Description

  The present invention relates to a training machine used for the purpose of maintaining and improving physical strength and health.

  Maintaining and improving physical fitness and health is necessary for daily life and various sports activities. Various training machines have been used for various purposes. It has been broken. A training machine used when an athlete or the like attempts to improve physical strength is configured to apply a heavy load to a trainee. A training machine used when an elderly person tries to maintain and improve physical strength and health for the purpose of care prevention or the like is configured so that a light load corresponding to the physical strength of the trainee can be applied to the trainee.

  As an example of a training machine, a sliding walking machine has been proposed (see Patent Document 1). As shown in FIG. 26, the sliding walking machine 210 includes a bottom seat frame 214 having two arc-shaped side frames 212 parallel to the upper portion, a bottom plate 216, a smooth surface plate 218, an auxiliary handle 220, a protective side strip 224, a shoe body. 226 and a smooth shoe cover 228. The bottom plate 216 is sandwiched between the bottom seat frame 214 and the smooth surface plate 218, the auxiliary handle 220 can be fixed to any one side of the bottom seat frame 214, and the smooth surface plate 218 is fixed to the upper surface of the bottom seat frame 214. A pair of smooth shoe covers 228 fitted to the outside lower side of the body 226 are combined on the smooth plate 218 so as to be arbitrarily slidable without any direction restriction.

  As shown in FIG. 27, when the trainee performs a walking exercise using the sliding walking machine 210, the auxiliary handle 220 is fixed to the front end of the bottom seat frame 214. The trainee grasps the grip 222 at the upper end of the auxiliary handle 220 and puts on the shoe body 226 having the smooth shoe cover 228 and stands on the smooth plate 218. Then, the trainee performs a walking motion by sliding both feet on the smooth plate 218 in the front-rear direction of the body while holding the grip 222.

  When the trainee performs a jogging exercise, the auxiliary handle 220 is fixed to the front end of the bottom seat frame 214, and the front end of the bottom seat frame 214 is raised to tilt the bottom seat frame 214 appropriately. The trainee grips the grip 222, wears the shoe body 226 having the smooth shoe cover 228, stands on the smooth plate 218, and slides both feet in the front-rear direction of the body to perform a jogging operation.

  When the trainee moves his / her foot in the left / right direction of the body to perform a sliding motion, the auxiliary handle 220 is fixed to the side of the bottom seat frame 214. The trainee grips the grip 222, wears the shoe body 226 having the smooth shoe cover 228, stands on the smooth plate 218, and performs a reciprocating motion that opens and closes while sliding both feet in the left-right direction of the body. It is also possible to slide left and right of the body with both feet aligned.

In other words, the trainee can slide his / her feet on the smooth surface plate 218 in any direction, front, back, left and right of the body, and can perform various exercises using the sliding walking machine 210. In the following description, the action of sliding both feet in the front-rear direction of the body, including walking action and jogging action, is called the front-rear direction sliding action, and the action of sliding both legs in the left-right direction of the body This is called directional sliding motion.
Registered Utility Model No. 3044007

  In general, in the sliding motion in the front-rear direction, when the foot is slid toward the front of the body, if the sliding amount is large, the movement of the body increases and a heavy load is applied to the body. However, in this sliding walking machine 210, the auxiliary handle 220 is fixed to the front side of the trainee's body, which interferes with the trainee. The trainee is obstructed by the auxiliary handle 220 and cannot slide his / her foot largely forward of the body, and cannot apply a heavy load to the body by the forward / backward sliding motion. Therefore, when an athlete or the like has to exercise while applying a heavy load, the sliding walking machine 210 cannot perform a necessary exercise.

  The present invention solves the above problems, and an object of the present invention is to provide a training machine that allows a trainee to easily perform exercises with various weight loads.

The present invention adopts the following configuration in order to solve the problem.
That is, the training machine according to the present invention is provided with a smooth surface on which the trainer rides by bending back and forth, and a handrail that stretches in the front-rear direction on both sides of the smooth surface and holds the trainer on the smooth surface. Yes.
The smooth surface is constituted by a member having a smooth surface. For example, the smooth surface can be formed of a polished resin such as stainless steel or polycarbonate, or a non-ferrous metal such as copper. The shape of the smooth surface may be a curved surface having a certain curvature, or may be a curved surface where the curvature changes. Alternatively, the front and back warped portions may be curved surfaces, and a smooth surface may be configured by sandwiching a flat surface between the front and rear curved surfaces.

  When the trainee performs a sliding motion in the front-rear direction, the trainee rides on the smooth surface, grabs the handrail on both sides of the smooth surface with both hands, and stands facing the front of the warped smooth surface. When the trainee steps one foot forward, the stepped foot slides back on the smooth surface and returns to its original position. The same applies when the other leg is stepped forward of the body. The trainee performs a back-and-forth sliding motion by alternately stepping left and right feet forward of the body.

  In addition, the trainee can perform a leg-opening operation in the front-rear direction by sliding one foot forward of the body and simultaneously sliding the other foot rearward as the front-back sliding operation. By performing a leg opening operation in the front-rear direction, the trainee can widen the range of motion of the hip joint. Also. Training of the psoas muscle, which is indispensable for improving ADL (daily life movement) ability. Further, the trainee can slide in the front-rear direction by sliding the body in the front-rear direction while keeping both feet together.

  The handrail that the trainee grabs extends on both sides of the smooth surface in the longitudinal direction of the smooth surface. If the trainer stands with both hands on both handrails, the handrail is not positioned in front of the trainer's body. For this reason, even if the trainee steps his / her foot forward in front of the body, the handrail does not interfere with the movement of the foot. Therefore, the trainee can easily perform the forward / backward sliding motion with a heavy load. Also, the trainee can easily adjust the weight of the load by appropriately changing the amount of stepping and sliding.

  When the trainee performs a sliding motion in the left-right direction, the trainee rides on the smooth surface, grabs with one handrail with both hands, and stands facing the grab rail. Then, the trainee can perform a sliding motion in the left-right direction by opening and closing both feet while sliding both feet in the left-right direction of the body. It is also possible to slide left and right of the body with both feet aligned and attached.

  The trainee can easily perform the front-rear direction sliding operation and the left-right direction sliding operation on the smooth surface by wearing footwear having a slippery bottom surface on the smooth surface or wearing roller skates. The footwear having a slippery bottom surface is, for example, footwear having a bottom surface made of a material having a small coefficient of friction with the smooth surface. Also, the trainee can easily perform the sliding motion in the front-rear direction also by placing on the skateboard on the smooth surface.

Here, the training machine according to the present invention preferably has a curvature adjusting mechanism for changing the curvature of the curved portion of the smooth surface.
If it is such a structure, if the curvature of the curved part of a smooth surface is adjusted with a curvature adjustment mechanism, the trainee can adjust the weight of the load in the front-back direction sliding operation | movement or the left-right direction sliding operation. For example, if the radius of curvature of the curved portion of the smooth surface is increased, the degree of curvature of the smooth surface becomes gentle, and the trainee can perform a forward / backward sliding motion and a lateral sliding motion while applying a light load to the body. Also, if the radius of curvature of the curved portion of the smooth surface is reduced, the degree of curvature of the smooth surface becomes tight, and the trainee can perform a forward / backward sliding motion and a lateral sliding motion while applying a heavy load to the body.

Moreover, the training machine according to the present invention preferably has a handrail height adjusting mechanism for adjusting the height of the handrail.
If it is such a structure, if the height of the handrail is adjusted by the handrail height adjusting mechanism, the trainee can hold the handrail in a posture suitable for him. For example, if the height of the handrail is about the height of the trainee's flank, the trainee can perform a forward / backward sliding motion and a lateral sliding motion while holding the handrail in an easy posture. If the height of the handrail is increased, the trainee can perform a forward / backward sliding motion and a lateral sliding motion while holding the handrail with both hands and hanging.

