Description

Technical Field

[0001] The present invention relates to the structure of an opening / closing body device.

Background Art

[0002] A shutter device is disposed outside a sash or the like at a building opening such as a house. The shutter device serves the purpose of crime prevention and also prevents strong winds and heavy rains such as typhoons. There is known a shutter device in which slats constituting a shutter curtain are difficult to come off from a guide rail when a flying object collides with it in a strong wind such as a typhoon (see Patent Document 1). This shutter device includes a shutter curtain including a plurality of slats connected in the vertical direction, a guide rail having a recess for receiving a lateral end of the shutter curtain, and a shaft for winding and unwinding the shutter curtain. The shutter curtain can take a wind-resistant state in which the shutter curtain is extended from the fully closed state. In the wind-resistant state, the shutter curtain contacts both the indoor-side inner wall and the outdoor-side inner wall of the recess of the guide rail.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the shutter device of Patent Document 1 is in a state where the shutter curtain is extended more than the fully closed state in the wind-resistant state. In this wind-resistant state, a plurality of slats form a wavy or zigzag shape extending in the vertical direction. As a result, the bending rigidity of the shutter curtain is increased, making it difficult for the shutter curtain to deform when an object flies and collides, and suppressing the slats from coming off. However, internal stress in the compression direction accumulates in each slat. In this case, if the weight and speed of a certain degree of flying object are such that the internal stress in the compression direction acts in a direction that promotes the deformation (bending) of the slat that reaches the glass from somewhere, as a result, it is feared that the impact will be transmitted from the bent slat to the glass window and the glass will break. In addition, in a normal shutter curtain without the above countermeasures, as described above, although the shutter curtain is in a closed state, there is still a clearance and play between the slats, and there is still looseness in the indoor and outdoor directions. If an object flies and collides in this state, the slats will easily deform and damage the glass window.

[0005] The present invention has been made in view of the above situation, and an object thereof is to provide a structure of an opening / closing body device that makes it difficult for the glass of the sash frame inside the shutter to break when an object flies and collides with the window shutter.

Means for Solving the Problems

[0006] Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments. The structure of the opening / closing body device according to claim 1 of the present invention includes an opening / closing body 15 provided on the outdoor side of a glass window 41 of an opening 11 of a building to open and close the opening 11, a pair of parallel guide rails 16 disposed across the opening 11 to guide both sides orthogonal to the opening / closing direction of the opening / closing body 15, a drive unit 17 that opens and closes the opening / closing body 15, and a locking unit 19 that locks the leading end of the extension (seat plate 43) of the opening / closing body 15 to the guide rail 16 in a state where the leading end of the extension (43) is in contact with the contact portion (lower frame 33) that contacts the leading end of the extension (43). It is a structure of an opening / closing body device having The drive unit 17 is characterized by operating to apply a driving force in the opening direction to the opening / closing body 15 in a state where the opening / closing body 15 closes the opening 11 and the locking unit 19 is locked.

[0007] In the structure of this opening / closing body device, the opening / closing body 15 of the opening / closing body device 13 is provided on the outdoor side of the glass window 41 at the opening 11 of the building. The opening / closing body 15 can close the opening 11 by the operation of the drive unit 17. The drive unit 17 may be either electric or manual. The opening / closing body 15 that has closed the opening 11 covers the glass window 41 attached to the sash frame 37 of the opening 11. The opening / closing body 15 closes the opening 11, and is locked by the locking unit 19 locking the leading end (seat plate) 43 that is extended to the guide rail 16. In this locked state, the movement of the opening / closing body 15 in the opening direction is restricted by the locking unit 19, and the movement in the closing direction is restricted by the contact portion (lower frame) 33. In the structure of the opening / closing body device, in this locked state, the drive unit 17 operates to apply a driving force in the opening direction to the opening / closing body 15. When the drive unit 17 drives the opening / closing body 15 in the opening direction in a state where the leading end 43 that is extended is locked by the locking unit 19, a tension (T) due to a pulling force is generated between the winding base end (winding unit 35) and the leading end 43 that is extended of the opening / closing body 15. Since the opening / closing body 15 covers the glass window 41 in a planar shape, when the tension T is applied and stretched between the winding unit 35 and the leading end 43 that is extended, the slack in the direction approaching the glass window 41 is suppressed compared to the state where the tension T is not applied. That is, the flexibility to bend toward the glass window 41 is reduced, and the bending is decreased. In the opening / closing body device before the application of the present invention, when a flying object approaches, for a relatively light flying object or a flying object with a low speed, the opening / closing body 15 may be deformed to some extent, but the deformed opening / closing body 15 will not reach the glass window 41. Therefore, the impact will not be transmitted to the glass window 41, and the glass window 41 will not break. On the other hand, when the mass and speed of the flying object are above a certain level, deformation (bending) of the opening / closing body 15 may occur such that it reaches the glass window 41 from somewhere on the opening / closing body 15. In this case, the impact may be transmitted to the glass window 41, and the glass window 41 may break. In contrast, in the structure of the opening / closing body device of the present invention, when a flying object hits the opening / closing body 15 with a tension T applied thereto. As a result, due to the presence of the tension T, the deformation of the opening / closing body 15 in the direction approaching the glass window 41 is smaller than before, and the opening / closing body 15 is less likely to bend. That is, the bending is reduced, the impact is less likely to be transmitted, and the glass window 41 is less likely to break. Thereby, the limit value of the impact force that can protect the glass window 41 when the flying object collides with the opening / closing body 15 can be improved.

