EXTENSIBLE AND RETRACTABLE SUPPORT
Abstract
A shelflike supporting structure extensible into a generally
horizontal operating position and retractable into a generally
vertical position within a vertically oriented storage space within
a housing, through a vertically oriented opening in the housing.
The supporting structure is rotatable about a fore-and-aft axis
into its operating position after extension from the housing, and
may remain free to rotate about this fore-and-aft axis, or it may
be locked against such rotation. The supporting structure includes
a supporting member having an element mounted thereon for pivotal
movement about a pivot axis which is perpendicular to the
fore-and-aft axis and which is generally horizontal when the
supporting structure is in its operating position. This element may
be a gimbal ring which maintains a glass substantially vertical,
despite attitude changes of an airplane, for example, if the
supporting structure is free to rotate about the fore-and-aft axis.
The element mentioned may also be a stirrup on which a glass may be
seated, an ashtray cover, a brace for the supporting structure, and
the like. Also disclosed is an insulating collar for supporting a
glass in a ring.

retractable support and, more particularly, to a support of this
nature comprising: a housing provided therein with a generally
vertically oriented storage space and having at the front thereof a
generally vertically oriented opening communicating with the
storage space; a shelflike supporting structure of a size and shape
to pass through the opening into and out of the storage space when
the supporting structure is on edge in a generally vertical
position; and means mounting the supporting structure on the

generally horizontal operating position.
CROSS-REFERENCE TO RELATED APPLICATION
An extensible and retractable support of the foregoing general
nature is disclosed and claimed in my copending patent application,
Ser. No. 719,866, filed Apr. 9, 1968, now U.S. Pat. No. 3,497,076,
issued Feb. 24, 1970.
SUMMARY AND OBJECTS
A general object of the present invention is to provide an
extensible and retractable support of the foregoing general
character which embodies various improvements on the construction
disclosed in my aforementioned copending application.
More particularly, a primary object of the invention is to provide
a shelflike supporting structure of the foregoing nature which
includes a supporting member having an element mounted thereon for
pivotal movement about a pivot axis which is perpendicular to the
fore-and-aft axis of the supporting structure, and which is at
least generally horizontal when the supporting structure is in its
generally horizontal operating position.
An important object of the invention is to provide a construction
of the character outlined wherein the supporting structure is free
to rotate about its fore-and-aft axis and wherein the pivoted
element mentioned is a gimbal, preferably a gimbal ring, adapted to
support an article, such as a drinking receptacle or "glass," in a
substantially vertical position despite changes in the attitude of
the housing of the support. Such an embodiment of the invention is
ideally suited for use in an airplane since it will maintain a
glass substantially vertical even when the airplane is climbing at
a steep angle, descending, banking, and the like, which is an
important feature of the invention.
Another object of the invention is to provide an extensible and
retractable support wherein the pivoted element is a generally
U-shaped stirrup mounted on the supporting member for pivotal
movement about a pivot axis perpendicular to the fore-and-aft axis
and generally horizontal when the supporting structure is in its
operating position. Such a stirrup may be used in conjunction with
or independently of a gimbal ring as a support for an article such
as a glass, which is an important feature.
Still another object of the invention is to provide a construction
of the foregoing nature wherein the mounting means includes a
mounting member movable with the supporting structure in the
fore-and-aft direction, and wherein the stirrup is engageable with
the mounting member to serve as a brace for the supporting
structure. This arrangement of the components is particularly
useful where the supporting structure must carry a relatively heavy
article or articles, which is an important feature of the
invention.
Yet another object of the invention is to provide a construction
wherein the supporting member includes an ashtray and the pivoted
element is a cover or lid for the ashtray.
A further object is to provide an extensible and retractable
support of the foregoing nature which includes latch means for
latching the pivoted element in a retracted position with the
element substantially within the confines of the supporting member.
With this construction, the pivoted member is latched substantially
in the plane of the supporting member to facilitate retraction of
the supporting structure into its storage space within the housing,
which is an important feature.
An additional object of the invention is to provide a construction
wherein the supporting structure and the mounting member include
alternatively usable interengageable means for releasably holding
the supporting structure in its generally horizontal operating
position or in its generally vertical position. In the former
instance, the supporting structure is locked in its generally
horizontal operating position against rotation about its
fore-and-aft axis when this is desired. The alternative
interengageable means locks the supporting structure in its
generally vertical position against rotation about its fore-and-aft
axis relative to the mounting member, thereby facilitating movement
of the mounting member and the supporting structure between the
retracted and extended positions of the supporting structure.
An object related to that set forth in the preceding paragraph is
to provide a construction wherein the alternatively usable
interengageable means are activated simply by reversing the
moveable mounting member.
Yet another object is to provide latch means for latching the
supporting structure in its retracted and extended positions.
