In order to describe the present invention in detail, this will be described with reference to the attached drawings. First, the basic structure of the exercise assistance device of the present invention will be described.

As shown in FIGS. 1 and 2, the exercise assisting apparatus of the present invention has a base 10 placed at a fixed position such as a floor, and on the base 10, a seat that supports a buttocks of a user M. A seat support base 20 provided with a portion 21 at the upper end, and a handle post 30 provided with a handle 31 at the upper end that the user M holds by hand as necessary. If the handle 31 is grasped, the position of the upper body of the user M can be stabilized. A foot placement portion 40 having an upper surface as a foot placement surface 40 a is provided at a position between the seat support base 20 and the handle post 30 in the base 10. The foot placement unit 40 is configured to restrict the left and right foot positions by the user M placing the left and right foot soles on the foot placement surface 40a.

The seat support base 20 includes a drive unit 50 that is a seat swing unit 11 that swings the seat unit 21 and a seat unit height change that moves the seat unit 21 and the drive unit 50 up and down relative to the base 10. An elevating mechanism 60 that is means 13 is provided. The configurations of the drive unit 50 and the lifting mechanism unit 60 will be described later.

The drive unit 50 seats the user M in a state where the buttocks are placed on the contact surface 21a of the seat portion 21 and the soles are placed on the foot placement surfaces 40a of the pair of left and right foot placement portions 40 using a drive source. The weight of the user M acting on the leg of the user M is changed by changing the position of the buttocks by swinging the part 21. In other words, in the state where the weight of the user M is distributed and supported between the buttocks and the legs, the weight of the user M supported by the buttocks is increased or decreased by periodically changing the position of the buttocks, and as a result, The acting weight is changed periodically.

Here, when the knee is bent by a predetermined angle, when the ratio of supporting the body weight by the seat portion 21 is reduced, the thigh of the user M is obtained in the same manner as when the knee is bent by performing a squat exercise. The load acting on the thigh increases, and the thigh muscle group can be contracted. That is, when the seat portion 21 is swung by the drive source, the thigh muscle group repeats tension and relaxation due to the passive stepping motion that is not the spontaneous motion of the user M. That is, when the drive unit 50 swings the seat part 21, the thigh muscle group can be exercised and trained.

It is desirable to set the swinging direction of the seat portion 21 so that no shearing force acts on the knee joint. In a state where the user M's buttocks are supported by the contact surface 21a of the seat 21, the user M's feet naturally have a distance on the toe side larger than a distance on the toe side as shown in FIG. The opening angle θ between the two feet can be determined by the position where the foot is placed on the foot placement portion 40. Therefore, by swinging the seat portion 21 in the direction along the center line connecting the heel and toe of each foot when the foot is placed on the footrest portion 40, the knee joint is exercised without applying a shearing force. It becomes possible. That is, when the seat portion 21 moves forward from the rear end position in the swing range, a shearing force is applied to the knee joint by providing a period of moving diagonally right forward and a period of moving diagonally left forward. The weight can be applied to the thighs of the left and right legs without any problems.

An operation display panel 32 is provided at the upper end of the handle post 30. The operation display panel 32 is provided with a display unit 33 composed of a liquid crystal screen for performing a display regarding the amount of exercise, and an operation unit 34 composed of switches for inputting instructions regarding the operation of the drive unit 50 and the lifting mechanism unit 60. Yes.

Next, the structure of the seat support 20 will be described in more detail. As shown in FIG. 3, the seat support base 20 has a hollow support column 22 erected on the base 10, and the lower end of the elevating mechanism 60 is housed inside the support column 22. The elevating mechanism 60 has an elevating base 61 that moves up and down slidably with respect to the support column 22, and a drive unit 50 is mounted on the upper end of the elevating base 61. The drive part 50 is movable with respect to the base 10 together with the seat part 21. The center line of the support column 22 is inclined backward with respect to the vertical direction, and the contact surface 21 a of the seat portion 21 is along the center line of the support column 22 as the elevating base 61 slides in the support column 22. Position adjustment on a straight line.

The elevating base 61 is driven up and down by an elevating drive unit 62 including an elevating motor 63. In addition to the lifting motor 63, the lifting drive unit 62 includes a columnar fixing member 64 that is fixed to the base 10 and a movable member 65 that includes a ball screw that is screwed to the fixing member 64. Thus, the configuration is adopted in which the movable member 65 is rotated relative to the fixed member 64 by rotating the movable member 65. The elevating base 61 is attached to the upper end portion of the movable member 65 and moves up and down as the movable member 65 moves forward and backward with respect to the fixed member 64.

