BEST MODE FOR CARRYING OUT THE INVENTION
[0034] The following will explain embodiments of the present
invention based on drawings. FIG. 1 is a whole perspective view of
a training apparatus 1 according to a first embodiment of the
present invention. FIG. 2 is a partial expanded plane view of the
training apparatus 1. FIGS. 3 and 4 are partial expanded
cross-sectional views of FIG. 2, respectively. FIG. 5 is a partial
expanded perspective view of the training apparatus 1. FIG. 6 is a
view explaining how to use the training apparatus 1.
[0035] As illustrated in FIG. 1, the training apparatus 1 includes
a bar 2 made of material having rigidity such as metal. The bar 2
is formed to be longer than a shoulder width of a training
exerciser of average build. Thereby, the bar 2 is projected on both
sides from the training exerciser by about several tens
centimeters, in a state that the bar 2 is horizontally placed in
front of the training exerciser.
[0036] A press operation section 3 is attached to a central portion
of the bar 2 in its longitudinal direction. The press operation
section 3 is made of material having rigidity such as metal. The
press operation section 3 has a thin and long handle bar 4
(rotational member), which extends in parallel to the bar 2, and
handles 5, 5 attached to both ends of the handle bar 4.
[0037] A cylindrical supporting member 6 is fixed to the central
portion of the bar 2 in the longitudinal direction. As illustrated
in FIG. 2, the supporting member 6 has a projecting portion 6a
which projects in the outer direction of the supporting member 6.
The handle bar 4 is attached to a top end portion of the projecting
portion 6a with a screw 7 (rotation shaft).
[0038] As illustrated in FIG. 3, thrust bearings 8 are inserted
between the projecting portion 6a and the handle bar 4 and between
a head portion 7a of the screw 7 and the handle 4, respectively.
The handle bar 4 can smoothly rotate about a shaft portion 7b of
the screw 7 which is perpendicular to the bar 2.
[0039] As illustrated in FIG. 4, the handle 5 has a rectangular
shape formed by combining a plurality of rods. A grasped portion
5a, which the training exerciser grasps with the hand, is
cylindrically formed. A central portion in the longitudinal
direction of a front portion 5b, which faces to the grasped portion
5a, is attached to the end portion of the handle bar 4 with a screw
(spindle) 9.
[0040] In other words, a through hole 5c is formed in the central
portion of the front portion 5b in the longitudinal direction. A
cylindrical liner 10 with a hat-shaped cross section is fitted into
the through hole 5c so as not to rotate. The liner 10 is made of
material with a low coefficient of friction and a shaft portion 9b
of the screw 9 (parallel to the shaft portion 7b of the screw 7) is
rotatably fitted in the liner 10.
[0041] A screw hole 11 is formed in an end portion of the handle
bar 4. The top end of the shaft portion 9b of the screw 9 is fitted
into the screw holes 11. Minute clearances are formed between the
handle bar 4 and the front portion 5b of the handle 5 and between
the linear 10 and a head portion 9a of the screw 9, respectively.
The handle 5 can smoothly rotate about the shaft portion 9b of the
screw 9.
[0042] It should be noted that a plurality of screw holes 11 are
formed at predetermined intervals in each of the end portions of
the handle bar 4 in the longitudinal direction. By changing the
screw hole 11 into which the screw 9 is fitted, the position of the
handle 5 can be changed.
[0043] As illustrated in FIG. 1, arms 12, which intersect with the
bar 2 and extend in parallel to each other, are fixed to the right
and left ends of the bar 2, respectively. A through hole 12a is
formed in the top end portion of each of the arms 12, and an
annular end portion 13a of a wire 13 is attached to each through
hole 12a. The other end portions 13b of the wire 13, 13 are
connected to the top end portions of a pair of ropes 15, 15 drawn
from a weight training machine 14 (load application section),
respectively.
[0044] This weight training machine 14 includes a pair of weight
lifting sections 16, 16, which are vertically arranged respectively
right and left with a space interposed in between, a pair of guide
bars 17, 17, which are vertically arranged on respective right and
left sides, thereby interposing the weight lifting sections 16, 16
in between, and a rope guide section 18, which is liftably provided
with being hung across these bars 17 and 17.
