Background Technology

[0003] Insulated windows refer to windows with excellent heat-blocking capabilities that prevent external heat or cold from entering the interior. They are widely used in homes, offices, schools, and government buildings for energy conservation, maintaining a comfortable indoor environment, preventing condensation, and blocking noise.

[0004] Typically, insulated windows consist of multi-layer glass, which enhances thermal insulation performance by placing air or argon gas between two or more panes of glass, and frames made of materials such as PVC or aluminum; various research and development efforts are being conducted regarding the structure, installation methods, and finishing treatments of windows to improve thermal insulation and ease of installation.

[0005] For example, to improve constructability, there is growing interest in modularizing window structures, applying structural designs for easy construction, and using lightweight materials; meanwhile, to enhance thermal insulation, the application of Low-E coating to double-pane glass, airtight sealing, and thermal insulation designs are being considered.

[0006] However, despite such interest and research and development, there were limitations in fundamentally resolving the problems of reduced thermal efficiency caused by easy internal-external heat exchange through the window frame and the difficulty of construction. The problem to be solved

[0044] The above-mentioned insulating members (120, 130 and 170) may be made of a polyamide material with excellent insulating performance, and the remaining components may be made of aluminum.

[0045] The above main frame (110) has a rectangular hollow formed inside and may have a rectangular cross-section having a symmetrical structure with respect to the horizontal centerline (HCL).

FIG. 13 is an actual photograph showing the combined state of the connection plate (160) and the third insulation member (170) of the insulating window (100) according to the first embodiment.

[0050] The main frame (110) may include a first horizontal surface (111), a second horizontal surface (112), a first vertical surface (113), and a second vertical surface (114). A pair of vertical extensions (115 and 116) into which the first insulating member (120) is fitted may be provided at both ends of the first horizontal surface (111).

[0051] The first vertical surface (113) is a surface corresponding to the outdoor direction (i.e., the outdoor side) of the insulating window (100), and the second vertical surface (114) may be a surface corresponding to the indoor direction (i.e., the indoor side) of the insulating window (100).

[0052] The first insulating member (120) is fitted into the first locking part (115A) of the vertical extension part (115 and 116) provided at both ends of the first horizontal surface (111), and can come into contact with the first horizontal surface (111).

[0053] The first end cap (140) is fitted into a second locking part (121) provided on the first insulation member (120) and can come into contact with the first insulation member (120).

[0054] In this specification, the term 'contact' of the components of the insulating windows (100) may mean that they are located close to each other and can be in close contact or in contact.

[0055] Each of the second insulation member (130) and the second end cap (150) can be attached to the second horizontal surface (112) of the main frame (110) so as to be vertically symmetric with respect to the horizontal centerline (HCL) with respect to the first insulation member (120) and the first end cap (140). Therefore, a detailed description of these is omitted.

[0056] The above connecting plate (160) can be fastened to the first vertical surface (113) on the outdoor side of the main frame (110). The third insulating member (170) can be connected to the connecting plate (160) and extended in the horizontal direction.

[0057] The third end cap (180) can be fitted into the end of the third insulation member (170). The vertical length of the third end cap (180) can correspond to the state in which the insulation members (120 and 130) and the end caps (140 and 150) are mounted on the main frame (110).

[0058] Above, we have examined the combination relationship of the components of the above-mentioned thermal insulation window (100). Below, we will examine in more detail the inherent unique structural characteristics of each component and the resulting effective aspects.

[0059] First, let's look at the above-mentioned vertical extensions (115 and 116).

[0060] The above-mentioned vertical extensions (115 and 116) can easily be fitted together with the insulating members (120 and 130) and can contribute to stably supporting the end caps (140 and 150) fitted together with the insulating members (120 and 130).

[0061] Since the above-mentioned vertical extensions (115 and 116) have a symmetrical structure except for some structures, we will examine their structure and function with a focus on the vertical extension (115) on the outdoor side among the above-mentioned vertical extensions (115 and 116), and then examine the differences between them.

[0062] The above vertical extension (115) may include a first horizontal surface (115B), a first inclined surface (115C), a first vertical surface (115D), and a second inclined surface (115E) formed inwardly from the top at the same height as the first end cap (140).

