[Fourth Embodiment of Reference Example ]
FIG. 6 is a view showing a fourth embodiment of the fastening structure.
この締結構造は、前述した第１の実施の形態で説明したワッシャー２を用いたもので、この第４の実施の形態では、第３の実施の形態のようなワッシャー嵌合部１１ｅを設けないで、軸部１１の軸方向に沿う面１１ｂ２にワッシャー２を接して設ける。このように、頭部側にワッシャー２を介在させ傾斜面１２ａを介して被締結部材３を押圧する。リベット１の軸部１１と、被締結部材挿通孔３１及び基材挿通孔４１との間に隙間があるため、カラー５を介在させており、第１の実施の形態と同様に構成は、同じ符号を付して説明を省略する。 This fastening structure uses the washer 2 described in the first embodiment. In the fourth embodiment, the washer fitting portion 11e as in the third embodiment is not provided. Thus, the washer 2 is provided in contact with the surface 11b2 along the axial direction of the shaft portion 11. In this way, the member to be fastened 3 is pressed via the inclined surface 12a with the washer 2 interposed on the head side. Since there is a gap between the shaft portion 11 of the rivet 1 and the fastening member insertion hole 31 and the base material insertion hole 41, the collar 5 is interposed, and the configuration is the same as in the first embodiment. The reference numerals are attached and the description is omitted.
この第４の実施の形態では、リベット１の頭部１２の径Ｌ２０が、被締結部材挿通孔３１の径Ｌ３１及び基材挿通孔４１の径Ｌ４１よりも小さく形成されている。また、ワッシャー２は、形状回復温度に加熱すると形状回復してその内径Ｌ１０が頭部１２の径Ｌ２０よりも大きくなるように形状記憶された形状記憶材料からなっている。 In the fourth embodiment, the diameter L20 of the head 12 of the rivet 1 is formed to be smaller than the diameter L31 of the fastening member insertion hole 31 and the diameter L41 of the base material insertion hole 41. The washer 2 is made of a shape memory material whose shape is restored when heated to the shape recovery temperature and whose inner diameter L10 is larger than the diameter L20 of the head 12.
この第４の実施の形態では、リベット１の軸部１１と、被締結部材挿通孔３１及び基材挿通孔４１との間に隙間があるため、カラー５を介在させており、このカラー５によったことで隙間がなくなり、被締結部材３及び基材４が位置ずれを生じることなく、しかも確実にかしめて締結することができる。 In the fourth embodiment, since there is a gap between the shaft portion 11 of the rivet 1 and the member insertion hole 31 and the base material insertion hole 41, the collar 5 is interposed. As a result, there is no gap, and the fastened member 3 and the base material 4 can be securely crimped without being displaced.
この第４の実施の形態では、図６（ａ）に示すように、被締結部材３と基材４とを締結した状態で、ワッシャー２を形状回復温度まで加熱すると、図６（ｂ）に示すように、形状回復してその内径Ｌ１０がリベット１の頭部１２の径Ｌ２０よりも大きくなり、リベット１の頭部１２が簡単に被締結部材挿通孔３１及び基材挿通孔４１から抜け、 図６（ｃ）に示すように、リベット１、ワッシャー２、被締結部材３、基材４を分離して容易に解体することができるが、カラー５はリベット１に組み付けられている。
［第５の実施の形態］
図７は締結構造の第５の実施の形態を示す図である。
In the fourth embodiment, as shown in FIG. 6A, when the washer 2 is heated to the shape recovery temperature with the fastened member 3 and the base material 4 fastened, the state shown in FIG. As shown, the shape recovers and its inner diameter L10 becomes larger than the diameter L20 of the head 12 of the rivet 1, so that the head 12 of the rivet 1 can be easily removed from the member insertion hole 31 and the base material insertion hole 41, As shown in FIG. 6C, the rivet 1, washer 2, fastened member 3, and base material 4 can be separated and easily disassembled, but the collar 5 is assembled to the rivet 1.
[Fifth Embodiment]
FIG. 7 is a view showing a fifth embodiment of a fastening structure.
この締結構造は、前述した第１の実施の形態で説明したワッシャー２を用いたもので、この第５の実施の形態では、かしめた先端部側にワッシャー２を介在させて基材４を押圧し、リベット１の軸部１１と、被締結部材挿通孔３１との間には隙間がないが、リベット１の軸部１１と、基材挿通孔４１との間に隙間があるため、カラー５を介在させており、第１の実施の形態と同様に構成は、同じ符号を付して説明を省略する。 This fastening structure uses the washer 2 described in the first embodiment, and in this fifth embodiment, the base member 4 is pressed by interposing the washer 2 on the crimped tip side. However, there is no gap between the shaft portion 11 of the rivet 1 and the fastening member insertion hole 31, but there is a gap between the shaft portion 11 of the rivet 1 and the base material insertion hole 41. In the same manner as in the first embodiment, the same reference numerals are given to the configuration, and description thereof is omitted.
