Description

[Technical Field]

[0001] The present invention relates to a window sheet mounting structure. More specifically, it relates to a window sheet tensioning structure and tensioning tool that can be used to attach sheets with various functions to window openings or glass that constitute windows. [Background technology]

[0002] Windows are often fitted with various types of sheets. For example, insect netting that covers the open window opening to form a screen door that prevents pests from entering, or shading sheets that are laminated onto the glass surface to limit the amount of light that enters the room, are often fitted. Advertising posters, decorative sheets, etc. are also often fitted to the inside and outside surfaces of the glass that make up the window.

[0003] Conventionally, the above-mentioned sheets have often been used in the form of screen doors, where the insect net is stretched over a separate screen door frame and held slidably in the window frame, or in the form of shading sheets, where the insect net is attached to the glass surface using adhesives, adhesive tape, etc. There is also a method of attaching the insect net using hook-and-loop fasteners.

[0004] In addition, ventilation is recommended to prevent the spread of coronavirus and other diseases, and people are opening windows more often. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2014-122545 Summary of the Invention [Problem to be solved by the invention]

[0006] Because the above-mentioned screen door is attached to a frame that is slidably mounted on the window frame sash, it cannot be installed if the window frame sash does not have a rail. In the case of a wooden window frame, it is possible to use a resin tape to hold the insect net along the edge and then clamp the insect net between the resin tape and the frame surface with nails or the like. However, this method may damage the window frame and is difficult to install in a removable manner. In recent years, mounting structures for insect nets using hook-and-loop fasteners have been developed. However, to ensure the mounting strength of the hook-and-loop fasteners, a certain width is required, which does not look very attractive. Furthermore, this method can only be applied to net-like objects.

[0007] On the upper floors of high-rise apartment buildings, screen doors are often not installed because pests do not come up. Also, because strong winds blow, high mounting strength is required for the screen door frames, etc., and screen doors designed for low-rise housing are often not applicable as they are. In particular, in office buildings, where air conditioning is assumed to be used, windows are rarely opened, and there is little need for screen doors.

[0008] However, to prevent infection with coronavirus and other diseases, there is an increased need to ensure good ventilation indoors, and even in high-rise apartments and office buildings, windows are now often opened to improve ventilation. However, opening windows on high floors can bring in strong winds and often allows strong light to shine directly into the room.

[0009] The present invention was devised to solve the above-mentioned problems, and allows an insect net to be installed on windows that are not equipped with screen doors, etc. Another object of the present invention is to provide a window sheet mounting structure that allows various sheets to be installed on windows not only in the open state but also in the closed state. [Means for solving the problem]

[0010] The present invention is a window sheet mounting structure using a sheet extension tool. The sheet extension tool is configured with a base member that is attached to a window component, a window frame, or the vicinity thereof, and a holding member that is detachably fastened to the base member and can hold the sheet member between the base member and the base member. The base member has one surface that is attached to the window component, the window frame, or the vicinity thereof. , formed in a long rectangular shape having a predetermined width a plate-shaped mounting portion and a plate-shaped mounting portion on the other surface of the plate-shaped mounting portion; , along the busbar integrally formed columnar On the other hand, the holding member is configured to hold the sheet member between the holding member and the fastening portion, Elastically attach to the fastening part It is fastened detachably, a long groove-shaped fastening portion having an inner surface corresponding to the outer surface of the fastening portion; Equipped with a holding portion. In a cross-sectional configuration in which the holding member is fastened to the base member without holding the sheet, the fastening portion and the holding portion are configured so that the radial gap between the vicinity of the neck portion extending from the base member of the fastening portion and the edge of the holding portion is smaller than the radial gap between the top of the fastening portion and the inner surface of the holding portion opposite it. The sheet extension tools are provided at predetermined intervals, and the edges of the sheet are fastened to the sheet extension tools, so that the sheet is extended so as to cover part or all of the window opening.

[0011] There are no particular limitations on the type or structure of the window to which the sheet is attached, as long as there is a location to which the tensioning tool of the present invention can be attached. Various sheets can be stretched over any type of window, including sliding windows, sliding windows, inward-opening windows, outward-opening windows, casement windows, projection windows, louvered windows, awning windows, skylights, and French windows. Furthermore, insect netting can also be installed not only on windows but also on ventilation fan openings, vent holes, etc.

