Description

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

  For example, there is a bathroom washroom floor having a first cushion layer of a foamed molded product made of a thermoplastic resin and a second cushion layer of a foamed resin molded product that is more flexible than the first cushion layer (patent) Reference 1). The second cushion layer is provided so as to be in close contact with the upper surface of the first cushion layer, and softens the surface of the washing floor. The first cushion layer is harder than the second cushion layer, and has a drainage gradient inclined toward a drain outlet provided on the upper surface of the washing place, a wall mounting portion on which a wall material is placed, and the like. It creates the shape of the floor and is manufactured by molding a foamed resin. For this reason, a plurality of different molds are required depending on the size of the bathroom, which is a factor that increases costs.

  Moreover, there is a waterproof floor pan for a bathroom provided with a wall-mounted portion made of a low-foam plastic material and a foamed plastic plate placed on the bottom plate so as to be spread in the wall-mounted portion (Patent Document 2). According to the waterproof floor pan described in Patent Document 2, since the foamed plastic plate is separate from the wall-mounted portion, it is not necessary to form the wall-mounted portion on the foamed plastic plate. However, in order to form a drainage gradient on the foamed plastic plate, it is necessary to change the thickness of the foamed plastic plate depending on the location. Therefore, a mold is required for manufacturing the foamed plastic plate.

In the bathroom floor of a bathroom, it is desired to reduce the cost of floor base materials such as the first cushion layer described in Patent Document 1 and the foamed plastic plate described in Patent Document 2.
As a solution to such a demand, the applicant of the present invention has made the floor base material a flat plate made of foamed resin according to Japanese Patent Application No. 2014-70698, and is directed on the floor base material from the end of the washing area to the drain outlet. We propose a washroom floor in which a cushioning material that gradually decreases in thickness is provided, and a drainage slope that slopes down toward the drainage outlet is formed on the surface of the washinghouse by changing the thickness of the cushioning material. However, in this washing floor, the cushion layer that gives softness to the surface of the washing place has a different thickness depending on the place, so that the treading feeling changes depending on the place.

JP 2013-253453 A Japanese Patent Application Laid-Open No. 11-343650

  The present invention has been made on the basis of recognition of such problems, and it is possible to provide a drainage gradient while using a flat plate made of foamed resin as a floor base material in order to reduce the cost of the floor base material. The purpose is to provide a bathroom floor where you can get the same level of comfort regardless of where you step.

  A first aspect of the present invention is a bathroom washroom floor provided on the surface of a washroom and having a drainage gradient inclined toward the drainage port, and is a foam formed on a support and formed as a flat plate with the upper surface parallel to the lower surface A resin base material and a cushioning property which is provided on the base material and which is higher than the cushioning property of the base material, and has a shape in which the thickness gradually decreases from the end of the washing area toward the drainage port. A cushion layer; and a surface layer provided on the cushion layer. The cushion layer has a compression amount of the first portion when a predetermined load is applied to a thickness of the first portion. It is a bathroom washroom floor characterized by having a compression amount adjusting means that is equivalent to the compression amount of the second portion having a different thickness.

  According to the washroom floor of this bathroom, the cushion layer whose thickness varies depending on the place is provided on the base material of the foamed resin molded product. Therefore, even when a foamed resin molded article having a certain thickness is used as the base material, a drainage gradient can be imparted to the surface of the washing place. Thereby, cost reduction can be aimed at.

  The amount of compression of the cushion layer for the same load varies depending on the thickness of the cushion layer. Specifically, when the same load is applied to the cushion layer, the compression amount of the relatively thick cushion layer is larger than the compression amount of the relatively thin cushion layer. Therefore, in the cushion layers having different thicknesses, the treading feeling of the washing place may differ depending on the place.

  On the other hand, according to the washroom floor of the bathroom, the compression amount adjusting means differs in the compression amount of the first part from the thickness of the first part when a predetermined load is applied to the cushion layer. The compression amount of the second part of the thickness is made equal. Thereby, for example, a user can feel the same stepping comfort even if the standing position is changed.

In addition, at the edge of the washing place where the cushion layer is thick, if the cushion layer is compressed in a large amount, the adhesive may peel off or the seal may be broken.
On the other hand, according to the washroom floor of this bathroom, since the amount of compression of the cushion layer at the end of the washroom where the thickness of the cushion layer is thick can be suppressed, it is possible to prevent the peeling of the adhesive and the destruction of the seal from occurring. can do.

  According to a second aspect of the present invention, in the first aspect of the invention, the compression amount adjusting means is a bathroom floor in which the foaming ratio of the cushion layer is lowered from the drain port toward the end.

