Best Mode for Carrying out the Invention

[20] Hereinafter, a window system for a multistoried building according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[21] Fig. 1 is a front view of a sliding window system for a multistoried building according to an embodiment of the present invention. The window system according to the embodiment of the present invention comprises a curtain wall 1 fixed to a wall of a building to function as a window frame, and a plurality of fixed windows 30 and sliding windows 10 mounted to the curtain wall 1.

[22] The curtain wall 1 comprises a plurality of vertical mullions Ml, M2 and M3 fixed to a building, and upper, middle and lower transoms Tl, T2 and T3, which are horizontally disposed between the mullions Ml, M2 and M3. The mullions Ml, M2 and M3 and the transoms Tl, T2 and T3 allow the curtain wall 1 to be divided into a plurality of upper and lower spaces Sl and S3. The fixed windows 30 and the sliding windows 10 are mounted to the mullions Ml, M2 and M3 and the transoms Tl, T2 and T3, each of which forming a single space.

[23] In this embodiment, as shown in Fig. 1, the sliding windows 10 are respectively mounted in two upper spaces Sl of the curtain wall 1, and the fixed windows 30 are respectively mounted in two lower spaces S3.

[24] The sliding window 10 mounted in each upper space Sl comprises a sliding window frame 100 movable along rails on the upper and middle transoms Tl and T2, and a fixed window frame 200 fixed to the transoms Tl and T2 and the mullion M2.

[25] The sliding window frame 100 is movable toward the fixed window frame 200 (in the arrow direction of Fig. 1), and so when the sliding window 10 is opened, the sliding window frame 100 overlaps with the fixed window frame 200. [26] Also, the fixed window 30 mounted in the lower space S3 comprises a plurality of fixed window frames 300 laterally disposed while being fixed to the middle and lower transoms T2 and T3 and the mullions Ml, Ml 1, M2, M21 and M3.

[27] Here, it will be apparent that window glasses are fixed to the sliding and fixed window frames of the sliding window and the fixed window frames of the fixed window.

[28] Meanwhile, it will be apparent that, contrary to the configuration shown in Fig. 1, fixed windows may be mounted in two upper spaces of the curtain wall and sliding windows may be mounted in two lower spaces.

[29] Hereinafter, the sliding window 10 and the fixed window 30 shown in the left side of

Fig. 1 will be described with reference to Figs. 1, 2 and 3.

[30] Sliding Window QO)

[31] The sliding window 10 mounted to the upper space Sl of the curtain wall 1 comprises the slidable sliding window frame 100 and the fixed window frame 200.

[32] Fig. 2 is a sectional view taken along the line A-A of Fig. 1, and Fig. 3 is a sectional view taken along the line B-B of Fig. 1. Figs. 2 and 3 illustrate the sliding window frame 100 constituting the sliding window 10.

[33] Meanwhile, reference symbols "Tl" and "T2" of Figs. 2 and 3 respectively designate the upper and middle transoms fixed to a side defining an open portion of a building wall, and "Ml" designates the mullion.

[34] The sliding window frame 100 comprises upper and lower horizontal frames 111 and

112 corresponding to the upper and middle transoms Tl and T2 and two vertical frames 121 and 122 fixed to both ends of the horizontal frames 111 and 112, respectively. Window glasses W are respectively fixed to the upper and lower horizontal frames 111 and 112 and the two vertical frames 121 and 122.

[35] Rails 21 and 22 for guiding the sliding movement of the upper and lower horizontal frames 111 and 112 are respectively installed on the surfaces of the upper and middle transoms Tl and T2, and guide bars 113 and 114 corresponding to the rails 21 and 22 are respectively fixed to an upper end of the upper horizontal frame 111 and a lower end of the lower horizontal frame 112 of the sliding window frame 100.

[36] Thus, the sliding window frame 100 may be slid along the rails 21 and 22 of the upper and middle transoms Tl and T2.

[37] Meanwhile, sealing elements 115 and 116 are respectively mounted in an upper surface of the upper horizontal frame 111 of the sliding window frame 100 and a lower surface of the lower horizontal frame 112 through their entire lengths, and these sealing elements 115 and 116 are vertically moved by the operation of a handle H installed on the indoor side surface of any one vertical frame 121.

[38] For example, if the handle H is rotated in the clockwise direction about its axis, the sealing element 115 mounted in the upper surface of the upper horizontal frame 111 is moved upward as shown in Fig. 3 (which is indicated by a thin solid line 115-1), and at the same time, the sealing element 116 mounted in the lower surface of the lower horizontal frame 112 is moved downward (which is indicated by a thin solid line 116-1). The sealing elements 115 and 116 moved as mentioned above are respectively brought into close contact with the rails 21 and 22 installed to the upper and middle transoms Tl and T2. As a result, the indoor space is perfectly isolated from the outdoor space by the sealing elements 115 and 116.

