Summary of the Invention

Problems to be Solved by the Invention

[0004] In the configuration disclosed in Patent Document 1, illumination light is directly irradiated onto the user from around the roll paper. Also, in the configuration disclosed in Patent Document 2, the illumination light irradiated from the paper holder is directly irradiated onto the user. At this time, since the illumination light directly enters the user's eyes, it promotes the user's waking up in the middle of the night.

[0005] This disclosure has been made to solve the above problems, and its object is to provide a toilet room that can suppress the user's waking up in the middle of the night when using the toilet room at night.

Means for Solving the Problems

[0006] A restroom according to a first embodiment for solving the above problems comprises a toilet bowl, a side wall provided to the side of the toilet bowl, a covering plate having a covering portion extending from the side wall toward the room and an extension portion extending from the covering portion toward the direction away from the toilet bowl, a holder provided below the covering portion for holding a roll of paper, a light source provided below the extension portion, and a lateral restricting portion extending downward from the extension portion to restrict the light from the light source from being guided toward the side wall, wherein a first opening is formed between the side wall, the extension portion and the lateral restricting portion to open the space below the extension portion toward the covering portion, and the holder is positioned such that the roll of paper overlaps the first opening when viewed from the covering portion toward the first opening along the direction in which the extension portion extends.

[0007] According to the first embodiment, the toilet has a lateral restricting portion that extends downward from the extended portion, and the roll paper is positioned so that it overlaps the first opening when viewed from the covering portion. As a result, the light from the light source is blocked by the lateral restricting portion and the roll paper. This prevents the light from the light source from directly shining on the user of the toilet, thus preventing the user from waking up in the middle of the night due to direct light from the light source. In addition, since the roll paper is illuminated by the light from the light source, the visibility of the roll paper is improved.

[0008] A restroom according to the second embodiment is preferably provided with the following additional features in addition to those of a restroom according to the first embodiment. That is, the restroom according to the second embodiment further includes a downward restricting part which is provided below the light source with a gap formed between it and the light source and which restricts the downward guidance of light from the light source, and the upper surface of the downward restricting part is set to be above the lowest end position of the roll paper held by the holder.

[0009] According to the second embodiment, the downward restricting portion can restrict the light irradiated downward from the light source. Furthermore, by narrowing the area of ​​the first opening formed between the side wall, the covering plate, and the lateral restricting portion with the downward restricting portion, the light irradiated from the light source toward the toilet through the first opening can be more effectively restricted by the roll paper.

[0010] A restroom according to the third embodiment is preferably provided with the following additional features in addition to those of a restroom according to the first or second embodiment: In the restroom according to the third embodiment, at least one of the lateral restricting portion and the downward restricting portion is provided with an adjustment mechanism for adjusting the area of ​​the opening for allowing light from the light source to pass through.

[0011] According to the third embodiment, the brightness inside the dressing room can be adjusted by adjusting the area of ​​the opening using an adjustment mechanism as needed, thereby adjusting the amount of light irradiated from at least one of the sides and the bottom.

[0012] A restroom according to the fourth embodiment is preferably a restroom according to any of the first to third embodiments, further comprising the following features: In the restroom according to the fourth embodiment, a second opening is formed between the side wall, the extension, and the lateral restricting portion, which opens the space below the extension in a direction away from the toilet.

[0013] According to the fourth embodiment, by allowing the illumination of light directed in a direction that is unlikely to directly shine upon the toilet user, the restroom can be brightly illuminated while suppressing the user from waking up in the middle of the night.

[0014] A restroom according to the fifth embodiment is preferably a restroom according to any of the first to fourth embodiments, further comprising the following features: In other words, in a restroom according to the fifth embodiment, the extension is provided below a standard height predetermined as the eye level of the toilet user.

[0015] According to the fifth aspect, since the extension portion is interposed between the user's line of sight and the light source, it is possible to appropriately suppress the user's intermediate awakening.

Effect of the Invention

[0016] According to the present disclosure, it is possible to provide a dressing room that can suppress the user's intermediate awakening when using the dressing room at night.

