Definitions
- the present invention relates to an exercising apparatus that enables a user to take a stepping exercise and a waist twisting exercise simultaneously.
- exercising apparatuses employed for stepping exercises have been recently developed so that every user can take indoor exercise easily.
- These include an exercising apparatus that enables a user to take a stepping exercise and a waist twisting exercise simultaneously (see, for example, Patent Document 1).
- the exercising apparatus that enables the user to take a stepping exercise and a waist twisting exercise simultaneously uses a user's force for taking the stepping exercise.
- the user swings a pair of left and right footboards on which the user gets along the left-right direction in a reciprocating fashion, whereby the user takes a waist twisting exercise.
- Patent Document 1 Japanese Registered Utility Model No. 3060544
- an electric motor in such an exercising apparatus and causing the electric motor to compensate for strength of user's legs with which the user steps on the footboards so as to suppress user's exercise.
- the exercising apparatus including the electric motor, the user can take effective exercise only by naturally moving up and down user's legs. Further, user's burden is light, so that the user can continuously use the apparatus every day. It is, therefore, said that the exercising apparatus with the electric motor is superior to a manual exercising apparatus.
- each of the left and right footboards is structured as a cantilever support beam having an oscillation fulcrum portion provided on a front side thereof. Not only user's weight but also a stepping force during the stepping exercise act on the portion. Due to this, if the exercising apparatus is intended to be simply motorized (driven by the electric motor), then the electric motor driving the oscillation fulcrum portion requires high drive torque and strong power, disadvantageously making the exercising apparatus large in size and high in cost as a whole.
- the present invention has been made in the above-stated circumstances. It is an object of the present invention to provide an exercising apparatus that enables a user to take a stepping exercise and a waist twisting exercise simultaneously while causing an electric motor to compensate for strengths of user's legs by which the user steps without making the apparatus large in size and high in cost.
- the present invention takes the following measures.
- an exercising apparatus comprises:
- left and right footboards provided to be adjacent to each other;
- an oscillation mechanism vertically oscillating the left and right footboards around an oscillation spindle, the oscillation spindle being provided on a front side of each of the left and right footboards with a central axis of the oscillation spindle extending along a left-right direction;
- a swing mechanism swinging the left and right footboards around a swing spindle along the left-right direction in a reciprocating fashion while the left and right footboards are kept adjacent to each other, the swing spindle being provided with a central axis of the swing spindle extending along a vertical direction;
- the exercising apparatus by configuring the exercising apparatus to include the electric motor, a user using the exercising apparatus can simultaneously take a stepping exercise and a waist twisting exercise while receiving assistance from the electric motor and can take effective exercise. Furthermore, since a user's burden is light as compared with use of a manual exercising apparatus, the user can advantageously and continuously use the exercising apparatus every day.
- the swing mechanism may include an installation base plate and a movable base plate, wherein the movable base plate is arranged in parallel to the installation base plate, and is swingable around the swing spindle provided on the installation base plate perpendicularly, and
- the left and right footboards, the oscillation mechanism and the electric motor are provided on the movable base plate.
- the oscillation mechanism includes
- a vertical drive shaft having a central axis of the vertical drive shaft extending along the left-right direction, the vertical drive shaft being fitted into the elongated hole;
- a rotation drive shaft having a central axis of the rotation drive shaft extending along the left-right direction, the vertical drive shaft being attached to the rotation drive shaft in an eccentric state.
- the exercising apparatus can be structured to support both ends of the left and right footboards by the above-stated oscillation spindle and vertical drive shaft, thus making it possible to provide a robust structure.
- a structure around the oscillation spindle can be made simple.
- the oscillation spindle is provided to cross the swing spindle, and is swingable around the swing spindle in an interlocking manner with left-right swing of the movable base plate.
- the oscillation mechanism may include an elastic member provided on each of the lower surfaces of the left and right footboards and urging each of the left and right footboards upward.
- This elastic member always applies an upward urge force to each of the footboards, so that the user can change a state of each of the footboards from a state of being stepped on to a state of moving up with lower force. Further, a load on the electric motor is reduced, so that the exercising apparatus can employ a small-sized electric motor.
- a single electric motor is arranged between the left and right footboards, and the rotation drive shaft protrudes toward both of left and right sides of the single electric motor.
- the swing mechanism may include a guide mechanism provided between the installation base plate and the movable base plate, and holding a gap between the installation base plate and the movable base plate to be constant.
- the swing mechanism may include a power conversion mechanism extracting a left-right swing movement from a vertical movement of each of the footboards generated by the oscillation mechanism, and
- the power conversion mechanism is provided between each of the left and right footboards and the installation base plate.
- the power conversion mechanism may include
- a slider provided on each of the lower surfaces of the left and right footboards, and sliding on an inclined surface of the inclined cam.
- the inclined surface having a height larger as the inclined surface is farther from the swing spindle is formed on the inclined cam.
