DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel used for architectural door materials such as partition panels, folding doors, sliding doors, hinged doors or furniture doors such as closet storage, entrance storage and cabinets.

[0002]

2. Description of the Related Art As a decorative panel of this type, there is known a flash panel in which decorative panels are attached to both sides of a frame structure formed by combining a vertical frame, a horizontal frame, a vertical rail, a horizontal rail, a breeding tree and the like. It is. Further, a flash panel in which a drop-in opening is formed on both surfaces or one surface (front surface) of the flash panel to improve the design is widely used.

As a frame material used for a frame structure of a flash panel, a solid material, a compressed material, or the like is generally used, and a wooden edge thereof is decorated with a molding. As a decorative panel adhered to the front and back surfaces of the frame structure, a wooden decorative panel having the same material and dimensions is generally used. Similarly, in the case of a decorative panel in which openings for dropping are formed on both sides, the same wood-based decorative board of the same material and dimensions is stuck on the front and back sides of the frame structure, but in the case of single-side dropping, the material is Even if it is the same, a plurality of divided decorative boards or decorative boards with cut-out openings cut out are attached to the surface of the frame structure, and a single decorative board is used on the back side, Decorative boards having different dimensions are attached to the front and back surfaces, respectively.

A decorative plate such as a wooden decorative plate, a glass plate, or a mirror plate, which is the same as or different from the decorative plate attached to both sides of the frame structure, is fitted into the drop opening.

[0005]

As described above, in the decorative panel of the prior art with a single-sided drop, the decorative panels adhered to the front and back surfaces of the framed structure have greatly different dimensions. For this reason, even if the material of the front and back decorative boards is the same and the shrinkage and expansion characteristics under environmental conditions such as temperature, humidity, and heat are substantially the same, the degree of deformation such as warpage of the decorative boards on the front and back sides is large. In contrast, the front and back balance is lost, which causes the door to be deformed.

Once the door has been deformed, there are disadvantageous drawbacks such as rattling during opening and closing of the door, making opening and closing operations difficult, and a gap at the time of closing, resulting in poor sealing performance and poor appearance. .

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention solves the above-mentioned problems in the prior art, and provides a decorative panel having a novel structure in which deformation such as warpage does not occur even when a drop-in opening is formed on one side. The purpose is to:

That is, the present invention relates to a decorative panel in which a decorative panel is adhered to the front and back surfaces of a frame structure having a frame member as a core material, wherein the decorative panel has a drop-in opening formed on the front surface side and the decorative panel rear surface side. On the inner side of the decorative panel, a groove is formed substantially at least in a position substantially corresponding to the upper and lower edges of the drop-in opening on the decorative panel surface side in the width direction of the decorative panel.

[0009]

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Wood, plywood, medium or hard fiber board, particle board, flake board, etc. A composite board obtained by singly or arbitrarily laminating a wafer board, a strand board, a stick board, a veneer laminated material, a laminated material, etc., and optionally cutting it into a rod-shaped substrate is used. These rod-shaped substrates are assembled into a frame structure using an adhesive, nails, wood screws, tuckers and the like.

[0011] The frame structure may be a single frame having four peripheral edges formed by vertical and horizontal frames, a double frame composed of an outer peripheral frame including vertical and horizontal frames and an inner peripheral frame, or a vertical frame. Can be adopted as a single frame and a horizontal frame is a double frame, and a single frame and a double frame are combined.

The decorative panel of the present invention has a decorative panel attached to each of the front and back surfaces of the above-mentioned frame structure, and has a drop-in opening formed on the front surface thereof. For this reason, a step is formed inside the vertical frame and the horizontal frame of the frame structure. The step portion is formed by using a vertical bar or a horizontal bar made of a bar material thinner than the frame material, or formed by cutting out the inner surface side of the surface of the frame material. The position of the step portion is determined by the size, number, position, and the like of the decorative plate adhered to the drop-in opening.

[0013] The decorative plate attached to the front and back sides of the frame structure is
Plywood, medium or hard fiber board, particle board, flake board, wafer board, strand board, stick board, laminated veneer, laminated board, etc. After applying a base treatment such as a filling treatment, a sealer treatment, a siding treatment, a undercoating treatment as required, a veneer veneer, an artificial veneer, a decorative paper,
It can be obtained by attaching a decorative sheet such as a decorative cloth, a decorative synthetic resin film or sheet, or a synthetic resin impregnated paper. The decorative sheet may be subjected to optional coloring, pattern printing, transfer printing, and the like.

