Description

この発明は、浴室内においてこの浴室内壁に沿って据え付けられる浴槽と、この浴室内壁との間の隙間を塞ぐために用いられるシール材の改良、およびその製造方法に関する。   The present invention relates to an improvement in a sealing material used to close a gap between a bathtub installed along the inner wall of the bathroom and the inner wall of the bathroom, and a method for manufacturing the same.

軟質樹脂製の頂部と、硬質樹脂製の基部とを備え、この基部を浴槽と浴室内壁との間隙に基部を押し込ませて頂部によってこの間隙を塞ぐようにした目地材がある。（特許文献１参照）   There is a joint material that includes a top portion made of a soft resin and a base portion made of a hard resin, and the base portion is pushed into the gap between the bathtub and the inner wall of the bathroom so that the gap is closed by the top portion. (See Patent Document 1)

しかるに、かかる目地材にあっては、直線的な浴槽の辺部の目地施工はできても、浴槽のコーナー部の目地施工はできない。このため、浴槽のコーナー部においては、このコーナー部の形状に倣った別の目地材を用意せざるを得なかった。また、この別の目地材は辺部の目地材と重ね代をとって取り付けるか、これをとらなければ両者の間に別途目地施工せざるを得なかった。このため、両者の表面を美しく連ねさせ難く、また、経時的に両者の接合箇所に汚れなどが付着し難く、さらには、経時的に両者の風合いが変化し一体感が損なわれるといった不具合があった。
特開２００４−３５７９０３号公報 However, in such joint materials, joints can be applied to the corners of the bathtub even if the joints can be applied to the sides of the straight bathtub. For this reason, in the corner part of the bathtub, another joint material following the shape of the corner part had to be prepared. Moreover, this other joint material had to be attached to the joint material on the side portion in an overlapping manner, or if this was not taken, a separate joint construction had to be performed between the two. For this reason, it is difficult to make the surfaces of the two beautifully connected, and it is difficult for dirt or the like to adhere to the joints of the two over time, and further, the feeling of unity is lost due to the change in the texture of the two over time. It was.
JP 2004-357903 A

この発明が解決しようとする主たる問題点は、この種の浴室内壁と浴槽上縁面との間の隙間のシール材が、浴槽のコーナー部とこのコーナー部を挟んで隣り合う両辺部をそれぞれ、経時的にも意匠性を高く維持できる態様で、同時に塞ぐことができるようにする点にある。   The main problem to be solved by the present invention is that the seal material of the gap between this type of bathroom inner wall and the upper edge of the bathtub has a corner portion of the bathtub and both sides adjacent to the corner portion, It is the point which can be blocked simultaneously in the aspect which can maintain a design property highly also with time.

前記課題を達成するために、この発明にあっては、シール材を、浴室内壁と、浴槽上縁面におけるコーナー部を挟んで隣り合う一方の辺部の外縁との間の辺シール体の一端と、
浴室内壁と、浴槽上縁面における前記コーナー部を挟んで隣り合う他方の辺部の外縁との間の辺シール体の一端とを、
これら辺シール体をインサートとしたインサート成形によって形成させた、浴室内壁と浴槽上縁面における前記コーナー部の外縁との間の隅シール体を介して一体に接合させてなり、
少なくとも二つの前記辺シール体と一つの隅シール体とを備えてなるものとした。 In order to achieve the above-mentioned object, in the present invention, the sealing material includes one end of the side seal body between the inner wall of the bathroom and the outer edge of one side that is adjacent to the corner portion of the upper edge of the bathtub. When,
One end of the side seal body between the inner wall of the bathroom and the outer edge of the other side adjacent to the corner on the upper edge of the bathtub,
Formed by insert molding using these side seal bodies as inserts, and integrally joined via a corner seal body between the bathroom inner wall and the outer edge of the corner portion at the upper edge of the bathtub,
At least two side seal bodies and one corner seal body are provided.

