The right toilet seat mounting arm 22R has a notch 221R for attaching / detaching the hinge pin 60R (see FIG. 10). Since the pair of toilet seat mounting arms 22R and 22L extend to the rear of the seat surface portion 21, a space Q can be formed between them. The toilet seat mounting arms 22R and 22L are hinge pins 60R and the fixed shaft 34 of the toilet lid 30. The shaft support 12 of the casing 10 and the toilet lid mounting arms 32R and 32L are arranged in the space Q when mounted on the space Q. The right toilet seat mounting arm 22R is formed with a storage portion 25R that rotatably stores a part of the hinge portion 70, and the hammer-shaped tip portion 63R of the hinge pin 60R cannot be rotated on the outer surface side of the storage portion 25R. The hinge pin receiving body 80 to be held in is built in. The left toilet seat mounting arm 22L is formed with a storage portion 25L that rotatably stores the fixed shaft 34 of the toilet lid mounting arm 32L.

  Next, a structure for connecting the toilet seat 20 and the toilet lid 30 will be described. FIG. 10 is a view showing a connecting structure of the toilet seat and the toilet lid. The toilet seat 20 and the toilet lid 30 are attached to the hinge pins 60R and 60L in a state where the toilet seat attachment arms 22R and 22L and the toilet lid attachment arms 32R and 32L are connected by a seat lid connecting member, and are attached to and detached from the hinge pins 60R and 60L. Sometimes the toilet seat 20 and the toilet lid 30 are connected.

  Each of the pair of toilet lid mounting arms 32R and 32L is provided with a seat lid coupling member. For the left toilet lid mounting arm 32L, the above-described fixed shaft 34 corresponds to a seat lid connecting member. On the right toilet lid mounting arm 32R, a hinge portion 70 that is slidable to the left and right at the center of rotation corresponds to a seat lid connecting member. The hinge portion 70 is formed with a notch 73 for attaching / detaching the hinge pin 60R on the side surface of the annular body 71 having a through hole 72 into which the hinge pin 60R can be rotatably inserted, and two on the side surface of the annular body 71 near the shaft support portion. An extending portion 74 is formed. One extension portion 74 is formed with an operation projection 75 that is operated when the hinge portion 70 is slid. When the operating projection 75 is operated and the hinge portion 70 is slid to the shaft support portion side, the hinge portion 70 does not protrude from the side surface of the toilet seat mounting arm 32R and is not inserted into the toilet seat mounting arm 22R. Then, when it is slid to the opposite side (= toilet seat mounting arm 22R side) from the shaft support portion 12, a part of the hinge portion 70 protrudes from the side surface of the toilet seat mounting arm 32R on the toilet seat mounting arm side, and becomes the center of rotation of the toilet seat mounting arm 22R. Inserted. As described above, the fixed shaft 34 and a part of the hinge portion 70 are inserted into the rotation center portions of the left and right toilet seat mounting arms 22R and 22L, thereby connecting the toilet seat mounting arms 22R and 22L and the toilet lid mounting arms 32R and 32L. To do. Note that the fixed shaft 34 and the hinge portion 70 are rotatable with respect to the center of rotation of the toilet seat mounting arms 22R and 22L.

  Further, when the hinge portion 70 is slid to the shaft support portion side, the extension portion 74 protrudes from the side surface of the toilet lid mounting arm 32R on the shaft support portion side, and when the toilet lid 30 is to be mounted on the hinge pin 60R, the extension portion 74 is Cannot be mounted on the hinge pin 60R. On the other hand, when the hinge portion 70 is slid to the opposite side (= toilet seat mounting arm side) from the shaft support portion 12, the extending portion 74 does not protrude from the side surface of the toilet cover mounting arm 32R on the shaft support portion side. It becomes possible to attach to the hinge pin 60R. Note that the extended portion 74 may not protrude from the toilet lid mounting arm 32R even if the hinge portion 70 is slid to the shaft support portion side.

