Description

本発明は、種々の形状のベースに、強固な状態で支柱を嵌め入れることのできる支柱の連結構造に関するものである。 The present invention relates to a strut connection structure in which struts can be fitted into bases of various shapes in a solid state.

従来より、ベースに支柱を嵌め入れる支柱の連結手段として、種々の構造のものが提案されている。例えば、特許文献１に開示されているように、ベースとしての棚部材に支柱取付孔を設け、この支柱取付孔に支柱の挿着部を挿着するものがある。
実用新案登録第３０１２３４０号公報 2. Description of the Related Art Conventionally, various structures have been proposed as a column connecting means for fitting a column into a base. For example, as disclosed in Patent Document 1, there is a type in which a column mounting hole is provided in a shelf member as a base, and a column insertion portion is inserted into the column mounting hole.
Utility Model Registration No. 3012340

しかしながら、このような従来における支柱の連結構造は、棚部材の支柱取付孔に支柱の挿着部を挿着し、支柱取付孔の内壁部が支柱の挿着部の外周面に接合する状態で支柱が保持されているので、棚部材と支柱の取付状態が弱いものになり易かった。 However, such a conventional strut connection structure is such that the column insertion portion is inserted into the column mounting hole of the shelf member, and the inner wall portion of the column mounting hole is joined to the outer peripheral surface of the column insertion portion. Since the column is held, the mounting state of the shelf member and the column tends to be weak.

また、従来の支柱の連結構造は、棚部材に上下方向に開口された支柱取付孔を設け、上方から挿着された支柱と下方から挿着された支柱を連結してガタつき等を防止しているが、支柱同士を連結させなくても棚部材に支柱を強固に取り付けることのできる手段の創出が望まれていた。 In addition, the conventional strut connection structure is provided with strut mounting holes that are opened in the vertical direction on the shelf member, and the struts inserted from above and the struts inserted from below are connected to prevent rattling and the like. However, it has been desired to create a means for firmly attaching the support column to the shelf member without connecting the support columns.

そこで、本発明は、如上のような従来存した問題点に鑑み創出されたもので、ベースの嵌合部を二重構造とし、嵌合部の二重構造により生じた空間に支柱の端部を挿入することで、ベースに支柱を強固に嵌め入れることのできる支柱の連結構造を提供することを目的とする。 Therefore, the present invention has been created in view of the above-described conventional problems, and the fitting portion of the base has a double structure, and the end portion of the column is formed in the space generated by the double structure of the fitting portion. It is an object of the present invention to provide a strut connection structure in which a strut can be firmly fitted into a base by inserting a base.

このため、本発明は、所定のベースに嵌合部を設け、ベースの嵌合部に支柱の端部を嵌め入れる支柱の連結構造であり、ベースの嵌合部は、外側部材と内側部材を備え、外側部材と内側部材の間に所定の空間が生じる二重構造とし、支柱の端部を、嵌合部の二重構造により生じた空間に挿入することで、上述した課題を解決した。 For this reason, the present invention is a strut connection structure in which a fitting portion is provided in a predetermined base, and an end portion of the strut is fitted into the fitting portion of the base. The fitting portion of the base includes an outer member and an inner member. The above-mentioned problem has been solved by providing a double structure in which a predetermined space is generated between the outer member and the inner member, and inserting the end portion of the column into the space generated by the double structure of the fitting portion.

また、ベースの嵌合部を、支柱の端部の外周面に当接する外枠部と、支柱の端部の内周面に当接する押圧体により形成したことで、同じく上述した課題を解決した。 Further, the above-mentioned problem has been solved by forming the fitting portion of the base with the outer frame portion that contacts the outer peripheral surface of the end portion of the column and the pressing body that contacts the inner peripheral surface of the end portion of the column. .

さらに、嵌合部の押圧体は、線状部分が支柱の端部の内周面に当接することで、同じく上述した課題を解決した。 Furthermore, the press part of the fitting part solved the above-mentioned problem by the linear part coming into contact with the inner peripheral surface of the end part of the support column.

また、嵌合部の押圧体は、面状部分が支柱の端部の内周面に当接することで、同じく上述した課題を解決した。 Moreover, the pressing body of the fitting part solved the same problem as described above, because the planar portion abuts against the inner peripheral surface of the end portion of the support column.

加えて、支柱の端部を、板状に形成したことで、同じく上述した課題を解決した。 In addition, the above-mentioned problem has been solved by forming the end of the support in a plate shape.

