[0004] However, in the event of a fire, the shoji screen may swell, warp, and twist, and the fireproof structure of the window described in Patent Document 1 was not able to adequately prevent this.

[0005] The present disclosure aims to provide anti-warping fittings that can suppress warping and twisting of shoji screens. [Means for solving the problem]

[0006] The present disclosure relates to a warp prevention fitting that prevents warping of a shoji screen, the warp prevention fitting having a base that is attached to the outer peripheral surface of the shoji screen and a wall that rises from the base on the outdoor side of the outer peripheral surface of the shoji screen.

[0008] Below, we will explain the horizontal sliding window 1 as a fixture according to an embodiment of the present disclosure. In the following explanation, the projection direction is the direction along the depth of the fixture, with the back side in Figure 1 being referred to as the outside side X1 and the front side being referred to as the inside side X2. The surface along the projection direction may be referred to as the projection surface. The projection direction is the direction along the face direction of the window surface of the horizontal sliding window 1. The surface along the projection direction may be referred to as the projection surface.

[0009] As shown in Figures 1 to 3, a horizontal sliding window 1 has a frame 2 that is attached to an opening in a building frame, a shoji screen 3 that is housed inside the frame 2, a screen door 4, an operator handle 5, and a warp prevention mechanism 6. The frame 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of vertical frames 23, 24 in a rectangular shape.

[0010] As shown in FIGS. 2 and 3, the upper frame 21, the lower frame 22, and the vertical frames 23 and 24 have metal frames 211, 221, 231, and 241, and resin covers 212, 222, 232, and 242, respectively.

[0011] The metal frames 211, 221, 231, and 241 are provided to cover the visible surface of the opening in the building skeleton on the outside side X1. The resin covers 212, 222, 232, and 242 are provided on the inner periphery of the metal frames 211, 221, 231, and 241 on the inside side X2 of the metal frames 211, 221, 231, and 241. The periphery of the screen door 4, which is placed on the inside side X2 of the shoji screen 3, is attached to the inner periphery of the resin covers 212, 222, 232, and 242.

[0012] The shoji screen 3 is arranged so as to be able to open and close on the inner periphery of the frame body 2. The shoji screen 3 is formed by fitting a glass panel 35 made of one or more glass plates inside a rectangular frame body made of an upper frame 31, a lower frame 32, and left and right vertical frames 33, 34.

[0013] As shown in Figure 2, the operator handle 5 is provided on the lower frame 22 of the frame body 2. The operator handle 5 transmits a rotational force to the shoji screen 3 via an operating arm 51, thereby enabling the shoji screen 3 to be opened or closed.

[0014] 1 and 3, a pair of link mechanisms 36 that support the opening and closing operation of the shoji screen 3 are provided on the left and right sides of the upper end of the shoji screen 3. One link mechanism 36 connects the vertical stile 33 to the vertical frame 23, and the other link mechanism 36 connects the vertical stile 34 to the vertical frame 24.

[0015] As shown in Fig. 3, each of the pair of link mechanisms 36 includes a stay 361 and an arm 362. The stay 361 is attached to mounting portions 231a, 241a extending in the forward direction of the metal frames 231, 241 of the vertical frames 23, 24. One end of the arm 362 is rotatably supported by the stay 361, and the other end is rotatably supported by the vertical frames 33, 34. When the operator handle 5 is used to open or close the shoji screen 3, the link mechanism 36 causes the arm 362 to rotate relative to the vertical frames 23, 24 and the vertical frames 33, 34 in conjunction with the arm 362, thereby allowing the shoji screen 3 to open and close smoothly and reliably.

[0016] The warp prevention mechanism 6 prevents the shoji screen 3 from warping and twisting by restricting its movement toward the outside X1 and restricting the rotation of the upper frame 31 of the shoji screen 3 when the shoji screen 3 swells, warps, and twists during a fire or other event. As shown in FIG. 4 , the warp prevention mechanism 6 includes a warp prevention bracket 7 provided on the upper frame 21 and a warp prevention bracket 8 provided on the upper frame 31 of the shoji screen 3.

[0017] The warp prevention receiving bracket 7 is fixed to the inner periphery of the lower plate 211a, which is part of the metal frame 211 of the upper frame 21. The warp prevention receiving bracket 7 has an L-shaped cross section and extends in the longitudinal direction of the upper frame 21. The warp prevention receiving bracket 7 has a base plate 71 fixed to the inner periphery of the lower plate 211a, and a receiving wall portion 72 protruding downward from the end of the base plate 71 on the outdoor side X1.

[0018] The warp prevention fitting 8 is fixed to the upper frame 31 below the warp prevention receiving fitting 7. As shown in Figures 4 and 5, the warp prevention fitting 8 has a base portion 81 (base) attached to the upper surface (outer peripheral surface) of the upper panel 311 which is part of the upper frame 31 of the shoji screen 3, an indoor side wall portion 82 which stands up from the indoor side X2 end of the base portion 81 towards the upper frame 21, and a pair of outdoor side wall portions 83 (wall portions) which are provided at both longitudinal ends of the base portion 81 and stand up from the outdoor side X1 of the base portion 81.

