Description
This invention relates generally to book supporting devices and in
particular to an improved support adapted for use by individuals
when in a reclining position.
Various devices have been utilized to enable bedridden persons to
maintain reading material in position for reading when in a supine
or semisupine position. The majority of these devices have such a
degree of instability that they can be easily dislodged from the
bed surface. Further difficulties have been experienced with the
complexity of adjusting the device for the proper angle relative to
the person's position.
Therefore it is an object of this invention to provide a simple,
novel and inexpensive bed-supported reading device adapted to be
maintained at the proper angle to a supine person.
Another object of this invention is to provide a bedsupported
reading device being fully adjustable with respect to each of the
supporting legs.
A further object of this invention is to provide a book supporting
device wherein the reading material is maintained by gravity on a
transparent surface.
Other objects of this invention will in part be obvious and will in
part appear hereinafter.
Broadly stated, one feature of this invention is to provide a book
supporting device for use by persons in bed having a simple tubular
frame construction with a unitary transparent book supporting shelf
suspended thereon with each of the leg members adjustable as to
length to conform to any desired position.
To the accomplishment of this and the foregoing related objects,
the present invention then consists of the means hereinafter fully
described and particularly pointed out in the claims, the annexed
drawings and the following description setting forth in detail
certain means in the carrying out of the invention, such disclosed
means illustrating, however, but one of the various methods by
which the principle of the invention may be employed.
IN THE DRAWINGS
FIG. 1 is a view in side elevation of the device,
FIG. 2 is a view in rear elevation,
FIG. 3 is a view in perspective of the device,
FIG. 4 is a view in perspective, partly in section, of the tongue
and groove joint of the frame, and
FIG. 5 is a view in perspective of the clamping mechanism for
maintaining the supporting legs within the tubular frame.
Reference is now to be had to the drawings wherein an illustrative
embodiment of the supporting device, a construction made in
accordance with the present invention and designated by the
reference numeral 10, is shown.
Referring to FIGS. 1, 2 and 3, there is shown a pair of straight
hollow tubular side members, 12, laterally spaced from each other
and having their lower ends, 14, joined by a laterally extending
base member 16. The base member 16 has a diameter less than the
tubular side members 12 and has arcuate terminations 18 allowing a
portion 20 of the base member 16 to slide freely within the end 14,
of the tubular side members 12. The upper end 22 has a curvature 24
formed thereon defining an oblique angle and is joined to an
obliquely extending rear tubular member 26 by means of a pivot
joint 28, as shown in FIG. 4.
Referring to FIG. 4, the pivot joint comprises a tongue member 30
rigidly fixed in the rear tubular member 26 by pin 32 and having
one end 34 extending into the upper end 22 of the tubular side
members 12, in such a manner that a pin 36, extending through the
side walls and an aperture 38 in the end 34 will allow a pivotal
action therearound. As shown in FIG. 4, the lower portion of the
side wall 40 is chamfered to allow free pivotal action of the rear
tubular members as shown in the dotted lines and designated by
numeral 26a.
The rear tubular members 26 have a configuration as shown in FIGS.
2 and 3 where a pair of bends 41 are formed therein defining a
lateral distance between each of the parallel rear tubular members
26 greater than the length of the base member 16, for a purpose to
be set forth more fully hereinafter.
Each of the rear tubular members 26 have leg members 42 with
ferrules 44 at the distal ends thereof, the leg members having a
diameter less than the interior of the tubular members 26 and
adapted for sliding telescopic engagement therein.
Clamp members 46 as shown in FIG. 5, comprising a circular band 48,
compressible in response to the action of a springloaded actuating
member 50, are fitted around each of the lower ends of the rear
tubular members 26 so as to hold the leg members 42 at a fixed
position within the tubular members 26.
The book support member 52 comprises a unitary transparent plastic
member 53 extending between the parallel side tubular members 12
and supported therebetween by screw members 54 extending through
blocks 56 attached to the surface of the plastic member 53 and into
the side tubular members 12. A shelf portion 58 is formed at the
lower edge 60 thereof, having a width sufficient to accommodate a
book 62. Cutout portions 64 extend upward from the lower edge 60
and toward the side edges 66 of the plastic member to allow access
from one surface of the plastic member 53 to the other.
The purpose of having the rear tubular members extending outward of
the lateral distance defined by the base member 16 is to provide
complete freedom of the shoulders and arms of the reader while the
device is in position.
In this manner, a book 62, placed on the surface of the transparent
plastic member 53, can be read by the person through the
transparent plastic member 53 and the cutout portions 64 allow easy
access to the book for the purpose of turning the pages.
While there have been described herein what I at present consider
preferred embodiments of the invention, it will be obvious to those
skilled in the art that modifications and changes may be made
therein without departing from the essence of the invention. It is,
therefore, to be understood that the exemplary embodiments are
illustrative and not restrictive of the invention, the scope of
which is defined in the appended claims, and that all modifications
that come within the meaning and range of equivalency of the claims
are intended to be included therein.
