Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated entrance door having a lighting part.

[0002]

2. Description of the Related Art There is known an insulated entrance door having a lighting part in which an opening is formed in a heat insulating door body and glass is attached to the opening with a picture frame.

[0003]

According to the above-mentioned heat-insulated entrance door, the provision of the daylighting section enables the daylighting inside the entrance and the design point. When the number is increased, the width of the opening is reduced, the frame is provided, and the thickness of the heat-insulating door body (inside / outside method) is large, so it is difficult for light from outside to enter the room. Has the problem of becoming dark.

Therefore, an object of the present invention is to provide an insulated door capable of solving the above-mentioned problems.

[0005]

SUMMARY OF THE INVENTION According to the present invention, an opening 10 is formed in a heat insulating door body 1, and a glass 40 is attached to the opening 10 with an indoor side frame and an outdoor side frame to form a lighting section. In the door, the room-side vertical frame 20 is formed of a mounting portion 21 facing the finding direction, and a glass pressing portion 22 that is inclined from the inside of the fitting portion 21 in the finding direction to the outside in the viewing direction. The outer vertical frame 30 is formed of a mounting portion 31 facing the finding direction, and a connecting portion 32 facing the interior side of the prospective direction from the outer side of the mounting portion 31 in the finding direction,
The mounting portion 21 of the indoor side vertical frame 20 and the outdoor side vertical frame 30
The connecting portion 32 is connected by screws, and the vertical edge portion of the glass 40 and the heat-insulating door body 1 are sandwiched between the mounting portions 21 and 31 so that the glass 40 is attached to the opening 10 in the expected direction toward the outdoor side. Glass holding part 22 in vertical frame 20
A heat-insulated entrance door characterized in that a space between the glass doors is gradually increased from a position closer to the glass 40 toward the room.

[0006]

According to the present invention, outdoor light entering from the outdoor opening 2a of the daylighting section 2 is diffused into the room along the inclined glass holding portion 22 of the indoor side vertical frame 20. As a result, even if the width of the daylighting unit 2 is small, the outdoor light can sufficiently enter the room, and the entrance can be brightened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a heat-insulating door body 1 is provided with a plurality of narrow and vertically long light-receiving parts 2 provided with a design property and having a light-receiving part.

The heat-insulating door body 1 has a rectangular frame member 3 around which a channel member 3 is attached, and an upper frame member 4, a lower frame member 5, and a vertical frame member 6 made of a synthetic resin are attached around the channel member 3. 7
And an outdoor surface plate 8, and a heat insulating material 9 such as urethane foam is filled therein.

As shown in FIG. 2, the heat-insulating door body 1 has a narrow and vertically long opening 10 formed therein. This opening 1
0 is oblique so that the opening 10a closer to the room in the prospective direction becomes wider than the opening 10b closer to the outside, and the intermediate opening 10c in the prospective direction becomes wider gradually from the outside toward the room.

The indoor side vertical frame 20 constituting the indoor side frame is hollow and has a mounting portion 21 facing in the direction of finding, and a plate provided integrally on the inner side of the mounting portion 21 in the direction of finding toward the outdoor side. A glass holding portion 22 is provided, and the glass holding portion 22 is slanted such that the indoor side end is located outside in the finding direction from the outdoor end in the expected direction, and a gasket 23 is attached to the outdoor end. It is.

The outdoor side vertical frame 30 constituting the outdoor side frame is formed in a hollow shape with a mounting portion 31 facing in the finding direction, and a plate-like member integrally provided toward the indoor side toward the outside of the mounting portion 31 in the finding direction. A connecting portion 32 is provided. The connecting portion 32 is bent in a substantially rectangular shape along the opening 10, and a concave portion 33 for screwing the screw is formed at the indoor side end portion so as to open toward the indoor side.
A gasket 34 is mounted on the interior side of the mounting portion 31 that is closer to the inside in the finding direction.

A screw 35 is screwed into the concave portion 33 of the connecting portion 32 from the outdoor plate 21a of the mounting portion 21 in the indoor side vertical frame 20, and the connecting portion 32 and the mounting portion 21 are tightened and connected via the spacer member 36, and The outer side of the mounting portion 21 of the inner vertical frame 20 in the finding direction is pressed against the indoor side surface of the insulated door body 1,
The outer portion of the mounting portion 31 of the outdoor frame 30 is pressed against the outdoor surface of the heat-insulating door body while the gasket 2 is pressed.
3 and the gasket 34 sandwich the glass 40 so that the opening 10
The glass 40 is attached to the outside of the viewing direction in FIG.

A through hole 24 is formed in the indoor plate 21b in the mounting portion 21 of the indoor side vertical frame 20, and a screw 35 is screwed into the through hole 24. The through hole 24 is closed by a cap 25.

The glass 40 is a double-layer glass in which an indoor glass 41 and an outdoor glass 42 are connected via a vertical spacer 43 and a horizontal spacer 44. The vertical edge 4 of this glass 40
Oa is in contact with the outside-portion-side portion 32a in the projection direction of the connecting portion 32 via the block 45 so as to prevent rattling in the left-right direction.

As described above, since the found size between the glass pressing portions 22 in the left and right indoor side vertical frames 20 is gradually increased from the position closer to the glass 40 toward the room, the outdoor light entering from the outdoor opening 2a of the daylighting portion 2 is exposed. Is diffused into the room along the inclined glass holding portion 22 of the indoor side vertical frame 20, so that even if the width (found size) of the daylighting portion 2 (effective width of the glass 40) is small, the light outside the room is sufficient in the room. Get into it.

FIG. 3 shows a second embodiment of the present invention.
The glass 41 on the indoor side of the glass 40 is wider than the glass 42 on the outdoor side, and the vertical spacers 43 are slanted.
Is made oblique. The gasket 23 of the indoor side vertical frame 20 is located closer to the outside in the finding direction than the gasket 34 of the outdoor side vertical frame 30.

[0017] Thus, since the indoor side width L ₁ of the lighting unit 2 is wider than the exterior side width L _2, likely more incoming outdoor light in the room.

[0018]

The outdoor light entering from the outdoor opening 2a of the daylighting unit 2 is diffused into the room along the inclined glass holding unit 22 of the indoor vertical frame 20. As a result, even if the width of the daylighting unit 2 is small, the outdoor light can sufficiently enter the room, and the entrance can be brightened.
