Our rain chain “Toh” now has a larger model in size L, which will drain water even for truly oversized roofs.
In addition to “Toh” rain chain with conventional size, a slightly larger “Toh L” is now available. Larger 60mm diameter is one and a half times larger than the 45mm of its predecessor.
Keeping the three varied cylinder sizes on the chain for a random feeling in its design, we increased the drainage capacity for adaptability to buildings with larger roofs.
The Toh rain chain was developed with a concept of positive adaptability to modern architecture by reviewing the conventional rain chains from the past in Japan. As a result, we now find a great increase in number of scenes that display buildings with rain chains.
Japanese rain chains are unique type of drainage system, particularly because it has a design aspect as its main feature.
It has an ornamental quality as it displays water flowing gracefully down from the roof using only natural force. When thinking about decorations with water, the first thing that comes to mind is water fountains, but principally, they use electricity to jet the water. There is a global call to reduce consumption of fossil fuel, and rain chains are eco-friendly water ornamentation with a function that operates cleanly and provides aesthetic pleasure.
Speaking of functions, in principle, common gutters collect rain water from the roof and let it flow down the pipe shaped drain. But there are situations, due to building design, where gutters and pipes cause complications for draining water. In these settings, rain chains that hangs vertically down could provide a valid solution for rain drainage.
Our mission on developing “Toh” was renewing the designs of rain chains that possess outstanding decorative and functional qualities but limited to matching traditional Japanese architecture and to provide a makeover by redesigning it to fit modern architecture. On top of its design evolution, the improved drainage capacity will increase its applicability with the arrival of the larger L size model.