かかるシール材によれば、浴室内壁と浴槽上縁面との間の隙間を、浴槽上縁面のコーナー部と、このコーナー部を挟んで隣り合う辺部とに亘って同時に塞ぐことができる。シール材は、辺シール体の表面と隅シール体の表面とに段差が生じないように、また、辺シール体の一端と隅シール体の接合端縁とをシール材の表側において一体化させることができ、両シール体を別体とした場合の両シール体の接合部への汚れの付着などの不具合を生じさせることがない。   According to such a sealing material, the gap between the bathroom inner wall and the bathtub upper edge surface can be simultaneously closed across the corner portion of the bathtub upper edge surface and the adjacent side portions with the corner portion interposed therebetween. The sealing material shall be integrated with one end of the side sealing body and the joining edge of the corner sealing body on the front side of the sealing material so that there is no step between the surface of the side sealing body and the surface of the corner sealing body. In the case where both seal bodies are separated, there is no problem such as adhesion of dirt to the joint portion of both seal bodies.

前記隅シール体を、軟質のプラスチックによって構成させておけば、この隅シール体を介して接合させ合わされている辺シール体同士のなす角度ないし位置はシール材の設置が済むまでは固定的ではないものにでき、その設置作業における取り回しなどを容易なものとすることができる。   If the corner seal body is made of soft plastic, the angle or position between the side seal bodies joined together via the corner seal body is not fixed until the sealing material is installed. It can be made easy, and handling in the installation work can be made easy.

この場合さらに前記辺シール体を、隅シール体と同一の軟質のプラスチックによって構成させておけば、両者の間の風合いを経時的にも維持させることができる。   In this case, if the side seal body is made of the same soft plastic as the corner seal body, the texture between the two can be maintained over time.

前記隅シール体の外縁が、辺シール体の外縁に沿った仮想の直線よりも外側に位置されるようにしておけば、アールを持った浴槽上端面のコーナー部とエッジ状をなす浴室内壁の内隅との間を適切に塞ぐことができる。   If the outer edge of the corner seal body is positioned outside the imaginary straight line along the outer edge of the side seal body, the corner of the upper end surface of the bathtub having a rounded shape and the edge of the bathroom inner wall forming an edge shape The space between the inner corners can be properly closed.

前記辺シール体の一端側の裏面を隅シール体によって覆うようにして隅シール体を形成させておけば、両者の表面側においては段差が生じないように両者を一体化させることができる。   If the corner seal body is formed so that the back surface on one end side of the side seal body is covered with the corner seal body, the both sides can be integrated so that no step is generated on the surface side of both.

これらのシール材は、押し出し成形により得られた辺シール体を浴槽上縁面の辺部の長さに合った長さに成形した後に、この辺シール体をインサートとした射出成形によって隅シール体を形成させることで、容易かつ適切に構成させることができる。   These sealing materials are obtained by molding a side seal body obtained by extrusion molding into a length that matches the length of the side portion of the upper edge of the bathtub, and then performing corner molding by injection molding using this side seal body as an insert. By forming, it can be configured easily and appropriately.

この発明にかかるシール材によれば、浴室内壁と浴槽のコーナー部との間の隙間および浴室内壁とこのコーナー部を挟んで隣り合う両辺部との間の隙間を、経時的にも意匠性を高く維持できる状態で、同時に塞ぐことができる。   According to the sealing material of the present invention, the gap between the bathroom inner wall and the corner portion of the bathtub and the gap between the bathroom inner wall and both side portions adjacent to each other across the corner portion can be designed over time. It can be closed at the same time while maintaining a high level.

以下、図１〜図６に基づいて、この発明を実施するための最良の形態について説明する。   Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.

なお、ここで図１は、実施の形態にかかるシール材Ｍの使用状態を辺シール体１の打ち込み箇所において断面にして、また、図２〜図６はそれぞれかかるシール材Ｍを表しており、特に図２は浴槽上縁面Ｐａの外縁Ｐｂを想像線で表しながら、これに倣うように構成されたシール材Ｍを平面視の状態として示している。   Here, FIG. 1 is a cross-sectional view of the usage state of the sealing material M according to the embodiment at the driving position of the side sealing body 1, and FIGS. 2 to 6 show the sealing material M, respectively. In particular, FIG. 2 shows the sealing material M configured to follow the outer edge Pb of the bathtub upper edge Pa as an imaginary line in a plan view.

この実施の形態にかかるシール材Ｍは、浴室内においてこの浴室内壁Ｗに沿って据え付けられる浴槽Ｐと、この浴室内壁Ｗとの間の隙間Ｓを塞ぐために用いられるものである。   The sealing material M according to this embodiment is used for closing a gap S between the bathtub P installed along the bathroom inner wall W and the bathroom inner wall W in the bathroom.

