BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for storing a curtain box and a ceiling board, and relates to a curtain box with a ceiling board receiving curtain board capable of widening the curtain board with one touch according to the height of the ceiling. .

[0002]

2. Description of the Related Art A curtain box formed of an aluminum draw is provided with a reverse groove-shaped box body 5 as shown in FIG.
Vertical walls 52, 52 having a reference width hang down from both edges of the ceiling plate 51 of No. 0, a mounting rail 53 is formed on the lower surface of the ceiling plate 51, and a ceiling plate bent outward at the lower end of the vertical wall 52. The support edges 54 are integrally formed. Therefore, when adjusting the width H1 of the hanging wall 52 required in relation to the height of the ceiling plate S during construction, a widening curtain plate portion having a substantially L-shaped cross section on the lower edge side of the hanging wall 52 is conventionally used. At the upper end of 56, the edge 5 having a shape along the ceiling plate supporting edge 54 of the box body 50
8 to form a curtain plate member 55, and the curtain plate member 5 is connected.
The height H (= H1 + H2) of the curtain box is adjusted by selecting the effective width H2 of the widening curtain plate portion 56 of No. 5.

[0003]

Therefore, as a means for connecting and integrating the curtain plate member 55 with the box body 50 at the time of the above-described widening construction, one end of the fastener body 61 having a C-shaped cross section has been conventionally used. Fastening screw 62 that is screwed back and forth toward
The shackle type fastening member 60 formed by screwing the
And the edge 58 on the side of the curtain plate member 55 is fastened vertically to widen it. Therefore, not only the structure of the fastening member 60 is complicated and the material cost rises, but also the fastening screw 62 needs to be tightened at the time of construction, which causes not only poor workability but also poor fastening. It was

The present invention has been made in view of the above problems, and is composed of a curtain plate member and a fastening member for attaching the hanging wall of the box body with one touch, thereby reducing the material cost and improving the workability. It is an object of the present invention to provide a curtain box with a ceiling plate receiving curtain plate capable of achieving the above.

SUMMARY OF THE INVENTION A curtain box with a ceiling plate receiving curtain plate according to the present invention has a pair of hanging walls facing each other from both edges of a top plate, and a single or a plurality of mounting rails on the lower surface of the top plate. A ceiling plate support edge having an appropriate width that is bent at right angles to the outside is integrally formed at the lower ends of the hanging walls of the curtain box having the above-mentioned shape, and the edges are locked to the inner wall surface of the hanging walls in a hook shape in section. A box main body integrally formed with a locking rib having an L-shaped cross-section as an end downward, and a ceiling plate support edge having the same shape as the ceiling support edge of the box main body are formed integrally with the outside of the lower end of the widening curtain plate portion. A fastening plate integrally formed with a hook-shaped locking end at the front end of the widening curtain plate portion so as to be spaced apart from the lower surface of the ceiling plate supporting edge of the box main body and projecting in a substantially parallel manner outside the upper end of the widening curtain plate portion; Extends from the inner edge of the plate, The formed locking end and the connecting plate that constitutes the hook-shaped locking end that elastically engages are integrally molded, and the curtain plate member that is connected and widened under the hanging wall of the box body has a U-shaped cross section. An inwardly bent locking edge that engages with the reinforcing and upright edge of the box body, and an edge facing the locking edge is a slanted edge that is inclined outward. The gist of the present invention is that it comprises a short fastening member integrally formed with an engaging step portion that engages with the hook-like engaging end of the curtain plate member at the inner end of the facing edge.

[0006]

When the curtain box is widened, when the connecting plate of the curtain plate member is inserted into the locking rib of the box body and the hook-shaped locking end is engaged with the locking end, the bottom surface of the base end of the ceiling plate supporting edge is And the upper end abuts. In this state, the locking edge of the fastening member is engaged with the end of the box body and pushed in, and the locking step formed at the inner end of the oblique edge is engaged with the hook-shaped locking end of the curtain plate member. As a result, the width can be expanded with one touch.

An edge 24 is provided, and the hook-shaped locking end 1 of the curtain plate member 11 is provided at the inner end of the oblique edge 24.
A locking step portion 25 that engages with 6 is configured. Also reference numeral 2
Reference numeral 6 is a finger hanging rib.

In the curtain box with a ceiling plate receiving curtain plate having the above structure, the height H1 of the box body 1 is set to the curtain plate member 11
To obtain a desired height H by widening the width H2 by
The construction is shown in FIG. First, when the connecting plate 18 of the curtain plate member 11 is inserted into the locking rib 8 of the box body 1 and the hook-shaped locking end 19 is engaged with the locking end 9, the step structure 17 causes the step structure 17 to be the base end of the ceiling plate supporting edge 6. Contact the bottom of the part. Fastening member 2 in this state
The locking edge 23 of No. 1 is engaged with the reinforcing and standing edge 7 of the box body 1, and the finger hooking rib 26 is pushed in the direction of the arrow A, so that the locking step portion 25 formed at the inner end of the oblique edge 24 is formed. The structure is such that it engages with the hook-shaped locking end 16 of the curtain plate member 11.

The fastening member 21 is surely integrated by the elasticity of the thin fastening plate 15 protruding from the curtain plate member 11, and is properly spaced in the longitudinal direction (about 30 to 60 cm).
It is possible to obtain a sufficient strength to support the edge load of the ceiling plate S by mounting with.

[0015]

As described above, the curtain box with the ceiling plate receiving curtain plate according to the present invention uses the fastening member that constitutes the elastic locking structure made of a short piece of aluminum forging without using rivets or screws.
