#CMT# #/CMT# The post (2) has a stake (3) including a tubular element (7) whose axis is parallel and near to that of a post. A nail (4) includes large and small bars (8, 9), where the large bar is fitted on the stake and partially driven into the ground. The small bar is completely driven in the ground for not constituting a projecting part. The nail has a rigid elongated element i.e. stiff-leg (10), inclined towards the ground, connecting the bars at respective upper ends of the bars and transmitting and distributing tilting forces that causes the post to tilt towards the small bar. #CMT#USE : #/CMT# Used for supporting a sidewall delimiting a track map on a horse-race course. Can also be applied for a hand-rail application. #CMT#ADVANTAGE : #/CMT# The rigid elongated element serves as a handle for withdrawing the nail by single movement, thus rapidly disassembling the post without the need for tools. The post enables modification of the track map on the race course in a time efficient and safety manner, while leaving minimum marking on grasses after the disassembling of the post. The rigid elongated element inclined towards the ground, connecting the bars at the respective upper ends of the bars and transmitting and distributing the tilting forces that causes the post to tilt towards the small bar, thus ensuring stability of the assembly of the post. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional side view of a post. 1 : Sidewall 2 : Track map delimiting sidewall supporting post 3 : Stake 4 : Nail 7 : Tubular element 8, 9 : Large and small bars 10 : Stiff-leg. |
