BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The disclosed invention generally relates to a tray
assembly. More particularly, the disclosed invention relates to a
multi-purpose tray assembly for use in combination with variable
level surfacing such as inclined, stepped, or level support
surfaces.
[0003] 2. Description of the Prior Art
[0004] U.S. Pat. No. 5,249,397, which issued to Monaco ('397
Patent), and U.S. Pat. No. 5,913,782, which issued to Monaco et al.
('782 Patent), discloses a Knockdown Roof Platform for use on an
Inclined Roof. The '397 Patent and the '782 Patent describe certain
knockdown platforms for use on an inclined surface. The platforms

bracket is releasable enabling the table structure and the upright
leg structure to be pivoted on the hinge located interior to the
hollowed area on the underside of the table structure. The
collapsible locking bracket allows for the collapsing of the table
structure and the upright leg structure out of right angle relation
relative to one another and into a collapsed storage position where
the table structure and the upright leg structure extend generally
in a parallel relation.
SUMMARY OF THE INVENTION
[0005] The present invention provides a multiple purpose tray
assembly for inclined or level surfaces, which tray assembly may be
used in tandem with identical embodiments of the tray assembly for
forming larger, linked tray assemblages. In this last regard, it is
contemplated that the tray assembly(ies) may be coupled to one
another is side-by-side relation either by certain hardware based
fastening means or by tongue and groove type fastening means.
[0006] The tray assembly may comprise a plurality of legs, which
are stowable in a primary tray structure when not being used to
elevate the tray structure above a support surface. When used to
elevate the primary tray structure above variable level support
surfacing, such as stepped, inclined, or horizontal support
surfacing, the legs may each be adjusted relative to the primary
tray structure for properly maintaining a horizontal tray
configuration relative to the support surfacing.
[0007] To achieve these and other readily observable objectives,
the present invention specification describes a tray assembly for
use in combination with variable level support surfacing so as to
provide a horizontal tray. The tray assembly according to the
present invention comprises a first or primary tray structure and
at least one pair of tray support legs. The primary tray structure
has an upper tray surface, a lower tray surface, opposed
leg-receiving slots extending intermediate the upper to lower tray
surfaces, and opposed leg-receiving apertures extending from the
upper to lower tray surfaces. The tray support legs are removably
receivable in the tray-receiving slots for stowage, and are
removably receivable in the leg-receiving apertures for supporting
the primary tray structure in horizontal spaced relation relative
to a support surface.
[0008] The leg-receiving apertures and tray support legs comprise
certain means for selectively and orthogonally varying the position
of the respective tray support legs relative to the respective
leg-receiving apertures, which means enhance a user's ability to
use the tray in combination with variable level surfacing. Said
means may be preferably and cooperatively defined by aperture tabs
formed within the leg-receiving apertures and tab-receiving
channels formed within the tray support legs. The aperture tabs are
receivable in the tab-receiving grooves for adjusting the position
of the tray support legs relative to the leg-receiving
apertures.
[0009] The tab-receiving channels each comprise a vertical groove
portion and a series of horizontal groove portions continuous or
contiguous with the vertical groove portion. The vertical groove
portion enables the user to orthogonally adjust the position of the
respective tray support legs relative to the leg-receiving
apertures, and the horizontal groove portions enable the user to
orthogonally fix the position of the respective tray support legs
relative to the leg-receiving apertures.
[0010] Each leg-receiving aperture may preferably comprise opposed
aperture tabs, and each tray support leg may preferably comprise
opposed set of tab-receiving channels. It is contemplated that the
opposed aperture tabs and opposed sets of tab-receiving channels
may well function to enhance stability of the tray support legs as
removably received in the leg-receiving apertures. As earlier
stated, the tray assembly may further comprise certain means for
coupling a second tray structure to the first tray structure, which
second tray structure is substantially identical to the first or
primary tray structure.
[0011] Certain matter receiving pockets may be formed within the
primary tray structure(s) and thus the tray can be used in
painting, plumbing, electrical, or roofing applications. The tray
structure may be used by a worker so that he or she may place tools
or hardware in the pockets so as to organize one's building
materials and supplies. Other objects of the present invention, as
well as particular features, elements, and advantages thereof, will
be elucidated or become apparent from, the following description
and the accompanying drawing figures.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0030] Referring now to the drawings, the preferred embodiment of
the present invention concerns a tray assembly 10 for use in
combination with variable level support surfacing so as to provide
a horizontal tray structure for holding and/or compartmentalizing
various matter thereupon. It is contemplated that the variable
level support surfacing may be defined by a stepped surface such as
a stair case 11 as generally depicted in FIG. 11; or an inclined
surface such as a sloped roof 12 as generally depicted in FIG. 10;
or a horizontal surface as may be generally gleaned from FIGS.
