DESCRIPTION

(NAME OF PATENT)

COMPOSITE WINDOW SASH

(TECHNICAL FIELD)

This invention is for window, especially for composite window sash made it by PS panel of inside surface and made it by Aluminum panel of outside surface to combine by pressing method.

Generally, Composite window is composed of Aluminum and wood, PVC, recycled styrene form as like report No. 97-3384 of utility model, report No. 92- 8906 of utility model, report No. 20-0283678 of utility model, report No. 20- 0163582 of utility model, and patent report No. 10- 0309793.

REPORT NO. 97-3384 OF UTILITY MODEL

This composite window has a groove and salient to combine with Wood and Aluminum part each other, but it can be disjoined without using the glue, so this kind of composite window using the glue has a weak point which is tied with wood and aluminum part for 48hours during hardening of glue.

REPORT NO. 92-8906 OF UTILITY MODEL

This structure has assembling part by pressing method, but it should be use by screw for combining with wood and aluminum , and it is complicate for assembling because it is limited as assembling part by connection sill, and also not productivity to complicate for assembling.

And also, wood panel has corrupted and bended by condensation owing to difference of temperature from outside, and it is not smoothly operated and make the virus and mildew to harm to human body, and the processing and other fee is high cost that it not easy to using this by consumer.

REPORT NO. 20-0283678 & 20-0163582 OF UTILITY MODEL, REPORT NO. 10-0309793 OF PATENT

This composite window has made with aluminum and wood or plastic, as like the drawing No. 2 & 3, it is fixed to No. 1 of decoration material(22) on No. 1 of aluminum sash(21 ), and stick to adhesion surface(23) on adhesion part, and make groove(24) in a part of No. 1 of decoration material for supporting, and make salient(25) in a part of No. 1 of aluminum sash(21 ), and then assembled by inserting a salient to groove.

This composite window is composed that the outside surface made from aluminum and the inside surface made from wood and PVC, recycled styrene,

so it has good merit which has excellent insulating, soundproofing & waterproofing effect and good design as decoration.

But, if it doesn't use the glue, it will be a gap widens to Arrow A and take off to Arrow B, and also it takes time to solid at least 48hours to make no productivity, to discharge a toxic gas,

(BACKGROUND ART)

This composite window is composed that the outside surface made from aluminum and the inside surface made from wood and PVC, recycled styrene, so it has good merit which has excellent insulating, soundproofing & waterproofing effect and good design as decoration.

As the above mentioned, wood panel has corrupted and bended by condensation owing to difference of temperature from outside, and it is not smoothly operated and make the virus and mildew to harm to human body, and the processing and other fee is high cost that it not easy to using this by consumer.

And also, the window which is used PVC as inside surface isn't expandable, so it has weak point that are low than PS panel for insulation and soundproof, and also high cost than PS panel.

The window which is composed that the outside surface made from aluminum and the inside surface made from PS by using recycled styrene can make the injury to human body, and also it can be bended by difference temperature between outside and inside to reduce the effect of soundproof, insulation, etc.

(DISCLOSURE OF INVENTION)

The combining method of existing window is used by glue to combine with polystyrene to aluminum , and it made the toxic gas and it can be bended by difference temperature between outside and inside to reduce the effect of soundproof, insulation, waterproof.

This idea is based on the principle that is made the composite window by pressing method.

It isn't using the glue and combined exact by roller system , and so the measure of frame is uniformed that can be assembled exact with 4sides of vent, and it doesn't happened to bend by contraction and expansion as pressing method without using the glue, and it doesn't need the time to hardening of glue, and so it can increase the product and supply early.

It can be minimized the gap of vent and frame by exact assembling to protect the outside air to inside and also it can be maximized the insulation and

soundproof.

(BRIEF DESCRIPTION OF DRAWINGS)

Drawing No. 1 is the formation of existing window.

Drawing No. 2 is the cross section to draw the composite window by example. Drawing No. 3 is the cross section to draw the composite window by example. Drawing No. 4 is the cross section to draw the composite window by this patent.

The details for drawing and mark

As drawing No. 4, this patent is for composite window which is composed that the outside surface made from aluminum and the inside surface made from PS. But, the difference with existing composite window is the connection method as like that is using the glue or combines by pressing.

It make the bending part on top and bottom of No. 2 of aluminum sash, and then combined with No. 1 & 2 of pressing connection part in No. 2 of decoration part by pressing method.

The above pressing connection part is composed the bending part as salient and groove as the enlargement of the drawing No. 4, and it can be combined by elasticity and pressing easily because the bending part has made by symmetry in every direction of aluminum sash.

Therefore No. 2 decoration part(32) doesn't separate from No. 2 aluminum sash(31 ) by any force.

The assembling method is as follows.

It makes the pressing connection part on top and bottom of No. 2 aluminum sash(31 ) and makes the groove on No. 2 decoration part(32), and then No. 2 decoration part(32) will be combined to No. 2 aluminum sash(31 ) with the

above pressing connection part and groove which isn't use the glue, just by pressing, and so it can supply the excellent window and balcony sash which has best insulation effect and soundproof.

(BEST MODE FOR CARRYING OUT THE INVENTION)

The purpose of this patent is to satisfy of durability and decoration for window sash, especially balcony.

When the metal part and polystyrene part will be combined by the glue, it will happen to make the toxic gas and formaldehyde.

But, if it will be use by pressing connection method as this patent, it can complement for the above matters.

(INDUSTRIAL APPLICABILITY)

This patent is difference with existing composite window which is connected the wood, PVC to metal part by glue.

It has a merit of convenience and economic that be combined by automatic for processing compare with other processing, and can protect the formaldehyde and toxic gas.

The composite window which is using the pressing method is productivity and reduce the cost and also it has best insulation effect and soundproof, and it can be operated softly to open the window by protect the twist and decay owing to moisture.

The connection by pressing can supply the productivity to reduce the hardening time of glue(normally, it takes 48hours), and it can be recycled by take off the No. 2 decoration part(32) from No. 2 aluminum sash(31 ).
