Description

  The present invention relates to a bathroom wash floor structure, and more particularly to a structure for improving the state of attachment of a lid for a drain on a bathroom wash floor.

On the bathroom wash floor, a drain outlet is provided for draining used hot water that has flowed down onto the bathroom floor to the outside of the bathroom. Generally, a concave portion is formed on the upper side of the drain port, and a drain port lid is fitted into the concave portion so that the drain port does not remain open. I have to.
In such a drain outlet lid mounting structure, it is desirable that the lid does not have large backlash. For example, if there is a large backlash in the horizontal direction on the lid, the lid may be displaced in the horizontal direction when the bather steps on the lid, and the bather may slide his / her foot.
Therefore, conventionally, as in the means described in Patent Documents 1 and 2, for example, a protrusion is provided on the peripheral wall portion of the lid, and this protrusion is brought into contact with the inner wall of the concave portion on the upper side of the drainage port. There is a means for suppressing rattling of the lid.

  However, in the conventional means, there is some gap between the protrusion and the inner wall of the concave portion. For this reason, it is difficult to eliminate the backlash of the lid sufficiently. Although it is possible to eliminate rattling if the gap is made to be substantially zero, it is difficult to increase the dimensional accuracy, and it is necessary to strictly control the dimensions. There is a disadvantage in that the property is deteriorated and the manufacturing cost is increased. Furthermore, when the gap is substantially zero, the frictional resistance between the projection and the inner wall of the concave portion when the lid is put in and out of the concave portion is increased, so that the detachability of the lid is poor. Become.

Japanese Patent No. 3881979 JP 2006-291564 A

  The present invention has been conceived under the circumstances described above, and appropriately prevents or prevents rattling of the lid while avoiding problems such as deteriorating the detachability of the drain port lid. The challenge is to provide a wash floor structure that can be suppressed.

  In order to solve the above problems, the present invention takes the following technical means.

  A washing ground floor structure provided by the present invention includes a washing ground floor provided with a concave portion having an upper surface opening shape on the upper side of a drain outlet, and a drain outlet lid that is fitted into the concave portion and installed. In the wash floor structure, a pair of downward inclined surfaces are formed on the side wall portion or the back surface portion of the lid so as to be spaced apart from each other in the horizontal direction and to be closer to each other as they move upward. A protrusion is provided on the inner side of the recess, and the protrusion is positioned at a distance in the horizontal direction and is inclined so as to approach each other as it moves upward. An inclined surface is formed, and when the lid is fitted into the concave portion, the pair of downward inclined surfaces is supported on the pair of upward inclined surfaces so that the lid is supported by the protrusions. Can be configured as possible It is characterized in Rukoto.

According to such a configuration, the following effects can be obtained.
First, in a state where a pair of downward inclined surfaces formed on the lid is placed on a pair of upward inclined surfaces formed on the concave portion side of the washing floor, the pair of downward inclined surfaces is The pair of upward inclined surfaces exhibit a wedge action or a positioning action similar to the wedge action, and the positional displacement of the lid in the horizontal direction in which the downward inclined face and the upward inclined face are separated is appropriately prevented. For this reason, rattling of the lid is prevented or suppressed, and when the bather steps on the lid, the lid is inadvertently displaced and slips the foot.
Second, in order to prevent rattling of the lid as described above, the pair of downwardly inclined surfaces and the upwardly inclined surface may be formed so as to be in contact with each other. A very high dimensional accuracy is not required for the length of the surface. Of course, it is not necessary to increase the fitting accuracy between the lid and the concave portion. Therefore, manufacturing is easy and manufacturing cost can be reduced.
Thirdly, when the lid is taken in and out of the concave portion, there is no occurrence of a large frictional resistance that makes it difficult to put in and out between the pair of downward inclined surfaces and the upward inclined surface. Therefore, the operation of attaching / detaching the lid to / from the concave portion (detachment operation) is easy, and the handleability is excellent.

  In the present invention, preferably, the side wall portion of the lid is provided with a notch recess having a lower opening having a width in the horizontal direction, and inner wall surfaces at both ends in the width direction of the notch recess are the pair of the pair. It is a downward inclined surface.

  According to such a configuration, since the pair of downward inclined surfaces are formed by providing the notch recesses in the side wall of the lid, the size, weight, number of parts, etc. of the lid increase or increase. This is preferable in avoiding the above.

  In the present invention, preferably, as the protrusions, a pair of protrusions that protrude from the inner standing wall of the concave part toward the inside of the concave part and that are spaced apart in the horizontal direction are provided. Each of the pair of upward inclined surfaces is provided on the pair of protrusions.

  According to such a configuration, the pair of upward inclined surfaces can be appropriately formed while reducing the size of the protrusion provided in the concave portion.

