As shown in FIG. 1, the coil spring 28 is connected to the slider 26 at the end on the door tip side and connected to a moving piece 48 screwed with a screw 53 at the end on the door bottom side. is erected in the frame 8, by operating the screw 53 with a tool from the door bottom side, the moving piece 48 moves in the left-right direction, the coil spring 28 expands and contracts, and the urging force can be adjusted.

As shown in FIGS. 1 and 4, an open trigger 5 and a close trigger 7 are provided on the lower surface of the upper frame 1 . The open trigger 5 has a vertical surface 49 on the door tip side, and an inclined surface 50 on the door trailing side, which slopes upward toward the door trailing edge side. The closing trigger 7 has a convex portion 51 that is narrower in the horizontal direction than the concave portion 45 of the closing hook 6 .
As shown in FIG. 4, the open hook 4 is provided near the interior side of the case 19, the close hook 6 is provided near the exterior side of the case 19, and the open trigger 5 and the close trigger 7 are arranged correspondingly. The positions are shifted in the prospective direction. Therefore, the opening hook 4 does not come into contact with the closing trigger 7 when the shoji 2a and 2b are opened and closed.

The outer shoji 2a and the inner shoji 2b are erected between the rails 16, 52 of the upper and lower frames 1, 9 in the same manner as the ordinary sash. At this time, as shown in FIGS. 7(b) and 8(b), when the upper end of the open hook 4 comes into contact with the lower surface of the upper frame 1, it rotates clockwise about the shaft 23 and automatically retracts. When the upper end of the protrusion 46b on the side of the door bottom comes into contact with the lower surface of the upper frame 1, the closing hook 4 rotates clockwise about the shaft 27a on the side of the door and automatically retracts. After that, when the sliding doors 2a and 2b are lowered, the opening hook 4 and the closing hook 6 return to their original postures shown in FIG.

Next, the movement of the sliding door closing assist mechanism 3 when opening and closing the shoji 2a will be described. FIG. 5(a) shows a state in which the shoji 2a is completely closed. At this time, the coil spring 28 is in the most contracted state, the moving rack 20 and the slider 26 are in the most moved position toward the door bottom side, and the open hook 4 is positioned slightly away from the opening trigger 5 toward the door tip side, and the closing hook 6 has the protrusion 46b on the door trailing edge side positioned at the door trailing edge side of the closing trigger 7 .
When the shoji 2a begins to open, as shown in FIG. The slider 26 integrated with the pinion gear 25 and the closing hook 6 also move toward the door, during which the coil spring 28 is pulled. The urging force in the direction in which the shoji 2a closes is accumulated.
After that, as shown in FIG. 5(c), when the pinion gear 25 moves to the vicinity of the end of the fixed rack 24 on the door leading edge side, the shaft 27a of the closing hook 4 on the door leading edge side is pushed into the closing hook guide groove 31 of the case 19. The coil spring 28 is held in the most stretched state by dropping into the downward protrusion 38a on the side of the door, and the accumulation of the urging force is completed.
After that, as shown in FIG. 5D, the shaft 23 of the open hook 4 falls into the downward protrusion 36 of the open hook guide groove 31 of the case 19, so that the open hook mounting member 22 is moved downward with the pin 21 as a fulcrum. It rotates and the open hook 4 climbs over the open trigger 5.
After that, as shown in FIG. 5(e), the shoji 2a opens while the biasing force remains accumulated. At this time, the opening hook 4 does not interfere with the closing trigger 7 because the opening hook 4 is displaced from the closing hook 6 in the prospective direction as described above.

FIG. 6 shows the movement of the sliding door closing assist mechanism 3 when closing the shoji 2a. As shown in FIG. 6A, when the shoji 2a is closed, the open hook 4 interferes with the open trigger 5, but the upper end of the open hook 4 is pushed by the inclined surface 50 of the lower surface of the open trigger 5, thereby opening the hook. 4 rotates clockwise and climbs over the open trigger 5 .
When the shoji 2a is further closed, as shown in FIG. 6(b), the protrusion 46b of the closing hook 6 on the trailing edge side hits the closing trigger 7, causing the closing trigger 7 to move around the door trailing shaft 27b as a fulcrum. direction, and the shaft 27a on the side of the door is released from the downward protrusion 38a of the closing hook guide groove 34 of the case 19. As shown in FIG.
Thereafter, as shown in FIG. 6(c), with the closing hook 6 hooked on the closing trigger 7, the urging force accumulated in the coil spring 28 closes the shoji 2a. At this time, the damper 29 works to slowly close the shoji 2a.
When the shoji 2a is completely closed, as shown in FIG. 6(d), the shaft 27b of the closing hook 6 falls into the downward protrusion 38b of the closing hook guide groove 34 of the case 19 on the side of the door trailing edge. away from the closing trigger 7;

