Description

TECHNICAL FIELD The present invention relates to a structure for attaching an extension wall to a side plate of a box body in a curtain box or a blind box.

Conventional technology Conventionally, when attaching these extension walls to the box body, the height of the ceiling surface and the window opening differs depending on each construction site, so select the corresponding extension wall for adjustment,
It was fixed to both side plates of the box body with screws and rivets and attached to the ceiling surface.

However, in such a box extension wall mounting structure, positioning is performed at each construction site, holes for mounting are formed in both sides, and screws and rivets are used to secure the power tool. However, the workability was extremely poor because the holes were misaligned and the rivets did not enter.

An object of the present invention is to solve these drawbacks and to provide an attachment structure in which an extension wall is attached to the box body without using an electric tool and which is easy to position and has good workability.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a box extension wall mounting structure in which a top plate and a side plate have a substantially cross-section, and a box body provided with a hinge receiver on the side plate and a cross-section having a substantially L-shape. It consists of an extension wall with a locking piece at one end and a clip member with a screw at one end, a hinge at the center and a pressing piece at the other end. Is smaller than the distance between the hinge and the screw, the hinge of the clip member is pivotally attached to the hinge receiver of the box body, and while the locking piece of the extension wall is in contact with the side plate of the box body, the hinge is used as the fulcrum by screwing the screw. By rotating the clip member, the screw portion of the clip member is separated from the side plate, the pressing piece is pressed and fixed to the locking piece, and the extension wall is joined to the box body.

Effects Since the present invention has the above-described structure, when the side plate is pushed by screwing the screw of the clip member, one end of the clip member moves in the opposite direction to the side plate, but the pressing piece at the other end uses the hinge as a fulcrum. Since the lever is rotated, the lever moves to move toward the side plate. Moreover, since the distance from the hinge to the pressing piece is shorter than that to the screw, the pressing force becomes even stronger.

Therefore, the locking piece of the extension wall that is in contact with the side plate of the box body is strongly pressed against the box body by the pressing piece of the clip member, and the box body and the extension wall can be firmly fixed.

As shown in FIG. 1, the side wall of the box body may be directly brought into contact with the locking piece of the extension wall and pressed by the clip member.
As shown in FIG. 4, when the projecting piece is provided on the side plate and the locking piece is locked to the projecting piece and pressed by the clip member, the locking piece is sandwiched between the projecting piece and the pressing piece, so that the mounting is more effective. To be the target.

Further, the clip member may be formed as a molded product having the same cross section as shown in FIGS. 1 and 2, but as shown in FIG. 3, a plate member is slit and bent to form a hinge or a pressing piece. Good.

Embodiment An embodiment of the present invention will be described with reference to the drawings.

In the embodiment shown in FIGS. 1 and 2, the box body 1 is formed by a top plate 2 and both side plates 3 and 3 in a substantially cross-sectional shape, and a dovetail-shaped holding portion 4 opened upward on the outer surface of the top plate 2. Provided, both side plates 3,
A hinge receiver 5 having an U-shaped cross section is provided on the outer surface of 3 and is folded back downward, and a groove 6 is provided at the lower end of the side plate 3.

One end of the extension wall 7 is bent in a crank shape to form a locking piece 8 at the tip, and a standing piece 9 is provided at the base of the crank shape. At the lower end of the extension wall 7, there is provided a dovetail-shaped holding portion 10 that is open to the outside, and below that, a horizontal piece 11 that is bent outward in an L-shape is provided. The left extension wall 7 and the right extension wall 7 have the same shape except that the lengths thereof are different.

The clip member 12 has a thick wall at one end and a mountain shape at the center.
The other end is formed in the same rectangular cross section, a screw hole 13 is provided at one end, and the red inclined portion of the other end is used as a pressing piece 14, and the pressing piece 14 is provided at a position near the other end of the central portion. A hinge 15 is provided which is protruded to the side and folded back to the one end side. The hinge 15 is formed so as to be pivotally attachable to the hinge receiver 5 of the box body 1, and when the hinge 15 is pivotally attached to the hinge receiver 5, the extension wall 7 abutted against the side plate 3 of the box body 1 is provided. Locking piece 8
In addition, the tip of the pressing piece 14 abuts. In the screw hole 13 of the clip member 12, the screw 16 of the bolt is attached to the side plate 3 at the tip.
It is screwed so as to come into contact with, and a spring washer 17 is inserted and attached under the neck.

To attach the extension wall 7 to the box body 1, the side walls 3 and 3 of the box body 1 have extension walls 7 and 7 selected according to the construction site.
While inserting the upright piece 9 into the groove 6, the locking piece 8 is brought into contact with the outer surface of the lower end of the side plate 3.

Next, the hinge 15 of the clip member 12 is inserted into the hinge receiver 5 of the box body 1 and pivotally attached, and the tip of the pressing piece 14 is extended.
It is brought into contact with the locking piece 8 of. Further, when the screw 16 is screwed in and the side plate 3 is pushed, one end of the clip member 12 moves in the opposite direction to the side plate 3, so that the other end, that is, the pressing piece 14 rotates about the hinge 15 as a fulcrum, The locking piece 8 is pressed. At this time, since the distance from the hinge 15, which is the fulcrum, to the pressing piece 14 is shorter than the distance to the screw 16, the force applied to the pressing piece 14 becomes stronger due to the lever action, and the extension wall 7 and the box body 1 are not fixed to each other. It will be even stronger.

The box main body 1 and the extension wall 7 which have been attached have a rocking preventive metal fitting (not shown) inserted in the holding portions 4 and 10 thereof to prevent the rocking.

In the embodiment shown in FIG. 3, the clip member 12 is formed from a single flat plate, and two slits are provided, the central piece is deeply bent and folded back to form the hinge 15, and both side pieces are shallowly shaped. The pressing piece 14 is formed by bending it into a.

In the embodiment of FIG. 4, a protruding piece 18 is provided below the hinge receiver 5 of the side plate 3 of the box body 1, and the engaging piece 8 of the extension wall 7 is locked to the protruding piece 18. The locking piece 8 is pressed by the pressing piece 14 of the clip member 12.

In this case, since the locking piece 8 is sandwiched between the projecting piece 18 and the pressing piece 14, the mounting strength becomes more effective.

Effect of the Invention Since the mounting structure of the present invention firmly fixes the box body and the extension wall by the lever action of the clip member, an electric tool is not required at the construction site and it can be easily installed with only a spanner or screwdriver. became. Moreover, since there is no drilling work, positioning becomes easy,
The existing problems such as re-drilling without inserting rivets have been eliminated, and workability has improved significantly as a whole.
