2. Description of the Related Art Conventionally, there has been a file tool such as a case file provided with an opening for opening and closing a document or the like with a lid. As the case file, the types shown in FIGS. 8 and 9 are known, and the case file 50 includes a flat box-shaped case main body 52 having an entrance 51 for a document or the like, and a case main body 52 of this case main body 52. A lid 54 is provided so as to be continuous with the inlet / outlet 51 side. The cover 54 has fixing holes 56, 56 formed near both ends in the longitudinal direction of the cover 54, while the fixing holes 56, 5 are formed on the free end 54 </ b> A side of the cover 54.
The intermediate holes 5 formed at intervals smaller than the mutual separation width of 6
7, 57 are formed. These fixing holes 56, 56
And a flat band-shaped rubber cord 5 between the intermediate holes 57, 57.
Each end of the rubber string 58 is fixed to a rod-shaped member 59 located on the inner surface side of the lid 54 and having a dimension longer than the diameter of the fixing hole 56.

The case file 50 has a fixing hole 56.
As shown in FIG. 9, the middle area of the rubber string 58 extending between the case body 52 and the middle hole 57 is gripped with a fingertip, and the middle area is hooked on the back side corner area of the case main body 52. The posture can be maintained, and when the hook is released, that is, in the state shown in FIG. 8, the lid 54 can be opened.

[0004]

However, as shown in FIG. 9, the conventional rubber strap 58 has the fixing hole 56 in a state where the rubber strap 58 is wrapped around the back side corner region of the case main body 52. In a state where the rubber string 58 is extremely bent at the formation edge, the rubber string 58 will bite strongly. Therefore, each time the looping operation and the loop release operation of the rubber string 58 are repeated, the rubber string 58 rubs against the forming edge of the fixing hole 56 with the rotational movement along the surface of the lid 54. Will happen. For this reason, such friction causes an inconvenience that the rubber string 58 is easily cut.

Is inevitable, not only is production efficiency inferior,
The inconvenience that the rubber string 58 falls off from the rod-shaped member 59 due to repeated continuous pulling of the rubber string 58 also occurs.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of such inconvenience, and an object of the present invention is to cut an elastic cord so as not to rub against a forming edge of a fixing hole. To provide a support structure for a rubber string in a file tool, which can avoid the cause and further integrally form an end area of the rubber string to be hooked on the fixing hole, thereby achieving a dramatic improvement in manufacturing efficiency. It is in.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a cover or a cover in which documents or the like can be accommodated or bound, provided with two fixing holes, and rubber holes formed in these fixing holes. In the support structure for a rubber cord in a file tool for restricting the opening of the cover or the cover by hanging the middle area of the rubber cord at a predetermined position while penetrating both ends of the cord and fixing the rubber cord, Is
A cord body extending along the surface of the lid or cover,
A hook provided at both ends of the string main body and hooked around the fixing hole is provided, and the string main body is provided with a diameter substantially equal to or larger than the diameter of the fixing hole and inserted into the fixing hole. , Is adopted.

The rubber cord according to the present invention comprises: a cord body extending along the surface of the cover or the cover; a large-diameter portion provided at both ends of the cord body and located in the fixing hole; It is also possible to adopt a configuration comprising a hook provided at the tip of the large diameter portion and hooked around the fixing hole in a direction intersecting the axis of the large diameter portion. According to such a configuration, the cord body or the large diameter portion is inserted so as to fill the inner space of the fixing hole,
When performing the hanging work and the hanging release work of the cord body,
The string main body portion and the large diameter portion in the fixing hole are kept stationary without substantially rotating. Therefore, there is no rubbing between the fixing edge and the forming edge of the fixing hole as in the related art, and this can eliminate the cause of the cutting of the rubber cord at the fixing hole position. The support structure of the elastic cord can be used.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION It is preferable that the hanging portion in the present invention is formed integrally with a cord body or a large diameter portion. This eliminates the conventional work of fixing the rod-shaped member to the end of the rubber cord, and can improve manufacturing efficiency.

[0009] The hanging portion may be composed of a long portion and a short portion having lengths that are asymmetric about the axis of the cord body or the large diameter portion. At this time, it is preferable that the long portion is provided thicker than the short portion. With such a configuration, it is possible to secure a necessary length for hooking the hanging portion around the fixing hole, but after the hanging portion is forcibly inserted into the fixing hole, the hanging portion becomes the fixing hole. Can be prevented from inadvertently coming out of the device.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view of a case file to which a support structure for a rubber cord according to the present invention is applied. In this figure, the case file 10 has substantially the same configuration as the conventional example. That is, it is configured to include a flat box-shaped case main body 12 having an access port 11 and a lid 14 provided so as to be continuous with the access port 11 side of the case main body 12. The cover 14 has fixing holes 16 near both ends in the longitudinal direction of the cover 14.
On the other hand, on the free end 14A side of the lid 14, intermediate holes 17, 17 formed at intervals smaller than the mutual separation width of the fixing holes 16, 16 are formed. Although not particularly limited, a rubber cord 18 having a substantially circular cross section is wound between the fixing holes 16 and 16 and the intermediate holes 17 and 17.

