Description

  The present invention relates to an opening / closing body stop device for an opening / closing device for stopping the closing movement when the opening / closing body that opens and closes contacts an obstacle during the closing movement. For example, a shutter curtain serves as the opening / closing body. It can be used for various opening / closing devices such as shutter devices for combined management and disaster prevention (combined use), awning devices, and smoke-proof hanging wall devices.

  In the management shutter device that is an opening and closing device that is an opening and closing body in which the shutter curtain is opened and closed, the shutter curtain for opening and closing the opening such as the entrance is opened and closed by the operation of the operation device, Stop moving. In addition, in the shutter device for disaster prevention, which is also an open / close device, the shutter curtain having a disaster prevention function such as smoke prevention is closed and moved in the event of an abnormal situation such as a fire. A disaster prevention zone is formed. In such a management shutter device, a shutter device for disaster prevention, and a shutter device for both management and disaster prevention, there is an obstacle in the closing direction of the shutter curtain, and the shutter curtain that is being moved closes against this obstacle. When the contact is made, the closing movement of the shutter curtain is stopped. A shutter curtain stop device for executing this stop is shown in Patent Document 1 and Patent Document 2 below.

  The shutter curtain stopping devices disclosed in these Patent Documents 1 and 2 are arranged on the shutter curtain, and when the shutter curtain that is being closed is in contact with an obstacle, the shutter curtain and the string-like member are machined. A mechanical coupling device for applying tension to the string-like member by its own weight is provided.

JP 2009-13647 A (0027 paragraph, 0028 paragraph, FIG. 1) Japanese Patent Laying-Open No. 2011-185034 (paragraph 0192, FIG. 25)

  By the way, in the shutter curtain stopping device disclosed in Patent Documents 1 and 2 described above, a direction changing device for changing the direction of the string-like member extending in the opening movement direction of the shutter curtain from the mechanical coupling device by 90 degrees is provided. ing.

  However, when the string-like member is changed in direction by 90 degrees, habits are generated in the string-like member, and there is a possibility that the tension does not act on the string-like member quickly. That is, there is a possibility that a loss may occur in the action of tension on the string-like member due to the occurrence of habit in the string-like member.

  For this reason, the device of the direction change apparatus for the tension | tensile_strength to act on a string-like member rapidly is calculated | required.

  An object of the present invention is to provide an opening / closing body stopping device for an opening / closing device in which a tension force acts quickly on a string-like member.

  An opening / closing body stop device for an opening / closing apparatus according to the present invention is disposed on an opening / closing body that can be freely opened and closed, and the opening / closing body and the string-like member are disposed when the opening / closing body that is being closed is in contact with an obstacle. In an opening / closing body stop device of an opening / closing device provided with a mechanical coupling device for causing a tension force to act on the string-like member by its own weight by being mechanically coupled, the opening / closing device from the mechanical coupling device The string-like member extending in the opening movement direction of the body is at a height position above or near the position of the upper side forming member forming the upper side of the opening that is opened and closed by the opening / closing body. The opening / closing body extends in a direction having a component in the opening / closing movement direction.

  In the present invention, the string-like member extending from the mechanical coupling device in the opening movement direction of the opening / closing body is not changed in direction by 90 degrees by the guide roller provided in the direction changing device as in the conventional case. In the height position of the upper side forming member that forms the upper side of the opening that is opened and closed by the opening / closing body, or at a height position that is higher than the position in the vicinity thereof, the opening / closing body is extended in a direction having a component in the opening / closing movement direction. ing.

  That is, in the present invention, since the string-like member is extended in a straighter direction, it is possible to prevent the string-like member from becoming hazy, and to prevent the tension from acting on the string-like member from being lost. Is done.

  For this reason, according to this invention, tension | tensile_strength comes to act on a string-like member rapidly.

  Further, in the present invention, since the conventional direction changing device described above is not required, the number of parts of the opening / closing body stopping device of the opening / closing device can be reduced and the structure can be simplified.

  In the present invention, the string-like member may or may not be inserted and supported by the support member provided on the upper side forming member.

  The shape and structure of the support member may be arbitrary as long as the string-like member is inserted and supported. For example, the support member includes a base attached to the upper side forming member and a thickness direction of the opening / closing body from the base. It may have a protruding piece portion that protrudes in a direction having a component and is provided with a through-hole through which a string-like member can be inserted at the tip or in the vicinity thereof.

  In the present invention, the upper side forming member that is an immovable member may be any member as long as it forms the upper side of the opening that is opened and closed by the opening and closing body. A lintel having a slit through which the shaped member is inserted may be used, or a ceiling member disposed in the vicinity of the lintel.

  As described above, when the support member has the base portion and the projecting piece portion, the projecting piece portion of the support member may extend to the front of the slit, or may extend to the slit. .

  In the former case, when the opening / closing body reaches the fully open position or substantially fully open position, the portion of the string-like member below the through hole of the projecting piece of the support member is angled with the opening / closing movement direction of the opening / closing body. A portion having a first bent portion bent in a direction forming the second bent portion, a second bent portion bent in a direction opposite to the first bent portion, and a horizontal portion or a substantially horizontal portion between the bent portions; It may be made to become. That is, when the opening / closing body reaches the fully open position or the substantially fully open position, the portion of the string-like member that is below the through hole of the projecting piece of the support member is in a direction that forms an angle with the opening / closing movement direction of the opening / closing body. After bending, it may extend in the horizontal direction or substantially horizontal direction, and then bend in the direction opposite to the direction.

  In the former case, that is, when the protruding piece of the support member extends to the front of the slit, the position of the portion of the string-like member extending in the opening movement direction of the opening / closing body from the mechanical coupling device A gap in the thickness direction of the opening / closing body (in other words, a deviation) occurs from the position of the portion supported by the protruding piece portion of the support member.

  For this reason, when the opening / closing body reaches the fully open position or the substantially fully open position, a portion of the string-like member that is lower than the through hole of the projecting piece of the support member may be bent in an S shape. As a result, a large bending wrinkle occurs in a portion of the string-like member below the through hole of the protruding piece of the support member, and there is a possibility that a loss occurs in the action of the tension force on the string-like member.

  However, as described above, when the opening / closing body reaches the fully opened position or the substantially fully opened position, the portion of the string-like member below the through hole of the projecting piece portion of the support member is in the opening / closing movement direction of the opening / closing body. A portion having a first bent portion bent in a direction forming an angle, a second bent portion bent in a direction opposite to the first bent portion, and a horizontal portion or a substantially horizontal portion between the bent portions. By doing so, it is possible to prevent a large bending wrinkle from occurring in a portion of the string-like member that is below the through hole of the protruding piece portion of the support member.