また、支柱の端部を、板枠状に形成したことで、同じく上述した課題を解決した。 Moreover, the problem mentioned above was solved because the edge part of the support | pillar was formed in plate frame shape.

この他、支柱の端部に、側方に突出する突出部材を設け、嵌合部の外側部材に、支柱の突出部材を嵌め込む開口孔を設けたことで、同じく上述した課題を解決した。 In addition, the problem mentioned above was solved by providing the protrusion member which protrudes to the edge part of a support | pillar, and providing the opening hole which fits the protrusion member of a support | pillar in the outer member of the fitting part.

また、支柱の端部に、複数の爪片を設け、嵌合部の外側部材と内側部材を接続する部分に、支柱の爪片を嵌め込む複数の孔を設けたことで、同じく上述した課題を解決した。 In addition, a plurality of claw pieces are provided at the end of the support column, and a plurality of holes for fitting the claw pieces of the support column are provided in a portion connecting the outer member and the inner member of the fitting portion.

さらに、嵌合部を、ベースの上面及び下面に設けたことで、同じく上述した課題を解決した。 Furthermore, the problem mentioned above was solved by providing the fitting part in the upper surface and lower surface of the base.

所定のベース１に嵌合部（Ａ，Ｂ）を設け、ベース１の嵌合部（Ａ，Ｂ）に支柱２の端部を嵌め入れる支柱２の連結構造であり、ベース１の嵌合部（Ａ，Ｂ）は、外側部材（３，１１）と内側部材（４，１２）を備え、外側部材（３，１１）と内側部材（４，１２）の間に所定の空間Ｓが生じる二重構造とし、支柱２の端部を、嵌合部（Ａ，Ｂ）の二重構造により生じた空間Ｓに挿入することにより、ベース１の嵌合部（Ａ，Ｂ）に支柱２を強固に固定できる。 The base 1 is a connecting structure in which a fitting portion (A, B) is provided in a predetermined base 1 and the end of the pillar 2 is fitted into the fitting portion (A, B) of the base 1. (A, B) includes an outer member (3, 11) and an inner member (4, 12), and a predetermined space S is generated between the outer member (3, 11) and the inner member (4, 12). The support 2 is firmly attached to the fitting portion (A, B) of the base 1 by inserting the end portion of the support column 2 into the space S generated by the double structure of the fitting portion (A, B). Can be fixed.

具体的には、ベース１の嵌合部（Ａ，Ｂ）を、支柱２の端部の外周面に当接する外枠部３，１１と、支柱２の端部の内周面に当接する押圧体４，１２により形成したので、支柱２の端部を外枠部３，１１と押圧体４，１２により挟み込んだ状態となり、ベース１の嵌合部（Ａ，Ｂ）に支柱２を強固に固定できる。 Specifically, the fitting portions (A, B) of the base 1 are pressed against the outer frame portions 3 and 11 that are in contact with the outer peripheral surface of the end portion of the support column 2 and the inner peripheral surface of the end portion of the support column 2. Since it is formed by the bodies 4, 12, the end of the support column 2 is sandwiched between the outer frame portions 3, 11 and the pressing bodies 4, 12, and the support column 2 is firmly attached to the fitting portions (A, B) of the base 1. Can be fixed.

また、嵌合部（Ａ，Ｂ）の押圧体４，１２は、線状部分が支柱２の端部の内周面に当接するので、支柱２の端部を外枠部３，１１と線状部分により挟み込んだ状態となり、ベース１の嵌合部（Ａ，Ｂ）に支柱２を強固に固定できる。 Further, since the linear portions of the pressing bodies 4 and 12 of the fitting portions (A and B) are in contact with the inner peripheral surface of the end portion of the column 2, the end portion of the column 2 is connected to the outer frame portions 3 and 11. As a result, the support 2 can be firmly fixed to the fitting portions (A, B) of the base 1.

さらに、嵌合部（Ａ，Ｂ）の押圧体４，１２は、面状部分が支柱２の端部の内周面に当接するので、支柱２の端部を外枠部３，１１と面状部分により挟み込んだ状態となり、ベース１の嵌合部（Ａ，Ｂ）に支柱２を強固に固定できる。 Further, since the pressing members 4 and 12 of the fitting portions (A and B) are in contact with the inner peripheral surface of the end portion of the support column 2, the end portion of the support column 2 faces the outer frame portions 3 and 11. As a result, the support 2 can be firmly fixed to the fitting portions (A, B) of the base 1.

