Description

  The present invention relates to a training apparatus that performs training by performing bending and stretching movements of legs while a user is seated and resists a load applied from the apparatus.

  Conventionally, a training apparatus (multi-exercise machine) as described in Patent Document 1 is known. This training apparatus has a seat on a predetermined frame that can be adjusted with respect to a horizontal plane, and a V that is pivotally provided on a frame on the front edge side of the seat with a base end as a fulcrum. A letter-shaped arm, a pair of horizontally extending roller pads (foot pads) attached to the respective distal ends of the V-shaped arm, and a weight that is detachably attached to the front roller pad, in particular. And.

  According to such a training device, when the training device is used as a leg extension device (a device that is loaded when a leg is stretched), the user is seated on a seat adjusted to a predetermined angle. In the state, by inserting both legs between a pair of roller pads and bending and stretching the legs, the load of the roller pad having a weight is applied to the legs when the legs are stretched, thereby training the legs. it can.

  On the other hand, when using the training device as a leg curl device (a device that is loaded so as to bend the leg), the user must wear a uniform set horizontally including the backrest. When the legs are bent and stretched by inserting both legs between a pair of roller pads while lying on the seat, the load of the roller pad having a weight is applied to the legs when bending the legs. You can train your legs.

  Further, in Patent Document 2, it is possible to set an initial posture of an arm suspended swingably around a fulcrum, and a pad angle regulating plate is attached to the tip of the arm so as to be rotatable about an axis. A leg strength training device in which a roller pad is mounted on a pad angle regulating plate is described. The pad angle restricting plate has a plurality of through holes on a circular locus centered on the axis of the shaft, while the arm has a through hole at a position corresponding to the through hole. By inserting a pin through the through hole and the selected through hole, the phase around the initial axis of the roller pad can be set.

According to such a training apparatus of Patent Document 2, the initial height position of the roller pad is changed by variously changing the initial posture of the arm and the initial phase around the axis of the roller pad, so that the user's sex, height, physical condition, etc. Therefore, the training apparatus can be versatile.
Japanese Utility Model Publication No. 7-17325 No. 7-45241

  However, the leg strength training devices described in Patent Literatures 1 and 2 remain in a state where the front end portion is inclined from the beginning of the seat, for example, for an elderly person or a person who needs assistance, It was necessary to move the waist to a higher position and get in, which was inconvenient. In addition, since detachable weights are used to apply a load to the roller pad, it is necessary to increase or decrease the weight one by one when increasing or decreasing the load on the roller pad according to the physical condition of the trainer. This operation is very troublesome and has the problem that it cannot respond immediately to the demands of the trainee.

  The present invention has been made to solve such problems, and is particularly easy for an elderly person or a person who needs assistance, and can easily adjust the load to be applied to the roller pad. Thus, an object of the present invention is to provide a training device that can be immediately used for training of leg strength in a desired state.

The invention according to claim 1 is a seating mechanism provided on the apparatus main body, a training mechanism part provided in front of the seating, and having a mechanism for causing the user's leg to exercise, and the training mechanism part. comprising a load applying unit that gives a braking force to be adjusted electrically to the movement, and a tilt adjustment unit for tilting the front end of the attachment seat in the vertical direction, the training mechanism is disposed horizontally, the user A pair of roller pads for sandwiching the legs, and switching between the pair of roller pads between a first position for sandwiching the legs of the user and a second position for opening the legs. and a structure having a detection unit for detecting that said pair of rollers pad is in at least one of orientation of the first position and the second position, the tilt adjustment section, the by the detection unit A pair of roller pads When it is in the first posture is detected, it is characterized in that it is intended to prohibit the tilting movement of the wear seat.

  According to the above configuration, since the front end portion of the seating is provided with the inclination adjusting portion that inclines in the vertical direction, when the user gets into the training apparatus, the seating is performed by keeping the seating in a horizontal state. Can be made easier. In particular, it is very useful for an elderly person or a person who needs assistance, because it is not necessary to sit up with the hips raised as in the case of getting into a conventional apparatus, and the user can simply sit on a chair. After the user is seated, the front end of the seat can be tilted upward to be displaced to a position where training can be performed.

Further, in the present apparatus, the load applying unit applies a braking force (that is, a load) that is electrically adjusted to the movement of the training mechanism unit. Therefore, the load can be easily controlled by electrical control. And it becomes possible to adjust immediately. Therefore, conventionally, it is impossible to adjust the load unless the weight is changed or increased / decreased, and the inconvenience that it is very troublesome and cannot immediately respond to the user's request is solved, The training device is very easy to use and versatile . Furthermore, since this apparatus electrically applies a load, when the user raises the leg (shin part) from below to above (extends the leg), a so-called leg extension device applies a load downward from the apparatus. It can also be used as a so-called leg curl device that applies a load upward from the device when lowering the leg from above (bending the leg), and can easily change the training item freely with the same device I can .

In the invention described in claim 1, the training mechanism having a mechanism for causing the user's leg to exercise functions when the user actively exercises the leg with his / her own force. In addition to this, the user also includes a function that allows the legs to be moved dynamically by driving predetermined driving means without moving the legs by their own power .

