Description

[Detailed explanation of the invention] a. Purpose of the invention (industrial application field) The sliding door shoji with a locking mechanism according to this invention is suitable for sweeping window type entrances and exits of balconies of schools, etc., breezeways, school lunch rooms, etc. It is attached to a sliding door or a window installed at a high place and used as an entrance for firefighting, and when the shoji is closed, the side of the stile of this shoji is pressed against the packing provided on the window frame side, soundproofing the inside and outside of the shoji. It is used to aim for.

(Prior Art) In a sliding door shoji called a so-called soundproof sash, when the shoji is closed, the side surface of the stile is pressed against a packing attached to a sash frame or the like facing the sill. For this reason, a locking device for fixing a soundproof sliding door shoji is provided with a locking mechanism for driving a pulling mechanism for moving the entire sliding door shoji in parallel toward the above-mentioned packing.

5 to 7 show a conventional sliding door shoji equipped with such a locking mechanism. First, a sliding door shoji having this conventional locking mechanism will be explained.

1 is a handle for operating the lock mechanism,
A base body 4 fixed with screws to the vertical stile 3 of the sliding door shoji 2
It is rotatably supported. An arm 6 having a roller 5 supported at its tip is provided at the base of the handle 1. Approximately
A receiver 9 having a letter-shaped projecting wall 8 is fixed with screws. The arm 6 supporting the roller 5 is
When the handle 1 is rotated about 150 degrees from the solid line position to the chain line position shown in FIG. 8. For this reason, the arm 6 is attached to the handle 1 so as to be freely rotatable by about 60 degrees. Due to the above-described engagement between the rollers 5 and the projecting wall 8, the vertical stile 3 of the sliding door shoji 2 approaches the connecting stile 7 by the length l in FIG. It is pressed towards the packing attached to the surface.

On the other hand, the end of the rotating shaft of the handle 1 described above is inserted into the base plate 10 of the locking device fixed inside the vertical frame 3, and a piece 11 that rotates with the rotation of the handle 1 is supported. . The end of this piece 11 is connected to a lower sliding plate 12 supported on the lower part of the base plate 10 so as to be able to move only in the vertical direction, by a link (not shown), and as the piece 11 rotates, the lower sliding plate 12 It is configured so that it moves up and down. The upper end of this lower sliding plate 12 is pivotally connected to one end of a rotary plate 13 whose center is pivoted to the base plate 10. Furthermore, the lower end of an upper sliding plate 14 supported on the upper part of the base plate 10 so as to be movable only in the vertical direction is pivotally connected to the other end of the rotary plate 13.

Because of this configuration, the above-mentioned handle 1
When the roller 5 and the receiver 9 are engaged by rotating, the upper sliding plate 14 and the lower sliding plate 12 mounted on the substrate 10 simultaneously move downward and upward, respectively. One end portion of a connecting rod 15 is connected to each of the upper and lower sliding plates 14 and 12, respectively. Vertical stile 3
Each connecting rod 1 arranged vertically inside the
The other ends of 5 and 15 are connected to shafts 16 at both the upper and lower ends of the vertical stile 3.
It is engaged with one end of a pulling piece 17 supported so as to be able to rotate freely around the center. Each pulling piece 17,
The other end of 17 faces the ridge 19 on the lower surface of the upper frame 18 or the indoor side surface of the door roller rail 21 on the upper surface of the lower frame 20. By rotating the handle 1, the roller 5 and the receiver 9 are engaged, and at the same time the upper sliding plate 14 is moved downward and the lower sliding plate 12 is moved upward, the upper end of the vertical frame 3 is pivoted. pulled piece 1
7 in the counterclockwise direction in FIG. 6 with the axis 16 as the center,
The pulling pieces 17 at the lower end similarly rotate clockwise, and the end of each pulling piece 17 abuts against the protrusion 19 or the indoor side surface of the door roller rail 21, pulling both the upper and lower ends of the sliding door shoji 2 into the room. It is moved inward (to the right in FIG. 6), and the indoor side surfaces of the upper stile 22 and lower stile 23 of this sliding door shoji 2 are pressed against the packing 24 attached to the upper frame 18 or the lower frame 20. Since the locking mechanisms are provided at both ends of the sliding door shoji 2, when the handles 1 of both locking mechanisms are rotated, the sliding door shoji is pressed against the packing 24 all around, thereby creating an airtight seal between the sliding door shoji and the window frame. By holding the sliding door shoji, soundproofing between the inside and outside is achieved.

