This works by interlocking the pulling mechanism installed on the inner and outer sliding door shoji, and also presses the vertical frame of the sliding door shoji against the vertical frame of the sash frame in which the sliding door shoji is built. be.

(Prior Art) Sliding doors as shown in FIG. 14, for example, are widely used to open and close openings in general houses and the like.
This sliding door consists of an upper frame 1, a lower frame 2, left and right vertical frames 3,
3 and 3 are assembled into a rectangular shape inside the sash frame 4,
Two sliding door shoji 5a and 5b, inside and outside, are built in such a way that they can be moved freely over the length direction of the upper and lower frames 1 and 2, respectively. The double sliding door shoji 5a and 5b have upper frames 6a and 6b, lower frames 7a and 7b, and a vertical frame 8 that faces the vertical frames 3 and 3 when the sliding door is closed.
a, 8b, and matching frames 9a, 9 that are parallel to the vertical frames 8a, 8b and face each other when the sliding door is closed.
b are combined into a rectangular shape, and glass is supported on the inner circumferential side of each frame. Each sliding door 5
Among the connecting frames 9a and 9b that constitute the windows a and 5b, the connecting frame 9a of the indoor sliding door shoji 5a has the 17th to
A crescent fitting 10 as shown in Fig. 19 is installed at the joining stile 9b of the outdoor sliding door shoji 5b, and a receiving fitting 11 as shown in Fig. 19 is provided in the portion facing the crescent fitting 10, respectively, to secure the sliding door. When closing, by rotating the lever 12 of the crescent fitting 10 to the closed state (the state shown in Figs. 17 to 19), the vertical wall 17 formed at the base end of the lever 12 enters the inside of the receiving fitting 11. The sliding doors can be locked.

The basic structure of the sliding door is as described above, but when closed, between each stile surrounding the four circumferences of each sliding door shoji 5a, 5b and each frame constituting the sash frame, and between the inside and outside sliding door shoji 5a, 5b. By maintaining airtightness between the connecting frames 9a and 9b, soundproofing inside and outside the sliding door is achieved. In order to achieve this purpose, packing for airtightness is attached to the surfaces of each stile and each frame that face each other when the sliding door is closed, and when the sliding door is closed, both the inside and outside sliding door shoji 5a, 5b are installed. By moving it a little parallel toward the indoor side, the packing is pressed between the stile and the frame.

For example, as shown in FIG. Attach packing 14, 14 over the entire length,
The vertical frame 8a facing the vertical frames 3, 3 when the sliding door is closed,
On the outer peripheral surface of 8b, there is provided the intermediate protrusion 13 (in the case of the indoor sliding door shoji 5a), or another protrusion 15 provided closer to the outdoors than the intermediate protrusion 13 (in the case of the outdoor sliding door shoji 5a).
In case b), the attracting block 16,1 collides with
6 is fixed. Each pulling block 16,1
The part that collides with each protrusion 13, 15 of 6 is the vertical stile 8.
As the outer peripheral surfaces of the frames a and 8b are approached, they are inclined toward the outdoor side, so when each sliding door shoji 5a and 5b is moved to the closed state, each vertical frame 8a and 8b is tilted toward the indoor side. Move parallel to this vertical stile 8a, 8
The indoor side surfaces of b are pressed toward the packings 14, 14 to maintain airtightness between each of the vertical frames 8a, 8b and the vertical frames 3, 3.

In addition, packing 18, as shown in FIG.
19 is provided, and when the sliding door is closed and the locking operation is performed using the crescent metal fitting 10, both the upper and lower frames 6a, 7a of the indoor sliding door shoji 5a are moved in parallel toward the indoor side, and both of the above-mentioned Stiles 6a, 7
A part of a is pressed against the packing 18, 18. At the same time, the crescent metal fittings 10
Due to the engagement of the bracket 11 with the connecting frame 9b,
The outdoor sliding door shoji 5b, which is inseparably connected to the joining frame 9a of the indoor sliding door shoji 5a, is moved parallel to the indoor side, and attached to the indoor side surfaces of both the upper and lower frames 6b, 7b of this outdoor sliding door shoji 5b. Packing set 1
9 and 19 are pressed against packings 18 and 18 attached to both the upper and lower frames 1 and 2. Further, since the vertical wall 17 of the crescent fitting 10 is formed so that its radius gradually becomes smaller so as to draw the outdoor side connecting frame 9b toward the indoor side connecting frame 9a when the lock is locked, the lever 12 By the locking operation accompanying the rotation of the sliding door shoji 5a on the indoor side,
The outdoor side of a and the outdoor sliding door shoji stile 9b
The distance from the indoor side surface of the connecting frame 9b becomes narrower, and the packings 20, 20 attached to the indoor side surface of the connecting frame 9b are pressed against the outdoor side surface of the connecting frame 9a.

