Description
BACKGROUND OF THE INVENTION
The field of this invention is postal drop-boxes.
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 mail 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
heretofore solved 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
drop-box 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.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the drawings, the postal drop-box of this invention 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 above the floor F. The
postal drop-box P of this invention provides for the housing of a
plurality of conventional flexible mail bags M (a portion of one
being shown in FIG. 4). As will be explained in detail, such mail
bags M are disposed in compartments or sections of the drop-box P
and are covered so that mail may be dropped into such bags, but
unauthorized removal of the mail or the bags is prevented. When the
officials of 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.
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 10 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, 11, 12, 14, 15 and 17 may be joined together by any
suitable connecting means such as welding, bolts or other known
attaching devices.
On the inner surfaces of each of the lateral support members 12, a
plurality of hooks 20 or other bag attaching means are provided for
securing a mail bag M in each compartment C so that it may be
readily attached to such hooks 20 and thereafter removed when the
bag M is filled with the mail.
The framework S is completely enclosed on the sides, front and
bottom by a housing H which is made of fiberglass, metal or any
other suitable rigid material and 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 S.
However, it will be understood that the housing H could have a back
portion which would also enclose the back 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 for the 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 that the 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 compartments C and the mail bags M which
are disposed therein.
The cover K is provided with 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 each of 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 35 to the lip 34a which is
relatively small and is not sufficient 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 to the
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 37b, 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 substantially 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 U.S. 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 11a (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 51a 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 compartments
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 10 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 would be 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 of the mail bags M which may be
readily picked up by the postal authorities.
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.
