<First Embodiment>
A bathroom door 1 shown in FIGS. 1A and 1B includes a frame body 2 fixed to a building frame and a shoji 3 provided inside the frame body 2. Moreover, the bathroom door 1 in the illustrated example is provided with a panel 4 such as frosted glass fitted in one half, and is opened and closed by the shoji 3 with the remaining half on the one side as an entrance. The shoji 3 is a sliding door incorporating a panel 5 such as frosted glass.

  The frame 1 includes an upper frame 6, left and right collar frames 7, 7, and a lower frame 8. The lower frame 8 constituting the frame body 1 is provided with a slope 9 inclined downward toward the bathroom. As shown in FIG. 2, the lower frame 8 includes a main body member 10 and a rail member 11 that guides the shoji 3, and the main body member 10 includes a support piece 10 </ b> A that extends toward the bathroom. A slope 9 is attached via a fixture 12 screwed to the support piece 10A.

  In the bathroom door 1, as shown in FIG. 3, at least the surface (upper surface) of the slope 9 is formed of a main body material region A and a different material region B made of a different material from the main body material region A. . The body material region A and the different material region B have different water repellency. In this embodiment, the dissimilar material region B has a greater water repellency than the main body material region A.

  More specifically, the slope 9 has an engaging portion 9A to the protruding piece 10B of the main body member 10 at the end on the upper side of the slope in the cross section shown in FIG. 3, and is fixed to the lower surface of the intermediate portion. It has a fixed piece 9B that engages with the tool 12, and has a groove portion 9C that is opened downward at the end of the inclined lower side. Resin fins F that come into contact with the bathroom floor are attached to the groove 9C.

  Further, the slope 9 has two mounting grooves 9D and 9D opened upward at a predetermined interval on the lower side of the central portion in the inclined direction, and fine drainage on the surface (upper surface). Grooves 9G are formed at predetermined intervals in the inclination direction. The slope 9 has a configuration in which different members 13 and 13 are provided in the mounting grooves 9D and 9D.

  The upper frame 6, the left and right collar frames 7, 7, and the lower frame 8 constituting the frame body 2 are made of an aluminum alloy, for example, and are extruded. Therefore, the lower frame 8 has the slope 9, the main body member 10, and the rail member 11 along the longitudinal direction. The slope 9 is a separate member from the main body member 10 and is similarly formed of a shape material, and has an engaging portion 9A, a fixing piece 9B, a groove portion 9C, and mounting grooves 9D and 9D in the longitudinal direction.

  The dissimilar member 13 is a long member made of synthetic resin, and fine protrusions 13T for preventing slip are formed on the surface (upper surface) at predetermined intervals in the inclination direction. The dissimilar member 13 has a fixing leg piece 13A on the lower surface, and the leg piece 13A is inserted in the longitudinal direction from the end of the attachment groove 9D of the slope 9. As a result, the dissimilar member 13 is mounted on the slope 9 without being easily detached, and the surface thereof is connected to the surface of the slope 9 in substantially the same plane. Further, as shown in FIG. 3, a cap 14 for closing the fore edge is attached to the end of the slope 9.

  The slope 9 having the above configuration has a main body material region A made of the main material (aluminum alloy) of the slope 9 on the upper side of the slope on the surface, and a dissimilar material different from the main material on the lower side of the slope ( It has two different material regions B and B made of different members 13) made of synthetic resin in parallel. That is, the dissimilar material region B is arranged inside the bathroom from the central portion of the prospective direction (inclination direction) of the slope 9.

  At this time, the dissimilar material region B is provided over the left-right direction of the slope. The body material region A is also between the two different material regions B and B. Thus, the slope 9 is configured such that the main body material regions A and the dissimilar member regions B are alternately arranged in the inclination direction, that is, the direction orthogonal to the longitudinal direction of the lower frame 8.

  Here, it is well known that the synthetic resin has higher water repellency than the aluminum alloy. Therefore, the surface of the slope 9 is configured to have higher water repellency in the dissimilar material region B than in the main body material region A. In other words, the surface 9 of the slope 9 is hydrophobic in both regions A and B, but the water contact angle in the dissimilar member region B is more than the water contact angle in the main body material region A. It is a big configuration.

  The bathroom door 1 having the above configuration eliminates the level difference at the entrance of the bathroom by the slope 9 that slopes downward toward the bathroom side, and causes the water to flow toward the bathroom side by the inclination. At this time, the bathroom door has a main body material region A and a different material region B having different water repellency on the surface of the slope 9 when water is to remain on the surface of the slope 9. This breaks the balance of the surface tension of residual water and destroys water droplets. In other words, the formation of water droplets is prevented. Thereby, water flows down without remaining.

