Further, in the window sash according to the embodiment of the present invention, as shown in FIG. 2, in addition to the opening / closing mechanism including the slide shaft 55 and the rotating arm 3, the shoji 2 is provided below the slide rail 51 of the opening / closing mechanism. An impact absorbing means 6 for absorbing an impact at the time of opening and an opening / closing operation means 7 for opening / closing the shoji 2 are provided.
Hereinafter, each configuration of the embodiment of the present invention will be described in detail.

(Configuration of opening and closing mechanism)
The opening / closing mechanism of the window sash according to the embodiment of the present invention will be described with reference to FIG.
The slide rails 51 and 51 provided at the upper positions of the left and right vertical frames 13 and 14 are formed in a groove shape by wall portions projecting in the inner peripheral direction of the left and right vertical frames 13 and 14. 2 is guided in a vertical direction on a slide shaft 55 provided at a substantially central position in the estimated upper end direction. A roller portion 55a is rotatably supported at the tip of the slide shaft 55 guided in the slide rails 51 and 51.
The inner peripheral ends of the left and right wall portions are bent so as to be close to each other, thereby preventing the roller portion 55a of the slide shaft 55 guided in the slide rails 51, 51 from slipping out of the slide rails 51, 51.

The slide rails 51 and 51 include slide portions 51a and 51a arranged in parallel to the left and right vertical frames 13 and 14, and an inclined portion 51b that is continuously inclined above the slide portions 51a and 51a toward the indoor side. 51b. The upper ends of the inclined portions 51b and 51b are positioned approximately in the center in the prospective direction of the left and right vertical frames 13 and 14, and the slide portions 51a and 51a are outdoor in the prospective direction of the inner peripheral surfaces of the left and right vertical frames 13 and 14. Is arranged.
Since the inclined portions 51 b and 51 b are formed above the slide rails 51 and 51, when the shoji 2 is closed, the slide shaft 55 is pulled to the indoor side, and the upper rod 21 against the airtight material provided on the upper frame 11. Is pressed.

A vertical frame side support bracket 56 is installed on the inner peripheral surfaces of the left and right vertical frames 13 and 14 of the window frame 1, and one end of the rotary arm 3 can freely rotate on the inner peripheral surface of the vertical frame side support bracket 56. A first support shaft 31 is provided for supporting the first support shaft 31. At this time, the vertical position of the first support shaft 31 in the left and right vertical frames 13 and 14 is set to a height at which the center of gravity G of the shoji 2 faces when the shoji 2 is closed.
On the other hand, a shoji support bracket 57 is installed between the slide shaft 55 on the outer peripheral surface of the left and right vertical shafts 23 and 24 of the shoji 2 and the center of gravity G of the shoji 2, A second support shaft 32 that rotatably supports the other end of the rotary arm 3 is provided.
Between the first support shaft 31 and the second support shaft 32, there is provided a rotating arm 3 having a dimension a that is approximately ½ of the distance between the slide shaft 55 and the center of gravity G of the shoji. .
Further, a screw hole 56a for fixing the vertical frame side support bracket 56 to the left and right vertical frames 13 and 14, and a screw hole 57a for fixing the shoji support bracket 57 to the left and right vertical rods 23 and 24 are provided. The mounting positions of the vertical frame side support bracket 56 and the shoji support bracket 57 are configured so that fine adjustment (about 5 to 10 mm) can be performed.

The above-described slide shaft 55, slide rail 51, first support shaft 31, second support shaft 32, and rotating arm 3 constitute the window sash opening / closing mechanism of the present embodiment. By specifying the positional relationship as described above, it is possible to configure a window sash that is not affected by the gravity of the shoji 2 during opening and closing.
Hereinafter, the opening and closing of the window sash will be further described with reference to FIG.
In the closed state in FIG. 4, the shoji 2 is housed in the inner periphery of the window frame 1, and the opening is closed by the shoji 2. At this time, the vertical frame side support bracket 56 is located with respect to the left and right vertical frames 13 and 14 so that the first support shaft 31 is located at a portion of the left and right vertical frames 13 and 14 facing the center of gravity G of the shoji 2. Is fixed. In the closed state, the slide shaft 55 at the upper end of the shoji 2 is positioned in the inclined portions 51b and 51b of the slide rail 51, and the upper side of the shoji 2 is pressed to the indoor side, and the lower side of the shoji 2 is a pulling handle or the like. By operating, the space between the window frame 1 and the shoji 2 is hermetically sealed.

