Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an emergency opening device for a shoji in a sliding door that can be pivoted to open and close, which is used as an automatic door for a building or store, for example.

[Conventional technology]

Conventionally, as shown in Figures 6 to 9, the shoji 2 on both sides are normally fixed, and the central shoji 1 slides left and right to open (if there are two shoji, one is fixed and the other is fixed). (sliding), when taking in and out large items or in an emergency, shoji 2 on the fixed side and shoji 1 on the sliding side
There are known pivotable sliding doors that can open inward or outward. In these doors, the shoji 1 on the sliding side is usually suspended at two or more points on a hanging frame that slides along a rail above the opening, and if a predetermined force is applied in an out-of-plane direction, the shoji 1 will break at one end. The most common type is a type that is disengaged at a portion other than the hanging shaft and rotates around the hanging shaft.

[Problem that the invention attempts to solve]

By the way, such a sliding door that can be opened and closed by turning needs to be prevented from being opened and closed by turning inadvertently under normal conditions, and a mechanism that only prevents turning by using a Gremont lock or the like is desired.

In addition, in this type of door, it is difficult to lock the door at the central joining part, so a locking device such as a cylinder lock is often provided, for example, at the lower stile part of the sliding shoji. However, in the event of an emergency such as a fire after the door is locked, the cylinder lock on the lower stile must first be unlocked, and then the anti-swivel device must be unlocked, which prevents the door from fully functioning as a panic door. You end up not being able to perform at your best.

The emergency opening device for shoji screens of this invention solves the above-mentioned problems and can be easily operated from indoors.
The purpose of the present invention is to provide an entrance/exit door that can be unlocked and pivoted to open and close.

[Means for solving problems]

The device of this invention is suspended and supported by a hanging frame 30 that slides along a rail above the entrance/exit opening.
This is an emergency opening device for a shoji shoji, in which the upper part of the swivel side end of a shoji 1 that can be swiveled and opened and closed around a hanging shaft provided at one end is suspended and detachably supported by a support piece 31 hanging from a hanging frame 30. Inside the side vertical stile 1c is a Gremont lock 10 that can be operated from the indoor side to prevent the shoji from turning.
At the same time, 10 Gremon tablets are placed on the lower stile 1b.
A cylinder lock 20 is provided which can be interlocked with the cylinder lock 20.

Of the upper and lower rods 14a and 14b that can be moved in and out at the same time in the vertical direction, the upper end of the upper rod 14a can be freely engaged and detached from the vertical locking hole 33 provided in the support piece. The lower end of the side rod 14b can move in and out of a guide groove formed in the lower frame of the opening.

In addition, the cylinder lock 20 has one end of the swing lever 24 for moving the lock rod 27 in and out by operating the key.
In the locked state, it is brought close to the locking member 18 provided on the lower rod 14b of the Gremon lock 10,
As the rod b is pulled up, the cylinder lock 20

〔Example〕

Next, an illustrated embodiment (FIGS. 1 to 5) will be described.

Figure 5 shows a sliding door fitted with the device of this invention, viewed from the indoor side.Fixed side shoji 2 are fitted on both sides of the entrance/exit opening, and sliding side shoji 1 is fitted in the center. It can be opened and closed by rotating around the axis.

A Gremont lock 10 is installed inside the vertical stile 1c at the swing side end of the sliding shoji 1, and upper and lower rods 14a and 14b can be moved in and out vertically at the same time by operating a central knob 12. Furthermore, a cylinder lock 20 that can be operated from indoors and outdoors with a suitable key is attached to the swing-side end of the lower stile 1b.

As shown in FIG. 2, the upper part of the swing side end of this shoji 1 is a supporting piece 3 having an L-shaped cross section and hanging from a hanging frame 30.
1, and in this state, the hanging frame 30 slides along a rail (not shown) above the opening, and the shoji 1 is opened and closed in the lateral direction.

In the figure, numeral 3 indicates an engagement part attachment attached to the engagement part of this shoji 1, and 4 indicates a buffer material. Also, the engagement part attachment 3 includes a steel ball 5b and a steel ball 5b.
On the other hand, a guide roller 32 is attached to the tip of the support piece 31 to slide the engagement part attachment 3 during engagement and disengagement.

