Specifically, the receiving portion 38 is provided so as to protrude from the base portion 28 to the second functional component 24 side (upper side in the drawing) in the Z direction. At least three receiving portions 38 are provided on the base portion 28.

  The support member 36 includes a plurality of fixed portions 42 that are integrated with the plurality of second functional components 24. The fixed portion 42 is a portion that is fixed to the receiving portion 38 so as to be relatively movable. The term “integrated” in this specification means that the two elements referred to can be moved together, regardless of whether the two elements are part of the same member. . Although the fixed part 42 of this embodiment shows the example provided in the support member 36 separate from the 2nd functional component 24, it is that it may be provided in the 2nd functional component 24. FIG.

  The fixed portion 42 has a plate shape with the Z direction as the thickness direction. The fixed portion 42 is provided individually corresponding to each receiving portion 38. The fixed portion 42 of the present embodiment is provided so as to protrude laterally from a plurality of side portions of the support member 36 when viewed from the Z direction (see FIG. 4).

  The pressing member 44 is connected to the receiving portion 38 in a state where the impact absorbing members 46 and 48 and the fixed portion 42 are pressed from the side opposite to the receiving portion 38. The pressing member 44 of this embodiment is a screw member. The pressing member 44 includes a shaft portion 44 a that passes through a through hole 42 a formed in the fixed portion 42, and a head portion 44 b that presses the fixed portion 42 from the side opposite to the receiving portion 38. In the present embodiment, the shaft portion 44a is formed with a male screw portion, and the receiving portion 38 is formed with a female screw hole. The holding member 44 of the present embodiment is connected to the receiving portion 38 so as not to move relative thereto by screwing the male screw portion of the shaft portion 44 a into the female screw hole of the receiving portion 38. The head 44b is provided at the end of the shaft portion 44a opposite to the fixed portion 42. Hereinafter, the radial direction of a circle centered on the central axis of the shaft portion 44a is also simply referred to as “radial direction”.

  FIG. 6 is a view as seen from an arrow D in FIG. As shown in FIGS. 5 and 6, the shock absorbing members 46 and 48 include a first shock absorbing member 46 provided between the pressing member 44 and the fixed portion 42, and between the fixed portion 42 and the receiving portion 38. And a second shock absorbing member 48 provided in the housing. The shock absorbing members 46 and 48 of the present embodiment have an annular shape that surrounds the shaft portion 44a, specifically, a circular annular shape. The shock absorbing members 46 and 48 of the present embodiment are rubber members made of silicone or the like, that is, elastic bodies.

  The pressing member 44 is connected to the receiving portion 38 in a state where the shock absorbing members 46 and 48 are elastically compressed and deformed by pressing the fixed portion 42 together with the impact absorbing members 46 and 48 toward the receiving portion 38. . Accordingly, the fixed portion 42 is provided so as to be relatively movable in the Z direction with respect to the receiving portion 38 with elastic deformation in the Z direction of the shock absorbing members 46 and 48. The pressing member 44 fixes the fixed portion 42 so as to be movable relative to the receiving portion 38 in the Z direction by pressing the fixed portion 42 together with the impact absorbing members 46 and 48 toward the receiving portion 38. . The support structure 34 is elastically deformed in the Z direction of the shock absorbing members 46 and 48, and the support member 36 and the second functional component 24 integrated with the fixed part 42 are moved in the Z direction with respect to the base part 28. It can also be understood that it is supported so as to be relatively movable.

  When the first shock absorbing member 46 and the second shock absorbing member 48 are not elastically deformed, their height dimensions are set to be equal. The height dimension in the present specification refers to a dimension along the Z direction of the component referred to. The first shock absorbing member 46 is provided so as to protrude outward in the radial direction from the head 44 b of the pressing member 44 when viewed from the Z direction (viewed from the viewpoint of FIG. 6). Although not shown, the second shock absorbing member 48 is provided so as to protrude outward in the radial direction from the receiving portion 38 when viewed from the Z direction.

