It is comprised from the intermediate joint 2 which connects the part 1 and the 2nd clip part 3. FIG. The joint structure of the present invention can be used at one place or two places of the bulletin board display tool 10. That is, the joint structure of the present invention is used for one or both of the joint portion 20a of the first clip portion 1 and the intermediate joint 2 or the joint portion 20b of the second clip portion 3 and the intermediate joint 2. Of these, the use of both the first clip portion 1 and the joint portion 20a of the intermediate joint 2 and the joint portion 20b of the second clip portion 3 and the intermediate joint 2 can effectively obtain the effects of the present invention. preferable. Since the two joint structures in the bulletin board display tool 10 have the same structure, the following description will be given on the joint portion 20a of the first clip portion 1 and the intermediate joint 2.

継手構造体（継手部分）２０ａは、第１クリップ本体部（第１支持本体部）１１の連結側の端面１３に、第１ピン孔１２１を有する一対の両腕部１２を備える第１クリップ部（第１支持体）１と、中間継手本体部（第２支持本体部）２１の連結側の端面に、柱状且つ先端がアールで、第２ピン孔２２１を有する、一対の両腕部１２間に嵌る突部２２を備える中間継手（第２支持体）２と、第１ピン孔１２１と第２ピン孔２２１に挿入されて、第１クリップ部１と中間継手２を連結するピン５と、を備え、前記式（１）及び前記式（２）を満たすものである。 The joint structure (joint portion) 20 a includes a pair of both arm portions 12 having a first pin hole 121 on the end surface 13 on the connection side of the first clip body portion (first support body portion) 11. (First support) 1 and a pair of arms 12 having a columnar shape and a rounded tip and a second pin hole 221 on an end surface on the connection side of the intermediate joint body (second support body) 21 An intermediate joint (second support) 2 having a protrusion 22 that fits into the first pin hole 121 and the second pin hole 221, and a pin 5 that connects the first clip part 1 and the intermediate joint 2; And satisfying the formula (1) and the formula (2).

図４及び図５に示すように、前記式（１）及び式（２）中、Ａは第１ピン孔１２１の中心から第１クリップ本体部１１の連結側の端面１３までの距離を示し、Ｂは中間継手２の先端のアールの半径であって、第２ピン孔２２１の中心から先端までの距離を示し、Ｃは突部２における第２ピン孔２２１の中心から左右両側端２２２までの距離を示す。 As shown in FIGS. 4 and 5, in the above formulas (1) and (2), A represents the distance from the center of the first pin hole 121 to the end face 13 on the connection side of the first clip body 11, B is the radius of the radius of the tip of the intermediate joint 2 and indicates the distance from the center of the second pin hole 221 to the tip, and C is the distance from the center of the second pin hole 221 to the left and right side ends 222 of the protrusion 2. Indicates distance.

なお、Ｂ＞Ａであるが、具体的にはＢはＡより、０．１〜０．５ｍｍ大きい寸法である。ＢをＡより僅かに大きくすることにより、第１クリップ部１と中間継手２を図１に示すような起立状態とする際、継手部の摩擦抵抗に抗して手で回動できると共に、第１クリップ部１と中間継手２の支持負荷を適度なものとすることができる。また、Ａ＝Ｃであるが、この等式はＡがＣより僅かに大きい寸法のものを許容するものである。ＡがＣより僅かに大きい寸法であっても、第１クリップ部１と中間継手２の組み付け初期状態におけるピン５の挿入の妨げとなるものではない。 In addition, although B> A, specifically, B is 0.1 to 0.5 mm larger than A. By making B slightly larger than A, the first clip portion 1 and the intermediate joint 2 can be turned by hand against the frictional resistance of the joint portion when the first clip portion 1 and the intermediate joint 2 are in the standing state as shown in FIG. The support load of 1 clip part 1 and the intermediate joint 2 can be made moderate. Also, although A = C, this equation allows that A is slightly larger than C. Even if A is slightly larger than C, it does not hinder insertion of the pin 5 in the initial assembly state of the first clip portion 1 and the intermediate joint 2.

