Description

  The present invention relates to an easily attachable / detachable window heat insulator that is installed in a window frame of a building, cuts off heat from outside air, improves heating efficiency and cooling efficiency, and is used to create a comfortable space. .

  Conventional window insulators include a double sash type in which a synthetic resin sash typified by hard vinyl chloride resin used mainly in cold districts is attached to an aluminum sash, and an air layer inside the window There was a type of sticking a sheet material provided with. However, the former double sash was installed by a contractor and once installed, it could not be easily removed and was expensive, so it was mainly used in cold districts. In addition, as the latter type, for example, a heat insulating airbag for a window described in Patent Document 1 has two independent air chambers of a main air chamber 1 and a window frame fixing adjustment air chamber 2. there were.

  However, the heat insulator according to the device described in Patent Document 1 has a structure in which the air chamber 1 and the air chamber 2 are separated and independent, and the volume of each air chamber can be made variable, and the amount of air is increased or decreased to the window frame. It is tightly fixed. However, in order to make the volume of the air chamber variable by increasing or decreasing the amount of air, it is necessary that the material constituting the air chamber is soft and rubbery enough to follow the window glass. When the soft rubber elastic material is used, the form is not stable, and it is extremely difficult to fix to the window frame for a long time. In particular, when two airbags are installed side by side on the window frame, the contact surfaces of the adjacent air chambers 2 come into contact with each other between the curved surfaces, so that they are unstable and easily come off. In addition, when the air chamber 2 is filled with air, the right and left side surfaces bulge outward and the angle is rounded to form a gap, which tends to cause a decrease in the heat insulation effect.

Utility Model Registration No. 3071596

  Although the double sash has a large heat insulation effect, there is a problem in that it requires installation work and is expensive. The heat insulator according to the device described in Patent Document 1 is easier to handle than the double sash. There is room for improvement as mentioned above. The inventor of the present application has conducted extensive research on window insulators, and as a result, a plurality of suspension members having the same height as the gusset members are provided in parallel with the side surfaces inside the hollow body provided with gusset members on the peripheral edge. Thus, the present inventors have found that the hollow body is securely fixed to the window frame by the reaction force generated when pressure is applied from both side surfaces facing in parallel with the suspension member, and the present invention has been achieved. An object of the present invention is to provide a window heat insulator that solves the above-mentioned problems, can be fixed to a window frame very easily, has an excellent heat insulation effect, and is unlikely to cause deformation such as warping or sag.

  In order to solve the above-described problems, the present invention provides a window heat insulator that is easily detachable in a window frame of a building and is used to block heat from outside air. A plurality of thermoplastic resin suspension members having substantially the same width as the gusset member are disposed inside the hollow body having airtightness in which a belt-like gusset member made of thermoplastic resin is provided on the peripheral edge of the rectangular sheet member. An air port for injecting and discharging air into the hollow body while being spaced apart from each other so as to be parallel to one of the opposing side surfaces and having both end portions spaced apart from the other opposing side surface respectively. A hollow body is formed from both side surfaces parallel to the suspension member, and the top and bottom of the central portion where the suspension member is provided at the time of air filling, the top and bottom are substantially the same height. It occurs when pressing The hollow body and air mat-like window insulation device characterized by comprising pressed against fixed to the window frame by a force (claim 1).

  In order to solve the above-described problem, the present invention provides a structure in which the suspension member is formed so as to be inclined in a side view of the hollow body when the hollow body is filled with air. When the hollow body is pressed from both sides, the inclined suspension member rises in the vertical direction and the thickness increases accordingly, and the hollow body is pressed against the window frame by the reaction force acting in the opposite direction to the pressed direction. It is preferable that the window heat insulator is fixed (claim 2).

To remove, simply insert your finger into the peripheral edge and pull it toward you. A heat insulation effect of about 5 ° C. can be obtained by the difference between the outside air temperature and the room temperature. In addition, when filling with air, both sides do not swell sideways, and they are almost completely square mats, and the form is extremely stable, and warpage and settling are unlikely to occur. Since there is almost no gap at the part where the side surfaces are in contact with each other, the heat insulation effect is improved. Moreover, although the kamaboko-shaped uneven | corrugated | grooved part adjoins to a glass window, there exists an effect which reduces deterioration and dew condensation of the resin which is a raw material by interposing an air layer between a glass window and the insulator for window windows. If the suspension member is heat-sealed so as to incline when filled with air as described in claim 2 and the hollow body is pressurized from both sides and the inclined suspension member is fixed to the window frame in an upright state, It is firmly fixed to the window frame by the reaction force that acts.

Characterized by comprising securing the hollow body 1 to the window frame by the reaction force generated when pressing the wood parallel sides 17 and 17.

