Function-Improved Gasket for Windoors and Doors}

The present invention relates to a gasket to be mounted on various types of windows, such as sliding windows (column windows), sliding windows, ornari windows, rotary windows, and more particularly, by forming a double-extruded solid silicone rubber and sponge silicone rubber The present invention relates to a gasket for an improved window and door having excellent heat resistance, cold resistance, environmental friendliness, and excellent assembly workability, adhesion and durability.

A window is a generic term for windows for the purpose of daylight and ventilation, and doors for entry and exit of people or objects. The windows and doors must not only function to prevent rain, but also to satisfy the functionalities of the building's insulation, soundproofing, wind pressure, air tightness, watertightness, etc., and also greatly affect the aesthetics of the building's exterior. An important accessory in achieving these functions of the window is the gasket. Gaskets are divided into glazing gaskets, hermetic gaskets, joint gaskets and structural gaskets depending on the application. Depending on the material, there are synthetic resins such as vinyl chloride and thermoplastic elastomer (TPE), and chloroprene and EPDM which are synthetic rubbers. Divided into silicone and silicone. EPG (Ethylene Propylene Diene Monomer rubber) and TPE are mainly used for the gasket.

Republic of Korea Patent Publication No. 2009-0035288 (published on April 09, 2009) discloses a window gasket configured to implement a variety of colors, excellent weather resistance, cold resistance, and is compressed by an external force to facilitate the installation of other members. . More specifically, the gasket 40 of this patent application is formed between the front portion (outside) and the window glass 30 of the window frame 20 installed on the window frame frame 10, as shown in FIG. It is installed in the space to prevent foreign matters such as rain water from flowing into the window frame 20. The gasket 40 has a predetermined length substantially equal to the width of the window glass 30. Referring to FIG. 2, the gasket 40 is positioned in a space between the one surface of the window frame 20 and the window glass 30 so as to have a window frame ( 20 and the first wing part 41 and the second wing part 42 which are in contact with the window glass 30, respectively, and the sealing part 43 formed on the first wing part 41 and the second wing part 42. do. The sealing part 43 is positioned between the upper end of the window frame 20 and the upper end of the window glass 30, and the upper surface is exposed to the outside so that rainwater, etc., is a space between the window frame 20 and the window glass 30. Block incoming Inside the sealing part 43, the space part 44 is formed over the whole length. The space 44 induces deformation of the gasket 40 when the glazing bead is mounted to enable smooth mounting of the glazing bead. That is, when the glazing bead 50 is mounted, the window glass 30 is pushed toward the gasket 40, and at this time, the gasket 40 corresponding to the window frame 30 and the window glass 30 is sealed. Compression force acts on the part 43. The compressive force reduces the thickness of the seal 40 without moving by the space 44 formed therein, so that the glazing bead 50 can be easily mounted. On the other hand, the window gasket 40 includes, as its material, a silicone-based resin, preferably inorganic fillers such as polymethylsiloxane and silica, pigments exhibiting various colors and may include titanium oxide to improve weather resistance.

According to the inventor's review, the window gasket 40 has the advantage of facilitating the mounting of the glazing bead 50 by the space portion 44, on the other hand, the space portion 44 by long-term use Deformation and distortion of the to occur and thus not only the sealing performance is lowered but also has a problem that it does not fully exhibit the buffering capacity against strong external shocks such as typhoons and earthquakes.

On the other hand, Korean Utility Model Publication No. 2009-0010115 (released on October 07, 2009) discloses a gasket for windows and doors. The gasket of the present application is a gasket made of rubber material which is fixedly fitted to a long groove formed on the window frame and the inner circumferential surface of the window frame, and is different from the gasket installed in the space between the window frame (outside) and the window glass mentioned above. More specifically, as shown in FIG. 3, the application includes a window frame 100A and a window frame 100B provided with indoor and outdoor double windows 200A and 200B, wherein the window frame 100A and the window frame ( It relates to a gasket 120 is inserted and fixed to the fixing groove 110 in each of the inner and outer sides that the 100B) abut. As shown in FIG. 4, the gasket 10 of the present application includes a support 11 having an upward length toward the center of the upper surface of the fixture 11, which is interpolated and mounted in a fixing groove of the window frame 100B. 12) and an elliptical buffer portion 13 which is located on top of the support 12 and is double extruded. The buffer part 13 has a hollow part H inside. At this time, the fixing body 11 and the support 12 are made of hard rubber, and the buffer part 13 is made of foam rubber having a high elastic force. The rubber material is EPDM rubber (Ethylene Propylene Diene Monomer rubber). This application suggests that it is desirable to form a coating layer on the buffer 13 to prevent the buffer 13 from wearing out due to repeated friction.

Since the gasket is a gasket fixed by being inserted into a long groove formed on the window frame and the inner circumferential surface of the window frame, the gasket cannot be used as a gasket installed in the space between the window frame (outside) and the window glass.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems of the prior art. Accordingly, it is an object of the present invention to provide an improved window and door gasket having not only excellent heat resistance, cold resistance and environmental friendliness, but also excellent assembly workability, adhesion and durability.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

Figure 5 is a side cross-sectional view of the gasket for windows and doors in accordance with the present invention, Figure 6 is a side cross-sectional view of the window gasket is mounted according to the present invention.

As shown in the figure, the window gasket 1 of the improved function of the present invention has a fixing portion 10 fixed to the window frame 50 and the sealing function portion 20 in close contact with the window glass 30. . The sealing function 20 is in close contact with the upper locking jaw 51 'of the window frame 50 and is also in close contact with the window glass 30. Fixing portion 10 is formed of a non-expanded solid silicone rubber, the sealing function 20 is formed of a foamed sponge silicone rubber. At this time, the solid silicone rubber refers to the conventional silicone rubber is not foamed, sponge silicone rubber refers to the foamed material of the silicone rubber is produced in a sponge shape. Solid silicone rubber and sponge silicone rubber have different physical properties such as hardness and elasticity of materials depending on the presence or absence of foaming.

