Description

この発明は、綴じ具に関し、特にたとえば、操作レバーを操作して書類などの被綴じ物を挟み込んでファイル・バインダー類に綴じるための綴じ具に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding tool, and more particularly to, for example, a binding tool for operating a control lever to insert a binding object such as a document into a file binder.

従来の綴じ具として、図１８及び１９に示すような綴じ具がある。図１８は、綴じ具の一例を示す平面図であり、図１９はその断面図解図である。綴じ具１は、板状の基板２を含む。基板２の幅方向の一端側には、垂直壁３が形成される。また、垂直壁３と対向するようにして、基板２上に、枢支壁４および起立壁５が形成される。枢支壁４には、綴じ部材６が取り付けられる。綴じ部材６は、幅方向の中間部において回動可能に枢支壁４に取り付けられ、幅方向の一端側が垂直壁３側に配置され、他端側が垂直壁３の反対側に配置される。綴じ部材６は、上側に膨らむように湾曲して形成され、幅方向の他端側において、基板２に向かって徐々に下がっていくように形成される。
さらに、垂直壁３と起立壁５との間に枢支軸が掛け渡され、この枢支軸にバネ部材７および操作レバー８が取り付けられる。バネ部材７の一端側は操作レバー８の内側に延びるように形成され、操作レバー８に固定される。また、バネ部材８の他端側は、垂直壁３と枢支壁４との間において綴じ部材６の幅方向の一端側に延びるように形成され、綴じ部材６の下面に当接される。そして、操作レバー８を操作することにより、バネ部材７の他端側が垂直壁３側の綴じ部材６を持ち上げ、綴じ部材６の他端側が基板２の面に押し当てられる。この綴じ部材６と基板２との間に書類などを挟み込むことによって、書類が綴じ込まれる（特許文献１参照）。
しかしながら、このような従来の綴じ具では、綴じ具に挟み込まれた書類などが引っ張られたとき、書類を押える綴じ部材の端部が、書類の引っ張り方向に傾斜しているため、書類の引っ張り力に対する抵抗力が弱く、綴じ具から書類が外れやすいという問題がある。
それゆえに、綴じられた書類などが引っ張られても、容易に外れたりしない綴じ部材を提案した（特許文献２参照）。
また、従来、ファイル・バインダー類に用箋等の被綴じ物を穴を開けずに綴じる綴じ具として、Ｚ式金具が一般的である（特許文献３参照）。 As a conventional binding tool, there is a binding tool as shown in FIGS. FIG. 18 is a plan view showing an example of a binding tool, and FIG. 19 is a cross-sectional view thereof. The binding tool 1 includes a plate-like substrate 2. A vertical wall 3 is formed on one end side in the width direction of the substrate 2. A pivot wall 4 and an upright wall 5 are formed on the substrate 2 so as to face the vertical wall 3. A binding member 6 is attached to the pivot wall 4. The binding member 6 is attached to the pivot wall 4 so as to be rotatable at an intermediate portion in the width direction, and one end side in the width direction is disposed on the vertical wall 3 side, and the other end side is disposed on the opposite side of the vertical wall 3. The binding member 6 is formed to bend so as to swell upward, and is formed to gradually lower toward the substrate 2 at the other end in the width direction.
Further, a pivot shaft is spanned between the vertical wall 3 and the upright wall 5, and the spring member 7 and the operation lever 8 are attached to the pivot shaft. One end side of the spring member 7 is formed so as to extend inside the operation lever 8 and is fixed to the operation lever 8. The other end side of the spring member 8 is formed between the vertical wall 3 and the pivot wall 4 so as to extend to one end side in the width direction of the binding member 6, and is in contact with the lower surface of the binding member 6. Then, by operating the operation lever 8, the other end side of the spring member 7 lifts the binding member 6 on the vertical wall 3 side, and the other end side of the binding member 6 is pressed against the surface of the substrate 2. The document is bound by sandwiching the document or the like between the binding member 6 and the substrate 2 (see Patent Document 1).
However, in such a conventional binding tool, when the document sandwiched between the binding tools is pulled, the end of the binding member that holds the document is inclined in the document pulling direction. There is a problem that the resistance to the paper is weak and the document is easily detached from the binding tool.
Therefore, a binding member has been proposed that does not easily come off when a bound document or the like is pulled (see Patent Document 2).
Conventionally, a Z-type fitting is generally used as a binding tool for binding a binding object such as a note on a file / binder without opening a hole (see Patent Document 3).

ところが、特許文献３の綴じ具の捩りばねからなるばね部材６は、操作レバー４を軸受板３側に付勢する力も強い。そのために、ロックを解除するには、操作レバー４の自由端を押し下げ、その後操作レバー４を軸受板３とは逆方向に水平移動させて回動させるとき、捩りばねによる力が解除する方向とは反対方向に作用するので、反対方向の力を打ち消すために強い力で操作レバー４を軸受板３とは離れる方向に押す必要性があり、操作性が悪い。
それゆえに、この発明の主たる目的は、綴じられた書類などが引っ張られても容易に外れたりせず、操作部材に不要な力がかかることなく操作性の良い綴じ具を提供することである。 However, the spring member 6 formed of the torsion spring of the binding tool of Patent Document 3 has a strong force for urging the operation lever 4 toward the bearing plate 3. Therefore, in order to release the lock, when the free end of the operation lever 4 is pushed down and then the operation lever 4 is horizontally moved in the direction opposite to the bearing plate 3 and rotated, the force by the torsion spring is released. Since it acts in the opposite direction, it is necessary to push the operating lever 4 away from the bearing plate 3 with a strong force in order to cancel the force in the opposite direction, and the operability is poor.
SUMMARY OF THE INVENTION Therefore, a main object of the present invention is to provide a binding tool that does not easily come off even when a bound document or the like is pulled, and that has an excellent operability without applying unnecessary force to an operation member.

