Description
BACKGROUND OF THE INVENTION
This invention relates to an elevated traction pillow which
supports the upper body of an individual in a raised or
semireclining position. The novel design of this pillow causes a
stretching and relaxing of the neck muscles to provide greater
comfort and rest to the user thereof.
It is often desirable to support the body in a raised or
semireclining position. Patients suffering from cardiac conditions,
emphysema, and respiratory difficulties commonly sleep and rest in
a raised or semireclining position. This same position is desirable
when reading in bed or watching television.
Commonly, the support used to maintain this position is a number of
ordinary pillows. The pillows are generally placed under the
shoulders and head so as to curve the spine. This position is
difficult to maintain, with any degree of comfort, for long time
intervals. Additionally, the body cannot rest naturally in this
position and various physical ailments may be caused thereby.
Various types of pillows have been designed to elevate the head and
the upper body. None of these pillows, however, support the upper
body and the head, when in the semireclining, supine position, in
such a manner as to apply traction to the neck muscles. By applying
traction to these muscles the entire body is relaxed and
benefitted.
A pillow adapted to support the head and neck of an individual in
the supine position is disclosed in my copending application
entitled Pillow Construction, filed July 25, 1968, Ser. No.
747,722, now U.S. Pat. No. 3,421,310.
SUMMARY OF THE INVENTION
This invention relates to an elevated traction pillow for
supporting the back, neck and head of an individual in a
semireclining, supine position. The pillow comprises a firm support
member, in side view, of substantially triangular configuration,
and a head receiving member secured in the firm support member
proximate the apex of the triangular configuration and being in
contacting engagement with the firm support member. The
head-receiving member offers only negligible resistance when
receiving the head of an individual.
It is an object of this invention to provide an elevated, traction
pillow of novel design.
Another object is to provide an elevated traction pillow wherein
the back is supported on an inclined plane by a firm support member
and the head is supported by a head-receiving member which offers
only negligible resistance when receiving the head of an
individual.
A further object is to provide an elevated, traction pillow wherein
the neck muscles are selectively stretched.
Yet another object is to provide an elevated, traction pillow as
described above having formed on the firm support member adjacent
the head-receiving portion, a raised portion adapted to receive and
support the neck of an individual.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, the elevated traction pillow of this
invention is indicated generally at 11 in FIGS. 1-5. The pillow 11
comprises a firm support member 12 (FIGS. 1-5) of generally
triangular configuration, a head-receiving member 13 (FIGS. 1-5),
and a raised portion 14 (FIGS. 1-4) for supporting the neck of an
individual reclining thereon in the supine position. In FIGS. 1 and
4, the component parts of this pillow 11 are covered with an outer
ticking 16.
The firm support member 12 (FIGS. 1, 3-5) is, in side view, of
substantially triangular or wedge-shaped configuration, preferably,
of right triangular configuration. The user of this pillow 11
reclines on the hypotenuse 17 of the right triangle (FIG. 4).
Proximate the apex 18 of the right triangle (FIG. 5) or at the apex
18 (FIGS. 1-4) a depression 19 (FIGS. 3-5) is formed in the firm
support member 12. The head-receiving member 13 is received in this
depression 19.
The depression 19 (FIGS. 3 and 5) preferably extends from one side
21 of the pillow 11 to the other side 22 (FIGS. 1 and 2). The
longitudinal edges 23 and 24 of the depression 19 are preferably
parallel and substantially vertically disposed. The depth of the
depression 19 is not critical, however, it must be deep enough to
allow the head 26 of an individual 27 to sink downwardly therein as
illustrated in FIG. 4.
The firm support member 12 may, in a preferred embodiment (FIG. 5),
encompass the head-receiving member 13 on all sides except that
side forming a portion of the hypotenuse 17. By surrounding the
head-receiving member 13 on all sides, the pillow 11 retains its
shape better and stress and strain on the joints between the firm
support member 12 and the head-receiving member 13 are reduced.
The firm support member 12 should extend from proximate the sacrum
28 to proximate the top of the head 26, generally about 26 inches.
In width, the firm support member 13 is generally about 26 inches.
The depth can vary from about 6 inches to about 26 inches although
a slope of 45.degree. is quite unusual and is generally not
utilized herein.
The firm support member 12 can be manufactured from a number of
different materials. One of the preferred materials is a urethane
foam having a compression density of from about 20 pounds to about
40 pounds. Material of this compression density is adequate to
properly support the back and shoulders of an individual utilizing
this pillow. The compression density of this material is calculated
by the standard R.M.A. test.
Preferably, the urethane foam is cut rather than molded. A skin
forms on molded urethane foams and prevents them from "breathing".
Cut urethane foams, however, are porous and breathe exceptionally
well and are generally very comfortable to recline thereon.
The head-receiving member 13 (FIGS. 1-3 and 5) is of the same
general configuration as the depression 19 formed in the firm
support member 12. The top 29 of the head-receiving member 13 forms
a portion of the hypotenuse 17 of the triangular configuration. The
head-receiving member 13 is secured in the depression 19 in
contacting engagement with the firm support member 12 by any
suitable means. One of the least expensive methods of securement is
bonding these two components together with glue.
The head-receiving member 13 can also be comprised of a number of
materials if those materials offer negligible resistance when
receiving the head 26 of an individual 27. Polyester fibers having
a compression density of less than about 6 pounds are suitable for
use herein. Other materials having approximately this same
compression density can also be used herein.
A raised portion 14 (FIGS. 1-4) is formed on the firm support
member 12 adjacent the head-receiving member 13 for receiving and
supporting the neck 31 of an individual reclining on the pillow 11.
The raised portion 14 generally extends from one side 21 to the
other side 22 of the pillow 11 and is raised above the hypotenuse
17 of the triangular configuration. The raised portion 14 is
contoured to properly fit the neck 31 (FIG. 4) between the
shoulders 32 and the head 26. The raised portion 14 keeps the neck
31 in proper alignment with the normal curvature of the spine when
the user 27 thereof is in a semireclining, supine position (FIG.
4).
The raised portion 14 has another use (FIG. 3). When watching
television or reading, the user 27 can utilize the raised portion
14 as a head rest as illustrated in FIG. 3.
The raised portion 14 can be manufactured from many materials. One
that has been found useful herein is urethane foam having a
compression density of from 8 pounds to about 16 pounds. The raised
portion 14 is secured to the firm support member 12 by any
convenient means, generally by glueing.
The entire pillow 11 is preferably covered with a ticking 16. If
the pillow 11 is used in the home, corduroy or similar heavy duty
cloth is preferred for the ticking 16. When the pillow 11 is used
in hospitals and nursing homes, the ticking 16 is preferably white
cotton which can readily be laundered.
The abrupt transition from the firm support member 12 and the
raised portion 14 to the relatively soft head-receiving member 13
provides this pillow with the unique feature of stretching the neck
muscles and permitting them to relax, thereby leading to a more
restful sleep and reduced likelihood of neck and shoulder
spasms.
Although a preferred embodiment of this invention has been
described and disclosed hereinbefore, it is to be remembered that
various modifications can be made thereto without departing from
the true spirit and scope of the invention as defined in the
appended claims.
