PROBLEM TO BE SOLVED: To provide an ottoman which is lightweight, in which an expansion link is gradually rotated, and a footrest member can be surely expanded to a full expansion position, and which can be easily stored by slightly pushing the footrest member.SOLUTION: An ottoman 1 comprises: an expansion link 10 which is expanded by a predetermined locus; lock means 8 for regulating rotation of the expansion link 10; and an expansion spring 5 for expanding the expansion link 10 and spring attachment bars 33A, 33C, and the ottoman is pulled from a storage position and is used. The ottoman 1 further comprises: a torque brake 6; an expansion regulation contact part 25A; an expansion regulation contacted part 25B; a storage regulation contact part 35A; and a storage regulation contacted part. The expansion link 10 has a specific rotation support shaft in which, a rotation range of two links for sandwiching a rotation support shaft 31C is almost 90°, and an angle θ formed by a line segment connecting one end of the expansion spring 5 and the rotation support shaft 31C, and a line segment connecting one end and the other end of the expansion spring 5, becomes almost 90° at a full expansion position, and becomes almost 0° at a storage position.SELECTED DRAWING: Figure 3
【課題】展開リンクがゆっくりと回動してフットレスト部材が全展開位置まで確実に展開でき、フットレスト部材を軽く押すことで楽に格納できる、軽量化されたオットマンを提供する。【解決手段】オットマン1は、所定の軌跡で展開する展開リンク10と、展開リンク10の回動を規制するロック手段8と、展開リンク10を展開させる展開バネ5及びバネ取付バー33A、33Cとを備え、格納位置から引き出されて使用される。オットマン1は、さらにトルクブレーキ6、展開規制当接部25A、展開規制被当接部25B、格納規制当接部35A及び格納規制被当接部を備える。展開リンク10には、回動支軸31Cを挟む2本のリンクの回動範囲が略90°である特定回動支軸が設けられ、展開バネ5の一端と回動支軸31Cとを結ぶ線分と、展開バネ5の一端と他端とを結ぶ線分とがなす角θが、全展開位置で略90°、格納位置で略0°となる。【選択図】図3
