the starting section 90 furthermore takes up approximately 30 of the entire length of the slotted guide track 63 while the transition between the starting section 90 and the slide in section 91 has a curved profile the slide in section 91 runs substantially in a horizontal plane the bearing rollers 65 which are fixed on the housing are disposed approximately level with the slide in section 91 of the slotted guide track 63 the course of movement of the guide carriage 59 of the door 5 in the slotted guide tracks 63 is described with reference to fig9 a to 9c fig9 a shows the door 5 in its closed position in the closed position the sliders 60 of the guide carriage 59 are in the starting section 90 of the slotted guide track 63 during an opening movement of the door 5 from its closed position shown in fig1 the sliders 60 of the guide carriage 59 are initially displaced upward as a result the adjusting levers 67 of the guide carriage 59 lift the door 5 upward with this lifting movement of the door 5 a lower end side 93 of the door 5 which side pivots into the storage space 61 is displaced at the same time upward away from a base 117 of the storage space module 79 as is revealed in fig9 b as a result a pivoting region s of the lower end side 93.
