Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in an opening provided with a sliding door, presses a shoji (sliding door) in a closed position against an opening frame or another shoji to seal between the shoji and the opening frame or another shoji. The present invention relates to a shoji locking device for locking shoji.

[0002]

2. Description of the Related Art In a sliding door, rattling occurs in a strong wind, and the shoji flexes, so that it is easy for wind and rain to blow through the gaps formed between the shoji parts and the contact part between the shoji screen and the opening frame.
For this reason, in an opening having a large-sized shoji, a pulling device by pressing is arranged on the upper and lower parts of the shoji, and a locking device also serving as a pulling is arranged in the middle part, and the shoji has three or four points on one side. It is designed to attract people.

FIG. 4 shows an example of such a shoji pulling lock device, which is mounted inside the vertical frame 3 of the shoji 2 mounted on the opening frame 1 and is arranged above and below.
b), two locking devices 5 (a,
b) and the handle 6, the pulling device 4 and the locking device 5 are connected to the handle 6 by the upper and lower interlocking rods 7 (a, b). In FIG. 2, the shoji screen 2 is in the closed position, the handle 6 is pulled toward the front, and the shoji screen 2 is already pulled and locked.

That is, in this structure, when the handle 6 is pulled to the front, the pinion 8 is rotated and the upper interlocking rod 7a is moved downward, while the lower interlocking rod 7b is moved upside down.
As a result, the engaging claw 9 of the pulling device 4 rotates around the shaft 10 and moves from the position of the broken line to the outdoor side, and the tip end abuts against the fixing portion 11 provided on the lateral frame of the opening frame 1. When the anti-reverse movement further proceeds, the engaging claw 9 moves the shoji 2 indoors with the contact point with the fixed portion 11 as a fulcrum. This move
First, after the shoji 2 comes into contact with the opening frame 1 until it comes into contact with the opening frame 1, a contact operation is performed to further strengthen the contact. As a result, the upper part and the lower part of the shoji screen 3 are pressed against the opening frame 1 side and brought into a drawn state.

At the same time, the engaging arm 12 of the lock device 5 is also rotated from the broken line position to the solid line position, and the engaging portion 13 (roller) at the tip of the engaging arm 12 is an arcuate receiving member fixed to the opening frame 1. The tool 14 is contacted. As a result, the intermediate portion of the shoji screen 2 is also pulled toward the opening frame 1 and the engaging portion 13
It is locked by the engagement between the engaging arm 12 and the receiving tool 14 via the.

For design reasons, the rotating shaft of the handle 6 is often arranged coaxially with one of the locking devices 5 (a, b), but the structure is complicated, so it is arranged separately in FIG. Is shown. Further, the structure in which the interlocking rod 7 (a, b) is moved up and down in an anti-reverse manner is not limited to the rack and pinion structure.

As described above, the shoji 2 can be attracted and locked by pulling only one handle 6. However, the engaging operation of the engaging claw 9 of the attracting device 4 and the engagement of the locking device 5 are performed. If it is difficult to adjust the locking operation of the coupling arm 12 and the engaging portion 13 at the tip of the engaging arm 12 reaches the contact position with the receiving tool 14 before the shifting operation is sufficiently performed, the engaging portion 13 will be It collides with the starting end of the receiving tool 14 and further pulling and locking are impossible. Regardless of this state, if the handle 6 is forcibly rotated, the pulling device 4, the locking device 5, the handle 6, or the like is deformed or damaged.

Further, although the shoji screen 2 has already been drawn to the close contact state by the pulling device 4, the shoji screen 2 is further pulled at the position of the locking device 5 due to the delay in the rotation of the engaging arm 12. Similarly, when pulling, an excessive force acts on the attracting device and the locking device. Furthermore, it is difficult to stop the handle at the correct lock position even if the pulling operation, the close contact operation, and the lock operation of the lock device are performed with good timing. It is often.

The engaging claw 9 is normally retracted to the position of the chain line due to weight balance and does not project from the upper surface of the opening frame 1, but when the cam roller 15a linearly moves downward, the engaging claw 9a is rotated to the left. The tip projects from the opening frame 1 and moves in the outdoor direction.

The fixed portion 11a is the upper horizontal frame 1 in the opening frame 1.
It is formed integrally with a and protrudes toward the inner peripheral side, and the engaging claw 9
It corresponds to the position where the tip of a projects. The lower attracting device 4b has the same structure as the upper attracting device 4a, although the placement is vertically symmetrical. It is assumed that the parts having the same function are given the additional symbols a and b to distinguish them from each other, and the same symbols are used.
Detailed description is omitted.

The handle 6 is rotatably attached to a fixed position of the vertical frame 3 so that the drive gear 1 is attached to the shaft 16.
7 also meshes with a pinion 8 that is axially mounted at a fixed position on the vertical frame 3. The pinion 8 has racks 18 (a,
b) is engaged, and the handle 6 is rotated so as to make an anti-reverse movement in the vertical direction. The upper interlocking rod 7a is connected to the rack 18a, and the lower interlocking rod 7b is connected to the rack 18b. A recess 19 is provided in the middle of the interlocking rod 7 (a, b).

