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. A substantially L-shaped protruding wall 8 is formed on the side surface at the same height as the base body 4 on the side surface of the vertical frame or mating direction 7 facing the vertical frame 3 to which the base body 4 for supporting the handle is fixed. A receiver 9 is fixed with screws. Arm 6 supporting the roller 5 mentioned above
When the handle 1 is rotated approximately 150 degrees from the solid line position shown in FIG. The projecting wall 8 is engaged with the projecting wall 8. For this reason, the arm 6 is attached to the handle 1 so as to be freely rotatable by about 60 degrees. The roller 5 and projecting wall 8 mentioned above
Due to the engagement with the sliding door shoji 2, the vertical stile 3 of the sliding door shoji 2 approaches the mullion 7 by the length shown in FIG.
The side surface of the vertical stile 3 is pressed toward the packing attached to the side surface of the mullion.

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. 9 centering on the axis 16,
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. The sliding door shoji 2 is moved inward (right side in FIG. 9), and the indoor side surfaces of the upper stile 22 and lower stile 23 of the sliding door shoji 2 are pressed against the packing 24 attached to the upper frame 18 or the lower frame 20. Since the locking devices are provided at both ends of the sliding door shoji 2, when the handles 1 of both locking devices are rotated, the sliding door shoji is pressed against the packing 24 all around, thereby creating an airtight gap between the sliding door shoji and the window frame. By holding the sliding door shoji, soundproofing between the inside and outside is achieved.

(Problem to be solved by the invention) By the way, in order to effectively soundproof the sliding door shoji using the locking device as described above, it is necessary to place the locking device on either the left or right vertical frame of the sliding door shoji 2 as described above. As shown in FIG. 7, which shows an embodiment of the present invention, each vertical frame 3, 3a must be provided with a handle 1 for operating the locking device.

However, by providing the handles 1 for operation on both the left and right vertical frames 3 and 3a,
Conventionally, the following disadvantages occur.

That is, when closing a sliding door shoji that has been in an open state until then, the user hooks his/her finger on the vertical stile 3a facing the vertical frame 25 or the handle 1 provided on this vertical stile 3a,
This vertical stile 3a is moved toward the vertical frame 25,
If you move this movement vigorously, vertical frame 3 will become vertical frame 25.
The block collides with the inner surface of the frame 3a or the blocks fixed to the upper and lower frames 18, 20, and then bounces back with the force of the collision, resulting in a gap greater than a predetermined distance between the vertical frame 3a and the vertical frame. In this state, when you lock the sliding door shoji with the handle 1 on the side of the vertical stile 3a that you were holding your fingers to move the sliding door shoji, even though the sliding door shoji 2 is not completely closed, this sliding door shoji 2 Packing 2 attached to the inner surface of each frame and window frame

In an attempt to operate the handle 1 provided on the vertical stile 3 facing the gathering mullion 7 and engage the roller 5 provided on the arm 6 at the base of this handle with the receiver 9 fixed to the gathering mullion 7. Also, the roller 5 is connected to the projecting wall 8 of the receiver 9.
As a result, it becomes impossible to perform a locking operation on the side of the vertical stile 3 that faces the mullion 7.

The sliding door shoji lock device of the present invention is intended to eliminate the above-mentioned disadvantages.

b. Structure of the invention (Means for solving the problem) The locking device for sliding door shoji of the present invention includes a handle provided on the stile, which is fixed to the inside of the stile facing the vertical frame when the sliding door shoji is closed.

An anchor fitting 26 is fixed to the inner surface of the vertical frame 25 between the vertical frame 3a and the vertical frame 25 which face each other when the sliding door shoji 2 is closed. This anchor fitting 26 is made by bending the end of a folded piece 28 at a right angle from the side edge of the base plate 27 to be fixed to the inner surface with screws, and further bending the end at a right angle to form an engaging plate part 29. By slightly bending the lower end portion outward, an inclined portion 30 is provided which is inclined so that it becomes farther from the substrate portion 27 toward the lower end. Further, a roller 31 serving as an abutment piece is rotatably supported at the lower part of the base plate portion 27.

On the other hand, a shifting metal fitting 32, which is provided on the side of the vertical stile 3a and can be raised and lowered by rotating the handle 1 that operates the locking device, is fixed with screws to the outer surface of a lifting block 33 that is provided on the vertical stile 3a and can be raised and lowered. are doing.

