Description

  Aspects of the present invention generally relate to bathroom washroom floors.

  For example, there is a sanitary equipment room floor including a floor divided into a plurality of members and a surface material attached to the upper surface of the floor (Patent Document 1). In the sanitary equipment room floor disclosed in Patent Document 1, each of a plurality of members constituting the floor is formed of a resin molded body. The surface material is made of a resin sheet and has a function of improving cushioning properties.

  However, generally, a dimensional tolerance is set for a member formed of a resin molded body. For this reason, when a floor is formed by arranging a plurality of members, a step may be generated at a boundary portion between members adjacent to each other depending on the finished dimensions of the members. If a surface material having a relatively high cushioning property is provided on the step, the user may feel the step when stepping on the surface material on the step. As a result, there is a problem that the treading feeling deteriorates.

  Compared with a fiber reinforced plastic (FRP) molded product, it is difficult to produce a foamed resin molded product with precise dimensions. Therefore, when the member which comprises a floor is a foamed resin molded product, there exists a possibility that treading feeling may deteriorate further.

In the space under the washing floor 1, that is, in the space between the washing floor 1 and the bathroom installation surface H, a drain pipe 5 is laid to connect the drain port 15 provided in the washing floor 1 and a drain pipe outside the bathroom. ing. Usually, the drain port 15 is covered with a lid (not shown).

  The washing floor 1 is formed in a shallow vessel shape (bread shape) with the peripheral edge raised upward by providing a water blocking wall 1b so as to surround each side of the peripheral edge of the washing floor 1a. It has a three-dimensional shape that prevents leakage of hot water. The peripheral edge of the washing floor 1a shown in FIG. 1 has a substantially quadrangular shape. However, the shape of the peripheral edge of the washing floor 1a is not limited to a substantially quadrilateral. In the description of the present embodiment, the water blocking wall 1b provided on the bathtub 2 side is referred to as the water blocking wall 1b (W) when distinguished from other water blocking walls 1b.

  On the surface of the washing floor 1a (the "surface" used in the following description refers to the surface inside the bathroom unless otherwise specified), the hot water adhering to the surface of the washing floor 1a is drained. In order to flow up to 15, drainage gradient surfaces 110, 111, 112, and 113, which are inclined surfaces having a predetermined gradient, are provided toward the drainage port 15. This gradient is a downward gradient directed in a direction away from each side of the outer peripheral edge of the washing floor 1a. Further, the boundary line (valley line) between the drainage gradient surfaces adjacent to each other has a predetermined gradient toward the drainage port 15, similarly to the drainage gradient surfaces 110, 111, 112, and 113. The gradient of the boundary line is a downward gradient in a direction away from each side of the outer peripheral edge of the washing floor 1a.

  As shown in FIG. 2, the washing place floor 1 according to the present embodiment includes a floor base material 11, a cushion material 101, and a surface material 12. The washing floor 1 is provided on the support 6. A wall mounting member 7 on which a wall material of a bathroom unit (not shown) can be mounted is provided around the floor base material 11 excluding the bathtub 2 side.

  The floor substrate 11 is provided on the support 6. The cushion material 101 is provided on the floor base material 11 and has a cushioning property higher than the cushioning property (elasticity) of the floor base material 11. The surface material 12 is provided on the cushion material 101 and has a hardness higher than the hardness of the cushion material 101. In the present specification, “hardness” is equivalent to “hardness”. For example, Vickers hardness test (JIS Z 2244), Brinell hardness test (JIS Z 2243), or Rockwell hardness (JIS Z 2245). ) Is a measurable value based on the above.

  Since the floor base 11 forms a shape that forms the basis of the outer surface shape of the washing floor 1, a shallow vessel shape (bread shape) in which a peripheral edge similar to the surface shape of the washing floor 1 is bent upward. Is formed. Specifically, the floor base material 11 includes a floor surface portion 11a provided with a concave portion 15a that forms the drain port 15, and a standing wall portion 11b that is a standing wall provided so as to surround the peripheral portion of the floor surface portion 11a.

The inclined surface of the floor portion 11a is divided into drainage inclined surfaces 110a, 111a, 112a and 113a. The standing wall 11b is provided with a standing wall that serves as a reference surface for forming the water blocking wall 1b. Therefore, the surface of the floor base material 11 has a three-dimensional shape as a whole. The form of the drain slope and the form of the drain slope are not limited to the examples shown in FIGS. 1 and 3.

  The drainage inclined surfaces 110a, 111a, 112a, and 113a are similar to the drainage gradient surfaces 110, 111, 112, and 113, respectively. Further, the surface of the standing wall portion 11b is similar to the surface of the water blocking wall 1b. Strictly speaking, this three-dimensional surface shape is obtained by adhering the surface material 12 to the surface via the cushion material 101, so that the surface material 12 is separated from the drainage gradient surface and the water stop wall surface that are the surface shape of the washing floor 1. The shape is “offset” by the thickness, but this is referred to as “similar surface” in the present invention for convenience.