6-9.
[0031] The tray assembly 10 comprises a tray structure 13 having an
upper tray surface or portion as generally depicted in FIGS. 1-3,
5, 10, and 11; and a lower tray surface or portion as generally
depicted in FIGS. 4 and 17. It should be noted that the primary
tray structure 13 is upendable such that the upper and lower tray
portions may be interchangeably used as matter-supporting
surfaces.
[0032] In other words, depending on the task at hand, the user may
wish to utilize the upper portion to support/organize matter as
seen in the noted figures with a first pocket arrangement or
alternatively the lower portion with a second pocket arrangement.
Pockets 40 are further preferably formed in the upper and lower
portions to provide the user with added means for organizing matter
upon the tray structure 13.
[0033] The upper and lower tray surface or portions further
comprise opposed leg-receiving slots or grooves 14, which extend
toward the opposed tray surfaces or portions and are sufficiently
deep to receive and stow tray supportive legs 15 as generally
depicted in FIG. 5, 10, and 11. FIGS. 1-3 depict legs removed from
the slots or grooves 14. When legs are removed from the slots or
grooves 14, other matter (e.g. hardware) may be received
therein.
[0034] The slots or grooves may be outfitted with tabs 21 sized and
shaped so as to selectively retain the legs 15 within the slots 14.
The upper tray surface or portion depicts the slots 14 relatively
closer to the outer periphery of the tray structure 13 and the
lower tray surface or portion depicts the slots relatively closer
to the center of the tray structure 13.
[0035] The upper and lower slots or grooves 14 are substantially
parallel to one another and extend between end-located, opposed
leg-receiving apertures 16. In this last regard, it may be noted
that the tray structure 13 may be rectangular in shape and the
slots 14 may preferably extend intermediate opposed pairs of
leg-receiving apertures 16 in the length direction of the tray
structure 13.
[0036] The opposed leg-receiving apertures 16 situated at or
adjacent the four corners of the tray structure 13 extend through
or from the upper to the lower tray surfaces. As introduced
heretofore, at least one pair of tray support legs 15 form part of
the tray assembly 10, which legs 15 are removably receivable in the
tray-receiving slots 14 for stowage, and are removably receivable
in the leg-receiving apertures 16 for supporting the tray structure
13 in a horizontal and spaced orientation relative to a support
surface.
[0037] Together, the leg-receiving apertures 16 and tray support
legs 15 preferably comprise certain means for selectively and
orthogonally varying the position of the respective tray support
legs 15 relative to the respective leg-receiving apertures 16,
which means essentially function to enhance a user's ability to use
the tray assembly in combination with variable level surfacing.
[0038] Said means for selectively and orthogonally varying the
position of the respective tray support legs 15 relative to the
respective leg-receiving apertures 16 may be preferably and
cooperatively defined by aperture tabs 17 formed within the
leg-receiving apertures 16 and tab-receiving channels 18 formed
within the tray support legs 15. The aperture tabs 17 are sized and
shaped to be receivable in the tab-receiving channels 18 so as to
allow the user to orthogonally adjust the position of the tray
support legs 15 relative to the leg-receiving apertures 16.
[0039] In this last regard, it should be noted that the
tab-receiving channels 18 comprise a vertical groove portion (as at
19) and a series of horizontal groove portions (as at 20), which
horizontal groove portions 20 are contiguous with the vertical
groove portion 19. The vertical groove portions 19 of each leg 15
thus enable the user to orthogonally adjust the position of the
respective tray support legs 15 relative to the leg-receiving
apertures 16 and the horizontal groove portions enable the user to
orthogonally fix the position of the respective tray support legs
15 relative to the leg-receiving apertures 16. In other words the
tab 17 may be received in the vertical groove portion 19 so that
the leg 15 may extend through the aperture 16 and be displaced
orthogonally relative thereto. The leg 15 may then be rotated such
that the tab 17 may be guided into a horizontal groove portion 20
so that the leg 15 may be orthogonally fixed relative to the
aperture 16.
[0040] To enhance the stability of the tray support legs 15 as
removably received in the leg-receiving apertures 16, it is
contemplated that the leg-receiving apertures 16 may each
preferably comprise opposed aperture tabs 17, and the tray support
legs 15 may each preferably comprise opposed sets of tab-receiving
channels 18. The opposed cooperative means for selectively and
orthogonally varying the position of the respective tray support
legs 15 relative to the respective leg-receiving apertures 16
provide bi-directional or opposed structure for further
orthogonally fixing the legs 13 at a given displacement relative to
the tray structure 13.
[0041] The tray assembly preferably further comprises certain means
for coupling a second tray structure 30 to the first tray structure
13, which second tray structure 30 is substantially identical to
the first tray structure 13. It is contemplated that the means for
coupling the second tray structure 30 to the first tray structure 3
may preferably be defined by tongue-and-groove type flanges 22 that
extend outwardly from the side(s) of the tray structures 13 and
30.
