Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a base of a binding device, and more particularly, an operation of fixing a base of a binding device to a spine or a back cover as a surface to be fixed can be performed very easily. Also, the present invention relates to a base fixing structure capable of promoting separation and disposal of both components or reuse of components.

[0002]

2. Description of the Related Art Conventionally, binders having a binding device on the inner surface side of a spine or a back cover are commercially available. The binding tool used for the binders includes a base, a pair of binding plates disposed on both left and right sides of the base, and a binding rod extending between the binding plates.

When the base is fixed to the spine, a plurality of holes are formed at the coaxial line position between the base and the spine, and the base is fixed with rivets through the holes. Has been adopted.

[0004]

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 a proper fixing position is required. Is disadvantageously reduced. In the binders, the cover side is a combustible material, 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 them, and in fact, they are discarded without being separated.

[0005] Separate disposal has recently been strongly demanded from the viewpoint of recent waste disposal problems or the protection of the natural environment. More preferred. In this regard, for example, a binding device used as a binder is almost never unusable, and only the front cover is generally obsolete and unusable.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to not only make it easier to separate and discard, but also to make it easier to reuse parts that still have a value that can be used as parts, and thus to dispose of them. An object of the present invention is to provide a base fixing structure for a binding tool that can contribute to the regulation of the total amount of articles.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a binding device having a base fixed to a surface to be fixed such as a spine, and a binding member provided on the base. In the base fixing structure, a configuration is adopted in which the base is detachably provided on the fixed surface using a base fixing tool configured in combination.

According to such a configuration, the necessity of providing a fixing member such as a rivet can be eliminated, and the binding device can be fixed to the surface to be fixed by the base fixing device. By separating, the binding tool can be removed from the surface to be fixed. Therefore, in the case of discarding, not only is it easy to separate the cover side such as the binder forming the fixed surface from the binding device, but also only replace the cover side with a new one, and the binding device is not replaced. Reuse can be achieved, thereby making 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 device 10 according to the present embodiment to the spine 11 and an overall assembling method will be described with reference to FIGS.

First, when fixing the base 13 on the spine 11, the positioning projection 33 projecting downward from the fixing surface 26 of the base 13 is inserted into the hole 11A of the spine 11.
Within.

Next, the hook member 43 and the rotating member 4
What is necessary is just to fix the base 13 using the base fixture 14 which combines 4 with. 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 front side of the spine 11, that is, on the outer side. Then, the outer portion 45A is moved in the direction indicated by the arrow a in FIG. 9 and attached so that the outer surface portion of the spine 11 is positioned on the inner surface side of the outer portion 45A. Is rotated in the direction indicated by the arrow b, and is rotated to a position where the upper cover surface portion 52 is in a substantially horizontal posture as indicated by the two-dot chain line. This rotation is performed using a 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 when the rotating member 44 is in a substantially horizontal posture, the lower end of the rear end wall 54 and the outside Pinching force is generated between the base 13 and the back cover 11A.
It will be fixed to. In this fixed state, a constant holding force is maintained unless an external force for rotating 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 45C formed at the inner end, the rotating member 44
It is maintained so as not to move from the holding position with the hook member 43, that is, the horizontal posture.

Around the time when the base 13 is fixed, the base 13 supports the shaft pin 17. Then, while the operation member 15 is disposed in each of the storage portions 37 of the base 13, the operation member 15 is set so that the throttle portion 17 </ b> A of the shaft pin 17 fits in the holding portion 59.

Next, as shown in FIG. 13, when the pair of binding plates 20 and 21 are combined and lowered to the base 13 side from above, the shaft pin 17 is formed by the curved surface of the lower end outer peripheral surface of the lower projecting piece 83. Comes to displace the axis position inward, the shaft pin 17 enters through the gap C between the lower projecting piece 83 and the upper projecting piece 82, and the shaft pin 17 returns to the initial axis position by further descending. It will ride on the lower protruding piece 83, whereby each binding plate 2
The mounting of 0, 21 on the base 13 is completed.

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

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

The detailed structure of the binding device 10 according to the present invention, for example, the external shape and the like of the base 13 and the binding plates 20 and 21 are not limited to those of the above-described embodiment. It can be changed as appropriate. For example, the base 13 has a shape in which the fixed surface portion 26 and the intermediate portion 27 have different plane heights, but may have a shape located on the same plane.

[0032]

As described above, according to the present invention,
The necessity of providing a fixing member such as a rivet can be wiped out, and the binding device can be fixed to the surface to be fixed by the base fixing device composed of the combination, while the binding device is released and separated to separate the binding device to the surface to be fixed. It is possible to remove from. Therefore, in the case of discarding, not only is it easy to separate the cover side such as the binder forming the fixed surface from the binding device, but also only replace the cover side with a new one, and the binding device is not replaced. Reuse can be achieved, thereby making it possible to achieve effective use of resources while contributing to the regulation of the total amount of waste.
