Description

この発明は、綴じ具の固定構造に関し、特に例えば、リングバインダーなどの綴じ具をファイル用表紙などの被固定物に固定する固定構造に関する。   The present invention relates to a fixing structure for a binding tool, and more particularly to a fixing structure for fixing a binding tool such as a ring binder to a fixed object such as a file cover.

ファイル用表紙に綴じ具をとりつけるために従来より金属製鋲が用いられてきたが、近年金属製鋲に変えて、合成樹脂製鋲によって綴じ具をファイル表紙に固定するようになってきた。
例えば、合成樹脂製鋲として、特開２０００−３５２４０７に開示された合成樹脂製鋲などが提案されている。 Conventionally, a metal rivet has been used to attach a binding tool to a file cover. However, in recent years, a binding tool has been fixed to a file cover by a synthetic resin crease instead of a metal lash.
For example, synthetic resin iron making disclosed in JP 2000-352407 has been proposed as synthetic resin iron making.

特開２０００−３５２４０７号公報JP 2000-352407 A

この合成樹脂製の鋲は、破棄処分するときに、ファイル用表紙及び綴じ具より分離できるように構成されているので、分離されたそれぞれをリサイクル用品として再生を可能とするが、アルミニウム、鉄などの金属素材の鋲を利用して表紙にかしめるという従来の方法による綴じ具の固定構造は、ファイル表紙に綴じ具を強固にかしめて固着するため、耐久性に優れている。
しかしながら、合成樹脂製の鋲の場合は、その固着力が金属製の鋲と比較して劣り、また、合成樹脂の特性上、経時変化によってかしめられる前の形状に戻ろうとする方向に変化し、そのかしめ部分にわずかながら緩みが発生する場合がある。
また、ファイル表紙に綴じ具を固着する組み立ての時の利便性から、綴じ具及び表紙のいずれにも、固着する鋲の径より大きな穴をあけてあるので、ファイル表紙と綴じ具にがたつきが生じるおそれがある。 This plastic-made bag is configured so that it can be separated from the file cover and binding tool when discarded, so that each separated can be recycled as recycled goods, but aluminum, iron, etc. The conventional method of fixing a binding tool by caulking to the cover using the metal material rivet is excellent in durability because the binding tool is firmly caulked and fixed to the file cover.
However, in the case of a synthetic resin ridge, its adhesive strength is inferior to that of a metal ridge, and on the characteristics of the synthetic resin, it changes in a direction to return to the shape before being caulked by a change over time, Slight loosening may occur in the caulked portion.

The distance between the tip 205 of the protrusion 201 and the hole edge 207 facing it is cut and raised to a position that is about 0.2 mm longer than the diameter of the pilot hole 209.
Thus, the protrusion 201 for fixing the binding tool 10 to the cover A with the synthetic resin ridge 100 is formed.

