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, the inside and outside of the sliding door is soundproofed. 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, there is 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 protrusion 13, 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

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, whose connecting frame 9b is inseparably connected to the connecting frame 9a of the indoor sliding door shoji 5a, is moved to the indoor side. , and press the packing 19, 19 attached to the indoor side surfaces of the upper and lower frames 6b, 7b of this outdoor sliding door shoji 5b against the packing 18, 18 attached to the upper and lower frames 1, 2. There is. 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 joining stile 9a of the indoor sliding door shoji 5a and the indoor side surface of the joining stile 9b of the outdoor sliding door shoji becomes narrower.
~ As shown in Figure 10, the packing 20, 20 attached to the indoor side of the connecting frame 9b is attached to the connecting frame 9b.
It is pressed against the outdoor side of a.

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, 22b (FIGS. 12 to 14), one end of which is connected to the pins 21a, 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, the 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 elevator 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 same 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 pull block 28a fixed to the upper end of the pull block 28a has an inclined surface that slopes upward toward the indoor side, and the lower end of the pull 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 locked on 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 the upper and lower frames 6a, 7a, and the sliding door shoji 5a and The airtightness between the sash frame 4 and the sash frame 4 becomes 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. Structure of the invention (Means for solving the problem) In the pulling device for sliding door shoji of the invention, a bracket is fixed to the middle part of the upper stile or the lower stile, and the end part is fixed to this bracket. A wedge piece having an inclined surface inclined in a direction away from the indoor side surface of 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 is supported so as to be able to rise and fall.

A bell crank is pivotally supported on the bracket, and a pin provided at one end of the bell crank is loosely engaged with a horizontally elongated hole formed in the middle of the wedge piece, and a pin provided at one end of the bell crank is fitted into a horizontally long hole formed in the middle of the wedge piece. is connected to a fixed movable bracket to a horizontal movable member that is provided to be movable along the upper or lower stile.

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

(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, A lifting rod moves vertically inside the combining member, and a horizontally moving member connected to an 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 bell crank connected to the moving bracket fixed to the end of the horizontally moving member rotates, and the pin at one end of the bellcrank pushes the wedge piece in the vertical direction.
This wedge piece is raised and lowered toward the upper or lower guide rail.

As the wedge piece moves up and down, when the tip of this wedge piece enters the gap between the upper or lower stile and the indoor side surface of the guide rail, the gap is pushed wider and the upper or lower stile is pushed out. The lower stile is pulled toward the interior.

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

At the middle part of the lower stile 7a is a box-shaped bracket 31 which is formed by bending a metal plate and is open at the bottom.
Outward flanges 32, 32 provided at the lower end opening of this bracket 31 are fixed by screws 33, 33.

One longitudinal end of the lower stile 7a of this bracket 31 has an inclined surface 35 at its lower end that is inclined in a direction away from the indoor side surface of the lower guide rail 30 on the upper surface of the lower frame as it goes downward. A wedge piece 34 whose thickness decreases downwardly is supported so as to be movable up and down.

A compression spring 38 is provided between the lower surface of the wedge piece 34 and the protrusion 36 formed to protrude laterally at the middle part, and the upper surface of the bottom plate 37 that closes a part of the lower opening of the bracket 31. It gives elasticity in the upward direction.

A horizontal shaft 3 provided at the middle lower part of the bracket 31
9 pivotally supports an intermediate portion of a bell crank 40, and a pin 41 provided at one end of the bell crank 40 is connected to a protrusion 36 of the intermediate portion of the wedge piece 34.
It is made to fit loosely into a horizontally long elongated hole 42 formed in .

Inside the vertically long elongated hole 53 formed at the other end of the bell crank 40, a hole 53 is provided at one end of the link 43 and is fitted into a dogleg-shaped engagement groove 54 formed on the side wall of the bracket 31. The pin 55 is loosely engaged, and the other end of the link 43 is pivotally supported on the upper end of the movable bracket 44.

A guide pin 46 fixed to the bracket 31 and the horizontal shaft 39 are loosely engaged with two horizontally long elongated holes 45, 45 formed in the movable bracket 44, so that the movable bracket 44 can be attached to the bracket. 31 so that it can only move horizontally.

A circular hole 47 drilled in the bottom of the movable bracket 44 has a push-pull bracket 50 fixed to the horizontal movable member 48 with screws 49, 49, which can only move in the horizontal direction along the lower stile. An upright pin 51 embedded in the upper surface is inserted so that the movable bracket 44 moves in the horizontal direction based on the horizontal movement of the horizontally moving member 48.

Furthermore, a lifting rod 22b is provided inside the lower half of the connecting frame 9a of the sliding door shoji 5a so as to be movable up and down, and is linked to the movement of the locking crescent (see Fig. 12).
The end of the horizontally moving member 48 is connected to the end of the horizontally moving member 48 by a transmitting device that converts the direction of movement at right angles.

