Abstract
An organizer for maintaining items such as mail in a convenient, readily accessible generally stacked condition. The organizer has a receptacle tray with a retainer which is angularly disposed within the tray and longitudinally slidable therein along a track. A foot on the retainer is held in frictional engagement with the track or bottom of the organizer by the contents held between the retainer and an end of the tray. The user may easily disengage the retainer and move it in either direction by manually applying a counter force to the upper edge of the retainer. In the preferred embodiment, the tray is a standard postal tray of light weight material. In an alternate embodiment, an optional return spring may be provided to urge the retainer into engagement with the retained contents of the tray.
Description
FIELD OF THE INVENTION
The present invention relates to an organizer and more particularly relates to an organizer receptacle for securing and maintaining items such as mail in an organized, accessible manner allowing the user to remove or insert items.
BACKGROUND OF THE INVENTION
Mail is generally automatically sorted by an operation termed “delivery point sequence”. Mail is generally placed in a postal tray which is transported along the delivery route in a postal delivery vehicle. As the postal delivery person reaches a delivery location, the mail addressed to that location is removed from the tray and delivered. As the mail is removed from the conventional postal tray, the remaining mail items can become disorganized as the removed mail will cause the remaining mail to no longer remain upright in an organized manner but will fall to a flat position on the bottom of the tray.
The conventional postal tray is generally rectangular having an open top with openings at either end which serve as handles. The material of the tray is generally a light weight corrugated material and several official tray designs are in use which are designated the “EMM” and “MM”. While these postal trays work well, are light weight and convenient to use in a delivery vehicle, the conventional trays have the disadvantage that the flat mail, letters, and the like are not maintained in a convenient upright position but rather may often assume a flat position making it necessary for the delivery personnel to manually search through the remaining mail for the items to be delivered to the next succeeding mail patron. This can occur if the trays are only partially filled during the initial sorting operation and also occurs as filled trays are emptied during the delivery operation.
A number of approaches to solving the problem dealing with conveniently maintaining mail in an easily accessible position can be found in the prior art. In some cases, individual postal delivery personnel may carry some type of cardboard or wood separator which are used to assist in maintaining the mail in a generally vertical position.
There are various approaches to organizing mail for delivery which can also be found within the patent literature. U.S. Pat. No. 4,643,306 teaches a postal tray provided with individual tray dividers for sorting and delivery of the mail.
Similarly, U.S. Pat. No. 3,491,909 teaches a method and apparatus of separating a tray or enclosure into individual compartments.
Benoit in U.S. Pat. No. 3,746,181 shows a series of individual separators each separator having a base portion. The base portion of the separator is loaded with articles to maintain it in place. This type of separator is designed for static storage of articles.
U.S. Pat. No. 4,889,397 shows a mail delivery system including a plurality of portable trays each having a bottom, an open top and at least two rigid and oppositely disposed sides affixed to the bottom, at least one open side and a gate member to open and close the open side. Separators are removably attached to at least the bottom. Regularly spaced slots within the bottom receive the separators. At least one set of handle members assist in the transportation of the portable tray and assist in the withdrawal or insertion of the portable tray from holder members arranged to receive the tray. A tray case containing a plurality of holder members to removably receive the plurality of portable trays, members for raising and lowering the case and the trays from the loading position to a sorting position are provided. A transport member containing a plurality of holder members to receive the portable trays and transport the portable trays from the tray cases to a tray rack are provided in a delivery vehicle.
A mail sorting rack is shown in U.S. Pat. No. 4,484,685 which has a rack structure with a plurality of parallel divider blades between which the postal worker inserts mail pieces for various addresses in order. A tray underlies the mail which enables the mail worker to pull the tray free of the extending blades eliminating the dividers from the sorted mail so the worker may more easily group and band them for delivery.
U.S. Pat. No. 5,207,347 shows a postal tray adjustable organizer having a translucent framework having an upright and flat bottom portion slidably affixed within the cavity of the postal tray. A finger-operated spring loaded shaft extends outwardly against the sides of the postal tray. The user may grasp the release handles of the spring loaded shaft and the organizer may be slid forward along the tray to secure the mail in an upright position.
