Photographic background assembly

1. A photographic background assembly, the assembly comprising a collapsible background unit having a semi-rigid frame, and a background mounting member, wherein the collapsible background unit comprises a magnetic portion, and wherein the background mounting member comprises at least one magnetic receiving formation configured to engage the magnetic portion of the collapsible background unit, such that the collapsible background unit is selectively attachable to the background mounting member by the magnetic portion so as to provide a background for use in photography, wherein the collapsible background unit comprises a flexible sheet portion, within the semi-rigid frame, which is more flexible than the semi-rigid frame and wherein the flexible sheet portion is formed of an elastic material, which is held in tension by the semi-rigid frame, wherein the photographic background assembly has one or more background mounting members adapted to be selectively attachable to an upper portion of the collapsible background unit, such that the collapsible background unit is suspended from that upper portion when the photographic background assembly is assembled.

2. The photographic background assembly as claimed in claim 1 , wherein the collapsible background unit has the form of a generally planar panel.

3. The photographic background assembly as claimed in claim 1 , wherein the semi-rigid frame has the form of a resilient hoop.

4. The photographic background assembly as claimed in claim 1 , wherein the semi-rigid frame has the form of a resilient band of material, and the collapsible background unit is configured to be collapsed by a user grasping opposite sides of the semi-rigid frame, twisting the semi-rigid frame to form loops, and then folding those loops over, such that the loops lie adjacent to each other, and then repeating where possible.

5. The photographic background assembly as claimed in claim 1 , wherein the magnetic portion of the collapsible background unit is formed by at least one portion of the semi-rigid frame of the collapsible background unit.

6. The photographic background assembly as claimed in claim 5 , wherein the semi-rigid frame is formed of at least one member, at least one of which is formed of a magnetic material.

7. The photographic background assembly as claimed in claim 1 , wherein the magnetic portion of the collapsible background unit has an engagement surface shaped to mate with an engagement surface of the at least one magnetic receiving formation.

8. The photographic background assembly as claimed in claim 1 , wherein the background mounting member forms part of a self-supporting stand, the stand comprising one or more members that are movable relative to each other, being either hingedly or telescopically mounted relative to each other, such that the stand is collapsible.

9. The photographic background assembly as claimed in claim 1 , wherein the background mounting member is disposed in the proximity of an upper end of a self-supporting stand, the at least one magnetic receiving formation of the background mounting member being orientated to receive the magnetic portion of the collapsible background unit from below.

10. The photographic background assembly as claimed in claim 1 , wherein the at least one magnetic receiving formation of the background mounting member comprises one or more permanent magnets.

11. The photographic background assembly as claimed in claim 1 , wherein the background mounting member includes guide surfaces, which guide the magnetic portion of the collapsible background unit into engagement with the at least one magnetic receiving formation of the background mounting member.

12. The photographic background assembly as claimed in claim 1 , wherein the background mounting member includes retaining formations, which resist movement of the collapsible background unit by non-magnetic means, when attached to the background mounting member, in at least one dimension.

13. The photographic background assembly as claimed in claim 1 , wherein the at least one magnetic receiving formation of the background mounting member suspends the collapsible background unit, with retaining formations of the background mounting member resisting lateral movement.

14. The photographic background assembly as claimed in claim 11 , wherein the guide surfaces and/or the retaining formations are formed by at least one housing for the at least one magnetic receiving formation.

15. The photographic background assembly as claimed in claim 11 , wherein the guide surfaces and/or the retaining formations define a channel, with open ends and inclined side surfaces, which receive an elongate magnetic portion of the collapsible background unit.