  When the lower side of the shoji 2 is pushed to the outdoor side from the closed state, the first support shaft 31 cannot move in the height direction with respect to the left and right vertical frames 13 and 14. Rotates while moving downward along the slide rails 51, 51 of the left and right vertical frames 13, 14, and moves the lower part of the shoji 2 to the outdoor side. At this time, since it moves toward the lower outdoor side along the inclined portions 51b and 51b in the upper part of the slide rail 51, the movement starts smoothly with respect to the force pushing the shoji 2 outward.

Further, when the lower side of the shoji 2 is pushed out to the outdoor side, the slide shafts 55 and 55 at the upper end of the shoji 2 move downward along the slide portions 51a and 51a of the slide rail 51, but the slide shaft 55 moves in the indoor / outdoor direction. 4 and the position of the first support shaft 31 is constant. Therefore, the center of gravity G of the shoji 2 with the slide shaft 55 as the rotation center is as shown in “the locus of the center of gravity G” in FIG. Without being displaced in the vertical direction, it is displaced almost straight in the outdoor direction toward the open state and the fully open state.
Thus, since the center of gravity G of the shoji 2 that opens and closes is not displaced in the vertical direction, there is no resistance due to the weight of the shoji 2 when the shoji 2 is opened and closed, and it opens and closes smoothly due to a slight natural wind or a difference in atmospheric pressure inside and outside the room. A rotary open / close ventilation window can be constructed.

As described above, in the present embodiment, the vertical displacement of the center of gravity G of the shoji 2 due to opening and closing is almost eliminated, and the shoji 2 can be opened and closed with a slight natural wind, etc., and no external force is applied. In shoji, the shoji 2 does not change its state. However, depending on the location where the window sash is installed, the shoji 2 is biased to a slightly closed state in a range that does not act as an opening / closing resistance of the shoji 2 under the condition that no external force is applied, and conversely, it is somewhat open. In some cases, it is preferable to be biased.
Therefore, the window sash according to the embodiment of the present invention is applied so that the gravity of the shoji 2 makes the shoji 2 closed when the shoji 2 is not applied with an external force, and on the contrary, it opens. In order to control such that the vertical frame side support bracket 56 that supports the first support shaft 31 and the shoji support bracket 57 that supports the second support shaft 32, the position adjustment means (formed in the long hole) Screw holes 56a, 57a) are provided, and the dimensions of the rotary arm 3 can be changed accordingly. In addition, the structure which can adjust the dimension of the said position adjustment means and the rotation arm 3 is not restricted to making the said screw hole into a long hole, What is necessary is just to employ | adopt a well-known structure.
Hereinafter, description will be made with reference to FIG.

In the opening / closing mechanism shown in FIG. 5A, the fixing position is set by position adjusting means (screw holes 56a and 57a formed in the long holes) provided in the fixing portion of the first support shaft 31 or the second support shaft 32. By adjusting, the length of the rotary arm 3 is set to be larger than the distance a from the slide shaft 55 to the second support shaft 32 by b. Therefore, as the shoji 2 is opened, the position of the center of gravity of the shoji 2 is increased, and in the opened state, a force in the closing direction due to the weight of the shoji 2 is applied.
In order to set the length of the rotary arm 3 larger than the distance a from the slide shaft 55 to the second support shaft 32, the position of the first support shaft 31 is adjusted and the dimensions of the rotary arm 3 are changed. Even if it goes, it is possible by either adjusting the position of the second support shaft 32 or changing the dimensions of the rotary arm 3. In FIG. 5A, the center of gravity of the shoji 2 in the former case is denoted as g, and the center of gravity of the shoji 2 in the latter case is denoted as G.
The window sash set as above is exhausted by opening the window when the atmospheric pressure in the building becomes high, etc., but after the air pressure in the building is exhausted, the pressure difference disappears. The open window will naturally close without maintaining the open state.

