  However, in the toilet seat mounting tool disclosed in Patent Document 1, since the collar portion of the shaft member is merely slid and inserted into the storage portion provided on the bottom surface of the toilet seat support member, the toilet seat device is displaced from the shaft member. There is a risk that. Moreover, in this toilet seat mounting tool, the locking claw and the locking recess are provided below the upper surface of the toilet body, so that the locking claw and the locking recess can be locked or unlocked. When doing so, the locking claw must be operated below the upper surface of the toilet body. For this reason, in this toilet seat fixture, it takes time and effort to raise and lower the toilet seat device.

  On the other hand, in the toilet seat device of Patent Document 2, the toilet seat support member is coupled to the fixed plate in a state where the claw portion is locked in the locking recess, and therefore the toilet seat support member is not easily displaced with respect to the fixed plate. Therefore, it is conceivable that the toilet seat device is lifted and lowered on the upper surface of the toilet body by fixing the fixing plate of the toilet seat device to the upper surface of the toilet body with the toilet seat mounting tool of Patent Document 1. However, even if it does in this way, in order to raise / lower the toilet seat apparatus, the latching nail | claw provided below from the upper surface part of the toilet bowl main body must be operated, and operation takes time. Moreover, the latching nail | claw operated in order to raise / lower a toilet seat apparatus and the operation part operated in order to remove a toilet seat apparatus from the upper surface of a toilet bowl main body will be provided separately. For this reason, it takes time and effort to raise and lower the toilet seat device on the toilet body and to attach and detach the toilet seat device to and from the upper surface of the toilet body.

  The present invention has been made in view of the above-described conventional situation, and includes a toilet seat lift-up device and a lifting toilet seat that can easily lift and lower the toilet seat device on the toilet body and attach / detach the toilet seat device to the toilet body. Providing is a problem to be solved.

The toilet seat lift-up device of the present invention is a toilet seat lift-up device that lifts and lowers a toilet seat device attached to the upper surface of the toilet body,
The toilet seat device is
Toilet seat and
A toilet seat support member for pivotally supporting the toilet seat;
A lever body that reciprocates with the operation portion exposed on the side surface of the toilet seat support member, and extends downward from the lever body portion and projects downward from the lower surface of the toilet seat support member. A lever member having a claw portion that reciprocates between a first position and a second position;
The toilet seat lift-up device is:
A lower plate having a first locking portion and fixed to the upper surface of the toilet body;
An upper opening, a locking recess that is locked by the claw portion moved to the first position, and a second locking portion that is locked to the first locking portion; An upper plate that moves up and down
A toilet seat fixture having a first elastic member for applying an elastic force in the direction of raising the upper plate;
When the operation part is operated and the claw part moves from the first position to the second position, the claw part moves one of the first locking part or the second locking part,
At the intermediate position where the claw portion moves from the first position to the second position, the locked state between the first locking portion and the second locking portion is released, and the claw portion is moved from the intermediate position. When moved toward the second position, the locking state between the claw portion and the locking recess is released.

  In this toilet seat lift-up device, the operation portion is operated in one direction so as to move the claw portion from the first position toward the second position. The locked state with the stop portion can be released. Thereby, the upper plate can be easily raised from the lower plate using the elastic force of the first elastic member of the toilet seat mounting tool. That is, the toilet seat device can be easily raised from the upper surface of the toilet body to the raised position. Furthermore, the latching state of the nail | claw part and a latching recessed part can be cancelled | released by operating an operation part in the same direction and moving a nail | claw part to a 2nd position direction. Thereby, the toilet seat support member can be easily detached from the upper plate. That is, the toilet seat device can be easily detached from the toilet body. Thus, in this toilet seat lift-up device, by operating one operation part in one direction, the toilet seat device can be raised from the upper surface of the toilet body at the intermediate position. Can be removed from the body. Moreover, since the operation part is exposed to the side surface of the toilet seat support member arrange | positioned at the upper surface of the toilet bowl main body, operation can be performed easily.

  Therefore, the toilet seat lift-up device of the present invention can easily lift and lower the toilet seat device on the toilet body and attach / detach the toilet seat device to / from the toilet body.

  Further, the toilet seat lift-up device of the present invention can be used for a toilet seat device provided with a similar lever member. In other words, by attaching this toilet seat lift-up device to the toilet body, if it is a toilet seat device equipped with a similar lever member, for example, even an existing toilet seat device can be lifted and removed from the toilet body. Can be done similarly. Moreover, even if it replaces with a new toilet seat apparatus if the same lever member is provided, the raising / lowering on a toilet bowl main body and attachment / detachment with respect to a toilet bowl main body can be performed similarly. Thus, this toilet seat lift-up device can be applied to a plurality of types of toilet seat devices.

