BACKGROUND OF THE INVENTION
This invention relates generally to pillows and more specifically to
speaker pillows which are adapted to support the head of the person lying
thereon.
DISCUSSION OF THE PRIOR ART
When a person is resting, it is desirable to support his head in a natural
state with as little pressure applied to the head as possible. Pillows are
commonly used for this purpose. In pursuit of that objection pillows have
been adapted not only to elevate the head of the user but also to provide
a soft surface which increases the area of contact and therefore decreases
the pressure on the head and neck of the user.
Particularly when one is attempting to rest in a noisy environment, such as
on an airplane, it is desirable to attenuate the noise which of course is
counterproductive to sleep. Earplugs are commonly used for this purpose.
In order to be effective, such earplugs must be lodged with considerable
force within the ear canal. This force, particularly when applied over a
long period of time can be sufficiently objectionable that it also is
counterproductive to sleep.
It may also be desirable while resting to produce sound at a very low level
to sooth the user or perhaps aid in self-hypnosis or subliminal
suggestion. Audio headsets having a speaker for each ear are sometimes
used in conjunction with audio tapes or cassette disks for this purpose.
Where these headsets are used in a noisy environment, the sound from the
headsets must be elevated in order to be audible over the background
noise. When so elevated, the audio sound may also be audible to others who
often find the sound objectionable.
SUMMARY OF THE INVENTION
An acoustical pillow of the present invention overcomes these shortcomings
of the prior art. It includes an elongate pillow having a core which
extends along an axis through a central section and into opposing end
sections. In use, the central section elevates and softly supports the
head of the user thus functioning as an orthopedic cervical pillow which
allows the spine to rest correctly and comfortably.
The end sections are bent from the central section and extend to snugly
engage the sides of the head thereby supporting the head in an upright
position which is squared with the shoulders of the user. With the end
sections of the pillow configured to snugly engage the ears of the user,
these sections attenuate any environmental noise which may otherwise
interfere with sleep. A pair of speakers can also be provided in the end
sections of the pillow where they are positioned to be closely spaced to
the ears of the user.
A preferred embodiment includes a spring which extends through the sections
of the pillow and biases the end sections into the snug fit relationship
with the ears of the user. In this embodiment the spring performs several
functions. First, it aids in supporting the head of the user in a squared
relationship with the shoulders. Second, it facilitates isolation of the
ears of the user from environmental noise. Third, it aids in maintaining
the speakers in a closely spaced relationship to the ears of the user
thereby facilitating communication of the audio sound. With the end
sections of the pillow attenuating environmental sound and the speakers
placed in close proximity to the user's ears, the audible sound from the
speakers can be maintained at a lower level which does not interfere with
the privacy of others.
In a preferred embodiment the pillow includes a tote bag which can be
stored within a pillow case during normal use, but which can be everted
from the pillow case to enclose the pillow. A strap associated with the
tote bag facilitates portability of the acoustical pillow.
In one aspect of the invention, the speaker-pillow is adapted to support
the head of a user and includes a core having an axis and a longitudinal
surface extending between opposing end sections. The axis is bent so that
the end sections extend in a common direction. A pair of speakers are
disposed in the end sections and adapted to face each other in close
proximity to the user's ears. A spring is disposed to extend into the end
sections for biasing these sections into a snug fit relationship with the
ears of the user. A pillow cover surrounds the pillow and an electrical
cord extends from each of the speakers through the pillow cover for
connection to an audio source.
In another aspect of the invention, the pillow does not include speakers
but the spring is included for biasing the end sections against the ears
of the user to attenuate environmental sound.
In a further aspect of the invention, the end sections in snug engagement
with the ears of the user provide means for facilitating introduction of
audio sound from the speakers while inhibiting communication of
undesirable noise from the environment to the ears of the user.
These and other features and advantages of the invention will become more
apparent with a description of the best mode of the invention and
reference to the associated drawings.

DESCRIPTION OF PREFERRED EMBODIMENTS
An acoustical pillow is illustrated in FIG. 1 and designated generally by
the reference numeral 10. The pillow 10 is shown in use by a person 12
having a head 14 and a pair of ears 16. The pillow 10 includes a center
section 18 and a pair of end sections 21 and 23. These end sections 21 and
23 are disposed on opposite sides of the central section 18 and are bent
therefrom in a common direction so that the pillow 10 has a generally
U-shaped configuration.
With the pillow 10 formed in this manner, it is particularly adapted to
support the head 14 in a relaxed elevated position so that the spine of
the person 12 is correctly positioned to facilitate rest or sleep. With
the head 14 resting on the center section 18 of the pillow, the end
sections 21 and 23 engage the sides of the head 14 thereby maintaining it
in a comfortable position squared with the shoulders of the user.
