Description

  The present invention relates to the structure of a urinal installed in a male toilet and the arrangement of urinals in a toilet in which a plurality of urinals are arranged.

  Conventionally, toilets for standing urinals for men include a wall-mounted type, a floor-mounted type, and an embedded type, which are equipped with push buttons and human sensors, and are adapted to allow washing water to flow manually or automatically. As for any toilet bowl shape, as shown in FIG. 7, the width direction center of the toilet body 2 of the urinal 1 has a flat surface or a concave surface, but the center in the width direction of the inner wall surface 3 that receives the urine is tangent to the inner wall surface 3. On the other hand, the urine is formed symmetrically with respect to the center of the toilet body 2 so that the urine hits at a right angle.

  However, in conventional urinals, when men of different ages and heights urinate into the urinal, there are individual differences in the height, momentum, and volume of urination, so that the urine flows down on the inner wall of the toilet body. However, the urine splashed out of the toilet bowl was sprayed as fine water droplets, and urine splashed on the trousers, legs, and shoes, and the floor surface in front of the toilet bowl became dirty with urine.

  One way to solve this problem is to make it easier to urinate the urine at the ideal position in the toilet bowl. It is known that a design or a target object is displayed and urinated so that a urine is intentionally hit at the position, thereby preventing the reduction of splashes and dirt in the toilet (for example, see Patent Document 1).

  In addition, as a user's own effort, the urine is not intentionally urinated to the center of the inner wall of the urinal, and the urine is released by aiming at the side where the inner wall surface outside the center is inclined from the front to the back. May attempt to reduce splashing.

  Furthermore, in toilets such as restaurants, a large amount of ice is placed in the urinal, so that urine can enter and buffer the gaps between the ice when urinating, and the urine temperature close to body temperature melts the ice. In some cases, it is possible to reduce the scattering of urine by flowing while soaking in, while at the same time creating a sense of cleanliness.

  Also, as a urinal structure that prevents urine from scattering, the height of the urinal body is moved up and down according to the physique, and the urinal location that receives the urine is changed to prevent floor contamination due to urination Is also known (see, for example, Patent Document 2).

JP 2009-74300 A JP 2004-225370 A

  However, when the target of urination is displayed on the inner wall surface of the toilet as described above, the user does not always aim at the target and urinates, and the reliability of scattering prevention is not high. . Also, when a user intentionally urinates by aiming at a side off the center of the toilet inner wall, there are few users who perform such a troublesome urination method, and conversely, the urine bounces off the edge of the toilet bowl. There was a high risk of urinating outside the toilet. Furthermore, the method of putting ice in the toilet bowl is disadvantageous in that it consumes a large amount of ice and is uneconomical, and the toilet bowl is condensed and the surrounding area gets wet with condensed water.

  In addition, if the toilet body has a structure that moves up and down according to the physique of the user, it is necessary to provide a complicated vertical movement mechanism for each toilet, which is not practical in terms of mechanism and cost. Absent. Further, in order to set the optimal height for a person who urinates, it is necessary to provide complicated sensors and switches, and it is difficult to quickly complete the setting before urination. Furthermore, since there are many movable parts, there also exists a fault that it is easy to produce a failure.

  On the other hand, in places where multiple urinals are lined up, such as a public toilet, depending on the positional relationship between the entrance and the urinal, the entrance door may be opened during urination or in a public toilet where there is no door at the entrance, In a place where you are in sight or multiple urinals line up side by side, even if there are partition plates between the toilet bowls, you can easily see your neighbor's urination simply by turning your eyes to the left and right, protecting your privacy There is no problem.

  In large public toilets such as schools with many urinals, halls such as concert halls, movie theaters, and highway service areas, multiple urinals face the walls of the toilet room at regular intervals. It is installed to face the front and urinate. For this reason, it is possible to take the same direction for the urinal and the direction of the urinal in the left and right directions of the toilet. Hindering.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a urinal that can prevent urine from splashing outside the urinal without complicating the structure. .

