Summary of the Invention

Problems to be Solved by the Invention

[0005] In the above training machine, even the elderly and those with diseases can safely use the training machine by reducing the moving speed. However, in order to perform the above control, a damper must be added, which complicates the structure of the machine. Further, in order to change the moving speed according to the user and adjust the intensity of the exercise, it is necessary to adjust the damping force of the damper. However, when the adjustment is a dial type, it is difficult to understand the adjustment increment or decrement.

[0006] In view of the above, the present invention aims to provide a training machine that can adjust the intensity of exercise according to the user. [Means for solving the problem]

[0007] The training machine of the present invention comprises a weight section mounted on a main frame so as to be movable up and down, and a movable section connected to the weight section via a connecting section, the movable section being moved using the limbs, and a weight member for adjusting the exercise intensity is detachably provided on the movable section.

[0008] The connecting section comprises a guide wheel installed on the upper part of the main frame, and a cable wrapped around the guide wheel, with one end connected to the weight section and the other end connected to the moving section. The moving section is biased upward by the load of the weight section and the tensile force of the cable. The guide wheel and cable can be a pulley and a wire rope. Another embodiment of the guide wheel and cable is a sprocket and a chain. Furthermore, another embodiment of the connecting section may involve interposing an expandable member such as a coil spring between the weight section and the moving section.

[0009] The movable part comprises a handle that moves vertically by the upper limb and a base that holds the handle, the rear of which is supported by a guide column attached to the main frame so as to be slidable and rotatable horizontally. The weight member is detachably attached to the base or the handle.

[0010] The handle portion has a gripping portion that the user grasps with their hand, and the gripping portion is biased upward by the load of the weight portion. The gripping portion is attached below the base via a vertical axis. The gripping portion may be fixed to the base or supported so as to be rotatable around the vertical axis.

[0011] Another embodiment of the handle portion includes a handgrip for the user to place their hand on, which is biased upward by the load of the weight portion. The handgrip is provided above the base, and shoulder movement can be performed by pushing the handgrip downward. In this case, the rear part of the base below the handgrip is slidably supported by a guide column. Furthermore, it may be rotatably supported around the guide column.

[0012] Another embodiment of the movable part is used in a lower body training machine and comprises a slider part that moves in the forward and backward direction by the lower limbs, and a pedal part disposed above the slider part on which the user's feet are placed, wherein the slider part is slidably supported on a slide bar attached to the main frame, and the weight member is detachably attached to the pedal part.

[0013] By placing weight components in moving parts such as the handlebars and pedals, a temporary balance is created against the load of the weight components, causing the handlebars and pedals to move slowly when they begin to move.

[0014] The mass of the weight member is variable; the larger the mass of the weight member, the smaller the acceleration of the moving part, and the smaller the mass of the weight member, the larger the acceleration of the moving part. By changing the mass of the weight member, the intensity of the movement can be adjusted. The weight member is a block having a predetermined mass, and a recess formed by cutting a groove-shaped notch in a part of the block is fitted into a fixing bracket or the like provided on the moving part to support it and prevent it from slipping down. [Effects of the Invention]

[0015] According to the present invention, by providing weight members to moving parts such as the handle and pedal sections, the change in speed of the moving parts can be made more gradual compared to when no weight members are provided, and the exercise intensity can be reduced.

Mode for Carrying Out the Invention

[0017] <First Embodiment> Hereinafter, the training machine according to the first embodiment of the present invention will be described. As shown in FIG. 1, the training machine of the present embodiment is an upper body training machine. This training machine includes a weight portion 2 provided on the main body frame 1 so as to be able to move up and down, a moving portion 3 for moving the weight portion 2 up and down using the upper limbs, and a seating portion 4 on which a user who performs training using the upper limbs sits.

[0018] The main frame 1 is formed from a gantry frame 10 and a lower frame 11 that supports the gantry frame 10. Multiple blocks 12 constituting the weight section 2 are stacked and arranged in the center of the gantry frame 10 in the left-right direction. In the weight section 2, a predetermined number of blocks 12 set according to the user move up and down along a guide bar 13. A seating section 4 is provided on the lower frame 11 that protrudes forward from the gantry frame 10. A leg pad 14 is provided in front of the seating section 4 to hold down the user's thighs so that they do not lift up.

