The lowering prevention member 3 is provided so that the glass panel 2 does not lower even if the setting block 16 melts and softens in the event of a fire, and is formed of an extruded aluminum alloy profile, as shown in FIG. It also has a hollow main body portion 17 having a rectangular cross section, and an L-shaped cross-sectional fall prevention portion 5 extending from the upper part of the indoor side wall of the main body portion 17 toward the indoor side. The upper surface of the main body 17 is close to the lower end of the glass panel 2, and the fall prevention portion 5 is provided along the indoor side of the receiving portion 10b of the backup material 11. The setting block 16 and the lowering prevention member 3 are adhered to the bottom wall 19 of the panel mounting groove 4 with double-sided tape.

As shown in FIG. 1, the lower frame 1 has a recess 18 having an open outdoor side at a position below the panel mounting groove 4. The bottom wall 19 of the panel mounting groove 4 is provided with a drain hole 20 at a position within about 100 mm from both left and right ends.
A crush prevention component 21 is held in the recess 18, and the crush prevention component 21 is provided over the entire length of the lower frame 1 in the longitudinal direction, and is located below the setting block 16 and the drop prevention member 3. The crush prevention component 21 is formed of an extruded aluminum alloy, and has a vertical outer wall 22 and an inner wall 23, and a side wall 24 connecting them. The outer wall 22 is provided on the outdoor side of the recess 18 over the upper wall (bottom wall of the panel mounting groove) 19 and the lower wall 25 of the recess 18. The inner wall 23 is in contact with the outdoor side of the upright wall 26 of the recess 18. The side wall 24 is provided with a drain hole 27 at a position displaced in the left-right direction from the drain hole 20 of the bottom wall 19 of the panel mounting groove 4, for example, at a position about 50 mm inside from both left and right ends, and the outer wall 22 is provided with a drain hole 27.

Therefore, the rainwater that has entered the panel mounting groove 4 is drained from the drain hole 20 of the bottom wall 19 of the panel mounting groove 4 and the drain hole 27 of the side wall 24 of the crush prevention component 21 as shown by an arrow 29 in FIG. And drained to the outside through the notch 28 of the outer wall 22. In the crush prevention component 21, the upper end of the outer wall 22 is locked to the hanging piece 30 formed at the outdoor end of the upper wall (bottom wall of the panel mounting groove) 19 of the recess 18, and as shown in FIG. By being sandwiched between the left and right vertical frames 8 and 8 from both sides, it is held so as not to move in the recess 18.

FIG. 5 shows the state of one part of the lower frame at the time of fire. When a fire breaks out, as shown in the figure, the heated foaming material 14 attached to the indoor side of the outdoor wall 12 of the panel mounting groove 4 foams due to the heat of the fire and expands toward the indoor side to prevent it from falling. Press member 3. The fall prevention member 3 tries to fall by being pushed by the expanded heated foam material 14, but the fall prevention member 3 is locked inside the upper wall 31 of the lower frame 1 so that the fall prevention member 3 falls. Can be regulated. Therefore, even in the event of a fire, the state in which the glass panel 2 is prevented from falling is maintained by the lowering prevention member 3, and it is possible to prevent the glass panel 2 from lowering and opening a through hole between the upper end of the glass panel 2 and the upper frame 7. .. In FIG. 5, the heating foam material 15 on the indoor side in the panel mounting groove 4 is omitted in order to make it easier to see the state of the lowering prevention member 3.
Further, since this fitting has a recess 18 whose outdoor side is open at a position below the panel mounting groove 4 of the lower frame 1, the standing wall 26 of the recess 18 is located on the indoor side from directly below the glass panel 2. When the strength of the lower frame 1 is reduced due to heating during a fire, the recess 18 is crushed by the weight of the glass panel 2 and the lower frame 1 is deformed in a shape that twists to the outside of the room, and the glass panel 2 is accompanied by the deformation. There is a risk that the through hole will open on the upper frame 7 side. It is possible to prevent the frame 1 from being deformed and to prevent the glass panel 2 from being lowered to form a through hole.