- the movable base plate includes a pair of left and right notches on both ends of the movable base plate, respectively, the pair of left and right notches being notched toward a center side of the movable base plate, and
- a rail member may be provided on each of the lower surfaces of the footboards and an elongated hole being along the front-rear direction is provided in the rail member.
- a grip rod which faces upward and which the user can grasp is attached to each of the left and right footboards, and that the grip rod is configured to oscillate along the front-rear direction in an interlocking manner with vertical oscillation of the corresponding footboard.
- the user standing on the footboards can simultaneously take a stepping exercise and a waist twisting exercise in a stable attitude of grasping a tip end portion of the grip rod under assistance of the electric motor. It appears to the user that such exercises are skiing (Nordic skiing in particular), so that the user can take a stepping exercise and a waist twisting exercise without feeling bored.
- the swing spindle of the swing mechanism is arranged to be located almost just under a user getting on the left and right footboards in a standing attitude.
- the user getting on the left and right footboards can be given a swing about, for example, a backbone of the user's body. Due to this, the user receiving the swing operation is in a situation of being encouraged to perform a stable waist twisting operation without shifting the center of gravity to largely move the backbone laterally. Therefore, the user can advantageously continue taking exercise comfortably without disturbing a standing attitude (a balance).
- the swing spindle of the swing mechanism may be arranged at a position between the left and right footboards and corresponding to almost a front-rear center of each of the footboards or at a position of almost a front-rear center of the installation base plate and of almost a left-right center of the installation base plate.
- the swing spindle of the swing mechanism is located substantially almost just under the user getting on the left and right footboards in a standing attitude, so that the user can advantageously continue taking exercise comfortably.
- the installation base plate may be formed into a circular shape or a shape approximate to the circular shape in a plan view.
- the oscillation mechanism can include:
- a guide rail provided on each of the lower surfaces of the left and right footboards on an opposite side to the oscillation spindle so as to be along the front-rear direction;
- annular wheel holder provided on a lower portion side of the rail insertion part
- crank wheel held rotatably by the wheel holder while a central axis of the crank wheel is along the left-right direction;
- a rotation drive shaft provided at an eccentric position with the crank wheel while a central axis of the rotation drive shaft is along the left-right direction.
- the swing mechanism can include a power conversion mechanism extracting a left-right swing movement from a vertical movement of each of the footboards generated by the oscillation mechanism, and
- the power conversion mechanism can include a connection rod connecting each of the footboards to the installation base plate, and one end of the connection rod is connected to a side portion of each of the footboards in rear of the oscillation spindle via a first universal joint, and other end of the connection rod is connected to the installation base plate via a second universal joint.
- Each of the first universal joint and the second universal joint may be constituted by a ball joint.
- the power conversion mechanism may be provided to correspond to each of the left and right footboards.
- the power conversion mechanism is provided between the left and right footboards.
- the power conversion mechanism and the other member can avoid interfering with each other, thereby making the entire apparatus compact.
- the single electric motor is arranged between the left and right footboards, and a rotation drive shaft protruding toward both of left and right sides of the single electric motor and a rotation drive shaft protrudes toward both of left and right sides of the single electric motor
- the swing mechanism includes a guide mechanism provided between the installation base plate and the movable base plate and holding a gap between the installation base plate and the movable base plate to be constant.
- the exercising apparatus By using the exercising apparatus according to the present invention, a user can simultaneously take a stepping exercise and a waist twisting exercise while the electric motor compensates for strength of user's legs with which the user steps on the footboards.

Description
- The present invention relates to an exercising apparatus that enables a user to take a stepping exercise and a waist twisting exercise simultaneously.
- Various exercising apparatuses employed for stepping exercises, exercising apparatuses employed for waist twisting exercises and the like have been recently developed so that every user can take indoor exercise easily. These include an exercising apparatus that enables a user to take a stepping exercise and a waist twisting exercise simultaneously (see, for example, Patent Document 1). The exercising apparatus that enables the user to take a stepping exercise and a waist twisting exercise simultaneously uses a user's force for taking the stepping exercise. The user swings a pair of left and right footboards on which the user gets along the left-right direction in a reciprocating fashion, whereby the user takes a waist twisting exercise.
- Patent Document 1: Japanese Registered Utility Model No. 3060544
- It is pointed out that a quantity of exercises of a senior or a woman who intends to lose weight is excessively large if the senior or woman uses the exercising apparatus for the stepping exercise or that for the waist twisting exercise.
- Therefore, it is considered including an electric motor in such an exercising apparatus and causing the electric motor to compensate for strength of user's legs with which the user steps on the footboards so as to suppress user's exercise. With the exercising apparatus including the electric motor, the user can take effective exercise only by naturally moving up and down user's legs. Further, user's burden is light, so that the user can continuously use the apparatus every day. It is, therefore, said that the exercising apparatus with the electric motor is superior to a manual exercising apparatus.
