Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an iron storage case capable of storing an uncooled iron, and more specifically to a locking mechanism between the case body and the case lid.

[Prior Art] In the conventional iron storage case shown in Japanese Utility Model Application No. 60-15300, a case lid is supported so as to be openable and closable via a hinge, and the side end of the case body opposite to the hinge is attached to the case lid. A locking member is integrally molded with an engaged part, and a hook that engages with the engaged part is formed at one end of the edge of the case lid corresponding to the engaged part, and the locking member is an elastic member. It is swingably supported in a state where it is biased in the locking direction by. When the case lid is closed with respect to the case body, the locking member is swung in the unlocking direction against the elastic force of the elastic member as the hook comes into contact with the engaged portion. , the hook is engaged with the engaged portion by the elastic force of the elastic member. This maintains the case body and case lid in a closed state. In addition, after the locking member is swung in the unlocking direction against the elastic force of the elastic member to disengage the hook from the engaged portion, the case lid is rotated in this state. As a result, the case lid is opened from the case body.

[Problems to be solved by the invention] However, the locking mechanism in the conventional iron storage case described above requires one hand to support the case body and the other hand to engage the engaged part and the hook. The case lid had to be opened after the lock was released, and the case lid could not be opened with one hand. Therefore, the operability was poor.

[Purpose of the invention] In view of the above-mentioned conventional drawbacks, the purpose of the invention is to
To provide an iron storage case whose case lid can be opened with one hand and whose operability can be improved.

[Means for Solving the Problems] Therefore, the present invention includes a hinge that supports the case body and the case lid so that they can be opened and closed, an engaged portion provided on the opposite end edge of the case lid, and An operating means rotatably supported by a case body facing the engaging part, and a lock pivotably supported by the case body corresponding to the operating means and having a hook facing the engaged part. a member, an elastic member that urges the locking member in the locking direction, and an elastic member that rotates integrally with the operating means and abuts a part of the locking member to force the locking member toward the elastic member. an actuating means for swinging in the unlocking direction against elastic force; and an actuating means that is elastically deformed by contact with the engaged portion when the case lid is closed with respect to the main body case; The iron storage case includes a spring means for biasing the case lid in the opening direction.

[Operation of the invention] Since the present invention is constructed as described above, when the operating means is rotated in a desired direction, the locking member swings in the unlocking direction against the elastic force of the elastic member. The engagement of the hook with the engaged portion is released.
At this time, since the case lid is urged in the opening direction by the spring means in the locked state, when the engagement between the engaged part and the hook is released, the case lid is pushed by the elastic force of the spring means. It can be opened automatically. This allows the case lid to be opened with one hand, improving operability.

[Example] An example of the present invention will be described below with reference to the drawings.

Fig. 1 is a perspective view schematically showing an iron storage case according to the present invention, and Fig. 2 is a schematic exploded perspective view of a locking mechanism. The case body 3 and the case lid 5 are supported by a hinge part 7 so as to be openable and closable. A recess 3b is formed on the upper surface of the case body 3 on both sides and at the rear thereof. A support hole (not shown) is formed in the side wall of the recess 3b located on both sides, and the support hole has a handle 11 whose front surface is substantially shaped.
is rotatably supported.

The case body 3 has a bottom wall 3a that can stand on its own, and a metal ironing stand 9 is fixed to the bottom wall 3a. Furthermore, a heat shield 14 made of heat-resistant resin is attached inside the case 3. A protrusion 3c is formed on the edge of the side wall of the case body 3 opposite to the hinge portion 7, and a through hole 3d is formed in the protrusion 3c. A metal plate spring 13 is fixed in the protrusion 3c and has a curved end so as to come into contact with an engaged portion 5a, which will be described later. An operation dial 15 constituting an operation means is rotatably supported in the through hole 3d. A portion of the shaft portion 15a of the operation dial 15 is formed to have a rectangular cross section, and a cam body 17 constituting a cam means is fixed to the shaft portion 15a having an irregular cross section so as to be prevented from rotating.
An upwardly inclined cam surface 17a is integrally formed at the end of the cam body 17. In addition, the shaft portion 1
A locking member 19 is supported on 5a so as to be swingable between a locking direction toward the outside of the case body 3 and an opposite locking direction. A hook 19a projecting outward from the case body 3 is integrally molded at the tip of the locking member 19. Further, a cam protrusion 19b is integrally formed on the outer surface of the locking member 19 (the surface facing the inner surface of the case body 3) in accordance with the cam surface 17a. A stopper 20 is screwed to the shaft portion 15a into which the locking member 19 is inserted, and one end of the shaft portion 15 corresponding to the space between the locking member 19 and the stopper 20 is connected to the hole 19c of the locking member 19. A compression spring 21 is attached, the other end of which is hooked to the hole 20a of the stopper 20. By its elastic force, the compression spring 21 swings and urges the locking member 19 in the locking direction, and also urges the operation dial 15 to rotate clockwise.

