Rail system for a conveying vehicle and storage system

A rail system (20a;

• 20b) for a conveyor vehicle (4) capable of traveling along the rail system (20a;
• 20b) for storage of piece goods (5) into a storage rack (2) or retrieval of piece goods (5) from a storage rack (2), comprising
• a first running rail (33a;
• 55a),
• a second running rail (33b;
• 55b),
• a connecting device (34;
• 56;
• 62), which comprises a positive locking connection between the axial ends (35a, 35b;
• 59a, 59b) of the first running rail (33a;
• 55a) and the second running rail (33b;
• 55b) that are directed towards one another,
• at least one guide track (23;
• 25;
• 27) along the first running rail (33a;
• 55a) and second running rail (33b;
• 55b), on which a running wheel (22, 24a, 24b, 26a, 26b, 28) of a chassis (16a, 16b) of the conveyor vehicle (4) bears in rolling relationship, wherein
• the first running rail (35a;
• 55a) forms a first interlocking element (36a) and a first surface portion (37a) at the end (35a;
• 59a) thereof,
• the second running rail (33b;
• 55b) forms a second interlocking element (36b) and a second surface portion (37b) at the end (35b;
• 59b) thereof,
• wherein the first interlocking element (36a) and second interlocking element (36b) engage in one another in complementary manner,
• and wherein
• the first surface portion (37a) extends in a cross-sectional plane perpendicular to the first running rail (33a;
• 55a) and the second surface portion (37b) extends in a cross-sectional plane perpendicular to the second running rail (33b;
• 55b), and the first surface portion (37a) and the second surface portion (37b) adjoin the at least one guide track (23;
• 25;
• 27), and
• wherein
• the first interlocking element (36a) is formed in one piece at the end (35a;
• 59a) of the first running rail (33a;
• 55a) and by at least one positioning opening (38), which is disposed in recessed manner in the end (35a;
• 59a) and which extends with a depth parallel to a longitudinal axis of the first running rail (33a;
• 55a), and
• the second interlocking element (36b) is formed in one piece at the end (35b;
• 59b) of the second running rail (33b;
• 55b) and by at least one positioning projection (39), which protrudes perpendicularly at the end (35b;
• 59b) and which extends with a length parallel to a longitudinal axis of the second running rail (33b;
• 55b), and wherein
• the first running rail (33a;
• 55a) and the second running rail (33b;
• 55b) are equipped with a guide track (27), extending in longitudinal direction of the rail system (20a;
• 20b), for a running wheel (22, 28) of the conveyor vehicle (4), wherein at least one of the interlocking elements (36a, 36b) adjoins the guide track (27) and forms a sub-portion of the guide track (27),
• and the axial ends (35a, 35b;
• 59a, 59b) of the first running rail (33a;
• 55a) and second running rail (33b;
• 55b) abut at the surface portions (37a, 37b) in a butt-jointed manner, so that an almost gap-free transition to the at least one guide track (23;
• 25;
• 27) is formed between the first running rail (33a;
• 55a) and second running rail (33b;
• 55b).
