TRAY FOR GAME TABLE
Abstract
A lightweight, arcuate plastic tray for a circular table, a
series of which may be secured to the edge of the table to outstand
therefrom. Each tray includes a suitable arrangement of depressed
sections or wells to hold poker chips, glasses and food dishes. The
tray has radial ribs which engage the outside of a depending edge
structure of the table and an inside lip adapted to rest on the
edge structure. The tray is reinforced at its underside by a
framework adapted to rigidify the same and permit it to be securely
connected to the table, as by a latch engaging the inside of the
edge structure. This framework includes a radial bar, attached to
the underside of the center of the tray and adjacent the inner end
of which the latch is mounted, and a chord bar attached centrally
to the radial bar and at each end to the underside of the tray. The
three points of attachment of the framework, in a triangular
arrangement, rigidify the tray so that it may be formed of thinner
plastic and thus appreciably reduce its weight.

Description
This invention relates to trays and containers which are mounted on
a table, and more particularly to removable table trays for round
gaming tables and the like. As such, the invention will be
hereinafter referred to as a "table tray" or as a "tray for a round
table."
A normally built gaming table includes an integral ledge extending
around the circumference of the table for holding game apparatus,
such as poker chips, cards and the like, and also for holding
refreshment items, such as glasses, food snacks and the like.
However, most gaming tables with permanently attached trays are
expensive, difficult to handle and store, and such tables are not
commonly purchased by the general public. In contrast, small
circular folding tables of a standard size are very common because
they are low cost units and are easy to handle and store. They are
capable of being used for many purposes, including gaming. However,
as a gaming table, a circular folding table is not completely
satisfactory because of the lack of a suitable circumferential
ledge for holding chips and the like.
The present invention was conceived and developed with the above
considerations in view, and comprises, in essence, a curved tray
adapted to be fitted against and secured to the curved edge of a
round table to form an outward extension thereof. It is
contemplated that a plurality of trays, such as comprising
90.degree. segments, may be combined to provide a continuous set
extending completely around the table. As used herein, a round
table is usually circular, but may be oval or the like.
It follows that an object of the invention is to provide a novel
and improved tray for a round table which is adapted to convert the
table into a gaming table and to otherwise increase the possible
uses of the table, at the same time retaining the easily storable
feature.
Another object of the invention is to provide a novel and improved
tray for a round which is a lightweight, strong and rigid unit
adapted to snugly fit against and to outstand from the edge of the
table and is capable of supporting a moderate load, as when an
individual at the table may rest his elbows upon the tray.
Another object of the invention is to provide a novel and improved
tray for a round table, to fit against and outstand from the edge
of the table, which may be quickly and easily connected to and
disconnected from the table.
Another object of the invention is to provide a novel and improved
tray for a table having a circumferential, depending edge
structure, such as a tube, which is disposed just beneath the outer
edge of the top conforming to the shape of the top.
Another object of the invention is to provide a novel and improved
removable tray for a round table which is especially adapted to be
used with standard sizes of lightweight tables.
Other objects of the invention are to provide a novel and improved
tray for a table which is a low cost, neat appearing, simple,
rugged and durable unit.
With the foregoing and other objects in view, as will hereinafter
appear, the invention comprises certain constructions, combinations
and arrangements of parts and elements, as hereinafter described
and illustrated in the accompanying drawings, in which:
FIG. 1 is a small scale, isometric view of a round table having a
pair of trays of this invention mounted on the edge of the table in

another modification.
Referring more particularly to FIGS. 1 and 2 of the drawings, one
or more of the improved trays T are adapted to be mounted at the
edge of a table C having a circular top, and it is apparent that
the tray should be properly proportioned with respect to the
diameter of the tabletop for a proper fit. Accordingly, the trays
should be manufactured for standard sizes of tables. For example,
the table of FIG. 1 is a popular, low cost type which is commonly
used for playing games. The table is standard in size, and includes
a series of legs 19 supporting a circular top, which may include a
top plate 20, of rigid sheet material, such as hardboard or
plywood, and finished by a covering 21 of plastic or cloth, as in
FIG. 4. Top plate 20 is mounted upon a tubular rail 22 formed into
a circle to extend about the edge of the tabletop, with its outer
edge being approximately beneath the edge of the top plate 20.
