JP 2006-37408 A

  In the device described in Patent Literature 1, wear and tear may occur due to the concave and convex portions coming into contact with other portions each time the toilet lid member is opened and closed. Further, the resistance when the convex portion is fitted into the concave portion or when the convex portion is removed from the concave portion becomes the resistance when the toilet lid member is rotated.

  An object of the present invention is to improve the durability of the mechanism and the operability of the toilet lid member in a toilet seat / toilet lid unit provided with a mechanism for maintaining the toilet lid member positioned at the fully open position. .

In order to solve the above-described problems, a toilet seat / toilet lid unit according to the present invention is a toilet seat member that is rotatable with respect to a toilet bowl, a toilet lid member that is rotatable with respect to the toilet seat member, and a toilet seat that is fixed to the toilet bowl. And a stopper member supported by the fixing member. On the side surface of the toilet lid member, an engaged portion that is moved by the rotation of the toilet lid member is formed. An engaging portion that is biased in a direction to engage with an engaged portion formed on the toilet lid member when the toilet lid member is located at the fully open position, and is formed on the toilet lid member. The toilet lid member is pivotally supported by the toilet seat member by engaging the pivot shaft portion or the bearing portion thus formed with the bearing portion or the pivot shaft portion formed on the toilet seat member. And the engaged portion is a rotating shaft portion or a shaft formed on the toilet lid member. Is formed in part, the fixing member is, so that the engaging portion is not in contact with a portion other than portions where the flights are formed in the lid member a definitive rotational shaft or bearing part the engaged portion is formed And a restricting portion for restricting the stopper member .

  In the rotation range of the toilet lid member with respect to the toilet seat member, the rotation shaft portion formed on the toilet lid member or the portion facing the engagement portion on the outer peripheral surface of the bearing portion is compared to other portions. The outer diameter should be small.

  The engaging portion is positioned below a rotation center axis of the toilet lid member, and the engaged portion is configured to rotate the toilet lid member in a state where the toilet lid member is located at a fully closed position. It is good to be located behind the central axis.

  In the toilet seat / toilet lid unit according to the present invention, the engaging portion of the stopper member is engaged with the engaged portion of the toilet lid member, so that the toilet lid member is located at the fully open position when the toilet seat member is rotated. Is kept from moving. The engaging portion is biased in a direction to engage with the engaged portion. According to this configuration, when the engaging portion and the engaged portion are engaged, and when the engagement between the engaging portion and the engaged portion is released, the engaging portion and the engaged portion itself are removed. It is possible to suppress an excessive force from acting. Therefore, the durability of the toilet lid maintenance mechanism for maintaining the toilet lid member in the fully open position is improved as compared with the conventional case, and the resistance force received from the mechanism when the toilet lid member is rotated is reduced. The operability of the toilet lid member is improved. In addition, since the engaged portion is provided on the side surface of the toilet lid member, the engaged portion (the toilet lid maintaining mechanism) is not conspicuous and is excellent in design. Furthermore, cleaning is easy.

  The engaged portion can be formed on a rotation shaft portion or a bearing portion for rotatably supporting the toilet lid member with respect to the toilet seat member. That is, the element which comprises the toilet lid maintenance mechanism for maintaining a toilet lid member in a fully open position can be constructed | assembled into the element for supporting a toilet lid member rotatably with respect to a toilet seat member.

  If a restricting portion that prevents the engaging portion from coming into contact with a portion other than the portion where the engaged portion is formed is provided, the biased engaging portion comes into contact with the rotating shaft portion or the bearing portion. Therefore, it is possible to prevent an increase in resistance when the toilet lid member is rotated.

  Within the rotation range of the toilet lid member relative to the toilet seat member, if the portion facing the engagement portion on the outer peripheral surface of the rotation shaft portion or the bearing portion has a smaller outer diameter than the other portions, The engaging portion (stopper member) can be arranged closer to the center of the rotating shaft portion or the bearing portion, which leads to downsizing of the entire unit.

