Description

[Brief explanation of the drawing]

The figures show an embodiment of the ring binder of the present invention, in which Fig. 1 is a perspective view showing the whole, Fig. 2 is an exploded perspective view of main parts, Fig. 3 is an enlarged bottom view of the whole, and Fig. 4 is a perspective view showing the whole. The figure is Figure 1A
- A cross-sectional view taken along line A, Figure 5 shows the state in which the operating lever is laid down, an enlarged bottom view similar to Figure 3, and Figure 6.
The figure is a cross-sectional view similar to that shown in FIG. 4, FIG. 7 is an enlarged bottom view similar to that shown in FIG. 3 with the control lever pushed back halfway, and FIG. It is a similar sectional view.

Claims (1)

[Scope of utility model registration request] A pair of springboards 2.2 are placed inside a frame 1 formed of a thin metal plate.
' are interposed by engaging the engaging claws 3, 3' provided on the opposite side edges, and the spring plates 2, 2' are inserted using the elastic force of the frame 1.
The engaging edges 4, 4' of are caused to snap upwardly and downwardly within the frame 1 by means of operating levers 5, 5', and the plurality of pairs fixed on the surface of the springboard 2.2' and protruding above the frame 1 are In the ring binder main body 7, which is structured to open and close the halved binding rings 6, 6' by the above-mentioned snap movement, the operating lever 5°5'
is formed into an almost upside-down 7-shape, with the longer vertical portion 8 serving as the finger rest portion 9, and a pair of deep cuts on both sides of the continuous portion of the horizontal portion 10 and the shorter vertical portion 11. 12.
12' is provided and the same part is used as the neck part 13, and this neck part 1
3 into a hole 14 made by cutting out a portion near the end of the retaining edges 4, 4' of the flip plate 2.2', the operating lever 5.5' is attached to the ring binder main body 7. The shorter vertical part 11 is between the upper surface of the springboards 2, 2' and the lower surface of the frame 1, the horizontal part 10 is on the lower surface of the springboards 2, 2', and the finger rest part 9 is between the ring binder main body 7. It is attached so that it can be raised and lowered freely with each end protruding outward from both ends, and the deep cut 12.
12', move the incisal edge of the horizontal part □10 to the operating lever 5.
5' sloped edge 16 for pushing up that takes on the shape of a) when it is laid down.
．． 16', and the incisal edge on the side of the shorter vertical part 11 is made into a pressing inclined edge 17.17' which takes on an inverted V-shape when the operating lever 5.5' is raised. The left and right sides are bent inward to form push-down legs 18.18', and when the operating levers 5, 5' are lowered, the inner ends of the above-mentioned push-up inclined edges 16.16' the engaging edges 4, 4' of both springboards 2.2' upwardly, and the push-down legs 18.18' facing the outer edges 20.2 of both springboards 2.2'.
Both springboards 2.0' are pressed downward at the same time. ~2'
is made to snap upward, and when the user also stands up, the inner end portions of the push-down inclined edges 17, 17' move the engaging edges 4, 4' of both spring plates 2, 2' downward, and the shorter one A ring binder in which the top edges 21 of the vertical portions 11 simultaneously press the lower surface of the frame 1 upward, thereby snapping both the spring plates 2, 2' downward.
