Is.

  By the way, since the user sits straddling the seat, when the position of the seat is high from the floor, it may be difficult for some users to get on and off.

In order to make it easy to get on and off such a seat part, it is conceivable to provide a mechanism for lowering the entire seat part to the floor surface to lower the position of the seat part.
JP 2006-122596 A

  However, if a new mechanism for lowering the entire seat portion to the floor surface side is newly provided, there is a problem that the apparatus becomes larger and heavier and more expensive.

  The present invention was made to solve the above problems, and by using an elevating mechanism that elevates or lowers one of the rear part and the front part of the seat part, the apparatus does not increase in size and is inexpensive. It is an object of the present invention to provide an oscillating motion apparatus that makes it easy to get on and off a seat.

In order to solve the above-described problems, the present invention provides a seat portion in which a user sits straddling in a shape simulating a horse's back and heel, a swing mechanism that swings the seat portion, and a rear portion and a front portion of the seat portion. When the user gets on and off the seat in an oscillating-type exercise device provided with an elevating mechanism for raising and lowering either one and a pedestal for positioning the seat at a predetermined height from the floor surface In addition, control means for lowering and tilting one of the rear portion and the front portion of the seat portion in the stopped posture to a predetermined angle by driving the lifting mechanism is provided, while the seat portion is a rear portion of the portion where the user sits straddling Is inclined upwards, the front is inclined forwards, the rear upward part or the front upward part is downwardly inclined to a position substantially horizontal to the floor surface, and the control means is operated by the first switch operation. , Tilting down one of the rear and front of the seat in the stop position The seat portion is detected by the pressure sensor of the seat portion after the user has stepped on the seat portion or descended from the seat portion, and a predetermined time elapses with a timer of the control means. A swing type exercise device is provided that is configured to automatically return to the stop posture .

  According to the present invention, when the user gets on and off the seat portion, the lifting mechanism is driven by the control means, and either one of the rear portion and the front portion of the seat portion in the stopped posture is inclined downward to a predetermined angle. The rear part or the front part of the seat part is at a low position from the floor surface. Therefore, it becomes easy for the user to get on or get off the seat from the rear or front part inclined downward. Moreover, since the existing raising / lowering mechanism which raises / lowers any one of the rear part of a seat part and a front part can be utilized, an apparatus becomes inexpensive, without enlarging and weighting.

Furthermore, by getting the rear rising part or the front rising part of the seat part shaped like a horse's back or heel down to a position substantially horizontal to the floor surface, it is easier to get on and off the seat part.

Further , since the seat portion is tilted downward by the first switch operation according to the user's will, it is possible to prevent inadvertent downward tilt and thus improve safety.

  FIG. 1 is a side view showing the overall configuration of a rocking exercise apparatus 1 according to the present invention. The swing type exercise device 1 includes a seat portion 2 on which a user sits in a shape simulating a horse's back and heel, and a swing mechanism 3 provided in the seat portion 2 to swing the seat portion 2. ing.

  2 is an enlarged side view showing the swing mechanism 3 of the swing type exercise device 1, FIG. 3 is a plan view thereof, and FIG. 4 is a front view thereof. The pedestal 4 to which the seat portion 2 is attached is supported by the movable mount 6 so as to be swingable in the front-rear direction via the front and rear connecting links 5a and 5b.

  As will be described later, the movable base 6 is supported by a base 8 that is inclined so as to be lowered rearward so as to be swingable in the left-right direction.

  Of the front and rear connection links 5 a and 5 b, the front connection link 5 a is provided at both the left and right positions of the base 4, and the rear connection link 5 b is provided at the left and right center position of the base 4. The upper end portion of the front connection link 5a is connected to the upper shaft pin 4a provided at the front end portion of the base 4, and the lower end portion of the front connection link 5a is the lower shaft pin provided at the front end portions of the left and right side plates 16 of the movable base 6. 7a. Further, the upper end portion of the rear connection link 5b is connected to the upper shaft pin 4b provided at the rear end portion of the base 4, and the lower end portion of the rear connection link 5b is provided at the rear end portions of the left and right side plates 16 of the movable mount 6. It is connected to the lower shaft pin 7b. The front and rear connecting links 5a and 5b allow the base 4 to swing back and forth in the front-rear direction.

  Support plates 24 are respectively provided upward on the front and rear portions of the base 8, and connection plates 25 facing the support plate 24 are provided downward on the front and rear portions of the movable mount 6. The support plate 24 and the connecting plate 25 are rotatably connected by front and rear inclined shafts 9 that are inclined so as to be parallel to the base 8 at a central position in the left-right direction. With the front and rear inclined shafts 9, the movable mount 6 can swing back and forth in the left-right direction.

