an overhanging from portion 32 which are adapted to extend downwardly over the upper part of the housing H so as to make entry into the housing H difficult when the cover K is in the closed position. The cover K is also preferably formed in a specific manner to provide a mail slot 33 for eachof the compartments C. Such slots 33 are preferably identical to each other and therefore only one of same is described hereinafter. Thus, each slot 33 is preferably formed by providing a raised portion 34 on the cover K with a downwardly terminating lip 34a which terminates above the surface 35 opposite such lip 34a at each of the slots 33. Thus, there is a vertical space or clearance from the surface ficient in itself for a person to pass his hand and arm therethrough. To further restrict the opening of the slot 33 to a size which will prevent unauthorized retrieval of mail from the bags M when the cover K is in the closed position, each of the slots 33 has a restricting plate 37 therewith which is pivotally connected by a conventional spring loaded hinge 38 tothe cover K so that it is urged upwardly to cause the inner end 37a to contact the lip 34a to close the slot 33. The hinge 38 for each slot 33 is secured to the cover K in the vicinity of the surface 35 by a rivet or rivets 37!), or any other suitable attaching means. The restricting plate 37 may be made of relatively rigid metal or other materials which will not bend to any extent so that when the plate 37 is pivoted downwardly to its open position (dotted lines'in FIG. 4), its inner end 37a is disposed substan-' tially directly below the lip 34a to define the maximum vertical extent of the opening for the slot 33, which normally is about five inches. The size of such slot 33 can be adjusted for different types of mail by changing the mounting of the restricting plate 37. In some cases the plate 37 may be mounted without the hinge 38 so as to provide a fixed vertical space from the end 37a to the lip 34a. In any event, a person cannot stick his hand directly down into any mail bag M because of the restricted opening at the slot 33.
Any suitable lock means L, and preferably one approved and authorized by the US. Postal System, is utilized for securing the cover K to the housing H. As shown in the drawings, the lock L is mounted with the front frame 11 in a slot or recess lla (FIGS. 3-5) by welding or any other suitable attachment. The lock L has a locking pin 50 therewith which is adapted to extend into a lock opening S-la in a lock plate 51 secured to the cover K. The lock L has a key receiving portion 52 which projects through the front of the housing H for access by authorized personnel to unlock such lock means L when it is desired to gain access to the com-' partments C.
For mounting the postal drop-box P on the wall W, a mounting bracket or support 60 is provided which has a lower flange 61 therewith which is bolted or otherwise fastened to the wall W. The flange 61 extends substantially vertically and is joined with a substantially horizontal flange 62 which is then joined with another substantially vertical series of flanges 63 which are separated by slots 63a. The flange 63 is thus offset away from the wall W a distance great enough to receive the longitudinal frame member 10. The slots 63 are wide enough to receive the vertical frame members 14. so that the entire drop-box P is supported and retained against the wall W by positioning the frame member on the horizontal flange 62 and inwardly of the flange plates 63. Lateral shifting of the framework S is also prevented because of the interlocking of the vertical frame members 14 in the slots or spaces 63a between the flange members 63. In the mounting of the longitudinal frame member 10 in the support member 60, rivets or other attaching means may be used to extend through the flange sections 63 into the longitudinal frame member 10, but in most instances, the weight of the entire drop-box P will be sufficient so that no one can remove or gain access to the interior thereof without creating such a disturbance that the entry or removal of the box P wouldbe detected.
The use of the postal drop-box P is believed evident from the foregoing description. Primarily, it will be used in office buildings and other locations where it is desired to have a convenient postal drop-box available in an attractive manner while providing the advantages of the use ofthe mail bags M which may be readily picked up by the postal authorities. 7
The foregoing disclosure and description of the invention are illustrative and explanatory thereof, and various changes in the size, shape, and materials as well as in the details of the illustrated construction may be made without departing from the spirit of the invention.
