Title:
STRUCTURE FOR PREVENTING RAIN LEAKAGE IN TREE HOUSE
Document Type and Number:
WIPO Patent Application WO/2021/131135
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a light and relatively simple structure for preventing rain leakage in a tree house as much as possible. A tree house using a trunk 500 of a tree as a pillar inevitably has a gap 200 between the trunk 500 and a roof 100. Thus, a plurality of double-layer waterproof sheets 50a, 50b, and 50c are placed on top of the roof 100, so that each sheet can absorb rain water that would run down the trunk 500 of the tree and enter the gap 200, and can drain the rain water onto the roof 100. This makes it possible to prevent rain leakage in the tree house 10 through the gap 200 between the trunk 500 of the tree and the roof 100.
