Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to a binder cover in which a binding device that can be opened and closed is attached to the cover.

BACKGROUND ART Conventionally, on the inner surface of the spine of a front cover plate consisting of a front cover, a spine cover, and a back cover that are integrally arranged in a foldable manner, a large number of binding rods are spaced apart in the longitudinal direction. An operating lever is provided in the section, and a binding tool that opens and closes the binding lever by an opening/closing mechanism is attached with screws or the like so that the upper and lower ends of the spine remain, and a large number of papers, etc. can be freely attached to and removed from the binding rod. Binder covers that can be folded together to form a binder notebook are well known.

Problems that the invention aims to solve By the way, generally when you take out binder notebooks that are lined up on a bookshelf, you hook your finger on the upper edge of the spine, pull it toward you, and tilt it forward. When putting the binder notebook back into the bookshelf, the spine is tilted forward and its lower edge is brought into contact with the shelf surface, and then the binder notebook is pushed forward. Therefore, with the binder cover of the conventional structure, there is a risk that strong force will be applied to the upper and lower edges of the spine each time it is pulled out and put back in, causing damage. There is a large gap between them, and there is a risk that dust will enter and adhere to this gap, damaging the appearance. When creating a binder notebook, there was an inconvenience in that the entire cover version had to be created separately.

Means to Solve the Problem Therefore, the present application protects the spine, holds the spine between an exterior plate and an interior plate, and distinguishes the cover plate into a front cover plate and a back cover plate. This product eliminates the defects of the conventional products described above, and its gist is that it has two types: a front cover version with mounting strips integrally attached to the front cover, and a back cover version with mounting strips integrally attached to the back cover. , an exterior plate which is superimposed on the outer surface of the overlapping part where the mounting pieces are overlapped with each other, and has engaging pieces provided at the upper and lower ends thereof, respectively, which abut the upper and lower edges of the overlapping part of the mounting pieces; and the upper and lower engaging pieces. It consists of an interior board that is interposed between and overlaps the inner surface of the overlapping part, and a binding tool having a binding rod that can be opened and closed and is attached to the inner surface of the interior board, and the overlapping part of the mounting piece, the exterior board, and the interior board. It is characterized in that the binding tool is integrally fixed with a fastener in a superimposed state.

Function When creating a binder cover, a front cover version and a back cover version with different materials or colors are selected as appropriate, and a large number of binding rods of the binding tools of the binder cover created in this way are used as in the past. Binder notebooks are made up of paper, etc., and when you take them out from a shelf where they are lined up, you hook your finger on the upper engagement piece of the exterior plate and pull it toward you. It is towed and tilted forward, and when returning the binder notebook to its original position, the lower engaging piece of the exterior board contacts the shelf board while it is tilted forward, and presses it forward. .

Further, on the inner surface of the exterior plate 13, a receiving nut 16, preferably having a rectangular outer shape, which is inserted into the through holes 11 and 12 is installed. A vertically elongated index mounting portion 19 is provided into which a transparent cover 18 that overlaps is inserted. Reference numeral 20 denotes a flat, thick interior plate made of synthetic resin that overlaps the inner surface of the mounting pieces 3 and 7 in a state where they are superimposed, and a protrusion 21 that bulges toward the inner surface along the left and right edges in the longitudinal direction.
However, the engagement recesses 15 are also provided at both ends in the longitudinal direction.
An engaging protrusion 22 is provided to engage with the receiving nut 16, and a through hole 23 into which the receiving nut 16 is fitted is provided at the upper and lower positions. 24 is a long board 25
, a large number of binding rods 26 arranged along the left and right edges in the longitudinal direction, an opening/closing mechanism 27 for opening and closing the binding rods 26, and an operating lever 28 provided at the longitudinal end of the board. This is a known metal binding tool, the width of which is suitable for intervening between the protrusions 21, 21 of the interior board 20, and which is mounted at the upper and lower positions facing the receiving nut 16. A cylindrical portion 30 for insertion of a stopper 29 made of a screw is provided in a protruding manner.

Therefore, when constructing the binder cover, the mounting pieces 3 and 7 of the front cover plate and the back cover plate 5 are polymerized,
The inner surface of the exterior plate is overlapped with the outer surface of the overlapping part, and notches 9 are provided at the upper and lower ends of the mounting pieces 3 and 7.
