DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding device for filing, and more particularly to a binding device for binding a leaf or a clear pocket for a binder.

[0002]

2. Description of the Related Art Heretofore, in a notebook in which a perforated leaf is bundled using a ring-shaped member, a 360-degree leaf is spread using the shape of the ring.
In other words, not only opened the notebook, but also turned it back. The folded notebook was used effectively on a small desk. However, these notes have the disadvantage that the leaves cannot be replaced. On the other hand, a leaf that can be opened and closed by a comb portion that binds the leaves can be replaced. However, the back surface of these binders had a certain width due to its opening and closing mechanism. For this reason, there is a disadvantage that the leaf cannot be folded back even though the leaf can be opened by about 180 °. Here, if the width of the back part of the binder is simply made thinner, the opening and closing of the comb part becomes difficult, and in normal use, the comb part is easily opened and does not play a role as a binder. there were. In addition, as a device capable of replacing a leaf by a slide mechanism, there is a registered utility model 3010984.
No. 43-8102. However, since these require a gap for inserting a leaf, the slide mechanism cannot be made thin. for that reason,
It had the drawback that it could not be folded back like a binder that can be opened and closed. Further, the similar shape of the present invention is Japanese Utility Model Publication No. 3-6454. However, this invention differs from the present invention in that the tip of the comb portion is irremovably locked. Further, in the present invention, the comb portions are fixed to each other with a hinge, and the hinge is formed of plastic. Therefore, when the tip of the comb portion is detachable, there is a disadvantage that the hinge portion is broken by bending several times.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention
An object of the present invention is to provide a filing binding device that can replace a leaf and can also turn a leaf.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a binding device comprising two main members 1 having a plurality of comb portions 2, wherein the main members 1 are integrated. And the thickness T of the integrated main member 1 is appropriately reduced so that the leaf can be folded back, and a detachable fitting means 3 is provided at the tip of each comb portion 2.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 4 illustrates a state in which the binding device including the two main members 1 is integrated. FIG.
Represents a state where the two main members 1a and 1b are separated from each other. As shown in FIG. 5, this binding device is different from a conventional binding device, and includes a main member 1a having a comb portion 2 and a main member 1b.
Is characterized in that they are completely separated. FIG. 1 shows a state in which the main member 1a and the main member 1b shown in FIG. Here, FIG.
, The one having the ring member 4 at the tip 7 is referred to as a main member 1a, and the other is referred to as a main member 1b.

The present invention comprises two main members 1 having a plurality of comb portions 2. Here, the comb portion 2 has a semicircular ring shape as shown in the figure, and passes through a hole provided in the leaf. The shape is not necessarily limited to a circle, but an ellipse,
Further, it may have a U-shape, which is appropriately determined according to the application. The main member 1 is a substantially linear member that holds the comb.

Next, means for integrating the main members 1 of this embodiment will be described. At the tip 7a of the main member 1a,
A ring member 4 is provided. The ring member 4 includes the main member 1
It is possible to slide around the tip of a. The inner shape of the ring member 4 includes the main member 1a and the main member 1
b is substantially the same as or slightly smaller than the outer shape of the united b. By making the main member 1a longer than the main member 1b,
The recess 8 in which the tip 7b of the main member 1b fits is inserted into the main member 1
a.

Next, FIG. 2 shows a state in which the main members 1 are integrated with each other. The main members 1 are joined together so that the tip 7b of the main member 1b fits into the recess 8 of the main member 1a. Then, the ring 4 is slid to integrate the main member 1a and the main member 1b.

By providing the ring member 4 at the tip 7a of the main member 1a, the main member 1 can be integrated with a very simple structure.

Here, the surface where the main members 1 contact each other is referred to as a contact surface 9.
Then, it is desirable that one of the contact surfaces is provided with the convex portion 5 and the other contact surface is provided with the concave portion 6. This is because, when the main members 1 are integrated, the unevenness can be temporarily fixed by aligning the irregularities, so that the operation of integrating the main members 1 and the operation of fitting the comb portions 2 can be easily performed.

Further, by disposing the convex portion 5 and the concave portion 6 inside the ring member 4 after sliding, the main member 1
They are firmly integrated. In this embodiment, the mechanism of the tip 7 is provided at both ends of the main member 1 so as to be more strongly integrated.

However, in the present invention, the means for integrating the main member 1 is not limited to the method using the ring member 4 but can be implemented in various modes. For example, a mode in which the tip of the main member 1 is fixed with a belt, a mode in which a groove is provided and fitted, or a mode in which a magnet is provided in the tip 7 and this magnetic force is used, and the like.

