Description

[Technical Field]

[0001] The present invention relates to a storm shutter. [Background technology]

[0002] Traditionally, houses and the like have been provided with storm shutters that can cover windows. Storm shutters can protect against wind and rain during storms such as typhoons, and can also prevent windows from being damaged by flying objects. Storm shutters include, for example, sliding shutters, which are stored in a door pocket next to the window and can be slid to cover the window as needed, and shutter-type shutters.

[0003] Generally, detached houses are equipped with storm shutters, but some detached houses, condominiums, and apartments do not have storm shutters. However, all of the above-mentioned conventional shutters are expensive, and installing them on all of a home's windows would be quite costly. In addition, in the case of rental properties, renovation work is often prohibited by the contract, making it impossible to install shutters. Summary of the Invention [Problem to be solved by the invention]

[0004] The inventors have noticed that, due to the increasing size of typhoons in recent years and the resulting severe damage, there is an increasing demand among residents of condominiums, apartments, etc. for a system that allows them to easily attach and remove storm shutters to their windows to protect them from debris thrown by typhoons. As mentioned above, it is difficult to carry out construction work, and it is anticipated that there is a strong demand for storm shutters that can be easily attached and removed only in emergencies such as typhoons. The present invention is intended to solve the above-mentioned problems, and has an object to provide a storm shutter that can be easily attached and removed. [Means for solving the problem]

[0005] In order to solve the above problems, the inventors conducted research into storm shutters that can be attached and removed, and discovered that a shock-absorbing member made up of multiple connected plate-shaped shock absorbers that can be folded has good adhesion to windows and excellent shock resistance, and thus completed the present invention.

[0006] That is, the present invention relates to an attachable and detachable storm shutter having a shock absorbing member in which a plurality of plate-shaped shock absorbers are connected and which is foldable.

[0007] It is preferable that the shock absorbers are connected in odd numbers and are foldable.

[0008] Preferably, the shock absorbing member has upper surface notches and lower surface notches alternately provided in the width direction at the connection points of the shock absorbing bodies, and is foldable in a zigzag pattern.

[0009] The width of the impact absorber is preferably 0.1 to 1.2 m.

[0010] The thickness of the impact absorber is preferably 15 to 50 mm.

[0011] It is preferable that the impact absorbing member has sheet-like fin portions at both ends to be sandwiched between the window frame and the sash.

[0012] The thickness of the fin portion is preferably 1.0 mm or less.

[0013] The fin portions are preferably provided with longitudinal mooring members for mooring the fin portions together.

[0014] Preferably, the longitudinal tether is a belt or a string.

[0015] It is preferable that at least one of the fin portions is provided with a suction cup.

[0016] The shock absorbing body preferably has a shock absorbing material inside a bag-shaped sheet.

[0017] The impact absorbing body preferably has a structure in which an impact absorbing material and a fiber cloth are laminated.

[0018] The shock absorber is preferably formed by laminating a shock absorbing material and a fiber cloth inside a bag-shaped sheet.

[0019] It is preferred that the impact absorbing material is removable. [Effects of the Invention]

[0020] The storm shutter of the present invention has a foldable shock absorbing member that is made up of multiple connected plate-shaped shock absorbers, so it adheres well to the window and has excellent shock resistance. Therefore, it can be used as a storm shutter that can be attached and removed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] The attachable and detachable storm shutter of the present invention has a shock absorbing member in which a plurality of plate-shaped shock absorbers are connected and which is foldable. Because it is a plate-shaped shock absorber, it has a certain thickness, and furthermore, due to its surface shape, it adheres well to the window, making it highly impact resistant and able to protect the window from flying objects during typhoons and other storms. Furthermore, if the impact absorbing material does not adhere well to the window and there is a gap between the window and the shutter, the shutter may be blown around by strong winds, causing it to flap and hit the window, generating noise and possibly breaking the window, and there is also the possibility that the shutter itself may be blown away. However, in this invention, the plate-like shape of the impact absorbing material provides good adhesion to the window, which prevents it from being blown around by strong winds, suppresses the generation of noise, eliminates the risk of the window breaking due to the shutter, and prevents the shutter itself from being blown away. The shock absorbing member is made up of multiple connected plate-shaped shock absorbers and is foldable, so it can be folded up and stored normally and installed in a window only when necessary, such as during a typhoon. Furthermore, if the shock absorbing material is rolled up for storage, it may take on a shape that could reduce its adhesion to the window, but in the present invention, by folding the material instead of rolling it up, the plate-shaped shock absorbing material can be stored while maintaining its plate-like shape.