  The thermoplastic resin constituting the “sheet member”, “gusset member”, and “hanging member” made of thermoplastic resin is not particularly limited. For example, polypropylene (PP), polyethylene (PE), polystyrene (PS) ), Polyester (PET), polyamide (PA), polyvinyl chloride (PVC), ethylene / vinyl acetate copolymer (EVA), acrylonitrile / butadiene / styrene copolymer or blend polymer (ABS), cellulosic plastic, It can be selected according to the purpose of use from a thermoplastic elastomer or the like. Further, in addition to the single thermoplastic resin film as described above, a multilayer film bonded by dry lamination or sand lamination through a co-extruded film or an adhesive resin layer may be used. Moreover, the composite and tarpaulin of the said film and cloth thru | or a nonwoven fabric are also contained.

  Among thermoplastic resins, polyvinyl chloride (PVC) is more preferable because it can be heat-sealed by high-frequency welder processing. The polyvinyl chloride (PVC) is preferably a suspension polymer having an average degree of polymerization of P600 to P2000, and has a high repulsive force (reaction force) as a hollow body and is easily fixed to a window frame. Is particularly preferred. The addition amount of the plasticizer is 20 to 100 parts by mass, more preferably 40 to 80 parts by mass with respect to 100 parts by mass of the PVC, and it is preferable to select appropriately in consideration of the polymerization degree and hardness of polyvinyl chloride. . As the plasticizer, general-purpose DOP is preferable, and n-DOP or DIDP may be used in order to reduce the haze of the glass. In order to improve heat resistance, it is preferable to use epoxidized soybean oil together.

  Further, in order to improve the resilience and workability, it is preferable to add 5 to 20 parts by mass of a synthetic rubber, for example, NBR, and 1 to 5 parts by mass of an acrylic modifier. The sheeting process may be either a calendar or an extruder. For example, in the case of a PVC having a relatively high polymerization degree of P1300 or higher, the calendar process is preferable. Further, in order to reduce the change in the hardness of the sheet member as much as possible due to the influence of the outside air temperature, 5 to 30 parts of an inorganic filler such as calcium carbonate may be added. The sheet member is preferably transparent or translucent having translucency. The degree of transparency can be adjusted by adding an inorganic additive such as titanium oxide or calcium carbonate. A coloring material may be appropriately added or applied, and a printed pattern such as a character may be applied to the surface.

  In addition to the plasticizers, processing aids, heat stabilizers, colorants and fillers described above, flame retardants, ultraviolet absorbers, light reflectors, antifungal agents, antibacterial agents, deodorants, You may add, apply | coat, print, or surface-treat what combined 1 type, or 2 or more types of a fragrance | flavor and an antistatic agent. Phosphate flame retardants such as tricresyl phosphate (TCP) and chlorinated paraffin may be used as the flame retardant, and benzophenone, benzotriazole, and phenyl salicylate UV absorbers may be used as the ultraviolet absorber. As the light reflecting material, it is preferable to knead a metal powder such as aluminum or silver, shell powder or the like, and perform printing, coating or surface treatment. The surface treatment includes vapor deposition of aluminum or the like. An antibacterial agent such as OBPA may be used, an antibacterial agent such as an inorganic antibacterial agent in which silver ions or copper ions are supported on zeolite may be used, and an antistatic agent may be an anionic active agent, a cationic active agent, or a nonionic active agent. Various active agents such as can be used.

  Next, in the window heat insulator according to the embodiment of the present invention, a strip-shaped gusset member 12 made of a thermoplastic resin is provided in the vertical direction on the peripheral edge of the two square sheet members 11a and 11b made of the thermoplastic resin. A plurality of thermoplastic resin suspension members 13 having substantially the same height as the gusset member 12 are placed inside the hollow body 1 having high airtightness, and one of the opposing side surfaces 17, 17 of the hollow body 1. Both end portions are provided so as to be parallel to each other, and both end portions are provided at predetermined intervals from the other opposing side surfaces 18, 18. The sheet members 11a, 11b, the gusset member 12, and the suspension member 13 are preferably joined by thermal welding. Polyvinyl chloride is welded using a high frequency welder, and other resins are welded using an ultrasonic welder or an electric heater.

  The material constituting the “sheet member”, “gusset member”, and “suspending member” in the present invention includes a film and a sheet regardless of the thickness, and air is filled into a hollow body that is a heat insulator for windows. It is preferable to have flexibility and elasticity to maintain a mat-like form when pressure is applied. The thickness of the film is not particularly limited, but if the thickness is thin, fixing to the window frame becomes difficult due to a decrease in physical properties, and if it is too thick, it takes a long time for welding and causes energy loss. -2.0 mm is preferable, and 0.15-1.0 mm is more preferable.

