Description

[Detailed Description of the Invention] [Purpose of the Invention] "Industrial Application Field" This invention relates to a window opening/closing device, particularly a sliding window or a louver window having a sliding function.

"Prior Art" FIGS. 6 and 7 are vertical cross-sectional views of the awning window described in U.S. Pat. No. 3,197,818 in the interior and exterior directions, and FIG. , FIG. 7 shows the closed state.

When the handle H is rotated from the opening position of the shoji 3 in the window closing direction, the worm wheel 28 rotates via a worm (not shown), and this rotation is guided to the vertical frame 2 of the opening frame so as to be vertically movable via a link mechanism. 6. Raise the interlocking rod 6. Due to the rise, the shoji mounting arm 8, which is pivotally connected to the interlocking rod 6 by the pin 9, rotates along with the shoji 3 in the window closing direction about the pin 9,
A support link 13 supporting the shoji 3 rotates around a pin key 15 pivotally attached to a key grooved hole of a support block 14 fixed to the vertical frame 2. Here, the pin key 15 is formed by forming a cylindrical shaft with a width across flats,
The width across flats and the width of the keyway of the support block 14 are formed to have approximately the same dimension. And shoji 3 is the 6th
When the position shown in the figure is reached, the engaging part 8 of the shoji mounting arm 8
a comes into contact with a protrusion 42 fixed to the vertical frame 2, is guided by the protrusion 4, wraps around in the window closing direction, and closes the support link 1.
The width across flats part of the pin key 15 of 3 is the support block 1
Reach the position that matches the keyway of the keyway hole in step 4. Due to the alignment of the width across flats of the pin key 15 with the key groove, the movement of the support link 13 changes from rotation to upward movement, and this upward movement causes the lower stile 22b of the shoji 3 to move against the puller fixed to the vertical frame 2. It engages with the puller 21 and is pulled towards the indoor side.

``Problem that the invention seeks to solve'' The above-mentioned conventional example is useful for window opening and closing operations, especially for windows with narrow window frames that have been widely used in recent years (previously 70
mm wide ones were used, but in recent years 58 mm wide ones have started to be used. ) When the opening/closing operation of the shoji 3 was performed, the lower stile 22b of the shoji 3 did not properly engage with the pulling tool 21, and there were often cases where the sliding door was not pulled. The reason for this is that the engaging portion 8 of the shoji mounting arm 8 is caused by the vertically upward displacement of the interlocking rod 6.
a is displaced upward and hits the projecting piece 42, which generates an inward biasing force;
Because the distance between Due to the force acting on the side, the width across flats of the pin key 15, and the play between the keyway of the keyway hole of the support block 14, the lower stile 22b of the shoji 3 moves toward the puller 21.
This is because the shoji 3 begins to rise before it reaches a position where it can be engaged with the shoji 3.

The purpose of this invention is to solve the drawbacks of the above-mentioned conventional examples, and to provide an opening/closing device for windows (particularly windows with narrow window frames) that can be opened and closed smoothly and completely and does not rattle even when exposed to wind. do.

``Structure of the invention'' ``Means for solving the problem'' In this invention, a sliding door is attached to an interlocking rod that is movably guided by a drive device into grooves formed along the vertical frame of a window frame. A shoji mounting arm fixed to the upper part of the stile is rotatably attached around the pin via a guide piece, and the stile has a protruding pin below the pivot point of the shoji mounting arm. One end of the shoji support link is attached to the pin so as to be rotatable around the pin, and one end of the shoji support link is pivotally attached to the pin, and the other end of the shoji support link has an arcuate portion and two sides. A pin key having a width part is fixed, and the shoji support link is attached to a support block having a key groove above the center of the round hole part in a round hole part fixed to the vertical frame, and the pin key is attached to the support block when opening and closing the shoji. - The width across flats part of the key can be engaged and disengaged from the key groove to move up and down, and the arc part of the pin key can be engaged with the round hole part to be rotatably connected, and the shoji In the closed position, a protruding pin installed on the vertical stile of the shoji engages with a protruding piece fixed to the vertical frame, and the protruding pin is fixed to the window frame by a pin key fixed to the shoji support link. The support block engages with the key groove of the supported block, moves upward along the key groove, moves upward along the projecting piece, is pressed in the shoji closing direction, locks the shoji, and closes the shoji. This window opening/closing device is configured such that a hook fixed to a vertical stile engages a pulling tool fixed to the vertical frame to pull the shoji toward the window frame.