The shaft 46 and the winding portion 50 a of the spring member 50 are bridged between the bearing portion 24 and the bearing portion 38 so as to cross the bearing portion 24.

ばね部材５０の第２端部５０ｂは、巻線部５０ａの軸受板２４側でその後側の上端より手前側に直線状に延び、その先端が外力を受けないときは、その先端が手前側に斜め上方に向けて延びるように形成されている。

It is formed to extend obliquely upward.
The first end portion 50c includes a rising portion 50d that extends from the lower end of the front side of the winding portion 50a to the opposite side of the bearing plate 24 on the bearing portion 38 side, and is substantially L-shaped when receiving no external force. In this way, a bridging portion 50e extends obliquely upward from the upper end of the rising portion 50d that extends upward, and a locking portion 50f that is bent in the horizontal direction protrudes from the free end side of the bridging portion 50e.
The first end portion 50c where the external force does not act and the second end portion 50b (particularly the rising portion 50b) where the external force does not act substantially extend in a direction in which the first end portion 50c and the second end portion 50b do not act. It is formed in an eight shape.

基板２２は、軸４６の一端を軸支する軸固定部たる軸受板２４と、前記軸受板２４の貫通孔２６より向こう側にわずかにずれた位置に形成され、軸４６の他端を軸支する軸固定部たる軸受部３８とを有する。
軸受板２４の貫通孔２６と軸受部３８の貫通孔４０とに架け渡されて固定された軸４６は、その綴じ部材７０側である軸受部３８側の方が、軸４６の軸受板２４側を中心にして操作レバー６０の自由端より離れる方向に水平面上において回転した位置において、軸受部３８の貫通孔４０に固定されている。
ばね部材５０は、軸固定部たる軸受板２４と軸受部３８との間において、巻線部５０ａが軸４６の軸回りにおいて基板２２と略平行に装着され、前記外力が作用しない第２端部５０ｂは、操作レバー６０の長手方向と略平行に操作レバー６０に固定されている。
すなわち、前記外力が作用しない第２端部５０ｂは、被綴じ物Ｘを押圧するロック状態とロックを解除する状態とに操作レバー６０を回動させる方向、すなわち操作レバー６０が回動する軌道面に沿って、操作レバー６０に固定されている。したがって、ばね部材５０は、不用な干渉なくスムーズに動くことができ、操作レバー６０の上昇及び下降等の動きもスムーズになる。 The substrate 22 is formed at a position slightly shifted away from the through hole 26 of the bearing plate 24, which is a shaft fixing portion that supports one end of the shaft 46, and the other end of the shaft 46 is supported by the shaft. And a bearing portion 38 as a shaft fixing portion.
The shaft 46 that is bridged and fixed between the through hole 26 of the bearing plate 24 and the through hole 40 of the bearing portion 38 has a bearing portion 38 side that is the binding member 70 side, and the shaft 46 side of the shaft 46. Is fixed to the through hole 40 of the bearing portion 38 at a position rotated on the horizontal plane in a direction away from the free end of the operation lever 60.
The spring member 50 has a second end portion between the bearing plate 24 and the bearing portion 38 as a shaft fixing portion, in which the winding portion 50a is mounted substantially parallel to the substrate 22 around the shaft 46, and the external force does not act. 50 b is fixed to the operation lever 60 substantially parallel to the longitudinal direction of the operation lever 60.
That is, the second end portion 50b to which the external force does not act is the direction in which the operation lever 60 is rotated between the locked state in which the binding object X is pressed and the unlocked state, that is, the track surface on which the operation lever 60 rotates. And is fixed to the operation lever 60. Therefore, the spring member 50 can move smoothly without unnecessary interference, and the movement of the operation lever 60 such as raising and lowering becomes smooth.

巻線部５０ａの内径は、軸４６の外径と略同じで、殆んどクリアランスがない状態において、軸４６の外周面上に巻線部５０ａが巻装されている。
すなわち、巻線部５０ａは、操作レバー６０の長手方向とは斜めに交差するように第２端部５０ｂ側から第１端部５０ｃ側に向けて延び、ばね部材５０の第１端部５０ｃの側が、第２端部５０ｂの側より向こう側の位置において、基板２２に固定されている。
ばね部材５０に外力が作用しないとき、第２端部５０ｂは、操作レバー６０の自由端を軸４６を枢軸として押し上げるように形成され、第１端部５０ｃは、綴じ部材７０を基板２２の表面に接近するように形成されている。
ばね部材５０は、第２端部５０ｂが操作レバー６０の長手方向と略平行に操作レバー６０に固定されているので、操作レバー６０を倒伏位置に向けて押し下げるとき、軸受板２４と略平行な方向すなわち垂直方向に向けて押し下げ、軸受板２４に形成されたロック用固定部たる固定用凸部２８に係止させることができる。 The inner diameter of the winding portion 50a is substantially the same as the outer diameter of the shaft 46, and the winding portion 50a is wound on the outer peripheral surface of the shaft 46 in a state where there is almost no clearance.
That is, the winding portion 50 a extends from the second end portion 50 b side toward the first end portion 50 c side so as to obliquely intersect the longitudinal direction of the operation lever 60, and the first end portion 50 c of the spring member 50. The side is fixed to the substrate 22 at a position farther from the second end 50b side.
When no external force acts on the spring member 50, the second end 50b is formed so as to push up the free end of the operation lever 60 with the shaft 46 as a pivot, and the first end 50c pushes the binding member 70 to the surface of the substrate 22. It is formed to approach.
Since the second end portion 50b of the spring member 50 is fixed to the operation lever 60 substantially parallel to the longitudinal direction of the operation lever 60, the spring member 50 is substantially parallel to the bearing plate 24 when the operation lever 60 is pushed down toward the lying down position. It can be pushed down in the direction, that is, in the vertical direction, and can be locked to a fixing convex portion 28 that is a locking fixing portion formed on the bearing plate 24.

