[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stapler clinch table having a receiving surface for receiving a material to be sewn and a clincher for bending a leg of a staple, and a protrusion at a front portion or a rear portion of the clincher portion.

[0002]

2. Description of the Related Art In general, a stapler clinch table has a receiving surface for receiving a material to be sewn and a clincher portion, and staples struck by a driver penetrate the material to be sewn placed on the receiving surface. Later, it is bent at the clincher and spelled.

Since the receiving surface of the conventional clinch table is formed in a flat shape as shown in FIG. 4, when the sewn materials 10 overlapping each other are placed on the receiving surface 11, the receiving surface 11 The spelling material 10 and the overlapped spelling materials are parallel to each other. Accordingly, in this state, the staple a
When the staple driving load is applied to the sewn material 10 when the staple is driven, the upper sewn material presses the lower sewn material toward the receiving surface side, and the sewn materials adhere to each other to form an integral lump. Becomes Since the staple a penetrates the massive portion, it receives a very high penetration resistance. For this reason, it is necessary to apply a high load to the driver in order for the staple a to penetrate the sewn material 10.

[0004]

The object of the present invention is to solve the above-mentioned drawbacks and to reduce the penetration resistance of the staple by forming a minute gap between the overlapping staples in the process of the staple penetrating the staple. It is an object of the present invention to provide a clinch table that allows a staple to penetrate a material to be sewn with a small load.

[0005]

In order to achieve the above object, a clinch table in a stapler according to the present invention has a receiving surface for receiving a material to be sewn, and is punched out from a driver on the receiving surface and the material to be sewn on the clinching table. In the clinch table in which the clincher portion for bending the leg portion of the staple penetrating is formed, a protruding portion projecting upward is formed near the clincher portion of the clinch table, and the material to be sewn placed on the receiving surface is formed. The lower surface is floated from the clincher by the protrusion.

[0006]

According to the above construction, the material to be sewn is placed on the receiving surface, and the staple is driven into the material to be sewn by the driver. However, since the sewn material rides on the protrusion formed near the clincher portion, a minute gap is formed between the overlapped sewn materials in the process of the staple legs penetrating the sewn material. .
Therefore, the staple legs penetrate the material to be sewn one by one, so that the penetration resistance of the staple is dispersed, and the peak value of the penetration resistance can be greatly reduced.
Therefore, the staple can surely penetrate the staple with a smaller load.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral A denotes an electric stapler main body. The electric stapler main body is provided with a driver 1 driven by an electric motor, a magazine 2 for supplying a staple a below the driver 1, and a clinch table 4 for receiving a material 3 to be sewn.

As shown in FIG. 2, the clinch table 4 has a receiving surface 5 for receiving the material 3 to be sewn, and a leg portion of a staple a which is punched from the driver 1 on the receiving surface 5 and penetrates the material 3 to be sewn. A clincher portion 6 for bending a1 is formed, and a protruding portion 7 protruding upward is formed near the clincher portion 6 of the clinch table 4.

The front surface 5a of the receiving surface 5 is inclined downward so that the material 3 can be easily inserted and placed between the magazine 2 and the magazine 2. The clincher portion 6 is formed in a groove shape in the figure, but may be a movable clincher that operates to bend the leg portion a1 of the staple a after the staple a has penetrated.

The protruding portion 7 is formed in a chevron near the front portion of the clincher portion 6, but as described later, the clincher portion 6 side has a receiving surface 5 in order to effectively bend the material 3 to be sewn.
It is preferable to be formed so as to be perpendicular to the surface.

Next, when binding the material 3 to be sewn, the material 3 is inserted between the clinch table 4 and the magazine 2 and placed on the receiving surface 5, and then the electric stapler is operated to activate the driver. 1 is driven. The driver 1 drives the staple a toward the material 3 to be sewn. Leg a1 of staple a
Penetrates the material to be sewn 3.

When the leg portion a1 of the staple a penetrates the material 3 to be sewn, the material 3 placed on the receiving surface 5 is placed on the protrusion 7 at the front of the clincher 6. First, as shown in FIG. 3A, the staple leg a1 comes into contact with the material 3 while the material 3 is floating from the receiving surface 5 of the clinch table 4 as shown in FIG.
Further, a driving load is applied to the leg portion a1, and the material to be sewn 3a starts to bend. Then, as shown in FIG. 2B, when the leg portion a1 finishes penetrating one sheet of the sewn material 3, the remaining sewn materials 3b and 3c receive the driving load, and the amount of bending further increases. The second sheet 3b and the second sheet 3b
, A minute gap S1 is formed. Further, when the driving load reaches the penetrating load, it penetrates the second sewn material 3b (see FIG. 3 (c)). When the penetration is completed, a small gap S2 is formed between the second material 3b and the third material 3c, and when the driving load reaches the penetration load, the third material S is formed. 3c, and the penetration ends.
The same applies to a case where there are four or more sheets.

As described above, since the leg portions a1 of the staple a penetrate one after another after the minute gap is formed between the sewn materials 3, the penetration resistance is dispersed as a whole, and the peak value of the penetration resistance is large. Can be lowered. Therefore, the staple a can surely penetrate the staple a with a smaller load.

The protruding portion 7 is not necessarily limited to the example arranged near the front portion of the clincher portion 6. It may be near the rear.
