Description

Composition wood wrapped natural veneer and its manufacture method and door flame using it}

The present invention is to form a groove on the other side of the synthetic timber wrapped with natural veneer on one side and the manufacturing method and the other side of the synthetic wood wrapped on the natural veneer on one side and then folded along the groove in the corner of the wrapping material The present invention relates to a door frame made of synthetic wood wrapped with natural veneer on one side to prevent bursting of natural veneer and to simplify construction.

Conventionally, the door frame is composed of solid wood as one of the methods for producing the door frame, but the price of the wood is not only very expensive but also difficult to obtain by relying on the total amount of imports. There is also a disadvantage of lack of unity due to color and texture.

Therefore, in order to make up for the shortcomings of the wood as the door frame material, the door frame frame, which is generally widely used now, has been developed and used, which is relatively inexpensive and can be produced domestically.

Such MDF is made by crushing the waste materials (wood) and mixing with the adhesive to form a gel state and then compression molding to have a certain thickness by a compressor, the thickness is at least 1㎜ 3, 6, 9, 12, 15, 20, 25, 30, 35 mm.

On the other hand, the MDF itself is a compression molding of the gel state, so that the appearance aesthetics of the MDF itself are inferior, so that wrapping products are attached to the outer surface of the MDF itself so as to have a certain aesthetic feeling.

The wrapping material is covered with various patterns such as PVC foil, finishing foil, natural veneer, etc. in various windows and doors, and has long been used in Europe and the like.

As a technique known as a method for manufacturing a door frame of MDF using such a wrapping material, Korean Patent Publication No. 2001-0007829 (Invention name: Method of manufacturing a simple door frame and a simple door frame produced by the method), Utility Model Registration Number No. 0242631 (designated name: door frame frame and door frame fitted to the door frame).

1A and 1B are cross-sectional views of a door frame using MDF as a known technique in Korean Patent Publication No. 2001-0007829 (name of the invention: a method of manufacturing a simple door frame and a simple door frame produced by the method), and FIGS. 2b is a cross-sectional view of the door frame frame as a technique known from Utility Model Registration No. 0242631 (the name of the design: the door frame frame and the door frame fitted to the door frame).

Here, FIG. 1A is a cross-sectional view of the state of the door frame deployed, FIG. 1B is a cross-sectional view of the state of the simple door frame folded and fixed to the door frame, FIG. 2A is a cross-sectional view of the state of the door frame frame deployed, FIG. It is a cross-sectional view of folding state and fixing to the frame.

As shown in FIGS. 1A and 1B and 2A and 2B, the door frames 1 and 11 of these inventions and designs include door frame bodies 3 and 13 and stoppers 8 and 18 made of MDF, Wrapping materials 2 and 12 are attached to one surface of the bodies 3 and 13.

However, the door frame and the manufacturing method in these inventions and designs used natural veneer as a wrapping material, but after attaching the natural veneer having a thickness of 0.3 ~ 0.5mm to the door frame body, when folding the body in the form of a door frame As the natural veneer is bent at the bent portion of the door frame, a problem arises.

This is because the hardness of natural veneer is greater than that of PVC foil and finishing foil, and there is almost no ductility. In some cases, you may lose the value as a product that makes the texture of solid wood.

In addition, in the door frame of FIG. 1B, when the divided door frame bodies 3 are folded to form the door frame 1, the other surfaces of the door frame bodies 3 divided by the adhesive applied to the other surface of the door frame body 3 are mutually different. Attached to form the door frame (1), the upper portion forming the door frame (1) is fixed only by the adhesive is to lose the bonding force.

In addition, in the door frame 11 of FIG. 2B, although the nail or takapin 19 is fixed to the inner surface of the stopper mounting groove in which the stopper 18 is to be located, the door frame 11 is fixed to the frame 15, In this case, the door frame body 13 located between the two stopper mounting grooves is not only hard to nail or takapin 19, but also easy to break the door frame body at both ends in this process.

The present invention is provided in order to solve the problems of the prior art as described above, the synthetic wood wrapped natural veneer on the outer surface to feel the texture of the wood and the method of manufacturing such synthetic wood, and such natural veneer It is an object of the present invention to provide a door frame using a synthetic wood wrapped with natural veneer that performs the function of the door frame in a state where the natural veneer attached to the outer surface does not burst even after folding the synthetic wood.
