The joint tool 1 according to this embodiment is used by being attached to a bathroom 10 as shown in FIG. In the bathroom 10, a bathtub 12 is provided between the left and right wall surfaces 11 </ b> A and 11 </ b> B, and a window 13 is provided on the back wall surface 11 </ b> C side of the bathtub 12. On the left wall side, a door 14 for entering and exiting the bathroom 10 is provided. A mirror 15 is attached to the right wall surface 11B, a storage portion 16 is attached next to the mirror 15, a lighting fixture 17 is attached above the mirror 15, and a counter 18 is provided below the mirror 15. A faucet 19 is provided. The bathroom 10 is provided with a shower or the like, but is not shown.

  The bathtub flange 12 </ b> A has a front hanging part 12 </ b> B that is suspended from the front end of the upper surface so as to face the washing area, and an apron 21 is attached between the lower end of the front hanging part 12 </ b> B and the bath bed 20. A gap is formed between the bathtub flange 12A and the left wall surface 11A, the right wall surface 11B, and the back wall surface 11C, and the joint fitting 1 is attached to the gap.

  The joint tool 1 includes a joint material 30 and a mooring member 60, as shown in FIG. The joint material 30 includes a cover part 31 and an insertion part 32 as shown in FIGS. The cover portion 31 has a triangular cross section, and the triangular cross section includes a substantially horizontal back surface 31A, a surface 31B inclined upward from the inner end of the substantially horizontal back surface, and an outer surface end from the substantially horizontal back surface outer end. It is surrounded by the inclined back surface 31C inclined upward.

  The joint material 30 has a band shape as shown in FIG. 2, and not only fills the gap between the upper surface of the bathtub flange 12A and the wall surface, but also fills the gap between the front hanging portion 12B of the bathtub flange 12A and the wall surface. It is. The joint material 30 is preferably bent in the lateral direction at one end side in the longitudinal direction of the insertion portion 32. Therefore, a plurality of notches 34 are preferably provided in the insertion portion 32 on the inner side in the longitudinal direction from the end portion 33 of the joint material 30. That is, it is preferable that a plurality of notches 34 are provided in the insertion portion 32 corresponding to the vicinity of the boundary between the upper surface of the bathtub flange 12A and the front hanging portion 12B.

  The insertion part 32 has elasticity, is formed in a strip shape as shown in FIG. 2, and hangs down from, for example, the inclined back surface 31 </ b> C of the cover part 31. As shown in FIG. 3, the insertion portion 32 includes a base portion 32 </ b> A having a linear cross section and a leg portion 32 </ b> B that curves and extends from the tip of the base portion 32 </ b> A. The leg portion 32 </ b> B is curved so that the tip thereof is located outside the joint material 30. For this reason, when the insertion part 32 is inserted in the clearance gap between the bathtub flange 12A and a wall surface, the front-end | tip of the leg part 32B can contact | abut to a wall surface, and the base part 32A can be pressed on the bathtub flange 12A. Moreover, as shown in FIG. 6, the insertion part 32 inserted in the clearance gap between the front drooping part 12B and a wall surface is comprised only by the base 32A. That is, the curved leg portion 32B is not provided. For this reason, it is possible to prevent the base portion 32A and the apron 21 from interfering with the joint material 30 being inserted into the gap between the front surface and the wall surface of the front hanging portion 12B. Here, the outer side of the joint material 30 refers to the wall surface side in a state where the joint material 30 is inserted between the bathtub flange 12A and the wall surface, and the inner side refers to the bathtub flange side.

  In the base portion 32A, the insertion portion 32 has a protrusion 32C protruding from the flange-side inner surface, an elastic fin portion 32D extending obliquely downward on the flange-side inner surface of the base portion 32A, and an obliquely upward extension on the wall-side outer surface of the base portion 32A. Two elastic fin portions 32E and 32F. Any of the elastic fin portions 32D, 32E, and 32F is thinner toward the base portion 32A and becomes thinner toward the tip. The inner elastic fin portion 32D is shorter than the two outer elastic fin portions 32E and 32F.

  The elastic fin portion 32D and the elastic fin portion 32E are provided at substantially the same height at a position facing each other across the base portion 32A, and the protrusion 32C and the elastic fin portion 32F are provided at a position substantially facing each other across the base portion 32A. The protrusion 32C and the elastic fins 32D, 32E, 32F are all provided at the same height in the longitudinal direction. If comprised in this way, the joint material 30 can be easily manufactured by extrusion molding.

