Will be described.
As shown in FIGS. 1 and 4, the sliding door closing assist device 3 includes a case 19 that is housed and fixed in the housing groove 18 of the upper lid 11, and a movable rack 20 that is provided on the upper portion of the case 19 so as to be movable in the left-right direction. An open hook mounting member 22 that is connected to the end of the movable rack 20 with a pin 21 in the prospective direction, and an open hook 4 that is pivotally attached to the open hook attachment member 22 with a shaft 23 in the prospective direction; A fixed rack 24 provided at the lower part of the case 19 so as to face the movable rack 20, a pinion gear 25 meshing with the movable rack 20 and the fixed rack 24, a slider 26 having a pinion gear 25 pivotally attached to an end on the door end side, A closed hook 6 provided by engaging shafts 27 a and 27 b at the door butt side end of the slider 26, and a coil spring 28 and a damper 29 connected to the door butt side end of the slider 26 are provided.

  As shown in FIGS. 1 and 4, the case 19 is formed in a U-shaped cross section with the upper side open, and includes an open hook guide groove 31 for guiding the shaft 23 of the open hook 4 to the wall 30 inside and outside, and a pinion gear 25. A pinion gear guide groove 33 for guiding the shaft 32 and a closed hook guide groove 34 for guiding the shafts 27a and 27b of the closed hook 6 are provided. The open hook guide groove 31 has a horizontal straight portion 35 and a downward projecting portion 36 provided at a door end side end portion of the straight portion 35. The closed hook guide groove 34 has a horizontal straight portion 37 and downward projecting portions 38a and 38b provided at the door end side end portion and the door bottom side end portion of the straight portion 37, respectively.

  As shown in FIG. 1 (b), the open hook 4 has a vertical surface 39 on the door bottom side, and the door tip side is formed in an arcuate surface 40 so that the upper side is thinned. The upper end protrudes from the upper edge of the upper collar 11. The open hook 4 is pivotally attached to the open hook mounting member 22 with a shaft 23 in the expected direction, and is provided so as to be able to rotate only in the clockwise direction with the shaft 23 as a fulcrum. A return spring 41 is provided around the shaft 23.

  As shown in FIG. 1B, the pinion gear 25 includes a large gear 42 and a small gear 43 that are concentrically integrated. The large gear 42 meshes with the movable rack 20, and the small gear 43 is connected to the fixed rack 24. I'm engaged. The gear ratio between the large gear 42 and the small gear 43 is 5: 3.

  As shown in FIG. 1 (c), two rows of engaging grooves 44a and 44b are provided from the upper edge of the end of the slider 26 on the door butt side, and the closing hook 6 is inserted into the engaging grooves 44a and 44b. The two shafts 27a and 27b are engaged with each other. The closed hook 6 is provided with a recess 45 at the upper edge portion, and protrusions 46a and 46b are formed on the door end side and the door bottom side. The closed hook 6 is held in an inclined posture so that the door bottom side is raised by being pulled by the spring 47 on the door tip side, and the protrusion 46 b on the door bottom side protrudes from the upper edge of the upper hook 11.

  As shown in FIG. 1, the coil spring 28 has an end on the door side connected to the slider 26, and an end on the door bottom side connected to a moving piece 48 screwed with a screw 53. When the screw 53 is operated from the door butt side with a tool in a state where the frame 8 is built in the frame 8, the moving piece 48 moves in the left-right direction and 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 end side, and has an inclined surface 50 inclined on the door bottom side so as to become higher toward the door bottom side. The closing trigger 7 has a convex portion 51 that is narrower in the left-right direction than the concave portion 45 of the closing hook 6.
As shown in FIG. 4, the open hook 4 is provided closer to the indoor side of the case 19, the closed hook 6 is provided closer to the outdoor side of the case 19, and the open trigger 5 and the closed trigger 7 correspond to this. The position is shifted in the expected direction. Therefore, the opening hook 4 does not hit the closing trigger 7 when the shoji 2a and 2b are opened and closed.

  The external shoji 2a and the internal shoji 2b are built up and down between the rails 16 and 52 of the upper and lower frames 1 and 9 in the same manner as a normal sash. At that 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 in the clockwise direction around the shaft 23 and automatically retracts. When the upper end of the projection 46b on the door butt side comes into contact with the lower surface of the upper frame 1, the closing hook 4 rotates in the clockwise direction about the door tip side shaft 27a and automatically retracts. Thereafter, when the shoji 2a and 2b are lowered, the open hook 4 and the close hook 6 return to the original posture shown in FIG.

Next, the movement of the sliding door closing assist mechanism 3 when the shoji 2a is opened and closed will be described. FIG. 5A shows a state in which the shoji 2a is fully closed. At this time, the coil spring 28 is in the most contracted state, and the movable rack 20 and the slider 26 are in the position most moved to the door bottom side. Is at a position slightly away from the open trigger 5 toward the door end, and the projection 46 b on the door bottom side of the closing hook 6 is positioned on the door bottom side of the closing trigger 7.
When the shoji 2a starts to open, as shown in FIG. 5 (b), the opening hook 4 is hooked on the opening trigger 5, whereby the movement of the opening hook 4 and the moving rack 20 is restricted, and the pinion gear 25 is fixed to the fixed rack 24. Therefore, it rotates counterclockwise and moves toward the door tip side, and the slider 26 and the closing hook 6 integrated with the pinion gear 25 also move toward the door tip side, during which the coil spring 28 is pulled. The urging force in the direction in which the shoji 2a is closed is accumulated.
After that, as shown in FIG. 5C, when the pinion gear 25 moves to the vicinity of the door end side end portion of the fixed rack 24, the door end side shaft 27 a of the closed hook 4 moves into the closed hook guide groove 31 of the case 19. The coil spring 28 is held in the most extended state by dropping into the downward protrusion 38a on the door end side, and the accumulation of the urging force is completed.
Thereafter, as shown in FIG. 5 (d), the shaft 23 of the open hook 4 falls into the downward projection 36 of the open hook guide groove 31 of the case 19, so that the open hook mounting member 22 faces downward with the pin 21 as a fulcrum. Rotate and the open hook 4 gets over the open trigger 5.
After that, as shown in FIG. 5E, the shoji 2a is opened with the urging force accumulated. At that time, as described above, since the opening hook 4 is shifted in the expected direction from the closing hook 6, the opening hook 4 does not interfere with the closing trigger 7.

