As shown in FIG. 2, at the upper end of the lattice 6, upper mounting structures 10 are provided at three locations, for example, the right side, the left side, and the substantially central portion when the lattice 6 is viewed from the front.

The upper mounting structure 10 in the mounting structure of the screen lattice 6 will be described with reference to FIGS. 3 to 5 and 7 to 9. FIG. The upper mounting structure 10 shown in FIGS. 3 to 5 is located on the left side of the lattice 6 when viewed from the front. Components and members constituting the upper mounting structure 10, except for the first resin screw 60 and the second resin screw 69, are made of a heat-resistant metal material (for example, stainless steel).

The upper mounting structure 10 is provided at the upper end of the face lattice 6 . The upper mounting structure 10 is provided for mounting the face lattice 6 to the sash upper frame 21 of the sash 2 . The upper mounting structure 10 has a first upper engaging member 40 , a second upper engaging member 50 and a first resin screw 60 . The first upper engaging member 40 engages with the screen lattice upper engaging portion 36 provided on the screen lattice upper frame 31 of the screen lattice 6 . The second upper engaging member 50 engages with the sash upper engaging portion 26 provided on the sash upper frame 21 of the sash 2 . The first resin screw 60 functions as a first resin member that forms a connection fixation between the first upper engaging member 40 , the lattice upper engaging portion 36 and the second upper engaging member 50 . This allows easy and secure mounting.

As shown in FIG. 7 , the first upper engaging member 40 is a plate-like body bent in an L shape when viewed from above, and has a first base portion 41 and a first bent portion 43 . The first base portion 41 extends vertically and horizontally. For example, three screw holes 45 are formed side by side in the longitudinal direction in the first base portion 41 . The three screw holes 45 in the first upper engaging member 40 correspond to the three insertion holes 65 (illustrated in FIG. 12) in the surface grating upper engaging portion 36 . The first bent portion 43 extends in the vertical direction and the front-rear direction. For example, one hooking hole 48 is formed in the first bent portion 43 . The first upper engaging member 40 is housed in the housing portion 39 . The accommodating portion 39 is a space formed at the upper end portion of the screen lattice upper frame 31 and defined by the screen lattice upper engaging portion 36 .

As shown in FIG. 8, the second upper engaging member 50 is a plate-like body bent like a crank when viewed from the side, and includes a second base portion 51, a second bent portion 52, and a second engaging member. a portion 53; The second base 51 extends vertically and horizontally. In the second base portion 51, for example, two penetrating mounting holes 55 are formed side by side in the longitudinal direction. The mounting hole 55 is, for example, an elongated hole. The two mounting holes 55 in the second upper engaging member 50 correspond to the two screw holes located on the spring hooking member 66 side among the three screw holes 45 in the first upper engaging member 40 . The two mounting holes 55 are used for connecting and fixing with the first resin screw 60 . Of the three screw holes 45 in the first upper engaging member 40, one screw hole located on the opposite side of the spring hooking member 66 is used for temporary fixing by a second resin screw 69, which will be described later. The second bend 52 extends horizontally. The second engaging portion 53 extends vertically and horizontally so as to protrude toward the side facing the sash 2, for example.

The first resin screw 60 serving as the first resin member 60 is a male screw and has a threaded portion 61 . The threaded portion 61 of the first resin screw 60 is inserted through the mounting hole 55 of the second upper engaging member 50 and the insertion hole 65 (shown in FIG. 12) of the upper engaging portion 36, and It is screwed into the screw hole 45 of the engaging member 40 . As shown in FIG. 5, the first upper engaging member 40 and the second upper engaging member 50 hold the lattice upper engaging portion 36 between them, and then the first resin screw 60 is tightened to obtain the second upper engaging member. The member 50 is connected and fixed to the screen lattice upper engaging portion 36 provided on the screen lattice upper frame 31 of the screen lattice 6 . When the second upper engaging member 50 is connected and fixed to the surface lattice upper engaging portion 36 by the first resin screw 60, the second engaging portion 53 is positioned above the first upper engaging member 40, that is, in the plane direction. It protrudes above the lattice upper frame 31 . The second engaging portion 53 of the second upper engaging member 50 is configured to engage with the sash upper engaging portion 26 of the sash upper frame 21 . When the first resin screw 60 softens and melts, the engagement between the second engaging portion 53 and the upper sash engaging portion 26 is released, so that the lattice 6 becomes movable, that is, rotatable. .

