Description

  The present invention relates to a connecting base structural material that can adjust the connection length of the brazing material when the brazing materials or the brazing material and another structural material are coupled to each other.

  For desks and tables used in office spaces such as offices, the height of the top plate support legs made of wood can be adjusted to change the height of the top plate. There are many cases where the length of a desk can be changed by connecting two legs with a connecting rod and adjusting the length of the legs.

As a method of adjusting the length of the top plate support leg, and thus the height of the top plate, the support leg is formed by a hollow outer casing and an inner casing, and an inner casing inserted into the outer casing, There are some which change the connection position with the outer casing (Patent Documents 1 and 2).
However, in the case shown in Patent Document 1, since the brazing material is simply connected by the pressure contact force of the screw, there is a problem in connection strength when a large load is applied, and the connection is accurately performed. It is not easy to determine the appropriate connection length. Moreover, what is shown by patent document 2 requires a complicated process, and there exists a problem in terms of a process man-hour, cost, etc.
