<p>The removable foot for a horse jumping fence has a base (1) whose upper face (6) is wider than the fence post (4). Two right angle pieces (7, 8) are fixed to the base, extending perpendicular to it. They hold 2 diametrically opposite corners of the post. A collar (9) extends round the post, with slight play, and is supported by oblique rods (10) fixed to opposite sides of the base. The base consists of two identical square tubes (2, 3) fixed together. The foot can have a second branch, crossing the first, with an extra rod to support the collar.</p> |
