Description

[Technical Field]

[0001] The present invention relates to a buffer device and a glass breakage prevention method for reducing the risk of window glass breakage due to breakage of a shutter device in a glass window having a shutter device installed on the exterior side. [Background technology]

[0002] In recent years, due to the effects of global warming and other factors, there has been a trend toward typhoons becoming larger and stronger, and there have been cases where debris from typhoons and tornadoes has collided with houses. Patent Documents 1 and 2 disclose techniques for protecting windows from wind pressure caused by typhoons and the resulting collision of flying objects. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6924339 [Patent Document 2] Patent No. 7175444 Summary of the Invention [Problem to be solved by the invention]

[0004] The technologies disclosed in Patent Documents 1 and 2 both require the installation of components for attaching window protection components (screens or cover components) to structures (exterior walls) or the ground around the windows, and essentially require construction by a contractor, which means that the construction is time-consuming and costly. Furthermore, the technologies disclosed in Patent Documents 1 and 2 were not originally intended to be applied to windows with shutter devices, but rather were intended to protect windows without shutter devices (the conventional general understanding was that there was no idea of ​​attaching components (screens or cover components) to protect windows in addition to the shutter device, which is a protective device). However, with the increasing scale and strength of typhoons in recent years, there is a concern that even if a shutter device is present, if a flying object hits the window, the shutter curtain (slats) will deform, and this could hit the window glass and cause the window glass to break.

[0005] In view of the above, the present invention aims to provide a buffer device and a glass breakage prevention method at a relatively low cost to reduce the risk of window glass breakage due to breakage of the shutter device in a glass window where the shutter device is installed on the outside. [Means for solving the problem]

[0016] (Configuration 11) This is a glass breakage prevention method for reducing the risk of window glass breakage due to damage to the shutter device, by removably attaching a buffer device to the shutter curtain at a position opposite the glass surface, so that when an impact is applied to the shutter curtain from the outside and the shutter curtain deforms inward, the impact force is absorbed by the buffer device.

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be realized, and are not intended to limit the scope of the present invention.

[0022] <Embodiment 1> Figures 1 and 2 are diagrams showing the installation state of a shock absorber 1 according to a first embodiment of the present invention, with Figure 1 being a longitudinal cross-sectional view and Figure 2 being a transverse cross-sectional view (neither is a strict cross-sectional view, but is shown with some simplifications etc. to allow the positional relationship of each component to be understood). The shock absorber 1 of this embodiment is a shock absorber installed between a glass window 2 and a shutter device 3 provided on the outer side of the glass window 2, a mounting member 12 for detachably mounting the shock absorber 1 to a shutter curtain 31 at a position facing the glass surface of a sash (shoji) 22; and an impact buffering member 11 joined to the mounting member 12, The shutter curtain 31 is configured to absorb the impact force when it is deformed inward due to an external impact, thereby reducing the risk of glass breakage.

[0023] The shock absorbing member 11 has a bag-shaped member filled with a fluid inside, and in this embodiment, is configured by an air bag filled with air inside. 1 and 2, the structure is such that the glass surface of the sash (paper screen) 22 is not brought into contact with the glass surface when the glass screen is attached. In this embodiment, the "fluid" is air as an example, but the present invention is not limited to this, and any filler that can absorb or disperse impact force (for example, gases other than air, liquids, liquid-like materials, powders, viscous materials, gel-like materials, etc.) can be used. The "bag-shaped member" can be a flexible or pliable member such as a resin sheet, and can be formed from any material that can retain the "fluid" inside and has the required strength (it may be a composite material, etc.), and can have any shape, such as a spherical or box-like shape. Regarding the material and shape, it is preferable that the part that may come into contact with the glass surface (contact surface) is flexible and configured to provide surface contact (avoiding a configuration in which a hard part makes point contact) so as to avoid applying localized force to the glass surface. The size of the member can also be arbitrary. It may be formed as a relatively small member and installed in multiple pieces, or it may be formed to have an area that covers roughly the entire window glass, as shown in embodiment 2. The fluid injected into the bag-shaped member may be maintained in a pre-injected state (the fluid cannot be removed), or may be configured to allow the fluid to be injected and removed (the bag-shaped member may be provided with a fluid injection / removal section). For example, as shown in embodiment 2, by allowing the fluid to be injected / removed in the same way as a life jacket or the like, the shock absorber is excellent in storability when not in use, and is therefore preferable.

