Description
BACKGROUND OF THE INVENTION
This invention relates to a dish rack and tray and more
particularly, to a combination dish rack and tray that can be
folded to a compact form for storage and readily unfolded for
use.
It is known to utilize a folding dish drying rack to support dishes
and the like for drying. One prior rack was comprised of a
plurality of wire elements forming segments that were pivotally
connected to one another to provide a collapsible rack. An example
of this type of rack is shown in Einhorn U.S. Pat. No. 2,516,088.
Such rack was ordinarily placed on a sink top or alternatively, on
a separate tray member for directing the water draining from the
dishes, cups, bowls or the like into the sink.
In another arrangement, shown for example in Peters U.S. Pat. Nos.
990,454, a collapsible dish drainer rack was associated with a pan
or receiving the drained water.
Later, a collapsible dish draining rack was associated with a
substantially planar tray made for example from sheet metal. The
type of construction is illustrated in Jenness U.S. Pat. No.
2,479,118.
Rigid dish racks molded from plastic have been used in the home.
The racks are not collapsible and therefore, storage of such racks
can be difficult. None of the prior art known to me comprises a
combination dish rack and tray readily molded integrally from
plastic that can be readily folded into a compact form for storage
and then readily unfolded for use.
An object of the present is to provide an improved combination dish
rack and tray wherein the disadvantages and deficiencies of prior
constructions are obviated.
Another object of the present invention is to provide an improved
storable dish rack and tray made unitarily from plastic and
including four integrally hinged panels, the panels being provided
with support means for holding dishes and the like in position for
draining of liquid therefrom and the panels being constructed and
arranged for ease of folding to facilitate storage in a small
space.
Yet another object of the present invention is to provide an
improved combination dish rack and tray molded from plastic and
comprising four panels integrally hinged to one another, wall means
formed on the rear of each of the panels and at the sides of the
outermost panels, the panels and wall means being constructed and
arranged to permit ready folding for storage in a small space and
ready unfolding for use. Other objects and advantages of the
present invention will be made more apparent hereafter.

DETAILED DESCRIPTION OF THE PRESENT INVENTION
Referring now to FIG. 1 there is illustrated a combination dish
rack and tray 10 embodying the present invention and illustrated in
a folded condition ready for storage. Preferably, the device 10
comprises panel members integrally molded from plastic and hinged
one to the other.
turning to FIG. 2 there is illustrated the combination dish rack
and tray 10 unfolded for use. As shown the device 10 comprises
panel sections 12, 13, 14 and 15 hingedly connected to one another
along the adjoining or adjacent sides by hinge means 16, 17 and 18
formed integrally therewith. Side wall means 20 and 22 are
integrally formed with the outermost panels 12 and 15 respectively.
The side walls 20 and 22 may be decoratively formed as for example,
by scallops along the upper edge thereof, and are preferably
inclined downwardly and inwardly adjacent the front edge thereof so
as to help guide any water draining from the tray inwardly toward
the sink or suitable receptacle.
Integrally formed with the side wall 20 is a rear wall 24.
Integrally formed with the side wall 22 is a rear wall 26. The side
walls 20 and 22 respectively, merge smoothly with the rear walls 24
and 26, respectively. Separate rear wall means 28 and 30 are formed
on the panel 13 and 14 respectively. The rear wall segments 24, 26,
28 and 30 are separate one from the other and are offset one from
the other so as to permit interfitting relationship of the rear
wall segments when the dish rack and tray is folded, as shown in
FIG. 1. As illustrated, the panel 30 is forward of the panel 28.
Panel 28 is forward of the panel 26. The panel 26 is forward of the
panel 24. The offsetting construction of rear wall parts aids in
the folding of the combination dish rack and tray into a compact
organization.
As best shown in FIGS. 2, 6 and 8, support means for cups or the
like are positioned adjacent the side walls 20 and 22. The support
means comprise rows of finger-like elements 30, 32, 34 and 36 and
38, 40, 42 and 44 which extend upwardly from the tray 12. The
vertical extent of the support means 30, 32, 34, 36 is less than
that of the side wall 20. Similarly, the support means 38, 40, 42
and 44 is less in vertical height than the side wall 22. Vertically
extending triangular rib means 45, are provided generally
transverse to the plane of each finger-like element to help
rigidify them with respect to a respective side wall. In use, a cup
with the open end down will be positioned over a respective support
means. The cup will be spaced from the bottom of the tray and thus
freely drain water.
Also extending upwardly from the tray are support means for
retaining dishes or the like in a generally upright position to
facilitate better drainage of liquid. Such support means comprise a
pair of like upright members 46 and 48 each provided with a
plurality of transversely aligned like recesses 49 and 50. It will
be understood that a dish may be inserted in a generally vertical
plane and retained in a pair of transversely aligned recesses, 49,
50 in the uprights 46, 48. Preferably, the uprights 46 and 48 are
molded integrally with the panels 14 and 15 respectively, and are
supported in the desired generally vertical use position by means
of supporting ribs 52, which may be triangular in elevation view.
The upright members 46 and 48 are constructed so that they will not
interfere with folding from the use position to the storage
position. Specifically, the height of the members 46 and 48 is less
than that of the rear wall means 30. The member 46 is positioned on
panel 14 and the member 48 is positioned on panel 15 such that the
panels can be disposed at right angles without member 48 contacting
member 46.
Each of the panels 12, 13, 14 and 15 is provided with one or more
sinuous ridges or raised projections 60 for rigidifying each panel
and for assisting in drainage of fluid or liquid from a bowl or the
like lying on the panels which cooperate to define a tray. As
illustrated, each panel is provided with two sinuous members 60
extending substantially the entire length from front to rear of
each panel. For example, in use, if the panels had planar tops, and
a bowl were placed inverted onto the top of one or more panels, air
would not reach the interior thereof and there would be improper
drying. With the raised projections or bulges 60, the top surface
of each panel is not flat and air can reach the interior of the
bowl or the like and thus enhance the drying thereof. In addition,
the projections 60 help to rigidify and provide additional strength
for each of the panels 12, 13, 14 and 15.