掲示物表示具１０において、一対の両腕部１２の先端形状は丸み形状であるが、これに限定されず、先端両側角部が丸みの柱状であってもよい。また、突部２２は、図３のような形状に限定されず、両腕形状であってもよい。 In the posted object display 10, the tip shape of the pair of both arm portions 12 is round, but the present invention is not limited to this, and may be a column shape with rounded corners on both sides of the tip. Further, the protrusion 22 is not limited to the shape as shown in FIG.

また、第１クリップ部１及び中間継手２は樹脂製が好ましく、このうち、いずれか一方が硬質樹脂製であり、他方が該硬質樹脂より柔らかい樹脂製であることが、第１クリップ部１と中間継手２を、例えば起立状態のような使用状態とする際、継手部の摩擦抵抗に抗して手で回動できると共に、第１クリップ部１と中間継手２の支持負荷を適度なものとすることができる点で好ましい。硬質樹脂としては、特に制限されないが、アクリロニトリルブタジエンスチレン（ＡＢＳ）が挙げられる。また、当該硬質樹脂より柔らかい樹脂としては、特に制限されないが、例えばポリアセタール（ＰＯＭ）が挙げられる。 Further, the first clip portion 1 and the intermediate joint 2 are preferably made of resin, and one of them is made of hard resin, and the other is made of resin softer than the hard resin. When the intermediate joint 2 is put into a use state such as a standing state, for example, the intermediate joint 2 can be rotated manually against the frictional resistance of the joint portion, and the support load of the first clip portion 1 and the intermediate joint 2 can be moderate. This is preferable in that it can be performed. Although it does not restrict | limit especially as hard resin, Acrylonitrile butadiene styrene (ABS) is mentioned. In addition, the softer resin than the hard resin is not particularly limited, and examples thereof include polyacetal (POM).

次に、継手構造体２０ａの組み付け方法を説明する。先ず、第１クリップ部１と中間継手２を、互いに直交する角度におき（図４参照）、且つ第１ピン孔１２１と第２ピン孔２２１が合致する位置で位置合せを行い、第１ピン孔１２１と第２ピン孔２２１にピン５を挿入する（図５参照）。この場合、ＡとＣは同じ又はＣはＡよりやや小さいため、両者の位置決めにおいて障害となる部材は存在せず、第１ピン孔１２１と第２ピン孔２２１を容易に完全一致させることができ、ピン５の挿入が容易となる。なお、図７に示すように、第１クリップ部１と中間継手２が、直列に並ぶような配置角度の場合、Ｂ＞Ａの関係から、ピン孔を一致させる位置決めを行ったとしても、第１ピン孔１２１の中心より、第２ピン孔２２１の中心は下方に位置するため、第１ピン孔１２１と第２ピン孔２２１は完全一致せず、ピン５を第１ピン孔１２１と第２ピン孔２２１に挿入することができない。 Next, a method for assembling the joint structure 20a will be described. First, the first clip portion 1 and the intermediate joint 2 are placed at an angle orthogonal to each other (see FIG. 4), and aligned at a position where the first pin hole 121 and the second pin hole 221 coincide with each other. The pin 5 is inserted into the hole 121 and the second pin hole 221 (see FIG. 5). In this case, since A and C are the same or C is slightly smaller than A, there is no member that obstructs the positioning of both, and the first pin hole 121 and the second pin hole 221 can be easily and completely matched. The pin 5 can be easily inserted. As shown in FIG. 7, when the first clip portion 1 and the intermediate joint 2 have an arrangement angle such that they are arranged in series, the relationship of B> A can be used even if positioning to match the pin holes is performed. Since the center of the second pin hole 221 is located below the center of the first pin hole 121, the first pin hole 121 and the second pin hole 221 do not completely coincide, and the pin 5 is connected to the first pin hole 121 and the second pin hole 121. It cannot be inserted into the pin hole 221.

第１ピン孔１２１と第２ピン孔２２１及びピン５の係合は圧入による係合であることが、一度挿入したピン５が容易には抜けない点で好ましい。圧入による係合としては、ピン５の径を、第１ピン孔１２１と第２ピン孔２２１の内径と同じ若しくはやや大きくし、且つピン５を軸方向に割れ目を入れた割りピンとして、ピン５が第１ピン孔１２１と第２ピン孔２２１に挿入された後は、割りピンの弾発力により係合強度を高める方法が挙げられる。 The engagement of the first pin hole 121, the second pin hole 221 and the pin 5 is preferably press-fitting so that the pin 5 once inserted cannot be easily removed. As the engagement by press-fitting, the diameter of the pin 5 is the same as or slightly larger than the inner diameters of the first pin hole 121 and the second pin hole 221, and the pin 5 is a split pin with a crack in the axial direction. Is inserted into the first pin hole 121 and the second pin hole 221, there is a method of increasing the engagement strength by the elastic force of the split pin.