操作レバー６０は、金属板などによって長尺状に形成され、その強度を高めるために、横断面略Ｌ字状または横断面略Ｕ字状に形成され、軸受板２４側の第１垂直側壁６０ａと、第１垂直側壁６０ａと一定の間隔をおいて平行に形成された第２垂直側壁６０ｂとを備える。
操作レバー６０の長手方向の一端側（向こう側）における第１垂直側壁６０ａには、円形の貫通孔６２が形成される。そして、軸４６が、操作レバー６０の貫通孔６２と第１垂直側壁６０ａの内側に配設されたばね部材５０の巻線部５０ａとに挿通するようにして、軸受板２４および軸受部３８に取り付けられる。
ばね部材５０の第２端部５０ｂは、操作レバー６０の内側に沿って配置され、操作レバー６０の第１垂直側壁６０ａの一部を内側に折り曲げた折曲片６４によって固定される。
さらに、操作レバー６０の第１垂直側壁６０ａには、操作レバー６０を枢支する軸４６を取り付ける貫通孔６２とは操作レバー６０の自由端側（手前側）に離れた位置において、軸受板２４の固定用凸部２８に対応する位置に矩形の係止貫通孔６６が形成される。この係止貫通孔６６に固定用凸部２８が嵌め込まれ、係止貫通孔６６の下縁６８が固定用凸部２８の下部に係止されることにより、操作レバー６０が軸受板２４にロック固定される。 The operation lever 60 is formed in a long shape by a metal plate or the like, and is formed in a substantially L-shaped cross section or a substantially U-shaped cross section in order to increase its strength, and the first vertical side wall 60a on the bearing plate 24 side. And a first vertical side wall 60a and a second vertical side wall 60b formed in parallel with a certain distance.
A circular through hole 62 is formed in the first vertical side wall 60 a on one end side (the other side) in the longitudinal direction of the operation lever 60. The shaft 46 is attached to the bearing plate 24 and the bearing portion 38 so as to pass through the through hole 62 of the operation lever 60 and the winding portion 50a of the spring member 50 disposed inside the first vertical side wall 60a. It is done.
The second end portion 50b of the spring member 50 is disposed along the inner side of the operation lever 60 and is fixed by a bent piece 64 obtained by bending a part of the first vertical side wall 60a of the operation lever 60 inward.
Further, in the first vertical side wall 60 a of the operation lever 60, the bearing plate 24 is positioned away from the through hole 62 for attaching the shaft 46 that pivotally supports the operation lever 60 to the free end side (front side) of the operation lever 60. A rectangular locking through-hole 66 is formed at a position corresponding to the fixing projection 28. The fixing projection 28 is fitted into the locking through hole 66, and the lower edge 68 of the locking through hole 66 is locked to the lower portion of the fixing projection 28, so that the operation lever 60 is locked to the bearing plate 24. Fixed.

