It is composed of a mating protrusion 18.

  The engagement protrusion 18 is formed by forming a long kerf on the upper and lower sides of the side piece 17 and projecting the lower part of the kerf forward by pressing. For this reason, the upper end surface of the engagement protrusion 18 is a horizontal surface constituted by a cut surface when the kerf is formed. The protruding base end portions on the lower side and both sides excluding the upper edge of the engaging protrusion 18 are connected to the side piece portion 17.

  The insertion portion 16 is constituted by the side piece portion 17 and the oblique piece portion 51. A portion from the lower end portion of the side piece portion 17 to the upper end of the oblique piece portion 51 in the insertion portion 16 is a narrow portion 33 having a narrower left and right width than the upper portion of the side piece portion 17. Moreover, by this, the upper both side edge part of the side piece part 17 becomes the stopper part 34 which protruded on the outer side of the left-right direction rather than the narrow part 33, and the lower end surface of each stopper part 34 is a horizontal surface.

  The connecting portion 26 includes a connecting piece 20 that protrudes obliquely upward from the upper end of the side piece 17 and a vertical piece 21 that protrudes vertically upward from the connecting piece 20.

  The engaged portion 14 includes a horizontal horizontal piece portion 22 that protrudes rearward from the upper end of the vertical piece portion 21, a rising piece portion 23 that rises upward from the rear end of the horizontal piece portion 22, The inclined piece portion 24 protrudes obliquely upward from the upper end of the piece portion 23 and the front protruding piece portion 25 protrudes forward from the upper end of the inclined piece portion 24. The upper surface of the inclined piece portion 24 is an abutting surface 27 that faces obliquely upward and is inclined to the rear side in the protruding direction of the engaged portion 14.

  As shown in FIG. 5, on the rear surface side of the vertical piece 10 b of the main body case 6, an insertion hole 29 for inserting the insertion portion 16 from above and an engaged hole portion 30 for engaging the engagement protrusion 18. Is formed.

  The engaged hole portion 30 has a portion 44 between the two kerfs formed on the vertical piece 10b so as to be separated from each other in the vertical direction, and protrudes rearward by pressing, and is formed by a hole formed between the two kerfs. Composed. Therefore, the upper and lower edge surfaces of the engaged hole portion 30 are horizontal surfaces constituted by the cut surfaces when the kerf is formed.

  The insertion hole 29 is composed of a hole opened up and down surrounded by a portion 44 between the upper and lower kerfs protruding by the press working. Accordingly, the engaged hole 30 is positioned in front of the insertion hole 29.

  On both the left and right sides of the upper portion of the engaged hole portion 30 in the vertical piece 10b, a restricting portion 31 protruding rearward is formed. Between the pair of restricting portions 31, the gap in the left-right direction is substantially the same as the left-right width of the upper portion of the side piece portion 17, and a gap that allows passage through the insertion portion 16 is formed.

  Moreover, the contact part 32 which protrudes back is formed in the right-and-left both sides of the downward part of the to-be-engaged hole part 30 in the vertical piece 10b. Between the pair of contact portions 32, a gap is formed in which the gap in the left-right direction is smaller than the left-right width of the upper portion of the side piece portion 17 and slightly larger than the left-right width of the narrow portion 33, The narrow portion 33 can be passed. Further, the upper portion of the side piece 17 cannot pass through this gap. In addition, each contact part 32 and each above-mentioned control part 31 cut and raise a part of vertical piece 10b.

  In order to attach each engaged body 12 to the front frame 10, the insertion portion 16 is disposed between the two restriction portions 31, and from here, the insertion portion 16 is moved downward and inserted into the insertion hole 29. At this time, since the insertion portion 16 is restricted from moving in the left-right direction by the pair of restriction portions 31, the insertion portion 16 can be smoothly inserted into the insertion hole 29.

  The insertion portion 16 has a lower end projecting downward from the insertion hole 29, the lower end surfaces of the stopper portions 34 on both sides contact the upper surface of the corresponding contact portion 32, and the engagement protrusion 18 corresponds to the engaged hole portion 30. It is inserted until it moves to the position to be engaged, and by inserting in this way, the engagement protrusion 18 protruding forward is engaged with the engaged hole 30.

  In this attached state, the insertion portion 16 is inserted into the insertion hole 29, the upper portion of the side piece portion 17 is located between the pair of restricting portions 31, and the width between the pair of contact portions 32 is wide. The lower end portion of the narrowed strip portion 17 is positioned, and the lateral movement of the engaged body 12 is restricted. Moreover, each stopper part 34 contacts the contact part 32, and a downward movement is controlled.

