  The present invention relates to an inner window for a building opening that is installed on the inner side (inside the room) of an existing outer window in a building opening to enhance the heat insulating effect by doubling the shoji for windows.

In recent years, there is a growing demand to install an inner window inside a glass window at the opening of a building in order to enhance the indoor heating and cooling effect. Rather than installing a sash for heavy windows, it is often the case that only an inner window is newly installed inside an existing glass window, and it is desirable that it can be easily installed by a retrofit even if it is not a contractor. ing.
In order to meet such demands, not only the ease of installation work of the inner window is considered, but also the danger during the installation work and after use is eliminated, and the occurrence of problems in the usage state is suppressed. Sufficient consideration is necessary for this.

The technical problem of the present invention is that when installing the inner window for heat insulation inside the outer window in the existing building opening, it is not necessary to perform various processing for installing the inner window in the building opening, Even if it is not a contractor, it is providing the inner window for building openings which enabled easy installation of the inner window according to the dimension of the building opening.
Another technical problem of the present invention is that the internal window installed in the opening of the building may be damaged, the insulation effect may be reduced, and other problems may occur in normal use even if the installation is not performed by a contractor. An object of the present invention is to provide an internal window for a building opening in which there is no possibility.

  In order to solve the above-described problems, according to the present invention, an inner window for forming a double window by being installed inside an outer window in a building opening, the guide opening is provided in the building opening frame. The peripheral frame of the inner window to be mounted is configured by joining an outer frame member positioned on the four sides on the outer window side and an inner frame member disposed with a translucent plate sandwiched between them, the peripheral frame is In addition, by connecting each pair of vertical and horizontal metal outer frame members having the receiving surface of the translucent plate on the inner peripheral side of the hollow cylindrical main body portion at four corners, shape retention is imparted, The translucent plate is attached to the receiving surface of the outer frame member on the four sides thereof via a hook-and-loop fastener or a cushioning material, and the inner frame member encloses the indoor side of each of the four outer frame members. At least a pair having a form as a cover and elastically engaging around the body portion of the outer frame member A locking tongue is provided, and a flexible tongue that presses the translucent plate toward the receiving surface is provided at a portion facing the receiving surface of the outer frame member, and the locking collar and the flexible tongue are Provided is an internal window for a building opening, which is integrally formed with a synthetic resin together with an inner frame material.

  In a preferred embodiment of the building opening inner window according to the present invention, the translucent plate is attached to the receiving surface of the outer frame member with a hook-and-loop fastener, and the hook-and-loop fasteners are detachably joined to each other. It is composed of first and second fastener pieces in which a ventilation gap is formed between the joining surfaces, and the light transmitting plate is passed through the flexible tongue pieces in the inner frame material between the joining surfaces of the surface fasteners and in the inner and outer frame materials. It is configured with a sealing function that prevents airflow flowing on the opposite side.

  In another preferred embodiment of the inner window for a building opening according to the present invention, the surface fastener for attaching the translucent plate to the receiving surface of the outer frame member is a plurality of hook-shaped protrusions in the first fastener piece. And a plurality of fiber loops in the second fastener piece are formed so as to be capable of shifting in the joint surface thereof, and is attached to the receiving surface of the outer frame member by the surface fastener. The resin-made translucent plate is configured so as to be prevented from receiving stress due to a difference in thermal expansion from the vertical and horizontal metallic outer frame materials.

  The inner window for a building opening having the above-described structure is provided with a guide material, such as a nail or a screw, at the installation position of the inner window in the building opening when installing the inner window for heat insulation inside the outer window in the building opening. It is only necessary to fit a screen door frame of a predetermined size according to the size of the building opening, and it is not necessary to perform various processing for installing the internal window in the building opening. Even without this, the inner window can be easily installed.

  The assembly of the inner window itself is also performed by cutting the vertical and horizontal frame members for a metal outer frame member such as aluminum into the required dimensions and connecting them with corner members to form the outer frame member. By attaching a translucent plate to the surface via a hook-and-loop fastener, etc., and elastically engaging the translucent plate with a locking rod of the inner frame material cut to the required dimensions for each outer frame material, The assembly can be completed, and the translucent plate can be stably held against the outer frame material.

Further, the inner window itself has a peripheral frame formed by joining an outer frame member positioned on the four sides of the outer window side and an inner frame member disposed with a translucent plate sandwiched between them. The frame material is provided with shape retention by connecting vertical and horizontal frame materials made of metal such as aluminum at the four corners, and a translucent plate is attached to the receiving surface provided on the inner peripheral side of the outer frame material by a surface fastener or the like. Since it is attached, even if the light transmitting plate is inadvertently pushed from the indoor side, the light transmitting plate is stably held by the outer frame member, so that it does not come off.
Moreover, the inner frame material is made of synthetic resin having a form as a cover that encloses the indoor side of each outer frame material of the four circumferences, and the light-transmitting plate is also made of synthetic resin. Even if the temperature of the space decreases, condensation does not occur on the inner frame material on the indoor side.

