Further, as shown in FIG. 5, a stepped pin 16 protrudes from the upper surface of the free end 21 b of the first swing arm 21, and the stepped pin 16 is placed in the long hole 19 of the second swing arm 22. By inserting the mounting screw 17 into the screw hole 16A of the stepped pin 16 from the upper side of the through hole 23A of the base end 23a of the slide arm 23, the stepped pin 16 that is a vertical support shaft is inserted into the second pin. The free end 21b of the first swing arm 21 and the base end 23a of the slide arm 23 are pivotally connected in a state of being inserted into the long hole 19 of the swing arm 22, and these arms 21 and 23 are vertically supported (stepped). It becomes relatively swingable around the attached pin 16).
In this way, the vertical support shaft (stepped pin 16) that pivotally supports the free end 21 b of the first swing arm 21 and the base end 23 a of the slide arm 23 is inserted into the long hole 19 of the second swing arm 22. Therefore, the slide operation of the slide arm 23 with respect to the second swing arm 22 is stabilized, and the thickness of the first swing arm 21, the second swing arm 22, and the slide arm 23 as a whole can be reduced.

As shown in FIGS. 2 and 3, a shoji side metal fitting 6 is attached to the lower right side (the lower frame 4L and the right vertical frame 4S) of the shoji 4, and the shoji side metal fitting 6 has a long hole 6A extending in the left-right direction. Since it is formed, the slide arm 23 and the shoji side metal fitting 6 are connected by inserting the pin 18 which is an operating portion provided at the free end 23b of the slide arm 23 into the long hole 6A, and constitutes an opening / closing mechanism. When the pin 18 is moved in the horizontal plane by the arms 21, 22, and 23, the shoji 4 is operated by the pin 18 through the shoji side metal fitting 6.
That is, by rotating the operator handle 11 around the rotation axis A, the operation shaft 12 and the worm 13A rotate, so that the worm wheel 13B and the first swing arm 21 meshing with the worm 13A are rotated by the rotation axis B (pin 14). Since the second swing arm 22 and the slide arm 23 swing around the rotation axis C (pin 15) and the slide arm 23 slides along the second swing arm 22, the slide arm The pin 18 of the free end 23b of 23 moves in a horizontal plane. Therefore, as described above, the shoji 4 is operated by the pin 18 through the shoji-side metal fitting 6, and the shoji 4 is opened and closed.

According to such a configuration of the window opening / closing device 2, when the shoji 4 shown in FIG. 4A is closed, the free end 21 b of the first swing arm 21 and the base end 23 a of the slide arm 23 are pivotally supported. The stepped pin 16, which is a vertical axis, is located closest to the base end 22 a side of the second swing arm 22 in the long hole 19 of the second swing arm 22, that is, the second swing arm 22 The length from the base end 22a to the pin 18 of the free end 23b of the slide arm 23 is the shortest.
On the other hand, in the state where the shoji 4 shown in FIG. 4B is opened, the stepped pin 16 is at a position farthest from the base end 22a side of the second swing arm 22 in the long hole 19, That is, the length from the base end 22a of the second swing arm 22 to the pin 18 of the free end 23b of the slide arm 23 is the longest.
As described above, the length from the base end 22a of the second swing arm 22 to the pin 18 of the free end 23b of the slide arm 23 is expanded and contracted by the length L in FIG. 4B.
Therefore, the window opening / closing device 2 has a length from the base end 22a of the second swing arm 22 to the pin 18 of the free end 23b of the slide arm 23 when the shoji 4 is closed (see FIG. 4A). Since the opening / closing window 1 (width of the lower frame 3L and upper frame 3U) is narrow, it can be used by being attached to the lower frame 3L, and the shoji 4 is opened (see FIG. 4B). ), Since the length from the base end 22a of the second swing arm 22 to the pin 18 of the free end 23b of the slide arm 23 is long, the opening amount (opening angle of the shoji 4) can be made relatively large.

  In the opening / closing mechanism including the first swing arm 21, the second swing arm 22, and the slide arm 23 in the window opening / closing device 2 of the present invention, the configuration for swinging the first swing arm 21 is as described above. Although not limited to the configuration using the worm 13A and the worm wheel 13B, according to the configuration using the speed reduction mechanism by the worm 13A and the worm wheel 13B, the operator handle 11 is rotated by a simple and compact speed reduction mechanism. The shoji 4 can be opened and closed against the wind pressure while obtaining a large operating force with a small torque, and the shoji 4 is opened even if a gust of wind blows, for example, by using the self-lock of the worm 13A and the worm wheel 13B. Can be held.

