## Abstract

The invention relates to a device (100) for providing a crossover point between a first region (1) and a second region (2) hermetically delimited from the first region (1) by means of a wall (10), wherein the device comprises:—a lock chamber (12), which can be inserted into an opening (11) provided in the wall and which has a first opening (13) forming a crossover point between the first region and the lock chamber and which has a second opening (14) forming a crossover point between the second region and the lock chamber;—at least one peripherally circulating element (15), which has at least one passage opening (15.1; 19.1; 15.2; 19.2) and can be moved in relation to the first and the second opening of the lock chamber so that at least a first state, in which the at least one passage opening is substantially aligned with the first opening of the lock chamber and enables access from the first region into the lock chamber and the peripherally circulating element covers the second opening of the lock chamber substantially completely, and a second state, in which the at least one passage opening is substantially aligned with the second opening of the lock chamber and enables access from the second region into the lock chamber and the peripherally circulating element covers the first opening of the lock chamber substantially completely, can be selectively effected.

## Claims

### Claim 1

A device (100) for providing a passage between a first area (1) and a second area (2) which is hermetically delimited from the first area (1) by means of a wall (10), wherein the device (100) comprises the following:
an airlock chamber (12) which can be inserted into an opening (11) provided in the wall (10) which has a first opening (13) forming a passage between the first area (1) and the airlock chamber (12) and which has a second opening (14) forming a passage between the second area (2) and the airlock chamber (12); and
a revolving element (15) configured as one of a conveyor belt and a drum wall for separating the first opening (13) from the second opening (14) having at least one passage opening (15.1; 19.1; 15.2, 19.2), the revolving element movable relative to the first opening and the second opening (13, 14) of the airlock chamber (12) so as to be able to alternatingly realize at least one first state in which the at least one passage opening (15.1; 19; 19.1) is substantially aligned with the first opening (13) of the airlock chamber (12) and allows entry from the first area (1) into the airlock chamber (12) and the revolving element (15) essentially completely covers the second opening (14) of the airlock chamber (12), and a second state in which the at least one passage opening (15.1; 19.1; 15.2, 19.2) or at least a further passage opening (15.1, 19.1, 15.2, 19.2) is substantially aligned with the second opening (14) of the airlock chamber (12) and allows entry from the second area (2) into the airlock chamber (12) and the revolving element (15) essentially completely covers the first opening (13) of the airlock chamber (12);
wherein the revolving element (15) comprises two passage openings (15.1, 15.2) which are arranged in relation to their relative position to one another such that in a state in which a first one of the passage openings (15.1) is aligned with one of the first opening and the second opening (13, 14) of the airlock chamber (12), a second one of the passage openings (15.2) is not aligned with either of the first opening and the second opening (13, 14) of the airlock chamber (12), and in a state in which the second one of the passage openings (15.2) is aligned with one of the first opening and the second opening (13, 14) of the airlock chamber (12), the first one of the passage openings (15.1) is not aligned with either of the first opening and the second opening (13, 14) of the airlock chamber (12).

### Claim 2 (depends on 1)

The device according to claim 1, wherein a drive mechanism is provided to drive the revolving element (15), wherein the drive mechanism comprises at least one horizontally or vertically extending drive element (16.1, 16.2, 16.3, 16.4), wherein the at least one drive element (16.1, 16.2, 16.3, 16.4) is a drive roller.

### Claim 3 (depends on 2)

The device according to claim 2, wherein at least one sealing element (17.1, 17.2) extending in a same direction is allocated to at least one of the at least one drive element (16.1, 16.2) which presses against the at least one of the at least one drive element (16.1, 16.2), wherein the revolving element (15) can be led through a flexible roller gap between the at least one of the at least one drive element (16.1, 16.2) and the at least one sealing element (17.1, 17.2).

### Claim 4 (depends on 1)

A method for an air locked guiding of warehouse stock between a room (2) which is or is able to be rendered inert and an external area (1) by a device according to claim 1, the method comprising steps of:
providing a detector mechanism configured as one of a light barrier or a camera; and
monitoring an interior of the airlock chamber (12) with the detector mechanism, wherein the revolving element (15) is then only movable relative to the openings (13, 14) when the detector mechanism detects a state in which no objects are projecting into a pivoting range of the revolving element (15).

### Claim 5 (depends on 1)

An installation for storing and/or processing objects under inert conditions, wherein the installation comprises the following:
an area (2) enclosed by a spatial shell, wherein at least part of the spatial shell is designed as a wall (10) in which the at least one opening (11) is provided for introducing objects into the enclosed area (2);
a device (100) in accordance with claim 1, wherein the airlock chamber (12) of the device (100) is arranged in the wall opening (11) of the enclosed area (2); and
a device for providing, on an as-needed basis, an inert gas in the form of an oxygen-displacing gas or gas mixture, wherein the device for providing is controllable such that at least a portion of the inert gas provided is conducted into the enclosed area (2) to establish an oxygen-reduced atmosphere in the enclosed area (2).

### Claim 6 (depends on 3)

The device according to claim 3, where the at least one sealing element (17.1, 17.2) includes a sealing roller extending in the same direction.

### Claim 7 (depends on 4)

The method according to claim 4, where the room (2) is a stockroom or warehouse.
