Description

  The present invention relates to an opener, and more particularly to an opener used to open a binding used for a ring binder or a ring file, for example.

  A binding tool having a plurality of binding rings is used for the ring binder and the ring file. The binding tool is attached to the inside of the cover, and a binding object such as paper is bound. The binding ring of the binding tool has two binding members that can be opened and closed, and these binding members are biased in the opening direction. A binding ring locking portion is formed on the front end side of the binding member, and the two binding members can be kept closed by being locked by the binding ring locking portion.

  In such a binding tool, there are several methods for opening and closing the binding members, but by displacing the two binding members in opposite directions along the center line between the two binding members constituting the binding ring. There is a binding tool of a type that releases the binding ring locking portion. In such a binding tool, the two binding members that are closed are sandwiched between the thumb and the index finger, and the two binding members are twisted so that they are displaced in the opposite directions, thereby releasing the binding ring locking portion. Then, the binding member can be opened. Therefore, the binding object can be bound into the binding tool by twisting the binding ring to open the binding member, inserting the binding member into the hole formed in the binding object, and closing the binding member ( Patent Document 1).

  However, as illustrated in FIG. 28, when a large number of objects to be bound 2 are bound into the binding tool 1, the range of the binding member 3 exposed from the objects to be bound 2 is reduced. Therefore, it becomes difficult to twist the binding member 3 and the binding member 3 is difficult to open.

  Therefore, a main object of the present invention is to provide an opener that can easily open a binding member of a binding tool even if a large number of objects to be bound are bound.

The present invention includes a binding ring formed by closing a pair of openable and closable binding members, and a holding member having a length capable of providing the binding rings at intervals. An opener for opening the binding member by attaching the pair of binding members to the opening tool by mutating the pair of binding members in a direction opposite to each other along a direction in which the binding ring is displaced. The base member having a longitudinal direction and an interval corresponding to the interval between the pair of binding members are provided in the base body so that the binding member penetrates at a position spaced from one end side in the longitudinal direction of the base member. And the binding is formed such that one end of the one through hole and one end of the other through hole are disposed at positions shifted from each other in the longitudinal direction of the base body. When the base is slid to one side along the displacement direction, the binding member is displaced by pressing one of the binding members against one end of the through hole, and the binding member It is an opener comprised so that the other might not be pushed by the other edge part of the said through-hole.
By sliding the base of the opener to one side along the direction in which the binding ring is displaced, only one of the binding members constituting the binding ring is displaced, and the binding member can be opened. Since the through hole is formed at a position spaced from one end side in the longitudinal direction of the base body, the binding member can be opened by pressing the one end side in the longitudinal direction of the base body and sliding the base body. The opener can push the binding member on the holding member side instead of the front end side of the binding member, so that the binding object can be bound on the opener, and the binding member can be moved regardless of the amount of the binding object. Can be opened.

In such an opener, the opener further includes another through-hole through which a binding ring composed of another binding member that operates in conjunction with the binding member that penetrates the through-hole, and the other through-hole includes a wide portion and a width. A narrow portion, and when the substrate is slid to one side along the center line of the holding member, another binding member is positioned at the wide portion of the other through hole, and along the direction in which the binding ring is displaced. When the base is slid to the other side, the narrow portion of the other through-hole can be brought closer to the other binding member.
Open the binding member by sliding the opener base to one side along the direction in which the binding ring is displaced, and then slide the base to the other side, so that another binding member interlocked with the binding member is another through-hole. It comes to be located in the wide part. Then, by sliding the base body to the other side, the narrow portion of the other through-hole approaches another binding member, and the other binding member is displaced in the closing direction. Thereby, the binding member can be opened and closed depending on the sliding direction of the opener.

Further, the base is formed with a hinge portion that is bent along the longitudinal direction of the base in the center between the through holes formed at intervals corresponding to the distance between the pair of binding members. Is preferred.
By forming the hinge portion on the base of the opener, the strength of the base can be increased and the deformation of the base can be prevented. Further, by forming the hinge portion on the base, the binding member can be pushed at a position close to the holding member of the binding tool through the through-hole formed in the base.

  According to this invention, the binding member can be pushed on the holding member side of the binding tool by attaching the opener to the binding tool. Therefore, the binding object can be bound into the binding tool on the opener, and the binding member of the binding tool can be opened by operating the opener even when a large number of binding objects are bound. Since the opener has a base having a longitudinal direction, the opener can be operated at the end of the cover, for example, by arranging the base so as to reach the lower end of the cover from the binding member of the binding tool.
