"German patent specification DE 195 05 707 relates to a collapsible umbrella, the covering of which is supported by star-shaped canopy rods, which are arranged around the umbrella shaft. The canopy rods are articulated in a pivotable manner on a crown, which can be displaced along the umbrella shaft and clamped to its upper end, and in the expanded state of the umbrella, they are supported by support rods, which are articulated to the canopy rods with one end and to a slide on the other end, with said slide also being capable of being displaced and locked along the umbrella shaft. The closing and shortening of the umbrella takes place by collapsing the canopy rods above the crown and by inserting the umbrella shaft between the collapsed canopy rods. The characteristic of the arrangement lies in that the canopy rods and the support rods are collapsed away from the user."

特許文献２は、折畳み傘に関し、傘地は中棒周囲に配置される星形状の親骨により支持される。親骨は、中棒に沿って移動可能かつ中棒上端に固定される上ろくろ上に枢動可能に間接接合され、また、傘が開いた状態において受骨により支持され、受骨は一方端において親骨に、他方端において下ろくろに間接接合されるが、下ろくろもまた中棒に沿って移動及び固定可能である。傘の折畳みは、親骨を上ろくろ上方で折畳み、中棒を折畳んだ親骨間に挿入することにより行われる。本装置の特徴は、親骨及び受骨が使用者に対向する方向に折畳まれることである。