"Operation" When the interlocking rod is raised by the drive device from the state where the window is open, the shoji mounting arm rotates inward along with the shoji around the side that is pivotally connected to the interlocking rod. Rise. However, since the lower end of the shoji support link rotates at a predetermined position on the vertical frame side, the protruding pin rotates in an arc centered on the base side of the shoji support link until it reaches the position directly below where it can engage with the protrusion attached to the vertical frame. Get into it. At the same time, the base of the shoji support link can be raised. As the interlocking rod subsequently rises, the projecting pin engages with a projecting piece provided on the vertical frame and is pressed in the window closing direction, and the shoji support link moves in parallel, rises, and is locked. At the same time, the shoji rises, so the lower part of the shoji engages with the pulling tool, and the shoji is pulled.

"Example" Hereinafter, an example of this invention will be described with reference to the drawings.

Figure 1 is a vertical cross-sectional view in the internal and external direction, and Figure 2 is a partial cross-sectional view taken along A-A in Figure 1, including an enlarged cross-section taken along A'-A' in Figure 1.

The shoji mounting arm 8 is rotatable around the pin 9. The tip of the shoji mounting arm 8 is fixed in contact with the vertical stile 4 of the shoji 3.

It is fixed to the shoji mounting arm 8 at a position sufficiently far from the upper stile 11 side of the shoji 3 in the middle of the stile 4 of the shoji, for example, at a position where the length of the stile 4 is roughly divided into thirds is taken from the upper stile 11 side. The other end of the shoji support link 13 is rotatably attached to a projecting pin 12 provided therein, and the other end is fixed with a machine screw 16 to a pin key 15 fitted into a support block 14 fixed to the vertical frame 2. There is. The support block 14 is provided with a keyway 14b above the center of the round hole 14a. As shown in FIG. 1, the pin key 15 is a cylinder having a diameter that fits smoothly into the round hole 14a of the support block, and both sides of the cylinder are removed and the remaining arcuate portion 15a and the two remaining circular parts 15a fit smoothly into the key groove 14b of the support block. A surface width portion 15b is provided. The angle at which the pin key 15 is attached to the shoji support link 13 is such that the pin key 15 slides into the keyway 14b of the support block at the inclination angle of the shoji support link 13 when the shoji 3 is closed.

A groove 1 provided adjacent to the aforementioned groove 5 of the vertical frame 2
A base portion of a projecting piece 18 is accommodated in the inside of the vertical frame 2, and a small screw 19 passing through the base portion is screwed into the vertical frame 2.
The aforementioned protruding pin 12 for pivotally supporting one end of the shoji support link 13 to the shoji 3 and the protruding piece 18 protrude from each other so as to overlap in the facing direction. Projection piece 1
Reference numeral 8 includes an oblique introduction part 18a through which the protrusion pin 12 is guided inward, and a vertical guide part 18b through which the protrusion pin 12 is guided vertically upward following the introduction part 18a. The introduction part 18a is approximately the support block 1
It is located on a radius centered on the round hole portion 14a of No. 4.

4 and 5 are perspective views of the lower part of the shoji 3 pulling means. A pulling tool 21 that pulls the lower part of the shoji 3 when the shoji 3 is closed is fixed to the vertical frame 2. A pulling tool 21 is located near the bottom end of the vertical stile 4 of the shoji 3.
A hook 22 is fixed which engages with. The pulling tool 21 has a pulling cam portion 21a, and a hook 22
One side of the tip portion 22a of the cam portion 21a engages with the cam portion 21a.

The drive device 23 for the interlocking rod 6 will be described. A worm 26 provided on an operating shaft 25 supported by a main body 24 of the drive device fixed to the inner member of the vertical frame 2 is engaged with a worm wheel 28 rotatably attached to a shaft 27 fixed to the main body 24. . Worm foil 28 has arms 29 . One end of the large link 34 is rotatably attached to a pin portion 33 of a crank arm 32 which is provided at the bottom of the vertical frame 2 so as to be swingable by a shaft 31. 35, it is rotatably attached. The lower part of the large link 34 and the end of the worm wheel arm 29 connect both ends of the small link 36 to the pin 3.
7 and 38, they are pivotally connected.

