Description

  The present invention relates to a joinery and a manufacturing method thereof.

In wooden buildings such as wooden houses, wooden fittings are often used as fittings used to open and close the entrances and exits of buildings and rooms.
In addition, as a wooden fitting, what is called a flash door in which face materials such as plywood are pasted on both sides of a core made of a wooden core material is known. Adhesion of decorative sheets such as synthetic resin sheets is performed.
As a manufacturing method of a joinery whose surface is finished with a decorative sheet, for example, a decorative sheet is pasted on each of two face materials, and they are fixed to both sides of a core, and then the left and right and up and down of the decorative sheet Then, a synthetic resin rim sticking material called a major material or the like is attached to the left and right ends of the wood to obtain a joinery.

  However, there is a problem that a cost is required for a synthetic resin material or the like used as an edge sticking material (major material or the like).

With regard to makeup for joinery, Patent Document 1 discloses that two makeup panels formed by applying a makeup material on the front surface and performing V-cut processing for bending on the back surface are used as the base material constituting the inner core of the joinery. Affixed and bent at the corners of the base material and bent so that both ends of the two decorative panels are inserted into the grooves provided on both side surfaces of the base material, and bent at both ends A joinery in which two pieces are fitted together is described.
Further, in Patent Document 2, when a decorative sheet is used in which a plurality of printing belt-like portions having different designs or colored colors are provided in a divided state, the boundary portion is immersed in the adjustment recess, It describes that the positional deviation and distortion of the boundary part are concealed from the outside so as to be invisible.

By the way, in recent years, from the viewpoint of improving customer satisfaction with colors and designs, we have prepared multiple options that customers can select as fixture colors and designs when building new houses or replacing fixtures. In addition, it is also done to produce joinery of the color and design selected by the customer.
However, as in the case of the conventional joinery manufacturing method described above and the joinery of Patent Document 1, after attaching a decorative sheet or the like to a face material or a decorative panel, it is attached to a core structure to manufacture the joinery. In some cases, it takes a long time to complete the fittings according to the customer's wishes after receiving the order, resulting in problems such as a prolonged construction and renovation period. In this regard, if makeup products with various colors and designs are manufactured in advance, there will be no problem of prolonging the construction period, but from the viewpoint of waste of fixtures that are not selected by the customer, storage location issues, etc. There is a problem such as having to limit the number of options.

  The thing of patent document 2 is easy to produce a stain | pollution | contamination near the edge part of the sheet | seat which exists in the surface of a fitting, since the site | part immersed in an adjustment recessed part is not the edge part of a decorative sheet.
