Description

  The present invention relates to an opening / closing device constructed at the entrance of a building such as a hotel, department store, or hospital, and more specifically, at the entrance of a building in order to provide a windbreak function for preventing cold air or warm air from entering the building. The present invention relates to an opening / closing device for an entrance / exit provided by partitioning a windbreak chamber.

Conventionally, a revolving door has been permanently installed as an opening / closing device for an entrance / exit with an effective windbreak function, but recently it is difficult to ensure safety, such as being unable to stop the rotating door plate in an emergency, so recently it is difficult to ensure safety. A switchgear as disclosed in Patent Document 1 has been proposed.
Specifically, a plurality of flat panels (door plates) that block the inlet passage (entrance wind passage chamber) and the outlet passage (exit wind passage chamber) are each slid in parallel along each passage and each passage It is a device that horizontally slides from one passage to the other at the end, that is, a device that circulates and moves the door plate in a square shape between the entrance passage and the exit passage.
In addition, sliding automatic doors are installed at the indoor and outdoor ends of two adjacent windbreak chambers, and opening and closing operations are controlled by interlocking between the internal and external automatic doors of the adjacent windbreak chambers. An apparatus is disclosed in US Pat.

JP 2007-146548 A JP 2009-127205 A

In the above-mentioned Patent Document 1, since the door plate that blocks the entrance passage and the exit passage in a partition shape moves along each passage, airtightness between the edge of the door plate and the side wall of the passage is ensured. There is a risk that the windbreak effect may be reduced. In addition, because the door plate is moved in a square circulation between both passages, the drive device as an automatic door becomes large, which causes construction difficulties and is accompanied by an entrance passage (entrance wind removal chamber) and an exit passage (outlet passage wind). It is difficult to separate the room), and even if there are no visitors or exits, there is a practical problem such that if one is driven, it is necessary to drive the other in conjunction.
On the other hand, in Patent Document 2, since the sliding automatic door is adopted, there is no problem as in Patent Document 1, but since the door plate is arranged for each wind chamber, each wind chamber has a structure. The width of the opening is narrowed to about half of the frontage, which not only causes congestion during times when there are many visitors, but also makes it difficult to access the wheelchair. In order to solve this problem, in order to secure an opening width substantially corresponding to the entrance of the windbreak chamber, the door plate to be moved must be moved to the outside of the windbreak chamber. There is a drawback that requires dead space.

  In order to eliminate the above-mentioned conventional problems, the present invention adopts a sliding automatic door that is widely used to make the opening / closing system that suppresses the enlargement of the driving device, while maintaining the wind removal function. It is an object of the present invention to provide an opening / closing device for an entrance / exit that can avoid congestion of visitors by using an automatic door arrangement structure that can ensure a wide opening width.

In the basic mode of the door opening and closing device according to the present invention, a windbreak room having a pair of two rooms is arranged adjacent to a building entrance and exit, and one door plate is provided at each of the entrance end and the exit end. A sliding type automatic door that can move between the windbreak chambers is arranged, and one or two partitioning sections are formed between the inlet end and the outlet end that cross the windbreak chambers. A sliding type automatic door that can move each door plate between the windbreak chambers is also provided in each partition portion. Then, one or two linkage groups that alternately open and close at a predetermined timing are selected from the automatic doors. In addition, the entrance end and the exit end are in a standby state in which one of the windbreak chambers is opened and the other is closed. When a passerby is detected from the standby state, the opening and closing operations of the automatic doors that are linked with each windbreak chamber are linked by holding at least one door plate with the door closed. The open / close position is reversed, and the windbreak chambers are alternately opened and closed by repetitive control .
That is, according to the present invention, a sliding type automatic door that can move each door plate between the two wind venting chambers is provided at each inlet end and outlet end of the two adjacent wind venting chambers and the partition part. That one of the two adjacent entrance ends is open, the other is closed, and adjacent to each other. At the exit end, the open / closed state is opposite to the entrance end, and for each windbreak chamber, the linked automatic door opens and closes while at least one unselected door plate closes the windbreak chamber It is characterized by reversing the open / closed positions of the inlet end and the outlet end by operating.

Since the partition part is arranged at the entrance end and the exit end, if the number of places increases, not only will the number of automatic doors increase, but the depth of the windbreak room becomes too long and becomes impractical, so one place or Two places.
In the embodiment with one partition part, it is formed between the inlet end and the outlet end of the windbreak chamber, and the automatic doors are arranged in three units, and the linkage assembly inevitably has the inlet end and the outlet. Automatic door with end is selected. Then, the door plate at the inlet end or the outlet end is linked so as to alternately move to the other wind vent chamber side. One door plate at the inlet end or the outlet end starts moving first, and after the movement is completed, the other door plate starts moving, and after the movement is completed, the door plate of the automatic door at the partitioning part moves. Is controlled to start .

