Description
BACKGROUND OF THE INVENTION
Overbed tables are conventionally based on the use of non-circular
metal tubing to prevent undesired swivelling of the table top with
respect to the leg portion thereof. Such metal tubing is a
specialty item and relatively expensive.
Furthermore, in known overbed tables, the supporting structure for
the table top which permits the same to be moved between horizontal
and tilted positions, does not provide stability to the extent
desired.
Accordingly, an object of this invention is to provide an improved
overbed table construction made from standard metal tubing of
circular cross section, including a leg design which insures
maximum stability in use and is locked against swivel
movements.
Another object of this invention is to provide an overbed table of
the character described, in which table top support means is
provided for securely holding the table top in its horizontal
position and securely holding said table top in its tilted
upstanding position as when the same is used as a book rest or the
like.
A further object of this invention is to provide an overbed table
of the character described, which includes improved means for
supporting the table top in its tilted position, such table top
supporting means being automatically movable to its operative
position when the table top is moved to its tilted position, such
supporting means being readily moved to its inoperative position
when the table top is moved from its tilted position to its
horizontal position.
Other objects of this invention will in part be obvious and in part
hereinafter pointed out.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, the overbed table embodying the
invention is generally indicated at 10. Table 10 comprises a base
portion generally indicated at 11; leg means generally indicated at
11A and extending upwardly from one end of base portion 11; table
top support means generally indicated at 11B which extends in
cantilever relation over base portion 11 and is mounted at one end
thereof to upper portions of leg means 11A.
The base portion 11 is formed of metal tubing of circular cross
section and comprises a longitudinally extending member 13
interconnected at the opposite ends thereof to a pair of
transversely extending members 14, 15. Casters 14A, 15A are mounted
on the opposite ends of members 14, 15.
The leg means 11A comprises a pair of metal tubing members 16, 17
of circular cross section; said members 16, 17 being secured at
their lower ends to member 13 by welding or the like. Member 17 is
located adjacent the juncture of members 13, 15, while member 16 is
located inwardly of member 17; the members 16, 17 being
interconnected at their upper ends by a brace plate 20 secured to
inner surface portions of said members 16, 17 by welding or the
like.
Leg means 11A further comprises a pair of metal tubing members 18,
19 arranged in telescopic relation to members 16, 17 respectively.
The members 18, 19 are interconnected at their upper ends by a
brace plate 20A secured therebetween. The parallel members 18, 19
are thus slidably related to members 16, 17 and may be locked as a
unit in selected positions by a set screw 16A mounted on member 16
and suitably threaded relation thereto.
The table top supporting means 11B comprises a J shaped member 22
formed of metal tubing of circular cross section and bent to shape.
Member 22 comprises a long arm portion 23 and a short arm portion
24. The free end of arm portion 23 is fixed to the upper ends of
leg members 18, 19 by welding or the like; the arm portions 23, 24
being located in a common horizontal plane.
The table top member 12 is of rectangular shape formed of wood or
other suitable material. Table top member 12 is tiltably mounted on
support means 11B. To this end, member 12 is rotatably mounted on
arm portion 24 by means of brackets 25 having semicircular
intermediate portions which encircle arm portion 24 and flanges 25A
which are fixed to the underside of table top 12 adjacent front
edge 12A thereof.
A metal edge plate 26 is fixed to arm portion 24 by plates 27 to
receive the inner edge 12A of table top member 12 when the same is
in a tilted position; the the top edge of plate 26 projecting above
the surface of the table top 12, to provide a book rest for a book,
not shown, positioned against the tilted top member 12.
Means is provided for supporting table top member 12 in its tilted
position. To this end, a bent rod member 28 is arranged for pivoted
movement between horizontal and upstanding positions. Member 28
comprises a portion 29 journalled in aligned openings 30 formed in
arm portion 23; a tubular spacer member 31 on the forwardly
projecting portion of member portion 29; successive, angularly
related portions 32, 33; with portion 33 terminating in a tip
member 34.
Member 28 is biased to its upright, table top supporting position,
as shown in FIG. 2, by a spring member 35 fixed at one end to arm
portion 23 at a point 35B spaced to the right of member 28, looking
at FIG. 2. The other end of spring member 35 is fixed to an
intermediate portion of member 28, as at 35A. A stop member 36 is
fixed to the underside of table top member 12, being located to
properly position member 28 with its tip 34 abutting the stop
member; whereby table top member 12 is positively supported in its
tilted position, see FIGS. 2, 4.
When table top member 12 is to be moved from its tilted position to
its horizontal position, member 28 is manually pivoted to the left,
looking at FIG. 2, which permits the now unsupported table top
member 12 to pivot about arm portion 24 toward its horizontal
position. When in such horizontal position, member 12 is securely
supported by the spaced arm portions 23, 24, leaving the table top
in a well stabilized condition.
To shift table top member 12 from its horizontal position to its
tilted position, it is only necessary to lift the outer edge
portion of table member 12 toward its tilted position, which
angular movement of member 12 allows biased support member 28 to
pivot to its upstanding, support position with its tip 34 abutting
stop 36.
It will be apparent that the arrangement of the telescoping tubular
members 16, 17; 18, 19 between base element 13A and arm portion 23
of support 11B, prevents any swivelling of table top member 12
relative to base portion 11. Further, the dual leg support 11A
increases the stability of the cantilevered support 11B and top
member 12 in respect to the device as a whole.
The location of support arm 24 adjacent table edge 12A optimizes
the position of the table top member 12 when the same is tilted
from its horizontal position about arm portion 24 as an axis. Thus,
table top edge 12A will not project toward the body of the user; as
is the case with conventional table tops which pivot about a
longitudinal axis medially of the side edges thereof. Further, the
arrangement of arm portions 23, 24 improves the stability of top
member 12 in its horizontal position, due to the location thereof
with respect to the transverse extent of member 12.
