Abstract: The bed (10) is provided with a height-adjustable lower frame (14) comprising a plurality of supporting legs (16) and with an upper frame (12) connected with said lower frame. Each supporting leg (16) comprises at its lower end (38) a swivelling and/or guide roller (40) which is received by the supporting leg (16) and is enclosed by a supporting edge (52) of the supporting leg (16) at the lower end (38) of the latter. Said roller (40) is retained by a retaining element (42,44) which is displaceably guided along the supporting leg (16) for the purpose of moving the roller (40) out of the lower end (38) of the supporting leg (16) beyond the supporting edge (52) of the latter and into the lower end (38) of the supporting leg (16). A lifting means (56) is movable out of the upper end (68) of the supporting leg (16) and into the upper end (68) of the supporting leg (16), said lifting means (56) comprising a fastening element (76) which is connected with the upper frame (12).

Abstract: A bed comprises a lower frame (12) having at least one leg or support element (16) for support on a ground and an upper frame (14) connected with the lower frame (12) and having a head element (22) and a foot element (24), as well as at least one connecting element (26) connecting the same. Further, a lying surface (46) having two longitudinal edges (48) extending between the head element (22) and the foot element (24), and at least one safety side element (52; 54) are provided, the at least one safety side element (52; 54) being slidable, beneath the lying surface (46), in a pull-out plane between an insert position and a maximum pull-out position. The at least one safety side element (52; 54) remains extending in the pull-out plane in any intermediate position between insert position and the maximum pull-out position.
