Cushion for relieving fatigue and reforming sleeping position

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is directed to a cushion for relieving fatigue and reforming a sleeping position, whereby a user has a good sleep while being massaged upon going to sleep, thus easily relieving his or her fatigue and correcting his or her abnormal sleeping position.

2. Description of the Prior Art

In general, since a person sleeps using only beddings and a pillow, thereby assuming an abnormal sleeping position for a considerable period of time, he or she suffers from muscle pain and does not have a good sleep, thus not recovering from his or her fatigue. In addition, accumulated fatigue causes the sleeping position to be poor.

With a view to overcoming the above problems, people have tried other sleeping positions. For example, a person elevates his or her legs on a certain support, such as a pillow or a chair, or lies on his or her side while a pillow is held in his or her arms. However, the person feels hot in summer by holding a pillow in his or her arms or legs, and since the size of the pillow is typically small, the effects of relieving fatigue and reforming the sleeping position are not achieved.

SUMMARY OF THE INVENTION

Therefore, the present invention has an object of solving the problems encountered in the prior art and providing a cushion for relieving fatigue of a user and reforming the user's sleeping position, by which the user lies on his or her side while wrapping his or her arms and legs around the cushion, thereby maintaining the spine of the user in a straight position.

It is another object of the present invention to provide a cushion for relieving fatigue and reforming a sleeping position, which is advantageous in terms of promotion of blood circulation and massaging effect by applying mechanical vibrations from the cushion placed under the legs of the user to the user.

It is still another object of the present invention to provide a cushion for relieving fatigue and reforming a sleeping position, whereby the user has a good sleep.

It is a further object of the present invention to provide a cushion for relieving fatigue and reforming a sleeping position, having a simple cushion structure and a low manufacturing cost.

It is a still further object of the present invention to provide a cushion for recovering from fatigue and reforming a sleeping position which can be easily maintained and mended.

In accordance with a primary embodiment of the present invention, there is provided a cushion for relieving fatigue and reforming a sleeping position comprising a cylindrical sponge having a predetermined length; first, second and third driving motors placed in the sponge to apply mechanical vibrations to the body of a user for relieving fatigue; a controller for controlling the first, second and third driving motors to generate the mechanical vibrations; a cylindrical plastic frame produced through a molding process and having open ends so that one end of the sponge is inserted into and fixed in the plastic frame; an inner cover covering the sponge and first and second molded bodies of the plastic frame; a vessel inserted into an end of the plastic frame and receiving a battery therein; a cap covering an opening of the vessel and equipped with an input unit and a display unit of the controller; an aromatic case mounted to the cap and having an aromatic material therein for supplying the aroma of the aromatic material; and an outer cover covering the inner cover and the plastic frame.

. Thus, the user may take a rest under a more pleasant relaxation or sleeping atmosphere.

In addition, when the user simultaneously wraps his or her arms and legs around the cushion, the spine of the user is generally straightened, thus reforming the sleeping position. Moreover, when the legs of the user are supported by the cushion, blood circulation in the legs is improved, whereby the user fully recovers from fatigue.

In a plurality of the holes

82

a

formed on the lid

82

covering the opening of the aromatic case

34

in the sponge

11

acts to massage the groin. In addition, the third driving motor

35

is placed in the sponge

11

in order to massage the legs. Thereby, each body portion of the user may be easily massaged for a predetermined time period (for applying mechanical vibrations to the user, the above three driving motors may be simultaneously or sequentially driven).

While weak vibrations are applied to the user by the first, second and third driving motors

33

,

34

and

35

, the strong button

23

C of the input unit

23

may be switched-on, whereby the first, second and third driving motors

33

,

34

and

35

are operated to generate strong vibrations in response to drive signals outputted from the first, second and third drive units

25

,

26

and

27

.

When the manual button

23

B of the input unit

23

is switched-on, operation of the first, second and third driving motors

33

,

34

and

35

is manually controlled. Such operating condition is displayed by the lighted manual mode display lamp

24

B (LED) of the display unit

24

. Also, in response to drive signals outputted from the first, second and third drive units

25

,

26

and

27

under control of the microprocessor

21

, at least one of the first, second and third driving motors

33

,

34

and

35

may be driven or all of the first, second and third driving motors

33

,

34

and

35

may be simultaneously driven for a predetermined time period, thus promoting recovery from fatigue and reforming the sleeping position.

In case power charged to the battery

22

is completely consumed, a plug of an adaptor which is not shown is inserted into the DC jack

100

, and DC power is applied to the microprocessor

21

and the battery

22

. Thereby, under control of the microprocessor

21

, at least one of the first, second and third driving motors

33

,

34

and

35

may be driven or all of the first, second and third driving motors

33

,

34

and

35

may be simultaneously driven, and also the battery

22

may be charged. When the battery

22

is replaced, a cap

110

covering a battery-accommodating chamber is opened and a spent battery may be easily replaced with a new battery.

In addition to using the cushion by holing it in arms of the user and putting one leg over a lower portion of the cushion, the cushion may be used as a support under the legs instead of a pillow, and thus the user may take a rest.

When the cushion is used as a support under the legs of the user, the heart and brain are positioned lower than the legs. Thus, blood from the legs is easily circulated to the heart and brain, and relief from fatigue may be further promoted.

Now, a description will be given of a cushion for relieving fatigue and reforming a sleeping position according to a second embodiment of the present invention, below.

22

to the microprocessor

21

and the applied power is displayed by the lighted power display lamp

24

A (LED) of the display unit

24

.