  The shaft portion 44a of the pressing member 44 has a stepped stopper portion 44e formed between a large diameter portion 44c on the proximal end side and a small diameter portion 44d on the distal end side. A male screw part is formed in the small diameter part 44d. The shaft portion 44a is screwed into the receiving portion 38 until the stopper portion 44e comes into contact with a seating surface 38a provided on the distal end surface of the receiving portion 38. The stopper portion 44e restricts the movement of the shaft portion 44a in the Z direction by contacting the seating surface 38a of the receiving portion 38. The pressing member 44 is disposed at a movement restriction position where movement in the Z direction with respect to the receiving portion 38 is restricted when the stopper portion 44 e hits the receiving portion 38. Thereby, the dispersion | variation in the space | interval from the head 44b resulting from a construction error to the receiving part 38 can be suppressed, and the elastic deformation amount of the impact-absorbing members 46 and 48 can be managed stably.

  The fixed portion 42 includes a first surrounding wall 52 protruding in the Z direction from the surface on one side in the Z direction of the fixed portion 42 and a first wall 52 protruding in the Z direction from the back surface on the other side of the fixed portion 42 in the Z direction. And two surrounding walls 54. The first surrounding wall 52 surrounds the first shock absorbing member 46 from the outside in the radial direction. The second surrounding wall 54 surrounds the second shock absorbing member 48 from the radially outer side. The surrounding walls 52 and 54 of the present embodiment surround the shock absorbing members 46 and 48 in a range extending over a half circumference around the central axis Ca (see FIG. 6) of the shaft portion 44a of the pressing member 44, and a part thereof is in the radial direction. Open to the outside.

  The height dimension La1 of the first shock absorbing member 46 of the present embodiment is set to a size equivalent to the height dimension Lb1 of the first surrounding wall 52 when the pressing member 44 is in the movement restricting position. The height dimension La2 of the second shock absorbing member 48 of the present embodiment is set to a size equivalent to the height dimension Lb2 of the second surrounding wall 54 when the pressing member 44 is in the movement restricting position.

  A radial clearance Lc <b> 1 is provided between the shaft portion 44 a of the pressing member 44 and the through hole 42 a of the fixed portion 42. The clearance Lc1 refers to a dimensional difference between the outer diameter of the shaft portion 44a and the inner diameter of the through hole 42a. Thereby, the fixed part 42 is provided so as to be relatively movable in the XY direction (radial direction) with respect to the base part 28.

(A) When the fixed portion 42 is moved relative to the base portion 28 in the XY direction, the support structure 34 has a structure in which the shaft portion 44a of the pressing member 44 hits the through hole 42a of the fixed portion 42 before The shock absorbing members 46 and 48 are configured to be sandwiched between the shaft portion 44a and the surrounding walls 52 and 54. In order to realize this, the support structure 34 of the present embodiment has, as a first condition, shock absorbing members 46 and 48 fitted inside the surrounding walls 52 and 54, and the shock absorbing members 46 and 48 are enclosed in the surrounding walls 52 and 54, respectively. 48 is in contact. As a second condition, a radial clearance Lc2 between the shaft portion 44a of the pressing member 44 and the shock absorbing members 46 and 48 is a diameter between the shaft portion 44a and the through hole 42a of the fixed portion 42. It is set to be smaller than the direction clearance Lc1. The clearance Lc2 refers to a dimensional difference between the outer diameter of the shaft portion 44a of the pressing member 44 and the inner diameters of the shock absorbing members 46 and 48.

  Thereby, when the fixed part 42 moves relative to the base part 28 in the XY direction, the shock absorbing members 46 and 48 can be elastically deformed in the XY direction. The support structure 34 is accompanied by elastic deformation of the shock absorbing members 46 and 48 in the XY directions, and the support member 36 and the second functional component 24 integrated with the fixed portion 42 are moved in the XY direction with respect to the base portion 28. It can be seen that it is supported so as to be relatively movable.

