Description
FIELD OF THE INVENTION
[0001] The present invention relates generally to a pillow, and
more particularly to a pillow having a memory similar to the
so-called "plastic memory". The pillow is adjustable in height and
hardness and is capable of regaining its original form after being
deformed.
BACKGROUND OF THE INVENTION
[0002] As shown in FIG. 1, a prior art pillow 1 is made of an
artificial sponge 11 capable of providing a comfortable support to
the head, the neck, and the cervical vertebra of a user thereof.
The artificial sponge 11 has a memory.
[0003] As shown in FIG. 2, another prior art pillow 2 is made of an
artificial sponge 21 having a memory, and an artificial sponge 22
without a memory. This prior art pillow 2 is similar in function to
the prior art pillow 1 described above, even though they are
somewhat different in construction. These two prior art pillows are
not provided with means to adjust the height, the hardness, and the
softness of the pillows.
SUMMARY OF THE INVENTION
[0004] The primary objective of the present invention is to provide
a pillow which has memory and means to adjust the thickness and the
hardness of the pillow.
[0005] The pillow of the present invention comprises a first
artificial sponge layer, a second artificial sponge layer, and an
adjustment layer. The first artificial sponge layer has a memory.
The second artificial sponge layer is devoid of a memory and is
fitted into the adjustment layer which is provided with means to
inflate or deflate the pillow. The adjustment layer is fitted into
the first artificial sponge layer.
[0006] The features and the advantages of the present invention
will be more readily understood upon a thoughtful deliberation of
the following detailed description of the preferred embodiments of
the present invention with reference to the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 shows a schematic view of a prior art pillow at
work.
[0008] FIG. 2 shows a schematic view of another prior art pillow at
work. FIG. 3 shows an exploded view of a first preferred embodiment
of the present invention.
[0009] FIG. 4 shows a perspective view of the first preferred
embodiment of the present invention in combination.
[0010] FIG. 5 shows a sectional schematic view of the first
preferred embodiment of the present invention.
[0011] FIG. 6 shows a schematic view of the first preferred
embodiment of the present invention at work.
[0012] FIG. 7 shows a sectional schematic view of the adjustment
mechanism of the first preferred embodiment of the present
invention at work.
[0013] FIG. 8 shows an exploded view of a second preferred
embodiment of the present invention.
[0014] FIG. 9 shows a sectional schematic view of the second
preferred embodiment of the present invention in combination.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] As shown in FIGS. 3-7, a pillow 3 embodied in the the
present invention comprises a memory member 31, an adjustment
member 32, and a support member 33.
[0016] The memory member 31 is of a hollow construction and is made
of an artificial sponge having a memory. The memory member 31 is
provided at one of two open ends with a zipper 311.
[0017] The adjustment member 32 is of a hollow construction and is
dimensioned to fit into the hollow interior of the memory member
31. The adjustment member 32 is formed of an air duct 321, a
plurality of air sacs 322, an air valve 323, and a valve plug 324.
The air sacs 322 are in communication with the air duct 321 which
is connected with the air valve 323. The adjustment member 32 can
be inflated or deflated so as to adjust the thickness and the
hardness of the pillow 3. The air is injected into the air sacs 322
via the air duct 321 and the air valve 323, thereby resulting in
expansion of the air sacs 322. On the contrary, the air is let out
of the air sacs 322 via the air valve 323, thereby resulting in
contraction of the air sacs 322. The thickness and the hardness of
the pillow 3 are adjusted by inflating or deflating the adjustment
member 32.
[0018] The support member 33 is made of an artificial sponge and is
fitted into the hollow interior of the adjustment member 32. The
support member 33 serves to bear the pressure exerting on the
memory member 31 and the adjustment member 32.
[0019] In light of the memory member 31 coming in a direct contact
with an external force exerting on the pillow 3, the pillow 3 is
capable of regaining its original form upon being relieved of the
external force.
[0020] As shown in FIGS. 8 and 9, a pillow 3 of the second
preferred embodiment of the present invention comprises a memory
member 31, an adjustment member 32, and a support member 33.
[0021] The memory member 31 is of a hollow construction and is made
of an artificial sponge having a memory. The memory member 31 is
provided at one end with a zipper 311.
[0022] The adjustment member 32 is provided in the interior with an
air sac 322, and at one end with an inflation valve 323, which is
provided with a valve plug 324 and is connected with the air sac
322. The adjustment member 32 is expanded or contracted by
inflating the air sac 322 via the inflation valve 323, or by
deflating the air sac 322 via the inflation valve 323.
[0023] The support member 33 is of a hollow construction and is
made of an artificial sponge. The support member 33 has a hollow
interior in which the adjustment member 32 is accommodated. The
support member 33 is fitted into a hollow interior of the memory
member 31 along with the adjustment member 32.
[0024] The pillows of the present invention provide a comfortable
support to the head, the neck, and the cervical vertebra of a user
of the pillows of the present invention. In addition, the pillows
of the present invention are simple in construction and
cost-effective.
[0025] The embodiments of the present invention described above are
to be regarded in all respects as being illustrative and
nonrestrictive. Accordingly, the present invention may be embodied
in other specific forms without deviating from the spirit thereof.
The present invention is therefore to be limited only by the scopes
of the following claims.