[0019] The base plate portion 81 is disposed so as to cover the upper surface of the upper panel 311. That is, the base plate portion 81 is formed in the shape of a long plate extending in the longitudinal direction of the upper frame 31 of the shoji screen 3.

[0020] The indoor wall portion 82 is formed in the shape of a plate having a thickness in the indoor-outdoor direction, and extends in the longitudinal direction of the upper frame 31 of the shoji screen 3. The indoor wall portion 82 has a predetermined height, and its upper end is located above the lower end of the receiving wall portion 72 of the warp prevention receiving bracket 7. When the shoji screen 3 swells and warps in the event of a fire or other such event, causing the shoji screen 3 to deform and move to the outdoor side X1, the indoor wall portion 82 collides with the receiving wall portion 72 of the warp prevention receiving bracket 7. This restricts the shoji screen 3 from moving to the outdoor side X1, and prevents the shoji screen 3 from warping.

[0021] The outdoor wall portion 83 stands up from the base portion 81 and extends in the indoor / outdoor direction (projection direction) on the outdoor side X1 of the upper surface (outer peripheral surface) of the top plate 311. The outdoor wall portion 83 is formed in the shape of a plate having a thickness in the longitudinal direction of the base portion 81, extends a predetermined length in the indoor / outdoor direction, and has a predetermined height.

[0022] When the shoji screen 3 bulges, warps, and twists, applying a rotating force to the upper frame 31, the upper end faces 831 of the pair of outdoor wall sections 83 arranged on both longitudinal ends of the upper frame 31 collide with the inner peripheral surface of the lower panel 211a of the upper frame 21, as shown in Figure 6. This restricts the rotation of the upper frame 31 and prevents warping and twisting of the shoji screen 3. By extending the pair of outdoor wall sections 83 in the indoor / outdoor direction, even if the shoji screen 3 warps and rotates toward the outdoor side X1 in the event of a fire, for example, the pair of outdoor wall sections 83 are more likely to collide with the inner peripheral surface of the lower panel 211a of the upper frame 21, thereby more effectively restricting the rotation of the upper frame 31.

[0023] This embodiment has the following advantages: The warp prevention fitting 8 has a base 81 attached to the outer peripheral surface of the shoji screen 3, and an outdoor wall portion 83 that stands up from the base 81 on the outdoor side X1 of the outer peripheral surface of the shoji screen 3 and extends in the viewing direction.

[0024] As a result, when the shoji screen 3 bulges, warps, and twists, and a rotating force is applied to the upper frame 31, the upper end faces 831 of the pair of outdoor wall portions 83 collide with the inner peripheral surface of the lower panel 211a of the upper frame 21, thereby restricting the rotation of the upper frame 31. Therefore, the shoji screen 3 can be prevented from warping and twisting.

[0025] Furthermore, in this embodiment, the outdoor wall sections 83 are located at both longitudinal ends of the base plate section 81. This increases the likelihood that the outdoor wall sections 83 located at both longitudinal ends of the base plate section 81 will come into contact with the inner peripheral surface of the lower panel 211a of the upper frame 21, even if the shoji screen 3 warps in the middle of the longitudinal direction of the warp prevention fittings 8. This further prevents the shoji screen 3 from warping and twisting.

[0026] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0027] In the above embodiment, an example in which the fitting is applied to a horizontal sliding window has been described, but the fitting is not limited to this. The fitting is not limited to a horizontal sliding window, but may be a vertical sliding window, and the fitting can be applied to any fitting, such as a sliding door with a shoji screen that can slide horizontally, a hinged door that rotates around a rotation axis to open and close, or a fixed window with a shoji screen fixed to a frame.

[0028] In the above embodiment, the warp prevention fittings 8 are provided on the upper frame 31 of the shoji screen 3, but this is not limiting. The warp prevention fittings 8 may also be provided on the vertical frame of the shoji screen.

[0029] In the above embodiment, the warp prevention fitting 8 is provided with an indoor side wall 82 that stands from the end of the indoor side X2 of the base plate 81 toward the upper frame 21, and a pair of outdoor side wall 83 (wall) that are provided at both longitudinal ends of the base plate 81 and stand from the outdoor side X1 of the base plate 81, but this is not limiting. The warp prevention fitting 8 does not necessarily have to be provided with an indoor side wall 82.

[0030] In the above embodiment, the warp prevention metal fittings 8 are formed in a long shape, but this is not limited to this. The warp prevention metal fittings 8 may be formed in pieces that are provided on part of the outer periphery of the shoji screen 3. Multiple piece-shaped warp prevention metal fittings 8 may be provided intermittently on the outer periphery of the shoji screen 3.

[0031] In the above embodiment, the outdoor wall portion 83 of the warp prevention fitting 8 is provided at both longitudinal ends of the base plate portion 81, but this is not limiting. For example, the outdoor wall portion 83 may be provided midway along the longitudinal direction of the base plate portion 81, or may be provided only at one end.

[0032] In the above embodiment, the outdoor wall portion 83 is formed to extend in the indoor / outdoor direction (the view direction), but is not limited to this. The outdoor wall portion 83 does not have to extend in the indoor / outdoor direction (the view direction). [Explanation of symbols]
