[Detailed description of the invention] a. Purpose of the invention (industrial application field) The sliding door shoji pulling device according to this invention is a device for moving sliding door shoji to the closed state for opening and closing window openings in general houses. When this is locked, the sliding door shoji is pulled toward the indoor side in conjunction with the locking operation, pressing down on the packing between the stile that surrounds the sliding door shoji and the sash frame in which the sliding door shoji is built,
This allows for good airtightness to be maintained indoors and outdoors, and is effective when applied to large sliding door shoji screens.

(Prior Art) Sliding doors as shown in FIG. 6 are widely used to open and close openings in general houses and the like. This sliding door has two inner and outer sliding door shoji 5a, 5b inside a sash frame 4 made up of a rectangular upper frame 1, a lower frame 2, and left and right vertical frames 3, 3, respectively. It is built in such a way that it can be moved freely along the length of the building. The double sliding door shoji 5a, 5b are respectively upper stile 6a, 6b, lower stile 7a, 7b, and vertical stile 8 which faces the vertical frames 3, 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. Among the matching frames 9a, 9b that constitute each sliding door shoji 5a, 5b, a crescent fitting 10 as shown in FIGS. 7 to 9 is attached to the matching frame 9a of the indoor sliding door 5a, and In the connecting frame 9b, a receiving metal fitting 11 as shown in FIG. ~ the state shown in Figure 9).
A standing wall 17 formed at the base end of this lever 12 is inserted into the inside of the receiving metal fitting 11, so that the sliding door 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 installed on the faces 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 are placed on the indoor side. By slightly moving parallel toward the stile, the packing is pressed between the stile and the frame.

For example, as shown in FIG. A vertical stile 8 with packing 14, 14 attached over the entire length and facing the vertical frames 3, 3 when the sliding door is closed.
On the outer peripheral surfaces of a and 8b, 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 5b) ) colliding with the pulling block 16,
16 is fixed. Each pulling block 16,1
The part that collides with each of the protrusions 13 and 15 of 6 is the vertical stile 8.
Each sliding door shoji 5a, 5b has an inclined surface facing toward the outdoor side as it approaches the outer peripheral surface of the sliding door shoji 5a, 5b.
When moved to the closed state, each vertical stile 8a, 8
b moves in parallel toward the indoor side, and this vertical stile 8
Packing the indoor side surfaces of a and 8b with the packing 14, 14
Press toward each vertical stile 8a, 8b and vertical frame 3, 3.
maintain airtightness between

In addition, packing 1 as shown in FIG.
8 and 19, and when the sliding door is closed and the locking operation is performed using the crescent fitting 10, both the upper and lower frames 6a, 7a of the indoor sliding door shoji 5a
is moved in parallel toward the indoor side, and the above-mentioned frames 6a,
A part of 7a is pressed against packing 18, 18. At the same time, due to the engagement of the crescent metal fitting 10 and the receiving metal fitting 11, the outdoor sliding door shoji 5b, which has been unfavorably joined to the fitting frame 9b of the indoor sliding door shoji 5a, is moved indoors. It is moved in parallel inward, and the packing 19, 19 attached to the indoor side surfaces of both the upper and lower frames 6b, 7b of this outdoor sliding door shoji 5b are pressed against the packing 18, 18 attached to the upper and lower frames 1, 2. ing. Furthermore,
The vertical wall 17 of the crescent fitting 10 is formed so that its radius gradually decreases so that when the lock is locked, the outdoor side connecting frame 9b is drawn toward the indoor side connecting frame 9a. Due to the locking operation accompanying the movement, the distance between the outdoor side surface of the connecting frame 9a of the indoor sliding door shoji 5a and the indoor side surface of the connecting frame 9b of the outdoor sliding door shoji becomes narrower, and the indoor side surface of the connecting frame 9b narrows. Packing 2 attached to
0 and 20 are pressed against the outdoor side surface of the joining frame 9a.

The pulling mechanism that moves the joining frame 9a of the indoor sliding door shoji 5a in parallel to the indoor side with the rotation of the lever 12 of the crescent fitting 10 is, for example, a first
2 to 14, the crescent fitting 10 used in this pulling mechanism has two upper and lower pins 21a that move up and down as the lever 12 rotates, as shown in FIG. , 21b are provided, and lifting rods 22a and 22b (FIGS. 12 and 14), one end of which is connected to the pins 21a and 21b,
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 24a, 24b are fitted into elongated holes 27a, 27b, which are long in the front and back directions in FIG.
24b 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 2
Pins 21a, 2 provided at the ends of 6a, 26b
1b is located at the chain line position in FIG. 8 when the lever 12 is rotated to the unlocked state, and moves to the solid line position in the figure when the lever 12 is rotated to the locked state. Therefore, when the lever 12 of the crescent fitting 10 is moved from the unlocked position to the locked position, the elevating rod 22a whose lower end is connected to the upper pin 21a is pushed up inside the connecting frame 9a, and is pushed up into the lower pin 21b. The lifting rod 22b with its upper end connected is pushed down inside the joining frame 9b.