[0008] The structure of the opening / closing body device according to claim 2 of the present invention is the structure of the opening / closing body device according to claim 1, characterized in that the opening / closing body 15 is a shutter curtain 15 formed by connecting strip-shaped slats 45 with their long sides connected to each other.

[0009] In the structure of this opening and closing body device, the opening and closing body 15 is a shutter curtain 15 formed by connecting strip-shaped slats 45 along their long sides. The shutter curtain 15 has parallel slats 45 arranged in the opening and closing direction, and there is a slight clearance at each connecting portion between the slats 45. Therefore, in the shutter curtain 15 where a large number of slats 45 are connected, the clearances in the opening and closing direction accumulate, and even in the closed state, some parts are likely to bend. Also, since there is a clearance at the connecting portion of the shutter curtain 15, each individual slat 45 itself can be freely deformed. Furthermore, as described above, even when in the closed state, the shutter curtain 15 may be further extended slightly. The shutter curtain 15 may be bent by wind or the like due to these combined effects. In the structure of the opening and closing body device, a tension T is applied to the shutter curtain 15. As a result, the clearance generated at the connecting portion between the slats 45 is less likely to loosen. That is, in the shutter curtain 15 in the closed state, the connecting portions between the slats 45 are pulled in the opening direction and come into contact. Therefore, even in the shutter curtain 15 where a large number of slats 45 are connected, the clearances in the opening and closing direction do not accumulate, and it becomes difficult to bend in the closed state. Also, since the clearance at the connecting portion does not act in the loosening direction, the free deformation of each individual slat 45 itself is restricted. Furthermore, since the tension T is applied to the shutter curtain 15 from the drive unit 17, it will not be further extended in the closed state. The shutter curtain 15 has these combined effects in the direction of suppressing bending, so the limit value of the impact force that can protect the glass window 41 when a flying object collides with the shutter curtain 15 can be improved.

[0010] The structure of the opening and closing body device according to claim 3 of the present invention is the structure of the opening and closing body device according to claim 1 or 2, characterized in that the drive unit 17 uses an electric motor 23 as a drive source to open and close the opening and closing body 15.

[0011] In the structure of this opening / closing body device, with the lock part 19 locked, when the electric motor 23 of the drive part 17 is driven in the opening direction, tension is applied to the opening / closing body 15. In the structure of the opening / closing body device, even when the lock part 19 is not released, the electric motor 23 can be operated to perform an operation to open the opening / closing body 15. In the case of electric operation, normally, after unlocking, the electric motor 23 is driven to operate in the direction of opening the opening / closing body 15. However, in the structure of this opening / closing body device, even in the locked state, that is, without unlocking, the electric motor 23 rotates to apply the tension T. Note that, as an example, the operation to open the opening / closing body 15 and the operation to apply tension can be caused by continuously driving the electric motor 23.

That is, the timing to apply the tension T is mainly controlled based on a trigger signal from the outside. The drive part 17, which is a drive source for opening and closing the opening / closing body 15, may be either a spring that accumulates and assists the rotational force during manual opening and closing or an electric motor 23. Here, an external trigger signal can be, for example, as a user's judgment, a manually operated ON / OFF switch. The ON / OFF switch is provided separately from the opening / closing switch of the opening / closing body 15 and is turned ON when it is considered dangerous due to a typhoon. It can be assumed that a tension T is applied from this operation. The ON / OFF switch can be referred to as, for example, a typhoon-resistant switch or a typhoon-countermeasure switch.

[0015] In this structure of the opening / closing body device, in order for the drive unit 17 to enable start / stop control, it is necessary to detect the locking of the lock unit 19 and receive an external trigger signal. That is, the drive unit 17 is not activated if the lock unit 19 is not locked. Also, the drive unit 17 is not activated if it does not receive a trigger signal. That is, the timing for applying the tension T cannot be based on control based on an external trigger signal unless after the lock unit 19 has operated (locked).