Mode for Carrying Out the Invention

[0018] [Embodiment] The dressing room 10 according to the embodiment of the present disclosure will be described with reference to the drawings (FIGS. 1 to 7). In FIGS. 1 to 7, the front, rear, left, right, upper, and lower directions are shown. However, these directions are for convenience in explaining the dressing room 10 according to the present embodiment, and do not limit the structure and usage mode of the dressing room 10 according to the present disclosure. In the present embodiment, the front-rear direction is defined such that the entrance side of the dressing room 10 is the front direction and the back side of the dressing room 10 is the rear direction. Also, the left-right direction is defined such that the left side of the user when sitting on the toilet 12 is the left direction and the right side of the user is the right direction.

[0019] Figure 1 is a top view of the toilet room 10 seen from above. As shown in Figure 1, the toilet room 10 includes a toilet 12, a pair of side walls 14L and 14R provided on the side of the toilet 12, a rear wall 15 provided behind (the back side) of the toilet 12, a door 16 provided in front (the entrance side) of the toilet 12, and a paper holder 20 provided on the side wall 14L for holding the roll paper 18.

[0020] The toilet room 10 includes a space surrounded by the side walls 14L, 14R, the rear wall 15, and the door 16. The toilet 12 is arranged behind the toilet room 10.

[0021] [Structure of the paper holder] Figure 2 is a view of the paper holder 20 in Figure 1 seen from the direction of arrow A. Figure 3 is a view of the paper holder 20 in Figure 1 seen from the direction of arrow B (the front direction). Note that the roll paper 18 shown in Figures 2 and 3 is in the state before use, that is, the state with the maximum diameter.

[0022] The paper holder 20 includes a holder 22, a covering plate 32 having a covering portion 24 and an extending portion 26, a lighting 28, a side regulating portion 30, and a lower regulating portion 38. The holder 22 is provided below the covering portion 24 and holds the roll paper 18. The covering portion 24 extends from the side wall 14L into the room and covers the roll paper 18 held by the holder 22 from above. The extending portion 26 extends from the covering portion 24 in a direction away from the toilet 12. The lighting 28 is provided on the lower surface 26d of the extending portion 26 so as to irradiate light downward. The side regulating portion 30 extends downward from the extending portion 26 so as to regulate the light from the lighting 28 from being guided in a direction away from the side wall 14L. The lower regulating portion 38 is provided below the lighting 28 with a gap formed between the lower regulating portion 38 and the lighting 28 and regulates the light from the lighting 28 from being guided downward.

[0023] The holder 22 is a metal fitting provided for holding the roll paper 18. The holder 22 has a first member 22a that extends vertically along the side wall 14L, a second member 22b that extends inward from the upper end of the first member 22a, and a third member 22c that extends downward from the tip of the second member 22b.

[0024] The first member 22a extends vertically along the side wall 14L. The upper end of the first member 22a extends to a position where it abuts against the lower surface 32d of the covering plate 32. The first member 22a may be fixed to the side wall 14L by screws or the like. In this case, the holder 22 is provided on the side wall 14L.

[0025] The second member 22b extends perpendicularly from the upper end of the first member 22a to the side wall 14L. The second member 22b extends along the lower surface 32d of the covering plate 32. The second member 22b extends inward by a dimension at least longer than the maximum radius R of the roll paper 18. The maximum radius R of the roll paper 18 is when the roll paper 18 is in its unopened state. The second member 22b may be fixed to the lower surface 32d of the covering plate 32 with screws or the like.

[0026] The third member 22c extends downward from the tip of the second member 22b. The third member 22c has dimensions that are at least longer than the maximum radius R of the roll paper 18 in the vertical direction. A roll support shaft 25 is attached to the lower end of the third member 22c, extending rearward (towards the toilet bowl 12) in the front-rear direction. The roll support shaft 25 is a cylindrical member and has a diameter that can support the roll paper 18.

[0027] The covering portion 24 and the extension portion 26 are arranged side by side in the front-to-back direction, forming a covering plate 32 that extends from the side wall 14L toward the interior of the room. In this embodiment, the covering plate 32 is made up of a single rectangular plate member. That is, the covering portion 24 and the extension portion 26 are integrated. When viewed from above, the covering plate 32 extends toward the interior of the room to the extent that at least the entire roll of paper 18 is hidden. Similarly, when viewed from above, the covering portion 24 extends in the front-to-back direction to the extent that the roll of paper 18 is hidden. Therefore, when the covering plate 32 is viewed from above, the entire roll of paper 18 is covered by the covering portion 24.

