Description

Projector booth system

The present invention relates to a projector booth system, and more particularly, a booth capable of installing a projector in a movie theater is installed on a ceiling of a movie theater, and can be lowered for maintenance, so that the structure of a movie theater is more efficiently designed And more particularly, to a projector booth system that can optimize space utilization.

Generally, a movie theater includes a projection room in which a motion picture projector for reproducing an image of a movie film continuously on a screen to reproduce the image, and an image projected from the projector, Which can be watched through the screen.

Conventionally, a generalized projector projects an image of a motion picture film instantaneously analyzed and recorded on a screen continuously on a screen, and reproduces a screen as if motion is continuously performed using a residual image phenomenon of the eye And allows viewers to enjoy the images and sound of successive scenes through the screen.

However, when a conventional projection screen is used 30 times, the screen is shaken and the sound quality is deteriorated due to defective cleaning of the film and contamination due to foreign substances. In recent years, such problems have been solved, and a large- Digital light processing (Digital Light Processing) is becoming popular in order to enjoy high quality and high quality movies that are the same as the original regardless of the number of screenings from anywhere.

Such a digital projector (DLP) is made by filming and editing 35 mm film as before, but after the original is completed, it is converted into digital information using a digital copying machine called telecine and transferred to a magnetic tape or a digital disk, This is displayed on a screen through a digital projector, and can be said to be a method such as a CD or a DVD player.

On the other hand, since the projection room should be located at the back of the grandstand so that the projection room is positioned higher than the grandstand, there is a limit to the space utilization according to the design of the movie theater. That is, there is a disadvantage that the utilization of space is considerably lowered.

A method of installing the projector booth system according to the present invention in a movie theater will be described.

First, a base frame 210 is installed on a floor surface adjacent to a wall W of a movie theater. At this time, it is important that the center of the base frame 210 is set to coincide with the center of the screen.

The vertical frame 220 is installed on both sides of the base frame 210 installed as described above. At this time, the vertical frame 220 should be installed at an interval d of 20 mm from the rear wall W, and the length of the vertical frame 220 is cut to a size suitable for a work site.

Here, the vertical frame 220 is installed so as to form the interval d from the rear wall, so that the vertical frame 220 can be stably lifted without shaking.

The upper frame 230 is installed on the upper part of the vertical frame 220 and the both ends of the screw shaft 240 are supported on the central part of the upper frame 230 and the center part of the base frame 110. At this time, the screw shaft 240 should be installed so as to rotate in place, so that bearings are preferably installed at both ends.

A vertical bar 290 and an interior panel fixing bar 286 are installed between the vertical frames 220 installed at both sides of the base frame 210.

A screw guide 260 is installed on the screw shaft 240 and a lift member 270 is fixed to the screw guide 260. At this time, guide rollers 276a and 276b are installed at both ends of the lift member 270 so as to be guided by the vertical frame 220.

A drive motor 250 is installed on the upper frame 230 by using a bracket and a chain coupling to rotate the screw shaft 240 and electric wiring and the like are installed and the booth unit 100 Is provided on the lift member 270. [

In addition, the interior finishing unit 280 is installed to close the front of the frame. The interior finishing unit 280 may be installed before the booth unit 100 is installed. That is, if the booth unit 100 is installed, it may be difficult to install the interior finishing unit 280.

When the booth unit 100 is installed, the cover 112 may be fixed to the ceiling. That is, when the cover 112 is fixed to the ceiling, only the lower plate 114 is raised and lowered by the lift member 270.

Thereafter, the ventilation unit 130 is installed in the booth unit 100, and the interior of the booth unit 100 is closed to complete the installation of the projector system of the present invention.

In addition, in the present invention, the lift member 270 and the lower plate 114 are configured to support the projector, so that there is no warpage.

According to the projector booth system of the present invention configured as described above, when the digital projector is used recently, it is unnecessary for the projection room to be present in the movie theater, and unnecessary projection room is removed, and the structure of the movie theater can be designed more efficiently, .

Particularly, the present invention is characterized in that the booth unit 100 is lifted up and used only during movie screening, and when the maintenance and repair of the projector (replacement of the stove) is necessary, the booth unit 100 can be lowered.

Although the present invention has been fully described in connection with the preferred embodiments thereof with reference to the accompanying drawings, it is to be understood that the present invention is not limited thereto. It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
