上部便座ケーシング410は略楕円形の環状の着座面411の後部に起曲部412が連続して形成されている。着座面411は内周部より外周部が高い傾斜を有する上方に凸の曲面を成している。   The upper toilet seat casing 410 has a curved portion 412 formed continuously at the rear portion of a substantially elliptical annular seating surface 411. The seating surface 411 forms an upwardly convex curved surface having an inclination in which the outer peripheral portion is higher than the inner peripheral portion.

下部便座ケーシング420は主としてPP(ポリプロピレン)樹脂を使用した成型品であり、平面形状が上部便座ケーシング410と略同形状の本体部421と、本体部421の両側後方に斜め上方に突出した腕部422で構成されている。   The lower toilet seat casing 420 is a molded product mainly using PP (polypropylene) resin, and has a main body portion 421 whose planar shape is substantially the same as that of the upper toilet seat casing 410, and an arm portion that projects obliquely upward to the rear of both sides of the main body portion 421. 422.

下部便座ケーシング420の外周と内周には上方に起立した外周縁420aと内周縁420bが形成されており、外周縁420aの先端には溶着リブ420cが一体に形成されており、内周縁420bの先端には溶着リブ420dが一体に形成されている。これらの溶着リブ420c、420dは下部便座ケーシング420と接合部材430を結合するときに振動溶着機により溶融して溶着させるものである。   An outer peripheral edge 420a and an inner peripheral edge 420b are formed on the outer periphery and the inner periphery of the lower toilet seat casing 420, and a welding rib 420c is integrally formed at the tip of the outer peripheral edge 420a. A welding rib 420d is integrally formed at the tip. These welding ribs 420c and 420d are melted and welded by a vibration welding machine when the lower toilet seat casing 420 and the joining member 430 are coupled.

接合部材430は主としてPP樹脂を使用した成型品であり、上部便座ケーシング410の外周縁410aに対応する外周接合部材431と、上部便座ケーシング410の内周縁410cに対応する内周接合部材432の2つの部材で構成されている。   The joining member 430 is a molded product mainly using PP resin. The outer joint member 431 corresponding to the outer peripheral edge 410a of the upper toilet seat casing 410 and the inner peripheral joint member 432 corresponding to the inner peripheral edge 410c of the upper toilet seat casing 410 are two. It consists of two members.

便座ヒータ450は、前部の一部が切り取られた略馬蹄状に形成されている。便座ヒータ450は、アルミニウムからなる2枚の金属箔の間に、線状ヒータを蛇行させて配設して構成されている。特に着座面411に着座した使用者の大腿部と臀部が快適に加熱されるように場所によって密度を変えて配設してある。   The toilet seat heater 450 is formed in a substantially horseshoe shape with a part of the front portion cut off. The toilet seat heater 450 is configured by meandering a linear heater between two metal foils made of aluminum. In particular, the user's thighs and buttocks seated on the seating surface 411 are arranged with different densities depending on the location so that they can be comfortably heated.

図4は上部便座ケーシング410と接合部材430の要部の断面図であり、図5は上部便座ケーシング410と接合部材430を取り付けた状態を下方から見た斜視図である。   4 is a cross-sectional view of the main parts of the upper toilet seat casing 410 and the joining member 430, and FIG. 5 is a perspective view of the state in which the upper toilet seat casing 410 and the joining member 430 are attached as viewed from below.

図4に示すように上部便座ケーシング410の外周縁410aを折り曲げて形成した接合縁410bには、接合縁410bの一部を切り起こして形成した複数の固定爪413が間隔をあけて配置されている。また固定爪413の略中央には円形の貫通孔413aが形成されている。   As shown in FIG. 4, a plurality of fixed claws 413 formed by cutting and raising a part of the joint edge 410b are arranged at intervals on the joint edge 410b formed by bending the outer peripheral edge 410a of the upper toilet seat casing 410. Yes. A circular through-hole 413a is formed in the approximate center of the fixed claw 413.