[0023] A storm shutter according to one embodiment of the present invention will be described below with reference to the drawings, but the storm shutter of the present invention is not limited to the following embodiment.

[0024] 1 and 2 are perspective views that schematically show a storm shutter according to one embodiment of the present invention.

[0025] As shown in Figures 1 and 2, the storm shutter 1 comprises a foldable impact absorbing member 10 made up of multiple connected plate-shaped impact absorbers 11 (11A, 11B, 11C, 11D), sheet-shaped fin portions 20 (20A, 20B) at both ends of the impact absorbing member 10 that are sandwiched between the window frame and the sash, and longitudinal mooring members 21 (21A, 21B) that are provided on the fin portions 20 and moor the fin portions 20 together.

[0026] Figure 1 shows the shutter 1 in a state where the connection points 12 (12A, 12B, 12C) of the shock absorbers 11 (11A, 11B, 11C, 11D) are slightly folded, and Figure 2 shows the shutter 1 in a state where the connection points 12 (12A, 12B, 12C) of the shock absorbers 11 (11A, 11B, 11C, 11D) are not folded at all, i.e., in a state where it is being used as a shutter.

[0027] FIG. 3 is a cross-sectional view that schematically shows a storm shutter according to one embodiment of the present invention. The shock absorbing member 10 is made foldable by connecting four plate-shaped shock absorbers 11 (11A, 11B, 11C, 11D). The shock absorbing member 10 is formed by connecting the four plate-shaped shock absorbers 11 (11A, 11B, 11C, 11D), and the heights (lengths in the Y direction in FIG. 3) of the shock absorbers 11 (11A, 11B, 11C, 11D) are the same, and the four plate-shaped shock absorbers 11 (11A, 11B, 11C, 11D) are formed side by side with each connecting point 12 (12A, 12B, 12C) perpendicular to the width direction of the shock absorbing member 10 (X direction in FIG. 3), so that the shock absorbing member 10 has a plate-like shape. In other words, the shock absorbing member is formed by connecting a plurality of plate-shaped shock absorbers, and it is preferable that the heights of the shock absorbers are the same, each connecting point is perpendicular to the width direction of the shock absorbing member, the plurality of plate-shaped shock absorbers are formed in a row, and the shock absorbing member has a plate-like shape.

[0028] 3, the widths (lengths in the X direction in FIG. 3) of the shock absorbers 11 (11A, 11B, 11C, 11D) are the same, but in the present invention, the widths of the shock absorbers may be the same or different. In particular, it is preferable that the widths of the shock absorbers are the same because this allows for good storage when folded.

[0029] The impact absorber has a plate-like shape, and in this specification, plate-like means a shape in which the cross section having a thickness is rectangular and the thickness is thin relative to the length and width, specifically, a shape in which the cross section having the following thickness is rectangular and the thickness is thin relative to the length and width.

[0030] The width of the impact absorber (length in the X direction in Fig. 3) is preferably 0.1 to 1.2 m, more preferably 0.2 to 1.0 m. This makes it easier to install the storm shutters when attaching and removing them, and also makes them easy to store and use, as they are not too large when stored.

[0031] The thickness of the impact absorber (length in the depth direction in Figure 3) is preferably 15 mm or more, more preferably 40 mm or more, from the viewpoint of ensuring good impact resistance, and is preferably 80 mm or less, more preferably 50 mm or less, from the viewpoint of size when stored and ease of attachment and removal.

[0032] The height of the impact absorber (length in the Y direction in FIG. 3) may be set appropriately depending on the height of the window, but depending on the height of the window, it may be desirable to divide it into multiple parts in the vertical direction.

[0033] In Figures 1 to 3, the shock absorbing member 10 is made up of four plate-shaped shock absorbers 11 (11A, 11B, 11C, 11D) connected together and foldable. In the present invention, it is preferable that the shock absorbing member is made up of 2 to 10 shock absorbers (more preferably an odd number between 3 and 9) connected together and foldable. This makes it easier to install the shutters when attaching and removing them, and also makes the shutters not too large when stored, making them easy to store and use. Furthermore, by using an odd number of shock absorbers, it becomes easier to pull one end towards the other.

