Description

  The present invention relates to a joint material for a bathtub.

  When installing a bathtub in the bathroom, it is normal to install the edge (periphery) of the bathtub along the bathroom wall, and in the joint (gap) created between the edge of the bathtub and the bathroom wall The water stop treatment is applied so that water does not enter the joints along the wall surface. This water stop treatment is performed by installing a joint material so as to fill the joint, and as this joint material, a wet joint material made of a fluid material such as silicon or a dry joint material made of an elastic body is used. However, in general, a water-stopping treatment has been performed using the wet joint material. However, this water-stopping treatment using a wet joint material requires effort and skill to completely fill the joint with a wet joint material without damaging the appearance, and further into the joint. After filling, it had to be dried, which had the problem of poor workability.

In order to solve such a problem, for example, in order to perform a water stop treatment on the joint between the edge of the bathtub and the bathroom wall surface, a dry joint material having a better appearance and workability than a wet joint material is used. The joint structure of the edge of a bathtub and the bathroom wall surface is proposed (patent document 1). The joint structure will be described with reference to FIG. 4. The covering piece 2 for covering the upper part of the gap between the edge 61 of the bathtub 6 and the bathroom wall surface 7, and the leg piece suspended from the covering piece 2. The dry joint material 1 having the portion 3 and the fin piece 4 projecting from the leg piece portion 3 is pressed from above onto the gap between the edge 61 of the bathtub 6 and the bathroom wall surface 7. And press-fitting the fin piece 4 to the edge 61 of the bathtub 6 so that the cover piece 2 is pressed against the upper surface of the bathtub 6 and the bathroom wall surface 7 to prevent water W from entering the gap. Has been given.

  However, in the joint structure exemplified in Patent Document 1 and FIG. 4, when the joint material 1 is press-fitted, when the excessive pressure is applied, the leg piece portion 3 of the joint material 1 goes too far into the joint material 1. There was a problem that the upper surface of the covering piece portion 2 had a reverse gradient (gradient descending toward the bathroom wall surface 7), and water W was collected on the joint material 1 (that is, the upper portion of the covering piece portion 2).

  The present invention has been made to solve the above-mentioned conventional problems, and prevents the upper part of the joint material from being reversely inclined and prevents water from accumulating on the upper part of the joint material. It is an object to provide a joint material.

  In order to solve the above-mentioned problem, the present invention is a joint material press-fitted into a gap between the edge of the bathtub and the bathroom wall surface, and a covering piece made of an elastic body covering the gap above, In a joint material having a leg piece hanging from the covering piece, and a fin piece made of an elastic body projecting on the bathtub side and pressed against the edge of the bathtub in the middle of the leg piece It is characterized in that a round-shaped projection having a cross-section made of a soft material that comes into contact with the edge corner portion of the bathtub is provided above the portion.

  According to the present invention, it is possible to prevent the upper portion of the joint material from having a reverse gradient and to prevent water from accumulating on the upper portion of the joint material.

  The invention of the present application has the above-described features. Hereinafter, embodiments of the invention of the present application will be described in detail and specifically with reference to the accompanying drawings.

  FIG. 1 is a side sectional view illustrating an embodiment of a joint material for a bathtub according to the present invention. FIG. 2 is a perspective view illustrating a joint material for a bathtub according to the present invention.

  As illustrated in FIG. 1 and FIG. 2, the joint material 1 for a bathtub according to the present invention is a dry joint material 1, and closes a gap (joint) between the edge 61 of the bathtub 6 and the bathroom wall surface 7. The water stop treatment can be effectively performed.

  A joint material 1 according to the present invention comprises a cover piece 2 made of an elastic material such as a rubber material or a silicon material covering the gap, and a hard material such as a resin material that is suspended from the cover piece 2. A leg piece 3 and a fin piece 4 made of an elastic body such as a rubber material or a silicon material that protrudes from the bathtub 6 and presses against the edge 61 of the bathtub 6 are provided in the middle of the leg piece 3. This is a joint material 1. Then, above the leg piece portion 3 of the joint material 1, a cross-sectional round-shaped projection 5 (or a substantially semicircular cross-sectional projection) made of a soft material that abuts in the vicinity of the corner portion of the edge 61 of the bathtub 6 is provided. is doing.