The elevating base 61 includes a pedestal 61a on which the driving unit 50 is mounted, and a pair of guide plates 61b are provided on the lower surface of the pedestal 61a. The upper end portion of the movable member 65 in the elevating drive unit 62 is coupled to the lower surface side of the pedestal 61a. In addition, a roller 61c is attached to the outer surface of each guide plate 61b, and the elevating base 61 is made smooth with respect to the column 22 by guiding the roller 61c with a rail 22a provided inside the column 22. Move. A position sensor 6 that detects the amount of movement of the movable member 65 relative to the fixed member 64 is provided (see FIG. 6), and the rotation of the elevating motor 63 is controlled so that the value detected by the position sensor 6 matches the target value. It has.

A cylindrical lifting cover 66 is attached to the base 61 a of the lifting base 61. The lower end portion of the elevating cover 66 overlaps the outer surface of the support column 22 in the range in which the elevating drive unit 62 expands and contracts. A mechanism cover 67 made of a cloth-like flexible material is also attached to the base 61a of the elevating base 61. The mechanism cover 67 prevents the drive unit 50 from being exposed to the outside by covering the space between the pedestal 61 a and the seat 21.

Next, the structure of the drive unit 50 will be described in more detail with reference to FIGS. The drive unit 50 swings the seat portion 21 together with the pedestal 61a of the elevating base 61. The drive unit 50 includes a pair of front and rear

shaft support plates

51a and 51b erected on the upper surface of the pedestal 61a and

shaft portions

52a and 52b. Worn. The front and

rear shaft portions

52a and 52b are coaxially arranged, and the drive portion 50 rotates about the

shaft portions

52a and 52b, whereby the seat portion 21 coupled to the drive portion 50 is moved in the left-right direction (FIG. 3). Oscillation in the direction indicated by arrow N is possible.

The drive unit 50 includes a pair of front and

rear frame plates

53a and 53b. Both

frame plates

53a and 53b are coupled via a pair of left and right

frame side plates

54a and 54b. Both

frame side plates

54a and 54b are pivotally attached at lower end portions of a front link 55 and a rear link 56 that rotate about a horizontal axis by

shaft portions

55a and 56a. The upper end portion is pivotally attached to the base plate 57 by the

shaft portions

55b and 56b. The upper end portion of the rear link 56 is not directly attached to the base plate 57 but is attached to a bearing plate 57 a fixed to the base plate 57.

The movement range of the base plate 57 is such that the front end portion of the base plate 57 moves on an arc centered on the shaft portion 55a, and the rear end portion of the base plate 57 moves on an arc centered on the shaft portion 56a. It is regulated. Here, the rear link 56 is formed to be longer than the front link 55, and the base plate 57 moves back and forth due to the difference in rotational radius between the front end portion and the rear end portion of the base plate 57. The inclination angle of the upper surface is changed.

Specifically, when the position in FIG. 5 is the rear end position of the movement range in the front-rear direction, the front end portion of the base plate 57 descends relative to the rear end portion with the forward movement, and the upper surface The inclination angle increases. On the contrary, when moving backward from the front end position, the front end portion of the base plate 57 rises relative to the rear end portion, and the inclination angle of the upper surface becomes smaller. Although the movement of the seat portion 21 in the front-rear direction (the direction indicated by the arrow X in FIG. 3) is shown as a linear movement in the figure, the inclination angle in the front-rear direction actually changes. Displacement combined with rotational movement.

A drive motor 71, which is a drive source for swinging the base plate 57 with respect to the base 61a, is held by both

frame side plates

54a and 54b. The drive motor 71 is installed vertically so that the output shaft protrudes upward, and a worm 72 is coupled to the output shaft of the drive motor 71. A first shaft 73 and a second shaft 74 are supported on the

frame side plates

54 a and 54 b, and a worm wheel 75 that meshes with the worm 72 is provided on the first shaft 73. The first shaft 73 is also provided with a gear 76, and the gear 76 is meshed with a gear 77 provided on the second shaft 74.

Eccentric cranks 78 that rotate together with the first shaft 73 are attached to both ends of the first shaft 73, respectively. One end of an arm link 79 is pivotally attached to each eccentric crank 78. The other end portion of each arm link 79 is pivotally attached to a shaft pin 55 c protruding from the left and right of the front link 55.

