As illustrated in
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.
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.
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.
As illustrated in
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.
As shown in
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
An explanation will be next given of how to use the training apparatus 1 based on
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.
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° and unstable, it is possible to strength both the wrists and forearm muscles at the same time.
Moreover, in this embodiment, since the handles 5, 5 are rotatable in both directions at 360°, 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.
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.
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.
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.
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.
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.
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.
FIGS. 17 to 21 illustrate modified examples of the first embodiment.

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.
In the example shown in
It should be noted that the examples shown in
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.
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.
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.
An explanation will be next given of a second embodiment of the present invention.

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
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.
An explanation will be next given of how to use this training apparatus 101 based on
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.
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.
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.
In addition, the training apparatus 101 has advantages of a extremely simple structure, low manufacturing cost, and easy movement.
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.
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.

An explanation will be next given of a third embodiment of the present invention.
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.
As illustrated in
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.
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.
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.
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.
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.
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.
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.
The training apparatus 201 has advantages of the extremely simple structure, low manufacturing cost and easy movement.
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.
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.
An explanation will be next given of a forth embodiment of the present invention.
As illustrated in
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.
As illustrated in
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.
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.
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.
As illustrated in
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.
The training apparatus 301 has advantages of the extremely simple structure, low manufacturing cost and easy movement.
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.
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.
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.
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.
Furthermore, the training apparatuses of the present invention can be also used in any training other then judo training.
INDUSTRIAL APPLICABILITYIn 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.
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.
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.
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.