In addition, in this apparatus, a user sitting on the seat facing forward can sandwich a leg portion between a pair of roller pads during training, so that the leg portion is paired for both when extended and bent. Since it hits one of the roller pads, it is reliably prevented that the leg part comes off the roller pad. When the roller pad is used as a leg extension device (device that is loaded when the legs are extended), the front roller pad functions as a load-applying contact portion, while the roller pad is legged. When used as a curling device (a device that is loaded when the leg is bent), the rear roller pad functions as a load-applying contact portion .

Therefore, the user can execute training in a posture in which the user sits on the seat facing forward regardless of whether the roller pad is used as a leg extension device or a leg curl device. Thus, depending on which one is used, it is not necessary to sit on the seat or to sit down (prone), and the training apparatus becomes very easy to use .

The pair of roller pads includes a switching structure in which at least one of the pair of roller pads switches between a first posture that sandwiches the leg portion and a second posture that opens the leg portion. With the load pad set to the second posture, the leg portion is positioned at a position where it can be sandwiched between the pair of roller pads, and then one of the roller pads is returned from the second posture to the first posture. The leg portion is easily sandwiched between the pair of roller pads .

Further, in this apparatus, when the detection unit detects that the pair of roller pads is set to the first posture, that is, when the roller pad is sandwiched between the user's legs. The seating is controlled so as not to tilt. The reason for this control is that if the seat is tilted while the user's legs are sandwiched, the contact of the roller pad to the user's legs remains almost fixed, and only the seating This is because there is a possibility that an excessive load is applied to the leg of the user because it moves. For example, if the seat before the start of training is horizontal, if the user's leg is sandwiched between the roller pads and only the seat is tilted upward in this state, the user's leg is partly fixed. This is not desirable because a force that is stretched while being applied is applied. On the contrary, if the user's legs are sandwiched between the roller pads after the training is finished and only the seating is lowered, a force is applied in the direction in which the legs are contracted, which is not desirable. . In this regard, according to the configuration of the present claim, since the detection unit detects in advance the possibility that the roller pad may pinch the user's leg, the control is performed so that the above situation does not occur. Therefore, it is possible to avoid inconvenience that a load may be applied to the leg of the user in advance .

In addition, since the detection unit is configured to detect that one roller pad is in at least one of the first posture and the second posture, the two detection units are set to set both postures. Compared with the case of providing, the number of parts is reduced .

In the invention according to the first aspect, the tilt of the seating is prohibited when it is detected that the roller pad is sandwiching the leg of the user. It is also possible to detect that the roller pad does not sandwich the user's leg (at least one of the roller pads is open), and only in such a case, the control of allowing the seat to be tilted can be performed .

According to a second aspect of the present invention, in the first aspect of the invention, the pair of roller pads are arranged in parallel to each other and in the front-rear direction with respect to the user in a top view in the first posture, In the second posture, one of the roller pads disposed on the front side is set in the upright posture by the switching structure provided at the end of the roller pad.

  According to such a configuration, of the pair of roller pads sandwiching the user's legs, the front roller pad can be flipped up from the horizontal posture to the upright posture, and the user can place the leg on the rear roller pad. It is possible to achieve the pinching of the leg by simply lowering the front with a roller pad on the front with the part placed. Therefore, for example, in a device in which a pair of roller pads is in a fixed state, the leg portion is inserted into the gap from the side of the roller pad, and the leg portion is slid and moved to an appropriate position. Although this is necessary and extremely inconvenient, the present apparatus eliminates such a problem. This is also intended for the convenience of elderly people and those who require assistance, and has a very useful effect that the user does not have to take an unreasonable posture or action when using the device. is there.

The invention according to claim 3 is the invention according to claim 2 , further comprising: a lock structure that holds the second posture of the one roller pad; and an operation unit that releases the lock state of the lock structure, The operation unit is provided at a position where the user seated on the seat can operate.

  According to such a configuration, one of the roller pads is locked by the lock structure in the state of being set to either the first or second posture, and therefore during the training, the user's leg can bend and stretch. There is no inconvenience that one roller pad moves toward the second posture, and the first posture of one roller pad is maintained. In addition, when the roller pad set in the second posture is locked by the lock structure when the user gets on and off the seat, the roller pad in the second posture maintains the upright posture. There is no need to perform troublesome operations such as pressing by hand, and the user can easily get on and off the seat.

  In addition, since the operation unit is provided at a position where the user seated on the seat can operate, the user seated on the seat operates the operation unit by himself without relying on another person to operate the roller. This makes it possible to lock and unlock the set posture of the pad, which is convenient.

According to a fourth aspect of the present invention, there is provided the arm according to any one of the first to third aspects, wherein the arm is pivotally supported by a shaft extending in the left-right direction of the apparatus body so as to be swingable, and supports the pair of roller pads And a relay member interposed between the arm and the pair of roller pads, the position of the arm in the longitudinal direction being adjustable.

  According to such a configuration, when the user seated on the seat is bent and stretched with the leg portion sandwiched between the pair of roller pads, the arm rotates about the axis extending in the left-right direction of the apparatus body, and the leg of the user The part is trained under this load. Since a relay member whose position in the longitudinal direction of the arm is adjustable is interposed between the arm and the pair of roller pads, the relay member allows the arm to be adjusted according to the gender and physique of the user. By setting the length, the roller pad is adapted to the sex, physique, etc. by the bending and stretching movements of the user's legs, and training is performed appropriately.

