By the way, for the purpose of improving the appearance, there is known a frame body (shoji) in which the surface of the base material of the frame body (shoji) is covered with a surface layer member having a color different from that of the base material. When such frames are welded and joined, as shown in Patent Document 1, the frames are butted against each other and joined by pressure bonding by thermal welding. At this time, at the time of thermal welding, the inner base material and the surface layer member swell from the bonding surfaces of the frames, and burrs are generated on the surface of the frame. When the burr is removed, the base material is exposed between the frames. Since the color of the base material and the color of the surface layer member are different, it becomes necessary to paint the exposed base material in the same color as the surface layer member. Since the exposed parts are painted by hand, it takes man-hours and material costs, which reduces production efficiency.

The present invention has been made in view of such problems, and an object of the present invention is to provide a frame and a method for manufacturing the frame that can improve production efficiency.

In the present invention, since the vertical frame and the horizontal frame are connected via the adhesive member of the same color as the surface layer member, it is possible to prevent the base material from being exposed between the vertical frame and the horizontal frame. That is, since the adhesive member is exposed between the vertical frame and the horizontal frame, it is not necessary to paint the exposed base material with the same color as the surface layer member as in the conventional art. Thereby, production efficiency can be improved. Moreover, according to the present invention, since it is not necessary to paint the exposed base material with the same color as the surface layer member, it is possible to suppress the occurrence of color unevenness and variations in the color of each frame. Therefore, quality can be improved.

Further, in the frame body according to the present invention, the vertical frame or the horizontal frame has a hollow portion inside, and the adhesive member includes a first extension portion extending along the surface layer member and the first extension portion. It may have a second extending portion that extends perpendicularly to the portion and is thicker than the plate thickness of the vertical frame and the horizontal frame.

Since the vertical frame and the horizontal frame have the second extension portion thicker than the plate thickness of the horizontal frame, the contact area between the vertical frame and the horizontal frame can be increased. Therefore, the vertical frame and the horizontal frame can be adhered more firmly.

Further, in the frame according to the present invention, at least one end surface of the vertical frame or the horizontal frame is formed closer to the inner side of the vertical frame or the horizontal frame than the surface layer member, and the adjacent vertical frame is formed on the inner side of the vertical frame or the horizontal frame. A stepped portion projecting toward the other side of the frame or the horizontal frame may be provided, and the adhesive member may be provided so as to cover the stepped portion.

Since the adhesive member is provided so as to cover the stepped portion, it is possible to more effectively suppress exposure of the base material from the surface of the surface layer member.

Since the adhesive member is arranged in the notch, exposure of the base material can be suppressed even on the side surfaces of the frame. Therefore, the trouble of coloring the exposed portion can be saved. In addition, since it is possible to prevent the adhesive member from protruding from the corners of the frame, material costs can be reduced.

In the method for manufacturing a frame according to the present invention, a pair of vertical frames extending in the vertical direction and a pair of horizontal frames extending in a direction orthogonal to the pair of vertical frames are connected to form a four-sided frame, and the vertical frames and The horizontal frame has a base material and a surface layer member formed on the surface of the base material and having a color different from that of the base material,

The projecting portion 35 extends above the first bonding portion 31A along the extending direction of the first bonding portion 31A. The projecting portion 35 is spaced apart from the first piece 33 and the second piece 34 . Thereby, a recess 36 is formed between the protrusion 35 and the first piece 33 and the second piece 34 . The depression 36 can be brought into contact with (placed on) the stepped portion 17 formed in the door-end vertical frame 13 .

Further, as shown in FIG. 7, each frame has a hollow portion S2 formed therein. Assuming that the dimension of the hollow portion S2 in the indoor/outdoor direction is L1 and the dimension in the extending direction of the first piece 33 and the second piece 34 is L2 as shown in FIG. And the dimension L2 of the second piece 34 is substantially the same, or the dimension L2 of the first piece 33 and the second piece 34 is slightly larger. As a result, the first piece 33 and the second piece 34 can be fitted into the hollow portion S2.
Assuming that the dimension of the notch 13e in the indoor/outdoor direction is L3 as shown in FIG. 7 and the dimension in the extending direction of the projecting portion 32A is L4 as shown in FIG. formed smaller. Thereby, when the adhesive member 30A is welded, the adhesive member 30A is configured to be buried in the notch portion 13e.

As shown in FIG. 10, the adhesive member 30A described above is arranged at the end portion 13a of the door tip side vertical frame 13 (adhesive member arrangement step).

The adhesive member 30 protrudes from the edge. Since the adhesive members 30 of the same color as the surface layer member 20 are arranged at both ends of the frame, the adhesive member 30 of the same color as the surface layer member 20 remains even if the protruding portion (burr) is cut off. not exposed. As a result, it is possible to save the cost and labor of painting the white portion exposed between the frames unlike the conventional method, so that the production efficiency can be improved.
Moreover, both ends 15a and 15b of the adjacent upper frame 15, both ends 16a and 16b of the lower frame 16, both ends 13a and 13b of the door leading side vertical frame 13, and both ends 14a and 14b of the hanging side vertical frame 14 Since the bonding members 30 are arranged respectively, the frames can be bonded to each other in a more uniform and stable state.

In the present embodiment, the adhesive member 30A is always arranged on the upper surface 17a of the stepped portion 17 by bringing the depression 36 into contact with the stepped portion 17 . As a result, exposure of the frame 11 from the surface 20a of the surface layer member 20 can be reliably suppressed. Further, by bringing the depression 36 into contact with the stepped portion 17, the adhesive member 30A can be arranged at a fixed position.
Furthermore, since the adhesive member 30A has the first piece 33 and the second piece 34, the frames can be connected more firmly.

That is, between the end 41a of the upper frame 41 and the end 43a of the vertical frame 43, between the end 43b of the vertical frame 43 and the end 42a of the lower frame 42, and between the end 42b of the lower frame 42 and the vertical frame 44 and between the end 44a of the vertical frame 44 and the end 41b of the upper frame 41, the upper frame 41, the lower frame 42, and the pair of vertical frames 43 are assembled. , 44 may be concatenated.
Further, the surface layer member 20 covers the surface 11a and the side surface 11b of the frame 11, but it is sufficient that it covers at least the surface 11a of the frame 11. FIG.
Although the surface layer member 20 is provided on the outdoor-side surface 11a of the frame 11, the surface layer member 20 may be provided on the indoor-side surface of the frame 11. may be provided with the surface layer member 20.

In addition, although the adhesive member 30 is configured to have the first adhesive portion 31 and the second adhesive portion 38, the adhesive member 30 is interposed between adjacent frames on the surface of the frame body 11 including at least the surface layer member 20. The second bonding portion 38 does not have to be provided because it is only necessary for the frames to be connected to each other in a state where the frames are connected to each other. Also, the first piece 33 and the second piece 34 may not necessarily be provided, or one of them may be provided.
Moreover, the structure which does not provide the step part in each frame may be sufficient. Even if each frame is not provided with a stepped portion, it is possible to prevent the frame body 11 from being exposed from the surface 10a of the shoji 10 by providing an adhesive member between each frame.
Notch 13e may not necessarily be formed.

In the present embodiment, the method of placing the adhesive members 30 on both ends of each frame and welding them is shown, but a method of placing the adhesive members 30 on only one end and welding them may also be used. In that case, the adhesive member 30 may be arranged on either one of the end faces of the opposing frames.
