  When the shoji 20 is in the closed position and the slide plate 51 is in the engaged position, the receiving surface (engaging portion) 962 of the anti-warpage receiving bracket 96 with respect to the engaging portion 953 of the anti-warpage metal 95 is a chamber. It is located outside. That is, the warpage preventing fitting 95 and the warpage preventing receiving fitting 96 have a positional relationship of overlapping in the expected direction (see FIG. 16).

  As shown in FIG. 17, the length from the engagement position (set position) where the lock pin 52 engages with the notch 163 of the lock pin receiving bracket 16 to the release position where the lock pin 52 disengages from the notch 163 is a length d1. Do. The lock pin 52 of the present embodiment is configured to include a shaft portion 521 fixed to the slide plate 51 and a retaining portion 522 having a diameter larger than that of the shaft portion 521 (see FIG. 11). In the present embodiment, the shaft portion 521 is a position designed to interfere with the cutout portion 163, and the shaft portion 521 is positioned on the front side of the rear side of the cutout portion 163. That is, the engagement position does not have to be located on the far side of the cutout portion 163.

  Next, the shape of the cutout portion 163 as a holding portion for holding the lock pin 52 and the engagement relationship of the lock pin will be described. FIG. 18 is an enlarged view showing the notch portion 163 of the lock pin bracket 16 of the present embodiment from the door tip side vertical frame 14 side. As shown in FIG. 18, the cutaway portion 163 as the holding portion has an inclined portion 163a, a straight portion 163b, and an arc portion 163c. The arc portion 163 c is located at the deepest side of the notch portion 163 and is a portion that restricts the upward movement of the lock pin 52. The straight portion 163b is located on the outdoor side of the arc portion 163c (on the side where the shoji 20 opens), and restricts the movement of the shaft portion 521 of the lock pin 52 in the expected direction. The inclined portion 163a is located on the outer side of the entrance of the cutout portion 163, and is inclined toward the outer side as it descends from the lower end of the straight portion 163b.

  In the notch portion 163, when the shaft portion 521 of the lock pin 52 is located in the range of the length L1 excluding the inclined portion 163a, the shaft portion is extended by the linear portion 163b extending in the direction orthogonal to the movement direction The movement of 521 is reliably blocked. In the above-described engagement position, the center of the shaft portion 521 of the lock pin 52 is in the range of the length L2 of the linear portion 163b. When the shaft portion 521 of the lock pin 52 moves by the length L3 from the engaged position, it reaches the inclined portion 163a. As long as it is within the range of the length L2 of the notch portion 163, the movement of the shaft portion 521 is blocked by the straight portion 163b extending in the orthogonal direction.

  On the other hand, the length in the vertical direction (splashing margin) in the range in which the warpage preventing fitting 95 and the warpage preventing fitting 96 overlap in the expected direction is taken as a length d2 (see FIG. 17). In the present embodiment, the length d2 of the hooking margin of the warpage preventing fitting 95 and the warpage preventing fitting 96 is longer than the length L2 of the straight portion 163b. When the relationship of length d2> length L2 holds, the door tip side of the shoji 20 falls by melting at the time of fire occurrence, the center of the shaft portion 521 falls to the position of the inclined portion 163a, and the length of the linear portion 163b Even if it deviates from the range of L2, the opening of the shoji 20 can be reliably prevented by the anti-curvature fitting 95 and the anti-curvature receiving bracket 96 in the range of the length d2 of the engagement margin.

  Further, as shown in FIG. 17, the shaft portion 521 separates from the notch portion 163 from the engagement position where the shaft portion 521 has entered the inside of the notch portion 163 and does not interfere with the notch portion 163 including the inclined portion 163 a when the shoji 20 opens. Let the distance to the position be length d1. In the present embodiment, the shapes and mounting positions of the warpage preventing metal fitting 95 and the warpage preventing bracket 96 are set such that the length d2 is longer than the length d1. That is, the relationship of length d2> length d1 is also established. By this, even when the door tip side of the shoji 20 falls below the length L2 and the lock pin 52 is about to release the engagement of the lock pin receiving bracket 16, the engagement of the anti-warp 95 and the anti-warp 96 is achieved. Opening of the shoji 20 can be prevented. In the ordinary opening operation of the shoji 20, the slide plate 51 is moved downward by the handle mechanism 57 so as to exceed the range of the length d2. Will not interfere.