[0028] The upper surface 26u of the extension 26 is positioned below a preset reference height, which is the eye level of the user of the toilet 12. The reference height may be set to a lower limit within the range of eye levels that the user can anticipate. As a result, the extension 26 is interposed between the user's line of sight and the lighting 28, preventing the light from the lighting 28 from directly entering the user's eyes. Here, since the user's awakening during the night is triggered by the light from the lighting 28 directly entering the user's eyes, the extension 26 helps to suppress the user's awakening during the night.

[0029] A light source, a light fixture 28, is attached to the lower surface 26d of the extension 26. The type of light fixture 28 is not limited as long as it emits light, such as an LED or a halogen lamp. The light fixture 28 emits light downward from the extension 26. The light fixture 28 supplies light to the restroom 10, for example, when the power to the main light fixture (not shown) installed in the ceiling of the restroom 10 is turned off. The power of the light fixture 28 can be turned on or off according to the opening and closing of the restroom door 16 or the presence of a user in the restroom 10.

[0030] The lateral restrictor 30 is provided to restrict the light from the lighting 28 that is directed away from the side wall 14L. The lateral restrictor 30 is a plate-like member with a predetermined thickness, formed in a rectangular shape when viewed from the direction of arrow B (front direction) in Figure 1. The lateral restrictor 30 extends downward from the tip of the extension 26. The lower end of the lateral restrictor 30 may extend below the lower end of the roll paper 18.

[0031] The extension portion 26 and the lateral restricting portion 30 are connected via a hinge 34. This allows the lateral restricting portion 30 to rotate relative to the extension portion 26, with the pivot support portion 34a of the hinge 34 acting as a fulcrum.

[0032] A mirror 36 is attached to the surface of the lateral restricting section 30 facing the side wall 14L. The mirror 36 reflects the light emitted from the illumination 28 and directs it toward the side wall 14L (including the area below the paper holder 20).

[0033] A downward restricting section 38 is connected to the lower end of the lateral restricting section 30. The downward restricting section 38 extends vertically from the surface of the lateral restricting section 30 that faces the side wall 14L. Therefore, the downward restricting section 38 is provided below the lighting fixture 28, with a gap formed between it and the lighting fixture 28. The downward restricting section 38 extends to a position where it contacts the side wall 14L. As a result, the area below the lighting fixture 28 is covered by the downward restricting section 38, thereby restricting the light guided downward from the lighting fixture 28 and the light reflected by the mirror 36 and guided downward.

[0034] The position Psu of the upper surface 38u of the lower restricting section 38, which faces the illumination 28, is set to be above the lowest end position Plmax of the roll paper 18 held by the holder 22, when the ground G is used as a reference.

[0035] A cushioning sheet 39 made of urethane foam or the like is attached to the part of the lower restricting section 38 that comes into contact with the side wall 14L. The cushioning sheet 39 mitigates the shock when the lower restricting section 38 collides with the side wall 14L.

[0036] An internal space SP is formed below the extension 26. The internal space SP is enclosed by the side wall 14L, the extension 26, the downward restricting section 38, the first opening 40, and the second opening 42. The first opening 40 is located behind the internal space SP. That is, the first opening 40 is positioned in the front-rear direction between the covering section 24 and the extension 26, in other words, between the roll paper 18 and the lighting 28, and opens toward the covering section 24.

[0037] The second opening 42 is located in front of the interior space SP. That is, within the restroom 10, the second opening 42 is located on the entrance side (front side) of the first opening 40, separated by the lighting 28; in other words, it is located at the position furthest from the toilet 12 (user) among the paper holder 20. The second opening 42 opens into the interior space SP in the front-to-back direction, away from the toilet 12. At this time, as shown in Figure 1, within the restroom 10, the arrangement from the entrance side to the back side is in the order of the second opening 42, lighting 28, first opening 40, roll paper 18, and toilet 12 (user).

