Description

  The present invention relates to a waterproof floor pan that constitutes a floor of a unit bath or the like, and more particularly to a waterproof floor pan having a bank portion that supports a bathtub apron that covers a bathtub side surface.

  The structure of the unit bus or the system bus is roughly divided into a half structure and a full pan structure. The former is also referred to as a bathtub with a washing area or a bathtub with an integrated washing area, in which a floor of a washing area and a bathtub are integrally formed on a frame, and a wall panel is erected on the rim of the bathtub. In the latter, a bathtub is placed on a waterproof pan laid on the entire floor via a gantry, and a wall panel is also provided on the outer edge of the waterproof pan.

  Of these, as shown in FIG. 8, the waterproof floor pan having a full pan structure is partitioned into a washing section 101 where a bather wash his hair and body, and a bathtub mounting section 102 on which a bathtub 108 is mounted, and the boundary between them In the portion, a bank portion 104 on which an apron 103 covering the side surface of the bathtub 108 visible from the washing section 101 side is placed is erected.

  In addition, a bathtub drainage port 106 is provided in the vicinity of the bank portion 104 of the bathtub mounting portion 102, and a washing ground drainage port 107 is provided in the vicinity of the bank portion 104 of the washing ground portion 101. The sewage is collected here and then drained to the outside.

The washing floor 101 of the waterproof floor pan 100 is provided with a drainage gradient S that guides the water used in the washing floor 101 to the drain trap 105 and collects water in the vicinity of the bank 104, which is the lower part of the washing floor 101. Therefore, the bank portion 104 is required to have a certain height to prevent the washing ground drainage from overflowing to the bathtub mounting portion 102 side. As shown in FIG. 8 (a), this is an integrated type in which the washing area 101 and the bathtub mounting portion 102 are integrally formed (see, for example, Patent Document 1), FIG. 8 (b). As shown in FIG. 4, the same thing can be said even if the separate type is formed separately (see, for example, Patent Document 2). The same applies to the case where the drain trap is at the center in the length direction of the bank 104 or at either end thereof.

  However, when the drainage slope S is taken as described above, for example, when the drain trap 105 is at the center in the length direction of the bank portion 104, the drain trap 105 can be provided even if the height of the end of the bank portion 104 falls within a certain level. In the vicinity, it grows up and looks bad. In addition, since the corner formed between the lower end of the bank 104 and the end of the washing section 101 on the bank 104 side is formed in a slope that descends toward the drain trap 105, this eliminates the need for the drain gradient S. There is also difficulty in emphasizing it. When the drain trap 105 is provided at the end of the bank 104, the slope becomes longer while the magnitude of the drain gradient S is the same, and this tendency becomes more remarkable.

  The present invention has been made in consideration of the above-mentioned circumstances, and while maintaining the conventional drainage gradient to ensure drainage performance, the apparent height of the bank portion and the inclination of the lower end are reduced to improve the design. An object of the present invention is to provide an improved waterproof floor pan.

In order to solve the above-described problem, the waterproof floor pan according to the present invention includes a washing place where a bather wash and wash the body, and a bathtub installed adjacent to the washing area , as described in claim 1. , a bathtub apron for obscuration of the side surface of the washing area side of the tub, and a bank portion which projects upwardly above the bathtub side edge of the washing area portion in order to support the bath tub apron, close to the該土hand portion In the waterproof floor pan having a drain trap that is disposed and drains the water generated in the washing section, the washing section is provided with a drain gradient that descends toward the drain trap,
Between the lower end position and the bank portion from the side surface the upper end of the upper Symbol bank portion lowered a predetermined height arc surface is formed, said arcuate surface, the waste water from a remote water portion from the Symbol drain trap The radius of curvature R is increased as it approaches the underwater portion near the trap .

  According to the waterproof floor pan of the present invention, it is possible to improve the design by reducing the apparent height of the bank and the inclination of the lower end while maintaining the drainage performance by maintaining the conventional drainage gradient. .

  The present invention provides an effect that the R between the floor surface / bank portion near the drainage trap that is most likely to become dirty is increased, and cleaning is facilitated.

  An embodiment of a waterproof floor pan according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view showing an outline of a waterproof floor pan 1 and a bathtub 5 placed on the waterproof floor pan 1 according to the present embodiment, FIG. 2 is a longitudinal sectional view thereof, and FIG. 3 is a waterproof floor. It is a top view of the washing place part 2 which comprises a part of bread.

  As shown in FIG. 1, the waterproof floor pan 1 shown in this embodiment includes a washing place 2 formed of a resin material such as FRP and a bathtub mounting portion formed of a heat insulating material such as foamed polypropylene or foamed polystyrene. 3 is a separate type united and integrated.