前記操作レバー６０は、ロック用固定部が、係止貫通孔６６の孔縁であって、ロック状態を維持するためにばね部材５０により付勢されて軸受板２４のロック用固定部たる固定用凸部２８に係止される係止貫通孔６６の下縁６８に形成され、且つ、ロックを解除するために案内する案内部が、係止貫通孔６６の孔縁であって、ロックを解除する方向とは反対側の係止貫通孔６６の上縁６６ａに形成される。
係止貫通孔６６は、下縁６８の近傍が操作レバー６０を固定用凸部２８から外す方向に向けて突き出され、上縁６６ａと下縁６８とが横方向において、その位置がずれている。すなわち、下縁６８は、操作レバー６０のロックを解除するとき、操作レバー６０の係止貫通孔６６を固定用凸部２８から外す方向に向いて、その位置がはずれており、下縁６８は、上縁６６ａから、操作レバー６０の係止貫通孔６６を固定用凸部２８から外す方向に向けてずれている。
上縁６６ａの位置から下縁６８がずれる距離は、係止貫通孔６６の固定用凸部２８からロック（係止）を解除するときに、係止貫通孔６６の上縁６６ａを固定用凸部２８の最頂部に接しながら滑り降ろして、斜め方向に移動させて固定用凸部２８の最も内縁部（軸受部２４の起立面部より離れる側）よりわずかに外れる方向に移動したとき、斜め下方向に降ろす力を解除すれば、ばね部材５０の弾発力により係止貫通孔６６の下縁６８が固定用凸部２８の内側（軸受部２４の起立面部より離れる側）先端に引っ掛ることなく、操作レバー６０が上昇するように設定されている。 In the operation lever 60, the lock fixing portion is a hole edge of the locking through-hole 66, and is biased by the spring member 50 to maintain the locked state, and is used as the lock fixing portion of the bearing plate 24 . The guide portion that is formed on the lower edge 68 of the locking through hole 66 that is locked to the convex portion 28 and that is guided to release the lock is the hole edge of the locking through hole 66, and the lock is released. It is formed on the upper edge 66a of the locking through-hole 66 on the opposite side to the direction of making.
The locking through-hole 66 protrudes in the vicinity of the lower edge 68 in a direction to remove the operation lever 60 from the fixing convex portion 28, and the upper edge 66a and the lower edge 68 are shifted in the lateral direction. . That is, the lower edge 68, when unlocking the operating lever 60, facing in a direction to disengage the locking through-holes 66 of the operation lever 60 from the convex fixing part 28, and out its position, the lower edge 68 The locking through hole 66 of the operation lever 60 is displaced from the upper edge 66a in a direction to remove it from the fixing convex portion 28.
The distance from which the lower edge 68 is displaced from the position of the upper edge 66a is such that the upper edge 66a of the locking through hole 66 is fixed to the fixing protrusion when the locking (locking) is released from the fixing protrusion 28 of the locking through hole 66. When it slides down while touching the topmost part of the part 28 and moves in an oblique direction and moves in a direction slightly deviating from the innermost edge part of the fixing convex part 28 (the side away from the rising surface part of the bearing part 24), If the force of lowering in the direction is released, the lower edge 68 of the locking through-hole 66 is hooked on the inner tip of the fixing convex portion 28 (the side away from the standing surface portion of the bearing portion 24) by the elastic force of the spring member 50. The operation lever 60 is set to be raised.

また、操作レバー６０の長手方向の他端側（手前側）は、幅広の操作部６０ｃが形成され、指で操作しやすくなっている。
固定用凸部２８は、操作レバー６０の第１垂直側壁６０ａ及び第２垂直側壁６０ｂが基板２２の表面に達する前に、操作レバー６０の係止貫通孔６６から外れる幅を有している。
なお、操作レバー６０の第１垂直側壁６０ａの高さを比較的高くすれば、操作レバー６０のロック解除のときの移動距離を長くとることができ、操作性を増すことができる。 Further, a wide operation portion 60c is formed on the other end side (near side) in the longitudinal direction of the operation lever 60 so that it can be easily operated with a finger.
The fixing convex portion 28 has a width that is removed from the locking through hole 66 of the operation lever 60 before the first vertical side wall 60 a and the second vertical side wall 60 b of the operation lever 60 reach the surface of the substrate 22.
If the height of the first vertical side wall 60a of the operation lever 60 is made relatively high, the movement distance when unlocking the operation lever 60 can be increased, and the operability can be increased.

前記操作レバー６０は、軸受板２４に固定する部位である固定部たる第１垂直側壁６０ａを備えており、軸受板２４は、前記操作レバー６０の第１垂直側壁６０ａと接して操作レバー６０を固定する部位である操作部材固定部たる貫通孔２６の下部周辺が、操作レバー６０が取り付けられる方向に向けて膨出されてスペーサー２６ａを形成する。
すなわち、軸４６の固定部（軸固定部）たる貫通孔２６の周辺は、操作レバー６０側に向けて半円環状に打ち出し膨出されたスペーサー２６ａが形成されている。そして、スペーサー２６ａの突出分だけ軸受板２４の内面と操作レバー６０の第１垂直側壁６０ａの外面との間に間隔があき、操作レバー６０をロック状態とロックを解除する状態とに回動させるとき、ばね部材５０の不要な力が操作レバー６０にかかることなく操作レバー６０が軸受板２４に擦れることがない。
この実施の形態においては、スペーサー２６ａが軸受板２４に形成されたが、スペーサー２６ａは、操作レバー６０側に形成してもよく、また軸受板２４と操作レバー６０の両方に形成してもよい。例えば、操作レバー６０の第１垂直側壁６０ａの周辺を、軸受板２４側に向けて円環状に膨出されたスペーサーを形成するようにしてもよい。 The operation lever 60 includes a first vertical side wall 60 a that is a fixing portion that is a portion fixed to the bearing plate 24, and the bearing plate 24 contacts the first vertical side wall 60 a of the operation lever 60 and moves the operation lever 60. The periphery of the lower portion of the through-hole 26 that is the operation member fixing portion that is a fixing portion is bulged in a direction in which the operation lever 60 is attached to form the spacer 26a.
That is, a spacer 26a is formed around the through hole 26, which is a fixing portion (shaft fixing portion) of the shaft 46, and is swelled in a semicircular shape toward the operation lever 60 side. Then, there is a gap between the inner surface of the bearing plate 24 and the outer surface of the first vertical side wall 60a of the operation lever 60 by the amount of protrusion of the spacer 26a, and the operation lever 60 is rotated between the locked state and the unlocked state. At this time, the operation lever 60 is not rubbed against the bearing plate 24 without unnecessary force of the spring member 50 being applied to the operation lever 60.
In this embodiment, the spacer 26a is formed on the bearing plate 24. However, the spacer 26a may be formed on the operation lever 60 side, or may be formed on both the bearing plate 24 and the operation lever 60. . For example, a spacer bulging in an annular shape toward the bearing plate 24 may be formed around the first vertical side wall 60a of the operation lever 60.

