FIELD OF THE INVENTION
[0001] The present invention is to provide a head pillow, in particular to a head relaxing
pillow made of an elastic material for supporting the neck and the head of a user
who lies face up and is in a configuration for allowing the gaps in the user's skull
to open slightly to lower the pressure of the cerebrospinal fluid in the skull, and
thereby to enhance circulation of the cerebrospinal fluid.
BACKGROUND OF THE INVENTION
[0002] Recently, with the vigorous development of information dissemination and the rapid
changes in modern society, the pace of lives has been increasing, and the same can
be said of work stress. If one fails to relax his body and mind properly, physical
and mental diseases tend to follow. Many people resort to massage or tui-na for bodily
and mental relaxation, but both massage and tui-na are associated with the acupoints
and joints of the body and therefore must be practiced by experienced professionals.
While the market is now supplied with a variety of health equipment (e.g., massage
chairs) designed to relax (e.g., massage) a user's body in his own home, the soaring
prices make such equipment inaccessible to all.
[0003] In fact, not all practices of massage and tui-na require profound medical knowledge.
For example, craniosacral therapy (CST), which was developed through years of research
and clinical tests by the academic community, involves pressing a patient's head with
fingers, with a gentle pressure less than 5 gram per cm
2 or 5 gram per inch
2, to enhance the balance of body movements and to promote the flow of bodily fluids.
As the use of craniosacral therapy does not require sophisticated medical knowledge,
it can be learned by the general public. Besides, the gentle press of craniosacral
therapy, generally not heavier than the weight of a coin (5 grams), leaves no undesirable
consequences even if applied slightly off the target positions.
[0004] The idea of craniosacral therapy began in the early 20
th century, when Dr. William Sutherland, a US orthopedist, found that the bones making
up the human skull are slightly movable relative to one another rather than "totally
immovable" as traditionally held in the medical world. Sutherland spent over 20 years
studying and recording the reactions of force applied to different parts of each skull
bone, and the result was the development of a skull examination and therapy system.
Then, in 1970s, Dr. John E. Upledger, a neurosurgeon, who frequently participated
in brain surgeries, found an interesting phenomenon that the human head and dura mater
tend to move with the pulsing of the cerebrospinal fluid. He also found that the slight
pulses can be felt by touching certain parts of the body, and that by applying a very
gentle pressure (about 5 gram per cm
2 or 5 gram per inch
2) with the touching hands, the pressure of the cerebrospinal fluid can be adjusted
for better health.
[0005] After decades of research, Upledger proposed the aforesaid craniosacral therapy,
whose principles are briefly stated as follows. To begin with, the craniosacral system,
which is a rhythmic system of the human body in addition to heartbeat and breathing,
includes the meninges and the cerebrospinal fluid that protects the brain and the
spinal cord. The extent of the craniosacral system starts from such upper parts of
the body as the skull, the face, and the mouth and extends all the way downward to
the sacrum or coccyx. As the craniosacral system influences the development and operation
of the brain and the spinal cord, an unbalance or hindrance of the craniosacral system
may lead to obstacles in the sensory, motor, or neural system. Craniosacral therapy
is a therapy that assists the natural healing ability of the human body. A patient
is generally requested to lie or sit on a therapy bed while the therapist puts his
hands gently on the patient's body to "listen" to the rhythm inside. Craniosacral
therapy is a gentle, manual, and holistic approach to physical examination and treatment
and is beneficial to many body systems. Whether performed alone or in combination
with other therapies, craniosacral therapy works equally well on the human body.
[0006] Referring to FIG. 1 and FIG. 2, the human skull is composed of several bones, including
the frontal bone FB, the sphenoid bones SB, the parietal bones PB, the occipital bone
OB, and the temporal bones TB, to mention only those directly related to craniosacral
therapy. During craniosacral therapy, the therapist supports the patient's two parietal
bones PB with hands so as to relax the mastoid process TB1 of each temporal bone TB.
