Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to improvement of pipe files.

(Prior art) As shown in Fig. 4, the conventional pipe file is
A side plate 4 having a pipe 3 with an open end protruding approximately perpendicularly from the inner surface on one side of a substrate 2 fixed to the cover 1;
A pipe file main body 6 is formed by hingedly movable up and down, and a locking plate 5 is similarly hinged to the other side edge of the base plate 2 so as to face the side plate 4, and a pin 7 is attached approximately perpendicularly to the inner surface. The pipe 3 of the pipe file main body 6 is inserted into the document binding hole, the document is held by the pipe 3, and then the pin 7 of the binding plate 8 is inserted into the pipe 3. The structure is such that the pipe 3 is laid down substantially parallel to the base plate 2 while documents are prevented from being pulled out, and the binding plate 8 is locked and fixed by the locking plate 5. The tip is cut almost diagonally so that it can be easily inserted into the document storage hole and the pin 7 of the binding board 8 can be easily inserted.

(Problem to be solved by the invention) If the tip of the pipe 3 is cut diagonally as described above, when the pin 7 of the binding plate 8 is inserted into the pipe 3, the tip of the pipe 3 and Since a gap 9 is formed between the bases of the pins 7 on the plate 8, there is a possibility that documents may get caught in this gap 9 and be damaged. The object of the present invention is to provide a pipe file that solves these problems.

(Means for solving the problem) The pipe file of the present invention devised to achieve the above object has an opening at one side of the substrate fixed to the cover, and the end is cut diagonally. A pipe file main body is formed by hingedly extending a side plate with a pipe projecting approximately perpendicularly from the inner surface, and a locking plate similarly hinged to the other edge of the substrate so as to face the side plate, and an inner surface. It is equipped with a binding plate with a pin protruding almost vertically from the pipe file body, and after inserting the pipe of the pipe file main body into the document binding hole and holding the document, the pipe is inserted with the pin of the binding plate inserted into the pipe. In the pipe file configured such that the binding board is held by the locking plate by tilting the board approximately parallel to the base plate,
This is characterized in that the base of the pin in the binding plate is provided with a hole or a recess deep enough to allow the diagonal cut portion of the tip of the pipe to completely immerse therein.

(Example) An example of the present invention will be described below based on FIGS. 1 to 3. The pipe file main body 6 is fixed with its base plate 2 riveted to the inner surface of the spine of the cover 1. A side plate 4 is hinged to one side edge of the board 2 so as to be able to rise and fall freely with respect to the cover 1, and a torsion coil spring 10 is attached to the hinge portion, so that the side plate 4 is attached to the board 2.
The cover 1 is biased in the direction of facing down onto the inner surface of the outer cover 1. A pair of pipes 3, each having an open tip and an obliquely cut inner side, protrudes substantially vertically from both ends of the inner surface of the side plate 4. On the other hand, on the other side edge of the substrate 2, a wall plate 11 integral with the substrate 2 is bent approximately perpendicularly so as to face the side plate 4, and is provided with grooves at both ends of its upper edge. 12 is cut out. A locking plate 5 is disposed on the outside of the wall plate 11, the lower edge of the locking plate 5 is hinged, and a torsion coil spring is attached to the hinge, so that the locking plate 5 stands up and the wall plate 11 is biased in the direction of polymerization toward the outer surface of the At both ends of the upper edge of the locking plate 5, the wall plate 1
A locking piece 13 bent toward the inner surface is provided at a position corresponding to the first groove 12. The binding plate 8 has a circular recess 15 at both ends of its inner surface, the inner diameter of which is larger than the outer diameter of the pipe 3 and deeper than the axial length of the diagonal cut portion 14 at the tip of the pipe 3. The base of the pin 17 is fixed inside the recess 15. Note that the recess 1 on the inner surface of the outer surface of the binding board 8
A protrusion 16 is formed at a position corresponding to 5.

(Operation) The operation will be explained based on the above embodiment. First, as shown in Fig. 1, with the tip of the pipe 3 open, the pipe 3 is inserted into the document storage hole to hold the document, and then the pin 7 of the storage board 8 is inserted into the pipe 3, and the side When the pipe 3 is made to stand up against the torsion coil spring 10 and the pipe 3 is brought down substantially parallel to the base plate 2, the binding plate 8 is in a position to overlap with the inner surface of the wall plate 11, and the binding plate 8 is The protrusion 16 on the outer surface protrudes from the groove 12 to the outer surface of the wall plate 11 and locks the locking plate 5.
The locking piece 13 covers and locks the upper surface of the protrusion 16, and the stowed state is completed as shown in FIGS. 2 and 3. In this state, the diagonal cut portion 14 at the tip of the pipe 3 is completely recessed into the recess 15 present at the base of the pin 7 of the binding plate 8. Therefore, the gap between the diagonal cut portion 14 at the tip of the pipe 3 and the inner surface of the binding plate 8 disappears, and documents are no longer caught.

(Effects of the invention) The present invention is as described above, and has the effect of preventing documents from getting caught due to the diagonal cut portion at the tip of the pipe, thereby preventing damage to the documents.
