Frame for a drawing board

摘要

A frame for a drawing board consists of a stand and a height-adjustable vertical column on which a drawing board is secured to be pivotable about a horizontal axis. A column brake is used to set the height of the column, and a board brake serves to set the inclination of the board. In order to achieve ease of operation of the frame, both the column brake and the board brake can be actuated from a single actuating member.
