  However, in the positioning structure of the conventional virtues (5), the fixing protrusion (52) is configured to protrude on the back side of the virtues (5), so the fixing protrusion (52) is formed in the through hole (45). It is not possible to actually confirm the state of being inserted into the eye. In order to facilitate the insertion of the fixing protrusion (52) into the through hole (45), the size of the through hole (45) is such that the fixing protrusion (52) is inserted into a loosely fitted state. It must be set large. Then, for example, when an external impact such as being pressed from above is applied to the outer end of one virtuosity claw (51) as shown by the arrow in FIG. 6, the fixing projection (52) Since it is only inserted into the hole (45) in a loosely fitted state from above, the virtuosity frame (50) is inclined with the lower end of the pressurized virtuosity claw (51) as a fulcrum or loosely. There was an inconvenience.

  In particular, in recent years, to make the top plate look clearer, the width of the column that supports the Gotoku nail (51) is narrowed in design, or the outer end of the Gotoku nail (51) protrudes outward longer than the above column. There is a tendency to let it. From this, when an external impact is applied to the outer end of the virtuosity claw (51), the virtues (5) are more easily inclined, and the fixing protrusion (52) may come out of the through hole (45). is there.

  Also, if the fixing protrusion (52) of the virtuosity claw (51) is used without being securely inserted into the through hole (45), the height of the virtuosity claw (51) from the burner cannot be kept constant. , The thermal efficiency becomes worse. Further, when the center of the virtuosity frame (50) is displaced from the center of the opening (30), the inner side of the virtuosity frame (50) hits the flame of the burner, resulting in poor combustion, ) Is discolored by heat.

  The present invention is the five virtues that are placed on the top plate that covers the upper surface of the stove body in which the heating source is accommodated and that has openings at each location corresponding to the heating source, In the "5 virtues positioning structure consisting of a virtuosity frame disposed along the periphery of the opening and a plurality of virtues claws fixed to the upper surface of the virtues frame", the virtues can be easily positioned on the top plate. Further, it is an object of the present invention to maintain a stable positioning posture without rattling the virtues even when an external impact such as being pressed from above is applied to a part of the virtues.

(1) The five virtue positioning structure of the invention according to claim 1 is as follows: “A plurality of locking pins project at predetermined distances on the top surface of the top plate along the periphery of the opening;
The five-virtual frame is formed of a thin annular plate and is formed with a locking hole through which a tip of the locking pin can be inserted at each position corresponding to the locking pin.
With the leading end of the locking pin inserted into the locking hole, the locking pin is prevented from slipping into the locking hole by rotating the virtually frame in the circumferential direction or pushing it downward. A locking means is provided at the tip of the locking pin so as to be locked in the state.
The above means operates as follows.
The five virtues are positioned above the opening of the top plate so that the locking holes provided in the five virtues frame of the virtues face each locking pin provided so as to protrude upward around the opening of the top plate. The tip of the locking pin is inserted through the locking hole. From this state, by moving the virtually frame in the circumferential direction or by pushing it downward, the detachable means provided at the tip of the locking pin causes the virtually frame to be It is positioned and fixed in a retaining state with respect to the set pin.

(2) As shown in claim 2, “the locking pin and the locking hole are provided one by one at positions facing each other through the opening”, with respect to the center of virtues Since it will be fixed at two points at the opposite position, it will be installed in a stable state, and even if external pressure is applied to the engaging part side of the locking pin and the locking hole, the virtues will rattle. In addition, even if the position moved in the circumferential direction by about 90 degrees from the engaging portion is pressurized, the virtues will not tilt.

(3) In claim 1 or 2, "The top plate is made of glass, and a protective ring for preventing cracking is attached to the periphery of the opening, and the locking pin is a part of the protective ring. In the case of `` projecting on the upper surface of the upper ring that protects the upper surface of the peripheral edge of the opening '', the locking pin projects even on the peripheral edge of the glass top plate through the upper ring of the protective ring. Can be installed. In this case, unlike the conventional one, it is not necessary to project the inner peripheral end of the upper ring into the opening in order to form a hole for inserting the fixing protrusion of the virtues.

