Description

本発明は、平板状の天板本体と、天板本体の上面の前縁部、左右両側縁部及び後縁部を覆う前辺部、左右両側辺部及び後辺部を有する額縁状の板金製外枠とを備えるコンロ用天板に関する。 The present invention is a frame-shaped sheet metal having a flat top plate body, a front edge portion covering both the front edge portion, the left and right side edge portions and the rear edge portion of the top surface of the top plate body, the left and right side portions and the rear edge portion. A top plate for a stove provided with an outer frame.

この種のコンロ用天板であって、外枠後辺部の天板本体よりも後方に位置する部分に、コンロに設けられるグリルの排気筒が臨む排気口を開設したものでは、外枠後辺部が排気筒からの熱影響で上方に反るように変形し、外枠後辺部と天板主体との間に隙間を生じてしまうことがある。 If this type of stove top plate has an exhaust opening that faces the exhaust pipe of the grill provided on the stove in the rear part of the top plate body on the rear side of the outer frame, The side part may be deformed so as to warp upward due to the heat from the exhaust tube, and a gap may be formed between the rear side part of the outer frame and the top plate main body.

かかる不具合を防止するため、従来、外枠後辺部の下面にブラケットを取付け、このブラケットに、天板主体の後部下面に当接する押え板を下方からネジ止めしたものが知られている（例えば、特許文献１参照）。これによれば、押え板とブラケットとを介して外枠後辺部に下方への押し付け力が作用し、外枠後辺部が上方に反るように変形することを防止できる。 In order to prevent such inconvenience, conventionally, a bracket is attached to the lower surface of the rear side of the outer frame, and a presser plate that contacts the rear lower surface of the top plate main body is screwed to the bracket from below (for example, , See Patent Document 1). According to this, it is possible to prevent a downward pressing force from acting on the rear side of the outer frame via the presser plate and the bracket, and to deform the outer frame rear side so as to warp upward.

ここで、外枠後辺部の下面に押え板を直接ネジ止めすることも考えられるが、これではネジが外枠後辺部の上面に露出して体裁を損なう。そこで、上記従来例では、外枠後辺部の下面に取付けたブラケットに押え板をネジ止めして、ネジが外枠後辺部の上面に露出しないようにしているのである。然し、これでは、ブラケットの分だけ部品点数が増加して、コストアップを招いてしまう。 Here, it is conceivable that the presser plate is directly screwed to the lower surface of the rear side of the outer frame. However, in this case, the screw is exposed to the upper surface of the rear side of the outer frame and the appearance is damaged. Therefore, in the above conventional example, the holding plate is screwed to a bracket attached to the lower surface of the outer frame rear side portion so that the screw is not exposed to the upper surface of the outer frame rear side portion. However, this increases the number of parts by the amount of the bracket, leading to an increase in cost.

本発明は、以上の点に鑑み、外枠後辺部が上方に反るように変形することを防止して、且つ、コストダウンを図ることができるようにしたコンロ用天板を提供することをその課題としている。 In view of the above, the present invention provides a stove top plate that prevents the rear side of the outer frame from being deformed so as to warp upward and can reduce the cost. Is the issue.

上記課題を解決するために、本発明は、平板状の天板本体と、天板本体の上面の前縁部、左右両側縁部及び後縁部を覆う前辺部、左右両側辺部及び後辺部を有する額縁状の板金製外枠とを備えるコンロ用天板であって、外枠後辺部の天板本体よりも後方に位置する部分に、コンロに組み込まれるグリルの排気筒が臨む排気口が開設されるものにおいて、外枠後辺部の排気口の前縁部上面に当接する上片部と、天板本体の後部下面に当接する下片部と、排気口内で上片部と下片部とを連結する後端の折返し部とを有するバネ材から成る係止具を備え、当該係止具により天板本体と外枠後辺部とが挟持されることを特徴とする。 In order to solve the above-described problems, the present invention provides a flat top plate body, a front edge portion covering the front edge portion, the left and right side edge portions and the rear edge portion of the top surface of the top plate body, the left and right side portions and the rear portion. A stove top plate having a frame-shaped sheet metal outer frame having a side part, and an exhaust pipe of a grill incorporated in the stove faces a portion located behind the top plate body on the rear side part of the outer frame. In the case where the exhaust port is opened, the upper piece portion that contacts the upper surface of the front edge of the exhaust port at the rear side of the outer frame, the lower piece portion that contacts the lower surface of the rear portion of the top plate body, and the upper piece portion in the exhaust port And a lower end folded portion that connects the lower piece portion, and the top plate body and the outer frame rear side portion are clamped by the locking device. .

