In FIG. 6 showing the locked state of the case body 3 and the case lid 5, and FIG. 7 showing the cross section taken along the line B-B in FIG. When the case lid 5 is closed around the hinge 7, the hook portion 41b of the locking member 41 is locked in the locking hole 61a of the locking portion 61 that has entered along the inner surface of the case body 3. Ru. At this time, since the locking member 41 is urged to the locking position by the elastic force of the compression spring 43, the locking hole 61a
The locked state of the hook portion 41b and the hook portion 41b is maintained. Further, when the locking part 61 enters into the case body 3, the spring piece 47a is elastically deformed by contact with the locking part 61, so that its elastic force causes the case lid 5 to be pushed in the opening direction. It is strong. Further, when the case lid 5 is closed with respect to the case body 3, the rib portion 59 inserted into the stepped portion 13 of the case body 3 is latched to the latching portions 17 located on the upper and lower sides of the locking member 41. Ru.

In the above state, the cam surface 51a at the other end of the actuating belt 51 moves upward due to its elastic force, and is maintained in a non-contact state with the cam portion 41a, and the release button 35 is pushed upward.

In FIG. 8, which shows the engagement state between the projecting piece 31b and the locking piece 57, when the handle 31 is rotated upward to stand up when carrying the iron case 1 containing the iron, the shaft As the portion 31a rotates, the protruding piece 31b engages the hooking piece 57 of the actuating belt 51.
The movement of the actuating belt 51 in the downward direction is restricted. As a result, even if the release button 35 is pressed down by mistake when carrying the iron case 1, the movement of the actuating belt 51 is restricted, thereby avoiding contact between the cam surface 51a and the cam part 41a. This prevents the case lid 5 from being opened from the case body 3.

Further, when the case body 3 or the case lid 5 is deformed so that its side surfaces are expanded due to an external force acting on the case body 3 or the case lid 5 in the locked state, the latching portion 17 and the rib portion 59 is hooked, the case body 3 and the case lid 5 are elastically deformed as one, and the hook portion 41b and the locking hole 61
The locked state with a is maintained. This prevents the case lid 5 from being opened due to external force acting on the case body 3 or the case lid 5.

Next, to explain the opening action between the case body 3 and the case lid 5, in FIG. It is rotated downward to be supported by the stepped portion 29. As a result, the state in which the projection piece 31b is engaged with the engagement piece 57 is released.

When the release button 35 is pressed in the above state,
The other end of the actuating belt 51 moves downward along the inner surface of the case body 3, and its cam surface 51a comes into sliding contact with the cam portion 41a. As a result, the locking member 41 rotates from the locking position to the unlocking position against the elastic force of the compression spring 43, and the locking of the hook portion 41b with respect to the locking hole 61a is released. At this time, since the case lid 5 is biased in the opening direction by the elastic force of the spring piece 47a that comes into contact with the locked part 61, when the locking of the hook part 41b with respect to the locking hole 61a is released, the case The lid 5 is automatically opened from the case body 3 by the elastic force of the spring piece 47a.

In this way, in this embodiment, when carrying the iron case 1 containing the iron, the handle 31
When the operating belt 51 is rotated upward so as to stand up, the projecting piece 31b is engaged with the latching piece 57, and the actuating belt 51
The movement of people is regulated. This prevents the cam surface 51a from coming into contact with the cam portion 41a when the release button 35 is pressed down by mistake while carrying the iron case 1, and allows the hook portion 41 to engage with the locking hole 61a.
This prevents the locked state of b from being released.

[Effects of the invention] Therefore, the present invention can provide an ironing case that can simplify the structure and reduce manufacturing costs by making it impossible to release the locking device in conjunction with the operation of the handle. It is possible.
