本考案はプラスチツク製傘骨に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a plastic umbrella rib.
従来の傘骨は、軽量化を意図して金属材により
断面Ｕ字状に形成し、これに先ダボ、中ダボ等の
抱き加工を施しているが、これにあつては工程が
多くて煩雑である欠点を有する。 Conventional umbrella ribs are made of metal and formed into a U-shaped cross section with the intention of reducing weight, and are then treated with dowels at the end, dowels at the center, etc., but this requires many steps and is complicated. It has certain drawbacks.
これに対し、本考案は親骨をプラスチツクによ

構造を一体成形し、且つ先骨の連結部における新
規な補強連結構造を提供するものである。 In contrast, in the present invention, by forming the main rib from plastic, the additional structure of the conventional umbrella rib can be integrally molded, and a new reinforcing connection structure is provided at the connecting part of the tip bone.
以下本考案の一実施例について図面と共に説明
すれば、Ａは親骨、Ｂは子骨、Ｃは受骨である。
親骨Ａは短繊維入りの強化プラスチツクにより形
成され、上ロクロに対する連結部A1、受骨に対
する連結部A2、子骨に対する連結部A3が一体に
形成されている。 An embodiment of the present invention will be described below with reference to the drawings, where A is the main bone, B is the coronal bone, and C is the bony bone.
The main bone A is made of reinforced plastic containing short fibers, and has a connecting part A 1 to the upper potter's wheel, a connecting part A 2 to the bridge, and a connecting part A 3 to the coronal bone integrally formed.
親骨Ａは、連結部A1，A2，A3を除いて断面Ｔ
字状に形成され、該形状により軽量化を達成しつ
つ、頭部１により横方向の屈曲力に対する強度を
もたせると共に脚部２により上下方向の屈曲力に
対する強度をもたせている。 The main rib A has a cross section T except for the connecting parts A 1 , A 2 , A 3
The head 1 provides strength against lateral bending force, and the leg portions 2 provide strength against vertical bending force, while reducing weight.
連結部A1，A2，A3にはそれぞれ連結孔３が形
成され、連結部A2には鳩目金具４により受骨Ｃ
が回動自在に連結され、連結部A3には子骨Ｂに
対する支持板部５が軸方向に延長して設けられ、
該支持板部５の上に設けられた軸受用突部６に対
して子骨Ｂの基端が鳩目金具４により回動自在に
連結される。 A connecting hole 3 is formed in each of the connecting parts A 1 , A 2 , and A 3 , and a bridge C is formed in the connecting part A 2 with an eyelet fitting 4 .
are rotatably connected, and the connecting part A3 is provided with a support plate part 5 extending in the axial direction for the coronal bone B.
The proximal end of the cotoid B is rotatably connected to a bearing protrusion 6 provided on the support plate portion 5 by an eyelet fitting 4.
子骨Ｂの基部には帯状の切り起し係止片７を有
する金属製管部材８が固着される。切り起し係止
片７は子骨Ｂの自由端方向側において係止部７′
を有し、開傘時において該係止片７が支持板部５
の係合孔９に進入し、該係止部７′が該係合孔９
の一側縁部９′に係合して該状態を安させる。 A metal tube member 8 having a band-shaped cut and raised locking piece 7 is fixed to the base of the coronal bone B. The cut-and-raised locking piece 7 has a locking portion 7' on the free end side of the coronal bone B.
When the umbrella is opened, the locking piece 7 is attached to the support plate portion 5.
The locking portion 7' enters the engagement hole 9 of the engagement hole 9.
This condition is relieved by engaging one side edge 9' of the.
本考案は上記した如くに、強化プラスチツクに

係止片を設け、開傘時において切り起し係止片の
子骨の自由端方向側に設けた係止部を該支持板部
の係合孔の一側縁部に係合させるものであるか
ら、子骨の横振れを防止しつつ開傘形状を安定し
て保持することができる。 As described above, the present invention consists of integrally molding the main bone together with a plurality of connecting parts for the potter's wheel etc. using reinforced plastic, providing an extended support plate part for the cochlear bone at the end of the main bone, and rotating the cochlear bone using a bearing part. A belt-shaped cut-and-raised locking piece is provided at the base of the cotyledon, and when the umbrella is opened, the locking portion provided on the side of the cut-and-raised locking piece toward the free end of the cotyledon is attached to the base of the cotyledon. Since it is engaged with one side edge of the engagement hole of the support plate part, it is possible to stably maintain the open umbrella shape while preventing the osseous bone from swinging laterally.