  In addition, as above-mentioned, when the protrusion part part of a supporting member shall extend to the near side of a slit, there exists a possibility that a string-like member may contact the stationary member which is immovable with respect to the opening-closing body which opens and closes. There is. For this reason, you may make it provide the contact prevention member for preventing the contact of a string-shaped member and the immovable member which is immovable with respect to the opening-closing body which moves open / close.

  The shape and structure of the contact prevention member may be arbitrary as long as it can prevent the string-like member from coming into contact with the stationary member. One example of the contact prevention member is the opening / closing body side of the stationary member. It is the roller member arrange | positioned protrudingly.

  In addition, when the upper side forming member is a lintel having a slit through which the opening and closing body and the string-like member are inserted as described above, and the protruding piece portion of the support member extends to the slit, Since there is little possibility that the string-like member comes into contact with the stationary member, it is not necessary to provide a contact preventing member for preventing contact between the string-like member and the stationary member.

  In the present invention described above, the string-like member is slidably inserted into the flexible tubular member, which is disposed at a height position higher than the height position of the upper side forming member or a position in the vicinity thereof, and has flexibility. You may or may not.

  According to the former case, the extending direction of the string-like member is guided by the tubular member, and the string-like part is protected from external force.

  The tubular member may be a member that completely covers the string-like member or a member that does not cover (for example, a mesh-like member).

  An example of the former case is a flexible outer cable.

  In addition, it is preferable that the tubular member not only has flexibility as described above but also has rigidity that does not easily cause bending deformation or the like.

  Moreover, it is preferable that the internal diameter dimension of a tubular member is a little larger than the diameter dimension of a string-like member. That is, the tubular member is preferably configured so that there is almost no difference between the inner diameter dimension of the tubular member and the diameter dimension of the string-like member, and play of the string-like member is rare.

  In addition, it is preferable that the tubular member is coated with a lubricating member or the like on the inner part or the inner part itself is formed with a lubricating member or the like so that the friction with the inserted string-like member is reduced.

  In the present invention described above, a brake device for stopping and moving the opening and closing body by turning on and off, and a slide member that is slidable to switch on and off the brake device are provided. The mechanical coupling device mechanically couples the opening and closing body and the string-like member when the opening and closing body that is being closed is in contact with an obstacle, thereby sliding the slide member on the string-like member to brake the brake device. It is good also as what makes the tension | tensile_strength for turning on turn on by the dead weight of an opening-closing body.

  In the above case, the string-like member may or may not extend to the slide member side.

  Here, “extend to the slide member side” means that the string-like member may be directly connected to the slide member, or the string-like member may be indirectly connected to the slide member via another member. It is.

  In addition, the string-like member extended to the slide member side may be constituted by one string-like member or may be constituted by a plurality of string-like members. That is, one string-like member may be extended to the slide member side, and a plurality of string-like members connected by the connecting member may be extended to the slide member side.

  In the present invention described above, the mechanical coupling device may or may not include a rotating member that is rotated by the string-like member when the opening / closing body is opened and closed.

  In the former case, the string-like member may or may not extend from the rotating member in the opening movement direction of the opening / closing body.

  As described above, the mechanical coupling device includes a rotating member that is rotated by the string-like member when the opening / closing body is opened and closed, and the string-like member extends from the rotating member in the opening movement direction of the opening / closing body. , A take-up reel for winding the string-like member so that the string-like member can be unwound freely. The take-up reel is a first rotating member, and the rotating member that is rotated by the string-like member when the opening / closing member is moved is The second rotary member is spaced apart from the rotary member and has a height position of the uppermost portion lower than the height position of the uppermost portion of the first rotary member, and the string-like member extends from the first rotary member to the second rotary member. You may make it extend in the opening movement direction of an opening-closing body via.

  According to this, the extended position of the string-like member from the rotating member can be made lower.

  The shape, structure, and the like of the second rotating member may be arbitrary as long as the height position of the uppermost portion is lower than the height position of the uppermost portion of the first rotating member. The shape, structure, etc. of the member may be such that the diameter dimension of the second rotating member is smaller than the diameter dimension of the first rotating member, and the height position of the rotation center axis of the second rotating member is set to the first rotating member. These may be made lower than the height position of the rotation center axis of the rotation center, and these may be used together (the diameter dimension of the second rotation member is made smaller than the diameter dimension of the first rotation member and the rotation of the second rotation member). The height position of the center axis may be lower than the height position of the rotation center axis of the first rotating member). In addition, when the shape, structure, etc. of the second rotating member are such that the diameter dimension of the second rotating member is larger than the diameter dimension of the first rotating member, the second rotating member is attached to the second rotating member. It arrange | positions so that the height position of the uppermost part may become lower than the height position of the uppermost part of a 1st rotation member.

  In addition, you may make it extend from the 1st rotation member to the opening movement direction of an opening-closing body, without extending a string-like member via a 2nd rotation member from a 1st rotation member as mentioned above. That is, the second rotating member is not provided, and the rotating member is a take-up reel for winding the string-like member so as to be freely retractable, and the string-like member is extended from the take-up reel in the opening movement direction of the opening / closing body. May be.

  The rotating member may be a guide roller for guiding the string-like member. In this case, the string-like member may be folded back into a U shape or an L shape by a rotating member, or may not be folded back.

  As described above, a brake device for stopping and moving the opening / closing body by turning on and off, and a slide member that is slidable to switch on and off the brake device are provided. In this case, the mechanical coupling device mechanically couples the opening / closing body and the string-like member when the closing movement of the opening / closing body abuts on an obstacle, thereby sliding the slide member on the string-like member. As long as the tension force for turning on the brake device can be applied by the weight of the opening and closing body, it may be of any type and structure.

  An example of the type and structure of this mechanical coupling device is that a plurality of teeth are provided on the outer periphery, a rotating gear (rotating gear) that is rotated by a string-like member when the opening / closing body is moved, and the teeth of the rotating gear The engaging part that can be engaged with the part moves when the closing movement of the opening / closing body comes into contact with the obstacle, and the engaging part is engaged with the tooth part and rotated by this movement. And a lock member that disables rotation of the gear, and the rotation gear is coupled and integrated with the take-up reel that is the first rotation member described above. Another example of the type and structure of the mechanical coupling device is a structure in which a string-like member is clamped by a pair of clamping members such as lever members disposed on an opening / closing body.

  A rotating gear that is rotated by a string-like member when the opening / closing body is moved meshes with a rotating gear that is coupled and integrated with the take-up reel, and an idle gear (idle gear) provided with a plurality of teeth on the outer periphery. But you can.

