Self-rightening post system
A self-rightening post system is configured to secure a post in a casing in a desired or vertical orientation and to self-righten the post upon the removal of a deflecting force, such as from a car or lawnmower. A self-rightening post system utilizes a plurality of adjustable retainer assemblies that are configured around the post and coupled to a collar. Each of the adjustable retainer assemblies has an adjustment extension with a threaded portion in the collar to change the compression of a spring extending therefrom toward the post. A post flange may be coupled to the post end of the spring to provide a planar surface for exerting a retaining force on the post. The collar is configured over a casing and configured to rotated with respect to the casing. Retainer extensions extend from the collar down along the casing to secure the collar in position.
1. A self-rightening post system comprising:
a) a collar for receiving a post therethrough and having a plurality of threaded collar apertures;
b) a plurality of adjustable retainer assemblies coupled to the collar and wherein each of said plurality of adjustable retainer assemblies comprises:
i) an adjustment extension comprising:
1. a threaded portion that extends through said threaded collar aperture:
2. a length from an extended end to an adjustment end; wherein the extended end is outside of the collar and the adjustment end extends into the collar;
3. an adjustment feature for turning the adjustment extension within the threaded collar aperture
ii) a spring coupled to the adjustment extension and extending inward from the collar and comprising:
1. an attached end, coupled to the adjustment extension,
2. a post end, opposite the attached end;
3. a length from the attached end to the post end;
wherein the spring has a free spring portion between the attached end and the post end to enable the spring to compress when a post is offset by a deflecting force;
whereby the plurality of adjustable retainer assemblies are configured to self-righten said post after being defected by a deflecting force.
2. The self-rightening post system of claim 1 , further comprising a casing that extends down along the post from a bottom of the collar.
3. The self-rightening post system of claim 2 , further comprising a retainer extension that is attached to the collar and extends down along an inside surface of the casing to secure the collar over the casing.
4. The self-rightening post system of claim 3 , comprising a plurality of discrete retainer extensions configure around an inside surface of the collar.
5. The self-rightening post system of claim 1 , wherein the collar is circular and wherein the post is configured to rotate within the collar.
6. The self-rightening post system of claim 1 , further comprising an adjustment spring coupler that couples the attached end of the spring to the adjustment extension.
7. The self-rightening post system of claim 6 , wherein the adjustment spring coupler is cylindrical in shape and extends inside of the spring.
8. The self-rightening post system of claim 6 , wherein the adjustment spring coupler comprises an adjustment flange configured between the spring and the adjustment extension.
9. The self-rightening post system of claim 6 , further comprising a post spring coupler coupled to the post end of the spring.
10. The self-rightening post system of claim 9 , wherein the post spring coupler is cylindrical in shape and extends inside of the spring.
11. The self-rightening post system of claim 9 , wherein the post spring coupler comprises a post flange on an extended end to retain the post end of the spring.
12. The self-rightening post system of claim 1 , further comprising a post spring coupler coupled to the post end of the spring.
13. The self-rightening post system of claim 12 , wherein the post spring coupler is cylindrical in shape and extends inside of the spring.
14. The self-rightening post system of claim 12 , wherein the post spring coupler comprises a post flange on an extended end to retain the post end of the spring.
15. The self-rightening post system of claim 1 , wherein the plurality of adjustable retainer assemblies are configured on at least two opposing sides of the post.
16. The self-rightening post system of claim 1 , wherein said post is rectangular in cross-section.
17. The self-rightening post system of claim 1 , wherein the adjustment feature of the adjustment extension is a polygonal head that is fixed to the threaded portion.
18. The self-rightening post system of claim 1 , wherein the adjustment feature is configured inside of the collar.
19. The self-rightening post system of claim 1 , wherein the post is rectangular in cross sectional shape having four sides and wherein the self-rightening post system has four adjustable retainer assemblies with one of the adjustable retainer assemblies configured on each of the four sides of the post.
20. The self-rightening post system of claim 1 , further comprising a top-plate having a top plate aperture, wherein the post extends up through the top plate aperture, and wherein the top-plate is configured to slide with the post over the collar.
21. The self-rightening post system of claim 1 , further comprising a base retainer configured below the plurality of adjustable retainer assemblies and wherein the base retainer comprises a base retainer receiver to extend around an insert end of the post.
