Description

[Technical field]

[0001] The present invention relates to a drive system for an automatic door system, and to an automatic door system. [Background technology]

[0002] Conventionally, a system for moving an opening / closing body of an automatic door device installed in an opening in a wall of a building to open and close has been proposed. Such a system includes, for example, a driving pulley and a driven pulley installed at a distance from each other along the opening / closing direction of the opening / closing body inside the blind, a circular toothed belt wound around the driving pulley and the driven pulley, a connector connecting the toothed belt and the opening / closing body, and a motor for moving the opening / closing body to open and close with the rotation of the toothed belt by rotating the driving pulley (for example, see 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 / closing body can move to open and close, 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. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2013-234567 A Summary of the Invention [Problem to be solved by the invention]

[0004] 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 interlock (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, so 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 was a risk that it would be difficult to ensure the maintainability of the above conventional system.

[0005] 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 side 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 remaining dimension of the opening is set relatively large and the effective opening width of the opening is shortened, which may make it difficult to ensure passage through the opening.

[0006] On the other hand, in order to avoid the above-mentioned problems, it is conceivable to use a linear engine instead of the above-mentioned conventional system to open and close the opening and closing body connected by the slider of the linear engine. However, since the linear engine is very expensive, there is a concern that the installation cost of the system will be excessively high.

[0007] For the reasons mentioned above, there was room for improvement in terms of the maintainability and installation costs of the system, as well as the passability through the openings.

[0008] The present invention is intended to solve the problems associated with the above-mentioned conventional technology, and has as its object to provide a drive system for an automatic door system, and an automatic door system, which makes it possible to reduce the installation costs of the drive system, while ensuring maintainability of the drive system and ensuring passability through the opening.

[0015] The automatic door system according to the seventh aspect of the present invention comprises the drive system for the automatic door system according to any one of the first to sixth aspects of the present invention. Effect of the Invention

[0016] According to the drive system for an automatic door system of claim 1 and the automatic door system of claim 7, there are 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 has one end connected to the first connection means and the other end connected to the second connection means, and the first pulley means, the second pulley means, the first connection means, and the second connection means are arranged so that the length of the movement stroke of the opening / closing body pulled by the towing means is longer than the length of the first interval, so that the length of the first interval can be made shorter than that of the conventional technology (a technology in which the opening / closing body is moved to open and close with the rotation of a circular 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 made small, 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 prevented 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 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.

[0017] According to the drive system for an automatic door device described in claim 2, the first pulley means, the second pulley means, the first connecting means and the second connecting means are arranged so that in the fully closed state, either the first connecting means or the second connecting means is located closer to the closing direction of the opening than the first pulley means and the second pulley means, and / or so that in the fully open state, the other of the first connecting means or the second connecting means is located closer to the opening direction of the opening than the first pulley means and the second pulley means, thereby ensuring a short length of the first interval and a small size of the inspection hatch.

[0018] According to the drive system for an automatic door device described in claim 3, the traction means is arranged so that it winds around the first pulley means and the second pulley means while passing through the first connecting means, the first pulley means, the second pulley means, and the second connecting means in that order, thereby ensuring that the length of the first interval is short and the size of the inspection hatch is small.

[0019] According to the drive system for an automatic door device described in claim 4, the length of the second interval is made longer than the length of the first interval, so that the length of the movement stroke of the opening / closing body can be made longer than when the length of the second interval is made shorter than the length of the first interval, making it easier to reduce the size of the inspection hatch.

[0020] According to the drive system for an automatic door system as set forth in claim 5, Since the first pulley means and the second pulley means are positioned in a position corresponding to the opening / closing body in the fully closed state, for example, if the automatic door device is a type that is fitted into a door pocket board, the first pulley means and the second pulley means can be located in a maintainable position regardless of the open / closed state of the opening / closing body, making it easier to ensure the maintainability of the drive system.