  In a state where the engaging portion is located below the rotation center axis of the toilet lid member and the toilet lid member is located at the fully closed position, the engaged portion is located behind the rotation center axis of the toilet lid member. As described above, when the engaging portion and the engaged portion are arranged, it becomes difficult for the user to see the engaging portion and the engaged portion, and the design of the unit is improved.

  Hereinafter, a toilet seat / toilet lid unit 1 according to an embodiment of the present invention will be described in detail with reference to FIGS. In the following description, the width direction refers to the direction along the rotation center axis C of the toilet seat / toilet lid unit 1, the vertical direction refers to the direction along the gravity direction, and the front-rear direction refers to the width direction and the vertical direction. It is assumed that the direction is orthogonal (the rear of the toilet bowl 90 is the rear). In addition, the shape and the like of each member in the following description is in the original position (toilet seat use position for the toilet seat member 20 and fully closed position for the toilet lid member 30) unless otherwise specified. It shall mean the shape in the state.

  A toilet seat / toilet lid unit 1 according to an embodiment of the present invention shown in FIGS. 1 and 4 as a whole includes a fixing member 10, a toilet seat member 20, a toilet lid member 30, and a stopper member 40. Hereinafter, each configuration will be described in detail.

  The fixing member 10 is a member that is fixed to the rear upper surface of the toilet bowl 90. Since the attachment structure of the fixing member 10 to the toilet bowl 90 may be any structure, detailed description thereof is omitted. The fixing member 10 includes a base portion 11, an upright portion 12, and a support portion 13 (see FIG. 7). The base portion 11 is a flat plate portion installed on the upper surface of the toilet bowl 90. The upright portion 12 is a portion that extends straight upward from the rear edge of the base portion 11 in the direction of gravity. The support portion 13 is a portion that extends forward from the front surface of the upright portion 12. The toilet seat member 20 is rotatably supported by the support portion 13. That is, in the present embodiment, the toilet seat member 20 is rotatably supported with respect to the toilet bowl 90 via the fixing member 10. In addition, the toilet seat member 20 should just be rotatable with respect to the toilet bowl 90, and is not limited to what is connected by the connection method via such a fixing member 10. FIG.

  The toilet seat member 20 includes a toilet seat portion 21 and a storage portion 22 (see FIGS. 1 and 4). The toilet seat 21 is a portion on which a user is seated. The accommodating part 22 provided in the back of the toilet seat part 21 is a part in which various components such as a washing nozzle for washing a local part of the human body and a heater device (control device) for warming washing water are accommodated. The above-described support portion 13 is inserted into the housing portion 22, and the toilet seat member 20 is rotatably supported by the support portion 13. Note that the various components may not be provided. That is, the cleaning function, the heater function, etc. may not be provided. On the side surface of the accommodating portion 22, a rotation shaft portion 23 that protrudes outward in the width direction is provided.

  The toilet lid member 30 is a member that is rotatably supported with respect to the toilet seat member 20. A cylindrical bearing 31 that protrudes inward in the width direction is formed on the inner side of the side surface of the toilet lid member 30 (the side plate 30s that covers the toilet seat member 20 from the outer side in the width direction) (see FIGS. 1 to 6). ). In the bearing portion 31, the rotation shaft portion 23 of the toilet seat member 20 is fitted. That is, the rotation shaft portion 23 is in a state of being rotatably supported by the bearing portion 31. When one of the toilet seat member 20 and the toilet lid member 30 is rotated relative to the other, the rotating shaft portion 23 rotates relative to the bearing portion 31.

  An engaged portion 32 is provided outside the bearing portion 31 of the toilet lid member 30. The engaged portion 32 in the present embodiment is a protrusion that protrudes outward in the radial direction of the bearing portion 31. When the toilet seat member 20 is located at the toilet seat non-use position and the toilet seat member 20 is located at the fully open position, when the toilet seat member 20 is rotated, the engaged portion 32 is associated with the toilet lid member. It is an element constituting a toilet lid maintaining mechanism for maintaining the toilet lid member 30 in the fully open position so that the 30 does not move. When the toilet lid member 30 rotates, the engaged portion 32 moves around the central axis of the bearing portion 31 (rotating shaft portion 23). Since the bearing portion 31 and the engaged portion 32 formed thereon are formed inside the side surface of the toilet lid member 30, when the toilet lid member 30 is attached to the toilet seat member 20, the bearing portion 31 and the engaged portion 32 are visually recognized from the outside. I can't.

