ABSTRACT:
By modification of the design on the U-shaped bracket in previously awarded U.S. Pat. No. 4,628,572, the invention provided a renovated structure for a kind of hinge-typed clipboard which can also equally avoid to use rivets in assembly work. Its elements consist of a board, a supporting base, a clamping element, a torsional spring and a pivotal axle. The distinctive features are that the supporting base is made of metal plate with both sides bent upward and ends rolled up into tube shape. On the board, two transverse groove slots are provided to allow the tube-shaped element of supporting base penetrating through upward from the bottom of the board for combination with clamping element, spring and pivotal axle into an integral clipboard.
