A large number of parent bones (10) and receiving bones (34) shown in FIG. 3 are radially attached to the upper and lower rokuro (8) and (6). Umbrella cloth (not shown) is stretched.

次に、本実施形態の作用について説明する。
中棒（２）を伸ばし、該中棒（２）を軸にして下ロクロ（６）を上方にスライドさせると、受骨（２２）により、リブ（１０ａ）が押し上げられ、リブ（１０ａ）は、図３に示すように、上ロクロ（８） を支点として、中棒（２）との角度（α）が開く方向に揺動する。 Next, the operation of this embodiment will be described.
When the middle rod (2) is stretched and the lower rocker (6) is slid upward with the middle rod (2) as an axis, the rib (10a) is pushed up by the rib (22), and the rib (10a) As shown in FIG. 3, the upper rocker (8) swings in the direction in which the angle (α) with the center rod (2) opens with the fulcrum as the fulcrum.

リブ（１０ａ）の揺動に伴って、リンク骨（２２）を構成要素とする四辺形リンク機構の作用により、リブ（１０ｂ）がリブ（１０ａ）に対して、これとの角度（β）が開く方向に揺動する。
更に、リブ（１０ｂ）のリブ（１０ａ）に対する角度（β）の変化に伴って、第１連結軸（３６）を構成要素とする四辺形リンク機構（４４）の作用により、リブ（１０ｃ）が、リブ（１０ｂ）に対して、これとの角度（γ）が開く方向に揺動する。 As the rib (10a) swings, the rib (10b) has an angle (β) with respect to the rib (10a) due to the action of the quadrilateral link mechanism having the link bone (22) as a component. Swings in the opening direction.
Further, as the angle (β) of the rib (10b) with respect to the rib (10a) changes, the rib (10c) is moved by the action of the quadrilateral link mechanism (44) having the first connecting shaft (36) as a component. The rib (10b) swings in an opening direction with respect to the angle (γ).

更に、リブ（１０ｃ）のリブ（１０ｂ）に対する角度（γ）の変化に伴って、第２連結軸（４６）を構成要素とする四辺形リンク機構（５２）の作用により、連結具（１８）が、リブ（１０ｃ）に対して、これとの角度（θ）が開く方向に揺動する。下ロクロ（５）を中棒（２）の上端係止位置まで上昇させると、各リブ（１０ａ）（１０ｂ）（１０ｃ）（１０ｄ）は、一直線状となり、傘が開いた状態となる。   Further, as the angle (γ) of the rib (10c) with respect to the rib (10b) changes, the coupling (18) is caused by the action of the quadrilateral link mechanism (52) having the second connecting shaft (46) as a component. However, it oscillates in the direction in which the angle (θ) with respect to the rib (10c) opens. When the lower rocker (5) is raised to the upper end locking position of the middle rod (2), the ribs (10a) (10b) (10c) (10d) are in a straight line and the umbrella is opened.

該状態において、下ロクロ（６）は、はじき（図示省略）により、解除可能に中棒（２）に係止される。下ロクロ（６）の係止を解除し、下ロクロ（６）を中棒（２）に沿って、下方向にスライドさせると、上記した動作とは逆の動作によって、各リブ（１０ａ）（１０ｂ）（１０ｃ）（１０ｄ）が図１に示す如く折り畳まれる。このとき、リブ（１０ｃ）は、リブ（１０ｂ）の、図４中、左側面に枢支（１６）されているため、リブ（１０ｂ）の側面側に隣接配置され、互いに折り畳み洋傘の半径方向に重なることがなく、各リブ（１０ａ）（１０ｂ）（１０ｃ）（１０ｄ）は、コンパクトに折り畳まれる。更に、中棒（２）を縮小し、傘の折り畳みが完了する。なお、リブ（１０ｃ）は、リブ（１０ｂ）の、図４中、右側面に枢支（１６）しても良い。   In this state, the lower rocker (6) is releasably locked to the center rod (2) by repelling (not shown). When the lower rocker (6) is unlocked and the lower rocker (6) is slid downward along the center rod (2), the ribs (10a) ( 10b), 10c, and 10d are folded as shown in FIG. At this time, the rib (10c) is pivotally supported (16) on the left side surface of the rib (10b) in FIG. The ribs (10a), (10b), (10c), and (10d) are folded compactly. Further, the middle rod (2) is reduced, and the folding of the umbrella is completed. The rib (10c) may be pivotally supported (16) on the right side in FIG. 4 of the rib (10b).