As such, drive control signals are outputted from the microprocessor

21

to the first, second and third drive units

25

,

26

and

27

by a control program stored previously in the microprocessor

21

of the controller

20

, whereby at least one of the first, second and third driving motors

33

,

34

and

35

is sequentially driven. The first, second and third drive units

25

,

26

and

27

which have received the drive control signals from the microprocessor

While the first, second and third driving motors

33

,

34

and

35

are driven in response to drive signals outputted from the first, second and third drive units

25

,

26

and

27

, weak vibrations are generated and the body of the user is massaged. Thereby, blood circulation is promoted and fatigue is relieved. As well, the user becomes healthy due to skin massage. Further, the aroma of the aromatic material mounted into the aromatic case

80

is released through a plurality of the holes

82

a

formed on the lid

82

covering the opening of the case

80

. Thus, a pleasant relaxation or sleeping atmosphere is ensured.

Moreover, when the user lies on his or her side while encircling the cushion with his or her arms and wrapping his or her legs around the cushion, the spine of the user becomes generally straight, thus correcting the sleeping position. Also, blood circulation of the legs is improved, whereby the user may recover from fatigue.

As for the cushion according to the second embodiment of the present invention, the warming or cooling sheet

120

emitting warmth or coolness is detachably mounted to the external surface of the outer cover

90

. Hence, for use in summer, cold packs

123

stored in a freezer are placed into the pockets

122

sewn on the internal surface of the multi-layered fabric sheet

121

, after which the cooling sheet

120

is wrapped around and detachably attached to an external surface of the outer cover

125

mounted at regular intervals to the internal surface of the warming or cooling sheet

120

are tightly fitted to the outer cover

90

while firmly holding the cushion in place.

In the warming or cooling sheet

120

, the hot or cold packs

123

emitting warmth or coolness are releasably placed into the pockets

122

formed on the innermost waterproof fabric layer

121

D of the fabric sheet

121

. For instance, a cooling sheet

120

provided with cold packs

123

is wrapped around the cushion, and the user holds such a cushion in his or her arms and puts one leg over a lower portion of the cushion. Thereby, coolness by the cold packs

123

placed in the pockets

122

of the cooling sheet

120

is emitted to the body of the user, thus relieving fatigue while refreshing the user in summer. Also, the spine of the user is maintained in a straight position. The mechanical vibrations generated by driving the first, second and third driving motors

33

,

34

and

35

are applied to the body of the user, and thus the user may take an enjoyable rest and may go to sleep, and also may reform his or her sleeping position.

Meanwhile, hot packs

123

are placed into the warming sheet

120

, and the user encircles the cushion covered with such a warming sheet

120

with his or her arms and legs. Thereby, warmth is emitted from the hot packs

123

placed in the pockets

122

of the warming sheet

120

to the body of the user, whereby the user may recover from fatigue while keeping himself or herself warm in winter. As well, the spine of the user becomes straight, and the mechanical vibrations generated by driving the first, second and third driving motors

33

,

34

and

35

are applied to the body of the user. So, the user may take an enjoyable rest and may go to sleep, and reform the sleeping position.

The fabric sheet

121

of the warming or cooling sheet

120

blocks penetration of water by the outermost waterproof fabric layer

121

A, and blocks entrance and exit of heat by the adiabatic nonwoven fabric layer

121

B superimposed on the waterproof fabric layer

121

A. In addition, deformation of the adiabatic nonwoven fabric layer

121

B is prevented by the fiberglass layer

121

C layered thereon. The innermost waterproof fabric layer

121

D placed on the fiberglass layer

121

C functions to prevent penetration of water. By such a layered configuration, even though the hot packs

123

in the pockets

122

of the warming sheet

120

are damaged, the user cannot but get burned.

Each slit

122

A of the pockets

122

is provided with a fastening unit for fixing the position of the packs

123

which is not shown and is exemplified by zipper, slide fastener, hook and pile pieces of Velcro fastener, fastening string, as mentioned in the primary embodiment of the present invention, whereby the position of the packs

123

inserted into the pockets

122

a

formed on the lid

82

covering the opening of the aromatic case

80

, an opening ratio of the holes

82

a

may be regulated while the slide plate

84

82

is slid in left or right directions as best seen in

FIG. 3

, thus controlling a release rate of the aroma.

While weak vibrations are applied to the user by the first, second and third driving motors

33

,

34

and

As described above, the present invention provides a cushion for relieving fatigue and reforming a sleeping position. The cushion comprises a cylindrical sponge having a predetermined length, and first, second and third driving motors placed in the sponge to apply mechanical vibrations to the body of the user for relieving fatigue. The cushion also includes a controller for controlling the first, second and third driving motors to generate the vibrations, and a cylindrical plastic frame produced through a molding process and having open ends so that one end of the sponge is inserted into and fixed in the plastic frame. An inner cover covers the sponge and first and second molded bodies of the plastic frame, and a vessel is inserted into an end of the plastic frame and receives a battery therein. A cap covers an opening of the vessel and is provided with an input unit and a display unit of the controller. An aromatic case is mounted to the cap and has an aromatic material therein for releasing the aroma of the aromatic material. And an outer cover covers the inner cover and the frame. A warming or cooling sheet, having a plurality of pockets sewn on an internal surface thereof to accommodate hot or cold packs, is detachably mounted to an external surface of the outer cover for emitting warmth or coolness to the user.

Upon going to sleep or resting, the user lies on his or her side while wrapping his or her arms and legs around the cushion of the present invention, whereby the spine of the user may be straightened, thus reforming the sleeping position of the user. Further, when the user rests his or her legs on the inventive cushion, blood circulation of the legs is improved by mechanical vibrations generated from the first, second and third driving motors. Therefore, the cushion of the present invention is advantageous in terms of low manufacturing cost, simple structure, easily reforming a sleeping position, providing a massaging effect, and being easy to maintain and mend.