かかる浴槽Ｐとしては、典型的には、平面視の状態において、浴槽上縁面Ｐａの外縁Ｐｂの輪郭形状を略長方形状としたものが予定される。また、かかるシール材Ｍは、典型的には、このように構成された浴槽Ｐの浴槽上縁面Ｐａにおけるコーナー部Ｐｃを挟んで隣り合う二つの辺部Ｐｄ、Ｐｄをそれぞれ浴室内壁Ｗに沿わせて据え付けられる浴槽Ｐの前記隙間Ｓ、あるいは三つの辺部Ｐｄ、Ｐｄ、Ｐｄをそれぞれ浴室内壁Ｗに沿わせて据え付けられる浴槽Ｐの前記隙間Ｓを塞ぐために用いられる。かかるシール材Ｍは、浴槽上縁面Ｐａのコーナー部Ｐｃの外縁Ｐｂと浴室内壁Ｗとの間の隙間Ｓ、およびこのコーナー部Ｐｃを挟んで隣り合う辺部Ｐｄの外縁Ｐｂと浴室内壁Ｗとの間の隙間Ｓの双方を、同時に塞ぐ浴槽上縁面Ｐａの外縁Ｐｂに倣うように形成された単一のシール材Ｍである。   As such a bathtub P, typically, the one in which the outline shape of the outer edge Pb of the bathtub upper edge surface Pa is substantially rectangular in a plan view is planned. The sealing material M typically has two side portions Pd and Pd adjacent to each other along the bathroom inner wall W across the corner portion Pc of the bathtub upper edge surface Pa of the bathtub P thus configured. It is used for closing the gap S of the bathtub P installed along the bathroom inner wall W with the gap S of the bathtub P installed in accordance with the three sides Pd, Pd, Pd. The sealing material M includes a gap S between the outer edge Pb of the corner portion Pc of the bathtub upper edge surface Pa and the bathroom inner wall W, and the outer edge Pb of the side portion Pd adjacent to the corner portion Pc and the bathroom inner wall W. It is the single sealing material M formed so that both the clearance gaps S may be followed and the outer edge Pb of the bathtub upper edge surface Pa which closes simultaneously.

すなわち、かかるシール材Ｍは、少なくとも二つの辺シール体１、1と、一つの隅シール体２とを備えてなるものである。   That is, the sealing material M includes at least two side sealing bodies 1 and 1 and one corner sealing body 2.

浴槽Ｐが、一つのコーナー部Ｐｃを挟んで隣り合う二つの辺部Ｐｄ、Ｐｄを浴室内壁Ｗに接しさせるようにして据え付けられる場合には、これに対するシール材Ｍは二つの辺シール体１、1と一つの隅シール体２とから構成される。   When the bathtub P is installed so that two side portions Pd and Pd adjacent to each other with the one corner portion Pc interposed therebetween are in contact with the bathroom inner wall W, the sealing material M for the side portions Pd and Pd is the two side seal bodies 1 and 2. 1 and one corner seal body 2.

また、浴槽Ｐが、三つの辺部Ｐｄ、Ｐｄ、Ｐｄを浴室内壁Ｗに接しさせるようにして据え付けられる場合には、これに対するシール材Ｍは三つの辺シール体１、１、１と二つの隅シール体２、２とから構成される。   Further, when the bathtub P is installed so that the three side portions Pd, Pd, and Pd are in contact with the bathroom inner wall W, the sealing material M corresponding thereto is composed of three side seal bodies 1, 1, 1 and 2. It is comprised from the corner seal bodies 2 and 2.