本発明によれば、係止具により天板本体と外枠後辺部とが挟持されるため、天板本体に対し外枠後辺部が上方に反るように変形することが防止され、外枠後辺部と天板本体との間に隙間は生じない。そして、係止具を付加するだけであるため、ブラケットと押え板とが必要になる上記従来例のものに比し、部品点数を削減してコストダウンを図ることができる。尚、一般的に、外枠後辺部には、排気口を覆う排気ガードが載置されるため、係止具は排気ガードで目隠しされて外観に現れず、体裁を損なうことはない。 According to the present invention, the top plate body and the outer frame rear side portion are sandwiched by the locking tool, so that the outer frame rear side portion is prevented from being deformed so as to warp upward with respect to the top plate main body, There is no gap between the rear side of the outer frame and the top plate body. Further, since only the locking tool is added, the number of parts can be reduced and the cost can be reduced as compared with the conventional example in which the bracket and the pressing plate are required. In general, an exhaust guard that covers the exhaust port is placed on the rear side of the outer frame. Therefore, the locking tool is hidden by the exhaust guard so that it does not appear in the appearance and the appearance is not impaired.

また、本発明においては、外枠後辺部に、排気口の前縁で下方に折返された折返し縁部が設けられ、係止具の下片部に、折返し縁部の前端に係合して係止具を抜け止めする爪部が設けられることが望ましい。更に、係止具が排気筒への折返し部の当接で抜け止めされるようにしてもよい。これにより、係止具が脱落して、外枠後辺部の変形防止の効果が得られなくなることを回避できる。 In the present invention, the outer frame rear side portion is provided with a folded edge portion that is folded downward at the front edge of the exhaust port, and the lower piece portion of the locking tool engages with the front end of the folded edge portion. It is desirable to provide a claw portion for preventing the locking tool from coming off. Further, the locking tool may be prevented from coming off when the folded portion comes into contact with the exhaust pipe. Thereby, it can avoid that a latching tool falls and the effect of a deformation | transformation prevention of an outer frame rear side part cannot be acquired.

図１は、コンロ本体１と、コンロ本体１の上面を覆う本発明の実施形態のコンロ用天板２とを備えるコンロを示している。コンロ本体１には、コンロ用天板２の左右２箇所に介設したバーナ用開口を通して天板２上に露出する左右２個のコンロバーナ３，３と、コンロ本体１の横方向中央部のグリル４とが設けられている。 FIG. 1 shows a stove including a stove body 1 and a stove top 2 according to an embodiment of the present invention that covers the top surface of the stove body 1. The stove body 1 includes two left and right stove burners 3 and 3 that are exposed on the top plate 2 through the burner openings provided in the left and right portions of the stove top plate 2, and the horizontal central portion of the stove body 1. A grill 4 is provided.

