Abstract
PURPOSE:To make it possible to replace a filter without using a tool and with ease and simply as well by fixing a filter which is fitted into a mounting frame by means of a fastening device which makes a fastening device consisting of a strap, tape, etc., engageable and removable by the operation with the tip of a finger. CONSTITUTION:A main filter 7 is constructed by filling a filter into a rectangular frame 9 and it is fitted into a mounting frame 13 which is provided and projecting on the peripheral edge of a rectangular opening 12 opened through a shelf 2 of a room. The filter 7 is fixed by fixing both ends of a pair of bands 14 which are placed on the mounting frame 13 with an appropriate distance between them with a clamp 15. When the main filter 7 is replaced, it is released by lifting the clamp 15 by operating it by the tip of a finger. After each band is removed, the main filter 7 is pulled out from the mounting frame 13. Then a new main filter is installed in the reversed steps, namely after the main filter is fitted into the mounting frame the bands are placed on the frame and their ends are fixed by a clamp. And, the top plate 1b is closed, and it is tightened by small machine screws 24 to fix it.