These end sections 21 and 23 snugly engage the ears 16 to attenuate any
environmental sounds which might otherwise interfere with rest. Thus the
pillow 10 facilitates relaxation by providing a soft supporting surface,
by positioning the head 14 and spine with correctness and ease, but also
by acoustically quieting the sleep environment. A spring 28 may also be
provided to extend through the center section 18 and bias the end sections
21 and 23 into a snug fit against the ears 16 of the person 12. The pillow
10 can be provided with a pair of speakers 25 and 27, best shown in FIG.
3, which can be connected through a conductor 30 to an audio source such
as a cassette or compact disc player 32. The pillow 10 may also include a
pillow case 34 which is closed in the illustrated embodiment by a pair of
draw strings 36.
The construction of the pillow 10 will be more apparent with reference to
the exploded view of FIG. 2. With more specific reference to FIG. 2a, this
embodiment of the pillow 10 is illustrated to include a core 41 which is
cut in the U-shaped configuration from a soft compliant material such as
foam rubber. In a preferred method of manufacture, the core 41 is cut from
a block of foam rubber which is four inches thick, twelve inches long and
eight inches wide. The center section 18 of the core 41 extends generally
along the length of the foam block while the end sections 21 and 23 extend
generally along the width of the foam block.
After cutting, as illustrated in FIG. 2a, the core 41 in this embodiment
has a top surface 43, a bottom surface 45, a side surface 47, and two end
surfaces 50 and 52. Each of these surfaces 43-52 comprise outer surfaces
in that they face away from the interior of the U-shaped core 41. An inner
surface 54 is the only surface which faces inwardly of this U-shaped
configuration. With this shape, the core 41 can be described as having an
elongate configuration extending along an axis 61 where the end sections
21 and 23 are bent along the axis 61 in a common direction.
In a preferred embodiment, a cross-section taken perpendicular to the axis
61 may have a uniform rectangular configuration, a separation of about six
inches between opposing ends of the inner surface 54 provides each of the
end sections 50, 52 with a rectangular configuration and dimensions of
three inches by four inches in this particular embodiment. The end
surfaces 50, 52 will typically be formed in a common plane while the
surfaces 43 and 45 will be generally parallel. The inner surface 54 and
side surface 47 are curved but have similar shapes so that these surfaces
also have a generally parallel relationship in this embodiment.
It is to be understood that these relationships of the surfaces and the
specific dimensions disclosed for this particular embodiment, may vary
widely within the concept of the invention which benefits primarily from
the U-shaped configuration of the core 41.
After the core 41 has been formed, a slit 65 can be cut in the core 41 to
receive the speakers 25 and 27 previously discussed. In a preferred
embodiment, this slit extends between the axis 61 inwardly toward and
generally perpendicular to the surface 54. In this case, the slit 65 has a
generally planar configuration and is disposed intermediate between and
generally parallel to the surfaces 43 and 45. With this configuration, the
slit 65 is particularly adapted to receive the spring 28 and/or the
speakers 25, 27.
In addition to the slit 65, a slot 67 can be formed in the plane of the
slit 65 to extend entirely across one of the end sections, such as the end
section 23. Communicating with the slit 65, the slot 67 provides a channel
through which the conductor 30 can be laid to engage the speakers 25 and
27 in the slit 65 while exiting the pillow 10 through the slot 67 at the
side surface 47.
After the core 41 has been formed and the spring 28 and/or speakers 25, 27
have been positioned within the slit 21, the core 41 can be covered by a
layer of fiberfill 70 best illustrated in FIG. 2b. In a preferred
embodiment, a 24 inch by 30 inch sheet of nine ounce fiberfill is wrapped
around the center section 18 and up the side sections 21 and 23 of the
core 41. Importantly, the layer of fiberfill 70 overlaps itself in
proximity to the inner surface 54 as shown by the arrow 72 in FIG. 2b. In
this location the overlapping fiberfill 70 adds softness and compliance to
the area which supports the head 14 of the person 12.
After the core 41 has been wrapped with the fiberfill 70, this combination
can be compressed and loaded into a cover 76, best illustrated in FIG. 2c.
In a preferred embodiment, the cover 76 is sewn from one piece of a
polycotton batiste material. This piece of material can be sewn along a
seam 79 into the configuration of a tube 78 where the ends of the tube are
closed by generally circular end panels 81 and 83. A reinforced hole 85
can be formed in the tube 78 to enable the conductor 30 to exit the cover
76. The core 41 and fiberfill 70 are most easily loaded into the cover 76
by leaving an opening 87 in the seam 79 at the center section 18. This
opening 87 can be hand sewn to complete the cover 76.
