JP7650693B2 - Drive system for automatic door device, and automatic door device - Google Patents

Description

The present invention relates to a drive system for an automatic door device, and an automatic door device.

Conventionally, a system has been proposed for moving the opening and closing of an automatic door device installed in an opening in a wall of a building. Such a system includes, for example, a driving pulley and a driven pulley that are installed at a distance from each other along the opening and closing direction of the opening and closing body inside the blind, a circular toothed belt wound around the driving pulley and the driven pulley, a connector that connects the toothed belt to the opening and closing body, and a motor that moves the opening and closing body opening and closing as the toothed belt rotates by rotating the driving pulley (see, for example, Patent Document 1). In addition, the distance between the driving pulley and the driven pulley is set longer than the movement stroke that the opening and closing body can move open and closed, and the width of the inspection hatch formed in the blind is set to be approximately the same length as the width of the blind in which the driving pulley and the driven pulley are housed.

JP 2013-234567 A

Here, depending on the conditions around the opening, it is conceivable that the width of the inspection hatch may only be set to a length shorter than the width of the blind (for example, approximately the same as the effective opening width of the opening). However, in the above conventional system, as described above, the distance between the driving pulley and the driven pulley is set to be longer than the above-mentioned movement stroke. For example, if the width of the inspection hatch is shortened while maintaining the distance between the driving pulley and the driven pulley, it becomes difficult to inspect the above conventional system through the inspection hatch, and there is a risk that it may become difficult to ensure the maintainability of the above conventional system.

Furthermore, when the distance between the driving pulley and the driven pulley is shortened and the width of the inspection hatch is shortened, in order to prevent the driving pulley located on the closing side from coming into contact with the connector when the opening is fully closed by the opening/closing body, the connector is attached to the opening/closing body so that it is located on the opening side of the driving pulley when the opening is fully closed. As a result, when the opening is fully opened by the opening/closing body, the part from the door-end end of the opening/closing body to the connector located on the closing side is located inside the opening (i.e., it is left behind), so the left-behind dimension of the opening is set relatively large and the effective opening width of the opening is shortened, which could make it difficult to ensure passage through the opening.

On the other hand, in order to avoid the above-mentioned problems, it is also possible to use a linear engine instead of the conventional system described above, and to open and close the opening and closing body connected by the slider of the linear engine. However, since linear engines are very expensive, there is a risk that the installation costs of the system will be excessive.

For these reasons, there was room for improvement in terms of the system's maintainability and installation costs, as well as the ease of passage through the openings.

The present invention is intended to solve the problems in the conventional technology described above, and aims to provide a drive system for an automatic door device, and an automatic door device, which can reduce the installation costs of the drive system, ensure the maintainability of the drive system, and ensure the passage through the opening.

Therefore, even if the drive system is configured using conventional members (specifically, the first pulley means, the second pulley means, and the drive means), the size of the inspection opening for inspecting the above members can be reduced, and the maintainability of the drive system can be ensured while suppressing the installation cost of the drive system. In addition, the remaining dimension of the opening can be avoided from becoming large, making it easier to ensure the passage of the opening.
In addition, the first pulley means and the second pulley means are arranged so that the axial directions of the respective rotating shafts of the first pulley means and the second pulley means are approximately identical to each other and the first pulley means and the second pulley means are positioned at different positions from each other in the axial direction. This makes it easier to avoid the first pulley means and the second pulley means coming into contact with the first connecting means or the second connecting means during the opening and closing movement of the opening and closing body, and ensures the length of the movement stroke of the opening and closing body.

According to the drive system for an automatic door device described in claim 2, the first pulley means, the second pulley means, the first connection means, and the second connection means are arranged so that in the fully closed state, either the first connection means or the second connection means is located closer to the closing direction of the opening than the first pulley means and the second pulley means, and/or in the fully open state, the other of the first connection means or the second connection means is located closer to the opening direction of the opening than the first pulley means and the second pulley means, so that the length of the first interval can be reliably shortened and the size of the inspection hatch can be reliably reduced.

According to the drive system for an automatic door device described in claim 3, the traction means is arranged so that it passes through the first connection means, the first pulley means, the second pulley means, and the second connection means in order, winding around the first pulley means and the second pulley means, so that the length of the first interval can be reliably shortened, and the size of the inspection hatch can be reliably reduced.

According to the drive system for an automatic door device described in claim 4, the length of the second interval is longer than the length of the first interval, so the length of the stroke of the opening and closing body can be longer than when the length of the second interval is shorter than the length of the first interval, making it easier to reduce the size of the inspection hatch.