さらに、基板２２上には、平面視略長方形状の綴じ部材７０が、基板２２の長手方向に延びて軸受板２４と平行に取り付けられ、軸受板２４とは反対側の長手端縁が基板２２の表面に接近離間するように形成される。綴じ部材７０は、たとえば１枚の金属板によって形成される。綴じ部材７０は、たとえば枢支部３０と枢支部３４との距離に略等しい長さを有し、幅方向において上方に向けて膨らむように屈曲する形状（断面略Ｌ字状）に形成される。
そして、綴じ部材７０の幅方向の軸受板２４側において、その長手方向の両側に突出する枢軸たる突出片７２が形成される。これらの突出片７２が、枢軸受けたる枢支部３０の貫通孔３２および枢軸受けたる枢支部３４の貫通孔３６に嵌め込まれる。手前側の枢支部３４の貫通孔３６は、向こう側の枢支部３０の貫通孔３２と比較して、基板２２からの高さが低くなるように形成され、向こう側の貫通孔３２に枢支された綴じ部材７０の向こう側の突出片７２ａの方が、手前側の貫通孔３６に枢支された綴じ部材７０の手前側の突出片７２ｂの方より高い位置で枢支されている。 Further, on the substrate 22, a binding member 70 having a substantially rectangular shape in a plan view extends in the longitudinal direction of the substrate 22 and is attached in parallel to the bearing plate 24, and a longitudinal edge opposite to the bearing plate 24 has a longitudinal edge on the substrate 22. It is formed so as to approach and separate from the surface. The binding member 70 is formed of, for example, a single metal plate. The binding member 70 has a length substantially equal to the distance between the pivot portion 30 and the pivot portion 34, for example, and is formed in a shape that is bent so as to bulge upward in the width direction (substantially L-shaped in cross section).
Then, on the bearing plate 24 side in the width direction of the binding member 70, protruding pieces 72 serving as pivots protruding on both sides in the longitudinal direction are formed. These protruding pieces 72 are fitted into the through hole 32 of the pivotal support portion 30 that is a pivotal bearing and the through hole 36 of the pivotal support portion 34 that is a pivotal bearing. The through hole 36 of the front pivot part 34 is formed to have a lower height from the substrate 22 than the through hole 32 of the far pivot part 30, and is pivotally supported by the far side through hole 32. The protruding piece 72a on the opposite side of the binding member 70 is pivotally supported at a position higher than the protruding piece 72b on the near side of the binding member 70 pivotally supported on the through hole 36 on the near side.

したがって、綴じ部材７０は、２つの突出片７２を結ぶ線を回転中心として回動可能となっている。
そして、操作レバー６０の手前側の自由端を押さえてロックするとき、綴じ部材７０の手前側の突出片７２ｂが低いので、ばね部材５０の係止部５０ｆが綴じ部材７０の折曲部７４を押える位置（綴じ部材７０の長手方向における中央より向こう側）より遠い部位から被綴じ物Ｘを押さえ始めて、被綴じ物Ｘにかかる押える力のバランスが向こう側と手前側と均等となる。 Therefore, the binding member 70 can be rotated about the line connecting the two protruding pieces 72 as the rotation center.
When the front side free end of the operation lever 60 is pressed and locked, the front projecting piece 72b of the binding member 70 is low, so that the locking portion 50f of the spring member 50 causes the bent portion 74 of the binding member 70 to be bent. The binding object X starts to be pressed from a position farther from the pressing position (the far side from the center in the longitudinal direction of the binding member 70), and the pressing force applied to the binding object X is balanced between the far side and the near side.

なお、突出片７２の強度を高め、貫通孔３２，３６内で突出片７２が回転しやすいように、突出片７２は幅方向に屈曲するように形成される。このように、綴じ部材７０から突出する突出片７２を枢支部３０，３４の貫通孔３２，３６に嵌め込むことにより、別部品たる回転軸などを用いて綴じ部材７０を回動可能に保持する場合に比べて、部品数を少なくすることができる。 The protruding piece 72 is formed to bend in the width direction so that the strength of the protruding piece 72 is increased and the protruding piece 72 can easily rotate in the through holes 32 and 36. In this way, by fitting the protruding piece 72 protruding from the binding member 70 into the through holes 32 and 36 of the pivotal support portions 30 and 34, the binding member 70 is rotatably held using a rotating shaft or the like which is a separate part. Compared to the case, the number of parts can be reduced.