The combination dish rack and tray 10 may be retained in the stored
position by means of ancillary fastening means, as for example, a
rubber band, strip, or the like positioned over the exterior.
Alternatively, interlocking means may be provided on the device 10
for holding the parts in the stored position. A projection 62 can
be formed on the side wall 22 and be adapted to engage within a
keyhole-like slot 64 or recess in the side wall 20. Other forms of
retention will be evident to those having skill in the art.
Extending upwardly from the base or top of the combination dish
rack and tray is a silverware holder identified generally by the
numeral 68. The silverware holder 68 (FIGS. 2, 4, 5, 11, 12 and 13)
is comprised of four panels 70, 72, 74 and 76 joined together by
integral hinge means 71, 73 and 75. Extending outwardly from each
of the panels 70, 72, 74 and 76 is a wall segment 80, 81, 82 and 83
respectively, which are of such a length as to be joined centrally
so as to subdivide an assembled silverware holder 68 into four
sections. The silverware holder 68 is retained in assembled
position shown in FIG. 2 by means of cooperating interlocking means
on the panels 70 and 76. The cooperating interlocking means or
latch means comprise projections or extensions 86 on the panel 76
which are adapted to be received within the cooperating retainers
87 on the panel 70. The projections 86, which are each rib-like in
form, extend substantially the entire length of the side of the
panel 76 and the cooperating latch means 87 are formed along the
length of the panel 70. The latch means may be substantially
coextensive with the ribs or alternatively the latch means 87 may
comprise cooperating lengths of spaced apart portions as best seen
in FIG. 11. In any event, there is a firm interengaging of parts 86
and 87 to hold the silverware holder assembled.
The dimensions of the panels 70, 72, 74 and 76 are such that the
silverware holder 68 can be retained in position on device 10 when
it is folded for storage. The holder 68 may be square as viewed in
plan when assembled, or it can be rectangular. In either event the
walls or panels will be proportioned so as to be less than the
width of an associated e.g. panel 14, and less in height than
adjacent panels 13 and 15. The holder 68 is preferably molded from
plastic, e.g. polypropylene. If desired, the hinge can be made from
polypropylene and molded into polyethylene panels. The device 10
can be similarly fabricated from molded polypropylene or a
combination of polyethylene and polypropylene.
Complementary locating and retaining means are provided between the
silverware holder 68 and the tray of the combination dish rack and
tray 10. The locating and retaining means comprises upwardly
extending projections 90 and 91 on the top of the panel 14 which
cooperate with slots 92 and 93 formed in the walls 70 and 74 of the
silverware holder 68. The slots 92 and 93 are in the panels 70 and
74 as best illustrated in FIG. 5.
Turning now to FIG. 7, 8, 9 and 10 there is shown further details
of construction of the combination dish reck and tray 10. Extending
from the bottom of the tray of the combination dish rack and tray
10 are a plurality of support means which are constructed and
arranged so as to angle or tilt the base of the tray toward the
front end. In the event the device 10 is supported on a horizontal
flat surface, the device 10 will be tiled toward the open end or
front end to assure drainage of liquid therefrom. As illustrated,
the support means comprise a plurality of half-moon projections
100, 101, 102, 103, and 104 which extend in alignment beneath each
of the panels. As best seen in FIG. 7, there are two rows of
projections beneath each of the panels 12, 13, 14 and 15 which form
the tray or base of the combination dish rack and tray. The fronts
of the panels are tapered or feathered to the forward end so as to
form an outwardly inclined lip to facilitate draining of liquids
from the tray.
With reference to FIG. 11 there is illustrated further detail of
the silverware holder 68. The divider wall 80, which is typical of
the walls 80, 81, 82 and 83, has a flat top and the lower portion
thereof is curved or contoured as illustrated in FIG. 11. Other
shapes are possible, as will be apparent to those skilled in the
art.
In FIG. 16 there is illustrated a typical hinge between a pair of
adjacent panels. Preferably the lower surface or outer surface of
the hinge is formed flat whereas the upper surface is intended
approximately two-thirds of the way. The indentation or recess 110
provides a means for folding of the hinge upon itself so as to
permit a full 90.degree. fold. Folding of the panels upon the
hinges is easy and there is provided a compact package for storage
when the panels are folded up as seen in FIG. 1. It is noted that
the construction of the hinges between the panels of the silverware
holder is of the same basic design.
Turning to FIGS. 14 and 15 there is illustrated a modification of
the support means for cups or the like. In this case the support
members, for example the support member 132, extends upwardly from
the base and the support rib 145 is indented from the wall 122. In
operation the projection 132 performs the same purpose as the
projection 32 and the only difference is in the molding of the
device 10.
There has been disclosed a presently preferred embodiment of the
present invention which comprises a unitarily formed construction
of four panels integrally hinged one upon the other and constructed
and arranged such that silverware holder may be folded readily
within the device. The device is relatively inexpensive to
fabricate and desirably provides a combination of a dish rack and a
tray in a single unit. If desired, the silverware holder may be
fabricated integrally with the base or alternatively it may be
fabricated as a separate unit. It will be understood that the
maximum dimension or height of the silverware holder is less than
that of the side walls to permit effective folding and storage of
the device.
While there has been shown and described a presently preferred
embodiment of the present invention it will be understood that
various changes and modifications may be made without departing
from the invention. Therefore, it is intended in the appended
claims to cover all such changes and modifications as fall within
the true spirit and scope of the claims.