[0038] As shown in Figure 2, when viewing the first opening 40 from the covering portion 24 along the direction in which the extended portion 26 extends (front-to-back direction), the holder 22 is positioned such that at least a portion of the roll paper 18 overlaps the first opening 40. In other words, the holder 22 is positioned such that at least a portion of the first opening 40 is closed by the roll paper 18 while the roll paper 18 is held by the holder 22.

[0039] The downward restricting section 38 may be provided with an adjustment mechanism 46 for adjusting the area of ​​the opening that allows light from the illumination 28 to pass through.

[0040] Figure 4 is a cross-sectional view of the paper holder 20 in Figure 3, obtained by cutting along the cutting line C. The adjustment mechanism 46 includes a first plate support member 48a and a second plate support member 48b arranged on both sides of the lower restricting portion 38 in the left-right direction, a fixed dimming plate 50 fixed immovably to the first plate support member 48a and the second plate support member 48b, and a movable dimming plate 52 that is relatively movable in the front-rear direction relative to the first plate support member 48 and the second plate support member 48b. The fixed dimming plate 50 is positioned above the movable dimming plate 52.

[0041] The first plate support member 48a is positioned on the left side in the left-right direction, that is, on the side wall 14L side. A cushioning sheet 39 is attached to the surface of the first plate support member 48a that abuts against the side wall 14L. The second plate support member 48b is positioned on the right side in the left-right direction, that is, on the side of the lateral restricting portion 30 side.

[0042] The fixed dimming plate 50 is immovably supported on both sides in the left-right direction by the first plate support member 48a and the second plate support member 48b. The fixed dimming plate 50 has at least one opening 50a (Figure 5) that opens when viewed from the top or bottom direction.

[0043] The movable dimming plate 52 is supported at both ends in the left-right direction by the first plate support member 48a and the second plate support member 48b, allowing it to move in the front-rear direction. For example, the first plate support member 48a and the second plate support member 48b each have slide grooves formed along the front-rear direction, and both ends of the movable dimming plate 52 fit into these slide grooves. This allows the movable dimming plate 52 to move in the front-rear direction.

[0044] The movable dimming plate 52 has at least one opening 52a (Figure 5) that opens when viewed from above or below. The movable dimming plate 52 also has a dimming knob 54 that the user operates when moving the movable dimming plate 52 in the front-back direction. The dimming knob 54 is formed on the lower side when the movable dimming plate 52 is supported by the first plate support member 48a and the second plate support member 48b.

[0045] Figure 5 shows the fixed dimming plate 50 and the movable dimming plate 52 viewed from above and below. Figure 5(a) shows a state in which no light from the lighting 28 leaks downward. Figure 5(b) shows a state in which some of the light from the lighting 28 leaks downward. Figure 5(c) shows a state in which the amount of light leaking downward from the lighting 28 is set to the maximum value adjustable by the adjustment mechanism 46. In Figures 5(a) to 5(c), the fixed dimming plate 50 and the movable dimming plate 52 are shown offset vertically for convenience, but in reality, as shown in Figure 4, these fixed dimming plate 50 and movable dimming plate 52 are arranged to overlap.

[0046] In Figure 5, two rectangular openings 50a are formed in the fixed dimming plate 50, and two rectangular openings 52a are formed in the movable dimming plate 52. The number of openings 50a and 52a is not limited to two and may be changed as appropriate. Also, although the areas of openings 50a and 52a are the same, their areas may be different.

[0047] As shown in Figure 5(a), when the light from the illumination 28 does not leak downwards, the region s1 formed by the opening 50a and the region s2 formed by the opening 52a do not overlap at all in the vertical direction. At this time, the area of ​​the opening through which the light from the illumination 28 can move downwards through the adjustment mechanism 46 becomes zero, and no light is emitted downwards from the downward restricting section 38.