また、支柱２の端部を、板状に形成したときには、嵌合部（Ａ，Ｂ）を構成する外枠部３，１１と押圧体４，１２の間の空間Ｓに支柱２の端部を挿入し、ベース１の嵌合部（Ａ，Ｂ）に支柱２を強固に固定できる。 Further, when the end portion of the support column 2 is formed in a plate shape, the end portion of the support column 2 is inserted into the space S between the outer frame portions 3 and 11 and the pressing bodies 4 and 12 constituting the fitting portions (A and B). , And the support column 2 can be firmly fixed to the fitting portion (A, B) of the base 1.

加えて、支柱２の端部を、板枠状に形成したときには、嵌合部（Ａ，Ｂ）を構成する外枠部３，１１と押圧体４，１２の間に枠状に形成された空間Ｓに支柱２の板枠状の端部を挿入し、ベース１の嵌合部（Ａ，Ｂ）に支柱２をより強固に固定できる。 In addition, when the end portion of the support column 2 is formed in a plate frame shape, it is formed in a frame shape between the outer frame portions 3 and 11 and the pressing bodies 4 and 12 constituting the fitting portions (A and B). The frame-like end of the column 2 can be inserted into the space S, and the column 2 can be more firmly fixed to the fitting portion (A, B) of the base 1.

また、支柱２の端部に、側方に突出する突出部材２３を設け、嵌合部Ｂの外側部材（１１）に、支柱２の突出部材２３を嵌め込む開口孔１５を設けたので、嵌合部Ｂに支柱２の端部を挿入し、支柱２の突出部材２３が嵌合部Ｂの開口孔１５に係合して嵌合部Ｂに挿入された支柱２が引き抜かれてしまうような事態の発生を阻止している。一方、突出部材２３を押圧して突出部材２３を開口孔１５から退出させれば、嵌合部Ｂに挿入された支柱２を簡単に引き抜くことがでる。 Further, since the projecting member 23 projecting sideways is provided at the end of the support column 2 and the opening hole 15 for fitting the projecting member 23 of the support column 2 is provided in the outer member (11) of the fitting portion B. The end of the column 2 is inserted into the joint B, and the protruding member 23 of the column 2 engages with the opening hole 15 of the fitting part B, so that the column 2 inserted into the fitting part B is pulled out. The situation has been prevented. On the other hand, if the protruding member 23 is pressed to retract the protruding member 23 from the opening hole 15, the column 2 inserted in the fitting portion B can be easily pulled out.

この他、支柱２の端部に、複数の爪片１８を設け、嵌合部Ａの外側部材（３）と内側部材（４）を接続する部分に、支柱２の爪片１８を嵌め込む複数の孔１０を設けたときには、嵌合部Ａに支柱２の端部を挿入して支柱２の爪片１８が嵌合部Ａの孔１０に係合し、嵌合部Ａに挿入された支柱２が引き抜かれてしまうような事態の発生を阻止している。 In addition, a plurality of claw pieces 18 are provided at the end portion of the support column 2, and a plurality of claw pieces 18 of the support column 2 are fitted into a portion connecting the outer member (3) and the inner member (4) of the fitting portion A.

外枠部３は、図２に示すように、所定の高さを備えた四角形に形成され、隅部が湾曲している。そして、外枠部３の内周面から若干離れるようにして、外枠部３の内側に押圧体４を配置している。この押圧体４は、外枠部３の形状に合わせて、四角形に形成されている。具体的には、外枠部３と同じ高さを備えた筒状部分５と、筒状部分５の上端部において内側に向けて延設され、中央部に方形状の孔６を備えている板片７により形成されている。 As shown in FIG. 2, the outer frame portion 3 is formed in a quadrangular shape having a predetermined height, and the corner portion is curved. And the press body 4 is arrange | positioned inside the outer frame part 3 so that it may leave | separate from the internal peripheral surface of the outer frame part 3 a little. The pressing body 4 is formed in a quadrangular shape in accordance with the shape of the outer frame portion 3. Specifically, a cylindrical portion 5 having the same height as the outer frame portion 3, an inward extension at the upper end portion of the cylindrical portion 5, and a square hole 6 at the central portion are provided. It is formed by a plate piece 7.

押圧体４の筒状部分５は、全体として四角形であるが、図３に示すように、その隅部における２箇所が湾曲状に形成され、板片７においても対応する２箇所が湾曲状に形成されている。例えば、図１に示すベース１の長手方向に配置されている２個の嵌合部Ａにおいて、互いに向い合う押圧体４の部分が湾曲状に形成されているのである。 Although the cylindrical part 5 of the pressing body 4 is a quadrangle as a whole, as shown in FIG. 3, two places in the corner are formed in a curved shape, and two corresponding parts in the plate piece 7 are also curved. Is formed. For example, in the two fitting portions A arranged in the longitudinal direction of the base 1 shown in FIG. 1, the portions of the pressing bodies 4 facing each other are formed in a curved shape.

