Description

  The present invention relates to a binder technology including a fastening member that removably fixes a substrate portion of a binding tool for binding documents or the like to the inner surface side of a spine cover.

  In the binders, a binding tool is fixed to the inner surface side of the back cover of the cover body. Conventionally, various types of binding tools are known. In particular, in a thick binder capable of binding a large number of documents, for example, a substrate portion, a pair of binding plates arranged on the left and right sides of the substrate portion, and a binding rod passed between the binding plates The binding tool provided with is widely adopted.

  When fixing the board part of the binding tool to the inner surface side of the spine, a method is generally adopted in which a plurality of holes that match each other are formed in the spine and the board, and the holes are used to fix with rivets. Yes.

  In this fixing method using rivets, once the binding tool is fixed to the cover body, it is difficult to separate them. In general, the cover body is a combustible material made of cardboard or a synthetic resin sheet, and the binding tool is a non-combustible material mainly composed of metal. For this reason, there has been a problem that it is difficult to deal with the waste disposal problem in recent years and the separate disposal required from the viewpoint of protecting the natural environment. In addition, there is a problem that it is impossible to reuse a binding tool made of metal and having durability.

A technique in consideration of these points is described in Patent Document 1. The binder described in Patent Document 1 includes a binding tool that is detachably fixed to an inner surface side of a spine cover via a base fixing tool (fastening member). The base fixture is entirely made of resin, and is provided at a penetrating member that penetrates the spine and the base, an insertion shaft portion that can be inserted into and removed from a hole formed in the penetration member, and a position adjacent to the insertion shaft portion. Hook portion. When the insertion shaft portion is inserted into the hole of the penetrating member, the base is fixed to the spine.

However, the binder provided with such a detachable binding tool has problems to be solved in the following points.
(1) Since the hook part protruded from the main body of the wedge member, which is a constituent member of the base fixture, is provided at a position adjacent to the insertion shaft part, and the hook part is close to the wedge member main body, the resistance of the hook part In order to remove and attach the wedge member from the penetrating member by bending the hook portion, a large force is required, and the removal is particularly difficult.

(2) Since the outer sides of the two insertion shaft portions are in an open state, the insertion shaft portion easily comes into contact with the outside during assembly in the production process and removal from the penetrating member, resulting in deformation and breakage. Cheap. The same can be said about deformation and breakage even if the hook portion is provided outside. In addition, in the structure in which the hook portion is provided adjacent to the insertion shaft portion and the insertion shaft portion, if the shaft diameter is reduced and the base fixture is made compact, it is necessary to increase the number of shafts in order to maintain the strength. If the shaft diameter is reduced, there is a disadvantage that deformation and breakage are more likely to occur.

Therefore, the problem of the present invention is to reduce the thickness of the fastening member corresponding to the conventional base fixture,
It is an object of the present invention to provide a binder and a fastening member used for the binder which can be made compact as a whole, can exhibit a robust and excellent function, and can be easily attached and detached.

In order to solve the above-mentioned problems, the present invention employs the following means.
The present invention is a fastening member for detachably fixing a substrate portion of a binding tool to an inner surface side of a spine cover, and includes a base member and a plate-like slide member attached to the base member. Has a protrusion that penetrates the substrate of the spine and the binding tool and protrudes on the substrate, and a plurality of engaging portions provided on both sides of the protrusion, and the slide member is connected to the base member. It has a plurality of engaging pieces that respectively engage with the engaging portions when mounted.

  According to the present invention, the engaging members are provided on both sides of the protruding portion that protrudes on the substrate through the spine and the substrate, and the plurality of engaging pieces that respectively engage with the engaging portions are provided on the slide member. Therefore, the whole fastening member can be made thin. In particular, since there are two engaging portions for one protrusion and at least two corresponding engaging pieces, even if each engaging piece is thinned, the entire engaging piece It becomes possible to maintain the required strength. Moreover, since the engagement piece has an L-shaped cross section, it is more resistant to deformation and breakage than the shaft structure. Thereby, thickness reduction of a fastening member can be achieved.