- However, in the exercising apparatus described in the
Patent Document 1, each of the left and right footboards is structured as a cantilever support beam having an oscillation fulcrum portion provided on a front side thereof. Not only user's weight but also a stepping force during the stepping exercise act on the portion. Due to this, if the exercising apparatus is intended to be simply motorized (driven by the electric motor), then the electric motor driving the oscillation fulcrum portion requires high drive torque and strong power, disadvantageously making the exercising apparatus large in size and high in cost as a whole. - The present invention has been made in the above-stated circumstances. It is an object of the present invention to provide an exercising apparatus that enables a user to take a stepping exercise and a waist twisting exercise simultaneously while causing an electric motor to compensate for strengths of user's legs by which the user steps without making the apparatus large in size and high in cost.
- To achieve the above objects, the present invention takes the following measures.
- In other words, an exercising apparatus according to the present application comprises:
- left and right footboards provided to be adjacent to each other;
- an oscillation mechanism vertically oscillating the left and right footboards around an oscillation spindle, the oscillation spindle being provided on a front side of each of the left and right footboards with a central axis of the oscillation spindle extending along a left-right direction;
- a swing mechanism swinging the left and right footboards around a swing spindle along the left-right direction in a reciprocating fashion while the left and right footboards are kept adjacent to each other, the swing spindle being provided with a central axis of the swing spindle extending along a vertical direction; and
- an electric motor simultaneously driving the oscillation mechanism and the swing mechanism.
- In this way, by configuring the exercising apparatus to include the electric motor, a user using the exercising apparatus can simultaneously take a stepping exercise and a waist twisting exercise while receiving assistance from the electric motor and can take effective exercise. Furthermore, since a user's burden is light as compared with use of a manual exercising apparatus, the user can advantageously and continuously use the exercising apparatus every day.
- The swing mechanism may include an installation base plate and a movable base plate, wherein the movable base plate is arranged in parallel to the installation base plate, and is swingable around the swing spindle provided on the installation base plate perpendicularly, and
- the left and right footboards, the oscillation mechanism and the electric motor are provided on the movable base plate.
- Preferably, the oscillation mechanism includes
- an elongated hole provided in rear of and lower surfaces of the left and right footboards so as to be along a front-rear direction;
- a vertical drive shaft having a central axis of the vertical drive shaft extending along the left-right direction, the vertical drive shaft being fitted into the elongated hole; and
- a rotation drive shaft having a central axis of the rotation drive shaft extending along the left-right direction, the vertical drive shaft being attached to the rotation drive shaft in an eccentric state.
- By doing so, the exercising apparatus can be structured to support both ends of the left and right footboards by the above-stated oscillation spindle and vertical drive shaft, thus making it possible to provide a robust structure. Besides, a structure around the oscillation spindle can be made simple.
- Preferably, the oscillation spindle is provided to cross the swing spindle, and is swingable around the swing spindle in an interlocking manner with left-right swing of the movable base plate.
- Furthermore, the oscillation mechanism may include an elastic member provided on each of the lower surfaces of the left and right footboards and urging each of the left and right footboards upward.
- This elastic member always applies an upward urge force to each of the footboards, so that the user can change a state of each of the footboards from a state of being stepped on to a state of moving up with lower force. Further, a load on the electric motor is reduced, so that the exercising apparatus can employ a small-sized electric motor.
- Preferably, a single electric motor is arranged between the left and right footboards, and the rotation drive shaft protrudes toward both of left and right sides of the single electric motor.
- The swing mechanism may include a guide mechanism provided between the installation base plate and the movable base plate, and holding a gap between the installation base plate and the movable base plate to be constant.
- This can stabilize swing operation of a movable base plate.
- The swing mechanism may include a power conversion mechanism extracting a left-right swing movement from a vertical movement of each of the footboards generated by the oscillation mechanism, and
- the power conversion mechanism is provided between each of the left and right footboards and the installation base plate.
- Furthermore, the power conversion mechanism may include
- an inclined cam arranged on the installation base plate along a virtual circular arc centering around the swing spindle; and
- a slider provided on each of the lower surfaces of the left and right footboards, and sliding on an inclined surface of the inclined cam.
- This enables the left-right swing of each footboard to be extracted in an interlocking manner with the vertical oscillation of the each footboard.
- Preferably, the inclined surface having a height larger as the inclined surface is farther from the swing spindle is formed on the inclined cam.
- By so forming, if one of the left and right footboards moves to a lower position, the footboard toward the lower position swings outward of the left-right swing. Accordingly, the user getting on the footboards can make a weight shift naturally and stably according to natural sense.
- Furthermore, preferably, the movable base plate includes a pair of left and right notches on both ends of the movable base plate, respectively, the pair of left and right notches being notched toward a center side of the movable base plate, and
- when the movable base plate swings counterclockwise, the inclined cam provided below the left footboard is located in the left notch, and when the movable base plate swings clockwise, the inclined cam provided below the right footboard is located in the right notch.