[0034] The shock absorbing member is made foldable by connecting a plurality of the plate-shaped shock absorbers. Therefore, the thickness (length in the depth direction in FIG. 3) and height (length in the Y direction in FIG. 3) of the shock absorbing member are the same as the thickness (length in the depth direction in FIG. 3) and height (length in the Y direction in FIG. 3) of the shock absorbing body. On the other hand, it is preferable that the width (length in the X direction in FIG. 3) of the shock absorbing member is the same as the width of the window (the width of the opening where the window is provided).

[0035] Preferably, the shock absorbing member has upper and lower notches alternately arranged in the width direction at the connection points of the shock absorbers, allowing it to be folded in a zigzag pattern. This allows the storm shutters to be folded more compactly. Here, the upper and lower notches are arranged alternately in the width direction, and it does not matter which one is arranged first. "Alternately arranging the upper and lower notches in the width direction" means that, as shown in FIG. 1, the connection points of the shock absorbers are arranged alternately on the front and back sides in the thickness direction (depth direction in FIG. 3). The connection may be detachable using Velcro (registered trademark) tape or the like.

[0036] Fig. 4 is a perspective view showing a typical folding state of a storm shutter according to one embodiment of the present invention. As shown in Fig. 4, the upper surface notches and the lower surface notches are alternately provided in the width direction at the connection points of the shock absorbing body, and the shock absorbing member can be folded in a zigzag pattern, which makes it possible to fold the shutter without any gaps.

[0037] FIG. 5 is a cross-sectional view that shows a schematic view of a storm shutter according to one embodiment of the present invention in a folded state. As mentioned above, it is preferable that the width and height of the shock absorbers are the same. In this case, as shown in Figure 5, the shutter fits well when folded and has excellent storability. In particular, it is more preferable that the shock absorbing member has the upper surface notches and the lower surface notches alternately provided in the width direction at the connection points of the shock absorbers, so that it can be folded in a zigzag pattern, and that the width and height of each shock absorber are the same. This results in a shutter with excellent storability.

[0038] In Figure 3, sheet-like fin portions 20 (20A, 20B) are provided at both ends of the width direction (X direction in Figure 3) of the impact absorbing member 10 to be sandwiched between the window frame and the sash, and the fin portions 20 (20A, 20B) are foldable at connection points 23 (23A, 23B) between the fin portions 20 (20A, 20B) and the impact absorbing member 10. Because the fin portions are sheet-like, they can be folded at any point, and of course they can be folded at the connection points with the impact absorbing member.

[0039] When the sheet-like fin portions are provided on both ends of the shock-absorbing member to be sandwiched between the window frame and the sash, the storm shutter can be easily installed on the window by sandwiching the fin portions between the window frame and the sash. For example, by using the fin portion's margin as a guide to sandwich the fin portion between the window frame and the sash, the storm shutter can be easily installed in a shape that matches the shape of the window without tilting. Furthermore, by sandwiching the sheet-like fin portion between the window frame and the sash, the storm shutter can be stably fixed and can withstand strong winds. In this specification, the term "window frame" refers to the frame of a door (door) installed in a window, and the term "sash" refers to the frame installed in an opening in a building.

[0040] The shape of the fin portion is not particularly limited, and may be a sheet-like shape that can be sandwiched between a window frame and a sash. In this specification, the term "sheet-like" means a shape having a rectangular cross section with a thickness that is thin relative to its length and width, and specifically means a shape having a rectangular cross section with the following thickness that is thin relative to its length and width.

[0041] The thickness of the fin portion (depth direction length in Figure 3) is preferably 1.0 mm or less, more preferably 0.8 mm or less, because if it is too thick, the window cannot be closed, and when it is sandwiched between the window frame and the sash, the gap between the window frame and the sash can be further reduced, thereby reducing the inflow of air and rain into the room.Although there is no particular lower limit, from the viewpoint of strength, it is preferably 0.3 mm or more, more preferably 0.5 mm or more.