嵌合部Ａを構成する外枠部３の内周面と押圧体４の外周面の間には、所定の空間Ｓが生じる二重構造となっている。この二重構造により生じた空間Ｓに、支柱２の端部を挿入するのである。 Between the inner peripheral surface of the outer frame portion 3 constituting the fitting portion A and the outer peripheral surface of the pressing body 4, a predetermined space S is formed. The end of the column 2 is inserted into the space S generated by this double structure.

そして、押圧体４の外周面には、縦方向に複数の突条８を設けている。この突条８の上端部は、図２に示すように、外枠部３の内周面に向けて傾斜状に形成されている。また、外枠部３の上方開口部分も、押圧体４に向けて傾斜状に形成されている。このように、突条８の上端部と外枠部３の上方開放部分を傾斜状に形成することで、支柱２の端部を挿入し易くしている。 A plurality of protrusions 8 are provided on the outer peripheral surface of the pressing body 4 in the vertical direction. As shown in FIG. 2, the upper end portion of the ridge 8 is formed in an inclined shape toward the inner peripheral surface of the outer frame portion 3. The upper opening portion of the outer frame portion 3 is also formed in an inclined shape toward the pressing body 4. As described above, the upper end portion of the protrusion 8 and the upper open portion of the outer frame portion 3 are formed in an inclined shape, so that the end portion of the column 2 can be easily inserted.

尚、図に示す嵌合部Ａは、いずれも四角形の外枠部３と押圧体４により形成されているが、これに限定されることはない。例えば、外枠部３と押圧体４を、円形や三角形・五角形等に形成しても良い。すなわち、外枠部３と押圧体４により、支柱２の端部を挿入できる空間Ｓを形成できれば、外枠部３と押圧体４はどのような形状であっても差し支えない。 In addition, although all the fitting parts A shown in the figure are formed by the rectangular outer frame part 3 and the pressing body 4, it is not limited to this. For example, the outer frame portion 3 and the pressing body 4 may be formed in a circle, a triangle, a pentagon, or the like. In other words, the outer frame 3 and the pressing body 4 may have any shape as long as the outer frame 3 and the pressing body 4 can form a space S into which the end of the support column 2 can be inserted.

また、図に示す押圧体４の外周面には、複数の突条８が設けられており、外枠部３と押圧体４により形成された空間Ｓに支柱２の端部が挿入されたとき、突条８による線状部分が支柱２の端部の内周面に当接するものであるが、これに限定されることはない。例えば、押圧体４に突条８を設けることなく、押圧体４の面状部分が支柱２の端部の内周面に当接するものであっても良い。そして、ベース１の端部を挿入し易くするため、押圧体４の上端に位置する折曲部分を傾斜状に形成してある。 In addition, a plurality of protrusions 8 are provided on the outer peripheral surface of the pressing body 4 shown in the figure, and when the end of the support column 2 is inserted into the space S formed by the outer frame portion 3 and the pressing body 4. The linear portion formed by the ridge 8 is in contact with the inner peripheral surface of the end portion of the column 2, but is not limited to this. For example, the planar portion of the pressing body 4 may be in contact with the inner peripheral surface of the end portion of the support column 2 without providing the protrusion 8 on the pressing body 4. And in order to make it easy to insert the edge part of the base 1, the bending part located in the upper end of the press body 4 is formed in the inclined form.

この他、支柱２の端部の内周面に、押圧体４に設けた点状部分が当接するものであっても良い。また、外枠部３の内周面に所定の突出部材を設けることで、支柱２の端部の外周面に線状部分や点状部分が当接するものであっても良い。 In addition, the dot-like part provided in the pressing body 4 may abut on the inner peripheral surface of the end portion of the column 2. Further, by providing a predetermined protruding member on the inner peripheral surface of the outer frame portion 3, a linear portion or a dotted portion may abut on the outer peripheral surface of the end portion of the support column 2.

実施例２として、図４に示すように、ベース１における下面に嵌合部Ｂを設けた例を説明する。 As Example 2, an example in which a fitting portion B is provided on the lower surface of the base 1 as shown in FIG. 4 will be described.

