Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a frame which is a core material of a door panel.

[0002]

2. Description of the Related Art A conventional door panel framework is assembled by installing a horizontal timber frame material between vertical timber frames on both sides and placing a tucker between the vertical frame material and the lateral frame material. .

[0003]

However, when a door panel is formed by pasting a surface material on a frame composed of a vertical frame member and a horizontal frame member made of wood, the door panel is warped due to changes in temperature and water content. It may occur. In order to prevent this warpage, it is conceivable to install a metal reinforcing material along the vertical frame material to reinforce the vertical frame material to prevent warpage.However, a metal reinforcing material is installed along the outer surface of the vertical frame material. When installed, the vertical frame member and the horizontal frame member cannot be joined by placing the tucker.

Further, there is one disclosed in Japanese Patent Laid-Open No. 5-1491 which reinforces a vertical frame member so that a tacker can be set. In this structure, a groove is formed in the longitudinal frame member in the longitudinal direction, and a reinforcing material is embedded in the groove. In such a conventional example, even if the vertical frame member is reinforced with a reinforcing member, it can be joined by tucking, but it is necessary to process the recessed groove for burying the reinforcing member in the vertical frame member and also to bury it. There is a problem that the process becomes complicated, and since a reinforcing material is embedded inside, it is not possible to place a tucker with a deep driving depth, and the connection between the vertical frame material and the horizontal frame material becomes weak. There is a fear.

The present invention has been made in view of the above-mentioned points. The vertical frame member is reinforced with a metal reinforcing member to prevent warpage, and the vertical frame member is easily reinforced. It is an object of the present invention to enable the vertical frame member and the horizontal frame member to be joined by a tucker even if is reinforced with a metal reinforcing material.

[0006]

In order to solve the above-mentioned problems, the framework of the door panel according to the present invention has a structure in which a plurality of horizontal wood frame members 2 are erected between the vertical wood frame members 1 on both sides of the door frame. Reinforcing members 3 which are made of metal and have a U-shaped cross section are fitted on the outer surfaces of the frame members 1 facing each other over the longitudinal direction of the vertical frame members 1, and the end portions of the horizontal frame members 2 of the reinforcing members 3 are fitted. A notch 4 is provided in a portion corresponding to, and a tucker 5 is driven between the vertical frame member 1 and the horizontal frame member 2 at the notch 4 portion to be connected. By mounting the reinforcing member 3 on the vertical frame member 1 in the longitudinal direction of the vertical frame member 1, it is possible to reinforce the vertical frame member 1 and prevent warpage. By fitting and mounting the metal reinforcing member 3 having a U-shaped cross section on the outer surface of the vertical frame member 1, the reinforcing member 3 can be easily mounted and reinforced on the vertical frame member 1. Even if the reinforcing member 3 is attached to the outer surface of the vertical frame member 1, the notch 4 is provided in the reinforcing member 3 so that the tucker 5 can be easily inserted between the vertical frame member 1 and the horizontal frame member 2 to be joined. it can. Further, since the tucker 5 for the vertical frame member 1 is driven from the notch 4, the tucker 5 having a deep driving depth can be driven, and the vertical frame member 1 and the horizontal frame member 2 can be firmly joined.

Further, the notch 4 is provided with a reinforcing member 3 having a substantially U-shaped cross section.
It is also preferable that it is provided so as to extend over two adjacent surfaces. Further, it is also preferable that a cutout 6 is provided in a portion of the reinforcing member 3 which does not correspond to the horizontal frame member 2 and the cutout 6 serves as a hinge attachment portion. In this case, the hinge can be easily attached even if the vertical frame member 1 is reinforced with the metal reinforcing member 3.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a frame as a core material of a door panel is composed of vertical frame members 1 on both left and right sides and horizontal frame members 2 installed between the vertical frame members 1. The vertical frame member 1 and the horizontal frame member 2 are made of wood. The horizontal frame member 2 is composed of an upper frame member 2a at the upper end, a lower frame member 2b at the lower end, and an intermediate middle frame member 2c. The reinforcing member 3 is formed into a long product having a U-shaped cross section by bending a metal plate. The reinforcing member 3 is provided with a notch 4 at a position corresponding to a position where the reinforcing member 3 is connected to the horizontal frame member 2. As shown in FIG. 3, the notch 4 is provided so as to extend over two surfaces of the reinforcing material 3, one flange and the web. Further, the notch 4 is easily formed by punching or the like when the reinforcing material 3 is formed by bending the metal plate. The reinforcing members 3 are fitted and mounted on opposite sides of the vertical frame members 1 so as to extend in the longitudinal direction of the vertical frame member 1, but the reinforcing members 3 of the vertical frame member 1 are fitted. The thickness of the metal plate of the reinforcing material 3 is cut in a portion, and the outer surface of the vertical frame material 1 and the outer surface of the reinforcing material 3 are flush with each other while the vertical frame material 1 is fitted with the reinforcing material 3. There is. The tucker 5 is placed between the vertical frame member 1 and the horizontal frame member 2 at the notch 4 in a state where the vertical frame member 1 and the end portion of the horizontal frame member 2 are butted against each other.
And the horizontal frame member 2 are joined. At this time, there is a step between the striking face of the tucker 5 of the horizontal frame member 2 and the striking face of the tucker 5 of the vertical frame member 1 exposed from the notch 4, but the notch 4 is provided so as to extend from the flange to the web. The vertical frame member 1 and the horizontal frame member 2 can be reliably joined by reliably placing the tucker 5 on. In this way, the surface decorative material 7 is attached to the entire outer surface of the frame assembled as shown in FIG. 1 to form the door panel A as shown in FIG.

FIG. 5 shows another embodiment. In the case of this example, notches 6 are provided in the reinforcing material 3 other than the place where the tucker 5 is placed. The notch 6 serves as a portion to which a hinge is attached when the surface decorative material 7 is attached to the frame to form the door panel A.

[0010]

As described above, according to the present invention, the vertical frame member is provided with the metal reinforcing member having a substantially U-shaped cross section in the longitudinal direction of the vertical frame member, so that the vertical frame member is reinforced with the reinforcing member. It is possible to prevent the entire warp from occurring, and moreover, since the metal reinforcing material having a U-shaped cross section is fitted on the outer surface of the vertical frame member, the reinforcing material can be easily mounted on the vertical frame material. Since a notch is provided in the reinforcing material, a tucker can be easily installed between the vertical frame member and the horizontal frame member even if a metal reinforcing member is attached to the vertical frame member for reinforcement. In addition, it is possible to insert a tucker into the vertical frame material from the notch and to insert a tucker with a deep penetration depth to strengthen the vertical frame material and the horizontal frame material. It can be combined.

According to the second aspect of the present invention, since the notch is provided so as to extend over two adjacent surfaces of the reinforcing material having a substantially U-shaped cross section, the tucker is driven from the notch. When the tucker does not hit the metal reinforcement,
The tacker can be placed smoothly and reliably. Further, in the invention according to claim 3 of the present invention, since a notch is also provided in a portion of the reinforcing material that does not correspond to the horizontal frame member, and this notch portion is used as the hinge attachment portion, the vertical frame member is made of metal. Even if it is reinforced with the reinforcing material, the hinge can be easily attached.
