Description

[Detailed description of the invention] a. Purpose of the invention (industrial application field) The power transmission device for a pulling device for a sliding door shoji according to this invention is a power transmission device for a pulling device for a sliding door shoji for opening and closing a window opening of a general house until the sliding door shoji is closed. When the sliding door shoji is moved and locked, the sliding door shoji is pulled toward the indoor side in conjunction with the locking operation, thereby pressing down on the gap between the frame that surrounds the sliding door shoji and the sash frame in which the sliding door shoji is built. However, it is used to drive the pulling device of the sliding door shoji, which maintains good airtightness inside and outside the room, and is effective when applied to a sliding door shoji with a large overall width.

(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 ``Residential General Catalog 1982 Edition'', sliding doors like the one shown in Figure 12 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, 9b that constitute each sliding door shoji 5a, 5b, a crescent fitting 10 as shown in FIGS. 13 to 15 is attached to the matching frame 9a of the indoor sliding door 5a, and A receiving bracket 11 as shown in FIG. 15 is provided in the part of the connecting frame 9b facing the crescent bracket 10, respectively, and when the sliding door is closed, the lever 12 of the crescent bracket 10 is in the closed state (the first 13 to 15), the vertical wall 17 formed at the base end of the lever 12 enters the inside of the receiving fitting 11, so that the sliding door can be locked.

The basic structure of the sliding door is as described above, but when closed, the space between each stile surrounding the four circumferences of each sliding door shoji 5a, 5b and each frame constituting the sash frame, and both 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. 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.

Each protrusion 13 of each pulling block 16, 16,
The portion that abuts with 15 forms an inclined surface toward the outdoor side as it approaches the outer peripheral 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, since the vertical wall 17 of the crescent fitting 10 is formed so that the radius gradually becomes smaller in order to draw the outdoor matching stile 9b toward the indoor matching stile 9a when locking, the lever 12 Due to the locking operation accompanying the rotation, 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, and the matching stile is closed. Packings 20, 20 attached to the indoor side surface of the frame 9b are pressed against the outdoor side surface of the 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 General Catalog 1980 Edition".
It has been widely known for a long time, as stated on page 479 of the ``Comprehensive Residential Catalog 1982 Edition''.

This pulling device is constructed as shown in FIGS. 18 to 20, for example, and the crescent 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 is connected to these pins 21a and 21b.
a, 22b (Figs. 18-20) drive the pulling device.

That is, the two pins 24a, 2 formed on the rotating body 23 interlocking with the lever 12 of the crescent fitting 10
Reference numeral 4b denotes a long hole 2 extending in the front and back directions 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. 14 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 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 21
The lifting rod 22b, whose upper end is connected to the upper end of the lifting rod 22b, is pushed down into the connecting 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 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 abuts the lower end indoor side edge of the upper guide rail 29 formed on the lower surface of the upper frame 1 or the upper end 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.

For this reason, as the lever 12 is rotated in the locking direction, the upper drawing block 28a is raised.
When the lower pulling block 28b is lowered,
Due to the collision between the two inclined surfaces and the indoor edges of the upper and lower guide rails 29, 30, 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 sliding door shoji pulling device constructed and operated as described above, the following disadvantages occur.

That is, taking the indoor sliding door shoji 5a as an example,
The vertical stile 8a is pulled toward the indoor side by pulling blocks 16 provided at multiple locations above and below the outer peripheral surface, and the matching stile 9a is pulled toward the indoor side by pulling blocks 28a and 28b that collide with both the upper and lower guide rails 29 and 30, respectively. Both upper and lower frames 6a and 7a are connected and supported at both ends by the vertical frame 8a and the matching frame 9a.
is simply drawn toward the indoor side by following the vertical stile 8a and the matching stile 9a, and both the upper and lower stile 6
The intermediate portions a and 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 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. 17) 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.

