Description

[Detailed Description of the Invention] The present invention relates to an improvement of a binding device for binding various documents, paper sheets such as newspapers and magazines.

Conventional binding tools of this type have a presser plate fixed to a protrusion that protrudes perpendicularly above the base material and has a leaf spring springing in an arcuate shape on the underside thereof, and is movably attached in the vertical direction. Paper sheets inserted between the material and the leaf spring fixed to the presser plate are clamped by pressing down on the center of the presser plate, and the presser plate is attached to the protrusion by pressing the opposite end of the presser plate. It was configured to release the pinch by pressing.

However, with the above-mentioned conventional device, in order to increase the clamping force of the paper sheets, the elastic force of the leaf spring must be increased, and when the elastic force of the leaf spring is increased, it becomes difficult to clamp the paper sheets. However, it is necessary to significantly increase the pressing force of the presser plate, and furthermore, an extremely large force is required to release the clamped state.

In addition, the conventional method has a problem in that the range of the amount of binding is limited.

In view of this, the present invention eliminates the conventional holding structure using leaf spring force, and by pressing down the holding tool when binding paper sheets, it is possible to temporarily hold the paper sheets with a certain amount of force. The object of this invention is to provide a binding tool that can securely bind by strongly pressing the presser tool, and can release the binding with a single touch when released.

The present invention will be explained below with reference to embodiments shown in the drawings.

The binding tool according to the present invention is shown in Fig. 1 in a flat state when it is in a binding state.
As shown in an exploded perspective view in FIG. 2 and in cross-section in FIGS. a guide member 5 inserted through a vertical piece 4 that stands perpendicular to , a spring piece 6 interposed between the holding tool 2 and the guide member 5, and a cam shaft for mooring the guide member 5. 7, this cam shaft release lever 8, and the holding tool 2.
It consists of an operating rod 9 that clamps the.

The holding tool 2 is formed by pressing a metal plate, and has a longitudinally long recess 10 formed on the upper surface of the central part in the longitudinal direction, and a through hole 11 between the recess 10 and the end. .11 is drilled.

The guide member 5 is cut into a fitting part 12 having a downward U-shape that fits over the holding tool 2, and a part protruding from one side of the fitting part 12. a slit-like elongated hole 13 through which the vertical piece 4 is inserted; an inclined wall 14, a bearing part 16.16 into which the shaft parts 15.15 at both ends of the release lever 8 described above are fitted and rotatably supports the shaft part 16.16, and a bearing part 16.16 which is located on the upper surface of the fitting part 12 and which can be operated as described above. A bearing portion 18 for pivotally supporting the base of the rod 9 by a pin 17, and a cut hole 20° 20 for engaging and coupling the leg piece 19° 19 of the spring piece 6 are formed, The headed pins 22.22 inserted into the through holes 21.21 bored at both ends of the fitting part 12 are inserted into the through holes 1 of the holding tool 2.
1. Insert into 11 and prevent it from coming out with some play in the vertical direction,
The guide member 5 and the presser tool 2 are integrally coupled.

The spring piece 6 is fitted into the fitting part 12 of the guide member 5, and is a shaft holding piece 23, 23 which is protruded with spring properties so as to press down the shaft 7 downward.
and a push-up piece 24 cut and raised with spring properties so as to come into contact with the inner surface of the base of the operating rod 9 and give it restorability. A bent piece 25 that hits the end of the piece to prevent it from being removed.
25, and a pin 17 for pivotally supporting the operating rod 9 at a portion opposite to the outer end of the bearing portion 18 for the operating rod 9.
A bent piece 26 is formed on the outer end of the holder to prevent it from being pulled out.

The aforementioned release lever 8 consists of a rod portion 27.27 bent at right angles from the shaft portion 15.15, and an operating portion 28 that connects this rod portion 27.27, and the rod portion 27.27 is connected to the shaft 7. It is placed in contact with the lower part of the

The operating rod 9 has a bearing portion 18 of the guide member 5 at its lower end.
a through hole 29 through which a pin 17 for pivotally supporting is inserted, and a pressing portion 31 (in the embodiment When the holding tool 2 is pushed down in the direction of the arrow in FIG. A wedge-shaped trench is formed between the inclined wall 14 and the vertical piece 4.

Next, the operation of the above embodiment will be explained.

1. Place the paper sheets 1 to be bound on the substrate 3 against the vertical piece 4, then insert the elongated hole 13 of the guide member 5 into the vertical piece 4, and press the holding tool 2 onto the top surface of the paper sheets 1. Press against.

In this case, when the guide member 5 is pressed downward by hand and then released, the holding tool 2 is pushed back by the elasticity of the paper sheet 1, but at this time, the shaft 7 touches the side surface of the vertical piece 4 and the inclined wall 14. Since the paper sheet 1 is wedged in between, it does not return more than a certain amount, and therefore the paper sheet 1 is held down by the holding tool 2.

Next, when the operating rod 9 is tilted in the direction of the arrow, the pressing part 31 at the lower end presses the concave part 10 of the presser tool 2, so the presser tool 2 is pushed down and pressed against the paper sheet 1, and at the same time is guided by the reaction force. When the member 5 is pulled up, the shaft 7 held down by the holding pieces 23, 23 of the spring piece 6 is wedged between the side surface of the vertical piece 4 and the inclined wall 14, and the guide member 5 rises further. This prevents only the presser tool 2 from coming into pressure contact with the paper sheets 1 to strongly maintain the bound state.

(Third figure shown) Next, to release the binding state, hold the operating part 28 of the release lever 8 and lift it upward as shown in the fourth figure.The shaft 7 is pushed up by the rod part 27.27, so the shaft 7 moves above the inclined wall 14, and the state in which the vertical piece 4 and the inclined wall 14 are restrained by the wedge action by the shaft 7 is released, so the guide member 5 becomes free, and at the same time, the pushing force of the spring piece 6 is released. The raised piece 24 is the operating rod 9
Since the presser tool 2 is pushed back to the upright position, the presser tool 2 is no longer suppressed by the suppressor 31, and thereby the paper sheet 1 is released from the press and can be freely removed.

In this way, with the present invention, paper sheets are held in that state by placing them under the holding tool and pushing down the guide member, so even if the paper sheets are touched during binding, there will be no movement. It is possible to maintain the temporarily held state without having to do anything, and to facilitate the binding operation.

In addition, by tilting the operating rod after the above-mentioned temporary press, the presser tool is further pushed down and the wedge action by the shaft is powerfully performed, so the binding force of the paper sheets is extremely large and the sheets do not fall off due to disorder. At the same time, since the tightening operation is performed by the lever action of the operating rod, only a light force is required.
What's more, when you want to remove paper sheets, you can do it instantly with a one-touch operation by simply pulling up the release lever.
It's easy.

Furthermore, since the guide member and the vertical piece fit together and slide against each other to abut and clamp the paper sheet, it is possible to cope with the amount of paper sheets to be bound by appropriately selecting the height of the vertical piece.
Further, regardless of the amount of binding, binding can be performed using the same operation and the same operating force.

Note that the present invention is not limited to the illustrated embodiment,
Any design changes may be made without departing from the technical idea of the present invention.