Cover 21 extends around the edge and is lapped under top plate 20,
thus being clamped between the plate and rail 22. The top and rail
thus form the peripheral edge E of the table against which the
trays T abut and, as in FIGS. 2 and 6, the contact of the tubular
rail 22, circular in cross section, against the undersurface of the
flat top, forms a groove 23 at the edge E, which receives the
inward side of the tray rim, as hereinafter described. The table is
otherwise constructed in a conventional manner, the top being
attached to the rail in any suitable manner, as by conventional
clips (not shown) and the legs 19 being secured to conventional
brackets (not shown) mounted on the rail, at the inside.
Ordinarily, the legs are adapted to be folded underneath the
tabletop, when the table is not in use, but they may be fixed in
some models of tables.
Each tray T is generally arcuate in shape and adapted to fit
against the edge E of the table, with each tray being formed as a
quadrant, so that four trays may extend completely around a
circular table, as indicated by the broken lines 24 of FIG. 1. Each
tray is conveniently formed as a thin-walled, unitary structure of
a selected synthetic resin plastic, such as high impact
polystyrene, polycarbonate or an acrylic nitrile butadiene styrene
copolymer, being reinforced by a mounting bracket B of metal, as
will be described. The manufacture of tray T is preferably by
injection molding operations to better form various wells, ribs,
flanges and rims on the tray, as hereinafter described.
In plan, the tray T is elongated and curved as an arcuate segment,
being comparatively shallow and having flat-floored wells 25 and 26
at each side, surrounded by inclined walls including an arcuate
inner wall 27, an arcuate outer wall 28 and radial end walls 29. As
heretofore, stated, the tray T is proportioned to fit against the
edge E of the table C, part of this fit being at the extended
arcuate edge of a rim 30 at the top of the inner wall 27, the rim
lying parallel to the well floors and the edge of the rim fitting
into the groove 23 when the tray is in place, as in FIG. 6. Another
part of the fit is provided by an arcuate surface 32 of a pair of
central, radial ribs 33, as in FIG. 6, proportioned to engage rail
22, a similar arcuate surface 32 of an end flange 34, as in FIG. 4,
and a similar arcuate surface 32 of a pair of spaced intermediate,
radial ribs 35, as in FIG. 5.
The end walls 29 are each capped by narrow, outwardly extended edge
rims 36, from the outer edge of which an end flange 34 depends in a
generally radial direction to thus extend towards the center of
curvature of the arcuate segment. The arcuate, outer wall 28 is
capped by a narrow, outwardly extended rim 37, from which an
arcuate flange 38 depends. It will be noted that the rims 30, 36
and 37 merge together at the four corners of the tray and that the
outward ends of the flanges 34 merge with the adjacent ends of
flange 37 to form the outward corners of the tray. In addition,
intermediate ribs 35 are integral, as in FIG. 5, with the inner
wall 27, floor of well 26, outer wall 28, inner rim 30, outer rim
37 and outer flange 38. Center ribs 33 are similarly integral with
contiguous parts.
The wells 25 are separated by the closely spaced, transverse but
unitarily inclined walls 40 at the center of the tray, which are
positioned above center ribs 33, as in FIG. 7. Walls 40 merge with
the inner and outer arcuate walls and are interconnected at their
top edges by a center rim 41 which also merges into the inner and
outer wall rims 30 and 37, as in FIGS. 2, 6 and 7. Wells 25 and 26,
at each side, may also be divided, as by an auxiliary wall which is
not as high as the edge walls and formed by a pair of closely
spaced, radially transverse walls 43 which upstand from the floor
of the adjacent wells and their top edges interconnected by a rim
44, as in FIGS. 5 and 10. The ends of walls 43, as well as rim 44,
merge into the inner and outer walls 27 and 28.