  Note that the movement performed by the lock member when the opening / closing body that is being closed is in contact with an obstacle can prevent the rotation gear from rotating by the engagement portion of the lock member engaging the tooth portion of the rotation gear. Any movement may be used, and an example of the movement is rotation around an axis, and another example of the movement is a slide movement.

  Note that the take-up reel as the first rotating member may or may not be provided inside the case.

  In the former case, the second rotating member is also provided inside the case where the take-up reel is arranged, and the height position of the upper surface of the case where the second rotating member is arranged is set to the take-up reel. The height of the upper surface of the case where the second rotation member is disposed is formed so that a hole through which the string-like member is inserted to the outside of the case is formed on the upper surface of the case where the second rotating member is disposed. It may be.

  According to this, the feeding position of the string-like member from the take-up reel is the height position of the upper surface of the case where the second rotating member is disposed.

  In the present invention, the string-like member may be a wire, a synthetic resin string, a chain such as a roller chain, or an arbitrary string-like member.

  Furthermore, the brake device according to the present invention may be a single device by itself, or, for example, in combination with an electric motor device for opening and closing the opening and closing body to open and close the opening and closing body. It may be a part of the switch.

  In the present invention, the slide member for switching on and off the brake device described above may be a member constituting an automatic closing device for closing and moving the opening / closing body that has reached the fully open position. Alternatively, it may be a member constituting a device different from the automatic closing device.

  Further, the present invention can be applied to an arbitrary opening / closing device in which an arbitrary opening / closing body is freely movable, and an example of the opening / closing device is a shutter device in which the opening / closing body is a shutter curtain, Further, the present invention can be applied to various opening / closing devices such as an awning device and a smoke-proof hanging wall device.

The shutter curtain 1 is moved up and down by being guided by these guide rails 6 as members.

  A shutter box 8 is disposed in a ceiling space 7 partitioned by the ceiling member 5 with respect to the entrance / exit 2, and this shutter box 8 is shown in FIG. 2, which is a cross-sectional view taken along line S <b> 2-S <b> 2 of FIG. As shown in the figure, it is coupled to a building housing 9 such as a falling wall existing in the ceiling space 7 with a coupler 10 such as a bolt. A take-up shaft 11 is horizontally accommodated in the shutter box 8, and the take-up shaft 11 is rotatably supported by the left and right side portions 8A and 8B shown in FIG. Yes. As shown in FIG. 1, an opening / closing machine 13 is connected to one end of the winding shaft 11 via a driving force transmission means 12 using a sprocket wheel and a roller chain. The opening / closing machine 13 serving as a driving device for driving the winding shaft 11 is also shown in FIG. 2, and the rotational force of the driving shaft 14 of the opening / closing machine 13 is driven by a driving sprocket attached to the driving shaft 14. A driving force transmission means 12 includes a wheel 12A, a driven sprocket wheel 12B attached to the one end of the winding shaft 11, and an endless roller chain 12C bridged between the sprocket wheels 12A and 12B. Then, it is transmitted to the winding shaft 11.

  As shown in FIG. 2, the opening / closing device 13 of the present embodiment is attached to a bracket member 15 coupled to one of the left and right side surface portions 8A and 8B of the shutter box 8. ing.

  As can be seen from FIG. 2, the shutter curtain 1 is wound around the winding shaft 11, and the upper end of the shutter curtain 1 is coupled to the outer peripheral surface of the winding shaft 11. Further, the lower part of the shutter curtain 1 from the winding shaft 11 is suspended below the ceiling member 5 through a slit 17 provided in the lintel 16 disposed on the ceiling member 5, and further the shutter. Both ends in the width direction of the curtain 1 are slidably inserted into the left and right guide rails 6 as described above. The lintel 16 that is a stationary member that is stationary with respect to the shutter curtain 1 and a member that moves together with the shutter curtain 1 (for example, the winding shaft 11, the drive shaft 14 of the opening / closing machine 13, etc.) is disposed to face each other. The lintel members 16A and 16B are formed, and a slit 17 is formed between the lintel members 16A and 16B. The slit 17 is inserted with a shutter curtain 1 and a lock wire 36 which is a string-like member described later. That is, the lintel 16 has a slit 17 through which the shutter curtain 1 and the lock wire 36 are inserted.

  In the present embodiment, the lintel 16 is an upper side forming member that forms the upper side of the entrance 2 that is opened and closed by the shutter curtain 1, and a stationary member that is stationary with respect to the shutter curtain 1 that is opened and closed. It has become.

  FIG. 3 is a cross-sectional view showing the internal structure of the switch 13. As shown in FIG. 3, the switch 13 includes a DC or AC electric motor device 18 and a brake device 19 arranged in parallel in the axial direction, and the drive shaft 14 described above includes an electric motor device. This is a rotating shaft arranged at the center of 18 rotating rotors 18A. A disc-shaped first brake member 20 is coupled to the end of the drive shaft 14 on the brake device 19 side. The brake device 19 is provided with a brake shaft 21 that is slidable by a fixed distance in the axial direction. The brake shaft 21 is coupled to a first brake member 20 and a second brake member 22 that faces in the axial direction. Has been. The brake shaft 21 and the second brake member 22 in the normal state are pressed toward the electric motor device 18 by the spring 23, so that the brake device 19 is pressed by the pressure contact between the first brake member 20 and the second brake member 22. Is on. Accordingly, the drive shaft 14 of the electric motor device 18 at this time is not rotated by the braking force of the brake device 19.

  On the other hand, when the solenoid 24 arranged in the brake device 19 is energized, the brake shaft 21 and the second brake member 22 slide in a direction away from the electric motor device 18 against the spring 23 by the magnetic force of the solenoid 24. To do. For this reason, the press contact between the first brake member 20 and the second brake member 22 is released, and the brake device 19 is turned off. Therefore, at this time, the drive shaft 14 of the electric motor device 18 can be rotated by energizing the coil 25.

  Thus, the brake device 19 is turned off by energization of the solenoid 24. When this energization is stopped, the brake device 19 is turned on. Therefore, the brake device 19 is electrically turned on and off. .

  In the present embodiment, as shown in FIG. 1, an electrical circuit such as a relay circuit or a computer control device 26 is attached to the switch 13, and the control device 26 is an electric motor for the switch 13. The motor device 18 and the brake device 19 are electrically controlled. The control device 26 may be attached to a member, means, device, or the like different from the opening / closing device 13, and the arrangement location thereof is arbitrary.

