<p>The frame is designed for suspending filling documents on and as an extension of the main patent can take documents of two different sizes. The frame consists of two struts (3 4) which are joined together at the bottom and top ends by lengthwise rails (1 2). The arms (31 32 41 42) of the strust (3 4) can be of unequal length so that the shorter arms of the longer arm point upwards in order to fit A4 size paper or folio size documents on the lengthwise support rails. The struts (3, 4) have ends which project beyond the lengthwise support rails (1, 2) so that the rails are protected from damage.</p> |