[0012] There are also no particular limitations on the materials used to construct the window itself or the window frame. It can be applied to windows with aluminum sashes, wooden sashes, resin frames, etc. Furthermore, by placing it over a screen door, it is also possible to provide a shading sheet or windbreak sheet.

[0013] Furthermore, there are no particular limitations on the window components, and insect netting or windbreak sheets can be provided not only on glass or acrylic windows but also on breathable shutters and the like.

[0014] The type of sheet to be stretched is not particularly limited. For example, the window sheet may be an insect net, a light-blocking sheet, a heat-insulating sheet, a windproof sheet, etc. Also, a sheet printed with advertising that functions as a signboard may be stretched on the inside and outside surfaces of the glass of the window component.

[0015] The material of the sheet is not particularly limited, and may be a knitted sheet such as an insect net, a resin sheet, a paper sheet, a cloth sheet, or the like.

[0016] The installation position of the sheet is not particularly limited, and it can be installed to cover all or part of the window. Furthermore, the required sheet can be installed regardless of whether the window is open or closed. For example, in the case of a sliding window, an insect net can be installed to cover the opening when the window is in the required open position. Furthermore, when the window is closed, a shading sheet or the like can be easily installed on the glass surface, which is a window component.

[0017] For example, insect nets and windbreak sheets (windbreak nets) can be stretched over the open parts of the window. Also, shading sheets can be installed regardless of whether the window is open or closed, and can be stretched only over areas that prevent sunlight from entering the room. For example, in the case of glass windows, they can be stretched only over the top. Shading sheets that prevent people from looking in from outside can also be installed only over necessary areas. Advertising sheets can be stretched on the inside and outside of glass panes so that they can be seen from outside when the window is closed.

[0018] The sheet extension tool according to the present invention comprises a base member attached to a window component, a window frame, or the vicinity thereof, and a holding member removably attached to the base member to hold a sheet member between the base member and the base member. The materials constituting the base member and the holding member are not particularly limited. For example, they can be made of various resin materials or metals. The base member and the holding member can also be made of different materials.

[0019] The base member has a plate-shaped mounting portion on one side that is fastened to a window component, the window frame, or the vicinity thereof, and a fastening portion integrally formed on the other side. Meanwhile, the holding member has a holding portion that is elastically fitted into the fastening portion while sandwiching the sheet member. By adopting this configuration, not only can the sheet extension tool be constructed with a minimum number of parts, but the sheet can also be fastened extremely easily.

[0020] To securely hold a sheet with low strength or that is easily deformed, it is preferable to hold it over a certain length. In particular, in the case of insect netting, if it is held at one point or over a small holding area, the netting threads may become displaced, causing the mesh openings to become larger or the threads at the edges to become frayed.

[0021] In the present invention, the base member and the holding member are preferably formed in a long shape having a predetermined length. The holding portion, having a length corresponding to the length of the fastening portion, is preferably configured to be elastically fitted to the fastening portion, which has a predetermined length provided in the longitudinal direction of the base member, while sandwiching the edge of the sheet member by a predetermined length. The length of the fastening portion is not particularly limited and can be set depending on the type of sheet. For example, in the case of an insect net, it is desirable to configure it so that it can be fastened to a length of 3 cm or more, preferably 4 cm or more.

[0022] In the present invention, The base member but The mounting member is configured to include a plate-shaped mounting portion formed in a long rectangular shape having a predetermined width, and a column-shaped fastening portion integrally formed in the longitudinal direction of the plate-shaped mounting portion along a generatrix. will be done. On the other hand, the holding member but The sheet member is configured with a long groove-shaped holding portion that can be elastically fitted from the side to the column-shaped fastening portion, thereby allowing the edge of the sheet member to be clamped and held between the fastening portion and the holding portion over a predetermined length. In a cross-sectional configuration in which the holding member is fastened to the base member without holding the sheet, the fastening portion and the holding portion are configured so that the radial gap between the vicinity of the neck portion extending from the base member of the fastening portion and the edge of the holding portion is smaller than the radial gap between the top of the fastening portion and the opposing inner surface of the holding portion. With this configuration, when tension acts on the sheet, the greatest tension acts on the area sandwiched between the vicinity of the neck portion of the fastening portion and the edge of the holding portion. This makes it possible to securely hold the sheet.