In the opening 11, a net 47 is disposed outside the opening / closing body 15 so as to be freely wound up and paid out at a distance from the opening / closing body 15. The net 47 covers the opening / closing body 15 in a state where the opening / closing body 15 closes the opening 11, and is characterized in that a force in the opening direction is applied.

[0037] In the structure of this opening / closing body device, the opening / closing body 15 that closes the opening 11 is covered by the net 47 from the outside. The net 47 is disposed at a distance from the opening / closing body 15. The leading end of the pay-out of this net 47 is locked to, for example, the lower frame 33 of the sash frame 37 or an arm 51 provided on the lower frame. A force in the opening direction is applied to the net 47. That is, the net 47 is stretched in a state where tension is generated between the net winding portion 53 and the leading end of the pay-out. In the structure of this opening / closing body device, when a flying object flies in, before the flying object hits the opening / closing body 15, it hits the net 47, and the impact is cushioned by the net 47. The speed of the flying object is slowed down by the net 47 and made to hit the opening / closing body 15. That is, before the flying object directly hits the opening / closing body 15, the net receives the flying object. Thereby, at least a part of the kinetic energy of the flying object is absorbed by the net 47, and when the flying object hits the opening / closing body 15, the impact force by the amount absorbed by the net 47 is reduced.

[0038] The structure of the opening / closing body device according to claim 17 of the present invention is provided on the outdoor side of a glass window 41 of an opening 11 of a building, and includes an opening / closing body 15 that opens and closes the opening 11, and a pair of parallel guide rails 16 that are arranged sandwiching the opening 11 and guide both sides orthogonal to the opening / closing direction of the opening / closing body 15, and a drive unit 17 that opens and closes the opening / closing body 15. That is, In the opening 11, a net 47 is disposed between the opening / closing body 15 and the glass window 41 so as to be freely wound and unwound while being separated from the opening / closing body 15 and the glass window 41. The net 47 is characterized in that an opening-direction force is applied between the opening / closing body 15 and the glass window 41 when the opening / closing body 15 closes the opening 11.

[0039] In this structure of the opening / closing body device, the net 47 is disposed between the opening / closing body 15 and the glass window 41. The net 47 is disposed separated from the opening / closing body 15 and the glass window 41. Even in this case, an opening-direction force is applied to the net 47. That is, the net 47 is stretched with a tension T generated between the net winding unit 53 and the leading end of the unwound portion. If the net 47 is configured to be disposed inside the opening / closing body 15, it is more preferable that the net 47 is made of a soft material. In this structure of the opening / closing body device, when the metal opening / closing body 15 is deformed, the net 47 slightly cushions the opening / closing body 15 from directly hitting the glass window 41, preventing it from directly hitting the glass window 41. That is, the same effect as providing a buffer between the opening / closing body 15 and the glass window 41 can be obtained. In addition to this, in this structure of the opening / closing body device, since the net 47 is disposed inside the opening / closing body 15, the net 47 is not exposed to rain and wind, deterioration of the net 47 can be suppressed, and when the net 47 is in use, the extended net 47 does not appear on the exterior.

Also, on the premise of locking by the locking part, malfunction in which the opening / closing body is driven by the electric motor 23 and opened by the operation of the ON / OFF switch can be prevented, and tension can be surely applied.

[0051] According to the structure of the opening / closing body device described in claim 12 of the present invention, by using a signal from weather information as a trigger signal from the outside, the glass can be automatically made less likely to break even during bedtime, for example.

[0052] According to the structure of the opening / closing body device described in claim 13 of the present invention, by using a signal from weather information as a trigger signal from the outside, even when, for example, going to bed, if the opening / closing body is in a locked state at the locking part, the glass can be automatically made less likely to break.

[0054] According to the structure of the opening / closing body device described in claim 15 of the present invention, by using a signal from weather information as a trigger signal from the outside, even when, for example, going to bed, if the opening / closing body is in a locked state at the locking part, the electric motor is driven and tension is applied, and the glass can be automatically made less likely to break.

[0055] According to the structure of the opening / closing body device described in claim 16 of the present invention, since the opening / closing body is covered with a net with tension applied, when a flying object collides with the window shutter, the impact can be mitigated, and the glass of the sash frame inside the shutter can be made less likely to break.

Mode for Carrying Out the Invention

[0058] Hereinafter, embodiments according to the present invention will be described with reference to the drawings. FIG. 1 is a side sectional view of an opening 11 provided with the structure of the opening / closing body device according to the first embodiment. Deposit The structure of the opening / closing body device according to the first embodiment is that the opening / closing body device is a shutter device 13. Further, the opening / closing body is a shutter curtain 15. The shutter device 13 has a shutter curtain 15, a guide rail 16, a drive unit 17, and a lock unit 19.