According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, the detection unit is arranged on the front side of a pair of roller pads disposed in the front-rear direction with respect to the user. It is characterized by detecting the posture of the roller pad provided.

  According to this configuration, the detection unit detects whether the roller pad on the front side is set to the first posture (horizontal posture) or the second posture (upright posture). This indicates that the posture of the roller pad on the front side can be changed, and the posture of the roller pad on the front side can be changed as compared with the case where the posture of the roller pad on the rear side can be changed. It is easy to get on and off the seat and to sandwich the leg between the pair of roller pads.

The invention according to claim 6 is the invention according to any one of claims 3 to 5 , further comprising an input device for accepting an operation input to the device main body by a user, wherein the tilt adjustment unit is input to the input device. Only when the operation is continued, the seat is tilted.

According to such a configuration, since the inclination angle of the seating is sequentially changed only while the input operation to the operation unit is continued (that is, only while the operation of the operation unit is continued), the user who is seated on the seating Can sense the sequentially changed angles and the state of their legs, and can arbitrarily adjust the angle while resting the legs appropriately. Therefore, for example, when the angle of the seating is automatically changed to a preset angle by a single operation of the operation unit, there is an inconvenience that an excessive load is applied to the legs depending on the change speed. Although this may occur, according to the invention of claim 6 , such a situation can be avoided in advance.

  According to the first aspect of the present invention, since the front end portion of the seating is provided with the inclination adjusting portion that inclines in the vertical direction, when the user gets into the training apparatus, the seating is kept in a horizontal state. Therefore, the seating can be facilitated. In particular, it is very useful for an elderly person or a person who needs assistance, because it is not necessary to sit up with the hips raised as in the case of getting into a conventional apparatus, and the user can simply sit on a chair.

In addition, at least one of the pair of roller pads includes a switching structure that switches between a first posture that sandwiches the leg portion and a second posture that opens the leg portion. With the load pad set to the second posture, the leg portion is positioned at a position where it can be sandwiched between the pair of roller pads, and then one of the roller pads is returned from the second posture to the first posture. The leg portion can be easily sandwiched between the pair of roller pads. In addition, when the detection unit detects that the pair of roller pads is set to the first posture, that is, when the roller pad is sandwiched between the user's legs, the seating is Since it is controlled not to perform the tilting operation, it is possible to avoid inconvenience that a load may be applied to the leg of the user in advance .

According to the second aspect of the invention, of the pair of roller pads sandwiching the user's legs, the front roller pad can be flipped up from the horizontal posture to the upright posture. The foot can be pinched by simply putting it down with the front roller pad placed on the foot with the foot placed on it, and the user does not have to take an unreasonable posture or action when using the device. It has a very useful effect.

According to the third aspect of the present invention, since the front roller pad is locked by the lock structure in the state set in either the first or second posture, the leg of the user is bent and stretched during training. There is no inconvenience that the front roller pad moves toward the second posture even by movement, and the first posture of the front roller pad can be maintained.

  In addition, since the roller pad set in the second posture does not move when the user gets on and off the seat, there is no need to perform troublesome operations such as pressing the roller pad one by one. You can easily get on and off the seat.

  In addition, since the operation unit is provided at a position where the user seated on the seat can operate, the user seated on the seat operates the operation unit by himself without relying on another person to operate the roller. The set posture of the pad can be locked and unlocked.

According to the invention described in claim 4, when the user seated on the seat is bent and stretched with the legs sandwiched between the pair of roller pads, the arm rotates about the axis extending in the left-right direction of the apparatus body, The user's leg is trained under this load. Since a relay member whose position in the longitudinal direction of the arm is adjustable is interposed between the arm and the pair of roller pads, the relay member allows the arm to be adjusted according to the gender and physique of the user. By setting the length, the roller pad is adapted to the gender, physique, etc. due to the bending and stretching movements of the user's legs, thereby enabling proper training.

According to the fifth aspect of the present invention, the detection unit detects whether the front roller pad is set to the first posture or the second posture. Based on the detection result, the front roller pad is set to the front roller pad. By performing a predetermined posture change, the user can easily get on and off the seat and sandwich the leg between the pair of roller pads compared to the case where the posture of the roller pad on the rear side can be changed. it can.

According to the sixth aspect of the invention, the seating angle is sequentially changed only while the input operation to the operation unit is continued (that is, only while the operation of the operation unit is continued). The user can sense the sequentially changed angles and the state of his / her legs one by one, and can arbitrarily adjust the angle while resting the legs appropriately.

The rectangular tube arm body 412 is positioned with respect to the arm main body 411 by being fitted into any of the holes. When changing the position of the rectangular tube arm body 412 with respect to the arm main body 411, the arm main body 411 is pulled outward against the urging force of the urging means, and the tip of the adjustment knob 414 is moved to the locking hole. What is necessary is just to move the said adjustment knob 414 in the state which eliminated insertion. By doing so, the position of the rectangular tube arm body 412 with respect to the arm main body 411 can be changed.

  The roller pad support plate 42 supports a pair of roller pads 43 (a front roller pad 43a and a rear roller pad 43b), and the arm 41 is suspended from a load transmission shaft 571 described later (FIG. 4). The central portion is fixed to the square tube arm 412 so that the rear end side is slightly higher than the front end side.

