On the other hand, the flow of outside air such as wind pushes the weather vane 52 and the arrow 51, and the wind vane 52 rotates in the direction along the flow of the outside air. The direction of the flow of outside air is determined based on the positional relationship between the direction of the weather vane 52 and the direction display unit 53.

The shaft 48 may be rotatably supported.

Second Embodiment Next, a second embodiment of the structure of the skylight of the present invention will be described with reference to FIG. As shown in FIG. 3, reference numeral 60 denotes a skylight structure, and the skylight structure 60 is supported by a window body 61 having a triangular cross-section when fixed to a building structure and an upper portion of the window body 61. The structure is provided with a discharge body 63 for discharging the air inside the building structure, and a windmill 62 rotatably supported by the discharge body 63 and rotated by the flow of outside air such as wind.

In the discharge body 63, for example, a propeller-type fan 64 that is rotated by the rotating force of the wind turbine 62 is provided inside the discharge body 63 that communicates with the inside of the window body 61. On the side wall of the discharge body 63, a waterproof plate 65 for preventing water such as rain from entering the space is juxtaposed along the substantially vertical direction, and these waterproof plates 65 extend downward to the outside. A discharge port 66 for discharging the air in the room to the atmosphere by the rotation of the fan 64 is formed between the waterproof plates 65.

A plurality of (four in the figure) support rods 68 having bases attached to 67, windmill blades 71 attached to the tip ends of these support rods 68, and a displacement mechanism 73 for changing the inclination of the windmill blades 71. It is configured to have.

The displacement mechanism 73 extends and contracts in a direction orthogonal to the support shaft 67, and has a plurality of (two in the figure) support arms 68 having a base attached to the support shaft 67. A weight 70 attached to the tip of each of the support arms 69, a windmill blade 71 attached to the support rod 68 rotatably around the axis of the support rod 68, the windmill blade 71 and the weight 70. And a transmission member (not shown) that connects the two through the support shaft 67. The support arm 68 has a structure in which an elastic member such as a spring or a spring that expands and contracts in the axial direction is attached.

In such a skylight structure, the flow of outside air pushes the wind turbine blade 71 of the wind turbine 62, and the wind turbine blade 71 rotates about the support shaft 67 as a central axis. The fan 64 rotates with the rotation of the support shaft 67, sucks the air inside the window body 61, and discharges the air from the discharge port 66. As the air inside the window body 61 is sucked, the air inside the room of the building structure is sucked into the window body 61.

On the other hand, when the flow of outside air such as strong wind is fast, the outside air strongly pushes the wind turbine 62, and the support shaft 67 rotates at high speed. A large centrifugal force is applied to the weight 70 attached to the support shaft 67, and the support arm 69 extends. As the support arm 69 extends, the transmission member pulls the wind turbine blade 71, the wind turbine blade 71 rotates about the axis of the support rod 68, the inclination of the wind turbine blade 71 changes, and the wind turbine blade 71 with respect to the flow of outside air. The resistance of is reduced. Therefore, the rotation speed of the wind turbine blade 71 is suppressed to a constant speed.

The exhaust body 63 is provided with the fan 64 that discharges the air in the building structure into the atmosphere by the rotating force of the wind turbine 62. The fan 64 can suck up the air in the room and discharge the air from the exhaust port 66 into the atmosphere. Therefore, even if the temperature difference between the room air and the outside air or the height difference between the room position and the discharge body 63 is small, the room air can be ventilated. Since the rotational force of the wind turbine 62 is converted into the rotational force of the fan 64, the cost required for the electric fan can be reduced and the noise of the electric fan can be suppressed.

Further, the wind turbine 62 is provided with a displacement mechanism 73 for changing the inclination of the wind turbine blade 71 of the wind turbine 62, and the displacement mechanism 73 is attached to the support shaft 67 of the wind turbine 62 in a telescopic manner. A support arm 69, a weight 70 attached to the tip of the support arm 69, a wind turbine blade 71 rotatably attached to a support shaft 67 of a wind turbine 62, and a support for the wind turbine blade 71 and the weight 70. Since there is a transmission member connected through the shaft 67, a large centrifugal force is applied to the weight 70 when the wind turbine blade 71 rotates at high speed during strong winds, and the weight 70 pulls the support arm 69 and the transmission member, and The inclination of the wing 71 changes. As the inclination of the wind turbine blade 71 changes, the resistance of the wind turbine blade 71 to the flow of outside air changes, and the rotational speed of the wind turbine blade 71 is suppressed to a predetermined speed. Therefore, even when there is a strong wind, the rotation speed of the windmill blades 71 can be suppressed, and the windmill 62 can be prevented from rotating beyond its capability, and the windmill 62 can be prevented from being damaged.

