<p>The insert, which can be pulled out and down from the top cupboard, is connected to its side walls by two pairs of parallel guide rods which are longer than half the cupboard depth. The link points for the connecting rods on the side walls are set vertically one above the other in the centre plane and in the lower half, whilst the bearing points on the insert are also vertically one above the other in the upper half and in the area of the back wall. The insert may have a supporting frame with a vertical beam extending over its back.</p> |