(Problems to be Solved by the Invention) By the way, sliding shoji screens having a locking mechanism as described above are sometimes installed at entrances and exits of balconies or connecting corridors of schools, etc. In such a case, it is necessary to be able to lock the sliding door shoji from both the indoor and outdoor sides, but there has been no sliding door shoji that satisfies this requirement in the past. In other words, conventional sliding door shoji had operating handles only on the indoor side of the sliding door shoji and not on the outdoor side, so when closing the sliding door shoji from the outdoor side, each stile side of the sliding door shoji should be turned toward the packing. It cannot be pressed against the wall, making it impossible to achieve sufficient soundproofing indoors and outdoors.

In view of the above-mentioned circumstances, the present invention provides a sliding door shoji that has a locking mechanism with a locking device that can operate the locking mechanism for soundproofing from both indoors and outdoors and can be locked in the locked state. It is intended to.

b. Structure of the invention (Means for solving the problem) The locking mechanism with a locking device of the present invention, which is attached to a sliding door shoji having a locking mechanism with a locking device, is attached to both sides of the board that is attached and fixed to the inside of the vertical frame of the sliding door shoji. A pair of pieces are connected by a transmission mechanism such as a link or a gear, and rotate in opposite directions.By rotating the operating handle inserted through the center of rotation of each piece, the puller can be pulled. It is designed to drive the shifting mechanism. Further, a sliding plate that can freely slide on the board is provided near the part of the board that supports the pair of pieces, and when this sliding plate moves to one sliding end, the rotation of the pieces is controlled. A locking device is provided to prevent movement and hold the piece in a locked condition.

Furthermore, if necessary, the other end of the connecting arm, one end of which is pivoted at a portion away from the center of rotation of at least one of the pair of pieces, can be attached to the base plate so that it can move only in the vertical direction. The first sliding plate is engaged with the attached first sliding plate, so that the first sliding plate moves up and down with respect to the board as the piece rotates. The second sliding plate that moves vertically relative to the board in conjunction with the first sliding plate and the first sliding plate are connected by appropriate means, and each sliding plate moves against the board. It is configured to move at the same time. The other ends of the pair of upper and lower connecting rods, one end of which is connected to the first and second sliding plates that move simultaneously in this way,
Each is connected to a pulling mechanism provided at the upper and lower ends of the sliding door shoji.

In order to assemble the locking mechanism with the locking device configured in this way, the vertical frame for the hollow sliding door shoji, which is made by integrally extruding aluminum or the like, has a sufficiently large prospective dimension to support the periphery of the glass. A groove for this purpose is provided in the middle part of the inner surface. A pair of handles for driving the locking mechanism are mounted on the inner surface of the stile by screwing the base body to the portions located on the outdoor side and the indoor side of the groove. The rotating shaft of the handle, which is rotatably attached to a base screwed indoors and outdoors, is inserted into the inside of the vertical stile through a through hole formed on the inner surface of the vertical stile, and is attached to the locking mechanism. 1
It fits into a non-circular hole provided at the center of rotation of the pair of pieces.

Further, a knob called a thumb turn for driving the locking device is provided on the inner surface of the stile, located closer to the indoor side than the groove for holding the glass, or on the outer surface of the stile. In addition to this knob, the locking device can also be driven by a key, and the keyhole for inserting the driving key is opened on the side of the vertical stile opposite to the side where the knob is provided. . When the sliding door shoji of this invention is installed in a normal entrance or a low-rise part and used for a window that is opened and closed on a daily basis, the surface on which the knob is installed should be the indoor side of the inner side of the vertical stile, and the knob should be installed on the indoor side of the vertical stile. Make it operable. On the other hand, in the case of a sliding door shoji installed on a window that is installed in a high-rise area and used for fire department access, the knob is installed on the outside surface of the vertical stile so that the knob can be operated from the outside, and the knob can be operated from the outside to prevent danger. Therefore, the sliding door cannot be opened without the key.

Assembling the vertical stile 3, upper stile 22, and lower stile 23 formed as described above into a rectangular frame shape and holding glass inside to form a sliding door shoji is a conventional method shown in FIGS. 5 and 6. It is similar to sliding door shoji.

