BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
<Description of the overall configuration of the physical exercise device 1>
FIG. 1 is a perspective view showing an example of the overall configuration of a physical exercise apparatus 1 to which this embodiment is applied.
As shown, the physical exercise apparatus 1 of this embodiment includes a step 10 on which the user sits, an operation panel 20 for operating the physical exercise apparatus 1, and a power connection unit 30 for connecting a power source for operating the physical exercise apparatus 1. , a USB connector 40 for connecting a USB (Universal Serial Bus) device, a vibration generator 50 for generating vibration, a control unit 60 for controlling the physical exercise device 1, and a housing 70 containing the vibration generator 50. and a rear cover 80 connected to the housing 70 for placing the physical exercise apparatus 1 on the floor or the like. In addition, in FIG. 1, the longitudinal direction of the body exercise apparatus 1 is defined as the "width direction".

The step 10 is an example of a footrest portion, and transmits vibration generated by the vibration generating portion 50 to the user. For example, the user places both feet on the step 10 in a standing state, thereby performing an action to keep the posture on the step 10 . As a result, the user can strengthen the balance of the body including the trunk, and can exercise.
Further, the step 10 does not vibrate much near the central portion in the width direction, but vibrates greatly in the vertical direction toward the end portions in the width direction. This vibration may be hereinafter referred to as "vertical vibration". In FIG. 1, the direction of vertical vibration is indicated by a double arrow. It can also be said that the step 10 vibrates vertically in the width direction with the central portion as a fulcrum. Therefore, the user can change the magnitude of vibration depending on the position where the user stands on the step 10 . That is, for example, if both feet are placed near both ends of the step 10 in the width direction, a large vibration can be received from the step 10 . On the other hand, if the positions on which both feet are placed are changed from the both ends toward the center, the vibration received from the step 10 becomes smaller toward the center. Therefore, the user can adjust the vibration received from the step 10 depending on the position where the user stands on the step 10 .
In addition to the vertical vibration, the step 10 can give the user a finer vibration than the vertical vibration. In this embodiment, this vibration may be hereinafter referred to as "fine vibration".
The operation panel 20 functions as an interface for the user to operate the physical exercise apparatus 1 . Various buttons are arranged on the operation panel 20 , and the user can select an operation of the physical exercise apparatus 1 by operating these buttons. The operation panel 20 is provided with a power switch, for example, by which the physical exercise apparatus 1 can be turned ON/OFF. Further, the operation panel 20 is provided with a button for adjusting the speed of vibration, and the speed of vibration can be changed by operating this button. That is, the vibration can be sped up or slowed down. At this time, the user can change the speed of vibration step by step. That is, the user operates buttons on the operation panel 20 to input an integer value of 1 to 20, for example. Thereby, the user can change the speed of vibration stepwise in 20 steps.

Furthermore, the operation panel 20 is provided with operation mode buttons, which allow the user to select the operation mode of the physical exercise apparatus 1 . For example, a program mode can be set as the operation mode, and the physical exercise apparatus 1 can be operated according to a predetermined program. Furthermore, the operation panel 20 is provided with a timer button, and the time for operating the physical exercise apparatus 1 can be set. On the operation panel 20, ON/OFF and volume of music can be set when outputting music, which will be described later. Further, the operation panel 20 is provided with a display section, which displays power ON/OFF, vibration speed, operation mode, timer remaining time, volume, and the like.

The power supply connection unit 30 is a unit for connecting a power supply. In this case, an AC commercial power supply can be used as the power supply. Since the power supplied from the commercial power supply is used by the vibration generating section 50, the power supply connection unit 30 converts AC to DC and steps down the voltage to an appropriate voltage. Further, in this embodiment, the power supply connection unit 30 includes a power connector 31 for connecting a commercial power supply. Further, the power supply connection unit 30 includes a main power switch 32 for turning ON/OFF the power supplied from the commercial power supply.

The USB connector 40 receives data to be input to the physical exercise apparatus 1 via a USB device. In this case, the USB device is, for example, a USB memory, a storage such as a HDD (Hard Disk Drive), a music player, or the like. Data to be input includes music data. That is, the user inputs music data to the USB device in advance. Then, a USB device is connected to the USB connector, and the music data is taken into the physical exercise device 1. - 特許庁Then, the physical exercise apparatus 1 outputs music from a speaker or the like (not shown) based on the music data captured by the user. Thereby, the user can use the physical exercise apparatus 1 while enjoying his or her favorite music.

