Definitions

  • the invention relates to passive exercise equipment which, in the condition that the soles of a user are put on footstools and the buttocks of the user are supported by a seat, drives and moves the seat, thereby changing the weight acting on the user's legs by own weight.
  • the present inventors hit on the idea of making an elastic device intervene between a base part of a footstool and a sole-surmounted part.
  • a body type differs among users, and thereby it disperses magnitude of load added to each footstool by weight difference of leg and so on and results in differences in depressing feel against the sole-surmounted parts. Accordingly, the passive exercise equipment has a problem that constant sense of use cannot be secured.
  • the present invention conceived in light of the foregoing problems, has an objective to provide passive exercise equipment capable of securing constant sense of use so as to avoid variation in depressing feel against sole-surmounted parts irrespective of body type difference among users.
  • the passive exercise equipment of the present invention comprises: a seat 2 configured to rest a user M on the buttocks; right and left footstools 3 configured to rest the right and left soles of the user M sitting on the seat 2 on; and a seat driver 50 configured to change the position of the seat 2 to change load balance added to the seat 2 and the footstools 3 by the user M and thereby to change the user's own weight acting on the legs.
  • Each footstool 3 comprises: a sole-surmounted part 4 which a sole is placed on and meanwhile can be moved up and down; an elastic device 6 configured to bias the sole-surmounted part 4 upward; and a bias adjuster 7 configured to adjust an elastic coefficient of the elastic device 6.
  • an elastic coefficient of each elastic device 6 for biasing a sole-surmounted part 4 upward is adjusted through the bias adjuster 7 in response to body type difference among users.
  • a relatively high elastic coefficient is set for a user M having heavy legs and so on, while a relatively low elastic coefficient is set for a user M having light legs and so on.
  • the passive exercise equipment of the present invention comprises: a body weight input part 8 configured to input body weight of the user M; regulatory drivers 9 configured to drive the bias adjusters 7 to adjust elastic coefficients of the elastic devices 6, respectively; and a controller configured to perform drive control of the regulatory drivers 9 in response to the body weight input though the body weight input part 8.
  • the user M has only to input own body weight through the body weight input part 8, and the controller automatically sets an elastic coefficient of each elastic device 6 based on the body weight. Accordingly, convenient passive exercise equipment 1 can be secured.
  • the passive exercise equipment of the present invention comprises: a body weight detector 10 configured to detect body weight of the sitting user M; regulatory drivers 9 configured to drive the bias adjusters 7 to adjust elastic coefficients of the elastic devices 6, respectively; and a controller configured to perform drive control of the regulatory drivers 9 in response to the body weight detected though the body weight detector 10.
  • the body weight detector 10 detects the user's body weight and the controller automatically sets an elastic coefficient of each elastic device 6 based on the detected body weight. Accordingly, convenient passive exercise equipment 1 can be secured.
  • said elastic device 6 comprises a plurality of spring members 11 arranged between said sole-surmounted part 4 and a base part 5 of said footstool 3.
  • Said plurality of spring members 11 comprises an unconnected spring member 11a having an unconnected end 11a 1 which is not connected to said base part 5 or said sole-surmounted part 4 in a nature state.
  • Said bias adjuster 7 comprises a member switchable between states in which the member is connected to and disconnected from both the unconnected end 11a 1 of said unconnected spring member 11a and said base part 5 or said sole-surmounted part 4.
  • each footstool 3 having a bias adjuster 7 can be simplified, and the production cost of the passive exercise equipment 1 can be reduced.
  • a type of passive exercise equipment 1 in a first embodiment of the present invention has an equipment base 20 put on a fixed position such as a flooring as shown in FIGS. a and 3, and is provided with a seat supporter 21 and a handle post 30 on the equipment base 20.
  • the seat supporter 21 is equipped with a seat 2 for supporting buttocks of a user M on its top edge.
  • the handle post 30 is equipped, on its top edge, with a handle 31 which the user M can grip as need arises.
  • a footstool 3 of which top face is used as a sole-surmounted part 4 is placed at a position between the seat supporter 21 and the handle post 30 in the equipment base 20.
  • Two footstools 3 are laid side-by side in a right-left direction, and the sole-surmounted parts 4 are surmounted by the right and left soles of the user M and thereby regulating the right and left feet placement.
  • the seat supporter 21 is a seat driver 50 for oscillating the seat 2 and an elevating mechanism 60 for moving the seat 2 and the seat driver 50 up and down with respect to the equipment base 20.
  • the configurations of the seat driver 50 and the elevating mechanism 60 are described later.