By incorporating the power transmission device for a pulling device of a sliding door shoji of the present invention into the pulling device of a sliding door shoji, it can be used not only for the vertical stile and the combined stile of the sliding door shoji, but also for the middle part between the upper and lower stile. By making it possible to freely draw both frames toward the indoor side, the pressing force of the packing at the intermediate portion of both the upper and lower frames can be maintained sufficiently, thereby solving the above-mentioned inconvenience.

b. Structure of the invention (means for solving the problem) The power transmission device for a pulling device for a sliding door shoji of the present invention is capable of moving the upper stile or the lower stile in the longitudinal direction. A horizontally moving rod that drives a pulling device that pulls the lower stile toward the indoor side, a lifting rod that is provided inside the stile so as to be able to rise and fall and is linked to the movement of a locking crescent, and the above-mentioned upper stile or lower stile. a pinion pivotally supported at the end of the vertical stile by a horizontal axis in the width direction of the vertical axis; a first rack-like plate fixed to the end of the lifting rod and meshing with the pinion; and a second rack-shaped plate fixed to the end of the moving rod and meshing with the pinion.

(Function) The power transmission device for a pulling device for a sliding door shoji of the present invention is constructed as described above, but when the sliding door shoji is in a closed state and the crescent is rotated to a locked state, A lifting rod moves up and down inside the stile and pushes against a first rack-shaped plate provided at the end of the lifting rod.

When the first rack-shaped plate is pushed in this way, the pinion rotates around the horizontal axis, and the horizontally moving rod, which has the second rack-shaped plate meshed with the pinion fixed at its end, moves towards the upper stile or It moves horizontally inside the lower stile, and this horizontally moving rod drives the pulling device.
This pulling device draws the upper stile or the lower stile toward the indoor side by abutting a movable part against the indoor side of an upper guide rail provided on the lower surface of the upper frame or a lower guide rail provided on the upper surface of the lower frame.

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

1 to 4 show embodiments of the invention. As mentioned above, the crescent metal fitting 10 when locking
(Figs. 12 to 15), the upper end base of the first rack-shaped plate 31 is attached to the lower end of the elevating rod 22b, which moves up and down inside the connecting frame 9a, by means of screws 32, 32. Fixed.

A plurality (four in the illustrated example) of rectangular through holes 33, 33 are formed at equal intervals in the narrow portion of the lower half of the first rack-shaped plate 31, and each through hole 3 is formed at equal intervals.
3 and 33 mesh with teeth 35b of a pinion 34, which will be described later.

On the other hand, a support bracket 36 made of a bent metal plate is fixed by screws 37 to the lower end of the matching frame 9a containing the lifting rod 22b. Two upper and lower horizontal shafts 38 and 39 are supported in parallel to each other on this support bracket 36.
On the upper horizontal shaft 38 of these, a pinion 34 is formed with two teeth 35a, 35b spaced apart from each other on the outer peripheral surface, and on the lower horizontal shaft 39, a protrusion 42 is formed in the center. The guide rollers 43 are each rotatably supported.

Furthermore, a second rack-like plate 41 is provided at the end of the horizontally movable rod 40 that is movable along the lower stile 7a (FIG. 17).
are fixed by screws 44, 44. The half portion of the second rack-shaped plate 41 closer to the tip is a narrow portion that is out of phase with the narrow portion of the lower end of the first rack-shaped plate 31 so as not to overlap with the narrow portion of the lower end of the first rack-shaped plate 31. A plurality of rectangular through holes 45, 45, into which the teeth 35a of the pinion 34 engage are formed at equal intervals.

The narrow portion of the second rack-shaped plate 41 in which the through holes 45, 45 are formed is sandwiched from above and below by the teeth 35a of the pinion 34 and the guide roller 43, so that the through holes 45, 45 and the teeth 35a are tightly held. I try to mesh with it. Also, the width of the first rack-shaped plate 31 is such that the second rack-shaped plate 41 swings laterally, and the side edge of the narrow part of the second rack-shaped plate 41 meshes with another tooth 35b. The side edge of the second rack plate 41 is held down by the protruding portion 42 of the guide roller 43 so that the narrow portion does not collide with the side edge.

As mentioned above, the horizontally movable rod 40 to which the second rack-shaped plate 41 is fixed at the end thereof is provided inside the lower stile 7a so as to be movable in the horizontal direction, and is moved in the direction of the arrow a in FIG. The movable parts of the pulling device are brought into contact with the indoor side edge of the upper end of the lower guide rail 30 on the upper surface of the lower frame 2, and the lower stile 7a is moved to the lower stile 7a. pull it indoors.