[0059] The structure of the opening / closing body device is suitably used for a winding type shutter device 13 that opens and closes the opening 11 of the building by raising and lowering the shutter curtain 15. The opening 11 is formed, for example, on the outer wall 21 of the building. The shutter device 13 may be either a manually operated winding type shutter device 13 or an automatic winding type shutter device 13 provided with an electric drive unit 17.

[0060] In the present embodiment, the drive unit 17 is configured to include a drive mechanism unit, an electric motor 23, and a control unit 25. The drive mechanism unit has a sprocket 27 and a chain 29. The drive unit 17 is also referred to as an opening / closing machine. The drive unit 17 opens and closes the shutter curtain 15 using the electric motor 23 as a drive source.

[0061] In this embodiment, an example in which the shutter curtain 15 moves up and down in the vertical direction will be described. However, the shutter device 13 may be a so-called horizontal draw shutter device in which the shutter curtain 15 moves in the horizontal direction, which is the lateral direction, to open and close the facing opening of a small store.

[0062] The shutter device 13 has a horizontally long rectangular parallelepiped-shaped storage portion 31 fixed to the upper part of the opening 11. On the left and right sides of the opening 11, a pair of parallel guide rails 16 extending in the vertical direction are fixed. The guide rails 16 are arranged with the opening 11 therebetween and guide the curtain edge portions on both sides orthogonal to the opening and closing direction of the shutter curtain 15.

[0063] At the lower end of the opening 11, a lower frame 33 extending in the frontage direction is fixed. The lower ends of the pair of guide rails 16 are respectively connected to one end and the other end of the lower frame 33. On the lower surface of the storage portion 31, a slit-shaped curtain entrance / exit (not shown) extending along the opening frontage direction of the opening 11 is provided. From the curtain entrance / exit, the shutter curtain 15 wound around and stored in the winding portion 35 is fed out from the leading end side.

[0064] Thereby, the shutter device 13 is provided on the outdoor side of the sash frame 37 of the opening 11 of the building, and the shutter curtain 15 can open and close the opening 11. A plurality of glass windows 41 with glass 39 fitted therein are attached to the sash frame 37 as sliding shoji. The shutter curtain 15 will be provided outside this glass window 41.

[0065] The guide rails 16 guide by restricting the passing of both edge portions along the opening and closing direction of the shutter curtain 15 through slits (not shown). The passing restriction is performed by attaching a passing prevention member (not shown) made of a resin material having a T-shaped cross section to both edge portions of the shutter curtain 15 and engaging this passing prevention member with the slits.

[0066] The shutter curtain 15 drawn out from the curtain entrance and exit is guided by being inserted into the guide rails 16 on both sides in the direction of the opening width. The tip of the shutter curtain 15 in the drawing-out direction is a seat plate 43 formed to be long across the opening width direction. The shutter device 13 draws out the shutter curtain 15 from the curtain entrance and exit of the storage section 31, guides it along the guide rails 16, descends the opening 11, and closes the opening 11 when the seat plate 43 lands on the contact portion of the lower frame 33. Further, when the shutter curtain 15 is wound into the storage section, the shutter device 13 guides it along the guide rails 16, raises the shutter curtain 15 to the opening 11, and opens the opening 11 when the seat plate 43 hits the curtain entrance and exit.

[0067] In the present embodiment, the shutter curtain 15 is formed by connecting a plurality of strip-shaped slats 45 formed to be long in the opening width direction with their long sides connected to each other. By engaging the upper and lower edges where the slats have their long sides with each other, the shutter curtain 15 is deployed in a planar shape along the vertical plane and can be wound up in a cylindrical shape around the horizontal axis. The upper edge of the shutter curtain 15 is fixed to a cylindrical winding section 35 that rotates around a stationary shaft (not shown) provided in the storage section, and is wound around the outer periphery of the winding section 35.

[0068] The winding section 35 is driven to rotate forward and backward by the drive section 17. That is, the drive section 17 opens and closes the shutter curtain 15. The winding section 35 is provided with a sprocket 27 at one end and is connected to an opening and closing machine (such as an electric motor 23) via a chain 29. The drive of the electric motor 23 is controlled by the control section 25. The control section 25 can have a CPU (Central Processing Unit). The sprocket 27, the chain 29, the electric motor 23, and the control section 25 constitute the drive section 17.

[0069] Alternatively, it may be configured to drive the winding section 35 in combination with a worm gear. Also, a configuration using a tubular motor in which the electric motor 23 as the drive source is incorporated into the winding section may be used.

