Description

[Detailed Description of the Invention] (Field of Industrial Use) The present invention relates to an eaves ventilation device that automatically opens and closes a ventilation hole that communicates the eaves front wall portion and the back of a shed with changes in temperature.

(Prior Art) Conventionally, many ventilation openings have been devised as eaves ventilation devices that connect the attic and the wall.

(Problems to be solved by the device) However, in the structure like this conventional device, for example, in cold regions, warm air warmed by indoor heating is exhausted from the vents, or outside cool air is vented. There is a problem that it cannot be automatically opened and closed by coping with the temperature difference and that the cooling effect does not increase in high temperature areas.

(Means for Solving the Problem) The eaves ventilation device of the present invention has a plurality of ventilation holes formed in the front wall of the eaves, the ventilation holes communicating with the attic, and each of the ventilation holes is provided with a rotating lid. An air passage is formed in each of the rotary lids so that the vent can be opened and closed by the rotation of the lid, and one end of a swing rod for rotating the lid is fixed to each of the rotary lids. The other end of the oscillating rod is pivotally attached to a single operating rod, and this operating rod is supported by a shape memory material, and each movement is caused by pushing or pulling the operating rod by displacement of the shape memory material due to temperature change. The lid is rotated at the same time,
The above-mentioned vent hole is opened and closed.

(Operation) A ventilation passage is provided in the rotary lid body provided in the ventilation port, and one end of a swing rod for rotating the rotary lid body is fixed to the rotary lid body. An operating rod is pivotally attached to the other end of the swing rod, and the operating rod is supported by a shape memory material, so that the operating rod is pushed or pulled by the shape displacement of the shape memory material due to a change in temperature. By the movement of the operation rod, the rotary lid body is rotated to open and close a plurality of vent holes at the same time.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

The eaves ventilation device 1 is provided on the eaves front wall 2. Code 9
Is the roof of the building. The eaves ventilation device 1 has a plurality of ventilation holes 4 ... Which communicate with the attic 3 at the eaves front wall portion 2 at appropriate intervals (lateral direction), and each of the ventilation holes 4 is provided with a rotary lid 5. It is provided so that it can be opened and closed. Vent 4
Has a circular cross section, and the diameter (cross section) of the vent hole 4 is larger than the thickness of the eaves wall 2. Therefore, the vent hole 4 is formed by penetrating the eaves wall portion 2 from the outside of the building to the attic 3.

Cylindrical rotating lids 5 shown in FIG. 3 are fitted so as to rotate horizontally. The rotary lid 5 is formed of a short columnar body, and a ventilation path 51 having the same size as the shape of the openings 41 and 42 on the front and back sides of the ventilation port 4 is formed on the side surface of the columnar body.

The rotating lid 5 is not limited to such a columnar body, and may be a bottomed cylindrical body. One end 61 of a swing rod 6 for rotating the rotary lid 5 is fixed to the upper surface of the rotary lid 5. The other end 62 of each of the swing rods 6 is pivotally attached to one operating rod 7, and the plurality of rotating lids 5 described above can be rotated up to 90 degrees by pushing and pulling movements (arrows) of the operating rod 7. Will be moved. The base end 71 of the operation rod 7 is supported by one end of the shape memory material 8 (spring in this example). As the shape memory material 8, for example, a shape memory polymer whose displacement temperature can be freely set between -30 ° C and + 40 ° C is used. If the temperature change does not occur, the shape memory material 8 is reversibly displaced and pushes and pulls the operating rod 7 to swing the swinging rod 6, thereby swinging the swinging lids 5 in synchronization. Each rotating lid 5
Rotates the inside of the vent hole 4 in the lateral direction. By connecting the ventilation passages 51 of the rotary lids 5 to the front and rear openings 41 and 42 of the ventilation port 4, the air in the attic 3 can be discharged to the outside or taken in for ventilation. Further, when each of the rotary lids 5 is rotated in the opposite direction, the ventilation path 51 is closed by the ventilation port 4
Is hidden in the wall of the eaves-end wall portion 2 and the ventilation port 4 is blocked. Due to this interruption, the air is not ventilated. By ventilating the attic 3, it is possible to prevent condensation in the attic 3 and improve the durability of the building.
Moreover, there is an effect that the temperature of the entire building can be adjusted. The shape memory material 8 described above may be a so-called shape memory alloy, and the shape may be other than the spring.

It is preferable to provide support shafts 52, 52 on the upper and lower surfaces of the rotary lid 5 so that the rotary lid 5 can smoothly rotate.

Further, a case (not shown) having openings 41 and 42 may be fitted in each vent hole 4, and the rotary lid 5 may be housed in this case.

(Effects of the Invention) Since the eaves ventilation device of the present invention is configured as described above, the swinging rods and the operating rods of the rotating lids provided in the plurality of vents are made of the shape memory material. It is reversibly displaced by temperature, and by rotating this pivoting lid, the ventilation holes are opened and closed to automatically ventilate the attic, preventing condensation and improving the durability of the building. , The indoor temperature of the entire building can be kept comfortable.
