DISCLOSURE OF THE INVENTION The present invention has been made in view of the above points, and can be used in various ways for promoting health and rehabilitation, and when not used for the above purpose. It is another object of the present invention to provide a multipurpose chair which can be used as a normal chair.

[0004]

Means for Solving the Problems To solve the above-mentioned problems, the invention according to claim 1 has a seat portion and a support portion, and the seat portion is provided by the support portion provided below through a cushion material. By providing a multipurpose chair characterized by being supported so as to be able to vibrate and tilt freely, the user can freely vibrate and tilt the seat part by shifting his / her own weight.

The invention according to claim 2 is characterized in that the seat portion is tiltably supported by the support portion via a plurality of cushion members and a ball joint provided substantially at the center of the cushion members. With the multipurpose chair according to the first aspect, it is possible to prevent unstable movement such as lateral flow of the seat.

According to a third aspect of the present invention, there is provided the multipurpose chair according to the first or second aspect, further comprising a lock mechanism for fixing vibration and inclination of the seat.
The seat can be fixed and used as a normal chair.

According to a fourth aspect of the present invention, there is provided the multipurpose chair according to any one of the first to third aspects, wherein a contact portion for generating a sound by contact is provided on the seat portion. When a predetermined inclination is obtained in the seat due to the weight shift of the user, a sound can be generated.

According to a fifth aspect of the present invention, there is provided a multi-purpose chair according to the fourth aspect, wherein a plurality of contact portions are provided, and the contact portions have different scales. Music can be freely played by weight shift.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the accompanying drawings. FIG. 1 is a schematic diagram showing an example in the embodiment of the present invention. As shown in the figure,
The seat 1 with the backrest 2 attached is a ball joint 4
, And is supported above by a support portion 3 via four coil springs 5 provided at the periphery of the ball joint 4 and separated from each other. However, the coil spring 5 does not need to be particularly limited to four.

A rotary shaft 6 extends below the support portion 3, and the rotary shaft 6 is connected to a support cylinder 7 at a lower portion thereof by fitting. By rotating the rotation shaft 6 around the central axis with respect to the support cylinder 7 at the connection portion, the seat 1 can be rotated, and the fitting amount of the rotation shaft 6 with the support cylinder 7 is changed. The height of the seat 1 can be adjusted. In addition, support cylinder 7
From the lower part, for example, five legs 8 are extended in a substantially horizontal direction, thereby securely supporting the chair body. A user (not shown) seated on the chair having the above configuration changes the manner of weight application by twisting his / her waist while maintaining balance, and freely moves the seat 1 in accordance with the movable range of the ball joint 4. Can be inclined.

FIG. 2 is a schematic view showing the periphery of a cushion portion of a multipurpose chair without a ball joint 4, which is another example of the embodiment of the present invention. Since the seat portion 1 is supported by the support portion 3 via only the coil spring 5 without passing through the ball joint 4, the vibration in the horizontal direction and the vertical direction is not fixed. Therefore, various fluctuations such as not only inclination but also lateral flow occur in the seat portion 1. In other words, in the case of one example, the inclination of the seat portion 1 becomes free, whereas in the case of another example, the inclination and the vertical and horizontal vibrations of the seat portion 1 become free.

FIG. 3 is a schematic view of a multi-purpose chair in which music can be freely performed by tilting the seat 1 in one example. A plurality of contact portions 10 capable of generating a sound by contact are provided on the bottom surface of the seat 1, and a contact plate 11 protrudes above the support portion 3 below the contact portion 10. If a predetermined inclination is given to the seat 1 by shifting the weight of the user, the contact portion 10 corresponding to the inclination comes into contact with the contact plate 11 thereunder, and a desired sound can be generated. Therefore, if different scales are given to the contact portions 10, the music can be freely played by repeating weight shift. In this example, the contact portion 10 is provided on the bottom surface of the seat portion 1 and is in contact with the contact plate 11, but the contact portion 10 may be provided at another portion of the seat portion 1 and contact with another member.

FIG. 4 is a schematic view showing a case where the chair shown as an example is used as a normal chair by fixing the inclination of the seat portion 1. In order to fix the seat 1, a lock mechanism is required. In this example, the lock mechanism is provided by, for example, detachably attaching the cylindrical case 12 so as to cover the entire coil spring 5. As a result, the inclination of the seat 1 is prevented, so that the seat 1 can be used as a normal chair. Further, if the casters 9 are respectively attached to the tips of the legs 8 according to circumstances, the chair body can be easily moved back and forth and right and left. In other examples as well, if a lock mechanism is provided and the vibration and inclination of the seat portion 1 are fixed, the seat can be used as a normal chair.

[0014]

As described above, according to the first aspect of the present invention, the user can freely change the inclination of the seat portion by shifting his / her own weight. Therefore, by repeating the change of the inclination, the user twists his / her waist many times and gives an appropriate stimulus to the abdominal muscles and the like, so that a health promotion effect such as prevention of diet and low back pain can be achieved. In addition, the seat is in an unstable state, and the posture can be corrected by sitting thereon and performing the above-described exercise while maintaining its own posture. In addition, since the exercise center and the reflex nervous system of the user are activated in the exercise, the exercise is effective for rehabilitation. Further, it can be used as a playground equipment for children.

According to the second aspect of the present invention, the seat can be tiltably moved while suppressing irregular movement such as lateral flow, so that effects such as health promotion and rehabilitation can be achieved. User safety can be improved.

According to the third aspect of the present invention, since the seat can be used as a normal chair by fixing the seat by the lock mechanism, various uses can be realized by one device. Also, unlike a conventional dedicated device, there is no need to secure a dedicated storage space other than at the time of use, so that space can be effectively used.

According to the fourth aspect of the present invention, by providing the contact portion for generating a sound, the user can tilt the seat portion by moving his / her own weight while sitting down, and can sound freely. By using this, it is possible to confirm that a desired inclination has been obtained, and it is possible to add entertainment to exercise that tends to be monotonous.

According to the fifth aspect of the present invention, since a plurality of contact portions are provided and different scales are given to each of the contact portions, the music can be played by continuously combining the inclinations of the seat portions. . Thereby, while enjoying the amusement element, it is possible to obtain effects such as prevention of lower back pain by strengthening muscle strength around the waist, diet and posture correction, and the like. In addition, in the present invention, a high rehabilitation effect can be expected by giving the user a high level of stimulation. This is because a series of actions that continuously realize the necessary inclination of the seat after thinking of a song are advanced exercises that link the user's brain and body. Therefore, for example, when used in facilities for the aged, an effect of preventing blur can be expected, and when used as a playground equipment for children, an effect of promoting brain development can be expected.