  FIG. 7A is a diagram for explaining a first load transmission path of the support structure 34, and FIG. 7B is a diagram illustrating an operation when an impact load is transmitted through the first load transmission path. is there. In FIG. 7A, an arrow Fa is attached in the direction in which the load is transmitted. The same applies to FIG. 8A and FIG. 9A.

  The support structure 34 has a load transmission path through which the Z-direction component of the impact load input to the base portion 28 can be transmitted from the base portion 28 to the second functional component 24. The load transmission path includes a first load transmission path capable of transmitting an impact load from the base portion 28 to the second functional component 24 toward one side (lower side in the figure) in the Z direction. The first load transmission path of the present embodiment passes through the receiving portion 38 of the base portion 28 → the head portion 44 b of the pressing member 44 → the first shock absorbing member 46 → the fixed portion 42 of the support member 36 → the second functional component 24. It is a route to do.

  The first shock absorbing member 46 is provided on this first load transmission path. The Z direction component of the impact load input to the base portion 28 is transmitted from the base portion 28 to the second functional component 24 via the impact absorbing member 46 on the first load transmission path. As shown in FIG. 7B, the first shock absorbing member 46 is a base portion for the second functional component 24 and the support member 36 when the Z-direction component of the shock load is transmitted on the first load transmission path. The Z direction component can be absorbed by itself deforming with the relative movement of 28 in the Z direction.

  FIG. 8A is a diagram for explaining a second load transmission path of the support structure 34, and FIG. 8B is a diagram illustrating an operation when an impact load is transmitted through the second load transmission path. is there. The load transmission path includes a second load transmission path through which an impact load directed to the other side in the Z direction (upper side in the drawing) is transmitted. The second load transmission path of the present embodiment is a path that passes through the receiving part 38 of the base part 28 → the second shock absorbing member 48 → the fixed part 42 of the support member 36 → the second functional component 24.

  The second shock absorbing member 48 is provided on the second load transmission path. The Z direction component of the impact load input to the base portion 28 is transmitted from the base portion 28 to the second functional component 24 via the second shock absorbing member 48 on the second load transmission path. As shown in FIG. 8B, the second shock absorbing member 48 is a base portion for the second functional component 24 and the support member 36 when the Z-direction component of the shock load is transmitted on the second load transmission path. The Z direction component can be absorbed by itself deforming with the relative movement of 28 in the Z direction.

  FIG. 9 is a diagram illustrating an operation when an impact load is transmitted through the third load transmission path of the support structure 34. The support structure 34 of the present embodiment has a third load transmission path capable of transmitting the XY direction component of the impact load input to the base portion 28 from the base portion 28 to the second functional component 24. The third load transmission path includes the receiving portion 38 of the base portion 28 → the shaft portion 44 a of the pressing member 44 → the first shock absorbing member 46, the second shock absorbing member 48 → the first enclosure of the fixed portion 42 of the support member 36. This is a route passing through the wall 52 and the second surrounding wall 54 → the second functional component 24.

  The shock absorbing members 46 and 48 are provided on such a third load transmission path. The XY direction component of the impact load input to the base portion 28 is transmitted from the base portion 28 to the second functional component 24 via the impact absorbing members 46 and 48 on the third load transmission path. When the XY direction component of the impact load is transmitted on the load transmission path, the shock absorbing members 46 and 48 are accompanied by relative movement of the base portion 28 in the XY direction with respect to the second functional component 24 and the support member 36. Is deformed, the XY direction component can be absorbed.

  The shock absorbing members 46 and 48 are provided so as to be deformable as the base portion 28 moves relative to the second functional component 24 and the support member 36 in the Z direction and the XY direction. It is considered that the impact load transmitted to the functional component 24 can be absorbed. The shock absorbing members 46 and 48 of the present embodiment can absorb the shock load by elastically compressing and deforming themselves.