[0045] As shown in FIG. 5, each of the weight lifting sections 16
includes a pair of right and left guide bars 19, 19, which are
vertically arranged, a weight support section 20, which is liftably
attached to the guide bars 19, 19, a plurality of plate-shaped
weights 21, 21, . . . , which are placed under the weight support
section 20, which are liftably engaged with the guide bars 19, 19,
and which are above and below stacked on one another, and a rope
guide device 22 attached to upper ends of the guide bars 19,
19.
[0046] A rectangular plate member 23 is fixed to a floor surface of
a training room along a wall surface W, and the guide bars 19, 19
are arranged on the upper surface of the plate member 23 in a
standing manner.
[0047] Furthermore, a rectangular plate member 24 is horizontally
fixed to the wall surface W of the training room. Thus, the
rectangular plate member 24 is placed vertically above the plate
member 23, and the rope guide devices 22 are attached to the front
surface of the plate member 24.
[0048] The weight support sections 20 are liftably engaged
respectively with the guide bars 19, 19. Each of the weight support
section 20 has a pair of right and left bearing plates 25, 25, and
the bearing plates 25, 25 pivotably support a pulley 26, thereby
being arranged vertically and rotatably. Furthermore, a shaft 27
which passes through each of the weights 21 is projected vertically
downward from the lower surface of the weight support section
20.
[0049] In the shaft 27, through holes 27a, 27a, . . . , which pass
therethrough in the back and forth direction, are formed at
periodical intervals in the axial direction, and each of the
intervals is equal to the thickness of one weight 21.
[0050] Each of the weights 21 is provided with a pin insertion
through hole 21a, which passes therethrough in the back and forth
direction, and a shaft insertion through hole 21b, which passes
therethrough in the up and down direction, and through which the
shaft 27 passes.
[0051] When the weight support section 20 comes into contact with
the upper surface of the weight 21 placed at the uppermost position
in a state where the weights 21 are above and below stacked on one
another, each of the through holes 27a of the shaft 27 matches any
one of the pin insertion through holes 21a of the respective
weights 21. If a pin 28 is inserted into the pin insertion through
hole 21a of an arbitrary weight 21, the pin 28 passes through the
weight 21 and the shaft 27. Thus, the top end portion thereof is
projected to the back of the shaft 27.
[0052] When the weight support section 20 rises in this state, the
weight 21 in which the pin 28 is inserted and all the weights 21
placed thereabove rise together in a state where they are hung from
the weight support section 20. Accordingly, by changing the weight
21 into which the pin 28 is inserted, it is possible to control the
number of weights 21 to be hung from the weight support section
20.
[0053] Each of the rope guide devices 22 includes a housing 29,
which is fixed to the plate member 24 and the upper end of each of
the guide bars 19, 19, a bearing section 30, which is pivotally
supported by the housing 29 so that it is rotatable in the
horizontal direction, and a pulley 31 which is pivotally supported
by the bearing section 30, thereby being arranged vertically and
rotatably.
[0054] The upper ends of the guide bars 17, 17 are fixed to the
plate member 24 with supporting members 32 and the lower ends
thereof are fixed to the plate member 23.
[0055] The rope guide section 18 includes a plate-shaped supporting
member 34, which is horizontally and liftably provided to the guide
bars 17, 17, a pair of holders 35, 35, which are respectively
attached to both right and left ends of the front surface of the
supporting member 34, bearing sections 36, each of which is
pivotally supported by each of the holders 35 to be rotatable in
the horizontal direction, pulleys 37, each of which is pivotally
supported by each of the bearing sections 36, thereby being
arranged vertically and rotatably, bearing sections 38, which are
respectively fixed to the upper portions of both right and left
ends of the supporting member 34, and pulleys 39, each of which is
pivotally supported by each of the bearing sections 38, thereby
being arranged vertically and rotatably.
[0056] In addition, a gate section 40 is formed in the front end
portion of each of the bearing sections 36. The gate section 40
guides, in the forward direction, the rope 15 drawn from the pulley
37. Moreover, a guide rod 41 is formed in the front end portion of
each of the bearing sections 38, and a space is formed between the
pulley 39 and the guide rod 41. Thus, the rope 15 is passed through
the space.
