  By the way, there is known a frame body in which the surface of the base material of the frame body (shoji) is covered with a surface member of a color different from that of the base material for the purpose of improving the appearance. When such frames are welded and joined, as shown in Patent Document 1, the frames are butted together and press-bonded by thermal welding to be connected. At this time, at the time of thermal welding, the inner base material and the surface layer member rise from the joint surface between the frames, and burrs are generated on the surface of the frame. When the burrs are removed, the base material is exposed between the frames. Since the color of the base material is different from the color of the surface member, it is necessary to paint the exposed base material in the same color as the surface member. Since the coating of the exposed portion is performed manually, man-hours and material costs are required, and the production efficiency is reduced.

As shown in FIG. 8, the bonding member 30A before welding includes a first bonding portion 31A, a protruding portion 32A extending in a direction orthogonal to the first bonding portion 31A, and a first piece 33 and a second piece 34. ing. As shown in FIG. 9, the first piece 33 and the second piece 34 extend in the extending direction of the protruding portion 32A and project in the direction orthogonal to the extending direction of the first bonding portion 31A and the protruding portion 32A. It is a plate-like member to be formed. The first piece 33 and the second piece 34 are provided at intervals along the extending direction of the first bonding portion 31.
Further, the bonding member 30A is provided with a protrusion 35 that protrudes in a direction orthogonal to the extending direction of the first bonding portion 31A and the protrusion 32A. The protrusion 35 extends above the first bonding portion 31A along the extending direction of the first bonding portion 31A. The protrusion 35 is provided at an interval from the first piece 33 and the second piece 34. Thereby, a depression 36 is formed between the protrusion 35 and the first piece 33 and the second piece 34. The recess 36 can abut (place) on the step 17 formed in the vertical frame 13 on the door end side.

Further, as shown in FIG. 7, a hollow portion S2 is formed inside each frame. Assuming that the dimension of the hollow portion S2 in the indoor / outdoor direction is L1, and the dimension of the extending direction of the first piece 33 and the second piece 34 is L2 as shown in FIG. 9, the dimension L1 of the hollow portion and the first piece 33 The dimension L2 of the second piece 34 is substantially the same as or slightly larger than the dimension L2 of the first piece 33 and the second piece 34. Thereby, the first piece 33 and the second piece 34 are configured to be fitted to the hollow portion S2.
Further, as shown in FIG. 7, when the size of the notch 13e in the indoor / outdoor direction is L3, and as shown in FIG. 9, the size in the extending direction of the protrusion 32A is L4, the size L4 of the protrusion 32A is It is formed smaller. Thereby, when the bonding member 30A is welded, the bonding member 30A is configured to be buried in the notch 13e.

As shown in FIG. 10, the above-described adhesive member 30 </ b> A is arranged at the end 13 a of the door-side vertical frame 13 (adhesive member arrangement step). At this time, the depression 36 of the adhesive member 30A comes into contact with the step portion 17, and the protrusion 32A of the adhesive member 30A is arranged in the cutout 13e of the doorside vertical frame 13.
As shown in FIGS. 10 and 13, in the adhesive member 30 </ b> A, the thickness L <b> 6 of the second adhesive portion 38 of the adhesive member 30 </ b> A is smaller than the thickness L <b> 5 of the doorside vertical frame 13 and the upper frame 15. It is formed thicker. In addition, as shown in FIG. 11, the first piece 33 and the second piece 34 enter the hollow portion S2, and the adhesive member 30A and the door-side vertical frame 13 fit together.

  Similarly to the end 13a of the door-side vertical frame 13, the end 13b of the door-side vertical frame 13, both ends 15a and 15b of the upper frame 15, both ends 16a and 16b of the lower frame 16, and the door-side vertical frame. After arranging the adhesive members 30 on both ends 13a, 13b of the frame 13 and on both ends 14a, 14b of the hanging side vertical frame 14, as shown in FIG. , The both ends 13a, 13b of the door-side vertical frame 13 and the both ends 14a, 14b of the hanging-side vertical frame 14, respectively. A heated hot plate (not shown) is sandwiched between the adjacent adhesive members 30A, and the adhesive member 30A and the end surfaces of the upper frame 15, the lower frame 16, the door-side vertical frame 13, and the suspension vertical frame 14 are melted ( Heating step). Thereafter, as shown in FIG. 13, the end 13a of the door-side vertical frame 13 and the end 15a of the upper frame 15 are pressed against each other. The other ends are similarly butted and crimped, and the upper frame 15, the lower frame 16, the door-side vertical frame 13, and the hanging-side vertical frame 14 are welded and connected (connecting step). At this time, as shown in FIG. 14, the adhesive member 30 protrudes from the surface 20a of the surface member 20, and burrs 37 are generated. The burr 37 is removed using a cutter device or the like so that the adhesive member 30 is substantially flush with the surface 20a of the surface member 20, and the frames are connected with the adhesive member 30 interposed.