[0024] In this embodiment, the mounting member 12 is configured using a magnet, which allows it to be detachably mounted on the shutter curtain 31 made of steel. In this embodiment, a magnet is used as an example of an "attachment member," but the present invention is not limited to this. Any attachment member that can be attached and detached to the shutter curtain can be used, such as a fitting attachment member that fits into the uneven structure of the slats that make up the shutter curtain, an adhesive attachment member, or a suction cup.

[0025] The glass window (sliding window) 2 has a window frame 21 installed in an opening O formed in a wall W, and a sash (shoji screen) 22 installed so as to be able to be opened and closed. The shock absorber 1 can be applied to glass windows of any configuration (the glass window itself may have any configuration), so a detailed description of the glass window 2 will be omitted here.

[0026] The shutter device 3 has a shutter curtain 31 configured by a plurality of slats joined together so as to be able to rotate with respect to each other, and a winding mechanism 32 that winds up the shutter curtain 31 (opens and closes it up and down). The shock absorbing member 11 can be applied to a shutter device of any configuration (the shutter device itself may have any configuration), so a detailed description of the shutter device 3 will be omitted here.

[0027] FIG. 3 is a schematic diagram showing an example of a procedure for installing the shock absorber 1. As shown in FIG. First, as shown in Figure 3(a), one sash (shoji) 22 of the glass window (sliding window) 2 is opened and the shutter curtain 31 is closed, and the shock absorber 1 is attached to this shutter curtain 31 so that it will be in a position facing the glass surface when the glass window (sliding window) 2 is closed (if the shutter curtain is capable of injecting and extracting fluid, the shock absorber 11 is inflated by injecting fluid and then attached). Here, an example is shown in which three shock absorbers are attached, but any number of shock absorbers may be attached, such as only one (the effect will be greater if the area in which the shock absorbers are present is as wide as possible). Next, as shown in Figure 3(b), the other sash (shoji) 22 is opened, and shock absorbers 1 are attached to the position facing the glass surface of the shutter curtain 31. The number of shock absorbers to be attached is the same as above (note that it is not necessary to attach the same number of shock absorbers on both sides, and it is acceptable to attach different numbers of shock absorbers on each side). When the sash (shoji) 22 is closed, it can be installed as shown in FIG. 3(c). To remove the shock absorber 1, follow the above steps in reverse.

[0028] As described above, the shock absorber 1 of this embodiment does not require the construction of any attachment members to structures (exterior walls) or the ground around the window, and therefore the shock absorber and glass breakage prevention method can be provided at a relatively low cost. The shock absorber of this embodiment is installed in the space between the shutter curtain and the glass window, and is essentially not blown away by wind or the like. Therefore, a relatively simple attachment member can be used (a strong attachment structure is not required, as long as it can exert enough attachment force to maintain its position). In addition, the shock absorber can be constructed using a relatively simple structure such as an air bag, and therefore the shock absorber can be realized at a low cost. As can be seen from the explanation of Figure 3, the installation and removal procedures are very simple and can be completed indoors, making it highly usable and very useful.

[0029] In this embodiment, the shock absorbing member is configured not to come into contact with the glass surface when the shock absorber is installed, but the present invention is not limited to this. The shock absorbing member may be configured to come into contact with the glass surface when installed. However, when using the installation method described in FIG. 3, from the viewpoint of workability, it is preferable that the shock absorbing member is configured not to come into contact with the glass surface (and further, not to come into contact with the sash vertical frame when the sash is opened or closed). Furthermore, by providing a gap between the shock absorbing member and the glass surface, the shock absorbing member can be prevented from coming into contact with the glass surface in cases where the shutter curtain (slat) is subjected to a relatively small external force, etc., and the load can be prevented from being transmitted to the glass surface.

