しかしながら、従来のキャップは、実用性はあるものの、外観上、見劣りがする。そのため、丈夫で、且つ、意匠的にも優れたキャップが求められている。   However, the conventional cap is inferior in appearance although it has practicality. Therefore, there is a demand for a cap that is strong and excellent in design.

本発明は、かかる現状から、簡単な構成を有しながら、丈夫、且つ、美麗なキャップを提供することを目的としている。   An object of the present invention is to provide a cap that is strong and beautiful while having a simple configuration.

上記課題を解決するため、本発明は、中空球体状でその球面の一部に開口部を有する頭球部材と、その開口部に挿入嵌着する基台とからなる柵の支柱のキャップであって、頭球部材の開口部を基台の支持筒部に嵌合支持し、その基台の下方から支持筒部の内径に沿って棒状支持体を挿入すると共に、頭球部材の上方から凹状型体で押圧して、前記棒状支持体の進行によって基台の支持筒部の上端部を拡開させて嵌合支持部分をカシメて固定するという手段を採用した。   In order to solve the above-mentioned problems, the present invention is a cap of a fence post comprising a head sphere member having a hollow sphere shape and having an opening in a part of its spherical surface, and a base inserted and fitted into the opening. The opening of the head ball member is fitted to and supported by the support cylinder portion of the base, and a rod-like support body is inserted along the inner diameter of the support cylinder portion from below the base and is recessed from above the head ball member. A means of pressing with a mold and expanding the upper end portion of the support cylindrical portion of the base by the progress of the rod-shaped support and crimping and fixing the fitting support portion was adopted.

そして、頭球部材は、金属円板を、凹型半球面を有する金型で深絞り加工して底部に半球面を有する有底筒体を形成し、さらに、この有底筒体の開口側は凹型半球面を有する金型で開口を閉塞しないように絞り加工して中空球体状に成形するという手段を採用した。   The head ball member is formed by deep drawing a metal disk with a mold having a concave hemispherical surface to form a bottomed cylindrical body having a hemispherical surface at the bottom, and the opening side of the bottomed cylindrical body is A means of drawing into a hollow sphere by drawing so as not to close the opening with a mold having a concave hemispherical surface was adopted.

また、基体は、金属円板を絞り加工により有底の円筒状に成形し、さらに、絞り加工で直径の異なる二段の円錐台形状としたうえ、その底部に孔を穿設して、先細で上記頭球部材の開口部に挿入可能な支持筒部と支柱の径に見合う径の台座筒部を成形するという手段を採用した。   In addition, the base is formed into a cylindrical shape with a bottom by drawing a metal disk, and further formed into a two-stage frustoconical shape with different diameters by drawing, and a hole is drilled in the bottom to taper the base. Thus, a means for forming a support cylinder part that can be inserted into the opening of the head ball member and a base cylinder part having a diameter corresponding to the diameter of the support column is employed.

上記構成に係る本発明のキャップは、継ぎ目のない真球に近い頭球部材と継ぎ目のない基台が、カシメにより互いに堅固に固定されるため、丈夫で長期に亘り経年劣化しないキャップとなる。   The cap of the present invention according to the above configuration is a strong cap that does not deteriorate over time over a long period of time, because the head member close to the true sphere and the seamless base are firmly fixed to each other by caulking.

以下、本発明に係る柵の支柱のキャップに関して、好ましい実施形態を図面について説明する。   DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a fence post cap according to the present invention will be described below with reference to the drawings.

図１において、（Ａ）はキャップの完成斜視図であり、（Ｂ）はその中央縦断面図である。本発明のキャップは、図示するように、所定の直径を有する中空の球体状で、その球面の一部を切り欠いてなる円状の開口部１ａを有する頭球部材１と、この頭球部材１を支持する円筒状の基台２とからなる。また、基台２は、上記頭球部材１の開口部１ａに挿入係合する先細の支持筒部２ａと、柵の支柱の頭部に適宜な手段で嵌合係着可能な台座筒部２ｂとを有している。そして、このキャップは、図４に示すように、柵の支柱（Ｐ）の頭部に適宜な手段で嵌着するものである。   In FIG. 1, (A) is a completed perspective view of the cap, and (B) is a central longitudinal sectional view thereof. As shown in the figure, the cap of the present invention is a hollow sphere having a predetermined diameter, a head ball member 1 having a circular opening 1a formed by cutting out a part of the spherical surface, and the head ball member. 1 and a cylindrical base 2 that supports 1. The base 2 includes a tapered support cylinder 2a that is inserted into and engaged with the opening 1a of the head ball member 1, and a base cylinder 2b that can be fitted and engaged with the head of the fence column by appropriate means. And have. Then, as shown in FIG. 4, the cap is fitted to the head of the support (P) of the fence by an appropriate means.