A modified example of the second embodiment will be described with reference to FIG. As shown in FIG. 4, the rotating shaft of the wind turbine 75 may be arranged in a direction orthogonal to the support shaft 67. This wind turbine is configured such that its rotation shaft is connected to a support shaft 67 via a gear, and has a wind turbine blade 71 attached to the front and a rudder 76 attached to the rear. Instead of the propeller type fan 64, a sirocco type fan 77 having a multi-blade may be used. In this case, a guide duct (not shown) extending from the sirocco type fan 77 to the exhaust port is provided.

In such a skylight structure 80, the outside air passes through the ventilation pipe 29, comes into contact with the damper 83, and flows into the shaft portion 82. The outside air that has flowed into the shaft portion 82 flows into the window body 21 and into the room of the building structure. On the other hand, when the flow of outside air such as strong wind is fast, the outside air strongly pushes the damper 83, and the damper 83 is folded back to the rudder 33 side with the fold line 84, and the outside air passes through the ventilation pipe 29.

The shaft portion 82 is rotatably supported by the window body 21 with respect to the window body 21. Since it is supported at the ends and extends in a substantially horizontal direction, the wind pushes the rudder 30 and the ventilation pipe 29 is arranged in the direction along the wind direction. The air flowing through the ventilation pipe 29 is sucked into the room through the shaft portion 82. For this reason, since the wind is taken into the room by the suction body 81, the air in the room can be ventilated even if the temperature difference or the height difference is small, and the ventilation capacity in the skylight structure 80 can be improved. Further, since the air is taken in by the suction body 81 and the indoor air is ventilated, the electric power required for the electric fan can be eliminated, the noise of the electric fan can be eliminated, and the cost required for the structure 80 of the skylight can be reduced.

According to the structure of the skylight according to claim 1, a window body, the periphery of which is fixed to the building structure, which takes in sunlight into the room of the building structure, and a ventilation member which is supported by the window body and allows outside air to pass therethrough. , The exhaust body supported by the ventilation body and discharging the air in the room into the ventilation body can eliminate the need to open and close the window body, and this window body can be used as a building structure. It can be tightly fixed, and water such as rain can be prevented from entering the building structure from the vicinity of the window body, and the indoor environment of the building structure can be improved. The ventilation body has one end supported by the window body, a shaft portion extending in a substantially vertical direction, a ventilation pipe supported by the other end of the shaft portion and extending in a substantially horizontal direction, and an outside of the ventilation pipe. Has a rudder fixed to one end of the ventilation pipe along the extending direction of the ventilation pipe, and at least one of the shaft portion and the ventilation pipe is rotatably supported with respect to the window body. Therefore, even if the direction of the outside air such as wind changes, the direction of the ventilation pipe changes along the direction of the outside air. Therefore, the outside air can be taken into the ventilation pipe without being affected by the wind direction, the reduction of the ventilation amount due to the wind direction can be prevented, and the ventilation capacity of the ventilation body can be maintained. Even when the flow of outside air such as strong wind is fast, the outside air passes through the ventilation pipe of the ventilation body, so that it is possible to suppress the increase of the wind pressure applied to the ventilation body and damage the ventilation body. Can be prevented, and the safety of the ventilation member can be maintained.

The exhaust body has one end connected to the inside of the chamber, one end connected to the suction part, and extending along the direction in which the ventilation pipe extends, and the other end below the rudder. Since the air in the exhaust section is pulled to the outside air flowing in the ventilation pipe, the air in the exhaust section is exhausted to the atmosphere, and the air in the room flows from the intake section to the exhaust section. Flow into. Therefore, even if the difference between the temperature of the room and the outside air is small, or if the difference between the height of the window and the height of the room is small, the air in the room can be discharged into the atmosphere, and It can ventilate the air sufficiently and improve the indoor environment. Since the air in the room is pulled by the flow of outside air and the air in the room is ventilated, the electric power required for the electric fan can be eliminated, and the noise caused by the operation of the electric fan can be eliminated, and the structure of the skylight. The cost required for the construction can be reduced, and the comfort of the environment inside the building structure can be improved.