また、綴じ部材７０の幅方向における軸受板２４の反対側は、上述の回転中心側（突出片７２側）に向かって水平面に対して略２０°折り曲げられ、折曲部７４が形成される。
折曲部７４は、綴じ部材７０の手前側端縁より向こう側端縁に至るまで連続して形成される。さらに、折曲部７４の先端側が基板２２側に向かって折り曲げられ、書類などの被綴じ物Ｘを押えるための押圧部７６が形成される。
押圧部７６は、折曲部７４の手前側端縁より向こう側端縁に至るまで連続して形成される。押圧部７６は、その自由端に形成された被綴じ物Ｘに接地する接地領域が向こう側の接地部７６ａと手前側の接地部７６ｂとに分かれており、向こう側の接地部７６ａの方が手前側の接地部７６ｂより短い接地面積となるように形成されている。
押圧部７６は、綴じ部材７０が基板２２側に倒伏した閉じた状態のときに、折曲部７４から基板２２に向かうにしたがって、綴じ部材７０の回転中心側に傾斜するように形成される。したがって、折曲部７４と押圧部７６とは、略Ｌ字状に連設される。この押圧部７６によって、書類などの被綴じ物Ｘが１本の直線状に押圧される。ここで、綴じ部材７０が基板２２側に閉じた状態のときに、折曲部７４は綴じ部材７０の端部側から綴じ部材７０の内側に向けて上昇する。 Further, the opposite side of the bearing plate 24 in the width direction of the binding member 70 is bent by approximately 20 ° with respect to the horizontal plane toward the above-described rotation center side (projection piece 72 side), and a bent portion 74 is formed.
The bent portion 74 is continuously formed from the near side edge of the binding member 70 to the far side edge. Furthermore, the front end side of the bent portion 74 is bent toward the substrate 22 side, and a pressing portion 76 for pressing the object to be bound X such as a document is formed.
The pressing part 76 is continuously formed from the near side edge of the bent part 74 to the far side edge. The pressing portion 76 has a grounding area that is grounded to the object to be bound X formed at its free end divided into a grounding portion 76a on the far side and a grounding portion 76b on the near side, and the grounding portion 76a on the far side is more. The grounding area is shorter than the grounding part 76b on the near side.
The pressing portion 76 is formed so as to incline toward the rotation center side of the binding member 70 from the bent portion 74 toward the substrate 22 when the binding member 70 is in a closed state where the binding member 70 lies on the substrate 22 side. Therefore, the bent portion 74 and the pressing portion 76 are connected in a substantially L shape. The pressing portion 76 presses the object to be bound X such as a document in a straight line. Here, when the binding member 70 is closed to the substrate 22 side, the bent portion 74 rises from the end side of the binding member 70 toward the inside of the binding member 70.

綴じ部材７０は、図８において示すように、突出片７２側より軸受板２４とは反対側の斜め上方に延びた立ち上がり部７０ａと、立ち上がり部７０ａの上端から斜め下方（水平面に対して略２２°）に向けて延びた平板状の架け渡し部７０ｂと、架け渡し部７０ｂの自由端に形成された折曲部７４および押圧部７６とを備え、前記立ち上がり部７０ａと架け渡し部７０ｂと折曲部７４および押圧部７６とは、一体形成されている。
架け渡し部７０ｂの自由端には、綴じ部材７０の手前側端縁より向こう側端縁に亘って斜め下方（垂直面に対して略１５°）に向けて折り曲げられて、屈曲部７０ｃが形成されている。屈曲部７０ｃの自由端には、折曲部７４が連設され、折曲部７４は、架け渡し部７０ｂと一定の間隔をおいて略平行に形成され、書類などの被綴じ物Ｘを押えるときに架け渡し部７０ｂ側に若干撓みつつ押圧部７６が書類などの被綴じ物Ｘを押圧し得るように形成されている。
綴じ部材７０の立ち上がり部７０ａは、操作レバー６０を固定用凸部２８から外すことができるスペースを確保するように、軸受板２４との間が上方に向かうに従って拡がる傾斜面（垂直面に対して略４５°傾斜した面）が形成されている。 As shown in FIG. 8, the binding member 70 includes a rising portion 70 a extending obliquely upward from the protruding piece 72 side on the side opposite to the bearing plate 24, and obliquely downward from the upper end of the rising portion 70 a (approximately 22 with respect to the horizontal plane). A flat plate-like bridging portion 70b extending toward (°), a bent portion 74 and a pressing portion 76 formed at the free end of the bridging portion 70b, and the rising portion 70a and the bridging portion 70b are folded. The curved portion 74 and the pressing portion 76 are integrally formed.
A bending portion 70c is formed at the free end of the bridging portion 70b by being bent obliquely downward (approximately 15 ° with respect to the vertical surface) from the front side edge of the binding member 70 to the far side edge. Has been. A bent portion 74 is continuously provided at the free end of the bent portion 70c, and the bent portion 74 is formed substantially parallel to the bridging portion 70b at a certain interval to press the object to be bound X such as a document. The pressing portion 76 is formed so as to be able to press the binding object X such as a document while being slightly bent toward the bridging portion 70b.
The rising portion 70a of the binding member 70 is an inclined surface (relative to a vertical surface) that expands toward the upper side so as to secure a space where the operation lever 60 can be removed from the fixing convex portion 28. A surface inclined by approximately 45 ° is formed.

ばね部材５０は、第１端部５０ｃが綴じ部材７０の内面に近似した形状に形成され、ばね部材５０の立ち上がり部５０ｄが綴じ部材７０の立ち上がり部７０ａの内面近傍にそしてばね部材５０の架け渡し部５０ｅが綴じ部材７０の架け渡し部７０ｂの内面近傍に位置するように、綴じ部材７０の内面側に設けられている。 The spring member 50 is formed in a shape in which the first end portion 50 c is similar to the inner surface of the binding member 70, the rising portion 50 d of the spring member 50 is in the vicinity of the inner surface of the rising portion 70 a of the binding member 70, and the spring member 50 is bridged The binding member 70 is provided on the inner surface side so that the portion 50 e is positioned in the vicinity of the inner surface of the bridging portion 70 b of the binding member 70.