  Further, in addition to the above object, the present invention provides a movement in which a urination state does not easily enter another person's field of view in a toilet in which a plurality of urinals are juxtaposed, and a person who goes to a urinal and a person who retreats even when crowded The purpose is to provide a toilet that can smooth the toilet.

  In order to achieve the above object, the present invention provides a urinal having an inner wall surface against which a urine hits a toilet body opening toward a user, wherein the inner wall surface of the toilet body is connected to a tangent to a central plane or curved surface portion in the width direction. Is formed asymmetrically so as to be inclined in the front-rear direction from one end side in the width direction of the toilet body to the other end side.

  Thereby, since the center in the width direction of the inner wall surface to which the urine hits is inclined, urination flows down along the inner wall surface without rebounding to the user side.

  Further, in the present invention, in addition to the above configuration, the inner wall surface of the toilet body has a shallow depth in the front-rear direction on one end side in the width direction of the toilet body and a deep depth in the front-rear direction on the other end side in the width direction. In addition, a convex curved surface and a concave curved surface that are continuous from one end side to the other end side in the width direction are formed.

  Thereby, since the said inner wall surface is formed from the convex curved surface and concave curved surface which continue from the width direction one end side to the other end side, it becomes possible to make the inclination angle of the width direction center part smaller.

  Moreover, in addition to the said structure, this invention forms the back surface of the toilet bowl main body fixed to the wall surface in a toilet room so that it may incline in the same direction as an inner wall surface.

  Thereby, since the back surface of the toilet bowl body is inclined in the same direction as the inner wall surface, the dimension between the inner wall surface and the back surface is reduced when the depth of the inner wall surface is shallow.

  Further, the present invention provides a toilet in which a plurality of the urinals are installed, wherein the urinals adjacent to each other are placed on the wall surface of the toilet so that the user of the urinal stands in the same left-right direction with respect to the wall surface of the toilet room. Installed diagonally.

  Thereby, when a user urinates to a urinal, since it stands diagonally facing the left-right same direction with respect to the wall surface in a toilet room, the positional relationship with which it is difficult to line up with an adjacent user is maintained.

  In the toilet, the toilet has a doorway on one wall side in the front-rear direction of the toilet room, and a plurality of the urinals are arranged in the front-rear direction on at least one wall surface side in the left-right direction in the toilet room, The urinals are installed diagonally so that the toilet body faces the entrance / exit side.

  As a result, the urinal body of the urinal is installed obliquely in the same direction on the left and right so that it faces the entrance / exit side, so when a person who is going to urinate is going from the entrance to the urinal, Thus, it is possible to smoothly stand in front of the urinal without greatly changing the direction of the body, so that urination can be started promptly. Further, since the user stands diagonally toward the wall in the toilet room, it is possible to move forward and backward with respect to the urinal without greatly detouring the user of the adjacent urinal.

  Further, the present invention provides the toilet, wherein the toilet room has an entrance on one wall side and the other wall side in the front-rear direction of the toilet room, and a plurality of the urinals are provided on both the left and right wall surfaces in the toilet room. A urinal placed on one wall side in the left-right direction in the toilet room is installed diagonally so that the toilet body faces the entrance / exit side on one wall side in the front-rear direction, and the other in the left-right direction in the toilet room A urinal disposed on the wall surface side of the toilet is installed obliquely so that the toilet body faces the entrance / exit side on the other wall side in the front-rear direction.

  As a result, a user who has entered from one entrance / exit side proceeds toward a urinal on one wall surface in the left / right direction facing toward himself / herself, and a user who enters from the other entrance / exit side is directed in the left / right direction toward himself / herself. In order to advance toward the urinal on the other wall surface side, the flow line of the user entering / exiting from one entrance / exit and the flow line of the user entering / exiting from the other entrance / exit are separated.

