Utility desk

A portable utility desk for bed-patient and other uses including a flat, rectangular surface having a semicircular notch on one side thereof for adapting to the body of the user and providing for attachment of legs to the surface to be usable in a multiplicity of positions and further providing a book-holder structure for holding a book in stationary position on the flat surface.

BACKGROUND OF THE INVENTION 
This invention relates to utility desks. 
More particularly, the invention concerns a portable utility desk 
comprising a generally-rectangular, substantially-flat table member with 
leg supports and book supports adapted to a multiplicity of uses. 
In a further aspect, the invention concerns a utility desk especially 
adapted for use in at least five alternative positions, which five uses 
may be generally referred to prone reader, normal desk, back support, lap 
tray, and lounge-position reader. 
It has been a problem in the past for people who must remain in a prone 
position, whether due to illness or otherwise, to avail themselves of a 
desk or similar support for the purpose of holding a book, letter writing, 
art work, and many other purposes. Furthermore, in the case of a hospital 
patient who is bedridden and must remain in a prone position for only a 
few days or weeks, it has been economically unfeasible either to build 
something suitable for such temporary use or to attempt to purchase 
special-use equipment which will no longer be of value when the problem 
has passed. Historically, each use requiring a "desk-type" function has 
required a special purpose piece of equipment to adequately satisfy that 
use. 
Examples of areas of use for desk-type functions presently being satisfied 
with single-purpose equipment include standard desk use in which the user 
sits in a chair adjacent to the desk; the use of a tray-type flat surface 
resting on the legs of the user who is sitting up in bed; the use of an 
easel-type surface by the user sitting up in a bed or otherwise in a 
lounging position; and the use of an angled back support having sufficient 
strength and rigidity for use behind the user attempting to support and 
elevate the head and back in bed. 
Futhermore, it is seen that different structures are best adapted for such 
different uses as hereinabove mentioned. Thus there is a need for a 
utility desk which is well-adapted to a multiplicity of uses. 
In addition, when the use to which a desk-type surface is put requires a 
deviation from the horizontal, or even inversion, there is often great 
difficulty in keeping books or other similar items in place on the 
surface. Also, there is inconvenience, instability, and sometimes pain 
associated with attempting to rest the edge of a desk-type surface on the 
user's body rather than on the underlying bed or other support. 
It would be highly advantageous, therefore, to provide a portable utility 
desk which is not only adapted to a multiplicity of uses, but provides 
also for the solution of the other problems hereinbefore mentioned with 
respect to the prior art. 
SUMMARY OF THE INVENTION 
Accordingly, it is the primary object of the present invention to provide 
an improved utility desk. 
Another object of the present invention is the provision of a portable 
utility desk adapted to a multiplicity of uses, including the uses 
hereinbefore mentioned in discussing the prior art. 
Still another object is to provide a utility desk which may be handled with 
ease and is economically inexpensive. 
Yet another object of the present invention is the provision of a utility 
desk of the above type which is convenient to use and adapts to the user's 
body in a stable and easy manner. 
Even another object is to provide a utility desk which allows a book to be 
held in a slanted or inverted position. 
Yet still another object of the present invention is the provision of a 
utility desk of the above type which is efficient in its manner of 
operation, relatively inexpensive to manufacture, and having a high degree 
of durability and serviceability. 
Briefly, to accomplish the desired objectives of the present invention in 
accordance with the presently preferred embodiment thereof, there is 
provided a utility desk having a generally-rectangular, substantially-flat 
table member having a notch midway along an edge of the table member. A 
semi-circular notch is preferred. A positionally-adjustable leg member is 
detachably connected to the table member. A book support member is located 
on the table member above the notch and includes mechanical means for 
preventing a book on the table member from sliding or falling. In the 
preferred embodiment, a pair of longitudinal frame members, each having an 
L-shaped cross-section, are positioned in opposed relationship on either 
side of the table member, the opposed edges of the table member abutting 
the internal angle of the frame members. A pair of transverse book-support 
bars are located adjacent the table member and between the frame members, 
above the notch, and the ends of the book-support bars are detachably 
connected to the frame members. A pair of elastic bands is located around 
the book-support bars and stretched therebetween for the purpose of 
holding the pages of a book open. This construction permits the table 
member to be reversed so as to allow the legs to extend in either the same 
direction or opposed to the side of the table member containing the 
book-support bars.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Turning now to the drawings, in which the reference numerals indicate 
corresponding elements throughout the several views, FIGS. 1, 2, 3 and 4 
illustrate the construction of the presently preferred utility desk. Table 
member 10 (which is rectangular and flat) is positioned between first 
frame member 11 and second frame member 12 with opposed edges of table 
member 10 abutting the internal angle of the L-shaped cross-section of 
frame members 11 and 12. Leg members 14 are detachably connected to table 
member 10 by leg support connections 15, preferably friction clamps, as 
illustrated, of a type well-known in the art. A substantially 
semi-circular notch 16, as shown, is situated midway along an edge of 
table member 10. First book-support bar 17 and second book-support bar 18 
are located transverse to frame members 11 and 12, adjacent to table 
member 10 above notch 16 and between frame members 11 and 12. Book-support 
bars 17 and 18, at the ends thereof, are mechanically detachably connected 
to frame members 11 and 12. Elastic bands 19, as shown, are located around 
book-support bars 17 and 18 and stretched therebetween. Slots 20 are 
longitudinally located in frame members 11 and 12 for the purpose of 
securing book-support bars 17 and 18 to frame members 11 and 12. This slot 
construction permits the user to positionally adjust the location of the 
book supports as desired. Securing screws 21 extend from the ends of 
book-support bars 17 and 18 and pass through slots 20. Connectors 13, in a 
well-known manner, screw onto securing screws 21 to firmly, but 
detachably, connect the book-support bars 17 and 18 to frame members 11 
and 12. 
