Description

[Detailed description of the invention] This invention relates to a door frame material, and its purpose is to a door frame material to which a door can be attached regardless of the thickness of the column or wall of the opening. By providing a door frame material that is attached to one end of the pillar or wall that makes up the depth of the opening, instead of attaching it to the wall, the frame can be attached to one end of the pillar or wall that makes up the depth of the opening. This relates to door frame materials that do not require changing materials.

Furthermore, by making the frame member and the door stop member separable, the head of the nail is hidden when the frame member is attached.

Traditionally, door frames constructed at the entrances and exits of houses, etc. have been made by carving solid wood to dimensions equal to the wall thickness of the opening, which is time-consuming and requires a lot of material. It had the disadvantage of creating waste.

Therefore, since it has become difficult to obtain high-quality materials in recent years, we pasted a decorative sheet on the surface of a wooden substrate such as plywood, provided a V-shaped groove on the back side of the wooden substrate, and bent and glued the V-shaped groove part. It was proposed to use molded frame material.

However, the above-mentioned frame material could not be constructed if the thickness of the pillars and walls that made up the depth of the opening were different.

The present invention has been made in view of the above-mentioned conventional drawbacks.

In other words, the present invention provides three grooves parallel to the side edges of the decorative board at predetermined locations on the back side of the decorative board with a decorative sheet pasted on the surface of the substrate, and wraps the decorative board around a core material having a substantially rectangular cross section. The decorative plank is fixed by bending and gluing the grooves, and the decorative plank is fixed to one side of the decorative plank so as to form a stepped portion on which a wall material or the like can be butted against one side of the core material, Furthermore, on the other side of the decorative plank, the decorative plank is continuously adhered so as to wrap around the other side of the core material to the back surface, forming a stepped portion, and a stepped portion is formed approximately in the center of the surface. Two grooves parallel to the sides of the decorative board are provided at predetermined locations on the back surface of the frame member in which the grooves are formed and the decorative sheet is attached to the surface of the substrate, and the grooves are bent and glued to form a cross-sectional shape. A decorative material formed in the shape of a letter, with a reinforcing material arranged inside it or a door stop member, the width dimension a of the door stop member being approximately equal to the interval b of the grooves formed on the surface of the frame member, This invention relates to a door frame material for attaching to one end of a column or wall, characterized in that the contact member fits into a groove on the surface of the frame member.The most distinctive feature of the door frame material of the present invention is that
It is composed of two members, a frame member and a doorstop member, and on both sides of the frame member, a step portion is formed on the side surface of the decorative plank board and the back surface portion that continues to the other side surface, against which the end of the wall material hits. The decorative board is fixed in such a way that the

Next, the present invention will be explained with reference to the drawings showing one embodiment.

FIG. 1 shows a perspective view of a door frame material according to an embodiment of the present invention. A state in which a door stop member 2 is fitted to a frame member 1 is shown. Frame member 1 is the second
It is produced by the steps shown in FIGS.

The substrate 3 is a commonly used wooden substrate such as plywood, particle board, hardboard, MDF, etc. with a thickness of about 3 mm to 12 mm, and a decorative sheet 4 is adhered to the surface thereof. The decorative sheet 4 may be a synthetic resin film such as a vinyl chloride resin film, synthetic paper, paper,
Single or composite materials such as cloth, nonwoven fabric, and veneer are used.

As shown in FIG. 2, three V-grooves 5, 6, and 7 are provided at predetermined locations on the back surface of the decorative board having the above-mentioned structure to cut the substrate 3 parallel to the sides of the decorative board.

In the case of this embodiment, small convex portions 8 and 9 are provided inside the V-grooves 5 and 6 in order to prevent the bent portion from becoming angular, thereby forming a tapered portion that appears to be chamfered. Then, the decorative board is fixed around a core material 10 having a substantially rectangular cross section as shown in FIG. Make it a thick plate.

Next, a groove 13 parallel to the side surface is formed in the approximate center of the decorative plank, as shown in FIG. 4, to form the frame member 1. Note that the width and number of the grooves 13 may be one groove having the same width as the outside dimension of the door stop member 2 as shown in FIG. 1, but a door stop as shown in FIG. When using member 2, it is necessary to form two parallel grooves with the same width as the decorative board.

In addition, when creating a decorative board by pasting the decorative sheet 4 to the substrate 3, in the subsequent process, the color is applied to the part located approximately in the middle of the groove 13 of the frame member 1 and covered by the door stop member 2. By pasting decorative sheets 4 of different colors, patterns, or materials, the frame member 1 can easily change the color, pattern, or material of its left and right sides.

On the other hand, as shown in FIGS. 5 to 7, the door stop member 2 used integrally with the frame member 1 is attached to the side of the decorative board at a predetermined position on the back surface of the decorative board with the decorative sheet 4' pasted on the surface of the base plate 3'. A decorative material with a U-shaped cross section, with two V-grooves 14 and 15 parallel to each other, and the grooves bent and glued together.
A reinforcing member 16 shown in FIG. 6 is disposed inside it. The reinforcing material 16 may be arranged so as to completely fill the inside of the frame member 1 as shown in Fig. 7, or may be arranged only at the bottom of the U-shape as shown in Fig. 8. good.

Next, an example of use of the door frame material having the above structure will be explained. FIG. 9 shows a cross-sectional view of the door frame material of the present invention with an opening formed therein. That is, the side surface 12 of the frame member 1 to which the decorative board is fixed to the back surface is installed at one end of the pillar 17 of the opening, and the nail 18 is inserted into the groove 13 provided on the surface or from the back surface. After fixing the frame member 1 using an adhesive or a combination thereof, the adhesive is injected into the groove 13, and the door stop member 2 is fitted and fixed.

Thereafter, the wall material 20 is fixed by abutting the end portions of the wall material 20 against the stepped portions X and Y provided on the side and back surfaces of the frame member 1 of the pillar 17 of the opening. In addition, 1 in the figure
9 indicates a door, and 21 indicates a baseboard.

As mentioned above, the frame member of the door frame member for attaching to a column or one end of a wall according to the present invention is made of a decorative plate around the core member so as to form a step on the back side that continues to one side and the other side of the frame member. It is possible to attach wall materials etc. to this stepped part, so it can be attached to one end of a thick pillar or wall, and it can be installed regardless of the thickness of the pillar. The wall material is also placed against the stepped part of the frame member, so it fits well. Further, since the frame member and the door stop member are separated and the door stop member is fitted into the approximate center of the frame member, the heads of nails and rivets are not visible during construction.

Furthermore, by attaching different colors, patterns, or materials of the decorative sheets of the decorative boards constituting the frame member or door stop member, it is possible to coordinate the color tone of both rooms adjacent to the door frame member.

Unlike machined wood, it is molded from plywood or other base materials with less distortion, so it does not cause distortion such as warping and can be mass-produced, providing stable quality door frame materials at low prices. be able to. Compared to conventional products, there is almost no processing required at the work site, and since the decorative sheet is pasted in advance, there is no need for painting at the work site, which has the effect of improving construction efficiency. are doing.
