Description

  Aspects of the present invention generally relate to a toilet seat device, and more specifically, to a toilet seat device in which a toilet seat and a toilet lid are detachable.

  In some toilet seat devices, for example, a toilet seat and a toilet lid are attached to a casing that incorporates functional units such as a local cleaning function, a deodorizing function, and a local drying function. Since the toilet seat and the toilet lid are members that a person sits on and is exposed to dust, dirt or splashed water may adhere to the toilet seat and the toilet lid, respectively. For this reason, in the toilet seat device as described above, when wiping and cleaning the toilet seat and the toilet lid, it is difficult to perform the operation if the toilet seat and the toilet lid are connected to the casing. Therefore, the toilet seat and the toilet lid can be removed from the casing. It is convenient if you can.

  Therefore, there is a toilet seat and toilet lid mounting structure in which a hinge block of a toilet seat is inserted into a protruding portion provided on a casing (Patent Documents 1 and 2). Further, by inserting a shaft pin provided to the wall surface of the support portion so as to be able to advance and retreat through a shaft hole provided in the toilet seat and the toilet lid, the toilet seat and the toilet lid rotate with respect to the support portion around the shaft pin. There is a toilet device that is pivotally supported (Patent Document 3). In the mounting structures described in Patent Documents 1 and 2, the toilet block is mounted on the casing by inserting the hinge block of the toilet seat into the protrusion of the casing and then engaging the hinge block with the protrusion. Thereby, a toilet seat and a toilet lid can be removed from a casing, or can be attached to a casing.

  However, the user may forget to engage the hinge block with the protrusion when the toilet seat and the toilet lid are attached to the casing. Even in this case, when the user sits on the toilet seat, the back surface of the toilet seat pushes the hinge block, so that the hinge block is generally engaged with the protrusion. However, if the upper surface of the Western-style seating toilet that supports the lower surface of the toilet seat is uneven, the hinge block is not engaged with the protrusion, and for example, when the user sits vigorously at the front end of the toilet seat, the hinge The block may come off the protrusion.

  The toilet seat device 10 according to the present embodiment includes a casing 100, a toilet seat 200, a toilet lid 300, a hinge block 410 and a rotation block 420 that pivotally support and connect the toilet seat 200 and the toilet lid 300. Prepare.

  As shown in FIG. 1, the casing 100 has a protrusion (mounting portion) 110 formed by partially protruding the surface side. The casing 100 is, for example, a sanitary washing function unit having a water discharge nozzle (not shown) that ejects water toward the “butt” of the user sitting on the toilet seat 200, or the “butt” of the user sitting on the toilet seat 200. Built-in hot air drying function unit that blows hot air toward the air, etc., and other functional units of other deodorizing units and indoor heating units. However, in the present invention, the sanitary washing function unit and other additional function units are not necessarily provided.

  The toilet seat 200 has a rotation block insertion portion 210 into which a rotation block 420 can be inserted at a base end portion thereof. Moreover, the toilet seat 200 has the support part 220 on the surface, as represented to FIG. Then, the toilet seat 200 is supported on the upper surface of the toilet bowl by the support portion 220 coming into contact with the upper surface of a western-style seat toilet (not shown) (hereinafter simply referred to as “toilet bowl” for convenience of explanation). Further, like the toilet seat 200, the toilet lid 300 has a rotation block insertion portion 310 into which the rotation block 420 can be inserted at the base end portion.

  As shown in FIG. 2, the rotation block 420 includes a hinge body 421 having an opening / closing unit (not shown) and a hinge shaft 423, and the hinge body 421 is connected to the hinge shaft 423. And can be rotated freely. Note that the opening / closing unit of the hinge body 421 can provide resistance to the operations of the toilet seat 200 and the toilet lid 300, and can, for example, moderate the operation when the toilet seat 200 and the toilet lid 300 are closed.