  As shown in FIG. 2, a bank portion 4 is erected at a connection portion between the washing place 2 and the bathtub mounting portion 3 of the waterproof floor pan 1. In addition, a washing ground drainage port 8 is provided at the lowest position of the washing place 2, and a bathtub drainage opening 9 is provided at the lowest position of the bathtub mounting portion 3, and these are drainage installed behind the waterproof floor pan 1. Connected to trap 7.

  On the bathtub mounting part 3, the bathtub 5 is mounted by being supported by a support leg. A bathtub apron 6 that covers the side surface of the bathtub 5 is installed between the rim end of the washing section 2 side of the bathtub 5 and the top end of the bank section 4.

  As shown in FIG. 3, the washing section 2 has a wall panel mounting section 2a on which wall panels constituting the wall surface of the unit bath are erected on the outermost edges of three sides except the bathtub mounting section 3 during the four-rounds. A connecting portion 2b with the bathtub mounting portion 3 is formed at the end facing the bathtub mounting portion 3. The connecting portion 2b constitutes the side surface of the bank portion 4 on the washing place portion 2 side.

  The outer edge of the washing area 2 is formed at the same level over the entire circumference, and a drainage gradient S descending from the outer edge of the washing area 2 toward the washing area drain 8 formed at the center in the length direction of the bank 4 is provided.

  In addition, the substantially entire surface of the central portion of the washing section 2 is formed as a main portion 2c whose surface is roughened so that the bather does not slip and fall, while the wall panel mounting portion 2a and A portion corresponding to the inner side of the connecting portion 2b is formed as a border portion 2d having a fixed width and a smooth surface.

  In addition, at the corner formed between the bank portion 4 side end of the washing section 2 and the bottom end of the bank portion 4, a curvature described later is shown as a hatched portion along the connection portion 2 b in FIG. 3. The radii R are formed on different circular arc surfaces Q.

  FIG. 4 in which the periphery of the bank part 4 in FIG. 2 is enlarged shows a connection structure between the connection part 2b of the washing place part 2 and the connection part 3a on the bathtub mounting part 3 side. The connecting section 2b on the washing section 2 side is erected from the floor surface over the entire length of the side facing the floor on the bathtub mounting section 3 side of the washing section 2 and is placed on the bathtub in the vicinity of its upper end. A flange 30a extending substantially horizontally in the floor direction on the part 3 side is provided. On the upper surface of the flange 30a, a waterproof packing 32 such as an elastomer is placed over the entire length.

  Similarly, the connection part 3a on the bathtub mounting part 3 side is bent up from the floor surface over the entire length of the side where the floor on the bathtub mounting part 3 side faces the floor on the washing place part 2 side, and its upper end. In the vicinity, at a position higher than the flange 30a of the connecting portion 2b of the washing place 2, a brim 40a extending substantially horizontally in the floor direction on the washing place 2 side is provided. A support material 41 in which a stainless steel plate or the like is bent in a substantially U-shape is fitted over the flange 40a over its entire length.

  A plurality of screw holes 30b are formed at predetermined intervals in the flange 30a, insertion holes 40b, 41a, 41b are formed in the flange 40a and the support member 41, and insertion holes 31a are formed in the water-stopping packing 31, respectively. A plurality of holes are formed at intervals. Then, the screw 32 is inserted into the screw hole 30b and the insertion holes 41a, 41b, 40b, and 31a, and the flange 30a of the washing side connection part 30 and the flange 40a of the bathtub side connection part 40 are tightly connected.

  The screw 32 is screwed only into the screw hole 30b of the flange 30a, and is loosely inserted without screwing into the insertion hole 40b of the flange 40a and the insertion holes 41a and 41b of the support member 41. Therefore, even if the flange 40a is formed of a flexible material, the insertion hole 40b is not damaged as the screw 32 advances. In addition, since the flange 40a is sandwiched between the upper and lower sides of the rigid support member 41, the floor 40 and the bathtub mounting unit 3 side are not pressed and deformed as the screw 32 is screwed. The floor is firmly connected.

  The bathtub apron 6 is supported via the joint material 45 on the connecting part 2b on the washing place part 2 side thus connected.

  Next, details of the connection between the end of the washing section 2 on the bank 4 side and the lower end of the bank 4 constituting the main part of the present invention will be described with reference to FIG. 4A is a longitudinal sectional view of the vicinity of the end of the bank portion 4 along the line AA in FIG. 1, and FIG. 4B is a sectional view along the line BB of FIG. 6 is a longitudinal sectional view of the vicinity of the center in the length direction of a portion 4. FIG.

