Abstract

A binding machine includes a curl guide configured to guide a wire in a loop shape around a binding target and a twisting part configured to bind the binding target by twisting the wire guided in the loop shape around the binding target. The curl guide has a tapered protrusion at a tip end-side.

First claim

1 . A binding machine comprising:
a curl guide configured to guide a wire in a loop shape around a binding target, and a twisting part configured to bind the binding target by twisting the wire guided in the loop shape around the binding target, wherein the curl guide has a tapered protrusion at a tip end-side.

2 . The binding machine according to claim 1 , wherein the protrusion has a guide part provided on an outer periphery-side of the protrusion and arranged substantially perpendicularly to an extension line of a shaft of the twisting part.

3 . The binding machine according to claim 1 , wherein the protrusion is detachable to the curl guide or a binding machine main body configured to support the curl guide.

4 . The binding machine according to claim 2 , wherein the guide part is configured as a planar surface.

5 . The binding machine according to claim 2 , wherein the guide part is configured as a planar surface having a convex portion or a concave portion.

6 . The binding machine according to claim 2 , wherein the guide part is configured as a curved surface approximate to a planar surface.

7 . The binding machine according to claim 2 , wherein
the protrusion has a pointed tip end, and the protrusion is provided at an inner periphery-side, which is opposite to the guide part, with an inclined guide part configured to guide the binding target from a tip end-side toward a base end-side.

8 . The binding machine according to claim 1 , wherein the protrusion is mounted to be displaceable relative to the curl guide.

9 . The binding machine according to claim 1 , further comprising a protection part configured to be continuous to the protrusion and to cover at least a part of an outer surface of the curl guide from an outside.

10 . The binding machine according to claim 9 , wherein the protection part has an outer periphery protection surface configured to cover an outer periphery-side surface of the outer surface of the curl guide.

11 . The binding machine according to claim 9 , wherein the protection part has a side surface protection surface configured to cover at least one side surface of the outer surface of the curl guide.

12 . The binding machine according to claim 9 , wherein the protection part has a U-shaped section part having:
an outer periphery protection surface configured to cover an outer periphery-side surface of the outer surface of the curl guide; and a pair of side surface protection surfaces configured to cover both side surfaces of the outer surface of the curl guide.

13 . The binding machine according to claim 1 , wherein
the protrusion has an outer periphery constituting surface configuring an outer periphery-side surface of the protrusion, and the outer periphery constituting surface has a width-narrowed part of which a width gradually decreases toward a tip end-side.

14 . The binding machine according to claim 13 , wherein
the protrusion has a pair of side constituting surfaces configuring side surfaces of the protrusion, and the width-narrowed part has a shape tapered toward one side constituting surface.

15 . The binding machine according to claim 1 , wherein
the protrusion has a side constituting surface configuring a side surface of the protrusion, and the side constituting surface has a shape tapered toward a tip end-side.

16 . The binding machine according to one of claims 1 , wherein the protrusion has a mark indicative of a position, through which the wire is to pass, on an outer periphery-side or inner periphery-side surface.

17 . The binding machine according to claim 1 , wherein the protrusion is provided on at least one side surface of an outer surface of the curl guide.

18 . An auxiliary member for binding machine mounted to a curl guide configured to guide a wire in a loop shape around a binding target or to a binding machine main body configured to support the curl guide, wherein
the auxiliary member for binding machine has a tapered protrusion that is positioned at a tip end-side of the curl guide when it is mounted to the curl guide or the binding machine main body, and the auxiliary member for binding machine is detachably provided to the curl guide or the binding machine main body.

19 . The auxiliary member for binding machine according to claim 18 , wherein the protrusion has a guide part at an outer periphery-side, which is arranged substantially perpendicularly to an extension line of a shaft of a twisting part configured to bind the binding target by twisting the wire guided in the loop shape around the binding target.