The pulling mechanism that moves the joining frame 9a of the indoor sliding door shoji 5a in parallel toward the indoor side as the lever 12 of the crescent fitting 10 rotates is configured, for example, as shown in FIGS. 20 to 22. However, the crescent fitting 10 used for this pulling mechanism has
As shown in FIG. 18, two upper and lower pins 21a and 21b are provided that move up and down as the lever 12 rotates, and lifting rods 22a and 22b (20th to 22nd (Fig.),
It is designed to drive a pulling mechanism.

That is, the two pins 24a, 2 formed on the rotating body 23 that interlocks with the lever 12 of the crescent fitting 10
4b denotes two upper and lower elevating plates 26a and 26 that are installed in the base 25 of the crescent fitting 10 so as to be able to rise and fall freely.
The pins 21 are fitted into elongated holes 27a and 27b, which are long in the front and back directions in FIG.
a and 21b are planted respectively. Since the crescent fitting is configured in this way, when the rotating body 23 rotates with the rotation of the lever 12, this rotating body 2
The upper and lower two elevating plates 2 are placed within the range in which the pins 24a and 24b of No. 3 can move within the elongated holes 27a and 27b.
6a and 26b move up and down. For this reason, each elevating plate 26
Pins 21a, 21 provided at the ends of a, 26b
b is located at the chain line position in FIG. 18 when the lever 12 is rotated to the unlocked state, and moves to the solid line position in the same figure when the lever 12 is rotated to the locked state. For this reason, when the lever 12 of the crescent fitting 10 is moved from the unlocked position to the locked position,
Lifting rod 22a whose lower end is connected to the upper pin 21a
is pushed up inside the connecting frame 9a, and the lower pin 2
The lifting rod 22b whose upper end is connected to 1b is the connecting rod 9.
The inside of b is pushed down.

Pulling blocks 28a and 28b are fixed to the upper end of the upper lifting rod 22a and the lower end of the lower lifting rod 22b, respectively. Pulling block 28 fixed to the upper end of the upper lifting rod 22a
The outdoor surface of the upper end of the upper end of a is an inclined surface that slopes toward the indoor side as it goes upward, and the outdoor surface of the lower end of the pull block 28b fixed to the lower end of the lower lifting rod 22b slopes toward the indoor side as it goes downward. Each inclined surface can collide with the lower end indoor side edge of the upper guide rail 29 formed on the lower surface of the upper frame, or the upper end indoor side edge of the lower guide rail 30 formed on the upper surface of the lower frame. There is. Therefore, when the upper drawing block 28a is raised and the lower drawing block 28b is lowered as the lever 12 is rotated in the locking direction, both the inclined surfaces and the upper and lower guide rails 2
Due to the collision with the indoor side edges of 9 and 30, the stile 9
Both the upper and lower ends of b are drawn toward the indoor side.

(Problems to be Solved by the Invention) However, the conventional sliding door pulling mechanism constructed and operated as described above has the following disadvantages.

That is, the vertical frames 8a, 8b of each sliding door shoji 5a, 5b
In order to sufficiently effectively press the side surfaces of the room against the packings 14, 14 attached to the left and right jambs 3, 3,
It is necessary to move each sliding door shoji 5a, 5b to a completely closed position.

However, it is not always easy to move the sliding door shoji 5a, 5b to the completely closed position.
A gap larger than a predetermined amount exists between the outer surfaces of the stiles 8a, 8b and the inner surfaces of the jambs 3, 3, and the pulling blocks 16, 16 press the stiles 8a, 8b against the packings 14, 14. is insufficient and it is a victory.

