Patent ID: 8918928

Claim:
A bed system comprising a mattress supporting structure ( 1 ) which comprises an outer frame ( 2 ) having a first and a second transverse side ( 5 , 6 ) on opposite transverse sides of the frame and a first and a second longitudinal ( 3 , 4 ) side on opposite longitudinal sides of the outer frame; a plurality of adjacent transverse beams ( 7 ), each of the transverse beams being connected with a first transversal end to the first longitudinal side ( 3 ) of the outer frame ( 2 ) and with a second transversal end to the second longitudinal side ( 4 ) of the outer frame ( 2 ), at least one of said transverse beams being a multi-angular transverse beam ( 7 ) having a plurality of transverse beam sides ( 8 , 9 , 10 , 11 ) and being rotatable about an eccentric rotation axis ( 12 ) which is accessible from outside said outer frame ( 2 ), a plurality of springs ( 13 ) completely movable in a height direction and provided within the outer frame ( 2 ) and mounted on top of the plurality of said transverse beams ( 7 ), and a height adjustment system which comprises said at least one rotatable transverse beam ( 7 ) for completely moving at least one of the springs in a height direction and a rotation imparting connection ( 14 ) comprising a first connector region ( 16 ) engaging the at least one rotatable transverse beam ( 7 ) and a blocking part ( 21 ) cooperating with the outer frame ( 2 ), which connector ( 14 ) is accessible from outside the outer frame along a longitudinal side of the outer frame ( 2 ) and which is provided for imparting a rotation to said at least one rotatable transverse beam ( 7 ) about its eccentric axis ( 12 ), wherein said rotation imparting connector ( 14 ) is displaceable between a first and a second position, said first position being provided for disengaging the blocking part ( 21 ) from cooperating with the outer frame ( 2 ) and rotating said as least one rotatable transverse beam ( 7 ) about its eccentric axis ( 12 ) and said second position being provided by the blocking part ( 21 ) cooperating with the outer frame ( 2 ) for blocking said at least one rotatable transverse beam ( 7 ) in a desired position with respect to said outer frame ( 2 ).