[0042] The width of the fin portion (length in the X direction in Figure 3) is not particularly limited as long as it can be sandwiched between the window frame and the sash, but it is preferably 200 mm or more, more preferably 300 mm or more, and preferably 1000 mm or less, more preferably 800 mm or less, so that it can be more suitably sandwiched between the window frame and the sash and can be more easily installed when installing the storm shutters.

[0043] The height of the fins (length in the Y direction in Fig. 3) is preferably the same as the height of the impact absorbing body. That is, it is preferable that sheet-like fins are provided over the entire width of both ends of the impact absorbing member (length in the X direction in Fig. 3).

[0044] The material of the fin portion is not particularly limited as long as it is in sheet form. In addition to a sheet made of synthetic resin or rubber, the material may be a woven or knitted fabric or nonwoven fabric made of inorganic fibers such as glass fiber, silica fiber, or basalt fiber; synthetic fibers such as polyester fibers, polyvinyl chloride fibers, polyvinylidene chloride fibers, acrylic fibers, polyvinyl alcohol fibers, polypropylene fibers, or polyethylene fibers; or natural fibers such as kenaf fiber or jute fiber, coated with resin or rubber. Examples of the synthetic resin include fluororesins such as polyvinyl chloride resin (PVC), polyethylene (PE), polypropylene (PP), ethylene vinyl acetate copolymer (EVA), polyurethane (PU), polystyrene (PS), acrylonitrile butadiene styrene copolymer (ABS), polyamide (PA), acrylic resin (PMMA), polycarbonate (PC), polytetrafluoroethylene (PTFE), tetrafluoroethylene-hexafluoropropylene copolymer (FEP), tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer (PFA), tetrafluoroethylene-ethylene copolymer (ETFE), polyvinylidene fluoride (PVDF), and polyvinyl fluoride (PVF). Examples of the rubber include chloroprene rubber (CR), chlorosulfonated polyethylene rubber (CSM), natural rubber, butadiene rubber, styrene butadiene rubber (SBR), butyl rubber, acrylic rubber, urethane rubber, silicone rubber, fluororubber, and ethylene propylene rubber (EPDM). The fin portion is preferably made of a sheet having a synthetic fiber base coated with synthetic resin or rubber because of its excellent durability and flexibility.

[0045] It is preferable to provide (print) a positioning line (straight line) on the fin portion along the height direction of the fin portion (Y direction in Fig. 3). An example of the positioning line is a line that comes into contact with the window frame. When installing the shutters, by temporarily fastening them so that the positioning line comes into contact with the window frame, it becomes possible to improve convenience during temporary fastening.

[0046] It is preferable that the fin portions are provided with suction cups for temporarily fixing the fin portions to the window (window glass). If the fin portions do not have the suction cups when installing the storm shutters, even if one of the fin portions is clamped by the window frame, the door may move and the fin portion may become misaligned. However, by temporarily fixing the fin portion to the window glass with the suction cups, it becomes possible to install the storm shutters more easily. In this way, it is preferable that a suction cup is provided on at least one of the fin portions. 6 is a perspective view showing a fin portion of a storm shutter according to one embodiment of the present invention, in which a suction cup 22 is provided on the fin portion 20.

[0047] In Figure 3, longitudinal mooring members 21 (21A, 21B) that moor the fin portions 20 together are provided on the fin portions 20. The longitudinal mooring members 21 (21A, 21B) can moor the fin portions 20 together, as shown in Figures 1 and 2. FIG. 7 is a perspective view that shows a schematic view of a storm shutter according to one embodiment of the present invention attached to a window. As shown in Figure 7, the longitudinal mooring members 21 (21A, 21B) anchor the fin portions 20 together, thereby making it possible to secure the storm shutters 1 to the window. In this way, the fin portions are provided with longitudinal mooring members that anchor the fin portions together, and the longitudinal mooring members anchor the fin portions together, making it possible to secure the storm shutters to the window. Furthermore, as will be described later, providing the longitudinal mooring members to the fin portions makes it easier to install the storm shutters.

[0048] The longitudinal anchoring member is not particularly limited as long as it is a member that can anchor the fin portions together, but is preferably a belt or string, which makes it easier to attach and detach the shutters.