  Among the left and right building housings 3A and 3B shown in FIG. 1, in one building housing 3A, the shutter curtain 1 is opened and moved upward with respect to the entrance 2 and closed and moved downward. An operation device 30 is attached to cause the operation to be performed. The operation device 30 is provided with an “open” button, a “close” button, and a “stop” button. Further, the shutter curtain 1 occupies most of the area of the shutter curtain 1, and a curtain body 1A whose upper end is coupled to the winding shaft 11 and a seat plate 1B provided at the lower end of the curtain body 1A. And has. The curtain body 1A of the present embodiment is formed by connecting a large number of slats vertically.

  The curtain main body 1A is an opening / closing body main body in the present embodiment, and the seat plate 1B is an end member in the present embodiment. Further, the seat plate 1B forms an end portion on the closing side of the shutter curtain 1 in the present embodiment.

  When the shutter curtain 1 reaches the height position of the lintel 16 disposed on the ceiling member 5 as described above, or when the occupant plate 1B has the lintel 16 and the floor 4 as shown in FIG. When the shutter button 1 of the operating device 30 is operated when the shutter curtain 1 that has reached the halfway position is in the half-closed state (half-open state), the control device 26 receives a signal from the “close” button. Since the solenoid 24 of the brake device 19 is energized by this control, the brake device 19 is turned off. Thus, the shutter curtain 1 is rotated downward from the take-up shaft 11 by rotating the take-up shaft 11 and the drive shaft 14 by the dead weight of the shutter curtain 1, and the shutter curtain 1 that is closed and moved thereby is brought into the fully closed position. When it reaches, the control of the control device 26 to which a signal from a sensor (not shown) that detects the fully closed position is input, the energization to the solenoid 24 is cut off, and the brake device 19 is turned on by the spring 23. In addition, when the shutter curtain 1 is fully closed, or the shutter curtain 1 is in a half-open state where the seat plate 1B reaches the midway position between the lintel 16 and the floor 4 as shown in FIG. When the “open” button is operated in a half-closed state), the solenoid 24 of the brake device 19 is energized under the control of the control device 26 to which a signal from the “open” button is input. While being turned off, the coil 25 of the electric motor device 18 is energized under the control of the control device 26. For this reason, the drive shaft 14 rotates in the reverse direction, and this rotation is transmitted to the winding shaft 11 via the driving force transmission means 12 described above, and the shutter curtain 1 moves to the winding shaft 11 by the reverse rotation of the winding shaft 11. It is rolled up and moved. When the shutter curtain 1 reaches the fully open position, the energization to the solenoid 24 is cut off and the brake device 19 is turned on by the spring 23 under the control of the control device 26 that receives a signal from a sensor (not shown) that detects the fully open position. At the same time, the power to the coil 25 is cut off by the control of the control device 26.

  Further, when the “stop” button is operated while the shutter curtain 1 is being closed and moved, the energization of the solenoid 24 is cut off by the control of the control device 26 to which a signal from the “stop” button is input. When the brake device 19 is turned on by the spring 23, the shutter curtain 1 stops at that position. Further, when the “stop” button is operated while the shutter curtain 1 is being opened and moved, the energization to the solenoid 24 is cut off by the control of the control device 26 to which a signal from the “stop” button is input. The brake device 19 is turned on by the spring 23, and energization of the coil 25 of the electric motor device 18 is interrupted by the control of the control device 26, whereby the shutter curtain 1 stops at that position.

  Next, the operation of the shutter device according to the present embodiment will be described.

  In the building where the shutter device according to the present embodiment is installed, when a disaster such as a fire occurs when the shutter curtain 1 is stopped at the fully open position or in the middle of the opening and closing movement direction, the sensor from the sensor that has detected this disaster The automatic closing shown in FIG. 14 (B) by the control of an electric circuit such as a relay circuit (not shown) to which a signal is input or a control device by a computer (this control device may also serve as the control device 26 in FIG. 1). Since the solenoid 126 of the device 32 is energized and the solenoid 126 is energized, the plunger 127 of the solenoid 126 moves backward against the spring force of the spring 128. Accordingly, the bending lever member 129 having one end abutting against the above-described tip member 140 is opposite to the K direction in FIG. 14B around the central axis 129A against the spring force of the spring 131. It will rotate in the L direction. The state at this time is shown in FIG. When the bending lever member 129 rotates in the L direction about the central axis 129A, the roller 130 of the bending lever member 129 escapes from the concave portion 120B of the first slide member 120, so that the first slide member 120 has the spring force of the spring 121. The forward movement is stopped when the front end of the connecting member 138 provided on the first slide member 120 abuts on the above-described rising portion 110 </ b> B of the machine frame 110. That is, the connecting member 138 of the present embodiment is also an advance limit defining portion in the first slide member 120 for defining the advance limit of the first slide member 120.

  Further, the position of the front end of the first slide member 120 at this time is as shown in FIG. 15B among the three positions H, I, and J shown in FIGS. 13 and 14B. And the I position which is the foremost position.

  Further, when the first slide member 120 advances as described above, the actuator 136 of the first electric switch 135 is disengaged from the dog member 137 attached to the first slide member 120. In response to the generated signal, the control device described above stops energization of the solenoid 126.

  When the energization of the solenoid 126 is stopped, the plunger 127 protrudes from the solenoid 126 by the spring force of the spring 128, and the bending lever member 129 is centered on the central axis 129A by the spring force of the spring 131. Rotate in the direction. Since the first slide member 120 at this time has advanced to the movement limit where the front end of the first slide member 120 reaches the I position, the roller 130 of the bending lever member 129 is shown in FIG. As described above, it hits the aforementioned inclined surface 120 </ b> C of the first slide member 120. For this reason, the rotation of the bending lever member 129 about the central axis 129A in the K direction stops halfway.

  When the first slide member 120 moves forward as described above, the operation member 122 of FIG. 3 provided at the front end of the first slide member 120 is connected to the lever member 31 of the switch 13 via the operated member 123. The first portion 31A is pressed in the direction A in FIG. For this reason, as described above, the first portion 31A swings in the A direction with the second bent portion 31D of the lever member 31 as a fulcrum, so that the brake shaft 21 and the second brake of the brake device 19 of the opening / closing machine 13 are provided. The member 22 slides in the A ′ direction, which is the same direction as the A direction, so that the brake device 19 that has been turned on until then is turned off. For this reason, the shutter curtain 1 that has been stopped halfway in the opening / closing movement direction is directed downward while rotating the take-up shaft 11 by the weight of the seat plate 1B and the like below the take-up shaft 11. The above-described drive shaft 14 of the opening / closing machine 13 is also freely rotated via the drive force transmission means 12 and the shutter curtain 1 is fully closed, so that a disaster prevention zone is formed by the shutter curtain 1. Will be.

