Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling ventilating fan in which a ventilating fan main body having a fan inside is attached to an opening edge of a ceiling.

[0002]

2. Description of the Related Art As a ceiling ventilation fan of this type, there is one disclosed in Japanese Utility Model Publication No. 50-136949. In this structure, one side of the opposing edge portion of the lower part of the ventilation fan main body having a fan inside is pivotally rotatably attached to one side of the field edge as the opening edge portion of the ceiling by a hinge fixed with a screw, and The other side of the opposing edge portion of the lower part of the ventilation fan main body is screwed and fixed to the other side of the field edge.

In this case, when performing maintenance or inspection of the ventilation fan main body, the screw on the other side of the ventilation fan main body is removed, and then the ventilation fan main body is rotated toward the indoor side with the hinge as a fulcrum. This allows the ventilation fan body to be pulled out to the indoor side.

[0004]

However, in the above-mentioned conventional structure, although the ventilating fan main body can be pulled out to the indoor side at the time of maintenance or inspection, when it is desired to remove the ventilating fan main body for maintenance or inspection, the hinge is unscrewed. I had to remove it from the field by doing so, and the work was troublesome, and reattachment was also troublesome.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a ventilation fan for a ceiling in which the ventilation fan main body can be pulled out to the room side from an opening in the ceiling, and the ventilation fan main body can be easily removed and installed. There is.

[0006]

[Means for Solving the Problems] A first means is to install a ventilation fan main body having a fan inside at an opening edge portion of a ceiling, wherein one of facing edge portions at the opening edge portion is provided. Side of the ventilation fan main body, a hooked portion which is provided on one side of the opposing edges of the lower part of the ventilation fan body and which is rotatably and detachably hooked on the hanging alloy tool. The invention is characterized in that it is provided with a connecting means for detachably connecting the other side of the facing edge and the other side of the facing edge in the opening edge (the invention of claim 1).

According to a second means, in the first means, the hooking alloy tool has a hooking portion made of a round bar material, and the hooked portion has a hook-like shape with an open bottom. Further, the bending angle is characterized in that the hooked portion is set at an angle such that the hooked portion does not come off the hooked portion at a position where the ventilation fan body hangs down with respect to the hooked portion (the invention of claim 2). .

According to a third means, in the first means, the hooking alloy tool has a hooking portion made of a round bar member having one end fixed, and the hooked portion is attached to this hooking portion from the other end side. It is characterized in that it is formed in a cylindrical shape to be inserted and fitted (the invention of claim 3).

According to a fourth means, in the first means, the hooking alloy tool has a hooking portion formed in a substantially semi-circular shape whose upper side is open, and the hooked portion is formed of a round bar. However, it has a feature (the invention of claim 4).

A fifth means is the same as the first means, wherein the connecting means is a hooked connected portion provided on the other side of the facing edges of the lower part of the ventilation fan main body, and the facing edge at the opening edge. And a fastener provided with the other side of the engaging member for detachably engaging the connected portion and a toggle type lever for holding the engaging member in the engaged state. There is a feature in that (the invention of claim 5).

According to a sixth aspect of the present invention, in the third means, the hooking portion of the hooking alloy tool is formed longer than the hooked portion, and has a protruding convex portion on the outer surface of the tip end thereof. The portion has a concave groove portion that can be fitted with the convex portion over the entire length, and inserts the engaged portion into the engaging portion in a state where the concave groove portion matches the convex portion, and the convex portion of the engaged portion It is characterized in that it is exposed from the end and then the engaged portion is mounted in a rotated form (the invention of claim 6).

[0012]

In the first means, the connection by the connecting means is released, and the ventilation fan main body is rotated about the hanging alloy tool as a fulcrum, so that the ventilation fan main body is pulled out to the indoor side from the opening. Also, since the engaged part is removable with respect to the hanging alloy tool, the ventilation fan main body can be easily removed from the ceiling by removing the engagement of the engaged part, and the ventilation fan main body can be attached to the opening edge part. Is the reverse procedure to the above,
The ventilation fan body can be attached to and detached from the opening edge of the ceiling with a simple operation.

In the second means, the hooking alloy tool has a hooking portion made of a round bar material, and the hooked portion has a hook-like shape with its lower part open, and the bent portion. The angle is

Since it is formed in a tubular shape, even if the ventilation fan body is hung down, the engaged part does not come off from the hanging alloy tool, and it is convenient for maintenance and inspection while the ventilation fan body is hung down. Moreover, since the engagement cannot be disengaged unless the engaged portion is pulled out from the hanging alloy tool, the engaged portion does not inadvertently disengage from the hanging alloy tool.

In the fourth means, the hooking alloy tool has a hooking portion which is formed in a substantially semi-arcuate shape whose upper side is open, and the hooked portion is formed of a round bar material. , Even if the ventilation fan body is hung, the hooked part does not come off from the hanging alloy tool, it is convenient for maintenance and inspection while the ventilation fan body is hung, and it is easier to remove and install. .

In the fifth means, the connecting means is a hook-shaped connected portion provided on the other side of the opposing edges of the lower portion of the ventilation fan body and the other side of the opposing edges of the opening edge. And a fastening tool provided with a toggle-type lever that holds the engaging member in an engaged state, and is simple. Therefore, the ventilation fan main body can be more easily removed and installed.

In the sixth means, the hooking portion of the hooking alloy tool is formed longer than the hooked portion, and the tip end of the hooking portion has a convex portion for preventing the pulling-out of the hooked portion. Has a recessed groove portion that can be fitted with the portion, and the engaged portion is inserted into the engaging portion in a state where the recessed groove portion matches the convex portion to expose the convex portion from the end portion of the engaged portion. After that, since the engaged portion is mounted in a rotated form, the convex portion can come into contact with the end portion of the engaged portion, so that the engaged portion can be relatively retained. .
