发明名称 Book or magazine reading support
摘要 A book or magazine reading support including a rectangular back board with a forwardly extending shelf along the lower margin, and a pair of V-shaped brackets each having a long and a short arm diverging at an acute angle relative to one another. Each bracket has an open slot at the end of each arm. The reading support is optionally assembleable in high or low modes by interconnecting the slots of the long arms or the short arms respectively with the slots of the back board. A thin, clear monofilament line with weights at opposite ends is fastened at the rear of the back board and extends upwardly over the top edge of the back board and downwardly across an opened book or magazine on the front surface of the back board, through a pair of grooves in the shelf. The weights tension the line and hold the pages open.