折曲部７４には、矩形の貫通孔７８が形成され、ばね部材５０の第１端部５０ｃが架け渡し部７０ｂ側より嵌め込まれ、ばね部材５０の第１端部５０ｃの先端部（係止部５０ｆ）が折り曲げられて貫通孔７８から外れないようにされている。
この実施の形態においては、貫通孔７８は、綴じ部材７０の前後端に形成された突出片７２の間において、綴じ部材７０の折曲部７４の長手方向における中央よりも向こう側、すなわち軸４６に巻装された巻線部５０ａに近い位置に形成されている。
さらに、押圧部７６には、書類などの被綴じ物Ｘを押さえ付けたときの力による変形を防ぐために、直線状のリブ８０が長手方向に連続して形成され、架け渡し部７０ｂにも、書類などの被綴じ物Ｘを押さえ付けたときの力による変形を防ぐために、２条の直線状のリブが長手方向に連続して形成されている。 A rectangular through hole 78 is formed in the bent portion 74, and the first end portion 50 c of the spring member 50 is fitted from the bridging portion 70 b side, and the distal end portion of the first end portion 50 c of the spring member 50 (locking) The portion 50 f) is bent so as not to be detached from the through hole 78.
In this embodiment, the through-hole 78 is between the protruding pieces 72 formed at the front and rear ends of the binding member 70 and beyond the center in the longitudinal direction of the bent portion 74 of the binding member 70, that is, the shaft 46. It is formed at a position close to the winding part 50a wound around.
Furthermore, in order to prevent deformation due to the force when pressing the object to be bound X such as a document, a linear rib 80 is continuously formed in the longitudinal direction in the pressing portion 76, and the bridging portion 70 b In order to prevent deformation due to a force when the object to be bound X such as a document is pressed, two linear ribs are continuously formed in the longitudinal direction.

ばね部材５０の先端部（係止部５０ｆ）は、図９において示すように、綴じ部材７０が閉じた状態のときと開いた状態のときのいずれのときにも、基板２２の幅方向における位置は殆ど変わらない。そして、綴じ部材７０が綴じる書類などの被綴じ物Ｘを押圧して操作レバー６０を固定用凸部２８に係止させたときには、ばね部材５０の第１端部５０ｃが屈曲状態から伸びた状態になるとともに先端部（係止部５０ｆ）がねじれて係止部５０ｆが水平状態から下向きに変形するが、このばね部材５０の変形状態を許容できるように、貫通孔７８が折曲部７４の長手方向及び幅方向に延びている。 As shown in FIG. 9, the distal end portion (the locking portion 50 f) of the spring member 50 is positioned in the width direction of the substrate 22 in both the closed state and the open state. Is almost unchanged. When the object to be bound X such as a document to be bound by the binding member 70 is pressed and the operation lever 60 is locked to the fixing convex portion 28, the first end portion 50c of the spring member 50 is extended from the bent state. At the same time, the distal end portion (the locking portion 50f) is twisted and the locking portion 50f is deformed downward from the horizontal state, but the through hole 78 of the bent portion 74 is allowed to allow the deformation state of the spring member 50. It extends in the longitudinal direction and the width direction.

枢支部３０及び枢支部３４は、軸受板２４とは反対側の端縁が、綴じる書類などの被綴じ物Ｘの端縁を揃えるための軸受板２４の面と平行な面を有する、用箋揃え部９０を形成している。
枢支部３０及び枢支部３４は、軸受板２４とは反対側の端縁が、用箋揃え部９０の軸受板２４とは反対側の表面と同一平面（想像上）上に揃うように形成されている。
したがって、枢支部３０及び枢支部３４の端縁がガイドとなって、用箋揃え部９０に綴じる書類などの被綴じ物Ｘの端縁を当接させて綴じることができる。 The pivot support section 30 and the pivot support section 34 have an end edge opposite to the bearing plate 24 having a surface parallel to the surface of the bearing plate 24 for aligning the end edges of the objects to be bound X such as documents to be bound. A portion 90 is formed.
The pivot portion 30 and the pivot portion 34 are formed so that the end edge on the opposite side to the bearing plate 24 is aligned on the same plane (imaginary) as the surface of the note aligning portion 90 opposite to the bearing plate 24. Yes.
Therefore, the edge of the pivot part 30 and the pivot part 34 can be used as a guide, and the edge of the object to be bound X such as a document to be bound to the note aligning part 90 can be abutted and bound.

このように、構成された綴じ具２０は、操作レバー６０の手前側の自由端側を押し下げることにより、綴じ部材７０を、折曲部７４の長手方向における中央よりも向こう側をばね部材５０により押さえ付け、向こう側の突出片７２ａ及び手前側の突出片７２ｂを結ぶ線を回転中心として回動させ、基板２２との間に挟みこまれた被綴じ物Ｘを押さえ付けて綴じることができる。
そして、操作レバー６０の手前側の操作部６０ｃを押さえてロックするとき、綴じ部材７０の手前側の突出片７２ｂが低いので、ばね部材５０の係止部５０ｆが綴じ部材７０の折曲部７４を押さえる位置より遠い部位から被綴じ物Ｘを押さえ始めることにより、また、押圧部７６の自由端に形成された被綴じ物Ｘに接地する接地領域が、向こう側の接地部７６ａと手前側の接地部７６ｂとに分かれており、向こう側の接地部７６ａの方が手前側の接地部７６ｂより短い接地面積となるように形成されていることと相俟って、被綴じ物Ｘにかかる押える力のバランスは、手前側と向こう側と均等になる（図１４参照）。 In this manner, the binding tool 20 thus configured pushes down the free end on the near side of the operation lever 60, so that the binding member 70 is moved away from the center in the longitudinal direction of the bent portion 74 by the spring member 50. It is possible to press and bind the object to be bound X sandwiched between the substrate 22 by rotating the line connecting the protruding piece 72a on the far side and the protruding piece 72b on the near side as the rotation center.
When the operation portion 60c on the front side of the operation lever 60 is pressed and locked, the front projecting piece 72b of the binding member 70 is low, so that the locking portion 50f of the spring member 50 is the bent portion 74 of the binding member 70. When the object to be bound X is started to be pressed from a position far from the position where the object is pressed, the grounding area that contacts the object X formed at the free end of the pressing part 76 has a grounding part 76a on the far side and a grounding part on the near side. In combination with the grounding portion 76b, the grounding portion 76a on the far side is formed so as to have a shorter grounding area than the grounding portion 76b on the near side. The balance of force is equal between the near side and the far side (see FIG. 14).

