Description

この発明は、綴具に関するものであり、特に、例えばセルリング式ノート又は綴じ穴のあるリーフを綴じる手帳類に用いられる綴具である。   The present invention relates to a binding tool, and in particular, a binding tool used for notebooks that bind a cellling notebook or a leaf having a binding hole, for example.

従来、リング状の部材を用いて、穴の開いたリーフを綴じていたノートは、そのリングの形状に沿って、３６０°リーフを広げること、すなわち開くだけでなく、リーフを折り返しノートの表面側と裏面側とを重ねることができ、１８０度しか開かないノートと比して半分のスペースで活用することができた。しかし、このセルリング式ノートは、リーフの差し替えができない欠点があった。
一方、特許第２５２８２８９号及び実開平７−１７５７８号の綴具を用いた手帳、すなわちリーフを綴じる綴杆部が開閉可能な手帳は、リーフの差し替えが可能である。 Conventionally, a notebook in which a leaf with a hole is bound using a ring-shaped member is not only widened by 360 ° leaf along the shape of the ring; Can be used in half the space compared to a notebook that opens only 180 degrees. However, this cellling type notebook has a drawback that the leaf cannot be replaced.
On the other hand, a notebook using a binding tool disclosed in Japanese Patent No. 2528289 and Japanese Utility Model Laid-Open No. 7-17578, that is, a notebook that can open and close a binding portion that binds a leaf can be replaced with a leaf.

特許第２５２８２８９号Japanese Patent No. 2528289 実開平７−１７５７８号ACT 7-17578

しかしながら、特許第２５２８２８９号の綴具は、所要枚数の紙葉を綴って形成された紙葉綴の複数部がコ字形状の表紙内部に収容されてなる手帳であって、この表紙の背表紙部分が伸縮性素材で形成され、この背表紙部分の内側表面に沿って複数のゴム紐がその一端を背表紙の上端近傍に他端を背表紙の下端近傍に固定されて平行に張架され、このゴム紐と背表紙部分との間で前記紙葉綴の綴合わせ部分が挾持されてなる多用途手帳であるために、リーフの差し換えに比較的手間がかかり、１８０度しか開かない。
また、実開平７−１７５７８号の綴具は、複数の綴環を起立した第１部材と第２部材とを共通の軸線で枢着している。したがって、第１部材と第２部材とは分離しないが、綴環１５，１７の基部に複数の綴環を連結する棒状の連結部を形成し、その連結部の内側面から張出部２３を突設しているために、例えば、机の上に置いて綴具を開こうとしても、綴環の基部の外側が机の面に突き出たり、綴環が充分開かず、リーフの出し入れが比較的困難である。
それゆえに、この発明の主たる目的は、リーフの差し換えをし易いように綴杆を開き易く且つ閉じ易い綴具を提供することである。 However, the binding tool disclosed in Japanese Patent No. 2528289 is a notebook in which a plurality of paper sheet bindings formed by binding a required number of paper sheets are housed inside a U-shaped cover, and the back cover of this cover A portion is formed of a stretchable material, and a plurality of rubber straps are stretched in parallel along the inner surface of the spine portion, with one end fixed near the upper end of the spine and the other end near the lower end of the spine. Since this is a multipurpose notebook in which the binding portion of the paper sheet binding is held between the rubber strap and the spine portion, it takes a relatively long time to replace the leaf and opens only 180 degrees.
Further, in the binding tool disclosed in Japanese Utility Model Laid-Open No. 7-17578, a first member and a second member that stand up with a plurality of binding rings are pivotally attached to a common axis. Therefore, the first member and the second member are not separated, but a bar-like connecting portion that connects a plurality of binding rings is formed at the base of the binding rings 15 and 17, and the protruding portion 23 is formed from the inner side surface of the connecting portion. For example, even if you try to open the binding tool by placing it on a desk, the outside of the base of the ring will protrude to the surface of the desk, the ring will not open sufficiently, and the insertion and removal of the leaf will be compared. Difficult.
Therefore, a main object of the present invention is to provide a binding device that can easily open and close a binding rod so that a leaf can be easily replaced.