In addition, when focusing on the case where the outdoor sliding door shoji 5b is drawn toward the indoor side, among the matching frames 9a and 9b of each sliding door shoji 5a and 5b, the matching stile 9a of the indoor sliding door shoji 5a is located at both upper and lower ends. Although it is drawn toward the indoor side, the sliding door shoji 5b on the outdoor side
b is drawn toward the joining stile 9a of the indoor sliding door shoji 5a only by the engagement of the crescent fitting 10 and the receiving metal fitting 11 provided at the intermediate part of both the outside and outside joining stile 9a, 9b. There is.

If the sliding door is installed in an opening with a small height, such as a waist window, and the connecting stile 9b is thick and has sufficient rigidity, this will not be a particular problem, but if the sliding door is It is installed in a large opening such as a bay window, and
If b is thin and has low rigidity, by curving this connecting frame 9b, the inner and outer connecting frames 9
The airtightness between a and 9b becomes incomplete.

If the crescent metal fittings 10 and the receiving metal fittings 11 are provided not only at the middle part of the frames 9a and 9b but also at both the upper and lower ends, such inconvenience will not occur, but locking and unlocking of the sliding door will become troublesome. I don't like it. This is true not only in the case of double sliding doors, but also in the case where only one sliding door shoji is provided and the crescent fitting 10 that engages with the receiving fitting 11 of this sliding door shoji is provided on the side of the mullion. It is.

In order to eliminate the above-mentioned inconvenience,
Publication No. 18127 states that this connecting frame 9 is not included in any of the connecting frames 9a and 9b of both the interior and exterior sliding door shoji 5a and 5b.
A and 9b are provided with a mechanism for drawing them toward the indoor side, and a mechanism is provided between the two connecting frames 9a and 9b to interlock the two mechanisms, and based on the locking operation, the internal and external sliding door shoji 5a and 5b are distributed to the left and right, Each sliding door 5
A mechanism for bringing the vertical stiles 8a, 8b of the sash frames 4 closer to the vertical stiles 3, 3 of the sash frame 4 is described.

However, the mechanism described in the above-mentioned publication has a structure in which the component part provided on the indoor side connecting frame 9a and the component part provided on the outdoor side connecting frame 9b when the sliding door shoji 5a, 5b are closed. The engagement is not necessarily complete, and when the sliding door shoji is locked, the two components may become disengaged, causing the two mechanisms to malfunction.

The sliding door shoji sealing device of the present invention is as follows:
By configuring the structure so that the vertical stile of the sliding door shoji is pressed against the jamb of the sash frame in one movement, and the sliding stile on the side where the crescent metal fittings are not installed is moved in parallel, the above-mentioned This will eliminate any inconvenience.

b. Structure of the invention (Means for solving the problem) The sliding door shoji of the invention has a sealing device installed inside the sash frame, which is made up of an upper frame, a lower frame, and left and right vertical frames, just like conventional sliding doors. The sliding door shoji is surrounded by an upper stile, a lower stile, and vertical stile on the left and right, and is movable along the upper and lower frames.

Inside the vertical stile of the sliding door shoji, which forms a matching stile that faces other stile-like members when closed, and the vertical stile-like member, there is a pulling mechanism for pulling each sliding door shoji toward the indoor side. There are first and second vertically movable lifting rods that drive the. In the middle of the first elevating rod, which is provided inside the first vertical member of one of the connecting stile and the vertical stile-like member, and which moves up and down in conjunction with the movement of the crescent fitting for locking the sliding door shoji, , a drive side block whose part aligns with a first long hole elongated in the vertical direction formed in the side surface of the first vertical member facing the other second vertical member of the joining frame and the vertical frame-like member; A second vertically elongated hole formed in the side surface of the second vertical member facing the first vertical member is inserted in the middle of the second lifting rod that is fixed and provided inside the second vertical member. A partially aligned driven block is fixed.

On one side of both the driving side and driven side blocks, an engaging pin is fixedly installed in a portion aligned with the first and second elongated holes, and on the other side of both the driving side and driven side blocks, the above-mentioned When the sliding door shoji is closed, the vertically long engagement recess formed in the receiving part fixed to the first and second elongated holes can be freely engaged with the recessed part, and when the sliding door shoji is closed, The second lifting rod can be moved up and down in conjunction with the vertical movement of the first lifting rod.

