Description

[Detailed explanation of the invention] a. Purpose of the invention (industrial application field) The interlocking device of the lifting rod for the sliding door shoji pulling device of the sliding door according to this invention is used for opening and closing window openings in general houses. When a sliding door is closed, by pulling the sliding door shoji toward the indoor side, the packing is pressed between the stile that surrounds the sliding door shoji and the sash frame in which the sliding door shoji is built, creating a good airtightness between indoors and outdoors. In order to keep the sliding door shoji at the same height, the sliding door shoji (inner and outer sliding door shoji) are linked with pulling devices, and is effective when applied to large-height sweeping windows.

(Prior art) In order to open and close openings in general houses, etc., for example, the "Comprehensive Building Catalog 1980 Edition" published by the applicant company,
As described in many publications such as the ``Comprehensive Residential Catalog 1982 Edition'', sliding doors like the one shown in Figure 9 are widely used.

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 its length.

The above-mentioned double sliding door shoji 5a, 5b each have an upper stile 6.
a, 6b, lower frames 7a, 7b, vertical frames 8a, 8b that face the vertical frames 3, 3 when the sliding door is closed,
It is constructed by assembling frames 9a, 9b parallel to the vertical frames 8a, 8b and facing each other when the sliding door is closed into a rectangular shape, and supporting glass on the inner circumferential side of each frame.

A matching frame 9 that constitutes each sliding door shoji 5a, 5b
Among a and 9b, the joining frame 9 of the indoor sliding door shoji 5a
12-14, a crescent fitting 10 as shown in FIGS.
In the portions facing the crescent metal fittings 10, receiving metal fittings 11 as shown in FIG. 14 are respectively provided. When closing the sliding door, by rotating the lever 12 of the crescent fitting 10 to the closed state (the state shown in Figs. 12 to 14), the vertical wall 17 formed at the base end of the lever 12 is moved inside the receiving fitting 11. and lock the sliding doors.

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, when the sliding door is closed, each stile that faces each other is fitted with packing to maintain airtightness on the surface of each frame, 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 to the direction, the packing is pressed between the stile and the frame.

For example, as shown in FIG. Attach packing 14, 14 along 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.

A part of each pulling block 16, 16 that collides with each protrusion 13, 15 is a part of the vertical frame 8a, 8b.
It forms an inclined surface toward the outdoor side as it approaches the outer peripheral surface. Therefore, when each sliding door shoji 5a, 5b is moved to the closed state, each vertical frame 8a, 8b moves in parallel toward the indoor side, and the indoor side surface of this vertical frame 8a, 8b is attached to the packing 14, 14. The airtightness between each vertical stile 8a, 8b and the vertical frames 3, 3 is maintained by pressing the vertical frame 8a, 8b toward the vertical frame 3, 3.

In addition, both the upper and lower frames 1 and 2 of the sash frame 4 and the upper and lower frames 6a, 6b, 7a, 7b of each sliding door shoji 5a, 5b
There is also packing 1 as shown in Figure 11.
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, 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 into the room by the engagement of the crescent metal fitting 10 and the receiving metal fitting 11. Both the upper and lower frames 6b of this outdoor sliding door shoji 5b are moved inward in parallel,
Packing 19, 19 attached to the indoor side of 7b
Packing 18, 1 attached to both upper and lower frames 1, 2
I try to press it to 8.

Furthermore, the vertical wall 17 of the crescent fitting 10 connects the outdoor side connecting stile 9b to the indoor side connecting stile 9 when the door is locked.
Since it is formed so that the radius gradually becomes smaller in order to draw it toward the direction a, the indoor sliding door 5 can be closed by the locking operation accompanying the rotation of the lever 12.
The distance between the outdoor side of the connecting stile 9a of a and the indoor side of the connecting stile 9b of the outdoor sliding door shoji 5b becomes narrower, and the packing 20, 20 attached to the indoor side of the connecting stile 9b is aligned. It is pressed against the outdoor side of the stile 9a.

In addition, the pulling device that moves the joining stile 9a of the indoor sliding door shoji 5a parallel to the indoor side as the lever 12 of the crescent fitting 10 is rotated is also described on page 338 of the above-mentioned "Building General Catalog 1980 Edition". No. 358
It has been widely known for a long time, as described on page 479 of the ``Comprehensive Residential Catalog 1982 Edition''.

