Description

[Detailed Description of the Invention] [Technical Field] This invention relates to an arch frame device such as an interior door frame.

[Background technology]

BACKGROUND ART Conventionally, an arch-shaped door frame A having an arcuate upper portion as shown in FIG. 1 has been widely used in order to enhance the decorative effect of a room. When constructing such an arch-shaped door frame A, as shown in FIG. The arch-shaped opening frames 11a, 11a of the wall material 12 consisting of the fitting grooves 10
a, 10a to attach the arch-shaped frame base material 10 to the wall material 12, and decorative edges 14, 14 are attached to the corners formed by the outer surface of the wall material 12a and the outer peripheral surface of the arch-shaped frame base material 10. This was fixed with nails 15 along the line.

As a result, the heads of the nails 15 are exposed on the surface of the decorative edge 14, which is not only unsightly, but also gaps tend to form between the wall material 12 and the decorative edge 14, resulting in an unsightly appearance.

Furthermore, in order to avoid inconvenience in fixing the decorative edge 14 by driving the nails 15, the arch-shaped frame base material 10 needs to have a large width, which also has the disadvantage of increasing the amount of materials used and the cost. It was hot.

[Purpose of invention]

The purpose of this invention was to prevent gaps from forming between the wall material and the decorative edge, improve the appearance, and reduce the cost by reducing the width of the arch frame base material. The purpose is to provide equipment.

[Disclosure of invention]

The arch frame device of this invention is arranged inside an arch frame opening frame formed in a wall material along the arch-shaped opening frame, and has an arch-shaped opening frame with a fitting groove provided on the outer peripheral surface along the longitudinal direction. A frame base material, a horizontal flange portion having a protrusion on the lower surface that fits into a fitting groove of the arch-shaped frame base material, and a horizontal flange portion that stands up from the horizontal flange portion and has an outer surface as a decorative surface and is provided on the outside of the wall material. and a decorative edge formed of a vertical flange portion located on the arch-shaped frame base material, the decorative edge being arranged along the longitudinal direction on the outer circumferential surface of the arch-shaped frame base material and having both end portions hidden below the floor surface close to each other. The decorative edge is bent along the outer circumferential surface of the arch-shaped frame base material by being pulled in the direction, and the vertical flange portion is bent toward the outer surface of the wall material.

As described above, according to this invention, the decorative rim is arranged along the outer circumferential surface of the arch-shaped frame base material disposed inside the arch-shaped opening frame, and both ends of the decorative rim are arranged in the direction of approaching each other. Since the decorative edge is stretched and bent along the outer circumferential surface of the arch-shaped frame base material and the vertical flange portion is bent toward the outer surface of the wall material, the bent vertical flange portion is bent toward the outer surface of the wall material. It is possible to prevent a gap from forming between the outer surface of the wall material and the vertical flange, and there is no need for nailing to fix the decorative edge as in the conventional method. Since the nail heads are not exposed, it is possible to prevent the resulting arched door frame from deteriorating in appearance.

Also, since nailing is not required to secure the decorative edges,
It is no longer necessary to increase the width of the arched frame base material as in the past, and the amount of material used and cost can be reduced.

Embodiment An embodiment of this invention will be described based on FIGS. 3 to 5. That is, as shown in FIGS. 3 and 4, this arch frame device is disposed inside an arch-shaped opening frame 2a formed in a wall material 2 along this arch-shaped opening frame 2a, and is arranged on the outer peripheral surface. Arch-shaped frame base material 1 provided with a fitting groove 9 along its longitudinal direction
and a horizontal flange portion 4a whose lower surface is the protrusion 6 that fits into the fitting groove 9 of this arch-shaped frame base material 1; Vertical flange section 4 located on the outside
b, the decorative edge 4 is arranged along the longitudinal direction on the outer peripheral surface of the arch-shaped frame base material 1, and the ends thereof hidden below the floor surface are arranged in a direction in which both ends thereof approach each other. The decorative edge 4 is bent along the outer circumferential surface of the arch-shaped frame base material 1 by pulling it, and the vertical flange portion 4b is bent toward the outer surface of the wall material 2.

The wall material 2 is composed of a pair of face materials 3, 3 such as plywood.

As shown in FIG. 5, the decorative edge 4 has an L-shaped cross section consisting of a horizontal flange portion 4a and a vertical flange portion 4b, and as shown in FIG. Both decorations are arranged on both sides of the outer peripheral surface of the frame base material 1, and the protrusions 6 provided on the lower surface of the horizontal flange portion 4a are fitted into the fitting grooves 9 provided on both sides of the arch-shaped frame base material 1. Position edges 4,4. Further, the horizontal flange portion 4a is sandwiched between the arch-shaped opening frame 2a of the wall material 2 and the arch-shaped frame base material 1.

As shown in FIG. 5, the tension spring 8 is connected between both ends of the decorative edge 4 by wrapping both ends around nails 5 attached to both ends of the decorative edge 4 hidden under the floor surface 7. It is constructed such that it is constructed so as to be stretched between both ends thereof. In this case, it is necessary that the nails 5 be driven only into the decorative edge 4 and not reach the arched frame base material 1 on the lower surface so as not to interfere with the tensioning of the tension spring 8.

In this way, by bending the decorative edge 4 in an arch shape along the outer peripheral surface of the arch-shaped frame base material 1, the vertical flange portion 4b of the decorative edge 4 in the arch portion
Because a force acts on its upper end to reduce its radius, it bends outward or inward and tries to fall down. Therefore, by pressing the upper end of the vertical flange part 4b by hand, or by making the opening angle between the horizontal flange part and the vertical flange part slightly smaller than 90 degrees in advance, the vertical flange part can be moved to the inside, i.e. It is possible to prevent the plywood 3 from falling down toward the outer surface and creating a gap between the decorative edge 4 and the wall material 2.

Also, nail the decorative edge 4 to the arch-shaped frame base material 1.
Since there is no need to fix the arch frame base material 1 to the base material 1, there is no need to expose the nail heads and spoil the appearance, and there is no need to increase the width of the arch frame base material 1.

[Effect of idea]

According to this invention, a decorative rim is arranged along the outer peripheral surface of an arch-shaped frame base material disposed inside an arch-shaped opening frame, and a tension spring is used to pull the decorative rim between both ends of the decorative rim. Since the vertical flange is bent toward the outer surface of the wall material, the bent vertical flange comes into contact with the outer surface of the wall material, preventing a gap from forming between the outer surface of the wall material and the vertical flange. Moreover, since conventional nailing is not required to fix the decorative edge, the nail heads are not exposed on the surface of the decorative edge, which improves the appearance of the resulting arched door frame. It has the effect of preventing it from becoming worse.

Also, since nailing is not required to secure the decorative edges,
It is no longer necessary to increase the width of the arched frame base material as in the past, and the amount of material used and cost can also be reduced.
