Furthermore, the upper and lower frames 31, 32 and the end frame 33 of the outer shoji 3 are similar to the upper and lower frames 21, 22 and the end frame 24 of the inner shoji 2, so their explanation will be omitted here.

(Structure of the lower cover member)
In this embodiment, the lower frame 12 of the sash has a metallic lower cover member 126 placed on the upper surface of the outside of the inner screen 2 in the area where the inner screen 2 is located when closed, thereby protecting the insulating bridge 123, which is made of an insulating material such as synthetic resin, from ultraviolet rays and the like, and suppressing deterioration of the sash frame over time.
Below, the lower cover members 125, 126 arranged on the upper surface of the lower frame 12 will be described in further detail.

The lower frame 12 to which the lower cover members 125, 126 are attached has a locking groove 121b on the lower exterior portion of the inner lower rail 121a of the interior shape member 121, and has a locking protrusion 122b on the interior side of the outer lower rail 122a of the exterior shape member 122, as shown in FIG. 4.

As shown in FIG. 4(a), the resin lower cover member 125 has a projection wall 125a that covers the upper surface of the lower frame 12 between the inner lower rail 121a and the outer lower rail 122a, a locking claw 125b provided at the indoor end of the projection wall 125a, a locking portion 125c provided at the outdoor end of the projection wall 125a, and a leg portion 125d protruding from the underside of the projection wall 125a.

The resin bottom cover member 125 is attached to the bottom frame 12 by abutting the legs 125d against the top surface of the exterior profile 122, engaging the locking portion 125c at the exterior end with the locking projection 122b of the bottom frame 12 from below, and engaging the locking claw 125b at the interior end with the locking groove 121b of the bottom frame 12.

When attaching the resin lower cover member 125 to the lower frame 12, as shown in FIG. 5(a), the locking portion 125c on the exterior side of the lower cover member 125 is locked under the locking projection 122b provided on the interior side of the exterior lower rail 122a, and the interior side rotates around the locking portion 125c so that it approaches the lower frame 12.

By rotating the lower cover member 125, as shown in FIG. 5(b), the locking claws 125b on the indoor side of the lower cover member 125 come into contact with the indoor side of the inner lower rail 121a.
Further rotation causes the lower cover member 125 to deform due to its elasticity, but when the locking claws 125b of the lower cover member 125 reach the locking grooves 121b formed on the outside of the inner lower rail 121a, the lower cover member 125 returns to its original shape, and the locking claws 125b lock into the locking grooves 121b, allowing the lower cover member 125 to be attached to the lower frame 12.

As shown in Figures 3 and 4(b), the metal lower cover member 126 has a projection wall 126a that covers the upper surface of the lower frame 12 between the inner lower rail 121a and the outer lower rail 122a, an attachment groove portion 126b provided on the lower surface of the indoor side of the projection wall 126a, a locking portion 126c provided on the outdoor end of the projection wall 126a, and legs 126d and 126e protruding from the lower surface of the projection wall 126a. An elastic member 127 with insulating properties is provided on the indoor side of the projection wall 126a.

The elastic member 127 has an attachment portion 127a and an elastic fin piece 127b that protrudes from one side of the attachment portion 127a. The attachment portion 127a is attached by fitting into an attachment groove portion 126b provided on the underside of the interior side of the metallic lower cover member 126, and the elastic fin piece 127b is provided so as to protrude on the interior side of the lower cover member 126.

The metallic lower cover member 126 is attached to the lower frame 12 by placing the legs 126d, 126e on the upper surface of the exterior profile 122, and with the locking portion 126c at the exterior end locked to the locking projection 122b of the lower frame 12 from below, the elastic member 127 abuts against the exterior surface of the inner lower rail 121a to bias the lower cover member 126 outwards.

The metal lower cover member 126 has a drainage section 126f formed at the exterior end of the projection wall 126a (locking section 126c), and when it is attached between the inner lower rail 121a and the outer lower rail 122a of the lower frame 12, a drainage path can be formed between the outer lower rail 122a to drain water that has accumulated on the upper surface of the lower cover member 126.

When attaching the metal lower cover member 126 to the lower frame 12, as shown in Figures 6(a) and (b), tilt the lower cover member 126 so that the inside side is at the bottom and the outside side is at the top in the expected direction, and bring the inside edge closer to the inner lower rail 121a so that it fits under the bottom frame 22 of the inner screen 2 from the outside side of the sash.

By slipping the interior side of the lower cover member 126 under the bottom frame 22 of the inner screen 2 and bringing it closer to the interior lower rail 121a, the elastic fin piece 127b of the elastic member 127 provided on the interior side of the lower cover member 126 reaches the exterior side of the interior lower rail 121a, but by deforming the elastic fin piece 127b by elasticity, the locking part 126c on the exterior side of the lower cover member 126 can be brought even closer to the interior side of the locking protrusion 122b of the exterior lower rail 122a.

After that, as shown in Figures 7(a) and (b), when the locking portion 126c at the exterior end of the lower cover member 126 reaches the interior side of the locking projection 122b provided on the interior side of the outer lower rail 122a, the locking portion 126c of the lower cover member 126 is moved to a position below the locking projection 122b in a buckling manner, and the locking portion 126c is locked to the locking projection 122b of the lower frame 12.

The lower cover member 126 is biased toward the outside of the room by an elastic member 127 with its outside-side engaging portion 126c engaged beneath the engaging protrusion 122b provided on the indoor side of the outer lower rail 122a. Therefore, the lower cover member 126 can be attached without rattling to the upper surface of the lower frame 12 without shifting toward the outside of the room and coming loose from the engagement with the engaging protrusion 122b.
The metallic lower cover member 126 may be configured such that, when attached, the elastic member 127 protruding toward the indoor side engages with the engaging groove 121b on the outdoor side of the inner lower rail 121a.

(Effects of the sash of this embodiment)
As described above, in the sash of this embodiment, a plastic lower cover member 125 is arranged between the inner lower rail 121a and the outer lower rail 122a of the lower frame 12 on the indoor side of the outer screen 3 when the inner and outer screens 2, 3 are closed, and a metal lower cover member 126 is arranged on the outdoor side of the inner screen 2.

The resin lower cover member 125 arranged on the lower frame 12 covers the upper surface of the exterior shape member 122 that is exposed to the indoor space when the inner and outer screens 2, 3 are closed, thereby preventing cold and heat from being transferred to the indoor space from the upper surface of the exterior shape member 122 that is exposed to the outside air, improving insulation.

The metal lower cover member 126 arranged on the lower frame 12 covers the insulating bridge 123 that connects the interior shape member 121 and the exterior shape member 122 that are exposed to the outdoors when the interior and exterior screens 2, 3 are closed. This protects the insulating bridge 123 from exposure to the outside air, including ultraviolet rays, improves weather resistance, and suppresses damage to the sash due to deterioration over time.

In addition, the metallic lower cover member 126 has an elastic member 127 with insulating properties on the indoor side, so the elastic force of the elastic member 127 stabilizes the installation state of the lower cover member 126, while the insulating properties suppress the transfer of cold and heat from the outdoor exterior shape member 122 to the indoor interior shape member 121, thereby maintaining the insulating properties of the composite sash.

In addition, the resin lower cover member 125 and the metal lower cover member 126 attached to the lower frame 12 can both be removed after the inner and outer screens 2, 3 are fitted, making them easy to install and easy to clean, and therefore easy to maintain.

Needless to say, the above embodiments do not limit the invention described in the claims, but are treated as examples.