  The structure of the joint material 1 of the present invention will be further described. The joint material 1 of the present invention is a linear longitudinal member along the bathroom wall surface 7, and is a leg piece from the lower surface of the substantially horizontal plate-shaped covering piece portion 2. The part 3 is suspended in a substantially vertical direction, and the longitudinal section is formed in a substantially T shape. That is, the joint material 1 of the present invention can be formed over the entire length in the longitudinal direction along the bathtub wall surface 7 of the bathtub 6.

  Here, the cover piece 2 is a portion that covers and covers the gap (joint) between the edge 61 of the bathtub 6 and the bathroom wall surface 7 (upper opening), and is an elastic body such as a rubber material or a silicon material. Is formed. Moreover, the leg piece part 3 is a part press-fitted in the gap between the edge 61 of the bathtub 6 and the bathroom wall surface 7 and is formed of a hard material such as a resin material such as plastic. preferable.

  The leg piece portion 3 extends downward from the lower surface in the vicinity of the wall surface side end portion 22 of the covering piece portion 2, and the wall surface side end portion 22 of the covering piece portion 2 is closer to the bathroom wall surface 7 than the leg piece portion 3. The bathtub-side end portion 21 of the cover piece 2 protrudes toward the bathtub 6 side. Further, the base of the leg piece 3 that is suspended from the lower surface of the cover piece 2 protrudes toward the bathtub 6 and contacts the edge 61 of the bathtub 6 (specifically, the vicinity of the corner 61 above the edge 61). The contact part 11 which contacts is formed, and the contact part 11 is formed of a hard material integrally with the leg piece part 3. And in the middle of the leg piece part 3, the fin piece 4 over a longitudinal direction is protrudingly provided by the multiple bathtub 6 side at substantially equal intervals in the up-down direction. Further, a buffer protrusion 41 that protrudes toward the bathroom wall surface 7 is provided on the leg piece portion 3 where the fin piece 4 protrudes so as to buffer the bathroom wall surface 7.

  Then, on the side of the bathtub 6 above the leg piece 3, a cross-sectional round-shaped protrusion 5 (or a substantially semicircular cross-sectional protrusion) extending over the entire length in the longitudinal direction of the bathtub 6 is located above the uppermost fin piece 4. Projected at

  The fin pieces 4 and the buffer protrusions 41 are formed of an elastic body such as a rubber material or a silicon material, and are pressed against the edge 61 of the bathtub 6 and the bathroom wall 7 when the leg piece 3 is press-fitted into the gap. The leg piece 3 press-fitted into the gap is formed so as to have an inclination directed upward so as to make it difficult to escape. The shape of the fin piece 4 will be further described. The fin piece 4 is formed to have a larger projection amount than the buffer projection 41 and to become thinner as it goes to the projecting tip. The cross-sectional round-shaped protrusion 5 (or the substantially semi-circular cross-section protrusion) is preferably formed of a soft material, and the cross-sectional round-shaped protrusion 5 (or the cross-sectional approximately semi-circular protrusion) is formed in the bathtub 6. It is possible to prevent excessive press-fitting into the gap between the leg piece portion 3 and eventually the joint material 1 by abutting against the corner portion 61.

  Usually, the bathtub 6 installed in the bathroom is installed along the bathroom wall surface 7. In the bathtub 6 installed in this way, a gap is formed between the edge 61 of the bathtub 6 and the bathroom wall surface 7, but the edge 61 of the bathtub 6 and the bathroom wall surface 7 exist. By fitting and arranging the joint material 1 of the present invention having the above-described features in the gap, it is possible to perform a water stop treatment that closes the gap and prevents water from entering the gap. That is, the leg piece portion 3 suspended from the covering piece portion 2 made of an elastic body is press-fitted into the gap, and the covering piece portion 2 covers and covers the gap. Further, at this time, the abutting portion 11 abuts in the vicinity of the upper corner portion of the end edge 61 of the bathtub 6 and is a cross-sectional round shape made of a soft material protruding above the fin piece 4 of the leg piece portion 3. The protrusion 5 (or a substantially semicircular protrusion in cross section) abuts near the corner portion of the edge 61 of the bathtub 6 below the contact portion of the contact portion 11, so that the leg piece portion 3 of the joint material 1 is in the back. Preventing you from entering too much.