  As a material of the floor base material 11, foamable plastic (foamed resin) can be used. In the present embodiment, the floor substrate 11 is partially formed of foamed plastic including at least the surface layer.

  Examples of the foamed plastic include foamed polypropylene, foamed polystyrene, foamed polyethylene, and foamed polyurethane. In this embodiment, foamed polypropylene is used as an example. Since foamed polypropylene has higher impact resistance than other foamed plastics, the use of this makes it possible to provide a floor structure with excellent strength that can withstand severe use.

  The surface material 12 covers the floor surface portion 11a of the floor base material 11 and forms the surface of the washing floor 1a, and the surface of the floor base material 11 that covers the standing wall portion 11b and forms the surface of the water blocking wall 1b. Have.

The surface material 12 is bonded using, for example, an adhesive, a double-sided tape, or both of them. In the present invention, a state in which the surface material 12 is fixed in contact with a base member without a gap is referred to as “bonding”. Therefore, other fixing methods such as welding are also applicable.

  The cushion material 101 is provided between the floor base material 11 and the surface material 12. The cushion material 101 includes a material having elasticity such as urethane, and can give the washing floor 1 a moderate softness.

  The surface of the first floor member 111 b forms a drainage inclined surface 111 a of the floor base material 11. The surface of the second floor member 112 b forms a drainage inclined surface 112 a of the floor base material 11. The surface of the third floor member 113b forms a drainage inclined surface 113a of the floor base material 11. The fourth floor member 114 b forms at least a part of the drainage inclined surface 110 a of the floor base material 11. The fifth floor member 115 b forms at least a part of the drainage inclined surface 110 a of the floor base material 11. As described above, the recessed portion 15 a forms the drain port 15.

  In the present embodiment, the floor base material 11 includes the first floor member 111b at the boundary line (valley line) between the drainage inclined surfaces adjacent to each other among the plurality of drainage inclined surfaces 110a, 111a, 112a, and 113a. And a second floor member 112b, a third floor member 113b, a fourth floor member 114b, a fifth floor member 115b, and a concave portion 15a.

  More specifically, the floor base material 11 is divided into a first floor member 111b and a third floor member 113b at a boundary line between the drainage inclined surface 111a and the drainage inclined surface 113a. The boundary line between the first floor member 111b and the third floor member 113b is along the boundary line between the drainage inclined surface 111a and the drainage inclined surface 113a.

  The floor base material 11 is divided into a second floor member 112b and a third floor member 113b at the boundary line between the drainage inclined surface 112a and the drainage inclined surface 113a. The boundary line between the second floor member 112b and the third floor member 113b is along the boundary line between the drainage inclined surface 112a and the drainage inclined surface 113a.

  The floor base material 11 is divided into a first floor member 111b and a fourth floor member 114b at the boundary line between the drainage inclined surface 111a and the drainage inclined surface 110a. The boundary line between the first floor member 111b and the fourth floor member 114b is along the boundary line between the drainage inclined surface 111a and the drainage inclined surface 110a.

  The floor base material 11 is divided into a second floor member 112b and a fifth floor member 115b at a boundary line between the drainage inclined surface 112a and the drainage inclined surface 110a. The boundary line between the second floor member 112b and the fifth floor member 115b is along the boundary line between the drainage inclined surface 112a and the drainage inclined surface 110a.

The floor base material 11 is divided into a fourth floor member 114b and a concave shape portion 15a at the end of the concave shape portion 15a in the drainage inclined surface 110a. The floor substrate 11 is divided into a fifth floor member 115b and a concave shaped portion 15a at the other end of the concave shaped portion 15a in the drainage inclined surface 110a.
The division position of the floor base material 11 is not limited to the example illustrated in FIG.

  Here, generally, a dimensional tolerance is set for a resin molded product. Therefore, there may be variations in the finished dimensions of the resin molded product. In consideration of molding errors, variations in material shrinkage, and the like, variations in the finished dimensions of foamed plastic molded products may be larger than variations in the finished dimensions of fiber reinforced plastic (FRP) molded products. Therefore, each member (the 1st floor member 111b, the 2nd floor member 112b, the 3rd floor member 113b, the 4th floor member 114b, the 5th floor member 115b, the concave shape part 15a which the floor base material 11 has. ) May cause a step at the boundary between adjacent members.

  On the other hand, as described above, in the washing floor 1 of the present embodiment, the cushion material 101 having a cushioning property higher than the cushioning property of the floor base material 11 is provided between the floor base material 11 and the surface material 12. ing. Therefore, for example, when the user steps on the surface material 12 on the step between adjacent members, the step may be felt. Thereby, the treading feeling of the washing floor may be deteriorated.

  On the other hand, the washing floor 1 according to the present embodiment is provided with a step reducing member that loosens a step generated at the boundary between adjacent members among the members of the floor base material 11. Yes. The cushion material 101 and the surface material 12 are provided on the step leveling member.

