The inner frame member 5 is formed into a cross-sectional shape of a vertical piece 5A having a length corresponding to the vertical piece 3A of the outer frame member 3 and an edge piece 5B.

Further, on the lower side of the surface of the vertical piece 5A facing the outer frame body 2, there are opposing locking protrusions 5C and 5D each having a hook-shaped cross section and substantially corresponding to the recessed part of the recessed part 3C of the outer frame member 3. A groove-shaped groove portion 5E is formed in a protruding manner along the longitudinal direction.

The inner frame member thus formed is framed in a rectangular shape with its groove portions 5E facing outward, thereby forming the inner frame body 4.

Support fittings 8 of hanging fittings 7, which will be described later, are attached to opposing positions near both ends of the pair of opposing outer frame members 3a and 3b of the outer frame body 2 formed in this way, and are opened on the ceiling 6. At the same time, a hanging rod 9 is fitted into the opening W, and a hanging rod 9 is fitted into the supporting metal fitting 8, and the hanging rod 9 is suspended from a ceiling structure member 11 installed in the attic space through the hanging rod 9. There is.

Moreover, the edge piece 3B extending to the outside of the outer frame member 3 is connected to the ceiling part 6.
is in contact with the bottom surface of.

Further, the inner frame body 4 is assembled to the outer frame body 2 so as to be opened and closed by an appropriate opening/closing means (not shown), and
A cover plate 6A of the same quality as the ceiling part 6 is attached to the inner frame body 4 in a fit-in manner.

Next, the above-described suspension fitting 7 will be described in detail. This suspension fitting 7 includes a support fitting 8 attached near both ends of the opposing outer frame members 3a and 3b of the outer frame body 2, and
It is constituted by a rod-shaped hanging rod 9 that is engaged in a fitting manner with the hanging rod 9, and a pair of locking members 10 that are inserted through the hanging rod 9.

This support fitting 8 is formed by cutting a long member M extruded from a light alloy material such as aluminum into a predetermined length, and its cross-sectional shape is the same as that of the mounting piece 8A of a predetermined length. The upper end of the piece 8A is bent into a cylindrical shape as shown in the figure, and the receiving part 8B
is formed, and the distal end portion 8C and the upper end portion of the attachment piece 8A are spaced apart from each other by a predetermined distance to form a groove 8D.

Further, on one surface 8E side of the mounting piece 8A, there is a protrusion 8F having a predetermined protruding length along its longitudinal direction.

8G is installed protrudingly.

The elongated member M thus formed is cut to a predetermined length L of the support fitting 8, and one end of the receiving portion 8B is cut out C1 as shown in FIG. , 8
G has notches C2 and C2 as shown in the figure to form the mounting protrusion 8F.
', gG' are formed to form the support fitting 8.

When attaching the support fitting 8 formed in this manner to the outer frame body 2, mounting holes are provided in the attachment portions at both ends of the outer frame members 3a and 3b through which the attachment protrusions 8F't 8G' of the support fitting 8 can be inserted. 3D is penetrated, and the mounting protrusions 8F' and 9G' are caulked to the outer frame members 3a and 3b, so that the support fitting 8 is integrally attached.

The suspension rod 9 is vertical and has a mounting part 9A having a threaded part 9B at the top, and the lower end of the metal part 9A is bent at a right angle to form a horizontal part 9C, and the tip of the horizontal part is bent at a right angle. Further, an insertion portion 9D is formed which is bent at right angles in the horizontal direction,
As shown in the figure, a retaining protrusion 9E is integrally provided at the distal end of the insertion portion 9D.

This retaining protrusion 9E is formed to a thickness that allows it to be inserted into the strip 118D of the support fitting 8, and the length of the insertion portion 9D is approximately equal to the length of the molded portion of the retaining protrusion 9E than the length of the receiving portion 8B. It is formed into a long shape.

