Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a door opening/closing device, and more specifically, a door opening/closing device that combines and fits a manually operated swinging door and another sliding door into one opening frame. When the swinging door is opened, the sliding door is also opened in conjunction with the sliding door, so that when used as an entrance to a hospital, for example, even patients in wheelchairs or physically disabled people can easily enter and exit.

[Conventional technology]

In order for this type of wheelchair to pass through, the doorway must open wide to the left and right. Therefore, conventional entrances and exits are generally opened and closed using manually operated double doors.

[Problem to be solved by the invention]

However, with manual double doors, whether you push them open or pull them open, the range of movement on the vehicle is restricted when a wheelchair user tries to get in or out. It is difficult to open both at the same time. Therefore, it was difficult for a wheelchair to pass by just opening one side of the door, and in the end it was not easy to get in and out on your own.

Therefore, an object of the present invention is to fit a combination of two types of doors, a swinging door and a sliding door, into one opening frame, so that when one of the swinging doors is opened, the other sliding door also opens at the same time. To provide a door opening/closing device which allows easy entry and exit even in a wheelchair.

[Means to solve the problem]

As shown in the figure, the door opening/closing device of the present invention includes a swinging door 2 and a sliding door 3 fitted side by side in one opening frame 1; It should be hooked into the side and be able to be opened and closed in the front and rear directions around this fishing base side.
The sliding door 3 is supported so as to be slidable in the left-right direction with respect to the opening frame 1, and has an opening position in which it enters a door pocket 21 provided on the other side of the opening frame 1 in the left-right direction, and a door pocket 2
Chain sprockets 10, 10 are arranged on the left and right inside the upper frame 7 of the opening frame 1, and the chain 11 is wound between the chain sprockets 10, 10. The upper end of the sliding door 3 is connected to one side 11a of the chain 11, and the tip of the guide arm 13, which is incorporated in the upper frame 7 so as to be slidable in the left and right direction, is connected to the other side 11b of the chain 11. The opening/closing arm 16 is located at the upper end of the swinging door 2.
The base end of the guide arm 13 and the extending tip of the opening/closing arm 16 are supported by the shaft 15.
It is required to be pivotally connected via 7.

[Effect]

The sliding door 3 is supported so as to be slidable in the left-right direction with respect to the opening frame 1, and is connected to one side 11a of the chain 11. The swing door 2 can be opened and closed in the front and rear directions, and has an opening/closing arm 16 and a guide arm 1.
3 to the other side 11b of the chain 11.

Therefore, when the swinging door 2 is operated to open, the chain 11 runs in one direction, and the running of the chain 11 causes the sliding door 3 to open in the direction of entering the door pocket 21, and the swinging door 2 and the sliding door 3 and open at the same time. In other words, the entrance/exit of the opening frame 1 can be widened at the same time by opening one of the swinging doors 2 and the other sliding door 3 as well.

Conversely, when the swinging door 2 is closed, the sliding door 3 is also automatically pulled out from the door pocket 21 to close the entrance/exit of the opening frame 1.

〔Example〕

In FIG. 1, reference numeral 1 denotes an opening frame for an entrance/exit of a building, and a swinging door 2 and a sliding door 3 are fitted into the opening frame 1 side by side.

The swing door 2 is hooked into the left side of the opening frame 1 in the figure, and can be opened and closed in the front and rear directions around a pivot 4 (or hinge) on the base side.

The sliding door 3 supports a hanging roller 6, which is attached with hanger brackets 5 on the left and right sides of its upper end, so as to be able to move freely in the left and right direction with respect to the lower rear rail 7a in the upper frame 7 of the opening frame 1. Guide rollers 8, 8 fixed on the left and right sides are slidable into grooves in a lower frame 9 of the opening frame 1. Thus, the sliding door 3 can be opened and closed by sliding in the left and right directions along the upper and lower frames 7 and 9 of the opening frame 1 in conjunction with the opening and closing of the swing door 2.

To explain a specific example of the opening/closing interlocking mechanism between the swinging door 2 and the sliding door 3, as shown in FIG.
0, and an endless chain 11 is wound between the sprockets 10, 10 in parallel in the front and back.

A sliding door 3 is attached to a part of the front side 11a of the chain 11 as shown in FIGS. 2 and 3.
The upper end 12a of the front gate-shaped chain bracket 12 fixed to the upper end is connected. On the other hand, a Z-shaped guide arm 13 is built into the upper frame 7 so as to be slidable in the left-right direction, and the tip of the guide arm 13 is connected to a part of the rear other side 11b of the chain 11 as shown in FIG. They are connected using brackets 14.

The base end of an opening/closing arm 16 is horizontally attached to the upper end of the swinging door 2 via a vertical shaft 15, and the extending tip of the opening/closing arm 16 and the base end of the guide arm 13 are connected to each other by a pivot 17. Pivotally connected through.

The tip of the guide arm 13 is equipped with a guide roller 18 that slides on the upper rail 7b in the upper frame 7, as shown in FIG. Guide roller 19 sliding into the groove of lower rail 7c of frame 7
These allow the guide arm 13 to slide easily and smoothly in the left and right direction within the upper frame 7.

A steady rest roller 20 is also installed inside the chain bracket 12 at the upper end of the sliding door 3, as shown in FIG.
By sliding and guiding the chain 11 into the groove of the lower rail 7c of the upper frame 7, the chain 11 is prevented from swaying in the longitudinal direction.

Now, as shown in FIGS. 5 and 6, if the swing door 2 is opened in one direction, front and back, centering on the pivot 4, the guide arm 13 will move upward in the figure due to the pulling action of the opening/closing arm 16 integrated with this. The chain 11 is moved in the left direction within the frame 7 to run in the direction of the arrow. As the chain 11 runs, the sliding door 3 opens and moves in the direction of entering a door pocket 21 provided on the right side of the opening frame 1. In other words, when the swinging door 2 is opened, the sliding door 3 will automatically open and the swinging door 2 will open.
The doorway of the opening frame 1 opens wider than the door width,
This makes it easier for people in wheelchairs to get in and out.

Conversely, when you close the opening door 2, the opening/closing arm 1
6 moves the guide arm 13 in the opposite right direction, and the chain 11 runs in the direction opposite to the direction of the arrow, and as a result of this running, the sliding door 3 is automatically closed.

[Another example]

Although the illustrated example is as described above, the present invention is not limited thereto. For example, swing door 2
It is also possible to attach an automatic closer of a known structure to the door so that the swinging door 2 automatically closes, and in conjunction with this, the sliding door 3 automatically closes.

[Effects of the Invention] As explained above, the present invention combines a swinging door 2 and a sliding door 3, and when one swinging door 2 is opened/closed, the other sliding door 3 automatically opens and closes. did. Therefore, it is convenient for people in wheelchairs and people with physical disabilities to enter and exit, and is particularly advantageous as a semi-automatic door for entrances and exits of buildings such as hospitals.

As an interlocking mechanism for opening and closing the swing door 2 and the sliding door 3,
Since the left and right sprockets 10, 10 arranged in the upper frame 7 of the opening frame 1 and the chain 11 wound between both sprockets 10, 10 are used,
No slip occurs between each sprocket 10 and the chain 11. Therefore, for example, when the swinging door 2 is fully opened, the sliding door 3 does not remain in a half-open state. It has the advantage of ensuring that the
