  Next, the operation of the interlocking member 50 will be described. FIG. 8 is a cross-sectional view schematically showing how the shojis 21 to 23 move in conjunction with the interlocking member 50. FIG. 8A shows an opening that communicates the indoor / outdoor space with the three shojis 21 to 23. (B) shows a state where a part of the opening is opened, and (C) shows a state where the opening is closed.

  When the shoji 21 is slid in the direction of the arrow A as shown in FIG. 8B from the state in which the shoji 21 to 23 shown in FIG. 8A are closed, the guide shaft member 54B is moved in the direction of the arrow A. , The wire 53 stretched between the reels 52 rotates, and the guide shaft member 54A moves in the direction of arrow B. When the guide shaft member 54 </ b> A moves in the direction of arrow B, the shoji 23 is in a fixed state, and therefore, the muffler 22 moves in the direction of arrow A. Accordingly, the inner shoji 21 and the middle shoji 22 move in the direction of the arrow A in the figure, and finally, as shown in FIG. 8 (C), the three shoji 21-21 overlap each other. Thus, the open state shown in FIG. 5 is obtained.

  On the other hand, when the inner shoji 21 is slid in the direction of arrow B in FIG. 8 from the open state shown in FIG. 5, the interlocking member 50 acts in the opposite direction to the above and is completely closed as shown in FIG. It becomes a state. With such an interlocking member 50, the sliding door 20 can be slid in an interlocking manner only by sliding the inner sliding door 21, and the opening and closing of the sliding door 20 is facilitated.

  9 is a cross-sectional view taken along the line IX-IX in FIG. As shown in FIG. 9, a projecting portion 61 that projects indoors is integrally formed on the summon cage 222 of the shoji 22. The protrusion 61 has a groove 61A formed on the upper side. The second rail 11 </ b> A for sliding the inner impeller 21 is engaged with the groove 61 </ b> A. For this reason, as shown in FIG. 2, the summon bowl 222 including the protrusion part 61 is arrange | positioned so that two rails 11A and 11B may be straddled. Thus, the protrusion 61 is formed in the summon bowl 222, and the strength of the summon bowl 222 is increased. In addition, by engaging the groove 61A and the second rail 11A for the inner shroud 21, the strength of the summon cage 222 in the indoor / outdoor direction is improved, and the wind resistance of the middle shoji 22 can be improved.

  In the present embodiment, the protruding portion 61 is provided only on the summing bowl 222 of the shoji 22. However, the projecting section 221 of the shoji 22 projects to the outdoor side and has a groove formed on the upper side. The strength of the summoning bar 221 may be improved by forming a portion and engaging the groove with the first rail 11C for the external shoji 23. Moreover, although the rails 11A and 11B formed on the upper frame 11 were used to suppress the rattling of the middle shoji 22, the lower frame 12 was provided with rails corresponding to the shojis 21 to 23, respectively. By using the same structure as the rails 11A, 11B, and 11C of the upper frame 11, the rail may be used as a reinforcing portion to suppress the rattling of the shoji 20 in the expected direction.

As shown in FIG. 9, the windshield plate 70 is attached to the upper frame 11 at the summing position between the third rail 11 </ b> B for the middle shoji 22 and the first rail 11 </ b> C for the outer shoji 23. .
FIG. 10 is a perspective view showing the windshield plate 70. As shown in FIG. 10, the windshield 70 includes an upper plate 71 attached to the upper frame 11, a plurality of windshield main bodies 72 erected at intervals in the longitudinal direction of the upper plate 71, and an upper plate. 71 is provided with two fin portions 73 erected at both ends in the width direction. The windshield main body 72 is in contact with the upper arm 24 of the middle shoji 22 and the upper arm 24 of the outer shoji 23 to prevent intrusion of wind from the gap between the upper frame 11 and the shoji 22, 22 and sound leakage. is doing.

  As shown in FIG. 9, the outdoor fin portion 73 (73 </ b> A) engages with the groove portion of the upper sliding piece 62 attached to the upper collar 24 of the external shingles 23, and the indoor fin portion 73 (73 </ b> B). Is engaged with the groove portion of the upper sliding piece 63 attached to the upper collar 24 of the middle shovel 22. Such engagement between the fin portion 73 and the upper sliding pieces 62 and 63 can prevent the shoji 20 from rattling in the indoor / outdoor direction.

  In addition, although illustration is abbreviate | omitted, the wind-shield board 70 is attached also to the summing position between the rail 11B for the middle shoji 22 and the rail 11A for the inner shoji 21. Similarly, the windshield plate 70 is also attached to the lower frame 12.

