Description

[Detailed Description of the Invention] A. Field of Industrial Application This invention relates to a mounting structure for an indoor door unit that is primarily attached to a flashing panel.

B. Conventional technology and its problems In conventional doors, the door frame is fixed directly to the edge of the wall, and the periphery of the door is shaved to fit the frame, so that the gap between the periphery of the door and the frame is uniform. After adjusting the fittings to create a gap, the door was fixed to the frame using hinges. For this reason, it takes considerable time to adjust and install the door fittings, and advanced technology is required to create uniform gaps around the periphery of the door body.
There was a drawback that not everyone could easily construct it.

This is because the upper and lower edges of the frame to which the frame is fixed are not necessarily perfectly vertical with an error of less than 1 mm, and the frame that is directly fixed to this is not necessarily perfectly vertical. However, the outside shape of the door had to be adjusted accordingly.

By the way, a method of constructing a door frame in which an anchor, which is a mounting piece, is fixed to the outer periphery of the door frame has been developed (Japanese Patent Laid-Open Publication No. 72944/1983).

In this door frame, a mounting piece, which is an anchor, is fixed only to the center of the door frame, and this is attached to a reinforcing member corresponding to the rim of the present application via screws.

With this structure, since the mounting piece does not pinch both sides of the rim, it can be easily fitted into the mounting opening of the door. However, a single plate-shaped mounting piece cannot firmly fix the door frame. For this reason, it is necessary to use a thick and sturdy plate material for the mounting piece to make it considerably strong. Thick and strong board materials cannot be deformed to adjust the mounting position during installation, making installation time-consuming.

Furthermore, with this structure, the door frame is fixed to the body rim using screws, but these screws tend to loosen due to strong impacts when opening and closing the door. There was a drawback that it could not be fixed and the door could not be opened and closed smoothly over time.

Furthermore, the door frame is provided with a gap for inserting the outer peripheral edge of a surface plate such as a wall board, but this gap cannot be changed, and surface plates of different thicknesses cannot be inserted without a gap. In other words, if a wall board that is thinner than specified is inserted into the gap in the door frame,
There will be a gap between it and the door frame, and on the other hand, wall boards that are too thick cannot be fitted. For this reason, the thickness of the wall board used in combination with the door frame is specified, and boards with different thicknesses cannot be used.

However, the problem is that even if the wall boards are the same standard product with a fixed thickness, there is some variation in the thickness.

Furthermore, a mounting bracket for fixing a door frame to a pillar by bending a mounting piece has also been developed (Japanese Utility Model Publication No. 53-62051).

Furthermore, a structure in which the frame is fixed to a column using two mounting pieces facing each other has also been proposed (Jikkosho
43-14360).

However, these conventional frames do not have a structure in which the periphery of the surface plate of wall material etc. is fitted into the frame, but the outer periphery of the surface material is in contact with the outer surface of the frame or along the outer surface of the frame. The disadvantage was that it took a lot of time to process the edges of the surface plate, and it required a highly skilled and highly skilled person to finish the work, and it was impossible to achieve a clean finish unless extremely careful finishing was done.

Furthermore, a steel frame for wooden doors has been developed in which a gap is provided between the door frame and the door frame to which the door frame is fixed, into which the periphery of the surface plate is inserted (Jikkosho).
Publication No. 48-45225).

However, since the door frame with this structure penetrates from the inside to the outside, which is the contact surface of the door, and fastens the door frame with screws, the screws tend to loosen due to the strong vibrations that occur repeatedly each time the door is opened and closed, resulting in a long door. There was a drawback that the period could not be fixed reliably.

In the mounting structure of a door, it is extremely important that the door frame be strong and securely fixed to the building frame. In particular, we do our best to prevent the door from opening and closing smoothly due to repeated opening and closing and strong impact when the door is closed, which may cause rattling in the mounting structure, or may cause the door to hit the frame and become misaligned. must be prevented.

However, the mounting structure shown in the above publication is
There was no means to prevent the screws and nails used to fix the door frame from slipping out, and there was a drawback that it was impossible to eliminate the door's misalignment and difficulty in closing over time.

This invention aims to eliminate these conventional shortcomings,
To provide an indoor door unit in which a frame body to which a door body has been attached in advance is fixed to the wall via a receiving piece protruding from the outer periphery of the frame body, instead of directly fixed to the furring strip of a wall as in the conventional method, and the outside of the receiving piece is covered with a surface plate of the wall, thereby enabling the frame body to be attached very simply and quickly, while accurately aligning the gap between the outer periphery of the door body and the frame body when attached, and further enabling the attachment part to the wall and the edge of the surface plate to be neatly attached without any gaps without much effort.

