Support structure for a fence
A supporting structure for fences is disclosed consisting of a base consisting of a bottom plate from which a box body open on one side and partly on the top surface projects which houses and supports a post, characterized in that in said structure horizontal and rotational displacement means of said post are provided with respect to said base, as well as adjustment means of the horizontal and rotational sliding motion of said post with respect to said base.
1. Supporting structure for fences, said supporting structure consisting of a base ( 1 ) consisting of a base plate ( 2 ), a box body ( 3 ) projecting upwardly from the base plate ( 2 ), said box body ( 3 ) open on one side and partly on the top surface, and a post ( 4 ) housed in the open side of the box body and supported by the box body ( 3 ), wherein said supporting structure comprises:
a horizontal and rotational displacement means for moving said post ( 4 ) of the structure with respect to said box body ( 3 ), said horizontal and rotational displacement means consisting of a through-screw ( 5 ) kept in engagement with said post ( 4 ) and housed in slits ( 6 ) formed in opposite walls ( 3 a , 3 b ) of said box body ( 3 ); and
adjustment means for horizontal and rotational sliding motion of said post ( 4 ) with respect to said box body ( 3 ),
wherein said post ( 4 ) has a tapered base ( 4 a ), a J-shaped bracket ( 7 ) welded at a location corresponding to a thickening point of a profile of the tapered base ( 4 a ) and a bush ( 8 ) attached to said J-shaped bracket ( 7 ) for receiving said through-screw ( 5 ).
2. The structure as claimed in claim 1 ) wherein said adjustment means for horizontal and rotational sliding motion of said post ( 4 ) with respect to said box body ( 3 ) consists of opposition spring means ( 11 , 13 a , 13 b ) kept in engagement with said bracket ( 7 ).
3. The structure as claimed in claim 2 ) wherein said opposition spring means ( 11 ) are vertically-arranged spring means, kept in engagement between said base plate ( 2 ) and a top surface ( 7 b ) parallel to the ground of said bracket ( 7 ), at a location corresponding to a hole ( 9 ) housing a fastening screw ( 10 ).
4. The structure as claimed in claim 3 ) wherein on said base plate ( 2 ) a cavity ( 12 ) housing said opposition spring ( 11 ) is furthermore provided.
5. The structure as claimed in 2 ) wherein said opposition spring means ( 13 a , 13 b ) are horizontally-arranged, kept in engagement between a front wall ( 3 c ) of the said box body ( 3 ) and a surface ( 7 c ) of said bracket ( 7 ) parallel and proximal thereto by screws ( 14 a , 14 b ) fastened on said front wall ( 3 c ).
6. The structure as claimed in claim 1 ), wherein said post ( 4 ) has a circular profile.
7. The structure as claimed in claim 1 ) wherein said post ( 4 ) has a polygonal profile.
8. The structure as claimed in claim 1 ) wherein said adjustment means for horizontal and rotational sliding motion of said post ( 4 ) with respect to said box body ( 3 ) consists of a resilient-disc system.
9. The structure as claimed in claim 1 ) wherein said adjustment means for horizontal and rotational sliding motion of said post ( 4 ) with respect to said box body ( 3 ) consists of a magnet system.
