Abstract

An arrangement for a monitoring camera device having a camera head being movable within a movement range (MR 1 , MR 2 ) is provided. The arrangement comprises an enclosure for covering the interior of the monitoring camera device and having an opening for the camera head providing a free line of sight for an arbitrary camera head position within the movement range (MR 1 , MR 2 ), a shield movably arranged relative the enclosure for masking parts of the opening not being used for providing the free line of sight for the arbitrary camera head position, the shield comprising a first and a second shield portion mutually movably arranged, wherein the shield is maneuverable between a compressed state and an extended state by movement of the first shield portion relative to the second shield portion. A monitoring camera device comprising the arrangement is further provided.

First claim

What is claimed is:

1. An arrangement for a monitoring camera device having a camera head being movable within a movement range (MR 1 , MR 2 ), the arrangement comprising
an enclosure for covering the interior of the monitoring camera device and having an opening for the camera head providing a free line of sight for an arbitrary camera head position within the movement range (MR 1 , MR 2 ),
a shield movably arranged relative the enclosure for masking parts of the opening not being used for providing the free line of sight for the arbitrary camera head position,
the shield comprising a first and a second shield portion mutually movably arranged, wherein the shield is maneuverable between a compressed state and an extended state by movement of the first shield portion relative to the second shield portion,
the first shield portion of the shield comprises an aperture being moveable in a range corresponding to the movement range (MR 1 ) of the camera head and defined by a first and a second end position by movement of the shield in order to align the aperture with the free line of sight for the arbitrary camera head position,
the shield is maneuverable to the extended state during movement of the aperture from the first end position to the second end position, and
a spring member arranged to cause a relative movement between the first and second shield portion during movement of the aperture from the first end position towards the second end position such that the shield assumes the extended state.

2. The arrangement according to claim 1 , wherein the shield is maneuverable from the compressed state to or towards the extended state in response to an alignment of the aperture of the first shield portion of the shield with the free line of sight for the arbitrary camera head position.

3. The arrangement according to claim 1 , wherein the spring member arranged to cause the relative movement between the first and second shield portion during an initial range part of the movement of the aperture from the first end position to the second end position such that the extended state of the shield is established before the aperture reaches the second end position.

4. The arrangement according to claim 1 , wherein the range defined by the first and the second end position corresponds to a movement range (MR 1 ) of the camera head between 0 and 90 degrees, preferably between 15 and 75 degrees.

5. The arrangement according to claim 1 , wherein the shield is pivotably mounted in the enclosure.

6. The arrangement according to the claim 1 , wherein the shield and/or the enclosure is non-transparent.

7. The arrangement according to claim 1 , wherein the first and the second shield portions overlap in the compressed state of the shield.

8. The arrangement according to claim 7 , wherein the second shield portion comprises a cut out arranged such that the shield in its compressed state forms a continuous outer envelope surface and that a common aperture is defined by the cut out and the aperture of the first shield portion of the shield.

9. The arrangement according to claim 1 , wherein the first and the second shield portions are mutually movably arranged by means of a joint providing a pivotable connection between the first and second shield portions.

10. The arrangement according to claim 9 , wherein the joint comprises a pivot stop defining a maximum pivot angle of the pivotable connection between the first and second shield portions corresponding to the expanded state of the shield.

11. The arrangement according to claim 1 , further comprising a plurality of camera heads each being movable within an associated movement range (MR 1 , MR 2 ), wherein the enclosure further comprises openings for each of the plurality of camera heads such that free lines of sight are provided for each arbitrary camera head position of the associated camera heads within the movement range (MR 1 , MR 2 ) for each of the camera heads, and wherein the first shield portion of the shield comprises a plurality of apertures, each aperture being alignable with the free line of sight for each arbitrary camera head position of the associated camera heads.

12. A monitoring camera device, comprising:
an enclosure for covering the interior of the monitoring camera device and having an opening for the camera head providing a free line of sight for an arbitrary camera head position within the movement range (MR 1 , MR 2 ),
a shield movably arranged relative the enclosure for masking parts of the opening not being used for providing the free line of sight for the arbitrary camera head position,
the shield comprising a first and a second shield portion mutually movably arranged, wherein the shield is maneuverable between a compressed state and an extended state by movement of the first shield portion relative to the second shield portion,
the first shield portion of the shield comprises an aperture being moveable in a range corresponding to the movement range (MR 1 ) of the camera head and defined by a first and a second end position by movement of the shield in order to align the aperture with the free line of sight for the arbitrary camera head position,
the shield is maneuverable to the extended state during movement of the aperture from the first end position to the second end position, and
a spring member arranged to cause a relative movement between the first and second shield portion during movement of the aperture from the first end position towards the second end position such that the shield assumes the extended state.

13. The monitoring camera device according to claim 12 , wherein the shield is maneuverable from the compressed state to or towards the extended state in response to an alignment of the aperture of the first shield portion of the shield with the free line of sight for the arbitrary camera head position.

14. The monitoring camera device according to claim 12 , wherein the first and the second shield portions overlap in the compressed state of the shield.
