Description

[Detailed Description of the Invention] The present invention relates to a continuous hinge for assembling an extensible frame used mainly for partitions such as accordion curtains.

Some conventional hinges of this type are made by connecting a pair of hinge pieces that have connecting parts at both ends in an X shape, and connecting a plurality of hinges with the crossed parts pivoted. Accordion curtains are made by assembling a telescoping frame by connecting several continuous hinges in the shape of horizontal bars at appropriate intervals, and covering both sides of the telescoping frame with a decorative covering material such as vinyl leather. When unfolding or folding it by attaching it, due to the tensile phenomenon of the decorative covering material, after the continuous hinge reaches the limit length of extension or the limit length of shortcoming,
Since it is pulled back a little in the opposite direction, it has the disadvantage that the opening and closing of the frontage is incomplete and unsightly.

The present invention aims to provide a continuous hinge that can overcome these conventional drawbacks.

Below, the embodiments of the present invention will be explained based on the drawings: 1
1 is a hinge for assembling a connecting hinge according to the present invention, which consists of a pair of hinge pieces 4 having a bifurcated connecting ring 2 at one end and a connecting ring 3 at the other end that can be fitted into the crotch of the connecting ring 2. , 4 are intersected in an X-shape by fitting the notches 5, 5, which are half of the width of the plate at the center thereof, and the shaft bearings 6, 6 are provided at positions corresponding to the intersections. Axis pin 7
It is more powerful than the structure where it is inserted.

8, 8 is a shaft bearing part 6 on each hinge piece 4, 4 in the hinge 1.
The reinforcing ribs are formed from the vicinity to the connecting rings 2, 3 at both ends, and the inside of each hinge piece 4, 4 is depressed by press working, and the outside is raised to prevent it.

9.9 is the bifurcated connecting ring 2, among the reinforcing ribs 8, 8,
A long hole is drilled in a part of the reinforcing ribs 8, 8 toward the end portion having 2; a locking piece 11 that locks the spindle tape sewn on the back side of the decorative covering material;
It has 11.

A plurality of hinges 1 configured as described above are connected by fitting the connecting ring 3 into the connecting ring 2 and inserting a shaft pin to assemble the connecting hinge 12 as shown in the fourth figure.

Reference numerals 13 and 14 denote single hinges connected to both ends of the continuous hinge 12, and U-shaped presser fittings 15 and 16 are attached to the pivoting portions 7 of the single hinges, and wooden vertical bars 27 and 14 are fitted inside the hinges. At the same time, the end of the decorative covering material described later is fixed, and an adjustment stile is attached to the outside thereof to adjust the spacing between the decorative stile and the frontage.

At both ends of the shaft pin connecting the connecting rings 2 and 3 in the connecting hinge 12, there are terminals 18 for fixing a vertical frame rod 17 having a gutter-like cross section as shown by the dotted line in FIGS. 4 to 6. ．．
18 is the provision.

Incidentally, a recess is provided between each connecting ring 2, 3 and the hinge piece 4, but this is done by fixing a gutter-shaped vertical frame rod 17 to each terminal 18° 18 and extending the continuous hinge 12. When this happens, both edges of the vertical frame rod 17 are retracted, and both ends of each hinge piece 4, which is opened around the pivoting part 7, are connected to the vertical frame rod 17.
This prevents it from hitting the edges on both sides.

Reference numeral 19 denotes a slide component that slides along the long holes 9, 9 of each hinge 1, and this is a slide component that slides along the long holes 9, 9 of each hinge 1, and this is a slide component that slides along the long holes 9, 9 of each hinge 1.
A through hole 22 is formed in the standing part 21 which is made by punching out the plate surface of 0.
1, every other hinge connection part 23 in the continuous hinge 12 is connected every 23, and the hinges on opposite sides are connected from each pivot part 7°7 of the adjacent hinges 1, 1. Connecting part 23.23
In the hinge pieces 4, 4 leading to the slide part 19, the base plate 20 thereof contacts the inside of each hinge piece 4, 4, and the upright part 21 protrudes to the outside of each hinge 4°4 through the elongated hole 9, 9. The slide parts 19 and 19 are slidably fitted together, and a spring 24 is suspended between the through holes 22 and 22 of each of the slide parts 19, thereby assembling the continuous hinge according to the present invention.