  According to the present embodiment, even if a step (height difference) occurs in the boundary portion between adjacent members among the members of the floor base material 11, the step reducing member relaxes the step. Acts as follows. Therefore, for example, even when the user steps on the step from the top of the cushion material 101, it is possible to suppress the feeling of the step. Thereby, even if the floor base material 11 made of foamed resin, which is relatively difficult to manufacture with precise accuracy, is divided into a plurality of members, it is possible to prevent the washing comfort of the washing floor 1 from being deteriorated. The comfort during use can be maintained.

  In addition, as described above, the floor base material 11 includes the first floor at the boundary line (valley line) between the drainage inclined surfaces adjacent to each other among the plurality of drainage inclined surfaces 110a, 111a, 112a, and 113a. It is divided into a member 111b, a second floor member 112b, a third floor member 113b, a fourth floor member 114b, a fifth floor member 115b, and a concave shaped portion 15a.

  According to this, the boundary line between the drainage inclined surfaces adjacent to each other among the plurality of drainage inclined surfaces 110 a, 111 a, 112 a and 113 a has a downward inclination toward the drainage port 15. The step 141 is located below the boundary line between the drainage inclined surfaces adjacent to each other. Therefore, the step 141 does not divide the drainage inclined surfaces 110a, 111a, 112a, and 113a or the drainage inclined surfaces 110, 111, 112, and 113. Thereby, it can suppress that a dent arises on the surface of the washing floor 1 by the level | step difference 141, and can suppress that water accumulates in the dent. Therefore, it can suppress that the drainage performance of the washing floor 1 is impaired.

FIG. 5 is a schematic enlarged view in which the region B shown in FIG. 2 is enlarged.
FIG. 6 is a schematic plan view illustrating a specific example of the step reducing member of the present embodiment.
FIG. 7 is a schematic cross-sectional view showing a washroom floor according to a comparative example.
FIG. 7 corresponds to a schematic enlarged view in which the region B shown in FIG. 2 is enlarged.

  As shown in FIGS. 5 and 7, each member of the floor base material 11 (first floor member 111b, second floor member 112b, third floor member 113b, fourth floor member 114b, fifth Depending on the finished dimensions of the floor member 115b and the concave portion 15a), a step 141 may occur at the boundary between adjacent members. This is as described above with reference to FIGS. Further, a cushion material 101 having a cushioning property higher than that of the floor base material 11 is provided between the floor base material 11 and the surface material 12.

  Therefore, in the washing floor according to the comparative example shown in FIG. 7, for example, when the user steps on the surface material 12 on the step 141, the step 141 may be felt. Thereby, the treading feeling of the washing floor may be deteriorated.

  On the other hand, as shown in FIG. 5, the washing floor 1 according to the present embodiment is provided with a step reducing member 80 that makes the step 141 gentle. As shown in FIG. 6, the step reducing member 80 includes a flat portion 81 and an insertion piece 83. The insertion piece 83 is connected to the planar portion 81 and extends in a direction intersecting with the planar portion 81. For example, the insertion piece 83 is connected to the planar portion 81 and extends in a direction substantially orthogonal to the planar portion 81. The flat surface portion 81 is provided with a gradient 85 that decreases in thickness toward the end portion. The level | step difference relaxation member 80 is formed with resin (for example, elastomer etc.) softer than the floor base material 11 made from a foamed resin.

  As shown in FIG. 5, the flat surface portion 81 of the step reducing member 80 is a surface of the floor member (the first floor member 111 b and the third floor member 113 b in FIG. 5) that are adjacent to each other via the step 141. In FIG. 5, it is mounted on the drain slope 111a and the drain slope 113a). The insertion piece 83 of the step reducing member 80 is inserted between the floor members (the first floor member 111b and the third floor member 113b in FIG. 5) that are adjacent to each other via the step 141.

  According to this, even if the step 141 is generated at the boundary portion between the members adjacent to each other, at least the flat portion 81 of the step reducing member 80 is a softer resin than the floor base material 11 made of foamed resin. Therefore, the end portion of the flat surface portion 81 conforms to the respective surfaces of the floor members adjacent to each other through the step 141. On the other hand, even if the flat portion 81 follows the step 141 in the vicinity of the step 141, the insertion piece 83 contacts the side surface of one of the adjacent floor members (the floor member 111b in FIG. 5). A gap is created between the portion 81 and the other floor member (floor member 113b in FIG. 5). For this reason, the portion near the step 141 of the flat surface portion 81 does not completely follow the step 141 and adapt. Therefore, the step reducing member 80 can absorb the step 141. Therefore, for example, even when the user steps on the step 141 from above the cushion material 101, it is possible to prevent the user from feeling the step 141. Thereby, even if the floor base material 11 made of foamed resin, which is relatively difficult to manufacture with precise accuracy, is divided into a plurality of members, it is possible to prevent the washing comfort of the washing floor 1 from being deteriorated. The comfort during use can be maintained.