As a final step in the manufacturing process, the core 41, fiberfill 70 and
cover 76 can be loaded into the pillow case 34. This pillow case 34 will
typically be configured not only for its structural features but also its
aesthetic appearance. Thus in a preferred embodiment, the pillow case 34
is formed in the configuration of a tube 90 by joining two pieces of
colorful material along an inner seam 92 and an outer seam 94. These two
seams 92 and 94 in a preferred embodiment lie in a common plane with the
axis 61 and the slit 65 associated with the core 41.
The tube 90 of the pillow case 34 has a generally constant circumferential
dimension between its ends 96 and 98 which are preferably left open to
facilitate loading the core 41 into the case 34. These ends 96 and 98 are
circumferentially hemmed and the drawstrings 36 are laced through the hems
in a conventional manner. By pulling the drawstrings 36, the ends 96 and
98 of the case 34 can be gathered around the end sections 21 and 23 of the
core 41.
A opening 101 can be left in the outer seam 94 of the pillow case 34 to
provide an exit for the conductor 30. It may also be desirable to provide
one or more pockets 103 on the outside of the case 34 to accommodate
storage of the conductor 30 and perhaps the audio player 32 when the
pillow 10 is not in use. In a preferred embodiment, the pocket 103 is
formed over the exit hole 101 so that the conductor 30 cannot be seen when
it is stored in the pocket 103.
In a further embodiment of the invention, a tote bag 110 is provided to
receive the pillow 10. In a preferred embodiment, the tote bag 110 is
formed from two pieces of material which are partially joined at their
perimeters along a seam 112. A handle in the form of a shoulder strap 114
can be attached to the bag 110 along the seam 112. A storage pocket 116
may also be provided on the inside of the bag 110.
In a preferred embodiment, the pillow case 34 is provided with an opening
121, best shown in FIG. 8, along the outer seam 94 in the vicinity of the
center section 18 This opening 121 which is defined by edges 122, is
provided with a zipper which alternatively closes or opens the opening
121.
The tote bag 110 is also provided with an opening 130 in the seam 112. In a
preferred embodiment, the tote bag 110 is permanently attached to the
pillow case 34 at the respective openings 130 and 121. Thus the edges 132
of the opening 130 are sewn to the edges 122 of the opening 121.
Importantly, the edges 132 are sewn to the edges 122 interiorly of the
pillow case 34 and the zipper 123. With this configuration the tote bag
110 can be stuffed through the opened zipper 123 and the opening 121 to
reside within the pillow case 34 in a stored position, when the pillow 10
is in use. When the pillow is no longer being used, the zipper 123 can be
opened to permit the tote bag 110 to be withdrawn from the pillow case 34.
From this position, illustrated in FIG. 8, the bag 110 can be turned
inside out or everted over the pillow 10 as illustrated in FIG. 9. In this
tote position, the zipper 123 is hidden and the opening 121 remains open.
In the foregoing description, the spring 28 has been mentioned only briefly
but may be of particular interest to several embodiments of the invention.
This spring 28 which will typically be a leaf spring, may be formed from
plastic, metal or any other material providing the desired spring
characteristic. The spring will be formed in the U-shaped configuration
with its ends biased toward a closed relationship rather than an open
relationship. When disposed within the core 41, these characteristics of
the spring 28 will bias the end sections 21 and 23 of the core toward each
other to provide the desired snug engaging fit with the ears 16 of the
person 12. In a particular embodiment, it may be desirable that the slit
65 not extend in the direction of this spring bias. In such a case, a slit
could be provided to extend toward the axis from either the top surface
43, the bottom surface 45 or the side surface 47. The slit 65 discussed
with reference to FIG. 2a seems to be best suited for an embodiment which
includes both the spring 28 and the speakers 25 and 27. In such an
embodiment, the speakers 25 and 27 may be mounted on the ends of the
spring 28 to form a subassembly which can be loaded directly into the slit
65.
These are just a few of the many variations on the foregoing concept which
are all deemed to be within the scope of the invention. Other variations
in the types of material, the location of seams, and the types of closure
mechanisms will be readily apparent to those skilled in the art.
Given these wide variations, which are all within the scope of this
concept, one is cautioned not to restrict the invention to the embodiments
which have been specifically disclosed and illustrated, but rather
encouraged to determine the scope of the invention only with reference to
the following claims.
