Abstract

Disclosed is a jamb assembly for a door having a novel structure, capable of representing a wooden feel and reinforcing the strength for a specific region by improving the structure of the jamb assembly coupled with an opening of a wall surface for the installation of the door. The jamb assembly is installed along an inner peripheral surface of an opening of a wall surface for installation of a door and constituting a door frame. The jamb assembly includes an outer skin section constituting an outer portion of the jamb assembly and having a surface molded with various patterns such as a wooden pattern, and a body core section surrounded by the outer skin section, constituting an inner frame portion of the jamb assembly, and fixedly coupled with the opening of the wall surface for the installation of the door.

Claims

1. A jamb assembly installed along an inner peripheral surface of an opening of a wall surface for installation of a door and constituting a door frame, the jamb assembly comprising:

an outer skin section constituting an outer portion of the jamb assembly and having a surface molded with various patterns such as a wooden pattern; and

a body core section surrounded by the outer skin section, constituting an inner frame portion of the jamb assembly, and fixedly coupled with the opening of the wall surface for the installation of the door.

2. The jamb assembly of claim 1, wherein the body core section includes a surface having a plurality of concavo-convex patterns in opposition to the inner peripheral surface of the opening of the wall surface for the installation of the door.

3. The jamb assembly of claim 2, wherein the body core section is extrusion-molded by using polyvinyl Chloride or acrylonitrile Butadiene Styrene copolymer.

4. The jamb assembly of claim 2, wherein the body core section includes a fire-resisting product including ceramic wool.

5. The jamb assembly of claim 1, wherein the outer skin section includes one selected from the group consisting of sheet molding compound, bulk molding compound, and thermoplastic resin.

6. The jamb assembly of one of claims 1 to 5, further comprising a support core section interposed between the outer skin section and the body core section and including a thin metallic plate to reinforce strength of the body core section.

7. The jamb assembly of claim 6, wherein the support core section includes an iron material or a thin aluminum plate and is curved to cover a portion of the surface of the body core section surrounded by the outer skin section.

8. The jamb assembly of claim 1, wherein the jamb assembly includes a first jamb assembly coupled with a hinge, a second jamb assembly facing the first jamb assembly and coupled with a door lock, and a third jamb assembly coupling top ends of the first and second jamb assemblies to each other and forming a top surface of a door frame,

wherein the outer skin section of the first jamb assembly is provided on a surface thereof with a groove coupled with the hinge, and

wherein the outer skin section of the third jamb assembly is provided on a surface thereof with a coupling hole coupled with the hinge.