Embodiment 2. FIG.
6 and 7 are explanatory views of a window opening / closing device according to Embodiment 2 of the present invention, FIG. 6 is a plan view, FIG. 7 is an exploded perspective view of an arm constituting the opening / closing mechanism, and FIG. a) shows a state in which the shoji is closed, and FIG. 6 (b) shows a state in which the shoji is opened. 6 and 7, the same reference numerals as those in FIGS. 4 and 5 of the first embodiment denote the same or corresponding parts, and the second embodiment differs from the first embodiment only in the configuration of the guide means. .

That is, in the second embodiment, the elongated hole 19 extending in the longitudinal direction of the second swing arm 22 is formed longer than the first embodiment and close to the free end 22b of the second swing arm 22. The slide arm 23 does not have the bent pieces 20 and 20, and the slide arm 23 has a pin 24 which is a vertical projecting piece projecting downward at an intermediate portion between the base end 23a and the free end 23b. It is attached.
Since the vertical projecting piece (pin 24) and the vertical support shaft (stepped pin 16) positioned in the longitudinal direction of the slide arm 23 are inserted into the long hole 19, these vertical support shafts (stepped pin 16). ) And the vertical protrusion (pin 24) constitute the guide means, and the slide arm 23 is supported to be slidable in the longitudinal direction with respect to the second swing arm 22.
Since the slide arm 23 and the second swing arm 22 move relatively in the longitudinal direction and the vertical protrusion only slides in the long hole 19, the vertical protrusion does not necessarily have an axis like the pin 24. The shape may be any shape as long as it is fitted in the long hole 19 and can slide in the long hole 19.

Similar to the configuration of the first embodiment, when the shoji 4 shown in FIG. 6A is closed, the stepped pin 16 and the pin 24 are connected to the second swing 19 in the long hole 19 of the second swing arm 22. At the position closest to the base end 22a side of the moving arm 22, that is, the length from the base end 22a of the second swing arm 22 to the pin 18 of the free end 23b of the slide arm 23 is the shortest.
On the other hand, when the shoji 4 shown in FIG. 6B is opened, the stepped pin 16 and the pin 24 are located farthest from the base end 22a side of the second swing arm 22 in the long hole 19. That is, the length from the base end 22a of the second swing arm 22 to the pin 18 of the free end 23b of the slide arm 23 is the longest.
Thus, also in the configuration of the second embodiment, the length from the base end 22a of the second swing arm 22 to the pin 18 of the free end 23b of the slide arm 23 is the length L in FIG. 6B. Since it expands and contracts, the same effects as those of the first embodiment are obtained.
Further, since the guide means can be configured by using the elongated hole 19 of the second swing arm 22 by simply providing the pin 24 on the slide arm 23, the guide means has a very simple configuration. Therefore, the cost can be reduced.

In the above description, the configuration in which the long hole 19 is formed in the second swing arm 22 has been described. However, the long hole 19 is not necessarily formed in the second swing arm 22. In other words, the long hole 19 is not formed in the second swing arm 22, and therefore there is no long hole, so that the vertical support for pivotally supporting the free end 21 b of the first swing arm 21 and the base end 23 a of the slide arm 23 is provided. Without inserting the shaft into the long hole, the free end 21b of the first swing arm 21 and the base end 23a of the slide arm 23 are pivotally connected, and the slide arm 23 is connected to the second swing arm 22 by the guide means. It is also possible to adopt a configuration that supports the slide in the longitudinal direction.
Moreover, although the case where the opening / closing window 1 capable of opening the shoji 4 attached to the window frame 3 to the outdoor side is a side sliding window has been described, the opening / closing window 1 may be a protruding window, a fall-down window, a single window or A vertical sliding window, a movable small slit window, or a small circle window may be used.
Furthermore, although the configuration in which the width of the opening / closing window 1 (the width of the lower frame 3L or the upper frame 3U) is described has been described, the window opening / closing device 2 is compared to the configuration in which the height of the opening / closing window 1 (the height of the vertical frame 3S) is low. May be used.
Furthermore, although the case where the bracket 7 of the window opening / closing device 2 is attached to the lower frame 3L has been described, depending on the configuration of the opening / closing window 1, the bracket 7 of the window opening / closing device 2 may be attached to the upper frame 3U or the vertical frame 3S. .
Further, even when the window opening / closing device 2 is applied to a configuration in which the width and height of the opening / closing window 1 are not narrow and low, it is preferable because the opening amount (opening angle of the shoji 4) can be increased. .