綴じ部材７０の形態としては、図１５及び図１６に示すように、綴じ部材７０の架け渡し部７０ｂが断面円弧状のような形状としてもよい。 As a form of the binding member 70, as shown in FIG.15 and FIG.16, the bridging part 70b of the binding member 70 is good also as a shape like a cross-sectional arc shape.

このような綴じ具２０は、たとえば、図１７に示すように、基板２２に形成された貫通孔４４に取付用金具などを挿通することにより、ファイルなどに取り付けられる。そして、操作レバー６０を操作することにより、綴じ部材７０を開閉することができる。ここで、図１に示すように、操作レバー６０を上げることにより、ばね部材５０の第１端部５０ｃが綴じ部材７０を持ち上げ、基板２２と綴じ部材７０の押圧部７６との間に隙間が生じる。この隙間に書類などの被綴じ物Ｘが挿入され、操作レバー６０の手前側の自由端側を下げることにより、綴じ部材７０が閉じて、押圧部７６によって書類などの被綴じ物Ｘが基板２２に向かって押し付けられる。つまり、操作レバー６０を下げることにより、ばね部材５０の巻線部５０ａが締め付けられ、ばね部材５０の第１端部５０ｃによって、押圧部７６が基板２２方向に付勢される。 For example, as shown in FIG. 17, such a binding tool 20 is attached to a file or the like by inserting a mounting bracket or the like through a through hole 44 formed in the substrate 22. Then, by operating the operation lever 60, the binding member 70 can be opened and closed. Here, as shown in FIG. 1, by raising the operation lever 60, the first end 50 c of the spring member 50 lifts the binding member 70, and a gap is formed between the substrate 22 and the pressing portion 76 of the binding member 70. Arise. A binding object X such as a document is inserted into the gap, and the binding member 70 is closed by lowering the free end side of the front side of the operation lever 60, and the binding object X such as a document is transferred to the substrate 22 by the pressing portion 76. It is pushed toward. That is, by lowering the operation lever 60, the winding portion 50 a of the spring member 50 is tightened, and the pressing portion 76 is biased toward the substrate 22 by the first end portion 50 c of the spring member 50.

このとき、図１０及び１１に示すように、書類などの被綴じ物Ｘに対して、押圧部７６が斜めに押し付けられる。そして、書類などの被綴じ物Ｘを引き抜くような力が加わったとき、押圧部７６の傾斜方向とは逆向きの力が加わるとともに、折曲部７４および押圧部７６の屈曲部分をさらに屈曲させる向きの力が加わる。このような折曲部７４および押圧部７６の変形が元に戻ろうとする力により、押圧部７６から書類などの被綴じ物Ｘの引き抜きに対して抵抗力となるような力が加わり、書類などの被綴じ物Ｘが綴じ具２０から外れにくくなる。 At this time, as shown in FIGS. 10 and 11, the pressing portion 76 is obliquely pressed against the binding object X such as a document. When a force that pulls out the object to be bound X such as a document is applied, a force opposite to the inclination direction of the pressing portion 76 is applied, and the bent portion 74 and the bent portion of the pressing portion 76 are further bent. Directional force is added. Such a force that causes the deformation of the bent portion 74 and the pressing portion 76 to return to the original state adds a force that acts as a resistance force against the pull out of the binding object X such as a document from the pressing portion 76, such as a document. This makes it difficult for the object X to be detached from the binding tool 20.

さらに、押圧部７６が折曲部７４から基板２２側に向かうにしたがって綴じ部材７０の回転中心側に向かうように傾斜しているため、図１２及び１３に示すように、書類などの被綴じ物Ｘが厚くなっても、書類などの被綴じ物Ｘが薄いときと比してやや立ちぎみとはなるが、押圧部７６は書類などの被綴じ物Ｘの面に対して直交する位置にはなりにくく、書類などの被綴じ物Ｘの抜け落ちに対する抵抗力を保つことができる。 Furthermore, since the pressing portion 76 is inclined so as to be directed toward the rotation center side of the binding member 70 as it goes from the bent portion 74 toward the substrate 22 side, as shown in FIGS. Even if X becomes thicker, there is a slight rise compared to the case where the object to be bound X such as a document is thin, but the pressing portion 76 is at a position orthogonal to the surface of the object to be bound X such as a document. It is difficult to maintain the resistance against dropping of the object to be bound X such as a document.
