Abstract

The present invention relates to a flat rail fitting device in which changing a structure is easy. A fitting device having a double rail structure can be implemented by a very simple work in which a window frame cover without a rail is coupled to an upper portion of a window frame by being pressed and fitted and a pair of double rollers installed at a plurality of roller supporters are mounted on a rail rock portion of a window frame rail. Also, the fitting device having a double rail structure can be structurally changed to be a fitting device having a single rail structure by a very simple work in which, after separating the roller supporters from the window frame rail by sliding the roller supporters and separating the window frame cover without the rail from the window frame rail, a single rail window frame cover is coupled to the window frame rail by being fitted and coupled and a roller of a single roller supporter is mounted on the rail of the single rail window frame cover. Therefore, by a very simple work in which the window frame cover without the rail and the roller supporters and the single rail window frame cover and the single roller supporter are coupled to and separated from a window frame and a door frame without a separate fastening means, the structure of an already installed fitting device can be changed from a double rail structure to a single rail structure or in the opposite way, such that compatibility and workability are remarkably improved.

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a flat-

[0001] The present invention relates to a flat rail window device that is easy to change in structure, and more particularly, to a flat rail window device that can be easily changed in structure, and more particularly, And more particularly to a flat rail window device which can be easily changed in structure and can be changed from a dual rail structure to an outer rail structure and vice versa.

In recent years, various types of windows have been developed such as a window system with a sliding door system, which is widely applied to comparatively large windows such as a partition window of a living room and a balcony window, and a security window with a security function, Has been used.

The windows used in various buildings are essentially composed of doors, windows, doors and windows, and window frames that are slidably and discretely-coupled. These windows have weather resistance with high resistance against outside air, durability And high mechanical properties to withstand the load of the glass.

In the window frame of the conventional window system, there is formed a rail groove in which a door and a window are slidably opened and closed. The rail groove has a disadvantage that it acts as a risk factor to give a foot or a foot to a foot when a person passes by. In addition, in the case of a window frame applied to a veranda, foreign matter such as dust easily accumulates in the rail groove, and cleaning work for removing foreign substances from the rail groove is difficult. Especially, the window frame applied to the veranda window and the rail groove There is a disadvantage in that the airtightness or drainage property is greatly deteriorated due to the infiltration of foreign wind or rainwater easily.

To solve these drawbacks, there are rails hiding windows which have a structure that does not expose the rail grooves of the window frame and improve the airtightness and drainage. However, since the structure for joining the doors and windows to the rail grooves of the window frame is complicated, There is a problem that it is very difficult to separate the window from the rail groove and there is a disadvantage in that the drainage is not good because the drainage structure of the rainwater is not separately provided and the structure for shielding the draft is simple, There is a drawback that it can not.

Also, it is very difficult to replace such a rail concealed window once it has been constructed like ordinary windows. In order to change the window system of the existing outer rail structure to a dual rail structure or to change the structure of the window system to improve airtightness and watertightness, the window frame frame and the entire window frame had to be replaced.

In the general double window frame structure, the rail grooves are formed in four parts of the window frame 20, but the rail grooves 50 and the U-shaped multiple roller supports 110, Are formed only on both sides of the window frame (20). Accordingly, the appearance of the rail groove is improved in comparison with the conventional structure in which the rail groove is formed in the four portions of the window frame 20, and the windproof property and the heat insulating property are improved.

10, a buried support base 120 is embedded in a side surface of the window frame 20, and a buried lock device 121 is coupled to the buried support base 120. As shown in FIG.

Therefore, unlike the conventional case in which the locking device is protruded to the outside of the window frame 20, since the flushing device 121 is embedded in the window frame 20, safety accidents are prevented, and the beauty of the window device is greatly improved do.

A buffer packing 122 is coupled to the side surface of the window frame 11. The cushioning packing 122 reduces noise and impact when the window frame 11 is closed to the window frame 20, and improves airtightness and heat insulation.

11 and 12 are a side sectional view and a flat sectional view showing another embodiment in which the present invention is applied to a single window structure.

The plural roller support rods 110 shown in Figs. 7 to 10 are provided such that their openings are opposed to each other, while the plural roller rods 110 of Figs. Feature.

In addition, the present invention may be applied to a double-pane structure as shown in FIGS. 7 to 10, but may also be applied to a double-pane structure as shown in FIGS. The remaining configuration, operation, and effect are similar to those of Figs. 7 to 10. Fig.

Figs. 13 to 15 are side cross-sectional views showing another embodiment of the lower rail structure, a cross-sectional side view thereof, and a partial cutaway perspective view thereof.
