Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in files, particularly in their binding tools.

Conventional file storage tools, especially those of the type that allow the pin body to be raised and lowered to attach and remove files,
Since the pin bodies must be able to raise and lower and move freely in the lateral direction, each pin body has to be raised manually in many cases, which is cumbersome in terms of operation. Furthermore, if a spring or the like is attached to each pin body to automatically raise the pin body, the structure becomes complicated and becomes a factor in increasing costs.

The object of the present invention is to provide a file equipped with a binding tool that has a simple structure and allows each pin body to automatically stand up and move laterally.

The present invention consists of a support body in which a support shaft with a rectangular cross section is installed between both side plates, a locking hole in the side wall part, and a rectangular mounting hole, so that the support shaft cannot rotate in the axial direction. consists of a required number of sliding pieces that are slidably attached, the base end of which is rotatably attached to the support shaft inside the sliding piece, and a spring body is energized between the sliding pieces and the sliding piece. and a pin body having a protrusion that engages with the locking hole of the sliding piece, and the binding tool is configured at least one end of the inner surface of the spine section of the cover body. This aims to achieve the above objectives.

The drawings show embodiments of the present invention, which will be described below with reference to the drawings.

A support 5 having a support shaft 4 with a rectangular cross section installed between both side plates 3 and 3' is fixed to one end of the inner surface of the spine section 2 of the cover body 1, and a required number of sliding pieces are mounted on this support shaft 4. 6 is fitted so as to be unrotatable but slidable in the axial direction. That is, the sliding piece 6 has both side walls 7, 7' and a bottom wall 8, and the both side walls 7, 7' have rectangular mounting holes 9,
9' is opened and the support shaft 4 is inserted therethrough, and rotation is made impossible by the engagement of the corners. Also, locking holes 10, 10' are provided in the side walls 7, 7' of the sliding piece 6. This sliding piece 6
A pin body 11 has its base end 12 rotatably attached to the support shaft 4 between both side walls 7 and 7', and the inner surface of the pin body 11 and the bottom wall 8 of the sliding piece 6 are connected to each other. A tension spring 13 is biased between the two and the center portion is wound around the support shaft 4. The biasing direction of the spring 13 is the direction in which the long tip portion 14 of the pin body 11 is made to stand up upward. Moreover, the base end 1 of the pin body 11
The locking holes 10, 1 for the sliding piece 6 are provided on the outer surface of the slide piece 2.
0' are provided with engageable protrusions 15, 15'. The binding tool 16 is constructed as described above, and its function is as follows. First, an object to be filed is placed on the upper surface of the cover body 1 with the pin body 11 in an upright state. Next, when the pin body 11 is laid down against the spring force of the tension spring 13, the protrusion 1 of the base end 12
5 and 15' are fitted into the locking holes 10 and 10' of the sliding piece 6, and the pin body 11 is locked in the down position.
In this state, one end of the object to be filed is pin body 1.
1 and the cover body 1. To release this state, press the pin body 11 a little further and the protrusions 15, 15' of the pin body 11 will come out of the locking holes 10, 10' of the sliding piece 6. After that, if you release your hand, the pin body 11 can be automatically erected by the tension spring 13.

A separate binding tool 17 is provided at the other end of the inner surface of the spine section 2 of the cover body 1, and this binding tool 17 will be briefly explained below. That is, a support body 24 having both inner and outer side surfaces open and a horizontal hole 19 formed in the upper surface 18 is fixed to the cover body 1, has a long piece part 20 and a folded piece part 21, and has a long piece part side on the folded piece part 21. A required number of pin bodies 23 are provided with protrusions 22 to the support body 24 , and the pin bodies 23 have their folded pieces 21 inserted into the support body 24 . top surface 18
is clamped, and the protrusion 22 of the folded piece part 21 is fitted into the horizontal hole 19 of the upper surface 18 to be locked. It is used to clamp the other end of the object to be filed.

The present invention has a simple structure as described above, and by slightly pressing each pin body, the engagement between the protrusion and the locking hole of the sliding piece is released, and the spring body automatically makes it stand up. Since the pin body can be made to slide freely in the lateral direction, it is possible to provide a file equipped with a binding tool that is low in cost and has excellent usability.
