BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint portion of a folding type horizontal pull shutter which can be opened and closed along a curved track.

[0002]

2. Description of the Related Art In recent years, folding horizontal pull shutters as shown in FIG. 6 have been widely used for various entrances, show windows, partitions and the like. In such a horizontal pull shutter, the longitudinal edges of a plurality of shoji door pieces D1, D2 ... Dn are foldably connected via a joint J1, or J2 such as T-number, and every other odd number Joints J of door pieces D1, D3 ...
1. A suspension vehicle is provided on the upper part of the vehicle, and the suspension vehicle S is used to suspend the suspension vehicle from the hanger rail R in the Kamoi frame A.
... Dn is stored in the storage case C on the hanging frame F side in a folded state. Then, the folding door pieces folded in the storage case C are sequentially pulled out by the puller frame G, so that the upper and lower ends of the respective door pieces D1 to Dn are fitted into the orbit frames of the Kamoi frame A and the sill frame B and are guided along the orbit. , You can move straight ahead.

By the way, such a foldable horizontal pull shutter is required not only to open and close along a straight track, but also to open and close along a curved track. That is, in order to open the entrance and the show window as fully as possible, it is necessary that the storage case is arranged on the side surface and the shutter pulled out from the side surface is curved at the corner and guided to the front. Generally, since the folding type horizontal pull shutter is fitted into the Kamoi frame A and the sill frame B and guided by the orbit, there is a structural difficulty that it is curved and difficult to move, though it has a lot of straightness. As a conventional technique that has solved the above problem, there is known a "curved track structure of a foldable horizontal pull shutter" according to Japanese Utility Model Laid-Open No. 60-179793.

This is because the track for guiding the even-numbered joint J2 of each door piece, that is, the joint J2 on which the suspension vehicle S is not mounted, is wide at the corner portion, and the joints J2 and J2 can be curved and moved in a straight line. I am trying. However, in such a method of enlarging the track width, the radius of curvature of the corner is also limited, and inevitably a large radius of curvature must be taken,
Also, the width of each door piece must be reduced. Therefore, the increase in the number by reducing the width of each door piece not only increases the manufacturing man-hours of the shutter itself, but the increase in the radius of curvature of the above-mentioned corner portion leads to the reduction of the internal space,
Furthermore, the expansion of the orbit width also results in a decrease in airtightness.

Furthermore, as a prior art, Japanese Utility Model Application No. 61-77
The "folding type horizontal pull shutter" according to No. 991 is also known, and the shutter is a case where the entire track is curved, and since each door piece is also curved and has the same radius of curvature as the track, it is connected. , Can not be adopted for a straight track. In addition, when the curved door piece is folded, the door pieces cannot be folded because they are completely in close contact with each other, and the storage case becomes very large.

[0006]

As described above, since the folding type horizontal pull shutter is housed in the storage case, each door piece is allowed to bend only in the opposite direction at each joint portion, so that the straight line shutter is straight. It is good to move in a curved orbit, but when bending the corners, that is, because it is not possible to bend in the same direction at each joint,
The curved trajectory cannot be freely advanced, and the above-mentioned problems remain in the conventional technology. The present invention is a technology devised with the aim of solving these problems, and by improving the joint part, a shutter that connects door pieces of the same size as before can be smoothly cornered without expanding the track width. The joint part of the shoji door piece of the shutter that can be moved in the part is provided.

[0007]

In order to solve the above problems, the joint portion of the folding type horizontal pull shutter according to the present invention has the following features. In the horizontal pull shutter of the present invention, each door piece is foldably connected by a joint so as to be housed in a storage case, and the joint folds each door piece in the opposite direction in sequence, so that the bending direction is restricted. Therefore, when moving along a curved track, the bending directions of the door pieces at the joints must all be the same.

That is, if the bending direction of the joint J1 having a suspension wheel is set to the inner (positive) direction, another joint J having no suspension wheel is provided.
If the bending direction of 2 is not the outer (negative) direction, each door piece cannot be folded, but in the present invention, since the joint J2 is bent in the same inward direction, an auxiliary shaft is provided at the joint J2 portion. Has a connecting piece. Each joint part is composed of two main shafts, and the bending direction of the door piece is regulated. The joint J2 has two auxiliary shafts juxtaposed outside each of these two shafts. The auxiliary shaft is bent in a direction opposite to the bending direction allowed by the main shaft. That is, the connecting piece is interposed between the door piece and the main shaft without directly connecting the door piece to the main shaft, and a predetermined degree of freedom is given to the bending of the connecting piece and the door piece, and a curved orbit. It is possible to move along. Here, the joint part having the connecting piece can be applied not only to J2 but also to J1. Hereinafter, an embodiment of a folding horizontal pull shutter according to the present invention will be described in detail with reference to the drawings.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a specific example of a folding type horizontal pulling shutter constructed by using a joint portion according to the present invention, which is shown in cross section and shows a state of being pulled out from a partially folded state. ing. In the figure, 1 is a J1 joint,
2 is a J2 joint, 3 is a shoji door piece, 4 is a connecting piece, and each shoji door piece 3, 3, ... Is connected via the J1 joint 1 and the J2 joint 2 so as to be bendable, that is, foldable. Has been done. Here, the J2 joint 2 which is a feature of the present invention will be described. The J2 joint 2 has a frame member 5 in the center thereof, and main shafts 6, 6 are formed on both sides of the frame member 5. A connecting piece 4 having a small width is swingably connected to the main shaft 6, an auxiliary shaft 7 is formed at the other end of the connecting piece 4, and a small stopper 8 is provided on the outer periphery of the auxiliary shaft 7. Is protruding.