[0023] The lengths of the base member and the holding member are set to the predetermined lengths described above in advance. Alternatively, the base member may be constructed by cutting a continuous molded article having the cross-sectional shape of the base member to the predetermined length described above, and the holding member may be constructed by cutting a continuous molded article having the cross-sectional shape of the holding member to the predetermined length described above. This configuration allows application to the various sheets mentioned above, window members of various shapes and sizes, and the like.

[0024] The cross-sectional shape of the fastening portion is not particularly limited, and polygonal, circular, etc. can be adopted. The holding portion may have any shape as long as it can be elastically fitted to the fastening portion. A gap is set between the outer surface of the fastening portion and the long groove so that the sheet member can be held with a predetermined strength. The size of the gap is set depending on the thickness of the sheet to be held, etc. Furthermore, it is preferable to provide anti-slip irregularities on the outer surface of the fastening portion and the inner surface of the long groove. The shape of the irregularities is not particularly limited, and they can be provided in parallel lines extending in the longitudinal direction, or can be configured by providing protrusions at predetermined intervals.

[0025] The method for attaching the base member to the window frame or the like is not particularly limited. For example, the base member can be configured to be attached via an adhesive layer provided on the back side of the base member. Alternatively, the base member can be configured to be fixed with nails or screws. [Effects of the Invention]

[0026] Not only can an insect net be installed on a window or the like that is not provided with a screen door, but various sheets can also be stretched on the window. [Brief explanation of the drawings]

[0028] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0029] As shown in Figure 1, for ease of understanding, the mounting structure 1 according to this embodiment uses the sheet extension tool of the present invention to extend an insect net over the entire surface of a conventional screen door frame 6. Note that a typical screen door frame has grooves formed in it for extending the net, and the insect net is usually extended by sandwiching the insect net in the groove and pushing a pressure rubber into it.

[0030] In this embodiment, the sheet extension tools 2 are installed at predetermined intervals on the surface of the screen door frame 6, and the insect net 5 is installed by fastening the edges of the insect net 5 to these sheet extension tools 2. There are no restrictions on the intervals at which the sheet extension tools 2 are installed, but it is preferable to install them at intervals of 30 cm or less.

[0031] As shown in Figures 2 to 5, the sheet extension tool 2 is composed of a base member 3 that is attached to the surface of the screen door frame 6, and a holding member 4 that cooperates with this base member 3 to hold the insect net 5.

[0032] The base member 3 includes a plate-shaped mounting portion 12 that is attached to the screen door frame or the like, and a fastening portion 11 that is integrally formed with the plate-shaped mounting portion 12. The base member 3 and the holding member 4 are formed entirely from resin and are formed into a long shape having a predetermined length. There are no particular limitations on the materials that make up the base member 3 and the holding member 4. Since they are often exposed to sunlight, it is preferable to form them from a highly weather-resistant resin material. For example, they can be manufactured using vinyl chloride resin, polyethylene resin, polycarbonate resin, etc.

[0033] The holding portion 16 of the holding member 4, which has a length corresponding to the length of the fastening portion 11, is elastically fitted onto the fastening portion 11, which has a predetermined length provided in the longitudinal direction of the base member 3, with the holding portion 16 sandwiching the edge of the insect netting 5 by a predetermined length. This makes it possible to hold the edge of the insect netting 5 at a required length, preventing fraying of the threads constituting the net and ensuring that the insect netting 5 is fastened securely. The length of the base member 3 and the holding member 4 in this embodiment is set to about 5 cm, but it is preferable to set the length to at least 3 cm or more, preferably in the range of 4 to 7 cm.

[0034] The fastening portion 11 is formed in a cylindrical shape that extends in the longitudinal direction of the plate-shaped mounting portion 12 and is integrally formed along a generatrix on the surface of the plate-shaped mounting portion 12. On the other hand, the holding portion 16 is composed of a long groove having an inner surface shape that corresponds to the outer surface shape of the fastening portion 11, and is configured so as to be elastically fitted to cover the fastening portion 11 with the sheet member sandwiched therebetween.

