The case body (9a) has a main body (92) having an open upper end for accommodating the burner (97) and the like, and covers the upper end of the main body (92) so that the burner (97) is exposed. With Gotoku (9
It consists of a soup saucer (93) on which 6) is placed. The flange (94) protruding from the upper end of the main body (92) to the outer peripheral side is placed on the upper surface of the countertop (9), so that the case body (9a) is supported by the countertop (9). To be done.

The main body (92) is provided with a plurality of bolts (9c) (9c) projecting to the left, right, front and rear.
Each of these bolts (9c) (9c) is a substantially horizontal posture that penetrates from the inside to the outside with respect to the side wall (95) facing the peripheral surface of the opening (90) in the main body (92). Is attached to. When installing the drop-in stove (900), with the main body (92) dropped into the opening (90) and the flange (94) placed on the upper surface of the countertop (9), Tighten each of the bolts (9c) (9c) so that they move toward the outside of the side wall (95). As a result, each of the bolts (9c) (9c) comes into contact with the peripheral surface (91) of the opening (90). By this contact, the main body (92) is fixed to the counter top (9).

After that, when the main body (92) is covered with the soup saucer (93), and further the gotoku (96) is placed on the soup saucer (93), the attachment of the drop-in stove (900) is completed. To do. In this thing, bolt (9c) (9c)

[0006]

However, in this conventional fixing structure, the bolts (9c) (9) which come into contact with the above-mentioned peripheral surface (91).
Each of c) penetrates the side wall (95) and projects inwardly, and the amount of projection to the upper region inside the main body (92) is large. Therefore, for example, when changing the above-mentioned soup saucer (93) to a deep one, as shown by the chain double-dashed line in FIG.
(93) hits the bolts (9c) (9c) and cannot be attached to the main body (92).

An object of the present invention is to provide a fixing structure for a drop-in stove in which the amount of protrusion to the upper area inside the case body is suppressed.

[0008]

According to a first aspect of the present invention, there is provided a "case body which is dropped into an opening of a countertop and is supported by an upper surface of the countertop, and the case body". A lower end portion is attached to a side wall facing the peripheral surface of the opening, and the piece is displaceable toward the outside of the side wall with the lower end portion as a center; A pressing member which is mounted in a penetrating state so as to be movable toward and which presses between the upper end portion and the lower end portion of the piece by the movement, and which is displaced outwardly. The upper end of the one portion abuts on the peripheral surface of the opening ”.

In this structure, when the pressing member moves from the inside to the outside of the side wall, the pressing member presses between the upper end portion and the lower end portion of the piece. . Due to this pressing, the piece is displaced outwardly around the lower end. Then, as the displacement continues, the upper end of the piece contacts the peripheral surface of the opening. By this contact, the case body is fixed to the counter top.

According to the invention of claim 2, in which the lower end is rotatably connected to the side wall, the lower end is rotated with respect to the side wall.
The piece is displaced outward of the side wall. The lower end may be fixed to the side wall and the piece may be displaced by its elastic deformation or plastic deformation.

According to a third aspect of the invention, in which "a projecting portion formed on the other end is inserted into a hole formed on one of the lower end portion and the side wall", the above-mentioned insertion causes Rotation of the lower end with respect to the side wall is ensured. As in the invention of claim 4, further comprising: a protrusion that protrudes toward the side wall from between the upper end and the lower end of the piece, the protrusion with respect to the side wall. It may penetrate so as to be movable inward and outward, and be prevented from escape from the side wall. ”

In this structure, the projecting piece moves outward as the piece is displaced outward. Then, since the projecting piece is prevented from coming out of the side wall, the displacement of the piece portion more than a predetermined amount is prevented. According to a fifth aspect of the present invention, “the engagement portion is further provided on the side wall side of the piece portion, and the piece portion engages with the side wall in a posture along the side wall. The engaging portion may be forcibly released from the engagement by the pressing of the one piece by the pressing member.

In the posture in which the piece portion is along the side wall, the engaging portion engages with the side wall, so that the piece portion is maintained along the side wall. Then, when the piece is pressed by the pressing member, the engagement of the engaging portion with the side wall is forcibly released, and the piece can be displaced outward. According to a sixth aspect of the present invention, in the "the pressing member includes a bolt that is screwed in a substantially horizontal posture with respect to the side wall", the bolt is tightened inside the side wall by tightening the bolt. To move outwardly and press the piece.