In the sliding door closing assist mechanism 3, when the biasing force is accumulated in the coil spring 28 (see FIG. 5B), the amount of movement in the opening direction of the shoji 2a is equal to that when the biasing force accumulated in the coil spring 28 is released (see FIG. 6(c)) is longer than the amount of movement of the shoji 2a in the closing direction. The ratio of this amount of movement is determined by the gear ratio of the large gear 42 and the small gear 43 of the pinion gear 25. Specifically, the amount of movement of the shoji 2a in the opening direction when accumulating the biasing force in the coil spring 28 is 174 mm. The amount of movement of the shoji 2a in the closing direction when the biasing force accumulated in 28 is released is 67 mm. In this way, by increasing the amount of movement of the shoji 2a in the opening direction when accumulating the biasing force and shortening the amount of movement of the shoji 2a in the closing direction when the biasing force is released, it is possible to open the shoji 2a. The resistance can be reduced and the closing force of the shoji 2a can be increased to securely close even the heavy shoji of the terrace window.

FIG. 9 shows another embodiment of fittings of the present invention, in which one trigger 54 is used both as the open trigger 5 and the close trigger 7 . The sliding door closing assist mechanism 3 uses the same one as described above.
In this case, since the distance between the opening hook 4 and the trigger 54 when fully closed becomes longer, when the shoji 2a is opened, the time between the start of opening and the start of accumulation of the urging force becomes longer. Other than that, it works the same as described so far.

As described above, in this fitting, the sliding door (outer shoji 2a, inner shoji 2b) is provided with the sliding door closing assist function 3, and the sliding door closing assist mechanism 3 engages the open hook 4 with the open trigger 5 of the frame 1. By opening the sliding doors 2a and 2b in the stopped state, biasing force is accumulated in the direction of closing the sliding doors 2a and 2b, and when the sliding doors 2a and 2b are closed to a predetermined position, the closing hook 6 engages the closing trigger 7 of the frame 1. By locking and releasing the biasing force, it is possible to assist the smooth closing operation of the sliding doors 2a and 2b. Furthermore, the opening hook 4 and the closing hook 6 are always urged in a protruding direction, so that when the sliding doors 2a and 2b are erected between the horizontal frames (upper frame 1 and lower frame 9), the horizontal frame 1 , the sliding doors 2a and 2b can be erected between the horizontal frames 1 and 9 in the same manner as a normal sliding door.
Since the sliding door closing assist mechanism 3 is arranged between the anti-vibration guards 55, 55 on the indoor side of the rail 16 of the upper frame 1 and on the door trailing side, it is difficult for rainwater to enter the sliding door closing assist mechanism 3. - 特許庁In addition, it can be attached to the shoji inside and outside, and it does not interfere with the installation of the screen door.
In this fitting, the amount of movement of the sliding doors 2a and 2b in the opening direction when accumulating the urging force is longer than the amount of movement of the sliding doors 2a and 2b in the closing direction when the urging force is released. The resistance to open the 2b can be reduced, and the closing force of the sliding doors 2a and 2b can be increased to reliably close even the heavy sliding doors of the terrace windows.
In addition, in this fitting, the opening hook 4 is separated from the opening trigger 5 when the sliding doors 2a and 2b are closed, and the biasing force starts to accumulate after the sliding doors 2a and 2b are slightly opened. The sliding door does not become heavy when it starts to open, and can be opened smoothly.
With this fitting, the urging force can be easily adjusted by operating the screw 53 from the door bottom side while the sliding doors 2a and 2b are erected in the frame 8. - 特許庁
When the sliding door closing assist mechanism 3 is attached to the indoor side surface of the sliding door, the sliding door closing assist mechanism 3 can be installed only on the inner shoji 2b, but by storing it in the upper frame 11, it can be installed on both the outer shoji 2a and the inner shoji 2b. A sliding door closing assist mechanism 3 can be installed.
In addition, since the sliding door closing assist mechanism 3 is housed in the upper frame 11, this fitting has the same appearance and interior design as a normal sash, and has good design. In addition, the sliding door closing assist mechanism 3 is easy to install and remove, and functions as a sash even when it is removed. Furthermore, the existing sash can be installed by using the glass as it is and replacing only the upper frame 11.例文帳に追加

The invention is not limited to the embodiments described above. The specific structure of the sliding door closing assist mechanism can be changed as appropriate. The shape and movement of the open hook and the closed hook can be changed as appropriate, and for example, they may simply slide up and down. This fitting can be applied not only to a double sliding window but also to a single sliding window.
