Description

[Detailed Description of the Invention] The present invention relates to a so-called aluminum door made of aluminum material.

In particular, the object of the present invention is to provide an aluminum door that can be assembled without showing mechanically cut end faces or assembly errors when assembling frame materials.

Figure 1A shows an aluminum door in which the present invention is implemented.

1 is a vertical stile, 2 is a horizontal stile, 3 is a horizontal stile, 4 is a vertical stile, and 5 is a decorative panel fitted between these stile and stile.

Each of these members is an extremely high-precision member formed by extrusion molding of aluminum, but since they are made by cutting a long member, processing errors in the cut surfaces are unavoidable.

In conventional assembly, for example, when combining a vertical stile and a horizontal stile,
The joint surfaces were processed with great care and joined together by butting each other.

However, since machining errors are unavoidable, perfect joining of this joint is impossible.

Even if it were possible, it would be disadvantageous in terms of cost.

The present invention aims to provide an aluminum door that can solve the problem of slanting.

This will be explained below with reference to FIG.

Reference numeral 6 denotes a protrusion that is integrally formed inside the vertical stile 1 and whose outer surface is flush with the main body, and protrudes from the main body by about 0.5 to 1 mm.

Therefore, a recess 7 is formed between the protrusions 6, 6.

On the other hand, the thickness of the horizontal stile 2 to be combined with the vertical stile 1 is preformed to exactly the dimension between the protrusions 6, 6.

When assembling, the horizontal stile 2 is fitted into the recess 7 between the protrusions 6, 6, thereby making it easy to assemble.

With the above configuration, the end portion 8 of the horizontal stile 2 is completely covered by the protrusion 6.
, 6, and the edges are hidden, so even if there is a slight machining error, this will not be visible on the outside, allowing for a very beautiful finish.

Furthermore, since the protrusions 6 have the function of not only hiding the processed surface but also positioning during assembly, there is an advantage that no special jig is required for assembly.

Although the above explanation has been about the assembly of the vertical stile 1 and the horizontal stile 2, the same assembly structure is also used for the assembly of the vertical stile 1 and the horizontal stile 3, or the horizontal stile 2 and the vertical stile 4. .

Claims (1)

[Scope of utility model registration request] Left and right stiles, upper and lower horizontal stiles, and an appropriate number of horizontal stiles in the middle,
In aluminum doors that are assembled with a horizontal stile and a horizontal stile, or a vertical stile between a horizontal stile and a vertical sill, and a decorative panel is fitted in the section separated by the stile or the sill, the horizontal stile and horizontal sill are more important than the vertical stile. The wall thickness is made large, and the wall thickness of the vertical stile is made larger than that of the horizontal stile and horizontal stile, and projections 6, 6 are provided parallel to the inner edges of the vertical stile, horizontal stile, and horizontal sill to form a recess 7. The aluminum door is characterized in that these four parts are joined by fitting the ends of small, thick frames or crosspieces.
