Description

[Detailed description of the invention] (Industrial application field) The sliding door shoji pulling device according to this invention moves the sliding door shoji, which is generally used to open and close the window opening of a house, to the closed state and locks it. By pulling the sliding door shoji towards the indoor side in conjunction with the lock operation,
It presses the packing between the frame that surrounds the sliding door shoji and the sash frame in which the sliding door shoji is built, to maintain good airtightness between indoors and outdoors, and is applicable to large full-width sliding doors. It is valid.

(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 5 are widely used.

This sliding door has two inner and outer sliding door shoji 5a, 5b inside a sash frame 4 which is made up of a rectangular assembly of an upper frame 1, a lower frame 2, and left and right vertical frames 3, 3. 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 stiles 7a, 7b, vertical stiles 8a, 8b that face the vertical frames 3, 3 when the sliding door is closed;
It is constructed by assembling a rectangular pair of matching frames 9a, 9b which are parallel to the vertical frames 8a, 8b and facing each other when the sliding door is closed, and supporting glass on the inner circumferential side of each frame.

Among the matching frames 9a and 9b that constitute each sliding door shoji 5a and 5b, a crescent fitting 10 as shown in FIGS. 6 to 8 is attached to the matching frame 9a of the indoor sliding door 5a, and In the connecting frame 9b, a receiving bracket 11 as shown in FIG. ~ the state shown in Fig. 8), the vertical wall 17 formed at the base end of the lever 12 enters the inside of the receiving bracket 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. Calling frames 9a, 9b
By maintaining airtightness between sliding doors, soundproofing is done inside and outside the sliding doors.

In order to achieve this purpose, packing for airtightness is installed on 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 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. Vertical frames 8a, 8 are provided with packings 14, 14 over the entire length, and face the vertical frames 3, 3 when the sliding door is closed.
On the outer peripheral surface of b, the intermediate protrusion 13 (in the case of the outdoor 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) is provided.
In this case, the pulling blocks 16, 16 that abut each other are fixed.

Each protrusion 13, 1 of each pulling block 16, 16
The portion that abuts with the frame 5 forms an inclined surface toward the outdoor side as it approaches the outer circumferential surface of the vertical frames 8a, 8b. 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, 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, due to the engagement of the crescent metal fitting 10 and the receiving metal fitting 11, the outdoor sliding door shoji 5b, whose combined frame 9b is inseparably connected to the combined frame 9a of the indoor sliding door shoji 5a, is moved indoors. Packing 1 is moved inward in parallel and attached to the indoor side surfaces of both the upper and lower frames 6b, 7b of this outdoor sliding door shoji 5b.
9 and 19 are pressed against packings 18 and 18 attached to both the upper and lower frames 1 and 2.

Furthermore, the vertical wall 17 of the crescent fitting 10 is formed to have a radius that gradually becomes smaller in order to draw the outdoor matching stile 9b toward the indoor matching stile 9a when the lock is locked.
Due to the locking operation accompanying the rotation of 2, the distance between the outdoor side surface of the matching stile 9a of the indoor sliding door shoji 5a and the indoor side surface of the matching stile 9b of the outdoor sliding door shoji 5b becomes narrower. Packings 20, 20 attached to the indoor side surface of the interlocking stile 9b are pressed against the outdoor side surface of the interlocking stile 9a.

In addition, as the lever 12 of the crescent fitting 10 rotates, the matching frame 9a of the indoor sliding door shoji 5a
The pulling device that moves the building parallel to the indoor side is also shown on pages 338 and 358 of the above-mentioned "Building Comprehensive Catalog 1980 Edition".
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 constructed, for example, as shown in FIGS. 11 to 13, but the crescent fitting 10 used in this pulling device has a structure that is attached to the crescent fitting 10 as shown in FIG. Up and down rising and falling 2
Book pins 21a and 21b are provided, and this pin 2
Lifting rods 22a, 2 with one end connected to 1a, 21b
2b (FIGS. 11 to 13) drives 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 27 which is long in the front and back direction in FIG.
a, 27b, and each elevating plate 26a,
The pins 24a and 24b are installed at the other end of the pin 26b, respectively.

Since the crescent fitting 10 is configured in this way,
When the rotating body 23 rotates in conjunction 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 ends of the respective elevating plates 26a and 26b are located at the chain line position in FIG. 7 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.

Therefore, when the lever 12 of the crescent fitting 10 is moved from the unlocked position to the locked position, the 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 21b
The lifting rod 22b whose upper end is connected to the connecting rod 9
The inside of a 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 28a fixed to the upper end of the upper lifting rod 22a
The outdoor surface of the upper end forms an inclined surface that faces 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 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.

