【０００１】
【発明の属する技術分野】
本発明は、特に、コンパクトに折り畳むことができる多段折畳式洋傘に関する。
【０００２】
【従来の技術】
従来の多段折畳式洋傘の上支骨は、下連繋骨側が開口した断面コの字状のものであったため、折り畳んだときに下連繋骨は上支骨及び下支骨の内部に収容されるが、中間支骨が嵩張ってコンパクトに畳めないという問題があった。
また、従来の多段折畳式洋傘における上連繋骨は、特別な係止具を介して中間支骨に係止されるものであるため、製造コストが嵩むという問題があった。
【０００３】
【発明が解決しようとする課題】
本発明は上記の問題を解決するためなされたものであり、その目的とすることろは、コンパクトに折り畳むことができ、特別な係止具を用いずに上連繋骨を係止できる多段折畳式洋傘を提供することにある。
【０００４】
【課題を解決するための手段】
上記の第一の目的は、上支骨の中間支骨が連結される端部側を、中間支骨を両側から挟むように対面する一対の側板部と、下支骨が連結されている部分付近では、側板部の傘布側の縁部同士を結び、中間支骨側の端部に近づくに従って徐々に下連繋骨側に近づくよう傾斜し、その終端が側板部間の空間を二分している傾斜板部とによって構成し、傘骨を折り畳んだときに、中間支骨の一部を側板部の間に、傾斜板部の一側面に沿って収容し、下支骨と下連繋骨の一部を他の一側面に沿って収容するようにすることによって達成される。
【０００５】
また、上記の第二の目的は、中間支骨に、その傘布側の面にその長さ方向に沿って上連繋骨を収容するための溝部と、その中程に溝部の開口を部分的に塞ぐ当板部と、当板部の対向部に、その長さが当板部の長さ以上のスリットとを設け、上連繋骨が当板部とその対向部の間を通るようにし、上連繋骨が中間支骨の当板部によって溝から外れないようにすることによって達成される。
【０００６】
【発明の実施の態様】
以下、図面により本発明の詳細を説明する。
図１は本発明に係る多段折畳式洋傘の一実施例の開いた状態を示す部分破断説明図、図２は図１に示した洋傘の部分斜視図、図３は図１に示した上支骨のＡ−Ａ断面図、図４は図１に示した洋傘の折畳状態を示す説明図、図５は図３の部分破断説明図である。
図中、１は傘軸、２は上支骨、３は下支骨、４は中間支骨、５は下連繋骨、６は尾骨、７は上連繋骨、８は傘布である。
【０００７】
まず、図１及び図２について説明する。
傘軸１は三段伸縮式のものであり、上端に固定される上ろくろ１０と、傘軸１に同軸に摺動自在に設けられる下ろくろ１１と、下端に図示しない傘柄とを具備する。
上支骨２は、一方の端部が上ろくろ１０に連結される繊維強化樹脂製のものである。
この上支骨２は、上ろくろ１０側の約半分は角柱状であり、残りの部分は、側板部２０、２１と、傾斜板部２２とから成る。
【０００８】
側板部２０、２１は、それぞれ上支骨２の回動軸に直角な平面で、所定距離を介して対向している。
傾斜板部２２は、上支骨２の中程では側板部２０、２１の傘布８側の縁部同士を結び、側板部２０、２１の端部に近づくに従って徐々に傘布８とは反対側の縁部に近づくよう傾斜し、その端部から所定距離離れた位置で、側板部２０、２１の間の空間を二分して終端する。
このため、この上支骨２は、その傾斜板部２２の中程では、図３に示したように、断面Ｈ字状になっている。
【０００９】
下支骨３は、両端に連結部を有し、その外幅が上支骨２の側板部２０、２１の内幅より狭い、断面コの字状の繊維強化樹脂製のものである。
この下支骨３は、断面コの字状の部分の開口が上支骨２側を向くよう、一方の端部が下ろくろ１１に連結され、他方の端部が上支骨２の側板部２０、２１の間に挟まれるよう上支骨２の中間部に連結される。
中間支骨４は、一方の端部近傍が、上支骨２の、上ろくろ１０が連結された方とは反対側の端部に連結される繊維強化樹脂製のものである。
【００１０】
この中間支骨４は、傘布８側の面にその長さ方向に沿って、中程の一部が当板部４１によって塞がれている溝部４０を有し、また、その当板部４１の対向する部分には、長さが当板部４１の長さの３倍程度のスリット４２を有する。
この中間支骨４に、上記のような溝部４０、当板部４１及びスリット４２を設けるには、まず、傘布８側の面に、当板部４１となる部分で、途中で途切れる所定の深さの二条の溝を削り、次に、その反対側から、スリット４２を形成する位置に、当板部４１を削り落とさない深さの溝を削り、溝部４０を連続させるとよい。
【００１１】
また、この中間支骨４は、その両側面の、傘布とは反対側の縁部に沿って、中間支骨４の上支骨２が連結されている側の端部からその中間部付近にかけて、その両側面から両側に張り出す翼部４３を有する。
下連繋骨５は金属板を断面Ｕ字状に成型して成るものであって、一方の端部が、下支骨３の、上支骨２が結合された側の端部近傍に連結され、他方の端部が、中間支骨４の、上支骨２が結合された側の端部に結合される。
【００１２】
尾骨６は剛性のある金属棒の一端に連結具を設けて成るものであり、その連結具の端部近傍の部分が、中間支骨４の、上支骨２が結合された方とは反対側の端部に連結される。
上連繋骨７は弾性のある金属線であり、一方の端部が、下連繋骨５の、中間支骨４が結合された側の端部近傍に連結され、他方の端部が、上支骨２の側板部２０、２１の間を抜け、中間支骨４の溝部４０を通り、当板部４１を潜って、尾骨６の接続具の端部に連結される。
この傘骨の上側の一面には傘布８が張られる。
【００１３】
上記のように構成される本発明に係る多段折畳式洋傘を畳むと、図４に示したように、上支骨２の側板部２０、２１の間の傘軸１側には、下支骨３の一部と、下連繋骨５の一部が収まり、また、その反対側には、中間支骨４の一部が傾斜板２２に沿って収まるものである。
このとき、中間支骨４と下連繋骨５とは、図５に示したように、上支骨２の傾斜板部２２を挟んで極めて近接し、上支骨２の側板部２０、２１の間の空間には遊びがほとんどなくなるので、洋傘をコンパクトに折り畳むことができる。
また、この洋傘の中間支骨４は、一体に製造されるので、製造コストを低くでき、また、この中間支骨４に案内される上連繋骨７は、中間支骨４との接触面積が少なく、傘の開閉がスムーズになり、さらに、中間支骨４の翼部４３、４４は、傘を開いたときの傘骨の強度を大幅に高めるものである。
【００１４】
なお、本発明は如上の実施例に限定されるものではなく、各支骨等の連結方法や、材質、形状等は、本発明の目的の範囲内で自由に設計変更し得るものであり、本発明は上記の説明から当業者が容易に想到し得る総ての変更実施例を包摂するものである。
【００１５】
【発明の効果】
本発明に係る多段折畳式洋傘は如上の如く構成されるので、本発明によるときは、コンパクトに折り畳むことができると共に、製造コストを低く抑えることができる。

BACKGROUND OF THE INVENTION
The present invention particularly relates to a multi-stage foldable western umbrella that can be folded compactly.
[0002]
[Prior art]
