Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The following description of preferred embodiments is merely exemplary and is not intended to limit the invention, its applications or its uses. In the following drawings, for the sake of brevity, components having substantially the same function are indicated by the same reference numerals.

(Embodiment 1)
FIG. 1 shows how to assemble the opening frame for mounting the door according to the first embodiment. The opening frame 100 according to the present embodiment includes a door end side vertical frame 10, a door tail side vertical frame 20, and an upper horizontal frame 30. A latch receiver 91 is provided in advance on the door end side vertical frame 10.

<Structure of vertical frame, horizontal frame, opening frame>
The door end side vertical frame 10 has a door stop groove 44 for attaching a door stop member and a fixing member for attaching a fixing member for fixing to the wall on the frame inner surface 12 on the side opposite to the surface in contact with the wall. Two types of grooves with the groove 42 are provided. Similarly, the door tail side vertical frame 20 is also provided with a door stop groove 44 and a fixing groove 42 on the inner surface of the frame opposite to the contact surface 21 with the wall. The contact surface 21 is provided with two fixture position displays 48, 48. Although not shown in FIG. 1, the vertical frame 10 on the door end side is also provided with two fixture position displays 48, 48 on the contact surface.

Similarly, a door stop groove 44 and a fixing groove 42 are provided on the inner surface of the frame opposite to the contact surface 31 of the upper horizontal member 30 with the wall.

When the three frames 10, 20 and 30 are connected, it becomes a gate shape, but if such an opening frame 100 is assembled in advance at the factory and transported to the site, it must be transported carefully so as not to be bulky and damaged on the way. , The transportation cost will increase. Therefore, it is common to transport the vertical frame material and the horizontal frame material to the site without connecting them and assemble them at the site. Since the size of the opening of the wall varies depending on each site, long vertical frame materials 10, 20 and 30 horizontal frame materials are prepared, and the length is adjusted to the size of the opening at the site. In this embodiment, the frame members 10, 20 and the horizontal frame members 30 are cut.

<How to attach the opening frame>
In the present embodiment, a cutting step of cutting a part of the door end side vertical frame 10, the door tail side vertical frame 20, and the upper horizontal frame 30 to match the dimensions of the opening, and the door end side vertical frame 10 and the upper horizontal frame 30 The fixing process of fixing the door tail side vertical frame 20 and the upper horizontal frame 30 with the fixing tool (screws), and the fixed door end side vertical frame 10, the door tail side vertical frame 20 and The opening frame is attached to the opening by the attachment step of attaching the upper horizontal frame 30 to the opening.

In the present embodiment, in the door end side vertical frame 10, the upper end side (cutting allowance) 19 is cut because the position of the latch receiver 91 from the lower end is not desired to be changed. The vertical frame 20 on the door tail side may be cut on either the upper or lower side, but here, the lower end side (cutting allowance) 29 is cut. The upper horizontal frame 30 cuts the side (cutting allowance) 39 of the door end side vertical frame 10. In this way, even if the latch receiver 91 is installed in advance at the factory, the opening frame can be formed without returning the distance of the latch receiver 91 from the lower end of the door end side vertical frame 10, so that the latch receiver can be installed on site. There is no need to perform processing (alignment with the door), reducing the labor of construction and shortening the construction time.

After cutting in this way and adjusting to the size of the opening, the door end side vertical frame 10 and the upper horizontal frame 30 are fixed by screws (fixing tools) 52, and similarly, the door tail side vertical frame 20 and the upper horizontal frame 30 are fixed by screws 52. At this time, it is preferable to fix the two grooves 42, 44 at a specific position outside so that the fixing is firmly performed. However, if the screw 52 is screwed in by measuring the position each time at the site, it takes time and the position may be mistaken. In the present embodiment, since the position where the screw 52 is screwed is determined by the fixture position displays 48 and 48, the door end side vertical frame 10, the upper horizontal frame 30, and the door tail side vertical frame are set at the correct fixing position in a short time. The frame 20 and the upper horizontal frame 30 can be fixed.