  The effect will be described together with the operation of the functional device 26 described above. Consider a case where an impact load is input to the base portion 28. In the present embodiment, an impact load is input to the base portion 28 of the toilet seat 18 as the toilet seat 18 of the functional device 26 rotates. The main component of the impact load is a component along the Z direction of the base portion 28. When an impact load is input to the base portion 28, the base portion 28 moves relative to the second functional component 24 and the support member 36, and the shock absorbing members 46 and 48 are deformed along with the relative movement. As a result, the impact load transmitted from the base portion 28 to the second functional component 24 can be reduced by the impact absorbing members 46 and 48, and the second functional component 24 can be protected.

  Various impact loads that cause deformation such as torsional load, bending load, and shear load are input to the base portion 28. In the toilet apparatus 10 of this embodiment, before such an impact load is transmitted from the base portion 28 to the second functional component 24, the impact load is first transmitted to the support member 36 that supports the second functional component 24. A part of the load can be borne by the support member 36. Therefore, it is possible to reduce the impact load transmitted from the base portion 28 to the second functional component 24 rather than directly from the base portion 28 to the second functional component 24, and to protect the second functional component 24.

  From this point of view, it is preferable that the support member 36 has higher rigidity than any of the second functional components 24 with respect to rigidity against a predetermined type of load. Here, the “predetermined type of load” means, for example, at least one of a bending load, a torsion load, an axial load, and a shear load. This means that the degree of deformation of the support member 36 is smaller than that of the second functional component 24 when a predetermined type of the same load is applied to the support member 36 and the second functional component 24 individually. In the support member 36, the cross-sectional performance of the support member 36 and the elastic modulus of the material of the support member 36 are set so as to satisfy such conditions. Thereby, when a predetermined type of load is transmitted from the base portion 28 to the support member 36, the impact load transmitted to the second functional component 24 due to the deformation is suppressed by suppressing the deformation of the support member 36. The second functional component 24 can be further protected.

  Further, the shock absorbing members 46 and 48 are provided so as to be deformable as the base portion 28 moves relative to the support member 36. Therefore, the impact load reduced by the impact absorbing members 46 and 48 is transmitted from the base portion 28 to the support member 36. For this reason, the deformation of the support member 36 due to the impact load can be suppressed, and the impact load transmitted to the second functional component 24 due to the deformation can be reduced.

  The support member 36 supports the plurality of second functional components 24. Therefore, by sharing the single support member 36 among the plurality of second functional components 24, the number of components is reduced, and the impact absorbing members 46 and 48 absorb the impact load, thereby the plurality of second functional components 24. Can be protected.

  The support structure 34 includes a pressing member 44 connected to the receiving portion 38 in a state where the impact absorbing members 46 and 48 and the fixed portion 42 are pressed from the side opposite to the receiving portion 38. Therefore, the load component in the Z direction can be absorbed by the shock absorbing members 46 and 48 while fixing the fixed portion 42 integrated with the second functional component 24 so as to be relatively movable in the Z direction.

  Since the impact absorbing members 46 and 48 include the first impact absorbing member 46 and the second impact absorbing member 48, the following advantages are obtained. As shown in FIG. 7B, when an impact load in the pressing direction Za is input to the base portion 28, the first shock absorbing member 46 between the pressing member 44 and the fixed portion 42 is elastically deformed, The impact load is absorbed. As shown in FIG. 8B, when the impact load in the counter pressing direction Zb is input to the base portion 28, the second shock absorbing member 48 between the fixed portion 42 and the receiving portion 38 is elastically deformed. The impact load is absorbed. That is, any impact load in the Z direction can be absorbed by the impact absorbing members 46 and 48, and the second functional component 24 can be more effectively protected.