With the above configuration, when the drive motor 71 rotates and the first shaft 73 rotates, the front link 55 moves back and forth around the shaft portion 55a by the eccentric crank 78 and the arm link 79, and the front portion of the base plate 57 Swings around the shaft portion 55a in the front-rear direction (the direction indicated by the arrow X in FIG. 3). Further, since the rear link 56 rotates about the shaft portion 56a, the base plate 57 changes the inclination angle of the upper surface with the movement in the front-rear direction.

On the other hand, an eccentric pin 74a is provided upright at one end portion of the second shaft 74, and one end portion of the eccentric rod 80 is axially attached to the eccentric pin 74a. The other end of the eccentric rod 80 is pivotably connected to a connecting fitting 81 attached to the pedestal 61a. The eccentric pin 74 a and the eccentric rod 80 may be provided on either the left or right side of the drive unit 50.

With the above configuration, when the second shaft 74 is rotated via the first shaft 73 due to the rotation of the drive motor 71, the eccentric pin 74a and the eccentric rod 80 change the height position of the eccentric pin 74a with respect to the base 61a. As a result, the base plate 57 swings left and right (in the direction indicated by the arrow N in FIG. 3) about the

shaft portions

52a and 52b.

Basically, the drive unit 50 moves the seat 21 to the lower right front and lower front left. However, by appropriately setting the gear ratio of the

gears

76 and 77 and the phase difference between the eccentric crank 78 and the eccentric pin 74a, the movement locus of the seat portion 21 is V-shaped (that is, during one reciprocating movement on the left and right). 2) and a W-shape (ie, a trajectory that reciprocates four times in the left and right directions), and an 8-character shape (ie, between the left and right reciprocations). The trajectory in which the rear end position is biased to the left and right after two reciprocations in front and rear) can be set.

In the exercise assistance apparatus having the above-described configuration, when the user M operates the operation unit 34 provided on the operation display panel 32 to set the height of the seat unit 21 and the content of the exercise and start the swinging operation, The control means 1, which is a control means built in the display panel 32, controls the operation of the elevating motor 63 and the drive motor 71 to reciprocate the seat 21 toward the lower right front and lower left front.

The basic structure of the exercise assistance device of the present invention has been described above. In the following, a more characteristic configuration of the present invention will be described in detail. FIG. 6 is a block diagram showing an electrical configuration of the exercise assisting apparatus of the present invention. The control means 1 that is a control means includes a control circuit 2 to which a command from the operation unit 34 is input, a lift motor control circuit 3 that drives and controls the lift motor 63, and a drive motor control circuit 4 that drives and controls the drive motor 71. And a database 5. The control circuit 2 controls the operation of the lift motor 63 and the drive motor 71 via the lift motor control circuit 3 and the drive motor control circuit 4. Further, the height of the seat portion 21 is detected by the position sensor 6, and the detection result is input to the control circuit 2.

The left and right foot placement sections 40 each incorporate a load sensor 7 that is a load detection means 12 that detects a load applied to the foot placement surface 40a (that is, the stepping force of the user M). The load sensor 7 includes, for example, a slide resistance, a strain gauge, and the like, and can detect how much load is applied to the foot placement surfaces 40a of the left and right foot placement portions 40. The detection results of the left and right load sensors 7 are respectively input to the control circuit 2.

The database 5 stores ideal loads applied to the left and right footrest portions 40 in a form corresponding to the weight of the user M. An ideal load applied to one footrest portion 40 while the seat portion 21 swings is about 30 to 40% of the weight of the user M. A load of + 5% of the ideal load determined according to the weight of the user M is set as an appropriate upper limit value, and a load of -5% of the ideal load is set as a proper lower limit value.

7 shows the control in the case where the height of the seat portion 21 is adjusted according to the detection result of the load sensor 7. As shown in the figure, the load applied to the footrest surface 40a by the load sensor 7 in the left and right footrest portions 40 while the seat portion 21 is swung to cause the user M to perform a passive stepping motion. Is measured (S1). The control circuit 2 compares the detection value input from the left and right load sensors 7 with the appropriate upper limit value and the appropriate lower limit value stored in the database 5 (S2), and the detection value of the load sensor 7 is the appropriate upper limit value. If it falls within the range of the appropriate lower limit, it is determined that the load of the footrest portion 40 is good and the exercise intensity is appropriate (S3), and the height of the seat portion 21 is left unchanged. The rocking motion is continued (S4, S5). Here, as a detection result of the load sensor 7 to be compared with the appropriate upper limit value and the appropriate lower limit value, an average value of a predetermined number of loads detected by the left and right load sensors 7 is used. The predetermined number of times is, for example, about 10 times.

