DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel unit in which a panel such as a glass plate or a panel plate is mounted on a frame such as a decorative panel unit mounted on a door frame.

[0002]

2. Description of the Related Art As a door for an entrance, a door is known in which a plurality of decorative panel units are attached to a door frame so as to improve the appearance and design.

The above-described decorative panel unit is known in which a panel such as a glass plate or a panel plate is attached to a frame body in which an upper frame material, a lower frame material, and left and right vertical frame materials are assembled in a rectangular frame. .

In order to form the above-mentioned frame members into a rectangular frame, each frame member has a sectional shape having a hollow portion and a concave portion for mounting a panel, and both end surfaces of each frame member are cut at an angle of 45 degrees. After cutting, an L-shaped corner block is pressed into the hollow portion of each frame material from the cut end surface, and the cut end surface of each frame material is brought into contact. And what fixes a frame material and a corner block by means, such as screwing or caulking, is generally known.

In the above-described rectangular frame structure, corner blocks are arranged at all of the corners (four corners).
Since a large number of screws for fixing the corner block and the frame material are required, the number of parts is high and the price of the parts is high, so that not only is the entire panel unit expensive, but also a plurality of (four) corner block press-fitting operations. However, since the work of screwing a large number of screws or the work of caulking the corner block and the hollow profile largely depends on humans, the work requires labor and time, resulting in poor production efficiency.

Further, as a structure for forming a frame material into a square frame,
JP-A-58-73680 and JP-A-61-519.
The one disclosed in Japanese Unexamined Patent Publication No. 2 (KOKAI) is known. They are,
The frame member is fixed to a jig in a state where the cut end surfaces of the 45 ° are in contact with each other, and a thermoplastic resin is injected into the hollow portion from an injection port formed on the surface of the frame material. After this, the thermoplastic resin
It hardens into a corner block and connects each hollow profile.

[0007] Also in this structure, it is necessary to dispose the corner blocks at all the corner portions (four), which does not lead to a reduction in the cost of parts. Further, it is necessary to previously form an injection port for injecting the thermoplastic resin into the surface of the frame material, which leads to an increase in the number of working steps. Furthermore, it is difficult to fix the 45-degree cut end face of each frame material to the jig without displacement, which requires labor and time for the operation, resulting in poor operation efficiency.

In view of the above, as a frame for reducing the number of corner blocks and screws, reducing the cost of parts, simplifying the work process, and improving the production efficiency, Japanese Patent Application Laid-Open No. Sho 60-23431 is disclosed. The one disclosed in Japanese Patent Application Publication No. JP-A-2006-26095 is known. This product is designed to have 45
And V-grooves are formed in the profile.
Then, the frame is bent at the V-groove portion, and the both end surfaces are brought into contact with each other and joined to form a frame. At the joint,
An L-shaped connecting plate is arranged and temporarily fixed, a foamed resin is injected into the temporarily fixed joint, a foamed resin layer is formed, and the shape member and the connecting plate are integrally fixed.

[0009]

The above-mentioned Japanese Patent Application Laid-Open No. Sho 60-2
The frame disclosed in Japanese Patent No. 3431 has a recess inside the connecting plate, and a panel can be attached to the recess to form a panel unit.

However, a corner portion (a joint portion where both end faces of the V-groove portion are in contact) in a portion where the concave portion is formed.
There is a gap in In other words, it is difficult to form a V-groove in a profile so that both end surfaces of the V-groove portion are in close contact with each other in terms of processing accuracy, and a slight gap is formed in a corner portion, so that a concave portion is formed. There is a gap at the corner of the part.

For this reason, in the case of a panel unit for decoration of a door for an entrance, light in the room leaks out of the gap through the gap, and sunlight outside the room enters the room.
So-called light leakage occurs, which is not preferable as an entrance door.

Therefore, the present invention solves the above-mentioned problems, and
Parts cost is low, work is simplified and productivity is high.
Moreover, an object of the present invention is to provide a panel unit in which light leakage does not occur.

[0013]

According to a first aspect of the present invention, there is provided a profile having a concave portion for mounting a panel on one side of a vertical plate, another vertical plate, and an end connecting plate on a side opposite to the end connecting plate. A V-groove formed at intervals in the longitudinal direction, bent at the V-groove portion to abut the cut end faces of the V-groove, and having a plurality of corner portions connecting both longitudinal end portions; was swallowed recess for panel mounting body to the panel unit in the mounting panel, the the corner portion butt cut end face mutual V groove of the profile, after stable foam resin a viscous
Is a panel unit characterized by being continuously filled with a flexible foamed melt from an end connecting plate to an opening edge of a concave portion. According to a second aspect of the present invention, the panel of the first aspect is provided in a door frame in which left and right vertical frames, an upper frame, and a lower frame are assembled in a rectangular frame.
This is the door to which the unit is attached .

[0014]

According to the first aspect of the present invention, since the shape is bent at the V-groove portion to form a corner, no corner block and screws are required, so that the cost of parts is reduced and the work of assembling the corner block and the screw is performed. And work efficiency is improved. Further , even if there is a gap at the abutting portion between the cut end surfaces of the V-shaped grooves of the profile, light leakage from the gap does not occur because the foamed melt is continuous from the end connecting plate to the opening edge of the concave portion. In addition, since foamed melt has viscosity,
Prevents parts from flowing and allows precise filling at defined locations
Wear. Moreover, the foamed melt is flexible even after it is stable
From the above, the material filled with the foamed melt
Can be easily folded. According to the second invention, since the panel unit mounted in the door frame does not leak light,
It is a door that does not allow indoor light to leak out of the room or outside sunlight to enter the room.

[0015]