  Furthermore, if the light transmitting plate is configured to be attached to the receiving surface of the outer frame member with a hook-and-loop fastener, a ventilation gap is formed between the bonding surfaces of the hook-and-loop fastener. The air on one side of the translucent plate flows between the inner and outer frame members to the opposite side and impairs the heat insulation effect, but the air flows to the flexible tongue of the inner frame member that holds the translucent plate. Therefore, the translucent plate can be effectively protected and insulated.

  In addition, there is a difference in the coefficient of thermal expansion between the metal material such as aluminum forming the outer frame material and the synthetic resin material such as polycarbonate resin constituting the light transmitting plate. Therefore, the light transmitting plate is different from the outer frame material. If the light transmitting plate is held in a fixed manner, the light transmitting plate may swell or be damaged. If the position and the posture are not restricted, it is possible to suppress the light transmission plate from being subjected to stress due to the difference in thermal expansion between the outer frame member and the light transmission plate.

  According to the building opening inner window of the present invention described in detail above, when installing the inner window for heat insulation inside the outer window in the building opening, various kinds for installing the inner window in the building opening. The inner window can be easily installed, and in normal use, the inner window installed in the building opening may be damaged or the insulation effect may be reduced. It is possible to provide an internal window for a building opening that suppresses the possibility of the occurrence of the problem.

The inner window for a building opening of this embodiment is for installing inside an existing window (outer window) in a building opening to form a double window, and a pair of windows constituting the inner window The inner window unit 1 is arranged in a sliding door shape and held on guide members 2 and 3 that fix the upper and lower frames of the building opening. The guide members 2 and 3 have the same width as that of a well-known paper sash that fits a well-known paper shoji, and the pair of inner window units 1 are built in a sliding door shape within the groove width. Therefore, each of the two grooves 2a and 3a formed in the guide members 2 and 3 has a width of about 1/2 with respect to the groove of the paper sill sill. Can be installed.

  The guide members 2 and 3 are extruded with a synthetic resin as a constant cross-sectional shape having the two grooves 2a and 3a. To fix the guide members 2 and 3 to the upper and lower frames of the building opening. The fixing bracket 5 such as a nail or a screw is driven into the frame material of the building opening through each groove bottom. In particular, the guide material 3 for fixing to the lower frame of the building opening has the groove bottom at the inner window. Since the lower end of the unit 1 slides, the sliding bottom of the groove of the guide member 3 is excellent in order to avoid contact between the head of the fixing bracket 5 and the lower end sliding surface of the inner window unit 1. The tape material 6 is laid. In addition, the guide material 4 of the same structure can be provided also in the left and right vertical frames of a building opening part as needed.

The pair of inner window units 1 mounted on the opening of the building via the upper and lower guide members 2 and 3 are formed of a metal material such as aluminum, and a pair of vertical and horizontal outer frame members positioned on the four sides on the outer window side. 1 and 12, and a corner member 30 for joining the vertical and horizontal outer frame members 11 and 12 to each other at the four corners, and a translucent plate 7 inside the vertical and horizontal outer frame members 11 and 12, as shown in FIG. A pair of vertical and horizontal inner frame members 21 and 22 made of synthetic resin and sandwiched between the corner member 30 and a screw. By firmly connecting at 31, shape retention is imparted to the inner window unit 1.
The inner window shown in FIG. 2 is installed with the left side as the outer window side and the opposite side as the indoor side.

As the vertical and horizontal outer frame members 11 and 12, as shown in FIGS. 2 and 3, mold materials having the same cross-sectional shape are used. The outer frame members 11, 12 have a hollow cylindrical main body portion 14, and the main body portion 14 is received by the translucent plate 7 that extends to the inner peripheral side of the main body portion 14 flush with the side surface of the outer window. A surface 15 is integrally formed, and a screw pocket (screw screw hole) 16 for connecting the corner member 30 to the end of the outer frame member 11, 12 with a screw 31 is formed on the inner surface of the main body 14. Is provided. Further, a rib 15a for setting a limit of movement of the light transmitting plate 7 placed thereon is protruded on the inner surface side of the receiving surface 15 so that a slight margin is generated around the light transmitting plate 7. Has been established.
When the strength of the vertical outer frame member 11 becomes a problem, a reinforcing iron plate 17 bent in a U shape as shown in FIG. In order to increase the strength of the frame members 11 and 12, as shown in FIG. 1, a reinforcing iron plate 17 may be inserted into both of them.