Further, a roller having a flange-shaped portion at its tip is pivotally supported on one side of the joining stile and the vertical stile-like member, and is fitted onto the other side of the joining stile and the vertical stile-like member. On the side surface of the driven side or driven side block, a portion aligned with the first and second elongated holes is formed by colliding with the outer circumferential surface of a portion closer to the proximal end than the inward flange-shaped portion of the roller. A plate-shaped abutting piece having an inclined edge for relatively moving the vertical stile forming the joining stile and the vertical stile-like member toward the closing direction of the sliding door is fixed.

(Function) In the sliding door shoji sealing device of the sliding door of the present invention configured as described above, by moving the sliding door shoji to the closed state and operating the crescent fitting, the inside of the first vertical member is closed. When the first lifting rod is raised and lowered, the driving block fixed to the first lifting rod is raised and lowered, and the driven block, which engages the driving block in a concave and convex manner, is raised and lowered, and the driven block is fixed. A second lifting rod moves up and down inside the second vertical member.

As a result, both the first and second lifting rods provided inside the first and second vertical members can be raised and lowered simultaneously by operating the single crescent fitting,
Due to the movement of each lifting rod, both the upper and lower ends of the connecting stile of the sliding door shoji that are not provided with crescent fittings are also pulled toward the indoor side.

Also, due to the collision between the roller supported by a pivot installed on one side of the connecting stile and the vertical stile-like member and the inclined edge formed on the abutment piece, the vertical stile forming the connecting stile and , the stile-like member moves relatively toward the closing direction of the sliding door. At this time, the flange-like part formed at the tip of the roller and the plate-shaped abutting piece engage with each other so that the connecting stile and the vertical stile-like member do not separate from each other, and the roller and the abutting piece It acts to ensure that the engagement with the piece and the engagement between the engagement pin and the receiving portion are performed reliably.

(Example) Next, the present invention will be explained in more detail while explaining the illustrated embodiment.

Figures 1 to 5 show a first embodiment in which the present invention is applied to a sliding door. Figure 1 is a front view, and Figure 2 is a front view.
The figure is a left side view showing the receiver and the abutment piece fixed to the outdoor side surface of the driving side block, FIG. 3 is a right side view showing the roller and engagement pin attached to the indoor side surface of the driven side block, and FIG. 4 is an AA view of FIG. 1, and FIG. 5 is a BB view.

On the inside of the matching frame 9a of the indoor sliding door shoji 5a, the levers 12 (17th to
The first lifting rod (see FIG. 19) moves up and down in conjunction with the rotation of the first lifting rod (see FIG. 19), and drives the pulling mechanism (see, for example, FIG. Lifting rods 22a and 22b shown in Figure 19
and something similar. ) is fitted so that it can move only in the vertical direction, and in the middle of this elevating rod,
A drive side block (not shown) made of a slippery hard material such as nylon is fixed.

A first elongated hole 31 that is long in the vertical direction is formed in the outdoor side surface of the joining frame 9a where the drive side block faces, and a first elongated hole 31 that is long in the vertical direction is formed in the outdoor side surface of the drive side block. This bracket 33 is formed by bending a metal plate having sufficient rigidity at a position aligned with the hole 31, and has a receiving portion 37 and an inclined edge 40b, and is fixed by screws 34, 34. It is movable up and down inside the first elongated hole 31.

The bracket 33 is attached to a base plate 3 fixed to the outdoor side surface of the drive block by screws 34, 34.
5 lower one side edge (center side edge of sliding door shoji 5a)
By bending the lower leg piece 3 at a right angle toward the outdoor side,
6, and by bending both the upper and lower ends of the outdoor side edge of the lower leg piece 36 at right angles toward the upper side of the base plate 35, an upper abutment piece 37a and a lower abutment piece 37a are formed. A receiving part 3 for inserting a pin 32, which will be described later, between the abutting pieces 37a and 37b.
It is set at 7.

On the other hand, at the upper part of the base plate part 35 constituting the bracket 33, the edge part located on the outer peripheral side of the joining frame 9a of the indoor sliding door shoji 5a is bent at a right angle toward the outdoor side to form an upper leg piece 38. By bending the outdoor end edge of this upper leg piece 38 at a right angle toward the upper side of the base plate part 35, it forms an abutment piece 40 that abuts against a roller 39, which will be described later.