  When the claw portion is moved to the second position by operating the operation portion, the locked state with the locking recess can be released. In this case, the claw portion is in a state of being locked in the locking recess until it moves to the second position, and the locking state between the claw portion and the locking recess is released unless the claw portion is completely moved to the second position. Can not do it. For this reason, when the toilet seat device is removed from the toilet body, the operation unit is operated so that the claw portion is completely moved to the second position. Therefore, the operation of the operation unit for removing the toilet seat device from the toilet body is operated. And the operation of the operation unit for raising the toilet seat device from the upper surface of the toilet body can be clearly distinguished.

  When the claw portion moves from the first position to the second position, the moving direction is opposite to one of the first locking portion and the second locking portion moved by the claw portion. A second elastic member that imparts an elastic force in the direction may be provided. In this case, when operating the operation unit to move the claw portion from the first position to the second position, the elastic force of the second elastic member is applied to prevent the claw portion from moving unintentionally. can do. That is, it is possible to prevent the toilet seat device from being unintentionally raised on the toilet body and removed from the toilet body.

  When the claw portion moves from the intermediate position to the second position, a direction opposite to the moving direction with respect to one of the first locking portion or the second locking portion moved by the claw portion. A third elastic member that imparts an elastic force to can be provided. In this case, compared with the operation of the operation unit for moving the claw part from the first position to the intermediate position, the operation of the operation part for moving the claw part from the intermediate position to the second position is performed by the third elastic member. Since an elastic force is applied, a larger force is required. Thus, since the operational feeling of the operation unit changes, the operation of the operation unit for removing the toilet seat device from the toilet body can be clarified. For this reason, it can prevent removing a toilet seat apparatus from the toilet bowl body unintentionally.

At this time, since the boundary portion between the upper slit 55A and the lower slit 55B can be deformed to the space side of the lower slit 55B, the convex portion 53F can get over the raised portion 55D. Further, since the rising surface of the raised portion 55D on which the convex portion 53F rides is formed in an upward slope, the convex portion 53F can easily get over the raised portion 55D. In this way, as shown in FIG. 10D, the convex portion 53F gets over the raised portion 55D, and the coupled member 55 is attached to the connecting portion 53B. The convex portion 53F that has climbed over the raised portion 55D has a side surface of the raised portion 55D that has been climbed up vertically rising from the bottom surface of the upper slit 55A. It does not rotate backward and come off from the connecting portion 53B.

  As shown in FIGS. 5 to 8, the first compression coil spring 51 is disposed between the second shaft portion 52 </ b> B and the first through hole portion 53 </ b> D, and the lower end surface of the first shaft portion 52 </ b> A and the first through hole portion. It is sandwiched between the lower end surface of 53D. For this reason, the elastic force of the first compression coil spring 51 is applied to the shaft member 52 in the upward direction.

  Since the cylindrical member 53 is formed longer than the second shaft portion 52B, the lower end portion of the first shaft portion 52A is inserted into the upper end portion of the first through hole portion 53D when the shaft member 52 is raised. The lower end portion of the second shaft portion 52B is inserted through the second through-hole portion 53E. Thus, with the shaft member 52 raised, the lower end portion of the first shaft portion 52A is held by the upper end portion of the first through-hole portion 53D, and the lower end portion of the second shaft portion 52B is the second through-hole portion 53E. Is held in. That is, the shaft member 52 can be held at the two most distant positions of the upper end portion and the lower end portion of the cylindrical member 53.

  The first compression coil spring 51 is disposed between the second shaft portion 52B and the first through hole portion 53D, and the outer peripheral surface of the second shaft portion 52B and the inner peripheral surface of the first through hole portion 53D are the first. The expansion and contraction of the compression coil spring 51 is guided. For this reason, even if the 1st compression coil spring 51 is long, it can expand and contract stably.

  Further, the first compression coil spring 51 is always covered with the cylindrical member 53 and is not exposed. For this reason, dust etc. do not collect in the 1st compression coil spring 51, but it can expand and contract stably. Further, since the sound generated when the first compression coil spring 51 is expanded and contracted can be confined in the cylindrical member 53, the noise can be reduced.

  In the lift toilet seat configured as described above, the toilet seat device 10 is attached to the toilet body 1 as shown below.

  First, as shown in FIG. 2, the toilet seat lift-up device 20 is attached to the rear upper surface of the toilet body 1. At this time, when the toilet body 1 is a standard type, the tubular member 53 of the toilet seat mounting tool 50 is inserted into the through hole 44 on the front side of the lower plate 40. Further, when the toilet body 1 is a large type, the tubular member 53 of the toilet seat mounting tool 50 is inserted into the through hole 44 on the rear side of the lower plate 40. Alternatively, the cutout portion 44A of the lower plate 40 may be cut into a long hole, and the tubular member 53 of the toilet seat mounting tool 50 may be inserted into the long hole.