The translucent plate 7 is formed of a synthetic resin material plate such as polycarbonate resin, and is attached to the receiving surfaces 15 of the outer frame members 11 and 12 via the hook-and-loop fasteners 8 to attach the outer frame member. To keep it stable. The hook-and-loop fastener 8 is constituted by first and second fastener pieces attached to the light-transmitting plate 7 and the receiving surface 15 with double-sided tape, and a plurality of hook-shaped protrusions in one fastener piece and the other fastener piece. The fastener pieces are joined together by engaging a large number of fiber loops in the fastener pieces.
In addition, the hook_and_loop | surface fastener 8 can use what has not only the thing of the said structure but another structure. Moreover, it replaces with this hook_and_loop | surface fastener, and the buffer material which has rubber elasticity can also be interposed.

  On the other hand, the vertical and horizontal inner frame members 21 and 22 have a form as a cover that encloses the indoor side of the outer frame members 11 and 12, and are elastic around the main body 14 in the outer frame members 11 and 12. And at least a pair of locking rods 24 and 25 which are engaged with each other. Further, a flexible tongue piece 26 that presses the translucent plate 7 toward the receiving surface 15 side is provided on the extension portions 21a and 22a of the inner frame members 21 and 22 facing the receiving surface 15 in the outer frame materials 11 and 12. The locking rods 24 and 25 and the flexible tongue 26 are integrally formed of synthetic resin together with the inner frame members 21 and 22. The flexible tongue 26 is preferably formed by integrally molding a soft resin.

The vertical and horizontal inner frame members 21 and 22 basically have the same shape, but the space between the pair of inner window units 1 and the outer window is closed as shown in FIG. The vertical inner frame members 21 that overlap each other are usually closed by mohair or the like. However, since the inner frame member 21 is made of synthetic resin, one of the gaps between the other may be filled. By providing the flexible protrusion 27, it can be replaced with the mohair. Reference numeral 28 in FIGS. 1 and 4 indicates a handle for opening / closing operation attached to the inner frame member 21.
The flexible tongue 26 provided on the inner frame members 21 and 22 may partially interfere with the corner member 30 when it is engaged with the outer frame members 11 and 12. Will cut away unnecessary portions of the flexible tongue 26.

  Further, when the light transmitting plate 7 is left attached to the receiving surface 15 of the outer frame members 11 and 12 by the surface fastener 8, a ventilation gap is formed between the joint surfaces of the surface fastener 8. Then, through the space between the joint surfaces and inside and outside the frame material, air on one surface side of the translucent plate 7 flows to the opposite surface side and impairs the heat insulation effect, but the inner frame material 21 that holds down the translucent plate 7, Since the flexible tongue piece 26 of 22 has a sealing function for preventing the air flow, the translucent plate 7 can be effectively protected and insulated.

  Further, the metal material such as aluminum forming the outer frame materials 11 and 12 and the synthetic resin material such as polycarbonate resin constituting the light transmitting plate 7 have a difference in thermal expansion coefficient. If the outer frame members 11 and 12 are fixedly held, an internal stress may be generated in the translucent plate 7 to partially swell or break, but as described above. If the hook-and-loop fastener 8 is configured so as to be displaced within the joint surface and the position and posture of the translucent plate 7 are not restricted, the thermal expansion of the outer frame members 11 and 12 and the translucent plate 7 will occur. It is possible to suppress the translucent plate 7 from receiving stress due to the difference. Moreover, since the said surface fastener 8 has buffering property, it can avoid that damage, such as a crack, arises compared with the case where the translucent board 7 is fixed firmly.

  The inner window for a building opening having the above-described configuration is a guide with which the guide members 2 and 3 are fixed to the installation position of the inner window in the building opening with nails, screws, etc. What is necessary is just to fit a window unit, Therefore, it is not necessary to perform the various process for an inner window installation in a building opening part, Even if it is not a contractor, this inner window can be installed easily. In addition, the inner window itself is assembled by cutting vertical and horizontal frame members for a metal outer frame member such as aluminum into required dimensions and connecting them with a corner member 30 to receive the outer frame members 11 and 12. The translucent plate 7 is attached to the surface 15 via a hook-and-loop fastener or the like, and the translucent plate 7 is cut to a required size with respect to each of the outer frame members 11 and 12. , 25 can be elastically engaged to complete the assembly, so that the light-transmitting plate 7 can be stably held against the outer frame members 11, 12.
