Socket retainer

1. A socket retainer assembly for retaining a ball of a support post, the assembly comprising:

a socket retainer body having a channel for receiving the ball and a hole formed therein, said hole being substantially perpendicular to said channel, said channel having a c-shape and said channel being constricted at an end opposite said hole for retaining the ball in said channel;

a pin disposed in said hole, said pin having a cutout formed therein corresponding to a diameter of the ball, said pin being rotatable for aligning said cutout with said channel to allow entry of the ball into said channel;

a spring disposed at said pin for preventing an unintended rotation of said pin;

and a cam surface disposed at one end of said hole on said socket retainer body; and a handle disposed on an end of said pin, said handle having a cam following surface, said cam following surface engaging said cam surface for alternatingly increasing and decreasing the compression on said spring.

2. The assembly according to claim 1 , wherein said hole has a counterbore at an end thereof opposite said cam surface and said pin has a shoulder disposed at end opposite said handle, said spring being disposed on said pin engaging said shoulder and said counterbore.

3. The assembly according to claim 1 , wherein a 360° rotation of said pin in said hole increases and decreases the compression of said spring at least twice.

4. The assembly according to claim 1 , wherein said pin has a locking position wherein said cutout is not aligned with said channel for locking the ball in the channel and an open position wherein said groove aligns with said channel for allowing the ball to enter and exit the channel.

5. The assembly according to claim 1 , wherein said handle has a D-shape and is affixed to said pin with a removable fastener.

6. The assembly according to claim 1 , wherein said pin extends beyond a top of said counterbore so as to be accessible for assisting in compression of said spring.

7. The assembly according to claim 1 , wherein said channel has a removable liner.

8. A socket retainer for retaining a ball of a support post, the socket retainer comprising:

a body having a channel formed therein for receiving the ball;

a rotatable pin disposed in said body substantially perpendicular to said channel, said pin having a shoulder, and said pin having a cutout formed therein corresponding to a diameter of the ball, said cutout for aligning with said channel by the rotation of said pin to allow entry of the ball into said channel; and

a spring disposed axially on said pin and abutting said shoulder for preventing an unintended rotation of said pin.

9. The socket retainer according to claim 8 , wherein said channel has a c-shape and said channel is constricted at an end opposite said pin for retaining the ball in said channel.

10. A socket retainer assembly for retaining a ball of a support post, the assembly comprising:

a socket retainer body having a channel for receiving the ball and a hole formed therein, said hole being substantially perpendicular to said channel;

a pin disposed in said hole, said pin having a cutout formed therein corresponding to a diameter of the ball, said cutout for aligning with said channel to allow entry of the ball into said channel;

a spring disposed at said pin for preventing an unintended rotation of said pin;

a cam surface disposed on said body at said pin; and

a handle disposed on an end of said pin, said handle having a cam following surface, said cam following surface engaging said cam surface for alternatingly increasing and decreasing the compression on said spring.

11. The socket retainer according to claim 10 , wherein a 360° rotation of said pin increases and decreases the compression of said spring at least twice.

12. The socket retainer according to claim 9 , wherein said pin has a locking position wherein said cutout is not aligned with said channel for locking the ball in the channel and an open position wherein said groove aligns with said channel for allowing the ball to enter and exit the channel.

13. The socket retainer according to claim 10 , wherein said handle has a D-shape and is affixed to said pin with a removable fastener.

14. The socket retainer according to claim 9 , wherein said channel has a removable liner.

15. A socket retainer assembly for retaining a ball of a support post, the assembly comprising:

a socket retainer body having a channel for receiving the ball and a hole formed therein, said hole being substantially perpendicular to said channel;

a pin disposed in said hole said pin having a shoulder, and, said pin having a cutout formed therein corresponding to a diameter of the ball, said pin being rotatable for aligning said cutout with said channel to allow entry of the ball into said channel; and

a spring disposed axially on said pin and abutting said shoulder for preventing an unintended rotation of said pin, said spring being a helical spring disposed on said pin.

16. The socket retainer according to claim 1 , wherein said channel and said cutout each have a respective longitudinal axis, said longitudinal axes being aligned with one other in an open position wherein said cutout aligns with said channel for allowing the ball to enter and exit the channel.

17. The socket retainer according to claim 1 , wherein said channel has a longitudinal side configured to allow the support post to project therethrough.

18. A socket retainer assembly for retaining a ball of a support post, the assembly comprising:

a socket retainer body having a channel for receiving the ball, said channel having two longitudinal ends, one of said longitudinal ends being constricted for preventing the ball from being removed from said channel said channel having a longitudinal open side between said two longitudinal ends, said longitudinal open side being configured for allowing the support post to project from said channel;

a hole formed in said socket body at said another longitudinal end, said hole being substantially perpendicular to said channel;

a pin disposed in said hole said pin having a shoulder, and, said pin having a cutout formed therein corresponding to a diameter of the ball, said cutout for aligning with said channel thereby allowing the ball to be inserted into or removed from said channel; and

a spring disposed axially on said pin and abutting said shoulder for preventing an unintended rotation of said pin and;

said channel and said cutout each having a respective longitudinal axis, said longitudinal axes being aligned with one other in an open position wherein said cutout aligns with said channel for allowing the ball to enter and exit the channel.
