| Inventor(s) | Sanders; Janice L. (Arlington, TX) |
| Abstract | An orthopedic pillow having separately adjustable neckroll and head-support
sections. The neckroll section has a foam rubber pad rolled into a spiral
roll and housed within a cylindrical case. The case can be opened to allow
the pad to be removed and trimmed. The diameter of the neckroll can thus
be adjusted to correspond to the contour of the user's neck. The
head-support section has an outer section and an inner section. The
thickness of the outer portion may be adjusted by adding or removing
filler material. The thickness of the inner portion may be adjusted by
adding or removing inlays in a stacked arrangement. |

BACKGROUND OF THE INVENTION
This invention relates generally to orthopedic support pillows. In
particular, the invention relates to adjustable pillows for supporting a
person's head and neck during sleep.
It is known in the art to provide pillows of varying contour to provide
adequate support for a person's head and neck during sleep. For example,
U.S. Pat. No. 4,494,261, issued to Morrow on Jan. 22, 1985, and U.S. Pat.
No. 3,667,074, issued to Emery on June 6, 1972, disclose such pillows.
Yet, a need exists for conveniently accomodating the varying head and neck
contours of different individuals.
Accordingly, it is a principle object of the present invention to provide
an inexpensive and readily adjustable pillow for orthopedic head and neck
support.
SUMMARY OF THE INVENTION
The pillow of the invention is adjustable to the size of the user's neck
and head. The pillow has a neckroll section for supporting the user's
neck. The neckroll section is a pad rolled into a spiral configuration and
inserted into a cylindrical case. If necessary, the pad can be removed
from the case and trimmed to provide a selected diameter when returned to
the case.
The pillow also has a head-support section, attached to the neckroll
section, for supporting the user's head. An inner portion of the
head-support section is adjacent to the neckroll section and is surrounded
on the other three sides by an outer portion of the head-support section.
The outer portion has an outer cover and a quantity of filler material
within the cover. The thickness of the outer portion can be adjusted by
adding or removing filler material.
The thickness of the inner portion of the head-support section can be
adjusted by adding or removing a plurality of relatively flat inlays. A
connector or closure, such as a loop and pile connector, is located on
each side of each inlay and on the upper surface of the inner portion.
Accordingly, a selected number of inlays can be attached to the inner
portion of the head-support section, depending upon the thickness required
to properly support the user's head.
Additional features and advantages of the invention will be readily
understood from the following detailed description read in connection with
the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As illustrated in FIGS. 1-3, a preferred embodiment of a pillow 11 in
accordance with the present invention has two major sections, which are a
neckroll section 13 and a head-support section 15. The head-support
section 15 is generally rectangular, and the neckroll section 13 is sewn
to one of the longer edges of the head-support section 15.
The neckroll section 13 is designed to support the user's neck, and has a
foam rubber pad 17 rolled into a spiral configuration. The pad 17 is
housed within a cylindrical case 19 having open ends 21 and 23. If desired
for aesthetic reasons, the ends 21 and 23 of the case 19 may be closed.
The case 19 is rectangular piece of cloth sewn to the head-support section
15. The opposite edges of the cloth piece 25 are held together by a
plurality of loop and pile closures 29, preferably of the type sold under
the trademark VELCRO. The closures 29 can be opened to allow easy removal
of the pad 17 from the case 19.
The foam rubber pad 17 is approximately the same width as the case 19, but
is substantially longer in its extended condition prior to being rolled
into a spiral. If a smaller neckroll 13 is desired, the pad 17 can be
removed from the case 19 and trimmed to provide a selected diameter when
returned to the case 19. The loop and pile closures 29 allow the two sides
of the case 19 to be wrapped firmly in opposite directions around the
trimmed pad 17. The case 19 can thus be adjusted to fit the diameter of
the rolled pad 17.
The head-support section 15 has an outer portion 31 and an inner portion
33. The outer portion 31 of the head-support section 15 has an outer cover
35, filled with a quantity of filler material 36, seen in FIG. 1A. The
thickness of the outer portion 31 can be adjusted by opening a zipper 38,
shown in FIG. 3, and adding or removing filler material 36 through the
opening. The filler material 36 may be any conventional material used in
pillows such as polyester fiber. The outer portion 31 has numerous pleats
37 to allow the outer portion 31 to expand.
The inner portion 33 of the head-support section 15 is adjacent to the
neckroll section 13 and is surrounded on the other three sides by the
outer portion 31. The inner portion 33 has little or no filler material
and is thus much thinner than the outer portion 31 as seen in FIG. 1A.
The thickness of the inner portion 33 can be adjusted by adding or removing
a plurality of adjustment elements, such as relatively flat inlays 39. As
shown in FIG. 4, each inlay 39 has complimentary parts 41 and 42 of a loop
and pile connector located on each side of the inlay 39. Another loop and
pile connector 43 is located in the middle of the inner portion 33 of the
head-support section 15, as shown in FIG. 2.
The first inlay 39 is attached to the connector 43 in the inner portion 33
of the head-support section 15. The connectors 41 and 42 on the inlays 39
allow additional inlays 39 to be selectively added to or removed from a
stack of inlays 39 on the inner portion 33.
Rather than placing the inlays 39 upon the surface of the inner portion 33,
the inlays 39 could alternatively be placed within a pocket (not shown) at
the inner portion. Alternatively, filler material could be placed within
such a pocket. Also, the adjustment elements could be inflatable members,
rather than removable inlays 39.
Adjustment of the head-support and neckroll sections 13 and 15 to
accomodate individuals having different head and neck contours can readily
be accomplished with the pillow 11 of the present invention. A person
using the pillow 11 of the invention lies on the pillow 11 with his or her
neck on the neckroll section 13 and with his or her head on the
head-support section 15. The neckroll section 13 is adjusted by opening
the closures 29 on the case 19, removing and trimming the pad 17, and
returning the pad 17 rolled in a spiral configuration to the case 19. The
closures 29 allow the case 19 to be wrapped firmly around the pad 17.
The head-support section 15 of the pillow 11 can be adjusted in two ways.
The outer portion 31 of the head-support section 15 is adjusted by adding
or removing filler material 36. The thickness of the inner portion 33 is
adjusted by adding or removing inlays 39.
The pillow 11 of the invention has several advantages over the prior art.
The thickness of the inner portion 33 of the head-support section 15 can
be easily and quickly adjusted by adding or removing a selected number of
inlays 39. The thickness of the outer portion 31 of the head-support
section 15 can be readily adjusted in the above-described manner to
provide peripheral support at the back of the head. The neckroll section
13 can be easily adjusted to maintain cervical support and minimal stress
in cooperation with the separately adjustable portions of the head-support
section 15. The pillow 11 of the invention thus provides optimum
orthopedic support for the upper spine and head of the user.
The invention has been illustrated and described in only one of its
preferred embodiments. It will be understood, however, that the invention
is not so limited, but that various changes and modifications may be
resorted to without departing from the spirit and scope of the invention
as described by the appended claims.
