TECHNICAL FIELD

The present invention relates to a modular edge connection fitting which is used for a modular window frame and window pair and a window structure using the same, and more particularly to, a curved brace edge connection fitting and a curved brace window sash edge connection fitting corresponding to the curved brace edge connection fitting and a window structure using the same, to thereby enhance a coupling intensity of existing modular edge connection fittings to simultaneously enhance air-tightness and heat insulation and to thus provide effects of curved design and easy cleaning.

BACKGROUND ART

An existing window frame edge connection fitting which is widely used is shown inFIG. 1.

FIG. 1shows part of an edge portion at one side of a window frame. For convenience of understanding, a horizontal bar2and a vertical bar3which are somewhat complicated are simply represented in sectional shape. Protrusions10are inserted into the horizontal bar2and the vertical bar3, respectively, in order to firmly couple an edge connection fitting with the horizontal bar2and the vertical bar3, when the edge connection fitting is fitted with the horizontal bar2and the vertical bar3. A rubber packing12is interposed between each of the horizontal bar2and the vertical bar3and the edge connection fitting5, in order to enhance air-tightness, respectively. On the upper portion of the horizontal bar2are formed a raised step6, a groove13and a packing insertion groove (not shown) in lengthy direction. Likewise, on the upper portion of the vertical bar3are formed a raised step6, a groove13and a packing insertion groove (not shown) in lengthy direction. In assembly, a worker fits the cut end portions of the horizontal bar2and the vertical bar3with the edge connection fitting5and then makes holes such as piece holes or screw holes into the edge connection fitting5by using a drilling machine, to then tighten pieces or screws8into the piece holes or screw holes. InFIG. 1, a reference numeral7denotes a piece hole or screw hole.

FIG. 2shows a coupled state ofFIG. 1, in which the horizontal bar2and the vertical bar3are coupled with the edge connection fitting5according to the conventional art. A window frame is classified into a convex type and a concave type according to the shape of the window frame with which a window sash is fitted.FIG. 2shows a convex type window frame. A window sash is slid on the raised step6. A concave type window frame is fabricated in the same shape and fabrication method as that of the convex type window frame, although it is not shown in the drawings.FIG. 2shows positions of the raised step6, the groove13, and the screw hole7.

FIG. 3is a perspective view showing a coupling relationship of a conventional window sash edge connection fitting5a. A glass groove17ais formed in the inner circumference of the window sash edge connection fitting5a, and a packing insertion groove11ais formed in the lower portion of the glass groove17a. The window sash edge connection fitting5ais coupled in the same pattern as that of the window frame edge connection fitting5. That is, protrusion10aof the window sash edge connection fitting5aare fitted into a horizontal bar2aand a vertical bar3a, respectively, and tightened by screws8ato then be assembled with the horizontal bar2aand the vertical bar3a.

InFIGS. 2 and 3, the window frame edge connection fitting5and the window sash edge connection fitting5aprovide a coupling function which fits horizontal bars2and2aand vertical bars3and3a, respectively. Since the edge connection fittings5and5awhere the horizontal bars2and2aand vertical bars3and3aare crossed are coupled perpendicularly, the coupled modular window frame is weak with respect to a diagonally lateral compression force. Thus, in the case of windows at the windy seaside areas, high buildings, or seismal places, stronger connection fittings are required.

Also, the window frame edge connection fitting5and the window sash edge connection fitting5ahave no proper structures of packing insertion grooves11aofFIGS. 2 and 3into which packing members such as mohair called wind-proof hair (not shown) and gaskets made of soft rubber can be inserted.

That is, the horizontal bars2and2aand vertical bars3and3aare crossed are coupled perpendicularly, at the edge connection fittings5and5a. Accordingly, packing members cannot be inserted into packing insertion grooves. Thus, the packing members are cut and used according to the lengths of the horizontal bars2and2a, respectively. In the case of the vertical bars3and3a, the packing members are also cut and used according to the lengths thereof. The packing members such as mohair called wind-proof hair (not shown) and gaskets made of soft rubber which are inserted into the horizontal bars2and2aand vertical bars3and3aare cut and used in proper lengths according to a skillfulness of a worker who performs a window assembly, and are fitted into the packing insertion grooves11a. No matter how a worker is skill, he or she cuts packing members such as mohair called wind-proof hair (not shown) and gaskets made of soft rubber by eye measure in order to heighten a working speed, when the packing members are fitted into the packing insertion grooves11aformed in the horizontal bars2and2aand vertical bars3and3a. As a result, the packing members may be cut shortly in comparison with the lengths of the horizontal bars2and2aand vertical bars3and3a, and thus it is difficult to insert the packing members such as mohair called wind-proof hair (not shown) and gaskets made of soft rubber which have been cut in proper lengths into the packing insertion grooves11aformed in the horizontal bars2and2aand vertical bars3and3a. The packing members having been inserted into the packing insertion grooves formed in the horizontal bars2and2aand vertical bars3and3areduce heat insulation and air-tightness, to thereby lower an energy efficiency and generate noise. Also, it is not so easy to clean dust collected in the perpendicular edges.