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 hook 4 is pushed by the inclined surface 50 on the lower surface of the open trigger 5 to open the hook. 4 rotates clockwise and gets over the open trigger 5.
When the shoji 2a is further closed, as shown in FIG. 6 (b), the projection 46b on the door butt side of the closing hook 6 hits the closing trigger 7, so that the closing trigger 7 uses the door butt side shaft 27b as a fulcrum. Rotate in the direction, and the door-side shaft 27a is released from the downward projecting portion 38a of the closed hook guide groove 34 of the case 19.
Thereafter, as shown in FIG. 6C, the shoji 2 a is closed by the urging force accumulated in the coil spring 28 in a state where the closing hook 6 is hooked on the closing trigger 7. At this time, the shoji 2a is slowly closed by the action of the damper 29.
When the shoji 2a is completely closed, as shown in FIG. 6D, the shaft 27b of the closed hook 6 falls into the downward protrusion 38b on the door-side side of the closed hook guide groove 34 of the case 19, so that the closed hook 6 is Move away from the closing trigger 7.

  The sliding door closing assist mechanism 3 is configured such that the amount of movement in the opening direction of the shoji 2a when accumulating the urging force in the coil spring 28 (see FIG. 5B) is released when the urging force accumulated in the coil spring 28 is released (see FIG. 5). 6 (c)) is longer than the moving amount of the shoji 2a in the closing direction. The ratio of the 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 the biasing force is accumulated in the coil spring 28 is 174 mm, and the coil spring The amount of movement in the closing direction of the shoji 2a when the urging force accumulated in 28 is released is 67 mm. In this way, the amount of movement in the opening direction of the shoji 2a when accumulating the urging force is long, and the amount of movement in the closing direction of the shoji 2a when the urging force is released is shortened, thereby opening the shoji 2a. The resistance can be reduced, and the closing force of the shoji 2a can be increased to reliably close the shoji with a heavy terrace window.

FIG. 9 shows another embodiment of the joinery of the present invention, and shows a case where the open trigger 5 and the closed trigger 7 are combined with one trigger 54. The sliding door closing assist mechanism 3 is the same as that described so far.
In this case, since the distance between the opening hook 4 and the trigger 54 when fully closed is increased, when opening the shoji 2a, the time from the start of opening until the accumulation of the urging force is increased. Otherwise, it operates in the same way as described above.

As described above, in the present fitting, the sliding door closing assist function 3 is provided in the sliding doors (the external shoji 2a and the inner shoji 2b), and the sliding door closing assist mechanism 3 engages the opening hook 4 with the opening trigger 5 of the frame 1. When the sliding doors 2a and 2b are opened in the stopped state, an urging 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 and the closing trigger 7 of the frame 1 By engaging and releasing the urging force, the smooth closing operation of the sliding doors 2a and 2b can be assisted. Further, the open hook 4 and the closed hook 6 are always urged in a protruding direction, and when the sliding doors 2a and 2b are built between the horizontal frames (the upper frame 1 and the 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 disposed between the indoor side door end side and the door bottom side steady rests 55, 55 of the rail 16 of the upper frame 1, rainwater hardly enters the sliding door closing assist mechanism 3. In addition, it can be attached to internal and external shoji screens, and does not interfere with the screen door installation.
This joiner makes the sliding doors 2a, 2b moving in the opening direction when accumulating the urging force longer than the moving amount in the closing direction of the sliding doors 2a, 2b when the urging force is released. The resistance at the time of opening 2b can be reduced, and the sliding doors 2a and 2b can be increased in closing force, so that even a sliding door with a heavy terrace window can be reliably closed.
Further, in this joinery, the opening hook 4 is separated from the opening trigger 5 with the sliding doors 2a and 2b closed, and the accumulation of the urging force is started after the sliding doors 2a and 2b are slightly opened. The sliding door does not become heavy when it begins to open, and can be opened smoothly.
In the present fitting, the biasing force can be easily adjusted by operating the screw 53 from the door bottom side while the sliding doors 2a and 2b are still built in the frame 8.
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 shroud 2b. The sliding door closing assist mechanism 3 can be installed.
In addition, since the sliding door closing assist mechanism 3 is housed in the upper arm 11 of the present fitting, the appearance and the interior design are the same as those of a normal sash, and the design is good. In addition, the sliding door closing assist mechanism 3 can be easily installed and removed, and functions as a sash even when it is removed. Furthermore, it is possible to install the existing sash by using only the glass and replacing only the upper arm 11.

  The present 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 way of movement of the open hook and the closed hook can be changed as appropriate. For example, it may simply slide up and down. The joinery is not limited to the sliding window, but can also be applied to a single sliding window.
