The first feature of the present embodiment is that resin frames 60 to 62 are attached to the interior side surfaces of the frame 10, the door body frame 20, and the metal frame 40 of the shoji frame A. In other words, the skeleton frame 10, the door body frame 20, and the shoji frame A are composed of a combination of the metal frame 40 and the resin frames 60 to 62. First, as shown in FIGS. 1, 3, and 4, a resin frame 60 attached to the frame 10 has mounting portions 19a and 19b.
Are formed to be three-dimensionally thick as a whole. Since the resin frame 60 is located around the indoor side of the door body frame 20, it also serves as a decorative frame, and a material, a shape and a color excellent in design are selected.

Next, as shown in FIGS. 1, 3, and 4, the resin frame 61 attached to the door body frame 20 has a flat portion 61b on the indoor side and an attaching portion 61a to be attached to the attaching portions 29a and 29b. It is formed into a thin, plate-like shape as a whole. The resin frame 62 attached to the metal frame 40 is formed with a flat portion 62b on the indoor side and attachment portions 62a to be attached to the attachment portions 49a, 49b. The resin frame 62 has, as a separate body, a pressing edge 62c for holding the shoji board 31 at its peripheral portion.

Releases the above two engaging / locking parts so that the shoji frame A
It can be easily removed from. Also, the pressing edge 62
Since the tongue piece 62g is formed near the bent portion of the metal frame 40c even when the pressing edge 62c does not hold the shoji 31.
And the synthetic resin frame 62 are engaged and held, so that there is no need for the operator to support the pressing edge 62c when attaching or detaching the shoji.

The interior side surfaces of the extended portion 62d of the pressing edge 62c, the resin frame 62, and the resin frame 60 for the door body frame 20 are substantially flush with each other. The end of the extension 62d is formed as a protruding piece 62e, and is in contact with the shoji board 31 via the soft tongue piece 62f. With the above configuration, the hot air or cold air transmitted from the metal frame 40 located on the outdoor side is not transmitted to the room because it is insulated by the resin frame 60 on the indoor side. In addition, the indoor side is combined with the resin frames 60 to 62 together with the ridge 6.
Since 2c is also made of synthetic resin, various design effects can be expected by selecting the material, shape, and color of the resin frame. A pressing edge 62 formed by the metal frame 40 and the synthetic resin frame 62 is used.
As for the support of c, means can be appropriately combined depending on its position.

2a is located outside the projecting portion 60b and the flat portions 61b and 62b, and the mounting is ensured by using a combination of two mounting means, ie, a caulking means and a press-fitting engagement means. The total dimension (width dimension) with the frame can be reduced, and the appearance is good in appearance.

In particular, the metal frame 40 and the resin frame 62 are formed with mutual mounting portions 49a and 49b at locations spaced apart in the width direction of the shoji frame A, one of which is a caulking portion 49a, and the other is a caulking portion 49a. Of the metal frame 40
Even if a slight length or other distortion occurs between the two frames due to the difference in the coefficient of thermal expansion due to the difference in the material of the resin frame 62 and the resin frame 62, the engagement portion 49b
Therefore, distortion such as warping or bending of the shoji frame A is small. In addition, the shoji frame A can be designed precisely because the possibility of occurrence of distortion is small, and confidentiality and heat insulation can be improved.

Furthermore, the resin frame 62 is easily and reliably attached to the metal frame 40, and the total size (expected size) in the indoor and outdoor width directions is reduced as much as the size of the mounting portion can be simplified and reduced in size. As a result, the weight of the shoji can be reduced as a whole, and the manufacturing cost can be reduced.

Further, the shoji board is held on the shoji frame A via the ridge 62c, and the ridge 62c is detachably engaged with and held by the metal frame 40 and the resin frame 62.
Since the soft tongue piece 62f is attached to the shoji board holding portion of c,
The elasticity of the resin frame 62 and the adhesion of the soft tongue piece 62f to the shoji board holding surface ensure the holding of the shoji board 31, improve the airtightness, and improve the heat insulating function. Further, since the pressing edge 62c is made of a synthetic resin and made of the same kind of material as the synthetic resin frame 62, an effect in design can be expected. Note that the engaging portion 49b in the above embodiment includes "hook, fit, press" and the like, and the metal frame 40 and the resin frame 62 can slightly move (shift) or elastically deform. It is assumed to be a configuration.

According to the present invention, the following effects can be obtained by the above configuration. 1. According to the first aspect of the present invention, since the outdoor frame and the resin frame on the indoor side that constitute the shoji frame A are configured, the heat from the metal frame is insulated by the resin frame, and the indoor and outdoor hot air and Cold air is not transmitted outside through the metal frame. Since the metal frame and the resin frame have mutual mounting portions formed at locations spaced apart in the width direction of the shoji frame A, one of the mounting portions is a caulking portion, and the other is an engaging portion, Due to the difference in the coefficient of thermal expansion due to the difference in the material of the metal frame and the resin frame, even if a slight length or other distortion occurs between the two frames, the distortion can be absorbed by the engaging portion. -Less distortion such as bending. In addition, the shoji frame A can be designed precisely because the possibility of occurrence of distortion is small, and confidentiality and heat insulation can be improved.

Further, the total size (expected size) in the width direction of the room can be reduced as much as the mounting of the resin frame to the metal frame is easy and reliable, and the structure of the mounting portion can be simplified and downsized. As a result, the weight of the shoji can be reduced as a whole, and the manufacturing cost can be reduced. Further, since the ridge is made of a synthetic resin and the same kind of material as the synthetic resin frame, the material of the indoor side surface is unified as a shoji frame, and an effect on design can be expected.

2. According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the ridge is formed to have a substantially L-shaped cross section, and a tongue piece is formed near the bent portion of the ridge. Since one end of the ridge is engaged with the engaging portion provided on the metal frame and the bent portion is locked to the end of the synthetic resin frame, the mounting structure of the ridge is simplified and The attachment and detachment of the ridge becomes easy.

Further, since the tongue is formed near the bent portion of the ridge, the ridge is engaged with and held by the metal frame and the synthetic resin frame even when the sash is not held. In addition, the operator does not need to support the ridge when attaching or detaching the shoji.
