Extendible L-plate for camera equipment

1. A mounting assembly for mounting photographic equipment on a receiving apparatus, said mounting assembly including:

(a) a base member including a portion defining a retention feature engageable and securable by said receiving apparatus, a photographic equipment interface portion and a first engagement portion;

(b) a side member including a portion defining another retention feature engageable and securable by said receiving apparatus and a leg projecting substantially normal to said another retention feature and comprising a second engagement portion slidably engageable with said first engagement portion;

(c) said side member and said leg maintained in a fixed relationship with respect to one another in such a manner that said side member and said leg are free from being readily detachable from one another and being free from being readily movable with respect to one another;

(d) a portion of a peripheral edge portion of said photographic equipment interface portion projecting upward from a longitudinal center of said photographic equipment interface portion to define a shallow receptacle suitable for mounting said photographic equipment where said portion of said peripheral edge is configured such that said portion of said peripheral edge extends upward along a portion of said photographic equipment supported by said photographic equipment interface portion;

(e) said side member defining a lower support and an upper aperture, said lower support being located closer to said leg than said upper aperture, said lower support defining a maximum offset width defined by the distance from a first point on a central axis of said upper aperture at a location defined by said lower support that does not include material comprising said lower support to a first interior periphery edge of said lower support and a maximum offset height along said central axis of said upper aperture, where said first point is further defined as the mid-point of said maximum offset height along said central axis, said upper aperture defining a maximum upper aperture width and a maximum upper aperture height, said maximum lower support offset width is greater than half of said maximum upper aperture width, said maximum lower support offset height is less than said maximum upper aperture height.

2. The mounting assembly of claim 1 further comprising a securing element arranged to releasably secure said sliding engagement of said side member and said base member.

3. The mounting assembly of claim 1 wherein one of said first engagement portion and said second engagement portion comprises plural surfaces defining a dovetail tenon and the other of said first engagement portion and said second engagement portion comprises plural surfaces defining a mortise engageable with said dovetail tenon.

4. The mounting assembly of claim 1 wherein at least one of said retention feature and said another retention feature comprises plural surfaces defining a dovetail tenon.

5. The mounting assembly of claim 1 wherein said portion of said peripheral edge portion is only along one peripheral edge of said side member.

6. The mounting assembly of claim 1 wherein said another retention feature includes discontinuous first and second portions.

7. The mounting assembly of claim 1 wherein said lower support defines at least one of a generally C shaped section and a generally reverse C shaped section.

8. The mounting assembly of claim 7 wherein said at least one of a generally C shaped section and a generally reverse C shaped section includes a vertical side member.

9. The mounting assembly of claim 8 wherein said at least one of a generally C shaped section and a generally reverse C shaped section include a lower horizontal member.

10. The mounting assembly of claim 9 wherein said at least one of a generally C shaped section and a generally reverse C shaped section includes an upper horizontal member.

11. The mounting assembly of claim 10 wherein said upper horizontal member defines a portion of said upper aperture.

12. The mounting assembly of claim 11 wherein said lower horizontal member defines at least a portion of said leg.

13. The mounting assembly of claim 12 wherein said lower support further defines another at least one of a generally C shaped section and a generally reverse C shaped section.

14. The mounting assembly of claim 13 wherein said at least one of a generally C shaped section and a generally reverse C shaped section and said another at least one of a generally C shaped section and a generally reverse C shaped section form a lower aperture.

15. The mounting assembly of claim 1 further comprising said receiving apparatus.

16. The mounting assembly of claim 1 further comprising said photographic equipment.