The center ribs 33 form depending flanges on the underside of the
tray for attachment of a radial arm 45 of bracket B. For a similar
purpose, an obliquely oriented pair of retaining flanges 46 depend
from the underside of the tray, at each side. Each of the two pairs
of bracket flanges 46 are in spaced parallelism and each pair
commences at an outer corner of the tray and is aligned diagonally
thereon with respect to the outer and end walls of the tray, but in
a common alignment with the opposing pair of bracket flanges 46 at
the opposite end of the tray. Thus, bracket flanges hold a bar 47
of bracket B in a chordal arrangement with respect to the arcuate
tray, as in FIGS. 3, 8 and 9.
The bracket B is formed as a generally T-shaped member, as by arm
45 and bar 47, each being a rigid metal tube which is preferably
square in section, as illustrated, and secured to the underside of
the tray to rigidify the tray. Arm 45 may be the same size as bar
47, with the inner end 48 of the arm being reduced in section and,
as in FIG. 6, abutted against and attached to the center of bar 47
by welding, the reduced section of end 48 providing greater weld
area along the top and bottom of the end. Rivets 49, extending
through registering holes in the ribs or flanges and in the tubes,
secure the arm and bar to the respective tray ribs 33 and flanges
46, as in FIGS. 3 and 6-9. The steel chordal bar 47 is particularly
valuable because it supports the remote ends of the tray and, with
the steel arm 45, provides three areas of support in a triangular
relationship, thereby resisting bending or twisting of the tray and
also resisting an "elbow load" at any position on the tray. In
essence, the bracket B, when attached to the tray, provides an
essentially unitized structure.
The bracket B, thus connected to the retaining flanges underneath
the tray, will also lie underneath the tubular rail 22 of the table
whenever the tray is positioned against the edge of the table, as
in FIG. 6. It is to be noted that when so positioned with respect
to the circular rail 22, the bar 47 will extend across and beneath
rail 22 in a chordal arrangement, while the arm 45 will be radially
positioned with respect thereto, at the center of the tray. This
permits a locking device to be mounted upon the bracket adjacent to
the arm and bar connection, to engage the inside of the rail 22 and
lock the tray assembly to the table. The locking device
conveniently includes a U-shaped hook having a base 50 beneath the
underside of arm 45 with upstanding sides 51 at each side of the
arm, as in FIGS. 6 and 11, with each side having an obtuse angular
edge 52 facing the rail and a nose 53 at the upper end, to engage
the rail above its centerline. The sides of the hook are pivotally
connected to the arm by a rivet 54 extending through the sides
thereof to permit the latch to swing upwardly against the rail 22
to hold the tray in place, or to swing downwardly and out of the
way, as indicated in dotted lines in FIG. 6, to release the tray
from the table.
A latching means is associated with the hook to hold it in position
when it is against the rail. This latching means is conveniently
formed by a spring 55 formed of flat material and secured to the
base of the hook, beneath the arm, as by a rivet 56 of FIGS. 3 and
11. Spring 55 extends inwardly from the hook and then upwardly, to
embrace the bar 47 when the hook is in locking position. Spring 55
has an offset 57 adapted to engage a slot 58 formed in bar 47, as
in FIG. 6, by inward displacement of a tab 59 of the sidewall.
Offset 57 is adapted to snap into the slot to hold the hook against
the rail. The spring end 60, beyond offset 57, forms a single
finger latch which may be moved downwardly to pull the offset from
the hole and thereby release the hook, when the tray is to be
removed from the table. As in FIG. 12, a ramp-type depression 62,
formed by offsetting inwardly the inner wall of bar 47 and
corresponding in shape to the offset 57 of spring 55, may be
utilized in lieu of slot 58 of FIG. 6. In each instance, the
distance between the inner end of spring offset 57 and rivet 54, on
which the hook is pivoted, is greater than the distance between the
point of engagement of nose 53 with the rail and the rivet 54, and
preferably sufficiently greater that, in order to overcome the
locking force of nose 53, it will be necessary to exert a force
much greater than that which would be encountered in the normal use
of the table. Such forces may include a force directed outwardly
attempting to pull the tray away from the table; a force directed
upwardly beneath the tray, tending to cause the tray to be twisted
off the rail, but in this case the inner edge of rim 30 will act as
a fulcrum, increasing the resistance of the hook and particularly
nose 53 to dislodgment; or a force directed downwardly against the
tray, resistance to which will be assisted by the engagement of the
inner edge of rim 30 with the groove just beneath the tabletop. In
any event, the distance between rivet 54 and the inner end of
spring offset 57 may be increased considerably from that indicated
in FIGS. 2, 3 and 6. With the nose 53 engaging the rail above the
centerline of the latter, as indicated above, and the remainder of
each edge of the hook facing the rail spaced therefrom, the nose
provides a cam effect in locked position and also compensates for
any tolerance discrepancies in the size of the tubing, the location
of the hole for the rivet 54, or the like.
