摘要： PURPOSE:To reduce the power requirement of fan and maintain a high level of ventilation efficiency by providing a lock key device which normally biases the roller to the damper in the radial direction of the lock bearing member. CONSTITUTION:A lock key device 20 is disposed above a lock bearing member 22. Where the static pressure inside the duct, for instance, is 5mmAq, if the wind pressure of outside air is less than that value, the weight of a balance weight 24 overcomes the wind pressure to cause a vane 16 to close the duct opening, and a roller 30 is locked in place by the engagement with the lock bearing part 25 of the lock bearing member 22. When the wind pressure of outside air exceeds 5mmAq, the engagement of the roller 30 with the lock bearing part 25 is released to allow the roller 30 to slide on the circumferential surface of the lock bearing member 22, which then rotates to open the vane 16. In the event the ventilation fan motor is operated, the vane 16 is automatically opened, whereas the vane 16 is closed to interrupt the outside air when the fan motor is stopped and the rush of outside air into the room is to be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a constant pressure release damper formed that a blade is released at a stretch when wind passing through a damper frame exceeds a set wind pressure, and airtightness during full closing can be ensured. SOLUTION: The constant pressure release damper comprises a lock receiving body 32 having an arcuate part 34 fixed at the shaft end of a rotary shaft protruded outward and a lock support part 36; a roller 22 rolled in adhesion to the arcuate part 34 of the lock support body 23 and engaged with and disengaged from the lock support part 36 of a lock support body 32; and a lock device 26 energizing in direction in which the roller 22 always approaches the lock support body 32. Further, the lock support part 36 has a slope 58 situated such that the roller 22 is forced upward in a direction to approach the lock support body 32 in synchronism with closing rotation of the blade 16 formed in succession to the arcuate part 34. When the blade 16 fully closes a flow passage V, the roller 22 is positioned only on the slope 58, security of full closing of the flow passage during setting of a balance between a wind pressure and a gravity moment around a rotary shaft and closing of the blade is reliably executed.

摘要： PROBLEM TO BE SOLVED: To provide an auxiliary film for an upper cover for enhancing gas sealability and water sealability of a film securing portion in a film structure used for enhancing water stop capability of the securing portion and holding thereof without damaging appearance. SOLUTION: An auxiliary film 22 for an upper cover has a base cloth 22a such as a tape-shaped heat resistant glass fiber cloth or the like the right and reverse surfaces of a part of which is coated with TEFLON 22b (R) and the right and reverse surfaces of the other part of which is coated with a rubber 22c. Since the film material comprises the glass fiber cloth part (white) and the rubber coated part (black), construction between the securing portion using the black rubber and the film panel 15 of the white film material has an effect to satisfy the conditions that hot-melt bonding of the same materials is indispensable and the existing appearance is not changed.

摘要： PURPOSE:To make it possible to unfailingly detect the flow of a wind with accuracy regardless strong winds and/or a turbulent flow by installing a photoelectric sensor in non-floating or floating part of the floating element of a guiding portion. CONSTITUTION:A floating element 9 which is caused to float up by the flow 8 of a wind through a standing tubular guiding portion 7 is provided within the guiding portion 7, and shelfs 26 for preventing the floating element 9 from getting out of the portion are provided in upper and lower openings 7a, 7b of the guiding portion 7, respectively, and the opening 7b of its lower end is mounted thereto so as to be in contact with the flow 8 of a wind. The ends of a projecting cable 10a and a light receiving cable 10b each of which ends is carried out of a photoelectric sensor 10 are mounted to respective mounting portions of the non-floating part of the floating element 9 of the guiding portion 7 so as to form a light projecting portion and a light receiving portion, respectively. Light signals output from the light projecting portion are reflected by the floating element 9 during the absence of the flow 8 of a wind so as to be put in the light receiving portion, which detects the absence of the flow of a wind accordingly. The floating element 9 moves upwardly during the presence of the flow 8 of wind so that light signals output from the light projecting portion will not be put in the light receiving portion because of the absence of the reflecting face of the floating element 9, and the flow of a wind is thereby detected.

摘要： PURPOSE: To provide an inexpensive fixed pressure open damper capable of an highly accurate adjustment of set air pressure and being simply fabricated in a short time. CONSTITUTION: This damper comprises a rotary shaft 14 penetrating a damper frame, a blade fixed to the rotary shaft 14, a rocking receptor 32 having a circular arc-shaped surface 34 and a rocking receptor part 36, a balance weight for energizing the blade in the direction of closing a flow passage, a roller 22 rolling on, in close contact with, the circular arc-shaped surface 34 and detachably engaging with the rocking receptor part 36 of the rocking receptor 32, and a rocking device 26 for energizing the roller 22 radially of the rocking receptor 32 at all times. The rocking receptor part 36 has a slope 58 formed continuously with the cricular arc-shaped surface 34 whereby when the blade closes the flow passage, the roller 22 is located on the slope 58 and hence a frictional component is reduced to ensure setting of stable air pressure.

摘要： PURPOSE:To provide a reinforcing method for an existing beam which has good efficiency of execution of a reinforcing work and can form a large-diameter opening without damaging the strength, rigidity and deformation capacity. CONSTITUTION:A cylindrical part 22 of a reinforcing body 20 is inserted in an opening 11 from the side of a beam 10, and bolts 15 passed through plural bolt passing holes 21b bored in the plate part 21 of the reinforcing body 20 is screwed in a female screw body 13 buried in a beam to fit the reinforcing body 20 to the beam 10. Clearances 30 are respectively formed between the inside surface of the plate part 21 and the side of the beam 10 and between the inner peripheral surface of the opening 11 of the beam and the outer peripheral surface of the cylindrical part 22. The clearances 30 are filled up with an adhesive agent, and the adhesive agent is hardened to fix the reinforcing body 20 to the beam 10. Accordingly, as the cylindrical part 22 of the reinforcing body is fixed in the opening 11, even if concentrated oblique tension stress is applied to the inner peripheral area of the opening, the stress is received by the cylindrical part of the reinforcing body, so that the inner peripheral area of the opening can not be broken and a large-diameter opening can be formed without damaging the strength, rigidity and deforming capacity.

摘要： PURPOSE:To reduce the power requirement of fan and maintain a high ventila tion efficiency by providing a damper with an attracting plate comprising a magnetic object fixedly attached to a rotary shaft and a permanent magnet near to the end of said rotary shaft. CONSTITUTION:The present device has an attracting plate 20 comprising a magnetic object fixedly attached to the end of a rotary shaft 14 which protrudes outside the frame 12, a balance weight 24 which swings with the movement of a vane 16 which is fixedly attached to the shaft end via an arm 22, and a permanent magnet 26 disposed near to the shaft end. Where the wind pressure is below the set pressure, the permanent magnet 26 attracts the attracting plate 20 to cause the vane 16 to close the duct opening F, and where the set wind pressure is exceeded, the vane 16 overcomes the attracting force to open the duct opening F. Therefore, the balance weight can be reduced compared with the system which relies on the weight and spring. As a result, the power require ment of the fan can be reduced, and a high ventilation efficiency can be maintained.