[0049] Next, the shock absorber will be described. The shock absorber preferably includes the shock absorbing material, and more preferably includes the shock absorbing material inside a bag-shaped sheet. This makes it possible to replace only the shock absorbing material if it is damaged.

[0050] When the shock absorbing material is contained inside the bag-shaped sheet, the shock absorbing material can be made removable by providing the bag with an opening and closing section using Velcro (registered trademark) tape or an openable zipper, for example, which makes the replacement work easier.

[0051] The bag-shaped sheet is not particularly limited as long as it has a bag-like shape and can accommodate materials, and the same sheet as that used for the fin portion can be used. Here, since the impact absorbing body is plate-shaped, the bag-shaped sheet has a quadrangular shape when viewed from above.

[0052] Examples of the impact absorbing material include flexible resins such as urethane elastomers, olefin elastomers, styrene elastomers, polyester elastomers, and soft vinyl chloride, as well as foamed plastics thereof. Among these, expanded styrene elastomers (expanded polystyrene) are preferred. The impact absorbing material is preferably formed into a plate shape.

[0053] The shock absorber preferably has a structure in which the shock absorbing material and fiber cloth are laminated, and more preferably, the shock absorbing material and fiber cloth are laminated inside the bag-shaped sheet. In this case, the breaking strength of the fiber cloth can be changed depending on the thickness of the shock absorbing material. For example, if the thickness of the shock absorbing material is 15 mm, a fiber cloth with a breaking strength of 500 kg / 3 cm or more can be used, and if the thickness of the shock absorbing material is 25 mm, a fiber cloth with a breaking strength of 300 kg / 3 cm or more can be used. In other words, by increasing the breaking strength of the fiber cloth used in proportion to the thickness of the shock absorbing material, better impact resistance can be obtained, and the thickness of the shock absorber can be made smaller, resulting in a shutter with better storage properties.

[0054] The fiber fabric may be the same as the base material used for the fin portion. Among them, a fiber fabric using polyester resin fiber is preferred from the viewpoint of durability and flexibility, and the fiber fabric may be a woven fabric, a knitted fabric, a nonwoven fabric, or the like.

[0055] The breaking strength of the fiber fabric is preferably 100 kg / 3 cm or more, more preferably 200 kg / 3 cm or more, and even more preferably 300 kg / 3 cm or more. The higher the breaking strength of the fiber fabric, the better the impact resistance that can be obtained, so there is no particular upper limit, but it is preferably 1000 kg / 3 cm or less.

[0056] The thickness of the fiber fabric is preferably 0.3 mm or more, more preferably 0.5 mm or more, and is preferably 2 mm or less, more preferably 1.5 mm or less.

[0057] FIG. 8 is a cross-sectional view schematically showing a cross section taken along line AA in FIG. In FIG. 8, a shock absorbing material 14 and a fiber cloth 15 are laminated inside a bag-shaped sheet 13 in the thickness direction of the shock absorber 11 (the depth direction in FIG. 3).

[0058] Below, an impact drop experiment was conducted to confirm the damage to the glass by dropping an impacting object (a steel piece with a piece of wood attached to the tip) shown in Table 2 from a height of 1.8 m onto a shock absorber shown in Table 1 that was placed on glass (811 mm x 1041 mm (3 mm thick)). An example of the results is shown in Table 1. Here, Styrofoam (registered trademark) was expanded polystyrene, and polyester woven fabric (breaking strength: 300 kg / 3 cm, thickness: 0.5 mm) was used as the fiber cloth. The length listed in the material column in Table 1 indicates the thickness of Styrofoam (registered trademark). Also, the items listed as "+woven fabric" have a laminated structure of impact absorbing material and fiber fabric as shown in Figure 8. [Table 1] [Table 2]

[0059] From Table 1, it was found that by having the shock absorber have a structure in which the shock absorbing material and fiber cloth are laminated (Experiment Nos. 6 to 9), better shock resistance can be obtained and the thickness of the shock absorber can be made smaller, for example, the thickness of the shock absorber can be made 30 mm or less, resulting in a shutter with better storage ability. On the other hand, when the laminated structure is not adopted, that is, when only the shock absorbing material is used, it is preferable that the thickness of the shock absorber is 35 mm or more, more preferably 40 mm or more.