  According to this washing place floor, the foaming ratio is increased in the relatively thin cushion layer portion, and the foaming ratio is decreased in the relatively thick cushion layer portion. Therefore, the relatively thin cushion layer is softer than the relatively thick cushion layer. On the other hand, a relatively thick cushion layer is harder than a relatively thin cushion layer. Thereby, the compression amount of the cushion layer with respect to the same load can be made substantially equal irrespective of the thickness of the cushion layer.

  In a third aspect based on the second aspect, the cushion layer has a plurality of cushion portions having different foaming ratios, and the plurality of cushion portions are expanded from the drain port toward the end portion. This is a bathroom washroom floor, which is arranged to gradually become lower.

  According to the washroom floor of this bathroom, the foaming ratio can be varied according to the thickness of the cushion layer by arranging the cushion portions having different foaming ratios. Thereby, a cushion layer can be more simply manufactured, without making the foaming magnification of a single cushion layer differ according to a place.

  In a fourth aspect based on the first aspect, the compression amount adjusting means has a slit extending in a thickness direction of the cushion layer, and the density of the slit in the first portion is the first density. It is a washroom floor of a bathroom characterized by being higher than the density of the slits in the second part that is thicker than the thickness of the bathroom.

  According to this bathroom washroom floor, the cushion layer in the portion where the slit density is relatively high is more easily compressed and deformed than the cushion layer in the portion where the slit density is relatively low. On the other hand, a portion of the cushion layer having a relatively low slit density is less likely to be compressed and deformed than a portion of the cushion layer having a relatively high slit density. Thereby, the compression amount of the cushion layer with respect to the same load can be made substantially equal irrespective of the thickness of the cushion layer.

  According to the aspect of the present invention, it is possible to provide a drainage gradient while using a flat plate made of foamed resin as a floor base material in order to reduce the cost of the floor base material. A bathroom wash floor can be provided.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic perspective view illustrating a bathroom unit including a bathroom wash floor according to an embodiment of the present invention.

  As shown in FIG. 1, the bathroom wash floor 1 is arranged next to the bathtub 2. A bath apron 9 is provided between the bathtub 2 and the washing floor 1 as a partition wall that separates the washing area from the bathtub installation section.

  In the washing floor 1 according to the present embodiment, a drain pipe 5 is laid under the washing floor 1, that is, in a space between the washing floor 1 and the bathroom installation surface. The drain pipe 5 connects the drain port 15 provided on the washing floor 1 and the drain pipe outside the bathroom.

  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 area 1a. It has a three-dimensional shape that prevents hot water from leaking out. The peripheral part of the washing place 1a shown in FIG. 1 is 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 place 1a ("surface" used in the following description refers to the surface inside the bathroom unless otherwise specified) so that hot water adhering to the surface of the washing place 1a flows to the drain 15 Therefore, drainage gradient surfaces 101, 102, 103, 104, and 105 that are inclined surfaces having a predetermined gradient toward the drainage port 15 are provided. This gradient is a downward gradient directed away from each side of the outer peripheral edge of the washing place 1a. Further, the boundary 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 101, 102, 103, 104 and 105. The gradient of the boundary line is a downward gradient directed away from each side of the outer peripheral edge of the washing place 1a.

  In the present embodiment, the drainage gradient surfaces 101 and 105 provided on the bathtub 2 side of the washing place 1a are disposed across both sides of the drainage port 15 therebetween. A boundary line L between the surface of the water blocking wall 1b (W) on the bathtub 2 side of the washing place 1a and the surface of the washing place 1a exists on the same straight line. The drainage gradient surfaces 101 and 105 have an inclination that becomes a downward gradient in a direction away from the boundary line L.

FIG. 2 is a schematic cross-sectional view taken along a cutting plane AA shown in FIG.
FIG. 3 is a schematic exploded view showing the structure of the washing place floor according to the present embodiment.
FIG. 4 is a schematic perspective view showing the washing floor according to the present embodiment.
FIG. 5 is a schematic perspective view showing the cushion layer of the present embodiment.

  As shown in FIGS. 2 and 3, the washing floor 1 according to this embodiment includes a support 11, a floor base material (also simply referred to as “base material”) 12, a cushion layer 13, and a surface layer 14. . 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 12 excluding the bathtub 2 side. Further, a standing wall portion 8 is attached to the floor base 12 on the bathtub 2 side.