  Next, the cylindrical member 53 is inserted into the mounting hole 2 on the upper surface of the rear part of the toilet body 1 and a nut N is screwed from below to fix the lower plate 40 to the upper surface of the rear part of the toilet body 1. At this time, when the cut portion 44A of the lower plate 40 is cut into a long hole, the lower plate 40 can be fixed to the upper surface of the rear portion of the toilet body 1 while finely adjusting in the front-rear direction.

  Next, the first locking portions 42B and 42C of the lower plate 40 and the second locking portions 32A and 32B of the upper plate 30 are locked, so that the lower plate 40 and the upper plate 30 are overlapped. In this state, the bolt B1 is tightened, the upper plate 30 is sandwiched between the head 52C of the shaft member 52 and the washer W1 through which the bolt B1 is inserted, and the shaft member 52 of the toilet seat mounting tool 50 is fixed to the upper plate 30.

  Next, the toilet seat support member 13 is moved from the front so that the upper plate 30 and the lower plate 40 attached to the rear upper surface of the toilet body 1 are stored in the storage recess 16 provided in the toilet seat support member 13 of the toilet seat device 10. Slide backwards. At this time, the collar portion 30A of the upper plate 30 is slid while being inserted into the groove portion 16A provided in the storage recess 16 of the toilet seat support member 13. Then, the claw portion 14 </ b> C protruding downward from the lower surface of the storage recess 16 of the toilet seat support member 13 is inserted from the front end portion of the locking recess 31 of the upper plate 30. When the claw portion 14C slides the toilet seat support member 13 rearward and the upper plate 30 and the lower plate 40 are completely stored in the storage recess 16, as shown in FIGS. 11 (a) and 12 (a). The first coil is arranged at the first position by the elastic force of the compression coil spring 15. That is, the claw portion 14C is locked to the step portion 31A. In this way, the toilet seat support member 13 is fixed to the upper plate 16. That is, the toilet seat device 10 of the lifting toilet seat is attached to the upper surface of the toilet body 1.

  As shown in FIGS. 11A and 11B and FIGS. 12A and 12B, when the operation unit 14B is pulled out in one direction (left direction) on the lifting toilet seat attached to the toilet body 1, In addition, the claw portion 14C moves from the first position to the second position. Then, the claw portion 14C pushes the convex portion 42D provided on the first locking member 42 of the lower plate 40 in the left direction. For this reason, the first locking member 42 moves to the left against the elastic force of the second compression coil spring 43. Thereby, the 1st latching | locking parts 42B and 42C provided in the 1st latching member 42 also move to the left direction.

  Thus, when operating the operation part 14B to move the claw part 14C from the first position toward the second position, the elastic force of the second compression coil spring 43 is applied, so that the claw part 14C It can prevent moving. That is, it is possible to prevent the toilet seat device 10 from being unintentionally raised on the toilet body 1 or being detached from the toilet body 1.

  At the intermediate position where the claw portion 14C moves from the first position to the second position, as shown in FIGS. 11B and 12B, the first locking portions 42B and 42C are the second locking portions 32A, The locked state with 32B is released. Thereby, the upper plate 30 can be easily raised from the lower plate 40 by using the elastic force of the first compression coil spring 51 of the toilet seat mounting tool 50. That is, the toilet seat device 10 can be easily raised from the upper surface of the toilet body 1 to the raised position.

  Since the elastic force of the first compression coil spring 51 is set to be substantially equal to the load of the toilet seat device 10, the locked state between the first locking portions 42B and 42C and the second locking portions 32A and 32B is only released. Then, the toilet seat apparatus 10 does not rise. However, since the elastic force of the first compression coil spring 51 and the load of the toilet seat device 10 are balanced, the toilet seat device 10 can be lifted without feeling the load of the toilet seat device 10. That is, both sides of the toilet seat support member 13 of the toilet seat device 10 can be held and the toilet seat device 10 can be easily lifted upward while pulling the operation portion 14B leftward and moving the claw portion 14C to the intermediate position.

  When the toilet seat device 10 is lifted and the O-ring 54 at the lower end of the second shaft portion 52B is locked to the locking portion 55E of the coupled member 55 as shown in FIGS. 7 and 8, the toilet seat device 10 is raised. It can be securely held in position. In this state, since the shaft member 52 is held at two positions farthest from the upper end portion and the lower end portion of the tubular member 53, the toilet seat device 10 in the raised position can be stabilized.