  • the seat driver 50 oscillates the seat 2 with a drive source to change the position of the buttocks, thereby changing the user's own weight acting on the legs of the user M. That is, when the body weight of the user M is supported with the body weight scattered on the buttocks and legs, the position of the buttocks is changed and thereby the user's own weight supported by the seat 2 or the footstools 3 is increased and decreased so that the weight acting on the legs is changed.
  • Muscle groups in the femoral regions can be contracted. That is, when the seat 2 is oscillated through the drive source, the muscle groups in the femoral regions are repeatedly tensed and relaxed by not active exercise of the user M but passive exercise. In short, the muscle groups in the femoral regions can be exercised by oscillating the seat 2 with the seat driver 50.
  • the oscillation direction should be set so as to prevent shear force from acting on knee joints.
  • the buttocks of the user M is supported by the contact face 2a of the seat 2, when the feet of the user M are in a natural position, the distance between the toe sides is larger than that between the heel sides as shown in FIG. 3 .
  • the opening angle ⁇ 2 between both feet can be determined by the positions of footstool 3 surmounted by the feet. Therefore, the seat 2 is oscillated in a direction along a central line through a heel and a toe of either foot when the feet are placed on the footstools 3, and thereby enabling to exercise without shear force acted on the knee joints.
  • the top face of the seat 2 is substantially included in a horizontal plane, but it is desirable that the contact face 2a contacted with the buttocks of the user M should slope forward and downward in the oscillation direction of the seat 2 because exercise for inducing contraction of the muscle groups in the femoral regions is performed by changing the user's own weight acting on the legs of the user M. That is, it is desirable that, in the front end part of the seat 2, a region for supporting a right buttock of the user M should slope obliquely downward in right front, while a region for supporting a left buttock of the user M should slope obliquely downward in left front. In such configuration, when the seat 2 is moved forward from the rear end position in the oscillation range, the weight acting on the legs can be easily increased and the exercise effect can be enhanced.
  • An operation display device32 is located at the central part of the handle 31 on the top edge of the handle post 30.
  • the operation display device32 performs operator guidance for the seat driver 50 and the elevating mechanism 60, a rough indication about exercise volume, or the like.
  • the user M can stabilize own upper body by gripping the handle 31.
  • the seat supporter 21 has a hollow brace 22 standing on the equipment base 20, and the bottom head of the elevating mechanism 60 is put in the brace 22.
  • the elevating mechanism 60 has an elevating base 61 which can slide with respect to the brace 22 and move up and down, and the seat driver 50 is mounted on the top edge of the elevating base 61. Therefore, the seat driver 50 as well as the seat 2 can move with respect to the equipment base 20.
  • the central line of the brace 22 is a straight line, and sloped backward with respect to a vertical direction (i.e., sloped upward and backward).
  • the position of the contact face 2a of the seat 2 can be adjusted on the straight line along the central line of the brace 22 with respect to the vertical direction by sliding the elevating base 61 inside the brace 22.
  • the position of the contact face 2a of the seat 2 is adjusted in the vertical direction and then at the same time is adjusted in a front-back direction and located more backward as it is located more upward.
  • the central line of the brace 22 has an angle ⁇ of about 75° with the equipment base 20.
  • the elevating base 61 is moved up and down through an elevating driver 62 including a drive motor 63.
  • the elevating driver 62 has a columnar fixed member 64 fixed to the equipment base 20 and a movable member 65 including a ball screw threadably mounted on the fixed member 64.
  • the movable member 65 is adapted to project and retreat with respect to the fixed member 64 by decelerating the rotation of the drive motor 63 to rotate the movable member 65.
  • the elevating base 61 is attached to the top edge of the movable member 65 and moves up and down as the movable member 65 projects and retreats with respect to the fixed member 64.
  • the elevating base 61 has a pedestal 61a on which the seat driver 50 is mounted.
  • a pair of guide panels 61b is provided on the undersurface of the pedestal 61a.
  • the top edge of the movable member 65 in the elevating driver 62 is coupled to the undersurface side of the pedestal 61a.
  • Rollers 61c are also attached on the lateral surface of each guide panel 61b.
  • the rollers 61c are guided by rail parts 22a provided inside the brace 22 and thereby the elevating base 61 can move smoothly with respect to the brace 22.
  • it is provided with a sensor for detecting the projecting and retreating distance of the movable member 65 with respect to the fixed member 64.
  • the rotation of the drive motor 63 is controlled so that a detected value of the sensor agrees with a target value indicated in response to an input from the operation display device 32.