The vibration generator 50 generates vibrations to be given to the user in step 10 . The vibration generator 50 is an example of vibration means.
FIG. 2 is a diagram showing the vibration generator 50. As shown in FIG.
FIG. 2 is a view when viewed from direction II in FIG. 1 with the back cover 80 removed.
As shown in the figure, the vibration generating section 50 includes an electric motor 51 that generates a rotational force, a conversion section 52 that converts the rotational force of the electric motor 51 into vertical vibration, and a fine vibration section 53 that generates fine vibration. Prepare. In FIG. 2, the control unit 60 is also illustrated together.

The electric motor 51 rotates the rotating shaft 511 by electric power from the power supply connection unit 30 and generates a rotating force. Further, the electric motor 51 changes the number of revolutions according to the speed of vibration set by the user on the operation panel 20 . That is, if the user sets the vibration speed slower, the electric motor 51 rotates slower, and if the user sets the vibration speed faster, the electric motor 51 rotates faster.

The conversion unit 52 includes pulleys 521 and 522 , a belt 523 , a rotating shaft 524 , an eccentric pulley 525 and a swing arm 526 .
The pulley 521 is fitted on the rotating shaft 511 of the electric motor 51 , and the pulley 522 is fitted on the rotating shaft 524 . A belt 523 is wound around the pulley 521 and the pulley 522 . Therefore, when the rotating shaft 511 rotates, the rotating force is transmitted to the pulley 521, the belt 523, and the pulley 522 in this order, and the rotating shaft 524 rotates.
An eccentric pulley 525 is fitted to the rotating shaft 524 in addition to the pulley 522 . Therefore, when the rotating shaft 524 rotates, the eccentric pulley 525 rotates according to the rotation of the rotating shaft 524 . Since the rotating shaft 524 does not penetrate the center of the eccentric pulley 525 but penetrates it at a position off the center, the eccentric pulley 525 rotates eccentrically.

Since the swing arm 526 is connected to the eccentric pulley 525, it reciprocates vertically as the eccentric pulley 525 rotates eccentrically. The swing arm 526 has a rotating shaft 730 (see FIG. 3), and the rotating shaft 730 is fixed. Therefore, the swing arm 526 moves up and down around the rotating shaft 730 except for the rotating shaft 730 .
A further step 10 connects on the swing arm 526 . Therefore, the step 10 performs the vertical vibration described above in accordance with the vertical movement of the swing arm 526 .

The fine vibrator 53 is a so-called vibrator, and has, for example, a structure in which an eccentric weight whose center of gravity is offset is attached to the shaft of a motor. When the motor is rotated, the rotating shaft of the motor vibrates, and the resulting vibration causes minute vibrations. A motor and an eccentric weight are built in the fine vibration part 53 and are not illustrated here.

Returning to FIG. 1 , the control unit 60 controls the operations of the electric motor 51 and the fine vibration section 53 . That is, the control unit 60 controls ON/OFF of the electric motor 51 and the fine vibrating section 53 and the speed of rotation of the electric motor 51 . The rotation speed, which is the speed of rotation of the electric motor 51 , is controlled by the control unit 60 by changing the current value of the electric current supplied to the electric motor 51 . By controlling ON/OFF of the electric motor 51 and the fine vibrating portion 53, at least one of the electric motor 51 and the fine vibrating portion 53 generates vibration. Therefore, by combining the vibrations generated from the electric motor 51 and the fine vibrating section 53, vibrations in various patterns can be given to the user.

The control unit 60 detects whether vibration is transmitted to the user. Then, the control unit 60 controls the vibration generating section 50 so as to change the vibration depending on whether or not the vibration is transmitted to the user.

The housing 70 incorporates the vibration generator 50 . As a result, the vibration generator 50 is isolated from the user, and the safety of the user is ensured.
The housing 70 is held by the rear cover 80 . The back cover 80 has a plurality of legs 81 . Such legs 81 allow the physical exercise apparatus 1 to be installed more stably on the floor or the like.
The housing 70 and back cover 80 are examples of changing means, and the leg portion 81 is an example of a support base.

