に関するものである。The present invention relates to a metal fitting used for construction, wherein a driving engagement portion having a pot-shaped cross section provided at one end of the metal fitting is driven into a ridge of a sash frame to fix the metal fitting to the ridge. The present invention relates to an improvement in a grid stopper, such that a surface grid is fixedly held on a mounting portion of the bracket.

た。2. Description of the Related Art Conventionally, a grid fastener of this type has a flat occlusal edge with no work at this portion (Japanese Utility Model Laid-Open No. 56-114295), and a sash frame having a rubber packing. In order to use it, a notch was provided at the edge of the occlusion (Japanese Utility Model Application Laid-Open No. 62-31693).

【発明が解決しようとする課題】咬合部の縁端が平坦

切欠片を有するものは、切欠片がサッシ枠突条を圧する
力の反力が咬合部を開く方向に働いて、咬合力を減少さ

た。In the case where the occlusal portion has a flat edge and has no work at this portion, the resistance to the external force in the opposite direction to the driving of the metal fitting (that is, the pull-out resistance) is weak, and it is easy to come off. There is a drawback, and the notch with a notch at the edge of the occlusion part reduces the occlusal force because the reaction force of the force that presses the sash frame ridge acts in the direction to open the occlusion part and reduces the occlusion force. Has the drawback that the holding power of the steel is reduced.

水平部側に突出させた。In order to eliminate these drawbacks, the front wall of the pot-shaped driving engagement portion of the lattice fitting is extended downward, and below the extension of the lower surface of the horizontal portion of the main body,
The extension of the front wall is folded back along the inner surface of the front wall to form a folded wall, the end of the folded wall reaches the lumen of the occlusal part, and the side end of the fold is attached to the inner surface of the rear wall of the occlusal part. From the extension of the horizontal part.

おいて、咬合力がそれだけ大きくなる。(1) Extend the front wall of the pot-shaped driving bite portion of the lattice fastener downward, and fold the extension of the front wall along the inner surface of the front wall below the extension of the lower surface of the horizontal portion of the main body. Since the side end of the folded portion protrudes toward the horizontal portion from an extension of the inner surface of the rear wall of the bite portion, when the metal fitting of the present invention is driven into the ridge of the sash frame, the metal fitting of the present invention is compared with the conventional metal fitting. As a result, the front wall of the occlusion portion is pushed open by an extra distance (d) between the extension line (YY) of the inner surface of the rear wall of the pot-shaped driving occlusion portion and the end of the folded portion. The occlusal force increases within the elastic limit of the metal material of the occlusal portion.

Will be located above the end of the folded wall. Therefore, when the metal fitting of the present invention is to be pulled upward, the end of the folded wall is always hooked to the jaw of the ridge head, and it is extremely difficult to pull out the metal fitting.

First, the opening (17) of the pot-shaped engaging portion (2) of the main body (1) is brought into contact with the head (15) of the ridge (6) of the sash frame (5), and the pot-shaped engaging portion (2) is placed. ), And the pot-shaped biting portion (2) is forcibly fitted to the ridge (6). When completely fitted, the head (15) of the ridge (6) enters above the end (10) of the folded wall (9) and the end (1) of the folded wall (9).
0) enters under the jaw (16) of the ridge (6) and comes into contact with the surface of the ridge (6). The state is as shown in FIG. Therefore, the following effects are obtained.

Is folded along the inner surface of the front wall (8), and the folded portion (1
Since the side end (14) of (3) projects from the extension (Y-Y) of the inner surface of the rear wall (7) of the occlusion part (2) toward the horizontal part (3), the pot-shaped driving occlusion part is formed. When (2) is externally fitted to the ridge (6) of the sash frame (5) and driven into the sash frame (5), the front wall (8) of the occlusal portion (2) uses a conventional fitting (for example, the fitting shown in FIG. 5). The distance (d) between the extension (Y-Y) of the inner surface of the rear wall (7) and the side end (14) of the folded portion (13), Only then, the front wall (8) is pushed open. Therefore, the occlusal force increases within the elastic limit of the driving occlusion (2). Therefore, a metal fitting having stronger mounting strength can be supplied with the same size metal fitting.

で、咬合力には殆ど影響はない。(B) In the metal fitting of the present invention, since the end (10) of the folded wall (9) of the front wall (8) enters the lumen (11) of the occlusion part (2), the metal fitting is sashed. When the ridge (6) of the frame (5) is driven, the head (15) of the ridge (6) goes deeper than the end (10) of the folded wall (9), and the end (10) of the folded wall (9). ) Is in contact with the surface of the ridge (6) below the jaw (16) of the ridge (6). Therefore,
If the metal fitting is to be pulled upward, it is extremely difficult to pull out the metal fitting because the end (10) of the folded wall (9) always catches on the jaw (16) of the ridge (6). Therefore, it is extremely difficult to remove metal fittings from the outside illegally.
Great security. When the metal fittings are driven, even if the end (10) of the folded wall (9) slightly presses the surface of the ridge (6) of the sash frame (5), the pressing force is the action of the occlusal force. Point (that is, the side end (1
4) Since it acts at a point farther above, the biting force is only slightly reduced by this pressing force and has little effect on the biting force.
