  • Patent number: 5187821
    Abstract: In a hospital bed comprising a body (4) provided with wheels, a transfer underlay frame (24) for a patient, a lying or resting frame (17), which can be lifted and lowered down, lifting means (30) for the lying frame, and bearer means (15, 20) for a transfer underlay frame; the bearer means comprise two U-shaped bearer rods (15) disposed side by side and turnable in the body, the upper and the lower arms (15b, 15c) of which are interconnected through articulated joints (18, 22) by a transverse support (16, 21) so as to secure a parallel turn of the arms aside. A bearer beam (20) is secured to the upper transverse support (21) and wheels (19) to the lower support (16). The invention allows a sideways transfer of a patient on a transfer underlay supported by straps (26, 28) secured to a bearer beam, without changing the direction. Wheels (19) provided in the bearer rods (15) move simultaneously to the same direction which ensures that the bed (2) is properly supported during all stages of the transfer.