Still another object of the invention is to provide a supporting
collar for a downwardly tapered glass which is so shaped that it
contacts the glass at the upper and lower ends of the collar only,
thereby providing an annular insulating clearance between the
collar and the glass intermediate the upper and lower ends of the
collar. With this construction, the collar may be seated on a
supporting ring, or equivalent, forming part of the retractable
supporting structure.
The foregoing objects, advantages, features and results of the
present invention, together with various other objects, advantages,
features and results thereof which will be evident to those skilled
in the art to which the invention relates in the light of this
disclosure, may be achieved with the exemplary embodiments of the
invention illustrated in the accompanying drawings and described in
detail hereinafter.

DESCRIPTION OF EXEMPLARY
EMBODIMENT OF INVENTION
FIGS. 1 through 6
Referring initially to FIG. 1 of the drawings, illustrated therein
to show one possible application of the present invention is an
aircraft seat 20 provided with an arm 22 having an extensible and
retractable support 24 of the invention incorporated therein. The
support 24 is shown for convenience as including an outer housing
26 which contains an innerhousing 28 and which constitutes part of
the arm 22 of the seat 20. However, it will be understood that the
innerhousing 28 may be installed in a suitable cavity, not shown,
in the arm 22. Also, other variations are possible.
The innerhousing 28 is provided therein with a generally vertically
oriented storage space 32 and is provided at the front thereof with
a generally vertically oriented opening 34, FIG. 5, communicating
with the storage space.
The extensible and retractable support 24 of the invention includes
a shelflike supporting structure 36 of a size and shape to pass
through the opening 34 into and out of the storage space 32 when
the supporting structure 36 is on edge in a generally vertical
position, as shown in FIGS. 5 and 6.
A mounting means 40 connects the supporting structure 36 to the
housing 28 for fore-and-aft movement of the supporting structure
into and out of the storage space 32 through the opening 34 between
retracted and extended positions, and for rotational movement about
a fore-and-aft axis between such generally vertical position and a
generally horizontal operating position, FIGS. 1, 2 and 3.
The mounting means 40 includes a blocklike mounting member 42 which
carries the supporting structure 36 and which is movable therewith
relative to the housing 28 in the fore-and-aft direction. In the
particular construction illustrated, the mounting member 42 is
slidable in the housing 28, but, if desired, the mounting member
may be equipped with rollers or wheels engageable with the top and
bottom walls of the storage space 32.
A latch means 44 carried by the mounting member 42 and engageable
with the housing 28 latches the supporting structure 36 in its
retracted and extended positions. In the construction illustrated,
the latch means 44 comprises a plunger-type latch 46 extending
transversely through and carried by the mounting member 42, and
biased by a spring 48 into either of two holes 50 and 52 in a
sidewall of the housing 28. When the latch 46 is in the hole 50, it
retains the supporting structure 36 in its retracted position. When
in the hole 52, it retains the supporting structure in its extended
position. The latch 46 extends laterally outwardly through a
fore-and-aft slot 54 in the outer housing 26, and terminates in a
knob 56.
The mounting member 42 is provided with a shoulder 58 engageable
with a stop pin 60 carried by the housing 28 to prevent inadvertent
withdrawal of the mounting member 42 from the housing 28. However,
the pin 60 may be removed in any suitable manner to permit such
withdrawal if desired. The opposite end of the mounting member 42
is provided with a shoulder 62 which is also engageable with the
stop pin 60 to prevent complete withdrawal if the position of the
mounting member 42 within the storage space 32 is reversed by
rotating it 180.degree. in a vertical plane, as shown in FIG. 7.
The purpose of such a reversal of the position of the mounting
member 42 will be discussed hereinafter in conjunction with the
embodiment of FIGS. 7 and 8.
The supporting structure 36 includes a supporting member 64, best
shown in FIG. 6, provided with a shaft 66 which extends rearwardly
through the mounting member 42 along the fore-and-aft axis of the
extensible and retractable support 24. Slipped over the rearwardly
projecting end of the shaft 66 is a coil spring 68 seated in a
transverse notch 70 in the rearward edge of the mounting member 42.
The other end of the spring is seated against a washer retained by
a nut 72 threaded on the shaft 66.
When the supporting structure 36 is in its generally vertical
position, as shown in FIGS. 5 and 6, rearwardly projecting tongues
74 on the rear edge of the supporting member 64 are disposed in
complementary grooves 76, FIG. 4, in the forward edge of the
mounting member 42. This tongue-and-groove connection retains the
supporting structure 36 in its generally vertical position relative
to the mounting member 42 to facilitate insertion of the supporting
structure into the storage space 32. The spring 68 is slightly
stressed under such conditions to maintain the tongues 74 in the
grooves 76. The rearward edge of the mounting member 42, as viewed
in FIGS. 1 to 6, is provided with similar grooves 78 which receive
the tongues 74 when the mounting member 42 is reversed in position,
as hereinbefore mentioned, and as discussed in more detail
hereinafter in connection with the description of the embodiment of
FIGS. 7 and 8.