[0063] The first horizontal plane (115B) is formed at the same height as the first end cap (140) and is formed on the inside at the upper end of the vertical extension (115). In the following, "inside" may mean a direction toward the vertical centerline (VCL) of the main frame (110), and "outside" may mean a direction away from the vertical centerline (VCL).

[0064] The first inclined surface (115C) is formed by extending from the first horizontal plane (115B) and contacts the corresponding inclined surface (141) formed on the first end cap (140). The angle of inclination of the first inclined surface (115C) relative to the horizontal centerline may be 45 degrees.

[0065] Therefore, the first end cap (140) can be connected to the first insulation member (120) at the same height as the first horizontal plane (115B), and its end can be supported by the first inclined plane (115C) to achieve a stable connection state.

[0066] The first vertical surface (115D) is formed by extending from the first inclined surface (115C), and the second inclined surface (115E) may be formed by extending inward from the first vertical surface (115D). The first insulating member (120) may slide in contact with the second inclined surface (115E) and then be fitted into the first locking part (115A) formed by the second inclined surface (115E).

[0067] Since the first inclined surface (115C) supports the first insulating member (120) and the second inclined surface (115E) is for easy sliding of the first insulating member (120), it is preferable that the inclination of the second inclined surface (115E) be greater than the inclination of the first inclined surface (115C).

[0068] For example, the angle of inclination of the first inclined surface (115C) may be 45 degrees relative to the horizontal centerline (HCL), and the angle of inclination of the second inclined surface (115E) may be in the range of 50 to 70 degrees relative to the horizontal centerline (HCL).

[0069] The horizontal length of the second inclined surface (115E) may be the same as that of the first inclined surface (115C), but considering the difference in slope, the vertical length of the second inclined surface (115E) may be longer than the vertical length of the second inclined surface (115E).

[0070] Below the above-mentioned vertical extension (115) on the outdoor side, a groove (115F) is further formed to which a multilayer glass (MLG) support member (190) is joined. Therefore, unlike the above-mentioned vertical extension (116) on the indoor side which is formed by extending directly from the second vertical surface (114), the above-mentioned vertical extension (115) on the outdoor side is formed further outward than the first vertical surface (113).

[0071] Next, we examine the first and second insulating members (130 and 140) mentioned above.

[0072] For reference, since these are symmetrical in the vertical direction with respect to the above horizontal centerline (HCL), the characteristics thereof are explained with respect to the above first insulating member (120).

[0073] The first insulating member (120) may include a first surface (122), a plurality of vertical reinforcing members (123), a second surface (124), a pair of second vertical reinforcing members (125), a second horizontal surface (126), a second vertical surface (127), and a first locking member (128).

[0074] The first surface (122) may be in contact with the first horizontal surface (111) of the main frame (110). The plurality of first vertical reinforcing members (123) may be provided in the first section (S1) in the center of the first surface (122).

[0075] The first section (S1) is a section that is symmetrical to the left and right of the vertical centerline (VCL), and the plurality of first vertical reinforcing members (123) can also be arranged symmetrically to both outer directions of the vertical centerline (VCL).

[0076] The second surface (124) is connected to the plurality of first vertical reinforcing members (123) to cover the first section (S1) and can come into contact with the first end cap (140). A closed first insulation space (IS1) can be formed between the first surface (122) and the first end cap (140) by the second surface (124).

[0077] The above pair of second vertical reinforcing members (125) are provided on both outer sides of the first section (S1) at the same height as the second surface (124), and between them, the second locking member (121) for the first end cap (140) to be locked and connected may be formed.

[0078] The second locking portion (121) may be formed by a third horizontal plane (125A) extending oppositely from each of the pair of second vertical reinforcing portions (125) and a third inclined plane (125B) extending oppositely from the third horizontal plane (125A).

[0079] The third inclined surface (125B) is a part where the locking member (142) of the first end cap (140) slides, and can contribute to the first end cap (140) being easily fitted together.

[0080] In the second section (S2) between the first section (S1) and the pair of second vertical reinforcing members (125), an open second insulation space (IS2) may be formed between the first surface (122) and the first end cap (140).

[0081] Meanwhile, the closed first insulation space (IS1) examined is intended to provide structural rigidity that can prevent bending caused by the improvement of insulation performance and the thin and wide structural limit, and the open second insulation space (IS2) is intended to contribute to insulation performance while having relatively weak structural rigidity so that the first insulation member (120) can be easily fitted and coupled to the vertical extension (115 and 116).