Another important purpose of this invention is that by bending the mounting pieces during installation, the framed frame can be easily and easily fixed to the rim, and the mounting position of the frame can be easily changed. To provide an indoor door unit which is adjustable and can be easily attached to body edges having slightly different widths.

Furthermore, another important purpose of this invention is that the nail material that fixes the door frame is pressed and fixed by the surface plate, so that the door frame can be securely fixed for a long period of time without shifting, and the door can be opened and closed smoothly for a long time. To provide a mounting structure for an indoor door unit.

C. Means to solve conventional problems The mounting structure of the indoor door unit is the door body 1.
The door body 1 is made up of a frame 2 attached via a hinge on one side so as to have a predetermined interval around the outer periphery of the door body 1, and a rim 6 serving as a core material of the wall.

The frame body 2 is formed wider than the thickness of the wall to which it is attached, and a mounting piece 5 is fixed thereto.

This mounting piece 5 is a metal piece that has a length that protrudes from the outer peripheral surface of the frame 2 by a required length, and is itself bendable, and has a required spacing on the outer periphery of the frame 2. A plurality of mounting pieces 5 are fixed independently from each other with a distance of
are fixed to the frame 2 at intervals approximately equal to the width of the frame 2.

Further, on both sides of the frame body 2, surface plate push pieces 9 are provided so as to be located outside the mounting pieces 5 and extend to the outer periphery of the frame body 2.

A fitting gap 8 is formed between the surface plate pusher piece 9 and the mounting piece 5, into which the peripheral edge of the face plate 7 fixed to the surface of the wall can be fitted, and the mounting piece 5 penetrates the peg material. The outer edge 6 is clamped and fixed from both sides to the back surface of the surface plate 7 of the wall through the screws 10, and the peripheral edge of the surface plate 7 is fitted into the fitting gap 8 with the peg material 10 being pressed against the outer edge 6. It has been fixed.

D Construction method The method for installing a door unit with this structure is to bend the mounting piece 5 on one side outward, fit the frame 2 into the pre-fixed rim 6, and then bend the door unit as shown by the chain line in Fig. 2. Attach the mounting piece 5 that was attached to the second
As shown by the solid line in the figure, fix the mounting piece 5 to the rim 6 with pegs 10 along both sides of the rim 6 at a position where there is a certain gap between the frame 2 and the door body 1. The end edge of the surface plate 7 is inserted into the fitting gap 8, and the peg material 10 is pressed against the furring edge 6 on the inner surface and fixed.

E. Preferred Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

The mounting structure of the indoor door unit shown in FIG. 1 and FIG.
A frame body 2 arranged with a constant gap is fixed to a trunk rim 6.

The frame body 2 is made by bending a surface-treated metal plate, and the overall shape is formed in a U-shape.The door body 1 is attached to one side via a flag hinge 3, and the cross-sectional shape is , as shown in Figure 2, is bent into a U-shape that is wider than the thickness of the wall to which it is attached, and is located on the inside and is somewhat unevenly distributed on one side to form a protrusion 4 that serves as a doorstop. .

A mounting piece 5 is fixed to protrude outside the frame 2, and the mounting piece 5 is a bendable metal plate and has a length that projects from the frame 2 by, for example, 10 mm to 15 cm,
One side is welded to the frame 2.

The mounting pieces 5 are arranged facing each other so that they are fixed to the wall rim 6 via pegs 10 such as nails or screws, and the pair of mounting pieces 5 are spaced apart from each other. are fixed to the frame 2 at a distance equal to the width of the furring 6.

As shown in FIG. 2, the head of the nail material 10 that penetrates the mounting piece 5 and fixes it to the rim 6 is pressed toward the rim 6 by the surface plate 7 pushed into the fitting gap 8. be done.

Furthermore, as shown in FIG. 1, a plurality of mounting pieces 5 are fixed to the frame 2 at regular intervals.

On the other hand, on both sides of the frame body 2, surface plate push pieces 9 are provided which are located outside the mounting piece 5 and extend to the outer periphery of the frame body 2, and between the face plate push piece 9 and the mounting piece 5. To,
A fitting gap 8 into which the outer peripheral edge of the surface plate 7 can fit is formed.

F. Effect The indoor door unit of the invention can be simply and easily finished neatly by fitting the outer periphery of the surface plate into the frame. It can be fixed without any gaps, and also,
The door can be firmly fixed for a long period of time without shifting, allowing the door to open and close smoothly for an extended period of time, which is an important feature for a frame.

This feature is that the mounting pieces 5 are fixed to the outer periphery of the frame 2 at intervals approximately equal to the width of the furring 6.

The mounting piece 5 is a bendable metal piece.

