Description

【０００１】
【発明の属する技術分野】
本発明は、浴槽と周囲壁面との隙間を塞ぐ浴槽目地材に関するものである。
【０００２】
【従来の技術】
浴槽と周囲壁面に隙間があると、浴槽のあふれ水や、浴室清掃時の汚れた水などが、壁と浴槽の隙間にはいり、壁面、防水パンが汚れてしまう。これらの場所は、清掃用具が容易に届かないため、掃除がしづらいため、汚れが見えたり、悪臭の原因となる。
【０００３】
そこで従来の技術は、浴槽と壁の隙間を塞ぐ方法として、シリコン等の止水剤でコーキングを行っていたが、シリコンによるコーキングは施工に手間がかかる、熟練が必要である、充填後養生期間が必要、汚れやすい、カビが生える、シリコン自体が切れてしまう等の問題があった。
【０００４】
これらシリコンでの問題点を解決するために、浴槽隙間部材を用いて浴槽と壁の隙間を塞ぐ方法が案出しされた。例えば特開平１１−３３６２０８号や実開昭５７−１６３９０４号等である。
【０００５】
しかし、これらの方法では浴槽に目地をつけて設置するため、浴槽設置時に目地材または浴槽と壁が接触し、据え付けづらいという問題がある。また干渉を避けるために浴槽を小さくすると、浴槽と壁の隙間が大きくなるため、目地材の幅も太くなり外観が悪くなる。目地を交換する場合には、浴槽を取り外す必要があり大変である等の問題があった。
【０００６】
また浴槽設置後に取付けるものは、浴槽設置後目地を挿入するが、固定力が目地部と壁面との摩擦力に頼ったものであり、隙間のばらつきによっては固定力が発揮されない。浴槽が動いた場合、位置がずれるなどの問題があった。
【０００７】
【発明が解決しようとする課題】
本発明は上記の問題点に鑑みてなされたものであり、本発明の目的は、浴槽と周囲壁面との隙間の充填に手間がかからず、汚れにくく、また浴槽が設置しやすいように浴槽設置後に目地を取付け、さらに隙間のばらつきや、浴槽の動きにもずれない目地材を提供することにある。
【０００８】
【課題を解決するための手段】
上記目的を達成するために請求項１は、防水パンと浴槽と壁またはカウンターからなる浴室ユニットにおいて、浴槽据付け後に浴槽と壁またはカウンターの隙間に差込み固定する目地材であって、前記目地材は壁またはカウンターと浴槽とを水密的に塞ぐ上面部と、壁またはカウンターと浴槽との間に差し込まれる差込部を有し、前記差込部は、前記上面部から垂下する垂下部と、前記垂下部より浴槽内方に傾斜する傾斜部とを備え、前記傾斜部の先端に浴槽リム下端部と係合する係合部を備えたことを特徴としたので、浴槽据付後に目地を取付けるため、浴槽設置時に目地部と壁が干渉しないため浴槽設置が容易にできる。
【０００９】
また浴槽据付時に壁面と干渉するものがないため、浴槽と壁面の隙間を小さくできる。そのため目地意匠部の幅を小さくすることができ意匠面で優れている。
【００１０】
目地を交換する場合、目地の係合部をはずすことで目地が取れるため、あらかじめ浴槽に目地を取付ける場合に比べ浴槽をはずす手間など、大幅に作業の手間は軽減される。差込部に係合部を備えることで摩擦力や粘着による固定方法に比べ高い固定力を得ることができる。そのため浴槽が多少動いても追従性があり、充分な止水性を得ることができる。
【００１１】
浴槽と壁面の隙間がばらついた場合であっても、差込部に傾斜部があり、その傾斜部が隙間に応じて変形することで確実に浴槽リム下端に係合することで、目地と浴槽との固定力が得られるため、浴槽やユニットバスの寸法のばらつきや、浴槽の多少の動きもしくは変形による隙間のばらつきがあっても、追従することができ、目地がはずれることや、止水性を失うことがない。
【００１２】
浴槽と壁の隙間がばらついた場合、垂下部側面のヒレにより常に目地の意匠部が壁面へと押し付けられるため、寸法ばらつきや変形等により隙間がばらついても、壁面との止水性を得ることができる。
【００１３】
【発明の実施の形態】
本発明を図面に示した実施の形態に基づき更に詳細に説明する。図１は本発明に係わる浴槽目地材の断面図の一例である。材質は、ポリプロピレン、塩化ビニール、ＡＢＳ、またはエラストマー等の熱可塑性樹脂からなり、押出し成形方法によって成形される。目地全体を上記の硬質樹脂、もしくは硬度９０度程度の半硬質樹脂、もしくは７ａ上面部と、７ｅヒレ部のみ、エラストマー等の軟質素材で他の部分は上記硬質樹脂の組み合わせ等、複数の素材もしくは硬度の素材で成形することができる。