In addition, the training machine according to the present invention preferably has a handrail interval adjusting mechanism that adjusts the interval between the pair of handrails. If it is such a structure, if the space | interval of a pair of handrails is adjusted with a handrail space | interval adjustment mechanism, the trainee can hold onto the handrail in a posture more suitable for his / her physique.
The training machine according to the present invention preferably includes a handrail posture adjustment mechanism that changes one of the pair of handrails or both of the handrails to a standing posture and a lying posture. In such a configuration, if the handrail posture is adjusted to the lying posture by the handrail posture adjustment mechanism, when the exercise moves the upper body in the left-right direction of the training machine, for example, the handrail is retracted to a position where it does not interfere with the exercise. be able to.

  In addition, the training machine according to the present invention preferably includes a connecting rod that connects the pair of handrails and holds the trainee. If it is such composition, a trainee can perform a horizontal bar movement on a smooth surface by grasping to this connecting bar. For example, the trainee can practice the upward movement of the horizontal bar using the curved smooth surface shape.

  Since the training machine is as described above, the trainee can easily perform exercises with loads of various weights.

As shown in FIGS. 1 and 2, the training machine 10 includes a frame 18, a smooth plate 11, and a pair of handrails 13.
The frame 18 includes left and right side plates 19a and 19b, a front plate 20f, a rear plate 20r, and a bottom plate 21. The smooth surface plate 11 is a stainless steel plate installed on the upper portion of the frame 18. The surface of the smooth surface plate 11 is polished to form a smooth surface 12. The smooth surface plate 11 is supported on a plurality of lateral beams 23 spanned between the side plate 19a and the side plate 19b, and the left and right sides thereof are screwed to the side plates 19a and 19b, respectively. The smooth surface 12 is curved and warped in the front-rear direction of the training machine 10, and the curvature of the curved portion of the smooth surface 12 is warped up so that the muscles such as the trunk can be efficiently trained. Is at a predetermined size that is at least higher than the knee height of the trainee.

  A handrail support mechanism 26 is formed on the front plate 20f side portion and the rear plate 20r side portion of the frame 18, respectively. Each handrail support mechanism 26 includes guide shafts 27a and 27b and guide blocks 28a and 28b. Guide shafts 27a and 27b are sandwiched and fixed between the side plate 19a and the side plate 19b, respectively. The guide shafts 27a and 27b are parallel to each other and are lined up and down. Guide shafts 27 a and 27 b penetrate the guide blocks 28 a and 28 b in the left-right direction of the training machine 10. The guide blocks 28a, 28b are configured to be slidable in the left-right direction of the training machine 10 along the guide shafts 27a, 27b. A leg hole 29 for inserting the leg portion 15 of the handrail 13 is formed in the upper part of each guide block 28a, 28b.

  Each handrail 13 has a “U” shape. The central portion 14 of the “U” shape is covered with rubber or resin so that the trainee can hold the handrail 13 firmly. A plurality of pin holes 31 are formed in the “U” -shaped leg portion 15 of the handrail 13, and the pin holes 31 are arranged in the axial direction of the leg portion 15. The leg portions 15 of the handrails 13 are inserted into the leg holes 29 of the guide blocks 28 a and 28 b of the handrail support mechanism 26. A central portion 14 of each handrail 13 is located on both sides of the smooth surface 12 and extends in the front-rear direction of the training machine 10.

A plurality of pin holes 32 are formed side by side in the left-right direction of the training machine 10 in the front plate 20 f and the rear plate 20 r of the frame 18. By selecting an appropriate pin hole 31 and pin hole 32 and inserting the pin 34a, the height of the central portion 14 of the handrail 13 and the interval between the handrails 13 on both sides of the smooth surface 12 can be adjusted.
The front plate 20f is formed with two vertically long windows 90a. The window 90 a is located below the pin hole 32. A scale continuous in the vertical direction is formed on the side of the window 90a, and this scale forms a handrail height scale 92a. A pin forming the handrail height indicator 34b is inserted into the pin hole 31 at the lowermost end of the leg portion 15 of the handrail 13, and the head of the handrail height indicator 34b is visible from the window 90a. The height of the handrail 13 can be known by reading the height of the head of the handrail height indicator 34b using the handrail height scale 92a.

  A scale continuous in the left-right direction is formed on the upper edge of the front plate 20f, and this scale forms a handrail interval scale 93a. Each scale of the handrail interval scale 93a corresponds to the position of each pin hole 32 arranged in the left-right direction. The pin 34a is inserted into the pin hole 31 and the pin hole 32, and the position of the leg portion 15 of the handrail 13 is read using the handrail interval scale 93a so that the interval between the handrails 13 can be known. Yes.

A data display device 100 is arranged on the front plate 20 f side portion of the frame 18. The data display device 100 has a clock function and a timer function, and is configured to be able to display the time that the trainee exercised using the training machine 10.
Sensors 103 a and 103 b of the pedometer 102 are installed on the left and right sides of the frame 18. The sensor 103a is a light projector of a photoelectric sensor, and the sensor 103b is a light receiver of the photoelectric sensor. The sensor 103b can receive light emitted from the sensor 103a. The number-of-steps measuring device 102 measures the number of times that the light of the sensor 103b is blocked by the trainee's foot on the smooth surface 12, and the data display device 100 uses the number of times the trainee has reciprocated on the smooth surface 12 as the number of steps. It is configured so that it can be displayed.
Footwear 36 for a trainee to wear is prepared. On the bottom surface of the footwear 36, a cloth having a small coefficient of friction with the smooth surface 12 is applied.

Next, the operation will be described.
First, a case where the trainee performs a longitudinal sliding motion will be described.
The trainee selects an appropriate pin hole 31 and pin hole 32, inserts the pin 34a, and adjusts the height of each handrail 13 and the interval between the handrails 13 according to his / her physique. Then, the pin of the handrail height indicator 34 b is inserted into the pin hole 31 at the lowermost end of the leg portion 15 of the handrail 13. After adjusting the height and interval of the handrail 13, as shown in FIG. 3, the trainee puts on the footwear 36 and holds it with both hands on the handrail 13 on both sides of the smooth surface 12, facing the front of the training machine 10, and on the smooth surface 12. Stand in.

  The trainee steps on the left and right feet alternately toward the front of the body while being held by the handrails 13 on both sides of the smooth surface 12. When the trainee steps on the right foot forward and puts the right foot on the smooth surface 12, the bottom surface of the footwear 36 worn on the right foot slides backward on the smooth surface 12, and the right foot is the original on the smooth surface 12. Return to position. The same applies when the left foot is stepped forward. The trainee can perform a back-and-forth sliding motion by stepping the left and right feet alternately forward of the body.

  The trainee can slide one leg forward of the body and simultaneously slide the other leg backward of the body to perform a leg opening operation in the front-rear direction of the body and perform a front-back sliding operation. The trainee can easily perform the leg opening operation in the front-rear direction of the body by sliding the foot in the front-rear direction of the body. This leg-opening action is a flexible movement that extends the range of motion of the trainee's hip joint. In addition, it will be an exercise to train the psoas muscle.

  In addition, the trainee can slide in the front-rear direction by sliding the body in the front-rear direction while keeping both feet together. Increasing the amount by which the trainee steps on the front of the body, or increasing the amount by which the trainer can slide the foot in front of the body, increases the load on the body. In addition, if the amount of the trainer stepping forward or sliding the body forward is reduced, the load acting on the body is reduced.

The handrail 13 is located on both sides of the smooth surface 12 and is not located in front of the body of the trainee who performs the longitudinal sliding motion. Therefore, the handrail 13 does not interfere with the forward / backward sliding motion, and the trainee can easily change the amount of stepping forward or sliding forward of the body, and the weight of the load acting on the body is easy. Can be adjusted.
In FIG. 3, the height of the handrail 13 is about the height of the trainee's flank. If the handrail 13 is about the height of the flank, the trainee can hold it with both hands on the handrail 13 on both sides of the smooth surface 12 in an easy posture, and exclusively apply the load caused by the sliding motion in the longitudinal direction to the lower limbs. Can do. The trainee can read the height of the handrail height indicator 34b using the handrail height scale 92a and easily know the height of the handrail 13, so that the height of the handrail 13 can be easily adjusted. Can do.

