Abstract
A vertical member having a sliding member and the like is installed on the upper face of a base member which covers a cutting blade in a condition in which the cutting blade can slide in a horizontal plane. An operational lever is provided to extend from the vertical member and a rotational member, having a fixed sandwiching member and a rotational sandwiching member, is installed on the vertical member perpendicular thereto and in a condition in which it can be freely rotated. The band part is fastened by rotating the rotational member in a condition in which the band part of a band is sandwiched by the fixed sandwiching member and the rotational sandwiching member, and the cutting blade is moved by downward movement of the sliding member to cut and remove the band part.
Claims12
A band tightening and cutting device for fastening and cutting a band that bundles a group of electric wires forming a wire harness, said device comprising:
- a base member having a band-retaining portion;
- a band pulling mechanism provided on said base member, said band pulling mechanism including a substantially L-shaped member having a vertical member and a horizontal member provided on an upper face of said base member, a rotational member mounted on said vertical member in a freely rotatable manner, and a band holding member provided on said rotational member, said band pulling mechanism rotates said holding member relative to said substantially L-shaped member and to said base member and pulls a band portion to tighten the band;
- and
- a cutting blade provided on said base member, said cutting blade being movable toward said band retaining portion in response to movement of said band pulling mechanism;
- wherein a band base portion of the band is retained by said band-retaining portion with the band portion bundled around the electric wires when the band is held by said holding member.
A method for fastening and cutting a band that bundles a group of electric wires forming a wire harness, said method comprising:
- providing a band tightening and cuffing device;
- providing a band having a band portion and a band base portion;
- inserting said band base portion in a band retaining portion of said band tightening and cutting device;
- encircling a group of wires with said band and inserting an end of said band portion into said band base portion;
- holding said band portion with a holding member of said band tightening and cutting device, said band tightening and cutting device including a band pulling mechanism including a substantially L-shaped member having a vertical member and a horizontal member provided on an upper face of a base member, a rotational member mounted on said vertical member in a freely rotatable manner, said holding member provided on said rotational member;
- and
- rotating said holding member and said band portion held thereby relative to said substantially L-shaped member and to said base member so that said band portion is pulled away from said band base portion and said band is tightened around said wires.
