Description

  The present invention relates to a joint material for a bathtub which is attached to a gap between a bathtub and a wall surface portion or between a counter and a wall surface portion.

Conventionally, joint materials have been provided in the gaps formed between the bathtub installed in the bathroom and the wall surface of the bathroom, or between the counter installed in the bathtub and the wall surface. This prevents water from entering the gap (for example, Patent Document 1). The joint material includes an upper surface portion that closes the space between the wall surface portion and the bathtub, and an insertion portion that extends downward from the upper surface portion. It is comprised with the inclination part which inclines and inclines toward the bathroom side. And the fin part which protrudes in the bathroom side is formed in the drooping part, and the engaging part engaged with the lower end part of a bathtub rim is formed in the lower end part of the inclination part.

  However, the above-described conventional joint material is attached between the bathtub and the wall surface portion by engaging the engaging portion formed at the lower end portion of the engaging portion with the lower end portion of the bathtub rim. There exists a problem that a side part is formed in planar shape and cannot be used in the bathtub in which the bathtub rim is not provided. Moreover, since it is necessary to match the length of the joint material in the vertical direction with the length of the bathtub rim in the vertical direction, there is a problem that usable bathtubs are further limited. Furthermore, when the space | interval of a bathtub and a wall surface part is large, there exists a problem that a fin part cannot fully press-contact with a bathtub rim | limb, a joint material remove | deviates from a clearance gap, and sealing performance worsens.

  The present invention has been made to address the above-described problems, and an object of the present invention is to provide a joint material for a bathtub that can reliably seal a gap between the bathtub and the wall surface portion or the counter and the wall surface portion adjacent to the bathtub. It is.

  In order to achieve the above-described object, a structural feature of the joint material for bathtubs according to the present invention is a joint for bathtubs made of an elastic material attached to a gap between the bathtub and the wall surface part or between the counter and the wall surface part. A surface seal portion installed along the surface side portion of the bathtub or counter, and the bathtub or counter extending in a curved state in the width direction of the gap from the back surface of the surface seal portion toward the inside of the gap The surface sealing part seals between the bathtub and the wall surface part or between the counter and the wall surface part, and the insertion pressing part is connected to the bathtub. The surface sealing portion is fixed at an appropriate position by being pressed against both sides of the side surface and the wall surface portion or both sides of the counter and the wall surface portion.

  The joint material for bathtub of the present invention configured as described above is composed of a surface seal portion made of an elastic material and an insertion pressure contact portion, and the insertion pressure contact portion is formed from the surface side portion of the bathtub or the counter in the gap. The direction toward the back side is formed in a curved shape. Therefore, the insertion pressure contact portion is pressed and fixed to the surfaces on both sides in a state where the curved shape is pressed by the surfaces on both sides constituting the gap so as to approach a straight line. For this reason, the surface seal part also maintains the state fixed to the appropriate position along the predetermined part in the surface part of a bathtub or a counter. The surface portion of the bathtub or counter in this case is the upper surface edge of the bathtub or counter that faces the wall surface, the side surface of the bathtub or counter that faces the wall surface, or the like.

  In addition, since the insertion pressure contact portion is formed in a curved shape, the width of the insertion pressure contact portion is a length corresponding to the width of the clearance even if the width of the gap is slightly longer or shorter. become. For this reason, even if it is a case where the length between a bathtub and a wall surface part or between a counter and a wall surface part differs, it becomes possible to attach the joint material for bathtubs in an appropriate state. Furthermore, the joint material for bathtubs according to the present invention can be used for a bathtub without a bathtub rim. Further, the surface seal portion has a design function of improving the appearance as well as sealing the surface side portion of the gap in a good state by fixing the insertion pressure contact portion.

  In addition, another structural feature of the joint material for bathtubs according to the present invention is that the central side part between the surface seal part side part and the tip part in the insertion pressure contact part is biased to the side part of the bathtub or the counter. Thus, the curved shape of the insertion pressure contact portion is formed. According to this, at least the center side portion of the insertion pressure contact portion is in pressure contact with the side surface portion of the bathtub or the counter, and both end portions or the tip portion of the insertion pressure contact portion and the surface seal portion are in pressure contact with the wall surface portion. For this reason, three portions of the joint material for bathtubs come into pressure contact with both surfaces forming the gap, and the attachment of the joint material for bathtubs to the gap becomes strong.