図２乃至図４も参照して、コンロ用天板２は、金属厚板やガラス板から成る天板本体２１と、天板本体２１の上面の前縁部、左右両側縁部及び後縁部を覆う前辺部２２１、左右両側辺部２２２，２２２及び後辺部２２３を有する額縁状のプレス成形された板金製外枠２２とを備えている。天板本体２１の前縁部と左右両側縁部は、図示しないが、コンロ本体１の前面板部と左右両側板部の上端に形成した内曲げフランジの複数個所に取付けたパッキンに着座している。また、外枠２２の前辺部２２１、左右両側辺部２２２，２２２及び後辺部２２３は、天板本体２１の上面の前縁部、左右両側縁部及び後縁部にコーキング剤２２４（図３参照）で接着されている。 2 to 4, the stove top plate 2 includes a top plate body 21 made of a thick metal plate or glass plate, a front edge portion on the top surface of the top plate body 21, left and right side edge portions, and a rear edge portion. A frame-shaped press-molded sheet metal outer frame 22 having a front side part 221, a left and right side parts 222, 222, and a rear side part 223. Although not shown, the front edge and the left and right side edges of the top plate body 21 are seated on packings attached to a plurality of internal bending flanges formed at the upper ends of the front plate and the left and right side plates of the stove body 1. Yes. Further, the front side 221, the left and right side parts 222, 222 and the rear side part 223 of the outer frame 22 are caulking agent 224 (see FIG. 3)).

ここで、外枠後辺部２２３は天板本体２１の後方に幅広く張出している。そして、外枠後辺部２２３の天板本体２２１よりも後方に位置する部分に、グリル４の排気筒４１が臨む排気口２２５が開設されている。また、外枠後辺部２２３上に、排気口２２５を覆う網状の排気ガード２３を載置している。 Here, the outer frame rear side portion 223 extends widely behind the top plate body 21. And the exhaust port 225 which the exhaust pipe 41 of the grille 4 faces is opened in the part located behind the top plate main body 221 of the outer frame rear side part 223. In addition, a net-like exhaust guard 23 that covers the exhaust port 225 is placed on the rear side 223 of the outer frame.

ところで、外枠後辺部２２３には、排気筒４１からの熱影響で熱応力が作用する。そのため、このままでは、外枠後辺部２２３が天板本体２１に対しコーキング剤２２４による接着力に抗して上方に反るように変形し、外枠後辺部２２３と天板主体２１との間に隙間を生じてしまうことがある。 Incidentally, thermal stress acts on the outer frame rear side portion 223 due to the heat effect from the exhaust tube 41. Therefore, in this state, the outer frame rear side portion 223 is deformed so as to warp upward against the adhesive force of the caulking agent 224 with respect to the top plate body 21, and the outer frame rear side portion 223 and the top plate main body 21 are deformed. There may be gaps between them.

そこで、本実施形態では、外枠後辺部２２３の排気口２２５の前縁部上面に当接する上片部２４１と、天板本体２１の後部下面に当接する下片部２４２と、排気口２２５内で上片部２４１と下片部２４２とを連結する後端の折返し部２４３とを有するバネ材から成る係止具２４を設けて、この係止具２４により天板本体２１と外枠後辺部２２３とが挟持されるようにしている。尚、係止具２４は、排気口２２５の左右の両端部寄りに位置させて左右一対に設けられている。 Therefore, in the present embodiment, the upper piece 241 that contacts the upper surface of the front edge of the exhaust port 225 of the rear side 223 of the outer frame, the lower piece 242 that contacts the lower surface of the rear portion of the top plate body 21, and the exhaust port 225. A locking member 24 made of a spring material having a rear end folded portion 243 that connects the upper piece 241 and the lower piece 242 is provided, and the top plate body 21 and the rear frame rear are provided by this locking tool 24. The side part 223 is clamped. The locking tool 24 is provided in a pair of left and right positions near the left and right ends of the exhaust port 225.