- This can ensure that the movable base plate swings in the left-right direction with respect to the installation base plate.
- A rail member may be provided on each of the lower surfaces of the footboards and an elongated hole being along the front-rear direction is provided in the rail member.
- It is also preferable that a grip rod which faces upward and which the user can grasp is attached to each of the left and right footboards, and that the grip rod is configured to oscillate along the front-rear direction in an interlocking manner with vertical oscillation of the corresponding footboard.
- By so configuring, the user standing on the footboards can simultaneously take a stepping exercise and a waist twisting exercise in a stable attitude of grasping a tip end portion of the grip rod under assistance of the electric motor. It appears to the user that such exercises are skiing (Nordic skiing in particular), so that the user can take a stepping exercise and a waist twisting exercise without feeling bored.
- Preferably, the swing spindle of the swing mechanism is arranged to be located almost just under a user getting on the left and right footboards in a standing attitude.
- By doing so, the user getting on the left and right footboards can be given a swing about, for example, a backbone of the user's body. Due to this, the user receiving the swing operation is in a situation of being encouraged to perform a stable waist twisting operation without shifting the center of gravity to largely move the backbone laterally. Therefore, the user can advantageously continue taking exercise comfortably without disturbing a standing attitude (a balance).
- The swing spindle of the swing mechanism may be arranged at a position between the left and right footboards and corresponding to almost a front-rear center of each of the footboards or at a position of almost a front-rear center of the installation base plate and of almost a left-right center of the installation base plate.
- By doing so, similarly to the above, the swing spindle of the swing mechanism is located substantially almost just under the user getting on the left and right footboards in a standing attitude, so that the user can advantageously continue taking exercise comfortably.
- The installation base plate may be formed into a circular shape or a shape approximate to the circular shape in a plan view.
- This can not only improve stability of the entire apparatus but also make the entire apparatus quite compact.
- The oscillation mechanism can include:
- a guide rail provided on each of the lower surfaces of the left and right footboards on an opposite side to the oscillation spindle so as to be along the front-rear direction;
- a rail insertion part slidably fitted into the guide rail;
- an annular wheel holder provided on a lower portion side of the rail insertion part;
- a crank wheel held rotatably by the wheel holder while a central axis of the crank wheel is along the left-right direction; and
- a rotation drive shaft provided at an eccentric position with the crank wheel while a central axis of the rotation drive shaft is along the left-right direction.
- The swing mechanism can include a power conversion mechanism extracting a left-right swing movement from a vertical movement of each of the footboards generated by the oscillation mechanism, and
- the power conversion mechanism can include a connection rod connecting each of the footboards to the installation base plate, and one end of the connection rod is connected to a side portion of each of the footboards in rear of the oscillation spindle via a first universal joint, and other end of the connection rod is connected to the installation base plate via a second universal joint.
- This can ensure that the left-right swing of each footboard is extracted smoothly in an interlocking manner with the vertical oscillation of the footboard.
- Each of the first universal joint and the second universal joint may be constituted by a ball joint.
- The power conversion mechanism may be provided to correspond to each of the left and right footboards.
- By doing so, it is possible to obtain an efficient swing operation.
- Preferably, the power conversion mechanism is provided between the left and right footboards.
- With such an arrangement, the power conversion mechanism and the other member can avoid interfering with each other, thereby making the entire apparatus compact.
- Preferably, the single electric motor is arranged between the left and right footboards, and a rotation drive shaft protruding toward both of left and right sides of the single electric motor and a rotation drive shaft protrudes toward both of left and right sides of the single electric motor, and the swing mechanism includes a guide mechanism provided between the installation base plate and the movable base plate and holding a gap between the installation base plate and the movable base plate to be constant.
- By using the exercising apparatus according to the present invention, a user can simultaneously take a stepping exercise and a waist twisting exercise while the electric motor compensates for strength of user's legs with which the user steps on the footboards. Moreover, the exercising apparatus according to the present invention is small in size and low in cost.