[0019] The movable part 3 consists of a handle part 20 that the user grasps with their hand, and a connecting part 21 that connects the handle part 20 and the weight part 2. The handle parts 20 are arranged in pairs, left and right. A ring-shaped grip 23, which serves as a gripping part, is suspended from the tip side of the base 22 of the handle part 20 via a vertical shaft 24. The vertical shaft 24 is rotatably supported on the base. A guide column 25 attached to the gate-type frame 10 passes through the rear of the base 22, and the base 22 is supported so that it can move up and down and rotate horizontally. As a result, the handle part 20 can slide up and down and rotate horizontally relative to the guide column 25. The grip 23 is also rotatable horizontally.

[0020] The connecting section 21 includes a guide wheel installed on the upper part of the main frame 1 and a cable that is wrapped around the guide wheel and connects the weight section 2 and the handle section 20. The cable is a wire rope 30, and the guide wheel is a plurality of pulleys 31. A wire rope 30 is used for each of the left and right handle sections 20, with one end of each wire rope 30 connected to a fixing fitting provided on the block 12 at the top of the weight section 2, and the other end connected to a fixing fitting 32 provided on the upper surface of the base 22 of the handle section 20. Each pulley 31 is installed on the upper part of the gate-type frame 10, and the wire rope 30 connected to the block 12 is wrapped around each pulley 31 and changes direction from the center in the left-right direction toward both sides.

[0021] As shown in Figure 2, this training machine has a weight member 33 for adjusting the exercise intensity that is detachably attached to the movable part 3. The weight member 33 is a block having a predetermined mass and has a groove-shaped recess 34 formed therein. The weight member 33 is placed on the flat part of the upper surface of the base 22, and a fixing bracket 32 ​​is fitted into the recess 34 to hold the weight member 33 in place so that it does not slip and fall. Alternatively, the weight member 33 may be provided with a stopper that opens and closes the opening of the recess 34 to prevent the fixing bracket 32 ​​from coming out.

[0022] Here, the mass of the weight member 33 is variable. That is, by preparing blocks of different masses and swapping the blocks that are attached, or by preparing multiple blocks and stacking any number of blocks, the mass of the weight member 33 can be varied, and the exercise intensity can be arbitrarily adjusted according to the mass of the weight member 33.

[0023] By placing the weight member 33 on the base 22 of the handle 20 before starting the exercise, a downward force is applied to the handle 20. When the user holds the handle 20 and pulls it down, the block 12 of the weight unit 2 rises. At this time, the force from the weight member 33 acts, reducing the load on the user when pulling down the handle 20, thereby lowering the exercise intensity.

[0024] Next, when moving the handle 20 from bottom to top to return the block 12 of the weight 2, the user slightly reduces the strength of their arm. The weight of the weight 2 causes the handle 20 to move upward, stretching the muscles of the upper limb. At this time, the presence of the weight member 33 causes the handle 20 to start moving a little longer than if the weight member 33 were not present. In other words, by providing the weight member 33, a period of time is created in which the force on the weight 2 is balanced according to the mass of the weight member 33.

[0025] Thus, when the weight member 33 is attached to the moving part 3, even if the user applies the same force to the handle part 20, the speed at which the moving part 3 moves upward will be slower compared to when the weight member 33 is not attached. When the weight member 33 is attached, the acceleration of the moving part 3 is smaller, and the moving part 3 rises more slowly. As a result, the muscles are stretched slowly while continuously exerting force, which allows for effective muscle training.

[0026] Here, the intensity of the exercise can be adjusted by varying the mass of the weight member 33. The larger the mass of the weight member 33, the smaller the acceleration of the moving part 3, and the stronger the exercise intensity. The smaller the mass of the weight member 33, the larger the acceleration of the moving part 3, and the weaker the exercise intensity. Therefore, by placing weight members 33 of different masses on the handle part 20, the intensity of the exercise can be set. Then, by adjusting the balance between the weight member 33 and the weight part 2, an exercise intensity suitable for the user can be obtained.

