Description

本発明の実施形態は、箱体の扉に関する。   Embodiments described herein relate generally to a box door.

従来、例えば冷蔵庫の断熱箱体などの開口を開閉する扉は、複数の部材を組み合わせて構成されている。例えば図23及び図24に示すように、従来構成の箱体の扉90は、扉の正面を構成する扉前面材91と、扉の背面を構成する扉背面材93と、扉正面材と扉背面材との間を塞ぐキャップ部材92と、を備えている。扉前面材91は、扉90の正面を構成する正面部911と、扉90の側面を構成する側面部912と、正面部911の縁部を扉90の厚み方向へ折り曲げた係合部913と、側面部912の後側縁部を正面部911と平行方向に折り曲げた後曲部914と、を一体に有している。キャップ部材92は、扉前面材91の係合部913を咥え込む被係合部921を有している。   Conventionally, for example, a door that opens and closes an opening such as a heat insulating box of a refrigerator is configured by combining a plurality of members. For example, as shown in FIGS. 23 and 24, a box door 90 having a conventional configuration includes a door front material 91 that configures the front of the door, a door back material 93 that configures the back of the door, a door front material, and a door. And a cap member 92 that closes the space between the back member and the back member. The door front member 91 includes a front portion 911 that configures the front surface of the door 90, a side surface portion 912 that configures the side surface of the door 90, and an engagement portion 913 in which an edge portion of the front portion 911 is bent in the thickness direction of the door 90. The rear side edge portion of the side surface portion 912 is integrally formed with a rear curved portion 914 that is bent in a direction parallel to the front surface portion 911. The cap member 92 has an engaged portion 921 that holds the engaging portion 913 of the door front material 91.

扉90は、例えば次のようにして組み立てられる。まず、図24の(a)に示すように、キャップ部材92を矢印A1方向へ移動させて、キャップ部材92の被係合部921に扉前面材91の係合部913を挿入する。次に、図24の(b)に示すように、キャップ部材92を、被係合部921と係合部913の被挿入部分を支点にして矢印A2方向へ回転させる。これにより、キャップ部材92が扉前面材91に嵌め込まれる。その後、図24の(c)に示すように、扉背面材93を、発泡ウレタンなどの発泡断熱材94を介在させて扉前面材91の後曲部914に当接させる。これにより、扉90が組み立てられる。   The door 90 is assembled as follows, for example. First, as shown in FIG. 24A, the cap member 92 is moved in the direction of arrow A1, and the engaging portion 913 of the door front member 91 is inserted into the engaged portion 921 of the cap member 92. Next, as shown in FIG. 24B, the cap member 92 is rotated in the direction of the arrow A2 with the inserted portions of the engaged portion 921 and the engaging portion 913 as fulcrums. Thereby, the cap member 92 is fitted into the door front member 91. Thereafter, as shown in FIG. 24C, the door back surface material 93 is brought into contact with the rear curved portion 914 of the door front surface material 91 with a foam heat insulating material 94 such as urethane foam interposed therebetween. Thereby, the door 90 is assembled.

しかしながら、上述の従来構成では、キャップ部材92の取り付けに、図24の(b)で示したような、キャップ部材92の大きな回転動作を伴う。そのため、組み付け性が悪く、また、キャップ部材92の回転動作によって係合部913が折れ曲がって凹凸などの変形が生じてしまうおそれがあった。そして、係合部913に凹凸が生じると、その凹凸によってキャップ部材92と係合部913との間に隙間が生じ、外観上見栄えが悪くなることに繋がる。   However, in the conventional configuration described above, the attachment of the cap member 92 is accompanied by a large rotation operation of the cap member 92 as shown in FIG. Therefore, the assembling property is poor, and the engaging portion 913 is bent by the rotation operation of the cap member 92, and there is a possibility that deformation such as unevenness may occur. When the engaging portion 913 is uneven, a gap is generated between the cap member 92 and the engaging portion 913 due to the unevenness, leading to a poor appearance.

Is formed. In this case, the first music part 224 is provided so as to slightly protrude from the surface part 221. The first music part 224 is provided over substantially the entire upper and lower edges of the surface part 221.

第2曲部225は、一方の側面部222の上下の両縁部を、対向する他方の側面部222側へ向かって直角方向へ折り曲げるようにして形成されている。第2曲部225の幅は、第1曲部224の幅と略等しい。第2曲部225は、表面部221付近から側面部222の全幅の半分程度の位置まで延びている。   The second curved portion 225 is formed such that both upper and lower edges of one side surface portion 222 are bent in a right-angle direction toward the opposite side surface portion 222 side. The width of the second music part 225 is substantially equal to the width of the first music part 224. The second curved portion 225 extends from the vicinity of the surface portion 221 to a position that is about half the full width of the side surface portion 222.

2つの閉塞部材23の基本的な構成は、上下対称形となっている。閉塞部材23は、例えば合成樹脂製の成型品である。閉塞部材23は、全体として一方向この場合左右方向に長い矩形の浅い容器状に構成されている。外板部材22の側面部222の上下端部において、対向する2つの側面部222間に挿入され、2つの側面部222間を閉塞する。すなわち、閉塞部材23は、扉20の上下端部であって、外板部材22の表面部221と左右側面部222と内部材21とで囲まれた部分に挿入される。そして、閉塞部材23は、外板部材22の表面部221と左右側面部222と内部材21とで囲まれた扉20の上下の開口を閉塞する。   The basic configuration of the two closing members 23 is vertically symmetrical. The closing member 23 is a molded product made of synthetic resin, for example. The closing member 23 is configured as a rectangular shallow container that is long in one direction as a whole, in this case in the left-right direction. The upper and lower end portions of the side surface portion 222 of the outer plate member 22 are inserted between the two opposing side surface portions 222 to close the space between the two side surface portions 222. That is, the closing member 23 is inserted into the upper and lower ends of the door 20 and surrounded by the surface portion 221, the left and right side portions 222, and the inner member 21 of the outer plate member 22. The closing member 23 closes the upper and lower openings of the door 20 surrounded by the surface portion 221, the left and right side portions 222, and the inner member 21 of the outer plate member 22.

図3及び図4にも示すように、閉塞部材23は、閉塞面部231、ヒンジ受部232、周壁部233、後壁部234、及びコーナー壁部235を一体に有している。閉塞面部231は、全体として一方向この場合横長の矩形の板状に構成されている。閉塞面部231は、閉塞部材23の容器状の底部を構成し、扉20の上下の側面部を構成する。ヒンジ受部232は、閉塞部材23の一方の端部側この場合右端部側に設けられている。ヒンジ受部232には、ヒンジ部14の軸部が挿入される。これにより、扉20は、ヒンジ部14を軸に回動可能に取り付けられる。   As shown in FIGS. 3 and 4, the closing member 23 integrally includes a closing surface portion 231, a hinge receiving portion 232, a peripheral wall portion 233, a rear wall portion 234, and a corner wall portion 235. The blocking surface portion 231 is configured in a horizontally long rectangular plate shape in one direction in this case as a whole. The closing surface portion 231 constitutes a container-like bottom portion of the closing member 23 and constitutes upper and lower side portions of the door 20. The hinge receiving portion 232 is provided on one end side of the closing member 23, in this case, on the right end side. The shaft portion of the hinge portion 14 is inserted into the hinge receiving portion 232. Thereby, the door 20 is attached to the hinge part 14 so that rotation is possible.