With particular reference to FIG. 1, showing the use of the utility desk of 
the present invention as a standard desk, table member 10 is located 
between frame members 11 and 12, as shown, so that the bottom side of 
table member 10 has attached thereto the leg-support connections 15. The 
utility desk of the present invention is easily assembled in this 
configuration by putting the various parts together as shown and applying 
and tightening the connectors 13. Leg members 14 are then snapped into 
place on leg-support connections 15 to provide the final structure. As 
well illustrated in FIG. 5, notch 16 allows the user full access to the 
desk, the table member fitting around the body of the user, and it is seen 
that the table member 10 may be, for comfort and convenience, easily used 
as an armrest. 
With particular reference to FIG. 2, the utility desk of the present 
invention is specifically illustrated for the use shown by the user of 
FIG. 6. Compared to the use of FIG. 1, table member 10 is first inverted, 
and then the assembly, including table member 10 and frame members 11 and 
12, is again inverted. Thus, leg-support connections 15, as illustrated, 
are located on the other side of table member 10 from the book support 
bars 17 and 18. The book-support member of the present invention, 
including book-support bars 17 and 18 and elastic bands 19, is assembled 
so that such members are located on the upper side of table member 10. The 
assembly illustrated by FIG. 2, as is seen, may be used as a sitting or 
lounging reader, for example, as clearly shown in FIG. 6. FIG. 4 
illustrates even more clearly this discussed use and further illustrates a 
book 30 in place between book-support bars 17 and 18 with the pages of 
book 30 being held at the desired position by elastic bands 19, preferably 
rubber bands. It is seen that notch 16 will comfortably fit around the 
user for the ease of the user in using the utility desk of the present 
invention in this manner. 
For maximum benefit and ease of use, it is highly preferred that the radius 
of the preferred semi-circular notch of the present invention be more than 
6 inches and less than 10 inches. These dimensions provide optimal benefit 
and comfort to an average user. 
FIG. 3 further assists in illustrating the method of assembly and 
disassembly of the various parts of the utility desk of the present 
invention for its multiplicity of uses, specifically showing, in an 
exploded view, the assembly of the table member 10, frame members 11 and 
12, book-support bars 17 and 18 including securing screws 21, connectors 
13, and even the detachable connection of leg members 14 to leg-support 
connections 15, which are attached to table member 10. 
In the use of the utility desk of the present invention as a back support, 
as shown in FIG. 8, the book-support member need not be assembled as the 
table member 10 and leg members 14 suffice to provide the desired 
backrest. 
As is clearly shown from FIG. 7, the leg members 14 are not necessary for 
the use of the present invention as a lap tray, and the book-support 
member parts will most often not be desired for such use. 
For the use of the utility desk of the present invention as a prone reader, 
which use is clearly illustrated by FIG. 9 hereof, the book-support member 
is assembled on the same side of table member 10 which includes 
leg-support connections 15. Thus, leg members 14 support the utility desk 
of the present invention in position, preferably one leg member 14 around 
either side of the user, and the utility desk is stabilized by the 
location of notch 16 around the body of the user. It is preferred that leg 
members 14 have tips of non-slip material, such as rubber, for more 
stability. As has been described, the use of elastic bands 19 for a user 
reading a book in this position will be most necessary, in combination 
with the support of book-support bars 17 and 18, in keeping a book 30 from 
slipping or falling or its pages from moving. It is particularly pointed 
out that the elastic bands 19 allow the user to turn pages, placing pages 
under the elastic bands 19 as desired. 
It is seen that the utility desk of the present invention may be utilized 
in a multiplicity of positions by assembling the parts thereof as desired 
for each use and using the same as shown herein. Even as inexperienced 
user may assemble and disassemble the utility desk of the present 
invention with ease and may transport the utility desk of the present 
invention in a highly portable manner. It is now further seen that the 
efficient and compact utility desk of the present invention is simple in 
construction and design and yet easily adaptable to its mentioned uses. 
Various changes in the device herein shown for the purpose of illustration 
will readily occur to persons skilled in the art. Such modifications and 
variations, while not specifically denoted in the foregoing detailed 
description of the preferred embodiment, do not deviate from the teachings 
of the present invention and are intended to be included in the spirit and 
scope thereof, and the scope of the present invention is intended to be 
limited only by a fair interpretation of the following claims.