According to the drive system for an automatic door device described in claim 5, the first pulley means and second pulley means are positioned in a position corresponding to the opening and closing body in the fully closed state. Therefore, if the automatic door device is a type that is fitted into a door pocket board, the first pulley means and second pulley means can be located in a maintainable position regardless of the open/closed state of the opening and closing body, making it easier to ensure the maintainability of the drive system.

According to the drive system for an automatic door device of claim 6, the drive system includes a second pulley means provided at a first interval from the first pulley means substantially along the opening/closing direction, a drive means for rotating the first pulley means, a first connection means and a second connection means connected to the opening/closing body, the first connection means and the second connection means provided at a second interval from each other substantially along the opening/closing direction, and a pulling means for pulling the opening/closing body substantially along the opening/closing direction as the first pulley means and the second pulley means rotate, The towing means has one end connected to the first connecting means and the other end connected to the second connecting means, and the first pulley means, the second pulley means, the first connecting means, and the second connecting means are arranged so that the length of the movement stroke of the opening/closing body towed by the towing means is longer than the length of the first interval, so that the length of the first interval can be shortened compared to the conventional technology (a technology in which the opening/closing body is moved to open and close with the rotation of a ring-shaped toothed belt wound around a driving pulley and a driven pulley). Therefore, even if the drive system is configured using conventional members (specifically, the first pulley means, the second pulley means, and the drive means), the size of the inspection opening for inspecting the above members can be reduced, and the maintainability of the drive system can be ensured while suppressing the installation cost of the drive system. In addition, the remaining dimension of the opening can be avoided from becoming large, making it easier to ensure the passage of the opening.

First, [I] the basic concept of the embodiment is explained, then [II] the specific content of the embodiment is explained, and finally, [III] modified examples of the embodiment are explained. However, the present invention is not limited to the embodiment.

[I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment generally relates to an automatic door system that is provided at an opening of a building and that slides the opening/closing body that opens and closes the opening substantially along the opening/closing direction, and to the automatic door system itself.

The term "building" as used herein can refer to any specific structure or type, but is a concept that includes, for example, commercial facilities, office buildings, public facilities, and housing complexes such as apartments and condominiums, but in the embodiment, it will be described as a commercial facility.

In addition, an "opening in a building" is an opening formed in a part of the structure of a building (e.g., a wall, ceiling, or floor) for the purpose of installing a window or entrance.

In addition, "opening and closing body" refers to a structure that restricts or limits entry and exit through an opening in a building, and is a concept that includes, for example, opening and closing bodies for automatic door systems.

The opening and closing structure of the opening and closing body is arbitrary, and can be configured as, for example, a single-sliding door. The opening and closing direction of the opening and closing body is arbitrary, and includes, for example, the horizontal direction, the vertical direction, etc.

In addition, in the embodiment, the "open/close state of the opening/closing body" is a concept that includes a fully closed state, a fully open state, and a half-open state.

Of these, the "fully closed state" is a state in which the opening is fully closed by the opening/closing body, and the position of the opening/closing body in this fully closed state is referred to as the "fully closed position." Additionally, the "fully open state" is a state in which the opening is fully opened by the opening/closing body, and the position of the opening/closing body in this fully open state is referred to as the "fully open position." Additionally, the "half-open state" is a state in which the opening/closing body is located between the fully closed position and the fully open position, and the position of the opening/closing body in this half-open state is referred to as the "half-open position."

In the following embodiment, we will explain the case where the opening and closing body of the automatic door system is a single-sliding door installed in a position facing the corridor of a building such as a commercial facility.

[II] Specific Contents of the Embodiment Next, specific contents of the embodiment will be described.

The first pulley portion 50a and the second pulley portion 50b are each constructed using, for example, a known pulley member for an automatic door device (as an example, a pulley member including a pulley body 51 and a rotating shaft 52 for rotating the pulley body 51), and are provided in a portion corresponding to the inspection hatch 13a inside the blind 13 as shown in Fig. 3.

Specifically, the first pulley portion 50a and the second pulley portion 50b are disposed above the rail portion 20 and spaced apart by a distance D1 (hereinafter referred to as the "first distance D1") approximately along the opening/closing direction (the left-right direction in FIG. 3). The rotating shaft 52 of the first pulley portion 50a is connected to the drive portion 60 so as to be rotatable, and the rotating shaft 52 of the second pulley portion 50b is fixed directly or indirectly to the eyelet 13 by a fixing device or the like.

The drive unit 60 is a drive means for rotating the first pulley unit 50a. The drive unit 60 is configured using, for example, a drive motor for a known automatic door device, and is provided inside the interlock 13 near the first pulley unit 50a as shown in FIG.

Specifically, it is fixed directly or indirectly to the blind 13 by a fixing device or the like.