  As shown in FIG. 4, if the height of the handrail 13 is increased by changing the position of the pin hole 31 through which the pin 34 a is inserted, the trainee can hang by holding the handrail 13 on both sides of the smooth surface 12 with both hands. it can. The trainee can hang from the handrail 13 and swing the entire body in the front-rear direction of the body to perform a front-back sliding operation. In this case, the trainee exercises using the entire body, and can easily exercise the whole body.

  The trainee can change the position of the pin hole 32 through which the pin 34a is inserted, adjust the distance between the handrails 13 on both sides, and adjust the weight of the load acting on the body of the trainee. Since the trainee can read the position of the leg portion 15 of the handrail 13 from the handrail interval scale 93a and easily know the interval between the handrails 13, the interval between the handrails 13 can be easily adjusted.

  When the trainee performs a back-and-forth sliding motion, the trainee's foot prevents the sensor 103b from receiving light. The pedometer 102 measures the number of times that the sensor 103b is prevented from receiving light, and displays on the data display device 100 how many times the trainee has reciprocated his / her foot on the smooth surface 12 as the number of steps. In addition, the time that the trainee performed the sliding operation in the front-rear direction is also displayed on the data display device 100. Therefore, the trainee can easily know how much he / she performed the forward / backward sliding motion, and can easily control the training amount. If the footwear 36 is a roller skate, the trainee can slide his / her foot very smoothly on the smooth surface 12, and can more easily perform the leg opening operation in the front-rear direction.

  Also, as shown in FIG. 5, an iron rod 37 that is a detachable connecting rod is bridged between the handrails 13 on both sides of the smooth surface 12, and both ends of the iron rod 37 are fixed to the handrail 13 by clamps 38. The trainee can hold the iron bar 37 and exercise the iron bar on the smooth surface 12. For example, the trainee can practice the upward movement of the horizontal bar using the curved shape of the smooth surface 12.

Next, a case where the trainee performs a left-right sliding operation will be described.
As in the case of performing the forward / backward sliding operation, the trainee adjusts the height of each handrail 13 and the interval between the handrails 13 according to his / her physique. Then, the trainee puts on the footwear 36 and is grasped with both hands on the handrail 13 on one side of the smooth surface 12, faces the side of the training machine 10, and stands on the smooth surface 12.

  The trainee slides both feet toward the left and right sides of the body on the smooth surface 12 while being held by one handrail 13 and opens both feet in the left and right directions of the body. When the trainee opens both feet on the smooth surface 12, the bottom surface of the footwear 36 worn on both feet slides on the smooth surface 12, both feet return to their original positions on the smooth surface 12, and both feet close. Therefore, the trainee can perform a sliding motion in the left-right direction. In addition, the trainee can slide left and right of the body with both feet aligned and perform a left-right sliding motion.

  Increasing the amount by which the trainee slides his / her foot in the left / right direction of the body increases the load on the body. If the amount by which the trainee slides his / her foot in the left / right direction of the body is reduced, the load acting on the body is reduced. The trainee is grasped by one hand on the handrail 13 in front of the body, and the handrail 13 does not interfere with the left-right sliding operation. The trainee can easily change the amount of sliding of the foot, and can easily adjust the weight of the load acting on the body. If the height of the handrail 13 is about the height of the trainee's flank, the trainee can hold the handrail 13 in an easy posture, and can apply the load caused by the lateral sliding motion exclusively to the lower limbs.

Since the training machine 10 is as described above, the trainee can exercise while applying a load having an appropriate weight according to his / her purpose. Athletes can actively improve their physical strength while applying heavy loads, and elderly people aiming at care prevention etc. aim to maintain and improve physical strength and health while applying light loads according to physical strength be able to.

The trainee turns the curvature adjustment handle 51 of the curvature adjustment mechanism 40f in one direction, rotates the screw shaft 53 in one direction, and moves the nut 54 screwed to the screw shaft 53 toward the rear of the training machine 10. When the nut 54 moves toward the rear of the training machine 10, the arm 55 also moves toward the rear of the training machine 10, and the tip portion of the plate member 42 c connected to the arm 55 is pushed toward the rear of the training machine 10. . The curvature adjusting plate 41 is greatly curved, and the smooth surface plate 11f on the curvature adjusting plate 41 is also greatly curved. Therefore, the radius of curvature of the smooth surface 12 of the smooth plate 11f is reduced.

  When the curvature adjusting plate 41 is greatly bent, the smooth surface plate 11f slides on the curvature adjusting mechanism 40f, and the tip of the smooth surface plate 11f tries to push up the pressing plate 57. The front end of the smooth surface plate 11f is pressed by the pressing plate 57, and the rear end of the smooth surface plate 11f is screwed to the cross beam 23, so that the central portion of the smooth surface plate 11f is separated from the curvature adjusting plate 41 and is likely to float. To do. When the central portion of the smooth surface plate 11f is lifted away from the curvature adjusting plate 41, the ring 45 loosely fitted to the shaft 48d is moved on the shaft 48d, and a gap between the smooth surface plate 11f and the curvature adjusting plate 41 is formed. Adjust smaller. When the gap between the smooth surface plate 11f and the curvature adjusting plate 41 is minimized, the position of the ring 45 on the shaft 48d is fixed by the stopper 46.

  When the trainee turns the curvature adjusting handle 51 in the opposite direction, the nut 54 moves toward the front of the training machine 10 and the arm 55 also moves toward the front of the training machine 10. The distal end portion of the plate member 42c connected to the arm 55 is pulled toward the front of the training machine 10, the curvature of the curvature adjusting plate 41 is reduced, and the curvature radius of the smooth surface 12 of the smooth surface plate 11f on the curvature adjusting plate 41 is reduced. Becomes larger.

  When the trainee turns the curvature adjustment handle 51, the curvature indicator 96 moves together with the nut 54. The trainee can know the degree of curvature of the curvature adjusting plate 41 by reading the position of the tip of the indicator needle of the curvature indicator 96 with the curvature scale 97 and know the curvature of the smooth surface 12 of the smooth surface plate 11f. it can. Therefore, the trainee can easily adjust the curvature of the smooth surface 12 of the smooth surface plate 11f by referring to the position of the pointing needle of the curvature indicator 96.

Adjustment of the curvature of the smooth surface 12 of the smooth surface plate 11r is performed similarly to the adjustment of the curvature of the smooth surface 12 of the smooth surface plate 11f. The trainee may match the curvature of the smooth surface 12 of the smooth surface plate 11r with the curvature of the smooth surface 12 of the smooth surface plate 11f, or the curvature of the smooth surface 12 of the smooth surface plate 11r may be the same as that of the smooth surface 12 of the smooth surface plate 11f. The size can be different from the curvature.
In the first modification, the smooth plate 11f is placed on the curvature adjusting mechanism 40f, and the smooth plate 11r is placed on the curvature adjusting mechanism 40r. Instead, one smooth surface plate 11 may be placed on the curvature adjusting mechanism 40f and the curvature adjusting mechanism 40r, and the center portion in the front-rear direction of the smooth surface plate 11 may be screwed into the screw hole 24 of the cross beam 23.

In FIG. 8, the illustration of the side plate is omitted, and the illustration of the smooth surface plate is omitted in FIG.

  An indicator needle constituting a curvature indicator 96a is attached to the end of the shaft 48g on the side plate 19b side. The curvature indicator 96a is visible from the outside of the frame 18 through a window (not shown) on the side surface of the side plate 19b. A curvature scale 97a is provided at the edge of the window where the curvature indicator 96a can be visually recognized, and the position of the curvature indicator 96a can be read by the curvature scale 97a.

Support frames 107 b and 107 c are installed on the bottom plate 21. The screw shaft 53b extends in the front-rear direction of the training machine 10, and the tip of the screw shaft 53b is pivotally supported by the support frame 107b. An intermediate portion of the screw shaft 53b is pivotally supported by the support frame 107c. A rear end portion of the screw shaft 53b penetrates the rear plate 20r and protrudes to the outside of the frame 18. A curvature adjusting handle 51b is attached to the rear end of the screw shaft 53b.

  The guide shaft 49b extends in the front-rear direction of the training machine 10, and the guide shaft 49b is supported at both ends by a support frame 107b and a support frame 107c. The screw shaft 53b passes through the guide block 56b between the support frame 107b and the support frame 107c, and the guide block 56b is screwed with the screw shaft 53b. The guide shaft 49b passes through the guide block 56b, and the guide block 56b is slidable along the guide shaft 49b.