  Further, after the hinge part 70 is incorporated in the toilet lid mounting arm 32R, the retaining member 35 is attached to the toilet lid mounting arm 32R, and the operation protrusion is slid to the toilet seat mounting arm side to the maximum extent. 75 is engaged with a part of the toilet lid mounting arm 32R so that the hinge portion 70 does not come off from the left and right side surfaces of the toilet lid mounting arm 32R.

  Next, a structure in which the toilet seat 20 and the toilet lid 30 are attached to and detached from the casing 10 will be described. FIGS. 11-14 is a figure which shows a mode that the toilet seat 20 and the toilet lid 30 are removed from the casing 10 (hinge pin 60), and are mounted | worn again. 11 is a front view showing a state in which the toilet seat / toilet lid is removed from the casing, FIG. 12 is a perspective view showing a state in which the toilet seat / toilet lid is removed from the casing, and FIG. 13 shows a state in which the toilet seat / toilet lid is attached to the casing. FIG. 14 is a front view, and FIG. 14 is a perspective view showing a state in which the toilet seat / toilet lid is removed from the casing and placed on the toilet.

  The toilet seat 20 and the toilet lid 30 are connected and detached from the casing 10 (from the hinge pins 60R and 60L). As described above, the right toilet seat mounting arm 22R and the left toilet lid mounting arm 32L incorporate hinge pin receivers 80 and 90. A hinge pin receiver 80 provided on the right toilet seat mounting arm 22R includes a holding portion 81 that holds a hammer-shaped tip portion 63R of the hinge pin 60R in a non-rotatable manner, and a holding portion for removing the hinge pin 60R from the holding portion 81. An opening 82 formed by partially cutting 81 is provided. Immediately below the opening 82, a first holding body 28 that is attached to a shaft 26 protruding from the toilet seat mounting arm 22R in the axial direction of the hinge pin 60R via a coil spring 27 and is movable left and right is disposed. The first holding body 28 normally closes the opening 82 by the urging force of the coil spring 27, and holds the hinge pin 60R so as not to come off. The tip of the first holding body 28 is a guide part 281 having an arcuate cross section, and a part of the first holding body 28 is an operation part 282.

  The hinge pin receiver 90 provided on the left toilet lid mounting arm 32L is also for holding the hammer-shaped tip 63L of the hinge pin 60L in a non-rotatable manner inside, and for removing the hinge pin 60L from the holding portion 91. It has an opening 92 formed by partially cutting away the holding portion 91. Immediately below the opening 92, a second holding body 38 that is attached to a shaft 36 protruding from the toilet lid mounting arm 32L in the axial direction of the hinge pin 60L via a coil spring 37 and is movable to the left and right is disposed. The second holding body 38 normally closes the opening 92 by the urging force of the coil spring 37, and holds the hinge pin 60L so as not to come off. Further, the tip of the second holding body 38 is a guide portion 381 having an arcuate cross section.

  As described above, the toilet seat 20 and the toilet lid 30 can be attached to and detached from the hinge pins 60R and 60L only in a state where both are connected.

  When the toilet seat 20 and the toilet lid 30 are mounted, the hammer-shaped tip portions 63R and 63L of the hinge pins 60R and 60L are abutted against the arc surfaces of the guide portions 281 and 381 of the first holding body 28 and the second holding body 38. The toilet seat 20 and the toilet lid 30 are lowered directly. Then, the left and right guide portions 281 and 381 compress the coil springs 27 and 37 and open left and right, so that the opening portions 82 and 92 of the holding portions 81 and 91 of the hinge pin receivers 80 and 90 are exposed, and the holding portions 81 and 91 are exposed. The tip portions 63R and 63L of the hinge pins 60R and 60L are stored in the housing. After the hinge pins 60R and 60L are mounted, the first holding body 28 and the second holding body 38 are returned to their original positions by the urging force of the coil springs 27 and 37 to close the openings 82 and 92, thereby holding the hinge pins 60R and 60L. To do.

