Summary of the Invention

Problems to be Solved by the Invention

[0004] In the toilet installation system described in Patent Document 1, a drain socket is fixed to the floor so as to communicate with a drain pipe installed in the floor of the toilet room, and the toilet is fixed to the floor via the drain socket by screwing an adjustment member (bolt) through a hole in the toilet bowl into this drain socket. However, in this toilet installation system, the installation position of the toilet bowl relative to the floor is determined by the position of the drain pipe installed in the floor, and the installation position of the toilet bowl cannot be adjusted. For this reason, in the toilet installation system described in Patent Document 1, it is difficult to install the toilet bowl so that, for example, the rear end of the toilet bowl is in contact with the wall of the toilet room.

[0005] Therefore, the present invention aims to provide a flush toilet in which the installation position of the flush toilet body can be adjusted. [Means for solving the problem]

[0006] To solve the above-mentioned problems, the present invention provides a flush toilet that connects to a drain socket fixed to the floor surface by sliding on the floor surface, comprising: a flush toilet body having a bowl portion for receiving waste, a drain trap pipe extending from the lower part of the bowl portion, and a connecting pipe communicating with the downstream side of the drain trap pipe and protruding toward the rear; a drain socket having a drain pipe connection portion connected to a drain pipe provided on the floor surface, and a toilet body connection portion opening toward the front to connect to the connecting pipe of the flush toilet body; and a fixing block for fixing a toilet fixing screw that extends through the side wall surface of the flush toilet body, wherein the fixing block is fixed to the floor surface with a block fixing screw by fastening together with a first flange portion provided on the drain socket.

[0007] With the present invention configured in this way, the flush toilet body is equipped with a connecting pipe that protrudes toward the rear, and the drain socket is equipped with a toilet body connection part that opens toward the front. Therefore, the installation position of the flush toilet body can be adjusted by connecting the connecting pipe and the toilet body connection part. Furthermore, a fixing block for fixing the toilet fixing screw that extends through the side wall surface of the flush toilet body is fixed to the floor surface with a block fixing screw by fastening together with a first flange part provided on the drain socket. Therefore, no additional floor area is required to fix the fixing block to the floor surface, and the present invention can be applied to flush toilet bodies with a narrow base width.

[0008] In the present invention, preferably, the fixing block and the first flange portion of the drain socket, which are fastened together, are configured to be adjustable in relative position in the front-to-back direction of the toilet body.

[0009] According to the present invention configured in this way, the fixing block and the first flange portion of the drain socket, which are fastened together, are configured to be able to adjust their relative position in the front-to-back direction of the toilet body. Therefore, even if the position of the toilet body changes due to adjustment of the installation position, the fixing block can be positioned so that the toilet fixing screws extending through the side wall surface of the toilet body are securely fixed to the fixing block.

[0010] In the present invention, preferably, the fixing block is fixed to the floor surface behind the toilet bowl body connection portion of the drain socket.

[0011] According to the present invention configured in this way, since the fixing block is fixed to the floor surface behind the toilet bowl connection portion of the drain socket, a force that pulls the fixing block away from the floor surface is less likely to act on the fixing block based on the force applied to the drain socket when connecting the connecting pipe of the flush toilet bowl to the toilet bowl connection portion, thereby suppressing displacement of the fixing block.

[0012] In the present invention, preferably, the drain socket has a second flange portion for fixing the drain socket to the floor surface on the side of the drain pipe, in addition to a first flange portion that is fastened together with the fixing block.

[0013] According to the present invention configured in this way, in addition to the first flange portion that is fastened together with the fixing block, the drain socket is provided with a second flange portion for fixing the drain socket to the floor surface on the side of the drain pipe, so that the drain socket can be reliably connected to the drain pipe.

[0014] In the present invention, preferably, the width of the second flange portion of the drain socket is greater than the width of the first flange portion.

[0015] According to the present invention configured in this way, since the width of the second flange portion of the drain socket is larger than the width of the first flange portion, the drain socket can be more firmly fixed to the floor surface near the drain pipe, and the connection between the drain socket and the drain pipe can be made reliable.

