  However, in the conventional toilet seat lift-up device, since the length of the compression coil spring is short, the lift amount of the toilet seat device is small. For this reason, it is difficult to insert a cleaning tool such as a rag into the gap between the toilet seat support member generated by raising the toilet seat device and the rear upper surface of the toilet body, and the rear upper surface of the toilet body is difficult to clean. Therefore, in order to increase the lift amount of the toilet seat device, it is conceivable to use a long compression coil spring having a large extension amount. In this case, the space between the lower end surface of the shaft member and the upper surface of the lid member must be lengthened, or the length of the shaft member must be lengthened. For this reason, the cylindrical member which protrudes below the attachment hole of a toilet bowl main body becomes long. Further, in order to fix the tubular member to the mounting hole, a space for inserting the nut from below the tubular member is also required. For this reason, the vertical length of the space below the tubular member must be increased. However, when the vertical length of the space below the mounting hole of the toilet bowl cannot be increased, or in the existing toilet, the vertical length of the space below the mounting hole of the toilet bowl is short There is. In this case, such a toilet seat lift-up device cannot be used, and the toilet seat device cannot be raised sufficiently.

For this reason, when a toilet seat apparatus raises, it can prevent that a toilet seat apparatus remove | deviates from a toilet bowl main body. Even when the toilet seat device is raised, the shaft member penetrates the tubular member and is held by the tubular member, so that the raised state of the toilet seat device can be stabilized. Furthermore, by raising the shaft member and shortening the length of the shaft member protruding downward from the lower end of the tube member, the vertical length of the space below the tube member can be increased. The nut can be easily screwed from below, and the cylindrical member can be easily attached to the attachment hole.

  A lower end portion of the cylindrical member may be made of a ferromagnetic material, and the locking portion may have a magnetic force. In this case, when the shaft member is raised, the locking portion provided at the lower end portion of the shaft member is magnetically attached to the lower end portion of the cylindrical member. For this reason, the raised state of the toilet seat device can be held not only by the elastic force of the elastic member but also by the magnetic force of the locking portion, and the raised state of the toilet seat device can be stabilized.

  As shown in FIGS. 1 and 2, the toilet seat lift-up device 10 according to the embodiment can attach the toilet seat device 3 to the upper surface of the toilet body 1 so as to be movable up and down. The toilet body 1 has a washing tank 2 placed on the upper surface of the rear end. The toilet seat device 3 includes a toilet seat 4, a toilet lid 5, and a toilet seat support member 6 that pivotally supports the toilet seat 4 and the toilet lid 5. The toilet seat support member 6 incorporates a local cleaning device having a local cleaning nozzle N that can project obliquely forward and downward from the lower surface of the front end.

  As shown in FIGS. 3 and 4, the toilet seat lift-up device 10 includes a shaft member 20, a cylindrical member 30, a compression coil spring 40 that is an elastic member, a cover member 50, an upper plate 60, and a lower plate 70.

  The shaft member 20 is formed to extend coaxially to the first cylindrical portion 20A and the lower end of the first cylindrical portion 20A, and has a second cylindrical portion 20B having a smaller diameter than the first cylindrical portion 20A, and the first cylindrical portion 20A. It is formed from a disc-shaped flange portion 20C that is formed at the upper end and extends outward from the first cylindrical portion 20A. The shaft member 20 has a screw hole formed on the shaft from the upper surface of the flange portion 20C.

  The cylindrical member 30 has a cylindrical shape having a through hole 32 penetrating in the axial direction. The cylindrical member 30 is formed with a thread on the outer peripheral surface, can be inserted with the packing 36, and can be screwed with the nut 35. A square flange 31 is formed at the upper end of the cylindrical member 30. On the upper surface of the flange portion 31, a recess 31A into which the flange portion 20C of the shaft member 20 is fitted is formed. On the lower surface of the collar portion 31, a protruding strip portion 31 </ b> B extending inward from the central portion of each side is formed. The through-hole 32 of the cylindrical member 30 includes a first hole portion 32A that forms an upper portion that is the flange portion 31 side, and a second hole portion 32B that forms a lower portion continuously below the first hole portion 32A. ing. The first hole 32A and the second hole 32B are formed on the same axis. The inner diameter of the first hole 32A is formed larger than the inner diameter of the second hole 32B. The inner diameter of the second hole portion 32B is slightly larger than the outer diameter of the second cylindrical portion 20B of the shaft member 20, and the inner peripheral surface thereof guides the vertical movement of the shaft member 20 in the axial direction. For this reason, the vertical movement of the shaft member 20 in the axial direction can be performed stably. The cylinder member 30 is made of iron.