The lower part 40a of this abutting piece 40 is inclined in the direction away from the base plate part 35 as it goes towards the lower end, and the inner edge of the lower part 40a of this inclined abutting piece 40 is aligned with the connecting frame 9a as it goes towards the lower end. The inclined edge 40b is directed outward.

On the other hand, a pivot 41 is installed on the indoor side surface of the joining frame 9b of the outdoor sliding door shoji 5b, and a roller 39 made of a slippery material such as nylon is pivotally supported on this pivot 41. . At the tip of the roller 39, which is pivoted at a position where the outer circumferential surface abuts the inclined edge 40b when the driving block is lowered,
A flange-like portion 39a is formed.

Also, the outdoor sliding door shoji 5b moves up and down within the matching stile 9b at a position aligned with the second elongated hole 42 formed on the indoor side surface of the matching stile 9b, and as it moves up and down, the matching stile 9b A pin 32 is installed on the indoor side surface of a driven block (not shown) that drives the pulling mechanism provided at both the upper and lower ends of the
can be raised and lowered inside the second elongated hole 42.

The bracket 33 fixed to the outdoor side surface of the drive side block and the pin 32 installed on the indoor side surface of the driven side block are connected to both the inside and outside sliding door shoji 5a, 5b.
When the pin 32 on the driven side block side is installed inside the sash frame (Fig. 14), the drive side block and Adjust the height with the driven block.

For this reason, when both the interior and exterior sliding door shoji 5a, 5b are moved to the closed state and the lever of the crescent metal fitting is rotated in the locking direction, a When the first lifting rod is lowered, this movement is controlled by a bracket 33 fixed to the drive side block and a pin 32 installed in the driven side block, which is installed inside the connecting frame 9b of the outdoor sliding door shoji 5b. The signal is also transmitted to the second elevating rod, and the elevating rods provided inside both the inner and outer sliding door shoji 5a, 5b simultaneously lower.

In this way, the upper and lower ends of both the first and second lifting rods, which descend in synchronization, are connected to the connecting frame 9 of the sliding door shoji 5a, 5b on the indoor side and the outdoor side, respectively.
The pulling mechanisms provided at a and 9b are driven to pull both of the connecting frames 9a and 9b towards the indoor side.

At the same time as above-mentioned drawing of both the inside and outside sliding door shoji 5a, 5b towards the indoor side, or prior to the drawing,
A so-called drawing operation is performed in which the vertical frames 8a, 8b (FIGS. 14 and 15) of the sliding door shoji 5a, 5b are pressed against the vertical frames 3, 3 of the sash frame 4.

That is, when the bracket 33 is lowered with the lowering of the drive side block, this bracket 33
The inclined edge 40b of the abutting piece 40 formed on the upper part of the
The connecting frame 9b of the outdoor sliding door shoji 5b collides with the roller 39 pivoted on the indoor side surface, and by wedge action, the connecting frame 9b is moved in the direction of closing the outdoor sliding door 5b (Figs. 4 and 5). (downward). As a reaction to this, the joining frame 9a of the indoor sliding door shoji 5a that houses the drive block to which the bracket 33 is fixed also moves in the direction in which the indoor sliding door shoji 5a is closed (the fourth direction).
5), the sliding door shoji 5 on both the inside and outside
The vertical frames 8a, 8b of a, 5b are all pressed toward the vertical frames 3, 3 (FIGS. 14 and 15) of the sash frame 4.

Lower part 40 of the abutment piece 40 forming the inclined edge 40b
a is inclined so as to move away from the base plate part 35 toward the lower end, so that when the drive side block starts to descend, the distance between the inner and outer connecting frames 9a and 9b is in the indoor and outdoor directions (left and right in Figs. 4 and 5). Even if the lower part 40a and the brim portion 39a are engaged with each other, the outer circumferential surface of the roller 39 and the inclined edge 40b
The collision will definitely take place.