  The guide block 56b is connected to the arm 55b. The arm 55 b has a shaft 48 h extending in the left-right direction of the training machine 10. A plurality of rollers 105b are fixed to the shaft 48h, and the intervals between adjacent rollers 105b are substantially equal. The height from the bottom plate 21 to the roller 105 b is approximately one third of the height of the frame 18.

  An indicator needle forming a curvature indicator 96b is attached to the end of the shaft 48h on the side plate 19b side. The curvature indicator 96b is visible from the outside of the frame 18 through a window (not shown) on the side surface of the side plate 19b. A curvature scale 97b is provided at the edge of the window where the curvature indicator 96b can be visually recognized, and the position of the curvature indicator 96b can be read by the curvature scale 97b.

  The tip of one smooth surface plate 11r is screwed into the screw hole 24 of the cross beam 23, and the smooth surface plate 11r is supported on the rollers 105a and 105b of the curvature adjusting mechanism 40a on the rear plate 20r side. Similarly, the rear end of one smooth surface plate 11f is screwed into the screw hole 24 of the cross beam 23, and the smooth surface plate 11f is supported on the rollers 105a and 105b of the curvature adjusting mechanism 40a on the front plate 20f side. Yes.

  Each of the smooth surface plates 11r and 11f is previously curved with a predetermined curvature. In the curvature adjusting mechanism 40a on the rear plate 20r side, the largest radius of curvature that can be formed by the screw hole 24 of the cross beam 23, the roller 105a, and the roller 105b is given in advance as the curvature of the smooth surface plate 11r. Similarly, also in the curvature adjusting mechanism 40a on the front plate 20f side, the largest radius of curvature that can be formed by the screw hole 24 of the cross beam 23, the roller 105a, and the roller 105b is given in advance as the curvature of the smooth plate 11f. Other configurations of the second modification are the same as those of the first modification.

Next, adjustment of the curvature of the smooth surface plate 11r will be described.
The trainee turns the curvature adjustment handle 51a of the curvature adjustment mechanism 40a on the rear plate 20r side in one direction, rotates the screw shaft 53a in one direction, and moves the guide block 56a screwed to the screw shaft 53a to the front of the training machine 10. Move towards. When the guide block 56a moves toward the front of the training machine 10, the arm 55a, the shaft 48g, and the roller 105a move toward the front of the training machine 10. Then, the roller 105a pushes the smooth plate 11r from the rear plate 20r side.

  When the trainee turns the curvature adjustment handle 51a of the curvature adjustment mechanism 40a on the rear plate 20r side, he also turns the curvature adjustment handle 51b of the curvature adjustment mechanism 40a on the rear plate 20r side. The trainee rotates the screw shaft 53 b and moves the guide block 56 b screwed to the screw shaft 53 b toward the front of the training machine 10. If the guide block 56b moves, the arm 55b, the shaft 48h, and the roller 105b also move together. Then, the roller 105b pushes the smooth surface plate 11r from the rear plate 20r side.

  The trainee turns the curvature adjusting handles 51a and 51b, respectively, and forms an appropriate large curvature radius by the screw hole 24 of the cross beam 23, the roller 105a, and the roller 105b. The smooth surface plate 11r has a front end fixed by a cross beam 23, and an intermediate portion is pressed by rollers 105a and 105b. As a result, the curvature of the smooth surface plate 11r matches the curvature formed by the screw hole 24 of the cross beam 23, the roller 105a, and the roller 105b.

  If the trainee turns the curvature adjustment handles 51a and 51b so that the curvature radii formed by the screw holes 24 of the cross beam 23, the rollers 105a and 105b become small, the curvature radius of the smooth surface plate 11r becomes small. If the trainee turns the curvature adjusting handles 51a and 51b in the direction in which the curvature radius formed by the screw hole 24 of the cross beam 23, the rollers 105a and 105b increases, the smooth plate 11r returns to the original curvature, and the smooth plate The radius of curvature of 11r increases.

  The positions of the rollers 105a and 105b are known from the positions of the curvature indicators 96a and 96b, respectively. If the positions of the rollers 105a and 105b are known by the positions of the curvature indicators 96a and 96b, the curvature of the smooth surface plate 11r can also be known. Therefore, the trainee can easily adjust the curvature of the smooth surface plate 11r while checking the positions of the curvature indicators 96a and 96b.

  Similarly to the adjustment of the curvature of the smooth surface plate 11r, the curvature of the smooth surface plate 11f can be adjusted. Comparing the curvature adjustment mechanism 40a of the second modification with the curvature adjustment mechanisms 40f, 40r of the first modification, the structure of the curvature adjustment mechanism 40a of the second modification is simplified, and the operation is easy. Further, the curvature adjusting mechanism 40a of the second modification can be lighter in weight than the curvature adjusting mechanisms 40f and 40r of the first modification, and the manufacturing cost can be reduced. In the second modification, the smooth surface plate 11f and the smooth surface plate 11r may be a single smooth surface plate 11, and the central portion in the front-rear direction of the smooth surface plate 11 may be screwed into the screw hole 24 of the cross beam 23.

  It is also possible to adjust the curvature of the smooth surface of the smooth surface plate of the training machine as shown in the modified example 3 of FIGS. FIG. 10 is a partial right side view of the curvature adjustment mechanism of the training machine according to the third modification, and FIG. 11 is a partial top view of the curvature adjustment mechanism of the training machine according to the third modification. In addition, illustration of a side plate is abbreviate | omitted in FIG. 10, and illustration of a smooth surface board is abbreviate | omitted in FIG.

  As in the second modification, a single cross beam 23 is installed at the center in the front-rear direction of the training machine 10. Two curvature adjusting mechanisms 40 b are installed on the bottom plate 21. One curvature adjusting mechanism 40b is located on the front plate 20f side of the frame 18, and the other curvature adjusting mechanism 40b is located on the rear plate 20r side of the frame 18, and both are configured symmetrically across the cross beam 23. ing.

The curvature adjustment mechanism 40b of Modification 3 includes curvature adjustment handle mechanisms 50a and 50b, but differs in configuration from the curvature adjustment mechanism 40a of Modification 2 in the following points.
That is, the timing pulley 109a is attached to the tip of the screw shaft 53a of the curvature adjusting handle mechanism 50a. Further, the rear end of the screw shaft 53b of the curvature adjusting handle mechanism 50b does not reach the rear plate 20r, and a timing pulley 109b is attached to the rear end of the screw shaft 53b. A timing belt 110 is suspended between the timing pulley 109a and the timing pulley 109b. When the curvature adjusting handle 51a is turned, the screw shafts 53a and 53b rotate together.

  The radii of the timing pulleys 109a and 109b and the intervals between the screw threads of the screw shafts 53a and 53b are configured such that the ratio of the movement amounts of the guide blocks 56a and 56b is a predetermined ratio. Only the curvature scale 97a and the curvature indicator 96a are attached, and no curvature indicator is attached to the shaft 48h. Other configurations of Modification 3 are the same as those of Modification 2.

  When the trainee adjusts the curvature of the smooth surface plate 11r, it is only necessary to turn the curvature adjustment handle 51a. That is, the positions of the screw holes 24 of the cross beam 23, the rollers 105a and 105b are determined, and the curvature of the smooth surface plate 11r can be adjusted by these positions. Further, since the trainee only has to adjust the curvature of the smooth surface plate 11r while referring only to the reading of the curvature indicator 96a, the adjustment work is easier than in the case of the second modification.

  Similar to the adjustment of the curvature of the smooth surface plate 11r, the trainee can adjust the curvature of the smooth surface plate 11f. Comparing the curvature adjustment mechanism 40b of the modification 3 and the curvature adjustment mechanisms 40f and 40r of the modification 1, the structure of the curvature adjustment mechanism 40b of the modification 3 is simplified and the operation is easy. Further, the curvature adjustment mechanism 40b of the third modification can be lighter and lighter than the curvature adjustment mechanisms 40f and 40r of the first modification, and the manufacturing cost can be reduced.