  In the present invention, preferably, when the lid is fitted into the concave portion in a state where the pair of downward inclined surfaces is set in a direction different from the direction on which the pair of upward inclined surfaces are placed on the pair of upward inclined surfaces, The lid and the protruding portion interfere with each other, so that substantially the entire lid cannot be fitted into the concave portion.

  According to such a configuration, when the lid is inserted into the concave portion, if the direction of the lid is not set to the correct direction, it is not possible to properly fit the entire lid into the concave portion, Thus, a bather or the like can appropriately detect that the direction of the lid is not correct. This makes it possible for bathers and the like to expect the lid to be set to the correct orientation, and the lid is in the wrong orientation (the orientation of the positional relationship where the pair of downward inclined surfaces do not rest on the upward inclined surface). The effect that it is not left in the part is obtained. In the above-described configuration, the protrusions formed with the pair of upward inclined surfaces are used as means for setting the direction of the lid to the correct direction, and the configuration is reasonable.

  Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  The wash floor structure C shown in FIG. 1 includes a wash place waterproofing pan P used as a component of a bathroom such as a unit bath, and a lid 2 for a drain outlet. The washing place waterproofing pan P is entirely made of resin and forms the washing place floor 1. Although the washing place waterproof pan P can be configured as a bathtub-integrated type, in this embodiment, it is a separate type from the bathtub. A bathtub is installed beside the washing place waterproof pan P (on the other side of the one side edge 90 in FIG. 1).

  In the washing floor 1 near the one side edge portion 90 of the washing place waterproof pan P, the concave portion 4 having a substantially rectangular shape in a plan view, and drainage having a substantially circular shape in a plan view, for example, is located in the lower back of the concave portion 4. A mouth 3 is provided. A drain pipe (not shown) is connected to the lower side of the drain port 3 via a drain trap. The concave portion 4 is a portion for fitting and installing the lid 2 for the drain port, and is formed by the bottom wall portion 40 and a plurality of inner standing wall portions 41 that stand from the bottom wall portion 40. As will be described later, of the plurality of inner standing wall portions 41, the first inner standing wall portion 41 (41a) is provided with a pair of protruding portions 42 formed with a pair of upward inclined surfaces 42a to be described later. Yes.

  A pair of inwardly convex portions 44 that bulge partially so as to approach each other are provided on the second inner upright wall portion 41b (on the side edge portion 90 side of the washing place waterproof pan P) of the concave portion 4. ing. As shown in FIG. 4, the inner width L <b> 1 of the pair of inward convex portions 44 is narrower than the inner width L <b> 2 of the other portion of the concave portion 4. This helps to prevent the lid 2 from being installed in an orientation different from the original orientation, as will be described later.

In FIG. 1, the lid 2 includes a flat lid body 20 having a substantially rectangular shape in plan view, and a plurality of side walls 21 projecting downward from the outer peripheral edge of the lid body 20. Of the plurality of side walls 21, a first side wall 21 (21a) has a pair of downward inclined surfaces 22 to be described later. 4 and 5, the second side wall portion 21 (21 b) has a depression that is used to insert a finger into the back side of the lid 2 when the lid 2 is taken out from the concave portion 4. A portion 23 and a pair of left and right convex portions 24 are provided. The outer width L3 of the pair of convex portions 24 is smaller than the inner width L1 of the pair of inward convex portions 44. This makes it possible to fit the entire lid 2 into the concave portion 4 so that the portions where the pair of convex portions 24 are formed are arranged inside the pair of inwardly convex portions 44 ( (See also FIG. 2).

  1 and 3, the first side wall portion 21a of the lid 2 is formed with a notch recess 25 having a lower opening shape having an appropriate width in the lateral width direction x (horizontal direction) of the lid 2. The inner wall surfaces at both ends in the width direction of the notch recess 25 are a pair of downward inclined surfaces 22. The pair of downward inclined surfaces 22 are inclined surfaces inclined at an appropriate angle α so as to approach each other as they proceed upward. The other side wall portion 21 of the lid 2 is also provided with a notch recess 26, but this notch recess 26 is not for forming the downward inclined surface 22, but the lid 2 can be reduced in weight, This is a portion that serves as a passage for guiding hot water flowing into the concave portion 4 to the drain port 3.