固定孔２０及び突起２０１の形状は、前記実施の形態の構造に限らず、この発明の思想に基づき、変更することができる。
例えば、前記実施の形態においては、突起２０１が、固定孔２０の周縁２０３より内側に向けて直線状に切断されてなる切り込みの深奥部において折り曲げられて形成されているが、図１７に示すように、固定孔２０の周縁２０３の孔縁２０７の延長部に沿って、突起２２１をその根元の近傍において折り曲げ、突起２２１全体を立ち上げて形成してもよい。
この突起２２１は、例えば、固定孔２０の周囲をフランジングするバーリング加工機によって形成することができる。
この突起の立ち上げ加工を施すための下穴２２３は、前記実施の形態の真円状下穴ではなく、図１８に示すように異型状すなわち後に折り曲げ加工される突起２２１に対応した突起２２１を下穴２２３の周縁より内側に向けて突き出させた形状に成形し、固定孔２０の周縁２０３に対応した外周形状の胴部２２５を備えた下型２２７を保持部材１６の下面より上型２２９の雌孔２３１内に突き上げて、突起を形成するようにしてもよい。
また、図２０に示すように、突起２３３を固定孔２０の周縁２０３において、二箇所均一な間隔をおいて形成してもよい。 The shapes of the fixing hole 20 and the protrusion 201 are not limited to the structure of the above embodiment, and can be changed based on the idea of the present invention.
For example, in the above-described embodiment, the protrusion 201 is formed by being bent at the deep part of the cut formed by cutting linearly inward from the peripheral edge 203 of the fixing hole 20, as shown in FIG. In addition, the protrusion 221 may be bent near the base along the extended portion of the hole edge 207 of the peripheral edge 203 of the fixing hole 20 and the entire protrusion 221 may be raised.
This protrusion 221 can be formed by, for example, a burring machine that flanges the periphery of the fixing hole 20.
The prepared hole 223 for performing the rising process of the protrusion is not a perfect circular prepared hole in the above-described embodiment, but a protrusion 221 corresponding to the protrusion 221 that is odd-shaped, that is, bent later, as shown in FIG. The lower die 227 is formed in a shape protruding inward from the peripheral edge of the lower hole 223, and the lower die 227 provided with the outer peripheral body portion 225 corresponding to the peripheral edge 203 of the fixing hole 20 is placed on the upper die 229 from the lower surface of the holding member 16. A protrusion may be formed by pushing up into the female hole 231.
In addition, as shown in FIG. 20, the protrusions 233 may be formed on the peripheral edge 203 of the fixing hole 20 at two uniform intervals.

綴じ具１０を表紙Ａに取り付けるには、保持壁２４ａおよび保持壁２４ｂの下端縁と固定部１６ａの下面とを表紙Ａに接合して、固定孔２０，２０に、次に説明する合成樹脂鋲１００により取り付ければよい。
また、前記実施の形態においては、第１の綴杆１２と第２の綴杆１４といったように、２穴タイプの綴じ具について説明したが、綴杆を増やした多穴タイプ、例えば、３穴、４穴、２０穴、２６穴、３０穴といった多くの綴杆を備えた綴じ具とすることができる。 In order to attach the binding tool 10 to the cover A, the lower end edge of the holding wall 24a and the holding wall 24b and the lower surface of the fixing portion 16a are joined to the cover A, and the synthetic resin rods described below are fixed to the fixing holes 20, 20. 100 may be attached.
Moreover, in the said embodiment, although the two-hole type binding tool was demonstrated like the 1st binding rod 12 and the 2nd binding rod 14, the multi-hole type which increased the binding rod, for example, 3 holes It can be set as the binding tool provided with many bindings, such as 4 holes, 20 holes, 26 holes, and 30 holes.

Alternatively, in order to fold the head 114 on either the back surface and separate from the shaft portion 112, the shaft portion 112 is outside the shaft portion 112 when viewed in the axial direction of the shaft portion 112. A groove 116 is formed at a position where the head 114 comes out of the fixing hole 20 into which the shaft portion 112 is inserted.

この合成樹脂鋲１００は、ファイルの表紙Ａと綴じ具１０を固定するものであり、軸部１１２は、被固定物たる綴じ具１０の固定孔２０に挿入され、引っ掛かり用の頭部１１４は、前記軸部１１２の一端に形成された表紙Ａの固定孔Ａ1の周縁に引っ掛かるために形成され、該軸部１１２と引っ掛かり用の頭部１１４とはポリカーボネート等の熱可塑性樹脂をもって一体成形されてなる。 The synthetic resin bag 100 is for fixing the cover A of the file and the binding tool 10, and the shaft portion 112 is inserted into the fixing hole 20 of the binding tool 10, which is an object to be fixed. The shaft portion 112 is formed so as to be caught on the periphery of the fixing hole A 1 of the cover A formed at one end of the shaft portion 112, and the shaft portion 112 and the hooking head portion 114 are integrally formed with a thermoplastic resin such as polycarbonate. Become.

