Abstract

The Support Post Securing system allows for the removal and reinstallation of a support post fitted with tapered sleeves (12) installed in a ground tube (16) secured in concrete. The holding ability can be increased by applying downward pressure to post (17). The taper of sleeves (12) when fitted to post (17) installed in ground tube (16) seals ground tube (16) against water or foreign material entering ground tube (16). A cap (40) is fitted to ground tube (16), when the post is removed, to allow passage of traffic over the ground tube (16) and exclude foreign materials and water from the ground tube (16). Cap and post removal tools are also disclosed and are operated from a standing position.

Support Post Securing System
The present invention relates to a support post securing system which allows for the simple installation and removal of a metal support post particularly although not exclusively for road direction signs - information signs - street furniture - pedestrian handrail - safety rails or the like.
The support post securing system can be used wherever a member is installed to be removabley attached to another member - generally one member is a metal support post fitted to a solid secure footing the footing can be at any angle.
Background to Invention
A common method of installing a conventional post is to dig a hole in the ground at an installation site for the post - insert the base of the post into the hole and fill the space betweeen the post and the sides of the hole with concrete when the concrete is set the post is rigidly fixed in place
In the event that the support post is damaged and requires removal from its location the concrete has to be broken up to allow the removal of the support post this has the disadvantage of being slow labour intensive and costly also the footing has to be replaced duplicating the cost
A better system would allow the simple removal of the damaged support post and the footing to be reusable The Support Post Securing System would allow the easy removal of the damaged post from the footing - the footing to remain in place and be reusable The Support Post Securing system allows the post to be removed and reinstalled in less than one minute by one man using a very simple tool Summary of I vention
Therefore it is the object of the invention to provide a Support Post
Securing System to address the shortfalls of the currently used method The practical re use of the existing footing after the removal of a damaged support post using minimal physical effort from a standing position - in one form of the invention the support post securing system allows for the refeasabfy fixing of a support post to a second member being a plastic house tubing set in concrete The support post securing system is comprised of two sleeves being tapered from their upper end towards their lower end being secured to the support post by coiffrtersunk screws recessed in the tapered sleeves to be received into the moulded plastic post housing tube being shaped to receive sleeves fitted to the lower end of the second member a support post
The locking ^plication can be increased _j$» the post being driven downwardly to increase the friction between the sleeves fitted to the support post and the post housing tube secured such as in concrete