  Further, when a person discovers that a disaster such as a fire has occurred, this person is arranged in the operating device 30 shown in FIG. 1 and is connected to the end of the second control wire 112 described above. The second control wire 112 is pulled by a manual operation member such as a lever member. As described with reference to FIG. 14B, the other end of the second control wire 112 is connected to the above-described tilting member 141, so that the second control wire 112 is pulled. The tilting member 141 is tilted and rotated around the central shaft 142A toward the solenoid 126, and the tip member 140 and the plunger 127 are retracted by the pressing action of the tilting member 141. As a result, even before the solenoid 126 is energized and excited, the bending lever member 129 is moved through the tip member 140 by the pressing force from the raising / lowering member 141 as when the solenoid 126 is energized and excited. 14B, the roller 130 of the bending lever member 129 escapes from the recess 120B of the first slide member 120, and the first slide member 120 moves to the spring 121. It will move forward with spring force.

  For this reason, the shutter curtain 1 is also fully closed by operating a manual operation member such as a lever member connected to the end of the second control wire 112, and a disaster prevention zone is formed by the shutter curtain 1. Can do.

  As described above, when the first slide member 120 moves to the forward limit, the connecting portion 138A provided on the connecting member 138 of the first slide member 120 is shown in FIGS. 15 (A) and 16 (A). As shown in FIG. 6, the second slide member 210 abuts on the step surface 210B or approaches the step surface 210B. Therefore, even if the first slide member 120 moves to the forward limit shown in FIGS. 15B and 16B, the second slide member 210 is shown in FIGS. 15A and 16A. As shown, it remains stopped at the position shown in FIG. Therefore, the second slide member 210 is configured as a constituent member, and the intermediate device 200 shown in FIGS. 15A and 16A maintains the same state as in FIG. 14A. To do.

  As described above, when the shutter curtain 1 reaches the fully closed position and a disaster such as a fire is resolved, the shutter curtain 1 is disposed on the operation device 30 and connected to the end of the third control wire 113 described above. The third control wire 113 is pulled by a manual operation member such as a lever member. Accordingly, since the third control wire 113 is connected to the connecting portion 138A of the connecting member 138 of the first slide member 120, the first slide member 120 moves backward against the spring force of the spring 121. become. For this reason, the first slide member 120 returns from the position shown in FIG. 16B to the initial position where the front end of the first slide member 120 is at the H position in FIGS. 13 and 14B. It will be. Further, when the first slide member 120 returns to this initial position, the bending lever member 129 rotates in the K direction in FIG. 14B by the spring force of the spring 131 about the central axis 129A. The roller 130 of the member 129 is fitted into the recess 120 </ b> B of the first slide member 120, so that the first slide member 120 on which the spring force of the spring 121 is acting acts on the front end of the first slide member 120. Reaches the H position and stops. Thereby, the automatic closing device 32 returns to the initial state before the occurrence of a disaster such as a fire.

  When the third control wire 113 is pulled by a manual operation member such as a lever member as described above, the connection portion 138A of the connection member 138 is brought into contact with the bracket 203 shown in FIG. As a result, when the third control wire 113 is pulled with an excessive operating force by a manual operation member such as a lever member, the bracket indicates that the excessive operating force acts on the connecting member 138 and the first slide member 120. You may make it prevent by 203.

  When the first slide member 120 returns to the initial position as described above, the brake shaft 21 and the second brake member 22 of the brake device 19 of the opening / closing machine 13 are moved in the direction opposite to the A ′ direction by the spring 23 described above in FIG. In order to move, the brake device 19 returns from off to on. Thereafter, by operating the above-mentioned “open” button provided in the operating device 30, the shutter curtain 1 opens and moves to the fully open position as described above.

  As described above, the occurrence of a disaster such as a fire is detected by the above-described sensor, or the person who discovers the occurrence of a disaster such as a fire pulls the second control wire 112, so that the shutter curtain 1 becomes a disaster prevention section. When the shutter device moves to the fully closed position to form the shutter, the shutter device according to the present embodiment is the above-described shutter device for disaster prevention. On the other hand, as described above, when the opening / closing movement and stoppage of the shutter curtain 1 are performed by operating the “open”, “closed”, and “stop” buttons of the operation device 30, the present embodiment is used. This is when the shutter device is the aforementioned management shutter device.

  When the shutter device according to the present embodiment becomes a disaster prevention shutter device and the shutter curtain 1 is closed and moved, in other words, the automatic closing device 32 is in the state shown in FIG. 16A is in the state shown in FIG. 16A, and when the shutter curtain 1 is closing and moving, there is an obstacle 34 shown in FIG. 1 below the shutter curtain 1 in the closing movement direction. When the shutter curtain 1 is in the middle of the closing movement, the curtain sub-portion 71B disposed at the front end of the shutter curtain 1 on the closing side, in other words, the lower portion of the seat plate 1B of the shutter curtain 1 4 that forms FIG. 4 comes into contact with the obstacle 34, and the lowering of the movable portion 70B stops.

  Even if the lowering of the movable portion 70B stops, the curtain main portion 71A configured by the curtain main body 1A and the fixed portion 70A of FIG. 4 of the seat plate 1B is lowered from the state of FIG. As a result of the relative rise of the curtain sub-part 71B (movable part 70B) with respect to the curtain main part 71A generated by this lowering, as shown in FIG. It swings upward about the fulcrum shaft 80. Accordingly, the lock member 50 constituting the mechanical coupling device 55 described above is rotated in the N direction of FIG. 7 by the pressing member 54 provided on the swinging member 81 to be in the state of FIG. The engaging portion 53 of the lock member 50 engages with the tooth portion 35 </ b> A of the rotating gear 35.

  Accordingly, the rotary gear 35 and the take-up reel 37 that have been rotated in the S direction in FIG. 7 when the shutter curtain 1 is closed and moved cannot be rotated in this S direction. The reel 37 becomes non-rotatable, and the shutter curtain 1 and the lock wire 36 fed out from the take-up reel 37 are coupled by the mechanical coupling device 55 having the rotary gear 35 and the lock member 50 as components. become. Therefore, a downward tension force due to the weight of the shutter curtain 1 excluding the movable portion 70B, that is, the weight of the curtain main portion 71A, acts on the lock wire 36.

  After the shutter curtain 1 that is closing and moving is in contact with the obstacle 34 as described above, downward tension due to the weight of the shutter curtain 1 excluding the movable portion 70B acts on the lock wire 36. When the obstacle 34 is dented and deformed, the lock wire 36 coupled to the shutter curtain 1 by the mechanical coupling device 55 is pulled downward by the amount of the dented deformation.