外周接合部材431は略楕円形の環状であり、断面は略L字型に形成されている。上部便座ケーシング410の接合縁410bに当接する上部には平坦部431aが形成されており、平坦部431aの外周側には下方に突出した接合リブ431bが全周に亘り形成されている。接合リブ431bの高さは下部便座ケーシング420の溶着リブ420cの高さより低い寸法になっている。   The outer periphery joining member 431 has a substantially elliptical annular shape, and has a substantially L-shaped cross section. A flat portion 431a is formed on the upper portion of the upper toilet seat casing 410 that contacts the joint edge 410b, and a joint rib 431b protruding downward is formed on the entire outer periphery of the flat portion 431a. The height of the joining rib 431b is smaller than the height of the welding rib 420c of the lower toilet seat casing 420.

平坦部431aには、上部便座ケーシング410の固定爪413に対応する位置に固定孔433が間隔をあけて複数個形成されている。固定孔433は上部の入り口部分は固定爪413と略同寸法で固定爪413が挿入可能な形状に形成されているが、奥の方は固定爪413より小さい寸法に形成されており、また固定孔433の深さも固定爪413の高さより浅く、通常の状態では固定孔433に固定爪413を挿入できない構成となっている。   A plurality of fixing holes 433 are formed in the flat portion 431a at intervals corresponding to the fixing claws 413 of the upper toilet seat casing 410. The fixing hole 433 has an entrance portion at the upper part that is substantially the same size as the fixing claw 413 and can be inserted into the fixing claw 413, but the depth is smaller than the fixing claw 413 and is fixed. The depth of the hole 433 is also shallower than the height of the fixed claw 413, and the fixed claw 413 cannot be inserted into the fixed hole 433 in a normal state.

上部便座ケーシング410の固定爪413を外周接合部材431の固定孔433の入り口部分に当接させた状態で、固定爪413を電磁誘導加熱装置で加熱して昇温させながら、外周接合部材431を上部便座ケーシング410に押し付けると、固定爪413の熱により外周接合部材431の固定孔433の周辺の樹脂が溶融して、固定爪413の全体が外周接合部材431の固定孔433の奥まで完全に挿入される。また、溶融した樹脂は固定爪413の貫通孔413aを貫通して接合される。   While the fixed claw 413 of the upper toilet seat casing 410 is in contact with the entrance portion of the fixed hole 433 of the outer peripheral joint member 431, the outer peripheral joint member 431 is moved while heating the fixed claws 413 with an electromagnetic induction heating device. When pressed against the upper toilet seat casing 410, the resin around the fixing hole 433 of the outer joint member 431 is melted by the heat of the fixing claws 413, and the entire fixing claws 413 are completely penetrated to the inner side of the fixing hole 433 of the outer joint member 431. Inserted. Further, the molten resin is bonded through the through hole 413a of the fixing claw 413.

このような状態で、電磁誘導加熱装置の加熱を停止させると、溶融した樹脂は固化して、上部便座ケーシング410の接合縁410bと外周接合部材431の平坦部431aは密着させた状態で固定することができる。特に溶融した樹脂の一部は固定爪413貫通孔413a貫通した状態で固化するため、上部便座ケーシング410と外周接合部材431を強固に固定することができる。   When the heating of the electromagnetic induction heating device is stopped in such a state, the molten resin is solidified, and the joint edge 410b of the upper toilet seat casing 410 and the flat portion 431a of the outer peripheral joint member 431 are fixed in a state of being in close contact with each other. be able to. In particular, since a part of the molten resin is solidified in a state where it passes through the fixing claw 413 through-hole 413a, the upper toilet seat casing 410 and the outer joint member 431 can be firmly fixed.