Further, means for integrating the entire main member 1 as well as both ends of the main member 1 may be used. For example,
An embodiment in which fitting members are provided on the contact surface 9 at appropriate intervals,
This is a form in which the whole is a magnet. In the means for integrating the main member 1 as a whole, the force for integrating the main member 1 can be increased.

Next, the thickness T of the integrated main member 1 is appropriately reduced so that the leaf can be folded back. Here, the "thickness T of the main member 1" refers to the thickness T in a state where the main member 1a and the main member 1b are combined as shown in FIG. Here, FIG. 3 is a sectional view of the comb portion 2 in a state where the main members 1 and the comb portions 2 shown in FIG. 4 are integrated.

Conventionally, since the main member of the binding device has a considerable thickness (width), the binder using the binding device cannot be used by folding the leaf. Therefore, in the present invention, the thickness T is appropriately reduced so that the leaf can be folded back. here,
The word “suitable” means that it is appropriate to fold the leaf bound by this binding tool approximately 360 °, and the “appropriate thickness” means the strength of the main member 1, the size of the comb portion 2, It is determined in consideration of the thickness of the leaf to be embedded.

For example, when the main member 1 is made of a material having low strength, the main member 1 must be made thick to maintain the strength as a binding device. On the other hand, in the case of a high-strength material such as metal, the main member 1 can be made thin.

Here, for a B5 size leaf,
In the case of a binding device made of plastic, this thickness is 1.0.
It can be carried out in a range of about 5.0 mm. And
In a mode in which the strength of the main member 1 is prioritized and the leaf is made thinner, a range of about 2.0 to 5.0 mm is desirable. On the other hand, when priority is given to the ease with which the leaves are folded over the strength of the main member 1, a range of about 1.0 to 3.0 mm is desirable. Therefore, in consideration of the above, a range of about 2.0 to 3.0 mm is suitable.

In order to reduce the thickness T of the main member 1, it is not necessary that the main member 1a and the main member 1b have the same thickness, and it is sufficient if the total thickness of the two main members is an appropriate thickness. . For example, the metal main member 1a is made thinner, and the plastic main member 1b is made thicker.

Next, a description will be given of the provision of a detachable fitting means 3 at the tip of each comb portion 2. In the present invention, it is necessary to reduce the thickness T of the main member 1 so that the leaf can be folded back. However, if the thickness T is reduced, the strength of the binding device cannot be maintained.
They are easily separated from each other and cannot serve as a binder. Therefore, in the present invention, the fitting means 3 is provided at the tip of each comb portion 2 and the comb portions 2 have a holding force, thereby increasing the holding force of the entire binding device.

In this embodiment shown in FIG. 1, a spherical projection 3b is provided as a detachable fitting means 3 at the tip of the comb portion 2b of the main member 1b. And this comb part 2
A groove 3a having a width Wa that is appropriately smaller than the width Wb of the protrusion 3b is provided at the tip of the comb portion 2a of the main member 1a corresponding to b. In use, the projection 3
The holding force between the comb portions 2 is obtained by fitting b into the width 3a.

Here, the value of the "appropriately small width Wa" than the width Wb of the projection 3b is determined based on its use and material. For example, in the fitting means 3 made of plastic, the width Wa of the groove 3a can be set in a range smaller than the width Wb of the protrusion 3b by about 0.0 to 0.3 mm. In view of the holding force, ease of fitting and ease of removal, the value is desirably about 0.1 mm.

By the projections 3b and the grooves 3a, an appropriate holding force can be obtained while having an extremely simple and easy-to-make shape.
Moreover, the fitting means 3 can be detachable. Further, when the width Wa is smaller than the width Wb by about 0.1 mm, a comfortable clicking sound is heard at the time of fitting, so that the user can be informed that fitting has been achieved.

Next, the tip of the comb portion 2 in this embodiment will be described. FIG. 3A is a cross-sectional view showing a state where the comb portion 2 is fitted. Here, FIG. 3B is an enlarged view of the tip of the comb portion 2. Here, the tip surface 1 of the comb portion 2a
0a is provided with a taper so that it is slightly opened inward. The angle of this taper is defined as a taper angle θ. As a result, when the front end face 10a and the front end face 10b are fitted, a force F acts on the inside centering on the contact point 12 where both surfaces contact first. Then, the contact surface 12 is used as the center and the tip surface 1
Zeros approach each other. Finally, as shown in FIG. 3C, the distal end surface 10a comes into contact with the distal end surface 10b.

