Description

[Detailed Description of the Invention] The present invention relates to a handle structure of a lid with a handle for a rice cooker, a heat insulator, etc.

This type of handle is often made of synthetic resin together with the lid, and the handle portion is hollow in order to reduce the amount of material used.

For this reason, the handle has a U-shaped cross section with an open upper surface, and this open part is closed with a covering plate, and a plurality of engagement means provided on the covering plate are formed on the inner surface of the open part of the handle. By engaging with the engaging portion, the covering plate can be attached to the handle in a state where the upper open portion is closed.

However, in the conventional type, one longitudinal end of the cover plate is engaged with the longitudinal end of the opening of the handle (for example, near the shaft support of the lid body), or the other end is engaged with the removal prevention state. Since they do not fit together, they have the disadvantage of being easy to come off from this end.

The purpose of the present invention is to prevent the covering plate from being accidentally removed by engaging the handle with both ends of the covering plate in a manner that prevents it from being removed, and to enable the covering plate to be removed. do.

The technical means of the present invention taken to achieve the above object is to prevent the engaging tongues provided at both ends of the covering plate 12 in the longitudinal direction from being pulled out from the secured portion of each corresponding handle. The engaging tongue piece at one end is a pair of engaging tongue pieces 25, 25 arranged in parallel in the width direction of the cover plate, and these engaging tongue pieces 25, 25 are arranged in parallel in the width direction of the covering plate. A through hole 22 is formed at the bottom of the upper end opening 11, and the pair of engaging tongue pieces 25, 25 is inserted, and these engaging tongues 25, 25 engage with the end side 23 in a manner that prevents them from being removed.

According to the above technical means of the present invention, both end portions of the covering plate 12 are engaged with the retaining tongue piece 18 and the pair of engaging tongue pieces 25, 25 to prevent removal, and are attached to the handle 10, Moreover, since the deformation of the engagement tongues 25, 25 in the disengagement direction is usually prevented by the square blocks 24, 24, the covering plate 12
hard to come off.

On the other hand, when removing the cover plate 12, the tips of the retaining tongues 25, 25 projecting downward from the through hole 22 are pinched to narrow the distance between the lower portions of these tongues.

As a result, the engaging portions of the engaging tongues 25, 25 are located in the space between the square blocks 24, 24, and in this state, the covering plate 1
When the corresponding part 2 is pushed in, the end side 23 and the engaging tongue pieces 25, 25
After that, the engagement of each engaging portion can be disengaged one after another.

As described above, according to the present invention, the cover plate 12 does not come off accidentally, and can be easily removed when repairs or the like are required.

Hereinafter, embodiments of the present invention will be described based on the drawings.

The lid body of the example shown in the figure is for a heat retention type rice cooker,
The lid is rotatably supported at the upper end of one side of the container 1, and covers the upper end opening of the container and the rice cooker in a single-opening manner.

A hook 2 is attached to the opposite side of the pivot support and engages with an engagement base 3 disposed on the other side of the vessel body 1, thereby holding the lid body A in a closed state.

The lid A is protected from the main body 4, the lower surface closing plate 5, the heat insulating material 6 built in between them, the heat generating device 7, etc., but the main body 4
A handle 10 extending from the pivot support 8 to the hook accommodating portion 9 is integrally installed on the handle 10, and its cross section is approximately U-shaped with an upward opening.

The upper edge opening 11 of this handle reaches the hook accommodating part 9 from the shaft support 8, but this is closed by a cover plate 12, and a through hole of an appropriate size is formed on one side of the cover plate 12 on the side of the hook 2.
3 is formed, and the operating portion 14 of the hook 2 protrudes from the through hole.

In addition, in order to fit the covering plate 12 into the opening 11 of the handle 10,
A plurality of ribs 16.1 are provided on the inner surfaces of the side walls 15, 15 of the handle 10.
6 is provided in a protruding manner, and its top portion is set an appropriate amount below the upper end of the side wall 15.15 in accordance with the thickness of the covering plate 12.

Further, near the shaft support 8 of the handle 10, an engaged portion 17 is provided that protrudes from the bottom toward the opening 11, and an engaging tongue piece is hung from an appropriate position near one side of the cover plate 12. 1
8 corresponds to the engaged portion.

Further, a plurality of engaged step portions 19, 19 are arranged on the inner surfaces of the side walls 15, 15 of the handle 10 at appropriate pitches, and a plurality of engaging tongues are provided from both longitudinal edges of the cover plate 12 in correspondence with these. Piece 2
0.20 is hanging down.

Next, the hook storage part 9 of the handle 10 is located at the free end of the lid A, as shown in FIG. Its outer edge becomes an end side 23 having a hook-shaped cross section, and a pair of square blocks 24, 24 face this at an appropriate distance.

This end side 23 constitutes one side end of the opening 11, and the square blocks 24.24 are connected to the inner surface of the side wall 15.15 and are spaced apart from each other at appropriate intervals. The upper end corner part is an inclined surface B.

On the other hand, a pair of engaging tongues 25, 25 hang down from appropriate positions of the portion of the cover plate 12 that closes off the hook accommodating portion 9, and are engaged with the hook-shaped cross section of the end side 23.

As described above, the cover plate 12 is fitted into the opening 11 with its both edges abutting one side edge or edge 23 of the shaft support 8, and both longitudinal edges abutting the tops of the ribs 16, 16. Furthermore, the engagement between the engagement tongue piece 18 and the engaged part 17, the engagement between the engagement tongue pieces 20, 20 and the engaged step part 19.19, and the engagement between the engagement tongue pieces 25, 25. By engaging with the edge 23,
The cover plate is fitted and fixed in the opening 11 of the handle 10.

Each part of the lid A, including the handle, is integrally injection molded from synthetic resin, and the cover plate 12 is also integrally molded.

Furthermore, in order to fit the two, first, the edges of the covering plate 12 on the shaft support 8 side are aligned and fitted into the opening 11, and then the engaging tongue piece 1 is inserted into the opening 11.
8 and the engaged portion 17, and further engage the engaging tongue pieces 20, 2.
0 and the engaged step portion 19. ．． 19 As we engage each other,
The cover plate 12 is sequentially fitted into the opening 11 of the handle 10 toward the hook 2 side, and finally, when the pair of engaging tongue pieces 25 are inserted toward the through hole 22, the tips thereof meet the square block 24. .24, these engage the tongues B, B, which bend inwardly and intrude while bending backwards, and when the edge of the cover plate 12 abuts the edge 23, these engaging tongues The hooked portions of the pieces 25, 25 coincide with the hooked portions of the end side 23 and engage with each other;
and a pair of square blocks 24.24 (third
figure).

Now, the retaining tongue pieces 25, 25 are attached to the square blocks 24, 24.
Since the retaining tongues 25, 25 are prevented from being bent backwards, they are placed in a state where they cannot be easily removed.

That is, the fitting between the covering plate 12 and the handle 10 has sufficient strength.

For repair and inspection, the tips of the engaging tongues 25, 25 are bent toward each other and positioned between the rectangular tabs 24, 24, and then bent backward while the covering plate 12 is bent. When this is done, the hook-shaped portions of these engaging tongues 25, 25 come off from the hook-shaped portion of the edge 23, and the covering plate 12 can be sequentially removed from this edge.