[0082] To achieve this purpose, it is preferable that the width of the first section (S1) be greater than the sum of the widths of the second sections (S2) on both sides. For example, the width of the first section (S1) may occupy at least 50% to 70% of the total width of the first insulation member (120).

[0083] The second horizontal plane (126) may extend outward from the upper end of the outer second vertical reinforcing member of the pair of second vertical reinforcing members (125). The second vertical plane (127) may be formed by extending from the second horizontal plane (126), and the first locking member (128) may be formed by extending from the second vertical plane (127) outward in the horizontal direction.

[0084] Meanwhile, in FIG. 8, the end of the first locking member (128) drops vertically in the longitudinal direction, and this structure may not be suitable for sliding down the second inclined surface (115E).

[0085] In order to improve this so that the first locking member (128) of the first insulating member (120) can be easily slid on the second inclined surface (115E), in another embodiment of the present invention, the end of the first locking member (128) may be implemented to be inclined in a direction corresponding to the second inclined surface (115E), as shown in FIG. 9.

[0086] In addition, as another structural feature for easy fitting into the vertical extension (115), the second horizontal plane (126) of the first insulating member (120) is thinner than the first plane (122). This may be to make the second horizontal plane (126) thin so that the necessary degree of bending can easily occur when the first locking member (128) slides along the second inclined plane (115E).

[0087] And in order to provide strong support against bending force of the second horizontal plane (126), it is preferable that the outer one of the pair of second vertical reinforcing members (125) is thicker than the inner one.

[0088] Next, we examine the first end cap (140) and the second end cap (150) and the features of how they are combined with the first insulation member (120) and the second insulation member (130).

[0089] For reference, since these are symmetrical in the vertical direction with respect to the above horizontal center line (HCL), the characteristics thereof are explained with respect to the above first end cap (130).

[0090] The first end cap (140) may include a third surface (142) formed at both ends with a corresponding inclined surface (141) that contacts the first inclined surface (115C) of the vertical extension (115), and a second locking member (143) that is fitted into the second locking part (121) of the first insulation member (120).

[0091] The second locking member (143) may include a column (144) extending from the second surface (142) and a wedge (145) formed at the end of the column (144). The wedge (145) may slide on the third inclined surface (125B) and be fitted into the second locking part (121).

[0092] It is preferable that the slope of the third inclined surface (125B) be greater than the slope of the wedge surface. This may be for easy fitting. At this time, it is preferable that the width of the outer second vertical reinforcing member among the pair of vertical reinforcing members (125) be wider than the width of the inner second vertical reinforcing member. This may be because the outer second vertical reinforcing member provides support against bending of the first insulating member (120).

[0093] Meanwhile, the width of the wedge (145) may be 0.5 mm to 1.5 mm wider than the shortest distance between the third inclined surfaces (125B), and it may be preferable that each side of the wedge (145) engages with the second catch by at least 0.5 mm. This may be done to ensure minimum coupling stability and allow for easy removal once the wedge (145) is fitted into the second catch (121).

[0094] Finally, we examine the structure and bonding characteristics of the connecting plate (160) and the third insulating member (170).

[0095] The above connecting plate (160) can be screw-fastened to the first longitudinal surface (113) of the main frame (110) while the third insulating member (170) is pressed and joined. To indicate the location of the screw fastening and to facilitate the joining process, a pair of screw grooves (161) are provided on the outer side of the connecting plate (160) at positions symmetrical with respect to the horizontal centerline (HCL).

[0096] In addition, a pair of screw grooves (113A) are formed on the outer side of the first vertical surface (113) at the same vertical position as the pair of screw grooves (161). This may be for ease of screw joining.

[0097] Since the third insulating member (170) is fixed to the connecting plate (160) by pressure rolling in the fitting groove (162), the third insulating member (170) is screw-coupled to the first vertical surface (113), so the working time can be reduced and the work can be made easier.

[0098] The third insulating member (170) can be fastened to the first longitudinal surface (113) with a piece while being inserted into a receiving groove formed by a step (113B) extending from the first longitudinal surface (113). Therefore, the fixing work of the third insulating member (170) can be made easier.

