Description

  The present invention relates to a toilet seat support structure that rotatably supports a toilet seat with respect to a casing.

  The toilet seat support structure is a structure in which the toilet seat is rotatably supported with respect to a casing provided on the upper surface of the rear portion of the toilet bowl so that the toilet seat is raised or tilted with respect to the toilet bowl according to the purpose of use of the user. . Some toilet seats are provided with a heating device. The heating device is a heater or the like that is heated by supplied electric power, and a supply source that supplies electric power to the heating device provided inside the casing and the heating device are connected by a harness. The harness is passed through the toilet seat from the toilet seat through the toilet seat support structure. As a toilet seat support structure through which a harness can pass, there is, for example, a structure in which a hinge pipe inserted into the toilet seat and the casing is supported by a support portion formed inside the casing (see FIG. 4 of Patent Document 1).

  Here, since the dimensional accuracy of the toilet bowl is lower than that of the toilet seat, there is a possibility that a gap may be formed between a part of the contact portion with the toilet bowl formed on the tilted toilet seat and the toilet bowl. If the toilet seat support structure is a structure that restricts the downward movement of the hinge pipe, when the user is seated on the tilted toilet seat and the vertical load is applied to the toilet seat, the toilet seat eliminates the gap between the toilet seat and the toilet seat. As a result, the durability of the toilet seat support structure may be reduced. Therefore, there is a toilet seat support structure including an elastic member that elastically supports the hinge pipe inserted into the casing from below in order to suppress deformation of the toilet seat.

Next, the elastic member 3 is elastically deformed and elastically deformed so that the claw portion 34 can face the insertion region S1 in the axial direction of the elastic member 3 in the normal state. For example, the worker holds the collar portion 36 and twists the elastic member 3 so that the claw portion 34 moves from the locking region S2 side to the insertion region S1 side. Since the insertion region S1 where the claw portion 34 opposes in the axial direction is wider than the claw portion 34, the claw portion 34 is inserted into the elastic member locking hole 127a by moving the elastic member 3 toward the side surface 123a in the axial direction. While inserting into the region S1, the elastic support portion 31 is further inserted into the elastic support portion insertion hole 126a. The nail | claw part 34 is inserted in insertion area S1 until it exposes to the opening part 127e (refer FIG. 10). At this time, the nail | claw part 34 is a state which is not facing the elastic member locking surface 127b in the axial direction. When the elastic member 3 is shifted from the elastically deformed state to the normal state, the elastic member 3 is elastically restored, and the claw portion 34 moves from the insertion region S1 to the locking region S2. At this time, the moving claw portion 34 may come into contact with the stepped portion 127d. However, since the stepped portion 127d is formed with an inclined surface, the claw portion 34 can be smoothly guided to the locking region S2. Therefore, it can suppress that the movement of the nail | claw part 34 is inhibited. When the elastic member 3 is in the normal state, the claw portion 34 is positioned in the locking region S2 in the axial direction, and faces the elastic member locking surface 127b in the axial direction.

  As described above, in the toilet seat support structure 1 according to the present embodiment, as shown in FIG. 9, the elastic support portion 31 inserted into the elastic support portion insertion hole 126a is inserted into the contact surface 126b and the casing side insertion hole 125a. The supporting surface 31d is in contact with the hinge pipe 2 and the pair of elastic support pieces 31b and 31c are in contact with the contact surface 126b. Elastic support from below. Accordingly, when a vertically downward load is applied to the tilted toilet seat 110, the elastic support portion 31 is elastically deformed vertically downward, and the hinge pipe 2 moves vertically downward with respect to the casing side insertion hole 125a. The deformation of the toilet seat 110 can be suppressed, and the durability of the toilet seat support structure 1 can be improved.

  Further, in the toilet seat support structure 1 according to the present embodiment, as shown in FIG. 10, the claw portion 34 inserted into the elastic member locking portion 127 has the elastic member locking in the axial direction in the normal state of the elastic member 3. Opposite the surface 127b. Therefore, when the elastic member 3 attempts to move toward the inside of the casing 120 in the axial direction, the claw portion 34 contacts the elastic member locking surface 127b, and the elastic member 3 moves toward the inside of the casing 120 in the axial direction with respect to the casing 120. The movement is restricted, and the elastic member 3 is locked in the axial direction by the elastic member locking portion 127. Here, when the elastic member 3 is in a normal state, the claw portion 34 is located in the locking region S2 and does not move to the insertion region S1, as shown in FIG. Accordingly, the claw portion 34 inserted into the elastic member locking portion 127 does not come out of the elastic member locking portion 127 unless the elastic member 3 is elastically deformed until the claw portion 34 is positioned in the insertion region S1. Therefore, the elastic member 3 can be fixed inside the casing 120. As a result, the elastic member 3 itself is locked in the axial direction by the elastic member locking portion 127, so that a member for fixing the elastic member 3 inside the casing 120 is not required, and the elastic member 3 can be simplified. It can be fixed inside the casing 120 with a simple configuration. Thereby, the number of parts of the toilet bowl upper surface facility 100 can be reduced, and the manufacturing cost can be reduced. Moreover, since the process which fixes the elastic member 3 inside the casing 120 is not given, the design freedom inside the casing 120 can be improved.

  Further, as shown in FIG. 9, the toilet seat support structure 1 according to the present embodiment has a hinge in which the pipe contact portion 35 of the elastic member 3 locked by the elastic member locking portion 127 is inserted into the casing side insertion hole 125a. It faces the other end 2b of the pipe 2 in the axial direction. Therefore, when the hinge pipe 2 tries to move to the inside of the casing 120 in the axial direction, the other end 2b of the hinge pipe 2 comes into contact with the pipe contact portion 35 as shown in FIG. Therefore, the elastic member 3 regulates the movement toward the inside of the casing 120 in the axial direction. Therefore, the hinge pipe 2 can be prevented from falling off the toilet seat side insertion portion 114 and the casing side insertion portion 125. Moreover, the pipe contact part 35 can move to the inside of the casing 120 in the axial direction when the first connecting part 32 and the second connecting part 33 are elastically deformed. Accordingly, the pipe contact portion 35 can elastically support the hinge pipe 2 in the direction from the inner side of the casing 120 toward the side surface 123a in the axial direction.

  In addition, although this embodiment demonstrated the case where the casing 120 was a toilet seat box, this invention is not limited to this, and when a low tank is installed in the rear upper surface of the western style toilet bowl 200, a low tank is covered. The low tank cover may be a casing.

  As described above, the toilet seat support structure according to the present invention is useful for a toilet seat support structure that supports the toilet seat in a rotatable manner with respect to the casing, and is suitable for fixing the elastic member to the inside of the casing with a simple configuration. Yes.