(Configuration-Drive System-First Connection Part, Second Connection Part)
The first connection part 70a is a first connection means that connects the opening-closing body 30 and the towing part 80, and the second connection part 70b is different from the first connection part 70a and is a second connection means that connects the opening-closing body 30 and the towing part 80. The first connection part 70a and the second connection part 70b are each configured using, for example, a known connection member (a belt holder as one example), and are provided inside the blind 13 as shown in FIG.

Specifically, the first connection part 70a and the second connection part 70b are arranged at a distance D2 (hereinafter referred to as the "second distance D2") from each other approximately along the opening/closing direction (left-right direction in FIG. 3), and are connected to the guided part 32 (specifically, the guided side connection member 32b) and the towing part 80 provided on the opening/closing body main body 31 by fasteners or the like.

(Configuration-Drive System-Traction Unit)
The towing unit 80 is a towing means that tows the opening/closing body 30 substantially along the opening/closing direction in accordance with the rotation of the first pulley unit 50a and the second pulley unit 50b. The towing unit 80 is configured using, for example, a known towing member (e.g., a long belt with ends), and is provided in a portion inside the blind 13 that corresponds to the inspection hatch 13a, as shown in FIG.

Specifically, one end of the towing unit 80 (in FIG. 3, the end of the towing unit 80 on the door leading side) is connected to the first connection unit 70a, and the other end of the towing unit 80 (in FIG. 3, the end of the towing unit 80 on the door trailing side) is connected to the second connection unit 70b. The configuration of the drive system 40 will be described in detail later.

(Configuration - Switching Control Device)
Returning to FIG. 1, the opening/closing control device 90 is a device for controlling the opening/closing movement of the opening/closing body 30, and as shown in FIG.

(Configuration-Opening and closing control device-Detection unit)
The detection unit 91 is a detection means that detects whether or not a passing object (for example, a person, an animal, an object, etc.) has entered a detection area (not shown).

The "detection area" here refers to an area located near the opening 2 in the forward (front-back) direction. Also, "nearby" refers to a range of positions away from the opening 2, where if a passing object is present within that range, it is estimated that the passing object will be highly likely to pass through the opening 2. For example, this range would be up to a position a predetermined distance (e.g., 1 m) away from the opening 2 in the forward (front-back) direction.

The detection unit 91 is configured, for example, using a known detection sensor (such as a quantum infrared sensor), and is provided on each of the exterior surfaces of the inspection cover 13b and the blind 13, as shown in Figures 1 and 2.

(Configuration-Opening and Closing Control Device-Position Detection Unit)
The position detection unit is a position detection means that detects the position of the opening/closing body 30. This position detection unit is configured using, for example, a known detection sensor (e.g., a rotary encoder or the like), is provided inside the transom 13 in the vicinity of the drive unit 60, and is fixed to the drive unit 60 by a fixture or the like.

(Configuration-Switching Control Device-Control Unit)
The control unit 92 is a unit for controlling the opening/closing control device 90. This control unit 92 is configured using, for example, a control unit for an automatic door device, is provided inside the transom 13 in the vicinity of the drive unit 60, and includes a communication unit, a power supply unit, a control unit, and a memory unit.

Of these, the communication unit is a communication means for communicating with each of the drive unit 60, the detection unit 91, and the position detection unit via wiring.

The power supply unit is a power supply means that supplies power from an external power source to each part of the control unit 92 via wiring, and also supplies power to the drive unit 60, detection unit 91, and position detection unit via wiring.

The control unit is a control means that controls each part of the control unit 92, and specifically, is a computer that is equipped with a CPU, various programs that are interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are started on the OS and realize specific functions), and an internal memory such as a RAM for storing programs and various data.

The storage unit is a storage means for storing programs and various data necessary for the operation of the control unit 92, and is configured using a rewritable recording medium, for example, a non-volatile recording medium such as a flash memory.

(Configuration - Drive system configuration details)
Next, a detailed description will be given of the configuration of the drive system 40. However, unless otherwise specified, the drive system 40 can be manufactured in any shape, by any method, and with any material.

In this embodiment, the features of the drive system 40 are as follows:

(Configuration - Drive System Configuration Details - First Feature)
First, regarding the first feature of the drive system 40, the first pulley portion 50a, the second pulley portion 50b, the first connecting portion 70a, and the second connecting portion 70b are arranged so that the length of the movement stroke MS of the opening/closing body 30 towed by the towing portion 80 is longer than the length of the first distance D1.

