Description

PROFILE FOR WINDOW HAVING PREPREG STIFFENERS
The present invention relates to a profile for a window having stiffeners of a prepreg material, and more particularly, to a profile for a window having stiffeners of a prepreg material inserted into the profile instead of the conventional steel stiffeners.
In general, a profile for a window is made of polyvinyl chloride (PVC) resin due to its heat insulation property, airtightness, watertightness, sound isolation, wind resistance, condensation resistance, flame resistance, and so on.
In this case, the profile using the PVC resin has an advantage in that it can enhance productivity and the degree of freedom in shape at the time of extrusion, but has a disadvantage in that it is very weak in an aspect of strength. Accordingly, in order to enhance strength of the PVC profile, a pipe type iron structure has been conventionally used.
However, because such a profile using the iron structure is weak in heat insulation property, the profile has a serious problem of heat loss of the internal environment, is heavy and is complicated in construction and processing in an aspect of the material.
Moreover, Korean Utility Model Registration No. 423599 discloses a curtain wall having glass plate fixing means using a locking clip, but the curtain wall has a disadvantage in that it is weak in heat insulation property because it is made of a metallic material, such as steel, and is manufactured by extrusion molding.
Accordingly, the present invention has been made in an effort to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a profile for a window having stiffeners of a prepreg material inserted into the profile, thereby reducing weight of window products and increasing heat insulation property.
To achieve the above objects, the present invention provides a profile for a window having a prepreg stiffener including: a body part which is extruded; and stiffeners of a prepreg material which are inserted into an inner space of the body part in the longitudinal direction.
Moreover, the body part is made of a thermoplastic polyvinyl chloride (PVC) material.
Furthermore, the stiffener is attached to the inner circumferential surface of the inner space of the body part by a medium of an adhesive.
Additionally, the stiffener is formed in one of shapes of 'ㄱ', 'ㄷ' and 'ㅁ'.
In addition, the stiffener is formed in a honey comb shape in cross section.
Moreover, the stiffener is formed in a shape of 'I' and is mounted inside the inner space in one direction of the vertical, horizontal and diagonal directions.
Furthermore, the stiffeners are spaced apart from each other at a certain interval inside the inner space.
Additionally, the stiffener is press-fit into a fitting groove formed on the inner circumferential surface in the longitudinal direction.
In addition, the stiffener is a plate that reinforced fiber is impregnated in thermosetting resin and is hardened.
Moreover, the stiffener is formed through the steps of laminating prepreg, heating and pressing the laminated prepreg and hardening thermosetting resin.
Furthermore, the reinforced fiber is carbon fiber.
Additionally, the thermosetting resin is epoxy resin.
As described above, the profile for the window is manufactured in such a way that the stiffener of the prepreg material is inserted into the profile, thereby reducing weight of window products and increasing heat insulation property. Furthermore, the stiffener of the prepreg material and a stiffener of the metallic material can be selectively applied to a double-skin window, so that the profile for the window can enhance heat insulation property and wind pressure resistance.
FIG. 1 is an elevation view of a window to which prepreg stiffeners according to a first preferred embodiment of the present invention are applied.
FIG. 2 is a perspective view of essential parts of the window to which the prepreg stiffeners according to the present invention are applied.

Hereinafter, reference will be now made in detail to the preferred embodiment of the present invention with reference to the attached drawings.
Here, in the drawings, the same components have the same reference numerals even though they are illustrated in different figures.
FIG. 1 is an elevation view of a window to which prepreg stiffeners according to a first preferred embodiment of the present invention are applied, FIG. 2 is a perspective view of essential parts of the window to which the prepreg stiffeners according to the present invention are applied, FIG. 3 is a sectional view taken along the line of I-I of FIG. 1, and FIG. 4 is a sectional view taken along the line of II-II of FIG. 1.
Referring to FIGS. 1 and 2, the profile for the window having the stiffeners according to the preferred embodiment of the present invention includes: a body part 110 which is extruded; and stiffeners 120 of a prepreg material which are inserted into an inner space S of the body part 110 in the longitudinal direction.
That is, the profile according to the present invention has the stiffeners 120 of the prepreg material, instead of the conventional stiffeners of the steel material, inside the inner space S so as to reduce weight of the profile and enhance heat insulation property.
The profile for the window having the stiffeners according to the present invention will be described in more detail.
