  In a toilet device, a toilet seat and a toilet lid are pivotally attached to the rear of the toilet. Generally, the toilet seat and the toilet lid cannot be easily removed once attached to the toilet. It was. However, for the purpose of improving the cleanability of the toilet seat and the vicinity of the toilet lid, a structure that allows the toilet seat and the toilet lid to be attached and detached may be applied. For example, in Patent Document 1, an engagement member having a substantially U-shaped opening and a lock portion is provided at the base end portion of the toilet seat, and the opening portion is provided on a rotation shaft provided on the toilet body side. An attachment / detachment structure is disclosed in which a toilet lid is rotatably fixed by operating a lock portion in a fitted state.

Japanese Patent No. 4017952

  When the toilet seat and the toilet lid can be attached and detached using a complicated structure like the opening and the lock portion of Patent Document 1, the operation required for attaching and detaching the toilet seat and the toilet lid becomes complicated. In addition, since complicated shaped members are provided on the toilet seat and toilet lid, dust and dirt are likely to collect in the details and gaps of these members, and the attached dust and dirt are difficult to remove. Hygiene of the lid mounting part will be reduced.

  The problem to be solved by the present invention is to provide a toilet apparatus in which a toilet seat and / or a toilet lid are detachably attached by a simple mechanism.

  In order to solve the above-described problems, a toilet apparatus according to the present invention includes an opening / closing member selected from a toilet seat and a toilet lid, and an attachment portion fixed to the rear of the toilet. A support shaft is attached so as to be movable back and forth, and an insertion hole into which the support shaft can be inserted is formed in the opening / closing member, and the support shaft is inserted into the insertion hole with the support shaft advanced. The opening / closing member is pivotally attached to the mounting portion, and the opening / closing member is removed from the mounting portion by retracting the support shaft and removing the support shaft from the insertion hole. And

  Here, the mounting portion has two toilet seat shafts and a toilet lid shaft as the support shaft, the toilet seat has a toilet seat shaft insertion hole, and the toilet seat shaft is inserted into the toilet seat shaft insertion hole. The toilet lid has a toilet lid shaft insertion hole, and is attached to the attachment portion by inserting the toilet lid shaft into the toilet lid shaft insertion hole. When retracted, the toilet seat shaft is preferably retracted in conjunction with the toilet seat shaft, and the toilet seat shaft escapes from the toilet seat shaft insertion hole.

  In this case, the toilet lid shaft and the toilet seat shaft may be connected to each other.

  Further, it is preferable that the support shaft is urged in the forward direction or is fixed at the forward position by a lock mechanism.

  In the toilet device according to the present invention, the support shaft protruding from the mounting portion is inserted into the insertion hole provided in the opening / closing member, so that the opening / closing member is rotatably supported behind the toilet bowl. Since the opening / closing member can be removed from the mounting portion simply by retracting the support shaft and escaping from the insertion hole, the opening / closing member can be easily attached to and detached from the toilet. The mechanism for making the opening / closing member detachable is realized only by a simple configuration of a support shaft that can be moved back and forth and an insertion hole, and specializes in the application of the opening / closing member such as the lock member of Patent Document 1, for example. A member having a complicated shape is not required. Thus, the opening / closing member can be removed from the mounting portion only by a simple operation of pushing the support shaft back into the mounting portion. In addition, only a simple shaft structure and hole structure are formed as members for attaching and detaching the opening and closing member, there are few fine parts where dust and dirt can adhere, even if they adhere, Since it can be easily removed by wiping or the like, hygiene in the vicinity of the attachment portion can be improved.

  Here, the attachment portion has two toilet seat shafts and a toilet lid shaft as support shafts, the toilet seat has a toilet seat shaft insertion hole, and is attached to the attachment portion by inserting the toilet seat shaft into the toilet seat shaft insertion hole. The toilet lid has a toilet lid shaft insertion hole, is attached to the attachment portion by inserting the toilet lid shaft into the toilet lid shaft insertion hole, and when the toilet lid shaft is retracted, the toilet seat shaft is interlocked and retracted, According to the configuration in which the toilet seat shaft escapes from the toilet seat shaft insertion hole, if the toilet lid is removed from the mounting portion to expose the toilet lid shaft, and the toilet lid shaft is pushed back into the mounting portion main body, etc., then automatically The toilet seat shaft is also retracted and escaped from the toilet seat shaft insertion hole provided in the toilet seat. Thereby, the support of the toilet seat by the mounting portion is automatically released. That is, the toilet seat can be easily removed simply by performing an operation of retracting the toilet lid shaft. And since the toilet lid axis | shaft which supports a toilet lid serves also as the operation member for retracting a toilet seat axis | shaft, the structure of an attaching part becomes simple.

