The control member 79 carries a pin 206 which is slidably received in a slot 205. A front leg section "OK" of the bed is hinged to an intermediate section 66, for example a peg 109. A front leg 107 is articulated to the bed section 104, for example a peg 108. The upper end of the leg 107 is located

When the bed B is unfolded or raised, the mechanism passes through the positions shown in FIGS. 1, 2, 3 and k. During the first phase of unfolding, in which the bed B is moved from the position according to FIG. 1 to that according to FIG. 2, the main drive lever rotates clockwise about the pivot pin 19, and this movement is supported by the tension of the spring 25 . This has the consequence that the pivot member 17 is rotated about the pivot pin 16 in the clockwise direction. When this happens, the rear swing-out member 37 i "is rotated counterclockwise about the moving pivot pin 36, and this has the result, via the members 48 and 49, that the front and rear intermediate bed sections which are still folded in are moved upwards and forwards so that these sections and the rear leg 68 can pass the front boundary field t 2.

In the second phase of unfolding, the bed B moves from the position according to FIG. 2 to that according to FIG. However, this continued movement has only a relatively small further movement of the swivel member 17 as a result of the continued movement of the lever 2t and the member 37 "da" via the control member 50,; '._ ^l the angular lever 53 and the subsequent actuating member 65 are effective, causes the rear leg to pivot counterclockwise about the. common trunnion 97,

When the bed is in the rolled-out state (Fig. K) , the link 79 is in a horizontal position and is connected to the section 66 via the pivot pin 80 and is prevented from moving to the left is connected to the link 81, this is also prevented from moving to the left. The link 81, since the pin 82 is again connected, holds this pin firmly against movement to the left. The link 63 carries the pin 81, which is located at the left end of the slot: 73 and since it is connected to the head or rear section k3 by means of the pin 6k , it serves to keep this section in a horizontal position. The rear section also has a support on the rear intermediate section kh and holds this rear section in a horizontal position.