When the lifting rod 22b descends as the crescent fitting 10 rotates to the locked state, the pinion 34 rotates counterclockwise in FIG. 1 as the first rack plate 31 descends. Teeth 35 of pinion 34
The horizontally moving rod 40 is pushed in the direction of the arrow a in FIG. As a result, the lower stile 7a is drawn toward the indoor side.

In the illustrated embodiment, the first rack-shaped plate 31 is fixed to the lower end of the elevating rod 22b, which descends as the crescent fitting 10 rotates to the locked state.
Then, pull block 2 shown in FIG.
A drawing block 46 similar to 8b is fixed. As the lifting rod 22b descends, the pulling device at the intermediate portion of the lower stile 7a is driven to pull the lower stile 7a toward the indoor side, and at the same time, the inclined surface 47 formed at the lower end of the pulling block 46 is moved toward the lower frame 2. The upper end of the lower guide rail 30 on the upper surface is brought into contact with the indoor side edge, so that the lower end of the matching stile 9a is drawn toward the indoor side.

Circular holes 48 and 49 provided in the upper part of the drawing block 46 and the first rack-shaped plate 31 at mutually aligned positions allow screws 37 for fixing the support bracket 36 to be inserted, including their heads. It has an inner diameter that can be used.

In addition, it is driven in accordance with the horizontal movement of the horizontal moving rod 40, and moves a part of the movable parts to the lower guide rail 3.
The pulling device that brings the lower stile 7a into contact with the indoor side of the lower stile 7a and pulls it toward the indoor side of the lower stile 7a can have various shapes and structures, and some of them will be explained below.

First, FIGS. 5 to 7 show a first example of a pulling device. This first example consists of a roller 50 that rotates around a vertical axis that moves in parallel with the horizontal movement of the horizontal movement rod 40, and a wedge plate 55 that is fixed to the indoor side surface of the lower guide rail 30 on the upper surface of the lower frame. The structure is such that the lower stile 7a is drawn toward the indoor side (the right side in FIG. 5, the front side in FIG. 6, and the upper side in FIG. 7) by the abutment.

A horizontally movable rod 40 that fits inside the lower stile 7a and is only movable in the horizontal direction along the lower stile 7a.
A bracket 53 is fixed to the lower surface of the bracket 53 by screws 52, 52, and a roller 50 is rotatably supported on a vertical shaft 54 hanging from the lower surface of the bracket 53.

On the other hand, on the indoor side surface of the lower guide rail 30 on the upper surface of the lower frame, there is a wedge plate 55 with an inclined surface 56 at the portion that abuts the roller 50.
It is fixed by engagement with a through hole 57 bored in the hole 57 and tightening of a screw 58.

In the case of a pulling device using such a roller 50, when the crescent fitting 10 of the matching frame 9 is in the unlocked state, the roller 50 and the wedge plate 5
5 are separated from each other as shown in FIGS. 5 to 7, 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 40 is pushed to the right in FIG.
The vertical shaft 54 collides with the inclined surface 56 of the wedge plate 55, and as a reaction, supports the roller 50.
is pushed toward the indoor side, and the lower stile 7a is drawn toward the indoor side.

Next, FIGS. 8 and 9 show a second example of the pulling device. In this second example, a rotating plate 59 that rotates around a horizontal axis 66 as the horizontal movement rod 40 moves horizontally is used as the pulling device, and when locking, a tilted plate 59 is formed at the lower end of the rotating plate 59. Face 60
By abutting the upper end indoor side edge of the lower guide rail 30 on the upper surface of the lower frame, the lower stile 7a is drawn toward the indoor side (the front side in FIG. 8, the left side in FIG. 9).

That is, a rectangular through hole 6 is formed in the horizontal wall of the lower stile 7a.
1 is formed, and a holding bracket 64 having an outward flange 63 formed at the lower end of a long rectangular cylindrical portion 62 is fixed to this through hole 61 portion with screws 65, 65. A horizontal shaft 66 provided at the lower center of the elongated rectangular cylindrical portion 62 of the holding bracket 64 rotatably supports an intermediate portion of a rotary plate 59 having an inclined surface 60 formed at its lower end.

A pin 67 provided at the upper end of the rotating plate 59 and parallel to the horizontal axis 66 is connected to a long vertically extending pin 67 formed at the tip of a connecting bracket 68 that moves horizontally as the horizontally moving rod 40 moves horizontally. It is loosely mated with the hole 69.

