[0002]

[Prior Art]

 Conventionally, a sink has been composed of a sink having a top and a sink, a sink main body composed of a storage chamber provided under the top, and legs supporting the sink.

An ordinary sink is a square-cylindrical base that cannot be expanded and contracted vertically. However, the floor surface of a kitchen or the like is often an uneven surface instead of a horizontal surface. Therefore, if the sink is installed on this uneven floor, the sink moves easily and is difficult to use. Recently, there is a sink with leg that can be expanded and contracted under the sink to prevent the sink from moving even if it is installed on the uneven floor.

The conventional legs for correcting unevenness, which are attached to the sink body, can expand and contract by at most 2 to 3 cm, and the height of the sink body cannot be adjusted by these legs.

[0005]

[Problems to be solved by the device]

 However, it is easier to use the sink with the top plate up and down. For example, the height of the top plate of an ordinary sink is usually 80 to 85 cm, which is the most convenient height for a young housewife.

However, as the elderly person becomes older, the waist bends, and it becomes difficult to use the tabletop at a conventional height. In addition, the optimum height of the top plate of the sink is different between a tall person and a low person.

Therefore, if the height of the sink can be changed, it is convenient because the same sink can be used by old people and young people, as well as tall people and low people. The present invention has been devised in response to such demands. That is, an object of the present invention is to provide a sink in which the height of the top plate of the sink can be easily changed.
