摘要： An adjustable frame 1 comprises a pair of primary members 2 held parallel to each other by a pair of secondary members 3 . Each end of each secondary member 3 is slidably engaged with a primary member 2 and the secondary members 3 are pivotally secured to each other at a crossing point 4 . The distance between the primary members 2 may be altered by scissor-like movement of the secondary members 3 . Foot members 5 are pivotally secured to the ends of each primary member 2 . The primary members 2 are provided with pegholes or notches to fixedly locate the secondary members 3 so that a given distance can be maintained between the primary members 2 .