As in the case of the anchor fitting 26 described above, the biasing metal fitting 32 is made by folding the end of the folded piece 35 which is folded at right angles from the side edge of the base plate part 34 and further bending it at a right angle to form a sliding contact piece 36. By slightly bending the upper end portion outward, the inclined portion 37 is inclined so that the closer it is to the upper end, the farther it is from the substrate portion 34.
has been established. The lift block 33 for fixing the offset fitting 32 constructed in this way to the outer surface is integrally formed of nylon or other synthetic resin, and the center of the outer surface has a concave portion 38, and the above-mentioned offset fitting 32 is It is fixed to the inner upper part of this recess 38. A collision protrusion 3 is provided on the lower indoor side of the recess 38.
9 is formed. In order to lock the sliding door shoji 2, when the handle 1 is rotated and the lifting block 33 is raised, this abutting protrusion 39 collides with the inner side of the roller 31 of the anchor fitting 26 and becomes vertical. This is for moving the stile 3a toward the indoor side (lower side in FIG. 2), and the upper inner surface that abuts against the roller 31 is an inclined surface 40 that slopes downward toward the center of the lifting block 33.

Vertical stile 3 to which such a lifting block 33 is attached
The vertical sides 41, 41 of a have elongated holes 4 that are long in the vertical direction.
2, 43 are formed, and the elevating block 33 is fitted inside each elongated hole 42, 43 so as to be able to freely slide slightly in the vertical direction. The inner end of the lifting block 33 is connected to the lower end of the lifting arm 45 via a spacer 44, and the lifting arm 45, which is raised and lowered by rotation of the locking device operating handle, connects to a collision protrusion provided on the outer surface. 39 and the one-sided fitting 32 are moved up and down.

The structure of the handle operating portion that raises and lowers the lifting arms 45 by rotating the handle 1 is as shown in FIGS. 5 and 6, for example, as shown in FIGS. pieces 47a, 47
I am wearing b. Each piece 47a, 47b is formed into a Daruma shape as a whole, and has a non-circular hole 4 at the end, which is the center of rotation, for inserting the operating handle.
It has 8. Holes 48 of those pieces 47a, 47b
One end of connecting arms 49a, 49b constituting a link mechanism is pivotally supported by a shaft 50 at a portion slightly away from the link mechanism. Further, the other ends of each connecting arm 49a, 49b are connected to each other by a shaft 51, and the shaft 51 projects from the end 5 of each connecting arm 49a, 49b.
1a is engaged with a long hole 53 of a first sliding plate 52 that is supported by the lower part of the substrate 46 so as to be movable up and down. Further, a portion of this end portion 51a that protrudes beyond the first sliding plate is locked to the upper end portion of the elevating arm 45 described above. 54 is a vertically long long hole bored in the first sliding plate 52, and 55 is an elevating arm 45.
Both long holes 54,
55 and pins 56, 56 planted on the substrate 46 are engaged.

On the other hand, a horizontally long elongated hole 57 is formed at the upper end of the first sliding plate 52, and a pin 58 provided at one end of the rotary plate 13 engages with this elongated hole 57. This rotary plate 13 is rotatably supported on the substrate 46 by a shaft 59 provided at the center, and a similar pin 60 is provided at the other end. This rotating plate 1
A pin 60 provided at the other end of the board 46 engages with a horizontally elongated hole 62 provided in the middle of a second sliding plate 61 provided vertically slidably on the top of the board 46. There is. Pins 64 , 64 erected on the base plate 46 are respectively engaged with vertically elongated holes 63 , 63 formed in the upper and lower parts of the second sliding plate 61 . can only be moved in the vertical direction with respect to the substrate 46.

However, the means for rotating the pair of pieces 47a, 47a in opposite directions is not limited to the link mechanism shown in FIG. Fixed gears may be meshed with each other. Also, the first and second sliding plates 5
2 and 61 in opposite directions to each other is not limited to the rotary plate 13 shown in FIG. It is also possible to construct a structure in which the racks fixed to the lower part of the base plate 61 are engaged with each other via a pinion supported on the base plate 46.