[0016] In the present invention, preferably, the first flange portion of the drain socket is provided with an elongated hole in the front-to-back direction through which a block fixing screw for fastening together with the fixing block passes, and the range in the front-to-back direction in which this elongated hole is provided is longer than the front-to-back length of the fixing block.

[0017] With the present invention configured in this way, the range in which the elongated holes provided in the first flange portion for passing the block fixing screws, which are fastened together with the fixing block, are provided is longer than the length of the fixing block, so that the fixing position of the fixing block can be adjusted over a sufficiently wide range.

[0018] In the present invention, preferably, the first flange portion of the drain socket is configured to be thinner in the portion that contacts the fixing block to which it is fastened together, compared to other portions.

[0019] According to the present invention configured as described above, since the portion of the first flange portion that abuts against the fixed block is configured to be thinner than other portions, the influence of the force applied from the outside to the fixed block hardly reaches the entire first flange portion, and it is possible to suppress the displacement of the fixed position of the drain socket due to the external force acting on the fixed block.

Effect of the Invention

[0020] According to the flush toilet of the present invention, the installation position of the flush toilet body can be adjusted.

Mode for Carrying Out the Invention

[0022] Next, a flush toilet according to an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a flush toilet according to an embodiment of the present invention. FIG. 2 is a side sectional view of a flush toilet according to an embodiment of the present invention. FIG. 3 is a perspective view of a flush toilet according to an embodiment of the present invention as viewed from the back.

[0023] As shown in Figures 1 to 3, the flush toilet 1 according to an embodiment of the present invention comprises a flush toilet body 2 having a bowl portion 2a and a drain trap pipe 2b, a drain socket 4 connecting a drain pipe provided on the floor surface to the drain trap pipe 2b, and a fixing block 6. The flush toilet 1 of this embodiment is configured to discharge flushing water and waste to a drain pipe D provided on the floor surface F via the drain socket 4. Furthermore, as shown in Figure 3, in this embodiment, the flush toilet body 2 is configured to be fixed to the floor surface F by fixing toilet fixing screws 8 to the fixing block 6 through through holes 2g provided on both side wall surfaces 2c.

[0024] As shown in Figure 2, the flush toilet body 2 comprises a bowl portion 2a for receiving waste, a drain trap pipe 2b extending from the lower part of the bowl portion 2a, and a connecting pipe 2d that communicates with the downstream side of the drain trap pipe 2b and protrudes toward the rear. Furthermore, a rim outlet 2e from which flushing water is discharged is provided at the upper end of the bowl portion 2a. In addition, in this embodiment, the toilet body 2 is a full-skirt type toilet whose sides are covered by side wall surfaces 2c.

[0025] During toilet flushing, flushing water is discharged from the rim outlet 2e through a water channel provided inside the toilet bowl body 2. The flushing water discharged from the rim outlet 2e flows down while swirling inside the bowl 2a, cleaning the waste receiving surface of the bowl 2a, and is then discharged into the drain pipe D via the drain socket 4.

[0026] Although the flush toilet 1 in this embodiment is a wash-down type flush toilet without a jet nozzle, the present invention can be applied to any type of flush toilet, such as a siphon jet type flush toilet equipped with a jet nozzle.

[0027] The drain trap pipe 2b is a pipe that extends from the bottom of the bowl section 2a toward the rear of the toilet body 2. The drain trap pipe 2b is composed of a riser pipe that extends diagonally upward from the bottom of the bowl section 2a and a connecting pipe 2f that communicates with the downstream end of the riser pipe and protrudes toward the rear. The height of the top of this riser pipe determines the water level of the water in the bowl section 2a. The water in the bowl section 2a seals the drain trap pipe 2b. The connecting pipe 2d of the drain trap pipe 2b is a circular pipe that protrudes almost horizontally toward the rear of the toilet body 2 and is connected to the drain socket 4.