This pulling device is configured as shown in FIGS. 15 to 17, for example, and the crescent metal fitting 10 used in this pulling device has a crescent fitting 10 that is attached to the crescent fitting 10 as shown in FIG. A lifting rod 22 is provided with two upper and lower pins 21a and 21b that move up and down, and one end of which is connected to these pins 21a and 21b.
a, 22b (FIGS. 15-17) actuate the pulling device.

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 is a long hole 2 which is long in the front and back direction in FIG.
7a and 27b, each elevating plate 26
The pins 24a, 24b are attached to the other ends of a, 26b.
are planted respectively.

Since the crescent fitting 10 is configured in this way,
When the rotary body 23 rotates with the rotation of the lever 12, the two upper and lower elevating plates 26a, 26b moves up and down.

Therefore, when the lever 12 is rotated to the unlocked state, the pins 21a and 21b provided at the end of each lifting plate 26a and 26b are in the chain line position in FIG. 13 to lock the lever 12. By rotating it to the position shown in the figure, it moves to the position shown by the solid line in the figure.

As a result, when the lever 12 of the crescent metal fitting 10 is moved from the unlocked position to the locked position, the lift 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, whose upper end is connected, is pushed down inside the joining frame 9a.

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 2 fixed to the upper end of the upper lifting rod 22a
The outdoor surface of the upper end of the drawing block 28b, which is fixed to the lower end of the lower lifting rod 22b, is inclined toward the indoor side as it goes downward. Each inclined surface abuts the lower indoor side edge of the upper guide rail 29 formed on the lower surface of the upper frame 1 or the upper indoor side edge of the lower guide rail 30 formed on the upper surface of the lower frame 2. I am free to do so.

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 above-mentioned inclined surfaces and the upper, lower, and both guide rails 29, 3
Due to the collision with the indoor side edge of 0, both upper and lower ends of the connecting stile 9a are drawn toward the indoor side.

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

That is, the combination frame 9 of both the inside and outside sliding door shoji 5a, 5b
Among a and 9b, the joining frame 9 of the indoor sliding door shoji 5a
A is drawn toward the indoor side at both the upper and lower ends, but the joining frame 9b of the outdoor sliding door shoji 5b is connected to the crescent metal fitting 10 and the receiving metal fitting 11 provided at the intermediate part of both the inside and outside sliding door sills 9a and 9b. It is only through this engagement that the indoor sliding door shoji 5a is drawn toward the joining frame 9a.

The sliding door is installed in an opening with a small height like a waist window, and the sliding frame 9b is thick,
If the sliding door has sufficient rigidity, there is little problem, but if the sliding door is installed in a large opening such as a bay window, or if the connecting frame 9b is thin and the rigidity is small. In some cases, this connecting frame 9b is curved so that 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 in the middle part of the connecting frames 9a and 9b but also at both the upper and lower ends, such inconvenience will not occur, but the locking and unlocking operations of the sliding door will become troublesome. This is not desirable.

The interlocking device of the lifting rod for the pulling device of the sliding door shoji in the sliding door of the present invention is configured to move the connecting stile on the side where the crescent metal fitting is not provided in parallel in one movement, thereby achieving the above-mentioned effect. This is to eliminate the inconvenience.

b. Composition of the invention (means for solving the problem) The interlocking device of the lifting rod for the pulling device of the sliding door shoji in the sliding door of the invention has an upper stile, a lower stile, a vertical stile, and a connecting stile, respectively. A sliding sliding door in which an outdoor sliding door shoji and an indoor sliding door shoji are enclosed on all four sides and are built into a sash frame consisting of an upper frame, a lower frame, and vertical frames on the left and right, each movable in the longitudinal direction of the upper and lower frames. With the movement of the crescent metal fittings built into the door and installed in the connecting frame of the indoor sliding door shoji, the first lifting rod installed in this connecting frame is raised and lowered, and the indoor sliding door shoji and the sash are moved up and down. At the same time as operating the pulling device provided between the outdoor sliding door shoji and the sash frame, a second elevating rod provided within the joining frame of the outdoor sliding door shoji is raised and lowered, and the second elevating rod provided between the outdoor sliding door shoji and the sash frame is This actuates the pulling device.