[0070] A coiled spring (not shown) is externally inserted onto the shaft. The spring has a length, for example, from approximately the center in the longitudinal direction of the shaft to one end. One end of the spring is fixed to the winding portion 35. The other end of the spring is fixed to the shaft. When the winding portion 35 is rotated together with the shutter curtain 15, the spring is twisted about the shaft as the center of rotation, deforms in the diameter-reducing direction or the diameter-increasing direction against the spring elastic force, and the repulsive force is accumulated. This accumulated repulsive force contributes to reducing the descending speed when the shutter curtain 15 descends and reducing the winding torque when the shutter curtain 15 is wound up.

[0071] The lower end of the shutter curtain 15 is a long seat plate 43. The shutter curtain 15 and the seat plate 43 are made of, for example, an extruded material made of aluminum. A lock portion 19 having a locking device (not shown) is provided on the seat plate 43. The lock portion 19 locks the seat plate 43 to the guide rail 16 in a state where the seat plate 43, which is the leading end of the payout of the shutter curtain 15, and the lower frame 33 as the contact portion that contacts this seat plate 43 are in contact with each other.

[0072] The locking device is attached to approximately the central portion in the longitudinal direction of the seat plate 43. The locking device has a retractable locking bar (not shown) that protrudes from both ends in the longitudinal direction of the seat plate 43 toward the guide rail 16. The locking bar engages with a protrusion (not shown) provided in the guide rail 16 to restrict the movement (ascending) of the shutter curtain 15 in the opening direction. That is, the shutter curtain 15 is locked.

[0073] Figure 2 is an operation diagram of the shutter device 13. The drive unit 17 operates to apply a driving force (rotational force a) in the opening direction to the shutter curtain 15 in a state where the shutter curtain 15 closes the opening 11 and the lock portion 19 is locked. As a result, a tensile force (tension T) is applied to the shutter device 13.

[0074] The drive unit 17 is controlled to start and stop by a trigger signal (external signal) input from the outside to the control unit 25. The start / stop control activates the drive in the opening direction to the electric motor 23 when the control unit 25 detects the locking of the locking unit 19 and the control unit 25 receives an external signal. Preferably, after detecting the locking of the locking unit 19, the drive of the electric motor 23 is performed based on the reception of the external signal. The shutter curtain 15 is pulled by the winding unit 35 when a driving force in the opening direction is applied in a state where the locking unit 19 is locked, and a tension (tension T) is applied between the winding unit 35 and the locking unit 19.

[0075] The control unit 25 includes an external port (not shown) configured to electrically couple an external signal. When a cable is coupled to the external port, the external signal is received and supplied to the CPU of the control unit 25. The external port can include, for example, a Universal Serial Bus (USB) port, a mini-USB port, a serial port, etc. Further, the control unit 25 may receive an external signal from an electronic device such as a laptop computer, a desktop computer, a tablet computer, a smartphone, a dedicated device, etc. through the external port.

[0076] Here, an example of the timing for applying the tension T will be described.

[0077] [Example 1] When the shutter is fully closed, the tension T is always applied.

[0078] [Example 2] Normally, the tension T is not applied, and a tension ON / OFF switch is provided so that the user can judge based on weather conditions, etc. and switch the tension ON / OFF switch when necessary.

[0079] [Example 3] Install various sensors that can detect wind power outdoors, etc., and apply tension T when strong winds occur. For example, when strong winds are detected, continuously apply tension T for a certain period of time (1 hour / 3 hours / 6 hours, etc.) to prepare for the next strong wind. Or, when strong winds are detected instantaneously, apply tension T instantaneously to deal with flying objects flying due to the strong winds themselves. For example, apply tension T in about 0.5 msec and release it in a few seconds, etc., which may also be a method.

[0080] [Example 4] Link with the weather warning linkage mechanism of a dedicated communication system (such as the CeleConnect (registered trademark) system, etc.), and apply tension T when receiving weather warnings such as typhoons, and release tension T when the warning is lifted.

[0081] [Example 5] Install impact sensors on the shutter curtain 15, for example, on the outer surface of the slats, etc., and instantaneously apply tension T at the moment when a flying object actually hits. The control unit 25 can adopt any one or any combination of the above external signals as a trigger signal.

[0082] The type of the shutter device 13 to which the structure of the opening and closing body device is applied can be either an electric type (an automatic winding type shutter device 13) or a manual type (a manual winding type shutter device 13). For example, in the electric type, as described above, use the electric motor 23 for shutter opening and closing to pull up the shutter curtain 15 and apply tension T. Also, in the manual type, set the force of the above-described spring used for assisting the opening and closing operation to be stronger than that of a normal shutter device 13. In this case, when closing the shutter curtain, it is necessary to close it with a stronger force than a normal shutter curtain 15.