Therefore, the insertion portion 9D can be inserted into the receiving portion 8B only when the retaining protrusion 9E is fitted into the groove 8D. 1
It becomes possible to rotate only when it is removed from D, and this rotation causes it to abut and engage with the edge of the receiving portion 8B, thereby preventing the hanging rod 9 from coming off.

In this way, the support fitting 8 and the hanging rod 9 are formed so that they can be engaged with each other and detached from each other.

Further, the locking members 10, 10 are formed with a substantially U-shaped cross section,
Wing nuts 12 and 12 are inserted through the threaded portion 9B of the hanging rod 9, sandwich the ceiling structural member 11 from above and below in opposing directions, and are screwed onto both sides of the locking members 10, 10 of the threaded portion 9B. By tightening, the hanging rod 9 is tightened to the ceiling structural member 11 via the locking members 10, 10, and the outer frame 2 is suspended.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the suspension fitting 7 of this example can be detachably connected to the support fittings 8 attached to the left and right ends of the pair of opposing frame members 3a and 3b of the outer frame body 2 formed in a rectangular shape. It consists of a hanging rod 9 that is inserted and engaged, and the support fitting 8 is attached to its mounting piece 8A.
A substantially cylindrical receiving portion 8B is integrally formed at the upper end, and an end 8C of the cylindrical receiving portion 8B is spaced apart from the upper end of the mounting piece 8A at a predetermined distance to form a groove 8D. On the other hand, an insertion part 9D is integrally formed at the end of the mounting part 9A having the threaded part 9B of the hanging rod 9, which can be inserted into the receiving part 8B and rotated, and has a retaining protrusion 9E at the tip. When the insertion portion 9D is inserted into and rotated with respect to the receiving portion 8B, the retaining protrusion 9E of the insertion portion 9D abuts and engages with the end surface of the receiving portion 8B.

Therefore, the suspension fitting 7 of this example has its support fitting 8 and suspension rod 9.
By attaching only the support fitting 8 to the outer frame 2 in advance, installation to the opening W of the ceiling portion 6 can be performed using the support fitting 8, as with conventional hanging fittings. Compared to a structure in which the and hanging rod are integrated, the hanging rod does not become an obstacle, and the work can be carried out extremely labor-savingly.

Furthermore, although the suspension of the outer frame 2 may differ depending on the form of the ceiling structural material 11, this can be handled by preparing suspension rods 9 with different lengths of the suspension rods 9 in the mounting portions 9A. It has many features.

The support metal fitting 8 illustrated in this example has protrusions 8F and 8G protruding from its mounting piece 8A, and this is cut out C2 to form mounting protrusions 8F' and 8G'. However, the invention is not limited to this, and as shown in FIG. 6, instead of the protrusions 8F and 8G, a thick portion 8H may be formed on the opposite side as shown in the figure and screwed to the outer frame 2. Good too.

In this case as well, the support fitting is formed from a long member.

Further, each of the frame members illustrated in the above embodiments is all shaped by a molded material extruded from a light alloy material such as aluminum.

The present invention consists of a support fitting attached to the left and right ends of a pair of opposing frame members of a rectangular outer frame body, and a hanging rod that is removably inserted and engaged with the support fitting. , the support fitting integrally has a substantially cylindrical receiving portion at the upper end of the mounting piece, and the end of the cylindrical receiving portion is spaced apart from the upper end of the mounting piece by a predetermined distance. forming a groove, and on the other hand, an insertion part is integrally formed at the end of the mounting part having the threaded part of the suspension rod, which is insertable into the receiving part and rotatable, and has a retaining protrusion at the tip; Insert the insertion part of the hanging rod into the receiving part.
When the insertion part is rotated, the retaining protrusion of the insertion part abuts and engages with the end face of the receiving part, making installation into ceiling openings such as ceiling inspection holes extremely labor-saving. It can be hung reliably, and it can be handled very easily by changing only the hanging rod according to the type of ceiling structure, so it is extremely practical as a hanging fitting for ceiling inspection openings, etc. This is a new idea.
