Description

  Aspects of the invention generally relate to lining units.

  There is a lining unit which is installed and used behind a stool-type toilet bowl. The lining unit improves the appearance of the toilet room, for example, by covering a water supply pipe, a tank and the like connected to the toilet bowl. The lining unit includes, for example, a substantially rectangular frame-like frame, a front plate that covers the front of the frame, and a top plate that covers the upper side of the frame.

  The front plate is attached to the frame by engagement without using fixing members such as screws. Thus, the front plate can be removed relatively easily at the time of maintenance and the like, and the fixing member and the like are not exposed to the outside, so that the appearance of the lining unit can be improved.

  In such a lining unit, it has also been proposed to provide a front plate with a backrest for supporting the back of the user seated on the toilet bowl (for example, Patent Document 1). This allows the user seated in the proper orientation with the back facing the lining unit to lean on the backrest and add to the use.

  However, there are not many users who use it in the reverse direction facing the lining unit side. In such a case, there is a possibility that the user grips the backrest and applies a force to release the engagement between the frame and the front plate, and the front plate may be accidentally removed from the frame. The sudden removal of the front plate may cause a fall of the user seated in the opposite direction.

  On the other hand, if the front plate is strictly fixed to the frame in order to prevent accidental removal of the front plate, it takes time and effort to remove the front plate at the time of maintenance and the like. Therefore, in the lining unit, it is desirable that the front plate can be easily removed from the frame at the time of maintenance while suppressing the detachment of the front plate in a state in which a force is applied to the backrest.

  Thus, the hook portion 54a is engaged with the second extension portion 64b, and the lower end of the adjustment screw 54d is abutted against the first extension portion 64a. Thereby, as described above, the lower front plate 18 can be attached to the lower portion of the front surface portion 34 in a state of being engaged from above with respect to the frame 12 and the movement in the lower and front-back directions is restricted. Further, in the lower front plate 18, the vertical position of the lower front plate 18 can be adjusted by rotating the adjustment screw 54d to adjust the length of the portion protruding downward from the female screw 54c.

  The configurations of the lower engagement portion 56 of the lower front plate 18, the upper engagement portion 50 of the upper front plate 14, and the lower engagement portion 52 of the upper front plate 14 are the same as those of the upper engagement portion 54 of the lower front plate 18. Since the configuration is substantially the same as that of the configuration, the detailed description is omitted.

  The lower engaging portions 52, 56 may be provided with adjusting screws 54d in the same manner as the upper engaging portions 50, 54, and like the lower engaging portions 52 shown in FIG. 5, the adjusting screws 54d. May be omitted. That is, the restriction of the downward movement and the adjustment of the position in the vertical direction may be performed only by the upper engaging portions 50 and 54.

  As shown in FIG. 5, the lining unit 10 further includes a regulating member 70. The regulating member 70 regulates the upward movement of the lower front plate 18. The restriction member 70 is provided, for example, on the front surface portion 34 of the frame 12. The restricting member 70 is disposed above the adjustment screw 54 d of the upper engaging portion 54 of the lower front plate 18 and abuts on the upper end of the adjustment screw 54 d to restrict the upward movement of the lower front plate 18.

  The restriction member 70 is attached to the frame 12 after, for example, the lower front plate 18 is attached to the frame 12 and the vertical position of the lower front plate 18 is adjusted with the adjustment screw 54 d. Thereby, the upward movement of the lower front plate 18 is restricted.

  The configuration of the regulating member 70 is not limited to the above configuration. The restricting member 70 may be, for example, a screw or the like for fixing the lower front plate 18 to the frame 12. The configuration of the restricting member 70 may be any configuration capable of restricting the upward movement of the lower front plate 18.

  However, as described above, by being in contact with the upper end of the adjustment screw 54d, for example, the restriction member 70 can be covered with the upper front plate 14 and the lower front plate 18. It is possible to suppress the exposure of the restricting member 70 to the outside, and restrict the upward movement of the lower front plate 18 without reducing the appearance of the lining unit 10.

  In the lining unit 10 according to the present embodiment, when the tank or the like housed inside is maintained, first, the device body of the sanitary washing device 6 is removed from the toilet 4 to expose the joining member 22 forward. Thereafter, the joining member 22 is removed to release the joined state of the upper front plate 14 and the fixing portion 20. This enables the upper front plate 14 to move upward. It is possible to release the engaged state of each upper engaging portion 50 and each lower engaging portion 52. Accordingly, the upper front plate 14 can be removed from the frame 12. When the upper front plate 14 is removed from the frame 12, the internal space of the frame 12 is exposed to the front. Thereby, it becomes possible to access from a front side the tank etc. which were accommodated in the inside of the flame | frame 12, and maintenance of a tank etc. can be performed.