[0048] Figure 5(b) shows the state when the movable dimming plate 52 is moved backward to a predetermined position from the state shown in Figure 5(a). In the state shown in Figure 5(b), as the movable dimming plate 52 moves, the opening 52a moves relative to the opening 50a of the fixed dimming plate 50, and a portion of the area s1 of the opening 50a and the area s2 of the opening 52a overlap. Specifically, the openings 50a and 52a overlap by the area (passage area) of the dashed line in area s2 of Figure 5(b). At this time, the light from the illumination 28 can move downward through the dashed area of ​​the opening 52a, and can illuminate the area below the downward restricting section 38. Furthermore, the larger the passage area through which the light from the illumination 28 can pass, the greater the amount of light that passes through the downward restricting section 38 and illuminates the area below. Therefore, by adjusting the position of the movable dimming plate 52, the amount of light illuminating the area below from the downward restricting section 38 can be adjusted.

[0049] Figure 5(c) shows the state when the user moves the movable dimming plate 52 to its furthest rear position. In the state shown in Figure 5(c), the area s1 of the opening 50a and the area s2 of the opening 52a completely overlap. At this time, the area through which the light from the illumination 28 can pass is maximized, and the amount of light from the illumination 28 that passes through the downward restricting section 38 and illuminates downwards is maximized.

[0050] As explained in Figures 5(a) to 5(b) above, by adjusting the relative position of the movable dimming plate 52 with respect to the fixed dimming plate 50, the area of ​​the opening through which the light from the lighting 28 can pass can be adjusted in the adjustment mechanism 46. As a result, the amount of light that passes through the downward restricting section 38 and illuminates downwards can be adjusted, thereby allowing the brightness inside the restroom 10 to be adjusted.

[0051] Furthermore, the lateral restricting section 30 may also be provided with an adjustment mechanism 46. Alternatively, the lateral restricting section 30 may be provided with an adjustment mechanism 46 instead of the downward restricting section 38. In other words, at least one of the lateral restricting section 30 and the downward restricting section 38 may be provided with an adjustment mechanism 46. This allows the brightness of the restroom 10 to be adjusted as appropriate by adjusting at least one of the light intensity of the lighting 28 passing through the lateral restricting section 30 and the light intensity of the lighting 28 passing through the downward restricting section 38.

[0052] [Mechanism of Action and Effects] In the restroom 10 configured as described above, at night, users may enter the restroom 10 with the power to the main light (not shown) installed on the ceiling of the restroom 10 turned off. In this case, for example, when the door 16 of the restroom 10 opens, light from the light fixture 28 is shone from the lower surface of the extension 26. The light shone from the light fixture 28 toward the interior is shone onto the lateral restrictor 30. The light shone onto the lateral restrictor 30 is reflected by the mirror 36 and shone onto the side wall 14L. As a result, the light from the light fixture 28 toward the interior is blocked by the lateral restrictor 30. In addition, the light shone downwards from the light fixture 28 is blocked by the downward restrictor 38.

[0053] Furthermore, some of the light emitted from the lighting 28 passes through the first opening 40 and the second opening 42 and is emitted to the outside of the internal space SP. At this time, some of the light from the lighting 28 spreads through the first opening 40 along the axial direction of the roll paper 18 (towards the rear). However, the roll paper 18 is positioned adjacent to the first opening 40, and most of the first opening 40 is covered by the roll paper 18. Therefore, most of the light passing through the first opening 40 is blocked by the roll paper 18, and the amount of light emitted to the outside of the paper holder 20 through the first opening 40 is limited. As a result, a small amount of light leaks into the restroom 10, which suppresses the user from waking up in the middle of the night, while the user's safety is ensured because they can perceive the location of the toilet 12. In particular, since the position Psu of the upper surface 38u of the lower restricting portion 38 is located above the lowest end position Plmax of the roll paper 18, the area of ​​the first opening 40 that can pass through is further narrowed, and the light irradiated toward the toilet bowl 12 through the first opening 40 is effectively restricted by the roll paper 18. As a result, the amount of light passing through the first opening 40 is limited, and therefore the amount of light irradiated directly upon the user is limited. Consequently, it is possible to suppress the user from waking up in the middle of the night due to the light irradiated from the first opening 40. When the amount of roll paper 18 remaining decreases, the amount of light spreading backward increases, but since the covering portion 24 covers the top of the roll paper 18, the light is prevented from reaching upward, i.e., directly into the user's eyes. Also, when the amount of roll paper 18 remaining is small, the roll paper 18 is illuminated relatively brightly, so even a user who is not fully conscious can be made aware that there is little left.

