Receiving and pick-up device for postal items and corresponding method

1. A receiving and pick-up device for postal items, having a housing comprising a receiving chamber and comprising a base part and an extension part, which is arranged adjustably relative to the base part along an adjustment axis, wherein a closable exterior opening is formed on a first front face of the base part and a closable interior opening is formed on a second front face of the extension part being opposite the first front face in the direction of the adjustment axis, and having an adjustment device, which is designed for adjustment of the volume of the receiving chamber such that the extension part can be adjusted along the adjustment axis between a first position, in which the receiving chamber has a first volume, and a second position, in which the receiving chamber has a second volume enlarged relative to the first volume, and having a deposit band delimiting the receiving chamber at its bottom, wherein the deposit band has a finite length, and the adjustment device has a rotatably mounted winding drum, wherein a first end of the deposit band is connected to the winding drum such that it can be rolled up, and a second end of the deposit band is fixed to a holder spaced apart from the winding drum.

2. The receiving and pick-up device according to claim 1 , wherein the winding drum is held stationary relative to the base part, and the holder is arranged at the extension part, so that the distance between the winding drum and the holder can be reduced by winding the deposit band onto the winding drum.

3. The receiving and pick-up device according to claim 1 , wherein the winding drum can be driven in rotation by a drive motor.

4. The receiving and pick-up device according to claim 1 , wherein the adjustment device has a variable length actuator acting along the adjustment axis, a first longitudinal end of the actuator is held stationary relative to the base part and a second longitudinal end of the actuator is supported by the extension part.

5. The receiving and pick-up device according to claim 1 , wherein the housing is of box-shaped design, the base part and the extension part each having at least two opposing outer walls and each having a cover, so that the housing can be adjusted telescopically along the adjustment axis.

6. The receiving and pick-up device according to claim 1 , wherein an end stop is arranged within the receiving chamber and transversely to the adjustment axis, the end stop being mounted non-rotatably or rotatably to the housing.

7. The receiving and pick-up device according to claim 6 , wherein the rotatably mounted end stop is L-shaped and is connected to the deposit band with a friction-lock such that, when the deposit band is wound onto the winding drum, the end stop is rotated into an upright position, in which a long L-leg of the end stop is set up crosswise to the deposit band.

8. The receiving and pick-up device according to claim 1 , wherein a band reinforcement is arranged below the deposit band, the band reinforcement having at least two movably interconnected reinforcing elements, which are folded or superposed in the first position of the extension part and are pulled apart in the second position of the extension part.

9. The receiving and pick-up device according to claim 1 , wherein supports are provided and designed such that the housing can be supported on a stationary ground.

10. The receiving and pick-up device according to claim 1 , wherein the exterior opening and/or the interior opening each are/is lockable by a roller shutter.

11. The receiving and pick-up device according to claim 1 , wherein the exterior opening and/or the interior opening each are/is lockable by a flap being held pivotably about a pivot axis.

12. The receiving and pick-up device according to claim 11 , wherein the pivot axis is arranged horizontally.

13. The receiving and pick-up device according to claim 11 , wherein a receptacle is provided on the flap closing the exterior opening, the receptacle being arranged on an inner side of the flap facing the receiving chamber.

14. The receiving and pick-up device according to claim 1 , wherein the base part has an installation frame for insertion in an passage opening of a part of a building or an aperture of a stand-alone housing.

15. A method for receiving postal items using the receiving and pick-up device according to claim 1 , comprising the following steps:

providing the receiving and pick-up device, the extension part being arranged in the first position;

identifying a postal item located outside the receiving chamber and located in front of the exterior opening;

actuating the adjustment means to adjust the extension part into the second position in order to adjust the volume of the receiving chamber to the size of the identified postal item;

unlocking the exterior opening after successful identification of the postal item;

checking whether said exterior opening is closed;

unlocking the interior opening only when said exterior opening is closed;

opening said interior opening, and

actuating the adjustment device to adjust the extension part back into the first position.

16. A method for collecting postal items using the receiving and pick-up device according to claim 1 , comprising the following steps:

providing the receiving and pick-up device;

identifying an authorised recipient located in front of the exterior opening;

checking whether the interior opening is closed;

unlocking of the exterior opening after successful identification of the authorized recipient, the exterior opening only being unlocked if the interior opening is closed;

actuating the adjustment device to adjust the extension part into the first position.