<Case 70>
Next, the housing 70 is described.
3A and 3B are diagrams for explaining the configuration of the housing 70, in which FIG. 3A is a perspective view and FIG. 3B is a side view.
As shown in FIG. 3A, the housing 70 includes an upper housing 710 that vibrates vertically, a lower housing 720 that holds the upper housing 710, and the upper housing 710 and the lower housing 720. and a connecting rotating shaft 730 . The rotating shaft 730 is positioned substantially at the center in the width direction and extends in the front-rear direction.
Upper housing 710 is attached to step 10 (see FIG. 1) described above.

The upper housing 710 has the aforementioned swing arm 526 (see FIG. 2). The lower housing 720 has the above-described electric motor 51, pulleys 521, 522, belt 523, rotating shaft 524, and the like (see FIG. 2).
With such a configuration, the upper housing 710 vibrates vertically with respect to the lower housing 720 by the driving force of the electric motor 51 . Although the above-described fine vibrating portion 53 (see FIG. 2) is attached to the upper housing 710, a configuration without the fine vibrating portion 53 may be adopted.

The lower housing 720 has a rotating shaft 721 rotatably connected to the back cover 80 and four movable parts 722 whose lower ends are in contact with the inner surface of the back cover 80 .
The rotating shaft 721 is held at a predetermined height H from the floor FL by the back cover 80 . The rotating shaft 721 is positioned substantially at the center in the front-rear direction and extends in the width direction. The rotation axis 721 and the rotation axis 730 are in a positional relationship in which imaginary extension lines are substantially perpendicular to each other.
A load applied to the lower housing 720 is transmitted to the back cover 80 via the rotating shaft 721 . Further, as shown in FIG. 4, which will be described later, the load applied to the lower housing 720 is transmitted to the back cover 80 via the movable portion 722, and transmitted to the leg portion 81 placed on the floor FL. .

In the state of the movable portion 722 shown in FIG. 3B, the dimension from the floor surface FL to the lower surface of the lower housing 720 is the length L on either side in the front-rear direction.
Each of the four movable parts 722 has a compression coil spring 723 and has a variable vertical length. The compression coil spring 723 is an example of an elastic member.

FIG. 4 is a cross-sectional view illustrating the movable portion 722 of the lower housing 720. As shown in FIG.
As shown in FIG. 4 , the movable portion 722 is formed at a position corresponding to the leg portion 81 of the back cover 80 . The compression coil spring 723 held by the movable portion 722 has its upper end attached to a convex portion 724 formed on the lower housing 720 and its lower end attached to a convex portion 81 a formed on the leg portion 81 of the back cover 80 . be done.
As a result, when the lower housing 720 rotates with respect to the back cover 80, the biasing force of the compression coil spring 723 is input, and the rotation is suppressed.

FIG. 5 is a diagram for explaining the behavior of the housing 70 with respect to the back cover 80, and is a left side view seen from the direction of arrow A in FIG. (a) shows a state of tilting forward, and (b) shows a state of tilting backward. In both cases, illustration of the back cover 80 is omitted. Further, among the four movable portions 722, the front side may be referred to as a movable portion 722a, and the rear side may be referred to as a movable portion 722b.
When the compression coil spring 723 of the movable portion 722 receives a load in the direction of shortening the spring length, it resists the load and urges in the direction of lengthening the spring length. For this reason, the compression coil spring 723 biases the front side in the direction of decreasing the inclination in the state shown in FIG. is biased in the direction in which the inclination of the Therefore, when there is an external force to change from FIG. 3(b) to FIG. 5(a) or 5(b), the compression coil spring 723 suppresses such a change.
Due to this technical significance, instead of the compression coil springs 723, the four movable parts 722 may use other elastic members that suppress the above-described change, such as rubber members (not shown), air cylinders, etc. may be used. In this embodiment, an elastic member such as the compression coil spring 723 is used instead of an air cylinder, so that the configuration can be simplified.

