Further, the lower end portions of the inner surfaces of the projecting edges 30a, 30a facing the depth space 30b are formed as inclined surfaces 30c with tapered lower ends (see FIG. 2).

On the other hand, as shown in FIG.
The third interlocking rod 32 is formed as a protruding shaft and is connected to a third interlocking rod 32 that moves up and down in conjunction with the rotational operation of the handle.

On the other hand, each of the upper stile, rear stile, and lower stile of the sliding door is provided with a pulling mechanism that pulls the sliding door toward the front.

At least one location in the length direction of the upper stile of the sliding door is provided with a pulling mechanism as shown in FIGS. 6 and 7, for example. This pulling mechanism is driven by an upper interlocking rod 33 that moves in conjunction with the handle devices B, B1, and this upper interlocking rod 33 is, for example, a corner deflector as shown in FIG. It is connected to the handle device via 34.

That is, in FIG. 8, the reference numeral 35 indicates a corner block, and this corner block 35, which has an L-shaped overall shape, is located at the joint between the door stop frames 1 and 2 of the sliding door and the upper frame 36 (see FIG. 7). A guide slit 37 curved in an arc shape is formed inside the guide slit 37 . A flexible belt 38 is fitted into the guide slit 37 so as to be slidable in its length direction.

Connecting holes (not numbered) are opened at both ends of the flexible belt 38, and one connecting hole (on the left in FIG. 8) has a third connector 39 protruding from one end. The connecting pin 41 is fitted, and the third connector 3
The other end of 9 is similarly connected to the second interlocking rod 25.

On the other hand, the upper end of a connecting pin 41 that is implanted in the fourth connector 42 and passes through the upper interlocking rod 33 is fitted into the other connecting hole of the flexible belt 38 . With the above configuration, the upper interlocking rod 33 is connected to the second interlocking rod 25 via the flexible belt 38, the third and fourth connectors 39, 42, etc., and the second interlocking rod 33 is connected to the second interlocking rod 25 by operating the handle devices B, B1. In conjunction with the vertical movement of 25, it moves in the left-right direction in FIGS. 6 and 8.

Returning to the explanation of the pulling mechanism shown in FIGS. 6 and 7, the pulling mechanism in the upper stile 36 has a cam body 43 attached to the upper interlocking rod 33, and this cam body 43 has a vertical A horizontally projected trapezoidal drawing cam surface 43a having a generatrix is formed. A support roller 44 having a vertical rotation shaft is rotatably supported at the upper end of the cam body 43.
The support roller 44 is arranged so as to contact or be very close to a back-up plate 46 which is vertically provided on the side surface of the upper stile 36 on the packing strip 45 (FIG. 7) side.

On the other hand, on the lower surface side of the upper frame of the sash 47, a pulling roller 48 that engages with the cam body 43 is vertically provided. The fixed position of the pulling roller 48 in the moving direction of the sliding door is as shown in FIGS. 6 and 7 when the sliding door is in the door closing position. 6), the upper interlocking rod 33 is set to move forward by the amount of movement α, and the position of the pulling roller 48 in the expected direction of the sliding door is set to be in line with the pulling cam surface 43a, as shown in FIG. movement trajectory and attraction amount β
It is determined that there will be interference.

As a result, when the handle lever HL is rotated 180 degrees after advancing the sliding door to the door closing position (see Fig. 3), the upper interlocking rod 33 is moved by α as shown in Fig. 6 in conjunction with this handle operation. The cam body 43, which is integrated with the interlocking rod 33, interferes with the pulling roller 48 and is pushed upward in FIG. 6 and to the right in FIG. was suppressed by Satsushipatzkin Article 45 (Figure 7). At this time, since the cam body 43 is supported by the backup plate 46 via the support roller 44, the cam body 43
This effectively prevents the top from falling over.

In order to enable the sliding door to be pulled in as described above, a foldable door roller as shown in FIG. 9 is attached to the lower stile of the sliding door.

Further, the pulling mechanism in the joining frame is constructed as shown in FIGS. 10 to 12. In these figures, the reference numeral 49 indicates a matching stile of the sliding door, and a guide case 51 with a rectangular cross section is fixedly installed, for example, at approximately the center of the matching stile 49. A U-shaped operating frame 52 is supported and guided so as to be slidable in the vertical direction. Inside the operating frame 52, there is provided a hook 53 which is rotatably supported approximately at the center by the guide case 51 and whose one end (the upper end in FIG. 11) is formed into a hook shape. There is. This hook 53 is
It is usually constructed by stacking plate members punched into the same shape in the thickness direction (see Fig. 10).

A plate-shaped drive arm 54 is attached to the other end of the hook 53.
One end of the drive arm is linked, while the other end of the drive arm is pivotally connected to the operating frame 52.

Then, as shown in Fig. 10, the connecting frame 49
The drive pin 5 coupled to the rear interlocking rod 55 at
6 is integrally connected to the operating frame 52 so as to pass through it, and is guided so as to be movable in the vertical direction through elongated holes 57, 57 (see FIG. 11) opened in the side surface of the guide case 51. There is. Note that the rear interlocking rod 55 is connected to the corner deflection device 34.
(FIG. 8), it is connected to the upper interlocking rod 33.

