Description

VIBRATING CHAIR

The present disclosure relates to a vibrating chair which may strongly transmit vibration to a spectator using a vibrating unit directly fastened to an insert inserted into and formed integrally with a cushion member disposed in a backrest portion or a seat portion, and may reduce time and costs for assembly, thereby reducing production costs.

Movie theaters may be widely classified into a general movie theater which shows a general movie (two-dimensional image), a special movie theater at a place for providing amusement, such as a theme park, and an exhibition movie theater for education or for providing public relations at a museum/public relation center/exhibition hall.

In general, a person mainly sees three-dimensional images, but because a person sees two-dimensional images when viewing the images, which are captured using image capturing devices such as a camera or a camcorder, through a screen in a general movie theater, and as a result, a stereoscopic effect is greatly degraded.

A movie screening facility in the related art such as a general movie theater simply provides movies to spectators, but recently, due to propagation of digital media capable of performing bidirectional signal communication and development of movie industries, new types of movies are provided, and various effects are provided to the spectator in addition to movie screening. That is, the general movie theater in the related art is a place which simply allows people to see the movies in visual and auditory manners, but recently, the movie theater becomes a place that allows people to see the movie in a visual manner, and allows people to directly feel various effects.

In general, the movie theater where people may feel stereoscopic effects of the movies in a visual manner while seeing the movies, which are specially made, is generally called a '3D movie theater', and other than the 3D movie theater, a movie theater, which allows people to feel five sensory senses such as tactile sense, olfactory sense, and the like, in addition to visual and auditory senses when seeing the movies, is referred to as a '4D movie theater'.

Recently, in the 3D movie theater, the 4D movie theater, or the theme movie theater, in order to provide spectators with vibration corresponding to situations in the movie, vibrating units are installed in chairs in the movie theater, and the chairs are controlled to be automatically vibrated by allowing the vibrating unit to be operated in conjunction with heavy low tone sound of the movie, thereby allowing the spectators to more strongly feel the vibration.

Hereinafter, a vibrating chair in the related art will be described in more detail.

FIG. 1 illustrates a front view of a vibrating chair 10 in the related art, and FIG. 2 illustrates a side view of the vibrating chair 10 in the related art.

Referring to FIGS. 1 and 2, the vibrating chair 10 in the related art has fixing units 60 fixed to a floor 70.

A pair of fixing units 60 is generally provided.

A backrest portion 20 is fixedly installed at portions of the pair of fixing units 60, a seat portion 30 is rotatably installed at portions of the pair of fixing units 60 by connecting units 50, and a pair of armrest portions 40 is disposed at upper ends of the pair of fixing units 60.

The backrest portion 20 has a first cushion member 22 therein in order to provide comfort to the spectator, and the entirety of a front side and a lateral side of the first cushion member 22 and a part of a rear side of the first cushion member 22 are covered by a first cover 21. In addition, a rear side of the first cushion member 22 is covered by a first fixing bracket 23. A transducer 34 is installed in the first cushion member 32.

The seat portion 30 has a second cushion member 32 therein in order to provide comfort to the spectator, and the entirety of a front side and a lateral side of the second cushion member 32 and a part of a rear side of the second cushion member 32 are covered by a second cover 31. In addition, a rear side of the second cushion member 32 is covered by a second fixing bracket 33. A transducer 34 is installed in the second cushion member 32.

Korean Utility Model Registration No. 20-0419026 also discloses the technical spirit like the aforementioned description.