  When the toilet seat device 10 is lifted and the O-ring 54 is locked to the locking portion 55E, the coupled member 55 is elastically deformed, so that a click feeling is generated. For this reason, it can recognize that the toilet seat apparatus 10 was hold | maintained in the raise position, and can hold the toilet seat apparatus 10 in the raise position reliably. For this reason, as shown in FIG. 13, even when the toilet seat device 10 is raised, the toilet seat device 10 can be removed from and attached to the upper plate 30 by the following operations.

  When the operation portion 14B is further pulled out to the left and the claw portion 14C is moved to the second position, the claw portion 14C is moved to the locking recess 31 as shown in FIGS. 11 (c) and 12 (c). It moves to a position deviated from the step portion 31A, and the locking state between the claw portion 14C and the locking recess 31 is released. Thereby, the toilet seat support member 13 can be pulled out forward. That is, the toilet seat device 10 can be easily detached from the toilet body 1. Thus, unless the claw portion 14C is completely moved to the second position, the locked state between the claw portion 14C and the locking recess 31 cannot be released. For this reason, when the toilet seat device 10 is removed from the toilet body 1, the operation portion 14B is operated so that the claw portion 14C is completely moved to the second position, and the toilet seat device 10 is removed from the toilet body 1. The operation of the operation unit 14B and the operation of the operation unit 14B for raising the toilet seat device 10 from the upper surface of the toilet body can be clearly distinguished.

  As described above, in this lift toilet seat, by operating one operation portion 14B in one direction (left direction), the toilet seat device 10 can be lifted from the upper surface of the toilet body 1 at an intermediate position, and further operated. The toilet seat device 10 can be detached from the toilet body 1. Moreover, since the operation part 14B is exposed to the left side surface of the toilet seat support member 13 arrange | positioned at the upper surface of the toilet bowl main body 1, operation can be performed easily.

  Therefore, the lifting / lowering toilet seat and toilet seat lift-up device 20 according to the first embodiment can easily lift and lower the toilet seat device 10 on the toilet body 1 and attach / detach the toilet seat device 10 to / from the toilet body 1.

  Further, the toilet seat lift-up device 20 according to the first embodiment can be used for a toilet seat device including the same lever member 14. That is, by attaching the toilet seat lift-up device 20 to the toilet body 1, the toilet seat device having the same lever member 14 can be lifted and lowered on the toilet body 1 even if it is an existing toilet seat device. The attachment / detachment with respect to the toilet body 1 can be performed similarly. Moreover, if the same lever member 14 is provided, even if it replaces with a new toilet seat apparatus, raising / lowering on the toilet body 1 and attachment / detachment with respect to the toilet body 1 can be performed similarly. Thus, this toilet seat lift-up device 20 can be applied to a plurality of types of toilet seat devices.

<Example 2>
As shown in FIG. 14, the elevating toilet seat of the second embodiment is different from the first embodiment in the configuration of the first locking member 142. Other configurations are the same as those of the first embodiment, and the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  The first locking member 142 of the second embodiment includes a moving member 144 that incorporates a third compression coil spring 143 that is a third elastic member and moves in the left-right direction. The main body 142A of the first locking member 142 is provided with a standing wall 145 that is located on the right side of the moving member 144 and moves in the left-right direction together with the main body 142A. As shown in FIG. 14A, the standing wall portion 145 is separated from the right side surface of the moving member 144 when the claw portion 14C is located at the first position. As shown in FIG. 14B, the upright wall portion 145 contacts the right side surface of the moving member 144 when the claw portion 14 </ b> C moves to the left and moves to the intermediate position. When the claw portion 14C moves from the intermediate position to the second position, as shown in FIGS. 14B and 14C, the standing wall portion 145 moves the moving member 144 leftward. At this time, the elastic force of the third compression coil spring 143 is applied to the moving member 144 in a direction opposite to the moving direction (left direction). That is, when the claw portion 14C moves from the intermediate position to the second position, the elastic force of the third compression coil spring 143 is applied to the first locking portions 42B and 42C in the right direction.

  Therefore, the operation of the operation unit 14B for moving the claw part 14C from the intermediate position to the second position is the third operation compared to the operation of the operation part 14B for moving the claw part 14C from the first position to the intermediate position. Since the elastic force of the compression coil spring 143 is applied, a larger force is required. Thus, since the operational feeling of the operation unit 14B changes, the operation of the operation unit 14B for removing the toilet seat device 10 from the toilet body 1 can be clarified. For this reason, it can prevent removing the toilet seat apparatus 10 from the toilet bowl main body 1 unintentionally.
