Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook structure in a lidded container such as a rice cooker and a pot.

[0002]

2. Description of the Related Art In a container with a lid such as a rice cooker or a pot, the lid is urged in the opening direction by a hinge spring, and a hook structure is provided to engage the lid with the container body. This hook structure is engaged by the hook when the lid is closed, and when the lid is opened, the hook is operated from the outside to release the engagement.

In order to provide such a function, a conventional hook structure has a hook for engaging a lid, a hook lever for operating the hook from outside, and a biasing force applied to the hook in the engaging direction. A configuration combining a spring to be applied has been generally adopted.

Accordingly, an object of the present invention is to provide a hook structure in which a hook and a member for operating the hook are formed as a single component in order to reduce the number of parts and to simplify the assembling work.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a container in which a hook is slidably and outwardly applied to a guide groove provided on an upper surface of a front portion of a container body. A hook provided on the hook is detachably engaged with a part of the lid, a stopper is provided on the hook, and an engagement portion with the stopper is provided on the guide groove.

[0006]

When the lid is closed, hook hooks engage with a part of the lid to hold the lid closed. To open the lid, press the hook with your fingertip to release the hook from the lid and open the lid automatically. Since the stopper piece of the hook is engaged with the engaging portion of the guide groove, the hook is prevented from being pulled out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment shown in FIGS. 1 to 5 shows a lid hook structure of a rice cooker. The lid 3 is attached to the rear end of the jar main body 1 by being freely opened and closed by a hinge pin 2 and urged in the opening direction by a hinge spring (not shown).

A front-rear guide groove 5 is formed on a front upper surface of a shoulder member 4 which constitutes a part of an exterior body of the jar body 1 (see FIG. 2).
Is provided.

The guide groove 5 has guide ribs 6 on the inner surfaces of both side walls.
Are provided, and an engagement groove 7 is provided in a portion in contact with both side walls at the bottom of the guide groove 5. A spring receiving projection 9 for receiving the coil spring 8 is provided on the inner wall of the guide groove 5. The engagement groove 7 engages with a stopper piece 16 described later.
Department.

The hook 10 is slidably housed in the guide groove 5. At the rear end of the hook 10, a claw piece 11 rising upward is provided. The inside of the hook 10 has a lower surface and a rear end surface open to form a spring storage portion 12. A spring receiving projection 13 is provided on the inner wall of the spring storage portion 12. On the outer surfaces of both side walls of the hook 10, a groove 14 that fits into the guide rib 6 is provided from the rear end to the middle. In addition, an inverted L-shaped slit 15 is provided in a range from the center of the lower surface of each side wall of the hook 10 to the front wall, and a stopper piece 16 separated from the side wall by the slit 15 and integrated with the front wall is provided. . The stopper piece 16 is flexible and has a claw 1 at its tip.
7 is formed downward.

As shown in FIG. 4, the hook 10 accommodates a coil spring 8 in its spring accommodating portion 12, and the both ends of the coil spring 8 are fitted to the guide groove 5 and the spring receiving projections 9 and 13 of the hook 10, respectively. The groove 14 of the hook 10 is fitted to the guide rib 6 of the guide groove 5, and the stopper piece 16 is further bent and pushed into the guide groove 5.

When the pawl 17 of the stopper piece 16 is fitted into the engagement groove 7 of the guide groove 5, it engages with the engagement groove 7 slidably by its own elasticity.

On the other hand, the inner cover 18, which is a component of the lid 3, is provided with an engaging portion 19 corresponding to the above-mentioned hook 10, and the claw 11 of the hook 10 is engaged with this, and the lid 3 is closed. To hold.

When opening the lid 3, the tip of the hook 10 is pushed with a fingertip. Then, the hook 10 becomes the coil spring 8
Is pressed while being compressed, the claw piece 11 is disengaged from the engagement portion 19, and the lid 3 is automatically opened.

When the finger is released, the hook 10 is pushed back by the force of the coil spring 8, but the hook 17 of the stopper piece 16 is engaged with the end of the engagement groove 7, so that the hook 10 is prevented from coming off.

Next, a second embodiment shown in FIGS.
The hooks 17 of the stopper pieces 16 of the hooks 10 are bent outward, and correspondingly, the engagement grooves 7 of the guide grooves 5 are also provided at the lower ends of both side walls. The engagement groove 7 is
It becomes an engaging portion of the upper piece 16. Other configurations and actions
This is the same as in the first embodiment.

In the third embodiment shown in FIGS. 10 to 13, a stopper piece 16 'extending rearward from the front wall is provided on the lower surface of the spring storage portion 12 of the hook 10, and the stopper piece 1 is provided.
6 'is provided with a long engagement groove 20 in the front-rear direction.

On the bottom surface of the guide groove 5, there is provided a small projection 21 which fits into the engagement groove 20.
The hook 10 is prevented from coming off by the engagement of the engagement groove 20. The small projection 21 is the stopper piece 1
6 '.

The other constructions and operations are the same as those of the first embodiment.

[0020]

As described above, according to the present invention, the hook which is removably engaged with the lid is provided with the stopper piece which is engaged with the container body, and the hook is engaged with the container body by the stopper piece. Since the stopper is prevented from falling off, the engagement and disengagement with the lid can be performed with only one hook. Therefore, the number of parts is reduced and the assembling work is very easy.