[0099] The above-mentioned groove (162) may include a pair of horizontal extensions (162A), a vertical finish surface (162B), and three protruding members (162C).

[0100] The above pair of horizontal extensions (162A) may be vertically extended outward from the connecting plate (160) at a vertically symmetrical position relative to the horizontal centerline (HCL). The vertical finishing surface (162B) may connect the ends of the above pair of horizontal extensions (162A).

[0101] The three protruding members (162C) can form a pair of interlocking grooves (162D) in the horizontal direction on the vertical finishing surface (162B). A closed third insulation space (162E) can be formed between the vertical finishing surface (162B) and the connecting plate (162A) to improve insulation performance.

[0102] For reference, FIG. 12 shows the state in which the connecting plate (160) and the third insulating member (170) are simply arranged and combined before being pressure-rolled, and FIG. 13 shows the state in which the third insulating member (170) is fixed to the connecting plate (160).

[0103] In the case of FIG. 13 compared to FIG. 12, it can be seen that among the three protruding members (162C), the protruding members (162C1 and 162C2) on the vertical outer side are pressed in the direction of the horizontal centerline (HCL) by pressure rolling, thereby strongly fixing a pair of interlocking members (171) of the third insulating member (170).

[0104] Meanwhile, the third insulation member (170) may include a plurality of closed fourth insulation spaces (173) formed sequentially in the horizontal direction by dividing the space between the two horizontal plates (172) in the vertical direction.

[0105] The plurality of fourth insulation spaces (173) are characterized by having a wider horizontal width as they extend outward. This may be intended to improve insulation performance by securing a wider insulation space closer to the outer side of the horizontal direction.

[0106] FIGS. 14 and FIGS. 15 are an exploded perspective view and an assembled perspective view viewed from a cross-sectional view of an insulating window (100') according to a second embodiment of the present invention.

[0107] The above-mentioned insulating window (100') is similar to the insulating window (100) according to the first embodiment of the present invention described above, but differs only in some components; therefore, the description of the commonalities is omitted below, and the features of the above-mentioned insulating window (100') are examined focusing on the differences.

[0108] The above-described insulating window (100') is characterized by including a different connecting plate (160') and a third insulating member (170') compared to the insulating window (100) according to the first embodiment of the present invention, and not including a third finishing cap (180).

[0109] The above connecting plate (160') is fastened to the main frame (110) with a piece, but there is a difference in the connection portion where the third insulating member (170') is fixed, and the third insulating member (170') also has a difference in the portion corresponding to the connection portion of the connecting plate (160'). In addition, the third insulating member (170') also includes a plurality of insulating spaces, but they are characterized by having the same width in the horizontal direction.

[0110] As in the insulating window (100) according to the first embodiment of the present invention, the connecting plate (160') and the third insulating member (170') can be joined by pressure rolling, and the third insulating member (170') can be slid and fitted onto the connecting plate (160').

[0111] Below, we examine the performance test results for the thermal insulation window (100) according to the present invention.

[0112] First, we will examine the thermal insulation test results according to the KS F 2278 test method and the airtightness test results according to the KS F 2292 test method.

[0113] The thermal insulation of the thermal insulation window (100) according to the present invention was measured to be 0.685 W / (㎡·K) and the airtightness to be 0.00 m³ / (㎡·h). This can be interpreted as meaning that the thermal insulation and airtightness are excellent when compared to the fact that the thermal insulation of a general aluminum window is 0.9~1.5 m³ / (㎡·h) and the airtightness of a Grade 1 standard is 1.0 m³ / (㎡·h).

[0114] Next, we examine the condensation prevention test results according to the condensation prevention performance test method pursuant to International Transport Ministry Notification No. 2016-835.

[0115] As a result of the test, the condensation prevention performance of the thermal insulation window (100) according to the present invention was measured at 0.17 TDR even at the frame corner, which is the most vulnerable part. This can be seen as a very excellent condensation prevention performance when compared to the standard value of a standard aluminum window frame being around 0.30 TDR.

[0116] As described above, although the present invention has been explained by limited embodiments and drawings, the present invention is not limited to the above embodiments, and various modifications and variations are possible from this description by those skilled in the art.

[0117] Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims set forth below as well as equivalents thereof. Explanation of the symbols