[0054] On the other hand, since there is nothing obstructing the second opening 42 in front, the light from the lighting 28 passes through the second opening 42 and shines through it. However, since the second opening 42 is located away from the user, the light shines from the second opening 42 but is unlikely to shine directly on the user. This allows the restroom 10 to be brightly illuminated using the light from the lighting 28 that shines through the second opening 42, while suppressing the user from waking up in the middle of the night.

[0055] As described above, by suppressing the direct illumination of the user by the light emitted from the lighting 28, it is possible to suppress the user from waking up in the middle of the night. In addition, since the light from the lighting 28 passing through the first opening 40 illuminates the roll paper 18, the visibility of the roll paper 18 can be improved. Furthermore, by utilizing the light from the lighting 28 passing through the second opening 42, which is less likely to directly illuminate the user, the restroom 10 can be illuminated at a predetermined brightness.

[0056] Furthermore, since an adjustment mechanism 46 is provided in at least one of the lateral restricting section 30 and the downward restricting section 38, the brightness inside the restroom 10 can be appropriately adjusted by adjusting the adjustment mechanism 46 as needed to adjust the area through which the light from the lighting 28 passes.

[0057] [Other uses] Since the lateral restricting portion 30 of the paper holder 20 is connected to the extension portion 26 via a hinge 34, the lateral restricting portion 30 can be rotated using the pivot support portion 34a of the hinge 34 as a fulcrum, thereby transforming the paper holder 20 into the state shown in Figure 6. Figure 6 shows another mode of use of the paper holder 20, and is a view of the paper holder 20 from the rear side of the restroom 10. Note that the holder 22 and the roll of paper 18 are omitted in Figure 6.

[0058] As shown in Figure 6, the lateral restricting portion 30 is rotated until the end face 26x of the extension portion 26 in the direction facing the interior comes into contact with the end face 30x of the lateral restricting portion 30. In this state, the outer wall surface 30u of the lateral restricting portion 30 is adjusted to be flush with the upper surface 26u of the extension portion 26. Specifically, the thickness 26t of the extension portion 26 and the thickness 30t of the lateral restricting portion 30 are the same.

[0059] Furthermore, a holding mechanism 60 is provided between the extended portion 26 and the lateral restricting portion 30, which holds the end face 26x of the extended portion 26 and the end face 30x of the lateral restricting portion 30 in contact with each other.

[0060] The holding mechanism 60 comprises a first slide rail 62, a second slide rail 64, and a fixing rod 66. Figure 7 is a diagram illustrating the structure of the holding mechanism 60. Figure 7(a) is a perspective view showing the first slide rail 62, the second slide rail 64, and the fixing rod 66 in an disassembled state. Figure 7(b) is a perspective view showing the holding mechanism 60 when the extension portion 26 and the lateral restricting portion 30 are held in the state shown in Figure 6.

[0061] The first slide rail 62 is fixed to the extension 26. The first slide rail 62 is formed in a longitudinal shape, and its longitudinal direction is aligned with the direction (left-right direction) in which it extends into the interior of the extension 26.

[0062] The second slide rail 64 is fixed to the lateral restrictor 30. The second slide rail 64 is formed in a longitudinal shape, and its longitudinal direction is aligned with the direction (left-right direction) in which the lateral restrictor 30 extends into the interior of the room in the state shown in Figure 6.

[0063] The first slide rail 62 has a C-shaped cross-section and a first rail groove 68 formed inside along its longitudinal direction. Similarly, the second slide rail 64 has a C-shaped cross-section and a second rail groove 70 formed inside along its longitudinal direction. The first rail groove 68 and the second rail groove 70 are formed to have the same shape when viewed from the longitudinal direction. Furthermore, when the end face 26x of the extension portion 26 and the end face 30x of the lateral restricting portion 30 are in contact as shown in Figure 6, the first rail groove 68 and the second rail groove 70 are adjusted to be continuously connected.