In the sliding door shoji pulling device of the present invention constructed as described above, when the sliding door shoji 5a is in the closed state and the crescent is rotated to the locked state,
The lifting rod 22b is lowered inside the connecting frame 9a provided with a crescent, and the horizontal moving member 48 connected to the lower end of the lifting rod 22b via a transmission device moves along the lower frame 7a as shown in FIGS. Move horizontally to the right.

When the horizontally moving member 48 moves in this way, the push/pull bracket fixed to the end of the horizontally moving member 48 by screws 49, 49 moves to the right in FIGS. The provided moving bracket 44 is also moved to the right.

As the movable bracket 44 moves, the bell crank 40 connected to the movable bracket 44 via the link 43 rotates clockwise in FIG.
A pin 41 provided at one end of is lowered.

Since the pin 41 is loosely engaged with a long hole 42 formed in the middle of the wedge piece 34, as the pin 41 descends, the wedge piece 34 is pushed downward, and the lower stile 7a
It descends straight toward the lower guide rail 30 along guides 80 and 81 fixed to the lower guide rail 30.

Wedge piece 34 accompanying rotation of bell crank 40
As the wedge piece 34 is lowered, the lower end of the wedge piece 34 enters the gap 52 between the lower stile 7a and the indoor side surface of the lower guide rail 30 on the upper surface of the lower frame, and expands the gap 52. For this reason, the lower stile 7a is drawn toward the indoor side (the right side in FIG. 3).

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. The transmission device for connecting the vertical movement of the lifting rod by 90 degrees and transmitting the vertical movement to the horizontally moving member may have various shapes and structures. For example, a flexible transmission member such as a leaf spring is housed in an L-shaped hollow housing, and the lower end of a lifting rod is attached to one end of the flexible transmission member exposed from the housing. A transmitter can also be constructed by connecting one end of a horizontally moving member to each end.

As for the structure of the transmission section, 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 56 is fixed to the lower end (see FIG. 14) by screws 57, 57. A horizontally long elongated hole 58 is formed at the lower end of the push-pull bracket 56.
This elongated hole 58 has first and second arms 59, 60.
An intermediate shaft 61 rotatably connects the two to each other. The first, connected by this intermediate shaft 61,
The second arms 59 and 60 constitute a toggle mechanism, and the end of the first arm 59 is attached to a shaft 64 on a support bracket 63 fixed to the lower end of the joining frame 9a with screws 62 and 62. It is supported by
The end of the second arm 60 is pivotally supported by a shaft 65 on a connecting bracket 66, and this connecting bracket 66 is connected to a horizontally moving member provided on the lower stile 7a (FIGS. 6 and 11) by screws 67, 67. It is connected and fixed to the end of 48. Therefore, when the lifting rod 22b descends as the crescent fitting rotates to the locked state, the intermediate shaft 61 is pushed downward via the push/pull bracket 56, causing the intermediate shaft 61 to bend as shown in FIG. First and second arms in condition 5
9 and 60 extend linearly, and the horizontally moving member 48 is pushed in the direction of arrow a in FIG.
Accordingly, the wedge piece 34 descends, and the lower stile is drawn toward 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. At the lower end of the push-pull bracket 69, which has a horizontally elongated first hole 68, the upper end base of the push-pull bracket 69 is screwed into
9, and inside the first elongated hole 68, the vertically intermediate portion is pivoted on a horizontal shaft 72 provided on a support bracket 71 fixed to the lower end of the joining frame 9a with screws 70, 70. Supported bell crank 7
The upper pin 74 provided at the upper end of the bell crank 73 is loosely engaged with the lower pin 74 provided at the lower end of the bell crank 73.
5 has a screw 76 at the end of the horizontally moving member 48;
It is loosely engaged with a second elongated hole 78 which is elongated in the vertical direction and is formed at the end of a connecting bracket 77 fixed by a connecting bracket 76 .

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 7
3 rotates counterclockwise in FIG. 5 about the horizontal shaft 72, pushes the horizontal moving member 48 in the direction of arrow a in FIG. 5, lowers the wedge piece 34, and lowers the lower stile 7.
Pull a towards the indoor side.

Note that the horizontally moving member 48 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 48 A push-pull bracket 5 for raising and lowering the wedge pieces 34 at multiple locations.
It can also be fixed at 0. In this case,
If the wedge pieces 34 are provided near both ends of the upper and lower frames 6a, 7a, it is not necessarily necessary to independently provide a mechanism for drawing the joining frame 9a and the vertical frame 8a toward the indoor side.

Further, a transmission device for converting the horizontal movement of the horizontal movement member 48 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 is also possible to move a lifting rod up and down inside the vertical stile 8a in conjunction with the movement of the member 48, and to draw the vertical stile 8a toward the indoor side by the movement of the lifting rod.

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.
