Description

[Detailed description of the invention] This invention relates to an interlocking sliding door device.

As shown in Figures 1 and 2, a sliding door device for opening and closing the opening of a storage space such as a storeroom has conventionally been an interlocking type that consists of an inner sliding door, a middle sliding door, and an outer sliding door that interlock with each other during opening and closing operations. better known.

In this interlocking sliding door device, stoppers 4a and 4b are provided on one side edge of the inner sliding door 1 and the middle sliding door 2, respectively, and the three sliding doors, the inner sliding door 1, the middle sliding door 2, and the outer sliding door 3 are overlapped on the left door contact part 5a side. The opening 6 shown in FIG.
By pulling the outer sliding door 3 toward the right door stop 5b from the open state, the left edge hook 3a of the outer sliding door 3 is engaged with the stopper 4b of the inner sliding door 1, and then the left edge hook of the inner sliding door 2 is engaged with the stopper 4b of the inner sliding door 1. The part 2a is engaged with the stopper 4a of the inner sliding door 1 to close the openings 6 of the outer sliding door 3 and the inner sliding door 2 in this order as shown in FIG. By pulling toward the contact part 5a, the right edge hook part 3b of the outer sliding door 3 comes into contact with the stopper 4b of the middle sliding door 2, and the middle sliding door 2 follows the outer sliding door 3, and the left door contact part 5a is pulled.
The opening 6 can be opened by being pulled back until the opening 6 is opened, and handles 7 and 8 are provided on the front right side of the outer sliding door 3 and on the front left side of the inner sliding door 1 for opening and closing. Each is provided.

However, in such a conventional interlocking sliding door device, when the outer sliding door 3 is pulled forcefully during the closing operation as shown in FIG. This has the disadvantage that the door does not stop at the closed position and shifts toward the right door abutment 5b, creating a gap and making it impossible to close the door correctly.

Such inconveniences occur not only when the closing operation is strongly performed, but also when the opening 6 is installed in an inclined state.

Inner sliding door 1 and outer sliding door 3 of the interlocking sliding door device
Although it is possible to prevent the above-mentioned inconvenience by separately providing locks 9 and 10 and locking the inner sliding door 1 and the outer sliding door 3 at the left door stop 5a and right door stop 5b of the opening 6, In this case, in order to prevent the sliding door from shifting when closed, the sliding door must be locked at all times, which has the disadvantage that the operation becomes troublesome.

Therefore, the purpose of this invention is to provide an interlocking sliding door device that allows each sliding door to open and close correctly without shifting from its predetermined position and stopping, has a good appearance, and has excellent security. It is.

An embodiment of this invention is shown in FIGS. 3 to 5. That is, this interlocking sliding door device has handles 11, 11 rotatably provided on the front left side of the inner sliding door 1 and the front right side of the outer sliding door 3 in the conventional example, and Each of the handles 11, 11 protrudes from the back side of the sliding door 3.
A locking hook 12 is provided at the rear end of the shaft portion of the handle 11, and a locking hook 12 is provided at the rear end of the shaft, and locking holes (see FIG. (not shown) so that the locking hook 12 can be locked.

The handle 11 is a cylinder 11 in the shape of a shallow circular dish.
a and a knob 11b rotatably attached to the cylinder 11a, and a locking mechanism is provided on the shaft portion of the knob 11b to hold the locking hook 12 in a rotational position where it locks in the locking hole. are doing. In FIG. 5, 13 is a keyhole for operating the lock mechanism.

The other configurations are the same as those of the conventional example.

With this configuration, the handle 11 of the inner sliding door 1
By rotating the knob 11b as shown in FIG. 6 and locking the locking hook 12 in the locking hole of the left door contact part 5a of the opening 6, the inner sliding door is closed when the outer sliding door 3 is opened and closed. 1. The inner sliding door 2 can be opened and closed in the correct position without shifting. When you want to open the inner sliding door 1 side of the opening 6, use the handle 11.
By rotating the knob 11b, the locking hook 12 can be easily unlatched from the locking hole of the left door stop portion 5a, making the opening and closing operations easier.
Even when the sliding doors are arranged at an angle, the sliding doors do not shift in position and create gaps.

Further, since the locking hook 12 is hidden behind the inner sliding door 1 and the outer sliding door 3, the appearance of the sliding door is good.

Furthermore, since the handle 11 and the locking hook 12 are integrated, installation is easy.

Furthermore, a locking mechanism is installed on the shaft of the handle 11, and a keyhole 13 for operating the locking mechanism is provided on the front of the handle 11, so it can be closed and locked if necessary, making it easy to use. ,
Excellent in terms of crime prevention.

In addition, in the embodiment described above, the handle 11 is formed of a dish-shaped cylinder 11a and a knob 11b.
In addition, as shown in FIG. 7, a cylindrical handle 11' having a knurled peripheral surface may be used. In the case of this handle 11' as well, a locking mechanism is provided on the shaft portion thereof, and a keyhole 13' is formed in the front surface of the handle 11'. 12' is a locking hook provided at the rear end of the shaft portion of the handle 11'.

When this handle 11' is used, the effect is similar to that of the previous embodiment.

As mentioned above, the interlocking sliding door device of this invention is
An interlocking sliding door device in which an inner sliding door, a middle sliding door, and an outer sliding door can be opened and closed in conjunction with each other, and a locking hole provided on the back side of the inner sliding door and the outer sliding door in the left and right door stop portions; A handle rotatably provided on the front side of the inner sliding door and the outer sliding door that approaches the left and right door stops in the closed state, and a handle provided on the back side of the inner sliding door and the outer sliding door that is driven by the handle. a locking hook that engages and disengages from the locking hole of the door stop portion;
The handle includes a lock mechanism that locks the locking hook in the locking hole, and a keyhole that operates the lock mechanism that is installed on the front surface of the handle. Each sliding door does not shift its position during operation, allowing reliable opening and closing operations, and even when installed at an angle, the inconvenience of sliding doors opening by themselves can be avoided, making it easier to use. The locking hook is hidden on the back of the sliding door, giving it a good appearance, and since it is provided with a locking mechanism and a keyhole, it can be closed and locked if necessary, and has the effect of being excellent in crime prevention.
