Best Mode for Carrying Out the Invention
Now, a first embodiment of the present invention will be explained with
reference to Figs, 1 to 3.
In the above drawings, reference numeral I designates a lower mat, which is
formed at an upper end thereof with upwardly protruding shaft coupling portions
11.
To the lower mat 1 is pivotably coupled an upper mat 2 usable as a backrest.
As shown in Fig. 1, the upper mat 2 comprises a reverse U-shaped frame 21,
which is coupled at both ends thereof to the shaft coupling portions 11 by
making use of shafts 12, and an upper panel 22 attached to an upper surface
of the frame 21.
The upper panel 22 is rotatably mounted at an upper surface thereof with a
plurality of pressure rollers 25, which serve to press specific acupuncture points
distributed on the user's back.
Inside the lower mat 1 are installed a plurality of shovers (shock absorbers) 5,
and in turn, these shovers (shock absorbers) 5 are installed with pistons 4,
respectively, in an extendable or retractable manner. The pistons 4 are

integrally formed with footstools. 3, protruding upward above an upper surface
of the lower mat 1, in a one to one ratio.
To the shovers (shock absorbers) 5 is constantly applied a gas pressure for
retracting the pistons 4, and at the upper surface of the lower mat 1 are incised
longitudinal movement slots 6 for allowing movement of the footstools 3.
With such a configuration, when the user pushes out the footstools 3 with
his/her feet when sitting on the lower mat 1, the gas pressure applied to the
shovers (shock absorbers) 5 act as a resistance force, resulting in exercise for
the user's lower body, Then, as soon as a force applied to the footstools 3 by
the user is removed, the footstools 3 are returned to their original positions by
the gas pressure, Therefore, the user can constantly exercise his/her lower
body by repeating such a pushing action.
Between the lower mat 1 and the upper mat 2 are interposed plate springs 13,
which serve to constantly provide elasticity to the upper mat 2 for the rising
thereof.
Referring to Fig. 3, each of the plate springs 13 is mounted at an inner side of
the respective shaft coupling portions 11 formed at the lower mat 1, and takes
the form of a coil-so as to give rise to strong rotational elasticity. The plate
spring 13 is centrally fixed to either shaft 12, and is formed at an outermost
portion thereof with a holding recess 14, so that a holding rod 15, protruding
laterally from an inner peripheral surface of the frame 21, is caught therein,

thereby allowing the upper mat 2 to be pivoted upward by the rotational
elasticity of the plate spring 1.3.
In this way, since the upper mat 2 tends to be constantly raised by the plate
springs 13, it enables the user to reinforce his/her upper body, in particular, the
abdomen by forcibly pressing the upper mat 2 with a force of the upper body.
In this case, the upper mat 2 can be fixed at a desired inclination.
For this, as shown in Fig, 2, a pair of inclination adjustment plates 16, having a
constant size, is coupled at both sides of the upper end of the lower mat 1.
Each of the inclination adjustment plates 16 has a plurality of inclination
adjustment holes 17 aligned in an arched line. In correspondence to these
holes 17, at either side of the frame 21, is formed a hole 23 so as to selectively
coincide with one of the inclination adjustment holes 17 of the respective
inclination adjustment plates 16 according to a desired inclination of the frame
21.
Therefore, at a position where the frame 21 is raised by a desired inclination,
corresponding inclination adjustment holes 17 of the respective inclination
adjustment plates 16 coincide with the holes 23 of the frame 21, and fixing pins
18 are inserted through the coincided holes 17 and 23, thereby allowing the
upper mat 2 to be fixed at the desired inclination.
As can be clearly understood from the above description, the upper mat 2 may
be pivotably raised relative to the lower mat 1 so as to take the form of a chair,
thereby allowing the user to exercise his/her lower body when sitting on the

lower mat 1, or the upper mat 2 and the lower mat 1 may be horizontally
aligned like a bed, thereby enabling exercise of the lower body even in a
convenient lying posture.
With the exercise device of the present invention as stated above, the user can
independently exercise his/her lower body and his/her upper body by using the
footstools 3 and the upper mat 2, and if necessary, can simultaneously exercise
not only the lower body but also upper body.
Moreover, by virtue of its simple structure, the exercise device of the present
invention has low production cost and high productivity, enabling more people
to enjoy the exercise device with a low price,
Preferably, for the convenience of storage, the upper mat 2 and the lower mat I
are stackable one upon another so as to come into close contact with each
other.
Meanwhile, as shown in Fig. 4, in order to allow the abdomen and lower body
exercise device of the present invention to be usable as a substitute for a chair,
the lower mat 1 is provided with a support leg unit 24 at a lower side thereof,
and a pair of handles at both sides thereof.
Reference is now made to Figs. 5 to 10, which illustrate a chair type exercise
device in accordance with a second embodiment of the present invention.
In the above drawings, reference numeral 31 designates a body frame defining
the appearance of the exercise device. At an upper plane of the body frame 31

is disposed a seat 32, and a backrest 33 is vertically erected from a rear end of
the seat 32.
Alongside a rear end of the body frame 31 under the seat 32 is laterally
installed a rotating shaft 35, so that both ends of the rotating shaft 35 are
coupled to connector portions 34 protruding downward from opposite lateral
edges of the backrest 33, thereby causing the backrest 33 to be
correspondingly pivoted according to rotation of the rotating shaft 35. At both
ends of the rotating shaft 35 are fitted a pair of elastic members 36, which take
the form of coil springs suitable to apply elasticity to the backrest 33 required
for the raising thereof.
In addition, a first fixing lever 37 is fastened to one side of the body frame 31
for allowing selective pivoting of the backrest 33. If the first fixing lever 37 is
tightened, the backrest 33 is fixed in its present state, whereas if the first fixing
lever 37 is released, the backrest 33 is pivotable.
Therefore, in a released state of the first fixing lever 37, the user can effectively
perform abdominal exercise by pushing the backrest 33 downward when sitting
on the seat 32.
That is, since the backrest 33 tends to be constantly raised by the elasticity of
the elastic members 36, in order to lower the backrest 33, the user has to
strongly flex their abdomen sufficiently to overcome the elasticity of the elastic
members 36, resulting in abdominal exercise.
Meanwhile, under the seat 32 is longitudinally installed a guider 38; which is,
fastened at one surface thereof with a second fixing lever 39. In. the guider 38

is inserted a footstool support 40 in an extendable or retractable manner, and in
turn, to an end of the footstool support 40 is coupled a footstool rod 41 so as to
extend perpendicular thereto.
Therefore, in a state wherein the footstool support 40 is maximally extended
from the guider 38 as shown in Fig. 9, the user can perform abdominal exercise
by pushing the backrest 33 downward with his/her back while putting his/her
feet on the footstool rod 41. With such a posture, the user can push the
backrest 33 by applying a more strong force while simultaneously applying a
strong force to his/her legs, resulting in effective exercise of his/her lower body
as well as abdominal exercise.
As shown in Figs. 7-10, a plurality of acupressure means 42 includes a plurality
of acupressure members 43 attached to the surface of the backrest 33. The
acupressure members 43 are made of a material selected from among jade,
magnets, wood, metal, or the like; and covers 44 are attached to the backrest
33 to wholly wrap the acupressure members 43, respectively.
Alternatively, as shown in Figs. 11 and 12, each of the acupressure means 42
includes a roller housing 50 and an acupressure roller 51. The roller housing 50
is embedded in the surface of the backrest 33, and the acupressure roller 51 is
rotatably supported in the roller housing 50 by means of a shaft. From an outer
surface of the acupressure roller 51 protrude a plurality of bosses 52 made of
jade or magnets.
