Fence support structure, especially for equestrian show jumping

Image Number 3 for United States Patent #4368875.

A structure for supporting an obstacle, such as a so-called fence for use in equestrian show jumping, includes upright posts, each with a guide rail and a vertical row of holes in the guide rail. One or several obstacle support members are slidably adjustable up and down along the guide rails and arrestable in predetermined positions by a spring biased bolt which may be withdrawn manually from a hole for the adjustment movement. After adjustment the spring bias again urges the bolt into the respective hole.