周壁部233は、閉塞面部231の周囲の縁部のうち、外板部材22側の長手方向の縁部と、その長手方向の辺部の両側の幅方向の縁部と、の3つの縁部に沿って設けられている。周壁部233は、閉塞面部231から上下方向であって扉20の内方へ向けて突出して設けられている。周壁部233は、閉塞面部231における内部材21側の縁部を除いて、閉塞面部231の3方の周囲を囲っている。   The peripheral wall portion 233 has three edge portions of a peripheral edge portion of the blocking surface portion 231, that is, a longitudinal edge portion on the outer plate member 22 side and a widthwise edge portion on both sides of the longitudinal side portion. It is provided along. The peripheral wall portion 233 is provided so as to protrude from the closing surface portion 231 in the vertical direction toward the inside of the door 20. The peripheral wall portion 233 surrounds the three sides of the closing surface portion 231 except for the edge portion of the closing surface portion 231 on the inner member 21 side.

後壁部234は、閉塞面部231の周囲の縁部のうち、周壁部233が存していない縁部、つまり内部材21側の縁部に沿って設けられている。後壁部234は、閉塞面部231から上下方向であって扉20の内方に向かって突出している。すなわち、後壁部234は、周壁部233と同じ方向へ向かって突出している。   The rear wall portion 234 is provided along an edge portion around the blocking surface portion 231 where the peripheral wall portion 233 does not exist, that is, an edge portion on the inner member 21 side. The rear wall portion 234 protrudes from the closing surface portion 231 in the vertical direction toward the inside of the door 20. That is, the rear wall portion 234 protrudes in the same direction as the peripheral wall portion 233.

コーナー壁部235は、閉塞部材23の左右両端部において閉塞面部231と反対側の角部に沿って設けられている。コーナー壁部235は、外板部材22の側面部222及びフランジ部223の外方に位置するように設けられている。この場合、コーナー壁部235は、側面部222及びフランジ部223を覆う覆い部として機能する。コーナー壁部235は、閉塞面部231から上下方向であって扉20の内方に向かって突出している。すなわち、コーナー壁部235は、周壁部233及び後壁部234と同じ方向へ向かって突出している。コーナー壁部235の一端部は、後壁部234に接続されている。一方、コーナー壁部235の他端部は、周壁部233に接続されていない。すなわち、コーナー壁部235は、周壁部233から離間している。   The corner wall portion 235 is provided along the corner on the opposite side of the closing surface portion 231 at both left and right end portions of the closing member 23. The corner wall portion 235 is provided so as to be located outside the side surface portion 222 and the flange portion 223 of the outer plate member 22. In this case, the corner wall portion 235 functions as a cover portion that covers the side surface portion 222 and the flange portion 223. The corner wall portion 235 protrudes from the closing surface portion 231 in the vertical direction toward the inside of the door 20. That is, the corner wall portion 235 protrudes in the same direction as the peripheral wall portion 233 and the rear wall portion 234. One end of the corner wall portion 235 is connected to the rear wall portion 234. On the other hand, the other end portion of the corner wall portion 235 is not connected to the peripheral wall portion 233. That is, the corner wall portion 235 is separated from the peripheral wall portion 233.

周壁部233の端部236は、コーナー壁部235から離間している。端部236とコーナー壁部235とは隙間が形成されている。この端部236は、図3及び図4に示すように、閉塞面部231側へ向かうほど、コーナー壁部235へ近づく傾斜状すなわちテーパ形状に形成されている。周壁部233の左右両端側部分、すなわち周壁部233における閉塞部材23の長手方向の両端側部分は、閉塞面部231の外縁の内側にある。閉塞面部231のうち、この周壁部233の外側に位置する部分によって、図3に示すように当て部237が構成されている。   An end 236 of the peripheral wall 233 is separated from the corner wall 235. A gap is formed between the end portion 236 and the corner wall portion 235. As shown in FIGS. 3 and 4, the end portion 236 is formed in an inclined shape, that is, a tapered shape that approaches the corner wall portion 235 toward the closing surface portion 231 side. The left and right end portions of the peripheral wall portion 233, that is, both end portions of the peripheral wall portion 233 in the longitudinal direction of the closing member 23 are inside the outer edge of the closing surface portion 231. A portion of the blocking surface portion 231 located outside the peripheral wall portion 233 constitutes a contact portion 237 as shown in FIG.

また、閉塞部材23は、図9に示すように、被挿入部238を有している。被挿入部238は、閉塞面部231と周壁部233の長手方向部分との接続部分に設けられている。被挿入部238は、外板部材22の表面部221側へ向かって開口した連続的又は断続的な溝形状に形成されている。この場合、被挿入部238は、閉塞部材23の長手方向つまり扉20の左右方向に沿った断続的な溝形状である。被挿入部238の溝幅は、外板部材22の厚み寸法と同程度かやや大きい寸法に設定されている。外板部材22の第1曲部224は、被挿入部238に挿入可能である。   Further, the closing member 23 has an inserted portion 238 as shown in FIG. The inserted portion 238 is provided at a connection portion between the blocking surface portion 231 and the longitudinal portion of the peripheral wall portion 233. The inserted portion 238 is formed in a continuous or intermittent groove shape opened toward the surface portion 221 side of the outer plate member 22. In this case, the inserted portion 238 has an intermittent groove shape along the longitudinal direction of the closing member 23, that is, the left-right direction of the door 20. The groove width of the inserted portion 238 is set to a size that is the same as or slightly larger than the thickness of the outer plate member 22. The first curved portion 224 of the outer plate member 22 can be inserted into the inserted portion 238.

また、閉塞部材23は、図3及び図4に示すように、当接部239、第1内壁部240、第2内壁部241、及びリブ部242を一体に有している。当接部239は、閉塞部材23の右端部分に設けられている。当接部239は、閉塞面部231から直角方向この場合上下方向における扉20の内方へ向かって突出するように設けられている。当接部239は、板状に構成されている。当接部239は、周壁部233の外側に設けられており、接続部243によって周壁部233に接続されている。当接部239は、図14に示すように、閉塞部材23が外板部材22の側面部222間に挿入された際に、側面部222の内側面に当接可能に構成されている。   Further, as shown in FIGS. 3 and 4, the closing member 23 integrally includes a contact part 239, a first inner wall part 240, a second inner wall part 241, and a rib part 242. The contact portion 239 is provided at the right end portion of the closing member 23. The abutting portion 239 is provided so as to protrude from the closing surface portion 231 in the right angle direction, in this case, the inward direction of the door 20. The contact part 239 is configured in a plate shape. The contact part 239 is provided outside the peripheral wall part 233 and is connected to the peripheral wall part 233 by a connection part 243. As shown in FIG. 14, the contact portion 239 is configured to be able to contact the inner side surface of the side surface portion 222 when the closing member 23 is inserted between the side surface portions 222 of the outer plate member 22.

第1内壁部240、第2内壁部241、及びリブ部242は、閉塞部材23の左右両端部分のそれぞれに設けられている。第1内壁部240、第2内壁部241、及びリブ部242は、板状であって、閉塞面部231から直角方向この場合上下方向における扉20の内方へ向かって突出するように設けられている。第1内壁部240は、外板部材22の表面部221に直角つまり側面部222に平行となっている。   The first inner wall portion 240, the second inner wall portion 241, and the rib portion 242 are provided on each of the left and right end portions of the closing member 23. The first inner wall portion 240, the second inner wall portion 241 and the rib portion 242 are plate-like and are provided so as to protrude from the closing surface portion 231 in the perpendicular direction, in this case, inward of the door 20 in the vertical direction. Yes. The first inner wall portion 240 is perpendicular to the surface portion 221 of the outer plate member 22, that is, parallel to the side surface portion 222.

第2内壁部241は、外板部材22の表面部221と平行つまり側面部222に直角になっている。この場合、第1内壁部240と第2内壁部241とは、略直角のL字状に形成されている。   The second inner wall portion 241 is parallel to the surface portion 221 of the outer plate member 22, that is, at a right angle to the side surface portion 222. In this case, the first inner wall portion 240 and the second inner wall portion 241 are formed in a substantially right-angled L shape.

