Claims
What is claimed as new is as follows:
1. A noise absorbing pillow construction comprising a thick
panel-like body having upper and lower surfaces, said body being
constructed of soft, shape-retentive and resilient cellular
material, the upper and lower surfaces of said body including
longitudinally and transversely spaced outwardly opening blind
recesses formed therein of substantially the same width, said
recesses each having a minimum width of more than one inch and a
maximum width of less than three inches, said recesses being
substantially two inches in width and disposed on centers spaced
apart both transversely and longitudinally of said body
substantially three inches, said recesses extending approximately
one third through the thickness of the body and the recesses
opening outwardly of the upper surface of the body being vertically
registered with the recesses opening outwardly of the lower surface
of the body, and a cloth cover loosely enclosing said body.
Description
BACKGROUND OF THE INVENTION
Occasionally, when persons are attempting to go to sleep, they
become aware of the pulsating sound of their heart beat and in some
instances the awareness of one's heart beat results in
insomnia.
In addition, some persons ears are sensitive to pressures thereon
while their heads are lying on pillows and other persons become
aware of excessive warmth of the side of their heads resting on
pillows.
BRIEF SUMMARY OF THE INVENTION
The pillow of the instant invention may be rectangular in plan
shape, although other shapes may also be utilized, and is
constructed of soft, shape-retentive and resilient cellular
material. The upper and lower surfaces of the pillow body are
provided with vertically registered upwardly and downwardly opening
recesses of approximately two inches in diameter spaced over the
upper and lower surfaces of the pillow body. The soft construction
of the pillow in conjunction with the specifically shaped and
arranged recesses function to dampen the pulsating sound of one's
heart beat while his or her head is lying on the pillow and
registry of a sleeper's ear with one of the upwardly opening
recesses will relieve substantially all pressures from the ear.
Further, the registry of one's ear with one of the upwardly opening
recesses in the pillow body and various spaced adjacent portions of
one's head with adjacent recesses in the upper surface of the
pillow body functions to prevent a buildup of heat at the side of
that person's head resting upon the pillow.
The main object of this invention is to provide a pillow which will
effectively dampen the sound of a pulsating heart beat while the
user of the pillow has his or her head resting thereon.
Another object of this invention, in accordance with the
immediately preceeding object, is to provide a pillow which may
function to effectively reduce the pressure offered by the pillow
on the ear of the user of the pillow resting thereon.
Still another object of this invention is to provide a pillow which
will more readily dissipate heat from the side of the user's head
resting upon the pillow.
A final object of this invention to be specifically enumerated
herein is to provide a pillow in accordance with the preceding
objects and which will conform to conventional forms of
manufacture, be of simple construction and easy to use so as to
provide a device that will be economically feasible, long lasting
and relatively trouble-free in operation.
These together with other objects and advantages which will become
subsequently apparent reside in the details of construction and
operation as more fully hereinafter described and claimed,
reference being had to the accompanying drawings forming a part
hereof, wherein like numerals refer to like parts throughout.
FIG. 1 is a perspective view of the pillow body of the instant
invention;
FIG. 2 is a side elevational view of the pillow body illustrated on
somewhat of an enlarged scale; and
FIG. 3 is an enlarged fragmentary transverse vertical sectional
view taken substantially upon the plane indicated by the section
line 3--3 of FIG. 1 and with a flexible cloth covering secured over
the pillow body preparatory to the pillow body and cloth covering
being inserted in a pillow case.
DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now more specifically to the drawings, the numeral 10
generally designates a pillow body constructed in accordance with
the present invention. The body 10 comprises a generally
rectangular panel which may be approximately 22 inches in length
and 14 inches in width. The body 10 is approximately four inches in
thickness and includes upper and lower surfaces 12 and 14,
respectively.
The upper portion of the body 10 has four transversely spaced
longitudinal rows of longitudinally spaced upwardly opening
recesses 16 formed therein. The recesses 16 are approximately one
and one-half inches in depth and are cylindrical having a diameter
of two inches. In addition, the under or lower surface 14 of the
body 10 includes recesses 18 corresponding to and in vertical
registry with the recesses 16. Inasmuch as the recesses 16 and 18
are one and one-half inches in vertical extent, they extend
slightly more than one third of the distance through the vertical
thickness of the body 10.
The body 10 is constructed of soft, shape-retentive and resilient
cellular material such as foam rubber and includes beveled upper
and lower peripheral edges 20 and 22. Still further, the body 10 is
enclosed within a somewhat loosely fitting cloth cover 24 and the
covered body 10 may be readily placed within any conventional
pillow slip or case.
In operation, a person using the pillow places his or her head
thereon with the lower ear in registry with one of the recesses
opening upwardly through the upper surface of the body 10. In this
manner, the pulsating sound of that person's heart beat is dampened
and is not as readily transmitted to the ear. Also, the pressure of
the person's head pressing down on the body 10 is substantially
reduced in the area of that person's ear resting upon the body
because of the ear being registered with one of the upwardly
opening recesses and the underside of the person's head resting
upon the body has less tendency to experience a buildup of body
heat. Accordingly, the body 10 may be utilized in the construction
of a pillow which greatly reduces at least three causes of
insomnia.
While some persons do not experience insomnia and are substantially
always able to quickly fall asleep, other persons are more
susceptible to insomnia and the pillow of the instant invention is
constructed in a manner whereby at least three major causes of
insomnia are reduced.
The foregoing is considered as illustrative only of the principles
of the invention. Further, since numerous modifications and changes
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
ahown and described, and accordingly all suitable modifications and
equivalents may be resorted to, falling within the scope of the
invention.