FIG. 2 shows the end faces of the door stop member attached to the door end side vertical frame 10 and the door end side vertical frame 20. The door end side vertical frame 10 and the door end side vertical frame 20 are formed by laminating a thin decorative material 54 on a part of the surface of a core material 56 made of a wood material such as plywood, LVL, particle board, and MDF. ing. Since the decorative material 54 is attached to improve the appearance, it is not necessary to attach the decorative material 54 to the portion hidden by the wall, the door stop member 92, or the like after construction. The fixture position indications 48 and 48 are formed by providing a groove in the decorative material 54.

FIG. 3 shows an end surface in which the door stop member 92 is attached to the upper horizontal frame 30. The upper horizontal frame 30 is not provided because the fixture position indications 48 and 48 are unnecessary, but other than that, it has the same structure as the door end side vertical frame 10 and the door tail side vertical frame 20. ..

<How to attach the hinge>
After the opening frame 100 is attached to the opening of the wall, a hinge is attached to the vertical frame 20 on the door tail side to fix the opening frame 100. In the present embodiment, the hinge is fixed by a hole forming step in which a hole-drilling auxiliary tool is brought into contact with the door tail side vertical frame 20 to make a plurality of lead holes in the door tail side vertical frame 20, and a screw hole of the hinge is formed. This is performed by a hinge fixing step of fixing the hinge to the door tail side vertical frame 20 with a screw so as to face the lead hole. The position where the hinge is attached is marked in advance on the door tail side vertical frame 20. This mark starts from the end on the opposite side of the cutting allowance 29, and is provided by setting a distance from the end.

FIG. 6 is a diagram showing a hole forming process. In the hole forming step, the hole-drilling auxiliary portion 72 is used. The hole-drilling auxiliary tool 72 protrudes substantially vertically from the plate-shaped member 73 in which a plurality of holes 75 are formed at the same positions as the screw holes arranged in two rows of the hinge, and the end portion of the plate-shaped member 73. It has a positioning member 74. When the plate-shaped member 73 of the drilling aid 72 is brought into contact with the inner surface of the door tail side vertical frame 20 and the positioning member 74 is brought into contact with the side surface 23 of the door tail side vertical frame 20, they are arranged in two rows. The fixing groove 42 is located between the two rows of the holes 75. A lead hole is drilled at the position of these holes 75 using a drill.

Next, as shown in FIG. 7, the drilling aid 72 is removed, the lead hole 25 and the screw hole 71 of the hinge 70 are aligned, and the hinge 70 is brought into contact with the door tail side vertical frame 20. .. Then, as shown in FIG. 8, the screw 51 is screwed into the door tail side vertical frame 20 through the screw hole 71 to fix the hinge 70.

As described above, since the fixing groove 42 is located between the two rows of the holes 75 arranged in two rows of the drilling aid 72, the lead hole 25 is located at the position of the hole 75 of the drilling aid 72. When the lead hole 25 is opened, the lead hole 25 is formed on the outside of the fixing groove 42, and the lead hole 25 does not cover the portion of the fixing groove 42. Therefore, the hinge 70 is firmly fixed to the door tail side vertical frame 20 by the screw 51.

At this time, in FIG. 2, the screw 51 is screwed into the outside of the decorative material 54 constituting the side wall of the fixing groove 42. In the process of screwing the screw 51, the tip of the decorative material 54 is pushed by the screw 51 and receives a force on the center side of the fixing groove 42. Here, assuming that the tip of the decorative material 54, which is the side wall of the fixing groove 42, is at the same position as the lower end 45 of the groove side wall of the fixing groove 42, the tip of the decorative material 54 is deformed and the fixing groove. It is pushed into 42. Before attaching the hinge 70 to the fixing groove 42, a decorative frame described later is fitted. However, if the tip of the decorative material 54 is pushed into the fixing groove 42, the decorative frame is pushed. There is a risk that the hinge 70 will be lifted up and pushed up. However, in the present embodiment, in the fixing groove 42, the decorative material 54 covering the groove side wall extends beyond the groove side wall lower end 45 and into the core material 56, and the tip of the decorative material 54 is embedded in the core material 56. Therefore, the tip of the decorative material 54 is not pushed into the fixing groove 42.