The housing 70 is rotatable around a rotating shaft 721 held at a predetermined height H. As shown in FIG. In FIG. 5A, in which the housing 70 tilts forward, the front movable portion 722a contracts to a length La1 (L>La1), and the rear movable portion 722b extends to a length Lb1 (L<Lb1 )become.
In addition, in FIG. 5B where the housing 70 is tilted to the rear side, the movable portion 722a on the front side extends to a length La2 (L<La2), and the movable portion 722b on the rear side contracts to a length Lb2 ( L>Lb2).

Here, as described above, the rotating shaft 721 according to the present embodiment is positioned substantially at the center of the lower housing 720 in the front-rear direction. are the same. Specifically, length La1 and length Lb2 when contracted are equal to each other, and length La2 and length Lb1 when expanded are also equal to each other. In other words, the difference between the amount of movement, that is, the length L and the lengths La1, La2, Lb1, and Lb2 are all equal.
However, the present invention is not limited to this, and the rotating shaft 721 can also be shifted to any position in the front-rear direction of the lower housing 720 . In this case, the amount of movement of the movable portion 722a on the front side and the amount of movement of the movable portion 722b on the rear side are different from each other. For example, when the rotating shaft 721 is closer to the front side in the front-rear direction, the amount of movement of the front movable portion 722a is small, and the amount of movement of the rear movable portion 722b is large.

Further, in this embodiment, the compression coil springs 723 of the four movable parts 722 have the same spring constant. Although the load of the user trying to tilt the is the same, it is not limited to this. That is, the spring constants of the front movable portion 722a and the rear movable portion 722b may be different from each other. In other words, the degree of suppression for suppressing the change of tilting the step 10 forward and the degree of suppression of suppressing the change of tilting the step 10 backward are different from each other.
Since the load when changing to FIG. 5A and the load when changing to FIG. For example, the spring constant of the movable portion 722a on the front side is made larger than that of the movable portion 722b on the rear side to make it difficult to tilt forward, thereby increasing the exercise load.

6A and 6B are left side views of the physical exercise apparatus 1 showing a state in which the user's foot is placed on the step 10. FIG. FIG. 4 is a diagram showing a state in which the step 10 is inclined with respect to the floor FL; All of (a) to (c) are views viewed from the direction of arrow A in FIG.
In the physical exercise apparatus 1 shown in FIG. 6(a), the step 10 is in a flat state, and the toe side TS and heel side HL of the user's foot are substantially at the same height from the floor FL. The state of step 10 in FIG. 4A is an example of the first posture. The flat state of the step 10 shown in FIG. 4(a) can be said to be the state in which the step 10 is least inclined with respect to the floor FL.

In FIGS. 6(b) and (c), the step 10 is more inclined than in FIG. 6(a).
6(b) and (c) are slanted in opposite directions. More specifically, in FIG. 6B, step 10 is a toe-down state in which the user is inclined forward and the user's toe side TS is lower than the heel side HL. This is an example of the posture of FIG. 6(c) shows step 10, which is a toe-up state in which the user is inclined backward and the user's heel side HL is lower than the toe side TS, which is the third posture. An example.

Thus, the step 10 is flat, as well as sloping forward and backward of the user. For this reason, when the user standing on step 10 alternately performs the actions shown in FIGS. Exercise can be given or given.
Further, by maintaining the toe-down state shown in FIG. 6B, the muscles of the instep and shin can be stretched, for example. Further, by maintaining the toe-raised state shown in FIG. 6(c), for example, the region from the calf muscle to the Achilles tendon can be stretched. A more effective exercise can be performed by performing the stretching motion while vibrating the step 10 by operating the electric motor 51 (see FIG. 2) or the fine vibrating section 53 (see FIG. 2).

Although illustration is omitted, the user may exercise while standing on the step 10 toward one side in the width direction instead of standing on the step 10 toward the front side in the front-rear direction. In this case, the inclination of FIG. 6B causes the user's right foot to be lower than the left foot, and the inclination of FIG. 6C causes the user's left foot to be lower than the right foot. It becomes possible to perform movements that expand the range of motion of the

Note that the above-described first posture may be a state in which the step 10 is in a flat state, or a state in which it is inclined to either side in the front-rear direction. The second orientation and the third orientation are set with respect to the first orientation.