[0030] In this embodiment, the mounting member is an "mounting member for detachably mounting a shock absorber to a shutter curtain," but the present invention is not limited to this, and it may also be an "mounting member for detachably mounting a shock absorber to a glass surface." For example, the shock absorber may be attached to the glass window side by configuring the attachment member using a suction cup or adhesive material, etc., and making it detachable from the glass surface. In this case, the attachment work is performed by attaching the shock absorber to the glass surface from the outside with the shutter open, and then closing the shutter (it is also possible to attach the shock absorber from the inside, although this is somewhat less easy to do).

[0031] In this embodiment, an example is shown in which a plurality of shock absorbers of the same configuration are attached, but the present invention is not limited to this, and shock absorbers of different configurations may be attached. For example, as can be seen from Figure 2, in the case of a sliding door window, the distance between the window glass and the shutter curtain is different on the left and right sides, but to accommodate this, it is possible to use shock absorbers of different sizes on the left and right sides so that the distance between the impact buffering member and the glass surface is the same on the left and right sides (or so that the impact buffering member comes into contact with the glass surface on both the left and right sides).

[0032] In this embodiment, the impact buffering member is inflated when installed, but the present invention is not limited to this. The impact buffering member may not be inflated when installed, but may be configured to inflate when an impact is applied (functioning as a so-called "airbag"). That is, for example, the device may be equipped with an acceleration sensor, a gas supply unit such as a pyrotechnic inflator that uses a solid gas generating agent or a stored gas inflator in which high-pressure gas is filled in a pressure-resistant container, and a control unit, and when the control unit determines that an acceleration greater than a predetermined value has occurred based on a signal from the acceleration sensor, it may be configured to supply gas from the gas supply unit into a bag-shaped member to inflate the bag-shaped member.

[0033] <Embodiment 2> 4 and 5 are diagrams showing a shock absorber according to a second embodiment of the present invention, with Fig. 4(a) being a top view, Fig. 4(b) being a schematic diagram (schematic cross-sectional view) showing the mounted state, Fig. 5(a) being a perspective view seen from the outdoor side, and Fig. 5(b) being a perspective view seen from the indoor side. Note that the same reference numerals are used for components having the same concept as in the first embodiment, and corresponding reference numerals are used for components having similar or corresponding concepts, thereby omitting or simplifying the explanation here.

[0034] The shock absorber 1-2 of this embodiment is a shock absorber installed between a glass window having a window frame 21 and a sash (shoji) 22 and a shutter device (not shown here) provided on the outer side of the glass window. a mounting member 12-2 that is sandwiched between a window frame 21 and a sash (shoji) 22 to detachably mount the shock absorber to the glass window; an impact buffer member 11-2 joined to a mounting member 12-2; a plurality of plate members 113 as rigid members disposed on the outdoor side of the impact buffer member 11-2, and a plurality of pocket portions 112 for holding the plate members; When an external impact is applied to the shutter curtain, causing it to deform inward, the shutter curtain is designed to absorb the impact force, thereby reducing the risk of glass breakage.

[0035] The shock absorbing member 11-2 has a bag-shaped member filled with a fluid inside, and is configured as an air bag filled with air inside, similar to the first embodiment. The shock absorbing member 11-2, which is an air bag, is formed with a retractable air inlet 111, through which air can be injected or released. The fact that the "fluid" may be something other than air and the configuration of the "bag-shaped member" are similar concepts to those explained in embodiment 1, and therefore will not be explained here (in this embodiment, an example is given of one that covers almost the entire glass surface (covers both sashes), but it is also possible to install multiple ones that are large enough to cover one sash, or that have the same size and shape as embodiment 1).

[0036] A plurality of pockets 112 are formed on the outdoor side of the shock absorbing member 11-2, and a vertically long plate member 113 is housed and held in each pocket 112. Pocket portion 112 has an opening on the upper side and is closed on the lower side, and is configured so that plate member 113 can be inserted and removed from the top. In this embodiment, pocket portion 112 is formed from a resin sheet like the shock absorbing member (and the mounting member), but the present invention is not limited to this, and the pocket portion may be formed from any material that can hold a plate member. The plate member 113, which is a rigid member, is a metal plate. In this embodiment, the plate member 113 is a metal plate, but the present invention is not limited to this, and the plate member 113 may be formed using any material (such as a resin plate or a carbon material) that has strength in accordance with the product specifications (based on the design concept). The shock absorbing member 11-2 is flexible and can release the fluid (air) inside, and the plate members 113 are stored in each of the multiple pockets 112 provided in the shock absorbing member 11-2. This allows the plate members 113 to be folded even though they are rigid members, making them easy to store when not in use.