[0027] <Second Embodiment> Figure 3 shows a training machine for the upper body according to the second embodiment. The moving part 3 of this training machine includes a swinging part 40 that allows the handle part 20 to swing horizontally, and a load transmission part 41 that connects the handle part 20 and the wire rope 30, and applies a load to the swinging of the handle part 20 using the weight part 2. The other configurations are the same as those of the training machine in the first embodiment.

[0028] The oscillating section 40 has a housing 42 that houses the load transmission section 41. As shown in Figure 4, the housing 42 is provided with a pair of upper and lower guide tubes 43 through which the guide column 25 is inserted, and the housing 42 is supported by the guide column 25 so as to be able to move up and down and rotate. The vertical shaft 44 fixed to the handle section 20 is rotatably supported by the housing 42 via a bearing 45 provided in the housing 42.

[0029] The load transmission unit 41 includes a rotation transmission unit 50 that transmits the rotational motion of the handle unit 20, and a crank mechanism unit 52 that converts the transmitted rotational motion into vertical motion of a sliding shaft 51 connected to a wire rope 30. The rotation transmission unit 50 consists of a sprocket 54 provided on the pivot shaft 44, a sprocket 56 provided on a support shaft 55 pivotally supported in the housing 42, a chain 57 wrapped around both sprockets 54 and 56, a bevel gear 58 provided on the support shaft 55, and a crown gear 59 that meshes with the bevel gear 58. The crown gear 59 is provided on a crankshaft 60 that is horizontally pivotally supported in the housing 42. The crank mechanism unit 52 has a crankshaft 60 and a connecting piece 62 that connects a projection 61 provided on the crankshaft 60 to the sliding shaft 51. The lower end of the connecting piece 62 is rotatably attached to the projection 61, and its upper end is rotatably attached to the lower end of the sliding shaft 51.

[0030] Then, as shown in Figure 5, the weight member 33 is detachably placed on the upper surface of the housing 42. A bearing fitting 63 that supports the sliding shaft 51 so that it can move up and down is fitted into the recess 34 of the weight member 33, so that the weight member 33 is held in place so that it does not slip off. The weight member 33 is the same as that of the first embodiment.

[0031] By placing the weight member 33 on the housing 42, a downward force is applied to the handle 20. When the user holds the handle 20 and pulls it down, the block 12 of the weight section 2 rises. At this time, the force from the weight member 33 is applied, reducing the load on the user when pulling down the handle 20, thereby lowering the exercise intensity.

[0032] Next, when the handle portion 20 is moved from bottom to top to return the block 12 of the weight portion 2, the presence of the weight member 33 causes a period of time during which the force is balanced relative to the weight portion 2 according to the mass of the weight member 33, and it takes a little longer for the handle portion 20 to start moving compared to when the weight member 33 is not present.

[0033] Thus, when the weight member 33 is attached to the moving part 3, even if the user applies the same force to the handle part 20, the speed at which the moving part 3 moves upward will be slower compared to when the weight member 33 is not attached. When the weight member 33 is attached, the acceleration of the moving part 3 is smaller, and the exercise intensity can be reduced. In the same way as above, the strength of the exercise can be adjusted, and an exercise intensity suitable for the user can be obtained.

[0034] Furthermore, this training machine is equipped with a means 70 for adjusting the intensity of the exercise. As shown in Figure 6, a tensioner is used to adjust the tension of the chain 57. The tensioner consists of an idler 71 that contacts the chain 57 and a bracket 72 that holds the idler 71, and the bracket 72 is slidably mounted in the housing 42. A bolt 73 is attached to the bracket 72, and an elongated hole 74 is formed in the housing 42 into which the lower part of the bolt 73 fits. As the bolt 73 moves along the elongated hole 74, the bracket 72 slides. In accordance with the sliding of the bracket 72, the idler 71 moves closer to and further away from the chain 57. The machine is equipped with a fixing means for sliding the bracket 72 and fixing it in the desired position. For example, by tightening the bolt 73, the bolt 73 contacts the bottom of the elongated hole 74, acting as a brake and fixing the bracket 72. Alternatively, the lower end of the bolt 73 protrudes from the housing 42, a nut is attached to the lower end, and the fixing and movement are performed by tightening or loosening the nut.

