Mounting device

1. A mounting device for mounting an object on a support, the mounting device comprising:

a support member;

a base coupled to the support member to permit selective rotation of the base relative to the support member;

a slide arm coupled to the base and movable between a retracted position and a plurality of extended positions; and

a locking mechanism coupled with at least one of the slide arm and the base and operable to lock the slide arm relative to the base only when the slide arm is in the retracted position, wherein the locking mechanism includes a portion that can be grasped and pulled away from the base by a user to release the slide arm and base from a locked position relative to one another.

2. The mounting device of claim 1 , wherein the base can rotate 360 degrees relative to the support member.

3. The mounting device of claim 1 , wherein a toothed wheel is coupled between the support member and the base, and wherein the mounting device further includes a pawl selectively engageable with the toothed wheel to prevent rotation of the base relative to the support member when the pawl is engaged with the toothed wheel and to permit rotation of the base relative to the support member when the pawl is disengaged from the toothed wheel.

4. The mounting device of claim 3 , wherein the pawl is biased into engagement with the toothed wheel and is coupled to a knob to facilitate manipulation of the pawl by a user.

5. The mounting device of claim 1 , wherein the locking mechanism is in an unlocked position in all of the plurality of extended positions and automatically moves to a locked position when the slide arm is moved to the retracted position.

6. The mounting device of claim 5 , wherein the locking mechanism can only be moved from the locked position to the unlocked position by manipulation of the locking mechanism by a user.

7. The mounting device of claim 6 , wherein the locking mechanism includes a plunger biased toward the locked position, the locked position being achieved when the plunger enters an aperture in the base.

8. The mounting device of claim 1 , wherein the base includes one of a slot and at least one projection and the slide arm includes the other of the slot and the at least one projection, the at least one projection received in the slot such that an extent of travel of the at least one projection in the slot defines an extent of travel of the slide arm between the retracted position and a fully-extended position.

9. The mounting device of claim 1 , wherein the support member is a pedestal.

10. A mounting device for mounting an object on a support, the mounting device comprising:

a base configured to be coupled to the support;

a slide arm coupled to the base and movable between a retracted position and a plurality of extended positions; and

a locking mechanism coupled with at least one of the slide arm and the base and operable to lock the slide arm relative to the base only when the slide arm is in the retracted position, the locking mechanism including a plunger biased toward the locked position, the locked position being achieved when the plunger enters an aperture in the base, and a knob coupled to the plunger to facilitate manipulation of the locking mechanism by a user, wherein the locking mechanism is in an unlocked position in all of the plurality of extended positions and automatically moves to a locked position when the slide arm is moved to the retracted position and can only be moved from the locked position to the unlocked position by a user grasping and pulling the knob away from the base.

11. A mounting device for mounting an object on a support, the mounting device comprising:

a base configured to be coupled to a support member of the mounting device to permit selective rotation of the base relative to the support member, wherein the support member is configured to be coupled to the support;

a slide arm coupled to the base and movable between a retracted position and a plurality of extended positions;

a locking mechanism coupled with at least one of the slide arm and the base and operable to lock the slide arm relative to the base only when the slide arm is in the retracted position; and

a toothed wheel coupled between the support member and the base, wherein the mounting device further includes a pawl selectively engageable with the toothed wheel to prevent rotation of the base relative to the support member when the pawl is engaged with the toothed wheel and to permit rotation of the base relative to the support member when the pawl is disengaged from the toothed wheel.

12. The mounting device of claim 11 , wherein the pawl is biased into engagement with the toothed wheel and is coupled to a knob to facilitate manipulation of the pawl by a user.

13. A mounting device for mounting an object on a support, the mounting device comprising:

a support member;

a base coupled to the support member to permit selective rotation of the base relative to the support member;

a toothed wheel coupled between the support member and the base;

a pawl selectively engageable with the toothed wheel to prevent rotation of the base relative to the support member when the pawl is engaged with the toothed wheel and to permit rotation of the base relative to the support member when the pawl is disengaged from the toothed wheel;

a slide arm coupled to the base and movable between a retracted position and a plurality of extended positions; and

a locking mechanism coupled with at least one of the slide arm and the base and operable to lock the slide arm relative to the base only when the slide arm is in the retracted position.

14. The mounting device of claim 13 , wherein the pawl is biased into engagement with the toothed wheel and is coupled to a knob to facilitate manipulation of the pawl by the user.
