Therefore, the fitting recess 21a1 has an inner diameter larger than the outer diameter of the head of the screw, and a depth larger than the height of the head of the screw and the protrusion of the fitting protrusion 22a1 of the upper second blocking member 22, so that the head of the screw can be hidden when the fitting protrusion 22a1 of the upper second blocking member 22 is fitted.

[0021] In addition, at the exterior end of the upper first blocking movable shoji side portion 21a, three rows of rubber blocking member side airtight material 21a3 are provided so that when the shoji screen is attached to the joining mullion 16d, they are continuous with the rubber mullion side airtight material 16d3 (see Figure 2) of the joining mullion 16d.

[0022] Furthermore, on the inner surface side of the upper first blocking movable screen side portion 21a, a cylindrically protruding screw hole fitting protrusion 21a4 is provided above the screw through hole 21a2 so as to fit into the screw through hole (coaxial with the tapping hole of the upper attachment 16a1) provided in the metal member 16d1 of the joint mullion 16d for positioning, etc., and an engagement piece 21a5 is provided which has a claw portion 21a51 which engages with the metal member 16d1 of the joint mullion 16d (see Figure 8) and temporarily fastens the upper first blocking member 21 to the joint mullion 16d, etc. The engagement piece 21a5 is provided inclined toward the outside of the room, i.e., the blocking member side airtight material 21a3 side, so that the upper first blocking member 21 can be temporarily fastened to the joint mullion 16d by elastic force even before the screw is passed through the screw through hole 21a2.

[0023] The upper first blocking room side portion 21b has a vertical surface portion 21b1 and an inclined surface portion 21b2 that conforms to the front shape of the upper first blocking movable shoji side portion 21a, and the lower end of the inclined surface portion 21b2 is provided with an engagement recess 21b21 into which the engagement portion 22c1 (described later) of the upper second blocking member 22 is inserted and engages, as shown in Figures 5(a) and (b), etc.

[0024] (Upper second blocking member 22) The upper second blocking member 22 is a separate member from the upper first blocking member 21, and is a resin member that is fitted into the upper first blocking member 21 and installed in the joint mullion 16d as shown in Figures 8 and 9 described below. As shown in Figures 7(a) to (c), it is composed of an upper second blocking movable shoji side portion 22a that is installed on the outside of the upper first blocking movable shoji side portion 21a of the upper first blocking member 21, an upper second blocking room side portion 22b that extends perpendicularly from the indoor end of the upper second blocking movable shoji side portion 22a and is installed to block the lower part of the upper first blocking room side portion 21b of the upper first blocking member 21, and an upper second blocking upper side portion 22c that bends perpendicularly from the upper end of the upper second blocking room side portion 22b to the outdoor side and blocks gaps, etc. between the metal member 16d1 and the resin cover 16d2 of the joint mullion 16d.

[0025] The upper second blocking movable shoji side portion 22a has a U-shaped, semicircular, or partially missing circular fitting protrusion 22a1 on the inner surface side facing the upper first blocking movable shoji side portion 21a of the upper first blocking member 21, which fits into the recessed screw-through hole 21a2 of the upper first blocking movable shoji side portion 21a.

[0026] The upper second blocking upper side surface portion 22c is provided with an engagement portion 22c1 which extends further toward the exterior side and engages with an engagement recess 21b21 at the lower end portion of the upper first blocking indoor side surface portion 21b of the upper first blocking member 21.

[0027] <Use state of the mullion closing member 2 of the externally movable single sliding window 1 of embodiment 1> Next, a description will be given of the usage state of the mullion blocking member 2 of the externally movable single sliding window 1 of embodiment 1 configured as above.

[0028] When attaching the upright blocking member 2 of embodiment 1 of the present invention to the upper end of the joint mullion 16d of the external sliding window 1 shown in Figures 1 to 3, first the upper first blocking member 21 that constitutes this upright blocking member 2 is fixed to the upper end of the joint mullion 16d of the external sliding window 1 with screws, and then the second blocking member 22 is fitted into the fixed upper first blocking member 21 and attached as shown in Figures 8 and 9.

