摘要:
The present invention relates to a screen, and more specifically to a screen, to which a content images are projected, comprising screen regions each having a mutually different reflectance. According to the present invention, with respect to implementing a screen having a non-flat surface, as the content images can be projected onto all screen regions while maintaining uniform brightness, an audience can be provided with a content viewing environment by means of screens having a variety of shapes, while satisfactorily maintaining the quality of the of the projected a content images.

Disclosed is a device for supporting acoustical ceilings and other suspended objects. The device includes a clamp that is removably inserted into an outer sleeve. The exterior wall of the clamp includes threaded elements that can mate with threaded elements disposed on the interior wall of the outer sleeve so that the clamp can twist in and out of the outer sleeve in a screw-like manner. The clamp includes a cavity for securing a ceiling wire therein, wherein the ceiling wire can be attached to an overhead ceiling structure. The outer sleeve is removably secured to a ceiling grid. In use, the clamp can be repositioned within the outer sleeve to adjust the height of the ceiling grid. In this way, the present invention can be used in construction and commercial applications in a convenient manner, thereby simplifying the process of providing support for acoustic ceilings.

A clip assembly for a suspended ceiling having a ceiling panel and a runner comprises a top member and a bottom member. The top member has an upper wall for being secured to an overhead structure and a pair of lower spaced apart lateral walls downwardly extending from the upper wall. The lateral walls comprise respective outer surfaces and inner surfaces defining a channel therebetween. At least one inward fin extends from each of the inner surfaces into the channel in an upwardly sloped direction. The bottom member comprises a bottom end for being secured to the runner and opposite lateral surfaces therebetween. At least one outward fin extends from each of the lateral surfaces in a downwardly sloped direction that is complementary to the upward sloped direction of the at least one inward fin. The bottom member is inserted into the channel.

A saddle connector, having an inverted channel, engages a bulb of a beam in the grid of a suspended ceiling. The channel has hardened teeth staggered along the opposing walls of the channel. The teeth are forced into the bulb of the beam, one at a time, by the full force exerted by hand operated pliers.