When the supporting structure 36 has been moved forwardly into its
extended position, it can be rotated 90.degree., about the axis of
the shaft 66, into its generally horizontal operating position by
compressing the spring 68 sufficiently to permit disengagement of
the tongues 74 from the grooves 76. As will be apparent, this may
be accomplished by pulling forwardly slightly on the supporting
member 64. The tongues 74 on the supporting member 64 are spaced
apart, as best shown in FIG. 4, so that, when the supporting
structure 36 is in its operating position, it is free to pivot
about the fore-and-aft axis of the shaft 66. The characteristics
and adjustment of the spring 68 are such that it is unstressed, or
substantially unstressed, under these conditions to permit the
supporting structure 36 to pivot freely about the axis of the shaft
66.
Thus, with the construction shown in FIGS. 1 to 6 of the drawings,
the supporting structure 36 is releasably latched to the mounting
member 42 by the tongues 74 and the grooves 76 when the supporting
structure is in its generally vertical position. However, when the
supporting structure 36 is in its generally horizontal operation
position, it is free to pivot about the fore-and-aft axis relative
to the mounting member 42.
Considering the supporting structure 36 in more detail now, it is
shown as comprising a generally rectangular frame the rearward end
of which is carried by the shaft 66. Disposed within the supporting
member 64 is a gimbal ring 80 supported by pivot pins 82 connected
to the sides of the supporting member and providing a pivot axis
which is perpendicular to the fore-and-aft axis and which is at
least generally horizontal when the supporting structure 36 is in
its generally horizontal operating position.
The gimbal ring 80 may be employed to support a downwardly tapered
drinking glass merely by seating such glass therein in a manner
which will be apparent, but which is not specifically shown. As
will be clear from FIGS. 2 and 3, pivoting of the supporting member
64 about the axis of the shaft 66 and pivoting of the gimbal ring
80 about the axis of the pivot pins 82 will cause such a glass to
remain substantially upright at all times despite changes in the
longitudinal attitude of the airplane, FIG. 2, or changes in the
lateral attitude thereof, FIG. 3. Thus, even if the airplane climbs
or descends at substantial angles, such a glass will remain
essentially upright at all times, which is an important feature of
the invention.
In addition to the gimbal ring 80, the pivot pins 82 carry another
pivoted element having the form of a generally U-shaped stirrup 84
in which a glass 86 too small to be carried by the gimbal ring 80
directly may be seated, as shown in FIGS. 1, 2 and 3. The glass 86
supported by the stirrup 84 will also remain substantially upright
at all times despite wide variations in the longitudinal and/or
lateral attitudes of the aircraft.
The extensible and retractable support 24 includes latch means 88
for releasably latching the stirrup 84 in a retracted position
within the rectangular frame forming the supporting member 64, as
shown in FIG. 6 of the drawings. The latch means 88 comprises
simply a latch 90 of the plunger type biased by a spring 92 into a
recess 94 in the base of the stirrup. The arms of the stirrup are
provided with slots 96 receiving the pivot pins 82 and permitting
sufficient sliding movement of the stirrup relative to the
supporting member 64 to permit the supporting member to move into a
retracted position within the confines of the supporting member.
The latch 90 is provided with a knob 98 complementing the forward
end of the supporting member 64, as best shown in FIG. 5.
The ability to latch the stirrup 84 in its retracted position with
the supporting member 64 in the manner indicated is an important
feature because it facilitates rearward movement of the supporting
structure 36 into its retracted position within the storage space
32, it merely being necessary to properly align the gimbal ring 80
so that it remains within the confines of the supporting member 64
also. Thus, there is virtually no tendency for any part of the
supporting structure 36 to hang up when retracting the supporting
structure, which is an important feature. (If desired, the length
and stroke of the plungerlike latch 90 could be increased to latch
the gimbal ring 80, as well as the stirrup 84.)
EXEMPLARY EMBODIMENT OF INVENTION
FIGS. 7 and 8
Illustrated in these figures is a retractable and extensible
support 102 which utilizes most of the same components as the
support 24, identical components being designated by identical
reference numerals. The support 102 differs in that it includes a
modified supporting structure 104 and in that the mounting member
42 is reversed in position, from the position shown in FIGS. 1 to
6, by rotating it through 180.degree. in a vertical plane. Thus,
the notch 70 is located in what, in this embodiment, is the forward
edge of the mounting member 42.