[0042] It may be seen from an inspection of the figures that
flanges 22 are of two types, namely outwardly and upwardly
extending flanges as at 23, and outwardly and downwardly extending
flanges as at 24. The flanges 21 are arranged on the first and
second tray structures 10 and 30 such that the flanges 24 mate with
or couple with flanges 23 as generally depicted in FIG. 16. It may
be seen from a consideration of the figures, and in particular
FIG.16 that the upwardly extending portions of flanges 23 are sized
and shaped to be received in the grooves adjacent the downwardly
extending portions of flanges 24.
[0043] While the above description contains much specificity, this
specificity should not be construed as limitations on the scope of
the invention, but rather as an exemplification of the invention.
For example, it is contemplated that the present invention
essentially describes and teaches a tray assembly for use in
combination with variable level support surfacing so as to provide
or maintain a horizontal tray. The tray assembly comprises a first
or primary tray structure and at least one pair of support legs.
The first tray structure has an upper tray portion, a lower tray
portion, and opposed leg-receiving apertures extending from the
upper to lower tray portions. The tray support legs are removably
and orthogonally receivable in the leg-receiving apertures for
supporting the first tray structure in horizontal spaced relation
relative to a support surface.
[0044] The leg-receiving apertures and tray support legs may
preferably comprise certain means for selectively and orthogonally
varying the position of the respective tray support legs relative
to the respective leg-receiving apertures, which means may well
further function to enhance a user's ability to use the tray in
combination with variable level surfacing. Said means may be
cooperatively defined by aperture tabs formed within the
leg-receiving apertures and tab-receiving grooves or channels
formed within the tray support legs. The aperture tabs are
receivable in the tab-receiving grooves for adjusting the position
of the tray support legs relative to the leg-receiving
apertures.
[0045] The tab-receiving grooves may comprise a vertical groove
portion and a series of horizontal groove portions continuous with
the vertical groove portion. The vertical groove portion enables
the user to orthogonally adjust the position of the respective tray
support legs relative to the leg-receiving apertures, and the
horizontal groove portions enable the user to orthogonally fix the
position of the respective tray support legs relative to the
leg-receiving apertures.
[0046] Each leg-receiving aperture may preferably comprise opposed
aperture tabs, and each tray support leg may preferably comprise
opposed set of tab-receiving grooves. The opposed aperture tabs and
opposed sets of tab-receiving grooves may well enhance stability of
the tray support legs as removably received in the leg-receiving
apertures. It is contemplated that the legs 15 could comprise male
structure (such as certain leg tabs), however, for receipt in
female structure (such as certain aperture channels) otherwise
formed in the apertures 16, though this latter feature has not been
specifically illustrated.
[0047] The tray assembly according to the present invention may
further preferably comprise certain means for coupling a second
tray structure to the first tray structure. As earlier stated,
these means may be preferably defined by certain flange type tongue
and groove structure, but could well be provided by certain other
structure such as fastening hardware and alignable fastening
hardware apertures on adjacent tray structures.
[0048] The first and second (or third) tray structures may each
preferably comprises certain leg-stowage means for selectively
stowing the tray support legs. In this regard, it is contemplated
that either the upper tray portion and/or the lower tray portion
may comprise leg-receiving slots or grooves (as at 14) outfitted
with means for removably retaining the legs received therein, which
grooves 14 are sized and shaped so as to be sufficiently deep to
completely receive the legs within the thickness of the tray
structure between the maximum upper and lower dimensions of the
upper and lower tray portions.
[0049] Stated another way, the tray assembly according to the
present invention may be said to provide a tray structure having
upper and lower tray portions, and leg-receiving apertures (as at
16) axially and orthogonally extending from the upper to lower tray
portions. A plurality of support legs, the support legs are
coaxially receivable in the leg-receiving apertures for supporting
the tray structure in horizontal spaced relation relative to a
support surface.
[0050] The leg-receiving apertures and support legs may well
comprise certain means for selectively and orthogonally varying the
position of the respective support legs relative to the respective
leg-receiving apertures, which means may be said to further enhance
a user's ability to orient the tray in horizontal spaced relation
relative to a support surface. The means may be cooperatively
defined by tabs and grooves or channels respectively formed in
either the legs or apertures. The tabs then are receivable in the
grooves for adjusting the position of the support legs relative to
the leg-receiving apertures.
[0051] Accordingly, although the invention has been described by
reference to a preferred embodiment, it is not intended that the
novel tray assembly be limited thereby, but that modifications
thereof are intended to be included as falling within the broad
scope and spirit of the foregoing disclosure and the appended
drawings.
