Description

Window frame {Window frame}

The present invention relates to a window frame, in particular, by manufacturing a different frame made of metal and a synthetic resin material to create a free space in the interfitting parts to combine the composite resin even if the thermal expansion coefficient occurs in the size of the two frames due to the temperature difference It relates to a window frame that prevents the ash frame from being broken.

In general, various houses, apartments, officetels, shopping malls, offices, etc., are provided with a number of windows for the purpose of passage, ventilation, and skylight, and glass doors for distinguishing a veranda, a kitchen, and a multipurpose room. Is universal.

These windows or glass doors form an installation space of a certain height on the wall to construct a door frame frame having a rail on the inner wall of the installation space, and install a plurality of glass doors that are slid along the rail of the frame inside the door frame frame. Is the most common structure.

In particular, in recent years, it is common to fabricate such a frame with aluminum material. Due to the characteristics of the door frame frame extruded with aluminum, the indoor temperature is different from the room temperature to a high or low temperature, thereby causing heat loss. Since it occurs largely, it is common to fix the insulation panel made of foamed resin or the like on the surface of the interior frame, which is one side of the door frame frame.

The insulation panel is extruded and produced using resin such as wood and foamed resin such as MDF having excellent thermal insulation effect, and the extruded material is cut into a predetermined length as needed, and the insulation panel as described above. Not only doubles the insulation effect that suppresses condensation and heat loss due to the indoor and outdoor temperature differences of the door frame frame, but also forms various patterns and designs on the outer surface of the indoor chassis to make the design more beautiful, further enhancing the interior decoration effect. It is to improve the role.

By forming various types of patterns and designs on the outer surface of the indoor chassis to have a more beautiful design to play a role to further enhance the interior decoration effect.

Such a coupling structure between the frame and the insulation panel typically adopts a sliding fastening method or a jointing method using an adhesive. In the case of the sliding fastening method, an “T” shaped insertion protrusion is formed on the interior side of the frame and the heat insulating material panel is used. In the corresponding surface of the "T" shaped insertion groove is formed by sliding the fastening of the insulation panel from one end of the frame.

However, the frame as described above has a problem in that the frame width is widened by forming a structure in which a pair of metal frames are connected with a heat insulating material.

In addition, the frame is made of a metal material, the metal frame is located on the indoor side has a good aesthetics and has a need to attach a separate synthetic resin frame for insulation, after a long period of use has a problem that the frame and the synthetic resin frame is separated. .

In addition, the frame has a problem in that thermal expansion or thermal contraction occurs when heat or cold air acts on the metal frame, and deformation occurs in the synthetic resin frame having different thermal expansion or thermal contraction coefficients.

Therefore, the composite frame is inserted into the metal frame positioned outside on the outside without using a separate insulating material, and is placed on the indoor side to secure the aesthetics of the room while the strength is reinforced by the metal frame. The method of manufacturing the frame and the frame of the window or door frame that is combined by the fastening method used and the synthetic resin frame is combined by the heat fusion method to improve the integrity and increase airtightness and heat insulation.

Depending on the shape and structure of the outer coupling end 13 and the inner coupling end 23 can be implemented differently.

In this, the frame 100 in the outdoor frame 100 performs a reinforcement function for the resistance and support for horizontal force, vertical force or torsional external force, the indoor frame 20 is made of polyvinyl chloride to enable various coloring Excellent aesthetics, there is a feature that performs the function of insulating material to prevent the cold air or heat transmitted from the outdoor frame 10 to be delivered to the room.

As shown in Figure 6a to 6b, as such, the completed frame 100 is constructed by cutting the length so that the indoor frame 20 has a fusion length (L) for thermal fusion than the outdoor frame 10 .

That is, the inner cutting end 23 of the outdoor frame 10 and the indoor frame 20 is cut by the first cutting blade 40, and the indoor frame 20 is cut by the second cutting blade 50. Cut.

At this time, the fusion length (L) is configured in the range of 1.5 ~ 3mm to be melted during thermal fusion by the fusion length (L).

This, the fusion length (L) is located along the longitudinal direction of the combined outdoor frame 10 and the indoor frame 20, the first cutting blade 40 is located in the rear, based on the first cutting blade 40 It is produced by the cutting of the second cutting blade 50 positioned to advance by the fusion length (L).

Thus, the frame 100 is cut to have a fusion length (L) is a frame 100 which is located in the horizontal direction after cutting both sides inclined or horizontally cut to produce a rectangular frame form to produce a window or door frame To prepare a pair, a pair of frames 100 located in the longitudinal direction.

Subsequently, in the state where the pair of horizontal and vertical frames 100 are arranged in a quadrangular form, the interior frame 20 is preferentially bonded in a thermally fusion manner in a horizontal state in which it is melted by applying heat to the fusion length L. The indoor frame 20 is bonded to each other by the molten liquid by pressing so that the direction and the vertical direction is in contact with each other at a right angle to combine the indoor frame 20.

Next, in order to combine the outdoor frame 10 is combined in the following example combination method.