  In order to weld the sheet members 11a and 11b and the suspension member 13, for example, as shown in FIG. 3, the surface of the suspension member 13 is welded so as to be inscribed in the sheet member 11a, and the rear surface of the suspension member 13 is the sheet member. By welding so as to be inscribed in 11b, the suspension member 13 is locked in an inclined state when the hollow body is filled with air (see FIG. 3a). When the hollow body is pressed from both side surfaces 17 and 17 parallel to the suspension member, the inclined suspension member 13 rises in the vertical direction (see FIG. 3b), and the convex portion of the kamaboko-like unevenness protrudes forward. As a result of the interval between the suspension member and the suspension member being narrowed, the hollow body expands in the thickness direction. However, since both the sheet members 11a and 11b are joined by the plurality of suspension members 13, the hollow body is securely fixed to the window frame in order to suppress expansion in the width direction and maintain a mat-like form. .

  When the window insulator is fitted vertically to the window frame, the window insulator is securely fixed to the window frame by the reaction force if the suspension member 13 is oriented substantially in the horizontal direction. It becomes a standard of. In addition, when the window insulator is attached to the window frame, a hook or an adhesive tape is attached to the hollow body so that the window insulator does not come off the window frame, and the window frame or the glass window is attached via the hook or adhesive tape. You may attach to (not shown). One or more window insulators are usually mounted side by side on a window frame. In that case, when a gap is generated between the window insulator and the window frame, the foams 19 and 19 are sandwiched between the window insulator and the window frame as shown in FIG. It is preferable to do so. The foam 19 may be made of foamed urethane, foamed styrene, foamed vinyl chloride, other resin or rubber, cut into a suitable size, and fixed with a double-sided tape or the like. The foam 19 is preferably a closed-cell sponge type in order not to lower the heat insulation.

  Although the width | variety of the gusset member and suspension member which determines the thickness of the said hollow body is not specifically limited, Usually, 15-60 mm is preferable and 20-30 mm is more preferable. If the thickness is less than 15 mm, the heat insulation effect may be insufficient, and if it exceeds 60 mm, the heat insulation effect cannot be expected to be further improved. In addition, it is preferable to prepare a plurality of types of window heat insulators of representative sizes according to the inner dimensions and depth dimensions of the window frame, and to select the window heat insulator having the size closest to the window frame. . As a size of the heat insulator for windows, for example, 375 mm × 680 mm, 390 mm × 370 mm, 390 mm × 570 mm, 617.5 mm × 370 mm, 617.5 mm × 570 mm, and a gusset width size of 20 mm or 30 mm are preferable.

Hereinafter, the present invention will be described with reference to examples. However, the present invention is not limited to these examples. First, a 0.23 mm-thick polyvinyl chloride sheet is cut into a predetermined size as a sheet member, and a sheet member, a gusset member, and a suspension member are prepared. The basic composition of the sheet member is shown below.
Formulation: Polyvinyl chloride (P1300) 100 parts by weight DOP 50 parts by weight Stabilizer (barium / zinc) 3 parts by weight

Next, a gusset member and a suspension member each having a width of 30 mm were welded to the sheet member by a high frequency welder to form a predetermined transparent hollow body. In order to weld the suspension member to the sheet member with a high-frequency welder, it is preferable to use a flat blade die having round ends at both ends. As shown in FIG. 1, when the side surface of the hollow body is pressed, both ends 14a of the heat seal part are rounded to avoid cutting due to stress concentration at the corners of the heat seal part.
(1) The suspension member in the hollow body at the time of air filling is in an inclined state (see FIG. 3a), and the size of the hollow body at this time is as follows.
Width: 375 mm, length: 755 mm, thickness (from convex part to convex part): 55.0 mm
(2) When the hollow body is pressed from both side surfaces parallel to the suspension member, the suspension member is in an upright state (see FIG. 3b), and the size of the hollow body at this time is as follows.
Width: 375 mm, length: 735 mm, thickness (from convex part to convex part): 56.5 mm

  When the window insulator is attached to the window frame, the direction in which the hollow body is arranged is not particularly limited. For example, as shown in FIGS. 4 and 5, the suspension member is arranged in the window frame so as to face the horizontal direction. Then, the hollow body is pressed and fixed to the upper and lower window frames by the reaction force. In this way, the room temperature was measured when the window insulator was attached to the window frame of the bathroom and when it was not attached. As a result, when the outside air temperature is about 3 ° C., the room temperature when the window insulator is not installed is 3 ° C. which is almost the same as the outside temperature, whereas the room temperature when the window insulator is attached. There was about 8-9 degreeC, and the heat insulation effect of the difference about 5-6 degreeC was recognized.

  The heat insulator for windows according to the present invention can be easily attached to and detached from the window frame of a building to cut off heat from the outside air to improve heating efficiency and cooling efficiency, create a comfortable space, and save energy and protect the natural environment. In addition, it is extremely useful economically.