Here, the "movement stroke MS of the opening/closing body 30" refers to the stroke (movement distance) that the opening/closing body 30 can move to open and close, and in the embodiment, as shown in Figure 3, is described as a distance that is shorter than the left-right length CL of the inspection hatch 13a, and is the distance from the end of the opening 2 on the closing direction side to a position slightly further to the closing direction side than the indoor side mullion 14 (or the outdoor side mullion 15).

The "remaining dimension LD of the opening 2" refers to the left-right length of the part of the opening/closing body 30 that is not stored in the door pocket 18 when fully open, and in the embodiment, it is described as the distance from a position slightly to the closing direction side of the interior mullion 14 (or the exterior mullion 15) to the interior mullion 14 (or the exterior mullion 15), as shown in Figure 3.

Specifically, first, the first pulley portion 50a, the second pulley portion 50b, the first connection portion 70a, and the second connection portion 70b are arranged so that, in the fully closed state, either the first connection portion 70a or the second connection portion 70b is located closer to the closing direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b, and/or, in the fully open state, the other of the first connection portion 70a or the second connection portion 70b is located closer to the opening direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b.

More specifically, as shown in FIG. 3, the first pulley section 50a is positioned near the indoor side upright 14 (or the outdoor side upright 15) (in FIG. 3, a position closer to the closing direction than the indoor side upright 14), and the second pulley section 50b is positioned between the closing end of the opening 2 and the indoor side upright 14 (or the outdoor side upright 15) (in FIG. 3, a position closer to the closing direction than approximately the center of the inspection hatch 13a in the left-right direction).

The first and second connection parts 70a and 70b are arranged so that, in the fully closed state, the first connection part 70a is located closer to the closing direction of the opening 2 than the first and second pulley parts 50a and 50b (to the left of the opening 2 in FIG. 3), and, in the fully open state, the second connection part 70b is located closer to the opening direction of the opening 2 than the first and second pulley parts 50a and 50b (to the right of the opening 2 in FIG. 4). In particular, in FIG. 3 and FIG. 4, the first connection part 70a is arranged near the leading end of the opening/closing body 30, and the second connection part 70b is arranged near the trailing end of the opening/closing body 30.

This arrangement ensures that the length of the first interval D1 can be shortened, and the size of the inspection hatch 13a can be reduced.

The pulling part 80 is arranged so that it winds around the first pulley part 50a and the second pulley part 50b, passing through the first connection part 70a, the first pulley part 50a, the second pulley part 50b, and the second connection part 70b in that order. Here, in the embodiment, "winding" means that the opening/closing body 30 is wound around so as to be pulled by the pulling part 80 as the first pulley part 50a and the second pulley part 50b rotate.

More specifically, as shown in FIG. 3, the end of the pulling part 80 on the door leading side is connected to the first connection part 70a, and the end of the pulling part 80 on the door trailing side is connected to the second connection part 70b. The pulling part 80 is positioned so that it abuts against the outer edge of the pulley body 51 of each of the first pulley part 50a and the second pulley part 50b.

This arrangement ensures that the length of the first interval D1 can be shortened, and the size of the inspection hatch 13a (specifically, the left-right length CL of the inspection hatch 13a) can be reduced.

The length of the second interval D2 is set to be longer than the length of the first interval D1.

More specifically, as shown in FIG. 3, the length of the first interval D1 and the length of the second interval D2 are each set shorter than the left-right length CL of the inspection hatch 13a. The length of the first interval D1 is set to about half the left-right length CL of the inspection hatch 13a. The length of the second interval D2 is set longer than the length of the first interval D1 and longer than the movement stroke MS of the opening/closing body 30 so that in the fully open state, the first connection portion 70a is located closer to the closing direction of the opening 2 (left side in FIG. 4) than the first pulley portion 50a.

By setting it in this way, the length of the movement stroke MS of the opening/closing body 30 can be made longer than when the length of the second interval D2 is shorter than the length of the first interval D1, making it easier to reduce the size of the inspection hatch 13a.

Due to the first feature described above, the length of the first interval D1 can be made shorter than in the conventional technology (technology in which the opening/closing body 30 is opened and closed by the rotation of a ring-shaped toothed belt wound around the driving pulley and the driven pulley). Therefore, even if the drive system 40 is configured using conventional members (specifically, the first pulley unit 50a, the second pulley unit 50b, and the drive unit 60), the size of the inspection hatch 13a for inspecting the above members can be made smaller, and the maintenance of the drive system 40 can be ensured while suppressing the installation cost of the drive system 40. In addition, compared to the conventional technology in which the distance between the driving pulley and the driven pulley is shortened and the width of the inspection hatch is shortened, the first connection unit 70a can be easily arranged near the door end side end of the opening/closing body 30 regardless of the arrangement positions of the first pulley unit 50a and the second pulley unit 50b, so that the remaining dimension LD of the opening 2 can be prevented from becoming large, and the passage of the opening 2 can be easily ensured.