  In the present invention, the engaging portion is formed in a substantially T-shaped cross section, and a protrusion extending in the inserting direction of the engaging piece is formed on the surface of the engaging piece. It is desirable that a guide groove that allows entry of the strip is formed. When the engaging strip is provided with a protrusion along its length, both the function of reinforcing the engaging strip itself and the guide function can be exhibited. Furthermore, when the protrusion of the engagement piece is engaged with the engagement portion, when an excessive load is applied by the document, the engagement piece of the slide member is deformed outward, and the binding tool is about to fall off. Can be prevented.

  Further, if the width of the spine is narrow (for example, less than 5 cm), the number of the protrusions may be one. In this case, the slide member has two engagement pieces corresponding to the engagement parts of the protrusions. Provided. If the width of the spine becomes wider (for example, 5 cm or more), a pair is provided at intervals in the width direction of the spine, and the slide member has four engagements corresponding to the engaging portions of the protrusions. It is desirable that a piece is provided. Thus, when it is set as the structure provided with four engagement pieces, even if each engagement piece is formed in thin plate shape, it can be set as the design which has sufficient intensity | strength as a whole.

Locking means configured to include a convex portion provided on one of the opposing surfaces of the slide member and the substrate, and a concave portion provided on the other and fitted with the convex portion between the slide member and the substrate. Can be provided. In this way, when the concave-convex fitting is adopted, it is possible to make the locking means simpler than the provision of the hook member, and it is difficult for deformation and breakage to occur.

  The slide member may be provided with a support piece that can be elastically deformed, and the support piece may be provided with a convex portion. Thus, when a convex part is provided in the support piece which can be elastically deformed, the amount of protrusions and depressions of a convex part can be changed by the elastic deformation action of a support piece. Thereby, the function as a latching means can be improved, improving the operativity at the time of attaching or detaching a slide member to a base member.

The present invention is a binder including a fastening member for detachably fixing a substrate portion of a binding tool to an inner surface side of a spine cover, and the fastening member includes a base member and a plate-like member attached to the base member. The base member includes a retaining portion disposed on the outer surface side of the spine cover, a projecting portion that projects through the substrate of the spine cover and the binding tool, and both sides of the projecting portion. The slide member has a plurality of engagement pieces that respectively engage with the respective engagement portions when mounted on the base member.

  According to the fastening member of the present invention, the thickness can be made thinner than that of the conventional base fixture, so that the overall compactness can be achieved. In addition, since the hook member is not provided, the configuration is simple and the workability is improved. It is excellent in that the deformation after molding is small.

  Here, if the width of the spine is narrow (for example, less than 5 cm), the number of the protrusions may be one. In this case, the slide member includes two engagement pieces corresponding to the engagement portions of the protrusions. Is provided. If the width of the spine becomes wider (for example, 5 cm or more), a pair is provided at intervals in the width direction of the spine, and the slide member has four engagement pieces corresponding to the engagement portions of the protrusions. It is desirable to be provided.

  Further, it is desirable that the slide member is provided with a convex portion that fits into a concave portion provided on the binding member substrate when the slide member is attached to the base member and positions the slide member at the attachment position. Thus, when a convex part is provided in a slide member, the shaping | molding which makes a convex part the required protrusion amount becomes easy, and also a recessed part can be formed with a simple punching process with respect to the board | substrate of a binding tool. . As a result, the locking means can be simplified, the amount of material used is small, and the thickness can be reduced.

  The slide member may be provided with a support piece that can be elastically deformed, and the support piece may be provided with a convex portion. Thus, when a convex part is provided in the support piece which can be elastically deformed, the amount of protrusions and depressions of a convex part can be changed by the elastic deformation action of a support piece. Thereby, the function as a latching means can be improved, improving the operativity at the time of attaching or detaching a slide member to a base member.

  According to the present invention, it is possible to obtain a binder that can reduce the thickness of the fastening member, reduce the overall size of the fastening member, exhibit a robust and excellent function, and can be easily attached and detached, and a fastening member used therefor.