[0037] In this embodiment, the mounting member 12-2 is formed in a sheet shape, and is formed so as to extend outward in the width direction (direction along the opening and closing direction of the window) from both ends of the impact buffer member 11-2. As shown in FIG. 4(b), the shock absorber is sandwiched between a window frame 21 and a sash (shoji screen) 22, thereby allowing the shock absorber to be detachably attached to the glass window. The mounting member 12-2 in this embodiment is formed from a resin sheet, similar to the shock-absorbing member, but the present invention is not limited to this, and the mounting member may be formed using any material that can be sandwiched between the window frame and the sash (so that the sash can be closed with the member sandwiched between them) and has the strength to hold the shock absorber in that state. Also, while the mounting member 12-2 in this embodiment is exemplified as being sheet-shaped, the present invention is not limited to this, and the mounting member may be any shape, such as a string-like material, that can be sandwiched between the window frame and the sash (so that the sash can be closed with the member sandwiched between them). Furthermore, a slip-out prevention part may be formed on the mounting member at a portion closer to the tip of the portion sandwiched between the window frame and the sash (shoji screen) (the portion located on the interior side of the room when mounted), so that the mounting member cannot pass through between the window frame and the sash (shoji screen). This prevents the mounting member sandwiched between the window frame and the sash (shoji screen) from slipping out when the shock absorber 1-2 is mounted. In addition, the position of the slip-out prevention part (the position of the slip-out prevention part relative to the mounting member) may be adjustable.

[0038] As described above, according to the shock absorber 1-2 of this embodiment, as in embodiment 1, there is no need to install any mounting members on structures (exterior walls) or the ground around the window, so the shock absorber and glass breakage prevention method can be provided at a relatively low cost. Furthermore, since multiple plate members 113 as rigid members are provided on almost the entire exterior side of the impact buffering member, when the shutter slats are deformed inward, for example by a flying object, they come into contact with the impact buffering member 11-2, which is an air bag, and tear it, reducing or eliminating the buffering capacity of the impact buffering member 11-2 (the plate members 113 function to protect the impact buffering member 11-2).

[0039] In this embodiment, the pocket portion 112 is formed vertically, but the present invention is not limited to this, and the pocket portion may be formed horizontally (to receive a plate-shaped member horizontally), for example. Furthermore, the pocket portion may be divided into smaller portions to hold the hard members (for example, pockets may be formed in a checkerboard pattern, each of which may hold a hard member). The rigid member may be detachable from the pocket, or may be housed inside the pocket in an undetachable manner. In addition, the hard member may be attached (for example, glued) to the shock absorbing member without using the pocket portion (there may be no pocket portion). Furthermore, the rigid member is not limited to being formed from a plurality of members, but may be formed as a single plate, for example (however, in this case, convenience during storage is reduced).

[0040] <Embodiment 3> Next, as a third embodiment, a gas supply device for inflating the shock-absorbing member described in the first and second embodiments will be described. FIG. 6 is a block diagram showing the configuration of the gas supply device portion of the shock absorber of this embodiment, and FIG. 7 is a flowchart showing an outline of the processing operation thereof. The gas supply device of this embodiment injects / discharges air into / from the shock absorbing member 11-3 (a bag-shaped member having the same concept as the shock absorbing member 11 of the first embodiment and the shock absorbing member 11-2 of the second embodiment). A control unit 131 that controls each unit; an electric air pump 132 serving as a gas supply unit; an air valve 133 provided in the shock absorbing member 11-3, which is a bag-shaped member; a receiving unit 134 which is an interface unit; a remote control device 135; The control unit 131 is configured to supply gas from the electric air pump (gas supply unit) 132 into the shock absorbing member (bag-shaped member) 12-3 to inflate the bag-shaped member when the receiving unit 134, which is an interface unit, receives an instruction signal from the remote control device 135.

