[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an office leaf holder or a leaf binding device.

[0002]

2. Description of the Related Art A conventional leaf holder, which is also called a file or a binder, is made by punching a hole in a leaf made of paper or a polymer material, and then binding with a binding tool penetrating through the hole, or by pinching with a clip. Was there. The former is troublesome to attach and detach the leaf, and the latter is also troublesome because the entire leaf is removed and the leaf is replaced, and the alignment of the leaves is poor. It was Further, the vicinity of the binding hole of the leaf is easy to tear, and if it is attempted to reinforce the binding hole, it is likely to return due to the elastic force of the sheet, and it is difficult to maintain the open state.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a leaf holder that is easy to maintain in an open state, is easy to attach and detach, and is small and lightweight.

[0004]

The present invention is constructed as follows. (1) As shown in FIGS. 2 to 4, binding with great care binding end of the leaf that holds than is strengthened by polymeric material, the boundary vicinity linearly extending with its reinforced portion and leaf central portion To form a weak portion against bending force by perforating perforations or notches, etc. , and FIGS.
As shown in 4, the notch cut into the L shape of the leaf end
The flat cross-section binding in which the part 2 is supported by the holder back part at both ends
Leaf positioning tool on the back end of the holder that is engaged by the tool 7.
Press leaf 5 in the holder back length direction with 8
Enhancing the engagement with the flat-section binder and opening the leaf
Longer diameter of the flat cross-section binding tool 4 than the minimum gap of the mouth portion 3
And the flat cross-section binder 4 is made of rubber or polymer.
It is a material with great resilience like a material, and it is biased during use.
The flat cross section binding tool 4 bends in the flat direction, and the flat cross section binding
The direction of the long axis of the tool is almost the same as the minimum gap direction of the leaf openings.
A leaf holder characterized by a both-end support structure and material that is automatically stable .

(2) As shown in FIGS. 2 to 4, the narrow neck wide opening 3 at the leaf end is held by a flat cross section binding device 4 supported by the back of the holder, and the leaf opening 3 described above is held. The major axis of the flat cross section binder 4 is larger than the minimum distance, and the flat cross section binder is made of rubber or polymer.
It is a material with great resilience like a material, and it is biased during use.
The flat cross section binding tool bends in the flat direction, and the flat cross section binding tool
The direction of the long axis of is almost the same as the minimum spacing direction of the leaf openings
Both ends support structure and material that automatically stabilize
A leaf holder characterized by being made.

[0006]

As shown in FIGS. 2 to 4, since the binding end portion of the leaf holder is reinforced by the polymer material, it is easy to maintain the shape of the holes and openings of the binding portion in the initial state. Further, the peripheries between the reinforced portion 1 and the central portion of the leaf form perforations or notches 2 that extend linearly to form a weak portion against the bending force, so that the leaf remains open. Easy to keep

The leaf holder is structured such that the leaf is held in a state where the flat cross-section binder 4 supported by the back of the holder is inserted into the narrow neck wide opening 3 at the leaf end of the leaf holder, and the leaf can be easily attached and detached without damaging the leaf. If the major axis of the flat cross-section binding device 4 is made larger than the minimum gap of the leaf openings 3 as much as possible, the leaves 3 at the leaf end are flat when the leaf is pushed toward the back of the holder. It is pushed into the cross-section binding tool 4, and on the contrary, it can be easily removed by pulling the leaf.

When the flat cross section binder is made of a material having a large restoring property, such as rubber or polymer material, the flat cross section binder has a flat cross section, so that the leaf holder is automatically opened and used. Is positioned so that the direction of the long axis of the flat-section binder is substantially coincident with the minimum spacing direction of the leaf openings. If the flat section binder is close to a rigid body such as a metal material, if it is rotatably held by the flat binder, the direction of the long axis of the flat section binder will be the minimum of the leaf opening. It is positioned in a direction that substantially matches the direction of the spacing. In the present invention, it is possible to adopt a structure in which these directions are forcibly taken.

[0010]

[0011]

[Embodiment 3] As shown in FIGS. 2 to 3, the neck-narrow wide opening 3 at the leaf end is supported by the back of the holder at both ends thereof.
To be held by the supporting flat section binding device 4, and to have the major axis of the flat section binding device 4 larger than the minimum spacing of the leaf openings 3;
Unless it applies a special external force, the direction of the long axis of the flat cross-section binder is almost equal to the minimum gap direction of the leaf opening due to its own torsion elastic force or the torsion elastic force of the structure between itself and the fastener. Both ends support so that they match and stabilize automatically
It is a leaf holder characterized by having a holding structure and a material . In this example, even if there are no perforations, it is possible to form a straight line which is weak against the bending force only by the notch.

[0012]

Embodiment 4 In Example 3, as shown in FIG.
Narrow neck wide opening 3 is T-shaped, or back not shown
This is the case where the part has an elliptical shape.

[0013]

Example 5 As shown in FIG. 3, in Example 3, the leaf end
Narrow neck wide opening 3 is L-shaped, or back not shown
Is an elliptical shape.

[Effects of the Invention] By constructing the present invention as described above, it is possible to provide a leaf holder that is easy to maintain in an open state, is easy to attach and detach, and is small and lightweight.