  The joint material 30 is formed of a thermoplastic resin, and is manufactured by two-color molding with the cover portion 31 and the elastic fin portions 32D, 32E, and 32F being a soft material and the base portion 32A being a hard material. As the soft material, methyl methacrylate is used, and as the hard material, a copolymer synthetic resin of acrylonitrile, butadiene (Butadiene) and styrene (Styrene), an acrylic resin, or the like is used. In addition, the joint material 30 may be formed of an olefin elastomer or a styrene elastomer.

  At the end portion 33 in the longitudinal direction of the insertion portion 32, the base portion 32A is provided with an insertion portion 35 for engaging one end portion of an anchoring member 60 such as a tape. The insertion part 35 is preferably an endless long hole as shown in FIG. 2, and is preferably provided between the protrusion 32C and the elastic fin part 32D as shown in the figure. An elastic adhesive portion 50 is formed by applying and hardening an elastic adhesive to the concave portion formed by the protrusion 32C and the elastic fin portion 32D. Since the elastic adhesive can be held by applying the elastic adhesive to the recess, the elastic adhesive layer can bond the base portion 32A and the front hanging portion 12B with the joint material 30 attached. Further, by providing the elastic fin portions 32E and 32F, the base portion 32A can be pressed against the bathtub flange 12A by the elastic force of the elastic fin portions 32E and 32F, and the water stoppage between the base portion 32A and the wall surface can be further improved. The insertion portion 35 may have a hook shape opened at the tip of the base portion 32 </ b> A, or may open at an end portion of the joint material 30. The mooring member 60 may be changed as appropriate according to the type of the mooring member 60.

  A tape material 40 is used for the mooring member 60. As shown in FIG. 5, the tape material 40 preferably includes a piece portion 42 that protrudes from one side of a rectangular sticking portion 41. The piece part 42 is good in the trapezoid shape from which the width | variety becomes narrow toward the front-end | tip from the sticking part 41. FIG. The piece 42 is inserted into the long hole as the insertion part 35 shown in FIG. Easy to do. Since the sticking part 41 is stuck on a wall surface or a bathtub, it is preferable that the sticking part 41 has a large area. The back surface of the tape material 40 has an adhesive layer, and a release paper is attached.

The tape material 40 is made of a material such as a metal foil such as an aluminum foil in consideration of durability and resistance to tearing, and an adhesive layer is provided on the back surface of the metal foil. As long as the elastic adhesive part 50 is fixed at least between the base part 32A and the front hanging part 12B of the bathtub flange 12A, the tape material 40 and the wall surface or the bathtub need only adhere to each other. What is necessary is just to have the adhesive force of 1 thru | or 0.3 N / mm < ² > or more.

  By using the tape material 40 as the mooring member 60, the joint material 30, the tape material 40 and the elastic bonding portion 50 constituting the joint device 1 can be easily removed, and the apron 21 is removed to replace piping and various devices. Can be easily maintained.

  As shown in FIG. 1, a method of attaching joint materials to the gaps between the bathtub 12 and the left wall surface 11 </ b> A, the bathtub 12 and the right wall surface 11 </ b> B, and the bathtub 12 and the rear wall surface 11 </ b> C will be described.

  First, the length of each gap to which the joint material is attached is measured, and each joint material is cut to the measured length. At this time, as shown in FIG. 6, the end portion of the joint material 30 is cut so that the end face of the bathtub flange 12 </ b> A and the end face of the joint material 30 are located on substantially the same plane. At that time, a joint material in which a notch or an insertion portion is not provided in the gap between the bathtub 12 and the inner wall surface 11C is used, and between the bathtub 12 and the left wall surface 11A, between the bathtub 12 and the right wall surface 11B. In each gap, a joint material 30 as shown in FIGS. 2 to 4 in which a notch portion 34 and an insertion portion 35 are provided in the insertion portion 32 is used. The opposite ends of the two joint materials 30 provided with the insertion portions 35 are welded and integrated with both ends of the joint material provided with no notches and insertion portions. The joint material thus integrated is opposed to the gap between the bathtub flange 12A and the left wall surface 11A, the back wall surface 11C, and the right wall surface 11B.