  Further, the engaged portion 32 in the present embodiment has a larger amount of protrusion inward in the width direction than other portions (locations where the engaged portion 32 is not formed in the bearing portion 31). Correspondingly, a relief 231 recessed inward in the width direction is formed on the outer side of the rotation shaft portion 23 of the toilet seat member 20 (see FIG. 10). The clearance 231 has a length in the circumferential direction within the rotation range of the toilet lid member 30, and a part on the tip side of the engaged portion 32 (the engaged portion 32 in the bearing portion 31 is formed in the escape 231). It is formed in such a size as to maintain a state in which a portion protruding from a portion that is not formed enters.

  The toilet seat member 20 and the toilet lid member 30 may be capable of being automatically rotated by a drive source, or may be manually rotated. In the case of automatic rotation, the drive source and the like are accommodated in the accommodating portion 22 of the toilet seat member 20.

  The stopper member 40 is a member constituting a toilet lid maintenance mechanism. The stopper member 40 is fixed to a block-like portion (hereinafter referred to as a side portion 14) provided integrally on one side in the width direction of the base portion 11 of the fixing member 10 (see FIG. 7). Located below the bearing 31 of the toilet lid member 30. An engaging portion 41 that is a protrusion protruding upward is formed at the tip of the stopper member 40. The stopper member 40 is biased in a direction in which the engaging portion 41 approaches the bearing portion 31. Specifically, it is as follows. A stopper member support shaft 42 is attached to the fixed member 10. A torsion coil spring 43 is provided outside the stopper member support shaft 42. The stopper member 40 is rotatably supported with respect to the stopper member support shaft 42. One end of the torsion coil spring 43 is fixed to the fixing member 10 or the stopper member support shaft 42, and the other end is fixed to the stopper member 40 (see FIGS. 8 and 9). The stopper member 40 is biased by the torsion coil spring 43 thus fixed so that the engaging portion 41 rotates in a direction approaching the bearing portion 31. In other words, the engaging portion 41 is biased in a direction approaching the engaged portion 32 formed in the bearing portion 31. The engaging portion 41 is positioned below the rotation center axis C of the toilet lid member 30 (horizontal plane passing through the rotation center axis C of the toilet lid member 30) (see FIG. 3).

  In the present embodiment, the outer end portion of the stopper member support shaft 42 has a larger diameter than the other portions (see FIG. 9), and the large diameter portion 421 is hooked to stop the stopper member 40. Is prevented from falling off the stopper member support shaft 42. The end face of the stopper member 40 (end face of the large diameter portion 421) and the end face in the width direction of the stopper member 40 are substantially flush with no step. Therefore, it is excellent in design property. It is also easy to clean.

  The fixing member 10 is provided with a restricting portion 141 that restricts the stopper member 40. The restricting portion 141 in the present embodiment is a protrusion that protrudes outward in the width direction from the side portion 14 of the fixing member 10 (see FIG. 3 and the like). The restricting portion 141 includes a stopper member 40 urged by the torsion coil spring 43 in a direction in which the engaging portion 41 approaches the bearing portion 31 (the engaged portion 32), and the engaging portion 41 is an outer periphery of the bearing portion 31. It fastens in the position which does not contact a surface (part in which the to-be-engaged part 32 is not formed). However, the engaging portion 41 of the stopper member 40 located at this position can contact the engaged portion 32. In other words, the engaging portion 41 is in the turning locus of the engaged portion 32 when the bearing portion 31 is turned.

  In the present embodiment, the restricting portion 141 is in contact with a portion on the distal end side of the stopper member 40 where the engaging portion 41 is provided. That is, since the position regulated by the regulating part 141 is away from the stopper member support shaft 42 that is a fulcrum, the positioning accuracy of the engaging part 41 is high.

