Title: Pressurized air blasting device for controlling smoke disaster, window opening and closing device, and method therefor
Inventor: KAKUMOTO JUNICHI
IPC: F24F7/06
Filed: 1985-03-02
Abstract: PURPOSE:To control and suppress the rapid spread of generated smoke at a fire in a building by blasting pressurized air into the inside of common spaces such as stairs, corridors, etc. from the upper part at the outside of the building. CONSTITUTION:When a pressurized air blasting device 21 is installed at the upper part of a building to generate minute pressure overcoming the pressure causing updraft, the updraft is suppressed and on the contrary, exhaust streams are formed at rooms 11-18 at each floor. For instance, when smoke is generated at the place 4 of the first floor, air flows out-side at all each floor and therefore, the spread of smoke is able to be made small. That is, necessary time for refuge at an early stage of fire occurrence is lengthened substantially and the safety of absolutely necessary common spaces at the refuge time is improved. This method is more effective as a building is smaller in its cross section and higher in its stories and also has such effects as high reliability and providing no large restriction for the structure of the building.

Title: Honycomb type independent suspension air mat
Inventor: INABA CHITOSE
IPC: A47C27/08
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To eliminate the irregularities of a mat surface, ensure a wide effective contact area between a human body and the mat, and reduce the pressure added per unit area of the human body surface by mounting an air cell vertically to a body. SOLUTION: A mat having a number of air cells 2 for containing air which are mounted vertically to a body 1 is manufactured. The individual air cells 2 are independent, and a clearance is formed in the boundary part, so that each individual air cell 2 never interferes with the air cells 2 around it. When air is put in the mat, an air pump having pressure regulating function is used so that the pressure is constant. Consequently, the individual air cells 21 work as air springs vertically extended and contracted in use, and the mat surface is recessed according to the line of a human body to support the body. At this time, every air cell 2 has a constant internal pressure regardless of its extension or contraction.
