Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a mounting device for attaching a wing member to a surrounding frame of a fitting such as a louver or a louver, in which a wing member is attached to the surrounding frame.

BACKGROUND ART Wing members such as louvers or louvers are usually fixed to the vertical frames on both sides of the surrounding frame with tapping screws, or by fitting into cut grooves or press-formed grooves formed in the vertical frames. but,
When using tapping screws, it is very troublesome and the work efficiency is low if there are a large number of blade members, and there are also drawbacks such as making holes in the vertical frame, which is disadvantageous in terms of waterproofing. With the push-in type, it is difficult to create accurate grooves, and
Since the entire blade member is fixed using an aluminum spring presser, there is a drawback that play inevitably occurs between the blade member and the vertical frame, resulting in a harsh sound in strong winds.

Furthermore, in the louver member mounting device disclosed in Japanese Utility Model Application Publication No. 56-133090, a leg piece is fixed in advance to the end of the louver member (wing member), and the leg piece is inserted into the engagement groove of the upright frame. In addition, in the structure for assembling a louver in Japanese Utility Model Application Publication No. 58-19094, the louver is assembled by stacking fixed pieces incorporating 3 to 4 louver blades on a vertical frame. Each configuration is disclosed. However, the leg pieces or fixing pieces disclosed in these documents simply fit the leg pieces or fixing pieces into the engagement grooves, so a gap is still generated between the leg pieces or the fixing pieces and the groove wall, which prevents the play of the louver member. There are deficiencies that cannot be resolved.

Problems to be Solved by the Invention The object of this invention is to provide a device for efficiently attaching a blade member to a surrounding frame without making holes in the surrounding frame, and without backlash.

Means for Solving the Problem A plurality of identical brackets each having a blade member attachment part and a fitting part, and a mounting groove having engaging protrusions facing each other on both sides of the opening and protruding in a direction that narrows the opening. The surrounding frame constitutes a device for attaching the blade member to the surrounding frame.

The fitting portion of the bracket has a contact portion that comes into contact with the engaging protrusion of the mounting groove from the inside of the groove, and has overlapping portions at both ends along the longitudinal direction of the mounting groove.

When such a bracket is placed in the mounting groove, its fitting portion overlaps the overlapping portions at both ends within the mounting groove in the depth direction of the groove, and the overlapping portion is between the groove bottom of the groove and the engaging protrusion. Insert it so that it is crimped.

Embodiment FIG. 2 shows a fittings louver as an example of an article in which a wing member is attached to a surrounding frame.

The louver 1 is constructed by mounting a plurality of louver blades 3 (blade members) horizontally and at equal intervals on a surrounding frame 2 assembled in a square manner.

As shown in FIGS. 3 and 4, mounting grooves 5 that open toward the outdoors are vertically formed in the vertical frame 4 on both sides of the surrounding frame 2. This mounting groove 5 has an engaging protrusion 6 and a groove bottom 7 (FIG. 1) in a cross section, and the engaging protrusion 6 faces each other on both sides of the opening of the mounting groove 5 in a direction narrowing the opening. It protrudes toward (Figure 4).

The width of the mounting groove 5 is w1, the depth of the groove (in this case,
Assume that the dimension (indoor/outdoor direction) is S1. In addition,
When the louver blade is horizontal and long, an intermediate frame having a mounting groove 5 may be provided upright in the middle of the peripheral frame 2 in the width direction in order to prevent the blade from loosening.

The louver blade 3 is mounted horizontally between the vertical frames 4 on both sides by fitting the brackets 8 engaged at both ends into the mounting grooves 5 (the first
Figure) The bracket 8 is made by cutting a long extrusion-molded member having the cross-sectional shape shown in Figure 5A horizontally with a width w1 to obtain a material 9, which is then formed into the shape shown in Figure 5B.

Since each part of the material of this bracket 8 is plate-shaped, it has elasticity to the extent that it bends when strongly pressed in a direction perpendicular to the plate surface.

As shown in FIG. 6, the bracket 8 is composed of a fitting part 11 on the indoor side and a blade member mounting part 12 on the outdoor side, with this plane as the boundary. has been done.

The fitting part 11 has one overlapping part A at one end (upper side) of the base part 13 and the other overlapping part B at the other end (lower side), and these overlapping parts A and B have a bulge 14 bulging toward the indoor side. , 15 are formed respectively. base 1
3 has an abutment ridge 16 at the lower end, and a base 13
A base engaging ridge 17 is formed in the middle of the outdoor side surface of the holder, projecting slightly toward the outdoor side from the only surface P of this portion.