[0014]

As described above, in the invention of claim 1, since the pressing member is located below the upper end of the piece that abuts on the peripheral surface, the pressing member in the vertical direction. The amount of protrusion of the pressing member to the upper region inside the case body is suppressed as compared with the conventional one in which the bolt is located at the same height with respect to the contact position between the and the peripheral surface. In particular, when the thickness of the countertop is small, the effect of suppressing the protrusion amount becomes remarkable.

Further, since the outward displacement of the upper end portion is greater than the outward displacement of the pressing member, the length of the pressing member in the moving direction is longer than that of the conventional one. It can be small. Also in this respect, the amount of protrusion of the pressing member in the upper area of the inside can be suppressed. In the invention of claim 2, since the lower end of the piece is rotatably connected to the side wall, the lower end is fixed to the side wall and the piece is elastically deformed or plastically deformed. The force required to press the pressing member is smaller than that required to displace due to deformation.

According to the third aspect of the invention, the lower end and the side wall can be pivoted relative to the side wall by inserting the protrusion formed in the other end into the hole formed in the one side wall. Is ensured, the structure for the rotation is simplified as compared with the type in which the rotation is ensured by using a shaft. In the invention of claim 4, since the displacement of the piece mounted so as to be rotatably displaced with respect to the side wall is prevented from being larger than a predetermined value, it is possible that the piece is hung downward or dropped. Therefore, the work of attaching the drop-in stove to the opening becomes easy.

According to the invention of claim 5, the piece is maintained in a state along the side wall by the engagement of the engaging portion with the side wall, so that the mounting operation is further facilitated. In addition, the piece does not get in the way when packing the drop-in stove at the time of shipping or the like, and the packing operation or the like becomes easy.

The middle of the flap body (3a) (3a) in the vertical direction is the bolt.
(4) Pressed by each of (4), these flap bodies (3
Each of a) and (3a) has a side wall (2) centered around the bent piece (33) (33).
Displaced to the outside of 1a). Due to this displacement, the upper ends of the flap bodies (3a) (3a) come into contact with the peripheral surface (11) of the opening (10).

By the abutting of the flap bodies (3a) (3a), the main body (2a) is fixed to the opening (10), that is, the countertop (1). After this fixing, the soup saucer (2b) is placed on the main body (2a), and further, the gotoku (24) is placed on the soup saucer (2b). This completes the installation of the drop-in stove (K).

This device has the following effects. ． The amount of outward displacement of the upper end of the flap body (3a) (3a) is adjusted by tightening each of the above bolts (4) (4), so that various openings (10 ), The drop-in stove (K) can be fixed. ． Since the bolts (4) are located below the upper end of each flap body (3a) that comes into contact with the peripheral surface (11), the position where the bolt and the opening peripheral surface are in contact with each other in the vertical direction. Case body compared to the conventional one where the bolts are located at the same height
The amount of protrusion of the bolt (4) to the upper area inside the (2) is suppressed. Therefore, even if the juice saucer (2b) is deep, the inclined wall (22) does not hit the bolt (4), and the juice saucer (2b) is the main part.
Can be attached to (2a). This effect becomes remarkable especially when the wall thickness of the countertop (1) is small.

.. Since the outward displacement amount of the upper end portion is large relative to the outward movement amount of the bolt (4), the bolt (4) can be shorter than the conventional one. In this respect as well, the amount of protrusion of the bolt (4) to the upper area inside is suppressed. ． Since the lower end of the flap body (3a) is rotatably connected to the side wall (21a), the lower end is fixed to the side wall (21a) and the flap body (3a) is elastic. The operation force of the bolt (4) is smaller than that of the one displaced by deformation or plastic deformation.

Therefore, the structure for the rotation is simpler than that of the shaft support type. ． Since the protrusions (36) and (36) prevent the flap body (3a) from being displaced more than a predetermined amount outwardly, the flap body (3a) hangs downward due to the rotation or a bent piece. This prevents the inconvenience that the part (33) comes out of the elongated hole (210) and the flap body (3a) comes off from the side wall part (21a). Therefore, the work of mounting the drop-in stove (K) is facilitated.

.. Since the flap body (3a) is maintained along the side wall portion (21a) by the protrusions (35) and (35), the mounting operation is further facilitated. Further, the flap body (3a) does not get in the way of packing the drop-in stove (K) at the time of shipping and the like, and the packing work and the like are facilitated.