(4) In any one of claims 1 to 3, “the locking pin includes a small-diameter shaft portion and a large-diameter locking portion provided at a tip thereof,
The locking hole is formed with a deformed long hole-shaped locking hole formed by continuously connecting a large-diameter hole portion and a small-diameter hole portion in the circumferential direction,
The large-diameter locking portion of the locking pin is set to a size that can be inserted into the large-diameter hole portion of the locking hole, and the small-diameter hole portion is large enough to fit the shaft portion. Is set to
In the state where the five virtue frames are placed on the top plate, the length of the shaft portion is set so that the large-diameter locking portion protrudes upward from the locking hole. A locking hole having a deformed elongated hole is opposed to the locking pin, and the large-diameter locking portion of the locking pin is inserted into the large-diameter hole of the locking hole. In this state, the five virtue frames are placed on the top plate, and at this time, a dimensional relationship is set such that a large-diameter locking portion of a locking pin protrudes upward from the locking hole. In this insertion state, the shaft portion corresponds to the locking hole, and the virtually frame is rotated in the circumferential direction to the side where the small diameter hole portion is formed. Since the small-diameter hole portion is set to a size that allows the shaft portion to be inserted, the shaft portion is forcibly inserted into the small-diameter hole portion, and the five virtue frames are prevented from coming off from the locking pin. Positioned and fixed to the state.

(5) In any one of claims 1 to 3, "the retaining means is formed by combining a plurality of substantially letter-shaped leaf springs outwardly to form a minimum diameter portion at the tip, and The locking projection has a shape with a maximum diameter formed on the part,
In the natural state, the locking projection is set so that the maximum diameter portion is larger than the locking hole and is elastically deformable so as to be able to be inserted through the locking hole. Only by making the locking projection correspond to the hole, only the tip of the locking projection penetrates the locking hole. From this state, the plate spring constituting the locking projection is elastically deformed by forcibly pushing down the five virtue frames, and the locking projection is inserted through the locking hole. After the insertion, the locking projection elastically returns to the initial state, and the maximum diameter portion of the locking projection becomes larger in diameter than the locking hole. Become.

  According to the invention which concerns on Claim 1, after making the latching hole provided in the virtuality frame correspond to each of the some latching pin provided in the opening periphery of the top plate, the virtuosity frame is made into a predetermined direction. By rotating or forcing down downward, the retaining pin provided at the tip of the locking pin is fixed in a retaining state with respect to the retaining hole. The frame is fixed to the peripheral edge of the opening of the top plate in a circumferentially positioned state and a retaining state. Therefore, for example, even if a force is inadvertently applied to one outer end portion of the five virtue claws, the five virtues do not rattle, and a stable mounting state can always be maintained. Since the state where the locking pin is inserted into the locking hole can be visually confirmed, the positioning work of the virtues is easy to perform, and there is no inconvenience that the virtues are installed in the wrong posture and used as they are.

According to the second aspect of the present invention, since the locking pin and the locking hole are provided only at two positions facing each other through the opening, the virtues can be installed in a stable state, and the locking pin And positioning and formation of a locking hole become easy.
According to the invention which concerns on Claim 3, it becomes employable also with a glass-made top plate by forming a locking pin in the upper surface of a protection ring. In this case, since it is not necessary to project the inner peripheral end of the upper ring into the opening, it is possible to keep the opening of the glass top plate to the minimum necessary, and ensure a sufficient distance between the openings. be able to. In other words, since the glass area can be increased, the strength of the glass top plate can be improved.

  According to the invention which concerns on Claim 4, the large diameter hole part of the deformation | transformation long-hole shaped locking hole provided in the five virtue frame is inserted in each of the some locking pin provided in the opening periphery of the top plate correspondingly. Then, the shaft portion is fixed to the small diameter hole portion of the deformed long hole in a retaining state by rotating the five virtue frame to the side where the small diameter hole portion is formed. Moreover, since the large diameter latching part should just be larger diameter than a small diameter hole part, it is possible to set the height of a large diameter latching part low. Therefore, the large-diameter locking portion that protrudes upward from the virtuosity frame can be configured so as to be as inconspicuous as possible even if it protrudes above the virtuosity frame, for example, has a substantially flat shape. The beauty of the top plate is not impaired.

  According to the fifth aspect of the present invention, each of the plurality of locking pins provided on the opening peripheral edge of the top plate is associated with the locking hole provided in the five-virtual frame, and the locking hole is provided with the locking pin. After inserting the tip of the locking projection provided at the tip, the virtually frame can be fixed in a positioning state with respect to the top plate by simply pushing down the virtuosity frame. The engagement between the locking projection and the locking hole is not inadvertently released.
