Description

[Detailed description of the invention] Industrial application field This invention allows a lower frame having at least one different structure, shape, or material to be attached to the waste frame part of a basic door frame formed in a square shape. Regarding door frames.

Conventional technology Door frames can be roughly divided into (1) single-open type, (2) sleeve type,
and (3) parent-child type, and (2) sleeve type is further divided into two types depending on whether the sleeve part is on the left or right side of the door frame. Furthermore, the types of door frames differ depending on the structure and material of the lower frame.

For this reason, not only does the number of types to be stored as stock in the rectangular door frame significantly increase, but also the storage thereof requires a large amount of space, which is disadvantageous.

Purpose This invention was made in view of the above circumstances, and is to provide a door frame that can easily create a door frame with a different bottom frame structure, shape, or material from the same basic door frame. It is in.

Structure This invention forms the free frame portion of the basic door frame into a square shape or a modified shape, and adds a structure to the free frame portion.
This is a door frame with a lower frame of a different shape or material.

Embodiments This invention will be described in detail based on the embodiments shown in FIGS. 1 to 6. Note that this invention is not limited to this.

Figures 1 and 2 show a first embodiment of this invention, in which a basic door frame 1, which is usually made of iron, is made up of left and right vertical frames 2, an upper frame 3, and a waste frame 4. It is shaped like a square. The waste frame 4 has a square shape and is fixed to the lower end of the vertical frame 2 by welding 6 or the like so that the portion facing the lower end surface 5a of the door 5 becomes the upper plane 4a. The frame 4 may have a square shape instead of a square shape.

A lower frame 7 made of iron or stainless steel, in which a groove 7a into which the airtight gasket 11 is fitted, is formed in the waste frame 4, and a portion facing the lower end surface 5a of the door 5 is brought into close contact with the upper plane 4a of the waste frame 4. installed to do so. The lower frame 7 has a shape that is bent vertically downward along the outer edge of the upper plane 4a of the waste frame 4, and then bent again at right angles to the side of the waste frame 4. The part of the inner vertical wall surface 7c that is in close contact with the vertical wall 4b is fixed to the frame 4 by means of rivets 8.
installed on.

To install the lower frame 7, as shown by the two-dot chain line in FIG. The wall surface 7c is lowered vertically and overlapped with the waste frame 4, and with the lower frame 7 in close contact with the upper plane 4a of the waste frame 4 and the fitting part vertical wall 4b, the two are joined by rivets 8. do. The door frame 1 to which the lower frame is fixed is installed by burying an inverted L-shaped mounting member 9 projecting downward from the inner surface of the central vertical wall 4c of the waste frame 4 in mortar 10 on the floor side.
Numeral 11 is a door stop packing installed in the groove part 7a of the lower frame 7, which maintains airtightness between the door frame 1 to which the lower frame is fixed and the door 5, and also reduces the impact when closing the door 5.

When the door frame is configured in this way, by attaching a lower frame 7 of different structure, shape, or material, for example, made of iron or stainless steel, to the waste frame 4 of the basic door frame 1, Basic door frame 1
Since the door frames 1 can be easily varied, the types of basic door frames 1 to be stocked and the space required for storing them can be significantly reduced.
When a stainless steel material that does not require painting is used for the lower frame 7, there is no need to worry about the paint peeling off, and strong resistance to corrosion can be provided.

3 to 6 show different embodiments in which the lower frame 7 fixed to the waste frame 4A is made of iron or stainless steel.

Figure 3 shows the airtight door frame shown in Figure 2.
The shape of the waste frame 4A is changed to a square shape with a downward vertical wall surface 4d formed at the outer end of the square shape, and an inclined surface 7d is formed at the upper end bending part of the inner vertical wall surface 7c of the lower frame 7.
By forming , unlike the case in Figure 2,
This is a case where the upper surface of the mortar 10 on the floor surface is made to have approximately the same height on the indoor side and the outside of the lower frame 7.

FIG. 4 shows a case where a bottom frame 7 of a structure suitable for the basic door frame 1 is attached to a basic door frame 1 equipped with a waste frame 4A that does not require very strong airtightness with the door 5, and the upper surface of the mortar 10 is attached to the bottom frame. The heights are different inside and outside of 7.

In FIG. 5, an inclined surface 7d is formed at the upper bent portion of the inner vertical wall surface 7c of the lower frame 7 shown in FIG. 4, as in the case of FIG. This is a case in which the top surfaces of the devices 10 and 10 are made to have approximately the same height.

FIG. 6 shows that, unlike in each of the above-mentioned embodiments, the lower frame 7 is fitted so as to be in close contact with the upper plane 4a of the sacrificial frame 4A facing the lower end surface 5a of the door 5, and
When the door 5 is fixed to the central vertical wall 4c with a rivet 8, the door 5 is held in a predetermined position by contacting the doorstop rubber 12 attached to the vertical frame 2, and the mortar 1
0 has the same height on the indoor side and outside of the lower frame 7.

Even when the door frame is configured as shown in FIGS. 3 to 6, the same effects as described for the first embodiment can be obtained. It goes without saying that the square frame 4A shown in FIGS. 3 to 6 may be changed to the square frame 4 shown in FIG.

Effects This invention forms the free frame portion of the basic door frame into a square shape or a modified shape, and attaches a lower frame that differs in at least one of the structure, shape, or material to the free frame portion. Because of this, it is possible to create many different types of door frames from the same basic door frame with a waste frame.

For this reason, it is only necessary to stock the basic door frame with the same waste frame and the bottom frame of different types, which not only makes it possible to mass-produce basic door frames and reduce costs, but also allows the basic door frame and the type of bottom frame to be The space required for storing different bottom frames can be reduced, resulting in significant cost savings.

Further, when the material of the lower frame is made of stainless steel, for example, there is no need to worry about the paint peeling off, and strong resistance to corrosion can be provided.