  One electric motor 10 with the output rotation shaft 12 facing upward is attached to the base 8.

  Both end portions of the first shaft 17 are rotatably supported on the left and right side plates 16 of the movable gantry 6, and the first gear 14 is fixed to the first shaft 17. It meshes with the output gear 11 of the shaft 12. Also, an eccentric crank 19 that is eccentrically connected to the end portion of the first shaft 17 and an arm link that is connected to the eccentric crank 19 at one end and connected to a shaft pin 5c provided at the front connecting link 5a. 20 is provided.

  Then, the first gear 14 is rotated by the electric motor 10 via the output gear 11, and the eccentric crank 19 is eccentrically rotated by the first shaft 17 rotated by the first gear 14. Thus, the front connection link 5a reciprocally swings in the front-rear direction via the arm link 20, so that the pedestal 4 connected to the connection links 5a, 5b, that is, the seat portion 2 is swung in the front-rear direction. become.

  Both end portions of the second shaft 18 are rotatably supported on the left and right side plates 16 of the movable mount 6, and a second gear 15 is fixed to the second shaft 18. It meshes with the interlocking gear 22 of the shaft 17.

  An upper end portion 21a of the eccentric rod 21 is rotatably connected to the shaft pin 29 at one end portion (left end portion in the figure) of the second shaft 18, and the lower end portion 21b of the eccentric rod 21 is pivoted. Is pivotally connected to a shaft pin 28 of an L-shaped fitting 27 fixed to the base 8.

  Then, the second shaft 18 rotates through the interlocking gear 22 and the second gear 15 by the rotation of the first shaft 17. As a result, the upper end portion 21a of the eccentric rod 21 moves in an eccentric circle so that the pedestal 4, that is, the seat portion 2 is swung in the left-right direction together with the movable gantry 6 connected to the base 8 by the front and rear inclined shafts 9. It becomes like this.

  FIG. 5 is a perspective view of the elevating mechanism 50, and this elevating mechanism 50 is provided for the rear connection link 5 b of the swing type exercise device 1. That is, the rear connection link 5b is divided into two parts in the vertical direction, and is provided so as to connect the divided parts.

  Specifically, the lifting mechanism 50 includes an electric motor 51, a worm gear 52 fixed to the output rotation shaft 51 a of the electric motor 51, and a worm wheel 53 that meshes with the worm gear 52. Further, a bearing 54 that rotatably supports the worm wheel 53 from above and below, a nut 55 that is fixed to the center hole of the worm wheel 53, and a screw (screw shaft) 56 that is screwed into the nut 55 are provided. The screw 56 is guided so as to move up and down while being prevented from rotating.

  Then, with the bearing 54 mounted in the case 57, the upper end of the screw 56 is connected to the upper part of the rear connection link 5b that is divided into two parts, and the lower end of the screw 56 is below the rear connection link 5b. The guide sleeve 58 is fixed to the portion.

  Next, the operation of the oscillating exercise device 1 will be described collectively.

  The first gear 14 is rotated by the electric motor 10 via the output gear 11, and the eccentric crank 19 is eccentrically rotated by the first shaft 17 rotated by the first gear 14. As a result, the front connection link 5a reciprocally swings in the front-rear direction via the arm link 20, so that the pedestal 4 connected to the connection links 5a, 5b, that is, the seat portion 2, swings in the front-rear direction.

  At the same time, the rotation of the first shaft 17 causes the second shaft 18 to rotate via the interlocking gear 22 and the second gear 15. As a result, the upper end portion 21a of the eccentric rod 21 moves in an eccentric circle so that the pedestal 4, that is, the seat portion 2 is swung in the left-right direction together with the movable gantry 6 connected to the base 8 by the front and rear inclined shafts 9. .

  At this time, the worm wheel 53 is rotated by the electric motor 51 of the lifting mechanism 50 via the worm gear 52, and the nut 55 is also rotated together with the worm wheel 53. As a result, the screw 56 screwed into the nut 55 moves up and down, so that the rear connecting link 5b that is divided into the upper and lower parts is expanded and contracted upward. The pedestal 4 connected to the upper end portion of the front connection link 5a by the upper shaft pin 4a, that is, the seat portion 2, swings in the vertical direction on the rear side around the upper shaft pin 4a of the front end portion.

