Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided in an opening such as a doorway of each room or passage formed inside a building such as a building or a house, and supports a door of the doorway of these room or passage. The present invention relates to a wooden opening frame used as a door frame, a passage frame, or a decorative frame, and a manufacturing method thereof.

[0002]

2. Description of the Related Art Inside a building, a room is partitioned or a passage is constructed. Further, a door, a passage frame or a decorative frame is provided for the purpose of decorating the room. An opening is formed in the partition wall, a door frame is attached to this opening, and the door frame is supported and attached. The opening frame provided in the opening inside such a building is usually installed between the left and right vertical frames that are erected along the left and right side edges of the opening and the upper ends of these left and right vertical frames. The upper frame located along the upper edge of the opening, and further, if necessary, attached between the lower ends of the left and right vertical frames, the lower frame located along the lower edge of the opening, and the door. As for the frame, door stop is attached along the inner surface longitudinal direction of the left and right vertical frames and the upper frame as needed. In addition, with respect to such an opening frame, its expected width (when it is attached to the wall opening, the width dimension in the wall thickness direction) mainly depends on the wall thickness dimension of the partition wall forming the opening, or Since it is decided from a design point of view like a makeup frame, it is necessary to easily adjust the expected width, and since it is exposed to the outside and touches the human eye, it has an excellent appearance and the expected width adjustment processing. The wooden ones that can be used are preferred.

By the way, in recent years, there has been an increasing demand for not only the function of partitioning a room or passage but also the function of heat insulation, flameproofness, sound insulation, etc. to be added to a partition wall of a building, especially a general house. Accordingly, the wall thickness dimension of the partition wall forming the opening tends to vary. For this reason, even for the opening frame attached to the opening of such a partition wall, there is an increasing demand for a wooden frame whose adjustable width can be adjusted. However, it is becoming increasingly difficult to obtain the Lauan wood that is normally used to manufacture this wooden opening frame, and as a result, there is an unavoidable situation in which price increases are inevitable, and it is an inexpensive alternative to Lauan wood. There is a demand for the development of an opening frame that uses fine wood and is capable of adjusting the width of the prospect.

Therefore, conventionally, a core material is formed by individually or a plurality of inexpensive natural board materials or synthetic board materials such as lauan veneer lumber (LVL), medium density fiber board (MDF), particle board and hard board. Then, an opening frame is formed by bonding a thin surface decorative plate, a synthetic resin decorative sheet, or a thin single plate to the surface of the core material.

However, when the former thin surface decorative plate is used, the thin surface decorative plate is subjected to so-called V-cut processing by a V-cut machine while leaving the synthetic resin decorative sheet on the surface. While bending using the V-cut groove, it is attached to the surface of the core material to form a frame material,
This frame material is processed to form the opening frame, but in this case, the positioning work of the blade of the V-cut machine in the V-cut processing is extremely troublesome, and once set, mass production is performed. If this is not the case, it will not be profitable, and if there is a frequent need for adjustment processing of the prospective width, there will be a problem that it will not be possible to handle it at all.

When the latter synthetic resin decorative sheet or thin veneer is used, it does not matter if the surface shape of the opening frame to be manufactured is a simple square shape, but this surface shape is compared. If it becomes complicated or you want to give rounded corners, you must prepare a roller that matches each surface shape and perform so-called lapping while pressing with this roller. However, there is a problem in that it is not profitable if mass production is not performed after setting once, and it is impossible to cope with it if frequent adjustment of the forecast width is necessary.

[0007]

SUMMARY OF THE INVENTION The present invention was devised in view of such a viewpoint, and an object of the present invention is to use an inexpensive wooden material and to have a rounded corner or the like. It is an object of the present invention to provide a wooden opening frame which is excellent in its appearance and which can be extremely easily adjusted to adjust the prospective width, and a manufacturing method thereof.

[0008]

That is, according to the present invention, the left and right vertical frames are provided upright along the left and right side edges of the opening in the building, and between the upper ends of the left and right vertical frames (or in addition to this, the lower end). An upper frame (or a lower frame in addition to this) which is attached along the upper edge (or the lower edge in addition to this) of the opening, and the vertical frame And the upper frame (or the lower frame in addition to this) is a wooden opening frame formed by adhering a synthetic resin edging material having a thickness of 3 to 8 mm to the fore edge of the decorative plywood.