[0029] At this time, the upper first blocking member 21 has a cylindrically protruding screw hole fitting convex portion 21a4 provided on the inner surface side of the upper first blocking movable screen side portion 21a fitted into the engaged hole portion 16d11 (see Figure 8) provided in the metal member 16d1 of the joining mullion 16d to perform positioning, etc., and the claw portion 21a51 at the tip of the engagement piece 21a5 engages with the engaged portion 16d12 (see Figure 8, etc.) of the metal member 16d1 of the joining mullion 16d to temporarily fasten the upper first blocking member 21 to the joining mullion 16d, and then a screw (not shown) is inserted through the screw through hole 21a2 of the upper first blocking movable screen side portion 21a to fix it to the upper end of the metal member 16d1 of the joining mullion 16d.

[0030] Therefore, before fixing the upper first blocking member 21 with screws to the upper end of the joining mullion 16d, alignment, etc. can be performed using the screw hole fitting protrusion 21a4 provided on the inner surface of the upper first blocking movable screen side portion 21a, and the upper first blocking member 21 can be temporarily fastened to the joining mullion 16d using the engagement piece 21a5, thereby improving workability when installing the upper first blocking member 21.

[0031] Next, the fitting convex portion 22a1 (see Figure 7, etc.) of the upper second blocking movable screen side portion 22a of the upper second blocking member 22 is fitted into the screw-through hole 21a2 (see Figure 4, etc.) of the upper first blocking member 21 so as to cover the outside of the upper first blocking member 21 attached to the upper end of the joining mullion 16d, and the upper second blocking member 22 is attached to the upper first blocking member 21 by engaging the engagement portion 22c1 with the engagement recess 21b21 at the lower end of the upper first blocking room side portion 21b of the upper first blocking member 21, thereby completing the installation of the mullion blocking member 2 of embodiment 1 consisting of the upper first blocking member 21 and the upper second blocking member 22.

[0032] Furthermore, when performing maintenance work on the joint mullion 16d, such as replacing the plastic cover 16d2 of the joint mullion 16d, which is the inner joint frame, the maintenance work for the joint mullion 16d can be performed by performing the reverse procedure to the installation work of the mullion closing member 2 in the above-described embodiment 1 at the upper end of the joint mullion 16d, i.e., first removing the upper second closing member 22 from the upper first closing member 21, then removing the screws to remove the upper first closing member 21 from the joint mullion 16d, and replacing the plastic cover 16d2 of the joint mullion 16d.

[0033] <Summary of the mullion closing member 2 according to the first embodiment of the present invention> Therefore, the mullion blocking member 2 of embodiment 1 of the present invention is fixed to the joint mullion 16d of the indoor fixed screen 16 fixed to the window frame of the external sliding window 1, and comprises an upper first blocking member 21 made of resin which is provided with an engaging recess 21a1 into which the engaging protrusion 22a1 of the upper second blocking member 22 engages, and an upper second blocking member 22 made of resin which is provided with an engaging protrusion 22a1 which engages with the engaging recess 21a1 of the upper first blocking member 21 and is attached to the upper first blocking member 21 so as to cover the engaging portion 21a1.

[0034] Therefore, the mullion blocking member 2 of embodiment 1 is divided into two members, the upper first blocking member 21 and the upper second blocking member 22, and the upper second blocking member 22 is attached to the upper first blocking member 21 by fitting between the fitting convex portion 22a1 and the fitting recess 21a1.Therefore, it can be easily removed from the joint mullion 16d of the externally movable single-sliding window 1, and maintenance work on the joint mullion 16d, such as replacing the plastic cover 16d2 of the joint mullion 16d of the externally movable single-sliding window 1, can be easily performed.

[0035] In particular, the mating recess 21a1 of the upper first blocking member 21 has an inner diameter larger than the outer diameter of the head of the screw that fixes the upper first blocking member 21 to the fitting mullion 16d, and has a depth larger than the height of the head of the screw and the protrusion amount of the mating protrusion 22a1 of the upper second blocking member 22.Therefore, when the mating protrusion 22a1 of the upper second blocking member 22 is mated, the head of the screw can be hidden, and the design can also be improved.