(Configuration - Drive System Configuration Details - Second Feature)
Regarding the second feature of the drive system 40, the first pulley unit 50a and the second pulley unit 50b are arranged so that the axial directions of the rotating shafts 52 of the first pulley unit 50a and the second pulley unit 50b are approximately the same, and the first pulley unit 50a and the second pulley unit 50b are positioned at different positions in the axial direction.

Specifically, as shown in FIG. 3, the first pulley portion 50a and the second pulley portion 50b are arranged so that the axial direction of the rotation shaft 52 of each of the first pulley portion 50a and the second pulley portion 50b is approximately along the vertical direction. The first pulley portion 50a and the second pulley portion 50b are also arranged so that the first pulley portion 50a and the second pulley portion 50b are at different positions in the vertical direction. More specifically, the first pulley portion 50a is arranged so that it is located above the second pulley portion 50b and the first pulley portion 50a is arranged so that it is located above the second connection portion 70b.

In this case, the towing section 80 is positioned so that the portion of the towing section 80 extending from the first pulley section 50a to the second pulley section 50b is inclined in the left-right direction.

The first connection part 70a is configured with the second pulley part 50b so that the first connection part 70a does not come into contact with the second pulley part 50b regardless of the opening/closing state of the opening/closing body 30. Specifically, the first connection part 70a is formed of a plate-shaped body with a substantially U-shaped side shape, and when the opening/closing state of the opening/closing body 30 is switched from the fully closed state to the fully open state, even if the first connection part 70a and the second pulley part 50b overlap when viewed from the planar direction, the first connection part 70a and the second pulley part 50b are arranged so that the second pulley part 50b is located between the upper and lower pieces of the first connection part 70a through the open end of the U-shaped part of the first connection part 70a. This allows the opening/closing body 30 to be opened and closed smoothly while avoiding contact between the first connection part 70a and the second pulley part 50b.

This second feature makes it easier to avoid the first pulley portion 50a and the second pulley portion 50b coming into contact with the first connecting portion 70a and the second connecting portion 70b during the opening and closing movement of the opening and closing body 30, thereby ensuring the length of the movement stroke MS of the opening and closing body 30.

However, this is not limiting, and for example, the first pulley part 50a and the second pulley part 50b may be arranged so that the axial direction of the rotation shaft 52 of each of the first pulley part 50a and the second pulley part 50b is approximately along the front-rear direction, and the first pulley part 50a and the second pulley part 50b may be arranged so that the first pulley part 50a and the second pulley part 50b are at different positions from each other in the front-rear direction.

(Configuration - Drive System Configuration Details - Third Feature)
Regarding the third feature of the drive system 40, the first pulley unit 50a and the second pulley unit 50b are disposed at positions corresponding to the opening/closing body 30 in the fully closed state.

Specifically, as shown in FIG. 3, the first pulley unit 50a and the second pulley unit 50b are arranged so as to be located directly above the opening/closing body 30 in the fully closed state. More specifically, they are arranged in a portion of the interior of the transom 13 that is located directly above the opening 2 and corresponds to the inspection hatch 13a. In particular, in FIG. 3, the first pulley unit 50a and the second pulley unit 50b are arranged inside the transom 13 at a position closer to the opening direction of the opening 3 than the leading end of the opening/closing body 30 in the fully closed state, and at a position closer to the closing direction of the opening 3 than the trailing end of the opening/closing body 30, and the first pulley unit 50a is arranged at a position closer to the closing direction of the opening 3 than the second pulley unit 50b.

This third feature makes it possible to provide the first pulley portion 50a and the second pulley portion 50b in a position that allows maintenance regardless of whether the opening/closing body 30 is open or closed, for example, when the automatic door device 1 is a type that fits into a door pocket board, making it easier to ensure maintainability of the drive system 40.

(Action of sliding door)
Next, the operation of the automatic door system 1 configured as described above will be described.

That is, for example, when the drive unit 60 is driven by the control unit of the opening/closing control device 90, the rotational force of the first pulley unit 50a (specifically, the pulley body 51) sends out the towing unit 80 in the opening/closing direction via the first pulley unit 50a and the second pulley unit 50b, and the opening/closing body 30 is pulled approximately along the opening/closing direction by the towing unit 80 that is sent out. Through this series of operations, the opening/closing body 30 can be moved in the opening/closing direction so that the opening/closing state of the opening/closing body 30 becomes the fully closed state in FIG. 3, the fully open state in FIG. 4, or the half-open state.

