SPECIAL EFFECT SENSORY CHAIR ASSEMBLY

The present disclosure relates to a special effect sensory chair assembly which is used in a 4D theater, and has a lower plate which is formed to have a triple structure, an upper plate which is formed to have a double structure, a water injection nozzle which is installed at a rear side of a seat portion, a cover unit which is conveniently installed on the lower plate and the upper plate in a snap-fit manner, and an auxiliary air supply source.

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, even though a person mainly sees three-dimensional images, a person usually 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 visually and auditory, but recently, the movie theater becomes a place that allows people to see the movie not only visually, but also allows people to directly feel other various sensory effects.

In general, the movie theater where people may feel stereoscopic effects of the movies visually 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'.

In general, a special effect sensory chair assembly has been used in the 4D movie theater so as to allow the spectator to feel a vivid special effect that corresponds to film screening information.

FIG. 1 illustrates a front perspective view of a special effect sensory chair assembly in the related art, and FIG. 2 illustrates a front view illustrating a state in which a cover unit is removed from the special effect sensory chair assembly in the related art.

The chairs 20 may be installed over the drive unit 30. The chair 20 has a backrest portion 21, and a seat portion 22. According to the exemplary embodiment of the present disclosure, the chair 20 may have an armrest portion, and a holder for accommodating a beverage may be formed at a part of the armrest portion, but the present disclosure is not necessarily limited thereto.

The chairs 20, which are installed over the drive unit 30, transmit motion, which corresponds to film screening information, to spectators in accordance with operations of the actuators 33 installed in the drive unit 30. According to the exemplary embodiment of the present disclosure, two or four chairs 20 may be integrally installed over the drive unit 30 in order to reduce costs required for installation and maintenance, but the present disclosure is not necessarily limited thereto.

Piping or devices, which provide the spectators with a special effect such as water or air in accordance with a film screening state, may be installed between the lower plate 31 and the upper plate 32.

Although not illustrated in the drawings, the devices or the actuators for implementing the aforementioned various types of special effects are operated by a control operation of a control unit disposed in a control room of a film screening system in accordance with a film screening state.

The cover unit 40 may be installed at a front side, both lateral sides, and a rear side of a portion between the lower plate 31 and the upper plate 32 in order to protect various types of devices installed between the lower plate 31 and the upper plate 32, and improve convenience for the spectators.

According to the exemplary embodiment of the present disclosure, footrest portions may be installed at a front side of the cover unit 40 of the chair assembly 100 in order to ensure safety of the spectators and improve convenience for the spectators when the chair assembly 100 is operated by the drive unit 30, but the present disclosure is not necessarily limited thereto.

The fixing plates 300 may be formed at predetermined intervals in a horizontal and longitudinal direction of the lower plate 31 at both lateral sides of the lower plate 31 in order to fix the lower plate 31 to the ground.

A part of an upper end surface of the lower reinforcing plate 310 is in contact with a part of a lower end surface of the lower plate 31, and is formed in the lower plate 31 so as to correspond to a shape of the lower plate 31. The lower plate 31 and the lower reinforcing plate 310 may be integrally formed, but the present disclosure is not necessarily limited thereto. In addition, the lower plate 31 and the lower reinforcing plate 310 may be separately formed, and then may be fastened to each other by bolting, riveting, or welding, as necessary.

As illustrated in FIGS. 7 and 8, according to another exemplary embodiment of the present disclosure, the special effect sensory chair assembly 100 may further include a supporting plate 320.

The supporting plate 320 may be formed under the lower reinforcing plate 310 so that a part of an upper end surface of the supporting plate 320 is in contact with a part of the lower end surface of the lower reinforcing plate 310, and supports the actuator 33 or the spline device 34. That is, the supporting plate 320 is not formed at all portions under the lower plate 31, but may be formed under a portion of the lower plate 31 where the actuator 33 or the spline device 34 is installed, and a weight load or a fatigue strength is increased due to a weight of the actuator 33 or the spline device 34. Accordingly, costs required to manufacture the special effect sensory chair assembly 100 may be reduced, and desired strength may be reinforced.

That is, a portion of the lower plate 31, which is provided in the drive unit 30 of the special effect sensory chair assembly 100 according to the present disclosure, and where the actuator 33 or the spline device 34 is not installed, is formed to have a double structure by the aforementioned lower reinforcing plate 310, and a portion where the actuator 33 or the spline device 34 is installed is formed to have a triple structure by the lower reinforcing plate 310 and the supporting plate 320. Therefore, the special effect sensory chair assembly 100 according to the exemplary embodiment of the present disclosure may prevent the lower plate 31 from being damaged or bent by a weight load or a fatigue load, thereby reducing costs for maintenance of the chair assembly.

