Claims (5)

A plurality of shutter units coupled to a frame of a rectangular frame through a plurality of rotation shafts provided on both sides and rotated in interlock with each other inside the frame;
A fixed guide part installed on one side of the frame and having a plurality of angle adjustment grooves formed on the outside of the slit formed vertically, one side is coupled to any one of the plurality of rotation shafts, and the other side passes through one side of the frame and the slit An operation lever protruding to the outside and configured to control the opening and closing angles of the shutter unit when rotating, and a fixing protrusion protruding from a surface facing the fixing guide part during rotation, which is provided rotatably from the other side of the operation lever, is the angle Manual opening/closing unit provided with a rotation handle detachably coupled to the adjustment groove; and
A rotation lever having one side coupled to one or the other of the plurality of rotation shafts and the other side protruding to the outside of the other side of the frame, and a shape memory alloy spring and a return spring each end coupled to the other side of the rotation lever Including, but above a preset reference temperature, the shape memory alloy spring is deformed to open the shutter unit as the rotation lever rotates in one direction, and below the reference temperature, the rotation lever rotates in the other direction by the elastic force of the return spring and an automatic opening/closing unit for closing the shutter unit.
The rotating handle,
a coupling member coupled to the operation lever;
The handle is rotatably coupled to the coupling member in the transverse direction so as to be folded or unfolded based on the operation lever, and the fixing protrusion protruding from the surface facing the fixing guide part during rotation is detachably coupled to the angle adjusting groove. ; and
One side is coupled to the handle and the other side is in close contact with the coupling member, in close contact with either side of the coupling member in a state in which the handle is unfolded based on the operating lever, and in a state in which the handle is folded based on the operating lever and an elastic member providing elastic force so that the handle is maintained in an unfolded state or a folded state, respectively, as it is in close contact with the other side of the coupling member; and
When the shutter part is automatically opened and closed by the automatic opening and closing unit in a state in which the rotation handle is separated from the angle adjustment groove, the rotation handle rotates together with respect to the rotation axis, and the shape memory alloy spring is damaged or the reference temperature is set. Manual and automatic opening and closing louver device, characterized in that the manual opening and closing and angle adjustment of the shutter part is possible through the manual opening and closing part when not deformed as a reference.
delete delete delete According to claim 1,
The automatic opening and closing unit,
The shape memory alloy spring is contracted above the reference temperature to rotate the rotation lever in one direction so that the shutter part is opened,
A louver device capable of opening and closing manually and automatically, characterized in that the rotation lever is rotated in the other direction while the shape memory alloy spring is expanded by the elastic force of the return spring below the reference temperature so that the shutter unit is closed.