The hinge block 410 has a hinge block main body 411, and a recess 412 into which the protrusion 110 of the casing 100 can be inserted is provided at the bottom of the hinge block main body. The protrusion 110 may be provided with a recess so that the hinge block 410 can be inserted into the recess. Alternatively, a recess as a mounting portion may be formed in the casing 100 instead of the protrusion 110, and the hinge block 410 may be inserted into the recess.
The hinge block main body 411 has a support hole 413 for inserting and fixing the hinge shaft 423 of the rotation block 420. In the connecting structure shown in FIG. 2, one of the rotating block insertion portions 210 provided on the base end portion of the toilet seat 200 (left side in the connecting structure shown in FIG. 2) is rotated integrally with the hinge body 421. The other rotation block insertion portion 210 (on the right side in the connecting structure shown in FIG. 2) is pivotally supported with respect to the hinge body 421. Further, the rotation block insertion portion 310 on the opposite side to the fixed rotation block insertion portion 210 (on the right side in the connecting structure shown in FIG. 2) is fixed so as to rotate integrally with the hinge body 421, and the other ( The rotating block insertion portion 310 on the left side in the connecting structure shown in FIG. 2 is pivotally supported with respect to the hinge body 421.

  In this manner, the toilet seat 200, the toilet lid 300, the hinge block 410, and the rotation block 420 are integrated. Then, in the integrated state, as shown by an arrow A shown in FIG. 2, the recess 412 of the hinge block 410 is inserted into the protrusion 110 of the casing 100, so that the protrusion 110 of the casing 100 and the rotation block The insertion portions 210 and 310 can be connected to each other via the hinge block 410 and the rotation block 420. According to this, the toilet seat 200 and the toilet lid 300 can be attached to the casing 100. On the other hand, the toilet seat 200 and the toilet lid 300 can be removed from the casing 100 by pulling up the recess 412 of the hinge block 410 from the protrusion 110 of the casing 100.

FIG. 3 is a schematic perspective view illustrating a connecting structure of the hinge block and the protrusion.
As described above with reference to FIG. 2, the hinge block 410 has a hinge block body 411, and the hinge block body 411 has a recess 412 and a support hole 413. In addition, the hinge block 410 includes a hinge cover (cover member) 415 as illustrated in FIG. 3. The hinge cover 415 is pivotally supported with respect to the hinge block main body 411 at the shaft support portion 417, and can rotate with respect to the hinge block main body 411 about the shaft support portion 417. Further, the hinge cover 415 has an engagement convex portion (engagement portion) 416 protruding toward the hinge block main body 411 in the vicinity of the lower end portion thereof.

  The shaft support 417 is provided with an elastic body 418 such as a “spring”, for example. The elastic body 418 biases the lower end portion of the hinge cover 415 toward the hinge block main body 411 side. That is, the engagement convex portion 416 is urged toward the hinge block main body 411 side by the elastic body 418 provided on the shaft support portion 417. Therefore, when a portion (pressing portion) above the shaft support portion 417 in the hinge cover 415 is pushed in the direction of the arrow B shown in FIG. 3, the lower end portion or the engaging convex portion 416 of the hinge cover 415 is removed from the elastic body 418. Rotating about the shaft support 417 in the direction of the arrow C shown in FIG. On the other hand, when the pressing of the upper portion of the hinge cover 415 with respect to the shaft support portion 417 is stopped, the lower end portion of the hinge cover 415 or the engaging convex portion 416 receives the urging force from the elastic body 418, and the arrow shown in FIG. It rotates about the shaft support 417 in the opposite direction to C.

  As shown in FIG. 3, the protrusion 110 of the casing 100 has an engagement recess (engagement portion) 111 that retreats inward from the surface thereof. The engagement recess 111 is slightly larger than the outer shape of the engagement protrusion 416 of the hinge cover 415. Therefore, when the hinge block 410 is inserted into the protrusion 110, the engagement protrusion 416 of the hinge cover 415 is inserted into the engagement recess 111 of the protrusion 110. That is, when the hinge block 410 is inserted into the protrusion 110, the engaging convex portion 416 and the engaging concave portion 111 are engaged. This is because the elastic body 418 provided in the shaft support portion 417 biases the engaging convex portion 416 toward the hinge block main body 411 side, that is, the engaging concave portion 111 side. As a result, the hinge block 410 cannot be removed upward from the protrusion 110.

  According to this, when the hinge block 410 is inserted into the protrusion 110, the lock is automatically applied to prevent it from coming off. Therefore, the toilet seat 200 and the toilet lid 300 integrated with the hinge block 410 via the rotation block 420 can be prevented from being detached from the casing 100. On the other hand, when the toilet seat 200 and the toilet lid 300 are removed from the casing 100, the portion (pressing portion) above the shaft support portion 417 in the hinge cover 415 is pushed in the direction of arrow B shown in FIG. The toilet seat 200 and the toilet lid 300 can be removed from the casing 100 by lifting. Hereinafter, this will be described in more detail with reference to the drawings.

