DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel-like fitting member suitably used for furniture such as doors and sliding doors, and fittings.

[0002]

2. Description of the Related Art Conventionally, panel-type fittings of this type have conventionally been made of a wooden board or a wooden bar, and a core such as a wooden veneer, decorative paper, cloth, or a synthetic resin sheet. A sheet to which a sheet is attached is widely used.

[0003]

However, there is a problem that the fitting member having the above structure is heavy and requires a complicated process for its manufacture.

[0004]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above-mentioned problems of the prior art, and has a plate-like base material having a notch at an arbitrary position on both sides of a wooden edge. Pieces which are respectively fitted in the cutouts of the plate-shaped base material, and a core material which is composed of reinforcing bars provided over the entire width of the upper and lower edges of the plate-shaped base material,
A surface decorative material adhered so as to cover both edges of the core from the surface of the core material to reach a part of the rear surface, and a back surface adhered to the rear surface portion of the core material to which the surface cosmetic material is not adhered A decorative material, wherein the plate-shaped base material is made of laminated corrugated cardboard or synthetic resin foam, and both the surface decorative material and the back surface decorative material are coated on the surface of a plate-shaped material such as a wooden material, an inorganic material or a synthetic resin material. A fitting member characterized in that a sheet is attached thereto.

[0005] As the plate-like base material of the core material, laminated cardboard or synthetic resin foam is preferably used. The laminated corrugated cardboard is one in which single-sided corrugated cardboard or double-sided corrugated cardboard is arbitrarily combined and laminated to a predetermined thickness.

Notches for fitting pieces are provided at arbitrary positions on both sides of the edge of the plate-shaped base material. These cut-outs are provided when a laminated cardboard is used as the plate-shaped base material. May be formed after forming them, or may be formed by laminating each of the corrugated boards before lamination while matching notches formed in advance.

A piece to be fitted at an arbitrary position on both edges of the plate-shaped base material and reinforcing bars provided over the entire width of the upper and lower edges of the plate-shaped base material, respectively, are plywood, laminated wood, laminated veneer. Wood material such as wood, particle board, fiberboard,
Alternatively, inorganic materials such as lightweight cellular concrete and calcium silicate plate are particularly preferably used.

Examples of the surface decorative material and the back surface decorative material include wood materials such as plywood, particle board, fiberboard, and laminated veneer, inorganic materials such as calcium silicate, glass wool and rock wool, and synthetic resin materials. Those in which a decorative sheet such as a wooden veneer, a decorative paper, a cloth, a decorative synthetic resin sheet, a decorative metal sheet, or the like is adhered to the surface of the plate-like body are particularly preferably used.

On the back side of the surface decorative material, grooves having an L-shaped cross section are formed at positions corresponding to the corners of the plate-like base material of the core material, thereby facilitating bending at the grooves. Can be. This bending groove may be formed so as to leave a part on the surface side of the plate-shaped body of the surface decorative material, or formed over the entire thickness of the plate-shaped body so as to leave only the surface decorative sheet. Is also good.

The front decorative material and the back decorative material are adhered to the outer peripheral surface of a core material composed of a plate-shaped base material, a bridge material and a reinforcing bar using an adhesive. As the adhesive used,
Synthetic resin adhesives such as vinyl acetate resin, urea resin, epoxy resin, urethane resin, isocyanate, and acrylic resin are suitable, and are used alone or as a mixed adhesive obtained by arbitrary mixing. The adhesive is applied to the back surface of the front facing material and the back facing material, the front surface of the core material, or both.

[0011] After forming the laminated panel body in this way, by pressing and bonding, the fitting member of the present invention is obtained.

[0012] A chamfer may be formed at the upper end of a portion which becomes the edge of both sides of the plate-like base material constituting the core material. In this case, similarly, the chamfered portion is formed also on the bridge member to be fitted into the notch of the plate-shaped base material and the reinforcing bar provided at the edge of the upper and lower trees, and the surface decorative material has the chamfered portion. Is also applied so as to cover.

When laminated cardboard is used as the plate-like base material of the core material, the laminated cardboard itself is not formed with a chamfered portion, but is formed only with the bridge member and the reinforcing bar, and the surface decorative material is wound. It is also possible to form a chamfer on the laminated corrugated board-like substrate by the compressive force at the time of sticking.

When the fitting member is an interior door or the like that requires a hinge as its mounting bracket, a cutout and a piece fitted in the cutout are arranged at least at the hinge mounting position on the hinge mounting side. In the above, the bridge member is arranged at a position facing the hinge mounting position or at an arbitrary position. In the case where the fitting member is one in which a pivot bracket is attached up and down like a closet door of a shaft hanging type,
Pivot fittings are attached to the upper and lower reinforcing bars, and pieces are arranged at arbitrary positions on both sides of the rim. Further, it is preferable that a notch is formed at a position where a handle, a handle, or the like is attached, and a piece is fitted into the notch.

[0015]

A cutout is provided at an arbitrary position on both sides of the edge of the plate-like base material, and a piece is fitted thereto. Reinforcing bars are provided at the upper and lower edges of the edge to form a panel core material. Since the strength and thickness accuracy of the plate-shaped base material are improved by the bridge member and the reinforcing bar, a lightweight material such as a laminated cardboard can be used as the plate-shaped base material.

[0016]

1 and 2 show the structure of a closet door according to an embodiment of the present invention, in which three notches 2 are provided at three corresponding positions on both side edges of a laminated corrugated cardboard 1, respectively. Each of the bridge members 3 is fitted with a reinforcing bar 4 at the edge of the upper and lower trees.
Are joined to form a panel core material. Chamfered portions 5 are provided at the upper ends of both edges of the panel core material.

A surface decorative material 6 is adhered from the surface of the panel core material so as to cover both sides of the edge including the chamfered portion 5 and reach the back side, and a back surface decorative portion is not adhered to the back surface side where the surface decorative material is not adhered. Material 7 is stuck.

The closet door of this embodiment is of a pivot hanging type, and reference numeral 8 in FIG. 1 denotes a concave hole into which a pivot bracket (not shown) is inserted. The closet door is used as a pair of left and right folding doors, with a hinge (not shown) attached to the position of the notch 3 on the edge of the wooden edge shown on the upper side in FIG. Although not shown, when a handle is attached, a piece is also arranged at the attachment position.

[0019]

According to the present invention, while using a lightweight plate-like base material such as laminated corrugated cardboard or synthetic resin foam, it is provided on the pieces to be fitted into the cutouts on both sides of the rim and on the upper and lower rims. The strength and thickness accuracy can be greatly improved by the reinforcing bar.

The fittings of the present invention can be easily handled and workable by reducing the weight, and the cost can be reduced by simplifying the manufacturing process.
