发明名称 Needlepoint supporting frame and clip assembly
摘要 A manually adjustable open four-sided frame and a number of improved clips that cooperate to provide an assembly that removably and frictionally engages a sheet of fabric on which needlepoint or other decoration is being defined to maintain a desired portion of the sheet within the confines of the frame in a taut condition. The clips if desired may be of such structure as to positively as well as frictionally engage peripheral edge portions of the sheet material when the latter is supported in a taut condition on the frame.