[39] On the contrary, if the handle H is rotated in the counterclockwise direction about its axis, the sealing element 115 mounted in the upper surface of the upper horizontal frame 111 is moved downward, and the sealing element 116 mounted in the lower surface of the lower horizontal frame 112 is moved upward, as indicated by thick solid lines in Fig. 3. Thus, the sealing elements 115 and 116 do not give any influence on the sliding movement of the sliding window frame 100.

[40] The mechanism for moving the sealing elements 115 and 116 by the manipulation of the handle H is disclosed in Korean Laid-open Patent Publication No. 2005-0054455, and thus, its configuration and function are not described in detail.

[41] Meanwhile, Figs. 1 and 2 show a portion of the fixed window frame 200 constituting the sliding window 10.

[42] The fixed window frame 200, which is another component of the sliding window 10, is installed in the upper space S 1 of the curtain wall 1 together with the sliding window frame 100. The fixed window frame 200 comprises upper and lower horizontal frames 211 and 212 respectively fixed to the upper and middle transoms Tl and T2 and two vertical frames 221 and 222 respectively fixed to both ends of each horizontal frame 211 or 212 (here, only the vertical frame 222 is shown in Fig. 1, and only the vertical frame 221 is shown in Fig. 2). Among two vertical frames, the vertical frame 222 is fixed to the mullion M2.

[43] Window glasses are respectively fixed to the upper and lower horizontal frames 211 and 212 and the two vertical frames 222 of the fixed window frame 200. Meanwhile, the reference symbol "Bl" in Fig. 2 designates a glazing bead, which is mounted to indoor side borders between the window glass W and each frame 211, 212, 221 or 222 after the window glasses W are mounted to the horizontal frames 211 and 212 and the vertical frames 221 and 222 of the fixed window frame 200. The glazing bead Bl allows the window glass W to be firmly fixed to the fixed window frame 200.

[44] As shown in the right side of Fig. 2, when the sliding window 10 is closed, the vertical frame 221 of the fixed window frame 200 is positioned in the front of the vertical frame 122 (not corresponding to the mullion) of the sliding window frame 100.

[45] Further, in this configuration, when the sliding window frame 100 is moved and then becomes a complete open state, the sliding window frame 100 and the fixed window frame 200 are overlapped with each other.

[46] As shown in Fig. 2, if the external wind pressure is applied to the sliding window frame 100 (in an arrow direction) in a state where the sliding window 10 is closed, the sliding window frame 100 is shaken. Thus, in the sliding window system according to the present invention, a locking means is installed to the vertical frame 122 of the sliding window frame 100 and the vertical frame 221 of the fixed window frame 200, which correspond to each other in a closed state, for preventing the sliding window frame 100 from being shaken by the external wind pressure.

[47] Fig. 4 is a perspective view of an "a" portion of Fig. 2, showing first and second locking members constituting the locking means provided for preventing a shaking of the sliding window frame.

[48] The second locking member installed to a rear surface of the vertical frame 221 of the fixed window frame 200 is a base 290 with a predetermined area, and an arc- shaped cut portion 291 with an opened outer end is formed on one side of the base 290. A groove 292 with predetermined height and depth is formed on the surface of the cut portion 291 over the entire length of the cut portion 291.

[49] Meanwhile, the first locking member installed to a front surface of the vertical frame

122 of the sliding window frame 100 comprises a base 190 fixed to the vertical frame 122, and a cylindrical stopper 191 fixed to the base 190 and having a predetermined height. An extension piece 192 extended in parallel with the base 190 is formed on an upper end of the stopper 191. A thickness of the extension piece 192 is identical to or slightly smaller than the height of the groove 292 formed in the cut portion 291 of the base 290 that is the second locking member of the fixed window frame 200.

[50] When the sliding window frame 100, which is in the open state, is slid in a direction opposite to the arrow direction of Fig. 1 and then becomes the closed state (i.e., a state shown in Figs. 1 and 2), the base 190 fixed to the sliding window frame 100 and the base 290 fixed to the fixed window frame 200 are overlapped with each other as shown in Fig. 2.

[51] In this process, the stopper 191 fixed to the base 190 of the sliding window frame

100 is positioned within the cut portion 291 formed in the base 290 of the fixed window frame 200, and particularly, the extension piece 192 at the upper end of the stopper 191 is received in the groove 292 formed on the side surface of the cut portion 291.

[52] In this state, the sliding window frame 100 is supported to the fixed window frame

200 firmly fixed to the mullion M2 and the transoms Tl and T2 of the curtain wall 1 through the shaking preventing means. Thus, in a state where the sliding window frame 100 is closed, the sliding window frame 100 is not shaken even though great external wind pressure is applied thereto.