[0028] Next, the structure of the drain socket 4 will be described with reference to Figures 4 and 5. Figure 4 is a perspective view of a drain socket 4 provided in a flush toilet according to an embodiment of the present invention. Figure 5 is a side cross-sectional view of a drain socket 4 provided in a flush toilet according to an embodiment of the present invention.

[0029] As shown in Figures 4 and 5, the drain socket 4 comprises a drain pipe connection part 4a connected to a drain pipe D provided on the floor surface F, and a toilet body connection part 4b that opens forward to connect to the connecting pipe 2d of the flush toilet body 2. That is, as shown in Figure 5, the drain socket 4 is composed of a pipe section 4c formed in a roughly U shape, which is configured to connect the drain pipe connection part 4a that opens downward and the toilet body connection part 4b that opens forward.

[0030] The drain pipe connection part 4a is a circular opening that opens downwards, and the drain socket 4 is fixed to the floor surface F of the toilet room so that the drain pipe connection part 4a is received into the drain pipe D provided on the floor surface F.

[0031] The toilet body connection section 4b is a circular opening that faces forward and is configured to receive the connecting pipe 2d of the flush toilet body 2 from the front. Specifically, an annular packing 10 is attached to the toilet body connection section 4b, and by inserting the connecting pipe 2d horizontally into this packing 10 from the front, the flush toilet body 2 and the drain socket 4 can be connected in a watertight manner. The amount of insertion of the connecting pipe 2d into the packing 10 is adjustable within a predetermined range, and by changing the amount of insertion of the connecting pipe 2d, the front-to-back position of the flush toilet body 2 relative to the drain socket 4 can be adjusted.

[0032] The conduit section 4c is a pipe that is roughly U-shaped overall, formed from a first horizontal conduit extending roughly horizontally backward from the toilet body connection section 4b, a vertical conduit extending downward from the downstream end of the first horizontal conduit, and a second horizontal conduit extending roughly horizontally forward from the lower end of the vertical conduit. In this embodiment, the drain pipe connection section 4a of the drain socket 4 is configured to be located further forward of the toilet body 2 than the toilet body connection section 4b. That is, the connecting pipe 2d of the toilet body 2 is connected to the drain socket 4 on the rearward side of the drain pipe D.

[0033] Next, as shown in Figure 4, a first flange portion 12 is provided at the rear of the drain socket 4 so as to protrude on both sides in the width direction. This first flange portion 12 is a roughly rectangular plate-shaped portion formed to protrude on both sides in the width direction from the lower end of the vertical pipe of the pipe section 4c. That is, when the drain socket 4 is attached to the floor surface F, the lower surface of the first flange portion 12 abuts against the floor surface F.

[0034] Furthermore, two elongated holes 12a are provided on each side of the first flange portion 12, extending in the front-to-back direction (only one side is shown in Figure 4). The drain socket 4 is attached to the floor surface F by fixing block fixing screws 14 to the floor surface F through the elongated holes 12a of the fixing block 6 and the first flange portion 12. That is, the fixing block 6 is fixed to the floor surface F with block fixing screws 14 by fastening it together with the first flange portion 12 provided on the drain socket 4. Thus, each elongated hole 12a is a hole through which block fixing screws 14 pass for fastening the first flange portion together with the fixing block 6.

[0035] Furthermore, the portion of the first flange 12 that contacts the fixing block 6 is made thinner than the other portions of the first flange 12. By making the portion that contacts the fixing block 6 thinner than the other portions, when an external force acts on the fixing block 6, the force transmitted to the drain socket 4 via the fixing block 6 can be blocked at the portion of the first flange 12. As a result, when an external force acts on the fixing block 6, the main body portion of the drain socket 4 (the portion other than the first flange 12) is deformed as a result, and the risk of a decrease in watertightness between the drain socket 4 and the toilet body 2, and between the drain socket 4 and the drain piping D, can be reduced.