(Function) In the sliding door shoji having the locking mechanism with the locking device of the present invention constructed as described above, the pieces in which the rotating shafts of the pair of operation handles provided on the vertical frame are fitted are opposite to each other. Since it rotates in conjunction with the direction, if you rotate one handle, the other handle will also rotate in the opposite direction. Therefore, by operating one of the handles that are separately arranged on the indoor and outdoor sides of the sliding door shoji, the lock mechanism can be operated from either indoors or outdoors.

When opening and closing a sliding door shoji, by rotating one of a pair of handles installed indoors and outdoors, a pulling mechanism moves each frame of the sliding door shoji toward the opposing member. is driven.

Rotate each piece to the locked state by operating the handle, then drive the sliding plate with the knob or key, and move this sliding plate to one end to prevent each piece from rotating. The handle cannot be rotated.

The locking mechanism with a locking device configured as described above is attached to the inside of the vertical stile 3 of the sliding door shoji 2 as shown in FIGS. shall be. That is, the substrate 10
and a cover plate 58 are screwed together to form a casing,
This casing is screwed to the inside of the vertical stile 3. This vertical stile 3 has a larger expected dimension (width in the vertical direction in Figures 1 and 2) than the vertical stile used for conventional sliding door shoji, and has a peripheral edge of glass 59 in the center of the inner surface. A groove 60 is provided to support the. On the inside surface of the stile 3, there is sufficient mounting space for a handle to be provided on the outdoor side and the indoor side of the groove 60, and a pair of operating handles provided indoors and outdoors is provided. The base body 4, on which 1a and 1b are rotatably mounted, is fixed to this mounting location with screws. The rotating shafts of the handles 1a and 1b rotatably supported by each base 4 are inserted into the through holes formed in the side surfaces of the vertical frame 3 and the through holes formed in the cover plate 58, and are built into the lock mechanism. Piece 11
They fit into holes 25, 25 provided at the center of rotation of a, 11b. Among the handles 1a and 1b,
At the base of the handle 1b provided on the indoor side of the glass 59, an arm 6 with a roller 5 supported at its end is provided, as in the case of the conventional handle 1 shown in FIG. Further, the knob 55 for rotating the cylinder tube 53 from the indoor side is located in the groove 60 on the inner surface of the vertical stile 3.
The knob 55 is provided in the part located on the indoor side and above the handle 1b, and the key hole of the key receiver 61 into which the key for rotating the cylinder tube 53 from the outdoor side is inserted is inserted. Vertical stile 3 opposite to
It has an opening on the outer side.

A narrow convex portion 62 is formed on the outer side of the stile, which has a large projected size to house the lock mechanism, at a portion closer to the interior. This convex portion 62 is
Since the wide lock mechanism housing part cannot enter between the protrusions 64, 64 on the inner surface of the vertical stile 63, this is provided to narrow the width of the part that enters between the protrusions 64, 64. It is.

Since the sliding door shoji of the present invention having a locking mechanism with a locking device is constructed as described above, by rotating one of the pair of handles 1a and 1b provided inside and outside the sliding door shoji, The other handle also rotates in conjunction, allowing the sliding door shoji to be locked and unlocked from either indoors or outdoors.

That is, for example, when attempting to lock the sliding door shoji by rotating the handle 1b on the indoor side, the handle 1b must be moved from the solid line position to the chain line position, as in the case of the handle 1 of the conventional sliding door shoji shown in FIG. Rotate. As the handle 1b rotates in this manner, the piece 11b on the right side of FIG. 3 rotates clockwise from the position shown by the solid line in the figure to the position shown by the chain line, connecting the left and right pieces 11a and 11b. Connecting arm 27
a and 27b move upward. This causes the left piece 11a to rotate counterclockwise by the same angle.
When the connecting arms 27a and 27b rise, both arms 27
The end 28a of the shaft 28 connecting the shafts a and 27b moves to the upper end of the elongated hole 30 of the first sliding plate 29,
Further, by rotating the handle 1b, this first sliding plate 29 is pulled upward. Here, in order to prevent the first sliding plate 29 from being pulled up immediately after the connecting arms 27a, 27b are raised, the shaft 28 is
The reason why the hole with which the end of
This is because the distance by which the first and second sliding plates 29, 39 must be moved is small compared to the angle by which they must be rotated. Therefore, if it is desired to increase the distance by which both sliding plates 29 and 39 are moved during locking, the hole formed in the first sliding plate 29 for engaging the end portion 28a may be a simple circular hole, and the connecting arm This sliding plate 29 is made to be pulled up immediately after 27a and 27b are raised. Also, depending on the structure of the pulling mechanism provided at both the upper and lower ends of the sliding door shoji, the first and second sliding plates 29, 39 may be integrated so that both sliding plates 29, 39 move in the same direction. You can also do it. However, in any case, the shaft 2 connecting both connecting arms 27a, 27b
8 is movable only in the vertical direction of the substrate 10.
In the illustrated example, as the first sliding plate 29 rises, the second sliding plate 39, which is connected to the upper end of this sliding plate 29 via the rotary plate 34, descends. first,
Since the ends of the connecting rods 15 (FIGS. 5 and 6) are connected to the ends of the second sliding plates 29 and 39, the vertical movement of the sliding plates 29 and 39 described above Pulling pieces 17 (see FIGS. 5 and 6) rotate at both upper and lower ends of the sliding door shoji 2, and an action is performed to pull the sliding door shoji toward the room.

