Abstract

PURPOSE:To provide the ventilating fan, convenient in maintenance and easy in opening operations of a panel and a shutter, by a method wherein the pivot of one link of four-links link mechanism, formed inside of a cover, effects opening and closing of the panel while the other link is extended in a frame body and is engaged with the opening and closing device of the shutter to operate in conjunction with the same device. CONSTITUTION:The link 8, extended from the link 23 of the four-links link mechanism toward the side of the frame body 1, is located below the fixed pin 19 of a movable lever 13 and pushes down the four-links link mechanism by the pivot of the movable lever 13 engaging slidingly with the fixed pin 19 to open the panel 4. The fulcrum 33 of a connecting link 18 is pivoted and the other fulcrum 34 of the same pushes down a connecting plate 11 toward the lower side of the fixed fulcrum 35 of the shutter 10 to open the shutter 10. In this case, the turning direction of the movable lever 13 is shown by an arrow sign (a) in the diagram and the horizontal component (b) thereof effects toward the inside of the frame body 1 while the horizontal component becomes substantially zero since the gravity of the panel is generally at the lower part, accordingly, the cover 2 and the panel 4 are pushed against the side of the frame body 1.

FIG. 1 shows a state in which the shutter 10 and panel 4 are closed. When the pull string 30 of the switch 14 is pulled, the movable lever 1
3 rotates downward against the force of the spring 17 and the fixing pin 19
hits the link S near the movable fulcrum 23 of the link 8, and then pushes the four-bar link mechanism downward. Therefore, the panel 4 opens, and at this time, the force in the rotational direction of the movable lever 13 is the arrow a in the figure.
As shown in , the horizontal component force acts toward the inside of the frame 1, and since the weight of the panel 4 is almost downward, there is almost no horizontal component force, and therefore the cover 2 and the panel 4 move toward the frame 1. Becomes pressed to the side.

In Figure 2, the movable lever 13 rotates and the fixed pin moves to the link 8.
The panel 4 and the shutter 10 are shown in the open state when they are pressed down to the stopper 36 while slidingly engaging the lever.At this time, the force in the rotational direction of the movable lever 13 becomes arrow a' in the figure, and its horizontal component force b' moves toward the cover 2, but the gravity at the center of gravity G of the panel 4 becomes e', and the component force in the rotational direction relative to the fixed fulcrum 3 becomes e', and the horizontal component force f.
' acts in the direction toward the frame l and cancels out the horizontal component force b'' of the movable lever 13. Therefore, the fixed fulcrum 12 of the movable lever 13, where the force exerted on the cover 4 to separate from the frame 1 is small, is Since it is located below the fixed fulcrum 5 of the four-bar link machine provided on the cover 2, the fixed pin is in contact with the link 8 near the fixed fulcrum 5 at the beginning of opening and closing, and its rotation direction is the same, so the panel 4 moves toward the distal end of the link 8 as it opens, its rotational moment increases as the rotational moment of the panel 4 increases. Therefore, the operating force of the drawstring 30 operated via the rod 16 remains approximately constant. The stopper at the tip of the link 8 is a stopper for preventing the fixed pin from coming off the link 8 since the movable lever 13 and the link 8 rotate in the same direction.

The distance between the fulcrum 33 of the connecting link 18 and the fixed fulcrum 12 is smaller than the distance between the hole 29 that engages the rod 16 of the movable lever 13 and the fixed fulcrum 12. Therefore, the operation force of the pull string 30 is small and the operation force is large. Since the plate 11 can be pushed down, the operating force required to open and close the shutter 10 is small. When the panel 4 is in the open state, the spring 2
The spring hook 27 of the link 23 at the other end of the link 23 is located on the panel 4 side with respect to the fixed fulcrum 5, and therefore the spring force is applied in the direction of opening the panel 4, reducing the force required to open the panel 4. doing.

FIG. 3 shows the state in which the cover 2 is attached and detached from the frame 1. The cover 2 is attached and detached while rotating around the engaging part K between the hook part 37 of the frame 1 and the protrusion 38 of the cover 2. Ru. At this time, as shown in FIG. 1, the fixed pin 19 of the movable lever 13 is positioned above the link 8, so its tip 36 rotates as shown by the arrow and can be attached or detached independently of the shutter opening/closing device 9. Sometimes it is located below the fixed pin I9 so that it can be interlocked with the shutter opening/closing device 9. Further, as shown in FIG. 4, when the shutter 10 is closed, even if the panel 4 is forcibly opened, it does not interfere with the shutter opening/closing device 9.

According to the present invention, the panel opening/closing mechanism has the link 8, which is the operating link, extending toward the frame l side through the four-bar link mechanism, so that the cover 2 is attached to the frame l when opening/closing the panel.
! The ventilation fan can be installed in the direction in which it is attached or in a state without any bulges, there is no fear that the cover 2 will fall off, and there is an advantage that there is no need to firmly mount the ventilation fan in the wall.

Furthermore, since the fixing pin 19 is located above the link 8, the panel 4 and cover 2 can be attached and detached regardless of the shutter opening/closing device, and even if the panel 4 is rotated when the shutter 10 is closed, the shutter cannot be opened or closed. This can be done without interfering with the device, and the panel can be opened and closed reliably when the shutter opening/closing device is operating.