  Comparing the curvature adjustment mechanism 40b of the modification 3 and the curvature adjustment mechanism 40a of the modification 2, only the curvature adjustment handle 51a needs to be operated in the modification 3, but the curvature adjustment handles 51a and 51b are operated in the modification 2. Must. Therefore, the curvature adjusting mechanism 40b of the third modification is easier to operate. In the third modification, the smooth surface plate 11f and the smooth surface plate 11r may be a single smooth surface plate 11, and the center portion in the front-rear direction of the smooth surface plate 11 may be screwed to the screw hole 24 of the cross beam 23.

  It is also possible to adjust the curvature of the smooth surface of the smooth surface plate of the training machine as shown in Modification 4 of FIGS. FIG. 12 is a partial right side view of the curvature adjustment mechanism of the training machine according to Modification Example 4. FIG. 13 is a partial top view of the curvature adjustment mechanism of the training machine according to Modification Example 4. In addition, illustration of a side plate is abbreviate | omitted in FIG. 12, and illustration of a smooth surface board is abbreviate | omitted in FIG.

Two curvature adjusting mechanisms 40 c are installed on the bottom plate 21. One curvature adjustment mechanism 40c is located on the front plate 20f side of the frame 18, and the other curvature adjustment mechanism 40c is located on the rear plate 20r side of the frame 18, and both are configured symmetrically across the cross beam 23. ing.
The configuration of the curvature adjusting mechanism 40c on the rear plate 20r side will be described.
The curvature adjustment mechanism 40c includes a curvature adjustment handle mechanism 50c, an arm 55c, rollers 105c and 105d, a curvature indicator 96c, and a curvature scale 97c. The curvature adjustment handle mechanism 50c includes a curvature adjustment handle 51c, a screw shaft 53c, a guide block 56c, and a support frame 107d.

  The support frame 107d is installed on the rear plate 20r inside the frame 18. The screw shaft 53c extends in the front-rear direction of the training machine 10, and the tip of the screw shaft 53c is pivotally supported by the support frame 107d. A rear end portion of the screw shaft 53c penetrates the rear plate 20r and protrudes to the outside of the frame 18. A curvature adjusting handle 51c is attached to the rear end of the screw shaft 53c. The guide block 56c has a screw hole, and a screw shaft 53c is screwed into and penetrates the screw hole.

  The lower end of the arm 55c is pivotally supported by a shaft 48i provided on the bottom plate 21. The shaft 48 i extends in the left-right direction of the training machine 10. The arm 55c has a shaft 48j extending in the left-right direction of the training machine 10 at the tip. A plurality of rollers 105c are fixed to the shaft 48j, and the intervals between adjacent rollers 105c are substantially equal. The height from the bottom plate 21 to the roller 105 c is slightly lower than the height of the frame 18.

  The arm 55c has a shaft 48k extending in the left-right direction of the training machine 10 at a position of about a quarter from the lower end to the tip of the arm 55c. A plurality of rollers 105d are fixed to the shaft 48k, and the intervals between adjacent rollers 105d are substantially equal. A guide rail 113 of the linear motion guide device 112 is attached to the rear plate 20r side of the tip side portion of the arm 55c. The guide rail 113 extends in the vertical direction. The slider 114 of the linear motion guide device 112 is connected to the guide block 56c through a hinge 116.

  An indicator needle constituting a curvature indicator 96c is attached to the end of the shaft 48j on the side plate 19b side. The curvature indicator 96c is visible from the outside of the frame 18 through a window (not shown) on the side surface of the side plate 19b. A curvature scale 97c is installed at the edge of the window where the curvature indicator 96c can be visually recognized, and the position of the curvature indicator 96c can be read by the curvature scale 97c.

  The tip of one smooth surface plate 11r is screwed into the screw hole 24 of the cross beam 23, and the smooth surface plate 11r is supported on the rollers 105c and 105d of the curvature adjusting mechanism 40c on the rear plate 20r side. Similarly, the rear end of one smooth surface plate 11f is screwed into the screw hole 24 of the cross beam 23, and the smooth surface plate 11f is supported on the rollers 105c and 105d of the curvature adjusting mechanism 40c on the front plate 20f side.

  Each of the smooth surface plates 11r and 11f is previously curved with a predetermined curvature. In the curvature adjusting mechanism 40c on the rear plate 20r side, the largest radius of curvature that can be formed by the screw hole 24 of the cross beam 23, the roller 105c, and the roller 105d is given in advance as the curvature of the smooth surface plate 11r. Similarly, in the curvature adjusting mechanism 40c on the front plate 20f side, the largest radius of curvature that can be formed by the screw hole 24 of the cross beam 23, the roller 105c, and the roller 105d is given in advance as the curvature of the smooth surface plate 11f.

  In order to reduce the curvature radius of the smooth surface plate 11r, the trainer only needs to turn the curvature adjustment handle 51c. The trainee turns the curvature adjusting handle 51c and moves the guide block 56c along the screw shaft 53c to the front of the training machine 10. The guide block 56c moved to the front of the training machine 10 pushes the tip of the arm 55c from the rear plate 20r side. The guide block 56c and the tip of the arm 55c are connected to the linear motion guide device 112 via a hinge 116, and the slider 114 of the linear motion guide device 112 slides smoothly on the guide rail 113. The arm 55c rotates around the shaft 48i. When the arm 55c rotates, the positional relationship between the screw hole 24 of the cross beam 23, the roller 105c, and the roller 105d changes, and the radius of curvature of the smooth surface plate 11r decreases.

  In order to increase the curvature radius of the smooth surface plate 11r, the trainer only needs to turn the curvature adjustment handle 51c in the reverse direction. The curvature radius determined by the screw hole 24 of the horizontal beam 23, the roller 105c, and the roller 105d is increased. The smooth surface plate 11r attempts to return to the original curvature of the predetermined size, and the curvature radius of the smooth surface plate 11r becomes a curvature radius determined by the screw hole 24 of the cross beam 23, the roller 105c, and the roller 105d. The trainee can adjust the curvature of the smooth surface plate 11f in the same manner as the curvature of the smooth surface plate 11r. Since the trainee can adjust the curvature of the smooth surface plate 11r while referring only to the reading of the curvature indicator 96c, the work of adjusting the curvature is easier than in the second modification. Comparing the curvature adjustment mechanism 40c of the modification 4 with the curvature adjustment mechanisms 40f, 40r of the modification 1, the structure of the curvature adjustment mechanism 40c of the modification 4 is simplified, and the operation is easy. Further, the curvature adjustment mechanism 40c of the modification 4 can be lighter and lighter than the curvature adjustment mechanisms 40f and 40r of the modification 1, and the manufacturing cost can be reduced.

  Comparing the curvature adjustment mechanism 40c of Modification 4 and the curvature adjustment mechanism 40a of Modification 2, only the curvature adjustment handle 51c needs to be operated in Modification 4, but the curvature adjustment handles 51a and 51b are operated in Modification 2. Must. Therefore, the curvature adjusting mechanism 40c of the fourth modification is easier to operate. In the fourth modification, the smooth plate 11f and the smooth plate 11r may be a single smooth plate 11, and the central portion in the front-rear direction of the smooth plate 11 may be screwed into the screw hole 24 of the cross beam 23.

  In the present embodiment, the height of the handrail 13 and the interval between the handrails 13 are adjusted by adjusting the positions of the pin holes 31 and 32 through which the pins 34a are inserted. Instead, it is possible to adjust the height of the handrail 13 and the interval between the handrails 13 by configuring the training machine as shown in Modification 5 of FIGS. 14 to 16. FIG. 14 is a right side view showing a part of the training machine according to the fifth modification, with the part broken away, FIG. 15 is a rear view showing a part of the training machine according to the fifth modification, and FIG. It is a rear view of the training machine which concerns.

