Abstract

A rebar binding machine comprises a curl guide that causes a wire to curl, a torsion part including a torsion shaft for twisting the curled wire, and a pair of grips that can be grasped by an operator. The grips are provided to the two axial sides of the torsion shaft as viewed from the operator side when the operator grasps the grips to perform an operation, and it is possible to change the height of the grips in the axial direction of the torsion shaft.

First claim

The invention claimed is:

1. A binding machine comprising:
a first body part;
a second body part including a curl guide and a twisting unit, the curl guide having an opening in which a binding object can be inserted and being configured to curl a wire around the binding object inserted in the opening, and the twisting unit including a twisting shaft for twisting the curled wire; and
a connecting part connecting the first body part and the second body part,
wherein the first body part includes grips pairing up with each other and being able to be grasped by an operator,
wherein the grips are provided on respective both sides of an axis line of the twisting shaft, as seen from an operator-side when the operator performs an operation with grasping the grips, and positions of the grips can be changed in an axis line direction of the twisting shaft, and
wherein the grips are provided to be rotatable with respect to the first body part, and the positions of the grips can be changed in the axis line direction of the twisting shaft by rotation of the grips.

2. The binding machine according to claim 1 , further comprising handle parts including the respective grips,
wherein each of the handle parts includes a grip connecting portion connecting one of the grips and the first body part, and
wherein each of the grips has a ring shape.

3. The binding machine according to claim 2 , wherein the grip connecting portion includes a shaft that is inserted in a hole provided to the first body part, and
wherein each of the handle parts is configured to be rotatable about the shaft as a support point.

4. The binding machine according to claim 2 , further comprising a biaxial hinge connecting the grip connecting portion and the first body part,
wherein each of the handle parts is configured to be rotatable about the biaxial hinge as a support point in a first direction, which is a plane direction of the first body part, and in a second direction orthogonal to the first direction.

5. The binding machine according to claim 1 , wherein each of the grips includes a first grip portion and a second grip portion,
wherein the first grip portion and the second grip portion are connected such that axis lines of the first grip portion and the second grip portion are non-parallel, and
wherein each of the grips is configured so as to be movable between a first position at which the first grip portion is orthogonal to the axis line of the twisting shaft and a second position at which the second grip portion is orthogonal to the axis line of the twisting shaft, as each of the grips rotates with respect to the first body part.

6. The binding machine according to claim 5 , wherein each of the grips is provided to the first body part such that a height of the first grip portion at the first position is higher than a height of the second grip portion at the second position.

7. The binding machine according to claim 1 , further comprising handle parts including the respective grips,
wherein each of the handle parts includes a grip connecting portion connecting one of the grips and the first body part, and forms a ring-shaped body together with the grip connecting portion.

8. A binding machine comprising:
a first body part;
a second body part including a curl guide and a twisting unit, the curl guide having an opening in which a binding object can be inserted and being configured to curl a wire around the binding object inserted in the opening, and the twisting unit including a twisting shaft for twisting the curled wire; and
a connecting part connecting the first body part and the second body part,
wherein the first body part includes grips pairing up with each other and being able to be grasped by an operator,
wherein the grips are provided on respective both sides of an axis line of the twisting shaft, as seen from an operator-side when the operator performs an operation with grasping the grips, and positions of the grips can be changed in an axis line direction of the twisting shaft, and
wherein the first body part has a plurality of groove portions to which the grips can be attached, in the axis line direction of the twisting shaft.

9. The binding machine according to claim 8 , wherein the grips is arranged such that axis lines of the grips are orthogonal to the axis line of the twisting shaft.

10. The binding machine according to claim 8 , wherein the plurality of groove portions include a groove portion extending in the axis line direction of the twisting shaft, one of the grips being able to be attached to the groove portion.

11. A binding machine comprising:
a first body part;
a second body part including a curl guide and a twisting unit, the curl guide having an opening in which a binding object can be inserted and being configured to curl a wire around the binding object inserted in the opening, and the twisting unit including a twisting shaft for twisting the curled wire; and
a connecting part connecting the first body part and the second body part,
wherein the connecting part includes grips pairing up with each other and being able to be grasped by an operator, and
wherein the grips are provided on respective both sides of an axis line of the connecting part, as seen from an operator-side when the operator performs an operation with grasping the grips, and positions of the grips can be changed in an axis line direction of the twisting shaft.

12. The binding machine according to claim 11 , wherein the grips is arranged such that axis lines of the grips are orthogonal to an axis line of the twisting shaft.

13. The binding machine according to claim 11 , wherein the connecting part further includes a slide groove for axially sliding the grips in an axis direction of the connecting part.

14. A binding machine comprising:
a first body part;
a second body part including a curl guide and a twisting unit, the curl guide having an opening in which a binding object can be inserted and being configured to curl a wire around the binding object inserted in the opening, and the twisting unit including a twisting shaft for twisting the curled wire; and
a connecting part connecting the first body part and the second body part,
wherein the first body part includes grips pairing up with each other and being able to be grasped by an operator,
wherein the grips are provided on respective both sides of an axis line of the twisting shaft, as seen from an operator-side when the operator performs an operation with grasping the grips, and positions of the grips can be changed in an axis line direction of the twisting shaft, and
wherein the grips are configured such that heights of one of the grips and an another of the grips in the axis line direction of the twisting shaft can be individually changed when the operator performs an operation with grasping the grips.
