Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an outer lid locking device for a pot.

[Conventional technology]

The outer lid locking device of a pot is usually provided on the front surface of the outer lid in consideration of ease of operation. A water supply part upper cover projecting forward in a beak shape is integrally formed on the entire surface of the outer lid. For this reason,
The conventional lock device is built into the water supply section upper cover, and has its operation buttons protruding from both sides of the upper cover.

To open the outer lid of a pot equipped with a locking device such as the one described above, the user presses both operation buttons with his thumb and forefinger to release the lock, and then lifts the outer lid backwards.

[Problem that the invention attempts to solve]

As mentioned above, the water supply part upper cover has conventionally been provided integrally with the outer lid, but functionally it is not necessarily necessary to provide both together. Therefore, from a functional or design point of view, it is also possible to separate the two, fix the upper cover to the water supply part, and adopt a configuration in which only the outer cover is attached so that it can be opened and closed.

When such a configuration is adopted, it becomes necessary to incorporate the locking device, which has conventionally been incorporated inside the upper cover, into the outer cover.

However, the outer lid separated from the top cover has
There is not enough space to incorporate a locking device. Nevertheless, it is necessary to ensure that the locking device is as easy to operate as before, or even better than before, so there are problems that cannot be solved by simply repurposing the conventional pot locking device. be.

Therefore, this invention solves the above problems by devising a new locking device, and provides a lock with good operability and ease of assembly in a pot where the upper cover of the water supply section is separated from the outer lid and provided independently. The purpose is to provide a device.

[Means for solving problems]

In order to solve the above problems, this invention has a pot in which the upper cover 2 of the water supply part 1 is attached to the shoulder body 3, and the outer cover 4 is attached to the shoulder body 3 so as to be openable and closable, and the hook 5 is connected to the operating member 6. The hook 5 is inserted from the outside into a hook insertion hole 8 formed in the outer cover 4, and the support shaft 9 of the hook 5 is inserted into both ends of the hook insertion hole 8 on the back side of the outer cover. The other end of the spring 11 supported by the provided bearing groove 10 and engaged with the hook 5 is pressed against the inner circumferential surface of the outer cover 4, and the other end of the presser foot 12 is fitted onto the support shaft 9. is fixed to the back surface of the outer lid 4, a knob 13 formed at the upper end of the operating member 6 of the hook 5 is made to protrude from the upper surface of the outer lid 4, and a locking member 7 of the hook 5 is formed on the shoulder body 3 or the upper cover 2. It is configured to be removably locked in the locking pawl 14.

[Effect]

When the knob 13 protruding from the top surface of the outer lid 4 is operated, the hook 5 tilts while compressing the spring 11.
The locking member 7 is disengaged from the locking pawl 14, and the outer cover 4 can be unlocked. Further, when the outer lid 4 is closed, the hook 5 descends while compressing the spring 11, and the locking member 7 engages with the locking claw 14.
