Description

[Detailed description of the invention] This invention is an entrance door in which a front decorative board is attached to the front side of a door frame consisting of left and right vertical stiles and upper and lower horizontal stiles, and a back decorative board is attached to the inside of the door frame. The present invention relates to an insertion device for a back decorative board which can be easily inserted and removed without any troublesome attachment and assembly using screws, etc., and which has a good appearance.

This kind of conventional entrance door has a front decorative board with an uneven pattern etched on the surface attached to the front side of the door frame, and a frame attached to the periphery of the back decorative board is attached to the back side by welding or screws. Many of them are screwed together. However, screwing the frame around the back decorative panel to the door frame with screws required a great deal of work as each screw hole had to be drilled in advance and then screwed in, and the heads of each screw were exposed, making it difficult to see the appearance. This also makes it unsightly and requires a covering plate to cover it up.Also, when the glass plate attached to the inner surface of the window hole of the decorative panel is damaged, it is necessary to replace it by attaching and removing screws one by one. There was a disadvantage that required a tremendous amount of effort.

However, there are conventional decorative panels that can be assembled and disassembled into the door frame, but conventional panels require troublesome work to fit together various parts when reassembling after disassembly, so the decorative panels can also be easily attached and removed. I was at a disadvantage.

The present invention eliminates all of the conventional disadvantages mentioned above and allows the rear decorative panel to be easily inserted and removed from the door frame, thereby efficiently assembling this type of entrance door and making it easier to assemble the glass panel attached to the decorative panel. It also makes it easy to replace.

That is, as shown in the drawings, the left and right edges of the facing panel 5 are screwed to the outer surfaces of the left and right stiles 2 of the door frame 1 with screws 6, and the inner walls 2b of the left and right stiles are screwed together with screws 6.
In this case, the base pieces 10b of each of the fixing metal fittings 10, each having a protruding side arc-shaped elastic piece M on the outer surface thereof, are screwed together with screws 11, and the outer surfaces of the elastic pieces M of these fixing metal fittings are connected to the outer surfaces of each of the left and right vertical frames 2. The left and right outer edges 9a and inner edges 9b of the picture frame 9 attached to the periphery of the back decorative board 8 are freely inserted and removed between the inner surfaces of the protruding pieces 2a provided inwardly projecting from the outer surface and the outer surfaces of the inner edges 2c of the left and right vertical frames 2. The upper and lower horizontal frames 3 are interposed between the upper and lower ends of the left vertical frame 2, respectively, and both ends of the horizontal frames 3 are screwed to the upper and lower ends of the left and right vertical frames, respectively. In the drawing, 4 indicates a middle horizontal stile interposed between the left and right vertical stile 2, and N indicates a curved piece formed at the inner end of each projecting piece 2a.

The present case has been constructed as described above, so when assembling the present entrance door, first screw the left and right edges of the decorative board 5 onto the outer surfaces of the left and right vertical frames 2 with screws 6, and then screw each of the left and right vertical frames 2. A middle horizontal stile 4 is interposed in the middle, and both ends thereof are fixed to the left and right stile 2.Inner surfaces of protrusions 2a protruding from above and below the rear left and right stile 2 to the inside of these stile 2 and respective fixing metal fittings. After inserting the left and right outer edges 9a of the frame 9 attached to the periphery of each of the upper and lower back decorative panels 8 between the outer surfaces of the 10 elastic pieces M, between the upper and lower ends of the left and right vertical frames 2, The main entrance door is completed by screwing each end of each upper and lower horizontal stile 3 to each vertical stile 2.

As described above, in this case, between the inner surface of the protruding piece protruding from the inside of each of the left and right vertical frames of the door frame with the decorative board attached to the outer surface, and the outer surface of the elastic piece of the fixing metal fitting,
By simply inserting the outer edge of the frame of the back decorative board, the back decorative board will be tightly clamped, and by attaching horizontal frames to the top and bottom ends of the left and right vertical stiles, the work will be completed. It eliminates the troublesome work of attaching and detaching, assembling and disassembling, and can be completed easily and efficiently.It also saves on screws and other mounting parts, allowing you to obtain a good-looking entrance door at a low cost. If the glass plate attached to the inner surface of the window hole is damaged, it can be replaced simply by removing the side stile and then inserting and removing the back decorative panel, so it is very easy to repair and replace. This is an extremely advantageous idea for a prefabricated entrance door.