According to the configuration of the embodiment described above, the following effects can be obtained.
The fixture 1 includes a resin-made door tip side longitudinal bar 34 located on the door tip side of the shoji 20, and a door tip side longitudinal frame 14 facing the door tip side longitudinal bar 34 with the shoji 20 in the closed position; It is fixed to the door tip side vertical frame 34, and is fixed to the slide pin 51 slidably movable in the longitudinal direction of the door tip side vertical rod 34, the lock pin 52 fixed to the slide plate 51, and the door tip side vertical frame 14 The lock pin bracket 16 having a notch 163 for restricting movement of the lock pin 52 toward the opening side (outdoor side) in the expected direction with the lock 20 in the closed position, and the door front side vertical frame 14 An anti-warpage receiving bracket 96 having a receiving surface (piece) 962 fixed to the door-end-side vertical frame 14 and projecting toward the door-end-side vertical frame, and a warpage preventing bracket 95 fixed to the slide plate 51; Inclined from the engagement position at the notch 163 The length d2 of the range in which the receiving surface 962 and the anti-warp metal fitting 95 overlap in the expected direction is greater than the length L2 of the range (linear portion 163b) that restricts the movement of the lock pin 52 in the expected direction up to the portion 163a. Configured long.

  As a result, even if warpage occurs in the resin-made door tip side vertical weir 34 at the time of fire occurrence, the door tip side vertical wedging 34 is further reversed by the engagement of the warpage prevention receiving bracket 96 and the warpage preventing metal fitting 95. Therefore, a gap is generated between the shoji 20 and the frame 10 due to the warpage, and the occurrence of a situation in which the flame penetrates the outdoor side and the indoor side can be reliably prevented. Further, even if the door tip side of the shoji 20 lowers when the fire occurs and the position of the lock pin 52 is lowered by the length d1 and the lock pin 52 is about to be detached from the lock pin receiving bracket 16, the receiving surface 962 and the warp preventing bracket 95 Is longer than the length L2 of the straight portion 163b of the notch 163 and the length d1 until the notch 163 is released from the engagement position, Can be prevented or delayed. Further, in the case of the open-out fixture 1, if there is a flame source on the outdoor side, the door tip side vertical weir 34 is easily warped and the outdoor and indoor sides are more easily penetrated. The warpage of the door-side vertical weir 34 can be reliably prevented by the prevention bracket 96 and the warpage prevention bracket 95, which is more preferable.

  Further, in the present embodiment, the lock pin 52 and the lock pin bracket 16 are disposed at two locations (plural), and the anti-warpage bracket 96 is positioned between the lock pin brackets 16 disposed at the upper and lower two locations, The warpage prevention metal fitting 95 is located between the lock pins 52 disposed at the upper and lower two places.

  As a result, the anti-warp 95 and the anti-warp bracket 96 are disposed at positions where warpage is likely to occur in the door-side vertical frame 14 and the door-side vertical weir 34 at the time of fire occurrence. Warpage of the crucible 34 can be prevented more reliably at an early stage.

  Further, in the present embodiment, the warpage preventing metal fitting 95 is a fixing portion 951 fixed to the expected surface of the slide plate 51 and an engagement member protruding from the fixing portion 951 toward the door tip side vertical frame 14 in the closed state of the shoji 20. And a joint 953.

  Thereby, a configuration can be realized that prevents the opening of the shoji 20 at the time of a fire occurrence while avoiding the situation where the fixing portion 951 interferes with the receiving surface 962 of the warpage prevention receiving bracket 96 when the shoji 20 is opened. Further, in the present embodiment, when the slide plate 51 moves to the disengaging position, the fixing portion 951 moves in the direction away from the warpage prevention receiving bracket 96, so the warpage prevention bracket 95 when the shoji 20 is opened Interference of the warpage preventing bracket 96 can be more reliably avoided.

