Exercise equipment

The present invention relates to an exercise device that allows a user to perform a passive movement by driving a footrest unit on which the left and right soles are placed.

Conventionally, there has been proposed an exercise device that allows a user to perform a passive movement by driving a footrest portion on which the user puts the left and right soles. For example, Japanese Patent Laid-Open No. 10-55131 discloses an exercise device that enables walking training. However, this conventional exercise device has a very complicated mechanism for driving the footrest. For this reason, there is a problem of increasing the size and cost.

The present invention has been made in order to solve the above-described problems, and an exercise device capable of driving a footrest portion to allow a user to perform passive movement is compact and inexpensive. The purpose is to provide.

The exercise device of the present invention for solving the above problems includes a footrest 1 on which a user puts the soles of both feet, and swinging means 5 for swinging the footrest 1 so as to be alternately tilted left and right. The left and right stepper portions 6 formed by providing portions where the left and right soles of the footrest 1 touch each other are movable up and down, and the left and right stepper portions 6 are moved up and down as the footrest 1 tilts left and right. Stepper driving means 9 is provided.

In the exercise device of the present invention having the above-described configuration, when the user swings the footrest 1 left and right in a posture in which a part of the left and right soles is placed on the stepper portion 6, the left and right stepper portions are accordingly accompanied. 6 moves up and down. The user is swung from side to side and the toes are bent back and bent, and the balance of the whole body is forcibly broken. When the user tries to balance against this, the sense of balance and muscles are effectively trained. And since a complicated structure is not required in order to implement | achieve such a passive motion, an exercise device can be provided as a compact and cheap thing.

In order to describe the present invention in detail, this will be described with reference to the attached drawings. In addition, each direction such as front / rear / left / right used in the text is based on a direction viewed from the user with both feet placed on the footrest 1.

1 to 6 show an example of an exercise device according to an embodiment of the present invention. As shown schematically in FIG. 1 as a whole, the exercise device of the present invention has a flat footrest 1 on which a user (not shown) can place the soles of both feet, and the footrest 1 as a center. A motor 2 that rotates left and right around the axis A (in the direction of the arrow in FIG. 1), a base 3 that supports the footrest 1 and the motor 2, and a pair of left and right contacts that are erected on the base 3 And a member 4.

The central axis A, which is the center of rotation of the footrest 1, is an axis that extends from the top to the rear in the lateral direction at the center position in the left-right direction when viewed from above. Therefore, when the motor 2 is driven to reciprocate the footrest 1 within a predetermined range, the footrest 1 repeats alternately a posture inclined to the left side and a posture inclined to the right side. That is, the motor 2 for reciprocatingly rotating the footrest 1 is a swinging means 5 that swings the footrest 1 so as to be alternately tilted to the left and right.

The right rear portion and the left rear portion of the footrest 1 are provided so as to be movable up and down with respect to the other portions of the footrest 1. In the following, the right rear portion and the left rear portion of the footrest 1 that can be moved up and down are referred to as left and right stepper portions 6, and portions that are driven by the motor 2 except for the stepper portion 6 of the footrest 1. The footrest main body 7 is used.

The stepper portion 6 is in a position where the rear heel portion of the sole of the user hits, and is connected to the footrest base body 7 so as to be rotatable around the central axis B via the hinge portion 8. Yes. The hinge portion 8 is connected to the front end edge of the stepper portion 6. Further, the central axis B has the left-right direction as the axial direction.

Therefore, when the stepper unit 6 is rotated around the central axis B so as to lower the rear side, the stepper unit 6 is lowered relative to the footrest base body 7 as a whole. Further, when the stepper portion 6 is rotated around the central axis B so as to raise the rear portion side, the stepper portion 6 moves up with respect to the footrest base body 7 as a whole.

The pair of left and right contact members 4 erected on the base portion 3 are in positions that face the corresponding stepper portions 6 in a one-to-one direction in the vertical direction. The height of the contact member 4 is such that when the footrest base body 7 of the footrest 1 is in the reference posture, the stepper portion 6 supported by the upper end of the contact member 4 being in contact with the footrest base body 7 is flush with the footrest base body 7. (See FIG. 2). Here, the reference posture is a posture in which the footrest base body 7 is horizontal in the left-right direction.

In order to perform passive motion using the exercise device having the above-described configuration, the user first places the left and right soles on the footrest 1 in the standard posture so that the heel portion is on the stepper unit 6 and stands upright. Keep posture. At this time, the left and right stepper portions 6 are supported by the lower contact member 4 and maintain a horizontal posture. Here, when the operation unit (not shown) is operated to reciprocately rotate the motor 2, the footrest 1 reciprocates around the central axis A, and alternately alternates between a posture inclined to the right side and a posture inclined to the left side. Repeat.

