SUMMARY OF THE INVENTION According to the present invention, there is provided a step opening / closing means for a sliding window with a sliding butterfly shaft, wherein the sliding butterfly shaft moves up and down in a rail to open and close the step window. The other end of the same number of arms as the windows in which the pins provided on the connecting rod which is transmitted to the chain wheel integrated with the screw shaft and which moves up and down in conjunction with the nut into the sliding holes are pivoted to the side surface of each window. The locking pin is provided at the lower part of the connecting rod, and the closing pin lock is generated when the stopper pin is fitted into the recess of the stopping fitting protruding from the lowermost sliding window.

[0006]

[Operation] Manual operation of the exposure handle (left)
When the wheel rotates, the guide chain (roller chain) together with the chain wheel below the handle rotates each chain wheel (left) integrated with the screw shaft with the left and right nuts, and pivots down on the nut to lower the nut by screw-and-pair motion. The stay is pulled down by pulling the connecting rod maintained by another guide. Then, since the pin provided on the connecting rod pulls down the arm rod with the sliding hole, the pivot hinge in the sliding window, that is, the sliding screw shaft, tilts the sliding window in the clockwise (reverse) rotation direction while rising in the rail. Just before that, the stop pin on the connecting rod side fits into the recess of the stop fitting protruding from the lower end of the sliding window immediately before the sliding window. To achieve. In such a case, the handle operation
Since the window suddenly stops moving, the closing is confirmed by a response. Next, when the handle is rotated (right) to open the window, first, the nut of the screw shaft is raised, and the connecting rod via the stay is also raised, so that the stop pin (lowest) provided on the connecting rod is , It floats up from the recess of the stop fitting on the window side and releases the window lock properly, but at the same time, the pins loosely inserted into the sliding holes of each arm rod pivotally attached to the side of the sliding window are also connected. As the rod rises, it will move upward along the sliding hole, but it will slide out until the stop pin of the connecting rod rises from the recess of the stop fitting on the window side and the lock is released. If the window is not slightly tilted and the pin is not allowed to move in the sliding hole of the arm rod, tilting the sliding window in the closed window lock state will not only damage the member but also open the window is dangerous and impossible. Therefore, a sliding hole is provided especially on the arm rod so that the fenestration starts after unlocking. One in which the. At the same time as the window opens, the sliding butterfly shaft descends on the rail and slides down while moving down the window. The fenestration ends because the torque limiter (not shown) is activated to put the handle in a no-load state.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic perspective view of a tuning opening / closing means of a step window with a sliding butterfly shaft according to an embodiment of the present invention. In the figure, a handle 1 is exposed at an accessible position on the indoor side of a lowermost sliding window W among step windows, and can be easily rotated by manual operation, and a chain is provided inside a lower panel (not shown). Car 2 is inside. On both the left and right wings, a helical shaft 6 integrating the chain wheels 3 and 4 is rotatably erected, and the chain wheels 2, 3, 4 are hung endlessly under the guiding condition 5 (roller chain). Then, when the steering wheel 1 is turned, each chain wheel rotates simultaneously in the same direction. The nut 7 is screwed onto the screw shaft 6, and when the screw shaft 6 is rotated (left) by a screw pair, the nut 7 linearly descends, so that the left and right connecting rods 9 also descend via the stay 8 which is pivotally mounted. The connecting rod 9 can be moved up and down freely by being held by a guide 10 fixed to the opening vertical frame H everywhere. Next, the same number of arm rods 11 as the windows pivotally connected to the side surfaces of the sliding window W with the pins 14 are formed with sliding holes 13 at the other ends, and the pins 9B provided on the connecting rod 9 side are loosely inserted and pivoted. Is being worn. The stop pin 9A provided below the connecting rod 9 forms a recess 12A at the end of the stop fitting 12 protruding below the lowermost window in the sliding window W, and the stop pin 9A is Can be inserted. A pivot hinge 15 (detailed illustration) is provided above the side surface of the sliding window W, and can slide up and down on a rail 16 (detailed illustration) attached to the opening vertical frame. It has the same form as the step window with sliding butterfly shaft. Since the lead of the screw shaft 6 and the nut 7 used in the present invention is a (right) screw, the nut which moves up and down by the screw pair moves down when the handle 1 is turned counterclockwise, and all the sliding windows W. On the other hand, if the steering wheel 1 is turned to the right, all the sliding windows W ... W are opened, so if one tries to change the relationship between the opening and closing of the window and the rotation of the steering wheel,
The screw 6 and the nut 7 may be screwed (left).