As a result, as the lever 12 rotates in the locking direction, the upper pulling block 28a is raised,
When the lower pulling block 28b is lowered, both the above-mentioned inclined surfaces and the upper and lower guide rails 29, 3
Due to the collision with the indoor side edge of 0, the connecting stile 9a
Both the upper and lower ends of are drawn towards the indoor side.

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

That is, to explain the sliding door shoji 5a on the indoor side as an example, the vertical stile 8a has pulling blocks 16 provided at multiple locations above and below the outer peripheral surface, and the connecting stile 9a abuts both the upper and lower guide rails 29, 30. The upper and lower frames 6a and 7a, both ends of which are connected and supported by the vertical frame 8a and the connecting frame 9a, are pulled toward the indoor side by the pulling blocks 28a and 28b, respectively.
is only drawn towards the indoor side following the vertical stile 8a and the matching stile 9a, and both the upper and lower stile 6a,
The middle portion of 7a is pressed toward the upper frame 1 or the lower frame 2 of the sash frame 4 based on its rigidity.

The width of the sliding door shoji 5a is small, and both the upper and lower frames 6
If the sliding door shoji 5a is wide and the rigidity of both the upper and lower frames 6a and 7a is small, there is little problem if the sliding door shoji 5a is thick and has sufficient rigidity. The pressing force of the packings 18 and 19 (FIG. 10) is insufficient at the intermediate portion of the sliding door shoji 5a and the sash frame 4, resulting in incomplete airtightness between the sliding door shoji 5a and the sash frame 4.

The pulling device for 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, so as to pull both the upper and lower stile toward the indoor side. As a result, the pressing force of the packing at the intermediate portion of both the upper and lower frames is sufficiently maintained, thereby eliminating the above-mentioned disadvantages.

(Means for solving the problem) The sliding door shoji pulling device of the present invention includes a horizontally movable rod 33 that is movable in the length direction inside the upper stile 6a or the lower stile 7a, and this horizontally movable rod 33. A moving member 31 that is driven based on the movement of the rod 33 and an upper frame 1
The upper guide rail 29 on the lower surface or the lower guide rail 30 on the upper surface of the lower frame 2 has an inclined surface 37 provided on the indoor side surface that becomes farther away from the indoor side toward the end, and a slanted surface 37 provided on the inner side of the stile 9a so as to be able to rise and fall freely. A lifting rod 22b that is raised and lowered in conjunction with the movement of the locking crescent 10, a push-pull bracket 41 whose base end is fixed to the end of the lifting rod 22b, and a tip end of the push-pull bracket 41. a horizontally long elongated hole 43 formed in the elongated hole 43; an intermediate shaft 46 loosely fitted inside the elongated hole 43; first and second arms 44 rotatably connected to each other by the intermediate shaft 46;
45, a support bracket 48 which is fixed to the end of the joining frame 9a and pivotally supports the end opposite to the intermediate shaft 46 of the first arm 44, and a second arm 45 which is fixed to the end of the horizontal movement bar 33. The movable member 31 and the inclined surface 37 can be engaged with each other as the movable member 31 moves horizontally based on the operation of the crescent 10. It is said that

(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 10 is rotated to the locked state, the sliding door shoji puller device of the present invention is An elevating rod 22b moves up and down inside the elevating rod 9a, and a push-pull bracket 41 fixed to the end of the elevating rod 22b moves up and down.

As a result, the toggle device constituted by the first and second arms 44, 45 is extended from its previously bent state.

As a result, the second arm 45 pushes the horizontally moving rod 33, which drives the moving member 31 to collide with the inclined surface 37, thereby moving the upper stile 6a or the lower stile 7a.
pull it indoors.

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

1 to 4 show embodiments of the present invention. In the case of this embodiment, a roller-shaped moving member 31 that rotates around a vertical shaft 36, which moves in parallel with the horizontal movement of the horizontal moving rod 33, and an indoor side surface of the lower guide rail 30 on the upper surface of the lower frame 2, The structure is such that the lower stile 7a is drawn toward the indoor side (the right side in FIG. 1, the front side in FIG. 2, and the upper side in FIG. 3) by colliding with an inclined surface 37 formed on a fixed wedge plate 32.

That is, it fits inside the lower stile 7a, and this lower stile 7a
A bracket 35 is attached to the lower surface of the horizontally moving rod 33, which can only move freely in the horizontal direction along a, and screws 34, 3
It is fixed by 4. The roller-shaped moving member 31 is rotatably supported on a vertical shaft 36 hanging from the lower surface of the bracket 35.

