Storage system and method for storing objects in such a storage system

A storage system comprising:

• at least one shelf having several essentially vertically extending shelf supports set up on a base;
• at least one storage operating vehicle;
• at least two storage aids;
• an operating level arranged at an upper end of the at least one shelf;
• and
• a storage volume arranged below the operating level, wherein the at least one storage operating vehicle is configured to move in the operating level and is configured to introduce the at least two storage aids into the storage volume and to retrieve the at least two storage aids from the storage volume,
• wherein
• each of the storage aids includes an engagement means, and the shelf supports include receiving means arranged in the storage volume,
• wherein the engagement means may be moved between a locking state, in which the engagement means are substantially fixed in at least some of the receiving means and hold the respective storage aid in a storage position in the storage volume, and a release state, in which the engagement means are released from the receiving means,
• wherein the storage operating vehicle is configured to move the engagement means between the locking state and the release state starting from the operating level,
• wherein the storage operating vehicle has a load-receiving means, which may be moved essentially vertically in the storage volume and may be coupled to one of the storage aids for introducing and retrieving the storage aid from the storage volume, and
• wherein the load-receiving means is configured to move the engagement means, in a course of coupling with the storage aid, from the locking state into the release state and/or in a course of decoupling from the storage aid from the release state to the locking state.
