Abstract

PROBLEM TO BE SOLVED: To provide a wood soundproof flush door manufactured with high productivity and at a low cost in a normal wood flush door factory by forming a frame body formed of wood core meterial, inside an outer frame, and clamping sound insulating sheets by the frame body from both front and rear faces to attach them. SOLUTION: Previously cut sheets formed of asphalt rubber containing cast iron powder are prepared as sound insulating sheets 4. Decorative paper with printed patterns is stuck to MDF and stuck with an adhesive to the front and rear outer surfaces of an outer frame 2 and a frame body formed of wood core material 3. After manufacturing the frame body formed of the wood core material 3 by sticking it to the outer peripheral surface of the outer frame 2, the sound insulating sheets 4 are clamped, fittingly mounted into the outer frame 2 and fastened. Edge material is further stuck after the manufacturing process of sticking surface material to the front and rear faces of the outer frame 2 and the frame body formed of the wood core material 3, cutting and NC machining. Mass production and cost reduction can therefore be attained, and the damage to a saw blade can be prevented since only a part of the outer frame is cut in a cutting process for accurate dimensional adjustment.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden soundproof flash door having excellent soundproofness in a house or an office.

[0002]

2. Description of the Related Art A soundproof door disclosed in, for example, Japanese Utility Model Publication No. 61-9998 is known as a soundproof door of a house or an office. In this soundproof door, in a door having a mirror plate, both the frame portion and the mirror plate portion have a flash structure having a hollow inside, and a soundproofing material is provided at a substantially central portion in the thickness direction of the door over the entire frame portion and the mirror plate portion. And a soundproof layer in which a plate body such as plywood is disposed on both sides, and a hollow portion is interposed on both sides of the soundproof layer.

[0003]

As described above, the conventional wooden soundproof door is provided with a sound insulation performance by providing a core material with a gypsum board, a sound insulation sheet, glass wool, or the like. In a normal wood-flush door factory, there is a problem in that special specifications are required, and productivity is low and prices are high.

[0004] In particular, the sound insulating sheet has poor cutting properties, and there is a problem that chips are attached to the saw or the saw blade is damaged in some cases. Accordingly, an object of the present invention is to solve the above-mentioned problems in the prior art and to provide a wooden soundproof flash door that can be manufactured at high productivity and at low cost in a normal wooden flash door factory.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to provide:
A flash door in which the front and rear surfaces of an outer frame are covered with decorative panels, wherein a frame made of a wood core material is formed inside the outer frame, and a sound insulation sheet is sandwiched between the front and rear surfaces by the frame. Solved by wooden soundproof flash doors.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described above.
Wood soundproof doors can be manufactured with high productivity by the usual flash door manufacturing process. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings according to a preferred embodiment.

[0007]

1 is a front view of a wooden soundproof door according to the present invention, and FIG. 2 is a partially enlarged cross-sectional view thereof. 1 and 2, reference numeral 1 denotes a wooden soundproof flash door, which is formed by fitting and bonding a vertical and horizontal outer frame 2 and a frame made of a wooden core material 3 inside the outer frame 2. .

In this embodiment, the frame made of the wood core material 3 is assembled in a ladder shape as shown in FIG.
The front and rear pair is fitted and bonded inside the outer frame 2. A pair of frames made of the wood core material 3 sandwich the sound insulation sheet 4.

As means for sandwiching the sound insulating sheet between a pair of frames made of the wood core material 3, in this embodiment, as shown in FIG. 2, means for attaching the sound insulating sheet 4 with the wood core material 3 using an adhesive. Has been adopted. However, the present invention is not limited to this method, and may be, for example, stapling by a tucker.

The outer frame 2 is, in this embodiment, LVL
(Laminated Veneer Lumber). However, the present invention is not limited to this, and solid wood and other ordinary wood materials can be used. Further, in this embodiment, the wood core material 3 uses a particle board. However, for example, LVL, MDF (Medium Density Fiberboard), or other wood materials can be used.

The sound insulating sheet 4 is prepared as a sheet cut into a predetermined size in advance. In this embodiment, a sheet made of asphalt rubber containing cast iron powder is used. In practicing the present invention, the present invention is not limited to this, and a material composed of a material having a high specific gravity of an inorganic filler mixed with a flexible material having no air permeability can be used.

For example, powders such as iron powder, lead powder, iron oxide powder, various ferrites, lead oxide powder, barium sulfate powder and the like, and fibrous materials based on various rubbers and synthetic resins such as vinyl chloride and polypropylene resin. And the like mixed with an inorganic filler having a high specific gravity.

Reference numeral 5 denotes a decorative plate. In this embodiment, a decorative plate having a printed pattern attached to an MDF is used. The decorative board 5 may be made of a material known per se, such as a decorative plywood, in addition to the decorative board of this embodiment. Thus, in this embodiment, the decorative plate 5 is the outer frame 2.
And it is stuck on the front and rear outer surfaces of the frame made of the wood core material 3 via an adhesive.

Reference numeral 6 denotes an edge material (end face decorative material). In this embodiment, a material obtained by attaching a printed sheet to an extruded product of an ABS resin is used. In addition to those in this embodiment, it is possible to use an edge material known per se such as, for example, a synthetic resin extruded product or a product obtained by attaching decorative paper to the surface of a thick letter. In this embodiment, the edge member 6 is attached to the outer peripheral surface of the outer frame 2 via an adhesive.

The wooden soundproof flash door 1 of the present invention has a frame made of a wooden core material 3, sandwiches and fixes a sound insulating sheet 4, fits and fixes in the outer frame 2, and the outer frame 2 of the surface material 5. It is manufactured by a process of sticking (flashing), cutting (cutting), and NC working to the front and rear surfaces of the frame made of the wood core material 3, and the edge material 6 is stuck to obtain a product.

[0016]

As described above, the present invention is constructed as described above, so that it can be produced by a normal woody flash door manufacturing process in a normal woody flash door manufacturing factory.
This has the effect of enabling mass production and significant cost reduction resulting therefrom. Further, in the cutting process for obtaining a full size, it is only necessary to cut a part of the outer frame, so that the sound insulating sheet is not cut, and no chips are attached to the saw blade or the saw blade is damaged.