Therefore, while the prior art suggests various approaches to the problem of maintaining mail in an organized, easily-identifiable arrangement, these prior art arrangements have not generally been embraced by the Post Office department for a number of reasons. Many of these devices are cumbersome, impair the visual identification of the mail. Further shortcomings of prior art devices is that they do not adapt themselves for use with the conventional light weight, flexible postal trays which are in use today such as the EMM and MM trays.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an organizer receptacle for documents and more particularly to an improved postal tray for use by postal personnel which tray will maintain the mail items in an organized, orderly and upright fashion and allowing easy removal of mail items during the delivery route.
The present invention provides a postal organizer having an article receptacle with a bottom, opposite sides and ends extending upwardly from the bottom and having an open top. Preferably the configuration of the receptacle and side walls permit the receptacles to be easily stacked when empty.
An elongated track extends within the bottom of the receptacle at least partway between the opposite ends at an intermediate location between the sides. A retainer, which is preferably generally a planar plastic panel, has a slide on its bottom side. The slide is engageable in the track so that the divider may be moved longitudinally within the receptacle to maintain items in an upright position between one side of the divider and one end of the tray. A foot extends from the lower end of the retainer. In the normal position, the retainer is inclined so that mail items abutting the side of the panel which forms an acute angle with respect to the bottom of the tray will impose a slight rotative force on the retainer causing the foot to engage either the track or the bottom of the receptacle, resulting in a frictional force which prevents unintended movement of the retainer. To move the retainer, the user may simply apply a slight opposite rotative force to the retainer to disengage the foot allowing it to be freely moved to accept additional letter items or to compact those items remaining after items have been removed. In an alternate embodiment, a spring may be provided extending between the slide and one end of the receptacle.
The organizer of the present invention may be utilized with a conventional postal tray such as those in use by the Post Office department or may be a specially fabricated item. A false floor may be provided overlying the bottom if the device is used in connection with a conventional postal tray. Also, a stop may be provided to limit the movement of the divider in one direction.
BRIEF DESCRIPTION OF THE DRAWINGS
The present invention will be more fully understood from the following description, taken in conjunction with the accompanying drawings in which:
FIG. 1
is a perspective view of the postal organizer of the present invention;
FIG. 2
is a top view of the organizer of the present invention;
FIG. 3
is a longitudinal cross sectional view of the organizer;
FIG. 4
is an enlarged detail view of the slide and track;
FIG. 5
is an exploded perspective view; and
FIG. 6
is a cross-sectional view showing a plurality of organizers in a stacked, nested condition.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, the organizer of the present invention is generally designated by the numeral
10
and has a generally rectangular bottom
12
, opposite sides
14
and
16
, opposite ends
18
and
20
which generally define a tray-like receptacle having an open top and defining a compartment
22
for receipt of items such as mail. Preferably, the side walls and end walls extend upwardly and diverge slightly outward from the bottom wall
12
so the plurality of organizers as shown in
FIG. 6
may be easily stored and stacked in a nested condition. In this way, separation of an organizer from a stack of nested organizers is facilitated.
The opposite end walls
18
and
20
are each provided with elongated apertures
26
which serve as handles allowing the user to easily grasp and pick up the organizer.
The organizer as described above generally conforms to the construction of the standard postal tray. The dimensions of the tray may be approximately 14″ wide by 25″ long by 6½″ high. In a preferred embodiment, the tray is fabricated from a suitable light weight material such as a coated corrugated fiber or plastic material.
As has been discussed above, the problem with conventional postal trays is that they are satisfactory when the tray is substantially full. However, as mail items are removed, the remaining items will tend to fall in a flattened condition on the bottom of the tray. The present invention provides an arrangement in which a retainer may be moved as mail items are removed in a direction to maintain the remaining mail in a generally upright position compacting the items between the retainer and an end wall of the organizer.
Accordingly, the bottom of the tray is provided with a track
40
which is preferably an extruded plastic member which extends from the inner side of wall
18
longitudinally at an intermediate location between the side walls
14
and
16
. The track may extend the entire length of the bottom
22
of the organizer tray to end wall
20
or may terminate spaced from the end wall
20
as seen in FIG.
2
.
