The lower side of the platform (12) of the stand (10) is fitted with three cylindrical elements, each with a bottom in an apex shape. A rectangular insert located at each of the elements has a central slot with a narrow section in the middle and two soft parts at its outer ends. Three screws (22) are guided through bores (24) in the platform (12) into the legs (14,16,18). When the legs (14,16,18) are folded for storage the screws (22) are moved within the slot and the upper ends of the legs (14,16,18) from one of the apex segments to the opposite. |