  Further, another structural feature of the joint material for bathtubs according to the present invention is that an elastic fin portion is formed at a protruding portion in the curved shape of the insertion pressure contact portion. According to this, since an elastic fin part press-contacts to the surface which opposes, friction resistance becomes large and it becomes difficult to remove | join the joint material for bathtubs from a clearance gap further. Thereby, engagement with the joint material for bathtubs and both surfaces of a clearance gap becomes more reliable, and it can prevent that the joint material for bathtubs remove | deviates from a clearance gap.

  In addition, another structural feature of the joint material for bathtubs according to the present invention is that the surface seal part includes a bathtub close part in close contact with the bathtub or the counter and a wall close contact part in close contact with the wall part. It is in. According to this, the sealing performance by the surface seal portion is improved, and reliable water stop is possible.

  Still another structural feature of the joint material for bathtubs according to the present invention is that it is continuously attached to the gap between the bathtub and the wall surface part and between the counter and the wall surface part. According to this, the sealing performance when a counter is provided adjacent to the bathtub can be enhanced.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a bathroom 10 in which a joint material 20 as a joint material for bathtubs according to the present invention is installed. In this bathroom 10, a window 12 is provided on a wall surface portion 11 that partitions the inside of the bathroom 10 from the outdoors, and a bathtub 14 is installed on the floor 12 side of the window 12. And the side part of the right and left (front and rear in FIG. 1) of the bathtub 14 is facing the left wall surface panel 15a (refer FIG. 5) or the right wall surface panel 15b. Moreover, the counter 16 is provided in the part along the right wall surface panel 15b in the front side (right side in FIG. 1) of the bathtub 14. FIG. A mirror 17 and a storage shelf 18 are provided on the wall surface formed above the counter 16. Further, the height of the upper surface of the counter 16 is set to be substantially equal to the height of the upper surface portion 14 a of the bathtub 14.

  And the joint material 20 is attached to the clearance gap which arises in the boundary part with the left wall surface panel 15a, the wall surface part 11, and the right wall surface panel 15b in the edge of the upper surface part 14a of the bathtub 14 (the joint material on the left wall surface panel 15a side) 20 is not shown). The joint material 20 is also attached to a gap formed between the upper edge of the counter 16 and the right wall panel 15b. The joint material 20 is made of soft rubber having elasticity, and as shown in FIG. 2, the joint material 20 is formed in a band shape having a large cross-sectional shape.

  That is, the joint material 20 has a difference between the surface seal portion 21 having a substantially elliptical cross-sectional shape and the lower portion of the surface seal portion 21 in the state of FIG. It is comprised with the insertion pressure-contact part 22. FIG. The surface seal portion 21 is formed in a bathtub close portion 21a whose one end portion is positioned on the bathtub 14 side, and the other end portion is formed in a wall surface close portion 21b positioned on the wall surface side such as the left wall surface panel 15a. Yes. And the insertion press-contact part 22 is extended from the wall surface close part 21b side part in the lower part of the surface seal part 21. FIG. The insertion pressure contact portion 22 extends so as to incline toward the bathtub close portion 21a from the lower portion of the wall surface close contact portion 21b and extends so as to incline the lower side portion toward the wall close contact portion 21b side.

  In addition, an elastic fin portion 23 composed of one protrusion is formed at a substantially central portion in the vertical direction on the surface of the insertion press contact portion 22 on which the curve protrudes, and a pair of elastic fin portions 23 is formed below the elastic fin portion 23. The elastic fin part 24 which consists of this protrusion is formed. Moreover, the part installed in the corner | angular part of the left wall surface panel 15a and the wall surface part 11 in the insertion press-contact part 22, the part installed in the corner | angular part of the wall surface part 11 and the right wall surface panel 15b, and the upper surface part 14a of the bathtub 14 A triangular notch 25 as shown in FIG. 3 is provided in a portion installed at the corner between the side and the side.

  As a result, a surplus portion is not generated in the portion located on the inner corner side of the corner portion of the gap in the insertion pressure contact portion 22, and the joint material 20 can be more appropriately attached. Furthermore, when attaching the joint material 20 to the part pulled so that the edge part side (lower side) part of the insertion pressure-contact part 22 spreads, from the edge part of the insertion pressure-contact part 22 as shown in FIG. A linear cutting line 26 extending to the surface seal portion 21 side is provided. As a result, it is possible to prevent the insertion pressure contact portion 22 from being pulled due to an excessive force.