  On the other hand, the first inner standing wall 41a of the concave portion 4 is provided with a pair of protrusions 42, and a pair of upward inclined surfaces 42a is formed on the pair of protrusions 42. As clearly shown in FIG. 3, the pair of protrusions 42 are spaced apart from each other in the lateral width direction x (horizontal direction) and are formed, for example, in a substantially triangular shape when viewed from the front. The outer inclined surfaces of the pair of protrusions 42 are upward inclined surfaces 42a that are inclined so as to approach each other as they progress upward, and have the same inclination angle as the inclination angle α of the downward inclined surface 22 described above. As shown in FIG. 3A, the pair of downward inclined surfaces 22 and the upward inclined surface 42a are placed in a surface contact state with the pair of downward inclined surfaces 22 on the pair of upward inclined surfaces 42a. The first side wall 21 a side is configured to be supported by the protrusion 42. As shown in FIG. 2, the second side wall portion 21 b side of the lid 2 rests on the bottom wall portion 40 of the concave portion 4 and is supported by the bottom wall portion 40. Although not shown in the drawings, a means for increasing the effect of preventing the displacement of the lid 2 on the lower surface portion of each side wall portion 21 of the lid 2 or when the lid 2 is placed on the bottom wall portion 40. A rubber material or the like can be provided as a means for reducing the impact.

  Next, the operation of the washing place floor structure C will be described.

  First, in a state where the lid 2 is fitted and installed in the concave portion 4, a pair of downward inclined surfaces 22 of the lid 2 are provided inside the concave portion 4 as shown in FIGS. 2 and 3A. A configuration placed on the upward inclined surface 42a is constructed. According to such a configuration, not only the movement of the lid 2 in the lateral width direction x is restricted by the contact between the inclined surfaces, but also the upward inclined surface by the weight of the lid 2 acting on these portions. An action (wedge action or action similar to this) in which 42a and the downward inclined surface 22 are pressed against each other is obtained. For this reason, displacement of the lid 2 in the lateral width direction x is substantially completely prevented. If such a displacement prevention is achieved, the rattling of the entire lid 2 is suppressed. As a result, when the bather steps on the lid 2, the lid 2 is inadvertently displaced and slips on the foot. It is possible to suitably prevent such a situation.

  In order to prevent rattling of the lid 2 as described above, it is only necessary that the entire pair of the downward inclined surface 22 and the upward inclined surface 42a are configured to face each other. When forming the inclined surfaces 22 and 42a, a very high dimensional accuracy is not required for these dimensional lengths. Appropriate play (gap) can be provided between the lid 2 and the concave portion 4, and it is not necessary to increase the accuracy of their fitting dimensions. Accordingly, the lid 2 and the washing floor 1 can be easily manufactured, and the manufacturing costs thereof can be reduced.

When the lid 2 is fitted into the concave portion 4, the pair of downward inclined surfaces 22 are placed on the pair of upward inclined surfaces 42a as they are, and no special operation is required. The same applies when the lid 2 is removed from the concave portion 4. A large frictional resistance that makes it difficult to put the lid 2 into and out of the concave portion 4 does not occur between the inclined surfaces 22 and 42a. For this reason, the operation of putting the lid 2 in and out of the concave portion 4 (detaching operation) is easy, and the handleability is excellent.

  The pair of downward inclined surfaces 22 is formed by providing a notch recess 25 in the first side wall portion 21 a of the lid 2. For this reason, formation of the downward inclined surface 22 is easy. It is possible to prevent an increase in the size, weight, and number of parts of the lid 2. It is also possible to make the cut-out recess 25 function as a hot water passage for drainage to promote drainage of hot water flowing into the concave portion 4. Since the pair of protruding portions 42 forming the pair of upward inclined surfaces 42a are provided so as to protrude from the first inner standing wall portion 41a of the recessed portion 4, it is also easy to mold or the like. The size of each protrusion 42 can also be reduced.

  FIG. 6 shows an example in which the direction of the lid 2 is set to the wrong direction in the reverse direction. Since the width L4 on the first side edge portion 21a side of the lid 2 is larger than the inner width L1 of the pair of inwardly convex portions 44, in this example, as shown in FIG. The second side edge portion 21 b side of the lid 2 protrudes from the concave portion 4. Accordingly, a bather or the like can accurately detect that the direction of the lid 2 is wrong, and the lid 2 is in the correct direction (a direction in which the pair of downward inclined surfaces 22 and the upward inclined surface 42a face each other). Can be expected to set.

  7 to 13 show other embodiments of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are denoted by the same reference numerals as those in the above embodiment, and redundant description is omitted.

In the embodiment shown in FIG. 7, the concave portion 4 provided on the washing floor 1 is formed in a substantially rectangular shape in plan view similar to the lid 2, and the inward convex portion 44 in the above embodiment is provided. Not.
In this embodiment, when the lid 2 is set in the orientation shown in FIG. 7, the pair of downward inclined surfaces 22 of the lid 2 are placed on the pair of upward inclined surfaces 42 a of the concave portion 4, 2 can be fitted into the concave portion 4. On the other hand, as shown in FIG. 8, when the lid 2 is turned in the opposite direction, the side edge portion 21 b of the lid 2 interferes with the pair of protrusions 42. For this reason, the substantially whole lid 2 cannot be properly fitted into the recessed portion 4. As a result, a bather or the like can accurately detect that the lid 2 is in the reverse direction, and the orientation of the lid 2 is set to the correct orientation.
According to the present embodiment, setting the lid 2 in the wrong direction is also appropriately prevented. Since the protrusion 42 for forming the upward inclined surface 42a is used as a part for preventing the lid 2 from being attached in an incorrect direction, the configuration is reasonable.