The handle operation portion configured in this way is attached to the inside of the vertical stile 3a of the sliding door shoji 2 as shown in FIG. That is, the base plate 46 and the cover plate 65 (FIG. 6) are screwed together to form a casing, and this casing is screwed inside the vertical frame 3a. In the illustrated embodiment, in order to be able to lock the sliding door shoji from either the inside or outside of the sliding door shoji, the estimated dimensions (up and down in Fig. A vertical stile 3a having a large width (direction width) is used, and this vertical stile 3a secures sufficient mounting space for the glass 66 on the outdoor side and the indoor side. The rotation shafts of the pair of operating handles 1, 1 provided indoors and outdoors are inserted through holes formed in the side surface of the vertical stile 3a and the cover plate, and are fitted into the holes 48, 48 of the pieces 47a, 47b. There is.

The handle operation part of the locking device for sliding door shoji constructed as described above and assembled to the sliding door shoji is operated by rotating one of the pair of handles 1 and 1 provided on the interior and exterior of the sliding door shoji. In this case, 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 trying to lock the sliding door shoji by rotating the handle 1 on the indoor side, the handle 1
As in the case of the handle 1 shown in FIG. 10, rotate it to the position shown by the solid line and the position shown by the chain line. As the handle 1 rotates in this manner, the piece 47b on the right side of FIG. 5 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 47a and 47b. The connecting arms 49a, 49b move upward. This causes the left piece 47a to rotate counterclockwise by the same angle. When the connecting arms 49a, 49b rise, the elevating arm 45 also rises, and the end 51a of the shaft 51 connecting the arms 49a, 49b moves to the upper end of the long hole 53 of the first sliding plate 52. Thereafter, by further rotating the handle 1, the first sliding plate 52 also rises together with the elevating arm 45, which has started rising in synchronization with the rotation of the handle 1. Here, in order to prevent the first sliding plate 52 from being pulled up immediately after the connecting arms 49a, 49b are raised, the reason why the hole with which the end of the shaft 51 engages is set as the elongated hole 53 is that the roller 5 and The first and second sliding plates 52, 6 are smaller than the angle at which the handle 1 must be rotated and the distance at which the lifting block 33 must be raised to engage the receiver 9.
This is because the distance that 1 must be moved is small. Therefore, when locked, both sliding plates 52 and 61
If it is desired to increase the distance of movement of the connecting arms 49a, 49, the hole formed in the first sliding plate 52 for engaging the end portion 51a may be a simple circular hole, and the connecting arms 49a, 49
This sliding plate 52 is made to be pulled up immediately after b is raised. Further, 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 52 and 61 may be integrated and both plates may be movable in the same direction. However, in either case, the shaft 51 connecting the connecting arms 49a, 49b is movable only in the vertical direction of the substrate 46. In the illustrated example, as the first sliding plate 52 rises, the second sliding plate 61, which is connected to the upper end of this sliding plate 52 via the rotary plate 13, descends. first,
Since the ends of the connecting rods 15 (Figs. 8 to 9) are connected to the ends of the second sliding plates 52 and 61, the vertical movement of the sliding plates 52 and 61 described above Pulling pieces 17 (FIGS. 8 and 9) 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 indoor side. Furthermore, as the elevating arm 45 rises, the inclined surface 40 of the abutting protrusion 39 of the elevating block 33 fixed to the lower end of the elevating arm 45 via the spacer 44 collides with the roller 31 on the inner surface of the vertical frame. As a result, the vertical stile 3a is pushed toward the packing 24 toward the indoor side (lower side in Figure 2), but the inner surface of each stile of the sliding door shoji 2 comes into contact with the packing 24, causing the sliding door shoji 2 to move laterally. Vertical frame 25 before is restricted.
The sloped part 30 of the anchor fitting 26 is fixed to the inner side of the
The sliding door shoji 2 is completely moved to the closed position by engagement with the inclined portion 37 of the biasing fitting 32 which rises as the lifting block 33 rises.

Note that the above-mentioned embodiment shows a structure in which operating handles are provided inside and outside the sliding door shoji so that the locking operation of the sliding door shoji can be performed from either the inside or outside of the shoji. The locking device for sliding door shoji is not limited to this structure,
As shown in FIG. 8, the present invention can also be applied to a sliding door shoji in which the operating handle 1 is provided only on the inside.

c. Effects of the invention Since the locking device for sliding door shoji of the present invention is configured and operates as described above, when the sliding door shoji is locked, it can be completely moved to the closed position, and the sliding door shoji can be completely moved to the closed position, and the sliding door shoji can be moved completely to the closed position. or stile)
The sliding door shoji can be reliably locked without becoming unable to operate the side handle.