Then, the therapist presses the patient's occipital bone OB at positions adjacent
to the external occipital protuberance EOP and the exit occipital crest EOC (the therapist
should not press beyond the jugular processes OB1 of the occipital bone OB, i.e.,
where the occipitomastoid sutures OS are situated). At this moment, the parietal bones
PB will have moved outward to a small degree such that the gap therebetween opens
slightly. As a result, the pressure of the cerebrospinal fluid inside the skull is
reduced to enhance circulation of the cerebrospinal fluid. Craniosacral therapy helps
improve the internal environment of the human body and restore the central nervous
system to its optimal working condition. The same therapy can also provide an increased
sense of ease and comfort, strengthen the immune system, and even improve patients'
interpersonal relationships.
[0007] However, craniosacral therapy nowadays is mostly practiced by professionals (e.g.,
doctors, physical therapists, occupational therapists, chiropractors, etc.) and is
rarely known to the public. Given its low prevalence, craniosacral therapy is also
extremely expensive. In consideration of this, the inventor of the present invention
came up with the idea of applying the principles of craniosacral therapy to the design
of pillows, with a view to enabling the general public to feel the effects of craniosacral
therapy, thereby increasing the understanding and acceptance of the therapy while
promoting Dr. Upledger's painstaking research results. The issue to be addressed by
the present invention, therefore, is to design a pillow with a novel structure capable
of helping one who rests his head on the pillow to relax his head.
BRIEF SUMMARY OF THE INVENTION
[0008] It is an objective of the present invention to provide a head relaxing pillow. The
pillow is made of an elastic material and includes a supporting main body, two contact
portions, and a pressing portion. The top of the supporting main body is designed
to support the neck of a user who lies face up. The bottom of the supporting main
body is concavely provided with a recess. The supporting main body is provided with
two sunken portions which are adjacent to two corresponding ends of the supporting
main body respectively and which correspond in position to the user's temporal bones
respectively. Each contact portion has one end connected to one of the two corresponding
ends of the supporting main body. The other end (hereinafter referred to as the second
end) of each contact portion corresponds in configuration to the corresponding one
of the user's parietal bones. The pressing portion extends from one side of the supporting
main body and is located between the contact portions. When the user is lying, face
up, such that his neck and head are resting on the supporting main body and the contact
portions respectively, the user's temporal bones correspond in position to the sunken
portions respectively. Meanwhile, the supporting main body is deformed (i.e., sags)
toward the recess due to the weight of the user's neck, thereby bending the second
ends of the contact portions upward toward the user's parietal bones to support the
parietal bones respectively. At the same time, the free end of the pressing portion
bends upward toward the external occipital protuberance and the exit occipital crest
of the user's occipital bone to press against the occipital bone. Thus, the gaps in
the user's skull are allowed to open slightly to lower the pressure of the cerebrospinal
fluid in the skull and thereby enhance circulation of the cerebrospinal fluid.
[0009] It is another objective of the present invention to provide the foregoing head relaxing
pillow, wherein the bottom of the supporting main body is further formed with a first
inclined surface which is adjacent to the user's body and which corresponds in position
to the recess. When the user's neck is resting on the supporting main body, the first
inclined surface of the supporting main body lies firmly and compliantly against a
flat surface (e.g., a bed) and serves as a fulcrum, allowing the moments of force
generated by the bending of the contact portions and the pressing portion to act precisely
on, and thereby provide sufficient support to, the user's parietal bones and the occipital
bone respectively.
[0010] Yet another objective of the present invention is to provide the foregoing head relaxing
pillow, wherein the top of the supporting main body is provided with a second inclined
surface. When the pressing portion presses against the user's occipital bone due to
the sagging of the supporting main body, the second inclined surface of the supporting
main body lies compliantly against and thereby presses against the portion of the
user's head that corresponds in position to the external occipital protuberance.

DETAILED DESCRIPTION OF THE INVENTION
[0012] The present invention relates to a head relaxing pillow. Referring to FIG. 3 for
the first preferred embodiment of the present invention, the head relaxing pillow
3, which is generally U-shaped and made of an elastic material, includes four parts,
namely a supporting main body 31, two contact portions 32, and a pressing portion
33. The principles of the present invention lie in craniosacral therapy, and the intended
effects include releasing the pressure within the user's head and promoting circulation
of the cerebrospinal fluid. The present invention allows the user to experience craniosacral
therapy, which traditionally must rely on the hands of a professional physical therapist.
