Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a lid locking mechanism for containers such as electronic jars, and in particular to a mounting structure for a hookset provided at the front of the lid.

(Prior art and its problems) Conventionally, the lid of a container such as an electronic jar is composed of a front lid and a back lid, which can be opened and closed with respect to the container body using a rear hinge mechanism and a front lock mechanism. It is said that

The hook set in the locking mechanism includes a foot lever provided with a locking portion that engages with a pawl provided on the container body, a supporting shaft rotatably provided to support the foot lever, and a foot lever that is attached to the container body. It is composed of a hook spring that is biased in the direction of engagement with a provided claw portion, and is fixed to the lid body with screws or the like via a hook holder.

For this reason, fixing parts such as a hook holder and screws are required, resulting in complicated assembly and poor productivity.

(Means for Solving the Problems) The present invention has been made to solve the above problems, and the footset is disposed in the recess of the lid body, and the upper lid and lower lid constituting the front lid of the lid body are connected to each other. The support shaft is held by the lid, one end of the hook spring is locked with the lower lid, and the position of the hook lever is regulated by the back lid that is fitted into the front lid.

(Example) Hereinafter, an example of the present invention will be described based on the accompanying drawings.

FIG. 1 shows a rice cooking jar 1, and this rice cooking jar 1 is roughly composed of a lid body 2 and a container body 3.

As shown in FIG. 2, the lid body 2 consists of a front lid 6 with a lower lid 8 fitted inside an upper lid 7, and a back lid 10 fitted inside the top lid 6.
A pin 12 is fixed in the center of the container, and an inner lid 14 is removably attached via a support 13, and can be opened and closed with respect to the container body 3 by a rear hinge mechanism 30 and a front lock mechanism 20. has been done.

Further, the upper lid 7 is formed with a substantially half-moon-shaped notch 7a, and the lower lid 8 that closes the notch 7a includes:
A recess 8a is formed further inward from a portion corresponding to the notch 7a, and an opening/closing handle 9 is formed by the notch 7a and the recess 8a.

As shown in FIG. 3, the footset 21 is composed of a foot lever 22, a support shaft 23, and a hook spring 24. , 22b, and the hook spring 24 is mounted approximately at the center of the support shaft 23, with both ends 24a and 24b protruding outward at a predetermined angle. In addition,
A locking portion 22b is formed at the lower end of the foot lever 22.

Further, recesses 25 and 27 for mounting a footset 21 are formed in the upper lid 7 and the lower lid 8, respectively.
A pair of opposing bearing grooves 26, 26 are formed on the lower end side of the side wall 25a of the recess 25 of the upper lid 7, and a pair of protrusions 28, 28 are formed on the upper part of the lower lid 8, corresponding to the bearing grooves 26. and the lower lid 8 is replaced with the upper lid 7.
The bearing grooves 26 are fitted into the entrance portions of the bearing grooves 26, 26 in a state where the bearing grooves 26, 26 are fitted into the bearing grooves 26, 26, respectively.

Hereinafter, a method of assembling the lid body 2 having the above structure will be explained with reference to FIGS. 3 and 4.

First, the support shaft both ends 23a, 23a are engaged with the bearing grooves 26, 26 of the outer lid 7. Next, lower lid 8
One free end 2 of the hook spring 24 is attached to the upper surface of the
4b is locked, fit the protrusions 28, 28 into the entrance portions of the bearing grooves 26, 26 of the upper lid 7,
The lower lid 8 is fitted inside the outer lid 7.

As a result, both ends 23a, 23a of the support shaft 23
is held by the bearing groove 26 of the upper lid 7 and the protrusion 28 of the lower lid 8. Further, the other free end 24a of the hook spring 24 abuts on the inside of the hook lever 22, and the hook lever 22
Turn the foot lever 2 in the direction of arrow a in the figure.
The lower part of 2 is located in the recess 27 of the lower lid 8.

Next, the side part of the back cover 10 is brought into contact with the lower inner surface of the hook lever 22, and the back cover 10 is pushed against the hook spring 24 in the direction of arrow b in FIG. The upper cover 7, lower cover 8, and back cover 10 are assembled into one body in the state shown in FIG.

This allows the free end 2 of the hook spring 24 to
4a is forcibly moved in the direction of arrow a' to generate a twisting moment, which constantly biases the hook lever 22 in the direction of arrow a.

Therefore, when the lid body 2 is closed, the lower end locking portion 22b of the lid lever 22 engages with the claw portion 29 provided on the container body 3 to lock the lid body 2, as shown in FIG.

When opening the lid 2, grasp the opening/closing handle 9 and press the top of the lid lever 22.
2 rotates in the direction of arrow a', the engagement between the lower end locking part 22b of the lid lever 22 and the claw part 29 of the container body 3 is released, and the lid body 2 can be opened.

In the embodiment described above, the hook spring 24 that urges the hook lever 22 in the direction to constantly engage with the claw portion 29 provided on the container body 3 is a coil spring wound around the support shaft 23, but the hook spring 24 is not limited to this. isn't it.

(Effects of the invention) As is clear from the above explanation, according to the container lid locking mechanism according to the present invention, fixing parts such as a hook pedestal and screws for fixing the lid lever are not required when assembling the lid lever. Therefore, the number of parts is reduced, assembly is simple and easy, and the production process can be simplified.