リブ部242は、第1内壁部240に平行つまり第2内壁部241に直角に設けられている。リブ部242は、周壁部233と第1内壁部240とを接続している。これにより、リブ部242は、第1内壁部240及び第2内壁部241を補強している。   The rib portion 242 is provided in parallel to the first inner wall portion 240, that is, at a right angle to the second inner wall portion 241. The rib part 242 connects the peripheral wall part 233 and the first inner wall part 240. Thereby, the rib part 242 reinforces the first inner wall part 240 and the second inner wall part 241.

また、第1内壁部240には、図8及び図15に示すように、第1内壁部240を厚み方向に貫通させた穴部244が形成されている。穴部244は、第1内壁部240の上下方向の中心よりも閉塞面部231側寄りに設けられている。この場合、穴部244は、閉塞面部231から第1内壁部240の上下方向の中心部付近にかけて形成されている。穴部244は、扉20の厚み方向に長い矩形の穴形状に形成されている。   Moreover, as shown in FIG.8 and FIG.15, the hole part 244 which penetrated the 1st inner wall part 240 in the thickness direction is formed in the 1st inner wall part 240. As shown in FIG. The hole portion 244 is provided closer to the closing surface portion 231 side than the center of the first inner wall portion 240 in the vertical direction. In this case, the hole portion 244 is formed from the closing surface portion 231 to the vicinity of the central portion in the vertical direction of the first inner wall portion 240. The hole 244 is formed in a rectangular hole shape that is long in the thickness direction of the door 20.

規制部材25は、内部材21、外板部材22、及び閉塞部材23とは別体に構成されている。図3及び図4にも示すように、全体として扉20の上下方向に長く左右方向に扁平した矩形のブロック形状に形成されている。規制部材25は、当該規制部材25の長手方向に対して対称形に構成されている。これにより、扉20の四つの角部に設けられる規制部材25は、共通化されている。規制部材25は、例えば合成樹脂製の成型品である。規制部材25は、主体部251と、受け溝部252と、2つの弾性変形部253と、2つの爪部254と、を一体に有している。主体部251は、閉塞部材23の閉塞面部231側が開口した矩形の容器状に形成されている。この場合、図14に示すように、主体部251の幅寸法W1は、第1内壁部240と周壁部233との間の幅寸法W2よりも若干大きい。   The regulating member 25 is configured separately from the inner member 21, the outer plate member 22, and the closing member 23. As shown in FIGS. 3 and 4 as a whole, the door 20 is formed in a rectangular block shape that is long in the vertical direction and flattened in the horizontal direction. The restricting member 25 is configured symmetrically with respect to the longitudinal direction of the restricting member 25. Thereby, the regulating member 25 provided in the four corners of the door 20 is made common. The regulating member 25 is a molded product made of synthetic resin, for example. The restricting member 25 integrally includes a main body portion 251, a receiving groove portion 252, two elastic deformation portions 253, and two claw portions 254. The main body portion 251 is formed in a rectangular container shape in which the closing surface portion 231 side of the closing member 23 is opened. In this case, as shown in FIG. 14, the width dimension W <b> 1 of the main body 251 is slightly larger than the width dimension W <b> 2 between the first inner wall part 240 and the peripheral wall part 233.

受け溝部252は、外板部材22の側面部222側へ向かって突出するとともに、閉塞部材23の閉塞面部231側へ向かって開口している。受け溝部252の溝幅は、周壁部233の両端部236の厚み寸法よりも若干大きい。そのため、周壁部233の端部236は、規制部材25の受け溝部252の内側に入り込むことが可能となっている。この場合、端部236は、規制部材25の受け溝部252に対して力を作用させる作用部として機能する。受け溝部252は、作用部としての端部236から力を受ける受け部として機能する。   The receiving groove portion 252 protrudes toward the side surface portion 222 side of the outer plate member 22 and opens toward the closing surface portion 231 side of the closing member 23. The groove width of the receiving groove portion 252 is slightly larger than the thickness dimension of both end portions 236 of the peripheral wall portion 233. Therefore, the end portion 236 of the peripheral wall portion 233 can enter the inside of the receiving groove portion 252 of the regulating member 25. In this case, the end portion 236 functions as an action portion that applies a force to the receiving groove portion 252 of the regulating member 25. The receiving groove portion 252 functions as a receiving portion that receives a force from the end portion 236 as the action portion.

また、受け溝部252の底部255は、図11に示すように、受け溝部252の長手方向の中心部から外側へ向かうほど、受け溝部252が深くなるような傾斜状つまりテーパ形状に形成されている。換言すれば、受け溝部252の深さは、受け溝部252の長手方向の外側から中心部へ向かって次第に浅くなっている。この場合、底部255のテーパ形状の傾斜角度つまり勾配率は、周壁部233の端部236のテーパ形状の勾配率と略等しくなるように設定されている。   Further, as shown in FIG. 11, the bottom portion 255 of the receiving groove portion 252 is formed in an inclined shape, that is, a tapered shape such that the receiving groove portion 252 becomes deeper toward the outside from the center in the longitudinal direction of the receiving groove portion 252. . In other words, the depth of the receiving groove portion 252 is gradually shallower from the outside in the longitudinal direction of the receiving groove portion 252 toward the center portion. In this case, the inclination angle, that is, the gradient rate of the tapered shape of the bottom portion 255 is set to be substantially equal to the tapered gradient rate of the end portion 236 of the peripheral wall portion 233.

図4に示すように、2つの弾性変形部253は、それぞれ主体部251の一部に切り込みを入れて、幅の短い板状に構成されている。弾性変形部253は、閉塞部材23の長手方向、この場合、扉20の左右方向へ向かって弾性変形可能に構成されている。   As shown in FIG. 4, the two elastically deformable portions 253 are each formed in a plate shape with a short width by cutting a part of the main body portion 251. The elastic deformation portion 253 is configured to be elastically deformable in the longitudinal direction of the closing member 23, in this case, in the left-right direction of the door 20.

2つの爪部254は、それぞれ弾性変形部253から扉20の内方へ向かって突出して設けられている。2つの爪部254は、規制部材25の長手方向つまり扉20の上下方向対して左右対称に構成されている。爪部254の一方の面は、緩やかな傾斜面に形成されている。爪部254の他方の面は、弾性変形部253及び第1内壁部240に対して垂直な面に形成されている。この場合、2つの爪部254の垂直面は、相互に対向している。爪部254は、閉塞部材23の第1内壁部240に形成された穴部244に挿入可能に構成されている。そして、爪部254は、穴部244に挿入した状態で、爪部254の垂直面が穴部244の周囲の壁部に係止可能に構成されている。   The two claw portions 254 are provided so as to protrude from the elastic deformation portion 253 toward the inside of the door 20. The two claw portions 254 are configured symmetrically with respect to the longitudinal direction of the regulating member 25, that is, the vertical direction of the door 20. One surface of the claw portion 254 is formed in a gently inclined surface. The other surface of the claw portion 254 is formed on a surface perpendicular to the elastic deformation portion 253 and the first inner wall portion 240. In this case, the vertical surfaces of the two claw portions 254 face each other. The claw portion 254 is configured to be insertable into a hole portion 244 formed in the first inner wall portion 240 of the closing member 23. And the nail | claw part 254 is comprised in the state inserted in the hole part 244 so that the vertical surface of the nail | claw part 254 can be latched to the wall part around the hole part 244. FIG.