辺シール体１は、浴室内壁Ｗと、浴槽上縁面Ｐａにおけるコーナー部Ｐｃ間にある辺部Ｐｄの外縁Ｐｂとの間の隙間Ｓを塞ぐように構成される。かかる辺部Ｐｄの外縁Ｐｂは直線状をなし、したがって、辺シール体１も直線状をなすように構成される。（図２）   The side seal body 1 is configured to close the gap S between the bathroom inner wall W and the outer edge Pb of the side portion Pd between the corner portions Pc on the bathtub upper edge surface Pa. The outer edge Pb of the side portion Pd is linear, and thus the side seal body 1 is also configured to be linear. (Figure 2)

図示の例では、かかる辺シール体１は、板状をなすように構成されている。また、かかる辺シール体１は板状をなす取り付け脚部１０を備えている。取り付け脚部１０は辺シール体１の裏面１ｂであってこの辺シール体１の外縁１ｃと内縁１ｄとの間となる箇所に上端を一体に連接させて下方に突き出すように形成されている。辺シール体１の表面１ａおよび裏面１ｂはいずれもその内縁１ｄ側を下とし外縁１ｃ側を上とするように傾斜している。取り付け脚部１０は垂直方向に沿うように下方に延びている。取り付け脚部１０の下端であってその内面１０ａ（浴槽Ｐの外面に向けられる面）側には掛合面１０ｃを上方に向けた掛合爪１０ｂが形成されている。この掛合爪１０ｂの下部は下方に向かうに連れてこの掛合爪１０ｂの突き出し寸法を次第に小さくする傾斜面１０ｄとなっている。辺シール体１の内縁１ｄ側の裏面１ｂとこの掛合面１０ｃとの間のピッチは、浴槽上縁面Ｐａとこの浴槽上縁面Ｐａの外縁Ｐｂから下方に垂直に下がる垂れ出し部Ｐｅ（しばしばフランジと称される。）の下端との間のピッチと略等しいか、これよりやや小さくなるようになっている。（図１）また、取り付け脚部１０の内面１０ａであって掛合面１０ｃと辺シール体１との間には、上下方向に間隔を開けて、二条の弾性リップ１０ｅが形成されている。それぞれの弾性リップ１０ｅはいずれも取り付け脚部１０の内面からその基部を下にし先端を上にするようにして傾斜状に突き出している。図示の例では、上側に位置される弾性リップ１０ｅの突き出し寸法が下側に位置される弾性リップ１０ｅの突き出し寸法よりも大きくなっている。また、閉塞対象となる前記隙間Ｓの巾よりも、辺シール体１の内縁１ｄと外縁１ｃとの間の水平方向の寸法が大きく、また、この隙間Ｓの巾よりも、弾性リップ１０ｅの先端と辺シール体１の外縁１ｃとの間の水平方向の寸法が大きくなるようになっている。   In the illustrated example, the side seal body 1 is configured to have a plate shape. Further, the side seal body 1 includes a mounting leg portion 10 having a plate shape. The mounting leg portion 10 is formed so as to protrude downward with the upper end integrally connected to the back surface 1b of the side seal body 1 and between the outer edge 1c and the inner edge 1d of the side seal body 1. Both the front surface 1a and the back surface 1b of the side seal body 1 are inclined so that the inner edge 1d side is the lower side and the outer edge 1c side is the upper side. The mounting leg 10 extends downward along the vertical direction. On the lower end of the mounting leg 10 and on the inner surface 10a (surface facing the outer surface of the bathtub P), a hooking claw 10b with the hooking surface 10c facing upward is formed. The lower portion of the hooking claw 10b is an inclined surface 10d that gradually decreases the protruding dimension of the hooking claw 10b as it goes downward. The pitch between the back surface 1b on the inner edge 1d side of the side seal body 1 and the engagement surface 10c is a drooping portion Pe (often lowered vertically from the bath upper edge surface Pa and the outer edge Pb of the bath upper edge surface Pa (often The pitch between the lower end and the lower end of the flange is substantially equal to or slightly smaller than the pitch. (FIG. 1) Further, two elastic lips 10e are formed on the inner surface 10a of the mounting leg 10 between the engagement surface 10c and the side seal body 1 with a space in the vertical direction. Each elastic lip 10e protrudes in an inclined manner from the inner surface of the mounting leg 10 so that its base is down and its tip is up. In the illustrated example, the protruding dimension of the elastic lip 10e positioned on the upper side is larger than the protruding dimension of the elastic lip 10e positioned on the lower side. Further, the horizontal dimension between the inner edge 1d and the outer edge 1c of the side seal body 1 is larger than the width of the gap S to be closed, and the tip of the elastic lip 10e is larger than the width of the gap S. And the outer dimension 1c of the side seal body 1 are increased in the horizontal dimension.