  Further, even if the obstacle 34 is a hard object that does not dent or deform hardly, when the lock member 50 is rotated in the N direction of FIG. 7 by the pressing member 54 of the swing member 81, it is shown in FIG. As described above, of the first engaging portion 53A, the second engaging portion 53B, and the third engaging portion 53C provided as the engaging portion 53 on the lock member 50, the first engaging portion 53A is first rotated. The gear 35 is engaged with the tooth portion 35 </ b> A, and then the second engagement portion 53 </ b> B and the third engagement portion 53 </ b> C are engaged with the tooth portion 35 </ b> A of the rotary gear 35. Of these engagements, at least the engagement of the first engagement portion 53A with the tooth portion 35A is separated from the lock member 50 in the length direction of the lock member 50, as shown in FIG. Of the first lock member side contact portion 59A and the second lock member side contact portion 59B that are provided as the two lock member side contact portions 59, a shaft 56 serving as a rotation center axis of the lock member 50 The first lock member-side contact portion 59A located far from the center is pushed up by the pressing member 54 serving as the shutter curtain-side contact portion 58.

  The interval between the first engagement portion 53A, the second engagement portion 53B, and the third engagement portion 53C is the interval dimension (tooth pitch) between the tooth portions 35A that are formed on the rotary gear 35 at regular intervals. The same dimension or substantially the same dimension, or a dimension that is an integral multiple of 2 or more or a dimension that is approximately an integral multiple of the spacing dimension between the tooth portions 35A. For this reason, when the first engaging portion 53A is engaged with the tooth portion 35A, the second engaging portion 53B and the third engaging portion 53C are also engaged with the tooth portion 35A.

  When the first lock member side contact portion 59A is pushed up by the pressing member 54 as described above, next, as shown in FIG. 8, the second lock member side contact portion 59B of the lock member 50 is used. Comes into contact with the pressing member 54, and the second lock member side contact portion 59B is pushed up. That is, the push-up member 54 pushes up the lock member side contact portion 59 of the lock member 50 from the first lock member side contact portion 59A to the second lock member side contact portion 59B. This push will be done.

  Therefore, the rotation of the lock member 50 in the N direction shown in FIG. 7 is continued in two stages, whereby the first engagement portion 53A of the lock member 50 is rotated by the rotation gear. The second engagement portion 53B and the third engagement portion 53C continue to engage with the tooth portion 35A of the rotary gear 35 even when the engagement with the tooth portion 35A of the 35 is disengaged, and these second engagement portions 53B and the third engaging portion 53C slightly rotate the rotating gear 35 in the T direction in FIG. The rotation in the T direction is a rotation in a direction in which the take-up reel 37 winds the lock wire 36 and is a direction in which the lock wire 36 is pulled downward.

  In this way, the second engagement portion 53B and the third engagement portion 53C rotate the rotation gear 35 in the T direction because the distance from the shaft 56 that is the rotation center of the lock member 50 is the first. Since the second lock member side contact portion 59B shorter than the first lock member side contact portion 59A is pushed up by the pressing member 54, the rotation gear 35 by the second engagement portion 53B and the third engagement portion 53C. The amount of rotation increases in the T direction. Therefore, when the obstacle 34 is indented and deformed even if the amount of relative rise of the curtain sub-portion 71B with respect to the curtain main portion 71A when the shutter curtain 1 being closed is in contact with the obstacle 34 is constant. In the same manner as described above, it is possible to secure a sufficient amount of downward pulling of the locking wire 36.

  For this reason, even when the obstacle 34 is a hard thing which does not dent-deform and hardly deforms, when the obstacle 34 dents and deforms the locking wire 36 coupled to the shutter curtain 1 by the mechanical coupling device 55. Can be pulled down sufficiently.

  In the present embodiment, the number of the engaging portions 53 provided on the lock member 50 is three, but the number may be four or more.

  Further, when the shutter curtain 1 comes into contact with the obstacle 34, the first lock member side contact portion 59A of the lock member 50 is pushed up by the pressing member 54 that is the shutter curtain side contact portion 58 as described above, Accordingly, the first engagement portion 53A of the lock member 50 that rotates in the N direction about the shaft 56 of FIG. 7 tries to engage with the tooth portion 35A of the rotation gear 35. Or the rotation timing of the rotation gear 35 causes the tip of the first engaging portion 53A and the tip of the tooth portion 35A to come into contact with each other, so that the lock member 50 and the rotation gear 35 are brought into contact with each other. In other words, the lock member 50 and the rotation gear 35 may be in a deadlock state.

  However, in the present embodiment, as described with reference to FIG. 9, the lock member 50 and the shaft 56 serving as the rotation center axis of the lock member 50 are rotated by the long hole 67 formed in the case 33 described above. Since it is movable toward and away from the gear 35 and is always biased in the X direction on the rotating gear 35 side by the elastic biasing force of the torsion coil spring 57 that is an elastic member, When the deadlock state occurs, the lock member 50 and the shaft 56 are slightly moved in the direction of retreating from the rotation gear 35 due to the reaction force from the rotation gear 35 to eliminate the deadlock state, and torsion coil springs. The first urging portion 53A of the lock member 50 is engaged with the tooth portion 35A of the rotating gear 35 that continues to rotate. It made.

  For this reason, according to the present embodiment, the tip of the first engagement portion 53A of the lock member 50 and the tip of the tooth portion 35A of the rotation gear 35 come into contact with each other, and the lock member 50 and the rotation gear 35 enter a deadlock state. Thus, an excessive load generated on the lock member 50 or the like when this deadlock state occurs can be eliminated.

  Further, in the present embodiment, since the first lock member side contact portion 59A provided on the lock member 50 is an elastic portion by the leaf spring 60, the above-described deadlock state occurs. Because the elastic portion is elastically deformed by the reaction force from the rotating gear 35, the lock member 50 is rotated in the M direction in FIG. This can also eliminate the deadlock state.

  As described above, when the shutter curtain 1 in the closing movement is brought into contact with the obstacle 34 and the locking wire 36 is pulled downward, the other end of the locking wire 36 is, as described above, shown in FIG. Since the first rotation member 201 is connected to the first rotation member 201 which is a constituent member of the intermediate device 200 in the state of A), the first rotation member 201 rotates in the direction C in FIG. As a result of this rotation, the second rotation member 202 in which the convex portion 208 is in contact with the side surface 201D of the cam portion 201C of the first rotation member 201 is rotated in the G direction in FIG. As a result, the second slide member 210 in which the convex portion 211 of the second rotating member 202 is inserted into the opening hole 210 </ b> A is caused by the pressing force from the convex portion 211 as shown in FIG. Retreats against the spring force of the spring 212.

