Abstract

A manual binding tool in which, without transferring the fingers, tightening and cutting can be performed simply by gripping a pair of levers. The manual binding tool includes a tightening mechanism that pulls a projection tie portion that is passed through a head portion, a cutting mechanism that cuts the projection tie portion in the vicinity of the head portion, first and second levers, a tightening linkage mechanism that links the levers with the tightening mechanism in a state where the projection tie portion is pulled by gripping of the levers in a range within a predetermined angle, and a cutting linkage mechanism that links the levers with the cutting mechanism in a state where the projection tie portion is cut by gripping the levers beyond the predetermined angle. A switching mechanism alternatively allows one of the tightening or cutting linkage mechanism to operate based upon tightening force.

Claims

1. A manual binding tool, comprising:

a tightening mechanism that pulls a projection tie portion that projects through a head portion, with respect to the head portion;

a cutting mechanism that cuts the projection tie portion in a place in a vicinity of the head portion;

a first lever and second lever that are pivotally coupled to each other;

a tightening linkage mechanism that links the first lever and the second lever with the tightening mechanism in a state where the projection tie portion is pulled by relatively approaching swinging in a range within a predetermined relative angle of the both levers; and

a cutting linkage mechanism that links the first lever and the second lever with the cutting mechanism in a state where the projection tie portion is cut by relatively approaching swinging of the both levers beyond the predetermined relative angle, and

a switching mechanism which, when a pulling force of the tightening mechanism is smaller than a preset value, sets a tightening state where the tightening linkage mechanism is caused to operate, and the cutting linkage mechanism is caused not to operate, and, when the pulling force of the tightening mechanism reaches the preset value, causes the tightening linkage mechanism not to operate, and the cutting linkage mechanism to operate.

2. The manual binding tool according to claim 1, wherein the cutting mechanism includes a pushing mechanism that pushes and deforms a tie portion located in the head portion, and that causes the deformed portion to be engaged into a hole of the tie portion onto which the head portion is previously fitted.

3. The manual binding tool according to claim 2, wherein

the tool is configured in a state such that, in accordance with movement in which the first lever and the second lever are relatively approaching swung by the tightening mechanism from a waiting state where the both levers are mostly openly swung, the projection tie portion is gripped by a pulling portion and then pulled by the pulling portion, and

a return preventing mechanism is configured so as to, when the projection tie portion is not gripped by the pulling portion, block a return movement of the projection tie portion to the head portion.

4. The manual binding tool according to claim 1, wherein a tightening adjusting mechanism that can change setting of a maximum value of a pulling force caused by the tightening mechanism is disposed.

5. The manual binding tool according to claim 2, wherein a tightening adjusting mechanism that can change setting of a maximum value of a pulling force caused by the tightening mechanism is disposed.

6. The manual binding tool according to claim 3, wherein a tightening adjusting mechanism that can change setting of a maximum value of a pulling force caused by the tightening mechanism is disposed.