[0035] As shown in Figure 7, when the bracket 72 is brought closer to the chain 57, the idler 71 pushes against the chain 57, increasing the tension of the chain 57. With the chain 57 under increased tension, when the handle section 20 is lowered while rotating it downwards, and then raised upwards while returning the handle section 20 to its initial position, the time during which the load from the weight section 2 is balanced is increased, causing the handle section 20 to rotate slowly and accelerate as it moves upwards. This reduces the intensity of the movement.

[0036] As shown in Figure 8, when the bracket 72 is separated from the chain 57, the idler 71 returns the chain 57, and the tension of the chain 57 decreases. With the tension of the chain 57 reduced, the time during which it is balanced by the load from the weight section 2 is shortened, so the handle section 20 rotates while accelerating slightly faster. This brings the exercise intensity closer to the original intensity. In addition, although the adjustment means 70 above works in cooperation with the weight member 33 to adjust the strength of the exercise intensity, it is also possible to adjust the strength of the exercise intensity independently without using the weight member 33.

[0037] <Third Embodiment> Figure 9 shows a lower body training machine according to a third embodiment. The lower body training machine comprises a weight section 2 that is vertically movable on the main frame 1, a moving section 3 that uses the lower limbs to raise and lower the weight section 2, and a seating section 4.

[0038] The main frame 1 is formed from a gantry frame 10 and a lower frame 11 that supports the gantry frame 10. Multiple blocks 12 constituting the weight section 2 are stacked and arranged in the center of the gantry frame 10 in the left-right direction, and a predetermined number of blocks 12 set according to the user move up and down along the guide bar 13. A seating section 4 is provided on the rear side of the lower frame 11 that protrudes forward from the gantry frame 10, and a movable section 3 is provided in front of the seating section 4 so as to be movable in the front-rear direction.

[0039] The lower frame 11 is provided with a pair of front and rear support columns 80, and a circular shaft-shaped slide bar 81 is provided in two stages, upper and lower, between the two support columns 80. By arranging the pair of slide bars 81 vertically, the width occupied by the slide bars 81 in the left-right direction can be narrowed, making the training machine more compact. Of course, it is also possible to provide a pair of slide bars 81 on the left and right sides. The front side of the slide bar 81 is lower and the rear side is higher, and the slide bar 81 is installed so as to slope downwards toward the front. The movable part 3 has a slider part 82 that moves in the front-rear direction by the lower limbs, a pedal part 83 on which the user's feet are placed, and a connecting part 84 that connects the pedal part 83 and the weight part 2. The slider part 82 is slidably supported on the slide bar 81, and the pedal part 83 is positioned above the slider part 82. The slide bar 81 may also be configured so that the front side is higher and the rear side is lower.

[0040] The slider section 82 has a box-shaped housing 85, through which upper and lower slide bars 81 pass. Multiple rollers (not shown) are provided inside the housing 85, with the upper rollers pressing against the upper slide bar 81 and the lower rollers pressing against the lower slide bar 81, causing the housing 85 to slide in the front-back direction along the slide bars 81.

[0041] The pedal section 83 has a central footrest pedal 90 and left and right footrest plates 91, and the footrest pedal 90 and footrest plates 91 are mounted on a base 92 installed on the upper surface of the housing 85. A cylindrical holding member 93 is erected in the center of the base 92 in the left-right direction, and the concave footrest pedal 90 is attached to the holding member 93 so as to be rotatable around the front-rear axis and left-right axis. Flat footrest plates 91 are arranged on both the left and right sides of the holding member 93 and are attached to the base 92 via support angles 94.

[0042] The connecting section 84 is composed of a chain 100 as a cable and a plurality of sprockets 101 as guide wheels. One end of the chain 100 is fixed to a retaining member 93 on the base 92 of the pedal section 90, and the other end is connected to a fixing fitting provided on the block 12 at the top of the weight section 2. The chain 100 is arranged along the lower frame 11 below the seating section 4 via the plurality of sprockets 101, and is positioned from the bottom of the gate-shaped frame 10 toward the block 12 above. When the pedal section 83 moves in the front-rear direction, the block 12 of the weight section 2 moves up and down via the chain 100.