この頭球部材１は、例えば、所定厚さの適宜な金属板を円板状に打ち抜いた上、この金属円板を所定の凹型半球面を有する金型に押圧して深絞り加工することで底部に半球面を有する有底筒体を形成し、さらに、この有底筒体の開口側から凹型半球面を有する金型で上下方向に押圧して絞り加工を施すことで残り部分も半球状となり、全体としてほぼ球体に成形される。これにより、継ぎ目のない中空球体状に成形することができる。その際、所定の直径の開口部１ａを閉塞しないで残して成形することで、図示した開口部１ａを有する頭球部材１が得られる。   For example, the head ball member 1 is formed by punching an appropriate metal plate having a predetermined thickness into a disc shape, and pressing the metal disc against a die having a predetermined concave hemispherical surface for deep drawing. A bottomed cylindrical body having a hemispherical surface is formed at the bottom, and further, the remaining part is also hemispherical by pressing up and down with a mold having a concave hemispherical surface from the opening side of the bottomed cylindrical body As a whole, it is almost formed into a sphere. Thereby, it can shape | mold in the shape of a hollow sphere without a joint. At this time, the head ball member 1 having the illustrated opening 1a is obtained by forming the opening 1a having a predetermined diameter without being closed.

なお、絞り加工などの際、球面の曲率を一定値にすることでほぼ真球となるので、意匠的に美麗な外観を呈する。但し、全体の曲率が一致しない場合であっても、球体に近い外観を呈し、実用性に問題が生じることはない。   Note that, when drawing or the like, the spherical surface has a substantially spherical shape by making the curvature of the surface constant, so that it has a beautiful appearance in design. However, even if the curvatures of the whole do not match, the appearance is close to a sphere, and there is no problem in practicality.

このように、例えば、一枚の金属円板を絞り工程などを経て球体に成形することができるので、成形工程が単純化されるとともに、真球に近く、継ぎ目のない頭球部材１を比較的容易に成形することができる。   In this way, for example, a single metal disk can be formed into a sphere through a drawing process, etc., so that the forming process is simplified and a head ball member 1 that is close to a true sphere and has no joints is compared. Can be easily molded.

次に、基台２については、頭球部材１と同様に、例えば、金属円板を絞り加工などにより有底の円筒状に成形し、さらに、絞り加工で直径の異なる二段の円錐台形状とし、その底部に所定径の孔を穿設することにより成形することができる。これによって、先細で上記頭球部材１の開口部１ａに挿入可能な支持筒部２ａと支柱の径に見合う径の台座筒部２ｂを有する継ぎ目のない基台２を得ることができる。   Next, with respect to the base 2, as with the head ball member 1, for example, a metal disc is formed into a bottomed cylindrical shape by drawing or the like, and further, a two-stage truncated cone shape having different diameters by drawing. And by forming a hole with a predetermined diameter in the bottom thereof. As a result, it is possible to obtain a seamless base 2 having a support cylindrical portion 2a that can be inserted into the opening 1a of the head ball member 1 and a pedestal cylindrical portion 2b having a diameter corresponding to the diameter of the support column.

このように、基台２についても、一枚の金属円板に絞り加工などを施すことによって成形することができるので、寸法の正確な基台を容易に得ることができる。また、継ぎ目がなく堅牢である。   Thus, since the base 2 can also be formed by subjecting one metal disk to a drawing process or the like, it is possible to easily obtain a base having an accurate dimension. It is also seamless and robust.