同様に、上部便座ケーシング410の内周縁410cを折り曲げて形成した接合縁410dには、接合縁410dの一部を切り起こして形成した複数の固定爪413が間隔を空けて配置されており、固定爪413の略中央には円形の貫通孔413aが形成されている。   Similarly, on the joint edge 410d formed by bending the inner peripheral edge 410c of the upper toilet seat casing 410, a plurality of fixing claws 413 formed by cutting and raising a part of the joint edge 410d are arranged at intervals. A circular through-hole 413 a is formed at the approximate center of the claw 413.

内周接合部材432は略楕円形の環状であり、断面は略L字型に形成されている。上部便座ケーシング410の接合縁410dに当接する上部には平坦部432aが形成されており、平坦部432aの内周側には下方に突出した接合リブ432bが全周に亘り形成されている。接合リブ432bの高さは下部便座ケーシング420の溶着リブ420dの高さより低い寸法になっている。   The inner peripheral joining member 432 has a substantially elliptical annular shape, and has a substantially L-shaped cross section. A flat portion 432a is formed on the upper portion of the upper toilet seat casing 410 that contacts the joint edge 410d, and a joint rib 432b that protrudes downward is formed on the entire inner periphery of the flat portion 432a. The height of the joining rib 432b is smaller than the height of the welding rib 420d of the lower toilet seat casing 420.

外周接合部材431と同様に、平坦部432aには、上部便座ケーシング410の固定爪413に対応する位置に固定孔433が間隔をあけて複数個形成されている。固定孔433は上部の入り口部分は固定爪413を略同寸法で固定爪413が挿入可能な形状に形成されているが、奥の方は固定爪413より小さい寸法に形成されており、また固定孔433の深さも固定爪413を挿入できる深より浅く、通常の状態では固定孔433に固定爪413を挿入できない構成となっている。   Similar to the outer peripheral joint member 431, a plurality of fixing holes 433 are formed in the flat portion 432 a at positions corresponding to the fixing claws 413 of the upper toilet seat casing 410 at intervals. The fixing hole 433 is formed in a shape in which the fixing claw 413 can be inserted into the upper entrance portion so that the fixing claw 413 is substantially the same size, but the depth is smaller than the fixing claw 413 and is fixed. The depth of the hole 433 is also shallower than the depth at which the fixed claw 413 can be inserted, and the fixed claw 413 cannot be inserted into the fixed hole 433 in a normal state.

上部便座ケーシング410の固定爪413を内周接合部材432の固定孔433の入り
口部分に当接させた状態で、固定爪413を電磁誘導加熱装置で加熱して昇温させながら、内周接合部材432を上部便座ケーシング410に押し付けると、固定爪413の熱により内周接合部材432の固定孔433の周辺の樹脂が溶融して、固定爪413の全体が内周接合部材432の固定孔433の奥まで完全に挿入される。また、溶融した樹脂は固定爪413の貫通孔413aを貫通して接合される。
While the fixed claw 413 of the upper toilet seat casing 410 is in contact with the entrance portion of the fixed hole 433 of the inner peripheral joint member 432, the inner peripheral joint member is heated while heating the fixed claw 413 with an electromagnetic induction heating device. When 432 is pressed against the upper toilet seat casing 410, the resin around the fixing hole 433 of the inner peripheral joining member 432 is melted by the heat of the fixing pawl 413, and the entire fixing pawl 413 is formed in the fixing hole 433 of the inner peripheral joining member 432. It is completely inserted to the back. Further, the molten resin is bonded through the through hole 413a of the fixing claw 413.

このような状態で、電磁誘導加熱装置の加熱を停止させると、溶融した樹脂は固化して、上部便座ケーシング410の接合縁410dと内周接合部材432の平坦部432aは密着させた状態で固定することができる。特に溶融した樹脂の一部は固定爪413貫通孔413a貫通した状態で固化するため、上部便座ケーシング410と内周接合部材432を強固に固定することができる。   When the heating of the electromagnetic induction heating device is stopped in such a state, the molten resin is solidified, and the joint edge 410d of the upper toilet seat casing 410 and the flat portion 432a of the inner peripheral joint member 432 are fixed in a state of being in close contact with each other. can do. In particular, since a part of the molten resin is solidified in a state where it passes through the fixing claw 413 through-hole 413a, the upper toilet seat casing 410 and the inner peripheral joining member 432 can be firmly fixed.

