MULTI-PURPOSE BED TABLE MOVABLE BED'S LENGTH UNDER PATIENT'S
CONTROL
Abstract
The apparatus' is characterized by a table positioned above a
bed yet not resting thereon, which table is equipped with legs on
each side of the bed, which legs are attached to the said table at
their upper extremity and having rollers on their lower ends to sit
on and move over the floor; the bed has at least one side rail that
has a length-wise open channel throughout substantially its length,
a flexible cable or substantial cord that is affixed at
approximately the mid-height of legs to the legs, which cable
passes over a pulley affixed to one end of the bed and over another
pulley at the other end of the bed. The movement of the table
lengthwise of the bed is controlled by, preferably, a motor with a
shaft and a wheel over which the flexible cable passes to be moved
one direction or the other. Yet other means can be used, such as an
additional pulley or more, over which the cable passes, with pull
ends on the cable to be moved one down and the other down when the
other is in an up position.

Description
THE OBJECTS OF THE INVENTION
This invention relates to a bed and a table positioned above it but
not resting upon it and free to move with a very minimum of effort
by a hospital's patient or the attending nurse, etc., either up the
length of the bed or down its length, the table being supported by
legs affixed to it on each side thereof, whose lower ends are
equipped with rollers to turn and move upon the surface of the
floor.
A further object of this invention is to provide a combination of a
bed, and a table above the bed, completely under the control of the
patient in the bed or the attendant, which table is not supported
by the bed or any portion of the bed, but by legs on each side of
the bed, whose upper respective ends are spaced and affixed to the
table on each side, and whose terminal lower ends are provided with
rollers that move over the surface by contact with it; the movement
of the table length-wise of bed is accomplished by means of a cable
that is attached to legs of the table, which cable passes too over
spaced pulleys affixed to the bed at the ends of the latter, the
cable being movable, hence the table by the patient, with a very
mimimum of effort by means associated with the cable.
Still a further object of this invention is the combination of a
table and a bed, the table being positioned above the bed but not
supported by it, but supported by legs on each side of the bed, the
upper ends of which legs are affixed to the sides of the table and
the lower extremity of which legs is provided with a roller, which
rollers move by contact with the floor, whereby the table is
movable up and down the bed's length, the movement being
accomplished by a cable affixed to the front and rear legs on a
side of the bed, and extending over rollers at the bed's two length
ends and through a channel in a side rail of the bed; the movement
is brought about preferable by a motor with a shaft and wheel
thereof, over which wheel's channel the cable passes, the motor
rotating in both directions moving the cable thus the table
lengthwise up and down at the will of the patient or the
attendant.
It is still yet another object of this invention to provide that
type of table in combination with a bed, which table has a top that
is hinged to the base portion of it, which base portion has not
only sides but also dividers, thus providing space areas for such
things as comb and brush, tooth-paste, paper handkerchiefs, `beauty
aids`, eye glasses, etc.
The invention possesses many other advantages in addition to the
objects and advantages that have been recited above; ; these will
become readily apparent from a of one embodiment shown in the
accompanying drawing, that forms a part of this application for
letters patent. This embodiment will be described in detail now. It
is, however, to be understood that this attached description is not
to be taken in a limited sense, since it is to the appended claims
of the invention that a person must look for the scope of the
invention.
THE DESCRIPTION OF THE INVENTION VIA AN EMBODIMENT
FIG. 1 is a side elevation of a bed with a table and supporting
means for the latter movable longitudinally of the bed.
FIG. 2 is a cross-sectional view, taken along lines 2--2 of FIG.
1.
FIG. 3 is a detached side plan view of the action producing members
at the foot of the bed, the bed table and most of the legs being
omitted.
FIG. 4 is a detached side plan view of the action producing members
at the head of the bed, including the electric motor as power
source.
Like reference numerals indicate like parts throughout the several
views.
Referring to FIG. 1, the table indicated by the numeral 1, is shown
mounted upon four legs, there being two on each side of the table,
at the respective top ends; the legs bear the numeral 2. At the
lower end of each leg is a roller 3, which is mounted in a
conventional manner, utalizing the hollow part of said legs. The
rollers, needless to state, by friction due to contact with the
floor enable the supported table 1 to be moved. As seen from FIG.
2, the legs 2 clear the sides of the bed to avoid friction that
would impede movement of the said supporting legs. Viewing this
same figure, it is seen that the bed, itself, has rollers,
indicated by numeral 4, as is true of many conventional beds, be
they in hospitals or otherwise, forming per se, no part of the
novelty of this invention. This figure shows a mattress 5 on
horizontal supporting slats 6 of the bed. FIG. 1 shows in dotted
lines the supported table and its legs moved to the lower end of
the bed. In this embodiment shown in the drawing the bottom 7 of
the table 1 is higher in elevation than the foot of the bed, this
enabling the table with its movable supporting legs to be more
readily positioned in relation to the bed, per se, i.e. lifting is
thereby avoided in positioning the table. Both from FIGS. 1 and 2
it can be seen that the movement of the table with reference to the
bed is longitudinal of the bed but clearing the bed
nevertheless.