  The support body 11 includes a frame 111 having length-adjustable support legs 112 and a high-strength support surface material 113 placed on the frame 111 so that the washing floor 1 can be installed at the floor height of the installation place. The height of the surface (the surface of the washing place 1a) can be adjusted. The support surface material 113 is provided with a work opening 113h and covered with a lid 114. The upper surface of the support surface material 113 covered with the lid 114 serves as a floor support surface that supports the floor base material 12.

  The floor base 12 is provided on the support 11. The cushion layer 13 is provided on the floor base material 12 and has a cushioning property higher than the cushioning property (elasticity) of the floor base material 12. The surface layer 14 is provided on the cushion layer 13 and has a hardness higher than that of the cushion layer 13. 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.

  The floor base 12 is formed as a flat plate with foamed resin. The upper surface of the floor substrate 12 is parallel to the lower surface of the floor substrate 12. The floor base 12 is not provided with a gradient. Therefore, the floor base material 12 does not need to have a complicated mold shape and can be manufactured at low cost.

  For example, the floor base material 12 can be formed by cutting a flat plate of foamed resin according to the size of the washing place 1a. That is, the floor base material 12 can be formed by cutting a foamed resin flat plate that has been formed into a long band shape into a required size. Thereby, the required number of metal mold | dies can be reduced significantly and the manufacturing cost of the floor base material 12 can be lowered | hung.

  Examples of the foamed resin 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 resins, it is possible to provide a floor structure with excellent strength that can withstand severe use.

  The cushion layer 13 is provided between the floor base material 12 and the surface layer 14. The cushion layer 13 includes a material having elasticity, such as polyurethane, and can give the washing floor 1 a moderate softness.

  The cushion layer 13 is formed with inclined surfaces 131a, 132a, 133a, 134a, and 135a serving as reference surfaces for forming the drainage gradient surfaces 101, 102, 103, 104, and 105 of the washing place 1a described above. Therefore, the cushion layer 13 has a shape in which the thickness is gradually reduced from the end of the washing place 1a toward the drain port 15 of the washing place 1a. In addition, the form of the drainage slope and the form of the slope are not limited to the examples shown in FIGS. 1 and 4.

  The inclined surfaces 131a to 135a are similar to the drainage gradient surfaces 101 to 105.

  The surface layer 14 includes a portion 14a that covers the floor base material 12 and the cushion layer 13 and forms the surface of the washing place 1a, and a portion 14b that covers the standing wall portion 8 and forms the surface of the water blocking wall 1b.

  The surface layer 14 is deformed so as to follow the inclined surfaces 131a to 135a of the cushion layer 13, and is adhered to the peripheral edge portion of the floor base material 12 so as to cover the surface of the floor base material 12.

  Arrow S1 shown in FIG. 4 represents the direction of each downward slope of the drainage gradient surfaces 101-105. That is, the direction in which the arrow S1 points indicates the downward direction. Thus, the drainage gradient surfaces 101 to 105 are inclined planes that descend from the sides of the outer peripheral edge of the washing floor 1 in the direction perpendicular to the sides.

  According to the washing floor 1 of the present embodiment, the floor base material 12 is formed as a flat plate made of foamed resin having a uniform thickness. Further, the thickness of the cushion layer 13 provided on the floor base material 12 is gradually reduced so as to become gradually thinner toward the drain port 15. As a result, a flat plate is used as the floor base material 12 and the thickness of the cushion layer 13 is changed to give a drainage gradient that slopes downward toward the drainage port 15 on the surface of the washing place 1a. Since the flat plate of the foamed resin does not require a complicated shape in the mold, it can be manufactured at a relatively low cost. Therefore, it is possible to manufacture the washroom floor 1 imparting a drainage gradient at a low cost using a flat plate made of foamed resin.

  Here, the compression amount of the cushion layer 13 with respect to the same load changes according to the thickness of the cushion layer 13. Specifically, when the same load is applied to the cushion layer 13, the compression amount of the relatively thick cushion layer 13 is larger than the compression amount of the relatively thin cushion layer 13. Therefore, when the thickness of the cushion layer 13 is different, the stepping comfort of the washing place 1a may be different depending on the place.

On the other hand, the cushion layer 13 of this embodiment has a compression amount adjusting means. The compression amount adjusting means makes the compression amount of the relatively thick cushion layer 13 equal to the compression amount of the relatively thin cushion layer 13. In other words, when the predetermined load is applied to the cushion layer 13, the compression amount adjusting means changes the compression amount of the first portion of the cushion layer 13 to a cushion having a thickness different from the thickness of the first portion. The amount of compression of the second portion of the layer 13 is made equal.
According to this, for example, the user can feel the same stepping comfort even if the standing position is changed.