An engaged portion 5a is integrally formed on the edge of the case lid 5 side opposite to the hinge portion 7 so as to be able to protrude into the protrusion 3c, and a locking hole 5b is formed in the engaged portion 5a so that the hook 19a can be inserted into the engaged portion 5a. is formed to engage with.

Next, the operation of the iron storage case 1 constructed as described above will be explained with reference to FIGS. 3 to 8.

FIG. 3 shows a locked state of the case body 3 and case lid 5; FIG. 4 shows a cross-sectional view taken along line A-A in FIG. 3; and FIG. 5 shows a vertical cross-sectional view taken along line B-B in FIG. In the figure, the locking member 19 is locked by the elastic force of the compression spring 21.
is urged in the locking direction and the operation dial 15 is urged to rotate clockwise, so that the cam surface 17a is held in a non-sliding state with respect to the cam protrusion 19b. In this state, after storing an uncooled or cooled iron (not shown) in the heat shield 14 through the upper opening of the case body 3, the case lid 5 is attached to the hinge part 7 with respect to the case body 3.
When the locking member 19 is operated to close around the shaft portion 15a, the locking member 19 moves inward of the case body 3 around the shaft portion 15a while resisting the elastic force of the compression spring 21 as the hook 19a comes into contact with the engaged portion 5a. After rotating in the lock release direction and the hook 19a getting over the engaged portion 5a,
The elastic force of the compression spring 21 causes the hook 19a to return to its original position and engage the locking hole 5b. At this time,
The tip of the leaf spring 13 comes into contact with the engaged portion 5a and is elastically deformed, and biases the case lid 5 in the opening direction with an elastic force corresponding to the amount of elastic deformation.

Next, FIG. 6 shows the unlocking action between the case body 3 and the case lid 5, FIG. 7 shows a cross section taken along line C-C in FIG. 6, and FIG. 8, when the operation dial 15 is rotated in the counterclockwise direction shown in FIG. 6 against the elastic force of the compression spring 21 in the locked state, the cam body 17 is rotated about the shaft portion 15a. The cam surface 17a is rotated counterclockwise to bring the cam surface 17a into sliding contact with the cam protrusion 19b. As a result, the locking member 19 swings inward of the case body 3 (in the unlocking direction) around the shaft portion 15a against the elastic force of the compression spring 21, and the hook 19a engages with the locking hole 5b. is canceled. At this time, since the case lid 5 is biased in the opening direction by the leaf spring 13 that comes into contact with the engaged portion 5a when the hook 19a is engaged with the locking hole 5b, the case lid 5 is pressed against the locking hole 5b. When the engagement of 19a is released, it is automatically released by the elastic force of the leaf spring 13.

Note that when the counterclockwise rotation of the operation dial 15 is released after the case lid 5 is opened, the operation dial 15 is rotated clockwise by the elastic force of the compression spring 21 and the cam protrusion 19b is rotated. The sliding contact of the cam surface 17a against the locking member 19 is released, and the locking member 19 is swung in the unlocking direction.

In this way, in this embodiment, the locking member 19 swings in the unlocking direction as the operation dial 15 rotates.
When the hook 19a is disengaged from the locking hole 5b, the case lid 5 can be automatically opened by the elastic force of the leaf spring 13. This makes it possible to open the case lid 5 with respect to the case body 3 with one hand, thereby improving operability.

[Effects of the Invention] Therefore, the present invention can provide an iron storage case in which the case lid can be opened with one hand and the operability can be improved.