  Accordingly, the second slide member 210 presses the connecting portion 138A of the connecting member 138 of the first slide member 120 by the step surface 210B. For this reason, the first slide member 120 also moves backward, The aforementioned brake device 19 is switched from off to on. Therefore, the shutter curtain 1 that is in contact with the obstacle 34 in FIG. 1 during the closing movement stops the closing movement. The state of the automatic closing device 32 at this time is shown in FIG. 17B, and the position of the front end of the first slide member 120 at this time is the J position shown in FIGS.

  Further, as described above, when the locking wire 36 is pulled, the stepped surface 210B of the second slide member 210 that moves backward presses the connecting portion 138A of the connecting member 138 of the first slide member 120, thereby causing the first slide. Since the member 120 moves backward, the step surface 210B serves as a pressing portion of the second slide member 210 for pressing the first slide member 120, and the connecting portion 138A receives the pressing force from the second slide member 210. It is a pressed portion of the first slide member 120 for receiving.

  In the above operation, as described above, when the second rotating member 202 is rotated in the G direction in FIG. 14A, the pinion gear 300B of the delay device 300 rotates in the E direction. When the pinion gear 300B rotates, the one-way clutch disengaging function of the delay device 300 functions as described above. Therefore, the pinion gear 300B rotates at high speed in the E direction, and the second rotating member 202 also moves in the G direction. It can rotate at high speed. In other words, no delay action occurs in the delay device 300 at this time.

  Further, when the locking wire 36 is pulled as described above, the first rotating member 201 rotates in the C direction in FIG. 14A and the second rotating member 202 rotates in the G direction. In addition, since the movements performed by the first rotation member 201 and the second rotation member 202 are rotation movements, the first rotation is performed even if the length of the lock wire 36 is increased. The entire rotation amount of the member 201 is not transmitted to the second rotation member 202.

  In other words, in the present embodiment, as described above, the locking member 50 is provided with the three engagement portions 553A, 53B, in consideration of the case where the obstacle 34 is a hard member that does not dent and is not deformed. 53C is provided, and even if the length by which the locking wire 36 is pulled by the action of the engaging portions 53A, 53B, and 53C is increased, the first rotation of the total rotation amount of the first rotation member 201 Only when the side surface 201D of the cam portion 201C of the member 201 is in contact with the convex portion 208 of the second rotating member 202, the rotation of the first rotating member 201 in the C direction is changed to the second rotating member 202. This is transmitted as the rotation of the second rotating member 202 in the G direction. Even if the first rotating member 201 rotates in the C direction after the side surface 201D of the cam portion 201C of the first rotating member 201 does not contact the convex portion 208 of the second rotating member 202, In other words, the rotation is an idling rotation, and the second rotating member 202 is stopped when the first rotating member 201 performs the idling rotation.

  For this reason, even if the length by which the lock wire 36 is pulled is long and the rotation amount of the first rotation member 201 is large, the distance by which the first slide member 120 moves backward is not increased. FIG. 17B shows the position at which the first slide member 120 moves backward when the shutter curtain 1 in the closed movement comes into contact with the obstacle 34. The front end of the first slide member 120 is shown in FIG. As described above, among the three positions I, J, and H shown in FIGS. 13 and 14B, the position reaches the J position. This J position is a position in front of the H position which is the initial position, and is a position where the brake device 19 can be mechanically switched from off to on by the first slide member 120. FIG. The roller 130 of the bending lever member 129 indicated by () is a position where the roller 130 is in a state of being escaped from the concave portion 120B of the first slide member 120, as in FIG. The fact that the roller 130 is in a state of being escaped from the recess 120B in this manner is shown in FIG. 17B, which shows the time when the shutter curtain 1 in the closed movement is in contact with the obstacle 34. ing.

  As can be understood from the above description, after the shutter curtain 1 is closed and started to move due to the occurrence of a fire or the like, the shutter device according to the present embodiment is installed due to a fire or other reasons. Even if the building has a power failure, when the shutter curtain 1 is in contact with the obstacle 34 during the closing movement, the first slide member 120 of the automatic closing device 32 switches the brake device 19 of the switch 13 from off to on. Thus, the shutter curtain 1 can be mechanically stopped without using electricity. The mechanical coupling device 55 mechanically couples the shutter curtain 1 and the locking wire 36 to the locking wire 36 when the closing shutter curtain 1 contacts the obstacle 34. The tension force for sliding the first slide member 120 to turn on the brake device 19 is applied by the dead weight of the shutter curtain 1.

  As described above, after the brake device 19 is switched from OFF to ON, and the obstacle curtain 34 is removed after the closing shutter curtain 1 stops, the curtain sub-portion 71B of the shutter curtain 1 is moved. Since it moves down, the mechanical coupling device 55 releases the coupling between the shutter curtain 1 and the locking wire 36. As a result, the tension force acting on the locking wire 36 disappears, so the first rotating member 201 rotates in the direction B in FIG. 14A with the spring 205, and the second rotating member 202. When the second slide member 210 is advanced by the spring 212, the second slide member 210 is rotated in the direction F in FIG. 14A, and when the second slide member 210 is advanced, the first slide member 120 of the automatic closing device 32 is moved. Is advanced by the spring force of the spring 121 such that the position of the front end shifts from the J position in FIG. 17B to the I position shown in FIGS. 13 and 14B. For this reason, the brake device 19 of the opening / closing machine 13 is mechanically switched again from on to off, and the shutter curtain 1 is closed and restarted.

  At this time, the second rotation member 202 rotates in the F direction in FIG. 14A, whereby the pinion gear 300B of the delay device 300 rotates in the D direction, and the pinion gear 300B moves in the D direction. Regarding the rotation, as described above, a resistance force due to the viscous fluid is generated in the delay device 300 which is a rotary damper. For this reason, the position of the front end of the first slide member 120 shifts from the J position in FIG. 17B to the I position in FIGS. 13 and 14B, and this shift causes the brake device 19 of the switch 13 to move. The switching from ON to OFF is not performed instantaneously due to the delay action of the delay device 300, and this switching time is delayed. Therefore, when the shutter curtain 1 is closed and restarted by the removal of the obstacle 34, the movement of the obstacle 34 is started with a time delay from the removal of the obstacle 34. It can be carried out.

  In the above, the distance by which the first slide member 120 moves backward when the shutter curtain 1 that is being closed is in contact with the obstacle 34 is such that the front end of the first slide member 120 is located behind the J position. When the distance is long, the roller 130 of the bending lever member 129 is fitted into the concave portion 120 </ b> B of the first slide member 120. When such a situation occurs, even if the obstacle 34 with which the shutter curtain 1 that is moving in contact is removed is removed, the first slide member 120 is moved to the brake device 19 by the stopper action of the roller 130. Cannot be advanced to reach the I position where it can be switched from on to off.