[0021] According to the drive system for an automatic door system as set forth in claim 6, The device comprises a second pulley means arranged at a first interval from the first pulley means approximately 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 arranged at a second interval from each other approximately along the opening / closing direction, and a traction means for towing the opening / closing body approximately along the opening / closing direction as the first pulley means and the second pulley means rotate, the traction means having one end connected to the first connection means and the other end connected to the second connection means, and the first pulley means, the second pulley means, the first connection means, and the second connection means are arranged so that the length of the movement stroke of the opening / closing body pulled by the traction means is longer than the length of the first interval, and therefore the length of the first interval can be shorter than the conventional technology (technology in which the opening / closing body is moved open and closed as a result of rotation of a circular toothed belt wound around a drive pulley and a driven pulley). Therefore, even if the drive system is constructed using conventional members (specifically, the first pulley means, the second pulley means, and the drive means), the size of the inspection hatch 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, it is possible to avoid the remaining dimension of the opening from becoming large, making it easier to ensure the passability of the opening. [Brief description of the drawings]

[0037] The method of mounting (or connecting) the various components that make up the automatic door device 1 is arbitrary; for example, a method of mounting (or connecting) the mounting side component to the mating component using fasteners (e.g. rivets, mounting screws, screws, etc.), welding, adhesives, double-sided tape, etc. through mounting holes (e.g. rivet holes, screw holes, screw holes, etc.) formed in the mounting side component or the mating component.

[0038] (Structure - Frame) Returning to Figure 1, the frame body 10 is provided on the periphery of the opening 2, and as shown in Figures 1 and 2, comprises a vertical door end frame member 11, a vertical door end frame member 12, a mullion 13, an interior side upright 14, an exterior side upright 15, an interior side door pocket board body 16, and an exterior side door pocket board body 17.

[0039] (Configuration - Frame - Vertical door frame material) Returning to Fig. 1, the door-end vertical frame member 11 is a frame member provided on the door-end side among the frame members that make up the frame body 10. This door-end vertical frame member 11 is made up of, for example, a known frame member for sliding doors (as an example, a long steel frame member), and as shown in Fig. 1, the longitudinal direction of the door-end vertical frame member 11 is arranged along the up-down direction, and it is fixed to the building frame 3 (for example, a wall or a pillar) by a fixing device or the like.

[0040] (Configuration - Frame - Vertical door frame material) The end-of-door vertical frame member 12 is a frame member provided on the end-of-door side among the frame members that constitute the frame body 10. This end-of-door vertical frame member 12 is constructed, for example, using a known frame member for a sliding door (for example, a long steel frame member), and as shown in Fig. 1, the longitudinal direction of the end-of-door vertical frame member 12 is arranged along the vertical direction, and is fixed to the building frame 3 by a fastener or the like.

[0041] (Configuration - Frame - No eyes) The transom 13 is a frame material provided at the upper side among the frame materials constituting the frame body 10, and is a frame material for storing each part of the automatic door device 1. The transom 13 is a long hollow body (for example, a long hollow body made of steel) that is roughly aligned in the left-right direction, and is specifically configured to be able to store the rail part 20, the drive system 40, and a position detection part and a control unit 92 of the opening / closing control device 90 described below.

[0042] As shown in FIG. 1(a), the inlet 13 is provided with an inspection hatch 13a and an inspection cover 13b.

[0043] (Configuration - Frame - Gate - Inspection hatch) The inspection hatch 13a is an opening for inspecting the drive system 40, and is formed in the surface of the transom 13 facing the interior of the room.

[0044] Furthermore, the specific configuration of inspection hatch 13a is arbitrary, but in this embodiment it is configured as follows.

[0045] That is, the shape of the inspection hatch 13a is set to a substantially rectangular shape, but is not limited to this, and may be set to, for example, a substantially elliptical shape.

[0046] The left-right length CL of inspection hatch 13a is set shorter than the left-right length of transom 13, and more specifically, is set approximately the same as the length from the door-front end of transom 13 to the room-side mullion 14. The up-down length of inspection hatch 13a is set approximately the same as the up-down length of transom 13.

[0047] Regarding the installation method of the inspection hatch 13a, it is installed on the surface of the glazed door 13 facing the interior of the room, from the end of the glazed door 13 on the door front side to the interior side mullion 14.