[0057] The rope 15 drawn to the gate section 40 is bound around an
outer periphery portion of the pulley 37, and is engaged with an
outer periphery portion of the pulley 39 after passing through a
through hole 35a at the top portion of the holder 35. Then, the
rope 15 is bound around an outer periphery portion of the upward
pulley 31, thereby extending downward. Subsequently, the rope 15 is
bound around an outer periphery portion of the pulley 26, thereby
extending upward. Thus, the upper end of the rope 15 is attached to
a lower surface of the housing 29.
[0058] When the rope 15 drawn from the gate section 40 is pulled
forward, the weight support section 20 and the weights 21 hung
therefrom are lifted up. Meanwhile, when a pulling force of the
rope 15 is loosened, the weight support section 20 and the weights
21 are lifted down.
[0059] An explanation will be next given of how to use the training
apparatus 1 based on FIG. 6. When a training exerciser grasps the
handles 5, 5 of the press operation section 3 with both hands and
pushes the handles forward, a pushing force is transmitted to the
bar 2 through the supporting member 6 and further transmitted to
the ropes 15, 15 (see FIG. 5) through the arms 12, 12, and the
wires 13, 13.
[0060] This applies an upward force to each of the weight support
sections 20, thereby lifting up the weight support sections 20 and
the weights 21 hung therefrom. Thus, the weight thereof acts on
each of the ropes 15, 15. The weight is transmitted to the both
ends of the bar 2 through each of the wires 13, 13, and each of the
arms 12, 12, thereby applying a backward load to the bar 2.
[0061] The training exerciser repeats motions of pressing the press
operation section 3 forward with both arms thrust out in order to
overcome this load, thereby making it possible to build up muscles
of the upper extremities and the trunk. Moreover, since the press
operation section 3 is rotatable in both directions at 360.degree.
and unstable, it is possible to strength both the wrists and
forearm muscles at the same time.
[0062] Moreover, in this embodiment, since the handles 5, 5 are
rotatable in both directions at 360.degree., it is possible to
rotate the wrists. Accordingly, since angles of wrists and arms
come close to those of wrists and arms at the time of grabbing a
judo uniform, it is possible to perform training in motions and
images, which are extremely similar to motions of pushing and
pulling performed in a judo match. In addition, when cloth made of
the material same as that of the judo uniform is put around the
grasped portions 5a of each handle 5, it is made possible to
perform training in the images more similar to those of the actual
judo matches.
[0063] Moreover, since the training exerciser firmly grasps the
handles 5, 5 and thrusts out the arms in pressing the press
operation section 3a, it is possible to strengthen grasping power
and to build up muscles of shoulders. Still moreover, since it is
necessary to brace the feet for balance in pressing the press
operation section 3a, it is possible to build up not only the
muscles of the upper half of the body but also those of the lower
half of the body. Particularly, it is possible to build up
bronchial muscles, forearm muscles, rectus abdominal muscles,
greater pectoral muscles, broadest muscles of back, and the
like.
[0064] Furthermore, in this embodiment, a load is applied by
pulling both ends of the bar 2 via the ropes 15, 15. Thus, the bar
2 is unstable enough to be swung in a vertical plane, when the
press operation section 3 is operated. The above-mentioned
structure is useful for strengthening, particularly, the lower part
of the body.
[0065] By performing training with this training apparatus 1, it is
possible to build up strength to stretch the arms against the
opponent's pulling and pushing in the judo match.
[0066] In addition, the amount of the load to be applied to the bar
2 in the weight training machine 14 can be controlled by changing
the number of weights 21 to be hung from the weight support section
20. Moreover, the height of the ropes 15, 15 from the floor surface
can be controlled by lifting up and down the supporting member 34
of the rope guide section 18.
[0067] Furthermore, in this embodiment, the bearing sections 36,
36, which support the pulleys 37, 37 of the rope guide sections 18,
are movable in the horizontal direction. Accordingly, the degree of
safety is high since no excessive resistance is caused by the
detachment and twisting of the wires 13, 13, in the case where the
training exerciser changes directions of thrusting out the
arms.
