Description

Fixture and white board coupling structure having the same {FIXTURE AND COUPLING STRUCTURE OF WHITE BOARD INCLUDING SAME}

The present invention relates to a white board, and more particularly, to a fixture for fixing a frame of a white board and a white board coupling structure including the fixture.

In general, blackboards using chalk are mainly used in classrooms of schools or academies of various levels, but in recent years, whiteboards that can be written on using a water-based magic pen and erased using an eraser have been widely used.

In the conventional whiteboard, the whiteboard panel is fixed to a rectangular frame-shaped frame made of metal or wood such as aluminum, and when used indoors, it is difficult to see the contents written on the whiteboard without a separate lighting device. However, when a separate lighting device is installed, parts other than the whiteboard are also illuminated, which distracts attendees' attention.

In addition, even when a separate lighting device is installed, since the brightness of the lighting is not uniform across the entire surface of the white board, there is a problem in that recorded contents cannot be clearly displayed.

In order to solve this problem, a lighting device is installed inside the frame as shown in FIG. 1 and installed on an external electrical lead to supply power to the lighting device outside the frame. There is a disadvantage that it is not neatly arranged in .
