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, it is very easy to fix a base of a binding device to a spine or back cover serving as a surface to be fixed. The present invention relates to a base fixing structure capable of separating a binding device and a cover and promoting separation and disposal or reuse of the binding device.

[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 tools used for the binders include, for example,
It comprises a base, a pair of binding plates disposed on both left and right sides of the base, and a binding rod extending between these 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 case of binders, the cover side is flammable, while the binding side is usually made of metal to maintain load-bearing performance. Is required. 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 itself, and only the front cover is generally obsolete and unusable.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention not only to make it easier to separate and discard, but also to make it easier to reuse parts that are still valuable as parts, that is, binding devices. Another object of the present invention is to provide a binding device base fixing structure that can contribute to the total amount of waste.

[0007]

In order to achieve the above object, a binding device having a base and a binding member provided on the base is removably fixed to a surface to be fixed via a predetermined base fixing device. In the base fixing structure, the base fixing tool includes a penetrating member that penetrates the fixed surface, and a wedge member that engages with the penetrating member and regulates the falling off of the penetrating member. When the wedge member or the penetrating member is engaged with a predetermined position of the penetrating member, a base is sandwiched between the fixed surface and the wedge member or the penetrating member.

According to such a configuration, the base can be attached to and detached from the surface to be fixed by attaching and detaching the wedge member to and from the penetrating member. Therefore, compared to the conventional fixing method using rivets, the base can be attached very easily. Separation of the base and the surface to be fixed becomes possible, and separate disposal or reuse of the binding device can be promoted.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention also relates to a base fixing structure for detachably fixing a base and a binding device provided with a binding member provided on the base to a surface to be fixed via a predetermined base fixing device. The base fixing tool includes a penetrating member that penetrates the fixed surface and the base, and a wedge member that engages with the penetrating member and regulates the falling off of the penetrating member. A configuration is also adopted in which a base is sandwiched between the wedge member or the penetrating member and the surface to be fixed when the base is engaged with a predetermined position of the penetrating member. With this configuration, the penetrating member penetrates through the base, so that the base can be easily positioned and the fixed state of the base can be further stabilized.

Further, the present invention provides a base fixing structure for removably fixing a binding device having a base and a binding member provided on the base to a surface to be fixed via a predetermined base fixing device, The base fixture has a plate-shaped outer member positioned on the outer surface of the fixed surface, and a penetrating member that is provided continuously from the surface of the outer member and extends through the fixed surface and the base. A wedge member engageable with the penetrating member, and a fixed surface and a base between the wedge member or the penetrating member and the outer member when the wedge member is engaged with a predetermined position of the penetrating member. Is pinched,
With this configuration, the above-mentioned object is satisfactorily achieved.

In the base fixing structure, an inclined surface facing the penetrating member and the wedge member is formed, and the pinch force is gradually increased by inserting the wedge member in one direction that changes the relative position of the inclined surface. In addition to the configuration, a hole that is opened in a direction substantially perpendicular to the extending direction of the penetrating member is provided, and the wedge member is inserted into the hole to clamp the fixed surface. And a wedge member is inserted into a gap between these upright pieces to fix the surface to be fixed with a part of the upright pieces.
By arbitrarily selecting these configurations, the engagement relationship between the penetrating member and the wedge member can be arbitrarily selected, and the degree of freedom in design according to the type or shape of the binding tool can be provided.

The wedge member is connected to the outer member so as to be bendable at a position adjacent to the penetrating member, and is provided so as to be engageable with the penetrating member by bending the wedge member. A configuration can also be employed.
Accordingly, the wedge member is provided integrally with the outer member, so that the wedge member is less likely to be lost in the state where the engagement is released.
