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 an entrance portion and an exit portion having 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 Japanese Patent Application Laid-Open No. 2007-146548 (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.

JP 2007-146548 A

  In the above-described conventional device (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 provided. It is difficult to secure the property and 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 make the room removal) independent, and even if there are no visitors or exits, there is a practical difficulty such that if one is driven, the other must be driven in conjunction.

  In view of the above-described conventional circumstances, the present invention eliminates the inconvenience, enhances the windbreak effect while maintaining the safety of passers-by, and adopts an open / close system that suppresses the enlargement of the drive device as an automatic door, and is simplified. It is an object of the present invention to provide an opening / closing device for an entrance / exit having a great practical benefit.

  Such a switchgear according to the present invention is a switchgear provided by partitioning an entrance part and an exit part having a wind vent room at the entrance and exit of a building, wherein two or more winds are provided in the entrance part and / or the exit part. It is characterized by disposing adjacent chambers and opening and closing swing-type automatic doors on the indoor side and the outdoor side of each wind chamber and interlocking the opening and closing operation of the internal and external automatic doors. To do. In other words, instead of the door opening / closing method of the automatic door as a circulation movement method as in Patent Document 1, a swing method that can reduce the installation front width from among general automatic door opening / closing methods, for example, Interlock control is adopted in order to provide a windshield function as well as adopting a hinged door, a folding door, a rotating slide, and the like, and a double door type thereof.

The automatic doors that are interlock controlled on the indoor side and the outdoor side of the windbreak room are used at the entrance / exit of the clean room, but they are generally a sliding method in which the door plate moves only to the side slide. In addition, it is possible to enter and exit from both inside and outside of the windbreak chamber, and the frequency of opening and closing the inside and outside automatic doors is not so high.
In the case where the entrance and exit are divided and arranged at the entrance and exit of the building as in the present invention, it is generally necessary to cope with the case where there are many visitors and exits, so the entrance and exit Two or more windbreak chambers are arranged adjacent to one or both of them so that an entrance or exit person can select and pass through the open windbreak room side.
And, in order to maintain a large amount of traffic in the entrance part or the exit part, it is necessary for an attendant or an exit person to ensure that at least one of the automatic doors can be opened with no or minimum waiting time, For this purpose, control is performed in association with the opening / closing timings of the automatic doors of adjacent wind vent rooms, that is, a control method as exemplified in the embodiments described later is adopted.

Furthermore, in order to secure mass traffic for the entrance and exit persons, it is preferable to always open and close the automatic door of the entrance or exit part, so that the windbreak function of the building is less affected. Depending on the situation, for example, the season of spring and autumn or the temperature difference between the inside and outside of the building, the interlock control may be canceled or either the inside or outside door may be opened.
In the present invention, it is not always necessary to arrange the entrance part and the exit part side by side, and it is also possible to arrange each in a separate area, but the entrance part and the exit part are close to each other. In the side-by-side configuration, the number of passages on the entry / exit side may be increased or decreased by changing the direction of entry / exit according to the time of day or the number of people entering / exiting, thereby maintaining mass traffic. Is possible.

  According to the present invention, the automatic doors arranged on both the inside and outside of each wind removal chamber are of a stationary opening and closing method and a swing method, so that safety can be ensured compared with a revolving door and a normal opening and closing drive device is adopted. Thus, an entrance / exit device having a simple structure can be provided, and the opening / closing operation of the inner / outer automatic door is interlock-controlled, so that the windshield effect at the entrance / exit can be ensured.

  In addition, since each entrance or exit portion has two or more windbreak chambers arranged adjacent to each other, it is possible to select and pass the windbreak chamber side on which the visitors or exiters are open. In addition, control is performed in association with the opening / closing timing of the automatic doors of adjacent windbreak rooms, or the interlock control is released in a timely manner according to the entrance / exit conditions, and the number of passages in the entrance and exit sections is increased or decreased. According to this, it is possible to maintain mass traffic of visitors or exits. Therefore, it is excellent in terms of construction and use, and practical benefits can be improved.

The embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional plan view showing an outline of a doorway 1 of a building, and FIG. 2 is a front view seen from the outside.
As shown in FIG. 1, the doorway 1 is formed with wind removal chambers 3 a, 3 b, 4 a, 4 b having a rectangular shape in plan view, which are partitioned by side walls 2, 2,...
In the windbreak room, the windbreak rooms 3a and 3b are used as entrance windbreak rooms, that is, entrances (entrance passages) where visitors try to enter the building, and the windbreak rooms 4a and 4b are used as exit windbreaks. It is a one-way passage which is a room, that is, an exit portion (exit passage) where an exit person goes out.

The windbreak chambers 3a, 3b, 4a, 4b are installed on the indoor side and the outdoor side so that the automatic doors can be opened and closed. Specifically, automatic doors 11 and 13 are installed on the entrance side (outside of the entrance) of the entrance wind removal chambers 3a and 3b, and automatic doors 12 and 14 are installed on the exit (interior side) of the exit wind removal chamber 3a and 3b. Automatic doors 15 and 17 are installed on the entrance side (inside the room) of 4a and 4b, and automatic doors 16 and 18 are installed on the exit side (inside the room).
The side walls 2 that partition the windbreak chambers 3a, 3b, 4a, and 4b use high-strength partition wall plates as the side walls 2 'for installing the automatic doors. Is installed (see FIG. 2), and an automatic door drive device (not shown) is mounted in the joint 21 thereof.
The side walls 2 other than the side wall 2 'are preferably made of a glass material or a transparent plastic material so that the inside of the adjacent windbreak chambers 3a, 3b, 4a and 4b can be seen through.

  The automatic doors 11 to 18 are well-known doors that control the opening and closing of the door plates 10 by driving a driving device in the eyeless 21 by detection of a start sensor (not shown) such as a mat switch or a light switch. A swing method is employed as the door plate 10 opening and closing method. Specifically, in FIG. 1, a rotating slide, which is one of the swing methods, that is, the door plate 10 slides toward the side wall 2 ′ while rotating in the opening direction by approximately 90 degrees, and is fully opened substantially parallel to the side wall 2 ′. The following types are illustrated.

  And the automatic doors 11-18 make the automatic doors 11 and 12, 13 and 14, 15 and 16, and 17 and 18 for each windbreak chambers 3a, 3b, 4a and 4b, respectively. Control interlock. That is, each set of automatic doors 11 and 12, 13 and 14, 15 and 16, 17 and 18 is controlled so that when either the entrance or exit door plate 10 is open, the other is not opened. The windshield effect is secured without opening the two door plates of each windshield room at the same time.

Thus, the entry / exit from the entrance / exit 1 will be described with reference to FIG. 1. When the entrance sensor detects the entrance P approaching the entrance-side automatic door 11 of the entrance windbreak chamber 3a, the door of the automatic door 11 is detected. Since the board 10 is opened, the visitor P can enter the windbreak room 3a.
The visitor P who has entered the entrance windbreak room 3b can enter the building when the door plate 10 of the door 14 is opened by approaching the exit automatic door 14, during which the wind When a visitor P approaches the entrance side automatic door 13 of the removal room 3b, the entrance side automatic door 11 can still enter the wind removal room 3a when the entrance side automatic door 11 is still open, but the automatic door 11 is closed. Waits until the automatic door 14 is closed, and when the door 14 is closed, the entrance-side automatic door 13 is opened, so that it is possible to enter the wind removal chamber 3b, and thereafter the wind removal chamber is the same as described above. You can enter the building from the exit of 3b.
On the other hand, in the case where the exit person Q leaves the exit windbreak chamber 4a or 4b, either the windbreak chamber 4a or 4b is used as in the case of the entry windbreak chamber except that the passage direction is reversed. You can enter the room through the automatic door that opens, and exit from the building.