Next, the operation of the continuous hinge constructed as described above will be explained. When the continuous hinge 12 is in the shortened state as shown in the fourth figure, the slide parts 19, 19 are moved by the tension of the spring 24 into the respective elongated holes 9, 9 towards the hinge shaft attachment part 7, and when they are pulled together, the spring 2
4 maintains its own length, that is, the length in the unextended state, and a force that holds the slide part 19.19 in the above-mentioned drawn position acts on each hinge piece 4, 4, so that the entire continuous hinge 12 reaches its shortening limit length. Tighten.

When the continuous hinge 12 in this shortened state is extended, the distance between the slide parts 19 and 19 is widened, and the spring 24 is extended.

When the continuous hinge 12 is extended to about half of the maximum extension length as shown in FIG. 19, due to the tension accumulated in the spring 24, the opposite side of the elongated holes 9, 9, that is, the hinge connection part 2
3.23 side, and a force acts on each hinge piece 4, 4 to move the opposing hinge connecting parts 23.23 closer to each other with the spring 24 in between, so that the entire continuous hinge 12 becomes self-cutting. Then, as shown in Figure 6, it is extended to the limit length and stops returning.

When shortening the continuous hinge 12 that has been extended as described above,
When the spring 24 is shortened to half its length, the spring 24 is stretched to its maximum extent, and when the connecting hinge 12 is further shortened, each sliding part 19.19 is pulled out of the elongated hole 9.9 by the tension accumulated in the spring 24. is pulled back to its original position, and the entire hinge 12 is shortened by its own blade to the shortening limit length as shown in the fourth figure, and stops returning.

In addition, when assembling an extensible frame such as an accordion curtain using the above-mentioned continuous hinge 12 and applying decorative covering material 25 such as vinyl leather to both sides of the frame as shown by the dashed lines in FIGS. 4 to 6, The spindle tape 26 sewn to the back surface is locked to the locking pieces 11, 11 of the tension rope 10 attached to the shaft pin 7 of each hinge 1.

Then, when folding an accordion curtain or the like, each tension rope 10 pulls the decorative covering material 25 into each valley of the continuous hinge, folding the decorative covering material 25 in an orderly manner, and when unfolding an accordion curtain or the like, each tension rope 10 cable 10
operates to make the decorative covering material 25 stretch flat.

In the above embodiment, an example was shown in which a long hole is drilled in the reinforcing rib from near the pivoting part of the hinge piece toward the connecting part at both ends.
However, the present invention is not limited to this, and the hole may be formed in a flat hinge piece, and the side edges of the hinge piece may be bent to be reinforced.

Further, the suspension position of the spring with respect to the continuous hinge can be changed as appropriate, in addition to being placed at every other hinge connecting portion as in the above embodiment.

Further, the design of the hinge for assembling the continuous hinge, the slide component, and the elongated hole for sliding it can be changed as appropriate.

Since the present invention is constructed as described above, when an extensible frame such as an accordion curtain is assembled, decorative covering material such as vinyl leather is applied to both sides of the frame, and the tension of each spring is expanded or folded, the tension of each spring is reduced. To overcome the tensile force of the covering material, stably support the accordion curtain in the unfolded or folded state, and prevent it from returning.
The frontage can be opened and closed completely, eliminating the unsightly appearance of conventional accordion curtains when opening and closing.

Moreover, when the unfolded or folded width exceeds half, the frontage is opened and closed by its own blade, which has practical effects such as ease of opening and closing operations.