As shown in FIG. 3, when the opening/closing body 30 is in the fully closed state, the first pulley portion 50a, the second pulley portion 50b, the first connection portion 70a, and the second connection portion 70b are arranged so that the length of the movement stroke MS of the opening/closing body 30 is longer than the length of the first interval D1, as described above. Therefore, when the inspection cover 13b is removed from the blind 13 (hereinafter referred to as the "removed state"), the first pulley portion 50a, the second pulley portion 50b, the drive portion 60, the first connection portion 70a, the second connection portion 70b, and the towing portion 80 (i.e., the entire drive system 40) are exposed to the outside through the inspection opening 13a, whose left-right length CL is shorter than the left-right length of the blind 13. This makes it possible to efficiently inspect the entire drive system 40 through the inspection opening 13a.

As shown in FIG. 4, when the opening/closing body 30 is in a fully open state (or half-open state), in the removed state, the first pulley portion 50a, the second pulley portion 50b, the drive portion 60, the first connection portion 70a, and a portion of the towing portion 80 are exposed to the outside through the inspection hatch 13a. This makes it possible to efficiently inspect some of the components of the drive system 40 through the inspection hatch 13a.

(Effects of the embodiment)
Thus, according to the embodiment, there are provided the first pulley portion 50a and the second pulley portion 50b spaced apart from each other by a first distance D1 approximately along the opening/closing direction, a drive portion 60 for rotating the first pulley portion 50a, a first connection portion 70a and a second connection portion 70b connected to the opening/closing body 30, the first connection portion 70a and the second connection portion 70b being spaced apart from each other by a second distance D2 approximately along the opening/closing direction, and a pulling portion 80 that pulls the opening/closing body 30 approximately along the opening/closing direction as the first pulley portion 50a and the second pulley portion 50b rotate, The towing unit 80 has a first end connected to the first connection portion 70a and the other end connected to the second connection portion 70b, and the first pulley portion 50a, the second pulley portion 50b, the first connection portion 70a, and the second connection portion 70b are arranged so that the length of the movement stroke MS of the opening/closing body 30 towed by the towing unit 80 is longer than the length of the first interval D1. Therefore, the length of the first interval D1 can be shortened compared to the conventional technology (a technology in which the opening/closing body 30 is moved to open and close with the rotation of a ring-shaped toothed belt wound around a driving pulley and a driven pulley). Therefore, even if the drive system 40 is configured using conventional members (specifically, the first pulley portion 50a, the second pulley portion 50b, and the drive unit 60), the size of the inspection hole 13a for inspecting the above members can be reduced, and the maintainability of the drive system 40 can be ensured while suppressing the installation cost of the drive system 40. In addition, the remaining dimension LD of the opening 2 can be prevented from becoming large, making it easier to ensure the passage through the opening 2.

In addition, the first pulley portion 50a, the second pulley portion 50b, the first connection portion 70a, and the second connection portion 70b are arranged so that in the fully closed state, either the first connection portion 70a or the second connection portion 70b is located closer to the closing direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b, and in the fully open state, the other of the first connection portion 70a or the second connection portion 70b is located closer to the opening direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b. This ensures that the length of the first interval D1 can be shortened, and the size of the inspection hatch 13a can be reduced.

In addition, the towing part 80 is positioned so that it winds around the first pulley part 50a and the second pulley part 50b while passing through the first connection part 70a, the first pulley part 50a, the second pulley part 50b, and the second connection part 70b in that order, so the length of the first interval D1 can be reliably shortened, and the size of the inspection hatch 13a can be reliably reduced.

In addition, since the length of the second interval D2 is longer than the length of the first interval D1, the length of the movement stroke MS of the opening/closing body 30 can be longer than when the length of the second interval D2 is shorter than the length of the first interval D1, making it easier to reduce the size of the inspection hatch 13a.

In addition, the first pulley portion 50a and the second pulley portion 50b are arranged so that the axial directions of the rotation shafts 52 of the first pulley portion 50a and the second pulley portion 50b are substantially the same, and the first pulley portion 50a and the second pulley portion 50b are positioned at different positions in the axial direction. This makes it easier to avoid the first pulley portion 50a and the second pulley portion 50b coming into contact with the first connecting portion 70a or the second connecting portion 70b during the opening and closing movement of the opening and closing body 30, and ensures the length of the movement stroke MS of the opening and closing body 30.

In addition, since the first pulley portion 50a and the second pulley portion 50b are positioned in a position corresponding to the opening/closing body 30 in the fully closed state, for example, if the automatic door device 1 is a type that fits into a door pocket board, the first pulley portion 50a and the second pulley portion 50b can be located in a position where they can be maintained regardless of the open/closed state of the opening/closing body 30, making it easier to ensure the maintainability of the drive system 40.

