Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a stove to a worktop when a stove such as a gas stove is fitted into an opening of a worktop such as a counter in a system kitchen or the like and built in.

[0002]

2. Description of the Related Art Conventionally, when a stove 1 such as a gas stove is fitted and mounted in an opening 3 of a worktop 2 such as a counter, as shown in FIG. Are screwed together, and the tip of the fixing screw 5 is fixed by abutting on the side surface 3 a of the opening 3. In FIG. 7, reference numeral 6 denotes a top plate.

[0003]

However, in the case of the fixed structure as shown in FIG. 7, the outer peripheral surface of the top plate 6 is close to the inner surface of the casing 4 due to the depth of the top plate 6 and the like. 6 cannot be adopted when the gap between the outer peripheral surface of the casing 6 and the inner surface of the casing 4 is small. That is, as shown in FIG. 8, the gap between the outer peripheral surface of the top plate 6 and the side surface 3a of the opening 3 is small, and there is no space for the fixing screw 5 to be accommodated. In FIG.
Is a gap between the outer peripheral surface of the top plate 6 and the side surface 3a of the opening 3, b
Is the length of the fixing screw 5, and for b> a, the fixing screw 5
Does not enter. Further, simply using a short fixing screw 5 so as to fit in the space can be achieved by opening 3 as shown in FIG.
Cannot be fixed because it does not reach the side surface 3a. In FIG. 9, the symbol c indicates the outer surface of the casing 4 and the opening
Is the maximum value of the gap between the fixing screw 5 and the side surface 3a, and d is the length under the neck of the fixing screw 5, and cannot be fixed unless d> c. Further, as shown in FIG. 10, when the position of the fixing screw 5 is simply changed downward to a position where the top plate 6 does not contact the fixing screw 5, the position of the fixing screw 5 becomes lower than the lower surface of the worktop 2. Since the tip of the fixing screw 5 does not contact the side surface 3a of the opening 3, the fixing cannot be performed.

As a solution to this problem, there is one as shown in FIG. Plate-shaped fixing members 7 are arranged on outer surfaces on both sides of the casing 4, and the fixing members 7 are rotatably mounted by inserting locking claws 8 at lower ends of the fixing members 7 into the casing 4. That is, the portion where the locking claw 8 is inserted into the casing 4 is rotated about the fulcrum C.
A fixing screw 5 is screwed into the casing 4 from the inside of the casing 4 at a position above the fulcrum C. According to the principle of leverage, the fixing metal 7 is pushed with the fixing screw 5 at a short distance (action point A) from the fulcrum C, and the side surface 3a of the opening 3 is pressed with the fixing metal 6 at a long distance (action point B) from the fulcrum C and fixed. It is supposed to. However, in such an example, when the stove 1 installed on the worktop 2 is removed, simply by loosening the fixing screw 5, the fixing bracket 6 can move freely between the casing 4 and the side surface 3 a of the opening 3. In addition, there is a possibility that the metal fixture 6 is caught on the side surface 3a and the stove 1 cannot be removed from the worktop 2.

[0005] Then, what is shown in FIG. As shown in the figure, a knob 9 protruding from the upper end of the fixing bracket 7 is inserted into a hole of the casing 4. When the knob 9 is pulled inside the casing 4, the hole of the casing 4 is pulled. A convex portion 9 a that locks to the portion is provided at the base of the knob 9. In this way, the fixture 7 can be fixed to the casing 4 by holding the knob 9 and pulling the fixture 7 inward, so that the stove 1 can be removed smoothly. However, this structure requires two operations, that is, the operation of loosening the fixing screw 5 and the operation of fixing the fixing fitting 7 to the casing 4, and thus the workability is not good as compared with the conventional fixing method of the build-in stove. There's a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and has a structure for fixing a build-in stove to a worktop, which can be easily attached to a stove having a narrow fixing portion and can be easily removed. The task is to provide.

[0007]

In order to solve the above-mentioned problems, a structure for fixing a build-in stove to a worktop according to the present invention is such that a casing 4 of a stove 1 is fitted into an opening 3 provided in a worktop 2 so that the casing 4 is attached. In the fixture to be fixed to the worktop 2, a fixture 7 swinging between the outer surface of the casing 4 and the side surface 3 a of the opening 3 is rotatably mounted on the casing 4, and the fixture 7 is attached to the outer surface of the casing 4. A spring member 10 that urges to rotate is provided, and a fixing screw 5 whose tip abuts on a fixing metal 7 from the inner surface side of the casing 4 is screwed into the casing 4 and fixed against the spring force of the spring member 10. It is characterized in that the fixing metal 7 is pushed by screwing the screw 5 so that the tip of the fixing metal 7 abuts on the side surface 3 a of the opening 3 and is fixed. The stove 1 is fitted into the opening 3 of the worktop 2 in a state in which the fixing screw 5 is retracted and the fixing metal 7 is in contact with the outer surface of the casing 4 by the spring force of the spring member 10, and the fixing screw 5 is screwed to advance the spring. The stove 1 can be attached to the worktop 2 by rotating the fixture 7 against the force and pressing the tip of the fixture 7 against the side surface 3 a of the opening 3. By retracting the fixing screw 5 so as to loosen, the fixing metal 7 is separated from the side surface 3a of the opening 3 by the spring force of the spring member 10, and the stove 1 can be removed by pulling the stove 1 upward. Since the stove 1 can be fixed as described above, the stove 1 can be fixed even with the stove 1 having a narrow fixing portion. Further, since the fixing bracket 7 can be rotated by the leverage principle, the screwing amount of the fixing screw 5 can be reduced, and the screwing work of the fixing screw 5 when the stove 1 is fixed can be shortened. Also, when the stove 1 is fitted into the opening 3 of the worktop 2 when the stove 1 is attached, the fixing metal 7 is not in the way because the fixing metal 7 is in contact with the casing 4 by the spring force of the spring member 10. When the stove 1 is to be removed from the worktop 2 for replacement or inspection of the stove 1, if the fixing screw 5 is loosened, the fixing metal 7 returns by the spring force of the spring member 10 and the outer surface of the casing 4. Therefore, the stove 1 can be removed smoothly without the fixture 7 being caught on the side surface 3a of the opening 3 of the worktop 2.

The spring member 10 is formed as a band-shaped leaf spring 10a.
It is also preferable that one end of the leaf spring 10a is integrally fixed to the distal end of the fixture 7, and the other end of the leaf spring 10a is in contact with the outer surface of the casing 4. In this case, the structure of the spring member 10 can be simplified, the assemblability can be improved, and the space can be saved.
