Abstract:
PROBLEM TO BE SOLVED: To provide a natural ventilation device capable of easily changing direction of an indoor blow-out outlet. SOLUTION: This natural ventilation device of blow-out port direction selection system is constituted in such a way that an opening part for adjusting air stream whose peripheral fringe part is sealed in a laterally long communicating duct connected the inside of a building with its outside is formed, a laterally long vane is provided on a more opening part side of the building than the opening part for adjusting air stream so as to swing freely, and the opening part for adjusting air stream is blocked when the vane reaches the set maximum swing position. The communicating duct is constituted by a plurality of unit frame bodies, and one unit frame body among the plurality of unit frame bodies is exchanged to deflect the indoor blow-out the direction into utterly different direction.

PROBLEM TO BE SOLVED: To provide an interlocking opening/closing device for both sliding doors different in door widths, and a fire door. SOLUTION: Pulleys 5, 5 are provided in upper positions when the sliding doors are fully opened, and a wire rope 7 passed through a cylindrical guide implement 6 is endlessly stretched between the pulleys. After returning the sliding doors once into totally closed positions, a wire rope fixture 8 brought out from the narrow sliding door side is fixed to the wire rope on the side with no cylindrical guide implement, and the cylindrical guide implement is connected to a fixture 9 brought out from the wide sliding door side. When moving the wide sliding door in an opening direction by the wire rope 7 on the side with the cylindrical guide implement, a first fastener 10 is fastened into an abutting position P on the side of not moving the narrow sliding door 1a, out of the cylindrical guide implement end, and a second fastener is fastened into a position Q separated in the direction of the cylindrical guide implement from the position P of the first fastener 10 by a distance obtained by adding the door width difference of the sliding doors and the length of the cylindrical guide implement, to perform the opening/closing operation of the wide sliding door.

Abstract:
PROBLEM TO BE SOLVED: To provide an interlocking opening/closing device for double sliding doors different in width, and to provide a fire door. SOLUTION: The interlocking opening/closing device is constructed by arranging pulleys 5, 5 at locations that are above the respective sliding doors when fully opened, endlessly straining a wire rope 7 having a cylindrical guide 6 fitted thereon, between both the pulleys, once returning the double sliding doors to a fully closed position, thereafter fixing a wire rope fixture 8 overhanging from the narrow-width door to the wire rope on a side without the cylindrical guide, and then connecting a fixture 9 overhanging from the wide-width door to the cylindrical guide. Then a first fastener 10 of the cylindrical guide is fixed to the wire rope on a side with the cylindrical guide at a location P at which the cylindrical guide cannot move toward the narrow-width door from the door fully closed position, and a second fastener is fixed to a location Q separated from the first fastener fixed location toward the cylindrical guide by a distance equal to a difference between widths of both the sliding doors and the length of the cylindrical guide, to thereby carry out opening/closing operation of the wide-width sliding door.

Abstract:
PROBLEM TO BE SOLVED: To provide a fire-proof door with easy-open device equipment, provided with a close-contact device for bringing an opening part and the fire proof door into closely contact with each other when the door is fully closed, and capable of being easily opened when the door is opened. SOLUTION: In this fire proof door with an easy-open device, a rotary lever 8a is projected in a built-in pull 7 of the fire proof door 1, a rotary lever 8b shorter than the rotary lever 8a is mounted through a rotating shaft 9, and a tip of the rotary lever 8b and a linear moving tool 10 are linked, so that the linear moving tool 10 presses a door end of the fire proof door and the door is lightly moved from a fully-closed position to a contact releasing position, when the rotary lever 8a is made to fall down in the opening direction.
