Abstract:
1. Rack serving device ( 1 ) with a lift carriage ( 3 ) incorporating load-bearing means ( 4 ), whereby the mast ( 2 ) is guided on bottom and top tracks by means of bogie assemblies ( 7 , 8 ) mounted at its mast foot ( 5 ) and mast head ( 6 ), and a displacement mechanism acting by means of a friction lock and displaceable along the bottom guide track serves as a bottom displacement drive ( 13 ) and a displacement mechanism acting by means of a friction lock and displaceable along the top guide track serves as a top displacement drive ( 14 ), the bottom and top displacement mechanisms being guided on the guide tracks by means of height and lateral guide elements ( 20 , 24 ) and displaceable relative to the guide tracks by means of a drive system ( 33 ) with at least one drive roller ( 37 ), and the displacement mechanisms are drivingly connected to the mast ( 2 ), wherein a coupling mechanism ( 29 ) is provided respectively between the guided, displaceable displacement drives ( 13 , 14 ) and bogie assemblies ( 7 , 8 ), comprising at least two coupling parts ( 28 , 40 ) displaceable towards one another perpendicular to the longitudinal extension of the guide track, and at least one coupling connection ( 27 ) extending between the articulation axes ( 42 a , 42 b ) of the coupling parts ( 28 , 40 ), which are mounted so as to pivot about the articulation axes ( 42 a ; 42 b ) substantially perpendicular to the longitudinal extension of the guide track relative to a coupling part ( 28 ; 40 ), and to slide at an end region remote from these articulation axes ( 42 a ; 42 b ) by means of a longitudinal guide ( 44 ) in a direction substantially parallel with the longitudinal extension of the mast ( 2 ).
