JPH10184204A - Sill for door frame of entrance hall - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate the mounting work by providing horizontally parallelly a reinforcing projecting piece and a break-off groove on the rear side of a hanging board made integral to the sill of an entrance door so that the hanging board can be bent and removed by means of a pair of cutting pliers according to the height of the sill. SOLUTION: A hanging board 7 is provided integrally with the front surface of a body 6 whose inlet portion is made lower than the interior of an entrance door 10 to prevent snow from coming into the entrance hall. A plurality of projections 9 are provided on the rear surface of the board 7 and break-off V-grooves 8 are provided horizontally so that an end portion of the board downward of the grooves 8 can be held and cut off by means of a manual tool such as a pair of cutting pliers. And the height of the board 7 can be adjusted according to the difference between the inside and outside levels of the door 10 and when the end portion is removed, the remaining portion thereof can be prevented from being deformed so that the end portion can be easily separated without using a motor-operated tool such as circular saw. Thus the height of the board 7 can be easily adjusted without producing noises.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a lower frame of an entrance door frame.

[0002]

2. Description of the Related Art As a lower frame of an entrance door frame, for example, as shown in Japanese Utility Model Application Laid-Open No. 59-104959, a hanging plate is integrally provided on the outdoor side of a horizontal body of a lower frame. There has been known one in which an exterior material is attached so as to be in contact therewith.

[0003] With this lower frame, the entrance can be made lower than inside the entrance to prevent snow and the like from entering the inside of the entrance.

[0004]

As described above, the height difference between the inside of the entrance and the entrance differs depending on the amount of snow.
Increase the length of the hanging pieces to suit snowy areas,
In an area with little snowfall, the hanging pieces are cut and shortened to simplify the installation of the door frame, and the height difference between the inside of the entrance and the entrance is reduced.

[0005] However, since the hanging piece is cut by an electric tool such as a circular saw, the cutting noise is loud, and it is difficult to cut the hanging piece accurately and to a predetermined length in a straight line.

Accordingly, an object of the present invention is to provide a lower frame of an entrance door frame capable of solving the above-mentioned problems.

[0007]

According to a first aspect of the present invention, there is provided a lower frame body and a hanging plate integrally provided at an outdoor end of the lower frame body. It is a lower frame of an entrance door frame characterized by doing.

According to a second aspect of the present invention, in the first aspect, there is provided a lower frame of the entrance door frame having a projection integrally provided with an upper portion of the breaking groove in the hanging plate.

[0009]

According to the first aspect of the present invention, the lower frame main body is held so as not to move, and the lower end portion of the hanging plate, which is closer to the lower end than the cutting groove, is gripped with a hand tool such as pliers to be bent. Can be cut off from the groove.

[0010] As described above, the hanging plate can be cut straight to a predetermined length and made shorter without generating noise.

According to the second aspect of the present invention, the portion of the hanging plate that is continuous with the upper portion of the groove is increased in rigidity by the protruding piece, and the remaining portion does not deform when the hanging plate is bent and folded. It can be easily and reliably cut off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG.
The lower frame 2 is composed of a lower frame body 6 having a generally hook-shaped upper surface by a heat-insulating member in which an indoor-side member 3 made of extruded aluminum and an outdoor member 4 made of extruded aluminum are connected via a heat-insulating material 5. When,
A hanging plate 7 integrally provided at the outdoor end of the lower frame body 6.
Consists of

A substantially V-shaped folding groove 8 is formed on the interior side surface 7a of the hanging plate 7 near the upper portion and the lower portion. A piece 9 is provided integrally toward the indoor side.

As described above, the lower end portion of the hanging plate 7 at the lower end than the groove 8 is gripped by a hand tool such as pliers, and the lower frame body 6 is supported so as not to move.
By bending the gripped portion toward the outdoor side, it can be easily cut off from the groove 8.

Further, a protruding piece 9 is provided integrally with the upper part of the breaking groove 8, and the rigidity of the upper part of the breaking groove 8 in the hanging plate 7 is increased by the protruding piece 9. Since the remaining portion is not deformed in the outdoor direction at the time of cutting, the cutting is easy and reliable.

[0016] By so because, to be a hanging plate 7 as the length height difference H ₁ between the internal A and inlet B of the entrance as shown in FIG. 2 (a) increases, droop plate 7 In FIG. 2B, if the lower portion is cut off from the lower groove 8 to make the hanging plate 7 have an intermediate length, the height difference H ₂ between the inside A of the entrance and the entrance B as shown in FIG. Is an intermediate value, and if the lower portion of the hanging plate 7 is shortened by cutting off the lower portion from the upper groove 8 in the hanging plate 7, FIG.
Height difference H ₃ between the internal A and inlet B of the entrance becomes most short as shown in FIG.

Therefore, the height difference between the inside A of the entrance and the entrance B can be adjusted to three types with one lower frame, so that the lower frame has excellent versatility and can be used in areas with different snowfall.

A door 10 which is openably and closably attached to the entrance door frame 1 is a heat insulating door.
Is pressed into contact with the airtight material 11 attached to the airtight member 11 to hermetically seal between the door 10 and the lower frame 2.

An indoor stainless steel cover 12 is mounted on the upper surface of the indoor member 3. An outdoor stainless steel cover 13 is attached to the upper surface of the outdoor member 4, and the outdoor stainless cover 13 has a vertical piece 14 and a horizontal piece 15 which are substantially L-shaped. The vertical piece 14 is fixed at the upper and lower middle of the outdoor side vertical plate 3 a of the indoor side member 3 with a screw 17 via a heat insulating plate 16.
The upper end face is pressed against the airtight material 11 and the lower end face is a heat insulating material 5.
Is pressed against. The outdoor end of the horizontal piece 15 has a rectangular shape, and its hook-shaped portion 15 a is engaged with the outdoor member 4.

As described above, the upper surface of the indoor member 3 can be protected by the indoor stainless steel cover 12, the heat insulating material 5 can be protected by the outdoor stainless steel cover 13, and the outdoor vertical plate 3a of the indoor member 3 can be protected. (Outdoor side) airtight material 11
And the heat insulating plate 16 prevents the outside air from touching.

In the above embodiment, the lower frame is made of a heat-insulated shape member. However, the lower frame may be made of an extruded aluminum material in which the indoor member 3 and the outdoor member 4 are integrated. In addition, although the lower frame is used for mounting the door, it is needless to say that the present invention can also be applied to a lower frame in which a shoji is attached in a slipping manner.

[0022]

According to the first aspect of the present invention, the lower frame body is held so as not to move, and the lower part of the hanging plate, which is closer to the lower end than the groove for folding, is gripped and bent by a hand tool such as pliers. It can be cut off from the groove.

As described above, the hanging plate can be cut straight in a predetermined length to reduce the length of the hanging plate without generating noise.

According to the second aspect of the present invention, the portion of the hanging plate that is continuous with the upper part of the groove is increased in rigidity by the protruding piece, and the remaining portion does not deform when the hanging plate is bent and folded. It can be easily and reliably cut off.