FIGS. 1 to 11 show an exercising apparatus according to a first embodiment of the present invention. - As shown in
FIG. 1 , an exercisingapparatus 1 is used while a user stands on the exercisingapparatus 1. In a following description, a left-right direction on a sheet ofFIG. 2 , a vertical direction on the sheet ofFIG. 2 , and a left-right direction on a sheet ofFIG. 4 will be referred to as a “front-rear direction”, a “vertical direction”, and a “left-right or width direction”, respectively. These coincide with front-rear, left-right, and vertical directions with reference to a direction of the user as shown inFIG. 1 . - As shown in
FIG. 1 , the exercisingapparatus 1 includes a pair of left and right footboards 2 (aleft footboard 2L and aright footboard 2R) provided to be adjacent to each other. - Furthermore, an entire apparatus is covered with a
casing 3 formed out of resin, metal or the like.FIG. 1 shows that, within a range of thiscasing 3, each of thefootboards flexible cover 4 formed out of a rubber sheet, a resin sheet, an artificial leather or the like. - As shown in
FIGS. 2 to 5 , the exercisingapparatus 1 includes anoscillation mechanism 10 and aswing mechanism 11. The exercisingapparatus 1 also includes anelectric motor 12, which drives theoscillation mechanism 10 and theswing mechanism 11 simultaneously. - The
swing mechanism 11 includes an installation base plate (fixed base plate) 14 mounted on a floor, aswing spindle 15 provided on theinstallation base plate 14 with a central axis of theswing spindle 15 extending along the vertical direction, and amovable base plate 16 provided to be swingable along the left-right direction around theswing spindle 15. Theswing spindle 15 is provided in a front portion and at a center in a width direction of theinstallation base plate 14, and designed to pass through a front portion and a center in a width direction of themovable base plate 16. - In the example shown, the
swing spindle 15 is fixed to theinstallation base plate 14 and aspindle cap 17 externally fitted into theswing spindle 15 in a relatively rotatable manner is fixed to themovable base plate 16. - The left and
right footboards oscillation mechanism 10, and theelectric motor 12 are provided on thismovable base plate 16. As a result, if the movable base plate swings around theswing spindle 15, the left andright footboards movable base plate 16 while the left andright footboards - Each of the
installation base plate 14 and themovable base plate 16 is plate-shaped. As shown inFIGS. 2 and 4 , aguide mechanism 18 holding a wheel, a roller, a ball or the like to be rollable is provided between the lowerinstallation base plate 14 and the uppermovable base plate 16. Thisguide mechanism 18 enables themovable base plate 16 to stably swing along the left-right direction while a vertical distance of themovable base plate 16 to theinstallation base plate 14 is kept constant. - As shown in
FIGS. 3 and 7 , aleft notch 20L is formed in a left side portion of themovable base plate 16 and aright notch 20R is formed in a right side portion thereof. Due to this, themovable base plate 16 is formed to be constricted toward the center. - A left
power conversion mechanism 23L is provided between the upperleft footboard 2L and the lowerinstallation base plate 14 to pass into theleft notch 20L formed in themovable base plate 16. A rightpower conversion mechanism 23R is provided between the upperright footboard 2R and the lowerinstallation base plate 14 to pass into theright notch 20R formed in themovable base plate 16. - The left and right
power conversion mechanisms swing mechanism 11 for extracting left and right swing components from operation components for vertically moving the left andright footboards oscillation mechanism 10. These left and rightpower conversion mechanisms - The
left notch 20L is formed to have a size and a constricted shape enough to be able to avoid contact with the leftpower conversion mechanism 23L when themovable base plate 16 swings counterclockwise. Theright notch 20R is formed to have a size and a constricted shape enough to be able to avoid contact with the rightpower conversion mechanism 23R when themovable base plate 16 swings clockwise. - The
oscillation mechanism 10 includes anoscillation spindle 27 supporting the left andright footboards vertical drive shafts 28 circularly moving in a perpendicular plane on vertical movement sides of the left andright footboards shafts 28 kept in the left-right direction, respectively, and rotation driveshafts 29 located at locus centers of circular movements of thevertical drive shafts 28 and circularly rotating thevertical drive shafts 28, respectively. - The
oscillation spindle 27 is arranged on a front side of themovable base plate 16. Theoscillation spindle 27 is arranged on rear sides of thevertical drive shafts 28 and therotation drive shafts 29. Theoscillation spindle 27 is provided to be shared between the left andright footboards vertical drive shafts 28 and therotation drive shafts 29 are provided to correspond to thefootboards - The
oscillation spindle 27 is kept suspended at a predetermined height while both ends of theoscillation spindle 27 are supported betweenbrackets 32 provided outward of width directions of the left andright footboards spindle cap 17 penetrates through an intermediate portion of theoscillation spindle 27, that is, between theleft footboard 2L and theright footboard 2R. Due to this, in a plan view of a portion in which thespindle cap 17 penetrates, theoscillation spindle 27 and theswing spindle 15 of theswing mechanism 10 are arranged to cross each other. - Moreover, a cylindrical spindle-through
