The spring member is arranged between the front surface of the base portion 91 of the stopper 90 and the rear surface within the recessed portion of the slider 50.
When the movable member 3 is located at the lower end position, the protruding piece 92 of the stopper 90 is locked in the lower locking recess 13L of the main body 12 of the fixed plate 10, so that the movable member 3 is located at the lower end position. hold. When the movable member 3 is located at the upper end position, the protruding piece 92 of the stopper 90 is locked in the upper locking recess 13U of the main body 12 of the fixed plate 10, and the movable member 3 is held at the upper end position. Hold.

The spring member of the stopper 90 is such that when the movable member 3 is at the lower end position, when the worker pulls up the mounting body 102 of the Western-style toilet bowl 100, the protruding piece 92 of the stopper 90 engages with the lower locking recess 13L of the fixed plate 10. It has a biasing force that biases the stopper 90 toward the fixed plate 10 so that it comes off from inside.
The spring member of the stopper 90 is configured so that the protruding piece 92 of the stopper 90 prevents the movable member 3 from moving downward due to the weight of the mounting body 102 of the Western-style toilet bowl 100 or a slight impact from the state where the movable member 3 is at the upper end position. The projecting piece 92 of the stopper 90 is placed in the upper locking recess 13U of the fixing plate 10 when the operator pushes down the mounting body 102 of the Western-style toilet bowl 100. It has a biasing force that biases the stopper 90 toward the fixed plate 10 so that it comes off from the locking recess 13U.

Note that the stopper 90 is not biased by a spring member, but the stopper 90 (the entire stopper 90 or the protruding piece 92 of the stopper 90) is configured to be elastically deformable by a resin material or the like, so that the stopper 90 is not biased by the lower side of the fixed plate 10. It is configured to be locked in the locking recess 13L or upper locking recess 13U, and to fall off from the lower locking recess 13L or upper locking recess 13U of the fixed plate 10 when the movable member 3 moves upward or downward. You can also do that.

As shown in FIG. 7 or FIG. 8, in the lifting device 1 configured in this way, when the movable member 3 is moved upward from the lower end position, when the mounting body 102 of the Western-style toilet bowl 100 is pulled up by the operator, The protruding piece 92 of the stopper 90 of the slider 50 falls out of the lower locking recess 13L of the fixed plate 10, and the held member 70 (roller 71 and pin 72), slider 50, and The movable plate 60 and the like move upward. Then, the protruding piece 92 of the stopper 90 of the slider 50 is locked in the upper locking recess 13U of the fixed plate 10, so that the movable member 3 is positioned at the upper end position.
In addition, when the lifting device 1 moves the movable member 3 downward from the upper end position, when the worker presses down the mounting body 102 of the Western-style toilet bowl 100, the protruding piece 92 of the stopper 90 of the slider 50 moves against the fixed plate 10. It falls out of the upper locking recess 13U, and the clamped member 70 (roller 71 and pin 72), slider 50, movable plate 60, etc. move downward while being clamped by the clamping member 40. Then, the protruding piece 92 of the stopper 90 of the slider 50 is locked in the lower locking recess 13L of the fixed plate 10, and the movable member 3 is positioned at the lower end position.

As described above, since the clamping member 40 is configured such that the interval between the clamping bodies 41 is slightly wider in the left and right direction at the top than at the bottom, the movable member 3 (clamped member 70) moves downward. As the movable member 3 (pinched member 70) moves upward, the force with which the clamping body 41 clamps the clamped member 70 increases. Attenuate. With this configuration, it is possible to have a simple configuration in which the damper effect of the clamping body 41 of the clamping member 40 increases as the movable member 3 moves downward.

As described above, since the clamped member 70 is arranged at the left-right center of the main body 12 of the fixed plate 10 or the left-right center of the slider 50 when viewed from the attachment target side (viewed from the front), the air damper is It is possible to stabilize the movement of the movable member 3 when moving up and down, and to further enhance the damper effect, without increasing the size of the device structure compared to a structure in which the movable member 3 is moved up and down. Moreover, by configuring in this way, the number of parts can be reduced compared to the case where the held members 70 are arranged on the left and right sides (two pieces).

The pair of biasing members 4 are mounted by inserting the lower part of the biasing member 4 into the left and right protrusions 32 of the base 30 and inserting the upper part of the biasing member 4 into the left and right cylindrical parts 51 of the slider 50. When viewed from the object (viewed from the front), they are arranged on the left and right outer sides of the clamping member 40 and the clamped member 70, and urge the slider 50 upward. With this configuration, the upward movement of the movable member 3 can be stabilized while assisting the upward movement of the movable member 3. Furthermore, with this configuration, compared to the case where the upward movement of the movable member 3 is similarly assisted by a single urging member 4, a pair of smaller urging members 4 are used to move the lifting device 1. It can be configured to be thin.

