BEST MODE

Reference will now be made in greater detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The exemplary embodiments described hereinbelow are provided for fully conveying the scope and spirit of the invention to those skilled in the art, so it should be understood that the embodiments may be changed to a variety of embodiments and the scope and spirit of the invention are not limited to the embodiments described hereinbelow.
FIG. 1 is a sectional view illustrating a sliding window according to the present invention.
As shown in FIG. 1, the sliding window of the present invention includes: a window frame 1 b that is set in a wall and is formed in the shape of a frame; and a sash 1 a installed inside the window frame 1 b and formed in the shape of a frame for holding panes of glass therein.
In a lower part of the sash 1 a, a window wheel unit 2 is installed. The window wheel unit 2 includes: wheels that are in sliding contact with a rail 1c of the window frame 1b so as to realize an easy sliding motion of the sash 1a along the rail 1c; and a window wheel unit 2 that has elements bringing the sash 1a into close contact with the window frame 1 b or releasing the sash 1 a from the window frame 1 b.
The window wheel unit 2 includes: an outer housing 2a, an inner housing 2b, and a wheel housing 2g that are sequentially placed in a direction from the outside to the inside. In an upper part of the window wheel unit 2, a diverting unit 3 is installed. The diverting unit 3 actuates the window wheel unit 2, and diverts the window wheel unit 2 to the left or right.
The diverting unit 3 includes: a connector 31 that extends along a side surface and a lower surface of the sash 1 a from a handle manipulated by a user and transmits power; a cam 32 installed in the window wheel unit 2 and connected to the connector 31; a slot hole formed in each of the outer housing 2a and the inner housing 2b; and a guide hole 2i formed in the wheel housing 2g.
The diverting unit 3 may be configured in a European turn-only style form.
When a user opens or closes the window by manipulating the handle, the wheel housing 2g is moved to the left or right, and brings the sash 1 a into close contact with the window frame 1 b or releases the sash 1a from the window frame 1 b. Here, the material of the diverting unit 3 is not limited, but the diverting unit 3 may be made of a plastic material that can reduce friction between the diverting unit 3 and the cam 32.
FIG. 2 is a plan view of the sash 1 a according to the present invention.
The window wheel unit 2 is mounted to the lower part of the sash 1 a by locking screws 2d tightened to respective locking screw holes. Here, it is possible to adjust the gap between the sash 1a and the window wheel unit 2 by tightening or loosening an adjusting screw 2e, so the sash 1a can be easily set in the window frame 1b.
With reference to FIG. 1, to avoid interference between the locking screws 2d and the diverting unit 3, setting the locking screws 2d with sufficient intervals remaining between the locking screws 2d and the diverting unit 3 is required.
The diverting unit 3 may be installed in a seat groove 10 that is formed in the bottom surface (the lower surface) of the sash 1 a.
FIGS. 3 and 4 are front views illustrating in detail the window wheel unit 2 according to the present invention.
As described above, the window wheel unit 2 includes the outer housing 2a, the inner housing 2b (see FIG. 7), the wheel housing 2g, and the wheels 2c.
The outer housing 2a is the outermost housing of the window wheel unit 2, with the locking screw holes formed in the outer housing 2a. The outer housing 2a is mounted to the lower part of the sash 1 a by the locking screws 2d tightened to respective locking screw holes. Here, the outer housing 2a may be configured with a width of 30mm or greater, for example, a width of 30mm to 50mm.
The inner housing 2b is provided inside the outer housing 2a and is coupled to the outer housing 2a by an adjusting pin 2f. The adjusting screw 2e is connected to an end of the inner housing 2b after passing through the outer housing 2a. When the adjusting screw 2e is rotated to be tightened or loosened, the adjusting pin 2f is moved upward and downward so as to adjust the gap between the sash 1a and the window wheel unit 2. For example, when the adjusting screw 2e is rotated to be moved forward or rearward, the inner housing 2b is moved forward or rearward, and the adjusting pin 2f is moved upward or downward. Due to the upward or downward movement of the adjusting pin 2f, a bracket 4 connected to the adjusting pin 2f is moved upward or downward, so that the sash 1a is moved upward or downward. Thus, in the sliding window of this invention, it is possible to adjust the height of the sash 1 a.
In other words, when rotating the adjusting screw 2e, the inner housing 2b connected to the adjusting screw 2e is biased to be moved forward or rearward inside the outer housing 2a. When the inner housing 2b is biased to be moved forward or rearward by the adjusting screw 2e, the inner housing 2b is stopped by both the outer housing and a locking pin after the inner housing 2b is moved to a predetermined distance. In other words, when the inner housing 2b is biased to be moved further after the bottom surface of the inner housing comes into contact with the locking pin, the bottom surface of the inner housing 2b forcibly moves the locking pin upward and downward, so the sash is moved upward and downward.
Here, each of the slot hole H1 of the outer housing 2a and the slot hole H2 of the inner housing 2b may be configured as a longitudinal hole, as shown in the drawings.
The wheel housing 2g is a housing placed inside the inner housing 2b. The wheel housing 2g is firmly connected to the inner housing 2b by the locking pin 2h provided at at least each side of the wheel housing 2g so that the wheel housing 2g is not movable upward or downward relative to the inner housing 2b. In the wheel housing 2g, at least two wheels 2c are mounted to the bracket 4 made of metal. Here, the wheel housing 2g is configured in such a way that the wheel housing 2g can be stably moved along the adjusting pin 2f to the left or right in a state in which the wheel housing 2g is stably connected to both the inner housing 2b and the outer housing 2a by the adjusting pin 2f passing through the center of the bracket 4. To this end, it is required to define a moving space between the wheel housing 2g and the locking pin 2h.