[0051] (Composition - Frame - Interior door pocket board) Returning to FIG. 1, the indoor door pocket board body 16 is a board that is provided on the indoor side of the room among the boards that constitute the door pocket 18. The indoor door pocket board body 16 is constructed using, for example, a known board body for door pockets, and is configured to include, for example, a plurality of reinforcing members 16a arranged in parallel approximately along the vertical direction at intervals from each other, a base board 16b provided between the reinforcing members 16a and attached to the reinforcing members 16a by fasteners or adhesive, etc., and a finishing board 16c attached to the reinforcing members 16a by fasteners, etc. so as to cover the outer surfaces of the reinforcing members 16a and the base board 16b, and formed integrally with (or formed separately from) the surrounding wall material. As shown in FIG. 1, the indoor door pocket board body 16 is disposed in an area surrounded by the door end vertical frame member 12 and the indoor side mullion 14, and is fixed to the door end vertical frame member 12 and the indoor side mullion 14 by fasteners, etc., via a base material not shown.

[0052] Furthermore, the specific configuration of the indoor door pocket board body 16 is arbitrary, but in the embodiment, as shown in Figure 3(a), the finishing board 16c of the indoor door pocket board body 16 is configured so that it covers not only the reinforcing material 16a and base board 16b of the indoor door pocket board body 16, but also the portion from the end of the door trailing edge on the indoor side surface of the lintel 13 to the indoor side mullion 14.

[0053] (Configuration - Frame - Exterior door pocket board) The exterior door pocket board body 17 is one of the boards that make up the door pocket 18 and is provided on the exterior side of the room. This exterior door pocket board body 17 is constructed, for example, in substantially the same manner as the interior door pocket board body 16, and as shown in Fig. 2, is placed in an area surrounded by the door end vertical frame material 12 and the exterior side upright 15, and is fixed to the door end vertical frame material 12 and the exterior side upright 15 by fasteners or the like via a base material (not shown).

[0054] Furthermore, the specific configuration of the exterior door pocket board body 17 is arbitrary, but in the embodiment, as shown in Figure 4(a), the finishing board 16c of the exterior door pocket board body 17 is configured so that it covers not only the reinforcing material 16a and base board 16b of the exterior door pocket board body 17, but also almost the entire exterior surface of the interlining 13 (excluding the portion corresponding to the detection unit 91).

[0055] Of the various parts of the frame 10 thus constructed, the door pocket 18 in Fig. 1(b) is formed as a space surrounded by the vertical door end frame material 12, the transom 13, the floor 4, the interior mullion 14, the exterior mullion 15, the interior door pocket board body 16, and the exterior door pocket board body 17. This door pocket 18 allows the opening / closing body 30 to be freely inserted and removed inside the door pocket 18, so that when the opening / closing body 30 is almost completely housed inside the door pocket 18, for example, it can be fully opened.

[0056] (Configuration - Rail section) The rail section 20 guides the opening / closing body 30 to move along the opening / closing direction (left-right direction in the embodiment) of the opening 2. The rail section 20 is an elongated body formed so that the cross section perpendicular to the left-right direction has a substantially L-shaped (or substantially U-shaped) shape, and as shown in Fig. 3, the rail section 20 is disposed inside the transom 13 so that the longitudinal direction of the rail section 20 is substantially along the left-right direction, and is fixed to the transom 13 by a fixture or the like.

[0057] (Configuration - Opening and closing body) Returning to Figure 1, the opening / closing body 30 is used to open and close the opening 2, and as shown in Figures 1 to 4, it comprises an opening / closing body main body 31, a guided portion 32, a door-leading side door stop portion (not shown), and a door-trailing side door stop portion 34.

[0058] (Configuration - Opening / Closing Body - Opening / Closing Body Main Body) The opening / closing body main body 31 is the basic structure of the opening / closing body 30. This opening / closing body main body 31 is configured, for example, by using an opening / closing body for a known automatic door system (for example, an opening / closing panel for a single-sliding automatic door system). Specifically, as shown in Fig. 1, it includes an opening / closing body frame (not shown) made of steel (for example, steel, stainless steel, etc.) and a surface material 31a (for example, a steel decorative panel, etc.) attached so as to cover the entire front and back of the visible surface of the opening / closing body frame.

As shown in Figs. 3 and 4, the drive system 40 is provided inside the interlock 13, and includes a first pulley unit 50a, a second pulley unit 50b, a drive unit 60, a first connection unit 70a, a second connection unit 70b, and a traction unit 80.