次に、扉20の組立手順について説明する。
まず作業者は、図9に示すように、外板部材22を例えば平坦な作業面100の上に置く。その際、外板部材22の表面部221の外面が作業面100に接するとともに、側面部222が作業面100に対して直角方向となるようにする。次に、作業者は、図4及び図9の矢印B1で示すように、閉塞部材23を、外板部材22の側面部222の端部において、対向する側面部222間つまり挿入部226に挿入する。その際、作業者は、閉塞部材23の長手方向両端部の周壁部233の端部236を、それぞれ外板部材22の左右両側のフランジ部223の表面部221側の面つまり扉20の内方側の面(以下、フランジ部223の内側面と称する)にあてがうようにする。
Next, the assembly procedure of the door 20 will be described.
First, as shown in FIG. 9, the worker places the outer plate member 22 on, for example, a flat work surface 100. At this time, the outer surface of the surface portion 221 of the outer plate member 22 is in contact with the work surface 100, and the side surface portion 222 is perpendicular to the work surface 100. Next, the operator inserts the closing member 23 between the opposing side surface portions 222, that is, into the insertion portion 226 at the end portion of the side surface portion 222 of the outer plate member 22, as indicated by an arrow B1 in FIGS. To do. At that time, the operator uses the end portions 236 of the peripheral wall portions 233 at both ends in the longitudinal direction of the closing member 23 to face the surface portion 221 side of the flange portions 223 on the left and right sides of the outer plate member 22, that is, the inside of the door 20 This is applied to the side surface (hereinafter referred to as the inner surface of the flange portion 223).

そして、作業者は、周壁部233の端部236をフランジ部223の内側面に沿わせて、閉塞部材23を扉20の内方(矢印B1方向)へ押し込む。このとき、閉塞部材23の端部236がフランジ部223の内側面に案内され、これにより閉塞部材23は表面部221に対して略平行に移動する。これにより、閉塞部材23は、外板部材22の側面部222間において、所定の位置に挿入される。この場合、閉塞部材23の端部236は、外板部材22に対する閉塞部材23の挿入を案内する案内部として機能する。   Then, the operator pushes the closing member 23 inward (in the direction of arrow B1) of the door 20 with the end portion 236 of the peripheral wall portion 233 along the inner surface of the flange portion 223. At this time, the end portion 236 of the closing member 23 is guided to the inner surface of the flange portion 223, whereby the closing member 23 moves substantially parallel to the surface portion 221. Thereby, the closing member 23 is inserted into a predetermined position between the side surface portions 222 of the outer plate member 22. In this case, the end portion 236 of the closing member 23 functions as a guide portion that guides the insertion of the closing member 23 into the outer plate member 22.

ここで、周壁部233の端部236がフランジ部223の内側面に接して案内部として機能している状態では、外板部材22の第1曲部224は閉塞部材23に接していない。つまり、閉塞部材23の周壁部233の端部236が外板部材22のフランジ部223の内側の面に接している状態では、外板部材22の第1曲部224は、閉塞部材23の被挿入部238に挿入されない。そのため、閉塞部材23を側面部222間に挿入する際に、閉塞部材23が第1曲部224に引っかかることがなくなる。したがって、作業者は、閉塞部材23の挿入状態を直接目視しなくても、閉塞部材23を円滑に側面部222間に挿入することができる。   Here, in a state where the end portion 236 of the peripheral wall portion 233 is in contact with the inner side surface of the flange portion 223 and functions as a guide portion, the first curved portion 224 of the outer plate member 22 is not in contact with the closing member 23. In other words, in a state where the end 236 of the peripheral wall portion 233 of the closing member 23 is in contact with the inner surface of the flange portion 223 of the outer plate member 22, the first curved portion 224 of the outer plate member 22 is covered with the covered member 23. It is not inserted into the insertion part 238. Therefore, when the closing member 23 is inserted between the side surface portions 222, the closing member 23 is not caught by the first curved portion 224. Therefore, the operator can smoothly insert the closing member 23 between the side surface portions 222 without directly viewing the insertion state of the closing member 23.

閉塞部材23が、側面部222の長手方向に沿って扉20の内方(矢印B1方向)へ押し込まれると、閉塞部材23の当て部237が外板部材22の第2曲部225に当接する。これにより、閉塞部材23は、扉20の内方へ更なる移動が規制される。その後、作業者は、図5及び図10の矢印B2で示すように、閉塞部材23を、作業面100側すなわち外板部材22の表面部221側へ押し込む。このとき、閉塞部材23は、閉塞部材23の当て部237が外板部材22の第2曲部225に接触しながら、第2曲部225に沿って移動する。これにより、閉塞部材23は、表面部221に対して直角方向つまり扉20の厚み方向に対して平行に移動する。この場合、外板部材22の第2曲部225及び閉塞部材23の当て部237は、閉塞部材23が、挿入部226つまり外板部材22の2つの側面部222間に挿入された状態で、閉塞部材23を扉20の厚み方向へ移動可能にする移動部として機能する。   When the closing member 23 is pushed inward (in the direction of arrow B1) of the door 20 along the longitudinal direction of the side surface portion 222, the contact portion 237 of the closing member 23 comes into contact with the second curved portion 225 of the outer plate member 22. . As a result, the closing member 23 is restricted from further moving inward of the door 20. Thereafter, the operator pushes the closing member 23 toward the work surface 100, that is, the surface portion 221 side of the outer plate member 22, as indicated by an arrow B <b> 2 in FIGS. 5 and 10. At this time, the closing member 23 moves along the second curved portion 225 while the contact portion 237 of the closing member 23 is in contact with the second curved portion 225 of the outer plate member 22. Accordingly, the closing member 23 moves in a direction perpendicular to the surface portion 221, that is, parallel to the thickness direction of the door 20. In this case, the second curved portion 225 of the outer plate member 22 and the contact portion 237 of the closing member 23 are in a state where the closing member 23 is inserted between the two side portions 222 of the insertion portion 226, that is, the outer plate member 22. It functions as a moving part that enables the closing member 23 to move in the thickness direction of the door 20.

そして、作業者は、閉塞部材23を表面部221側へ押し込むと、すなわち閉塞部材23を表面部221側へスライド移動させると、図6及び図11に示すように、その移動端において、閉塞部材23が表面部221に当接する。この場合、図11に示すように、閉塞部材23の被挿入部238に、外板部材22の第1曲部224が挿入される。そして、閉塞部材23の周壁部233における表面部221側の面が、表面部221に当接する。これにより、閉塞部材23は、表面部221側への更なる移動が規制される。   Then, when the operator pushes the closing member 23 toward the surface portion 221, that is, when the closing member 23 is slid and moved toward the surface portion 221, as shown in FIGS. 6 and 11, at the moving end, the closing member 23 abuts on the surface portion 221. In this case, as shown in FIG. 11, the first curved portion 224 of the outer plate member 22 is inserted into the inserted portion 238 of the closing member 23. The surface on the surface portion 221 side of the peripheral wall portion 233 of the closing member 23 comes into contact with the surface portion 221. Thereby, the closing member 23 is restricted from further movement toward the surface portion 221.

次に、作業者は、図7及び図11の矢印B3で示すように、規制部材25を、外板部材22と閉塞部材23との間に挿入する。その際、図14に示すように、閉塞部材23の周壁部233の端部236を、規制部材25の受け溝部252に嵌め込むようにする。そして、作業者は、規制部材25を、フランジ部223の内側面に沿わせながら、閉塞部材23の閉塞面部231側へ押し込む。その際、規制部材25は、フランジ部223の内側面によって、外板部材22と閉塞部材23との間の所定の位置に案内される。   Next, the operator inserts the regulating member 25 between the outer plate member 22 and the closing member 23 as indicated by an arrow B3 in FIGS. At that time, as shown in FIG. 14, the end portion 236 of the peripheral wall portion 233 of the closing member 23 is fitted into the receiving groove portion 252 of the regulating member 25. Then, the operator pushes the regulating member 25 into the closing surface portion 231 side of the closing member 23 along the inner surface of the flange portion 223. At that time, the regulating member 25 is guided to a predetermined position between the outer plate member 22 and the closing member 23 by the inner surface of the flange portion 223.

