Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relaxation chair, and more particularly, to a relaxation chair provided with a vibration member that receives low-frequency current in a low-frequency range and generates mechanical vibration.

[0002]

2. Description of the Related Art Heretofore, there has been proposed an idea of attaching a relaxation vibration device to a chair. For example, Japanese Patent Publication No. Hei 6-18599 (Body Sonic Co., Ltd.) states that a vibration unit that generates mechanical vibration by receiving a bass current of music at a position corresponding to a part of the chair where the user feels comfortable. The idea is to connect the vibrating unit to a circuit that causes the low-frequency current to repeatedly attenuate and increase over time, and alternately output low-frequency currents of different frequencies in synchronization with the repetitive operation. "
Is disclosed.

Therefore, a vibration unit attached to a relaxation chair uses music or the like as a sound source, a voltage-controlled oscillator that repeatedly outputs a low-frequency current of the sound source, a voltage-controlled amplifier that amplifies a voltage, and a feeling of comfort. A human body support (such as a chair) is vibrated via a frequency control oscillator or the like for generating a frequency to be generated.

[0004] By the way, vibrations that make the human body feel comfortable, for example, vibration sounds such as toe-toe-toe-toe-toe, or waves such as waves rushing to a sandy beach, etc. With regard to the above, there was an issue to be studied and devised in various ways about "where" and "how to attach" the vibration member for relaxation to the chair.

[0005] In the inventions such as a chair-type electric massager (Japanese Utility Model Application Laid-Open No. 54-140592), the main purpose is to obtain a massage effect for each part of the human body. It may be appropriately incorporated in the urethane foam in the skin together with the material or the vibration unit.

[0006] However, when a relaxation vibration member for generating vibrations that make the human body feel comfortable is attached to a chair, the "realistic" type is used regardless of whether it is a type with a built-in skin or a type with a built-in skin. The problem that "vibration" cannot be realized has arisen. In other words, as a result of the experiment, in the case of the chair with the inner skin or the outer skin, the way of transmitting vibration as relaxation is insufficient, and therefore, as a "mentally comfortable bodily sensation", A person who expects a realistic bodily vibration could not be given a sufficient satisfaction. In addition, research has shown that applying the vibration of the relaxation vibrating member to the elbow of a human body rather diminishes the "mentally pleasant bodily sensation". In other words, it was found that a local effect to the part (such as the waist) where the comfort of the vibration is felt enhances the relaxation effect.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a first object of the present invention is to provide a mentally comfortable bodily sensation even to a person who expects a more realistic bodily vibration. Is to provide a relaxation chair that can provide A second object is to provide a relaxation chair that does not cause discomfort to the sensible person via the elbow.

Each vibrating member (vibrator) 6 has a disk shape as shown in FIG. 2, and is fixed to the back side of the cushion support spring 30 and the back side of the vibration propagation support 31, respectively. Each vibrating member (vibrator) 6 is a newly developed product. Desirably, the chair 1 has a vibro transducer (conversion of an acoustic signal into mechanical vibration) for transmitting a sense of realism as a realistic vibration sound. Converter).

In the above configuration, a part of the sound output from the sound source generating means 2 flows from the pair of left and right speakers 7, 7 of the chair 1 through the sound control device 3, partly passing through an amplifier or the like. In addition, a part of the sound source signal is a sound source signal whose high frequency is cut by a low-pass filter (not shown), and the sound source signal is amplified by an amplifier to become a sound signal for vibration. become.

Therefore, the sensible person sitting on the chair 1 listens to the acoustic signals emitted from the left and right speakers 7, and on the other hand, while appropriately reclining in the chair 1, relaxes the vibration members 6, 6. It is possible to experience a vibrating sound, such as a toe-toe-toe-toe, or a sound such as a wave that rushes toward a sandy beach or the like. In this case, if the sound source generation means 2 is, for example, a television broadcast, the image of the broadcast content appears on the screen of the video / sound generation means (not shown), and the sound (from the left and right speakers 7, 7 of the chair 1). For example, music). Therefore, in such an implementation environment, the sensation system X is a sensation system of video, sound, and vibration.

Here, "directly transmitted" means that the vibration members 6, 6 are directly attached to the frames 11, 12 as the aggregate of the chair 1 through the vibration propagation supports 30, 31, respectively.
This means that the relaxation vibration sound of No. 6 is transmitted to the perceived person more realistically.

At this time, the vibration sounds for relaxation of the vibration members 6 and 6 are generated because the vibration propagating supports 30 and 31 have a wavy spring force (less flexible) or a plate material having an excellent propagation rate. The conductivity for the seat frame 12 is not diminished.

On the other hand, the frame-shaped base frame 11 is basically a separate product from the seat frame 12, and
The chair 1 has a vibration absorbing member (anti-vibration material) 15.
The vibration of the arm tress portion 16 can be suppressed in an absorbing manner.