嵌合部Ｂは、ベース１の四隅に配置されている。この嵌合部Ｂは、図５に示すように、支柱２の端部の外周面に当接する外枠部１１と、支柱２の端部の内周面に当接する押圧体１２により形成されている。 The fitting portions B are arranged at the four corners of the base 1. As shown in FIG. 5, the fitting portion B is formed by an outer frame portion 11 that is in contact with the outer peripheral surface of the end portion of the support column 2 and a pressing body 12 that is in contact with the inner peripheral surface of the end portion of the support column 2.

外枠部１１は、図５に示すように、所定の高さを備えた四角形に形成され、隅部が湾曲している。そして、外枠部１１の内周面から若干離れるようにして、外枠部１１の内側に押圧体１２を配置している。この押圧体１２は、図５・図６に示すように、外枠部１１よりも若干低い高さを備えた四角形の筒状部分１３と、筒状部分１３の外周面に設けた複数の突出板片１４により形成されている。この突出板片１４は、図６に示すように、横幅が長く形成された６個の板片１４ａと、横幅が短く形成された２個の板片１４ｂを筒状部分１３の外周面に設けて形成されている。 As shown in FIG. 5, the outer frame portion 11 is formed in a quadrangular shape having a predetermined height, and the corner portion is curved. And the press body 12 is arrange | positioned inside the outer frame part 11 so that it may leave | separate from the inner peripheral surface of the outer frame part 11 a little. As shown in FIGS. 5 and 6, the pressing body 12 includes a rectangular cylindrical portion 13 having a slightly lower height than the outer frame portion 11 and a plurality of protrusions provided on the outer peripheral surface of the cylindrical portion 13. It is formed by a plate piece 14. As shown in FIG. 6, the protruding plate piece 14 is provided with six plate pieces 14 a having a long width and two plate pieces 14 b having a short width on the outer peripheral surface of the cylindrical portion 13. Is formed.

嵌合部Ｂを構成する外枠部１１の内周面と押圧体１２の突出板片１４の間には、所定の空間Ｓが生じる二重構造となっている。この二重構造により生じた空間Ｓに、支柱２の端部を挿入するのである。 Between the inner peripheral surface of the outer frame part 11 which comprises the fitting part B, and the protrusion plate piece 14 of the press body 12, it has the double structure which the predetermined space S produces. The end of the column 2 is inserted into the space S generated by this double structure.

そして、板片１４ａ，１４ｂの下端部は、図５に示すように、外枠部１１の内周面に向けて傾斜状に形成されている。 And the lower end part of plate piece 14a, 14b is formed in the inclined shape toward the internal peripheral surface of the outer frame part 11, as shown in FIG.

このように、板片１４ａ，１４ｂの下端部を傾斜状に形成することで、支柱２の端部を下方から挿入し易くしている。尚、外枠部１１の下方開口部分も、板片１４ａ，１４ｂに向けて傾斜状に形成すると、支柱２の端部を下方から一層挿入し易くなる。 As described above, the lower end portions of the plate pieces 14a and 14b are formed in an inclined shape, so that the end portion of the support column 2 can be easily inserted from below. In addition, if the downward opening part of the outer frame part 11 is also formed in an inclined shape toward the plate pieces 14a and 14b, it becomes easier to insert the end portion of the column 2 from below.

尚、図に示す嵌合部Ｂは、四角形の外枠部１１と、四角形の筒状部分１３に板片１４ａ，１４ｂを設けた押圧体１２により形成されているが、これに限定されることはない。例えば、円形や三角形・五角形等に形成した外枠部１１と、同じく円形や三角形・五角形等に形成した筒状部分１３に突出板片１４を設けた押圧体１２により嵌合部Ｂを形成しても良い。すなわち、外枠部１１と、筒状部分１３に突出板片１４を設けた押圧体１２により、支柱２の端部を挿入できる空間Ｓを形成できれば、外枠部１１と押圧体１２はどのような形状であっても差し支えない。 In addition, although the fitting part B shown to the figure is formed of the press body 12 which provided the plate pieces 14a and 14b in the square outer frame part 11 and the square cylindrical part 13, it is limited to this. There is no. For example, the fitting portion B is formed by the outer frame portion 11 formed in a circular shape, a triangular shape, a pentagon shape, etc., and the pressing body 12 provided with the protruding plate piece 14 in the cylindrical portion 13 also formed in a circular shape, a triangular shape, a pentagon shape, etc. May be. That is, if the outer frame portion 11 and the pressing body 12 provided with the protruding plate piece 14 on the cylindrical portion 13 can form a space S into which the end portion of the support column 2 can be inserted, how the outer frame portion 11 and the pressing body 12 are arranged. Any shape can be used.