Further, if the cushion layer 13 has a large amount of compression at the end portion of the washing area 1a where the cushion layer 13 is relatively thick, adhesion peeling or seal breakage may occur.
On the other hand, according to the washing place floor 1 according to the present embodiment, the amount of compression of the cushion layer 13 at the end of the washing place 1a where the thickness of the cushion layer 13 is relatively thick can be suppressed. And the occurrence of seal breakage can be suppressed.

A specific example of the compression amount adjusting means will be further described with reference to the drawings.
FIG. 6 is a schematic plan view showing a specific example of the compression amount adjusting means of the present embodiment.
FIG. 7 is a schematic cross-sectional view taken along a cutting plane BB shown in FIG.

  The cushion layer 13 of this specific example includes a first cushion material 131b that forms an inclined surface 131a, a second cushion material 132b that forms an inclined surface 132a, and a third cushion material 133b that forms an inclined surface 133a. The fourth cushion material 134b that forms the inclined surface 134a and the fifth cushion material 135b that forms the inclined surface 135a are divided.

  In this specific example, the cushion layer 13 includes a first cushion material 131b and a second cushion along a boundary line (valley line) between the inclined surfaces adjacent to each other among the plurality of inclined surfaces 131a to 135a. It is divided into a cushion material 132b, a third cushion material 133b, a fourth cushion material 134b, and a fifth cushion material 135b.

More specifically, the cushion layer 13 is divided into a first cushion material 131b and a second cushion material 132b at the boundary line between the inclined surface 131a and the inclined surface 132a. The boundary between the first cushion material 131b and the second cushion material 132b is along the boundary line between the inclined surface 131a and the inclined surface 132a.
The relationship between the second cushion material 132b to the fifth cushion material 135b is the same.
The division position of the cushion layer 13 is not limited to the example shown in FIG.

The first cushion material 131b includes a first cushion portion 131c and a second cushion portion 131d.
The second cushion material 132b includes a first cushion portion 132c, a second cushion portion 132d, and a third cushion portion 132e.
The third cushion material 133b includes a first cushion portion 133c, a second cushion portion 133d, and a third cushion portion 133e.
The fourth cushion material 134b includes a first cushion part 134c, a second cushion part 134d, and a third cushion part 134e.
The fifth cushion material 135b has a first cushion part 135c and a second cushion part 135d.

The third cushion material 133b will be described as an example with reference to FIG.
The second cushion portion 133d is provided between the first cushion portion 133c and the third cushion portion 133e. The first cushion part 133c is provided on the end side of the washing place 1a when viewed from the second cushion part 133d and the third cushion part 133e. The third cushion portion 133e is provided on the drain port 15 side when viewed from the first cushion portion 133c and the second cushion portion 133d.

  Therefore, the thickness of the first cushion part 133c is thicker than the thickness of the second cushion part 133d and the thickness of the third cushion part 133e. The thickness of the third cushion part 133e is thinner than the thickness of the first cushion part 133c and the thickness of the second cushion part 133d. The thickness of the second cushion part 133d is thinner than the thickness of the first cushion part 133c and thicker than the thickness of the third cushion part 133e.

  The expansion ratio of the material of the first cushion part 133c is lower than the expansion ratio of the material of the second cushion part 133d and the expansion ratio of the material of the third cushion part 133e. The expansion ratio of the material of the third cushion part 133e is higher than the expansion ratio of the material of the first cushion part 133c and the expansion ratio of the material of the second cushion part 133d. The expansion ratio of the material of the second cushion part 133d is higher than the expansion ratio of the material of the first cushion part 133c, and is lower than the expansion ratio of the material of the third cushion part 133e.

  That is, in this specific example, the first cushion portion 133c, the second cushion portion 133d, and the third cushion portion 133e are configured such that the foaming ratio gradually decreases from the drain port 15 toward the end of the washing place 1a. Is arranged.

  Thus, in this specific example, the compression amount adjusting means is configured such that the foaming ratio of the cushion layer 13 is lowered from the drain port 15 toward the end of the washing place 1a. More specifically, the compression amount adjusting means includes the first cushion portion 133c, the second cushion portion 133d, and the third cushion so that the foaming ratio gradually decreases from the drain port 15 toward the end of the washing place 1a. The cushion part 133e is arranged.

