Abstract

A ball head based lever clamping device.

First claim

What is claimed is:

1. An apparatus for selectively engaging a plate for photographic equipment and a rail assembly for a firearm, said apparatus comprising:
(a) a body and an arm capable of lateral movement collectively defining an upper channel having a pair of sidewalls suitable to detachable engage a pair of angled edges of said plate;
(b) said body and said arm capable of lateral movement collectively defining a lower channel having a pair of sidewalls suitable to detachably engage a rail of said rail assembly;
(c) said body defining an upper body and defining an upper cavity, said body defining a lower body and defining a lower cavity;
(d) a base that includes a ball that is sized to be rotatably maintained within a cavity defined by said upper cavity and said lower cavity;
(e) said upper body and said lower body capable of vertical movement to selectively inhibit movement of said body with respect to said ball.

2. The apparatus of claim 1 further including a ball adjustment member that movement of which said selectively inhibits movement of said body with respect to said ball.

3. The apparatus of claim 2 wherein said ball adjustment member comprises a lever that said selectively inhibits movement of said body with respect to said ball from freely movable to a substantial level of lockup.

4. The apparatus of claim 3 wherein said apparatus includes an upper ring that is in pressing engagement with an upper portion of said ball and in pressing engagement with said upper cavity.

5. The apparatus of claim 4 wherein said apparatus includes a lower ring that is in pressing engagement with a lower portion of said ball and in pressing engagement with said lower cavity.

6. The apparatus of claim 5 wherein said vertical movement includes said lower body vertically moving with respect to said upper body and said lower portion of said ball to said selectively inhibit movement of said body with respect to said ball.

7. The apparatus of claim 6 wherein said lower ring includes a ring flattened portion and said lower body includes a lower body flattened portion that cooperatively inhibit rotational movement with respect to one another.

8. The apparatus of claim 3 wherein said ball adjustment member includes a screw mechanism.

9. The apparatus of claim 8 wherein said screw mechanism includes a clamping screw with a broached serrated head that corresponds with a broached pocket defined by said lever.

10. The apparatus of claim 9 wherein movement of said lever engages said clamping screw with an internal screw that is threaded within said lever.

11. The apparatus of claim 10 further comprising a timing broach that is adjustable with respect to said screw mechanism that adjusts said lockup.