According to the urinal of the present invention, since urination flows down along the inner wall surface without splashing back to the user side, it is possible to prevent the clothes and the floor from being soiled due to the urine scattering outside the toilet. Thereby, it is not necessary to urinate toward the target so as not to scatter the urine, and it is not necessary to intentionally divert the direction of urination to the side, and urination can always be performed naturally. Furthermore, since the structure does not become complicated as in the conventional example in which the toilet body is moved up and down in accordance with the user's physique, there is no increase in manufacturing cost or failure . In addition, since the dimension between the inner wall surface and the back surface can be reduced when the depth of the inner wall surface is shallow, there is an advantage that the material cost of the urinal body can be reduced and the weight can be reduced accordingly. .

  Further, according to the toilet of the present invention, when the user urinates to the urinal, it is possible to maintain a positional relationship in which the line of sight is not easily matched with the adjacent user, and thus privacy between individuals can be protected. In addition, when a person who wants to urinate moves forward from the doorway toward the urinal, he / she can smoothly stand in front of the urinal without greatly changing the direction of the body in front of the urinal, and immediately start urination can do. Furthermore, when the user stands diagonally toward the wall in the toilet room, the user can advance and retreat with respect to the urinal without greatly detouring the user of the adjacent urinal. The traffic lines can be prevented from overlapping, and people in the toilet room can proceed smoothly even when crowded.

FIG. 1 shows a first premise technique of the present invention, and shows a urinal installed in a men's toilet.

A urinal 10 shown in FIG. 1 has a concave inner wall surface 12 where a urine hits a urinal body 11 that opens toward a user, and a drainage port 13 covered with an eye plate is provided at the lower part of the urinal body 11. Is provided. Further, the urinal 10 is asymmetrically formed so that the center in the width direction of the inner wall surface 12 of the toilet main body 11 is inclined in the front-rear direction with respect to the urination direction with respect to the conventional symmetric urinal, The inner wall surface 12 gradually increases in depth in the front-rear direction from one end in the width direction to the other end (from left to right).

  The inner wall surface 12 is formed so as to form a gentle concave curved surface from the left side to the right side in the urination direction, and the tangent L1 of the curved portion at the center in the width direction with respect to the center line C extending in the front-rear direction of the toilet body 11 Is inclined at an angle θ1 (acute angle side). The rightmost deepest portion of the inner wall surface 12 is a curved surface without a step and is continuous with the right wall surface 14 of the toilet body 11, and the urine urinated at the center of the urinal flows down to the vicinity of the deepest portion along the gentle concave surface, The urine splash reflected without being along the concave curved surface can be completely received by the right wall surface 14. The inclination angle θ1 is set to 55 ° to 75 ° (preferably 60 ° to 70 °).

  In the urinal 10 configured as described above, the tangent L of the inner wall surface 12 at the center in the width direction where the urine hits is not in a parallel positional relationship with a person who naturally stands in front of the urinal and urinates. Does not bounce off the inner wall surface 12 and flow down along the inner wall surface 12 without generating splashes.

According to the urinal, the inner wall surface 12 of the toilet body 11, asymmetrical as tangents L1 curved portion of the widthwise center forms a slope in the longitudinal direction toward the other end from the one widthwise side of the toilet bowl Thus, urination is repelled on the inner wall surface 12 and flows down along the inner wall surface 12 without generating splashes, and it is possible to prevent soiling of clothes and the floor surface due to scattering of urine outside the toilet. In this case, since the recoil of the urine can be prevented by the inclination of the inner wall surface 12, it is not necessary to urinate toward the target so as not to scatter the urine, or to intentionally divert the direction of urination to the side. Pissing can be performed naturally. In addition, since the shape of the toilet main body 11 with the inclined inner wall surface 12 prevents the urine from being scattered, the structure is as in the conventional example in which the toilet main body is moved up and down according to the physique of the user. There is an advantage that it does not become complicated and does not cause an increase in manufacturing cost or a failure.