portion 33 is fixed to a lower surface of each of the left andright footboards oscillation spindle 27 penetrates into the respective spindle-throughportions 33 in a rotatable state. - The
rotation drive shaft 29 provided to correspond to theleft footboard 2L includes acentral shaft 29 a and anouter shaft 29 b arranged coaxially to be separate from each other so as to face each other from left and right sides of theleft footboard 2L, respectively with theleft footboard 2L held between theshafts central shaft 29 a protrudes downward of theleft footboard 2L from adeceleration part 35 provided between the left andright footboards outer shaft 29 b protrudes downward of theleft footboard 2L from anouter rotor 37 rotatably provided by arotor bracket 36 exceeding and outward of theleft footboard 2L. - The
deceleration part 35 is fixed onto themovable base plate 16 via amotor base 40. Theelectric motor 12 is connected to thisdeceleration part 35. Thedeceleration part 35 decelerates a driven rotation applied from theelectric motor 12 and extracts the decelerated rotation as a rotation of thecentral shaft 29 a of therotation drive shaft 29. Aninner rotor 41 is provided on thiscentral shaft 29 a to be integrally rotatable with thecentral shaft 29. - An
outer rotor 37, which is disc-shaped, is fitted into a circular concave portion provided in arotor bracket 36 without play and rotatably held in therotor bracket 36. Theouter shaft 29 b is provided to penetrate through a center of theouter rotor 37 and a center of therotor bracket 36 within the circular concave portion. Theouter shaft 29 b is rotatable relatively to one of or each of theouter rotor 37 and therotor bracket 36. - The
vertical drive shaft 28 provided to the left footboard 21L is suspended between theouter rotor 37 and theinner rotor 41. Thisvertical drive shaft 28 is connected to theouter rotor 37 and theinner rotor 41 at positions eccentric from rotation centers of theouter rotor 37 and theinner rotor 41 by a same distance in a same direction, respectively. Namely, therotation drive shaft 29 is parallel to thevertical drive shaft 28. - Accordingly, if the
electric motor 12 drives thedeceleration part 35 to rotate theinner rotor 41, thevertical drive shaft 28 moves to draw a circular orbit around therotation drive shaft 29. Theouter rotor 37 thereby rotates to follow thevertical drive shaft 28. - A
rail member 43 is provided on a lower surface of theleft footboard 2L, and thevertical drive shaft 28 penetrates into anelongated hole 44 provided to penetrate therail member 43 along the left-right direction. Thiselongated hole 44 is formed along the front-rear direction. By so forming, only a component by which thevertical drive shaft 28 vertically moves can be extracted from a moving locus on which thevertical drive shaft 28 moves circularly. -
Cam followers 45 are provided in portions of thevertical drive shaft 28 which portions penetrate into the elongated hole 46 of therail member 43 in states of being unmovable along theshaft 28. By so providing, thevertical drive shaft 28 can move smoothly within theelongated hole 44 without play. - The
rotation drive shaft 29 and thevertical drive shaft 28 provided to correspond to theright footboard 2R are almost similar to those provided to correspond to theleft footboard 2L. Therefore, therotation drive shaft 29 and thevertical drive shaft 28 provided to correspond to theright footboard 2R will not be described herein. - It is noted, however, that the
vertical drive shaft 28 provided to correspond to theleft footboard 2L and thevertical drive shaft 28 provided to correspond to theright footboard 2R are deviated from each other in rotational angle by 180°. - An elastic member (a spring body) 48 generating an upward urge force against a force for pressing down each of the left and
right footboards right footboards right footboards - As shown in
FIGS. 2 to 4 , thepower conversion mechanisms swing mechanism 11 includeinclined cams 50 provided on theinstallation base plate 14 andsliders 51 provided separately on the left andright footboards - Each of the
inclined cams 50 is arranged along a virtual circular arc (see reference symbol P shown inFIG. 8 ) on a plane drawn around theswing spindle 15. An inclined surface formed on an upper surface of eachinclined cam 50 is designed to have a direction along the virtual circular arc P and have a larger height as being closer to a central position (a left-right center) of theinstallation base plate 14. - The
left slider 51 is arranged on a tip end of a stay (connection rod) 53 provided to be suspended from theleft footboard 2L and slidable on an inclined surface of the left inclinedcam 50. Likewise, theright slider 51 is arranged on a tip end of astay 53 provided to be suspended from theright footboard 2R and slidable on the inclined surface of the right inclinedcam 50. Each of thesesliders 51 is structured to hold a wheel, a roller, a ball or the like to be rollable. - In each of the left and right
power conversion mechanisms inclined cam 50 and inclination (inclination angle) of the inclined surface of theinclined cam 50 and the positioning and a vertical length of thestay 53 have a following relationship. - Namely, in the left
power conversion mechanism 23L, if thefootboard 2L is raised by theoscillation mechanism 10, theslider 51 operates to get on a higher position of theinclined cam 50. As thefootboard 2L is moved down by theoscillation mechanism 10, theslider 51 operates to slide toward a lower position of theinclined cam 50. During this time, theslider 51 is always kept in a state of abutting on theinclined cam 50. - Likewise, in the right
