  In the conventional composite sash, the resin material constituting the composite material of the shoji is formed to have a hollow cross section in order to enhance heat insulation. However, the composite sash not only improves the heat insulation, but can also improve the design of the indoor side, so it is necessary to use the composite sash for design even in areas that do not require much heat insulation. is there. In this case, if the shoji is formed of a resin material having a hollow cross-section, the heat insulating performance is excessive and the sash is expensive. Therefore, by making the resin material into a plate shape, a low-cost sash can be achieved while ensuring the interior design.

  However, the strength of the resin material is insufficient simply by making the resin material into a plate shape. The shoji resin material constitutes the interior surface of the housing, and there are a portion covering the interior surface of the metal material and a portion consisting only of the resin material, and it is particularly necessary to ensure the strength at the joint between the metal material and the resin material.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a composite sash shoji made of a composite material and having a high strength casing.

In order to solve the above problems, the sash shoji of the composite sash according to the present invention is housed in a frame body provided in a building opening, and is composed of a top and bottom reed and a left and right reed combined in a square shape. In a composite sash shoji composed of a glass body inside the body, and the reed and vertical reed are composed of a metal reed on the outdoor side and a resin reed covering the indoor exposed surface of the metal reed,
The reed has a glass opening groove for housing the glass body on the inner peripheral surface side, and has a rail groove straddling the rail formed on the frame body on the outer peripheral side surface,

As shown in this figure, an engagement portion 41a is formed at the inner peripheral side end of the metal lower collar 41, and an engagement portion 41a is formed at the root of the glass groove constituting portion 42a of the resin lower collar 42. An engaged portion 42c is formed to engage with. A hollow portion 42d is further formed in the resin lower collar 42 adjacent to the outdoor side of the engaged portion 42a. Since the base portion of the glass groove constituting portion 42a has the engaged portion 42c, the strength is required. By forming the hollow portion 42d here, sufficient strength can be ensured. . In addition, you may form as a thick part which does not have a cavity instead of the hollow part 42d formed in a hollow shape with a cavity. In any case, the strength in the vicinity of the engaged portion 42c, which is a fixed portion, can be increased.

  Further, the glass groove constituting portion 42a of the resin lower collar 42 is formed in a plate shape, and is thicker than the rail groove constituting portion 42b that is also formed in a plate shape. Since the rail groove constituting portion 42b is superposed with respect to the metal lower collar 41 constituting the outdoor surface of the rail groove 46, the strength is not required so much. On the other hand, the glass groove constituting part 42 a is configured to form the interior surface of the glass opening groove 45 only with a resin material, and therefore needs strength to sandwich the glass body 3 via the Grechan 7. By making the glass groove constituting part 42a thicker than the rail groove constituting part 42b, the strength can be sufficiently secured.

  The rail groove constituting part 42b of the resin lower collar 42 is substantially polymerized on the interior surface of the metal lower collar 41 in the resin lower collar 42 of the outer shroud 4 and substantially lower in the resin lower collar 42 of the inner shroud 5.

Further, on the outer peripheral surface side of the upper collar 50, a groove-like rail groove 56 is formed which is concave so as to straddle the outer rail 21a or the inner rail 21b over substantially the entire length in the longitudinal direction.

  The metal upper collar 51 constitutes the outdoor surface of the glass opening groove 55 and the outdoor and indoor surfaces of the rail groove 56. Further, the resin upper flange 52 is composed of a glass groove constituting portion 52a constituting the indoor surface of the glass opening groove 55 and a rail groove constituting portion 52b covering the indoor surface of the rail groove 56 of the metal upper flange 51 in a superposed manner. Yes. That is, as in the case of the lower rod 40, the outdoor surface of the glass opening groove 55 is composed of the metal upper collar 51 and the indoor surface is composed of the resin upper collar 52. Therefore, the glass body 3 accommodated therein has the outdoor surface facing the metal upper collar 51. Thus, the indoor surface is supported by the resin upper collar 52, respectively.

  FIG. 4 shows an enlarged view of the vicinity of the upper arm 50 of the shoji screen. As shown in this figure, in the upper collar 50, similarly to the lower collar 40, an engagement portion 51 a is formed at the inner peripheral side end of the metal upper collar 51, and the glass groove constituting portion of the resin upper collar 52. An engaged portion 52c that engages with the engaging portion 51a is formed at the root portion of 52a. The resin upper collar 52 is further formed with a hollow portion 52d adjacent to the outdoor side of the engaged portion 52c. Thereby, the intensity | strength of resin upper collar 52 is fully securable. In addition, you may form as a thick part which does not have a cavity instead of the hollow part 52d formed in a hollow shape. In any case, the strength in the vicinity of the engaged portion 52c, which is a fixed portion, can be increased.

  Further, the glass groove constituting portion 52a of the resin upper collar 52 has a plate shape and is thicker than the rail groove constituting portion 52b which is also formed in a plate shape. Thereby, the glass body 3 can be firmly clamped by the glass opening groove 55.

  As for the rail groove structure part 52b of the resin upper collar 52, both the resin upper collar 52 of the external shoji 4 and the resin upper collar 52 of the inner shroud 5 almost entirely cover the interior surface of the metal upper collar 51 in a polymerized manner. The end portion of the resin upper collar 52 is engaged with and fixed to the inner peripheral end portion of the metal upper collar 51.

  The downpipe 60 is comprised from the metal downpipe 61 and the plate-shaped resin downpipe 62 attached to the indoor surface. A concave and groove-shaped glass opening groove 65 is formed on the inner peripheral surface of the metal vertical rod 61 so that the glass body 3 can be accommodated with the Grechan 7 held therebetween. Also in the vertical gutter 60, the outdoor surface of the glass body 3 is supported by the metal vertical gutter 61, and the indoor surface is supported by the resin vertical gutter 62, respectively.
