Utility Model Registration No. 3149092

In the above-mentioned prior art, the first mode in which the vibrating member is vibrated up and down by driving the first motor with the second motor stopped is selected, and conversely, the second motor is operated with the first motor stopped. The second mode in which the vibrating member is vibrated left and right by driving is selected, and the third mode in which the vibrating member is combined with both vertical vibration and left and right vibration by driving the first motor and the second motor at the same time is selected. It has been selected and explained to provide a variety of cosmetic effects.

However, in the case of the prior art, since the two 8-shaped link rods supporting the central axis are swung left and right to vibrate the vibrating member left and right, the left and right vibration by the second mode is extremely monotonous. Therefore, there is a problem that the effect as vibration given to the user's body is poor.

This type of body exercise vibrator can be used in various ways, but mainly, the user stands on the vibrating member or puts one foot on the vibrating member in such a state. By receiving the vibration of the vibrating member from the sole of the foot, the purpose is to improve the sense of balance and promote blood circulation by the small vibration. However, when performing only monotonous left-right vibration, the user can stabilize the upper body by following the legs to the left and right, so it is not very effective in improving the sense of balance, and it is also sufficiently effective in promoting blood circulation. I can't expect it.

In view of such a problem, when the vibrating member is vibrated left and right, the present invention always generates a slight vibration in the vertical direction at the same time as the left and right vibration, which can greatly contribute to the improvement of the sense of balance and the promotion of blood circulation. The purpose is to provide a vibrator for physical exercise.

Therefore, where the present invention is configured as a means, the vibrating member is provided by axially supporting the supporting means erected on both sides of the seat member in the width direction with the axial means provided on both sides of the center of the vibrating member in the width direction. Is freely vibrated up and down around the shaft means and can be vibrated left and right together with the shaft means, and a vertical drive mechanism that vibrates the vibrating member up and down by a drive source installed on the seat member and the vibrating member left and right. In a body exercise vibrator provided with a left-right drive mechanism for vibrating, the support means is provided with a guide hole extending in the left-right vibration direction, and the shaft means of the vibrating member is inserted into the guide hole so as to be movable left and right. When the left and right drive mechanism vibrates the vibrating member left and right, a micro-vibration generating means consisting of irregularities arranged alternately in the left-right movement direction is provided on the bottom surface of the guide hole that supports the means from below. The point is that the shaft means is configured to give micro-vibration to the vibrating member by moving left and right while overcoming the unevenness of the micro-vibration generating means.

In a preferred embodiment of the present invention, the shaft means includes a shaft member and an outer cylinder member rotatably mounted on the shaft member, and the outer cylinder member is inserted into the guide hole so as to be movable left and right. ing.

At this time, it is preferable that the outer cylinder member is configured to rotatably attach to the shaft member via a bearing.

According to the present invention, when the vibrating member 2 vibrates left and right by the left-right drive mechanism 6, the shaft means 13 is moved by the micro-vibration generating means 18 while vibrating rattlingly, and the shaft means 13 with respect to the vibrating member 2. Since it gives a slight vibration in the vertical direction, it can bring about a great effect for improving the user's sense of balance, promoting blood circulation, and the like.

It is configured to enable OFF and ON / OFF for simultaneously driving / stopping both the first drive source 7a and the second drive source 7b.

However, in addition to the configuration in which two electric motors are provided as shown in the figure, although not shown, only one drive source 7 composed of one electric motor is provided, and the drive source and the upper and lower sides are provided. A power transmission path is formed between the drive mechanism 5 and the left and right drive mechanism 6, and a clutch means such as an electromagnetic clutch that enables connection / disconnection of the power transmission path is provided so that each clutch means is electrically controlled. This may be configured to enable individually selective drive and stop of the vertical drive mechanism 5 and the left and right drive mechanism 6, and simultaneous drive and stop of both.

(Structure in vibrating member)
The vibrating member 2 is pivotally connected to the driven piece 12a which is pivotally connected to the pivot piece 11a of the eccentric cam 10a of the vertical drive mechanism 5 and the pivot piece 11b of the eccentric cam 10b of the left and right drive mechanism 6. A driven piece 12b is provided.

A shaft means 13 for connecting the brackets 3 and 3 of the vibrating member 2 to the support means 4 and 4 of the seat member 1 is provided. In the case of the illustrated embodiment, the shaft means 13 is composed of a shaft member 14 extending in the width direction of the vibrating member 2 and an outer cylinder member 16 rotatably exteriorized at both ends of the shaft member 14 via bearings 15. A flange 16a is provided at the shaft end of the outer cylinder member 16.

(Support configuration of shaft means by support means)
The bracket 3 is formed with an insertion hole 3a through which the outer cylinder member 16 is rotatably inserted, and the support means 4 is formed with a guide hole 17 through which the outer cylinder member 16 is rotatably inserted. Has been done.

