Description

[Detailed description of the invention] The present invention involves attaching the outer frame of the ceiling hatch, and extending the horizontal part of the hanging bracket with screw holes, which is attached to the channel using screw rods, in a direction parallel to the frame side of the outer frame. This relates to a characteristic ceiling hatch suspension device.

Conventionally, in this type of hanging device, there is an angle-shaped hanging fitting that is curved orthogonally to the side of the outer frame to which it is attached to form a horizontal part, and a screw hole is bored in the horizontal part. Normally, the hanging parts of the hanging fitting are attached to both ends of the hatch outer frame, the lower ends of screw rods screwed into the screw holes in the horizontal part of the hanging fitting are brought into contact with the mounting channel, and the screw rods are tightened. However, the outer frame of the ceiling hatch is expected to be relatively lightweight and tends to be weak, so when screws are strongly tightened at both ends of the mounting side of the outer hatch, the hanging of the opposing hatch outer frame as shown in Figure 4 is necessary. The screwing force of the screw rod acts on both ends (tightening parts) of the metal fitting side, and the screwing force causes the central parts of both mounting pieces to bend inward, causing problems in inserting into the inner frame or opening/closing operations. It does have its drawbacks.

However, in the present proposal, the horizontal part of the hanging bracket is extended in a direction parallel to that side beyond the other side perpendicular to the side of the hatch outer frame on which the hanging bracket is attached, and a screw hole is drilled in the extended part. Since the screw rod screwed into the screw hole is used to tighten the mounting channel, the tightening force acts in a direction parallel to the axis of the mounting side of the outer frame and eventually pulls it in the axial direction. This method has succeeded in eliminating the drawback of curving the mounting side, which is different from the tightening force of the previous method, and enables the installation of the outer frame of the ceiling hatch in a good manner without causing any trouble when inserting the inner frame of the ceiling hatch.

Now, referring to the accompanying drawings showing an example of the implementation of the present invention, reference numeral 1 shows the outer frame of a known ceiling hatch. Reference numeral 2 denotes a hanging fitting having a horizontal part 8 and a hanging part 9 vertically downward from the horizontal part 8;
As shown in the figure, the notches 10, 10 made from both sides of the lower part of the hanging part 9 are inserted into the notches 12 made on the side of the upper surface 11 of the hatch outer frame 1 from the inside of the hatch outer frame 1, and the hanging part 9 A stopper 13 with a drop 14 connected to the lower end is lowered as shown in FIG. 2, and a drop 14 is formed on the outer surface of the hatch outer frame 1 as shown in FIG. The hanging fitting 2 is attached to the inside of the hatch outer frame 1 and is fixed in a manner that it cannot be removed. 3 is an extension of the side end of the horizontal part 8 of the hanging fitting 2 in a direction parallel to the side 1a of the outer frame, beyond the other side 1b perpendicular to one side 1a of the hatch outer frame 1 to which the hanging fitting 2 is fixed. A step-shaped reinforcing portion 15 is provided at the side end of the extension portion 3 and the horizontal portion 8.
It is used to mold. 4 is a screw hole bored at the tip of the extension 3, and 5 is a butterfly-shaped headed screw rod that is screwed into the screw hole 4. Reference numeral 7 denotes a mounting channel installed and fixed on the upper surface of the field edge material 17 around the side of the ceiling hatch mounting opening 16. By bringing the lower end 6 of the screw rod 5 into contact with the channel 7 and tightening the screw rod 5, As shown in Figure 3, the outer edge 18 of the ceiling hatch outer frame 1 is brought into contact with the lower surface of the ceiling material 19, and the hatch outer frame 1 is brought into contact with the lower surface of the ceiling material 19.
is attached to the ceiling hatch attachment opening 16. 20 is a reinforcing strip formed across the base end of the extension portion 3, the horizontal portion 8 and the hanging portion 9;
is a cutout formed at the lower end of the hanging part 9 of the hanging fitting 2, which prevents the stopper 13 from coming out from the hanging part 9.
