Cap assembly for a t-post right of way line marker

1. In combination, a cap assembly for a right of way line marker and an upright support member having an exposed upper end, a lower end and an intermediate length running along a vertical axis, the lower end being positionable within a surrounding terrain in use to position the support member in an upright vertical position, the exposed upper end having a T-shape in cross section, at least along a portion of the length thereof, the assembly comprising:

a cap body having a conical exterior with an end opening and an initially open interior;

a mounting assembly including a lower, stationary disk sized to be received and retained within the end opening of the cap body, the lower, stationary disk having a top planar surface and having a T-shaped aperture therein for receiving the upper end of the support member, the mounting assembly also including an upper, sliding disk which is positionable within the cap open interior upon contact with the upper end of the support member and wherein each of the upper and lower disks have a top and bottom planar surfaces, respectively, the planar surfaces capable of being arranged in a plane generally perpendicular to the vertical axis of the support member when the support member is positioned in the surrounding terrain; and

wherein the upright support member has a series of raised nubs running in a line along the vertical axis thereof, wherein a locking detent is located on the top planar surface of the lower disk, the locking detent being a flexible flap which is movable between a relaxed position when in between a selected pair of raised nubs during installation, and a flexed position when riding over a selected tab on the support member for locking the lower disk and, in turn, the cap at a plurality of selected vertical locations on the support member after installation is complete.

2. The combination of claim 1 , wherein the upper and lower disks have mating engagement members located thereon, whereby the disks can be initially assembled with the respective planar faces of the disks in contact and with both disks located at the end opening of the cap.

3. The combination of claim 1 , wherein the flexible flap has a generally planar body when viewed in cross section having an outermost edge connected by opposing sidewalls to a base region located in the top planar surface of the lower disk, the flexible flap body forming an angle with respect to the top planar surface which is less than about sixty five degrees.

4. The combination of claim 3 , wherein the angle is in the range from about fifty to sixty four degrees.

5. The combination of claim 4 , wherein the angle is approximately sixty degrees.

6. The combination of claim 1 , wherein the T-shaped aperture in the lower disk has inwardly tapered sidewalls, as viewed from below, to facilitate entry of the upper end of the upright support member.

7. A method of installing a cap assembly on a right of way line marker which includes an upright T-shaped support member having an exposed upper end and a lower end, the lower end being positionable within a surrounding terrain in use to position the upright T-shaped support member in an upright vertical position, the installation method comprising the steps of:

providing a cap body having a conical exterior with an end opening and an initially open interior;

installing a mounting assembly within the end opening of the cap body, the mounting assembly including a lower, stationary disk sized to be received and retained within the end opening of the cap body, the lower, stationary disk having a top planar surface and having an aperture therein for receiving the upper end of the upright T-shaped support member, the mounting assembly also including an upper, sliding disk having a bottom planar surface, the upper sliding disk being positionable within the cap open interior upon contact with the upper end of the upright T-shaped support member;

inserting the upper end of the upright T-shaped support member through the aperture provided in lower disk, whereby the upper end of the upright T-shaped support member contacts the upper disk and drives the upper disk to an axially displaced location within the cap interior, the upper and lower disks serving to securely mount the cap body about the upper end of the upright T-shaped support member; and

wherein the upright T-shaped support member has a series of raised nubs running in a line along the vertical axis thereof, wherein a locking detent is located on the top planar surface of the lower disk, the locking detent being a flexible flap which is movable between a relaxed position when in between a selected pair of raised nubs during installation, and a flexed position when riding over a selected tab on the upright T-shaped support member for locking the lower disk and, in turn, the cap at a plurality of selected vertical locations on the upright T-shaped support member after installation is complete.

8. The method of claim 7 , wherein the upper and lower disks have mating engagement members located thereon, whereby the disks can be initially assembled with the top planar surfaces of the lower disk being in contact with the bottom planar surface of the upper disk and with both disks located at the end opening of the cap.

9. The method of claim 7 , wherein the flexible flap has a generally planar body when viewed in cross section having an outermost edge connected by opposing sidewalls to a base region located in the top planar surface of the lower disk, the flexible flap body forming an angle with respect to the top planar surface which is in the range from about fifty to sixty four degrees.

10. The method of claim 9 wherein the angle is approximately sixty degrees.

11. The method of claim 7 , wherein the lower disk is formed of a resilient synthetic material and wherein the locking detent is integrally formed as a part of the top planar surface of the lower disk.