  The axial length of the shaft member 20 is longer than the axial length of the tubular member 30. For this reason, the shaft member 20 inserted from above into the through hole 32 of the cylindrical member 30 protrudes from the lower end opening of the through hole 32 of the cylindrical member 30. On the lower end surface of the shaft member 20 protruding from the lower end opening of the through hole 32, a ring-shaped magnet 24M and a pair of washers 24W sandwiching the magnet 24M are fixed by bolts B1, and an engaging portion 24 is formed. Yes. The outer diameter of the locking part 24 is formed larger than the inner diameter of the second hole part 32B. For this reason, when the shaft member 20 is raised, the locking portion 24 is locked to the lower surface of the cylindrical member 30 and is magnetically attached by the magnetic force of the magnet 24M.

  The compression coil spring 40 has the shaft member 20 passing through the central shaft portion. The compression coil spring 40 is inserted into the first hole 32 </ b> A of the cylindrical member 30 together with the shaft member 20 from above. The compression coil spring 40 has a top end that is in contact with the lower surface of the flange portion 20C of the shaft member 20, and a lower end that is formed at the boundary between the first hole portion 32A and the second hole portion 32B of the through hole 32 of the cylindrical member 30. In contact with the portion 33, the shaft member 20 is disposed between the outer peripheral surface of the shaft member 20 and the inner peripheral surface of the cylindrical member 30. Thus, the compression coil spring 40 is accommodated in the cylindrical member 30 so as to overlap the shaft member 20. For this reason, even if it does not lengthen the cylindrical member 30, the compression coil spring 40 can be lengthened, and the expansion amount of the compression coil spring 40 can be enlarged. In a state where the compression coil spring 40 is extended, most of the first columnar portion 20A of the shaft member 20 protrudes above the cylindrical member 30.

  The cover member 50 is a cylindrical body, and is formed with a U-shaped claw portion 51 that is engaged with the flange portion 20C of the shaft member 20 in the four directions of the upper end portion. The cover member 50 is connected to the flange portion 20 </ b> C by engaging the claw portion 51 so as to sandwich the outer peripheral edge of the flange portion 20 </ b> C of the shaft member 20. For this reason, the cover member 50 can move up and down in the axial direction together with the shaft member 20. The cover member 50 is inserted from above into the first hole 32A of the cylindrical member 30 while covering the outer periphery of the compression coil spring 40 through which the shaft member 20 has passed. Even when the cover member 50 is lifted together with the shaft member 20 by the elastic force of the compression coil spring 40, the cover member 50 has a length to be inserted into the first hole portion 32 </ b> A of the cylindrical member 30. For this reason, when the compression coil spring 40 expands, the compression coil spring 40 positioned above the cylindrical member 30 is not exposed. Therefore, it is possible to prevent dust and the like from accumulating between the wires forming the compression coil spring 40, and the compression coil spring 40 can be expanded and contracted well over a long period of time.

  The upper plate 60 has an upper surface plate 61 and an upper fixing plate 62. The upper surface plate 61 has a flat plate shape, and insertion pieces 63 extending in the front-rear direction are formed at both left and right ends. A pair of oval recesses 64 extending in the front-rear direction and fitted with washers W are formed inside the left and right insertion pieces 63. A first elongated hole 64H that extends in the front-rear direction and through which the bolt B1 can be inserted is provided in the left and right central portions of the left and right concave portions 64. A pair of first cutout portions 65 is formed inside the recess 64. Each first notch 65 is notched so that a first insertion groove 67A and a locking groove 67B formed in the upper fixing plate 62 described later open upward. A second notch portion 66 opened forward is formed at the center of the upper surface plate 61 that is inside the first notch portion 65. The second notch 66 has a second insertion groove 68 formed in an upper fixing plate 62, which will be described later, opened upward, and a part of a lock member 80 provided in the lower plate 70, which will be described later, is exposed upward. The lock member 80 is cut out so as to be operable from above.