  Therefore, the entrance automatic doors 11, 13, 15, 17 and the exit automatic doors 12, 14, 16, 18 are interlocked in the windbreak chambers 3 a, 3 b, 4 a, 4 b for both the entrance and exit passages. The windshield function can be secured by the control, and both the entrance and exit routes are equipped with two entrance automatic doors that can be opened and closed in a timely manner. The exit can be passed repeatedly effectively. Furthermore, it is possible to reduce congestion of visitors or exits by adding three or more windbreak rooms for entry and exit.

Then, when the waiting time for the automatic door opening of the visitors or exits is long due to the interlock control, the following control is further performed. Since the entrance windbreak chamber and the exit windbreak chamber can be controlled by the same method, only the entrance windbreak chambers 3a and 3b are illustrated and described for convenience of explanation (FIG. 3, FIG. 4).
FIG. 3 shows that the entrance automatic door of the other windbreak chamber can be opened from the time when the entrance automatic door of the one windbreak chamber starts the closing operation. Specifically, as illustrated in FIG. 1, the entrance-side automatic door 11 of the windbreak chamber 3a is opened and the visitor P enters the windbreak chamber 3a. After the door is fully opened, as shown in FIG. When the entry-side automatic door 11 performs the closing operation, the other entry-side automatic door 13 is opened from the time when the closing operation is started.
Note that “to allow opening operation” refers to confirming the output of the closing completion signal of the exit automatic door 14, outputting the opening activation signal of the entrance automatic door 13, and opening the door plate 10 of the door 13. That is.

Therefore, even when there is no person in front of the entrance automatic door 13, the door plate 10 of the automatic door 13 is opened as long as the exit automatic door 14 is fully closed. P can also notice the opening of the automatic door 13 and turn to the door 13 side, that is, the wind removal chamber 3b. After that, as shown in FIG. 4, in the windbreak room 3a, the visitor P who entered the room enters the building by opening the exit side automatic door 12, and in the windbreak room 3b, the visitor P who has turned there While entering the room, further subsequent visitors P can enter the windbreak room 3b.
In the above description, the case where the entry-side automatic door 11 performs the closing operation has been described. However, when the entry-side automatic door 13 activates the closing operation, the other entry-side automatic door 11 can be opened. The same applies to the case.

Alternatively, a control method may be employed in which the entrance automatic door of the other windbreak chamber can be opened and operated after a predetermined timing after the entrance automatic door of one windbreak chamber is fully opened.
For example, in FIG. 1, the entrance-side automatic door 11 of the wind removal chamber 3a is fully opened, but the entrance-side automatic door 13 of the wind removal chamber 3b is not opened after a certain time from that time. As long as it is open. According to this, since the door plate 10 of the entrance side automatic door 13 is opened, it is possible to guide the visitors to the windbreak chamber 3b side, so that the flow of visitors to the windbreak chamber 3a is suppressed and the entrance side automatic is controlled. The start of the closing operation of the door 11 can be accelerated, in other words, the closing of the entry-side automatic door 11 can accelerate the opening of the exit-side automatic door 12 to facilitate the passage in the windbreak chamber 3a. .

Furthermore, as another control method, the entrance automatic door of one windbreak chamber and the exit automatic door of the other windbreak chamber are synchronized.
Specifically, on the entrance side, as shown in FIG. 1, the entrance automatic door 11 of the wind removal chamber 3a and the exit automatic door 14 of the wind removal chamber 3b are connected to the entrance automatic door 13 of the wind removal chamber 3b. For example, when the exit automatic door 14 starts the closing operation, the entrance automatic door 11 also starts the closing operation, and the entrance automatic door 11 opens. When starting up, the automatic door 14 is opened to start the operation.

