DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a file clip for restricting the edges of papers or the like by aligning them, and more particularly to a file clip which is simplified by minimizing the number of parts.

[0002]

2. Description of the Related Art Various types of file clips of this type have been provided. Among them, the relationship with the product of the present invention is described in JP-A-9-24687, and FIG. 6 shows a file clip thereof. The file clip shown in FIG. 6 is a resin molded product including a main body 30, a holding portion 33, and an operation lever 34. That is, the main body 30 has a substantially U-shape, and the upper piece 30a of the U-shape is set to the connection side with the pressing portion 33, and the lower piece 30b is set to the fixed side. The pressing portion 33 is connected to a corresponding portion of the upper piece 30a via the thin hinge 31, and has a substantially U-shaped (vertical piece 33a and oblique piece 33b) projecting forward and downward. The operation lever portion 34 is a portion obtained by extending the sloping piece 33b. Reference numeral 35 indicates the main body 30 as the lower piece 3.
0b is a holding plate attached via. The holding plate 35 is used as one use mode of the file clip.
Reference numerals 36a and 36b are reinforcing ribs. FIG. 6 shows a configuration in which the main body 30 and the presser portion 33 are formed separately and assembled, but the presser portion 33 may be formed integrally with the main body 30.

FIG. 6A shows a state before the paper P is sandwiched. When sandwiching the paper P from this non-sandwich mode, the ends of the paper P are aligned and inserted into the gap between the lower piece 30 b of the main body 30 and the pressing portion 33. Thereafter, by turning the operation lever portion 34 downward, that is, in the direction of arrow X2, the holding portion 33 is inverted as shown in FIG.
3b faces the lower piece 30b. The end of the paper P is the lower piece 30b
And its oblique piece 33b. This pinching force
The pressing portion 33 is proportional to the pressing force that is inverted and inserted into the U-shape of the main body 30. When the number of sheets is large and the thickness of the sheet P is large, the operation lever 34 is rotated in the direction of the upper piece 30a, that is, in the direction of the arrow X1, to push up the entire holding section 33 forward.

[0003]

The above-mentioned file clip is a resin molded product, and is light in weight and simple in structure. Therefore, it has an advantage that it can be mass-produced, can be provided at low cost, and has no problems such as rust. However, in order to enable the file clip to be sandwiched between the lower piece 30b and the oblique piece 33b even when the paper P is thin, the distance H between the upper and lower pieces 30a, 30b is set.
The perpendicular H lowered from the thin hinge 31 to the slant 33b
It is necessary to make 1 larger. In the normal state, as shown in FIG. 6 (a), the leading end side of the holding part 33 is close to the lower piece 30b, and the paper P is pressed by the holding part 33 and the lower piece 30.
b at the stage of being inserted into the gap with the paper P.
Is pressed against the tip of the shape. While maintaining the pressed state, the operation lever 34 is rotated in the direction of arrow X2, and the pressing portion 33 is rotated and inverted as shown in FIG. 6B. Accordingly, in this structure, in the process from the initial insertion state of FIG. 6A to the final holding state of FIG.
While being dragged inward from the front side. For this reason, as the sandwiching structure, when the paper quality is thin and soft, the surface is likely to wrinkle or bend easily.
In addition, the switching operation to the sandwiching mode uses the rotation reversal of the pressing unit 33 from a state in which the pressing unit 33 is pressed against the paper P. Therefore, when the number of papers increases, even if the paper ends are aligned and set, the pressing unit 33 There is a problem in that only the upper paper pressed against the front end of the main body 30 is easily moved into the U-shape of the main body 30 and is pinched in an irregular state. Moreover, since the gap between the holding portion 33 and the lower piece 30b is structurally small in the non-clamping mode, even when the number of sheets is small and thin, the operation lever portion 34 is rotated in the direction of arrow X1 when setting. There is also a problem that the gap has to be formed.

The present invention has been developed with the aim of solving all of the above problems. An object of the present invention is to provide a file clip which is made of a resin molded product, is light in weight, has a simple structure, and can be provided at a low cost, and has a more excellent clamping structure and improved usability. Still other objects will be clarified in the following description.

