Description

[Detailed description of the invention] [Technical field] This invention relates to an opening frame that is applied to an outer door frame for an entrance door.

[Background technology]

Since the conventional door frame (opening frame) was made of wood, it had the disadvantage that the lower part of the frame was susceptible to corrosion due to humidity.

Therefore, as shown in FIG. 3, a hakama member 9 made of stainless steel or the like is attached to both ends of the lower frame 8, and a wooden vertical frame 10 is attached to the upper surface of the hakama member 9. An upper frame 11 is connected to the upper part of the vertical frame 10.
To attach the vertical frame 10 to the hakama member 9, as shown in FIG.
3, and with the lower end surface of the vertical frame 10 in contact with the plate 13, insert the wood screw 7 into the plate 13 from below.
It was screwed into the vertical frame 10 through the hole 12, and the vertical frame 10 was fixed.

However, since the vertical frame 10 is fixed with its lower end surface placed on the upper surface of the hakama member 9, the fifth
As shown in Figure A, the hakama member 9 was bent and deformed, or as shown in Figure B, a misalignment occurred between the vertical frame 10 and the hakama member 9.

[Purpose of invention]

The purpose of this invention was to stabilize the dimensions of the entire opening frame, improve strength, and improve workability.
Further, it is an object of the present invention to provide an opening frame in which the vertical frame can be firmly fixed and the strength of the hakama member is improved.

[Disclosure of invention]

The opening frame of this invention includes a cylindrical hakama member, a lower frame fixed to the side surface of the hakama member, and both collar pieces arranged in the depth direction of the lower frame and inside the hakama member with the web pieces facing down. a vertical frame having a lower end formed with a convex portion that fits into the groove of the hat-shaped member; a lower end of the vertical frame with the convex portion fitted into the groove; The present invention includes a fixing device that fixes the web piece and both collar pieces from below the hakama member.

That is, this opening frame is fixed integrally with the convex part on the lower end surface of the vertical frame fitted into the groove of the hat-shaped member fitted into the hakama member, so that the vertical frame and the hakama member are fixed together. This eliminates bending and misalignment between the opening frames, increasing the dimensional stability of the entire opening frame and improving its strength.
In addition, the vertical frame is fixed from below the hakama member at three locations, the web piece of the hat-shaped member inside the hakama member and both collar pieces, using fixing tools, so the vertical frame can be firmly fixed. The tool is hidden within the hakama member, improving workability, and furthermore, by fitting the hat-shaped member, the strength of the hakama member is also improved.

An embodiment of this invention will be described based on FIGS. 1 and 2. In FIG. 1, reference numeral 1 denotes a wooden vertical frame, and a convex portion 2 is integrally formed on the lower end surface of this vertical frame 1. On the other hand, a hat-shaped cross-section member 4 as shown in FIG. 2 is fitted onto the upper surface of a hakama member 3 made of stainless steel and attached to the lower end of the vertical frame 1, and has an upward opening that fits into the convex portion 2. A groove portion 5 is formed. The web piece 4a and both collar pieces 4b, 4b of the hat-shaped member 4 are provided with holes 6 through which fixing wood screws are inserted.

When installing the vertical frame 1, fit the convex part 2 at the lower end of the vertical frame 1 into the groove 5 of the hat-shaped member 4 in the hakama member 3, and in that state fix it together with wood screws 7 (fixing tool). do. Therefore, it is possible to prevent bending or misalignment between the vertical frame 1 and the hakama member 3 during fixation, and the dimensional stability and strength of the entire opening frame, which is the door outer frame, is increased. In addition, the hakama member 3
Since I fastened the vertical frame 1 with wood screws 7 from below,
The wood screws 7 are hidden within the hakama member 3, and the wood screws 7 do not get stuck during installation of the opening frame, improving workability. Further, the vertical frame 1 and the hat-shaped member 4 are fixed at three places, the web piece 4a of the hat-shaped member 4 and both collar pieces 4b, 4b, so that the vertical frame 1 and the hat-shaped member 4 are fixed. It can be done strongly. Also,
By fitting the hat-shaped member 4 into the hakama member 3,
The strength of the hakama member 3 itself is improved. Furthermore, since the lowermost end surface of the wooden vertical frame 1 is covered with the plate body 4 having a hat-shaped cross section, it becomes difficult to absorb water and corrosion resistance is improved. Since the other configurations are the same as those in FIGS. 3 and 4, the same reference numerals are given and explanations will be omitted.

[Effect of idea]

According to this invention, the dimensional stability of the opening frame is improved, the strength is improved, the workability is improved, the vertical frame can be firmly fixed, and the strength of the hakama member is also improved.
