It is possible to simply insert the hinge shaft 42 into the shaft insertion groove (53a) of the slider 53 to ensure the ease of installation and assembly work, as well as the window frame from the window frame outer frame (1b) When removing (2), by operating the operating lever 46 of the hinge shaft assembly 4 so that the hinge shaft 42 can be separated from the shaft insertion groove (53a) of the slider 53, the separation operation is also more It can be done easily.

Here, reference numeral 47 is a rubber stopper for blocking one side of the cylinder 43, 53b is a slide groove for avoiding the interference by the shank simultaneous shaft support (3a) of the slider 53, 6 is a bearing plate 7 is a spacer for preventing play between the support frame 41 and the slider 53.

Next will be described in detail with reference to the accompanying drawings the operation and operation of the present invention configured as described above.

First, when the power of the driving motor is transmitted to both side rotation support shafts P1 of the window frame intermediate frame 1a through the electric gear P2 of the window frame middle frame 1a, the rotation support shaft as shown in FIG. Rotational driving force is transmitted through the rotational driving support S1 of the window frame 2 connected to P1 so that both windows W of the middle frame 1a of the window frame are connected to the rotational driving support S1 and the window W. Opening and closing operation of the window (W) is performed by rotating the other side rotating support (S2) as a hinge axis.

At this time, the window (W) is rotated around the middle rotation support shaft (P1) of the window frame middle frame (1a) to open and smoothly inflow and outflow without blocking the flow of air, a plurality of windows with one drive source It is easy to install, assemble and operate with the structure of opening and closing.

In addition, in the present invention, the rotary support shaft (P1) and the shaft groove (3b) formed in the shaft support (3a) of the window frame 2 is condensed by the engagement by the polygonal square portion (3c) and the relative square portion (3d). By being able to rotate together to be able to combine the rotation drive function and the hinge function to rotatably support the window frame (2), thereby reducing the number of parts and simplify the device.

When the window frame 2 is axially coupled to the window frame outer frame 1b, the present invention uses the adjusting screw 44 and the operating lever 46 of the hinge shaft assembly 4 to rotate the hinge shaft 42. Draw out to the outside of the window frame (2) to be inserted into the shaft insertion groove (53a) of the slider 53 installed in the window frame outer frame (1b), again using the adjustment screw 44 and the operating lever 46 The hinge shaft 42 is inserted into the window frame 2 so as to be separated from the shaft insertion groove 53a of the slider 53, and the slider 53 of the fixing bracket 5 is a transfer screw. The assembly of the window frame 2 with respect to the window frame frame 1 is easy to disassemble and move because it is movable up and down in accordance with the hinge shaft 42 by the rotation operation of 54.

On the other hand, Figure 9 and Figure 10 is another embodiment of the present invention, Figure 9 is a power transmission unit (P) including a rotation support shaft protruding to both sides of the window frame middle frame (1a), and the window frame middle frame (1a) Rotation drive support (S1) for rotatably connecting and supporting between and the window (W) and rotation support (S2) for rotatably connecting and supporting between the window (W) and the window frame outer frame (1b) Window rotation support (S) is formed on the upper side of the window frame frame (1) to open the window (W) to the upper side, when opening the window frame (2) enters the inside of the window frame frame (1) window frame frame ( Since the space part is not formed between 1) and the window frame 2, the penetration of rainwater can be prevented.

10 shows a window rotation support part S formed of the power transmission part P, the rotation driving support part S1, and the rotation support part S2 is formed on the lower side of the window frame frame 1 so that the window W is lowered. As an open structure, it is advantageous when inflowing and outflowing air to the upper side of the window.

As described above, the present invention prevents the window from blocking the flow of air when the window is opened, and the window can be opened and closed without installing a driving means for opening and closing the window for each window, and noise is not generated in the movable part during the opening and closing of the window. In addition, assembling, disassembling and manipulating the window frame frame and the window frame by shaft coupling is easy, and the installation and operation cost is low, and when opening, the space part is not formed between the window frame and the window frame frame. It is possible to prevent the damage and damage of the machinery inside the factory.