[0005]

According to the present invention, as shown in FIGS. 1 to 5, a substantially U-shaped main body 1 and a substantially U-shaped opening of the main body 1 are provided. Resin made of a pressing portion 5 for holding an end of paper or the like to be inserted between the U-shaped lower piece 3 and an operating lever portion 7 for switching the pressing portion 5 between a holding state and a non-holding state. In the file clip described above, the pressing portion 5 is connected to the U-shaped inner inner wall of the main body portion 1 to maintain a gap S with the lower piece 3 and to form an elastic plate longer than the U-shaped upper piece 2. On the other hand, the operating lever portion 7 is provided with a thin hinge 6 on the projecting side of the upper piece 2 of the main body 1.
And a cam 8 which is rotatably connected via a base member and which can protrude to the base end side and can push down the holding portion 5.
The pressing portion 5 is configured to be pushed down from above by the cam 8 and held in a holding state by rotating the operation lever portion 7 toward the lower piece 3.

This structure is devised so as to obtain the following advantages. In terms of the sandwiching structure, the main body 1 is located between the upper and lower pieces 2 and 3 and is connected to the inner wall of the U-shape, keeping the gap S with the lower piece 3 and being longer than the upper piece 2 of the U-shape. It has a holding portion 5 in the shape of an arrow, and an end portion of paper or the like is sandwiched between the holding portion 5 and the lower piece 3. The pinching force is a pushing-down force when the operating lever 7 is rotated via the thin hinge 6 and the pressing portion 5 is pressed downward from above by the cam 8 protruding toward the base end of the operating lever 7. It is a thing using. Therefore, according to the present invention, since the presser 5 is exclusively pressed downward from the top and switched to the clamping mode, when a large number of papers are set with their edges aligned with respect to the structure of FIG. There is no danger that the set will shift or the set state cannot be maintained. The pressing portion 5 is formed in an elastic plate shape and is pressed from above to below from the top of the paper. Therefore, even if the paper is thin and soft, the surface may be wrinkled or bent. Disappears. In addition, since the holding portion 5 is provided inside the U-shape with the gap S with the lower piece 3, as long as the thickness is smaller than the gap S, it depends on the number of sheets, that is, the thickness of the papers. The papers can be immediately inserted between the lower piece 3 and the presser 5, and the operation lever 7 can be pivotally operated. In this respect, the usability can be improved. Since the file clip itself can be realized by a single resin molded product as in the case of FIG. 6, there is no assembling work between parts, and the assembling man-hour, handling, and management are simplified. You. Further, since the sandwiching force utilizes the elasticity of the resin, there is no need to be restricted in arrangement as in the case of a spring member or to be troubled by surface treatment or the like.

The present invention is more preferably embodied as follows. First, the holding part 5 is provided on the main body part 1.
Has a locking claw 5b provided on the side facing the upper piece 2, and when the cam 8 is pushed down from above, the cam 8
Is engaged with the locking claw 5b and is held in its depressed state. In this structure, the holding state of the holding portion 5 can be reliably maintained by the engagement between the step portion 8a and the locking claw 5b. The engagement is simple because the step 8a can use one end of the cam 8 or the like, and the locking claw 5b can be a projection or the like. Even when the mode is released and switched to the non-nipping mode, the operability is not impaired. Secondly, the holding lever 5 has a hooked tip 5a formed in a curl shape, and the operating lever 7 is turned toward the upper half 2 in a state where the hooked tip 5a is hooked on the step 8a. By doing so, it is configured to be lifted in a direction in which the gap S between the lower piece 3 and the lower piece 3 is enlarged. This structure has no obstacle even when the thickness of the paper is larger than the gap S between the lower piece 3 and the pressing portion 5 when the pressing portion 5 is provided in the shape of an elastic plate in the U shape of the main body 1. It can be held smoothly. Third, the cam 8 is press-fitted between the holding portion 5 and the upper piece 2 in a state where the step 8a is engaged with the locking claw 5b so that the upper piece 2 can be pushed up. Configuration. In this structure, when papers are sandwiched between the lower piece 3 and the presser 5, the presser 5
The cam 8 is press-fitted between the holding portion 5 and the upper piece 2 to push up the upper piece 2 to obtain the repulsive force of the upper piece 2 in addition to the pressing force pressed by the upper piece 2.