かかる辺シール体１は、プラスチックの押し出し成形によって、断面を一様にした長尺体として得られる。取り付け脚部１０は比較的硬質のプラスチックによって構成され、辺シール体１と弾性リップ１０ｅはこれよりも軟質のプラスチックによって構成される。かかる押し出し成形において両プラスチックを同時に押し出すことで、辺シール体１は前記形状を備えたものとして一体に成形される。   Such a side seal body 1 is obtained as a long body having a uniform cross section by plastic extrusion. The mounting leg 10 is made of a relatively hard plastic, and the side seal body 1 and the elastic lip 10e are made of a softer plastic. By extruding both plastics simultaneously in such extrusion molding, the side seal body 1 is integrally molded as having the shape described above.

隅シール体２は、浴室内壁Ｗと浴槽上縁面Ｐａにおける前記コーナー部Ｐｃの外縁Ｐｂとの間の隙間Ｓを塞ぐように構成される。したがって、かかる隅シール体２の外縁２ａおよび内縁２ｂはこのコーナー部Ｐｃの外縁Ｐｂに倣って湾曲ないしは屈曲されている。（図２）   The corner seal body 2 is configured to close a gap S between the bathroom inner wall W and the outer edge Pb of the corner portion Pc in the bathtub upper edge surface Pa. Therefore, the outer edge 2a and the inner edge 2b of the corner seal body 2 are curved or bent following the outer edge Pb of the corner portion Pc. (Figure 2)

また、かかる隅シール体２は、浴室内壁Ｗと、浴槽上縁面Ｐａにおける前記コーナー部Ｐｃを挟んで隣り合う一方の辺部Ｐｄの外縁Ｐｂとの間の辺シール体１の一端１ｅと、
浴室内壁Ｗと、浴槽上縁面Ｐａにおける前記コーナー部Ｐｃを挟んで隣り合う他方の辺部Ｐｄの外縁Ｐｂとの間の辺シール体１の一端１ｅとを、
この隅シール体２を介して一体に接合させるように構成されている。（図２） Further, the corner seal body 2 has one end 1e of the side seal body 1 between the bathroom inner wall W and the outer edge Pb of one side portion Pd adjacent to the corner portion Pc on the bathtub upper edge surface Pa.
One end 1e of the side seal body 1 between the bathroom inner wall W and the outer edge Pb of the other side portion Pd adjacent to the corner portion Pc on the bathtub upper edge surface Pa,
The corner seal body 2 is configured to be integrally joined. (Figure 2)

図示の例では、かかる隅シール体２は、二つの辺シール体１、1を略直角に接合させるように構成されている。   In the illustrated example, the corner seal body 2 is configured to join the two side seal bodies 1 and 1 at substantially right angles.

かかる隅シール体２は、板状をなすように構成されており、辺シール体１の取り付け脚部１０に相当する部分を有していない。また、かかる隅シール体２は、軟質のプラスチックによって構成されている。   The corner seal body 2 is configured to have a plate shape and does not have a portion corresponding to the mounting leg portion 10 of the side seal body 1. The corner seal body 2 is made of a soft plastic.

かかる隅シール体２の表面２ｃは辺シール体１の表面１ａと略同面上に位置されている。すなわち、辺シール体１の一方の一端１ｅ縁と隅シール体２の一端縁２ｇとの間、および辺シール体１の他方の一端１ｅ縁と隅シール体２の他端縁２ｇとの間には、これらの表面１ａ、２ｃ側においては段差が生じないようになっている。   The surface 2c of the corner seal body 2 is positioned substantially on the same surface as the surface 1a of the side seal body 1. That is, between one end 1 e edge of the side seal body 1 and one end edge 2 g of the corner seal body 2 and between the other end 1 e edge of the side seal body 1 and the other end edge 2 g of the corner seal body 2. The steps 1a and 2c are free from steps.