<3>ラミネートフィルムの構成
図6はラミネートフィルム440の断面の構成を示す模式図である。
<3> Configuration of Laminate Film FIG. 6 is a schematic diagram showing a cross-sectional configuration of the laminate film 440.

ラミネートフィルム440はフィルム基材としてPP(ポリプロピレン)樹脂を使用して3層構造で形成している。第1の層である接着剤層440aは、材質としてはアクリル系接着剤を用い、厚さが約50μmである。接着剤層440aに積層される第2の層であるフィルム基材440bは、材質としてPPを用い、厚さが100μm〜150μmである。第2の層であるフィルム基材440bの上に積層される表面層440cは、材質としてはPPを用い、厚さ50μm〜100μmである。フィルム基材440bと表面層440cとは合計の厚さが約200μmになるように形成されている。   The laminate film 440 is formed in a three-layer structure using PP (polypropylene) resin as a film substrate. The adhesive layer 440a as the first layer uses an acrylic adhesive as a material and has a thickness of about 50 μm. The film base 440b, which is the second layer laminated on the adhesive layer 440a, uses PP as a material and has a thickness of 100 μm to 150 μm. The surface layer 440c laminated on the film base 440b as the second layer uses PP as a material and has a thickness of 50 μm to 100 μm. The film base 440b and the surface layer 440c are formed to have a total thickness of about 200 μm.

接着剤層440aとフィルム基材440bは接着剤層440aの接着力で固定され、フィルム基材440bと表面層440cは、熱を加えることによりそれぞれを軟化させ固着させている。   The adhesive layer 440a and the film base 440b are fixed by the adhesive force of the adhesive layer 440a, and the film base 440b and the surface layer 440c are softened and fixed by applying heat.

ラミネートフィルム440は、第1の層である接着剤層440aにより上部便座ケーシング410および接合部材430に接着され、第2の層であるフィルム基材440bは、意匠性を持たせる層であり、単色或いは複数色の印刷や様々な柄を施すことが可能である。第3の層である表面層440cは、フィルム基材440bへの傷つき防止やトイレで使用される洗剤により印刷部の劣化を防止のための保護層であるとともに、透明材料を用いることにより、意匠に深みを与えより一層意匠性を向上させることができる。   The laminate film 440 is adhered to the upper toilet seat casing 410 and the joining member 430 by the adhesive layer 440a which is the first layer, and the film base material 440b which is the second layer is a layer having design properties, and is monochromatic. Alternatively, it is possible to perform printing of a plurality of colors and various patterns. The surface layer 440c, which is the third layer, is a protective layer for preventing damage to the film base 440b and preventing the printing portion from being deteriorated by a detergent used in the toilet, and by using a transparent material, The design can be further improved by adding depth.

これにより、上部便座ケーシング410の着座面411およびその後部の起曲部412は一体で形成されているラミネートフィルム440で覆われているために表面に化粧処理を施す必要がなく、また、上部便座ケーシング410と接合部材430の外周接合部401aおよび内周接合部401bもラミネートフィルム440で覆われるため、別途防水処理を施す必要がなくなり、上部便座ケーシング410の加工工程を削減することができるとともに、上部便座ケーシング410と接合部材430との組み立て工程も削減することができる。   As a result, the seating surface 411 of the upper toilet seat casing 410 and the bent portion 412 at the rear portion thereof are covered with the integrally formed laminate film 440, so that it is not necessary to apply cosmetic treatment to the surface, and the upper toilet seat Since the casing 410 and the outer peripheral joint portion 401a and the inner peripheral joint portion 401b of the joining member 430 are also covered with the laminate film 440, it is not necessary to perform waterproofing separately, and the processing steps of the upper toilet seat casing 410 can be reduced. The assembly process of the upper toilet seat casing 410 and the joining member 430 can also be reduced.

