JPS5931908Y2 - Angle adjustment device for metal fittings - Google Patents

Description

[Detailed description of the invention] This invention relates to an angle adjustment device for metal fittings made of extruded aluminum, etc., and in particular, to easily adjust the mutual angle between the upper and lower horizontal stiles and the vertical stiles on both the left and right sides of the metal fittings. The purpose is to propose an angle adjustment device that can adjust the angle.

When using metal fittings such as those made of aluminum profiles, it is often necessary to change the length of the frames that form the frame.

For example, when installing metal fittings into an existing building, when the building is aging and the pillars, sills, lintels, etc. are out of alignment, and accurate dimensions are not maintained.
This is due to the fact that the various lengths of these metal fittings must be adjusted and arranged to fit the building.

For this reason, metal fittings are usually equipped with adjustment mechanisms to adjust various length dimensions.
If only the lengths of each type were changed, the entire structure would be bent, which would be inconvenient.

To explain this situation more clearly, in the metal fittings 1 consisting of horizontal stile A and vertical stile B as shown in Fig. 1, horizontal stile A is
If we increase the length dimension a and extend it to the dimension s, the actual shape will be as shown in Figure 1 (not ly, but
The entire shape shown in the second figure is bent (2).

In order to eliminate this deflection, it is necessary to change the mutual angles of the connecting sides of the vertical and horizontal frames.

This invention was created under these circumstances and devised an angle adjustment device for metal fittings, using an angle adjustment fitting C as shown in FIG.

That is, a long hole 4 is provided in the base piece 3, and then, for example, a hole is punched out in a part of the base piece 3, leaving one end, to form an upright piece 5 in a vertical state, and a vertical piece 6 is attached to this in the form of a hinge. It's something I've acquired.

Here, 7 is the hinge mechanism.

A screw hole 8 is provided in this vertical piece 6, and an angle adjustment screw 9 is screwed into it from one side, and its tip is connected to the upright piece 5 of the table piece 3.

10 is a mounting hole provided in the vertical piece.

As shown in Fig. 4, horizontal stile A and vertical stile B are connected by such an angle adjustment fitting C.
Attach pedestal 3 using screws S, while attaching it to vertical stile B.
The vertical piece 6 is attached by screw S'.

As a result, both species become crossed and form a framework.

When adjusting the dimensions of the side stile A to make it longer as shown in Figure 1, as required for the size adjustment for the old building mentioned above, the long holes 4 and the screws S are used to attach the stile A. .

At this time, the angle adjustment screw 9 of the vertical piece 6 is loosened.

As explained above in FIG. 2, the extension of horizontal stile A causes the entire framework to flex, but if the angle between vertical stile B and horizontal stile A is adjusted by moving the angle adjustment screw 9 back and forth, , deflection can be easily eliminated.

5 is a cross-sectional view of the horizontal stile A, and FIG. 6 is a cross-sectional view taken along the line E' in FIG. 4, where the cross-sectional structure of the vertical stile B is clearly shown.

As explained in detail above, according to this invention, by moving the angle adjustment screw forward and backward, the angle between the horizontal stile and the vertical stile of the metal fittings can be easily adjusted according to the angle of the storage frame of the fittings formed in the building. This is very useful in practice.
