Description

[Detailed Description of the Invention] This invention is intended to overlap the front and back door panels of a flush door and connect the side edges on both sides in the longitudinal direction with a plurality of retaining members.

To manufacture fittings such as the above-mentioned flush door, there are two methods: drilling holes in the aggregate and door panel at both ends and fixing them with rivets or screws, as shown in Figure 1, or welding the aggregate and door panel together and sanding. There is a way to finish it.

The former requires time and effort and has defects in which rivets or screws can be seen on the outside, while the latter has defects such as welding distortion and requires advanced techniques for sanding, making it unusable for decorative metal plates.

Furthermore, there are some types in which some welding is performed when assembling a combination of aggregates, but these have the latter defect mentioned above.

Therefore, this invention is designed to make it possible to manufacture fittings simply and reliably by interlocking a plurality of aggregates without the need for riveting, screwing, or welding.

To explain this invention with reference to an embodiment, as shown in FIGS. 2-3 and 7, both longitudinal edges of the front door panel 1 and the back door panel 2 are bent inward to form a U-shaped cross section.

The frame fitted between the front door panel 1 and the back door panel 2 is shown in Figs. 4 and 5, and the horizontal aggregates 3, 3' arranged at the upper and lower edges of the flush door have a cross-sectional shape. The longitudinal aggregates 4, 4', which are bent into a shape and placed on both the left and right sides, are bent into a cross-sectional shape, and the horizontal aggregates 3, 4' are bent into a shape.
3' and the vertical aggregates 4, 4' are respectively welded to form an integral frame, and within the frame formed by the horizontal aggregate 3゜3' and the vertical aggregates 4, 4'. A core material 6 such as a roll core, honeycomb, or foam material is housed in the front door panel 1 and the back door panel 2.
As shown in FIG. 6, the panel support aggregate 5, which is bent into a cross-sectional shape with the same length as the vertical aggregate 4, is sandwiched between the vertical aggregate 4 and the vertical aggregate 4 of the front door panel, as shown in FIG. In addition, by inserting the panel support aggregate 5' between the back door panel 2 and the vertical aggregate 4', this structure is secured as one piece.

In the above, the vertical aggregates 4 and 4' are fixed upside down to both ends of the horizontal aggregate 3゜3' as shown in Fig. 7, and the lower U-shaped part a is the front side or the back side in the cross section. The U-shaped cross-sectional portions of the door panels 1 and 2 are shaped to be fitted inside, and the upper hook-shaped portion C is overlapped as shown in FIG. There is.

The panel support aggregate 5 has an upper opening part d shown in FIG. 6, a U-shaped part of the front or back door panels 1 and 2, and an upper hook part C of the vertical aggregate 4 as shown in FIG. The lower L-shaped part e is in contact with the inner bottom of the U-shaped part a of the vertical aggregate 4, and the horizontal stepped part f between parts d and e is the front or rear door panel 1, 2. It has a shape that fits inside the horizontal part of the tip of the U-shaped part.

7 in FIG. 4 is the metal attachment part of the door bundle.

Figures 7 through 10 show the order in which the horizontal aggregates 3, 3', vertical aggregates 4, 4' are assembled with the front door panel 1 and the back door panel 2. As shown in FIG. 5, a frame made up of horizontal aggregates 3, 3' and vertical aggregates 4, 4' is assembled into a back door panel 2 as shown in FIG.
8, put the frame in contact with the inside of the back door panel 2, push it to the left, and assemble as shown in FIG. 9. Next, assemble the front door panel 1 as shown in FIG. 10. It is something.

Then, as shown in Fig. 2, panel supporting aggregates 5°5' are inserted between the front door panel 1, the back door panel 2, the horizontal aggregates 3, 3', and the vertical aggregates 4, 4'. ,
Each aggregate is locked to each other and brought into close contact with each other.

In order to prevent the supporting aggregate 5 from slipping out, the vertical aggregates 4, 4' and the panel supporting aggregate 5°5' are caulked at the insertion part by caulking the ends of the panel supporting aggregate 5°5'. By fixing it, there is no need for rivets or screws as shown at both ends of FIG. 1, and there is a feature that it is possible to easily manufacture a flush door that does not require welding or sanding.

As mentioned above, this invention has the advantage that a flush door can be easily assembled by integrating the left and right vertical aggregates into the front and back door panels and inserting a pair of panel support aggregates therein.