次いで、第１クリップ部１又は中間継手２を、それぞれ第１クリップ部１又は中間継手２に対して回動させて、連結部に負荷がかかる支持を行う。すなわち、図５の状態から、例えば中間継手２を図５の矢印の方向に回転させると、図６に示すように、中間継手２の突部２２の先端の丸み部（第２ピン孔２２１の中心から半径Ｒの円弧）２２３と第１クリップ本体部１１の連結側の端面１３とが接触する（図６参照）。この場合、第１クリップ部１と中間継手２はピン５により互いのピン孔の中心は一致しており、且つＢ＞Ａであるから、中間継手２の突部２の先端の丸み部２２３と第１クリップ本体部１１の連結側の端面１３との接触部において、（Ｂ−Ａ）の寸法に相当する干渉寸法Ｘが発生する。これにより、第１クリップ部１又は中間継手２はその連結部分において、支持負荷が発生し、強固な支持力を得ることができる。なお、この強固な支持力は、図６中、二点鎖線で示す広い範囲で得られるため、設置スペースや設置場所等により、図１に示すような起立姿勢が採れないような場合、連結部で屈曲させて支持することもできる。 Subsequently, the 1st clip part 1 or the intermediate joint 2 is rotated with respect to the 1st clip part 1 or the intermediate joint 2, respectively, and the load which applies a load to a connection part is performed. That is, when the intermediate joint 2 is rotated in the direction of the arrow in FIG. 5 from the state of FIG. 5, for example, as shown in FIG. 6, the rounded portion (the second pin hole 221 of the second pin hole 221). The arc 223 having a radius R from the center) and the end face 13 on the coupling side of the first clip body 11 come into contact with each other (see FIG. 6). In this case, since the center of the pin hole of the first clip portion 1 and the intermediate joint 2 coincides with each other by the pin 5 and B> A, the rounded portion 223 at the tip of the protrusion 2 of the intermediate joint 2 An interference dimension X corresponding to the dimension (B-A) is generated at the contact portion of the first clip main body 11 with the connecting end surface 13. Thereby, the 1st clip part 1 or the intermediate joint 2 generate | occur | produces a support load in the connection part, and can obtain firm support force. In addition, since this strong supporting force is obtained in the wide range shown with a dashed-two dotted line in FIG. 6, when the standing posture as shown in FIG. It can be bent and supported.

掲示物支持具１０によれば、螺子等の別途の部品を使用することなく、互いに連結する第１クリップ部１と中間継手２を相対的に回動させるのみで、連結部の負荷状態を形成することができる。特に、連結部を第１クリップ部１をＡＢＳ樹脂とし、中間継手２をＰＯＭ樹脂とすれば、円滑な回動と強固な支持の両立が可能となり、且つ繰り返し使用においても負荷状態が変わることがない。また、螺子と螺子回しを不要とするため、部材コストを上昇させることがない。なお、掲示物支持具１０は、図１の形態に限定されず、例えば中間継手２が省略され、第２クリップ部３の連結側に、直接、突部２２が形成され、第１クリップ部と第２クリップ部が直接、連結されるものであってもよい。この場合、掲示物支持具の中に、本考案の継手構造体はひとつ存在することになる。 According to the posting object support 10, the load state of the connecting portion is formed only by relatively rotating the first clip portion 1 and the intermediate joint 2 that are connected to each other without using a separate part such as a screw. can do. In particular, if the first clip portion 1 is made of ABS resin and the intermediate joint 2 is made of POM resin, both smooth rotation and strong support can be achieved, and the load state can be changed even after repeated use. Absent. Further, since the screw and screw turning are not required, the member cost is not increased. The posted article support 10 is not limited to the form of FIG. 1, for example, the intermediate joint 2 is omitted, and a protrusion 22 is formed directly on the connection side of the second clip part 3, and the first clip part and The second clip portion may be directly connected. In this case, one joint structure of the present invention is present in the posting support.
