BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter fixing device for fixing a filter to a receiving member, and more particularly, to a filter fixing device provided with an outer frame made of a frame member having rectangular projections on both longitudinal sides of a substrate. The present invention relates to a filter fixing device.

[0002]

2. Description of the Related Art Conventionally, a filter fixing device for fixing a filter to a receiving member is, as shown in FIG.
The bottom surface 20a of the filter abuts on a receiving member 22 provided on the ceiling via a gasket 21, and an abutment tool 24 attached to a bolt 23 erected on the receiving member 22 abuts on an upper surface 20b of the filter 20. The filter 2 is tightened by tightening the fitting 24 toward the receiving member 22.
0 is pressed and fixed to the receiving member 22.

[0003]

However, in the case of the above-mentioned conventional filter fixing device, the abutment 24 is attached to the filter 2.
0, the end of the bolt 23 and the nut 25 are also disposed outside the upper surface 20b of the filter 20. For example, when a punching plate or a decorative plate is provided, There have been problems such as the protruding bolts 23 and nuts 25 being in the way. In addition, since the abutment 24 is merely brought into contact with the upper surface 20b of the filter 20, the filter 20 is freely moved in the horizontal direction, and the positioning of the filter 20 is complicated, and the mounting operation takes a long time. SUMMARY OF THE INVENTION An object of the present invention is to provide a filter fixing device which eliminates the disadvantages of the conventional filter fixing device.

In order to achieve the above object, the filter fixing device of the present invention is a filter fixing device provided with an outer frame comprising a frame plate having a pair of rectangular projections on both sides in a longitudinal direction, wherein a receiving member is provided. An upright shaft member, an abutment mounted rotatably in a direction perpendicular to the shaft member so as to be immersed in a recess in the gap between the rectangular projections, and Ri Do from member tightening tightening, the rectangular projecting
The opposing gap of the part and the thickness of the abutment are substantially the same size.
It is characterized by having. Further, it is preferable that the shaft member is a bolt, and the tightening member is a nut that can be screwed to the bolt.

[0005]

According to the filter fixing device of the present invention, the patch attached to the shaft member is immersed into the recess in the opposed gap between the rectangular projections of the outer frame of the filter and is tightened. The amount of movement in the horizontal direction is regulated to facilitate the positioning of the filter, and the position of the patch need not exceed the upper surface of the filter. There is no need to stand. Further, when removing the filter, the filter can be easily removed simply by loosening the tightening member and rotating the applicator, and removing the filter outward from the opposing gap of the rectangular projection.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a filter fixing device according to an embodiment of the present invention; In the drawing, reference numeral 1 denotes a filter, and a filter pack 4 is hermetically surrounded by an outer frame 3 composed of a frame plate 2 having hollow rectangular projections 2a on both sides in the longitudinal direction.

The back surface 1a of the filter 1 is in contact with a lattice-shaped receiving member 5 disposed on the ceiling, for example, via a gasket 6, and the filter 1 is turned around a shaft member 7 composed of bolts standing upright on the receiving member 5. The rectangular fitting 8 movably attached to the outer frame 3
Of the shaft protruding portion 2a into the opposing gap 9, and a fastening member 10 formed of a nut is fastened to the screw portion 7a of the shaft member 7 to be pressed and fixed to the receiving member 5.

The method of attaching the filter 1 by the fixing device will be described. The abutment 8 attached to the shaft member 7 is rotated to a position where it does not hit the filter 1 and
Is brought into contact with the receiving member 5 via the gasket 6, and in this state, the contacting tool 8 is rotated to be immersed in the opposed gap 9 of the rectangular projection 2 a of the outer frame 3 and positioned. After that, the fastening member 10 is tightened to complete the fixing operation. When removing the filter, the fastening member 1
After loosening 0, the fixing device can be released by rotating the applicator 8 to remove it from the opposing gap 9 of the rectangular projecting portion 2a of the outer frame 3, and the filter 1 can be easily removed.

In the above embodiment, the filter 1 is mounted on the receiving member 5 arranged on the ceiling. However, when the filter is mounted on a wall, or when the filter unit with a fan is assembled, the filter is mounted on a casing. It can also be used as a fixing means when attaching to a filter, and the use mode of the filter fixing device of the present invention is not particularly limited as long as it is used for fixing the filter.

Further, in the above embodiment, the contact gap 9 of the rectangular projecting portion 2a of the outer frame 3 is formed to have a narrow width of about 3 to 8 mm with respect to the width of the outer frame 3 of 50 to 150 mm. 8, the backlash of the filter 1 is reduced. However, the play of the filter 1 is reduced by increasing the thickness of the patch 8 without making the opposed gap 9 particularly narrow. You may make it. Further, the shape of the rectangular projecting portion 2a is not limited to the hollow shape as in the above-described embodiment. The shape is not particularly limited as long as it has strength and has the opposed gap 9.

Further, the shape of the contact member 8 is not limited to a rectangular shape as in the above-described embodiment, and
The shape is not particularly limited as long as the shape can be immersed in the space and can retreat out of the opposed gap 9 by the rotation.

[0012]

As described above, the filter fixing device of the present invention has an effect that the filter can be fixed without projecting the fixing device from the filter, and that the positioning of the filter is easy.