  Handrail support mechanisms 26 are formed on the front plate 20f side portion and the rear plate 20r side portion of the frame 18 of the training machine 10, respectively. Each handrail support mechanism 26 includes a handrail interval adjustment mechanism 60 and a handrail height adjustment mechanism 70. The handrail interval adjustment mechanism 60 includes guide blocks 28a and 28b, guide shafts 27a and 27b, a screw shaft 62, a handrail interval adjustment handle 63, and a handrail interval scale 93b. Guide shafts 27a and 27b are respectively fixed between the side plates 19a and 19b, and both end portions of the screw shaft 62 are rotatably supported by the side plates 19a and 19b. A right screw is cut in the side plate 19 a side portion of the screw shaft 62, and a left screw is cut in the side plate 19 b side portion of the screw shaft 62.

  The guide blocks 28a and 28b have two shaft holes and one screw hole that penetrate the training machine 10 in the left-right direction. A right screw is cut in the screw hole of the guide block 28a, and a left screw is cut in the screw hole of the guide block 28b. Each of the guide blocks 28a and 28b has one leg hole 29 penetrating in the vertical direction. Guide shafts 27a and 27b penetrate the shaft holes of the guide blocks 28a and 28b, respectively. The right screw portion of the screw shaft 62 is screwed into the screw hole of the guide block 28a, and the left screw portion of the screw shaft 62 is screwed into the screw hole of the guide block 28b. Further, the leg portion 15 of the handrail 13 penetrates the leg hole 29 and projects downward.

  The guide blocks 28a, 28b are constrained to move by the guide shafts 27a, 27b, and cannot rotate around the screw shaft 62. The interval between the guide blocks 28a and 28b is narrowed when the screw shaft 62 rotates in one direction, and widens when the screw shaft 62 rotates in the opposite direction. When the interval between the guide blocks 28a and 28b is reduced, the interval between the handrails 13 is also reduced. When the interval between the guide blocks 28a and 28b is increased, the interval between the handrails 13 is also increased.

  A handrail interval adjustment handle 63 is attached to the end of the screw shaft 62 on the side plate 19 b side, and the screw shaft 62 is configured to be rotatable by the handrail interval adjustment handle 63. A handrail interval scale 93b is formed continuously in the left and right direction of the training machine 10 on the upper end edge of the front plate 20f and the upper end edge of the rear plate 20r of the frame 18, and the position of the leg portion 15 of the handrail 13 is determined by the handrail interval. The scale 93b is readable. The handrail height adjusting mechanism 70 includes a guide block 71, link rods 78a and 78b, a screw shaft 74, a handrail height adjusting handle 77, a window 90b, a handrail height scale 92b, and a handrail height indicator 34c.

  The guide block 71 is an elongated block extending in the left-right direction of the training machine 10 and is located below the handrail interval adjusting mechanism 60. The guide block 71 has guide rails 72a and 72b at the top thereof. The guide rail 72a is located on the side plate 19a side, and the guide rail 72b is located on the side plate 19b side. The lower end of the leg portion 15 of the handrail 13 passing through the leg hole 29 of the guide block 28a rests on the guide rail 72a, and the lower end of the leg portion 15 can move on the guide rail 72a in the longitudinal direction of the guide block 71. It is configured. Similarly, the lower end of the leg portion 15 of the handrail 13 passing through the leg hole 29 of the guide block 28b rests on the guide rail 72b, and the lower end of the leg portion 15 extends on the guide rail 72b in the longitudinal direction of the guide block 71. It is configured to be movable.

  Further, an elongated pin hole 73 continuous in the longitudinal direction of the guide block 71 is formed on the side plate 19 a side of the guide block 71. The screw shaft 74 is located below the guide block 71. Both end portions of the screw shaft 74 are rotatably supported by the side plates 19a and 19b. A handrail height adjustment handle 77 is connected to the end of the screw shaft 74 on the side plate 19 b side, and the screw shaft 74 is configured to be rotatable by the handrail height adjustment handle 77. A screw is cut in the side plate 19a side portion of the screw shaft 74, and a nut 76 is screwed into the screw portion. The side part 19b side part of the screw shaft 74 is a simple round bar, and the screw is not cut. A ring 75 is loosely fitted to the round bar portion. The ring 75 is connected to the frame 18 by a predetermined method.

  The link bar 78a and the link bar 78b are pivoted to each other by a pin 80 at the center, and intersect the "X" shape. An upper end portion of the link bar 78 a is pivotally fixed to the side plate 19 b side portion of the guide block 71 by a pin 81. A lower end portion of the link rod 78 a is pivotally supported by a pin 82 on a nut 76 that is screwed into a screw portion of the screw shaft 74. A pin 83 fixed to the upper end portion of the link bar 78b is slidably fitted in the pin hole 73 of the guide block 71. A lower end portion of the link rod 78 b is pivotally supported by a pin 84 on a ring 75 that is loosely fitted to a round rod portion of the screw shaft 74.

  On the side plate 19b side end of the guide block 71, an indicator needle forming a handrail height indicator 34c is attached. A vertically long window 90b is formed in each of the side plate 19b side portion of the front plate 20f of the frame 18 and the side plate 19b side portion of the rear plate 20r. A scale continuous in the vertical direction is formed on the side of the window 90b, and this scale forms a handrail height scale 92b. The handrail height indicator 34c can be visually recognized from the window 90b. And it is comprised so that the height of the handrail 13 can be known by reading the height of the handrail height indicator 34c using the handrail height scale 92b.

Next, adjustment of the interval of the handrail 13 will be described.
When the trainee turns the handrail interval adjustment handle 63 in one direction and rotates the screw shaft 62 in one direction, the interval between the guide blocks 28a and 28b becomes narrow. Since the leg portions 15 of the handrail 13 on both sides of the smooth surface 12 penetrate the guide blocks 28a and 28b, the handrails 13 move together with the guide blocks 28a and 28b. The lower ends of the leg portions 15 of the handrails 13 are guided by the guide rails 72a and 72b, move on the guide block 71, and approach each other. And the space | interval of both the handrails 13 becomes narrow.

  If the trainee turns the handrail interval adjustment handle 63 in the reverse direction, the interval between the guide blocks 28a and 28b increases and the interval between the handrails 13 also increases. The trainee can read the position of the leg portion 15 of the handrail 13 by the handrail interval scale 93b and can easily know the interval between the handrails 13. Even when the screw shaft 62 rotates, the movement of the guide blocks 28a and 28b is restricted by the guide shafts 27a and 27b, and the guide blocks 28a and 28b do not rotate around the screw shaft 62. Therefore, the guide blocks 28a and 28b are not tilted by the rotation of the screw shaft 62, and the handrail 13 is not tilted.

Next, adjustment of the height of the handrail 13 will be described.
The trainee turns the handrail height adjustment handle 77 in one direction to rotate the screw shaft 74 in one direction. The movement of the nut 76 screwed into the screw portion of the screw shaft 74 is restricted by the link rod 78a. Even if the screw shaft 74 rotates, the nut 76 does not rotate, and the nut 76 moves on the screw shaft 74. When the screw shaft 74 is rotated in a predetermined direction, the nut 76 moves toward the center portion of the screw shaft 74. When the nut 76 moves to the center portion side of the screw shaft 74, the lower end portion of the link rod 78a also moves to the center portion side of the screw shaft 74 together with the nut 76.

  When the lower end portion of the link rod 78a moves toward the center portion of the screw shaft 74, the link rod 78a rotates around the pin 81. Since the lower end portion of the link bar 78 b is fixed to the frame 18, the upper end portion of the link bar 78 b moves along the pin hole 73 of the guide block 71 toward the center portion side of the guide block 71. Accordingly, the distance between the lower end portion of the link bar 78a and the lower end portion of the link bar 78b is reduced, and the distance between the upper end portion of the link bar 78a and the lower end portion of the link bar 78b is increased.

  The height of the lower end portion of the link bar 78b is fixed to the height of the screw shaft 74 and does not change. For this reason, the upper end portion of the link bar 78a rises, and the guide block 71 rises together with the upper end portion of the link bar 78a. Since the lower end of the handrail 13 is placed on the guide block 71, the handrail 13 rises together with the guide block 71. When the trainee tries to lower the height of the handrail 13, the handrail height adjusting handle 77 may be turned in the reverse direction. The trainee can read the position of the handrail height indicator 34c by the handrail height scale 92b, and can easily know the height of the handrail 13.

