said force locking contact with the adjustable part 34 the adjustable part 34 is therefore displaceable and movable in the region of said recess 60 in order that wide variations in the distance between the opposing side parts 2 3 may be bridged and yet the front panel may be connected securely to the side parts by means of the connector 58 it is also important for the recess 61 of fig8 to allow a large adjustment play at right angles to the drawing plane of fig7 fig1 shows a further connection type as it is used for extruded hollow profiles there it is important for the drawer bottom 65 to be connected again pivotably but non detachably to a side part 66 in this embodiment the drawer bottom has a rounded off projection 67 which defines a semi circular recess 68 the side part is shown by the dash dot lines in the swivelled down position 66 39 and if it is swivelled in arrow direction 69 it assumes the position shown by solid lines in terms of shaping the side parts 66 and the drawer bottom 65 consequently take the form of hollow boxes with the drawer bottom 65 having webs on the base for support and forming at the sides with the semi circular projection 67 which forms a recess 68 a hinge in which a hinge pin of the side part 66 further engages said hinge pin 68 of.