power conversion mechanism 23R, if thefootboard 2R is raised by theoscillation mechanism 10, theslider 51 operates to get on the higher position of theinclined cam 50. As thefootboard 2R is moved down by theoscillation mechanism 10, theslider 51 operates to slide toward the lower position of theinclined cam 50. During this time, theslider 51 is always kept in a state of abutting on theinclined cam 50. - When the
slider 51 slides from the higher position to the lower position on the inclined surface of theinclined cam 50, a reactive force acts on theslider 51 to push out theslider 51 forward of theinclined cam 50. This reactive force is transmitted to themovable base plate 16 via the left orright footboard oscillation mechanism 10. As a result, a left-right swing force centering around theswing spindle 15 is applied to themovable base plate 16. - Vertical movements of the left and
right footboards oscillation mechanism 10 are alternate with each other along the left-right direction since thevertical drive shafts 28 of the left andright footboards swing mechanism 11, when theslider 51 gets on the higher position of theinclined cam 50 in the leftpower conversion mechanism 23L, theslider 51 slides toward the lower position of theinclined cam 50 in the rightpower conversion mechanism 23R. Conversely, when theslider 51 gets on the higher position of theinclined cam 50 in the rightpower conversion mechanism 23R, theslider 51 slides toward the lower position of theinclined cam 50 in the leftpower conversion mechanism 23L. - As a consequence, when the
right footboard 2R moves down (indicated by “D” inFIGS. 9 and 10 ), themovable base plate 16 swings clockwise and theleft footboard 2L moves up simultaneously (indicated by “U” inFIGS. 9 and 10 ) as shown inFIGS. 9 and 10 . Conversely, when theleft footboard 2L moves down (indicated by “D” inFIGS. 9 and 10 ), themovable base plate 16 swings counterclockwise and theright footboard 2R moves up simultaneously (indicated by “U” inFIGS. 9 and 10 ) (operation in arrow Y directions shown inFIG. 1 ). As repetition of the operation, thefootboards movable base plate 16 continuously swings along the left-right direction in a reciprocating fashion. - In this way, the
oscillation mechanism 10 and theswing mechanism 11 have closely interlocking relationship between them. - As evident from the description given so far, the exercising
apparatus 1 according to the present invention includes theelectric motor 12 and theelectric motor 12 drives theoscillation mechanism 10 to alternately and vertically oscillate the left andright footboards right footboards swing mechanism 11 swings themovable base plate 16 along the left-right direction. - Due to this, the user located on the left and
right footboards apparatus 1 can simultaneously take a stepping exercise (an operation in arrow X directions shown inFIG. 1 ) for vertically moving left and right legs and a waist twisting exercise (an operation in the arrow Y directions shown inFIG. 1 ) for twisting a user's waist alternately left and right. The user can thereby take exercise useful for the user's body such as an aerobic exercise. -
FIGS. 12 to 21C show an exercising apparatus according to a second embodiment of the present invention. - In a following description, a left-right direction on a sheet of
FIG. 13 , a vertical direction on the sheet ofFIG. 13 , and a left-right direction on a sheet ofFIG. 14 will be referred to as a “front-rear direction”, a “vertical direction”, and a “left-right or width direction”, respectively. These coincide with front-rear, left-right, and vertical directions with reference to a direction of a user as shown inFIG. 12 . - Great differences of the exercising
apparatus 1 according to the second embodiment from that according to the first embodiment are anoscillation mechanism 10 and aswing mechanism 11. The remaining configurations are similar to those according to the first embodiment. - Namely, the
swing mechanism 11 includes an installation base plate (fixed base plate) 14 mounted on a floor, a swing spindle 15 (seeFIGS. 15 and 18 ) provided on theinstallation base plate 14 with a central axis of theswing spindle 15 extending along the vertical direction, and amovable base plate 16 provided to be swingable along the left-right direction around theswing spindle 15. - The

guide rail 65, theslider 66, and thecrank wheel 67, two sets ofguide rails 65,sliders 66, and crankwheels 67 are provided in parallel for theleft footboard 2L and two sets ofguide rails 65,sliders 66, and crankwheels 67 are provided in parallel for theright footboard 2R for a reason of making the respective members compact and for a reason of reinforcement. - As shown in
FIGS. 14 , 15, and 17, in the above-statedswing mechanism 11, the leftpower conversion mechanism 23L includes a left connection rod 82 for theleft footboard 2L at a position in rear of theoscillation spindle 27. The left connection rod 82 has one end connected to a firstuniversal joint 80 and the other end connected onto theinstallation base plate 14 via a seconduniversal joint 81. - The first
universal joint 80 forming a connection portion in which theleft footboard 2L is connected to aleft connection rod 82L is formed out of, for example, a ball joint. The firstuniversal joint 80 includes a spherical seat formed on acoupler part 83 provided in a state of protruding laterally rightward of thepivotal bracket 71 provided to protrude downward of theleft footboard 2L, and a ball portion formed on theconnection rod 82L. The spherical seat and the ball portion are spherically jointed with each other, thereby forming a fitted state. - Moreover, the second