And in addition to the above control, a voice guide that guides the opening and closing operation of the automatic doors 11-18, for example, "the door will open soon", "the door will close soon", "please wait" for each automatic door Make a sound such as “Turn to the next entrance (exit)” in a timely manner.
Further, a signal 20 is displayed on the entrance side of each wind chamber 3a, 3b, 4a, 4b so that the possibility of entering the room can be seen from a position slightly away. Specifically, an “×” or a character meaning no admission, such as an “◎” symbol or a character meaning admission to an easy-to-see part of the automatic doors 11, 13, 16, 18 on the entry side, for example, the invisible 21. Etc. are displayed according to the state of each door (see FIG. 2).
As a result, it is possible to prevent the confusion of visitors and exits and enable smooth traffic.

Next, another embodiment will be described. The interlock control is a method for ensuring a windbreak effect in a building. Therefore, the interlock control is not necessarily required in the spring or autumn season, or in a period when the temperature is relatively warm and there is no difference between the internal and external temperatures and the windshield function is not required.
For this purpose, temperature measuring devices are provided at appropriate locations inside and outside the windbreak chambers 3a, 3b, 4a, 4b, and the interlock control may be canceled if the temperature difference is a small difference within a predetermined value. Good.
Alternatively, when the interlock control is released, it is possible to open the door plates 10 of either the internal or external automatic doors, preferably the automatic doors 12, 14, 15 and 17 in a fully opened state in order to ensure smooth traffic. Is preferable.

Moreover, in the form in which the entrance windbreak chambers 3a, 3b and the exit windbreak chambers 4a, 4b are arranged in parallel as described above, the number of windbreak chambers for entry and exit may be increased or decreased.
For example, in a time zone with a large number of visitors, the windbreak room 4a is changed to entry, the number of entry windbreaks is three, the number of exit windbreaks is one, and the number of exits is In many time zones, the wind venting chamber 3a is changed to an exit route, the number of exit wind vent chambers is set to three passages, the number of entrance wind vent chambers is set to one passage, and the like. Then, in order to measure the number of visitors and exits, an entrance / exit management device is installed at the entrance side position of the entrance windbreak room and the exit side position of the exit windbreak room, and the measured value The control is appropriately changed according to the above.

  In order to operate the various controls described above, it is executed by a control device connected to an automatic door driving device or controller, a voice guidance device, a signal indicator, a temperature measuring device, an entrance / exit management device, or the like.

In the above-described embodiment, the rotary slide door is exemplified as the swing method of the automatic door. Instead, for example, a swing door or a folding door is adopted, or a double swing type of the rotary slide, the swing door, and the folding door is adopted. It is also possible to employ this, and FIG. 5 shows a case where a hinged door is used as an example. In addition, since it is the same even if it installs in said any as a windshield room, the case where a hinged door is installed in the windshield room 3a is shown in order to simplify illustration description.
FIG. 5 (1) shows that the door plate 30 is rotated approximately 90 degrees by a single-open type door to the entrance-side automatic door 31 and the exit-side automatic door 32, that is, by a one-point support shaft disposed near one side wall 2 ′. It is a door that opens and closes the windbreak chamber 3a.
FIG. 5 (2) employs a double-opening type consisting of two door plates 40, 40, which is another type of the opening-side automatic door 41 and the outgoing-side automatic door 42, which is the above-described opening type.
When using these hinged door types, the door plate 30 or 40 can be freely opened and closed at the entrance edge of the side wall 2 'on the entrance side of each windbreak room. It is easy to judge the open / close state of the automatic door of the windbreak room next to it. This also applies to the case where the folding door type is adopted.

Moreover, in the above-mentioned embodiment, although the case where the windbreak chambers 3a, 3b for entrance and the windbreak chambers 4a, 4b for exit were arranged in close proximity to each other was illustrated, instead of the windbreak chambers 3a, It is also possible to arrange 3b and 4a, 4b in remote areas within the building.
Furthermore, the case where two windbreak rooms for entry and two windbreak rooms for exit are formed, but for buildings with a large number of visitors, it is optional to add three or more rooms. It is.

It is a cross-sectional top view which shows the outline | summary of the opening / closing apparatus of this invention entrance / exit.