  As described above, in the lining unit 10 according to the present embodiment, when the joining member 22 joins the upper front plate 14 and the fixing portion 20, the upward movement of the upper front plate 14 is suppressed. Thereby, even if force is applied to the backrest 16, detachment of the upper front plate 14 from the frame 12 can be suppressed. Then, at the time of maintenance, the joining member 22 detachably attached to the fixing portion 20 is removed from the front side of the upper front plate 14. This enables removal of the upper front plate 14 from the frame 12. Further, at this time, by making the joint member 22 a knurled screw, it is not necessary to use a tool or the like, and the joint member 22 can be removed more easily.

  In this manner, the upper front plate 14 can be easily removed simply by removing the joining member 22 from the front side. Therefore, the lining unit 10 capable of easily removing the upper front plate 14 from the frame 12 at the time of maintenance while suppressing removal of the upper front plate 14 in a state where the backrest 16 is applied with force is provided.

  In the above embodiment, the lining unit 10 includes one through hole 40 a and one joint member 22. The lining unit 10 may include a plurality of through holes 40 a and a plurality of joining members 22.

  In the lining unit 10, it is not necessary to remove the top plate 24 when performing maintenance. Therefore, it is possible to fill the space that is open between the top plate 24 and the wall surface of the toilet room with caulking material or the like. Thereby, it is possible to suppress that water, paper, etc. get into the inside of the frame 12 from the gap that is open between the top plate 24 and the wall surface of the toilet room. In other words, in the lining unit 10, even if the gap around the top plate 24 is filled with caulking material etc., it is possible to save the trouble of removing caulking material etc around the top plate 24 one by one at the time of maintenance etc. .

  The lining unit 10 further includes a restricting member 70 that restricts the upward movement of the lower front plate 18. Thus, in a state where the upper front plate 14 is joined to the lower front plate 18 via the joining member 22 and the fixing portion 20, the upper front plate 14 and the lower front plate 18 move upward together, and It can be suppressed that the engaged state is released. Therefore, the detachment of the upper front plate 14 from the frame 12 when a force is applied to the backrest 16 can be suppressed more appropriately.

  Further, in the lining unit 10, the through holes 40 a are disposed below the backrest 16 and above the toilet bowl 4. As a result, the joining member 22 can be removed more easily than in the case where the through hole 40 a and the joining member 22 are disposed at a position hidden by the backrest 16. In addition, the through hole 40a and the joining member 22 are easily hidden by the backrest 16 or the like when viewed from the user standing up toward the rear side. Therefore, the appearance of the lining unit 10 can be improved even when the through holes 40 a and the joining members 22 are provided.

  Further, in the lining unit 10, the through hole 40a is disposed below the upper end 6a of the sanitary washing device 6 mounted on the toilet bowl 4. As a result, when viewed from the user standing up toward the rear side, the through hole 40a and the joining member 22 are easily hidden by the sanitary washing device 6, and the appearance of the lining unit 10 can be further improved.

  Further, in the lining unit 10, the through holes 40 a are disposed between the width W 1 of the sanitary washing device 6. As a result, when viewed from the user standing up toward the rear side, the through hole 40a and the joining member 22 are easily hidden by the sanitary washing device 6, and the appearance of the lining unit 10 can be further improved.

  In the lining unit 10, the through holes 40a are disposed between the width W2 in the left-right direction of each attachment portion 16b of the backrest 16. Thus, the strength of the upper front plate 14, the fixing portion 20, the joining member 22, and the like can be enhanced with respect to the force applied to the backrest 16. For example, in the case where the through hole 40a is located outside the width W2 in the left-right direction, when a force is applied to the backrest 16, a force that twists the shaft at the portion of the through hole 40a is the upper front plate It joins 14 and so on. By arranging the through holes 40 a between the width W 2, it is possible to suppress such a force from being applied to the upper front plate 14 or the like, and to enhance the strength of the upper front plate 14 or the like.

  Then, the through hole 40 a is disposed at a position overlapping the center CL in the left-right direction of the backrest 16. Thereby, the strength of the upper front plate 14, the fixing portion 20, the joining member 22 and the like can be further enhanced against the force applied to the backrest 16.