  In this case, if the toilet lid shaft and the toilet seat shaft are connected to each other, a configuration in which the toilet seat shaft automatically retracts by retracting the toilet lid shaft can be easily realized.

  In addition, when the support shaft is biased in the forward direction, the support shaft automatically advances when the support shaft is retracted and the opening / closing member is removed. The axis can be easily advanced. Thereby, the attaching / detaching operation of the opening / closing member is further facilitated. In addition, the biasing of the support shaft has an effect that the support of the opening / closing member by the support shaft is stabilized. Even when the support shaft is fixed at the forward movement position by the lock mechanism, the support of the opening / closing member by the support shaft is stabilized.

It is the schematic which shows 1st embodiment of the advance / retreat mechanism of the support shaft in the said attaching part. It is the schematic which shows 2nd embodiment of the advancing / retreating mechanism of the support shaft in the said attaching part. It is the schematic which shows 3rd embodiment of the advancing / retreating mechanism of the support shaft in the said attaching part.

  Hereinafter, a toilet apparatus according to an embodiment of the present invention will be described with reference to the drawings. In this specification, the front, back, and side of the toilet apparatus (and toilet seat) refer to the front, back, and side for the user seated on the toilet seat.

  The toilet device 1 according to the present embodiment is characterized by the structure of the attachment portion 10 for attaching the toilet seat 2 and the toilet lid 3 to the toilet body. FIG. 1 shows a perspective view of the attachment portion 10, and FIG. 2 shows a schematic view of a state in which the toilet seat 2 and the toilet lid 3 are attached using the attachment portion 10.

  The attachment portion 10 is fixed to the toilet body behind the toilet body (not shown), and supports the toilet seat 2 and the toilet lid 3 so as to be rotatable with respect to the toilet. In FIG. 1, the attachment portion 10 is formed integrally with an attachment column 20 that protrudes upward from the rear of the toilet body. In the case where the attachment unit 10 is provided in a toilet apparatus together with a so-called warm water cleaning toilet seat that includes a hot water cleaning device that ejects hot water to the human body part of the user and a hot air drying device that generates hot air, the mounting unit 10 And the attachment pillar 20 may be integrally provided with the main-body part which accommodated the warm water washing | cleaning apparatus and the warm air drying apparatus. The attachment part 10 and the attachment pillar 20 are provided in a pair on the left and right sides of the toilet body.

  Two support shafts, a toilet seat shaft 12 and a toilet lid shaft 13, protrude from the side surface 10a of the mounting portion 10 toward the lateral outer side F. A toilet seat shaft insertion hole 2 a into which the toilet seat shaft 12 can be inserted is formed on both sides of the proximal end portion of the toilet seat 2. By inserting the toilet seat shaft 12 of the mounting portion 10 into the toilet seat shaft insertion holes 2 a on both sides of the toilet seat 2, the toilet seat 2 is rotatably attached to the mounting portion 10. A toilet lid shaft insertion hole 3 a into which the toilet lid shaft 13 can be inserted is formed on both sides of the proximal end portion of the toilet lid 3. By inserting the toilet lid shaft 13 into the toilet lid shaft insertion holes 3 a on both sides of the toilet lid 3, the toilet lid 3 is rotatably attached to the attachment portion 10. In FIG. 2, for easy understanding, the toilet seat shaft insertion hole 2 a and the toilet lid shaft insertion hole 3 a are shown with large diameters with a margin with respect to the toilet seat shaft 12 and the toilet lid shaft 13. The toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a have inner diameters such that the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a rotate in a stable manner in conjunction with the toilet seat shaft 12 and the toilet lid shaft 13. The toilet seat shaft 12 and the toilet lid shaft 13 are press-fitted. A so-called D cut may be formed on the toilet seat shaft 12 and the toilet lid shaft 13 for positioning. In the subsequent drawings, when the shaft-like member is press-fitted into a hole having a shape substantially equal to its outer shape, the hole is shown with a large margin so that it can be easily understood.

