TECHNICAL FIELD OF THE INVENTION
The present invention relates to a file binding device (ring binder) used for binding papers, and more particularly to a file binding device with improved safety in use.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a file binding device called a ring binder has been known for binding papers and has been widely used. This consists of a pair of left and right operating plates with half-split rings attached inside a body frame with spring properties, and a trigger for bending the operating plate attached to both ends in the longitudinal direction of the body frame. Is done.
[0003]
According to this type of file binding device, a binding ring for binding papers can be opened and closed by a bending operation of an operation plate by a trigger.
[0004]
An example is shown in FIG. 9 where F is a main body frame, R and R are half-split rings protruding toward the front side of the main body frame, and P and P are a pair of left and right operation plates to which a stitch ring is attached. In addition, a horizontally long slit S is formed at the center of the end of the operation plate P. Further, T is a J-shaped trigger. The trigger T has a front end as a head portion h inserted between the main body frame F and the operation plates P, P, and fits into the slit S below the head portion. The neck part n is formed.
[0005]
Therefore, the trigger T is prevented from falling off by the slit S. However, in the binding device as shown in FIG. 9, the trigger T is sandwiched between the operating plates P, P, and in this state, both must be integrated with the main body frame F. Therefore, the assembling work is not easy, and the trigger T is held only by the slit S, so that there is a disadvantage that the trigger T is apt to rattle.
[0006]
Therefore, a binding device as shown in FIG. 10 has been put to practical use. This binding device is configured such that concave notched grooves M1 and M2 are formed in the center of the end portions of the main body frame F and the operating plates P and P, respectively, and the trigger T is inserted into the notched grooves M1 and M2.
[0007]
In particular, according to the binding device as shown in FIG. 10, the main body frame F and the operating plates P, P are integrated, and then the trigger T is inserted into the cutout grooves M1, M2. The trigger T is attached by crimping both side edges e, e of the main body frame F as shown. According to this, since the trigger T is held by the notch grooves M1 and M2 and the caulking portions e and e, the trigger T does not rattle and can be easily mounted.
[0008]
[Problems to be solved by the invention]
However, according to the conventional file binding device as shown in FIGS. 10 to 12, the caulking portions at both ends of the main body frame become flaky and protrude from the cover of the file book. There was a risk of being injured by being scratched by the caulked portion.
[0009]
In addition, since the swaged portion protrudes, the overall length of the file binding device becomes longer than the size of the paper, which may cause a problem that the swaged portion protrudes to the outside when attached to a fixed-size cover. was there.
[0010]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a file binding device that is highly convenient and safe in use.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a pair of left and right operating plates each having a half-split ring attached to a main body frame having spring properties, and has both side edges at both longitudinal ends of the main body frame. In a file binding device in which a trigger for performing the bending operation of the operating plate is mounted and the binding ring is opened and closed by the bending operation of the operating plate by the trigger, the trigger is disposed between the main body frame and the operating plate. A head portion interposed in the main body frame, a mounting portion facing the end surface of the operation plate, and an operation portion rising on the surface side of the main body frame, a lower portion of the operation portion covers an end surface of the main body frame, The frame is characterized in that both side edges thereof are caulked between the mounting portion of the trigger and the operation portion.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, application examples of the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view of a file binding device according to the present invention, FIG. 2 is a side view of the same, and FIG. 3 shows a cross section taken along line XX in FIG. In these figures, reference numeral 1 denotes a long body frame formed by processing a metal plate to impart spring properties. The body frame 1 has a flat C-shaped cross section and has cylindrical clasps on both sides at the top. 2 is provided. The clasp 2 is for fixing the entire binding device to the back of a cover (not shown). One end of the clasp 2 is fixed to the top of the surface of the main body frame 1, and the other end is a pair of left and right operating plates 3, described later. 4 and protrudes downward therefrom.
[0013]
The operation plates 3 and 4 are hinge-shaped metal plates that bend each other by engaging the inner edges 3A and 4A, and are provided inside the main body frame along the longitudinal direction of the main body frame 1, The outer edges 3B, 4B are elastically supported by the body frame 1.
[0014]
Also, the operating plates 3 and 4 are attached at predetermined intervals to form a half-split ring-shaped binding ring 5 or 6 so as to rise up to the surface side of the main body frame 1. A long hole 7 for passing the same 6 is formed. The binding rings 5 and 6 are binding metal fittings that pass through holes formed in the paper, such as loose leaves, and one ends of the binding rings are firmly fixed to the operation plates 3 and 4, and one ends on the upper side are abutted to each other as free ends. In particular, the binding rings 5 and 6 are adapted to open and close abutting portions in conjunction with the operating plates 3 and 4.
[0015]
Reference numeral 8 denotes a trigger for bending the operating plates 3 and 4 to open and close the binding rings 5 and 6. The trigger 8 is swingably attached to both longitudinal ends of the main body frame 1, and is in an upright state in normal times. When the bindings 5 and 6 are closed and tilted outward, the bindings 5 and 6 are opened.