In the present embodiment, the rubber cord 18 is formed using silicone rubber as a molding material. This rubber cord 1
As shown in FIGS. 4 to 7, the cover 8 is provided between the fixing holes 16, 16 via the intermediate hole 17.
A string body 20 extending along the outer surface of the string body, a large-diameter portion 21 provided at both ends of the string body 20 and provided slightly thicker than the diameter of the string body 20, and a large-diameter portion 21 provided at the tip of the large-diameter portion 21. And a hook portion 22 oriented in a direction substantially orthogonal to the axial direction of the large-diameter portion 21. The diameter of the large-diameter portion 21 is provided slightly larger than the inner diameter of the fixing hole 16, so that the large-diameter portion 2
1 is inserted into the fixing hole 16 and the fixing hole 1
6 so that the entire circumference of the large-diameter portion 21 can be firmly accommodated in the state of biting.

As shown in FIGS. 3 to 7, the hook portion 22 has a substantially annular hooking surface 25 on the inner surface side of the lid 14 which is in contact with the periphery of the fixing hole 16. 4, a long part 27 and a short part 2 which extend straight in the left-right direction in FIG.
8, whereby the hanging portion 22 is provided in an asymmetric shape with the axis of the large-diameter portion 21 as a center. Here, the long part 27 and the short part 28 have flat surfaces 27A and 28A on the upper surface side in FIG. 4 so as to be in close contact with the inner surface of the lid 14. Further, as is clear from the comparison of FIGS. 5 and 6 shown on the same scale, the long portion 27 is provided in a shape that is thicker in the lateral direction than the short portion 28, and thereby, the While allowing the intentional insertion and removal of the hanging portion 22, even if the cord body 20 is hung on the back side of the case body 12 and receives a pulling force, the hanging portion 22 can easily be fixed to the fixing hole 16. It does not get out of the way. In addition, the short portion 28 is shown in FIG.
As shown in FIG. 3, the upper and lower portions are formed in a shape having an inclined surface 28B whose upper and lower wall thicknesses on the tip side with respect to the central portion 26 become gradually thinner.

In the above configuration, the rubber string 18 is
In the case of mounting on the mounting portion 4, the hanging portion 22 is inserted into the fixing hole 16 with the long portion 27 of the hanging portion 22 as a tip. Then, with the elongated portion 27 slightly protruding toward the inner surface side of the lid 14, the portion may be pinched and strongly pulled. Thereby, the hanging part 2
2 and the large-diameter portion 21 are deformed so as to temporarily overlap with each other, and forcibly contracted by the inner diameter of the fixing hole 16 to pass through the fixing hole 16. Then, after the hook portion 22 has completely passed through the fixing hole 16, the cord body 20
Is pulled in the opposite direction to the above, so that the hooking surface 25 of the central portion 26, the respective flat surfaces 27 of the long portion 27 and the short portion 28
A and 28A come into close contact with the inner surface of the lid 14, so that the end fixing of the rubber cord 18 can be completed.

In a state where such a mounting work is completed,
When the work of hanging the string main body 20 around the back side corner region of the case body 12 and the work of releasing the same are performed, the string main body 2
0 moves within the plane of the lid 14, but since the large diameter portion 21 is formed larger than the diameter of the fixing hole 16, the large diameter portion 21 is cut into the fixing hole 16 and becomes fixed. It does not rotate in the hole 16.

Therefore, according to this embodiment, it is possible to effectively prevent the risk of cutting due to friction with the forming edge of the fixing hole as seen in the conventional example.

In the above-described embodiment, the case where the support structure of the rubber cord is applied to the case file 10 has been illustrated and described. However, the present invention is not limited to this. The present invention can also be applied to a file in which one end of a rubber cord is supported on one cover and the other end is wrapped around the other cover. The rubber cord 18 is not limited to silicon rubber, but may be made of another material as long as it has an applicable elasticity.

In the above-described embodiment, the rubber cord 18 having the large diameter portions 21 at both ends of the cord main body 20 is shown. However, the cord main body 20 is made substantially the same as or larger in diameter than the fixing hole 16. It is also possible to adopt a configuration in which the fixing holes 16 are provided and inserted into the fixing holes 16.

[0019]

As described above, according to the present invention,
Both ends or the large-diameter portion of the cord main body are inserted in a state in which both ends or the large-diameter portion are in close contact with each other so as to fill the inner space of the fixing hole. It will be kept stationary. Therefore, there is no rubbing between the forming edge of the fixing hole as in the prior art, and the cause of cutting the rubber cord at the fixing hole position can be eliminated. It is possible to provide a support structure for a rubber string that can provide an excellent effect that has not been achieved in the past.

Further, since the hanging portion is integrally formed with the cord main body or the large diameter portion, the work of fixing the rod-shaped member to the end of the rubber cord as in the prior art is eliminated, and the production efficiency can be improved.

Further, in the configuration in which the hook portion is constituted by a long portion and a short portion, and the long portion is provided thicker than the short portion, the necessary length for hooking the hook portion around the fixing hole is provided. On the other hand, it is possible to prevent the hanging portion from accidentally falling out of the fixing hole after the hanging portion is forcibly inserted into the fixing hole.