  In this way, the bathroom door 1 can improve the drainage of the slope 9, thereby enabling the surface of the slope 9 to be quickly dried and obtaining a safe and hygienic state. Can do.

  In addition, the bathroom door 1 is provided with the dissimilar material region B extending in the left-right direction of the slope 9, so that the boundary between the main body material region A and the dissimilar material region B also exists along the left-right direction of the slope 9. become. As a result, the bathroom door 1 can prevent the formation of residual water over the entire surface of the slope 9, can further enhance the drainage of the slope 9, and further, the dissimilar material forming the dissimilar material region B 13 also improves the anti-slip function.

  Furthermore, in the slope 9 inclined at a gentle angle, water tends to remain on the lower side of the inclination. On the other hand, the bathroom door 1 described above arranges two different material regions B on the slope lower side of the slope 9 at a predetermined interval, thereby allowing water that tends to remain on the slope lower side to flow down. The surface can be quickly dried.

  Further, the slope 9 has a plurality (two in the illustrated example) of main body material regions A and a plurality (two in the illustrated example) of different member regions B alternately arranged in the inclination direction. As a result, the slope 9 secures many boundaries between the two regions A and B that destroy the water droplets, and also destroys the water droplets by the drainage grooves 9G in the body member region A and the grooves between the protrusions 13T in the different member region B. And can further improve drainage.

  Further, in the slope 9, the dissimilar material region B is arranged inside the bathroom with respect to the central portion of the prospective direction (inclination direction) of the slope 9. As a result, the slope 9 has high water repellency inside the bathroom where water tends to remain, and combined with the effect of destroying the water droplets at the boundary between the two regions A and B, further improves the drainage performance against the flowing water droplets. To realize.

  4 and 5 are cross-sectional explanatory views each showing an example of the arrangement of grooves in the slope constituting the bathroom door 1. The slope 9 which shows the principal part in each figure has the main body material area | region A which consists of a main body material (aluminum alloy) in the inclination upper side of the surface (upper surface), and the dissimilar member which consists of the dissimilar member 13 in the lower side. Region B is included. As described above, the slope 9 has a plurality of drain grooves 9G arranged in parallel in the left-right direction. On the other hand, the dissimilar member 13 has a plurality of protrusions 13T that are also arranged in parallel in the longitudinal direction. The dissimilar member 13 forms a drain groove 13G extending in the longitudinal direction between the protrusions 13T.

  In the slope 9 shown in FIG. 4, the pitch P1 of the drainage groove 9G in the main body material region A and the pitch P2 of the drainage groove 13G in the different material region B (different material 13) are different from each other. Then, the pitch P2 of the drain grooves 13G of the different member 13 is smaller (P1> P2). The pitches P1 and P2 are intervals between the center lines of the adjacent mounting grooves 9G and 13G.

  The slope 9 has a structure in which the bottom surface of the drainage groove 13G of the dissimilar member 13 is positioned above the surface of the main body portion of the slope 9. In addition, the upper surface of the cap 14 indicated by an imaginary line in the figure is continuous with the slope 9. As a result, the drainage groove 13G of the dissimilar member 13 is opened at the end on the cap 14 side, and the water drainage is good.

  In the slope 9 shown in FIG. 5, the dissimilar member 13 has drainage grooves 13G at the same pitch P1 as the drainage grooves 9G of the slope 9, and drainage grooves at smaller pitch P3 on both sides thereof, that is, on the inclined upper side and the inclined lower side. 13G.

  Each of the slopes 9 described above has a function of destroying and flowing down water droplets at the boundary between the main body material region A and the dissimilar material region B, and the water droplets flowing down by the drain grooves 9G and 13G provided in the longitudinal direction. Since the destructive effect is also obtained, it is possible to realize further improvement of drainability.

  Further, the slope 9 is different from the pitch P1 of the drainage groove 9G in the main body material region A and the pitch P2 of the drainage groove 13G in the different material region B, and from the pitch P1 of the drainage groove 9G in the main body material region A. However, since the pitch P2 of the drainage grooves 13G in the different material region B (the different member 13) is reduced, the number of the protrusions 13T increases in the small pitch portion compared to the large pitch portion. The anti-slip function can be enhanced by increasing the frictional force when contacting the portion.

  Further, the slope 9 has drainage grooves 13G having different pitches 13 at the same pitch P1 as the drainage grooves 9G in the main body material region A. The slope 9 has a smaller pitch P3 on the upper slope side and lower slope side of the drainage groove 13G. It has a drainage groove 13G. As a result, for the water droplets that could not be destroyed by the narrow drainage groove 13G on the upper slope side, the waterdrops should flow smoothly through the wide drainage groove 13G on the lower side, and further destroy the waterdrops in the narrow drainage groove 13G on the lower side Thus, further improvement of the draining function can be realized.

