Japanese Patent JP4628480
Kind Code:

Abstract:
A desk leaf base includes a base and a binder. The base is formed of a trapezoidal tubular body that is formed in a trapezoidal shape in a side view, closed from a bottom surface to a certain height in both sides, and opened in an upper portion therefrom. An inclined front wall of the tubular body is removed from one side to the other side, in a range from the certain height to a height higher than the certain height and lower than a top surface. The binder is mounted along an elongated top surface of the base, and includes an elongated body and a plurality of rings. The elongated body is mounted along the top surface of the base with an approximately same width as the top surface. The plurality of rings are mounted on the body and capable of opening and closing. Each of the plurality of rings includes linear portions that protrude from the body so as to extend inclining upward on front and back sides when closing. Accordingly, the desk leaf base which allows the leaf group to easily be replaced is achieved.
