Description

  The present invention relates to a binder, and more specifically, the operation of fixing the base of a binding tool to a back cover or back cover serving as a fixed surface can be performed very easily, and both are disposed of separately or reuse parts. The present invention relates to a binder having a base fixing structure that can promote the above.

  Conventionally, binders comprising a binding tool on the inner surface side of a back cover or back cover are commercially available. The binding tool used for the binders includes a base, a pair of binding plates disposed on the left and right sides of the base, and a binding rod extending between the binding plates.

  When fixing the base to the spine, a configuration is generally adopted in which a plurality of holes are formed at the coaxial line position between the base and the spine and fixed with rivets through the holes. Yes.

  However, in the fixing method using the rivet, a manufacturing facility such as a dedicated rivet driving device is indispensable, and an operation for maintaining the fixing position in an appropriate state is required, and the manufacturing efficiency is lowered. For binders, the cover side is combustible, while the binding side is usually made of metal or resin to maintain load bearing performance. It is required to separate these. However, in the rivet fixing method, it is difficult to separate the two, and the fact is that they are discarded without being separated.

  By the way, although the separation disposal has been strongly demanded recently from the viewpoint of protecting the recent dust disposal problem or the natural environment, it is more preferable to fundamentally prevent the generation of dust. In this respect, for example, the binding tool used for the binder is hardly unusable by itself, and it is general that only the cover side becomes obsolete and cannot be used.

  Here, the object of the present invention is to make it easier to separate and discard the waste, and to facilitate the reuse of the part that is still worth using as a part. It is in providing the binder which can also contribute.

In order to achieve the above object, the present invention is a binder having a binding tool including a base fixed to a fixed surface such as a spine and a binding member provided on the base,
A hole is formed in each of the fixed surface and the base, and a base fixing tool is provided for removably fixing the base to the fixed surface via a portion extending into the hole.
The fixed surface is a spine provided with a film for loading a heading label on the outer surface side ,
The base fixture includes a first fixture having an outer portion located on the outer surface side of the spine and a second fixture combined therewith,
The base has a shape in which the plane heights of the fixed surface portion and the intermediate portion are located on the same plane,
Attach the base fixture from the inner side of the spine,
The base is fixed to the back cover by the base fixing tool at a position where the second fixing tool is in a substantially horizontal position along the base with the outer portion attached to the outer surface of the spine. It is.

In the present invention, the binding tool includes a pair of left and right binding plates, and a binding rod that is fixed at two positions on the relative surfaces of the binding plates and that fits in the axial direction in a telescopic relationship with each other. Adopted.
Further, the base has a configuration in which a positioning projection piece is formed in a hole formed in the spine.

  According to the present invention, the necessity of providing a fixing member such as a rivet can be eliminated, and the binding tool can be fixed to the fixed surface with the base fixing tool constituted by the combination, while the binding tool can be detached from the fixed surface. It becomes. Therefore, when discarding, not only the cover side such as the binder forming the fixed surface and the binding tool can be easily separated, but also only the cover side is replaced with a new one. Reuse can be achieved, and this makes it possible to achieve effective use of resources while contributing to the regulation of the total amount of waste.

  Next, a method for fixing the binding tool 10 according to this embodiment to the spine 11 and an entire assembly method will be described with reference to FIGS. 9 and 14.

  First, when the base 13 is fixed on the spine cover 11, the positioning protrusion 33 protruding downward from the fixing surface portion 26 of the base 13 is positioned in the hole 11 </ b> A of the spine cover 11.

  Next, the base 13 may be fixed using the base fixture 14 configured by combining the hook member 43 and the rotating member 44. That is, as shown in FIG. 9, the outer portion 45A of the hook member 43 is set so as to be exposed on the surface side of the spine cover 11, that is, on the outer surface side. Then, the outer portion 45A is moved in the direction indicated by the arrow a in FIG. 9 so that the outer surface portion of the spine cover 11 is positioned on the inner surface side of the outer portion 45A. Is rotated in the direction indicated by the arrow b to rotate the upper cover surface portion 52 to a position where the upper cover surface portion 52 is in a substantially horizontal position as indicated by a two-dot chain line. This rotation is performed with the contact point between the lower end of the rear end wall 54 of the rotating member 44 and the upper surface of the base 13 as a fulcrum, and the lower end of the rear end wall 54 and the outer side when the rotating member 44 assumes a substantially horizontal posture. A clamping force is generated between the portion 45A and the base 13 is fixed to the spine 11 by this. In this fixed state, a constant clamping force is maintained unless an external force that rotates the free end side of the rotating member 44 in the opposite direction is applied, and the upper portion of the vertical portion 45B is maintained. Due to the presence of the protrusion 45 </ b> C formed at the inner end, the rotating member 44 is kept from moving from the holding position with the hook member 43, that is, from the horizontal posture.

  The shaft pin 17 is supported by the base 13 before and after the fixing of the base 13. Then, the operating member 15 is arranged in each accommodating portion 37 of the base 13, and is set so that the throttle portion 17 </ b> A of the shaft pin 17 is accommodated in the holding portion 59.

  Next, as shown in FIG. 13, when the pair of binding plates 20, 21 are combined and lowered to the base 13 side from above, the shaft pin 17 is brought inward by the curved surface of the lower end outer peripheral surface of the lower protruding piece 83. The axial position is displaced, the shaft pin 17 enters through the gap C between the lower protruding piece 83 and the upper protruding piece 82, and the shaft pin 17 returns to the initial axial position by further lowering, and the lower protruding piece 83, and the mounting of the binding plates 20 and 21 to the base 13 is completed.

  Here, when binding a document (not shown), any one of the operation members 15 may be pushed in. By this pushing, the shaft pin 17 is displaced in the axial position as described above, so that the mutual engagement between the shaft pin 17 and the lower projecting piece 83 is released, whereby the binding plate 20 or 21 is removed from the base 13. By separating and moving the binding plates 20 and 21 in directions away from each other, the mutual engagement of the binding rods 23 and 24 fitted in the axial direction is released. Note that the two operating members 15 may be simultaneously pressed to remove the binding plates 20 and 21 from the base 13 at the same time.

  Therefore, according to such an embodiment, the base 13 can be easily attached to and detached from the spine cover 11. Further, since the hook member 43 can be set so as to be hooked from the inner surface side of the spine cover 11, for example, even when a film for loading a heading label is provided on the outer surface side of the spine cover The base fixture 14 can be mounted without any trouble.

  It should be noted that the detailed structure of the binding tool 10 according to the present invention, for example, the external shape of the base 13 and the binding plates 20 and 21 is not limited to the above-described embodiment, and may be changed as appropriate as long as the same function is achieved. be able to. For example, the base 13 is provided in a shape in which the plane heights of the fixed surface portion 26 and the intermediate portion 27 are different from each other, but can be formed in a shape located on the same plane.