[0068] In addition, it is possible to know the amount of the load
to be applied to the bar 2 by measuring the weight of the weights
21. This makes it possible to perform training with high
rationality based on the numerical reason.
[0069] FIGS. 17 to 21 illustrate modified examples of the first
embodiment.
[0070] In the example illustrated in FIG. 17, the supporting member
6 can be rotated about the central axis of the bar 2 and fixed at
an arbitrary position. The press operation section 3 is rotated
about the central axis of the bar 2 at about 180.degree. and fixed
at the corresponding position. When a pulling force is applied, in
the direction of an arrow, to the bar 2 with the press operation
section 3 at this position, a load acting against the pulling force
is applied to both ends of the bar 2 with the weight training
machine 14 (see FIG. 1). This configuration makes it possible to
perform training in a motion similar to a motion performed when one
pulls the opponent by grasping the opponent with both hands.
[0071] In the example shown in FIG. 18, in place of the press
operation section 3, a press operation section 42 for one hand
operation can be rotatably attached with the screw 7. This press
operation section 42 is formed in the manner similar to the handle
5 of the press operation section 3 and the training exerciser
operates the press operation section 42 with one of the hands
grasping it. This configuration makes it possible to perform
training in a motion similar to a motion performed when one pushes
the opponent by grasping the opponent with one of the hands.
[0072] In the example shown in FIG. 19, a pair of handles 5 can be
attached to the handle bar 4 in a way that there is a distance X,
in an axial direction of the screw 7, between one of the handles 5
and the other thereof. In other words, it is possible to insert a
spacer 50 with a height corresponding to the distance X between one
of the handles 5 and the handle bar 4. This configuration makes it
possible to perform training with one arm stretched out and the
other arm bended. Thereby, it is possible to perform training
corresponding to various styles of judo matches.
[0073] In the example shown in FIG. 20, provided is an amount-of
exercise display section 43 which calculates training exerciser's
amount-of exercise and displays the calculated result. The
amount-of exercise display section 43 includes a counter 44, which
counts the number of weights 21 to be lifted up and down and the
number of up-and-down movements, a counter circuit 45, which
calculates amount-of exercise based on a value detected in the
counter 44, and a display device 46, which displays the amount-of
exercise calculated by the counter circuit 45.
[0074] Note that, the counter circuit 45 and the display device 46
may be designed for exclusive use, or only software may be newly
created by using a general personal computer. Moreover, although
the amount-of exercise to be displayed is not particularly limited,
it is possible to display, for example, the number of up-and-down
movements, a total weight, a kinetic energy (calories), and the
like. This makes it possible to perform training with high
rationality based on the numerical reason.
[0075] In the example shown in FIG. 21, provided is a doll
attaching section 48 for attaching, to the bar 2, a doll 47 which
is a virtual opponent. The doll attaching section 48 is rod-shaped.
One end of the doll attaching section 48 is fixed to an outer
surface of the supporting member 6, while the other end is
projected in the direction perpendicular to the bar 2. The doll 47
is placed in front of the training exerciser, thereby facing with
the training exerciser. Thus the doll 47 is fixed to the top end of
the doll attaching section 48 by a fixing member 49. This
configuration makes it possible to perform training in images of
actual matches.
[0076] It should be noted that the examples shown in FIG. 17 to 21
may be carried out singly or in any combination of some of
them.
[0077] Furthermore, a configuration may be made in which the amount
of the load acting on one end of the bar 2 and that of the load
acting on the other end thereof become instantaneously unbalanced
depending on the pressing force and the pulling force acting on the
bar 2. This configuration makes it possible to perform training
similar to various motions in the actual judo matches.
[0078] As a mechanism which offers the aforementioned function and
effect, for example, a clutch mechanism is provided at one weight
lifting section 16. When a speed of a wire 15 connected to the
weight lifting section 16 exceeds a certain speed, the clutch
mechanism is actuated to interrupt the transmission of the load to
the wire 15.
