ところで、下枠の屋内側に樹脂製部材を配置して断熱性を向上させることがある。しかし、設計上の制約やデザイン性の観点から、下枠の屋内側に配置される樹脂製部材の見込方向の厚みを確保できない場合もある。このような場合において、金属製の下枠を屋外側と屋内側に分割し、樹脂製のブリッジによって屋外側と屋内側をカシメ加工で連結する方法が考えられる。しかし、屋内側と屋外側が分割される結果、屋内側から屋外側に排水を行うための排水経路が閉じられてしまうことになり、排水性能が低下してしまう。 By the way, a resin member may be arranged on the indoor side of the lower frame to improve the heat insulating property. However, from the viewpoint of design restrictions and designability, it may not be possible to secure the thickness of the resin member arranged on the indoor side of the lower frame in the expected direction. In such a case, a method is conceivable in which the metal lower frame is divided into an outdoor side and an indoor side, and the outdoor side and the indoor side are connected by caulking with a resin bridge. However, as a result of the indoor side and the outdoor side being divided, the drainage route for draining from the indoor side to the outdoor side is closed, and the drainage performance is deteriorated.

本発明は、建物又は建具の開口部に固定される下枠を備える建具において、見込方向の厚みを大きくすることなく断熱性の向上及び排水性を両立できる構成を提供することを目的とする。 It is an object of the present invention to provide a fitting having a lower frame fixed to an opening of a building or a fitting, in which both improvement of heat insulating property and drainage property can be achieved without increasing the thickness in the prospective direction.

A lower resin bridge (lower resin member) 670 that forms an intermediate space 602 together with an upper resin bridge 660 between the aluminum profile 710 and the outdoor side aluminum profile 610, and a hollow portion 601, an intermediate space 602 and a hollow portion 603. A drainage path 900 leading to an outlet 620 formed in the outdoor side aluminum profile 610 is provided.

これにより、上側樹脂ブリッジ６６０及び下側樹脂ブリッジ６７０によって断熱性を向上させつつ、開口部下枠５２に進入した水を屋内側に漏水させることなく、排水経路９００を通じて屋外に排出できる。本実施形態のように、屋内側の樹脂製部材である下額縁８２の厚みが薄い構造であっても、開口部下枠５２で十分な断熱性を確保できるので、構造やデザインに左右されることなく十分な断熱性能を発揮できるのである。即ち、本実施形態の構成によれば、高い断熱性及び排水性の両立を実現できるのである。 As a result, the water that has entered the opening lower frame 52 can be discharged to the outside through the drainage path 900 without leaking to the indoor side while improving the heat insulating property by the upper resin bridge 660 and the lower resin bridge 670. Even if the lower frame 82, which is a resin member on the indoor side, has a thin structure as in the present embodiment, the opening lower frame 52 can secure sufficient heat insulating properties, so that it depends on the structure and design. It is possible to demonstrate sufficient heat insulation performance. That is, according to the configuration of the present embodiment, both high heat insulation and drainage can be realized.

Therefore, in the present embodiment, the lower resin bridge 670 is not required to have water resistance, and the manufacturability can be improved. Further, since the lower resin bridge 670 is located below the indoor extension piece 630, the drainage path 900 is not hindered by the thickness even if the thickness is sufficient to withstand the caulking pressure during molding. It is possible to achieve both heat insulation and drainage without complicated processing.

また、本実施形態では、屋内側延出片６３０の先端が上方に立ち上がる形状である。 Further, in the present embodiment, the tip of the indoor extension piece 630 rises upward.

これにより、屋内側延出片６３０の先端が上方に立ち上がっているので、屋内側延出片６３０の上面に落下した水の屋外側への移動を規制することができ、下側樹脂ブリッジ６７０に水が触れる事態をより確実に防止することができる。
る。 As a result, since the tip of the indoor extension piece 630 rises upward, it is possible to restrict the movement of the water that has fallen on the upper surface of the indoor extension piece 630 to the outdoor side, and the lower resin bridge 670 can be used. It is possible to more reliably prevent the situation where water comes into contact.
