ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a chair type air massager including a leg massage device.
As shown in
FIG. 11
, in a conventional chair type air massager, massage bags
4
to
8
are embedded in a seat
2
and a back rest
3
of a chair body
1
. A leg massage device
9
is mounted to a front end of the seat
2
of the chair body
1
such that the leg massage device
9
can vertically rotate in a predetermined range. The leg massage device
9
includes a pair of leg accommodating grooves
10
which are capable of accommodating calves of a user sitting on the seat
2
. In the leg massage device
9
, a leg massage bag
11
is provided on each inner side surface of each of the pair of leg accommodating grooves
10
.
A handle
12
for operating a rotating motion of the leg massage device
9
is provided at one side surface of the seat
2
. By operating the handle
12
, the leg massage device
9
is vertically rotated at the front end of the seat
2
between a vertical position in which the leg massage device
9
extends downwards so that the leg accommodating grooves
10
are vertically extended as shown in
FIG. 11
, and a horizontal position in which the leg massage device
9
is extended forwards from the front end of the seat
2
in a substantially horizontal direction so that the leg accommodating grooves
10
are extended in back and fourth directions.
The leg massage device
9
of such a conventional chair type air massager is disposed in the horizontal position when it is used.
If an operation device of the chair type air massager is operated, compressed air is supplied to or discharged from the massage bags
4
to
8
and
11
by an air supply/discharge device (not shown) provided in the seat
2
. These massage bags
4
to
8
and
11
are repeatedly expanded and contracted, thereby massaging portions of the sitting user corresponding to the massage bags
4
to
8
and
11
.
When the leg massage device
9
is not used, the leg massage device
9
is disposed in the vertical position shown in FIG.
11
. By the above-described operation device, it is possible to select the massage bags
4
to
8
and
11
to and from which the compressed air is supplied and discharged, and to select the time interval during which the compressed air is supplied to and discharged from the selected massage bag or bags.
As described above, the leg massage device
9
includes three side walls at opposite sides of the pair of leg accommodating grooves
10
and between them. Therefore, when the leg massage device
9
is disposed in the vertical position for using only the massage bags
4
to
8
of the chair body
1
without using the leg massage device
9
, the sitting user is forced to locate his or her calves along the pair of leg accommodating grooves
10
of the leg massaging device
9
in the vertical position. This is because, if the calves are not located in this manner, the calves of the sitting user abut against the three side walls of the leg massage device
9
which project forwards from an under region of the seat
2
, so that the user feels unpleasant. Therefore, the sitting user who is forced to locate his or her calves as described above can not sufficiently relax when the leg massage device
9
is not used.
Further, the massage bag
11
in the leg massage device
9
rotatably mounted to the front end of the seat
2
can not be moved along a longitudinal direction of the leg accommodating groove
10
corresponding to the massage bag
11
. Therefore, when the leg massage device
9
is used, only longitudinally intermediate portions of the calves of the sitting user are massaged, and it is difficult to massage ankle portions or thigh portions of the legs of the sitting user.
The present invention has been derived from the above-described circumstances, and an object of the present invention is to provide a chair type air massager in which a leg massage device can be disposed without hindering the calves of a sitting user and whose leg massaging device can be used without requiring of the user to sit on the chair body.
BRIEF SUMMARY OF THE INVENTION
To achieve the above-described object of the present invention, a chair type air massager of the present invention comprises:
a chair body including a seat, a back rest and a plurality of massage bags embedded therein;
a leg massage device including at least one leg accommodating groove and at least one massage bag provided in correspondence to the at least one leg accommodating groove, the leg massage device being capable of moving between a first position where the leg massage device is disposed in front of the seat and is connected to the chair body, and a second position where the leg massage device is separated from the chair body, the leg accommodating groove being capable of accommodating therein at least one leg of a user sitting on the seat of the chair body when the leg massage device is disposed in the first position, and the leg accommodating groove being capable of accommodating therein at least one leg of a user who is not sitting on the seat of the chair body when the leg massage device is in the second position; and
a compressed air supply/discharge device for supplying and discharging compressed air to and from the plurality of massage bags of the chair body and the at least one massage bag of the leg massage device.
In the chair type air massager according to the present invention constructed in the above-described manner, the leg massage device is capable of moving between the first position where the leg massage device is disposed in front of the seat and is connected to the chair body, and the second position where the leg massage device is separated from the chair body. The leg accommodating groove is capable of accommodating therein at least one leg of a user sitting on the seat of the chair body when the leg massage device is disposed in the first position, and the leg accommodating groove is capable of accommodating therein at least one leg of a user who is not sitting on the seat of the chair body when the leg massage device is in the second position.
Therefore, in the chair type air massager according to the present invention, when the leg massage device is not used and only the plurality of the massage bags of the chair body are used to massage the body of the user sitting on the chair body, the leg massage device can be disposed in the second position separated from the chair body. The leg massage device disposed in the second position does not hinder the calves of the sitting user.
Further, in the chair type air massager of the present invention, at least one leg of a user who is not sitting on the seat of the chair body can be accommodated in the leg accommodating groove disposed in the second position. Therefore, the leg massage device can be utilized even if the user does not sit on the chair body, and an arbitrary portion of the leg of the user of the leg massage device can be massaged by the massage bag of the leg massage device.
In the chair type air massager of the present invention characterized in the above-described manner, the leg massage device is preferably provided with a pair of leg accommodating grooves which are substantially parallel to each other, and a plurality of massage bags are preferably provided in correspondence to each of the plurality of leg accommodating grooves.
In the chair type air massager of the present invention characterized in the above-described manner, the air supply/discharge device is preferably provided in the chair body, and the chair type air massager further comprises a high pressurized air transmitting tube having one end detachably connected to the air supply/discharge device and the other end extending from the one end to outside of the chair body and connected to at least one massage bag of the leg massage device.
Such an air supply/discharge device can commonly act on the plurality of massage bags of the chair body and the at least one massage bag of the leg massage device. Therefore, a structure of the chair type air massager acc