Further, according to the present invention, the left and right vertical frames are provided upright along the left and right side edges of the opening in the building, and the left and right vertical frames are mounted between the upper ends (or between the lower ends in addition to them), When manufacturing an opening frame including an upper frame (or a lower frame in addition to this) arranged along the upper edge (or the lower edge in addition to the opening) of the opening, a wall of the opening is formed from the decorative plywood. A frame material having a width suitable for the thickness dimension is cut out, and a synthetic resin edging material having a thickness of 3 to 8 mm is attached to the edge of the cut out frame material, and a corner portion of the attached edging material is necessary. Are processed to form a vertical frame material and an upper frame material (or a lower frame material in addition to this), and the vertical frame material and the upper frame material (or a lower frame material in addition thereto) are assembled to form an opening frame. It is a method for manufacturing a wooden opening frame for forming a frame.

In the present invention, the vertical frame and the upper frame or the upper frame and the lower frame which form the opening frame are cut out from the decorative plywood and have a width suitable for the wall thickness of the wall opening. A vertical frame member and an upper frame member or an upper frame member by attaching a synthetic resin edge member having a thickness of 3 to 8 mm to the edge of the frame member and rounding the corner portion of the attached edge member as necessary. And a lower frame member, and the vertical frame member and the upper frame member or the upper frame member and the lower frame member thus formed.

As the decorative plywood used here, for example, inexpensive natural plate materials and synthetic plate materials such as Lauan veneer lumber (LVL), medium density fiberboard (MDF), particle board and hard board are used alone or in combination. An example is one in which a core material is obtained by pasting together and a decorative sheet made of synthetic resin such as polyvinyl chloride is pasted on both the front and back sides. Of these, particularly preferable from the viewpoints of workability and manufacturing cost, a medium density fiberboard as a core material, and a decorative sheet made of polyvinyl chloride having a waterproof / moisture-proof effect on both front and back surfaces thereof, A core material made of inexpensive natural board material or particle board with medium density fiberboard attached on both sides, and a polyvinyl chloride decorative sheet with waterproof / moisture-proof effect is attached on both sides of the core material. Is mentioned.

Using such a decorative plywood, first, a frame material having a width dimension suitable for the wall thickness dimension of the wall opening is cut out. The width of the frame material corresponds to the expected width of the manufactured opening frame.

Next, a synthetic resin edging material having a thickness of 3 to 8 mm is attached to the edge of the frame material thus cut out.
Regarding the thickness of this edge material, if it is thinner than 3 mm, it becomes difficult to perform the rounding. Since it is necessary to perform rounding on the corners of the edge material after sticking, it is desirable that the surface pattern of the edge material does not become unnatural even if it is scraped. Specific examples thereof include Rocantex (special polyvinyl chloride resin) manufactured by REHAU of Germany, Marble Wood manufactured by Panefri Industry Co., Ltd. or Spiral Edge manufactured by Fukubi Chemical Industry Co., Ltd.

In this way, the edge surface of the frame member has a thickness of 3 to 8
mm synthetic resin edging material is attached, and then the corners of this edging material are rounded if necessary, and the vertical frame material, the upper frame material, and the lower frame material used to form the opening frame. To prepare.

When the wooden opening frame to be formed is a door frame, the prepared vertical frame member or upper frame member is then formed with a mounting groove along the longitudinal direction of one side surface thereof if necessary, and this mounting frame is mounted. Attach the door stop using the groove. For this door stop, a mounting ridge is provided along the lengthwise direction, and the mounting ridge is fixed in the mounting groove of the vertical frame member or the upper frame member by using an adhesive or the like. A groove is cut in the frame material and the upper frame material, and a fixing ridge for attaching a door stop made of synthetic resin is driven into the groove and fixed.

The vertical frame member, the upper frame member, and the lower frame member thus formed have their ends vertically passed, horizontally passed, or connected to a toe to form a gate-shaped opening frame. The construction of attaching the opening frame of the present invention to the opening formed in the partition wall of the building can be performed in exactly the same manner as the conventional opening frame.

[0017]

In the opening frame of the present invention, both the front and back sides are covered with the decorative sheet made of synthetic resin on the surface of the decorative plywood, and the edge surface is covered with the synthetic resin edging material. The plywood core material exhibits the waterproof and moisture-proof effect. Further, according to the method of the present invention, the width dimension of the frame material of the opening frame can be freely cut out to prepare the vertical frame material, the upper frame material, and further the lower frame material, thereby forming the opening portion. It is possible to freely and easily set and adjust the expected width of the opening frame that is determined from the viewpoint of design, such as the wall thickness of the partition wall and the decorative frame. It is also possible to easily perform rounding and the like.