[0035] The retaining member 4 is configured so that the inner diameter of the retaining portion 16 can elastically expand when fitted into the fastening portion 11, and is configured so that the insect net 5 can be elastically fitted by being pushed into the fastening portion 11 while sandwiching it. Furthermore, parallel linear irregularities 13, 17 extending in the longitudinal direction are provided on the outer peripheral surface of the fastening portion 11 and the inner peripheral surface of the retaining portion 16. The provision of the irregularities 13, 17 prevents the insect net from slipping and allows it to withstand the required tension.

[0036] A method for installing a sheet extension tool according to an embodiment will be described with reference to FIGS. 1 and 6 to 8. FIG.

[0037] As shown in Figures 1 and 6, the base members 3 are attached to the surface of the screen door frame 6 at a predetermined interval. There are no particular restrictions on the interval at which the base members 3 are installed, but in the case of an insect net 5, it is preferable to install them at intervals of 30 cm or less. Furthermore, because large forces are often applied to corners, it is preferable to set the interval between adjacent base members 3 narrower than the above interval. Double-sided adhesive tape with its adhesive surface covered with release paper is affixed to the mounting surface of the plate-shaped mounting portion 12 of the base member 3, and the release paper is peeled off and the base member is attached to the surface of the screen door frame 6 at a predetermined interval so as to cover the opening of the frame.

[0038] As shown in Figure 8, the insect netting 5 is placed so as to cover the opening of the screen door frame 6 and overlap the sheet extension tool, and with the required tension applied, the holding portion 16 of the holding member 4 is fitted into the fastening portion 11 of the base member 3. This connects the insect netting 5 to the screen door frame 6, and the insect netting 5 is stretched over the opening of the screen door frame.

[0039] As shown in Figure 7, the fastening portion 11 of the base member 3 and the holding portion 16 of the holding member 4 have parallel linear projections and recesses in the longitudinal direction, which allows the insect net 5 to be held with the required strength.

[0040] Furthermore, as shown in Fig. 9, in the gap between the outer periphery of the fastening part 11 and the inner periphery of the holding part 16 according to this embodiment, which accommodates the insect net 5, the clamping pressure is set to be maximum at the part where the insect net 5 extends. In a cross-sectional view in which the holding part 16 is fastened to the fastening part 11 in a state in which the insect net is not held, The dimension of the gap H2 near the neck of the fastening part 11 is set to be smaller than the value of the gap H1 near the top of the holding part of the fastening part 11. The dimensions of H1 and H2 are not particularly limited and can be set depending on the thickness of the sheet, etc.

[0041] When tension acts on the insect netting 5, the greatest tension acts on the mating edge of the fastening part 11 and the holding part 16 of the sheet extension tool 2, i.e., the area clamped by part H2. For this reason, if the holding force in this area is weak, the holding member 4 will elastically deform, widening the gap H2 at the edge and causing the insect netting 5 to loosen or come off. By setting the elastic clamping pressure in the opposing areas of the fastening part 11 and the holding part 16 that fasten the insect netting 5, it is possible to hold the insect netting 5 securely.

[0042] In this embodiment, the length of the sheet extension tool 2 is set to 5 cm, but if the length of the plate-like mounting part is longer, there is a risk of deformation during molding or long-term use. For this reason, in this embodiment, a V-groove is provided on the surface of the plate-like mounting part 12 to prevent the deformation.

[0043] 10 to 12 show various seat mounting configurations.

[0044] The embodiment shown in Figure 10 shows an insect net 35 installed on a window that does not have a screen door. As shown in this figure, one of the glass doors of a sliding window is opened to a predetermined width, and the insect net 35 is installed to cover this opening 30.

[0045] The embodiment shown in Figure 11 shows a case where a shading sheet 25 is stretched over the top of the glass door. As shown in Figure 11, the shading sheet 25 can be provided in a required portion 40 of the glass door.

[0046] The embodiment shown in Figure 12 shows a case where an advertising sheet 35 is stretched over the glass of a transparent glass window. As shown in this embodiment, the advertising sheet can be easily installed because there is no need to apply adhesive to the entire surface of the advertising sheet or to fix the edges with adhesive tape or the like.

[0047] 13 to 15 show an embodiment in which the holding member 104 is provided with operation sections 201 and 202 for facilitating attachment and detachment.