  Thus, in addition to the seat part 2 being swung in the front-rear direction and the left-right direction, the rear part is swung in the up-down direction. Therefore, for example, when the seat 2 is tilted backward (swings downward), the user takes a forward tilting posture, so that the abdominal muscles are trained and the seat 2 is tilted forward (swings upward). ), The user takes a leaning posture, and his back muscles are trained. As a result, the swinging motion of the seat portion 2 is complicated, so that a great fitness effect can be obtained.

  On the other hand, the elevating mechanism 50 described above is used only for causing the rear portion to swing in the up-down direction during the motion of swinging the seat portion 2 in the front-rear direction and the left-right direction.

  Therefore, an embodiment of the swing type exercise device 1 that makes it easy to get on and off the seat portion 2 by using such a lifting mechanism 50 that lifts and lowers the rear portion of the seat portion 2 will be described.

  As shown by the solid line in FIG. 1, in the stop posture A where the seat portion 2 does not perform a swinging motion, the front portion 2 b tilts forward with respect to the central portion 2 a where the user sits straddling, The rear part 2c is inclined rearwardly. Therefore, when the user gets on the seat 2 or gets off the seat 2, the one leg must be swung upwards larger than the raised front 2b or rear 2c. Thus, in combination with the position of the seat 2 being the position H1 higher than the floor surface 35, it may be difficult for some users to get on and off.

  FIG. 6 is a front view of the operation panel 100 disposed on the upper surface of the front end portion of the seat portion 2. Although not specifically shown, the front end portion of the seat portion 2 has a U-shaped reins (tuna) for the user who straddles the seat portion 2 to grip with the hand so as to straddle the operation panel 100. It is attached.

  In FIG. 6, 101 is a power switch, 102, 103, 104, and 105 change the rotational speed of the electric motors 10 and 51, so that the seat portion 2 can be changed like soft, hardware, leg power, waist power, etc. It is a change-over switch for switching the swinging state.

  106 and 107 are changeover switches for switching the swing speed of the seat portion 2 by changing the rotational speeds of the electric motors 10 and 51 stepwise, such as slowly and quickly. Reference numeral 108 denotes a change-over switch for changing the rearward tilt angle of the seat portion (seat) 2 by changing the rotation amount of the electric motor 51 of the elevating mechanism 50. Reference numeral 109 denotes a boarding / alighting support switch for switching so that boarding / alighting of the seat portion 2 is facilitated.

  A control circuit (control means) 110 such as a microcomputer is incorporated in the operation panel 100, and the rotation speeds of the electric motors 10 and 51 are controlled by switching operations of the switches 101 to 109.

  Then, as shown in FIG. 7, when the user standing on the floor surface 35 pushes the boarding / alighting support switch 109 (first time ... first switch operation) in step S1, the electric motor of the lifting mechanism 50 is obtained in step S2. 51 is driven downward. Thus, in step S3, the rear connecting link 5b that is divided into the upper and lower parts via the worm gear 52, the worm wheel 53, the nut 55, the screw 56, and the like is contracted and moved downward, thereby moving the rear part 2c of the seat part 2 to the lower part. The side is swung downward. Then, the rear portion 2c, which is the rearward rising portion, is inclined downward to a rearward tilting posture B (see the two-dot chain line and arrow a in FIG. 1) that is substantially horizontal with the floor surface 35.

  Thus, the rear portion 2c of the seat portion 2 is inclined downward to a position that is substantially horizontal with the floor surface 35, so that the rear portion 2c becomes a lower position H2 from the floor surface 35, so that the user is inclined downward. Moreover, it becomes easy to get on the seat part 2 by moving to the center part 2a across the rear part 2c.

  Then, after the user straddles the central portion 2a of the seat portion 2 and pushes the boarding / alighting support switch 109 (second time ... second switch operation) in step S4, in step S5, the electric motor of the lifting mechanism 50 is obtained. 51 is driven up. Thus, in step S6, the rear connecting link 5b divided into two parts up and down via the worm gear 52 and the like extends upward and swings upward so that the rear part 2c side of the seat part 2 swings upward (FIG. 1 (see arrow b). And if the rear part 2c which is a rear raising part returns to the stop attitude | position A, the raise drive of the electric motor 51 will be stopped.

  Thereafter, a normal swinging motion or the like can be performed by operating the switch on the operation panel 100.

  In addition, after the normal swing motion or the like is finished, in step S1, the user straddling the seat 2 pushes the boarding / alighting support switch 109 (first time ... first switch operation). As a result, after steps S2 and S3, the rear portion 2c, which is the rearward rising portion, is inclined downward to a rearward inclined posture B (see the two-dot chain line and arrow a in FIG. 1) that is substantially horizontal with the floor surface 35. Therefore, the user can easily get down from the seat portion 2 by moving from the central portion 2a to the rear portion 2c inclined downward.

