Description

[Detailed Description of the Invention] The present invention relates to the structure of an aluminum frame door with a decorative panel.

More specifically, in a door constructed of a frame made of aluminum profiles as shown in Fig. 1, a decorative panel 6 can be easily and neatly installed by one worker in the space surrounded by the aluminum frame. The purpose of the present invention is to provide an aluminum frame door with a decorative panel that can be assembled.

The present invention will be described in detail below in comparison with the prior art with reference to the accompanying drawings.

In Figure 1, 1 is a vertical stile, 2 is an upper stile, 3 is a lower stile, 4 is a middle stile, and 5 is a vertical stile.

The present invention relates to a new mounting structure for a decorative panel 6 to be mounted in an opening surrounded by these frames and crosspieces.

FIG. 2 shows a conventional method for installing such a decorative panel, in which the frame material constituting the door is assembled in advance, and the external decorative panel 6a and internal decorative panel 6b are then installed from both the front and back sides of the opening. After fitting it in, it was tightened with screw 7.

The outer length measuring inner decorative panels 6a and 6b are provided with flanges 8 at the portions that engage with the frame material, and the outer decorative panels 6a and 6b are tightened with the flanges 8 holding the frame material.

In this assembly method, when assembling the decorative panels, the outer and inner decorative panels 6a, 6b must be pressed down and screwed together at the same time, so an assistant is always required.

3 and 4 show an embodiment of the present invention, in which opposing small protrusions 17 are provided on both the inner and outer edges of the built-in side of the vertical stile 1,
A shallow recess 18 is formed between the small protruding edges 17 and 17,
Furthermore, an insertion groove 9 into which the fitting protrusion 10 of the outer decorative panel 6c is fitted is provided in the center of the recess.

Note that although FIGS. 3 and 4 show the engagement relationship between the inner decorative panel and the outer decorative panel that constitute the vertical stile 1 and the decorative panel 6, the upper and lower stile 2, other than the vertical stile 1, 3 or middle crosspiece 4
The same applies to the securing relationship between the decorative panel 6 or the vertical bar 5 and the decorative panel 6.

By the way, the relationship between the thickness dimensions of the vertical stile, upper and lower stile, middle stile, and top stile is as follows.

That is, the thickness t of the vertical frame 1>thickness of the upper and lower frames 2, 3 or the middle frame 4>thickness t2 of the vertical frame 5.

In this case, the inner dimension between the small ridges 17 and 17 provided on the vertical stile 1 is equal to the thickness of the upper and lower frames 2 and 3 or the middle crosspiece 4.

Similarly, the inner dimension between the small projecting edges 17 and 17 provided on the upper stile 2 and the lower stile 3 is set equal to the thickness dimension of the vertical stile 5.

Reference numeral 6d designates an interior decorative panel, and the periphery of the interior decorative panel 6d is provided with flanges 14 each having a different thickness dimension β corresponding to the thickness of the stile or crosspiece with which this panel engages. There is.

Even if the thicknesses of the frames and crosspieces to be assembled differ due to the difference in the thickness dimension β, the outer circumferences of the inner decorative panels 6d to be fitted are all flush.

The four corners of the outer decorative panel 6c have thick boss portions 11, and the boss portions 11 are provided with screw holes 12 to which the inner decorative panel 6d is fixed.

In addition, when the decorative panel 6c is assembled, the inner surface 13 of the outer decorative panel 6c faces the inner surface of the inner decorative panel 6d and is separated by a small distance α (FIG. 4) from the boss portion 11.
The inner surface of the body is removed.

Furthermore, since the fixing bosses 11 are provided only at the four corners and the other parts are made thin, it is possible to reduce the weight of the entire door.

Further, the boss portion 11 is provided with a screw hole 15 into which the inner decorative panel 6d is screwed.

Furthermore, the edge of the outer surface of the external decorative panel 6c protrudes from the outer surface of the stile or crosspiece that engages with it, and the stile,
Since it is set to a predetermined dimension regardless of the thickness of the frame, this overhang dimension γ (FIG. 4) will vary depending on the difference in the thickness of the frame, frame, etc.

