Hereinafter, the fixed blade coupling structure of the system louver of the present invention with reference to the accompanying drawings as follows.

The fixed blade coupling structure of the system louver according to the present invention is installed in parallel in the vertical direction between the vertical frame 41, as shown in Figure 4 to 8 to open and close the opening of the frame member 40 through rotation A plurality of opening and closing blades 30; A fixed blade 10 provided at an upper side and a lower side of the frame member 40; And a fixing bracket 20 provided in each of the vertical frame 40 to support an end of the fixing blade 10. The system is applied to a system louver including a predetermined size to the fixing bracket 20. An elastic coupling groove 25 is provided and a coupling protrusion 15 inserted into the elastic coupling groove 25 is provided at one side of the fixed blade 10 to slide the fixed blade 10 to the fixed bracket 20. When engaging, the coupling protrusion 15 is inserted into the elastic coupling groove 25 so that the fixing blade 10 is fixed to the fixing bracket 20.

Here, the fixing bracket 20 is formed of a synthetic resin material, a pair formed inclined in a state spaced apart at regular intervals so as to protrude from the blade coupling surface 21 and the elastic coupling groove 25 is formed at the lower end. A pair of guide ribs 22 formed on both sides of the blade engaging surface 21 in a width direction, each having a U-shaped elastic rib 26 provided with an elastic piece 26 ', and the blade coupling It includes a plurality of reinforcing ribs 23 formed on the rear surface of the surface (21). Accordingly, when the fixed blade 10 is coupled in a sliding manner, the fixed blade 10 is correctly moved without being shaken by the guide ribs 22 and is coupled to the fixed blade 10 by the reinforcing ribs 23. ) Durability is improved.

In addition, the fixed blade 10 is formed of an aluminum material, the opening is formed on one side and the other side of the pair of blade plates 11 and spaced apart at regular intervals to be connected to each other, and the opening and closing blades 30 Intermediate connecting plate 12 is formed on one surface of the portion that is connected to the blade plate 11 and the intermediate portion of the blade plate 11 and the coupling protrusion 15 is connected to each other ( 13). Here, the intermediate connecting plate 13 is preferably formed at both ends of the fixed blade 10 coupled to the fixed bracket 20 to reduce waste and reduce weight.

The coupling protrusion 15 is fitted to the fitting portion 15a inserted into the elastic coupling groove 25 and the fixed blade 10 is fixed from the fixing bracket 20 by being caught by the end of the elastic coupling groove 25. It is preferable that the locking portion 15b is formed at the end of the fitting portion 15a so as not to be separated. Accordingly, when the fixing blade 10 is coupled, the interval between the elastic pieces 26 'forming the elastic coupling groove 25 is widened by the fitting portion 15a, so that the fixing blade 10 is easily formed. After the fixing blade 10 is coupled, the fixing blade 10 is firmly coupled since the elastic piece 26 'is restored so that the locking portion 15b does not fall out. Of course, when the fixing blade 10 is to be separated, the fixing blade 10 is fixed to the fixing blade 10 by opening the gap between the elastic pieces 16 ′ so that the catching portion 15b can be pulled out. It can be easily separated from.

Referring to the installation and removal of the fixed blade in the fixed blade coupling structure of the system louver of the present invention configured as described above are as follows.

In the rectangular frame member 40 consisting of a pair of horizontal frames 42 and a pair of vertical frames 41, bracket fixing members 43 are respectively installed on the upper and lower ends of the inside of the vertical frame 41, and the The fixing bracket 20 is coupled to the bracket fixing member 43 to fix each. At this time, it is obvious that the fixing bracket 20 should be installed so that the blade engaging surface 21 formed with the guide rib 22 and the elastic rib 26 faces inward.

Subsequently, in order to couple the fixing blade 10 to the fixing bracket 20, the opening of the fixing blade 10 is in contact with the end of the fixing bracket 20, and the fixing blade 10 in the horizontal frame 42 direction. To push. At this time, the fixing blade 10 is slid without shaking due to the guide ribs 22 provided on both sides of the blade contact surface 21 of the fixing bracket 20. In addition, the fixing blade 15 is inserted into the elastic coupling groove 25 formed in the elastic rib 26 of the fixing bracket 20 by the coupling protrusion 15 provided on the intermediate connecting plate 13 of the fixing blade 10. 10 is coupled to the fixing bracket (20).

The coupling protrusion 15 is inserted into the elastic rib 26 and is inserted while opening the gap between the pair of elastic pieces 26 'forming the elastic coupling groove 25, and the elastic coupling groove 25 When the coupling protrusion 15 is completely inserted into the elastic piece 26 ', the gap is reduced while restoring the elastic piece 26' so that the engaging portion 15b of the coupling protrusion 15 is caught in the elastic coupling groove 25. Therefore, as long as the gap between the elastic pieces 26 'does not open, the fixed blade 10 is maintained in a state coupled to the fixed bracket 20.

In order to separate the fixing blade 10 from the fixing bracket 20, the opening and closing blade 30 must first be separated from the frame member 40 or the opening and closing blade 30 must be rotated in the opening direction. This is to prevent the interference by the opening and closing blades 30 when sliding the fixed blade 10 to the upper or lower side of the frame member 40.

When the fixing blade 10 is to be separated, the coupling protrusion 15 of the fixing blade 10 is opened by spreading the elastic piece 26 'of the elastic rib 26 forming the elastic coupling groove 25 to the outside. What is necessary is just to let it escape from the elastic coupling groove 25. In this state, when the fixing blade 10 is pulled out, the coupling protrusion 15 is separated from the elastic coupling groove 25 and the fixing blade 10 is separated from the fixing bracket 20. Therefore, it is possible to maintain the cleanliness by cleaning the foreign matter such as dust on the fixing blade 10 and the fixing bracket 20.

As described above and described with reference to some embodiments for illustrating the technical idea of the present invention, the present invention is not limited to the configuration and operation as described above, it deviates from the scope of the technical idea described in the specification It will be apparent to those skilled in the art that many modifications and variations can be made to the present invention without departing from the scope of the present invention. Therefore, all such appropriate changes and modifications and equivalents should be considered to be within the scope of the present invention.