FIG. 4 is a schematic cross-sectional view illustrating a state in which the engagement convex portion and the engagement concave portion are locked.
FIG. 5 is a schematic cross-sectional view showing a state in which the lock between the engagement convex portion and the engagement concave portion is released.
The elastic body 418 provided on the shaft support portion 417 urges the portion of the hinge cover 415 above the shaft support portion 417 to the opposite side of the hinge block main body 411 as indicated by an arrow D shown in FIG. . As a result, as indicated by an arrow E shown in FIG. 4, the lower end portion or the engaging convex portion 416 of the hinge cover 415 is urged toward the hinge block body 411 with the shaft support portion 417 as the center.

  Therefore, when the hinge block 410 integrated with the toilet seat 200 and the toilet lid 300 is inserted into the protrusion 110 of the casing 100 via the rotation block 420, the engagement convex portion of the hinge cover 415 as shown in FIG. 416 and the engagement recess 111 of the protrusion 110 are automatically engaged. This is because the engaging convex portion 416 is urged toward the hinge block main body 411 side, that is, the engaging concave portion 111 side, as described above. Therefore, when the hinge block 410 is inserted into the protrusion 110, the engagement convex portion 416 and the engagement concave portion 111 are automatically engaged and locked.

  According to this, when the user attaches the toilet seat 200 and the toilet lid 300 to the casing 100, the user does not forget to engage (lock) the hinge block 410 with the protrusion 110. That is, when the user attaches the toilet seat 200 and the toilet lid 300 to the casing 100, the hinge block 410 can be reliably locked to the protrusion 110. Therefore, even when the user sits vigorously at the front end of the toilet seat 200 after attaching the toilet seat 200 and the toilet lid 300 to the casing 100, the hinge block 410 is disengaged from the protrusion 110, that is, the toilet seat 200 and the toilet lid 300 are The release from the casing 100 can be suppressed. Further, the safety can be further improved, and a lock mechanism for preventing the toilet seat 200 and the toilet lid 300 from coming off can be provided at a lower cost.

  On the other hand, when removing the toilet seat 200 and the toilet lid 300 from the casing 100, the user first opens the toilet seat 200 and the toilet lid 300 (see FIG. 1) as shown in FIG. Subsequently, the user pushes a portion of the hinge cover 415 above the shaft support portion 417 in the direction of the arrow B shown in FIG. 5 or 3 while resisting the urging force from the elastic body 418. If it does so, the engagement convex part 416 of the hinge cover 415 will rotate centering | focusing on the axial support part 417 in the direction of the arrow C represented to FIG. 5 or FIG. At this time, as shown in FIG. 5, the engagement between the engagement convex portion 416 and the engagement concave portion 111 is released, and the lock is released. The user can remove the toilet seat 200 and the toilet lid 300 from the casing 100 by lifting the toilet seat 200 and the toilet lid 300 in this state.

  According to this, the user can easily unlock the engagement convex portion 416 and the engagement concave portion 111 by pressing a portion of the hinge cover 415 above the shaft support portion 417. Therefore, even when the toilet seat 200 and the toilet lid 300 are removed from the casing 100, the user can easily remove the toilet seat 200 and the toilet lid 300 from the casing 100 while releasing the lock.

  In the present embodiment, the case where the engaging convex portion 416 is provided on the hinge cover 415 and the engaging concave portion 111 is provided on the protruding portion 110 has been described as an example. However, the present invention is not limited thereto. . The engaging convex part 416 may be provided on the protrusion 110, and the engaging concave part 111 may be provided on the hinge cover 415. That is, the engaging convex portion 416 is provided on one of the hinge cover 415 and the protruding portion 110, and the engaging concave portion 111 is provided on either the hinge cover 415 or the protruding portion 110, and the engaging convex portion 416. And the engaging recess 111 need only have shapes that can engage with each other.

  Moreover, although the hinge block main body 411 of the hinge block 410 has the recessed part 412 inserted in the protrusion 110, it is not limited only to this, The protrusion 110 may have a recessed part. That is, the protrusion 110 may have a recess into which the hinge block body 411 can be inserted. Also by this, it is possible to prevent the toilet seat 200 and the toilet lid 300 from being detached from the casing 100 by inserting the hinge block 410 into the recess of the protrusion 110. This will be described in detail later.