As hereinabove described, it is a very simple matter to mount a
tray T upon a table for which the tray is designed. The hook is
released from its latching position, while the tray is merely set
against the edge of the table with the rim 30 fitting into the
groove 23 at the edge of the table. The spring end may then be
moved upwardly to cause the hook to engage the inside of the rim
and to move the spring offset into slot 58 or depression 62 to lock
the latch in position. The removal of the tray from the table
merely involves pulling the spring down to the dotted position of
FIG. 6, to release the hook.
In the event that the trays are to be attached to the table more or
less permanently, the hook base 50 may be secured to arm 45 by a
screw 64, as in FIG. 13. For this purpose, spring 55 is omitted and
screw 64 inserted through the hole in base 50, normally occupied by
the rivet which attaches the spring to base 50, as in FIGS. 6 or
12, with this hole being enlarged, if necessary, and a
corresponding hole, but normally of smaller diameter, drilled in
the underside of arm 45, as screw 64 is conveniently a self-tapping
screw. Installation of the modification of FIG. 13 is accomplished
by loosening screw 64 so that the hook will pivot freely, placing
the tray in position, then pushing the hook toward rail 22 and
tightening screw 64 in the underside of arm 45. Removal of a tray
so installed, when desired, involves merely loosening of screw 64
until the hook will pivot away from the rail. To retain screw 64
upon removal, a fiber washer may be placed on the screw, on the
side of hook base 50 opposite the screwhead.
As will be evident from the foregoing, the objects and requirements
hereinbefore set forth are fulfilled to a marked degree. Thus, a
tray has been provided which readily converts an ordinary table
into a gaming table, particularly a round or circular table. When
the trays are formed as quadrants of appropriate curvature, as in
the preferred embodiment, a set of four trays will complete the
circumference of a table thereby forming a ledge all the way
around, in which chips, refreshment accessories or the like may be
placed. The tray itself may be formed of a relatively thin plastic,
so as to be light in weight, but reinforced and strengthened by a
metal bracket which is generally T-shaped thus providing a
reinforcement not only for the center, but also for each end of the
tray. The center arm of the bracket is particularly adapted to
carry a latching mechanism for engaging the inside of a depending
rail extending around the table, at the underside of the top. The
upper nose of the hook, pivoted on the center arm of the bracket,
provides a cam action and also accommodates variations in
manufacturing tolerances. When the hook is held in position by a
leaf spring having an offset which engages a slot, depression or
the like in the chordal bar of the bracket, the end of the spring
provides a handle for the spring used when the tray is installed or
removed. Or, the hook may be held in fixed position by a screw
attaching the hook base to the bracket arm, for a semipermanent
installation. Reinforcing ribs and flanges are also provided with
abutments for engaging a rail which is curved in transverse
section, such as being circular, while the radial walls for various
wells of the tray also reinforce the tray structure. Such a tray
is, of course, readily mounted on or removed from the table, but
when mounted on the table, provides a lightweight but strong and
rigid unit. The rim of the top of the inner wall of the tray is
also particularly adapted to engage a groove between the rail and
the top of the table, thus not only providing additional support
for the tray, but also adding further stability to the tray
structure. Although each tray has been described as preferably a
quadrant covering an arc of 90.degree. to permit four trays to
completely encircle a circular table, the extent of such a tray may
vary in any manner desired. Likewise, the number of wells in the
tray, hereinabove described as two at each side, may be increased
or decreased in any suitable manner.
Although a preferred embodiment of this invention and certain
modifications have been illustrated and described, it will be
understood that other embodiments may exist and that various
changes may be made therein, all without departing from the spirit
and scope of this invention.
