Description
BACKGROUND OF THE INVENTION
The present invention relates to a mailbox construction for
residential use that may be easily mounted on a vertical wall or
panel either at the residence or at a location removed
therefrom.
Mailboxes normally used for residential purposes have been
constructed with a slot at the top through which articles of mail
were inserted for deposit into the interior of the mailbox. Even if
the mailbox were locked by the owner thereof, it was possible
heretofore to remove the mail articles through the top slot by
inserting some form of a wire grasping device or the like, or by
simply reaching through the slot and grasping the articles and
withdrawing them from the mailbox.
Prior to the instant invention some attempts have been made to
devise a mailbox for preventing the unauthorized removal of mail
through the mail slot thereof. However, in many of these prior
known constructions the mail articles were not completely concealed
within the mailbox; and as a result, these mailboxes were not
effective in preventing the unauthorized removal of the mail
therefrom. Those mailboxes that were effective in providing an
anti-theft construction were fairly complicated in structure, and
as a result were prohibitive in cost.
SUMMARY OF THE INVENTION
The present invention relates to a mailbox construction that
includes a main housing on which a cover member is pivotally
mounted. The cover member includes a top wall in which a slot is
formed, and located beneath the top wall and adjacent to the slot
is a baffle member that cooperates with additional directing
elements that are mounted in the main housing to define a
restricted passage through which articles of mail pass upon being
inserted through the slot. The baffle member and directing elements
as located in the main housing and cover member also prevent
unauthorized withdrawal of the articles through the mail slot,
since they tend to obstruct removal of the articles through the
slot. The main housing and cover member are also constructed such
that the front wall thereof is inclined to the vertical, wherein
articles of mail deposited in the main housing are inclined or fall
forwardly against the front wall, thereby further preventing
possible theft or unauthorized withdrawal of the mail articles from
the mailbox.
Accordingly, it is an object of the present invention to provide a
mailbox construction that provides for easy insertion of articles
of mail therein but that prevents unauthorized removal of the mail
articles from the mailbox.
Another object is to provide a mailbox having antitheft protection
as defined by interior baffling and inclination of the front wall
of the mailbox, wherein articles of mail deposited in the mailbox
are located in such a way that prevents the easy withdrawal
therefrom, the baffling further insuring that the articles cannot
be extracted from the mailbox through the slot in the top wall
thereof.
Other objects, features and advantages of the invention shall
become apparent as the description thereof proceeds when considered
in connection with the accompanying illustrative drawings.

DESCRIPTION OF THE INVENTION
Referring now to the drawings and particularly to FIGS. 4 and 7,
the mailbox construction as embodied herein is generally indicated
at 10, and, as shown, is applicable for use as a residential
mailbox either attached to a vertical wall or panel at the
residence or at a point removed therefrom. It is also understood
that the mailbox construction of the present invention may be used
at locations other than residences, particularly in rural
areas.
The mailbox construction 10 comprises a main housing generally
indicated at 12, on which a cover member generally indicated at 14
is pivotally mounted. The main housing 12 is defined by a rear wall
16 to which are joined side walls 18. A foreshortened front wall 20
is joined to the side walls 18 and is rounded at the bottom thereof
to form a bottom wall 22 that is joined to the rear wall 16. The
side walls 18 have a generally triangular configuration in
elevation and project rearwardly of the rear wall 16 to define a
recess therebetween. As will be described, the triangular
configuration of the side walls 18 provides for locating of the
front wall 20 in an inclined position with respect to the vertical,
and this conformation of the front wall is particularly useful in
locating articles of mail within the main housing in such a way as
to prevent unauthorized removal therefrom.
Joined to the rear wall 16 on the interior surface thereof and
adjacent to the upper end is a downwardly projecting directing
element 24. A similar downwardly projecting directing element 26 is
also secured to the rear wall 16 of the main housing and is spaced
below the baffle element 24. As will be described, the directing
elements 24 and 26 cooperate to prevent unauthorized withdrawal of
articles of mail from the interior of the main housing 12.
As more clearly illustrated in FIGS. 2 and 3, the bottom wall 22
which is a continuation of the foreshortened front wall 20 is
joined to the rear wall 16 and is inclined downwardly from front to
rear. This configuration of the bottom wall 22 insures that
articles of mail that have been deposited within the main housing
12 will fall forwardly against the front wall 20, since the bottom
edges of the articles must slide toward the rear wall 16 due to the
curvature of the bottom wall 22.
The cover member 14 is defined by side walls 28 to which are joined
a front wall 30, the side walls depending below the front wall 30
and providing for engagement of a hasp 32 on a lock element 34, the
hasp being secured to the front wall 30 ahd having a slot for
accommodating the lock element 34 that is fixed to the front wall
20 of the housing 12. It is understood that any convenient lock can
be inserted through the lock element 34 for securing the cover
member 14 in the locked position on the main housing 12.
In order to connect the cover member 14 to the main housing 12 in
pivotal relation, the side walls 28 of the cover member overlap the
side walls 18 of the main housing and are pivotally connected
thereto adjacent to the rear thereof by bolts 36. Interior lock
nuts 37 are mounted on the bolts 36 and secure them in place. As
shown in FIG. 4, the cover member 14 is pivotally movable on the
side walls 18 of the main housing 12 to expose the interior of the
main housing for removal of mail articles therefrom or for deposit
of articles therein, as desired.
