Hand grips (16) are fixed to cylindrical sockets (16a) provided with longitudinal tracks (16b). On the frame long sides (B) are a number of stops (11) arranged in a row (D). - In order to select the best position for the hand grips in a longitudinal direction, they are set in a position where the stops can pass through corresp. slots. In a selected interval between two stops, the hand grips are turned to the usage position where they are locked by their stop components. |