[0060] Next, a method of installing the shutters shown in Figure 1 on a window (a window consisting of two sliding shutters) will be described. First, place the two doors close to the center of the sash. Then, the suction cups 22 on the fins 20A are attached to the interior side of the window glass, and one of the fins 20A is temporarily fixed to the window glass. At this time, the fins 20A are temporarily fixed so that the positioning lines on the fins 20A are in contact with the window frame.

[0061] Next, the longitudinal mooring member 21 (21A, 21B) attached to the other fin portion 20B in an untethered state is passed through the exterior side of the door and then pulled into the interior from the opposite side of the temporarily fixed side. This causes the shutter to unfold on the exterior side of the window glass.

[0062] Furthermore, by pulling the longitudinal mooring members 21 (21A, 21B) while closing the two doors, the shock absorbers 11 (11A, 11B, 11C, 11D) are opened (deployed) on the outside of the doors as shown in Figure 2. Finally, the doors are locked, and the fin portions 20 (20A, 20B) are moored together by the longitudinal mooring members 21 (21A, 21B). This allows the shutters to be installed on the windows in the state shown in Figure 7.

[0063] In Figure 7, the shutters are fixed by the fin portions and also by the longitudinal mooring members, which makes it possible to better prevent them from being blown away by strong winds, better reduce the generation of noise, reduce the risk of the shutters breaking the window, and better prevent the shutters themselves from being blown away.

[0064] On the other hand, when removing the shutters from the window, first remove the suction cups 22 from the window glass. Next, unlock the doors and move the two shutters closer to the center of the sash. Then, with the fin portions 20 (20A, 20B) anchored to each other by the longitudinal anchoring members 21 (21A, 21B), shift the shutters 1 and pull them toward the interior while folding the shock absorbers 11 (11A, 11B, 11C, 11D). Finally, release the anchoring of the fin portions 20 (20A, 20B). This allows the shutters to be folded as shown in Figure 4.

[0065] In this way, the storm shutters of the present invention can be installed inexpensively and easily on windows that do not have storm shutters installed, without the need for construction work, and are also easy to store.

[0066] The windows to which the storm shutters of the present invention can be applied are not particularly limited as long as the doors (doors) provided on the windows can be opened and closed, and examples include windows in detached houses, condominiums, apartments, buildings (particularly condominiums and apartments), etc., specifically, for example, windows with multiple sliding doors (sliding windows), windows with rotating doors (rotating or pivoting windows), windows with doors that move up and down (double-hung windows), etc. Of these, sliding windows are preferred, and French windows and waist windows are also preferred.

[0067] Furthermore, to prevent the fins from falling, particularly in the case of waist windows, it is preferable to first anchor the fins together with longitudinal anchoring members before fixing the fins to the window glass with suction cups.

[0068] Also, when used on a bay window, the shutters become large and difficult to handle, so it is preferable to use a top and bottom split type. This makes them lighter and easier to handle. However, since the bottom part must be installed first, it is recommended to use Velcro (registered trademark) to position the top and bottom.

[0069] In the above embodiment, a case has been described in which the storm shutter comprises a foldable shock absorbing member to which the plurality of plate-shaped shock absorbers are connected, the sheet-shaped fin portions sandwiched between the window frame and the sash at both ends of the shock absorbing member, and the longitudinal mooring members that are provided on the fin portions and moor the fin portions together, but in the present invention, the storm shutter may comprise a foldable shock absorbing member to which the plurality of plate-shaped shock absorbers are connected, and the longitudinal mooring members that moor the shock absorbing members to both ends of the shock absorbing member. In other words, the fin portions may not be provided.

[0070] In the above embodiment, a case has been described in which the storm shutter comprises a foldable shock absorbing member to which the plurality of plate-shaped shock absorbers are connected, the sheet-shaped fin portions that are sandwiched between the window frame and the sash at both ends of the shock absorbing member, and the longitudinal mooring members that are provided on the fin portions and moor the fin portions together, but in the present invention, the storm shutter may comprise a foldable shock absorbing member to which the plurality of plate-shaped shock absorbers are connected, and the sheet-shaped fin portions that are sandwiched between the window frame and the sash at both ends of the shock absorbing member. In other words, the longitudinal mooring members may not be provided. [Explanation of symbols]