規制部材25が、外板部材22と閉塞部材23との間における所定の位置に挿入されると、規制部材25の受け溝部252におけるテーパ形状の底部255と、閉塞部材23の周壁部233におけるテーパ形状の端部236とが、くさびとして作用する。これにより、規制部材25は、閉塞部材23の周壁部233の端部236と、外板部材22のフランジ部223との間を押し広げる。   When the restricting member 25 is inserted at a predetermined position between the outer plate member 22 and the closing member 23, the tapered bottom portion 255 in the receiving groove portion 252 of the restricting member 25 and the taper in the peripheral wall portion 233 of the closing member 23. The shaped end 236 acts as a wedge. Accordingly, the regulating member 25 pushes between the end portion 236 of the peripheral wall portion 233 of the closing member 23 and the flange portion 223 of the outer plate member 22.

すなわち、規制部材25は、フランジ部223と閉塞部材23との間に挿入されることによって、フランジ部223を押圧する。この場合、閉塞部材23の周壁部233の端部236と、規制部材25の受け溝部252の底部255とが、それぞれ傾斜状に形成されている。これにより、規制部材25は、規制部材25が閉塞面部231側へ押し込まれることに伴って、フランジ部223を押圧する力が増大する。   That is, the restriction member 25 presses the flange portion 223 by being inserted between the flange portion 223 and the closing member 23. In this case, the end portion 236 of the peripheral wall portion 233 of the closing member 23 and the bottom portion 255 of the receiving groove portion 252 of the restricting member 25 are each formed in an inclined shape. Thereby, the force which presses the flange part 223 increases the control member 25 in connection with the control member 25 being pushed in the obstruction | occlusion surface part 231 side.

そして、フランジ部223が規制部材25から力を受けたことによって、外板部材22全体が、図12における矢印B4で示す方向へ移動するとともに、規制部材25が矢印B5方向へ移動する。つまり、規制部材25と外板部材22とが相互に引き寄せられて、外板部材22のフランジ部223の外側面と、閉塞部材23のコーナー壁部235の内側面とが密着する方向へ移動する。また、外板部材22の第1曲部224が、閉塞部材23の被挿入部238の内側へより入り込む。これらにより、外板部材22と閉塞部材23とが密着し、外板部材22と閉塞部材23との隙間が密に埋められる。   When the flange portion 223 receives a force from the restricting member 25, the entire outer plate member 22 moves in the direction indicated by the arrow B4 in FIG. 12, and the restricting member 25 moves in the direction of the arrow B5. That is, the regulating member 25 and the outer plate member 22 are attracted to each other, and move in a direction in which the outer surface of the flange portion 223 of the outer plate member 22 and the inner surface of the corner wall portion 235 of the closing member 23 are in close contact with each other. . Further, the first curved portion 224 of the outer plate member 22 enters more into the inserted portion 238 of the closing member 23. As a result, the outer plate member 22 and the closing member 23 are in close contact with each other, and the gap between the outer plate member 22 and the closing member 23 is tightly filled.

そして、規制部材25のくさびとしての作用により、外板部材22のフランジ部223の外側面と閉塞部材23のコーナー壁部235の内側面とが、圧力を受けた状態で接触する。同様に、規制部材25のくさびとしての作用により、外板部材22の閉塞面部231の内側面と閉塞部材23の周壁部233の閉塞面部231側の面とが、圧力を受けた状態で接触する。これにより、閉塞部材23が、外板部材22の側面部222間において強固に固定される。このようにして、規制部材25は、閉塞部材23が移動端に位置する状態において閉塞部材23の移動を規制する規制手段として機能する。   Then, due to the action of the restricting member 25 as a wedge, the outer surface of the flange portion 223 of the outer plate member 22 and the inner surface of the corner wall portion 235 of the closing member 23 are in contact with each other under pressure. Similarly, due to the action of the regulating member 25 as a wedge, the inner surface of the closing surface portion 231 of the outer plate member 22 and the surface on the closing surface portion 231 side of the peripheral wall portion 233 of the closing member 23 are in contact with each other under pressure. . Thereby, the closing member 23 is firmly fixed between the side surface portions 222 of the outer plate member 22. In this way, the regulating member 25 functions as a regulating means that regulates the movement of the closing member 23 in a state where the closing member 23 is located at the moving end.

また、規制部材25の幅寸法W1は、図14に示すように、第1内壁部240と周壁部233との間の幅寸法W2よりも若干大きい。そのため、規制部材25が第1内壁部240と周壁部233との間に挿入されると、第1内壁部240と周壁部233とを離間させる方向へ力が作用する。この場合、第1内壁部240には、第1内壁部240に対して直角方向に設けられた第2内壁部241が接続されているため、周壁部233に対して第1内壁部240の変形は小さい。周壁部233は、規制部材25から受けた力を、接続部243を介して当接部239へ伝える。   Further, as shown in FIG. 14, the width dimension W1 of the restricting member 25 is slightly larger than the width dimension W2 between the first inner wall portion 240 and the peripheral wall portion 233. Therefore, when the regulating member 25 is inserted between the first inner wall portion 240 and the peripheral wall portion 233, a force acts in a direction to separate the first inner wall portion 240 and the peripheral wall portion 233. In this case, since the second inner wall portion 241 provided in the direction perpendicular to the first inner wall portion 240 is connected to the first inner wall portion 240, the deformation of the first inner wall portion 240 with respect to the peripheral wall portion 233 is performed. Is small. The peripheral wall portion 233 transmits the force received from the restriction member 25 to the contact portion 239 via the connection portion 243.

つまり、規制部材25は、当接部239と第1内壁部240との間に挿入され、周壁部233を、第1内壁部240から離間する方向へ押し広げる。そして、規制部材25は、周壁部233及び接続部243を介して当接部239を第1内壁部240から離間する方向へ押し広げ、これにより、当接部239を、外板部材22の側面部222の内側面に密着させる。その結果、閉塞部材23が、外板部材22の側面部222間においてさらに強固に固定される。   That is, the restricting member 25 is inserted between the contact portion 239 and the first inner wall portion 240 and pushes the peripheral wall portion 233 away from the first inner wall portion 240. Then, the regulating member 25 spreads the contact portion 239 in a direction away from the first inner wall portion 240 via the peripheral wall portion 233 and the connection portion 243, whereby the contact portion 239 is moved to the side surface of the outer plate member 22. The inner surface of the portion 222 is closely attached. As a result, the closing member 23 is more firmly fixed between the side surface portions 222 of the outer plate member 22.

そして、図8及び図12の状態になるまで規制部材25が押し込まれると、規制部材25の一方の爪部254は、第1内壁部240の穴部244に係止する。そのため、規制部材25は、閉塞部材23から抜ける方向つまり閉塞部材23から離間する方向への移動が規制される。これにより、規制部材25は、外板部材22と閉塞部材23との間に固定される。なお、規制部材25の取りはずしは、次のようにして行う。作業者は、工具等で弾性変形部253を押して、弾性変形部253を、第1内壁部240から離間する方向へ弾性変形させる。これにより、爪部254が第1内壁部240の穴部244から抜ける。すると、爪部254と穴部244とが係止すことよる、規制部材25の移動の規制が解除され、規制部材25の取り外しが可能になる。   Then, when the regulating member 25 is pushed in until the state shown in FIGS. 8 and 12, the one claw portion 254 of the regulating member 25 is locked in the hole portion 244 of the first inner wall portion 240. For this reason, the movement of the restricting member 25 in the direction away from the closing member 23, that is, in the direction away from the closing member 23 is restricted. Thereby, the regulating member 25 is fixed between the outer plate member 22 and the closing member 23. The restriction member 25 is removed as follows. The operator presses the elastic deformation portion 253 with a tool or the like to elastically deform the elastic deformation portion 253 in a direction away from the first inner wall portion 240. As a result, the claw portion 254 comes out of the hole portion 244 of the first inner wall portion 240. Then, the restriction | limiting of the movement of the control member 25 by the nail | claw part 254 and the hole part 244 latching is cancelled | released, and the removal of the control member 25 is attained.

