However, the present invention is not limited thereto, and the graphite 134 may be formed only on the contact surface of the slider 130 in contact with the rail 110. It is obvious that it can be formed. Such graphite 134 is a material used as a sliding material by its own characteristics and serves to reduce frictional resistance. Therefore, the slider 130 can be moved smoothly along the rail 110 even if a roller or the like, which is a moving aid used in the existing louver device, is not installed.

The rotating member 140 is coupled to the sunshade louver 10 through the rotating body 146 and the rotating body 146 formed to surround the torsion spring 141, the torsion spring 141, and the rotating body 146, and the rotating body ( 146 is provided with a rotating shaft 148 installed to rotate.

Torsion spring 141 is composed of a body portion 142 and the engaging portion 144, 143 extending in different directions on the top and bottom of the body portion 142. The locking portion 143 extending at the lower end of the body portion 142 is formed to be inserted into the locking groove 133 formed on the slider 130. That is, the engaging portions 143 and 144 extend in the lateral penetration direction of the rail 110. Therefore, the locking portion 144 extending on the upper end of the body portion 142 is formed in a different direction from the lower locking portion 143, for example, in the horizontal direction opposite to the lower locking portion 143.

This torsion spring 141 is inserted into the engaging groove 133 of the slider 130 by a portion of the lower end, preferably about 1/2.

Rotating body 146 is formed to surround the torsion spring 141. Preferably, the rotation body 146 surrounds the remaining portion of the torsion spring 141 partially inserted into the slider 130, and is installed on the slider 130 by the rotation shaft 148. At this time, the rotating shaft 148 is installed through the body 142 of the rotating body 146 and the torsion spring 141.

The rotating shaft 148 penetrates the rotating body 146 and is formed to have a sunshade louver 10 installed at a lower end thereof. At this time, the upper end of the rotating shaft 148 is formed to rotate with the rotating body 146. Thus, when the rotary body 146 rotates, the sunshade louver 10 installed on the rotary shaft 148 is rotated together.

The rotating member 140 is elastically biased continuously in one direction by the torsion spring 141. For example, the rotating member 140 is rotatably fixed to the slider 130 so as to be elastically biased in the direction in which the sunshade louver 10 is unfolded. That is, the torsion spring 141 is inserted into and fixed to the slider 130 to be elastically biased in the opposite direction in which the rotation body 146 is rotated.

The rotary bar 160 is installed on the rail 110 to rotate the rotary member 140 as described above.

Referring to FIG. 5, the rotation bar 160 is installed and fixed to the inner side of the end of the rail 110. Preferably, the rotation bar 160 is formed on the inner side of the end of the slider 130 in the unfolding direction is formed to abut the rotating body 146 wrapped around the upper locking portion 144 of the torsion spring 141.

Therefore, when the slider 130 in which the rotating member 140 is installed is moved in the unfolding direction, the rotating body 146 is rotated by the rotating bar 160 from the position in contact with the rotating bar 160. That is, the sunshade louver 10 is formed to have a predetermined angle inclination. At this time, each louver 10 preferably has an inclination of 0 degrees to 90 degrees. That is, the point body 146 rotated by the rotation bar 160 is rotated at a maximum of 90 degrees as shown in FIG. 6D. Therefore, the sunshade louver 10 which rotates together with the rotating body 146 covers the window (not shown) as a whole to block sunlight from entering the building. Similarly, when the louver 10 is moved in the folded direction, the rotating body 146 rotated by the rotation bar 160 is elastically biased by the torsion spring 141 installed therein to be in the original position.

On the other hand, the stopper 170 is further installed on the rail 110. The stopper 170 may be installed on one side or both sides of the rail 110. Preferably, the stopper 170 is installed in the bearing holder 114 of the rail 110.

The stopper 170 detects the pressure generated as the slider 130 is moved more than a predetermined distance and serves to block the movement of the slider 130. For example, the stopper 170 is preferably a pressure sensor 170, and is electrically connected to the controller 180 to stop the operation of the driving motor 121 according to a signal detected by the pressure sensor 170. . In addition, the pressure sensor 170 is installed not only in the direction in which the slider 130 is unfolded, but also in the folded direction to prevent overload of the driving motor 121 according to the maximum movement or more of the slider 130.

More specifically, the signal detected by the external sensor 181 is input to the controller 188. At this time, the signal detected by the external sensor 181 is preferably amplified and input to the controller 188. Amplifying the signal is because the signal value detected by the external sensor 181 is small.

The external sensor 181 is for detecting the state of the external environment, for example, to detect the amount of solar radiation, temperature, illuminance, and the like. The signals detected by detecting such various states are compared with the information of the pre-stored data storage unit 186 and output to the controller 188. Therefore, the driving motor 121 calculates the opening and closing state and the angle value of the louver 10 by the controller 188 based on the signal detected by the external sensor 181 according to the state value of the pre-stored data storage unit 186. Will be controlled. Preferably, the control unit 188 controls the moving state of the slider 130 received the rotational force from the drive motor 121 by controlling the rotational speed of the drive motor 121.

The louver device 100 operated by the external sensor 181 as described above automatically forms the optimum environmental condition by adjusting the opening and closing state of the louver 10.

Meanwhile, the switch signal 182 or the wireless remote signal 183 is configured to allow the user to arbitrarily adjust the louver 10 of the louver device 100, and the wireless remote signal 183 to wirelessly control the louver device 100. Receiver 184 is authorized to be installed. That is, the signal input value of the signal of the receiving unit 184 and the switch signal 182 to which the wireless remote signal 183 is applied are output to the controller 188 so that the controller 188 controls the driving motor 121.

The controller 188 controls the forward and reverse rotation of the driving motor 121 from the signal output from the input unit 185, and serves to turn on / off. In addition, the driving motor 121 may be forcibly turned off by receiving a signal detected from the pressure sensor (stopper) 170 installed in the rail 110. This is to prevent excessive overload of the driving motor 121.

As a result, the louver device 100 of the present invention by the controller 180 having the above structure automatically provides an optimized environment according to the environment, or the user can easily open and close the louver device 100 arbitrarily Make it quick.

The controller 180 may be connected to a central control computer 187 which is a central control device. That is, the plurality of louver devices 100 installed in the building are respectively connected to the computer 187 and controlled by the computer 187 as a whole. More specifically, the computer 187 connected by communication with the control unit 188 and the communication module 189 of the controller 180 is a signal input to each control unit 188, that is, detected by the external sensor 181 Signal is applied. The computer 187 receiving the signal calculates the collected data and outputs the signal to the controller 188 again. Accordingly, the controller 188 controls the driving motor 121 installed in each louver device 100 by outputting a signal calculated from the computer 187.

Such a configuration is for controlling a plurality of louver devices 100 installed in a building through one server (computer). The program is set in advance to control the louver 10 opening and closing state of the louver device 100 or This is to control the opening and closing state of the louver 10 in accordance with the situation of the external environment based on the stored data. On the other hand, as described above, it is obvious that the user can control the louver device 100 through the wired, wireless, 182, 183, respectively.