  Thus, when press-fitting the joint material 1 of the present invention, when excessive pressing is applied, conventionally, the joint material 1 is pressed too far into the back, and the upper part of the covering piece portion 2 of the joint material 1 has a reverse gradient. Although it becomes a (gradient descending toward the bathtub wall surface 7), this can be prevented by the cross-sectional round-shaped protrusion 5 (or the substantially semicircular cross-sectional protrusion), and the upper part of the joint material 1 (that is, the covering piece) It is possible to prevent the upper surface of the portion 2) from being reversely inclined and to prevent water from accumulating on the joint material 1.

  In FIG. 1 and FIG. 2, the joint material 1 exemplifies a linear joint material 1 a formed along the longitudinal direction of the bathtub 6.

  Drawing 3 is a figure which illustrated another shape of the joint material for bathtubs of this invention, (A) is a top view and (B) is a side view.

  Further, as illustrated in FIGS. 3A and 3B, the joint material 1 of the present invention may be a bending joint material 1b. Basically, it has the same structure as the linear joint material 1a illustrated in FIG. 1 and FIG. 2, and the edge 61 of the bathtub 6 in the corner portion having the corner shape and the bathroom wall surface 7 in the corner portion having the corner shape. The cover piece portion 2 and the leg piece portion 3 are bent so that they can be aligned with each other.

  In the covering piece portion 2 of the bending joint material 1b, the dimension between the bathtub side end portion 21 and the wall surface side end portion 22 (hereinafter referred to as the width dimension) is the covering piece portion of the linear joint material 1a. The overall length in the longitudinal direction is longer than the overall length in the longitudinal direction of the leg piece 3. That is, both end portions in the longitudinal direction of the covering piece portion 2 are located on the outer side in the longitudinal direction with respect to both end portions in the longitudinal direction of the leg piece portion 3. Further, a fold piece 23 extending outward from the upper surface of the cover piece portion 2 is formed in the wall surface side end portion 22 of the cover piece portion 2 of the bending joint material 1b in the longitudinal direction. And this crease piece 23 is formed so that the extension amount may become large in the corner part of the bending type joint material 1b where the cover piece part 2 and the leg piece part 3 bend.

  As mentioned above, the joint material 1 of this invention is good also as the linear joint material 1a which can be arrange | positioned in the clearance gap between the edge 61 of the linear bathtub 6, and the linear bathroom wall surface 7, or corner shape It is good also as the bending type joint material 1b which can be arrange | positioned in the clearance gap between the edge 61 of the bathtub 6 of the corner part, and the bathroom wall surface 7 of the corner part of a corner corner shape. Therefore, according to the shape of the gap (joint shape), the joint material 1 of the present invention can be appropriately arranged with the straight joint material 1 a and the bent joint material 1 b, and the edge of the bathtub 6 along the bathroom wall surface 7. The gap between the edge 61 of the bathtub 6 and the bathroom wall surface 7 can be closed over the entire length 61. And since the leg piece part 3 of the joint material 1 can be prevented from entering too far by the cross-sectional round-shaped protrusion 5 (or the substantially semicircular cross-sectional protrusion), the upper part of the cover piece part 2 of the joint material 1 Can be prevented from becoming a reverse gradient (that is, the wall surface side end portion 22 descends from the bathtub side end portion 21 of the cover piece 2 and descends toward the bathroom wall surface 7). It is possible to prevent water from accumulating on the upper portion of the. That is, the upper part of the joint material 1 forms a gradient that decreases toward the bathtub 6 side, and the water flows toward the bathtub 6 side.

  Of course, the joint material 1 of the present invention is not limited to the above examples. For example, the material of the cover piece 2 and the fin piece 4 is not particularly limited, and examples thereof include resin materials such as plastic materials, rubber materials, silicon materials, and the like. Further, the soft material having the round-shaped projection 5 (or a substantially semicircular cross-section) can be exemplified by various materials such as a rubber material and a silicon material, and is not particularly limited.

  In addition, the shape of the joint material 1 of the present invention can also be set in various forms.