FIGS. 5a, 5b, and 5c are views illustrating the operation of the diverting unit according to the present invention.
As shown in the drawings, the diverting unit 3 may include: the connector 31 that extends along the side surface and the lower surface of the sash 1 a from the handle manipulated by a user and transmits power; the cam 32 installed in the window wheel unit 2 and connected to the connector 31; the slot hole formed in each of the outer housing 2a and the inner housing 2b; and the guide hole 2i formed in the wheel housing 2g.
In the diverting unit 3, the connector is mounted to a locking slot formed in the sash at a location above the upper part of the window wheel unit, and the cam is commonly combined with slot holes 2aH and 2bH of the outer and inner housings and with the guide hole 2i of the wheel housing.
The upper part of each of the outer housing 2a and the inner housing 2b of the window wheel unit is holed by forming a slot hole having a longitudinal shape in each of the outer housing 2a and the inner housing 2b. Further, the wheel housing 2g is holed by forming the guide hole in the wheel housing 2g, so the cam 32 to which the power generated from the handle manipulated by a user is transmitted is commonly set in the outer housing 2a, the inner housing 2b, and the wheel housing 2g. When the handle is manipulated by the user, the outer housing 2a and the inner housing 2b may be rectilinearly moved to the left or right according to the shapes of the slot holes formed in the upper parts of the outer housing 2a and the inner housing 2b, and the wheel housing 2g set in the inner housing 2b is horizontally moved forward or rearward according to the shape of the guide hole 2i formed in the wheel housing 2g.
In this case, the wheels of the window wheel unit 2 are biased to be horizontally moved forward or rearward. However, in a practical sliding window, the wheels are not moved on the rail, so the sash is horizontally moved forward or rearward while the weight (including the weight of panes of glass) is supported by the locking pin 2h.
Accordingly, when a user manipulates the handle, the wheel housing is moved to the left or right, so the sash is brought into close contact with the window frame or is released from the window frame. Here, when the sliding window is opened, the sash is released from the window frame. However, when the sliding window is closed, the sash is brought into close contact with the window frame.
FIGS. 6 and 7 are a side view and a rear view illustrating a wheel 2c which constitutes the window wheel unit 2 combined with the sash 1 a and which is in contact with a lower rail 1c of the window frame 1b, and a diverting unit 3 set in the upper part of the window wheel unit 2.
FIGS. 8 and 9 illustrate another diverting unit 3 which is set in the upper part of the sash 1 a and which functions to bring the sash 1 a into close contact with the window frame 1 b or to release the sash 1 a from the window frame 1 b. This diverting unit 3 includes: a guide pin 2k that is in contact with the window frame 1 b and is connected to the cam of the diverting unit 3; and a guide housing 2j that is provided between the guide pin 2k and the diverting unit 3.
FIG. 10 is a view illustrating manipulation for the handle.
FIG. 11 is a view illustrating an operation of the window wheel unit 2 actuated by the diverting unit 3 when manipulating the handle. Here, for example, when the window wheel unit 2 is moved from the left to the right, the sash 1 a is brought into close contact with the window frame 1b. On the contrary, when the window wheel unit 2 is moved from the right to the left in response to manipulation for the handle, the sash 1 a is released from the window frame 1 b.
FIGS. 12a and 12b are views illustrating a released state and a close contact state of the sash realized by manipulating the handle as described above with reference to FIGS. 10 and 11. When the window is opened, the sash is released from a gasket G attached to the window frame, a narrow gap is formed between the sash and the window frame, so the sash can slide on the rail. However, when the window is closed, the sash comes into close contact with the gasket G attached to the window frame, the gasket G seals the gap between the sash and the window frame, thereby realizing airtight, watertight, insulating, and soundproof performance.
As described above, the window wheel unit 2 of the present invention realizes a reduction in the number of parts and a simple assembling process. Further, due to the window wheel unit 2, it is possible to remove a gap between the sash 1 a and the window frame 1 b, so the present invention can realize improved airtight, watertight, insulating, and soundproof performance and can improve wind pressure resistance performance. Further, in the present invention, the window wheel unit 2 actuated by the diverting unit 3 may be installed in each of the upper and lower parts of the sash 1 a, so the present invention remarkably improve crime prevention performance due to a locking function of the guide housing 2j. In the present invention, the close contact state, locked state, and released state of the sash relative to the window frame may be sequentially realized by manipulating the handle.
FIG. 13 illustrates another embodiment of the present invention. As shown in FIG. 13, to improve the operational efficiency of the sliding window of the present invention, a wheel guide 20 may be provided in each window wheel unit 2.
In this embodiment, the wheel guide 20 is provided at each side of the wheel 2c of the window wheel unit 2 by protruding downward in parallel with the wheel 2c. When the sash 1 a is brought into close contact with the window frame 1 b or is released from the window frame 1b by the operation of the window wheel unit 2, the wheel guide 20 can efficiently disperse the weight of the window wheel unit 2 to the left and right, so the window wheel unit 2 can be efficiently operated in a stably supported state.