The control circuit 2 continues the swinging motion for a fixed time of about several minutes (S5), and then again measures the load applied to the footrest surface 40a by the load sensor 7 (S1). That is, when the load of the footrest portion 40 is good, the load is measured every few minutes while the seat portion 21 is held at the same height and the swing motion is continued. Since the user M inputs his / her weight in advance using the operation unit 34, the appropriate upper limit value and the appropriate lower limit value are determined based on the input weight and data in the database 5.

On the other hand, when the detection value of the load sensor 7 is below the appropriate lower limit value, it is determined that the load of the footrest portion 40 is too small and the exercise intensity is insufficient (S6), and the lift motor control circuit 3 is used. Then, the lift motor 63 is driven to lower the height of the seat portion 21 by a predetermined level (S7). Immediately after the seat portion 21 is lowered, the load applied to the footrest surface 40a is again measured by the load sensor 7 (S1). That is, load measurement and height change are repeated until the load of the footrest part 40 falls within a favorable range.

When the detected value of the load sensor 7 exceeds the appropriate upper limit value, it is determined that the load of the footrest portion 40 is too large and the exercise intensity is excessive (S8), and the lift motor control circuit 3 is used. The elevator motor 63 is driven to increase the height of the seat 21 by a predetermined level (S9). Immediately after raising the seat portion 21, the load applied to the footrest surface 40a is again measured by the load sensor 7 (S1). That is, load measurement and height change are repeated until the load of the footrest part 40 falls within a favorable range.

The flowchart in FIG. 8 shows control in the case of adjusting the motion speed of the swing motion according to the detection result of the load sensor 7. As shown in the figure, the load applied to the footrest surface 40a by the load sensor 7 in the left and right footrest portions 40 while the seat portion 21 is swung to cause the user M to perform a passive stepping motion. Is measured (S11). The control circuit 2 compares the detected value input from the left and right load sensors 7 with the appropriate upper limit value and the appropriate lower limit value stored in the database 5 (S12), and the detected value of the load sensor 7 is the appropriate upper limit value. If it falls within the range of the appropriate lower limit value, it is determined that the load of the footrest portion 40 is good and the exercise intensity is appropriate (S13), and the swing speed of the seat portion 21 is not changed and is changed as it is. The dynamic motion is continued (S14, S15). Here, as a detection result compared with the appropriate upper limit value and the appropriate lower limit value, an average value of a predetermined number of loads detected by the left and right load sensors 7 is used.

The control circuit 2 continues the swinging motion for a certain time of about several minutes (S15), and then again measures the load applied to the footrest surface 40a by the load sensor 7 (S11). That is, when the load of the footrest portion 40 is good, the load is measured every few minutes while continuing the swing motion at the same speed.

On the other hand, when the detection value of the load sensor 7 is below the appropriate lower limit value, it is determined that the load of the footrest portion 40 is too small and the exercise intensity is insufficient (S16), and the drive motor control circuit 4 is used. Thus, the rotational speed of the drive motor 71 is increased, and the swing speed of the seat portion 21 is increased by a predetermined level (S17). Immediately after raising the rocking speed, the load applied to the footrest surface 40a is again measured by the load sensor 7 (S11). That is, load measurement and speed change are repeated until the load of the footrest unit 40 falls within a favorable range.

If the detection value of the load sensor 7 exceeds the appropriate upper limit value, it is determined that the load of the footrest portion 40 is too large and the exercise intensity is excessive (S18), and the drive motor control circuit 4 is used. The rotational speed of the drive motor 71 is decreased, and the swing speed of the seat portion 21 is decreased by a predetermined step (S19). Immediately after lowering the swing speed, the load applied to the footrest surface 40a is again measured by the load sensor 7 (S11). That is, load measurement and speed change are repeated until the load of the footrest unit 40 falls within a favorable range.

The height control of the seat portion 21 shown in FIG. 7 and the swing speed control of the seat portion 21 shown in FIG. 8 may employ either one of these controls or a combination of both. May be. As control combining the height control of the seat portion 21 and the swing speed control, for example, first, the load applied to the footrest surface 40a is measured after the height of the seat portion 21 is changed. Then, when it is determined that the value does not fall within the favorable range, the control of changing the swing speed of the seat portion 21 is given.