  The toilet seat 2 and the toilet lid 3 may be opened and closed manually or automatically opened and closed by power such as a motor. In the case of automatic opening / closing, a rotation mechanism such as a rotor is accommodated inside the mounting portion 10 and connected to the toilet seat shaft 12 and the toilet lid shaft 13.

  The toilet seat shaft 12 and the toilet lid shaft 13 provided in the attachment portion 10 can move forward and backward with respect to the side surface 10 a of the attachment portion 10. In other words, the toilet device 1 can move forward to the lateral outer side F and can move backward to the inner side B. The toilet seat shaft 12 and the toilet lid shaft 13 are inserted into the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a in a state where the toilet seat shaft 12 and the toilet lid shaft 13 are advanced most in the direction F, and as shown in FIG. The lid 3 is attached to the attachment portion 10. On the other hand, the toilet seat shaft 12 and the toilet lid shaft 13 are completely retracted from the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a, respectively, in the state where the toilet seat shaft 12 and the toilet lid shaft 13 are most retracted in the direction B. 3 is not supported by the mounting portion 10. In view of the ease of removing the toilet seat 2 and the toilet lid 3 and the like, when the toilet seat shaft 12 and the toilet lid shaft 13 are completely retracted in the direction B, the entire toilet seat shaft 12 and the toilet lid shaft 13 are attached to the mounting portion 10. It is preferable that the front end surfaces 12a and 13a are flush with the side surface 10a of the mounting portion 10 or enter the inside of the mounting portion 10 rather than the side surface 10a.

  In the state of FIG. 1 in which both the toilet seat shaft 12 and the toilet lid shaft 13 have advanced in the direction F, when the toilet lid shaft 13 is pressed toward the side surface 10a of the mounting portion 10 (arrow A1 in the figure), the toilet seat shaft 12 is In conjunction with the movement of the toilet lid shaft 13, it moves backward in the direction B (arrow A2 in the figure). This enhances the ease of removal of the toilet seat 2.

  The toilet lid 3 is usually made of a material that is more elastically deformed than the toilet seat 2, such as a resin having a small wall thickness. In the state where both the toilet seat 2 and the toilet lid 3 are supported by the mounting portion 10 as shown in FIG. If the toilet lid 3 is elastically deformed so that the portion where the toilet lid shaft insertion hole 3a is formed is pushed outward, the toilet lid shaft insertion hole 3a is removed from the toilet lid shaft 13, and the toilet lid 3 can be easily removed. Can be removed. Then, the toilet lid shaft 13 in a state of being advanced in the direction F is exposed on the side surface 10a of the mounting portion 10. In this state, if the toilet lid shaft 13 is pushed into the side surface 10a side of the mounting portion 10 as indicated by an arrow A1 in FIG. 1, the toilet seat shaft 12 is retracted in the direction B as indicated by an arrow A2 in FIG. The toilet seat shaft insertion hole 2a formed in the toilet seat 2 is escaped. Then, the state in which the toilet seat 2 is supported by the attachment portion 10 via the toilet seat shaft 12 is released. If the toilet seat 2 is lifted, the toilet seat 2 can be completely removed from the upper surface of the toilet. As described above, as long as the toilet lid 3 that is relatively easy to remove is removed, the toilet seat 2 can be removed only by a one-touch operation of pushing the toilet lid shaft 13.

  In order to securely fix the toilet seat 2 and the toilet lid 3 to the toilet seat shaft 12 and the toilet lid shaft 13, respectively, a fixing member such as a screw may be used as an auxiliary. For example, a screw hole is formed in the toilet seat 2 and the toilet lid 3 toward the center of the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a, and a retaining screw is inserted into the screw hole so that the toilet seat shaft 12 and the toilet lid shaft 13 can be brought into contact with each other. In this case, the screw that prevents the toilet seat shaft 12 from coming off may be removed before the toilet lid shaft 13 is pushed in and the toilet seat shaft 12 is retracted.

