Title:
ARTIFICIAL LAWN STRETCHING AND HOUSING DEVICE
Document Type and Number:
Japanese Patent JP3462651
Kind Code:

Abstract:

PROBLEM TO BE SOLVED: To attempt to enhance the workability of artificial lawn stretching and housing work by reducing a friction resistance between artificial lawns and their layout surfaces when stretching the artificial lawns or housing them.
SOLUTION: The artificial lawns T are divided into a plurality of segments along their stretching directions, thereby forming the artificial lawn layout surface while movable blocks 29a, 29b to 29j are provided opposed to the artificial lawns in such a fashion that they may rise freely. A support roller 31 is provided on the movable blocks 29a, 29b to 29j so as to support the rear surface of the artificial lawns, thereby providing a take-up drum 21 which supports the base end of the artificial lawns by winding up, on one side of the artificial lawns. On the other side, there is provided a winch 16 which locks a wire W connected to the artificial lawns T and winds up the wire.
