Spinner collar

1. A spinner collar comprising:

a collar having a bore with a bore axis;

a first grip engaging a first bearing which in turn engages the collar, the first bearing having an axis of rotation, the first grip engaging the first bearing in a manner so that as the first grip rotates relative to the first bearing about the axis of rotation of the first bearing, and the first grip and first bearing are blocked from moving relative to one another in a lateral direction perpendicular to the first bearing axis of rotation;

a second grip engaging a second bearing which in turn engages the collar, the second bearing having an axis of rotation;

a slot in the collar parallel to the bore axis, the collar being configured to selectively flex to accommodate and frictionally engage a device placed in the bore;

wherein the axis of rotation of the first bearing and the axis of rotation of the second bearing are not collinear when the collar is not flexed wherein when the collar is flexed to accommodate a device placed in the bore, the collar is rotatable about an axis of rotation of the collar that is perpendicular to the bore axis and collinear with the axis of rotation of the first bearing and the axis of rotation of the second bearing.

2. The spinner collar of claim 1 , wherein the collar further comprises:

a reinforcement rib parallel to the axis of rotation of the collar and perpendicular to the bore axis.

3. The spinner collar of claim 1 , wherein the first grip has a first grip surface that is perpendicular to the axis of rotation of the first bearing, the first grip surface being disposed on a side of the first bearing opposite the bore, and the second grip has a second grip surface that is perpendicular to the axis of rotation of the second bearing, and wherein the first grip surface is not parallel to the second grip surface when the collar is unflexed.

4. A spinner collar, comprising:

a collar having a bore with a bore axis;

a first bearing supported by the collar;

a first grip rotationally supported by the first bearing and configured to rotate relative to the collar about a first axis of rotation, the first grip having a first grip surface that is perpendicular to the first axis of rotation, the first grip surface being disposed on a side of the first bearing opposite the bore;

a second bearing supported by the collar; and

a second grip rotationally supported by the second bearing and configured to rotate relative to the collar about a second axis of rotation, the second grip having a second grip surface that is perpendicular to the second axis of rotation, the second grip surface being disposed on a side of the second bearing opposite the bore;

wherein the collar comprises a slot parallel to the bore axis and wherein the collar is configured to flex to accommodate a device in the bore in a manner so that the collar frictionally engages the device and the device rotates with the collar about the first grip and second grip and about a collar axis of rotation that is collinear with the first axis of rotation and the second axis of rotation; and

wherein the first axis of rotation is not collinear with the second axis of rotation when the collar is not flexed.

5. The spinner collar of claim 4 , wherein the collar is blocked from moving laterally relative to the first grip about the entirety of the first axis of rotation.

6. The spinner collar of claim 4 , wherein the first axis of rotation is perpendicular to the bore axis and the second axis of rotation is perpendicular to the bore axis when the collar is not flexed.

7. The spinner collar of claim 6 , wherein the first grip surface intersects and is contiguous across the first axis of rotation, and the second grip surface intersects and is contiguous across the second axis of rotation.

8. The spinner collar of claim 7 , wherein the spinner collar is configured so that a user can simultaneously engage the first grip surface and the second grip surface with fingers of one hand.

9. The spinner collar of claim 4 , wherein the collar defines a first cavity and a second cavity, and wherein the first bearing is received in the first cavity and the second bearing is received in the second cavity.

10. The spinner collar of claim 4 , wherein the first axis of rotation and the second axis of rotation are not collinear with the collar axis of rotation when the collar is unflexed.

11. The spinner collar of claim 10 , wherein the slot is equidistant from the first axis of rotation and the second axis of rotation.

12. The spinner collar of claim 10 , wherein the first grip surface is not parallel to the second grip surface when the collar is unflexed.

13. A spinner collar, comprising:

a collar having a bore with a bore axis;

a first bearing having an outer wall, the first bearing supported by the collar and having a first bearing axis of rotation;

a first grip rotationally supported by the first bearing, the first grip positioned on a side of the first bearing radially outward from the bore axis, and the first grip and collar are blocked from moving laterally relative to one another about the entire circumference of the first grip;

a second bearing having an outer wall, the second bearing supported by the collar and having a second bearing axis of rotation;

a second grip rotationally supported by the second bearing, the second grip positioned on a side of the second bearing radially outward from the bore axis, and the second grip and collar are blocked from moving laterally relative to one another about the entire circumference of the second grip; and

the collar comprising a slot parallel to the bore axis;

wherein the collar is configured to flex to accommodate a device in the bore in a manner so that the collar frictionally engages the device;

wherein the first bearing axis of rotation is not collinear with the second bearing axis of rotation when the collar is not flexed; and

wherein the first and second grips, first and second bearings, and the collar are configured so that the collar rotates relative to the grips about a collar axis of rotation that is collinear with the first bearing axis of rotation and the second bearing axis of rotation when the collar is flexed to accommodate the device in the bore.