  The left and right width of the upper fixing plate 62 is smaller than the interval between the left and right concave portions 64 formed in the upper surface plate 61. For this reason, when the upper surface plate 61 is fixed to the upper surface of the upper fixing plate 62 with the bolts B <b> 2, the concave portions 64 and the insertion pieces 63 of the upper surface plate 61 are positioned outside the upper left and right ends of the upper fixing plate 62. . A pair of first insertion grooves 67 </ b> A are formed at both left and right ends of the upper fixing plate 62 so as to open forward and upward and extend in the front-rear direction. The right side of each first insertion groove 67A has a rear portion bent diagonally leftward and rearward. The upper fixing plate 62 is formed with a locking groove 67B that extends in the right direction continuously to the rear end portion of each first insertion groove 67A and opens upward. In the center of the front portion of the upper fixing plate 62, a second insertion groove 68 that opens forward, rearward, and upward is formed. An opening 69 penetrating in the vertical direction is formed at the rear of the second insertion groove 68. A flat first locking shelf 81A extending in the horizontal direction is formed on the front side wall forming the opening 69, and a flat second locking shelf 82A extending in the horizontal direction is formed on the rear side wall. Yes. The opening 69 is formed so that a storage portion 75 for storing a lock member 80 provided on a lower fixing plate 71 described later can be inserted from below.

  The upper plate 60 is configured such that the upper surface plate 61 is fixed to the upper surface of the upper fixing plate 62 by bolts B2. A washer W is placed in a pair of recesses 64 formed in the upper surface plate 61, and a bolt B <b> 1 is inserted into the left and right first long holes 64 </ b> H via the washer W from above. The bolt B1 inserted through the first long hole 64H is screwed into a screw hole extending downward from the upper surface of the flange portion 20C of the shaft member 20, and the shaft member 20 is fixed to the lower surface of the upper surface plate 61. The fixed position of the shaft member 20 with respect to the upper plate 60 can be adjusted in the front-rear direction by a first elongated hole 64H extending in the front-rear direction. For this reason, the upper plate 60 can be lowered in an overlapping state with respect to the lower plate 70 described later. As described above, the compression coil spring 40, the cover member 50, the tubular member 30, and the locking portion 24 are assembled to the pair of shaft members 20 fixed to the left and right lower surfaces of the upper plate 60.

  The lower plate 70 includes a lower fixing plate 71 and a lower surface plate 72. The lower fixing plate 71 has a central portion 73 into which the upper fixing plate 62 is fitted, and a groove portion 74 provided on the left and right of the central portion and extending in the front-rear direction. A second elongated hole 74 </ b> H extending in the front-rear direction is provided in the left and right center portion of the bottom surface of the groove portion 74. The left and right width of the groove portion 74 is slightly larger than one piece of the flange portion 31 of the cylindrical member 30, and the left and right width of the second long hole 74 </ b> H is slightly larger than the diameter of the cylindrical member 30. For this reason, when the cylindrical member 30 is inserted into the second long hole 74H, the flange portion 31 of the cylindrical member 30 is locked to the upper surfaces of the left and right edge portions of the second long hole 74H. A plurality of convex portions 74C are arranged at predetermined intervals on the upper surface of the left and right edge portions of the second elongated hole 74H. Since the convex strip portion 31B formed on the lower surface of the flange portion 31 of the cylindrical member 30 is fitted between the convex portions 74C, the lower plate 70 can be prevented from shifting in the front-rear direction with respect to the cylindrical member 30. Two anti-slip packings 77 extending in the front-rear direction are attached to the lower surface of each groove 74.

  A storage portion 75 that stores the lock member 80 is formed in the central portion 73 of the lower fixing plate 71. The lock member 80 has a substantially quadrangular prism shape extending in the left-right direction, and a first recess 83 that opens forward and upward is provided at the center. A second recess 84 that opens upward and to the right is provided on the right side of the right wall portion 83 </ b> R that forms the first recess 83. The second recess 84 houses the compression coil spring 85 with the left end abutting against the right side surface of the right wall 83R. A first locking claw 81B extending in the horizontal direction is formed on the left side of the front surface of the lock member 80, and a second locking claw 82B extending in the horizontal direction is formed on the right side of the rear surface. The upper left surfaces of the first locking claws 81B and the second locking claws 82B are inclined surfaces that are inclined toward the lower left. The storage portion 75 forms a horizontally-long rectangular column-shaped cavity and opens downward. A front opening 76F is formed on the front surface of the storage section 75, and an upper surface opening 76T continuous with the front opening 76F is formed on the upper surface. Further, a rear opening 76 </ b> B is formed on the rear surface of the storage portion 75.