  Furthermore, it is preferable that the toilet lid shaft 13 and the toilet seat shaft 12 are urged toward the forward direction (direction F) by the urging means incorporated in the attachment portion 10. Then, the toilet lid shaft 13 pushed in to retract the toilet seat shaft 12 and the toilet seat shaft 12 retracted by the operation of the toilet lid shaft 13 are automatically returned to the advanced position. Thereby, in order to attach the toilet lid 3 and the toilet seat 2 to the attaching part 10 again, the operation which pulls out the toilet seat axis | shaft 12 and the toilet lid axis | shaft 13 to the direction F becomes unnecessary, and attachment operation can be performed easily. After the toilet lid shaft 13 is pushed in and the toilet seat shaft 12 is removed from the toilet seat shaft insertion hole 2a, the toilet seat 2 is removed while holding the toilet seat shaft 12 with fingers or the like so that the toilet seat shaft 12 does not immediately advance, If the finger or the like holding the toilet seat shaft 12 is released, the toilet seat shaft 12 and the toilet lid shaft 13 are moved forward, and the toilet seat 2 and the toilet lid 3 can be attached again as they are. Further, since the toilet seat shaft 12 and the toilet lid shaft 13 are biased in the forward direction F, the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole in the state where the toilet seat 2 and the toilet lid 3 are attached to the attachment portion 10 The toilet seat shaft 12 and the toilet lid shaft 13 are prevented from escaping from 3a, and the toilet seat 2 and the toilet lid 3 are stably supported by the mounting portion 10 and rotated.

  As described above, when the toilet seat shaft 12 is retracted by the pushing operation of the toilet lid shaft 13, the toilet seat 2 can be easily detached. In addition, if the toilet seat shaft 12 and the toilet lid shaft 13 are biased in the forward direction F, the toilet seat 2 and the toilet lid 3 can be easily attached. In this way, the toilet seat 2 and the toilet lid are utilized using a simple attachment mechanism in which the two support shafts are exposed to the outside of the attachment portion 10 and the two insertion holes are formed in the toilet seat 2 and the toilet lid 3. 3 can be easily attached and detached. Thus, the attachment / detachment mechanism is configured with a simple configuration, and there is no fine structure or gap in the attachment / detachment mechanism that is likely to accumulate dust and dirt. Even if dust or dirt adheres to the attachment / detachment mechanism, the structure can be easily cleaned by wiping or the like because of its simplicity. Therefore, high hygiene is obtained in the vicinity of the attachment mechanism of the toilet seat 2 and the toilet lid 3.

  Thus, various things can be considered as a specific configuration of the attachment portion 10 in which the toilet lid shaft 13 and the toilet seat shaft 12 are interlocked and the toilet seat shaft 12 is retracted by pushing the toilet lid shaft 13. Examples thereof are shown below.

  The attachment portion 30 according to the first embodiment schematically shown in FIG. 3 includes a block member 31 and a housing member 34. The accommodating member 34 includes a space 34 a that can accommodate the entire block member 31, and the block member 31 is accommodated in the space 34 a of the accommodating member 34. The toilet seat shaft 32 and the toilet lid shaft 33 protrude from the common block member 31. That is, the toilet seat shaft 32 and the toilet lid shaft 33 are connected to each other by the block member 31. A coil spring 35 as an urging means is provided between the inner side surface 34 b of the housing member 34 and the back surface 31 a of the block member 31. The toilet seat shaft 32 and the toilet lid shaft 33 provided integrally with the block member 31 are biased toward the direction F by the coil spring 35, and the state in which the coil spring 35 is in the natural length is the toilet seat shaft 32 and the toilet seat shaft. The lid shaft 33 is moved forward in the direction F most in the movable range.