[0063] (Configuration - Drive system - 1st pulley section, 2nd pulley section) Returning to Fig. 3, the first pulley portion 50a is a first pulley means that allows the opening / closing body 30 to be towed by the towing portion 80, and the second pulley portion 50b is different from the first pulley portion 50a and is a second pulley means that allows the opening / closing body 30 to be towed by the towing portion 80. The first pulley portion 50a and the second pulley portion 50b are each configured 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.

[0064] 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 "first distance D1") substantially along the opening / closing direction (left-right direction in FIG. 3). The rotating shaft 52 of the first pulley portion 50a is rotatably connected to the driving portion 60, and the rotating shaft 52 of the second pulley portion 50b is directly or indirectly fixed to the eyelet 13 by a fixing device or the like.

[0065] (Configuration - Drive system - Drive unit) 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.

[0066] Specifically, it is fixed directly or indirectly to the blind 13 by a fixing device or the like.

[0067] (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.

[0068] Specifically, the first connection portion 70a and the second connection portion 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 Figure 3), and are respectively connected to the guided portion 32 (specifically, the guided side connecting member 32b) and the towing portion 80 provided on the opening / closing body main body 31 by fasteners or the like.

[0069] (Configuration - Drive system - Traction unit) The traction unit 80 is a traction means that traction the opening / closing body 30 substantially along the opening / closing direction in association with the rotation of the first pulley unit 50a and the second pulley unit 50b. The traction unit 80 is configured using, for example, a known traction member (as one example, a long belt with ends), and is provided in a portion inside the interlock 13 that corresponds to the inspection hatch 13a, as shown in FIG.

[0070] Specifically, one end of the traction part 80 (in FIG. 3, the end of the traction part 80 on the door leading side) is connected to the first connection part 70a, and the other end of the traction part 80 (in FIG. 3, the end of the traction part 80 on the door trailing side) is connected to the second connection part 70b. The configuration of the drive system 40 will be described in detail later.

[0071] (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 includes a detection section 91, a position detection section (not shown), and a control unit 92, as shown in FIG.

[0072] (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).

[0073] Here, the "detection area" refers to an area located in the vicinity of the prospective direction (front-rear direction) of the opening 2. Also, the "vicinity" refers to a range of positions away from the opening 2, within which it is estimated that the probability of the passing object passing through the opening 2 is high if a passing object is present within the range of positions, and corresponds to, for example, a range up to a position a predetermined distance (e.g., 1 m) away from the opening 2 in the prospective direction (front-rear direction).

[0074] Furthermore, this detection unit 91 is constructed, for example, using a known detection sensor (for example, a quantum type infrared sensor, etc.), and is provided on each of the outdoor side surfaces of the inspection cover 13b and the blind 13, as shown in Figures 1 and 2.

[0075] (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 (such as a rotary encoder), is provided inside the interlock 13 in the vicinity of the drive unit 60, and is fixed to the drive unit 60 by a fixture or the like.

[0076] (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 interlock 13 in a position adjacent to the drive unit 60, and includes a communication unit, a power supply unit, a control unit, and a storage unit.

[0077] 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.

[0078] In addition, the power supply unit is a power supply means that supplies power supplied from an external power source to each part of the control unit 92 via wiring, and also supplies power to the drive unit 60, the detection unit 91, and the position detection unit via wiring.

[0079] The control unit is a control means for controlling each part of the control unit 92, and specifically, is a computer comprising a CPU, various programs interpreted and executed on the CPU (including basic control programs such as an OS, and application programs launched on the OS to realize specific functions), and an internal memory such as a RAM for storing programs and various data.

[0080] In addition, the memory 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.

[0081] (Configuration - Details of the configuration of the driving system) 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.

[0082] The features of the drive system 40 in this embodiment are as follows.

[0083] (Configuration - Drive system configuration details - First feature) First, regarding a 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 interval D1.

[0084] Here, "the movement stroke MS of the opening / closing body 30" means the stroke (movement distance) over which the opening / closing body 30 can move to open and close, and in the embodiment is described as a distance shorter than the left-right length CL of the inspection hatch 13a, as shown in Figure 3, and a 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 upright 14 (or the outdoor side upright 15).

[0085] In addition, 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 in the fully open state, and in the embodiment, it is described as the distance from a position slightly further in the closing direction than the indoor side upright 14 (or the outdoor side upright 15) to the indoor side upright 14 (or the outdoor side upright 15) as shown in Figure 3.