  • the further explanation of the configuration is omitted as it is not gist.
  • a tubular elevating cover 66 is attached to the pedestal 61a of the elevating base 61.
  • the lower part of the elevating cover 66 overlaps with the lateral surface of brace 22 in a range of expansion and contraction of the elevating driver, which prevents the elevating base 61 from being exposed to the outside even if the elevating driver 62 is expanded to be maximized.
  • a mechanism cover 67 formed of fabric flexible material is also attached to the pedestal 61a of the elevating base 61. The mechanism cover 67 covers between the pedestal 61a and the seat 2, and thereby prevents the seat driver 50 from being exposed to the outside.
  • the seat driver 50 is explained with reference to FIGS. 5 and 6 .
  • the seat driver 50 is a mechanism for oscillating the seat 2 as well as the pedestal 61a of the elevating base 61.
  • Pivotal support plates 51a and 51b are stood on the front and the rear of the top face of the pedestal 61a, and the seat driver 50 is pivotally attached to the pivotal support plates 51a and 51b at the pivots 52a and 52b.
  • the pivots 52a and 52b are arranged in front and behind on the same axis.
  • the seat driver 50 rotates around the pivots 52a and 52b, and thereby the seat 2 coupled to the seat driver 50 can oscillate in a right-left direction (the direction indicated by the arrow N in FIG. 4 ).
  • the seat driver 50 includes two frame plates 53a and 53b in front and behind.
  • the frame plates 53a and 53b are coupled through right and left of frame side plates 54a and 54b.
  • the lower ends of the front and rear links 55 and 56 are pivotally attached to the frame side plates 54a and 54b at the pivots 55a and 56a, and thereby rotating around an axis of a right-left direction.
  • the upper ends of the front and rear links 55 and 56 are pivotally attached to a support plate 57 at the pivots 55b and 56b.
  • the upper end of the rear link 56 is pivotally attached not to the support plate 57 directly but to a bearing plate 57a fixed to the support plate 57.
  • the moving range of the support plate 57 is regulated so that the front end part of the support plate 57 can move on a circular arc of which center is the pivot 55a and the rear end part of the support plate 57 can move on a circular arc of which center is the pivot 56a.
  • the rear link 56 is formed to have a longer size than the front link 56, and the front and rear end parts of the support plate 57 are different in a radius of rotation from each other. Thereby, the inclination angle of the top face of the support plate 57 changes as the support plate 57 moves back and forth. Specifically, if the position in FIG.
  • FIG. 6 is the rear end position of the moving range in a front-back direction
  • the front end part of the support plate 57 descends relatively with respect to the rear end part as moving forward and then the inclination angle of the top face becomes large.
  • the front end part of the support plate 57 ascends relatively with respect to the rear end part as moving forward and then the inclination angle of the top face becomes small. That is, the seat 2 can move in a front-back direction (the direction indicated by the arrow X in FIG. 4 ).
  • FIG. 4 shows a rectilinear movement, it actually becomes a composite displacement of a rectilinear movement in the front-back direction and a rotational movement because the inclination angle in the front-back direction is changed.
  • the frame side plates 54a and 54b retain a motor 71 that is a drive source for oscillating the support plate 57 with respect to the pedestal 61a.
  • the motor 71 is vertically placed so that its output axis projects upward.
  • a worm 72 is couple to the output axis of the motor 71.
  • the frame side plates 54a and 54b support first and second shafts 73 and 74 so that they can freely rotate, and the first shaft 73 is provided with a worm wheel 75 engaged with the worm 72.
  • the first shaft 73 is also provided with a gear 76 that engages with a gear 77 supplied to the second shaft 74.

  • an eccentric pin 74a is projected from the one end of the second shaft 74.
  • One end of an eccentric rod 80 is turnably supported by the eccentric pin 74a, and the other end is linked to a connecting fitting 81 attached to the pedestal 61a so that it can oscillate.
  • the eccentric pin 74a and the eccentric rod 80 may supplied to any of the right and left of the seat driver 50.
  • the motor 71 uses a DC brushless motor or the like
  • the drive motor 63 also uses a DC motor.
  • the drive motor 63 is set up in a space surrounded with the frame plates 53a and 53b, the frame side plates 54a and 54b, the pedestal 61a and the support plate 57, while the gears 76 and 77 are also set up in the space. Accordingly, the seat driver 50 is compact.
  • the seat driver 50 basically makes the seat 2 move downward in right front and downward in left front.