On the other hand, a strike plate 59 as shown in FIG. 12 is provided in a so-called mullion 58 (the middle frame of the sash) that faces the connecting frame 49 when the sliding door advances to the door closing position. This strike board 5
9 is cut out to form a hook insertion hole 59a, and a locking portion of the strike plate is left below the hook insertion hole 59a. Further, one side end of the hook insertion hole 59a is bent inward to form an inclined surface 59b intersecting the vertical plane at an acute angle.

In the pulling mechanism configured as described above, when the handle HL is rotated after the sliding door has advanced to the door closing position, the rear interlocking rod 55 (Fig. 10) in the connecting stile 49 is pulled upward. With the above-described structure, the operating frame 52 is pulled upward in FIG. 11. As a result, the other end is connected to the operating frame 5.
One end of the driving arm 54 pivotally connected to the guide case 51 pulls the other end of the hook 53 upward along an arc, so that the tip of the hook 53 touches the mullion 5 of the guide case 51.
It is swung outward from the opening on the 8th side. If the sliding door collides with a stopper (not shown) and returns a little, the tip of this hook will be attached to the inclined surface 59b of the strike plate.
Due to the further rotation of the hook 53, the tip of the hook 53 slides relatively downward along the inclined surface 59b. In this case, the strike plate 59 is a mullion 5
8, the hook 53 is fixed on the inclined surface 59.
It receives a reaction force from b, and is pushed to the right in FIG. 12 and upward in FIG. 10 due to the wedge action. That is,
The sliding door is drawn to the other sliding door side. Of course, when the sliding door is at a predetermined position without returning, the tip of the hook 53 enters the hook insertion hole 59a without contacting the inclined surface 59b.

When the sliding door is completely drawn and the tip of the hook 53 disengages from the inclined surface 59b, the tip of the hook 53 comes into contact with the locking portion of the strike plate 59 from the back side,
When the hook 53 is swung out to the maximum as shown by the chain line in FIG.
8, and the connecting frame 49 is pressed against the packing strip 45 (see FIG. 10) fitted into the mullion.

Furthermore, a pulling mechanism as shown in FIG. 13 is provided at the lower end of the door stop stile 1 and the connecting stile 49 of the sliding door, and these pair of pulling mechanisms work together to move the lower part of the sliding door. Perform attraction.

That is, in FIG. 13, reference numeral 51 indicates a guide case having a rectangular cross section, and this guide case 51 is fixed to the lower end portions of the vertical frames 1 and 49. Inside the guide case 51, like the pulling mechanism shown in FIGS. 10 and 11, an operating frame 52 having a U-shaped cross section is supported and guided so as to be slidable in the vertical direction. This operating frame 52 is connected to the second interlocking rod 2 in the door stop stile 1 or the connecting stile 49 via a drive pin 56 similar to that described above (see FIG. 10).
5 or the lower end of the backward interlocking rod 55.

On the other hand, a kicking pawl block 61 is pivotably mounted to the lower end of the guide case 51, and a dogleg-shaped cam hole 61a opened in this kicking pawl block is implanted at the lower end of the operating frame 52. operating pin 62
are slidably engaged.

With the above configuration, when the handle lever HL of the sliding door is rotated when the door is closed, the interlocking rods of the door stop stile 1 and the connecting stile 49 are pulled up,
The operating frame 52 connected to the interlocking rods 25, 55 via the drive pin 56 also rises together with the operating frame 52, and the operating frame 5
The kick pawl block 61 rotates clockwise in FIG. 13 due to the wedge action caused by the engagement between the operating pin 62 implanted in the cam hole 61a and the upper half of the cam hole 61a. As a result, as shown by the chain line, the kick claw 61b formed at the lower end of the kick claw block moves to kick the side surface of the rail 63, and due to the reaction force from the rail 63, the lower part of the sliding door Packing strip 4 drawn to the right in the figure and attached to the lower frame of the sash
5 is crimped.

In addition, in the pulling mechanism shown in FIG.
Just by sliding the vertical part of the kick claw block 6
No external force is applied to 1, but the reason is that it is synchronized with the pulling operation that follows the drawing operation of the pulling mechanism (see FIGS. 10 to 12) having a drawing function in the gathering frame 49. For the sake of
This also applies to the pulling mechanism (see FIGS. 6 and 7) in the upper stile 36.

[Effect]

In the sliding door according to the present invention configured as described above, there are two sliding doors A and A1 (Fig. 1 and 2).
(see figure)), when sealing the sliding doors A and A at the same time.
1 and turn the handle lever HL of sliding door A clockwise and that of sliding door A1 counterclockwise by 180 degrees.

Then, due to the configuration of the handle devices B and B1 described above, the second interlocking rod 25 is pulled down, and on the other hand,
As a result of the third interlocking rod 32 being pulled up (see FIG. 3), the engaging portion C serving as the vertical groove is lowered, and the engaging portion D serving as the protruding shaft is raised, so that they approach each other.