また、上部便座ケーシング410を主としてアルミニウム合金により形成することで、着座面411およびその後部の起曲部412の熱伝導性を向上することができ、上部便座ケーシング410の裏面に粘着された便座ヒータ450で、短時間のうちに着座面411およびその後部の起曲部412の温度を昇温させることが可能となる。   Further, by forming the upper toilet seat casing 410 mainly from an aluminum alloy, the thermal conductivity of the seating surface 411 and the bent portion 412 at the rear thereof can be improved, and the toilet seat heater adhered to the back surface of the upper toilet seat casing 410 In 450, the temperature of the seating surface 411 and the bent portion 412 at the rear portion can be raised in a short time.

<4>ラミネートフィルムの固定方法
図7はラミネートフィルムの取り付け方法を示す模式図であり、図8はラミネートフィルム取り付け後の上部便座ケーシングと接合部材の結合体の断面図である。
<4> Method for Fixing Laminate Film FIG. 7 is a schematic view showing a method for attaching the laminate film, and FIG. 8 is a cross-sectional view of a combined body of the upper toilet seat casing and the joining member after the laminate film is attached.

ラミネートフィルム440は主にPP樹脂フィルムで形成されており、熱を加えることで容易に伸縮変形しやすくなる。   The laminate film 440 is mainly formed of a PP resin film, and is easily stretched and deformed by applying heat.

ラミネートフィルム440を上部便座ケーシング410と接合部材430の形状に沿い密着固定する方法としては、成型装置(図示せず)の中に図5に示すように上部便座ケーシング410と接合部材430を完全に覆う大きさのフラットなラミネートフィルム440を接着剤層440aが下面となるように配置する。ラミネートフィルム440の下方に上部便座ケーシング410と接合部材430の結合体を配置する。   As a method of tightly fixing the laminate film 440 along the shape of the upper toilet seat casing 410 and the joining member 430, as shown in FIG. 5, the upper toilet seat casing 410 and the joining member 430 are completely fixed in a molding apparatus (not shown). A flat laminate film 440 having a size to cover is arranged so that the adhesive layer 440a is on the lower surface. A combined body of the upper toilet seat casing 410 and the joining member 430 is disposed below the laminate film 440.

ラミネートフィルム440に熱を加えて容易に伸縮変形する状態にし、接着剤層440aを下面としたラミネートフィルム440の下方より上部便座ケーシング410と接合部材430の結合体を押し当てる。   Heat is applied to the laminate film 440 so that the laminate film 440 is easily stretched and deformed, and the combined body of the upper toilet seat casing 410 and the joining member 430 is pressed from below the laminate film 440 with the adhesive layer 440a as the lower surface.

これにより、ラミネートフィルム440は上部便座ケーシング410と接合部材430の結合体に沿って伸縮および変形し、上部便座ケーシング410の着座面411および後部の起曲部412と、上部便座ケーシング410と接合部材430との接合部および接合部材430の側面はラミネートフィルム440で覆われる。この状態で、成形装置(図示せず)の内部を真空状態にすることで、ラミネートフィルム440の外周端部440dと内周端部440eは接合部材430の下面まで回り込み、上部便座ケーシング410と接合部材430の結合体の形状に沿ったラミネートフィルム440は接着剤層440aにより接着固定される。   As a result, the laminate film 440 expands and contracts along the combined body of the upper toilet seat casing 410 and the joining member 430, and the seating surface 411 and the rear bent portion 412 of the upper toilet seat casing 410, the upper toilet seat casing 410, and the joining member. The bonding portion with 430 and the side surface of the bonding member 430 are covered with a laminate film 440. In this state, the inside of the molding apparatus (not shown) is evacuated, whereby the outer peripheral end 440d and the inner peripheral end 440e of the laminate film 440 wrap around to the lower surface of the joining member 430 and join the upper toilet seat casing 410. The laminate film 440 along the shape of the combined body of the members 430 is bonded and fixed by the adhesive layer 440a.

