Hereinafter, the configuration of the door panel 20 will be described in detail, and the features of the present invention will also be described. In the following description, for the sake of convenience, the terms "viewing direction" and "viewing direction" may be used. The prospective direction is the direction along the depth of the fittings, as indicated by arrow A in the drawing. A surface along the projection direction may be called a projection surface, and a dimension along the projection direction may be called a projection dimension. In the case of horizontal frames such as the horizontal frames 13 and 14, the viewing direction is a vertical direction orthogonal to the viewing direction. In the case of vertical frames 11, 12, etc., which extend along the vertical direction, the viewing direction is the horizontal direction perpendicular to the viewing direction. A plane along the viewing direction may be referred to as a viewing plane.

The aggregates 21, 22, 23, and 24 are formed by integrally forming a base plate portion 201 each having a flat plate shape and side plate portions 202 extending from both side edges of the base plate portion 201 in the same direction by bending at substantially right angles.

On the other hand, the substrate portions 201 of the longitudinal aggregates 21 and 22 are provided with fitting fin portions 205 at both ends on the surface on the inner peripheral side. The fitting fin portion 205 is a plate-like member extending in a direction perpendicular to the base plate portion 201, and has a width that allows it to be fitted into the guide slots 204 of the horizontal beams 23 and 24. . The aggregates 21 , 22 , 23 , 24 having these configurations are formed into a rectangular frame shape by fitting the fitting fins 205 of the longitudinal aggregates 21 , 22 into the guide slots 204 of the horizontal aggregates 23 , 24 . The structural frame 25 is constructed by assembling the parts and further welding them at appropriate points. As is clear from the drawing, the fitting fin portion 205 has a notch 205a at a portion corresponding to a drainage hole (engagement notch) 24a of a lower horizontal aggregate (hereinafter referred to as a lower aggregate 24), which will be described later. It is provided. Although FIG. 4 shows only the lower corner on the suspension side, the other corners are similarly constructed.

The surface members 26, 27 are formed by integrally forming a surface plate portion 206 having a rectangular flat plate shape and a bent portion 207 bending and extending from four sides of the surface plate portion 206 in the same direction at a substantially right angle. It is. The bent portion 207 is constructed so as to have a projected dimension of approximately 1/2 of the base portion 201 of the aggregates 21, 22, 23, and 24. When arranged, it is possible to cover the substrate portion 201 of the aggregates 21, 22, 23, 24 without overlapping each other.

The hinge 30 described above has mounting holes 31 at its four corners. By screwing a screw S into the base plate portion 201 of the vertical frame 22 via 207, it is fixed to the projection surface 20b of the door panel 20 on the hanger side. As is clear from FIG. 3, in the present embodiment, hinges 30 are attached to the upper portion, the lower portion, and the upper middle portion of the door panel 20, respectively.

A corner cap (cap member) 40 is attached to the lower corner of the door panel 20 on the hanger side. As shown in FIG. 5, the corner cap 40 includes a lower cover portion (cover portion) 41 that covers a prospective surface 20a that is the lower surface of the door panel 20, and side covers that cover a prospective surface 20b located on the hanger side of the door panel 20.

Become. For this reason, there is no possibility that the engaging piece 208 will return to its original position along the bent portion 207, and even if a larger external force is applied to separate the surface materials 26, 27, the surface materials 26, 27 will not be pulled apart from the lower aggregate 24. 27 is reliably prevented from moving.

Finally, by screwing the screws 45 into the longitudinal ribs 22 from the screw insertion holes 43a of the corner caps 40, the corner caps 40 are prevented from coming off the door panel 20, and the above state is maintained. . Although not shown in the figure, edge members 50 are provided over the entire length of the door panel 20 on the projected surface of the door panel 20 so that the bent portions 207 of the surface members 26 and 27 are sandwiched between the longitudinal aggregates 21 . installed.

According to the door panel 20 described above, the engagement of the engaging pieces 208 with the lower aggregate 24 allows the surface members 26 and 27 to be separated without riveting between the lower aggregate 24 and the surface members 26 and 27. Dropping and peeling can be prevented. As a result, as a result of eliminating the need for special equipment for riveting, the manufacturing cost of the door panel 20 can be reduced. Furthermore, the corner caps 40 cover the bent portions 207 and edge portions of the surface members 26 and 27, which is advantageous in terms of appearance quality. In the above example, the corner caps 40 are attached only to the lower corners of the suspension side, but the corner caps 40 can be similarly attached to other corners such as the upper corners of the suspension side. Of course it is good.

In the above-described embodiment, the entrance door supported by the frame 10 via the hinges 30 is exemplified, but the present invention is not limited to this. If it is configured by providing a surface material, respectively, it can also be applied as a surface material for a sliding door. In this case, it does not necessarily have to be for the entrance. Moreover, although the engaging pieces 208 of the surface members 26 and 27 are engaged with the lower aggregate 24 using the drainage holes 24a, the lower aggregate 24 may be provided with a dedicated engagement notch. I do not care. Incidentally, the engaging notch is not necessarily limited to one with an open end, and may be of course a hole-like one with a closed periphery. In this case, it is not always necessary to share the engagement notches for the two surface materials, and the engagement pieces of the respective surface materials may be engaged with independent engagement notches. Furthermore, although the insertion member 44 is inserted after the engagement piece 208 is engaged with the lower aggregate 24, the present invention is not limited to this. A configuration in which the engaging piece portion 208 is only bent and engaged with the lower aggregate 24 may be employed. In this case, it is preferable that the engaging piece portion 208 is not simply bent at a right angle, but is bent along the upper surface of the base plate portion 201 in the lower aggregate 24 . When inserting the inserting member 44, the inserting member 44 integrally formed with the corner cap 40 is applied in the above embodiment, but the inserting member may be simply inserted into the engagement notch. .
