Description

[Detailed description of the invention] Industrial application field This invention relates to entrance doors made of metal materials such as aluminum building materials, and is particularly applicable to decorative entrance doors that use decorative panels etc. to give elegance, solidity, etc. do.

Prior Art There are two types of conventional decorative entrance doors, for example:

One type consists of a grid of vertical and horizontal crossbars, the outer periphery is framed by upper and lower horizontal stiles, and left and right vertical stiles, and the panels are secured with screws from the front and back sides, making installation of the panels relatively easy. Although it is simple, it requires panels on the front and back sides, and because it is attached from the front, it is difficult to fit and lacks beauty and solidity.

Another type is to assemble vertical and horizontal bars in a lattice pattern, fit a panel with a decorative frame around the periphery, fix top and bottom, left and right picture frames to the outer periphery, and then attach top and bottom frames to the outer periphery of these frames. , some have left and right frames attached. However, this format has many parts, and during assembly, the panel must be fixed while the top and bottom, left and right frames must be attached, making the assembly process complicated.

Purpose of the invention This invention was designed specifically for an entrance door with an arcuate upper part, which is highly decorative and easy to assemble.
The purpose is to provide a strong entrance door.

Structure of the invention The entrance door of this invention consists of a plurality of panels, vertical and horizontal middle bars, a surrounding frame, a lower frame, a surrounding stile, and a lower stile, and the upper part of the door is formed in an arc shape.

The panel is made of a glass plate or metal such as decorative aluminum casting, and is framed by a decorative frame with a fitting convex portion on the outer periphery. The vertical and horizontal bars are arranged in a lattice or ladder shape, intersecting each other, to separate the panels. The material used is aluminum extrusion.

The peripheral frame and the lower frame are members that surround the panel from the outer periphery, and the lower frame connects both lower ends of the peripheral frame, which has an arcuate upper part.

These vertical middle bars, horizontal middle bars, surrounding picture frame, and lower picture frame are provided with fitting recesses into which the fitting convex parts of the decorative picture frame of the panel are fitted, so that they can be fitted to each other.In particular, regarding the surrounding picture frame, By slightly pushing open the upper arcuate portion, the member can be fitted using its elasticity.

In addition, a lower stile is attached to the outer periphery of the frame consisting of the surrounding frame and the lower frame, which connects the surrounding stile with an arcuate upper part and both lower ends of the surrounding stile. This is done by utilizing a fitting protrusion provided on the outer periphery of the lower frame and a fitting recess provided on the inner periphery of the surrounding stile and the lower stile.

Example Figure 1 shows how the entrance door A of this invention is attached to the door frame B. Door A, door frame B
Both have an arcuate upper portion and are designed to open and close around a hinge 8.

6 and 7 are a cross-sectional view and a vertical cross-sectional view, respectively, of this door A. The peripheries of the plurality of panels 1 are each framed by a decorative frame 2 via a gasket, etc., and each panel 1 has a vertical sectional view. Crosspiece 3a, horizontal middle crosspiece 3b
It is framed by a surrounding frame 4a and a lower frame 4b. Also, the surrounding picture frame 4a and the lower picture frame 4b
A surrounding stile 5a and a lower stile 5b are attached to the outer periphery of the frame. The decorative picture frame 2 has a fitting convex part 6a formed on the outer circumferential position opposite to the opening where the panel 1 is attached. Fitting convex portion 6a
A lip groove-shaped fitting recess 6b into which the two parts can be fitted is formed so that the two parts can be fitted into each other. Note that the shapes of the fitting protrusion 6a and the fitting recess 6b are not limited to this. In Fig. 7, 9b is the surrounding frame 4a.
This is a screw hole for screwing the horizontal middle crosspiece 3b. In addition, on the outer peripheral surfaces of the peripheral frame 4a and the lower frame 4b, opposing protrusion-like fitting protrusions 7a are formed.
They are fitted into fitting recesses 7b provided on the inner peripheral surfaces of the surrounding frame 5a and the lower frame 5b, respectively. The shapes of the fitting protrusion 7a and the fitting recess 7b are not limited to these, either.

FIGS. 2 to 5 show the assembly procedure of this door A. First, the horizontal middle bars 3a and the vertical middle bars 3b are connected to form a frame. Next, the fitting protrusions 6a of the decorative frame 2 attached around the panel 1 are fitted into the fitting recesses 6b of the vertical middle crosspiece 3a and the horizontal middle crosspiece 3b.
I'm going to install it. As shown in FIG. 3, the upper arcuate portion of the surrounding frame 4a is expanded and placed over the panel 1 from above. At this time, the peripheral frame 4a tends to return to its original state due to the elasticity of the members, so the fitting convex portion 6a and the fitting recess 9b are successively fitted. The lower frame 4b is fitted to the lower end, connected to both lower ends of the surrounding frame 4a, and fastened with screws 9a as shown in FIG. 4, thereby completing the assembly of the panel portion of the door A. Finally, as shown in Fig. 5, slide the outer frame 5a from above, and slide the lower frame 5b from below.
The above-mentioned fitting protrusion 7a and fitting recess 7 are fitted together.
Use b to fit and fix.

FIG. 8 shows how the door A of this invention is installed in the opening of the frame, and is installed in a door frame B consisting of a peripheral frame 10a with an arcuate upper part and a lower frame 10b. In the figure, 10a' is a frame portion of the surrounding frame that protrudes toward the outdoor side, 11a and 11b are airtight materials,
12a and 12b are stainless steel covers, 13 is an anchor, 14 is a screw, 15 is a beam, and 16 is an interior material.

Effects of the Idea: A peripheral frame with an arcuate upper part is used, and the elasticity of this arcuate portion can be used to frame the panel, making assembly very easy. In other words, the surrounding frame can be pushed open and covered from the outer periphery of the panel attached to the middle crosspiece, and then the frame can be easily formed using the fitting convex part of the decorative frame of the panel and the fitting recess of the surrounding frame, etc. . Additionally, the surrounding frames are attached with the panel portions framed, making it easy to assemble. In addition, since the parts fit into each other, they have excellent strength and integrity, and since there are no gaps, they look good and are easy to wipe clean.