The first resin screw 60 is made of thermoplastic resin. The thermoplastic resin is polycarbonate, for example, and has a melting point of 180° C. or higher and 220° C. or lower, for example. Polycarbonate has moderate mechanical strength and melting point, so it can satisfy the requirements of installation and fire resistance.

Since the first resin screw 60 is made of a thermoplastic resin, the first resin screw 60 is softened and melted by the heat from the inside of the building when a fire breaks out inside the building having the sash 1 with the lattice. . As a result, the engagement of the second upper engaging member 50 with the sash upper engaging portion 26 is released, so that the screen lattice 6 can move away from the sash 2, that is, can rotate. By moving, ie, rotating, the screen lattice 6 away from the sash 2, the closed space by the screen lattice 6 is opened, and the heat inside the building can be released to the outside. Even with the sash 1 with a face grille, the sash 2 can be prevented from being adversely affected by fire prevention, and the flame shielding performance of the sash 2 can be maintained. Details will be described later.

As shown in FIGS. 14-16, the upper mounting structure 10 further includes a biasing member 62. As shown in FIGS.

The biasing member 62 is, for example, an extension coil spring 62 that moves the first upper engaging member 40 in the left-right direction along the lattice upper engaging portion 36 in a biased state. As a result, the upper mounting structure 10 can be arranged at the right upper end portion or the left upper end portion of the screen lattice 6, and the engagement of the upper mounting structure 10 is stabilized. A hook 64 on one side of the tension coil spring 62 is hooked on the hook hole 48 of the first upper engaging member 40 . A hook 64 on the other side of the tension coil spring 62 is hooked on a hook portion 68 of a spring hook member 66 attached to the screen upper frame 31 . The tension coil spring 62 is held between the spring hooking member 66 and the first upper engaging member 40 in a state of being stretched longer than its natural length. The tension coil spring 62 urges the first upper engaging member 40 in a direction to approach the spring hooking member 66 .

When the product is shipped, the first upper engaging member 40 is temporarily fixed to the face lattice upper engaging portion 36 by the second resin screw 69 in order to maintain the stretched state of the tension coil spring 62 . That is, before forming the connection and fixation between the first upper engaging member 40, the second upper engaging member 50, and the lattice upper engaging portion 36, the first upper engaging member 40 and the lattice upper engaging portion 36 are separated. The joint portion 36 is temporarily fixed by the second resin screw 69 . This allows easy and secure mounting. In other words, the second resin screw 69 is used for temporary fixing of the first upper engaging member 40 and functions as a second resin member. As a result, as shown in FIG. 16 , the engaging operation of engaging the second upper engaging member 50 with the sash upper engaging portion 26 using the first resin screw 60 can be easily performed on site.

As shown in FIGS. 4, 5 and 16, the first resin screw 60 is used to connect the first upper engaging member 40, the second upper engaging member 50, and the lattice upper engaging portion 36. A joint fixation is formed. With the first upper engaging member 40 temporarily fixed to the lattice upper engaging portion 36 by the second resin screw 69, the second upper engaging member 50 is attached to the sash upper engaging portion 26 from the sash 2 side. Then, the second upper engaging member 50 is fixed to the first upper engaging member 40 with the first resin screw 60 . As a result, the upper attachment structure 10 for attaching the surface lattice 6 to the sash upper frame 21 of the sash 2 is completed. Such an upper mounting structure 10 corresponds to the upper mounting structure 10 when the face grating 6 is in the closed position.