  As shown in FIG. 4A, in the vicinity of the end of the bank portion 4, the corner formed at the intersection of the bank portion 4 side end of the washing place 2 and the lower end of the bank portion 4 is the bank portion. A radius of curvature centered on a point O1 on a line extending perpendicularly from the reference point P to the side surface of the connecting portion 2b, with a position P that is a certain height H lower than the upper end of the side surface 4 as a reference point (starting point) An arc surface Q1 of R1 is formed, and this arc surface Q1 is smoothly connected to the connecting portion 2b and the border portion 2d of the washing place 2.

  Similarly, in the vicinity of the center in the length direction of the bank portion 4, as shown in FIG. 4 (b), a corner formed between the end portion on the bank portion 4 side of the washing place portion 2 and the lower end of the bank portion 4 is formed. Is a curvature centered on a point O2 on a line extending perpendicularly from the reference point P to the side surface of the connecting portion 2b, with a position P lowered from the upper end of the side surface of the bank portion 4 by a certain height H as a reference point. An arc surface Q2 having a radius R2 is formed, and the arc surface Q2 is smoothly connected to the connecting portion 2b and the border portion 2d of the washing place 2.

  By the way, the vicinity of the edge of the bank portion 4 is above the drainage slope S and near the center in the length direction, so that the floor near the center of the bank portion 4 close to the drain trap 6 is closer to the floor of the washing section 2. The surface becomes lower, and as can be understood by comparing the two figures, the height of the bank portion 4 increases accordingly in the vicinity of the center.

  Thus, even if the height of the bank portion 4 increases from that shown in FIG. 4A to that shown in FIG. 4B, the height of the reference point P that is the starting point of the arcuate surfaces Q1 and Q2 is Since it does not change, by increasing the curvature radius R in accordance with the change in the height of the bank portion 4, the size of the arc surface Q is also changed, so that it can be smoothly connected to the washing place 2 and retained.

  As a result, the boundary becomes ambiguous compared to the connecting portion between the conventional washing place 2 and the bank portion 4 indicated by a broken line in the figure, and the rise of the bank portion 4 becomes inconspicuous and the design is improved. Nevertheless, since the drainage gradient itself of the washing place 2 is the same as the conventional one, the same level of drainage performance can be maintained.

  In addition, the corner portion between the wash floor / bank portion, particularly the water portion in the vicinity of the drain trap, is the most easily contaminated portion, but since the radius of curvature R of the corner portion increases, cleaning becomes easy. In addition, the side of the bank part forms a substantially vertical surface like the bath apron and is at a low position, so it is difficult to put effort into cleaning, but the area of this vertical surface is reduced, so the cleanability Is significantly improved.

  In the present embodiment, the centers O1 and O2 of the arc surfaces Q1 and Q2 have been described by taking as an example the case where the centers O1 and O2 are set on a line extending perpendicularly from the reference point P to the side surface of the connection portion 2b. The positions of the centers O1 and O2 of the surfaces Q1 and Q2 are not limited to this, and may be set on a line extended at an angle θ from the side surface of the connecting portion 2b of the washing place 2 as shown in FIG.

  Further, in the waterproof floor pan 1 according to the present embodiment, the arc surface Q is cut at the center of the bank portion 4 by the washing ground drain port 8. However, as shown in FIG. 6, the design can be made such that the washing ground drain port 8 is shifted to the washing section 2 side and the arc surface Q is continuous. According to this configuration, although the effective area of the washing place 2 is slightly reduced, the design around the bank 4 is improved.

  Further, as shown in FIG. 7, the main portion 2 a of the washing place 2 may be extended to the vicinity of the reference point P of the connecting portion 2 b, that is, the rough portion may be formed to the side surface of the bank portion 4. According to this, since the smooth surface portion on the surface of the bank portion 4 becomes small, an effect that the rising edge looks smaller visually can be obtained.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, and these embodiments are also included in the scope of the present invention.

  For example, in the present embodiment, the case where the drain trap is in the center of the bank portion length direction, that is, the case where the drain gradient is provided so as to be symmetrically lowered toward the center is described as an example. However, the present invention is not limited thereto, and it may be provided at one end of the bank portion, and the drainage gradient may be provided in a single-flow manner on the washing place portion.

  In the present embodiment, a separate waterproof floor pan in which the washing area and the bathtub mounting portion are separately formed has been described as an example. However, these are integrally formed integrally. But of course there is no problem.
