BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swing seat used for leisure facilities, training (simulated experiences), health equipment, etc.

0002

2. Description of the Related Art Conventionally, a shaking mechanism using hydraulic pressure has generally been used to shake a seat. FIG. 3 shows an example of a hydraulic shaking mechanism, and in the figure, 10 is a shaking seat, and 13 is a hydraulic cylinder. This shaking mechanism is operated according to the system configuration diagram shown in FIG. 4, for example.

0003

SUMMARY OF THE INVENTION The above-mentioned prior art has the following problems. (1) In order to give vibration or sway to the seat 10,
As shown in FIG. 4, a hydraulic pressure generating device 11, a servo valve 12, a hydraulic cylinder 13, a control section 14, a hydraulic piping 15, etc. are required, and there are many components and the cost is high. (2) It is necessary to secure a location for installing the above components. The hydraulic pressure generating device (power unit) 11 is composed of an electric motor and a hydraulic pump, and generates quite loud noise when driven, so noise countermeasures are required, such as providing a chamber dedicated to the hydraulic pressure generating source. (3) Experts are required to operate and maintain the hydraulic devices 11 to 15, which requires securing manpower and costs. (4) The number of component parts of the hydraulic devices 11 to 15 is large, making maintenance and management time-consuming. (5) Swing When the seat is vibrated, the load (F) generated by the acceleration of the vibration is F=m·G, where the mass of the shaking part is (m) and the acceleration is (G).

[0004] Since the swing seat 10 is supported by the hydraulic cylinder 13, the hydraulic cylinder 13 also receives the vibration load, and the load is further transmitted to the base 16, which is the lower mounting portion of the hydraulic cylinder. Since the working fluid in the hydraulic cylinder is incompressible oil, this load is transmitted to the foundation 16 with almost no buffering. Therefore, a static load and a dynamic load due to vibration acceleration will be transmitted to the hydraulic cylinder 13 and the hydraulic cylinder lower mounting base 16, so it is necessary to take both loads into consideration in the design of these (hydraulic cylinder body and foundation).

[0005] In other words, the faster the seat movement is made, the more the vibration load increases, and the design load of the cylinder increases, making it necessary to increase the diameter of the cylinder and strengthening the soil bearing capacity of the foundation, which leads to an increase in costs. becomes. (6) It is extremely difficult to take the above measures in facilities where it is necessary to particularly avoid the transmission of vibrations and noise to adjacent areas, such as when installing the above equipment in a part of an office building or retail building. Or, even if it is technically possible, the cost will increase significantly.

SUMMARY OF THE INVENTION An object of the present invention is to provide a swinging seat that is simple, compact, and inexpensive in structure and that transmits small dynamic loads to the foundation.

[0007]

[Means for Solving the Problems] (1) A vibration generator that generates vibration by itself is attached directly below the seat. (2) Support the seat with multiple elastic bodies.

[0008]

[Operation] By the above-mentioned means (1), the weight to be vibrated is reduced and the dynamic load is reduced. The aforementioned measure (2) reduces the dynamic loads transmitted to the foundation.

[0009]

Embodiment An embodiment of the present invention will be explained with reference to FIGS. 1 and 2. 1 is a seat on which a person sits, 1a is a pedestal for supporting the seat 1, and a vibration generator 2 for applying vibration to the seat is installed directly under the pedestal 1a. The frame 1a is supported by three elastic supports 3.
It is supported to the ground 5 via the joint 4. The vibration generator 2 itself is well known, and can be an electric motor with eccentric weights attached to both ends of the output shaft, or an electromagnetic vibrator used in electric massagers, etc. As the elastic support 3, a spring, an oil damper, an air cushion, etc. can be used.

Since the swinging seat of the present invention is constructed as described above, the weight of the vibrated parts (seat 1, pedestal 1a) is reduced, and the distance between the vibrated body and the vibration source is shortened, so that vibrations can be reduced. High transmission efficiency. Therefore, high acceleration can be applied to the seat and the person with a small amount of power (in the case of a single-person seat, 0.
1G to 2G possible with 25KW). Furthermore, a single vibration generator can be used as a substitute for all the components of a conventional hydraulic vibration mechanism, such as a hydraulic source generator, piping, servo valve, hydraulic cylinder, etc.

By supporting the seat 1 with a plurality of elastic supports 3, the vibration load generated when the seat 1 oscillates can be absorbed by the deflection of the elastic supports. Therefore,
The load transmitted to the foundation can be significantly reduced (1/5 to 1/10).

[Effects of the Invention] The swing seat according to the present invention includes a frame supported substantially horizontally and movably by a plurality of elastic supporting members;
By comprising a seat attached to the upper side of the pedestal and a vibration generator attached to the lower side of the pedestal, the following effects are achieved. (1) The structure is simple, maintenance is easy, and the price is low. (2) Seating (mounting) for a vibration generator that generates vibrations by itself
By attaching it directly below the seat, vibration transmission efficiency is high and high acceleration can be applied to the seat with a small amount of power. (3) The vibration acceleration of the seat can be easily changed by simply changing the capacity of the vibration exciter. (4) It is possible to greatly reduce the vibration load caused by the vibration of the seat, and the strength design conditions for the foundation can be relaxed.
