Description

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

Conventional file binding tools, particularly those of the type that clamp objects to be filed using pin bodies, generally have a pin body that rises and falls up and down when attaching and removing objects to be filed. Therefore, when the pin body is in an erect state, the tip of the pin body faces upward, which is dangerous for the user, so care must be taken.

The purpose of this invention is to ensure the safety of the user by having the pin body slide back and forth instead of undulating it up and down, and to provide a file equipped with a binding tool that is easy to operate and convenient to use. .

In order to achieve this object, the present invention provides a mounting plate that is fixed to the inner end of the back plate of the cover body, a required number of sliding pieces that have openings at least on the front side and top side and are fitted to the mounting plate so as to be slidable in the left and right direction,
The binding device is equipped at least at one end of the inner surface of the spine of the cover body and is composed of a pin body that has a finger hook and a spring-like projection and a contact portion for a spring body described below and is stored inside the sliding top so that it can slide freely in the front-to-back direction, with the finger hook protruding from the top opening and at least its front end being able to protrude or retract from the front side opening, a spring body that is stored inside the sliding top and presses the pin body forward, and a projection for engaging the spring-like projection that is provided at the location where the spring-like projection of the pin body is located when the front end of the pin body slides into the retracted state inside the sliding top. An embodiment of the binding device is described below with reference to the drawings.

At one end of the inner surface of the spine section 2 of the cover body 1, there is a guide groove 3 that is long in the horizontal direction and faces inward at its front and rear ends.
A mounting plate 4 having a portion 3' formed thereon is fixed.

Next, it has a cubic shape with a required space inside and is long in the front and back direction, and has a long opening 5 on the top surface.
The required number of sliding pieces 8 each have an opening 6, 6' on each of the front and rear sides, and have protrusions 7, 7' formed at the lower end of each of the front and rear sides. ，
7' is fitted into the guide grooves 3, 3' of the mounting plate 4, and is fitted to the mounting plate 4 so as to be slidable in the left and right direction. Inside this sliding piece 8, a long plate-shaped pin body 9 is housed so as to be slidable in the front and rear directions, and its front and rear ends protrude from the openings 6, 6' on the front and rear sides of the sliding piece 8. Or immersive. The pin body 9 has a finger hook 10 protruding from the upper opening 5 of the sliding piece 8 at the center of its upper edge, and an arcuate spring protrusion 11 at the center of its lower edge. Further, a horizontal plate 12, which is a contact portion of a spring body to be described later, is provided protruding from the side surface.

Next, a coil spring 13 is housed inside the sliding piece 8 with its front end in contact with the rear surface of the horizontal plate 12 and attached to the side surface of the pin body 9, and the pin body 9 is pressed forward by the coil spring 13. be done. Furthermore, sliding piece 8
A base plate 15 having a protrusion 14 on its upper surface is housed inside the pin body 9 below the pin body 9 . Protrusion 14 of base plate 15
When the pin body 9 is slid backward and the front end is retracted into the sliding piece 8, the spring protrusion piece 1
1 is provided at a position where it can be engaged.

The binding tool 16 is constructed as described above, and its function is as follows. First, in the normal state, coil spring 1
The pin body 9 is pressed forward by the elastic force of 3, and the front end of the pin body 9 penetrates through the front side opening 6 of the sliding piece 8 and protrudes. Therefore, the object to be filed is clamped in this state.

Next, when the pin body 9 is slid backward while pressing the finger hook 10 and compressing the coil spring 13, the rear end of the pin body 9 protrudes from the rear side opening 6' of the sliding piece 8, and the pin body The front end of the pin body 9 is recessed into the sliding piece, and the spring protrusion piece 11 of the pin body 9 is engaged with the protrusion 14 of the base plate 15. Therefore, in this state, it is possible to attach and detach the object to be filed. In order to make the pin body 9 protrude forward again, it is sufficient to pull the finger hook piece 10 forward, and the springy protrusion piece 11 of the pin body 9 is retracted upward due to its spring property, so that it engages with the protrusion 14 of the base plate 15. The engagement is released, and the elastic force of the coil spring 13 causes it to slide forward and protrude.

In the embodiment described above, the spring protrusion piece 11 of the pin body 9 is provided at the lower edge of the pin body 9, but its position can be changed to other positions such as the side surface, or Although the base plate 15 is provided with a protrusion 14 that engages with the spring protrusion piece 11 of the pin body 9, it is also possible to provide the protrusion 14 directly on the inner wall of the sliding piece 8 without using the base plate 15. Although the coil spring 13 is attached to the side surface of the pin body 9, it is also possible to provide a stepped portion at the rear end of the pin body 9 and make it abut thereon, thereby eliminating the horizontal plate 12. To briefly explain another binding tool 17 provided on the other end of the inner surface of the spine portion 2 of the cover 1, it has a support body 20 having a horizontal elongated hole 19 in the upper surface 18 and openings on the front and rear sides. , a required number of pin bodies 24 having a long piece part 21 and a folded piece part 22, and a required number of pin bodies 24 in which the folded piece part 22 is provided with protrusions 23 toward the long piece part 21 side,
The pin body 24 connects its folded piece 22 to the support body 20
is inserted into the inside of the long piece part 21 and the folded piece part 2.
2, and the projection 23 of the folded piece 22 is fitted into the elongated hole 19 of the upper surface 18 and locked, and the elongated piece 21 protrudes forward of the support body 20 and the cover body 1. This acts to hold the object to be filed.

By having the present invention constructed as described above, the pin body does not undulate up and down but slides back and forth, so the tip of the pin does not hit the user, making it extremely safe. Further, the operation is extremely simple as it only requires moving the finger hook of the pin body back and forth.

As described above, it has excellent effects in terms of safety and usability.