  Next, another modified example (modified example 6) of the training machine according to the present invention will be described with reference to FIGS. 17 to 25 as appropriate. 17 is a perspective view of a training machine according to Modification 6. FIG. 18 is a front view of the training machine, FIG. 19 is a right side view thereof, and FIG. 20 is an enlarged view of a portion A in FIG. 21 is an enlarged view of part B in FIG. 19, FIG. 22 is an enlarged view of part C in FIG. 19, and FIG. 23 is an enlarged view of part D in FIG.

As shown in FIGS. 17 to 19, the training machine 10 according to the modified example 6 mainly includes a pipe member, and the frame structure is simpler than that of the above-described embodiment or modified example. It has become. In addition, this training machine 10 is an example which does not have the curvature adjustment mechanism of the smooth surface 12. FIG.
Specifically, the training machine 10 includes a support frame 3 formed from a pipe member. The support frame 3 has support legs 2 in the front-rear direction of the smooth plate 11, and each support leg 2 is a pair of support leg main body portions 2 a provided on both sides (left and right direction) of the smooth plate 11. And a connecting beam 2b provided horizontally to connect the pair of supporting leg main body portions 2a to each other.

  Each support leg main body 2a is formed by bending a pipe member into a substantially “J” shape. Then, the substantially “J” -shaped convex portion 2j is directed upward and the long side of the substantially “J” -shaped pipe is disposed outside in the front-rear direction, and an adjuster 9 is disposed at the long end. It is installed. Further, an auxiliary leg 2c is provided on the longer end of the pipe so as to project in the left-right direction of the smooth surface plate 11. An adjuster 9 is also attached to the tip of the auxiliary leg 2c, and the base of the support leg 2 is widened to increase the stability.

  The support legs 2 are connected to each other by a smooth plate support portion 3a having an arc shape. The smooth surface plate support portion 3 a is also formed by bending a pipe member, and the central portion thereof is bent into an arc having a curvature matching the curvature of the smooth surface plate 11. Furthermore, both ends of the portion bent by the arc are horizontal portions 3s. The horizontal portion 3s is formed by being bent back horizontally in accordance with the height of the shorter end portion of the substantially “J” -shaped pipe of the support leg main body portion 2a. Then, the horizontal portions 3s at both ends are welded to the shorter end portion of the substantially “J” -shaped pipe and the middle portion of the longer portion of the support leg main body portion 2a, respectively, so that the support frame 3 is integrated. It is configured without. Furthermore, the smooth surface plate 11 is fixed to a smooth surface plate fixing frame 1 made of a square pipe having a rectangular cross section surrounding the smooth surface plate 11, and the smooth surface plate fixing frame 1 is mounted on the smooth surface plate support portion 3a. It is attached to the support frame 3 by being welded to the support frame 3.

  Further, the training machine 10 is equipped with a pair of left and right handrails 13 via the handrail posture adjusting mechanism 4 with respect to the support frame 3. As shown in FIG. 18, the pair of handrails 13 includes a central portion 14 that extends in the front-rear direction, and leg portions 15 that form a substantially “U” shape by bending both sides of the central portion 14. Further, each of the leg portions 15 on both sides has a handrail support portion 15 s extending horizontally toward the outside in the front-rear direction of the smooth surface plate 11. The handrail posture adjustment mechanism 4 supports the handrail support portion 15s so as to be rotatable and fixable, so that the posture of the handrail 13 can be changed to the standing posture K and the lying posture T shown in FIG. It has become.

Hereinafter, the handrail posture adjusting mechanism 4 will be described in detail.
As shown in FIG. 18, guide shaft support blocks 64 are fixed to the convex portions 2j of the support leg main body portions 2a and the horizontal portions 3s at both ends of the smooth plate support portions 3a. As shown in FIG. 20, these guide shaft support blocks 64 have through holes 64a facing in the vertical direction, and both ends of the handrail height guide shaft 6 are inserted into the through holes 64a, and the set screws 64b on both sides are tightened. The handrail height guide shaft 6 is supported by being inserted. A plurality of pin holes 6 a are formed in the handrail height guide shaft 6, and the pin holes 6 a are arranged in the axial direction of the handrail height guide shaft 6.

  Further, a moving block 65 is disposed between the upper and lower guide shaft support blocks 64. As shown in FIG. 21, the moving block 65 is formed with a through hole 65a facing in the vertical direction, and the handrail height guide shaft 6 is inserted into the through hole 65a with a slight gap. The moving block 65 has a female screw 65m at a position facing the pin hole 6a of the handrail height guide shaft 6 inserted therethrough. A fixed knob 7 having a male screw 7n that can be screwed into the female screw 65m and that can be inserted into each pin hole 6a of the handrail height guide shaft 6 is attached to the female block 65m. Accordingly, the moving block 65 can be moved up and down along the handrail height guide shaft 6 by loosening the fixing knobs 7 on both sides in the front-rear direction and removing the male screw 7n from the pin hole 6a. By tightening and inserting the male screw 7n into the pin hole 6a having a desired height, the handrail height guide shaft 6 is fixed at the position inserted into the desired pin hole 6a, and the height of the handrail 13 can be adjusted. It has become. That is, the handrail posture adjusting mechanism 4 is configured to include a handrail height adjusting mechanism that adjusts the height of the handrail 13.

  Further, as shown in FIG. 20, the moving block 65 is formed with a through-hole 65b that is horizontal and faces in the front-rear direction. The handrail support portion 15s has a small-diameter stepped shaft portion 15j at the tip, and the stepped shaft portion 15j portion is inserted into the through hole 65b. The length of the stepped shaft portion 15j is longer than the length of the moving block 65 in the front-rear direction. And the front-end | tip of the stepped shaft part 15j protrudes from the other side of the through-hole 65b, The external thread 15n is formed in the protruded front-end | tip part, It has the internal thread 8m which can be screwed with this external thread 15n. An adjustment handle 8 is attached.

  Here, the through-hole 65b of the moving block 65 includes a cylindrical hole 65d on the insertion side (left side in the figure) of the handrail support part 15s and a tapered hole part on the mounting side (right side in the figure) of the adjustment handle 8. 65f. The tapered hole portion 65f has a tapered surface that decreases in diameter from the adjustment handle 8 side toward the insertion side of the handrail support portion 15s. A bushing 66 with a hook is inserted between the base end portion of the stepped shaft portion 15j and the cylindrical hole portion 65d, with the hook being the central portion 14 side of the handrail 13, while the stepped shaft portion is A tapered piece 67 is interposed between the tip end side of 15j and the tapered hole portion 65f. The taper piece 67 is a substantially cylindrical member made of resin, and has a tapered surface along the tapered hole portion 65f of the through hole 65b on the outer peripheral surface thereof. The stepped shaft portion 15j and the taper piece 67 each have a key groove on the mutually opposing surface, and a key 68 is inserted into the key groove to prevent the taper piece 67 from rotating with respect to the stepped shaft portion 15j. Yes.

  The taper piece 67 is disposed on the end surface on the bushing 66 side in the axial direction with a gap between the taper piece 67 and the bushing 66, and the end surface on the side on which the adjustment handle 8 is mounted is the moving block 65. It arrange | positions so that it may protrude rather than. The taper piece 67 is brought into contact with the end face 8t of the adjustment handle 8 by tightening the adjustment handle 8, and is pressed toward the bush 66 according to the degree to which the adjustment handle 8 is tightened.

  As a result, the handrail posture adjusting mechanism 4 causes the wedge effect due to the tapered shape of the taper piece 67 and the through hole 65b by tightening the adjustment handle 8, and further elastically deforms the taper piece 67 made of resin. The stepped shaft portion 15j is hugged from its periphery to restrain its rotation. Further, the handrail posture adjusting mechanism 4 releases the wedge effect due to the taper shape between the taper piece 67 and the through hole 65b by loosening the adjustment handle 8, and is stepped by returning to a state where no load is applied to the taper piece 67. The hugging force to the shaft portion 15j is lost and the rotation is allowed.