Silicone material is a material that has excellent resilience, heat resistance, and cold resistance compared to conventional rubber materials such as EPDM and TPE (Thermal Plastic Elastomer), and is also non-toxic and is an environmentally friendly material that is widely used for medical purposes. In addition, since the specific gravity is low, the material can realize a weight reduction of about 15 to 20% compared to the existing rubber material. In addition, since the silicon material is excellent in heat resistance and cold resistance in the cold or cold weather (commercial temperature: -75 ℃ ~ 200 ℃), it can be applied to improve the function of the gasket.

In high-rise buildings, strong winds and heavy rains cause the window glass to push back. At this time, the gasket using the existing solid single material needs time to fill the space formed by the window glass is pushed back. Rainwater or wind can enter through the space before it is filled with existing rubber material.

The window gasket 1 of the present invention is formed by double extrusion using solid silicone rubber as a material for the fixing part 10 and sponge silicone rubber as a material for the sealing function part 20. The window gasket 1 of the present invention having such a structure improves airtightness and watertightness because the soft sponge quickly fills the space formed by the window glass being pushed backward.

The sealing function portion 20 has micropores formed by the foaming of silicone rubber, but does not have a space portion that is distinct from these micropores. It is preferable that the cross section of the sealing function portion 20 has a flat shape at the portion in close contact with the window glass 30 and has a generally round shape at the other portions.

Since the sealing function 20 is formed in a sponge shape by foaming silicone rubber, the sealing function 20 induces deformation of the gasket 40 when the glazing bead is mounted, thereby enabling smooth mounting of the glazing bead. That is, when the glazing bead 60 is mounted, the window glass 30 is pushed toward the gasket 40, and at this time, the gasket 40 corresponding to the window frame 50 and the window glass 30 is sealed. Compression force acts on the functional unit 20. Even if such a compressive force is applied, the sealing function 20 reduces its thickness without being pushed back by the sponge shape and high elasticity to buffer the compressive force acting on the window frame 50, and thus the glazing bead 50 To be easily mounted.

On the other hand, in addition to such ease of mounting, since the sealing function portion 20 has no space portion except micropores therein, even if the gasket 40 is used for a long time to the window frame 50 and the window glass 30 It does not cause deformation and distortion of the sealing function portion 20 of the gasket 40 to be in close contact, thus keeping the sealing property for a long time. In addition, since the sealing function 20 supports them with a high elastic force between the window frame 50 and the window glass 30, and further divides the space necessary for buffering into fine pores, thereby further doubles the buffering force of the sealing function. Sufficient cushioning can be achieved against strong external shocks such as typhoons and earthquakes.

The fixing part 10 includes the locking jaws 51 and 51 of the window frame 50 inside the gasket receiving part 52 such that the window gasket 40 is accommodated in the gasket receiving part 52 formed in the window frame 50. ') Includes a pair of engaging projections 11 and 11'. Thus, a part of the fixing part 10 is accommodated in the gasket accommodating part 52, and the gasket 40 is fixed by the pair of engaging protrusions 11 and 11 ′.

In addition, the fixing part 10 has one external locking protrusion 13 that is caught by the lower locking jaw 51 of the window frame 50 outside the gasket receiving portion 52. Therefore, the gasket 40 is more strongly coupled to the window frame 50, particularly the lower locking jaw 51 by the external locking projections 13. Separately, since the sealing function 20 is in close contact with the upper locking jaw 51 'of the window frame 50, the gasket 40 is also secured to the window frame 50 by the sealing function 20, in particular the upper locking. It is more strongly coupled to the jaw 51 '.

In addition, the fixing part 10 is a hollow part 12 in the body of the fixing part 10 in the area formed by the boundary between the pair of locking protrusions 11 and 11 ′, the external locking protrusion 13, and the sealing function part 20. ) This hollow portion 12 facilitates fitting and removing the fixed portion 10 body to the window frame 50.

The fixing part 10 includes a wing part 14 extending downwardly from the fixing part 10 main body. In addition, the sealing function 20 is formed extending in an oblique upward direction from the body of the fixing part 10. Thus, the sealing function 20 is formed extending in a direction substantially perpendicular to the wing 14. At the end of the wing portion 14 of the fixing portion 10, a projection 14 'extending substantially horizontally with the direction in which the sealing function portion 20 extends is provided. The wing 14 and the projection 14 ′ have a function of balancing the body of the fixed part 10 with respect to the sealing function 20, and also under the sealing function 20, the window glass 30. It can also be a supporting role. The direction here is as follows. The direction of the fixed part 10 main body is defined in the direction of a line perpendicular to a straight line connecting the pair of engaging projections 11 and 11 ', and the direction of the sealed function part 20 is the sealed function part 20 and the fixed part. In the midpoint of the boundary of (10), it is defined as the direction of the line perpendicular to the boundary, and the directions of the wing portions 14 and the projections 14 'are respectively defined as the direction in which they extend. The vertical and horizontal directions referred to herein are not strictly defined mathematically, but approximately vertical and horizontal degrees are sufficient for the naked eye.

In the above description of the window gasket of the present invention through the side cross-sectional view, it can be easily understood that such a gasket extends in the longitudinal direction of the cross section, the perspective view of the window gasket and the window mounted with the gasket The illustration and description thereof are omitted.
