Embodiments for Carrying Out the Invention

[0009] Hereinafter, the present invention will be described through embodiments of the invention, but the invention according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are necessarily essential as means for solving the problems. For clarity of explanation, the following description and drawings have been appropriately omitted and simplified. In each drawing, the same reference numerals are assigned to the same elements, and duplicate explanations are omitted as necessary.

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a view of the foot sculling exercise device as seen from the side. FIG. 2 is a view of the foot sculling exercise device as seen from the front.

[0011] The pedaling exercise device 100 according to this embodiment is an exercise device that can exercise various parts of the user U, such as the legs, abdomen, and buttocks, by the user U performing a pedaling exercise. The pedaling exercise device 100 according to this embodiment will be described with reference to FIGS. 1 and 2. In the following description, the front-rear direction, left-right direction, and up-down direction are directions based on the direction of the user U.

[0012] As shown in FIG. 1, the pedaling exercise device 100 includes a seating part 10, a rotating mechanism 20, a link 30, a crank 40, and an inclined table 50. The seating part 10 is provided behind the rotating mechanism 20. The seating part 10 is configured as, for example, a chair on which the user U sits. The user U performs a pedaling exercise while sitting on the seating part 10.

[0013] Note that the seating part 10 may be provided integrally with the rotating mechanism 20 or may be provided separately. The seating part 10 may be detachably provided on the rotating mechanism 20. For example, the seating part 10 may be a chair in a facility or at home where the user U is. That is, the user U or an assistant may install the seating part 10 behind the rotating mechanism 20.

[0014] In the pedaling exercise device 100, the components attached to the rotating mechanism 20 are symmetric about the left and right. The rotating mechanism 20 rotatably holds the crank 40. For example, a rotating shaft 21 is provided on the rotating mechanism 20. The crank 40 is connected to the rotating shaft 21. The crank 40 rotates around the rotating shaft 21.

[0015] The rotating mechanism 20 may have a load resistor that applies a load to the rotational movement of the crank 40. Note that the rotating mechanism 20 may have a gear or the like for making the load variable.

[0016] Link 30 has a pedal 31 and a sliding wheel 35. A crank 40 is connected to the front end of link 30, and a sliding wheel 35 is connected to the rear end. The crank 40 and the link 30 are rotatably connected. For example, the link 30 is attached to the crank 40 via a bearing or the like.

[0017] The link 30 is attached to the lower surface of the pedal 31 along the longitudinal direction of the pedal. The pedal 31 serves as a step (footrest) on which the user U places the foot FT. The seated user U places the foot FT on the pedal 31. The pedal 31 may be provided with a fixing portion such as a strap for fixing the foot.

[0018] The sliding wheel 35 is attached to the link 30 via a rotating shaft (axle). That is, the link 30 rotatably holds the sliding wheel 35. The sliding wheel 35 serves as a sliding member that slides on the inclined table 50.

[0019] The user U places the foot FT on the pedal 31 and performs a pedaling motion. That is, the user U moves the knee joint and hip joint so as to step on the foot FT. As a result, the crank 40 rotates around the rotation shaft 21. Further, in response to the rotation of the crank 40, the angle between the link 30 and the crank 40 changes. That is, the relative angle of the link 30 with respect to the crank 40 changes according to the rotation angle of the crank 40 (also referred to as the crank angle). Also, the sliding wheel 35 moves in the front-rear direction while being in contact with the inclined surface 52 of the inclined table 50. As a result, in response to the pedaling motion, the crank 40 and the link 30 rotate so that the pedal 31 describes an elliptical orbit.

[0020] Note that the pedal 31, the sliding wheel 35, the link 30, and the crank 40 are respectively provided for the left and right feet FT of the user U. That is, the pedal 31, the sliding wheel 35, the link 30, and the crank 40 are provided on each of the left and right sides of the rotation mechanism 20. The pedal 31, the sliding wheel 35, the link 30, etc. provided on the right side of the rotation mechanism 20 correspond to the right foot FT of the user U. The pedal 31 and the link 30 provided on the left side of the rotation mechanism 20 correspond to the left foot FT of the user U.

[0021] The crank 40 is attached to the rotation axis 21 of the rotation mechanism 20 so as to be out of phase with respect to the left and right feet FT. That is, the rotation angles of the crank 40 for the left foot and the crank 40 for the right foot are shifted by 180°. The user U alternately extends and contracts the left and right feet to perform a foot paddling motion.

[0022] Note that the crank 40 may be attached to the rotation axis 21 of the rotation mechanism 20 so as to be in phase with respect to the left and right feet FT. Also, the foot paddling motion device 100 according to the present embodiment is configured such that the pedal 31 describes an elliptical orbit, but is not limited thereto. For example, the pedal 31 may be configured to describe a circular orbit.

[0023] The inclined table 50 is attached to the rotation mechanism 20. The inclined table 50 has a base frame 51 disposed on the road surface and an inclined surface 52 swingably connected to the base frame 51. The inclined surface 52 is, for example, a rectangular plate-like member. The inclined surface 52 is connected to the rear end of the rotation mechanism 20. The inclined surface 52 is fixed to the rotation mechanism 20 so as to be substantially parallel to the rotation mechanism 20. Therefore, the inclination angle of the inclined surface 52 and the inclination angle of the rotation mechanism 20 are substantially the same. The sliding wheel 35 at the lower end of the link 30 rolls on the inclined surface 52.

