Portable adjustable boundary lines

Abstract

Our invention creates portable adjustable boundary lines for any ground surface. These boundary lines create portable adjustable fields, by attaching the webbing lines to lightweight sandbags that can be laid out by anyone on any desired playing surface. Any coach, player, or parent can use this invention to establish a field, a training grid, or a playing area for any sport such as, but not limited to, soccer, football, volleyball, basketball, lacrosse, hockey and baseball. These fields can be created on any ground surface such as grass, synthetic or artificial turf, indoor gymnasium, asphalt, concrete and sand.

1 . The adjustable marking device will provide enhance training sessions for any desired sport by allowing the user to easily create and adjust the boundary lines to accommodate his/her training regimen according to the age of the players and number of the player participating in the event. 
   
   
       2 . An adjustable marking device that creates a portable playing area on any ground surface such as grass, synthetic or artificial turf, gymnasium, asphalt, concrete and sand, for any sport such as, but not limited to, soccer, football, volleyball, basketball, lacrosse, hockey and baseball. 
   
   
       3 . The adjustable marking device is made of durable webbing elements and lightweight sandbags:
 a. the durable webbing material creates boundary lines that are easily assembled and can be adjusted as desired;   b. said webbing material contains Velcro straps, every 5 yard apart, so that the boundary lines can attach and adjust to each other to create any desired size and shape of the playing perimeters;   c. the webbing material uses the lightweight small sandbags that are placed on the webbing's Velcro strap once the desired size is met;   d. The lightweight sandbags contain a Velcro lining that allows attachment to the webbing's Velcro straps; purposely, the lightweight sandbag provides stability because the sandbag fastens the boundary lines to the playing surface so that the webbing lines are firmly attached to the desired ground.
