POLE INSTALLATION DEVICE FOR ARTIFICIAL LAWN COURT
Document Type and Number:
Japanese Patent JP3136114
PROBLEM TO BE SOLVED: To facilitate installation and removal of a pole and to eliminate the need of a cover for a pole insert hole by making the height of a fiber bundle raised from an upper opening of a cylinder buried in a basement layer of a concrete foundation substantially flush with the artificial lawn in the periphery, and removably inserting a pole in the fiber bundle and helding the same.
SOLUTION: An outer cylinder 1 is buried at the time of forming a basement layer 5, and stopping pins 11, 11 as a fixing member locked in a grushed stone layer 6 are projected on the lower part of the outer periphery to stably fix and hold the outer cylinder. An inner cylinder 2 is removably inserted in the outer cylinder 1, and a fiber bundle 3 inserted and densely planted in the inner cylinder 2 is packed a little densely and planted densely, whereby when a gate pole 4 is inserted, the gate pole 4 can be fixed and supported firmly without oscillation, and when the gate pole 4 is pulled out during non-use, granular sand can be kept from entering the cylinder. The height is made equal to the leaf stems 9... in the periphery so as to prevent a disadvantage such that a ball takes an irregular behavior in the periphery.
