Retaining system

1. A retaining system comprising:

a base plate comprising a cam, a pin, and one or more alignment guides, wherein the cam defines a locked position and an unlocked position, wherein the cam is biased toward the locked position, and wherein the cam is configured to be retained in the unlocked position by the pin when the pin is in a raised position, engaged with the cam; and

a support shoe comprising one or more alignment surfaces and a locking surface wherein the support shoe is configured to be inserted into the alignment guides when the cam member is in the unlocked position;

wherein in response to insertion of the support shoe into the alignment guides, the support shoe is configured to disengage the pin from the cam, and in response to the cam advancing from the unlocked position to the locked position, the cam is configured to engage the locking surface of the support shoe and bias at least one of the alignment surfaces into engagement with at least one of the alignment guides.

2. The retaining system of claim 1 , wherein the pin is biased in the raised position.

3. A retaining system comprising:

a base plate comprising a cam, a pin, and one or more alignment guides, wherein the cam defines a locked position and an unlocked position, wherein the cam is biased toward the locked position, and wherein the cam is configured to be retained in the unlocked position by the pin when the pin is in a raised position, engaged with the cam; and

a support shoe comprising one or more alignment surfaces and a locking surface wherein the support shoe is configured to be inserted into the alignment guides when the cam member is in the unlocked position;

wherein in response insertion of the support shoe into the alignment guides, the cam is configured to engage the locking surface of the support shoe and bias at least one of the alignment surfaces into engagement with at least one of the alignment guides as the cam is advanced from the unlocked position to the locked position,

wherein the pin is biased in the raised position, and

wherein the pin is configured to urge the support shoe away from the base plate in response to the cam being moved from the locked position to the unlocked position.

4. The retaining system of claim 1 , wherein the support shoe is configured to be attached to a data recording device.

5. The retaining system of claim 1 , wherein the base plate is configured to be attached to a structural member of a vehicle.

6. The retaining system of claim 1 , wherein the location of the support shoe is fixed relative to the base plate when at least one of the alignment surfaces is engaged with at least one of the alignment guides and the cam is in the locked position.

7. The retaining system of claim 1 , further comprising a housing attached to the base plate that at least partially encloses the cam member.

8. The retaining system of claim 1 , wherein the cam comprises a keyway configured to receive a key for moving the cam from the locked position to the unlocked position.

9. A retaining system comprising:

a base plate comprising:

a plate;

one or more alignment guides;

a cam rotatable between a locked position and an unlocked position, wherein the cam is biased in the locked position; and

a pin defining an engaged position and a disengaged position, and wherein when the cam is in the unlocked position the pin engages the cam and retains the cam in the unlocked position; and

a support shoe configured to interface with the base plate, the support shoe comprising:

a body including a front surface and a back surface, wherein the front surface is configured to receive a device;

one or more alignment tabs, each alignment tab comprising an alignment tab engagement surface wherein each of the alignment tab engagement surfaces is configured at an acute angle relative to the back surface and is configured to engage one or more of the alignment guides of the base plate; and

a locking surface configured at an acute angle relative to the back surface, wherein the one or more alignment tabs are driven into one or more alignment guides in response to the cam pressing against the locking surface.

10. The base plate of claim 9 , wherein the pin is biased in the engaged position.

11. The base plate of claim 9 , wherein the cam rotates to the locked position in response to the pin being moved to the disengaged position.

12. The base plate of claim 9 , wherein the base plate is configured for semi-permanent attachment to a structure.

13. The base plate of claim 9 , wherein the cam comprises a keyway configured to enable rotation of the cam from the locked position to the unlocked position when engaged by a key.

14. The base plate of claim 9 , wherein the alignment guides each include an engagement surface and wherein at least two of the alignment guides include engagement surfaces that are arranged as a V relative to one another.

15. The support shoe of claim 9 , wherein the locking surface is located on a locking tab that extends parallel to the plane of the back surface.

16. The retaining system of claim 9 , wherein the cam is configured to engage the locking surface in response to the cam being rotated to the locked position.

17. The retaining system of claim 3 , wherein the support shoe is configured to be attached to a data recording device.

18. The retaining system of claim 3 , wherein the base plate is configured to be attached to a structural member of a vehicle.

19. The retaining system of claim 3 , wherein the location of the support shoe is fixed relative to the base plate when at least one of the alignment surfaces is engaged with at least one of the alignment guides and the cam is in the locked position.

20. The retaining system of claim 3 , wherein the cam comprises a keyway configured to receive a key for moving the cam from the locked position to the unlocked position.