  The roller pad support plate 42 has a pair of roller pad support shafts 44 (a front support shaft 44a and a rear support shaft 44b) projecting rightward from the front and rear end portions. Roller pads 43 are pivotally supported on the shafts 44 so as to be rotatable around the axis.

  The roller pad 43 is externally fitted to a cylindrical body 431 made of a rigid material such as a metal or hard synthetic resin so as to be rotatably fitted to the roller pad support shaft 44, and to the cylindrical body 431 so as to be integrally rotatable. And a roller pad body 432 made of a flexible material such as soft synthetic resin or foaming synthetic resin. The roller pad 43 is prevented from being detached from the roller pad support shaft 44 by mounting a retaining member 433 on the tip surface of the roller pad support shaft 44 in a state of being fitted on the roller pad support shaft 44. It has become so.

  In the present embodiment, the front roller pad 43a of the pair of roller pads 43 has a horizontal posture (first posture) S1 shown in FIG. 5 extending horizontally from the roller pad support plate 42 to the right. The posture can be changed between the upright posture (second posture) S2 shown in FIG. 4 which is upright by bending the proximal end portion of the front support shaft 44a, and the posture is set in each posture. The posture is locked by the lock structure 45.

  FIG. 6 is a partially cutaway perspective view for explaining the lock structure 45 of the front roller pad 43a, FIG. 6A is an exploded perspective view, and FIG. 6B is an assembled perspective view. The direction display by X and Y in FIG. 6 is the same as in FIG. 1 (X is the left-right direction (−X: leftward, + X: rightward), Y is the front-rear direction (−Y: forward, + Y: rearward). )).

  First, as shown in FIG. 6, the front support shaft 44a that supports the front roller pad 43a includes a columnar bracket 441 that protrudes from the roller pad support plate 42 and has a bifurcated tip, and this columnar bracket. And a support shaft main body 442 connected to 441.

  The cylindrical bracket 441 is formed with a vertically extending gap 443 formed by being cut leftward from the distal end surface, while the left end surface of the support shaft main body 442 can be fitted into the gap 443. A tongue piece 444 is projected.

  The tongue piece 444 has a connecting hole 444a penetrating at an appropriate position through which the center line of the support shaft main body 442 passes, and the cylindrical bracket 441 also has a gap 443 at a position corresponding to the connecting hole 444a. The connecting hole 441a is formed through.

  Then, with the tongue piece 444 fitted in the gap 443, the connecting pin 445 is inserted into the connecting holes 441a and 444a and caulked so that the support shaft main body 442 can rotate around the connecting pin 445. It is connected to the bracket 441. As shown in FIG. 6B, the support shaft main body 442 (that is, the front roller pad 43a) has a horizontal posture S1 that extends rightward as the front roller pad 43a is rotated around the connecting pin 445. The posture can be changed between the upright posture S2 upright from the connecting pin 445.

  As shown in FIG. 6A, the tongue piece 444 has a fan-shaped portion 444b having a lower edge bulging downward in a state where the front roller pad 43a is set in the horizontal posture S1. The fan-shaped portion 444b is formed in an arc shape with the center of curvature of the hole center of the connecting hole 444a. The fan-shaped portion 444b is provided with a first locking hole 444c on the right side in the state shown in FIG. 4A on a concentric circle with the center of curvature of the connecting hole 444a as the center of curvature. A second locking hole 444d is formed on the side.

  The connecting hole 444a is formed by a straight line connecting the core of the first locking hole 444c and a straight line connecting the core of the connecting hole 444a and the core of the second locking hole 444d. The angle α is set to approximately 90 °.

  In addition, a bracket 422 protruding rightward by a predetermined distance is provided at a position immediately below the cylindrical bracket 441 on the right surface side of the roller pad support plate 42, and a right end portion of the bracket 422 is provided. A guide cylinder 423 through which a locking pin 454 described later is penetrated so as to be movable back and forth is fixed. The guide cylinder 423 is set at an installation position so as to face the first and second locking holes 444c and 444d on the rear surface side of the tongue piece 444.

  The switching structure according to the present invention for switching the front roller pad 43a between the horizontal posture S1 and the upright posture S2 includes a gap 443 formed in the cylindrical bracket 441, and a tongue of the support shaft main body 442 fitted in the gap 443. It consists of a piece 444, a tongue piece 444 fitted in the gap 443, a connecting pin 445 penetrating through the column bracket 441, and the like.

  The lock structure 45 is mounted in a center hole 421 formed in the center of the roller pad support plate 42 and protrudes to the right, and is rotatable about the protrusion shaft 451. An externally-fitted operation lever 452 and a vertically extending member that has a rectangular shape hanging from the front end of a projecting rod piece 453a projecting forward from the peripheral surface of the base end cylindrical body 452a. A locking plate 453 provided with a locking hole 453b, and a locking pin 454 fitted into the first locking hole 444c or the second locking hole 444d by the rotation of the locking plate 453 around the projecting shaft 451, It has.