  When removing the toilet seat 20 and the toilet lid 30, opening the operation portion 282 of the first holding body 28 provided on the right toilet seat mounting arm 22 </ b> R with a finger in a direction in which the coil spring compresses opens the opening 82 of the holding portion 81. As a result, the right side of the toilet seat 20 and the toilet lid 30 is lifted to remove the hinge pin 60R from the holding portion 81 of the hinge pin receiver 80. Then, since the right side of the toilet seat 20 becomes a free end that is detached from the hinge pin 60R, the hinge pin 60L is also detached from the holding portion 91 of the toilet lid mounting arm 32L.

  In this manner, the toilet seat 20 and the toilet lid 30 can be attached to the casing 10 (hinge pins 60R, 60L) and removed.

  Next, a structure for preventing the toilet seat 20 from opening too much and a structure for preventing the hinge pins 60R and 60L from coming off will be described. FIG. 16 is a view showing a mechanism for preventing the toilet seat from being excessively opened by the hinge pin and a mechanism for preventing the hinge pin from coming off. In order to prevent the toilet seat 20 from opening too much, the casing 10 is usually provided with a stopper that restricts a part of the toilet seat 20 from abutting when the toilet seat 20 opens to a certain angle and opening beyond that angle. However, in the present embodiment, the entire top surface portion 11 of the casing 10 is an inclined surface, so that it is difficult to provide a stopper.

  Therefore, in the present embodiment, a stopper function is exhibited between the hinge pin 60 </ b> R and the casing 10 that are non-rotatably engaged with the toilet seat 20. As described above, the hinge pin 60R is provided with the protrusion 64 protruding in the circumferential direction in the middle of the cylindrical body 61. Bearing portions 121R and 121L that are integrally fixed to the casing 10 are provided on the side surface of the shaft support portion 12 of the casing 10 into which the base end portion 62R of the hinge pin 60R is inserted. The right bearing portion 121R has a wall portion 123 having a through-hole 122 into which the cylindrical body 61 and the protruding portion 64 of the hinge pin 60R can be inserted, and a protruding shape against which the protruding portion 64 abuts when the hinge pin 60R rotates to a predetermined angle. Two portions 124 are provided at positions that are point-symmetric. The hinge pin 60R causes the toilet seat opening / closing device 40 to hold the base end portion 62R by inserting the protruding portion 64 into the through hole 122 of the bearing portion 121R. The bearing portions 121R and 121L may be integrated with the casing 10.

  When the toilet seat 20 and the toilet lid 30 are attached to the hinge pin 60R and the toilet seat 20 and the toilet lid 30 are opened, the hinge pin 60R rotates accordingly. When the hinge pin 60R rotates, the protruding portion 64 rotates inside the bearing portion 121R and comes into contact with the protruding portion 124. Then, the hinge pin 60R does not rotate any more. That is, a mechanism for preventing the toilet seat 20 from opening too much is obtained. Further, the protruding portion 64 of the hinge pin 60R is obstructed by the wall portion 123 of the bearing portion 121R, thereby preventing the hinge pin 60R from coming off.

  In this way, the protruding portion 64 protruding in the circumferential direction of the hinge pin 60R serves as both a mechanism for preventing the toilet seat 20 from being excessively opened and a mechanism for preventing the hinge pin 60R from coming off.

  The left hinge pin 60L can be configured similarly. Further, a plurality of ribs that sandwich the outer periphery of the hinge pin 60L may be provided on the bearing portion 121L to make it difficult for the hinge pin 60L to come off.

  As described above, the toilet seat device according to the present embodiment includes the toilet lid mounting arms 32R and 32L on the inner side and the toilet seat mounting arms 22R and 22L with respect to the hinge pins 60R and 60L of the shaft support 12, as shown in FIG. It is attached to the outside position. For this reason, the side surface of the toilet seat 20 is always exposed to the side without being obstructed by the side surface of the toilet lid 30.

  Therefore, the side surface of the casing 10, the side surface of the toilet seat 20, and the side surface of the toilet lid 30 can be aligned on the same plane. Therefore, when wiping and cleaning the toilet seat device, the center of rotation of the side surface of the toilet seat is conventionally covered with the toilet lid, so that it was not possible to wipe all the corners unless removed from the hinge pins 60R and 60L. In the present embodiment, since the side surfaces of the toilet seat 20 and the toilet lid 30 are both exposed, it is possible to wipe even a fine part by quickly wiping the toilet seat 20 and the toilet lid 30 on the hinge pins 60R and 60L. As a result, good cleanability can be obtained.

