MODES OF THE INVENTION

[0026] Hereinafter, embodiments that are easily performed by those skilled in the art will be described in detail with reference to the accompanying drawings. However, the embodiments of the present invention may be achieved in several different forms and are not limited to the embodiments described herein.

[0027] As described above, in the sliding window improved to increase the openness of the windows, the present invention provides a new thermal insulation structure in a side section in which a door frame and a two-side supporting frame window chassis having a relatively narrow frame width compared to a four-side supporting window chassis are overlapping on each other. According to a preferred embodiment of the present invention illustrated through the drawings shown in the accompanying drawings FIGS. 6a to 6d, when a sliding window 20 is closed in a two-side supporting frame window type sliding window system that supports only both sides of the glass window constituting the sliding window, a side chassis part 21 of the two-side supporting frame window chassis and the door frame 100 in an insulating structure in the side section are overlapping on each other,

[0028] wherein the insulating structure, as shown in FIGS. 6a and 6b, provide a supporting structure in which a roller 20r is directly coupled to a lower glass supporting insulation bracket 20b made of a flexible material without an aluminum chassis under the glass panel 20g so that the roller 20r slides along a guide rail on the door frame 100, and

[0029] wherein the insulating structure provide a foamed insert member for blocking thermal bridge 150 in an insertion pocket 100v of the door frame 100 into which the side cap 21a made of aluminum of the side chassis portion 21 of the sliding window 20 is inserted when a sliding window 20 comprising a glass support insulation bracket 20b attached to the side of the glass panel 20g; and a side chassis portion 21 having a side cap 21a made of an aluminum material provided to support the glass support insulation bracket 20b from the inner and outer surfaces, is sliding and is closing into a door frame 100 (see FIG. 6c),

[0030] wherein the foamed insert member for blocking thermal bridge 150 is fixedly installed in a longitudinal direction on an inner part 110 of the door frame 100 with filling a gap space between the inner part 110 of the door frame 100 and the side cap 21a made of an aluminum material of the side chassis portion 21 of the sliding window 20, and

[0031] wherein a rubber gasket 154 is additionally installed in a longitudinal direction on an outer surface of the foamed insert member for blocking thermal bridge 150 in order to provide airtightness between the side caps 21a made of aluminum and the foamed insert member for blocking thermal bridge 150.

[0032] Here, it is preferable for the foamed insert member for blocking thermal bridge 150 to be formed to have ‘⊂’ shape (a channel shape with one inner side open) that can fill all of a front surface, a side surface, and a back surface of the insertion pocket 100v of the door frame 100.

[0033] In addition, as shown enlarged as [Part-C1] in FIG. 6d, the foamed insert member for blocking thermal bridge 150 according to the first embodiment of the present invention is made of a composite material. That is, an assembly of the composite material provided by attaching foam rubber 156 or foamed Styrofoam™ (foamed styrene resin, expanded polystyrene), which has excellent thermal insulation properties but relatively low ability to maintain shape and durability, to a thin synthetic resin plate 152 having relatively low thermal insulation performance but high ability to maintain shape and durability (as illustrated in FIG. 6d) is installed in the insertion pocket 100v of the door frame 100 in the shape of the ‘⊂’ shape (the channel shape with one inner side open) and on an outer surface of the insertion pocket 100v of the thin synthetic resin plate 152, that is, toward an inner side 110 of the door frame 100, as a square-shaped foam material, foam rubber 156, or foamed Styrofoam™ (foamed styrene resin, expanded polystyrene) is inserted.

[0034] On the other hand, according to the second embodiment of the present invention additionally shown in FIG. 7, the foamed insert member for blocking thermal bridge 150 may be formed by integrally molding a foamed plastic-based heat insulating material 158 that can have both appropriate heat insulation properties and shape retention properties (ability to maintain shape).

[0035] Preferably, fitting protrusions 110a and 152a or fitting grooves for mutual fitting coupling are provided between the foamed insert member for blocking thermal bridge 150 and the inner side 110 of the door frame 100.

[0036] And, the foam rubber 156 (foam rubber) insulator having a closed-cell structure enlarged as [Part-C1] in FIG. 6d has excellent moisture-proofing properties, so even time elapses after construction, thermal conductivity maintains lower than that of other insulators and relatively stable status, therefore it has the advantage of long-lasting insulation retention.

[0037] In addition, the foamed plastic-based heat insulating material 158 shown in FIG. 7 may be a thermal insulation material made by foaming a plastic resin with a foaming agent, and has a lower thermal insulation property compared to a foam rubber 156, but is useful as a building material requiring weather resistance since it can be maintained as a single shape. Representative examples for the foamed plastic-based heat insulating material 158 include extruded expanded polystyrene, rigid urethane foam, polyethylene foam, expanded PVC, and expanded polyurethane, etc. The thermal conductivity may be in the range of about 0.020 to 0.1 kcal/mh° C. at an average temperature of 20° C.

[0038] A numerical analysis model (outside temperature −18° C., room temperature 21° C.: temperature difference ΔT=39° C.) is designed to simulate the temperature of the window system configuration according to the embodiment of the present invention configured as above (that state in which the insertion pocket 110v is filled with the foamed insert member for blocking thermal bridge 150). As a result of the numerical analysis test, as shown in the accompanying drawings FIGS. 8a and 8h, it is possible to maintain a high temperature of 13.1° C. at the reference point of the inner part 110 of the door frame 100, thereby exhibiting high energy efficiency. Furthermore, the effect of preventing dew condensation was achieved.

[0039] And, s shown in the accompanying drawing FIG. 9a, in another comparative example (the comparative state in which the insertion pocket 110v is filled with only air without foamed insert member for blocking thermal bridge), surface temperature of 10.6° C. appears at the reference point of the inner side 110 of the frame 100. As a result, with being compared with the embodiment of the present invention, it was found that a temperature drop of 2.5° C. appeared.

[0040] In the above, while describing in detail a preferred embodiment of the present invention is applied to window having a pair of glass in which a plurality of glass panels 20g are formed by overlapping each other by bonding with a predetermined interval and a sealing member there between to realize a vacuum in the gap. However, it should be understood that the terms of glass panels are not to be constructed as limiting the scope of the present invention, and various modifications and improvements by those skilled in the art using the basic concept of the present invention defined in the following claims are also within the scope of the present invention.