[0064] The fixing rod 66 is a longitudinal member with a rectangular cross-section. The cross-section of the fixing rod 66 is the same shape as the first rail groove 68 and the second rail groove 70 when viewed from the longitudinal direction. As shown in Figures 6 and 7(b), the fixing rod 66 is inserted into the first rail groove 68 and the second rail groove 70 in a slidable state. The fixing rod 66 is provided with a fixing rod handle 66a that protrudes outward from the first slide rail 62 and the second slide rail 64. When sliding the fixing rod 66, the user grasps the fixing rod handle 66a and slides the fixing rod 66.

[0065] When switching the paper holder 20 to the state shown in Figure 6, the user rotates the lateral restrictor 30 to the position shown in Figure 6 and slides the fixing rod 66 toward the first slide rail 62. At this time, the fixing rod 66 straddles both the first slide rail 62 and the second slide rail 64 (Figures 6 and 7(b)), and the rotation of the lateral restrictor 30 is prevented by the fixing rod 66. When switching the paper holder 20 from the state shown in Figure 6 to the state shown in Figure 2, the user moves the fixing rod 66 toward the second slide rail 64. When the fixing rod 66 moves into the second slide rail 64, the rotation of the lateral restrictor 30 is permitted, and the lateral restrictor 30 is rotated to switch to the state shown in Figure 2.

[0066] In the configuration shown in Figure 6, when the top surface of the paper holder 20 is used as a storage area, the area of ​​the top surface becomes the sum of the area of ​​the top surface 26u of the extension 26 and the area of ​​the outer wall surface 30u of the lateral restricting section 30, thus increasing the usable area for storage. In addition, in the configuration shown in Figure 6, the illumination area of ​​the lighting 28 is widened, so if the restroom 10 is dark, the restroom 10 can be brightened by configuring it as shown in Figure 6.

[0067] As described above, embodiments illustrating the technology of this disclosure have been explained. However, the technology in this disclosure is not limited to these embodiments and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to combine the components described in the above-mentioned embodiments to create new embodiments. Therefore, examples of modifications are given below.

[0068] [Differentiation] In the above embodiment, a downward restricting section 38 was provided to restrict the downward guidance of light from the lighting 28, but the downward restricting section 38 may be omitted. Omitting the downward restricting section 38 has the effect of illuminating the floor inside the restroom 10, thereby ensuring the safety of the user. In particular, when the reflected light from the mirror 36 placed in the internal space SP illuminates the side wall 14L, the floor inside the restroom 10 is illuminated more brightly. Even if the downward restricting section 38 is omitted, the light from the lighting 28 only illuminates downwards, so the user is hardly directly exposed to the light from the lighting 28. Therefore, even if the downward restricting section 38 is omitted, the effect of suppressing the user's awakening in the middle of the night can be obtained.

[0069] In the above embodiment, the lighting 28 was provided on the lower surface 26d of the extension 26, but the disclosure is not limited thereto. For example, the lighting 28 may be mounted at a predetermined distance below the extension 26. In this case, the lighting 28 may be mounted on, for example, the side wall 14L. That is, the mounting position of the lighting 28 is not particularly limited, as long as it is provided below the extension 26 and illuminates the internal space SP formed below the extension 26. Furthermore, the mounting position of the mirror 36 may also be appropriately changed according to the mounting position of the lighting 28.

[0070] In the above embodiment, an adjustment mechanism 46 was provided in at least one of the lateral restricting portion 30 and the downward restricting portion 38, but the embodiment may be carried out without the adjustment mechanism 46.

[0071] In the above embodiment, the covering portion 24 and the extension portion 26 were made of a single plate member, but the covering portion 24 and the extension portion 26 may be made of separate members.

[0072] In the above embodiment, the paper holder 20 was provided on the side wall 14L located on the left side of the restroom 10, but it may also be provided on the side wall 14R located on the right side of the restroom 10.

[0073] In the above embodiment, a mirror 36 was attached to the surface of the lateral restricting portion 30 facing the side wall 14L, but this disclosure does not necessarily require the mirror 36. That is, the mirror 36 attached to the lateral restricting portion 30 may be removed.

[0074] In the above embodiment, the lateral restricting portion 30 was configured to be rotatable relative to the extension portion 26, but the lateral restricting portion 30 may be made non-rotatable relative to the extension portion 26. That is, the lateral restricting portion 30 may be fixed relative to the extension portion 26 in the position shown in Figure 2. In this case, the paper holder will not switch to the state shown in Figure 6, and therefore the holding mechanism 60 will not be necessary.