In the embodiment shown in FIG. 9, each of the first and third inner standing wall portions 41a and 41c of the concave portion 4 is provided with a protruding portion 42 having a pair of upward inclined surfaces 42a. Corresponding to this, the first and third side edge portions 21a and 21c of the lid 2 are each provided with a notch recess 25 that forms a pair of downward inclined surfaces 22.
According to such a configuration, the lid 2 can be accurately positioned not only in the horizontal width direction x but also in the vertical width direction y orthogonal thereto. Therefore, rattling of the lid 2 can be prevented more thoroughly.
In addition, although illustration illustration is abbreviate | omitted, in FIG. 9, in order to aim at the positioning fixation only of the y direction of the lid | cover 2, it is in the 1st inner side standing wall part 41a of the recessed part 4, and the 1st side wall part 21a of the lid | cover 2. The upward inclined surface 42 a and the downward inclined surface 22 are not provided, and the upward inclined surface 42 a and the downward inclined surface are provided only on the third inner standing wall portion 41 c of the concave portion 4 and the third side wall portion 21 c of the lid 2. It can also be set as the structure which provided the surface 22. FIG. In the present invention, it is sufficient that at least one pair of the upward inclined surface 42a and the downward inclined surface 22 is provided.

In the embodiment shown in FIG. 10, the concave portion 4 is used to position and fix the lid 2 in the x direction.
One of the pair of protrusions 42 having the upward inclined surface 42a provided on the first is provided on the first inner standing wall 41a, and the other is provided on the second inner standing wall 41b. . Corresponding to this, the notch recess 25 is provided in the first and second side wall portions 21a and 21b, and the downward inclined surface 22 is formed correspondingly.
Even with such a configuration, the lid 2 can be properly positioned and fixed in the x direction. As understood from the present embodiment, the pair of protrusions 42 formed with the pair of upward inclined surfaces 42 a and the downward inclined surface 22 of the lid 2 are not necessarily one common inner standing wall 41 or side wall 21. It does not need to be formed.

In the embodiment shown in FIG. 11, one protruding portion 42 extending in the horizontal direction is provided on the inner standing wall portion 41 a of the concave portion 4, and a pair of upward inclined portions are provided at both longitudinal ends of the protruding portion 42. A surface 42a is formed.
As understood from the present embodiment, in the present invention, it is not always necessary to provide a plurality of protrusions as means for forming the pair of upward inclined surfaces 42a.

In the embodiment shown in FIG. 12, the convex portion 24 is formed on the first side wall portion 21 a of the lid 2. A downward inclined surface 22 is formed on the downward surface of the convex portion 24, and this is opposed to the upward inclined surface 42a.
As can be understood from the present embodiment, the upward inclined surface provided in the lid does not necessarily have to be formed by providing a notch recess in the side wall of the lid.

In the embodiment shown in FIG. 13, a protruding portion 42 is provided that protrudes upward from the bottom wall portion 40 of the concave portion 4, and an upward inclined surface 42 a is formed on the protruding portion 42. On the other hand, a downwardly inclined surface 22 is formed on the back surface of the lid 2 so as to face the upwardly inclined surface 42a. The downward inclined surface 22 is not provided on the side wall portion 21 of the lid 2.
Also in this embodiment, it is possible to obtain the same operation as that of the above-described embodiment. As can be understood from the present embodiment, the protruding portion referred to in the present invention can be configured to be provided on the bottom wall portion instead of the inner standing wall portion of the concave portion. Further, the downward inclined surface referred to in the present invention may be formed on the back surface portion other than the side wall portion of the lid, instead of the side wall portion of the lid.

  The present invention is not limited to the contents of the above-described embodiment. The specific configuration of each part of the washing floor structure according to the present invention can be varied in design in various ways within the intended scope of the present invention.

The specific shape of the drain outlet lid and the concave portion of the washing floor is not limited to a substantially rectangular shape in plan view, and may be another shape such as a circular shape or a trapezoidal shape. It is also possible to provide the lid with a hole for passing water therethrough. The material of the lid is not limited, and instead of making the entire lid made of resin, for example, a metal plate made of stainless steel and a resin supporting the metal plate may be combined.
The washing floor does not necessarily have to be constructed using a waterproof pan that is resin-molded as a whole. In addition, the washing floor in the present invention is a concept including not only a bathroom in which a bathtub is installed but also a floor of a shower room in which no bathtub is installed.