  When the toilet lid 3 is removed from the attachment portion 30, the toilet lid shaft 33 is exposed. When the toilet lid shaft 33 is pushed in the direction B, the block member 31 and the toilet seat shaft integrated with the toilet lid shaft 33 are provided. 32 moves back in direction B. Then, the toilet seat shaft 32 escapes from the toilet seat shaft insertion hole 2a. At this time, the back surface 31 a of the block member 31 presses the coil spring 35, and the coil spring 35 is compressed between the back surface 31 a of the block member 31 and the inner side surface 34 b of the housing member 34. At this time, since the restoring force of the coil spring 35 acts in a direction to push the block member 31 back in the direction F, the operator presses the toilet lid shaft 33 using fingers or the like, so that the block member 31 is not pushed back. The toilet seat 2 may be prevented from being inserted again into the toilet seat shaft insertion hole 2a by shifting the toilet seat 2 on the toilet. Then, after the toilet seat 2 is completely removed from the toilet seat, for example, by releasing the finger holding the toilet lid shaft 33 or the like, the restoring force of the coil spring 35 causes the toilet seat shaft 32 and the toilet lid shaft 33 to move. Return to the position that protrudes most in the direction F. When the toilet seat 2 and the toilet lid 3 are attached to the mounting portion 30 again, the advanced toilet seat shaft 32 and the toilet lid shaft 33 are connected to the toilet seat shaft insertion hole 2 a of the toilet seat 2 and the toilet lid shaft insertion hole 3 a of the toilet lid 3. Insert it into At this time, if the toilet seat shaft 32 and / or the toilet lid shaft 33 are appropriately pushed and the operation is performed while retracting in the direction B, the mounting operation can be performed without applying excessive deformation to the toilet seat 2 and / or the toilet lid 3. . The attachment portion 30 according to the present embodiment is the same as the second embodiment and the third embodiment described later in that the toilet seat shaft 32 and the toilet lid shaft 33 are formed integrally with the block member 31 and interlocked stably. This is more advantageous than the mounting portions 40 and 50.

  In addition, the side surface 31b of the block member 31 and the side wall surface 34c of the housing member 34 are provided with engagement structures that can be engaged with each other like protrusions and recesses, so that the toilet seat shaft 32 and the toilet lid shaft 33 are retracted in the direction B. If engaged in this state, when the toilet lid shaft 33 is pushed in and the toilet seat shaft 32 is retracted, the toilet seat shaft 32 and the toilet lid shaft 33 are maintained in the retracted state. Therefore, it is not necessary to hold the toilet lid shaft 33 with fingers or the like so that the toilet seat shaft 32 is not pushed back by the coil spring 35, and the toilet seat 2 can be removed more easily. In order to advance the toilet seat shaft 32 and the toilet lid shaft 33 when the toilet seat 2 and the toilet lid 3 are reattached, for example, while the block member 31 is shifted in the space 34a of the housing member 34, the toilet lid shaft 13 By further pushing in, the engagement of the engagement structure may be released. Such an engagement structure can also be applied to the attachment portions 40 and 50 according to the second and third embodiments described below.

  In the mounting portion 30 according to the first embodiment, the toilet seat shaft 32 and the toilet lid shaft 33 are connected and interlocked by the block member 31, but instead of the large block member 31, a thin rod-shaped link member is used. The toilet seat shaft and the toilet lid shaft can be connected to each other via the joint. In the mounting portion 40 according to the second embodiment, the toilet seat shaft 42 and the toilet lid shaft 43 are coupled by a bent rod-shaped link member 44. The combined toilet seat shaft 42 and toilet lid shaft 43 are accommodated in the accommodating member 41. The housing member 41 is formed with a toilet seat shaft housing hole 41 a having an inner diameter substantially equal to the outer diameter of the toilet seat shaft 42 and a toilet lid shaft housing hole 41 b having an inner diameter substantially equal to the outer diameter of the toilet lid shaft 43. A communication hole 41c is formed by communicating the toilet seat shaft accommodation hole 41a and the toilet lid shaft accommodation hole 41b. Of the link member 44, there is a coil spring between a connecting portion 44a extending in a direction substantially orthogonal to the advancing / retreating direction (FB direction) of the toilet seat shaft 42 and the toilet lid shaft 43 and the inner side surface 41d of the communication hole 41c. 45 is arranged.