[0048] 13 and 14, the operating parts 201, 202 are configured by providing a plate-like protrusion of a predetermined width in the center of the outer surface of the holding member 104. By providing the operating part, it becomes possible to easily attach and detach the fastening part.

[0049] 15, the axial length of the holding member 4 is set to be longer than the length of the base member, so that the end of the holding member 4 extending from the base member becomes the operation portions 201, 202. By adopting this configuration, it becomes possible to clamp the end of the holding member 4 and perform the attachment / detachment operation.

[0050] Figure 16 1 shows an example in which a sheet can be stretched using a conventional screen door frame. Conventional screen door frames have grooves around the entire periphery for installing insect netting. This embodiment utilizes these grooves to allow installation of not only insect netting but also various other sheets.

[0051] In the widely used screen door frame To replace a damaged insect net, place the insect net in the groove of the screen door frame and press down the rubber. In the groove above It is necessary to push it in. To ensure that the retaining rubber is pushed in securely, the screen frame needs to be placed on a horizontal surface. However, in apartment buildings and other such buildings, there is often no space to place the screen frame horizontally. This makes it difficult to replace the screen, and people often continue to use nets with holes in them.

[0052] In this embodiment, in the case described above, a sheet mounting tool that can stretch an insect net or the like using a screen door frame is shown. etc. The fastening structure for fastening the sheet tensioner to the sheet tensioner according to this embodiment is the same as that of the above-described embodiment, and therefore a description thereof will be omitted.

[0053] above As in the embodiment described above, the sheet attachment device can be provided on the flat surface of the screen door frame, but by utilizing the groove, it is possible to provide a strong and attractive insect screen. etc. can be attached.

[0054] FIG. 16 shows a cross-sectional view of a sheet extension tool 512 according to this embodiment. The length and other features of the sheet extension tool 502 are the same as those of the above-described embodiment. The base member 503 according to this embodiment is provided with a plate-shaped mounting portion 512, one surface of which is attached to the window component, the window frame, or the vicinity thereof, and a locking protrusion 505 extending perpendicularly from an edge formed on one side edge of the plate-shaped mounting portion 512. The locking protrusion 505 can be provided along the entire length of the side edge, or can be provided intermittently at predetermined intervals. When provided intermittently, it is preferable to provide the locking protrusions 505 so as to include the vicinity of the longitudinal end of the plate-shaped mounting portion 512.

[0055] The locking protrusion 505 is set to a length that allows it to enter the groove 506c of the screen door frame 506. In this embodiment, the surface of the inner edge 506b of the screen door frame 506 is formed in a stepped shape that is a predetermined height lower than the outer surface 506a. In the sheet extension tool 502 of this embodiment, the plate-shaped mounting portion 512 is fixed to the outer surface 506a via double-sided adhesive tape 550, and the outer surface 505a of the locking protrusion 505 is abutted against and locked to the inner edge 506d of the groove 506c.

[0056] In the above embodiment, the outer surface 505a of the locking protrusion 505 is brought into contact with the inner edge 506d of the groove 506c, so that the tension of the insect net 5 can be supported by the inner edge 506d of the groove 506c. Therefore, even if the adhesive strength of the adhesive tape 550 is low, it can withstand the tension acting from the insect net 5. Furthermore, the sheet extension tool 502 can be arranged in a straight line along the groove 506c. Therefore, it is possible to tension the insect net in a way that looks good, similar to when tensioning the insect net in the groove 506c using a pressure rubber.

[0057] In this embodiment, the groove 506c is configured to be engaged only with the inner edge thereof, but it may also be configured to elastically abut on both the inner and outer edges of the groove 506c.

[0058] Furthermore, even when the screen door frame does not have a stepped portion, the sheet extension tool can be provided so that the locking protrusion 505a is aligned along the inner edge of the screen door frame.

[0059] The present invention is not limited to the above-described embodiment. In the embodiment, a sheet extension tool having a predetermined length is used, but the lengths of the base member and the holding member may be set to the predetermined length in advance. The base member can be constructed from a molded article obtained by cutting a continuous molded article having the cross-sectional shape of the base member to the predetermined length described above, and the holding member can be constructed from a continuous molded article having the cross-sectional shape of the holding member to the predetermined length described above. This configuration makes it possible to apply the various sheets described above and window members of various shapes and sizes. [Industrial Applicability]