The proximal end of the connecting bracket 68 is fixed to the end of the horizontally moving rod 40 by screws 70, 70. In addition, a guide pin 72 provided at the top of the long rectangular cylindrical portion 62 of the holding bracket 64 is loosely engaged with a horizontally long elongated hole 71 provided at the top of the connection bracket 68.
is made to move only in the horizontal direction.

Because of this configuration, when the horizontal movement rod 40 is moved to the right in FIG. The pin 67 is pushed to the right in the figure by the connection bracket 68, and the rotating plate 59 rotates clockwise in the figure.

When the rotating plate 59 rotates clockwise, the inclined surface 60 formed at the lower end of the rotating plate 59 and the upper indoor side edge of the lower guide rail 30 on the upper surface of the lower frame collide, and the lower stile 7a pull it indoors.

Furthermore, FIGS. 10 and 11 show a third example of the pulling device. In this third example, a toggle mechanism that expands and contracts in the vertical direction is provided in the middle part of the lower stile 7a, and this toggle mechanism is expanded and contracted as the horizontal movement rod 40 moves in the horizontal direction. When locking,
The lower stile 7a is pulled toward the indoor side by the collision between the inclined surface 80 at the lower end of the wedge-shaped drawing piece 73 pushed down by the toggle mechanism and the upper indoor side edge of the lower guide rail 30 on the upper surface of the lower frame.

That is, a holding bracket 77 having an outward flange 76 formed at the lower end of a long rectangular cylindrical portion 75 is fixed to an elongated rectangular through hole 74 provided in the horizontal wall portion of the lower stile 7a with screws 78, 78. .

A guide cylinder part 79 is provided at one end of the lower part of the long rectangular cylinder part 75, and a wedge-shaped pulling piece 73 having an inclined surface 80 formed at its lower end is fitted into this guide cylinder part 79 so as to be able to rise and fall freely. are doing.

The upper end of the lower arm 83 whose lower end is pivoted on the horizontal axis 82 at the top of the drawing piece 73 and the lower end of the upper arm 85 whose upper end is pivoted on the horizontal axis 84 at the upper part of the long rectangular cylinder part 75 are connected. They are rotatably connected by a shaft 86. This connecting shaft 86 is connected to the second
It fits into a slot 69 in a connecting bracket 68 similar to that in the example (see FIG. 8).

Because of this configuration, by rotating the crescent fitting 10 in the locking direction, the horizontally moving rod 40
When is moved to the right in Fig. 10, the upper and lower arms 85, 83 forming the toggle mechanism extend in a straight line,
Push down the pulling piece 73 and
The inclined surface 80 formed at the lower end of the lower stile 7a is brought into contact with the upper indoor side edge of the lower guide rail 30 on the upper surface of the lower frame, and the lower stile 7a is drawn toward the indoor side.

As shown by the chain line in FIG. 10, if the connecting bracket 68 is further extended in the opposite direction and this extended portion 87 is connected to the horizontally moving rod 40, the pulling piece 73 can be attached to the lower stile 7a (upper stile 7a). It is obvious that in the case of 6a, it can be configured in substantially the same way by turning the top and bottom upside down.) It can be provided at multiple locations.

In this case, the pulling piece 73 (same as the roller 50 and rotating plate 59) is attached to the upper and lower frames 6a,
If it is installed near both ends of 7a, the connecting stile 9a
It is no longer necessary to independently provide a device for drawing the vertical stile 8a toward the indoor side.

In addition, the power transmission device of the present invention (Figs. 1 to 4),
Lower stile 7a (or upper stile 6a) and vertical stile 8a (Figure 16)
It is also possible to provide a configuration in which a lifting rod is provided between the vertical moving rod 40 and moved up and down inside the vertical stile 8a in conjunction with the movement of the horizontal moving rod 40, and the movement of this 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 device of each sliding door shoji 5a, 5b independently, the pulling device of both sliding door shoji 5a, 5b is linked by operation of a single crescent metal fitting. It is convenient if an interlocking device is provided at the parts of the connecting frames 9a and 9b that face each other when the sliding doors are closed.

c. Effects of the invention The power transmission device for a sliding door shoji pulling device of the present invention is constructed and operates as described above.
It is possible to reliably draw the wide sliding door shoji, and the airtightness when locking is improved.