[III] Modifications to the embodiments The embodiments of the present invention have been described above, but the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of each invention described in the claims. Such modifications will be described below.

(About the problem to be solved and the effects of the invention)
First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and the present invention may solve problems that are not described above or achieve effects that are not described above, or may solve only some of the problems that are described or achieve only some of the effects that are described.

(shape, number, structure, time series)
The components illustrated in the embodiments and drawings may be modified and improved as desired within the scope of the technical concept of the present invention with respect to the shape, numerical values, or structure or chronological relationships of multiple components.

(About automatic door systems)
In the above embodiment, the automatic door system 1 has been described as including the door pocket 18, but this is not limiting, and for example the door pocket 18 may be omitted. In this case, the inspection hatch 13a may be located on the surface of the transom 13 facing the interior of the room, at the tip end of the transom 13, the central part in the left-right direction of the transom 13, or the trailing end of the transom 13. The drive system 40 may be located inside the transom 13 at a position corresponding to the inspection hatch 13a.

(About the opening and closing body)
In the above embodiment, it has been described that the opening/closing body 30 has a guided portion 32, a door-leading side door stop portion, and a door-trailing side door stop portion 34, but this is not limited to the above, and for example, at least one of the guided portion 32, the door-leading side door stop portion, or the door-trailing side door stop portion 34 may be omitted.

(Regarding inspection hatches)
In the above embodiment, it has been described that the inspection hatch 13a is provided on the surface of the glazed window 13 facing the interior of the room, but this is not limited thereto, and the inspection hatch 13 may be provided, for example, on the surface of the glazed window 13 facing the exterior of the room.

(Regarding the drive system)
In the above embodiment, the first pulley portion 50a, the second pulley portion 50b, the first connection portion 70a, and the second connection portion 70b are arranged so that in the fully closed state, either the first connection portion 70a or the second connection portion 70b is located closer to the closing direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b, and in the fully open state, either the first connection portion 70a or the second connection portion 70b is located closer to the opening direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b. However, the present invention is not limited to this. For example, either the first connection portion 70a or the second connection portion 70b may be arranged so that in the fully closed state, either the first connection portion 70a or the second connection portion 70b is located closer to the closing direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b, but in the fully open state, the first connection portion 70a and the second connection portion 70b are not located closer to the opening direction of the opening 2 than the first pulley portion 50a and the second pulley portion 50b. Alternatively, in the fully closed state, the first connection portion 70a and the second connection portion 70b are not located on the closing direction side of the opening 2 relative to the first pulley portion 50a and the second pulley portion 50b, but in the fully open state, the other of the first connection portion 70a or the second connection portion 70b may be positioned on the opening direction side of the opening 2 relative to the first pulley portion 50a and the second pulley portion 50b.

(Regarding the first pulley section and the second pulley section)
In the above embodiment, the first pulley portion 50a is described as being disposed above the second pulley portion 50b, but this is not limiting. For example, when the first connection portion 70a is disposed forward (or rearward) of the second pulley portion 50b so that the first connection portion 70a and the second connection portion 70b do not come into contact with the first pulley portion 50a and the second pulley portion 50b, the first pulley portion 50a may be disposed below the second pulley portion 50b.

In the above embodiment, the first pulley portion 50a and the second pulley portion 50b are described as being positioned in correspondence with the opening/closing body 30 in the fully closed state, but this is not limited thereto. For example, if the automatic door device 1 is not a door pocket board type, at least a portion of the first pulley portion 50a and the second pulley portion 50b may be positioned in a position that does not correspond to the opening/closing body 30 in the fully closed state. As an example, the first pulley portion 50a and the second pulley portion 50b may be positioned so that they are not located directly above the opening/closing body 30 in the fully closed state.

In the above embodiment, the number of pulley means is two, but the number may be three or more. In this case, for example, when the first pulley portion 50a, the second pulley portion 50b, and the third pulley portion are provided as the pulley means, the pulling portion 80 may be arranged so that the pulling portion 80 winds around the first pulley portion 50a, the second pulley portion 50b, and the third pulley portion while passing through the first connection portion 70a, the first pulley portion 50a, the second pulley portion 50b, the third pulley portion, and the second connection portion 70b in that order.