The supporting structure 104 includes the same supporting member 64
having its shaft 66 rotatable relative to the mounting member 42 in
the same way as in the embodiment of FIGS. 1 to 6. In this case,
however, the open rectangular supporting member 64 contains a
complementary ashtray 106 which fits within the supporting member
relatively closely and which is held therein by two pins 108
occupying the same holes as the pivot pins 82 of the previous
embodiment. The ashtray 106 is provided with a pivoted cover or lid
110 connected to the body of the ashtray by a pivot means 112 which
is perpendicular to the fore-and-aft axis of the shaft 66 and which
is generally horizontal when the supporting structure 104 is in its
generally horizontal operating position. The cover 110 is spring
biased upwardly into an open position, shown in broken lines in
FIG. 8, and is provided with a recess 114 engageable by the latch
90 to secure the cover in its closed position, shown in full lines
in FIG. 8.
The rearward edge of the supporting member 64 fits into the notch
70 in the now forward edge of the mounting member 42 to prevent
pivoting of the supporting structure 104 about the fore-and-aft
axis, such pivoting being unnecessary in the case of the ashtray
106. It will be noted from FIG. 7 that the spring 68 is compressed
to hold the rearward edge of the supporting member 64 in the notch
70.
With this construction, if it is desired to empty the ashtray 106,
this can be accomplished readily by pulling forwardly on the
supporting member 64 to withdraw its rearward edge from the notch
70, and then rotating the supporting member through 180.degree.
about the axis of the shaft 66, thereby inverting the ashtray.
Releasing the cover 110 will then permit automatic dumping of the
ashtray into a suitable container, not shown.
EXEMPLARY EMBODIMENT OF INVENTION
FIGS. 9 and 10
Illustrated in these figures is an extensible and retractable
support 120 which includes a supporting structure 122 similar to
the supporting structure 36 and which has the mounting member 42 in
the same position as shown in FIGS. 7 and 8. The supporting
structure 122 includes the gimbal ring 80 carried by its pivot pins
82 and includes a stirrup 124 very similar to the stirrup 84, and
capable of being latched in a retracted position in the same manner
as the stirrup 84.
The gimbal ring 80 may support a glass, or the like, by seating it
directly on the gimbal ring in the manner hereinbefore described in
connection with the embodiment of FIGS. 1 to 6. Alternatively, a
glass, not shown, may be seated on the stirrup 124 in the same
manner as shown in FIGS. 1, 2 and 3.
Alternatively, the stirrup 124, instead of being latched in its
retracted position, or being used in a depending position to
support a glass, may be pivoted to a third position, as shown in
FIG. 10, to seat against the mounting member 42, which, in this
case, is shown as provided with an extension 126 against which the
stirrup is seated. With this construction, the stirrup 124 acts as
a brace to permit the supporting structure 122 to carry more weight
than is possible with the embodiments previously described. The use
of the stirrup 124 as a brace in this manner is particularly useful
where the supporting structure 122 is required to carry a heavy
article, or where the extensible and retractable support 120 is
incorporated in a larger scale version intended for heavier
loads.
The stirrup 124 engages a surface 128 of the extension 126 having a
slope such that the weight of a load carried by the supporting
structure 122 maintains the stirrup 124 seated against the surface
128.
In the embodiment under consideration, the supporting member 64 is
latched against rotation about the fore-and-aft axis by the
positioning of the rearward edge of the supporting member in the
notch 70. Consequently, the gimbal ring 80 can pivot only about the
axis of its pivot pins 82. If, however, it is desired to maintain
the gimbal ring 80 substantially horizontal, as in the case of the
embodiment of FIGS. 1 to 6, this may be accomplished readily by
utilizing the mounting member 42 in the same position as it
occupies in FIGS. 1 to 6, instead of the reversed position of FIGS.
7 to 10.
Another feature of the present invention which is illustrated in
FIGS. 9 and 10 resides in the provision of a supporting collar 130
which enables the ring 80 t0 support a glass 132 having such a
small diameter at its upper end that it would otherwise pass
through the ring, and having a height such that it cannot be
supported on the stirrup 124 without the possibility of tipping
over. It will be noted that the collar 130 engages the glass 132
near its top so that the center of gravity of the glass and its
contents is near or below the fore-and-aft axis, and the transverse
axis provided by the pivot pins 82, to achieve stability.
Another feature of the collar 130 is that its inside diameter at
its upper and lower ends are equal to the outside diameters of the
glass 132 in corresponding upper and lower zones, and that the
inside diameter of the collar is greater than the diameters of the
glass intermediate the upper and lower ends of the collar. This
effect is accomplished by providing the collar at its lower end
with an internal annular rib 134. The result of this construction
is an annular clearance 136 between the collar 130 and the glass
132 throughout most of the length of the collar. This annular
clearance 136 provides an annular dead air space for insulating
purposes. Thus, the person using this embodiment may pick up the
glass 132 by the insulating collar 130 to prevent injury or
discomfort in the event the glass contains an extremely hot
liquid.