軸部１１２は、引っ掛かり用の頭部１１４の略中央より突設された円柱状で、その外周面は、引っ掛かり用の頭部１１４より先端（下端）に向かうに従ってその径が短くなるテーパー状の中空円筒状である。もっとも、軸部１１２の外周面はテーパー状ではなく、上から下まで同一径の中空円筒状にしてもよい。   The shaft 112 has a cylindrical shape protruding from the approximate center of the hooking head 114, and the outer peripheral surface of the shaft 112 has a tapered shape whose diameter becomes shorter from the hooking head 114 toward the tip (lower end). It is a hollow cylinder. But the outer peripheral surface of the axial part 112 may not be a taper shape, but you may make it the hollow cylinder shape of the same diameter from the top to the bottom.

引っ掛かり用の頭部１１４は、前記軸部１１２と同心円で軸部１１２より大径の円盤状で、周縁部において若干その厚みが漸減するように構成され、引っ掛かり用の頭部１１４の平面部１２０には、前記軸部１１２の外周縁に沿って、平面円形状の第１割り溝１２２が連続して凹設されている。引っ掛かり用の頭部１１４は、軸部１１２の略２倍の直径を有し、その厚さは、その直径の略５分の１である。   The hooking head portion 114 is concentric with the shaft portion 112 and has a disk shape larger in diameter than the shaft portion 112, and is configured such that its thickness gradually decreases at the peripheral portion, and the flat portion 120 of the hooking head portion 114. A flat circular first split groove 122 is continuously provided along the outer peripheral edge of the shaft portion 112. The hooking head 114 has a diameter approximately twice that of the shaft portion 112, and its thickness is approximately one fifth of the diameter.

引っ掛かり用の頭部１１４の外周縁の厚さは、より薄い方が良い。ファイルの表紙Ａの外側に引っ掛かり用の頭部１１４が出る場合、ファイルを収容する棚から出し入れするとき、引っ掛かり用の頭部１１４が隣接するものに引っ掛からないようにするためには、より薄くする方が良い。   The thinner the thickness of the outer peripheral edge of the catching head 114 is, the better. When the hooking head 114 comes out of the cover A of the file, it is made thinner so that the hooking head 114 does not get caught in the adjacent object when the file is taken in or out of the shelf for storing the file. Better.

引っ掛かり用の頭部１１４の底面部１２４には、前記第１割り溝１２２に対応した位置、すなわち、軸部１１２を軸方向に見て軸部１１２の外側の外周縁に沿って適宜な間隔（第１割り溝１２２の幅の略３倍）をあけて４本の平面円弧状の第２割り溝１２６が凹設されている。   The bottom portion 124 of the catching head portion 114 has a suitable distance (ie, a position corresponding to the first split groove 122, that is, along the outer periphery of the shaft portion 112 when the shaft portion 112 is viewed in the axial direction). Four planar arc-shaped second split grooves 126 are formed with a gap of about three times the width of the first split groove 122.

第１割り溝１２２と第２割り溝１２６とは、その一端から他端にわたって略同一幅の断面円弧状の溝をもって構成されている。第１割り溝１２２の幅は、引っ掛かり用の頭部１１４の直径の略２分の１であり、第１割り溝１２２の深さは、引っ掛かり用の頭部１１４の厚さの略４分の１であり、第２割り溝１２６の幅及び深さも略同様である。   The first split groove 122 and the second split groove 126 are configured with a circular arc-shaped groove having substantially the same width from one end to the other end. The width of the first split groove 122 is approximately one half of the diameter of the catching head portion 114, and the depth of the first split groove 122 is approximately four times the thickness of the catch head portion 114. 1 and the width and depth of the second split groove 126 are substantially the same.