  In the state where the operation lever 452 is mounted on the roller pad support plate 42, the locking hole 453b of the locking plate 453 faces the rear end surface of the guide cylinder 423 as shown in FIG. The installation position is set as follows. The locking hole 453b has a hole width dimension set to be slightly wider than the diameter dimension of the locking pin 454, so that the locking pin 454 can be inserted therethrough.

  The locking pin 454 includes a pin main body 454a that passes through the guide cylinder 423 in a sliding state, and a flange 454b that is externally fitted and fixed at a position slightly forward from the rear end of the pin main body 454a. , And a nut 454c that is screwed onto a male screw screwed at the rear end of the pin body 454a. As shown in FIG. 6 (B), the locking pin 454 has a front portion penetrating through the guide cylinder 423 from the flange 454b of the pin main body 454a and a rear portion from the flange 454b engaged with the locking plate 453. The nut 454c is screwed to the rear end portion of the pin main body 454a in a state of being penetrated through the stop hole 453b, so that the nut 454c is attached to both the guide cylinder 423 and the locking plate 453 in a retaining state. ing.

  Further, such a locking pin 454 protrudes from the front end portion of the guide cylinder 423 in a state where the operation lever 452 is tilted rearward as shown by a solid line in FIG. 6B. 2 is able to penetrate the locking holes 444c and 444d, while the operation lever 452 is operated to the front, so that as shown by a two-dot chain line in FIG. Thus, the length dimension is set so as to move away from the first and second locking holes 444c and 444d.

  As shown in FIG. 6B, when the locking pin 454 is fitted in the first locking hole 444c, the horizontal posture S1 of the front roller pad 43a is locked, while the locking pin 454 is In the state of being fitted into the two locking holes 444d, the upright posture S2 of the front roller pad 43a is locked. In any case, when the posture of the front roller pad 43a is locked, the operation lever 452 is tilted rearward.

  In order to change the posture of the locked state of the front roller pad 43a, the operation lever 452 may be operated forward and the operation lever 452 may be rotated counterclockwise around the protruding shaft 451. . By doing so, the locking plate 453 having the rear portion of the pin main body 454a penetrated through the locking hole 453b rotates counterclockwise around the protruding shaft 451 and presses the nut 454c rearward. The pin 454 moves toward the rear.

  The front end of the pin body 454a is disengaged from the first or second locking holes 444c and 444d (the first locking hole 444c in the example shown by the solid line in FIG. 6B) by the movement toward the rear of the locking pin 454, As a result, the locked state of the front roller pad 43a is canceled. By rotating the roller pad 43 around the connecting pin 445 in a state where this lock is released, the posture of the front roller pad 43a is changed.

  Then, after the posture is changed, if the operation lever 452 operated forward is operated backward, the locking plate 453 rotates around the protruding shaft 451 in the clockwise direction. As a result, the locking plate 453 presses the flange 454b of the pin main body 454a passing through the locking hole 453b forward, so that the front end of the pin main body 454a is in the first or second locking hole 444c, 444d. The posture (horizontal posture S1 or upright posture S2) of the front roller pad 43a is locked.

  Although not shown in FIG. 6, an urging member is provided at an appropriate position on the roller pad support plate 42, and the urging member urges the operation lever 452 clockwise around the projecting shaft 451. Then, the operation lever 452 is once turned counterclockwise to unlock the front roller pad 43a, and the front roller pad 43a is slightly rotated around the connecting pin 445, and then the operation lever 452 is operated. When the hand is released, the front end of the locking pin 454 relatively slides on the rear surface of the fan-shaped portion 444b according to the turning operation of the front roller pad 43a by the urging force of the urging means.

  When the rear roller pad 43b is rotated by approximately 90 ° and the front end of the locking pin 454 reaches a position facing the first or second locking holes 444c and 444d, the locking pin 454 is The front roller pad 43a is locked in the posture after the posture change even if the operation lever 452 is not particularly operated at this time because it is fitted into the first or second locking holes 444c, 444d by the urging force.

  In the lock structure 45, when the user gets into the seat 32 or gets off the seat 32, the operation lever 452 is operated, and the front roller pad 43a is unlocked in the horizontal posture S1 and the front roller is released. The pad 43a is set in the upright position S2 as shown in FIG. 4, and the front position of the seating 32 is in a state in which there is no obstacle to the seating. You can get on and off.

  Further, since the operation lever 452 is provided at a position where the user can operate with one hand while sitting on the seat 32, the user does not have to borrow a hand after training. It is possible to easily get off the seat 32 after operating the operation lever 452 to release the lock and changing the posture of the front roller pad 43a which has been in the horizontal posture S1 to the upright posture S2.

  In addition, a user who gets into the seating 32 with the front roller pad 43a set in the upright posture S2 changes the posture of the front roller pad 43a to the horizontal posture S1, so that the user's feet As shown in FIG. 5, since it is sandwiched between the front roller pad 43 a and the rear roller pad 43 b by itself, it is troublesome to insert the foot between the pair of roller pads 43 after sitting on the seat 32. It is convenient because you do not have to do anything.

