<p>A scaffold structure which includes two or more legs (1, 2) intended for erection to compensate large differences in height on an underlying surface substantially parallel with a work or contact surface, at a distance therefrom. The legs (1, 2) at their upper ends, when erected, are in a known way per se bent inwards or provided with spacers (5, 5') facing towards the work or contact surface in order to produce the said distance. Moreover, the points of impact of the legs (1, 2) against the underlying surface are offset outwards from the work or contact surface relative to the leg portions (4, 4') that are substantially parallel to the work or contact surface. The legs (1, 2) can be connected to a platform (3) at mutually different levels and with varying distances between the legs (1, 2) dependent upon the state of the underlying surface. At the bottom of the middle leg portion (4, 4') there is a safety foot (7) which is capable of being moved downwards telescopically so that it almost touches the ground in order to provide safety in the event of the scaffold sliding out from the wall.</p> |
