Description

本発明は、開口を形成する枠体と、開口を閉塞可能に支持された障子と、を有する建具に関する。 The present invention relates to a fitting having a frame for forming an opening and a shoji for which the opening can be closed.

建具の中には、例えば、金属製室外側枠材および断熱材製室内側枠材を有する断熱窓枠と、金属製室外側框材および断熱材製室内側框材を有する断熱框を備えた断熱障子と、を有する断熱性を備えた建具がある（例えば、特許文献１参照)。この建具は、障子を閉塞状態に保つためのラッチ機構を構成する金属製のラッチ受けが、金属製室外側枠材に固着された裏板に断熱材製室内側枠材を挟んでねじ止めされている。このとき、ラッチ受けと裏板との間には断熱材製室内側枠材が介在されているので、火炎等により断熱材製室内側枠材が溶融した際に、ラッチ受けがガタつき、障子の閉塞状態が保たれない虞がある。このため、火炎等に晒されてもラッチ受けがガタつかないように、裏板から突出してラッチ受けに当接するヒレ片やバーリング孔を形成する、或いは、ラッチ受けと裏板との間に筒体を介在させてねじ止めしている。 Among the fittings, for example, a heat insulating window frame having a metal outdoor frame material and a heat insulating material indoor side frame material, and a heat insulating frame having a metal outdoor side frame material and a heat insulating material indoor side frame material were provided. There is a heat-insulating sash and a fitting having a heat-insulating property (see, for example, Patent Document 1). In this fitting, the metal latch receiver that constitutes the latch mechanism for keeping the shoji in a closed state is screwed with the heat insulating material indoor side frame material sandwiched between the back plates fixed to the metal outdoor side frame material. ing. At this time, since the heat insulating material indoor side frame material is interposed between the latch receiver and the back plate, when the heat insulating material indoor side frame material is melted by a flame or the like, the latch receiver rattles and the shoji is used. There is a risk that the blocked state will not be maintained. Therefore, to prevent the latch receiver from rattling even when exposed to flames or the like, a fin piece or a burring hole that protrudes from the back plate and comes into contact with the latch receiver is formed, or a cylinder is formed between the latch receiver and the back plate. It is screwed with the body in between.

本実施形態の建具１によれば、障子２が開口１０ａを閉塞した状態を維持可能なラッチ機構４１を合成樹脂製の枠体１０に固定する連結部材６は、金属製の枠補強材５に固定されている金属製のねじ５４の頭部５４ａに下面当接板部６０ａが当接されているので、火炎等に晒されて枠体１０の下面部１１３ｂが溶融したとしても、下面当接板部６０ａが枠補強材５を固定されている金属製のねじ５４に当接している状態が保たれる。このため、枠体１０が溶融したとしても、枠補強材５に固定されたラッチ機構４１にがたつきが生じることはない。このため、たとえ、火炎に晒されたとしても、障子２により開口１０ａが閉塞されている状態を維持することが可能である。 According to the fitting 1 of the present embodiment, the connecting member 6 for fixing the latch mechanism 41 capable of maintaining the state in which the obstacle 2 closes the opening 10a to the synthetic resin frame 10 is a metal frame reinforcing material 5. Since the lower surface contact plate portion 60a is in contact with the head 54a of the fixed metal screw 54, even if the lower surface portion 113b of the frame body 10 is melted by being exposed to a flame or the like, the lower surface contact is made. The state in which the plate portion 60a is in contact with the metal screw 54 to which the frame reinforcing member 5 is fixed is maintained. Therefore, even if the frame body 10 is melted, the latch mechanism 41 fixed to the frame reinforcing member 5 does not rattle. Therefore, even if it is exposed to a flame, it is possible to maintain the state in which the opening 10a is blocked by the shoji 2.

また、下面当接板部６０ａが当接される皿ねじ５４は、枠補強材５を上枠１１に固定するための皿ねじ５４なので、ラッチ機構４１が設けられていなくとも必ず用いられる。このため、必ず設けられる皿ねじ５４を下面当接板部６０ａが当接される位置に配置するだけで、火炎に晒されたとしても、障子２により開口１０ａが閉塞されている状態を維持することが可能な構成を備えた建具１を実現することが可能である。このため、火炎等に晒されても障子２が閉塞された状態を維持する構造を、コストを抑えつつも容易に備えることが可能な建具１を提供することが可能である。 Further, since the countersunk screw 54 to which the lower surface contact plate portion 60a is in contact is the countersunk screw 54 for fixing the frame reinforcing material 5 to the upper frame 11, it is always used even if the latch mechanism 41 is not provided. Therefore, by simply arranging the countersunk screw 54 that is always provided at the position where the lower surface contact plate portion 60a is in contact with each other, the opening 10a is maintained in a state of being closed by the shoji 2 even if it is exposed to a flame. It is possible to realize the fitting 1 having a possible configuration. Therefore, it is possible to provide a fitting 1 capable of easily providing a structure in which the shoji 2 is maintained in a closed state even when exposed to a flame or the like while suppressing the cost.

It is fixed to 6 without loosening. Further, since the lower surface contact plate portion 60a as the contact plate portion of the connecting member 6 is in contact with the head portion 54a of the metal screw 54, the latch mechanism 41 and the frame reinforcing material 5 are brought into contact with each other. Even if the fitting 1 having the structure in which the connecting member 6 is interposed is exposed to the flame, the latch bolt 41a is maintained in the state of being engaged with the receiving metal fitting 42, and the opening 10a is closed by the shoji 2.
