Abstract

A coupler for removable coupling an object to a support. The coupler includes a cover, a ring, and a base. The cover couples to the support. The ring includes a first arm, a second arm, a third arm, a fourth arm, a first stop, and a second stop. Each arm of the ring is formed of a resilient material. The ring is positioned in a cavity of the cover. The base couples to the accessory. The base cooperates with the cover and the ring to couple to the cover and to rotate from a decoupled position to an intermediate position and further to a clocked position.

First claim

What is claimed is:

1. A system for coupling an accessory to a support and for positioning the accessory with respect to the support, the system comprising:
a cover for coupling to the support, the cover comprising a wall and a cavity, the wall having an opening therethrough;
a ring comprising an opening therethrough, a first arm, a second arm, a third arm, a fourth arm, a first stop and a second stop, each arm formed of a resilient material, the ring positioned in the cavity; and
a base for coupling to the accessory, the base comprising a post, the post comprising a first protrusion, a second protrusion, each protrusion comprising a surface spaced apart from a surface of the base to form a slot between each protrusion and the surface of the base, the post inserted through the opening in the cover and the opening in the ring to position the base in a decoupled position, the base rotatable in a first direction to an intermediate position and further rotatable in the first direction to a locked position; wherein:
the first arm cooperates with the first protrusion and the third arm cooperates with the second protrusion to resist rotation of the base between the decoupled position and the intermediate position;
the first arm and an end portion of the second arm cooperate with the first protrusion, and the third arm and an end portion of the fourth arm cooperate with the second protrusion to retain the base in the intermediate position;
the second arm cooperates with the first protrusion and the fourth arm cooperates with the second protrusion to resist rotation of the base between the intermediate position and the locked position;
the second arm and the first stop cooperate with the first protrusion, and the fourth arm and the second stop cooperate with the second protrusion to retain the base in the locked position; and
while the base is rotated out of the decoupled position, a portion of the wall of the cover is positioned in the slot between the protrusions and the surface of the base such that the protrusions cooperate with the cover to couple the base to the cover.

2. The system of claim 1 wherein:
the post further comprises a third protrusion and a fourth protrusion; and
while the base is positioned in the locked position, the end portions of the second arm and the fourth arm apply a force on the third protrusion and fourth protrusion respectively to retain the base in the locked position.

3. The system of claim 2 wherein the first protrusion and the second protrusion extend a first distance away from the axis, the third and fourth protrusions extend a second distance away from the axis, the first distance is greater than the second distance.

4. The system of claim 1 wherein the end portion of each arm has a bulbous shape.

5. The system of claim 1 wherein while the base is positioned in the intermediate position, the first arm applies a first force on the first protrusion, the second arm interferes with movement of the first protrusion, the third arm applies a second force to the second protrusion, and the fourth arm interferes with movement of the second protrusion to retain the base in the intermediate position.

6. The system of claim 1 wherein a magnetic force between the base and the cover further operates to couple the base to the cover.

7. A system for positioning an accessory with respect to a support, the system comprising:
a cover for coupling to the support, the cover comprising a cavity and a wall, the wall having an opening therethrough;
a ring comprising an opening therethrough, a first arm, a second arm, a third arm, a fourth arm, a first stop, and a second stop, the ring positioned in the cavity, each arm formed of a resilient material, each arm comprising a bulbous end portion; and
a base for coupling to the accessory, the base comprising a post, the post comprising a first protrusion, a second protrusion, and an axis, the post inserted through the opening in the cover and the opening in the ring to position the base in a decoupled position, the base rotatable in a first direction to an intermediate position and further rotatable in the first direction to a locked position; wherein:
responsive to a first rotational force applied to the base in the first direction, the first protrusion and the second protrusion push the bulbous end portions of first arm and the third arm respectively away from the axis so that the first protrusion and the second protrusion move along the first arm and the third arm until rotational movement is resisted by contact of the first protrusion and the second protrusion with the bulbous end portion of the second arm and fourth arm respectively thereby reaching the intermediate position;
while the first protrusion and the second protrusion hold the bulbous end portions of the first arm and the third arm respectively away from the axis, the first arm and the third arm apply a force on the first protrusion and the second protrusion respectively so that the base resists rotating to the decoupled position;
responsive to a second rotational force applied to the base, the first protrusion and the second protrusion push the bulbous end portions of the second arm and the fourth arm respectively away from the axis, move past the first arm and the third arm so that the first arm and the third arm are no longer pushed away from the axis, move past the bulbous end portions of the second and fourth arms, and contact the first stop and the second stop respectively thereby reaching the locked position; and
the first stop and the second stop halt further rotation of the base in the first direction, and the bulbous end portions of the second arm and the fourth arm resist rotation of the base out of the locked position to the intermediate position.

8. The system of claim 7 wherein:
each protrusion comprises a surface spaced apart from a surface of the base to form a slot between each protrusion and the surface of the base;
while the base is positioned in the decoupled position, the wall of the cover is not positioned in the slot, so the base may be separated from the cover; and
while the base is rotated out of the decoupled position, a portion of the wall of the cover is positioned in the slot between the protrusions and the surface of the base such that the protrusions cooperate with the cover to couple the base to the cover.

9. The system of claim 7 wherein:
the post further comprises a third protrusion and a fourth protrusion; and
while the base is positioned in the locked position, the bulbous end portions of the second arm and the fourth arm apply a force on the third protrusion and fourth protrusion to further resist rotation of the base out of the locked position.

10. The system of claim 9 wherein the first protrusion and the second protrusion extend a first distance away from the axis, the third and fourth protrusions extend a second distance away from the axis, the first distance is greater than the second distance.

11. The system of claim 7 wherein a magnetic force between the base and the cover further operates to couple the base to the cover.

12. A system for positioning an accessory with respect to a support, the system comprising:
a cover for coupling to the support, the cover comprising a cavity and a wall, the wall having an opening therethrough;
a ring comprising an opening therethrough, a first arm, a second arm, a third arm, a fourth arm, the ring positioned in the cavity, each arm formed of a resilient material; and
a base for coupling to the accessory, the base comprising a post, the post comprising a first protrusion, a second protrusion, a third protrusion, and a fourth protrusion, and an axis, the p