Further, if necessary, a surface protective layer such as a top coat or a transparent synthetic resin film may be formed on the surface of the decorative plate to improve the surface strength and wear resistance.

It is preferable that the decorative sheet used for the decorative panel is the same as the decorative panel attached to the front and back surfaces of the decorative panel. Here, the same means that the materials have substantially the same physical properties with respect to environmental conditions such as temperature, humidity, humidity, heat, and the like, and particularly that they have similar contraction and expansion characteristics.

At the drop-in opening on the front side of the decorative panel, similarly to the decorative plates adhered to the front and back surfaces of the frame structure, plywood, medium or hard fiber board, particle board, flake board, wafer board, Strand board, stick board, veneer laminate, laminated wood, etc. are used alone or as a composite board with any laminate as the base material. The obtained decorative board is fitted. On the front side of the frame structure, drop the decorative board and cut it out using a router to match the size and shape of the opening and provide a drop-in opening, and stick it to the drop-in opening using this cut-out decorative board Is also good. Alternatively, a decorative plate such as a glass plate, a mirror, or a metal plate which is different from the decorative plate attached to the front and back surfaces of the frame structure may be dropped and fitted into the opening.

A groove is formed on the inner surface of the decorative panel attached to the back side of the decorative panel in parallel with the width direction of the decorative panel. Comparing the shrinkage and expansion of the front and back decorative panels of the decorative panel, even if they are the same material, since one decorative panel is stuck on the back side over the entire decorative panel, Deformation such as warpage due to shrinkage and expansion is significantly exhibited as compared with the decorative plate on the front surface side. However,
In the decorative panel of the present invention, the widthwise groove formed on the inner surface of the backside decorative panel absorbs the contraction and expansion of the backside decorative panel, and is similar to the contraction and expansion of the front side decorative panel,
The contraction and expansion characteristics of the decorative plates on the front and back sides are well-balanced, and deformation such as warpage can be suppressed.

The number of grooves can be formed at an arbitrary interval such as upper and lower ends and a central portion in the longitudinal direction (longitudinal direction) of the decorative panel at an arbitrary interval. It is formed at a position substantially corresponding to the upper and lower edges. In addition to the pair of grooves, a groove may be additionally formed at an arbitrary position.

The number and depth of the grooves can also be arbitrarily determined in consideration of achieving the above-mentioned effects, but in general, a relatively deep groove is excellent in absorbing deformation such as warpage. Therefore, a single or a small number of grooves may be used, while a relatively shallow groove requires a certain number of grooves. Considering the design, if the groove is formed too deep, the groove may be seen through from the surface of the decorative plate, and therefore it is preferable to use a relatively shallow groove.

The length of the groove can be arbitrarily set. For example, the groove can be extended over substantially the same length as the width of the upper and lower edges of the drop-in opening in the front side decorative plate. It is formed so as to extend over the entire width of the side decorative plate. Further, the groove may be formed in a double line or other multiple lines, a broken line, a dotted line, or a combination thereof.

The width of the groove is also arbitrary, but is generally about 1 to 5 mm, and usually about 3 mm in order to achieve the above-mentioned effects.

The groove may have an arbitrary cross-sectional shape such as a V-shape, a U-shape, an R-shape or a concave shape.

A molding having nails, tuckers, adhesives, etc., having a flange on the back side, preferably covering a part of the frame surface, is provided on the stepped portion provided in the drop opening of the decorative panel on the front side of the decorative panel. Any means may be used alone or in combination.

The molding is made of wood, plywood, medium or hard fiber board, laminated veneer, etc., optionally cut, plastic extruded, bent metal, etc. A decorative sheet such as a decorative paper, a decorative cloth, a decorative synthetic resin sheet, a decorative veneer, an artificial veneer, or the like is adhered to the surface of the decorative sheet.

Further, in the frame structure in which the front and back decorative boards are adhered, an edge-attaching material covering the front and back decorative boards at the opening of the front and back decorative boards can be attached to the open ends of the vertical and horizontal frames. A decorative sheet such as a decorative paper, a decorative cloth, a decorative synthetic resin sheet, a decorative impregnated paper, a decorative veneer, an artificial veneer, or the like is used as the bordering material.