As best seen in
FIG. 3
, the track includes a pair of upstanding spaced-apart webs
42
,
44
. A planar base
46
extends between the lower ends of webs
42
,
44
. The base
46
is secured to the interior of the bottom wall
22
by suitable means such as an adhesive. The track base may extend transversely beyond the webs
42
,
44
for strength and to reinforce the tray or receptacle structure. Longitudinal reinforcing ribs
45
may also be provided on the base. The upper ends of webs
42
,
44
each carry an inwardly extending flange
42
A,
44
A, respectively. The track slidably receives the retainer
50
.
The retainer is best seen in
FIGS. 2 and 4
and includes a panel
52
having opposite surfaces
54
,
56
with cut-outs
53
for reduced weight and to provide a convenient grip. The panel is shown as rectangular having opposite edge
58
and
60
and upper edge
62
and bottom edge
64
. The configuration of the retainer
50
generally conforms to the cross-sectional configuration of the mail receiving compartment of the tray and may be somewhat narrower.
A foot
66
extends from the lower end of the retainer at an intermediate location. A slide
70
projects from the underside of the foot
66
. The slide
70
defines slots
72
and
74
which, as best seen in
FIG. 4
, receives the inwardly extending flanges
42
A and
44
A so that the retainer is slidably restrained within the track. An adjustable stop
76
depends from the end of the foot
66
.
It will be seen that the retainer
50
is angularly disposed with respect to foot
66
. The surface
56
forms an acute angle with respect to the bottom of the tray while surface
54
forms an obtuse angle. Surface
56
is maintained against the items such as mail “M” within the tray. In this way, the mail items within the tray will apply a slight force in the direction of the arrow “A” against surface
56
. This force produces a slight moment which will cause the foot
66
to pivot slightly downwardly into engagement with the track. This slight moment will be sufficient so as to frictionally restrain the retainer from unwanted sliding motion. To release the retainer
50
to move it in either direction, the user will simply grasp the upper end of the retainer
50
applying a slight force in the opposite direction as shown by the arrow “R” which will pivot the foot
66
out of frictional engagement with the track allowing the retainer to be freely moved. In this way, the user can easily adjust the position of the retainer to accept more mail or maintain the existing or remaining mail items in an upright position as items are removed. The retainer is preferably molded from a suitable plastic material such as a light weight plastic such as acrylic, PVC or polyethylene.
As pointed out above, the present invention lends itself to incorporation in existing mail trays. To facilitate the adaptation of the present invention to conventional mail trays, it is preferred that a false bottom
80
be positioned within the tray overlying the bottom
12
. Referring to
FIG. 5
, the false bottom
80
has opposite sides
82
,
84
and opposite ends
86
,
88
which conform to the interior dimensions of the lower part of the mail receiving compartment
22
. An elongated slot
90
is provided within the false bottom which slot overlies the track
40
. Preferably the slot terminates at a location
92
short of the end of the false bottom. The termination of the slot at this location prevents the slide from being fully extended to the end wall
20
as the stop
76
will engage the end
92
of the slot.
Once the mail is sorted into the tray, the postal carrier will move the retainer to a location to maintain the mail in an upright position. As mail items are removed as the carrier proceeds along his or her route, the retainer can easily be manually moved toward end wall
18
as the volume of mail “M” within the tray decreases. This is accomplished by simply applying a slight rotative manual force in the direction indicated by the arrow “R” to the upper edge of the retainer freeing it so that it will easily slide. Once the retainer is moved to a new position, the carrier will release the force and the slight moment applied by the remaining mail will return the divider to a frictionally fixed position.
As shown in
FIG. 6
, the organizer of the present invention lends itself to being stacked. To nest or stack the trays, the retainer
15
is moved to a position immediately adjacent end
18
and the trays may then be conveniently stacked.
FIG. 3
also shows the addition of an optional biasing spring
100
extending in track
40
between the retainer and the end wall
18
which will serve to assist in maintaining the retainer in a snug position against the items between the retainer and the end wall. The spring will exert a force normally urging the retainer leftward as seen in FIG.

It will be seen from the foregoing, the present invention provides a light weight, versatile, highly effective postal tray. It will be obvious to those skilled in the art to make various changes, alterations and modifications to the invention described herein. To the extent such changes, alterations and modifications do not depart from the spirit and scope of the appended claims. They are intended to be encompassed therein.