As illustrated in FIGS. 7 and 8, according to another exemplary embodiment of the present disclosure, the special effect sensory chair assembly 100 may further include a plurality of nuts 330 which is formed integrally with the lower end surface of the supporting plate 320 by welding.

Therefore, the actuator 33 and the spline device 34 may be fastened to the lower plate 31, the lower reinforcing plate 310, and the supporting plate 320 by bolts. The plurality of nuts 330 to which the bolts are fastened may be coupled to the lower end surface of the supporting plate 320 by welding, thereby reinforcing overall strength of the lower plate.

A special effect sensory chair assembly 100 according to another exemplary embodiment of the present disclosure will be described with reference to FIGS. 3, 4, 6, and 9. The special effect sensory chair assembly 100 according to another exemplary embodiment of the present disclosure may include a drive unit 30, chairs 20, a cover unit 40, and an upper reinforcing plate 350.

Since configurations of the drive unit 30, the chair 20, and the cover unit 40 are identical to those of the special effect sensory chair assembly 100 according to the aforementioned exemplary embodiment of the present disclosure, the upper reinforcing plate 350 will be concentratedly described hereinafter.

As illustrated in FIGS. 3, 4, 6, and 9, the upper reinforcing plate 350 may be formed in the upper plate 31 so that a part of an upper end surface of the upper reinforcing plate 350 is in contact with a part of a lower end surface of the upper plate 32, and formed to correspond to a shape of the upper plate 32. According to another exemplary embodiment of the present disclosure, the upper plate 32 and the upper reinforcing plate 350 may be integrally formed. However, the upper plate 32 and the upper reinforcing plate 350 may be separately formed, and then the upper plate 32 and the upper reinforcing plate 350 may be fastened to each other by bolting, riveting or welding, as necessary.

The upper plate 32 receives a weight load less than a weight load applied to the lower plate 31, and is installed above the lower plate 31, and as a result, the upper reinforcing plate 350 is not formed at a portion where strength reinforcement according to a load is not required. That is, the upper plate 32, which is provided in the drive unit 30 of the special effect sensory chair assembly 100 according to the present disclosure, may be formed to have a double structure by the upper reinforcing plate 350. Therefore, the special effect sensory chair assembly 100 according to the exemplary embodiment of the present disclosure may reinforce strength of the upper plate 32, thereby preventing the upper plate 32 from being damaged or bent by a weight load or a fatigue load, and reducing manufacturing costs.

A special effect sensory chair assembly 100 according to yet another exemplary embodiment of the present disclosure will be described with reference to FIGS. 4, 5, and 11. The special effect sensory chair assembly 100 according to yet another exemplary embodiment of the present disclosure may include a drive unit 30, chairs 20, a cover unit 40, water injection nozzles 200, a water line 220, and a solenoid valve 230.

One end of the water line 220 may be connected to the water injection nozzle 200, and the other end of the water line 220 may be connected to a water supply source 210. In the exemplary embodiment of the present disclosure, the water supply source 210 may be a public water supply facility or a water tank, but the present disclosure is not necessarily limited thereto.

The solenoid valve 230 is installed on the water line 220. Although not illustrated in the drawings, the solenoid valve 230 is connected to a seat controller which receives a signal from the control unit disposed in the control room of the film screening system, and the water injection nozzle injects water by a control operation of the seat controller according to a signal from the control unit.

The water regulator 240 may be installed on the water line 210. More specifically, the water regulator 240 may be installed between the solenoid valve 230 and the water supply source 210.

Although not illustrated in the drawings, according to another exemplary embodiment of the present disclosure, a flow rate control valve or an electronic proportional pressure reduce (EPPR) valve is installed between the solenoid valve 220 and the water injection nozzle 200, and may differently control an amount of water injected from the water nozzle by the seat controller which receives a signal from the control unit to which a time code for synchronization with a film screening state is input. That is, in a case in which it rains in the film screening state, a rain effect may be implemented by increasing an amount of water injected from the water injection nozzle, and in a case in which it is foggy in the film screening state, a fog effect may be implemented by decreasing an amount of water injected from the water injection nozzle.

Therefore, the special effect sensory chair assembly according to the present disclosure maximizes a rain effect using the water injection nozzle which is installed at the rear side of the seat portion so as to be directed toward a ceiling, thereby providing the spectators with an optimum effect according to the film screening state, and increasing interests of the spectators.

In addition, although not illustrated in the drawings, according to another exemplary embodiment of the present disclosure, an on-off switch may be provided in the chair assembly in consideration of preference of the spectator. That is, the spectator, who does not want the rain effect, may prevent water from being injected from the water injection nozzle according to a movie situation, by using the on-off switch. The on-off switch may be installed on the armrest portion so as to allow the spectator to easily manipulate the on-off switch.

A special effect sensory chair assembly 100 according to yet another exemplary embodiment of the present disclosure will be described with reference to FIGS. 5 and 12.