[0043] Then, as in the first and second embodiments described above, a weight member 33 is detachably attached to the pedal portion 83, as shown in Figure 10. The weight member 33 is placed inside the holding member 93, or on the left and right sides of the holding member 93 on the base 92, on the back of the footrest plate 91. The weight member 33 attached to the pedal portion 83 applies a force that moves the slider portion 82, which is supported by the inclined slide bar 81, forward, but the slider portion 82 does not move because the chain 100 is pulled by the weight portion 2.

[0044] The user sits on the seat 4, places both feet on the footrest plate 91, and then places one foot on the footrest pedal 90. When this foot is extended while twisting it from side to side, the slider 82 moves forward under the load of the weight 2. At this time, since the weight member 33 is attached to the pedal 83, the force from the weight member 33 acts to reduce the load on the pedal 83 when pushing it, thereby lowering the exercise intensity.

[0045] Next, when the user bends the extended leg and returns the block 12 of the weight section 2, the user slightly reduces the force of their leg. The weight of the weight section 2 pulls the pedal section 83 backward. At this time, because of the weight member 33, it takes a little longer for the pedal section 83 to start moving compared to when the weight member 33 is not present. In other words, by providing the weight member 33, a period of time is created in which the force on the weight section 2 is balanced according to the mass of the weight member 33.

[0046] Thus, when the weight member 33 is attached to the pedal 83, even if the user applies the same force to the pedal 83, the speed at which the pedal 83 moves backward becomes slower compared to when the weight member 33 is not attached, and the acceleration of the pedal 83 is smaller when the weight member 33 is attached. As the pedal 83 returns slowly, the muscles are stretched slowly while continuously exerting force, allowing for effective muscle training.

[0047] Furthermore, the intensity of the exercise can be adjusted by varying the mass of the weight member 33. The larger the mass of the weight member 33, the smaller the acceleration of the pedal section 83, and the stronger the exercise intensity. The smaller the mass of the weight member 33, the larger the acceleration of the pedal section 83, and the weaker the exercise intensity. In the same manner as above, the intensity of the exercise can be adjusted to obtain an exercise intensity suitable for the user.

[0048] <Fourth Embodiment> Figure 12 shows a training machine for the upper body according to the fourth embodiment. This training machine has a handle section 20 for the user to place their hands on, which serves as a handle section 20 for drawing out the movement of the entire shoulder, and the weight section 2 and the handle section 20 and connecting section 21 of the movable section 3 are provided on the left and right sides, respectively. The pad 26 of the handle section is attached to the upper part of a vertical axis (not shown), and the vertical axis is supported on the front of the base 22 so as to be able to rotate horizontally. The base 22 is supported on a guide column 25 so as to be able to move up and down and rotate horizontally. The other configurations are the same as the training machine of the first embodiment. The handle section is biased upward by the load of the weight section 2, and by pushing the handle section downward with the hand, the shoulder can be exercised, and it is also possible to exercise the left and right shoulders separately. The weight members 33 are placed on the base 22 as in the first embodiment. At this time, the mass of the left and right weight members 33 can be made different.

[0049] In the fourth embodiment, as an alternative configuration of the upper body training machine, the weight units 2, which were previously arranged separately on the left and right sides, are combined into one and placed in the center in the left-right direction, and the wire ropes 30 of the left and right connecting units 21 are connected to the weight unit 2. The other configurations are the same as the training machine of the fourth embodiment. Shoulder exercises can be performed by pushing the handholds downwards.

[0050] It should be noted that the present invention is not limited to the above embodiments, and many modifications and changes can be made to the above embodiments within the scope of the present invention. In the first and second embodiments, a recess 34 for fitting into the guide column 25 may be formed in the weight member 33, and the weight member 33 may be fitted into the guide column 25. Alternatively, two recesses 24 may be formed, and the weight member 33 may be supported by the fixing bracket 32 ​​and the guide column 25. Another form of detachably attaching the weight member 33 to the handle portion 20 is to attach the weight member 33 directly above the grip 23, as shown in Figure 11. A base 35 is integrally provided on the upper part of the grip 23, and the weight member 33 is placed on the base 35. A vertical shaft 24 is fitted into the recess 34 of the weight member 33, and the weight member 33 is held in place so as not to slip off the grip 23. [Explanation of symbols]