  Next, the joint material 20 configured in this way is used as a boundary between the bathtub 14 installed in the bathroom 10, the left wall panel 15a, the wall surface section 11, and the right wall panel 15b, and the counter 16 and the right wall panel. The case where it attaches to the clearance gap respectively produced in the boundary part between 15b is demonstrated. In this case, first, the length of the gap for attaching the joint material 20 is measured, and the joint material 20 is cut to the length of the measured value. And the notch part 25 and the cutting line 26 are provided in the part located in each corner | angular part of the clearance gap in the joint material 20 as needed. Next, the joint material 20 is attached by inserting the insertion pressure contact portion 22 into the gap sequentially from one end of the gap, for example, the front upper side portion of the bathtub 14 in the gap between the bathtub 14 and the left wall panel 15a. I do.

  At this time, as shown in FIG. 5, the insertion pressure contact portion 22 of the joint material 20 enters between the side surface portion of the bathtub 14 and the left wall surface panel 15a while deforming the curved portion so as to approach a straight line. Go. As a result, the surface seal portion 21 and the lower end portion of the insertion pressure contact portion 22 are pressed against the left wall surface panel 15a, and the substantially central portion of the insertion pressure contact portion 22 in the vertical direction is urged toward the bathtub 14 to be elastic. The fin portion 23 is in pressure contact with the side surface portion of the bathtub 14. At this time, the elastic fin portion 23 is crushed and closely contacts the side surface portion of the bathtub 14. Further, the distal end portion of the elastic fin portion 24 is also pressed against the side portion of the bathtub 14. As a result, the joint material 20 is fixed between the bathtub 14 and the left wall surface panel 15a.

  Further, by deforming the insertion pressure contact portion 22 so as to approach a straight line shape, the bathtub close portion 21a of the surface seal portion 21 is pressed against and closely contacts the upper surface portion 14a of the bathtub 14, and the wall surface close contact portion 21b is left. The space between the bathtub 14 and the left wall surface panel 15a is sealed in close contact with the wall surface panel 15a. This sealing state is maintained by fixing the joint material 20 between the bathtub 14 and the left wall surface panel 15a. Moreover, when the clearance gap between the bathtub 14 and the left wall surface panel 15a is narrower than the state shown in FIG. 5, the insertion press-contact part 22 makes a curved part into a linear form further from the state shown in FIG. While being deformed so as to approach, the elastic fin portion 24 is also crushed by the side surface portion of the bathtub 14 and closely contacts the side surface portion of the bathtub 14.

  Moreover, when the clearance gap between the bathtub 14 and the left wall surface panel 15a is wider than the state shown in FIG. 5, the insertion press-contact part 22 makes a curve larger than the state shown in FIG. 14 and the left wall surface panel 15a. When the joint material 20 is attached to the corner of the gap, the insertion pressure contact portion 22 is made to be in a natural state without extending or overlapping the joint pressure contact portion 22 side portion of the joint material 20. Insert into the part.

  In this case, both the insertion pressure contact portion 22 and the surface seal portion 21 of the joint material 20 attached to the corner portion are wrinkled and overlapped or pulled by the notch portion 25 provided in the insertion pressure contact portion 22. It can be attached in a proper state without any Similarly, the joint material 20 is attached to the gap generated between the bathtub 14, the wall surface portion 11 and the right wall panel 15b and the gap generated between the counter 16 and the right wall panel 15b.

  Thus, the joint material 20 according to the present embodiment includes the surface seal portion 21 that seals between the bathtub 14 and the wall surface such as the left wall surface panel 15a and between the counter 16 and the right wall surface panel 15b, and the inside of the gap. It is comprised by the insertion press-contact part 22 inserted in, and the center part of the insertion press-contact part 22 is formed in the curved shape so that it may protrude in the bathtub 14 side. Therefore, the insertion pressure contact portion 22 is fixed to the gap in a state where it is pressed against both sides of the gap. Thereby, the surface seal part 21 is fixed to an appropriate position along the edge or side surface of the bathtub 14 and maintains a good sealing property.

  Moreover, since the insertion pressure contact part 22 is formed in a curved shape, it is possible to attach the gap in the proper state even if the lengths in the width direction are different. Further, the joint material 20 can be used for a bathtub without a bathtub rim. In addition, since the elastic fin portions 23 and 24 are formed in the protruding portion of the insertion pressure contact portion 22 due to the curvature so that the elastic fin portions 23 and 24 are pressed against the opposing surfaces, the frictional resistance increases, and the joints The material 20 is firmly fixed to both sides of the gap. As a result, the joint between the joint material 20 and both surfaces of the gap becomes more reliable, and the joint material 20 can be prevented from coming out of the gap.

  Moreover, the joint material for bathtubs which concerns on this invention is not limited to embodiment mentioned above, It is possible to change suitably within the technical scope of this invention, and to implement. For example, the joint material for bathtubs may be formed of a spiral material formed from an elastic material.