  Here, as for the bearing part 31 in this embodiment, some thickness in the circumferential direction is set small compared with another part (refer FIG. 3 etc.). More specifically, a part in the circumferential direction is recessed inward in the radial direction with respect to the other part, and the outer diameter is reduced (hereinafter, this part is referred to as a small diameter part 311). The small-diameter portion 311 is formed in a range facing the engaging portion 41 within a rotation range of the toilet lid member 30 with respect to the toilet seat member 20 (details will be described later).

  Although the operation (operation) of the toilet seat / toilet lid unit 1 having such a configuration partially overlaps with the above description, it will be described in detail below.

  From the state where the toilet lid member 30 covers the toilet bowl 90, that is, the state where the toilet seat member 20 is located at the toilet seat use position and the toilet lid member 30 is located at the fully closed position (the state shown in FIGS. 1 to 3). When 30 is rotated toward the fully open position, the bearing portion 31 formed on the toilet lid member 30 is rotated. That is, the engaged portion 32 formed on the bearing portion 31 rotates. In the present embodiment, when the toilet lid member 30 is located at the fully closed position, the engaged portion 32 is more than the rotation center axis C of the toilet lid member 30 (a plane along the vertical direction passing through the rotation center axis C). It is located rearward (see FIG. 2 and FIG. 3 etc.). When the toilet lid member 30 located at the fully closed position is rotated toward the fully opened position, the engaged portion 32 moves downward. That is, the engaged portion 32 moves in a direction approaching the engaging portion 41 of the stopper member 40. The engaged portion 32 moves in a state where a part of the distal end side enters the relief 231 formed in the toilet seat member 20.

  When the engaged portion 32 moves in this manner, the engaged portion 32 contacts the engaging portion 41 immediately before the toilet lid member 30 reaches the fully open position. In a state before the engaged portion 32 contacts the engaging portion 41 (from when the toilet lid member 30 starts to rotate from the fully closed position until the engaged portion 32 contacts the engaging portion 41), The joint portion 41 faces the small diameter portion 311 of the bearing portion 31, and the engaging portion 41 and the bearing portion 31 are in a non-contact state. That is, the contact between the engaging portion 41 and the bearing portion 31 is prevented by the restriction portion 141 that restricts the position of the stopper member 40 and the small diameter portion 311 provided in the bearing portion 31 (see FIG. 3). Therefore, in this region, the stopper member 40 (engagement portion 41) biased in the direction approaching the bearing portion 31 does not become a member that generates a resistance force that prevents the toilet lid member 30 from rotating. That is, the toilet lid member 30 can be smoothly rotated.

  When the engaged portion 32 comes into contact with the engaging portion 41, the stopper member 40 moves in a direction in which the engaging portion 41 is pushed down against the urging force of the torsion coil spring 43 by the force by which the toilet lid member 30 rotates. Rotate. Further, when the toilet lid member 30 rotates and reaches the fully open position shown in FIG. 4, the engaged portion 32 gets over the engaging portion 41. Accordingly, the stopper member 40 is rotated in the direction in which the engaging portion 41 approaches the bearing portion 31 by the biasing force of the torsion coil spring 43. That is, the engaged portion 32 is caught by the engaging portion 41 (the state shown in FIGS. 5 and 6).

  When the toilet lid member 30 is located at the fully opened position, the engaged portion 32 is caught by the engaging portion 41. Therefore, when the toilet lid member 30 located at the fully opened position is rotated toward the fully closed position. In this case, the engaged portion 32 needs to get over the engaging portion 41. That is, it is necessary to rotate the toilet lid member 30 against the urging force of the torsion coil spring 43 acting on the stopper member 40. Therefore, when the toilet lid member 30 is located at the fully open position, even if the toilet seat member 20 is rotated, the toilet lid member 30 that is rotatably supported with respect to the toilet seat member 20 is rotated. Absent.