On the other hand, in the opening / closing mechanism shown in FIG. 5B, the length of the rotary arm 3 is set to be smaller than the distance a from the slide shaft 55 to the second support shaft 32 by b. Therefore, as the shoji 2 is opened, the position of the center of gravity G of the shoji becomes lower. Therefore, in the open state, a force in the opening direction due to the weight of the shoji 2 is applied.
As in the example of FIG. 5A, in order to set the length of the rotary arm 3 to be smaller than the distance a from the slide shaft 55 to the second support shaft 32, the first support shaft 31 is used. Even if the position of the second support shaft 32 is changed and the size of the rotary arm 3 is changed, the position of the second support shaft 32 and the size of the rotary arm 3 can be changed. In FIG. 5B, the center of gravity of the shoji 2 in the former case is denoted as g, and the center of gravity of the shoji 2 in the latter case is denoted as G.
And the window sash set as described above closes the window to prevent the intrusion of outside air when the wind hits the window of the building, etc. It can be opened with a small external force to exhaust the air in the building.
In the present embodiment, in order to adjust the center of gravity of the shoji, a weight or the like can be arranged inside the upper and lower saddle frames of the shoji so that the position of the center of gravity of the shoji can be set accurately.

(Configuration of shock absorbing means)
The shock absorbing means will be described with reference to FIG.
The shock absorbing means 6 includes a shock absorbing block 61 that contacts the slide shaft 55 that has moved downward in the slide rail 51 as the shoji 2 is opened, and a shock absorbing shaft 62 that is coupled to the lower side of the shock absorbing block 61. A shock absorbing shaft guide 63 that guides the movement of the shock absorbing shaft 62 in the vertical direction, a coil spring stopper 62a fixed at an upper position of the shock absorbing shaft 62, and a stopper 62b fixed to the lower end of the shock absorbing shaft 62. The coil spring 64 is disposed between the shock absorbing shaft guide 63 and the coil spring 64.
When the slide shaft 55 of the shoji 2 is not in contact with the shock absorbing block 61, the shock absorbing shaft 62 is stopped by the stopper 62b by the repulsive force of the coil spring 64 disposed between the shock absorbing shaft guide 63 and the coil spring stopper 62a. Is located at the upper end position in contact with the lower surface of the shock absorbing shaft guide 63. From this state, the shoji 2 is opened, and when the slide shafts 55, 55 move downward along the slide rails 51, 51 and come into contact with the shock absorbing block 61 from above, the coil spring 64 contracts to open the shoji 2. The shock of is absorbed.
When the shoji 2 is closed, the restoring force of the coil spring 64 urges the shoji 2 in the closing direction to assist the operator in closing the shoji 2.
As described above, the shock absorbing means 6 absorbs the shock when the shoji 2 is opened and prevents the slide shaft 55 from coming off from the lower end of the slide rail 51. Further, the size of the coil spring 64 is reduced. It also has a function as a means for setting the full opening angle of the shoji 2 by selecting or providing a means for setting the moving lower end position of the shock absorbing block 61.

(Configuration of opening / closing operation means)
The opening / closing operation means of the embodiment of the present invention will be described with reference to the opening / closing operation means arranged in the left vertical frame 13 of FIG. The configuration of the opening / closing operation means arranged in the right vertical frame 14 is substantially the same as that arranged in the left vertical frame 13.
The opening / closing operation means 7 is provided in the vicinity of the first support shaft 31, and is provided with an operation member 71 arranged on the inner peripheral surface of the left vertical frame 13 so as to be movable up and down, and an opening / closing operation provided on the outer peripheral surface of the rotary arm 3. The pin 72 is comprised.

The operation member 71 disposed on the inner peripheral surface of the left vertical frame 13 includes an upper rib 711 provided at an upper position of the operation member 71, a lower rib 712 provided at a lower position of the operation member 71, an upper rib 711, and a lower portion. The connecting portion 713 is connected to the rib 712, and the connecting portion 713 is fixed to an operating rod 74 disposed along the guide rail 73 formed on the inner peripheral surface of the left vertical frame 13.
The operating member 71 moves up and down on the inner peripheral surface of the left vertical frame 13 by moving the operating rod 74 up and down along the guide rail 73 by operating means such as a manual handle or an electric actuator operated by the operator. It is configured as follows.
The upper rib 711 of the operation member 71 has an upper rib inclined portion 711a inclined upward from the indoor side toward the outdoor side, and an upper rib vertical portion 711b extending vertically upward from the outdoor end of the upper rib inclined portion 711a. The lower rib 712 includes a lower rib inclined portion 712a that is inclined downward from the outdoor side toward the indoor side, and a lower rib vertical portion 712b that is lowered downward from the indoor side end of the lower rib inclined portion 712a. .
On the other hand, the opening / closing operation pin 72 formed on the outer peripheral surface of the rotation arm 3 is arranged between the upper rib 711 and the lower rib 712 of the operation member 71 when the shoji 2 is opened / closed. The shoji 2 is opened and closed and maintained at the open and closed positions by contacting the upper rib 711 and the lower rib 712.

