合を解消しようとしたが、結果は上記と同じであった。In the above-mentioned conventional staple 1, since the staple legs 3 and 3 are formed straight,
As shown in FIG. 9, when the electric tacker is driven from above the seat 6 in the direction of the arrow F against the wood 5 or the like, even if the staple leg portion 3 enters the wood 5, in principle, it only comes straight. Is. In practice, as shown in the drawing, one of the left and right leg feet 3 often bends inward, and the other leg foot 3 often goes straight. As a result, the resistance to pulling out decreases, and the force for holding the sheet 6 and the like becomes low, and in order to cope with this, it is necessary to narrow the driving interval of the staple 1. In the process of completing the present invention, the present inventor tried to eliminate the above inconvenience by bending the staple leg portions 3 and 3 of the staple 1 inward slightly more than a right angle with respect to the head portion 2. Was the same as above.

いる。As shown in FIG. 1 (b), each staple 1
0 has a rectangular cross section, has a head 11 that is pressed by an electric tucker, and has a pair of left and right symmetrical leg feet 12 that are inserted into the member to be driven, and has a U shape. I am doing it. The head 11 has a linear shape. The pair of staple legs 12 are connected to both ends of the head 11 via right-angled bent portions and are parallel to each other. The tip 15 of each staple leg 12 is sharp. Each of the staple legs 12 is bent inward (that is, in the direction in which the pair of staple legs 12 approach each other) at a position closer to the front end 15 by a predetermined dimension S1. Therefore, the tip 15 of the staple leg portion 12 projects inward from the inner side surface of the staple leg portion 12 by a dimension S2. In this manner, each of the staple legs 12 has a base portion 13 linearly extending at a right angle from the end of the head portion 11, and a tip portion 14 extending obliquely inward from the tip of the base portion 13 in a substantially linear manner. And have.

に応じて適宜決定すればよい。The dimension S1 from the tip 15 to the bending position is set to 10% to 30% of the total length H of the staple leg portion 12. For example, the total width L of the head 11 is 12.5 m
m, the total length H of the staple leg portion 12 is 10 mm, and the thickness T of the staple leg portion 12 is 0.2 to 0.4 mm, the dimension S1 is set to 2 mm. The inclination angle Θ of the inner surface of the tip portion 14 with respect to the inner surface of the base portion 13 is
It is set in the range of 2 to 20 degrees. For example, in the case of the staple having the above size, the protrusion size S2 of the tip 15 is the staple leg portion 1.
The inclination angle Θ is set so as to be substantially equal to the wall thickness T of 2. If the inclination angle Θ is less than 2 degrees, it is not possible to ensure that the staple leg portion 12 bends and advances when the staple leg portion 12 is stabbed, which will be described later. Further, if the angle exceeds 20 degrees, the staple leg portion 12 bends when the tip 15 hits the wood 5, and cannot penetrate into the wood 5. This inclination angle Θ may be appropriately determined according to the hardness of the driving target portion and the hardness of the staple 10 itself.

とができる。When the staple stack A is mounted on an electric cutter and the staple 10 is driven into the wood (the target portion to be driven) 5 from above the sheet 6 as shown in FIG. 12 is pierced from the tip 15 into the wood 5, but at that time, since the tip 14 of the staple leg 12 is inclined inward, in other words, the base portion which is a driving force transmission path. Since the tip 15 is biased inwardly from the tip 13, the tip 14 receives a stab resistance having a vector component in a direction orthogonal to the base 13 from the wood 5, and as a result, the needle foot 12 is inwardly moved. It is possible to enter the wood 5 while curving in the direction. In this way, both needle feet 12 are surely bent inward under substantially the same conditions and are stabbed inward, so that both of the curved needle feet 12 hold the wood 5 and the resistance against pulling out. Power increases. Therefore, the holding force when the sheet 6 is fixed is increased, and the holding force of each staple 10 is increased, so that the driving interval of the staples 10 can be widened, and the number of staples 10 and the number of times of driving can be reduced. be able to.

ープル集積体を製造することができる。As described above, according to the first aspect of the invention, since both of the staple legs are curved inward in the member to be driven at the time of driving, the resistance force against pulling out is increased. The holding force when fixing a sheet or the like increases. Therefore, by increasing the holding force per staple, the staple driving interval can be widened, and the number of staples and the number of times of driving can be reduced. According to the second aspect of the invention, since the inclined bent portions on both sides in the width direction of the plate-like body are formed first, and then the right-angled bent portions are formed inside thereof, the staple stack is manufactured relatively easily. can do. According to the invention of claim 3, all the bent portions can be formed by a single press working, and the staple stack can be easily manufactured.