[0013] Referring to FIG. 3 through FIG. 6, the top of the supporting main body 31 is configured
for supporting the neck of a user who assumes a face-up recumbent position. The bottom
of (the supporting main body 31 is concavely provided with a recess 310. In this embodiment,
the recess 310 extends through the middle portion of the bottom of the supporting
main body 31 and is generally rectangular, and yet the configuration of the recess
310 is not limited to that shown in FIG. 4 and FIG. 5). The supporting main body 31
is provided with a pair of sunken portions 311 which are respectively adjacent to
two corresponding ends of the supporting main body 31 and which correspond in position
to the user's temporal bones respectively. (The distance W between the outer edges
of the sunken portions 311 ranges from 14 to 20 cm and can be adjusted as appropriate.)
When the user's head is resting on the pillow 3, the temporal bones (which correspond
in position to the ears respectively) should be received in the sunken portions 311
respectively.
[0014] Each contact portion 32 has one end (hereinafter referred to as the first end) connected
to one of the two corresponding ends of the supporting main body 31, wherein the first
ends of the contact portions 32 are spaced apart by a first predetermined distance
D1. The other end (hereinafter referred to as the second end) of each contact portion
32 extends away from the supporting main body 31, and the second ends of the contact
portions 32 are spaced apart by a second predetermined distance D2. The second predetermined
distance D2 is less than the first predetermined distance D1 such that the contact
portions 32 correspond in configuration to the user's two parietal bones respectively
and can support the user's head.
[0015] Referring to FIG. 3 and FIG. 6, the pressing portion 33 extends from one side (hereinafter
referred to as the first side) of the supporting main body 31 and is located between
the contact portions 32. When the user U rests his head on the pillow 3, facing up,
the user U's neck and head are respectively supported by the supporting main body
31 and the contact portions 32. In the meantime, the user U's temporal bones correspond
in position to the sunken portions 311 respectively and are free from compression
by the supporting main body 31. Referring to FIGS. 3, 4, 6, and 7A, the supporting
main body 31 can sag toward the recess 310 due to the weight of the user U's neck,
causing the two corresponding ends of the supporting main body 31 to bend upward.
Consequently, the second ends of the contact portions 32 bend upward toward the user
U's parietal bones to support the two parietal bones respectively. The pillow 3 ends
up in the shape shown in FIG. 7B.
[0016] As the portion of the supporting main body 31 that corresponds in position to the
recess 310 can lie against a flat surface below the pillow 3 (e.g., a bed) to serve
as a fulcrum, the free end of the pressing portion 33 (i.e., the end away from the
supporting main body 31) in this state will bend upward toward the user U's occipital
bone, pressing against the portion of the occipital bone that is adjacent to the external
occipital protuberance. Thus, referring to FIG. 3 and FIG. 7B, when the user U assumes
a face-up recumbent position, with the neck and head resting on the pillow 3, the
temporal bones TB are respectively and relaxedly located in the sunken portions 311,
and the parietal bones PB are respectively supported on the contact portions 32. In
the meantime, with the bending of the pillow 3, the pressing portion 33 presses against
and supports the portion of the occipital bone OB that is adjacent to the external
occipital protuberance and the exit occipital crest, and the supporting force of the
pressing portion 33 generates an outward moment of force (i.e., toward the upper left
corner of FIG. 7B) acting on the user U's parietal bones PB. The portions of the contact
portions 32 that respectively support the user's parietal bones PB also generate an
outward moment component. These moments of force cause the gaps in the user U's skull
(i.e., the gap between the two parietal bones and the gap between the parietal bones
and the occipital bone) to open slightly, thereby reducing and regulating the internal
stress within the user U's head (i.e., the pressure of the cerebrospinal fluid in
the skull) and promoting circulation of the cerebrospinal fluid.