[0079] Furthermore, it is safe to provide a mechanism which
prevents the weights 21 from suddenly falling down in the case of a
sudden stop of the operation pushing and pulling the bar 2. As the
above-explained mechanism, a flyweight and a brake shoe are
provided in a pulley which guides the wire 15. The flyweight
oscillates when a centrifugal force reaches a predetermined value
or more, and the brake shoe catches and holds the wire 15 when the
flyweight oscillates.
[0080] An explanation will be next given of a second embodiment of
the present invention. FIG. 7 is a whole perspective view of a
training apparatus 101 according to the second embodiment of the
present invention. FIG. 8 is a plane view of the training apparatus
101. FIG. 9 is a side view of a stage 104 of the training apparatus
101. FIG. 10 is a view explaining how to use the training apparatus
101.
[0081] As illustrated in FIG. 7, the training apparatus 101
includes a thin and long bar 102. The bar 102 is formed to be
longer than the shoulder width of a training exerciser of average
build. Thus, the end portions of the bar 102 are projected from the
training exerciser at both sides by several tens centimeters, in a
state that the training exerciser puts the bar 102 on the
shoulders.
[0082] As illustrated in FIG. 8, the bar 102 has a main bar 102a
made of material having rigidity such as metal. Annular connection
portions 102b are formed in both right and left ends of the main
bar 102a, respectively. A plurality of string-shaped elastic
members 103, 103, . . . , which are made of rubber and the like,
are inserted to the respective connection portions 102b. Moreover,
a tube 102c, which is made of resin material and has elasticity, is
mounted on an outer periphery surface of the main bar 102a.
[0083] Reference numeral 104 denotes a stage, which is placed on
the floor surface, and which is made of a rectangular plate
material having rigidity. As illustrated in FIG. 9, a sheet member
105 (slip stopping means), which is made of material with a high
coefficient of friction, is adhered to the lower surface of the
stage 104, in order to prevent the stage 104 from slipping on the
floor surface.
[0084] An annular connection member 106 is arranged in a standing
manner at each of the corners of the upper surface of the stage
104. The elastic members 103 are connected to the connection
members 106 with connection rings 107, respectively. Each of the
elastic members 103 is inserted in the connection portion 102b and
the connection ring 107, and both ends of the elastic members 103
(not shown) are tied with each other. The elastic member 103 is
detachable from the connection ring 107 and the connection portion
102b. The amount of a load to be applied to the bar 102 can be
controlled by changing the number of elastic members 103 or by
replacing them with other elastic members.
[0085] An explanation will be next given of how to use this
training apparatus 101 based on FIG. 10. The training exerciser
steps on the stage 104, and upholds the bar 102 with the bar 102
horizontally placed on the shoulders. Thus, each of the elastic
members 103 expands within the limitation of elasticity, and
thereby a downward load occurs at both right and left ends of the
bar 102. Moreover, when the bar 102 placed on the shoulders is
swung right and left, each of the elastic members 103 is expanded
and contracted within the limitation of elasticity. As a result, a
load acting against the twist occurs on both right and left ends of
the bar 102.
[0086] It is possible to build up the muscles of the lower half of
the body and the trunk by repeating a squat exercise in which knees
are bent and stretched with the bar 102 placed on the shoulders and
also by twisting the bar 102 right and left during the squat
exercise. In addition, the bar 102 may be swung right and left in a
state that the bar 102 is upheld at a level of the waist behind
him/her. If a body bending and stretching exercise is slowly
performed during the squat exercise, this increases a time for
which the load of the elastic member 103 acts on the lower half of
the body and the trunk, thereby providing an effective result.
[0087] By performing the aforementioned exercises, it is possible
to build up, particularly, quadriceps femoris muscles, biceps
femoris muscles (hamstring muscles), gastrocnemius muscles, soleus
muscles (calves), latissimus dorsi muscles, abdominal muscles,
gluteus maximus muscles, and the like. This makes it possible to
build up a core of the body necessary for judo, and to improve a
balance of the body when one is attacked by using a judo technique
or one competes with the opponent.
[0088] In the training apparatus 101, the elastic members 103
applies the load to the bar 102, and thereby the bar 102 can be
made relatively lightweight. Accordingly, an inertial force exerted
at the time of twisting the bar 102 is small, as compared with a
training apparatus applying a load with weights (for example, a
squat shaft, etc.). For this reason, excessive a twisting force and
a wrenching force do not act on the body, thereby making it
possible to perform training in quick motions while ensuring the
safety.