Next, a modification of the present embodiment will be described with reference to the drawings.
FIG. 6 is a schematic perspective view illustrating a connecting structure of a hinge block and a protrusion of a toilet seat device according to a modification of the present embodiment.
FIG. 7 is a schematic cross-sectional view showing the internal structure of the connection between the hinge block and the protrusion of this modification.

  The hinge block 510 of this modification has a hinge block main body 511 similarly to the hinge block 410 shown in FIG.

  As described above with reference to FIG. 3, the protrusion of the casing may have a recess into which the hinge block can be inserted. That is, the protrusion 630 of this modification has a recess 631 into which the hinge block 530 can be inserted. The protrusion 630 has an engagement hole 633 that can engage with a protrusion 535 provided on the hinge block 520. As shown in FIGS. 9A and 9B, the engagement holes 633 are provided one by one on the side surfaces facing each other in the protrusion 630.

  On the other hand, the hinge block 530 of this modification does not have a recess as described above with reference to FIGS. The hinge block 530 of the present modified example has a protruding portion 531 that is formed of an elastic body such as “rubber” at the lower end thereof and protrudes downward. On the side surface of the protrusion 531, there is a protrusion 535 that can be engaged with the engagement hole 633 of the protrusion 630. One protrusion 535 is provided on each of the left and right side surfaces of the protrusion 531. In addition, an elastic body 533 such as a “spring” is provided between the protrusions 535 provided on the left and right side surfaces of the protruding portion 531 as shown in FIGS. . Therefore, the projection 535 can move in the substantially vertical direction of the side surface of the hinge block 530 and is moved to the outer side (surface side) of the hinge block 530 by the elastic body 533 in the same manner as the modification described above with reference to FIGS. It is energized towards.

  When the user inserts the hinge block 530 into the recess 631 of the protrusion 630, the protrusion 535 receives an external force from the protrusion 630 and moves to the inside of the hinge block 530 or the protrusion 630. Then, the hinge block 530 is further inserted below the recess 631 of the protrusion 630. When the hinge block 530 is inserted into the recess 631 of the protrusion 630 until the protrusion 535 provided on the hinge block 530 substantially coincides with the position of the engagement hole 633, the protrusion 535 passes through the engagement hole 633. Move outside 630. Then, the protrusion 535 and the engagement hole 633 are automatically engaged and locked.

  According to this modification, since the protrusion 531 is provided on the hinge block 530 and the recess 631 that is opened upward is provided on the protrusion 630, the user visually observes the insertion portion (the recess 631). It is easy to insert the hinge block 530 into the protrusion 630. Further, similarly to the modification described above with reference to FIG. 8, the protrusion 535 and the engagement hole 633 are engaged with each other on the left and right side surfaces of the hinge block 530 and the protrusion 630, and the lock is more reliably applied. That is, it can suppress more reliably that the toilet seat 200 and the toilet lid 300 remove | deviate from the casing 100. FIG. Further, with respect to other effects, the same effects as those described above with reference to FIGS. 3 to 5 can be obtained.

  On the other hand, when removing the toilet seat 200 and the toilet lid 300 from the casing 100, the user first pushes the projections 535 on the left and right side surfaces to the inside of the projection 630 substantially simultaneously with, for example, fingers. Then, the protrusions 535 on the left and right side surfaces move to the inside of the protrusion 630, the engagement between the protrusion 535 and the engagement hole 633 is released, and the lock is released. The user can remove the toilet seat 200 and the toilet lid 300 from the casing 100 by lifting the toilet seat 200 and the toilet lid 300 in this state.

  As described above, according to the present embodiment, when the hinge block 410 is inserted into the protrusion 110, the lock is automatically applied to prevent the removal. The same applies to the modified examples described above with reference to FIGS. Therefore, when the user attaches the toilet seat 200 and the toilet lid 300 to the casing 100, the user does not forget to engage (lock) the hinge block 410 with the protrusion 110. That is, when the user attaches the toilet seat 200 and the toilet lid 300 to the casing 100, the hinge block 410 can be reliably locked to the protrusion 110. Therefore, even when the user sits vigorously at the front end of the toilet seat 200 after attaching the toilet seat 200 and the toilet lid 300 to the casing 100, the hinge block 410 is disengaged from the protrusion 110, that is, the toilet seat 200 and the toilet lid 300 are The release from the casing 100 can be suppressed. Further, the safety can be further improved, and a lock mechanism for preventing the toilet seat 200 and the toilet lid 300 from coming off can be provided at a lower cost.