  The lock member 80 is inserted into the storage portion 75 from the lower opening and stored. The lock member 80 is movable in the left-right direction within the storage portion 75 and is urged leftward by the elastic force of the compression coil spring 85. In a state where the lock member 80 is stored in the storage portion 75, the lower surface plate 72 is fixed to the lower surface of the lower fixing plate 71 by the bolt B2. Thereby, the downward opening of the accommodating part 75 is closed. In this state, the first locking claw 81B of the lock member 80 protrudes from the front opening 76F of the storage portion 75, and the second locking claw 82B protrudes from the rear opening 76B. In addition, a part of the left side of the first recess 83 and the second recess 84 is exposed at the upper surface opening 76T.

  When the upper plate 60 is lowered with respect to the lower plate 70, the first locking shelf 81A formed on the upper fixing plate 62 comes into contact with the upper left side of the first locking claw 81B formed on the locking member 82, 82 A of 2nd latching shelf parts contact | abut on the left upper surface of the 2nd latching claw 82B. When the upper plate 60 is further lowered, the first locking shelf 81A and the second locking shelf 82A are lowered along the inclined surfaces of the upper left surfaces of the first locking claw 81B and the second locking claw 82B. Therefore, the lock member 80 moves rightward against the elastic force of the compression coil spring 85. Then, when the upper plate 60 is completely lowered and the upper plate 60 and the lower plate 70 are overlapped, the first locking shelf 81A and the second locking shelf 82A are moved to the first locking claw 81B and It is located below the second locking claw 82B. For this reason, the lock member 80 moves to the left by the elastic force of the compression coil spring 85. Accordingly, the first locking shelf 81A is locked to the first locking claw 81B, and the second locking shelf 82A is locked to the second locking claw 82B. Thus, the upper plate 60 and the lower plate 70 are held in an overlapped state by the first locking shelf 81A, the second locking shelf 82A, the first locking claw 81B, and the second locking claw 82B. A locking mechanism is configured.

  When the lock member 80 is moved in the right direction against the elastic force of the compression coil spring 85 with the upper plate 60 and the lower plate 70 being overlapped, the first locking shelf 81A and the first locking claws 81B Is released, and the engagement between the second engagement shelf 82A and the second engagement claw 82B is also released. Thereby, the upper plate 60 moves upward with respect to the lower plate 70 by the elastic force of the compression coil spring 40 arranged between the outer peripheral surface of the shaft member 20 and the inner peripheral surface of the cylindrical member 30.

  A procedure for attaching the toilet seat device 3 to the upper surface of the toilet body 1 using the toilet seat lift-up device 10 configured as described above will be described.

That is, the first locking shelf 81A is locked to the first locking claw 81B, and the second locking shelf 82A is locked to the second locking claw 82B.

  Next, as shown in FIG. 6, the toilet seat device 3 is attached to the toilet seat lift-up device 10 attached to the rear upper surface of the toilet body 1. On the bottom surface of the toilet seat support member 6 of the toilet body 1, there is provided a recess 9 that can accommodate the upper plate 60 and the lower plate 70 in a superposed state. The concave portion 9 is opened rearward and downward. A pair of insertion grooves 8 that open inward and rearward are formed in the upper edge portions of the left and right ends of the recess 9. The insertion groove 8 can be locked by inserting the insertion piece 63 of the upper plate 60. A lever member 7 is incorporated in the toilet seat support member 6. One end of the lever member 7 is provided with an operation claw 7C bent downward. The outer surface of the operation claw 7 </ b> C is exposed on the side surface of the toilet seat support member 6. The lever member 7 is assembled to the toilet seat support member 6 so as to be slidable in the left-right direction. The lever member 7 is urged to the right by the compression coil spring S1, urged to the left by the compression coil spring S2, and is held at an intermediate position where it can move left and right. The lever member 7 is provided with a pair of locking pieces 7 </ b> A that extend downward and protrude into the recess 9, and a release piece 7 </ b> B. The locking piece 7A is inserted into the first insertion groove 67A of the upper plate 60 and can be locked in the locking groove 67B. The release piece 7 </ b> B is inserted into the second insertion groove 68 of the upper plate 60 and can be inserted into the first recess 83 of the lock member 80 incorporated in the lower plate 70.