[0089] In addition, the training apparatus 101 has advantages of a
extremely simple structure, low manufacturing cost, and easy
movement.
[0090] Furthermore, it is possible to know the amount of the load
to be applied to the bar 102 by measuring the elastic force of the
elastic members 103. This makes it possible to perform training
with high rationality based on the numerical reason.
[0091] Note that, in this embodiment, the elastic members 103 are
attached to the stage 104 placed on the floor surface, but the
elastic members 103 may be attached to the floor surface with
suitable attaching means.
[0092] FIGS. 22 to 24 illustrate modified examples of the second
embodiment.
[0093] In the example shown in FIG. 22, each of the connection
portions 102b of the bar 102 is connected to each of the connection
members 106 of the stage 104 by a plurality of elastic members 103
with a plurality of connection rings 107 interposed in between. The
number of connection rings 107 and that of elastic members 103 can
be arbitrarily increased or decreased. This configuration makes it
possible to adjust a height from the stage 104 to the bar 102, and
thus to handle a plurality of training exercisers who have
different heights. Furthermore, it is possible to control the
amount of the load to be applied to the bar 102, by changing the
number of elastic members 103 or by replacing the elastic members
103 with those having a different elastic force.
[0094] In the example shown in FIG. 23, provided is an
amount-of-exercise display section 108 which calculates training
exerciser's amount-of-exercise and displays the calculated result.
This amount-of-exercise display section 108 includes a counter 109,
which counts the number of up-and-down amount-of-exercise of the
bar 102, a counter circuit 110, which calculates amount-of-exercise
based on a value detected in the counter 109, and a display device
111, which displays the amount-of-exercise calculated by the
counter circuit 110.
[0095] Note that, the counter circuit 110 and the display device
111 may be designed for exclusive use, or only software may be
newly created by using a general personal computer. Moreover,
although the amount-of-exercise to be displayed is not particularly
limited, it is possible to display, for example, the number of
up-and-down movements, a total weight, a kinetic energy (calories)
and the like. This makes it possible to perform training with high
rationality based on the numerical reason.
[0096] In the example shown in FIG. 24, the stage 104 is equally
divided into a pair of right and left divided portions 104a and
104b along a central line 112 extending in the back and forth
direction. The divided portions 104a and 104b are rotatably
connected to each other by a pair of hinges 113 provided at
respective boundary portions between the divided portions 104a and
104b. The stage 104 is foldable along the central line 112. With
this configuration, the stage 104 can be folded and made compact,
and thereby transportability and easiness of storage can be
improved.
[0097] Note that, the examples shown in FIG. 22 to 24 may be
carried out singly or in any combination of some of them.
[0098] An explanation will be next given of a third embodiment of
the present invention. FIG. 11 is a whole perspective view of a
training apparatus 201 according to the third embodiment of the
present invention. FIG. 12 is a side view of the training apparatus
201 and FIG. 13 is a view explaining how to use the training
apparatus 201.
[0099] The training apparatus 201 is used by being connected to two
fixtures S, S arranged at both ends of a space where a training
exerciser performs training. The training apparatus 201 includes a
bar 202 shorter than the distance between the fixtures S, S. The
bar 202 is formed to be longer than the shoulder width of a
training exerciser of average build. The end portions of the bar
202 are projected from the training exerciser at both sides by
several tens centimeters, in a state that the bar 202 is placed in
front of the training exerciser. Note that, as the fixtures S, S,
already-existing fixtures (for example, support legs of another
training apparatus) may be used or the one designed for exclusive
use may be used.
[0100] As illustrated in FIG. 12, the bar 202 has a main bar 202a
formed of material having rigidity such as metal. Annular
connection portions 202b are formed in both right and left ends of
the main bar 202a, respectively. A plurality of string-shaped
elastic members 203, 203 are made of rubber and the like. Each of
the elastic members 203 is attached to each of the connection
portions 202b with a connection ring 204 interposed in between.