[0036] On the other hand, a second flange portion 16 is provided at the front of the drain socket 4, separate from the first flange portion 12. This second flange portion 16 is a substantially circular plate-shaped portion formed to surround the drain pipe connection portion 4a of the drain socket 4, and the second flange portion 16 allows the drain socket 4 to be fixed to the floor surface F on the side of the drain pipe D. That is, when the drain socket 4 is attached to the floor surface F, the lower surface of the second flange portion 16 abuts against the floor surface F. In addition, in the width direction of the toilet body 2, the second flange portion 16 is larger than the first flange portion 12. That is, as shown in Figure 4, the width W2 of the second flange portion 16 of the drain socket 4 is larger than the width W1 of the first flange portion 12. Therefore, the drain socket 4 can be fixed more firmly to the floor surface F near the drain pipe D, and the connection between the drain socket 4 and the drain pipe D can be made secure.

[0037] Furthermore, arc-shaped holes 16a extending in the front-to-back direction of the toilet bowl body 2 are provided on both sides of the second flange portion 16. These two holes 16a are located to the side of the drain pipe D, and by passing socket fixing screws 18 through each hole 16a and fixing them to the floor surface F, the drain socket 4 can be fixed to the floor surface F to the side of the drain pipe D. This allows the drain pipe connection portion 4a of the drain socket 4 to be firmly and securely connected to the drain pipe D. In addition, each hole 16a is formed as an elongated hole in a substantially arc shape centered on the center point of the circular cross-section drain pipe connection portion 4a.

[0038] Next, the fixing block 6 is a roughly rectangular parallelepiped member that is elongated in the front-to-back direction of the toilet bowl body 2, and in this embodiment, it is made of resin. In addition, protrusions 6a are formed at the lower end of the fixing block 6, each protruding in the front-to-back direction. Each of these protrusions 6a has a through hole 6b that penetrates vertically for passing the block fixing screw 14 through. When fixing the drain socket 4 to the floor surface F, the bottom surface of the fixing block 6 is brought into contact with the upper surface of the first flange portion 12, and in this state, the block fixing screw 14 is fixed to the floor surface F through each through hole 6b and each elongated hole 12a. That is, the fixing block 6 is fixed to the floor surface F with the block fixing screw 14 by fastening together with the first flange portion 12 of the drain socket 4.

[0039] Furthermore, the range R in the front-to-back direction where two elongated holes 12a are formed in the first flange portion 12, is longer than the front-to-back length of the fixing block 6. Therefore, the relative positions of the fixing block 6 and the first flange portion 12 of the drain socket 4 can be adjusted in the front-to-back direction of the toilet body 2. Preferably, taking into account variations during construction and variations in ceramics, the range R is set to be 20 mm or more, more preferably 30 mm or more, longer than the front-to-back length of the fixing block 6. Also, as shown in Figures 2 and 4, the fixing block 6 is fixed to the floor surface F behind the toilet body connection portion 4b of the drain socket 4. After the toilet body 2 is positioned, the toilet fixing screws 8 are inserted through the through holes 2g provided in the side wall surfaces 2c on both sides of the toilet body 2, and the tips of each toilet fixing screw 8 are screwed into the side surface of the fixing block 6 to fix it. In this embodiment, each toilet fixing screw 8 is a self-tapping screw, and by rotating it while pressing its tip against the side of the fixing block 6, the toilet fixing screw 8 is screwed into the fixing block 6 while forming threads.

[0040] Next, the procedure for installing a flush toilet 1 according to an embodiment of the present invention in a toilet room will be described. First, as shown in Figure 5, the drain socket 4 is positioned on the floor surface F of the toilet room so that the drain pipe connection part 4a is inserted into the drain pipe D provided on the floor surface F. In this state, the drain socket 4 is fixed to the floor surface F by screwing two socket fixing screws 18 into the floor surface F through the arc-shaped hole 16a (Figure 4) formed in the second flange portion 16 of the drain socket 4.

[0041] Each hole 16a is formed in an arc shape centered on the center point of the drain pipe connection portion 4a of the drain socket 4. Therefore, with the socket fixing screws 18 temporarily fastened, the installation direction of the drain socket 4 can be finely adjusted while maintaining the alignment of the center of the drain pipe connection portion 4a with the center of the drain pipe D. After accurately adjusting the installation direction of the drain socket 4, the socket fixing screws 18 are tightened to fix the drain socket 4 to the floor surface F.