As shown in FIG. 3, when the footrest 1 is inclined to the right, the right stepper portion 6 that presses against the lower contact member 4 by the weight of the user moves upward with respect to the footrest main body 7. (See FIG. 4). Further, the left stepper portion 6 that presses against the lower contact member 4 by its own weight rotates so as to move downward with respect to the footrest base body 7. Similarly, when the footrest 1 is inclined to the left, the right stepper portion 6 rotates so as to move downward with respect to the footrest main body 7, and the left stepper portion 6 moves relative to the footrest main body 7. Turn to move upward.

That is, the pair of left and right contact members 4 supported by pressing against the left and right stepper portions 6 from below serves as stepper driving means 9 that moves the left and right stepper portions 6 up and down as the footrest 1 tilts left and right. . The stepper driving means 9 is for positioning the left and right stepper portions 6 at the same height as the footrest main body 7 when in the reference posture. When the footrest 1 swings, the stepper driving means 9 moves to the footrest main body 7. On the other hand, one of the left and right stepper portions 6 is raised and the other is lowered.

The user swings the entire footrest 1 to the left and right while standing on the footrest 1 and further moves the left and right stepper sections 6 alternately up and down. Against this, when the user balances the whole body, the sense of balance and muscles are effectively trained. When the stepper unit 6 moves upward, the leg of the user who puts the heel portion on the stepper unit 6 is bent back. When the stepper unit 6 moves downward, the foot of the user who puts the heel portion on the stepper unit 6 is bent down. That is, the user's left and right feet alternate between dorsiflexion and bottom flexion.

Note that the direction of the user during exercise may be reversed. When the front and rear are reversed, the toe portions of the left and right feet of the user hit the stepper portion 6. When the stepper unit 6 moves upward, the foot of the user who puts the toe portion on the stepper unit 6 becomes dorsiflexed, and when the stepper unit 6 moves downward, the user uses the toe portion on the stepper unit 6 The person's feet are bent down.

Also, the user may be in a sitting position. At this time, the user can cause both feet to perform the same dynamic motion in a posture in which the user is seated on a seat (not shown) and both feet are placed on the footrest 1.

Also, by appropriately setting the height of the contact member 4, the presence or absence and degree of dorsiflexion and bottom flexion of both left and right feet can be freely set. For example, when the height of the right contact member 4 is set lower than in the case of FIGS. 1 to 4, and the footrest base body 7 is in the reference posture, the right stepper portion 6 is positioned below the footrest base body 7. However, when the footrest base body 7 is most inclined to the right side, the right foot is set not to bend back if the right stepper portion 6 is provided so as to be flush with the footrest base body 7. The presence / absence and setting of such dorsiflexion and bottom flexion can be independently performed on the left and right. Note that the same effect can be obtained by changing the height of the footrest 1 instead of changing the height of the contact member 4.

The contact member 4 may be an elastic member using a spring or the like. In this case, the load on the motor 2 when returning from the displaced state can be reduced.

7 to 10 show other examples of the exercise device according to the embodiment of the present invention. The exercise device of another example is different from the exercise device of the above example only in the configuration of the hinge portion 8. In the following, the same components as those of the example exercise apparatus are denoted by the same reference numerals, detailed description thereof is omitted, and the configuration of the hinge portion 8 different from the example exercise apparatus will be described in detail.

By the way, in the exercise apparatus of an example, the hinge part 8 is installed in the direction orthogonal to the central axis A of the footrest 1 (see FIG. 1), and the center where the stepper portion 6 rotates with respect to the footrest main body 7. The axis B and the central axis A on which the footrest main body 7 is driven to rotate are orthogonal to each other. On the other hand, in the exercise device of another example, the hinge portion 8 is installed in a direction parallel to the central axis A of the footrest 1, and the central axis B where the stepper portion 6 rotates with respect to the footrest main body 7. And the central axis A on which the footrest main body 7 is rotationally driven are parallel to each other. The hinge portion 8 is connected to the inner edge of the stepper portion 6. Further, the central axis B has the front-rear direction as the axial direction.

In this way, the exercise device of the other example realizes bottom flexion and dorsiflexion of both left and right feet, and at the same time, turns both left and right feet inside out and out. For example, the right stepper unit 6 located at the same height as the footrest main body 7 when in the reference posture (see FIGS. 7 and 8) is moved to the footrest main body 7 as the footrest 1 tilts to the right. On the other hand, it is displaced upward and is inclined from the outside to the inside (see FIGS. 9 and 10). That is, the right foot on which the heel portion is placed on the stepper portion 6 on the right side is turned upside down at the same time as being bent back. At this time, the left foot on which the heel portion is placed on the left stepper portion 6 is bent back at the same time as it is bent.

Furthermore, if the position of the hinge portion 8 and the height of the contact member 4 are appropriately set, the degree and combination of dorsiflexion, bottom flexion, inversion, and inversion of the foot with the heel or toe portion placed on the stepper portion 6 It can be set appropriately.
