Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a ventilation hole device that is attached to a wall, ventilation window, etc. of a building such as a house or a storeroom.

(Prior Art) Conventionally, as a ventilation hole device for ventilation of buildings, for example, as described in Japanese Utility Model Publication No. 55-30221,
A fixed plate with a plurality of ventilation holes bored therein, and a movable plate that overlaps the fixed plate and can be moved back and forth, the movable plate has a plurality of ventilation holes bored therein that correspond to the ventilation holes of the fixed plate. By reciprocating the movable plate, the ventilation holes of both plates communicate with each other and the ventilation holes are opened, and the ventilation holes of one of the movable plate and the fixed plate are closed by the plate surface between the ventilation holes of the other plate. There is something.

(Problems to be Solved by the Invention) In such conventional ventilation hole devices, the ventilation holes are opened and closed by manually moving the movable plates one by one. In other words, when the outside air temperature is high in the summer, ventilation holes are opened to ventilate the building, and when the outside air temperature is low in the winter, the ventilation holes are closed to prevent cold air from entering the building. Manual opening and closing is required, and people tend to forget to open and close the ventilation holes, leaving the ventilation holes open or closed throughout the year. However, if the ventilation holes remain closed during the summer, ventilation will not take place, which is bad for the health of the residents (11!) and has a negative impact on the building. If this happens, the warm air inside the room will be lost due to heating, which is uneconomical, and in areas with heavy snowfall, wind and snow will enter the room, which is undesirable.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned conventional problems, and provides a ventilation hole that can automatically open and close based on changes in outside temperature due to seasonal changes. It provides equipment.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a fixing plate with a plurality of ventilation holes 2. The lower edge of the fixing plate 1 is bent in an inverted J shape to form a lower guide groove 3, and the fixing plate 1 faces oppositely. A frame piece 5 with a hanging piece 51 hanging thereon by bending the tip of the cross-sectional shape is attached to the upper edge, and an upper guide groove 4 is formed between the hanging piece 51 and the side of the upper edge of the fixing plate 1. has been done.

Reference numeral 6 denotes a movable plate in which a plurality of ventilation holes 7 are bored. 7 is bored corresponding to the ventilation hole 2 of the fixed boardwork. Note that the ventilation hole 2.7 is not limited to the vertically elongated rectangular shape shown in the figure, but may have an arbitrary shape.

8 is a shape memory alloy body formed into a coil spring shape.

The shape memory alloy body 8 is made of Ti-old yarn or Cu-based alloy, and has a so-called shape memory function in which the shape memorized at high temperature returns to the original shape when heated even if it is deformed at room temperature. One-way shape memory alloys that remember only the shape at high temperatures, two-way shape memory alloys that change shape reversibly with temperature cycles, and omnidirectional shapes where the shapes at high and low temperatures are completely reversed. Any memory alloy can be used.

The shape memory alloy body 8 is inserted into the sliding holes 93 and 94 of the two protruding pieces 91 and 92 of the fixture 9 fixed to the hanging piece 51 of the frame piece 5.
The -HA811 of the alloy body 8 is inserted and fixed into the fixing hole 95 of the protrusion piece 91, and the other end 812 of the alloy body 8 is inserted into the fixing hole 95 of the protrusion piece 91. A screw 12 is screwed into the tip of the zero actuating rod 10 which is inserted and fixed in the hole 11, and a fixing rod provided on the side of the upper edge of the movable plate 6 is inserted through a long hole 52 bored in a hanging piece 51 near the screw 12. The piece 61 is made to protrude, and the fixed piece 61 and the tip of the actuating rod 10 are screwed together with a nand.

The alloy body 8 may have a plate spring shape instead of the coil spring shape shown.

(Function) When using the ventilation hole device of the present invention, the fixing plate 1 is fitted into the location where the device of the present invention is to be installed in a building, for example, a ventilation hole in the wall of the building, and the device is attached using mounting screws or the like. That's fine.

The ventilation hole device installed in this way is movable because the shape memory alloy body 8 that connects the fixed plate 1 and the movable plate 6 deforms into a memorized shape according to changes in temperature throughout the year. When the plate 6 is moved, both the ventilation holes 2 of the fixed plate 1 and the ventilation holes 7 of the movable plate 6 are opened and communicated with each other during high temperatures in summer, and the ventilation holes 2.
7 are mutually closed off by the plate surfaces between the opposing ventilation holes.

(Effects of the Invention) Since the present invention has the above structure, the shape memory alloy body deforms according to changes in outside temperature, so the ventilation holes of the ventilation hole device are automatically opened and closed in summer and winter. It is convenient because there is no need to manually open and close the opening and closing operations each time, and various problems caused by forgetting to open and close the opening and closing operations can be eliminated at once.

In addition, if the shape memory alloy body is formed in the shape of a coil spring or a leaf spring, a portion of the maximum deformation of the alloy body due to temperature change is used for the reciprocating movement of the movable plate to generate a large force. This is preferable because the stress generated within the alloy body is easily absorbed by the elasticity of the spring.
