Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved corner structure of a veneer furniture,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curved corner structure of furniture laminated with a veneer sheet laminate on a wood panel and a method of manufacturing the same. In particular, by forming a curved corner by bending a wood panel, cracks or breakage of the laminated veneer sheet In addition, it enhances the visual effect of wood furniture feel.

In general, natural wood is used for household and office furniture and various household goods. In particular, the natural wood has excellent design and texture, and its texture and texture are excellent, and the wood is utilized in various industries and fields .

Such natural wood has a relatively high unit price and has limitations in the production characteristics of wood. Therefore, there are considerable limitations in manufacturing various shapes and designs, and in recent years, natural wood logs have been cut thinly in the form of paper materials, Wood furniture made by bonding paper to wood panels has been developed.

Compared to the sheet made by artificial wood patterning, the natural wood veneer is bonded to the wood panel, and the furniture surface can feel the texture and texture of the natural wood, and the visual design effect .

On the other hand, as the edges of the furniture such as a desk, a table, and a table used in a home or an office are exposed to the joint part of the wood, the visual design effect is deteriorated. Therefore, It is a tendency to produce by processing in form.

In the prior art documents related to the curved edges of furniture in which such a patterned sheet is bonded, there is known a prior art reference of Korean Patent Registration No. 10-1144818 entitled " Furniture and Partition Corner Curved Surface Cutter and Corner Curved Surface of Furniture & Processing method ".

In the above-described conventional method, the sheet is processed in a rounded manner so as to round the outer surface of the sheet at a time of bending the sheet about the bent groove by machining the sheet into a bent groove in the state of leaving the sheet, So that the corner can be easily curved.

In addition, the designation of the 'V-shaped grooved joining panel capable of grooving the V-groove' in the Korean Registered Trademark No. 20-0339690 of the Republic of Korea provides a veneer joint panel having the texture and dignity of a high-grade veneer while using a veneer, In addition, the present invention provides a laminated wood panel having functionality such as antibacterial, directional, stain resistance and scratch resistance, if necessary.

However, when the corners of furniture such as the above-mentioned conventional desk are fabricated by curving, damages and breakage such as cracks of the veneer adhered to the corners are frequent and the defect rate is increased.

In addition, there is a need to develop and attempt to develop a manufacturing method of a furniture that can meet the demand of a consumer seeking a natural and old-fashioned pattern and design of a wooden furniture.

In order to solve the above-mentioned problems, the present invention provides a wood panel with grooves and bending to form curved edges, thereby preventing cracks or breakage of the bonded natural veneers and minimizing the defective rate, And to enhance the visual and decorative effect of the design.

The present invention relates to a method for manufacturing a curved corner structure of a furniture in which a woodpile is joined to a wood panel,

A knot pattern joining step of firmly adhering and joining veneers on the front surface of a wood panel using an adhesive;

A surface grinding step of grinding the surface of the non-woven fabric laminated on the wood panel using a grinder so that the surface of the non-woven fabric is three-dimensionally projected and recessed according to the pattern;

A bent groove forming step of forming a bent portion of the wood panel 20 to a thickness of 0.5 to 1 mm by cutting or stepping the wood panel to a depth of 4.5 to 9 mm so as to have a predetermined depth of groove;

A bending step of bending the edge of the wooden panel having the bent groove at a right angle by using a bending machine;

A stiffener joining process for rigidly connecting and securing a half-hoop-shaped stiffener to the rear surface of the bent portion of the bent wood panel;

.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, cracks or breakage of the laminated natural veneer sheet is prevented by forming a curved edge by bending the wood panel with grooves, so that the defect rate can be minimized and the productivity can be improved , Which is an advantageous invention for providing furniture of an old-fashioned and beautiful pattern and design of wood.

FIG. 1 is a sectional view showing a wood panel according to the present invention, FIG. 2 is a sectional view showing the curved corner structure of the wooden furniture of the present invention, and FIG. 3 is a flowchart showing an embodiment of the present invention.
In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings.
In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the present invention relates to a laminated wood panel 10 having a pattern of natural wood, a wood panel 20 for bonding the laminated wood 10 to the front surface, And a stiffener 30 that is engaged with the rear surface of the folded portion of the panel 20.

The veneer sheet 10 is formed so as to be joined to a wood panel by a thin plate, and the surface thereof is formed so as to be protruded and recessed in three dimensions according to a wood pattern.

The wood panel 20 is formed to be adhered to the entire surface of the wood panel 10, and a bent groove 21 having a certain depth is formed on the rear surface.

Preferably, the thickness of the wood panel 20 is 4.5 to 9 mm, the thickness of the bent portion formed with the bending grooves is 0.5 to 1 mm, and the MDF is a medium density fiberboard (MDF).

The stiffener 30 is formed in an arcuate shape so as to be coupled to the bent groove 21 on the rear surface of the wood panel 20.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

(S1)

The surface roughness paper 10 is firmly adhered to the front surface of the wood panel 20 using an adhesive.

Surface polishing step (S2)

The surface of the green sheet 10 joined to the wood panel 20 is polished using a grinder.

At this time, since the soft tissue is recessed and polished more than the hard tissue depending on the density and the strength of the surface texture of the rough surface paper 10, the surface of the rough surface paper 10 is projected and recessed three-dimensionally according to the pattern.

The bending groove processing step (S3)

The wood panel 20 is formed to have a bent portion of 0.5 to 1 mm in thickness by cutting or stepping so that the back surface of the wooden panel 20 having a thickness of 4.5 to 9 mm is provided with the bent groove 21 having a predetermined depth.

The bending step (S4)

The edge of the wooden panel 20 provided with the bent grooves 21 is bent at a right angle using a bending machine.

Stiffener joining process (S5)

When the half-hoop-shaped reinforcing member 30 is joined to the rear surface of the bent portion of the bent wood panel 20, the bent portion of the wooden panel 20 can be firmly and stably maintained.

The foregoing description is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention.

Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