  The toilet seat support member 6 having such a configuration is placed on the upper surface of the toilet body 1 on the front side of the toilet seat lift-up device 10, and the upper plate 60 and the lower plate 70 held in an overlapped state by the lock mechanism are recessed. The toilet seat device 3 is slid backward so as to be housed in 9. Then, as shown in FIGS. 7 and 8A, the insertion piece 63 of the upper plate 60 is inserted into the insertion groove 8 formed in the toilet seat support member 6 and locked. Further, the locking piece 7A inserted from the front into the insertion groove 67A of the upper plate 60 is locked to the locking groove 67B. Thereby, the toilet seat apparatus 3 is prevented from moving upward and forward and backward, and the attachment to the toilet body 1 is completed. Thus, the toilet seat device 3 can be easily attached to the toilet seat lift-up device 10 attached to the upper surface of the toilet body 1.

  When the toilet seat device 3 is removed from the toilet body 1, the operation claw 7C of the lever member 7 is pulled out to the left. Thereby, since the locking piece 7A moves leftward, the locking of the locking groove 67B is released, and the toilet seat device 3 can be slid forward. In this way, the toilet seat device 3 can be removed from the toilet body 1. Thus, if the toilet seat support member 6 has the above-described configuration, it can be retrofitted to the toilet body 1 or exchanged via the toilet seat lift-up device 10.

  When the toilet seat device 3 is raised from the upper surface of the toilet body 1, as shown in FIG. 8B, the operation claw 7 </ b> C of the lever member 7 is pushed rightward. As a result, the release piece 7B moves to the right, contacts the right wall 83R of the first recess 83 of the lock member 80, and moves the lock member 80 to the right. Thereby, the locking between the first locking shelf 81A and the first locking claw 81B is released, and the locking between the second locking shelf 82A and the second locking claw 82B is also released. Then, as shown in FIG. 9, the toilet seat device 3 rises from the upper surface of the toilet body 1 by the elastic force of the compression coil spring 40 disposed between the outer peripheral surface of the shaft member 20 and the inner peripheral surface of the cylindrical member 30. . Thus, the lock mechanism can be easily released, and the toilet seat device 3 can be raised.

  In the toilet seat lift-up device 10, the compression coil spring 40 overlaps the shaft member 20 and is accommodated in the tubular member 30, so that the compression coil spring 40 can be lengthened without lengthening the tubular member 30. For this reason, since the extension amount of the compression coil spring 40 can be increased, the rising amount of the toilet seat device 3 can be increased.

  Therefore, in the toilet seat lift-up device 10 of the embodiment, the toilet seat device 3 can be raised sufficiently and the rear upper surface of the toilet body 1 can be easily cleaned.

  Further, when the toilet seat device 3 is raised, the locking portion 24 formed at the lower end of the shaft member 20 is locked to the lower surface of the cylindrical member 30 and is magnetically attached. For this reason, it is possible to prevent the toilet seat device 3 from being detached from the toilet body 1 when the toilet seat device 3 is raised. Further, since the raised state of the toilet seat device 3 can be held not only by the elastic force of the compression coil spring 40 but also by the magnetic force of the magnet 24M of the locking portion 24, the raised state of the toilet seat device 3 can be stabilized. Further, since the inner peripheral surface of the second hole portion 32B of the through hole 32 of the tubular member 30 holds the second columnar portion 20B of the shaft member 20, the raised state of the toilet seat device 3 can be stabilized. Further, since the cover member 50 covers the outer periphery of the compression coil spring 40, dust and the like are prevented from accumulating between the wire members forming the compression coil spring 50, and the toilet seat apparatus can be lifted and lowered satisfactorily.

  Further, in order to lower the raised toilet seat device 3 to the upper surface of the toilet body 1, the toilet seat device 3 is lowered by pressing the upper surface of the toilet seat support member 6. Thereby, the first locking shelf 81A of the locking mechanism can be locked to the first locking claw 81B, and the second locking shelf 82A can be locked to the second locking claw 82B. That is, the upper plate 60 and the lower plate 70 can be held in an overlapped state against the elastic force of the compression coil spring 40, and the toilet seat device 3 is placed on the upper surface of the toilet body 1 for normal use. Can be possible.

  Further, when the toilet seat device 3 moves up and down with respect to the toilet body 1, the inner peripheral surface of the second hole portion 32 </ b> B of the through hole 32 of the tubular member 30 moves up and down in the axial direction of the second cylindrical portion 20 </ b> B of the shaft member 20. Therefore, the toilet seat device 3 can be moved up and down stably.