On both sides of the frame 2, surface plate push pieces 9 are provided located further outside the mounting pieces 5, and the outer peripheral edge of the face plate 7 can be fitted between the face plate push pieces 9 and the mounting pieces 5. A gap must be provided.

The mounting piece 5 is fixed to the rim by a peg 10 passing through it, and the tack 10 is pressed against the rim by a surface plate 7 inserted into the fitting gap and is prevented from slipping out.

This is realized by a configuration unique to the present application.

That is, when the peripheral edge of the surface plate 7 that is thinner than the specification is inserted into the fitting gap 8, a gap appears between the surface plate 7 and the surface plate push piece, but in this case, the mounting piece 5 is a bendable metal piece. Therefore, it may be bent into a corrugated shape or partially convex to increase its substantial thickness and fixed to the rim 6, or alternatively, another surface may be attached to the surface of the rim 6. By pinching the thin plate material between the mounting pieces 5 from both sides, the fitting gap 8 can be substantially narrowed, and the thin surface plate 7 can be fitted without any gap. Although it is not possible to fit a surface plate that is too thick, the door unit of this application allows a thin surface plate to be inserted without any gaps.The fitting gap can be set wide so that a somewhat thicker surface plate can be inserted, so in reality, the thickness differs considerably. The surface plate can be securely fixed without any gaps. Therefore, not only can standard surface plates with varying thicknesses be fixed easily and without any gaps, but also a wide variety of surface plates with different thicknesses can be used, and the frame can be beautifully finished. It is possible to realize extremely important features for

Moreover, the mounting structure of the door unit according to this invention is such that the frame 2 is not directly fixed to the rim 6;
It is fixed to the wall via the mounting piece 5 that protrudes outward from this, and there is a fitting gap between the surface of the mounting piece 5 and the surface plate pressing plate 9 into which the outer peripheral edge of the surface plate 7 is fitted. 8 is formed, and furthermore, the distance between both sides of the mounting piece 5 is formed to be approximately equal to the width of the flange 6, and furthermore, the door body 1 is attached to the frame 2 via a hinge. Because it is fixed,
After fitting the frame 2 into the mounting opening of the wall, the mounting piece 5 is fixed to the wall rim 6 of the wall at a position where the gap between the frame 2 and the door body 1 is uniform. It can be easily and quickly installed, and in addition, the frame body 2 can be fixed in a position where the gap is evened out, instead of adjusting the gap around the door by adjusting the external shape of the fittings, so it is not necessary to use advanced technology. It can be installed by aligning this gap uniformly without requiring
It can be covered with the outer surface plate 7 of the mounting piece 5, and the outer peripheral edge of the surface plate 7 can be inserted into the fitting gap 8 of the frame 2.
Since it can be inserted into the frame body 2, it has many advantages such as easy and clean end treatment of the surface plate 7 and the frame body 2.

Furthermore, in the indoor door unit of this invention, the mounting piece 5 fixed to the outer periphery of the frame 2 is a bendable metal piece, so when the frame 2 is attached to the body rim 6, it must be opened. It can be fitted inside the furring 6. For this reason, even though the mounting pieces 5 can be fixed in a state in which the furring rim 6 is sandwiched, the mounting pieces 5 can be fixed to both sides of the furring rim 6 while the frame 2 remains assembled.
Therefore, the frame body 2 can be easily and easily attached, and the frame body 2 can be firmly fixed to the furring 6.

Furthermore, a noteworthy feature of the mounting structure of the door unit of this invention is that it can be firmly fixed in place even when the door is opened and closed repeatedly over a long period of time, and even when the door is closed and receives a strong impact, it can be firmly fixed in place. To effectively prevent the door from becoming difficult to open and close due to misalignment of the frame. This feature is that the bendable mounting piece is also used to adjust the fitting gap of the surface plate, and the peg material is fixed to the frame by passing through the mounting piece, and the peg material is inserted into the fitting gap. This is realized by a configuration unique to the invention of the present invention, in which the top plate is pressed against the barrel edge.

In other words, even if a face plate whose edges are inserted and fixed into the fitting gap is repeatedly subjected to strong impacts, the nails will not come out and come off the body rim, unlike a face plate whose peripheral edges are nailed. The face plate prevents the peg material from slipping out. Therefore, the mounting piece does not come off the body rim no matter how strong the impact it receives when opening and closing the door, and is firmly fixed in place for a long period of time, achieving excellent efficiency in that the door can be opened and closed smoothly forever.

Furthermore, since the mounting piece 5 can be slightly deformed when fixed, the mounting position of the frame 2 can be adjusted, and
It is possible to realize the feature that it can be easily fixed to body edges 6 having slightly different widths.

Furthermore, since a plurality of mounting pieces 5 are fixed independently from each other at a required interval,
It can be easily bent with little force, making it extremely convenient to handle.