作業者は、規制部材25を取り付けた後、図13に示すように、内部材21を、外板部材22と閉塞部材23との組立体に取り付ける。その際、作業者は、内部材21の外周部分を、外板部材22のフランジ部223及び閉塞部材23の後壁部234に当接させる。これにより、内部に空間を有する内部材21と外板部材22と閉塞部材23との組立体が構成される。そして、作業者は、内部材21と外板部材22と閉塞部材23との組立体の内部に、断熱材として例えば現場発泡型の発泡ウレタンを充填する。これにより、断熱性を有する扉20が完成する。なお、扉20の断熱材は、発泡ウレタンに換えて又は発泡ウレタンと共に、例えば真空断熱パネルを設けても良い。この場合、例えば内部材21が取り付けられる前に、真空断熱パネルが外板部材22の内側に配置される。   After attaching the regulating member 25, the worker attaches the inner member 21 to the assembly of the outer plate member 22 and the closing member 23 as shown in FIG. 13. At that time, the operator brings the outer peripheral portion of the inner member 21 into contact with the flange portion 223 of the outer plate member 22 and the rear wall portion 234 of the closing member 23. As a result, an assembly of the inner member 21, the outer plate member 22, and the closing member 23 having a space therein is formed. Then, the worker fills the inside of the assembly of the inner member 21, the outer plate member 22, and the closing member 23 with, for example, in-situ foamed urethane foam as a heat insulating material. Thereby, the door 20 which has heat insulation is completed. In addition, the heat insulating material of the door 20 may be provided with, for example, a vacuum heat insulating panel instead of the urethane foam or together with the urethane foam. In this case, for example, the vacuum heat insulating panel is disposed inside the outer plate member 22 before the inner member 21 is attached.

これによれば、扉20の組立において、作業者は、閉塞部材23を、外板部材22の表面部221に当接しない状態で2つの側面部222間に挿入した後に、表面部221に対して直角方向であって表面部221に近づく方向へ移動させる。したがって、閉塞部材23を、大きな回転動作を伴うことなく外板部材22に取り付けることができる。そのため、閉塞部材23の回転動作に伴って外板部材22が折れ曲がることを抑制することができる。作業者は、容易に閉塞部材23を外板部材22に取り付けることができ、作業性が向上する。また、これによれば、外板部材22に凹凸が生じることを抑制することができ、その結果、閉塞部材23と外板部材22との隙間が生じ難くなり、外観上の見栄えも良くなる。   According to this, in assembling the door 20, the operator inserts the closing member 23 between the two side surface parts 222 without contacting the surface part 221 of the outer plate member 22, and Are moved in a direction perpendicular to the surface portion 221. Therefore, the closing member 23 can be attached to the outer plate member 22 without a large rotation operation. Therefore, it is possible to prevent the outer plate member 22 from being bent along with the rotation operation of the closing member 23. The operator can easily attach the closing member 23 to the outer plate member 22 and workability is improved. Moreover, according to this, it can suppress that an unevenness | corrugation arises in the outer-plate member 22, As a result, the clearance gap between the closure member 23 and the outer-plate member 22 becomes difficult to produce, and the external appearance is also improved.

閉塞部材23の外板部材22に取り付けられた状態である移動端において、閉塞部材23の被挿入部238には、外板部材22の第1曲部224が挿入されている。これによれば、閉塞部材23の移動が規制され、閉塞部材23が外板部材22から不用意に外れることを防止することができる。また、閉塞部材23と外板部材22との隙間が目立たなくなり、外観上の見栄えも向上する。   At the moving end that is attached to the outer plate member 22 of the closing member 23, the first curved portion 224 of the outer plate member 22 is inserted into the inserted portion 238 of the closing member 23. According to this, the movement of the closing member 23 is restricted, and the closing member 23 can be prevented from being carelessly detached from the outer plate member 22. Further, the gap between the closing member 23 and the outer plate member 22 becomes inconspicuous, and the appearance is improved.

また、作業者は、閉塞部材23を外板部材22の挿入部226に挿入する際、閉塞部材23の当て部237が外板部材22の第2曲部225に当たったことを目安にすることができる。これにより、作業者は、閉塞部材23と外板部材22との取り付け具合をいちいち目視しながら作業する必要が無くなるため、作業性が向上される。   In addition, when inserting the closing member 23 into the insertion portion 226 of the outer plate member 22, the operator uses as a guide that the contact portion 237 of the closing member 23 has hit the second curved portion 225 of the outer plate member 22. Can do. This eliminates the need for the operator to work while visually observing how the closing member 23 and the outer plate member 22 are attached, thereby improving workability.

扉20は、閉塞部材23が外板部材22に取り付けられた状態すなわち閉塞部材23が移動端に位置する状態において、閉塞部材23の移動を規制する規制手段として規制部材25を備えている。これによれば、閉塞部材23が外板部材22から不用意に外れることをさらに効果的に防止することができる。   The door 20 includes a restricting member 25 as a restricting means for restricting movement of the closing member 23 in a state where the closing member 23 is attached to the outer plate member 22, that is, in a state where the closing member 23 is located at the moving end. According to this, it can prevent more effectively that the obstruction | occlusion member 23 remove | deviates from the outer-plate member 22 carelessly.

規制部材25は、閉塞部材23の当接部239と第1内壁部240との間に挿入されて、当接部239を第1内壁部240から離間する方向へ押し広げて当接部239を外板部材22の側面部222に密着させる。これによれば、閉塞部材23が、外板部材22の側面部222間において強固に固定される。   The restricting member 25 is inserted between the contact portion 239 of the closing member 23 and the first inner wall portion 240, and pushes the contact portion 239 away from the first inner wall portion 240 so that the contact portion 239 is moved. The outer plate member 22 is brought into close contact with the side surface portion 222. According to this, the closing member 23 is firmly fixed between the side portions 222 of the outer plate member 22.

規制部材25は、フランジ部223の内側面によって、外板部材22と閉塞部材23との間の所定の位置に案内される。これによれば、規制部材25の挿入位置が閉塞部材23や外板部材22の内側に隠れて作業者から見え難い場合であっても、作業者は、容易に規制部材25を取り付けることができる。その結果、作業性の向上が図られる。   The restricting member 25 is guided to a predetermined position between the outer plate member 22 and the closing member 23 by the inner surface of the flange portion 223. According to this, even if the insertion position of the regulating member 25 is hidden inside the closing member 23 or the outer plate member 22 and is difficult for the operator to see, the operator can easily attach the regulating member 25. . As a result, workability is improved.

閉塞部材23は、外板部材22に対する挿入を案内する案内部として、周壁部233の端部236を有している。これによれば、閉塞部材23の挿入位置が作業者から見え難い場合であっても、作業者は、容易に閉塞部材23を外板部材22に取り付けることができる。すなわち、作業者は、外板部材22の第1曲部224に閉塞部材23の被挿入部238に入るかどうかを確認するために、作業面100の下方に潜り込んで直接目視しなくても、容易に閉塞部材23を外板部材22に取り付けることができる。その結果、作業性が向上する。   The closing member 23 has an end portion 236 of the peripheral wall portion 233 as a guide portion that guides insertion into the outer plate member 22. According to this, even if it is difficult for the operator to see the insertion position of the closing member 23, the operator can easily attach the closing member 23 to the outer plate member 22. That is, the operator can check whether the first bent portion 224 of the outer plate member 22 enters the inserted portion 238 of the closing member 23 without diving under the work surface 100 and directly observing it. The closing member 23 can be easily attached to the outer plate member 22. As a result, workability is improved.