[0036] In addition, in the upright blocking member 2 of embodiment 1 of the present invention, an engagement recess 21b21 is provided on the upper first blocking room inner side portion 21b of the upper first blocking member 21, as shown in Figures 5(a), (b), etc., while an engagement portion 22c1 that engages with the engagement recess 21b21 is provided on the upper end portion of the upper second blocking room inner side portion 22b of the upper second blocking member 22.

[0037] Therefore, the upper second closing member 22 can be attached to the upper first closing member 21 more reliably.

[0038] In addition, in the mullion closing member 2 of embodiment 1 according to the present invention, the upper first closing member 21 is provided with a claw portion 21a51 of the engagement piece 21a5 that engages with the engaged portion 16d12 (see Figure 8, etc.) of the metal member 16d1 of the joining mullion 16d.

[0039] Therefore, when attaching the upper first blocking member 21 to the joining post 16d, the claw portion 21a51 of the engaging piece 21a5 makes it possible to temporarily fasten the upper first blocking member 21 to the joining post 16d, thereby improving the ease of attachment of the post blocking member 2.

[0040] In addition, in the mullion blocking member 2 of embodiment 1 of the present invention, the upper frame 11 and lower frame 12 of the externally movable single-sliding window 1 are provided with rubber frame side airtight materials 11c, 12c along their respective rails at least near the joint mullion 16d, while the upper first blocking member 21 is provided with a blocking member side airtight material 21a3 that elastically contacts the frame side airtight material 11c of the upper frame 11.

[0041] Therefore, when the mullion blocking member 2 of embodiment 1 is attached to the joint mullion 16d, the upper end of the blocking member side airtight material 21a3 of the upper first blocking member 21 elastically contacts the frame side airtight material 11c at the upper end of the joint mullion 16d, thereby further improving the airtightness and watertightness of the upper end of the joint mullion 16d of the externally movable single-sliding window 1.

[0042] In the above explanation of embodiment 1, an externally movable single-sliding window 1 having an externally movable shoji screen 15 that can be opened and closed on one side of an internally fixed shoji screen 16 as shown in Figure 1 was used as an example. However, the present invention is not limited to this, and may of course also be applied to, for example, an externally movable single-sliding window 1' having an externally movable shoji screen 15' on each side of an internally fixed shoji screen 16' as shown in Figure 10.

[0043] Embodiment 2. Next, a mullion blocking member 2' according to the second embodiment of the present invention will be described. In the explanation of the mullion blocking member 2 of the first embodiment above, as shown in Figures 2 and 3, a mullion blocking member 2 that is attached to a joining mullion 16d that has a small amount of protrusion toward the inside of an externally movable sliding window with a small height dimension is explained as an example. However, in the mullion blocking member 2' of the second embodiment, a mullion blocking member that is attached to a joining mullion 16d' that has a large amount of protrusion toward the inside of an externally movable sliding window with a large height dimension will be explained.

[0044] Figure 11 is a cross-sectional view of an externally movable single-sliding window 1" in which a mullion blocking member 2' for an externally movable single-sliding window according to embodiment 2 of the present invention is installed, and Figure 12 is a longitudinal cross-sectional view thereof. In the externally movable single-sliding window 1" shown in Figures 11 and 12, the same components as those in the externally movable single-sliding window 1 shown in Figures 2 and 3 are given the same symbols and their explanations will be omitted.

[0045] The only difference between the external sliding window 1" shown in Figures 11 and 12 is that the amount by which the joint mullion 16d" protrudes toward the inside of the room is greater than the amount by which the joint mullion 16d of the external sliding window 1 shown in Figures 2 and 3 protrudes toward the inside of the room, and the visible dimension, which is the width of the joint mullion 16d" is the same as that of the joint mullion 16d of the external sliding window 1 shown in Figures 2 and 3.

[0046] Therefore, in the upright blocking member 2' of embodiment 2 of the present invention, the first blocking member is the same as the upper first blocking member 21 of the upright blocking member 2 of embodiment 1 described above, and only the upper second blocking member 22' is different.