[0075] In the above embodiment, a second opening 42 was formed that opened the internal space SP below the extension 26 in a direction away from the toilet bowl 12. However, the second opening 42 may be omitted. That is, by providing a partition wall or the like that closes the second opening 42, the light from the lighting 28 that is irradiated in a direction away from the user may be blocked.

[0076] In the above embodiment, the holder 22 was fixed to the side wall 14L with screws or the like, but the holder 22 may also be fixed to the covering plate 32 with screws or the like. In this case, the first member 22a of the holder 22 can be omitted. Even when the holder 22 is fixed to the covering plate 32, the holder 22 is provided on the side wall 14L via the covering plate 32, so the holder 22 is substantially provided on the side wall 14L.

[0077] Furthermore, an air freshener that suppresses the user waking up in the middle of the night may be installed in the restroom 10. This can further suppress the user waking up in the middle of the night. Alternatively, the air freshener may be placed on top of the covering plate 32.

[0078] (Effects, etc.) Based on the above, the restroom of this disclosure has the following features and provides the following effects.

[0079] (Technology 1) The restroom of the present disclosure comprises a toilet bowl, a side wall provided to the side of the toilet bowl, a covering plate having a covering portion extending from the side wall toward the room and an extension portion extending from the covering portion toward the direction away from the toilet bowl, a holder provided below the covering portion for holding a roll of paper, a light source provided below the extension portion, and a lateral restricting portion extending downward from the extension portion to restrict the light from the light source from being directed toward the side wall, wherein a first opening is formed between the side wall, the extension portion and the lateral restricting portion to open the space below the extension portion toward the covering portion, and the holder is positioned such that the roll of paper overlaps the first opening when viewed from the covering portion toward the first opening along the direction in which the extension portion extends.

[0080] According to the toilet of Technology 1 described above, it has a lateral restricting section that extends downward from the extended section, and the roll paper is positioned so that it overlaps with the first opening when viewed from the covering section. As a result, the light from the light source is blocked by the lateral restricting section and the roll paper. This prevents the light from the light source from directly shining on the user using the toilet, thus preventing the user from waking up in the middle of the night due to direct light from the light source. In addition, since the roll paper is illuminated by the light from the light source, the visibility of the roll paper is improved.

[0081] (Technology 2) In the restroom of the above-described technology 1, a downward restricting portion is further provided below the light source, with a gap formed between it and the light source, and restricts the downward guidance of light from the light source, and the upper surface of the downward restricting portion may be set to be above the lowest end position of the roll paper held by the holder.

[0082] According to the restroom of the above technology 2, the downward restricting section can restrict the light irradiated downward from the light source. Furthermore, by narrowing the area of ​​the first opening formed between the side wall, the covering plate, and the lateral restricting section with the downward restricting section, the light irradiated from the light source toward the toilet bowl through the first opening can be more effectively restricted by the roll paper.

[0083] (Technology 3) In the restroom of the above-described technology 1 or technology 2, at least one of the lateral restricting portion and the downward restricting portion may be provided with an adjustment mechanism for adjusting the area of ​​the opening for allowing light from the light source to pass through.

[0084] According to the restroom of the above technology 3, the amount of light irradiated from at least one of the sides and below can be adjusted by adjusting the area of ​​the opening using an adjustment mechanism as needed, thereby adjusting the brightness inside the restroom.

[0085] (Technology 4) In any of the restrooms described in Technology 1 to Technology 3 above, a second opening may be formed between the side wall, the extension, and the lateral restricting portion, which opens the space below the extension in a direction away from the toilet.

[0086] According to the restroom of the above technology 4, by allowing light to be directed in a direction that is unlikely to be directly shone on the toilet user, the restroom can be brightly illuminated while suppressing the user from waking up in the middle of the night.

[0087] (Technology 5) In any of the restrooms described in the first to fourth technologies above, the extension may be installed below a predetermined standard height, which is the eye level of the toilet user.

[0088] According to the restroom of the above technology 5, an extension is interposed between the user's line of sight and the light source, which effectively suppresses the user from waking up in the middle of the night. [Explanation of Symbols]