Figure 2 shows a second base technology of the present invention are denoted by the same reference numerals in the first underlying technique and similar sections.

In the urinal 10 shown in the figure , the inner wall surface 15 has a smooth convex curved surface 15a and a concave curved surface 15b continuously from the left side to the right side in the urination direction, and the tangent L2 of the curved portion at the center in the width direction is. The toilet body 11 is inclined at an angle θ2 (acute angle side) with respect to the center line C extending in the front-rear direction. In this case, the inclination angle θ2 is smaller than the inclination angle θ1 of the first embodiment (θ2 <θ1), and is minimum near the center in the width direction of the inner wall surface 15. The inclination angle θ2 is set to 35 ° to 55 ° (preferably 40 ° to 50 °).

The rightmost deepest portion of the inner wall surface 15 is a curved surface having no step and is continuous with the right wall surface 14 of the toilet main body 11. The urine urinated in the center of the toilet main body 11 is near the deepest portion along the gentle concave curved surface 15b. The urine splashes that have flowed down and reflected without following the concave curved surface 15b are completely received by the wall surface 14 on the right side. In this case, forms a left convex surface 15a of the inner wall 15, the since the right side is formed so as to form a concave surface 15b convex curved surface 15a, the inclination angle θ2 of the widthwise central portion with respect to urination direction The inclination angle θ1 of the first prerequisite technology can be made smaller, and the urine bounced off the inner wall surface 15 can be rebounded less.

In the second premise technique , the tangent L2 of the curved portion at the center in the width direction of the inner wall surfaces 12 and 15 of the toilet main body 11 is set at predetermined angles θ1 and θ2 with respect to the center line C extending in the front-rear direction of the toilet main body 11. Although the inclination angle is set, when the center in the width direction of the inner wall surfaces 12 and 15 is a plane, the angles formed by the plane and the center line C may be set as the inclination angles θ1 and θ2.

  The inner wall surfaces 12 and 15 may be formed so that the degree of inclination changes in the height direction of the toilet body 11.

FIG. 3 shows a first embodiment of the present invention, and the same reference numerals are given to the same components as those in the base technology .

In the urinal 10 of the present embodiment, the toilet body 11 of the second prerequisite technology is formed such that the back surface 16 is inclined in the same direction as the inner wall surface 15, and the back surface 16 is a center line extending in the front-rear direction of the toilet body 11. An angle θ3 (acute angle side) is inclined with respect to C. That is, when the back surface 16 of the toilet body 11 is fixed to the wall surface A in the toilet room, when the user urinates to the urinal 10, it faces rightward so as to form an angle of (90 ° −θ 3) with respect to the wall surface A in the toilet room. Will stand in. When the back surface of the toilet main body 11 is not inclined like the toilet main body 11 of the second prerequisite technology , the dimension between the inner wall surface 15 and the rear surface in the direction where the depth of the inner wall surface 15 is shallow (left side in the figure). However, in this embodiment, since the back surface 16 is formed so as to be inclined in the same direction as the inner wall surface 15, the inner wall surface 15 and the back surface are formed in the direction where the depth of the inner wall surface 15 is shallow (left side in the figure). Therefore, the material cost of the urinal body 11 can be reduced and the weight can be reduced.

Incidentally, in the first embodiment, although the ones the user is tilted back 16 to stand in the right orientation with respect to the toilet room wall A, as shown in the second embodiment shown in FIG. 4 In addition, if the toilet main body 11 of the first embodiment is formed symmetrically with respect to the center line C, the user can be configured to stand to the left with respect to the wall surface A in the toilet room.

In the first and second embodiments, the toilet body 11 of the second premise technology is formed so that the back surface 16 is inclined. However, the toilet body 11 of the first premise technology is the same. It is also possible to form the back surface to be inclined.

FIG. 5 shows a third embodiment of the present invention, and shows a toilet provided with a plurality of urinals 10 of the first and second embodiments.

