Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail. In addition, the same code | symbol is attached | subjected about the structure similar to the past among the structure of this invention.

In the accompanying drawings, FIG. 1 shows a lift sliding window according to the present invention, and FIG. 2 shows an automatic and manual switching device of the lift sliding window.

1 and 2, the window 100 is provided with a window 100 from the window frame 120 according to the operation rod 12 moved up and down by the motor 104, and the operation rod 12. Lift member 110 is provided for lifting. The automatic and manual switching device 200 of the lift sliding window 200 is connected to the working rod 12 on one side and the rod on the side of the lift member 110.

On the other hand, the detailed description of the configuration as in the prior art will be omitted.

Automatic and manual switching device 200 of the lift sliding window according to the present invention comprises a plurality of gears (230,240,250,260,270) in the interior of the housing (210,220). The first rack gear 230 is connected to the operation rod 12. That is, the plurality of protrusions 234 provided to the first rack gear 230 are respectively coupled to the plurality of grooves of the operating rod 12 provided correspondingly. The first pinion 240 meshes with the first rack gear 230. The second pinion 250 is disposed in parallel with the first pinion 240, and the second pinion 250 is combined with the first pinion 240 to be integrated with or separated from the first pinion 240 by an external force. Can be.

Looking at the coupling structure of the first pinion 240 and the second pinion 250, the first pinion 240 is provided with a shaft hole 242 passing through the central axis, the second pinion 250 is provided with a first pinion 240 The shaft 252 accommodated in the shaft hole 242 of the () is projected from the central axis, so that the first pinion 240 and the second pinion 250 is axially coupled. In this case, the shaft hole 242 of the first pinion 240 and the shaft 252 of the second pinion 250 may have a polygonal cross section, and thus may be integrally coupled to each other even when rotating.

The third pinion 260 meshes with the second pinion 250. Since the third pinion 260 must always mesh with the second pinion 250, its tooth width has the width of the tooth width of the second pinion 250 plus the length of the protruding axis 252. The second rack gear 270 is engaged with the third pinion 260, and the second rack gear 270 is connected with the lift member 110. That is, the plurality of protrusions provided on the second rack gear 270 are respectively coupled to the plurality of grooves of the lift member 110 provided correspondingly. An elastic member 280 is provided to elastically support the second pinion 250 with respect to the first pinion 240.

Meanwhile, reference numerals 232, 244, 254, 264, and 272 denote teeth of the gears 230, 240, 250, 260, and 270, and 262 denotes a central axis of the third pinion 260.

3 and 4, the state of use of the automatic and manual switching device of the lift sliding window is shown in cross section.

3 shows an automatic use state of the automatic and manual switching device 200 of the lift sliding window, that is, a case in which the working rod 12 lifts the lift member 110 by the motor 104. In this case, the first pinion 240 and the second pinion 250 are coupled to each other to maintain an integrated state. Thus, when the first rack gear 230 moves in accordance with the operation of the operation rod 12, the first pinion 240 and the second pinion 250 rotate integrally, and the first pinion 250 engages with the second pinion 250. 3 pinion 260 rotates. Accordingly, the second rack gear 270 moves to lift the lift member 110.

4 illustrates a manual use state of lifting the lift member 110 by coupling the handle 300 to the automatic and manual switching device 200 of the lift sliding window when the motor 104 does not operate. In this case, the handle 300 is selectively coupled to the second pinion 250. A receiving groove 256 is provided in the shaft 252 of the second pinion 250, and the handle 300 is connected to the receiving shaft 320 of the receiving groove 256 of the shaft 252 of the second pinion 250. ) Is provided, the second pinion 250 is axially coupled with the handle 300. At this time, the connecting shaft 320 of the handle 300 is greater than the sum of the length of the shaft hole 242 of the first pinion 240 and the depth of the receiving groove 256 of the shaft 252 of the second pinion 250. Having a length, the second pinion 250 can be separated from the first pinion 240.

On the other hand, the receiving groove 256 of the shaft 252 of the second pinion 250 and the connecting shaft 320 of the handle 300 has a polygonal cross section, thereby maintaining a state of being integrally coupled to each other even when rotating. Can be.

When the handle 300 is coupled to the second pinion 250, the second pinion 250 is separated from the first pinion 240 to become an independent entity. Thus, as the handle 300 is rotated, the second pinion 250 rotates, and the third pinion 260 meshed with the second pinion 250 rotates. Accordingly, the second rack gear 270 moves to lift the lift member 110.

Hereinafter, the operation of the present invention will be described with reference to FIGS. 1 to 4 again.

When the lift sliding window is automatically lifted, the operation rod 12 is moved up and down in accordance with the operation of the motor 104. Then, the first rack gear 230 coupled to the operation rod 12 is moved, and the first pinion 240 engaged with the first rack gear 230 rotates. In this case, the first pinion 240 and the second pinion 250 are integrally rotated in a coupled state, such that the third pinion 260 engaged with the second pinion 250 rotates. Then, the second rack gear 270 engaged with the third pinion 260 moves to operate the lift member 110. As such, the lift member 110 may be automatically lifted in accordance with the operation of the operation rod 12 by the motor 104.

On the other hand, when the motor 104 is not operated by a failure or the like, when the user wants to lift the lift sliding window manually, the lift member 110 is operated using the handle 300.

That is, the handle 300 is coupled to the second pinion 250 to manually rotate the second pinion 250 to operate the third pinion 260 and the second rack gear 270 to lift the member 110. To work. In this case, the second pinion 250 may be independently rotated by the handle 300 to be separated from the first pinion 240, and when the handle 300 is released, the position of the second pinion 250 may be changed by the elastic member 280. It may be restored and re-coupled to the first pinion 240.

As described above, according to the present invention, the window can be automatically lifted by the motor, and when the motor breaks down, the window can be manually lifted through the handle, thereby providing convenience in use.

In the above, preferred embodiments of the present invention have been described, but those skilled in the art to which the present invention belongs without departing from the technical scope of the present invention changes and modifications belong to the scope of the present invention Of course.