[0086] 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 a fully closed state, either the first connection portion 70a or the second connection portion 70b is located on the closing direction side of the opening 2 relative to the first pulley portion 50a and the second pulley portion 50b, and / or, in a fully open state, the other of the first connection portion 70a or the second connection portion 70b is located on the opening direction side of the opening 2 relative to the first pulley portion 50a and the second pulley portion 50b.

[0087] More specifically, as shown in Figure 3, the first pulley portion 50a is positioned near the indoor side upright 14 (or the outdoor side upright 15) (in Figure 3, a position on the closing direction side of the indoor side upright 14), and the second pulley portion 50b is positioned at a position between the closing side end of the opening 2 and the indoor side upright 14 (or the outdoor side upright 15) (in Figure 3, a position on the closing direction side of approximately the center of the inspection hatch 13a in the left-right direction).

[0088] The first connection part 70a and the second connection part 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 pulley part 50a and the second pulley part 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 pulley part 50a and the second pulley part 50b (to the right of the opening 2 in FIG. 4). In particular, in FIGS. 3 and 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.

[0089] With this arrangement, the length of the first interval D1 can be reliably shortened, and the size of the inspection hatch 13a can be reliably reduced.

[0090] The pulling part 80 is arranged so that the pulling part 80 winds around the first pulley part 50a and the second pulley part 50b while passing through the first connecting part 70a, the first pulley part 50a, the second pulley part 50b, and the second connecting part 70b in this order. Here, "winding" in the embodiment 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.

[0091] More specifically, as shown in FIG. 3, the pulling portion 80 is positioned so that its end on the door-front side is connected to the first connection portion 70a and its end on the door-tail side is connected to the second connection portion 70b, and so that the pulling portion 80 abuts against the outer edges of the pulley bodies 51 of the first pulley portion 50a and the second pulley portion 50b.

[0092] With this arrangement, the length of the first interval D1 can be reliably shortened, and the size of the inspection hatch 13a (specifically, the length CL of the inspection hatch 13a in the left-right direction) can be reliably reduced.

[0093] Moreover, the length of the second interval D2 is set to be longer than the length of the first interval D1.

[0094] 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 length CL of the inspection hatch 13a in the left-right direction. 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. 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 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 in the fully open state.

[0095] By setting it in this manner, 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.

[0096] Due to the first feature as described above, the length of the first interval D1 can be made shorter than that of the conventional technology (technology in which the opening / closing body 30 is opened and closed 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 portion 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. Furthermore, 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 portion 70a can be easily arranged near the door-end side end portion of the opening / closing body 30 regardless of the arrangement positions of the first pulley portion 50a and the second pulley portion 50b. This makes it possible to avoid the remaining dimension LD of the opening 2 from becoming large, and makes it easier to ensure the passage of the opening 2.

[0097] (Configuration - Drive system configuration details - Second feature) Regarding the second feature of the drive system 40, the first pulley portion 50a and the second pulley portion 50b are arranged such that the axial directions of the rotating 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.

[0098] Specifically, as shown in Fig. 3, the first pulley portion 50a and the second pulley portion 50b are arranged such that the axial direction of the rotation shaft 52 of each of the first pulley portion 50a and the second pulley portion 50b is substantially along the vertical direction. The first pulley portion 50a and the second pulley portion 50b are also arranged such 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 to be located above the second pulley portion 50b and to be located above the second connection portion 70b.

[0099] In this case, the pulling portion 80 is disposed so that the portion of the pulling portion 80 extending from the first pulley portion 50a to the second pulley portion 50b is inclined with respect to the left-right direction.

[0100] 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 open / close state of the opening / closing body 30. Specifically, the first connection part 70a is formed of a plate-like body having a substantially U-shaped side surface, and 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 even if the first connection part 70a and the second pulley part 50b overlap when viewed from the planar direction when the opening / closing state of the opening / closing body 30 is switched from the fully closed state to the fully open state. 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.

[0101] This second feature makes it easier to avoid contact between the first pulley portion 50a and the second pulley portion 50b and the first connecting portion 70a or the second connecting portion 70b during opening and closing movement of the opening / closing body 30, thereby ensuring the length of the movement stroke MS of the opening / closing body 30.