As described above, in the present fitting, the lowering prevention member 3 is provided in the panel mounting groove 4 of the panel support member (lower frame 1), and the upper surface of the lowering prevention member 3 is in contact with the lower end of the glass panel 2. The panel support member 1 is deformed or foamed in the event of a fire because the panel support member 1 or the lowering prevention member 3 is close to each other and has a fall prevention portion 5 for restricting the fall of the lowering prevention member 3 on one or both of the panel support members 1. Even if it is pushed by the heated foam material 14, it is possible to prevent the lowering prevention member 3 from falling down and prevent the through hole from opening.
The panel support member 1 or the lowering prevention member 3 is in contact with or engaged with the other party (in the embodiment, the falling prevention portion 5 of the lowering prevention member 3 is engaged with the lower frame 1). The fall prevention member 3 can be reliably prevented from falling.

This fitting has a panel mounting groove 4 in the lower frame 1 and a recess 18 having an open outdoor side at a position below the panel mounting groove 4, and a panel receiving component (setting block 16 and a lowering prevention member) in the panel mounting groove 4. 3) is provided, the crush prevention component 21 is held in the recess 18, and the crush prevention component 21 is located below the panel receiving parts 16 and 3, so that the crush prevention component 21 is a glass panel 2. Since the weight of the glass panel 2 is received, it is possible to prevent the recess 18 from being crushed and the lower frame 1 being deformed in a shape that bows to the outside of the room in the event of a fire. ..
Further, since the fitting has a drainage hole 20 that leads to the recess 18 in the bottom wall 19 of the panel mounting groove 4, rainwater that has entered the panel mounting groove 4 can be drained to the outside.
Since the crush prevention component 21 has an outer wall 22 provided over the upper wall (bottom wall of the panel mounting groove) 19 and the lower wall 25 on the outdoor side of the recess 18, the recess 18 is deformed so as to be crushed. Can be reliably prevented.
Further, since the panel receiving component (lowering prevention member 3) of this fitting is made of metal, it is possible to prevent the glass panel 2 from being lowered in the panel mounting groove 4 in the event of a fire.

6 and 7 show a second embodiment of the fitting of the present invention. In the fitting of the present embodiment, the lowering prevention members 3 are provided in the panel mounting groove 4 of the lower frame at three locations, the left side, the center, and the right side, and the left and right lowering prevention members 3 are EPDM sheets on the upper surface of the main body. By pasting 32, it is used as a setting block.
Similar to the first embodiment, the fitting of the present embodiment can prevent the lowering prevention member 3 from falling, and can prevent the glass panel 2 from lowering to form a through hole. The structure is simplified because there is no need to provide a separate setting block.

FIGS. 8 and 9 show comparative examples of the fittings of the present invention. The lowering prevention member 3 is a square pipe shape having no fall prevention portion 5. The crush prevention component 21 is piece-shaped and is provided only directly under the lowering prevention member 3, and is fixed to the lower frame 1 with screws 33.
The fittings of this comparative example can also prevent the lower frame 1 from being deformed in the event of a fire and prevent the glass panel 2 from lowering and opening the through hole. It is not necessary to form a drain hole or a notch in the crush prevention component 21.

FIG. 10 shows another embodiment of the crush prevention component 21. The crush prevention component 21 of FIG. 10A has a hollow shape having an outer wall 22, an inner wall 23, an upper wall 34, and a lower wall 35. The crush prevention component 21 of FIG. 10B has a U-shaped cross section in which the lower side having the outer wall 22, the inner wall 23, and the upper wall 34 is open. The crush prevention component 21 of FIG. 10 (c) has a U-shaped cross section having an outer wall 22, an inner wall 23, and a lower wall 35 with an open upper side.
These crush prevention parts 21 have an effect of preventing deformation of the lower frame 1 as in the case of the H-shaped cross section shown in FIG. 1 and the like. Since the crush prevention component 21 having an H-shaped cross section has a small contact area with the lower frame 1, it is easy to insert it when sliding it into the recess 18 from the edge.

The present invention is not limited to the embodiments described above. The cross-sectional shape and material of the panel support member are arbitrary. The fall prevention portion may also be provided so as to abut or engage with the lowering prevention member from the panel support member. Further, it is also possible to provide a fall prevention portion on both the panel support member and the lowering prevention member. The mounting position and number of the lowering prevention members are not particularly limited. The crush prevention parts can be omitted. The panel support member may be a lower frame. The material and structure of the panel do not matter. The present invention can be applied not only to a fitting window but also to any fitting for mounting a panel in a panel mounting groove.