[0101] Each of the elastic members 203 is inserted in the
connection ring 204 and bound around an outer periphery portion of
the fixture S. Then, both ends of the elastic member 203 are tied
with each other (not shown). The elastic member 203 is detachable
from the connection ring 204 and the fixture S. The amount of the
load to be applied to the bar 202 can be controlled by changing the
number of elastic members 203 or by replacing them with other
elastic members.
[0102] An explanation will be next given of how to use the training
apparatus 201 based on the training apparatus 201. The training
exerciser holds the bar 202 with both hands and performs motions
such as turning with the body centered, twisting and stepping. This
generates a load acting against these motions on both right and
left ends of the bar 202.
[0103] Since the bar 202 can be freely moved within a limitation of
elasticity of each of the elastic members 203, it is possible to
build up the muscles of the whole body. Particularly, it is
possible to build up forearm muscles, biceps brachii muscles,
triceps brachii muscles, quadriceps femoris muscles, latissimus
dorsi muscles and the like.
[0104] Moreover, in the training apparatus 201, the elastic members
203 applies the load to the bar 202, and thereby the bar 202 can be
made relatively lightweight. Accordingly, since an inertial force
exerted at the time of twisting the bar 202 is small, an excessive
twisting force and an excessive wrenching force do not act on the
body, thereby making it possible to perform training in quick
motions while ensuring the safety.
[0105] Since the training exerciser can move the bar 202 freely and
quickly, he/she can perform training in the motions and images
similar to those of the actual judo matches.
[0106] For example, a motion similar to the major outer reaping by
using the left leg can be performed in a way that one pushes the
bar 202 with left hand while stepping forward with the right foot,
and pulls the bar 202 with the right hand, thereby twisting the
body right.
[0107] Moreover, a motion similar to the throwing technique over
the right shoulder can be performed in a way that one pushes the
bar 202 with the right hand while stepping forward with the right
foot and left foot in this order, and pulls the bar 202 with the
left hand, thereby twisting the body left at a 180 degree
angle.
[0108] The training apparatus 201 has advantages of the extremely
simple structure, low manufacturing cost and easy movement.
[0109] Furthermore, it is possible to know the amount of the load
to be applied to the bar 202 by measuring the elastic force of the
elastic members 203. This makes it possible to perform training
with high rationality based on the numerical reason.
[0110] Moreover, there is also an advantage in that one can perform
training at any place if there is a place having fixtures to which
the bar 202 is connected.
[0111] An explanation will be next given of a forth embodiment of
the present invention. FIG. 14 is a whole perspective view of a
training apparatus 301 according to the fourth embodiment of the
present invention. FIG. 15 is a plane view of the training
apparatus 301. FIG. 16 is a view explaining how to use the training
apparatus 301.
[0112] As illustrated in FIG. 14, the training apparatus 301 is
used by being connected to a plurality of fixtures S', S', . . .
arranged around a space where a training exerciser performs
training. The training apparatus 301 includes a body binding
section 302 bound around the trunk of the training exerciser.
[0113] Note that, as the fixtures S', existing fixtures (for
example, support struts of another training apparatus and the like)
may be used or those designed for exclusive use may be used.
[0114] As illustrated in FIG. 15, the body binding section 302
includes a flexible tub 303, which is made of resin material, a
chain 304, which is inserted into the tube 303, and whose both ends
are projected from the tube 303, and a hook-shaped stopper 305
attached to one end of the chain 304.
[0115] The body binding section 302 is formed in an elliptic shape.
A plurality of string-shaped elastic members 306, 306, . . . ,
which are made of rubber and the like, are connected to each of the
ends of the body binding section 302 in the major axial direction
with a pair of connection rings 307, 307. Both ends of each of the
elastic members 306 are tied with each other. Each of the elastic
members 306 is inserted in the connection rings 307, 307, and
connected to the fixtures S' movably in the up and down directions
with hook-shaped connection members 308 and wires 309.
[0116] It should be noted that the elastic member 306 is detachable
from the connection rings 307 and the connection members 308. The
amount of a load to be applied to the body binding section 302 can
be controlled by changing the number of elastic members 303 or by
replacing them with other elastic members.