  As shown in FIG. 5, elastic repulsive forces Fb in opposite directions are applied to the fixed portion 42 from each of the first shock absorbing member 46 and the second shock absorbing member 48. The fixed portion 42 is stopped at an initial position where the elastic repulsive force Fb applied from each of the shock absorbing members 46 and 48 can be balanced. When the fixed portion 42 moves relative to the base portion 28 in the Z direction due to the impact load transmitted from the base portion 28 to the fixed portion 42, the fixed portion 42 is elastically repelled by the impact absorbing members 46 and 48. It vibrates in the Z direction until it stops at the initial position by Fb. The impact absorbing members 46 and 48 are elastically deformed in the course of the vibration of the fixed portion 42 as described above, so that the impact load transmitted to the fixed portion 42 is also absorbed by the shock absorbing members 46 and 48.

  The fixed portion 42 has surrounding walls 52 and 54 that surround the shock absorbing members 46 and 48, and is provided so as to be movable relative to the base portion 28 in the radial direction. Therefore, when the fixed portion 42 moves relative to the base portion 28 in the radial direction, the shock absorbing members 46 and 48 are elastically deformed between the shaft portion 44 a of the pressing member 44 and the surrounding walls 52 and 54. As a result, the impact load transmitted in the X and Y directions from the base portion 28 to the fixed portion 42 can be absorbed by the impact absorbing members 46 and 48.

  As shown in FIG. 9, when the shock absorbing members 46 and 48 are elastically deformed in the XY direction, the fixed portion 42 is returned to the position before the elastic deformation of the shock absorbing members 46 and 48 in the XY direction. The elastic repulsive force Fc is applied from the shock absorbing members 46 and 48. Therefore, even when the fixed portion 42 moves relative to the base portion 28 in the XY direction, the fixed portion 42 can be brought close to the position before the relative movement by the elastic repulsive force Fc applied from the shock absorbing members 46 and 48. . As a result, it is possible to prevent a large displacement of the second functional component 24 before and after the impact load is applied.

  The base portion 28 is provided on the toilet seat 18 that is movably attached to the toilet body 14. Therefore, even when an impact load is frequently input to the base portion 28 as the toilet seat 18 moves, the second functional component 24 can be protected as described above.

  Next, other features of the functional device 26 will be described. Please refer to FIG. On the radially outer side with respect to the head portion 44b of the pressing member 44, when the fixed portion 42 is moved relative to the base portion 28 in the Z direction, a first shock absorbing member 46 is released for releasing the first shock absorbing member 46 in the Z direction. One escape space 56 is provided. The first clearance space 56 of the present embodiment is provided at a location that overlaps with a range over the entire circumference of the outer periphery of the first shock absorbing member 46 when viewed from the Z direction.

  On the radially outer side with respect to the receiving portion 38, a second escape space 58 for allowing the second shock absorbing member 48 to escape in the Z direction when the fixed portion 42 moves relative to the base portion 28 in the Z direction. Is provided. The second clearance space 58 of the present embodiment is provided at a location that overlaps with a range over the entire circumference of the outer periphery of the second shock absorbing member 48 as viewed from the Z direction.

  When the fixed portion 42 moves relative to the base portion 28, the shock absorbing members 46 and 48 are compressed and deformed between the pressing member 44 and the receiving portion 38 and the fixed portion 42. At this time, the shock absorbing members 46 and 48 try to compressively deform in the X and Y directions, and the deformation of the shock absorbing members 46 and 48 is restricted by the surrounding walls 52 and 54 in the process. Here, according to the present embodiment, even in a situation where the deformation of the shock absorbing members 46 and 48 is restricted by the surrounding walls 52 and 54 as described above, FIG. 7B and FIG. As shown, the impact absorbing members 46 and 48 can be elastically deformed to escape into the escape spaces 56 and 58. As a result, by increasing the amount of elastic deformation of the impact absorbing members 46, 48, the impact load absorbing ability of the impact absorbing members 46, 48 can be enhanced.

  The second shock absorbing member 48 supports the fixed portion 42 between the fixed portion 42 and the receiving portion 38. The pressing member 44 is connected to the receiving portion 38 in a state where the second shock absorbing member 48 is compressed and deformed.