  In addition, a roller pad position detection sensor 46 (corresponding to a detection unit in claims) is provided at a position above the cylindrical bracket 441 on the right surface side of the roller pad support plate 42. This function will be described below. The control unit 70 prohibits the tilting operation of the seat 32 according to the detection signal from the roller pad position detection sensor 46. Specifically, when it is detected by the roller pad position detection sensor 46 that the roller pad 43 is sandwiched between the user's legs, the seat 32 is controlled so as not to tilt. The reason for this control is that if the seat 32 is tilted with the user's legs sandwiched, the contact state of the roller pad 43 with the user's legs remains substantially fixed. This is because only 32 moves, and there is a possibility that an excessive load is applied to the leg of the user. For example, in the state where the seating before the start of training is horizontal, if the user's legs are sandwiched between the roller pads 43, the front end of the seating 32 (in more detail, the seats constituting the seating 32) If only the front end portion of the bottom 321 is described below as the front end portion of the seating seat 32), the user's leg portion is stretched with a part of the leg portion being fixed. This is not desirable. On the contrary, if only the front end of the seating seat 32 is lowered while the user's leg is sandwiched between the roller pads 43 after the training is finished, a force is applied in the direction in which the leg is contracted, contrary to the above. So it is not desirable. In this regard, since the roller pad position detection sensor 46 detects in advance a case where the roller pad 43 may pinch the user's leg, and the control is performed so that the above situation does not occur. It is possible to avoid inconvenience that a load may be applied to the legs in advance. Therefore, in this embodiment, when the front roller pad 43a is in the horizontal posture S1, that is, when there is a possibility that the user's leg is sandwiched between the pair of roller pads 43, the seat portion 32 does not tilt, Only when the front roller pad 43a is in the upright posture S2, that is, when the roller pad 43 is opened, and the angle adjustment switch of the input device 63 is operated, the seat portion 32 performs the tilting operation.

  In the above, the inclination of the seat 32 is prohibited when it is detected that the roller pad 43 is sandwiching the leg of the user. However, as another form, the roller pad 43 is used conversely. It is also possible to detect such a state that the person's leg is not sandwiched (that is, at least one of the roller pads is open), and only in such a case, the control of permitting the inclination of the seating seat 32 can be taken.

  The roller pad position detection sensor 46 may be a limit switch that is mechanically pressed by the support shaft body 442 of the front support shaft 44a when the front roller pad 43a is set in the upright posture S2, and may be supported. A so-called optical sensor using a photocoupler (optical coupling element) configured such that the optical path is shielded by the shaft main body 442 may be used. Further, the sensor installation location is not limited to the above position as long as it can be determined whether the roller pad 43 is in a state where the user's legs can be sandwiched or in an open state.

  Returning to FIG. 1, the load applying unit 50 applies a load to the swing of the roller pad 43 due to the bending and stretching movement of the leg of the user, and is provided on the second base 22 side.

  The load applying unit 50 is disposed at the lower part of the horizontally long frame 223 (actually, the servo motor is installed at the left position of the first base 21 with the second base 22 aligned with the first base 21). (Electric load generating means) 51, a first sprocket 52 pivotally supported so as to be integrally rotatable with a drive shaft of the servo motor 51, and a bifurcated shape fixed on a flat plate base 221 in the vertically long frame 222 A lower bracket 53, a second sprocket 54 pivotally supported so as to be integrally rotatable about an installation shaft 531 provided between two forks of the lower bracket 53, and the second sprocket 54 and the first sprocket 52 A first chain 55 stretched between them, a third sprocket 56 pivotally supported by the lower bracket 531 so as to rotate integrally therewith, and the longitudinal frame 222 A bifurcated upper bracket 57 provided at the top, a fourth sprocket 58 that is supported concentrically and integrally with a load transmission shaft 571 extending in the left-right direction, spanned between the two forks of the upper bracket 57, and A fourth chain 59 is provided between the fourth sprocket 58 and the third sprocket 56.

  The first chain 55 and the second chain 59 are always kept in tension by a tension sprocket (not shown).

  The load transmission shaft 571 has a mounting hole 572 formed concentrically on the right end surface thereof, and a fulcrum shaft 413 projecting from the arm body 411 of the roller pad portion 40 is fitted into the mounting hole 572. In this state, unillustrated pins are inserted into the load transmission shaft 571 and the fulcrum shaft 413, so that the swing of the roller pad 43 is transmitted to the load transmission shaft 571 via the fulcrum shaft 413.

  When the roller pad 43 is rotated clockwise around the fulcrum shaft 413 by the user seated on the seat 32 extending the leg, the servo motor 51 is rotated by the control of the control unit 70. A predetermined load is applied in a direction opposite to the direction. Conversely, when the roller pad 43 is rotated counterclockwise around the fulcrum shaft 413 by returning the legs once extended by the user to the original bent state, the power to the servo motor 51 is controlled by the control of the control unit 70. The supply is cut off, so that the roller pad 43 rotates counterclockwise in a substantially unloaded state.

  In order for the control unit 70 to perform such control on the servo motor 51, a second detected plate 573 is provided on the left end surface of the load transmission shaft 571 so as to be integrally rotatable as shown in FIG. On the other hand, a direction sensor 24 for detecting the rotation direction of the second detected plate 573 is provided at a position facing the second detected plate 573 at an appropriate position of the vertically long frame 222. The rotation direction of the detection plate 573 (that is, the rotation (swing) direction around the fulcrum shaft 413 of the roller pad 43) is detected.