Joined to the front wall 30 of the cover member 14 and inclined
upwardly with respect thereto is a top wall 38, the uppermost end
of which engages the rear wall 16 of the main housing when the
cover member is in the closed position thereof. Formed in the
inclined top wall 38 of the cover member 14 is a laterally
extending slot 40 that defines an entry slot for articles of mail
that are inserted into the main housing 12. One of the features of
the present invention is to prevent the unauthorized removal of the
articles of mail from the mailbox construction. For this purpose, a
substantially triangularly shaped baffle member 42, as seen in
cross section, is secured to the underside of the top wall 38 and
is disposed in adjacent relation to the entry slot 40. The baffle
member 42 projects inwardly of the main housing 12 so that is is
located in spaced relation with respect to the downwardly
projecting directing element 24 that is mounted on the rear wall 16
of the main housing. The space between the baffle member 42 and the
element 24 defines a restricted passage that is also tortuous or
nonlinear with respect to the entry slot 40, so that when the
articles of mail are inserted through the entry slot, the direction
of descent thereof is changed as they pass through the restricted
passage. It is seen that this is particularly important in the
preventing of unauthorized removal of the articles by way of the
entry slot 40, since the articles must be lifted through the
restricted passage and then turned or twisted for removal through
the entry slot. The tortuous passage as defined by the baffle
member 42 and element 24 tends to prevent such removal, and the
articles of mail will strike the baffle member 42 or the element 24
if they are lifted upwardly in the direction of the entry slot 40.
It is also seen that the lower element 26 cooperates with the upper
element 24 to prevent the mail articles from aligning with the slot
42 and thereby acts to prevent unauthorized removal of the articles
of mail from the mailbox construction.
Since the entry slot 40 would normally be exposed to weather if the
mailbox construction were located outside of a residence or
dwelling, a cover plate 44 is provided for shielding the entry slot
and thereby prevents accumulation of water and other debris within
the main housing 12. The cover plate is pivotally secured to the
cover member 14, and for this purpose the side walls 28 of the
cover member have upwardly extending lugs 46 joined thereto that
are located in horizontal alignment with corresponding lugs 48 that
are secured to the upper surface of the cover plate 44. Pins 50
extend through the lugs 46 and 48 for pivotally locating the cover
plate 44 over the top wall 38 of the cover member. An upper wall 52
is secured over the recess as defined by the rear extension of the
side walls 18 and 28 of the main housing 12 and cover member 14,
respectively; and it is understood that the cover plate 44 is
pivotally moved with respect to the upper wall 52 that is fixed in
position.
If for any reason the mail articles as deposited through the entry
slot 40 become lodged in the restricted passage between the baffle
member 42 and the baffle 24, a preventer element 54 that is joined
to the underside of the pivoted cover plate 44 is provided and
extends through the entry slot 40 and interiorly of the main
housing 12 and cover member 14 when the cover member 14 is located
in the closed position thereof. Thus, the preventer element 54
would normally contact the lodged articles and would tend to urge
them downwardly through the restricted passage and into the
interior of the main housing.
The mailbox construction 10 is normally mounted on a vertical wall
or panel, and for this purpose, side brackets 56 are provided. As
illustrated in FIG. 7, the brackets 56 have an L configuration, the
outwardly extending portion thereof having an opening 58 formed
therein through which a screw or the like is inserted for fastening
the box construction on a vertical surface. In addition to the
brackets 56, or, in the alternative, interior fastening screws 60
may be inserted through the rear wall 16 of the main housing 12 and
into the surface on which the mailbox is mounted. It is understood
that the length of the fastening screws 60 must be sufficient to
bridge the space between the rear wall 16 and the rear edges of the
side walls 18 of the cover member when the cover member is located
in the closed position thereof.
In use of the device, the mailbox construction is normally located
on a vertical surface; and because of the inclination of the front
wall 20 and the bottom wall 22, articles of mail indicated at 62 in
FIG. 4 normally fall against the front wall 20 after they have been
deposited through the entry slot 40. In this connection the curved
bottom wall 22 causes the lower edges of the mail articles 62 to
move against the lower edge of the rear wall 16, thereby locating
the articles 62 in the inclined position against the front wall 20
as illustrated in FIG. 4. As the articles of mail 62 are deposited
through the entry slot, and this is accomplished upon lifting of
the cover plate 44, they pass through the restricted passage
between the baffle member 42 and directing element 24. After the
articles are deposited, the cover plate 44 is returned to the
closed position thereof, the preventer element 54 entering the
entry slot 44 and engaging any of the articles that have become
lodged in the restricted passage, thereby forcing the lodged
articles toward the bottom of the main housing 12. If for any
reason, an attempt is made to withdraw any of the articles of mail
from the mailbox, and assuming that the cover member 14 has been
locked to the main housing 12, the unauthorized removal of the
articles through the entry slot 40 would be prevented since the
baffle member 42 and the elements 24 and 26 restrict the exit
passage. Thus it is seen that any articles that are lifted upwardly
from the main housing 12 for withdrawal through the entry slot 40
would contact either the elements 24 and 26 or the baffle member
42. Further, the articles would have to be twisted through the
tortuous passage between the baffle member 42 and element 24 to
gain access to the entry slot 40, and such movement of the articles
in this manner would be unlikely.
While there is shown and described herein certain specific
structure embodying the invention, it will be manifest to those
skilled in the art that various modifications and rearrangement of
the parts may be made without departing from the spirit and scope
of the underlying inventive concept and that the same is not
limited to the particular forms herein shown and described except
insofar as indicated by the scope of the appended claims.
