Description

[Detailed description of the invention] This invention is a door that opens and closes by sliding, but can also be opened and closed by swinging if necessary. The present invention relates to a door opening/closing device that allows for easy exit by operating a touch part.

The applicant has already proposed a door that can be opened and closed by sliding as shown in FIGS. 1 to 3 as well as by swinging. In this case, a hanging frame 4 is suspended from an upper rail 2 in a blind 1 via pulleys 3, 3, and a door 5 is further suspended from this hanging frame 4. As the driving device 6 rotates forward and reverse, the left and right doors 5, 5 slide to open and close along the closing doors 9, 9 via the belts 7, 7 and pulleys 8, 8.

Here, when transporting large items in and out, or when an abnormal situation such as a fire occurs, etc.
When a larger opening than the door 5 is required, as shown in FIG. 3, when the door 5 is pushed outward, the engaging portions 14, 14 of the door 5 with the hanging frame 4 are disengaged, and the swing fulcrum portion 10, 10 as the center, and as the door 5 swings, the fitted door 9 is also pushed out and swings around the upper and lower pivoting fulcrums 11, 11, 12, 12. Even when the doors 5, 5 remain open, they slide to the positions of the pillars 13, 13 on both sides, and a frontage twice as large as usual is obtained.

However, in such a door that can be opened and closed by both sliding and swinging,
The purpose of this invention is to provide a door that rattles due to wind pressure, and the steady rest and lock pin that need to be removed with simple operation when opening and closing by swinging. It is something to do.

The present invention is a door that can be opened and closed by sliding and swinging, and it can also be opened by sliding by engaging the rail and fitting into the lock hole on the fixed side and the steady rest, which prevents the door from opening by sliding. If the door is equipped with a lock pin that prevents the door from opening even when the door is opened, an opening operation section consisting of a touch plate is provided on the indoor side of the door, and a connecting rod that rises when the opening operation section is pressed is placed inside the stile. The connecting rod is fixed to the steady rest, and is engaged with a long hole in the unlocking plate integrated with the lock pin, and is engaged with the rail and the lock hole, respectively, by pressing the opening operation part. By removing the steady rest and lock pin, it can be opened by swinging.

When the door is opened by swinging, the connecting rod is raised. As this continuous rod rises, the steady rest also rises. At this time, the unlocking plate of the lock is also rising, and the lock pin is also rising. At this point, when the door is pulled to return to the sliding opening/closing mode, the connecting rod descends and the steady rest descends.
Even if you lower the connecting rod, it will only go down inside the long hole.
It is not related to locking operation. Next, when the door is closed and locked, both the locking pin and the unlocking plate descend. Then, the lock pin fits into the lock hole of the rail and is locked. At this time, since it is a long hole, it is not related to the operation of the steady rest. Next, in an emergency or the like, when the touch plate is pressed, the connecting rod is pushed up. The steady rest then rises. Further, as the connecting rod rises, the unlocking plate rises, so the lock pin connected by the slider inside the lock also rises, and the rail is removed from the lock hole. If you forcefully push the door outside in this state, it will come off and swing.

Hereinafter, one embodiment of the present invention will be described based on the drawings from FIG. 4 onwards.

Next, a so-called Gremont lock 61 as shown in FIG. 10 is provided inside the frame 15. In this Gremont lock 61, an internal slider is moved up and down by a knob 62 on the indoor side and a key 63 on the outdoor side, and an unlocking plate 64 and a lock pin 65 connected to this slider are moved up and down. That is, when the lock pin 65 protrudes from below the lock 61, when it is lowered, it passes through the bearing 50 and is inserted into the lock hole 66 provided in the lower rail 47. Further, a connecting rod 67 is fixed upwardly to this lock pin 65, and at its upper end,
As shown in FIG. 11b, a link 69 is connected via a crank 68 that rotates around a shaft 70. This link 69 projects from a hole in a bearing 71 in the upper stile 16, and its tip faces the lower end of a lock pin 73 provided in the suspension frame 4 and urged downward by a spring 72. It is designed to be inserted into a lock hole 74 in the upper part of the hanging frame 4.
A power switch 75 is provided above the lock hole 74 to turn off the power to the automatic door when the door is locked.

The lock 61 has an unlocking plate 64 protruding from an internal slider, and an engagement rod 77 integral with the connecting rod 41 is loosely fitted into a long hole 76 of the unlocking plate 64.

Next, the operation of the opening/closing device according to the present invention will be explained.

Figures 10a and 10b show the door 5 being opened by swinging. In this state, the latch fitting 17 of the engaging portion 14 and the engaging plate 18 are not engaged, so the drive cam 23 is attracted by the spring 22,
It is in the state shown by the solid line in FIG. Also, due to the suction action of the spring 56, the triangular crank 54 is
is attracted, rotates around the first shaft 52, and the connecting rod 40 also rises. As the connecting rod 40 is raised, the link 33 is lowered via the link 38 at the upper end and the crank 36, and the cam 2 is lowered by the spring 28.
6 is tilted to the left in the figure and is in contact with the base end portion 25 of the drive cam 23. At the same time, the steady rest 42 at the lower end of the connecting rod 40 is also raised. At this time, the unlocking plate 64 of the lock 61 is also raised, the lower lock pin 65 is raised, and the upper lock pin 73 is lowered.

