Embodiment of the invention The structure of the proposed opening/closing device will be explained below with reference to drawings of embodiments. J is a window frame (Fig. 15) that is attached to the opening of a building, and the window frame J is installed on the indoor side of the inner peripheral surface. It has an inward wall K that projects in the circumferential direction. M is a shoji that is attached to the inner periphery of the window frame J to open and close, and the shoji M has glass attached to the inner periphery of the stile frame m, and has a groove N that opens toward the outer periphery on the outer periphery of the stile frame m. There is.
1 is a proposed opening/closing device (Fig. 3) installed between a window frame J and a shoji frame m. It consists of a shoji stile arm 4 connected to the slider 3 via a short arm 5, a long arm 7 connected to the stile arm 4 and the frame rail 2, and a middle arm 6 connected to the long arm 7 and the slider 3. . The frame rail 2 attached to the window frame J consists of a vertically long fixed wall 20 (Fig. 6) that is screwed to the vertical frame inner circumferential surface j of the window frame J, and a hook wall 21 that is folded back from the indoor side toward the inner circumference. A blind groove 12 that opens toward the outside of the room is formed on the indoor side of the frame rail 2, and one end of the long arm 7 is rotatably pivoted at one end of the frame rail fixing wall 20, specifically, at the lower end. (FIG. 3A), and through holes 22 (FIG. 6) are appropriately bored in the hook wall 21 above the middle part of the frame rail 2. The slider 3 that slides along the frame rail 2 has a partition wall 31 projecting inward from the middle part of the base body 30 (Fig. 12), and arms attached to the base body 30 above and below the partition wall 31. Pivot holes 3e and 3d are drilled,
A head 32 is provided on the indoor side of the base 30 and is inserted into the bag groove 12 of the frame rail 2 and cannot be removed.
Then, the steel ball 13 that is locked in the through hole 22 of the hook wall 21 of the frame rail 2 is biased in the protruding direction by the spring 23, and the short arm 5 is inserted into the upper pivot hole 3e, and the middle arm 6 is inserted into the lower pivot hole 3d. The E and D partition walls 31 allow the short arm 5 to swing only upwards from the horizontal state, and the middle arm 6 to swing only downwards from the horizontal state. The shoji stile arm 4, which is connected to the slider 3 via the short arm 5, is slightly shorter than the entire length of the frame rail 2, and is screwed from the upper part of the outer periphery of the groove N of the shoji stile frame m, specifically, the vertical stile groove N. It is fixed with a stopper (first
5), the tip of the short arm 5, one end of which is pivotally connected to the slider 3, and the upper end of the stile arm 4 are pivotably connected F.
The tip of the long arm 7, which has one end A pivoted to the lower part of the frame rail 2, is pivoted to approximately the middle of the frame arm 4.
When the short arm 5 and the stile arm 4 connected to the slider 3 via the arm 5 are in a straight line (Fig. 4), the middle part of the stile arm 4 is connected to the long arm from the bottom of the frame rail 2. Supported by 7. The tip of the middle arm 6, whose one end is pivoted D to the lower pivot hole 3d of the slider 3, is the pivot point of the long arm 7, which is connected to the frame rail 2 and the stile arm 4. It is pivoted toward C, and the distance h between the short supports from the pivot point C to the pivot point B of the long arm 7 and the middle arm 6 (Fig. 2) is
The length is the same as that from the pivot point F of the stile arm 4 and the short arm 5, through the pivot point E of the short arm 5 and slider 3, to the pivot point D of the slider 3 and middle arm 6, and The distance between the long supports 1 from the pivot point C of the stile arm 4 and the long arm 7 to the pivot point F of the stile arm 4 and the short arm 5 and the distance between the pivot points B and D at both ends of the middle arm 6 are approximately the same. A four-joint mechanism in which L between the long supports of the stile arm 4 and the middle arm 6, and h between the short supports of the long arm 7 and the short arm 5 between one of the short supports FD can be bent freely. Configure. Reference numeral 9 is a washer, which is interposed at the overlapping parts C and F of the frame arm 4 and the long and short arms 7 and 5, the overlapping parts E, D, and A of the frame rail 2 and the long arm 7, and the overlapping part B of the long and medium arms 7 and 6. be done. Further, reference numeral 19 denotes a bush that is inserted into the pivot joint of each arm 4, 5, 6, 7, and each arm 4, 5, 6, 7 can be rotated by a pin 29 inserted into the bush 19. Ru. Reference numeral 8 denotes a shoji pulling block (Fig. 1) that is attached to the upper end of the frame rail 2. A short arm 5 has a vertically elongated through hole 18 and rotates toward the block 8 when the shoji M is closed by the inclined surface 81.
The pulling pin 15 protruding from the front is pulled toward the indoor side. The pulling block 8 is fixed with a screw screwed into the frame rail 2 through a through hole 18 in the mounting wall 80, and can be adjusted up and down within the range of the through hole 18.