[0047] Figures 13(a) to (c) are respectively a plan view, a front view, and a right side view of the upper second blocking member 22' that constitutes the mullion blocking member 2' of embodiment 2 of the present invention, which is attached to the upper end of the joint mullion 16d'' of the external sliding window 1'' shown in Figures 11 and 12.

[0048] The upper second blocking member 22' constituting the mullion blocking member 2' of embodiment 2 shown in Figures 13(a) to (c) is provided at the upper end of the joining mullion 16d" of the externally movable single-sliding window 1" shown in Figures 11 and 12. Therefore, although the apparent dimension, which is the width of the upper second blocking room side portion 22b', is the same, the projected dimension, which is the amount of protrusion toward the room of the metal member 16d1" and the resin cover 16d2" constituting the joining mullion 16d", is large. Therefore, the projected dimension of the upper second blocking movable shoji side portion 22a' is made larger than the upper second blocking movable shoji side portion 22a of the upper second blocking member 22 constituting the mullion blocking member 2 of embodiment 1, and the projected dimension of the upper second blocking upper side portion 22c' is also made larger, and further, a second blocking movable shoji opposite side portion 22d' is provided to face the upper second blocking movable shoji side portion 22a'.

[0049] Furthermore, the upper second blocking movable shoji side portion 22a' is provided with an engaging protrusion 22a1' on the inner surface side facing the upper first blocking movable shoji side portion 21a of the upper first blocking member 21, which engages with the recessed screw-through hole 21a2 of the upper first blocking movable shoji side portion 21a, similar to the engaging protrusion 22a1 of embodiment 1.

[0050] In addition, since the metal member 16d1" and resin cover 16d2" of the joining mullion 16d" protrude toward the indoor side toward the indoor side by a large amount, the upper second blocking upper side surface portion 22c' does not have an engagement portion 22c1 that engages with the engagement recess 21b21 at the lower end of the upper first blocking indoor side surface portion 21b of the upper first blocking member 21, but rather has a pair of engagement portions 22c1', 22c1' on the underside of the upper second blocking upper side surface portion 22c' that are inserted into the gaps between the upper left and right ends of the metal member 16d1" and the resin cover 16d2", and whose tip claw portions 22c11' engage with the engaged hole portions 16d11" (see Figures 14 and 15) formed in the metal member 16d1".

[0051] The upper second blocking member 22' of embodiment 2 configured as described above and the upper first blocking member 21 of embodiment 1 can be used to form the mullion blocking member 2' of embodiment 2 of the present invention.When the mullion blocking member 2' of embodiment 2 configured from these two members is used to attach to the upper end of the joint mullion 16d" of the external sliding window 1" shown in Figures 11 and 12, the mullion blocking member 2' of embodiment 2 of the present invention can be installed as shown in Figures 14 and 15.

[0052] <Summary of the mullion blocking member 2′ of the second embodiment according to the present invention> Therefore, according to the mullion blocking member 2' of embodiment 2 of the present invention, like the mullion blocking member 2 of embodiment 1, it is configured by dividing it into two members, the upper first blocking member 21 and the above-mentioned upper second blocking member 22', so that it can be easily removed from the joint mullion 16d'' of the externally movable single-sliding window 1, like the mullion blocking member 2 of embodiment 1, and maintenance work on the joint mullion 16d'', such as replacing the plastic cover 16d2'' of the joint mullion 16d'' of the externally movable single-sliding window 1'', can be easily performed.

[0053] In particular, in the upright blocking member 2' of embodiment 2, it is possible to use the same upper first blocking member 21 as the upright blocking member 2 of embodiment 1, and only the upper second blocking member 22' needs to be prepared as a different member, thereby reducing manufacturing costs and management costs.

[0054] Furthermore, in the case of the mullion blocking member 2' of embodiment 2, like the mullion blocking member 2 of embodiment 1, it can be applied not only to an externally movable single-sliding window 1 having an externally movable shoji screen 15 on one side of an internally fixed shoji screen 16 as shown in Figure 1, but also to an externally movable single-sliding window 1' having an externally movable shoji screen 15' on each side of an internally fixed shoji screen 16' as shown in Figure 10.

