Description

[Detailed Description of the Invention] The present invention relates to an improvement of the slat opening/closing structure of movable louver fittings.

Movable louver fittings are also called blind shutters, and are a type of shutter that has a large number of slats connected horizontally within a rectangular door frame, and are equipped with sliding door wheels.
It is used for single- or double-opening doors, or for so-called "fitted" doors that simply fit into the frame of a building.

Various opening/closing structures for blades have been proposed in the past, and most of the structures that have been put into practical use are ones in which the blades are connected at both ends or one end in a link type, and the mechanism inside the vertical frame is complicated. It is.

It has also been considered that a vertical connecting bar is provided in the middle of the slats, and the slats are rotated to open and close by moving the slats up and down, but this is structurally more complicated than the former. Soundproofing also has its drawbacks.

The movable louver fittings of the present invention are an improved version of the latter, in which a connecting bar is provided in the middle of the slats.The siding structure is improved, and the connection structure with the connecting sills is devised. The machine is housed without protruding from the back of the fittings, giving it an elegant appearance, making assembly easier, and eliminating rattling when opening and closing, providing soundproofing measures.

Hereinafter, the movable louver fitting of the present invention will be specifically explained with reference to the drawings.

Figure 1 is a back view of the movable louver fittings, and the door frame, which consists of an upper stile 1, a lower stile 2, and left and right stiles 3, 3, is reinforced in this case by moving middle beams 4, 4 to the left and right in two places. It forms the entire door frame.

For such a door frame, a large number of horizontal span slats 5 are rotatably supported by slat retainers in both left and right frames,
A connecting beam 6 extending from the upper stile to the lower stile is passed through the middle part of the siding,
The blades are opened and closed by the vertical movement of this connecting bar.

The shape of the vane is shown in FIGS. 2 and 4, and the shape of the vane holding material is shown in FIGS. 3 and 4.

As seen in the cross-section of FIG. 2, the blade plate 5 has an upper portion slightly curved to form a curved portion 7, a clip tapping hole 8 is provided continuously from left to right on the upper edge of the curved portion, and a clip tapping hole 8 is provided in the lower portion of the curved portion. A movable pin tapping hole 9 is provided, and a water cut edge 10 is formed at the center of the curved portion at a nearly right angle to the curved surface.

Further, when the lower edge portion 11 of the blade plate 5 is slightly curved inward, the entire blade plate becomes rounded and has a preferable shape.

Such a vane plate is preferably manufactured by extrusion molding of an aluminum material.

The slat 5 is held against the stile 3 by a slat holding material 12 provided inside the stile 3.

As shown on the right side of FIG. 3, the blade holding material 12 is made by inserting a metal core material 14 into a gasket 13 made of extruded polyvinyl chloride to increase its strength, and penetrating the gasket and the core material. Feather board support holes 15 are provided at regular intervals, and soft tubes of polyvinyl chloride are welded to each of the holes to prevent rattling and provide waterproof properties.

Rotating pins 16 inserted and fixed into pin tapping holes 9 are sequentially inserted into this blade support (L15) to rotate the blade.

Here, if a bushing made of nylon, for example, is fitted to the rotation pin 16, there will be no increase in rotation resistance due to the occurrence of rust, and in conjunction with the structure of the blade holding material described above, stable support is ensured.

The screws 17 are for fixing the blade holding material 12 to the vertical stile 3.

In this way, the stile simply holds a large number of slats by attaching the slat retaining material inside, and there is no rotating device inside the stile, making it easy to assemble and install the sills. There is.

Therefore, the slats are opened and closed by vertical movement of the connecting beam 6 extending from the upper stile to the lower stile in the middle of the sill.

The details are shown in FIGS. 2 to 4, and FIG. 4 is an exploded perspective view showing how each member is connected.

That is, the curved portion 7 at the intermediate portion from approximately the left and right ends of the blade plate.
The clip tapping hole 8 on the upper edge of the curved part is exposed to the left and right with a predetermined width by cutting out the clip tapping hole 8 of the upper edge of the curved part, and the U-shaped connecting bar 6 as a basic structure is fitted into the notch 18, and the clip tapping hole 19 of the connecting bar and the above-mentioned clip are inserted. It is assembled by aligning the tapping holes 8 and locking them with the Q-shaped spring clips 20.

If nylon bushings are fitted to both ends of the spring clip 20, the soundproofing effect will be improved.

The connecting bar 6 has side edges 21 on both sides thereof to hide the notch 18 of the blade plate, and the cover 22 is fitted onto the connecting bar 6, leaving aside the spring clips, for a good appearance.

Its cross section is as shown on the left side of FIG.

The rotation angle of each blade plate can be set arbitrarily by the vertical stroke of the connecting bar, but as shown in Figure 2, it is approximately 60 degrees when opened.
The degree of rotation is most preferable both in terms of appearance and functionality.

The cut edges 10 of the slats 5 serve not only as drains but also as a cover when closed and to improve security.

As described in detail above, the movable louver fittings of the present invention have been specially devised in the shape of the slats, their holding structure, and opening/closing structure, and as a result, they have an elegant appearance, a simple structure, and are fully capable of functioning as louvers or blinds. This resulted in a good product.