[0117] An explanation will be next given of how to use the training
apparatus 301. In a state that the body binding section 302 is
bound around the body of the training exerciser and fastened to a
proper degree, an appropriate portion of the other end of the chain
304 is hooked on the stopper 305, thereby the stopper 305 being
stopped.
[0118] As illustrated in FIG. 16, when the training exerciser
twists the body right and left, each of the elastic members 306 is
expanded and contracted, and thereby a load acting against the
twist acts on the body binding section 302. Since this load
directly acts on the body of the training exerciser, it is possible
to build up the muscle of the trunk without failure. Particularly,
it is possible to build up rectus abdominal muscle, oblique
abdominal muscle and the like.
[0119] Furthermore, when the training exerciser performs motions of
stepping forward or backward with any of the feet and
simultaneously twists the body, he/she can perform training in the
motions and images similar to those of the actual judo matches.
[0120] The training apparatus 301 has advantages of the extremely
simple structure, low manufacturing cost and easy movement.
[0121] Moreover, since the elastic members 306 apply the load, the
body binding section 302 is lightweight and an inertial force
exerted at the time of twisting is small. Accordingly, an excessive
twisting force and an excessive wrenching force do not act on the
body, thereby making it possible to perform training in quick
motions while ensuring the safety.
[0122] Moreover, there is also an advantage in that one can perform
training in any place if there is a place having the fixtures to
which the body binding section 302 is connected.
[0123] Furthermore, it is possible to know the amount of the load
to be applied to the body binding section 302 by measuring the
elastic force of the elastic members 306. This makes it possible to
perform training with high rationality based on the numerical
reason.
[0124] It should be noted that a structure of the present invention
is not limited to the aforementioned embodiments. Various
variations and modifications may be possible without departing from
the gist of the present invention.
[0125] Furthermore, the training apparatuses of the present
invention can be also used in any training other then judo
training.
INDUSTRIAL APPLICABILITY
[0126] In the training apparatus of the first invention, the
training exerciser grasps the press operation section with both
hands and presses it forward, so that the load in the direction
opposite to the pressing direction occurs at both ends of the bar.
The training exerciser repeats the motion of pressing the press
operation section forward in order to overcome this load, thereby
making it possible to build up the muscle of the upper extremities
and the trunk. Furthermore, since the press operation section is
rotatable and unstable, it is possible to strength both the wrists
and the forearm muscles at the same time. Moreover, since it is
necessary that the training exerciser push out both arms with the
press operation section grasped firmly with both hands, it is
possible to strengthen grasping power and the muscle of the
shoulders. Still moreover, since it is necessary that to the
training exerciser balance with the feet braced in pressing the
press operation section, not only the muscle of the upper half of
the body but also those of the lower half thereof can be
strengthened.
[0127] In the training apparatus of the second invention, the
training exerciser upholds the bar with the bar placed on the
shoulders, thereby generating a downward load at both ends of the
bar. In addition, when the bar placed on the shoulders is swung
right and left, a load acting against the twist occurs at the bar.
Thus, the muscles of the lower half of the body and the trunk can
be strengthened, by repeating a squat exercise in which knees are
bent and stretched with the bar 102 placed on the shoulders and
also by twisting the bar 102 right and left during the squat
exercise. Moreover, a similar effect can also be obtained when the
bar is swung right and left in a state that the bar 102 is upheld
at a level of the waist behind him/her.
[0128] In the training apparatus of the third invention, the
training exerciser holds the bar with both hands and performs
motions such as turning with the body centered, twisting and
stepping. This generates a load acting against these motions on the
bar. In this training apparatus, since the movement of the bar is
not limited, it is possible to build up the muscles of the whole
body and perform training in the motions and images similar to
those of the actual judo matches.
[0129] In the training apparatus of the fourth invention, the
training exerciser twists the body right and left, so that a load
acting against the twisting occurs on the body binding section.
Since the load directly acts on the body of the training exerciser,
it is possible to build up the muscles of the trunk without
failure. Furthermore, the training exerciser can perform the
motions of stepping forward or backward with any of the feet and
simultaneously can twist the body. For this reason, it is possible
to perform training in the motions and images similar to those of
the actual judo matches.