[0083] Next, the operation of the configuration in the above-described first embodiment will be described.

[0084] In the structure of the opening / closing body device according to this embodiment, the shutter device 13 is provided on the outdoor side of the glass window 41 at the opening 11 of the building. The shutter curtain 15 can close the opening 11 by the operation of the drive unit 17. The drive unit 17 may be either electric or manual. The shutter curtain 15 that closes the opening 11 covers the glass window 41 attached to the sash frame 37 of the opening 11.

[0085] The shutter curtain 15 closes the opening 11 and is locked by locking the leading end of the extension by the locking portion 19 to the guide rail 16. In this locked state, the movement of the shutter curtain 15 in the opening direction is restricted by the locking portion 19, and the movement in the closing direction is restricted by the contact portion (lower frame 33). In the structure of the opening / closing body device, in this locked state, the drive unit 17 operates to apply a driving force in the opening direction to the shutter curtain 15.

[0086] As shown in FIG. 2, when the drive unit 17 drives in the opening direction with the shutter curtain 15 in a state where the leading end of the extension is locked by the locking portion 19, a tension (tension T) due to the pulling force is generated between the winding base end, the winding portion 35, and the leading end of the extension, the seat plate 43.

[0087] Since the shutter curtain 15 covers the glass window 41 in a planar manner, when the tension T is applied and stretched between the winding portion 35 and the seat plate 43, the slack in the direction approaching the glass window 41 is suppressed compared to the state where the tension T is not applied. That is, the flexibility to bend toward the glass window 41 is reduced, and the bending is decreased.

[0088] FIG. 3 is an operation diagram of a shutter device to which the present invention is not applied. In a shutter device to which the present invention is not applied, when a flying object approaches, for a relatively light flying object or a flying object with a low speed, the shutter curtain 15 is deformed to some extent, but the deformed shutter curtain 15 does not reach the glass window 41. Therefore, the impact is not transmitted to the glass window 41, and the glass 39 does not break. On the other hand, when the mass and speed of the flying object exceed a certain level, deformation or bending of the shutter curtain 15 occurs such that the shutter curtain 15 reaches the glass window 41 from somewhere. In this case, the impact is transmitted to the glass window 41, and as shown in FIG. 3, the glass 39 may break.

[0089] Note that even when the shutter curtain 15 of the shutter device 13 is in the closed state, the shutter curtain 15 may be further drawn out slightly. In the winding unit 35, since there is an excess portion in the shutter curtain 15 and the winding unit 35 itself has not completely stopped rotating, rotation in the drawing-out direction may occur. In this case, the shutter curtain 15 that is closed at the opening 11 is more likely to bend. That is, the impact is more likely to be transmitted to the glass window 41, and the glass 39 is more likely to break.

[0090] On the other hand, in the structure of the opening / closing body device, as shown in FIG. 2, when a flying object hits the shutter curtain 15 with a tension T applied thereto. As a result, due to the tension T, the deformation of the shutter curtain 15 in the direction approaching the glass window 41 is smaller than before, and the shutter curtain 15 is less likely to bend. Further, the shutter curtain 15 is in a state of being stretched between the winding unit (winding base end) 35 and the leading end of the drawn-out portion (seat plate) 43. That is, the bending is reduced, the impact is less likely to be transmitted, and the glass 39 is less likely to break. Thereby, the limit value of the impact force capable of protecting the glass window 41 when a flying object collides with the shutter curtain 15 can be improved.

[0091] In the structure of this opening / closing body device, the shutter curtain 15 is a shutter curtain 15 formed by connecting strip-shaped slats 45 along their long sides. The shutter curtain 15 has parallel slats 45 connected in the opening / closing direction, and there is a slight clearance at the connecting portions between the slats. For this reason, in the shutter curtain 15 where a large number of slats 45 are connected, the clearances in the opening / closing direction accumulate, and even in the closed state, it is easy for some parts to bend. Also, since there is a clearance at the connecting portion of the shutter curtain 15, each individual slat itself can be freely deformed. Furthermore, as described above, the shutter curtain 15 may be further extended slightly even when in the closed state. The shutter curtain 15 will be bent by wind or the like due to the combined action of these factors.

[0092] In the structure of the opening / closing body device, a tension T is applied to the shutter curtain 15. As a result, the clearance generated at the connecting portions between the slats is less likely to loosen. That is, in the shutter curtain 15 in the closed state, the connecting portions between the slats are pulled in the opening direction and are in a contacting state. For this reason, even in the shutter curtain 15 where a large number of slats 45 are connected, the clearances in the opening / closing direction do not accumulate, and it becomes difficult to bend in the closed state. Also, since the clearance at the connecting portion does not act in the loosening direction, the free deformation of each individual slat itself is restricted. Furthermore, since the tension T is applied to the shutter curtain 15 from the drive unit 17, it will not be further extended in the closed state.

