Description

[Detailed Description of the Invention] The present invention relates to a cooking appliance in which a handle is bolted to a door for opening and closing an opening in a heating chamber.

A conventional cooking device of this type is as shown in FIGS. 1 and 2, where 1 is the main body of the cooking device, 2 is an operating section, and 3 is a heating chamber (not shown) disposed within the main body 1.
a door that opens and closes the front opening of the door; 4 is the front plate of the door;
Reference numeral 5 indicates an opening formed in the front plate through which a threaded portion of a bolt to be described later is inserted; 6 a handle for opening and closing the door 3; and 7 and 8, the handles are connected to the door 3
Bolts and nuts for fixing to the front plate 4 of
The head 7a of the bolt and the nut 8 both have a hexagonal shape.

Reference numeral 9 denotes a hexagonal hole formed in the handle 6, which has a hexagonal cross section along the line a-a (FIG. 2), and whose cross-sectional dimensions become smaller toward the right side. The end 9a of the hexagonal hole is connected to the bolt 7.
The dimensions are such that the head 7a of the head 7a just fits therein. 10 communicates with the hexagonal hole 9 and connects with the bolt 7.
A bolt hole 11 through which the threaded portion 7b of the bolt 7 is inserted is a hole in the hexagonal hole 9 where the head 7a does not exist when the head 7a of the bolt 7 is fitted into the end 9a of the hexagonal hole 9. An elastic spacer 13 fills the space 12, and 13 is a decorative metal fitting attached to the surface of the handle 6 to hide the spacer and the like.

When attaching the handle 6 to the front plate 4 of the door 3, first insert the threaded portion 7b of the bolt 7 into the bolt hole 10 from the hole 9 until the head 7a fits into the end 9a of the hole 9. Insert it. Next, a spacer 1 is added to fill the remaining space 12 of the hole 9.
1, then attach the decorative metal fittings 13.

Thereafter, when the protruding portion 7b' of the threaded portion 7b of the bolt 7 is inserted into the opening 5 of the front plate 4 until the end surface 6a of the handle 6 comes into contact with the front plate 4, and the nut 8 is tightened, the handle 6 is moved to the door 3. It is securely fixed to the front plate 4.

Here, due to the presence of the spacer 11, when the nut 8 is tightened, the bolt 7 is undesirably moved in the detachment direction.
That is, it does not move to the left (FIG. 2), and therefore the nut 8 can be easily tightened.

However, such a structure requires separate parts such as the spacer 11, which increases the cost.
There is a disadvantage that a step is required to insert the spacer 11 into the space 12, resulting in poor workability.

The present invention has been devised in view of this point, and embodiments of the present invention will be described below with reference to FIGS. 3 to 5. Incidentally, the same parts as in the conventional example are denoted by the same reference numerals, and the explanation thereof will be omitted.

In FIGS. 3 to 5, reference numeral 9 denotes a recess formed in the handle 6, and the size of the recess in a cross section perpendicular to the page (FIG. 3) becomes smaller toward the right side. The top side is cut out. The end 9a' of the recess 9' is dimensioned so that the head 7a of the bolt 7 just fits therein. Further, the bolt hole 1 is inserted into the recess 9'.
0 is connected. Reference numeral 14 denotes a spring rib which is integrally molded with the handle 6 and whose tip 14a reaches the notched area above the recess 9'.

To explain the rib 14 in more detail, as the threaded portion 7b of the bolt 7 is inserted into the bolt hole 10 from the recess 9' (during insertion), the rib 14
is pressed by the head 7a of the bolt 7 and is bent in the direction of arrow A in FIG. When the above-mentioned pressure is released, the rib 14 is moved in the direction of arrow B.
It returns in the direction shown by the solid line. In this case, the tip of the rib 14 is located at the front surface of the upper end of the head 7a, and therefore, the rib 14 is positioned so that when the bolt 7 moves to the left (FIG. 3), the threaded portion 7b of the rib 14 is inserted into the bolt hole 1.
This suppresses deviation from 0. The nut 8 can then be easily tightened as described above.

As is clear from the above description, according to the present invention, in a cooker in which a handle is bolted to a door for opening and closing an opening of a heating chamber, a bolt hole is formed in the handle through which a threaded portion of the bolt is inserted; In addition, while the threaded portion is being inserted into the bolt hole, it is pressed in one direction by the head of the bolt, and when the insertion is completed, the pressing is released and the screw returns in the opposite direction to the front surface of the head. Since the spring rib that is positioned and prevents the threaded portion of the bolt from coming off the bolt hole is integrally molded on the handle, there is no need to provide a separate part such as a conventional spacer, thus reducing costs. This makes it possible to easily improve work efficiency.

Claims (1)

[Scope of utility model registration request] In a cooking appliance in which a handle is bolted to a door for opening and closing an opening of a heating chamber, a bolt hole is formed in the handle through which a threaded portion of the bolt is inserted, and while the threaded portion is inserted into the bolt hole, The head of the bolt presses it in one direction, and when the insertion is finished, the pressure is released and it returns to the opposite direction to be located in front of the head, and the threaded part of the bolt separates from the bolt hole. A cooking utensil characterized in that the handle is integrally molded with a spring-like rib that suppresses the above.