[0055] Embodiment 3. The mullion blocking members 2, 2' in the above embodiments 1 and 2 are described as mullion blocking members that block the upper ends of the joint mullions 16d, 16d' of the externally movable single-sliding window 1, 1' shown in Figures 1 and 10, while the mullion blocking member 3 in the above embodiment 3 is described as a mullion blocking member that blocks the lower ends of the joint mullions 16d, 16d' of the externally movable single-sliding window 1, 1' shown in Figures 1 and 10.

[0056] Figures 16(a) to (c) are respectively a plan view, a front view, and a back view of the lower first blocking member 31 constituting the mullion blocking member 3 of embodiment 3 of the present invention, which is provided at the lower end of the joint mullion 16d, 16d' of the external sliding window 1 shown in Figures 1 to 3 and Figure 10, and Figures 17(a) and (b) are a right side view and a left side view of the lower first blocking member 31 constituting the mullion blocking member 3 of embodiment 3.

[0057] <Configuration of the mullion blocking member 3 of the externally movable single sliding window according to the third embodiment> The mullion blocking member 3 of embodiment 3 is a mullion blocking member that blocks the lower end of the joint mullion 16d, 16d' of the externally movable single-sliding window 1, 1' configured as shown in Figures 1 to 3 and 10, as shown in Figures 19 and 20 described below, and is configured by dividing it into two members, a lower first blocking member 31 and a lower second blocking member 32.

[0058] (Lower first closing member 31) The lower first blocking member 31 is a resin member that is fixed to the lower end of the joint mullion 16d with screws or the like as shown in Figures 19 and 20 described below, and is formed in a shape as shown in Figures 16 and 17.

[0059] In other words, the lower first blocking member 31 mainly has a lower first blocking movable shoji side portion 31a which covers the exterior side of the movable shoji 15 at the lower end of the joining mullion 16d, a lower first blocking indoor side portion 31b which bends perpendicularly from the interior end of the lower first blocking movable shoji side portion 31a and covers the indoor side of the lower end of the joining mullion 16d, and a lower first blocking lower side portion 31c which bends perpendicularly from the lower end of the lower first blocking indoor side portion 31b and covers the lower end of the joining mullion 16d.

[0060] Below the lower first blocking movable shoji side portion 31a, a trapezoidally recessed rail recess 31a1 is provided to avoid the rail 12a1 of the bottom frame 12 of the externally movable single-sliding window 1, and a protrusion 31a2 is provided that protrudes toward the vertical frame 13 side where the ventilation sub-block (not shown) attached to the bottom frame 15b of the outdoor movable shoji 15 abuts, in order to provide a small opening ventilation space between the vertical frame 13 and the vertical frame 15c on the door end side of the outdoor movable shoji 15.

[0061] In addition, the exterior end of the lower first blocking movable shoji side portion 31a is provided with three rows of rubber blocking member side airtight material 31a3 arranged so as to be continuous with the rubber mullion side airtight material 16d3 (see Figure 2) of the lower first blocking movable shoji side portion 31a when attached to the lower first blocking movable shoji side portion 31a, and a positioning protrusion 31a4 is provided on the inside of the lower first blocking movable shoji side portion 31a for passing through the screw hole of the metal member 16d1 of the lower first blocking movable shoji side portion 31a for positioning, etc.

[0062] On the other hand, the lower first blocking room inner side portion 31b is provided with a screw-through hole 31b1 for passing a screw through a screw hole provided at the lower end of the metal member 16d1 of the joining mullion 16d to fix the lower first blocking member 31 to the lower end of the metal member 16d1 of the joining mullion 16d, and is provided with a pair of mating pieces 31b2, 31b2 having mating claws at their tip ends so that a pair of mating pieces 32b, 32b of the lower second blocking member 32 described later can fit into them.

[0063] The lower first blocking lower side portion 31c is provided with a lower second blocking member receiving portion 31c1 which protrudes in the same direction as the pair of fitted pieces 31b2, 31b2 to the same length as the indoor side end of the lower first blocking movable shoji side portion 31a and receives the lower second blocking member 32 together with the indoor side end of the lower first blocking movable shoji side portion 31a. Therefore, when the lower second blocking member 32 is attached to the lower first blocking member 31, the portion where the lower second blocking member receiving portion 31c1 is not provided becomes a working recess 31c2 for inserting the tip of a tool or the like when performing work such as removing the lower second blocking member 32.