一方、隅シール体２の裏面２ｄは辺シール体１の裏面１ｂよりも下方に張り出している。また、隅シール体２の裏面２ｄは、その内縁２ｂから辺シール体１の取り付け脚部１０の内面１０ａが位置される箇所までの間に亘る水平面部２ｅと、取り付け脚部１０の外面が位置される箇所と隅シール体２の外縁２ａが位置される箇所との間に亘る傾斜面部２ｆとを備えている。また、隅シール体２は、この水平面部２ｅと傾斜面部２ｆとを備えた延出部２ｈを、辺シール体１の一端１ｅ縁を越えて辺シール体１の裏面１ｂ側に入り込ませ、この延出部２ｈにおいて辺シール体１の一端１ｅ側の裏面に一体化している。すなわち、隅シール体２は、辺シール体１の一端１ｅ側の裏面１ｂを覆うようにして形成されている。   On the other hand, the back surface 2 d of the corner seal body 2 projects downward from the back surface 1 b of the side seal body 1. Further, the back surface 2d of the corner seal body 2 has the horizontal surface portion 2e extending from the inner edge 2b to the position where the inner surface 10a of the mounting leg portion 10 of the side sealing body 1 is positioned, and the outer surface of the mounting leg portion 10 positioned. And an inclined surface portion 2f extending between the portion where the outer edge 2a of the corner seal body 2 is located. Further, the corner seal body 2 causes the extending portion 2h provided with the horizontal surface portion 2e and the inclined surface portion 2f to enter the back surface 1b side of the side seal body 1 beyond the edge 1e of the side seal body 1, In the extension part 2h, it integrates with the back surface at the side of the one end 1e of the side seal body 1. FIG. That is, the corner seal body 2 is formed so as to cover the back surface 1b of the side seal body 1 on the one end 1e side.

また、隅シール体２の外縁２ａは、辺シール体１の外縁１ｃに沿った仮想の直線ｘよりも外側に位置されるようになっている。図示の例では、二箇所の前記延出部２ｈ、２ｈの間において隅シール体２は辺シール体１よりも幅広に構成されており、この間において隅シール体２の外縁２ａは仮想の直線ｘよりも外側に位置されている。この外縁２ａは湾曲状をなしている。これにより、この実施の形態にあっては、隅シール体２は、前記傾斜面部２ｆの先に外側水平面部２ｉをさらに備えている。（図２、図３）   Further, the outer edge 2 a of the corner seal body 2 is positioned outside the virtual straight line x along the outer edge 1 c of the side seal body 1. In the illustrated example, the corner seal body 2 is configured to be wider than the side seal body 1 between the two extending portions 2h and 2h, and the outer edge 2a of the corner seal body 2 is assumed to be an imaginary straight line x. It is located outside. The outer edge 2a is curved. Thereby, in this embodiment, the corner seal body 2 further includes an outer horizontal surface portion 2i at the tip of the inclined surface portion 2f. (Fig. 2, Fig. 3)

また、この実施の形態にあっては、隅シール体２の内縁２ｂも、辺シール体１の内縁１ｄに沿った仮想の直線ｙよりも内側に位置されるようになっている。（図２）   Further, in this embodiment, the inner edge 2b of the corner seal body 2 is also positioned inside the virtual straight line y along the inner edge 1d of the side seal body 1. (Figure 2)

そして、かかる隅シール体２は、前記辺シール体１をインサートとしたインサート成形によって形成されている。   The corner seal body 2 is formed by insert molding using the side seal body 1 as an insert.

かかるシール材Ｍによれば、浴室内壁Ｗと浴槽上縁面Ｐａとの間の隙間Ｓを、浴槽上縁面Ｐａのコーナー部Ｐｃと、このコーナー部Ｐｃを挟んで隣り合う辺部Ｐｂとに亘って同時に塞ぐことができる。シール材Ｍは、辺シール体１の表面１ａと隅シール体２の表面２ｃとに段差が生じないように、また、辺シール体１の一端１ｅと隅シール体２の端縁２ｇとをシール材Ｍの表側において一体化させることができ、両シール体１、２を別体とした場合の両シール体１、２の接合部への汚れの付着などの不具合を生じさせることがない。   According to the sealing material M, the gap S between the bathroom inner wall W and the bathtub upper edge surface Pa is divided into a corner portion Pc of the bathtub upper edge surface Pa and a side portion Pb adjacent to the corner portion Pc. It can be blocked simultaneously. The sealing material M seals one end 1e of the side seal body 1 and the edge 2g of the corner seal body 2 so that no step is generated between the surface 1a of the side seal body 1 and the surface 2c of the corner seal body 2. It can be integrated on the front side of the material M, and there is no problem such as adhesion of dirt to the joint portion of both seal bodies 1 and 2 when both seal bodies 1 and 2 are separated.