The interlocking device of the lifting rod for the pulling device of the sliding door shoji in the sliding door of the present invention is provided within the joining frame of the indoor sliding door shoji, and is adapted to the movement of the crescent fitting for locking the sliding door shoji. A first lifting rod that moves up and down in conjunction with each other to operate a pulling device provided between the indoor sliding door shoji and the sash frame, and a drive block fixed in the middle of the first lifting rod. , is formed on the outdoor side of the joining frame of the indoor sliding door shoji, and is formed at the part facing the joining frame of the outdoor sliding door shoji when the sliding door is closed, and is long in the vertical direction, and lifts and lowers a part of the drive block. A first elongated hole that can be freely moved together and a pulling device provided in the joining frame of the outdoor sliding door shoji, which is provided between the outdoor sliding door shoji and the sash frame as the sliding door shoji moves up and down, is actuated. A second lifting rod, a driven block fixed in the middle of the second lifting rod, and an indoor side surface of the connecting frame of the outdoor sliding door shoji, which is connected to the first elongated hole when the sliding door is closed. It is comprised of a second long hole formed in the opposing portion, which is elongated in the vertical direction, and allows a part of the driven block to move freely up and down.

The drive block has a washboard-like unevenness extending in the vertical direction on the outdoor side surface, a drive side main body fixed in the middle of the first elevator rod, and an unevenness on the indoor side surface that engages with the unevenness. and a drive-side plate piece that is connected to the drive-side main body with screws so as to be vertically adjustable. In addition, the above-mentioned driven block is
The driven side body has a washboard-like unevenness extending in the vertical direction on the indoor side surface and is fixed in the middle of the second lifting rod, and has an unevenness on the outdoor side surface that engages with the unevenness, and the above-mentioned It is composed of a driven side plate piece that is coupled to the driven side main body so that its vertical position can be freely adjusted.

A part of the drive side plate piece protrudes from the outdoor side surface of the joining stile of the indoor sliding door shoji through the first long hole, and a part of the driven side plate piece protrudes from the second long hole. Through the hole, the part of the stile of the outdoor sliding door shoji that protrudes from the indoor side surface,
By making the recesses and projections freely engageable when the sliding door shoji is closed, the second elevating rod can be raised and lowered in conjunction with the raising and lowering of the first elevating rod when the sliding door shoji is closed.

(Function) In the interlocking device of the lifting rod for the pulling device of the sliding door shoji in the sliding door of the present invention constructed as described above, by operating the crescent fitting, the pulling stile of the indoor sliding door shoji can be moved. When the first lifting rod on the inside of the shaft is raised and lowered, a drive block fixed to this first lifting rod is raised and lowered, and a driven block having a driven side plate piece that engages a driving side plate piece concave and convexly with a driving side plate piece constituting this drive block moves up and down. At the same time, the second lifting rod to which the driven block is fixed is raised and lowered within the connecting frame of the outdoor sliding door shoji. Then, a pulling device provided between the outdoor sliding door shoji and the sash frame is activated.

As a result, not only the indoor sliding door shoji provided with the crescent, but also the outdoor sliding door shoji not provided with the crescent fittings are drawn toward the indoor side.

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

1 and 2 show an embodiment of the present invention, where FIG. 1 is a view corresponding to the AA cross section in FIG. 9, and FIG. 2 is a view seen from the right side of FIG. 1. There is a crescent fitting 1 in the matching frame 9a of the indoor sliding door shoji 5a.
A first elevating rod 31 that moves up and down in conjunction with the rotation of the lever 12 (see FIGS. 12 to 14) is fitted so that it can only move up and down.

In the middle of this first lifting rod 31, there is a drive block 32 made of a slippery hard material such as nylon.
A main body 34 is fixed by screws 33.
A first elongated hole 35 that is long in the vertical direction is formed in the outdoor side surface of the joining stile 9a at the portion where this drive block 32 faces.
A drive side plate piece 37 having a U-shaped vertical wall 36 formed on the outdoor side surface is movably engaged with the drive side plate 5 in the drive unit 5 so as to be movable up and down.

This drive side plate piece 37 and the drive side main body 34 are connected and fixed by screws 38, 38 to constitute the drive block 32, but both members 37, 34
The mutually abutting surfaces of the screws 38 and 38 are washboard-like uneven surfaces extending in the vertical direction, so that the relative positions of the two members 37 and 34 in the vertical direction can be adjusted by one pitch of the unevenness. 38, the drive-side plate piece 37 is prevented from shifting relative to the drive-side main body 34.