Therefore, the surface lattice 6 is attached to the sash upper frame 21 of the sash 2 by the upper attachment structure 10 . Further, according to the upper mounting structure 10, the first upper engaging member 40 and the second upper engaging member 50 are fixed to the lattice upper engaging portion 36, whereas the second upper engaging member 50 is fixed to the upper engaging portion 36. is engaged with the sash upper engaging portion 26, the upper mounting structure 10 can be arranged on the sash 1 with a lattice without damaging the sash 2. - 特許庁

A second resin screw 69 that functions as a second resin member is made of the same thermoplastic resin as the first resin screw 60 . The thermoplastic resin is polycarbonate, for example, and has a melting point of 180° C. or higher and 220° C. or lower, for example. Polycarbonate has moderate mechanical strength and melting point, so it can satisfy the requirements of installation and fire resistance.

Since the second resin screw 69 is made of the same thermoplastic resin as the first resin screw 60, when a fire breaks out inside the building having the sash 1 with the lattice, the heat from inside the building will cause the second resin screw to break. The screw 69 softens and melts. As a result, the temporary fixing of the first upper engaging member 40 to the face lattice upper engaging portion 36 is released. The tension coil spring 62 slides the first upper engaging member 40 along the lattice upper engaging portion 36 in the horizontal direction, thereby fusing the first resin screw 60 and the second resin screw 69 . As a result, the first resin screw 60 and the second resin screw 69 can be reliably fused.

17 and 18, the upper mounting structure 10 when the screen lattice 6 is in the open position will be described.

When a fire occurs, the first resin screw 60 and the second resin screw 69 are softened and melted by the heat of the fire. At this time, the tension coil spring 62 causes the first upper engaging member 40 to slide toward the spring hooking member 66 along the lattice upper engaging portion 36 . Due to the sliding movement of the first upper engaging member 40, the first resin screw 60 and the second resin screw 69 are reliably fused. Then, the second upper engaging member 50 is disengaged from the sash upper engaging portion 26 due to the melting of the first resin screw 60 . The disengaged second upper engaging member 50 drops.

Next, the lower mounting structure 15 in the mounting structure of the surface grating 6 will be described with reference to FIGS. 6 and 13. FIG. Components and members constituting the lower mounting structure 15 are made of a heat-resistant metal material (for example, stainless steel).

Thereby, the lower mounting structure 15 pivotally supports the surface grating 6 with respect to the sash 2 so as to be rotatable. The lower mounting structure 15 has a first pivot member 80 and a second pivot member 90 .

The first support member 80 is a plate-like body that is L-shaped when viewed from the side, and has a first support base portion 82 and a first support bending portion 83 . The first pivot base 82 extends in the front-rear direction and in the left-right direction. For example, two mounting holes (not shown) are formed side by side in the longitudinal direction in the first pivot base 82 . The first shaft support base 82 is fixed to the lattice lower frame 33 with a lower fixing screw 85 . The first bending portion 83 extends in the front-rear direction and the up-down direction. The first pivoting bending portion 83 has an oblong pivoting hole 86 .

The second support member 90 is a plate-like body bent in an L shape when viewed from above, and has a second support base portion 92 and a second support bending portion 94 . The second pivot base 92 extends in the front-rear direction and in the up-down direction. The second pivot base portion 92 abuts on the first bent pivot portion 83 . A pivot pin 87 is erected on the second pivot base portion 92 . The pivot pin 87 is inserted through the pivot hole 86 . The second pivotally bent portion 94 extends in the left-right direction and the up-down direction. The second pivotally bent portion 94 engages with the sash lower engaging portion 27 provided on the sash lateral frame 22 .

Therefore, the surface lattice 6 is rotatably supported with respect to the sash 2 by the lower mounting structure 15 . Further, according to the lower mounting structure 15 , the first axial support member 80 is fixed to the screen lattice lower frame 33 , while the second axial support member 90 is fixed to the sash lower engaging portion 27 of the sash horizontal frame 22 . , the lower mounting structure 15 can be arranged on the sash 1 with a screen without damaging the sash 2. - 特許庁

1, 10, 11 and 12, the rotation restricting structure 70 in the mounting structure of the screen lattice 6 will be described. In addition, the constituent elements and members constituting the rotation restricting structure 70 are made of a heat-resistant metal material (for example, stainless steel).