Is provided. The fixed-side metal member 23 is fixed to the prospective wall in the indoor / outdoor direction of the opening frame 1 or the other side frame (fixed-side member) of the shoji screen by the substrate 22, and the receiver 14 is raised from the substrate 22 in a semicircular shape. However, the arcuate circumferential surface is the cam surface. The engaging arm 12 is rotatably attached to the prospective indoor / outdoor direction wall of the vertical frame 3 (summing frame) of the shoji 2 by the shaft 24, and the abutting portion 25 is provided at the outdoor side end.
An engagement portion 13 (roller) is axially attached to the indoor side end.
This structure is the same for the lower lock device 5b.

Now, assuming that the handlebar 6 is pushed to the outside and is not pulled in immediately after the shoji 2 is closed, the slide plate 20 in the interlocking rod 7a is shown in FIG.
In the state of (a), since the cam roller 15 of the engaging claw 9a of the drawing device 4a is moving upward, the tip end thereof is at the broken line position due to its own weight and is retracted from the fixed portion 11 of the opening frame 1. ing. In addition, in the lock device 5a, the contact portion 25
Is pulled upward and the engagement arm 12 is in the state of being rotated to the right. The slide plate 20 on the lower interlocking rod 7b, the engaging claw 9b of the lower pulling device 4b, and the engaging arm 12 of the lower locking device 5b are in the same state except that the directions are different.

In this state, when the handle 6 is pulled to the front, the pinion 8 is rotated to move the upper interlocking rod 7a downward,
On the other hand, the lower interlocking rod 7b is moved upward. As a result, the engaging claw 9a of the upper pulling device 4a pivots about the shaft 10 and moves from the position indicated by the broken line to the outdoor side, and the tip end portion of the opening frame 1 is opened.
It abuts against the fixed portion 11a. Further, when the upper interlocking rod 7a is moved downward and the lower interlocking rod 7b is moved upward, the engaging claw 9a
Moves the shoji 3 indoors using the contact point with the fixed portion 11 as a fulcrum. This movement includes first a closing operation until the shoji 3 comes into contact with the opening frame 1 and a close operation for further strengthening the contact. As a result, the upper and lower portions of the shoji screen 3 are pressed against the opening frame 1 side, and pulling is performed.

Then, the engaging portion 13 attached to the indoor end of the engaging arm 12 moves along the attracting surface of the receiving tool 14, and the arcuate bulge of the attracting surface causes the shoji central portion to be attracted and locked ( Lock direction operation Fig. 3 b → c). In the meantime, the pulling device 4a performs a close contact operation, and the shoji screen 2 as a whole is brought into close contact with the vertical frame of the opening frame 1 or the vertical frame (summing frame) of the adjacent shoji screen.

In this operation, when the engagement arm 12 of the lock device 5a is rotated, the shoji 2 is pulled toward the opening frame 1 by the upper and lower pulling devices 4 (a, b). The engaging portion 13 of the coupling arm 12 is smoothly guided to the pulling surface without colliding with the end portion of the receiving tool 14. On the other hand, the engaging claw 9a in the pulling device 4a
Also, since the engaging portion 13 of the engaging arm 12 is smoothly guided to the pulling surface, the contacting operation is smoothly performed, and an excessive force acts on the pulling device 4, the locking device 5, or the handle 6. There is no.

To release the sliding door 2 from the locked state, the handle 6 pulled indoors is pushed outward. Then, the interlocking rod 7a moves upward, and the slider 20 moves the distance d1 from the state shown in FIG. 3C to the state shown in FIG. During this time, the pulling device 4a releases the contact, but the locking device 5a is not driven. When the handle 6 is further moved to the outdoor side, the contact portion 25 is pushed up,
Return to the state of (a). The engaging arm 12 rotates clockwise to disengage the engaging portion 13 from the drawing surface of the receiving tool 14, and the cam roller 15 at the tip of the interlocking rod 7a also moves sufficiently upward. As a result, the shoji 2 is freed from the opening frame 1, the engaging claw 9a is rotated rightward by its own weight and retracts from the fixing portion 11 of the upper lateral frame 1a, and the opening / closing operation of the shoji 2 is not hindered.

In this case, since the position of the handle 6 and the position of the lock device 5a (or 5b) match, the design of the opening can be made neat.

[0037]

According to the first aspect of the present invention, since the locking operation of the locking device is performed after the drawing operation of the drawing device, the transition to the close contact operation and the locking operation of the drawing device is smooth. The pulling device, the locking device, and the handle portion for driving them are hardly deformed or damaged. A locking device with a pulling device on the top and bottom of the shoji screen and a pulling function on the vertical middle part of the shoji screen prevents backlash and gaps during strong winds even with a large shoji screen can do.

By forming the concave portion in the interlocking rod, it is possible to obtain an operation delaying mechanism with a simple structure for causing the locking device to perform the locking operation after the drawing device has been moved to the close position. When the locked state is released, the dimension d1 of the concave portion causes the release of the close contact state by the pulling device to precede the lock release operation of the lock device, and the release of the close contact state and the lock release operation overlap, which makes the handle operation heavy. You can avoid becoming.

According to the structure of the second aspect, the initial resistance of the handle operation is small due to the recess provided in the interlocking rod, and the handle can be operated lightly and reliably. Further, if a pulling device is attached to the end of the interlocking rod, the shoji can be pulled and locked at the same time with a single handle operation. According to the configuration of claim 3, since the operating range of the handle is defined by the stopper,
It is possible to always accurately and accurately lock and unlock the shoji with respect to the opening frame.