In the example shown in FIG. 7, the rocking speed is changed as the rocking contents of the seat portion 21, but other rocking contents such as the rocking direction and the rocking stroke may be changed. Good. That is, any configuration may be used as long as one or more of the various swing contents of the seat portion 21 such as the swing speed, the swing direction, and the swing stroke are changed based on the detection result of the load sensor 7.

In addition, when changing the height of the seat part 21 and the rocking | fluctuation content of the seat part 21 according to the detection result of the load sensor 7, it is preferable to notify the user M of the change before the change. By this notification, the preparation time for responding to the change can be given to the user M. Examples of the notification means include displaying on the screen of the display unit 33 that a change is to be made.

9 to 12 are examples in which the load detection result detected by using the load sensor 7 is displayed on the screen of the display unit 33 which is the notification means 14. In the example shown in FIG. 9, the load detection results detected by the load sensor 7 are displayed as a time-series bar graph in the order of three months ago, one month ago, and the current value. The load detection result displayed here uses a predetermined average number of loads detected by the left and right load sensors 7. The display form is not limited to the bar graph, and may be another form such as a line graph. The data content to be displayed may be one week before or the day before, or may be one year ago when exercising for a long time.

In the example shown in FIG. 10, the load detection result detected by the load sensor 7 during the current exercise is displayed at the bottom of the screen in a state compared with the standard value. As the load detection result displayed here, an average value of the latest predetermined number of times (for example, the latest 10 times) of the load detected by the left and right load sensors 7 is used. Moreover, the standard value displayed here is a numerical value determined according to the weight of the user M as an ideal load applied to the footrest unit 40. The ideal load applied to one footrest 40 while the seat 21 swings is a load of about 30 to 40% of the weight of the user M, and the user M manipulates his / her own weight in advance. By inputting in the unit 34, the input weight and the data in the database 5 are determined in advance. In the illustrated example, only numerical values are compared and displayed, but may be compared and displayed in other forms such as a bar graph or a line graph.

11 and 12, the comparison result between the load value detected by the load sensor 7 during the current motion and the standard value is graphically displayed in the form of “◎” or “×”. When the load value detected by the load sensor 7 falls within an appropriate range that is ± 5% of the standard value, a figure “◎” is displayed at the center of the display unit 33, and the value falls below or exceeds the appropriate range. Is displayed in the center of the display unit 33.

In the illustrated example, the detection result is notified to the user M only by the graphic symbol “◎” or “×”. For example, the load sensor 7 is used by using the light emitting unit 8 such as an LED installed on the operation display panel 32. Other visual notification means 14 may be employed, such as causing the light emitting unit 8 to emit blue when the load value detected by falls within the appropriate range, and red when outside the proper range. . Further, for example, when the speaker unit 9 installed on the operation display panel 32 is used and the load value detected by the load sensor 7 falls within the appropriate range, a sound is output to the user M to that effect, and the appropriate range is displayed. In the case of the outside, an audible notification means 14 that outputs a sound to the user M may be adopted.

Further, in each of the above examples, the average value of the load detected by the left and right load sensors 7 is used as the load detection result, but the average value of the load detected by the left load sensor 7 (that is, the user M's) The user M may be separately notified of the left leg stepping force) and the average value of the load detected by the right load sensor 7 (that is, the right leg stepping force of the user M). In this case, the time-series display shown in FIG. 9, the comparison display with the standard values shown in FIG. 10, and the graphic displays of “◎” and “x” shown in FIGS. 11 and 12 are displayed separately on the left and right. Further, when the light emitting unit 8 is provided as the visual notification means 14 as described above, the light emitting unit 8 is installed in each of the left and right footrests 40, and the light emitting unit 8 is provided for each of the left and right footrests 40. It is also preferable to control the light emission to blue or red.

In addition to notifying the current stepping force to the user M as described above, the user M may be positively given advice for specifically correcting the current exercise content. In this case, the speaker unit 9 is used as the correction recommendation means 15 that recommends the user M to correct the exercise content. The control circuit 2 outputs a specific motion correction advice from the speaker unit 9 to the user M so as to achieve a predetermined target momentum based on the detection result of the load sensor 7.

For example, when it is estimated from the detection results of the left and right load sensors 7 that the stepping force of the user M is weak, the operation correction advice such as “Let the hips rise slightly and raise the stepping speed” is output as a voice. If the timing of the stepping on the right foot (left foot) of the user M is deviated, the motion correction advice such as “Predict the stepping on the right foot (left foot)” should be output as a voice. Is preferred. Of course, the correction recommendation means 15 is not limited to the voice output means as described above, and other means such as displaying on the screen of the display unit 33 may be adopted.