The discharge body has the rotational force of the wind turbine. Since the fan is installed to discharge the air into the atmosphere, the window can be tightly fixed to the building structure and water such as rain can be prevented from entering the room. On the other hand, since the fan that operates by the rotational force of the wind turbine is provided, the indoor air can be sufficiently discharged into the atmosphere, and even if the temperature difference or height difference is small, the indoor air can be ventilated, and the structure of the skylight Ventilation capacity can be improved. Further, since the wind turbine is used, the cost required for the electric fan can be reduced and the generation of noise accompanying the operation of the electric fan can be suppressed.

According to the structure of the skylight of claim 3, the effect of claim 2 can be obtained, and the wind turbine is provided with a displacement mechanism for changing the inclination of the wind turbine blades of the wind turbine. The displacement mechanism includes a support arm attached to the rotary shaft of the wind turbine so as to extend and contract in a direction orthogonal to the rotary shaft, a weight attached to the tip of the support arm, and a rotary shaft of the wind turbine. Since the wind turbine blades are attached so as to be rotatable around the axis of the rotary shaft and the transmission member that connects the wind turbine blades and the weights through the rotary shaft of the wind turbine, the wind turbine blades during strong wind are When rotating at high speed, a large centrifugal force is applied to the weight, which pulls the support arm and the transmission member, and the tilt of the wind turbine blade changes. Along with the change in the inclination of the wind turbine blade, the resistance of the wind turbine blade to the flow of outside air changes, and the rotational speed of the wind turbine blade is suppressed to a predetermined speed. For this reason, even if the flow of outside air such as strong wind is fast, the rotation speed of the windmill blades can be suppressed, so that the windmill can be prevented from rotating beyond its capacity and damage to the windmill can be prevented. The safety of the structure of the skylight can be improved.

According to the structure of the skylight of claim 4, the periphery is fixed to the building structure, the window body for taking in sunlight into the room of the building structure, and the window body supported by the window body, the outside air into the room. A suction pipe for taking in the outside air, and the suction body is fixed to the ventilation pipe for taking in the outside air, the rudder along the extension direction of the ventilation pipe, and the outside air inside the ventilation pipe. And a cylindrical shaft portion for sending the air into the room, the shaft portion having one end supported by the window body and extending in a substantially vertical direction, and the ventilation pipe being supported by the other end of the shaft portion. Since it is configured to extend in a substantially horizontal direction and at least one of the shaft portion and the ventilation pipe is rotatably supported with respect to the window body, the flow of outside air such as wind pushes the rudder. , Ventilation pipes are arranged along the direction of the outside air. The outside air flowing through the ventilation pipe is sucked into the room through the shaft. Therefore, the window body can be tightly fixed to the building structure, and water such as rain can be prevented from entering the room. On the other hand, since the flow of outside air such as wind is taken into the room by the suction body, the air in the room can be ventilated even if the temperature difference and the height difference are small, and the ventilation capacity in the structure of the skylight can be improved. And, because the flow of outside air is taken in by the suction body and the air in the room is ventilated, the electric power required for the electric fan can be eliminated, the noise of the electric fan can be eliminated, and the cost required for the structure of the skylight can be reduced, It is possible to improve the environmental friendliness of the room in the building structure.

According to the structure of the skylight of claim 5, the effect of claim 4 can be obtained, and at the same time, the ventilation pipe is provided with a damper for sending the outside air in the ventilation pipe to the shaft portion, Since the damper has a structure in which the damper has a fold line that can be folded back toward the rudder side, the outside air passing through the ventilation pipe is brought into contact with the damper and sucked into the chamber from the shaft portion. Therefore, the outside air in the ventilation pipe can be directly taken in, the amount of suction of the outside air can be increased, the ventilation capacity of the structure of the skylight can be improved, and the indoor environment can be improved. On the other hand, when the outside air flows at a high speed, the outside air presses the damper, and this damper is folded back at its folds, and the outside air passes through the ventilation pipe, so that the wind pressure applied to the damper by strong wind etc. can be reduced It is possible to prevent the damper from being damaged by wind pressure, improve the safety of the damper, and improve the safety of the structure of the skylight.