  As described above, the toilet seat / toilet lid unit 1 according to the present embodiment rotates the toilet seat member 20 by engaging the engaging portion 41 of the stopper member 40 with the engaged portion 32 of the toilet lid member 30. The toilet lid member 30 located at the fully open position is maintained so as not to move. Since the engaging portion 41 is biased in the direction of engaging with the bearing portion 31, that is, the engaged portion 32, when the engaging portion 41 and the engaged portion 32 are engaged, and the engaging portion When the engagement between 41 and the engaged portion 32 is released, it is possible to suppress an excessive force from acting on the engaging portion 41 and the engaged portion 32 itself. Therefore, the durability of the toilet lid maintenance mechanism for maintaining the toilet lid member 30 in the fully open position is improved as compared with the conventional case (the engagement portion 41 and the engaged portion 32 are prevented from being scraped or damaged). In addition, when the toilet lid member 30 is rotated to engage the engaging portion 41 and the engaged portion 32, or when the engagement of the engaging portion 41 and the engaged portion 32 is released. Further, the resistance force received from the mechanism is reduced, and the operability of the toilet lid member 30 is improved. Moreover, since the engaged part 32 is provided inside the side surface of the toilet lid member 30, the engaged part 32 (a toilet lid maintaining mechanism) is not conspicuous and is excellent in design. Furthermore, cleaning is easy.

  In particular, in the present embodiment, the engaged portion 32 is formed in the bearing portion 31 for rotatably supporting the toilet lid member 30 with respect to the toilet seat member 20. In other words, the engaged portion 32 that is an element constituting the toilet lid maintaining mechanism for maintaining the toilet lid member 30 in the fully opened position is used to rotatably support the toilet lid member 30 with respect to the toilet seat member 20. It is excellent in that it is constructed using the bearing portion 31 as an element. Therefore, it is possible to reduce the elements constituting the toilet lid maintenance mechanism as compared with the conventional case.

  Further, the engaging portion 41 of the stopper member 40 is restricted by the restricting portion 141 so as not to come in contact with a portion other than the portion where the engaged portion 32 is formed in the bearing portion 31. When the joint portion 41 is in contact with the bearing portion 31, the resistance when the toilet lid member 30 is rotated is not increased.

  In particular, in the present embodiment, the portion of the outer peripheral surface of the bearing portion 31 that faces the engaging portion 41 is a small-diameter portion 311 that has a smaller outer diameter than the other portions. The member 40) can be disposed closer to the center of the bearing portion 31, which contributes to the downsizing of the unit (toilet lid maintenance mechanism). The small diameter portion 311 is formed in a portion facing the engaging portion 41 within the rotation range of the toilet lid member 30. In general, the rotation angle of the toilet lid member 30 from the fully closed position to the fully open position is about 90 to 120 degrees, and therefore the angle of the small diameter portion 311 in the bearing portion 31 (a sector shape having the small diameter portion 311 as an arc). The central angle) is about the same. That is, since the small diameter portion 311 formed in the bearing portion 31 is 1/3 or less of the entire circumference (360 degrees), the strength and bearing function of the bearing portion 31 are not significantly reduced. If the strength and bearing function can be secured, the portion functioning as the small diameter portion 311 may be cut out.

  Further, the engaging portion 41 is positioned below the rotation center axis C of the toilet lid member 30, and the engaged portion 32 is rotated by the toilet lid member 30 in a state where the toilet lid member 30 is positioned at the fully closed position. Since it is set to be located behind the central axis C, it is difficult for the user to see the engaging portion 41 and the engaged portion 32. That is, the design of the unit can be improved.

  Further, in the present embodiment, as shown in FIG. 2 and the like, the engaged portion 32 is inward in the width direction compared to other portions (locations where the engaged portion 32 is not formed in the bearing portion 31). The protruding amount of is large. That is, the size in the width direction is large. Therefore, the strength of the engaged portion 32 that repeats engagement / disengagement with the engaging portion 41 is high. When the width of the engaged portion 32 is increased in this way, the size of the unit (toilet lid maintaining mechanism) is increased correspondingly. In this embodiment, a part of the front end side of the engaged portion 32 enters. Since the relief 231 is formed, an increase in the size of the unit due to the increased width of the engaged portion 32 can be suppressed.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment at all, A various change is possible in the range which does not deviate from the summary of this invention.