  Next, as shown in FIG. 6, the joint material 30 is inserted into the gap between the bathtub flange 12A and the right wall surface 11B. When the insertion portion 32 is inserted with the inner surface of the insertion portion 32 facing the bathtub flange 12A, the elastic adhesive is applied to the protrusion 32C and the elastic fin portion 32D either before or after the lower end of the base portion 32A is inserted into the gap. Apply to the recess between and without any gap. At that time, an elastic adhesive is also applied to the concave portion between the protrusion 32C on the base portion 32A side and the elastic fin portion 32D. Thereafter, the base portion 32A is sequentially inserted into the gap from the back side of the bathtub 12 toward the washing area.

  After the joint material 30 is inserted into the upper surface of the bathtub flange 12A and the right wall surface 11B, the joint material 30 is bent in the short direction along the notch 34 of the joint material 30 as shown in FIG. An insertion portion 35 is provided closer to the end portion 33 than the notch portion 34, and a piece 42 of the tape material 40 is inserted into the insertion portion 35 and folded back, and the pieces 42 are bonded to each other. Therefore, the base portion 32A on the end portion 33 side of the joint material 30 is inserted between the front hanging portion 12B of the bathtub flange 12A and the right wall surface 11B. After that, it is confirmed that the covering portion 31 is in close contact with the gap surface between the front hanging portion 12B and the right wall surface 11B, and the release paper on the back surface of the attaching portion 41 of the tape material 40 is peeled off. Is attached to the right wall surface 11B, for example.

  Here, the depth width of the recess formed in the inner surface of the base portion 32A of the joint material 30 is set to be shorter than the thickness width of the bathtub flange 12A. Therefore, in a state where the joint material 30 is attached between the bathtub flange 12A and the right wall surface 11B, a substantially sealed space is formed between the recess and the bathtub flange 12A, and the elastic bonding portion 50 is formed in the space. The bathtub flange 12 </ b> A and the insertion portion 32 are bonded and fixed with an elastic bonding portion 50 interposed therebetween. For this reason, even if the bathtub 12 is displaced in the vertical direction, the joint material 30 follows the bathtub 12 or the elastic adhesive portion 50 is deformed, so that the joint material 30 does not rise from the gap. Similarly, the joint material 30 is inserted into the gap between the left wall surface 11 </ b> A and the bathtub flange 12 </ b> A to provide the elastic bonding portion 50.

  By this series of operations, the insertion portion 32 of the joint material 30 is arranged between the front hanging portion 12B hanging down so as to face the washing place in the bathtub flange 12A, and the end portion 33 of the insertion portion 32 is arranged. A piece 42 of the tape material 40 as the mooring member 60 is inserted into the insertion portion 35, and the sticking portion 41 of the tape material 40 is stuck to the wall surface. Therefore, the end portion 33 of the joint material 30 is bent, and the insertion portion inserted between the front hanging portion 12B and the wall surface is pulled by the wall surface with the mooring member 60 interposed therebetween. Therefore, since the joint material 30 has flexibility, the bent portion of the joint material 30 does not return to the original linear state due to the restoring force, and the joint material 30 does not leave the front drooping portion 12B and can be prevented from floating. Thus, one end of the tape material 40 is engaged with the insertion portion 32 of the joint material 30, and the other end of the tape material 40 is fixed to the wall of the bathroom, so that the joint member 30 is bent by the mooring member 60. State is maintained.

  Moreover, the elastic adhesive part 50 is formed when an operator apply | coats an elastic adhesive agent to the recessed part of 32 A of bases, and hardens the substantially sealed space between the base part 32A and the bathtub flange 12A with an elastic adhesive agent. Although it takes at least several hours to several days until the state of the elastic bonding portion 50 is stabilized, even if the joint material 30 is attached by bending the joint material 30 along the front hanging portion 12B of the bathtub flange 12A, the flexibility of the joint material 30 is not limited. The floating from the bathtub flange 12A due to the property can be prevented. Therefore, the gap between the bathtub flange 12A and the wall surface of the bathroom can be efficiently jointed.

The embodiment of the present invention is not limited to the above-described example, but includes a form that is appropriately changed.
In the above description, the other end portion of the tape material 40 as the mooring member 60 is fixed to the wall of the bathtub, but the other end side of the tape material 40 may be fixed to the outer peripheral surface of the bathtub.

  The mooring member 60 is not limited to the tape material 40, and may be a wire member such as a wire or a string. In this case, if a claw portion such as a hook is provided on one end side of the linear member, the insertion portion 35 of the insertion portion 32 of the joint material 30 is not formed into a long hole shape as shown in FIG. It is good also as a shape where a nail | claw part is easily hooked on the insertion part 32. FIG.