First, the body part 110 is used to form an outer frame of a window frame 10 or a window leaf 20 and is made of a thermoplastic polyvinyl chloride (PVC) material. In this instance, the extruded body part 110 includes the inner space S having a predetermined cross-sectional form therein to make the stiffeners 120 be inserted into the inner space. The inner space S is divided into an indoor space S1 and an outdoor space S2 in a case of the window frame 10, but there is just one inner space S inside the profile in a case of the window leaf 20.
Referring to FIGS. 3 and 4, the stiffeners 120 are inserted into the inner space S of the body part 110 to enhance durability and heat insulation property of the window. The stiffener 120 of the prepreg material is a plate type product produced through the steps of impregnating carbon fiber having high-strength and high-elasticity or reinforced fiber containing glass fiber, preferably, carbon fiber, in melamine or phenolic resin, preferably, epoxy resin, and hardening the impregnated carbon fiber.
Alternatively, the stiffeners 120 can be formed through the steps of laminating prepreg, heating and pressing the laminated prepreg, and hardening thermosetting resin.
Such stiffeners 120 can previously prevent a defect, such as non-hardening of epoxy resin and are uniform in quality because an amount of the impregnated resin is uniform. Moreover, the stiffeners 120 are easy to be stored and can be used semi-permanently because the stiffeners 120 are not deformed.
Here, preferably, the stiffeners 120 are formed in various shapes to reinforce rigidity of the profile which forms the window. For instance, the stiffeners 120 may be formed in shapes of 'ㄱ', 'ㄷ' and 'ㅁ'. In the present invention, the stiffeners 120 are formed in the shape of 'ㄷ' as an example.
The stiffeners 120 which may be formed in one of the various cross section shapes are attached to the inner circumferential surface of the inner space S or are fixed to the inner circumferential surface of the inner space S by means of a coupling member (not shown) after being press-fit into the inner space S.
In another preferred embodiment, as shown in FIGS. 5 and 6, the stiffeners 120 may be formed in such a way as to be a honey comb structure in cross section in order to reinforce heat insulation and strength at the same time. A honey comb is a honeycombed molded body which is widely used as an insulation material and a lightweight structure material. As described above, the stiffeners 120 of the prepreg material can enhance heat insulation property, maintain the existing strength and realize weight reduction of the window.
In a further preferred embodiment, as shown in FIGS. 7 and 8, the stiffeners 120 may be formed in a shape of I . In detail, the stiffeners 120 may be mounted inside the inner space S in one direction of the vertical, horizontal and diagonal directions. In this instance, the stiffeners having the shape of I may be mounted in such a way as to be spaced at a certain interval inside the inner space S. Additionally, the stiffener 120 may be press-fit into a fitting groove 111 formed on the inner circumferential surface of the inner space S in the longitudinal direction.
Referring to FIG. 3, the stiffeners 120 of the prepreg material formed in one of the various shapes may be respectively inserted and mounted in a plurality of spaces formed inside the window frame 10. That is, in a case of the double-skin window that an indoor window leaf 21 and an outdoor window leaf 23 are joined with each other to be able to slide, the inner space S of the window frame 10 is divided into the indoor space S1 and the outdoor space S2. The stiffeners 120 of the prepreg material are respectively inserted into the profiles of the window frame 10 in order to realize weight reduction of the window frame 10 and enhance durability.
Alternatively, the stiffeners which are respectively inserted into the indoor space S1 and the outdoor space S2 of the window frame 10 may be different in material from each other so as to enhance heat insulation property and wind pressure resistance. In other words, the stiffeners 120 of the prepreg material which have one of the various shapes are inserted into the indoor space S1 of the window frame 10 in order to enhance heat insulation property. Moreover, another stiffener 130 made of steel, stainless steel, aluminum or other material is inserted into the outdoor space S2 in order to reinforce rigidity (See FIG. 6).
In this preferred embodiment, different stiffeners are inserted into the indoor side and the outdoor side of the window frame 10 as an example, but the present invention is not restricted to the above and the stiffeners can be applied to the profiles of the indoor window leaf 21 and the outdoor window leaf 23 as did in the window frame 10. That is, the prepreg stiffeners 120 are inserted into the inner space S of the profile of the indoor window leaf 21 and metallic stiffeners 130 are inserted into the inner space S of the profile of the outdoor window leaf 23 so as to enhance heat insulation property and wind pressure resistance.
As described above, the profile for the window according to the present invention has the stiffeners 120 of the prepreg material integrally inserted into the profile so as to solve the problems of heat insulation property and weight reduction which were demerits of the conventional window having only the steel stiffener.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that the present invention is not restricted to the embodiments and various changes and modifications may be made therein without departing from the technical scope of the present invention as defined by the following claims.