ラミネートフィルム440の接着固定後、ラミネートフィルム440の外周端部440dおよび内周端部440eは不要な部分を切除し、ラミネートフィルム440の外周端部440dが外周接合部材431の平坦部431aの下面を覆い、内周端部440eが内周接合部材432の平坦部432aの下面を覆うように所定の形状に仕上げる。   After bonding and fixing the laminate film 440, the outer peripheral end portion 440d and the inner peripheral end portion 440e of the laminate film 440 are removed, and the outer peripheral end portion 440d of the laminate film 440 covers the lower surface of the flat portion 431a of the outer peripheral bonding member 431. The inner peripheral end 440e is finished to a predetermined shape so as to cover the lower surface of the flat portion 432a of the inner peripheral joining member 432.

次に、切断加工を行ったラミネートフィルム440の外周端部440dと外周接合部材431の平坦部431aおよび内周端部440eと内周接合部材432の平坦部432aの複数個所を超音波溶着機により溶着する。これにより、ラミネートフィルム440は容易に剥離させることができない構造となる。   Next, an ultrasonic welder is used to cut the outer peripheral end 440d of the laminated film 440 that has been cut, the flat portion 431a of the outer peripheral bonding member 431, and the inner peripheral end 440e and the flat portion 432a of the inner peripheral bonding member 432 using an ultrasonic welding machine. Weld. Thereby, the laminate film 440 has a structure that cannot be easily peeled off.

The casings 420 are arranged to face each other, the welding ribs 420c on the outer peripheral edge 420a of the lower toilet seat casing 420 are brought into contact with predetermined positions on the flat portion 431a of the outer peripheral joining member 431, and the welding ribs 420d on the inner peripheral edge 420b are brought into contact with the inner peripheral joining member 432. The welding ribs 420c and 420d are melted by a vibration welding machine in a state in which the flat portion 432a is in contact with a predetermined position, and the lower toilet seat casing 420 is pressed against the combined body of the upper toilet seat casing 410 and the joining member 430, thereby joining. The tip ends of the welding ribs 420c and 420d higher than the height of the rib 431b are deformed. , Assembly of the joint member 430 and the lower toilet seat casing 420 seat 400 is welded and fixed to complete.

完成状態では、接合部材430の接合リブ431b、432dより高い溶着リブ420c、420dの先端部が溶融して押圧されることにより高さが低くなり、ラミネートフィルム440の外周端部440dおよび内周端部440eは接合部材430と下部便座ケー
シング420で狭持された状態となり、容易に剥離しない状態となる。
In the completed state, the tips of the welding ribs 420c and 420d higher than the joining ribs 431b and 432d of the joining member 430 are melted and pressed to reduce the height, and the outer peripheral end 440d and inner peripheral end of the laminate film 440 are reduced. The part 440e is sandwiched between the joining member 430 and the lower toilet seat casing 420, and is not easily peeled off.

上記のように、本実施の形態おける便座400は、ラミネートフィルム440で上部便座ケーシング410と接合部材430を覆い、接合部材430と下部便座ケーシングを溶着固定することにより、上部便座ケーシング410の化粧処理と上部便座ケーシング410と接合部材430の接合部の防水処理を同時に実施することができるとともに、接合部材430と下部便座ケーシング420を溶着固定することにより、接合部材430と下部便座ケーシング420の接合部の防水処理を行うことができ、結果的に便座400全体の防水処理を行うことができる。   As described above, the toilet seat 400 according to the present embodiment covers the upper toilet seat casing 410 and the joining member 430 with the laminate film 440, and welds and fixes the joining member 430 and the lower toilet seat casing, so that the cosmetic treatment of the upper toilet seat casing 410 is performed.
