Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a binding tool, and more particularly, to a simple binding tool capable of binding a plurality of paper sheets having binding holes.
[0002]
[Prior art]
Conventionally, binders, files, and the like have been widely used when binding a plurality of documents having binding holes. A binding tool used for such a binder or the like includes a plurality of binding members that normally form a closed loop, and an operation unit that is provided so as to be operable to form and release the closed loop of these binding members. . The binding operation of the sheets in the binding tool is performed by operating the operation unit to release the closed loop of the binding member, inserting the binding member into the binding hole, and then forming the closed loop again.
[0003]
[Problems to be solved by the invention]
However, in such a binding tool, the binding member often has a structure in which a closed loop is maintained by a separate member such as a spring, or a structure in which a plurality of binding members operate simultaneously. It cannot be bound. In addition, there is a strong tendency to increase the number of parts of the binding tool as a whole, resulting in a complicated structure, which in turn increases the manufacturing cost.
[0004]
Incidentally, as a binding tool having a simple structure for binding a plurality of documents, a binding tool used for a ring notebook is known. This binding tool is composed of a single metal wire that is inserted into a plurality of binding holes and extends spirally. However, such a binding tool is not manufactured with the intention of being removed from the document, resulting in inconvenience that the bound document cannot be added or removed. Even if the binding tool is removed and the document is added or removed, the operation becomes extremely difficult and the operation time becomes long.
[0005]
OBJECT OF THE INVENTION
The present invention has been devised by paying attention to such inconveniences, and an object of the present invention is to make it easy to bind and release a document provided with a binding hole while having a simple structure. It is to provide a binding tool that can be performed.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a binding tool for binding paper sheets in which binding holes are formed,
It is provided so as to be insertable into the binding hole, and includes at least one binding member that forms a closed loop in an unloaded state,
The binding member is provided with a guide portion that can receive the end region of the paper sheet, and the guide portion is formed by providing a guide cutout portion along the axis of the closed loop.
A configuration is adopted in which the closed loop is forcibly released and the binding member is inserted into the binding hole by forcibly pushing the end of the paper sheet along the axis into the guide notch. ing. According to such a configuration, when binding paper sheets, the paper is inserted into the guide portion without performing the formation and release of a closed loop as in the conventional binding tool and the operation of inserting the binding member into the binding hole. The binding operation can be performed very easily and quickly by simply pushing the leaves. In addition, the end portion of the paper sheet can be easily received by the guide portion, and the closed loop can be smoothly released when binding is performed.
[0007]
Further, the present invention is a binding tool for binding paper sheets in which a plurality of binding holes are formed,
A strip-shaped base along the direction in which the binding holes are arranged, and a plurality of binding members formed at predetermined intervals along the direction in which the pieces of the base extend, and forming a closed loop in an unloaded state;

[0008]
DETAILED DESCRIPTION OF THE INVENTION
The binding member according to the present invention may be formed in a split mold having regions where the leading ends overlap each other, and the guide portion may be provided on the leading end. According to this, after the paper sheet having passed through the guide portion is forcibly released from the overlapping state by the pushing, the binding member is inserted into the binding hole to form a closed loop again, which is shown in the conventional example. The closed loop can be formed and released with an extremely simple structure without providing an operation unit or the like. Further, even when the diameter of the closed loop is expanded unintentionally, it is possible to reliably prevent the sheets from falling off.
[0009]
Further, the binding member is also formed in a split type in which at least a part of the front end edge substantially abuts, and the guide portion is provided on the front end side. Even with such a configuration, by pushing in the paper sheets, the abutting state of each leading edge is released, and the binding member is inserted into the binding hole, thereby easily and quickly forming the closed loop and releasing it. It can be carried out.
[0011]
In addition, the binding member may be formed of a plate material or a wire material that can be elastically deformed by the pushing, thereby forming and releasing a closed loop of the binding member without using another member such as a spring, The cost of the binding tool can be reduced by making it possible to obtain a single molded product.
[0012]
Moreover, each center of each said guide part can take the structure that it is set to the position used as a zigzag with respect to the virtual centerline along the extending direction of a base. According to such a configuration, when the paper sheets are pushed in and the closed loop of each binding member is forcibly released, the reaction force applied to the paper sheets can be reduced, and the binding operation is performed smoothly. It becomes possible. In addition, it is possible not only to effectively avoid the possibility of the binding hole being caught by the guide portion during the page turning operation of the paper sheet, but also when the diameter of the closed loop is expanded carelessly. Can be reliably prevented.