Furthermore, as shown in FIGS. 17 to 19, the training machine 10 according to the sixth modified example includes a pair of left and right handrails 13 on which a steel rod 37 is stretched as a connecting rod for holding a trainee. And this iron bar 37 has the length adjustment mechanism 5 in the middle part, Moreover, the clamp 38 of both ends is comprised easily with respect to each handrail 13 so that attachment or detachment is possible.
Specifically, as shown in FIGS. 19 and 22, the iron rod 37 includes one first connection pipe 37 a and the other second connection pipe 37 a that is fitted into the connection pipe 37 a and can be taken in and out along the axial direction thereof. And a connecting pipe 37b. As shown in FIG. 22, the first connection pipe 37a has a male thread 37m formed on the outer peripheral surface of the tip thereof, and the second connection pipe 37b can be fitted to the male thread 37m of the first connection pipe 37a. A nut 87 having an internal thread 87n on the inner peripheral surface is fitted. On the inner surface of the nut 87, a tapered portion 87t is formed on the side opposite to the female screw 87n in the axial direction, and the diameter of the tapered portion 87t increases toward the female screw 87n. Further, a tapered piece 88 is inserted between the tapered portion 87t and the second connecting pipe 37b. The taper piece 88 is a resin-made cylindrical member, and has a taper surface along the taper portion 87 t of the inner surface of the nut 87 on the outer peripheral surface thereof. And this taper piece 88 is arrange | positioned so that the end surface by the side of the 1st connection pipe 37a may contact | abut the front-end | tip of the 1st connection pipe 37a.

  The length adjusting mechanism 5 causes the taper 88t to abut on the taper 87t by tightening the nut 87 to produce a wedge effect due to the taper shape between the taper 87t and the outer peripheral surface of the taper piece 88, and is made of resin. By elastically deforming the taper piece 88, the second connecting pipe 37b is clamped from its periphery to restrain relative movement with the nut 87, thereby fixing the positions of the left and right connecting pipes 37a, 37b relative to each other. It has become.

  In addition, the length adjusting mechanism 5 releases the effect of the wedge due to the taper shape between the taper 87t and the outer surface of the taper piece 88 by loosening the nut 87, and the taper piece 88 returns to a shape in which no load is applied. Thereby, the clamping force to the 2nd connection pipe 37b lose | disappears, and a relative movement with the nut 87 is accept | permitted. Therefore, if the relative movement between the second connection pipe 37b and the nut 87 is allowed, the second connection pipe 37b can be taken in and out along the axial direction with respect to the first connection pipe 37a. The length of the iron bar 37 can be adjusted within a predetermined range.

  The second connecting pipe 37b has a plane 37c machined to a predetermined length along the axial direction thereof. In addition, a set screw 37d is mounted on the first connecting pipe 37a on a female screw formed at a position facing the flat surface 37c. A fixing agent such as Loctite (registered trademark) is applied to the set screw 37d, and is fixed in advance to a position having a slight gap from the flat surface 37c. This prevents the second connecting pipe 37b from rotating with respect to the first connecting pipe 37a while adjusting the length of the iron bar 37. Further, the second connection pipe 37b is prevented from unexpectedly coming out of the first connection pipe 37a by bringing the set screw 37d into contact with the end face 37f of the flat surface 37c.

On the other hand, the clamps 38 at both ends of the iron bar 37 have a hugging mechanism for each handrail 13 and can be easily attached and detached by operating the clamp knob 85.
Specifically, as shown in FIG. 23, the clamps 38 at both ends have a substantially “U” -shaped groove 38k that opens downward in the block body 38a, and each handrail 13 is provided in the groove 38k. The center portion 14 is fitted with a slight gap on the left and right. The block main body 38a is provided with a female screw 38m on the opening side of the groove 38k and on the smooth plate 11 side (left side in the figure), and a clamp piece 86 is provided on the opposite side. The clamp piece 86 is connected to the block main body 38a via a support shaft 86a facing the same direction as the central portion 14 of the handrail 13, and can be rotated around the support shaft 86a. The clamp piece 86 is provided with a contact surface 86m that contacts the outer peripheral surface of the central portion 14 of the handrail 13 in the groove 38k when rotated clockwise in FIG. A through hole 86h is provided coaxially therewith.

  The clamp knob 85 has a shaft 85j that can be inserted into the through hole 86h, and a male screw 85n that can be screwed into the female screw 38m is provided at the tip of the shaft 85j. When the clamp knob 85 is tightened, the end face 85t of the clamp knob 85 abuts on the face 86t facing the outside of the clamp piece 86, and the face 86t facing the outside is shown in FIG. Is provided so as to further press clockwise.

  As a result, the clamp mechanism of each clamp 38 inserts the shaft 85j of the clamp knob 85 into the through hole 86h, and further tightens the male screw 85n at the tip of the shaft 85j of the clamp knob 85 into the female screw 38m. The central portion 14 of the handrail 13 is pushed into the back side of the groove 38k by the contact surface 86m. The center portion 14 of the handrail 13 can be clamped by being held by the clamp piece 86. In addition, the clamp mechanism of each clamp 38 loosens the clamp knob 85 to remove the male screw 85n at the tip from the female screw 38m, and further rotates the clamp piece 86 counterclockwise around the support shaft 86a. The central portion 14 of the handrail 13 can be detached from the opening portion of the U-shaped groove 38k.

Next, the operation, action, and effect of the training machine according to Modification 6 will be described with reference to the drawings as appropriate. FIG. 24 is a right side view for explaining the operation of the training machine according to the sixth modification, and FIG. 25 is a perspective view for explaining the operation of the training machine according to the sixth modification.
As described above, the height of the handrail 13 can also be adjusted in the training machine 10 according to the sixth modification. That is, in the training machine 10 of the sixth modification, the moving block 65 can be moved up and down along the handrail height guide shaft 6 by loosening the front and rear fixing knobs 7 and removing the male screws 7n from the pin holes 6a. it can. And it can fix to the position inserted in the desired pin hole 6a of the handrail height guide shaft 6 by fastening the fixing knob 7 and inserting the male screw 7n into the pin hole 6a of the desired height.

  In addition, the training machine 10 according to Modification 6 can also adjust the interval between the pair of handrails 13. That is, in the training machine 10 of this modified example 6, as shown in FIG. 24, the handrail posture adjusting mechanism 4 has a wedge effect due to the tapered shape of the taper piece 67 and the through hole 65b by loosening the front and rear adjustment handles 8. When the taper piece 67 is released and returned to a state in which no load is applied, the clamping force to the stepped shaft portion 15j disappears, whereby the handrail 13 can be rotated around the stepped shaft portion 15j. Therefore, as shown in the figure, the distance between the pair of handrails 13 can be easily adjusted (in addition, when adjusting the distance between the pair of handrails 13, the height of the handrail 13 also changes according to the rotation. ). Therefore, the trainee can be held on the handrail 13 in a posture more suitable for his / her physique.

  And in the training machine 10 of this modification 6, although the example which the iron rod 37 was spanned as a connecting rod which a trainee holds was shown, this iron rod 37 has the length adjustment mechanism 5 in the middle part. Therefore, the length can be easily adjusted according to the width of the handrail 13. Therefore, the trainee can perform the horizontal bar exercise in a posture more suitable for his / her physique. In addition, since the clamps 38 at both ends of the iron bar 37 can be easily attached and detached by operating the clamp knob 85, the trainee can easily attach and detach the iron bar 37 to the handrail 13 as necessary.

  Further, according to the training machine 10 of this modified example 6, the handrail posture adjusting mechanism 4 can change each handrail 13 into a standing posture and a lying posture, so that, for example, as shown in FIG. When the exercise body moves the upper body in the left-right direction of the training machine by taking the lying posture or putting both the handrails 13 in the lying posture, the handrail 13 can be retreated to a position where it does not interfere with the exercise. .

  In particular, for example, when you move your upper body, such as throwing motion with your legs spread, you need to always straddle your legs so that they do not slide down. However, it is easy to perform the exercise because the handrail does not get in the way by placing the handrail 13 in the lying posture during the exercise. In addition, the trainer can easily get on the smooth surface 12 by setting the handrail 13 to the lying posture. And after getting on the smooth surface 12, as shown in FIG. 17, the trainee can also start the desired training using the handrail by positioning the handrail 13 in the standing posture again.