  Further, the slope 9 has a structure in which the bottom surface of the drainage groove 13G of the dissimilar member 13 is positioned above the surface of the main body portion of the slope 9, so that a step is generated between the main body material region A and the dissimilar material region B. By this step, a water droplet destruction effect can be obtained, and the drainage performance is further improved.

<Comparison experiment>
About the slope (9) of the bathroom door 1 demonstrated by the said embodiment, and the slope of a comparative example, the comparative experiment for confirming draining property was done. 6 to 9 are images obtained by photographing the watering and subsequent changes over time. In each figure, the left side is the slope of the above embodiment, and the right side is the slope of the comparative example. The slope of the comparative example is made of an aluminum alloy, and its surface is only the main body material region.

  FIG. 6 is an image when water is sprinkled on both slopes. FIG. 7 is an image 3 seconds after watering. From the image in FIG. 7, a large amount of residual water can be confirmed on the slope of the comparative example. On the other hand, in the slope of the embodiment, the residual water is obviously small, and it can be seen that the drainage is already good at this stage.

  FIG. 8 is an image after 8 seconds from watering. From the image of FIG. 8, residual water can be confirmed in several places in the slope of the comparative example. On the other hand, it can be seen that there is almost no residual water in the slope of the embodiment.

  And FIG. 9 is an image 15 seconds after watering. From the image in FIG. 9, it can be confirmed that in the slope of the comparative example, water that is desired to remain 8 seconds after watering (FIG. 8) remains as it is. On the other hand, it can be seen that the slope of the embodiment has no residual water and is almost dry.

  From the comparative experiment described above, it was found that the slope 9 of the bathroom door 1 of the above embodiment was extremely superior in draining performance as compared with the comparative example, and the surface was quickly dried to be safe and hygienic. It was confirmed that a sufficient state could be secured.

Second Embodiment
FIG. 10 is a diagram for explaining a second embodiment of a bathroom door according to the present invention. In this embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The illustrated bathroom door 1 has a basic configuration similar to that of the first embodiment. The main material of the slope 9 constituting the lower frame 8 is made of a metal such as an aluminum alloy, and has a wide mounting groove 9D. The dissimilar member 13 is made of synthetic resin, and has a pair of bowl-shaped leg pieces 13A and 13A on the lower surface thereof. The dissimilar member 13 is mounted by fitting both leg pieces 13A and 13A in the longitudinal direction from the end of the attachment groove 9D of the slope 9, and the surface thereof is connected to the surface of the slope 9 in substantially the same plane.

  The bathroom door 1 includes a main body material region (A) made of the main material (aluminum alloy) of the slope 9 and a different material (resinous member 13 made of resin) on the surface (upper surface) of the slope 9. The dissimilar member region (B) is formed, and the dissimilar member region has a higher water repellency (a larger contact angle with water) than the main body material region.

  Even in the bathroom door 1, as in the first embodiment, when water is to remain on the surface of the slope 9, the residual water at the boundary between the body material region and the dissimilar material region having different water repellency. The balance of surface tension is broken to destroy water droplets, and the water flows down along the slope. Thereby, the draining property of the slope 9 can be improved, the surface of the slope 9 can be quickly dried, and a safe and hygienic state can be obtained.

  Note that the details of the configuration of the bathroom door according to the present invention are not limited to the above-described embodiments, and can be changed as appropriate without departing from the gist of the present invention. For example, if the main material of the slope and the material of the different member have different water repellency and can satisfy the strength and resistance of the slope, various materials other than aluminum alloy and synthetic resin should be used. Can do.

  Moreover, although each said embodiment demonstrated the structure which has arrange | positioned two or one dissimilar member over the left-right direction to the slope, arrangement | positioning of a dissimilar member is various. For example, a plurality of dissimilar members may be arranged at predetermined intervals over the entire surface of the slope, and in addition, dissimilar members having an appropriate length may be arranged in a broken line shape or alternately on the left and right. At this time, since the different member also has a function as a slip stopper, it is more desirable to dispose the member in the longitudinal direction of the slope. Further, the dissimilar member region is not limited to being formed by the dissimilar member attached to the slope body, and may be formed by a dissimilar material that is adhered to or applied to the surface of the slope. Furthermore, drainage grooves and protrusions of various forms can be provided in various arrangements in the main body material region and the different material region of the slope.
