Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a binding tool that is attached to the inside of a file cover and is used to properly bind and unload papers.

[Conventional technology]

It is well known that many so-called file binding devices of the above-mentioned type have been proposed and put into practice, without citing any particular publications or gazettes.
This generally consists of an L-shaped fixing plate equipped with a binding tube and an L-shaped lid plate equipped with a binding rod, and when used, the binding rod is inserted into the binding tube, and the lid plate is attached to the fixing plate as appropriate. It is arranged to be anchored using tightening means or locking means.

[Problem that the invention seeks to solve]

In a binding device having such a structure, when taking out the bound papers, the lid plate must be removed from the fixing plate by releasing or releasing the tightening means or the locking means and then manually taking out the lid plate. However, if a configuration can be proposed in which the lid plate is automatically taken out when the tightening means or locking means are released, it is expected that the file operation will be even more convenient and the product value will be significantly increased.

Therefore, a general object of the present invention is to provide a file binding device which can be easily removed by easily popping out the cover plate of the binding device when the locking means is released. be.

[Means for solving problems]

In order to achieve the above object, in the file binding device according to the present invention, an L having at least two binding tubes in the flat part and having a vertical wall at the longitudinal end.
It consists of a shape fixing plate, and an L-shaped cover plate that has a binding pin on its flat part facing the binding tube and has a vertical wall at its longitudinal end, and the vertical wall is formed as a double structure having a slit. , an elastic wire is installed in the slit with its both ends held, a locking lug is provided in the center of the vertical wall, and a locking lug is provided at the longitudinal edge of the vertical wall, and the slit is slightly thinner than the vertical wall. a fitting portion to be fitted into the interior thereof is extended, at least one pressing tongue for pressing the elastic wire is protruded from an edge of the fitting portion, and the locking portion is further provided at the top of the vertical wall. A shoulder is provided to engage the ear.

Support arms, the tops of which are located slightly above the holding points, are symmetrically provided near the inner sides of the holding points at both ends of the elastic wire to hold the elastic wire in a substantially arcuate shape.

In addition, pressing tongues are provided at both ends of the fitting part, and supporting arms of the elastic wire are symmetrically provided near the inner side of the holding points at both ends of the elastic wire, the tops of which are located below the holding points. It is also possible to hold the elastic wire 24 in a wavy shape so that the pressing tongues abut against both ends of the elastic wire 24.

Furthermore, a pocket can be formed in the center of the vertical wall, and the locking ear can be elastically installed in this pocket.

In addition, in the file binding device according to the present invention, it is advantageous that both the fixing plate and the cover plate are integrally formed of synthetic resin.

[Effect]

When using the file binding tool having the above-mentioned configuration, when attaching the lid plate to the fixing plate, the pressing tongue of the fitting part forcibly presses down the installed elastic wire, and the repulsive force of the elastic wire is applied. The lid plate is fixed to the fixing plate via the holding and locking means while maintaining the force that pushes the fitting part upward. Therefore, when the locking means is released, the cover plate is pushed upward at once under the action of the pushing force of the elastic wire and comes to rest at a position where it can be easily taken out. As a result, the technical problem addressed by the present invention is solved as expected.

[Embodiments of the invention]

Next, a preferred configuration example of the file binding device according to the present invention will be described in detail below with reference to the accompanying drawings.

1 and 2, the file binding device according to the present invention basically includes a flat portion 11, binding tubes 12, 12 protruding from the flat portion 11,
A fixed plate 10 consisting of a vertical portion 14 rising up from the edge of the flat portion 11 and extending, and a flat portion 15
The binding pins 18, 1 protruding from the flat portion 15
8 and a vertical wall 20 that hangs downward from the side edge of the flat portion 15.

A slit 22 is provided in the vertical portion 14, and a rigid elastic wire 24, such as a piano wire, is inserted into the slit 22 with projections 32, 3 at both ends thereof.
2, and further held at a position slightly above the projections 32, 32 from the lower side of the elastic wire by support arms 34, 34 provided near the inner sides of the projections 32, 32, so as to construct the elastic wire in a substantially arcuate shape. A pocket 27 is formed approximately at the center of the vertical wall 14, and a locking ear 25 having a rim portion 29 is flexibly installed inside the pocket 27.

On the other hand, from the lower end edge of the vertical wall 20 of the cover plate 16, a fixing plate 1 is formed with a slightly thinner wall along its longitudinal direction.
A fitting part 26 that fits into a slit 22 provided in the vertical wall 14 of 0 is extended, and a pressing tongue piece 28 for pressing the elastic wire 24 is provided protruding from the approximate center of the fitting part 26. At the edge of the vertical wall 20 opposite the piece 28 is a shoulder 31 that engages with the locking rim 29 of the locking ear 25.
form.

Next, in the embodiment shown in FIG. 3, the elastic wire 24 is held at its both ends below the protrusions 38, 38, and is further held upward by support arms 40, 40 at a position below the protrusions 38, 38. Pressing tongues 36, 36 are provided at both ends of the fitting extension 26 of the vertical wall 20 of the cover plate 16, and are opposed to both free ends of the elastic wire 24.

To explain in more detail the function of the file binding device according to the present invention configured as described above, the lid plate 1
6 to the fixing plate 10, the binding pins 18, 1
8 into the binding tubes 12, 12 and push it down all at once, the tip of the pressing tongue piece 28 comes into contact with the elastic wire 24, and pushes it down while eliminating the resistance force and simultaneously pushes the vertical wall 20. The fitting extension 26 is fitted into the slit 27 and stops at a position where the lower end surface of the vertical wall 20 abuts the upper end surface of the slit 22 (see FIG. 4). At this time, the rim portion 29 of the locking ear 25
engages with a shoulder 31 provided at the center of the vertical wall 20 of the cover plate 16, and the cover plate 16 is fixed to the fixed plate 10.

When the cover plate 16 is detached from the fixing plate 10, when the engagement between the rim part 29 of the locking lug 25 of the fixing plate 10 and the shoulder part 31 of the cover plate 16 is released, a pressing tongue piece that presses the elastic wire 24 is released. 28 is pushed upward at once by the restoring force of the elastic wire, the entire cover plate 16 is separated from the fixing plate 10, and stops rising at the position where the elastic wire 24 returns to its original position.

In the embodiment shown in FIG.
This is achieved in relation to the pressing tongues 36, 36 provided in the.

〔Effect of the invention〕

As explained above, according to the file binding device according to the present invention, the lid plate can be easily and reliably separated from the fixing plate during file work due to the relatively simple structure using elastic wire, It was possible to significantly increase the commercial value of the file binding tool.
