  As shown in FIGS. 3A to 3C, the insertion portion 28 on one end side in the longitudinal direction of the joint material 8 (the front side when mounted on the counter 3 as shown in FIG. 1) is a part thereof. Is cut out, and a folded portion 33 is provided in front of the cutout.

  The folded portion 33 can be folded downward and rearward about the narrow portion 34 that is narrowed by cutting out the insertion portion 28. The folded portion 33 is formed to be inclined downward toward the front tip side.

  The mounting of the joint material 8 to the counter 3 and its operation will be described in detail later. The joint material 8 is placed on the side wall 13 of the counter 3 from above, and the hook portion 29 of the main body portion 16 of the side wall 13 of the counter 3 is covered. The joint material 8 is attached to the gap between the small apron 6 and the counter 3 by hooking on the lower end 24 and hooking the hook portion 29 of the folded portion 33 on the tongue portion 17 of the counter 3 and mounting it on the counter 3. 27 closes the gap between the small apron 6 and the counter 3, and the fin 30 can stop water.

(Function)
The operation of the joint material 8 having the above-described configuration and the counter 3 to which the joint material 8 is mounted will be described below. As shown in FIG. 1, the counter material 3 is attached to the wall surface 4 so as to face the small apron 6, and then the joint material 8 is attached to the left side wall 13 of the counter 3.

  The process of mounting the joint material 8 on the left side wall 13 of the counter 3 will be described with reference to FIGS. As shown in FIG. 4A, the joint material 8 is positioned above the gap between the small apron 6 and the counter 3 so that the narrow portion 34 substantially corresponds to the upper edge 14 of the front surface 12 of the counter 3. . Then, as shown by the arrow in FIG. 4A, the insertion portion 28 is inserted into the gap between the small apron 6 and the counter 3 while covering the joint material 8 on the counter 3 from above.

  In this way, the hook portion 29 formed at the lower end of the insertion portion 28 of the joint material 8 is hooked on the lower end 24 of the main body portion 16 of the side wall 13 of the counter 3 as shown in FIG. Then, the joint member 8 is inserted until the upper surface portion 27 of the joint material 8 contacts the upper surface of the side wall 13 of the counter 3.

  In this state, the narrow portion 34 of the joint material 8 is brought into contact with the upper edge 14 of the front surface 12 of the counter 3, and as shown in FIG. In the center, it is bent downward and rearward along the inclined surface of the front end 19 of the tongue 17 of the counter 3.

  After being bent in this way, the hook portion 29 of the turn-back portion 33 is engaged with the notch 18 of the counter 3 located at the rear, thereby being hooked and fixed to the tongue portion 17. As a result, the joint material 8 is attached to the counter 3 and inserted into the gap between the small apron 6 and the counter 3 as shown in FIG. 5B, and the gap is closed.

  In this state, the left and right overhanging portions of the upper surface portion 27 of the joint material 8 are in contact with the small apron 6 and the top plate portion 11 of the counter 3, respectively, The fins abut against the small apron 6 and the side wall 13 of the counter 3. As a result, the gap between the small apron 6 and the counter 3 can be stopped by the joint material 8.

  As described above, the joint material 8 of the present invention requires a special fastening member such as a screw or a double-sided adhesive tape only by being inserted into the gap between the small apron 6 and the counter 3 and hooking the hook portion 29 on the counter 3. It can be easily mounted on the side wall 13 of the counter 3 to close the gap. Therefore, according to the present embodiment, the jointing operation of the joint material 8 becomes easier without requiring any skill as compared with the conventional caulking filling operation or the like.

  Incidentally, as described above, as shown in FIG. 2C, the length L of the perpendicular S from the front end 19 of the tongue portion 17 to the front edge 23 of the notch 18 of the counter 3 is the main body portion 16 of the side wall 13. The height H (substantially the same as the height of the joint material 8) is approximately the same length, but when the folded portion 33 of the joint material 8 is folded by forming the counter 3 in such a dimensional relationship, the hook 3 is hooked. The portion 29 can be hooked on the tongue portion 17 exactly.