[0042] Next, the fixing block 6 is fastened together with the first flange portion 12 of the drain socket 4 and fixed to the floor surface F. First, the fixing block 6 is placed on each of the first flange portions 12 on both sides of the drain socket 4. Here, the front-to-back position of the fixing block 6 should be adjusted so that, with the toilet body 2 in the predetermined position, the tip of the toilet fixing screw 8 inserted through the through hole 2g (Figure 3) of the toilet body 2 reaches near the front-to-back center of the fixing block 6. For example, as shown in Figure 2, when the toilet body 2 is positioned so that its rear end abuts against the wall surface W of the toilet room, the fixing block 6 is positioned so that the distance from the wall surface W to the front-to-back center of the fixing block 6 is a predetermined distance D1. This predetermined distance D1 is the horizontal distance from the rear end of the toilet body 2 to the through hole 2g, and is a distance given in advance as part of the specifications of the toilet 1.

[0043] Here, the first flange portion 12 of the drain socket 4 is provided with an elongated hole 12a to allow the block fixing screw 14 (Figure 4) that secures the fixing block 6 to pass through. Therefore, the relative position of the fixing block 6 and the first flange portion 12 of the drain socket 4 can be appropriately adjusted in the front-to-back direction of the toilet body 2. As a result, even if there is an error in the distance of the drain pipe D installed on the floor surface F from the wall surface W, the fixing block 6 can be fixed in the correct position. As a result, the toilet fixing screw 8 that extends through the side wall surface 2c of the toilet body 2 can be securely fixed to the fixing block 6.

[0044] After positioning the fixing blocks 6 at the appropriate locations on both sides of the drain socket 4, the block fixing screws 14 are fixed to the floor surface F through the through holes 6b of the fixing blocks 6 and the elongated holes 12a of the first flange portion 12. In this way, each fixing block 6 is fixed to the floor surface F by the block fixing screws, together with the first flange portion 12 provided on the drain socket 4. Here, since each fixing block 6 is fastened together with the drain socket 4, the floor surface F is not occupied by each fixing block 6, and the narrow space inside the toilet body 2 can be used effectively compared to when each fixing block 6 is fixed to the floor surface F separately from the drain socket 4.

[0045] After fixing the drain socket 4 to the floor surface F in this manner, the flush toilet body 2 is placed in front of the drain socket 4, and the flush toilet body 2 is slid toward the drain socket 4 on the floor surface F. In the example shown in Figure 2, after placing the flush toilet body 2 in front of the drain socket 4, the flush toilet body 2 is slid toward the wall surface W. As a result, the connecting pipe 2d protruding toward the rear of the flush toilet body 2 is inserted into the toilet body connection part 4b which opens toward the front of the drain socket 4, and the flush toilet body 2 and the drain socket 4 are connected.

[0046] As described above, the flush toilet 1 of this embodiment is a "slip-in" type flush toilet that can be connected to a drain socket 4 fixed to the floor surface F by sliding the flush toilet body 2 on the floor surface F. Here, as described above, the insertion amount of the connecting pipe 2d of the flush toilet body 2 into the toilet body connection part 4b of the drain socket 4 can be adjusted within a predetermined range. That is, the installation position of the flush toilet body 2 can be adjusted by connecting the connecting pipe 2d and the toilet body connection part 4b. Therefore, even if there is an error in the distance from the wall surface W on which the drain pipe D is installed, or if there is a manufacturing error in the dimensions of the flush toilet body 2, the flush toilet body 2 can be positioned so that the rear end of the flush toilet body 2 is in close contact with the wall surface W.

[0047] Furthermore, when inserting the connecting pipe 2d of the flush toilet body 2 into the toilet body connection part 4b of the drain socket 4, a force acts on the toilet body connection part 4b pushing it backward. However, since the fixing block 6 is fixed to the floor surface F behind the toilet body connection part 4b of the drain socket 4, a force that pulls the fixing block 6 away from the floor surface F is less likely to act, and displacement of the fixing block 6 can be suppressed. In addition, the drain socket 4 is provided with a second flange part 16 that fixes the drain socket 4 to the floor surface F on the side of the drain pipe D, so even if a force acts on the toilet body connection part 4b pushing it backward, the connection of the drain socket 4 to the drain pipe D can be made secure.