Since the conventional upper fulcrum of the multi-fold foldable western umbrella has a U-shaped cross-section with an opening on the lower linking bone side, the lower linking bone is accommodated inside the upper and lower fulcrum when folded. However, there was a problem that the intermediate support was bulky and could not be folded compactly.
Moreover, since the upper continuous bone in the conventional multi-stage folding type western umbrella is locked to the intermediate support via a special locking tool, there is a problem that the manufacturing cost increases.
[0003]
[Problems to be solved by the invention]
The present invention has been made to solve the above-described problems, and the object of the present invention is to provide a multi-stage fold that can be folded compactly and can lock upper continuous bones without using a special locking tool. It is to provide a Western-style umbrella.
[0004]
[Means for Solving the Problems]
The first object is to connect a pair of side plates facing the end of the upper support to which the intermediate support is connected, and the lower support. In the vicinity, the edges of the side plate parts are connected to each other on the side of the umbrella cloth, and gradually incline toward the side of the lower linkage as it approaches the end of the intermediate fulcrum, and the end bisects the space between the side plates. When the umbrella bone is folded, a part of the intermediate frame is accommodated between the side plates along one side of the inclined plate, and the lower and lower joints This is accomplished by accommodating a portion along one other side.
[0005]
In addition, the second object is to provide a groove portion for accommodating the upper continuous bone along the length direction on the surface of the umbrella cloth on the intermediate support bone, and an opening of the groove portion in the middle. The plate portion that is closed and the opposite portion of the plate portion is provided with a slit whose length is longer than the length of the plate portion, so that the upper connecting bone passes between the plate portion and the opposite portion, This is achieved by preventing the upper continuous link from being removed from the groove by the abutment portion of the intermediate fulcrum.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, details of the present invention will be described with reference to the drawings.
FIG. 1 is a partially broken explanatory view showing an opened state of an embodiment of a multi-stage folding western umbrella according to the present invention, FIG. 2 is a partial perspective view of the western umbrella shown in FIG. 1, and FIG. 3 is a top view shown in FIG. FIG. 4 is an explanatory view showing the folded state of the umbrella shown in FIG. 1, and FIG. 5 is a partially broken explanatory view of FIG.
In the figure, 1 is an umbrella shaft, 2 is an upper support, 3 is a lower support, 4 is an intermediate support, 5 is a lower link, 6 is a tailbone, 7 is an upper link, and 8 is an umbrella cloth.
[0007]
First, FIG. 1 and FIG. 2 will be described.