[0102] However, this is not limited to the above, and for example, the first pulley portion 50a and the second pulley portion 50b may be arranged so that the axial directions of the rotating shafts 52 of the first pulley portion 50a and the second pulley portion 50b are approximately along the front-to-rear direction, and the first pulley portion 50a and the second pulley portion 50b may be arranged so that they are at different positions from each other in the front-to-rear direction.

[0103] (Configuration - Drive system configuration details - Third feature) As for the third feature of the drive system 40, the first pulley portion 50a and the second pulley portion 50b are disposed at positions corresponding to the opening / closing body 30 in the fully closed state.

[0104] Specifically, as shown in Fig. 3, the first pulley portion 50a and the second pulley portion 50b are disposed so as to be located directly above the opening / closing body 30 in the fully closed state. More specifically, they are disposed in a portion of the interior of the interlock 13 that is located directly above the opening 2 and corresponds to the inspection hatch 13a. In particular, in Fig. 3, the first pulley portion 50a and the second pulley portion 50b are disposed in a position inside the interlock 13 that is 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 closer to the closing direction of the opening 3 than the trailing end of the opening / closing body 30, and the first pulley portion 50a is disposed in a position closer to the closing direction of the opening 3 than the second pulley portion 50b.

[0105] Due to this third feature, for example, when 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 / close state of the opening / closing body 30, making it easier to ensure the maintainability of the drive system 40.

[0106] (Sliding door action) Next, the operation of the automatic door system 1 configured as described above will be described.

[0107] That is, for example, when the drive unit 60 is driven by the control unit of the opening / closing control device 90, the towing unit 80 is sent out in the opening / closing direction via the first pulley unit 50a (specifically, the pulley body 51) by the rotational force of 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 sent-out towing unit 80. Through such a 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.

[0108] 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 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 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 connecting portion 70a, the second connecting 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.

[0109] 4, when the opening / closing body 30 is in a fully open state (or a 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 part of the traction 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.

[0110] (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 pulling portion 80 having one end 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 pulled by the pulling portion 80 is longer than the length of the first interval D1. Therefore, the length of the first interval D1 can be made shorter than that of 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 opening 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, the remaining dimension LD of the opening 2 can be prevented from becoming large, and passability through the opening 2 can be easily ensured.

[0111] 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 on the closing side of the opening 2 relative to 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 on the opening side of the opening 2 relative to 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.

[0112] Furthermore, since the towing portion 80 is positioned so that it winds around the first pulley portion 50a and the second pulley portion 50b while passing through the first connection portion 70a, the first pulley portion 50a, the second pulley portion 50b, and the second connection portion 70b in that order, the length of the first interval D1 can be reliably shortened and the size of the inspection hatch 13a can be reliably reduced.

[0113] Furthermore, 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.

[0114] Furthermore, the first pulley portion 50a and the second pulley portion 50b are arranged so that the axial directions of the rotating shafts 52 of the first pulley portion 50a and the second pulley portion 50b are approximately identical to each other and the first pulley portion 50a and the second pulley portion 50b are at different positions from each other 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.

[0115] Furthermore, 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 maintainable position regardless of the open / closed state of the opening / closing body 30, making it easier to ensure the maintainability of the drive system 40.

[0116] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions described in the claims. Such modifications will be described below.

[0119] (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.

[0120] (About the opening and closing body) In the above embodiment, it has been described that the opening / closing body 30 comprises a guided portion 32, a leading edge door stop portion, and a trailing edge door stop portion 34, but this is not limited to the above, and for example, at least one of the guided portion 32, the leading edge door stop portion, or the trailing edge door stop portion 34 may be omitted.

[0121] (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 on, for example, the surface of the glazed window 13 facing the exterior of the room.

[0122] (About 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.

[0123] (Regarding the 1st and 2nd pulley sections) In the above embodiment, the first pulley portion 50a is described as being disposed above the second pulley portion 50b, but this is not limited thereto. 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.

[0124] In the above embodiment, the first pulley portion 50a and the second pulley portion 50b are described as being disposed in a position corresponding to 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 part of the first pulley portion 50a and the second pulley portion 50b may be disposed in a position not corresponding 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 disposed so as not to be located directly above the opening / closing body 30 in the fully closed state.

