On an outer side of the first housing part 61 facing away from the second housing part 64, guide channels 62, 63 are integrally formed.

A guide element 52 fixed to the second swivel arm 5 can be guided in each of these guide channels 62, 63 in such a way that when the tray 10 is in the lowered position when the tray 10 is pulled out into the lower swivel position, the guide element 52 is guided along the straight guide channel 62 and during the Pivoting movement of the pivoting arms 4, 5 is guided along or in the second guide channel 63, which is designed in the shape of a segment of a circle.

A first embodiment of the unlocking device 8 is based on the Figures 3 to 7 described.

As in 3 is shown, in the region of the end of the unlocking device 8 received in the guide adapter 6, a holding web extends vertically downwards, to which an unlocking element 85 is fixed.

The unlocking element 85 is preferably designed as an L-shaped lever that is rotatably arranged on the connecting lever 82 and has a first leg 851 and a second leg 852 aligned at an angle to the first leg 851 .

The locking pin 53 can be pushed out of the locking groove 71 of the locking plate 7 by tilting the unlocking element 85 with the first leg 851 .

As in figure 3 is also shown, the unlocking element 85 is held at the crossing point of the two legs 851, 852 via a rotary joint 853 on the connecting lever 82

In order to position the first leg 851 below the locking pin 53, a web 83 is arranged on the connecting lever 82 and extends at an angle to a section of the connecting lever 82 extending along a side surface of the shelf 10 Lever trained unlocking element 85 is held.

The second leg 852 is coupled to a retaining element 66, which is fixed to the guide adapter 6 in the embodiment variant shown, in such a way that during an unlocking movement of the connecting lever 82, in which the pivot joint 853 is moved linearly, the legs 851, 852 rotate about the pivot joint 853, so that during this rotary movement the first leg 851 engages the locking pin 53, as in figure 7 is clearly visible, from the locking groove 71 pushes out.

It is also conceivable to fix the retaining element 66 on the shelf 10 .

In the embodiment variant shown, the retaining element 66 is designed as a stop, in particular a stop bolt. However, other shapes of the retaining element 66 are also conceivable.

Furthermore, the unlocking device 8 is spring-loaded and held in the locking position. For this is as in 3 is shown, a spring element 84 held on the connecting lever 82 is held on the guide adapter 6 .

The spring force of this spring element 84, designed here as a tension spring, counteracts a movement of the connecting lever 82 out of the locking position.

the Figures 4 and 5 show the in the Figures 2 and 3 shown arrangement in a blocking position of the locking pin 53 in the upper loading and unloading position of the tray 10.

As in particular in figure 5 is clearly visible, the locking pin 53 is here in the locking groove 71 of the locking plate 7 a.

In this position, the first leg 851 of the unlocking element 85 bears against the locking pin 53 from below as a result of the positioning of the actuating element 81 in the switching position S1.

If the shelf 10 is now to be pivoted out of its upper loading and unloading position back into a lower position, the actuating element 81 is pivoted in the extension direction A for this purpose.

In the process, the part of the connecting lever 82 guided along the side surfaces of the tray 10 is displaced in the extension direction A by a first switching amount. This position is in the Figures 6 and 7 shown.

As in 6 is clearly visible, the actuating element 81 designed as a handle is pivoted through an angle from its vertical locking position, the first switching position S1, into a release position, the second switching position S2, which is inclined here at an acute angle. The associated displacement of the connecting lever 82 in the extension direction causes the rotary joint 853 to move linearly with the connecting lever 82 in the extension direction.

The contact of the second leg 852 on the retaining element 66 positioned in front of the connecting lever 82 in the direction of movement leads to a rotation of the unlocking element 85 about the axis of rotation 853, at which the first leg 851 pivots upwards and the locking pin upwards out of the locking groove 71 pushes out.

A second embodiment of the unlocking device 8 is based on the Figures 8 to 12 described.

A tongue 854' extends from the base 853' of the unlocking element 85', preferably parallel to an axis of rotation of the unlocking element 85', through a window 612 in the first housing part 61 into a recess 611 in the first housing part 61, in which the locking pin 53 is guided.

By tilting the unlocking element 85' out of the locking position about a bolt 87 serving as a pivot joint, which is arranged, in particular fastened, in a bolt receptacle 69 of the second housing part 64, into a release position, the locking pin 53 is pushed out of the locking groove 71 of the locking plate 7.

The bolt 87 is, as in figure 8 recognizable, on the base 853 'of the unlocking element 85' in a joint receptacle 856 provided for this purpose' near the first leg 851' rotatably attached. For this purpose, a rotary cap 88 is preferably placed on an end of the bolt 87 facing away from the second housing part 64 and is accommodated in the joint receptacle 856′. As a result, the unlocking element 85 ′ is held in a stationary but rotatable manner on the guide adapter 6 via the bolt 87 serving as a rotary joint.

In order to move the actuating element 81, which is designed as a handle, from the in figure 9 To bring about a rotation of the unlocking element 85' from the first switch position S1 shown in the second switch position S2 to the second switch position S2, a retaining pin 89 is arranged on a free end of the first leg 851' in a retaining pin receptacle 855', which is coupled to the web 83 of the connecting lever 82 in such a way that in the event of an unlocking movement of the connecting lever 82 in the pull-out direction A, the unlocking element 85' is rotated or tilted into its unlocked position about the bolt 87 serving as a rotary joint.

The tilting is accompanied by a lifting of the tongue 854 ′ gripping under the locking pin 53 , so that the locking pin 53 is moved out of the locking groove 71 of the locking plate 7 .

In this embodiment variant, too, the unlocking device 8 is spring-loaded and held in the locking position. For this is as in 8 is shown, a spring element 84 held on the second housing part 64 is held on a retaining bolt 89 arranged on the second leg 852' of the unlocking element 85'.

The spring force of this spring element 84, designed here as a tension spring, counteracts a movement of the unlocking element 85' and thus also of the connecting lever 82 out of the locking position.

In order to limit the pivoting movement of the actuating element 81, as shown in FIGS 2 , 4 , 6 and 8th it can be seen that the connecting lever 82 is held parallel to the pivot axis B of the actuating element 81 with at least one clamp 86 fastened to a web of the shelf 10 .

In the embodiment variants shown here, such a clip 86 is arranged on both sides of the actuating element 81 .