Further, the lead hole 25 can be drilled at an appropriate position simply by bringing the hole drilling auxiliary tool 72 into contact with the door tail side vertical frame 20, and the hinge 70 can be accurately fixed in a short time.

After fixing the hinge 70 to the door tail side vertical frame 20, the door 93 is attached to the hinge 70.

<Comparison between the opening frame of the present embodiment and the opening frame of the reference embodiment>
FIG. 4 is a view showing a state in which the door end side vertical frame 10 of the present embodiment is attached to the wall together with the door 93 from above. The wall has a structure in which a wall panel 60 is stretched on a base material (stud or the like) 62, and the door end side vertical frame 10 is fixed to the base material 62 by a screw (fixing member) 53. The screw 53 is screwed into the portion of the fixing groove 42. After the screwing is completed, the decorative frame 95 is fitted into the fixing groove 42 so as to hide the head of the screw 53 and the fixing groove 42.

FIG. 5 is a view showing a state in which the door tail side vertical frame 20 of the present embodiment is attached to the wall together with the door 93 and the hinge 70 from above. Similar to the door end side vertical frame 10, the door tail side vertical frame 20 is also fixed to the wall base material 62 by screwing the screw 53 into the portion of the fixing groove 42. The head portion of the screw 53 is hidden by fitting the decorative frame 95 into the fixing groove 42.

In order to explain the action and effect of this embodiment, comparison with the reference embodiment will be made with reference to FIGS. 9 to 11.

FIG. 9 is a view showing the door tail side vertical frame 28 according to the reference form. The door tail side vertical frame 28 according to the embodiment has only one groove 43 on the inner surface of the frame, and a screw 53 is screwed into the groove 43 to fix it to the wall, and a door stop member 92 is attached to the groove 43. ing. Since there is only one groove 43, it can be manufactured at a lower cost than the door tail side vertical frame 20 according to the present embodiment. However, since the door stop member 92 is attached and the screw 53 is screwed in at the same position, the following problems may occur.

FIG. 9A is a diagram in which the door tail side vertical frame 28 is installed at an appropriate position in a direction perpendicular to the wall. At this time, the screw 53 penetrates the base material 62 of the wall and is firmly fixed. However, if the vertical frame 28 on the door butt side is displaced to the back side (the side opposite to the side where the hinge is installed) as shown in FIG. 9B, the screw 53 does not penetrate the base material 62 and the door butt The fixing between the side vertical frame 28 and the wall becomes weak. When the door tail side vertical frame 28 is displaced toward the front side (the side where the hinge is installed) as shown in FIG. 9 (c), the screw 53 penetrates the base material 62, so that the door tail side vertical frame 28 There is no problem with fixing the butt to the wall.

On the other hand, in the case of the door tail side vertical frame 20 according to the present embodiment, there is a degree of freedom in setting the position of the fixing groove 42. Therefore, in the direction perpendicular to the wall, the door tail side vertical frame 20 is in an appropriate position in FIG. 10 (a), the back side in FIG. 10 (b), and the front side in FIG. 10 ( In any of the states of c), the position of the fixing groove 42 can be set so that the screw 53 penetrates the base material 62 of the wall. Therefore, in the present embodiment, the door tail side vertical frame 20 can be firmly fixed to the wall even if it is slightly deviated from an appropriate position in the direction perpendicular to the wall.

Next, the door end side vertical frame 18 according to the reference form will be described with reference to FIG.

As shown in FIG. 11A, when the door 93 is closed, the door 93 hits the door stop member 92, and a force is applied to the door stop member 92 on the back side (the side opposite to the side where the door 93 exists). In the door end side vertical frame 18 according to the reference form, the screw 53 is screwed in at the same position as the groove 43 into which the door stop member 92 is fitted, and the screwing position serves as a fulcrum, and the above-mentioned force is applied to the door end side vertical It acts to pull the front side of the frame 18 away from the wall. Therefore, as shown in FIG. 11B, the front side of the door end side vertical frame 18 is pulled away from the wall and floats, causing a problem that it interferes with the door 93. However, in the door end side vertical frame 10 according to the present embodiment, as shown in FIG. 4, the screwing position of the screw 53 is separated from the door stop member 92 and exists on the front side, so that such a problem occurs. Absent.