第２割り溝１２６の直線状両端縁と引っ掛かり用の頭部１１４の中心とを結ぶ線による弧Ｒ1の中心角は６０°であり、隣接する第２割り溝１２６の直線状両端縁と引っ掛かり用の頭部１１４の中心とを結ぶ線による弧Ｒ2の中心角は３０°である（図２４参照）。 The central angle of the arc R 1 formed by the line connecting the linear both end edges of the second split groove 126 and the center of the catching head 114 is 60 °, and the linear both end edges of the adjacent second split grooves 126 are caught. The central angle of the arc R 2 defined by the line connecting the center of the head 114 is 30 ° (see FIG. 24).

引っ掛かり用の頭部１１４は、第１割り溝１２２と第２割り溝１２６とが対向する部位が、他の領域もより薄い薄肉状に形成されている。   In the hooking head portion 114, a portion where the first split groove 122 and the second split groove 126 face each other is formed in a thin shape that is thinner in other regions.

軸部１１２は、その内部に中空部１３０が形成され、引っ掛かり用の頭部１１４の底面部１２４と略同じ高さ位置において、平面状頂壁部１３２が形成され、該頂壁部１３２より外周に向かうに従って下方（引っ掛かり用の頭部１１４より先端に向かう方向）に傾斜する第１斜壁部１３４が形成され、さらに、該第１斜壁部１３４の下端より下方（引っ掛かり用の頭部１１４より先端に向かう方向）に向かうに従って拡開する第２斜壁部１３６が、軸部１１２の高さの略半分の高さ位置まで形成され、前記第２斜壁部１３６の下端より下方に向けて、上から下まで略同一径の垂直壁部１３８が形成されている。   The shaft portion 112 has a hollow portion 130 formed therein, and a planar top wall portion 132 is formed at substantially the same height position as the bottom surface portion 124 of the catching head portion 114, and the outer periphery of the top wall portion 132 is more peripheral. A first inclined wall portion 134 that is inclined downward (in a direction from the hooking head 114 toward the tip) is formed, and further, the lower portion of the first inclined wall portion 134 is lower (the hooking head 114). A second inclined wall portion 136 that expands toward the tip) is formed to a height position that is substantially half the height of the shaft portion 112, and is directed downward from the lower end of the second inclined wall portion 136. Thus, a vertical wall portion 138 having substantially the same diameter is formed from the top to the bottom.

軸部１１２は、頂壁部１３２より第１斜壁部１３４に至る領域において最も厚く（太く）形成され、第２斜壁部１３６の領域において中間的な厚さ（太さ）に形成され、垂直壁部１３８の領域で最も薄く（細く）形成されている。   The shaft portion 112 is formed to be the thickest (thick) in the region from the top wall portion 132 to the first inclined wall portion 134, and to have an intermediate thickness (thickness) in the region of the second inclined wall portion 136, It is formed to be the thinnest (thinner) in the region of the vertical wall portion 138.

この合成樹脂鋲１００によって、被固定物であるファイルの表紙Ａと綴じ具１０とを固定する場合、ファイルの表紙Ａに穿設された固定孔Ａ1と綴じ具１０に穿設された固定孔２０を合わせ、該固定孔Ａ及び固定孔２０に軸部１１２を貫挿し、反対側の軸部１１２の先端を金型１５０（図２６図示）で常温（冷間）加工して軸部１１２の先端部を潰しカールさせ、綴じ具１０の固定孔２０周辺に密着させて、引っ掛かり用の頭部１１４と協働して表紙Ａに綴じ具１０を固定する。なお、反対側の軸部１１２の先端を加熱溶融して軸部１１２の先端部を潰しカールさせてもよい。 When fixing the cover A of the file, which is an object to be fixed, and the binding tool 10 with the synthetic resin bag 100, the fixing hole A 1 drilled in the cover A of the file and the fixing hole drilled in the binding tool 10. 20, the shaft part 112 is inserted into the fixing hole A and the fixing hole 20, and the tip of the shaft part 112 on the opposite side is processed at room temperature (cold) with a mold 150 (shown in FIG. 26). The front end portion is crushed and curled, brought into close contact with the periphery of the fixing hole 20 of the binding tool 10, and the binding tool 10 is fixed to the cover A in cooperation with the hooking head 114. Alternatively, the tip of the shaft 112 on the opposite side may be heated and melted to crush and curl the tip of the shaft 112.