(Opening / closing operation of shoji)
The opening / closing operation of the shoji by the opening / closing operation means will be described with reference to FIG.
As shown in FIG. 8A, when the shoji 2 is closed, the operation member 71 is operated to the upper position, and the opening / closing operation pin 72 provided on the rotary arm 3 is connected to the lower rib 712 of the operation member 71. By contacting the lower rib vertical portion 712b from the indoor side, the rotation arm 3 is prevented from rotating to the outdoor side, and the shoji 2 is locked in the closed state.
When the operating member 71 is operated downward by operating the operating means from the closed state shown in FIG. 8A, the opening / closing operation pin 72 is detached from the lower rib vertical portion 712b and goes through the state shown in FIG. 8B. Then, a freely movable state shown in FIG. 8C is opened and closed freely by an external force such as a pressure difference between the inside and outside of the room.

When the operator operates the operating means to operate the operating member 71 downward from the free movable state shown in FIG. 8C, the upper rib 711 of the operating member 71 is moved upward as shown in FIG. The rib inclined portion 711a abuts on the opening / closing operation pin 72, and the opening / closing operation pin 72 is forcibly moved to the outdoor side by the inclination, and further, the operation member 71 is operated downward, as shown in FIG. The rotary arm 3 is rotated until the opening / closing operation pin 72 reaches the outdoor side of the upper rib vertical portion 711b of the upper rib 711 of the operation member 71.
In the state shown in FIG. 8 (e), the opening / closing operation pin 72 contacts the outdoor side of the upper rib vertical portion 711b, and the sliding shaft 55 of the shoji 2 is supported by the shock absorbing means 6, so that the shoji 2 is Maintained in fully open position.

On the other hand, when the operator operates the operating means and operates the operating member 71 upward from the fully opened state shown in FIG. 8 (e), the opening / closing operation pin 72 is detached from the upper rib vertical portion 711b, and FIG. After the state (d), a free movable state shown in FIG. 8 (c) is opened and closed freely by an external force such as a pressure difference inside and outside the room.
When the operator operates the operating means and operates the operating member 71 upward from the free movable state shown in FIG. 8C, the lower part of the lower rib 712 of the operating member 71 is shown in FIG. 8B. The rib inclined portion 712a abuts on the opening / closing operation pin 72, and the opening / closing operation pin 72 is forcibly moved to the indoor side by the inclination, and further, the operation member 71 is operated downward, as shown in FIG. Then, the rotary arm 3 is rotated until the opening / closing operation pin 72 reaches the indoor side of the lower rib vertical portion 712b of the lower rib 712 of the operation member 71.
In the state shown in FIG. 8A, the shoji 2 is maintained in the closed state by the opening / closing operation pin 72 coming into contact with the indoor side of the lower rib vertical portion 712b.

  As described above, in the embodiment of the present invention, the operator can open and close the shoji 2 without touching the shoji 2 directly. Further, when the shoji 2 is closed and fully opened, the opening / closing operation pin 72 provided on the rotary arm 3 of the shoji 2 is in contact with the operation member 71 from the indoor / outside direction to maintain the state. Even if an external force such as wind is generated in the shoji 2, the external force is not transmitted in the vertical direction as the operation direction of the operation member 71, so that the closed and fully opened state of the shoji 2 can be stably maintained.