A pulling block 2 is provided at the upper end of the upper lifting rod 22a and the lower end of the lower lifting rod 22b.
8a and 28b are fixed. Upper lifting rod 2
The upper end of the pulling block 28a fixed to the upper end of the pulling block 28a has an inclined surface that slopes toward the indoor side as it goes upward, and the lower end of the pulling block 28b fixed to the lower end of the lower lifting rod 22b The outdoor side is
The slope slopes towards the indoor side as it goes downwards.
Each slope is an upper guide rail 2 formed on the lower surface of the upper frame.
9 or the upper end of the lower guide rail 30 formed on the upper surface of the lower frame. Therefore, when the upper pulling block 28a is raised and the lower pulling 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 are connected to the indoor side. Due to the collision with the edge, both upper and lower ends of the stile 9a are drawn toward the indoor side.

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

That is, when looking at the sliding door shoji 5a, the vertical stile 8a has pulling blocks 16 provided at multiple locations above and below the outer peripheral surface.
Therefore, the connecting stile 9a has both upper and lower guide rails 2.
Pulling blocks 28a, 28 that collide with 9, 30
The upper and lower stiles 6a and 7a, both ends of which are connected and supported by the vertical stile 8a and the joining stile 9a, are drawn toward the indoor side by the vertical stile 8a and the joining stile 9a.
The intermediate portions of the upper and lower frames 6a, 7a are pressed toward the upper frame 1 or the lower frame 2 of the sash frame 4 based on their rigidity. .

The width of the sliding door shoji 5a is small, and both the upper and lower frames 6
If a and 7a are thick and have sufficient rigidity, there is little problem, but sliding door shoji 5
If the width of a is large and the rigidity of both the upper and lower frames 6a, 7a is small, the pressing force of the packing 18 (Fig. 11) will be insufficient in the middle part of both the upper and lower frames 6a, 7a, and the sliding door shoji 5a and Airtightness between the sash frame 4 and the sash frame 4 will be incomplete.

The pulling device for a sliding door shoji of the present invention is configured to pull not only the vertical stile and the matching stile of the sliding door shoji, but also the intermediate portion between the upper and lower stile to the indoor side. In this way, the pressing force of the packing at the intermediate portion of both the upper and lower frames is sufficiently maintained, and the above-mentioned disadvantages are solved.

b. Composition of the invention (means for solving the problem) In the sliding door shoji pulling device of the invention, the upper guide rail on the lower surface of the upper frame or the lower guide rail on the upper surface of the lower frame moves upward toward the end. The base end of the swinging arm, which has an oblong hole inclined in a direction away from the side surface, is pivoted to the middle part of the upper stile or the lower stile by a vertical shaft.

The tip of this swinging arm is formed with a bent part that faces the indoor side surface of each of the guide rails, so that when the swinging arm rotates about the vertical axis, the bent part is formed inside the guide rail. It is made to collide with the sides.

On the other hand, the upper stile or the lower stile is provided with a horizontally movable member that is movable along each stile, and a pin that is driven based on the movement of the horizontally movable member is attached to an inclined length formed on the swing arm. It matches the hole.

Furthermore, it is provided on the matching member so as to be movable up and down,
The end of the lifting rod that is linked to the movement of the locking crescent and the end of the horizontally moving member are connected by a transmission device that converts the moving direction to a right angle, and the horizontally moving member is moved based on the movement of the locking crescent. is moving.

(Function) The pulling device for sliding door shoji of the present invention is constructed as described above, but when the sliding door shoji is in the closed state and the crescent is rotated to the locked state, the drawing member provided with the crescent will move. Inside, a lifting rod moves vertically, and a horizontally moving member connected to the end of the lifting rod via a transmission device moves horizontally along the upper stile or the lower stile.

When the horizontally moving member moves in this way, the pin driven based on the movement of the horizontally moving member moves toward the tip of the swinging arm inside the oblique elongated hole formed in the swinging arm. The swinging arm is rotated about the vertical axis in a direction in which its tip moves toward the indoor side of the upper or lower guide rail, and the bent portion formed at the tip of the swinging arm is brought into contact with the indoor side of the guide rail. and press this guide rail toward the outdoor side.

