Description

[Detailed Description of the Invention] This invention relates to a folding opening/closing support device used for shutters, louvers, etc.

Conventional shutters, louvers, etc. have a feature that their folded dimensions are smaller than those of ordinary sliding doors and shutters, but they are still quite large.

However, even if only the panels are stacked on top of each other, the size will not be that large.

The increase in size is due to the large dimensions of the parallel motion links, panel joints, and hanging wheels that support them.

On the other hand, dirt gets into the lower rail, and as a result, the folding door, which is flexible as a whole, may not move upward and downward at the same time, resulting in awkward movement, and the rail surface may be damaged, resulting in uneven movement.

That is, durability is low. This invention has been made with attention to these points, and the object is to provide a lower rail and guide for a folding device with a small folding dimension suitable for shutters, louvers, etc.

Another object of this invention is to provide a durable lower rail and guide that allows smooth movement without dirt accumulation on the lower rail.

This idea is based on a movable piece that engages with the upper rail, and two guide strips are installed on the lower rail in response to the structure that allows the panels and joints to be folded into a small size.These guides are alternately guided to every other joint of the folding door. The guides are attached and every other guide is engaged with each guide, but the guide grooves face downward and the upper part of the guide grooves is closed.

Embodiments of the rain shutters of this invention will be described below with reference to the drawings.

FIG. 1 is a schematic front view of the folding shutter as seen from the outside, FIG. 2 is a schematic vertical sectional view of FIG. 1, and FIG. 3 is a schematic plan view of FIG. 1.

Folding shutters have 1 upper rail, 2 lower rails, and 3 panels.
, joints 4 and 5.

4 and 5 are enlarged cross-sectional views taken along lines A-A and B-B in FIG. 1, respectively, and FIG. 6 is a cross-sectional view taken along line H-H in FIG. 4.

The upper rail 1 has two upper and lower protrusions, and a guide member 6,
7, and a guide member 8 that hangs down from the end extending outward.

A T-groove is formed in the upper part.

There are no guide members in the storage section 9 or its vicinity, and the guide members 6,
7 extends over the entire length of the upper rail 1.

Near the storage area 9 are the guide scraps 8 and the blindfold 7
' is provided on the inside to block light.

The panel 3 is joined by forming joints 4.5 on both sides of the panel plate 3A and the panel plate 3B, respectively.

The joints 4.5 are formed by forming the ends of the panel plates 3A and 3B into cylindrical columns 21A, 22A, 21B, and 22B and cutting them out alternately so that they fit into the T-shaped piano.

Projections are formed on the cylindrical columns 21A, 21B to serve as stoppers 23A, 23B.

Panel 3A. The stopper 23A and the panel plate 3 intersect at a position where 3B intersects at a large angle with the joint 4 as the apex.
The ends of the stopper 23B and the end of the panel plate 3A are brought into contact with each other.

As shown in FIGS. 4 and 5, the upper part of the joint 4 has a rectangular plane shape, and the lower part has guide members 6, 6 and 7,
Shafts 26.27 with flanges attached to the upper ends of slides 24.25 with fitting parts that loosely fit between the shafts 26.27 are alternately and tightly fitted into the uppermost cylindrical columns 21B, and respective retaining rings 28 are fitted into the shafts 26.27. It is.

The slides 24, 25 are moving pieces that slide on the guide members 6, 7.

As shown in FIGS. 7 and 8, the lowermost cylindrical columns 21
A shaft 3.2 is tightly fitted into each of the shafts B via guides 29, 31, and the shaft 32 is locked by a retaining ring 33.

The guides 29, 31 are therefore pivotally connected to the shaft 32, and the L-shaped extending ends (see Fig. 14), which are bent flat plates, fit into the guide grooves 19, 20 with a small gap and are inserted into the grooves 10, 1i. It is entering.

Therefore, the guides 29, 31 are rotatable relative to the panel plates 3A, 3B during movement, and their L-shaped extending ends are located in the guide groove 19.
20, so that the lower end of the joint 4 does not move inwardly or outwardly.

A mandrel 30 is loosely fitted into the cylindrical columns 21A and 22B of the joint 5.

A bush 35 is fitted into the uppermost cylindrical column 22A except for the joint 4-0.4-f at the inner surface of the joint 4, so that the mandrel 34 is locked by the upper flange of the mandrel 34.

A bracket 3 fixed to the frame is installed in the T groove of the upper rail 1.
6 is fitted, and the flange 18 of the lower rail 2 is fixed to the frame.

Alternatively, the inner member of the upper rail 1 may be extended upward and attached to the frame at that portion, or alternatively, it may be formed integrally with the upper frame of the opening.

Reference numeral 37 shown in FIG. 3 is a stopper at the storage end, 38.3
8' is the latch when the folding shutter is closed, and 39 is the latch when it is opened.

The stopper 37 and the leftmost panel plate 3A end are locked.

Next, I will talk about the effects of this idea.

In FIG. 3, the state indicated by the two-dot chain line is the state in which the folding shutters are open.

In this state, as shown in FIG.
7, and therefore the adjacent sliders 25 are also close to each other.

As shown in FIG. 9, the guides 29 and 31 are located at positions where their tips overlap.