[0024] The sliding wheels 35 reciprocate in the front-rear direction in response to the rotational movement of the link 30. While the user U is paddling in the direction of extending the right foot and bending the left foot, the right sliding wheel 35 moves forward and the left sliding wheel 35 moves backward. While the user U is paddling in the direction of extending the left foot and bending the right foot, the left sliding wheel 35 moves forward and the right sliding wheel 35 moves backward.

[0025] By the way, in the conventional paddling exercise device, since the posture of the user is predetermined, only specific parts of the user corresponding to that posture can be exercised.

[0026] On the other hand, the paddling exercise device 100 according to the present embodiment includes a swing mechanism 60 that swings the rotation mechanism 20 in the vertical direction about the end on the seating portion side of the rotation mechanism 20. Thereby, the rotation mechanism 20 can be inclined at an arbitrary inclination angle, and the user U can exercise the part corresponding to the inclination angle by performing a paddling exercise at that inclination angle.

[0027] The swing mechanism 60 according to the present embodiment includes a main body frame 61 and an adjustment bar 62 connected to the main body frame 61. The main body frame 61 is a frame formed in a substantially U shape. The lower side of the U shape is in contact with the road surface. The adjustment bar 62 extends in the left-right direction between two opposing frames of the main body frame 61. The adjustment bar 62 is composed of, for example, two substantially parallel rod-shaped members. The front end of the rotation mechanism 20 is connected to the central portion of the adjustment bar 62.

[0028] Both ends of the adjustment bar 62 are connected to the main body frame 61 by fastening members 63 such as screws. By loosening the fastening member 63, the adjustment bar 62 can be slid in the vertical direction with respect to the main body frame 61. Thereby, the rotation mechanism 20 can be swung in the vertical direction about the end (rear end) on the seating portion side of the rotation mechanism 20. And when the rotation mechanism 20 reaches a desired inclination angle, the fastening member 63 can be tightened and fixed.

[0029] At the center of the adjustment bar 62, a gripping portion 64 that can be gripped by the user U is provided. By loosening the fastening member 63 and lifting the gripping portion 64, the user U can move the adjustment bar 62 upward and increase the inclination of the rotation mechanism 20. Alternatively, by loosening the fastening member 63 and lowering the gripping portion 64, the user U can move the adjustment bar 62 downward and decrease the inclination of the rotation mechanism 20. In this way, by adjusting the height position of the adjustment bar 62, the inclination angle of the rotation mechanism 20 can be easily adjusted.

[0030] A damper device 65 is provided between the base frame 51 and the adjustment bar 62. The damper device 65 is composed of a cylinder filled with gas or liquid, a piston, and the like. The rear end of the damper device 65 is connected to the front end of the base frame 51. The front end of the damper device 65 is connected to the center of the adjustment bar 62.

[0031] When the fastening member 63 is loosened, the gravity of the rotation mechanism 20 acts on the adjustment bar 62, so a large force that pushes the adjustment bar 62 downward acts. The damper device 65 can receive and relieve the force that pushes the adjustment bar 62 downward. Thereby, the user U can smoothly adjust the height position of the adjustment bar 62 and the inclination angle of the rotation mechanism 20 described above.

[0032] As shown in FIG. 3, the damper device 65 can be extended to the maximum length and the rotation mechanism 20 can be set upright. At this time, the angle formed by the base frame 51, the inclined surface 52, and the rotation mechanism 20 is close to a right angle. Thereby, the pedaling exercise device 100 can be compactly stored in a narrow gap or the like in the upright state.

[0033] Next, the operation of the inclination mechanism according to the present embodiment will be described in detail. FIG. 4 is a side view schematically showing the configuration of the pedaling exercise device.

[0034] For example, when the adjustment bar 62 is moved upward to increase the height h of the adjustment bar 62 and the inclination angle θ of the rotation mechanism 20, the joint angle range α around the hip joint and the joint angle range β around the knee joint of the user U when the user U rows with the pedal 31 of the rowing exercise device 100 become larger. In this case, since a greater load is applied to the abdomen and hips of the user U, these parts can be intensively trained.

[0035] On the other hand, when the adjustment bar 62 is moved downward to decrease the height h of the adjustment bar 62 and the inclination angle θ of the rotation mechanism 20, the joint angle range α around the hip joint and the joint angle range β around the knee joint of the user U when the user U rows with the pedal 31 of the rowing exercise device 100 become smaller. In this case, since a greater load is applied to the legs of the user U, the legs can be intensively trained.

[0036] As described above, the rowing exercise device 100 according to the present embodiment includes a seating portion 10 on which the user U sits, a pair of left and right pedals 31 on which the feet FT of the user U are placed, a rotation mechanism 20 that rotates the pedal 31 in an elliptical orbit when the feet FT of the user U step on the pedal 31, and a swing mechanism 60 that swings the rotation mechanism 20 in the vertical direction about the end of the rotation mechanism 20 on the seating portion side. Thereby, the rotation mechanism 20 can be inclined at an arbitrary inclination angle, and the user U can perform rowing exercises at that inclination angle to train various parts according to the inclination angle.

[0037] Although some embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and its equivalent scope.

[0038] For example, the pedaling exercise device 100 according to the above embodiment includes a swing mechanism 60 that swings the rotation mechanism 20 in the vertical direction around the end on the seating part side of the rotation mechanism 20, but is not limited thereto. The pedaling exercise device 100 may include a swing mechanism that swings the seating part 10 in the vertical direction around the end on the rotation mechanism side of the seating part 10. Further, the pedaling exercise device 100 may include both a swing mechanism 60 that swings the rotation mechanism 20 and a swing mechanism that swings the seating part 10.