[0125] 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 this order.

[0126] In the above embodiment, the first pulley portion 50a is arranged in the vicinity of the indoor side mullion 14 (or the outdoor side mullion 15), and the second pulley portion 50b is arranged in the position between the closed end of the opening 2 and the indoor side mullion 14 (or the outdoor side mullion 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 mullion 14 (or the outdoor side mullion 15), and the second pulley portion 50b may be arranged in the vicinity of the indoor side mullion 14 (or the outdoor side mullion 15). In this case, the pulling portion 80 may be arranged so as to wind 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.

[0127] (About the towing section) In the above embodiment, the traction unit 80 has been described as a belt with ends, but is not limited thereto and may be, for example, a wire with ends or a chain with ends.

[0128] (Regarding the first and second intervals) In the above embodiment, the length of the first interval D1 is described as being set to about half the left-right length CL of the inspection hatch 13a, but this is not limiting and, for example, the length may be set shorter (or longer) than half the left-right length CL of the inspection hatch 13a. In this case, the length of the second interval D2 is set shorter than the length of the second interval D2 in the above embodiment, and the left-right length CL of the inspection hatch 13a may be set shorter than the left-right length CL of the inspection hatch 13a in the above embodiment.

[0129] 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 to this and, for example, it may be set to be shorter than the length of the first interval D1.

[0131] The drive system for an automatic door system of Appendix 2 is the drive system for an automatic door system described in Appendix 1, in which the first pulley means, the second pulley means, the first connection means and the second connection means are arranged so that in a fully closed state in which the opening is fully closed by the opening / closing body, either the first connection means or the second connection means is located on the closing direction side of the opening rather than the first pulley means and the second pulley means, and / or so that in a fully open state in which the opening is fully opened by the opening / closing body, the other of the first connection means or the second connection means is located on the opening direction side of the opening rather than the first pulley means and the second pulley means.

[0132] The drive system for an automatic door system of Appendix 3 is the drive system for an automatic door system of Appendix 1 or 2, wherein the traction means is arranged so that the traction means winds around the first pulley means and the second pulley means while passing through the first connecting means, the first pulley means, the second pulley means, and the second connecting means in that order.

[0133] The drive system for an automatic door system of Supplementary Note 4 is the drive system for an automatic door system of any one of Supplementary Notes 1 to 3, wherein the length of the second gap is longer than the length of the first gap.

[0134] The drive system for an automatic door system of Supplementary Note 5 is the drive system for an automatic door system described in any one of Supplementary Notes 1 to 4, wherein 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.

[0135] The drive system for an automatic door system of Supplementary Note 6 is the drive system for an automatic door system described in any one of Supplementary Notes 1 to 5, wherein the first pulley means and the second pulley means are arranged at positions corresponding to the opening / closing body in a fully closed state in which the opening is fully closed by the opening / closing body.

[0136] The automatic door system of appendix 7 comprises a drive system for an automatic door system according to any one of appendices 1 to 6.

[0137] (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 are 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 connection means and the other end connected to the second connection means, and the first pulley means, the second pulley means, the first connection means, and the second connection 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 made shorter than that of the conventional technology (a technology in which the opening / closing body is moved to open and close with the rotation of a circular 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 made small, 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 prevented from becoming large, making it easier to ensure the passage of the opening.

[0138] According to the drive system for an automatic door device described in Appendix 2, the first pulley means, the second pulley means, the first connecting means and the second connecting means are arranged so that in the fully closed state, either the first connecting means or the second connecting means is located closer to the closing direction of the opening than the first pulley means and the second pulley means, and / or so that in the fully open state, the other of the first connecting means or the second connecting means is located closer to the opening direction of the opening than 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.

[0139] 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 connecting means, the first pulley means, the second pulley means, and the second connecting 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.

[0140] According to the drive system for an automatic door device described in Appendix 4, the length of the second interval is made longer than the length of the first interval. This makes it possible to increase the length of the stroke of the opening / closing body compared to when the length of the second interval is made shorter than the length of the first interval, making it easier to reduce the size of the inspection hatch.

[0141] 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 respective 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 at different positions 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.

[0142] In the drive system for an automatic door device described in Appendix 6, 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 of the 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.
