Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a mechanism for raising and lowering a vertically raising/lowering washstand in which a washbowl body is raised and lowered up and down.

[Background technology] Height to the top of the bathroom vanity (distance to the floor)
is 720mm according to JIS standards, but it would be easier to use if the height could be changed depending on the height and purpose of use. In recent years, it has been considered to raise and lower the washbowl of a washstand so that the height of the washbowl can be changed, but in the past, link mechanisms and gas springs were combined to raise and lower the washbowl. It uses a complicated mechanism, and the mechanism for lifting and lowering occupies the area under the washbasin body, making it difficult to install and inspect the piping.Furthermore, it is difficult to inspect and replace the gas spring. It was hot.

[Object of the Invention] The present invention has been made in view of the above points, and the object of the present invention is that the washbasin body does not have a mechanism for raising and lowering it, making it easier to install piping and making it easier to inspect the piping. To provide an up-and-down type washstand which is easy to use, has a compact mechanism for raising and lowering, and can also easily attach and detach a gas spring.

The movable guide tube 8 is fixed to the back of the washbowl body 1, and the lower end of the fixed guide tube 9 is installed on the floor 2, and the gas spring 12 is inserted vertically into the elevating body A. One end of the gas spring 12 is removably attached to a mounting portion 45 that is arranged and installed in the opening at the upper end of the movable guide tube 8, and a top plate 27 that can be attached and detached from above the movable guide tube 8 is provided.
The other end of the gas spring 12 is detachably attached to the lower end of the fixed guide cylinder 9, and an opening 46 for attachment and detachment is provided at the lower end of the fixed guide cylinder 9. By configuring as described above, the drawbacks of the conventional example are solved. In other words, the elevating body A that supports the washbowl body 1 in a vertically movable manner is composed of a cylindrical movable guide tube 8 and a cylindrical fixed guide tube 9, and the fixed side guide tube 9 is connected to the movable guide tube 8. Since the movable guide tube 8 is slidably inserted and fixed to the back of the washbowl body 1, and the lower end of the fixed guide tube 9 is installed on the floor 2, there is no elevating means under the washbowl body 1. The pipe B can be easily installed under the washbasin body 1, and the pipe B can be inspected easily.Moreover, by arranging the gas spring 12 in the vertical direction inside the elevating body A, the gas spring 12 can be housed in the elevating body A (provided with a gas spring outside the elevating body A, extra space will be taken up), making it more compact. One end of the gas spring 12 is removably attached to the gas spring 1 , and the upper part of the movable guide cylinder 8 is covered with a removable top plate 27 .
2 is removably attached to the lower end of the fixed guide tube 9, and an opening 46 for attachment and detachment is provided at the lower end of the fixed guide tube 9, so that the gas spring 12 can be installed inside the elevating body A. If possible, remove the top plate 27, remove one end of the gas spring 12 from the upper end of the movable guide tube 8, remove the other end of the gas spring 12 from the attachment/detachment opening 46 at the lower end of the fixed guide tube 9, and then remove the gas spring 12 from the upper end of the movable guide tube 8.