If you remove the latch 39, free the folding shutter, and extend the end to the right in Figure 3, you will see the rightmost panel boards 3B and 3.
At A, the first joint 5-1 of the joints 5 moves inward, and the panel plates 3A and 3B rotate about the shaft 30 at that point.

If the upper part of the joint 4o at the end of the panel board 3B is supported as shown in FIG. 4, and the lower part has the structure shown in FIG. The child 25 is guided by the guide member 6 and slides.

The lower part is guided to the guide groove 19 by the guide 29 via the shaft 32 .

The panel plates 3A and 3B rotate and the angle between the panels increases with the joint 5-□ at the apex, but the guide 2
9 is pivotally attached to the panel plate 3B and rotates to conform to the guide groove 19.

When the stopper 23A comes into contact with the end of the panel board 3B, the force that pulls the end of the folding shutter is applied to the first panel board 3B on the rightmost side.
, is transmitted to the panel plate 3A engaged via the joint 5-□, and the joint 4-1 with the second panel plate 3B is transmitted.
It is transmitted to

At this joint 4-4, the second panel plate 3B is pulled to the right via the shaft 34.

The upper part of this joint 4-□ is shown in FIG. 5, and the lower part is shown in FIG.

In this state, when the first panel board 3B is moved to the right, the joint 5- of the first panel board 3B and the panel board 3A is
The upper part of □ enters into the guide member 8.

The second joint 5-2 from the right side of the joint 5 of the second panel plate 3B and the second panel plate 3A moves inward, and the stopper 23A of the joint and the end of the panel plate 3B are brought into contact with each other. come into contact with

In this way, when the panel plates 3B and 3A are sent one after another to the right, the panel 3 is pulled out.

The right end of the first panel board 3B is locked to the latch 38.

Of course, the shutter can also be closed by pulling the first panel board 3B to the right.

To open the folding shutters, use latch 38 or latch 38'
After removing it and freeing it, apply force to the left in Figure 3.

At this time, force may be applied to either panel 3A or 3B to move it to the left.

In Fig. 3, when a force is applied to the left by holding the first panel plate 3B on the right end, the folding shutter will be prevented from moving the joint 5 to the outside by the guide 8, and the part with the guide member 8 will not change its shape. Go left.

Since the joints 5 of the panel boards 3A and 3B that have reached the storage section 9 become free, the panel boards 3A and 3B are folded in the direction from which the joints 5 face outward.

At this time, the upper part of the joint 4 is supported by the slides 24 and 25, and the lower part is connected to the guide groove 19.2 through the guides 29 and 31.

After storage, lock the latch 39. In Figure 3, when opening the folding shutter from a certain position on the left side of the opening, the latch 38
' is convenient to use.

After removing the latch 38', when you grab the panel plate 3At3B or the joints 4 and 5 and pull them into the storage section 9, the joint 5 moves away to the outside in the storage section 9, and the panel 3 is folded, but the guide member 8 Panel board 3A is drawn in at a certain part.

3B is moved linearly by the stoppers 23A and 23B coming into contact with the ends of the mating panels and being pulled.

The folded state of the panel 3 is shown in FIG.

As mentioned above, according to the lower rail and guide of the folding door of this invention, the guide member is composed of two strips, so
Although adjacent joints 4 can be very close to each other in the folded state, the guide can be widened and movement becomes smooth.

Since the lower rails are closed at the top and open at the bottom, dirt does not accumulate between the rails and is durable.

In addition, the upper surface can have a smooth water gradient, making it convenient for keeping out rain and sweeping it out, and the design has a simple appearance that allows for easy drainage.

FIG. 13 shows another embodiment of the lower rail 2 and guide shown in cross section similar to FIG. 7.

The lower rail 2a is a vertical member 14a*15a that hangs down.
t 16a are each made of a simple plate without any bulge, and the grooves between them serve as guide grooves, and the guides 29,
Projecting pieces 41 and 42 are fixed to 31 in the longitudinal direction of the lower rail, respectively.

The projecting pieces 41 and 42 are made of a polymeric material such as nylon to improve sliding.

To attach it to the main body, screw the key-shaped end of the base material.

Figures 15 to 17 show other embodiments of this invention.

FIG. 15 shows a structure in which the storage portion 19a is provided inside and there is no protrusion on the outside.

FIG. 16 shows an embodiment in which the folding shutter is installed in a cylindrical opening, and the upper and lower rails of the folding shutter are arcuate and the cross section is the same as that of the first embodiment.

In this case, the stoppers 13A and 13B should be in contact with the ends of the adjacent panels when closed, and the portions of the slides 14 and 15 that engage the guide members 6 and 7 should have a shape that follows the guide members 6 and 7. The tips of the guides 19 and 21 are shaped to follow the grooves 10 and 2G, or have a shape with sufficient play.

Figure 17 shows a combination of arcs and straight lines for the upper and lower rails of a folding shutter.

In this embodiment, if the radius of the arc portion is small, the stopper 23B at the joint 4 is not provided.

A clearance is provided between the slides 24 and 25, the upper rail, the guides 19 and 21, and the lower rail so that they can move in arcuate portions and straight portions.