<Back cover 80>
Next, the back cover 80 will be described in more detail.
7, 8, and 9 are diagrams for explaining the configuration of the back cover 80. FIG. 7 is a plan view of the body exercise device 1, FIG. 8 is a front view of the body exercise device 1, and FIG. 9 is a body exercise device. 1 is a bottom view of FIG.
The physical exercise device 1 has an overhang 82 attached to the back cover 80 and having a plurality of legs 81 . The protruding portions 82 are provided on the left and right sides, respectively, and protrude outward from the step 10 . In FIG. 7, which is a plan view, the projecting portion 82 is partially indicated by dashed lines, and the positions of the four movable portions 722 are indicated by dashed lines. The protruding portion 82 is an example of a protruding portion.

As shown in FIG. 8 or FIG. 9, each projecting portion 82 of the back cover 80 has a leg portion 81 having a movable portion 722 located near the center in the width direction, and a leg portion having no movable portion 722 near the end portion. 81 is located.
Further, as shown in FIG. 9, the back cover 80 has four legs 81 with movable portions 722 and six legs 81 without movable portions 722 .

In each projecting portion 82, the leg portion 81 that does not have the movable portion 722 is positioned at the center in the front-rear direction, and positioned at the peripheral edge portion of the step 10 on the front and rear sides thereof. More specifically, the leg portion 81 located on the periphery of the step 10 has a portion located outside the back cover 80 . In other words, the distance between the legs 81 in the front-rear direction is larger than the dimension of the back cover 80 in the front-rear direction. As a result, the body exercise apparatus 1 that is used while being inclined in the front-rear direction can be stably placed on the floor FL, and instability during use can be prevented.
The leg portion 81 positioned at the peripheral portion of the step 10 is attached to the projecting portion 82 via a reinforcing plate 83 extending toward the center of the leg portion 81 in the front-rear direction. Thereby, the rigidity of the mounting portion of the leg portion 81 can be increased.

As shown in FIG. 7 or FIG. 9 , each projecting portion 82 is located near the four corners of the step 10 and has a portion projecting outward from the periphery of the step 10 . A mounting portion 84 for detachably mounting a rope 85 (see FIG. 8) used by the user is formed at the tip of this portion.
The projecting portion 82 is formed such that the four mounting portions 84 are spaced apart from each other in a plan view. Also, the rope 85 can be attached at a position away from the step 10 in plan view. Therefore, when the user uses the rope 85 for exercise or gets on or off the step 10, the rope 85 can be prevented from clinging or entangling the user. In addition, when the user stands on the step 10 and exercises while holding the rope in his/her hand, even if tension is applied to the rope 85, it can be received by the protruding portion 82 and the leg portion 81, and the physical exercise device 1 due to the tension. deformation can be suppressed.

Here, the rope 85 is an example of a rope member, and is held by the hand of the user who is exercising while standing on the step 10 to apply a load to the upper body such as the arm and to keep the user's balance. . It is common to hold one rope 85 in each hand, or two ropes 85 in one hand. can.

As shown in FIG. 8 or 9, the back cover 80 has a locking mechanism 90 for locking the step 10 so that it does not rotate. The lock mechanism portion 90 has an operation portion 91 that can be operated on the front side in the front-rear direction. In the present embodiment, the lock is set by pushing the operation portion 91, and the lock is released by pulling it out. The locking mechanism part 90 is an example of fixing means.

10A and 10B are diagrams for explaining the lock mechanism portion 90, in which FIG. 10A shows an unlocked state, and FIG. 10B shows a locked state. 10(a) and 10(b) are perspective views showing a state of looking up slightly from below at arrow A in FIG. 1, and illustration of some parts is omitted.
The lock mechanism portion 90 includes the operation portion 91 that is elongated in the front-rear direction and is attached to the back cover 80 , and the stay 92 that is elongated in the front-rear direction and is attached to the lower housing 720 . Further, the lock mechanism portion 90 includes two lock movable portions 93 attached to the lower surface of the stay 92 and a slide plate 94 positioned at the lower end of the lock movable portion 93 .
The two locking movable parts 93 are positioned on the front side and the rear side in the front-rear direction with respect to the rotating shaft 721 . The locking movable portion 93 includes a downwardly extending shaft portion and a compression coil spring attached to the shaft portion.