  • the seat 2 can have a V-shaped movement locus (reciprocate twice in a front-back direction while reciprocating once in a right-left direction).
  • the seat 2 can have a W-shaped movement locus (reciprocate four times in a front-back direction while reciprocating once in a right-left direction), an 8-shaped movement locus (reciprocate twice in a front-back direction while reciprocating once in a right-left direction, in which rear end positions are biased to the right and left), or the like.
  • the operation display device 32 is operated and thereby directing the drive motor 63 and the motor 71 to drive and stop. That is, the operation display device 32 is provided with an operating portion for directing the motor 71 to drive and stop and directing the rotation speed of the motor 71. Thereby, exercise time and exercise intensity can be specified.
  • a controller (not shown) relates the operating and displaying portions of the operation display device 32 to the operations of the motor 71 and the drive motor 63.
  • the load balance added to the seat 2 and the footstool 3 by the user M is changed, and the weight acting on the legs can be changed.
  • the barycentric position of the user M is shifted forward and thereby increasing the loads acting on the legs including the femoral regions of the user M by own weight.
  • the load by user's own weight mainly acts on the leg at the inclined side of the seat 2. According to these combinations, the user's own weight acting on the legs of the user M is changed and the muscles of the legs can be trained effectively.
  • a bending angle ⁇ 1 of knee requires keeping an appropriate angle.
  • the exercise for keeping an appropriate angle with respect to the bending angle of knee is exercise such that, in squat exercise, the weight acting on femoral regions is changed from the posture knee(s) is previously bent at a predetermined angle. It is desirable that a knee joint agrees with an ankle joint in a vertical direction in order to enhance the loads acting on the femoral regions.
  • the footstool 3 continues supporting the feet of the user M in use, which can be handled by: suitably extending the brace 22 according to leg length of the user M and thereby suitably setting up the vertical position of the seat 2; and stabilizing the position relation between the sole-surmounted parts 4 and the seat 2 which are driven and moved.
  • the vertical position of the seat 2 is set up by operation of the operating portion for elevating the seat 2 in the operation display device 32.

  • the footstool 3 is further provided with elastic device 6 for biasing the sole-surmounted part 4 upward. If the position of the seat 2 is moved through the seat driver 50, the load balance added to the seat 2 and the footstool 3 by the user M is changed, and the user M suitably depress a sole-surmounted part 4 naturally in the teeth of the bias of the elastic device 6. Thereby, the sole-surmounted part 4 vertically moves so as to stabilize the position relation with the seat 2.

  • the passive exercise equipment 1 is devised to secure constant sense of use so as to avoid variation in depressing feel against sole-surmounted parts irrespective of body type difference among users.
  • each footstool 3 is provided with a bias adjuster 7 which can adjust the elastic coefficient of an elastic device 6.
  • the footstool 3 is formed of a plurality of (e.g., three) spring members 11 intervened between a sole-surmounted part 4 and the base part 5 of a footstool 3.
  • the plurality of spring members 11 include a plurality of (e.g., two) unconnected spring members 11a each of which has an unconnected end 11a 1 .
  • the unconnected end 11a 1 is not connected to the base part 5 or the sole-surmounted part 4 (in the embodiment, the sole-surmounted part 5) in a free state in which no external force acts on it.
  • the bias adjuster 7 is formed of a member (a slide member 12 to be described) switchable between states in which the member is connected to and disconnected from both the unconnected ends 11a 1 of the unconnected spring members 11a and the base part 5 or the sole-surmounted part 4 (in the embodiment, both the unconnected ends 11a 1 and the base part 5).
  • each spring member 11 is put side by side at intervals in a front(toe side)-back(heel side) direction and suspended on the undersurface of the sole-surmounted part 4. All upper ends of the spring members 11 are connected to the sole-surmounted part 4. The lower end of the spring member 11 at the front end is connected to the base part 5. But each length of the other spring members 11 is set so that its own lower end is not connected to the base part 5 in a free state. That is, these spring members 11 are the aforementioned unconnected spring members 11a, and the lower ends are the aforementioned unconnected ends 11a 1 .
  • a slide member 12 has substantially the same thickness as the space width between the unconnected end 11a 1 of an unconnected spring member 11a and the top face of a base part 5, and is placed on the top face of the base part 5 through rail-shaped guide parts 13 so that it can slide in a front-back direction.
  • the slide member 12 is formed with an elastic operating part 14 like a handle projecting backward from the footstool 3.