  Moreover, since the toilet lid 30 does not cover the side surface of the toilet seat 20, the thinness of the toilet lid 30 is conspicuous, and a light impression can be given.

  Further, since the toilet seat mounting arm 22 is arranged outward from the toilet lid mounting arm 32, the seat surface portion 21 of the toilet seat 20 moves the region near the toilet seat mounting arm where the inclination is tight to the side end portion of the toilet seat, When the user sits on the toilet seat 20, the inclination near the toilet seat mounting arm 22 is less likely to hit the buttocks, and a better sitting comfort than before can be obtained.

  In the toilet seat device of the present embodiment, since the toilet lid mounting arms 32R and 32L are arranged inside the toilet seat mounting arms 22R and 22L, the toilet lid mounting arms 32R and 32L are located immediately after the seat surface portion 21 of the toilet seat 20. It will be. Since the toilet lid mounting arms 32R and 32L are positioned between the shaft support 12 of the casing 10 and the toilet seat mounting arms 22R and 22L, the buttocks of a person sitting on the toilet seat 20 between the shaft support 12 and the toilet seat mounting arms 22R and 22L. Walls 13 are formed on the left and right side surfaces of the shaft support portion 12 so as not to fall down. The walls 13 surround the front from below the hinge pins 60R and 60L. (See Figure 14)

  The wall body 13 is continuously formed on the side surface of the shaft support portion 12 and is provided so as to fill a gap between the toilet lid mounting arms 32R and 32L and the rear portion of the seat surface portion 21 of the toilet seat 20, and is closed. It has a hollow, substantially triangular cross-sectional shape that extends upward from the rear upper end of the 20 seating surface portions 21 and has an arc surface along the outer periphery of the toilet lid mounting arms 32R, 32L on the upper surface 131. In the state where the toilet seat 20 is closed, the upper end edge 132 of the wall 13 has only a slight gap between the toilet lid mounting arms 32R and 32L. Therefore, even if a person with a large physique sits on the toilet seat 20 and the buttocks reach the toilet lid mounting arms 32R and 32L, the buttocks are dropped into the gap between the toilet lid mounting arms 32R and 32L and the seat surface portion 21 of the toilet seat 20. There is nothing wrong.

  Further, the wall body 13 incorporates a toilet seat cord 29 for supplying power to the heater incorporated in the toilet seat 20. The toilet seat cord 29 is taken out from an opening 133 provided on the outer surface of the wall 13 and connected to a heater in the toilet seat. The toilet seat 20 has a storage portion (not shown) for storing a part of the toilet seat cord 29 so that it can be pulled out. When the toilet seat 20 and the toilet lid 30 are removed from the casing 10, the toilet seat cord 29 is moved accordingly. The toilet seat 20 can be moved by being pulled out. Also in this case, the opening 133 through which the toilet seat cord 29 is drawn out is located on the outer surface of the wall 13 that is located adjacent to the toilet seat mounting arms 22R and 22L beyond the toilet lid mounting arm 32L. There will be no scratches on the surface of the cord.

  As described above, according to the toilet seat device of the present embodiment, since the entire outer side surface of the toilet seat is exposed outside the toilet seat device, the entire side surface of the toilet seat can be wiped without separating the toilet seat and the toilet lid. It can be carried out.

  Further, if the toilet seat / toilet lid is lifted while operating only the right side operation part, the toilet seat / toilet lid can be removed from the hinge pin, so that the toilet seat / toilet lid can be attached and detached more easily.

  In addition, a wall that fills the gap between the toilet lid mounting arm and the rear end of the toilet seat is provided inside the toilet seat mounting arm, so that the buttock of the person sitting on the toilet seat does not fall into the clearance, and the comfort Can keep.

  As a method for heating the toilet seat, the heater built in the seat surface portion 21 is used in the present embodiment, but a hot air may be circulated in the toilet seat from a hot air generation source built in the casing 10.