As shown in FIG. 1, the Gremont lock 10 has a central disc 15 that rotates together with the operating shaft 13 as the knob 12 rotates, and links 16a and 16b that connect the upper and lower rods 14a and 14b to the disc 15. Rods 14a and 14b can be moved up and down simultaneously. In addition, in the figure, 11 is the case of Gremon tablet 10, and 17a and 17b are the case of Gremon tablet 1.
This is a spring for holding 0 in either the locked position or the unlocked position.

The upper end of the upper rod 14a is connected to the support piece 31 mentioned above.
It can be freely engaged and detached from a vertical locking hole 33 that opens on the lower surface of the body. That is, when the Gremont lock 10 is locked, the rod 14a protrudes upward and locks the locking hole 33.
Since the shoji 1 is engaged inwardly, even if a force in an out-of-plane direction is applied to the shoji 1, it will not open in the turning direction. When the Gremont lock 10 is unlocked, the rod 14a is pulled and disengaged from the locking hole 33, so that it can be opened and closed by turning.

The lower end of the lower rod 14b can freely enter and exit the guide groove 8 formed in the lower frame of the opening, and when the Gremont lock 10 is locked, it slides within the guide groove 8.
It functions as a guide for the sliding of the shoji 1. In this embodiment, a cylindrical sliding member 19 is attached to the tip of the rod 14b (see FIG. 3).

As shown in FIGS. 1 and 4, the cylinder lock 20 is configured by inserting a suitable key into the key hole 22 and rotating it to move the lock rod 27 up and down and into and out of the receiving member 9 in the lower frame guide groove 8. It has a structure that allows Inside the case 21 of this cylinder lock 20, there is a connecting pin 2 that rotates around a rotating shaft 24a and a rotating shaft 25a, and has a long hole 24c at one end and a connecting pin 2.
The swing lever 24 and the second
A swing lever 25 is provided. Swing lever 2
4 has a locking pin 24b protruding in the thickness direction, and when the cylinder 23 rotates, the projection 2 of the cylinder 23
3a collides with this locking pin 24b, causing the swinging lever 24 to swing, and this swinging causes the coupling pin 25b to swing.
The movement is transmitted to the second swing lever 25 through the contact between the locking piece 25c at the other end and the locking groove 27a of the lock rod 27, and is converted into a vertical movement of the lock rod 27.

In addition, 26 in the figure is a spring for holding the lock rod 27 in either the locked position or the unlocked position, and 27b
21 is a locking pin protruding in the thickness direction of the locking rod 27;
A is a guide groove formed in the case 21 to guide the locking pin 27b.

In the above-described configuration, a locking end 24d is formed at the opposite end of the swing lever 24, and when the cylinder lock 20 is in the locked state shown by the dotted chain line in the figure, the Gremont lock, which is also in the locked state, is 10
The flange-like locking member 18 fixed to the outer periphery of the lower rod 14b comes close to the rod 14b.
Therefore, when the knob 12 of the Gremont lock 10 is operated to pull up the rod 14b from this state, the locking end 24d of the swinging lever 24 is also pulled upward, and the swinging lever 24 is pulled up from the rotating shaft 24a. Swinging around, unlocking Gremont lock 10 and cylinder lock 2
0 will be unlocked at the same time. In this state, if you push the turning side end of the shoji 1 and apply a force in an out-of-plane direction, the shoji 1 will turn around the hanging shaft at the other end,
It will open.

[Effect of idea]

With the emergency opening device for shoji of this invention, by simply operating the Gremont lock from the indoor side of a swingable sliding door, the cylinder lock for locking the door will be unlocked at the same time as the shoji swing end is released. ,
The shoji can be easily opened and closed in an emergency.
You can evacuate safely.

In addition, by keeping the Gremont lock locked at all times, you can prevent the shoji from being opened or closed carelessly, and the lower end of the rod on the bottom of the Gremont lock can be inserted into the guide groove of the bottom frame.