The toilet 20 of the present embodiment has an entrance 23 on the side of one wall 22 in the front-rear direction of the toilet room 21, and the wall surface of the wall 24 on the left side in the figure in the toilet room 21 has a plurality of small sizes of the second embodiment. The toilet bowls 10 are arranged in the front-rear direction, and a plurality of the urinals 10 of the third embodiment are arranged in the front-rear direction on the wall surface of the right wall 24 in the drawing in the toilet room 21. Thereby, each urinal 10 is installed diagonally so that the toilet body 11 faces the entrance / exit 23 side (lower side in the figure).

  As a result, any user who urinates stands with his / her back toward the entrance / exit 23, so that urination is not seen from a person outside the toilet 20 and privacy can be protected. Moreover, since the user who urinates with each urinal 10 stands diagonally with respect to the wall surface 24 in the toilet room 21, for example, the user who urinates with the urinal 10 on the left wall surface in the figure is always the user. Piss on the right side of the other user's back. Similarly, a user who urinates with the urinal 10 on the right wall surface in the drawing always urinates by looking at the back of another user who urinates on the left side of the user. Thereby, each user can protect each other's privacy, without matching each other's eyes | visual_axis.

  Furthermore, there are many opportunities for many people to urinate at the same time. For example, in a public large-scale toilet such as a highway service area or a concert hall, there will be a flow of traffic between those who will urinate and those who will quit urine. Overlap can cause congestion. On the other hand, according to this embodiment, since the toilet body 11 of the urinals 10 adjacent to each other is installed obliquely in the same left and right direction so as to face the entrance / exit 23 side, Compared to the case where the urinal is arranged so that the user faces the front, the person who is going to urinate from the entrance 23 moves toward the urinal 10 in front of the urinal 10. It is possible to smoothly stand in front of the urinal 10 without greatly changing the direction, and urination can be started promptly. In addition, since the user stands diagonally toward the wall in the toilet room, the user of the adjacent urinal 10 can move forward and backward with respect to the urinal 10 without greatly detouring. It is possible to prevent the movement lines (broken lines in the figure) of the retreating person from overlapping. Thereby, even in the time of congestion, the person in the toilet room 21 can advance smoothly.

In the third embodiment, the urinal 10 is installed on both the left and right wall surfaces 24 in the toilet room 21, but only a small wall surface 24 in the left and right direction in the toilet room 21 is small. The toilet 10 may be installed.

FIG. 6 shows a fourth embodiment of the present invention and shows a toilet provided with a plurality of urinals 10 of the first embodiment.

The toilet 30 of the present embodiment has an entrance 33 on each of the one wall 32 side and the other wall 32 side in the front-rear direction of the toilet room 31, and a plurality of wall surfaces of the wall 34 on the left side in the figure in the toilet room 31 The urinals 10 of the first embodiment are arranged in the front-rear direction, and a plurality of the urinals 10 of the first embodiment are arranged in the front-rear direction on the wall surface of the right side wall 34 in the drawing in the toilet room 31. . As a result, the urinal 10 on the wall surface side of the left wall 34 in the toilet room 31 is installed diagonally so that the toilet body 11 faces one of the doorways 33 (the lower side in the figure). The urinal 10 on the wall surface side of the right side wall 34 in the figure is installed obliquely so that the toilet body 11 faces the other doorway 33 side (upper side in the figure).

  Thereby, the user who entered from the one entrance 33 side (the lower side in the figure) proceeds toward the urinal 10 on the left side in the figure facing the user, and enters from the other entrance 33 side (the upper side in the figure). Since the user tries to move toward the urinal 10 on the right side in the drawing facing the user, the user's flow line (broken line in the drawing) entering / exiting from one entrance 33 and entering / exiting from the other entrance 33 The user's flow line (broken line in the figure) is separated, and the person in the toilet room 31 can be smoothly advanced.