As described above, the shielding part 81 of the cover 80 hides the space below the lifting device 1 when the movable member 3 moves to the lower end position. It is possible to prevent foreign matter from entering the space below the device 1.
In addition, since the shielding part 81 of the cover 80 is disposed within the main body part 12 of the fixed plate 10 when the movable member 3 moves to the upper end position, it is difficult to move up and down when the movable member 3 moves to the upper end position. Work in the space below the device 1 can be done easily.

As described above, when the movable member 3 moves to the upper end position, the shielding part 81 of the cover 80 is located at the part that opens in front of the main body part 12 of the fixed plate 10 (main body part Since the space inside the portion 12 is hidden, foreign matter can be prevented from entering the main body portion 12 of the fixed plate 10 when the movable member 3 is located at the upper end position. Further, from this point, the shielding portion 81 of the cover 80 can prevent the holding member 40 disposed within the main body portion 12 of the fixed plate 10 from being exposed when the movable member 3 is located at the upper end position. For example, it is possible to prevent foreign matter from being pinched by the holding member 40. For example, it is also possible to prevent a person's finger or the like from easily entering the main body portion 12 of the fixed plate 10 when the movable member 3 is located at the upper end position.

As described above, since the clamped member 70 includes the rollers 71 which are clamped by the pair of clamping bodies 41 of the clamping member 40 when the movable member 3 moves up and down, the operation when moving the movable member 3 up and down is controlled. It is possible to realize a configuration that allows smooth operation with a simple configuration.

As described above, since the movable member 3 is provided with the stopper 90 that temporarily holds the state in which it is disposed at the lower end position or the upper end position, the movable member 3 may unintentionally move to the lower end position or the upper end position. It is possible to prevent the movable part of the attachment target from being placed in an unintended vertical position.

Further, as described above, since the fixed plate 10 is provided with the locking recess 13 and the stopper 90 is provided with the protruding piece 92 that is locked in the locking recess 13 of the fixed plate 10, the movable member 3 is at the lower end position or the upper end position. It is possible to realize a configuration that can temporarily maintain the state in which it is placed in a simple configuration.

As described above, the roller 71 of the clamped member 70 is provided with the holding groove 73, and since the clamping body 41 of the clamping member 40 clamps the roller 71 of the clamped member 70 in a state arranged in the holding groove 73, it is movable. When moving the member 3 upward or downward to position the movable member 3 from the lower end position to the upper end position or from the upper end position to the lower end position, the state in which the holding member 40 holds the roller 71 can be reliably maintained.

In addition, in the lifting device 1, by appropriately changing the specifications such as the material and shape of the clamping body 41 of the clamping member 40, the clamping body 41 of the clamping member 40 can be clamped according to the specifications of the Western-style toilet bowl 100 (object to be attached). Power can be adjusted.
For example, if you want to strengthen the clamping force of the clamping body 41 of the clamping member 40 to increase the damper effect when the movable member 3 moves up and down, the clamping body 41 of the clamping member 40 may be made of a harder material. Moreover, the clamping body 41 of the clamping member 40 can also be configured with a larger diameter. For example, if it is desired to increase the clamping force of the clamping bodies 41 of the clamping member 40 as the movable member 3 moves downward from the upper end position, the interval between the clamping bodies 41 of the clamping member 40 should be increased upward. It is configured so that the lower part is narrower than the other. Moreover, the clamping body 41 of the clamping member 40 can be configured in a substantially V-shape, or the clamping body 41 of the clamping member 40 can be configured in a crank shape. In addition, when it is desired to make the damper effect of the clamping body 41 of the clamping member 40 stronger, a configuration including three or more clamping members 40 is used, and when it is desired to weaken the damping effect of the clamping body 41 of the clamping member 40, , a configuration including one holding member 40 is also possible.

As shown in FIG. 9, the pin arrangement hole 63 of the movable plate 60 can also be configured to be long in the vertical direction.
In the elevating device 1 configured as described above, when the movable member 3 is moved upward from the lower end position, even if the movable plate 60 moves upward when the mounting body 102 of the Western-style toilet bowl 100 is pulled up by the operator. The clamped member 70 and the slider 50 do not move upward until the lower end of the pin arrangement hole 63 of the movable plate 60 comes into contact with the roller 71 of the clamped member 70 . Furthermore, when moving the movable member 3 downward from the upper end position, even if the movable plate 60 moves downward when the worker presses down the mounting body 102 of the Western-style toilet bowl 100, the pin arrangement hole of the movable plate 60 The clamped member 70 and the slider 50 do not move downward until the upper end of the clamped member 63 comes into contact with the roller 71 of the clamped member 70 .
With this configuration, when the movable member 3 moves up and down, the clamped member 70 is moved up and down by the length of the pin arrangement hole 63 of the movable plate 60 in the vertical direction. The timing of producing the damper effect can be delayed.
Note that the length of the pin arrangement hole 63 of the movable plate 60 in the vertical direction can be configured to an arbitrary length according to specifications.