  As described above, in the present embodiment, the core material connecting fitting 70 disposed in the upper frame 31 and the core material connecting bracket 71 disposed in the door-end-side vertical bar 34 have different shapes. A suitable shape according to is adopted. The base member 315 may be omitted in the upper collar 31 or the core connection fitting 71 may be disposed in a portion of the fitting groove 31 j without the pedestal 315, and the slide plate 51 does not interfere with the door tip side vertical rib 34. It is good also as composition which arranges pedestal part 315 of length and arranges core material connection fitting 70.

  In the above embodiment, the thickness of the door tip side vertical weir 34 is secured by the hollow portion 34 a on the outdoor side and the hollow portion 34 b on the indoor side, and the slide plate 51 is the door front surface of the door tip side vertical wed 34 In the expected direction and approximately at the center. As a result, the slide plate 51 does not easily separate from the door side vertical weir 34 regardless of whether the flame source is the outdoor side or the indoor side. In addition, separation of the housing 30 to the indoor side is prevented by the core connection fittings 70 and 71. As described above, since the warpage preventing metal fitting 95 is fixed to the slide plate 51 which is held firmly even in the event of a fire, a configuration is realized in which the warpage of the door tip side longitudinal weir 34 can be prevented more reliably.

  A modification of the above embodiment will be described. In the following description, the same or similar configuration as or to that of the above embodiment may be denoted by the same reference numeral and the description thereof may be omitted.

  FIG. 19 is a perspective view showing the warpage prevention metal fitting 97 fixed to the slide plate 51a of the modification and the periphery thereof. In this modification, the method of fixing the warpage prevention metal fitting 97 to the slide plate 51a is different from that of the above embodiment. The configuration of the warpage preventing fitting 97 is the same as the configuration of the warpage preventing fitting 95 of the above embodiment, and is composed of a fixing portion 951, an inclined portion 952, an engaging portion 953, and a bending portion 954.

  As shown in FIG. 19, through holes 98 for attaching the anti-warp metal fitting 97 are separately formed in the slide plate 51a of the modification. The warpage preventing fitting 97 is set on the back side of the slide plate 51 a so that the engaging portion 953 protrudes from the through hole 98. In the warpage prevention fitting 97, a fixing portion 951 located on the back side of the slide plate 51a is fastened and fixed from the surface of the slide plate 51a by a screw 956.

  That is, the through hole 98 for attaching the anti-warpage fitting 97 is formed in the slide plate 51a of the fitting 1 of the modification, and the anti-warpage fitting 97 is formed from the fixing portion 951 and the fixing portion 951 located on the back side And an engaging portion 953 protruding to the door tip side through the through hole 98.

  Also by the warpage preventing fitting 97 of this modification, the same effect as the warpage preventing fitting 95 of the above embodiment can be obtained. In addition, since it is not necessary to prepare the back plate 955 for fixing the anti-warpage fitting 97 to the slide plate 51a, it is possible to realize the anti-warpage of the door tip side vertical weir 34 with a simple configuration. Further, in the work of fixing the warpage prevention metal fitting 97 to the slide plate 51a, it is not necessary to perform the fastening work while holding the back plate, so that the working process can be simplified.

  As mentioned above, although the preferable embodiment of this invention was described, this invention is not restrict | limited to the above-mentioned embodiment and modification, It can change suitably. For example, although the frame 10 and the housing 30 of the above-described embodiment are both made of resin, metal such as aluminum is used for at least one of the expected direction outer side and the indoor side of the frame 10 and the housing 30. The cover member of the above may be additionally disposed. That is, the metal frame may be attached to the inside, the indoor side, or the outdoor side of the resin frame and the resin frame. Further, the present invention is not limited to the resin frame or frame, but can be applied to a metal frame or frame such as aluminum, a sash of aluminum resin composite, and the like. Moreover, in the said embodiment, although the lock pin and the lock pin receptacle are arrange | positioned at two upper and lower sides, it is not necessarily limited to this structure. For example, three or more lock pins and lock pin receptacles may be arranged.

  Further, in the above embodiment, the self-opening door has been described as an example of the fitting according to the present invention, but the invention is not limited to this configuration. Various types of swing door such as swing door The present invention can be applied to a fitting.
