Abstract
Description
The present invention relates generally to a device for carrying a vertical acoustic reflector for a concert stage for a concert or the like, and more particularly by allowing the weight frame portion for the center of gravity of the vertical acoustic reflector to be lifted from the floor with the operator's force alone. A new, non-powered acoustic reflector carrier with a simple and inexpensive structure which makes the task of carrying the acoustic reflector efficient and easy without the need for complicated means when using electrical or hydrodynamic power. .
In general, in an upscale concert hall, theater, stage, performance hall, etc., an acoustic reflector is installed in order to better transmit the music or sound being played to the seat 1 (see FIG. 1) where the audience is sitting. However, when the acoustic reflector is installed in a permanent form, there is a problem that the stage cannot be used for various other uses, and in recent years, there are many examples of using the portable

The present invention has been devised to solve the above-mentioned problems of the conventional vertical acoustic reflector conveying apparatus, and, for example, in carrying a vertical acoustic reflector for a stage for a concert or the like, it requires a complicated means required when using electric or hydrodynamic power. It is an object of the present invention to provide a new non-powered vertical acoustic reflector conveying device which is mechanically simple and inexpensive, and which makes it possible to efficiently and easily carry the vertical acoustic reflector.
This object is achieved by a non-powered vertical acoustic reflector conveying device provided according to the invention.
The non-powered vertical acoustic reflection plate conveying apparatus according to the present invention includes one main panel for acoustic reflection of a predetermined height and a pair of wing panels foldably coupled to the left and right sides of the main panel, respectively. An apparatus for lifting and transporting a foldable vertical acoustic reflection plate having a weight frame structure for holding a center of gravity at the bottom of the rear surface thereof, the device being insertable into a space between the weight frame structure and the floor from the lower end of the main panel. A frame having a wheel and a support leg for movement in the lower portion; A screw jack assembly mounted on the frame to lift and lower the weight frame structure from a floor; A lifting handle for manually controlling the screwjack assembly; And a handle that can be gripped by a user to manually move the frame.
In a preferred embodiment, the screw jack assembly comprises three screw jacks arranged at vertices of a triangular shape and a gearbox for simultaneously providing power to the three screw jacks from the lifting handle. do.
According to the present invention, in carrying a vertical acoustic reflector for a stage, for example, a concert, etc., a mechanically simple and inexpensive structure and a vertical acoustic reflector without the complicated means required when using electric or hydrodynamic power are required. The operation of transporting the food can be made efficiently and easily.
Hereinafter, with reference to the accompanying drawings illustrating a non-powered vertical acoustic reflection plate conveying apparatus of the present invention with a specific example as follows.