When the door 5 is pulled toward the hanging frame 4 in order to return to the sliding opening/closing state, the state shown in FIG. 11a is obtained. Then, the engagement plate 18 of the engagement portion 14 and the latch fitting 17 engage with each other, and at the same time, the drive cam plate 23 contacts the latch fitting 17 and rotates as shown by the chain line in FIG. 6 against the spring 22, and the cam The tip 27 of 26 moves to the right as shown in FIG. 11a. Along with this, the connecting rod 40 descends via the link 33 and the crank 36,
The steady rest 42 is lowered. At this time, steady rest 4
2 and the groove of the lower rail 47 do not match, and even if the door roller 48 touches the floor, the steady rest 42 will not move with the spring 4.
6, the lower rail 47
It will fit in the position that matches the groove. Also, 40 consecutive sticks
, the triangular crank 54 swings to the right in the figure, and the third shaft 59 engages with the notch 60. Further, as the connecting rod 40 descends, the engaging rod 77 also descends, but this only descends within the elongated hole 76 and is not related to the locking operation.

Next, when the door 5 is closed and locked, when the door is locked with the key 63 or the knob 62, both the lock pin 65 and the unlocking plate 64 are lowered, as shown in FIG. 12b. Then, the lock pin 65 fits into the lock hole 66 of the lower rail 47, and at the same time, the connecting rod 6
7 lowers the link 6 through the crank 68.
9 rises, pushes up the upper lock pin 73 against the spring 72, fits into the lock hole 74 and locks, and turns off the power switch 75.
At this time, the engagement rod 77 is loosely fitted into the elongated hole 76 and is not related to the operation of the steady rest 42.

Next, in an emergency, when the touch plate 41 is pushed as shown in FIG. 13a, the third shaft 59 engaged with the notch 60 of the integrated arm 51 is pushed out
A triangular crank 54 rotates about the fulcrum of the first shaft 52 and pushes up the connecting rod 40. Further, the connecting rod 40 is pushed up by the tension spring 56, and the triangular crank 54 remains in a rotated state, but only the touch plate 41 is returned to its original position by the spring 53. When the connecting rod 40 is pushed up, the steady rest 42 at the lower part rises, and the link 33 at the upper part also moves down via the crank 36. The shaft 34 of this link 33 is connected to the cam 26
Since it fits into the square hole 31 and is located at point B in FIG. 7, it descends through the vertical hole 30.
Further, as the connecting rod 40 rises, the unlocking plate 64 rises while being engaged with the engaging rod 77, so the lower lock pin 65 connected with the slider inside the lock 61 also rises, and the lower rail 65 is removed from the lock hole 66, and at the same time, the link 69 is also lowered by the rotation of the upper crank 68, and the upper lock pin 73 is released from the spring 72.
to remove it from the lock hole 74 and turn off the power switch 7.
5 turns on. When the door 5 is strongly pushed out of the room in this state, the door 5 is disengaged from the engaging portion 14 and swings around the swing fulcrum portion 10 shown in FIG. 1. Then, the drive cam 23 is disengaged from the latch fitting 17 and returned by the spring 22 as shown by the solid line in FIG. The tip 27 of the cam 26 is also returned to the left side in the figure by the spring 28, returning to the state shown in FIGS. 7 and 10a.

In addition, in the embodiment shown in FIG.
While it is engaged with the latch fitting 17, it is in the state shown by the chain line, but as shown in FIG. When this protrusion 78
It may also be arranged so that it comes off from the line and returns to the state shown by the solid line by the spring 22.

In the embodiment described above, the touch part 41 as the opening operation part is formed of a rectangular touch plate, and one of the vertical frames 1
5, but it is not limited to this; for example, it may be formed with a rod-shaped touch rod that spans between the left and right frames. Alternatively, it may be shaped like a small push button, usually covered with a thin transparent plate, and then broken and pushed in case of an emergency. moreover,
The opening operation section 41 is not limited to one that is operated by a pushing motion, but one that is operated by a pulling motion, one that is turned like a handle, one that is pulled up, one that is pulled down, one that pulls a string, one that is kicked with the foot, and one that is stepped on with the foot. , or something that hits you with your whole body.

Since the present invention is configured as described above, when the door is opened and closed by sliding or swinging, the steady rest engages with the fixed side when the door is normally closed, and the door is closed due to wind pressure, etc. It does not swing or deform, and when opened by swinging, the steady rest and lock pin are released from the fixed side by simply operating the opening operation part, allowing smooth opening and closing.