  In the shoji 10 of the present embodiment, four corners, ie, between the adjacent upper frame 15 and the door-side vertical frame 13, between the door-side vertical frame 13 and the lower frame 16, and between the lower frame 16 and the hanging base. The upper frame 15, the lower frame 16, the door-side vertical frame 13, and the vertical frame on the hanging side with the adhesive member 30 interposed between the vertical frame 14 on the side and the vertical frame 14 on the hanging side and the upper frame 15. The frames 14 are connected to each other. This can prevent the white frame 11 from being exposed from the surface 20 a of the surface member 20. That is, since the adhesive member 30 is exposed between the upper frame 15, the lower frame 16, the door-side vertical frame 13, and the hanging-side vertical frame 14, the exposed white portion of the frame body 11 is formed on the surface layer as in the related art. It is not necessary to apply the same black color as the member 20. Accordingly, the production efficiency can be improved, and furthermore, the occurrence of color unevenness and the variation in color of each frame can be suppressed, so that the quality can be improved.

In addition, in the present embodiment, since the projections 32 extend in the indoor and outdoor directions, the cutouts 13e formed so that burrs do not appear at corners can be filled.
In the bonding member 30A, the thickness L6 of the second bonding portion 38 of the bonding member 30A is formed thicker than the thickness L5 of the plate thickness of the base material 13A. As shown in FIG. 14, it goes around the lower surfaces of the base materials 13A to 16A. As a result, the bonding area between the adjacent frames is increased, so that the adhesive strength is increased, and the frames are strongly connected to each other.

  In the present embodiment, since the adhesive member 30 is placed on the upper surface 17a of the step 17, the exposure of the frame 11 from the surface 20a of the surface member 20 can be more effectively suppressed.

  Further, in the present embodiment, since the adhesive member 30 is arranged in the notch 13e, the exposure of the white frame 11 can be suppressed even on the side surface 10b of the shoji. Therefore, the trouble of coloring the exposed portion can be omitted. Further, since the adhesive member 30 can be prevented from protruding from the corners of the shoji, the material cost can be reduced.

In the manufacturing method of the shoji 10 according to the present embodiment, both ends 15 a and 15 b of the adjacent upper frame 15, both ends 16 a and 16 b of the lower frame 16, both ends 13 a and 13 b of the door-side vertical frame 13, and the hanging side vertical When the adhesive members 30 arranged on both ends 14a and 14b of the frame 14 are heated and the frames are crimped and connected to each other, the upper frame 15, the lower frame 16, the door-side vertical frame 13, and the hanging-side vertical frame 14 are connected. The adhesive member 30 protrudes from the adhesive. Since the adhesive members 30 of the same color as the surface member 20 are arranged at both ends of the frame, even if the protruding portions (burrs) are cut off, the adhesive members 30 of the same color as the surface member 20 remain. Not exposed. As a result, the cost and labor for painting the white portion exposed between the frames as in the related art can be reduced, and the production efficiency can be improved.
In addition, both ends 15a and 15b of the adjacent upper frame 15, both ends 16 a and 16 b of the lower frame 16, both ends 13 a and 13 b of the door-side vertical frame 13, and both ends 14 a and 14 b of the hanging-side vertical frame 14. Since the adhesive members 30 are disposed on the respective frames, 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 disposed on the upper surface 17a of the step portion 17 by bringing the recess 36 into contact with the step portion 17. Thereby, the exposure of the frame 11 from the surface 20a of the surface member 20 can be reliably suppressed. Further, by making the recess 36 abut on the step 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.

  The embodiments of the frame and the method of manufacturing the frame according to the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the gist of the present invention. Additions, omissions, substitutions, and other modifications of the configuration are possible without departing from the spirit of the present invention. The invention is not limited by the foregoing description, but is limited only by the scope of the appended claims.

For example, in the embodiment, the sash 10 has been described as an example of the frame of the present invention. However, the configuration and the manufacturing method can be similarly applied to the open frame 40. 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. An upper frame 41, a lower frame 42, and a pair of vertical frames 43 in a state where an adhesive member is interposed between the end 44a of the vertical frame 44 and the end 44a of the vertical frame 44 and the end 41b of the upper frame 41. , 44 may be connected.
In addition, the surface member 20 is configured to cover the surface 11a and the side surface 11b of the frame 11, but it is sufficient that the surface member 20 covers at least the surface 11a of the frame 11.
Although the surface member 20 is configured to be provided on the outdoor surface 11a of the frame 11, the surface member 20 may be provided on the indoor surface of the frame 11, and both the indoor and outdoor surfaces may be provided. May be provided with a surface member 20.

The adhesive member 30 has the first adhesive portion 31 and the second adhesive portion 38, but the adhesive member 30 is interposed between adjacent frames at least on the surface of the frame 11 including the surface member 20. In this state, the frames need only be connected to each other, so that the second bonding portion 38 need not be provided. Further, the first piece 33 and the second piece 34 are not necessarily provided, and may be one of them.
Further, a configuration in which no step is provided in each frame may be employed. Even if each frame does not have a step, by providing an adhesive member between the frames, the frame 11 can be prevented from being exposed from the surface 10a of the shoji.
Notch 13e does not necessarily have to be formed.

  In this embodiment, the method of arranging and welding the adhesive members 30 at both ends of each frame has been described. However, the method of arranging and welding the adhesive members 30 only at one end may be used. In that case, the adhesive member 30 may be arranged on one of the end faces of the facing frame.