[0064] (Lower second blocking member 32) The lower second blocking member 32 is attached so as to face the lower first blocking room interior side portion 31b of the lower first blocking member 31, and is provided with a pair of engaging protrusions 32a, 32a that engage with a pair of mounting holes 16d21, 16d21 (see Figures 19 and 20) formed in the resin cover 16d2 of the joint mullion 16d as shown in Figures 18 to 20, and below the pair of engaging protrusions 32a, 32a, a pair of engaging pieces 32b, 32b that engage with a pair of engaging pieces 31b2, 31b2 (see Figure 17) of the lower first blocking room interior side portion 31b.

[0065] This pair of mating projections 32a, 32a and mating pieces 32b, 32b allows the lower second closing member 32 to be securely attached to the joint mullion 16d and the lower first closing member 31 without using screws or bolts.

[0066] <Use state of the mullion blocking member 3 of the externally movable single sliding window of the third embodiment> Next, the usage state of the mullion blocking member 3 of the externally movable single sliding window of the third embodiment configured as above will be described.

[0067] When attaching the upright blocking member 3 of embodiment 3 of the present invention to the lower end of the joint mullion 16d of the externally movable single-sliding window 1 shown in Figures 1 to 3, first the lower first blocking member 31 that constitutes this upright blocking member 3 is fixed to the lower end of the joint mullion 16d with screws, and then the lower second blocking member 32 is attached to the fixed lower first blocking member 31, as shown in Figures 19 and 20.

[0068] In this case, the positioning protrusion 31a4 on the inner side of the lower first blocking movable screen side portion 31a of the lower first blocking member 31 can be passed through the screw hole of the metal member 16d1 of the joining mullion 16d to position it, and then the lower first blocking member 31 can be fixed to the joining mullion 16d with a screw, thereby improving the ease of installation.

[0069] Furthermore, when the lower second blocking member 32 is attached to the lower first blocking member 31, the fitting projections 32a, 32a on the upper side of the lower second blocking member 32 are fitted into a pair of mounting holes 16d21, 16d21 (see Figs. 19 and 20) formed in the resin cover 16d2 of the joint mullion 16d, and the pair of fitting pieces 32b, 32b on the lower side of the lower second blocking member 32 are fitted into a pair of fitted pieces 31b2, 31b2 on the lower first blocking room inner side portion 31b of the lower first blocking member 31. This completes the attachment of the lower second blocking member 32 to the lower first blocking member 31, and therefore the attachment of the mullion blocking member 3 of embodiment 3 to the joint mullion 16d.

[0070] When performing maintenance work on the joining mullion 16d, such as replacing the plastic cover 16d2 of the joining mullion 16d, the maintenance work for the joining mullion 16d can be performed by performing the reverse procedure to the installation work of the mullion closing member 3 in the embodiment 3 described above at the lower end of the joining mullion 16d, i.e., first removing the lower second closing member 32 from the lower first closing member 31, and then removing the screws to remove the lower first closing member 31 from the joining mullion 16d, and replacing the plastic cover 16d2 of the joining mullion 16d, etc.

[0071] Furthermore, when removing the lower second blocking member 32 from the lower first blocking member 31, the lower second blocking member 32 can be easily removed by inserting the tip of a tool or the like into the working recess 31c2 of the lower first blocking lower side portion 31c and pulling it, or by raising the tool or the like.

[0072] <Summary of the mullion blocking member 3 according to the third embodiment of the present invention> As described above, the mullion blocking member 3 of embodiment 3 of the present invention is fixed to the mating mullion 16d of the externally movable sliding window 1 and comprises an upper first blocking member 21 made of resin and provided with mating pieces 31b2, 31b2 into which the mating pieces 32b, 32b of the lower second blocking member 32 fit, and a lower second blocking member 32 made of resin and provided with mating pieces 32b, 32b that fit into the mating pieces 31b2, 31b2 of the lower first blocking member 31 and attached to the lower first blocking member 31 so as to cover the mating pieces 31b2, 31b2.