  For example, in the above-described embodiment, it has been described that the rotation shaft portion 23 is formed on the toilet seat member 20 and the bearing portion 31 that supports the rotation shaft portion 23 is formed on the toilet lid member 30. The part 31 may have a configuration in which the rotation shaft part 23 is formed on the toilet lid member 30. In this case, the engaged portion 32 may be formed outside the rotation shaft portion 23 formed on the toilet lid member 30. That is, a part of the distal end side of the rotation shaft portion 23 enters the bearing portion 31, and the engaged portion 32 is formed at a position where it can engage with the engagement portion 41 on the base side of the rotation shaft portion 23. What is necessary is just to be the structure. Even in this case, the small-diameter portion 311 described above is formed by reducing the outer diameter of the portion facing the engaging portion 41 on the outer peripheral surface of the rotating shaft portion 23 as compared with the other portions. Is possible.

  Moreover, although the said embodiment demonstrated that the bearing part 31, ie, the to-be-engaged part 32, was provided inside the side plate 30s of the toilet lid member 30, the through-hole through which the rotating shaft part 23 passes along the side plate 30s. In addition, the bearing portion 31, that is, the engaged portion 32 may be provided outside the side plate 30s. That is, if the engaged portion 32 is provided on the side surface of the toilet lid member 30, the toilet lid maintenance mechanism is difficult to see from the front of the unit, and the design is excellent. However, if the engaged portion 32 is provided inside the side plate 30s of the toilet lid member 30 as in the above-described embodiment, the side plate 30s functions as a member that covers the engaged portion 32, and thus the toilet lid is maintained. There is an advantage that the mechanism becomes inconspicuous. Alternatively, the side plate 30s may be enlarged so that the stopper member 40 is always covered by the side plate 30s.

  Further, the restricting portion 141 in the above embodiment can be changed as shown in FIG. The restricting portion 141a shown in FIG. 11 is a portion in which a through hole 1411a penetrating in the front-rear direction is formed in the side portion 14 of the fixing member 10. The through hole 1411a is a long hole that is long in the vertical direction. The distal end 40a of the stopper member 40 enters the through hole 1411a. The size in the vertical direction of the tip 40a entering the through hole 1411a is smaller than the size in the vertical direction of the through hole 1411a. That is, the difference in size in the vertical direction, the stopper member 40 can be rotated. When the engaging portion 41 and the engaged portion 32 are not in contact, the tip end 40a of the stopper member 40 comes into contact with the upper edge of the through hole 1411a and its position is regulated. When the engaging portion 41 and the engaged portion 32 come into contact with each other and the engaged portion 32 tries to get over the engaging portion 41, the stopper member 40 is rotated so that the tip 40a thereof passes through the through hole 1411a. It will move downward. Moreover, the front end 40a is regulated in the width direction (the short axis direction of the through hole 1411a) by the side surface along the long axis direction in the through hole 1411a. According to this configuration, the stopper member 40 rattles in the width direction, and the movement can be reduced. Therefore, the movement of the stopper member 40 in the width direction is stabilized, and the operability of the toilet lid member 30 is improved.

  Moreover, the toilet lid maintenance mechanism in the said embodiment is the force for maintaining the toilet lid member 30 in a fully open position when the convex to-be-engaged part 32 will be in the state hooked on the convex-shaped engaging part 41 similarly. However, the shape of the engaging portion 41 and the engaged portion 32 and the engaging structure of both are not limited thereto. When the engaging portion 41 and the engaged portion 32 are engaged, when the toilet lid member 30 located at the fully open position is rotated toward the fully closed position, a certain or more resistance force acts by the engagement. Any configuration may be used. For example, one of the engaging portion 41 and the engaged portion 32 can be a concave portion, and the other can be a convex portion that fits into the concave portion.