次に、上記形状の頭部部材１と基台２の組み立てについて、図２に従って説明する。上述したように、頭球部材１は、その周面の一部に所定径の開口部１ａを有している。一方、基台２は、上記頭球部材１の開口部１ａに挿入係合する先細の支持筒部２ａと、柵の支柱の頭部に適宜な手段で嵌合係着可能な台座筒部２ｂとを有している。そこで、先ず、同図（ａ）に示すように、頭球部材１の開口部１ａを基台２の支持筒部２ａに嵌合させて、同図（ｂ）に示すように、支持筒部２ａの高さの途中に頭球部材１が位置するようにする。次に、同図（ｃ）に示すように、基台２の下方から支持筒部２ａの内側に沿って棒状支持体３を挿入すると共に、頭球部材１の上方からは、凹状金型４で押圧する。このとき、棒状支持体３の直径は、上記頭球部材１の開口部１ａと基台２の支持筒部２ａとの接触部分における支持筒部２ａの内径とほぼ一致する径を有する。これにより、凹状金型４で頭球部材１を押圧すると、（ｄ）に示すように、棒状支持体３が支持筒部２ａ内を進行し、その上端部を拡開させて（図（ｄ）左右方向の矢印参照。）、該部をカシメることができる。その結果、図１に示したように、基台２に頭球部材１を堅固に固定したキャップを得ることができる。かかるキャップは、丈夫であり経年劣化が少ないものとなる。   Next, the assembly of the head member 1 and the base 2 having the above shape will be described with reference to FIG. As described above, the headball member 1 has an opening 1a having a predetermined diameter on a part of its peripheral surface. On the other hand, the base 2 includes a tapered support tube portion 2a inserted into and engaged with the opening 1a of the head ball member 1, and a base tube portion 2b that can be fitted and attached to the head portion of the pillar of the fence by an appropriate means. And have. Therefore, first, as shown in FIG. 4A, the opening 1a of the head ball member 1 is fitted into the support cylinder 2a of the base 2, and the support cylinder is shown in FIG. The head ball member 1 is positioned in the middle of the height 2a. Next, as shown in FIG. 3C, a rod-like support 3 is inserted along the inside of the support cylinder 2a from below the base 2, and from the top of the headball member 1, a concave mold 4 is inserted. Press. At this time, the diameter of the rod-shaped support 3 has a diameter that substantially coincides with the inner diameter of the support cylinder 2a at the contact portion between the opening 1a of the head ball member 1 and the support cylinder 2a of the base 2. Thus, when the head ball member 1 is pressed with the concave mold 4, as shown in (d), the rod-like support body 3 advances in the support tube portion 2a, and its upper end portion is expanded (FIG. (D). ) Refer to the left and right arrows.), This part can be caulked. As a result, as shown in FIG. 1, a cap in which the head ball member 1 is firmly fixed to the base 2 can be obtained. Such a cap is strong and has little deterioration over time.

なお、本実施形態において、上記頭球部材１、及び、基台２の大きさは、設置する支柱の直径に応じて適宜選択するもので、任意に決定できる。これにより、キャップ全体の大きさも決定される。   In addition, in this embodiment, the magnitude | size of the said head ball member 1 and the base 2 is suitably selected according to the diameter of the support | pillar to install, and can be arbitrarily determined. Thereby, the size of the entire cap is also determined.

また、上記頭球部材１及び基台２の素材としては、金属材料であれば特に限定するものではなく、鉄、ステンレス、アルミニウム、真鍮、銅などの金属板を必要に応じて適宜選択することができる。この場合、屋外に設置されるものについては、耐腐食性に優れた素材を選択することが好ましい。   Moreover, as a raw material of the said head ball member 1 and the base 2, if it is a metal material, it will not specifically limit, Metal plates, such as iron, stainless steel, aluminum, brass, copper, will be selected suitably as needed. Can do. In this case, it is preferable to select a material excellent in corrosion resistance for those installed outdoors.

なお、上述した頭球部材１の開口部１ａは、上記したものに限らず、例えば、図３（ａ）に示すように、開口縁部が内側に嵌入したような形状であってもよい。この場合は、上記頭球部材１の開口部１ａに、開口部１ａの径より少し大きい棒状体（図示せず）を押入して、開口縁部を内側に陥入させて形成することができる。また、同図（ｂ）に示すように、開口縁部が球面より外側に延伸した態様であってもよい。そして、いずれの形状であっても、この頭球部材１は、前述したカシメによる手段、又は、他の公知の手段により基台２に嵌着、固定して、キャップが完成する。   In addition, the opening part 1a of the head ball member 1 described above is not limited to the above-described one, and for example, as illustrated in FIG. In this case, a rod-like body (not shown) slightly larger than the diameter of the opening 1a can be pushed into the opening 1a of the head ball member 1 so that the opening edge is indented inward. . Further, as shown in FIG. 2B, the opening edge may be extended outward from the spherical surface. In any shape, the head ball member 1 is fitted and fixed to the base 2 by the aforementioned caulking means or other known means, thereby completing the cap.

上記頭球部材１と基台２を組み立てたキャップは、その接合部をカシメ等により強固に接合できるので、非常に堅固であり壊れにくく、長期に亘る使用が可能である。また、意匠的にも、曲線と直線の結合からなる美感があり、図４に示すように、柵の連続する支柱（Ｐ）に使用することにより、一定の美感を生じさせることができる。   Since the cap assembled from the head ball member 1 and the base 2 can be firmly joined by caulking or the like, the cap is very firm and not easily broken, and can be used for a long time. Also, in terms of design, there is an aesthetic sense composed of a combination of a curved line and a straight line. As shown in FIG.
