Shelf system

A shelf system with at least one shelf bottom support, which can be anchored in a shelf rail, so that it projects transversely away from this, wherein a shelf bottom can be laid on the at least one shelf bottom support and detachably fixed to the shelf bottom support, comprising:

• an anchoring cap provided on the shelf bottom support, which can be inserted into a corresponding bore, facing the shelf bottom support, of a shelf bottom in a fixed and preferably captive manner, said anchoring cap having a lower face,
• the anchoring cap has an opening facing the shelf bottom support when lying on the cap lower face, a holding space located behind the opening,
• an access opening, provided in the anchoring cap laterally offset to opening, below which a screw path is formed in the anchoring cap,
• a locking screw that can be twisted in the screw path in the tightening and loosening direction,
• at least one anchoring projection provided on the shelf bottom support facing the shelf bottom,
• for attaching the shelf bottom to the shelf bottom support the anchoring projection penetrates through the opening into the holding space in the anchoring cap,
• the screw path of the locking screw being configured in such a way that the locking screw, adjustable therein, directly or through an intermediate force reversing mechanism and/or force transmission mechanism acts on the anchoring projection of the shelf bottom support and keeps this fixed by tightening or loosening.