In addition, when there are two partition parts, the two parts are formed at equal intervals between the inlet end and the outlet end of the windbreak chamber, and there are four automatic doors arranged respectively. Two sets of the linkage sets are selected. Specifically, the linkage assembly selects an automatic door with a partition portion close to the inlet end and the outlet end as the linkage set, and an automatic door with a partition portion far from the inlet end and the outlet end, respectively. There is a mode to select.
And in any aspect, each set of automatic doors is linked to move simultaneously in the relative direction, and the two sets of automatic doors are controlled to prohibit starting until one set completes movement. It is.

Each automatic door has a well-known start sensor such as a mat switch, a light sensor or a photoelectric sensor installed near the door plate on one side, that is, the front side of the linkage, and a passerby is detected by the sensor. The door plate is opened by outputting a start signal to one or both of the automatic doors, and a known auxiliary sensor (safety sensor) is installed in the movement range of the door plate. It is preferable that the door plate is temporarily stopped when the human body is detected.
Furthermore, it is preferable to arrange signals (for example, “◎” and “x”) indicating whether or not entry is possible at the entrance end and the exit end of each wind removal chamber.

According to the present invention, in a mode in which there is one partition part, that is, one set of linkage set, a passerby from the entrance end of the open wind vent chamber (referred to as the first wind vent chamber for convenience) in the standby state. Enters the exit door plate and approaches the door plate at the outlet end, and is detected by the activation sensor, the second wind vent chamber remains with the door plate at the partition portion stopped in the other wind vent chamber (referred to as a second wind vent chamber for convenience). The automatic doors at the inlet end of the first windshield and the outlet end of the first windbreak chamber are opened and closed by an interlock control system. That is, the door plate at the inlet end of the second wind vent chamber in which the door plate of the partition part is closed moves to the first wind vent chamber, and the movement is completed (the inlet end of the first wind vent chamber is closed, Control is performed so that the door plate at the outlet end of the first wind chamber moves to open the outlet end of the same wind chamber after the inlet end of the two wind chamber is opened. Accordingly, a passerby who has reached the outlet end of the first wind vent room can leave the same wind vent room, and on the other hand, from the opened entrance end of the second wind vent room, a new one enters the same wind vent room. Passers can enter the room.
Then, after the opening / closing operation by the interlock control is completed, the door plate of the partition part starts to move from the second wind vent chamber to the first wind vent chamber, and the passerby who enters the second wind vent chamber by the movement exits As the passer approaches the door plate at the exit end, the entrance door and the automatic door at the exit end are interlock controlled as described above (however, the door plate that moves first is opposite) ) The same operation can be repeated to leave the exit end.

On the other hand, in a mode in which there are two partition parts, that is, two linked groups, a passerby enters from the entrance end of the open wind vent chamber (referred to as the first wind vent chamber for convenience) in the standby state. Of the other wind vent chamber (referred to as the second wind vent chamber for convenience) and the partition portion of the first wind vent chamber that is linked to it. The automatic door is opened and closed by the simultaneous interlock control method.
That is, the door plate at the entrance end of the second wind vent chamber starts to move to the first wind vent chamber and starts to open the entrance end, and at the same time, the door plate at the partitioning portion of the first wind vent chamber becomes the second wind vent chamber. Control to complete the movement. Thereby, the inlet end of the first wind chamber is closed and the partition portion is opened, and the inlet end of the second wind chamber is opened. Meanwhile, since the automatic doors of the other linkage group are prohibited from starting, the closed state of each windbreak chamber is maintained. Therefore, a passerby who has entered the first windbreak chamber can proceed to the exit end, and a new passerby can enter from the entrance end of the second windbreak chamber.
When a passerby that reaches the exit end of the first wind removal chamber is detected by the activation sensor, the other linked automatic doors are similarly opened and closed by the simultaneous interlocking control method. Passers of the room can exit from the exit end, and when the passer-by entering the second windbreak room approaches the door plate of the partition part and is detected by the activation sensor, the direction of movement of the door is opposite. By repeating the same operation as described above, the passerby of the second windbreak chamber can also leave the exit end.

  According to the present invention, since the automatic door of the entrance end, the exit end and the partition part of the windbreak chamber is a slide type in which each one door plate is movable between the windbreak chambers, A widely used sliding automatic door drive device can be used to avoid an increase in size of the drive device, and the inlet and outlet ends of the windbreak chamber correspond to the entrance of the windbreak chamber. The opening width can be secured, and congestion of visitors can be avoided.