FIG. 13is a perspective view of a typical casement which is one of casements.FIG. 14is a perspective view of a tilt which is one of casements.FIG. 15is a lateral cross-sectional view of a project which is one of casements. An edge connection fitting for a modular casement is not much developed in comparison with that of a slider. However, in the case of a slider which is opened in the form of protruding inwards or outwards in view of structure of a window, edge portions of a window sash1ahave a sharp point, respectively. This, if an article or person collides with the pointed edges due to carelessness, the article may be broken or the head or face of the person may be damaged severely. The protruded edge portions of synthetic resin window, wooden window, and hybrid window are always dangerous. In particular, since the edge portions of an aluminum window are sharp like a knife blade, an article or the head or face of person colliding with the pointed edges due to carelessness may be broken or damaged severely. Such an accident frequently takes place.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinbelow, a curved brace edge connection fitting and a window structure using the same according to the present invention will be described with reference to the accompanying drawings.

FIG. 4is a perspective view showing a coupling relationship of a curved brace window frame edge connection fitting which is used for a slider according to an embodiment of the present invention.FIG. 5is a laterally cross-sectional view showing a curved brace window frame edge connection fitting which is used for a slider according to an embodiment of the present invention.

Referring toFIGS. 4 and 5, a brace116which does not exist in the conventional window frame edge connection fitting5ofFIG. 1is formed in a curved brace window frame edge connection fitting105. The brace116plays a role of preventing distortion and contortion of the window frame so that the frame is not deformed due to a compression force or tension applied to the window frame structure, and uniformly dispersing wind, pressure and vibration applied to the window frame structure to a horizontal bar102and a vertical bar103, as well.

A portion playing a role of the brace116can be formed as a linear portion of a triangle. However, the brace116can be preferably curved as shown inFIG. 5. If the brace116is curved, additional effects such as a design effect of esthetic appreciation, an easy cleaning, and safety due to a curved surface can be obtained.

The inner circumference of the curved brace window frame edge connection fitting105has a structure that a raised step106, a groove (not shown), and a packing insertion groove111having the same shapes as those of the raised step106, the groove (not shown), and the packing insertion groove111formed in each of the horizontal bar102and the vertical bar103are curved. The edge portion in the conventional art is formed perpendicularly, to thus cause a difficult cleaning. However, since the inner circumference of the curved brace window frame structure edge connection fitting105is curved, an effect of an easy cleaning can be obtained. Also, a packing member (not shown) such as mohair of wind-proof hair and gasket of soft rubber is inserted into the packing insertion groove111at a time without cutting the packing member, and possibly fitted by turning, to thereby enhance heat insulation, air-tightness, and soundproof.

The outer circumference of the curved brace window frame edge connection fitting105is planar and perpendicular and differs from the inner circumference thereof of the curved shape. The reason why the outer circumference of the curved brace window frame edge connection fitting105is due to the fact that an opening portion of an architecture building where a window is installed is formed of a rectangular or square shape. That is, for a working convenience, only the inner circumference of the window frame edge connection fitting is curved.

InFIG. 5, a curved brace116is formed in the curved brace window frame edge connection fitting105, and a screw8engaged with the horizontal bar102passes through a screw hole109of the curved brace window frame edge connection fitting105and protrudes. Likewise, although it is not shown inFIG. 5, a screw engaged with the vertical bar103passes through a screw hole of the curved brace window frame edge connection fitting105and protrudes in the case of a vertical axis (not shown). In coupling, protrusions110are inserted into the horizontal bar102and the vertical bar103, and then screws8having passed through the screw holes109are assembled into screw grooves107formed in the horizontal bar102and the vertical bar103. This is the same as that of the conventional art. As the length of the edge connection fitting gets longer, the screws8have been engaged into the screw grooves107, and then part of the space in the screw holes109can be filled with a cover118made of the same material as that of the fabricated window frame.

FIG. 6is a perspective view showing a coupling relationship of part of a curved brace window sash edge connection fitting105awhich is used for a slider according to an embodiment of the present invention.

A raised step106aon the inner circumference of the curved brace window sash edge connection fitting105ais curved. In particular, a glass groove117ainto which glass is fitted is perpendicularly formed so that glass can be conveniently cut. If a curved glass groove is extended up to the portion of the glass groove117aof the curved brace window sash edge connection fitting105a, glass is curvedly cut. Thus, a working time is delayed and a manpower cost increases. Accordingly, the glass groove is perpendicularly formed so that glass can be swiftly cut and inserted into the glass groove.