更には、閉塞部材23と外板部材22とが適切でない位置で当たることによって生じる、閉塞部材23や外板部材22の外観面の傷や塗装剥げなどを防ぐことができる。すなわち、例えば図23に示す従来構成では、キャップ部材92の被係合部921を押し込んで、被係合部921に扉正面材91の係合部913を挿入する際、被係合部921と係合部913との位置関係が見え難い。そのため、係合部913の端部が、キャップ部材92に当たってキャップ部材92が傷つけられるおそれがある。一方、本実施形態によれば、閉塞部材23の挿入位置が作業者から見え難い場合であっても、作業者は、容易に閉塞部材23を外板部材22に取り付けることができるため、係合部913の端部が、キャップ部材92に当たってキャップ部材92が傷つけられることを低減することができる。   Furthermore, it is possible to prevent scratches on the external surfaces of the closing member 23 and the outer plate member 22 and peeling of the paint, which are caused when the closing member 23 and the outer plate member 22 hit at an inappropriate position. 23, for example, when the engaged portion 921 of the cap member 92 is pushed in and the engaging portion 913 of the door front material 91 is inserted into the engaged portion 921, The positional relationship with the engaging portion 913 is difficult to see. Therefore, the end of the engaging portion 913 may hit the cap member 92 and the cap member 92 may be damaged. On the other hand, according to this embodiment, even if it is difficult for the operator to see the insertion position of the closing member 23, the operator can easily attach the closing member 23 to the outer plate member 22. It can reduce that the edge part of the part 913 hits the cap member 92, and the cap member 92 is damaged.

そして、端部236がフランジ部223の内側面に接触している状態では、閉塞部材23の表面側部分は、外板部材22に当接してない。これによれば、閉塞部材23を外板部材22の側面部222間に挿入する際に、閉塞部材23の表面側部分が外板部材22に当たってその挿入が妨げられることがない。よって、作業者は、さらに容易に閉塞部材23を外板部材22に取り付けることができる。その結果、作業性がさらに向上する。   In the state where the end portion 236 is in contact with the inner surface of the flange portion 223, the surface side portion of the closing member 23 is not in contact with the outer plate member 22. According to this, when the closing member 23 is inserted between the side portions 222 of the outer plate member 22, the surface side portion of the closing member 23 does not hit the outer plate member 22 and the insertion is not hindered. Therefore, the operator can attach the closing member 23 to the outer plate member 22 more easily. As a result, workability is further improved.

規制部材25は、フランジ部223と閉塞部材23との間に挿入されることによってフランジ部223を押圧する力が生じるように構成されている。そして、外板部材22は、フランジ部223が規制部材25から力を受けることで閉塞部材23に密着する方向へ移動する。これによれば、規制部材25の挿入によって、閉塞部材23と外板部材22とをさらに強固に固定させることができる。また、閉塞部材23と外板部材22との隙間を低減し、外観上の見栄えをさらに向上させることができる。   The restriction member 25 is configured to generate a force that presses the flange portion 223 when inserted between the flange portion 223 and the closing member 23. The outer plate member 22 moves in a direction in which the flange portion 223 is in close contact with the closing member 23 when the flange portion 223 receives a force from the regulating member 25. According to this, the closing member 23 and the outer plate member 22 can be more firmly fixed by inserting the regulating member 25. Moreover, the clearance gap between the closure member 23 and the outer-plate member 22 can be reduced, and the external appearance can be improved further.

規制部材25は、閉塞部材23に挿入されることに伴ってフランジ部223を押圧する力が増大するように構成されている。これによれば、作業者は、規制部材25を、外板部材22と閉塞部材23との間に押し込みやすくなり、作業性が向上する。   The restriction member 25 is configured to increase the force that presses the flange portion 223 as it is inserted into the closing member 23. According to this, the operator can easily push the regulating member 25 between the outer plate member 22 and the closing member 23, and the workability is improved.

閉塞部材23は、フランジ部223を覆う覆い部としてコーナー壁部235を有している。これによれば、作業者は、コーナー壁部235の内側にフランジ部223を入れるようにして、閉塞部材23を外板部材22に取り付けることができる。そのため、作業者は、閉塞部材23を外板部材22に挿入する際の位置を決める目安として、コーナー壁部235を用いることができる。その結果、閉塞部材23の取り付けが容易となり、作業性の向上が図られる。また、コーナー壁部235は、フランジ部223及び側面部222の一部を覆っている。そのため、扉20の角部において、外板部材22と閉塞部材23との隙間が隠されて、外観上の見栄えが向上する。   The closing member 23 has a corner wall portion 235 as a covering portion that covers the flange portion 223. According to this, the operator can attach the closing member 23 to the outer plate member 22 by inserting the flange portion 223 inside the corner wall portion 235.

次に、本実施形態の扉20の組立手順について説明する。
本実施形態の扉20も、上記第1実施形態の扉20と同様に、平坦な作業面100上で組み立てられる。作業者は、閉塞部材23を、図19及び図21の矢印C1で示すように作業面100に対して水平方向へ移動させて、外板部材22の対向する側面部222間つまり挿入部226に挿入する。閉塞部材23の閉塞面部231が、外板部材22のフランジ部223の先端部にある第1係合部441に当たると、閉塞部材23の矢印C1方向への移動が規制される。
Next, the assembly procedure of the door 20 of this embodiment is demonstrated.
Similarly to the door 20 of the first embodiment, the door 20 of the present embodiment is also assembled on the flat work surface 100. The operator moves the closing member 23 in the horizontal direction with respect to the work surface 100 as indicated by an arrow C1 in FIGS. 19 and 21, and between the opposing side surface portions 222 of the outer plate member 22, that is, in the insertion portion 226. insert. When the closing surface portion 231 of the closing member 23 hits the first engaging portion 441 at the distal end portion of the flange portion 223 of the outer plate member 22, the movement of the closing member 23 in the arrow C1 direction is restricted.

次に、作業者は、閉塞部材23を、図19及び図21の矢印C1方向へ力を加えつつ、図20及び図22の矢印C2で示すように作業面100側へ移動させる。すると、図20に示すように、その移動端において、閉塞部材23の被挿入部238に、外板部材22の第1曲部224が挿入される。この場合、外板部材22の第1係合部411は、図20に示すように、閉塞部材23の第1被係合部421に挿入されて係合する。また、閉塞部材23の第2被係合部422は、図22に示すように、外板部材22の第2係合部412に挿入されて係合する。また、閉塞部材23の第3被係合部423は、図20に示すように、外板部材22の第3係合部413に挿入されて係合する。そして、閉塞部材23の第4被係合部424は、詳細は図示しないが、外板部材22の第4係合部414に挿入されて係合する。   Next, the operator moves the closing member 23 toward the work surface 100 as indicated by an arrow C2 in FIGS. 20 and 22 while applying a force in the direction of the arrow C1 in FIGS. Then, as shown in FIG. 20, at the moving end, the first curved portion 224 of the outer plate member 22 is inserted into the inserted portion 238 of the closing member 23. In this case, the first engaging portion 411 of the outer plate member 22 is inserted into and engaged with the first engaged portion 421 of the closing member 23 as shown in FIG. Further, the second engaged portion 422 of the closing member 23 is inserted into and engaged with the second engaging portion 412 of the outer plate member 22 as shown in FIG. Further, as shown in FIG. 20, the third engaged portion 423 of the closing member 23 is inserted into and engaged with the third engaging portion 413 of the outer plate member 22. The fourth engaged portion 424 of the closing member 23 is inserted into and engaged with the fourth engaging portion 414 of the outer plate member 22, although details are not shown.