  Further, the slant piece 51 of the insertion portion 16 is in elastic contact with the front surface of the portion 44 constituting the rear wall portion of the insertion hole 29, and the upper end surface of the engagement protrusion 18 is the horizontal upper edge of the engagement hole portion 30. By engaging with the surface, the upward movement is restricted, whereby the attachment portion 13 of each engaged body 12 is firmly fixed to the front frame 10.

  Here, since the upper end surface of the engagement protrusion 18 is formed by a cut surface when the kerf is formed, the engagement protrusion 18 is firmly engaged with the lower surface of the upper edge portion of the engaged hole portion 30 which is also formed by a horizontal cut surface. Can be made. Therefore, it is possible to reliably prevent the insertion portion 16 from coming out of the insertion hole 29 upward.

  On the other hand, the engaging body 11 is made of a bent metal plate and is attached to both sides of the lower surface of the front portion of the top plate 37.

  Each engagement body 11 includes a top plate side fixing portion 45 attached along the lower surface of the top plate 37 and a main body side fixing portion 19 protruding downward from the top plate side fixing portion 45.

  The main body side fixing portion 19 protrudes downward from a position slightly behind the front end of the top plate 3. The main body side fixing portion 19 includes a hanging piece portion 46 parallel to the left and right direction that hangs down from the rear end of the top plate side fixing portion 45, and a side edge piece that protrudes rearward from the both side edges and the lower edge of the hanging piece portion 46. It comprises a portion 47 and a lower edge piece 48.

  An engagement hole portion 49 having a horizontal lower edge surface is formed in the upper portion of the hanging piece portion 46. In this example, a portion located below the engagement hole portion 49 of the main body side fixing portion 19 is engaged. The joint 15 is used. Further, the lower ends of the side edge piece portions 47 on both sides are connected to both ends of the lower edge piece portion 48, whereby the main body side fixing portion 19 is reinforced, and the engaging portion 15 of the engaging body 11 is connected to the engaged body 12. It is hard to be deformed.

  Next, a method for attaching the top plate 3 to the furnace body 2 will be described.

  When the top plate 3 is attached to the furnace body 2 suspended from the counter 4, first, the top plate 3 is made substantially horizontal as shown in FIG. 8, and the positions of the gas burners 7 corresponding to the respective burner holes 35 are set. Combine them and place them directly above the mounting position. Thereby, the engaging part 15 of the engaging body 11 is positioned above the contact surface 27 of the engaged part 14 of the engaged body 12.

  From here, the top plate 3 is moved substantially vertically downward while maintaining the horizontal state while aligning the gas burners 7 corresponding to the respective burner holes 35 to be inserted, and the top plate 3 is moved to the flange of the furnace body 2. As shown in FIG. 3, the peripheral portion of the plate frame 36 of the top plate 3 is placed on the counter 4 via the sealing material 39. Thereby, the engaging body 11 is engaged with the engaged body 12 as follows.

  When the top plate 3 moves substantially vertically downward, first, the lower end portion of the engaging portion 15 of the engaging body 11 that moves substantially vertically downward together with the top plate 3 is the contact surface of the engaged portion 14 of the engaged body 12. 27 abuts.

  When the top plate 3 is further moved substantially vertically downward and the contact surface 27 is pressed downward by the lower end portion of the engaging portion 15, the engaged body 12 is elastically deformed and the engaged portion 14 is projected. The engaging portion 15 moves downward along the contact surface 27 of the engaged body 12 and the rear surface of the rising piece portion 23.

  Further, when the top plate 3 is moved substantially vertically downward and the engaging body 11 is moved downward, the engaging portion 15 gets over the engaged portion 14 and the engaging hole portion 49 is in a position corresponding to the engaged portion 14. Accordingly, the engaged body 12 is elastically restored, the engaged portion 14 moves to the rear side, and the engaged portion 14 is fitted into the engaging hole portion 49.

  In this attached state, the engaging portion 15 (the lower edge portion of the engaging hole portion 49) is engaged with the lower surface front end portion of the engaged portion 14 (the lower surface front end portion of the horizontal piece portion 22). As a result, the engaging body 11 is engaged with the engaged body 12 so as not to move upward and left and right.

  Further, when the engaging portion 15 is engaged with the engaged portion 14 as described above, the top plate 3 is placed on the flange portion 9 of the furnace body 2, and the plate frame 36 of the top plate 3. Is placed on the upper surface of the counter 4 via the sealing material 39, and the top plate 3 cannot move downward.

  In this state, the rear portion of the top plate 3 is screwed to the furnace body 2 with the screws, whereby the attachment of the top plate 3 to the furnace body 2 is completed.