[0073] Therefore, the mullion blocking member 3 of embodiment 3 is divided into two members, the lower first blocking member 31 and the lower second blocking member 32, and the lower second blocking member 32 is attached to the lower first blocking member 31 by engaging the engaging pieces 32b, 32b with the engaged pieces 31b2, 31b2. Therefore, it can be easily removed from the joint mullion 16d of the external sliding window 1, and maintenance work on the joint mullion 16d, such as replacing the plastic cover 16d2 of the joint mullion 16d of the external sliding window 1, can be easily performed.

[0074] In particular, the lower second blocking member 32 is provided on the lower first blocking room inner side portion 31b of the lower first blocking member 31, and hides the head of the screw that fixes the lower first blocking member 31 to the joining mullion 16d and the screw through hole 31b1 through which the screw passes, thereby improving the design.

[0075] In addition, in the mullion blocking member 3 of embodiment 3 of the present invention, a positioning protrusion 31a4 is provided on the inside of the lower first blocking movable screen side portion 31a for passing through the screw hole of the metal member 16d1 of the joining mullion 16d for positioning, etc.

[0076] Therefore, when attaching the lower first blocking member 31 to the joint post 16d, the positioning protrusion 31a4 makes it easy to position the lower first blocking member 31 to the joint post 16d, thereby improving the ease of installation of the post blocking member 3.

[0077] In addition, in the mullion blocking member 3 of embodiment 3 of the present invention, a rubber frame side airtight material 12c is provided on the lower frame 12 of the externally movable single-sliding window 1 along each rail 12a1 at least near the joint mullion 16d, while a blocking member side airtight material 31a3 is provided on the lower first blocking member 31 which elastically contacts the frame side airtight material 12c of the lower frame 12.

[0078] Therefore, when the mullion blocking member 3 of embodiment 3 is attached to the joint mullion 16d, the lower end of the blocking member side airtight material 31a3 of the lower first blocking member 31 elastically contacts the frame side airtight material 12c at the lower end of the joint mullion 16d, thereby further improving the airtightness and watertightness of the lower end of the joint mullion 16d of the externally movable single-sliding window 1.

[0079] In the explanation of the above embodiment 3, as in the above embodiments 1 and 2, an externally movable sliding window 1 has been described as having one exterior movable shoji screen 15 that can be opened and closed on one side of the interior fixed shoji screen 16 shown in Figure 1. However, the mullion blocking member 3 of embodiment 3 is not limited to this and can be applied, for example, to an externally movable sliding window 1' having exterior movable shoji screens 15' on both sides of an interior fixed shoji screen 16' shown in Figure 10.

[0080] Embodiment 4 Next, we will explain the mullion blocking member 3' of embodiment 4 according to the present invention. In the explanation of the mullion blocking member 3 of embodiment 3 above, we have taken as an example the mullion blocking member 3 that is attached to the lower end of the joint mullion 16d of an externally movable single-sliding window that has a small height and protrudes only a little toward the inside of the room, as shown in Figures 2 and 3. However, in the mullion blocking member 3' of embodiment 4, we will explain a mullion blocking member that is attached to the joint mullion 16d''' of an externally movable single-sliding window 1" that has a large height and protrudes only a little toward the inside of the room, as shown in Figures 11 and 12, similar to the mullion blocking member 2' of embodiment 2.

[0081] Therefore, in the upright blocking member 3' of embodiment 4 of the present invention, the lower first blocking member is the same as the lower first blocking member 31 of the upright blocking member 3 of embodiment 3 described above, and only the lower second blocking member 32' is different.

[0082] Figures 21(a) and (b) are respectively a plan view and a right side view of an upper second blocking member 32' constituting a mullion blocking member 3' of embodiment 4 of the present invention, which is attached to the lower end of the joint mullion 16d" of the external sliding window 1" shown in Figures 11 and 12. Also, Figures 22(a) and (b) are respectively a front view and a back view of an upper second blocking member 32' constituting a mullion blocking member 3' of embodiment 4 of the present invention.