  • the unconnected spring members 11a can be coupled to the sole-surmounted part 4 and the base part 5, if a user M slides the slide member 12 forward with the elastic operating part 14 and thereby makes the unconnected ends 11a 1 of the unconnected spring members 11a touch the top face of the slide member 12. According to the slide member 12, it is possible to select the number of unconnected spring members 11a coupled to the sole-surmounted part 4 and the base part 5 by size of slide in front.
  • the user M selects the number of the spring members 11 coupled to the sole-surmounted part 4 and the base part 5 by handling the slide member 12, the user M can adjust and set the whole elastic coefficient of the elastic device 6. Therefore, by adjusting the elastic coefficient of the elastic device 6 biasing the sole-surmounted part 4 upward through the bias adjuster 7 in accordance with body type difference among users M, it is possible to secure substantially constant sense of use irrespective of body type difference among users M. That is, a relatively high elastic coefficient is set for a user M having heavy legs and so on, while a relatively low elastic coefficient is set for a user M having light legs and so on.
  • a type of passive exercise equipment in a second embodiment is explained. Like kind elements are assigned the same reference numerals as depicted in the first embodiment, and different points from the first embodiment are explained below.
  • FIG. 7 shows the second embodiment that is another example of a footstool 3, and uses extensible base members 15 in place of the aforementioned slide member 12 as a member switchable between states in which the member is connected to and disconnected from both unconnected ends 11a 1 and a base part 5.
  • Each extensible base member 15 includes an upper wall 15a which can touch the unconnected end 11a 1 of an unconnected spring member 11a.
  • the upper wall 15a is placed at the top face of the base part 5 through a parallel linkage, and can be moved up and down.
  • the upper wall 15a is provided with an elastic operating part 14 like a handle projecting outward from the footstool 3 in a right-left direction.
  • an upper wall 15a is provided.
  • the second embodiment can also produce similar results to the first embodiment.
  • the spring members 11 constituting an elastic device 6 are arranged in a linear fashion on a central line of a footstool 3 in a front-back direction.
  • the spring members 11 may be arranged in a voluntary fashion such as a triangular fashion in planar view.
  • one spring member 11 is located at the front part of the footstool 3, and two unconnected spring members 11a are arranged side by side in a right-left direction at the rear part of the footstool 3.
  • Each elastic operating part 14 of the extensible base members 15 is projected backward from the footstool 3.
  • FIG. 9 shows a third embodiment.
  • This embodiment has a body weight input part 8 configured to input the body weight of a user M.
  • Each bias adjuster 7 is provided with a regulatory driver 9 for adjusting the elastic coefficient of an elastic device 6.
  • the controller is configured to perform drive control of each regulatory driver 9 in response to the body weight set through the body weight input part 8.
  • the operation display device 32 can include the body weight input part 8.
  • the regulatory driver 9 may be formed of a drive source 16 such as a motor, a solenoid or the like, and a mechanical section 17 that drives and slides the slide member 12 or drives and moves the extensible base members 15 up and down.
  • a drive source 16 such as a motor, a solenoid or the like
  • a mechanical section 17 that drives and slides the slide member 12 or drives and moves the extensible base members 15 up and down.
  • other configuration can be adapted.
  • a user M has only to input user's own body weight through the body weight input part 8, and the controller automatically sets an elastic coefficient of each elastic device 6 under the bias adjusters 7 through the regulatory drivers 9 based on the input body weight. Therefore, it is possible to avoid troublesome setting of an elastic coefficient of each elastic device 6 through the bias adjusters 7 by hand operation every in-use like the aforementioned embodiments, and secure convenient passive exercise equipment 1.
  • FIG. 10 shows a fourth embodiment.
  • This embodiment has a body weight detector 10 for detecting the body weight of a sitting user M.
  • Each bias adjuster 7 is provided with a regulatory driver 7 for adjusting the elastic coefficient of an elastic device 6.
  • the controller is configured to perform drive control of each regulatory driver 9 in response to the body weight detected with the body weight detector 10.
  • the body weight detector 10 may be formed of weight sensors 10a placed on the seat 2 and two footstools 3. If the weight sensors 10a detect each load from buttocks and soles of a user M, the body weight of the user M can be detected from sum of them.
  • the body weight detector 10 detects the body weight of the user M and the controller automatically sets an elastic coefficient of each elastic device 6 under the bias adjusters 7 through the regulatory drivers 9 based on the detected body weight. Therefore, it is possible to avoid troublesome setting of an elastic coefficient of each elastic device 6 through the bias adjusters 7 by hand operation every in-use like the aforementioned embodiments, and secure convenient passive exercise equipment 1.