Since the opening/closing device of the present invention has the above structure, it is installed between the window frame J and the shoji frame m, and specifically, the frame rail 2 is screwed to the vertical frame inner peripheral surface j, and the stile arm 4 is attached to the shoji frame. Fix it to the outer periphery of the stile concave groove N with screws. At that time, install the frame rail 2 with the long arm pivot point A facing down, and attach the short arm pivot point F of the stile arm 4.
The shoji frame m is attached so that its side is positioned at the upper end of the shoji frame m.

A short arm 5 and a middle arm 6 are pivotally connected to the slider 3 of the proposed opening/closing device, a stile arm 4 is pivotally connected to the short arm 5,
Long arm 7 pivoted to stile arm 4 and middle arm 6
However, it becomes like a four-jointed mechanism that expands and contracts with the pivot points D and E of the slider 3 as the base, and when the shoji M is opened, it is extended the most, and the pivot point C of the stile arm 4 and the long arm 7 is as shown in Fig. 4. It is away from the base point, which is the position shown, and when the shoji M is closed, it is bent the most and the pivot point C is pulled to the same position as the base point.

When the shoji M is in the open state, the shoji M is attached to the window frame J.
In other words, the stile arm 4, which is attached to the shoji stile frame m, forms a straight line horizontally via the short arm 5 from the slider 3, which has descended to the middle part of the frame rail 2. The middle part of the horizontal frame arm 4 is supported by a long arm 7 whose one end is pivoted to the lower part of the frame rail 2.

To close the open shoji M, push up the top of the horizontal shoji M, or pull the bottom of the shoji M downward toward the interior of the room, and the slider 3 will close. As M is closed, the long arm 7 slides upward, and the long arm 7 collapses and rotates toward the interior of the room around the pivot point A with the frame rail 2, and the middle arm 6 pivots with the pivot point A with the rising slider 3. Centering on D, long arm 7
It oscillates according to the lodging. The short arm 5 swings about the pivot point E with the rising slider 3 in response to the closing of the stile arm 4. The slider 3 that slides in the upward direction along the frame rail 2 reaches the top dead center just before the shoji M completes closing, but at this time the short arm 5 pivoted to the slider 3 Since it is possible to fold down and rotate toward the frame rail 2 side around the landing point E, the stile arm 4 pivotally attached to the tip of the short arm 5, that is, the upper part of the shoji M can be drawn toward the indoor side. .

This attraction is performed as follows.

When the slider 3 approaches the top dead center, the pulling pin 15 of the short arm 5 comes into contact with the inclined surface 81 of the pulling block 8 attached to the frame rail 2.

When the shoji M, that is, the stile arm 4, is further retracted indoors, the long arm 7 is rotated indoors around the pivot point A, and the pivot point C rises, albeit slightly. Figure 3).

As a result, the pivot point F performs a curved movement that is a combination of upward movement and movement towards the indoor side.

The pulling pin 15 also moves in the same way as the pivot point F, but since the pulling pin 15 is in contact with the inclined surface 81 of the pulling block 8, the pulling pin 15
is guided toward the indoor side along the inclined surface 81.

This movement means that the short arm 5 is actively rotated toward the indoor side, and the pivot point F of the stile arm 4, that is, the shoji M is drawn toward the indoor side.

As a result of the above, the shoji M is strongly drawn toward the indoor side when closed, and airtightness is further ensured.

When the shoji M is completely closed (FIG. 4), the slider 3 moves to the top of the frame rail 2, and the short arm 5 pivoted to the slider 3 moves toward the top, and
The middle arm 6 collapses and rotates toward the bottom, and the long arm 7 pivoted to the bottom of the frame rail 2 collapses toward the top and is placed between the fixed wall 20 of the frame rail 2 and the stile arm 4. The short arm 5, middle arm 6, and long arm 7 are folded so as to overlap.

