Rotatable turret assembly for checkout stand

1. A checkout stand assembly, the checkout stand assembly comprising:

(a) a circular turret rotatable about a central axis,

(b) a stop on a semicircular arc concentric with the central axis,

(c) a cabinet surface at least partially surrounding a perimeter of the circular turret,

(d) a damping cylinder including a piston rod, the piston rod having a first end and a second end,

wherein the first end is pivotally attached to a location outside the perimeter of the circular turret, the second end is pivotally attached to a location on the circular turret offset from the central axis, such that when the circular rotatable turret rotates from a first position abutting the stop to a second position abutting another stop, the cylinder provides pneumatic assistance during about a half of the arc and hydraulic dampening during about half of the arc, and

whereby the damping cylinder causes rotation of the turret to slow as the turret approaches the second position or the first position.

2. The assembly as claimed in claim 1 , further comprising a cabinet at least partially surrounding a perimeter of the circular turret.

3. The assembly as claimed in claim 2 , wherein the stops protrude from the circular turret at opposite locations on a semicircular arc concentric with the central axis.

4. The assembly as claimed in claim 1 , further comprising at least two stops protruding from the circular turret at opposite locations on a semicircular arc concentric with the central axis.

5. The assembly as claimed in claim 1 , further comprising a display mounted on a top surface of the circular turret.

6. The assembly as claimed in claim 1 , further comprising a lock along the arc.

7. A checkout stand comprising:

(a) a circular turret rotatable about a central axis,

(b) a cabinet surface at least partially surrounding a perimeter of the circular turret, and

(c) a damping cylinder including a piston rod having a first end and a second end.

8. The checkout stand as claimed in claim 7 , wherein the first end is pivotally attached to a location outside the perimeter of the circular turret, the second end is pivotally attached to a location on the circular turret offset from the central axis, such that when the circular rotatable turret rotates from a first position abutting a stop to a second position.

9. The checkout stand as claimed in claim 7 , whereby the damping cylinder causes rotation of the turret to slow as the turret approaches the second position, and when the circular turret rotates from the second position to the first position.

10. The checkout stand as claimed in claim 7 , further comprising a stop on a semicircular arc concentric with the central axis.

11. The checkout stand as claimed in claim 10 , wherein the stop protrudes from the circular turret.

12. The checkout stand as claimed in claim 7 , further comprising a display mounted on a top surface of the circular turret.

13. The checkout stand as claimed in claim 7 , further comprising a cabinet at least partially surrounding the turret.

14. The checkout stand as claimed in claim 7 , wherein the piston rod withdraws into the damping cylinder, and damping fluid in the cylinder is compressed and the resistance causes the speed of rotation of the turret to slow.

15. The checkout stand as claimed in claim 7 , further comprising a handle.

16. The checkout stand as claimed in claim 7 , wherein rotation of the turret is motorized.

17. The checkout stand as claimed in claim 7 , wherein the damping cylinder holds the turret in place.

18. A turret rotatable about a central axis comprising:

(a) a pair of stops protruding from the circular turret at opposite locations on a semicircular arc concentric with the central axis,

(b) a damping cylinder including a piston rod, the piston rod having a first end and a second end,

wherein the first end pivotally attached to a location outside the perimeter of the circular turret, the second end pivotally attached to a location on the circular turret offset from the central axis, such that when the circular rotatable turret rotates from a first position abutting one of the stops to a second position abutting the other one of the stops, and

whereby rotation slows as the circular rotatable turret approaches the second position, and when the circular turret rotates from the second position to the first position, the rotation slows as the circular rotatable turret approaches the first position.

19. The turret as claimed in claim 18 , further comprising a display mounted on a top surface of the circular turret.

20. The turret as claimed in claim 18 , further comprising a scale.