[0093] Since the combined action of these factors on the shutter curtain 15 is in the direction of suppressing bending, the limit value of the impact force that can protect the glass window 41 when a flying object collides with the shutter curtain 15 can be improved. As a result, the clearance (play at the connecting portion) generated between the slats disappears due to the tension T applied to the shutter curtain 15, and the bending of the shutter curtain 15 in the direction of the glass window during a flying object collision is suppressed.

[0094] In addition, in the structure of this opening / closing body device, with the lock portion 19 locked, when the electric motor 23 of the drive portion 17 is driven in the opening direction, tension T is applied to the shutter curtain 15.

[0095] In the case of a normal shutter device, generally, the electric motor 23 does not rotate unless the lock portion 19 is released.

[0096] In the structure of the opening / closing body device, even when the lock portion 19 is not released, the electric motor 23 can be operated to perform an operation to open the shutter curtain 15. In the case of electric operation, normally, after unlocking, the electric motor 23 is driven to operate in the direction of opening the shutter curtain 15. However, in the structure of this opening / closing body device, even without unlocking, the electric motor 23 rotates to apply tension T.

[0097] Note that the operation to open the shutter curtain 15 (the operation to apply tension T) can be caused, for example, by continuously driving the electric motor 23. As a result, by driving the electric motor 23 in the opening direction of the shutter curtain 15, tension T can be easily applied to the shutter curtain 15, and the applied tension T can be easily released.

[0098] In the structure of this opening / closing body device, in order for the drive portion 17 to enable start / stop control, it is necessary to detect the locking of the lock portion 19 and receive a trigger signal from the outside. That is, the drive portion 17 is not activated unless the lock portion 19 is locked. Also, the drive portion 17 is not activated unless it receives a trigger signal. That is, the timing for applying tension T is mainly controlled based on a trigger signal from the outside.

[0099] Note that the drive source for opening and closing the shutter curtain 15 of the drive portion 17 may be either a spring that accumulates and assists the rotational force during manual opening and closing or the electric motor 23.

[0100] Here, an external trigger signal can be, for example, as a judgment of the user, a manually operated ON / OFF switch. The ON / OFF switch is provided separately from the opening / closing switch of the shutter curtain 15 and is turned ON when it is considered dangerous due to a typhoon. It can be assumed that a tension T is applied from the operation. The ON / OFF switch can be referred to as, for example, a typhoon-resistant switch or a typhoon-countermeasure switch.

[0101] In addition, external trigger signals include, for example, detection signals from an anemometer, a wind force meter, and signals from meteorological information. As a result, by using a manually operated ON / OFF switch, wind force sensing information, meteorological information, etc. as trigger signals, it is possible to automatically make the glass 39 less likely to break even, for example, during bedtime.

[0102] In the structure of this opening / closing body device, the drive source for opening and closing the shutter curtain 15 is the electric motor 23. Here, as external trigger signals, as a judgment of the user, there are a manually operated ON / OFF switch, detection signals from an anemometer, a wind force meter, and signals from meteorological information. As a result, by using a manually operated ON / OFF switch, wind force sensing information, meteorological information, etc. as trigger signals, it is possible to automatically operate the electric motor 23 of the drive unit 17 even, for example, during bedtime, and make the glass 39 less likely to break.

[0103] Next, the second embodiment will be described.

[0104] FIG. 4 is a side sectional view of the opening 11 provided with the structure of the opening / closing body device according to the second embodiment. In the second embodiment, members equivalent to those shown in FIGS. 1 to 3 are denoted by the same reference numerals, and redundant explanations are omitted. In the structure of the opening / closing body device according to the second embodiment, a net 47 is provided outside the shutter curtain 15. The net 47 is arranged so as to be spaced apart from the shutter curtain 15 and can be wound up and unwound freely.

[0105] The net 47 has a locking portion 49 at the leading end of the payout. The locking portion 49 can be locked and unlocked to an arm 51 fixed to the sash frame 37.

[0106] The net 47 is provided with a net winding portion 53, for example, on the lower surface of the storage portion 31. The net 47 is manually pulled out from the net winding portion 53. A release spring (not shown) is provided in the net winding portion 53. When the net winding portion 53 is rotated, the release spring is twisted about the rotation center, and a repulsive force is accumulated. This accumulated repulsive force applies a tension T to the pulled-out net 47 and becomes an automatic winding-up torque for the net 47. The structure of the opening / closing body device according to the second embodiment is such that the net 47 is provided in a shutter device 55 in which no tension T is applied to the closed shutter curtain 15.