[0083] The lower second blocking member 32' constituting the mullion blocking member 3' of embodiment 4 is attached to the lower first blocking member 31 of the mullion blocking member 3 of embodiment 3 fixed to the lower end of the joint mullion 16d" of the external sliding window 1" shown in Figures 11 and 12. Therefore, although the apparent dimension, which is the width, is the same as that of the lower second blocking member 32 (see Figure 18) constituting the mullion blocking member 3 of embodiment 3, the apparent dimension, which is the amount of protrusion toward the room of the metal member 16d1" and the resin cover 16d2" constituting the joint mullion 16d", is large, so that the lower first blocking member 31, as shown in Figures 21(a), (b) and Figures 22(a), (b), 21(b), it is configured in an L-shape as shown in FIG. 21(b), and is composed of a lower second blocking indoor side portion 32a' which is attached so as to face the lower first blocking indoor side portion 31b (see FIG. 16 and FIG. 17), a lower second blocking lower side portion 32b' which bends 90 degrees from the upper end of the lower second blocking indoor side portion 32a' and extends toward the inside of the room to cover the lower end of the joining mullion 16d'', lower second blocking left and right upright surface portions 32c', 32c' which rise up small from both the left and right ends of the lower second blocking lower side portion 32b', and a lower second blocking front upright surface portion 32d' which rises small from the front end portion on the inside of the room of the lower second blocking lower side portion 32b'.

[0084] The lower second blocked room side portion 32a' is provided with a pair of mating pieces 32a1', 32a1' which fit into a pair of mating pieces 31b2, 31b2 (see Figures 16, 17(a), etc.) of the lower first blocked room side portion 31b, while the lower second blocked front upright surface portion 32d' is provided with a pair of mating protrusions 32d1', 32d1' which fit into a pair of mounting holes 16d21", 16d21" (see Figure 23) provided in the resin cover 16d2" of the joint mullion 16d".

[0085] In other words, in embodiment 4, the mating pieces 32a1', 32a1' of the lower second blocking room inner side portion 32a' correspond to the mating pieces 32b, 32b at the lower part of the lower second blocking member 32 in embodiment 3, while the mating protrusions 32d1', 32d1' of the lower second blocking front upright surface portion 32d' correspond to the mating protrusions 32a, 32a at the upper part of the lower second blocking member 32 in embodiment 3.

[0086] The lower second blocking member 32' of embodiment 4 configured as described above and the lower first blocking member 31 of embodiment 3 can be used to form the mullion blocking member 3' of embodiment 4 of the present invention, and when the mullion blocking member 3' of embodiment 4 consisting of such two members is used to attach the lower end of the joint mullion 16d" of the external sliding window 1" shown in Figures 11 and 12, the mullion blocking member 3' of embodiment 4 of the present invention can be installed as shown in Figures 23 and 24.

[0087] <Summary of the mullion blocking member 3' according to the fourth embodiment of the present invention> Therefore, according to the mullion closing member 3' of embodiment 4 of the present invention, like the mullion closing member 3 of embodiment 3, the mullion closing member covering the lower end of the joint mullion 16d" is divided into two members, the lower first closing member 31 and the lower second closing member 32', so that it can be easily removed from the joint mullion 16d" like the mullion closing member 3 of embodiment 3, and maintenance work on the joint mullion 16d" such as replacing the resin cover 16d2" of the joint mullion 16d" can be easily performed.

[0088] In particular, in the upright blocking member 3' of embodiment 4, the lower first blocking member 31 can be the same as the lower first blocking member 31 of the upright blocking member 3 of embodiment 3, and only the lower second blocking member 32' needs to be prepared as a different member, thereby reducing manufacturing costs and management costs.

[0089] Furthermore, like the mullion blocking member 3 of embodiment 3, the mullion blocking member 3' of embodiment 4 can be applied not only to an externally movable single-sliding window 1 having an externally movable shoji screen 15 that can be opened and closed on one side of an internally fixed shoji screen 16 as shown in Figure 1, but can also be applied to an externally movable single-sliding window 1' having an externally movable shoji screen 15' on each side of an internally fixed shoji screen 16' as shown in Figure 10, when a joining mullion 16d'' with a large amount of protrusion toward the internal side as described above is used.
