Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a method commonly called pipe file, in which a pipe is inserted into a hole drilled in a document, etc., and then bound.

(Prior Art) An example of a conventional pipe file includes a substrate fixed to a cover body, a side plate rotatably fixed to one side edge of the substrate and biased by a spring in a direction to fall outward. A pipe that protrudes from the inner surface of the side plate and has an open tip, a holding plate that protrudes with a binding pin that can be inserted into the pipe, and is rotatably fixed to the other side edge of the board facing the side plate. There is a pipe file which is provided with a retaining plate in which a binding pin is inserted into a pipe which is biased by a spring in a direction that stands up inward substantially perpendicularly to the cover body, and a retaining plate that engages and fixes the pipe.

(Problems to be Solved by the Invention) In such conventional pipe files, a holding plate is used to facilitate the insertion and removal of intermediate documents such as documents fixed to the pipe. In other words, the group of documents that are above the documents to be inserted and removed is pulled out from the pipe together with the binding pin of the holding plate, and after the insertion and removal work is completed, the binding pin of the holding plate holding the group of documents is inserted into the pipe again. It is inserted. However, with a pipe file having such a structure, even when a new document is added to the top of the document and fixed, the presser plate must be similarly removed from the pipe. With this invention, there is no need to remove the holding plate from the pipe when adding a new document, and documents in the middle can be easily inserted and removed using the holding plate in the same way as before, making it extremely user-friendly. The purpose is to provide quality pipe files.

(Means for Solving the Problems) The pipe file of the present invention devised to achieve the above object includes a substrate fixed to the cover body,
A side plate that is rotatably attached to one side edge of the board and biased by a spring in the direction of falling outward, a pipe that protrudes from the inner surface of the side plate and has an open end, and a pipe that can be inserted into the pipe. A retaining plate with a protruding binding pin and a fitting that is rotatably fixed to the other side edge of the base plate at a position opposite to the side plate, is biased by a spring in the direction of rising inward, and the tip of the pipe is inserted into it. A retaining plate provided with a hole is provided, and a retaining portion for the binding pin of the presser plate is provided on the base plate, so that the binding pin of the presser plate can be selectively fixed to the pipe or the holding portion of the base plate. It is what it is.

(Embodiment) The illustrated embodiment includes a rectangular metal substrate 2 riveted to a cover body 1, and a hinge portion 3 whose lower edge is hinged to one edge of the long side of the substrate 2. A side plate 5 is biased by a torsion coil spring 4 attached to the torsion coil spring 4 to rotate outward and lie face down on the cover body 1, and a side plate 5 protrudes approximately perpendicularly to both lateral sides of the inner surface of the side plate 5. A pair of pipes 6 are provided with open ends, and a pair of binding pins 7 that can be inserted into the pipes 6 are provided approximately vertically on both sides, and an arm bent approximately vertically is provided at the base end of the binding pins 7. 8 is provided so that the arm 8 is rotatable, and the distance between the binding pins 7 on both sides can be changed by rotating the arm 8. The distance is set to be the same as the distance between a pair of holding holes 9 of the binding pin 7 provided on the base plate 2, which will be described later, and a groove 10 is provided in which the arm 8 engages in order to fix its posture. When rotated approximately 90 degrees and facing the position approximately parallel to the lower edge, both binding rods 7
The holding plate 11 is dimensioned so that the distance between the two pipes 6 is the same as the distance between both pipes 6, and the holding plate 11 is provided with a groove 10' in which the arm 8 engages in order to fix the posture as before, and the side plate 5. A notch 1 is integrally provided with the substrate 2 and stands perpendicularly to the substrate 2 on the other side edge opposite to one side edge of the substrate 2 to which the substrate 2 is fixed.
2, and the wall plate 13 is arranged at a position corresponding to the notch 12 on the outer surface side of the wall plate 13, and its lower edge is hinged to the lower end of the wall plate 13 and attached to the hinge part 3'. The engaging hole 14 is biased in a direction to stand up close to the outer surface of the wall plate 13 by the torsion coil spring 4', into which the tip of the pipe 6 described above is fitted.
The binding pin 7 of the above-mentioned presser plate 11, which is substantially perpendicular to the wall plate 13 and opens on the outer surface of the wall plate 13, can be inserted into both lateral ends of the base plate 2. A holding hole 9 is provided along the cover body 1.

(Operation) The operation will be explained below based on the drawings. Figures 1 and 2 show a state in which a new document A is added on top of an already held document A, and the presser plate 1
1 is disposed on the outer surface of the wall plate 13 and the hanging plate 15, and the binding pin 7 is inserted into the holding hole 9 of the base plate 2. Next, FIG. 3 shows the state in which the document A in the intermediate section is inserted and removed. The binding pin 7 is inserted into the pipe 6, the presser plate 11 is attached to the tip of the pipe 6, and the document to be inserted and removed is inserted into the pipe 6. The group of documents A stacked on top is held on the presser plate 11 and is once removed from the pipe 6, and after the documents have been inserted and removed, the presser plate 11 holding the group of documents A is attached to the pipe 6 again. A group of documents A is fixed to the pipe 6 all at once. 4 and 5 show the state of the file, in which the holding plate 11 is removed from the pipe 6 and placed on the outer surface of the hanging plate 15, and the binding pin 7 is attached to the board 2.
The pipe 6 is inserted into the holding hole 9 of the board 2, the side plate 5 is erected, the pipe 6 is laid down substantially parallel to the base plate 2, and its tip is inserted into the engagement hole 14 of the engagement plate 15 to be engaged. Of course, to eliminate the locked state, the locking plate 15 may be tilted outward to release the locked state between the pipe 6 and the engaging hole 14. Furthermore, even when the presser plate 11 is positioned on the outer side of the locking plate 15, there is a margin to allow the locking plate 15 to be tilted slightly outward, so that it is possible to release the locked state between the pipe 6 and the hooking hole 14. .

(Effects of the invention) As described above, the present invention allows new documents to be added by attaching the binding pin of the holding plate to the holding part of the board and placing the holding plate on the outside of the hanging plate. Eliminates the hassle of removing the presser plate from the pipe each time.
Further, when inserting and removing documents from the intermediate portion, the holding plate can be fitted to the tip of the pipe as in the conventional case, and this can be easily done, resulting in the effect of greatly improving usability.