この第５の実施の形態では、ワッシャー２が形状回復温度に加熱すると形状回復してその内径Ｌ１０がかしめた先端部１１ａの外径Ｌ１１よりも大きくなるように形状記憶された形状記憶材料からなり、かしめた先端部１１ａの外径Ｌ１１は、被締結部材挿通孔３１の径Ｌ２５より大きく、かつ基材挿通孔４１の径Ｌ４１よりも小さく形成されている。 In the fifth embodiment, the shape memory material is stored so that the shape is recovered when the washer 2 is heated to the shape recovery temperature and the inner diameter L10 of the washer 2 is larger than the outer diameter L11 of the crimped tip 11a. The outer diameter L11 of the crimped tip end portion 11a is formed larger than the diameter L25 of the fastening member insertion hole 31 and smaller than the diameter L41 of the base material insertion hole 41.
この第５の実施の形態では、リベット１の軸部１１と、基材挿通孔４１との間に隙間があるため、カラー５を介在させており、このカラー５によって隙間がなくなり、基材４が位置ずれを生じることなく、しかも確実にかしめて締結することができる。 In the fifth embodiment, since there is a gap between the shaft portion 11 of the rivet 1 and the base material insertion hole 41, the collar 5 is interposed. Can be securely crimped without causing any displacement.
また、この第５の実施の形態では、基材挿通孔４１にカラー５を挿入することで、カラー５の内径Ｌ５１と、被締結部材３に形成された被締結部材挿通孔３１の径Ｌ３１が同じ径であり、リベット１の軸部１１を第１の実施の形態より小さい径Ｌ２５に形成できる。したがって、リベット１の頭部１２と被締結部材３との接する面積を大きくすることができ、その分被締結部材３と基材４との締結力を増加させることができる。 In the fifth embodiment, by inserting the collar 5 into the base material insertion hole 41, the inner diameter L51 of the collar 5 and the diameter L31 of the member insertion hole 31 to be fastened formed in the member 3 to be fastened are obtained. The shaft 11 of the rivet 1 can be formed to have a diameter L25 smaller than that of the first embodiment. Therefore, the contact area between the head 12 of the rivet 1 and the fastened member 3 can be increased, and the fastening force between the fastened member 3 and the base material 4 can be increased accordingly.
このような締結構造とすることで、図７（ａ）に示すように、リベット１の軸部１１を、被締結部材３に形成された被締結部材挿通孔３１と、基材４に形成された基材挿通孔４１に挿入されたカラー５に挿通させ、軸部１１の頭部１２を、被締結部材３に圧接するように軸部１１の先端部１１ａを外側へ向けてかしめてワッシャー２を介してカラー５及び基材４に押圧することによって被締結部材３と基材４とをばらつきなく高精度に締結することができる。 By adopting such a fastening structure, as shown in FIG. 7A, the shaft portion 11 of the rivet 1 is formed in the fastened member insertion hole 31 formed in the fastened member 3 and the base material 4. The washer 2 is caulked with the tip portion 11a of the shaft portion 11 facing outward so that the head portion 12 of the shaft portion 11 is pressed into contact with the member 3 to be fastened. By pressing the collar 5 and the base material 4 through the fastening member 3, the fastened member 3 and the base material 4 can be fastened with high accuracy without variation.
図７（ａ）に示すように、被締結部材３と基材４とを締結した状態で、ワッシャー２を形状回復温度まで加熱すると、図７（ｂ）に示すように、形状回復してその内径Ｌ１０がリベット１のかしめた先端部１１ａの外径Ｌ１１よりも大きくなるが、かしめた先端部１１ａの外径Ｌ１１は、カラー５の内径Ｌ５１より大きく、かつ基材挿通孔４１の径Ｌ４１よりも小さく形成されているから、リベット１、カラー５、被締結部材３が基材挿通孔４１から抜け、リベット１、カラー５及び被締結部材３からワッシャー２、基材４が別々になって容易に被締結部材３と基材４を解体することができる。
［第６の実施の形態］
図８は文房具の実施形の態を示す斜視図である。この実施の形態の文房具60は、バインダーを示しており、前述した第１乃至第５の実施の形態の締結構造が適用できる。バインダーの文房具60では、基材4としてボール紙が用いられ、被締結部材３としてクリップが用いられ、このボール紙とクリップとがリベット１を用いた前述した第１乃至第５の実施の形態の締結構造で締結されている。したがって、不要になった文房具６０のバインダーは、素人でもワッシャーを形状回復温度に加熱して容易に締結構造のボール紙とクリップを解体することができる。
As shown in FIG. 7 (a), when the washer 2 is heated to the shape recovery temperature in a state where the fastened member 3 and the substrate 4 are fastened, the shape is recovered as shown in FIG. 7 (b). The inner diameter L10 is larger than the outer diameter L11 of the crimped tip 11a of the rivet 1, but the outer diameter L11 of the crimped tip 11a is larger than the inner diameter L51 of the collar 5 and larger than the diameter L41 of the base material insertion hole 41. Since the rivet 1, the collar 5 and the fastened member 3 are removed from the base material insertion hole 41, the washer 2 and the base material 4 are easily separated from the rivet 1, the collar 5 and the fastened member 3 easily. The to-be-fastened member 3 and the base material 4 can be disassembled.