  As described above, the gas furnace 1 of the present example described above is an engagement body in which, when the top plate 3 is attached to the furnace body 2, the top plate 3 is moved substantially vertically downward and placed on the furnace body 2. 11 engaging portions 15 are brought into contact with the engaged portions 14 of the engaged bodies 12 and the engaged portions 15 are pushed downward by the engaging portions 15 to elastically deform the engaged bodies 12 to be engaged. The portion 15 can get over the engaged portion 14 and can be engaged with the lower surface front end portion of the engaged portion 14. Therefore, in a state where the top plate 3 is attached to the furnace body 2, the engaging portion 15 can be brought into contact with the lower surface of the engaged portion 14 and the front portion of the top plate 3 can be reliably prevented from being lifted.

  Further, by aligning the position of each burner hole 35 of the top plate 3 with the corresponding gas burner 7, the positions of the engaging portion 15 of the engaging body 11 and the engaged portion 14 of the engaged body 12 can be aligned. The engaging body 11 provided on the lower surface of the top plate 3 that is difficult to visually recognize can be easily engaged with the engaged body 12.

  Further, the top plate 3 of the present example is such that the engaging portion 15 of the engaging body 11 provided on the lower surface of the front portion of the top plate 3 protrudes rearward from the upper portion of the engaged body 12 to the lower surface of the engaged portion 14. In addition to engaging with the front end portion, the rear portion of the top plate 3 is detachably attached to the furnace main body 2 by the screws, and is installed on the furnace main body 2 in this state.

  Therefore, even when an upward force is applied to the front portion of the top plate 3 with the top plate 3 installed on the furnace body 2 as described above, the engaging portion located below the front portion of the top plate 3. 15 presses the corner portion formed by the horizontal piece portion 22 and the vertical piece portion 21 of the engaged body 12 engaged with the rear portion of the top plate 3 attached with screws toward a substantially vertical upper side. For this reason, it is difficult to disengage the engaging portion 15, and it is possible to reliably prevent the front portion of the top plate 3 from being lifted.

  Further, the top plate 3 may be removed from the furnace main body 2 during maintenance or the like. In this case, the screws are removed, and the engagement between the engaging body 11 and the engaged body 12 is released. By removing the top plate 3 as described below, the engagement between the engaging body 11 and the engaged body 12 can be easily released.

  That is, in order to remove the top plate 3, first, the screws are removed so that the rear portion of the top plate 3 can be moved, and then the sealing member is placed on the counter 4 while the engaging body 11 is engaged with the engaged body 12. The rear part of the top plate 3 is lifted with the front end portion of the top plate 3 placed via 39 as a fulcrum.

  If it does in this way, the horizontal piece part 22 will be pushed up back diagonally upward by the engaging part 15, the to-be-engaged body 12 will elastically deform, and the to-be-engaged part 14 will use the upper end part of the vertical piece part 21 as a fulcrum. Then, the engaging portion 15 is disengaged from the engaged portion 14.

  Here, as the engaged body 12 bends forward, the engaging position of the engaging portion 15 with respect to the engaged portion 14 gradually moves from the front end portion of the lateral piece portion 22 to the rear side. For this reason, the moment about the upper end of the vertical piece 21 applied from the engaging portion 15 to the engaged portion 14 gradually increases. Therefore, as described above, the engagement between the engaging portion 15 and the engaged portion 14 can be easily released by lifting the rear portion of the top plate 3.

  Moreover, in the state which attached the top plate 3 to the furnace main body 2 as mentioned above, as shown in FIG. 3, the front end part lower surface of the top plate 3 becomes substantially flush with the upper surface of the counter 4 of a kitchen stand. For this reason, as in this example, the front end portion of the top plate 3 is placed on the counter 4 via the sealing material 39, and the broth or the like enters between the front end portion of the top plate 3 and the upper surface of the counter 4. This can be reliably prevented.

  In this example, the engaged portion 14 is pressed against the engaging portion 15 by moving the top plate 3 substantially vertically downward while the engaging portion 15 is in contact with the engaged portion 14. Thus, the engaged body 12 is elastically deformed, and the engaging portion 15 gets over the engaged portion 14 and engages the lower surface of the engaged portion 14. When the top plate 3 is moved substantially vertically downward while being in contact with the upper side, the engaging body 11 is elastically deformed, and the engaging portion 15 gets over the engaged portion 14 and the lower surface of the engaged portion 14. It does not matter even if it engages.

  Furthermore, although the engaging body 11 is provided in the lower surface front part of the top plate 3, it may be provided in the rear part or side part in the lower surface of the top plate 3.