Considering the action of the force F for bringing the distal end surfaces 10 into contact with each other in the entire cross section of the comb portion 2 shown in FIG. 3A, the force F makes the main members 1 adhere to each other through the comb portion 2a and the comb portion 2b. The force F 'to be applied. Therefore, in this embodiment,
By providing a taper at the tip of the comb portion 2a, the force for integrating the main member 1 can be improved. Here, if the taper angle θ is too small, the effect of the taper cannot be obtained. On the other hand, if it is too large,
End surfaces 10 cannot contact each other. Then, when used as a binder, the tip of the comb portion 2 is likely to shift, which is not desirable. Therefore, the taper angle θ is preferably in the range of about 1 ° to 5 °, and about 3 ° is suitable.

The provision of the taper is not limited to the comb portion 2a, but may be provided on either of the comb portions 2. In addition, it may be provided on both comb portions. In that case, the angle formed between the tip surface 10a of the comb portion 2a and the tip surface 10b of the comb portion 2b may be any taper angle θ within the above range.

Further, the taper angle θ does not need to be provided on the entire distal end face 10, but may be provided only on the inside of the distal end face. For example, the distal end surface 10a is divided into two regions, an inner side and an outer side, and a straight portion is provided on the outside, and a taper portion provided with the taper angle θ is provided on the inside.

The detachable fitting means 3 may be any means capable of obtaining an appropriate holding force.
It is not limited to the mode provided with. For example, it is a means for providing a holding force by providing a magnet at the tip of the comb portion 2. Further, the projection 3a is not necessarily limited to a spherical shape, and its shape can be arbitrarily determined in consideration of the shape of the groove 3b.

Further, the fitting means 3 does not need to be provided at the tips of all the comb parts 2, and it is sufficient to arrange them appropriately according to the application. For example, of the comb portions 2, the comb portions 2 located at both ends of the main member 1 and the comb portions 2 near the center are provided with the fitting means 3, or the comb portions 2 provided with the fitting means 3 and the comb portions 2 not provided are alternately provided. It is a mode of providing. However, in consideration of increasing the holding force of the entire binding device, it is desirable that the fitting means 3 (the protrusions 3b and the grooves 3a) be provided at the tips of all the combs 2.

(How to use the binding device) Means for integrating the binding device will be described. -The concave portions 6 at both ends of the main member 1 are fitted to the convex portions 5. -The ring member 4 is slid so that the main members 1 are integrated before the comb portion 2. In a state where the main members 1 are integrated with each other, the comb portions 2 at either end are fitted with each other with fingers. If the finger holding down the fitted comb portion 2 is slid to the other unfitted comb portion 2 as it is, the other comb portions 2 can be fitted together continuously. In this way, the entire comb portion 2 can be easily fitted by fitting the comb portions 2 after the main member 1 is integrated. The means for separating the binding device will be described. Slide the ring members 4 at both ends of the main member 1 in the opposite direction. Thereby, the integration of the main member 1 is released. -Grasp the tip of the main member 7a and pull it in the direction of separating the main members 1 as they are. First, the engagement of the comb portion 2 on the pinched side of the main member 1 is released. Next, the next comb portion 2 is also disconnected continuously. -When the main member 1 is separated as it is, the two main members 1 are completely separated.

The degree of fitting of the comb portion 2 in the present invention is as follows.
It is designed to be easy to fit and easy to remove. Therefore, it is not necessary to perform a special process for releasing the fitting of the comb portion 2 itself, and it is sufficient to separate the main members 1 from each other.

[0032]

According to the binding device of the present invention, it is possible to provide a binder that can replace a leaf and can also turn a leaf. In addition, by providing the fitting means 3 at the front end of each of the comb portions 2 corresponding to the front surface together with the means for integrating the main member 1 corresponding to the back surface of the binding device, the holding force of the comb portion 2 required as a binding device can be secured. By providing the ring member 4 at the distal end 7 of the main member 1a, the main member 1 can be integrated with an extremely simple configuration. Since the temporary fixing can be performed by providing the convex portion 5 and the concave portion 6 on the contact surface 9, it is easy to integrate the main member. The protruding portion 3b and the groove 3a provide an appropriate holding force while having an extremely simple and easy-to-make shape. By providing a taper at the tip of the comb portion 2, the main member 1
It is possible to improve the force for integrating the two.
