## Abstract

To make it possible to simply and easily attach/detach an attaching target to/from an attached target. A coupler includes: a base to be fixed to an attached target; and an attachment body that is fixed to the attaching target and to be detachably joined to the base, in which: the base includes a joint surface to be joined to the attachment body, a magnet configured to magnetically attach the attachment body to the joint surface, and an engaging part configured to engage with the attachment body; and the attachment body includes a joint surface to be joined to the base, a magnet configured to magnetically attach the magnet of the base to the joint surface, and an engaged part configured to disengageably engage with the engaging part of the base and restrict separation from the base.

## Claims

### Claim 1

A coupler comprising:
a base to be fixed to an attached target; and
an attachment body that is fixed to an attaching target and to be detachably joined to the base, wherein:
the base includes a joint surface to be joined to the attachment body, a magnet configured to magnetically attach the attachment body to the joint surface, and an engaging part configured to engage with the attachment body; and
the attachment body includes a joint surface to be joined to the base, a magnet configured to magnetically attach the magnet of the base to the joint surface, and an engaged part configured to disengageably engage with the engaging part of the base and restrict separation from the base.

### Claim 2 (depends on 1)

The coupler according to claim 1, wherein
a back surface of the base includes a fixing member to be fixed to the attached target, and a front surface of the attachment body includes an attachment tool attached to the attaching target.

### Claim 3 (depends on 1)

The coupler according to claim 1, wherein the magnet of the base includes two magnets having different surface poles, and the magnet of the attachment body includes two magnets that are to be attracted and guided by the magnet of the base.

### Claim 4 (depends on 1)

The coupler according to claim 1, wherein
the base includes a guide member formed including left and right side guide parts configured to guide a position of the attachment body in a left-right direction at a time of magnetic attachment, and a lower guide part configured to guide a downward position.

### Claim 5 (depends on 1)

The coupler according to claim 1, wherein
the engaging part of the base and the engaged part of the attachment body are provided below the joint surface of the base and below the joint surface of the attachment body, respectively, and one is a protrusion protruding in a top-bottom direction, whereas the other includes a hole and a hole wall part that are configured to disengageably engage with the protrusion in the top-bottom direction.

### Claim 6 (depends on 1)

The coupler according to claim 1, wherein
the engaging part of the base and the engaged part of the attachment body are provided above the joint surface of the base and above the joint surface of the attachment body, respectively, and one is a hook part protruding the joint surface, whereas the other includes an opening part into or out of which the hook part is capable of being moved by joint direction relative movement, and a locking part that protrudes into the opening part and is configured to be engaged with the hook part.

### Claim 7 (depends on 6)

The coupler according to claim 6, wherein
the base is provided with a locking mechanism configured to restrict the hook part engaging with the locking part from relatively moving in a detachment direction.

### Claim 8 (depends on 7)

The coupler according to claim 7, wherein
the attachment body is formed with the hook part, and the base is formed with the opening part and the locking part, and
the locking mechanism includes: a locking hole formed in the hook part; an engaging pin that is provided to the base and by protruding into the opening part, inserted into the locking hole to restrict the hook part from relatively moving in the detachment direction; and a spring that biases the engaging pin in a protruding direction.

### Claim 9 (depends on 8)

The coupler according to claim 8, wherein
the locking mechanism includes: an operation knob slidably attached to the base; and an interlocking member configured to move back the engaging pin from the opening part by sliding of the operation knob.

### Claim 10 (depends on 7)

The coupler according to claim 7, wherein
the base is formed with the hook part, and the attachment body is formed with the opening part and the locking part, and
the locking mechanism includes: an operation body that is provided in the base, faces to the hook part, sandwiching the locking part, and thereby restricts the hook part from relatively moving in the detachment direction; a spring that biases the operation body to a position facing to the hook part; and an operation knob configured to move back the operation body from the position facing to the hook part while resisting the spring.

### Claim 11 (depends on 2)

The coupler according to claim 2, wherein
the attachment tool includes: a male screw part that is rotationally movably provided to the attachment body and capable of being screwed to the attaching target, or a movable claw that is provided on the front surface of the attachment body and capable of sandwiching the attaching target.