[0107] The net 47 covers the shutter curtain 15 in a state where the shutter curtain 15 closes the opening 11, and a force in the opening direction (tension T) is applied. The net 47 has the image of a roller screen attached to the outside of the glass window 41.

[0108] FIG. 5 is a side sectional view of the opening 11 having the structure of the opening / closing body device according to Modification 1 of the second embodiment in which the net 47 is inclined and attached. The net 47 may be attached to be inclined with respect to the shutter curtain 15. In this case, by shortening the arm 51 to which the locking portion 49 is locked and unlocked, the locking portion 49 below the net winding portion 53 at the upper front can be positioned deeper, and the net 47 can be stretched obliquely. By being inclined, the net 47 can release the impact received from flying objects more than receiving it in the vertical direction.

[0109] FIG. 6 is a side sectional view of the opening 11 having the structure of the opening / closing body device according to Modification 2 of the second embodiment in which the net 47 is attached between the shutter curtain 15 and the glass window 41. The structure of the opening / closing body device may be such that the net 47 is arranged between the shutter curtain 15 and the glass window 41 and spaced apart from the shutter curtain 15 and the glass window 41. In this case, the net winding unit 53 is arranged between the shutter curtain 15 and the glass window 41. Also, the locking portion 49 is locked to the lower frame 33 or the like between the shutter curtain 15 and the sash frame 37.

[0110] Next, the operation of the configuration in the above-described second embodiment will be described.

[0111] In the structure of this opening / closing body device, the shutter curtain 15 that closes the opening 11 is covered by the net 47 from the outside. The net 47 is arranged spaced apart from the shutter curtain 15. The leading end of the extended net 47 is locked to, for example, the lower frame 33 of the sash frame 37 or the arm 51 provided on the lower frame 33. A force in the opening direction is applied to the net 47. That is, the net 47 is stretched in a state where a tension T is generated between the net winding unit 53 and the leading end of the extended net.

[0112] In the structure of this opening / closing body device, when a flying object flies in, before the flying object hits the shutter curtain 15, it hits the net 47, and the impact is cushioned by the net 47. The speed of the flying object is reduced by the net 47 and it is made to hit the shutter curtain 15. That is, before the flying object directly hits the shutter curtain 15, the net 47 receives the flying object.

[0113] As a result, at least a part of the kinetic energy of the flying object is absorbed by the net 47, and when the flying object hits the shutter curtain 15, the impact force by the amount absorbed by the net 47 is reduced. As a result, since the shutter curtain 15 is covered by the net 47 with the tension T applied, when a flying object collides with the window shutter, the impact can be mitigated and the glass 39 of the sash frame 37 inside the shutter is less likely to break.

[0114] Also, in the structure of the opening / closing body device according to the second modification, the net 47 is disposed between the shutter curtain 15 and the glass window 41. The net 47 is disposed at a distance from the shutter curtain 15 and the glass window 41. Also in this case, a force in the opening direction is applied to the net 47. That is, the net 47 is stretched with a tension T generated between the net winding portion 53 and the leading end of the payout.

[0115] If the net 47 is configured to be disposed inside the shutter curtain 15, it is more preferably made of a soft material.

[0116] In the structure of this opening / closing body device, when the metal shutter curtain 15 is deformed, the net 47 cushions the shutter curtain 15 from directly hitting the glass window, so that the shutter curtain 15 does not directly hit the glass window 41. That is, the same effect as providing a buffer between the shutter curtain 15 and the glass window 41 can be obtained.

[0117] In addition to this, in the structure of this opening / closing body device, since the net 47 is disposed inside the shutter curtain 15, the net 47 is not exposed to rain and wind, deterioration of the net 47 can be suppressed, and when the net 47 is used, the extended net 47 does not appear on the appearance. As a result, since the net 47 is provided between the shutter curtain 15 and the glass window 41, the net 47 serves as a buffer, the impact applied from the shutter curtain 15 to the glass window 41 can be reduced, and moreover, deterioration of the net 47 can be suppressed and the appearance during use of the net does not deteriorate because the net 47 does not appear on the appearance.

[0118] Therefore, according to the structure of the opening / closing body device according to the first embodiment, since tension T is applied to the shutter curtain 15, when a flying object collides with the window shutter, the glass 39 of the sash frame 37 inside the shutter can be made less likely to break. Also, according to the structure of the opening / closing body device according to the second embodiment, since tension T is applied to the net 47, when a flying object collides with the window shutter, the net 47 serves as a buffer and the glass 39 of the sash frame 37 inside the shutter can be made less likely to break.