universal joint 81 forming a connection portion in which theleft connection rod 82L is connected to theinstallation base plate 14 can be also formed out of a ball joint. This seconduniversal joint 81 includes a spherical seat formed on ahinge base 86 held by asupport base 85 provided on theinstallation base plate 14 in a vertically oscillational state, and a ball portion formed on theconnection rod 82L. The spherical seat and the ball portion are spherically jointed with each other, thereby forming a fitted state. Namely, the two spherical seats are formed on both of left and right sides of onehinge base 86, respectively. - The same thing is almost true for the right
power conversion mechanism 23R. A firstuniversal joint 80 forming a connection portion in which theright footboard 2R is connected to aright connection rod 82R is, for example, a ball joint. The firstuniversal joint 80 includes a spherical seat formed on acoupler part 83 provided in a state of protruding laterally leftward of thepivotal bracket 71 provided to protrude downward of theright footboard 2R, and a ball portion formed on theconnection rod 82R. The spherical seat and the ball portion are spherically jointed with each other, thereby forming a fitted state. - Moreover, a second
universal joint 81 forming a connection portion in which theright connection rod 82R is connected to theinstallation base plate 14 can be also formed out of a ball joint. This seconduniversal joint 81 includes a spherical seat formed on ahinge base 86 held by asupport base 85 provided on theinstallation base plate 14 in a vertically oscillational state, and a ball portion formed on theconnection rod 82R. The spherical seat and the ball portion are spherically jointed with each other, thereby forming a fitted state. Namely, the two spherical seats are formed on both of left and right sides of onehinge base 86, respectively. - Each of the
left connection rod 82L and theright connection rod 82R has a material and a strength so as not to have an elastic or curved deformation only by an external force applied when the left andright footboards universal joint 80 and the second universal joint 81 to follow the vertical oscillation of the left andright footboards oscillation spindle 27 set as a fulcrum is transmitted to the first universal joint 80 side (that is, the left andright footboards left connection rod 82L and theright connection rod 82R are pushed and pulled. - That is, it is assumed that a perpendicular distance between the first
universal joint 80 and the seconduniversal joint 81 while theright footboard 2R is moved up as shown in, for example,FIG. 21A is L, and that thefootboard 2R is moved down to almost a horizontal state as shown inFIG. 21B . A mutual distance at this time is reduced to L−α as shown inFIG. 20B . Due to this, a pressing force resulting from a distance change α to follow a downward movement of thefootboard 2R acts on theright connection rod 82R (with constant length) and thefootboard 2R moves rightward. Eventually, themovable base plate 16 swings clockwise around theswing spindle 15. - As evident from
FIG. 15 , theright connection rod 82R is in a direction inclined rightward and facing outward in a plan view. Due to this, the pressing force moves thefootboard 2R in a right direction and does not act to press thefootboard 2R in a left direction. - Furthermore, it is assumed that the
footboard 2R is moved down as shown inFIG. 21C . A mutual distance at that time is reduced to L−β (β>α) .

right footboard 2R is moved up as shown in FIGS. 21C→21B→21A, a perpendicular distance between the firstuniversal joint 80 and the seconduniversal joint 81 is increased to (L−β)→(L−α)→L. Due to this, a pulling force resulting from such a distance change acts on the right connection rod 82, thefootboard 2R moves in an opposite direction, and themovable base plate 16 swings counterclockwise around theswing spindle 15. Themovable base plate 16 swings around theswing spindle 15 by causing the pressing force and the pulling force to mutually act on the right connection rod 82. - The same thing is true for the
left footboard 2L. Theleft connection rod 82L has a constant length and is in a direction inclined leftward and facing outward in a plan view. Due to this, a pressing force resulting from a downward movement of theleft footboard 2L moves thefootboard 2L in the left direction and does not act to press thefootboard 2L in the right direction. - As stated, eccentricities of the
crank wheels 67 in the left andright footboards left footboard 2L moves down, theright footboard 2R moves up. When theright footboard 2R moves down, theleft footboard 2L moves up. In this way, the left andright footboards left footboard 2L moves down and a pressing force acts on the left connection rode 82L, theright footboard 2R moves up and a pulling force acts on theright connection rod 82R. Conversely, when theright footboard 2R moves down and a pressing force acts on theright connection rod 82R, theleft footboard 2L moves up and a pulling force acts on theleft connection rod 82L. - In this way, when the
left footboard 2L moves down (indicated by “DW” inFIG. 20C ), themovable base plate 16 swings clockwise and theright footboard 2R moves up simultaneously (indicated by “UP” inFIG. 20C ). When theright footboard 2R moves down (indicated by “DW” inFIG. 20A ), themovable base plate 16 swings counterclockwise and theleft footboard 2L moves up simultaneously (indicated by “UP” inFIG. 20A ). As repetition of the operation, thefootboards oscillation spindle 27 set as a fulcrum and themovable base plate 16 continuously swings along the left-right direction around theswing spindle 15.