  The input / output unit 60 is used to input various types of information related to training and to output the status of training. Such an input / output unit 60 is provided on a top of a leg 61 mounted in the upper bracket 57 from above, and a rotary disk 62 that is rotatable around a vertical axis (not shown) and is a box-shaped input device 63 in appearance. Is configured by being mounted.

  The leg portion 61 is formed in a bifurcated shape, and is fixed to the top plate of the vertically long frame 222 in a state where the bifurcated portion is mounted in the upper bracket 57 so as to straddle the load transmission shaft 571.

  The input device 63 is provided with a display portion 631 made of an LCD (Liquid crystal display) on one surface of the box-shaped casing facing the seating 32 and a plurality of input keys (not shown) on the same surface. From this input key, the user's personal information, desired training content, and the like are set. Such personal information or the like is displayed on the display unit 631 for input confirmation.

  Further, when training is started, the training execution time, the number of leg bending and stretching movements, and the like are displayed on the display unit 631, so that the user can recognize the status of the training currently being performed one by one. It has become.

  In addition, by rotating the rotary disk 62 about the vertical axis, the direction of the display unit 631 of the input device 63 mounted on the rotary disk 62 is made easy for a user sitting on the seat 32 to see. Can do.

  In this embodiment, the input device 63 is provided with an angle adjustment switch (operation unit) 632 for adjusting the angle of the seat bottom 321, and the angle adjustment switch 632 is operated in one direction from the neutral position. Only during the operation, the piston rod 332 of the electric linear actuator 33 protrudes and the angle of the seat bottom 321 with respect to the horizontal plane gradually increases to reach a predetermined constant angle, while continuing to operate in the other direction. As a result, the angle of the seat bottom 321 gradually decreases and returns to the original angle. Then, when the angle adjustment switch 632 is released after the angle of the seat bottom 321 reaches a predetermined constant angle or returns to the original angle, the angle adjustment switch 632 returns to the original middle vagina position. Has been made.

  As described above, since the angle of the seat 32 is sequentially changed only while the input operation of the angle adjustment switch 632 is continued, the user seated on the seat 32 can change the angle to be changed sequentially and the state of his / her leg. A sense of unity can be felt, and the angle can be adjusted arbitrarily while the legs are properly rested. Therefore, for example, when the seating portion is automatically changed to a preset angle by a single operation, there may be a problem that an unreasonable load is applied to the leg portion depending on the change speed. However, according to the present embodiment, such a situation can be avoided in advance.

  In the present embodiment, the inclination angle of the seat 32 is constant regardless of the user.

  The control unit 70 controls the initial position of the roller pad 43 related to the training by the training device 10, the load by the servo motor 51, the inclination angle of the seat bottom 321, and the like. Based on the input information of the user input from the input device 63 by executing a predetermined program stored in the storage unit, the control unit 70 receives a detection signal from the angle sensor 23 and a signal from the direction sensor 24. A control signal is output to the electric linear actuator 33 and the servo motor 51 while referring to the detection signal, thereby setting an inclination angle of the seat bottom 321, setting an initial angle of the arm 41, and further applying to the roller pad 43. The load level (braking force) is set.

  In order to perform such control, the storage unit included in the control unit 70 stores input information such as the user's sex, age, and height, and the initial position of the roller pad 43 for each angle of the seat bottom 321 set by the user ( An initial height position) and a table in which values of loads applied to the roller pad 43 are set are stored. And the control part 70 sets the initial position and load amount of the roller pad 43 for the said user for the said user in light of the input information from the input device 63 of a user in the said table.

  The order of use of the training apparatus according to the present embodiment having the structure described above will be described below. First, as shown in FIG. 4, the user is a device in which the seat 32 is in a horizontal state, and the roller pad 43 a disposed in front of the pair of roller pads 43 is in the upright posture S <b> 2. Sitting against. If the roller pad 43a is also in the horizontal posture S1, the operation lever 452 is operated to release the locked state (fixed state) of the roller pad 43a, and the hand is lifted to the upright posture S2. As is clear from FIG. 4, in this state, the seating seat 32 is not in an inclined state for training, and the roller pad 43a is in a position that does not obstruct the seating. It is possible to sit on the seat 32 as easily as sitting on the seat.

  Next, the user operates the angle adjustment switch 632 of the input device 63 in the seated state to tilt the front end surface of the seat 32 upward. At this time, the roller pad 43a remains in the upright posture S2. This is because, as described above, if the seat 32 is tilted with the legs sandwiched, an excessive load may be applied to the legs. As described above, the posture of the roller pad 43a is detected by the roller pad position detection sensor 46, and if it is in the horizontal posture S1 (in a state where there is a possibility that the user's leg may be sandwiched). Since the tilting operation of the seating 32 is prohibited, the tilting operation is not performed.

  Next, when the seat 32 is tilted to a predetermined angle (no further tilt), the user operates the operation lever 452 to release the locked state of the roller pad 43a and tilt it downward. Actually, the user moves down while supporting the roller pad 43a with the left hand. As a result, the user's legs are sandwiched between the pair of roller pads 43. Thus, in this embodiment, since the leg portion is sandwiched by opening and closing the roller pad on one side, for example, the leg portion is not inserted into the gap between the pair of fixed roller pads, Users do not have to take an unreasonable posture. This state is shown in FIG.