According to this example, the relatively thin cushion layer 13 is softer than the relatively thick cushion layer 13. On the other hand, the relatively thick cushion layer 13 is harder than the relatively thin cushion layer 13. Thereby, the compression amount of the cushion layer 13 with respect to the same load becomes substantially equal regardless of the thickness of the cushion layer 13.
Further, by arranging cushion portions having different foaming ratios (in this specific example, the first cushion portion 133c, the second cushion portion 133d, and the third cushion portion 133e), the cushion layers 13 are arranged according to the thickness. The expansion ratio can be varied. Thereby, the cushion layer 13 can be more easily manufactured without changing the foaming ratio of the single cushion layer 13 depending on the location.

  In this specific example, the third cushion material 133b has been described as an example. The structure of the first cushion material 131b, the second cushion material 132b, the fourth cushion material 134b, and the fifth cushion material 135b is the same as the structure of the third cushion material 133b. Further, in each cushion material, the number of divisions and the division positions are not limited to the examples shown in FIGS. 6 and 7.

FIG. 8 is a schematic cross-sectional view showing another specific example of the compression amount adjusting means of the present embodiment.
FIG. 8 is a schematic cross-sectional view taken along the cutting plane CC shown in FIG.
In this specific example, the cushion layer 13 does not have to be divided into a plurality of cushion materials as shown in FIG. Further, the cushion material is not divided into a plurality of cushion portions. As shown in FIG. 8, the cushion material is formed of one member.

  The cushion layer 13 has a plurality of slits (compression amount adjusting means) 138 provided on the lower surface (the surface placed on the floor base material 12). The slit 138 extends in the thickness direction (direction toward the upper surface) from the lower surface of the cushion layer 13. The depth of each slit 138 is substantially the same. The width of each slit 138 is substantially the same.

  As shown in FIG. 8, the density of the plurality of slits 138 provided in the relatively thin cushion layer 13 is higher than the density of the plurality of slits 138 provided in the relatively thick cushion layer 13.

  According to this specific example, the cushion layer 13 at a portion where the density of the plurality of slits 138 is relatively high is more easily compressed and deformed than the cushion layer 13 at a portion where the density of the plurality of slits 138 is relatively low. On the other hand, the cushion layer 13 in a portion where the density of the plurality of slits 138 is relatively low is less likely to be compressed and deformed than the cushion layer 13 in a portion where the density of the plurality of slits 138 is relatively high. Thereby, the compression amount of the cushion layer 13 with respect to the same load becomes substantially equal regardless of the thickness of the cushion layer 13.

  Note that the number of slits 138 and the positions of the slits 138 illustrated in FIG. 8 are examples, and are not limited thereto.

FIG. 9 is a schematic cross-sectional view showing still another specific example of the compression amount adjusting means of the present embodiment. FIG. 9 is a schematic cross-sectional view taken along the cutting plane CC shown in FIG.
In this specific example, the cushion layer 13 does not have to be divided into a plurality of cushion materials as shown in FIG. Further, the cushion material is not divided into a plurality of cushion portions. As shown in FIG. 9, the cushion material is formed of one member.

  The cushion layer 13 has a plurality of slits (compression amount adjusting means) 138 provided on the lower surface (the surface placed on the floor base material 12). The slit 138 extends in the thickness direction from the lower surface of the cushion layer 13. In this specific example, the depth of each slit 138 is different from the depth of the other slits 138.

  As shown in FIG. 9, the depth of the slit 138 provided in the relatively thin cushion layer 13 is deeper than the depth of the slit 138 provided in the relatively thick cushion layer 13.

  According to this example, the cushion layer 13 where the depth of the slit 138 is relatively deep is more easily compressed and deformed than the cushion layer 13 where the depth of the slit 138 is relatively shallow. On the other hand, the cushion layer 13 where the depth of the slit 138 is relatively shallow is less likely to be compressed and deformed than the cushion layer 13 where the depth of the slit 138 is relatively deep. Thereby, the compression amount of the cushion layer 13 with respect to the same load becomes substantially equal regardless of the thickness of the cushion layer 13.

  Note that the number of slits 138 and the positions of the slits 138 shown in FIG. 9 are examples, and are not limited thereto.

  Further, by changing the width of the slit 138, the compression amount of the cushion layer 13 with respect to the same load may be substantially equal regardless of the thickness of the cushion layer 13. For example, the width of the slit 138 provided in the relatively thin cushion layer 13 may be wider than the width of the slit 138 provided in the relatively thick cushion layer 13. In this case, the cushion layer 13 where the slit 138 is relatively wide is more easily compressed and deformed than the cushion layer 13 where the slit 138 is relatively narrow.