[0041] The electric air pump 132, which is the gas supply unit, has a check valve and is connected to the shock absorbing member 11-3, which is a bag-shaped member. The electric air pump 132 is configured to send external air into the bag-shaped member when the internal motor rotates, but not to allow the air inside the bag-shaped member to flow out when the internal motor stops. Air valve 133 is provided in the bag-shaped member and opens and closes based on a signal from the control unit. Note that air valve 133 may be provided at the connection between electric air pump 132 and the bag-shaped member (air valve 133 may also function as the check valve described above). The receiving unit 134 receives a signal from the remote control device 135 (which may be any wireless system, such as an infrared system), and the remote control device 135 is used to externally instruct the injection / exhaust of air into / from the shock absorbing member 11-3.

[0042] The control unit 131 performs the processing shown in FIG. In step 701, it is determined whether or not an instruction to inject air has been issued from remote control device 135 (whether or not an instruction signal has been received by receiver 134). If an instruction to inject air is received, the electric air pump 132 is driven to inject air (step 701: Yes → step 702). Note that air injection is performed by driving the electric air pump 132 for a predetermined time (and then stopping it), or by providing an air pressure sensor and driving the electric air pump 132 until a predetermined air pressure is reached (and then stopping it). Alternatively, the remote control device may be provided with a stop button, and the electric air pump 132 may be driven until a stop instruction is received from the remote control device. This process is performed, for example, in the procedure of Figures 3(a) and (b) described in embodiment 1, when the shock-absorbing member is not inflated and the window is closed as shown in Figure 3(c), and then the user uses the remote control to instruct air to be injected; or when the mounting member 12-2 of the shock-absorbing device 1-2 of embodiment 2 is sandwiched between the window frame and the sash (shoji screen) to install the shock-absorbing device 1-2 (after closing the sash), and then the user uses the remote control to instruct air to be injected.

[0043] When the shock absorber is no longer needed and is to be removed, the user uses the remote control to instruct the air to be released. The control unit 131 monitors whether or not there is an instruction to discharge air from the remote control device 135 (whether or not an instruction signal is received by the receiving unit 134) (step 703), and if there is, it opens the air valve 133 to discharge air (step 703: Yes → step 704).

[0044] As described above, according to the shock absorber having the gas supply device of this embodiment, when installing the shock absorber, the work can be performed with the shock absorber member remaining deflated, and after installation (after the sash (shoji) is closed), the shock absorber member can be inflated at any time, thereby improving the ease of installation.

[0045] In this embodiment, an air pump is used as an example of a gas supply unit, but the present invention is not limited to this, and any gas supply unit that can inflate the impact cushioning member may be used, such as the pyrotechnic inflator or stored gas inflator described above.

[0046] In this embodiment, a command to inflate the shock-absorbing member is given using a remote control device, but the present invention is not limited to this. For example, Bluetooth (registered trademark) may be used as a communication standard so that commands can be given from an existing terminal device such as a smartphone. Furthermore, instead of a receiving unit, a user interface unit such as a switch may be provided as the interface unit, and the shock absorbing member may be inflated based on an input to the user interface unit such as the switch. In this case, after an input is made to a switch or the like provided in the shock absorbing device, the gas supply unit may start operating with a time lag (after waiting for a predetermined time to elapse after the input to the switch or the like) to allow for an operation such as closing a sash (paper screen).

[0047] In each embodiment, a sliding window is used as an example of a "glass window," but the application of the shock absorber device of the present invention is not limited to this, and the shock absorber device of the present invention can be applied to any glass window, such as a fixed window, a sliding window (vertical or horizontal), or a folding window.

[0048] In each embodiment, an air bag filled with a fluid (gas) is used as the shock-absorbing member, but the present invention is not limited to this. The shock-absorbing member can be any material (for example, a foam material such as polystyrene foam, air bubble wrap (so-called "bubble wrap"), gel-like material, a three-dimensional cushioning material made of paper, or a bag-like material filled with a water-absorbing polymer or bead-like foam material) that is flexible and configured to make surface contact (avoiding a configuration in which a hard portion makes point contact) so as to prevent localized force from being applied to the glass surface at the point (contact surface) that may come into contact with the glass surface.