  Then, after the folding portion 33 is bent, the hooking portion 29 of the folding portion 33 is engaged with the notch 18 of the counter 3 located at the rear and hooked on the tongue portion 17 to be fixed. Even if the joint material 8 is attached only to one side (the side wall 13 of the counter), the joint material 8 can be positioned and mounted at an appropriate position in the gap between the small apron 6 and the counter 3. It is suppressed that 8 moves ahead, and it shifts or jumps out.

  However, if the hook portion 29 of the folded-back portion 33 is detached from the tongue portion 17, the joint material 8 may move forward and may be displaced or jumped out. Even in such a case, in the present invention, the joint material 8 is prevented from moving forward and being displaced from or protruding from the counter 3.

  That is, as described above, the lower end 20 of the tongue portion 17 is configured to be positioned below the lower end 24 of the main body portion 16 of the side wall 13. Therefore, even if the hook portion 29 is detached from the tongue portion 17 and the joint material 8 moves forward, the front end portion 35 in which the insertion portion 28 is notched in the joint material 8 (FIG. 5A, FIG. b)) is regulated by contacting the tongue 17 (more specifically, the front edge 23 of the notch 18), so that the joint material 8 moves forward and deviates from or protrudes from the counter 3. Is suppressed.

  As described above, in the conventional joint material 41 as shown in FIG. 6, as shown in the present embodiment, when the front surface 12 of the counter 3 is inclined downward toward the rear, the shape of the front surface 12 of the counter 3 is formed. Along the side wall 13 of the counter 3.

  However, in this embodiment, the notch 18 is formed substantially parallel to the front surface 12 of the counter 3 (the front end 19 of the tongue portion 17), so that the front end 19 of the tongue portion 17 of the counter 3 is rearward. Even when the counter 3 is inclined at an acute angle (the angle formed between the top plate portion 11 and the front surface 12 of the counter 3 is an acute angle), the side wall of the counter 3 extends along the front end 19 of the tongue portion 17 of the counter 3. 13, and the entire area in the front-rear direction of the gap between the small apron 6 and the counter 3 can be closed.

  Therefore, the joint material 8 does not come out in front of the gap, performs sufficient water stop, and has a good appearance. Even if the front surface 12 of the counter is inclined forward at an obtuse angle (the angle formed by the top plate portion 11 of the counter 3 and the front surface 12 is an obtuse angle), the front surface 12 (tongue 17 of the counter 3). Can be mounted in the gap along the shape of the front end 19).

  In this embodiment, the joint material 8 is mounted on the side wall 13 of the counter 3, but is not engaged with the small apron 6. Therefore, after the large apron 5 is removed by maintenance or the like, the small apron 6 is moved forward. When it is slid and removed, the support of the small apron 6 that forms a gap with the counter 3 is lost, and the joint material 8 is released without being damaged. Therefore, the structure is cut and removed like conventional caulking. Compared to the above, the work of removing the joint material 8 from the gap is facilitated.

  Further, if the small apron 6 is returned to the original state after maintenance, a gap is formed again between the small apron 6 and the counter 3. Therefore, if the joint material 8 is newly attached to the gap, the caulking is again separated. The joint material 8 can be reused.

  In the above embodiment, the joint material 8 is attached to the side wall 13 which is one side of the counter 3 and the gap between the small apron 6 and the counter 3 is stopped. However, the joint material 8 of the present invention is It may be mounted not only on one side of the counter 3 but also around the counter 3.

  Moreover, you may mount | wear with the hook parts 29 in the bathtub side, such as the small apron 6, instead of the side wall 13 of the counter 3. Furthermore, it is good also as a structure which provides the hook part 29 in a bathtub, mounts | wears the joint material 8 around the bathtub, and closes the clearance gap between the wall surface adjacent to a bathtub, and another member.

  As mentioned above, although the form for implementing the joint material which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technical statement described in the claim It goes without saying that there are various embodiments within the scope of the matter.

  Since the joint material according to the present invention is configured as described above, it can be applied not only to the gap between the bathtub apron or the wall surface of the bathroom and the counter, but also to the water stoppage of the gap between the bathtub and the wall and other surrounding members. It is also applicable. Furthermore, the present invention can be applied to gaps between various other members as long as it is intended to stop water in the gap between two adjacent members regardless of a bathtub or the like.