As shown in FIGS. 4 and 5, when the vibrating member 2 faces the seat member 1 from above, the brackets 3 and 3 face the outer surfaces of the support members 4 and 4, and the insertion holes 3a and the guide holes 17 face each other. Communicate with. Therefore, when the outer cylinder member 16 is attached to both ends of the shaft member 14 from the outside of the insertion hole 3a via the bearing 15 with the shaft member 14 arranged in the center, the bracket 3 and the support member 4 are connected by this. Then, the vibrating member 2 is installed in a connected state above the seat member 1. At this time, although not shown, a retaining means for preventing the outer cylinder member 16 from falling off from the end portion of the shaft member 14 is provided, and the outer cylinder member 16 is inserted into the insertion hole in the retaining state. When inserted through 3a and the guide hole 17, the flange 16a is attached to the outer surface of the bracket 3.

Incidentally, in the case of the illustrated embodiment, the shaft means 13 is composed of one long shaft member 14, but may be composed of two short shaft members 14, and each shaft may be composed of two shaft members 14. The outer cylinder member 16 which is externally attached to the member 14 via the bearing 15 may be configured to be inserted into the respective insertion holes 3a and the guide holes 17.

The vibrating member 2 and the seat member 1 arranged in a vertically connected state as described above accommodate the lower portion of the vibrating member 2 in the casing, and also place a floor plate or the like on which the user rides on the vibrating member 2. By wearing it, it is provided as a vibrating machine for physical exercise as a product.

(Means for generating micro-vibration)
As will be described later, when the vibrating member 2 is vibrated left and right by the left and right drive mechanism 6, the shaft means 13 is also moved left and right following the vibrating member 2. Therefore, as shown in FIG. 5, the guide hole 17 is formed. The outer cylinder member 16 is formed to have a length L necessary and sufficient to allow the inserted outer cylinder member 16 to move left and right, and the bottom surface of the guide hole 17 that supports the outer cylinder member 16 from below has a left-right movement direction. Micro-vibration generating means 18 composed of irregularities arranged alternately toward the surface is provided.

At this time, the concave portion 18a and the convex portion 18b constituting the micro-vibration generating means 18 have the peripheral surface of the outer cylinder member 16 recessed into the concave portion 18a when the outer cylinder member 16 moves left and right with respect to the peripheral surface defined by the diameter of the outer cylinder member 16. It is formed so as to have an interval dimension and a height difference so that it can be moved while vibrating rattlingly by overcoming the convex portion 18b.

(Action)
FIG. 6A shows the action related to the vertical vibration of the vibrating member 2. When the first drive source 7a is driven and rotated, the drive shaft 9a of the vertical drive mechanism 5 is rotated, and the driven piece 12a is moved up and down in small steps via the eccentric cam 10a, whereby the vibrating member 2 moves the shaft means 13 up and down. It vibrates up and down the center seesaw structure.

FIG. 6B shows the action related to the left-right vibration of the vibrating member 2. When the second drive source 7b is driven and rotated, the drive shaft 9b of the left and right drive mechanism 6 is rotated, and the driven piece 12b is moved left and right in small steps via the eccentric cam 10b, whereby the vibrating member 2 is moved together with the shaft means 13. Vibrate left and right. At this time, as described above, the outer cylinder member 16 of the shaft means 13 moves while vibrating rattlingly by repeatedly inserting the micro-vibration generating means 18 into the concave portion 18a and overcoming the convex portion 18b. In the case of the illustrated embodiment, the outer cylinder member 16 moves with the vibration waveform 19 as shown in FIG. 7 as a movement locus with microvibration in the vertical direction, and gives such microvibration to the vibrating member 2.

At this time, since the outer cylinder member 16 is rotatably exteriorized at the end of the shaft member 14 via the bearing 15, it is possible to smoothly move left and right while overcoming the micro-vibration generating means 18 by rotation. As a result, wear of the outer cylinder member 16 is prevented, and micro-vibration is suitably generated.

Therefore, when the user stands on the vibrating member and stands up, or receives the vibration of the vibrating member from the sole of the foot with one foot placed on the vibrating member, the left and right sides of the vibrating member 2 are on the sole of the foot. Since a slight vibration in the vertical direction is given at the same time as the vibration, it has a great effect on improving the sense of balance and promoting blood circulation.

When the first drive source 7a and the second drive source 7b are driven and rotated at the same time, the vertical vibration of the vibrating member 2 by the vertical drive mechanism 5 and the left-right vibration of the vibrating member 2 by the left-right drive mechanism 6 are combined. It can be generated, and in this case as well, the micro-vibration by the micro-vibration generating means 18 is simultaneously generated along with the left-right vibration. Since such a micro-vibration by the micro-vibration generating means 18 is given to the vibrating member 2 as a micro-movement in the vertical direction of the shaft means 13, it is generated as a vibration different from the vertical vibration of the seesaw structure by the vertical drive mechanism 5 and vibrates. Greatly contributes to the diversity of.
