A shelving system, comprising:
- at least one shelf rail (3) comprising at least one front wall (14) and two side walls (17, 18), which delimit an interior (19) of the shelf rail (3), wherein the front wall (14) includes one or more rows of punched holes (21) for mounting carrier elements (6) at varying heights, wherein the punched holes (21) are disposed along the shelf rail (3) at a distance from one another and create an access to the interior (19);
- a bus bar (22, 22′) configured to supply energy and integrated into the interior (19) of the shelf rail (3) and extending at least in sections along the shelf rail (3), the bus bar comprising:
- a main body (26, 26′) made of an insulating material and comprising a beam (27, 28;
- 107,108) which is associated with and extending substantially parallel to at least one of the two side walls (17, 18) of the at least one shelf rail (3), and
- a first and a second current conductor (23, 24), which extend next to and at a distance from one another along the shelf rail (3) and are insulated from one another;
- at least one bracket (7), which is configured to be detachably hooked into at least one of the punched holes (21) of the shelf rail (3), wherein the bracket (7) comprises at least one engagement section (36, 37) configured to hook the bracket (7) into the shelf rail (3) by being inserted through at least one of the punched holes (21) in the front wall (14) into the interior (19) of the shelf rail (3) to be disposed within the interior (19), and a carrier section (34) for a carrier element (6), wherein the carrier section (34) is configured to protrude from the shelf rail (3) when the bracket (7) is hooked into the shelf rail (3);
- and
- a current collection device (56), which is fastened to the bracket (7) and comprises a housing (61) having a current collection section (64) that is disposed on the engagement section (36, 37) of the bracket (7) and includes tap contacts (66, 67) protruding from the housing (61) for contacting the first and second current conductors (23, 24) of the bus bar (22), and which comprises a connecting section (71) that is disposed on the carrier section (34) of the bracket (7) to connect the tap contacts (66, 67) to a connecting cable (99) of an electrical device (13);
- wherein the tap contacts (66, 67) are configured to be resilient and disposed so as to be pressed into the housing (61) against a spring force when the bracket (7) is being hooked into the shelf rail (3), and to be pressed out of the housing (61) and against the first or second current conductor (23, 24) by the spring force so as to establish an electrically conducting connection when the tap contacts (66, 67) are disposed within the interior (19) behind the front wall (14) after passing one of the punched holes (21).