表紙Ａに綴じ具１０を合成樹脂鋲１００で固定したとき、合成樹脂鋲１００が綴じ具１０の固定孔２０の近傍に形成された突起２０１を覆うように固定され、合成樹脂鋲１００の固定部分たる軸部１１２が、突起２０１に食い込み、合成樹脂鋲１００と綴じ具１０とが充分固着するので、たとえ合成樹脂鋲１００と綴じ具１０の間において緩みが生じたとしても、合成樹脂鋲１００が突起２０１に食い込んだ部分によって、咬持され綴じ具１０ががたつきを生じさせることはない。
特に、綴じ具１０の長手方向の中心線Ｘ3（図１０図示）上に形成された突起２０１ｃは、綴じ具１０の長手方向の移動を規制し、そのがたつきを防ぐ。
そして、綴じ具１０の長手方向の中心線Ｘ3を挟んで左右（幅方向）に振り分けられた突起２０１ａ及び２０１ｂは、綴じ具１０の幅方向の移動を規制し、そのがたつきを防ぐ。 When the binding tool 10 is fixed to the cover A with the synthetic resin ridge 100, the synthetic resin ridge 100 is fixed so as to cover the protrusion 201 formed in the vicinity of the fixing hole 20 of the binding tool 10, and the fixed portion of the synthetic resin ridge 100 is fixed. Since the shaft portion 112 bites into the protrusion 201 and the synthetic resin ridge 100 and the binding tool 10 are sufficiently fixed, even if loosening occurs between the synthetic resin ridge 100 and the binding tool 10, the synthetic resin ridge 100 is The portion biting into the projection 201 is bitten and the binding tool 10 does not rattle.
In particular, the protrusion 201c formed on the longitudinal center line X 3 (shown in FIG. 10) of the binding tool 10 restricts the movement of the binding tool 10 in the longitudinal direction and prevents rattling.
The projections 201a and 201b allocated to the left-right (width direction) across the longitudinal center line X 3 of the binding device 10 restricts the movement in the width direction of the binding device 10 to prevent its rattling.

この合成樹脂鋲１００によって固定された綴じ具１０とファイルの表紙Ａとを分離し破棄する場合、分離された部材を資源として回収し、リサイクル用品として再生するために、それぞれを破壊することなく分離する必要性がある。そのとき、図２８に示すように、ファイルの表紙Ａと綴じ具１０の間に、軸部１１２を捩じ曲げる、例えばドライバーＸの先端をこじ入れ、引っ掛かり用の頭部１１４と閉じ具１０より持ち上げるようにすると、第１割り溝１２２と第２割り溝１２６とが対向する引っ掛かり用の頭部１１４の軸部１１２近傍が最も薄肉状に形成されているため、引っ掛かり用の頭部１１４がその部位で割れて、固定孔２０固定孔Ａ1より軸部１１２を脱嵌することができ、表紙Ａと綴じ具１０とを分離させることができる。 When the binding tool 10 fixed by the synthetic resin basket 100 and the cover A of the file are separated and discarded, the separated members are collected as resources and separated without being destroyed in order to be recycled as recycled goods. There is a need to do. At that time, as shown in FIG. 28, the shaft portion 112 is twisted and bent between the cover A of the file and the binding tool 10, for example, the tip of the driver X is inserted, and the head 114 for catching and the closing tool 10 are used. When lifted, since the vicinity of the shaft portion 112 of the catching head 114 where the first split groove 122 and the second split groove 126 face each other is formed in the thinnest shape, the catching head 114 is The shaft portion 112 can be detached from the fixing hole 20 and the fixing hole A 1 by being broken at the portion, and the cover A and the binding tool 10 can be separated.