It is an objective, a fortiori, of this invention to enable a
patient to move with a very minimum of physical effort, thus
exertion, the supporting table with no danger of upsetting any
portion of the contents of a tray of food or glasses containing
liquid, and other things placed upon the table by nurses or
hospital attendants. How this is accomplished will be set forth now
in detail with reference to the drawing. Looking at FIGS. 1, 2 and
3, it will be seen that attached to the foot 8 of the bed is a
L-shaped flange, numbered 9, to which in turn is fastened a
longitudinal rail 10. From FIG. 2 it will seen that said rail 10
has a longitudinal slot 11 therein. Like the rail itself, the slot
extends the entire length of the rail, the purpose of which will be
elucidated. As seen from FIG. 3 a U-shaped bracket 12 is attached
to the lower end of the bed. Rotatably affixed to the sides of this
bracket is a pulley 13 with a centrally positioned groove in its
exterior surface, in which a cable 14 moves upon rotation of the
pulley. This end of the cable 14 is attached by a snap-on buckle 15
to the eye of a bolt 16 extending through table leg 2 nearest the
end of the bed. As seen from FIG. 4 the other end of the cable is
attached to the leg nearest the head of the bed by a snap-on buckle
17, which holds to the eye of a bolt 18 that extends through this
last mentioned leg. Only the front run portion of cable 14 and its
connections to the two respective table legs is shown in the
drawing. But obviously the back run of this cable parallels the
front run except for connections to the front table legs; the two
legs on the back side need not be connected to a cable in order for
the table to move longitudinally. Four table legs are needed for
the complete, effective support of the table, and these are
attached at their upper extremities to the said table. The cable,
inasmuch as the pulley at the lower end of the bed and the pulley
at the head end of the bed, identified by numerals 13 and 19, are
within the slotted longitudinal rail 10, would not pose any danger
to people from contact therewith, such as hospital workers or
visitors of patients in the hospital room. Rail 10 is attached by a
L-shaped bracket 20 to the head 21 of the bed. There is an electric
motor 22, which is affixed to the head of the bed, in a
conventional manner. Electric current carrying wires 23 are shown
in FIG. 1. The wires, per se, are not exposed but are encased as
shown in FIG. 1. Projecting from the top portion of this electric
motor is represented pulley 19 on a shaft that rotates, 19'. Like
pulley 13 referred to above it too has a groove or channel on its
exterior cylindrical surface for the contacting cable 14.
From FIG. 1 it will be seen that the electric wire carrying cable
has a plug 24 at its extremity for insertion in a wall socket. An
electric line 25 runs from the electric motor, and to its extremity
there is attached a push button type activator with several
buttons, numbered 26. Assume that a tray of food has been placed by
a hospital employee upon table 1 at the location of the latter
shown in dotted lines in FIG. 1; the patient need but to push one
of the buttons in activator element 26, and immediately the motor
22 will start, causing the pulley 19 to turn, thus the cable 14 to
move in the direction toward the head of the bed. Because the table
is affixed to the lower and upper leg pair, the table 1 moves up
toward the patient's body until he or she pushes the inactivating
button. When the patient has finished the meal he or she pushes
another button that will reverse the rotation of the pulleys, thus
causing the table to move longitudinally to the position shown in
the dotted lines in FIG. 1. It is believed that this assembly above
described has advantages over tables supported by the bed itself
through members attached to the bed for this purpose.
Whereas the preferred force for moving or turning the pulleys,
which cause the cable to move up the length of the bed or to its
lower end, carrying the table longitudinally with it, is an
electric motor, hand force can be used instead. In this situation
additional pulleys would be needed to bring the ends of the cable
with handles thereon to a locus near the patient, so that he or she
could pull one end of the cable to effect movement of the table
longitudinally toward the patient, and the other end of the cable
to cause the table to move toward the lower end of the bed. This is
not shown in the drawing, however, but arrangement of pulleys to
achieve movements by handles on cable's ends is known, such as in
moving curtains in houses.
Reference has been made above to tables by numeral 1. For the
convenience of patients, particularly female patients, the table
can be more than a simple flat surface with little depth. By
utalizing enclosed yet accessable space within the table and below
the flat surface, the table can be caused to replace a night stand
conventionally used to hold the supplies of the patient. To this
end such an embodiment will be briefly described. The top, numbered
27, can be hinged, as shown in FIG. 5. The lower portion 28 of such
table can have a plurality of compartments 29, for the storage or
keeping of such things as tissue paper, shaving instruments and
brush or spray can of soap, eye glasses, `make-up` accessories for
women, etc. A mirror may be affixed to the rear surface of the
hinged top of the table. It is advantageous to have a table that
has a rounded surface that approximates the contour of the
midsection of a person rather than a straight line.
The foregoing description and the drawing to which the wording
refers discloses a preferred embodiment of this invention; but it
will be understood that this disclosure is merely illustrative, and
that changes may be made within the scope of the following
claims.