[0048] After positioning the flush toilet body 2 in the correct location, the toilet fixing screws 8 are inserted through the through holes 2g formed in the side walls 2c on both sides of the flush toilet body 2, and the toilet fixing screws 8 are rotated while being pushed in with a screwdriver (not shown). This causes the tips of the toilet fixing screws 8 to be screwed into the side of the fixing block 6, and the toilet fixing screws 8 are fixed to the fixing block 6. In this way, the flush toilet body 2 is fixed to the floor surface F of the toilet room, and the installation of the flush toilet 1 is completed.

[0049] In the flush toilet 1 embodiment of the present invention, the flush toilet body 2 is equipped with a connecting pipe 2d that protrudes toward the rear, and the drain socket 4 is equipped with a toilet body connection part 4b that opens toward the front. Therefore, the installation position of the flush toilet body 2 can be adjusted by connecting the connecting pipe 2d and the toilet body connection part 4b. Furthermore, a fixing block 6 for fixing a toilet fixing screw 8 that extends through the side wall surface 2c of the flush toilet body 2 is fixed to the floor surface F with a block fixing screw 14 by fastening together with a first flange part 12 provided on the drain socket 4. Therefore, no additional floor area is required to fix the fixing block 6 to the floor surface F, and the present invention can be applied to flush toilet bodies 2 with a narrow base width.

[0050] Furthermore, in the flush toilet 1 of this embodiment, the fixing block 6 and the first flange portion 12 of the drain socket 4, which are fastened together, are configured to be able to adjust their relative positions in the front-rear direction of the flush toilet body 2. Therefore, even if the position of the flush toilet body 2 changes due to adjustment of the installation position, the fixing block 6 can be positioned so that the toilet fixing screws 8 that extend through the side wall surface 2c of the flush toilet body 2 are securely fixed to the fixing block 6.

[0051] Furthermore, according to the flush toilet 1 of this embodiment, since the fixing block 6 is fixed to the floor surface F behind the toilet body connection part 4b of the drain socket 4, a force that pulls the fixing block 6 away from the floor surface F is less likely to act on the fixing block 6 based on the force applied to the drain socket 4 when the connecting pipe 2f of the flush toilet body 2 is connected to the toilet body connection part 4b, and displacement of the fixing block 6 can be suppressed.

[0052] Furthermore, according to the flush toilet 1 of this embodiment, in addition to the first flange portion 12 which is fastened together with the fixing block 6, the drain socket 4 is equipped with a second flange portion 16 for fixing the drain socket 4 to the floor surface F on the side of the drain pipe D, so that the drain socket 4 can be reliably connected to the drain pipe D.

[0053] Furthermore, according to the flush toilet 1 of this embodiment, the width W2 of the second flange portion 16 of the drain socket 4 is larger than the width W1 of the first flange portion 12, so that the drain socket 4 can be more firmly fixed to the floor surface F near the drain pipe D, and the connection between the drain socket 4 and the drain pipe D can be made reliable.

[0054] Furthermore, according to the flush toilet 1 of this embodiment, the range R provided in the first flange portion 12 through which the block fixing screw 14, which is fastened together with the fixing block 6, passes is longer than the length of the fixing block 6, so the fixing position of the fixing block 6 can be adjusted over a sufficiently wide range.

[0055] Furthermore, according to the flush toilet 1 of this embodiment, the portion of the first flange 12 that contacts the fixing block 6 is made thinner than other portions, so that the influence of external forces applied to the fixing block 6 does not easily extend to the entire first flange 12, and it is possible to suppress the shifting of the fixing position of the drain socket 4 due to external forces acting on the fixing block 6.

[0056] Although embodiments of the present invention have been described above, various modifications can be made to the embodiments described above. [Explanation of Symbols]