【００１４】
図１において７目地材は、７ａ上面部と、７ａ上面部より下方に伸びる７ｂ差込部からなる。７ａ上面部は２浴槽側へ下向きに傾斜した形状となっている。さらに７ｂ差込部は、７ｄ垂下部と７ｄ垂下部の側面に設けられた７ｅヒレ部と、７ｄ垂下部の下端から２浴槽側へと傾斜した７ｆ傾斜部からなる。７ｆ傾斜部の先端には突起形状の７ｃ係合部がある。
【００１５】
７目地材の使用状態を図２に示す。５浴室ユニットにおいて、２浴槽と、３壁や４カウンターとの６隙間に使用する。７目地材を適切な長さに切断し、６隙間上部より７目地材を挿入する。７目地材は、７ｃ係合部が、２ｂ浴槽リム下端部に係合し、２浴槽に固定される。一旦係合されると、２浴槽が動いても７目地材も同調して動くため外れることがない。
【００１６】
７目地材の使用状態の断面図を図３に示す。７ａ上面部は、２浴槽と、３壁面に接することで止水を行う。３壁面は４カウンターでも良い。７ａ上面部の下端から７ｃ係合部までの距離を、２ａ浴槽リム部の高さよりもわずかに小さくすることにより、７目地材を６隙間に差し込む際は、７ａ上面部の下端から７ｃ係合部までの距離が２ａ浴槽リム部の高さに合うように、７ａ上面部及び７ｂ差込み部が変形することで、２ａ浴槽リムの下端部に係合し、７ａ上面部及び７ｂ差込み部変形の反発力により７ａ上面部は２浴槽におしつけられることで、良好な止水性を得ることができる。
また７ｅヒレ部が２浴槽に接することで、７ａ上面部を３壁面へ押し付けるため良好な止水性を得ることができる。
【００１７】
２浴槽や、４カウンターの寸法のばらつき等で、６隙間がばらついても、７ａ上面部と７ｆ傾斜部が変形することで対応できる。図４（イ）のように６隙間が最大となる場合に、７ｃ係合部が２ｂ浴槽リム下端部と係合できるように７ｆ傾斜部の形状を設定している。また、７ｅヒレ部が２ａ浴槽リムと接する形状に設定している。
なお７ｂ差込部は、円弧形状や直線と円弧を組み合わせた形状でも良い。
図４（ロ）のように６隙間が小さくなった場合、７ｆ傾斜部は２ａ浴槽リム部に押されることで変形し、かつ７ａ上面部も変形することで、２ｂ浴槽リム下端部に係合し固定力を発揮し、７ａ上面部は２浴槽と良好な止水性を得ることができる。また７ｅヒレ部も２ａ浴槽リム部に押されることで変形し、７ａ上面部を３壁面へ押し付けるため良好な止水性を得ることができる。
【００１８】
図５（イ）及び図５（ロ）に示すように、２ａ浴槽リム部の高さ方向の寸法がばらついた場合においても、７ａ上面部の下端から７ｃ係合部までの距離が２ａ浴槽リム部の高さに合うように、７ａ上面部と７ｆ傾斜部が変形することで、７ｃ係合部が２ｂ浴槽リム部下端部に係合し、固定力及び止水性を得ることができる。
【００１９】
図６に７目地材と８コーナーピースの設置例を示す。２ｃ浴槽短辺側と２ｄ浴槽長辺側の突き当たり部に８コーナーピースを設置し、８コーナーピースを７目地材にかぶせることで、７目地材の長さのばらつきや２ｃ浴槽短辺部、２ｄ浴槽長辺部の寸法のばらつきを吸収し、隙間ができないように設置する事ができる。
【００２０】
２ｃ浴槽短辺部に設置する７目地材の端部を切り欠き変形させ、２浴槽に沿う形状に加工することで、見栄よくおさめる事ができる。図７に９目地材端部加工品実施例を示す。
【００２１】
図７に浴槽目地固定方法の他の例を示す。１０目地材は１０ａ上面部と１０ｂ垂下部と１０ｂ垂下部の下端に１０ｃ係合部を持ち、３壁に１２ビスで取付けられた１１目地固定材にて１０目地材を係合し固定する。この場合、６隙間のばらつきは１０ａ上面部の幅で対応する。２ａ浴槽リムの高さのばらつきは、１０ｃ係合部と11目地固定材の係合箇所を複数持つことで対応する。１０目地材または11目地固定材のどちらかのみ、係合箇所を複数にしても良い。

BACKGROUND OF THE INVENTION
The present invention relates to a bathtub joint material that closes a gap between a bathtub and a surrounding wall surface.