In the middle of the mutual close movement of these engaging parts C and D, the pulling mechanisms at the upper stile 36, the joining stile 49, and the lower side of the sliding door begin to operate, and the two sliding doors A and A1 on the packing strip 45 side start to operate. The attraction to begins. When the phase angle difference between the two handle levers HL and HL is zero, the engaging portions C and D remain aligned in the expected direction of the sliding door and continue to approach each other, while at the same time closing the sealing strip 45.
The enlarged portion 31 formed at the top of the engaging portion D comes into contact with the inclined surface 30c formed on the inner surface of the open end of the box-like body 30. From this point on, as the engaging portions C and D approach each other further, the two sliding doors A and A1 move closer to each other due to the wedge action generated between the enlarged portion 31 and the inclined surface 30c. Attracted to the handle lever
When the HL and HL have been rotated 180 degrees, as shown in Figure 1, the door tip has been completely drawn, the tight members 6, 6 are in elastic contact with the edge of the door stop frame on the other side, and the door is closed. The sealing at the tip is airtight, and the drawing is also completed, so that the door opening is also airtightly sealed.

Note that the handle levers HL, HL may be operated by rotating the two handles simultaneously as described above, or may be performed sequentially at intervals over time.

For example, if you turn the handle of a sliding door A that has an engaging part C (vertical groove) first, as shown in FIG.
The engaging portion C descends by the amount of its travel stroke. At this time, since the sliding door A has been pulled, the fifth
As shown in the figure, the engaging portion C is deviated from the engaging portion (protruding shaft) D by a pulling amount β in the expected direction of the sliding door.

In this state, press the handle lever of the other sliding door A1.
When the HL is rotated, the vertical groove C and the lower end of the protruding edge 30a are expanded in a distal shape, so the protruding shaft D and the distal enlarged portion 31 are guided by the inclined edge 30d and the inclined inner surface 30e, respectively, and mutually Due to the wedge action that occurs between the protruding shaft D and the inclined edge 30d that slide into contact with the sliding door and/or the distal end enlarged portion 31 and the inclined inner surface 30e, the protruding shaft D is pushed so as to be introduced into the vertical groove C, and the sliding door The door stop stile 2 of A1 is drawn toward the indoor side. At the same time, the distal enlarged portion 31
a, 30a because it engages with the inclined surface 30c at the lower end,
The door stop frames are also attracted to each other, and at the same time as these door stop frames are pulled together and pulled together, other sides of the sliding door A1 are also pulled together, so that the door stop frames are eventually hermetically sealed together, and The sliding door is hermetically sealed against the sash.

When the handle lever HL of the other sliding door A1 having the protruding shaft D is turned first, the protruding shaft D is pulled first, so the handle lever of the one sliding door A is rotated.
By turning HL next time, the engaging part C (vertical groove)
is lowered, and this time, in FIG. 5, the right inclined edge 30d and the protruding shaft D engage, and the door stop frames 1 and 2 are pulled together and the sliding door A is pulled together in the same manner as described above. be exposed.

When closing the two sliding doors A and A1 in sequence, compared to the case where the handle levers HL and HL are sequentially turned after the sliding doors butt each other, the difference is that the sliding door butt operation is performed before the subsequent handle operation. Therefore, it is clear that the door stop frames and the sliding door sash frame are sealed in the same manner as described above.

In addition, there are two handle levers after the shoji butt.
The same applies when a phase angle difference occurs between the two handle levers when HL and HL are operated at the same time.

〔effect〕

As is clear from the above description, the present invention has an engaging part that moves up and down in conjunction with the operation of a handle attached to a sliding door stile, and a vertical stile or frame of the other sliding door that faces the sliding door stile. In a sliding door that is pulled in the forward direction by mutual engagement with the provided engaging parts, one of the engaging parts is formed as a protruding shaft with an enlarged tip, and the other engaging part is formed as a protruding shaft with a tip of the protruding shaft. It is formed as a vertical groove for inserting the ampullae, and a protrusion for locking the distal ampullae is provided on the vertical opening edge of the longitudinal groove for inserting the protruding shaft, so that they are close to each other when operating the handle lever. The door stop stile of the sliding door is pulled together by the mutual engagement of the protruding shaft with the tip enlarged part, the longitudinal groove, and the tip bulge locking ridge, and the door stop stile and the other sliding door opposite thereto are pulled together. The doorstop or the sash frame is reasonably attracted to the doorstop stile or the sash frame, regardless of the order in which the sliding door moves to close the door or the order in which the handle levers of the sliding door are operated. This has the effect of ensuring airtight sealing between the door and the sliding door, making the sliding door more convenient to use.

[Other Examples] Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications.

For example, the present invention can also be applied to a so-called single-pull door that opens and closes a single sliding door. In this case, as shown in FIG. 14, an engaging portion D as a protruding shaft is provided in a portion of the fixed vertical sash frame 64 facing the edge of the sliding door A, while a movable sliding door A is provided. An engaging portion C is provided at the edge of the door stop stile 1. The mutual positional relationship of these engaging parts C and D is as follows:
