  A large number of conventional tables are provided with a plurality of legs at the bottom of the table to support the table, and the size of the table is usually constant. However, for example, when a table having a narrow top is used as a dining table, there is a situation where the size of the top becomes insufficient when the number of users increases, but the top has a large top in advance. The use of a table causes the problem of bulkiness.

  As a technique for solving such a problem, there exists an example as disclosed by Unexamined-Japanese-Patent No. 2006-346361. Here, as a technique relating to a telescopic table capable of locking a parent table and a child table at any position by a simple operation, a parent table provided with a top plate and legs, and a child top plate smaller than the top plate of the parent table, There is disclosed a structure provided with a child leg portion shorter than a leg portion of a parent table extending downward from a child top plate, the child table being slidably fitted in the longitudinal direction of the parent table, and a parent table and a child table There is disclosed a technology relating to a telescopic table capable of locking and releasing by the operation of a pull placed on a child table.

  According to this technique, although the size of the top of the table can be easily enlarged and reduced, there is a major problem that the top of the parent table and the top of the child table are not flush and steps occur. In addition, there is also a problem that it is necessary to set up a special mechanism for locking the parent table and the child table because the child table has a weight.

  Further, the technology disclosed in JP-A-10-243823 relates to a table having a main top plate and an auxiliary top plate, in which the auxiliary top plate is hinged to one side end of the main top plate, and The pair of crank rods bent in a letter shape can be rocked to a position where only the main top plate is supported on the legs and a position where both the main top and auxiliary top plates are supported on the legs There is disclosed a structure to be attached to. It is suggested that the load applied to the auxiliary top plate can be stably supported by this structure even if the top plate area is expanded.

  According to this technique, although the extended auxiliary top is considered to be stable, there is a problem that only one auxiliary top can be attached. In addition, when the auxiliary top plate is not used, the auxiliary top plate hangs under the main top plate, so that there is a problem that it lacks aesthetics and functionality.

The table is required to be configured to have ease of use and a beautiful appearance as furniture, in addition to the functionality such as the extension of a top plate.
Therefore, the structure is not too complicated, and it is easy to use, and at the time of extension, the top plate and the extension top plate become flush with each other, and when stored, the extension top plate is stored and hidden under the top plate. Development of a stretchable table excellent in design was desired.
