Description

[Detailed description of the invention] The present invention relates to a sliding door shoji that is slidably installed inside a sliding door.
The present invention relates to a locking device for holding the ventilation shielding plate in a blocking position in a sliding door with a ventilation section that is provided with a ventilation shielding plate that opens and closes the sliding door so as to be movable up and down.

When installing a ventilation blocking plate on a sliding door shoji to open and close the ventilation opening, the ventilation blocking plate should be installed within the width of the sliding door shoji so as not to interfere with the sliding of the sliding door shoji, and should be made thin so that it does not protrude beyond this width. must be formed.

Furthermore, when closing the ventilation opening with a ventilation shielding plate, it is preferable to lock the ventilation opening for security reasons.

Conventionally, there have been devices in which the ventilation shielding plate is made thin so that it fits within the width and thickness of the sliding door shoji, but a device that locks this has not yet been found.

This is because it is extremely difficult to fit the locking device within the width and thickness of the sliding door shoji.

The present invention solves this problem by providing a locking device within the width and thickness of the sliding door shoji, which can be automatically locked when the ventilation shield plate is raised or lowered, and can be easily unlocked. It is.

An embodiment of the present invention will be described below based on the drawings.
is the upper and lower rail member 3 of the sliding door outer frame 3 provided on the back door 2
This is a sliding door shoji installed so that it can be opened and closed along the lines a and 3a.The sliding door shoji 1 has a rectangular frame main body 4 whose middle part is divided by a middle crosspiece 5 as shown in FIG. A ventilation opening 7 is formed above the middle crosspiece 5, and the ventilation opening 7 is opened and closed for ventilation or non-ventilation by a ventilation shield plate 8 that is attached to the sliding door shoji 1 so as to be able to rise and fall freely. .

More specifically, an insect screen 9 is stretched over the ventilation opening 7, and rail grooves are provided on the inside surfaces of the left and right vertical frames 10, 10 of the frame upper body 4 on the indoor side of the ventilation opening 7. 1
1 and 11 (shown in Figure 3) are formed facing each other, and the edge frame 1
2 and a panel 13 of glass, decorative plywood, aluminum plate, etc. fitted in the edge frame 12 is attached to the rails 411, 11 so as to be movable up and down.

In order to fit this ventilation blocking plate 8 within the width and thickness of the sliding door shoji 1, the width and thickness of the middle crosspiece 5 is made thinner than the frame upper body 4, as shown in FIG. Care is taken so that the middle crosspiece 5 does not become an obstacle when the ventilation shielding plate 8 attached to the body 4 moves up and down.

Furthermore, the upper stile 14 of the frame upper body is also formed into a step-like recessed part 15 so as not to interfere with the raising and lowering of the ventilation shielding plate 8.

Further, a recessed portion 16 is formed on the indoor side surface of the middle crosspiece 5, and an abbreviated lock receiving plate 17 is formed at the bottom of this recessed portion 16 along the central crosspiece 5.
is fixed by a screw 1B, and a locking rib 19 projecting upward is integrally provided on this lock receiving plate 17.

On the other hand, the lower frame 20 of the ventilation shielding plate 8 is formed with a lock housing portion 21 facing the recessed portion 16, and a locking device 22 is housed in the lock housing portion 21.

This lock device 22 includes a lock housing 23 that is fitted and fixed in the lock storage portion 21, a claw metal fitting 25 that is rotatably pivotally attached to this lock housing 23 via a pin 24, and a locking metal fitting 25 that is permanently locked. The helical spring 27 that biases rotation toward the receiving plate 17 side and the unlocking finger hook pivotally connected to the lock housing 23 via a pin 28 are separated from the lever 29, and are attached to the lever 29 and the lock housing 23. are provided with arc-shaped elongated holes 30 and 35 that overlap with each other, and a connecting pin 31 protruding from the claw metal fitting 25 passes through and is engaged with both elongated holes 3G and 35, so that the ventilation blocking plate 8 is raised. When the claw metal fitting 25 is pressed, the claw metal fitting 25 is biased by the spiral spring 27.
The hook portion 32 automatically engages the locking rib 19 to maintain the ventilation blocking plate 8 in the raised position, thereby locking the ventilation opening 7 in the closed position.

Further, from this state, when the lever 29 for the finger hook is pulled toward the indoor side, the claw metal fitting 25 follows this and rotates backward against the bias of the helical spring 27, as shown in FIG. Locking rib 1
9, the ventilation shielding plate 8 descends due to its own weight and opens the ventilation opening 7.

This finger hook has a lever 29, a claw metal fitting 26 and a connecting pin 31.
The sliding door shoji 1 is normally completely housed in the casing 23 due to the biasing force of the spiral spring 27 through the sliding door frame 3.
When opening along the lever 29, there is no risk that the lever 29 will get caught on the building wall 26 (FIG. 1).

Note that 33 is a flange that protrudes around the indoor opening of the housing 23 and is fixed to the lower frame 20 with screws 34.

As described above, according to the present invention, the ventilation opening 7 is formed in the street half of the sliding door shoji 1 movably fitted to the sliding door outer frame 3, and the ventilation opening 7 and the lower half of the shoji 6, a hoistway 11 is formed on the indoor side approximately half the width and thickness of the sliding door shoji 1, and a ventilation shielding plate 8 is accommodated in this so as to be able to rise and fall freely.
A lock housing 23 that fits within the width and thickness of the ventilation blocking plate 8 is integrally provided at the lower end of the ventilation blocking plate 8, and within this lock housing, the lower end is pivoted to the lock housing 23 by a pivot pin 24. A claw metal fitting 25 that swings upward in a detachable manner is provided on the edge 19 of the ventilation opening as a fulcrum, and a helical spring 27 that urges the claw metal fitting in a direction to engage with the edge 19 is attached to the pivot point. It is wrapped around the support pin 24, and the upper end is also wrapped around another pivot pin 8.
A lever 29 is provided for the unlocking finger hook, which is pivoted to the lock housing 23 and swings downwardly with the pivot pin 28 as a fulcrum so that it can freely protrude into the room. The locking device for locking the ventilation blocking plate 8 is connected to the sliding door shoji 1.
It fits within the width and thickness of , and does not protrude beyond this, so that even though a locking device is provided, it does not interfere with the sliding of the sliding door shoji.

Furthermore, by raising the ventilation shielding plate δ, the claw metal fitting 25 in the lock housing 23 provided at the lower end of the shielding plate automatically closes the ventilation opening end of the sliding door shoji by the biasing force of the spiral spring 27. The ventilation blocking plate 8 is engaged with the edge 19 and locked.
It is very easy to operate because it prevents the lock from falling. Moreover, when unlocking the lock, the finger hook for unlocking inside the lock housing 23 simply pulls the finger towards the lever 29 and the claw metal fitting 25 is suspended. It can be removed from the ventilation opening edge 19 against the bias of the spring 27, and the unlocking operation can be easily performed.

In particular, according to the present invention, as mentioned above, the unlocking finger hook lever 2
9 is normally stored in the lock housing 23 and is biased by a spiral spring 27 via a connecting pin 31 and a claw metal fitting 25.
As mentioned above, this does not interfere with the sliding movement of the sliding door shoji 1, and when the door is unlocked, it swings downward using the pivot pin 28 as a fulcrum and protrudes toward the indoor side.
The amount of engagement of the fingertips on the lever 29 is increased, and the ventilation shielding plate 8 can be moved up and down in a stable manner.