As described above, the four sides of the interior decorative panel 6d are always surrounded by frame materials with different thicknesses as described above, so one side is the vertical frame 1 (thickness dimension t is maximum) and this. The opposite side will touch the smallest vertical bar with a thickness of t2, and the remaining two upper and lower sides will touch the upper and lower frames 2 and 3 or the middle frame 4 whose thickness is between the above t and the cherry blossom. One type of internal decorative panel 6 whose outer periphery is formed to correspond to three thickness dimensions.
All you need to do is prepare d.

In addition, the dimensions of the fitting convex portion 10 on the installation surface of the external decorative panel 6c and the insertion grooves 9 provided on each stile/crosspiece are set to predetermined dimensions regardless of the thickness of the stile/crosspiece. Moreover, since the thickness dimensions of the front outer edge portions of the external decorative panels 6c are formed to have the same size, all the decorative panels can be assembled by preparing one type of external decorative panel 6c.

Now, with the above configuration, the door can be assembled using the following method (see Figure 5).

i Assemble the upper and lower frames 2 and 3 and the middle frame 4 vertically to the vertical frame 1 placed horizontally and secure them with screws.

In this case, the inner width (ti) of the small protruding edges 17, 17 of the vertical stile 1 is made equal to the thicknesses of the upper and lower stile 2, 3 and the middle crosspiece 4, so that they fit into each other.

ii Fitting convex portion 10 provided on the periphery of the external panel 6c
Insert it from above between the upper stile 2 and the middle crosspiece 4, between the middle crosspiece 4 and the middle crosspiece 4, or between the middle crosspiece 4 and the drop 3.

iii With the vertical stile 5 horizontal, insert it between the upper stile 2 and the middle stile 4, between the middle stile 4 and the middle stile 4, and between the middle stile 4 and the lower stile 3 in the same way as the exterior side decorative panel 6c. It's crowded.

At this time, since the thickness of the vertical frame 5 is equal to the width between the small protruding edges of the upper and lower frames and the middle frame, it can be easily fitted.

In the case of this vertical bar, it is sandwiched between the decorative panels, so there is no need to secure it with screws.

iv. Insert one more external decorative panel 6c into the upper part of the inserted vertical frame 5, and finally incorporate another vertical frame 1 and fix it with screws.

In this case, the ends of the upper and lower stile and the middle frame fit between the small ridges 17 and 17 of the vertical stile 1.

At the same time, the fitting protrusion 10 of the outer decorative panel fits into the insertion groove 9.

V Once the vertical stile 1 has been assembled, turn the door over, hang the flange 14 of the interior decorative panel 6d on the small edge of the stile material,
Screw the screws 7 into the screw holes 15 of the inner decorative panel and the screw holes 12 of the boss portion 11, and fix at the four corners.

At this time, the presence of the gap α (FIG. 4) enables complete tightening.

As described above, according to the present invention, a. After the external decorative panel is assembled in advance into the insertion groove provided in the frame material and the frame material is fixed, it is turned over and the internal decorative panel is assembled. When assembling, it is necessary to press down the decorative panel material from both sides.

Therefore, one worker can easily assemble the door decorative panel.

b Also, in the conventional method, in order to assemble the frame members in advance, it is necessary to fix the vertical frame to the upper/lower frame and the middle frame, but according to the structure of the present invention, when the external side panel is assembled, Since the frame members are assembled at the same time, there is no need to fix the vertical frame at the length to be inserted.

C. Since the exterior and interior decorative panels only need to be of the same type, there is an advantage that no special consideration is required during assembly.

d When the decorative panels are tightened with screws, there is a gap α between the inner surface of the inner decorative panel 6d and the inner surface of the outer decorative panel 6c, so the inner and outer decorative panels receive a force that causes them to approach each other. At the same time, due to the repulsive force, there is no looseness at the joint between the decorative panel and the frame material, etc., and the decorative panel and the frame material come into close contact.

Furthermore, since they are screwed together through the gap α, the repulsive force acts as a loosening preventer, increasing the reliability of tightening and preventing loosening of the screws due to vibrations or the like.
