[0004]

[Problems to be solved by the present invention] 1) The above-mentioned actual development 6
The window opening / closing device described in Japanese Patent Publication No. 0-188783,
It can be opened and closed easily and surely by pulling the rope, but it is configured so that the window frame is pushed open by the pressing action of the compression coil spring built in the operating rod. There is a drawback that the operating state is likely to be unbalanced and the opening of the window frame is likely to be partially uneven. Further, the compression coil spring is configured to hold the opening degree of the window frame constant by the pushing force and does not include a mechanical opening degree fixing mechanism. The window frame fluctuates as it expands and contracts, making it noisy. further,
To close the window frame, the closing rope must be pulled with a force stronger than the acting force of the compression coil spring built into the operating rod, which is a very laborious task. Also means
Although the compression coil spring of the operating rod is considerably strong in order to surely push open the heavy window frame, this spring action directly resists when the window frame is closed. Above all, the spring action increases proportionally as the window frame approaches the closed position,
Since the difficulty of the closing work increases, the closed state of the window frame tends to be unbalanced. Besides, the manufacturing cost is high because the operating rod and the coil spring for compression are used,
There is a problem in that the load is designed to be large corresponding to the resistance of the compression coil spring, and the window frame structure has high strength and rigidity and becomes expensive. 2) In the window opening / closing device described in Japanese Utility Model Laid-Open No. 64-49569, the drawbacks and problems described in 1) above have been solved. However, mechanically the operating state is still unstable, it is difficult to open the window frame smoothly when opening and closing, and when it is caught, or the force to lock it at the desired opening position while the window is opening is weak, it opens when gusts are received, There are problems, etc. Also,
The frictional resistance between the end portion of the support rod and the vertical column is unexpectedly large, and rust easily occurs there, so that the operation is heavy and the user's burden is heavy. Further, when the window frame is opened to the maximum opening, the support rod takes a substantially horizontal posture and acts as if it were a reversing bar to the window frame, and the closing operation due to the weight of the window frame becomes unsuccessful. There is a problem to be solved.

[0005]

As a means for solving the above-mentioned problems of the prior art, a window opening / closing device according to the present invention has one side of a window frame 1 as shown in a preferred embodiment in the drawings. In a single-opening window opening / closing device which is openably / closably supported by a window opening frame by a hinge, a) one end of a supporting rod 2 is rotatably connected to the window frame 1 and the other end of the supporting rod 2 is rotatable. Is connected to the drive frame body 3. b) The guide columns 5 of the drive frame body 3 are fixed in the vertical direction of the window opening frame 4, and the guide columns 5 are positioned in the vertical direction at a predetermined pitch.

As shown in FIG. 1, two vertical bars 20, 20 are attached to the window frame 1 in parallel to each other in the vertical direction at a position close to the center, and the two vertical bars 20, 20 are attached in parallel to each other. One end of each of the two support rods 2, 2 is rotatably connected by a shaft pin 21 (FIG. 2). The two support rods 2 are of equal length and are connected to the common position of each of the two vertical bars 20, 20 described above in a symmetrical arrangement. The other end of each support rod 2 is connected to both sides of a drive frame 3 that moves up and down along a guide column 5 that is perpendicular to the vertical direction. Guide post 5
Are firmly fixed in a vertical posture by brackets 23 and 24 fixed to the upper and lower sides of the window opening frame 4.
A grooved steel material is used for the guide column 5, and there are a large number of substantially semicircular positioning notches 6 at a pitch of, for example, about 4 cm in the vertical direction over almost the entire length of the surface orthogonal to the opening / closing direction of the window frame 1. Has been formed.

The latch 7 that engages and disengages upward and the latch 8 that disengages downward from the two different positioning notches 6 and 6 on the upper and lower sides of the guide column 5 are, as shown in FIG. It is formed and is rotatably supported by the drive frame 3 by a common shaft 17. Two latches 7,
8 rotates around a shaft 17 to engage and disengage from the positioning notch 6. The latch 7 that engages and disengages upward with respect to the positioning notch 6 is formed integrally with a stopper 14 that engages and disengages with the hook 13 of the window frame 1 (FIG. 5). The two latches 7,
A torsion coil spring 15 is wound around a shaft 17 of 8 (FIG. 2), and one end of the torsion coil spring 15 has one latch 7
And the other end is latched to the other latch 8 so that the two latches 7 and 8 have a strong spring action in the direction of locking the positioning notches 6 and 6 in the upward and downward postures. I always receive power. As long as the respective latches 7 and 8 are engaged with the positioning notches 6 and 6, the drive frame 3
Is firmly locked so that it cannot move upward or downward.

As shown in FIG. 3, the drive frame 3 has a guide column 5
One side (the surface on which the positioning notch 6 is formed) of the above 2
It is configured to be transmitted by the individual latches 7 and 8 and to be raised and lowered on the opposite side by the upper and lower two guide rollers 9 and 9. The front end of the window opening rope 10 is fixed to the through hole 25 of the latch 7 which is engaged with and disengaged from the positioning notch 6 upward. The opening rope 10 is arranged upward from the inner surface side of the latch 7 through the tip portion to the inside of the groove of the guide strut 5, and is wound around the pulley 11 attached to the bracket 23 that supports the upper end portion of the guide strut 5. It is U-turned and hangs down the outside of the guide column 5 sufficiently long (FIGS. 1 and 2). Therefore, when the pulling rope 10 is strongly pulled, the latch 7 is first rotated about the shaft 17 and pulled out from the positioning notch 6, the upward movement is unlocked, and the drive frame 3 can be moved upward. become. At the same time, the stopper 14 integrated with the rack 7 also rotates about the shaft 17 and the hook 13 of the window frame 1 is rotated.
Be pulled from. Therefore, the window frame 1 can be opened. As a result, when the opening rope 10 is continuously pulled, the drive frame body 3 moves upward and upward along the guide column 5, and the window frame 1 connected to the drive frame body 3 by the support rod 2.
Is pushed open.

When the pulling force of the opening rope 10 is released, the latch 7 is immediately locked by the action of the torsion coil spring 15 in the nearest positioning notch 6, and the upward movement of the drive frame 3 is locked. At the same time, the downward latch 8 is also moved to the nearest positioning notch 6 by the action force of the torsion coil spring 15.
The drive frame 3 is locked even when it is moved downward. Therefore, the window frame 1 connected to the drive frame body 3 by the support rod 2 is
It is firmly fixed at the opening position and does not sway in an unstable manner even if it receives a strong tilt due to a gust of wind.

The tip end of the window closing rope 12 is fixed to the hook 13 on the lower side of the window frame 1. The closing rope 12 passes through the guide roller 26 on the entry side and then the drive frame 3