Next, if you want to lock the handles 1a and 1b so that they do not rotate in this state, you can do so by rotating the knob 55 from the indoor side or by rotating the key inserted into the key receiver 61 from the outdoor side. , cylinder tube 57
Rotate counterclockwise as shown in Figure 3. As a result, the third sliding plate 42 is lowered and this sliding plate 42
The blocking arms 45, 45 engaged with the lower ends of are rotated downward. For example, as the third sliding plate 42 descends, the blocking arm 45 located on the right side of FIG. The convex portion 65 formed at the end of the piece 11b comes to face.
In an attempt to release the lock from this state, piece 11b
Even if you try to turn the piece counterclockwise, the piece 11b
The convex portion 65 abuts against the end surface of the blocking arm 45, and the piece 11
b cannot be rotated, and therefore the lock cannot be released from either inside or outside.

When unlocking the lock and opening the sliding door shoji, it is sufficient to move each operation part in the opposite direction to the above case. This operation can be performed from either the indoor or outdoor side.

In the above embodiment, a link mechanism consisting of connecting arms 27a, 27b is used to rotate the pieces 11a, 11b mounted on the left and right sides of the board 10 in opposite directions. The transmission mechanism for rotating as described above is not limited to this type of mechanism, and for example, gears fixed to each piece 11a, 11b may be meshed with each other. Moreover, the first and second sliding plates 29,
39 in mutually opposite directions,
The present invention is not limited to the rotary plate 34, and for example, racks may be fixed at positions facing each other on each of the sliding plates 29, 39, and a pinion that meshes with both racks may be pivoted to the base plate 10. The locking device also has blocking arm 4.
5 and 45 may be omitted and a portion of the third sliding plate 42 may be configured to directly collide with the pieces 11a and 11b.

Furthermore, since the vertical stile 3 on the right side in FIG. 2 faces the matching stile 7 when the sliding door shoji is closed, the roller 5 as described above is used as a means for moving this vertical stile 3 toward the indoor side.
I used a combination of and receiver 9, but the left vertical stile 3
Since a faces the vertical frame 63 when closed, the vertical frame 3
A means for moving a towards the indoor side must be provided between it and this vertical frame 63. Of course, the support 9 may be fixed to this vertical frame 63 and engaged with the roller 5 provided at the base of the handle, but in the example shown in FIG. Instead, a cam body 66 as shown in FIG. 4 is provided on the outer surface of the vertical stile 3a, which moves up and down as the handle 1b rotates. This cam body 66 is connected to either the first or second sliding plate 29, 39 provided in the lock mechanism. On the other hand, a pin 6 is provided on the inner surface of the vertical frame 63 at a position facing the cam body 66.
7 is fixed. When either the handle 1a or 1b provided on the left vertical stile 3a for locking the sliding door shoji 2 is rotated, the cam body 66 provided on the outer surface of the vertical stile 3a rises or descends to move inside the vertical frame. The pin 67 on the side surface rides on the convex portion of the cam body 66, and as a reaction, the vertical stile 3a moves toward the indoor side.

c. Effects of the invention The sliding door shoji of the invention having a locking mechanism with a locking device is constructed and operates as described above, but the sliding door shoji can be locked and unlocked from either indoors or outdoors, and moreover, Since it can be locked in any state, if it is installed at the entrance to a school balcony, the sliding door can be locked even when people are out on the balcony, and soundproofing can be done indoors and outdoors.
