Description
SUMMARY OF THE INVENTION
The invention is a food serving tray mounted on pivot arms at the
back of a chair or seat and, more particularly, an aircraft
seat.
In a preferred form of the invention as described in detail herein,
the tray is shown mounted to a seat having a back recess. The tray
and pivot arms are collapsible into a position in the recess so
that the tray is flush with the back of the seat. A covered vanity
mirror is provided on the underside of the serving tray. The cover
is hinged so that it can be swung outwardly to form a tray or
platform. The vanity mirror is also hinged to the underside of the
food serving tray.
The adaption of the invention for use with aircraft seats is
particularly important. A large number of passengers on aircraft
are served by stewardesses under relatively restricted conditions.
To eliminate the need for handling of any articles, such as food
trays by the stewardesses, is an important objective to be realized
and is one of the objectives of this invention. The tray is very
simply swung out into position for use. This can be done by the
passenger. When it is not needed, the tray can be moved into
collapsed position completely out of the way. It is useful
repeatedly.
Another object of the invention is to realize this capability that
the tray is adjustable to its position for use by the passenger and
is completely collapsible into an out-of-the-way position. The
vanity mirror on the underside of the tray adapts the assembly for
use particularly by women passengers in providing a conveniently
available mirror with associated tray for placing cosmetics and the
like. Another object of the invention is to realize this capability
in the assembly.
Another object is to make possible a tray assembly as described
which is economical to fabricate, manufacture, and install and
which does not require maintenance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, numeral 10 designates a conventional
aircraft seat having a back 12 in which there is provided a recess
14 having a shape as shown to accommodate the collapsed position of
the tray. The tray is designated at 20, and its construction will
be described in detail presently. Preferably, at inside corners of
the tray are indentations or recesses 22 and 22'. The swing arms
are attached to the tray at these positions. The pivoted swing arms
are designated at 24 and 24'. They are pivotally attached to the
lower part of the back of the chair at the extremities of recess
14.
The arms 24 have angular end portions designated at 28 and 28'
which are pivotally mounted on the ends of a transverse shaft
extending through the lower part of the seat as designated at 32 in
FIG. 2. The arm extensions 28 and 28' are pivoted on the ends of
this shaft. Each of these extension can come into engagement with a
stop screw as shown at 34 and 34' which holds the swing arms in the
desired position of the tray in which it is horizontal as may be
seen in FIG. 3 and positioned outwardly from the back of the chair.
The inside corners of tray 20 are pivotally mounted on pivot bolts
extending from the extremities of the arms 24 and 24' as may be
seen in FIGS. 3, 4, and 5, one of said pivot bolts being designated
at 40 in the figures.
As may be seen in FIGS. 4 and 5, at the position of recess or
indentation 22 on the table 20, there is an extending cylindrical
stop member 44. When table 20 is in horizontal position, this stop
member comes into engagement with inside surface 46 at the end of
arm 24 which holds table 20 in the horizontal position preventing
it moving any further in a clockwise direction. When the table
collapses, this stem can move into an arcuate groove 48 in arm 24.
This construction is the same on both sides of the tray.
FIGS. 6 through 10 show the construction of the tray and vanity
mirror in more detail. Tray 20 itself as may be seen in FIG. 8 has
a recess 50 in the back which can receive vanity mirror 52 in a
flush position in the recess. The vanity mirror is hinged as
described. Numeral 54 designates a hinged cover which can be swung
out to form a platform as shown at FIG. 8 and swung in to a
position covering the mirror. The cover 54 has a grasp 56 adapted
to be received in cutout 58 in the bottom of tray 20.
Tray 20 is shown in cross section in FIGS. 6, 7, and 9. At the
upper part of recess 14 is another recess 58 of less depth.
Pivotally mounted therein is a latch button 60 on a stem 62 which
can be rotated to engage with an upper surface 64 of the tray 20
and to be held at the position of an indentation 66 as shown.
In the exemplary form of the invention, the tray may be formed of
relatively thin rigid plastic material or other material formed in
a configuration as may be seen in FIG. 6. In the preferred form the
tray is formed in two fabricated laminations bonded together as
designated at 70 and 72 as may be seen in FIG. 1. The lower
lamination or formed part provides the recess 50 for the vanity
mirror. Typically, if desired, the top may be covered by a thin
layer of other material, such as formica with colored bindings or
edge strips around the peripheral edges of the tray.
Mirror 52 may comprise a relatively stiff, thin backing sheet 74
having the mirror surface 76 attached to it. Member 76 is attached
to the bottom of recess 50 by way of a piano hinge 80 secured to
the bottom of the recess as shown at 82 in FIG. 6. The securement
includes stiffening strip 84. This construction is shown in more
detail in FIGS. 9 and 10. The hinge pin of the hinge is designated
at 86 in FIG. 9.
Near the bottom of recess 50 is a small secondary recess 88 forming
a shoulder as shown including a ledge 90. A mirror cover or
platform is hinged to ledge 90 by way of a piano hinge 92 having a
hinge pin 94. In the exemplary form of the invention, the cover 54
is preferably formed from relatively thin sheets or pieces of stiff
cardboard or plastic as designated at 96 and 98 which may be
covered with a suitable thin, colored material such as vinyl or the
like. The upper piece 98 has a continuous peripheral edge rib. The
part on the front edge is designated at 100, and the part on the
rear edge is designated at 102. The leaves of the piano hinge 92
extend between parts 96 and 98 with stiffening members being
provided as designated at 104 and 106.
FIG. 12 shows a modified form of the invention wherein mirror 110
is hinged directly to the back of seat 10 rather than to the
underside of the tray. The mirror is hinged at 112 and is covered
by the tray when it is collapsed.
From the foregoing, those skilled in the art will readily
understand the nature and construction of the invention and the
manner in which it achieves the objects and purposes as set forth
in the foregoing. It will be understood that the tray is completely
collapsible to a flush position in the recess in the back of a
chair. The mirror and its cover can be collapsed into flush
position into the recess in the bottom of the tray and the cover
can be swung out into a position to form a platform as shown in
FIG. 8 with the mirror moved outwardly about its hinge to an
appropriate position for use. Although a specific construction of
an exemplary form of the tray and mirror have been shown in detail,
it should be understood that other types of construction of the
tray and mirror may be embodied in the invention as well as the
specific types of pivotal support allowing its collapsing movement
into flush position.
The foregoing disclosure is representative of preferred, exemplary
forms of the invention and is to be interpreted in an illustrative
rather than a limiting sense, the invention to be accorded the full
scope of the claims appended hereto.
