LOCKING MECHANISM FOR HORIZONTAL PULL SHUTTER DEVICE AND HORIZONTAL PULL SHUTTER DEVICE
To provide means that prevents a shutter from being deformed and coming off as the door end side is pulled out even when affected by heat in the event of a fire and exhibits sufficient fire and smoke protection performance.SOLUTION: A horizontal pull shutter device, having a group of slats 2 located between guide rails, a stile located at the leading edge of the group of slats 2, an opening/closing device that winds and feeds the slat group, and a locking mechanism 5 at the door end side of the group of slats 2, in which locking mechanism 5 has a stile reinforcement member 51 that crosses between the guide rails to be located at the door end side of the group of slats 2, a first stopper receipt member 52 provided to the stile reinforcement member 51, a door stopper member 53 that is in opposition to the stile reinforcement member 51, a second receipt member 54 provided to the door stopper member 53, and a stopper 55 that lowers and comes into locking assemble with the first stopper receipt member 52 and the second stopper receipt member 54.SELECTED DRAWING: Figure 3
【課題】火災時に熱の影響を受けても、シャッターが変形して戸先側がひっぱられるように外れて抜けていくことを防ぎ、充分な防火性能及び防煙性能を発揮する手段を提供する。【解決手段】ガイドレール間に位置するスラット２群と、該スラット２群の先端側に位置するカマチ部材と、スラット群の巻き取り及び送り出しを行う開閉器と、スラット２群の戸先側にロック機構５とを有する、水平引シャッター装置であって、該ロック機構５が、前記ガイドレール間を横断し、スラット２群の戸先側に位置するカマチ補強部材５１と、該カマチ補強部材５１に取り付けた第１ストッパー受部材５２と、前記カマチ補強部材５１に対向する戸当部材５３と、該戸当部材５３に取り付けた第２ストッパー受部材５４と、前記第１ストッパー受部材５２及び前記第２ストッパー受部材５４に対して、下降して組み合うことでロックするストッパー５５を有する。【選択図】図３
