Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a lid fixing device for a cooker used in general households.

Conventional technology A conventional cooker of this type is, for example,
As shown in Publication No. 11431, it had a structure as shown in FIGS. 4 and 5.

That is, FIG. 4 shows a perspective view of a cooking device equipped with a conventional lid opening/closing structure, and by pressing the lever push button 2 that presses the lever 1, the lower end of the lever 1 engages with the cooking device main body. is removed, and the lid 3 is removed from the shaft 4.
Rotate around the center to open it and take out the contents. In addition, in the state shown in FIG. 4, the cooking device main body 5 and a part of the lever 1 are fitted, and the lid body 3 and the cooking device main body 5 are fitted together.
are combined, and the entire cooking device body 5 can be carried by holding the lid body 3.

FIG. 5 shows an enlarged view of the main part of the structure near the lever, and the lever 1 has a lever push button 2 attached thereto. The lever 1 is bent so that both sides face each other to form a side wall 1a, and a bearing plate 6 is placed inside the both side walls 1a.
It is set up so that it has a plane parallel to. Further, a spring 7 is provided on the inner surface of the bearing plate 6 so that one end is in contact with the lever 1 and the other end is in contact with the bearing plate 6. The shaft 8 passes through the hole and the hole on the side of the bearing plate 6.
is provided, and the lever 1 is pushed up by the spring 7.

Further, reference numeral 9 denotes a handle disposed on the upper surface of the lid body 3 in the diametrical direction. Reference numeral 10 denotes a protrusion provided on the side of the cooking device main body 5, and the projecting portion 10 is configured to engage with and disengage from the portion of the lever 1 that fits into the cooking device main body 5. Reference numeral 11 denotes a cover on the lever 1 side, and the upper inner surface is sloped so that the tip of the lever 1 can easily enter the cover. Further, the lid body 3 was configured such that one end was supported by a shaft 4 and the other end was supported by a lever 1.

Problems to be Solved by the Invention However, with such a structure, the lever 1 side swings from side to side due to the gap between the shaft 4 and the lid 3 or the cooker body 5, or due to dimensional variations, and the engaging part of the lever 1 However, since there were problems such as riding up on the protrusion 10, a large dimensional allowance was provided in the left and right direction, which caused wobbling when being carried.

For this reason, it is necessary to use parts such as the cover 11 to restrict the position of the lever 1 by inclining the inner surface, etc., and to engage it with the protrusion 10, which requires separate parts, takes time to assemble, and The cover 11 and the like need to be strong and have a large shape, which poses problems in appearance as well as contact with the body when carried.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a lid body which is provided on the cooking device main body so as to be openable and closable, one end side is removable from the cooking device main body side, and the other end is detachable from the cooking device main body side. a lever whose side is pressed, a pair of opposing protrusions provided on the surface of the cooker main body on the lever side of the lid, and a pair of protrusions that slide on the inner surface of the protrusions, and It has a protruding part that engages with a hole provided in the engaging/disengaging part on the cooking appliance main body side, and includes a rib arranged on the inner side of the upper surface of the cooking appliance main body.

Effect According to the above configuration, a set of protrusions is provided on the lid body,
Ribs are provided on the cooker body that guide this protrusion by sliding, and when the lid is closed, the protrusions and ribs are used to align the position, which eliminates side-to-side wobbling of the lid. .

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 1 to 3, 20 is the cooking device main body, and 20a is a protrusion provided on an angular rib 20b provided at the top of the cooking device main body 20.
Reference numeral 21 denotes a lid, which is provided on the cooking device main body 20 so as to be openable and closable. 21a, 21a are the lid body 21
This is a set of protrusions that are provided in the cooker body 20 and protrude toward the cooking device main body 20 side. 22 is a lever, this lever 2
2 has a hole 22a on one end side that can be engaged with and detached from the cooking device main body 20 side, and the other end side is operated by pressing.
The hole 22a engages with and disengages from the protrusion 20a. 2
3 is a spring, and this panu 23 has a repulsive force when the lever 22 is pressed.

The pair of protrusions 21a, 21a are connected to the lever 2.
2 and are arranged opposite to each other on both sides. The inner surfaces of the projections 21a, 21a and the outer surface of the rib 20b slide, and each tip is provided with a guiding slope. 24 is the lid body 21 and the cooking device main body 20
The lid body 21 rotates around an axis 24 that connects the two.

The operation of the above configuration will be explained next.
FIG. 2 shows a rib 2 between a pair of protrusions 21a, 21a.
Indicates that 0b is inserted. d is the gap on one side during this insertion, and if this d is made small enough,
For example, the shaft 24 and the lid 21 or the cooking device main body 20
Even if dimensional variations occur, the lid body 21 will engage with the cooking device main body 20 without swinging from side to side.

Effects of the invention As described above, according to the invention, a set of protrusions is provided on the lid side, and a rib is provided on the cooker body side to be inserted between the set of protrusions, so that when the lid is closed, Since positioning is performed using protrusions and ribs, it is possible to reliably prevent the lid from swinging from side to side due to variations in the dimensions of the shaft that connects the lid and the cooker body. The lever can be reliably engaged with the cooker main body by the guide of the set of protrusions and the ribs provided on the cooker main body side.
Furthermore, since the ribs on the side of the cooker are placed on the inside of the top of the cooker, there is no need for a conventional cover, etc. As a result, the appearance is clean, so there is no need to protrude when carrying. This has practical effects such as eliminating the need for contact with the body.