In the opening / closing operation means of the embodiment of the present invention, the inclination angles of the upper rib 711 and the lower rib 712 of the operation member 71 can be made different.
More specifically, when the urging force to the closed state is applied to the shoji 2, the inclination angle of the upper rib inclined portion 711 a of the upper rib 711 is changed as shown in FIG. 9. By making it larger than the inclination angle of the lower rib inclined part 712a (increasing the inclination), the operating force when operating from the free movable state of FIG. 9C to the fully open state of FIG. 9E. Can be made smaller (lighter) than the operating force when operating at the time of closing in FIG.
On the contrary, when the urging force to the open state is applied to the shoji 2, the inclination angle of the lower rib inclination part 712 a of the lower rib 712 is changed to the inclination angle of the upper rib inclination part 711 a of the upper rib 711. Also, the operating force when operating from the free movable state to the closed state can be made smaller (lighter) than the operating force when operating to the fully open state.
As described above, since the operation member 71 is composed of two upper and lower ribs, the operation force for opening and closing can be individually adjusted according to the natural ventilation window.
Further, as seen in the lower rib of FIG. 10, for example, by changing the inclination angle of the inclined portion of the rib in the middle, the inclination of the inclined portion with which the opening / closing operation pin abuts immediately before closing which requires relatively operating force. The operating force can be changed even in the closing operation, for example, by increasing the angle.

Further, in the opening / closing operation means of the embodiment of the present invention, two opening / closing operation pins 72 provided on the rotary arm 3 can be provided.
Specifically, as shown in FIG. 10, the rotary arm 3 is provided with a first opening / closing operation pin 72a and a second opening / closing operation pin 72b above the first opening / closing operation pin 72a. Accordingly, a second upper rib inclined portion 711c and a second upper rib vertical portion 711d with which the second opening / closing operation pin 72b abuts are formed on the indoor side (upper surface) of the upper rib 711 of the operation member 71.
Further, as shown in FIG. 11, the inclined portion 712a of the lower rib 712 is formed in a curved shape, and as shown in FIG. 12, both the inclined portions 711a and 712a of the upper rib 711 and the lower rib 712 are formed in a curved shape. You can also
By making the inclined portion curved, the first opening / closing operation pin 72a and the second opening / closing operation pin 72b can be smoothly moved along the curved shape.
As described above, by providing the two opening / closing operation pins, the rotation state of the rotating arm 3 in the closed state can be maintained by using the second opening / closing operation pin 72b located at a position relatively distant from the rotation center of the rotating arm 3. Since it can be performed, the closed state can be reliably maintained.

By using the operation member 71 shown in FIG. 13, a reliable closing operation can be performed with a light operation even during the closing operation. This will be specifically described below.
When the operator operates the operating means and operates the operating member 71 upward from the free movable state shown in FIG. 13A, first, the first opening / closing operation pin 72a contacts the lower rib inclined portion 712a of the lower rib 712. In contact therewith, the rotating arm 3 is rotated in the closing direction as shown in FIG. When the operation member 71 is further operated upward, the second opening / closing operation pin 72b is moved to the indoor side of the upper rib 711 of the operation member 71 as shown in FIG. 13C, and the second opening and closing operation pin 72b is moved as shown in FIG. The open / close operation pin 72b contacts the second upper rib inclined portion 711c of the upper rib 711.
In the subsequent upward movement of the operation member 71, the force applied to the first opening / closing operation pin 72 a by the lower rib inclined portion 712 a of the lower rib 712 and the second upper rib of the upper rib 711 are applied to the rotary arm 3. The shoji 2 can be closed by the force applied to the second opening / closing operation pin 72b by the inclined portion 711c.

  Therefore, by providing two opening / closing operation pins 72 for the rotary arm 3, as shown in FIG. 10, the operation member 71 acts on the first opening / closing operation pin 72a in the same manner as in FIGS. As shown in FIG. 13, the shoji 2 is also closed by the closing force with respect to the second opening / closing operation pin 72b that is separated from the first support shaft 31 during the closing operation, as shown in FIG. Therefore, the force required for the closing operation is reduced, and the closed state can be reliably maintained by the two pins.

This will be described below. The operation member 75 shown in FIG. 14 includes an upper rib 751 provided at an upper position of the operation member 75, a lower rib 752 provided at a lower position of the operation member 75, and a connecting portion that connects the upper rib 751 and the lower rib 752. 753.
The upper rib 751 of the operation member 75 includes an upper rib inclined portion 751a inclined upward from the indoor side toward the outdoor side, an upper rib vertical portion 751b extending vertically upward from the outdoor end of the upper rib inclined portion 751a, and an upper rib. The lower rib 752 has an upper rib upper portion 751c that extends obliquely upward from the vertical portion 751b and extends outward from the upper end of the lower rib vertical portion 752b and the lower rib vertical portion 752b that extend vertically to the indoor side. And a lower rib inclined portion 752a inclined upward.
A first opening / closing operation pin 72a is formed in the indoor side portion of the outer peripheral surface of the rotary arm 3 at a predetermined distance from the first support shaft 31, and the second opening / closing operation pin is located above the first opening / closing operation pin 72a and on the outdoor portion. 72b is formed, and the first opening / closing operation pin 72a is disposed between the upper rib 751 and the lower rib 752 of the operation member 75 and comes into contact with the upper rib 751 and the lower rib 752, thereby opening / closing the shoji 2 and While maintaining in the open position and the closed position, the second opening / closing operation pin 72b is in contact with the indoor surface of the upper rib vertical portion 751b of the upper rib 751, thereby maintaining the shoji 2 in the closed position.