  Also in this case, as in the case of the attachment portion 30 according to the first embodiment, when the movements of the toilet lid shaft 43 and the toilet seat shaft 42 are interlocked and the toilet lid shaft 43 is pushed in the direction B, the toilet seat shaft 42 is also moved. Retreat in direction B. In addition, the toilet seat shaft 42 and the toilet lid shaft 43 are biased in the forward direction F by the coil spring 55. Of the movable range of the toilet seat shaft 42 and the toilet lid shaft 43, the position advanced most in the direction F is the natural length of the coil spring 55 or the contact between the connecting portion 44a of the link member 44 and the outer surface 41e of the communication hole 41c. It is prescribed by.

  Furthermore, the forward / backward movement of the toilet seat shaft and the toilet lid shaft can be linked with a simpler mechanism that does not use a connecting member such as the block member 31 or the link member 44. In FIG. 5, the attaching part 50 concerning 3rd embodiment is shown. Here, the accommodating member 51 has an inner diameter substantially equal to the outer diameter of the toilet seat shaft 52, has a toilet seat shaft accommodating hole 51 a for accommodating the toilet seat shaft 52, and an inner diameter approximately equal to the outer diameter of the toilet lid shaft 53, A toilet lid shaft accommodation hole 51b for accommodating the toilet lid shaft 53 is formed. The communication hole 51c is formed by communicating the toilet seat shaft accommodation hole 51a and the toilet lid shaft accommodation hole 51b.

  A coil spring 55 is disposed in the communication hole. An end 55 a of the coil spring 55 is coupled and fixed to the rear end surface 52 a of the toilet seat shaft 52. Further, the coil spring 55 is in contact with the rear end surface 53 a of the toilet lid shaft 53. With this configuration, when the toilet lid shaft 53 is pushed in the direction B, the coil spring 55 is pressed against the inner surface 51d of the communication hole 51c by the rear end surface 53a of the toilet lid shaft 53, and the coil spring 55 is compressed, the coil spring 55 is connected. The toilet seat shaft 52 is retracted in the direction B. On the other hand, if the toilet lid shaft 53 is not pressed, the coil spring 55 tries to return to the natural length by the restoring force, the toilet lid shaft 53 moves forward in the direction F, and the toilet seat shaft 52 also has an end portion 55a of the coil spring 55. Is pushed out in the direction F and moves forward.

  In addition to the three embodiments described above, various configurations are conceivable as a specific configuration of the mounting portion 10 in which the toilet seat shaft 12 and the toilet lid shaft 13 can move forward and backward. First, the urging means for urging the toilet seat shaft 12 and the toilet lid shaft 13 in the forward direction F may not necessarily be provided. For example, the mounting portion 30 according to the first embodiment has a configuration without the coil spring 35, and the mounting portion 40 according to the second embodiment has a configuration without the coil spring 45. The thing corresponds to this. In this case, the toilet lid shaft 13 and the toilet seat shaft 12 are automatically moved in the direction F from the state in which the toilet lid shaft 13 is pushed out in the direction B after the toilet lid 3 is removed and the toilet seat shaft 12 is retracted. It will not return to the advanced position. In this case, when the toilet seat 2 and the toilet lid 3 are attached again, the user himself / herself needs to pull out the toilet seat shaft 12 and the toilet lid shaft 13. For example, the toilet seat shaft 12 and the toilet lid shaft 13 may protrude from the side surface 10a of the mounting portion 10 in the state in which the toilet seat shaft 12 and the toilet lid shaft 13 are most retracted in the direction B within the range in which the advancing and retreating is possible. For example, the user can pull out the toilet seat shaft 12 and the toilet lid shaft 13 by pinching the protruding portion with a finger. Alternatively, if an operation portion such as a lever is provided on the toilet seat shaft 12 and the toilet lid shaft 13, the toilet seat shaft 12 and the toilet lid shaft 13 can be easily pulled out by using this operation portion.