Next, the effect will be explained. When the shoji 3 is closed, the interlocking rod 6 is at its upper limit of movement, and the pin key 15 fixed to the lower end of the support link 13 enters the keyway 14b of the support block 14 so as to end there. . In the upper part of the shoji 3, the protruding pins 12 on the side of the vertical stile 4 of the shoji 3 touch the inside of the vertical guide part 18b of the protrusion 18, and the shoji 3
At the lower part of the shoji, a tip 22a of a hook 22 fixed to the shoji frame 2 engages with a pulling tool 21 fixed to the vertical frame 2 of the window frame. , forming a means for pulling the shoji there. Each part of the drive device 23 is located at the position shown by solid lines and dotted lines in the figure.

The operation of opening the shoji 3 is as follows. When the operating shaft 25 is rotated by a handle (not shown) attached to the operating shaft 25, the worm 26 is rotated.
The rotation is decelerated and transmitted to the worm wheel 28. The arm 29 of the worm wheel rotates counterclockwise in FIG. 1 about the axis 27 (hereinafter the same). The arm 29 pushes the small link 36 to the left,
While rotating, it moves to the left and pushes the lower part of the large link 34 to the left. Since the lower part of the large link 34 moves to the left, the crank arm 32 rotates counterclockwise around the shaft 31, and the lower end of the large link 34 moves to the left.
It rotates clockwise around the pin part 33 of No. 2, and also rotates clockwise around the pin 35. As a result, the shaft 31 and the pin 35 are brought closer to each other, so that the guide piece 7 to which the pin 35 is attached is guided by the guide groove 5 and moves downward.

When the guide piece 7 moves downward, the pin 9 at the base of the shoji mounting arm 8 moves downward. At this time, the protrusion pin 12 attached to the shoji mounting arm 8 is moved vertically downward by the vertical guide portion 18b of the protrusion 18 attached to the vertical frame 2, so that the upper end of the shoji support link 13 is also directed vertically upward. The shoji support link 13 is thereby pushed downward, and the pin key 15 fixed to its lower end is guided by the keyway 14b of the support block 14 and directed vertically downward. Then, the protruding pin 12 is inserted at the corner of the vertical guide part 18b and the introduction part 18a of the protruding piece 18 at a position where the protruding pin 12 can escape outward.
The key 15 escapes from the key groove 14b of the support block 14, and the circular arc portion 15a of the pin key 15 comes into contact with the round hole portion 14a, and the pin key 15 becomes rotatable in the round hole portion 14a.

Along with the above operation, the shoji mounting arm 8 moves the guide piece 7
As the shoji 3 also descends, the shoji 3 begins to slide downward. Then, the tip portion 22a of the hook 22 attached to the lower part of the shoji 3 is removed from the pulling tool 21.

When the operating shaft 25 is further rotated in the same direction and the guide piece 7 is lowered further, the pin 9 attached to the guide piece 7 is further lowered and the force is transmitted to the protruding pin 12, so that the shoji support link 13 is attached to the pin key at the lower end. 15 rotates counterclockwise through the round hole 14a of the support block 14, the pin key 15 rotates counterclockwise around the pin key 15, and the protruding pin 12 separates from the protruding piece 18. At the same time, the shoji mounting arm 8 rotates toward the outside around the pin 9 at its base and further descends, so that the shoji 3
As it slides downward, it opens with the lower side facing the outside around the pin 9, resulting in the state shown by the two-dot chain line in FIG.

The operation of closing the shoji 3 from the open state is as follows. When the operating shaft 25 is rotated in the opposite direction, the worm 26 is reversed and the worm wheel 2
8 rotates clockwise around the shaft 27, the arm 29 rotates in the same direction, and the small link 36 pulls the lower part of the large link 34 inward. Since the large link 34 rotates counterclockwise around the pin 35 and the crank arm 32 rotates clockwise around the shaft 31, the distance between the shaft 31 and the pin 35 moves away. As a result, the guide piece 7 is guided by the guide groove 5 and rises.