[0002]
[Prior art]
If there is a gap between the bathtub and the surrounding wall, overflow water from the bathtub or dirty water when cleaning the bathroom will enter the gap between the wall and the bathtub, and the wall and waterproof pan will become dirty. In these places, the cleaning tool cannot be easily reached, so that it is difficult to clean, and therefore, dirt can be seen and a bad odor can be caused.
[0003]
Therefore, the conventional technology used caulking with a water-stopping agent such as silicon as a method of closing the gap between the bathtub and the wall, but caulking with silicon requires time and labor for construction, and a curing period after filling. However, there are problems such as being necessary to be dirty, easily becoming moldy, growing mold, and cutting silicon itself.
[0004]
In order to solve these problems with silicon, a method of closing the gap between the bathtub and the wall using a bathtub gap member has been devised. For example, Japanese Patent Application Laid-Open No. 11-336208 and Japanese Utility Model Laid-Open No. 57-163904.
[0005]
However, in these methods, since the bathtub is jointed and installed, there is a problem that the joint material or the bathtub and the wall are in contact with each other when the bathtub is installed, and it is difficult to install. If the bathtub is made small to avoid interference, the gap between the bathtub and the wall becomes large, so that the width of the joint material becomes thick and the appearance deteriorates. When exchanging joints, there was a problem that it was difficult to remove the bathtub.
[0006]
Moreover, although what is attached after bathtub installation inserts a joint after bathtub installation, fixing force relies on the frictional force of a joint part and a wall surface, and fixing force is not exhibited by the dispersion | variation in a clearance gap. When the bathtub moved, there was a problem that the position shifted.
[0007]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to save time and trouble in filling the gap between the bathtub and the surrounding wall surface. A joint is attached after installation, and a joint material that does not deviate from gap variations and bathtub movements is provided.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, claim 1 is a bathroom unit comprising a waterproof pan, a bathtub, and a wall or a counter, and is a joint material that is inserted into a gap between the bathtub and the wall or the counter after the bathtub is installed, and the joint material is An upper surface portion for watertightly closing the wall or the counter and the bathtub, and an insertion portion inserted between the wall or the counter and the bathtub, the insertion portion being a hanging portion depending from the upper surface portion; An inclined portion that inclines inward from the hanging portion, and an engagement portion that engages with the lower end of the bathtub rim at the tip of the inclined portion. Since the joint portion and the wall do not interfere with each other when the bathtub is installed, the bathtub can be easily installed.
[0009]
Moreover, since there is nothing which interferes with a wall surface at the time of bathtub installation, the clearance gap between a bathtub and a wall surface can be made small. Therefore, the width of the joint design portion can be reduced, and the design is excellent.
[0010]
When exchanging joints, the joints can be removed by removing the joints of the joints. Therefore, the labor of removing the bathtub is greatly reduced as compared with the case where the joint is previously attached to the bathtub. By providing the engaging portion in the insertion portion, a high fixing force can be obtained as compared with a fixing method using frictional force or adhesion. Therefore, even if the bathtub moves somewhat, there is followability and sufficient water stoppage can be obtained.
[0011]
Even when the gap between the bathtub and the wall surface varies, there is an inclined portion in the insertion portion, and the inclined portion is deformed according to the gap, so that the lower end of the bathtub rim is reliably engaged with the joint rim and the bathtub. Can be followed, even if there is a variation in the dimensions of the bathtub or unit bath, or a variation in the gap due to some movement or deformation of the bathtub. Never lose.
[0012]
When the gap between the bathtub and the wall varies, the joints of the joints are always pressed against the wall surface by the fins on the side of the hanging part, so that even if the gap varies due to dimensional variation or deformation, water-stopping with the wall surface can be obtained. it can.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in more detail based on embodiments shown in the drawings. FIG. 1 is an example of a sectional view of a bathtub joint material according to the present invention. The material is made of a thermoplastic resin such as polypropylene, vinyl chloride, ABS, or elastomer, and is formed by an extrusion method. The entire joint is made of the above-mentioned hard resin, or a semi-hard resin having a hardness of about 90 degrees, or only the upper surface portion of the 7a and the 7e fin portion. It can be molded with a material of hardness.
