Description

  The present invention relates to a bathtub joint material that closes a gap between a bathtub and a surrounding wall surface.

  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.

  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.

  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.

  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. Further, if the bathtub is made small in order to avoid interference, the gap between the bathtub and the wall becomes large, so 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.

  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.

  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. It is to provide a joint material that is attached to the joint after installation, and that does not deviate from variations in gaps or movement of the bathtub.

  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 One end of the wall or the counter vertical surface, the other end abuts on the top surface of the bathtub, and the wall or the counter and the bathtub are watertightly closed, and the insertion portion extends downward from the top surface. Since the insertion portion is provided with an engaging portion that engages with the lower end portion of the bathtub rim, and a fin portion that protrudes inward of the bathtub is provided on the side surface of the insertion portion, the joint is attached after the bathtub is installed. Therefore, since the joint portion and the wall do not interfere with each other when the bathtub is installed, the bathtub can be easily installed.

  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.

  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.

  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.

  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.

(B) Shows the usage condition when the bathtub rim height is low, (b) Shows the usage condition when the bathtub rim height is high An example of using a corner piece The example of the process shape of a joint edge part is shown. The other example of a joint is shown.

  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 a 7a upper surface portion and a 7e fin portion. It can be molded with a material of hardness.

  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.

  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.

A 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.

  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. In addition, 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.

  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.

  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.

  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.

  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.