The pin 9 rises, the shoji mounting arm 8 rotates counterclockwise around the pin 9, and the shoji support link 13 rotates clockwise around the round hole 14a of the support block 14, and the shoji 3 rises. Meanwhile, it begins to close by rotating counterclockwise around pin 9 so that the lower end faces inward. The protruding pin 12 is the protruding piece 1
Support block 14 along the lower surface of introduction part 18a of 8
It draws an arc centered on the round hole 14a and goes around to the inside. When the protruding pin reaches a position where the vertical guide part 18b of the protruding piece 18 can slide and the vertical guide part 18b intersects the introduction part 18a, the width across flats of the pin key 15 fixed to the lower end of the shoji support link 13 is reached. The portion 15b has been rotated to a position where it can enter the keyway 14b of the support block 14. On the other hand, in this position, the shoji mounting arm 8 and the shoji support link 13 stop rotating, and the shoji 3 is in a substantially vertical posture. In this position, the tip end 22a of the hook 22 provided at the lower part of the shoji 3 is spaced downward from the pulling tool 21 at a position in the internal and external direction where it can engage with the cam portion 21a of the pulling tool 21.

When the operating shaft 25 is further rotated in the same direction as above, the guide piece 7 further rises, and the protrusion pin 12 of the shoji mounting arm 8 is guided by the vertical guide part 18b of the protrusion piece 18 and cannot move to the outside. The shoji support link 13 rises vertically and the protruding pin 12 rises vertically at the upper end and the pin key 15 at the lower end.
is fitted into the keyway 14b of the support block 14, thereby moving in parallel and rising.

As a result, the shoji 3 rises, and the upper part of the shoji is locked by the engagement between the protrusion pin 12 and the protrusion 18, and the lower part of the shoji is locked by the tip 22 of the hook part 22.
a engages with the cam portion 21a of the puller 21 and is pulled inward, and the shoji 3 presses against an airtight gasket (not shown) provided on the opening frame 1.

When the shoji 3 is closed, the drive device 23
Therefore, the guide piece 7 is immovable and the pin 9 is immovable. Shoji mounting arm 8 and shoji support link 1
Since 3 is at an angle close to 180 degrees, if left as is, shoji 3 will wobble when exposed to strong winds. Therefore, the protruding pin 12 cannot be moved to the outside by the protruding piece 18, and since the puller 21 and the hook 22 are connected at the lower part, the shoji 3 will not be blown by the wind.

[Effect of idea]

This invention has the following excellent effects.

(1) Movement is smooth. That is, since the projecting pin is provided at the pivot point between the vertical stile and the shoji support link, the force acting on the shoji in the direction of closing the shoji due to the shoji support link and the force acting on the shoji in the direction of closing the shoji due to the engagement between the projecting pin and the protruding piece. Since the force acts on the same point, the shoji window can be closed reliably.

(2) Furthermore, since the distance between the pin that pivotally connects the shoji and the interlocking rod and the protruding pin is long, a large force is applied in the direction of closing the window due to the engagement between the protruding pin and the protruding piece.

(3) When the shoji is closed and the protruding pins and hooks are supported by the protrusions and pullers, the protrusions and pullers stop the shoji from moving inward and outward, preventing it from being blown by the wind. I don't do it often.

(4) One end of the shoji support link is pivotally connected to a protruding pin, and a pin key having an arc portion and a width across flats portion is fixed to the other end of the shoji support link. A supporting block having a hole and a keyway above the center of the round hole is provided with a support block that is capable of moving up and down by engaging and disengaging the width across flats of the pin key with the keyway when opening and closing the shoji screen. Since the circular arc part of the key is engaged with the round hole part and is rotatably connected, when the window is closed, the connecting part between the shoji support link and the interlocking rod becomes a rigid joint, and the lock by this rigid joint supports the shoji. The links, interlocking rods, and shoji mounting arms are rigid triangular links, and the protruding pins that pivotally connect the shoji supporting links and the shoji mounting arms engage with protruding pieces fixed to the vertical frame. Therefore, the rigid triangular links are not allowed to move their protruding pins to the outside of the shoji due to the protruding pieces, so the upper part of the shoji is firmly fixed and is not blown by the wind at all.