[0014]
In FIG. 1, the 7 joint material includes a 7a upper surface portion and a 7b insertion portion extending downward from the 7a upper surface portion. The upper surface portion of 7a is inclined downward toward the two bathtubs. Further, the 7b insertion portion is composed of a 7d hanging portion and a 7e fin portion provided on the side surfaces of the 7d hanging portion, and a 7f inclined portion inclined from the lower end of the 7d hanging portion toward the two bathtubs. There is a protruding 7c engaging portion at the tip of the 7f inclined portion.
[0015]
The use state of the 7 joint material is shown in FIG. In 5 bathroom units, it is used for 6 gaps between 2 bathtubs, 3 walls and 4 counters. Cut the 7 joint material to an appropriate length, and insert the 7 joint material from the upper part of the 6 gap. As for 7 joint material, 7c engaging part engages with 2b bathtub rim lower end part, and is fixed to 2 bathtubs. Once engaged, even if the 2 bathtubs move, the 7 joint material also moves synchronously so that it does not come off.
[0016]
A cross-sectional view of the 7-joint material in use is shown in FIG. 7a upper surface part stops water by contacting 2 bathtubs and 3 wall surfaces. The 3 walls may be 4 counters. The distance from the lower end of the upper surface portion of the 7a to the engaging portion of the 7c is slightly smaller than the height of the 2a bathtub rim portion. 7a upper surface part and 7b insertion part are deformed so that the distance to the part matches the height of 2a bathtub rim part, and engages with the lower end part of 2a bathtub rim, 7a upper surface part and 7b insertion part deformation By repelling the upper surface of the 7a in the two bathtubs, good water stoppage can be obtained.
Moreover, since a 7e fin part contacts 2 bathtubs, since the 7a upper surface part is pressed on 3 wall surfaces, favorable water stoppage can be obtained.
[0017]
Even if 6 gaps vary due to variations in dimensions of 2 bathtubs or 4 counters, etc., this can be dealt with by deforming the upper surface portion of 7a and the inclined portion of 7f. The shape of the 7f inclined portion is set so that the 7c engaging portion can be engaged with the lower end portion of the 2b bathtub rim when the six gaps are maximized as shown in FIG. Moreover, the 7e fin part is set to the shape which touches 2a bathtub rim.
The 7b insertion portion may have an arc shape or a combination of a straight line and an arc.
When 6 gaps become smaller as shown in FIG. 4 (b), the 7f inclined portion is deformed by being pushed by the 2a bathtub rim portion, and the upper surface portion of the 7a is also deformed to engage the lower end portion of the 2b bathtub rim. Then, the fixing force is exerted, and the upper surface portion of the 7a can obtain two bathtubs and good water stoppage. Further, the 7e fin portion is also deformed by being pushed by the 2a bathtub rim portion, and the upper surface portion of the 7a is pressed against the three wall surfaces, so that a good water stoppage can be obtained.
[0018]
As shown in FIGS. 5 (a) and 5 (b), even when the height dimension of the 2a bathtub rim portion varies, the distance from the lower end of the upper surface portion of the 7a to the 7c engaging portion is 2a bathtub rim. By deforming the upper surface portion of the 7a and the inclined portion of the 7f so as to match the height of the portion, the 7c engaging portion is engaged with the lower end portion of the 2b bathtub rim portion, and a fixing force and water stoppage can be obtained.
[0019]
FIG. 6 shows an installation example of 7 joint materials and 8 corner pieces. By installing 8 corner pieces at the end of the 2c bathtub short side and 2d bathtub long side, and covering the 8 corner pieces with the 7 joint material, the length variation of the 7 joint material and the 2c bathtub short side part, 2d It can be installed so as to absorb the variation in the dimension of the long side of the bathtub and not to have a gap.
[0020]
The end of the 7 joint material installed in the short side part of the 2c bathtub is cut out and deformed, and processed into a shape along the 2 bathtub, so that it can be comfortably held. FIG. 7 shows an example of a 9 joint end product.
[0021]
FIG. 7 shows another example of the bathtub joint fixing method. The 10 joint material has a 10c engaging portion at the lower end of the upper surface portion of the 10a, the 10b hanging portion, and the 10b hanging portion, and the 10 joint material is engaged and fixed by an 11 joint fixing material attached to 3 walls with 12 screws. In this case, the variation of the six gaps corresponds to the width of the upper surface portion 10a. The variation in the height of the 2a bathtub rim is dealt with by having a plurality of engaging portions of the 10c engaging portion and the 11 joint fixing material. Only one of the 10 joint material and the 11 joint fixing material may have a plurality of engaging portions.