[53] Meanwhile, as shown in Fig. 2, metallic reinforcing members 281 and 282 are mounted within each of the vertical frames 221 and 222 and the horizontal frames 211 and 212 of the fixed window frame 200 in order to prevent deformation of each frame. These reinforcing members 281 and 282 are fixed to each frame by a fixing means such as bolts and preferably arranged in a direction parallel with an external wind pressure direction.

[54] In addition, finishing materials 191 and 192 may be respectively fixed to indoor side surfaces of the upper and lower transoms Tl and T2 on which the sliding window frame 100 is slid.

[55] As shown in Fig. 3, borders between the upper transom Tl and the upper horizontal frame 111 of the sliding window frame 110 and between the middle transom T2 and the lower horizontal frame 112 are exposed to the outside. In particular, the rails 21 and 22 respectively mounted to the transoms Tl and T2 and the guide bars 113 and 114 respectively mounted to the horizontal frames 111 and 112 and corresponding to the rails 21 and 22 are exposed to the outside.

[56] In this embodiment, finishing material is mounted to inner sides of the upper and lower transoms for interior decoration. This finishing material has the length same as those of the upper and lower transoms.

[57] The finishing material 191 mounted to the upper transom Tl has a lower portion corresponding to an upper end of the upper horizontal frame 111, and also the finishing material 192 mounted to the lower transom T2 has an upper portion corresponding to a lower end of the lower horizontal frame 112. Thus, the rails 21 and 22 and the guide bars 113 and 114 are not observed from the indoor side, thereby improving aesthetic conditions for the interior decoration.

[58]

[59] Fixed Window GO)

[60] As shown in Fig. 1, the fixed window 30 is mounted in the lower space S3 of the curtain wall 1 and comprises the plurality of fixed window frames 300. Each fixed window frame 300 has the same configuration and function, and so the fixed window 30 shown in the left side of Fig. 1 will be described as an example below.

[61] Meanwhile, although Fig. 1 illustrates that the additional middle mullions Mi l and

M21 are respectively installed between the mullions Ml and M2 and between the mullions M2 and M3 and the fixed window frames 300 are respectively mounted therebetween, it will be apparent that the fixed window frames 300 may be mounted without any middle mullion.

[62] The fixed window frame 300 constituting the fixed window 30 mounted in the lower space S3 of the curtain wall 1 is fixedly installed to the transoms T2 and T3 and the mullions Ml and Mi l.

[63] Fig. 5 is a sectional view taken along the line C-C of Fig. 1, and Fig. 6 is a sectional view taken along the line D-D of Fig. 1.

[64] The fixed window frame 300 comprises upper and lower horizontal frames 311 and

312 respectively fixed to the middle and lower transoms T2 and T3, and two vertical frames 321 and 322 fixed to the mullions Ml and Mi l. Meanwhile, it will be apparent that the window glass W is fixed to the fixed window frame 300.

[65] The fixed window frame 300 of the fixed window 30 has the structure same as that of the fixed window frame 200 constituting the sliding window 10 (see the right portion of Fig. 2 and the lower portion of Fig. 3). In particular, although Figs. 5 and 6 illustrate for convenience that the vertical and horizontal frames 321, 322, 311 and 312 of the fixed window frame 300 have a box shape, the inner structure of each of the frames of the fixed window frame is the same as that of each of the vertical and horizontal frames 221, 222, 211 and 212 constituting the fixed window frame 200 of the sliding window 10.

[66] That is, each of the vertical and horizontal frames 321, 322, 311 and 312 of the fixed window frame 300 comprises a metallic reinforcing member mounted therein to prevent each frame from being deformed by external wind pressure.

[67] Meanwhile, in Figs. 5 and 6, reference symbol "B2" designates a glazing bead.

Glazing bead B2 for fixing the window glass W are mounted to indoor side borders between each of the vertical frames 321 and 322 of the fixed window frame 300 and each of the mullions Ml and Mi l and between each of the horizontal frames 311 and 312 and each of the transoms T2 and T3. These glazing beads B2 allow the window glass W to be firmly fixed to the fixed window frame 300.

[68] As shown in Figs. 2, 3, 5 and 6, structures for mounting the glazing beads Bl and B2 utilized for fixing the window glasses W are provided in the fixed window frame 200 of the sliding window 10 and the fixed window frame 300 of the fixed window 30 at the indoor side. Thus, in a state where the fixed window frame 200 of the sliding window 10 and the fixed window frame 300 of the fixed window 30 are fixed to the mullions Ml and M2 and the transoms Tl, T2 and T3, a worker can mount the window glasses W in the indoor side.

[69] The aforementioned preferred embodiment of the present invention is disclosed only for illustrative purposes. Accordingly, it will be understood by those skilled in the art that various modifications, changes and additions can be made thereto within the spirit and scope of the invention. The modifications, changes and additions will be considered to fall in the scope of the present invention defined by the appended claims.
