Description

[Detailed description of the invention] [Industrial application field] This invention is an iron case that houses an iron, more specifically, when the case lid is closed to the case body, the case body or the case lid is elastically deformed. The present invention relates to a lock holding structure that prevents a case lid from being unlocked.

[Prior Art] For example, in Utility Application No. 61-94470, the present applicant has disclosed that when a case lid is closed with respect to a case body in which an iron is housed, the lock is locked to an engaged portion provided on the case lid. The hook maintains the closed state, and when the operation button is pressed,
We have proposed an iron case equipped with a locking member that opens the case lid using the elastic force of an elastic member.

[Problems to be solved by the invention] However, in the above-mentioned iron case, the case body and case lid are molded from synthetic resin that is easily deformed, so when an external force is applied to the iron case, the case deforms. The main body or the case lid easily elastically deforms and expands in the lateral direction. Therefore, there is a problem in that the case lid may be opened against the operator's will due to the unlocking of the engaged portion and the hook due to elastic deformation of the case body or the case lid.

[Purpose of the invention] In view of the above-mentioned conventional drawbacks, the purpose of the invention is to
It is possible to reliably maintain the closed state of the case body and case lid, and the case lid can be automatically opened by moving the operating member, and even if the side of the case body or case lid is elastically deformed and spread. To provide an iron case that securely maintains a locked state between a case body and a case lid and prevents a housed iron from flying out even if the case body and case lid are locked.

[Means for Solving the Problems] Therefore, the present invention provides a case body which has a protective body for accommodating the iron inside, is open at the front, and has a stepped portion over almost the entire edge of the opening side. a case lid that is supported so as to be openable and closable at one front end of the case body so as to cover the opening, and has an engaging portion that engages with the stepped portion on the side facing the case body; a locking plate provided on the non-support side side surface of the case lid, having a locking part and a hook part locking at one end, and having the other end swingably supported on the non-support side inner surface of the case body; A first elastic member is provided between the inner surface of the case body and the locking plate, and is provided between the inner surface of the case body and the locking plate, and biases the locking plate in a direction in which the hook portion and the locking portion are locked. a second elastic member that comes into contact with the locked part to bias the case lid in the opening direction; and a first elastic member that comes into sliding contact with a protrusion provided on the locking plate to move the locking plate. a locking member consisting of an actuating member that swings in the unlocking direction against the elastic force of the locking member; and a case lid or an end of the case body that faces either the case body or the case lid adjacent to the locking member. An ironing case is constituted by a latching portion that is latched to the edge.

[Operation of the invention] Since the invention is constructed as described above, when the case lid is closed to the case body, the engaging portion of the case lid is engaged with the stepped portion of the case body.

In the closed state, the second elastic member is elastically deformed by contact with the locked part locked to the hook part,
The elastic force urges the case lid in the opening direction. Further, in the locking plate, the locked state of the hook portion with respect to the locked portion is maintained by the elastic force of the first elastic member.

In the above-mentioned locked state, the case body and the case lid are held in an engaged state over almost the entire edge due to the engagement between the stepped part and the engaging part, and are latched near the locking member. Even if the iron case is elastically deformed by an external force, the hooking part will maintain the hooked state of both parts, deforming the iron case as a whole and maintaining the closed state. It can be done.

When the actuating member is moved in the above state,
As the locking plate slides into contact with the protrusion, the locking plate is swung against the elastic force of the first elastic member to unlock the locked portion and the hook portion.

As the lock is released, the case lid is released from the case body by the elastic force of the second elastic member.

Next, the operation of the iron case 1 constructed as described above will be explained with reference to FIGS. 5 to 8.

In FIG. 5 showing the locked state of the case body 3 and the case lid 5, and FIG. 6 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 into 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 of the leaf spring 47 comes into contact with the locking part 61 and is elastically deformed, so that the case lid 5 is held by the elastic force. It is biased in the opening direction.
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 hook portions 17 located on the upper and lower sides of the locking member 41. .

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. 7 showing the engaged state of the protruding 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 leaf spring 47 in which the spring piece 47a contacts the locked part 61, the locking of the hook part 41b with respect to the locking hole 61a is released. Then, the case lid 5 is attached to the leaf spring 4.
It is automatically released from the case body 3 due to the elastic force of 7.

[Effects of the invention] Therefore, the present invention can reliably maintain the closed state of the case body and case lid, and can automatically open the case lid by moving the actuating member. It is possible to provide an iron case that reliably maintains the locked state between the case body and the case lid and prevents the housed iron from flying out even when the side surfaces are elastically deformed and expanded. .
