FLUSH BOLT RECEIVER AND FLUSH BOLT PROVIDED WITH RECEIVER

PROBLEM TO BE SOLVED: To provide a flush bolt receiver and a flush bolt provided with the receiver that allow a drop bar of the flush bolt to be fitted smoothly and prevent entry of a waste, dust, sand, etc., even in a case of erroneous fitting between the drop bar on a flush bolt body and the receiver.SOLUTION: A flush bolt includes: an external cylinder member of a bottomed cylindrical form fit into a recess formed on a surface of installation; and an inner cylinder member inserted and fit coaxially and rotatably in the external cylinder member, the internal cylinder member having a through-hole into which a tip of a drop bar of a flush bolt body may be inserted, at a location deviating from the axis of the external cylinder member. The inner cylinder member has, in the through-hole, a cover that closes an opening on an upper side of the through-hole, an elastic body that energizes the cover toward the opening on the upper side of the through-hole, and support means that comes in contact with a lower edge of the elastic body for fixing and supporting the elastic body.SELECTED DRAWING: Figure 1 【課題】フランス落し本体の落し棒と受具の取付け誤差があっても、フランス落しの落し棒をスムーズに嵌めることができると共に、ゴミ、埃、砂等の侵入を防ぐことができるフランス落し受具及びこの受具を備えたフランス落しを提供する。【解決手段】フランス落し受具は、被設置面に設けられた凹部に嵌入される有底筒状の外筒部材と、軸から偏心した位置にフランス落し本体の落し棒の先端が挿入可能な貫通穴が設けられ、外筒部材に同軸にかつ回動可能に挿嵌される内筒部材とを備えている。内筒部材は、貫通穴内に、この貫通穴の上側開口部を閉塞する蓋と、蓋を貫通穴の上側開口部へ向けて付勢する弾性体と、弾性体の下端に当接して固定支持する支持手段とを有している。【選択図】図１