Rotation restricting structures 70 are provided at two locations on the upper left side and upper right side of the lattice 6 when viewed from the front. As a result, rotation of the screen lattice 6 is restricted and the screen lattice 6 is supported. The rotation restricting structure 70 has a sash-side bracket 71 , a sash-side arm 72 , and a lattice-side arm 75 .

The sash-side bracket 71 is a plate-like body bent in a U-shape, and is configured to engage with the side of the sash lateral frame 22 of the sash 2 on both sides. The sash side bracket 71 extends in the front-rear direction and the up-down direction. A sash-side link pin 74 is erected on the sash-side bracket 71 .

The sash-side arm 72 has an oblong sash-side link hole 73 on the sash 2 side. The sash-side link pin 74 is inserted through the sash-side link hole 73 . The sash-side arm 72 is rotatably supported with respect to the sash-side bracket 71 . The sash-side arm 72 has an upper link pin 78 on the face lattice 6 side.

The lattice-side arm 75 has an oblong lattice-side link hole 79 on the side of the sash 2 . The upper link pin 78 is inserted through the lattice-side link hole 79 . The grating-side arm 75 has an upper link hole on the grating 6 side. The lattice-side link pins 76 erected on the lattice horizontal frame 32 are inserted through the upper link holes. The lattice-side arm 75 is rotatably supported with respect to the lattice horizontal frame 32 .

Therefore, rotation of the surface grating 6 is restricted by the rotation restriction structure 70 . Further, according to the rotation control structure 70 , the lattice-side arm 75 is rotatably supported by the lattice-side frame 32 , while the sash-side bracket 71 is engaged with the side of the sash transverse frame 22 . Therefore, the rotation restricting structure 70 can be arranged on the sash 1 with a lattice without damaging the sash 2 .

Next, referring to FIGS. 14 to 21, the state change when the screen lattice 6 is rotated from the closed position to the open position due to the occurrence of fire will be described.

Figures 14 to 16 and 20 show the lattice 6 in the closed position. The first upper engaging member 40 is connected and fixed to the lattice upper engaging portion 36 and the second upper engaging member 50 by two first resin screws 60 . At the same time, the first upper engaging member 40 is temporarily fixed to the screen lattice upper engaging portion 36 by one second resin screw 69 . The first upper engaging member 40 is biased toward the spring hooking member 66 by the tension coil spring 62 in the extended state. Then, as shown in FIG. 16 , the upper mounting structure 10 engages the second engaging portion 53 of the second upper engaging member 50 with the sash upper engaging portion 26 of the sash upper frame 21 so that the lattice 6 is It is attached to the sash upper frame 21 of the sash 2 .

Figures 17 to 19 and 21 show the lattice 6 in the open position. When a fire breaks out inside a building having a sash 1 with a lattice, heat from inside the building softens and melts the first resin screw 60 and the second resin screw 69 . At this time, the biasing force of the tension coil spring 62 causes the first upper engaging member 40 to slide in the direction of the arrow shown in FIG. be done. By fusing the first resin screw 60 and the second resin screw 69, the first upper engaging member 40 and the second upper engaging member 50 are separated. The separated second upper engaging member 50 drops, for example, as shown in FIG.

By separating the first upper engaging member 40 and the second upper engaging member 50, the engagement of the second upper engaging member 50 with the sash upper engaging portion 26 is released. Then, as shown in FIG. 21 , the lower mounting structure 15 rotates the screen lattice 6 in a direction away from the sash 2 , but the rotation restriction structure 70 restricts the rotation of the screen lattice 6 . By rotating the screen lattice 6 away from the sash 2, the closed space by the screen lattice 6 is opened, and the heat inside the building can be released to the outside.

In this way, even with the sash 1 with the face lattice, it is possible to prevent the sash 2 from having an adverse effect on fire prevention, and the flame shielding performance of the sash 2 can be maintained. In addition, since the screen lattice 6 is locked to the sash 2 in an open state, the screen lattice 6 can be prevented from accidentally falling off from the sash 2. - 特許庁