The blade member attachment portion 12 is located between the connecting portion 18 formed at the end of the overlapping portion A and the outdoor side surface of the base portion 13, and is inclined from slightly above the base engaging ridge 17 toward the outdoor side and slightly downward. Support part 1 extended by
It consists of 9.

The connecting portion 18 is connected to a substrate 20 which is provided parallel to the base 13 and offset toward the outdoor side by the thickness of the base 13, that is, with a step toward the outdoor direction from the upper end of the base 13, and from this through a slight horizontal portion 21. The board 20 has an engagement plate 22 extending obliquely upward to the outdoor side, an upper engagement ridge 23 on the indoor side at the upper end of the board 20, and an edge 24 with a round cross section at the upper end of the engagement plate 22. are formed respectively, and furthermore, an upper engagement groove 25 is formed on the lower surface of the horizontal portion 21.

The support portion 19 has an engagement groove 26 that opens upward at the tip thereof, and a locking protrusion 27 is formed at the center of the lower surface.

As shown in FIG. A notch 35 (FIG. 5B) having a width t and a depth w2 corresponding to the thickness and protrusion amount of 6 is provided on the outdoor side with surface P as a reference. As a result, the outdoor flat surface of the base 13 in the fitting portion 11, the outdoor surface of the contact ridge 16, and the overlapping portion A
A contact portion 10 having a width w2 along the plane P is formed on both sides of the flat surface on the outdoor side of the tip portion.

The overlapping parts A and B are designed so that, when overlapped, the thickness of the overlap becomes slightly larger than the depth S1 of the mounting groove 5 (FIG. 1).

On the other hand, as shown in FIG. 7, the louver blade 3 is composed of an extruded long material having a draining portion 28, a rising portion 29, a slope portion 30, and a falling portion 31 in cross section. An engagement protrusion 32 is formed on the indoor side edge, and an engagement hook 33 is formed on the lower surface of the slope portion 30 on the outdoor side.

Engagement protrusion 32 and engagement hook ridge 3 of louver blade 3

The brackets 8 are attached to both ends of the louver blade 3 (also in the middle if necessary), and the fitting portion 11 is inserted into the mounting groove 5, and the contact portion 10 is inserted into the mounting groove 5. It is fitted and installed in sequence along the indoor side surface of the mating edge 6.

Then, as shown in FIGS. 1 and 6, each bracket 8 has its fitting portion 11 placed within the mounting groove 5.
The lower bracket 8' is attached to the locking protrusion 27 of the support part 19.
The edge 24 of the engagement plate 22 at
The upper engagement ridges 23 of 0 are respectively engaged, the end of the overlapped portion B rests on the ridge 14 in the overlapped portion A of the lower bracket 8', and the end of the base 13 is rested on the ridge 14 in the overlapped portion A of the lower bracket 8'. The overlapping portion A and the overlapping portion B are aligned in the longitudinal direction within the mounting groove 5 while forming an overlapping portion 34 in which the overlapping portion A and the overlapping portion B overlap in the depth direction of the mounting groove 5. Installed in condition.

At this time, the overlapping portion 34 of the overlapping portions A and B is located at the groove bottom 7.
and the portion of the engaging protrusion 6 that is in contact with the abutting portion 10, and due to the reaction force caused by the protrusion 15 in the overlapping portion B being in contact with the groove bottom 7,
The abutting portion 10 of the fitting portion 11 tightly abuts the engaging protrusion 6 of the mounting groove 5 from inside the groove 5.

In the present invention, the overlapping part 34 means a part that is crimped in the mounting groove. For example, the overlapping parts A and B may have a wedge shape. Contrary to the example case, there are cases where they overlap. The abutting portion 10 may not be a surface as in the embodiment, but may be the apex of an uneven surface.

Further, the mounting groove 5 may be arranged not vertically as in the embodiment, but in another direction such as horizontally.

Furthermore, after attaching the brackets 8 to the surrounding frame 2 in advance, these brackets 8
A blade member may be attached to.

Effects of the invention: The mounting efficiency of the bracket to the surrounding frame is very high because the bracket is simply inserted into the mounting groove of the surrounding frame while partially overlapping with other brackets vertically.

When each bracket is fitted into the mounting groove, its overlapping portion is crimped into the groove, so the contact between each bracket and between the bracket and the surrounding frame is tight and there is no looseness due to wind pressure or vibration. It does not emit harsh or harsh sounds.
