Claims
- 1. A board assembly for attachment to a table, said board comprising:
- a latching assembly adapted for releasable attachment to the table;
- a board pivotably connected to the latching assembly and defining an interior passage, said board having planar top and bottom surfaces and opposing first and second ends;
- a handle formed in the board, toward the first end;
- an indexing wheel disposed within the interior passage of the board and connected to the latching assembly; and
- a rod movably disposed inside the board and having an inner end, said rod being movable between an engaged position, wherein the inner end of the rod engages the indexing wheel so as to prevent movement of the board relative to the latching assembly, and a disengaged position, wherein the inner end of the rod is spaced from the indexing wheel so as to permit movement of the board relative to the latching assembly; and
- a grip connected to the rod and disposed proximate to the handle, said grip being movable between a locking position, wherein the grip moves the inner end of the rod to the engaged position, and an unlocking position, wherein the grip moves the inner end to the disengaged position; and
- wherein the latching assembly is disposed on the bottom surface of the board and is located toward the second end.
- 2. The board assembly of claim 1 wherein the rod longitudinally extends along the length of the board.
- 3. The board assembly of claim 1 wherein the handle is at least partially formed by a hand opening in the board, located toward the first end; and
- wherein the grip is disposed inside the board and is accessible through the hand opening.
- 4. The board assembly of claim 3 wherein the board assembly is generally translucent to X-rays between the latching assembly and the hand opening.
- 5. The board of claim 1 wherein the board and the rod are composed of material generally translucent to X-rays.
- 6. The board of claim 5 wherein the board and the rod are composed of plastic.
- 7. A board assembly for attachment to a table, said board comprising:
- a latching assembly adapted for releasable attachment to the table;
- a board pivotably connected to the latching assembly and defining a hand opening;
- a locking assembly connected to the latching assembly and the board, said locking assembly being operable to selectively secure the board from movement relative to the latching assembly; and
- a handle operatively connected to the locking assembly and disposed inside the board, said handle being accessible through the hand opening and movable between a locking position, wherein the locking assembly is activated, and an unlocking position, wherein the locking assembly is deactivated.
- 8. The board assembly of claim 7 wherein the board has planar top and bottom surfaces and opposing first and second ends; and
- wherein the latching assembly is disposed on the bottom surface of the board and is located toward the second end.
- 9. The board assembly of claim 8 wherein the hand opening is located toward the first end of the board.
- 10. The board assembly of claim 8 wherein the hand opening extends through the top and bottom surfaces.
- 11. The board assembly of claim 7 wherein the locking assembly comprises:
- an indexing wheel connected to the latching assembly, said indexing wheel defining a plurality of teeth; and
- a rod movably attached to the board and having a dog end, said rod being movable between an engaged position, wherein the dog end engages the teeth of the indexing wheel so as to prevent movement of the board relative to the latching assembly, and a disengaged position, wherein the dog end is spaced from the teeth of the indexing wheel so as to permit movement of the board relative to the latching assembly.
- 12. The board assembly of claim 11 wherein the locking assembly is disposed inside the board.
- 13. The board assembly of claim 7 wherein the locking assembly comprises a lock device connected between the latching assembly and the board, said lock device being selectively operable in a locking mode and an unlocking mode, said device having a fixed length when in the locking mode so as to prevent movement of the board relative to the latching assembly, and said device having an adjustable length when in the unlocking mode so as to permit movement of the board relative to the latching assembly.
- 14. The board assembly of claim 13 wherein the locking assembly is disposed on an exterior surface of the board.
- 15. A board assembly for attachment to a table, said board assembly comprising:
- a latching assembly adapted for releasable attachment to the table;
- a board pivotably connected to the latching assembly;
- a lock device connected between the latching assembly and the board, said lock device being selectively operable in a locking mode and an unlocking mode, said lock device having a fixed length when in the locking mode so as to prevent movement of the board relative to the latching assembly, and said lock device having an adjustable length when in the unlocking mode so as to permit movement of the board relative to the latching assembly.
- 16. The board assembly of claim 15 wherein the lock device is disposed on an exterior surface of the board.
- 17. The board assembly of claim 15 wherein the lock device is pivotally connected to the latching assembly.
- 18. The board assembly of claim 15 wherein the lock device is a gas-charged locking piston.
- 19. The board assembly of claim 15 wherein the lock device is a spring-loaded locking piston.
- 20. The board assembly of claim 15 wherein the lock device further comprises an actuating mechanism movable between a first position, wherein the actuating mechanism places the lock device in the unlocking mode, and a second position, wherein the actuating mechanism places the lock device in the locking mode.
- 21. The board assembly of claim 20 further comprising a grip connected to the actuating mechanism of the lock device, said grip being movable between a locking position, wherein the grip moves the actuating mechanism to the second position, and an unlocking position, wherein the grip moves the actuating mechanism to the first position.
- 22. The board assembly of claim 21 wherein the board defines a hand opening; and
- wherein the grip is disposed inside the board and is accessible through the hand opening.
