DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an explanatory view showing a projection system having a screen device and a projection device of the present invention, and FIG. 2 is a side view of the screen device.
The projection apparatus denoted as a whole by reference numeral 10 includes a projector 30 placed on a frame 20.
A caster 22 is attached to the lower part of the frame 20, and the projection apparatus 10 can be moved to an arbitrary position.
The screen device of the present invention, indicated as a whole by reference numeral 100, has a frame 110, and the frame 110 is assembled into a required shape by a structural member 112 such as a pipe and a joint member 114.
Four casters 130 are attached to the bottom of the frame so that the screen device 100 can be moved to an arbitrary position.
A casing 160 made of a board member is attached inside the frame 110.
The housing 160 includes a ceiling panel 161, a front panel 162, a back panel 163, and double-sided panels 165 and 166, and a floor panel 164 is provided in a necessary portion.
The front panel 162 of the housing 160 is formed with an opening having an appropriate size, and the speaker 150 is attached through the opening.
In this embodiment, three speakers 150 are shown, but the number of speakers equipped on the front panel is appropriately selected according to the size of the screen.
In addition, a heavy bass speaker 152 is also provided with a caster 154.
The screen 200 is fixed to the front frame 110 by a string 220 that is stretched around the screen 200.
The projection light R 1 from the projector 30 is projected on the screen 200 and displayed as a screen.
A casing 160 made of an appropriate board member is installed inside the frame 110, and a video / audio sending device 300 is placed on the floor panel 164 of the casing 160.
A speaker 150 is attached to the front panel 162 of the housing 160.
The screen 200 is fixed to the front frame 110 by a string 220 stretched around it.
An upper mask 270 is attached to the support member 170 attached to the upper part of the frame 110 to cover the string 220 and the like on the upper part of the screen 200.
The shaft member 250 is also supported on the frame at the lower end of the screen 200 via the attachment member 240, and the lower mask 260 is suspended from the shaft member 250.
Masks (not shown) are also attached to both sides of the screen 200 to cover structures around the screen.
A curtain rail 410 is attached to the front end portion of the support member 170, and the curtain 400 is suspended. The curtain 400 can be opened and closed from the center to the left and right, and also serves to protect the screen 200.
A one-character curtain 500 is suspended in front of the curtain rail 410.
【The invention's effect】
Since the screen device of the present invention is configured as a unit equipped with necessary equipment and is movable, it can be stored when not in use, and can be moved to a place of use and utilized as a projection screen only when necessary.
When moving over a long distance, the members can be disassembled and transported and assembled during use.
Further, by making the projection apparatus movable, a projection system with a higher degree of freedom can be configured.