In this rotation process, at the initial stage, as shown in FIG. 4A, the tapered outer surface 9a of the neck 9 is guided by the hooking tip 5a, and the projection 8b of the cam 8 elastically passes over the locking claw 5b. At this time, the holding portion 5 is slightly pushed down from above in accordance with the amount of protrusion of the locking claw 5b. When the projection 8b is fitted in the fitting groove 2a, the operation lever 7 is locked in the opposite direction by the step 8a being locked by the locking claw 5b (corresponding surface of a triangle). Is done. At this time, the holding portion 5 is largely pushed down according to the size of the cam 8. At the same time, the hooking tip 5a comes into close contact with the corresponding surface of the operation lever 7, and is regulated so as not to be inadvertently swung. In addition, with this structure, the cam 8 is engaged with the locking claw 5b via the step 8a,
Dimensions are set so that the upper piece 2 is slightly pushed up. Therefore, the pinching force
In addition to the pressing force of the pressing portion 5 pressed by the cam 8, the cam 8 is press-fitted between the pressing portion 5 and the upper piece 2, and the repulsive force of the upper piece 2 exerted by pushing up the upper piece 2 is obtained. .

FIG. 5 shows a specific example of operation for holding the end of a document or paper P. Here, in the case of FIG.
This is when the thickness t1 of the paper P is smaller than the gap S described above. At this time, the end portions of the papers P are aligned, and inserted and set directly into the gap S from the state of FIG. After that, paper P

At this time, the operation lever 7 is rotated in the direction of arrow Y3 in FIG. 5B to secure a large gap S, and then the end of the paper P is inserted and set in the enlarged gap. In this operation, since the holding portion 5 is hooked with the hooking tip 5a on the step portion 8a, when the operation lever portion 7 is rotated toward the upper piece 2 via the thin hinge 6, the gap between the lower piece 3 and the lower piece 3 is formed. It will be lifted in the direction to enlarge S. And the operation lever unit 7
After the end of the paper P is inserted and set in the enlarged gap and the rotational pressing force is released, the pressing portion 5
At a predetermined pressing force from the initial state. afterwards,
As in the case of FIG.
When the paper P is turned in the direction of arrow Y2 in FIG. 3A, the end of the paper P is pushed down by the cam 8 via the cam 8 and is held between the lower piece 3.

In any case, the holding force of the cam 8 (upper piece 2)
Between the upper piece 2 and the presser part 5, and the cam 8 is pinched by the repulsive force of the upper piece 2 which is exerted by pushing up the upper piece 2. The repulsive force of the upper piece 2 increases in proportion to the thickness t1 of the paper P. When the papers P are to be removed, for example, when the fingertip is inserted into the operation lever unit 7 from the state of FIG. 5A and the operation lever unit 7 is rotated in the arrow Y4 direction in FIG. Since the mode is switched to the non-clamping mode of FIG. 5B or the widening mode of the gap shown in FIG.
Can be pulled out. In such a structure, for example, a click feeling is obtained when switching from FIG. 3A to FIG. 3B or vice versa, or from FIG. 3B to FIG. 4B or vice versa. Can be

[0020]

As described above, the file clip of the present invention has the same advantages as those of FIG. 6 and also has a configuration in which the holding portion is switched from the upper side to the lower side to be switched to the holding mode, so that a large number of papers are When the sets are aligned, it is possible to eliminate the possibility that only the upper sheet is shifted or the set state is not maintained as in the structure of FIG. Similarly, even when the paper quality is thin and soft, it is possible to eliminate the possibility that the surface may be wrinkled or bent. Moreover, since the pressing portion is provided in the shape of an elastic plate inside the U-shape with a gap with the lower piece, the thickness of the paper is greater than the gap, depending on the number of papers, that is, the thickness of the paper. As long as the paper is small, the paper can be immediately inserted between the lower piece and the holding portion, and the operation lever can be rotated, so that the usability can be improved. For this reason, the present invention can expand the use of this type of clamping system, and improve the usability and commercial value.