  That is, the operable range of the first slide member 120 of the automatic closing device 32 that is a switching member that switches the brake device 19 on and off includes a range in which the brake device 19 cannot be switched from on to off. Will be.

  However, according to this embodiment, as is apparent from the above, the first rotating member 201 serving as the abutting member on the locking wire 36 side and the first sliding member 120 side of the automatic closing device 32 are provided. Since the second rotating member 202 that is a contacted member is a member that rotates about the central axes 201A and 202A, a part of the total amount of rotation of the first rotating member 201. Therefore, the distance by which the first slide member 120 moves backward when the shutter curtain 1 being moved in contact with the obstacle 34 is as follows: The front end of the first slide member 120 is not a long distance that is a position on the rear side of the J position. For this reason, the first slide member 120 can be stopped at a retreat distance in which the position of the front end is the J position. Thus, after the obstacle 34 with which the shutter curtain 1 moving in contact is removed is removed, The brake device 19 can be switched from on to off.

  For this reason, according to the present embodiment, the first rotation member 201, the second rotation member 202, and the like constitute the operation range limiting means 230 that does not operate the first slide member 120 to the above-described non-switchable range. It will be.

  In the present embodiment, the lock member 50 which is a constituent member of the mechanical coupling device 55 shown in FIGS. 7 and 8 includes the engaging portion of the lock member 50 as described in FIG. Since the clearance adjustment means 66 for adjusting the magnitude | size of the clearance gap 65 between the front-end | tip of 53 and the front-end | tip of the tooth | gear part 35A of the rotation gear 35 is provided, the shutter curtain 1 is not contact | abutting to an obstruction. In normal times, the size of the gap 65 can be set to an appropriate value. For this reason, a problem that occurs when the size of the gap 65 is larger than the appropriate value, that is, when the shutter curtain 1 that is moving in close contact with the obstacle 34, the lock member 50 is immediately engaged. Since the portion 53 does not engage with the tooth portion 35A of the rotating gear 35, it is possible to solve the problem that it becomes difficult to stop the shutter curtain 1 instantaneously because obstacle detection is delayed. A problem that occurs when the size of the gap 65 is smaller than an appropriate value, that is, when the shutter curtain 1 is not in contact with the obstacle 34, for example, when the rotary gear 35 or the lock member 50 vibrates. The problem that the engaging portion 53 comes into contact with or engages with the tooth portion 35A can be solved.

  The above description has been made when the shutter device according to the present embodiment is the above-described shutter device for disaster prevention. When this shutter device is the aforementioned management shutter device, that is, when the shutter curtain 1 is closed and moved by the operation of the aforementioned operation device 30, the shutter curtain 1 contacts the obstacle 34. Sometimes, since the tension force and the pulling force act on the locking wire 36, the first rotating member 201 of the intermediate device 200 rotates in the direction C in FIG. Although the second slide member 210 moves backward via the two rotation member 202, the first slide member 120 at this time has moved backward to the backward limit where the position of the front end is the H position. As shown in A), there is a large gap between the step surface 210B of the second slide member 210 and the connecting portion 138A of the connecting member 138 of the first slide member 120. Even ride member 210 is retracted, the retraction does not affect the first slide member 120.

  In other words, when the shutter device according to the present embodiment is a management shutter device, the first slide member 120 becomes a constituent member even if the shutter curtain 1 that is being closed is in contact with the obstacle 34. The automatic closing device 32 is not activated, and the automatic closing device 32 maintains the state shown in FIG.

  In this embodiment, when the shutter device is a management shutter device, the shutter curtain 1 that is closing and moving is in contact with an obstacle, and the tension force or the pulling force of the lock wire 36 causes the intermediate device 200 to move. When the first rotating member 201 of the first rotating member 201 rotates in the C direction, the actuator 221 of the second electric switch 220 described above operates to disengage from the dock member 222 of the first rotating member 201. 1 controls the electric motor device 18 and the brake device 19 of the switch 13 electrically by the control device 26 shown in FIG. 1 so that the shutter curtain 1 has a predetermined height from the position where it comes into contact with the obstacle. The reversal ascending to move to the position and stop. That is, after the shutter curtain 1 of the management shutter device is brought into contact with the obstacle, the shutter curtain 1 opens and moves to a height position away from the obstacle and stops.

  As described above, in this embodiment, the brake device 19 for stopping and moving the shutter curtain 1 by turning on and off, and the slide device 19 can be slid to switch the brake device 19 on and off. The mechanical coupling device 55 mechanically couples the shutter curtain 1 and the locking wire 36 when the shutter curtain 1 being closed is in contact with the obstacle 34. The tension force for sliding the slide member 120 to turn on the brake device 19 is applied to the lock wire 36 by the weight of the shutter curtain 1.

  The mechanical coupling device 55 includes a guide roller 29 that is a rotating member that is rotated by the lock wire 36 when the shutter curtain 1 is opened and closed. The lock wire 36 opens the shutter curtain 1 from the guide roller 29. It extends in the moving direction.

  Further, the mechanical coupling device 55 has a take-up reel 37 for taking up the lock wire 36 so as to be unwound, and the take-up reel 37 is a first rotating member, and the guide roller 29 is a take-up reel. 37, and the uppermost height position 29 </ b> B is a second rotating member lower than the uppermost height position 37 </ b> B of the take-up reel 37, and the lock wire 36 extends from the take-up reel 37. The shutter curtain 1 extends in the opening movement direction via the guide roller 29.

  Further, the mechanical coupling device 55 is provided with a plurality of tooth portions 35 </ b> A on the outer peripheral portion, and the rotation gear 35 that is rotated by the lock wire 36 when the shutter curtain 1 is moved, and the tooth portions 35 </ b> A of the rotation gear 35. An engaging portion 53 that can be engaged is provided, and moves when the shutter curtain 1 that is being closed is in contact with the obstacle 34. By this movement, the engaging portion 53 engages with the tooth portion 35A. And a lock member 50 that prevents the rotation gear 35 from rotating. The rotation gear 35 is coupled and integrated with the take-up reel 37.

  In the present embodiment described above, the locking wire 36 extending in the opening movement direction of the shutter curtain 1 from the mechanical coupling device 55 is rotated 90 degrees by the guide roller provided in the direction changing device as in the prior art. Without being converted, the shutter curtain 1 extends in a direction having a component in the opening / closing movement direction at the height position of the lintel 16 or a position higher than the vicinity thereof.

  That is, in the present embodiment described above, since the locking wire 36 is extended in a straighter direction, it is possible to prevent the lock wire 36 from generating habit, and to exert the tension on the locking wire 36. Loss is prevented from occurring.
