Abstract

A coupling member for an electric power tool is provided. The coupling member can keep a hanging member being held, even when a holding portion of the tool for holding the hanging member breaks. A coupling member for an electric power tool is configured to hook a hanging member to an electric power tool main body and can fasten the electric power tool main body therein, when one of its parts opens or closes. Further, this coupling member can be attached to the electric power tool main body with the electric power tool main body fastened therein or removed therefrom. Further, the hanging member can be hooked to the coupling member.

First claim

What is claimed is:

1. An electric power tool comprising:
a loop handle; and
a coupling member (a) configured to be (1) attached to and detached from the loop handle and (2) moved between an open state and a closed state and (b) including one or more hook part configured to receive a hanging member, wherein:
in the closed state, ends of the coupling member are adjacent;
in the open state, the ends of the coupling member are spaced apart such that the loop handle can pass between the ends; and
when the coupling member is in the closed state and the loop handle is within the coupling member, the loop handle extends in opposite directions with respect to the coupling member.

2. The electric power tool as defined in claim 1 , wherein the coupling member moves between the open state and the closed state via one or more hinge.

3. The electric power tool as defined in claim 2 , the coupling member further comprising:
a fastening body having a fastening space to receive the loop handle; and
one or more attachment body openably/closably coupled to the fastening body via the one or more hinge so as to be attached to the loop handle while the loop handle is received in the fastening body.

4. The electric power tool as defined in claim 3 , wherein:
the one or more attachment body is a pair of attachment bodies;
the one or more hook part is a pair of hook parts;
each of the pair of hook parts has a through hole into which the hanging member can be hooked; and
each of the through holes of the pair of the hook parts is adjacent to each other when the pair of attachment bodies are attached to the loop handle.

5. The electric power tool as defined in claim 3 , wherein:
the one or more attachment body rotates along a plane between an opened position and a closed position;
the one or more attachment body has an engagement portion extending along the plane; and
the engagement portion engages a recessed groove of the loop handle when the one or more attachment body is in the closed position.

6. The electric power tool as defined in claim 5 , wherein the one or more attachment body is attached to the loop handle by a screw.

7. The electric power tool as defined in claim 2 , wherein a silencer member is fitted and inserted into each of the one or more hinge.

8. The electric power tool as defined in claim 2 , wherein:
the coupling member includes a fastening body that is coupled via the hinge such that the loop handle can be fastened therein, and
a hook part configured to allow a hanging member to be hooked is integral with the fastening body.

9. The electric power tool as defined in claim 1 , wherein the opposite directions are perpendicular to a plane of movement of the coupling member when the coupling member moves between the closed state and the open state.

10. An electric power tool comprising:
a loop handle; and
a coupling member (a) configured to be attached to and detached from the loop handle and (b) including:
a fastening body having a fastening space to receive the loop handle;
an attachment body attached to a first end of the fastening body and configured to be attached to the loop handle; and
a hinge on the fastening body and configured such that the attachment body can be moved between an open state and a closed state via the hinge, wherein:
the loop handle can pass through the coupling member when the attachment body is in the open state;
the loop handle cannot pass through the coupling member when the attachment body is in the closed state; and
when the attachment body is in the closed state and the loop handle is in the fastening space, the loop handle extends in opposite directions with respect to the coupling member.

11. The electric power tool as defined in claim 10 , wherein:
the fastening body comprises a first fastening body and a second fastening body; and
the first fastening body and the second fastening body are connected via the hinge.

12. The electric power tool as defined in claim 10 , further comprising a hook part configured to receive a hanging member.

13. The electric power tool as defined in claim 12 , wherein the hook part is integral with the fastening body.

14. The electric power tool as defined in claim 12 , wherein the hook part is attached to the attachment body.

15. The electric power tool as defined in claim 14 , wherein the hook part projects in a direction away from the fastening space when the attachment body is attached to the loop handle.

16. The electric power tool as defined in claim 10 , wherein:
the attachment body comprises an engagement portion projecting outwardly, and
the engagement portion is configured to project toward the fastening space when the attachment body is attached to the loop handle.

17. The electric power tool as defined in claim 16 , wherein the engagement portion is configured to rotate about the hinge when the fastening body moves from the closed state to the open state.

18. The electric power tool as defined in claim 16 , further comprising a hook part that is farther from the fastening space than the engagement portion when the attachment body is attached to the loop handle.

19. The electric power tool as defined in claim 10 , further comprising a fixture body rotatable about the hinge, wherein the fixture body is configured to rotate about the hinge so as to close the fastening space.

20. The electric power tool as defined in claim 10 , wherein the opposite directions are parallel to an axis of rotation of the hinge.
