Other configurations of the upper frame and the door frame of the outer sash are almost the same as those of the inner sash 2, and thus description thereof will be omitted.

(Upper resin cover member)
The configuration of the upper frame portion of the sash according to the present embodiment will be described in more detail.
In the sash according to the present embodiment, as shown in FIG. 4, of the inner peripheral recess 11 f of the upper frame 11 for guiding the inner sash 2, the inner side portion of the outer sash 3 when the inner and outer sashes 2 and 3 are closed. , An upper resin cover 51 is provided.

  The upper resin cover 51 includes a resin cover main body 511 attached to the inner peripheral concave portion 11f of the upper frame 11, and a flap member 512 that is swingably supported by the resin cover main body 511.

  The resin cover main body 511 includes an upper wall portion 511a that covers an inner peripheral surface (an upper surface of the inner peripheral concave portion 11f) of the upper frame main body portion 11a that forms the inner peripheral concave portion 11f of the upper frame 11, and a chamber that forms the inner peripheral concave portion 11f. An indoor side wall portion 511b that covers the outdoor side surface of the inner finding wall portion 11b (the indoor side surface of the inner peripheral concave portion 11f) and an indoor side surface of the central finding wall portion 11c that forms the inner peripheral concave portion 11f (the outdoor side of the inner peripheral concave portion f). ) To cover the outside wall portion 511c.

  The indoor side wall portion 511b has, at a lower end, an engaging portion that can be placed and engaged with the airtight material holding portion of the indoor side finding wall portion 11b, and the indoor side made of a soft synthetic resin material near the engaging portion. The flap portion 511d extends toward the outdoor side. Note that the resin cover main body 511 is preferably formed of a hard synthetic resin material at portions other than the indoor side flap portion 511d.

  The outdoor side wall portion 511c includes a first hollow portion 511e that covers the indoor side surface of the central finding wall portion 11c, and a second hollow portion that extends from the lower end of the first hollow portion 511e to the outside and covers the lower surface of the central finding wall portion 11c. 511f and a third hollow portion 511g extending from the lower end of the first hollow portion 511e to the inside of the room, forming an inverted T-shape as a whole.

An engagement portion 511h is provided below the first hollow portion 511e and above the second hollow portion 511f to engage with an engagement claw formed at the lower end of the central finding wall portion 11c.
Further, a flap supporting portion 511i for swingably supporting the flap member 512 is formed below the first hollow portion 511e on the upper surface of the third hollow portion 511g.

  On the lower surface of the outdoor side wall portion 511c, that is, on the lower surfaces of the second hollow portion 511f and the third hollow portion 511g, two fin pieces arranged in the expected direction are formed downward, and the two fin pieces are When the outer sash 3 is closed, the upper sash 31 of the outer sash 3 is close to the upper resin frame 312.

  The flap member 512 includes a support leg 512b formed on the lower exterior side, a finding wall 512c rising from the indoor end of the support leg 512b, and a projection wall extending from the upper end of the discovery wall 512c to the interior. 512a.

  The flap member 512 has the outdoor end of the support leg portion 512b swingably supported by a flap support portion 511i formed below the outdoor wall portion 511c of the resin cover body 511. Since the lower surface of the inner wall 512b is placed on the upper surface of the third hollow portion 511g of the outer wall portion 511c, the finding wall portion 512c is maintained in a vertical state at a predetermined interval with respect to the outer wall portion 511c. At the same time, the prospect wall portion 512a is maintained in a horizontal state at a predetermined interval from the upper wall portion 511a.

  Furthermore, the bottom wall portion of the upper resin cover 51 is formed by the indoor side end of the projection wall portion 512a of the flap member 512 approaching the indoor side flap portion 511d of the resin cover main body 511. The cover main body 511 and the flap member 512 form a heat insulating space S1 continuous on the outdoor side and the upper side.

  When arranging the upper resin cover 51 on the upper frame 11, the upper resin cover 51 is inserted into the inner peripheral recess 11 f of the upper frame 11 from below, so that the elasticity of the resin cover main body 511 causes the upper resin cover 51 to move. 51 is deformed and passes between the airtight material holding portion of the indoor side finding wall portion 11b and the engaging claw formed at the lower end of the central finding wall portion 11c, and thereafter, the engagement of the indoor side wall portion 511b The upper portion is engaged with the airtight material holding portion of the indoor side finding wall portion 11b and the engaging portion 511h of the first hollow portion is engaged with the engaging claw of the center finding wall portion 11c. 51 can be attached.

  The upper resin cover 51 attached to the inner peripheral concave portion 11f is arranged so that the metal portion is not exposed on the inner peripheral surface of the inner peripheral concave portion 11f, and is relatively large continuous to the upper portion of the inner peripheral concave portion 11f and the outdoor portion. Since the heat insulating space S1 is formed, the heat insulating performance of the upper frame 11 on the indoor side of the outer sash 10 when the sash is closed can be improved.

  When the inner sash 2 is erected, as shown in FIG. 5, the upper end of the inner sash 2 abuts on the flap member 512 so that the flap member 512 rotates about the support leg 512b. 51 is made of a hard synthetic resin material to form a relatively large heat-insulating space, while enabling the inner shoji 2 to be easily installed.

As described above, in the sash of the present embodiment, the upper resin cover 51 having a large heat insulating space at the indoor side portion of the outer sash 3 of the upper frame 11 exposed to the room when the inner and outer sashes 2 and 3 are closed. Is arranged, so that the heat insulation performance can be improved.
In addition, since all or most of the upper resin cover 51 can be formed of a hard synthetic resin material, it is possible to suppress performance degradation due to deterioration over time.

  Further, since the flap member 512 is supported below the resin cover main body 511, the resin cover main body 511 is slightly deformed due to a manufacturing error or the like when the upper resin cover 51 is disposed in the inner peripheral recess 11f. Even in this case, the support of the flap member 512 is hardly affected, so that the flap member 512 can be maintained in an appropriate state, and a wide heat insulating space can be reliably maintained.

  In addition, by forming the bottom wall of the upper resin cover 51 with two members, the flap member 512 on the outdoor side and the flap portion 511d on the indoor side, the allowable swing angle of the flap member 512 is increased. This enables the smooth installation of the inner sash 2. Furthermore, by forming the indoor side flap portion 511d of the upper resin cover 51 with a soft synthetic resin and forming it with a short width in the expected direction, it is easy to form, and the breakage of the inner sash 2 at the time of installation is prevented. At the same time, deformation of the heat insulating space S1 due to settling of the indoor side flap portion 511d or the like can be minimized.

It is needless to say that the above embodiments do not limit the invention described in the claims but are treated as examples.
For example, in the sash of the present embodiment, the bottom wall portion of the upper resin cover 51 is formed by the flap member 512 and the indoor side flap portion 511d, but may be formed only by the flap member 512, The inner flap portion 511d may be in contact with the inner flap portion 511d.
Further, the flap member 512 may be swingably supported at a position below the indoor side wall portion 511b of the upper resin cover 51.
In addition, the sash is not limited to the pulling sash, and may be a sash in which a shoji is killed.