  In addition, as shown in FIG. 4, an attracting piece 80 is attached to the door toe tub 211 of the inner shoji 21. A plurality of attracting pieces 80 are attached at intervals along the longitudinal direction of the door toe fence 211. The attracting piece 80 is formed with a groove portion 80A that accommodates and engages the first fin portion 131 of the vertical frame 13L when the inner shroud 21 is closed. Thereby, it is possible to prevent the inner shoji 21 from opening from the vertical frame 13L.

According to this embodiment, there are the following effects.
(1) The fin portions 131, 132, 135 are formed in any of the vertical frames 13R, 13L. For example, one vertical frame 13 (13R) is attached to the first fin portion 131 and the second fin portion 132. The member 133 is attached, and the seal material 134 is attached to the second fin portion 132 for the other vertical frame 13 (13L). For this reason, by replacing the attachment member 133 and the sealing material 134 with the vertical frame 13 on the opposite side, the frame body 10 is removed from the building 2 and replaced with different shojis with left and right hands while using the frame body 10. It is possible to easily change the left and right hand of the shoji 20 by simply.

  (2) At this time, since the external obstacle 23 is fixed, the third fin portion 135 does not hinder the function of the external obstacle 23, and the first fin portion 131 and the second fin portion 132 are Since it is covered with the attachment member 133, even if the inner limb 21 slides to the right in FIG. 4, the sump 212 of the inner limb 21 abuts against the surface of the attachment member 133. , 132 does not hinder the sliding of the inner shoji 21. Therefore, even if the fin portions 131, 132, 135 are provided in the left and right vertical frames 13L, 13R, respectively, the functions of the inner limb 21 and the outer limb 23 are not hindered. Can easily handle different types of shoji.

  (3) The inner surface of the vertical frame 13R is covered at a position corresponding to the sliding position of the inner impingement element 21 in the vertical frame 13R, and the surface thereof is substantially the same as the surface on the prospective direction side of the door toe 232 of the outer obstacle 23 Since the attachment member 133 that is the same is attached, the attachment member 133 hides almost the inner side surface of the vertical frame 13R and the surface of the door toe 232 of the door pad 232 of the shoji 23 so that it feels open from the indoor side. Can be further improved.

  (4) When the door toe 232 of the external shoji 23 is stored in the vertical frame 13R, the finding size of the door toe 232 and the insertion size of the vertical frame 13R are substantially the same. When the door is closed, the door toe 232 is properly housed in the vertical frame 13R and hidden. For this reason, when the outside of the shoji 20 is closed and the outdoor side is viewed from the room side, the heel portion that blocks the field of view is reduced, so that the feeling of opening in the room can be further improved.

  (5) Since the finding dimensions P and Q of the summon bowls 221 and 222 are approximately twice the penetration dimension R of the double glazing 28 and 40 mm or less, Since it becomes smaller than the case of the combination, the ratio of the summons 221 and 222 to the shoji 20 is reduced, and the feeling of opening from the indoor side can be further improved.

As shown in FIG. 11, the spacer 100 may be attached to the summing bar 222 of the middle shoji 22 so that the spacer 100 urges the indoor side surface of the summing bar 231 of the outer shoji 23 toward the outdoor side. According to such a configuration, rattling of the shoji 20 in the indoor / outdoor direction can be suppressed.

  Further, a protrusion 41 as shown in FIG. 11 is formed on each of the upper sliding piece and the lower sliding piece, and when the shoji 20 is closed, the projecting portion 41 becomes a smoke on the right side of the middle shoji 22. You may make it interpose in the up-and-down position between return part 22X and smoke return part 23X of external shoji 23. Moreover, although illustration is abbreviate | omitted, the protrusion part is inserted in the up-and-down position between the smoke return part 22 of the inner shrimp and the smoke return part similarly also about the left side part of the media. It may be. According to such a configuration, when the shoji 20 is closed, the protrusion 41 is interposed in the clearance between the smoke return portions 22X and 23X, and each clearance portion is blocked at its upper and lower positions. It is possible to suppress rattling in the direction of finding 21 to 23.

  FIG. 12 is a longitudinal sectional view showing the lower side of the sliding door. FIG. 13 is a cross-sectional view partially showing the sliding door. As shown in FIGS. 12 and 13, the stopper member 110 may be attached to the lower frame 12 at a position corresponding to the neutral paper 22. When the shoji 20 is closed, the stopper member 110 comes into contact with the lower collar 25 of the middle shovel 22 and urges the lower arm 25 of the middle shoji 22 to the right in FIG. With such a configuration, when the shoji 20 is closed, the clearance formed between the smoke return portion of the inner shoji 21 and the smoke return portion of the middle shoji 22 can be reduced, and the shoji 20 can be found. Shaking in the direction can be suppressed.

  Moreover, in the said embodiment, although the sliding door 1 was comprised as a triple door, as shown in FIG. 14, using the same frame 10 as the said embodiment, the two shojis 102 and 103 and the one screen door are used. It is good also as the sliding door 101 provided with 104. FIG.