Here, both the main shaft 6 and the auxiliary shaft 7 may be formed at both ends of the connecting piece 4, but since each part is processed by extrusion molding, its workability and convenience of assembling are improved. It may be provided on either side in consideration. In this embodiment, a bearing that engages with the main shaft 6 is formed at one end of the connecting piece 4, and the auxiliary shaft 7 is provided at the other end as described above.
The shoji door piece 3 is connected to. That is, in the conventional shutter, the shoji door piece 3 was directly connected to the main shaft 6, but in the present invention, it is connected via the connecting piece 4.
Then, sliders 9 are attached to the upper and lower ends of the frame member 5,
Similarly, the sliders 9 are provided at the upper and lower ends of the auxiliary shaft 7, and these sliders 9 are housed in the track 11 of the sill frame 10 and guide the shoji door pieces 3, 3 ,.

On the other hand, the J1 joint 1 is the same as the conventional shutter, and main shafts 13 and 13 are formed on both sides of the frame member 12, and the main shaft 13 is connected to the auxiliary shaft 7 by a shoji door piece. The other end of 3 also forms a bearing and is connected.
A suspension wheel 18 is attached to the upper end of the main shaft 13 and a slider 14 is attached to the lower end thereof, and is guided along the track 11. FIG. 2 is a sectional view taken along the line AA in FIG. 1, showing a state where the sliders 9 and 14 are housed in the track 11 of the sill frame 10, and FIG. 3 shows a sectional view taken along the line BB in FIG. . In FIG. 3, since the shutter is folded, the height of the guide wall 15 of the sill frame 10 is low so that the guide wall 15 can be separated from the track 11 when folded.
However, the slider 14 attached to the main shaft 13 of the J1 joint 1 has a high height and is always accommodated in the track 11. Further, in FIG. 4, the shutter is folded and the storage case 16 is shown.
As shown in the same figure, the upper end of the J1 joint 1 travels on the kamoi frame 17, and a suspension vehicle 18 for supporting the shutter is attached. The shutter is opened and closed smoothly.

By the way, FIG. 5 shows a state in which the shutter having such a joint moves along the curved track 11. As you can see from the figure, J
In the one joint, the shoji door pieces 3, 3 connected to both sides around the main shaft 13 of the frame member 12 can be bent inward along a curved curve. This bending direction is the same as the direction in which the shoji door pieces 3, 3 are folded, and the bending in the opposite direction is restricted by the base 19 of the main shaft 13 serving as a stopper, but bending in the inward direction is allowed. ing. Therefore, the slider 14 of the J1 joint 1 can move along the curved track 11. On the other hand, J2 joint 2
Is not allowed to bend inwardly of the connecting pieces 4 and 4 which are connected to the main shafts 6 and 6 provided on both sides of the frame member 5.
The auxiliary shafts 7 formed on the outer ends of the connecting pieces 4 are all aligned.

However, since the shoji doorway 3 connected to the main shaft 13 of the J1 joint 1 is connected to the auxiliary shaft 7 and is allowed to bend at a predetermined angle around the auxiliary shaft 7 of the connecting piece 4. It can move along a curved track 11. Here, the three sliders 9 and 9 attached to the J2 joint 2 part are arranged in a straight line.
Since there is some gap between the guide walls 15 of No. 1,
It is fully movable. In addition, the stability of each shoji door piece 3 connected through the auxiliary shaft 7 in this way is as described above with respect to the force from the inside, the force acting from the outside, and the returning force centering on the frame member 5. The connecting piece 4 is stable by engaging the root of the main shaft 6 and the stopper 8 of the auxiliary shaft 7, and the protruding position of the stopper 8 and the shape of the connecting piece 4 are taken into consideration so as to prevent rattling. As described above, the following effects can be obtained by using the joint portion of the present invention as the connecting means for the shoji door pieces of the folding horizontal pull shutter.

[0014]

[Advantage of the Invention] The folding type horizontal pull shutter uses each connecting door piece 3 by using a connecting piece having an auxiliary shaft at its joint.
All of 3 ... can be bent along a curved orbit, and the lateral pulling shutter can be curved with an orbit of the same width without enlarging the orbit width at the corner portion unlike the conventional case. By making the track widths the same, the airtightness with the outside is improved, not only is it effective in preventing rattling of the shutter itself, but it is also possible to reduce cooling and heating costs, and In the curved movement due to the expansion of the track width, the radius of curvature of the corner portion of the track is restricted, and it is unavoidable that the track has a large radius, and the internal space is reduced accordingly. In the present invention, a trajectory having a corner with a small radius of curvature can be realized.
On the other hand, even if the connecting piece is used in the joint portion, the auxiliary shaft forms a stopper that allows a slight rotation only in the direction opposite to the folding direction, so that the regular folding operation is not hindered.