Since the guide rail does not move relative to the stile on which it is installed, the swinging arm moves toward the indoor side as a reaction to the pushing force, and a vertical shaft is provided that pivots the swinging arm. The upper or lower stile is pulled toward the interior.

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

1 to 3 show an embodiment of the invention.

A bracket 31 in the form of a curtain rail, which is made by bending a metal plate into a substantially C-shaped cross section and is open at the bottom, is fixed to the middle lower surface of the lower stile. The base end portion of the swing arm 33 is pivotally supported.

The middle part of this swinging arm 33 has a tip part (vertical shaft 3
An oblique elongated hole 34 is formed which is inclined in a direction away from the indoor side surface (the right side surface in FIG. 3) of the lower guide rail 30 on the upper surface of the lower frame as it goes toward the opposite end of the pivot portion (2).

Further, the tip of the swinging arm 33 has a bent portion 3 that faces the indoor side surface of the lower guide rail 30.
5 is formed. This bent portion 35 abuts against the indoor side surface of the lower guide rail 30 when the swinging arm 33 rotates about the vertical shaft 32, and as a reaction, a force is applied to the vertical shaft 32 toward the indoor direction. is added.

On the other hand, the lower stile 7a of the sliding door shoji 5a that moves horizontally along the lower guide rail 30 is provided with a horizontally moving member 36 that is movable along the lower stile 7a.

A push-pull plate 37 is fixed to the tip of the horizontally moving member 36 (the right end in FIGS. 1 and 2) with screws 38, and a pin 39 is implanted on the upper surface of the tip of the push-pull plate 37. are doing. This pin 39
The lower stile 7a is loosely engaged with the oblique long hole 34 formed in the swing arm 33, and the lower stile 7a is fitted inside the oblique long hole 34.
can be freely moved in the length direction.

Furthermore, the ends of the elevating rods 22b (FIG. 12), which are vertically movably provided on the joining frame 9a of the sliding door shoji 5a and are linked to the movement of the locking crescent, and the ends of the horizontally moving member 36 are , are connected by a transmission device that converts the direction of movement to a right angle, so that the horizontal movement member 36 moves in the horizontal direction based on the movement of the locking crescent.

In the sliding door shoji pulling device of the present invention constructed as described above, when the sliding door shoji 5a, 5b are in the closed state and the crescent is rotated to the locked state, the sliding door shoji 5a's connecting frame The lifting rod 22b is lowered inside the lower half of 9a, and this lifting rod 22b
A horizontally moving member 36 coupled to the end of the frame 7a via a transmitting device horizontally moves along the lower stile 7a in the right direction in FIGS. 1 and 2.

When the horizontally moving member 36 moves in this way, the pin 39 implanted on the top surface of the end of the push-pull plate 37 fixed to the distal end of the horizontally moving member 36 moves into the inclined elongated hole 34 formed in the swinging arm 33. Inside, swing arm 3
3 (to the right side in Figures 1 and 2).

As described above, the inclined elongated hole 34 is inclined so that the tip thereof is away from the indoor side surface of the lower guide rail 30 when the crescent is in the unlocked state, so that the pin 39 can move. Accordingly, the swing arm 33 rotates counterclockwise in FIG. 2 about the vertical shaft 32.

Along with this rotation, the outdoor side surface of the bent portion 35 formed at the tip of the swinging arm 33 abuts against the indoor side surface of the lower guide rail 30, and the lower guide rail 30 is moved to the outdoor side (upper side in FIG. 2). , left side in Figure 3).

Since the lower guide rail 30 does not move relative to the lower stile 7a fixed to the building, the swinging arm 33 moves toward the indoor side as a reaction to the pressing force.
The lower stile provided with the vertical shaft 32 on which the swinging arm 33 is pivoted is drawn toward the indoor side.

In addition, as the lever 12 of the crescent fitting 10 rotates, the end of the lifting rod 22b moves vertically inside the joining frame, and the end of the horizontal moving member moves horizontally inside the lower frame 7a. horizontally moving member 3 by converting the vertical movement of the lifting rod by 90 degrees.
The transmitting device for transmitting the signal to 6 may have various shapes and structures. For example, a flexible transmission member such as a leaf spring is installed inside an L-shaped hollow housing.
A transmitting device can also be constructed by connecting the lower end of the lifting rod to one end of the flexible transmitting member exposed from the housing, and connecting the other end of the flexible transmitting member to one end of the horizontally moving member.