  In addition, as described above, the urging means not only advances the toilet seat shaft 12 and the toilet lid shaft 13 in a state where the toilet seat 2 and the toilet lid 3 are removed, and makes it easy to attach the toilet seat 2 and the toilet lid 3 again. In a state where the toilet seat 2 and the toilet lid 3 are attached, the toilet seat shaft 12 and the toilet lid shaft 13 are made difficult to escape from the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a, and the toilet seat 2 and the toilet lid 3 are supported and rotated. Has a role to stabilize. When the urging means is not used, the means for stabilizing the insertion of the toilet seat shaft 12 into the toilet seat shaft insertion hole 2a and the insertion of the toilet lid shaft 13 into the toilet lid shaft insertion hole 3a include: It can be substituted by providing an engagement structure (lock mechanism) between the toilet seat shaft insertion hole 2a and between the toilet lid shaft 13 and the toilet lid shaft insertion hole 3a. That is, the engagement projection is formed on the toilet seat shaft 12 and the toilet lid shaft 13, and when the toilet seat shaft 12 and the toilet lid shaft 13 are completely inserted into the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a, Engagement holes that engage with these engagement protrusions are formed at the edges of the toilet seat shaft insertion hole 2a and the toilet lid shaft insertion hole 3a, and the engagement protrusions are engaged when the toilet seat 2 and the toilet lid 3 are attached. What is necessary is just to engage with a joint hole.

  Furthermore, in the said embodiment, both the toilet seat axis | shaft 12 and the toilet lid axis | shaft 13 were formed so that advancement / retraction was possible, and the backward movement of the toilet seat axis | shaft 12 was driven by the backward movement of the toilet lid axis | shaft 13. That is, the structure of the attachment portion 10 is simply formed by using the toilet lid shaft 13 that is indispensable for rotatably supporting the toilet lid 3 as an operation portion for driving the backward movement of the toilet seat shaft 12. It was. However, the backward movement of the toilet seat shaft 12 for removing the toilet seat 2 does not necessarily have to be driven by the operation of the toilet lid shaft 13 as long as it can be driven by some external force applied from the outside of the mounting portion 10. Good. For example, an operation part such as a lever is coupled to the toilet seat shaft 12, and the user can operate the operation part so that the toilet seat shaft 12 moves forward and backward. In this case, although the structure of the attachment portion 10 is somewhat complicated, it can be preferably applied to the case where the toilet seat 2 can be removed without removing the toilet lid 3.

  Further, as a modified example of the configuration in which the toilet seat shaft 12 is operated by such an operation unit, a configuration in which the toilet lid shaft 13 can also be operated by the operation unit can be given. As shown in each of the above embodiments, when there is no operation unit that can retract the toilet lid shaft 13 by an external force while the toilet lid 3 is attached to the attachment portion 10, the toilet lid shaft 13 remains in the advanced state. While the toilet lid 3 must be removed by utilizing the elastic deformation of the toilet lid 3, etc., if the toilet lid shaft 13 is also retracted by the operation portion in this way, the toilet lid 3 is elastically deformed, etc. Even if it does not make it, it can remove easily.

  In this way, the configuration in which the operation shaft is provided on the support shaft, the support shaft is retracted by applying an external force to the operation portion, and the support shaft is escaped from the insertion hole may be provided on both the toilet lid 3 and the toilet seat 2. You may provide only in either one. When such a configuration is provided in both the toilet lid 3 and the toilet seat 2, the operation portion of the toilet lid shaft 13 may be independent from the operation portion of the toilet seat shaft 12, or may be common. . When the operation parts of the toilet lid shaft 13 and the toilet seat shaft 12 are independent, the necessary one of the toilet seat 2 and the toilet lid 3 can be selectively removed. On the other hand, when the operation parts of the toilet lid shaft 13 and the toilet seat shaft 12 are common, by operating the single operation unit, the toilet seat shaft 12 is escaped from the toilet seat shaft insertion hole 2a, and the toilet lid shaft 13 is operated. Both of the escape from the toilet lid shaft insertion hole 3a can be driven simultaneously, and the toilet seat 2 and the toilet lid 3 can be removed more easily.

  Moreover, the attachment structure of the toilet seat 2 and the toilet lid 3 described above is for the case where the toilet seat 2 and the toilet lid 3 have different attachment shafts. For example, the toilet seat shaft is a hollow toilet lid shaft. Even when both the toilet seat 2 and the toilet lid 3 are pivotally mounted on the same axis as penetrating the toilet seat, the toilet seat shaft and / or the toilet lid shaft are retracted to provide the toilet seat and the toilet seat shaft. It is possible to apply a configuration in which the toilet seat and / or the toilet lid are removed by allowing the shafts to escape from the inserted insertion holes.
