both sides of the fence for example where a single fence separates the outfield of one baseball field from the outfield of another field while producing the same safety advantages to players on both of the fields after impact and once the player has recovered and removed his her weight from the fence panel 10 the panel readily returns to its upright position and is ready for further play without the need for repositioning or additional maintenance this rebound feature is created by the use of a wire gauge in the design of the spring 34 that is capable of producing a spring force sufficient to counterbalance the weight of the frame 12 the rebound feature eliminates any delay to the game due to an impact between a player and the fence as shown in fig3 a fence composed of fence panels 10 as described herein is constructed by installing a plurality of fence panels 10 immediately adjacent one another in a desired pattern e g the outline of a baseball or softball outfield or to separate adjacent athletic fields in installing the fence panels 10 it is not necessary that the fence panels be interconnected the fence panels do not require interconnection for stability leaving the fence panels unconnected allows each individual fence panel to fold over and rebound on its own without affecting the neighboring panels however the panels may be interconnected if necessary with hook and loop fastening fabric e g velcro u00ae strips or other releasable means thereby allowing individual panels to u201c break away u201d from adjacent panels upon impact one alternate means of interconnecting adjacent fence.