As shown in FIG. 14A, when the shoji 2 is closed, the first opening / closing operation pin 72a is connected to the lower rib vertical portion 752b of the lower rib 752 of the operation member 75 operated to the upper position from the indoor side. When the second opening / closing operation pin 72b comes into contact with the upper rib vertical portion 751b of the upper rib 751 from the indoor side, the rotation of the rotary arm 3 to the outdoor side is prevented, and the shoji 2 is locked in the closed state. ing.
When the operating member 75 is operated downward by operating the operating means from the closed state shown in FIG. 14A, the first opening / closing operation pin 72a is detached from the lower rib vertical portion 752b of the lower rib, and the second When the opening / closing operation pin 72b is detached from the upper rib vertical portion 751b, the shoji 2 can move between the indoor and outdoor until the first opening / closing operation pin 72a shown in FIG. 14 (b) contacts the lower rib inclined portion 752a. It can be opened and closed freely by external force such as pressure difference.
Further, by operating the operating member 75 downward, the free movable region expands in the opening direction as shown in FIG. 14C, and the upper rib inclination of the upper rib 751 as shown in FIG. 14D. When the portion 751a abuts on the first opening / closing operation pin 72a, the first opening / closing operation pin 72a is forcibly moved to the outdoor side, and further, the operation member 75 is operated downward, so that FIG. As shown, the rotary arm 3 is rotated until the first opening / closing operation pin 72a reaches the outdoor side of the upper rib vertical portion 751b of the upper rib 751 of the operation member 75.
In the state shown in FIG. 14 (e), the first opening / closing operation pin 72a abuts on the outdoor side of the upper rib vertical portion 751b, and the slide shaft 55 of the shoji 2 is supported by the shock absorbing means 6, whereby the shoji 2 will be maintained in the fully open position.

On the other hand, when the operator operates the operating means and operates the operating member 75 upward from the fully opened state shown in FIG. 14 (e), the first opening / closing operation pin 72a is detached from the upper rib vertical portion 751b. After the state shown in FIG. 14D, the shoji 2 is freely movable in a predetermined range shown in FIG.
When the operator operates the operating means from the free movable state shown in FIG. 14 (c) to operate the operating member 75 upward, as shown in FIG. 14 (b), below the lower rib 752 of the operating member 75. The rib inclined portion 752a abuts on the first opening / closing operation pin 72a and the first opening / closing operation pin 72a is forcibly moved to the indoor side by the inclination, and further, the operation member 75 is operated downward, so that FIG. The closed state shown in a) is maintained.

That is, the first opening / closing operation pin 72a positioned below when the shoji 2 is fully opened is held in contact with the outdoor side of the upper rib vertical portion 751b of the operation member 75, and the operation member 75 is held in the vertical frame 13. , 14 within the expected width, the first opening / closing operation pin 72a also needs to be within the expected width of the vertical frames 13, 14. Therefore, in the embodiment shown in FIG. 14, as shown in FIG. 14 (e), the first opening / closing operation pin 72 a located below the rotary arm 3 is vertically connected to the rotary arm 3 when the shoji 2 is fully opened. It is a part that fits in the expected width of the frames 13 and 14 and is arranged in the indoor side part farthest from the first support shaft 31.
In this way, by arranging the first opening / closing operation pin 72a positioned below in the indoor portion, the first opening / closing operation pin 72a is further away from the first support shaft 31 in the same open state (angle). The operation force at the time of closing can be reduced.

  Further, the second opening / closing operation pin 72b positioned above the rotary arm 3 is also configured to contact the upper rib vertical portion 751b provided outside the rotary arm 3 and provided above the upper rib 751. Thereby, it can move away from the 1st support shaft 31, and the maintenance force of closure can be enlarged.