On the other hand, on the indoor side surface of the lower guide rail 30 on the upper surface of the lower frame 2, a wedge plate 32 is provided at the part facing the moving member 31 when the sliding door shoji 5a is in the closed state.
is fixed by engagement with a through hole 39 formed in the lower guide rail 30 and tightening of a screw 40. At one end of this wedge plate 32, the moving member 31
The portion that abuts against is an inclined surface 37. The direction of inclination of this inclined surface 37 is such that the closer it is to the center of the wedge plate 32, the more it faces toward the indoor side.

In the case of the pulling device for a sliding door shoji of the present invention using such a moving member 31, when the crescent fitting 10 of the connecting frame 9a shown in FIGS. 5 to 9 is in the unlocked state, the moving member 31 31 and wedge plate 3
2 are separated from each other as shown in FIGS. 2 and 3, and the lower stile 7a is not drawn toward the indoor side, but the crescent fitting 10 is rotated to the locked state,
When the horizontal moving rod 33 is pushed to the right in FIGS. 2 and 3 via the lifting rod 22b and the transmission device, the moving member 31
The vertical shaft 3 collides with the inclined surface 37 of the wedge plate 32, and as a reaction, supports the moving member 31.
6 is pushed toward the indoor side, and the lower stile 7a 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 up and down inside the matching stile 9a, and the end of the horizontally moving rod 33 moves horizontally inside the lower stile 7a. A transmission device for connecting the vertical movement of the lifting rod 22b by 90 degrees and transmitting the vertical movement to the horizontal movement rod 33 is constructed as shown in FIG.

Crescent metal fittings 10 (5th to 8th) when locking
The upper end base of a push-pull bracket 41 is fixed by screws 42, 42 to the lower end of the elevating rod 22b which moves up and down inside the matching frame 9a in conjunction with the rotation shown in FIG.

A long hole 43 which is elongated in the horizontal direction is formed at the lower end of the push-pull bracket 41 . An intermediate shaft 46 that rotatably connects the first and second arms 44 and 45 to each other is fitted into the elongated hole 43.

The first and second arms 44, 45 connected by this intermediate shaft 46 constitute a toggle device, and the end of the first arm 44 is connected to the lower end of the connecting frame 9a by a screw 47. It is pivotally supported by a shaft 49 on a support bracket 48 fixed by 47.

The end of the second arm 45 is pivotally supported by a shaft 50 on a connecting bracket 51, and this connecting bracket 51 is connected to the lower frame 7a by screws 52, 52.
It is engaged and fixed to the end of a horizontally moving rod 33 provided in FIG. 1.

Therefore, when the elevating rod 22b descends as the crescent fitting 10 rotates to the locked state, the intermediate shaft 46 is pushed downward via the push/pull bracket 41, causing it to bend as shown in FIG. The first and second arms 44 and 45, which had been in a bent state, extend straight, and the horizontal moving rod 33 is pushed in the direction of arrow a in FIG. 4 through the connecting bracket 51, and the moving member 31 Slanted surface 37 of wedge plate 32 (Figures 2 and 3)
and collide, and the lower stile 7a is drawn toward the indoor side.

The inclined surface 37 can be provided on the indoor side surface of the lower guide rail 30 by fixing the wedge plate 32 as described above, or by bending a part of the lower guide rail 30 using a press.

It should be noted that the horizontal movement rod 33 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 this horizontal movement It is also possible to provide moving members 31 at a plurality of locations on the rod 33, and to provide wedge plates 32 at portions of the indoor side surface of the lower guide rail 30 that correspond to the respective moving members 31. In this case, if the moving member 31 is provided near both ends of the upper and lower frames 6a and 7a, it is not necessarily necessary to independently provide a device for pulling the joining frame 9a and the vertical frame 8a toward the indoor side. It disappears.

In addition, the lower stile 7a (or the upper stile 6a) is a transmission device that converts the horizontal movement of the horizontal movement rod 33 into the elevation of the lifting rod.
and the vertical stile 8a (Fig. 9), and in conjunction with the movement of the horizontal moving rod 33, the vertical movement lever is moved up and down inside the vertical stile 8a, and the movement of the vertical stile 8a moves the vertical stile 8a.
It can also be constructed so that it is drawn towards 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,
Instead of operating the pulling devices of each sliding door shoji 5a, 5b independently, the sliding door shoji 5a, 5b are operated in conjunction with each other by operating a single crescent fitting. It is convenient if an interlocking device is provided in the parts of the connecting frames 9a and 9b of 5b that face each other when the sliding doors are closed.

(Effects of the Invention) The sliding door shoji pulling device of the present invention is configured and operates as described above, so that a wide sliding door shoji can be reliably pulled in, improving airtightness during locking.