The operating portion 91 is slidable in the front-rear direction with respect to the back cover 80 (see FIG. 9, for example), and has two through holes 95 capable of receiving the shaft portion of the locking movable portion 93 .
When the operating portion 91 is in the unlocked position shown in FIG. 10A, the shaft portion of the movable locking portion 93 and the through hole 95 are at the same position in the front-rear direction. can enter. Therefore, in the case of FIG. 10A, rotation of the lower housing 720 about the rotation shaft 721 is allowed.
On the other hand, when the operating portion 91 is in the lock setting position shown in FIG. 10B, the position of the shaft portion of the locking movable portion 93 is different from that of the through hole 95 in the front-rear direction. Therefore, the shaft portion cannot enter the through hole 95 and is restrained by the operating portion 91 . Therefore, in the case of FIG. 10B, rotation of the lower housing 720 about the rotation shaft 721 is prevented.

In this embodiment, when the step 10 is in a flat state, the step 10 is locked by the lock mechanism 90 so that it does not tilt. Alternatively, the lock mechanism section 90 may be configured so that the step 10 cannot rotate around the rotation shaft 721 .
As such a configuration, for example, when locking is set in a state in which the front side of the step 10 is higher than the rear side of the step 10 (see FIG. 6C), the locking movable portion 93 is attached only to the front side of the rotating shaft 721, and the toe An example in which the shaft portion of the locking movable portion 93 is restrained by the operating portion 91 in the raised state can be adopted.

The step 10 whose tilt in the front-rear direction is locked by the lock mechanism 90 can be vibrated by the vibration generator 50 . That is, the step 10 can be vertically vibrated by the operation of the electric motor 51 (see FIG. 2), and the step 10 can be finely vibrated by the operation of the fine vibrator 53 .

As described above, the present embodiment has been described including the modified examples, and the summary is as follows.
In the physical exercise apparatus 1 according to the present embodiment, the step 10 on which the user stands can be tilted by the user's motion, so that the flat state can be changed to the state where the toes are lowered or the state where the toes are raised (see FIG. 6). When the step 10 is put in the toe-down state or the toe-up state, the spring force acts in the direction of returning to the flat state, and the change to the toe-down state or the toe-up state is suppressed.

The degree of suppression by the spring force may be the same in the case of changing to the toe-down state and the case of changing to the toe-up state, or may be configured to provide a difference between the two. This makes it possible to exercise in a variety of ways. Alternatively, either the former or the latter may be selected and switched by a user's operation. Thereby, a user's option can be expanded.

An elastic member such as rubber may be used instead of the spring, or an air cylinder or the like may be used. By using the elastic member, the configuration can be simplified as compared with the case of using an air cylinder or the like.
It should be noted that, for example, by using an air cylinder or the like, a configuration may be adopted in which the user can select the same degree of suppression between the front and rear or different degrees of suppression between the front and rear.

In addition, in addition to the case where the amount of movement from the flat state to the moving end of the toe-down state and the moving amount from the flat state to the moving end of the toe-up state are the same, it is configured to provide a difference between the two. You can This makes it possible to exercise in a variety of ways.

The step 10 can be locked in a flat state by a lock mechanism 90 (see FIG. 10), but can be locked in a tilted state, that is, in a state where the toe is lowered or a state where the toe is raised, or at an intermediate position. may be configured. This makes it possible to exercise in a variety of ways.
Even in the lock setting state, the step 10 can be vertically vibrated or finely vibrated, and both the vertical vibration and the fine vibration can be performed.

The body exercise device 1 includes a protruding portion 82 protruding outward from the step 10 (see FIG. 7). Ten leg portions 81 are attached to the back cover 80 via the projecting portion 82 . Compression coil springs 723 for generating the spring force are positioned on the inner surface side of the back cover 80 in four of the ten legs 81 (see FIG. 4).

In addition, since the four legs 81 located near the four corners of the step 10 have portions located outside the step 10 (see FIG. 9), the step 10 is repeatedly performed in a toe-down state and a toe-up state. Even if it is used as above, the physical exercise apparatus 1 can be stably placed on the floor FL.

Furthermore, attachment portions 84 for detachably attaching ropes 85 (see FIG. 8) are provided at the four ends (see FIG. 7 or FIG. 9) of the projecting portion 82 so that the user can exercise using the ropes. It makes it easier to do
