Description

[Detailed Description of the Invention] (Industrial Application Field) 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) A conventional pipe file has a board fixed to the cover, and a side plate with a pipe projecting approximately perpendicularly to the inner surface on one side edge of the board, which is biased by a spring so as to tilt outward. A locking plate is hinged to the opposite edge of the board by a spring so as to be erected from the outside to the inside, and a pin that can be inserted into the pipe of the side plate separately from these is attached. and a confinement plate provided with a protruding portion and an engagement portion with the locking plate,
After inserting the pipe into the hole drilled in the document, etc., insert the pin of the confinement plate into the pipe, and then raise the side plate against the spring to close the pipe so that it is approximately parallel to the board. The file state is completed by locking the plate and the locking plate.

(Problem to be solved by the invention) In the conventional example, the base ends of the pipes and pins are fixed to the side plate and the confinement plate by caulking or the like, and as shown in FIG. A caulking seat 7a and the like having an outer diameter somewhat larger than the outer diameter of the pipe 7 are present on the inner surface of the pipe 8. Also pipe 7
The tip of the pin 9 is usually notched diagonally to facilitate insertion of the pin 9. Therefore, both ends of the pipe 7 in the storage space for documents and the like between the inner surface of the side plate 3 and the inner surface of the confinement plate 8 are uneven due to the caulking seat 7a, the notch 7b, etc. For this reason, there was a problem that the hole 10a of the document 10 etc. could get caught in this uneven portion and the document etc. would be damaged. The primary purpose of the present invention is to solve this problem. Next, in the file state, the portions from the position of the pipe 7 to the upper edges of the side plate 3 and the confinement plate 8 are approximately perpendicular to the substrate 2, resulting in a disadvantage that the spread of documents 10 and the like is difficult. The second purpose of the present invention is to eliminate this drawback. Furthermore, a third object of the present invention is to facilitate processing for providing means for achieving the first object.

(Means for Solving the Problems) The pipe file of the present invention was devised to achieve the above-mentioned purpose, in which a board is fixed to the cover, and a pipe is attached to one side edge of the board approximately perpendicular to the inner surface. A locking plate is attached to the opposite edge of the board by a spring, and a locking plate is attached to the opposite edge of the board, and a spring urges the side plate to tilt outward from the outside. In the pipe file, the pipe file is provided with a confinement plate having a protruding pin that can be inserted into the pipe of the side plate and an engagement portion with the locking plate. The upper side of each of the confinement plates is bent outward and inclined, and a recess is formed by drawing at a required location on the inner surface including the slope, and the base end of the pipe and pin are inserted into the recess. It is characterized by being fixed by caulking or the like.

(Function) In the pipe file of the present invention, a recess is provided on the inner surface of the side plate and the confinement plate, and the base ends of the pipe and the pin are fixed in the recess by caulking or the like, so that the inner surface of the side plate and the confinement plate The resulting caulking seat etc. will be hidden within the recess. Furthermore, in the completed state of the file, the pipe tip end notch is recessed into the concave portion of the confinement plate. Next, by bending the upper sides of the side plate and the closing plate outward to provide an inclined portion, the spread of documents, etc. in the completed state of the file is improved. Furthermore, providing the sloped portions on the upper sides of the side plates and the confinement plate also facilitates the drawing process for providing the recesses on the inner surfaces of the side plates and the confinement plate.