  Then, after getting off the seat 2, the user pushes the boarding / alighting support switch 109 (second time: second switch operation) in step S4. Then, after steps S5 and 6, the rear portion 2c, which is the rearward rising portion, is swung upward (see arrow b in FIG. 1), and returns to the stop posture A.

  In the case of the swing type exercise device 1 described above, when the user gets on and off the seat 2, the elevator circuit 50 is driven by the control circuit (control means) 110 by the switch operation of the getting on / off support switch 109 and stopped. The rear portion 2c of the seat portion 2 in the posture A is inclined downward to a predetermined angle. Thereby, the rear part 2c of the seat part 2 becomes a position H2 lower than the floor surface 35. Therefore, it becomes easy for the user to get on the seat part 2 from the rear part 2c inclined downward or to get off the seat part 2. Moreover, since the existing raising / lowering mechanism 50 which raises / lowers the rear part 2c of the seat part 2 can be utilized, an apparatus becomes cheap, without enlarging and weighting.

  Further, by getting the rear rising part of the rear part 2c of the seat part 2 downwardly inclined to a position substantially horizontal to the floor surface 35, it is easier to get on and off the seat part 2.

  Furthermore, the seat part 2 is tilted downward by the first operation (first switch) of the boarding / alighting support switch 109 at the will of the user, and the seat part 2 is returned to the stop posture A by the second operation (second switch). . As a result, the seat portion 2 is not inadvertently lowered and tilted, and the seat posture 2 is not inadvertently returned to the stop posture A, so that safety is improved.

  In the above-described embodiment, the rear portion 2c of the seat portion 2 is lowered and inclined by the lifting mechanism 50. However, as shown in FIG. 2b can be inclined downward. The lifting mechanism 50 is provided with respect to the front connection link 5 a of the swing type exercise device 1. That is, the front connection link 5a is divided into two parts in the vertical direction, and is provided so as to connect the divided parts.

  Then, similarly to the above embodiment, when the user pushes the boarding / alighting support switch 109 (first time), the front connection link 5a divided vertically by the lifting mechanism 50 is contracted downward and moved. The front part 2b side of the seat part 2 is swung downward (see arrow a). In this way, the front part 2b, which is the front rising part, is lowered to a forward inclined posture that is substantially horizontal with the floor surface 35, so that the front part 2b is at a position H2 lower than the floor surface 35. Thereby, the user can easily get on the seat portion 2 by moving to the central portion 2a across the front portion 2b inclined downward.

  Then, after the user straddles the central part 2a of the seat part 2 and pushes the getting-on / off support switch 109 (second time), the front connection link 5a divided into two parts by the lifting mechanism 50 is moved upward. By extending and moving, the front side of the seat 2 is swung upward (see arrow b). And the front part 2b which is a front rising part returns to the stop attitude | position A. FIG.

  Further, after the normal swinging motion or the like is finished, the user straddling the seat portion 2 pushes the boarding / alighting support switch 109 (first time), so that the front portion 2b which is the front rising portion is connected to the floor surface 35. It is lowered down to a forward leaning posture that is almost horizontal. Thereby, a user becomes easy to get down from the seat part 2 by moving from the center part 2a to the front part 2b inclined downward. Then, when the user pushes the boarding / alighting support switch 109 (second time) after getting off the seat part 2, the front part 2b, which is the front rising part, returns to the stop posture A.

  In the embodiment, the first switch operation of the getting on / off support switch 109 causes the rear part 2c or the front part 2b of the seat part 2 in the stop posture A to be inclined downward, and the seat part 2 is stopped by the second switch operation. It was controlled to return to the posture A.

  On the other hand, by the first switch operation of the boarding / alighting support switch 109, either the rear part 2c or the front part 2b of the seat part 2 in the stop posture A is inclined downward so that the user gets on the seat part 2 , Or the fact that it has descended from the seat 2 is detected by a pressure sensor or the like of the seat 2. Then, after a predetermined time (for example, 3 to 5 seconds) elapses with the timer of the control circuit 110, the seat portion 2 can be automatically returned to the stop posture A.

  Further, in the stop state, one of the rear part 2c and the front part 2b of the seat part 2 is controlled to always incline downward, and after getting on the seat part 2 or after getting off the seat part 2, The seat portion 2 can be returned to the stop posture A by a push operation.