On the other hand, inside the connecting frame 9b of the outdoor sliding door shoji 5b, there is a second lifting rod 39 for operating a pulling device that moves the end of the connecting frame 9b toward the indoor side. It is fitted freely. And, in the middle of this second lifting rod 39,
Like the drive block 32, the driven side main body 41 of the driven block 40 is made of nylon or the like.
It is fixed with screws 42.

On the indoor side surface of the joining stile 9b, in a portion facing the driven block 40 and the first elongated hole 35, there is a second elongated hole elongated in the vertical direction, similar to the first elongated hole 35. 43 is formed. A driven side plate piece 45 is fitted in the second elongated hole 43 so as to be movable up and down. A protrusion 44 that can freely enter into the vertical wall 36 is formed on the indoor side surface of the driven side plate piece 45, and the driven side plate piece 45 is coupled and fixed to the driven side main body 41 with screws 46, 46. This constitutes a driven block 40.

The driven side main body 4 that constitutes this driven block 40
1 and the driven side plate piece 45, similarly to the drive block 32 described above, is a washboard-like uneven surface extending in the vertical direction. While the unevenness can be adjusted by one pitch, when tightening the screws 46, 46,
The driven side plate piece 45 is prevented from shifting relative to the driven side main body 41.

The driving block 32 and the driven block 40 formed as described above are such that when the inner and outer sliding door shoji 5a, 5b are installed inside the sash frame 4 (FIG. 9), the protrusion 44 on the driven block 40 side The height positions of the drive-side plate piece 37 and the driven-side plate piece 45 are adjusted so that they enter into the vertical wall 36 on the drive block 32 side and engage with the protrusions and recesses.

Therefore, when the first elevating rod 31 moves up and down as the lever 12 of the crescent fitting 10 rotates, this movement remains almost unchanged and the drive block 3
2. Second lifting rod 39 via driven block 40
This is also transmitted to the vertical axis, so that both lifting rods 31 and 39 move up and down at the same time.

In this way, both the first and second lifting rods 31 and 39 that rise and fall at the same time actuate the pulling devices provided on the joining frames 9a and 9b of each sliding door shoji 5a and 5b as they rise and fall, respectively. Double-sided frames 9a, 9b
pull it indoors.

In addition to the drawing devices shown in FIGS. 15 to 17, the pulling devices that pull the connecting frames 9a and 9b toward the indoor side as the lifting bars 31 and 39 move up and down can be of various conventionally known structures. You can adopt things.

Furthermore, the concave-convex engagement between the drive block 32 and the driven block 40 is not limited to that shown in FIGS. 1 and 2. For example, as shown in FIG. 3, three standing walls 47, 47 are formed on one plate piece 37 (or 45), and two standing walls 47 are formed on the other plate piece 45 (or 37).
8 and 48 may be formed, and the compatible walls 47 and 48 may be engaged with each other.

Furthermore, as shown in FIG. 4, one plate piece 37 (or 45) is provided with a prismatic or cylindrical pin 49, and the other plate piece 45 (or 37) is provided with fifth to eighth pins. This pin 49 can also be engaged with a through hole 50 or a notch 51 having a shape as shown in the figure.
Of course, the structures shown in FIGS. 3 to 8 are also a type of concave-convex engagement according to the present invention.

c. Effects of the invention The interlocking device of the lifting rod for the pulling device of the sliding door shoji in a sliding door of the present invention is constructed and operates as described above, so when applied to a sliding door, for example, only the sliding door shoji on the indoor side can be used. In addition, the connecting frame of the outdoor sliding door shoji can be pulled strongly toward the indoor side, and airtightness can be sufficiently maintained at both the upper and lower ends of the connecting frame, and the locking operation is the same as before. It can be done through behavior.

Further, the driving side plate piece and the driven side plate piece which engage each other in uneven manner when the sliding door is closed are attached to the driving side main body and the driven side main body fixed in the middle of the first elevating rod and the second elevating rod, respectively. Since they are coupled so that their vertical positions can be freely adjusted, it is possible to reliably engage the driving side plate piece and the driven side plate piece with the unevenness while reducing play in the vertical direction of the uneven portion.

As a result of being able to reduce the play in this way, the difference between the lifting amount of the first lifting rod and the lifting amount of the second lifting rod can be reduced, so that the lifting amount of the first lifting rod is not increased unnecessarily. , the pulling device on the indoor sliding door shoji side can be operated reliably.