The umbrella shaft 1 is a three-stage telescopic type, and includes an upper skull 10 fixed to the upper end, a lower skull 11 provided coaxially and slidably on the umbrella shaft 1, and an umbrella handle (not shown) at the lower end. .
The upper support frame 2 is made of a fiber reinforced resin having one end connected to the upper crossbone 10.
About half of the upper support frame 2 on the side of the upper handle 10 has a prismatic shape, and the remaining part is composed of side plate portions 20 and 21 and an inclined plate portion 22.
[0008]
The side plate portions 20 and 21 are planes perpendicular to the rotation axis of the upper support 2 and are opposed to each other through a predetermined distance.
The inclined plate portion 22 connects the edges of the side plate portions 20 and 21 on the side of the umbrella cloth 8 in the middle of the upper support frame 2, and gradually becomes opposite to the umbrella cloth 8 as it approaches the end portions of the side plate portions 20 and 21. It inclines so that it may approach the edge part of a side, and divides the space between the side-plate parts 20 and 21 in the position which left | separated predetermined distance from the edge part, and terminates.
For this reason, the upper support frame 2 has an H-shaped cross section as shown in FIG. 3 in the middle of the inclined plate portion 22.
[0009]
The lower support frame 3 is made of a fiber reinforced resin having a U-shaped cross section, which has connecting portions at both ends and whose outer width is narrower than the inner width of the side plates 20 and 21 of the upper support frame 2.
The lower support frame 3 has one end connected to the lower cross 11 so that the opening of the U-shaped portion of the cross section faces the upper support 2 side, and the other end is the side plate portion of the upper support 2 It connects with the intermediate part of the upper support 2 so that it may be pinched | interposed between 20,21.
The intermediate support 4 is made of a fiber reinforced resin whose one end is connected to the end of the upper support 2 opposite to the side to which the upper crossbone 10 is connected.
[0010]
The intermediate support frame 4 has a groove portion 40 which is partly covered by the abutting plate portion 41 along the length direction on the surface of the umbrella cloth 8, and the abutting plate portion. 41 has a slit 42 whose length is about three times the length of the abutting plate portion 41.
In order to provide the intermediate support 4 with the groove portion 40, the abutment plate portion 41, and the slit 42 as described above, first, on the surface on the umbrella cloth 8 side, a portion that becomes the abutment plate portion 41 is interrupted in the middle. It is advisable to cut two grooves having a depth, and then, from the opposite side, to cut the groove having a depth that does not scrape the abutting plate portion 41 at a position where the slit 42 is formed, and to continue the groove portion 40.
[0011]
Further, the intermediate support frame 4 is located in the vicinity of the intermediate part from the end part on the side where the upper support frame 2 of the intermediate support frame 4 is connected along the edge part on the opposite side to the umbrella cloth on both side surfaces. And has wings 43 projecting from both side surfaces to both sides.
The lower continuous link 5 is formed by molding a metal plate in a U-shaped cross section, and one end is connected to the vicinity of the end of the lower support 3 on the side where the upper support 2 is joined. The other end is joined to the end of the intermediate support 4 on the side to which the upper support 2 is joined.
[0012]
The coccyx 6 is formed by providing a connecting tool at one end of a rigid metal rod, and the portion near the end of the connecting tool is opposite to the intermediate support 4 to which the upper support 2 is coupled. Connected to the end of the side.
The upper continuous bone 7 is an elastic metal wire, one end of which is connected to the vicinity of the end of the lower continuous bone 5 on the side where the intermediate support 4 is joined, and the other end is connected to the upper support. It passes between the side plate portions 20, 21 of the bone 2, passes through the groove portion 40 of the intermediate support frame 4, enters the abutment plate portion 41, and is connected to the end portion of the connection tool of the tailbone 6.
An umbrella cloth 8 is stretched on the upper surface of the umbrella bone.
[0013]
When the multi-stage foldable western umbrella according to the present invention configured as described above is folded, as shown in FIG. 4, the umbrella shaft 1 between the side plate portions 20 and 21 of the upper support frame 2 has a lower support. A part of the bone 3 and a part of the lower linkage bone 5 are accommodated, and a part of the intermediate support frame 4 is accommodated along the inclined plate 22 on the opposite side.
At this time, as shown in FIG. 5, the intermediate support frame 4 and the lower joint link 5 are extremely close to each other with the inclined plate portion 22 of the upper support frame 2 interposed therebetween, and the side plate units 20 and 21 of the upper support frame 2. There is almost no play in the space between them, so you can fold the western umbrella compactly.
In addition, since the intermediate support 4 of the western umbrella is manufactured integrally, the manufacturing cost can be reduced, and the upper connecting bone 7 guided by the intermediate support 4 has a contact area with the intermediate support 4. Therefore, the opening and closing of the umbrella is smooth, and the wing parts 43 and 44 of the intermediate support frame 4 significantly increase the strength of the umbrella bone when the umbrella is opened.