  In this state, the user starts training. After the training is completed, the steps reverse to the above are performed. That is, the user first operates the operation lever 452 to release the locked state in the horizontal posture S1 of the roller pad 43a and change the posture to the upright posture S2. Actually, the user performs an operation of putting the hand on the roller pad 43a and lifting it upward. Here, in the state where the roller pad 43a is set in the upright posture S2 in this way, the contact state between the user's leg and the pair of roller pads is released, and the seating 32 can be tilted. Become. Next, the user operates the angle adjustment switch 632 of the input device 63 to tilt the front end portion of the seating seat 32 downward so as to be in a horizontal state. In a state where the seating 32 is horizontal, the user gets off the seating 32 and finishes the training.

  FIG. 7 shows the positional relationship between the seating seat 32 and the roller pad 43 after the end of training. As will be described later, in the present embodiment, the front end portion of the seating seat 32 and the roller pad 43 do not interfere with each other. It is a figure for demonstrating performing various operation | movement. 7A is a state immediately after the training is completed, FIG. 7C is a state in which the seat bottom 321 is returned to the horizontal posture, and FIG. 7B is a diagram showing the progress in the middle. . Both are side views. In addition, the direction display by Y in FIG. 7 is the same as that in FIG. 1 (−Y: forward, + Y: backward).

  As shown in FIG. 7A, at the end of the training, the seating seat 32 is in a state where the front end portion thereof is inclined upward. On the other hand, the arm 41 having the roller pad 43 is suspended from the fulcrum shaft 413 as shown. Since the user gets off the seating 32 after the training, the seating 32 is first returned to the horizontal state. However, if the seat 32 is lowered while the arm 41 is suspended as shown in FIG. 7A, the roller pad 43 and the front end of the seat 32 interfere with each other depending on the position of the roller pad 43. there is a possibility. As described above, since the position of the rectangular tube arm body 412 with respect to the arm main body 411 can be changed, depending on the user's body shape, the rectangular tube arm body 412 is arranged along the arm main body 411. This is because the roller pad 43 may be set to be positioned at the upper position. Therefore, in the present embodiment, as shown in FIG. 7B, the arm 41 is first moved forward by a predetermined angle before the seat 32 is returned to the horizontal position. This moving angle is set in advance so as not to interfere with the descending seat 32 even when the rectangular tube arm body 412 is set at the highest position along the arm body 411. In the figure, before the seat 32 is lowered, the user flips up 43a, which is the front side of the roller pad 43, to release the legs so that they are free. In this state, as described above, the roller pad position detection sensor 46 detects that the roller pad 43 is not in a state of sandwiching the user's legs, so the seat 32 is lowered. Operation is not prohibited. Thereafter, as shown in FIG. 7C, the user lowers the seat 32 to make it horizontal. Thereafter, the user gets off the seat 32 and the training is finished.

  Then, after confirming that the arm 41 has been changed to the inclined posture, the user operates the angle adjustment switch 632 (FIG. 1), and the seat bottom 321 is moved as shown in FIG. , Trying to return to a horizontal posture. In this state, the user gets off the seat 32.

  As described above in detail, the leg training device 10 according to the present embodiment has a configuration in which the front end portion of the seating portion 32 is inclined in the vertical direction, and the user is seated when getting into the training device. By keeping the horizontal state, the seating can be facilitated. In particular, it is very useful for an elderly person or a person who needs assistance, because it is not necessary to sit up with the hips raised as in the case of getting into a conventional apparatus, and the user can simply sit on a chair.

  Further, of the pair of roller pads sandwiching the user's legs, the front roller pad can be flipped up from the horizontal position S1 to the upright position S2, and the user placed the legs on the rear roller pad. It is possible to realize the pinching of the leg by simply lowering the roller pad in front of the roller pad. Therefore, for example, in a device in which a pair of roller pads is in a fixed state, the leg portion is inserted into the gap from the side of the roller pad, and the leg portion is slid and moved to an appropriate position. Although necessary and extremely inconvenient, the present apparatus can solve such a problem. This is also intended for the convenience of elderly people and those who require assistance, and has a very useful effect that the user does not have to take an unreasonable posture or action when using the device. is there.

  The present invention is not limited to the above embodiment, and includes the following contents.

  (1) In the above embodiment, the angle after the upward inclination of the seat bottom 321 is set to a constant angle regardless of the user, but the load level for training, the height of the training person, and the like are set in the input device 63. It is also possible to obtain an optimum angle for each user by the control unit 70 by inputting via the control.

  (2) In the above embodiment, the front roller pad 43a adopts the upright posture S2 as the second posture according to the present invention, but in the present invention, the second posture is the upright posture S2. It is not limited to this, and for example, it may be horizontally rotated toward the front to secure a space for getting on and off at the front position of the seating seat 32. You may make it rotate toward.

  (3) In the above embodiment, the user trains the leg by moving the leg against the load given by the device, but the user performs an exercise against the load. Instead, a mode in which the apparatus is moved completely passively may be provided. That is, depending on the user, the leg is not at the stage of sufficient training due to injury etc. In some cases, the movable range of the part should be expanded as much as possible. In such a case, a mode may be provided in which the apparatus side automatically performs a reciprocating motion, while the user entrusts the leg to the motion and performs only the bending and stretching motion of the leg.