In addition, when closing the shoji M, if there is no structure in which the short arm 5 is actively guided toward the indoor side by the pulling block 8 and the pulling pin 15, the shoji will further close from the state shown in FIG. Even if an attempt is made to close M (usually by pulling the lower part of the stile arm 4 towards the indoor side), the stile arm 4 rotates around the pivot point C and the short arm 5 moves towards the outdoor side around the pivot point E. The stile arm 4 becomes parallel to the frame rail 2 before the shoji M is completely closed, making it difficult to close it securely.

As described above, the stile arm 4 attached to the shoji M is connected to the slider 3 via the short arm 5, so the shoji M starts collaborating with the pulling block 8 a little before the closing is completed. It is attracted to the window frame J, and is quickly separated from the window frame J at the beginning of opening.

In addition, the slider 3 that slides up and down as the shoji M opens and closes is provided with a steel ball 13 that is biased in the protruding direction by a spring 23, so that the slider 3 touches the frame rail hook wall 21.
Each time the opening position of the through hole 22 is reached, it is locked and the shoji M can be opened in stages.

Note that the shoji opening/closing device of the present invention is not limited to the above-mentioned embodiment. For example, the opening/closing device may be installed upside down, with the pulling block mounting side of the frame rail 2 facing down, and the short arm pivot of the stile arm 4. If you install the shoji so that the receiving side is located at the lower end of the shoji frame m,
The lower part of the shoji M can be moved up and down along the window frame J, and the upper part of the shoji M can be opened and closed by jutting out from the window frame J to the outside. Also, stile arm 4 attached to shoji stile frame m
If it is slightly longer than 1/2 of the height of the shoji or slightly longer than l between the long supports, the purpose will be achieved. , the shape and structure of each arm 4, 5, 6, 7, and the pivoting means of each arm 4, 5, 6, 7 can be changed as appropriate unless it goes against the gist of the present invention.

Effect of the invention Therefore, if the proposed opening/closing device is installed between the shoji M of the window frame J and the shoji M is opened and closed in a sliding manner,
A frame rail 2 of the opening/closing device is attached to a window frame J, and a stile arm 4 attached to a shoji M is connected via a short arm 5 to a slider 3 that slides up and down along this frame rail 2. 4 is supported by the long arm 7 from the lower part of the frame rail 2, and the middle arm is connected to the long arm 7 from the slider 3, forming a unique four-section mechanism. The opening and closing of the shoji M attached to the shoji is really smooth. especially,
Since the short fulcrum h on the frame rail 2 side is bendable, the shoji M quickly separates from the window frame J at the beginning of opening and is drawn to the window frame J a little before the completion of closing. As a result, the opening/closing operation of the shoji M can be made easier while ensuring airtightness when the shoji is closed.

Furthermore, the frame rail 2 has a blind groove 12 that opens toward the outside, and a thin fixed wall 20 that opens the outside of the groove.
With the configuration requirements that the slider 3 is inserted into the blind groove 12 of the frame rail 2 and cannot be removed, the head 32 and its outdoor side are the thin base body 30,
Embodiment As shown in FIG. 6, the short arm 5, middle arm 6, long arm 7, and slider 3 can be accommodated within the thickness dimension of the frame rail 2, and the shoji opening/closing of the present invention is formed thin as a whole. The device is based on Example 1.
As shown in FIG. 5, it can be easily accommodated in the narrow space between the inner circumferential surface of the vertical frame of the window frame J and the outer circumferential surface of the shoji frame m, and the opening area of the window is not reduced much.

Furthermore, in addition to the four-bar mechanism with the above structure,
A pulling pin 15 is provided on the short arm 5, and the frame rail 2
A structure in which a pulling block with a sloped surface whose lower surface digs in toward the upper part of the indoor side is attached to the upper end, and a pulling pin 15 is attached to the inclined surface 81 of the pulling block 8 just before the shoji M is closed. When the long arm 7 is rotated indoors by the operation of further closing the shoji M, the stile arm 4 moves upward and engages with the inclined surface 81 of the pulling block 8. , the short arm 5 is actively and strongly rotated toward the indoor side, whereby the shoji M is drawn toward the indoor side and reliably closed. As a result, the airtightness of the window becomes even higher.