As for the structure of the transmitting device, it is also possible to use a toggle mechanism as shown in FIG. 4, or a bell crank as shown in FIG. 5.

Of these, the transmission device using the toggle mechanism shown in FIG. 4 will be explained first. The lifting rod 22b (the third 12,
The upper end base of a push-pull bracket 40 is fixed to the lower end of the push-pull bracket 40 (see FIG. 14) with screws 41, 41. A horizontally long elongated hole 42 is formed at the lower end of the push-pull bracket 40.
This elongated hole 42 has first and second arms 43, 44.
An intermediate shaft 45 rotatably connects the two to each other. The first, connected by this intermediate shaft 45,
The second arms 43 and 44 constitute a toggle mechanism, and the end of the first arm 43 is attached to a shaft 48 on a support bracket 47 fixed to the lower end of the joining frame 9a with screws 46 and 46. It is supported by

The end of the second arm 44 is pivotally supported by a shaft 49 on a connecting bracket 50, and this connecting bracket 50 is connected to the lower frame 7a by screws 51, 51.
It is connected and fixed to the end of a horizontally moving member 36 provided in FIGS. 6 and 11. Therefore, when the lifting rod 22b descends as the crescent fitting rotates to the locked state, the intermediate shaft 45 is pushed downward via the push/pull bracket 40, causing it to bend as shown in FIG. The first and second arms 43 and 44 that were in the state extend straight and the connecting bracket 50
The horizontal moving member 36 is pushed in the direction of the arrow a in FIG. 4 through the horizontal movement member 36, the pin 39 moves within the oblique elongated hole 34, and the lower stile is drawn towards the indoor side.

In addition, in the transmission device using a bell crank shown in FIG. 5, a lifting rod 22b is provided inside the connecting frame 9a so as to be movable up and down, and moves up and down in conjunction with the movement of the crescent fitting for locking. The upper end base of a push-pull bracket 53 having a horizontally elongated first elongated hole 52 at the lower end is fixed to the lower end of the push-pull bracket 53, and inside the first elongated hole 52, a vertically intermediate portion is fixed. A horizontal shaft 5 is provided on a support bracket 55 fixed to the lower end of the matching frame 9a with screws 54, 54.
6, the upper pin 58 provided at the upper end of the bell crank 57 is loosely connected to the bell crank 57.
A lower pin 59 provided at the lower end of the horizontally movable member 36 is loosely engaged with a second elongated hole 62 which is elongated in the vertical direction and formed at the end of a connecting bracket 61 fixed to the end of the horizontally moving member 36 by screws 60, 60. ing.

When the transmission device is configured as described above, when the lever of the crescent metal fitting is rotated in the locking direction to lower the elevating rod 22b, the bell crank 5
7 rotates in the counterclockwise direction in FIG. 5 about the horizontal axis 56, pushes the horizontal moving member 36 in the direction of arrow a in FIG. Pull 7a towards the indoor side.

Note that the horizontally moving member 36 is provided over almost the entire length of the lower stile 7a (it is obvious that the upper stile 6a can be configured in almost the same way by reversing the top and bottom), and the horizontally moving member 36 It is also possible to provide a bracket 31 with swing arms 33 pivotally supported at a plurality of locations. In this case, if the brackets 31 are provided near both ends of the upper and lower frames 6a and 7a, it is not necessarily necessary to independently provide a mechanism for drawing the joining frames 9a and vertical frames 8a toward the indoor side. .

Further, a transmission device for converting the horizontal movement of the horizontal movement member 36 into vertical movement of the lifting rod is also provided between the lower stile 7a (or upper stile 6a) and the vertical stile 8a (Fig. 6), and the horizontal movement is It may also be configured such that a lifting rod is moved up and down inside the vertical stile 8a in conjunction with the movement of the member 36, and the movement of the lifting rod draws the vertical stile 8a toward the indoor side.

Further, in the above-described embodiment, the case of the indoor side sliding door shoji 5a of the sliding door was described, but the case of the outdoor side sliding door shoji 5b can be similarly configured. in this case,
Rather than operating the pulling mechanism of each sliding door shoji 5a, 5b independently, the sliding door shoji 5a, 5b is designed so that the pulling mechanism of both sliding door shoji 5a, 5b is interlocked by operating a single crescent metal fitting. It would be convenient if an interlocking mechanism is provided in the parts of the connecting frames 5b that face each other when the sliding doors are closed.

c. Effects of the invention Since the sliding door shoji pulling device of the present invention is constructed and operates as described above, it is possible to reliably pull a wide sliding door shoji, and the airtightness during locking is improved.