(Example) An example will be described with reference to the drawings. A substrate 2 made of a rectangular metal plate is riveted to the inner surface of a back plate 1a of a cover 1 made of hard paper. A side plate 3 is hinged to one edge of the longitudinal side of the substrate 2, and a locking plate 4 is similarly hinged to the opposite edge of the other longitudinal side. The side plate 3 and the locking plate 4 are made of metal plates made of the same material as the substrate 2. A torsion coil spring 5 is attached to the hinged parts of the side plate 3 and the locking plate 4 relative to the board 2, so that the side plate 3 is biased to tilt toward the outside of the board 2, and the locking plate 4 is attached to the board 2. The substrate 2 is biased to stand up from the outside toward the inside of the substrate 2. Note that the board 1 to which the locking plate 4 is hinged
A support plate 6, which is integral with the base plate 2, is bent and erected at an inner position of the locking plate 4 on one side edge of the plate 2 in order to maintain the upright state of the locking plate 4. The side plate 3 has an inclined portion 3a bent outward at an appropriate angle along the upper side.
In addition, recesses 3b are formed by drawing near both ends of the inner surface including the inclined portion 3a, and the base ends of the pipes 7 are fixed by caulking inside the recesses 3b. It protrudes substantially perpendicularly to the side plate 3. Therefore, the caulking seat 7a at the base end of the pipe 7 is hidden inside the recess 3b. The tip of the pipe 7 is connected to the pin 9 of the confinement plate 8 described later.
Diagonally cut out to facilitate insertion. The locking plate 4 is provided with a hook piece 4a bent inward at the center of its upper edge in an upright state.
Similar to the side plate 3, the confinement plate 8 is provided with an inclined part 8a bent outward at an appropriate angle along the upper side, and recesses are formed by drawing near both ends of the inner surface including this inclined part 8a. 8b, and the proximal ends of pins 9 are secured to the insides of the recesses 8b by caulking, so that the pins 9 protrude substantially perpendicularly to the closing plywood 8. Therefore, the caulking seat 9a at the base end of the pin 9 is also hidden inside the recess 8b. Incidentally, the inclined portion 8a of the confinement plate 8 and the inclined portion 3a of the side plate 3 are bent from a position slightly below the center of the pin 9 and the pipe 7. The distance between the center lines of the pipes 7 on both sides of the side plate 3 and the distance between the center lines of the pins 9 on both sides of the confinement plate 8 are of course set to be the same, and the outer diameter of the pin 9 is smaller than the inner diameter of the pipe 7. Of course, the dimensions are set small. An engaging portion 8c for engaging the hook piece 4a of the locking portion 4 is provided at the center of the upper edge of the confinement plate 8. When the pin 9 of the confinement plate 8 is inserted into the pipe 7 of the side plate 3 and the pipe 7 is tilted approximately parallel to the board 2, the confinement plate 8 is located inside the support plate 6 and overlaps with it. In order to prevent the inclined portion 8a of the confinement plate 8 and the convex portion 8d protruding toward the outer surface from hitting the support plate 6 by providing the concave portion 8b on the inner surface of the confinement plate 8, the upper side of the support plate 6 is An inclined portion 6a having substantially the same slope as the inclined portion 8a on the upper side of the confinement plate 8 is provided in the section, and a cutout portion 6b is provided at a position facing the convex portion 8d of the confinement plate 8. The method of using the pipe file of this embodiment is the same as that of the conventional pipe file.

(Effect of the invention) The present invention is constructed as described above. First, a recess is provided in the inner surface of the side plate and the confinement plate, and the base end of the pipe and pin is fixed in the recess by caulking or the like. is hidden in the recess, and when the file is completed, the notch at the end of the pipe is also recessed into the recess of the confinement plate, so there are no recesses at both ends of the pipe in the storage space for documents, etc. between the side plate and the confinement plate. This eliminates the possibility of documents getting caught in the holes, thereby preventing damage to the documents. Next, it goes without saying that since the upper sides of the side plates and the closing plate are provided with outwardly inclined portions, the spread of documents, etc. is improved.
Furthermore, the presence of the inclined portion provided to improve the spread makes it easier to draw to provide recesses in the side plates and the closing plate in order to prevent damage to the documents and the like. That is, when drawing a concave part on a flat plate with no sloped part, there was a drawback that the material at the corner part 3c of the concave part stretched too much and cracks were likely to occur, as shown in FIG. By providing an inclined portion as shown in FIG. 4, the elongation of the material at the corner portion 3c of the recessed portion is suppressed, thereby reducing the possibility of cracking and thus facilitating the drawing process. This makes it possible to process the mold at low cost, and also enables high-speed press processing, making it possible to provide inexpensive products. In addition, by drawing the side plates and confinement plates where the pipes and pins are fixed, the strength of those areas is increased, so deformation is less likely to occur even when external pressure is applied, and the operability of the pipes and pins is improved. It also has the advantage of preventing deterioration of.