このように、閉塞部材23が外板部材22に対する移動方向の移動端に位置した場合に、外板部材22の各係合部411〜414と、閉塞部材23の各被係合部421〜424とが係合する。そして、これにより、閉塞部材23と外板部材22との相対的な移動が規制される。また、この場合、外板部材22の各係合部411〜414と、閉塞部材23の各被係合部421〜424とが係合することで、例えば「カチッ」というような音と、その音に伴う振動が発生する。これにより、作業者は、閉塞部材23が外板部材22の所定位置に取り付けられたことを音や触感によって知覚することができる。   As described above, when the closing member 23 is positioned at the moving end in the moving direction with respect to the outer plate member 22, the engaging portions 411 to 414 of the outer plate member 22 and the engaged portions 421 to 424 of the closing member 23. And engage. As a result, the relative movement between the closing member 23 and the outer plate member 22 is restricted. Further, in this case, the engaging portions 411 to 414 of the outer plate member 22 and the engaged portions 421 to 424 of the closing member 23 are engaged, for example, a sound such as “click”, Vibration accompanied by sound occurs. Thereby, the operator can perceive that the closing member 23 is attached to the predetermined position of the outer plate member 22 by sound or tactile sensation.

その後、作業者は、上記第1実施形態と同様に、内部材21を、外板部材22と閉塞部材23との組立体に取り付ける。そして、作業者は、内部材21と外板部材22と閉塞部材23との組立体の内部に、断熱材として例えば現場発泡型の発泡ウレタンを充填する。これにより、断熱性を有する扉20が完成する。   Thereafter, the worker attaches the inner member 21 to the assembly of the outer plate member 22 and the closing member 23 as in the first embodiment. Then, the worker fills the inside of the assembly of the inner member 21, the outer plate member 22, and the closing member 23 with, for example, in-situ foamed urethane foam as a heat insulating material. Thereby, the door 20 which has heat insulation is completed.

これによれば、上記第1実施形態と同様に、閉塞部材23を、大きな回転動作を伴うことなく外板部材22に取り付けることができる。そのため、上記第1実施形態と同様の作用効果が得られる。更に、これによれば、扉20は、外板部材22及び閉塞部材23とは別体に構成された規制手段としての規制部材25を備えていない。すなわち、本実施形態において、外板部材22と閉塞部材23との相対的な移動を規制する規制手段は、外板部材22及び閉塞部材23と一体に形成されている。したがって、第1実施形態に比べて規制部材25分、部品点数を削減することができ、その結果、コストを削減や軽量化を行うことができる。また、規制部材25を取り付ける手数を減らすことができるため、作業効率の更なる向上が図られる。   According to this, similarly to the said 1st Embodiment, the obstruction | occlusion member 23 can be attached to the outer plate member 22 without accompanying a big rotation operation | movement. Therefore, the same effect as the first embodiment can be obtained. Further, according to this, the door 20 does not include a regulating member 25 as a regulating means configured separately from the outer plate member 22 and the closing member 23. That is, in this embodiment, the restricting means for restricting the relative movement between the outer plate member 22 and the closing member 23 is formed integrally with the outer plate member 22 and the closing member 23. Accordingly, the number of parts can be reduced by 25 minutes compared with the first embodiment, and as a result, the cost can be reduced and the weight can be reduced. Further, since the number of steps for attaching the regulating member 25 can be reduced, the working efficiency can be further improved.

ここで、例えば上記第1実施形態において、作業者が規制部材25の取り付けを忘れると、外板部材22と閉塞部材23との相対的な移動が規制されなくなる。この状態で、扉20の内部に発泡ウレタンが充填されて膨張すると、その膨張力によって外板部材22が浮き上がる等して外観品質に影響が生じ易くなる。一方、第2実施形態では、規制部材25を用いることなく、閉塞部材23を外板部材22に取り付けることで、必然的に閉塞部材23と外板部材22との相対的な移動の規制が行われる。したがって、規制部材25の付け忘れによる人為的な作業ミスを防ぐことができ、その結果、扉20の更なる品質向上を図ることができる。   Here, for example, in the first embodiment, if the operator forgets to attach the restricting member 25, the relative movement between the outer plate member 22 and the closing member 23 is not restricted. In this state, when the inside of the door 20 is filled with urethane foam and expands, the outer plate member 22 is lifted by the expansion force and the appearance quality is easily affected. On the other hand, in the second embodiment, the relative movement of the closing member 23 and the outer plate member 22 is inevitably restricted by attaching the closing member 23 to the outer plate member 22 without using the restricting member 25. Is called. Therefore, it is possible to prevent a human error due to forgetting to attach the regulating member 25, and as a result, it is possible to further improve the quality of the door 20.

また、第1係合部411は、フランジ部223の長手方向の端部から閉塞部材23側へ向かって延び出るように板状に形成されている。そして、第1被係合部421は、第1係合部411を挿入可能な溝状に形成されている。これによれば、第1係合部411と第1被係合部421とが面で係止される。そのため、外板部材22と閉塞部材23との相対的な移動をより強固に規制することができる。   The first engaging portion 411 is formed in a plate shape so as to extend from the longitudinal end portion of the flange portion 223 toward the closing member 23 side. The first engaged portion 421 is formed in a groove shape into which the first engaging portion 411 can be inserted. According to this, the 1st engaging part 411 and the 1st to-be-engaged part 421 are latched by a surface. Therefore, the relative movement between the outer plate member 22 and the closing member 23 can be more firmly regulated.

また、第2係合部412は、外板部材22の側面部222の長手方向の端部を切り欠いて切欠き形状に形成されている。そして、第2被係合部422は、第2係合部412に挿入可能な突形状に形成されている。これによれば、作業者が、側面部222の端部に沿って閉塞部材23を移動させることにより、第2被係合部422を第2係合部412に挿入することができる。そのため、作業がし易くなり、作業性の向上が図られる。   Further, the second engaging portion 412 is formed in a notch shape by notching the end portion in the longitudinal direction of the side surface portion 222 of the outer plate member 22. The second engaged portion 422 is formed in a protruding shape that can be inserted into the second engaging portion 412. According to this, the operator can insert the second engaged portion 422 into the second engaging portion 412 by moving the closing member 23 along the end portion of the side surface portion 222. Therefore, it becomes easy to work, and workability is improved.

また、第3係合部413及び第4係合部414は、外板部材22に形成された穴によって構成されている。そして、第3被係合部423及び第4被係合部424は、それぞれ第3係合部413及び第4係合部414に挿入される突形状に形成されている。これによれば、第3被係合部423及び第4被係合部424が、それぞれ穴形状の第3係合部413及び第4係合部414に挿入されて係止されることで、外板部材22と閉塞部材23との左右方向及び前後方向への移動をより効果的に規制することができる。   Further, the third engaging portion 413 and the fourth engaging portion 414 are configured by holes formed in the outer plate member 22. And the 3rd to-be-engaged part 423 and the 4th to-be-engaged part 424 are formed in the protrusion shape inserted in the 3rd engaging part 413 and the 4th engaging part 414, respectively. According to this, the third engaged portion 423 and the fourth engaged portion 424 are inserted into the hole-shaped third engaging portion 413 and the fourth engaging portion 414, respectively, and are locked, The movement of the outer plate member 22 and the closing member 23 in the left-right direction and the front-rear direction can be more effectively regulated.