In the above embodiment, the first pulley portion 50a is arranged in the vicinity of the indoor side upright 14 (or the outdoor side upright 15), and the second pulley portion 50b is arranged in the position between the closed end of the opening 2 and the indoor side upright 14 (or the outdoor side upright 15), but this is not limited to the above. For example, the first pulley portion 50a may be arranged in the position between the closed end of the opening 2 and the indoor side upright 14 (or the outdoor side upright 15), and the second pulley portion 50b may be arranged in the vicinity of the indoor side upright 14 (or the outdoor side upright 15). In this case, the pulling portion 80 may be arranged so that it winds around the first pulley portion 50a and the second pulley portion 50b, passing through the first connecting portion 70a, the second pulley portion 50b, the first pulley portion 50a, and the second connecting portion 70b in this order.

(Regarding the towing section)
In the above embodiment, the traction unit 80 is described as a belt with ends. However, the traction unit 80 is not limited to this and may be, for example, a wire with ends or a chain with ends.

(First and second intervals)
In the above embodiment, the length of the first interval D1 is set to about half the length CL of the inspection hatch 13a in the left-right direction, but this is not limiting, and for example, the length may be set shorter (or longer) than half the length CL of the inspection hatch 13a in the left-right direction. In this case, the length of the second interval D2 may be set shorter than the length of the second interval D2 in the above embodiment, and the length CL of the inspection hatch 13a in the left-right direction may be set shorter than the length CL of the inspection hatch 13a in the above embodiment.

In addition, in the above embodiment, it has been described that the length of the second interval D2 is set to be longer than the length of the first interval D1, but this is not limited thereto, and it may be set, for example, to be shorter than the length of the first interval D1.

(Effect of supplementary notes)
According to the drive system for an automatic door device described in Supplementary Note 1 and the automatic door device described in Supplementary Note 7, there is provided a second pulley means provided at a first interval from the first pulley means substantially along the opening/closing direction, a drive means for rotating the first pulley means, a first connection means and a second connection means connected to the opening/closing body, the first connection means and the second connection means provided at a second interval from each other substantially along the opening/closing direction, and a pulling means for pulling the opening/closing body substantially along the opening/closing direction as the first pulley means and the second pulley means rotate, The towing means includes a towing means having one end connected to the first connecting means and the other end connected to the second connecting means, and the first pulley means, the second pulley means, the first connecting means, and the second connecting means are arranged so that the length of the movement stroke of the opening/closing body towed by the towing means is longer than the length of the first interval, so that the length of the first interval can be shortened compared to the conventional technology (a technology in which the opening/closing body is moved to open and close with the rotation of a ring-shaped toothed belt wound around a driving pulley and a driven pulley). Therefore, even if the drive system is configured using conventional members (specifically, the first pulley means, the second pulley means, and the drive means), the size of the inspection opening for inspecting the above members can be reduced, and the maintainability of the drive system can be ensured while suppressing the installation cost of the drive system. In addition, the remaining dimension of the opening can be avoided from becoming large, making it easier to ensure the passage of the opening.

According to the drive system for an automatic door device described in Appendix 2, the first pulley means, the second pulley means, the first connection means, and the second connection means are arranged so that in the fully closed state, either the first connection means or the second connection means is located closer to the closing direction of the opening than the first pulley means and the second pulley means, and/or in the fully open state, the other of the first connection means or the second connection means is located closer to the opening direction of the opening than the first pulley means and the second pulley means, so that the length of the first interval can be reliably shortened and the size of the inspection hatch can be reliably reduced.

According to the drive system for an automatic door device described in Appendix 3, the traction means is arranged so that it passes through the first connection means, the first pulley means, the second pulley means, and the second connection means in that order, winding around the first pulley means and the second pulley means. This ensures that the length of the first interval can be shortened, and the size of the inspection hatch can be reduced.

According to the drive system for the automatic door device described in Appendix 4, the length of the second interval is longer than the length of the first interval, so the length of the movement stroke of the opening/closing body can be longer than when the length of the second interval is shorter than the length of the first interval, making it easier to reduce the size of the inspection hatch.

According to the drive system for an automatic door device described in Appendix 5, the first pulley means and the second pulley means are arranged so that the axial directions of the rotation shafts of the first pulley means and the second pulley means are substantially the same, and the first pulley means and the second pulley means are positioned differently from each other in the axial direction. This makes it easier to avoid the first pulley means and the second pulley means coming into contact with the first connecting means or the second connecting means during the opening and closing movement of the opening and closing body, and ensures the length of the movement stroke of the opening and closing body.

According to the drive system for an automatic door device described in Appendix 6, the first pulley means and the second pulley means are positioned in a position that corresponds to the opening and closing body in the fully closed state. Therefore, for example, if the automatic door device is a type that fits into a door pocket board, the first pulley means and the second pulley means can be placed in a position that allows maintenance regardless of the open/close state of the opening and closing body, making it easier to ensure the maintainability of the drive system.
