Prevent the fall of window frames with elastic strain energy from wire elongation! Prevent secondary disasters such as the expansion of damage caused by earthquakes! *Patent obtained
The energy from the falling window frame is primarily absorbed by the elastic strain energy due to the elongation of the wire. Additionally, a safety factor of more than twice the breaking load of the wire is ensured! This technology can be applied to school gymnasiums, school buildings, factories, museums, public halls, and more, serving as a comprehensive seismic performance enhancement technique. 【Features】 ■ Developed a method where the fall prevention wire is horizontally stretched, allowing the window frame to hang ■ Safety confirmed with a load gauge ■ Can be utilized as a seismic performance enhancement technology, etc. *For more details, please refer to the catalog or feel free to contact us.

Company information
Kobayashi Aluminum Industry Co., Ltd. is a company located in Fuchu City, Tokyo, engaged in advanced disaster prevention technology commercialization support projects. During the Great East Japan Earthquake, we confirmed 220 cases of window damage, primarily in the three affected prefectures. Among these, 34 cases were classified as "dangerous cases where the entire window frame fell." Our company has devised a device to prevent the falling of window sashes associated with the collapse of window frames. If you have any inquiries regarding the practical application of disaster prevention technology, please feel free to consult with us.
