ABSTRACT:
FIELD OF THE INVENTION AND PRIOR ART
In the following description (in the field of the invention, description of the prior art, problem to be solved by the present invention, description of the invention, and effect of the invention), since the door system is identical to the window system, the description of the invention of the window system will be applied to the description of the door system.
The present invention relates to a hidden rail type window and door system.
A conventional hidden rail type window and door system will be described with reference to the accompany drawings.
FIG. 1
is a front view illustrating a window and door system to which a conventional art is applied, and
FIG. 2
is a sectional view taken along line A—A illustrating a structure of the window and door system.
The conventional window and door system comprises a lower window frame member
1
having rails
12
and a window frame surface member
13
arranged on an inclined line
11
, the rails
12
being hidden by water-proof covers
14
coupled to the surface member
13
and provided with window member guide inlets
19
; and
a lower window member
2
provided with a support member
21
formed on an extending member
23
extended from a lower portion
24
of the lower window member
2
, a roller
22
being disposed between the rail
12
and the support member
21
inside an inlet
19
.
However, in the above described hidden rail type window and door system, although it can prevent water from infiltrating into the interior, since a seal is not provided, thermal efficiency deteriorates. In addition, since water infiltrates into the rail, the roller may be damaged by the water. Since the fixing and supporting structure of the covers
14
is weak, the covers
14
may be deformed, deteriorating the open and close operation of the window member because of the friction between the covers and the extending member
23
of the lower window member
2
or the roller. The roller supporting method for supporting the lower portion of the lower window member
2
cannot effectively support the window member.
PROBLEM TO BE SOLVED BY THE INVENTION
The present invention has been made in an effort to solve the above-described problems. It is an objective of the present invention to provided a window and door system that can prevent water from infiltrating, minimize thermal loss by maintaining a sealing state, and provide a stable open and close operation of the window member by improving the supporting and fixing structure of a cover and a window member.
To achieve the above object, the present invention provides a hidden rail type window and door system comprising:
a lower window (or door) frame having a rail cover attached on a main window (or door) frame, a rail hidden by the rail cover and formed on a concave portion of a window (or door) of the main window (or door) frame of an inside of an inlet, and inlet gaskets mounted on a surface member and the rail cover; and
a lower window (or door) member having a lower portion enhanced by a supporting portion, an extending portion having a roller supporting member on which a roller groove is formed, and a roller device mounted in the roller groove.