The outer circumference of the curved brace paired edge connection fitting105ais formed of a curved plane corresponding to the curved brace window frame edge connection fitting. Screw holes (not shown) are formed as in the curved brace window frame edge connection fitting. Here, protrusions110aare fitted into the horizontal bar102aand the vertical bar103a, and then are assembled with screws. This is the same as that of the conventional art. Also, packing insertion grooves111aformed in the horizontal bar102aand the vertical bar103aare formed in a curved structure on the outer circumference of the curved brace paired edge connection fitting105a. Accordingly, a window sash can be fitted while turning without cutting the packing members such as mohair16acalled wind-proof hair (not shown) and gaskets made of soft rubber. As a result, a working time can be shortened and heat insulation, air-tightness, and soundproofing can be enhanced. The protrusions110aprotrude from the contact surfaces of the paired edge connection fitting105a, and are formed in structures appropriate for sliders, respectively. That is, the protrusions110aare inserted into the horizontal bar102aand the vertical bar103a, in order to make the horizontal bar102aand the vertical bar103afirmly coupled with the edge connection fitting105a.

FIG. 7is a perspective view showing a curved brace window sash edge connection fitting, a horizontal bar, and a curved brace window frame edge connection fitting, which are used for a slider according to an embodiment of the present invention. InFIG. 7, it can be seen that the curved brace window sash edge connection fitting105aslidingly moves through the horizontal bar102and a raised step106of the curved brace window frame edge connection fitting105. Wheels (not shown) smoothing a sliding operation can be mounted on the outer circumference of the paired edge connection fitting. InFIG. 7, the same reference numerals as those ofFIGS. 4 and 6denote the same elements as those ofFIGS. 4 and 6.

FIG. 8is a perspective view showing a coupling relationship of a curved brace window frame edge connection fitting which is used for a casement according to an embodiment of the present invention.

A stopper222is formed in a casement but is not formed in a slider. When a window sash is closed, the window sash contacts the stopper222. That is, the stopper222absorbs impact occurring when the window sash is rotated, and is closely involved with heat insulation and air-tightness.

A curved brace216is formed in the casement in the same structure as that of the brace116used in the slider. The curved brace is a diagonal reinforcement member, which effectively disperses a pressure which is diagonally applied to the curved brace216, to thus structurally stabilize the window frame of the casement.

The curved brace window frame edge connection fitting of the casement is curved in the same manner as those formed in the horizontal bar202and the vertical bar203. Protrusions210are also formed in the curved brace window frame edge connection fitting205, to thus firmly couple the horizontal bar202and the vertical bar203, and auxiliary protrusions220are also formed therein to thus heighten accuracy of coupling. Since a coupling method of the curved brace window frame edge connection fitting205is same as that of the conventional art, the detailed description thereof will be omitted. A reference numeral207denotes a screw hole inFIG. 8.

FIG. 9is a perspective view showing a coupling relationship of part of a curved brace window sash edge connection fitting205awhich is used for a casement according to an embodiment of the present invention, which is viewed from the front side, andFIG. 10is a perspective view which is viewed from the rear side inFIG. 9.

A raised step206aon the inner circumference of the curved brace window sash edge connection fitting205ais curved. In particular, a glass groove217ainto which glass is fitted is perpendicularly formed.

The outer circumference of the curved brace paired edge connection fitting205ais formed of a curved plane corresponding to the curved brace window frame edge connection fitting205. That is, the curved brace window sash edge connection fitting205ashould be of a curved structure so as to face the curvature radius of the curved brace window frame structure edge connection fitting205.

As described above, the outer circumference of the curved brace paired edge connection fitting205ais formed of a curved plane, and screw holes (not shown) are formed in the outer circumference of the curved brace window sash edge connection fitting205a, as spaces into which screws are fitted. The screw holes (not shown) are formed in the same manner as that ofFIG. 5which is a cross-sectional view of the window frame edge connection fitting105. The curved brace window sash structure edge connection fitting205ahas a structure that a raised step206a, a glass groove (not shown), and a packing insertion groove114having the same shapes as those of the raised steps206a, the glass grooves217a, and the packing insertion grooves211aformed in the horizontal bar202aand the vertical bar203aare curved. Differently from the window sash of a slider, the curved brace window sash edge connection fitting of a casement bringing a stopper into contact has a structure that packing insertion grooves are formed in one direction and thus the window is rotated by means of a hinge or a hinge arm so as to be opened and closed. The window sash also performs such a rotational function to bring a stopper of a window frame into contact so that the window sash is closed.

Referring toFIG. 10, a packing member (not shown) fitted into the a packing insertion groove of the vertical bar are fitted into packing insertion grooves of the horizontal bar along the packing insertion grooves of the curved edge connection fitting, and then fitted with the curved edge connection fitting again. Then, the packing members (not shown) are fitted into the vertical bar, the curved edge connection fitting, the horizontal bar, and the curved edge connection fitting, to then be fitted into the vertical bar which has been inserted initially. A window sash coupling method is same as that of the conventional assembly method, and has been described above. Accordingly, the detailed description thereof will be omitted. A reference numeral211adenotes a packing member.