本実施形態によれば、係止具２４の挟持力により天板本体２１に対し外枠後辺部２２３が上方に反るように変形することが防止され、外枠後辺部２２３と天板本体２１との間に隙間は生じない。そして、係止具２４を付加するだけであるため、部品点数の増加を抑えてコストダウンを図ることができる。更に、係止具２４は、排気ガード２３で目隠しされて外観に現れず、体裁を損なうことはない。 According to the present embodiment, the outer frame rear side portion 223 is prevented from being deformed so as to warp upward with respect to the top plate main body 21 due to the clamping force of the locking tool 24, and the outer frame rear side portion 223 and the top plate are prevented from being deformed. There is no gap between the main body 21. And since only the locking tool 24 is added, the increase in the number of parts can be suppressed and cost reduction can be achieved. Further, the locking tool 24 is hidden by the exhaust guard 23 and does not appear on the appearance, and the appearance is not impaired.

また、本実施形態では、外枠後辺部２２３に、排気口２２５の前縁で下方に折り返された折返し縁部２２６が設けられている。そして、係止具２４の下片部２４２に、折返し縁部２２６の前端に向けて斜め後上方に立上る左右一対の爪部２４４を設けている。爪部２４４と折返し縁部２２６との間には若干の隙間が空いているが、係止具２４の後方へのずれで上片部２４１が排気口２２５の前縁部上面から離脱する前に、爪部２４４が折返し縁部２２６の前端に係合して、係止具２４が抜け止めされる。 In the present embodiment, the outer frame rear side portion 223 is provided with a folded edge portion 226 that is folded downward at the front edge of the exhaust port 225. A pair of left and right claws 244 that rise obliquely upward toward the front end of the folded edge 226 is provided on the lower piece 242 of the locking tool 24. Although there is a slight gap between the claw portion 244 and the folded edge portion 226, before the upper piece portion 241 is detached from the upper surface of the front edge portion of the exhaust port 225 due to the rearward displacement of the locking tool 24. The claw portion 244 engages with the front end of the folded edge portion 226, and the locking tool 24 is prevented from coming off.

ところで、排気筒４１の上端は、排気口２２５の若干下方に位置していてもよいが、本実施形態では、排気筒４１の上端を排気口２２５を通してその上方に少許突出させている。そして、爪部２４４がその加工誤差で折返し縁部２２６の前端に係合しなくても、係止具２４の折返し部２４３が排気筒４２に当接して、係止具２４が抜け止めされるようにしている。何れにしても、係止具２４が抜け止めされることにより、係止具２４の脱落で外枠後辺部２２３の変形防止の効果が得られなくなることを回避できる。 By the way, the upper end of the exhaust tube 41 may be located slightly below the exhaust port 225, but in the present embodiment, the upper end of the exhaust tube 41 protrudes slightly above it through the exhaust port 225. Even if the claw portion 244 does not engage with the front end of the folded edge 226 due to the processing error, the folded portion 243 of the locking tool 24 comes into contact with the exhaust tube 42 and the locking tool 24 is prevented from coming off. I am doing so. In any case, it is possible to avoid the effect of preventing the deformation of the rear side portion 223 of the outer frame due to the dropping of the locking tool 24 by preventing the locking tool 24 from coming off.

尚、コンロ用天板２をコンロ本体１上に載置していない状態では、係止具２４を排気筒４１で抜け止めすることはできない。そのため、コンロ用天板２をコンロ本体１上に載置していない状態で係止具２４を抜け止めするには、下片部２４２に爪部２４４を設けることが必要である。 In addition, in a state where the stove top 2 is not placed on the stove main body 1, the locking tool 24 cannot be prevented from being removed by the exhaust pipe 41. Therefore, it is necessary to provide the claw portion 244 in the lower piece portion 242 in order to prevent the locking tool 24 from coming off while the stove top 2 is not placed on the stove body 1.

以上、本発明の実施形態について図面を参照して説明したが、本発明はこれに限定されない。例えば、上記実施形態では、係止具２４を左右一対に設けているが、比較的幅広の係止具を１個だけ設けることも可能である。 As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above-described embodiment, the pair of locking tools 24 are provided on the left and right, but it is also possible to provide only one relatively wide locking tool.