In addition, such drawing work is performed after both the interior and exterior sliding door shoji 5a, 5b are drawn toward the indoor side.
Each upper and lower frame 6 that constitutes the above-mentioned double sliding door shoji 5a, 5b
Since this becomes difficult due to friction between a, 6b, 7a, 7b and the packing 18, 18, the receiving part 3 is
7. It is preferable to determine the positional relationship of the pin 32, roller 39, and abutment piece 40. In this case, when the pin 32 and the upper abutment piece 37a constituting the receiving part 37 abut each other and the driven block on which the pin 32 is installed descends, the circumferential surface of the roller 39 is a vertical edge 40 that continues above the inclined edge 40b.
c, so the inner and outer sliding door shoji 5a, 5b are not forced to separate left and right any further. In this state, the flange-shaped part 39a formed at the tip of the roller 39 prevents the inner and outer joining frames 9a, 9b from separating by engaging with the vertical edge 40c, and during the pulling operation, the flange-shaped part 39a is formed at the tip of the roller 39. 33 receiving part 37
This prevents the pin 32 from being accidentally disengaged from the engagement with the pin 32.

In addition to the mechanism shown in Figs. 20 to 22, the mechanism for pulling each joining frame toward the indoor side as the lifting lever to which both the driving side and driven side blocks are fixed is lowered can be of various conventionally known structures. can be adopted.

Next, FIGS. 6 to 9 show a second embodiment of the present invention. In the case of this embodiment, in order to reduce the height of the bracket 33 fixed to the outdoor side surface of the drive side bracket, an abutting piece 40 having an inclined edge 40b is provided on the side of the receiving part 37. Further, the receiving portion 37 is made by injection molding of synthetic resin.
A part of the metal plate constituting the abutment piece 40 is inserted into the synthetic resin constituting the abutment piece 40.

The other configurations and operations are substantially the same as those of the first embodiment described above, so the same parts are given the same reference numerals and redundant explanations will be omitted.

Furthermore, FIGS. 10 to 13 show a third embodiment of the present invention. In this embodiment, both the inside and outside sliding door shoji 5a,
Inner and outer folding frame 9 during pulling work of 5b
In order to ensure prevention of separation of the sliding door shoji 5b, this is a further improvement of the second embodiment described above, in which the roller 39 pivotally supported on the indoor side of the outdoor sliding door shoji 5b is held from both sides during the pulling operation. It is composed of

That is, the metal plate constituting the abutting piece 40 is formed wider than that of the second embodiment, and one side of the inverted U-shaped notch formed in the metal plate continues above the inclined edge 40b. It has a vertical edge 40c. The distance between the vertical edge 40c and the straight edge 43 parallel to the vertical edge 40c is slightly larger than the outer diameter of the base of the roller 39.
The straight edge 43 and the vertical edge 40b are made sufficiently smaller than the outer diameter of the flange-like portion 39a formed at the tip of the flange.
The roller 39 that has entered between the flange-like part 39 can move up and down inside the inverted U-shaped notch.
The presence of a prevents the abutting piece 40 and the pin 32, which are in an engaged state, from separating in the indoor-outdoor direction.

At the edge of the abutment piece 40 located on the opposite side to the synthetic resin constituting the receiving part 37, there is a bent piece 44 having an L-shaped cross section formed on the outdoor side of the indoor side joining stile 9a.
If a force is applied to the inner and outer connecting frames 9a, 9b in the direction of separating them from each other when the abutment piece 40 and the roller 39 are engaged, the abutment piece 40 is prevented from being pulled in the outdoor direction. This is prevented not only by the screws 34, 34 fixing the receiving part 37, but also by the bent piece 44. Other configurations and operations are the same as in the first and second embodiments described above.

Note that the sliding door provided with the sliding door shoji sealing device of the present invention is not limited to a sliding door as in the illustrated embodiment, but is a sliding door in which a single sliding door shoji is moved inside a sash frame, and a crescent metal fitting is attached to the sliding door. Even when the sliding door shoji is provided with a connecting mullion fixed to the sash frame instead of a connecting frame, the connecting frame can be pulled together using the same structure.

c. Effects of the invention Since the sealing device for the interior and exterior sliding door shoji of the sliding door of this invention is configured and operates as described above, it is possible to draw not only the indoor side but also the joining frame of the outdoor sliding door shoji sufficiently strongly toward the indoor side. This makes it possible to sufficiently maintain airtightness at both the upper and lower ends of the stile, and moreover, the locking operation can be performed in one movement as in the conventional case.