図示の例では、先ず、前記隙間Ｓに辺シール体１の取り付け脚部１０を上方から押し込むと、取り付け脚部１０は掛合爪１０ｂの傾斜面１０ｄを浴槽Ｐの垂れ出し部Ｐｅの外面に押し当てて外向きにやや弾性変形される。辺シール体１の裏面１ｂが浴槽上縁面Ｐａに接する位置まで取り付け脚部１０を押し込みきると取り付け脚部１０は弾発して掛合爪１０ｂの掛合面１０ｃが垂れ出し部Ｐｅの下端に掛合される。これにより、前記隙間Ｓは、浴槽上縁面Ｐａのコーナー部Ｐｃと、このコーナー部Ｐｃを挟んで隣り合う辺部Ｐｄとに亘って同時に塞がれる。かかる押し込みにより前記弾性リップ１０ｅは変形して垂れ出し部Ｐｅの外面に押しつけられ取り付け脚部１０の内面１０ａと垂れ出し部Ｐｅの外面との間を水密にシールする。   In the illustrated example, first, when the mounting leg 10 of the side seal body 1 is pushed into the gap S from above, the mounting leg 10 pushes the inclined surface 10d of the hooking claw 10b against the outer surface of the hanging part Pe of the bathtub P. It is slightly elastically deformed outwards when applied. When the mounting leg 10 is fully pushed into the position where the back surface 1b of the side seal body 1 is in contact with the bathtub upper edge surface Pa, the mounting leg 10 is repelled and the hooking surface 10c of the hooking claw 10b is hooked to the lower end of the drooping portion Pe. . Thereby, the said clearance gap S is simultaneously plugged over the corner part Pc of the bathtub upper edge surface Pa, and the side part Pd adjacent on both sides of this corner part Pc. By such pushing, the elastic lip 10e is deformed and pressed against the outer surface of the drooping portion Pe to seal the space between the inner surface 10a of the mounting leg portion 10 and the outer surface of the dripping portion Pe.

また、浴槽上縁面Ｐａのコーナー部Ｐｃにおいては、隙間Ｓは隅シール体２によって閉塞され、また、隅シール体２は軟質のプラスチックよりなり、しかも、その外縁２ａを辺シール体１の外縁１ｃよりも外側に位置させていることから、アールを持った浴槽上縁面Ｐａのコーナー部Ｐｃとエッジ状をなす浴室内壁Ｗの内隅（図示は省略する。）との間を適切に塞ぐことができる。   Further, in the corner portion Pc of the bathtub upper edge Pa, the gap S is closed by the corner seal body 2, and the corner seal body 2 is made of soft plastic, and the outer edge 2 a is used as the outer edge of the side seal body 1. Since it is located outside 1c, the space between the corner portion Pc of the bathtub upper edge surface Pa having a rounded shape and the inner corner (not shown) of the bathroom inner wall W having an edge shape is appropriately closed. be able to.

また、隅シール体２は軟質のプラスチックよりなることから、この隅シール体２を介して接合させ合わされている辺シール体１同士のなす角度ないし位置はシール材Ｍの設置が済むまでは固定的ではなく、その設置作業における取り回しなどが容易となる。かかる隅シール体２と辺シール体１とを同一の軟質のプラスチックから構成させておけば、両者の間の風合いを経時的にも維持させることができる。   Further, since the corner seal body 2 is made of soft plastic, the angle or position between the side seal bodies 1 joined together via the corner seal body 2 is fixed until the sealing material M is installed. Instead, it is easy to handle the installation work. If the corner seal body 2 and the side seal body 1 are made of the same soft plastic, the texture between them can be maintained over time.

かかるシール材Ｍは、押し出し成形により得られた辺シール体１を浴槽上縁面Ｐａの辺部Ｐｄの長さに合った長さに成形した後に、この辺シール体１をインサートとした射出成形によって隅シール体２を形成させることで、容易かつ適切に構成させることができる。   The sealing material M is formed by injection molding using the side seal body 1 as an insert after the side seal body 1 obtained by extrusion molding is molded to a length that matches the length of the side portion Pd of the bathtub upper edge surface Pa. By forming the corner seal body 2, it can be configured easily and appropriately.
