【発明の詳細な説明】
本発明は傘のプラスチツク製親骨に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plastic rib for an umbrella.
従来の傘の親骨は、剛性の強いピアノ線では重
くなるので、金属材を断面Ｕ字状に加工してころ
び変形を防止しつつその軽量化を達成している。
しかし、かかる親骨においては、先ダボ、中ダボ
等の抱き加工が必要であり、工数が多くて煩雑で
ある欠点を有する。 Since the main frame of a conventional umbrella is made of highly rigid piano wire, it is heavy, so the metal material is processed into a U-shaped cross section to prevent it from rolling and deformation while reducing its weight.
However, such ribs have the disadvantage that they require a lot of man-hours and are complicated, as it is necessary to process the end dowels, middle dowels, etc.
これに対し、本発明においては親骨をプラスチ
ツクにより製造することにより、従来の親骨にお

び変形防止のための補強構造を提供するものであ
る。 In contrast, in the present invention, by manufacturing the main rib from plastic, it is possible to integrally mold the additional structure on the conventional main rib, and in this case, it is possible to reduce the weight of the main rib and to prevent it from rolling and deforming. It provides a reinforcing structure.
以下本発明の一実施例について図面と共に説明
すれば、Ａは親骨、Ｂは親骨に付設される子骨、
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 rib, B is the child bone attached to the main bone,
C is a bone. The main bone A is made of reinforced plastic containing short fibers, and has a connection part A 1 to the upper potter's wheel, a connection part A 2 to the support bone, and a connection part A 3 to the coronal bone, which are 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剛性を
もたせると共に脚部２により上下方向の屈曲力に
対する剛性をもたせている。 The main rib A has a cross section T except for the connecting parts A 1 , A 2 , A 3
The head 1 provides rigidity against bending force in the lateral direction, and the leg portions 2 provide rigidity against bending force in the vertical direction, while achieving weight reduction due to the shape.
開傘時の傘に要求される従来からの形状を満足
するために、使用時において、親骨Ａは傘布の張
力により下方に湾曲する必要があり、閉傘時には
原形に復元しなければならない。 In order to satisfy the conventional shape required for an umbrella when opened, the main rib A needs to curve downward due to the tension of the umbrella cloth during use, and must return to its original shape when closed.
そこで、頭部１の上面には軸方向に延長する可
撓変形用溝１′が形成されている。 Therefore, a flexible deformation groove 1' extending in the axial direction is formed on the upper surface of the head 1.
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により同じく
強化プラスチツク製の受骨Ｃが回動自在に連結さ
れ、連結部A3には子骨Ｂに対するるプラスチツ
ク製連結具５がその軸受用突部６を介して鳩目金
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 portions A 1 , A 2 , and A 3 , and a strut C made of reinforced plastic is rotatably connected to the connecting portion A 2 through an eyelet fitting 4 . A plastic connector 5 to the coronal bone B is rotatably connected by an eyelet fitting 4 via its bearing protrusion 6.
親骨Ａにおいて、連結部A3の下面には軸方向
と交叉する方向の係合溝７が形成され、連結具５
の一側には開傘時において該係合溝７に嵌合する
係合突部８が形成される。 In the main rib A, an engagement groove 7 in a direction intersecting the axial direction is formed on the lower surface of the connecting part A 3 , and the connecting tool 5
An engagement protrusion 8 that fits into the engagement groove 7 when the umbrella is opened is formed on one side of the umbrella.
連結具５の他側には子骨Ｂの接続孔９が形成さ
れ、金属製又はプラスチツク製の子骨Ｂが接着剤
を用いて接続される。子骨Ｂがプラスチツク製の
場合には連結具５と一体成形される。 A connecting hole 9 for the cochlear bone B is formed on the other side of the connector 5, and the cochlear bone B made of metal or plastic is connected using an adhesive. When the femoral bone B is made of plastic, it is integrally molded with the connector 5.
連結具５は軸受用突部６を介して親骨Ａの端部
において連結部A3の上下方向に回動可能であり、
開傘時においては第２図の如くに親骨Ａの下方に
位置し、閉傘時においては上方に位置する。 The connecting tool 5 is rotatable in the vertical direction of the connecting part A 3 at the end of the main rib A via the bearing protrusion 6,
When the umbrella is opened, it is located below the main rib A, as shown in FIG. 2, and when the umbrella is closed, it is located above it.
本発明は上記した如くに、強化プラスチツクに

させない効果を有する。 As described above, in the present invention, the umbrella rib is molded using reinforced plastic so that it has a substantially T-shaped cross section with respect to the head, so the umbrella rib made of plastic can be made as light as possible. Plastic umbrellas tend to be larger in size because they provide the necessary rigidity, and the head part provides rigidity against bending forces in the lateral direction, while the legs provide rigidity against bending forces in the vertical direction. The bones can be formed to be relatively slender, which has the effect of preventing the group of bundled umbrella bones from becoming bulky, especially when the umbrella is closed.
また本発明においては、該頭部の上面において
軸方向に延長する溝を設けてあるので、該溝によ
り上記した上下方向の屈曲力に対する剛性を緩和
して開傘時の親骨に要求される湾曲形状に可撓変

り開傘時の湾曲形状が強制された後においても良
好な復元性を有して傘骨の変形を防止することが
できる。 Further, in the present invention, since a groove extending in the axial direction is provided on the upper surface of the head, the rigidity against the above-mentioned vertical bending force is relaxed by the groove, and the required curvature of the main rib when the umbrella is opened is reduced. It is possible to flexibly deform the shape, and even after being forced into a curved shape when the umbrella is opened due to long-term use, it has good restorability and can prevent the umbrella ribs from deforming.