[0017] Besides, in the above embodiment, when the pressing portion 33 is pressing against
the occipital bone OB of the user U's head, the pressing force produced by the pressing
portion 33 and applied to the occipital bone OB is able to slightly disengage the
occipital bone OB from the user U's atlas (i.e. the first cervical vertebra), so as
to decompress the occipital condylar region below the occipital bone OB and then release
the cranial base and tissues around the jugular foramena of the user U accordingly.
Since the glossopharyngeal nerves, vagus nerves and accessory cranial nerves (i.e.
the ninth , tenth and eleventh pairs of cranial nerves) of human body are all passing
through the jugular foramena, release of any compromise of these tissues around jugular
foramena often has a beneficial effect on the functions of these nerves respectively.
[0018] In this embodiment, referring to FIGS. 1 and 3∼7B, the depth D3 of the recess 310
is about 1-5 cm, and the bottom of the supporting main body 31 is further formed with
a first inclined surface 312 which is adjacent to the user U's body and which corresponds
in position to the recess 310. When the user U's neck is resting on the supporting
main body 31, the supporting main body 31 lies firmly and compliantly against the
flat surface thanks to the first inclined surface 312 (it is also feasible to form
the recess 310 only on the other side of the supporting main body 31, i.e., the side
adjacent to the user, so as to increase the degree of tilting), allowing the moments
of force generated respectively by the bent contact portions 32 and the bent pressing
portion 33 to act respectively and precisely on the user U's parietal bones PB and
external occipital protuberance, thus providing sufficient support for the parietal
bones PB and the occipital bone OB respectively. In addition, the top of the pressing
portion 33 is provided with a second inclined surface 331, and the length L of the
pressing portion 33 that extends from the first side of the supporting main body 31
ranges from 1 to 4 cm. When the pressing portion 33 presses against the user's occipital
bone OB due to the sagging of the supporting main body 31, the second inclined surface
331 of the pressing portion 33 functions as a therapist's fingers lying compliantly
against and thereby pressing the portions of the user's head that are adjacent to
the external occipital protuberance EOP and the exit occipital crest EOC (the pressed
positions should not go beyond the jugular processes OB1 of the occipital bone OB,
i.e., where the occipitomastoid sutures OS lie).
[0019] The pillow of the present invention can be customized according to the user's bodily
shape (e.g., the stature, head shape, torso). In particular, adjustment can be made
to the second predetermined distance D2 between the second ends of the contact portions
32, the extension length L of the pressing portion 33, and the depth D3 of the recess
310. In this embodiment, the pillow 3 further includes a fastening strap 34 whose
two ends are respectively and movably connected to the second ends of the contact
portions 32 (e.g., via Velcro or by inserting through a fastening ring on each contact
portion 32). With the fastening strap 34, the user can adjust the second predetermined
distance D2 between the contact portions 32. For example, the second predetermined
distance D2 can be reduced for a user with a relatively pointed head in order for
the contact portions 32 to support the user's parietal bones PB respectively. Conversely,
the second predetermined distance D2 can be increased for a user with a relatively
flat head in order to support the parietal bones PB without pressing too tight.
[0020] It should be pointed out that, while the sunken portions 311 in the foregoing embodiment
are circular cavities in which the temporal bones TB of a user resting his head on
the pillow 3 can respectively stay without the skin outside the temporal bones TB
being in contact with the surface of the supporting main body 31, the configuration
of the sunken portions 311 is not limited to the above. Moreover, the pillow 3 may
be enclosed in a layer of cloth for esthetic reasons, and in that case, the skin outside
the temporal bones TB of a user resting his head on the pillow 3 may be in contact
with the cloth. However, as long as the portions of the pillow 3 that correspond in
position respectively to the temporal bones TB are provided with the sunken portions
311, the user's temporal bones TB can still stay in a relaxed state. That is to say,
the layer of cloth will not interfere with the intended functions of the pillow 3.

numerous modifications and variations could be made thereto by those skilled in the
art without departing from the scope of the invention set forth in the claims.