[0016]
That is, when the trigger 8 is in the upright posture as shown in FIG. 3, the operating plates 3 and 4 form a V-shape and the closed state of the binding rings 5 and 6 is maintained, but the trigger 8 is tilted outward. Then, the operation plates 3 and 4 become inverted V-shape against the elasticity of the main body frame 1, whereby the binding rings 5 and 6 are opened as shown by the imaginary line in FIG.
[0017]
FIG. 4 is a perspective view showing the trigger. As is apparent from this figure, the trigger 8 has an upper horizontal portion which has an operating portion 9 having a pair of left and right protruding pieces 9A and 9B on its main surface, and which extends substantially perpendicularly to the operating portion 9 between the protruding pieces 9A and 9B. 10, a horizontally long mounting portion 11 that bends at a right angle below the tip of the upper horizontal portion, a lower horizontal portion 12 that extends substantially at a right angle to the center of the lower edge of the mounting portion, and a tip of the lower horizontal portion is bent obliquely upward. In addition to forming the raised slope portion 13, an oblong head portion 15 is formed at the tip of the slope portion 13 via a narrow neck portion 14.
[0018]
In particular, the width of the lower portion of the operation portion 9 (the distance between the protruding pieces 9A and 9B) is substantially equal to the width of the main body frame 1, and the mounting portion 11 has the same shape as the internal shape of the main body frame 1 and has a long length. The height is set substantially equal to the inner diameter width of the main body frame 1. In addition, the trigger 8 is formed by bending a metal plate to integrally form the above-described parts. However, it is preferable that the periphery is rounded by polishing or the like from the viewpoint of safety.
[0019]
When the trigger 8 is tilted, the upper edges of the slopes 13 press the inner edges 3A and 4A of the operating plates 3 and 4 near the lower side so that the operating plates 3 and 4 bend in an inverted V-shape. When the trigger 8 is returned to the upright posture, the lower edges of the head portion 15 press the inner edges 3A and 4A of the operating plates 3 and 4 closer to each other, so that the operating plates 3 and 4 bend in a V-shape. However, when the operating plates 3 and 4 are bent in a V-shape, an operating force in the closing direction may be applied to the binding rings 5 and 6 in the open state.
[0020]
On the other hand, as shown in FIG. 5, the longitudinal ends of the operation plates 3 and 4 (only one end is shown in FIG. 5) are provided with concave notches 16 around the adjacent inner edges 3A and 4A. Is formed. After the operation plates 3 and 4 are incorporated into the main body frame 1, the trigger 8 is disposed at both ends of the main body frame 1 by inserting the neck portion 14 into the cutout groove 16 from the outside.
[0021]
Thus, in a state where the triggers 8 are arranged at both ends of the main body frame 1, the head portion 15 is interposed between the main body frame 1 and the operation plates 3 and 4 as shown in FIG. , 4, the upper horizontal portion 10 extends along the back surface of the main body frame 1, and the operation portion 9 rises substantially perpendicularly to the front surface side of the main body frame 1. As shown in FIG. 7, both side edges 1A and 1B of the main body frame 1 are caulked in the thickness direction of the main body frame 1 between the mounting portion 11 of the trigger and the operation portion 9, and the caulking portions 1A and 1B are provided. Both sides of the mounting portion 11 are sandwiched between the end portions of the operating plates 3 and 4.
[0022]
For this reason, the trigger 8 is swingably attached to both ends of the main body frame 1 without falling off. In particular, when the trigger 8 is mounted, the lower part of the operation portion 9 forming the projecting pieces 9A and 9B covers the end face of the main body frame 1 as shown in FIG. Therefore, when the file book provided with the file binding device is taken out of the bookcase, the fingertip is not injured at the end face of the main body frame 1 including the caulked portion. The caulking of both side edges 1A and 1B is performed by crushing the relevant portion from the back side of the main body frame 1 using a pressing device or a predetermined tool.
[0023]
Although the present invention has been described above, the file binding device is not limited to the illustrated example, and for example, a large number of binding rings 5 and 6 may be provided at predetermined intervals in the longitudinal direction of the main body frame 1.
[0024]
【The invention's effect】
As is clear from the above description, according to the present invention, a pair of left and right operating plates each having a half-split ring attached thereto are provided in a main body frame having spring properties, and both end portions in the longitudinal direction of the main body frame are provided at both ends. In a file binding device in which a trigger for crimping an edge to perform a bending operation of an operation plate is attached and the binding ring is opened and closed by the bending operation of the operation plate by the trigger, the trigger is located between the main body frame and the operation plate. And a mounting portion facing the end face of the operation plate, and an operation portion rising on the front side of the main body frame, a lower portion of the operation portion covers an end face of the main body frame, and the main body frame is a trigger. Since the both side edges are caulked between the mounting portion and the operating portion, the caulking portions do not protrude at both ends in the longitudinal direction of the main body frame, and safety in use is greatly improved.
[0025]
In addition, since the caulking portion does not protrude, the entire length of the file binding device can be made to be substantially the same as the size of the sheet, and can be completely accommodated in the cover sheet of the standard size.
